PART I

Item 1. Business.

Business Overview

Savara Inc. (together with its subsidiaries “Savara,” the “Company,” “we,” “our” or “us”) is a clinical stage biopharmaceutical company focused on rare respiratory diseases. Our leadsole program, molgramostim nebulizer solution (“molgramostim,” formerly referred to as Molgradex)(“molgramostim"), is an inhaled biologic, specifically an inhaled granulocyte-macrophage colony-stimulating factor (GM-CSF)("GM-CSF") in Phase 3 development for autoimmune pulmonary alveolar proteinosis (“aPAP”). Molgramostim is delivered via an investigational eFlow®a proprietary eFlow® Nebulizer System (PARI Pharma GmbH). Our management team has significant experience in orphan drug development and pulmonary medicine, identifying unmet needs, and effectively advancing product candidates to approval and commercialization.

Corporate Strategy

Our goal is to become a leader in rare respiratory therapeutics through the development and commercialization of novel, best-in-class medicines that address unmet medical needs in this field. Key elements of our strategy include:

Molgramostim – aPAP

Our leadsole product candidate is an inhaled biologic. Molgramostim is an inhaled formulation of recombinant human GM-CSF and is being developed for the treatment of aPAP. Pulmonary alveolar proteinosis (“PAP”) is a rare lung disease characterized by the accumulation of surfactant in the alveoli (or air sacs) of the lungs. There are different types of PAP, of which aPAP is the most common.

In May 2019, the U.S. Food and Drug Administration (“FDA”)FDA granted Fast Track Designation to molgramostim for the treatment of aPAP. Fast Track Designation facilitates the development and expedites the review of new drugs or biologics intended to treat serious or life-threatening conditions that demonstrate the potential to address unmet medical needs. In December 2019, althoughthough the data from the IMPALA dataPhase 2/3 trial, previously conducted by us and further described herein, did not meet the regulatory requirement for approval, the FDA granted a Breakthrough Therapy Designation (“BTD”) for molgramostim in aPAP based on data from the 24-week double-blind treatment period from our IMPALA trial. Additionally, molgramostim was granted Orphan Drug Designation for the treatment of aPAP in the U.S. and the European Union (“EU”), which allows for seven and ten years of exclusivity from approval, respectively. Savara has exclusive access to the investigational, proprietary PARI eFlow® Nebulizer System for this indication along with a proprietary cell bank for the active drug substance of molgramostim. Additionally, in the United Kingdom ("UK"), molgramostim a non-glycosylated inhaled formfor the treatment of GM-CSF.aPAP was granted Innovation Passport (June 2022) and Promising Innovative Medicine (August 2022) designations by the UK Medicines and Healthcare Products Regulatory Agency (MHRA). These designations provide the opportunity for

enhanced dialogue and input from the MHRA and the Health Technology Assessment bodies in England, Scotland, and Wales.

In 2019, we announced that IMPALA, the Phase 2/3 clinical trial of molgramostim for the treatment of aPAP did not meet its primary endpoint of improvement compared to placebo in the alveolar-arterial oxygen gradient, or (A-a)DO2, improvement compared to placebo. TheDO2, from baseline at week 24. While the trial did not meet its primary endpoint, the totality of data from the IMPALA trial gives us confidence that molgramostim has the potential to address a significant unmet need in this rare lung disease. These data include:

4

In September 2020, results from the IMPALA trial were published in the New England Journal of Medicine. We consider molgramostim to have a favorable risk-benefit profile and remain confident in the future of the program, including the current Phase 3 IMPALA-2 pivotal trial.

As of December 31, 2021,2023, our Phase 3 IMPALA-2 pivotal trial, which builds on key learnings from the IMPALA trial is underway.remains on track. During 2021,2022 and 2023, we activated manyand managed our clinical trial sites, enrolled patients and further, we announcedcompleted enrollment at the dosingend of our first patient occurred on June 30, 2021. Since that time, we have continued to enroll additional patients.the second quarter of 2023.

We also received acceptance from the Pediatric Committee of the European Medicines Agency (“EMA”)(EMA) and the UK MHRA for a proposed revised pediatric investigation planPediatric Investigational Plan (“PIP”) for molgramostim.

Molgramostim – NTM

Molgramostim was also being investigated in cystic fibrosis (“CF”) and non-CF patients for the treatment of nontuberculous mycobacterial (“NTM”) lung infection, a rare and serious lung disorder. The ENCORE trial stopped enrolling patients in March 2020 due to limitations caused by COVID-19, and the decision to discontinue the trial was announced in September 2020. Based on the results of the exploratory OPTIMA trial, and preliminary data from the exploratory ENCORE trial, we decided to focus molgramostim development efforts on our lead indication, aPAP, and not to conduct further development activities related to molgramostim in NTM.

Vancomycin hydrochloride inhalation powder

Vancomycin inhalation powder (“vancomycin,” formerly referred to as AeroVanc) was the first inhaled antibiotic in development for the treatment of persistent methicillin-resistant Staphylococcus aureus (“MRSA”) lung infection in individuals living with CF and was being investigated in a randomized, double-blind, placebo-controlled Phase 3 clinical trial called AVAIL.

In December 2020, we announced the AVAIL trial did not meet the primary endpoint of mean absolute change from baseline in FEV1 percent predicted analyzed sequentially at week 4, 12, and 20. According to statistical hierarchy, if the trial did not show a statistically significant improvement in FEV1, the sequence of analysis would end.

Based on the AVAIL results, we discontinued further development of the vancomycin program in December 2020.

Inhaled liposomal ciprofloxacin

In March 2020, we entered into an exclusive license and collaboration agreement with Grifols, S.A. (“Grifols”) for inhaled liposomal ciprofloxacin (“Apulmiq”). Apulmiq is a late-stage investigational inhaled antibiotic for the treatment of non-cystic fibrosis bronchiectasis (“NCFB”). Under the terms of the agreement, Savara obtained the worldwide rights to develop and commercialize Apulmiq. However, as part of our December 2020 pipeline simplification strategy that focused resources on molgramostim in aPAP and the IMPALA-2 trial, we discontinued the Apulmiq clinical development program.

Detailed Program Description

Molgramostim

Background on aPAP

Autoimmune PAP,pulmonary alveolar proteinosis, known as aPAP, is a specific disease belonging to a family of distinct rare lung diseases collectively referred to as PAP. Autoimmune PAP ("aPAP")aPAP represents about 90% of all patients with PAP and the estimated prevalence of PAP is six to seven cases per million people in the U.S., with similar or higher prevalence reported elsewhere in the world. For example, Japan, a country that undertakes a more centralized approach to diagnosing and treating PAP, has seen a consistent increase in patients being diagnosed with the disease. It is now estimated the prevalence in Japan could be three to four times the original estimate of six to seven cases per million.

