As part of this leadership transition, Mr. Markison assumed the role of Executive Chair of the Board as of January 23, 2024 until the effectiveness of his Chief Executive Officer appointment in March, and Board Member Julie McHugh became Lead Independent Director.
Strategic Agreements with Perspective Therapeutics
On January 9, 2024, we announced that we entered into multiple strategic agreements with Perspective, a radiopharmaceutical company that is pursuing advanced treatment applications for cancers throughout the body. Under the agreements, we obtained an option to exclusively license Perspective’s Pb212-VMT- ⍺-NET, a clinical stage alpha therapy in development for the treatment of neuroendocrine tumors, and an option to co-develop certain early-stage therapeutic candidates targeting prostate cancer using Perspective’s innovative platform technology for an aggregate upfront payment of $28 million in cash. We also agreed to purchase up to 19.9% of Perspective’s outstanding shares of common stock for up to approximately $33 million, subject to Perspective’s completion of a qualified third-party financing transaction and certain other closing conditions. In addition, Perspective agreed to acquire the assets and associated lease of our radiopharmaceutical manufacturing facility in Somerset, New Jersey. Following satisfaction of the closing conditions, on January 22, 2024, our subsidiary, Lantheus Alpha purchased 56,342,355 shares of Perspective’s common stock at a purchase price of $0.37 per share in a private placement transaction. The total consideration for the purchase was approximately $20.8 million in cash, which resulted in Lantheus Alpha holding approximately 10.74% of Perspective’s common stock as of the purchase date and retaining the right to purchase additional shares to bring its ownership up to an aggregate of 19.9%.
Exclusive License for PNT2002 & PNT2003
On December 20, 2022, we announced the closing of a set of strategic collaborations with POINT, in which we were granted a license to exclusive worldwide rights (excluding Japan, South Korea, China (including Hong Kong, Macau and Taiwan), Singapore and Indonesia) to co-develop and commercialize POINT’s PNT2002 and PNT2003 product candidates. PNT2002 is a PSMA-targeted radiopharmaceutical therapy in development for the treatment of metastatic castration-resistant prostate cancer (“mCRPC”). PNT2003 is a somatostatin receptor (“SSTR”) therapy with non-carrier added lutetium-177, which is in registration to treat patients with SSTR-positive neuroendocrine tumors.
On December 27, 2023, Eli Lilly and Company announced the completion of its acquisition of POINT. The acquisition is not expected to impact the status of the license agreements related to these product candidates or the work being performed in connection with those license agreements and our collaboration with POINT.

PNT2002
With respect to PNT2002, POINT is generally responsible for funding and development activities required for FDA approval, including generating all clinical and nonclinical data, analysis and other information, and we are responsible for preparing for and seeking regulatory approval, as well as performing and funding all future development and commercialization following such approval. POINT will be responsible for all manufacturing of PNT2002, subject to certain exceptions described in the license and collaboration agreement between Lantheus Two and POINT, dated November 11, 2022 (the “PNT2002 License Agreement”).
In April 2023, we announced with POINT that the FDA had granted Fast Track designation for PNT2002. Fast Track is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and address unmet needs.
On December 18, 2023, we announced positive topline results from SPLASH. SPLASH is designed to evaluate the efficacy and safety of PNT2002 in patients with mCRPC who have progressed following treatment with an androgen receptor pathway inhibitor (“ARPI”). The SPLASH trial met its primary endpoint, demonstrating a median radiographic progression-free survival (rPFS) per blinded independent central review of 9.5 months for patients treated with PNT2002, compared to 6.0 months for patients treated with ARPI in the control arm, a statistically significant 29% reduction in the risk of radiographic progression or death (hazard ratio (“HR”) 0.71; p=0.0088). At the time of the analysis, interim overall survival (“OS”) results were immature (46% of protocol-specified target OS events reached), and the HR was 1.11. We expect more mature overall survival data in 2024 prior to the potential submission of a New Drug Application (“NDA”).
PNT2002 demonstrated a favorable safety profile with grade ≥3 treatment-emergent adverse events (“TEAEs”) per Common Terminology Criteria for Adverse Events, serious TEAEs, and TEAEs leading to discontinuation occurring at lower rates in the PNT2002 arm than in the ARPI arm (30.1%, 17.1%, and 1.9% versus 36.9%, 23.1%, and 6.2%, respectively).
The open-label study randomized 412 patients with PSMA-expressing mCRPC who had progressed on ARPI therapy and either refused or were not eligible for chemotherapy, in a 2:1 randomization ratio. At the time of the analysis, 84.6% of patients who experienced progressive disease in the control arm subsequently crossed over to receive PNT2002. SPLASH was conducted across the United States, Canada, Europe, and the United Kingdom. Eighty percent of SPLASH patients resided in North America and approximately ten percent of all participants were Black or African American.
During 2023, we worked on establishing an Expanded Access Program, (“EAP”), for PNT2002. EAPs, which are also referred to as compassionate use programs, provide a potential pathway for patients with serious or life-threatening conditions to gain access to an investigational drug for treatment outside of a clinical trial. We expect to enroll the first patient in the EAP for PNT2002 during the first quarter of 2021, we completed2024.
PNT2003
With respect to PNT2003, POINT is responsible for curating all data, analysis and other information necessary for regulatory approval, and supporting us in the evaluationpreparation of our operatingregulatory filings. We are responsible for preparing for and reporting structure, includingseeking regulatory approval of all such applications, as well as performing and funding all future development and commercialization of PNT2003 following such approval. POINT will be responsible for all manufacturing of PNT2003, subject to certain exceptions described in the impact on our business of the acquisition of Progenicslicense and the sale of our Puerto Rico subsidiary, which resulted in a change in our operating segments to one reportable business segment.collaboration agreement between Lantheus Three and POINT, dated November 11, 2022 (the “PNT2003 License Agreement”).
On May 27, 2021,January 11, 2024, we announced that our ANDA for Lutetium Lu 177 Dotatate (177Lu-PNT2003) had been accepted for filing by the FDA. On January 26, 2024, we were sued in the District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the Company’s ANDA filing. Based on the most recent update to the FDA’s online paragraph IV database listings, we believe we are the first applicant to have filed a substantially complete ANDA for Lutetium Lu 177 Dotatate containing a Paragraph IV certification under the provisions of the Hatch-Waxman Act. As the first applicant, we believe we will be eligible for 180 days of generic marketing exclusivity in the U.S.
Under the Hatch-Waxman Act, any company submitting an ANDA must make certain certifications with respect to the patent status of the drug for which it is seeking approval. In the event that such applicant plans to challenge the validity or enforceability of an existing listed patent or asserts that the proposed product does not infringe an existing listed patent, it files a “Paragraph IV” certification. We filed a Paragraph IV certification in connection with PNT2003. In the case of ANDAs, the Hatch-Waxman Act provides for a potential 180-day period of generic exclusivity for the first company to submit an ANDA with a Paragraph IV certification. This filing triggers a regulatory process in which the FDA had approved PYLARIFY,is required to delay the final approval of subsequently filed ANDAs containing Paragraph IV certifications until 180 days after the first commercial marketing. When litigation is brought by the

patent holder in response to a Paragraph IV certification (like the Novartis entities did for our ANDA for PNT2003), the FDA generally may not approve the ANDA until the earlier of 30 months or a court decision finding the patent invalid, not infringed or unenforceable. The submission of our ANDA for PNT2003 could result in protracted and expensive patent litigation and the outcome of such litigation is uncertain.
Acquisition of Cerveau
On February 6, 2023, we announced that we acquired Cerveau. Cerveau holds the rights under a license agreement to develop and commercialize MK-6240, an investigational second-generation F 18-labeled PET imaging agent targeting prostate-specific membrane antigen (“PSMA”that targets Tau tangles in Alzheimer’s disease. Under the terms of our purchase agreement, we paid the stockholders of Cerveau (the “Selling Stockholders”). PYLARIFY an upfront payment of $35.0 million in February 2023 and an additional $10.0 million in May 2023 upon the successful completion of a technology transfer. The Selling Stockholders are also eligible to receive additional development and commercial milestone payments. Additionally, we will pay double-digit royalty payments for research revenue and commercial sales. Research revenue is derived from existing partnerships with pharmaceutical companies that use MK-6240 in clinical trials and includes milestone and dose-related payments. Pursuant to the terms of the stock purchase agreement for Cerveau, certain members of the Selling Stockholders will also provide transition and clinical development services for a product in our radiopharmaceutical oncology product category. We commercially launched PYLARIFY inprescribed time following the U.S. in June 2021.
During 2021, we announced that our subsidiary, EXINI, was granted 510(k) clearance byclosing of the FDA in the U.S. and a CE marking in Europe for aPROMISE. We commercially launched aPROMISE under the name PYLARIFY AI in the U.S. in November 2021.transaction.

Continued Growth of PYLARIFY
PYLARIFY is the leading radiopharmaceutical diagnostic agent indicated for PET imaging of PSMA-positive lesions in men with prostate cancer with suspected metastasis who are candidates for initial definitive therapy and in men with suspected recurrence based on elevated PSA levels. PYLARIFY works by binding to PSMA, a protein that is overexpressed on the surface of more than 90% of primary and metastatic prostate cancer cells. PYLARIFY works with PET/CT technology to produce a combined scan that enables the scan reader to detect and locate the disease.
According to the American Cancer Society, prostate cancer is the second most common cancer in American men - one in eight American men will be diagnosed with prostate cancer in their lifetimes and over 3.3 million American men are living with prostate cancer today. Based on estimates from third-party sources regarding the incidence of prostate cancer in men in the U.S., we believe the current market potential for PSMA PET imaging agents in the U.S. for 2024 could be about 445,000 scans, and the total addressable market by 2029 could be over 700,000 annual scans.
PYLARIFY is manufactured on a diverse, F 18 distributor supply network of PMFs, ensuring convenient and reliable supply. After being made on a cyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to a radiopharmacist who prepares and dispenses patient-specific doses of the final product. Because each PMF manufacturing PYLARIFY is deemed by the FDA to be a separate manufacturing site, each is separately approved by the FDA. As of December 31, 2023, we had activated 54 PMF manufacturing sites in our PMF network, up from 37 activated sites as of December 31, 2022. These additional sites provide geographic breadth, out-the-door time flexibility and added optionality within our existing PMF network. Overall, we have achieved broad national distribution of PYLARIFY with customers in 47 of 50 states, the District of Columbia and Puerto Rico.
In addition to our network of commercial PMFs, we also work with academic medical centers in the U.S. that have radioisotope-producing cyclotrons and that have expressed an interest in manufacturing PYLARIFY. For this initiative, we enter into a fee-for-service arrangement under which the academic medical center manufactures F 18 on its cyclotron and completes the manufacturing process for PYLARIFY. PYLARIFY can then be used by the academic medical center itself, and in some cases distributed to other customers under separate purchase agreements.
Our Healthcare Procedure Coding System (“HCPCS”) code, which enables streamlined billing, went into effect as of January 1, 2022. In addition, effective January 1, 2022, the Centers for Medicare and Medicaid Services (“CMS”) granted TPT Status in the hospital outpatient setting for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in that setting. TPT Status for PYLARIFY is expected to expire on December 31, 2024.
In July 2023, CMS proposed possible changes to its regulations covering payment for diagnostic radiopharmaceuticals. This included, for the first time since 2008, options for separate payment for diagnostics instead of the current packaged payment following expiration of TPT Status. We, along with numerous industry organizations, submitted comments to CMS. In completing its 2023 rulemaking for the 2024 payment calendar year, CMS recognized the challenges of patient access to diagnostic radiopharmaceuticals and requested feedback on various payment alternatives that could provide separate reimbursement for these items, but the agency did not adopt any of these proposals in the final rule, while stating that it would continue to evaluate this issue in subsequent rulemaking. We plan to submit additional comments to CMS in connection with its 2024 rulemaking for the 2025 payment calendar year.
Our continued growth of PYLARIFY will depend on our ability to clinically and commercially differentiate PYLARIFY from other products on the market and to maintain PYLARIFY as the leading PSMA PET imaging agent in a competitive marketplace. PYLARIFY’s current competition is primarily two Gallium-68 (“Ga-68”)-based PSMA imaging agents, a fluorine-18-based PSMA

imaging agent, and other non-PSMA-based imaging agents commonly referred to as conventional imaging. Continued growth and revenue contribution from PYLARIFY will also depend on our ability to differentiate PYLARIFY in light of the potential loss of TPT Status, including through flexible and dependable access to PYLARIFY nationally, a best in class customer experience and through long-term strategic contracts.
We actively pursue patents in connection with PYLARIFY, both in the U.S. and internationally. In the U.S. for PYLARIFY, we have five Orange Book-listed patents, including composition of matter patents, the last of which expires in 2037. Outside of the U.S., we have, and are currently pursuing, additional PYLARIFY patents to obtain similar patent protection as in the U.S.

Anticipated Continued Growth of DEFINITY and Expansion of Our Ultrasound Microbubble Franchise
DEFINITY is the leading ultrasound enhancing agent based on revenue and usage in the U.S., and is indicated for use in patients with suboptimal echocardiograms.echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border. Numerous patient conditions can decrease the quality of images of the left ventricle, the primary pumping chamber of the heart. The term DEFINITY includes its activated and non-activated forms.forms and the two formulations it is commercially available in; one that requires refrigerated storage and one that we have branded as DEFINITY RT that may be stored at room temperature.
DEFINITY is a clear, colorless, sterile liquid that, requires refrigerated storage, and which, upon activation in a VIALMIX apparatus, aor VIALMIX RFID, medical devicedevices specifically designed for DEFINITY, becomes a homogenous, opaque, milky white injectable suspension of perflutren-containing lipid microspheres. After activation and intravenous injection, DEFINITY opacifies the left ventricular chamber and improves the delineation of the left ventricular endocardial border, or innermost layer of tissue that lines the chamber of the left ventricle. Better visualization of the left ventricle allows clinicians to make more informed decisions about disease status.

Based on estimates from third party sources, we believe there were approximately 2529 to 3230 million echocardiograms performed in the U.S. in 20202022 (the latest time period for which full year data is available and which also included the estimated impacts of COVID-19 on procedure volumes)available). Assuming that between 20% and 30% of echocardiograms produce suboptimal images, as stated in the clinical literature, we estimate that approximately 56 to 109 million echocardiograms in 20202022 produced suboptimal images.
Since its launch in 2001, DEFINITY has been used in imaging procedures in more than 18.025 million studies throughout the world. We estimate that, as of December 31, 2023, DEFINITY had over 80% share of the U.S. segment for ultrasound enhancing agents in echocardiography procedures as of December 2021.procedures. DEFINITY currently competes with Optison, a GE Healthcare product, Lumason, a Bracco Diagnostics Inc. (“Bracco”) product,two other FDA-approved ultrasound enhancing agents, as well as echocardiography without the use of ultrasound enhancing agents and non-echocardiography imaging modalities. DEFINITY Optison and Lumasonthe other FDA-approved ultrasound enhancing agents all carry an FDA-required boxed warning, which has been modified over time, to notify physicians and patients about potentially serious safety concerns or risks posed by the products. See Part I, Item 1A. “Risk Factors-Ultrasound enhancing agents may cause side effects which could limit our ability to sell DEFINITY.”
As we continue to pursue expanding our microbubble franchise, our activities include:
Patents - We continue to actively pursue additional patents in connection with DEFINITY and DEFINITY RT, both in the U.S. and internationally. In the U.S. for DEFINITY, we have foursix Orange Book-listed method of usemethod-of-use patents, one of which expires in 2035 and threefive of which expire in 2037, as well as additional manufacturing patents that are not Orange Book-listed expiring in 2023 and 2037. In the U.S. for DEFINITY RT, we have fiveeight Orange Book-listed patents, including atwo composition of matter patentpatents which expiresexpire in 2035. Outside of the U.S., we are currently pursuing additional DEFINITY and DEFINITY RT patents to obtain similar patent protection as in the U.S. The Orange Book-listed patents include a patent on the use of VIALMIX RFID (see below), which expires in 2037; we have submitted additional VIALMIX RFID patent applications in major markets throughout the world.
Hatch-Waxman Act - Even though our longest duration Orange Book-listed DEFINITY patent extends until March 2037, because our Orange Book-listed composition of matter patent expired in June 2019, we may face generic DEFINITY challengerschallenges in the near to intermediate term. Under the Hatch-Waxman Act, the FDA can approve Abbreviated New Drug Applications (“ANDAs”) for generic versions of drugs if the ANDA applicant demonstrates, among other things, that (i) its generic candidate is the same as the innovator product by establishing bioequivalence and providing relevant chemistry, manufacturing and product data, and (ii) either the marketing of that generic candidate does not infringe the Orange Book-listed patent(s) or the Orange Book-listed patent(s) is invalid. Similarly, the FDA can approve a Section 505(b)(2) NDA from an applicant that relies on some of the information required for marketing approval from studies which the applicant does not own or have a legal right of reference. With respect to the Orange Book-listed patent(s) covering an innovator product, the ANDA or Section 505(b)(2) applicant (if relying on studies related to the innovator product) (each, the “Applicant”) must give a notice (a “Notice”) to the innovator of its certification that its generic candidate will not infringe the innovator’s Orange Book-listed patent(s) or that the Orange Book-listed patent(s) is invalid. The innovator can then file suit against the Applicant within 45 days of receiving the Notice, and FDA approval to commercialize the generic candidate will be stayed (that is, delayed) for up to 30 months (measured from the date on which a Notice is received) while the patent dispute between the innovator and the Applicant is resolved in court. The 30-month stay could potentially expire sooner if the courts determine that no infringement had occurred or that the challenged Orange Book-listed patent is invalid or if the parties otherwise settle their dispute.See “Intellectual Property – Patents” below.
As noted above, DEFINITY is activated through the use of the date of filing of this Annual Report on Form 10-K, we have not received any Notice from an Applicant. If we were to (i) receive any such Notice in the future, (ii) bring a patent infringement suit against the Applicant within 45 days of receiving that Notice,medical devices branded as VIALMIX and (iii) successfully obtain the full 30-month stay, then the Applicant would be precluded from commercializing a generic version of DEFINITY prior to the expiration of that 30-month stay period and, potentially, thereafter, depending on how the patent dispute is resolved. Solely by way of example and not based on any knowledge we currently have, if we received a Notice from an Applicant in March 2022 and the full 30-month stay were obtained, then the Applicant would be precluded from commercialization until at least September 2024. If we received a Notice some number of months in the future and the full 30-month stay were obtained, the commercialization date would roll forward in the future by the same number of months. In the event a 505(b)(2) applicant does not rely on studies related to the innovator product, the 30-month stay would not apply, but additional clinical studies may be required.
DEFINITY RT - DEFINITY RT became commercially available in the fourth quarter of 2021. A modified formulation of DEFINITY that allows both storage and shipment at room temperature, DEFINITY RT provides clinicians an additional choice and allows for greater utility of this formulation in broader clinical settings. Given its physical characteristics, we believe DEFINITY RT is also well-suited for inclusion in kits requiring microbubbles for other indications and applications (including in kits developed by third parties of the type described in the paragraph entitled Microbubble Franchise below).

TechneLite
TechneLite is a self-contained system or generator of Tc-99m, a radioactive isotope with a six hour half-life, used by radiopharmacies to prepare various nuclear imaging agents. Tc-99m results from the radioactive decay of Mo-99, itself a radioisotope with a 66-hour half-life producedsourced in our supply chain in nuclear research reactors around the worldlocated in Belgium, South Africa and Australia from enriched uranium. The TechneLite generator is a little larger than a coffee can in size, and the self-contained system that houses a vertical glass column at its core that contains Mo-99.Mo-99, which degrades to Tc-99m. During our manufacturing process, Mo-99 is added to the column within the generator where it is adsorbed onto alumina powder. The column is sterilized, enclosed in a lead shield and further sealed in a cylindrical plastic container, which is then immediately shipped to our radiopharmacy customers. Because of the short half-lives of Mo-99 and Tc-99m, radiopharmacies typically purchase TechneLite generators on a weekly basis pursuant to standing orders.
The Tc-99m produced by our TechneLite generator is the medical radioisotope that can be attached to a number of imaging agents, including our own NEUROLITE and CardioliteCARDIOLITE products, during the radiolabeling process. To radiolabel a Tc-99m-based radiopharmaceutical, a vial of sterile saline and a vacuum vial are each affixed to the top of a TechneLite generator. The sterile saline is pulled through the generator where it attracts Tc-99m resulting from the radioactive decay of Mo-99 within the generator column. The Tc-99m-containing radioactive saline is then pulled into thea vacuum vial and subsequently combined by a radiopharmacist with the applicable imaging agent, andwhich allows the preparation of individual patient-specific radiolabeled imaging agent doses are then prepared.doses. When administered, the imaging agent binds to specific tissues or organs for a period of time, enabling the Tc-99m to illuminate the functional health of the imaged tissues or organs in a diagnostic image. Our ability to produce and market TechneLite is highly dependent on our supply of Mo-99. See “Raw Materials and Supply Relationships—Molybdenum-99” below.
TechneLite is currently marketed primarily in North America,the U.S., Canada, Central America and South America, largely to radiopharmacies that prepare unit doses of radiopharmaceutical imaging agents and ship these preparations directly to hospitals for administration to patients. In the U.S., we have supply contracts with large radiopharmacy groups, including Cardinal Health (“Cardinal”), PharmaLogic Holdings Corp (“PharmaLogic”), Cardinal Health (“Cardinal”), RLS (USA) Inc. (previously GE Healthcare) (“RLS”) and United Pharmacy Partners (“UPPI”). We also supply generators on a purchase order basis to other customers. We estimate that TechneLite had approximately one third of the U.S. generator market as of December 31, 2021,2023, competing primarily with Tc-99m-based generators produced by Curium and NorthStar Medical Radioisotopes, LLC (“Northstar”). Outside of the U.S., we sell generators through supply agreements with radiopharmacy chains, through distributors or to separate customers.
The Mo-99 used in our TechneLite generators can be produced using targets made of either highly-enriched uranium (“HEU”) or low-enriched uranium (“LEU”). LEU consists of uranium that contains less than 20% of the uranium-235 isotope. HEU is considered weapons grade material, with 20% or more of uranium-235. The American Medical Isotopes Production Act of 2012 encourages the domestic production of LEU Mo-99 and provides for the eventual prohibition of the export of HEU from the U.S. Although Medicare generally does not provide separate payment to hospitals for the use of diagnostic radiopharmaceuticals administered in an outpatient setting, since 2013, the Centers for Medicare and Medicaid Services (“CMS”), the federal agency responsible for administering the Medicare program, has provided an add-on payment of $10 under the hospital outpatient prospective payment system for every Tc-99m diagnostic dose produced from non-HEU sourced Mo-99, to cover the marginal cost for radioisotopes produced from non-HEU sources. Our LEU TechneLite generator satisfies the reimbursement requirements under the applicable CMS rules.

Curium.
We believe that our substantial capital investments in our highly automated TechneLite production line which we have made over the years, and our extensive experience in complying with the stringent regulatory requirements for the handling of nuclear materials, create significant and sustainable competitive advantages for us in generator manufacturing and distribution. Given our significant know-how and trade secrets associated with the methods of manufacturing and assembling the TechneLite generator, we believe we have a substantial amount of valuable and defensible proprietary intellectual property associated with the product. In addition, TechneLite has patent protection in the U.S. and various foreign countries on certain component technology currently expiring inuntil 2029, and we are pursuing additional patent protection in the U.S. and world-wide on other component technology that, if granted, would expire in 2040.

PYLARIFY Approval and Commercial Launch
PYLARIFY is a radioactive diagnostic agent indicated for PET imaging of PSMA-positive lesions in men with prostate cancer with suspected metastasis who are candidates for initial definitive therapy and in men with suspected recurrence based on elevated PSA levels. PYLARIFY works by binding to PSMA, a protein that is overexpressed on the surface of more than 90% of primary and metastatic prostate cancer cells. PYLARIFY works with PET/CT technology to produce a combined PET/CT scan that enables the reader of the PET/CT scan to detect and locate the disease.
According to the American Cancer Society, prostate cancer is the second most common cancer in American men - one in eight American men will be diagnosed with prostate cancer in their lifetimes and over 3.1 million American men are living with prostate cancer today. Based on estimates from third party sources regarding the incidence of prostate cancer in men in the U.S., we believe the potential market size for PSMA PET imaging agents could be up to 220,000 annual scans, comprised of 90,000 scans for patients with intermediate, unfavorable or high/very high risk of suspected metastases of prostate cancer and 130,000 scans for patients with suspected recurrence of prostate cancer. Because we are in the process of launching this imaging agent, we can give no assurance as to how clinical practice may evolve or what our ultimate market penetration may be.
The approval of PYLARIFY was based on data from two Company-sponsored pivotal studies (“OSPREY” and “CONDOR”) designed to establish the safety and diagnostic performance of PYLARIFY across the prostate cancer disease continuum. Results from OSPREY (Cohort A) demonstrated improvement in specificity and positive predictive value of PYLARIFY PET imaging over conventional imaging in men at risk for metastatic prostate cancer prior to initial definitive therapy. CONDOR studied men with biochemical recurrent prostate cancer. In patients with biochemical recurrent prostate cancer and non-informative baseline imaging, PYLARIFY demonstrated high correct localization and detection rates, including in patients with early recurrent disease with low but rising PSA blood levels (median PSA 0.8 ng/mL).
Upon commercial launch in June 2021, PYLARIFY was immediately available in select parts of the U.S. Over the course of the remainder of 2021, PYLARIFY availability expanded into additional regions and is now broadly available nationwide. We continue to expand our geographic coverage, customer contracting and market access coverage to serve our customers and the U.S. prostate cancer community.
The commercial launch of PYLARIFY is complex and expensive. During 2021, we hired additional employees to assist us with the commercialization of PYLARIFY, including in sales, marketing, reimbursement, quality and medical affairs. To manufacture PYLARIFY, we assembled and are qualifying a nationwide network of PMFs with radioisotope-producing cyclotrons that make F 18, which has a 110-minute half-life, so PYLARIFY is manufactured and distributed rapidly to end-users. After being made on a cyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to a radiopharmacist who prepares and dispenses patient-specific doses of the final product. Because each of the PMFs manufacturing these products is deemed by the FDA to be a separate manufacturing site, each has to be approved by the FDA. Although PYLARIFY is now broadly available nationwide and we continue to qualify additional PMFs, we can give no assurance that the FDA will continue to approve PMFs in accordance with our planned roll-out schedule. If FDA approval of manufacturing sites is delayed or withdrawn, our future business, results of operations, financial condition and cash flows could be adversely affected.
In addition to our network of PMFs, we have also been working with academic medical centers in the U.S. that have radioisotope-producing cyclotrons and which have expressed an interest in manufacturing PYLARIFY. Under this initiative, we would enter into a fee-for-service arrangement under which the academic medical center’s PMF would manufacture and supply batches of PYLARIFY, and its radiopharmacy would prepare patient-ready unit doses, in each case for and on behalf of us. We would then sell

Table of Contents

those unit doses to the academic medical center’s hospitals and clinics, and in some instances, to additional customers in the academic medical center’s geographic area, in each case, under separate purchase agreements. The academic medical center’s PMF’s ability to manufacture and supply batches of PYLARIFY will be subject to FDA approval, and we can give no assurance that the FDA will approve such PMFs in accordance with our planned roll-out schedule.
Our commercial launch also required us to obtain adequate coding, coverage and payment for PYLARIFY, including not only coverage from Medicare, Medicaid and other government payors, as well as private payors, but also appropriate payment levels to adequately cover our customers’ costs of using PYLARIFY in PET/CT imaging procedures. We received notification that our Healthcare Procedure Coding System (“HCPCS”) code, which enables streamlined billing, went into effect as of January 1, 2022. In addition, effective January 1, 2022, CMS granted Transitional Pass-Through Payment Status in the hospital outpatient setting (“TPT Status”) for PYLARIFY, enabling traditional Medicare to provide an incremental payment to our customers for PET/CT scans performed with PYLARIFY in that setting. TPT Status for PYLARIFY is expected to expire December 31, 2024. After TPT Status expires, under current Medicare rules, PYLARIFY, similar to other diagnostic radiopharmaceuticals, would not be separately reimbursed in the hospital outpatient setting but rather would be included as part of the facility fee a hospital otherwise receives for a PET/CT imaging procedure, and the facility fee does not always cover the cost of a drug used in the procedure. We can give no assurance that any CMS reimbursement in the hospital outpatient setting that follows the expiration of TPT Status will be adequate to cover the cost of PYLARIFY used in a PET/CT imaging procedure.
We actively pursue patents in connection with PYLARIFY, both in the U.S. and internationally. In the U.S. for PYLARIFY, we have four Orange Book-listed patents, including composition of matter patents, which expire in 2030 and 2037. Outside of the U.S., we are currently pursuing additional PYLARIFY patents to obtain similar patent protection as in the U.S.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with PYLARIFY and see Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Comparison of the Periods Ended December 31, 2021 and 2020 and Comparison of the Periods Ended December 31, 2020 and 2019 - Revenues” for further information on total revenue contributed by PYLARIFY since its approval.TechneLite.

PYLARIFY AI which we also refer to as aPROMISE, is an artificial intelligence medical device software that is designed to allow healthcare professionals and researchers to perform standardized quantitative assessment of PSMA PET/CT images in prostate cancer, including those images obtained by using PYLARIFY. PYLARIFY AI has demonstrated improved consistency, accuracy and efficiency in quantitative assessment of PSMA PET/CT. The technology automatically analyzes the PET/CT image to segment anatomical regions, including 51 bones and 12 soft tissue organs. This image segmentation enables automated localization, detection and quantification of potential PSMA-avid lesions in the PET/CT image, which is incorporated into a standardized report for physicians. PYLARIFY AI can be deployed either as a secure web cloud application or within the secure firewall of the institution on a local server. Once deployed, the adaptive application can be integrated into an institution’s existing clinical workflow, delivering a unique combination of clinical utility and technical flexibility. We believe that PYLARIFY AI when used with PYLARIFY will provide us an important competitive advantage in what we expect will be a highly competitive PET PSMA diagnostic imaging agent market, although we can give no assurances to that effect. Our subsidiary, EXINI, was granted 510(k) clearance by the FDA in the U.S. and received a CE marking in Europe for aPROMISE. We commercially launched aPROMISE under the name PYLARIFY AI in the U.S. in November 2021.2021 and the FDA granted us an additional 510(k) clearance during the second quarter of 2022.

Backlog
Our backlog consists of orders for which a delivery schedule within the next twelve months has been specified. Orders included in backlog may be canceled or rescheduled by customers at any time with the exception of TechneLite orders. For TechneLite, customers must provide us with four weeks advanced notice to cancel an order. We do not believe that our backlog at any particular time is meaningful because it has historically been immaterial relative to our consolidated revenues and is not necessarily indicative of future revenues for any given period.
Competition
We believe that our key product characteristics, such as proven efficacy, reliability and safety, coupled with our core competencies, such as our efficient manufacturing processes, our established distribution network, our experienced field sales organization and our customer service focus, are important factors that distinguish us from our competitors.
The markets for our products are highly competitive and continually evolving. Our principal competitors for our current commercial products and leading clinical development candidates include large, global companies that are more diversified than we are and that have substantial financial, manufacturing, sales and marketing, distribution and other resources.
For PYLARIFY, our principal competitors are currently Telix Pharmaceuticals Limited, Novartis AG, and Blue Earth Diagonstics Ltd. (“Blue Earth”), a subsidiary of Bracco Diagnostics Inc. (“Bracco”).
For DEFINITY, our competitors currently include GE Healthcare and Bracco.

modalities and products, or bundle the sale of a portfolio of products, to the detriment of our specific products. Our current or future products could be rendered obsolete or uneconomical as a result of these activities.
Further, the radiopharmaceutical and biopharmaceutical industry continues to evolve strategically, with several market participants either recently sold or for sale.sold. In addition, the supply-demand dynamics of the industry are complex because of large market positions of some participants, legacy businesses, government subsidies (in particular, relating to the manufacture of radioisotopes), government reimbursement policies, such as TPT Status, and group purchasing arrangements. We cannot predict what impact new owners and new operators may have on the strategic decision-making of our competitors, customers and suppliers.
Raw Materials and Supply Relationships
We rely on certain raw materials and supplies to produce our products. Due to the specialized nature of our products and the limited, and sometimes intermittent, supply of raw materials available in the market, we have established relationships with several key suppliers. For the year ended December 31, 2021,2023, our largest suppliers of raw materials and supplies were Institute for Radioelements (“IRE”), the Australian Nuclear Science and Technology Organisation (“ANSTO”) and NTP Radioisotopes (“NTP”), which, in the aggregate, accounted for approximately 21%9.3% of our total purchases.

Molybdenum-99
Our TechneLite, CardioliteCARDIOLITE and NEUROLITE products all rely on Mo-99, the radioisotope which is produced by bombarding uranium with neutrons in research reactors. With a 66-hour half-life, Mo-99 decays into, among other things, Tc-99m, another radioisotope with a half-life of six hours. Tc-99m is the isotope that is attached to radiopharmaceuticals, including our own NEUROLITE and Cardiolite,CARDIOLITE, during the labeling process and is the most common radioisotope used for medical diagnostic imaging purposes.
We currently purchase finished Mo-99 from three of the four main processing sites in the world, namely IRE in Belgium, NTP in South Africa and ANSTO in Australia. These processing sites provide us Mo-99 from five of the six main Mo-99-producing reactors in the world, namely BR2 in Belgium, LVR-15 in the Czech Republic, HFR in The Netherlands, SAFARI in South Africa and OPAL in Australia.
Our agreement with IRE (the “IRE Agreement”) contains minimum percentage volume requirements and unit pricing. The IRE Agreement also requires IRE to provide certain favorable allocations of Mo-99 during periods of supply shortage or failure. The IRE Agreement also provides for an increased supply of Mo-99 derived from LEU targets upon IRE’s completion of its ongoing conversion program to modify its facilities and processes in accordance with Belgian nuclear security commitments. The IRE Agreement allows for termination upon the occurrence of certain events, including failure by IRE to provide our required amount of Mo-99, material breach of any provision by either party, bankruptcy by either party or force majeure events. The IRE Agreement expires on December 31, 2023,2024, and automatically renews on an annual basis thereafter, subject to prior notice of non-renewal by either party.
Our agreement with NTP (the “NTP Agreement”), with NTP acting for itself and on behalf of its subcontractor ANSTO, specifies our percentage purchase requirements and unit pricing, and provides for the supply of Mo-99 derived from LEU targets from NTP and ANSTO.Mo-99. The NTP Agreement allows for termination upon the occurrence of certain events, including failure by NTP to provide our required amount of Mo-99, material breach of any provision by either party, bankruptcy by either party or force majeure events. The NTP Agreement expires on MarchDecember 31, 2022, and2024.
Although we are actively negotiating an extension.
Despite ourhave a globally diverse Mo-99 suppliers,supply with IRE in Belgium, NTP in South Africa, and ANSTO in Australia, we still face supplier and logistical challenges in our Mo-99 supply chain. The NTP processing facility had periodicWhen one supplier experiences outages, in 2017, 2018 and 2019. When NTP was not producing, we reliedgenerally rely on Mo-99 supply from both IRE and ANSTOthe other suppliers to limit the impact of the NTP outages. In 2019 and 2020, ANSTO experienced multiple facility issues that resulted in ANSTO outages and volume limitations, during which timeWe believe we relied on IRE and NTP to limit the impact of those outages and limitations. Because of the COVID-19 pandemic, we experienced challenges receiving regularly scheduled orders of Mo-99 from our global suppliers, particularly in the second quarter of 2020. We continue toeffectively manage these various supply chain challenges. Dependingchallenges, but depending on reactor and processor schedules and operations, at times we have not been able to fill some or all of the demand for our TechneLite generators on certain manufacturing days. A prolonged disruption of service from one of our three Mo-99 processing sites or one of their main Mo-99-producing reactors could have a substantial negative effect on our business, results of operations, financial condition and cash flows.
To augment our current supply of Mo-99, we entered into a strategic arrangement with SHINE Medical Technologies LLC (“SHINE”) for the future supply of Mo-99. Under the terms of the supply agreement, entered into in November 2014, SHINE will provide Mo-99 produced using its proprietary LEU-solution technology for use in our TechneLite generators once SHINE’s facility becomes operational and receives all necessary regulatory approvals, which SHINE now estimates will occur in 2023. The term of this arrangement provides for three years of supply of Mo-99. However, we cannot assure you that our arrangement with SHINE will

result in commercial quantities of Mo-99 for our business, or that SHINE together with our current suppliers will be able to deliver a sufficient quantity of Mo-99 to meet our needs.
Xenon
Xenon is a by-product of the Mo-99 production process. Under a strategic agreement entered into in 2021, we receive from IRE bulk unprocessed Xenon, which we process and finish for our customers at our North Billerica, Massachusetts manufacturing facility. That contract runs through December 31, 2023,2025, with auto-renewal provisions and is terminable upon notice of non-renewal. Until we can qualify an additional source of bulk unprocessed Xenon, we will rely on IRE as a sole source provider.
Iodine 131
Iodine 131 is also a by-product of the Mo-99 production process, and it is the active radioisotope ingredient in both AZEDRA and 1095. We receive Iodine 131 from IRE in Belgium and we are in the process of securing a secondary source. We use Iodine 131 at our Somerset facility to manufacture and produce AZEDRA. We also rely on Center for Probe Development and Commercialization (“CPDC”) in Canada for our clinical supply requirements for 1095. CPDC sources Iodine 131 from IRE in Belgium and NTP in South Africa.
Other Materials
We have additional supply arrangements for active pharmaceutical ingredients, excipients, packaging materials and other materials and components, none of which are exclusive, but a number of which are sole source, and all of which we currently believe are either in good standing or replaceable without any material disruption to our business.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with our raw materials and supply arrangements.
Manufacturing
We maintain manufacturing operations at our North Billerica, Massachusetts facility. WeThe commercial manufacture TechneLiteof PYLARIFY required us to create a field-based network of specialized PMFs with radioisotope-producing cyclotrons. The radioisotope used in PYLARIFY is F 18, which has a 110 minute half-life, requiring that this agent be manufactured and distributed rapidly to end-users. After being made on a highly automated production line, Thalliumcyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and Galliumtransferred to a radiopharmacist who prepares and certain radiochemicals using our cyclotron technology, and we process and finish Xenon on a hot cell line. We also operate adispenses patient-specific doses from the final product. Because each of the PMFs manufacturing facility at Somerset, NJ, using a hot cell line for AZEDRA. During 2021, we increased the manufacturing staff at our Somerset facility to help maintain an adequate supply of AZEDRA. We also began constructing an additional manufacturing suite at Somerset which, if approvedPYLARIFY is deemed by the FDA could provide redundancy for AZEDRAto be a separate manufacturing as well as increased overall future capacity for 1095, if approved by thesite, each requires separate FDA or other iodine-based products.approval.
We have constructed a specialized in-house manufacturing facility at our North Billerica campus for purposes of producing the formulation of DEFINITY that requires refrigerated storage and, potentially, other sterile vial products. On February 22, 2022, we received FDA

approval of our sNDA, authorizing commercial manufacturing of DEFINITY at our new facility. DEFINITY manufactured at this facility became commercially available on February 23, 2022. We believe this investment will allow us to better manage DEFINITY manufacturingprovides supply chain redundancy, improved flexibility and inventory, reduce ourreduced costs in a potentially more price competitive environment,environment.
We also manufacture TechneLite on an automated production line and provide us with supply chain redundancy.we process and finish Xenon on a hot cell line at our North Billerica, Massachusetts facility.
We manufacture, finish and distribute our radiopharmaceutical products on a just-in-time basis, and supply our customers with these products either by next day delivery services or by either ground or air custom logistics. We believe that our substantial capital investments in our highly automated generator production line our cyclotrons and our other manufacturing assets, which we have made over the years, and our extensive experience in complying with the stringent regulatory requirements for the handling of nuclear materials and operations in a highly regulated environment, create significant and sustainable competitive advantages for us.
In addition to our in-house manufacturing capabilities, a substantial portion of our products are manufactured by third party contract manufacturing organizations, and in certain instances, we rely on them for sole source manufacturing. To ensure the quality of the products that are manufactured by third parties, the key raw materials used in those products are first sent to our North Billerica, Massachusetts facility, where we test them prior to the third party manufacturing of the final product. AfterFor many of our products, after the final products are manufactured, they are sent back to us for final quality control testing, and then we ship them to our customers. We have expertise in the design, development and validation of complex manufacturing systems and processes, and our strong execution and quality control culture supports the just-in-time manufacturing model at our manufacturing facilities.

The commercial manufacture of PYLARIFY required us to create a field-based network of specialized PMFs with radioisotope-producing cyclotrons. The radioisotope used in PYLARIFY is F 18, which has a 110 minute half-life, requiring that this agent be manufactured and distributed rapidly to end-users. After being made on a cyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to a radiopharmacist who prepares and dispenses patient-specific doses from the final product. Because each of the PMFs manufacturing PYLARIFY is deemed by the FDA to be a separate manufacturing site, each requires separate FDA approval, and we can give no assurance that the FDA will continue to approve PMFs in accordance with our planned roll-out schedule for PYLARIFY, particularly given ongoing challenges of the COVID-19 pandemic. Flurpiridaz F 18, if approved by the FDA, will have a manufacturing and PMF approval process similar to PYLARIFY.
Manufacturing and Supply Arrangements
We currently have the following technology transfer and manufacturing and supply agreements in place for some of our major products:
PYLARIFY—We have entered into commercial supply agreements with different PMF networks. Our agreements with our PMF networks allow for the termination upon the occurrence of specified events, including material breach or bankruptcy by either party, and have various termination dates generally terminating between 2025 and 2030 and are subject to renewal provisions.
DEFINITY, CardioliteCARDIOLITE and NEUROLITE—In February 2022, we entered into a new Manufacturing and Supply Agreement with JHS, for the manufacture of DEFINITY, Cardiolite,CARDIOLITE, NEUROLITE and evacuation vials.vials, the latter being an ancillary component for our TechneLite generators. The new agreement which superseded all of our prior agreements with JHS for those products, expires on December 31, 2027, and can be renewed upon mutual consent. The agreement allows for termination upon the occurrence of certain events such as a material breach or default by either party, or bankruptcy by either party. The agreement also requires us to order from JHS a specified minimum percentage of our requirements for DEFINITY and fixed quantities of CardioliteCARDIOLITE and NEUROLITE each year during the contract term. Based on our current projections, we believe that we will have sufficient supply of DEFINITY from JHS and our in-house manufacturing facility and sufficient supply of Cardiolite and NEUROLITE products from JHS to meet expected demand.
PYLARIFY—The commercial manufacture of PYLARIFY required us to create a field-based network of specialized PMFs with radioisotope-producing cyclotrons. In preparation for our commercial launch, we entered into commercial supply agreements with different radiopharmacy networks. Under our supply agreements, the PMF manufactures the radioisotope F 18 on a cyclotron, and then combines the F 18 with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to the PMF’s radiopharmacist who prepares and dispenses patient-specific doses from the final product. Our agreements with our PMF networks allow for the termination upon the occurrence of specified events, including material breach or bankruptcy by either party, and have various termination dates generally terminating in 2025 and subject to renewal provisions.

Intellectual Property
Patents, trademarks and other intellectual property rights, both in the U.S. and foreign countries, are very important to our business. We also rely on trade secrets, manufacturing know-how, technological innovations, licensing agreements and confidentiality agreements to maintain and improve our competitive position. We review third party proprietary rights, including patents and patent applications, as available, in an effort to develop an effective intellectual property strategy, avoid infringement of third party proprietary rights, identify licensing opportunities and monitor the intellectual property owned by others. Our ability to enforce, defend and protect our intellectual property rights may be limited in certain countries outside the U.S., which could make it easier for competitors to capture market position in those countries by utilizing technologies that are similar to those developed or licensed by us. Competitors also may harm our sales by designing products that mirror the capabilities of our products or technology without infringing our intellectual property rights. If we do not obtain sufficient protection for our intellectual property, or if we are unable to effectively enforce or defend our intellectual property rights or our freedom to operate, our competitiveness could be impaired, which would limit our growth and future revenue. If we elect to enforce our intellectual property rights, or are required to defend our rights, we could incur significant litigation expense.
Trademarks, Service Marks and Trade Names
We own various trademarks, service marks and trade names, including, among others, AZEDRA, AZEDRA Service Connection, Cardiolite,PYLARIFY, DEFINITY DEFINITY RT, EXINI,and Find Fight and Follow, Find > Fight > Follow, Lantheus, Lantheus Medical Imaging, LUMINITY, Molecular Insight, NEUROLITE, Progenics, Progenics Pharmaceuticals, PYLARIFY, PYLARIFY AI, TechneLite, VIALMIX and VIALMIX RFID.Follow. We have generally registered these trademarks, as well as others, in the U.S. and/or numerous foreign jurisdictions.

