PART I

ITEM 1. BUSINESS

Overview

EyePoint Pharmaceuticals (Nasdaq: EYPT) is a clinical-stage biopharmaceutical company committed to developing and commercializing therapeutics to help improve the lives of patients with serious eye disorders.retinal diseases. The Company's pipeline leverages its proprietary bioerodible Durasert E®™ technology (Durasert)(Durasert E™) for sustained intraocular drug delivery including delivery ofdelivery. The Company’s lead product candidate, EYP-1901, is an investigational sustained delivery intravitreal treatment currentlyfor anti-vascular endothelial growth factor (anti-VEGF) mediated retinal diseases combining vorolanib, a selective and patent-protected tyrosine kinase inhibitor with Durasert E™. Additional pipeline programs include EYP-2301, a promising TIE-2 agonist, razuprotafib, f/k/a AKB-9778, formulated in Phase 2 clinical trials.Durasert E™ to potentially improve outcomes in serious retinal diseases. The proven Durasert® drug delivery platformtechnology (Durasert®) has been safely administered to thousands of patients'patient eyes across four U.S. FDAproducts approved products, including YUTIQ® for the treatment of posterior segment uveitis, which is currently marketed by the Company.U.S. Food and Drug Administration (FDA). EyePoint Pharmaceuticals is headquartered in Watertown, Massachusetts.

The Durasert allows® technology (Durasert) provides for the development of a miniaturized solid cylinder of drug for sustained “zero-order kinetics” releasethat can be delivered through a singlestandard intravitreal (IVT) injection in the physician’sphysician office. A Durasert intravitrealIVT insert iscan be designed to provide consistent, sustained intravitreal delivery“zero-order kinetics” release of a drug over a period of months to years and can generally be tailored tofor each drug and disease indication. Durasert® inserts can be developed in non-erodible formulations or in bioerodible formulations using Durasert E™.

EYP-1901 is an investigational product and our lead pipeline program deploying a bioerodible Durasert insert of vorolanib, a selective and patented tyrosine kinase inhibitor (TKI), that potentially bringshas the potential to bring a new mechanism of action and treatment paradigm for anti-VEGF mediated serious eye diseases beyond existing anti-vascular endothelial growth factor (VEGF) large molecule therapies. EYP-1901 is presently in Phase 2 clinical trials as a sustained delivery treatment for wet age-related macular degeneration (wet AMD), the leading cause of vision loss among people 50 years of age and older in the United States, and non-proliferative diabetic retinopathy (NPDR), a largely untreated disease due to limitations of available therapies. We expect to initiate a Phase 2 clinical trial in diabetic macular edema (DME) in late 2023 or early 2024.

In 2022, we reported positive twelve-month safety and efficacy data in a Phase 1 clinical trial of EYP-1901 (DAVIO), delivering the active drug vorolanib.diseases. Vorolanib acts through intracellular binding of all VEGFvascular endothelial growth factor (VEGF) receptors thereby blocking all VEGF isoforms. Vorolanib has also demonstrated encouraging neuroprotection data in preclinical in-vivo studies potentially bringing an additional treatment benefit.

EYP-1901 is presently in Phase 2 clinical trials as a sustained delivery treatment for wet age-related macular degeneration (wet AMD), non-proliferative diabetic retinopathy (NPDR), and diabetic macular edema (DME). We expect to initiate pivotal Phase 3 clinical trials in wet AMD in the second half of 2024.

In wet AMD, EYP-1901 is being developed as a sustained deliverysix-month maintenance therapy astreatment and in December 2023, we reported positive topline six-month safety and efficacy data from the Phase 2 clinical trial (DAVIO 2). DAVIO 2 is a six-month treatment.non-inferiority, randomized controlled, three-arm clinical trial comparing two doses of EYP-1901 (2mg and 3mg) against an aflibercept control arm. Data from the DAVIO 2 clinical trial demonstrated that 53%EYP-1901 achieved all primary and secondary endpoints including;

In NPDR, we believe EYP-1901 has the potentialis being developed as a once-yearlypotential nine-month treatment option.for this disease. We completed enrollment in the Phase 2 clinical trial for NPDR (PAVIA) in May of 2023 and expect topline data in the second quarter of 2024.

OurIn January 2024, we announced the first patient dosing in the Phase 2 clinical trial of EYP-1901 in DME and anticipate topline data in the first quarter of 2025.

In May 2023, we completed our transition to a clinical-stage biopharmaceutical company with the license of our commercial product, YUTIQ®, to Alimera Sciences Inc., for $82.5 million plus potential royalties on future revenues beginning in 2025. YUTIQ®

is a once every three-year treatment for chronic non-infectious uveitis affecting the posterior segment of the eye that utilizes a non-erodible formulation of Durasert.Durasert®. YUTIQ® was launched in the U.S. in 2019 and we have focused on its use by both uveitis and retinal specialist physicians.2019.

We continue to evaluate potential pipeline product candidates through internal discovery efforts, research collaborations and in-licensing arrangements to build our pipeline.

The ongoing COVID-19 coronavirus pandemic (the Pandemic) has had a material and adverse impact on the Company’s business pursuant to a reduction in physician office visits impacting YUTIQ, specifically in early 2022. Going forward, the duration and full extent to which the Pandemic impacts the Company’s business, revenues, financial condition and cash flows depend on future developments that are highly uncertain, subject to change and are difficult to predict, including new information that may emerge concerning the Pandemic, and may cause intermittent or prolonged periods of reduced patient services at the Company’s customers’ facilities, which may negatively affect customer demand. The Company’s revenues, financial condition and cash flows may be adversely affected in the future as well. The Company is continuously monitoring the Pandemic and its potential effect on the Company’s financial position, results of operations and cash flows. Although the U.S. government has announced its intention to terminate the public health crisis associated with the Pandemic as of May 2023, there remains an uncertainty about the potential future impact of the Pandemic on the Company’s business. This uncertainty could have an impact in future periods on certain estimates used in the preparation of the Company’s periodic financial results, including reserves for variable consideration related to product sales, realizability of certain receivables and assessment for excess or obsolete inventory. Uncertainty around the extent and length of time of the Pandemic, and any future related financial impact cannot be reasonably estimated at this time.Pipeline

Our Pipeline and Commercial Products

The following table describes the stage of each of our programs:

Strategy

Our goal is to become a leader in the development and commercialization of innovative sustained delivery therapeutics to help improve the lives of patients with serious eye disorders. The key elements of our strategy include:

The Unmet Need in the Treatment of Eye Disease – Duration of Action

We are primarily focused on diseases affecting the posterior segment of the eye, with particular attention on retinal disease. We leverage our best-in-class sustained delivery Durasert® technology to achieve improved outcomes with more convenient dosing regimens. Diseases of the retina and posterior segment of the eye include wet AMD, DR, and DME and other indications including orphan diseases and certain cancers.

Our lead pipeline program, EYP-1901, is initially focused on improving the treatment of wet AMD, DRNPDR, and DME and theseDME. These VEGF mediated diseases share an underlying propensity to cause leakage from either pre-existing damaged blood vessels or new vessels (neovascularization), that, if untreated, can lead to severe visual loss.

These conditions are generally treated locally with frequent large molecule anti-VEGF ligand blocking intravitreal injections. While these treatments have a positive history of safety and initial efficacy, the need for frequent injections hampers long term visual outcomes. Many patients with retinal or other posterior segment diseases such as non-infectious uveitis require lifelong treatment and interruptions in therapy can result in disease reactivation and permanent visual loss. Accordingly, monthly or bi-monthly injections are not an effective long term means of delivering a steady state dose to the site of disease for many patients. Finally, the risk of patient non-compliance increases when treatment involves multiple products or complex or painful dosing regimens, as patients age or suffer cognitive impairment or serious illness, or when the treatment is lengthy or expensive.

Drug delivery for treating ophthalmic diseases in posterior segments of the eye is a significant challenge. Due to the effectiveness of the blood-eye barrier, it is difficult for systemically (orally or intravenously) administered drugs to reach the retina in sufficient quantities to have a beneficial effect without causing adverse side effects to other parts of the body.

Due to the drawbacks of frequent intravitreal injections, we believe the developmentdelivery of methods to deliver drugs to patients in a more precise, micro dose zero order release kinetics over longer periods of time with Durasert® can satisfy a large unmet medical need

6

for both patients and physicians. In addition, with less frequent injections, we believe patients will be able to better comply with their prescribed treatment regimen as the burden of having to frequently go into the physician’s office for eye injections, usually over a lifetime after diagnosis, presents issues for patients. Further, we are focused on bringing new mechanisms of action to the treatment of disease in addition to the current

standard of care. Unlike many chronic diseases that are treated with drugs addressing multiple mechanisms of action, most retinal diseases are currently addressed using a single mechanism of action.

Durasert Technology Platform

Our current Durasert® technology platform uses proprietary sustained release technology to deliver drugs in the eye over periods of months to years through a single intravitreal (IVT) injection. To date, four products utilizing successive generations of the Durasert® technology have been approved by the FDA. In addition to our own YUTIQ, theseThese products include YUTIQ® (fluocinolone acetonide intravitreal implant or FA 0.18 mg) and ILUVIEN (FA intravitreal implant) 0.19 mg, which are both licensed to Alimera Sciences Inc. (Alimera), and Retisert® (FA intravitreal implant)implant 0.59 mgmg) and Vitrasert® (ganciclovir)(ganciclovir intravitreal implant 4.5 mg,mg), which are both licensed to Bausch & Lomb. Earlier ophthalmic products that utilize the Durasert® technology, Retisert and Vitrasert, are surgically implanted; while ILUVIEN and YUTIQ® were designed to be injecteddelivered IVT during a physician office visit.

The Durasert® technology allows for the production of a solid, injectable, sustained release insert of a drug compound. All four FDA-approved Durasert® products utilize a non-erodible formulation of Durasert.Durasert®. For these products, the drug core matrix is coated with one or more polymer layers, and the permeability of those layers and other design aspects control the rate and duration of drug release. By changing elements of the design, we can alter both the rate and duration of release to meet different therapeutic needs.

EYP-1901 deploys a bioerodible formulation of the Durasert technology.technology, Durasert EÔ. In this formulation, the drug core matrix remains essentially unchanged, however, the non-erodible polymer layers are not utilized. This allows the solid insert to potentially deliver higher doses of drug and for the remaining core matrix to be fully bio eroded after the drug is fully released.

Our Durasert® technology platform is designed to provide sustained delivery of drugs for ophthalmic diseases and conditions with the following features:

Our Product Candidates

EYP-1901 for wet AMD, NPDR and DME

EYP-1901 is an investigational product deploying a bioerodible Durasert insert of vorolanib, a selective and patent protected TKI, that potentially brings a new mechanism of action and treatment paradigm for serious eye diseases beyond existing anti-VEGF large molecule ligand blocking therapies. EYP-1901 utilizes our bioerodible Durasert EÔ technology. We have reported positive safety and efficacy data for EYP-1901 in our Phase 12 DAVIO clinical trial and we are currently developingevaluating EYP-1901 in Phase 2 clinical trials for wet AMD (DAVIO 2) NPDR (PAVIA) and NPDR. ADME (VERONA). The Phase 2 clinical trial in DME is anticipated to initiate in late 2023 or earlyenrolled its first patient on January 9, 2024.

Vorolanib acts through intracellular binding of all VEGF receptors thereby blocking all VEGF isoforms, the main driver of the proliferation of blood vessels that are the hallmark of wet AMD and other retinal diseases. In addition to the safety and efficacy demonstrated in the DAVIO clinical trial, vorolanib has also demonstrated encouraging neuroprotection data in preclinical in-vivo studies potentially bringing an additional treatment benefit. Prior to in-licensing by EyePoint,the Company, vorolanib was previously studied in Phase 1 and 2 clinical trials as an orally delivered therapy for the treatment of wet AMD and data from these trials demonstrated a positive clinical signal and no ocular toxicity.

Market Opportunity in Wet Age-Related Macular Degeneration (wet AMD)wet AMD

Wet AMD occurs when new, abnormal blood vessels grow under the retina. These vessels may leak blood or other fluids, causing scarring of the macula. This form of AMD is less common but much more serious. AMD is one of the major causes of vision loss of the total vision impairment globally.

7

As the proportion of people in the U.S. age 65 and older grows larger, more people are developing age-related diseases such as AMD. From 2000-2010, the number of people with AMD grew 18 percent, from 1.75 million to 2.07 million. By 2050, the estimated

number of people with AMD is expected to more than double from 2.07 million to 5.44 million. White Americans are expected to continue to account for the majority of cases. However, Hispanics are expected to account for the greatest rate of increase, with a nearly six-fold rise in the number of expected cases from 2010 to 2050.

Age is the greatest risk factor for developing AMD and individuals aged 50+ are more prone to the disease. Among all AMD patients in the United States, wet AMD accounts for only 10% of cases, yet it alone accounts for 90% of legal blindness.

There are several effective and safe treatments for wet AMD available on the market, including large molecule anti-VEGF intravitreal injectable drugs marketed under the brands names Lucentis, Eylea, Eylea HD, Vabysmo, Beovu, and Avastin (off label use). However, these treatments must be injected in a physician’s office either monthly, bi-monthly or in some patients every three to four months, which can cause inconvenience and discomfort and often lead to reduced compliance and poor outcomes. The branded drug, SUSVIMO™, a port delivery technology for ranibizumab, was approved by the FDA in 2021 and requires an initial surgical placement of the port. Genentech voluntarily recalled Susvimo in October 2022 and all new implants have been paused. The issue is the septum dislodges preventing the PDS implant to be refilled. It is currently not known when Susvimo will be commercially available again. Genentech initially said it would be back on market “in a year or so.”

Separate published studies using real world data (one study in the U.S. and another that includes Canada, France, Germany, Ireland, Italy, the Netherlands, UK, and Venezuela) indicate that despite initial efficacy, approved wet AMD treatments still result in vision loss over time.

We believe that EYP-1901, if approved as a potential six-month sustained delivery maintenance therapy, has the potential to offer wet AMD patients a convenientsafe and effective treatment option with a unique mechanism of action.

Market Opportunity in Non-Proliferative Diabetic Retinopathy (NPDR)

Diabetic retinopathy (DR) is a frequent complication of diabetes mellitus. Slow but progressive changes in the small blood vessels of the retina may cause no symptoms or only mild vision problems in early stages. The disease progresses from NPDR to proliferative diabetic retinopathy (PDR). At any stage, retina bleeding and fluid accumulation leadleads to DME which can cause blindness. Both PDR and DME are common DR complications associated with the progression of the disease. Diabetes is the leading cause of new cases of blindness in adults. This is a growing problem as the number of people living with diabetes increases, so does the number of people with impaired vision due to NPDR.

The central retina area that is located between the main branches (superior and inferior arcades) of the central retinal vessels in the eye is known as the “macular area.”area”. The retina beyond this is considered “peripheral retina.”retina”. The central retinal area can develop abnormal findings. These findings can be present in the non-proliferative or the proliferative forms of the disease. These changes in the macula include the presence of abnormally dilated small vessel outpouchings (called microaneurysms), retinal bleeding (retinal hemorrhages) and yellow lipid and protein deposits (hard exudates). With DME, the macula can get thicker than normal.

NPDR can be classified into mild, moderate or severe stages based upon the presence or absence of retinal bleeding, abnormal venous beading of the vessel wall (venous beading) or abnormal vascular findings (intraretinal microvascular anomalies or IRMA). NPDR progresses to PDR and/or DME, which is a major cause of vision loss in a diabetic eye. No treatment is typically administered at the NPDR stages. A treatment with a sustainable dosing regimen that slows or prevents progression of NPDR to PDR or DME could help reduce the vision threatening effects of diabetic eye disease.

Market Opportunity in Diabetic Macular Edema (DME)

DME is triggered by DR, a well-known complication of diabetes. DR is caused by long-term damage to the retina’s small blood vessels. The leakage of fluid into the retina may lead to swelling of the surrounding tissue, including the macula. If left untreated, fluid can leak into the macula’s center, called the fovea, the part of the eye where sharp, straight-ahead vision occurs. The fluid makes the macula swell, blurring vision. This condition results in DME. DME can occur at any stage of DR, although it is more likely to occur later with the disease’s progression.

Common signs and symptoms of DME include dark spots like a smudge on glasses or gaps that may appear in the vision, blurred vision, double vision, faded colors, or the affected person may find bright light or glare difficult. The American Academy of Ophthalmology (AAO) estimates that nearly 80% of Type 1 diabetics and 50% of Type 2 diabetics will have developed DR after living with diabetes for 15 and 20 years, respectively.

Per the March 3, 2022, Journal of American Medical Association of Ophthalmology, DR is the leading cause of incident blindness in US adults aged 20 to 74 years old and DME can occur with any stage of DR. DR and DME affect 28.5% and 3.8%, respectively, of US adults, 40 years and older, with diabetes.

The most common treatments of DME are anti-VEGF Drugs,drugs, corticosteroids, and laser photocoagulation. Topical nonsteroidal anti-inflammatory drugs (NSAIDs), in the form of eye drops, are sometimes used either before or after cataract surgery to prevent the development of macular edema. Currently, intravitreal anti-VEGF agents are the preferred first-line treatment for DME.

Clinical Development

The EYPT-1901 Phase 1 DAVIO clinical trial (DAVIO) was a dose escalation trial that enrolled 17 wet AMD patients across four separate doses. The primary endpoint of the trial was safety, and key secondary endpoints were best corrected visual acuity (BCVA) and central subfield thickness.thickness (CST) measured by optical coherence tomography (OCT).

In November 2021, we reported positive interim six-month safety and efficacy data for the DAVIO clinical trial. There were no ocular Serious Adverse Events (SAEs)SAEs reported, no drug-related systemic SAEs reported, and all ocular adverse events (AEs) were ≤ grade 2; the only grade 3 AE was not drug-related. Regarding efficacy, stable visual acuity (VA) and optical coherence tomography (OCT)OCT and a clinically significant reduction in treatment burden of 75% was observed with a median time to rescue of six months. The six-month interim data also reported that 53% of patients in the trial did not require a supplemental anti-VEGF treatment up-to the six-month visit.

In July 2022, we updated the results of the DAVIO clinical trial through 12-months reporting continued positive safety and efficacy results. This included a continuation of a clinically significant reduction in treatment burden of 73% at 12 months. The data also reported that 35% of patients in the trial did not require a supplemental anti-VEGF treatment up-to the twelve-month visit.

We initiatedDAVIO 2 is a multi-center randomized, double-masked controlled Phase 2 clinical trial forof EYP-1901 forin previously treated patients with wet AMD (DAVIO 2)AMD. Originally designed to enroll 144 patients, the trial enrolled 160 patients in total due to strong investigator and top-line datapatient interest. All enrolled patients were previously treated with a standard-of-care anti-VEGF therapy and were randomly assigned to one of two doses of EYP-1901 (approximately 2 mg or 3 mg) or an aflibercept control. EYP-1901 is anticipateddelivered with a single intravitreal injection in the fourth quarterphysician's office, similar to current FDA approved anti-VEGF treatments. The primary non-inferiority efficacy endpoint was change in BCVA compared to the aflibercept control, approximately six-months after the EYP-1901 injection. Secondary endpoints include safety, reduction in treatment burden, mean change in CST as measured by OCT, the percent of eyes that remain free of supplemental anti-VEGF injections, and number of aflibercept injections in each group.

DAVIO 2 top line results at week 32 were released on December 4, 2023. In summary, the study indicated:

The DAVIO 2 study is ongoing with continued patient follow up through week 56:

The PAVIA NPDR Phase 2 clinical trial is expected to enroll approximately 144 patients acrossa three arms comprised ofarm trial with two separate doses of EYP-1901, with an afliberceptgiven as single injection on Day 1, and a sham control. In addition,PAVIA is evaluating EYP-1901 as a potential nine-month treatment in NPDR and the trial completed enrollment of 77 patients. A summary of the trial includes:

The PAVIA topline results are anticipated in the second quarter of 2024.

The VERONA DME Phase 2 clinical trial, in NPDR (PAVIA) was initiated in the third quarter of 2022, following the initiation of the Phase 2 wet AMD trial. The PAVIAis a three arm trial is expected to enroll approximately 105 patients across three arms comprised ofwith two separate doses of EYP-1901 and an aflibercept control. VERONA is evaluating EYP-1901 as a sham control.potential six-month treatment in previously treated DME patients. The two EYP-1901 doses are administered as a single injection on Day 1 following the aflibercept injection on the same visit. The trial enrolled its first patient on Jan 9, 2024, and topline results are anticipated in the first quarter of 2025. A summary of the trial includes:

Market Opportunity

Chronic non-infectious uveitis affecting the posterior segment of the eye is an inflammatory disease that afflicts people of all ages, producing swelling and destroying eye tissues, which can lead to severe vision loss and blindness. This disease affects between 60,000 to 100,000 people each year in the U.S. and causes approximately 30,000 new cases of blindness every year. The standard of care treatment for this disease typically involves the use of short-acting corticosteroids to reduce uveitic flares followed by additional treatments of sustained release, lower dose steroids to minimize the risk of further flares.

Recent Clinical Development Highlights

CALM real world registry study is ongoing and collecting real world data on YUTIQ for the Treatment of Chronic Non-Infectious Uveitis Affecting the Posterior Segment. There were two initial baseline posters presented at the American Society of Retina Specialists (ASRS) and Retina Society conferences in 2021. At present, data for 188 eyes of 122 patients have been logged in the registry. Various posters with follow-up data will be presented at ARVO 2023 Meeting and at the ASRS 2023 meeting. Additional data will be analyzed and presented or published as the study continues and the data are analyzed.

In the second quarter of 2022, we dosed the first patient in a Phase 4 Study, the SYNCRONICITY study, of YUTIQ® (fluocinolone acetonide intravitreal implant) 0.18 mgwas approved and sales commenced in China in 2022 and we are entitled to royalties on product sales by Ocumension. Alimera is now responsible for the treatment of Chronic Non-Infectious Posterior Segment Uveitis. This is a 2-year, prospective, open-label, uncontrolled, safetyall commercial, regulatory, and efficacy study. Its objective isdistribution activities related to evaluate the safety and efficacy of YUTIQ® for the management of chronic non-infectious posterior segment uveitis that has responded to previous steroid therapy. We plan to enroll approximately 125 subjects with at least 100 subjects expected to complete two years of follow-up. The primary efficacy endpoints will be evaluated at six months and will be as follows: 1) Mean change from baseline in BCVA letter score in the study eye measured by Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity charts and 2) Mean change from baseline central subfield thickness (CST, also known as central foveal thickness) measured by spectral domain optical coherence tomography (SD-OCT) in the study eye. As of January 2023, 25% patient recruitment has been attained, as the clinical trial continues, data will be presented or published and when appropriate data are analyzed.

Intellectual Property

We own the rights for. YUTIQ® in the U.S. and all foreign jurisdictions and have licensed these rights in EMEA and Mainland China, Hong Kong, Macau and Taiwan. In August 2020, we expanded the out-license agreement with Ocumension to include South

10

Korea and other jurisdictions across Southeast Asia. We have patent rights for YUTIQis a once every three-year treatment utilizing a non-erodible formulation of our proprietary Durasert® in the U.S. through at least August 2027 and internationally through dates ranging from October 2024 to May 2027.

Sales and Marketing

YUTIQ was grantedtechnology that is administered during a permanent and specific J-code by the Centers for Medicare & Medicaid Services (CMS), effective October 1, 2019. Approximately 20 Key Account Managers (KAMs) are dedicated to calling on uveitis and retinal specialists across the U.S. as of February 28, 2023.

In 2020, the retinal and uveitis markets were impacted by the Pandemic as most teaching hospitals and many independent practices significantly reduced the patient access and flow into the clinics. As a result, many patients were unable to receive the treatments needed to control the inflammatory disease in a timely manner. We started to see customer demand return in the third and fourth quarter of 2020.

In 2021, the pandemic continued to impact the ability of KAMs to promote YUTIQ, especially in the institutional segment. However, there was a significant expansion of utilization in the retinal segment and the fourth quarter of 2021 saw record sales and customer demand. This expansion within the retinal market continued throughout 2022 and this drove record sales and customer demand for YUTIQ.physician office visit.

DEXYCU®

DEXYCU® (dexamethasone intraocular suspension) 9%, for intraocular administration, was approved by the FDA in February 2018 for the treatment of post-operative ocular inflammation and commercially launched in the U.S. in March 2019 with a primary focus on its use immediately following cataract surgery. DEXYCU® is administered as a single dose directly into the surgical site at the end of ocular surgery and is the first long-acting intraocular product approved by the FDA for the treatment of post-operative inflammation. DEXYCU utilizes our proprietary Verisome® drug-delivery technology, which allows for a single intraocular injection that releases dexamethasone, a corticosteroid, for up to 22 days.

Market Opportunity

DEXYCU is approved for ocular post-surgical inflammation. The initial market we have focused on for DEXYCU is post-operative inflammation associated with cataract surgery as there were approximately 3.8 million cataract surgeries performed in 2018 in the U.S.

Due to the elimination of separate pass-through reimbursement by CMSthe Centers for Medicare and Medicaid Services (CMS) as described below, the market opportunity for this product is significantly impacted and, accordingly, the Company has minimizedterminated promotion of this program in the U.S.

Clinical Development Highlights

Retrospective study data were presented at the Association for ResearchU.S in Vision and Ophthalmology (ARVO) and American Society of Cataract and Refractive Surgery (ASCRS) 2021. This completed study was a multicenter retrospective study of real world data from use of DEXYCU. ARVO 2021 data from this study highlighted real world data in patients with a history of glaucoma treated with DEXYCU for inflammation control following cataract surgery. Anti-inflammatory efficacy, as measured by anterior chamber cell (ACC) count clearing and safety with regard to intraocular pressure (IOP) elevation were similar in patients with glaucoma to the full study population.

Intellectual Property

We own the worldwide rights to all indications for DEXYCU® and in January 2020 we out-licensed clinical development, regulatory, reimbursement and distribution rights to Ocumension for the product in Mainland China, Hong Kong, Macau and Taiwan. In August 2020, we expanded the out-license agreement with Ocumension to include South Korea and other jurisdictions across Southeast Asia.

Sales and Marketing

Effective January 1, 2022, our commercial alliance partner, ImprimisRx, assumed responsibility for all sales and marketing activities for DEXYCU in the U.S. and absorbed the majority of our DEXYCU commercial organization. We continued to recognize net product revenue and maintained manufacturing and distribution responsibilities for DEXYCU along with non-sales related regulatory compliance. We paid ImprimisRx a commission based on the net sales of DEXYCU and retained all commercial rights and the NDA for DEXYCU. ImprimisRx utilized their internal sales representatives and their numerous indirect representatives to promote DEXYCU to their existing cataract surgery customers. The contract with ImprimisRx was terminated on December 31, 2022.

In October 2018, DEXYCU was granted “pass through status” by CMS for reimbursement of DEXYCU separate from the cataract procedure payment bundle for a 3-year period. The 3-year period commenced in April 2019, the quarter of the first claim for reimbursement for DEXYCU was submitted to CMS and was to expire in March 2022. In addition, in November 2018, CMS assigned a specific and permanent J-code for DEXYCU, effective January 1, 2019, that enabled reimbursement across all types of payers. In the 2022 CMS Hospital Outpatient Prospective Payment System Final Rule, which was released in November of 2021, CMS decided that DEXYCU would receive adjusted separate payment for nine months equivalent to an extension of pass through status through December 31, 2022 as a result of the Public Health Emergency which limited access to many therapies provided in the ASC or outpatient setting. The 2023 CMS Hospital Outpatient Prospective Payment System Final Rule did not extend DEXYCU pass through payment beyond December 31, 2022, therefore as of January 1, 2023 the payment for DEXYCU is part of the bundled surgical payment.2023.

Manufacturing

The FDA carefully regulates the quality of pharmaceuticals. The main regulatory standard for ensuring pharmaceutical quality is the Current Good Manufacturing Practice (cGMPs) regulation for human pharmaceuticals. Manufacturing of our clinical trial materials (CTM) and of our commercial products is subject to these cGMPs which govern record-keeping, manufacturing processes

and controls, personnel, quality control and quality assurance, among other activities. Incoming raw materials and components from suppliers are inspected upon arrival according to pre-specified criteria prior to use in the CTM or the commercial product. During product manufacture, in-process tests are conducted on intermediate products according to pre-specified criteria; testing is finally conducted on the finished product prior to its release. Our systems and our contractors are required to comply with cGMP requirements, and we assess compliance regularly through performance monitoring and audits.

is not commercially supported by the Company although it is still available through specialty distributors.

U.S. Market Access and Payer Reimbursement

In 2018 we recruited a team of highly experienced personnel to form our market access team. The team is comprised of our VP of Market Access and Government Affairs, Assoc. Director of Patient Access, Director of National Accounts (NAD), and Field Reimbursement Managers (FRMs) who handle the reimbursement for both YUTIQ and DEXYCU. Their roles include the discussions with payers regarding the costs and benefits of our products for their members; assisting with the addition of our products to the medical policy of payers; and providing the market with assistance regarding reimbursement queries.

We have initiated a patient assistance platform called EyePoint AssistSM to provide co-pay and coinsurance relief for eligible commercial patients.

Reimbursement for YUTIQ is® was obtained using a permanent J code, established on October 1, 2019, which enables reimbursement from both Medicare and commercial payers. In May 2023 we out-licensed YUTIQ® to Alimera. DEXYCU® had three-year pass through status with Medicare which expired effective January 1, 2023. The Company made the decision to no longer commercially support DEXYCU® from a sales and marketing perspective as of January 1, 2023, and therefore all patient assistance programs and support were also concluded concurrently. Accordingly, we now focus on reimbursement matters related to our product candidates.

U.S. Product Distribution Channel

We havepreviously established a distribution channel in the United States for the commercialization of YUTIQ® and DEXYCU® that providesprovided physicians with several options for ordering our products. This includes agreements with a nationally recognized third-party logistics provider (3PL), several distributors, and a specialty pharmacy provider for physicians who prefer to use a traditional buy-and-bill model. The 3PL provides fee-based services related to logistics, warehousing, order fulfilment, invoicing, returns and accounts receivable management. While DEXYCU® is still available through this network, all YUTIQ® product responsibilities including distribution were turned over to Alimera effective May 2023.

Research Agreements

From time to time, we enter into research agreements with third parties to evaluate our technology platforms for the treatment of ophthalmic and other diseases. We intend to continue this activity with partner compounds that could be successfully delivered with our Durasert and, potentially, Verisome technology platforms on a fee-for-service basis with the potential for future clinical and commercial milestones and royalties.

Competition

The market for products treating eye diseases is highly competitive and is characterized by extensive research efforts and rapid technological progress. We face substantial competition for our FDA-approved products and our product candidates. Pharmaceutical, drug delivery, and biotechnology companies, as well as research organizations, governmental entities, universities, hospitals, other nonprofit organizations, and individual scientists, have developed and are seeking to develop drugs, therapies, and novel delivery methods to treat diseases targeted by our products and product candidates. MostMany of our competitors and potential competitors are larger, better established, more experienced, and have substantially more resources than we or our partners have. Competitors may reach the market earlier, may have obtained or could obtain patent protection that dominates or adversely affects our products and potential products, and may offer products with greater efficacy, lesser or fewer side effects, and/or other competitive advantages. We believe that competition for treatments of eye diseases is based upon the effectiveness of the treatment, side effects, time to market, reimbursement and price, reliability, ease of administration, dosing or injection frequency, patent position, and other factors.