PAPaPAP is characterized by the accumulation of surfactant in the alveoli, or air sacs, of the lungs. The surfactant consists of proteins and lipids and is an important physiological substance that lines the inside of the alveoli to prevent the lungs from collapsing. The lungs continuously produce new active surfactant. In a healthy lung, the surfactant is cleared by immune cells called alveolar macrophages. However, in lungs of patients with aPAP, the macrophages fail to clear the surfactant from the alveoli, leading to gradual accumulation of surfactant in the alveoli. The root cause of aPAP is an autoimmune response against GM-CSF, a naturally occurring protein in the body. Pulmonary macrophages need to be stimulated by GM-CSF to function properly, but in aPAP, GM-CSF is neutralized by antibodies against GM-CSF, rendering the macrophages unable to perform their tasks, including the clearance of surfactant from the alveoli.

5

aPAP most commonly affects menindividuals in early middle age, but both sexes and patientspeople of any age can be affected. As a result of the accumulation of surfactant, gas exchange in the lungs is obstructed, and patients start to experience shortness of breath, fatigue, and decreased exercise tolerance. Typically, shortness of breath is first observed upon exertion, but as the disease progresses, shortness of breath can be experienced even when a person is at rest. Patients may experience cough, sputum production, and episodes of fever, especially if secondary lung infection develops. In the long-term, the disease can lead to serious complications, including pulmonary fibrosis, and often potentially leading to the need for lung transplantation.

Current treatment options for aPAP

There is no approved medicine for the treatment of aPAP. The current standard-of-care for aPAP is a non-standardized procedure called Whole Lung Lavage (“WLL”), which entails washing out the lungs with saline, most commonly, one lung at a time, to physically remove excess surfactant from the lungs. The invasive and inconvenient procedure is performed under general anesthesia and involves:

Potential complications from WLL include rib fracture, hypoxia, pneumothorax (collapsed lung), hydrothorax (fluid in pleural cavity), superimposed infection, and Acute Respiratory Distress Syndrome (ARDS).Syndrome.
 

WLLs are performed by highly experienced physicians at specialist sites and necessitatesnecessitate hospitalization. In manymost patients, WLL may only provide temporary symptomatic relief. Once the lungs refill with surfactant, the WLL procedure needs to be repeated.

As there are no approved pharmaceutical treatments available for aPAP, there is an unmet need for a convenient and efficacious medicinal treatment. We believe that inhalation of molgramostim activates macrophages in the lung alveoli, thus potentially restoring the surfactant clearingsurfactant-clearing activity of the alveolar macrophages and considerably improving oxygenation and exercise tolerance. Sargramostim (Leukine®), an injectable form of GM-CSF, is approved in the U.S. for intravenous (“IV”) and subcutaneous administration (“SC”) treatment of neutropenia caused by cancer chemotherapy and other related indications. Currently, there are no approved inhalation formulations of GM-CSF. GM-CSF products administered systemically (e.g., by injection), including molgramostim, are unlikely to benefit patients with aPAP because aPAP patients have circulating antibodies against GM-CSF. These antibodies would likely neutralize systemically administered GM-CSF before reaching the alveolar space in the lung.

The potential benefits of inhaled GM-CSF in aPAP, together with the availability of sargramostim (Leukine®) for off-label compounding, have prompted independent clinicians and academic researchers in the U.S., Europe,Japan and Japancountries in Europe to study the safety and efficacy of inhaled GM-CSF in aPAP patients. In addition to our Phase 2/3 IMPALA trial of molgramostim, the largest completed placebo-controlled trial in this patient population (n=138), several investigator-sponsored, open-label clinical trials and case studies of inhaled GM-CSF treatment have been published, with promising results on the efficacy and safety of the treatment. In total, treatment of nearly 150 aPAP patients with inhaled GM-CSF has been reported in open-label trials or retrospective cohorts, as well as several individual case reports. In PAGE, a randomized, double-blind, placebo-controlled, 25-week clinical trial of inhaled sargramostim (Leukine®) in 64 patients with mild-to-moderate disease, a significant effect was observed in the primary endpoint, which was change from baseline in (A-a)DO2. Secondary endpoints, including changes from baseline in diffusing capacity for carbon monoxide (“DLCO”), six-minute walk distance (“6MWD”), and aPAP serum biomarkers, showed directional, but in most cases not statistically significant, treatment effects over placebo. Overall, for the first time, the PAGE trial showed in a placebo-controlled setting, proof-of-concept for GM-CSF inhalation therapy in aPAP. Results from these investigator-sponsored clinical trials and case studies indicate that GM-CSF may have a positive impact on oxygenation and clinical symptoms in aPAP patients. For details on the results of the IMPALA trial, please see the Clinical Development of Molgramostim―Molgramostim – aPAP: Phase 2/3 IMPALA Trial section included in this report.

According to our review of published literature, few safety issues related with GM-CSF inhalation in patients with aPAP have been reported. However, there is still limited information available on the long-term safety of inhaled GM-CSF.

Product Description

6

Molgramostim is a non-glycosylated form of recombinant human GM-CSF that we are developing as an inhaled formulation for the treatment of aPAP. GM-CSF is an endogenous growth factor that stimulates the proliferation and differentiation of hematopoietic cells (blood immune cells), mainly granulocytic and monocytic cell lines,cells, which defend against bacteria and viruses, and clear cellular debris and waste substances from the body. Molgramostim is produced in a strain of Escherichia coli bearing a genetically engineered plasmid containing a human GM-CSF gene.

Our product is a drug-device combination consisting of molgramostim nebulizer solution (drug component) and a vibrating mesh nebulizer (device component). Molgramostim nebulizer solution is vialedsupplied as a sterile formulation containing 300 µg of molgramostim in 1.2 mL solution. Molgramostim nebulizer solution is administered once daily by inhalation via a high efficiency nebulizer, the investigational, proprietary eFlow® Nebulizer System (PARI Pharma GmbH). The eFlow® Nebulizer System is a reusable electronic inhalation system that has been optimized for administration of molgramostim nebulizer solution.molgramostim. The eFlow® consists of a controller unit (AC or battery powered), a nebulizer handset, and a connection cord. The controller unit's lifespan is multiple years and the handset is replaced monthly with a new unit.

Molgramostim was granted Orphan Drug Designation by the FDA in October 2012 and by the EMA in July 2013 for the treatment of aPAP. It was also granted Fast Track Designation and Breakthrough Therapy DesignationBTD by the FDA in May 2019 and December 2019, respectively. Further, it was granted Innovation Passport (June 2022) and Promising Innovative Medicine (August 2022) designations in the UK. Since 2014, molgramostim has been available in several European countries for the treatment of aPAP for named patients following unsolicited physician requests.