Patents
We actively seek to protect the proprietary technology that we consider important to our business, including chemical species, compositions and formulations, their methods of use and processes for their manufacture, as new intellectual property is developed. In addition to seeking patent protection in the U.S., we file patent applications in numerous foreign countries in order to further protect the inventions that we consider important to the development of our international business. We also rely upon trade secrets and contracts to protect our proprietary information.
We have patent protection on certain of our commercial products and on all of our clinical development candidates. We typically seek patent protection in major markets around the world, including, among others, the U.S., Canada, Western Europe, Asia, Central America and South America. All patent terms described below are presented without giving effect to any applicable patent term adjustments or regulatory extensions.
PYLARIFY - We actively pursue patents in connection with PYLARIFY, both in the U.S. and internationally. In the U.S. for PYLARIFY, we have five Orange Book-listed patents, including composition of matter patents, the last of which expire in 2037. Outside of the U.S., we have, and are currently pursuing, additional PYLARIFY patents to obtain similar patent protection as in the U.S.
DEFINITY - We continue to actively pursue additional patents in connection with DEFINITY and DEFINITY RT, both in the U.S. and internationally. In the U.S. for DEFINITY, we have foursix Orange Book-listed method of usemethod-of-use patents, one of which expires in 2035 and threefive of which expire in 2037, as well as additional manufacturing patents that are not Orange Book-listed expiring in 2023 and 2037. In the U.S. for DEFINITY RT, we have fiveeight Orange Book-listed patents, including atwo composition of matter patentpatents which expiresexpire in 2035. Outside of the U.S., we are currently pursuing additional DEFINITY and DEFINITY RT patents to obtain similar patent protection as in the U.S. The Orange Book-listed patents include a patent on the use of VIALMIX RFID which expires in 2037; additional VIALMIX RFID patent applications have been submitted in major markets throughout the world.
Even though our longest duration Orange Book-listed DEFINITY patent extends until March 2037, because our Orange Book-listed composition of matter patent expired in June 2019, we may face generic DEFINITY challengers in the near to intermediate term. Under the Hatch-Waxman Act, the FDA can approve Abbreviated New Drug Applications (“ANDAs”)ANDAs for generic versions of drugs if the ANDA applicant demonstrates, among other things, that (i) its generic candidate is the same as the innovator product by establishing bioequivalence and providing relevant chemistry, manufacturing and product data, and (ii) either the marketing of that generic candidate does not infringe the Orange Book-listed patent(s) or the Orange Book-listed patent(s) is invalid. Similarly, the FDA can approve a Section 505(b)(2) NDA from an applicant that relies on some of the information required for marketing approval to come from studies which the applicant does not own or have a legal right of reference. With respect to the Orange Book-listed patent(s) covering an innovator product, the ANDA applicant or the Section 505(b)(2) applicant (if relying on studies related to the innovator product) (together, the “Applicant”) must give a notice (a “Notice”) to the innovator of its certification that its generic candidate will not infringe the innovator’s Orange Book-listed patent(s) or that the Orange Book-listed patent(s) is invalid. The innovator can then file suit against the Applicant within 45 days of receiving the Notice, and FDA approval to commercialize the generic candidate will be stayed (that is, delayed) for up to 30 months (measured from the date on which a Notice is received) while the patent dispute between the innovator and the Applicant is resolved in court. The 30-month stay could potentially expire sooner if the courts determine that no infringement had occurred or that the challenged Orange Book-listed patent is invalid or if the parties otherwise settle their dispute. WeSubmission of an ANDA with a Paragraph IV certification can give no assurance that we would have grounds to file aresult in protracted and expensive patent infringement suit, that we would obtain the full 30 month stay, that we would be successful on the merits asserting that an Applicant infringes our Orange Book-listed patent, or that we would be successful defending the validity or enforceability of our Orange Book-listed patent in court or in a USPTO adversarial proceeding.litigation.
As of the date of filing of this Annual Report on Form 10-K, we have not received any Notice from an Applicant. If we were to (i) receive any such Notice in the future, (ii) bring a patent infringement suit against the Applicant within 45 days of receiving that Notice, and (iii) successfully obtain the full 30-month stay, then the Applicant would be precluded from commercializing a generic version of DEFINITY prior to the expiration of that 30-month stay period and, potentially, thereafter, depending on how the patent dispute is resolved. Solely by way of example and not based on any knowledge we currently have, if we received a Notice from an Applicant in March 20222024 and the full 30-month stay were obtained, then the Applicant would be precluded from commercialization until at least September 2024.2026. If we received a Notice some number of months in the future and the full 30-month stay were obtained, the commercialization date would roll forward in the future by the same number of months. In the event a 505(b)(2) applicant does not rely on studies related to the innovator product, the 30-month stay would not apply, but additional clinical studiestrials may be required.
TechneLite - We currently own patents in the U.S. and various foreign countries on certain component technology expiring in 2029, and we are pursuing additional patent protection in the U.S. and world-wide on other component technology that, if granted, would expire in 2040. In addition, given the significant know-how and trade secrets associated with the methods of manufacturing and assembling the TechneLite generator, we believe we have a substantial amount of valuable and defensible proprietary intellectual property associated with the product.
PYLARIFY- We actively pursue patents in connection with PYLARIFY, both in the U.S. and internationally. In the U.S. for PYLARIFY, we have four Orange Book-listed patents, including composition of matter patents which expire in 2030 and 2037. Outside of the U.S., we are currently pursuing additional PYLARIFY patents to obtain similar patent protection as in the U.S.

PSMA TTC - We own and in-license composition of matter patents on PSMA antibodies expiring in the U.S. in 2022 and 2023 and outside of the U.S. in 2022.
In addition to patents, we rely, where necessary, upon unpatented trade secrets and know-how, proprietary information and continuing technological innovation to develop and maintain our competitive position. We seek to protect our proprietary information, in part, using confidentiality agreements with our collaborators, employees, consultants and other third parties and invention assignment agreements with our employees. These confidentiality agreements may not prevent unauthorized disclosure of trade secrets and other proprietary information, and we cannot provide assurances that an employee or an outside party will not make an unauthorized disclosure of our trade secrets, other technical know-how or proprietary information. We may not have adequate monitoring abilities to discover, or adequate remedies for, any unauthorized disclosure. This might happen intentionally or inadvertently. It is possible that a competitor will make use of such information, and that our competitive position will be compromised, in spite of any legal action we might take against persons making such unauthorized disclosures. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our collaborators, employees and consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.
In addition, we license third partythird-party technologies and other intellectual property rights that are incorporated into some elements of our drug discovery and development efforts. Some of these licenses are material to our business – for example, the licenses on the PYLARIFY patent family from Johns Hopkins University (“JHU”) and on the patent rights on RELISTOR from Wyeth LLC.

Regulatory Matters
Food and Drug Laws
The development, manufacture and commercialization of our products are subject to comprehensive governmental regulation both within and outside the U.S. A number of factors substantially increase the time, difficulty and costs incurred in obtaining and maintaining the approval to market newly developed and existing products. These factors include governmental regulation, such as detailed inspection of and controls over research and laboratory procedures, clinical investigations,trials, manufacturing, marketing, advertising and promotion, sampling, distribution, import and export, record keeping and storage and disposal practices, together with various post-marketing requirements. Governmental regulatory actions can result in the seizure or recall of products, suspension or revocation of the authority necessary for their production and sale as well as other civil or criminal sanctions.

Table of Contents

Our activities related to the development, manufacture, packaging or repackaging of our products subject us to a wide variety of laws and regulations. We are required to register for permits and/or licenses with, seek approvals from and comply with operating and security standards of, the FDA, the U.S. Nuclear Regulatory Commission (“NRC”), the U.S. Department of Health and Human Services (“HHS”), Health Canada, the European Medicines Agency (“EMA”), the U.K. Medicines and Healthcare Products Regulatory Agency (“MHRA”), the NMPA and various state and provincial boards of pharmacy, state and provincial controlled substance agencies, state and provincial health departments and/or comparable state and provincial agencies, as well as foreign agencies, and certain accrediting bodies depending upon the type of operations and location of product distribution, manufacturing and sale.
The FDA and various state regulatory authorities regulate the research, testing, manufacture, safety, labeling, storage, recordkeeping, premarket approval, marketing, advertising and promotion, import and export, and sales and distribution of pharmaceutical products in the U.S. Prior to marketing a pharmaceutical product, we must first receive FDA approval. In the U.S., the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (“FDCA”) and implementing regulations. The process of obtaining regulatory approvals and compliance with appropriate federal, state, local, and foreign statutes and regulations requires the expenditure of substantial time and financial resources. Currently, the process required by the FDA before a drug product may be marketed in the U.S. generally involves the following:
Completion of preclinical laboratory tests, animal studies and formulation studies according to current Good Laboratory Practices regulations;
Submission to the FDA of an investigational new drug application (“IND”) which must become effective before human clinical studiestrials may begin, including review and approval by any institutional review board (“IRB”), serving any of the institutions participating in the clinical studies;trials;
Performance of adequate and well-controlled human clinical studiestrials according to current Good Clinical Practices and other requirements, to establish the safety and efficacy of the proposed drug product for its intended use;
Submission to the FDA of a new drug application (“NDA”)an NDA for a new drug;
Satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug product is produced to assess compliance with current Good Manufacturing Practices (“cGMPs”) regulations; and
FDA review and approval of the NDA.
The testing and approval process requires substantial time, effort, and financial resources, and we cannot be certain that any approvals for our agentsproducts in development will be granted on a timely basis, if at all. Once a pharmaceutical agentproduct is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product chemistry, toxicity, formulation, and stability, as well as animal studies to assess its potential safety and efficacy. This testing culminates in the submission of the IND to the FDA.
Once the IND becomes effective, including review and approval by any IRB serving any of the institutions participating in the clinical trial, the clinical trial program may begin. Each new clinical trial protocol must be submitted to the FDA before the studytrial may begin. The person, entity or organization taking responsibility for the trial is referred to as the clinical trial sponsor. Human clinical studiestrials are typically conducted in three sequential phases that may overlap or be combined:
Phase 1. The agentproduct is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of some products for severe or life-threatening diseases, especially when the agentproduct may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients with those diseases.
18

Table of Contents

Phase 2. Involves studiestrials in a limited patient population to identify possible adverse effects and safety risks, to evaluate preliminarily the efficacy of the agentproduct for specific targeted diseases and to determine dosage tolerance and optimal dosage and schedule.
Phase 3. Clinical studiestrials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical studytrial sites. These studiestrials are intended to collect sufficient safety and efficacy data to support the NDA for FDA approval.
Progress reports detailing the results of the clinical studiestrials must be submitted at least annually to the FDA and safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events. Submissions must also be made to inform the FDA of certain changes to the clinical trial protocol. Federal law also requires the sponsor to register the trials on public databases when they are initiated, and to disclose the results of the trials on public databases upon completion. Phase 1, Phase 2 and Phase 3 testingclinical trials may not be completed successfully within any specified period, if at all. The FDA or the clinical trial sponsor may suspend or terminate a clinical studytrial at any time on various grounds, including a finding that the research subjects or patients are being
19

Table of Contents

exposed to an unacceptable health risk. Similarly, any IRB serving any of the institutions participating in the clinical trial can suspend or terminate approval of a clinical studytrial at a relevantan institution if the clinical studytrial is not being conducted in accordance with the IRB’s requirements or if the agentproduct has been associated with unexpected serious harm to patients. Failure to register a clinical trial or disclose study results within the required time periods could result in penalties, including civil monetary penalties.
Concurrent with clinical studies,trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the agentproduct and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the agentproduct does not undergo unacceptable deterioration over its shelf life.
The results of product development, preclinical studies and clinical studies,trials, along with descriptions of the manufacturing process, analytical tests conducted on the drug product, proposed labeling, and other relevant information, are submitted to the FDA as part of an NDA for a new drug, requesting approval to market the agent.product. The submission of an NDA is subject to the payment of a substantial user fee. A waiver of that fee may be obtained under certain limited circumstances. The approval process is lengthy and difficult, and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied. The FDA has substantial discretion in the product approval process, and it is impossible to predict whether and when the FDA will grant marketing approval. The FDA may on occasion require the sponsor of an NDA to conduct additional clinical studiestrials or to provide other scientific or technical information about the product, and these additional requirements may lead to unanticipated delay or expense. Even if such data and information are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical studiestrials are not always conclusive, and the FDA may interpret data differently than we interpret the same data.
If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. In addition, the FDA may require Phase 4 testing which involves clinical studiestrials designed to further assess a drug product’s safety and effectiveness after NDA approval. The FDA also may impose one or more Risk Evaluation and Mitigation Strategies (“REMS”) to ensure that the benefits of a product outweigh its risks. A REMS could add training requirements for healthcare professionals, safety communications efforts and limits on channels of distribution, among other things. The sponsor would be required to evaluate and monitor the various REMS activities and adjust them if need be. Whether a REMS would be imposed on any of our products and any resulting financial impact is uncertain at this time.
Under the Orphan Drug Act, the FDA may designate a product as an Orphan Drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States. AZEDRA currently has the Orphan Drug designation in the United States.
In the United States, Orphan Drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers. In addition, if a product that has Orphan Drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to Orphan Drug exclusivity, which means the FDA may not approve any other application to market the same drug for the same indication for a period of seven years, except in limited circumstances, such as a showing of clinical superiority over the product with orphan exclusivity or where the manufacturer is unable to assure sufficient product quantity.

Under Section 529 of the FDCA, companies that develop new drugs for the prevention and treatment of certain rare pediatric diseases may be eligible for a rare pediatric disease priority review voucher for a subsequent human drug application. The voucher is only granted if the drug is approved for the rare pediatric disease, but once granted, the voucher can either be used by the recipient or sold to a third party, typically a large pharmaceutical or related company that seeks priority review for an unrelated drug it expects will generate substantial revenue. Pursuant to federal legislation passed and signed into law in late 2020, the expiration date of the rare pediatric disease priority review voucher program was extended from September 30, 2022 to September 30, 2026.
Any drug products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, complying with certain electronic records and signature requirements, and complying with FDA promotion and advertising requirements. The FDA strictly regulates labeling, advertising, promotion and other types of information on drug products that are placed on the market. Drugs may be promoted only for the approved indications and consistent with the provisions of the approved label and promotional claims must be appropriately balanced with important safety information and otherwise be adequately substantiated. Further, manufacturers of drugs must continue to comply with cGMP requirements, which are extensive and require considerable time, resources and ongoing investment to ensure compliance. In addition, changes to the manufacturing process generally require prior FDA approval before being implemented, and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Drug product manufacturers and other entities involved in the manufacturing and distribution of approved drugs products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain other agencies for compliance with cGMP and other laws. The cGMP requirements apply to all stages of the manufacturing process, including the production, processing, sterilization, packaging, labeling, storage and shipment of the drug product. Manufacturers must establish validated systems to ensure that products meet specifications and regulatory standards, and test each product batch or lot prior to its release. In addition, manufacturers of commercial PET products such as PYLARIFY, including radiopharmacies, hospitals and academic medical centers, are required to submit either an NDA or ANDA in order to produce PET drugs for clinical use, or produce the drugs under an IND.
The FDA also regulates the preclinical and clinical testing, design, manufacture, safety, efficacy, labeling, storage, record keeping, sales and distribution, post-market adverse event reporting, import/export and advertising and promotion of any medical devices that we distribute pursuant to the FDCA and FDA’s implementing regulations. The Federal Trade Commission shares jurisdiction with the FDA over the promotion and advertising of certain medical devices. The FDA can also impose restrictions on the sale, distribution or use of medical devices at the time of their clearance or approval, or subsequent to marketing. Currently, medical devices comprise only a small portion of our revenues.
The FDA may withdraw marketing authorization for a product if compliance with regulatory standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously-unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market. Further, the failure to maintain compliance with regulatory requirements may result in administrative or judicial actions, such as fines, civil monetary penalties, warning letters, holds on clinical studies,trials, product recalls or seizures, product detention or refusal to permit the import or export of products, refusal to approve pending applications or supplements, restrictions on marketing or manufacturing, injunctions, or civil or criminal penalties.
Regulations are subject to change as a result of legislative, administrative or judicial action, which may also increase our costs or reduce sales or otherwise adversely impact our products. For example, on April 16, 2021 in the case Genus Medical Technologies LLC v. Food and Drug Administration, the U.S. Court of Appeals for the D.C. Circuit held that a product (other than a combination product) that meets the definitions of both “drug” and “device” under the FDCA must be regulated as a device. On August 9, 2021, the FDA announced that, as part of its implementation of this court decision, the FDA intended to regulate products that meet both the device and drug definition as devices, except where Congress intended a different classification. The FDA further indicated that it intended to bring previously classified products into line with the court decision and would reexamine whether individual imaging agents meet the device definition. In connection with its announcement,definition, which raised uncertainty as to how our some of our products would be regulated. Congress subsequently resolved this issue when it passed the FDA requested comments fromConsolidated Appropriations Act of 2023, which amended the industry on five topics: categories of products implicatedFDCA by the court decision; the transition process; the transition timing; user fee transitions; and determiningadding a provision that deemed any contrast agent or radioactive drug or device status. We submitted comments to the FDA in response to its request for comments. While we question whether the FDA has authority to make this change, we believe that pre-existing law already establishes that a broad spectrum of imaging agents have already been established by Congress to be “drugs”, and do not believe that any of our imaging agents meets the definition of a “device” under the FDCA. We can give no assurance that the FDA will agree with our position. In addition, if the FDA determines that one or more of our imaging agents meet the definition of a “device”, we do not know when such reclassification would be effective, how any transition rules would be formulated or applied, and whether or not the legal framework provided by the Hatch-Waxman Act described below would be preserved for some time after such reclassification. A reclassification of one or more of our imaging agents as a “device” could have a material adverse effect on our business, results of operations, financial condition and cash flows.

Because our operations include the manufacture and distribution of medical radioisotopes and other medical products, we are subject to regulation by the NRC and the departments of health of each state in which we operate and the applicable state boards of pharmacy. In addition, the FDA is also involved in the regulation of cyclotron facilities where PET products are produced in compliance with cGMP requirements and U.S. Pharmacopeia requirements for PET drug compounding.
Drug laws also are in effect in many of the non-U.S. markets in which we or our partners conduct business. These laws range from comprehensive drug approval requirements to requests for product data or certifications. In addition, inspection of and controls over manufacturing, as well as monitoring of adverse events, are components of most of these regulatory systems. Most of our business is subject to varying degrees of governmental regulation in the countries in which we or our partners operate, and the general trend is toward increasingly stringent regulation. The exercise of broad regulatory powers by the FDA continues to result in increases in the amount of testing and documentation required for approval or clearance of new drugs and devices, all of which add to the expense of product introduction. Similar trends also are evident in major non-U.S. markets, including Canada, the European Union, Australia and Japan.
To assess and facilitate compliance with applicable FDA, NRC and other state, federal and foreign regulatory requirements, we regularly review our quality systems to assess their effectiveness and identify areas for improvement. As part of our quality review, we perform assessments of our suppliers of the raw materials that are incorporated into products and conduct quality management reviews designed to inform management of key issues that may affect the quality of our products. From time to time, we may determine that products we manufactured or marketed do not meet our specifications, published standards, such as those issued by the International Standards Organization, or regulatory requirements. When a quality or regulatory issue is identified, we investigate the issue and take appropriate corrective action, such as withdrawal of the product from the market, correction of the product at the customer location, notice to the customer of revised labeling and other actions.

Hatch-Waxman Act
The Hatch-Waxman Act added two pathways for FDA drug approval. First, the Hatch-Waxman Act permits the FDA to approve ANDAs for generic versions of drugs if the ANDA applicant demonstrates, among other things, that its product is bioequivalent to the innovator product and provides relevant chemistry, manufacturing and product data. See “Item 1. Business - Patents.” Second, the Hatch-Waxman Act created what is known as a Section 505(b)(2) NDA, which requires the same information as a full NDA (known as a Section 505(b)(1) NDA), including full reports of clinical and preclinical studies but allows some of the information from the reports required for marketing approval to come from studies which the applicant does not own or have a legal right of reference. A Section 505(b)(2) NDA permits a manufacturer to obtain marketing approval for a drug without needing to conduct or obtain a right of reference for all of the required studies. The Hatch-Waxman Act also provides for: (1) restoration of a portion of a product’s patent term that was lost during clinical development and application review by the FDA; and (2) statutory protection, known as exclusivity, against the FDA’s acceptance or approval of certain competitor applications.
Under U.S. law, patent term extension can compensate for time lost during product development and the regulatory review process by returning up to five years of patent life for a patent that covers a new product or its use. This period is generally one-half the time between the effective date of an IND and the submission date of an NDA, plus the time between the submission date of an NDA and the approval of that application. Patent term extensions, however, are subject to a maximum extension of five years, and the patent term extension cannot extend the remaining term of a patent beyond a total of 14 years. The application for patent term extension is subject to approval by the U.S. Patent and Trademark Office in conjunction with the FDA.
The Hatch-Waxman Act also provides for a period of statutory protection for new drugs that receive NDA approval from the FDA. If the FDA approves a Section 505(b)(1) NDA for a new drug that is a new chemical entity, meaning that the FDA has not previously approved any other new drug containing the same active moiety, then the Hatch-Waxman Act prohibits the submission or approval of an ANDA or a Section 505(b)(2) NDA for a period of five years from the date of approval of the NDA, except that the FDA may accept an application for review after four years under certain circumstances, specifically a patent challenge for one or more patents listed by the NDA holder in FDA’s publication, Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”), submitted in a “Paragraph IV” Certification. The Hatch-Waxman Act will not prevent the filing or approval of a full NDA, as opposed to an ANDA or Section 505(b)(2) NDA, for any drug, but the competitor would be required to conduct its own clinical trials, and any use of the drug for which marketing approval is sought could not violate another NDA holder’s patent claims. The Hatch-Waxman Act provides for a three-year period of exclusivity for an NDA for a new drug containing an active moiety that was previously approved by the FDA, but also includes new clinical data (other than bioavailability and bioequivalence studies) to support an innovation over the previously-approved drug and those studies were conducted or sponsored by the applicant and were essential to approval of the application. This three-year exclusivity period does not prohibit the FDA from accepting an application from a third party for a drug with that same innovation, but it does prohibit the FDA from approving that application for the three-year period. The three-year exclusivity does not prohibit the FDA, with limited exceptions, from approving generic drugs containing the same active ingredient but without the new innovation.

Reimbursement
The successful commercialization of our products is also subject to the availability of appropriate third-party coding, coverage and payment for our customers. Third-party payors in the U.S. include commercialprivate payors, including managed care providers, and State and Federal healthcare programs, such as Medicare and Medicaid. The process for determining whether a payor will provide coverage for a product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the product. Coverage of a product does not ensure there will be an appropriate reimbursement amount for such product and the process to ensure appropriate reimbursement is outside our control. For commercialprivate payors, coverage and reimbursement of our products vary from commercialprivate payor to commercialprivate payor. Many commercialprivate payors, such as managed care providers, manage access to products, and may use medical policies (which may include specific coverage requirements such as prior authorization, re-authorization and achieving performance metrics under value-based contracts) to control utilization. Exclusion from or restriction in coverage can reduce product use. For government payors, we participate, as required, in the Medicaid drug rebate program, the Federal Supply Schedule (FSS) and the PHS 340bPublic Health Service Act 340B program, which each require discounts for participation and may be subject to change. For Medicare, reimbursement to customers for our products is generally established through the rulemaking process or in discussion with Medicare Administrative Contractors (MACs). We have ongoing conversations with third-party payors to advocate for appropriate coding, coverage and payment for our portfolio of products, but we can give no assurance that adequate coding, coverage and payment can be obtained from such commercial or government payors.products.
Medicare Outpatient Pass-Through PaymentTPT Status
Part B of the Medicare program generally reimburses medical services and supplies, including drugs, provided to beneficiaries by physicians and other qualified healthcare professionals. Generally, drugs furnished “incident to” a physician’s service in the hospital outpatient setting of care are reimbursed at Average Sales Price (“ASP”) plus a certain additional percent, unless the product is treated as a “supply” in the performance of the procedure and “packaged” and paid as part of bundled payment for the procedure.

Novel drugs, however, may apply for “pass-through status”TPT Status in which case they are provided a separate payment at ASP plus a certain additional percent for two to three years, regardless of whether they would ordinarily be packaged.
PYLARIFY has received pass-through statusTPT Status effective January 1, 2022 through December 31, 2024, thereby providing separate reimbursement to customers using PYLARIFY in the hospital outpatient setting during this specified period. The reimbursement rate for PYLARIFY iswas initially based on the wholesale acquisition cost (WAC) plus three percent until ASP could be established. In 2023, CMS can establishestablished an ASP for the product, which could take six months. Once CMS establishesPYLARIFY and reimbursed at a rate equal to ASP plus an ASP, the add-on percentage applicable to PYLARIFY will likely vary.that varied throughout the year.
PYLARIFY has been assigned Healthcare Common Procedure Coding System code A9595 (piflufolastat F 18, diagnostic, 1 millicurie) for identification in claims and can be used by both public and commercialprivate payors. Under existing Medicare Part B payment policy for the hospital outpatient setting of care, non-pass-through diagnostic radiopharmaceuticals are not separately paid and are instead packaged into payment for the underlying procedure. Therapeutic radiopharmaceuticals however, continue to be eligible for separate payment even after expirationare paid separately by Medicare OPPS regardless of pass-through status.TPT Status. We plan to continue our advocacy efforts with CMS and private insurers so that PYLARIFY customers will have appropriate and adequate reimbursement following the expiration of pass-through status, although we can give no assurancesTPT Status. We are also supporting trade associations in their efforts to have Congress pass the Facilitating Innovative Nuclear Diagnostics (FIND) Act, which would allow for separate payment for certain diagnostic radiopharmaceuticals, including PYLARIFY, similar to the way Medicare OPPS currently pays for other drugs, biologics, and therapeutic radiopharmaceuticals instead of under the current TPT structure of a separate payment that we will be successful in those efforts.is limited to three years.
Healthcare Reform and Other Laws Affecting Payment
We operate in a highly-regulatedhighly regulated industry. The U.S. and state governments continue to propose and pass legislation that may affect the availability and cost of healthcare. For example, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, the “Healthcare Reform Act”), substantially changes the way in which healthcare is financed by both governmental and private insurers and has a significant impact on the pharmaceutical industry. The Healthcare Reform Act contains a number of provisions that affect coverage, reimbursement and/or delivery of drug products and the medical imaging procedures in which our drug products are used. Key provisions that currently affect our business include the following:
increasing the presumed utilization rate for imaging equipment costing $1.0 million or more in the physician office and free-standing imaging facility setting which reduces the Medicare per procedure medical imaging reimbursement; which rate was further increased by subsequent legislation effective January 1, 2014;
increasing drug rebates paid to state Medicaid programs under the Medicaid Drug Rebate Program for brand name prescription drugs and extending those rebates to Medicaid managed care organizations;
expanding access to the 340B program by allowing additional covered entities to participate in the program; and
imposing a non-deductible annual fee on pharmaceutical manufacturers or importers who sell brand name prescription drugs to specified federal government programs.

The Healthcare Reform Act also amended the federal self-referral laws, requiring referring physicians to inform patients under certain circumstances that the patients may obtain services, including PET, CT, MRI and certain other diagnostic imaging services, from a provider other than that physician, another physician in his or her group practice, or another individual under direct supervision of the physician or another physician in the group practice. The referring physician must provide each patient with a written list of other suppliers who furnish those services in the area in which the patient resides. These requirements could have the effect of shifting where certain diagnostic medical imaging procedures are performed.
The Healthcare Reform Act has been subject to political and judicial challenges, but it has generally withstood such challenges, and the main provisions of the Healthcare Reform Act remain in effect.
Recently, there has been considerable public and government scrutiny More recently, Congress enacted the Inflation Reduction Act of 2022 (the “IRA”) which significantly impacts the pharmaceutical pricing and proposals to addressindustry. Among other provisions, the perceived high cost of pharmaceuticals at both the federal and state levels. Efforts by government officials or legislators to implement measures to regulate prices or payment for pharmaceutical products could limit our flexibility in establishing prices for our products or otherwise adversely affect our business if implemented. For instance, Congress is currently considering the Build Back Better Act, which contains many drug pricing provisions that could adversely affect our business, including but not limited to authorization forIRA authorizes Medicare to directly negotiate pricing for high-costthe highest Medicare-spend drugs, as determined by their Medicare Part B and inflation penaltiesD spend, that have been on the market for an extended period of time without market competition. Although the IRA provides for a limited number of categorical exclusions from Medicare negotiation, radiopharmaceuticals are not among those categorical exclusions. CMS plans to begin implementing the first year of Medicare negotiation, which will be restricted to Part D drugs, starting in calendar years 2026 and 2027. We are currently focused on drugs that are covered under Part B, therefore we do not expect the Part D benefit redesign to have an impact on our portfolio. Part B drugs will be considered for Medicare negotiation beginning in calendar year 2028, and CMS will begin the process of identifying Part B drugs for negotiation as early as calendar year 2026. We are monitoring the implementation of the IRA to determine what impact, if any, this would have on our current products and product candidates in development.
The IRA also introduces rebate obligations for manufacturers of Part B and D drugs withthat take price increases greater thanwhich exceed the rate of inflation. Toinflation, similar to the longstanding Medicaid inflation rebates. Under these new Medicare inflation rebates, each Part B and D

If the manufacturer’s price increases for the relevant product exceeds the inflation adjusted payment amount, as trended forward by the rate of inflation, the manufacturer will be clear, changes could occur atrequired to reimburse Medicare the federal level or state leveldifference between what Medicare paid for the product and may be adopted by statute, rule, or sub-regulatory policies. what it would have paid based on the inflation adjusted payment amount.
Recent state legislative efforts seek to address drug costs and generally have focused on increasing transparency around drug costs or limiting drug prices. Some of those efforts have been subject to legal challenge.
General legislative cost control measures may also affect reimbursement for our products or services provided with our products. The Budget Control Act, as amended by the Bipartisan Budget Act of 2019, resulted in the imposition of 2% reductions in Medicare (but not Medicaid) payments to providers beginning in 2013 and will remain in effect through fiscal year 2030 unless additional Congressional action is taken. The Coronavirus Aid, Relief, and Economic Security (CARES) Act suspendedimposition of the 2% payment adjustment for dates of service from May 1had been suspended through December 31, 2020, the Consolidated Appropriations Act 2021 subsequently extended this suspension until March 31, 2021,2022 and Congress further extended the suspension through March 31,went into effect as of April 1, 2022. Any significant spending reductions affecting Medicare, Medicaid or other publicly funded or subsidized health programs that may be implemented and/or any significant taxes or fees that may be imposed on us could have an adverse impact on our business results of operations, financial condition and cash flows.
Healthcare Fraud and Abuse Laws
We are subject to various federal, state and local laws targeting fraud and abuse in the healthcare industry, including anti-kickback and false claims laws. Patient assistance programs, if not properly implemented, can implicate these laws. Violations of fraud and abuse laws may be punishable by criminal or civil sanctions, including fines and civil monetary penalties, and/or exclusion from federal health care programs (including Medicare and Medicaid). Federal and state authorities are paying increased attention to enforcement of these laws within the pharmaceutical industry, and private individuals have been active in alleging violations of the laws and bringing suits on behalf of the government under the federal False Claims Act (“FCA”). Violations of international fraud and abuse laws could result in similar penalties, including exclusion from participation in health programs outside the U.S. If we were subject to allegations concerning, or were convicted of violating, these laws, our business could be harmed.
The federal Anti-Kickback Statute generally prohibits, among other things, a pharmaceutical manufacturer from directly or indirectly soliciting, offering, receiving, or paying any remuneration in cash or in kind where one purpose is either to induce the referral of an individual for, or the purchase or prescription of a particular drug that is payable by a federal health care program, including Medicare or Medicaid. The Healthcare Reform Act clarifies the intent requirements of the federal Anti-Kickback Statute, providing that a person or entity does not need to have actual knowledge of the statute or a specific intent to violate the statute. Violations of the federal Anti-Kickback Statute can result in exclusion from Medicare, Medicaid or other governmental programs as well as civil and criminal fines and penalties of up to $104,330 per violation and three times the amount of the unlawful remuneration. In addition, the Healthcare Reform Act revised the FCA to provide that a claim arising from a violation of the Federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the FCA. The majority of states also have anti-kickback, false claims, and similar fraud and abuse laws and although the specific provisions of these laws vary, their scope is generally broad, and there may not be regulations, guidance or court decisions that apply the laws to particular industry practices. There is, therefore, a possibility that our practices might be challenged under the anti-kickback statutes or similar laws.

Table of Contents

Federal and state false claims laws generally prohibit anyone from knowingly and willfully, among other activities, presenting, or causing to be presented for payment to third party payors (including Medicare and Medicaid) claims for drugs or services that are false or fraudulent (which may include claims for services not provided as claimed or claims for medically unnecessary services). As discussed, a claim arising from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the FCA. False or fraudulent claims for purposes of the FCA carry fines and civil penalties for violations ranging from $11,665 to $23,331 for each false claim, plus up to three times the amount of damages sustained by the federal government and, most critically, may provide the basis for exclusion from federally funded healthcare programs. There is also a criminal FCA statute by which individuals or entities that submit false claims can face criminal penalties. In addition, under the federal Civil Monetary Penalty Law, the Department of Health and Human Services Office of Inspector General has the authority to exclude from participation in federal health care programs or to impose civil penalties against any person who, among other things, knowingly presents, or causes to be presented, certain false or otherwise improper claims. Our activities relating to the sale and marketing of our products may be subject to scrutiny under these laws.

Table of Contents

Laws and regulations have also been enacted by the U.S. federal government and various states, as well as by countries outside of the U.S., to regulate the sales and marketing practices of certain entities including pharmaceutical and device manufacturers. The laws and regulations generally limit financial interactions between manufacturers and health care providers; require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the U.S. federal government; and/or require disclosure by pharmaceutical and device manufacturers to the government and/or public of financial interactions or other financial relationships with health care providers and other entities such as teaching hospitals (so-called “sunshine laws”). The Healthcare Reform Act requires manufacturers to submit information to the FDA on the identity and quantity of drug samples requested and distributed by a manufacturer during each year. Many of these laws and regulations contain ambiguous requirements or require administrative guidance for implementation. The laws and regulations include requirements that can be unclear in their scope, nature, and required implementation by regulated entities. If we fail to comply with such laws and regulations, we could be subject to penalties and administrative actions under such laws and regulations.
Data Privacy, Security and Breach Notification
We are subject to data protection laws and regulations that set forth data privacy, security, and breach notification requirements. The legislative and regulatory landscape for data protection continues to evolve, and in recent years there has been an increasing focus on data protection and other data privacy and security issues. In the United States, numerous federal and state laws and regulations, including state data breach notification laws, state health information privacy laws and federal and state consumer protection laws govern the collection, use, disclosure and protection of health-related and other personal information. In addition to establishing restrictions on how personal information may be collected, used, and disclosed, these laws and regulations provide various rights to data subjects with respect to their personal information and establish requirements for how personal information must be secured. In addition, every state in the United States now has a data breach notification law that requires regulated entities to report certain security breaches to affected data subjects, regulators, or other entities. Failure to comply with data protection laws and regulations could result in government enforcement actions (which could include civil or criminal penalties and requirements to take corrective actions), private litigation (which may result in the award of damages against us), and/or adverse publicity, and could negatively affect our operating results, business, and reputation. In addition, we may obtain health information from third parties (e.g., healthcare providers who prescribe our products) that are themselves subject to privacy, security, and breach notification requirements under the Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act (collectively, “HIPAA”). While we believe that we are neither a “covered entity” nor “business associate” subject directly to regulation under HIPAA, HIPAA’s criminal provisions can apply to entities other than “covered entities” or “business associates” in certain circumstances. Accordingly, we could be subject to criminal penalties if we knowingly obtain or disclose individually identifiable health information from a HIPAA-covered entity in a manner that is not authorized or permitted.
In addition, a growing number of jurisdictions outside of the United States have enacted robust data protection laws. Certain of these laws have extraterritorial application. For example, the processing of personal data in the European Union is governed by the provisions of the General Data Protection Regulation, or GDPR, which came into effect on May 25, 2018. The GDPR applies to an entity established in the EU and extraterritorially to an entity outside of the EU that offers goods or services to, or monitors the behavior of, individuals located in the EU. Certain “special categories” of personal data, including data concerning health, are subject to enhanced protections under the GDPR. This regulation imposes several requirements on the controllers and processors of personal data, including the obligation to comply with various rights that individuals have with respect to their personal data and restrictions on the processing of personal data, and to provide notice of data processing obligations to the competent national data protection authorities. The GDPR also imposes strict rules on the transfer of personal data out of the European Union to the United States. Failure to comply with the requirements of the GDPR and the related national data protection laws of the European Union Member States may result in significant fines and other administrative penalties.
In the United States, several state legislatures are considering enacting new data privacy legislation. One example of such legislation that has already been passed is the California Consumer Privacy Act (“CCPA”), which took effect on January 1, 2020 and
24

Table of Contents

imposes many requirements on certain for-profit businesses that process the personal information of California residents. Many of the CCPA’s requirements are similar to those found in the GDPR, including requiring businesses to provide notice to data subjects regarding the information collected about them and how such information is used and shared, and providing data subjects various rights, such as the right to request access to their personal information and, in certain cases, request the erasure of such personal information. The CCPA also affords California residents the right to opt-out of the “sale” of their personal information. In addition, the CCPA requires regulated businesses to implement reasonable security procedures and practices to protect personal information. The CCPA contains significant penalties for companies that violate its requirements. It also provides California residents a private right of action, including the ability to seek statutory damages, in the event of a breach involving their personal information resulting from a business’s failure to implement and maintain reasonable security procedures and practices. Compliance with the CCPA, and similar laws implemented in other states, is a rigorous and time-intensive process that may increase the cost of doing business or require companies to change their business practices to ensure full compliance.
25

Table of Contents

On November 3, 2020, California passed the California Privacy Rights Act (“CPRA”) through a ballot initiative. The CPRA amends the CCPA and expands its protections for personal information, including by establishing a new California Privacy Protection Agency to enforce the CPRA and by providing California consumers various rights such as the right to restrict the processing of their “sensitive personal information.” The CPRA’s amendments to the CCPA taketook effect on January 1, 2023, and generally will apply to personal information collected by regulated businesses on or after January 1, 2022. The California Attorney General will have authority to begin enforcing the CPRA’s amendments to the CCPA beginning on July 1, 2022.
Antitrust and Competition Laws
The federal government and most states have enacted antitrust laws that prohibit specific types of anti-competitive conduct, including price fixing, wage fixing, concerted refusals to deal, price discrimination and tying arrangements, as well as monopolization and acquisitions of competitors that have, or may have, a substantial adverse effect on competition. Violations of federal or state antitrust laws can result in various sanctions, including criminal and civil penalties. We believe we are in compliance with such federal and state laws, but courts or regulatory authorities may reach a determination in the future that could adversely affect our business, results of operations, financial condition and cash flows. In addition, we are subject to similar antitrust and anti-competition laws in foreign countries. We believe we are in compliance with such laws, however, any violation could create a substantial liability for us and also cause a loss of reputation in both foreign and domestic markets. 
Laws Relating to Foreign Trade
We are subject to various federal and foreign laws that govern our international business practices with respect to payments to government officials. Those laws include the Foreign Corrupt Practices Act (“FCPA”) which prohibits U.S. companies and their representatives from paying, offering to pay, promising, or authorizing the payment of anything of value to any foreign government official, government staff member, political party, or political candidate for the purpose of obtaining or retaining business or to otherwise obtain favorable treatment or influence a person working in an official capacity. In many countries, the healthcare professionals we regularly interact with may meet the FCPA’s definition of a foreign government official. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect their transactions and to devise and maintain an adequate system of internal accounting controls.
Those laws also include the U.K. Bribery Act (“Bribery Act”) which proscribes giving and receiving bribes in the public and private sectors, bribing a foreign public official, and failing to have adequate procedures to prevent employees and other agents from giving bribes. U.S. companies that conduct business in the United Kingdom generally will be subject to the Bribery Act. Penalties under the Bribery Act include potentially unlimited fines for companies and criminal sanctions for corporate officers under certain circumstances.
Our policies mandate compliance with these anti-bribery laws. Our operations reach many parts of the world that have experienced governmental corruption to some degree, and in certain circumstances strict compliance with anti-bribery laws may conflict with local customs and practices. Despite our training and compliance programs, our internal control policies and procedures may not always protect us from reckless or criminal acts committed by our employees or agents.
We are also subject to trade control regulations and trade sanctions laws that restrict the movement of certain goods, currency, products, materials, services and technology to, and certain operations in, various countries or with certain persons. Our ability to transfer people and products among certain countries may be subjected to these laws and regulations.
Health and Safety Laws
We are also subject to various federal, state and local laws, regulations and recommendations, both in the U.S. and abroad, relating to safe working conditions, laboratory and manufacturing practices and the use, transportation and disposal of hazardous or potentially hazardous substances.

Environmental Matters
We are subject to various federal, state and local laws and regulations relating to the protection of the environment, human health and safety in the U.S. and in other jurisdictions in which we operate. Our operations, like those of other medical product companies, involve the transport, use, handling, storage, exposure to and disposal of materials and wastes regulated under environmental laws, including hazardous and radioactive materials and wastes. If we violate these laws and regulations, we could be fined, criminally charged or otherwise sanctioned by regulators. We believe that our operations currently comply in all material respects with applicable environmental laws and regulations.

Table of Contents

Certain environmental laws and regulations assess liability on current or previous owners or operators of real property for the cost of investigation, removal or remediation of hazardous materials or wastes at those formerly owned or operated properties or at third party properties at which they have disposed of hazardous materials or wastes. In addition to cleanup actions brought by governmental authorities, private parties could bring personal injury, property damage or other claims due to the presence of, or exposure to, hazardous materials or wastes. We currently are not party to any claims or any obligations to investigate or remediate any material contamination at any of our facilities.facilities, however, if we were found to be liable under one or more of these laws or regulations, it could create a substantial liability.
We are required to maintain a number of environmental permits and nuclear licenses for our North Billerica, Massachusetts facility,campus, which isincludes our primary manufacturing, packaging and distribution facility. In particular, we must maintain a nuclear byproducts materials license issued by the Commonwealth of Massachusetts. This license requires that we provide financial assurance demonstrating our ability to cover the cost of decommissioning and decontaminating (“D&D”) the Billerica site at the end of its use as a nuclear facility. In addition, we have a radioactive production facility in Somerset, NJ where we must also maintain a number of environmental permits and nuclear licenses. We store low level radioactive waste at our facilities until the materials are below regulatory limits, as allowed by our licenses and permits. As of December 31, 2021,2023, we currently estimate the D&D cost of all of our manufacturing sites (excluding our Puerto Rico radiopharmacy, which we sold on January 29, 2021) to be approximately $26.4$25.1 million. As of December 31, 20212023 and 2020,2022, we have a liability recordedof approximately $22.9 million and $22.5 million, respectively associated with the fair value of theour asset retirement obligations of $20.8 million and $14.0 million, respectively.obligations. We currently provide this financial assurance in the form of surety bonds.
We also actively monitor and seek to reduce our solid waste, energy and water usage, waste water discharge and greenhouse gas emissions. We generally contract with third parties for the disposal of wastes generated by our operations. In 2020, we developed a stormwater management operations and maintenance plan to minimize stormwater pollution from high impact activities. Improvements we made include (i) the regular inspection and cleaning of catch basins and piping to reduce sediment and debris wash out to adjacent wetlands; (ii) increasing street and parking lot cleaning to reduce pollutant run off; (iii) updating our snow removal plan at our North Billerica sitecampus to reduce the impact to adjacent wetlands; and (iv) using salt brine as a pretreatment for winter storms to reduce the amount of salt use and run off.
With respect to sustainability, in 2020, we developed a mechanism to track and monitor our energy use, water use, a limited scope of greenhouse gas emissions, and waste generation. We use an Energy Star Portfolio Manager to track energy and water use that we believe will help us calculate associatedand have calculated scope 1 and 2 greenhouse gas emissions and compare the performance offor our North Billerica buildingsCampus, with plans to expand these activities to other Lantheus properties. We will continue to compare our usage data against a yearly baseline,annual baselines, national medians, and other similar buildings.
Environmental laws and regulations are complex, change frequently and have become more stringent over time. While we have budgeted for future capital and operating expenditures to maintain compliance with these laws and regulations, we cannot assure you that our costs of complying with current or future environmental protection, health and safety laws and regulations will not exceed our estimates or adversely affect our results of operations and financial condition. Further, we cannot assure you that we will not be subject to additional environmental claims for personal injury or cleanup in the future based on our past, present or future business activities. While it is not feasible to predict the future costs of ongoing environmental compliance, it is possible that there will be a need for future provisions for environmental costs that, in management’s opinion, are not likely to have a material effect on our financial condition, but could be material to the results of operations in any one accounting period.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with environmental matters.
Human Capital Management
As of December 31, 2021,2023, we had 612834 employees, of which 588808 were located in the U.S. and 2426 were located internationally. None of our employees are represented by a collective bargaining agreement, and we believe that our relationship with our employees is good. During 2021, we hired additional employees to assist us with the commercialization of PYLARIFY, including in sales, marketing, reimbursement, quality and medical affairs. In addition, we hired a Chief Human Resources Officer to help us attract, develop and retain leading and diverse talent in business-critical roles.