Many companies have or are pursuing products to treat eye diseases that are or would be competitive with EYP-1901 and YUTIQ.other pipeline products. Some of these products and product candidates include the following:

EYP-1901 for wet AMD, NPDR and DME

FDA-approved LUCENTIS® (ranibizumab), EYLEA (aflibercept)® (aflibercept 2mg), EYLEA® HD (aflibercept 8mg), VABYSMO® (faricimab) and off-label use of the cancer drug AVASTIN® (bevacizumab) are the leading treatments for wet AMD. Lucentis, Eylea, and Avastin are also used in the treatment of NDPRDR and DME. There are also two approved biosimilarFDA-approved Lucentis biosimilars mediations approved by the FDA.

In 2021, the FDA approved Susvimo, a first-of-its-kind port delivery system (PDS) with ranibizumab for the treatment of patients with wet AMD. However, in the Fall of 2022, Susvimo was taken off the market by Genentech via a voluntary recall. In January 2022, the FDA approved VABYSMO® (faricimab), a bispecific antibody Ang-2 and VEGF-Avascular endothelial growth factor-A inhibitor. Also in 2022, two ranibizumab biosimilars, Byooviz and Cimerli entered the market. The FDA also approved Beovu® brolucizumab injection on October 8, 2019.

In August 2023, the FDA approved EYLEA® HD (aflibercept 8mg) for wet AMD, DME, and DR based on the pivotal PULSAR and PHOTON trials in which EYLEA® HD demonstrated clinically equivalent vision gains to EYLEA® (aflibercept 2 mg) that were maintained with fewer injections.

In addition to FDA approved products, there are a number of investigational treatments in development including the following:

REGENXBIO Inc., and Adverum Biotechnologies, Inc., 4D Molecular Therapeutics (4DMT), 4D Molecular Therapeutics (4DMT), as well as several others in early development are developing gene therapy treatments for retinal diseases, such as wet AMD.AMD and DME. REGENXBIO is developing RGX-314,ABBV-RGX-314, a gene therapy utilizing its NAV AAV8 vector containing a gene encoding for a monoclonal antibody fragment which inhibits VEGF. Adverum is developing ADVM-022,Ixo-vec (formerly ADVM-022), a gene therapy utilizing an AAV.7m8 vector containing a gene encoding for a protein that expresses aflibercept. 4DMT is developing 4D-150 as an investigational genetic medicine using the intravitreal R100 vector for the treatment of neovascular age-related macular degeneration (wet AMD) and diabetic macular edema (DME). 4D-150 is in the randomized Phase 2 stage of the Phase 1/2 PRISM study for adults with wet AMD and in the Phase 2 SPECTRA study for adults with DME.

In addition to FDA approved products, there are a number of investigational treatments in development including the following:

Aflibercept 8 mg (high-dose Eylea) – Regeneron/Bayer

In September 2022, Regeneron Pharmaceuticals, Inc., announced that the primary endpoints were met in two pivotal trials investigating novel aflibercept 8 mg with 12- and 16-week dosing regimens in patients with DME and wet AMD.

The PHOTON trial in DME demonstrated that aflibercept 8 mg 12- and 16-week dosing regimens achieved non-inferiority in vision gains compared to the EYLEA 8-week dosing regimen. In this study, 91% and 89% of DME patients were rapidly initiated and maintained on 12- and 16-week dosing intervals (without need for regimen modification) through week 48, respectively.

In this trial, the safety of aflibercept 8 mg was consistent with the established safety profile of EYLEA. Regeneron and Bayer will submit these data to regulatory authorities in countries around the world.

OTX-TKIAXPAXLI (formerly OTX-TKI) – Ocular TherapeuticsTherapeutix, Inc.

In February 2023, Ocular TherapeuticsTherapeutix, Inc. (Ocular Therapeutix) presented 10-month data for OTX-TKI demonstrating a favorable safety and efficacy profile in a controlled Phase 1 trial of patients that were measured dry at screening. OTX-TKI utilizes axitinib, a TKI, formulated in a hydrogel and delivered through an intravitreal injection.

Ocular Therapeutics has indicated their intentionTherapeutix initiated the SOL trial and expects to advance OTX-TKI into Phase 3 trialsenroll approximately 300 evaluable wet AMD subjects who are treatment naïve in DR andthe study eye in wet AMD.the trial. The SOL trial is designed to be a multi-center, parallel-group trial. In February 2024, Ocular Therapeutix announced that it had screened the first three subjects in the SOL trial in early 2024.

Patients will be treated and followed for two years. Both studies are estimated to read out in 2023.aflibercept.

In November 2023, Kodiak Sciences also reportedannounced it was rebooting its Tarcocimab development program based on the resultsstrength of its phase 3 NPDR GLOW study. In the study, six-month dosing of tarcocimab tedromer 5 mg in moderately severe to severe NPDR met its one-year primary endpoint. Kodiak plans to conduct one additional NPDR pivotal study with a studycommercial formulation of KSI-301 for treatment of naïve wet AMD. KSI-301 was found to be not non-inferior to the control group that were treated with Eylea.tarcocimab.

OPT-302 - Opthea Limited

OPT-302 is an intravitreal agent that inhibits VEGF-Cvascular endothelial growth factor-C and VEGF-D.D. OPT-302 has been investigated in both DME and nAMD patients in combination with IVI anti-VEGF-Aanti-vascular endothelial growth factor-A (anti-VEGF-A) therapy. In Opthea’sOpthea Limited's (Opthea) randomized, double-masked, sham-controlled, phase 1b/2a trial, 153 patients with DME were treated with OPT-302 alone, in combination with intravitreal aflibercept injections, or with aflibercept alone. OPT-302 and aflibercept combination therapy yielded the largest proportion of DME patients who gained ≥10 ETDRSEarly Treatment Diabetic Retinopathy Study (ETDRS) letters from baseline to week 12.20 Opthea has initiated phase 3 trials for OPT-302 in combination with and in comparison to ranibizumab and aflibercept for nAMD patients. According to Opthea, these trials are currently enrolling.

THR-149 – Oxurion NV

Plasma kallikrein (PKal) is independent of the VEGF pathway and is also thought to promote vascular permeability and neovascularization. THR-149 is bicyclic peptide PKal inhibitor delivered via intravitreal injection currently in clinical trials for DME patients who demonstrated suboptimal response to anti-VEGF therapy. KALAHARI is a 2-part, randomized, multicenter, phase 2 study that aims to assess the dosage levels of THR-149 intravitreal injection in addition to the efficacy and safety of THR-149 compared to aflibercept injections in 126 patients with DME. In May 2023, Oxurion NV announced KALAHARI is expected to reachreached its primary endpointenrollment target of 108 patients. At that time, Oxurion announced that it anticipated topline data in Marchthe fourth quarter of 2023. Interim results presented in February 2022 revealed that over 80% of DME patients in the THR-149 high-dose arm gained ≥5 ETDRS letters and 50% of patients gained >10 ETDRS letters four months after the final THR-149 injection. 24 Centralcentral subfield thickness (CST) also remained stable at the 6-month mark.

16

Integrins are transmembrane glycoprotein receptors that play a role in cell signaling, adhesion, migration, remodeling, and proliferation and are thought to contribute to retinal pathology via modulation and integration of the VEGF and Ang/Tie2 pathways. Clinical trials exploring the efficacy of anti-integrin therapy in DME are underway, including integrin inhibitors.

THR-687 – Oxurion NV

THR-687 is an integrin receptor antagonist that inhibits avβ3, avβ5, and a5β, and demonstrated significant and rapid visual acuity gains in a multicenter, single-dose escalation phase 1 study in DME patients. INTEGRAL, a randomized, multicenter, 2-part phase 2 study evaluated the efficacy and safety of THR-687 compared to aflibercept intravitreal injections in 303 DME patients. Although THR-687 met its safety and tolerability endpoints, INTEGRAL found no significant difference in BCVA or CST, leading to the discontinuation of part B of the INTEGRAL trial.

OCS-01 - Oculis Holding AG

OCS-01 1.5% ophthalmic suspension is a topical formulation of dexamethasone that utilizes novel solubilizing nanoparticle technology to enhance bioavailability and durability of the dexamethasone solution.30solution. DIAMOND is a 2-stage, double-masked, randomized, multicenter phase 3 trial that will evaluate the safety and efficacy of OCS-01 with 2 dosing regimens in comparison to vehicle alone in 482 DME patients for 52 weeks.31 Preliminary results from DIAMOND are expectedweeks. In December 2023, Oculis Holding AG announced the first patient first visit in 2024.phase 3 DIAMOND-1 trial of OCS-01 eye drop in diabetic macular edema.

UBX1325 – Unity Biotechnology, Inc.

UBX1325 is an inhibitor of Bcl-xl, a protein that senescent cells rely on for survival. UBX1325 demonstrated a favorable safety profile and sustained improvements in visual acuity through 24 weeks in a phase 1 study of patients with advanced vascular eye disease.32 UBX1325 is currently being studied indisease.

In September, the company announced 48-week results from phase 2 BEHOLDENVISION study a multicenter, randomized, double-masked, prospectiveof UBX1325 in patients with wet AMD. Patients on combination treatment with UBX1325 and aflibercept from weeks 24-48 maintained vision gains achieved at week 24 on aflibercept alone. Then in December 2023, Unity Biotechnology, Inc. announced the first patient dosed in phase 2 trial that enrolled 62 patients to receive one 10 μgASPIRE study of UBX1325 injection or sham IVI and evaluated at 12, 24, and 48 weeks to ensure safety, efficacy, and durability.33 Sixteen-week results of the BEHOLD study arein DME with topline 16-week data expected in the second half of 2022.

YUTIQ for Posterior Segment Uveitis

Periocular and intravitreal steroid injections, and systemic delivery of corticosteroids are routinely used to treat posterior segment uveitis, which is a chronic, inflammatory condition of the eye. It is treated both aggressively and frequently by physicians in order to minimize the disease “flares,” which are the main cause of vision deterioration and potential blindness.

OZURDEX®, marketed by Allergan, is approved in the U.S. and EU for posterior segment uveitis through an intravitreal bioerodible implant that provides treatment which lasts for several months. This limited duration effectiveness of OZURDEX can result in frequent intravitreal injections of the implant.

AbbVie, Inc. has FDA approval for HUMIRA® (adalimumab) for the treatment of all types of non-infectious uveitis (intermediate, posterior and panuveitis) and it is administered subcutaneously every other week for systemic delivery. HUMIRA is a biologic that blocks tumor necrosis factor alpha, a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Humira’s retail price in the U.S. is approximately $50,000 per year.

Other companies have ongoing trials of posterior segment uveitis treatments, including Santen Pharmaceutical Co. Ltd., which received a Complete Response Letter (CRL), in December 2017 from the FDA for its filed NDA for sirolimus, which is administered through intravitreal injection every two months. Sirolimus is a mammalian target of rapamycin inhibitor and modulator of the immune system and is being developed for chronic non-infectious uveitis affecting the posterior segment of the eye. Santen initiated a Phase 3 clinical trial of sirolimus in December 2018 in the U.S. The study is entitled: LUMINA: A Phase III, Multicenter, Sham-Controlled, Randomized, Double-Masked Study Assessing the Efficacy and Safety of Intravitreal Injections of 440 ug DE-109 for the Treatment of Active, Non-Infectious Uveitis of the Posterior Segment of the Eye. The study was completed on June 8, 2022 and its primary readout is currently pending.

Clearside Biomedical Inc.’s (Clearside) CLS-TA (triamcinolone acetonide, a steroid) for macular edema associated with non-infectious uveitis has been accepted by the FDA for review and it is administered through a suprachoroidal injection administered every 12 weeks. Preliminary clinical data indicated that the suprachoroidal route may reduce the risk of increased IOP that is typically associated with intraocular injection of steroids. The results of the Phase 3 trial, presented in September 2018, indicated that while about 50% of patients experienced significant improvements in visual acuity through 24 weeks, adverse events of IOP increase were reported in about 12% of patients.

On December 19, 2018, Clearside submitted an NDA for XIPERE™ (CLS-TA) to the FDA for the treatment of macular edema associated with uveitis. On October 18, 2019, Clearside received a CRL from the FDA regarding its NDA for XIPERE. The CRL

17

included the FDA’s request for additional stability data, reinspection of the drug product manufacturer and additional data on clinical use of the final to-be-marketed SCS Microinjector™ delivery system. Clearside indicated that it expects to resubmit its New Drug Application for XIPERE to FDA for review in the firstfourth quarter of 2020. On October 23, 2019, Bausch Health Companies Inc. acquired an exclusive license for the commercialization and development of XIPERE in the United States and Canada. XIPERE was eventually approved in the U.S. in October 2021.2024.

Government Regulation

We are subject to extensive regulation by the FDA and other federal, state, and local regulatory agencies. The Federal Food, Drug and Cosmetic Act (the FD&C Act), and FDA’s implementing regulations set forth, among other things, requirements for the testing, development, manufacture, quality control, safety, effectiveness, approval, labeling, storage, record-keeping, reporting, distribution, import, export, advertising, and promotion of our products and product candidates. Although the discussion below

focuses on regulation in the U.S., we currently out-license certain of our products and may seek approval for, and market, other products in other countries in the future. Generally, our activities in other countries will be subject to regulation that is similar in nature and scope to that imposed in the U.S., although there can be important differences. Additionally, some significant aspects of regulation in the EU are addressed in a centralized way through the EMA, and the European Commission, but country-specific regulation remains essential in many respects. The process of obtaining regulatory marketing approvals and the subsequent compliance with appropriate federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources and may not be successful.

Development and Approval

Under the FD&C Act, FDA approval of an NDA is required before any new drug can be marketed in the U.S. NDAs require extensive studies and submission of a large amount of data by the applicant.

Pre-clinical Testing. Before testing any compound in human patients in the U.S., a company must generate extensive pre-clinical data. Pre-clinical testing generally includes laboratory evaluation of product chemistry and formulation, as well as toxicological and pharmacological studies in several animal species to assess the toxicity and dosing of the product. Certain animal studies must be performed in compliance with the FDA’s GLP,Good Laboratory Practice (GLP), regulations and the U.S. Department of Agriculture’s Animal Welfare Act.

INDInvestigational New Drug (IND) Application. Human clinical trials in the U.S. cannot commence until an IND, application is submitted and becomes effective. A company must submit pre-clinical testing results to the FDA as part of the IND, and the FDA must evaluate whether there is an adequate basis for testing the drug in initial clinical studies in human volunteers. Unless the FDA raises concerns, the IND becomes effective 30 days following its receipt by the FDA, and the clinical trial proposed in the IND may begin. Once human clinical trials have commenced, the FDA may stop a clinical trial by placing it on “clinical hold” because of concerns about the safety of the product being tested, or for other reasons.

Clinical Trials. Clinical trials involve the administration of a drug to healthy human volunteers or to patients under the supervision of a qualified investigator. The conduct of clinical trials is subject to extensive regulation, including compliance with the FDA’s bioresearch monitoring regulations and Good Clinical Practice, or GCP, requirements, which establish standards for conducting, recording data from, and reporting the results of, clinical trials, and are intended to assure that the data and reported results are credible and accurate, and that the rights, safety, and well-being of study participants are protected. Clinical trials must be conducted under protocols that detail the study objectives, parameters for monitoring safety, and the efficacy criteria, if any, to be evaluated. Each protocol is reviewed by the FDA as part of the IND. In addition, each clinical trial must be reviewed and approved by, and conducted under the auspices of, an Institutional Review Board, or IRB,institutional review board (IRB), for each clinical site. Companies sponsoring the clinical trials, investigators, and IRBs also must comply with, as applicable, regulations and guidelines for obtaining informed consent from the study patients, following the protocol and investigational plan, adequately monitoring the clinical trial, and timely reporting of adverse events, or AEs. Foreign studies conducted under an IND must meet the same requirements that apply to studies being conducted in the U.S. Data from a foreign study not conducted under an IND may be submitted in support of an NDA if the study was conducted in accordance with GCP and the FDA is able to validate the data.

A study sponsor is required to publicly post specified details about certain clinical trials and clinical trial results on government or independent websites (e.g., http://clinicaltrials.gov). Human clinical trials typically are conducted in three sequential phases, although the phases may overlap or be combined:

18

The sponsoring company, the FDA, or the IRB may suspend or terminate a clinical trial at any time on various grounds, including a finding that the patients are being exposed to an unacceptable health risk. Further, success in early-stage clinical trials does

not assure success in later-stage clinical trials. Data obtained from clinical activities are not always conclusive and may be subject to alternative interpretations that could delay, limit or prevent regulatory approval.

NDA Submission and Review. The FD&C Act provides two pathways for the approval of new drugs through an NDA. An NDA under Section 505(b)(1) of the FD&C Act is a comprehensive application to support approval of a product candidate that includes, among other things, data and information to demonstrate that the proposed drug is safe and effective for its proposed uses, that production methods are adequate to ensure its identity, strength, quality, and purity of the drug, and that proposed labeling is appropriate and contains all necessary information. A 505(b)(1) NDA contains results of the full set of pre-clinical studies and clinical trials conducted by or on behalf of the applicant to characterize and evaluate the product candidate.

Section 505(b)(2) of the FD&C Act provides an alternate regulatory pathway to obtain FDA approval that permits the filing of an NDA where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference. The applicant may rely to some extent upon the FDA’s findings of safety and effectiveness for an approved product that acts as the reference drug and submit its own product-specific data — which may include data from pre-clinical studies or clinical trials conducted by or on behalf of the applicant — to address differences between the product candidate and the reference drug.

The submission of an NDA under either Section 505(b)(1) or Section 505(b)(2) generally requires payment of a substantial user fee to the FDA, subject to certain limited deferrals, waivers and reductions. The FDA reviews applications to determine, among other things, whether a product is safe and effective for its intended use and whether the manufacturing controls are adequate to assure and preserve the product’s identity, strength, quality, and purity. For some NDAs, the FDA may convene an advisory committee to seek insights and recommendations on issues relevant to approval of the application. Although the FDA is not bound by the recommendation of an advisory committee, the agency usually considers such recommendations carefully when making decisions.

Our products and product candidates include products that combine drug and device components in a manner that meet the definition of a "combination product" under FDA regulations. The FDA exercises significant discretion over the regulation of combination products, including the discretion to require separate marketing applications for the drug and device components in a combination product. For YUTIQ®, FDA’s Center for Drug Evaluation and Research (CDER) had primary jurisdiction for review of the NDA, and both the drug and device components were reviewed under one marketing application. For a drug-device combination product for which CDER has primary jurisdiction, CDER typically consults with the Center for Devices and Radiological Health in the NDA review process. Whether reviewed under one application or separately, both the drug and device components of a drug-device combination product must satisfy the applicable regulatory requirements for marketing as if they were submitted for approval independently.

The FDA may determine that a Risk Evaluation and Mitigation Strategy (REMS), is necessary to ensure that the benefits of a new product outweigh its risks, and the product can therefore be approved. A REMS may include various elements, ranging from a medication guide or patient package insert to limitations on who may prescribe or dispense the drug, depending on what the FDA considers necessary for the safe use of the drug. Under the Pediatric Research Equity Act (PREA), certain applications for approval must also include an assessment, generally based on clinical study data, of the safety and effectiveness of the subject drug in relevant pediatric populations.

Before approving an NDA, the FDA will inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP, requirements and adequate to assure consistent production of the product within required specifications.

The FDA conducts a preliminary review of a submitted NDA to ensure the application is sufficiently complete for substantive review. Once the FDA accepts an NDA submission for filing — which occurs, if at all, within 60 days after submission of the NDA — the FDA’s goal for a non-priority review of an NDA is ten months. The review process can be and often is significantly extended, however, by FDA requests for additional information, studies, or clarification. The targeted action date can also be shortened to six

19

months of the 60-day filing date for products that are granted priority review designation because they are intended to treat serious or life-threatening conditions and demonstrate the potential to address unmet medical needs. The FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is cGMP-compliant to assure and preserve the product’s identity, strength, quality, and purity.

After review of an NDA and the facilities where the product candidate is manufactured, the FDA either issues an approval letter or a complete response letter (CRL), outlining the deficiencies in the submission. The CRL may require additional testing or information, including additional pre-clinical or clinical data, for the FDA to reconsider the application. Even if such additional information and data are submitted, the FDA may decide that the NDA still does not meet the standards for approval. Data from clinical trials are not always conclusive and the FDA may interpret data differently than the sponsor. FDA approval of any application

may include many delays or never be granted. If FDA grants approval, an approval letter authorizes commercial marketing of the product candidate with specific prescribing information for specific indications.

Obtaining regulatory approval often takes a number of years, involves the expenditure of substantial resources, and depends on a number of factors, including the severity of the disease in question, the availability of alternative treatments, and the risks and benefits demonstrated in clinical trials. Additionally, as a condition of approval, the FDA may impose restrictions that could affect the commercial success of a drug or require post-approval commitments, including the completion within a specified time period of additional clinical studies, which often are referred to as “Phase 4” or “post-marketing” studies.

Post-approval modifications to the drug, such as changes in indications, labeling, or manufacturing processes or facilities, may require a sponsor to develop additional data or conduct additional pre-clinical studies or clinical trials, to be submitted in a new or supplemental NDA, which would require FDA approval.

Post-Approval Regulation

Once approved, drug products are subject to continuing regulation by the FDA. If ongoing regulatory requirements are not met, or if safety or manufacturing problems occur after the product reaches the market, the FDA may at any time withdraw product approval or take actions that would limit or suspend marketing. Additionally, the FDA may require post-marketing studies or clinical trials, changes to a product’s approved labeling, including the addition of new warnings and contraindications, or the implementation of other risk management measures, including distribution-related restrictions, if there are new safety information developments.

Good Manufacturing Practices. Companies engaged in manufacturing drug products or their components must comply with applicable cGMP requirements and product-specific regulations enforced by the FDA and other regulatory agencies. Compliance with cGMP includes adhering to requirements relating to organization and training of personnel, buildings and facilities, equipment, control of components and drug product containers and closures, production and process controls, quality control and quality assurance, packaging and labeling controls, holding and distribution, laboratory controls, and records and reports. The FDA regulates and inspects equipment, facilities, and processes used in manufacturing pharmaceutical products prior to approval. If, after receiving approval, a company makes a material change in manufacturing equipment, location, or process (all of which are, to some degree, incorporated in the NDA), additional regulatory review and approval may be required. The FDA also conducts regular, periodic visits to re-inspect equipment, facilities, and processes following the initial approval of a product. Failure to comply with applicable cGMP requirements and conditions of product approval may lead the FDA to take enforcement actions or seek sanctions, including fines, issuance of warning letters, civil penalties, injunctions, suspension of manufacturing operations, operating restrictions, withdrawal of FDA approval, seizure or recall of products, and criminal prosecution. Although we periodically monitor the FDA compliance of our third-party manufacturers, we cannot be certain that our present or future third-party manufacturers will consistently comply with cGMP and other applicable FDA regulatory requirements.

In addition to cGMP requirements, drug-device combination products are also subject to certain additional manufacturing and safety reporting regulations for devices. Specifically, the FDA requires that drug-device combination products comply with certain provisions of the Quality System Regulation (QSR), which sets forth the FDA’s manufacturing quality standards for medical devices. In addition to drug safety reporting requirements, the FDA also requires that we comply with some device safety reporting requirements for our drug-device combination product.

20

Advertising and Promotion. The FDA and other federal regulatory agencies closely regulate the marketing and promotion of drugs through, among other things, standards and regulations for direct-to-consumer advertising, advertising and promotion to healthcare professionals, communications regarding unapproved uses, industry-sponsored scientific and educational activities, and promotional activities involving the Internet. A product cannot be promoted before it is approved. After approval, product promotion can include only those claims relating to safety and effectiveness that are consistent with the labeling approved by the FDA. Healthcare providers are permitted to prescribe drugs for “off-label” uses — that is, uses not approved by the FDA and not described in the product’s labeling — because the FDA does not regulate the practice of medicine. However, FDA regulations impose restrictions on manufacturers’ communications regarding off-label uses. Broadly speaking, a manufacturer may not promote a drug for off-label use, but under certain conditions may engage in non-promotional, balanced, scientific communication regarding off-label use. Failure to comply with applicable FDA requirements and restrictions in this area may subject a company to adverse publicity and enforcement action by the FDA, the Department of Justice, or the Office of the Inspector General of the Department of Health and Human Services, as well as state authorities. This could subject a company to a range of penalties that could have a significant commercial impact, including civil and criminal fines and agreements that materially restrict the manner in which a company promotes or distributes a drug.

New Legislation. New legislation is passed periodically in Congress, or at the state level, that could significantly change the statutory provisions governing the approval, manufacturing and marketing of products regulated by the FDA. For example, the Food and Drug Omnibus Reform Act, 2022, enacted on December 29, 2022, confirms further authorities to FDA, such as:

Further, FDA revises its regulations and guidance in light of new legislation in ways that may affect our business or products. It is impossible to predict whether other changes to legislation, regulation, or guidance will be enacted, or what the impact of such changes, if any, may be.

Other Requirements. NDA holders must comply with other regulatory requirements, including submitting annual reports, reporting information about adverse drug experiences, reporting marketing status notifications, and maintaining certain records.

Hatch-Waxman Act

The Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Act, establishes two abbreviated approval pathways for pharmaceutical products that are in some way follow-on versions of already approved products.

Generic Drugs. A generic version of an approved drug is approved by means of an abbreviated NDA, or ANDA, by which the sponsor demonstrates that the proposed product is the same as the approved, brand-name drug, which is referred to as the reference listed drug or RLD.(RLD). Generally, an ANDA must contain data and information showing that the proposed generic product and RLD (i) have the same active ingredient, in the same strength and dosage form, to be delivered via the same route of administration, (ii) are intended for the same uses, and (iii) are bioequivalent. This is instead of independently demonstrating the proposed product’s safety and effectiveness, which are inferred from the fact that the product is the same as the RLD, which the FDA previously found to be safe and effective.

505(b)(2) NDAs. As discussed previously, products may also be submitted for approval via an NDA under section 505(b)(2) of the FD&C Act. Unlike an ANDA, this does not excuse the sponsor from demonstrating the proposed product’s safety and effectiveness. Rather, the sponsor is permitted to rely to some degree on information from investigations that were not conducted by or for the applicant and for which the applicant has not obtained a right of reference and must submit its own product-specific data of safety and effectiveness to an extent necessary because of the differences between the products. An NDA approved under 505(b)(2) may in turn serve as an RLD for subsequent applications from other sponsors.

RLD Patents. In an NDA, a sponsor must identify patents that claim the drug substance or drug product or a method of using the drug. When the drug is approved, those patents are among the information about the product that is listed in the FDA publication, Approved Drug Products with Therapeutic Equivalence Evaluations, which is referred to as the Orange Book. The sponsor of an ANDA or 505(b)(2) application seeking to rely on an approved product as the RLD must make one of several certifications regarding each listed patent. A “Paragraph I” certification is the sponsor’s statement that patent information has not been filed for the RLD. A “Paragraph II” certification is the sponsor’s statement that the RLD’s patents have expired. A “Paragraph III” certification is the sponsor’s statement that it will wait for the patent to expire before obtaining approval for its product. A “Paragraph IV” certification is an assertion that the patent does not block approval of the later product, either because the patent is invalid or unenforceable or because the patent, even if valid, is not infringed by the new product.

Regulatory Exclusivities. The Hatch-Waxman Act provides periods of regulatory exclusivity for products that would serve as RLDs for an ANDA or 505(b)(2) application. If a product is a “new chemical entity,” or NCE — generally meaning that the drug contains no active moiety that has been approved by the FDA in any other NDA submitted under section 505(b) of the FD&C Act — there is a period of five years from the product’s approval during which the FDA may not accept for filing any ANDA or 505(b)(2) application for a drug with the same active moiety. An ANDA or 505(b)(2) application may be submitted after four years, however, if the sponsor of the application makes a Paragraph IV certification.

A product that is not an NCE may qualify for a three-year period of exclusivity if the NDA contains new clinical data (other than bioavailability studies), derived from studies conducted by or for the sponsor, that were necessary for approval. In that instance, the exclusivity period does not preclude filing or review of an ANDA or 505(b)(2) application; rather, the FDA is precluded from granting final approval to the ANDA or 505(b)(2) application until three years after approval of the RLD. Additionally, the exclusivity applies only to the conditions of approval that required submission of the clinical data.

Once the FDA accepts for filing an ANDA or 505(b)(2) application containing a Paragraph IV certification, the applicant must within 20 days provide notice to the RLD NDA holder and patent owner that the application has been submitted and provide the

factual and legal basis for the applicant’s assertion that the patent is invalid or not infringed. If the NDA holder or patent owner files suit against the ANDA or 505(b)(2) applicant for patent infringement within 45 days of receiving the Paragraph IV notice, the FDA is prohibited from approving the ANDA or 505(b)(2) application for a period of 30 months or the resolution of the underlying suit, whichever is earlier. If the RLD has NCE exclusivity and the notice is given and suit filed during the fifth year of exclusivity, the regulatory stay extends to 7.5 years after the RLD approval. The FDA may approve the proposed product before the expiration of the regulatory stay if a court finds the patent invalid or not infringed or if the court shortens the period because the parties have failed to cooperate in expediting the litigation.

Patent Term Restoration. A portion of the patent term lost during product development and FDA review of an NDA is restored if approval of the application is the first permitted commercial marketing of a drug containing the active ingredient. The patent term restoration period is generally one-half the time between the effective date of the IND or the date of patent grant (whichever is later) and the date of submission of the NDA, plus the time between the date of submission of the NDA and the date of FDA approval of the product. The maximum period of restoration is five years, and the patent cannot be extended to more than 14 years from the date of FDA approval of the product. Only one patent claiming each approved product is eligible for restoration and the patent holder must apply for restoration within 60 days of approval. The USPTO,U.S. Patent and Trademark Office (USPTO), in consultation with the FDA, reviews and approves the application for patent term restoration.

European and Other International Government Regulation

In addition to regulations in the U.S., we are subject to a variety of regulations in other jurisdictions governing, among other things, clinical trials and any commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in foreign countries prior to the commencement of clinical trials or marketing of the product in those countries. Some countries outside of the U.S. have a similar process that requires the submission of a clinical trial application, or CTA, much like the IND prior to the commencement of human clinical trials. In the EU, for example, similar to the FDA a CTA must be submitted for authorization to the competent national authority of each EU Member State in which the clinical trial is to be conducted. Furthermore, the applicant may only start a clinical trial at a specific study site after the competent ethics committee, much like the IRB, has issued a favorable opinion. Once the CTA is approved in accordance with the EU Clinical Trials Directive 2001/20/EC or Clinical(Clinical Trials Directive,Directive), and the related national implementing provisions of the relevant individual EU Member States’ requirements, clinical trial development may proceed.