We anticipate that, if approved, molgramostim will be used as a long-term treatment in patients with aPAP. TreatmentOnce daily treatment with molgramostim is expected to reduce or potentially eliminate the need for WLL in patients with aPAP. In the IMPALA trial, a reduced number of WLL procedures in the active treatment arms was seen compared to the placebo treatment arm, but the difference was not statistically significant, possibly because of low number of WLL procedures seen in the IMPALA trial.significant.

Molgramostim Key Advantages

Based on data from the completed Phase 2/3 IMPALA trial and building upon the published investigator-sponsored treatment experience with inhaled GM-CSF, we believe molgramostim has the potential to become the treatment of choice for aPAP. The following characteristics of molgramostim may contribute to the clinical profile of the investigational product candidate, as well as facilitate potential regulatory approval and successful commercialization.

Specifically, molgramostim offers:

Phase 3 IMPALA-2 Pivotal Trial

7

IMPALA-2 is a Phase 3, 48-week, randomized, double-blind, placebo-controlled pivotal clinical trial designed to compare the efficacy and safety of molgramostim 300 µg administered once daily by inhalation with matching placebo in adult patients with aPAP. The primary endpoint is the change from baseline in percent predicted DLCO, a gas exchange measure. Three secondary endpoints will evaluate clinical measures of direct patient benefit: St. George’s Respiratory Questionnaire (“SGRQ”) Total Score, SGRQ Activity Component Score, and exercise capacity test using a treadmill test.treadmill. Other efficacy endpoints will include (A-a)DO2 (another gas exchange measure), supplemental oxygen use, WLL frequency, patient and clinician global impression of disease severity and disease change, chest computed tomography (“CT”) scan to assess lung opacity, and blood biomarkers. Enrollment in IMPALA-2 iswas completed at the end of June 2023 with 164 patients, exceeding the expected to enroll a totaltrial enrollment of approximately160160 patients. The patients who will bewere randomized to receive treatment for

48 weeks in one of two arms: molgramostim 300 µg administered once daily or inhaled placebo administered once daily. The primary time point for efficacy assessment will beis at week 24, however, efficacy will be assessed through week 48 to show durability of effect. Safety will be assessed through week 48. Following the 48-week double-blind treatment period, patients will roll overtransition to a 48-week96-week open-label period and will receive molgramostim 300 µg administered once daily.

In January 2021, we engaged Parexel International Limited (“Parexel”), a global contract research organization (“CRO”) to support our IMPALA-2 clinical trial operational activities. The IMPALA-2 pivotal trial design has been endorsed by regulatory authorities in the USAU.S. (FDA), Europe (EMA), UK (MHRA), and Japan (PMDA), and also by regulatory bodies and ethics committees in individual countries in North America, Europe, Asia, and Australia where the trial is being conducted. WeOn June 30, 2021, we announced the first patient had been dosed ondosed. On June 30, 2021, and since then26, 2023, we have continued to activate sites and enroll patients.announced the trial had completed enrollment. The trial conduct inis on track and is projected to fully enroll in approximately 20 months following initiation. Toptop line data are anticipated inexpected at the second quarter of end of 2Q 2024. While we are working to complete the IMPALA-2 pivotal trial as quickly and as safely as possible, the impact of the COVID-19 pandemic and emerging variants,global health threats, as well as supply chain issues and geopolitical unrest in certain geographies, continues to evolve and may adversely impact trial timelines in the future.

Phase 2/3 IMPALA Trial

IMPALA was a Phase 2/3 randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of molgramostim in adult patients with aPAP. Conducted in 18 countries including the U.S., Japan, Israel and various European countries including Turkey, it was the largest controlled clinical trial of molgramostim for the treatment of aPAP. Patients were randomized to receive treatment for up to 24 weeks in one of three treatment arms: 1) molgramostim 300 µg administered once daily (“continuous dosing arm”), 2) molgramostim 300 µg and matching placebo administered daily every other week (“intermittent dosing arm”), or 3) inhaled placebo administered once daily. At the end of the 24-week double-blind period, all patients received molgramostim 300 ug administered daily in every other week intermittent cycles in a 24-week open-label follow up period. The primary endpoint of the trial was (A-a)DO2, a measure of oxygenation impairment.gas exchange measure. In addition, three key secondary endpoints―endpoints – SGRQ, 6MWD, and time to/requirement for WLL―WLL – along with multiple other exploratory endpoints were assessed to determine improvement in the disease pathology, pathophysiology, clinical symptoms, and function.

The pathogenesis of aPAP is well known and GM-CSF’s effect on the disease, as evaluated by (A-a)DO2, dyspnea, 6MWD, pulmonary function tests, CT scores, and biomarkers, is well documented through published clinical trials. While IMPALA did not meet its primary endpoint, when looking at the totality of evidence, we believe that data from the IMPALA trial demonstratedemonstrated reversal of lung pathology and pathophysiology, improvement in clinical outcomes, and reduction of the need for rescue treatment, with a clear dose-frequency dependency in favor of the continuous dosing arm. Such results are detailed below:

8

In these four patients, (A-a)DO2 values distributed quite differently compared to the remaining trial population―population – ranging from highly negative to highly positive. In a revised analysis that excluded these four patients, a statistically significant average (A-a)DO2 improvement was observed in the continuous dosing arm compared with the placebo arm.

Impaired gas transfer and oxygenation are key pathophysiologic features of aPAP and are associated with symptoms of shortness of breath and limitations in exercise capacity. In addition to (A-a)DO2, DLCO was assessed as a secondaryan exploratory endpoint to evaluate the efficacy of molgramostim on gas transfer. Patients in the continuous dosing arm showed a mean improvement of 11.6% predicted in DLCO, whereas the intermittent dosing and placebo arms showed a 7.7% predicted and 3.9% predicted improvement, respectively. The estimated treatment difference of 7.9% predicted (p=0.007) between the continuous dosing arm and placebo was statistically significant, and in keeping with the (A-a)DO2 improvement, and suggests improved gas exchange in the lungs.

Results from the open-label period of the IMPALA trial, announced in March 2020, demonstrated a sustained treatment effect, or continued improvement, after longer term exposure to molgramostim. A summary of the results is provided below.

(A-a)DO2 improvement from baseline continued in these patients during the open-label period of the trial, with progressively larger improvements at weeks 48 and 72. Likewise, progressively larger improvements from baseline were observed in DLCO and SGRQ at weeks 48 and 72.

Placebo patients that transitioned to active drug showed similar average improvements in (A-a)DO2, DLCO, and SGRQ in the open-label period as compared to the continuous dosing group during the double-blind period, reaching similar levels of improvement to the continuous dosing group by week 72.