Diversity, Inclusion, Ethics and Compliance
We believe that supporting our local community and instilling a diverse, inclusive, ethical and compliant culture makes us an employer of choice, allows us to maintain good standing with the regulatory authorities and our customers, and benefits our stockholders in the long run.
We have a female Chief Executive Officer who, effective March 1, 2024, will transition to Chair of the Board, over half of our Vice Presidents and above (including our senior management team, which we refer to as our “Expanded Executive Team”) are women, and approximately 46%50% of our employees are women. We continue to strive to improve our diversity and inclusion with a strategic emphasis beyond gender, and we require recruiters working with us to present diversitydiverse candidates. We also sponsor three Employee Resource Groups (“ERGs”), the Lantheus Diversity Connection ERG, the Women Leaders of Lantheus ERG, and the Professional Networking at Lantheus ERG.

We are committed to promoting a culture of ethics and compliance. Our Code of Conduct and Ethics reflects our commitment to corporate integrity and the underlying business practices and principles of behavior that support this commitment. Each year our employees complete mandatory training that includes anti-bribery/anti-corruption rules, insider trading prohibitions, confidentiality obligations, as well as specialized training in healthcare industry marketing practices. We have a formal Ethics and Compliance Committee that develops, implements and oversees our ethics and compliance programs. We also have a Supplier Code of Conduct, and we seek to do business with minority-owned, female-owned and other diverse businesses and organizations (including those owned or operated by veterans and disabled veterans) that appropriately reflect the communities in which we operate and the customer base we serve.
Compensation and Benefits
We seek to provide pay, benefits, and services that are competitive to market and create incentives to attract and retain employees. Our compensation package includes, among other things, market-competitive pay, cash bonuses, healthcare and defined contribution plan benefits, paid time off and family leave, and restricted stock and other equity grants to certain levels of employees. We are focused on pay equity and regularly assess pay among similar roles and responsibilities throughout our organization and in comparison to our peer group.
Communication and Engagement
We believe that our success depends on employees understanding how their work contributes to our overall strategy. To this end, we utilize a variety of channels to facilitate open and direct communication, including: (i) quarterly town hall meetings for our entire company; (ii) regular ongoing update communications;communications, including through monthly newsletters and our recently launched intranet site; and (iii) an externally administered whistleblower hotline and website that is prominently advertised to our employees, and a whistleblower’s anonymity is protected, if so requested. We also established various employee recognition award programs to recognize and reward employees for specific outstanding accomplishments and to foster a positive employee relations climate.
Health, Wellness and Safety
We are committed to the health and safety of our employees, patients and other partners in the healthcare community. We work to promote an environment of awareness and shared responsibility for safety and regulatory compliance throughout the Company, in order to minimize risks of injury, exposure, or business impact.
With respect to the COVID-19 pandemic, we operated a “Pandemic Response Team” to implement and oversee appropriate precautions to minimize the spread of COVID-19 in our teams and communities. We continue to have all non-critical employees and contractors work-remotely and avoid non-essential work-related travel. Further, we established a “Return to Office” team to develop plans for employees to safely return to all our facilities.
Corporate History
Founded in 1956 as New England Nuclear Corporation, our medical imaging diagnostic business was purchased by E.I. du Pont de Nemours and Company (“DuPont”) in 1981. Bristol Myers Squibb (“BMS”) subsequently acquired our diagnostic medical imaging business as part of its acquisition of DuPont Pharmaceuticals in 2001. In January 2008, Avista Capital Partners, L.P., Avista Capital Partners (Offshore), L.P. and ACP-Lantern Co-Invest, LLC formed Lantheus Holdings and acquired our medical imaging business from BMS. On June 30, 2015, we completed an initial public offering of our common stock. We completed our acquisition of Progenics on June 19, 2020 (the “Progenics Acquisition”). We completed our acquisition of Cerveau Technologies, Inc. on February 6, 2023 (the “Cerveau Acquisition”). Our common stock is traded on the NASDAQ Global Market under the symbol “LNTH”.

Item 1A. Risk Factors
You should carefully consider the following risks. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. These risks could materially affect our business, results of operations or financial condition, cause the trading price of our outstanding common stock to decline materially or cause our actual results to differ materially from those expected or those expressed in any forward-looking statements made by us or on our behalf. See “Cautionary Note Regarding Forward-Looking Statements” and the risks of our businesses described elsewhere in this Annual Report on Form 10‑K.
Risk Factor Summary
Our business is subject to a number of risks, including risks that may adversely affect our business, results of operations, cash flows, and prospects. These risks are discussed more fully below and include, but are not limited to, risks related to:
Risks Related to Our Portfolio of Commercial Products
Our ability to continue to grow the appropriate use of DEFINITY in suboptimal echocardiograms in the face of segment competition from other echocardiography ultrasound enhancing agents and potential generic competition as a result of patent and regulatory exclusivity expirations.
Our dependence upon third parties for the manufacture and supply of a substantial portion of our products, raw materials and components, including DEFINITY at JHS and DEFINITY RT at SBL.
The instability of the global Mo-99 supply, including periodic supply outages and limitations at the NTP Radioisotopes (“NTP”) processing facility in South Africa and the Australian Nuclear Science and Technology Organisation’s (“ANSTO”) processing facility in Australia, in each case resulting in our inability to fill some or all of the demand for our TechneLite generators on certain manufacturing days during the outage or limitation periods.
Our ability to successfully launch PYLARIFY as a commercial product includingis dependent on (A) the ability of PMFs to manufacture PYLARIFY to meet product demand, (B) our ability to obtain FDA approval for additional PMFs that could manufacture PYLARIFY, (B) the ability of those PMFs to supplypromote PYLARIFY to customers, (C) our ability to sell PYLARIFY to customers, and (D) our ability to obtain and maintain adequate coding, coverage and payment for PYLARIFY.PYLARIFY, (D) our ability to maintain PYLARIFY as the leading PSMA PET imaging agent, including after the potential expiration of TPT Status at the end of 2024 and (E) our ability to clinically and commercially differentiate PYLARIFY from other products.
To manufacture PYLARIFY, we assembled and qualified a nationwide network of PMFs with radioisotope-producing cyclotrons that make F 18, which has a 110-minute half-life, so PYLARIFY is manufactured and distributed rapidly to end-users. Because each of the PMFs manufacturing these products is deemed by the FDA to be a separate manufacturing site, each has to be separately approved by the FDA. Although PYLARIFY is broadly available across the U.S., we continue to seek qualification for additional PMFs in 2024 and can give no assurance that the FDA will continue to approve PMFs in accordance with our planned roll-out schedule. If FDA approval of manufacturing sites is delayed or withdrawn, our business, results of operations, financial condition and cash flows could be adversely affected.
PYLARIFY is sold in the U.S. to hospitals, independent imaging centers and government facilities and sales are generated through an internal PYLARIFY sales team, as well as a sales team at some of our PMF partners. We generally do not use group purchasing arrangements to sell PYLARIFY and require each customer to enter into a contract directly with us or our PMFs. Our ability to continue to successfully launchgrow PYLARIFY AI as a commercial product.
Risks related to RELISTOR, commercialized by Bausch, and that the revenues generated for us thereby may not meet expectations.
Risks related to the commercialization of AZEDRA, includingdepends, in connection with market acceptance and reimbursement, that may cause the product not to meet revenue or operating income expectations.
Risks associated with our DEFINITY RT formulation, approved by the FDA in November 2020, includingpart, on our ability to gain post-approval market acceptancecontinue to enter into arrangements directly with the hospitals, independent imaging centers and government facilities that we serve. Any delay or inability to enter into these arrangements could have an adverse impact on our business, results of operations, financial condition and cash flows.
Obtaining adequate coding, coverage and payment.
Risks Relatedpayment for PYLARIFY is critical, including not only coverage from Medicare, Medicaid and other government payors, as well as private payors, but also appropriate payment levels to Reimbursement and Regulation
The dependenceadequately cover our customers’ costs of manyusing PYLARIFY in PET/CT imaging procedures. We received notification that our HCPCS code, which enables streamlined billing, went into effect as of our customers upon third party healthcare payorsJanuary 1, 2022. In addition, effective January 1, 2022, CMS granted TPT Status for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in the hospital outpatient setting. TPT Status for PYLARIFY is expected to expire on December 31, 2024. After TPT Status expires, under current Medicare rules, PYLARIFY would not be separately reimbursed in the hospital outpatient setting but rather would be bundled into the facility payment a hospital receives for a PET/CT imaging procedure, and the uncertaintyfacility payment may not always adequately cover the total cost of third party coveragethe procedure. We can give no assurance that any CMS reimbursement in the hospital outpatient setting that follows the expiration of TPT Status will be adequate to cover the cost of a PYLARIFY PET/CT imaging procedure. In addition, if other government payors or private payors do not provide adequate reimbursement for the use of PYLARIFY, our business, results of operations, financial condition and cash flows could be adversely affected. We plan to continue our advocacy efforts with CMS and private insurers so that PYLARIFY customers will have appropriate and adequate reimbursement rates.following the expiration of TPT Status and we are also supporting trade associations in their efforts to have Congress pass the Facilitating Innovative Nuclear Diagnostics (FIND) Act, which would allow for separate payment for certain diagnostic radiopharmaceuticals, including PYLARIFY, similar to the way Medicare OPPS currently pays for other drugs, biologics, and therapeutic radiopharmaceuticals instead of under the current TPT structure of a separate payment that is limited to three years, however, we can give no assurances that we will be successful in those efforts or that the availability of TPT Status for other diagnostic radiopharmaceuticals will not impact clinical decision making regarding which product to use, which could have an adverse effect on our business, results of operations, financial condition and cash flows.
The successful growth of PYLARIFY is also dependent on our ability to clinically and commercially differentiate PYLARIFY from other products on the market and to maintain PYLARIFY as the leading PSMA PET imaging agent in a competitive environment in which other PSMA PET imaging agents have been approved. PYLARIFY currently competes with two commercially available Ga-68-based PSMA PET imaging agents from Telix Pharmaceuticals Limited and Novartis AG and an F 18 PSMA PET imaging agent from Blue Earth, as well as other non-PSMA PET imaging agents. To the extent we lose market share to existing or future competitors (including during any period of time in which our TPT Status has expired but TPT Status for a later-approved competitive products still exists), such loss of market share could have an adverse impact on our business, results of operations, financial condition and cash flows. Continued growth and revenue contribution from PYLARIFY will also depend on our ability to differentiate

Uncertainties regardingPYLARIFY in light of the impactpotential loss of U.S.TPT Status, including through flexible and state healthcare reform measuresdependable access to PYLARIFY nationally, a best in class customer experience and proposalsthrough long-term strategic contracts.
Our success in growing PYLARIFY also depends, in part, on our successfully establishing the use of PYLARIFY for approved indications and potentially for additional indications, including for patient selection for PSMA-targeted therapeutics. For example, we believe the approval of PLUVICTO for the treatment of adult patients with PSMA-positive mCRPC who have already been treated with other anticancer treatments (androgen receptor pathway inhibition and taxane-based chemotherapy) created a new addressable market for the use of PSMA PET imaging in patient selection for PSMA-targeted therapy. However, the prescribing information for PLUVICTO specifies that a PSMA-11 based PSMA PET imaging agent be used for patient selection, and PYLARIFY is not a PSMA-11 based imaging agent. While we note that FDA-approved labels for F 18-based and PSMA-11 based PSMA PET imaging agents have generally been treated as a class of drugs, including by the National Comprehensive Cancer Center in its guidelines and the Society for Nuclear Medicine and Molecular Imaging in its appropriate use criteria, we can give no assurances that PLUVICTO prescribing information will be expanded to incorporate F 18-based PSMA PET imaging agents like PYLARIFY, or how clinical practice may evolve. To the extent we are unsuccessful in establishing the use of PYLARIFY for approved or new indications, such lack of success could have an adverse impact on our business, including measures and proposals related to reimbursement for our current and potential future products, controls over drug pricing, drug pricing transparency and generic drug competition.
Our being subject to extensive government regulation and oversight, our ability to comply with those regulations and the costsresults of compliance.
Risks Related to our Business Operations and Financial Results
The impact of the ongoing global COVID-19 pandemic on our business,operations, financial condition or prospects, including: a decline in the volume of procedures and treatments using our products; potential delays and disruptions to global supply chains, manufacturing activities, logistics, operations, and clinical development programs; the business activities of our suppliers, distributors, customers and other business partners; the difficulty in recruiting and retaining employees and contractors; and the effects on worldwide economies, financial markets, social institutions, labor markets and healthcare systems.
Our ability to hire or retain the number of qualified personnel, particularly scientific, medical and sales personnel, required for our business.
Our ability to introduce new products and adapt to an evolving technology and medical practice landscape.
Risks associated with our investment in and operation of our specialized manufacturing facility at our North Billerica, Massachusetts campus.
Risks Related to Our Portfolio of Clinical Development Candidates
Risks associated with flurpiridaz F 18, which we out-licensed to GE Healthcare in 2017, including GE Healthcare’s ability to (A) successfully complete the Phase 3 development program, including delays in enrollment that have resulted from the COVID-19 pandemic, (B) obtain FDA approval, and (C) gain post-approval market acceptance and adequate coding, coverage and payment.
Risks associated with 1095, including delays in enrollment that have resulted from the COVID-19 pandemic and our ability to successfully complete the Phase 2 study in mCRPC.
Risks associated with our clinical development candidate LMI 1195
Risks Related to our Capital Structure
Risks related to our outstanding indebtedness and our ability to satisfy those obligations.
Risks related to the ownership of our common stock.

Risks Related to Our Portfolio of Commercial Productscash flows.
The near-term growth of our business is substantiallyalso dependent on our ability to continue to grow the appropriate use of DEFINITY in suboptimal echocardiograms in the face of increased segment competition from other existing echocardiography agents and potential generic competitors.competitors as a result of patent and regulatory exclusivity expirations.
The growth of our business is substantiallyalso dependent on our ability to continue to grow the appropriate use of DEFINITY in suboptimal echocardiograms. DEFINITY currently competes with Optison, aultrasound enhancing agents produced by GE Healthcare product, Lumason, aand Bracco, product, as well as echocardiography without ultrasound enhancing agents and other non-echocardiography agents.
We launched DEFINITY in 2001, and we continue to actively pursue additional patents in connection with DEFINITY and DEFINITY RT, both in the U.S. and internationally. In the U.S. for DEFINITY we have foursix Orange Book-listed method of usemethod-of-use patents, one of which expires in 2035 and threefive of which expire in 2037, as well as additional manufacturing patents that are not Orange Book-listed expiring in 2021, 2023 and 2037. In the U.S. for DEFINITY RT, which became commercially available in the fourth quarter of 2021, we have fiveeight Orange Book-listed patents, including atwo composition of matter patent which expirespatents that expire in 2035. Outside of the U.S., we are currently pursuing additional DEFINITY and DEFINITY RT patents to obtain similar patent protection as in the U.S. The Orange Book-listed patents include a patent on the use of VIALMIX RFID, which expires in 2037; additional VIALMIX RFID patent applications have been submitted in major markets throughout the world.
Because our Orange Book-listed composition of matter patent expired in June 2019, we may face generic DEFINITY challengers in the near to intermediate term. Under the Hatch-Waxman Act, the FDA can approve ANDAs for generic versions of drugs before the expiration of an Orange Book-listed patent covering the innovator product if the ANDA applicant demonstrates,

among other things, that (i) its generic candidate is the same as the innovator product by establishing bioequivalence and providing relevant chemistry, manufacturing and product data, and (ii) either the marketing of that generic candidate does not infringe the Orange Book-listed patent(s) or the Orange Book-listed patent(s) is invalid. Similarly, the FDA can approve a Section 505(b)(2) NDA from an applicant that relies on some of the information required for marketing approval to come from studies which the applicant does not own or have a legal right of reference. The ANDA applicant or the Section 505(b)(2) applicant (if relying on studies related to the innovator product) (together, the “Applicant”) must also give Notice to the innovator, which would then enable the innovator to file suit against the Applicant within 45 days of receiving the Notice. If the innovator challenges the Applicant in court in a timely manner, then FDA approval to commercialize the generic candidate will be stayed (that is, delayed) for up to 30 months while the dispute between the innovator and the Applicant is resolved in court. The 30 month stay can be shortened if the patent infringement suit is resolved in the Applicant’s favor before the 30 month stay expires, and this may involve a successful challenge of the patent’s validity in U.S. Patent and Trademark Office (“USPTO”) proceedings and appeals process. In the event a 505(b)(2) applicant does not rely on studies related to the innovator product, the 30-month stay would not apply, but additional clinical studiestrials may be required. We can give no assurance that we would have grounds to file a patent infringement suit, that we would obtain the full 30 month stay, that we would be successful on the merits asserting that an Applicant infringes our Orange Book-listed patent, or that we would be successful defending the validity of our Orange Book-listed patent in court or in a USPTO adversarial proceeding.
As of the date of filing of this Annual Report on Form 10-K, we have not received any such Notice from any Applicant, but we can give no assurance that we will not receive a Notice in the future. If we were to receive any such Notice in the future, we would review the Notice, evaluate the strength of any potential patent infringement claims, and be prepared to challenge the Applicant in a timely fashion, which would thereby trigger the stay of up to 30 months. We can give no assurance that we would have grounds to file a patent infringement suit, that we would obtain the full 30 month stay, that we would be successful on the merits asserting that an Applicant infringes our Orange Book-listed patent, or that we would be successful defending the validity of our Orange Book-listed patent in court or in a USPTO adversarial proceeding. In addition, as discussed in our risk factor “Our businessIf we were to receive such a Notice and industry are subject to challenge the Applicant, patent litigation is complex and costly regulations. If government regulations are interpreted or enforced incan be protracted and expensive, which could also have a manner adverse to us ornegative effect on our business, we may be subject to enforcement actions, penalties, exclusionresults of operations and other material limitations on our operations.” set forth below, if the FDA reclassified one or morefinancial condition.

Table of our imaging agents, such as DEFINITY, as a “device” rather than a “drug”, we do not know when such reclassification would become effective, how any transition rules would be formulated or applied, and whether or not the legal framework provided by the Hatch-Waxman Act would be preserved for some time after such reclassification.Contents

As part of our microbubble franchise strategy, (i) we have developed and received FDA approval for DEFINITY RT, a modified formulation of DEFINITY, (ii) we look for other opportunities to expand our microbubble franchise, including new applications beyond echocardiography and ultrasound enhancing agent imaging generally such as our strategic arrangements with Cerevast, CarThera, Insightec, AHN and AHN,SonoThera, and (iii) we have constructed a specialized in-house manufacturing facility at our North Billerica campus for purposes of producing the formulation of DEFINITY that requires refrigerated storage and, potentially, other sterile vial products. On February 22, 2022, we received FDA approval of our sNDA, authorizing commericalcommercial manufacturing of DEFINITY at our new facility. However, we can give no assurance that our microbubble franchise strategy will be successful or that the modified formulation, new applications or new manufacturing capabilities will grow our microbubble franchise.
If we are not able to continue to (i) grow DEFINITY and DEFINITY RT sales, which depend on one or more of the growth of echocardiograms, the growth in the appropriate use of ultrasound enhancing agents in suboptimal echocardiograms, and our ability to sustain and grow our leading position in the U.S. echocardiography ultrasound enhancing agent market, or (ii) be successful with our microbubble franchise strategy, we may not be able to continue to grow the revenue and cash flow of our business, which could have a negative effect on our business, results of operations and financial condition.
Our dependence upon third parties for the manufacture and supply of a substantial portion of our products and certain key components and raw materials and upon our in-house manufacturing for DEFINITY could prevent us from delivering our products to our customers in the required quantities, within the required timeframes, or at all, which could result in order cancellations and decreased revenues.
We obtain a substantial portion of our products from third party manufacturers and suppliers. We rely on JHS as a substantial supplier of DEFINITY, as well as our sole source manufacturer of NEUROLITE, Cardiolite and evacuation vials. We rely on SBL as our sole source manufacturer of DEFINITY RT. We rely on various other sole source suppliers for some of our key components and raw materials.
Based on our current estimates, we believe that we will have sufficient supply of DEFINITY, NEUROLITE, Cardiolite and evacuation vials from JHS (together with DEFINITY from our in-house manufacturing facility), and sufficient supply of saline from our sole manufacturer, to meet expected demand. However, we can give no assurances that JHS or our other manufacturing partner will be able to manufacture and distribute our products in a high quality and timely manner and in sufficient quantities to allow us to avoid product stock-outs and shortfalls.

PYLARIFY is manufactured by a nationwide network of PMFs with radioisotope-producing cyclotrons. The radioisotope in PYLARIFY is fluorine-18, which has a 110-minute half-life, so PYLARIFY is manufactured and distributed rapidly to end-users. Because each of the PMFs manufacturing PLYARIFY is deemed by the FDA to be a separate manufacturing site, each has to be separately approved by the FDA. Although we have qualified and continue to qualify additional PMFs, we can give no assurance that the FDA will continue to approve PMFs in accordance with our planned roll-out schedule or that the PMFs will not experience issues with their ability to manufacture and deliver PYLARIFY to our customers. If FDA approval of manufacturing sites is delayed or withdrawn or our PMF sites experience manufacturing issues, our future business, results of operations, financial condition and cash flows could be adversely affected.
Xenon is capturedWe rely on JHS as a by-productsubstantial supplier of the Mo-99 production process.DEFINITY, as well as our sole source manufacturer of NEUROLITE, CARDIOLITE and evacuation vials. We receive bulk unprocessed Xenon from IRE resulting from highly-enriched uranium (“HEU”) Mo-99 production, which we process and finish for our customers. We do not yet receive Xenon resulting from low-enriched uranium (“LEU”) Mo-99 production at IRE and can give no assurances as to the timing of the availability of LEU Xenon. We believe we will have a sufficient supply of Xenon to meet our customers’ needs. However, until IRE converts to LEU Xenon production or we can qualify an additional source of bulk unprocessed Xenon, we will rely on IRESamsung Biologics Co., Ltd.

Until December 2019, the CPDC was subject to an Import Alert by the FDA, which restricted the CPDC’s ability to ship products to the U.S. Although the CPDC has since been cleared by the FDA to ship products to the U.S., there can be no guarantee that the CPDC, or any other ex-U.S. third party manufacturer that we may partner with in the future, will not be subject to similar restrictions in the future.
DEFINITY RT. In addition, to the products described above, for reasons of quality assurance or cost-effectiveness, we purchase certain components and raw materials from sole suppliers (including, for example, the lipid blend material and perflutren gas used in the manufacturing of DEFINITY, the specially designed chemistry synthesis boxes and consumables used in the manufacturing of PYLARIFY, the lipid blend material and perflutren gas used in the manufacturing of DEFINITY and the lead casing for our TechneLite generators). Because we do not control the actual production of many of the products we sell and many of the raw materials and components that make up the products we sell, we may be subject to delays caused by interruption in production based on events and conditions outside of our control.
If we or one of our manufacturing partners or suppliers experiences an event, including a supply chain disruption, shortage or delay, logistics issue, labor dispute, natural disaster, fire, power outage, machinery breakdown, security problem, failure to meet regulatory requirements, product quality issue, technology transfer issue, cybersecurity breach or other issue, we or one of our manufacturing partners or suppliers may be unable to manufacture the relevant products at previous levels or on the forecasted schedule, if at all. Due to the stringent regulations and requirements of the governing regulatory authorities regarding the manufacture of our products, we may not be able to quickly restart manufacturing at a third party or our own facility or establish additional or replacement sources for certain products, components or materials.
In addition to our existing manufacturing relationships, we are also pursuing new manufacturing relationships to establish and secure additional or alternative suppliers for our commercial products. We have also constructed a specialized in-house manufacturing facility at our North Billerica, Massachusetts campus for purposes of producing the formulation of DEFINITY that requires refrigerated storage and, potentially, other sterile vial products. On February 22, 2022, we received FDA approval of our sNDA, authorizing commercial manufacturing of DEFINITY at our new facility. This project should deliverprovides a certain amount of supply chain redundancy for our current portfolio and the opportunity for margin expansion.DEFINITY (other than DEFINITY RT, which is supplied solely by SBL). However, we cannot assure you that these activities or any of our additional supply activities will be successful or that we will be able to avoid or mitigate interim supply shortages before new sources of product are fully functional and qualified. In addition, we cannot assure you that our existing manufacturers or suppliers or any new manufacturers or suppliers can adequately maintain either their financial health, technical capabilities or regulatory compliance to allow continued production and supply. A reduction or interruption in manufacturing, or an inability to secure alternative sources of raw materials or components, could eventually have a material adverse effect on our business, results of operations, financial condition and cash flows.

The global supply of Mo-99 is fragile and not stable. Our dependence on a limited number of third party suppliers for Mo-99 could prevent us from delivering some of our products to our customers in the required quantities, within the required timeframe, or at all, which could result in order cancellations and decreased revenues.
A critical ingredient of TechneLite is Mo-99. We currently purchase finished Mo-99 from three of the four main processing sites in the world, namely IRE in Belgium, NTP in South Africa and ANSTO in Australia. These processing sites provide us Mo-99 from five of the six main Mo-99-producing reactors in the world, namely BR2 in Belgium, LVR-15 in the Czech Republic, HFR in The Netherlands, SAFARI in South Africa and OPAL in Australia.
Our agreement with NTP, acting for itself and on behalf of its subcontractor ANSTO, expires on MarchDecember 31, 2022. We are actively negotiating2024.
Although we have a newglobally diverse Mo-99 supply agreement with IRE in Belgium, NTP althoughin South Africa, and ANSTO in Australia, we can give no assurance that we will be able to reach an agreement on mutually acceptable terms or at all. In the event we are not able to enter into an agreement on mutually acceptable terms or at all,

we would expect to attempt to increase our purchases of Mo-99 from IREstill face supplier and enter into a direct arrangement with ANSTO, but we can give no assurance that we would be able to increase our purchases from IRE or directly purchase from ANSTO or that there would be no disruptionlogistical challenges in our ability to fill some or all of the demand for our TechneLite generators on certain manufacturing days.
The NTP processing facility had periodicMo-99 supply chain. When one supplier experiences outages, in 2017, 2018 and 2019. When NTP was not producing, we reliedgenerally rely on Mo-99 supply from both IRE and ANSTOthe other suppliers to limit the impact of the NTP outages. In 2019 and 2020, ANSTO experienced multiple facility issues that resulted in ANSTO outages and volume limitations, during which timeWe believe we relied on IRE and NTP to limit the impact of those outages and limitations. Because of the COVID-19 pandemic, we experienced challenges receiving regularly scheduled orders of Mo-99 from our global suppliers, particularly in the second quarter of 2020. We continue toeffectively manage these various supply chain challenges, but depending on reactor and processor schedules and operations, at times we have not been able to fill some or all of the demand for our TechneLite generators on certain manufacturing days. A prolonged disruption of service from one of our three Mo-99 processing sites or one of their main Mo-99-producing reactors could have a substantial negative effect on our business, results of operations, financial condition and cash flows.
To augment our current supply of Mo-99, we entered into a strategic arrangement with SHINE for the future supply of Mo-99. Under the terms of the supply agreement, entered into in November 2014, SHINE will provide Mo-99 produced using its proprietary LEU-solution technology for use in our TechneLite generators once SHINE’s facility becomes operational and receives all necessary regulatory approvals, which SHINE now estimates will occur in 2023. The term of this arrangement provides for three years of supply of Mo-99. However, we cannot assure you that our arrangement with SHINE will result in commercial quantities of Mo-99 for our business, or that SHINE together with our current suppliers will be able to deliver a sufficient quantity of Mo-99 to meet our needs.
U.S., Canadian and international governments have encouraged the development of a number of alternative Mo-99 production projects with existing reactors and technologies as well as new technologies. However, we cannot say when, or if, the Mo-99 produced from these projects will become available. As a result, there is a limited amount of Mo-99 available which could limit the quantity of TechneLite that we could manufacture, sell and distribute, resulting in a further substantial negative effect on our business, results of operations, financial condition and cash flows.
Most of the global suppliers of Mo-99 rely on Framatone-CERCA in France to fabricate uranium targets and in some cases fuel for research reactors from which Mo-99 is produced. Absent a new supplier, a supply disruption relating to uranium targets or fuel could have a substantial negative effect on our business, results of operations, financial condition and cash flows.
Our ability to successfully launch PYLARIFY as a commercial product is dependent on (A) our ability to obtain FDA approval for additional PMFs that could manufacture PYLARIFY, (B) the ability of those PMFs to supply PYLARIFY to customers, (C) our ability to sell PYLARIFY to customers, and (D) our ability to obtain and maintain adequate coding, coverage and payment for PYLARIFY.
The commercial launch of PYLARIFY is complex and expensive. To manufacture PYLARIFY, we assembled and qualified a nationwide network of PMFs with radioisotope-producing cyclotrons that make F 18, which has a 110-minute half-life, so PYLARIFY is manufactured and distributed rapidly to end-users. Because each of the PMFs manufacturing these products is deemed by the FDA to be a separate manufacturing site, each has to be separately approved by the FDA. Although we successfully qualified 21 PMFs in 2021 and continue to qualify additional PMFs in 2022, such that PYLARIFY is broadly available across the U.S. (including through our efforts to fly doses to certain markets ahead of PMF activation), weWe can give no assurance that the FDACurium will continue to approve PMFs in accordancebe successful with our planned roll-out schedule. If FDA approval of manufacturing sites is delayed or withdrawn, our future business, results of operations, financial condition and cash flows could be adversely affected.
PYLARIFY is sold in the U.S. to hospitals, independent imaging centers and government facilities and are generated through a PYLARIFY direct sales team and a sales team at some of our PMF partners. We generally do not use group purchasing arrangements to sell PYLARIFY and require contracts to be entered into directly with each customer. During 2021, we hired additional employees to assist us with thisits commercialization of PYLARIFY. Ourpiflufolastat F 18 in Europe.
We have licensed exclusive rights to Curium to develop and commercialize piflufolastat F 18 in Europe. Under the terms of the collaboration, Curium is responsible for the development, regulatory approvals and commercialization of piflufolastat F 18 in Europe, and we are entitled to double-digit royalties on net sales of piflufolastat F 18. In July 2023, Curium announced that the EMA approved piflufolastat F 18 in Europe, under the name PYLCLARI. We cannot assure that Curium will be successful in commercializing it in Europe. Any failure or significant delay in Curium’s ability to continue to successfully launch PYLARIFY depends,PYLCLARI in part, onEurope may harm our ability to continue to enter into arrangements directly with the hospitals, independent imaging centersbusiness and government facilities that we serve. Any delay or inabilityprevent us from being able to enter into these arrangements could have an adverse impact on ourgenerate additional future business, results of operations, financial condition and cash flows.
In addition, obtaining adequate coding, coverage and payment for PYLARIFY is critical, including not only coverageroyalty revenue from Medicare, Medicaid and other government payors, as well as private payors, but also appropriate payment levels to adequately cover our customers’ costs of using PYLARIFY in PET/CT imaging procedures. We received notification that our HCPCS code, which enables streamlined billing, went into effect as of January 1, 2022. In addition, effective January 1, 2022, CMS granted Transitional Pass-Through Payment Status for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in the hospital outpatient setting. If other government payors or private payors do not provide adequate

reimbursement for the use of PYLARIFY, our future business, results of operations, financial condition and cash flows could be adversely affected.
The successful launch of PYLARIFY is also dependent on our ability to establish PYLARIFY as a leading PET diagnostic for men with prostate cancer in the approved indications. PYLARIFY currently competes with Telix Pharmaceuticals Limited’s recently-approved Illuccix (gallium-68 PSMA-11 injection) and Bracco’s Axumin (fluciclovine F 18). We also face potential competition from Novartis AG, which has a gallium-68 PSMA-11 kit for PET imaging currently under review with the FDA, and Bracco, which has an F 18 PSMA PET imaging agent in late stage clinical development. We believe that one or both of the Novartis and Bracco PSMA agents could be approved by the FDA for commercialization later in 2022 or in 2023. To the extent we are unsuccessful in establishing the use of PYLARIFY for approved indications or we lose market share to existing or future competitors, such lack of success or loss of market share could have an adverse impact on our future business, results of operations, financial condition and cash flows. In addition, because we are in the process of launching this imaging agent, we can give no assurance as to how clinical practice may evolve or what our ultimate market penetration may be.product sales.
We may not be able to successfully launch PYLARIFY AI as a commercial product.
We announced in November 2021 that PYLARIFY AI, our FDA-cleared medical device software, was commercially available in the United States. Our ability to successfully launch PYLARIFY AI as a commercial product depends in part on, among other things:
the market receptivity to PYLARIFY AI as a new digital application for quantitative assessment of PSMA PET/CT images in prostate cancer;
our ability, and our distributors’ abilities, to secure customers’ internal approvals and sell and deploy PYLARIFY AI at customer locations;
interruptions or performance problems associated with our digital application, including a service outage; and
a network or data security incident that allows unauthorized access to our network or data or our customers’ data.
Although we believe that PYLARIFY AI when used with PYLARIFY will provide us an important competitive advantage in what we expect will be a highly competitive PET PSMA diagnostic imaging agent market, we can give no assurances to that effect.
We rely on Bausch to develop and commercialize RELISTOR, exposing us to significant risks.
We rely on Bausch to pursue and complete further development and obtain regulatory approvals for RELISTOR worldwide and to effectively commercialize the product and manage pricing, sales and marketing practices and inventory levels in the distribution channel. The revenue derived from royalty and milestone payments from our RELISTOR collaboration with Bausch can fluctuate significantly from period to period, and our past revenue is therefore not necessarily indicative of our future revenue. We are and will be dependent upon Bausch and any other business partners with which we may collaborate in the future to perform and fund development, including clinical testing of RELISTOR, making related regulatory filings and manufacturing and marketing products, including for new indications and in new formulations, in their respective territories. Revenue from the sale of RELISTOR depends entirely upon the efforts of Bausch and its sublicensees, which have significant discretion in determining the efforts and resources they apply to sales of RELISTOR. Bausch may not be effective in obtaining approvals for new indications or formulations, marketing existing or future products or arranging for necessary sublicense or distribution relationships. Our business relationships with Bausch and other partners may not be scientifically, clinically or commercially successful. For example, Bausch has a variety of marketed products and its own corporate objectives, which may not be consistent with our best interests, and may change its strategic focus or pursue alternative technologies in a manner that results in reduced or delayed revenue to us. Bausch may also have commercial and financial interests that are not fully aligned with ours in a given territory or territories, which may make it more difficult for us to fully realize the value of RELISTOR. We may have future disagreements with Bausch, which has significantly greater financial and managerial resources which it could draw upon in the event of a dispute. Such disagreements could lead to lengthy and expensive litigation or other dispute-resolution proceedings as well as extensive financial and operational consequences to us and have an adverse effect on our business, results of operations and financial condition. In addition, independent actions may be taken by Bausch concerning product development, marketing strategies, manufacturing and supply issues, and rights relating to intellectual property.
We are also dependent on Bausch for compliance with regulatory requirements as they apply to RELISTOR.
The RELISTOR commercialization program continues to be subject to risk.
Future developments in the commercialization of RELISTOR may result in Bausch taking independent actions concerning product development, marketing strategies or other matters, including termination of its efforts to develop and commercialize the drug.
33

Table of Contents

Under our license agreement with Bausch, Bausch is responsible for obtaining supplies of RELISTOR, including contracting with contract manufacturing organizations (“CMOs”) for supply of RELISTOR active pharmaceutical ingredient and subcutaneous and oral finished drug product. These arrangements may not be on terms that are advantageous and will subject us to risks that the counterparties may not perform optimally in terms of quality or reliability.
Bausch’s ability to optimally commercialize either oral or subcutaneous RELISTOR in a given jurisdiction may be impacted by applicable labeling and other regulatory requirements. If clinical trials indicate, or regulatory bodies are concerned about, actual or possible serious problems with the safety or efficacy of RELISTOR, Bausch may stop or significantly slow further development or commercialization of RELISTOR. In such an event, we could be faced with either further developing and commercializing the drug on our own or with one or more substitute collaborators, either of which paths would subject us to the development, commercialization, collaboration and/or financing risks.
There has been growing public concern regarding the use of opioid drugs. Any efforts by the FDA or other governmental authorities to restrict or limit the use of opioids may negatively impact the market for RELISTOR. In addition, there is a substantial risk that the revenue targets for receiving additional RELISTOR milestone payments will not be met. As a result, there is no assurance that we will realize the potential revenue represented by future RELISTOR milestone payments.
Any such significant action adverse to the further development and commercialization of RELISTOR could have an adverse impact on our business.
Our AZEDRA commercialization program is subject to significant risk.
Progenics received FDA approval for AZEDRA in July 2018. Since then, the AZEDRA commercial program has faced numerous challenges, including, among other things:
decisions by treating physicians and patients to defer treatment and by hospital facilities to limit access for our representatives until COVID-19 infection rates subside;
challenges in securing I-131 supply and manufacturing patient-ready doses of AZEDRA;
a small Orphan Drug patient population;
reluctance by some potential hospital customers to invest in the necessary facility build-out to accommodate the administration of a highly radioactive therapeutic agent (including, among other things, the construction of lead-lined rooms to accommodate inpatients following AZEDRA’s administration); and
the high cost of the drug and reimbursement.
Because of these issues, we can give no assurance that AZEDRA will become a commercial success. After increased experience administering AZEDRA, clinicians may conclude that the complexity of administration and/or safety concerns with using a highly radioactive therapeutic agent may not justify AZEDRA’s perceived clinical benefits. AZEDRA became eligible for new technology add-on payments (NTAP) under the Medicare Hospital Inpatient Prospective Payment System (IPPS) effective October 1, 2019. As required by statute, NTAP eligibility under the IPPS can continue for a period of at least two years, but not more than three years. Under the fiscal year 2022 IPPS Final Rule, published in September 2021, CMS finalized continuation of AZEDRA’s NTAP for fiscal year 2022—i.e., from October 1, 2021 through September 30, 2022. AZEDRA’s NTAP will most likely expire September 30, 2022. If post-pass-through payment levels impact market acceptance for AZEDRA, the drug may not generate enough revenue to make it economically viable. In addition, the market may react negatively to the high cost of AZEDRA, which could result in negative publicity and potentially reputational harm to us. Further, to the extent new Federal restrictions relating to drug pricing are implemented and apply to AZEDRA, the additional pricing pressure could further limit AZEDRA’s economic viability.
If AZEDRA is determined to be challenging to administer, not economically viable or we are unable to successfully commercialize it, our business, results of operations, financial condition and cash flows could be adversely affected.
We may not be able to maintain Orphan Drug exclusivity for AZEDRA and, even if we do, that exclusivity may not prevent the FDA, from approving competing products.
Under the Orphan Drug Act, the FDA may designate a product as an Orphan Drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States. AZEDRA currently has the Orphan Drug designation in the United States.
In the United States, Orphan Drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers. In addition, if a product that has Orphan Drug designation
34

Table of Contents

subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to Orphan Drug exclusivity, which means the FDA may not approve any other application to market the same drug for the same indication for a period of seven years, except in limited circumstances, such as a showing of clinical superiority over the product with orphan exclusivity or where the manufacturer is unable to assure sufficient product quantity.
We may not be able to maintain Orphan Drug exclusivity for AZEDRA. In addition, exclusive marketing rights in the United States may be limited if we seek approval for an indication broader than the orphan-designated indication or may be lost if the FDA later determines that the request for designation was materially defective or if we are unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Even after an Orphan Drug is approved, the FDA can subsequently approve the same drug with the same active moiety for the same condition if the FDA concludes that the later drug is safer, more effective or makes a major contribution to patient care. A loss of the Orphan Drug exclusivity for AZEDRA may have an adverse impact on our ability to adequately commercialize AZEDRA.
Our just-in-time manufacturing of radiopharmaceutical products relies on the reliability of our equipment and processes, and the timely receipt of radioactive raw materials and the timely shipment of finished goods, and any disruption of our supply or distribution networks could have a negative effect on our business.
At the facility on our North Billerica, Massachusetts facility,campus, we manufacture TechneLite on a highlyan automated production line, as well as Thallium and Gallium using our older cyclotron technology and Xenon on a hot cell line. At our Somerset, New Jersey facility, we manufacture AZEDRA on a hot cell line. As with all manufacturing facilities, equipment and infrastructure age and become subject to increasing maintenance and repair. If we experience an event, including a labor dispute, natural disaster, fire, power outage, machinery breakdown, security problem, failure to meet regulatory requirements, product quality issue, technology transfer issue or other issue, we may be unable to manufacture the relevant products at previous levels or on the forecasted schedule, if at all. Due to the stringent regulations and requirements of the
32

Table of Contents

governing regulatory authorities regarding the manufacture of our products, we may not be able to quickly restart manufacturing at our facilities or establish additional or replacement sources for certain products, components or materials.
In addition, because a number of our radiopharmaceutical products, including PYLARIFY and our TechneLite generators PYLARIFY and AZEDRA, rely on radioisotopes with limited half-lives, we or our partners must manufacture, finish and distribute these products on a just-in-time basis, because the underlying radioisotope is in a constant state of decay. For example, if we receive Mo-99 in the morning of a manufacturing day for TechneLite generators, then we will generally ship finished generators to customers by the end of that same business day. Shipment of generators may be by next day delivery services or by either ground or air custom logistics. Similarly, the radioisotope used in PYLARIFY is F 18, which has a 110 minute half-life, requiring that this product be manufactured and distributed within the same day to end-users. After being made on a cyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to a radiopharmacist who prepares and dispenses patient-specific doses from the final product. Similarly, with respect to our TechneLite generators, if we receive Mo-99 in the morning of a manufacturing day for TechneLite generators, then we will generally ship finished generators to customers by the end of that same business day. Shipment of generators may be by next day delivery services or by either ground or air custom logistics. Any delay in us receiving radioisotopes from suppliers or being able to have finished products delivered to customers because of weather or other unforeseen transportation issues could have a negative effect on our business, results of operations, financial condition and cash flows.
In the U.S., we are heavily dependent on a few large customers to generate a majority of our revenues for our single-photon emission computerized tomography (SPECT) nuclear medical imaging products in our precision diagnosticPrecision Diagnostic product category. For PYLARIFY, we depend in part on some of our PMF partners to generate sales and collect revenue. Outside of the U.S., we rely primarily on distributors to generate a substantial portion of our revenue.
In the U.S., we have historically relied on a limited number of radiopharmacy customers, primarily Cardinal, RLS, UPPI, PharmaLogic and Jubilant Radiopharma, PharmaLogic, RLS and UPPI, to purchase our current largest volume nuclear imaging products.products in our Precision Diagnostic product category. Among the existing radiopharmacies in the U.S., continued consolidations, divestitures and reorganizations may have a negative effect on our business, results of operations, financial condition and cash flows. Our contractual arrangements with these radiopharmacy customers generally specify pricing levels and requirements to purchase minimum percentages of certain products during certain periods. The agreements generally are multi-year arrangements that may be terminated upon the occurrence of specified events, including a material breach by the other party and certain force majeure events. If these contracts are terminated prior to the expiration of their term, or are not renewed, or are renewed on terms that are less favorable to us, then such an event could have a material adverse effect on our business, results of operations, financial condition and cash flows.
For allPYLARIFY, we depend in part on some of our medical imaging products, wePMF partners to generate sales and collect revenue. To the extent our PMF partners are unsuccessful in generating sales or in collecting revenue, such an event could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We also continue to experience significant pricing pressures from our competitors, large customers and group purchasing organizations, and any significant, additional pricing pressures could lead to a reduction in revenue which could have a material adverse effect on our business, results of operations, financial condition and cash flows.

Outside of the U.S. and Canada,, we have no sales force and, consequently, rely on third party distributors, either on a country-by-country basis or on a multi-country, regional basis, to market, sell and distribute our products. In Canada, we maintain our own direct sales force to generate sales of DEFINITY. In certain circumstances, distributors may also sell competing products to our own or products for competing diagnostic modalities and may have incentives to shift sales towards those competing products. As a result, we cannot assure you that our international distributors will increase or maintain current levels of unit sales or that we will be able to increase or maintain our current unit pricing, which, in turn, could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We face significant competition in our business and may not be able to compete effectively.
The markets for our products are highly competitive and continually evolving. Our principal competitors for our current commercial products and leading clinical development candidates include large, global companies that are more diversified than we are and that have substantial financial, manufacturing, sales and marketing, distribution and other resources:
For PYLARIFY, our competitors currently include approved imaging agents from Telix Pharmaceuticals Limited, Novartis AG, and Blue Earth, a subsidiary of Bracco.
For DEFINITY, our competitors currently include GE Healthcare and Bracco.
For a number of our radiopharmaceutical commercial products, our competitors currently include Curium, GE Healthcare, Bracco and Jubilant Life Sciences, an affiliate of JHS and Jubilant Radiopharma, as well as other competitors, including NorthStar and potentially BWXT Medical.
For PYLARIFY,PNT2002 and 1095, our principal competitors currentlymay include Novartis AG; Telix Pharmaceuticals LimitedLimited; and Bracco, and may in the future include Novartis AG,Curium, each of which has a gallium-68 PSMA-11 kit for PET imaging currently under review with the FDA, and Bracco, which has an F 18 PSMA PET imaging agentcommercialized products or product candidates in lateadvanced clinical stage clinical development; we believe that one or both of the Novartis and Bracco PSMA agents could be approved by the FDA for commercialization later in 2022 or in 2023. In addition, the Universitydevelopment.