In April 2014, the new Clinical Trials Regulation, (EU) No 536/2014, or Clinical Trials Regulation, was adopted. The Regulation entered into force on January 31, 2022. The Clinical Trials Regulation is directly applicable in all the EU Member States, repealing the current Clinical Trials Directive. The new Clinical Trials Regulation allowed parties to start and conduct a clinical trial in accordance with the Clinical Trials Directive during a transitional period of one year which ended on January 31, 2023. Clinical trials authorized under the Clinical Trials Directive before January 31, 2023, can continue to be conducted under the Clinical Trials Directive until January 31, 2025. An application to transition ongoing trials from the current Clinical Trials Directive to the new Clinical Trials Regulation will need to be submitted and authorized in time before the end of the transitional period.

The new Clinical Trials Regulation is intended to simplify and streamline the approval of clinical trials in the EU. The main characteristics of the regulation include: a streamlined application procedure through a single entry point, the Clinical Trials Information System (CTIS); a single set of documents to be prepared and submitted for the application as well as simplified reporting procedures for clinical trial sponsors; and a harmonized procedure for the assessment of applications for clinical trials, which is divided in two parts. The use of the CTIS became mandatory for new clinical trial applications made in accordance with the Clinical Trials Regulation on January 31, 2023. Clinical trial sponsors can use CTIS to apply for authorization to run a clinical trial in all 27 EU Member States and three of the four European Free Trade Association States, Iceland, Liechtenstein and Norway via a single online application.

To obtain regulatory approval to commercialize a new drug under EU regulatory systems, we must submit a MAA, to the competent regulatory authority. In the EU, marketing authorization for a medicinal product can be obtained through a centralized, mutual recognition, decentralized procedure, or the national procedure of an individual EU Member State. A marketing authorization, irrespective of its route to authorization, may be granted only to an applicant established in the EU.

22

The centralized procedure provides for the grant of a single marketing authorization by the European Commission that is valid for all 27 EU Member States and three of the four European Free Trade Association States, Iceland, Liechtenstein, and Norway. Under the centralized procedure, the Committee for Medicinal Products for Human Use, or the CHMP, established at the EMA is responsible for conducting the initial assessment of a product. The maximum timeframe for the evaluation of an MAA is 210 days. This period excludes clock stops during which additional information or written or oral explanation is to be provided by the applicant in response to questions posed by the CHMP. Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of a major public health interest. A major public health interest defined by three cumulative criteria: (i) the seriousness of the disease (for example, heavy disabling or life-threatening diseases) to be treated, (ii) the absence or insufficiency of

an appropriate alternative therapeutic approach, and (iii) anticipation of high therapeutic benefit. If the CHMP accepts to review a medicinal product as a major public health interest, the time limit of 210 days will be reduced to 150 days. It is, however, possible that the CHMP can revert to the standard time limit for the centralized procedure if it considers that it is no longer appropriate to conduct an accelerated assessment.

Irrespective of the related procedure, at the completion of the review period the CHMP will provide a scientific opinion concerning whether or not a marketing authorization should be granted in relation to a medicinal product. This opinion is based on a review of the quality, safety, and efficacy of the product. Within 15 days of the adoption, the EMA will forward its opinion to the European Commission for its decision. Following the opinion of the EMA, the European Commission makes a final decision to grant a centralized marketing authorization. The centralized procedure is mandatory for certain types of medicinal products, including orphan medicinal products, medicinal products derived from certain biotechnological processes, advanced therapy medicinal products and medicinal products containing a new active substance for the treatment of certain diseases. This route is optional for certain other products, including medicinal products that are of significant therapeutic, scientific or technical innovation, or whose authorization would be in the interest of public or animal health at EU level.

Unlike the centralized authorization procedure, the decentralized marketing authorization procedure requires a separate application to, and leads to separate approval by, the competent authorities of each EU Member State in which the product is to be marketed. This application process is identical to the application that would be submitted to the EMA for authorization through the centralized procedure and must be completed within 210 days, excluding potential clock-stops, during which the applicant can respond to questions. The reference EU Member State prepares a draft assessment and drafts of the related materials. The concerned EU Member States must decide whether to approve the assessment report and related materials. If a concerned EU Member State cannot approve the assessment report and related materials due to concerns relating to a potential serious risk to public health, disputed elements may be referred to the European Commission, whose decision is binding on all EU Member States.

The mutual recognition procedure is similarly based on the acceptance by the competent authorities of the EU Member States of the marketing authorization of a medicinal product by the competent authorities of other EU Member States. The holder of a national marketing authorization may submit an application to the competent authority of an EU Member State requesting that this authority recognize the marketing authorization delivered by the competent authority of another EU Member State.

Marketing authorization holders are subject to comprehensive regulatory oversight by the EMA and the competent authorities of the individual EU Member States both before and after grant of marketing authorization. This includes control of compliance by the entities with EU cGMP rules, which govern quality control of the manufacturing process and require documentation policies and procedures.

For other countries outside of the EU, such as countries in Eastern Europe, Latin America, or Asia, the requirements governing the conduct of clinical trials, product licensing, pricing, and reimbursement vary from country to country. Internationally, clinical trials are generally required to be conducted in accordance with GCP, applicable regulatory requirements of each jurisdiction and the medical ethics principles that have their origin in the Declaration of Helsinki.

Compliance

During all phases of development and in the post-market setting, failure to comply with applicable regulatory requirements may result in administrative or judicial sanctions. These sanctions could include the FDA’s imposition of a clinical hold on trials, refusal to approve pending applications, withdrawal of an approval, warning letters or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, product detention or refusal to permit the import or export of products, injunctions, fines, civil penalties or criminal prosecution. Third country authorities can impose equivalent penalties. Any agency or judicial enforcement action could have a material adverse effect on us.

Other Exclusivities

Pediatric Exclusivity. Section 505A of the FD&C Act provides for six months of additional exclusivity or patent protection if an NDA sponsor submits pediatric data that fairly respond to a Written Request from the FDA for such data. The data do not need to

23

show that the product is effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. If reports of requested pediatric studies are submitted to and accepted by FDA within the statutory time limits, whatever statutory or regulatory periods of exclusivity or Orange Book listed patent protection that cover the drug are extended by six months. This is not a patent term extension, but it effectively extends the regulatory period during which the FDA cannot approve an ANDA or 505(b)(2) application owing to regulatory exclusivity or listed patents. When any product is approved, we will evaluate seeking pediatric exclusivity as appropriate.

In the EU, Regulation No 1901/2006 or the Pediatric Regulation,(Pediatric Regulation), requires that prior to obtaining a marketing authorization in the EU, applicants demonstrate compliance with all measures included in an EMA, approved Pediatric Investigation Plan or PIP.(PIP). This PIP covers all subsets in a pediatric population, unless the EMA has granted either, a product-specific waiver, a class waiver, or a deferral for one or more of the measures included in the PIP. Where all measures provided in the agreed PIP are completed, a six-month extension period of qualifying Supplementary Protection Certificates is granted. Between May 2021 and July 2021, the European Commission organized a public consultation to revise, among others, the Pediatric Regulation, as part of its Pharmaceutical Strategy for Europe. The current intention is for the European Commission to publish a proposal for new Regulation by the end of March 2023. Among the changes expected, an evolutionary and simplified PIP would be introduced, allowing allow the sponsor to amend the document as more evidence is gathered, subject to conditions regarding timing and substance.

Orphan Drug Exclusivity. The Orphan Drug Act provides incentives for the development of drugs intended to treat rare diseases or conditions, which are diseases or conditions affecting less than 200,000 individuals in the U.S., or a disease or condition affecting more than 200,000 individuals in the U.S. but there is no reasonable expectation that the cost of developing and making the drug product would be recovered from sales in the U.S. If a sponsor demonstrates that a drug product qualifies for orphan drug designation, the FDA may grant orphan drug designation to the product for that use. The benefits of orphan drug designation include research and development tax credits and exemption from user fees. A drug that is approved for the orphan drug designated indication generally is granted seven years of orphan drug exclusivity. During that period, the FDA generally may not approve any other application for the same product for the same indication, although there are exceptions, most notably when the later product is shown to be clinically superior to the product with exclusivity. The FDA can revoke a product’s orphan drug exclusivity under certain circumstances, including when the product sponsor is unable to assure the availability of sufficient quantities of the product to meet patient needs. Orphan drug exclusivity does not prevent the FDA from approving a different drug for the same disease or condition, or the same biologic for a different disease or condition.

In the EU, medicinal products: (a) that are used to diagnose, treat or prevent life-threatening or chronically debilitating conditions that affect no more than five in 10,000 people in the EU; or (b) that are used to treat or prevent life-threatening or chronically debilitating conditions and that, for economic reasons, would be unlikely to be developed without incentives; and (c) where no satisfactory method of diagnosis, prevention or treatment of the condition concerned exists, or, if such a method exists, the medicinal product would be of significant benefit to those affected by the condition, may be granted an orphan designation in the EU. The application for orphan designation must be submitted to the EMA’s Committee for Orphan Medicinal Products and approved by the European Commission before an application is made for marketing authorization for the product. Once authorized, orphan medicinal product designation entitles an applicant to financial incentives such as reduction of fees or fee waivers. In addition, orphan medicinal products are entitled to ten years of market exclusivity following authorization. During this ten-year period, with a limited number of exceptions, neither the competent authorities of the EU Member States, the EMA, or the European Commission are permitted to accept applications or grant marketing authorization for other similar medicinal products with the same therapeutic indication. However, marketing authorization may be granted to a similar medicinal product with the same orphan indication during the ten-year period with the consent of the marketing authorization holder for the original orphan medicinal product or if the manufacturer of the original orphan medicinal product is unable to supply sufficient quantities. Marketing authorization may also be granted to a similar medicinal product with the same orphan indication if this latter product is safer, more effective or otherwise clinically superior to the original orphan medicinal product. The period of market exclusivity may, in addition, be reduced to six years if it can be demonstrated on the basis of available evidence that the original orphan medicinal product is sufficiently profitable not to justify maintenance of market exclusivity. AOn April 26, 2023, the European Commission adopted its proposal for the revision of Regulation (EC) No 141/2000 on orphan medicinal products (OMP Regulation) is expected by the end of March 2023.. Among the changes expected,proposed, the proposal would introducedraft OMP Regulation reforms the validity of the orphan designationwhich will expire after seven years, amends the scope of market exclusivity and introduces a new definitionsconcept of significant benefit and (highest)modulated market exclusivity with orphan products addressing high unmet medical needs changes tobenefiting from the longest market exclusivity periods and launch conditionality,of 10 years (with possible additional extensions), as well as a removal ofintroduces, among other changes, the power for the EMA to propose new criteria for orphan pediatric incentive.designations. This proposal is currently being discussed and has not yet been adopted.

Data Exclusivity. In the EU, if a marketing authorization is granted for a medicinal product containing a new active substance, that product benefits from eight years of data exclusivity, during which generic marketing authorization applications referring to the data of that product may not be accepted by the regulatory authorities. The product also benefits from 10 years’ market exclusivity during which generic products, even if authorized, may not be placed on the market. The overall ten-year period will be extended to a maximum of 11 years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. AOn April 26, 2023, the European Commission adopted its proposal for the revision of Regulation (EC) No 726/2004 laying

Among the changes, expected, the proposal would reducereduces the current data exclusivity period to a baseline 6-years. Additional regulatory data protection could be obtained upon conditions, but with a maximum of 8-years data exclusivity. This proposal is currently being discussed and has not yet been adopted.

U.S. Healthcare Reform

The Patient Protection and Affordable Care Act, as amended, which we refer to as the Affordable Care Act or ACA, is a sweeping measure intended to expand healthcare coverage within the U.S., primarily through the imposition of health insurance mandates on employers and individuals, the provision of subsidies to eligible individuals enrolled in plans offered on the health insurance exchanges, and expansion of the Medicaid program. This law substantially changed the way healthcare is financed by both governmental and private insurers and has significantly impacted the pharmaceutical industry. Changes that may affect our business include those governing enrollment in federal healthcare programs, reimbursement changes, benefits for patients within a coverage gap in the Medicare Part D prescription drug program (commonly known as the donut hole), rules regarding prescription drug benefits under the health insurance exchanges, changes to the Medicaid Drug Rebate program, expansion of the Public Health Service Act’s 340B drug pricing discount program, or 340B program, fraud and abuse, and enforcement. The Affordable Care Act also requires pharmaceutical manufacturers of branded prescription drugs to pay a branded prescription drug fee to the federal government. Each such manufacturer pays a prorated share of the branded prescription drug fee of $2.8 billion in 2019 and thereafter, based on the dollar value of its branded prescription drug sales to certain federal programs identified in the law. These changes have impacted and will continue to impact existing government healthcare programs and have resulted in the development of new programs, including Medicare payment for performance initiatives.

Some states have elected not to expand their Medicaid programs to individuals with an income of up to 133% of the federal poverty level, as is permitted under the Affordable Care Act. For each state that does not choose to expand its Medicaid program, there may be fewer insured patients overall, which could impact our sales of products and product candidates for which we receive regulatory approval, and our business and financial condition. Where new patients receive insurance coverage under any of the new Medicaid options made available through the Affordable Care Act, the possibility exists that manufacturers may be required to pay Medicaid rebates on drugs used under these circumstances, a decision that could impact manufacturer revenues.

Certain provisions of the Affordable Care Act have been subject to judicial challenges as well as efforts to modify them or to alter their interpretation and implementation. For example, Congress eliminated, starting January 1, 2019, the tax penalty for not complying with the Affordable Care Act’s individual mandate to carry health insurance. Further, the Bipartisan Budget Act of 2018, among other things, amended the Medicare statute to reduce the coverage gap in most Medicare drugs plans, commonly known as the “donut hole,” by raising the required manufacturer point-of-sale discount from 50% to 70% off the negotiated priceprice. The Inflation Reduction Act of 2022 (IRA) sunsets the existing coverage gap program and replaces it with a new manufacturer discount program effective as of January 1, 2019.2025. Additional legislative changes, regulatory changes, and judicial challenges related to the Affordable Care Act remain possible, but the nature and extent of such potential changes or challenges are uncertain at this time. It is unclear how the Affordable Care Act and its implementation, as well as efforts to modify or invalidate the Affordable Care Act, or portions thereof, or its implementation, will affect our business, financial condition, and results of operations. It is possible that the Affordable Care Act, as currently enacted or as it may be amended in the future, and other healthcare reform measures, including those that may be adopted in the future, could have a material adverse effect on our industry generally and on our ability to maintain or increase sales of our products or product candidates for which we receive regulatory approval or to successfully commercialize our products and product candidates.

Other legislative changes relating to reimbursement have been adopted in the U.S. since the Affordable Care Act was enacted. For example, on August 2, 2011, the Budget Control Act of 2011, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congress proposals for spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction, which triggered the legislation’s automatic reductions. In concert with subsequent legislation, this has resulted in aggregate reductions to Medicare payments to providers of, on average, 2% per fiscal year through 2031. Sequestration is currently set at 2% and will increase to 2.25% for the first half of fiscal year 2030, to 3% for the second half of fiscal year 2030, and to 4% for the remainder of the sequestration period that lasts through the first six months of fiscal year 2031. As long as these cuts remain in effect, they could adversely impact payment for any products we may commercialize in the future. We expect that additional federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, and in turn could significantly reduce the projected value of certain development projects and reduce our profitability.

Additional legislative changes, regulatory changes, or guidance could be adopted, which may impact the marketing approvals and reimbursement for our product candidates. For example, there has been increasing legislative, regulatory, and enforcement interest in the United States with respect to drug pricing practices. There have been several Congressional inquiries and proposed and enacted federal and state legislation and regulatory initiatives designed to, among other things, bring more transparency to product pricing, evaluate the relationship between pricing and manufacturer patient programs, and reform government healthcare program reimbursement methodologies for drug products. If healthcare policies intended to curb healthcare costs are adopted or if we experience negative publicity with respect to pricing of our products or the pricing of pharmaceutical drugs generally, the prices that we charge for any approved products may be limited, our commercial opportunity may be limited, and/or our revenues from sales of our products may be negatively impacted.

On August 12, 2022, the Inflation Reduction Act of 2022 (IRA) was signed into law. The IRA includes several drug pricing policies that are intended to reduce costs for the Medicare program and its beneficiaries, as well as a variety of provisions on the environment and clean energy, corporate taxes, and other health care policies. The IRA contains a negotiation provision that requires the Secretary of Health and Human Services to negotiate, with respect to Medicare units and subject to a specified cap, the price of a set number of high Medicare spend drugs and biologicals per year starting in 2026. The IRA limits the negotiation eligibility for the 2026, 2027, and 2028 program years and afford limited additional relief for “small biotech drugs” of certain small manufacturers which, among other things, represent a limited portion (as specified in the text) of Medicare program spending. The IRA also penalizes manufacturers of certain Medicare Part B and D drugs for price increases above inflation and makes several changes to the Medicare Part D benefit, including a limit on annual out-of-pocket costs, and a change in manufacturer liability under the program.

Coverage and Reimbursement

Sales of any of our products and product candidates, if approved and once commercialized, depend, in part, on the extent to which the costs of the productsproduct will be covered by Medicare and Medicaid, and private payors, such as commercial health insurers and managed care organizations. Third-party payors determine which drugs they will cover and the amount of reimbursement they will provide for a covered drug. In the U.S., there is no uniform system among payors for making coverage and reimbursement decisions. In addition, 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 once coverage is approved. Payors may limit coverage to specific products on an approved list, or formulary, which might not include all of the FDA-approved products for a particular indication.

In order to secure coverage and reimbursement for our products, we may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costly studies required to obtain FDA or other comparable regulatory approvals. Even if we conduct pharmacoeconomic studies, our product candidatesproducts may not be considered medically necessary or cost-effective by payors. Further, a payor’s decision to provide coverage for a product does not implyguarantee that an adequate reimbursement rate will be approvedset, including because HCPshealth care providers (HCPs) negotiate their own reimbursement directly with commercial payors.

In the past, payors have implemented reimbursement metrics and periodically revised those metrics as well as the methodologies used as the basis for reimbursement rates, such as ASP, average manufacturer price, or AMP, and actual acquisition cost. The existing data for reimbursement based on these metrics is relatively limited, although certain states have begun to survey acquisition cost data for the purpose of setting Medicaid reimbursement rates. CMS surveys and publishes retail pharmacy acquisition cost information in the form of National Average Drug Acquisition Cost files to provide state Medicaid agencies with a basis of comparison for their own reimbursement and pricing methodologies and rates.

We have participated in and, if we obtain approval to commercialize additional products, we expect to participate in, and have certain price reporting obligations to, the Medicaid Drug Rebate Program. This program requires us to pay a rebate for each unit of drug reimbursed by Medicaid. The amount of the “basic” portion of the rebate for each product is set by law as the larger of: (i) 23.1% of quarterly AMP, or (ii) the difference between quarterly AMP and the quarterly best price available from us to any commercial or non-governmental customer, or Best Price. AMP must be reported on a monthly and quarterly basis and Best Price is reported on a quarterly basis only. In addition, the rebate also includes the “additional” portion, which adjusts the overall rebate amount upward as an “inflation penalty” when the drug’s latest quarter’s AMP exceeds the drug’s AMP from the first full quarter of sales after launch, adjusted for increases in the Consumer Price Index-Urban. The upward adjustment in the rebate amount per unit is equal to the excess amount of the current AMP over the inflation-adjusted AMP from the first full quarter of sales. Rebates under the Medicaid Drug Rebate Program are currently capped at 100 percentno longer subject to a cap as of AMP, but that cap is set to be removed, effective January 1, 2024, which could increase our rebate liability. The rebate amount is computed each quarter based on our report to CMS of current quarterly AMP and Best Price for our drug. We are required to report revisions to AMP or Best Price within a period not to exceed 12 quarters from the quarter in which the data was originally due. Any such revisions could have the impact of increasing or decreasing our rebate liability for prior quarters, depending on the direction of the revision. The Affordable Care Act made significant changes to the Medicaid Drug Rebate Program, and CMS issued a final regulation which became effective on April 1, 2016, to implement the changes to the Medicaid Drug Rebate program under the Affordable Care Act. On December 21, 2020, CMS issued aanother final regulation that modified existing Medicaid Drug Rebate Program regulations to permit reporting multiple Best Price figures with regard to value based purchasing arrangements (beginning in 2022) and provided definitions for “line extension,” “new formulation,” and related terms with the practical effect of expanding the scope of drugs considered to be line extensions (beginning in 2022). While the regulatory provisions that purported to affect the availability of the AMP and Best Price exclusions of manufacturer-sponsored patient benefit programs in the context of pharmacy benefit manager “accumulator” programs were invalidated by a court, accumulator, and other such programs may continue to negatively affect us in other ways.

Federal law requires that any manufacturer that participates in the Medicaid Drug Rebate Program also participate in the Public Health Service’s 340B drug pricing program in order for federal funds to be available for the manufacturer’s drugs under Medicaid and Medicare Part B. The 340B program, which is administered by the Health Resources and Services Administration, or HRSA, requires participating manufacturers to agree to charge statutorily defined covered entities no more than the 340B “ceiling price” for

the manufacturer’s covered outpatient drugs. These 340B covered entities include a variety of community health clinics and other entities that receive health services grants from the Public Health Service, as well as hospitals that serve a disproportionate share of low-income patients. The 340B ceiling price is calculated using a statutory formula, which is based on the AMP and rebate amount for the covered outpatient drug as calculated under the Medicaid Drug Rebate Program. Any changes to the definition of AMP and the Medicaid rebate amount under the Affordable Care Act or other legislation could affect our 340B ceiling price calculations and negatively impact our results of operations.

HRSA issued a final regulation regarding the calculation of the 340B ceiling price and the imposition of civil monetary penalties on manufacturers that knowingly and intentionally overcharge covered entities, which became effective on January 1, 2019. It is currently unclear how HRSA will apply its enforcement authority under this regulation. HRSA has also implemented a ceiling price reporting requirement related to the 340B program under which we are required to report 340B ceiling prices to HRSA on a quarterly basis, and HRSA then publishes that information to covered entities. Moreover, under a final regulation effective January 13, 2021, HRSA newly established an administrative dispute resolution (ADR), process for claims by covered entities that a manufacturer has engaged in overcharging, and by manufacturers that a covered entity violated the prohibitions against diversion or duplicate discounts. Such claims are to be resolved through an ADR panel of government officials rendering a decision that couldmay be appealed only into federal court. An ADR proceeding could subject us to onerous procedural requirements and could result in additional liability. In addition, legislation may be introduced that, if passed, would further expand the 340B program to additional covered entities or would require participating manufacturers to agree to provide 340B discounted pricing on drugs used in an inpatient setting.

Federal law also requires that a company that participates in the Medicaid Drug Rebate program report ASP information each quarter to CMS for certain categories of drugs that are paid under the Medicare Part B program. For calendar quarters beginning January 1, 2022, manufacturers are required to report the average sales price for certain drugs under the Medicare program regardless of whether they participate in the Medicaid Drug Rebate Program. Manufacturers calculate the ASP based on a statutorily defined formula as well as regulations and interpretations of the statute by CMS. CMS usesmay use these submissions to determine payment rates for drugs under Medicare Part B. Starting in 2023, manufacturers must pay refunds to Medicare for single source drugs or biologicals, or biosimilar biological products, reimbursed under Medicare Part B and packaged in single-dose containers or single-use packages, for units of discarded drug reimbursed by Medicare Part B in excess of 10 percent of total allowed charges under Medicare Part B for that drug. Manufacturers that fail to pay refunds could be subject to civil monetary penalties of 125 percent of the refund amount. For more information about Medicare Part B, refer to the risk factor entitled “Our products and product candidates, if approved and commercialized, may become subject to unfavorable pricing regulations, third-party reimbursement practices, or healthcare reform initiatives which could harm our business” set forth under the section titled “Risk Factors” in this Annual Report on Form 10-K.

Statutory or regulatory changes or CMS guidance could affect the pricing of our approved products, and could negatively affect our results of operations. On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022, orThe IRA, which, among other things, requires the Secretary of Health and Human Services Secretary to negotiate, with respect to Medicare units and subject to a specified cap, the price of a set number of certain high Medicare spend drugs and biologicals per year starting in 2026. Starting January 2023, theThe IRA establishesestablished a Medicare Part B inflation rebate scheme, under which, generally speaking, manufacturers will owe rebates if the average sales price of a Part B drug increases faster than the pace of inflation. Failure to timely pay a Part B inflation rebate is subject to a civil monetary penalty. These or any other public policy changes could impact the market conditions for our products. We further expect continued scrutiny on government price reporting and pricing more generally from Congress, agencies, and other bodies. For more information about Medicare Part B, refer to the risk factor entitled “Our products and product candidates, if approved and commercialized, may become subject to unfavorable pricing regulations, third-party reimbursement practices, or healthcare reform initiatives which could harm our business” set forth under the section titled “Risk Factors” in this Annual Report on Form 10-K. In the U.S. Medicare program, outpatient prescription drugs may be covered under Medicare Part D. Medicare Part D is a voluntary prescription drug benefit, through which Medicare beneficiaries may enroll in prescription drug plans offered by private entities for coverage of outpatient prescription drugs. Part D plans include both stand-alone prescription drug benefit plans and prescription drug coverage as a supplement to Medicare Advantage plans provided for under Medicare Part C.

Coverage and reimbursement for covered outpatient drugs under Part D are not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Although Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, they have some flexibility to establish those categories and classes and are not required to cover all of the drugs in each category or class. Medicare Part D prescription drug plans may use formularies to limit the number of drugs that will be covered in any therapeutic class and/or impose differential cost sharing or other utilization management techniques.

Medicare Part D coverage is available for our products and may be available for any future product candidates for which we receive marketing approval.approval and commercialize. However, in order for the products that we market to be included on the formularies of Part D prescription drug plans, we likely will have to offer pricing that is lower than the prices we might otherwise obtain. Changes to Medicare Part D that give plans more freedom to limit coverage or manage utilization, and other cost reduction initiatives in the program, could decrease the coverage and price that we receive for any approved products and could seriously harm our business.

In addition, manufacturers are currently required to provide to CMS a 70% discount on brand name prescription drugs utilized by Medicare Part D beneficiaries when those beneficiaries are in the coverage gap phase of the Part D benefit design. The IRA sunsets the coverage gap discount program starting in 2025 and replaces it with a new manufacturer discount program and makes other reforms to the Part D benefit, which could increase our liability under Part D. Further, starting October 2022, the IRA establishes a Medicare Part D inflation rebate scheme, under which, generally speaking, manufacturers will owe additional rebates if the AMP of a Part D drug increases faster than the pace of inflation. Failure to timely pay a Part D inflation rebate is subject to a civil monetary penalty.

In order to be eligible to have our products paid for with federal funds under the Medicaid and Medicare Part B programs and purchased by certain federal agencies and grantees, we must participate in the U.S. Department of Veterans Affairs, (VA), Federal Supply Schedule, (FSS), pricing program. Under this program, we are obligated to make our “innovator” drugs available for procurement on an FSS contract and charge a price to four federal agencies — the VA, U.S. Department of Defense, (DoD), Public Health Service and U.S. Coast Guard — that is no higher than the statutory Federal Ceiling Price, (FCP). The FCP is based on the non-federal average manufacturer price, (Non-FAMP), which we calculate and report to the VA on a quarterly and annual basis. We also may participate in the Tricare Retail Pharmacy program, under which we would pay quarterly rebates on utilization of innovator products that are dispensed through the Tricare Retail Pharmacy network to Tricare beneficiaries. The rebates are calculated as the difference between the annual Non-FAMP and FCP.

Pricing and rebate calculations vary across products and programs, are complex, and are often subject to interpretation by us, governmental or regulatory agencies, and the courts. We could be held liable for errors associated with our submission of pricing data. In addition to retroactive Medicaid rebates and the potential for issuing 340B program refunds, if we are found to have knowingly submitted false AMP, Best Price, or Non-FAMP information to the government, we may be liable for significant civil monetary penalties per item of false information. If we are found to have made a misrepresentation in the reporting of our ASP, the Medicare statute provides for significant civil monetary penalties for each misrepresentation for each day in which the misrepresentation was applied. Our failure to submit monthly/quarterly AMP and Best Price data on a timely basis could result in a significant civil monetary penalty per day for each day the information is late beyond the due date. Such conduct also could be grounds for CMS to terminate our Medicaid drug rebate agreement, in which case federal payments may not be available under Medicaid or Medicare Part B for our covered outpatient drugs. Significant civil monetary penalties also could apply to late submissions of Non-FAMP information. Civil monetary penalties could also be applied if we are found to have charged 340B covered entities more than the statutorily mandated ceiling price or HRSA could terminate our agreement to participate in the 340B program, in which case federal payments may not be available under Medicaid or Medicare Part B for our covered outpatient drugs. In addition, claims submitted to federally-funded healthcare programs, such as Medicare and Medicaid, for drugs priced based on incorrect pricing data provided by a manufacturer can implicate the federal civil False Claims Act. Civil monetary penalties could be due if we fail to offer discounts to beneficiaries under the Medicare Part D coverage gap discount program. Furthermore, under the refund program for discarded drugs, manufacturers that fail to pay refunds could be subject to civil monetary penalties of 125 percent of the refund amount.

The containment of healthcare costs has become a priority of federal, state and foreign governments, and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures, and foreign governments have shown significant interest in implementing cost-containment programs to limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement, and requirements for substitution of generic products for branded prescription drugs. For example, there have been several recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs, and reform government program reimbursement methodologies for drug products.

Beginning April 1, 2013, Medicare payments for all items and services, including drugs, were reduced by 2% under the sequestration (i.e., automatic spending reductions) required by the Budget Control Act of 2011, as amended by the American Taxpayer Relief Act of 2012. Subsequent legislation extended the 2% reduction, generally to 2031 Sequestration is currently set at 2% and will increase to 2.25% for the first half of fiscal year 2030, to 3% for the second half of fiscal year 2030, and to 4% for the remainder of the sequestration period that lasts through the first six months of fiscal year 2031. As long as these cuts remain in effect, they could adversely impact payment for any products we now sell or may commercialize in the future. If Congress does not take action in the future to modify these sequestrations, Medicare Part D plans could seek to reduce their negotiated prices for drugs. Other legislative or regulatory cost containment legislation could have a similar effect.

Further, the Affordable Care Act may reduce the profitability of drug products. It expanded manufacturers’ rebate liability under the Medicaid program from fee-for-service Medicaid utilization to include the utilization of Medicaid managed care organizations as well, and increased the minimum Medicaid rebate due for most innovator drugs. The Affordable Care Act and subsequent legislation also changed the definition of AMP. On February 1, 2016, CMS issued final regulations to implement the changes to the Medicaid drug rebate program under the Affordable Care Act. These regulations became effective on April 1, 2016.