Similar trends were seen in the 6MWD at weeks 48 and 72, but the data were less conclusive.

Under the PARI License Agreement, we have a worldwide, exclusive license to commercialize PARI’s eFlow Nebulizer System for the pulmonary delivery of any liquid formulation containing recombinant human GM-CSF (“hGM-CSF”rhGM-CSF”) as the sole active pharmaceutical ingredient for nebulization for aPAP. Additionally, we have the option to change the device, subject to certain conditions, to PARI’s eFlow Technology Nebulizer Closed System (“CS”) and, until marketing approval, the option to negotiate an extension to the license to cover commercialization of the drug for pulmonary delivery via the PARI eFlow Inline device for the treatment of certain other indications. Following an amendment in 2018 (the “PARI Amendment”), we have the option to add other pulmonary infections to the included indications in the future.

Under the terms of the PARI License Agreement, Savara is not permitted to work with third parties to develop any inhalation device or nebulizer for the pulmonary delivery of a pharmaceutical product containing GM-CSF as the sole active ingredient. This restriction extends until (i) in the European Economic Area, until marketing approval of the product in Europe or the U.S., whichever is later, or (ii) in the rest of the world, until the termtermination of the PARI License Agreement.

In consideration of rights granted by PARI, our predecessor paid a one-time upfront fee, and we pay an hourly rate for work performed by PARI. Additionally, we are obligated to make future milestone payments to PARI based upon (i) the successful completion of certain clinical trials, (ii) submissions for regulatory approval in the U.S, the EU or Japan, and (iii) the first marketing approval for the product in the U.S., EU or Japan. The PARI Amendment expanded the development milestones in the agreement to include any additional pulmonary indications for which we use the device.

If we successfully commercialize any product candidate subject to the PARI License Agreement, in a country, we are responsible for royalty payments equal to a percentage of net sales. We are obligated to make such royalty payments until the later of (i) the expiration of the last valid claim in an issued patent covering a portion of the PARI device in the applicable country or (ii) 15 years after the first commercial sale of molgramostim with the PARI device in that country (the “PARI Royalty Period”). If there is no such valid patent claim covering the applicable PARI device, the royalty owed to PARI will be decreased by a specified percentage.

The license term extends on a country-by-country basis until the end of the PARI Royalty Period or until mutually agreed by the parties.

We also have a commercial supply agreement with PARI (the “PARI Supply Agreement”) related to the supply of the PARI eFlow® Nebulizer System and related accessories for commercial use with our products after marketing approval is obtained. Pursuant to the PARI Supply Agreement, we are obligated to purchase from PARI (i) within the European Economic Area, (a) during the first five years from marketing approval, all of our requirements for the device and related accessories and (b) thereafter 80% and (ii) in the rest of the world, all of our requirements during the PARI Royalty Period. Pricing is on a per unit basis, with a reduction in price once certain purchasing volumes are met.

GEMA Biotech S.A.

In April 2019, we entered into a Manufacture and Supply Agreement with GEMA, which was amended on December 7, 2022 and December 13, 2023 (the “GEMA Agreement”), pursuant to which GEMA will supply the active pharmaceutical ingredient (“API”) for molgramostim exclusively to us for commercial sale and continue to supply the API to us for clinical trials and research and development activities. Additionally, GEMA transferred and assigned to us all right, title,rights, titles, and interest in and to the master cell bank and working cell bank necessary to produce the API.

Pursuant to the terms of the GEMA Agreement, GEMA agreed to undertake the actions required to comply with the requirements of the FDA and other similar regulatory authorities and obtain the approvals necessary to manufacture and supply the API to us for commercial sale.

In addition to an agreed upon price per vial of 1 gram of the API, we paid GEMA a milestone payment upon the effective date of the agreement and are required to make milestone payments upon (i) completion of certain developmental activities, (ii) successful completion of an audit by the FDA,a mock pre-approval inspection, and (iii) marketing approval of a product containing the API. If we successfully commercialize a product containing the API in a country, we must pay GEMA a single digit percentage royalty on annual net sales. We are obligated to make such royalty payments until the earlier of (i) 10 years after the first receipt of marketing approval for the product in that country or (ii) the date a biosimilar of such product is first sold in that country.

11

Additionally, the Company is subject to a purchase obligation for ten years following the date of receipt of approval by a regulatory authority of the first regulatory filing for the marketing and sale of the first molgramostim product in any country. Each year, the Company will purchase from the GEMA the API required to produce a percentage of such molgramostim product it sells (the “Purchase Requirement”); provided, however, that the Purchase Requirement will no longer apply if (i) the price charged by the API manufacturer exceeds a certain price charged by an alternative supplier, (ii) there is a shortage of supply, or (iii) API manufacturer at any time fails to materially fulfill a purchase order of the Company.

The term of the GEMA Agreement continues until the twentieth anniversary of the date of receipt of marketing approval for a product containing the API in any country and may be extended for additional twelve-month terms by the agreement of both parties. We may terminate the GEMA Agreement immediately if (i) products containing the API will not be sold or will be withdrawn from the market, (ii) the FDA or other regulatory authority withdraws marketing approval for or fails to approve products incorporating the API, (iii) three or more batches of API supplied in any six month period fail to conform to specifications, (iv) GEMA receives notice of deficiencies in its manufacturing and fails to adequately respond, or (v) GEMA fails to achieve compliance with the requirements of the FDA and other regulatory authorities necessary to manufacture and supply the API to us for commercial sale.

Fujifilm Diosynth Biotechnologies

In February 2024, we entered into a master services agreement with Fujifilm pursuant to which Fujifilm will continue to provide development and manufacturing services related to active pharmaceutical ingredient for molgramostim in accordance with the terms of separate scope of work agreements to be entered into by the parties. In conjunction with execution of the master services agreement, the Company executed a scope of work between the parties, under which Fujifilm will perform a manufacturing campaign for Process Performance Qualification of the active pharmaceutical ingredient of molgramostim.

The master services agreement will continue until it is terminated by the Company or Fujifilm, which either party may do upon three months’ notice if no activities under a scope of work are in process. The Company may terminate activities under a scope of work at any time by providing written notice, subject to the payment of termination fees, as well as payment for services performed and non-cancelable costs. The master services agreement and any scope of work may also be terminated by either party due to a material uncured breach by the other party, and Fujifilm may terminate for certain unforeseen technical issues.

Patheon UK Limited

We have entered into an agreement and related work orders with Patheon under which Patheon manufactures our molgramostim product candidate for clinical trials. We may terminate the agreement at any time for any business reason.