We cannot anticipate the actions of our current or future competitors in the same or competing diagnostic modalities, such as significant price reductions on products that are comparable tocompetitive with our own, development of new products that are more cost-effective or have superior performance than our current products or potential future products or the introduction of generic versions after our proprietary products lose their patent protection. In addition, distributors of our products could attempt to shift end-users to competing diagnostic modalities and products, or bundle the sale of a portfolio of products, in either case to the detriment of our specific products. Our current or future products could be rendered obsolete or uneconomical as a result of these activities.
Further, the radiopharmaceutical industry continues to evolve strategically, with several market participants either recently sold or for sale.sold. In addition, the supply-demand dynamics of the industry are complex because of large market positions of some participants, legacy businesses, government subsidies (in particular, relating to the manufacture of radioisotopes), and group purchasing arrangements. We cannot predict what impact new owners and new operators may have on the strategic decision-making of our competitors, customers and suppliers, and such decision-making could have a material adverse effect on our business, results of operations, financial condition and cash flows.
Ultrasound enhancing agents may cause side effects which could limit our ability to sell DEFINITY.
DEFINITY is an ultrasound enhancing agent based on perflutren lipid microspheres. In 2007, the FDA received reports of deaths and serious cardiopulmonary reactions following the administration of ultrasound micro-bubble enhancing agents used in echocardiography. Four of the 11 reported deaths were caused by cardiac arrest occurring either during or within 30 minutes following the administration of the ultrasound enhancing agent; most of the serious but non-fatal reactions also occurred in this time frame. As a result, in October 2007, the FDA requested that we and GE Healthcare, which distributes Optison, a competitor to DEFINITY, add a boxed warning to these products emphasizing the risk for serious cardiopulmonary reactions and that the use of these products was
36

Table of Contents

contraindicated in certain patients. In a strong reaction by the cardiology community to the FDA’s new position, a letter was sent to the FDA, signed by 161 doctors, stating that the benefit of these ultrasound enhancing agents outweighed the risks and urging that the boxed warning be removed. In May 2008, the FDA substantially modified the boxed warning. On May 2, 2011, the FDA held an advisory committee meeting to consider the status of ultrasound micro-bubble contrastenhancing agents and the boxed warning. In October 2011, we received FDA approval of further modifications to the DEFINITY label, including: further relaxing the boxed warning; eliminating the sentence in the Indication and Use section “The safety and efficacy of DEFINITY with exercise stress or pharmacologic stress testing have not been established” (previously added in October 2007 in connection with the imposition of the box warning); and including summary data from the post-approval CaRES (Contrast echocardiography Registry for Safety Surveillance) safety registry and the post-approval pulmonary hypertension study. Further, in January 2017, the FDA approved an additional modification to the DEFINITY label, removing the contraindication statement related to use in patients with a known or suspected cardiac shunt. Bracco’s ultrasound enhancing agent, Lumason, has substantially similar safety labeling as DEFINITY and Optison. In April 2021, after reviewing certain adverse events that occurred in patients with a prior history of allergic reactions to polyethylene glycol (“PEG”), an inactive excipient in both DEFINITY and Lumason, the FDA and the marketing authorization holders of these products agreed to an additional contraindication for use of these products, including advising clinicians to assess patients for prior PEG hypersensitivity before administering these products. In June 2023, after reviewing adverse events that occurred in patients with history of sickle cell disease, we agreed with the FDA to amend the label to advise clinicians that if a patient with sickle cell disease experiences acute pain episodes following DEFINITY administration, use of DEFINITY in that patient should be discontinued. If additional safety issues arise (not only with DEFINITY but also potentially with Optison and Lumason), this may result in unfavorable changes in labeling or result in restrictions on the approval of our product, including removal of the product from the market. Lingering safety concerns about DEFINITY among some healthcare providers or future unanticipated side effects or safety concerns associated with DEFINITY could limit expanded use of DEFINITY and have a material adverse effect on the unit sales of this product and our financial condition and results of operations.

Many of our customers are highly dependent on payments from third partythird-party payors, including government sponsored programs, particularly Medicare, in the U.S. and other countries in which we operate, and reductions in third party coverage and reimbursement rates for our products (or services provided with our products) could adversely affect our business and results of operations.
A substantial portion of our revenue depends on the extent to which the costs of our products purchased by our customers (or services provided with our products) are reimbursed by third party payors, including Medicare, Medicaid, other U.S. government sponsored programs, non-U.S. governmental payors and private payors. These third partythird-party payors exercise significant control over patient access and increasingly use their enhanced bargaining power to secure discounted rates and impose other requirements that may reduce demand for our products. Our customers’ ability to obtain adequate reimbursement for products and services from these third partythird-party payors affects the selection of products they purchase and the prices they are willing to pay. If Medicare and other third party payors do not provide adequate reimbursement for the costs of our products (or services provided using our products), deny the coverage of the products (or those services), or reduce current levels of reimbursement, healthcare professionals may not prescribe our products and providers and suppliers may not purchase our products.
In addition, demand for new products may be limited unless we obtain favorable reimbursement (including coding, coverage and payment) from governmental and private third party payors at the time of the product’s introduction, which will depend, in part, on our ability to demonstrate that a new agent has a positive impact on clinical outcomes. Third partyThird-party payors continually review their coverage policies for existing and new products and procedures and can deny coverage for products or procedures that include the use of our products or revise payment policies such that payments do not adequately cover the cost of our products. Even if third partythird-party payors make coverage and reimbursement available, that reimbursement may not be adequate or these payors’ reimbursement policies may have an adverse effect on our business, results of operations, financial condition and cash flows.
For example, effective January 1, 2022, the CMS granted TPT Status in the hospital outpatient setting for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in that setting. TPT Status for PYLARIFY is expected to expire December 31, 2024. After TPT Status expires, under current Medicare rules, PYLARIFY similar to other diagnostic radiopharmaceuticals, would not be separately reimbursed in the hospital outpatient setting but rather would be included as part ofbundled into the facility feepayment a hospital otherwise receives for a PET/CT imaging procedure, and the facility fee doespayment may not always cover the total cost of a drug usedthe procedure. In 2023 rulemaking for the 2024 payment calendar year, CMS recognized the challenges of patient access to diagnostic radiopharmaceuticals and requested feedback on various payment alternatives that could provide separate reimbursement for these items, but the agency did not adopt any of these proposals in the procedure. The Companyfinal rule, while stating that it would continue to evaluate this issue in subsequent rulemaking. We can give no assurance that any CMS reimbursement in the hospital outpatient setting that follows the expiration of TPT Status will be adequate to cover the cost ofa PYLARIFY used in a PET/CT imaging procedure.

TPT Status for other diagnostic radiopharmaceuticals will not impact clinical decision making regarding which product to use, which could have an adverse effect on our business, results of operations, financial condition and cash flows.
Over the past several years, Medicare has implemented numerous changes to payment policies for imaging procedures in both the hospital setting and non-hospital settings (which include physician offices and freestanding imaging facilities). Some of these changes have had a negative impact on utilization of imaging services. Examples of these changes include:
Limiting payments for imaging services in physician offices and free-standing imaging facility settings based upon rates paid to hospital outpatient departments;
Reducing payments for certain imaging procedures when performed together with other imaging procedures in the same family of procedures on the same patient on the same day in the physician office and free-standing imaging facility setting;
Making significant revisions to the methodology for determining the practice expense component of the Medicare payment applicable to the physician office and free-standing imaging facility settings which results in a reduction in payment;
Revising payment policies and reducing payment amounts for imaging procedures performed in the hospital outpatient settings; and
Reducing prospective payment levels for applicable diagnosis-related groups in the hospital inpatient setting.
In the physician office and free-standing imaging facility setting, services provided using our products are reimbursed under the Medicare physician fee schedule. Payment rates under the Medicare physician fee schedule are regularly subject to updates to effectuate various policy goals.goals of CMS and Congress. For example, in 2022, CMS reduced Medicare fee schedule payments rates in the agency’s final rulemaking, while a larger cut was put forth in the proposed rulemaking earlier that year. For 2023, CMS had finalized a reduction in the Medicare fee schedule payments rates, which was revised by Congress, pursuant to the Consolidated Appropriations Act, 2023, to a lesser reduction. Additionally, since 2019, fee schedule payments have been adjusted for certain physicians based on their performance under a consolidated measurement system (that measures performance with respect to quality, resource utilization, meaningful use of certified electronic health records technology, and clinical practice improvement activities).

From 2019 through payment year 2024, physicians may be eligible for a bonus based on the use of certain alternative payment models designated as “advanced” by CMS. The ongoing and future impact of these changes cannot be determined at this time.
We believe that Medicare changes to payment policies for imaging procedures applicable to non-hospital settings will continue to result in certain physician practices ceasing to provide these services and a further shifting of where certain medical imaging procedures are performed, from the physician office and free-standing imaging facility settings to the hospital outpatient setting. Changes applicable to Medicare payment in the hospital outpatient setting could also influence the decisions by hospital outpatient physicians to perform procedures that involve our products. Within the hospital outpatient setting, CMS payment policy is such that the use of many of our products are not separately payable by Medicare, although certain new drug products are eligible for separate (incremental) payment for the first three years after approval. Although Medicare generally does not provide separate payment to hospitals for the use of diagnostic radiopharmaceuticals administered in an outpatient setting, since 2013, CMS has had a policy to make a nominal additional payment ($10) to hospitals that utilize products with non-HEU, meaning the product is 95% derived from non-HEU sources. This payment policy continues in 2022. Although some of our TechneLite generators are manufactured using non-HEU, not all of our TechneLite generators currently meet CMS’s definition of non-HEU, and therefore this payment is not available for doses produced by the latter category of TechneLite generators used by our customers. Changes to the Medicare hospital outpatient prospective payment system payment rates, including reductions implemented for certain hospital outpatient sites, could influence the decisions by hospital outpatient physicians to perform procedures that involve our products.
We also believe that all of these changes and their resulting pressures may incrementally reduce the overall number of diagnostic medical imaging procedures performed. These changes overall could slow the acceptance and introduction of next-generation imaging equipment into the marketplace, which, in turn, could adversely impact the future market adoption of certain of our imaging agents already in the market or currently in development. We expect that there will continue to be proposals to reduce or limit Medicare and Medicaid payment for diagnostic services.services, which could impact our current or potential future diagnostic and other types of products and have a material adverse effect on our business, results of operations, financial condition and cash flows.
We also expect increased regulation and oversight of advanced diagnostic testing in which our products are used.used, although the timing of such regulation is uncertain after a recent pause by CMS. Under section 218(b) of the Protecting Access to Medicare Act, beginning January 1, 2020, a professional who is ordering advanced diagnostic imaging services (which include MRI, CT, nuclear medicine (including PET) and other advanced diagnostic imaging services that the Secretary of HHS may specify, but not currently including echocardiography) must consult a qualified clinical decision support mechanism, as identified by HHS, to determine whether the ordered service adheres to specified appropriate use criteria (“AUC”) developed or endorsed by CMS-qualified “provider led entities”. Medicare claims for such services must include information indicating whether services ordered would adhere to specified applicable AUC. Denial of claims for failure to include AUC consultation information on the claim form was set to begin on January 1, 2022.2022, but was not implemented by CMS. In the CY 20222024 Physician Fee Schedule Final Rule, CMS delayeddetermined that it was not feasible to fully operationalize the start of these claims denials untilAUC program consistent with the later of January 1, 2023, orstatute within the January 1st that followsrequired time frame. Accordingly, the declared endagency finalized an indefinite pause to the AUC program and the recission of the Public Health Emergency for COVID–19. Toregulations promulgated thus far to implement the AUC program. While it is unclear when CMS will resume implementation of the AUC program, to the extent that these types of changes have the effect of reducing the aggregate number of diagnostic medical imaging procedures performed in the U.S., our business, results of operations, financial condition and cash flows would be adversely affected.

Medicare coverage of PET radiopharmaceuticals has been the subject of a large number of National Coverage Determinations (“NCDs”) by CMS since 2000. Specific indications for PET imaging were covered, some through Coverage with Evidence Development. CMS’s longtime policy, however, was that a particular use of PET scans is not covered unless an NCD specifically provided that such use was covered. Effective March 7, 2013, CMS revised its policy through an NCD to allow local Medicare Administrative Contractors (“MACs”) to determine coverage within their respective jurisdictions for PET using radiopharmaceuticals for their FDA-approved labeled indications for oncologic imaging. Effective January 1, 2022, non-coverage in the absence of an NCD has also been removed for non-oncologic indications of PET radiopharmaceuticals, allowing MACs to determine coverage for these indications within their respective jurisdictions. To the extent that CMS or the MACs impose more restrictive coverage, our business, results of operations, financial condition and cash flows would be adversely affected.
Reforms to the U.S. healthcare system may adversely affect our business.
A significant portion of our patient volume is derived from U.S. government healthcare programs, principally Medicare, which are highly regulated and subject to frequent and substantial changes. The Healthcare Reform Act substantially changed the way healthcare is financed by both governmental and private insurers. The law contains a number of provisions that affect coverage and reimbursement of drug products and medical imaging procedures in which our drug products are used and/or that could potentially reduce the aggregate number of diagnostic medical imaging procedures performed in the U.S. Subsequently, the Medicare Access and CHIP Reauthorization Act of 2015 significantly revised the methodology for updating the Medicare physician fee schedule. And more recently,In 2017, Congress enacted legislation in 2017 that effectively eliminated the Healthcare Reform Act’s “individual mandate” beginning in 2019. Congress continues to consider other healthcare reform legislation. There is no assurance that the Healthcare Reform Act, as currently enacted or as amended in the future, will not adversely affect our business and financial results, and we cannot predict how future federal or state legislative, judicial or administrative changes relating to healthcare reform will affect our business.

Table of Contents

In addition, other legislative changes have been proposed and adopted since the Healthcare Reform Act was enacted. The Budget Control Act of 2011 and subsequent Congressional actions includes provisions to reduce the federal deficit. These provisions have resulted in the imposition of 2% reductions in Medicare payments to providers, which went into effect on April 1, 2013 and will remain in effect through fiscal year 2030. The CARES Act temporarily suspendedimposition of the 2% payment adjustment for dates of service from May 1had been suspended through December 31, 2020, the Consolidated Appropriations Act 2021 subsequently extended this suspension until March 31, 2021,2022 and Congress further extended the suspension through March 31,went into effect as of April 1, 2022. Any significant spending reductions affecting Medicare, Medicaid or other publicly funded or subsidized health programs that may be implemented and/or any significant taxes or fees that may be imposed on us, as part of any broader deficit reduction effort or legislative replacement to the Budget Control Act, could have an adverse impact on our business, results of operations, financial condition and cash flows.
Further, changes in payor mix and reimbursement by private third partythird-party payors may also affect our business. Rates paid by some private third partythird-party payors are based, in part, on established physician, clinic and hospital charges and are generally higher than Medicare payment rates. Reductions in the amount of reimbursement paid for diagnostic medical imaging procedures, including the elimination of any additional payment such as TPT Status, and changes in the mix of our patients between non-governmental payors and government sponsored healthcare programs and among different types of non-government payor sources, could have a material adverse effect on our business, results of operations, financial condition and cash flows.
The full impact on our business of healthcare reforms and other new laws, or changes in existing laws, is uncertain. Nor is it clear whether additional legislative changes will be adopted or how those changes would affect our industry in general or our ability to successfully commercialize our products or develop or commercialize new products.
Our business and industry are subject to complex and costly regulations. If government regulations are interpreted or enforced in a manner adverse to us or our business, we may be subject to enforcement actions, penalties, exclusion and other material limitations on our operations.
Both before and after the approval of our products and agents in development, we, our products, development agents,products, operations, facilities, suppliers, distributors, contract manufacturers, contract research organizations and contract testing laboratories are subject to extensive and, in certain circumstances, expanding regulation by federal, state and local government agencies in the U.S. as well as non-U.S. and transnational laws and regulations, with regulations differing from country to country and even state to state, including, among other things, anti-trust and competition laws and regulations, and data privacy laws and regulations such as the General Data Protection Regulation in the European Union.Union and the CCPA and the CPRA. In the U.S., the FDA regulates, among other things, the pre-clinical testing, clinical trials, manufacturing, safety, efficacy, potency, labeling, storage, record keeping, quality systems, advertising, promotion, sale, distribution, and import and export of drug products. We are required to register our business for permits and/or licenses with, and comply with the stringent requirements of the FDA, the NRC, the HHS, Health Canada, the EMA, the MHRA, the NMPA, state and provincial boards of pharmacy, state and provincial health departments and other federal, state and provincial agencies. Violation of any of these regulatory schemes, individually or collectively, could disrupt our business and have a material adverse effect on our business, results of operations, financial condition and cash flows.

Under U.S. law, for example, we are required to report certain adverse events and production problems, if any, to the FDA.FDA or other federal or state regulators. We also have similar adverse event and production reporting obligations outside of the U.S., including to the EMA and MHRA. Additionally, we must comply with requirements concerning advertising and promotion for our products, including the prohibition on the promotion of our products for indications thatfor which they have not been approved by the FDA or a so-called “off-label use” or promotion that is inconsistent with the approved labeling. If the FDA determines that our promotional materials constitute unlawful promotion, it could request that we modify our promotional materials or subject us to regulatory or enforcement actions. Also, quality control and manufacturing procedures at our own facility and at third partythird-party suppliers must conform to cGMP regulations and other applicable law after approval, and the FDA periodically inspects manufacturing facilities to assess compliance with cGMPs and other applicable law, and, from time to time, makes those cGMPs more stringent. Accordingly, we and others with whom we work must expend time, money, and effort in all areas of regulatory compliance, including manufacturing, production and quality control. If in the future issues arise at our own manufacturing facility or at a third partythird-party manufacturer, the FDA could take regulatory action which could limit or suspend the ability of that third party to manufacture our products or have any additional products approved at the relevant facility for manufacture until the issues are resolved and remediated. Such a limitation or suspension could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We are also subject to laws and regulations that govern financial and other arrangements between pharmaceutical manufacturers and healthcare providers, including federal and state anti-kickback statutes, federal and state false claims laws and regulations, federal and state “sunshine” laws and regulations and other fraud and abuse laws and regulations.
We must offer discounted pricing or rebates on purchases of pharmaceutical products under various federal and state healthcare programs, such as the Medicaid drug rebate program, the “federal ceiling price” drug pricing program, the 340B drug pricing program and the Medicare Part D Program. We must also report specific prices to government agencies under healthcare programs, such as the Medicaid drug rebate program and Medicare Part B. Our Medicaid Drug Rebate agreements require us to report certain price information to the federal government. Determination of

the rebate amount that we pay to state Medicaid programs for our products, of prices charged to government and certain private payors for our products, or of amounts paid for our products under government healthcare programs, depends upon information reported by us to the government. If we provide customers or government officials with inaccurate information about the products’ pricing or eligibility for coverage, or the products fail to satisfy coverage requirements, we could be terminated from the rebate program, be excluded from participation in government healthcare programs, or be subject to potential liability under the False Claims Act or other laws and regulations.
Failure to comply with other requirements and restrictions placed upon us or our third partythird-party manufacturers or suppliers by laws and regulations can result in fines, civil and criminal penalties, exclusion from federal healthcare programs and debarment. Possible consequences of those actions could include:
Substantial modifications to our business practices and operations;
Significantly reduced demand for our products (if products become ineligible for reimbursement under federal and state healthcare programs);
A total or partial shutdown of production in one or more of the facilities where our products are produced while the alleged violation is being remediated;
Delays in or the inability to obtain future pre-market clearances or approvals; and
Withdrawals or suspensions of our current products from the market.

Regulations are subject to change as a result of legislative, administrative or judicial action, which may also increase our costs or reduce sales or otherwise adversely impact our products. For example, on April 16, 2021 in the case Genus Medical Technologies LLC v. Food and Drug Administration, the U.S. Court of Appeals for the D.C. Circuit held that a product (other than a combination product) that meets the definitions of both “drug” and “device” in the FDCA must be regulated as a device. On August 9, 2021, the FDA announced that, as part of its implementation of this court decision, the FDA intended to regulate products that meet both the device and drug definition as devices, except where Congress intended a different classification. The FDA further indicated that it intended to bring previously classified products into line with the court decision and would reexamine whether individual imaging agents meet the device definition. In connection with its announcement, the FDA requested comments from the industry on five topics: categories of products implicated by the court decision; the transition process; the transition timing; user fee transitions; and determining drug or device status. We submitted comments to the FDA in response to its request for comments. While we question whether the FDA has authority to make this change, we believe that pre-existing law already establishes that a broad spectrum of imaging agents have already been established by Congress to be “drugs”, and do not believe that any of our imaging agents meets the definition of a “device” under the FDCA. We can give no assurance that the FDA will agree with our position. In addition, if the FDA determines that one or more of our imaging agents meet the definition of a “device”, we do not know when such reclassification would be effective, how any transition rules would be formulated or applied, and whether or not the legal framework provided by the Hatch-Waxman Act would be preserved for some time after such reclassification. A reclassification of one or more of our imaging agents as a “device” could have a material adverse effect on our business, results of operations, financial condition and cash flows.
Our marketing and sales practices may contain risks that could result in significant liability, require us to change our business practices, and restrict our operations in the future.
We are subject to numerous domestic (federal, state and local) and foreign laws addressing fraud and abuse in the healthcare industry, including the FCA and federal Anti-Kickback Statute, self-referral laws, the FCPA, the Bribery Act, FDA promotional restrictions, the federal disclosure (sunshine) law and state marketing and disclosure (sunshine) laws. Violations of these laws are punishable by criminal or civil sanctions, including substantial fines, imprisonment and exclusion from participation in healthcare programs such as Medicare and Medicaid as well as health programs outside the U.S., and even settlement of alleged violations can result in the imposition of corporate integrity agreements that could subject us to additional compliance and reporting requirements and impact our business practices. These laws and regulations are complex and subject to changing interpretation and application, which could restrict our sales or marketing practices. Even minor and inadvertent irregularities could potentially give rise to a charge that the law has been violated. Although we believe we maintain an appropriate compliance program, we cannot be certain that the program will adequately detect or prevent violations and/or the relevant regulatory authorities may disagree with our interpretation. Additionally, if there is a change in law, regulation or administrative or judicial interpretations, we may have to change one or more of our business practices to be in compliance with these laws. Required changes could be costly and time consuming.
If our operations are found to be in violation of these laws or any other government regulations that apply to us, we may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, imprisonment, the curtailment or restructuring of our operations, or exclusion from state and federal healthcare programs including Medicare and Medicaid, any of which could have a material adverse effect on our business, results of operations, financial condition and cash flows.
Risks Related to Our Business Operations and Financial Results
The COVID-19 pandemic has had, and could continue to have, a material impact on our business, results of operation and financial condition, operating results, cash flows and prospects.
Towards the end of the first quarter of 2020 we began to experience, and through the date of this filing we are continuing to experience, impacts to our business and operations related to the COVID-19 pandemic, including the impact of hospital staffing challenges, vaccination mandates, employee absences due to illness, and a decline in the volume of procedures and treatments using our products. In response to the pandemic, healthcare providers have, and may need to further, reallocate resources, such as physicians, staff and facilities, as they prioritize limited resources and personnel capacity to focus on the treatment of patients with COVID-19 and implement limitations on access to hospitals and other medical institutions due to concerns about the potential spread of COVID-19 in such settings. Vaccination mandates may also create additional personnel and capacity constraints.
For example, we believe that during the fourth quarter of 2021 sales of DEFINITY were impacted by hospital nursing and sonographer shortages, and sales of AZEDRA were impacted by treatment capacity constraints in hospitals, treatment deferrals and cancellations by patients, and access restrictions by hospitals. There has also been a reduction in pulmonary ventilation studies in which our Xenon is used because of institutional concerns and professional society guidelines relating to the possible spread of COVID-19 to technicians and other patients, given that Xenon is both inhaled and exhaled by the patient. As a result, Xenon sales have decreased. We expect Xenon sales to continue to be at reduced levels so long as COVID-19 precautions remain in place. Similarly, with respect to AZEDRA, the resurgence of COVID-19 infection rates impacted sales by creating treatment capacity constraints in hospitals, treatment deferrals and cancellations by patients and access restrictions by hospitals.

These actions have significantly delayed the provision of other medical care including procedures involving our products, having an adverse effect on our revenue. These measures and challenges may continue for the duration of the COVID-19 pandemic, and such duration is uncertain and may significantly reduce our revenue and cash flows while the pandemic continues and thereafter until we and our customers are able to resume normal business operations. We cannot predict the magnitude or duration of the pandemic’s impact on our business.
In connection with the COVID-19 pandemic, the following risks could have a material effect on our business, financial condition, results of operations and prospects:
The delay or cancellation by hospitals and clinics of the procedures in which our products are used as a result of their COVID-19 response efforts and the duration of such effects, thereby reducing sales of our products for an unknown period of time;
The inability or unwillingness of some patients to visit hospitals or clinics in order to undergo procedures in which our products are used, thereby reducing sales of our products for an unknown period of time;
The inability of some patients to pay for procedures and/or the co-pay associated with those procedures in which our products are used due to job loss or lack of insurance, thereby reducing sales of our products for an unknown period of time;
The inability of our distributors, radiopharmacy customers, PET manufacturing partners, hospitals, clinics and other customers to conduct their normal operations, including supplying or conducting procedures in which our products are used, because of their COVID-19 response efforts, or the reduced capacity or productivity of their employees and contractors as a result of possible illness, quarantine or other inability to work, thereby reducing sales of our products for an unknown period of time;
The financial challenges experienced by certain of our customers due to the COVID-19 pandemic resulting in increased pressure from those customers on the pricing of our commercial products;
The inability of global suppliers of raw materials or components used in the manufacture of our products, or contract manufacturers of our products, to supply and/or transport those raw materials, components and products to us in a timely and cost effective manner due to shutdowns, interruptions or delays, limiting and potentially precluding the production of our finished products, impacting our ability to supply customers, reducing our sales, increasing our costs of goods sold, and reducing our absorption of overhead;
The partial or complete delay or cancellation of international or domestic flights by our airfreight carriers, resulting in our inability to receive raw materials, components and products from our global suppliers or to ship and deliver our finished products to our domestic and international customers in a timely or cost effective manner, thereby potentially increasing our freight costs as we seek alternate, potentially more expensive, methods to ship raw materials, components or products, and negatively impacting our sales;
The reduced capacity or productivity of our complex, on-campus operations as a result of possible illness, quarantine or other inability of our employees and contractors to work, despite all of the preventative measures we continue to undertake to protect the health and safety of our workforce;
The illiquidity or insolvency of our suppliers, contract manufacturers (including our PET manufacturing partners) or freight carriers whose business activities could be shut down, interrupted or delayed;
The illiquidity or insolvency of our distributors or customers, or their inability to pay our invoices in full or in a timely manner, due to the reduction in their revenues caused by the cancellation or delay of procedures and other factors, which could potentially reduce our cash flow, reduce our liquidity and increase our bad debt reserves;
A portion of our raw materials or finished product inventory may expire due to reduced demand for our drugs;
Delays in our ability, and the ability of our contract research organizations and development partners to conduct, enroll and complete clinical development programs such as our ARROW Phase 2 study in mCRPC or the flurpiridaz F 18 Phase 3 clinical development program currently being conducted by GE Healthcare;
Delays of regulatory reviews and approvals, including with respect to our product candidates and manufacturing facilities, by the FDA or other health or regulatory authorities;
Decreased sales of those of our products that are promotionally sensitive, like DEFINITY and AZEDRA, due to the reduction of in-person sales and marketing activities and training caused by travel restrictions, quarantines, other similar social distancing measures and more restrictive hospital access policies;
Our ability to maintain employee morale and motivate and retain management personnel and other key employees as a result of our previous work week and salary reductions;

A disruption in the operation of our new on-site manufacturing facility, which would delay implementation of our supply diversification strategy for DEFINITY and impact our ability to benefit from a lower cost of goods for that product;
A reduction in revenue with continued incurrence of high fixed costs relating to our already-existing, complex and expensive radiopharmaceutical manufacturing facility could adversely affect our cash flows, liquidity and ability to comply with the financial covenants in our 2019 Facility;
The increased reliance on our personnel working from home, which may negatively impact employee engagement, loyalty and productivity, or disrupt, delay or otherwise adversely impact our business, including through the increased employee resignations and retirements;
The instability in worldwide economies, financial markets, social institutions, labor markets and the healthcare systems as a result of the COVID-19 pandemic, which could result in an economic downturn that could adversely impact our business, results of operations and financial condition, as well as that of our suppliers, distributors, customers or other business partners; and
A recurrence of the COVID-19 pandemic, or the development and spread of new strains of COVID-19 after social distancing and other similar measures have been relaxed.
The extent to which the COVID-19 pandemic impacts our business and our results of operations and financial condition will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge in connection with the severity of the virus, the ability to treat and ultimately prevent it with vaccines, its potential recurrence or transformation into new or more contagious or virulent strains, and further actions that federal, state, local, or foreign governments may take to contain its impact.
We may not be able to hire or retain the number of qualified personnel, particularly scientific, medical and sales personnel, required for our business, which would harm the development and sales of our products and limit our ability to grow.
Competition in our industry for highly skilled scientific, healthcare and sales personnel is intense. During 2021,In connection with the launch and continued growth of PYLARIFY, we hired additional employees to assist us with the commercialization of PYLARIFY, including in sales, marketing, reimbursement, quality and medical affairs. Although we were successful in hiring and onboarding those employees and we have not had any material difficulty in the past in hiring or retaining qualified personnel, if we are unable to retain our existing personnel, or attract and train additional qualified personnel, either because of competition in our industry for these personnel prolonged remote working conditions due to the COVID-19 pandemic, or insufficient financial resources, then our growth may be limited and it could have a material adverse effect on our business.
If we lose the services of our key personnel, our business could be adversely affected.
Our success is substantially dependent upon the performance, contributions and expertise of our chief executive officer, executive leadership and senior management team. Mary Anne Heino, our Chief Executive Officer, and President, and other members of our executive leadership and senior management team play a significant role in formulating and executing on our long-term strategy, generating business and overseeing operations. We have an employment agreementagreements with Ms. Heino, Brian Markison, who will succeed Ms. Heino as Chief Executive Officer effective March 1, 2024, and a limited number of other individuals on our executive leadership

team, although we cannot prevent them from terminating their employment with us. We do not maintain key person life insurance policies on any of our executive officers. While we have experienced some turnover on our executive leadership team, we have generally been able to fill positions by either promoting existing employees or attracting new, qualified individuals to lead key functional areas. For example, on January 23, 2024, we announced that effective March 1, 2024, Brian Markison, our current Chair of the Board, will become our Chief Executive Officer, and Mary Anne Heino, our current Chief Executive Officer, will retire and become the Chair of the Board. Our inability to retain our existing executive leadership and senior management team, maintain an appropriate internal succession program or attract and retain additional qualified personnel could have a material adverse effect on our business.
Our business depends on our ability to successfully introduce new products and adapt to a changing technology and medical practice landscape.
The healthcare industry is characterized by continuous technological development resulting in changing customer preferences and requirements. The success of new product development depends on many factors, including our ability to fund development of new agentsproducts or new indications for existing agents,products, anticipate and satisfy customer needs, obtain timely regulatory approval based on performance of our agentsproducts in development versus their clinical studytrial comparators, develop and manufacture products in a cost-effective and timely manner, maintain advantageous positions with respect to intellectual property and differentiate our products from our competitors. To compete successfully in the marketplace, we must make substantial investments in new product development, whether internally or externally through licensing or acquisitions. Our failure to introduce new and innovative products in a timely manner would have an adverse effect on our business, results of operations, financial condition and cash flows.

Even if we are able to develop, manufacture and obtain regulatory approvals for our new products, the success of these products would depend upon market acceptance and adequate coding, coverage and payment. Levels of market acceptance for our new products could be affected by a number of factors, including:
The availability of alternative products from our competitors;
The breadth of indications in which alternative products from our competitors can be marketed;
The price of our products relative to those of our competitors;
The timing of our market entry;
Our ability to enter into commercial contracts to sell our products;
Our ability to market and distribute our products effectively;
Market acceptance of our products; and
Our ability to obtain adequate coding, coverage and payment.payment, including the availability of TPT Status.
The field of diagnostic medical imaging is dynamic, with new products, including equipment, software and products, continually being developed and existing products continually being refined. Our own diagnostic imaging agents compete not only with other similarly administered imaging agents but also with imaging agents employed in different and often competing diagnostic modalities, and in the case of DEFINITY, echocardiography procedures without ultrasound enhancing agents. New hardware, software or agentsproducts in a given diagnostic modality may be developed that provide benefits superior to the then-dominant hardware, software and agentsproducts in that modality, resulting in commercial displacement of the agents.products. Similarly, changing perceptions about comparative efficacy and safety including, among other things, comparative radiation exposure, as well as changing availability of supply or the availability of additional payments for new devices such as TPT Status, may favor one agentproduct over another or one modality over another. In addition, new or revised appropriate use criteria developed by professional societies, to assist physicians and other health care providers in making appropriate imaging decisions for specific clinical conditions, can and have reduced the frequency of and demand for certain imaging modalities and imaging agents. To the extent there is technological obsolescence in any of our products that we manufacture, resulting in lower unit sales or decreased unit sales prices, we will have increased unit overhead allocable to the remaining market share, which could have a material adverse effect on our business, results of operations, financial condition and cash flows. Similar risks could apply to therapeutic products, including products we are developing.
Our future growth may depend on our ability to identify and acquire or in-license additional products, businesses or technologies, and if we do not successfully do so, or otherwise fail to integrate any new products, lines of business or technologies into our operations, we may have limited growth opportunities and it could result in significant impairment charges or other adverse financial consequences.
Even after giving effect to the Progenics Acquisition, we are continuing toWe seek to acquire or in-license products, businesses or technologies that we believe are a strategic fit with our business strategy. Future acquisitions or in-licenses, however, may entail numerous operational and financial risks, including:
A reduction of our current financial resources;

Table of Contents

Incurrence of substantial debt or dilutive issuances of securities to pay for acquisitions;
Difficulty or inability to secure financing to fund development activities for those acquired or in-licensed technologies;
Higher than expected acquisition and integration costs;
Disruption of our business, customer base and diversion of our management’s time and attention to develop acquired products or technologies; and
Exposure to unknown liabilities.
We may not have sufficient resources to identify and execute the acquisition or in-licensing of third partythird-party products, businesses and technologies and integrate them into our current infrastructure. In particular, we may compete with larger pharmaceutical companies and other competitors in our efforts to establish new collaborations and in-licensing opportunities. These competitors likely will have access to greater financial resources than we do and may have greater expertise in identifying and evaluating new opportunities. Furthermore, there may be an overlap between our products or customers and the companies which we acquire that may create conflicts in relationships or other commitments detrimental to the integrated businesses. Additionally, the time between our expenditures to acquire or in-license new products, technologies or businesses and the subsequent generation of revenues from those acquired products, technologies or businesses (or the timing of revenue recognition related to licensing agreements and/or strategic collaborations) could cause fluctuations in our financial performance from period to period. Finally, if we devote resources to potential acquisitions or in-licensing opportunities that are never completed, or if we fail to realize the anticipated benefits of those efforts, we could incur significant impairment charges or other adverse financial consequences.

Challenges with product quality or product performance, including defects, caused by us or our manufacturers or suppliers could result in a decrease in customers and revenues, unexpected expenses and loss of market share.
The manufacture of our products is highly exacting and complex and must meet stringent quality requirements, due in part to strict regulatory requirements, including the FDA’s cGMPs. Problems may be identified or arise during manufacturing, quality review, packaging or shipment for a variety of reasons including equipment malfunction, failure to follow specific protocols and procedures, defective raw materials and environmental factors. Additionally, manufacturing flaws, component failures, design defects, off-label uses or inadequate disclosure of product-related information could result in an unsafe condition or the injury or death of a patient. Those events could lead to a recall of, or issuance of a safety alert relating to, our products.products or could harm our reputation and our ability to market our products in the future. We also may undertake voluntarily to recall products or temporarily shut down production lines based on internal safety and quality monitoring and testing data.
Quality, regulatory and recall challenges could cause us to incur significant costs, including costs to replace products, lost revenue, damage to customer relationships, time and expense spent investigating the cause and costs of any possible settlements or judgments related thereto and potentially cause similar losses with respect to other products. These challenges could also divert the attention of our management and employees from operational, commercial or other business efforts. If we deliver products with defects, or if there is a perception that our products or the processes related to our products contain errors or defects, we could incur additional recall and product liability costs, and our credibility and the market acceptance and sales of our products could be materially adversely affected. Due to the strong name recognition of our brands, an adverse event involving one of our products could result in reduced market acceptance and demand for all products within that brand, and could harm our reputation and our ability to market our products in the future. In some circumstances, adverse events arising from or associated with the design, manufacture or marketing of our products could result in the suspension or delay of regulatory reviews of our applications for new product approvals. These challenges could have a material adverse effect on our business, results of operations, financial condition and cash flows.
In the ordinary course of business, we may be subject to product liability claims and lawsuits, including potential class actions, alleging that our products have resulted or could result in an unsafe condition or injury.
Any product liability claim brought against us, with or without merit, could be time consuming and costly to defend and could result in an increase of our insurance premiums. Although we have not had any such claims to date, claims that could be brought against us might not be covered by our insurance policies. Furthermore, although we currently have product liability insurance coverage with policy limits that we believe are customary for pharmaceutical companies in the diagnostic medical imaging industry and adequate to provide us with insurance coverage for foreseeable risks, even where the claim is covered by our insurance, our insurance coverage might be inadequate and we would have to pay the amount of any settlement or judgment that is in excess of our policy limits. We may not be able to obtain insurance on terms acceptable to us or at all, since insurance varies in cost and can be difficult to obtain. Our failure to maintain adequate insurance coverage or successfully defend against product liability claims could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We use hazardous materials in our business and must comply with environmental laws and regulations, which can be expensive.

Table of Contents

Our operations use hazardous materials and produce hazardous wastes, including radioactive, chemical and, in certain circumstances, biological materials and wastes. We are subject to a variety of federal, state and local laws and regulations as well as non-U.S. laws and regulations relating to the transport, use, handling, storage, exposure to and disposal of these materials and wastes. Environmental laws and regulations are complex, change frequently and have generally become more stringent over time. We are required to obtain, maintain and renew various environmental permits and nuclear licenses. Although we believe that our safety procedures for transporting, using, handling, storing and disposing of, and limiting exposure to, these materials and wastes comply in all material respects with the standards prescribed by applicable laws and regulations, the risk of accidental contamination or injury cannot be eliminated. We place a high priority on these safety procedures and seek to limit any inherent risks. We generally contract with third parties for the disposal of wastes generated by our operations. Prior to disposal, weWe store any low level radioactive waste at our facilitiesfacility and dispose of the materials in accordance with applicable laws and regulations. A majority of our low level radioactive waste is held to decay until the materials are no longer considered radioactive. Although we believe we have complied in all material respects with all applicable environmental, health and safety laws and regulations, we cannot assure you that we have been or will be in compliance with all such laws at all times. If we violate these laws, we could be fined, criminally charged or otherwise sanctioned by regulators. We may be required to incur further costs to comply with current or future environmental and safety laws and regulations. In addition, in the event of accidental contamination or injury from these materials, we could be held liable for any damages that result and any such liability could exceed our resources.
We previously leased a small portion of our North Billerica, Massachusetts facilitycampus to PerkinElmer for the manufacturing, finishing and packaging of certain radioisotopes, including Strontium-90, which has physical characteristics that make it more challenging to work with and dispose of than our own commercial radioisotopes, including a much longer half-life. PerkinElmer decommissioned its space and vacated the premises as of December 30, 2021. We are fully indemnified by PerkinElmer under our lease for any property damage or personal injury resulting from their activities in our facility. If any release or excursion of radioactive materials took place from their leased space that resulted in property damage or personal injury, the indemnification obligations were

not honored, and we were forced to cover any related remediation, clean-up or other expenses, depending on the magnitude, the cost of such remediation, clean-up or other expenses could have a material adverse effect on our business, results of operations, financial condition and cash flows.
While we have budgeted for current and future capital and operating expenditures to maintain compliance with these laws and regulations, we cannot assure you that our costs of complying with current or future environmental, health and safety laws and regulations will not exceed our estimates or adversely affect our results of operations and financial condition. Further, we cannot assure you that we will not be subject to additional environmental claims for personal injury, investigation or cleanup in the future based on our past, present or future business activities.
If we are unable to protect our intellectual property, our competitors could develop and market products with features similar to our products, and demand for our products may decline.
Our commercial success will depend in part on obtaining and maintaining patent and trade secret protection of our commercial products and technologies and agentsproducts in development as well as successfully enforcing and defending these patents and trade secrets against third parties and their challenges, both in the U.S. and in foreign countries. We will only be able to protect our intellectual property from unauthorized use by third parties to the extent that we maintain the secrecy of our trade secrets and can enforce our valid patents and trademarks.
The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. In addition, changes in either the patent laws or in interpretations of patent laws in the U.S. or other countries may diminish the value of our intellectual property and we may not receive the same degree of protection in every jurisdiction. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third partythird-party patents.
The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:
We might not have been the first to make the inventions covered by each of our pending patent applications and issued patents, and we could lose our patent rights as a result;
We might not have been the first to file patent applications for these inventions or our patent applications may not have been timely filed, and we could lose our patent rights as a result;
Others may independently develop similar or alternative technologies or duplicate any of our technologies;
It is possible that none of our pending patent applications will result in any further issued patents;
Our issued patents may not provide a basis for commercially viable drugs, may not provide us with any protection from unauthorized use of our intellectual property by third parties, and may not provide us with any competitive advantages;

Table of Contents

The validity or enforceability of our patent applications or patents may be subject to challenge through interferences, oppositions, post-grant review, ex-parte re-examinations, inter partes review or similar administrative proceedings;
While we generally apply for patents in those countries where we intend to make, have made, use or sell patented products, we may not be able to accurately predict all of the countries where patent protection will ultimately be desirable and may be precluded from doing so at a later date;
We may choose not to seek patent protection in certain countries where the actual cost outweighs the perceived benefit at a certain time;
Patents issued in foreign jurisdictions may have different scopes of coverage than our U.S. patents and so our products may not receive the same degree of protection in foreign countries as they would in the U.S.;
We may not develop additional proprietary technologies that are patentable; or
The patents of others may have an adverse effect on our business.business; or
The cost to defend our patents may be significant and may result in litigation which could be costly and time consuming.
Moreover, the issuance of a patent is not conclusive as to its validity or enforceability. A third party may challenge the validity or enforceability of a patent even after its issuance by the USPTO or the applicable foreign patent office. It is also uncertain how much protection, if any, will be afforded by our patents if we attempt to enforce them and they are challenged in court or in other proceedings, which may be brought in U.S. or non-U.S. jurisdictions to challenge the validity of a patent.

The initiation, defense and prosecution of intellectual property suits (including Hatch-Waxman related litigation), interferences, oppositions and related legal and administrative proceedings are costly, time consuming to pursue and result in a diversion of resources, including a significant amount of management time. The outcome of these proceedings is uncertain and could significantly harm our business. If we are not able to enforce and defend the patents of our technologies and products, then we will not be able to exclude competitors from marketing products that directly compete with our products, which could have a material and adverse effect on our business, results of operations, financial condition and cash flows.
For DEFINITY, we continue to actively pursue patents in both the U.S. and internationally. In the U.S. for DEFINITY we have four Orange Book-listed method of use patents, one of which expires in 2035 and three of which expire in 2037, as well as additional manufacturing patents that are not Orange Book-listed expiring in 2023 and 2037. In the U.S. for DEFINITY RT, we have five Orange Book-listed patents, including a composition of matter patent which expires in 2035. Outside of the U.S., we are currently pursuing additional DEFINITY and DEFINITY RT patents to obtain similar patent protection as in the U.S. The Orange Book-listed patents include a patent on the use of VIALMIX RFID, which expires in 2037; additional VIALMIX RFID patent applications have been submitted in major markets throughout the world.
We also rely on trade secrets and other know-how and proprietary information to protect our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We use reasonable efforts to protect our trade secrets, but our employees, consultants, contractors, outside scientific partners and other advisors may unintentionally or willfully disclose our confidential information to competitors or other third parties. Enforcing a claim that a third party improperly obtained and is using our trade secrets is expensive, time consuming and resource intensive, and the outcome is unpredictable. In addition, courts outside the U.S. are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how. We rely on confidentiality agreements with our collaborators, employees, consultants and other third parties and invention assignment agreements with our employees to protect our trade secrets and other know-how and proprietary information concerning our business. These confidentiality agreements may not prevent unauthorized disclosure of trade secrets and other know-how and proprietary information, and there can be no guarantee that an employee or an outside party will not make an unauthorized disclosure of our trade secrets, other technical know-how or proprietary information, or that we can detect such an unauthorized disclosure. We may not have adequate remedies for any unauthorized disclosure. This might happen intentionally or inadvertently. It is possible that a competitor will make use of that information, and that our competitive position will be compromised, in spite of any legal action we might take against persons making those unauthorized disclosures, which could have a material and adverse effect on our business, results of operations, financial condition and cash flows.
We rely on our trademarks, trade names and brand names to distinguish our products from the products of our competitors, and have registered or applied to register many of these trademarks, including, among others, AZEDRA®, AZEDRA Service Connection®, Cardiolite®, DEFINITY®, DEFINITY RTTM, EXINI®, Find, Fight and Follow®, Find > Fight > FollowTM, Lantheus®, Lantheus Medical Imaging®, LUMINITY®, Molecular Insight®, NEUROLITE®, Progenics®, Progenics Pharmaceuticals®, PYLARIFY®, TechneLite®, VIALMIX®, and VIALMIX RFID®.trademarks. We cannot assure you that any pending trademark applications will be approved. Third parties may also oppose our trademark applications, or otherwise challenge our use of the trademarks. If our trademarks are successfully challenged, we could be forced to re-brand our products, which could result in loss of brand recognition, and could require us to devote resources to advertising and marketing new brands. Further, we cannot assure you that competitors will not infringe our trademarks, or that we will have adequate resources to enforce our trademarks.
Our patents are subject to generic challenge, and the validity, enforceability and commercial value of these patents are highly uncertain.
Our ability to obtain and defend our patents impacts the commercial value of our products and product candidates. Third parties have challenged and are likely to continue challenging the patents that have been issued or licensed to us. Patent protection involves complex legal and factual questions and, therefore, enforceability is uncertain. Our patents may be challenged, invalidated, held to be unenforceable, or circumvented, which could negatively impact their commercial value. Furthermore, patent applications filed outside the United States may be challenged by other parties, for example, by filing third partythird-party observations that argue against patentability or an opposition. Such opposition proceedings are increasingly common in the EU and are costly to defend. For example, we received notices of opposition to three European patents relating to RELISTOR.
Pursuant to the RELISTOR license agreement between us and Bausch, Bausch has the first right to enforce the intellectual property rights at issue and is responsible for the costs of such enforcement. At the same time, we may incur substantial further costs in supporting the effort to uphold the validity of patents or to prevent infringement. Patent disputes are frequent, costly and can preclude, delay or increase the cost of commercialization of products. Progenics has previously been and is currently involved in patent litigation, and we expect to be subject to patent litigation in the future.