28

The Affordable Care Act requires pharmaceutical manufacturers of branded prescription drugs to pay a branded prescription drug fee to the federal government. Each such manufacturer pays a prorated share of the branded prescription drug fee of $2.8 billion in 2019 and thereafter, based on the dollar value of its branded prescription drug sales to certain federal programs identified in the law. The Affordable Care Act also expanded the Public Health Service Act’s 340B program to include additional types of covered entities. Substantial new provisions affecting compliance have also been enacted, which may affect our business practices with healthcare practitioners. It appears likely that the Affordable Care Act will continue the pressure on pharmaceutical pricing, especially under the Medicare and Medicaid programs, and may also increase our regulatory burdens and operating costs.

Additional legislative changes, regulatory changes, and judicial challenges related to the Affordable Care Act remain possible, as discussed above under the heading “U.S. Healthcare Reform.” In addition, thereThere likely will continue to be proposals by legislators at both the federal and state levels, regulators, and third-party payors to contain healthcare costs. Thus, even if we obtain favorable coverage and reimbursement status for our products and any product candidates for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Different pricing and reimbursement schemes exist in other countries. In the EU, each EU Member State can restrict the range of medicinal products for which its national health insurance system provides reimbursement and can control the prices of medicinal products for human use marketed on its territory. As a result, following receipt of marketing authorization in an EU Member State, through any application route, the applicant is required to engage in pricing discussions and negotiations with the competent pricing authority in the individual EU Member State. The governments of the EU Member States influence the price of pharmaceutical products through their pricing and reimbursement rules and control of national healthcare systems that fund a large part of the cost of

those products to consumers. Some EU Member States operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed upon. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. Other EU Member States allow companies to fix their own prices for medicines but monitor and control company profits. Others adopt a system of reference pricing, basing the price or reimbursement level in their territories either on the pricing and reimbursement levels in other countries or on the pricing and reimbursement levels of medicinal products intended for the same therapeutic indication. Further, some EU Member States approve a specific price for the medicinal product or may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal on the market. The downward pressure on healthcare costs in general, particularly prescription drugs, has become more intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, we may face competition for our product candidates from lower-priced products in foreign countries that have placed price controls on pharmaceutical products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country.

Health Technology Assessment, or HTA, of medicinal products, however, is becoming an increasingly common part of the pricing and reimbursement procedures in some EU Member States. These EU Member States include France, Germany, Ireland, Italy, and Sweden. HTA is the procedure according to which the assessment of the public health impact, therapeutic impact and the economic and societal impact of use of a given medicinal product in the national healthcare systems of the individual country is conducted. HTA generally focuses on the clinical efficacy and effectiveness, safety, cost, and cost-effectiveness of individual medicinal products as well as their potential implications for the healthcare system. Those elements of medicinal products are compared with other treatment options available on the market.

The outcome of HTA regarding specific medicinal products will often influence the pricing and reimbursement status granted to these medicinal products by the competent authorities of individual EU Member States. The extent to which pricing and reimbursement decisions are influenced by the HTA of the specific medicinal product varies between EU Member States.

In addition, pursuant to Directive 2011/24/EU on the application of patients’ rights in cross-border healthcare, a voluntary network of national authorities or bodies responsible for HTA in the individual EU Member States was established. The purpose of the network is to facilitate and support the exchange of scientific information concerning HTAs. This may lead to harmonization of the criteria taken into account in the conduct of HTAs between EU Member States and in pricing and reimbursement decisions and may negatively affect price in at least some EU Member States.

On January 31, 2018, the European Commission adopted a proposal for an HTA Regulation intended to set out an EU-wide framework for HTA and boost cooperation among EU Member States in assessing health technologies, including new medicinal products. The HTA Regulation provides the basis for permanent and sustainable cooperation at the EU level for joint clinical assessments in these areas and is therefore complementary to Directive 2011/24/EU. The HTA Regulation was finally adopted on December 13, 2021, and entered into force on January 11, 2022. The HTA Regulation will apply to all EU Member States from January 12, 2025.

29

The HTA Regulation provides that EU Member States will be able to use common HTA tools, methodologies, and procedures across the EU. Individual EU Member States will continue to be responsible for drawing conclusions on the overall value of a new health technology for their healthcare system, and pricing and reimbursement decisions.

Healthcare Fraud and Abuse Laws

In addition to FDA restrictions on marketing of pharmaceutical products, if and when we commercialize our business isproduct candidates, our relationship with customers and third party payors will be subject to healthcareapplicable anti-kickback, fraud and abuse, regulation and enforcement by both the federal governmentother laws and the states in which we conduct our business.regulations. These laws include, but are not limited to the following:

The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration, directly or indirectly, in cash or in kind, to induce or in return for purchasing, leasing, ordering or arranging for or recommending the purchase, lease or order of any healthcare item or service reimbursable, in whole or in part, under Medicare, Medicaid or other federally financed healthcare programs. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. A violation of the Anti-Kickback Statute may be established without proving actual knowledge of the statute or specific intent to violate it. The government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act. Although there are a number of statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution, the exceptions and safe harbors are drawn narrowly and practices that involve remuneration to those who prescribe, purchase, or recommend pharmaceuticals, including certain discounts, or engaging such individuals as consultants, speakers or advisors, may be subject to scrutiny if they do not fit squarely within the exception or safe harbor. For example, in November 2020, the OIG issued a Special Fraud Alert to highlight certain inherent fraud and abuse risks associated with speaker fees, honorariums and expenses paid by pharmaceutical and medical device companies to healthcare professionals participating in company-sponsored events. The Special Fraud Alert sent a clear signal that speaker programs will be subject to potentially heightened enforcement scrutiny. Our practices may not in all cases meet all of the criteria for safe harbor protection from anti-kickback liability. Moreover, there are no safe harbors for many common practices, such as educational and research grants, charitable donations, product support and patient assistance programs. Arrangements that implicate the Anti-Kickback Statute and do not fit within an exception or safe harbor are reviewed on a case-by-case basis to determine whether, based on the facts and circumstances, they violate the statute.

The federal civil False Claims Act prohibits any person from, among other things, knowingly presenting, or causing to be presented, a false or fraudulent claim for payment of government funds, or knowingly making, using, or causing to be made or used, a false record or statement material to an obligation to pay money to the government or knowingly concealing or knowingly and

improperly avoiding, decreasing, or concealing an obligation to pay money to the federal government. Actions under the False Claims Act may be brought by private individuals known as qui tam relators in the name of the government and to share in any monetary recovery. In recent years, several pharmaceutical and other healthcare companies have faced enforcement actions under the False Claims Act for, among other things, providing free product to customers with the expectation that the customers would bill federal programs for the product, and other interactions with prescribers and other customers including interactions that may have affected customers’ billing or coding practices on claims submitted to the federal government. Other companies have faced enforcement actions for causing false claims to be submitted because of the company’s marketing the product for unapproved, and thus non-reimbursable, uses. Federal enforcement agencies also have shown increased interest in pharmaceutical companies’ product and patient assistance programs, including reimbursement and co-pay support services, and a number of investigations into these programs have resulted in significant civil and criminal settlements.

The Health Insurance Portability and Accountability Act of 1996 and its implementing regulations (collectively HIPAA) prohibits, among other things, knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private third-party payors. HIPAA also prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement or representation, or making or using any false writing or document knowing the same to contain any materially false, fictitious or fraudulent statement or entry in connection with the delivery of or payment for healthcare benefits, items or services. We may obtain health information from third parties that are subject to privacy and security requirements under HIPAA and we could potentially be subject to criminal penalties if we, our affiliates, or our agents knowingly obtain or disclose individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA.

The majority of states also have statutes or regulations similar to the federal anti-kickback and false claims laws, which apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor. Several states now require pharmaceutical companies to report expenses relating to the marketing and promotion of pharmaceutical products in those states and to report gifts and payments to individual health care providersHCPs in those states. Some of these states also prohibit certain marketing-related activities including the provision of gifts, meals, or other items to certain health care providers.HCPs. Other states have laws requiring pharmaceutical sales representatives to be registered or licensed, and still others impose limits on co-pay

30

assistance that pharmaceutical companies can offer to patients. In addition, several states require pharmaceutical companies to implement compliance programs or marketing codes.

The Physician Payments Sunshine Act, implemented as the Open Payments program, and its implementing regulations, requires manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to CMS information related to direct or indirect payments and other transfers of value to physicians, physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, certified nurse-midwives, and teaching hospitals, as well as ownership and investment interests held in the company by physicians and their immediate family members. AsMany of last year, manufacturers mustthe non-U.S. jurisdictions where we operate also have equivalent laws requiring us to report transfers of value made to physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, and certified nurse-midwives.healthcare professionals.

Compliance with such laws and regulations will require substantial resources. Because of the breadth of these various fraud and abuse laws, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Such a challenge could have material adverse effects on our business, financial condition and results of operations. In the event governmental authorities conclude that our business practices do not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations, they may impose sanctions under these laws, which are potentially significant and may include civil monetary penalties, damages, exclusion of an entity or individual from participation in government health care programs, criminal fines and imprisonment, additional reporting requirements if we become subject to a corporate integrity agreement or other settlement to resolve allegations of violations of these laws, as well as the potential curtailment or restructuring of our operations. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity.

Healthcare Privacy Laws

We may be subject to federal, state, and foreign laws and regulations governing data privacy and security of health information, and the collection, use, disclosure, and protection of health-related and other personal information, including state data breach notification laws, state health information and/or genetic privacy laws, and federal and state consumer protection laws, such as Section 5 of the FTC Act, many of which differ from each other in significant ways, thus complicating compliance efforts. Compliance with these laws is difficult, constantly evolving, and time consuming. Many of these state laws enable a state attorney general to bring actions and provide private rights of action to consumers as enforcement mechanisms. There is also heightened sensitivity around certain types of health information, such as sensitive condition information or the health information of minors, which may be subject to additional protections. Federal regulators, state attorneys general, and plaintiffs’ attorneys, including class action attorneys, have been and will likely continue to be active in this space.

The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues which may affect our business. Failure to comply with these laws and regulations could result in government enforcement actions and create liability for us (including the imposition of significant civil and/or criminal penalties), private litigation and/or adverse publicity that could negatively affect our business. We may obtain health information from third parties, such as health care providersHCPs who prescribe our products, and research institutions we collaborate with, who are subject to privacy and security requirements under HIPAA. Although we are not directly subject to HIPAA, other than potentially with respect to providing

certain employee benefits, we could be subject to criminal penalties if we or our affiliates or agents knowingly obtain individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA.

In California, the California Consumer Privacy Act (CCPA) establishes certain requirements for data use and sharing transparency and provides California consumers (as defined in the law) certain rights concerning the use, disclosure, and retention of their personal data. In November 2020, California voters approved the California Privacy Rights Act (CPRA) ballot initiative which introduced significant amendments to the CCPA and established and funded a dedicated California privacy regulator, the California Privacy Protection Agency (CPPA). The amendments introduced by the CPRA went effect on January 1, 2023, and new implementing regulations are expectedcontinue to be introduced by the CPPA. Failure to comply with the CCPA may result in, among other things, significant civil penalties and injunctive relief, or statutory or actual damages. In addition, California residents have the right to bring a private right of action in connection with certain types of incidents. These claims may result in significant liability and damages. Similarly, there are a number of legislative proposals in the EU, the United States, at both the federal and state level, as well as other jurisdictions that could impose new obligations or limitations in areas affecting our business. For example, other states, including Virginia, Colorado, Utah, Indiana, Iowa, Tennessee, Montana, Texas, and Connecticut have enacted privacy laws similar to the CCPA that impose new obligations or limitations in areas affecting our business and we continue to assess the impact of these state legislation, on our business as additional information and guidance becomes available. In addition, some countries are considering or have passed legislation implementing data protection requirements or requiring local storage and processing of data or similar requirements that could increase the cost and complexity of delivering our services and research activities. These laws and regulations are evolving and subject to interpretation, and may impose limitations on our activities or otherwise adversely affect our business. The obligations to comply with the CCPA and evolving legislation may require us, among other things, to update our notices and develop new processes internally and with our partners. In

31

addition, we could be subject to regulatory actions and/or claims made by individuals and groups in private litigation involving privacy issues related to data collection and use practices and other data privacy laws and regulations, including claims for misuse or inappropriate disclosure of data, as well as unfair or deceptive acts or practices in violation of Section 5(a) of the Federal Trade Commission Act (FTC Act). The FTC expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered sensitive data that merits stronger safeguards. With respect to privacy, the FTC also sets expectations that companies honor the privacy promises made to individuals about how the company handles consumers’ personal information; any failure to honor promises, such as the statements made in a privacy policy or on a website, may also constitute unfair or deceptive acts or practices in violation of the FTC Act. While we do not intend to engage in unfair or deceptive acts or practices, the FTC has the power to enforce promises as it interprets them, and events that we cannot fully control, such as data breaches, may be result in FTC enforcement. Enforcement by the FTC under the FTC Act can result in civil penalties or decades-long enforcement actions. These laws and regulations, as well as any associated claims, inquiries, or investigations or any other government actions may lead to unfavorable outcomes including increased compliance costs, delays or impediments in the development of new products, negative publicity, increased operating costs, diversion of management time and attention, and remedies that harm our business, including fines or demands or orders that we modify or cease existing business practices.

Outside the U.S., the legislative and regulatory landscape for privacy and data security continues to evolve. There has been increased attention to privacy and data security issues that could potentially affect our business, including the EU General Data Protection Regulation including as implemented in the UK (collectively, GDPR), which imposes penalties for the most serious breaches of up to EUR 20 million or 4% of a noncompliant company’s annual global revenue, whichever is greater. The GDPR regulates the processing of personal data (including health data from clinical trials) and places certain obligations on the processing of such personal data including ensuring the lawfulness of processing personal data (including obtaining valid consent of the individuals to whom the personal data relates, where applicable), the processing details disclosed to the individuals, the adequacy, relevance and necessity of the personal data collected, the retention of personal data collected, the sharing of personal data with third parties, the transfer of personal data out of the European Economic Area/UK to third countries including the U.S., contracting requirements (such as with clinical trial sites and vendors), the use of personal data in accordance with individual rights, the security of personal data and security breach/incident notifications. Data protection authorities from the different European Member States and the UK may interpret the GDPR and applicable related national laws differently and impose requirements additional to those provided in the GDPR and that sit alongside the GDPR, as set out under applicable local data protection law. In addition, guidance on implementation and compliance practices may be issued, updated or otherwise revised. Enforcement by European and UK regulators is generally active, and failure to comply with the GDPR or applicable Member State/UK local law may result in fines, amongst other things (such as notices requiring compliance within a certain timeframe). Further, the UK Government may amend/update UK data protection law, which may result in changes to our business operations and potentially incur commercial cost.

European/UK data protection laws, including the GDPR, generally restrict the transfer of personal data from the European Economic Area (EEA), including the EU, United Kingdom and Switzerland, to the U.S. and most other countries (except those deemed to be adequate by the European Commission/UK Secretary of State as applicable) unless the parties to the transfer have implemented specific safeguards to protect the transferred personal data. While previously U.S. companies could rely on self-certification to the EU-U.S. and Swiss-U.S. Privacy Shield frameworks administered by the U.S. Department of Commerce as one of these safeguards to legitimize transfers from the EU and Switzerland to the U.S., this has been invalidated by the Court of Justice of the European Union (CJEU). The CJEU found that the Standard Contractual Clauses (SCCs), one of the primary safeguards for legitimizing data transfers, were valid in principle, but placed obligations on the parties entering into them including to verify whether an adequate level of protection is provided in the recipient jurisdiction, and whether additional measures are required to bring the level of protection in line with EU standards. Following this decision, the European Data Protection Board issued guidance on how organizations should approach international data transfers of GDPR-covered personal data, including the supplemental measures companies can adopt to help protect against overarching surveillance outside of the EU. In June 2021,On July 10, 2023, the European Commission adopted a new set of SCCs aimed at enabling lawful transfers ofits

adequacy decision for the EU-U.S. Data Privacy Framework, meaning that personal data can now flow freely from the E.U. to non-adequate countries outsideU.S. companies that participate in the EEA, the deadline for the adoption of which was December 27 2022.Data Privacy Framework. There are also recent developments regarding data transfers in the UK, which formally approved two mechanisms for transferring UK data overseas and that came into force on March 21, 2022: the International Data Transfer Agreement or the International Data Transfer Addendum to the SCCs. The UK Information Commissioner’s Office also issued guidance on how to approach undertaking risk assessments for transfers of UK data to non-adequate countries outside the UK.

A lack of valid transfer mechanisms for GDPR-covered data could increase exposure to enforcement actions as described above, and may affect our business operations and require commercial cost (including potentially limiting our ability to collaborate/work with certain third parties and/or requiring an increase in our data processing capabilities in the EU/UK). Further, the European/UK data protection laws (including laws on data transfers as set out above) may also be updated/revised, accompanied by new guidance and/or judicial/regulatory interpretations, which could entail further impacts on our compliance efforts and increased cost.

Foreign Corrupt Practices Act

In addition, the U.S. Foreign Corrupt Practices Act of 1977, as amended, (FCPA), prohibits corporations and individuals from engaging in certain activities to obtain or retain business or to influence a person working in an official capacity. It is illegal to pay, offer to pay or authorize the payment of anything of value to any official of another country, government staff member, political party or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in that capacity.

ITEM 1A. RISK FACTORS

RISKS RELATED TO OUR FINANCIAL POSITION AND OUR CAPITAL RESOURCES

We will likely need additional capital to fund our operations. If we are unable to obtain sufficient capital, we will need to curtail and reduce our operations and costs and modify our business strategy.

Our operations have consumed substantial amounts of cash. To date, we have financedWe are currently financing our operations primarily through the sale of capital stock, proceeds from term loan agreements, the receipt of license fees, milestone payments, research and development funding and royalty paymentsrevenues from our collaboration partners,sales of YUTIQ® and product sales. In 2019, we commenced the U.S. launch ofDEXYCU® to our first two commercial products, YUTIQ and DEXYCU, and wecommercialization partners. We are developing EYP-1901 as a potential six-month sustained delivery treatment for wet AMD as well a treatment for non-proliferative diabetic retinopathy (NPDR), and NPDR.diabetic macular edema (DME). However, we have no expectation of revenues from our research and development programs, including EYP-1901, prior to the successful completion of clinical trials for such programs. Therefore, we have no sufficient historical evidence to assert that it is probable that we will receive sufficient revenues from our product sales to fund operations. As of December 31, 2022,2023, our cash, cash equivalents, and investments in marketable securities totaled $144.6$331.0 million. We believe that our cash, cash equivalents and investments in marketable securities, combined with anticipated net cash inflows from net product sales, will fund our operating plan through topline data for the Phase 3 wet AMD clinical trials related to EYP-1901 into the second half of 2024,2026, under current expectations regarding the timing and outcomes of our Phase 23 clinical trialstrial for EYP-1901 for the treatment of wet AMD, and NPDR.through Phase 2 clinical trials for the treatment of NPDR and DME. Due to the difficulty and uncertainty associated with the design and implementation of clinical trials, we will continue to assess our cash, cash equivalents, results from investments in marketable securities and future funding requirements. However, there is no assurance that additional funding will be achieved and that we will succeed in our future operations. Actual cash requirements could differ from our

projections due to many factors, including, the continued effect of the Pandemic on our business and the medical community, the timing and results of our Phase 2 and Phase 3 clinical trials for EYP-1901, additional investments in research and development programs the success of commercialization for YUTIQ, the loss of pass-through related separate payment for DEXYCU, the actual costs of these commercialization efforts,such as EYP-2301, the costs associated with the ongoing efforts associated withfor responding to the subpoena from the U.S. Attorney’s Office for the District of Massachusetts (DOJ) seeking production of documents related to sales, marketing and promotional practices, including as pertain to DEXYCU® (DOJ Investigation)Subpoena), higher interest rates, inflation, supply shortages, competing technological and market developments, and the costs of any strategic acquisitions and/or development of complementary business opportunities.

If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we will need to curtail and reduce our operations and costs, and modify our business strategy, which may require us to, among other things:

33

We have incurred significant losses since our inception and anticipate that we will continue to incur losses for the foreseeable future.

We have incurred significant losses since our inception have not generated significant revenue from commercial sales of our products and are not profitable. Investment in drug development is highly speculative because it entails substantial upfront operating expenses and significant risk that a product candidate will fail to successfully complete clinical trials, gain regulatory approval or become commercially viable. We continue to incur significant operating expenses due primarily to investments in clinical trials, sales and marketing infrastructure, research and development, and other expenses related to our ongoing operations. For the years ended December 31, 20222023 and 2021,2022, we had losses from operations of $99.6$75.1 million and $55.3$99.6 million, respectively, and net losses of $102.3$70.8 million and $58.4$102.3 million, respectively, and we had a total accumulated deficit of $671.4$742.1 million at December 31, 2022.2023.

We expect to continue to incur significant expenses and operating losses for the foreseeable future. We anticipate that our expenses will continue to be significant if, and as, we:

We may never achieve profitability from future operations.

Our ability to generate revenue and achieve profitability depends on our ability, alone or with strategic collaboration partners, to successfully commercialize our current products and complete the development of, and obtain the regulatory approvals necessary for, the manufacture and commercialization of our product candidates, including EYP-1901. To become and remain profitable, we must succeed in developing and commercializing products that generate significant revenue. This will require us to be successful in a range of challenging activities, including completing pre-clinical testing and clinical trials of our product candidates, discovering additional product candidates, obtaining regulatory approval for these product candidates, manufacturing, marketing, and selling any products for which we or our

licensees may obtain regulatory approval, satisfying any post-marketing requirements and obtaining reimbursement for our products from private insurance or government payors. We do not know the extent to which YUTIQ or DEXYCU, or any of our product candidates, including EYP-1901, if approved, will generate significant revenue for us, if at all. We may never succeed in these activities and, even if we do, we may never generate revenues significant enough to achieve profitability. Because of the numerous risks and uncertainties associated with pharmaceutical product development and commercialization, we are unable to accurately project when or if we will be able to achieve profitability from operations. Even if we do so, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our research and development efforts, diversify

34

our product offerings, or even continue our operations. Our ability to generate revenue from our current or future products and product candidates will depend on a number of factors, including:

We received a subpoena from the U.S. Attorney’s Office for the District of Massachusetts seeking production of documents related to sales, marketing and promotional practices, including as pertain to DEXYCU®. If the DOJ commences an action against us, the action could have a material adverse effect on our business, financial condition, results of operations, and cash flows. In addition, we have expended and expect to continue to expend significant financial and managerial resources responding to the DOJ subpoena, which could also have a material adverse effect on our business, financial condition, results of operations, and cash flows.

In August 2022, the Company received a subpoena from the U.S. Attorney’s Office for the District of Massachusetts (DOJ) seeking production of documents related to sales, marketing, and promotional practices, including as pertain to DEXYCU®. We (DOJ Subpoena).We are cooperating fully with the government in connection with this matter. We cannot predict the outcome of the DOJ Investigation,Subpoena, and there can be no assurance that the DOJ will not commence an action against us, or as to what the ultimate outcome of any such DOJ InvestigationSubpoena might be. Under applicable law, the DOJ has the ability to impose sanctions on companies which are found to have violated the provisions of applicable laws, including civil monetary penalties and other remedies. The resolution of any such enforcement action, should there be one, could have a material adverse effect on our business, financial condition, results of operations, and cash flows. We have expended and expect to continue to expend significant financial and managerial resources responding to the DOJ subpoena,Subpoena, which could also have a material adverse effect on our business, financial condition, results of operations, and cash flows.

The ongoing novel coronavirus (COVID-19) pandemic has had, and may continue to have, a material and adverse impact on our business.

The ongoing COVID-19 coronavirus pandemic (the Pandemic) has had a material and adverse impact on the Company’s business pursuant to a reduction in physician office visits impacting YUTIQ, specifically in early 2022. Going forward, the duration and full extent to which the Pandemic impacts the Company’s business, revenues, financial condition and cash flows depend on future developments that are highly uncertain, subject to change and are difficult to predict, including new information that may emerge concerning the Pandemic, and may cause intermittent or prolonged periods of reduced patient services at the Company’s customers’ facilities, which may negatively affect customer demand. The Company’s revenues, financial condition and cash flows may be adversely affected in the future as well. The Company is continuously monitoring the Pandemic and its potential effect on the Company’s financial position, results of operations and cash flows. Although the U.S. government has announced its intention to terminate the public health crisis associated with the Pandemic as of May 2023, there remains an uncertainty about the potential future impact of the Pandemic on the Company’s business. This uncertainty could have an impact in future periods on certain estimates used in the preparation of the Company’s periodic financial results, including reserves for variable consideration related to product sales, realizability of certain receivables and assessment for excess or obsolete inventory. Uncertainty around the extent and length of time of the Pandemic, and any future related financial impact cannot be reasonably estimated at this time.

While we cannot presently predict the future scope and severity of current or any potential business shutdowns or disruptions related to COVID-19, if we or any of the third parties with whom we engage, including the suppliers, manufacturers and other third parties in our global supply chain, clinical trial sites, clinical research organizations, patients who may be candidates for clinical trials, regulators, surgeons, ASCs, potential business development partners and other third parties with whom we conduct business, were to experience prolonged shutdowns or other business disruptions, including the imposition of restrictions on the export or import of our key supplies from countries outside of the United States, our ability to conduct our business in the manner and on the timelines

35

presently planned could be materially and negatively impacted. Further, any sustained disruption in the capital markets from the Pandemic could negatively impact our ability to raise capital.

To the extent the Pandemic continues to adversely affect our business, results of operations, financial condition and cash flows, it may also heighten many of the other risks described herein as well as in any amendment or update to our risk factors reflected in subsequent filings with the SEC.

The ultimate impact of the Pandemic on our business, results of operations, financial condition and cash flows is dependent on future developments, which are still highly uncertain and cannot be predicted with confidence, including the duration of the Pandemic, as well as the timing and phasing of business reopening, including the full resumption of the performance of elective surgical procedures such as cataract surgeries.

We will need to raise additional capital in the future, which may not be available on favorable terms and may be dilutive to stockholders or impose operational restrictions.

We will need to raise additional capital in the future to help fund the development and commercialization of EYP-1901 and our other product candidates, if approved, and the continued commercialization of YUTIQ.approved. The amount of additional capital we will require will be influenced by many factors, including, but not limited to:

We do not know if additional capital will be available to us when needed or on terms favorable to us or our stockholders. Collaboration, licensing or other commercial agreements may not be available on favorable terms, or at all. If we seek to sell our equity securities under our at-the-market (ATM) program or in another offering, we do not know whether and to what extent we will be able to do so, or on what terms. Further, the rules and regulations of the Nasdaq Stock Market LLC, (Nasdaq), require us to obtain stockholder approval for sales of our equity securities under certain circumstances, which could delay or prevent us from raising additional capital from such sales. Also, the state of the economy and financial and credit markets at the time or times we seek any additional financing may make it more difficult or more expensive to obtain. If available, additional equity financing may be dilutive to stockholders, debt financing may involve restrictive covenants or other unfavorable terms and dilute our existing stockholders’ equity, and funding through collaboration, licensing or other commercial agreements may be on unfavorable terms, including requiring us to relinquish rights to certain of our technologies or products. If adequate financing is not available if and when needed, we may delay, reduce the scope of, or eliminate research or development programs, postpone or cancel the pursuit of product candidates such as EYP-1901, including pre-clinical and clinical trials and new business opportunities, independent U.S. commercialization of YUTIQ, or other new products, if any, reduce staff and operating costs, or otherwise significantly curtail our operations to reduce our cash requirements and extend our capital.

Our failure to comply with the covenants or other terms$82.5 million cash plus royalties is dependent on Alimera’s effective sale and distribution of the Credit Facilities, including as a resultYUTIQ® outside of events beyond our control, could result in a default under the SVB Loan Agreement that would materiallyChina, Hong Kong, Taiwan, Macau, and adversely affect the ongoing viability of our business.Southeast Asia.

On March 9, 2022 (the SVB Closing Date), we entered into a loan and security agreement (the SVB Loan Agreement) among us, as borrower, and Silicon Valley Bank, as lender (SVB), providing for (i) a senior secured term loan facility of $30 million (the Term Facility) and (ii) a senior secured revolving credit facility of up to $15.0 million (the Revolving Facility and together with the Term Facility, the Credit Facilities). The maximum amount available for borrowing at any time under the Revolving Facility is limited to a borrowing base valuation of our eligible accounts receivable. On the SVB Closing Date, $30 million of the Term Facility and approximately $11.5 million of the Revolving Facility, were advanced, to pay off the CRG Loan, including the accrued interests

through this date. We utilizedPursuant to our PRA with Alimera, the proceeds fromCompany agreed to grant to Alimera an exclusive and sublicensable right and license under the Credit Facilities, together with cash on hand,Company’s and its affiliates’ interest in certain of the Company’s and its affiliates’ intellectual property to develop, manufacture, sell, commercialize and otherwise exploit certain products, including YUTIQ® (fluocinolone acetonide intravitreal implant or FA) 0.18 mg, for the repaymenttreatment and prevention of uveitis in full of all outstanding obligations under our term loan agreement (the CRG Credit Agreement) with CRG Servicing LLC (CRG).

The loans under the Credit Facilities are dueentire world except Europe, the Middle East and payable on January 1, 2027 (the Maturity Date). The Credit Facilities bear interest that is payable monthly in arrears at a per annum rate (subject to increase during an event of default) equal to (i) with respectAfrica. Pursuant to the Term Facility,agreement, Alimera paid the greater of (x) the Wall Street Journal prime rate plus 2.25% and (y) 5.50% and (ii) with respect to the Revolving Facility, the Wall Street Journal Prime Rate. An unused commitment fee of 0.25% per annum applies to unutilized borrowing capacity under the Revolving Facility. Commencing on February 1, 2024, we are required to repay the principal of the Term Facility in 36 consecutive equal monthly installments. At maturity or if earlier prepaid, we will also be required to pay an exit fee equal to 2.00% of the aggregate principal amount of the Term Facility.

We may makeCompany a voluntary prepayment of the Term Facility, in whole but not in part, at any time. Subject to certain exceptions, we are also$75 million cash upfront payment (Upfront Payment). Alimera is required to make mandatory prepayments of outstanding loans under the Credit Facilities with the proceeds of asset sales and insurance proceeds, which amounts in the case of the Revolving Facility, subject to the conditions set forth in the SVB Loan Agreement, may be re-borrowed. All voluntary and mandatory prepayments of the Term Facility are subject to the payment of prepayment premiums as follows: (i) if prepayment occurs on or prior to the first anniversary of the SVB Closing Date, an amount equal to 3.0% of the aggregate outstanding principal amount of the Term Facility being prepaid, (ii) if prepayment occurs after the first anniversary of the SVB Closing Date and on or prior to the second anniversary of the SVB Closing Date, 2.0% of the aggregate outstanding principal amount of the Term Facility being prepaid, (iii) if prepayment occurs after the second anniversary of the SVB Closing Date and on or prior to the third anniversary of the SVB Closing Date, 1.0% of the aggregate outstanding principal amount of the Term Facility being prepaid and (iv) if prepayment occurs after the third anniversary of the SVB Closing Date but prior to the Maturity Date, an amount equal to 0.50% of the aggregate outstanding principal amount of the Term Facility being prepaid. The prepayment of the Term Facility in full is also subject to the payment of an exit fee of $600,000. We may voluntarily terminate the Revolving Facility at any time, subject to the payment of a termination fee as follows: (i) if such termination occurs on or prior to the first anniversary of the Closing Date, an amount equal to 3.0% of the Revolving Facility and (ii) if such termination occurs after the first anniversary of the Closing Date, 1.0% of the Revolving Facility.