In June 2019, we entered into a Master Manufacturing Services Agreement (the “Master Manufacturing Agreement”) with Patheon and expect in the future to enter into one or more related Product Agreements (each a “Product Agreement) pursuant to the Master Manufacturing Agreement to govern the terms and conditions of Patheon’s manufacture of commercial supplies of molgramostim.

The Master Manufacturing Agreement has an initial term ending December 31, 2024, and will automatically renew after the initial term for successive terms of two years each if there is a Product Agreement in effect, unless a party has given notice of termination. Either party may terminate the Master Manufacturing Agreement upon the other party’s uncured material breach or insolvency. Patheon may terminate the Master Manufacturing Agreement if we assign such agreement to an assignee that is unacceptable to Patheon for certain reasons, for failure of our timely payment of invoices, or if we forecast zero volume for six months.

Inhaled liposomal ciprofloxacin (Apulmiq)Diagnostic Testing

aPAP ClearPath™

In March 2020,December 2023, we entered into an exclusive licenselaunched aPAP ClearPath™, a new serum-based blood test that can be used by physicians in the U.S. to obtain a definitive diagnosis of aPAP. The aPAP ClearPath™ test is a sensitive and collaboration agreementspecific quantitative immunoassay designed to detect aPAP GM-CSF autoantibodies in human serum. We partnered with Grifols for Apulmiq forTrillium Health, a modern health solutions provider and a Clinical Laboratory Improvement Amendments (CLIA)-certified lab, to develop the treatmentsimple, no-cost, and noninvasive test. A supporting disease awareness campaign was also launched to improve understanding of NCFB. UnderaPAP, highlight the termshallmark signs and symptoms of the agreement, Savara obtained an exclusive, worldwide, royalty-bearing license, with rightsdisease, and educate physicians about the need for early testing. We expect to sublicense, patent rightsroll out a healthcare provider disease awareness campaign and know-how owned or controlled by Grifols to develop and commercialize Apulmiq. The term of the license continues until the Royalty Term (as definedGM-CSF autoantibody blood test in the license agreement) expires in all countries for all products containing Apulmiq. Grifols may terminate the license immediately if (1) we or one of our affiliates files a challenge to a patent owned by Grifols or (2) we fail to develop Apulmiq for 12 consecutive months. Either party can terminate for the other party’s material breach following a cure period or upon certain insolvency events.

As part of our December 2020 pipeline optimization strategy that focused our resources on molgramostim in aPAP and the IMPALA-2 trial, we discontinued the Apulmiq clinical development program.Europe during 2024.

Government Regulation

The FDA and other regulatory authorities at federal, state, and local levels, as well as in foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, post-approval monitoring, and post-approval reporting of drugs, such as those we are developing. We, along with third-party contractors, will be required to navigate the various preclinical, clinical and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our product candidate. The process of obtaining regulatory approvals and the subsequent compliance with appropriateapplicable federal, state, local, and foreignglobal statutes and regulations require the expenditure of substantial time and financial resources.

Government Regulation of Drugs

United StatesU.S.

The process required by the FDA before drug product candidates, like ours, may be marketed in the U.S. generally involves the following:

12

The testing and approval process requires substantial time, effort, and financial resources, and we cannot be certain that any approvals for our product candidate will be granted on a timely basis, if at all. Prior to beginning the first clinical trial with a product candidate, we must submit an Investigational New Drug Application (“IND”)IND to the FDA. An IND is a request for authorization from the FDA to administer an investigational new drug product to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for clinical trials. The IND also includes results of animal and in vitro trials assessing the toxicology, pharmacokinetics, pharmacology, and pharmacodynamic characteristics of the product candidate; chemistry, manufacturing, and controls information; and any available human data or literature to support the use of the investigational product. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA unless the FDA, within the 30-day time period, raises safety concerns or questions about the proposed clinical trial. In such a case, the IND may be placed on clinical hold and the IND sponsor, and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial.

Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in accordance with cGCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. Furthermore, an independent IRB, for each site proposing to conduct the clinical trial, must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site, and must monitor the trial until completed. Regulatory authorities, the IRB, or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some trials also include oversight by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board, which provides authorization for whether or not a trial may move forward at designated check points based on access to certain data from the trial and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to public registries.

For purposes of BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap. Additionally, in certain instances, a fourth phase, post approval, may be necessary or required.

13

Phase 1, Phase 2, and Phase 3 testing may not be completed successfully within a specified period, if at all, and there can be no assurance that the data collected will support FDA approval or licensure of the product. Concurrent with clinical trials, companies may complete additional animal studies and develop additional information about the drug characteristics of the product candidate and must finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deteriorationacceptably maintains its quality attributes over its shelf life.

BLA Submission and Review by the FDA

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, nonclinical studies, and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more indications. The BLA must include all relevant data available from pertinent preclinical and clinical studies, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls, and proposed labeling, among other things. Data can come from company-sponsored clinical trials intended to test the safety and effectiveness of a use of the product, or from a number of alternative sources, including trials initiated by investigators. The submission of a BLA requires payment of a substantial user fee to the FDA, and the sponsor of an approved BLA is also subject to annual product and establishment user fees. These fees are typically increased annually. A waiverAs noted previously, molgramostim nebulizer solution for the treatment of user fees may be obtainedaPAP has been granted Orphan Drug Designation, and as such is exempt from the payment of User Fees under certain limited circumstances.current legislation.

Within 60 days following submission of the application, the FDA reviews a BLA to determine if it is substantially complete before the agency accepts it for filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the BLA must be resubmitted with the additional information. Once a BLA has been filed, the FDA’s goal is to review the application within ten months after it accepts the application for filing, or, if the application relates to an unmet medical need in a serious or life-threatening indication, six months after the FDA accepts the application for filing. The review process is often significantly extended by FDA requests for additional information or clarification. The FDA reviews a BLA to determine, among other things, whether a product is safe and effective for the indication being pursued, and the facilityfacilities in which it is manufactured, processed, packed, or held meets standards designed to assure the product’s continued safety and effectiveness. The FDA may convene an advisory committee to provide clinicalindependent expert insight on application review questions. Before approving a BLA, the FDA will typically 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. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to assure compliance with cGCP. If the FDA determines that the application, manufacturing process, or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

The testing and approval process requires substantial time, effort, and financial resources, and each may take several years to complete. The FDA may not grant approval on a timely basis, or at all, and we may encounter difficulties or unanticipated costs in our efforts to secure necessary governmental approvals, which could delay or preclude us from marketing our products.product(s). After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or our drug substance will be produced, the FDA may issue an approvalApproval letter or a Complete Response Letter. An approvalApproval letter authorizes commercial marketing of the product in compliance with specific prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete, and the application is not ready for approval. A Complete Response Letter may request additional information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product.