We may be subject to claims that we have infringed, misappropriated or otherwise violated the patent or other intellectual property rights of a third party. The outcome of any of these claims is uncertain and any unfavorable result could adversely affect our business, financial condition and results of operations.
We may be subject to claims by third parties that we have infringed, misappropriated or otherwise violated their intellectual property rights. We are aware of intellectual property rights held by third parties that relate to products or technologies we are developing. For example, we are aware of other groups investigating PSMA or related compounds and monoclonal antibodies directed at PSMA, PSMA-targeted imaging agents and therapeutics, and methylnaltrexone and other peripheral opioid antagonists, and of patents held, and patent applications filed, by these groups in those areas. While the validity of these issued patents, the patentability of pending patent applications and the applicability of any of them to our products and programs are uncertain, if asserted against us, any related patent or other intellectual property rights could adversely affect our ability to commercialize our products.
We may be subject to litigation over infringement claims regarding the products we manufacture or distribute or intend to manufacture or distribute. For example, on January 26, 2024, we were sued in the United States District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the filing of our ANDA for PNT2003 and Paragraph IV certification, consistent with the process established by the Hatch-Waxman Act. This type of litigation can be costly and time consuming and could divert management’s attention and resources, generate significant expenses, damage payments (potentially including treble damages) or restrictions or prohibitions on our use of our technology, which could adversely affect our business, results of operations, financial condition and cash flows. In addition, if we are found to be infringing on proprietary rights of others, we may be required to develop non-infringing technology, obtain a license (which may not be available on reasonable terms, or at all), make substantial one-time or ongoing royalty payments, or cease making, using and/or selling the infringing products, any of which could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We may be adversely affected by prevailing economic conditions and financial, business and other factors beyond our control.
Our ability to attract and retain customers, invest in and grow our business, maintain our desired levels of costs of goods sold and operating expenses and meet our financial obligations depends on our operating and financial performance, which, in turn, is subject to numerous factors, including the prevailing economic conditions and financial, business and other factors beyond our control, such as the rate of unemployment, the number of uninsured persons in the U.S. and inflationary pressures.pressures, including escalating energy prices. We cannot anticipate all the ways in which the current or future economic climate and financial market conditions could adversely impact our business. We are exposed to risks associated with reduced profitability and the potential financial instability of our customers, many of which may be adversely affected by volatile conditions in the financial markets. For example, unemployment and underemployment, and the resultant loss of insurance, may decrease the demand for healthcare services and pharmaceuticals. If fewer patients are seeking medical care because they do not have insurance coverage, our customers may experience reductions in revenues, profitability and/or cash flow that could lead them to modify, delay or cancel orders for our products. If customers are not successful in generating sufficient revenue or are precluded from securing financing, they may not be able to pay, or may delay payment of, accounts receivable that are owed to us. This, in turn, could adversely affect our financial condition and liquidity. To the extent prevailing economic conditions result in fewer procedures being performed, our business, results of operations, financial condition and cash flows could be adversely affected.
Similarly, we would expect our costs of goods sold and other operating expenses to change in the future in line with periodic inflationary changes in price levels. Because we intend to retain and continue to use our property and equipment, we believe that the incremental inflation related to the replacement costs of those items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation, contract services, and transportation costs, which could increase our level of expenses and the rate at which we use our resources. While we generally believe that we will be able to offset the effect of price-level changes by adjusting our product prices and implementing operating efficiencies, any material unfavorable changes in price levels could have a material adverse effect on our financial condition, results of operations and cash flows.
Our business is subject to international economic, political and other risks that could negatively affect our results of operations or financial position.
For the year ended December 31, 2021,2023, we derived approximately 10%2.6% of our revenues and expendedsourced approximately 25%11.2% of our costs of goods sold outside of the fifty United States. Accordingly, our business is subject to risks associated with doing business internationally, including:
Less stable political and economic environment and changes in a specific country’s or region’s political or economic conditions;

Changes in trade policies, regulatory requirements and other barriers, including, for example, U.S. trade sanctions against Iran and those countries and entities doing business with Iran, which could adversely impact international isotope production and, indirectly, our global supply chain;
Potential global disruptions in air transport, due to COVID-19, which could adversely affect our international supply chains for radioisotopes and DEFINITY RT as well as international distribution channels for our commercial products;
Entering into, renewing or enforcing commercial agreements with international governments or provincial authorities or entities directly or indirectly owned or controlled by such governments or authorities, such as our Belgian, Australian and South African isotope suppliers, IRE, ANSTO and NTP, and our Chinese development and commercialization partner, Double-Crane;

Unfavorable labor regulations;
Greater difficulties in relying on non-U.S. courts to enforce either local or U.S. laws, particularly with respect to intellectual property;
Greater potential for intellectual property piracy;
Greater difficulties in managing and staffing non-U.S. operations, including our EXINI operations in Sweden;
The need to ensure compliance with the numerous in-country and international regulatory and legal requirements applicable to our business in each of these jurisdictions and to maintain an effective compliance program to ensure compliance with these requirements, including in connection with the GDPR in the EU;
Changes in public attitudes about the perceived safety of nuclear facilities;
Civil unrest or other catastrophic events; and
Longer payment cycles of non-U.S. customers and difficulty collecting receivables in non-U.S. jurisdictions.
These factors are beyond our control. The realization of any of these or other risks associated with operating outside the United States could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We face currency and other risks associated with international sales.
We generate revenue from export sales, as well as from operations conducted outside the United States. Operations outside the U.S. expose us to risks including fluctuations in currency values, trade restrictions, tariff and trade regulations, U.S. export controls, U.S. and non‑U.S. tax laws, shipping delays and economic and political instability. For example, violations of U.S. export controls, including those administered by the U.S. Treasury Department’s Office of Foreign Assets Control, could result in fines, other civil or criminal penalties and the suspension or loss of export privileges which could have a material adverse effect on our business, results of operations, financial conditions and cash flows.
Many of our customer relationships outside of the U.S. are, either directly or indirectly, with governmental entities, and we could be adversely affected by violations of the FCPA and similar worldwide anti-bribery laws outside the U.S.
The FCPA, the Bribery Act and similar worldwide anti-bribery laws in non-U.S. jurisdictions generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business.
The FCPA prohibits us from providing anything of value to foreign officials for the purposes of obtaining or retaining business or securing any improper business advantage. It also requires us to keep books and records that accurately and fairly reflect our transactions. Because of the predominance of government-sponsored healthcare systems around the world, many of our customer relationships outside of the U.S. are, either directly or indirectly, with governmental entities and are therefore subject to the FCPA and similar anti-bribery laws in non-U.S. jurisdictions. In addition, the provisions of the Bribery Act extend beyond bribery of foreign public officials and are more onerous than the FCPA in a number of other respects, including jurisdiction, non-exemption of facilitation payments and penalties.

Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that have experienced governmental corruption to some degree, and in certain circumstances strict compliance with anti-bribery laws may conflict with local customs and practices. Despite our training and compliance programs, our internal control policies and procedures may not always protect us from reckless or criminal acts committed by our employees or agents. Violations of these laws, or allegations of those violations, could disrupt our business and result in a material adverse effect on our results of operations, financial condition and cash flows.

Our business depends on the continued effectiveness and availability of our information technology infrastructure, and failures of this infrastructure could harm our operations.
To remain competitive in our industry, we must employ information technologies to support manufacturing processes, quality processes, distribution, R&D and regulatory applications and that capture, manage and analyze large streams of data in compliance with applicable regulatory requirements. We rely extensively on technology, some of which is managed by third partythird-party service providers, to allow the concurrent conduct of work sharing around the world. As with all information technology, our equipment and infrastructure age and become subject to increasing maintenance and repair and our systems generally are vulnerable to potential damage or interruptions from fires, natural disasters, power outages, blackouts, machinery breakdown, telecommunications failures and other unexpected events, as well as to break-ins, sabotage, increasingly sophisticated intentional acts of vandalism or cybersecurity threats which, due to the nature of such attacks, may remain undetected for a period of time. As these threats continue to evolve, we may be required to expend additional resources to enhance our information security measures or to investigate and remediate any information security vulnerabilities. Given the extensive reliance of our business on technology, any substantial disruption or resulting loss of data that is not avoided or corrected by our backup measures could harm our business, reputation, operations and financial condition.
A disruption in our computer networks, including those related to cybersecurity, could adversely affect our operations or financial position.
We believe that our cybersecurity program is designed to effectively mitigate the risks of material cybersecurity incidents. However, our management does not expect that our cybersecurity program will prevent or detect all occurrences of cybersecurity incidents, material or otherwise, and there is potential risk that certain cybersecurity breaches may go undetected for a period of time. The design of our cybersecurity program is based, in part, upon certain assumptions about the likelihood of future incidents, and there can be no assurance that any design will prevent or detect all cybersecurity breaches. Over time, certain aspects of cybersecurity programs may become inadequate because of changes in technology, sophistication of cybersecurity attacks, emerging threats or other conditions, or the degree of compliance with our policies and procedures may deteriorate.
We rely on our computer networks and systems, some of which are managed by third parties, to manage and store electronic information (including sensitive data such as confidential business information, personally identifiable data and personal health information), and to manage or support a variety of critical business processes and activities. We may face threats to our networks from unauthorized access, security breaches and other system disruptions. Despite our security measures, our infrastructure may be vulnerable to external or internal attacks. Any such security breach may compromise information stored on our networks and may result in significant data losses or theft of sensitive or proprietary information. A cybersecurity breach could hurt our reputation by adversely affecting the perception of customers and potential customers ofabout the security of their orders and personal information, as well as the perception of our manufacturing partners of the security of their proprietary information. In addition, a cybersecurity attack could result in other negative consequences, including disruption of our internal operations, increased cybersecurity protection costs, lost revenue, regulatory actions or litigation. Any disruption of internal operations could also have a material adverse impact on our results of operations, financial condition and cash flows. To date, we have not experienced any known material cybersecurity attacks.
We may be limited in our ability to utilize, or may not be able to utilize, net operating loss carryforwards to reduce our future tax liability.
As of December 31, 2021,2023, we had U.S. federal income tax loss carryforwards of $476.2$297.6 million, $338.1$157.9 million of which will expire between 20222027 and 2037, $138.0$139.6 million of which can be carried forward indefinitely, and state income tax loss carryforwards of $17.4$12.5 million, tax-effected. We may be limited in our ability to use these tax loss carryforwards to reduce our future U.S. federal and state income tax liabilities if our future income is not sufficient to absorb the losses, or if we were to experience another “ownership change” as specified in Section 382 of the Internal Revenue Code including if we were to issue a certain amount of equity securities, certain of our stockholders were to sell shares of our common stock, or we were to enter into certain strategic transactions.
We are involved in various legal proceedings that are uncertain, costly and time-consuming and could have a material adverse impact on our business, financial condition and results of operations.
From time to time we are involved in legal proceedings and disputes and may be involved in litigation in the future. For example, on January 26, 2024, we were sued in the United States District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the
45

Table of Contents

filing of our ANDA for PNT2003 and Paragraph IV certification, consistent with the process established by the Hatch-Waxman Act. These proceedings are complex and extended and occupy the resources of our management and employees. These
Legal proceedings are also costly to prosecute and defend and may involve substantial awards or damages payable by us if not found in our favor. We may also be required to pay substantial amounts or grant certain rights on unfavorable terms in order to settle such proceedings.
Defending against or settling such claimslegal proceedings and any unfavorable legal decisions, settlements or orders could have a material adverse effect on our business, financial condition and results of operations and could cause the market value of our common stock to decline.
In particular, the pharmaceutical and medical device industries historically have generated substantial litigation concerning the manufacture, use and sale of products, and we expect this litigation activity to continue. As a result, we expect that patents related to our products will routinely be challenged, and our patents may not be upheld. In order to protect or enforce patent rights, we may initiate litigation against third parties. If we are not successful in defending an attack on our patents and maintaining exclusive rights to market one or more of our products still under patent protection, we could lose a significant portion of sales in a very short period. We may also become subject to infringement claims by third parties and may have to defend against charges that we violated patents or the proprietary rights of third parties. If we infringe the intellectual property rights of others, we could lose our right to develop, manufacture or sell products, or could be required to pay monetary damages or royalties to license proprietary rights from third parties.
In addition, in the U.S., it has become increasingly common for patent infringement actions to prompt claims that antitrust laws have been violated during the prosecution of the patent or during litigation involving the defense of that patent. Such claims by direct
50

Table of Contents

and indirect purchasers and other payors are typically filed as class actions. The relief sought may include treble damages and restitution claims. Similarly, antitrust claims may be brought by government entities or private parties following settlement of patent litigation, alleging that such settlements are anti-competitive and in violation of antitrust laws. In the U.S. and Europe, regulatory authorities have continued to challenge as anti-competitive so-called “reverse payment” settlements between branded and generic drug manufacturers. We may also be subject to other antitrust litigation involving competition claims unrelated to patent infringement and prosecution. A successful antitrust claim by a private party or government entity against us could have a material adverse effect on our business, financial condition and results of operations and could cause the market value of our common stock to decline.
Risks Related to our Portfolioand our Strategic Partners’ Portfolios of Clinical Development Candidates
We may not, or may take longer to, realize the expected benefits and opportunities related to, the POINT License Agreements.
On December 20, 2022, we announced the closing of a set of strategic collaborations with an affiliate of POINT, in which we were granted a license to exclusive worldwide rights (excluding Japan, South Korea, China (including Hong Kong, Macau and Taiwan), Singapore and Indonesia) to co-develop and commercialize POINT’s PNT2002 and PNT2003 product candidates (the “POINT License Agreements”). The expected benefits and opportunities related to the POINT License Agreements may not be realized or may take longer to realize than expected due to, for example, challenges and uncertainties inherent in product research, development, manufacturing, regulatory approval, marketing and competition. In particular, activities under the POINT License Agreements may not result in viable products suitable for commercialization in a timely manner or at all, due to a variety of reasons, including any inability of the relevant parties to perform their commitments and obligations under the POINT License Agreements. The POINT License Agreements impose various development, regulatory filing, commercialization and other obligations on us, and require us to meet development timelines or to exercise commercially reasonable efforts to develop and commercialize licensed products. We, along with our counterparty in the POINT License Agreements, may not be able to meet expected or planned regulatory milestones and timelines due to a number of factors, including, with respect to PNT2003, potential litigation under the Hatch-Waxman Act that could impose a stay on FDA approval of up to 30 months. Even if the licensed products are suitable for commercialization in a timely manner, we may not achieve the expected revenues from the sale of such products, and our revenue, ability to achieve profitability and return on investment may be adversely affected.
With respect to PNT2002, on December 18, 2023, we announced positive topline results from SPLASH, the Phase 3 registrational trial for PNT2002. Although the topline results indicated that the SPLASH trial met its primary endpoint, at the time of our topline analysis, interim OS results were immature. We expect additional, follow-up data in 2024 prior to the potential submission of an NDA; however, we can give no assurance that, as additional data become available, such data will not be materially different from the topline data we previously published, or that such data will support an NDA filing, FDA approval, or successful commercialization of PNT2002.
In addition, we are dependent on POINT to develop commercial product capacity and manufacture clinical and commercial supply for both PNT2002 and PNT2003, as well as supply for our EAP for PNT2002.

Disagreements with the counterparty in the POINT License Agreements over proprietary rights, contract interpretation or the preferred course of product research, development or marketing, might cause delays in performance of the POINT License Agreements or termination of the POINT License Agreements, or might result in litigation or arbitration, which could be time-consuming and expensive.
In spite of our efforts, if we fail to comply with our obligations under the POINT License Agreements, the counterparty in the POINT License Agreements may conclude that we have materially breached and may terminate one or both of the POINT License Agreements, in which event we may lose our rights to develop and market PNT2002 and PNT2003 or incur liability for damages.
Any of the foregoing risks could materially and adversely affect our business, results of operations and prospects and the trading price of our common stock.
We may not, or may take longer to, realize the expected benefits and opportunities related to, the Cerveau Acquisition.
On February 6, 2023, we announced that we acquired Cerveau. Cerveau holds the rights under a license agreement to develop and commercialize MK-6240, an investigational second-generation F 18-labeled PET imaging agent that targets Tau tangles in Alzheimer’s disease. MK-6240 is currently being used in more than 90 active clinical trials for several Alzheimer’s disease therapeutic candidates being developed. While we believe that MK-6240, as a Tau imaging agent, has the potential to play an important role in patient staging, selection, and monitoring for future treatments and could be a surrogate endpoint for treatment efficacy, we can give no assurance that we will be successful with continued development, regulatory approval and commercialization of the product candidate or that disagreements with the counterparty to our license agreement for MK-6240 or the Selling Stockholders will not arise over proprietary rights, contract interpretation or the preferred course of product research, development or marketing that might cause delays or termination of the license agreement, or might result in litigation or arbitration, which could be time-consuming and expensive.
The process of developing new drugs and obtaining regulatory approval is complex, time-consuming and costly, and the outcome is not certain.
We currently have two clinical development programs in the U.S. – 1095, including those related to PNT2002, PNT2003, MK-6240 and LMI 1195,LNTH-1363S, and are exploring additional lifecycle management opportunities for some of our current products, including AZEDRA.PYLARIFY. We also have a number of strategic partnerships relating to obtaining additional indications for existing commercial products or regulatory approval for clinical development candidates. To obtain regulatory approval for these agentsproducts in the indications being pursued, we must conduct extensive human tests, which are referred to as clinical trials, as well as meet other rigorous regulatory requirements, as further described in Part I, Item 1. “Business—Regulatory Matters.” Satisfaction of all regulatory requirements typically takes many years and requires the expenditure of substantial resources. A number of other factors may cause significant delays in the completion of our clinical trials, including unexpected delays in the initiation of clinical sites, slower than projected enrollment, competition with ongoing clinical trials and scheduling conflicts with participating clinicians, regulatory requirements, limits on manufacturing capacity and failure of an agentinvestigational product to meet required standards for administration to humans. In addition, it may take longer than we project to achieve study endpoints and complete data analysis for a clinical trial or we may decide to slow down the enrollment in a trial in order to conserve financial resources.resources or for other reasons.
Our products in development are also subject to the risks of failure inherent in drug development, drug testing and testing.regulatory approval. The results of preliminary studies do not necessarily predict clinical success, and larger and later stage clinical trials may not produce the same results as earlier stage trials. Sometimes, products that have shown promising results in early clinical trials have subsequently suffered significant setbacks in later clinical trials. AgentsProducts in later stage clinical trials may fail to show desired safety and efficacy traits, despite having progressed through initial clinical testing. In addition, the data collected from clinical trials of our products in development may not be sufficient to support regulatory approval, or regulators could interpret the data differently and less favorably than we do. Further, the design of a clinical trial can determine whether its results will support approval of a product, and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. Clinical trials of potential products often reveal that it is not practical or feasible to continue development efforts. Regulatory authorities may require us or our partners to conduct additional clinical testing, in which case we would have to expend additional time and resources. Depending on the regulatory pathway selected for drug approval, such as by filing an ANDA or Section 505(b)(2) NDA that requires sending notice to the innovator of a drug, regulatory approval may also be delayed by litigation brought under the Hatch-Waxman Act. For example, on January 26, 2024, we were sued in the United States District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the filing of our ANDA for PNT2003 and Paragraph IV certification, consistent with the process established by the Hatch-Waxman Act. The approval process may also be delayed by changes in government regulation, future legislation or administrative action or changes in regulatory policy that occur prior to or during regulatory review. The failure to provide clinical and preclinical data that are adequate to demonstrate to the satisfaction of the regulatory authorities that our products in development are safe and effective for their proposed use will delay or preclude approval and will prevent us from marketing those products.

Table of Contents

We are not permitted to market our products in development in the U.S. or other countries until we have received requisite regulatory approvals. For example, securing FDA approval for a new drug requires the submission of an NDA to the FDA for our products in development. The NDA must include extensive nonclinical and clinical data and supporting information to establish the product’s safety and effectiveness for each indication. The NDA must also include significant information regarding the chemistry, manufacturing and controls for the product. The FDA review process can take many years to complete, and approval is never guaranteed. If a product is approved, the FDA may limit the indications for which the product may be marketed, require extensive warnings on the product labeling, impose restricted distribution programs, require expedited reporting of certain adverse events, or require costly ongoing requirements for post-marketing clinical studiestrials and surveillance or other risk management measures to monitor the safety or efficacy of the product. In some instances, products in development may also be approved by filing an ANDA or Section 505(b)(2) NDA with the FDA (as further described in Part I, Item 1. “Business—Regulatory Matters—Hatch-Waxman Act.”); provided, however, that seeking regulatory approval under such pathways may subject the product candidate to delays caused by litigation brought by an innovator of similar drugs under the Hatch-Waxman Act, as is the case with our ANDA application and Paragraph IV certification for PNT2003. Markets outside of the U.S. also have requirements for approval of products with which we must comply prior to marketing. Obtaining regulatory approval for marketing of a product in one country does not ensure we will be able to obtain regulatory approval in other countries, but a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in other countries. Also, any regulatory approval of any of our products in development, once obtained, may be withdrawn. Approvals might not be granted on a timely basis, if at all.
We can give no assurance that GE Healthcare will be successful with the further clinical development of flurpiridaz F 18.flurpiridaz.
In May 2015, we announced complete results from the first of two planned Phase 3 clinical trials for flurpiridaz F 18.flurpiridaz. Although the development candidate appeared to be well-tolerated from a safety perspective and outperformed SPECT in a highly statistically significant manner in the co-primary endpoint of sensitivity and in the secondary endpoints of image quality and diagnostic certainty, flurpiridaz F 18 did not meet its other co-primary endpoint of non-inferiority for identifying subjects without disease. In April 2017,
51

Table of Contents

we entered into the License Agreement with GE Healthcare for the continued Phase 3 development and worldwide commercialization of flurpiridaz F 18.flurpiridaz. Under the License Agreement, GE Healthcare will,agreed, among other things, to complete the worldwide development of flurpiridaz F 18 by conducting a second Phase 3 trial and pursue worldwide regulatory approvals. WeIn September 2022, we announced with GE Healthcare that the second Phase 3 clinical trial had met its co-primary endpoints of exceeding a 60% threshold for both sensitivity and specificity for detecting CAD. The findings, shared at an American Society of Nuclear Cardiology conference, also demonstrated that cardiac PET imaging with flurpiridaz had higher diagnostic efficacy and image quality in patients with suspected CAD, compared with SPECT MPI, the predominant procedure currently used in nuclear cardiology. Notwithstanding these findings, we cannot assure any particular outcome from GE Healthcare’s continued Phase 3 development of the agent or from regulatory review of either our or their Phase 3 study of the agent, that any of the data generated in either our or theirGE Healthcare’s sponsored Phase 3 study will be sufficient to support an NDA approval that GE Healthcare will only have to conduct the one additional Phase 3 clinical study prior to filing an NDA, or that flurpiridaz F 18 will ever be approved as a PET MPI imaging agent by the FDA. AnyWhile GE Healthcare recently announced that it had filed an NDA with the FDA for flurpiridaz, any failure or significant delay in completing clinical trials for our product candidates or in receiving regulatory approval for the sale of our product candidatesflurpiridaz may harm our business and delay or prevent us from being able to generate additional future royalty revenue from product sales.
Even if clinical development candidates receive regulatory approval, we can give no assurance that they can be successfully commercialized.
Even if our clinical development candidates proceed through their clinical trials and ultimately receive regulatory approval, there is no guarantee that an approved product can be manufactured in commercial quantities at a reasonable cost or that such a product will be successfully marketed or distributed. For example, the manufacturing, marketing and distribution of a radiopharmaceutical like flurpiridaz F 18and MK-6240 will require the creation of a field-based network of specialized PET manufacturing facilities, or PMFs, with radioisotope-producing cyclotrons, similar to what we created for PYLARIFY, and will need to be manufactured and distributed rapidly to end-users.
In addition, obtaining adequate coding, coverage and payment at appropriate payment levels for any clinical development candidate will be critical, including not only coverage from Medicare, Medicaid, and other government payors, but also from private payors. We can give no assurance, even if a clinical development candidate were to obtain regulatory approval, that adequate coding, coverage and payment could be secured to allow the approved products to become successfully commercialized.
We have been and expect to continue to be dependent on partners for the development of certain product candidates, which expose us to the risk of reliance on these partners.
In connection with our ongoing development activities, we currently depend, and expect to continue to depend, on numerous collaborators. For example, in addition to our collaboration with Curium on PYLCLARI in Europe, GE Healthcare on flurpiridaz F 18,and POINT on PNT2002 and PNT2003, we have other collaborations with Bayer to develop and commercialize products using our PSMA antibody technology, with Curium for the development and commercialization of PYLARIFY in Europe, and with ROTOP for the development and commercialization of 1404 in Europe.products. In addition, certain clinical trials for our product candidates may be conducted by government-sponsored agencies, and consequently will be dependent on governmental participation and funding. These arrangements expose us to the same considerations we face when contracting with third parties for our own trials.
48

Table of Contents

If any of our collaborators breach or terminate its agreement with us or otherwise fail to conduct successfully and in a timely manner the collaborative activities for which they are responsible, the preclinical or clinical development or commercialization of the affected product candidate or research program could be delayed or terminated. We generally do not control the amount and timing of resources that our collaborators devote to our programs or product candidates. We also do not know whether current or future collaboration partners, if any, might pursue alternative technologies or develop alternative products either on their own or in collaboration with others, including our competitors, as a means for developing treatments for the diseases or conditions targeted by our collaborative arrangements. Our collaborators are also subject to similar development, regulatory, manufacturing, cyber-security and competitive risks as us, which may further impede their ability to successfully perform the collaborative activities for which they are responsible. Setbacks of these types to our collaborators could have a material adverse effect on our business, results of operations and financial condition.
We depend on licenses from third parties for our rights to develop and commercialize certain product candidates. If we fail to achieve milestone requirements or to satisfy other conditions, we may lose those rights under those license agreements, and our business, results of operations and financial condition could be adversely affected.
Many of our products or product candidates incorporate rights licensed by third parties -- for example, we license patent rights on PYLARIFY, from JHUPNT2002, PNT2003, MK-6240, LNTH-1363S and on RELISTOR from Wyeth LLC.NM-01. We could lose the rights to develop or commercialize these products and product candidates if the related license agreement is terminated due to a breach by us or otherwise. In addition, we are required to make substantial cash payments, achieve milestones and satisfy other conditions, including filing for and obtaining marketing approvals and introducing products, sometimes in accordance with established timelines, to maintain rights under our license agreements. Due to the nature of these agreements and the uncertainties of development, we may not be able to achieve milestones or satisfy conditions to which we have contractually committed, and as a result may be unable to maintain our rights under these licenses. If we do not comply with our license agreements, the licensors may terminate them, which could result in our losing our rights to, and therefore being unable to commercialize, related products. This loss could have a material adverse effect on our business, results of operations and financial condition.
Risks Related to Our Capital Structure
The conditional conversion feature of the 2.625% Convertible Senior Notes due 2027, if triggered, may adversely affect our financial condition and operating results.
On December 8, 2022, we issued $575.0 million in aggregate principal amount of 2.625% Convertible Senior Notes due 2027 (the “Notes”), which included $75.0 million in aggregate principal amount of Notes sold pursuant to the full exercise of the initial purchasers’ option to purchase additional Notes. The Notes were issued under an indenture, dated as of December 8, 2022 (the “Indenture”), among Holdings, LMI, and U.S. Bank Trust Company, National Association (“U.S. Bank”), as Trustee. Prior to the close of business on the business day immediately preceding September 15, 2027, the Notes may be converted at the option of the holders upon occurrence of specified events and during certain periods, and thereafter until the close of business on the business day immediately preceding the maturity date, the Notes may be converted at any time. If one or more holders elect to convert their Notes, we would be required to settle any converted principal amount of such Notes through the payment of cash and by paying or delivering, at our election, cash, shares of our common stock, or a combination of cash and shares, with respect to the remainder of our conversion obligation in excess of the aggregate principal amount of the Notes being converted, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.
The issuance or sale of shares of our common stock, or rights to acquire shares of our common stock, could depress the trading price of our common stock.
We may conduct future offerings of our common stock, preferred stock or other securities that are convertible into or exercisable for our common stock to finance our operations or fund acquisitions, or for other purposes. In addition, we expect to continue to grant equity awards to directors, officers and employees under our equity incentive plans. If we issue additional shares of our common stock or rights to acquire shares of our common stock, if any of our existing stockholders sells a substantial amount of our common stock, or if the market perceives that such issuances or sales may occur, then the trading price of our common stock may significantly decrease. In addition, our issuance of additional shares of common stock will dilute the ownership interests of our existing common stockholders.
Repurchases by us of our common stock may affect the value of our common stock.
In December 2022, our Board authorized the repurchase of up to $150.0 million in aggregate amount of our common stock under certain circumstances. We used approximately $75.0 million of the net proceeds from the Notes to repurchase shares of our common stock from purchasers of Notes in privately negotiated transactions effected with or through one of the initial purchasers or its affiliate. The purchase price per share of the common stock repurchased in such transactions was equal to the closing sale price per share of our

Risks Relatedcommon stock on December 5, 2022, which was $56.01 per share. Following this initial repurchase, we may from time to Our Capital Structuretime repurchase additional shares of our common stock. Such repurchases could increase, or prevent a decrease in, the market price of our common stock.
We have indebtedness which may limit our financial and operating activities and may adversely affect our ability to incur additional debt to fund future needs.
As of December 31, 2021,2023, we had approximately $175.0$575.0 million of total principal indebtedness remaining under our five‑year secured term loan facility, which matures on June 30, 2024 (the “2019 Term Facility” and the loans thereunder, the “2019 Term Loans”)Notes and availability of $200.0$350.0 million under our five-year revolving credit facility (the “20192022 Revolving Facility” and, together with the 2019 Term Facility, the “2019 Facility”).Facility. Our indebtedness and any future indebtedness we incur could:
Require us to dedicate a substantial portion of cash flow from operations to the payment of interest on and principal of our indebtedness, thereby reducing the funds available for other purposes, including for working capital, capital expenditures and acquisitions;
Make it more difficult for us to satisfy and comply with our obligations with respect to our outstanding indebtedness, namely the payment of interest and principal;
Make it more difficult to refinance the outstanding indebtedness;
Subject us to increased sensitivity to interest rate increases;
Make us more vulnerable to economic downturns, adverse industry or company conditions or catastrophic external events;
Limit our ability to withstand competitive pressures;
Reduce our flexibility in planning for or responding to changing business, industry and economic conditions; and
Place us at a competitive disadvantage to competitors that have relatively less debt than we have.
In addition, our substantial level of indebtedness could limit our ability to obtain additional financing on acceptable terms, or at all, for working capital, capital expenditures and general corporate purposes. Our liquidity needs could vary significantly and may be affected by general economic conditions, industry trends, performance and many other factors outside our control.
We may not be able to generate sufficient cash flow to meet our debt service obligations.
Our ability to generate sufficient cash flow from operations to make scheduled payments on our debt obligations will depend on our future financial performance, which will be affected by a range of economic, competitive and business factors, many of which are outside of our control. If we do not generate sufficient cash flow from operations to satisfy our debt obligations, including interest and principal payments, our credit ratings could be downgraded, and we may have to undertake alternative financing plans, such as refinancing or restructuring our debt, selling assets, entering into additional corporate collaborations or licensing arrangements for one or more of our products in development, reducing or delaying capital investments or seeking to raise additional capital. We cannot assure you that any refinancing would be possible, that any assets could be sold, licensed or partnered, or, if sold, licensed or partnered, of the timing of the transactions and the amount of proceeds realized from those transactions, that additional financing could be obtained on acceptable terms, if at all, or that additional financing would be permitted under the terms of our various debt instruments then in effect. Furthermore, our ability to refinance would depend upon the condition of the financial and credit markets. Our inability to generate sufficient cash flow to satisfy our debt obligations, or to refinance our obligations on commercially reasonable terms or on a timely basis, would have an adverse effect on our business, results of operations and financial condition.
Despite our indebtedness, we may incur more debt, which could exacerbate the risks described above.
We and our subsidiaries may be able to incur substantial additional indebtedness in the future subject to the limitations contained in the agreements governing our debt, including the 20192022 Revolving Facility. Although these agreements restrict us and our restricted subsidiaries from incurring additional indebtedness, these restrictions are subject to important exceptions and qualifications. For example, we are generally permitted to incur certain indebtedness, including indebtedness arising in the ordinary course of business, indebtedness among restricted subsidiaries and us and indebtedness relating to hedging obligations. If we or our subsidiaries incur additional debt, the risks that we and they now face as a result of our leverage could intensify. In addition, the 20192022 Revolving Facility will not prevent us from incurring obligations that do not constitute indebtedness under the agreements.that agreement.
Our 20192022 Revolving Facility contains restrictions that will limit our flexibility in operating our business.
Our 20192022 Revolving Facility contains various covenants that limit our ability to engage in specified types of transactions. These covenants limit our and our restricted subsidiaries’ ability to, among other things:
Maintain net leverage above certain specified levels;
Maintain interest coverage below certain specified levels;
5350

Maintain interest coverage below certain specified levels;
Incur additional debt;
Pay dividends or make other distributions;
Redeem stock;
Issue stock of subsidiaries;
Make certain investments;
Create liens;
Enter into transactions with affiliates; and
Merge, consolidate or transfer all or substantially all of our assets.
A breach of any of these covenants could result in a default under the 20192022 Revolving Facility. We may also be unable to take advantage of business opportunities that arise because of the limitations imposed on us by the restrictive covenants under our indebtedness.
As LIBOR is phased out, as anticipated, we will need to agree to a replacement index rate to be used under our 2019 Facility, which may have an adverse effect on our financial condition.
The use of LIBOR, as it relates to the Company’s 2019 Term Facility, is expected to be phased out by the end of June 2023. The 2019 Facility does not specify a particular “hard-wired” replacement index rate (or related margin) when LIBOR becomes unavailable, but relies on the administrative agent and the Company reaching agreement on such a replacement rate (and related margin) that gives due consideration to the then prevailing market convention for determining rates of interest for syndicated loans denominated in U.S. dollars in the United States. We expect to amend our credit facilities to provide a market-based replacement index rate and margin prior to the time when LIBOR is no longer available. Any replacement rate will be based on a negotiation between us and the administrative agent and could result in an increase in our interest expense.
U.S. credit markets may impact our ability to obtain financing or increase the cost of future financing, including interest rate fluctuations based on macroeconomic conditions that are beyond our control.
During periods of volatility and disruption in the U.S., European, or global credit markets, obtaining additional or replacement financing may be more difficult and the cost of issuing new debt or replacing or repaying our 20192022 Facility could be higher than under our current 20192022 Facility. Higher cost of new debt may limit our ability to have cash on hand for working capital, capital expenditures and acquisitions on terms that are acceptable to us. Additionally, our 20192022 Facility has variable interest rates. By its nature, a variable interest rate will move up or down based on changes in the economy and other factors, all of which are beyond our control. If interest rates increase, our interest expense could increase, affecting earnings and reducing cash flows available for working capital, capital expenditures and acquisitions.
The CVRs we issued as part of the Progenics Acquisition may result in substantial future payments to the holders of the CVRs; in addition, the actual payments made in connection with the CVRs, if any, may not be consistent with the estimated fair value of the CVRs that we are required to prepare for accounting purposes.
As part of the consideration for the Progenics Acquisition, we issued CVRs to the stockholders of Progenics and holders of in-the-money Progenics equity awards entitling them to future cash payments of 40% of PYLARIFY net sales over $100.0 million in 2022 and over $150.0 million in 2023, subject to an aggregate cap. These payments could be substantial. In addition, we are obligated to exercise a level of effort, expertise and resources consistent with those normally used in a medical diagnostics business similar to our size and resources with respect to commercializing a product of similar market potential at a similar stage in its product life to PYLARIFY. We are also required to produce net sales statements for PYLARIFY that may be reviewed and challenged by CVR holders, with any disagreement to be resolved by an independent accountant.
Because the CVRs are considered contingent consideration liabilities, for accounting purposes we are required by accounting principles generally accepted in the U.S. to estimate their fair value on a recurring basis. Adjustments in the estimated fair value of the CVRs can impact our consolidated financial statements on a quarterly or annual basis. The estimated fair value of the CVRs is determined based on a Monte Carlo simulation model that includes significant estimates and assumptions pertaining to commercialization events, sales targets, market conditions and discount rates. These estimates and assumptions are subject to the judgment of our management team and are not prepared with a view towards public disclosure of projected sales. Our sales targets are also subject to significant economic, competitive, industry and other uncertainties and contingencies, which are difficult to predict and in many cases are beyond our control. We can give no assurance that the actual amounts paid, if any, in connection with the CVRs will be consistent with any recurring fair value estimate for such CVRs.

Our stock price could fluctuate significantly, which could cause the value of your investment to decline, and you may not be able to resell your shares at or above your purchase price.
Securities markets worldwide have experienced, and may continue to experience, significant price and volume fluctuations. This market volatility, as well as general economic, market or political conditions, could reduce the market price of our common stock regardless of our operating performance. The high and low closing sales prices of our common stock during the twelve months ended December 31, 2023 were $99.65 and $47.76, respectively. The trading price of our common stock is likely to be volatile and subject to wide price fluctuations in response to various factors, including:
Market conditions in the broader stock market;
Actual or anticipated fluctuations in our quarterly financial and operating results;
Issuance of new or changed securities analysts’ reports or recommendations;
Investor perceptions of us and the pharmaceutical and medical device industries;
Sales, or anticipated sales, of large blocks of our stock;
Acquisitions or introductions of new products or services by us or our competitors, including our ongoing commercial launch of PYLARIFY;competitors;
Positive or negative results from our clinical development programs;
Additions or departures of key personnel;
Regulatory or political developments;
Loss of intellectual property protections;
Litigation and governmental investigations;
Geopolitical events; and
Changing economic conditions.

Table of Contents

These and other factors may cause the market price and demand for our common stock to fluctuate substantially, which may limit or prevent investors from readily selling their shares of common stock and may otherwise negatively affect the liquidity of our common stock. In addition, in the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the company that issued the stock. If any of our stockholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit. Such a lawsuit could also divert the time and attention of our management from our business, which could significantly harm our profitability and reputation.
If securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations regarding our stock, or if our results of operations do not meet their expectations, our stock price and trading volume could decline.
The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover us downgrades our stock, or if our results of operations do not meet their expectations, our stock price could also decline.
We do not anticipate paying any cash dividends for the foreseeable future.future, and accordingly, stockholders must rely on stock appreciation for any return on their investment.
We have never declared or paid cash dividends on our capital stock. We currently intend to retain our future earnings, if any, for the foreseeable future, to repay indebtedness and to fund the development and growth of our business. We do not intend to pay any dividends to holders of our common stock and the agreements governing our senior secured credit facilities limit our ability to pay dividends. As a result, capital appreciation in the price of our common stock, if any, will be your only source of gain on an investment in our common stock.
Anti-takeover provisions in our charter documents and Delaware law and certain provisions in the Notes and Indenture may make an acquisition of us more difficult.
Our amended and restated certificate of incorporation and bylaws, as amended and restated, contain provisions that delay, defer or discourage transactions involving an actual or potential change in control of us or change in our management. These provisions may also discourage bids for our common stock at a premium over market price or adversely affect the market price of, and the voting and other rights of the holders of, our common stock. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors other than the candidates nominated by our Board. In addition, we are incorporated in Delaware and subject to the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit large stockholders from consummating a merger with, or acquisition of, us. These provisions may deter an acquisition of us that might otherwise be attractive to stockholders.
Certain provisions in the Notes and the Indenture could make it more difficult or more expensive for a third party to acquire us. For example, if a takeover would constitute a fundamental change, holders of the Notes will have the right to require us to repurchase their Notes in cash. In addition, if a takeover constitutes a make-whole fundamental change, we may be required to increase the conversion rate for holders who convert their Notes in connection with such takeover. In either case, and in other cases, our obligations under the Notes and the Indenture could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management, including in a transaction that holders of our common stock may view as favorable.

Item 1C. Cybersecurity
Risk management and strategy
With respect to cybersecurity risks, we have invested and continually invest in new cybersecurity services, technologies, and capabilities. On an ongoing basis we provide our employees with comprehensive cybersecurity awareness training around phishing, malware and other cybersecurity risks, all in a manner reasonably intended to educate employees to safely avoid cyber attacks and mitigate the risk of employee related security breaches. In support of our cybersecurity program, our systems and services undergo regular reviews by management to determine if any insufficiencies in cybersecurity exist.
If an incident is detected, the Cybersecurity team follows the incident response policy to investigate, review and determine the potential impacts of such an incident. If the Cybersecurity team determines that an incident could reasonably be expected to have an impact on the financial condition or operations of the Company, it escalates the incident to the crisis management team, which includes executive management. The crisis management team further evaluates the potential impact and materiality of an event and the

appropriate response required. The crisis management team coordinates the appropriate response effort and communicates, as applicable, to the Audit Committee. To the extent that Cybersecurity incident is determined to be material, the appropriate public disclosures are made.
We monitor material risks from cybersecurity threats relating to potential compromises of sensitive information at our third-party business partners where relevant and reevaluate these risks periodically. We also perform third-party cybersecurity audits at least annually and conduct third-party security reviews and testing of our network, processes and systems periodically.
Impact of cybersecurity risks on business strategy, results of operations or financial condition
We rely on our computer networks and systems, some of which are managed by third-parties, to manage and store electronic information (including sensitive data such as confidential business information, personally identifiable data and personal health information), and to manage or support a variety of critical business processes and activities. We may face threats to our networks from unauthorized access, security breaches and other system disruptions. Despite our security measures, our infrastructure may be vulnerable to external or internal attacks. Any such security breach may compromise information stored on our networks and may result in significant data losses or theft of sensitive or proprietary information. A cybersecurity breach could hurt our reputation by adversely affecting the perception of customers and potential customers about the security of their orders and personal information, as well as the perception of our manufacturing partners of the security of their proprietary information. In addition, a cybersecurity attack could result in other negative consequences, including disruption of our internal operations, increased cybersecurity protection costs, lost revenue, regulatory actions or litigation. Any disruption of internal operations could also have a material adverse impact on our results of operations, financial condition and cash flows.
As of the date of this report, we have not experienced any known cybersecurity incidents, or a series of related incidents, that have materially affected or are reasonably likely to affect us, including our business strategy, results of operations or financial condition. For an additional description of these cybersecurity risks and potential related impacts on us, see “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K.
Governance
Our Board actively oversees our corporate strategy and enterprise risk management (“ERM”) programs, including those relating to cybersecurity and data privacy risks.
Our Audit Committee and Nominating and Corporate Governance Committee are primarily responsible for, among other things, overseeing our compliance and ERM programs, information technology systems, and our processes and data, including cybersecurity and data privacy. These responsibilities include reviewing and discussing with management our policies and processes relating to risk assessment and risk management. Cybersecurity and data privacy are regular topics on the Audit Committee’s agenda and management reviews at least quarterly the results of cybersecurity monitoring and discusses performance metrics, any incidents identified and potential recommended modifications to our technology, organization training, awareness and governance with our Audit Committee. A summary of these results are also reported by the Audit Committee to the Board at least annually.
Management, including our Chief Information Officer (“CIO”), who has over 25 years of experience serving primarily in the life science industry and is a recognized industry leader, is responsible for monitoring and assessing cybersecurity risks. Management reviews and determines the effectiveness of both internal and third-party leveraged expertise to ensure we have the appropriate knowledge base for risk coverage.