Certain of our future subsidiaries will be required to become co-borrowers under the SVB Loan Agreement or guarantee the obligations of ours under the SVB Loan Agreement. Our obligations under the SVB Loan Agreement and the guarantee of such obligations are secured by a pledge of substantially all of our and such subsidiaries’ assets, excluding intellectual property.

The SVB Loan Agreement contains affirmative and negative covenants customary for financings of this type, including limitations on our and our subsidiaries’ abilities, among other things, to incur additional debt, grant or permit additional liens, make investments and acquisitions, merge or consolidate with others, dispose of assets, pay dividends and distributions, enter into affiliate transactions and change our line of business, in each case, subject to certain exceptions. On March 7, 2023, the Company and SVB entered into an amendment to the SVB Loan Agreement, modifying thefour quarterly financial covenants of the agreement. Pursuant to the amendment, commencing upon December 31, 2022, the Company is required to maintain, at all times, unrestricted and unencumbered cash and cash equivalents in an amount equal to the greater of (i) $50,000,000 and (ii) the Company’s six-month Cash BurnGuaranteed Payments (as defined in the SVB Loan Agreement).

If we do not maintain compliance withPRA) to the continuing covenants and other terms and conditionsCompany totaling $7.5 million during 2024. Alimera is also required to pay royalties to the Company from 2025 to 2028 at a percentage of the Credit Facilities or secure a waiver for any non-compliance, then SVB may choose to declare an eventlow-to-mid double digits of default and require that we immediately repay all amounts outstanding, plus penalties and interest, including an exit fee, any termination fees and any prepayment fees, and foreclose on the collateral granted to them to secure such indebtedness. Such repayment would have a material adverse effect on our business, operating results and financial condition.

In addition, the repayment of all unpaid principal and accrued interest under the Credit Facilities may be accelerated upon consummation of a specified change of control transaction or the occurrenceAlimera’s annual U.S. net sales of certain other events of default (as specified in the SVB Loan Agreement), including, among other things:products (including YUTIQ

We cannot predict what success, if any, applicable cure period set forth in the SVB Loan Agreement, upon the occurrence of an event of default, SVBAlimera may accelerate all or any amounts outstandinghave with respect to sales of YUTIQ® and, therefore, it is uncertain as to when we may receive the Credit Facilities (principal, accrued interest, exit fee, any termination feesroyalties and any prepayment fees). Our assets or cash flow may not be sufficient to fully repay our obligations under the SVB Loan Agreement if the obligations thereunder are accelerated upon an event of default. Further, if we are unable to repay, refinance or restructure our obligations under the SVB Loan Agreement, SVB could proceed to protect and enforce their rights under the SVB Loan Agreement by exercising such remedies as are available to SVB thereunder and in respect thereof under applicable law, either by suit in equity or by actionwill receive any royalties at law, or both, whether for specific performance of any covenant or other agreement contained in the SVB Loan Agreement or in aid of the exercise of any power granted in the SVB Loan Agreement. The foregoing would materially and adversely affect the ongoing viability of our business.

Our Loan Agreement contains restrictions that limit our flexibility in operating our business.

The SVB Loan Agreement contains various covenants that limit our ability to engage in specified types of transactions without SVB’s prior consent. These covenants limit our ability to, among other things:

The covenants in our Loan Agreement may limit our ability to take certain actions that may be in our long-term best interests.all. In the event that we breach oneAlimera fails to execute the effective sale and distribution of YUTIQ® in the specified regions the royalties contemplated under the PRA could be adversely impacted in total, or more covenants, SVB may choose to declare an event of defaultin part, and require that we immediately repay all amounts outstanding, plus penalties and interest, including the exit fee, any termination fees and any prepayment fees, terminate their commitments to extend further credit and foreclose on the collateral granted to them to secure such indebtedness. Such repayment could have a material adverse effect on our business operating results and financial condition.

Certain potential payments to the Lenders could impede a sale of our company.

Subject to certain exceptions, we are also required to make mandatory prepayments of outstanding loans under the Credit Facilities with the proceeds of assets sales and insurance proceeds, which amounts in the case of the Revolving Facility, subject to the conditions set forth in the Loan Agreement, may re-borrowed.

All voluntary and mandatory prepayments of the Term Facility are subject to the payment of prepayment premiums as follows: (i) if prepayment occurs on or prior to the first anniversary of the SVB Closing Date, an amount equal to 3.0% of the aggregate outstanding principal amount of the Term Facility being prepaid, (ii) if prepayment occurs after the first anniversary of the SVB Closing Date and on or prior to the second anniversary of the SVB Closing Date, 2.0% of the aggregate outstanding principal amount of the Term Facility being prepaid, (iii) if prepayment occurs after the second anniversary of the SVB Closing Date and on or prior to the third anniversary of the SVB Closing Date, 1.0% of the aggregate outstanding principal amount of the Term Facility being prepaid and (iii) if prepayment occurs after the third anniversary of the SVB Closing Date but prior to the Maturity Date, an amount equal to 0.50% of the aggregate outstanding principal amount of the Term Facility being prepaid. The prepayment of the Term Facility in full is also subject to the payment of an exit fee of $600,000. We may voluntarily terminate the Revolving Facility at any time, subject to the payment of a termination fee as follows: (i) if such termination occurs on or prior to the first anniversary of the Closing Date, an amount equal to 3.0% of the Revolving Facility and (ii) if such termination occurs after the first anniversary of the Closing Date, 1.0% of the Revolving Facility.

These provisions may make it more costly for a potential acquirer to engage in a business combination transaction with us. Provisions that have the effect of discouraging, delaying or preventing a change in control could discourage a third party from attempting to acquire us, limit the opportunity for our stockholders to receive a premium for their shares of our common stock and could also affect the price that some investors are willing to pay for our common stock.

To service our indebtedness, we will require a significant amount of cash and our ability to generate cash depends on many factors beyond our control.

Our ability to make cash payments on our indebtedness will depend on our ability to generate significant operating cash flow in the future. This ability is, to a significant extent, subject to general economic, financial, competitive, legislative, regulatory and other factors, that will be beyond our control. In addition, our business may not generate sufficient cash flow from operations to enable us to pay our indebtedness or to fund our other liquidity needs. In any such circumstance, we may need to refinance all or a portion of our indebtedness, on or before maturity. We may not be able to refinance any indebtedness on commercially reasonable terms or at all. If we cannot service our indebtedness, we may have to take actions such as selling assets, seeking additional equity or reducing or delaying capital expenditures, strategic acquisitions and investments. Any such action, if necessary, may not be effected on commercially reasonable terms or at all. The instruments governing our indebtedness may restrict our ability to sell assets and our use of the proceeds from such sales.

Our profitability will be impacted by our obligations to make royalty and milestone payments to the former securityholders of Icon Bioscience, Inc. and other third-party collaborators.

In connection with our acquisition of Icon Bioscience, Inc. (Icon) in March 2018 (the Icon Acquisition), we are obligated to pay certain post-closing contingent cash payments upon the achievement of specified milestones and based upon certain net sales and partnering revenue standards, in each case subject to the terms and conditions set forth in the Merger Agreement, dated March 28, 2018 (the Merger Agreement). These future obligations include (i) sales milestone payments totaling up to $95.0 million, beginning no earlier than three years after the October 1, 2018 effective date of the pass-through reimbursement code approved by CMS, upon the achievement of certain sales thresholds and subject to certain CMS reimbursement conditions set forth in the Merger Agreement, (ii) quarterly earn-out payments equal to 12% on net sales of DEXYCU, which earn-out payments will increase to 16% of net sales of DEXYCU in a given year beginning in the calendar quarter for a given year to the extent aggregate annual consideration of DEXYCU exceeds $200.0 million in such year, (iii) quarterly earn-out payments equal to 20% of partnering revenue received by us for DEXYCU outside of the U.S., and (iv) single-digit percentage quarterly earn-out payments with respect to net sales and/or partnering income, if any, resulting from future clinical development, regulatory approval and commercialization of any other product candidates we might develop utilizing the Verisome technology acquired in the Icon Acquisition. For the year ended December 31, 2022, we accrued DEXYCU product revenue-based royalty expense of $1.6 million. Our profitability with respect to DEXYCU is impacted by our obligations to make payments to the former securityholders of Icon. Our obligations to the former securityholders of Icon and other third-party collaborators could have a material adverse effect on our business, financial condition and results of operations if we are unable to manage our operating costs and expenses at profitable levels. Going forward, we anticipate payments to ICON to be inconsequential pursuant to the CY 2023 Medicare Hospital OPPS and ASC Payment System Final Rule, which was issued November 1, 2022, terminating pass-through related separate payment for certain drugs, including DEXYCU, beyond its current expiration date of December 31, 2022.harmed.

Our ability to use our net operating loss carryforwards and other tax attributes may be limited.

As of December 31, 2022, including pre-acquisition amounts related to Icon,2023, we had U.S. net operating loss (NOL) carryforwards of approximately $321.6$296.5 million for U.S. federal income tax and approximately $264.2$254.7 million for state income tax purposes available to offset future taxable income, and U.S. federal and state research and development tax credits of approximately $7.2$8.9 million, prior to consideration of annual limitations that may be imposed under Section 382 of the Internal Revenue Code of 1986, as amended (Section 382). Our U.S. NOL carryforwards begin to expire in 2023 if not utilized.

Our U.S. NOL and tax credit carryforwards could expire unused and be unavailable to offset future income tax liabilities. Under Section 382, and corresponding provisions of U.S. state law, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-change U.S. NOLs and other pre-change tax attributes, such as research and development tax credits, to offset its post-change income may be limited. The latest analysis performed under Section 382, performed through September 30, 2018, confirmed that the exercise of certain warrants in late September 2018 resulted in a greater than 50% cumulative ownership change, which will cause annual limitations on the use of our then existing NOL balances and other pre-change tax attributes. As a result, if we earn net taxable income in future periods, our ability to use our pre-change U.S. NOL carryforwards to offset U.S. federal taxable income will be subject to limitations, which could potentially result in increased future tax liabilities to us.

In addition, we may experience additional ownership changes in the future as a result of subsequent shifts in our stock ownership, including through completed or contemplated financings, some of which may be outside of our control. If we determine that a future ownership change has occurred and our ability to use our historical net operating loss and tax credit carryforwards is materially limited, it would harm our future operating results by effectively increasing our future tax obligations.

RISKS RELATED TO THE REGULATORY APPROVAL AND CLINICAL DEVELOPMENT OF OUR PRODUCT CANDIDATES

The outcomes of clinical trials are uncertain, and delays in the completion of or the termination of any clinical trial of EYP-1901 or our other product candidates could harm our business, financial condition, and prospects.

Our research and development program for our lead product candidate, EYP-1901, and certain of our other product candidates, are still in development. We must demonstrate EYP-1901’s and our other product candidates’ safety and efficacy in humans through extensive clinical testing. Such testing is expensive and time-consuming and requires specialized knowledge and expertise.

Clinical trials are expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. The clinical trial process is also time-consuming, and the outcome is not certain. We estimate that clinical trials of our product candidates will take multiple years to complete. Failure can occur at any stage of a clinical trial, and we could encounter problems that cause us to abandon or repeat clinical trials. The commencement and completion of clinical trials may be delayed or precluded by a number of factors, including:

We, the FDA, other regulatory authorities outside the United States, or an IRB may suspend a clinical trial at any time for various reasons, including if it appears that the clinical trial is exposing participants to unacceptable health risks or if the FDA or one or more other regulatory authorities outside the United States find deficiencies in our INDinvestigational new drug application or similar application outside the United States or the conduct of the trial. If we experience delays in the completion of, or the termination of, any clinical trial of any of our product candidates, including EYP-1901, the commercial prospects of such product candidate will be

harmed, and our ability to generate product revenues from such product candidate will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process, and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition, results of operations, cash

40

flows and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates.

Clinical trial results may fail to support continued clinical investigations and/or approval of EYP-1901 or our other product candidates.

Even if our clinical trials are successfully completed as planned, the results may not support approval of EYP-1901 or our other product candidates under the laws and regulations of the FDA or other regulatory authorities outside the United States. The clinical trial process may fail to demonstrate that our product candidates are both safe and effective for their intended uses. Pre-clinical and clinical data and analyses are often able to be interpreted in different ways. Even if we view our results favorably, if a regulatory authority has a different view, we may still fail to obtain regulatory approval of our product candidates. This, in turn, would significantly adversely affect our business prospects.

We may expend significant resources to pursue our lead product candidate, EYP-1901 for the potential treatment of wet AMD, NPDR and DME and fail to capitalize on the potential of EYP-1901, or our other product candidates, for the potential treatment of other indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on research programs and product candidates for specific indications. Specifically, with regard to EYP-1901, we initially focused our efforts on the treatment of wet AMD, but have since expanded our efforts to include the treatment of NPDR and DME. As a result, we may forego or delay pursuit of opportunities with EYP-1901 or other product candidates for the treatment of other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable products. Furthermore, until such time as we are able to build a broader product candidate pipeline, if ever, any adverse developments with respect to our leading product candidate, EYP-1901, would have a more significant adverse effect on our overall business than if we maintained a broader portfolio of product candidates.

We have historically based our research and development efforts primarily on our proprietary technologies for the treatment of chronic eye diseases. As a result of pursuing the development of product candidates using our proprietary technologies, we may fail to develop product candidates or address indications based on other scientific approaches that may offer greater commercial potential or for which there is a greater likelihood of success. Research programs to identify new product candidates require substantial technical, financial and human resources. These research programs may initially show promise in identifying potential product candidates, yet fail to yield product candidates for clinical development.

InitialPhase 1 or 2 results from a clinical trial do not ensure that the trial will be successful and success in early stage clinical trials does not ensure success in later-stage clinical trials.

Results from pre-clinical testing, early clinical trials, prior clinical trials, investigator-sponsored studies, and other data and information often do not accurately predict final pivotal clinical trial results. EYP-1901 relies on vorolanib as its active pharmaceutical agent. Vorolanib is a small molecule TKI that has been previously studied by Tyrogenex in Phase 1 and 2 clinical trials as an orally delivered therapy for the treatment of wet AMD. The Phase 2 clinical trial was discontinued due to systemic toxicity. There can be no assurance that such systemic toxicities will not occur in our clinical trial for EYP-1901. In addition, data from one pivotal clinical trial may not be predictive of the results of other pivotal clinical trials for the same product candidate, even if the trial designs are the same or similar. Data obtained from pre-clinical studies and clinical trials are susceptible to varying interpretations, which may delay, limit or prevent regulatory approval. Adverse side effects may be observed in clinical trials that delay, limit or prevent regulatory approval, and even after a product candidate has received marketing approval, the emergence of adverse side effects in more widespread clinical practice may cause the product’s regulatory approval to be limited or even rescinded. Additional trials necessary for approval may not be undertaken or may ultimately fail to establish the safety and efficacy of our product candidates.

In addition, while the clinical trials of our product candidates, including our lead product candidate, EYP-1901, are designed based on the available relevant information, in view of the uncertainties inherent in drug development, such clinical trials may not be designed with a focus on indications, patient populations, dosing regimens, safety or efficacy parameters or other variables that will provide the necessary safety and efficacy data to support regulatory approval to commercialize the product. In addition, the methods we select to assess particular safety or efficacy parameters may not yield statistically significant results regarding our product candidates’ effects on patients. Even if we believe the data collected from clinical trials of our product candidates are promising, these data may not be sufficient to support approval by the FDA or foreign regulatory authorities. Pre-clinical and clinical data can be

interpreted in different ways. Accordingly, the FDA or foreign regulatory authorities could interpret these data in different ways from us or our partners, which could delay, limit or prevent regulatory approval.

41Interim, “top-line” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

We face risks relatedFrom time to health epidemics and outbreaks, including the Pandemic, which could significantly disrupt our preclinical studies and clinical trials.

We started conducting Phase 2 clinical trials for EYP-1901 in multiple jurisdictions within the U.S. in 2022. Enrollment of patients in these clinical trials and future clinical trials in these regionstime, we may be delayed due to the outbreak of the Pandemic. In addition, we rely on independent clinical investigators, contract research organizations and other third-party service providers to assist us in managing, monitoring and otherwise carrying outpublicly disclose preliminary or top-line data from our preclinical studies and clinical trials, which is based on a preliminary analysis of then-available data, and outbreaksthe results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. We also make assumptions, estimations, calculations, and conclusions as part of our analyses of data, and we may affect their abilitynot have received or had the opportunity to devote sufficient timefully and resources to our programs.carefully evaluate all data. As a result, the expected timeline fortop-line or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data readouts ofhave been received and fully evaluated. Top-line and preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the top-line or preliminary data we previously published. As a result, top-line and preliminary data should be viewed with caution until the final data are available.

From time to time, we may also disclose interim data from our preclinical studies and clinical trials. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and certainmore patient data become available or as patients from our clinical trials continue other treatments for their disease. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects. Further, disclosure of interim data by us or by our competitors could result in volatility in the price of our common stock. Further, others, including regulatory filingsagencies, may not accept or agree with our assumptions, estimates, calculations, conclusions, or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure. If the interim, top-line, or preliminary data that we report differ from final results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be negatively impacted,harmed, which could harm our business, operating results, prospects, or financial condition.

We may not be successful in our efforts to identify and successfully develop additional product candidates. Part of our strategy involves identifying product candidates. We may fail to identify and develop product candidates for clinical development for a number of reasons, including those discussed in these risk factors and also:

If we are unable to identify and successfully commercialize additional suitable product candidates, this would adversely affectimpact our business.business strategy and our financial position.

We may find it difficult to enroll patients in our clinical trials, which could delay or prevent clinical trials of our product candidates.

Identifying and qualifying patients to participate in clinical trials of our product candidates, including EYP-1901, is critical to our success. The timing of our clinical trials depends in part on the speed at which we can recruit patients to participate in testing our product candidates. If patients are unwilling to participate in our trials because of the COVID-19 pandemic and restrictions on travel or healthcare institution policies, negative publicity from adverse events in the biotechnology industries, public perception of vaccine safety issues or for other reasons, including competitive clinical trials for similar patient populations, the timeline for recruiting patients, conducting studies, and obtaining regulatory approval of potential products may be delayed. These delays could result in increased costs, delays in advancing our product development, delays in testing the effectiveness of our technology or termination of the clinical trials altogether.

We may not be able to identify, recruit, and enroll a sufficient number of patients, or those with required or desired characteristics to achieve diversity in a clinical trial, or complete our clinical trials in a timely manner. Patient enrollment is affected by a variety of factors including, among others:

We may not be able to initiate or continue clinical trials if we cannot enroll a sufficient number of eligible patients to participate in the clinical trials required by regulatory agencies.

Even if we enroll a sufficient number of eligible patients to initiate our clinical trials, we may be unable to maintain participation of these patients throughout the course of the clinical trial as required by the clinical trial protocol, in which event we may be unable to use the research results from those patients. If we have difficulty enrolling and maintaining the enrollment of a sufficient number of patients to conduct our clinical trials as planned, we may need to delay, limit, or terminate ongoing or planned clinical trials, any of which would have an adverse effect on our business.

We are largely dependent on the clinical and future commercial success of our lead product candidate, EYP-1901.

Our ability to generate revenues and become profitable will depend in large part on the future commercial success of our lead product candidate, EYP-1901, if it is approved for marketing. If EYP-1901 or any other product that we commercialize in the future does not gain an adequate level of acceptance among physicians, patients and third parties, we may not generate significant product

42

revenues or become profitable. Market acceptance by physicians, patients and third party payors of EYP-1901 or other products we may commercialize in the future will depend on a number of factors, some of which are beyond our control, including:

For example, even if EYP-1901 gains approval by the FDA, physicians and patients may not immediately be receptive to it and may be slow to adopt it. If EYP-1901 does not achieve an adequate level of acceptance among physicians, patients and third party payors, we may not generate meaningful revenues from EYP-1901 and we may not become profitable.

Future public health crises such as the COVID-19 pandemic may adversely impact, and pose risks to, certain elements of our business such as our preclinical studies and clinical trials, the nature and extent of which are highly uncertain and unpredictable.

Our global operations expose us to risks associated with public health crises, including epidemics and pandemics such as the previous COVID-19 pandemic. As it relates to EYP-1901 targeting wet AMD, we expect to start conducting Phase 3 clinical trials for EYP-1901 throughout the world in 2024. We also expect to continue with Phase 2 clinical trials for NPDR and for DME in 2024. Enrollment of patients in these clinical trials and future clinical trials in these regions may be delayed due to the outbreak of the health epidemics and outbreaks, for example, the previous COVID-19 pandemic. In addition, we rely on independent clinical investigators, contract research organizations and other third-party service providers to assist us in managing, monitoring and otherwise carrying out our preclinical studies and clinical trials, and outbreaks may affect their ability to devote sufficient time and resources to our programs. As a result, if a public health crisis were to occur in the future, the expected timeline for data readouts of our preclinical studies and clinical trials and certain regulatory filings may be negatively impacted, which would adversely affect our business.

RISKS RELATED TO THE COMMERCIALIZATION OF OUR PRODUCTS AND PRODUCT CANDIDATES

Our current business strategy relies in part on our ability to successfully commercialize our approved products;product candidates, if approved; however, the products may not achieve market acceptance or be commercially successful.

Our ability to continue to successfully commercialize our product candidates, if approved, products is important to the execution of our business strategy. Such products may not achieve broad market acceptance among retinal specialists and other doctors, patients, government health administration authorities and other third-party payors, and may not continue to be commercially successful in the U.S. The degree of market acceptance and commercial success of our approved productsproduct candidates will depend on a number of factors, including the following:

As many of these factors are beyond our control, we cannot assure you that we will ever be able to generate meaningful revenues through product sales. In particular, if governments, private insurers, governmental insurers, and other third-party payors do not provide adequate and timely coverage and reimbursement levels for our products or limit the frequency of administration, the market acceptance of our products and product candidates will be limited. Governments, governmental insurers, private insurers, and other third-party payors attempt to contain healthcare costs by limiting coverage and the level of reimbursement for products and, accordingly, they may challenge the price and cost-effectiveness of our products or refuse to provide coverage for our products. Any inability on

inability on our part to successfully commercialize YUTIQ in the U.S and DEXYCU internationally, and our other product candidates in the U.S. or any foreign territories where they may be approved, or any significant delay in such approvals, could have a material adverse impact on our ability to execute upon our business strategy and our future business prospects.

Our productsproduct and product candidates, if approved and commercialized, may become subject to unfavorable pricing regulations, third-party reimbursement practices, or healthcare reform initiatives which could harm our business.

The statutes and regulations that govern marketing approvals, pricing and reimbursement for new drug products vary widely from country to country. Some countries require approval of the sale price of a product before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product candidate in a particular country, but then be subject to price regulations that delay our commercial launch of the product candidate, possibly for lengthy time periods, which could negatively impact the revenues we are able to generate from the sale of the product candidate in that particular country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more of our products.

Our success also depends in part on the extent to which coverage and reimbursement for these productsour product candidates, once commercialized, and related treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, determine which medications they will cover and establish reimbursement levels. A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Third-party payors also may seek additional clinical evidence, beyond the data required to obtain marketing approval, demonstrating clinical benefits and value in specific patient populations, before covering our products for those patients. We cannot be sure that coverage and reimbursement will be available for any product candidate that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Coverage and reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. If reimbursement is not available or is available only to limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval. For example, under current Medicare Part B policy, payment to hospital outpatient departments and ASCs for drug and biological products furnished to patients as part of a surgical procedure is typically packaged into the payment for the associated procedure and thus not paid separately. Products granted pass-through status were excluded from this payment packaging policy and receive separate payment from the associated procedure for a period of three years. While DEXYCU had been granted pass-through status and had been receiving separate payment in these settings from Medicare, the CY 2023 Medicare Hospital OPPS and ASC Payment System Final Rule, which was issued November 1, 2022, terminated pass-through related separate payment for certain drugs, including DEXYCU, beyond its current expiration date of December 31, 2022. Effective January 1, 2023, payment for DEXYCU is packaged into the payment for the underlying procedure and no longer reimbursed separately, which will materially decrease our revenues from sales of DEXYCU and correspondingly have a material adverse effect on our results of operations and financial condition.

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA or comparable foreign regulatory authorities. Moreover, eligibility for coverage and reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacturing, selling and distribution costs. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net prices for products may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of products from countries where they may be sold at lower prices than in the U.S. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our inability to promptly obtain coverage and profitable reimbursement rates from both government-funded and private payors for any approved products that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products, and our overall financial condition.

WeOnce we commercialize any new products, we may participate in, and have certain price reporting obligations to, the Medicaid Drug Rebate Program. This program requires us to pay a rebate for each unit of drug reimbursed by Medicaid. The amount of the “basic” portion of the rebate for each product is set by law as the larger of: (i) 23.1% of quarterly average manufacturer price, or AMP, or (ii) the difference between quarterly AMP and the quarterly best price available from us to any commercial or non-governmental customer, or Best Price. AMP must be reported on a monthly and quarterly basis and Best Price is reported on a quarterly basis only. In addition, the rebate also includes the “additional” portion, which adjusts the overall rebate amount upward as an “inflation penalty” when the drug’s latest quarter’s AMP exceeds the drug’s AMP from the first full quarter of sales after launch, adjusted for increases in the Consumer Price Index-Urban. The upward adjustment in the rebate amount per unit is equal to the excess amount of the current AMP over the inflation-adjusted AMP from the

44

first full quarter of sales. The rebate amount is computed each quarter based on our report to CMSthe Centers for Medicare and Medicaid Services (CMS) of current quarterly AMP and Best Price for our drug. Rebates under the Medicaid Drug Rebate Program are currently capped at 100 percent of AMP, but thatno longer subject to a cap, is set to be removed, effective January 1, 2024, which could increase our rebate liability. We are required to report revisions to AMP or Best Price within a period not to exceed 12 quarters from the quarter in which the data was originally due. Any such revisions could have the impact of increasing or decreasing our rebate liability for prior quarters, depending on the direction of the revision. The Affordable Care Act made significant changes to the Medicaid Drug Rebate Program, and CMS issued a final regulation, which became effective on April 1, 2016, to implement the changes to the Medicaid Drug Rebate program under the Affordable Care Act. On December 21, 2020, CMS issued a final regulation that modified existing Medicaid Drug Rebate Program regulations to permit reporting multiple Best Price figures with regard to value based purchasing arrangements (beginning in

2022) and provided definitions for “line extension,” “new formulation,” and related terms with the practical effect of expanding the scope of drugs considered to be line extensions (beginning in 2022). While the regulatory provisions that purported to affect the applicability of the AMP and Best Price exclusions of manufacturer-sponsored patient benefit programs in the context of pharmacy benefit manager “accumulator” programs were invalidated by a court, accumulator and other such programs may continue to negatively affect us in other ways.

Federal law also requires that any manufacturer that participates in the Medicaid Drug Rebate Program also participate in the Public Health Service’s 340B drug pricing program in order for federal funds to be available for the manufacturer’s drugs under Medicaid and Medicare Part B. The 340B drug pricing program, which is administered by the Health Resources and Services Administration, or HRSA, requires participating manufacturers to agree to charge statutorily-defined covered entities no more than the 340B “ceiling price” for the manufacturer’s covered outpatient drugs. These 340B covered entities include, but are not limited to, a variety of community health clinics and other entities that receive health services grants from the Public Health Service, as well as hospitals that serve a disproportionate share of low-income patients. The 340B ceiling price is calculated using a statutory formula, which is based on the AMP and rebate amount for the covered outpatient drug as calculated under the Medicaid Drug Rebate Program. Any changes to the definition of AMP and the Medicaid rebate amount under the Affordable Care Act or other legislation could affect our 340B ceiling price calculations and negatively impact our results of operations.

HRSA issued a final regulation regarding the calculation of the 340B ceiling price and the imposition of civil monetary penalties on manufacturers that knowingly and intentionally overcharge covered entities, which became effective on January 1, 2019. It is currently unclear how HRSA will apply its enforcement authority under this regulation. HRSA has also implemented a ceiling price reporting requirement related to the 340B program under which we are required to report 340B ceiling prices to HRSA on a quarterly basis, and HRSA then publishes that information to covered entities. Moreover, under a final regulation effective January 13, 2021, HRSA newly established an administrative dispute resolution (ADR) process for claims by covered entities that a manufacturer has engaged in overcharging, and by manufacturers that a covered entity violated the prohibitions against diversion or duplicate discounts. Such claims are to be resolved through an ADR panel of government officials rendering a decision that could be appealed only in federal court. An ADR proceeding could subject us to onerous procedural requirements and could result in additional liability. In addition, legislation may be introduced that, if passed, would further expand the 340B program to additional covered entities or would require participating manufacturers to agree to provide 340B discounted pricing on drugs used in an inpatient setting.

Federal law also requires that a company that participates in the Medicaid Drug Rebate program report average sales price, or ASP, information each quarter to CMS for certain categories of drugs that are paid under the Medicare Part B program. For calendar quarters effective January 1, 2022, manufacturers are required to report the average sales price for certain drugs under the Medicare program regardless of whether they participate in the Medicaid Drug Rebate Program. Manufacturers calculate the ASP based on a statutorily defined formula as well as regulations and interpretations of the statute by CMS. CMS usesmay use these submissions to determine payment rates for drugs under Medicare Part B. Starting in 2023, manufacturers must pay refunds to Medicare for single source drugs or biologicals, or biosimilar biological products, reimbursed under Medicare Part B and packaged in single-dose containers or single-use packages, for units of discarded drug reimbursed by Medicare Part B in excess of 10 percent of total allowed charges under Medicare Part B for that drug. Manufacturers that fail to pay refunds could be subject to civil monetary penalties of 125 percent of the refund amount.

Statutory or regulatory changes or CMS guidance could affect the pricing of our approved products,product candidates, and could negatively affect our results of operations. On August 16, 2022, President Biden signed into law theThe IRA, which, among other things, requires the Secretary of Health and Human Services to negotiate, with respect to Medicare units and subject to a specified cap, the price of a set number of certain high Medicare spend drugs and biologicals per year starting in 2026. Effective January 2023, the IRA established a Medicare Part B inflation rebate scheme, under which, generally speaking, manufacturers will owe rebates if the average sales price of a Part B drug increases faster than the pace of inflation. Failure to timely pay a Part B inflation rebate is subject to a civil monetary penalty. Further, starting October 2022, the IRA established a Medicare Part D inflation rebate scheme, under which, generally speaking, manufacturers will owe additional rebates if the AMP of a Part D drug increases faster than the pace of inflation. Failure to timely pay a Part D inflation rebate is subject to a civil monetary penalty. In addition, manufacturers are currently required to provide a 70% discount on brand name prescription drugs utilized by Medicare Part D beneficiaries when those beneficiaries are in the coverage gap phase of the Part D benefit design. The IRA sunsets the coverage gap discount program starting in 2025 and replaces it

45

with a new manufacturer discount program and makes other reforms to the Part D benefit, which could increase our liability under Part D. These or any other public policy change could impact the market conditions for our products. We further expect continued scrutiny on government price reporting and pricing more generally from Congress, agencies, and other bodies.