If regulatory approval of a product is granted, such approval may entail limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the BLA with a Risk Evaluation and Mitigation Strategy (“REMS”) to mitigate risks, which could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries, and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing

14

regulatory standards is not maintained or if problems occur after the product reaches the marketplace. The FDA may

require one or more Phase 4 post-marketing trials and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization and may limit further marketing of the product based on the results of these post-marketing trials. In addition, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of its products under development.

A sponsor may seek approval of its product candidate under programs designed to accelerate the FDA’s review and approval of new drugs that meet certain criteria. Specifically, new drug products are eligible for Fast TrackFast-Track Designation if they are intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical needs for the condition. For a fast trackfast-track product, the FDA may consider sections of the BLA for review on a rolling basis before the complete application is submitted if relevant criteria are met. A fast track designated product candidate may also qualify for priority review, under which the FDA sets the target date for FDA action on the BLA at six months after the FDA accepts the application for filing. Priority review is granted when there is evidence that the proposed product would be a significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of a serious condition. If criteria are not met for priority review, the application is subject to the standard FDA review period of 10 months after FDA accepts the application for filing. Priority review designation does not change the scientific/medical standard for approval or the quality of evidence necessary to support approval.

Under the accelerated approval program, the FDA may approve a BLA on the basis of either a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. Post-marketing trials or completion of ongoing trials after marketing approval are generally required to verify the biologic’s clinical benefit in relationship to the surrogate endpoint or ultimate outcome in relationship to the clinical benefit. In addition, the U.S. Food and Drug Administration Safety and Innovation Act, which was enacted and signed into law in 2012, established breakthrough therapy designation.BTD. A sponsor may seek FDA designation of its product candidate as a breakthrough therapy if the product candidate is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the therapy may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Sponsors may request the FDA to designate a breakthrough therapy at the time of, or any time after, the submission of an IND, but ideally before an end-of-phase 2 meeting with the FDA. If the FDA designates a breakthrough therapy for a product candidate, it may take actions appropriate to expedite the development and review of the application, which may include holding meetings with the sponsor and the review team throughout the development of the therapy; providing timely advice to, and interactive communication with, the sponsor regarding the development of the drug to ensure that the development program to gather the nonclinical and clinical data necessary for approval is as efficient as practicable; involving senior managers and experienced review staff, as appropriate, in a collaborative, cross-disciplinary review; assigning a cross-disciplinary project lead for the FDA review team to facilitate an efficient review of the development program and to serve as a scientific liaison between the review team and the sponsor; and considering alternative clinical trial designs when scientifically appropriate, which may result in smaller or more efficient clinical trials that require less time to complete and may minimize the number of patients exposed to a potentially less efficacious treatment. Breakthrough designationBTD also allows the sponsor to file sections of the BLA for review on a rolling basis.

Fast Track Designation, priority review and Breakthrough Therapy DesignationBTD do not change the standards for approval but may expedite the development or approval process.

The review and approval process with respect to our drug candidate may also be significantly delayed in the event of government shutdowns, if any.

Post-Approval Requirements

Any products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to record keeping, reporting of adverse experiences, periodic reporting, distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing (as applicable) annual user fee requirements for any marketed products and the establishments at which such products are manufactured, as well as potential new application fees for supplemental applications with clinical data. Drug manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Changes to the manufacturing process are strictly regulated and, depending on the significance of the change, may

15

require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money, and effort in

the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance. We cannot be certain that we or our present or future suppliers will be able to comply with the cGMP regulations and other FDA regulatory requirements. If our present or future suppliers are not able to comply with these requirements, the FDA may, among other things, halt our clinical trials, require us to recall a product from distribution, or withdraw approval of the BLA.

Future FDA and state inspections may identify compliance issues at our facilities or at the facilities of our contract manufacturers that may disrupt production or distribution, or potentially require substantial resources to correct. In addition, discovery of previously unknown problems with a product or the failure to comply with applicable requirements may result in restrictions on a product, manufacturer, or holder of an approved BLA, including withdrawal or recall of the product from the market or other voluntary, FDA-initiated, or judicial action that could delay or prohibit further marketing.

The FDA may withdraw approval of a BLA if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-marketing trials or clinical trials to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

The FDA closely regulates the marketing, labeling, advertising, and promotion of drugs and biologics. A company can make only those claims relating to safety and efficacy that are approved by the FDA and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising, and potential civil and criminal penalties. Physicians may prescribe legally available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s communications on the subject of off-label use of their products.

Government Regulation of Combination Products

Our product candidate under development will be regulated as a combination products,product, which means that they areit is comprised of two or more different components that, if marketed individually, would be subject to different regulatory paths and would require approval of independent marketing applications by the FDA. A combination product, however, is assigned to a center within the FDA that will have primary jurisdiction over its regulation on a determination of the combination product’s primary mode of action, which is the single mode of action that provides the most important therapeutic action. We believe our product candidate includeincludes both a drug and medical device component, and will be regulated as a drug, subject to the review of the FDA’s Center for Drug Evaluation and Research which will have primary jurisdiction over premarket development and approval. The FDA’s Center for Devices and Radiological Health will provide support and review of the inhalernebulizer component of our product candidate.

European Union

MAA

To obtain approval of a drug under the EU regulatory system, an application for a marketing authorization may be submitted under a centralized, a decentralized, or a national procedure. The centralized procedure, which is compulsory for medicines produced by certain biotechnological processes or for orphan drugs, provides for the grant of a single marketing authorization that is valid for all EU member states, which grants the same rights and obligations in each member state as a national marketing authorization. As a general rule, only one marketing authorization may be granted

16

for drugs approved through the centralized procedure and the marketing authorization is also relevant for the EEA countries.

Under the centralized procedure, the Committee for Medicinal Products for Human Use (“CHMP”) is required to adopt an opinion on a valid application within 210 days, excluding clock stops when additional information is to be provided by the applicant in response to questions. On day 120 of the procedure, once the CHMP has received the preliminary assessment reports and opinions from the Rapporteur and Co-Rapporteur designated by the CHMP, it adopts a list of questions, which are sent to the applicant together with the CHMP's overall conclusions. Applicants then have three months to respond (plus an additional three-month extension, if requested). The applicant's replies are assessed, and the assessment report is revised as necessary (and may include a prepared list of outstanding issues). By day 180 of the procedures, the revised assessment report and list of outstanding issues are sent to the applicant together with the CHMP's recommendation. Applicants then have one month to respond to the CHMP (and can request a one or two-month extension). The Rapporteur and Co-Rapporteur assess the applicant's replies and then submit them for review to the CHMP and prepare a final assessment report. Following their evaluation, the CHMP gives a favorable or unfavorable opinion as to whether to grant the marketing authorization. After the adoption of the CHMP opinion, a decision must be adopted by the European Commission, after consulting the Standing Committee of the Member States. The European Commission prepares a draft decision and circulates it to the member states; if the draft decision differs from the CHMP opinion, the Commission must provide detailed explanations. The European Commission adopts a decision within 15 days of the end of the consultation procedure.