Recent Developments
CEO Succession Plan
On January 23, 2024, we announced that, effective March 1, 2024, Brian Markison, our current Chair of the Board, will become our Chief Executive Officer, and Mary Anne Heino, our current Chief Executive Officer, will retire and become the Chair of the Board. As part of this leadership transition, Mr. Markison assumed the role of Executive Chair of the Board as of January 23, 2024 until the effectiveness of his Chief Executive Officer appointment in March, and Board Member Julie McHugh became Lead Independent Director.
Strategic Agreements with Perspective Therapeutics
On January 9, 2024, we announced that we entered into multiple strategic agreements with Perspective, a radiopharmaceutical company that is pursuing advanced treatment applications for cancers throughout the body. Under the agreements, we obtained an option to exclusively license Perspective’s Pb212-VMT- ⍺-NET, a clinical stage alpha therapy in development for the treatment of neuroendocrine tumors, and an option to co-develop certain early-stage therapeutic candidates targeting prostate cancer using Perspective’s innovative platform technology, for an aggregate upfront payment of $28 million in cash. We also agreed to purchase up to 19.9% of Perspective’s outstanding shares of common stock for up to approximately $33 million, subject to Perspective’s completion of a qualified third-party financing transaction and certain other closing conditions. In addition, Perspective agreed to acquire the assets and associated lease of our radiopharmaceutical manufacturing facility in Somerset, New Jersey, subject to customary closing conditions, including regulatory approval.
On January 22, 2024, following the satisfaction of applicable closing conditions, our subsidiary, Lantheus Alpha, purchased 56,342,355 shares of Perspective’s common stock at a purchase price of $0.37 per share in a private placement transaction. The total consideration for the purchase was approximately $20.8 million in cash, which resulted in Lantheus Alpha holding approximately

10.74% of Perspective’s common stock as of the purchase date and retaining the right to purchase additional shares to bring its ownership up to an aggregate of 19.9%.
Exclusive License for PNT2002 and PNT2003
On December 20, 2022, we announced the closing of a set of strategic collaborations with POINT Biopharma Global Inc. (“POINT”), in which we were granted a license to exclusive worldwide rights (excluding Japan, South Korea, China (including Hong Kong, Macau, and Taiwan), Singapore, and Indonesia) to co-develop and commercialize POINT’s PNT2002 and PNT2003 product candidates.
On December 27, 2023, Eli Lilly announced the completion of its acquisition of POINT. The acquisition is no expected to impact the status of the PNT2002 License Agreement, the PNT2003 License Agreement, or the work being performed in connection with those agreements and our collaboration with POINT.
PNT2002
With respect to PNT2002, POINT is generally responsible for funding and development activities required for FDA approval, including generating all clinical and nonclinical data, analysis and other information, and we are responsible for preparing for and seeking regulatory approval for PNT2002, as well as performing and funding all future development and commercialization following such approval. POINT will be responsible for all manufacturing of PNT2002, subject to certain exceptions described in the license and collaboration agreement between Lantheus Two and POINT, dated November 11, 2022 (the “PNT2002 License Agreement”).
In April 2023, we announced with POINT that the FDA had granted Fast Track designation for PNT2002. Fast Track is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and address unmet needs.
On December 18, 2023, we announced positive topline results from SPLASH, the Phase 3 registrational trial for PNT2002. SPLASH was designed to evaluate the efficacy and safety of PNT2002 in patients with mCRPC who have progressed following treatment with an androgen receptor pathway inhibitor (“ARPI”). The SPLASH trial met its primary endpoint, demonstrating a median radiographic progression-free survival (rPFS) per blinded independent central review of 9.5 months for patients treated with PNT2002, compared to 6.0 months for patients treated with ARPI in the control arm, a statistically significant 29% reduction in the risk of radiographic progression or death (hazard ratio (“HR”) 0.71; p=0.0088). At the time of the analysis, interim overall survival (OS) results were immature (46% of protocol-specified target OS events reached), and the HR was 1.11. We expect more mature overall survival data in 2024 prior to the potential submission of a New Drug Application (“NDA”).
PNT2002 demonstrated a favorable safety profile with grade ≥3 treatment-emergent adverse events (TEAEs) per Common Terminology Criteria for Adverse Events, serious TEAEs, and TEAEs leading to discontinuation occurring at lower rates in the PNT2002 arm than in the control arm (30.1%, 17.1%, and 1.9% versus 36.9%, 23.1%, and 6.2%, respectively).
The open-label study randomized 412 patients with PSMA-expressing mCRPC who had progressed on ARPI therapy and either refused or were not eligible for chemotherapy, in a 2:1 randomization ratio. At the time of the analysis, 84.6% of patients who experienced progressive disease in the control arm subsequently crossed over to receive PNT2002. SPLASH was conducted across the U.S., Canada, Europe, and the United Kingdom. Eighty percent of SPLASH patients resided in North America and approximately ten percent of all participants were Black or African American.
During 2023, we worked on establishing an EAP, for PNT2002. EAPs, which are also referred to as compassionate use programs, provide a potential pathway for patients with serious or life-threatening conditions to gain access to an investigational drug for treatment outside of a clinical trial. We expect to enroll the first patient in the EAP for PNT2002 during the first quarter of 2021,2024.
PNT2003
With respect to PNT2003, POINT is responsible for curating all data, analysis and other information necessary for regulatory approval, and supporting us in the preparation of regulatory filings. We are responsible for preparing for and seeking regulatory approval of all such applications, as well as performing and funding all future development and commercialization following such approval. POINT will be responsible for all manufacturing of PNT2003, subject to certain exceptions described in the license and collaboration agreement between Lantheus Three and POINT, dated November 11, 2022 (the “PNT2003 License Agreement”). On January 11, 2024, we completedannounced that our ANDA for PNT2003 had been accepted for filing by the evaluationFDA. Based on the most recent update to the FDA’s online paragraph IV database listings, we believe we are the first applicant to have filed a substantially complete ANDA for Lutetium Lu 177 Dotatate containing a Paragraph IV certification under the provisions of the Hatch-Waxman Act. As the first applicant, we believe we will be eligible for 180 days of generic marketing exclusivity in the U.S. On January 26, 2024, we were sued in the District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the Company’s ANDA filing and Paragraph IV

certification, consistent with the process established by the Hatch-Waxman Act. Under the terms of the Hatch-Waxman Act, FDA approval of our operatingANDA filing could be subject to a stay of up to 30-months. If our filing is stayed for the full 30-month period and reporting structure, includingwe are successful in obtaining FDA approval, we would expect to launch PNT2003 in 2026, although no assurance of that approval or timing can be assured.
For more information, see Note 21, “Acquisition of Assets” in our consolidated financial statements included herein.
Acquisition of Cerveau Technologies, Inc.
On February 6, 2023, we announced that we acquired Cerveau. Cerveau holds the impact on our businessrights under a license agreement to develop and commercialize MK-6240, an investigational second-generation F 18-labeled PET imaging agent that targets Tau tangles in Alzheimer’s disease. Under the terms of the acquisitionagreement, we paid the Selling Stockholders an upfront payment of Progenics,$35.0 million in February 2023 and an additional $10.0 million in May 2023 upon the successful completion of a technology transfer. The Selling Stockholders are also eligible to receive additional development and commercial milestone payments. Additionally, we will pay double-digit royalty payments for research revenue and commercial sales. Research revenue is derived from existing partnerships with pharmaceutical companies that use MK-6240 in clinical trials and includes milestone and dose-related payments. Pursuant to the terms of the stock purchase agreement for Cerveau, certain members of the Selling Stockholders will also provide transition and clinical development services for a prescribed time following the closing of the transaction.
In September 2023, MK-6240 was granted Fast Track designation by the FDA.
For more information, see Note 21, “Acquisition of Assets” in our consolidated financial statements included herein.
Sale of RELISTOR Licensed Intangible Asset Associated with Net Sales Royalties
On August 2, 2023, we sold the right to our RELISTOR net sales royalties, which is classified as a licensed intangible asset (“RELISTOR royalty asset”), under our license agreement with Bausch; we retained the rights to future sales-based milestone payments. We received an initial payment of approximately $98.0 million in connection with the sale and we have the right to receive an additional payment from the buyer of $5.0 million if worldwide net sales of RELISTOR in 2025 exceed a specified threshold. The additional payment would be recognized upon achievement of the specified threshold. Decreases of $63.6 million of license assets and $17.5 million of associated accumulated amortization, as well as a gain of $51.8 million were recorded as a result of the sale. During the fourth quarter of 2023, the Company earned a $15 million sales-based milestone payment.
For more information, see Note 10, “Intangibles, Net and Goodwill” in our consolidated financial statements included herein.
Discontinuation of AZEDRA
On August 15, 2023, we announced our decision to discontinue the production and promotion of AZEDRA and that we would be winding down our Somerset, New Jersey manufacturing site. We will continue manufacturing AZEDRA into the first quarter of 2024, to the extent feasible, with the goal of providing doses of AZEDRA to current patients so they can complete their treatment regimen.
For more information, see Note 10, “Intangibles, Net and Goodwill” in our consolidated financial statements included herein.
Refinancing of 2019 Facility
In December 2022, we refinanced our existing credit facility, consisting of (i) a $200.0 million five-year term loan facility (the “2019 Term Facility”) and (ii) a $200.0 million five-year revolving credit facility (the “2019 Revolving Facility” and, together with the 2019 Term Facility, the “2019 Facility”), with a new $100.0 million delayed draw term loan facility (the “2022 Term Facility” and, the saleloans thereunder, the “Term Loans”) and a new $350.0 million five-year revolving credit facility (the “2022 Revolving Facility” and, together with the 2022 Term Facility, the “2022 Facility”).
We used approximately $7.8 million of our Puerto Rico subsidiary,cash on hand to primarily repay the principal amount of the loans outstanding related to the 2019 Facility through the nine months ended September 30, 2022. In addition, we used approximately $167.6 million of cash on hand to repay in full the aggregate remaining principal amount of the loans outstanding under the 2019 Facility and to pay related interest, transaction fees and expenses.
While the 2022 Term Facility allowed for a delayed draw term loan, the loan was not drawn upon. We recorded a loss on extinguishment of debt of $0.6 million related to the write-off of unamortized debt issuance costs and debt discounts associated with the 2019 Term Facility. In addition, we incurred and capitalized $2.7 million of new deferred financing costs related to the refinancing.

Our business and financial performance have been, and continue to be, affected by the following:
Continued Growth of PYLARIFY Approval and Commercial Launch
On May 27, 2021, we announced that the U.S. Food and Drug Administration (“FDA”) had approved PYLARIFY, an F 18-labeled PET imaging agent targeting prostate-specific membrane antigen (“PSMA”). PYLARIFY is a productPSMA, was approved by the FDA in our radiopharmaceutical oncology product category. WeMay 2021 and commercially launched PYLARIFY in the U.S. in June 2021.
PYLARIFY is a radioactive diagnostic agent indicated for PET imaging of PSMA-positive lesions in men with prostate cancer with suspected metastasis who are candidates for initial definitive therapy and in men with suspected recurrence based on elevated serum prostate-specific antigen (“PSA”)PSA levels. PYLARIFY works by binding to PSMA, a proteinBoth the National Comprehensive Cancer Center guidelines and the Society for Nuclear Medicine and Molecular Imaging appropriate use criteria note that is overexpressed on the surface of more than 90% of primary and metastatic prostate cancer cells. PYLARIFY works with PET/CT technology to produce a combined PET/CT scan that enables the reader of the PET/CT scan to detect and locate the disease.
According to the American Cancer Society, prostate cancer is the second most common cancer in American men -- one in eight American men will be diagnosed with prostate cancer in their lifetimes and over 3.1 million American men are living with prostate cancer today. Based on estimates from third party sources regarding the incidence of prostate cancer in men in the U.S., we believe the market potential for PSMA PET imaging agents, couldincluding PYLARIFY, can be up to 220,000 annual scans, comprisedused for patient selection for PSMA-targeted radioligand therapy. PYLARIFY is available through a diverse, multi-partner network of 90,000 scans for patients with intermediate, unfavorable or high/very high risk of suspected metastases of prostate cancerPET manufacturing facilities (“PMFs”), including both commercial and 130,000 scans for patients with

suspected recurrence of prostate cancer. Because we are in the process of launching this imaging agent, we can give no assurance as to how clinical practice may evolve or what our ultimate market penetration may be.academic partners.
The approval of PYLARIFY was based on data from two Company-sponsored pivotal studies (“OSPREY” and “CONDOR”) designed to establish the safety and diagnostic performance of PYLARIFY across the prostate cancer disease continuum. Results from OSPREY (Cohort A) demonstrated improvement in specificity and positive predictive value of PYLARIFY PET imaging over conventional imaging in men at risk for metastatic prostate cancer prior to initial definitive therapy. CONDOR studied men with biochemical recurrent prostate cancer. In patients with biochemical recurrent prostate cancer and non-informative baseline imaging, PYLARIFY demonstrated high correct localization and detection rates, including in patients with early recurrent disease with low, but rising, PSA blood levels (median PSA 0.8 ng/mL).
Upon commercial launch in June 2021, PYLARIFY was immediately available in select parts of the U.S. Over the course of the remainder of 2021, PYLARIFY availability expanded into additional regions and is now broadly available nationwide. We continue to expand our geographic coverage, customer contracting and market access coverage to serve our customers and the U.S. prostate cancer community.
The commercial launchsuccessful growth of PYLARIFY is complexdependent on our ability to sustain PYLARIFY as the leading PSMA PET imaging agent in an increasingly competitive marketplace. PYLARIFY’s competition includes two commercially available gallium-68-based PSMA imaging agents, an approved fluorine-18-based PSMA imaging agent, and expensive. During 2021, weother non-PSMA-based imaging agents commonly referred to as conventional imaging. We previously hired additional employees to assist us with the commercialization of PYLARIFY, including in sales, marketing, reimbursement, qualitySales, Marketing, Reimbursement, Quality and medical affairs. To manufacture PYLARIFY, we assembled and qualified a nationwide network of PMFs with radioisotope-producing cyclotrons that make F 18, which has a 110-minute half-life, so PYLARIFY is manufactured and distributed rapidly to end-users. After being made on a cyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to a radiopharmacist who prepares and dispenses patient-specific doses of the final product. Because each of the PMFs manufacturing these products is deemed by the FDA to be a separate manufacturing site, each has to be separately approved by the FDA. Although PYLARIFY is now broadly available nationwideMedical Affairs, and we continue to qualify additional PMFs, we can give no assurance that the FDA will continue to approve PMFs in accordance with our planned roll-out schedule. If FDA approval of manufacturing sites is delayed or withdrawn, our future business, results of operations, financial conditionmake commercial investments necessary to drive PYLARIFY awareness and cash flows could be adversely affected.
In addition toadoption. We believe that PYLARIFY currently has the network of PMFs, we have also been working with academic medical centerslargest dedicated field-based commercial team in the U.S. that have radioisotope-producing cyclotronsPSMA PET imaging agent space. Continued growth and which have expressed an interest in manufacturing PYLARIFY. Under this initiative, we would enter into a fee-for-service arrangement under which the academic medical center’s PMF would manufacture and supply batches ofrevenue contribution from PYLARIFY and its radiopharmacy would prepare patient-ready unit doses, in each case for andwill also depend on behalf of us. We would then sell those unit doses to the academic medical center’s hospitals and clinics, and in some instances, to additional customers in the academic medical center’s geographic area, in each case, under separate purchase agreements. The academic medical center’s PMF’sour ability to manufacture and supply batches of PYLARIFY will be subject to FDA approval, and we can give no assurance that the FDA will approve such PMFs in accordance with our planned roll-out schedule.
Our commercial launch also required obtaining adequate coding, coverage and payment for PYLARIFY, including not only coverage from Medicare, Medicaid and other government payors, as well as private payors, but also appropriate payment levels, to adequately cover our customers’ costs of usingdifferentiate PYLARIFY in PET/CT imaging procedures. We received notification that ourlight of the potential loss of TPT Status, including through flexible and dependable access to PYLARIFY nationally, a best in class customer experience and through long-term strategic contracts.
Our HCPCS code, which enables streamlined billing, went into effect as of January 1, 2022. In addition, effective January 1, 2022, the CMS granted Transitional Pass-Through PaymentTPT Status in the hospital outpatient setting (“TPT Status”) for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in that setting.TPT Status for PYLARIFY is expected tocould expire on December 31, 2024. After TPT Status expires, under current Medicare rules, PYLARIFY, similar

We intend to submit comments in connection with CMS’s 2024 rulemaking for 2025 payment calendar year to request that CMS establish separate payment for diagnostics instead of the facility fee a hospital otherwise receives for a PET/CT imaging procedure, and the facility fee does not always cover the cost of a drug used in the procedure.We can give no assurance that any CMS reimbursement in the hospital outpatient setting that follows thecurrent packaged payment following expiration of TPT Status will be adequateStatus.
Our plan to coversuccessfully grow PYLARIFY has also included highlighting its commercial and clinical value, as well as through strategic partnerships and collaborations, both for the costcommercialization of PYLARIFY used in a PET/CT imaging procedure.
We actively pursue patentsour product outside of the United States as well as for the use of our product potentially for additional indications or in connection with the development of PSMA-targeted therapeutics. With respect to commercializing PYLARIFY both in the U.S. and internationally. In the U.S. for PYLARIFY, we have four Orange Book-listed patents, including composition of matter patents, which expire in 2030 and 2037. Outsideoutside of the U.S., we are currently pursuing additional PYLARIFY patentspreviously licensed exclusive rights to obtain similar patent protection asCurium to develop and commercialize piflufolastat F 18 in Europe. In July 2023, Curium announced that it received marketing authorization for piflufolastat F 18 from the European Commission, which will be commercialized in the U.S.EU under the brand name PYLCLARI. With respect to the use of PYLARIFY in connection with the development of PSMA-targeted therapeutics, we have entered into multiple strategic collaborations with pharmaceutical companies. Additional information on collaborations using PYLARIFY are described further under Part I, Item 1. “Business - Strategic Partnerships and Other Revenue – Oncology.”
In connection with the acquisition of Progenics in June 2020, we issued CVRs tied to the financial performance of PYLARIFY. We paid $99.6 million to the CVR holders during May 2023 in full satisfaction of our obligations under the CVRs.
PYLARIFY AI Clearance and Use
During 2021, we also announced that our subsidiary, EXINI was granted 510(k) clearance by the FDA in the U.S. and received CE marking in Europe for aPROMISE. We commercially launched aPROMISE under the name PYLARIFY AI in the U.S. in November 2021. During the second quarter of 2022, we received a new 510(k) clearance for an updated version of our PYLARIFY AI platform.

PYLARIFY AI is artificial intelligence medical device software developeddesigned to assist with the reading and quantification of PYLARIFY scans. The technology automatically analyzes a PSMA PET/CT image to segment anatomical regions – 51 bones and 12 soft tissue organs. This image segmentation enables automated localization, detection and quantification of potential PSMA-avid lesions in a PSMA PET/CT image, which data is then incorporated into a standardized report forthe reporting system used by physicians.
Anticipated During the third quarter of 2023, in collaboration with Curium, we customized and released our PYLARIFY AI platform for use in Europe. At the European Association of Nuclear Medicine meeting in Vienna, the PYLARIFY AI presentation was awarded the Top Rated Oral Presentation for response evaluation of metastatic prostate cancer patients.
Also in the third quarter of 2023, we announced a data agreement with the Prostate Cancer Clinical Trial Consortium (PCCTC) on its IRONMAN Registry for development and validation of PSMA biomarkers with PYLARIFY AI. The IRONMAN is the International Registry for Men with Advanced Prostate Cancer, the Registry is accumulating contextualized clinical and imaging data from more than 100 institutions across the globe.
During 2023, we also entered into an agreement with PIONEER (Prostate Cancer DIagnOsis and TreatmeNt Enhancement through the Power of Big Data in EuRope), led by the European Association of Urology (project Coordinator) and Bayer AG (private leader) to use our AI technology to help validate the clinical utility of PYLARIFY AI enabled PSMA biomarker to diagnose, treat and monitor prostate cancer patients. PIONEER is a European Network of Excellence for Big Data in Prostate Cancer, consisting of 34 private and public stakeholders in prostate cancer research and clinical care from across 9 countries.
Continued Growth of DEFINITY and Expansion of Our Ultrasound Microbubble Franchise
We believe the market opportunity for our ultrasound microbubble enhancing agent, DEFINITY, continues to be significant. DEFINITY has been our fastest growing and highest margin commercial product. We anticipate DEFINITY sales will continue to grow in the future. As we continue to educate the physician and healthcare provider community about the benefits and risks of DEFINITY, we believe we will be able to continue to grow the appropriateincrease use of DEFINITY through continued education of physicians and healthcare providers about the benefits of ultrasound enhancing agents in suboptimal echocardiograms. In aThe U.S. market withcurrently has three echocardiography ultrasound enhancing agents approved by the FDA,FDA; we estimate that DEFINITY had overwill continue to hold at least an 80% share of the market as of December 31, 2021.U.S. segment for ultrasound enhancing agents in echocardiography procedures.
As we continue to pursue expandinggrow our microbubble franchise, our activities include:
Patents - We continue to actively pursue additional patents in connection with DEFINITY and DEFINITY RT, both in the U.S. and internationally. In the U.S. for DEFINITY, we have foursix Orange Book-listed method of usemethod-of-use patents, one of which expires in 2035 and threefive of which expire in 2037, as well as additional manufacturing patents that are not Orange Book-listed expiring in 2023 and 2037. In the U.S. forFor DEFINITY RT, we have fiveeight Orange Book-listed patents, including atwo composition of matter patentpatents which expiresexpire in 2035.

The RFID tag, which expires in 2037; we have submitted additionalis affixed to the vial label, enables the DEFINITY vial to be appropriately activated with the VIALMIX RFID patent applications in major markets throughout the world.activation device.
Hatch-Waxman Act - Even though our longest duration Orange Book-listed DEFINITY patent extends until March 2037, because our Orange Book-listed composition of matter patent expired in June 2019, we may face generic DEFINITY challengers in the near to intermediate term. Under the Hatch-Waxman Act, the FDA can approve Abbreviated New Drug Applications (“ANDAs”) for generic versions of drugs if the ANDA applicant demonstrates, among other things, that (i) its generic candidate is the same as the innovator product by establishing bioequivalence and providing relevant chemistry, manufacturing and product data, and (ii) either the marketing of that generic candidate does not infringe the Orange Book-listed patent(s) or the Orange Book-listed patent(s) is invalid. Similarly, the FDA can approve a Section 505(b)(2) NDA from an applicant that relies on some of the information required for marketing approval to come from studies which the applicant does not own or have a legal right of reference. With respect to the Orange Book-listed patent(s) covering an innovator product, the ANDA applicant or the Section 505(b)(2) applicant (if relying on studies related to the innovator product) (together, the “Applicant”) must give a notice (a “Notice”) to the innovator of its certification that its generic candidate will not infringe the innovator’s Orange Book-listed patent(s) or that the Orange Book-listed patent(s) is invalid. The innovator can then file suit against the Applicant within 45 days of receiving the Notice, and FDA approval to commercialize the generic candidate will be stayed (that is, delayed) for up to 30 months (measured from the date on which a Notice is received) while the patent dispute between the innovator and the Applicant is resolved in court. The 30-month stay could potentially expire sooner if the courts determine that no infringement had occurred or that the challenged Orange Book-listed patent is invalid or if the parties otherwise settle their dispute.
As of the date of filing of this Annual Report on Form 10-K, we have not received any Notice from an Applicant. If we were to (i) receive any such Notice in the future, (ii) bring a patent infringement suit against the Applicant within 45 days of receiving that Notice, and (iii) successfully obtain the full 30-month stay, then the Applicant would be precluded from commercializing a generic version of DEFINITY prior to the expiration of that 30-month stay period and, potentially, thereafter, depending on how the patent dispute is resolved. Solely by way of example and not based on any knowledge we currently have, if we received a Notice from an Applicant in March 2022 and the full 30-month stay were obtained, then the Applicant would be precluded from commercialization until at least September 2024. If we received a Notice some number of months in the future and the full 30-month stay were obtained, the commercialization date would roll forward in the future by the same number of months. In the event a 505(b)(2) applicant does not rely on studies related to the innovator product, the 30-month stay would not apply, but additional clinical studies may be required.
DEFINITY RT -DEFINITY RT became commercially available in the fourth quarter of 2021. A modified The formulation of DEFINITY that we have branded as DEFINITY RT allows both storage and shipment at room temperature DEFINITY RTand provides clinicians an additional choice and allows for greater utility of this formulationuse in broader clinical settings. Given its physical characteristics, we believe DEFINITY RT is also well-suited for inclusion in kits requiring microbubbles for other indications and applications (including in kits developed by third parties of the type described further in the paragraph entitled “Microbubble Franchise” below).
Expansion of Strategic Partnerships and Other Revenue
We continue to seek ways to further increase the overall value of our portfolio of products and product candidates. We are evaluating a number of different opportunities to collaborate, in-license or acquire additional products, product candidates, businesses and technologies to drive our future growth. In particular, we are focused on late-stage radiopharmaceutical therapeutic and diagnostic product opportunities in oncology and other strategic areas that will complement our existing portfolio.
Our Strategic Partnerships and Other Revenue category includes our Strategic Partnerships, Pharma Solutions, and Digital Solutions businesses and is focused on enabling precision medicine with biomarkers and digital solutions.

The RFID tag,co-funding of our pipeline through collaborations, embed our technologies in the clinical ecosystem and establish the clinical utility of product candidates and research tools in our pipeline. Our Biomarkers are intended to support patient selection and the monitoring of disease progression. For example, piflufolastat F 18 is currently being used by Curium and Regeneron in those companies’ prostate cancer therapeutic drug development programs, and was also used in the development of PNT2002. Our acquisition of Cerveau in February 2023 added MK-6240 to our biomarker portfolio. MK-6240 is currently being used in more than ninety active clinical trials for several Alzheimer’s disease therapeutic candidates. Most recently, in collaboration with Ratio, we completed a Phase 1 study for LNTH-1363S, our novel fibroblast activation protein, alpha targeted, copper-64 labeled PET imaging agent candidate, to evaluate the pharmacokinetics, biodistribution and radiation dosimetry in adult healthy volunteers and plan to initiate a Phase 1/2a study in patients in 2024.
With respect to our Microbubble Platform, we generally enter into collaborations with partners that are designed to include our microbubble as part of a kit used with our partner’s medical device for therapeutic applications. In these collaborations, our microbubble is intended to be used as a vehicle to deliver a therapeutic drug.
Digital Solutions – Our Digital Solutions are designed to enhance imaging value and the throughput, reproducibility and reliability of image analysis, as well as to inform treatment selection and response to therapy. Our Digital Solutions include aPROMISE and aBSI (as defined below), both of which are FDA cleared and CE marked. aPROMISE, which is affixedcurrently sold as PYLARIFY AI in the U.S., is artificial intelligence medical device software that is designed to allow healthcare professionals and researchers to perform standardized quantitative assessment of PSMA PET/CT images in prostate cancer, including those images obtained by using PYLARIFY. Automated Bone Scan Index (“aBSI”) automatically calculates the vial label, enablesdisease burden of prostate cancer by detecting and classifying bone scan tracer uptakes as metastatic or benign lesions using an artificial neural network.

We offer our Digital Solutions to be appropriately activated with the VIALMIX RFID activation device.HCPs for clinical use and to pharmaceutical companies for development purposes, and in some cases, we also obtain clinical imaging data that we may use to further develop artificial intelligence solutions.
Global Mo-99 Supply
We currently have Mo-99 supply agreements with Institute for Radioelements (“IRE”), running through December 31, 2022,2024, with auto-renewal provisions andthat are terminable upon notice of non-renewal, and with NTP Radioisotopes (“NTP”), acting for itself and on behalf of its subcontractor, the Australian Nuclear Science and Technology Organisation (“ANSTO”), running through March 31, 2022, and for which we are currently negotiating an extension. We also have a Xenon supply agreement with IRE which runs through December 31, 2023, with auto-renewal provisions and terminable upon notice of non-renewal.2024.
Although we believe we have athe most globally diverse Mo-99 supply with IRE in Belgium, NTP in South Africa, and ANSTO in Australia, we still face supplier and logistical challenges in our Mo-99 supply chain. The NTP processing facility had periodicWhen one supplier experiences outages, in 2017, 2018 and 2019. When NTP was not producing, we reliedgenerally rely on Mo-99 supply from both IRE and ANSTOthe other suppliers to limit the impact of the NTP outages. In 2019 and 2020, ANSTO experienced multiple facility issues that resulted in ANSTO outages and volume limitations, during which timeWe believe we relied on IRE and NTP to limit the impact of those outages and limitations. Because of the COVID-19 pandemic, we experienced challenges receiving regularly scheduled orders of Mo-99 from our global suppliers, particularly in the second quarter of 2020. We continue toeffectively manage these various supply chain challenges, but depending on reactor and processor schedules and operations, at times we have not been able to fill some or all of the demand for our TechneLite generators on certain manufacturing days. A prolonged disruption of service from one of our three Mo-99 processing sites or one of their main Mo-99-producing reactors could have a substantial negative effect on our business, results of operations, financial condition and cash flows.
To augment our current supply of Mo-99, we have a strategic arrangement with SHINE Medical Technologies LLC (“SHINE”) for the future supply of Mo-99. Under the terms of the supply agreement, entered into in November 2014, SHINE will provide Mo-99 produced using its proprietary LEU-solution technology for use in our TechneLite generators once SHINE’s facility becomes operational and receives all necessary regulatory approvals, which SHINE now estimates will occur in 2023. The term of this arrangement provides for three years of supply of Mo-99. However, we cannot assure you that SHINE will be able to produce commercial quantities of Mo-99 for our business, or that SHINE together with our current suppliers will be able to deliver a sufficient quantity of Mo-99 to meet our needs.

Jubilant HollisterStier (“JHS”) is currently a significant supplier of DEFINITY and our sole source manufacturer of NEUROLITE, CardioliteCARDIOLITE and evacuation vials,vials. Our manufacturing and supply agreement with JHS (the “JHS MSA”) runs through December 31, 2027 and can be further extended by mutual agreement of the latter being an ancillary componentparties. The JHS MSA requires us to purchase from JHS specified percentages of our total requirements for our TechneLite generators.DEFINITY, as well as specified quantities of NEUROLITE, CARDIOLITE and evacuation vial products, each year during the contract term. Either party can terminate the JHS MSA upon the occurrence of certain events, including the material breach or bankruptcy of the other party. In addition to JHS, we rely on SBL as our sole source manufacturer of DEFINITY RT. Our new manufacturing agreement with JHS relating to DEFINITY, NEUROLITE and Cardiolite expires in December 2027.
In 2021, we have constructedcompleted the construction of a specialized in-house manufacturing facility at our North Billerica campus for purposesto produce the formulation of producing DEFINITY and, potentially, other sterile vial products.that requires refrigerated storage. On February 22, 2022, we received FDA approval of our sNDA,supplemental new drug application authorizing commercial manufacturing of DEFINITY at our new facility. DEFINITY manufactured at this facility became commercially available on February 23, 2022. We believe this investment will allow us to better manage DEFINITY manufacturingprovides supply chain redundancy, improved flexibility and inventory, reduce ourreduced costs in a potentially more price competitive environment, and provide us with supply chain redundancy.environment.
Radiopharmaceuticals are decaying radioisotopes with half-lives ranging from a few hours to several days. These productsRadiopharmaceutical finished goods, such as doses of PYLARIFY, cannot be kept in inventory because of their limited shelf lives and are subject to just-in-time manufacturing, processing and distribution, which takes place at our 54 PMF manufacturing sites across the U.S., with respect to PYLARIFY, and at our facilities in North Billerica, Massachusetts, and Somerset, New Jersey.
COVID-19 Pandemic
The global COVID-19 pandemic has had, and may continue to have, a material impact on our business. Towards the end of the first quarter of 2020 we began to experience, and through the date of this filing we are continuing to experience, impactswith respect to our businessTechneLite generators and operations related to the COVID-19 pandemic, including the impact of hospital staffing challenges, vaccination mandates, employee absences due to illness, and a decline in the volume of certain procedures and treatments using our products.
Although some of the restrictions, including stay-at-home mandates, imposed in response to the COVID-19 pandemic have been lifted in much of the U.S., and there has been a rapid rollout and development of multiple vaccines and boosters, the resurgence of COVID-19 infections continued to impact certain aspects of our business during the fourth quarter of 2021. For example, we believe sales of DEFINITY were impacted by hospital nursing and sonographer shortages, and sales of AZEDRA were impacted by treatment capacity constraints in hospitals, treatment deferrals and cancellations by patients, and access restrictions by hospitals. In addition, there has been a substantial reduction in pulmonary ventilation studies in which our product, Xenon is used because of institutional concerns and professional society guidelines relating to the possible spread of COVID-19 to technicians and other patients, because

Xenon is both inhaled and exhaled by the patient. Our Xenon sales through the fourth quarter of 2021 continued to be at reduced levels, we expect these reduced levels to continue for at least as long as COVID-19 precautions remain in place, and we can give no assurance that Xenon sales will return to historic levels.
The pandemic could still have a future negative impact on our business, particularly if there are additional resurgences as a result of mutations or other variations to the virus that further increase its communicability or its impact on certain populations, geographic regions and the healthcare system, including elective procedures and hospital access.

As we continue to pursue expanding our strategic partnerships, our Pharma ServicesSolutions activities and strategic partnerships in oncology include:
Prostate Cancer - Weare designed to enable precision medicine using biomarkers and digital solutions that augment diagnostic productivity. For example, in prostate cancer, we collaborate with pharmaceutical companies by supplying them with piflufolastat F 18 for use in their therapeutic drug development programs. For immuno-oncology, we intend to offer NM-01, a novel technetium-99m SPECT imaging agent that we are developing therapiesto assess PD-L1 expression in cancer cells, for potential use as an efficacy and diagnosticssafety biomarker in prostate cancer. In January 2022,immuno-oncology therapies. With respect to pan-oncology, we announced a collaboration with the Prostate Cancer Clinical Trial Consortium (“PCCTC”), a premier multicenter clinical research organization that specializes in prostate cancer research. The intent of the strategic collaboration is to integrate our AI platform into PCCTC studies to advance the development and validation of novel AI-enabled biomarkers. In September 2021, we entered into a development and commercialization collaboration with RefleXion Medical, Inc. to evaluateare further exploring the use of piflufolastat F 18 to enable real-time therapeutic guidance of biology-guided radiotherapy in prostate cancer using the RefleXion X1TM platform. Prior to 2021, we had also entered into several other agreements, including ones with Bayer, POINT Biopharma and Regeneron, under which we supply piflufolastat F 18 in connection with their clinical studies, and Curium, under which we licensed exclusive rights to Curium to develop and commercialize piflufolastat F 18 in Europe.
Immuno-Oncology - In May 2019, we entered into a strategic collaboration and license agreement with NanoMab, a privately-held biopharmaceutical company focused on the development of next generation radiopharmaceuticals for cancer precision medicine.
Pan-Oncology - In March 2021, we acquired from Ratio Therapeutics LLC (previously Noria Therapeutics, Inc.) exclusive, worldwide rights to NTI-1309,LNTH-1363S as an innovative imaging biomarker that targets fibroblast activation protein, an emerging target with broad potential imaging applicability and use in oncology. Upon further clinical development, we will assess options to bring NTI-1309 to market as a diagnostic or potentially a therapeutic product.protein.
Microbubble Franchise
In addition, as described above, we continue to expand our microbubble franchise. In April 2021, we announced a strategic collaboration with Allegheny Health Network (“AHN”), which will useSome of our microbubbles in combination with AHN’s ultrasound-

assisted non-viral gene transfer technology for the development of a proposed treatment of xerostomia. Xerostomia is a lack of saliva production leading to dry mouth and has a variety of causes, including radiotherapy and chemotherapy, the chronic use of drugs and rheumatic and dysmetabolic diseases. Prior to 2021, we entered into microbubble collaborations are with the following parties: (i) Cerevast Medical, Inc. (“Cerevast”), in which our microbubbles will be used in connection with Cerevast’s ocular ultrasound device to improve blood flow in occluded retinal veins in the eye; (ii) CarThera SAS, for the use of our microbubbles in

combination with SonoCloud, a proprietary implantable device in development for the treatment of recurrent glioblastoma; and (iii) Insightec Ltd. (“Insightec”), which will use our microbubbles in connection with the development of Insightec’s transcranial guided focused ultrasound device for the treatment of glioblastoma as well as other neurodegenerative conditions.conditions; (iv) Allegheny Health Network (“AHN”), which will use our microbubbles in combination with AHN’s ultrasound-assisted non-viral gene transfer technology for the development of a proposed treatment of xerostomia; and (v) SonoThera, which will use our microbubbles in combination with their ultrasound-guided, non-viral, gene therapy platform and treatments.
flurpiridaz
In September 2022, we announced with our strategic partner GE Healthcare Limited (“GE Healthcare”) that the recent Phase 3 clinical trial of our investigational radiotracer, flurpiridaz, had met its co-primary endpoints of exceeding a 60% threshold for both sensitivity and specificity for detecting coronary artery disease (“CAD”). The findings, shared at an American Society of Nuclear Cardiology conference, also demonstrated that cardiac PET imaging with flurpiridaz has higher diagnostic efficacy and image quality in patients with suspected CAD, compared with single photon emission computed tomography (“SPECT”) Myocardial Perfusion Imaging (“MPI”), the predominant procedure currently used in nuclear cardiology. We believe SPECT MPI represents approximately 6 million procedures per year in the U.S.
Under a Collaboration and License Agreement we entered into with GE Healthcare in 2017, GE Healthcare has led the funding and development of flurpiridaz, and, if the imaging agent is approved, will have the global commercialization rights for it. GE Healthcare recently announced that it had filed an NDA with the FDA for flurpiridaz. Assuming regulatory approval, we anticipate commercialization by GE Healthcare beginning in the second half of 2024. If flurpiridaz receives regulatory approval and is commercially successful, we will receive:
• up to $60 million in regulatory and sales milestone payments,
• tiered double-digit royalties on U.S. sales., and
• mid-single digit royalties on sales outside of the U.S.
Generally, our costs in connection with the strategic partnerships relate to intellectual property, the supply of drug and other ancillary expenses and the benefits can include possible supply, milestone and royalty payments, additional intellectual property rights and strategic relationships. For flurpiridaz, under the Collaboration and License Agreement, we retained ownership of all of the licensed intellectual property and bear the cost of patent prosecution and maintenance. We can give no assurance as to if or when or if any of these collaborations and other new initiatives, including our collaboration for flurpiridaz, will be successful or accretive to earnings.

Revenues
We classify our revenues into three product categories: precision diagnostics, radiopharmaceutical oncology,Radiopharmaceutical Oncology, Precision Diagnostics, and strategic partnershipsStrategic Partnerships and other revenue.Other Revenue. Radiopharmaceutical Oncology consists of PYLARIFY and AZEDRA. In 2023, we announced our decision to discontinue the production and promotion of AZEDRA and we do not expect AZEDRA to contribute to the business after the first quarter of 2024. Precision diagnosticsDiagnostics includes DEFINITY, TechneLite and other diagnostic imaging diagnostic products. Radiopharmaceutical oncology consistsStrategic Partnerships and Other Revenue primarily of PYLARIFYincludes out-licensing arrangements and AZEDRA. Strategic partnerships and other revenue includes partnerships that focus on facilitating precision medicine through the use of biomarkers, digital solutions and radiotherapeutic platforms, and on our other products, such as RELISTOR.platforms.

The increase in revenues for the year ended December 31, 2021,2023, as compared to the prior year period, is primarily drivendue to increased PYLARIFY and DEFINITY sales volume and RELISTOR milestone achievement of $15.0 million earned in the fourth quarter of 2023. The increase is offset, in part, by a decrease in Strategic Partnerships and Other Revenue due to the commercial launch of PYLARIFY, as well as increases in DEFINITY and TechneLite volume period over period as a result ofrevenue recognized from the COVID-19 pandemicNovartis licensing agreement in the prior year as well asdescribed further under Note 3, “Disaggregation of Revenue” below and the additionsale of the Progenics product portfolio, including RELISTOR. These increases are partially offset by continued COVID-19 related reduced volumes in our sales of Xenon throughout 2021 and the divestiture of our Puerto Rico business during the first quarter of 2021.RELISTOR royalty revenue asset.
Rebates and Allowances
Estimates for rebates and allowances represent our estimated obligations under contractual arrangements with third parties. Rebate accruals and allowances are recorded in the same period the related revenue is recognized, resulting in a reduction to revenue and the establishment of a liability which is included in accrued expenses. These rebates and allowances result from performance-based offers that are primarily based on attaining contractually specified sales volumes and growth, Medicaid rebate programs for our products, administrative fees of group purchasing organizations and certain distributor related commissions. The calculation of the accrual for these rebates and allowances is based on an estimate of the third party’s buying patternsthird-party’s expected purchases and the resulting applicable contractual rebate to be earned over a contractual period.

Income Tax (Benefit) Expense
The income tax benefit of $3.8 million for the year ended December 31, 2021 was primarily due to incurred losses before tax, the release of a portion of our uncertain tax positions, stock compensation deductions, and tax credits,partially offset by non-deductible expenses related to the changes in fair value of contingent assets and liabilities, the accrual of interest associated with uncertain tax positions, and the impact of an increased effective state tax rate on our ending net deferred tax assets. income taxes.

Assuming that the receivable from BMS continues to be considered recoverable by us, there will be no effect on net income and no net cash outflows related to these liabilities. During 2023, the Company released a significant portion of its indemnified liability due to the settlement of these positions in certain states at a cost significantly less than our accrual resulting in $5.2 million (net of federal or state benefit) income tax benefit. Refer to Note 5, Income Taxes.
The income tax expense of $2.0 million for the year ended December 31, 2020 was primarily due to the accrual of interest associated with uncertain tax positions and the impact of non-deductible acquisition costs, offset by the tax benefits on losses generated in the period, the recognition of the deferred tax asset on held for sale assets, and tax credits.
We regularly assess our ability to realize our deferred tax assets. Assessing the realizability of deferred tax assets requires management judgment. In determining whether our deferred tax assets are more-likely-than-not realizable, we evaluate all available positive and negative evidence, and weigh the objective evidence and expected impact. We continue to record a valuation allowance against certain of our foreign net deferred tax assets and a small component of our domestic deferred tax assets.

Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10-K for the fiscal year ended December 31, 2020,2022, filed with the SEC on February 25, 2021.23, 2023.
Net Cash Provided by Operating Activities
Net cash provided by operating activities of $53.9$305.3 million during the year ended December 31, 2023 was primarily comprised of net lossincome adjusted for the net effect of non-cash items such as impairment of long-lived assets, depreciation, amortization and accretion expense, gain on sale of our RELISTOR royalty asset, deferred income taxes, and stock-based compensation expense. The primary working capital sources of cash were the timing of payments to large vendors. The primary working capital uses of cash were a decrease to accruals related to the CVR payment, an increase in trade receivables associated primarily with the increase in PYLARIFY revenues, and an increase in inventory related to the timing of batch processes.
Net cash provided by operating activities of $281.8 million during the year ended December 31, 2022 was primarily comprised of net income adjusted for charges incurred in connection with acquired IPR&D and the net effect of non-cash items such as depreciation, amortization and accretion expense, the change in fair value of contingent assets and liabilities of $72.4$34.7 million (refer to Note 4, “Fair Value of Financial Instruments”, for further details on contingent consideration liabilities, including CVRs)., and stock-based compensation expense. The primary working capital sources of cash were the timing of payments to large vendors as well as an increase in billingsaccruals associated with PYLARIFY sales. The primary working capital useuses of cash were an increase in trade receivables from timing of sale orders and an increase in collection period as well as the timing of inventory purchases.
Net cash provided by operating activities of $16.4 million in the year ended December 31, 2020 was drivenassociated primarily by a net loss of $13.5 million, a net decrease of $22.4 million related to movements in our working capital accounts during the period and a net decrease of $2.0 million in the fair value of contingent assets and liabilities offset by $24.7 million of depreciation, amortization and accretion expense, stock-based compensation expense of $14.1 million, impairment of long-lived assets of $9.9 million and a loss on disposal of assets of $2.3 million. The overall decreases in cash from our working capital accounts were primarily driven bywith the increase in accounts receivable due to the Progenics Acquisition and increase in collection period as well as change in inventory related to the COVID-19 impact on products and the timingPYLARIFY revenues.

Net Cash Used in(Used in) Provided by Financing Activities
Net cash used in financing activities during the year ended December 31, 20212023 is primarily attributable to the payments on long-term debt and other borrowings of $43.3 million related to the 2019 Term Facility and Royalty-Backed Loan, including a voluntary repayment of the outstanding principal on the Royalty-Backed Loan and payments for minimum statutory tax withholding related to net share settlement of equity awards of $2.0$14.4 million and the CVR initial valuation as of June 30, 2020 of $3.7 million, offset by proceeds of $5.3$3.8 million from stock option exercises.
Net cash used inprovided by financing activities during the year ended December 31, 20202022 is primarily attributable to the proceeds of $557.8 million received from the issuance of the Notes, proceeds of $7.5 million from stock option exercises and proceeds of $5.6 million from the voluntarily terminated interest rate swap contracts in connection with the refinancing of debt. These amounts were offset by payments on long-term debt and other borrowings of $15.5$175.0 million, related to the 2019 Term Facility and Royalty-Backed Loan (defined below), equity issuance costs related to the Progenics Acquisitionrepurchase of $3.8common stock of $75.0 million and payments for minimum statutory tax withholding related to net share settlement of equity awards of $2.1$7.8 million.