In order to be eligible to have our products paid for with federal funds under the Medicaid and Medicare Part B programs and purchased by certain federal agencies and grantees, we must participate in the VA FSS pricing program. Under this program, we would be obligated to make our “innovator” drugs available for procurement on an FSS contract and charge a price to four federal agencies—VA, DoD, Public Health Service and U.S. Coast Guard—that is no higher than the statutory FCP. The FCP is based on the Non-FAMP, which we calculate and report to the VA on a quarterly and annual basis. We do not currently participate in the Tricare

Retail Pharmacy program, under which we would need to pay quarterly rebates on utilization of innovator products that are dispensed through the Tricare Retail Pharmacy network to TRICARE beneficiaries. The rebates are calculated as the difference between the annual Non-FAMP and FCP. The requirements under the 340B, FSS, and TRICARE programs will impact gross-to-net revenue for our current products and any product candidates that are commercialized in the future and could adversely affect our business and operating results.

We are shipping YUTIQ directly to physician offices or clinics to be administered to patients. YUTIQ is being shipped to physician offices or clinics primarily through specialty pharmacies and distributors. Most prefer to buy the product directly through our select distributors under a “buy and bill” model. Physicians who may not be willing to purchase our products through a specialty distributor because they do not prefer the buy and bill method may prefer to have another entity called a specialty pharmacy ship them the product at no cost to the physician. The specialty pharmacy bills the health plan for our product directly and then ships the product to the physician such that no costs are incurred by the physician. We have obtained a permanent “J” code for YUTIQ which assists physicians and hospitals in their ability to bill all payer types for the product.

We are shipping DEXYCU to ASCs, or to hospital outpatient surgical centers through specialty pharmacies and distributors. DEXYCU was being reimbursed for Medicare Part B patients in these settings through a transitional pass-through related separate payment when billed under the drug’s “J” code. The Final Rule did not extend pass-through related separate payment for expiring drugs, and therefore, DEXYCU no longer qualifies for separate payment effective January 1, 2023, and is subject to packaged payment rates, which will significantly limit our ability to gain utilization and subsequent revenues. In addition, in anticipation of the Final Rule, as a result of CY 2023 OPPS/ASC Proposed Rule, the Company entered into the Termination Agreement with ImprimisRx on October 7, 2022, pursuant to which ImprimisRx and the Company agreed to terminate the Agreements effective December 31, 2022. Effective January 1, 2023, there is significantly reduced commercial support for DEXYCU.

If we fail to comply with reporting and payment obligations under the Medicaid Drug Rebate program or other governmental pricing programs, we could be subject to additional reimbursement requirements, penalties, sanctions, and fines which could have a material adverse effect on our business, financial condition, results of operations, and growth prospects.

Our price reporting and other obligations under the Medicaid Drug Rebate Program, Medicare Part B, the 340B program, and the VA/FSS program are described in the risk factor entitled “Our products and product candidates, if approved and commercialized, may become subject to unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives which could harm our business.”business”. Pricing and rebate calculations vary across products and programs, are complex, and are often subject to interpretation by us, governmental or regulatory agencies, and the courts. In the case of Medicaid pricing data, if we become aware that our reporting for a prior period was incorrect or has changed as a result of a recalculation of the pricing data, we are obligated to resubmit the corrected data for up to three years after those data were originally due. Such restatements and recalculations will increase our costs for complying with the laws and regulations governing the Medicaid Drug Rebate program and could result in an overage or underage in our rebate liability for past quarters. Price recalculations also may affect the ceiling price at which we are required to offer our products under the 340B program and may require us to offer refunds to covered entities.

We are liable for errors associated with our submission of pricing data. That liability could be significant. In addition to retroactive Medicaid rebates and the potential for issuing 340B program refunds, if we are found to have knowingly submitted false AMP, Best Price, or Non-FAMP information to the government, we may be liable for significant civil monetary penalties per item of false information. If we are found to have made a misrepresentation in the reporting of our ASP, the Medicare statute provides for significant civil monetary penalties for each misrepresentation for each day in which the misrepresentation was applied. Our failure to submit monthly/quarterly AMP and Best Brice data on a timely basis could result in a significant civil monetary penalty per day for each day the information is late beyond the due date. Such conduct also could be grounds for CMS to terminate our Medicaid drug rebate agreement, in which case federal payments may not be available under Medicaid or Medicare Part B for our covered outpatient drugs. Significant civil monetary penalties also could apply to late submissions of Non-FAMP information. Civil monetary penalties could also be applied if we are found to have charged 340B covered entities more than the statutorily mandated ceiling price or HRSA could terminate our agreement to participate in the 340B program, in which case federal payments may not be available under Medicaid or Medicare Part B for our covered outpatient drugs. Moreover, under a final regulation effective January 13, 2021, HRSA newly established an ADR process that has jurisdiction over claims by covered entities that a manufacturer has engaged in

46

overcharging. An ADR proceeding could subject us to onerous procedural requirements and could result in additional liability. In addition, claims submitted to federally-funded healthcare programs, such as Medicare and Medicaid, for drugs priced based on incorrect pricing data provided by a manufacturer can implicate the federal civil False Claims Act. Finally, civil monetary penalties could be due if we fail to offer discounts to beneficiaries under the Medicare Part D coverage gap discount program. Furthermore, under the refund program for discarded drugs, manufacturers that fail to pay refunds could be subject to civil monetary penalties of 125 percent of the refund amount.

If we overcharge the government in connection with our FSS contract or our anticipated Tricare Agreement, whether due to a misstated FCP or otherwise, we are required to refund the difference to the government. Failure to make necessary disclosures and/or to identify contract overcharges can result in allegations against us under the False Claims Act and other laws and regulations. Unexpected refunds to the government, and responding to a government investigation or enforcement action, would be expensive and time-consuming, and could have a material adverse effect on our business, financial condition, results of operations, and growth prospects. We cannot assure you that our submissions will not be found by CMS or another governmental agency to be incomplete or incorrect.

There has been heightened governmental scrutiny in the U.S. of pharmaceutical pricing practices in light of the rising cost of prescription drugs. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. At both the federal and state level, legislatures are increasingly passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access, and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. One significant example of recent legislative action is the IRA, which was signed into law on August 16, 2022.IRA. The IRA contains a negotiation provision that requires the Secretary of Health and Human Services to negotiate, with respect to Medicare units and subject to a specified cap, the price of a set number of high Medicare spend drugs and biologicals per year starting in 2026. Under the drug price negotiation program, a drug may not be subjected to a negotiated price until at least nine years post-approval, and a biologic may not be subjected to a negotiated price until at least 13 years post-licensure. The IRA limits the negotiation eligibility for the 2026, 2027 and 2028 program years and afford

limited additional relief for “small biotech drugs” of certain small manufacturers which, among other things, represent a limited portion (as specified in the text) of Medicare program spending. The IRA also penalizes manufacturers of certain Medicare Part B and D drugs for price increases above inflation and makes several changes to the Medicare Part D benefit, including a limit on annual out-of-pocket costs, and a change in manufacturer liability under the program. The complete impact from the IRA is unknown because negotiated prices will not apply for Part D drugs until 2026, and two years later for Part B drugs. In keeping with this timeline, and the recent passage, we cannot predict the implications the IRA provisions will have on our business.

Even though regulatory approvals for YUTIQ® and DEXYCU® have been obtained in the U.S., we will still face extensive FDA regulatory requirements and may face future regulatory difficulties.

Even though regulatory approvals for YUTIQ® and DEXYCU® have been obtained in the U.S., the FDA and state regulatory authorities may still impose significant restrictions on the indicated uses or marketing of YUTIQ® and DEXYCU®, or impose ongoing requirements for potentially costly post-approval studies or post-marketing surveillance. For example, as part of its approval of DEXYCU® for the treatment of postoperative ocular inflammation, the FDA required under the Pediatric Research Equity Act (PREA), that a Phase 3/4 prospective, randomized, active treatment-controlled, parallel-design multicenter trial be conducted to evaluate the safety of DEXYCU® for the treatment of inflammation following ocular surgery for childhood cataract. This pediatric study will likely require us to undergo a costly and time-consuming development process. If we do not meet our obligations under the PREA for this pediatric study, the FDA may issue a non-compliance letter and may also consider DEXYCU® to be misbranded and subject to potential enforcement action.

We were advised by the FDA to show diligence and enroll at least one patient in the protocolled trial before submitting a new Deferral Extension Request.

We submitted a pediatric study protocol to the FDA as required. We have identified clinical sites and are continuingcontinued study start-up activities that have resulted inwith dosing of a first patient in January 2022. In February 2022, we requested a PREA Deferral Extension because of the unavoidable delays in this program due, among other things, to the Pandemic. The extension was granted by the FDA, extending the study deadline to June 30, 2025. As of December 31, 2023, the study remains ongoing.

We, areand with respect to YUTIQ®, Alimera, is also subject to ongoing FDA requirements governing the labeling, packaging, storage, distribution, safety surveillance, advertising, promotion, record-keeping and reporting of safety and other post-marketing information. The holder of an approved NDA is obligated to monitor and report adverse events and any failure of a product to meet the specifications in the NDA. The holder of an approved NDA must also submit new or supplemental applications and obtain FDA approval for certain changes to the approved

47

product, product labeling or manufacturing process. Advertising and promotional materials must comply with FDA regulations and may be subject to other potentially applicable federal and state laws. The applicable regulations in countries outside the U.S. grant similar powers to the competent authorities and impose similar obligations on companies.

In addition, manufacturers of drug products and their facilities are subject to payment of substantial user fees and continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP regulations and adherence to commitments made in the NDA. We also need to comply with some of the FDA’s manufacturing regulations for devices with respect to YUTIQ.YUTIQ®. We and our third-party providers are generally required to maintain compliance with cGMP and other stringent requirements and are subject to inspections by the FDA and comparable agencies in other jurisdictions to confirm such compliance. Any delay, interruption or other issues that arise in the manufacture, fill-finish, packaging, or storage of our products as a result of a failure of our facilities or the facilities or operations of third parties to pass any regulatory agency inspection could significantly impair our commercial partners' ability to develop and commercialize our products. Significant noncompliance could also result in the imposition of monetary penalties or other civil or criminal sanctions and damage our reputation.

In addition to cGMP, the FDA requires that YUTIQ® and DEXYCU® manufacturers comply with certain provisions of the Quality System Regulation, or QSR, particularly in light of the D.C. Circuit Court of Appeals decision in Genus Medical Technologies LLC v. FDA. The QSR sets forth the FDA’s manufacturing quality standards for medical devices, and other applicable government regulations and corresponding foreign standards. If we, or a regulatory authority, discover previously unknown problems with YUTIQ® or DEXYCU®, such as adverse events of unanticipated severity or frequency, or problems with a facility where the product is manufactured, a regulatory authority may impose restrictions relative to YUTIQ®, DEXYCU® or their respective manufacturing facilities, including requiring recall or withdrawal of the product from the market, suspension of manufacturing, or other FDA action or other action by foreign regulatory authorities.

If we, and with respect to YUTIQ®, Alimera, fail to comply with applicable regulatory requirements for YUTIQ® or DEXYCU®, a regulatory authority may:

Our relationships with physicians, patients and payors in the U.S. are subject to applicable anti-kickback, fraud and abuse laws and regulations. In addition, we are subject to patient privacy regulation by both the federal government and the states in which we conduct our business. Our failure to comply with these laws could expose us to criminal, civil and administrative sanctions, reputational harm, and could harm our results of operations, and financial conditions.

Our current and future operations with respect to the commercialization of YUTIQ and DEXYCUnew product candidates are subject to various U.S. federal and state healthcare laws and regulations. These laws impact, among other things, our proposed sales, marketing, support and education programs and constrain our business and financial arrangements and relationships with third-party payors, healthcare professionals and others who may prescribe, recommend, purchase or provide our products, and other parties through which we may market, sell and distribute our products.product candidates. Finally, our current and future operations are subject to additional healthcare-related statutory and regulatory requirements and enforcement by foreign regulatory authorities in jurisdictions in which we conduct our business. TheRefer to “Healthcare Fraud and Abuse Laws” section of Government Regulation for a more in-depth description of these laws, which include, but are not limited to, the following:

48

The shifting commercial compliance environment and the need to build and maintain robust and expandable systems to comply with different compliance or reporting requirements in multiple jurisdictions increase the possibility that a healthcare or pharmaceutical company may fail to comply fully with one or more of these requirements. Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations may involve substantial costs. It is possible that governmental authorities will conclude that our business practices do not comply with applicable fraud and abuse or other healthcare laws and regulations or guidance. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, exclusion from government funded healthcare programs, such as Medicare and Medicaid, additional oversight

49

and reporting requirements if we become subject to a corporate integrity agreement to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations. If any of the physicians or other providers or entities with whom we expect to do business is found not to be in compliance with applicable laws, they may be subject to the same criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity, which could harm our financial condition and divert resources and the attention of our management from operating our business.

The occurrence of any event or penalty described above may inhibit our ability to commercialize YUTIQour product candidates in the U.S. and generate revenues, which would have a material adverse effect on our business, financial condition, and results of operations.

If the market opportunities for our products and product candidates, including EYP-1901, are smaller than we believe they are, our results of operations may be adversely affected and our business may suffer.

We focus our research and product development primarily on treatments for eye diseases. Our projections of both the number of people who have these diseases, as well as the subset of people with these diseases who have the potential to benefit from treatment with our products and product candidates, such as our projections of the number of patients with wet AMD, NPDR, and DME who may benefit from treatment with EYP-1901 if it is approved for use, are based on estimates. These estimates may prove to be incorrect and new studies or clinical trials may change the estimated incidence or prevalence of these diseases. The number of patients in the U.S. and elsewhere may turn out to be lower than expected, may not be otherwise amenable to treatment with our products, or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and our business. For example, we are developing our leading product candidate, EYP-1901, for the treatment of wet AMD. Although we believe wet AMD is a common condition and a leading cause of vision loss for people age 50 and older, our estimates of the potential market opportunity for EYP-1901 may be incorrect.

If any of our products have newly discovered or developed safety problems, our business would be seriously harmed.

All of our approved products are and will be subject to continued oversight by the FDA or other foreign regulatory bodies, and we cannot assure you that newly discovered or developed safety issues will not arise. Although we have observedthere were no material safety issues to date,reported EYP-1901-related ocular or systematic serious adverse events (SAEs) in our Phase 2 clinical data, we cannot rule out that issues may arise in the future. For example, with the use of any newly marketed drug by a wider patient population, serious adverse events may occur from time to time that initially do not appear to relate to the drug itself. If such events are subsequently associated with the drug, or if any other safety issue emerges, we or our collaboration partners may voluntarily, or FDA or other regulatory authorities may require that we suspend or cease marketing of our approved products, or modify how we or they market our approved products. In addition, newly discovered safety issues may subject us to substantial potential liabilities and adversely affect our financial condition and business.

The Affordable Care Act and any changes in healthcare laws may increase the difficulty and cost for us to commercialize our approved products in the U.S. and affect the prices we may obtain.

The U.S. and state governments have enacted and proposed legislative and regulatory changes affecting the healthcare system that could affect our ability to profitably sell our approved products, prevent or delay marketing of our other product candidates and restrict or regulate post-approval activities. The U.S. and state governments also have shown significant interest in implementing cost-containment programs to limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement, and requirements for substitution of generic products for branded prescription products.

For example, the Affordable Care Act was intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry, and impose additional health policy reforms.

Among the provisions of the Affordable Care Act that have been implemented since enactment and are of importance to the commercialization of our approved productsproduct candidates in the U.S. are the following:

50

Certain provisions of the Affordable Care Act have been subject to judicial challenges as well as efforts to modify them or to alter their interpretation or implementation. For example, Congress eliminated starting January 1, 2019, the tax penalty for not complying with the Affordable Care Act’s individual mandate to carry health insurance Further, the Bipartisan Budget Act of 2018, among other things, amended the Medicare statute to reduce the coverage gap in most Medicare drugs plans, commonly known as the “donut hole,” by raising the required manufacturer point-of-sale discount from 50% to 70% off the negotiated price (the IRA sunsets the coverage gap discount program effective as of January 1, 2019.2025). Additional legislative changes, regulatory changes, and judicial challenges related to the Affordable Care Act remain possible. It is unclear how the Affordable Care Act and its implementation, as well as efforts to modify or invalidate the Affordable Care Act, or portions thereof or its implementation, will affect our business, financial condition, and results of operations. It is possible that the Affordable Care Act, as currently enacted or as it may be amended in the future, and other healthcare reform measures, including those that may be adopted in the future, could have a material adverse effect on our industry generally and on our ability to maintain or increase sales ofsuccessfully commercialize our approved products in the U.S. or to continue to successfully commercializeproduct candidates in the U.S.

We also expect that the Affordable Care Act, as well as other healthcare reform measures that have been adopted and that may be adopted in the future, may result in more rigorous coverage criteria and additional downward pressure on the price that we receive for our approved products in the U.S., and could seriously harm our future revenues. Any reduction in reimbursement from Medicare, Medicaid, or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenues, attain profitability, or successfully commercialize our approved products in the U.S.

There has been increasing legislative, regulatory, and enforcement interest in the United States with respect to drug pricing and

marketing practices. For example, in November 2020, the OIG issued a Special Fraud Alert to highlight certain inherent fraud and abuse risks associated with speaker fees, honorariums and expenses paid by pharmaceutical and medical device companies to healthcare professionals participating in company-sponsored events. The Special Fraud Alert sent a clear signal that speaker programs will be subject to potentially heightened enforcement scrutiny.

The Inflation Reduction Act of 2022 and other changes in healthcare law may impact the prices we are able to obtain for our products and our obligations to make payments to the government.

At both the federal and state level, legislatures are increasingly passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints. For example, the IRA includes a number of provisions that impact the pricing of pharmaceutical products. Among the provisions of the IRA that are important to our commercialized products are the following:

Civil monetary penalties (CMPs) could accrue for a failure to comply with certain drug price negotiation program, inflation rebate program, or Part D manufacturer discount program requirements. In addition, excise taxes could accrue for a failure to comply with certain drug price negotiation program requirements.

With respect to the drug price negotiation program, if any of our products were selected for negotiation and, as a result, a “maximum fair price” for such product were set, our Medicare revenue would materially decrease, and our Medicaid drug rebate program rebate and 340B drug pricing program liability would materially increase in addition. We anticipate imposition of a maximum fair price also would generate downward pricing pressure in the commercial market. As we anticipate that CMS’s implementation of the drug price negotiation program will evolve, and that there will be related legislative, administrative, and legal developments, our understanding of whether our products are likely to be selected for negotiation under this program, and whether they may be subject to additional downward pricing pressure, is likely to evolve as well, which could impact our understanding of our business and financial condition.

With respect to the inflation rebate programs, we have at times increased the price of certain of our products. We may need to make similar price adjustments to our products in the future and cannot guarantee that such price adjustments will not trigger an inflation rebate, which could negatively affect our business. A manufacturer that does not timely pay a rebate is subject to a CMP in an amount at least equal to 125 percent of the rebate amount.

With respect to the Medicare Part D benefit redesign, we participate in the Medicare Part D program and thus expect to participate in the new Part D manufacturer discount program starting in 2025. Changes to the manufacturer discount program could change our overall discount liability under the Part D program, as participating manufacturers, as a general matter, will be required to offer discounts on the negotiated price of a drug on a larger universe of units but at a lower discount rate. Reductions in patient out of pocket spending could lead to an improvement in patient medication adherence and overall Part D utilization. It is unclear how these changes will affect our business as a whole, and whether they will have an overall positive or negative impact. In addition, under the program, manufacturers that fail to provide a discounted price for an applicable drug can be subject to a CMP equal to 1.25 percent times the discount that the manufacturer should have paid under the program agreement.

We anticipate that there will be additional legislative and regulatory reforms that seek to address drug pricing in the U.S. As such, we expect the impact of, not only the IRA, but also all other such public policies on our business to evolve in ways that we cannot fully anticipate.

Patient assistance programs for pharmaceutical products have come under increasing scrutiny by governments, legislative bodies and enforcement agencies. These activities may result in actions that have the effect of reducing prices or demand for our products, harming our business or reputation, or subjecting us to fines or penalties.

We sponsorpreviously sponsored patient assistance programs, which arewere available to qualified patients for our products, including insurance premium and copay assistance programs. We also makemade donations to third-party charities that provide such assistance. Recently, there has been enhanced scrutiny of such company-sponsored programs and services. If we, our vendors or donation recipients, are deemed to have failed to comply with relevant laws, regulations or government guidance in any of these areas, we could be subject to criminal and civil sanctions, including significant fines, civil monetary penalties and exclusion from participation in government healthcare programs, including Medicare and Medicaid, and burdensome remediation measures. Actions could also be brought against executives overseeing our business or other employees.

It is possible that any actions taken by the Department of Justice (DOJ) as a result of this industry-wide inquiry could reduce demand for our products and/or reduce coverage of our products, including by federal and state health care programs such as Medicare and Medicaid. If any or all of these events occur, our business, prospects and stock price could be materially and adversely affected.

51

If competitive products are more effective, have fewer side effects, are more effectively marketed and/or cost less than our products or product candidates, or receive regulatory approval or reach the market earlier, our product candidates may not be approved and our products or product candidates may not achieve the sales we anticipate and could be rendered noncompetitive or obsolete.

We believe that pharmaceutical, drug delivery and biotechnology companies, research organizations, governmental entities, universities, hospitals, other nonprofit organizations, and individual scientists are seeking to develop drugs, therapies, products, approaches or methods to treat our targeted diseases or their underlying causes. For our targeted diseases, competitors have alternate therapies that are already commercialized or are in various stages of development, ranging from discovery to advanced clinical trials. Any of these drugs, therapies, products, approaches, or methods may receive government approval or gain market acceptance more rapidly than our products and product candidates, may offer therapeutic or cost advantages, or may more effectively treat our targeted diseases or their underlying causes, which could result in our product candidates not being approved, reduce demand for our products and product candidates or render them noncompetitive or obsolete.

Many of our competitors and potential competitors for our leading product candidate, EYP-1901, and our commercialized products have substantially greater financial, technological, research and development, marketing, and personnel resources than we

do. Our competitors may succeed in developing alternate technologies and products that, in comparison to the products or product candidates we have, and are seeking to, develop:

Many of these competitors have greater experience in developing products, conducting clinical trials, obtaining regulatory approvals or clearances, and manufacturing and marketing products than we do.

DEXYCU® is an intraocular suspension that delivers dexamethasone, a corticosteroid that is associated with certain adverse side effects in the eye, which may affect the success of DEXYCU® for the treatment of post-operative inflammation.

DEXYCU® is an intraocular suspension that delivers dexamethasone, a corticosteroid, which is associated with certain adverse side effects in the eye. The safety analyses from DEXYCU’sDEXYCU®’s clinical trials revealed that the most commonly reported adverse reactions were increases in intraocular pressure (IOP), corneal edema and iritis, a type of uveitis affecting the front of the eye. These side effects may adversely affect sales of DEXYCU.DEXYCU®.

If the FDA or other applicable regulatory authorities approve generic products that compete with any of our products or product candidates, it could reduce ourthe future sales of those products orour product candidates.

In the U.S., after an NDA is approved, the product generally becomes a “listed drug” which can, in turn, be relied upon by potential competitors in support of approval of an ANDA. The Federal Food, Drug, and Cosmetic Act, FDA regulations, and other applicable regulations and policies provide incentives to manufacturers to create generic, non-infringing versions of a drug to facilitate the approval of an ANDA. These manufacturers might show that their product has the same active ingredients, dosage form, strength, route of administration, conditions of use, and labeling as our product candidate and might conduct a relatively inexpensive study to demonstrate that the generic product is absorbed in the body at the same rate and to the same extent as, or is bioequivalent to, our product. These generic equivalents would be significantly less costly than ours to bring to market, and companies that produce generic equivalents are generally able to offer their products at lower prices. Thus, after the introduction of a generic competitor, a significant percentage of the sales of any branded product are typically lost to the generic product. Accordingly, competition from generic equivalents to our products would substantially limit our ability to generate revenues and therefore to obtain a return on the investments we have made in our products.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit manufacturing or commercialization of YUTIQ® and DEXYCU®, and any other product candidates that we may develop and commercialize, including EYP-1901.

We face the risk of product liability exposure as we commercializemanufacture YUTIQ® and DEXYCU® for our commercialization partners and other product candidates that we may develop and commercialize. We also may face product liability claims from patients who are treated with any of our product candidates in clinical trials. If we cannot successfully defend ourselves against claims that our products or product candidates caused injuries, we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

52

We currently carry product liability insurance with coverage up to $30.0 million in the aggregate, with a per incident limit of $30.0 million, which may not be adequate to cover all liabilities that we may incur. Further, we may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise. Our inability to maintain sufficient product liability insurance at an acceptable cost could prevent or inhibit the commercializationmanufacture of YUTIQ® and DEXYCU,our ability to meet our

obligations to our commercialization partners, or could prevent or inhibit the development and commercialization of our other product candidates, including EYP-1901.

Additionally, any agreements we have entered into, or we may enter intointo. in the future with collaborators in connection with the development or commercialization of YUTIQ, DEXYCU, EYP-1901 or any of our other product candidates, may entitle us to indemnification against product liability losses, but such indemnification may not be available or adequate should any claim arise. In addition, several of our agreements require us to indemnify third parties and these indemnification obligations may exceed the coverage under our product liability insurance policy.

RISKS RELATED TO OUR INTELLECTUAL PROPERTY

If we are unable to protect our intellectual property rights or if our intellectual property rights are inadequate to protect our product candidates, our competitors could develop and commercialize technology and products similar to ours, and our competitive position could be harmed.

Our commercial success will depend in large part on our ability to obtain and maintain patent and other intellectual property protection in the U.S. and other countries with respect to our proprietary technology and products. We rely on trade secret, patent, copyright and trademark laws, and confidentiality and other agreements with employees and third parties, all of which offer only limited protection. We seek patent protection for many different aspects of our product candidates, including their compositions, their methods of use, processes for their manufacture, and any other aspects that we deem to be commercially important to the development of our business.

The patent prosecution process is expensive and time-consuming, and we and any licensors and licensees may not be able to apply for or prosecute patents on certain aspects of our product candidates or delivery technologies at a reasonable cost, in a timely fashion, or at all. For technology licensed to third parties, we may not have the right to control the preparation, filing and/or prosecution of the corresponding patent applications, or to maintain patent rights corresponding to such technology. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. It is also possible that we, or any licensors or licensees, will fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, such as with respect to proper priority claims, inventorship, claim scope, or patent term adjustments. If any licensors or licensees are not fully cooperative or disagree with us as to the prosecution, maintenance, or enforcement of any patent rights, such patent rights could be compromised, and we might not be able to prevent third parties from making, using, and selling competing products. If there are material defects in the form or preparation of our patents or patent applications, such patents or applications may be invalid or unenforceable. Moreover, our competitors may independently develop equivalent knowledge, methods, and know-how. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business, financial condition, and operating results.

The patent positions of pharmaceutical companies generally are highly uncertain, involve complex legal and factual questions and have in recent years been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of any patents that issue, are highly uncertain. For example, recent changes to the patent laws of the U.S. provide additional procedures for third parties to challenge the validity of issued patents. Under the Leahy-Smith America Invents Act, or AIA, which was signed into law on September 16, 2011, patents issued from applications with an effective filing date after March 15, 2013, may be challenged by third parties using the post-grant review procedure which allows challenges for a number of reasons, including prior art, sufficiency of disclosure, and subject matter eligibility. Under the AIA, patents may also be challenged under the inter partes review procedure. Inter partes review provides a mechanism by which any third party may challenge the validity of any issued U.S.

53

Patent in the USPTO on the basis of prior art. Because of a lower evidentiary standard necessary to invalidate a patent claim in USPTO proceedings as compared to the evidentiary standard relied on in U.S. federal court, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action.

With respect to foreign jurisdictions, the laws of foreign countries may not protect our rights to the same extent as the laws of the U.S. or vice versa. For example, European patent law restricts the patentability of methods of treatment of the human body more than U.S. law does. Also, patents granted by the European Patent Office may be opposed by any person within nine months from the publication of their grant.

Our patents and patent applications, even if unchallenged by a third party, may not adequately protect our intellectual property or prevent others from designing around our claims. The steps we have taken to protect our proprietary rights may not be adequate to

preclude misappropriation of our proprietary information or infringement of our intellectual property rights, both inside and outside the U.S. Further, the examination process may require us to narrow the claims of pending patent applications, which may limit the scope of patent protection that may be obtained if these applications issue. The rights that may be granted under future issued patents may not provide us with the proprietary protection or competitive advantages we are seeking. If we are unable to obtain and maintain patent protection for our technology and products, or if the scope of the patent protection obtained is not sufficient, our competitors could develop and commercialize technology and products similar or superior to ours, and our ability to successfully commercialize our technology and productsproduct candidates may be impaired.

As of February 28, 2023,March 1, 2024, we hadowned proprietary know-how and several patents and pending applications, including patents and pending applications covering our Durasert®, VerisomeEYP-1901,VERISOME® and other technologies. With respect to these patent rights, we do not know whether any of our patent applications will result in issued patents or, if any of our patent applications do issue, whether such patents will protect our technology in whole or in part, or whether such patents will effectively prevent others from commercializing competitive technologies and products. There is no guarantee that any of our issued or granted patents will not later be found invalid or unenforceable. Furthermore, since patent applications in the U.S. and most other countries are confidential for a period of time after filing, we cannot be certain that we were the first to either (i) file any patent application related to our product candidates or (ii) invent any of the inventions claimed in our patents or patent applications. For applications with an effective filing date before March 16, 2013, or patents issuing from such applications, an interference proceeding can be provoked by a third party or instituted by the USPTO to determine who was the first to invent any of the subject matter covered by the patent claims of our applications and patents. As of March 16, 2013, the U.S. transitioned to a “first-to-file” system for deciding which party should be granted a patent when two or more patent applications are filed by different parties claiming the same invention. A third party that files a patent application in the USPTO before us could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by the third party. This will require us to be cognizant going forward of the time from invention to filing of a patent application. The change to “first-to-file” from “first-to-invent” is one of the changes to the patent laws of the U.S. resulting from the AIA.

Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the U.S. and other jurisdictions are typically not published until 18 months after filing or in some cases not at all, until they are issued as a patent. Therefore, we cannot be certain that we were the first to make the inventions claimed in our pending patent applications, that we were the first to file for patent protection of such inventions, or that we have found all of the potentially relevant prior art relating to our patents and patent applications that could invalidate one or more of our patents or prevent one or more of our patent applications from issuing. Even if patents do successfully issue and even if such patents cover our product candidates, third parties may initiate oppositions, interferences, re-examinations, post-grant reviews, inter partes reviews, nullification or derivation actions in court or before patent offices or similar proceedings challenging the validity, enforceability, or scope of such patents, which may result in the patent claims being narrowed or invalidated. Furthermore, even if they are unchallenged, our patents and patent applications may not adequately protect our intellectual property, provide exclusivity for our product candidates, or prevent others from designing around our claims. Any of these outcomes could impair our ability to prevent competition from third parties.