Conditional marketing authorizations may be granted for products designated as orphan medicinal products if all of the following conditions are met: (1) the risk-benefit balance of the product is positive, (2) the applicant will likely be in a position to provide the required comprehensive clinical trial data, (3) the product fulfills unmet medical needs, and (4) the benefit to public health of the immediate availability on the market of the medicinal product concerned outweighs the risk inherent in the fact that additional data are still required.

Conditional marketing authorizations are valid for one year, on a renewable basis, until the holder provides a comprehensive data package. Grant of conditional marketing authorization is dependent on the applicant's ability to fulfill the conditions within an agreed upon deadline. Applicants are subject to conditions, including the requirement to complete ongoing studies or to conduct new studies with a view to confirming that the benefit-risk balance is positive or to fulfill specific obligations in relation to pharmacovigilance. Once a comprehensive data package has been supplied, the conditional marketing authorization is replaced by a regular marketing authorization.

Exclusivities

If an approved drug contains a new active substance, it is protected by data exclusivity for eight years from the notification of the Commission decision granting the marketing authorization and then by marketing protection for an additional two or three years. Overall, the drug is protected for ten or eleven years against generic competition, and no additional exclusivity protection is granted for any new development of the active substance it contains.

During the eight-year period of data exclusivity, competitors may not refer to the marketing authorization dossier of the approved drug for regulatory purposes. During the period of marketing protection, competitors may not market their generic drugs. The period of marketing protection is normally two years but may become three years if, during the eight-year data exclusivity period, a new therapeutic indication is approved that is considered as bringing a significant clinical benefit over existing therapies.

Japan

Under the Japanese regulatory system administered by the Ministry of Health, Labor and Welfare (“MHLW”) and the Pharmaceutical and Medical Device Agency (“PMDA”) (which is responsible for product review and evaluations under the supervision of the MHLW), pre-marketing approval and clinical studies are required for all pharmaceutical products. The Law on Securing Quality, Efficacy and Safety of Products Including Pharmaceuticals and Medical Devices (Act No. 145 of 1960) requires a license for marketing authorization when importing to Japan and selling pharmaceutical products manufactured in other countries. It also requires each manufacturing site of a foreign manufacturer to be certified as a manufacturing site of pharmaceutical products to be marketed in Japan.

To receive a license for marketing authorization, the manufacturer or seller must, at the very least, employ certain manufacturing, marketing, quality, and safety personnel. If the quality management methods and post marketing safety management methods applied with respect to the pharmaceutical product fail to conform to the standards stipulated by the MHLWAMHLW license, marketing authorization may not be granted. A company must submit an application for approval to the MHLW with results of nonclinical and clinical studies to show the quality, efficacy, and safety of the product candidate to obtain manufacturing/marketing approval for a new product. A data compliance review, on-site inspection for good clinical practice, and audit and detailed data review for compliance with current good manufacturing practices are

17

undertaken by the PMDA. The committees of the Pharmaceutical Affairs and Food Sanitation Council will discuss each application, and based on the results of these reviews, the final decision on approval is made by the MHLW. The approval process timeline significantly varies, but it can take years. Pricing approval for the product is required in order to be applied for

redemption of health insurance. Once approved and marketable, the medical products are also subject to regular post-marketing vigilance of safety and quality under the standards of Good Manufacturing Practice. In Japan, the National Health Insurance system maintains a Drug Price List specifying which pharmaceutical products are eligible for reimbursement, and the MHLW sets the prices of the products on this list. Upon marketing approval, the manufacturer or seller begins negotiations regarding the reimbursement price with the MHLW, which is generally determined within 60 to 90 days. The government generally introduces price cut rounds every other year and also mandates price decreases for specific products. New products judged innovative or useful, that are indicated for pediatric use, or that target orphan or small population diseases, however, may be eligible for a pricing premium. The government has also promoted the use of generics, where available.

Orphan Drug Status

Under the Orphan Drug Act, the FDA may grant Orphan Drug Designation to drug candidates intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the U.S., or more than 200,000 individuals in the U.S. and for which there is no reasonable expectation that costs of research and development of the drug for the indication can be recovered by sales of the drug in the U.S. Orphan Drug Designation must be requested before submitting a BLA. After the FDA grants Orphan Drug Designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Although there may be some increased communication opportunities, Orphan Drug Designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.

If a drug candidate that has Orphan Drug Designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications, including a full BLA, to market the same drug for the same indication for seven years, except in very limited circumstances, such as if the second applicant demonstrates the clinical superiority of its product or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug for the same disease or condition, or the same drug for a different disease or condition. Among the other benefits of Orphan Drug Designation are tax credits for certain research and a waiver of the BLA application user fee.

Orphan drug exclusivity could block the approval of our drug candidate for seven years if a competitor obtains approval of the same product as defined by the FDA or if our drug candidate is determined to be contained within the competitor’s product for the same indication or disease.

As in the U.S., designation as an orphan drug for the treatment of a specific indication in the EU must be made before the application for marketing authorization is made. Orphan drugs in Europe enjoy economic and marketing benefits, including up to 10 years of market exclusivity for the approved indication unless another applicant can show that its product is safer, more effective, or otherwise clinically superior to the orphan designated product.

The FDA and foreign regulators expect holders of exclusivity for orphan drugs to assure the availability of sufficient quantities of their orphan drugs to meet the needs of patients. Failure to do so could result in the withdrawal of marketing exclusivity for the orphan drug.

Breakthrough Therapy Designation

In December 2019, the FDA granted the use of molgramostim for the treatment of aPAP program Breakthrough Therapy Designation,BTD, which provides a process for expediting the development and review of drug candidates that are intended to treat a serious condition and for which preliminary evidence indicates that the drug candidate may demonstrate substantial improvement over the available therapy.

Other Healthcare Laws and Compliance Requirements

Our sales, promotion, medical education, clinical research, and other activities following product approval will be subject to regulation by numerous regulatory and law enforcement authorities in the U.S. in addition to the FDA, including potentially the Federal Trade Commission, the Department of Justice, the Centers for Medicare and Medicaid Services, other divisions of the U.S. Department of Health and Human Services and state and local governments. Our promotional and scientific/educational programs and interactions with healthcare professionals must comply with the federal Anti-Kickback Statute, the civil False Claims Act (“FCA”), physician payment transparency laws, privacy laws, security laws, and additional federal and state laws similar to the foregoing.