Please refer to Note 13,12, “Long-Term Debt, Net, and Other Borrowings” for further details on the 20192022 Facility.
On June 19, 2020, we amended our 2019 Credit Agreement (the “Amendment”) as a result of the impact of the COVID-19 pandemic on our business and operations and the near-term higher level of indebtedness resulting from our decision not to immediately repay the Progenics debt secured by the RELISTOR royalties following the Progenics Acquisition.
The Amendment provides for, among other things, modifications to our financial maintenance covenants. The covenant related to Total Net Leverage Ratio (as defined in the 2019 Credit Agreement) was waived from the date of the Amendment through December 31, 2020. The maximum total net leverage ratio and interest coverage ratio permitted by the financial covenant is displayed in the table below:

As of December 31, 2021,2023, we were in compliance with all financial and other covenants under the 20192022 Credit Agreement.
Under the 2019 Credit Agreement, loans bear interest at LIBOR plus a spread that ranges from 1.50% to 3.00% or the Base Rate plus a spread that ranges from 0.50% to 2.00%, and the commitment fee ranges from 0.15% to 0.40%,On December 8, 2022, we issued $575.0 million in each case based on our Total Net Leverage Ratio.

Funding Requirements
Our future capital requirements will depend on many factors, including:
The level of product sales and the pricing environment of our currently marketed products, particularly PYLARIFY and DEFINITY, PYLARIFY, as well as any additional products that we may market in the future, including decreased product sales resulting from the COVID-19 pandemic;future;
Revenue mix shifts and associated volume and selling price changes that could result from contractual status changes with key customers and additional competition;
The continued costs of the PYLARIFY commercial launchongoing commercialization of our products;
Our investment in the further clinical development and our ability to successfully commercialize PYLARIFY;commercialization of products and development candidates, including PNT2002, PNT2003, 1095 and MK-6240;
The costs of acquiring or in-licensing, developing, obtaining regulatory approval for, and commercializing, new products, businesses or technologies, including any potential related milestone or royalty payments, together with the costs of pursuing opportunities that are not eventually consummated;
Our investment in the further clinical development and commercialization of products and development candidates, including AZEDRA, 1095, and LMI 1195;
The costs of investing in our facilities, equipment and technology infrastructure;
The costs and timing of establishing or amending manufacturing and supply arrangements for commercial supplies of our products and raw materials and components;
Our ability to have productproducts manufactured and released from JHS and other manufacturing sites in a timely manner in the future, or to begin and ramp up our manufacturing of DEFINITYmanufacture products at our in-house manufacturing facilityfacilities in an amountamounts sufficient to meet our supply needs;
The costs of further commercialization of our existing products, particularly in international markets, including product marketing, sales and distribution and whether we obtain local partners to help share such commercialization costs;
The extent to which we choose to establish collaboration, co-promotion, distribution or other similar arrangements for our marketed products;
The legal costs relating to maintaining, expanding and enforcing our intellectual property portfolio, pursuing insurance or other claims and defending against product liability, regulatory compliance, intellectual property or other claims;claims, including the patent infringement claim related to the filing of our ANDA for PNT2003;
The cost of interest on any additional borrowings which we may incur under our financing arrangements; and
The impact of sustained inflation on our costs of goods sold and operating expenses.
We are vulnerable to future supply shortages, especially for our single sourced products. Disruption in our financial performance could also occur if we experience significant adverse changes in product or customer mix, broad economic downturns, sustained inflation, adverse industry or company conditions or catastrophic external events, including pandemics such as COVID-19, natural disasters and political or military conflict. If we experience one or more of these events in the future, we may be required to further implement expense reductions, such as a delay or elimination of discretionary spending in all functional areas, as well as scaling back select operating and strategic initiatives.
If our capital resources become insufficient to meet our future capital requirements, we would need to finance our cash needs through public or private equity offerings, debt financings, assets securitizations, sale-leasebacks or other financing or strategic alternatives, to the extent such transactions are permissible under the covenants of our 20192022 Credit Agreement. Additional equity or debt financing, or other transactions, may not be available on acceptable terms, if at all. If any of these transactions require an amendment or waiver under the covenants in our 20192022 Credit Agreement, which could result in additional expenses associated with obtaining the amendment or waiver, we will seek to obtain such aan amendment or waiver to remain in compliance with those covenants. However, we cannot be assuredprovide assurance that such an amendment or waiver would be granted, or that additional capital will be available on acceptable terms, if at all.
At December 31, 2021,2023, our only current committed external source of funds is our borrowing availability under our 20192022 Revolving Facility. We had $98.5$713.7 million of cash and cash equivalents atas of December 31, 2021.2023. Our 20192022 Revolving Facility as amended, contains a number of affirmative, negative, reporting and financial covenants, in each case subject to certain exceptions and materiality thresholds. Incremental borrowings under the 20192022 Revolving Facility as amended, may affect our ability to comply with the covenants in the 2019 Facility, as amended, including the financial covenants restricting consolidated net leverage and interest coverage. Accordingly, we may be limited in utilizing the full amount of our 20192022 Revolving Facility as amended, as a source of liquidity.

The CVRs we issued in the Progenics Acquisition entitle holders thereof to future cash payments of 40% of PYLARIFY net sales over (i) $100.0 million in 2022 and (ii) $150.0 million in 2023, which, if payable, we currently intend to fund from our then-available cash. In no event will our aggregate payments under the CVRs, together with any other non-stock consideration treated as paid in connection with the Progenics Acquisition, exceed 19.9% (which we currently estimate could be approximately $100.0 million) of the total consideration we pay in the Progenics Acquisition. Refer to Note 4, “Fair Value of Financial Instruments”, for further details on contingent consideration liabilities.
Based on our current operating plans, including our prudent expense management in response to the COVID-19 pandemic, we believe our balance of cash and cash equivalents, which totaled $98.5$713.7 million as of December 31, 2021,2023, along with cash generated by ongoing operations and continued access to our 20192022 Revolving Facility, will be sufficient to satisfy our cash requirements over the next twelve months and beyond. Our material cash requirements include the following contractual and other obligations.
Debt
We completed a sale of $575.0 million in aggregate principal amount of the Notes due in 2027. As of December 31, 2021,2023, we had maturitiesno amounts of principal obligations related to our 2019 Term Facility for an aggregate principal amount of $175.0 million, with $11.3 million payabledue within the next twelve months. Future interest payments associated with the 2019 Term FacilityNotes total $8.3$60.0 million, with $3.6$15.1 million payable within twelve months.
Leases
We have operating lease arrangements for certain facilities, including corporate and manufacturing space. As of December 31, 2021,2023, we had fixed operating lease payment obligations of $22.0$99.5 million, with $2.4$4.6 million payable within twelve months.
We have lease arrangements for certain equipment. As of December 31, 2021,2023, we had fixed finance lease payment obligations of $0.8$1.7 million, with $0.4$0.8 million payable within twelve months.
Purchase Obligations
We have purchase obligations that primarily consist of noncancelable obligations related to minimum quantities of goods or services that have been committed to be purchased on an annual basis. As of December 31, 2021,2023, we had minimum purchase obligations of $6.5$10.9 million, with $3.5$2.7 million due within twelve months.
License Agreements
We have entered into license agreements in which fixed payments have been committed to be paid on an annual basis. As of December 31, 2021,2023, we had no amount of fixed license payments of $0.3 million, with $0.1 million due within twelve months. These amounts do not include potential milestone or contractual payment obligations contingent upon the achievement or occurrence of future milestones or events under our license agreements, because they are contingent and the amounts and timing of such potential obligations are unknown or uncertain. We may be required to pay additional amounts up to approximately $170.5$264.4 million in contingent payments under our license agreements.
Asset Acquisitions
During 2022, we entered into the POINT License Agreements, in which we made upfront payments of $260.0 million, and under which we may make additional milestone payments. The additional milestone payments are based on FDA approval and net sales and commercial milestones. Under the terms of the PNT2002 License Agreement, we have the potential to pay up to an additional $281.0 million in milestone payments and up to $1.3 billion in sales milestone payments upon the achievement of specified annual sales thresholds. Under the terms of the PNT2003 License Agreement, we have the potential to pay an additional $34.5 million in milestone payments and up to $275.0 million in sales milestone payments upon the achievement of specified annual sales thresholds. In total, we may be required to pay up to approximately $1.8 billion related to the asset acquisition. As of December 31, 2023, these contingent payments were not expected to be payable due to the uncertainty around the timing of the future cash flows.
On February 6, 2023, the Company acquired Cerveau and made an upfront payment of approximately $35.3 million to the Selling Stockholders. The Company paid the Selling Stockholders an additional $10.0 million in May 2023 upon the successful completion of a technology transfer. The Company could pay up to an additional $51.0 million in milestone payments upon achievement of specified U.S. regulatory milestones related to MK-6240. The Selling Stockholders are also eligible to receive up to $1.2 billion in sales milestone payments upon the achievement of specified annual commercial sales thresholds of MK-6240 in the event the Company pursues commercialization, as well as up to $13.5 million in research revenue milestones upon achievement of specified annual research revenue thresholds. Additionally, the Company will pay to the Selling Stockholders up to double-digit royalty payments for research revenue and commercial sales. As of December 31, 2023, these contingent payments were not expected to be payable due to the uncertainty around the timing of the future cash flows.
Other Long-Term Liabilities
Our other long-term liabilities in the consolidated balance sheet include the fair values of contingent consideration liabilities including CVRs and contingent consideration liabilities related to a previous acquisition completed by Progenics in 2013. We may be required to pay up to approximately $100.0 million related to the CVRs and approximately $85.0 million related to the contingent consideration. As of December 31, 2021,2023, these contingent payments were not expected to be payable within twelve months due to the uncertainty around the timing of the future cash flows.

Table of Contents

Our other long-term liabilities in the consolidated balance sheet include unrecognized tax benefits and related interest and penalties. As of December 31, 2021,2023, we had unrecognized tax benefits of $20.9$3.2 million, which included interest and penalties, classified as noncurrent liabilities. At this time, we are unable to make a reasonably reliable estimate of the timing of payments in individual years in connection with these tax liabilities.
Asset Retirement Obligation
We are required to provide the Massachusetts Department of Public Health and the New Jersey Department of Environmental Protection financial assurance demonstrating our ability to fund the decommissioning of our North Billerica, Massachusetts and Somerset, New Jersey production facilities, respectively, upon closure, although we have no current plans to close the facilities.closure. We have provided this financial assurance in the form of a $28.2$30.3 million surety bond (the “Surety Bond”). As of December 31, 2021,2023, the liability, which was approximately $20.8$22.9 million, was measured at the present value of the obligation expected to be incurred of approximately $26.4$25.1 million. These contingent payments are not expected to be payable within twelve months due to the uncertainty around the timing of the future cash flows related to the decommissioning of our radioactive operations.
72

Table of Contents

Off-Balance Sheet Arrangements
As noted above, we have provided the Surety Bond to the Massachusetts Department of Public Health and New Jersey Department of Environmental Protection.
Since inception, we have not engaged in any other off-balance sheet arrangements, including structured finance, special purpose entities or variable interest entities.
Effects of Inflation
We do not believe that inflation has had a significant impact on our revenues or results of operations. We expect our cost of product sales and other operating expenses will change in the future in line with periodic inflationary changes in price levels. Because we intend to retain and continue to use our property and equipment, we believe that the incremental inflation related to the replacement costs of those items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation and contract services, which could increase our level of expenses and the rate at which we use our resources. While we generally believe that we will be able to offset some of the effect of price-level changes by adjusting our product prices and implementing operating efficiencies, any material unfavorable changes in price levels could have a material adverse effect on our financial condition, results of operations and cash flows.
Recent Accounting Standards
Refer to Note 2, “Summary of Significant Accounting Policies,” in the accompanying consolidated financial statements located under Item 8 of this Annual Report on Form 10-K for information regarding recently issued accounting standards that may have a significant impact on our business.
Critical Accounting EstimatesPolicies
The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements require us to make estimates and judgments that affect our reported assets and liabilities, revenues and expenses, and other financial information. Actual results may differ materially from these estimates under different assumptions and conditions. In addition, our reported financial condition and results of operations could vary due to a change in the application of a particular accounting standard.
We believe the following represent our critical accounting estimates used in the preparation of our financial statements.
Revenue from Contracts with Customers
Revenue is measured based on a consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. We recognize revenue when we satisfy our performance obligations by transferring control over products or services to our customers. The amount of revenue we recognize reflects the consideration to which we expect to be entitled to receive in exchange for these goods or services. To achieve this core principle, we apply the following five steps: (1) identify the contracts with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) we satisfy performance obligations.
We derive our revenues through arrangements with customers for product sales as well as licensing and royalty arrangements. We sell our products primarily to clinics, distributors, group practices, hospitals, integrated delivery networks,independent diagnostic testing facilities, and radiopharmacies, and we consider customer purchase orders, which in some cases are governed by master sales or group purchasing organization agreements, to be contracts with
74

Table of Contents

our customers. In addition to these arrangements, we also enter into licensing agreements under which we license certain rights to third parties. The terms of these arrangements typically include payment to us of one or more of the following: non-refundable, up-front license fees; development, regulatory and commercial milestone payments; and royalties on net sales of licensed products. We analyze various factors requiring management judgment when applying the five-step model to our contracts with customers.
Our product revenues are recorded at the net sales price (transaction price), which represents our sales price less estimates related to reserves which are established for items such as discounts, returns, rebates and allowances that may be provided for in certain contracts with our customers. Judgment is used in determining and updating our reserves on an ongoing basis, and where appropriate, these estimates take into consideration a range of possible outcomes which are probability-weighted for relevant factors such as our historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, these reserves reflect our best estimates of the amount of consideration to which it is entitled based on the terms of the contract. Actual amounts of consideration ultimately received may differ from our estimates.
73

Table of Contents

For our licensing and royalty arrangements, we use judgment in determining the number of performance obligations in a license agreement by assessing whether the license is distinct or should be combined with another performance obligation as well as the nature of the license. As part of the accounting for these arrangements, we develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in a contract. These key assumptions may include market conditions, reimbursement rates for personnel costs, development timelines and probabilities of regulatory success.
Business Combinations
We account for business combinations using the acquisition method of accounting. We recognize the assets acquired and liabilities assumed in business combinations on the basis of their fair values at the date of acquisition. We assess the fair value of assets acquired, including intangible assets, and liabilities assumed using a variety of methods. Each asset acquired and liability assumed is measured at fair value from the perspective of a market participant. The method used to estimate the fair values of intangible assets incorporates significant assumptions regarding the estimates a market participant would make in order to evaluate an asset, including a market participant’s use of the asset and the appropriate discount rates. Acquired in-process research and development (“IPR&D”)&D is recognized at fair value and initially characterized as an indefinite-lived intangible asset, irrespective of whether the acquired IPR&D has an alternative future use. Any excess purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Transaction costs and restructuring costs associated with a business combination are expensed as incurred.
The fair values assigned to tangible and intangible assets acquired and liabilities assumed are based on our estimates and assumptions, as well as other information we have compiled, including valuations that utilize customary valuation procedures and techniques. If the actual results differ from the estimates and assumptions used in these estimates, it could result in a possible impairment of the intangible assets and goodwill, a required acceleration of the amortization expense of finite-lived intangible assets or the recognition of additional consideration, which would be expensed.
During the measurement period, which extends no later than one year from the acquisition date, we may record certain adjustments to the carrying value of the assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, all adjustments are recorded in the consolidated statements of operations as operating expenses or income.
Intangible and Long-Lived Assets
We test intangible and long-lived assets for recoverability whenever events or changes in circumstances suggest that the carrying value of an asset or group of assets may not be recoverable. We measure the recoverability of assets to be held and used by comparing the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset. If those assets are considered to be impaired, the impairment equals the amount by which the carrying amount of the assets exceeds the fair value of the assets. Any impairments are recorded as permanent reductions in the carrying amount of the assets. Long-lived assets, other than goodwill and other intangible assets, that are held for sale are recorded at the lower of the carrying value or the fair market value less the estimated cost to sell.
Intangible assets, consisting of trademarks, customer relationships, currently marketed products, licenses and developed technology are amortized in a method equivalent to the estimated utilization of the economic benefit of the asset.
Costs of IPR&D intangible assets acquired as part of an asset acquisition that have no alternative future use are expensed when incurred. Milestone payments made after regulatory approval are capitalized as an intangible asset and amortized over an estimated useful life of the product. Cash payments related to acquired IPR&D intangible assets are reflected as an investing cash flow in the Company's consolidated statement of cash flows.

Table of Contents

Our IPR&D representsintangible assets include intangible assets acquired in a business combination that are used in research and development activities but have not yet reached technological feasibility, regardless of whether they have alternative future use. The primary basis for determining the technological feasibility or completion of these projects is whether we have obtained regulatory approval to market the underlying products in an applicable geographic region. Because obtaining regulatory approval can include significant risks and uncertainties, the eventual realized value of the acquired IPR&D projects may vary from their fair value at the date of acquisition. We classify IPR&D intangible assets acquired in a business combination as an indefinite-lived intangible asset until the completion or abandonment of the associated research and development efforts. Upon completion of the associated research and development efforts, we will determine the useful life and begin amortizing the assets to reflect their use over their remaining lives. Upon permanent abandonment, we write-off the remaining carrying amount of the associated IPR&D intangible asset. We test our IPR&D intangible assets at least annually or when a triggering event occurs that could indicate a potential impairment and we recognize any impairment loss in our consolidated statements of operations.
Contingent Consideration Liabilities
The Progenics Acquisition included certain contingent consideration liabilities, including CVRs, as well as other contingent future payments. CVRs are based on net sales generated by PYLARIFY in both 2022 and 2023. Other contingent future payments are based on net sales targets for 1095 and AZEDRA and include a commercialization milestone for 1095. The estimated fair value of contingent consideration liabilities, initially measured and recorded on the acquisition date, are considered to be a Level 3 instrument and are reviewed quarterly, or whenever events or circumstances occur that indicate a change in fair value. The contingent
74

Table of Contents

consideration liabilities are recorded at fair value at the end of each reporting period with changes in estimated fair values recorded in general and administrative expenses in the consolidated statements of operations.
The estimated fair value is determined based on probability adjusted discounted cash flows or Monte Carlo simulation models that include significant estimates and assumptions pertaining to the period of expected milestone achievement, probability of success, discount rates and sales targets. The most significant unobservable inputs are the probabilities of achieving regulatory approval of the development projects and subsequent commercial success.
Significant changes in any of the probabilities of success would result in a significantly higher or lower fair value measurement. Significant changes in the probabilities as to the periods in which milestones will be achieved would result in a significantly lower or higher fair value measurement.

We are exposed to market risk from changes in interest rates and foreign currency exchange rates. We may from time to time use derivative financial instruments or other financial instruments to hedge these economic exposures related to foreign currencies. We do not hold or issue financial instruments for trading purposes.
Interest Rate Risk
Under our 2019 Facility, as amended, we have substantial variable rate debt. Fluctuations in interest rates may affect our business, financial condition, results of operations and cash flows. As of December 31, 2021, we had $175.0 million outstanding principal under our 2019 Term Facility with variable interest rates.
Furthermore, weWe are subject to interest rate risk in connection with our 20192022 Revolving Facility, which is variable rate indebtedness. Interest rate changes could increase the amount of our interest payments and thus negatively impact our future earnings and cash flows. As of December 31, 2021,2023, there was availability of $200.0$350.0 million on the 20192022 Revolving Facility. Any increase in the interest rate under the 20192022 Revolving Facility may have a negative impact on our future earnings to the extent we have outstanding borrowings under the 20192022 Revolving Facility.
We usehad used interest rate swaps to reduce the variability in cash flows associated with a portion of our forecasted interest payments on its variable rate debt. As of December 31, 2021, we had entered intoWe voluntarily terminated our interest rate swap contracts to fix the LIBOR rate on a notional amount of $100.0 million through May 31, 2024. The average fixed LIBOR rate on the interest rate swaps as of December 31, 2021 was approximately 0.82%. This agreement involves the receipt of floating rate amounts in exchange for fixed rate interest payments over the life of the agreement without an exchange of the underlying principal amount. Please refer to Note 14, “Derivative Instruments”, for further details on the interest rate swaps.
The effect of a 100 basis points adverse change in market interest rates on our 2019 Term Facility, in excess of applicable minimum floors, on our interest expense would be approximately $1.8 million excluding the impact of our interest rate swaps; including the impact of our interest rate swaps, the effect of a 100 basis point adverse change in market interest rates would be approximately $0.8 million.2, 2022.
Foreign Currency Risk
We face exposure to movements in foreign currency exchange rates whenever we, or any of our subsidiaries, enter into transactions with third parties that are denominated in currencies other than our, or that subsidiary’s, functional currency. Intercompany transactions between entities that use different functional currencies also expose us to foreign currency risk.
During the years ended December 31, 2021, 20202023, 2022 and 2019,2021, the net impact of foreign currency changes on transactions was a gainloss of less than $0.1 million, a loss of $0.3 million and a gain of less than $0.1$0.3 million, respectively. From time to time, we enter into foreign currency forward contracts primarily to reduce the effects of fluctuating foreign currency exchange rates. We may enter into additional foreign currency forward contracts when deemed appropriate. We do not enter into foreign currency forward contracts for speculative or trading purposes.
The Canadian dollar presents the primary currency risk on our earnings. At December 31, 2021,2023, a hypothetical 10% change in value of the U.S. dollar relative to the Canadian dollar would not have materially affected our financial instruments.

Valuation of Contingent Value Rights—Intangible Assets — Non-Cash Impairment Charge for AZEDRA Intangible Asset Group — Refer to Notes 1 and 4Note 10 to the financial statements
Critical Audit Matter Description
AsIn March 2023, the Company stopped all development activities in relation to a future indication associated with AZEDRA, which was classified as an in-process research and development (“IPR&D”) intangible asset. The asset group, which consisted of the IPR&D asset and a currently marketed product (the “AZEDRA intangible asset group”), was assessed for impairment. The Company considered several factors in estimating the future projections of revenues and cash flows of the AZEDRA intangible asset group as part of the acquisition of Progenics Pharmaceuticals, Inc. (“Progenics”) on June 19, 2020,impairment testing. The Company concluded that the Company issued contingent value rights (“CVRs”) to certain stockholders of Progenics entitling them to future cash payments of 40% of U.S. net sales generated by PYLARIFY in 2022 and 2023 in excess of $100.0 million and $150.0 million, respectively.
The estimatedcarrying amount exceeded the fair value of the CVRs was determined usingAZEDRA intangible asset group, which had no value. As a Monte-Carlo simulation model that included estimatesresult of such assessment, the Company recorded a non-cash impairment charge in research and assumptions pertainingdevelopment expenses relating to (1) the periodIPR&D asset and a non-cash impairment charge in cost of expected milestone achievement and net sales targets and (2) discount rates. The fair value determinationgoods sold relating to the currently marketed indication of these CVRs therefore required management to make estimates and assumptions relatedAZEDRA in the periods in which net sales targets will be achieved andconsolidated statement of operations for the selection of the discount rates.year ended December 31, 2023.
We identified management’s estimates of future projections of revenue and cash flows used to determine the valuationfair value of the contingent consideration liabilities relatedAZEDRA intangible asset group used to record the CVRsnon-cash impairment charge as a critical audit matter because of the significant estimates and assumptions usedmade by management to determine the fair value of these CVRs.

This required a high degree of auditor judgment and an increased extent of effort including the involvement of our valuation specialists, when performing audit procedures to evaluate the reasonableness of management’s estimates as to the period of expected milestone achievementfuture projections of revenues and net sales targets and the selection of the discount rates.cash flows.

Progenics Acquisition
On June 19, 2020 (the “Closing Date”), pursuant to the Amended and Restated Agreement and Plan of Merger, dated as of February 20, 2020 (the “Merger Agreement”), by and among Holdings, Plato Merger Sub, Inc., a wholly-owned subsidiary of Holdings (“Merger Sub”), and Progenics, Holdings completed the acquisition of Progenics by means of a merger of Merger Sub with and into Progenics, with Progenics surviving such merger as a wholly-owned subsidiary of Holdings (the “Progenics Acquisition”).

Please refer to Note 8, “Business Combinations”, for further details on the acquisition.
PYLARIFY Approval and Commercial Launch
On May 27, 2021, the Company announced that the FDA had approved PYLARIFY, a fluorine-18- (“F 18”) labeled PET imaging agent targeting prostate-specific membrane antigen (“PSMA”). PYLARIFY is a radioactive diagnostic agent indicated for PET imaging of PSMA-positive lesions in men with prostate cancer with suspected metastasis who are candidates for initial definitive therapy and with suspected recurrence based on elevated serum prostate-specific antigen (“PSA”) levels. PYLARIFY is a product in the Company’s radiopharmaceutical oncology product category.The Company commenced its commercial launch of PYLARIFY in the U.S. in June 2021.
Upon commercial launch in June 2021, PYLARIFY was immediately available in select parts of the U.S. Over the course of the remainder of 2021, PYLARIFY availability expanded into additional regions and is now broadly available nationwide. The Company continues to expand its geographic coverage, customer contracting and market access coverage to serve its customers and the U.S. prostate cancer community.
The commercial launch of PYLARIFY is complex and expensive. During 2021, the Company hired additional employees to assist it with the commercialization of PYLARIFY, including in sales, marketing, reimbursement, quality and medical affairs. To manufacture PYLARIFY, the Company assembled and qualified a nationwide network of PMFs with radioisotope-producing cyclotrons that make F 18, which has a 110-minute half-life, so PYLARIFY is manufactured and distributed rapidly to end-users. After being made on a cyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to a radiopharmacist who prepares and dispenses patient-specific doses of the final product. Because each of the PMFs manufacturing these products is deemed by the FDA to be a separate manufacturing site, each has to be approved by the FDA. Although PYLARIFY is now broadly available nationwide, the Company can give no assurance that the FDA will continue to approve PMFs in accordance with the Company’s planned roll-out schedule. If FDA approval of manufacturing sites is delayed or withdrawn, the Company’s future business, results of operations, financial condition and cash flows could be adversely affected.
The Company’s commercial launch also required the Company to obtain adequate coding and coverage for PYLARIFY, including not only coverage from Medicare, Medicaid and other government payors, as well as private payors, but also appropriate payment levels, which adequately cover our customers’ costs of using PYLARIFY in PET/CT imaging procedures. We received notification that our HCPCS code, which enables streamlined billing, went into effect as of January 1, 2022. In addition, effective January 1, 2022, CMS granted Transitional Pass-Through Payment Status in the hospital outpatient setting (“TPT Status”) for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in this setting. TPT Status for PYLARIFY is expected to expire December 31, 2024. After TPT Status expires, under current Medicare rules, PYLARIFY, similar to other diagnostic radiopharmaceuticals, would not be separately reimbursed in the hospital outpatient setting but rather would be included as part of the facility fee a hospital otherwise receives for a PET/CT imaging procedure, and the facility fee does not always cover the cost of a drug used in the procedure. The Company can give no assurance that any CMS reimbursement in the hospital outpatient setting that follows the expiration of TPT Status will be adequate to cover the cost of PYLARIFY used in a PET/CT imaging procedure.
COVID-19 Pandemic
The Company experienced operational and financial impacts from the COVID-19 pandemic beginning late in the first quarter of 2020 and through the date of this filing, including the impact of hospital staffing challenges, vaccination mandates, employee absences due to illness, and a decline in the volume of certain procedures and treatments using the Company’s products. For example, we believe that during the fourth quarter of 2021 sales of DEFINITY were impacted by hospital nursing and sonographer shortages, and sales of AZEDRA were impacted by treatment capacity constraints in hospitals, treatment deferrals and cancellations by patients, and access restrictions by hospitals. There has also been a substantial reduction in pulmonary ventilation studies in which the Company’s product, Xenon, is used. As a result of the COVID-19 pandemic, the Company undertook a thorough analysis of all its discretionary expenses. In the first quarter of 2020, the Company implemented certain cost reduction initiatives. For most of the second quarter of 2020, the Company reduced the Company’s work week from 5 days to 4 days and reduced the pay for employees by varying amounts depending on level of seniority.
86

Table of Contents

During the second quarter of 2020, Progenics also implemented certain cost reduction initiatives and paused new enrollment in the ARROW Phase 2 study of 1095, a PSMA-targeted therapeutic, in metastatic castrate-resistant prostate cancer (“mCRPC”) patients to minimize the risk to subjects and healthcare providers during the pandemic. New enrollment in that study restarted in October 2020. GE Healthcare Limited (“GE Healthcare”), the Company’s development and commercialization partner for flurpiridaz fluorine-18 F 18, also delayed enrollment in the second Phase 3 clinical trial of flurpiridaz F 18 because of the pandemic and resumed enrollment in the third quarter of 2020.
Although some of the restrictions, including stay-at-home mandates, imposed in response to the COVID-19 pandemic have been lifted in much of the United States (the “U.S.”), and there has been a rapid rollout and development of multiple vaccines and boosters, the resurgence of COVID-19 infections continued to impact certain aspects of the Company’s business during 2021 and the pandemic could still have a future negative impact on the Company's business, particularly if there are additional resurgences as a result of mutations or other variations to the virus that increase its communicability or its impact on certain populations, geographic regions and the healthcare system, including elective procedures and hospital access.CVRs.
2. Summary of Significant Accounting Policies
Basis of Presentation and Principles of Consolidation
The accompanying consolidated financial statements have been prepared in accordance with U.S. GAAP. The consolidated financial statements include the accounts of the Company and its direct and indirect wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
86

Table of Contents

Use of Estimates
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. The more significant estimates reflected in the Company’s consolidated financial statements include, but are not limited to, certain judgments regarding revenue recognition, goodwill, tangible and intangible asset valuation, inventory valuation, asset retirement obligations, contingent assets and liabilities, income tax liabilities and related indemnification receivable, deferred tax assets and liabilities and accrued expenses. Actual results could materially differ from those estimates or assumptions.
Revenue Recognition
The Company recognizes revenue when it transfers control of promised goods or services to its customers in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for those goods and services. See Note 3, “Revenue from Contracts with Customers” for further discussion on revenues.
Accounts Receivable, net
Accounts receivable consist of amounts billed and currently due from customers. The Company maintains an allowance for doubtful accounts for estimated losses. In determining the allowance, consideration includes the probability of recoverability based on past experience and general economic factors. Certain accounts receivable may be fully reserved when the Company becomes aware of any specific collection issues. The Company periodically reviews the aging of receivables, payment history and customer creditworthiness to determine if adjustments to the allowance for bad debtdoubtful accounts is necessary. Allowance for bad debtdoubtful accounts has been immaterial for all years presented.
Income Taxes
The Company accounts for income taxes using an asset and liability approach. Income tax (benefit) expense (benefit) represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax attributes are expected to be recovered or paid, and are adjusted for changes in tax rates and tax laws when such changes are enacted.
The Company recognizes deferred tax assets to the extent that the Company believes that these assets are more-likely-than-not to be realized. Valuation allowances are recorded to reduce deferred tax assets when it is more-likely-than-not that the future tax benefit will not be realized. The assessment of whether or not a valuation allowance is required involves weighing both positive and negative evidence, including both historical and prospective information, with greater weight given to evidence that is objectively verifiable. A history of recent losses is negative evidence that is difficult to overcome with positive evidence. In evaluating prospective information there are four sources of taxable income: reversals of taxable temporary differences, items that can be carried back to prior tax years (such as net operating losses), pre-tax income, and prudent and feasible tax planning strategies. Adjustments to the deferred tax valuation allowances are made in the period when those assessments are made.
87

Table of Contents

The Company accounts for uncertain tax positions using a two-step recognition threshold and measurement analysis method to determine the financial statement impact of uncertain tax positions taken or expected to be taken in a tax return. Differences between tax positions taken in a tax return and amounts recognized in the financial statements are recorded as adjustments to other long-term assets and liabilities, or adjustments to deferred taxes, or both. The Company records the related interest and penalties to income tax (benefit) expense.
Net Income (Loss) per Common Share
The Company computes earnings per share using the two-class method. Basic earnings per common share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per common share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period, plus the potential dilutive effect of other securities as if those securities were converted or exercised. The Company’s potentially dilutive shares, which could include shares issuable upon conversion of the 2.625% Convertible Senior Notes due 2027 (the “Notes”), are considered to be common stock equivalents and are only included in the calculation of diluted net income per share when their effect is dilutive. The Company has the option to settle the Notes through cash settlement or a combination of cash and share settlement provided that the principal is settled in cash and the conversion spread is settled in cash or shares as elected by the Company. The Company applies the if-converted method for diluted earnings in order to reflect the conversion spread. During periods in which the Company incurs net losses, both basic and diluted loss per common share is calculated by dividing the net loss by the weighted-average shares of common stock outstanding and potentially dilutive securities are excluded from the calculation because their effect would be antidilutive.

Cash and Cash Equivalents
Cash and cash equivalents include savings deposits, certificates of deposit and money market funds that have original maturities of three months or less when purchased.
Restricted Cash
Restricted cash as of December 31, 20212023 and 2020,2022, represents primarily collateral for a letter of credit securing a lease obligation and a security deposit. The Company believes the carrying value of these assets approximates fair value.
Concentration of Risks and Limited Suppliers
Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of trade accounts receivable. The Company periodically reviews its accounts receivable for collectability and provides for an allowance for doubtful accounts to the extent that amounts are not expected to be collected. The Company sells primarily to clinics, distributors, group practices, hospitals, integrated delivery networksindependent diagnostic testing facilities, and radiopharmacies.
As of December 31, 20212023 and 2020,2022, no customer accounted for greater than 10% of accounts receivable, net. No customer accounted for greater than 10% of revenues for the years ended December 31, 2021, 20202023, 2022 and 2019.2021.
The Company relies on certain materials used in its development and manufacturing processes, some of which are procured from only one or a few sources. The failure of one of these suppliers to deliver on schedule could delay or interrupt the manufacturing or commercialization process and would adversely affect the Company’s operating results. In addition, a disruption in the commercial supply of, or a significant increase in the cost of one of the Company’s materials from these sources could have a material adverse effect on the Company’s business, financial position and results of operations.
The Company currently relies on JHS as its significant manufacturer of DEFINITY and its sole source manufacturer of NEUROLITE, CARDIOLITE and evacuation vials for TechneLite. The Company relies on Samsung Biologics Co., Ltd. (“SBL”) as its sole source manufacturer of DEFINITY RT. The Company has Mo-99 supply agreements with IRE of Belgium, running through December 31, 2022,2024, with auto-renewal provisions and terminable upon notice of non-renewal, and with NTP and its subcontractor ANSTO, running through March 31, 2022, and for which the Company is currently negotiating an extension. The Company also has a Xenon supply agreement with IRE which runs through December 31, 2023, with auto-renewal provisions and terminable upon notice of non-renewal. The Company currently relies on IRE as the sole supplier of bulk-unprocessed Xenon which the Company processes and finishes for its customers. The Company currently relies on JHS as its significant manufacturer of DEFINITY and its sole source manufacturer of NEUROLITE, Cardiolite and evacuation vials for TechneLite.2024.

Table of Contents

The Company assesses the recoverability of inventory to determine whether adjustments for excess and obsolete inventory are required. Inventory that is in excess of future requirements is written down to its estimated net realizable value based on product shelf life, forecasted demand and other factors.
Inventory costs associated with product that has not yet received regulatory approval are capitalized if the Company believes there is probable future commercial use of the product and future economic benefits of the asset. If future commercial use of the product is not probable, then inventory costs associated with such product are expensed as incurred. AsThe Company had no inventory pending regulatory approval as of December 31, 2021 and 2020, the Company had $6.1 million and no capitalized inventories associated with product that did not have regulatory approval, respectively.2023.

Property, plant & equipment are stated at cost. Replacements of major units of property are capitalized, and replaced properties are retired. Replacements of minor components of property and repair and maintenance costs are charged to expense as incurred. Certain costs to obtain or develop computer software are capitalized and amortized over the estimated useful life of the software. Depreciation and amortization isare computed on a straight-line basis over the estimated useful lives of the related assets and recorded throughout

in costs of goods sold and operating expenses in the associated functional expense category which utilizes the associated asset. The estimated useful lives of the major classes of depreciable assets are as follows:

ClassRange of Estimated Useful Lives
Buildings10 - 50 years
Land improvements15 - 40 years
Machinery and equipment3 - 15 years
Furniture and fixtures15 years
Leasehold improvementsLesser of lease term or 15 years
Computer software3 - 5 years

Upon retirement or other disposal of property, plant & equipment, the cost and related amount of accumulated depreciation are removed from the asset and accumulated depreciation accounts, respectively. The difference, if any, between the net asset value and the proceeds is included in operating income.
Included within machinery equipment and fixturesequipment are spare parts. Spare parts include replacement parts relating to plant & equipment and are either recognized as an expense when consumed or reclassified and capitalized as part of the related asset and depreciated over the remaining useful life of the related asset.
Business Combinations
The Company accounts for business combinations using the acquisition method of accounting. The Company recognizes the assets acquired and liabilities assumed in business combinations on the basis of their fair values at the date of acquisition. The Company assesses the fair value of assets acquired, including intangible assets, and liabilities assumed using a variety of methods. Each asset acquired and liability assumed is measured at fair value from the perspective of a market participant. The method used to estimate the fair values of intangible assets incorporates significant assumptions regarding the estimates a market participant would make in order to evaluate an asset, including a market participant’s use of the asset and the appropriate discount rates. Acquired IPR&D is recognized at fair value and initially characterized as an indefinite-lived intangible asset, irrespective of whether the acquired IPR&D has an alternative future use. Any excess purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Transaction costs and restructuring costs associated with a business combination are expensed as incurred.
During the measurement period, which extends no later than one year from the acquisition date, the Company may record certain adjustments to the carrying value of the assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, all adjustments are recorded in the consolidated statements of operations as operating expenses or income. The Company recorded a measurement period adjustment of $2.6 million related to deferred taxes for the three months ended March 31, 2021, which finalized all measurement period adjustments related to the Progenics Acquisition.

Goodwill
Goodwill is not amortized but is instead tested for impairment at least annually and whenever events or circumstances indicate that it is more likely-than-not that theyit may be impaired. The Company has elected to perform the annual test for goodwill impairment as of October 31 of each year.
In performing the Company’s annual assessment, the Company is permitted to first perform a qualitative test and if necessary, perform a quantitative test. If the Company is required to perform the quantitative impairment test of goodwill, the Company compares the fair value of a reporting unit to its carrying value. If the reporting unit’s carrying value exceeds its fair value, the Company would record an impairment loss to the extent that the carrying value of goodwill exceeds its implied fair value. The Company estimates the fair value of its reporting units using discounted cash flow or other valuation models, such as comparative transactions and market multiples. The Company performed a qualitative assessment and did not recognize any goodwill impairment charges during the years ended December 31, 2021, 20202023, 2022 or 2019.2021.
Intangible and Long-Lived Assets
89

Table of Contents

The Company tests intangible and long-lived assets for recoverability whenever events or changes in circumstances suggest that the carrying value of an asset or group of assets may not be recoverable. The Company measures the recoverability of assets to be held and used by comparing the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset. If those assets are considered to be impaired, the impairment equals the amount by which the carrying amount of the assets exceeds the fair value of the assets. Any impairments are recorded as permanent reductions in the carrying amount of the assets. See Note 7, “Property, Plant and Equipment, Net” for further details on impairment. Long-lived assets, other than goodwill and other intangible assets that are held for sale are recorded at the lower of the carrying value or the fair market value less the estimated cost to sell.
Intangible assets, consisting of patents, trademarks, customer relationships, a currently marketed product, licenses and developed technology related to the Company’s products are amortized in a method equivalent to the estimated utilization of the economic benefit of the asset.
Costs of IPR&D intangible assets acquired as part of an asset acquisition that have no alternative future use are expensed when incurred. Milestone payments made after regulatory approval are capitalized as an intangible asset and amortized over an estimated useful life of the product. Cash payments related to acquired IPR&D intangible assets are reflected as an investing cash flow in the Company's consolidated statement of cash flows.
The Company’s in-process research and development (“IPR&D”) represents&D intangible assets includes intangible assets acquired in a business combination that are used in research and development activities but have not yet reached technological feasibility, regardless of whether they have alternative future use. The primary basis for determining the technological feasibility or completion of these projects is obtaining regulatory approval to market the underlying products in an applicable geographic region. Because obtaining regulatory approval can include significant risks and uncertainties, the eventual realized value of the acquired IPR&D projects may vary from their fair value at the date of acquisition. The Company classifies IPR&D intangible assets acquired in a business combination as an indefinite-lived intangible asset until the completion or abandonment of the associated research and development efforts. Upon completion of the associated research and development efforts, the Company will determine the useful life and begin amortizing the assets to reflect their use over their remaining lives. Upon permanent abandonment, the Company writes-off the remaining carrying amount of the associated IPR&D intangible asset. IPR&D intangible assets are tested at least annually as of October 31 or when a triggering event occurs that could indicate a potential impairment and any impairment loss is recognized in the Company’s consolidated statements of operations. See Note 11,10, “Intangibles, net and Goodwill” for further details on impairment.
Contingencies
In the normal course of business, the Company is subject to loss contingencies, such as legal proceedings and claims arising out of its business, that cover a wide range of matters, including, among others, product and environmental liability. The Company records accruals for those loss contingencies when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Company does not recognize gain contingencies until realized.
Convertible Notes
The Company evaluates convertible notes to determine if those contracts or embedded components of those contracts qualify as derivatives to be separately accounted for. The change in fair value of any separately recognized derivative is recorded in the consolidated statement of operations as other income or expense. Upon conversion, exercise or cancellation of a derivative instrument, the instrument is marked to fair value at the date of conversion, exercise or cancellation.
Fair Values of Financial Instruments
The estimated fair values of the Company’s financial instruments, including its cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate the carrying values of these instruments due to their short term nature. The estimatedCompany’s long-term debt has triggering events that would impact the fair value of the instruments. The Company determined that no triggering event has occurred during the years ended December 31, 2023 and December 31, 2022. As of December 31, 2023, the fair value of the Company’s long termconvertible debt approximates itswas estimated to be approximately $644.3 million based on external pricing data, including quoted market prices of these instruments and was classified as a Level 1 measurement within the fair value hierarchy. As of December 31, 2022, the carrying values as the applicable interest rates are subject to change with market interest rates.

Contingent Consideration Liabilities
The estimated fair value of contingent consideration liabilities are initially measured and recorded on the acquisition date, are considered to be a Level 3 instrument and are reviewed quarterly, or whenever events or circumstances occur that indicate a change in

Table of Contents

fair value. The contingent consideration liabilities are recorded at fair value at the end of each reporting period with changes in estimated fair values recorded in general and administrative expenses in the consolidated statements of operations.
90

Table of Contents

The estimated fair value is determined based on probability adjusted discounted cash flows and Monte Carlo simulation models that include significant estimates and assumptions pertaining to commercialization events and sales targets. The most significant unobservable inputs are the probabilities of achieving regulatory approval of the development projects and subsequent commercial success.
Significant changes in any of the probabilities of success would result in a significantly higher or lower fair value measurement. Significant changes in the probabilities as to the periods in which milestones will be achieved would result in a significantly lower or higher fair value measurement.
The Company's acquisitions accounted for as asset acquisitions may also include contingent consideration payments to be made for sales-based milestones, development and regulatory milestones. The Company assesses whether such contingent consideration meets the definition of a derivative. Contingent consideration payments in an asset acquisition not required to be accounted for as derivatives are recognized when the contingency is resolved, and the consideration is paid or becomes payable. Contingent consideration payments required to be accounted for as derivatives are recorded at fair value on the date of the acquisition and are subsequently remeasured to fair value at each reporting date. Upon recognition of the contingent consideration payment, the amount is included in the cost of the acquired asset or group of assets.
Derivative Instruments
The Company useshas used interest rate swaps to reduce the variability in cash flows associated with a portion of the Company’s forecasted interest payments on its variable rate debt. To qualify for hedge accounting, the hedging instrument must be highly effective at reducing the risk from the exposure being hedged. Further, the Company must formally document the hedging relationship at inception and, on at least a quarterly basis, continually reevaluate the relationship to ensure it remains highly effective throughout the life of the hedge. The Company does not enter into derivative financial instruments for speculative or trading purposes.
Advertising and Promotion Costs
Advertising and promotion costs are expensed as incurred. During the years ended December 31, 2021, 20202023, 2022 and 2019,2021, the Company incurred $17.5$26.0 million, $5.2$26.0 million and $3.8$17.5 million, respectively in advertising and promotion costs, which are included in sales and marketing in the consolidated statements of operations.
Research and Development
Research and development costs are expensed as incurred and relate primarily to the development of new products to add to the Company’s portfolio and costs related to its medical affairs and medical information functions. Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are deferred and recognized as an expense as the goods are delivered or the related services are performed.
Foreign Currency
The consolidated statements of operations of the Company’s foreign subsidiaries are translated into U.S. Dollars using weighted-average exchange rates. The net assets of the Company’s foreign subsidiaries are translated into U.S. Dollars using the end of period exchange rates. The impact from translating the net assets of these subsidiaries at changing rates are recorded in the foreign currency translation adjustment account, which is included in accumulated other comprehensive loss in the consolidated balance sheets.
Remeasurement of the Company’s foreign currency denominated transactions are included in net income. Transaction gains and losses are reported as a component of other loss (income) loss in the consolidated statements of operations.
Stock-Based Compensation
The Company’s stock-based compensation cost is measured at the grant date of the stock-based award based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited. The Company estimates the fair value of each stock-based award on its measurement date using either the current market price of the stock, the Black-Scholes option valuation model or the Monte Carlo simulation valuation model, whichever is most appropriate. The Black-Scholes and Monte Carlo simulation valuation models incorporate assumptions such as stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield.
Expected volatility is based on the historical volatility of the Company’s stock price. The risk-free interest rates are based on quoted U.S. Treasury rates for securities with maturities approximating the awards’ expected lives. Expected lives are principally based on the Company’s historical exercise experience with previously issued awards. The expected dividend yield is zero as the Company has never paid dividends and does not currently anticipate paying any in the foreseeable future.