Furthermore, the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may be challenged in the courts or patent offices in the U.S. and abroad. Such challenges may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and products.product candidates. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such product candidates might expire before or shortly after such product candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

54

We may become involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time consuming and unsuccessful.

Competitors may infringe our patents or the patents of any party from whom we may license patents from in the future. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. In a patent litigation in the U.S., defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or made a misleading statement during prosecution. The outcome following legal assertions of invalidity and unenforceability during patent litigation is unpredictable. A court may decide that a patent of ours or of any of our future licensors is not valid, or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. In addition, to the extent that we have to file patent litigation in a federal court against a U.S. patent holder, we would be required to initiate the proceeding in the state of incorporation or residency of such entity. With respect to the validity question, for example, we cannot be certain that no invalidating

prior art exists. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated, found unenforceable, or interpreted narrowly, and it could put our patent applications at risk of not issuing. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on one or more of our products. Such a loss of patent protection could compromise our ability to pursue our business strategy.

As noted above, interference proceedings brought by the USPTO for applications with an effective filing date before March 16, 2013, or for patents issuing from such applications may be necessary to determine the priority of inventions with respect to our patents and patent applications or those of our collaborators or licensors. An unfavorable outcome could require us to cease using the technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if a prevailing party does not offer us a license on terms that are acceptable to us. Litigation or interference proceedings may fail and, even if successful, may result in substantial costs and distraction of our management and other employees. We may not be able to prevent, alone or with any of our future licensors, misappropriation of our proprietary rights, particularly in countries where the laws may not protect those rights as fully as in the U.S. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock.

Moreover, we may be subject to a third-party pre-issuance submission of prior art to the USPTO or other foreign patent offices, or become involved in opposition, derivation, reexamination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could invalidate or reduce the scope of, our patent rights, allow third parties to commercialize our technology or drugs and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize drugs without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop, or commercialize current or future product candidates.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting, and defending patents on our product candidates throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the U.S. may be less extensive than those in the U.S. In addition, the laws and practices of some foreign countries do not protect intellectual property rights, especially those relating to life sciences, to the same extent as federal and state laws in the U.S. For example, novel formulations of drugs and manufacturing processes may not be patentable in certain jurisdictions, and the requirements for patentability may differ in certain countries, particularly developing countries. Also, some foreign countries, including EU countries, India, Japan, and China, have compulsory licensing laws under which a patent owner may be compelled under certain circumstances to grant licenses to third parties. Consequently, we may have limited remedies if patents are infringed or if we are compelled to grant a license to a third party, and we may not be able to prevent third parties from practicing our inventions in all countries outside the U.S., or from selling or importing products made using our inventions into or within the U.S. or other jurisdictions. This could limit our potential revenue opportunities. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products, and may export otherwise infringing products to territories where we have patent protection, but where enforcement is not as strong as that in the U.S. These, these products may compete with our productsproduct candidates in jurisdictions where we do not have any issued patents and our patent claims or other intellectual property rights may not be effective or sufficient to prevent them from competing with us in these jurisdictions. Accordingly, our efforts to enforce intellectual property rights around the world may be inadequate to obtain a significant commercial

55

advantage from our intellectual property. We may not prevail in any lawsuits that we initiate in these foreign countries and the damages or other remedies awarded, if any, may not be commercially meaningful.

Further, the complexity and uncertainty of European patent laws have increased in recent years. In Europe, a new unitary patent system will likely be introduced by the end of 2023, which would significantly impact European patents, including those granted before the introduction of such a system.came into force on June 1, 2023. Under the unitary patent system, European applications will soon have the option, upon grant of a European patent, of becoming a Unitary Patent may be elected, which will be affected in the EU member states that have ratified the Unitary Patent Court (UPC). Agreement and will be subject to the jurisdiction of the Unitary Patent Court (UPC).UPC. As the UPC is a new court system, there is no precedent for the court, increasing the uncertainty of any litigation. Patents granted before the implementation of the UPC will have the option of opting out of the jurisdiction of the UPC and remaining as national patents in the UPC countries. Patents that remain under the jurisdiction of the UPC will be potentially vulnerable to a single UPC-based revocation challenge that, if successful, could invalidate the patent in all countries who are signatories tohave ratified the UPC. We cannot predict with certainty the long-term effects of any potential changes.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and applications are required to be paid to the USPTO and various governmental patent agencies outside of the U.S. in several stages over the lifetime of the patents and applications. The USPTO and various non-U.S. governmental patent agencies require compliance with a number of procedural, documentary, fee payment, and other similar provisions during the patent application process and after a patent has issued. There are situations in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction.

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which could be uncertain and could harm our business.

Our commercial success depends upon our ability, and the ability of our partners and collaborators, to develop, manufacture, market, and sell our products and product candidates, if approved, and use our proprietary technologies without infringing the proprietary rights of third parties. Although our product candidates are in pre-clinical studies and clinical trials, we believe that the use of our product candidates in these pre-clinical studies and clinical trials falls within the scope of the exemptions provided by 35 U.S.C. Section 271(e) in the U.S., which exempts from patent infringement liability activities reasonably related to the development and submission of information to the FDA. As our other product candidates progress toward commercialization, the possibility of a patent infringement claim against us increases. Accordingly, we may invest significant time and expense in the development of our product candidates only to be subject to significant delay and expensive and time-consuming patent litigation before our product candidates may be commercialized. There can be no assurance that our products or product candidates do not infringe other parties’ patents or other proprietary rights, and competitors or other parties may assert that we infringe their proprietary rights in any event.

There is considerable intellectual property litigation in the biotechnology and pharmaceutical industries. We may become party to, or threatened with, future adversarial proceedings or litigation regarding intellectual property rights with respect to our product candidates, including interference or derivation proceedings before the USPTO. Numerous U.S. and foreign issued patents and pending patent applications owned by third parties exist in the fields in which we are developing our product candidates. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future.

If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue commercializing our products or product candidates. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if a license can be obtained on acceptable terms, the rights may be non-exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us. If we fail to obtain a required license, we may be unable to effectively market products or product candidates based on our technology, which could limit our ability to generate revenues or achieve profitability and possibly prevent us from generating revenues sufficient to sustain our operations. Alternatively, we may need to redesign our infringing products, which may be impossible or require substantial time and monetary expenditure. Under certain circumstances, we could be forced, including by court order, to cease commercializing our products or product candidates. In addition, in any such proceeding or litigation, we could be found liable for substantial monetary damages, potentially including treble damages and attorneys’ fees, if we are found to have willfully infringed. A finding of infringement could prevent us from commercializing our products or product candidates or force us to cease some of our business operations, which could harm our business. Any claims by third parties that we have misappropriated their confidential information or trade secrets could have a similar negative impact on our business.

56

The cost to us in defending or initiating any litigation or other proceeding relating to patent or other proprietary rights, even if resolved in our favor, could be substantial, and litigation would divert our management’s attention. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could compromise our commercialization efforts, delay our research and development efforts and limit our ability to continue our operations. There could also be public announcements of the results of the hearing, motions, or other interim proceedings or developments. If securities analysts or investors perceive those results to be negative, it could cause the price of shares of our common stock to decline.

Our competitors may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner.

Our competitors may seek approval to market their own products that are the same as, similar to or otherwise competitive with our products or product candidates. In these circumstances, we may need to defend or assert our patents by various means, including filing lawsuits alleging patent infringement requiring us to engage in complex, lengthy and costly litigation, or other proceedings. In any of these types of proceedings, a court or government agency with jurisdiction may find our patents invalid, unenforceable or not

infringed. We may also fail to identify patentable aspects of our research and development before it is too late to obtain patent protection. Even if we have valid and enforceable patents, these patents still may not provide protection against competing products or processes sufficient to achieve our business objectives.

Changes in either U.S. or foreign patent law or interpretation of such laws could diminish the value of patents in general, thereby impairing our ability to protect our products or product candidates.

As is the case with other pharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the pharmaceutical industry involve both technological and legal complexity, and it therefore is costly, time-consuming and inherently uncertain. As noted above, the AIA has significantly changed U.S. patent law. In addition to transitioning from a “first-to-invent” to “first-to-file” system, the AIA also limits where a patentee may file a patent infringement suit and provides opportunities for third parties to challenge issued patents in the USPTO via post-grant review or inter partes review, for example. All of our U.S. patents, even those issued before March 16, 2013, may be challenged by a third party seeking to institute inter partes review.

Depending on decisions by the U.S. Congress, the federal courts, the USPTO, or similar authorities in foreign jurisdictions, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

We may be subject to claims asserting that our employees, consultants, independent contractors and advisors have wrongfully used or disclosed confidential information and/or alleged trade secrets of their current or former employers or claims asserting ownership of what we regard as our own intellectual property.

Although we try to ensure that our employees, consultants, independent contractors and advisors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these individuals or we have inadvertently or otherwise used or disclosed confidential information and/or intellectual property, including trade secrets or other proprietary information, of the companies that any such individual currently or formerly worked for or provided services to. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to our business.

In addition, while we require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property.

Intellectual property rights do not prevent all potential threats to competitive advantages we may have.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and intellectual property rights may not adequately protect our business or permit us to maintain our competitive advantage.

57

The following examples are illustrative:

Should any of these events occur, they could significantly harm our business, financial condition, results of operations and prospects.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patent protection for certain aspects of our product candidates and technologies, we also consider trade secrets, including confidential and unpatented know-how, important to the maintenance of our competitive position. We protect trade secrets and confidential and unpatented know-how, in part, by customarily entering into non-disclosure and confidentiality agreements with parties who have access to such knowledge, such as our employees, outside scientific and commercial collaborators, CROs, CMOs, consultants, advisors, and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants that obligate them to maintain confidentiality and assign their inventions to us. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. In addition, our trade secrets may otherwise become known, including through a potential cybersecurity breach, or may be independently developed by competitors.

Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts in the U.S. and certain foreign jurisdictions are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed.

If our trademarks are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

We expect to rely on trademarks as one means to distinguish any of our approved products from the products of our competitors. We have received registrations for EYEPOINT®, YUTIQ®, DEXYCU®, DELIVERING INNOVATION TO THE EYE® and, DURASERT®. The Verisome,and WITH AN EYE ON PATIENTS® technology is exclusively licensed to us by Ramscor, Inc and the Verisome® mark is owned by Ramscor, Inc. Our and our licensees’ trademarks may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. For our trademarks, we have entered into a co-existence agreement with Sun Pharma and a settlement agreement with Merck allowing continued, though somewhat limited, use of two of our marks. If we are unable to establish name recognition based on our trademarks, we may not be able to compete effectively.

RISKS RELATED TO OUR RELIANCE ON THIRD PARTIES

The development and commercialization of our lead product candidate, EYP-1901, is dependent on intellectual property we license from Equinox Science and APIactive pharmaceutical ingredient (API) supply of vorolanib. If we breach our agreement with Equinox Science, or the agreement is terminated, we could lose license rights that are material to our business.

Pursuant to our license agreement with Equinox, we acquired exclusive rights to patents, patent applications and know-how owned or controlled by Equinox relating to the compound vorolanib, a tyrosine kinase inhibitor. Our lead product candidate, EYP-1901, utilizes vorolanib in combination with our proprietary Durasert E™ sustained release technology. At present, Betta, an affiliate of Equinox also provides us withis a provider of the API supply of vorolanib to support our clinical trials. Our license agreement with Equinox imposes various development, regulatory, commercial, financial, and other obligations on us. If we fail to comply with our obligations under the agreement with Equinox, or otherwise materially breach the agreement with Equinox, and fail to remedy such failure or cure such breach within 90 days, Equinox will have the right to terminate the agreement. If our agreement with Equinox is terminated by Equinox for our uncured material breach, we would lose our license and all rights to the use of vorolanib, from Equinox, for EYP-1901. The loss of the license from Equinox wouldcould prevent us from developing and commercializing EYP-1901 and could subject us to claims of breach of contract and patent infringement from Equinox if any continued research, development, manufacture or commercialization of EYP-1901 is covered by the affected patents. Accordingly, the loss of our license from Equinox would materially harm our business.

The development of our lead product candidate, EYP-1901, is dependent on our supply of its active pharmaceutical ingredient (API)API vorolanib, which we source from third-parties. If any manufacturer or partner we rely upon fails to supply vorolanib in the amounts we require on a timely basis, or fails to comply with stringent regulations applicable to pharmaceutical drug manufacturers, we may be unable to meet demand for our products and may lose potential revenues.

We currently source vorolanib, the API in EYP-1901, from Betta, Pharmaceuticals and have plans to source vorolanib from additional third parties, and we also source various raw materials and components for both EYP-1901 and its injector from third-party vendors. We are also working with a third party manufacturer to develop the process for manufacturing vorolanib and become the U.S. supplier of vorolanib for use in EYP-1901. We do not manufacture any of our supply of vorolanib, and we do not currently plan to develop any capacity to do so. Our dependence upon third parties for the manufacture of our vorolanib could adversely affect our profit margins or our ability to develop and deliver products on a timely and competitive basis. If for any reason we are unable to obtain or retain third-party manufacturers on commercially acceptable terms, we may not be able to sell EYP-1901 as planned. Furthermore, if we encounter delays or difficulties with manufacturers in producing vorolanib, the distribution, marketing and subsequent sales of EYP-1901 could be adversely affected. A long-term inability to meet demand for our products could result in impairment of our brands overall future and the carrying value of the assets associated with our brands. The recent COVID-19 pandemic has and may continue to create issues for our third party-manufacturers and introduce delays in our manufacturing process.

Due to the loss of pass-through related separate payment of DEXYCU as of January 1, 2023, we agreed to terminate our ongoing Commercial Alliance Agreement with ImprimisRx to co-promote DEXYCU, which could also have a material adverse effect on our business, financial condition and results of operations due to a reduction of cash flow associated with DEXYCU.

In August 2020, to complement and augment the efforts of our internal sales team for DEXYCU, we entered into a Commercial Alliance Agreement, effective as of August 1, 2020 and amended as of November 12, 2020 (the Commercial Alliance Agreement) with ImprimisRx for the sale of DEXYCU to its customers. On December 6, 2021, we entered into a letter agreement (the Letter Agreement) to expand the commercial alliance previously established by the parties pursuant to the Commercial Alliance Agreement. During the two-year term of the Letter Agreement, ImprimisRx assumed full responsibility for the sales and marketing of DEXYCU and absorbed the majority of our DEXYCU commercial organization. We continued to recognize net product revenue and maintain manufacturing and distribution responsibilities for DEXYCU along with non-sales related regulatory compliance responsibilities. We paid ImprimisRx a commission based on the net sales of DEXYCU in the U.S. and will retain control over all regulatory approvals and commercial rights for DEXYCU. The Letter Agreement was effective as of January 1, 2022 and was to continue through December 31, 2023, unless such term is amended by mutual agreement of the parties or terminated in accordance therewith.

The Letter Agreement provided that either party may terminate the Commercial Alliance Agreement upon 30 days’ prior written notice in the event DEXYCU ceases to have Medicare Part B “pass-through” payment status for a period of not less than six months. ImprimisRx had an additional right to terminate the Letter Agreement with 30 days’ written notice if (i) a proposed or final Hospital Outpatient Prospective Payment System (HOPPS) rule issued by CMS during calendar year 2022 did not contain an extension of the pass-through payment period for DEXYCU beyond December 31, 2022, and (ii) we had not otherwise waived any minimum sales for a respective quarterly period.

59

We entered into (the Termination Agreement) with ImprimisRx on October 7, 2022, pursuant to which we and ImprimisRx agreed (a) that ImprimisRx would continue to support the sales and marketing of DEXYCU through the fourth quarter of 2022, consistent with ImprimisRx’s level of effort during the January through June 2022 period, (b) decrease the required minimum quarterly sales levels based on DEXYCU unit demand for the fourth quarter of 2022, and (c) terminate the previously entered into Commercial Alliance Agreement, made effective as of August 1, 2020, as modified by the Agreements, effective January 1, 2023 due to the loss of pass-through related separate payment of DEXYCU. The December 2022 termination of our arrangement with ImprimisRx could have a material adverse effect on our business, financial condition, results of operations and induce a reduction of cash flow.

If we encounter issues with our CMOs or suppliers, we may need to qualify alternative manufacturers or suppliers, which could impair our ability to sufficiently and timely manufacture and supply DEXYCU.

We currently depend on CMOs and suppliers for DEXYCU. Although we could obtain the drug product and other components for DEXYCU from other CMOs and suppliers, we would need to qualify and obtain FDA approval for such CMOs or suppliers as alternative sources, which could be costly and cause significant delays. In addition, the manufacturer of the drug product in DEXYCU conducts its manufacturing operations for us at a single facility. Unless and until we qualify additional facilities, we may face limitations in our ability to respond to manufacturing issues. For example, if regulatory, manufacturing or other problems require this manufacturer to discontinue production at its facility, or if the equipment used for the production of the drug product in this facility is significantly damaged or destroyed by fire, flood, earthquake, power loss or similar events, the ability of such manufacturer to manufacture DEXYCU may be significantly impaired. In the event that this party suffers a temporary or protracted loss of its materials, facility or equipment, we would still be required to obtain FDA approval to qualify a new manufacturer as an alternate manufacturer for the drug product before any drug product manufactured by such manufacturer could be sold or used. Any production shortfall that impairs the supply of DEXYCU could adversely affect our ability to satisfy demand for DEXYCU, which could have a material adverse effect on our product sales, results of operations and financial condition.

The Pandemic may also have an adverse impact on our CMOs or suppliers as a result of employees or other key personnel becoming infected, preventive and precautionary measures that governments or such third parties are taking, such as social distancing, quarantines, and other restrictions, and shortages of supplies necessary for the manufacture of DEXYCU. Any of these circumstances could adversely impact the ability of third parties on which we rely to manufacture and distribute adequate volumes of DEXYCU.

We use our own facility for the manufacturing of YUTIQ and rely on third party suppliers for key components, and any disruptions to our suppliers’ operations could adversely affect YUTIQ’s commercial viability.

We currently manufacture commercial supplies of YUTIQ ourselves at our Watertown, MA facility and rely on third party suppliers for key components of YUTIQ. We have, and will continue, to perform extensive audits of our suppliers, vendors and contract laboratories. The cGMP requirements govern, among other things, recordkeeping, production processes and controls, personnel and quality control. To ensure that we continue to meet these requirements, we have and will continue to expend significant time, money and effort.

The commercial manufacture of medical products is complex and requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of medical products often encounter difficulties in production, particularly in scaling out and validating initial production and ensuring the absence of contamination. These problems include difficulties with production costs and yields, quality control, including stability of the product, quality assurance testing, operator error, shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations. We cannot assure you that any issue relating to the manufacture of YUTIQ will not occur in the future.

The FDA also may, at any time following approval of a product for sale, audit our manufacturing facilities. If any such inspection or audit identifies a failure to comply with applicable regulations or if a violation of our product specifications or applicable regulation occurs independent of such an inspection or audit, FDA may issue a Form FDA-483 and/or an untitled or warning letter, or we or the FDA may require remedial measures that may be costly and/or time consuming for us to implement and that may include the temporary or permanent suspension of commercial sales, recalls, market withdrawals, seizures or the temporary or permanent closure of a facility. For example, we received a Form FDA-483 at the conclusion of an FDA inspection in September 2021. Although we believe we have successfully addressed and responded to FDA concerning those observations, FDA has not yet determined whether our facility will remain classified as Official Action Indicated (OAI), which could lead to enforcement action or affect the approval of an application. As of the date of this filing, the FDA has not yet posted the September 2021 inspection in the FDA Inspections database. We are monitoring the database closely, as it is expected that the inspection should be posted soon. The FDA has cited issues related to the Pandemic as a reason for the delay in much of their inspection activity. Any such remedial measures imposed upon us could materially harm our business.

60

In addition, although we could contract with other third parties to manufacture YUTIQ, we would need to qualify and obtain FDA approval for a contract manufacturer or supplier as an alternative source for YUTIQ, which could be costly and cause significant delays.

Our YUTIQ manufacturing operations depend on our Watertown, MA facility. If this facility is destroyed or is out of operation for a substantial period of time, our business may be adversely impacted.

We currently conduct our manufacturing operations related to YUTIQ in our facility located in Watertown, MA. If regulatory, manufacturing or other problems, including Pandemic-related impacts on our employees, require us to suspend or discontinue production at our Watertown, MA facility, we will not be able to have or maintain adequate commercial supply of YUTIQ, which would adversely impact our business. If the facility or the equipment in it is significantly damaged or destroyed by fire, flood, power loss or similar events, we may not be able to quickly or inexpensively replace our facility. In the event of a temporary or protracted loss of either facility or equipment, we might not be able to transfer manufacturing to a third party. Even if we could transfer manufacturing to a third party, the shift would likely be expensive and time-consuming, particularly since the new facility would need to comply with necessary regulatory requirements.

The Pandemic may also have an adverse impact on our manufacturing activities for YUTIQ as a result of employees or other key personnel becoming infected, preventive and precautionary measures that governments or such third parties are taking, such as social distancing, quarantines, and other restrictions, and shortages of supplies necessary for the manufacture of YUTIQ. Any of these circumstances could adversely impact our ability to manufacture and distribute adequate volumes of YUTIQ.

If third-party manufacturers, wholesalers and distributors fail to devote sufficient time and resources to DEXYCU or their performance is substandard, our product supply may be impacted.

Our reliance on a limited number of manufacturers, wholesalers and distributors exposes us to the following risks, any of which could limit commercial supply of our products, result in higher costs, or deprive us of potential product revenues:

Our reliance on third parties reduces our control over our development and commercialization activities but does not relieve us of our responsibility to ensure compliance with all required legal, regulatory and scientific standards. For example, the FDA and other regulatory authorities require that our product candidates and any products that we may eventually commercialize be manufactured according to cGMP and similar foreign standards. Any failure by our third-party manufacturers to comply with cGMP or failure to scale up manufacturing processes, including any failure to deliver sufficient quantities of product candidates in a timely manner, could lead to a delay in, or failure to obtain, regulatory approval of any of our product candidates or supply our commercial volume of DEXYCU. In addition, such failure could be the basis for the FDA to issue a warning or untitled letter, withdraw approvals for products previously granted to us, or take other regulatory or legal action, including recall or seizure, total or partial suspension of production, suspension of ongoing clinical trials, refusal to approve pending applications or supplemental applications, detention or product, refusal to permit the import or export of products, injunction, imposing civil penalties or pursuing criminal prosecution.

If our CROs, vendors and investigators do not successfully carry out their responsibilities or if we lose our relationships with them, our development efforts with respect to our product candidates could be delayed.

We are dependent on CROs, vendors, and investigators for pre-clinical testing and clinical trials related to our product development programs, including for EYP-1901. These parties are not our employees, and we cannot control the amount or timing of resources that they devote to our programs. If they do not timely fulfill their responsibilities or if their performance is inadequate, the development and commercialization of our product candidates could be delayed. The parties with which we contract for execution of clinical trials play a significant role in the conduct of the trials and the subsequent collection and analysis of data. Their failure to meet their obligations could adversely affect clinical development of our product candidates. In addition, if we or our CROs fail to comply

61

with applicable current Good Clinical Practices (GCP), the clinical data generated in our clinical trials may be deemed unreliable and the FDA may require us to perform additional clinical trials before approving any marketing applications. Upon inspection, the FDA may determine that our clinical trials did not comply with GCP.

Switching or adding additional CROs involves additional cost and requires management time and focus. Identifying, qualifying and managing performance of third-party service providers can be difficult, time-consuming and cause delays in our development programs. In addition, there is a natural transition period when a new CRO commences work and the new CRO may not provide the same type or level of services as the original provider. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects. If any of our relationships with our CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. As a result, delays may occur, which can materially impact our ability to meet our desired clinical development timelines.

Because we have relied on third parties, our internal capacity to perform these functions is limited. Outsourcing these functions involves risks that third parties may not perform to our standards, may not produce results in a timely manner or may fail to perform at all. In addition, the use of third-party service providers requires us to disclose our proprietary information to these parties, which could increase the risk that this information will be misappropriated. We currently have a small number of employees, which limits the internal resources we have available to identify and monitor our third-party providers. To the extent we are unable to identify and successfully manage the performance of third-party service providers in the future, our ability to advance our product candidates through clinical trials will be compromised. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition, and prospects.

We use our own facility for the manufacturing of YUTIQ® and rely on third party suppliers for key components, and any disruptions to our suppliers’ operations could adversely affect YUTIQ®’s commercial viability.

Pursuant to our agreements with our commercialization partners, we currently manufacture commercial supplies of YUTIQ® ourselves at our Watertown, MA facility and rely on third party suppliers for key components of YUTIQ®. We have, and will continue, to perform extensive audits of our suppliers, vendors and contract laboratories. The cGMP requirements govern, among other things, recordkeeping, production processes and controls, personnel and quality control. To ensure that we continue to meet these requirements, we have and will continue to expend significant time, money, and effort.

In addition, although we could contract with other third parties to manufacture YUTIQ®, we would need to qualify and obtain FDA approval for a contract manufacturer or supplier as an alternative source for YUTIQ®, which could be costly and cause significant delays.

Our manufacturing operations currently depend on our Watertown, MA facility and we are currently developing an additional manufacturing facility in Northbridge, MA. If our Watertown location is destroyed or out of operation, or, if the Northbridge development is delayed for a substantial period of time, our business may be adversely impacted.

We currently conduct our manufacturing operations related to YUTIQ® in our facility located in Watertown, MA. If regulatory, manufacturing or other problems, require us to suspend or discontinue production at our Watertown, MA facility, we will not be able to have or maintain adequate commercial supply of YUTIQ®, which would adversely impact our business. If the facility or the equipment in it is significantly damaged or destroyed by fire, flood, power loss, or similar events, we may not be able to quickly or inexpensively replace our facility. In the event of a temporary or protracted loss of either facility or equipment, we might not be able to transfer manufacturing to a third party. Even if we could transfer manufacturing to a third party, the shift would likely be expensive and time-consuming, particularly since the new facility would need to comply with necessary regulatory requirements. On January 23, 2023, the Company entered into a lease agreement for its new standalone manufacturing facility, including office and lab space located at 600 Commerce Drive, Northbridge, Massachusetts. The facility will be Good Manufacturing Practice (GMP) compliant to meet U.S. FDA and European Medicines Agency (EMA) standards and support EYP-1901’s clinical supply and commercial readiness upon regulatory approval. In addition, the building will have the capacity and capabilities to support our commercial business and expanding pipeline. The new facility, customized for our requirements, is expected to be operational in the second half of 2024. If the new facility is delayed for a substantial period of time, then we may not be able to accelerate future production for EYP-1901, as well as support global demand for our U.S. FDA and China NMPA approved therapy, YUTIQ, as currently planned.

If we encounter issues with our CMOs or suppliers, we may need to qualify alternative manufacturers or suppliers, which could impair our ability to sufficiently and timely manufacture and supply DEXYCU®.

We currently depend on CMOs and suppliers for DEXYCU®. Although we could obtain the drug product and other components for DEXYCU® from other CMOs and suppliers, we would need to qualify and obtain FDA approval for such CMOs or suppliers as alternative sources, which could be costly and cause significant delays. In addition, the manufacturer of the drug product in DEXYCU® conducts its manufacturing operations for us at a single facility. Unless and until we qualify additional facilities, we may face limitations in our ability to respond to manufacturing issues. For example, if regulatory, manufacturing or other problems require this manufacturer to discontinue production at its facility, or if the equipment used for the production of the drug product in this facility is significantly damaged or destroyed by fire, flood, earthquake, power loss or similar events, the ability of such manufacturer to manufacture DEXYCU® may be significantly impaired. In the event that this party suffers a temporary or protracted loss of its materials, facility or equipment, we would still be required to obtain FDA approval to qualify a new manufacturer as an alternate manufacturer for the drug product before any drug product manufactured by such manufacturer could be sold or used. Any production shortfall that impairs the supply of DEXYCU® could adversely affect our ability to satisfy demand for DEXYCU®, which could have a material adverse effect on our product sales, results of operations and financial condition.

Our employees, collaborators, service providers, independent contractors, principal investigators, consultants, co-promotion partners, vendors and CROs may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk that our employees, collaborators, independent contractors, principal investigators, consultants, co-promotion partners, vendors, and CROs may engage in fraudulent or other illegal activity with respect to our business. Misconduct by these employees could include intentional, reckless and/or negligent conduct or unauthorized activity that violates:

In particular, sales, marketing, and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing, and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Misconduct by these parties could also involve individually identifiable information, including, without limitation, the improper use of information obtained in the course of clinical trials, or illegal misappropriation of drug product, which could result in regulatory sanctions and serious harm to our reputation. Any incidents or any other conduct that leads to an employee receiving an FDA debarment could result in a loss of business from third parties and severe reputational harm.

Although we have adopted a Code of Business Conduct to govern and deter such behaviors, it is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and curtailment of our operations.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK

The trading price of the shares of our common stock has been highly volatile, and purchasers of our common stock could incur substantial losses.

The price of our common stock is highly volatile and may be affected by developments directly affecting our business, as well as by developments out of our control or not specific to us. The pharmaceutical and biotechnology industries, in particular, and the stock market generally, are vulnerable to abrupt changes in investor sentiment. Prices of securities and trading volumes of companies in the pharmaceutical and biotechnology industries, including ours, can swing dramatically in ways unrelated to, or that bear a disproportionate relationship to, our performance. The price of our common stock and their trading volumes may fluctuate based on a number of factors including, but not limited to:

In addition, low trading volume in our common stock may increase their price volatility. Holders of our common stock may not be able to liquidate their positions at the desired time or price. Finally, we will need to continue to meet the listing requirements of Nasdaq including the minimum stock price, for our stock to continue to be traded on Nasdaq.

A small concentration of approximately ten stockholders beneficially own 63%65% of our total outstanding common stock, which gives certain stockholders significant control over matters subject to stockholder approval, which would prevent new investors from influencing significant corporate decisions.

Franklin Resources, EW Healthcare, RA Capital Management, Suvretta Capital Management, Ocumension, and Adage Capital shareholdersApproximately ten stockholders beneficially own an aggregate of over 63%65% of our outstanding shares of common stock, as of March 2, 2023.February 23, 2024. These stockholders have the ability to significantly influence the outcome of matters submitted to our stockholders for approval, including the election and removal of directors, and any merger, consolidation or sale of all or substantially all of our assets. In addition, the concentration of voting power in these certain stockholders may: (i) delay, defer or prevent a change in control; (ii) entrench our management and Board; or (iii) delay or prevent a merger, consolidation, takeover, or other business combination involving us on terms that other stockholders may desire.

Two of the stockholders, EW Healthcare and Ocumension have agreed that, for so long as such investor owns a number of shares equal to at least 75% of the shares of common stock it owns as of December 31, 2020, at any meeting of our stockholders, however called,

Substantial future sales or at any adjournment thereof, or in any other circumstances in which EW Healthcare or Ocumension, as applicable, are entitled to vote, consent or give any other approval, except as otherwise agreed to in writing in advance by us, EW Healthcare and Ocumension shall (a) appear at each such meeting or otherwise cause the sharesissuances of our common stock owned by such investor or their respective affiliates to be counted as present thereatcould depress the market for purposes of calculating a quorum; and (b) vote (or cause to be voted), in person or by proxy, all such shares of our common stock that are beneficially owned by such investor or as to which such investor has, directly or indirectly, the right to vote or direct the voting, (i) in favor of any proposals recommended by our board of directors for approval; and (ii) against any proposals that our board of directors recommends our stockholders vote against; provided, however, thatstock.

63

the foregoing does not apply to meetings or proposals that are inconsistent with the investor’s rights and obligations under certain agreements between the applicable investor and us.

In addition, eachSales of EW Healthcare and Ocumension currently have the right to nominate one or more individuals to our board of directors. While the directors appointed by EW Healthcare and Ocumension are obligated to act in accordance with their fiduciary duties under Delaware law, they may have equity or other interests in EW Healthcare or Ocumension and, accordingly, their personal interests may be aligned with EW Healthcare’s or Ocumension’s interests, which may not always coincide with our corporate interests or the interests of our other stockholders. The directors are required to disclose any potential material conflicts of interest. EW Healthcare nominated Dr. Göran Ando as a director in 2018. The current Ocumension nominated director is Ye Liu.

Certain covenants related to our share purchase agreement with Ocumension may restrict our ability to obtain future financing and cause additional dilution for our stockholders.

On December 31, 2020 we entered into a Share Purchase Agreement (the Share Purchase Agreement) with Ocumension Therapeutics, incorporated in the Cayman Islands with limited liability (Ocumension), pursuant to which we offered and sold to the Ocumension 3,010,722 shares of our common stock at a purchase price of $5.2163 per share, which was the five-day volume weighted average price of our common stock as of the close of trading on December 29, 2020 (the Ocumension Transaction). Pursuant to the Share Purchase Agreement, for so long as Ocumension owns asubstantial number of shares of our common stock, equal to at least 75% ofor the sharesperception by the market that those sales could occur, could cause the market price of our common stock to decline or could make it acquired atmore difficult for us to raise funds through the closingsale of equity in the Ocumension Transaction, Ocumension is entitled to participate in subsequent issuancesfuture.

In addition, certain of our equity securities in order to maintain its ownership percentage, subject to certain exceptionsemployees, executive officers, and directors have entered or may enter into Rule 10b5-1 trading plans providing for among other things, the issuance of equity awards pursuant to equity incentive plans, inducement awards and/or employee stock purchase plans and the issuancesales of shares of our common stock from time to time. Under a Rule 10b5-1 trading plan, a broker executes trades pursuant to “at-the-market”parameters established by the employee, director, or officer when entering into the plan, without further direction from the employee, officer, or director. A Rule 10b5-1 trading plan may be amended or terminated in some circumstances. Our employees, executive officers, and directors also may buy or sell additional shares outside of a Rule 10b5-1 trading plan when they are not in possession of material, nonpublic information, subject to the expiration of lock-up agreements, if applicable.

We expect to Ocumensioncontinue to incur commercialization, drug development and selling, general and administrative costs, and to satisfy our funding requirements, we may need to sell additional equity securities. The sale or the proposed sale of substantial amounts of our common stock or our other equity securities may adversely affect the market price of our common stock and our stock price may decline substantially. Our stockholders may experience substantial dilution and a reduction in the Share Purchase Agreement would be effected via a separate private placement. These participationprice that they are able to obtain upon sale of their shares. New equity securities issued may have greater rights, could severely impact our ability to engage investment bankers to structure a financing transaction and raise additional financing on favorable terms. Furthermore, negotiating and obtaining a waiver to these participation rights may either not be possiblepreferences, or may be costly to us. If Ocumension exercises its participation rights,privileges than our existing stockholders wouldcommon stock.

We do not currently intend to pay dividends on our common stock, and any return to investors is expected to come, if at all, only from potential increases in the price of our common stock.

We have never declared or paid cash dividends on our capital stock, and you should not rely on an investment in our common stock to provide dividend income. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. As a result, capital appreciation, if any, of our common stock will be further diluted toyour sole source of gain for the extent of the number of shares Ocumension acquires to maintain its ownership percentage.foreseeable future.

Provisions in our charter documents could prevent or delay stockholders’ attempts to takeover our company.

Our board of directors is authorized to issue “blank check” preferred stock, with designations, rights and preferences as they may determine. Accordingly, our board of directors may in the future, without stockholder approval, issue shares of preferred stock with dividend, liquidation, conversion, voting or other rights that could adversely affect the voting power or other rights of the holders of our common stock. This type of preferred stock could also be issued to discourage, delay, or prevent a change in our control. The ability to issue “blank check” preferred stock is a traditional anti-takeover measure. This provision in our charter documents makes it difficult for a majority stockholder to gain control of our company. Provisions like this may be beneficial to our management and our board of directors in a hostile tender offer and may have an adverse impact on stockholders who may want to participate in such a tender offer.

Provisions in our bylaws provide for indemnification of officers and directors, which could require us to direct funds away from our business and the development of our product candidates.

Our bylaws provide for the indemnification of our officers and directors. We may in the future be required to advance costs incurred by an officer or director and to pay judgments, fines and expenses incurred by an officer or director, including reasonable attorneys’ fees, as a result of actions or proceedings in which our officers and directors are involved by reason of being or having been an officer or director of our company. Funds paid in satisfaction of judgments, fines, and expenses may be funds we need for the operation of our business and the development of our product candidates, thereby affecting our ability to attain profitability.

GENERAL RISK FACTORS

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

Implementation of our developmentDevelopment and commercialization of our product candidate strategies will require additional managerial, operational, sales, marketing, financial, and other resources. Our current management, personnel, and systems may not be adequate to effectively manage the expansion of our operations, which may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business opportunities, employee turnover, and reduced productivity. Future growth could require significant capital expenditures and may divert financial resources from other projects, such as the development of our existing or future product candidates. Future growth would impose significant added responsibilities on members of management, including:

64

As our operations expand, we will need to manage additional relationships with various strategic collaborators, suppliers, and other third parties. Our future financial performance and our ability to commercialize our product candidates and to compete effectively will depend, in part, on our ability to manage any future growth effectively. To that end, we must be able to manage our development efforts and clinical trials effectively and hire, train and integrate additional management, administrative, and sales and marketing personnel. Failure to accomplish any of these activities could prevent us from successfully growing our company.

Our business and operations would suffer in the event of computer system failures, cyberattacks or a deficiency in our cybersecurity.

Despite the implementation of security measures, our internal computer systems and those of our contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures, cyberattacks or cyber-intrusions over the Internet, attachments to emails, persons inside our organization, or persons with access to systems inside our organization. The risk of a security breach or disruption, particularly through cyber-attacks or cyber intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. Such an event could cause interruption of our operations. As part of our business, we and our vendors maintain large amounts of confidential information, including non-public personal information on patients and our employees. Breaches in security could result in the loss or misuse of this information, which could, in turn, result in potential regulatory actions or litigation, including material claims for damages, interruption to our operations, damage to our reputation or otherwise have a material adverse effect on our business, financial condition and operating results. We expect to have appropriate information security policies and systems in place in order to prevent unauthorized use or disclosure of confidential information, including non-public personal information, but there can be no assurance that such use or disclosure will not occur.

If we fail to comply with data protection laws and regulations, we could be subject to government enforcement actions, which could include civil or criminal penalties, as well as private litigation and/or adverse publicity, any of which could negatively affect our operating results and business.

We may be subject to laws and regulations that address privacy and data security in the U.S. and in states in which we conduct our business. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues which may affect our business. In the U.S., numerous federal and state laws and regulations govern the collection, use, disclosure, and protection of health-related and other personal information, including state data breach notification laws, state health information privacy laws, state genetic privacy laws, and federal and state consumer protection and privacy laws (including, for example, Section 5 of the FTC Act and the CCPA). Compliance with these laws is difficult, constantly evolving, and time consuming. In addition, state laws govern the privacy and security of health, research and genetic information in specified circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Failure to comply with these laws and regulations could result in government enforcement actions and create liability for us, which could include civil and/or criminal penalties, as well as private litigation and/or adverse publicity that could negatively affect our operating results and business.

For instance, HIPAA imposes certain obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information and imposes notification obligations in the event of a breach of the privacy or security of individually identifiable health information on entities subject to HIPAA and their business

associates that perform certain activities that involve the use or disclosure of protected health information on their behalf. We may obtain health information from third parties (e.g., research institutions from which we obtain clinical trial data) that are subject to privacy and security requirements under HIPAA. Although we are not directly subject to HIPAA – other than potentially with respect to providing certain employee benefits – we could potentially be subject to criminal penalties if we, our affiliates, or our agents knowingly obtain, use, or disclose individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA.

In addition, the CCPA establishes certain requirements for data use and sharing transparency and provides California consumers (as defined in the law) certain rights concerning the use, disclosure, and retention of their personal data. In November 2020, California voters approved the California Privacy Rights Act (CPRA) ballot initiative which introduced significant amendments

65

to the CCPA and established and funded a dedicated California privacy regulator, the California Privacy Protection Agency (CPPA). The amendments introduced by the CPRA went into effect on January 1, 2023, and new implementing regulations are expected to be introduced by the CPPA. Failure to comply with the CCPA may result in, among other things, significant civil penalties and injunctive relief, or statutory or actual damages. In addition, California residents have the right to bring a private right of action in connection with certain types of incidents. These claims may result in significant liability and damages. Similarly, there are a number of legislative proposals in the United States, at both the federal and state level, that could impose new obligations or limitations in areas affecting our business. For example, other states, including Virginia, Colorado, Utah, Indiana, Iowa, Tennessee, Montana, Texas, and Connecticut have enacted privacy laws similar to the CCPA that impose new obligations or limitations in areas affecting our business. These laws and regulations are evolving and subject to interpretation and may impose limitations on our activities or otherwise adversely affect our business. The obligations to comply with the CCPA and evolving legislation may require us, among other things, to update our notices and develop new processes internally and with our partners. We may be subject to fines, penalties, or private actions in the event of non-compliance with such laws. In addition, we could be subject to regulatory actions and/or claims made by individuals and groups in private litigation involving privacy issues related to data collection and use practices and other data privacy laws and regulations, including claims for misuse or inappropriate disclosure of data, as well as unfair or deceptive acts or practices in violation of Section 5(a) of the Federal Trade Commission Act (FTC Act). The FTC expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered sensitive data that merits stronger safeguards. With respect to privacy, the FTC also sets expectations that companies honor the privacy promises made to individuals about how the company handles consumers’ personal information; any failure to honor promises, such as the statements made in a privacy policy or on a website, may also constitute unfair or deceptive acts or practices in violation of the FTC Act. Enforcement by the FTC under the FTC Act can result in civil penalties or decades-long enforcement actions.

If we, our agents, or our third party partners fail to comply or are alleged to have failed to comply with these or other applicable data protection and privacy laws and regulations, or if we were to experience a data breach involving personal information, we could be subject to government enforcement actions or private lawsuits. Any associated claims, inquiries, or investigations or other government actions could lead to unfavorable outcomes that have a material impact on our business including through significant penalties or fines, monetary judgments or settlements including criminal and civil liability for us and our officers and directors, increased compliance costs, delays or impediments in the development of new products, negative publicity, increased operating costs, diversion of management time and attention, or other remedies that harm our business, including orders that we modify or cease existing business practices.

Outside the U.S., the legislative and regulatory landscape for privacy and data security continues to evolve. There has been increased attention to privacy and data security issues that could potentially affect our business, including the EU General Data Protection Regulation including as implemented in the UK, (collectively, GDPR), which imposes penalties for the most serious breaches of up to EUR 20 million or 4% of a noncompliant company’s annual global revenue, whichever is greater. The GDPR regulates the processing of personal data (including health data from clinical trials) and places certain obligations on the processing of personal data including ensuring the lawfulness of processing personal data (including obtaining valid consent of the individuals to whom the personal data relates, where applicable), the processing details disclosed to the individuals, the adequacy, relevance and necessity of the personal data collected, the retention of personal data, the sharing of personal data with third parties, the transfer of personal data out of the European Economic Area/UK to third countries including the U.S., contracting requirements (such as with clinical trial sites and vendors), the use of personal data in accordance with individual rights, the security of personal data and security breach/incident notifications. Data protection authorities from the different European Member States and the UK may interpret the GDPR and applicable related national laws differently and impose requirements additional to those provided in the GDPR and that sit alongside the GDPR, as set out under applicable local data protection law. In addition, guidance on implementation and compliance practices may be issued, updated or otherwise revised. Enforcement by European and UK regulators is generally active, and failure to comply with the GDPR or applicable Member State/UK local law may result in fines, amongst other things (such as notices requiring compliance within a certain timeframe). Further, the UK Government may amend/update UK data protection law, which may result in changes to our business operations and potentially incur commercial cost.

European/UK data protection laws, including the GDPR, generally restrict the transfer of personal data from the European Economic Area (EEA), including the EU, United Kingdom, and Switzerland, to the U.S. and most other countries (except those deemed to be adequate by the European Commission/UK Secretary of State as applicable) unless the parties to the transfer have implemented specific safeguards to protect the transferred personal data. While previously U.S. companies could rely on self-certification to the EU-U.S.Some available lawful transfer mechanisms are under scrutiny and Swiss-U.S. Privacy Shield frameworks administered by the U.S. Department of Commercein flux, such as one of these safeguards to legitimize transfers from the EU and Switzerland to the U.S., this has been invalidated by the Court of Justice of the European Union (CJEU). The CJEU found that theCommission’s Standard Contractual Clauses (SCCs), one of the primary safeguards for legitimizing data transfers, were valid in principle, but placed obligations on the parties entering into them including to verify whether an adequate level of protection is provided in the recipient jurisdiction, and whether additional measures are required to bring the level

66

of protection in line with EU standards. Following this decision, the European Data Protection Board issued guidance on how organizations should approach international data transfers of GDPR-covered personal data, including the supplemental measures companies can adopt to help protect against overarching surveillance outside of the EU. In June 2021,. On July 10, 2023, the European Commission adopted a new set of SCCs aimed at enabling lawful transfers ofits adequacy decision for the EU-U.S. Data Privacy Framework, meaning that personal data to non-adequate countries outsidecan now flow freely from the EEA to U.S. companies that participate in the deadline for the adoption of which was December 27 2022.Data Privacy Framework. There are also recent developments regarding data transfers in the UK, which formally approved two mechanisms for transferring UK data overseas and that came into force on March 21, 2022: the International Data Transfer Agreement or the International Data Transfer Addendum to the SCCs. The UK Information Commissioner’s Office also issued guidance on how to approach undertaking risk assessments for transfers of UK data to non-adequate countries outside the UK.

A lack of valid transfer mechanisms for GDPR-covered data could increase exposure to enforcement actions as described above, and may affect our business operations and require commercial cost (including potentially limiting our ability to collaborate/work with certain third parties and/or requiring an increase in our data processing capabilities in the EU/UK). Further, the European/UK data protection laws (including laws on data transfers as set out above) may also be updated/revised, accompanied by new guidance and/or judicial/regulatory interpretations, which could entail further impacts on our compliance efforts and increased cost.

Additionally, other countries outside of Europe/UK have enacted or are considering enacting similar cross-border data transfer restrictions and laws requiring local data residency, which could increase the cost and complexity of delivering our services and operating our business. The type of challenges we face in Europe/UK will likely also arise in other jurisdictions that adopt laws similar in construction to the GDPR or regulatory frameworks of equivalent complexity.

In March 2022, the European Commission and the U.S. announced that they have agreed in principle on a new Trans-Atlantic Data Privacy Framework, as a successor arrangement to the EU-U.S. Privacy Shield. On December 13, 2022, the European Commission adopted a draft adequacy decision for the EU-U.S. Data Privacy Framework. This draft decision follows the signature of a U.S. Executive Order by President Biden on October 7, 2022, along with the regulations issued by the U.S. Attorney General Merrick Garland. These two instruments implemented into U.S. law the agreement in principle announced by President von der Leyen and President Biden in March 2022. The draft adequacy decision, which reflects the assessment by the European Commission of the U.S. legal framework has now been published and transmitted to the EDPB for its opinion. The draft decision concludes that the U.S. ensures an adequate level of protection for personal data transferred from the EU to U.S. companies. The two sides are now expected to finalize the details of this agreement in principle and translate it into legal texts that will form the basis of a draft adequacy decision to be proposed by the European Commission.

Furthermore, following the UK’s exit from the EU, the UK became a third country to the EU in terms of personal data transfers. The European Commission has adopted an Adequacy Decision concerning the level of personal data protection in the UK under which personal data may now flow freely from the EU to the UK. However, personal data transfers from the EU to the UK may nevertheless be at a greater risk than before because the Adequacy Decision may be suspended.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

We are increasingly dependent on sophisticated software applications and computing infrastructure to conduct key operations. We depend on both our own systems, networks, and technology as well as the systems, networks and technology of our contractors, consultants, vendors, and other business partners.

Cybersecurity Program

Given the importance of cybersecurity to our business, we maintain a robust cybersecurity program to support both the effectiveness of our systems and our preparedness for information security risks. This program includes a number of administrative, physical, and technical safeguards with regular evaluations of our cybersecurity program, including periodic internal and external audits, penetration tests, and incident response simulations. We also require cybersecurity training when onboarding new employees and contractors, as well as required cybersecurity awareness training for our employees and contractors/other workforce members. Our program leverages industry frameworks, including the National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF) to strengthen our program effectiveness and reduce cybersecurity risks.

We use a risk-based approach with respect to our use and oversight of third-party service providers. We use a number of means to assess cyber risks related to our third-party service providers, including maintaining vendor questionnaires/conducting due diligence in connection with onboarding new vendors and engaging in periodic reviews thereafter as appropriate.

Process for Assessing, Identifying and Managing Material Risks from Cybersecurity Threats

In the event of a cybersecurity incident, we maintain a regularly tested incident response program. Pursuant to the program and its escalation protocols, designated personnel are responsible for assessing the severity of an incident and associated threat, and handling it in accordance with that severity level. We have relationships with a number of third-party service providers to assist with cybersecurity containment and remediation efforts.

Governance

Upon a notification of concerning factors which may be indicative that a notable cybersecurity incident has occurred, the Cyber Security Subcommittee (Cyber Security Subcommittee) consisting of the Chief Legal Officer, Chief People Officer & SVP of IT, Associate General Counsel, Head of Information Technology, and a member of the Financial Reporting team, meets to make an initial assessment. If the Cyber Security Subcommittee determines there is a reasonable likelihood a notable cybersecurity incident has occurred, then notice will promptly be given to certain members of the Company Executive Team including our President/Chief Executive Officer, Chief Financial Officer, Chief Legal Officer & Corporate Secretary, and Chief People Officer/SVP of IT.

Our team leverages over 25 years of experience in various cyber security functions. Our SVP of IT, and her team, is responsible for the day-to-day management of the cybersecurity program.

The SVP of IT provides periodic briefings for our senior management team on cybersecurity matters, including the prevention, detection, mitigation, and remediation of cybersecurity incidents and cybersecurity threats.

Board Oversight

While the Board of Directors has overall responsibility for risk oversight, our Audit Committee oversees cybersecurity risk matters. The Audit Committee is responsible for reviewing, discussing with management, and overseeing the Company’s cybersecurity and privacy risk exposures and policies. On a quarterly basis, the SVP of IT reports to the Audit Committee on information technology and cybersecurity matters, including key information technology risks. The SVP of IT also apprises the Audit Committee and full Board of Cyber Security Incidents consistent with our incident response program, promptly.

Cybersecurity Risks

Our cybersecurity risk management processes are integrated into our overall Enterprise Risk Management (“ERM”) process. As part of our ERM process, department leaders identify, assess, and evaluate risks impacting our operations across the Company, including those risks related to cybersecurity. Department leaders are asked to consider the severity and likelihood of certain risk factors, drawing upon their company knowledge and past business experience. While we maintain a robust cybersecurity program, the techniques used to infiltrate information technology systems continue to evolve. Accordingly, we may not be able to timely detect threats or anticipate and implement adequate security measures. For additional information, see “Item 1A—Risk Factors.” To date, we have not experienced any material cybersecurity incidents or threats.

ITEM 2. PROPERTIES

We do not own any real property. We are headquartered in Watertown, Massachusetts, where we rent office, laboratory and manufacturing operations space. We entered into the original lease agreement on November 1, 2013, which included approximately 13,650 square feet of combined office and laboratory space for a term of five years, and was set to expire in April 2019. On May 17, 2018, we entered into an amendment to rent an additional 6,590 square feet of space and extend the term of the lease through May 31, 2025. We took occupancy of the additional space on September 10, 2018. On April 5, 2021, we further amended the lease by renting an additional 1,409 square feet of space and extending the term of the lease through May 31, 2025. We took occupancy of the additional space on July 1, 2021.

On March 8, 2022, we entered into an amendment (i) to extend the term of the lease to May 31, 2028 for 13,650 square feet of laboratory and manufacturing operations space; (ii) to rent an additional 11,999 square feet of office space through May 31, 2028, which commenced during the third quarter of 2022; and (iii) to terminate a portion of the lease comprising 7,999 square feet of office space in accordance with its existing contractual term on May 31, 2025. The amendment also reinstated our right to extend the lease for the space we occupy after May 31, 2025, for one additional period of five years. Rent for the extension period would be at the fair market rent for comparable space in comparable properties in the Watertown area.

67

On January 23, 2023, we entered into a lease agreement with V.E. Properties IX, LLC for a new standalone manufacturing facility, including office and lab space located at 600 Commerce Drive, Northbridge, Massachusetts. The new leased premises will consist of approximately 40,000 square feet. The lease includes a lease term of fifteen years and four months, with two options to extend the lease term for either five years or ten years at 95% of the then-prevailing fair market rent. The lease term will commence upon the substantial completion of construction to prepare the premises for our intended use, which is currently expected to occur duringin the second half of 2024.2024 (the “Lease Commencement Date”). Our obligation to pay base rent will begin four months following the Lease Commencement Date. We have the option to extend the lease for one additional 5-year term.

We believe our leased facilities are adequate for our present and anticipated needs. Please refer to Note 98 to the Consolidated Financial Statements, included under Item 15, "Exhibits and Financial Statement Schedules," for further details.

ITEM 3. LEGAL PROCEEDINGS

We are subject to various routine legal proceedings and claims incidental to our business, which management believes will not have a material effect on our financial position, results of operations or cash flows.

Summary of Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, (U.S. GAAP). The preparation of these financial statements requires that we make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience, anticipated results and trends and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily available from other sources. By their nature, these estimates, judgments and assumptions are subject

to an inherent degree of uncertainty, and management evaluates them on an ongoing basis for changes in facts and circumstances. Changes in estimates are recorded in the period in which they become known. Actual results may differ from our estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note 2 in the accompanying Notes to the Consolidated Financial Statements contained in this Annual Report on Form 10-K, we believe that the following accounting policies are critical to understanding the judgments and estimates used in the preparation of our financial statements. It is important that the discussion of our operating results that follows be read in conjunction with the critical accounting policies discussed below.

Revenue Recognition

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, Revenue from Contracts with Customers (ASC 606), we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. We only apply the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract, determines those that are performance obligations and assesses whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.

Product sales, net — We sellsold YUTIQ® and DEXYCU® to a limited number of specialty distributors and specialty pharmacies (collectively the Distributors) in the U.S., with whom we havehad entered into formal agreements, for delivery to physician practices for YUTIQ® and to hospital outpatient departments and ambulatory surgical centers (ASCs) for DEXYCU.DEXYCU®. We recognizerecognized revenue on sales of our products when Distributors obtainobtained control of the products, which occursoccurred at a point in time, typically upon delivery.

Components of variable consideration includeincluded trade discounts and allowances, provider chargebacks and discounts, payor rebates, product returns, and other allowances that arewere offered within contracts between us and our Distributors, payors, and other contracted purchasers relating to our product sales. These reserves as detailed below, arewere based on the amounts earned, or to be claimed on the related sales, and arewere classified either as reductions of product revenue and accounts receivable or a current liability, depending on how the amount iswas to be settled. Overall, these reserves reflectreflected our best estimates of the amount of consideration to which it iswas entitled based on the terms of the respective underlying contracts. ActualThe actual amounts of consideration ultimately received may differ from our estimates. If actual results in the future vary from the estimates, we adjust these estimates, which would affect product revenue and earnings in the period such variances become known.

Distribution fees — We compensate our Distributors for services explicitly stated in our contracts and they are recorded as a reduction of revenue in the period the related product sale is recognized.

Provider chargebacks and discounts — Chargebacks are discounts that represent the estimated obligations resulting from contractual commitments to sell products at prices lower than the list prices charged to our Distributors. These Distributors charge us for the difference between what they pay for the product and our contracted selling price. These reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability. Reserves for chargebacks consist of amounts that we expect to pay for units that remain in the distribution channel inventories at each reporting period-end that we expect will be sold under a contracted selling price, and chargebacks that Distributors have claimed, but for which we have not yet settled.

Government rebates — We are subject to discount obligations under state Medicaid programs and Medicare. These reserves are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability which is included in accrued expenses and other current liabilities on the consolidated balance sheets. Our liability for these rebates consists of invoices received for claims from prior quarters that have not been paid or for which an invoice has not yet been received, estimates of claims for the current quarter, and estimated future claims that will be made for product that has been recognized as revenue, but which remains in the distribution channel inventories at the end of each reporting period.

Payor rebates — We contract with certain private payor organizations, primarily insurance companies, for the payment of rebates with respect to utilization of our products. We estimate these rebates and records such estimates in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current liability.

Co-Payment assistance — We offer co-payment assistance to commercially insured patients meeting certain eligibility requirements. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per claim that we expect to receive associated with product that has been recognized as revenue.

Product returns — We generally offer a limited right of return based on our returned goods policy, which includes damaged product and remaining shelf life. We estimate the amount of our product sales that may be returned and record this estimate as a reduction of revenue in the period the related product revenue is recognized, as well as reductions to trade receivables, net on the consolidated balance sheets.

License and collaboration agreement revenue — We analyze each element of our license and collaboration arrangements to determine the appropriate revenue recognition. The terms of the license agreement may include payment to us of non-refundable upfront license fees, milestone payments if specified objectives are achieved, and/or royalties on product sales. We recognize revenue from upfront payments at a point in time, typically upon fulfilling the delivery of the associated intellectual property to the customer. For licenses that are combined with other promises, we determine whether the combined performance obligation is satisfied over time or at a point in time, when (or as) the associated performance obligation in the contract is satisfied.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. We determine standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, we estimate the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

We recognize sales-based milestone payments as revenue upon the achievement of the cumulative sales amount specified in the contract in accordance with ASC 606-10-55-65. For those milestone payments which are contingent on the occurrence of particular future events, we determine that these need to be considered for inclusion in the calculation of total consideration from the contract as a component of variable consideration using the most-likely amount method. As such, we assess each milestone to determine the

probability and substance behind achieving each milestone. Given the inherent uncertainty associated with these future events, we will not recognize revenue from such milestones until there is a high probability of occurrence, which typically occurs near or upon achievement of the event.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. Applying the practical expedient in paragraph 606-10-32-18, we do not assess whether a significant financing component exists if the period between when we perform our obligations under the contract and when the customer pays is one year or less. None of our contracts contained a significant financing component as of December 31, 2022.2023.

Reimbursement of costs — We may provide research and development services and incur maintenance costs of licensed patents under collaboration arrangements to assist in advancing the development of licensed products. We act primarily as a principal in these transactions and, accordingly, reimbursement amounts received are classified as a component of revenue to be recognized consistent with the revenue recognition policy summarized above. We record the expenses incurred and reimbursed on a gross basis.

Royalties — We recognize revenue from license arrangements with our commercial partners’ net sales of products. Such revenues are included as royalty income. In accordance with ASC 606-10-55-65, royalties are recognized when the subsequent sale of the commercial partner’s products occurs. Our commercial partners are obligated to report their net product sales and the resulting royalty due to us typically within 60 days from the end of each quarter. Based on historical product sales, royalty receipts and other relevant information, we recognize royalty income each quarter and subsequently determine a true-up when we receive royalty reports and payment from our commercial partners. Historically, these true-up adjustments have been immaterial.

Sale of Future Royalties — We have sold our rights to receive certain royalties on product sales. In the circumstance where we have sold our rights to future royalties under a royalty purchase agreement and also maintains limited continuing involvement in the arrangement (but not significant continuing involvement in the generation of the cash flows that are due to the purchaser), we defer recognition of the proceeds we receive for the sale of royalty streams and recognizes such unearned revenue as revenue under the units-of-revenue method over the life of the underlying license agreement. Under the units-of-revenue method, amortization for a reporting period is calculated by computing a ratio of the proceeds received from the purchaser to the total payments expected to be made to the purchaser over the term of the agreement, and then applying that ratio to the period’s cash payment.

Estimating the total payments expected to be received by the purchaser over the term of such arrangements requires management to use subjective estimates and assumptions. Changes to our estimate of the payments expected to be made to the purchaser over the term of such arrangements could have a material effect on the amount of revenues recognized in any particular period.

Research Collaborations — We recognize revenue over the term of the statements of work under any funded research collaborations. Revenue recognition for consideration, if any, related to a license option right is assessed based on the terms of any such future license agreement or is otherwise recognized at the completion of the research collaborations. Please refer to Note 3 for further details on the license and collaboration agreements into which we have entered and corresponding amounts of revenue recognized during the current and prior year periods.

Deferred Revenue

Amounts received prior to satisfying the above revenue recognition criteria are recorded as deferred revenue on the accompanying consolidated balance sheets. Amounts not expected to be recognized within one year following the balance sheet date are classified as non-current deferred revenue.

Please refer to Note 3 for further details on the license and collaboration agreements into which we have entered and corresponding amounts of revenue recognized for the years ended December 31, 20222023 and 2021.2022.

Recognition of Expense in Outsourced Clinical Trial Agreements

We recognize research and development expense with respect to outsourced agreements for clinical trials with contract research organizations (CROs) as the services are provided, based on information provided by CROs and our assessment of the services performed. We make our assessments of the services performed based on various factors, including evaluation by thereporting from third-party CROs and our own internal reviewtracking of the work performed during the period, measurements of progress by us or by the third-party CROs, data analysis with respectwhich are subject to work completed and our management’s judgment. Our financial obligations under the agreements are determined by the services that we request from time to time under the agreements. The actual amounts owed under the agreements and the timing of those obligations will depend on various factors, including changes to the protocols and/or services requested, the number of patients to be enrolled and the rate of patient enrollment, achievement of pre-defined direct cost milestone events, and other factors relating to the clinical trials.

We can terminate the agreements at any time without penalty, and if terminated, we would be liable only for services through the termination date plus non-cancellable CRO obligations to third parties.