Table of Contents

Expense for performance restricted stock awards is recognized based upon the fair value of the awards on the date of grant and the number of shares expected to vest based on the terms of the underlying award agreement and the requisite service period(s).

Comprehensive Income (Loss) Income
Comprehensive income (loss) income consists of net income (loss) income and other gains and losses affecting stockholders’ equity that, under U.S. GAAP, are excluded from net income. For the Company, other comprehensive income (loss) income consists of foreign currency translation gains and losses as well as realized and unrealized gains and losses on cash flow hedges related to the Company’s interest rate swaps. The accumulated other comprehensive lossincome (loss) balance consists entirely of foreign currency translation gains and losses and realized and unrealized gains and losses on outstanding cash flow hedges related to the Company’s interest rate swaps.
Asset Retirement Obligations
The Company’s compliance with federal, state, local and foreign environmental laws and regulations may require it to remove or mitigate the effects of the disposal or release of chemical substances in jurisdictions where it does business or maintains properties. The Company establishes accruals when those costs are legally obligated and can be reasonably estimated. Accrual amounts are estimated, which may include the assistance of third partythird-party environmental specialists, and are based on currently available information, regulatory requirements, remediation strategies, historical experience, the relative shares of the total remediation costs, a relevant discount rate, and the time periods of when estimated costs can be reasonably predicted. Changes in these assumptions could impact the Company’s future reported results.
The Company has production facilities which manufacture and process radioactive materials at its North Billerica, Massachusetts campus and its Somerset, New Jersey site. The Company considers its legal obligation to remediate its facilities upon a decommissioning of its radioactive-related operations as an asset retirement obligation. The fair value of a liability for asset retirement obligations is recognized in the period in which the liability is incurred. The liability is measured at the present value of the obligation expected to be incurred and is adjusted in subsequent periods as accretion expense is recorded. The corresponding asset retirement costs are capitalized as part of the carrying values of the related long-lived assets and depreciated over the assets’ useful lives.
The Company has identified conditional asset retirement obligations related to the future removal and disposal of asbestos contained in certain of the buildings located on the Company’s North Billerica, Massachusetts campus. The Company believes the asbestos is appropriately contained and it is compliant with all applicable environmental regulations. If these properties undergo major renovations or are demolished, certain environmental regulations are in place, which specify the manner in which asbestos must be handled and disposed. The Company is required to record the fair value of these conditional liabilities if they can be reasonably estimated. As of December 31, 20212023 and 2020,2022, sufficient information was not available to estimate a liability for such conditional asset retirement obligations as the obligations to remove the asbestos from these properties have indeterminable settlement dates. As such, no liability for conditional asset retirement obligations has been recorded in the accompanying consolidated balance sheets as of December 31, 20212023 and 2020.2022.

Self-Insurance Reserves
The Company’s consolidated balance sheets at December 31, 20212023 and 20202022 include $0.7$1.0 million and $0.6$0.9 million of accrued liabilities associated with employee medical costs that are retained by the Company, respectively. The Company estimates the required liability of those claims on an undiscounted basis based upon various assumptions which include, but are not limited to, the Company’s historical loss experience and projected loss development factors. The required liability is also subject to adjustment in the future based upon changes in claims experience, including changes in the number of incidents (frequency) and change in the ultimate cost per incident (severity).

ASU 2020-06, “Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40)”This ASU provides guidance to simplify the complexity associated with accounting for convertible instruments and derivatives. For convertible instruments, the number of major separation models required were reduced. Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. This ASU further amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. The ASU simplifies the diluted net income per share calculation in certain areas as well.January 1, 2021The adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

In December 2023, the FASB issued ASU 2023-07,
Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires all public entities, including public entities with a single reportable segment, to provide in interim and annual periods one or more measures of segment profit or loss used by the chief operating decision maker to allocate resources and assess performance. Additionally, the standard requires disclosures of significant segment expenses and other segment items as well as incremental qualitative disclosures. The guidance in this update is effective for fiscal years beginning after December 15, 2023, and interim periods after December 15, 2024. The Company is currently in the process of evaluating the effects of this pronouncement on our related disclosures.
In December 2023, the FASB also issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires enhanced income tax disclosures, including specific categories and disaggregation of information in the effective tax rate reconciliation, disaggregated information related to income taxes paid, income or loss from continuing operations before income tax expense or benefit, and income tax expense or benefit from continuing operations. The requirements of the ASU are effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently in the process of evaluating the impact of this pronouncement on our related disclosures.

3. Revenue from Contracts with Customers
Revenue Recognition
Revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these goods or services. To achieve this core principle, the Company applies the following five steps: (1) identify the contracts with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the Company satisfies a performance obligation.
Disaggregation of Revenue

This category represents the delivery of physical goods. The Company applies the same revenue recognition policies and judgments for all of its principal products.
(2)The Company recognized $24.0 million license revenue in the first quarter of 2022 related to an agreement with Novartis Pharma AG.
The Company classifies its revenues into three product categories: precision diagnostics, radiopharmaceutical oncology,Radiopharmaceutical Oncology, Precision Diagnostics, and strategic partnershipsStrategic Partnerships and other revenue.Other Revenue. Radiopharmaceutical Oncology includes PYLARIFY and AZEDRA. In 2023, the Company announced its decision to discontinue the production and promotion of AZEDRA and it does not expect AZEDRA to contribute to the business after the first quarter of 2024. Precision diagnosticsDiagnostics includes DEFINITY, TechneLite and other diagnostic imaging diagnostic products. Radiopharmaceutical oncology consists primarily of PYLARIFYStrategic Partnerships and AZEDRA. Strategic partnerships and other revenueOther Revenue includes strategic partnerships and other arrangements related to other products of the Company, including our royalty revenue from our license of RELISTOR. On August 2, 2023, the Company sold the RELISTOR royalty asset under its license agreement with Bausch; the Company retained the rights to future sales-based milestone payments. During the fourth quarter of 2023, the Company earned a $15.0 million sales-based milestone payment.
On January 31, 2022, the Company entered into a global settlement agreement with Novartis Pharma AG (“Novartis”), Advanced Accelerator Applications USA, Inc., Endocyte, Inc. and their affiliates (the “Novartis Agreement”) to settle certain disputes between the parties. Under the Novartis Agreement, Novartis agreed to make a lump sum payment to the Company, as well as to reimburse the Company for certain fees and expenses in connection with certain German litigation, and the Company agreed to license certain intellectual property to Novartis. In addition, the Company agreed to supply PYLARIFY for clinical purposes at an arms-length value which will be recorded revenue in the future as product is provided. In accordance with the Company's ASC 606, Revenue from Contracts with Customers, assessment, Novartis is considered to be a customer. The Company determined that the $24.0 million constituted a single element which was satisfied on the date of the execution of the Novartis Agreement. The Company determined that the license of intellectual property carried a fair value of $24.0 million. As such, the Company assigned the value to the fair value of the license, which constitutes the entire transaction price and does not require further allocation. The Company determined that the $24.0 million represented the point at which the licensee was able to use and benefit from the license and recognized revenue when the license was granted to Novartis upon execution of the Novartis Agreement. The Company recognized the $24.0 million fee as revenue on its consolidated statement of operations for the quarter ended March 31, 2022. The Company received the $24.0 million payment in April 2022.

Product Revenue, Net
The Company sells its products principally to clinics, distributors, group practices, hospitals, integrated delivery networksindependent diagnostic testing facilities, and radiopharmacies. The Company considers customer purchase orders, which in some cases are governed by master sales or group purchasing organization agreements, to be the contracts with a customer.
For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled.
94

Table of Contents

The Company typically invoices customers upon satisfaction of identified performance obligations. As the Company’s standard payment terms are 30 to 60 days from invoicing, the Company has elected to use the significant financing component practical expedient.
The Company allocates the transaction price to each distinct product based on their relative standalone selling price. The product price as specified on the purchase order is considered the standalone selling price as it is an observable input which depicts the price as if sold to a similar customer in similar circumstances.
Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which typically occurs upon delivery to the customer. Further, in determining whether control has transferred, the Company considers if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer.
Frequently, the Company receives orders for products to be delivered over multiple dates that may extend across several reporting periods. The Company invoices for each delivery upon shipment and recognizes revenues for each distinct product delivered, assuming transfer of control has occurred.
The Company generally does not separately charge customers for shipping and handling costs, but any shipping and handling costs charged to customers are included in product revenue, net. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.
Variable Consideration
Revenues from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established for discounts, returns, rebates and allowances that are offered within contracts between the Company and its customers. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as a current liability. Where appropriate, these estimates take into consideration a range of possible outcomes which are probability-weighted for relevant factors such as the Company’s historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract. The amount of variable consideration which is included in the transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the
95

Table of Contents

Company’s estimates. If actual results in the future vary from the Company’s estimates, the Company adjusts these estimates, which would affect product revenue and earnings in the period such variances become known.
Rebates and Allowances: The Company provides certain customers with rebates and allowances that are explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product revenue is recognized. The Company establishes a liability for such amounts, which is included in accrued expenses in the accompanying consolidated balance sheets. These rebates and allowances result from performance-based offers that are primarily based on attaining contractually specified sales volumes and administrative fees the Company is required to pay to group purchasing organizations. The Company estimates the amount of rebates and allowances that are explicitly stated in the Company’s contracts based on a combination of actual purchases and an estimate of the customer’s buying patterns.
Product Returns: The Company generally offers customers a limited right of return due to non-conforming product. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company currently estimates product return liabilities using its historical product return information and considers other factors that it believes could significantly impact its expected returns, including product recalls. Reserves for product returns are not significant to the Company due to the nature of its products including radiopharmaceutical products with limited half-lives.

License and Royalty Revenues
The Company has entered into licensing agreements, under which it licenses certain rights to third parties. The terms of these arrangements typically include payment to the Company of one or more of the following: non-refundable, up-front license fees; development, regulatory and commercial milestone payments; and royalties on net sales of licensed products. The Company also has distribution licenses which are treated as combined performance obligations with the delivery of its products and are classified as product revenue, net.
In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its agreements, the Company performs the five-step approach stated earlier. The Company uses judgment in determining the number of performance obligations in a license agreement by assessing whether the license is distinct or should be combined with another performance obligation, as well as the nature of the license. As part of the accounting for these arrangements, the Company must develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract. The Company uses key assumptions to determine the stand-alone selling price, which may include market conditions, reimbursement rates for personnel costs, development timelines and probabilities of regulatory success.
Licenses of intellectual property: If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from non-refundable, up-front fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone Payments: At the inception of each arrangement that includes development or sales milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are outside the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect license and royalty revenues and earnings in the period of adjustment. At December 31, 2021,2023, the Company is constraining variable consideration related to developmentfor the milestone payments requiring regulatory approvalsis constrained and salesis excluded from contract price until the milestone payments related to achievement of certain sales targets.is achieved by the customer.
Royalty Revenues: For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Contract Costs
The Company recognizes an asset for incremental costs of obtaining a contract with a customer if it expects to recover those costs. The Company’s sales incentive compensation plans qualify for capitalization since these plans are directly related to sales achieved during a period of time. However, the Company has elected the practical expedient to expense the costs as they are incurred, within sales and marketing expenses, since the amortization period is less than one year.
The Company recognized certain revenues as follows:

The Company did not record any revenue related to performance obligations satisfied (or partially satisfied) in previous periods during the years ended December 31, 20212023 and 2020.2022.
The Company’s performance obligations are typically part of contracts that have an original expected duration of one year or less. As such, the Company is not disclosing the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied (or partially satisfied) as of the end of the reporting period.

4. Fair Value of Financial Instruments
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability of fair value measurements, financial instruments are categorized based on a hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:
Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2 — Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.) and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).
Level 3 — Unobservable inputs that reflect a Company’s estimates about the assumptions that market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available, including its own data.
The Company’s financial assets and liabilities measured at fair value on a recurring basis consist of money market funds, interest rate swaps, a contingent receivable and contingent consideration liabilities. The Company invests excess cash from its operating cash accounts in overnight investments and reflects these amounts in cash and cash equivalents in the consolidated balance sheets at fair value using quoted prices in active markets for identical assets. The fair value of the interest rate swaps is determined based on observable market-based inputs, including interest rate curves and reflects the contractual terms of these instruments, including the period to maturity. Please refer to Note 14,13, “Derivative Instruments”, for further details on the interest rate swaps. The Company recorded a contingent receivable and the contingent consideration liabilities resulting from the Progenics Acquisition at fair value based on inputs that are not observable in the market. Please refer to Note 8, “Business Combinations”, for further details on the acquisition.

As part of the Progenics Acquisition, the Company acquired the right to receive certain future milestone and royalty payments due to Progenics from CytoDyn Inc. (“CytoDyn”) related to a prior sale of certain intellectual property. The Company has the right to receive $5.0 million upon regulatory approval and a 5% royalty on net sales of approved products. The Company considers the contingent receivable a Level 3 instrument (one with significant unobservable inputs) in the fair value hierarchy. The estimated fair value was determined based on probability adjusted discounted cash flows that included significant estimates and assumptions

pertaining to regulatory events and sales targets. During the fourth quarter of 2022, the Company reduced the probability to zero as CytoDyn withdrew their regulatory application. The most significant unobservable inputs are the probabilities of achieving regulatory approval of the development projects and subsequent commercial success.
As part of the Progenics Acquisition, the Company issued CVRs and recorded the fair value as part of consideration transferred. Each CVR will entitleentitled its holder to receive a pro rata share of aggregate cash payments equal to 40% of U.S. net sales generated by PYLARIFY in 2022 and 2023 in excess of $100.0 million and $150.0 million, respectively.respectively, subject to a maximum cap. Refer to Note 1, “Description“Basis of Business”Presentation” for further details on the CVRs. Additionally,The Company paid out the maximum amount payable under the CVRs from available cash in May 2023 in full satisfaction of the CVR obligation.
The Company also assumed contingent consideration liabilities related to a previous acquisition completed by Progenics in 2013 (“2013 Acquisition”). These contingent consideration liabilities include potential payments of up to $70.0 million if the Company attains certain net sales targets primarily for AZEDRA and 1095 (also known as 131 I-MIP-1095) and a $5.0 million 1095 commercialization milestone. Additionally, there is a potential payment of up to $10.0 million related to a 1404 commercialization milestone. The Company’s total potential payments related to the 2013 Acquisition are approximately $85.0 million. The Company considers the contingent consideration liabilities relating to the CVRs and the 2013 Acquisition each a Level 3 instrument (one with significant unobservable inputs) in the fair value hierarchy. The estimated fair value of these was determined based on probability adjusted discounted cash flows and Monte Carlo simulation models that included significant estimates and assumptions pertaining to commercialization events and sales targets. The most significant unobservable inputs with respect to 1095 and 1404 are the probabilities of achieving regulatory approval of thethose development projects and subsequent commercial success.
Significant changes in any of the probabilities of success, the probabilities as to the periods in which sales targets and milestones will be achieved, discount rates or underlying revenue forecasts would result in a significantly higher or lower fair value measurement. The Company records the contingent consideration liability at fair value with changes in estimated fair values recorded in general and administrative expenses in the consolidated statements of operations. The Company can give no assurance that the actual amounts paid, if any, in connection with the contingent consideration liabilities including the CVRs, will be consistent with any recurring fair value estimate of such contingent consideration liabilities.
The following tables summarize quantitative information and assumptions pertaining to the fair value measurement of assets and liabilities using Level 3 inputs as of December 31, 2021.2023.

On June 19, 2020,The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. Under the Company completedAct, research and experimental expenditures incurred for tax years beginning after December 31, 2021, must be capitalized and amortized ratably over five or fifteen years for tax purposes, depending on where the Progenics Acquisitionresearch activities are conducted. If the requirement to capitalize Section 174 expenditures is not modified, it may impact our cash tax liability in a transaction thatfuture years. The increase in worldwide net deferred tax assets is expectedprimarily due to qualify as a tax-deferred reorganization under Section 368the tax capitalization of the Internal Revenue Code. The transaction resultedCompany’s current year research and development expenses that are not currently deductible in an ownership change of Progenics under Section 382 of2023 and the Internal Revenue Code,decrease in deferred tax liabilities related to the AZEDRA and a limitation on theRELISTOR royalty intangible assets, partially offset by utilization of Progenics’ precombination tax attributes. All of Progenics’ precombination research credits and Orphan drug credits have been removed from the balance sheet, and the gross carrying value of the tax loss carryforwards reduced to their realizable value on the opening balance sheet, in accordance with the Section 382 limitation. Deferred tax liabilities of $92.3 million on acquired identified intangibles were recorded at acquisition resulting in a small net overall deferred tax liability for Progenics after the application of acquisition accounting. The Company also acquired estimated utilizable U.S. federal loss carryforwards of $338.7 million, tax-effected state loss carryforwards of $12.5 million and state tax credits of $2.5 million as a result of the Progenics acquisition. The utilization of these losses and credits is subject to annual limitations based on Sections 382 and 383 of the Internal Revenue Code.operating losses.
The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realizability of deferred tax assets requires significant management judgment. In determining whether its deferred tax assets are more-likely-than-not realizable, the Company evaluated all available positive and negative evidence,evidence. As of December 31, 2023 and weighed2022, the objective evidenceCompany maintains a valuation allowance of $3.6 million and expected impact. The Company continues$3.5 million, respectively, primarily related to record valuation allowances of $1.2 million against the net deferred tax assets of its U.K. subsidiary, $1.9 million against the net deferred tax assetscertain of its Sweden subsidiary,foreign subsidiaries.
Utilization of net operating loss carryforwards and research and development credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that could occur in the future in accordance with Section 382 of the Internal Revenue Code of 1986 (“IRC Section 382”) and with Section 383 of the Internal Revenue Code of 1986, as well as similar state provisions. These ownership changes may limit the amount of net operating loss carryforwards and research and development credit carryforwards that can be utilized annually to offset future taxable income and taxes, respectively. In general, an ownership change, as defined by IRC Section 382, results from transactions which impact the ownership of certain stockholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period.
At December 31, 2023, the Company had U.S. federal net operating loss carryforwards of approximately $297.6 million, $157.9 million of which will expire between 2027 and 2037, and $139.6 million of which can be carried forward indefinitely. The Company’s state net operating losses are $12.5 million on a tax-effected basis, which will expire between 2024 and 2040. The Company has state research credit carryforwards of $2.1 million, which will expire between 2026 and 2038. The Company has state investment tax credit carryforwards of $0.8 million against certain domestic state tax credits and state loss carryforwards.
The Company will continue to assess the level of the valuation allowance required. If the weight of negative evidence exists in future periods to again support the recording of a partial or full valuation allowance against the Company’s deferred tax assets, there would likely be a material negative impact on the Company’s results of operations in that future period.
A summary of the changes in the Company’s valuation allowance is summarized below:which have no expiration date.

In connection with the Company’s acquisition of the medical imaging business from Bristol-Myers Squibb (“BMS”) in 2008, the Company recorded a liability for uncertain tax positions related to the acquired business and simultaneously entered into a taxan indemnification agreement with BMS under which BMS agreed to indemnify the Company for any payments made to settle those uncertain tax positions with the taxing authorities. A long-term receivable is recorded within other long-term assets to account for the expected value to the Company of future indemnification payments, net of actual tax benefits received, to be paid on behalf of the Company by BMS.
In accordance with the Company’s accounting policy, the change in the tax liability, penalties and interest associated with these obligations (net of any offsetting federal or state benefit) is recognized within income tax expense. As these reserves change, adjustments are included in income tax expense while the offsetting adjustment is included in other income. Assuming that the receivable from BMS continues to be considered recoverable by the Company, there will be no effect on net income and no net cash outflows related to these liabilities. Included in other (income) loss for the years ended December 31, 2023, 2022 and 2021, is tax indemnification expense (income), net of $4.9 million, $9.6 million and $7.1 million, respectively.

During the three months ended March 31, 2020,June 30, 2023, as a result of a decline in expected future cash flows and the effect of the COVID-19 pandemic related to a certain other nuclear legacy manufacturing assets,asset group, the Company determined certain impairment triggers had occurred. Accordingly, theThe Company performed anreviewed revised undiscounted cash flow analysisflows that were estimated to be generated by the asset group as of March 31, 2020.June 30, 2023. Based on the undiscounted cash flow analysis, the Company determined that the manufacturing assetsasset group had net carrying values that exceeded their estimated undiscounted future cash flows. The Company then estimated the fair valuesvalue of the asset group based on their discounted cash flows. The carrying value exceeded the fair value and as a result, the Company recorded a non-cashnoncash impairment of $7.3$6.0 million for the yearsix months ended December 31, 2020June 30, 2023 in cost of goods sold in the consolidated statementstatements of operations.
In connectionLong-Lived Assets Held for Sale
During the first quarter of 2023, the Company committed to a plan to sell a portion of its land and buildings associated with its Billerica, Massachusetts campus. Effective March 16, 2023, the Company entered into a purchase and sale agreement (the “P&S”) with a contract termination in the fourth quarterprospective buyer. The assets were classified as held for sale and comprised entirely of 2020, theproperty, plant and equipment, net. The Company transferred ownership of certain manufacturing assets and recorded a non-cash loss on disposal of assets of $1.8 million as well as paid $0.5 million, all of which is recorded in cost of goods sold in the consolidated statement of operations.

8. Business Combinations
On June 19, 2020, the Company completed the Progenics Acquisition. The acquisition combined the commercialization, supply chain and manufacturing expertise of the Company with the currently commercialized products and research and development pipeline of Progenics. Progenics brought to the Company several commercial products and a pipeline of product candidatesdetermined that further diversify the Company’s commercial and clinical development portfolios.
Under the terms of the Merger Agreement, the Company acquired all the issued and outstanding shares of Progenics common stock for a purchase price of $419.0 million by means of an all-stock transaction, which includes options to purchase Holdings common stock (“Replacement Stock Options”) for precombination services as well as CVRs.
The CVRs were accounted for as contingent consideration, the fair value of which was determined using a Monte Carlo simulation. Additionally, the fair value of the Replacement Stock Options was recordednet assets being sold exceeded the carrying value as a component of consideration transferred. Finally, as a result ofSeptember 30, 2023. The purchase price for the Progenics Acquisition, Lantheus effectively settled an existing bridge loan with Progenics at the recorded amount (principal and accrued interest) of $10.1campus sale is $10.0 million representing the effective settlement of a preexisting relationship. This effective settlement of the bridge loan was treated as a component of consideration transferred.in cash.

The transaction was accounted for as a business combination which requires that assets acquired and liabilities assumed be recognized at their fair value as of the acquisition date. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to value the assets acquired and liabilities assumed on the acquisition date, its estimates and assumptions are subject to refinement. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results of operations. The Company recorded a measurement period adjustment of $2.6 million related to deferred taxes for the three months ended March 31, 2021, which finalized all measurement period adjustments related to the Progenics Acquisition.
The following table summarizes the provisional amounts recognized for assets acquired and liabilities assumed as of the acquisition date, as well as measurement period adjustments made to the amounts initially recorded in June 2020. The measurement period adjustments primarily resulted from finalizing the fair values of certain intangible assets and liabilities, deferred taxes and other changes to certain tangible assets and liability accounts. Measurement period adjustments were recognized in the reporting period in which the adjustments were determined and calculated as if the accounting had been completed at the acquisition date. The related impact to net loss that would have been recognized in previous periods if the adjustments were recognized as of the acquisition date is immaterial to the consolidated financial statements.

Intangible assets acquired consist of currently marketed products, licenses, developed technology and in-process research and development (“IPR&D”). The fair value of the acquired intangible assets was determined based on estimated future revenues, royalty rates and discount rates, among other variables and estimates. The acquired intangible assets subject to amortization were assigned useful lives based on the expected use of the assets and the regulatory and economic environment within which they are being used and are being amortized on a straight-line basis over the respective estimated useful lives. The estimated fair values of the IPR&D assets were determined based on the present values of the expected cash flows to be generated by the respective underlying assets. The Company used a discount rate of 23.0% and cash flows that have been probability adjusted to reflect the risks of product commercialization, which the Company believes are appropriate and representative of market participant assumptions.
As part of the Progenics Acquisition, the Company acquired the right to receive certain future milestone and royalty payments due to Progenics, related to a prior sale of certain intellectual property. The estimated fair value of the acquired contingent receivable of $10.1 million was determined by applying a probability adjusted discounted cash flow model based on estimated future expected payments and recorded in other long-term assets.
The goodwill recognized is attributable to future technologies that are not separately identifiable that could potentially add to the currently developed and pipeline products and Progenics’ assembled workforce. Future technologies did not meet the criteria for recognition separately from goodwill because they are part of the future development and growth of the business. Goodwill of $45.5 million recognized in connection with the acquisition is not deductible for tax purposes.
The Company recognized $11.9 million of acquisition-related costs, including legal, accounting, compensation arrangements and other related fees that were expensed when incurred in the year ended December 31, 2020, respectively. These costs are recorded in general and administrative expenses in the consolidated statements of operations.
Progenics Pro Forma Financial Information
Progenics has been included in the Company’s consolidated financial statements since the acquisition date. Progenics contributed revenues of $12.4 million, as well as a net loss of $27.1 million to the Company’s consolidated statement of operations for the year ended December 31, 2020.

9.8. Sale of Puerto Rico Subsidiary
During the fourth quarter of 2020, the Company entered into a stock purchase agreement (the “SPA”) with one of its existing radiopharmacy customers to sell all the stock of its Puerto Rico radiopharmacy subsidiary. The assets were classified as held for sale and the Company determined that the fair value of the net assets being sold significantly exceeded the carrying value as of December 31, 2020.

2020 AmendmentConvertible Notes
On June 19, 2020,December 8, 2022, the Company amended its 2019 Credit Agreementissued $575.0 million in aggregate principal amount of 2.625% Convertible Senior Notes due 2027 (the “Amendment”“Notes”) as a result, which includes $75.0 million in aggregate principal amount of Notes sold pursuant to the full exercise of the impactinitial purchasers’ option to purchase additional Notes. The Notes were issued under an indenture, dated as of December 8, 2022 (the “Indenture”), among the Company, LMI (the “Guarantor”), a wholly owned subsidiary of the COVID-19 pandemicCompany, as Guarantor, and U.S. Bank Trust Company, National Association, as Trustee. The net proceeds from the issuance of the Notes were approximately $557.8 million after deducting the initial purchasers’ discounts and offering expenses payable by the Company.
The Notes are senior unsecured obligations of the Company. The Notes are fully and unconditionally guaranteed on a senior unsecured basis by the Guarantor. The Notes bear interest at a rate of 2.625% per year, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2023, and will mature on December 15, 2027 unless earlier redeemed, repurchased or converted in accordance with their terms. The initial conversion rate for the Notes is 12.5291 shares of the Company’s common stock per $1,000 in principal amount of Notes (which is equivalent to an initial conversion price of approximately $79.81 per share of the Company’s common stock, representing an initial conversion premium of approximately 42.5% above the closing price of $56.01 per share of the Company’s common stock on December 5, 2022). In no event shall the conversation rate per $1,000 in principal amount of notes exceed 17.8539 shares of the Company’s common stock. Prior to the close of business on the business and operationsday immediately preceding September 15, 2027, the Notes may be converted at the option of the holders only upon occurrence of specified events and during certain periods, and thereafter until the close of business on the business day immediately preceding the maturity date, the Notes may be converted at any time. The Company will satisfy any conversion by paying cash up to the aggregate principal amount of the Notes to be converted and by paying or delivering, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock, at its election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the Notes being converted. The Company may redeem for cash all or any portion of the Notes, at its option, on or after December 22, 2025 if the closing sale price per share of the Company’s common stock exceeds 130% of the conversion price of the Notes for a specified period of time. The redemption price will be equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.
The Company evaluated the Notes upon completion of the sale and concluded on the following features:
Conversion Feature: The Company determined that the conversion feature qualifies for the classification of equity. As a result, the conversion feature should not be bifurcated as a derivative instrument and the near-term higher levelNotes were accounted for as a single liability.
Redemption Features: The redemption features were reviewed within the Notes and the Company determined that the redemption features are closely related to the Notes and as such should not be separately accounted for as a bifurcated derivative instrument.
Additional Interest Features: The Notes may result in additional interest if the Company fails to timely file any document or report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of indebtedness resultingthe Securities Exchange Act of 1934. The Company will pay additional interest on the notes at a rate equal to 0.25% to 0.50% per annum based on the principal amount of notes outstanding for each day the Company failure to file has occurred or the notes are not otherwise freely tradable. Further, if the notes are assigned a restricted CUSIP number or the notes are not otherwise freely tradable pursuant to Rule 144 under the Securities Act by holders other than our affiliates or holders that were our affiliates at any time during the three months immediately preceding as of the 385th day after the last date of original issuance of the notes offered hereby, the Company will pay additional interest on the notes at a rate equal to (i) 0.25% to 0.50% per annum based on the principal amount of notes outstanding for each day until the restrictive legend has been removed from the Company’s decision not to immediately repaynotes, the Progenics debt secured bynotes are assigned an unrestricted CUSIP and the RELISTOR royalties following the Progenics Acquisition.notes are freely tradable. The Company accountedconcluded that the interest feature is unrelated to the credit risk and should be bifurcated from the Notes, however, the Company assessed the probabilities of triggering events occurring under these features and does not expect to trigger the aforementioned events. These events will continue to be monitored to determine whether the interest feature will be bifurcated if it has value.
As of December 31, 2023, the carrying value of the Notes was $575.0 million, had an unamortized discount of zero, and the fair value of the liability was $575.0 million. The Company recorded interest expense of approximately $15.1 million related to the Notes for the Amendment as a debt modification and capitalized $1.2 million of associated costs.
The Amendment provides for, among other things, modifications to LMI’s financial maintenance covenants. The covenant related to Total Net Leverage Ratio (as defined in the Amended Credit Agreement) was waived from the date of the Amendment throughyear ended December 31, 2020. The maximum total net leverage ratio and interest coverage ratio permitted by the financial covenant is displayed in the table below:2023.

Table of Contents

In December 2022, the Company’s Board of Directors authorized the repurchase of up to $150.0 million in aggregate amount of the Company’s common stock under certain circumstances. The Company used approximately $75.0 million of the net proceeds from the Notes to repurchase shares of their common stock from purchasers of the Notes in privately negotiated transactions effected with or through one of the initial purchasers or its affiliate. The purchase price per share of the common stock repurchased in such transactions was equal to the closing sale price per share of the Company’s common stock on the date of the offering memorandum used for the Notes, which was $56.01 per share. Following this initial repurchase, the Company may from time to time repurchase additional shares of their common stock. In the year ended December 31, 2022, the Company purchased approximately 1.3 million shares of their outstanding common stock for $75.0 million as part of the program. The Company did not purchase any shares of its outstanding common stock in the year ended December 31, 2023.

Operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Lease agreements with lease and non-lease components are accounted for separately. As the Company’s leases do not provide an implicit rate, the Company used the incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.
The Company assumed 2two operating leases as a result of the Progenics acquisition related to office space at the World Trade Center in New York City, pursuant to a lease agreement expiring in September 2030 (the “WTC Lease”), and a radiopharmaceutical manufacturing facility in Somerset, New Jersey, under a sublease agreement expiring in November 2028, which were recorded as of June 19, 2020, for $18.6 million and $0.6 million, respectively. The Company entered into an operating lease related to office space in Somerset, New Jersey, under a lease agreement expiring in August 2026, which was recorded in October 2021 for $0.7 million. The Company excluded the Puerto Ricoentered into an operating lease amounts classified as heldagreement in February 2022 to lease office space in Bedford, Massachusetts, under a lease agreement expiring in June 2031, which commenced and was recorded in December 2022 for sale$11.0 million.
On May 4, 2023, the Company entered into a modification to the operating lease for office space in Bedford, Massachusetts, (the “Existing Premises”) that was executed in February 2022. The lease commenced and was recorded in December 2022 for $11.0 million and the initial term was set to expire in June 2031. The lease modification includes a lease of additional office and laboratory space at the Bedford location (the “Additional Premises”) for a term of 15 years and 4 months and extends the term of the lease for the Existing Premises to be coterminous with the term of the lease for the Additional Premises. As a result of the extended term for the Existing Premises, the Company recorded an additional right-of-use asset and liability of $6.0 million in May 2023. The modification also contains a provision to convert the rent schedule of the Existing Premises from gross to triple net in 2024, which may result in an additional adjustment to the right-of-use asset and liability. In September 2023, the landlord provided notice to the Company that its renovations of the Additional Premises were completed. As a result of the notice, the Company recorded an additional right-of-use asset and liability of $23.5 million as of December 31, 2020.September 1, 2023. To determine the value of the additional right-of-use asset and liability, the Company was required to calculate the discount rate of the lease modification. The discount rate was determined based on the expected lease term and by comparing interest rates in the market for similar borrowings with comparable credit quality of the Company. The lease for the Additional Premises allows for the extension of five years to begin immediately upon the expiration of the original term.
Leases with an initial term of 12 months or less are not recorded on the balance sheet as the Company has elected to apply the short-term lease exemption. The Company recognizes lease expense for these leases on a straight-line basis over the lease term.

In the third quarter of 2021, with respect to the office space in the World Trade Center, the Company negotiated a sublease agreement with an unrelated third party that was signed on October 11, 2021 (the “Sublease”) and has a term of nine years, which represents the remaining term of the WTC Lease. Both the WTC Lease and the Sublease are classified by the Company as operating leases. As a result of the negotiations of the Sublease, the Company determined that an impairment triggering event had occurred. Accordingly, the Company performed an undiscounted cash flow analysis related to the asset group as of September 30, 2021. Based on the undiscounted cash flow analysis, the Company determined that the asset group, including the ROU asset, had net carrying values that exceeded their estimated undiscounted future cash flows. The Company then estimated the fair value of the asset group based on its discounted cash flows. The carrying value exceeded the fair value and, as a result, the Company recorded a non-cash impairment of $9.5 million for the year ended December 31, 2021 in general and administrative expenses in the consolidated statements of operations.

Impact of the Convertible Notes
The Company considered whether the notes are participating securities through the two-class method. The Company determined that if a cash dividend is paid that is greater than the then stock price, the holder of Notes will receive cash on an if-converted basis. While this feature is considered to be a participating right; basic earnings per share is only impacted if the Company’s earning exceeds the current share price, regardless of whether such dividend is declared. During the year ended December 31, 2023, no such dividend was declared. In addition, the Company is required to settle the principal amount of the Notes in cash upon conversion, and therefore, the Company uses the if-converted method for calculating any potential dilutive effect of the conversion option on diluted net income per share, if applicable, unless the application of the two-class method is dilutive. The conversion option will have a dilutive impact on net income per share of Common Stock when the average price per share of the Company’s Common Stock for a given period exceeds the conversion price of the Notes of $79.81 per share.    
20.19. Commitments and Contingencies

contingent payments include potential milestone or contractual payment obligations contingent upon the achievement or occurrence of future milestones or events and the amounts and timing of such potential obligations are unknown or uncertain.
Legal Proceedings
From time to time, the Company is a party to various legal proceedings arising in the ordinary course of business. In addition, the Company has in the past been, and may in the future be, subject to investigations by governmental and regulatory authorities, which expose it to greater risks associated with litigation, regulatory or other proceedings, as a result of which the Company could be required to pay significant fines or penalties. The costs and outcome of litigation, regulatory or other proceedings cannot be predicted with certainty, and some lawsuits, claims, actions or proceedings may be disposed of unfavorably to the Company and could have a material adverse effect on the Company’s results of operations or financial condition. In addition, intellectual property disputes often have a risk of injunctive relief which, if imposed against the Company, could materially and adversely affect its financial condition or results of operations. If a matter is both probable to result in material liability and the amount of loss can be reasonably estimated, the Company estimates and discloses the possible material loss or range of loss. If such loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

On January 31, 2022,26, 2024, the Company entered into a global settlement agreement with Pharma AG (“Novartis”),was sued in the United States District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. (“AAA”), Endocyte, Inc. (“Endocyte”) and certainAdvanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the filing of their affiliates (the “Novartis Agreement”) to settle certain disputes betweenour ANDA and Paragraph IV certification, consistent with the parties, as further described below:
German PSMA-617 Litigation
On November 8, 2018, Molecular Insight Pharmaceuticals, Inc., a subsidiary of Progenics (“MIP”), filed a complaint against the University of Heidelberg (the “University”) in the District Court in Mannheim, Germany (the “German District Court” and, such litigation, the “German Litigation”). In this Complaint, MIP claimed that the discovery and development of PSMA-617 was related to work performed under a research collaboration sponsored by MIP. MIP alleged that the University breached certain contracts with MIP and that MIP is the co-owner of inventions embodied in certain worldwide patent filings related to PSMA-617 that were filedprocess established by the University. On February 27, 2019, Endocyte, a wholly owned subsidiaryHatch-Waxman Act. Because the outcome of Novartis, filed a motion to intervene in the German Litigation. Endocytelitigation is the exclusive licensee of the patent rights that are the subject of the German proceedings.
In connection with this dispute, MIP filed a Confirmation of Ownership with the United States Patent and Trademark Office (“USPTO”) for certain U.S. patent applications filed by the University to support MIPs claim that it is the co-owner of these pending U.S. patent applications (the “Ownership Claim”).
On February 27, 2019, the German District Court set €0.4 million as the amount MIP must deposit with the German District Court as security in the event of an unfavorable final decision on the merits of the dispute. On August 24, 2020, the German District Court issued its decision dismissing MIP’s claims, stating that MIP failed to discharge its burden of proof in the matter.
MIP filed a Notice of Appeal of the German District Court’s decision on September 24, 2020 and filed its appeal brief on November 26, 2020. The University and Endocyte each filed oppositions to MIP’s Notice of Appeal on March 12, 2021 and an oral hearing for the appeal was scheduled for September 28, 2022, at the Higher Regional Court Karlsruhe.
Pursuant to the terms of the Novartis Agreement, the German Litigation was dismissed and the Ownership Claim withdrawn.
Post-Grant Review Proceeding
On February 4, 2021, AAA, a wholly-owned subsidiary of Novartis and parent of Endocyte, filed a petition for post-grant review of U.S. Patent No. 10,640,461 (the “’461 patent”) with the Patent Trial and Appeal Board (“PTAB”) of the USPTO. The ’461 patent is owned by MIP. In the petition, AAA challenged the patentability of certain claims of the ’461 patent. The PTAB instituted Post-Grant Review proceedings (the “PGR Proceeding”) on July 29, 2021. Pursuant to the terms of the Novartis Agreement, the PGR Proceeding will be terminated.
Global Settlement Agreement
In addition to the dismissal of the German Litigation, the withdrawal of the Ownership Claim and the termination of the PGR Proceeding, under the Novartis Agreement, the parties will, among other things, cross-license certain patent rights to one another, and Novartis will make a $24.0 million lump sum payment touncertain, the Company and also reimburse the Company for certain fees and expenses the Company is required to pay to the University in connection with the German Litigation.
RELISTOR European Opposition Proceedings
In October 2015, Progenics received notices of opposition to 3 European patents relating to methylnaltrexone: EP1615646, EP2368553 and EP2368554. Notices of opposition were filed separately at the European Patent Office (the “EPO”) by each of Actavis Group PTC ehf and Fresenius Kabi Deutschland GmbH. Between May 11, 2017 and July 4, 2017, the Opposition Division of the EPO (the “Opposition Division”) provided notice that the 3 European patents wouldcannot predict how or when this matter will ultimately be revoked. Each of these matters was appealed to the Appeal Board of the EPO. On November 13, 2020, Progenics withdrew the appeal for EP2368553 and EP2368554. Notices of termination of the proceedings with revocation of the patent were issued on November 23, 2020 for both patents.
Progenics continued its appeal on the revocation of the third patent, EP1615646. Oral proceedings for EP1615646 were held at the Appeal Board of the EPO on September 22, 2020. The revocation decision under appeal was set aside and the case was remitted to the Opposition Division for further prosecution. An oral hearing was held before the Opposition Division on September 27, 2021. The Opposition Division issued its final written opinion on November 11, 2021, indicating that the patent will be maintained in amended form. The final written decision of the Opposition Division was appealable to the Appeal Board of the EPO by either party. Progenics appealed this decision on January 20, 2022 to hold open its option to file Grounds for Appeal. Given that neither opponent filed an Notice of Appeal, Progenics intends to withdraw its notice to allow the patent to issue in amended form.

21. Acquisition of Assets
On February 6, 2023, the Company acquired Cerveau. Cerveau holds the rights under a license agreement to develop and 2019, respectively.commercialize MK-6240, an investigational second-generation F 18-labeled positron emission tomography (“PET”) imaging agent that targets Tau tangles in Alzheimer’s disease. The Company determined that upon review of the Cerveau acquisition, the transaction did not meet the definition of a business combination and is therefore treated as an asset acquisition.
In February 2023, the Company made an upfront payment of approximately $35.3 million to the stockholders of Cerveau (the “Selling Stockholders”) and paid the Selling Stockholders an additional $10.0 million in May 2023 upon the successful completion of a technology transfer. The Company could pay up to an additional $51.0 million in milestone payments upon achievement of specified U.S. regulatory milestones related to MK-6240. The Selling Stockholders are also eligible to receive up to $1.2 billion in sales milestone payments upon the achievement of specified annual commercial sales thresholds of MK-6240 in the event the Company pursues commercialization, as well as up to $13.5 million in research revenue milestones upon achievement of specified annual research revenue thresholds. Additionally, the Company will pay to the Selling Stockholders up to double-digit royalty payments for research revenue and commercial sales. Research revenue is derived from existing partnerships with pharmaceutical companies that use MK-6240 in clinical trials and includes milestone and dose-related payments. The purchase agreement pursuant to which the Company purchased Cerveau specifies, among other things, that certain members of the Selling Stockholders will also provide transition and clinical development services for a prescribed time following the closing of the transaction.
In December 2022, the Company made upfront payments of $260.0 million to POINT as a part of an asset acquisition with the potential for additional milestone payments of approximately $1.8 billion between the two licensed assets based on U.S. Food and Drug Administration (“FDA”) approval and net sales and commercial milestones.
Under the terms of the PNT2002 License Agreement, Lantheus Two paid POINT an upfront cash payment of $250.0 million, and could pay up to an additional $281.0 million in milestone payments upon the achievement of specified U.S. and ex-U.S. regulatory milestones related to PNT2002. POINT is also eligible to receive up to $1.3 billion in sales milestone payments upon the achievement of specified annual sales thresholds of PNT2002.
Under the terms of the PNT2003 License Agreement, Lantheus Three paid POINT an upfront cash payment of $10.0 million, and could pay up to an additional $34.5 million in milestone payments upon the achievement of specified U.S. and ex-U.S. regulatory milestones related to PNT2003. POINT is also eligible to receive up to $275.0 million in sales milestone payments upon the achievement of specified annual sales thresholds of PNT2003.
Additionally, the Company will pay POINT royalties on net sales, beyond certain financial thresholds and subject to conditions, of 20% for PNT2002 and 15% for PNT2003. Costs of IPR&D projects acquired as part of an asset acquisition that have no alternative future use are expensed when incurred, and therefore, a charge of $260.0 million was recognized in research and development expenses during the year ended December 31, 2022.
22. Segment Information
In the first quarter of 2021, the Company completed the evaluation of its operating and reporting structure, including the impact on the Company’s business of the acquisition of Progenics described in Notes 1 and 8, and the sale of the Puerto Rico subsidiary in the first quarter, which resulted in a change in operating and reportable segments. The Company now operates as 1one business segment: the development, manufacture and sale of innovative diagnostic and therapeutic products that assist clinicians in the diagnosis and treatment of heart disease, cancer and other diseases. This conclusion reflects the Company’s focus on the performance of the business on a consolidated worldwide basis.segment. The results of this operating segment are regularly reviewed by the Company’s chief operating decision maker, the President and Chief Executive Officer. The Company’s chief operating decision maker does not manage any part of the Company separately, and the allocation of resources and assessment of performance are based on the Company’s consolidated operating results.

23. Subsequent EventsEvent
On January 31, 2022,9, 2024, the Company entered into multiple strategic agreements with Perspective Therapeutics, Inc.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of Lantheus Holdings, Inc.
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Lantheus Holdings, Inc. and subsidiaries (the “Company”) as of December 31, 2021,2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021,2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2021,2023, of the Company and our report dated February 24, 2022,22, 2024, expressed an unqualified opinion on those financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting
121119

Table of Contents

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