18

The federal Anti-Kickback Statute prohibits, among other things, the knowing and willing, direct or indirect offer, receipt, solicitation or payment of remuneration in exchange for or to induce the referral of patients, including the purchase, order or lease of any good, facility, item or service that would be paid for in whole or part by Medicare, Medicaid or other federal

health care programs. Remuneration has been broadly defined to include anything of value, including cash, improper discounts, and free or reduced-price items and services. The federal Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, formulary managers, and beneficiaries on the other. Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases, or recommendations may be subject to increased scrutiny and review if they do not qualify for an exception or safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct illegal per se under the federal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all its facts and circumstances. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the federal Anti-Kickback Statute has been violated. The government has enforced the federal Anti-Kickback Statute to reach large settlements with healthcare companies based on sham research or consulting and other financial arrangements with physicians. Further, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation. In addition, 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 FCA. Many states have similar laws that apply to their state health care programs as well as private payers.

Federal false claims and false statement laws, including the FCA, impose liability on persons and/or entities that, among other things, knowingly present or cause to be presented claims that are false or fraudulent or not provided as claimed for payment or approval by a federal health care program. The FCA has been used to prosecute persons or entities that “cause” the submission of claims for payment that are inaccurate or fraudulent, by, for example, providing inaccurate billing or coding information to customers, promoting a product off-label, submitting claims for services not provided as claimed, or submitting claims for services that were provided but not medically necessary. Actions under the FCA may be brought by the Attorney General or as a qui tam action by a private individual, or whistleblower, in the name of the government. Violations of the FCA can result in significant monetary penalties and treble damages. The federal government is using the FCA, and the accompanying threat of significant liability, in its investigation and prosecution of pharmaceutical and biotechnology companies throughout the country, for example, in connection with the promotion of products for unapproved uses and other illegal sales and marketing practices. The government has obtained multi-million and multi-billion dollarmulti-billion-dollar settlements under the FCA in addition to individual criminal convictions under applicable criminal statutes. In addition, certain companies that were found to be in violation of the FCA have been forced to implement extensive corrective action plans, and have often become subject to consent decrees or corporate integrity agreements, restricting the manner in which they conduct their business.

The federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) created additional federal criminal statutes that prohibit, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payers; knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services; and willfully obstructing a criminal investigation of a healthcare offense. Like the federal Anti-Kickback Statute, the Affordable Care Act amended the intent standard for certain healthcare fraud statutes under HIPAA such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

Given the significant size of actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating healthcare providers’ and manufacturers’ compliance with applicable fraud and abuse laws. Also, many states have similar fraud and abuse statutes or regulations that may be broader in scope and may apply regardless of payer, in addition to items and services reimbursed under Medicaid and other state programs. Additionally, to the extent that our products, once commercialized, are sold in a foreign country, we may be subject to similar foreign laws.

In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians and other healthcare providers. The Physician Payments Sunshine Act, known as “Open Payments” and implemented as part of the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the Affordable Care Act, among other things, imposed new reporting requirements on certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, for payments or other transfers of value made by them to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate

19

family members. Covered manufacturers are required to collect and report detailed payment data and submit legal attestation to the accuracy of such data to the government each year.

On October 24, 2018, former President Trump signed into law the “Substance Use-Disorder Prevention that Promoted Opioid Recovery and Treatment for Patients and Communities Act” which in part (under a provision entitled “Fighting the Opioid Epidemic with Sunshine”) extends the reporting and transparency requirements under Open Payments to physician assistants, nurse practitioners, and other mid-level practitioners (with reporting requirements going into effect in 2022 for payments made in 2021). Additionally, entities that do not comply with mandatory reporting requirements may be subject to a corporate integrity agreement. Certain states also mandate implementation of commercial compliance programs, impose restrictions on covered manufacturers’ marketing practices and/or require the tracking and reporting of gifts, compensation, and other remuneration to physicians and other healthcare professionals.

We are also subject to data privacy and security regulation by the federal government and the states in which we conduct our business and the EU with the General Data Protection Regulation rules, which became effective in May 2018. HIPAA, as amended by the Health Information Technology and Clinical Health Act (“HITECH”), and their respective implementing regulations, imposes specified requirements on certain health care providers, plans and clearinghouses (collectively, “covered entities”) and their “business associates,” relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s security standards directly applicable to “business associates,” defined as independent contractors or agents of covered entities that create, receive, maintain, or transmit protected health information in connection with providing a service for or on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, certain states have their own laws that govern the privacy and security of health information in certain circumstances, many of which differ from each other and/or HIPAA in significant ways and may not have the same effect, thus complicating compliance efforts.

If our operations are found to be in violation of any of such laws or any other governmental regulations that apply to them, we may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, disgorgement, the curtailment or restructuring of our operations, exclusion from participation in federal and state healthcare programs, imprisonment, contractual damages, reputational harm, and diminished profits and future earnings, any of which could adversely affect our ability to operate our business and our financial results.

In addition to the foregoing health care laws, we are also subject to the U.S. Foreign Corrupt Practices Act (“FCPA”) and similar worldwide anti-bribery laws, which generally prohibit companies and their intermediaries from making improper payments to government officials or private-sector recipients for the purpose of obtaining or retaining business. We have adopted an anti-corruption policy which mandates compliance with the FCPA and similar anti-bribery laws applicable to our business throughout the world. However, we cannot assure that such a policy or procedures implemented to enforce such a policy will protect against intentional, reckless, or negligent acts committed by our employees, distributors, partners, collaborators, or agents. Violations of these laws, or allegations of such violations, could result in fines, penalties or prosecution and have a negative impact on our business, results of operations, and reputation.

Coverage and Reimbursement

Sales of pharmaceutical products depend significantly on the extent to which coverage and adequate reimbursement are provided by third-party payers. Third-party payers include state and federal government health care programs, managed care providers, private health insurers and other organizations. Although we currently believe that third-party payers will provide coverage and reimbursement for our product candidate, if approved, we cannot be certain of this. Third-party payers are increasingly challenging the price, examining the cost-effectiveness, and reducing reimbursement for medical products and services. In addition, significant uncertainty exists as to the reimbursement status of newly approved healthcare products. The U.S. government, state legislatures, and foreign governments have continued implementing cost containment programs, including price controls, restrictions on coverage and reimbursement, and requirements for substitution of generic products. Adoption of price controls and cost containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could limit our net revenue and results. We may need to conduct expensive clinical trials to demonstrate the comparative cost-effectiveness of our products. The product candidate that we develop may not be considered cost-effective and thus may not be covered or sufficiently reimbursed. It is time consuming and expensive for third-party payers to seek coverage and reimbursement. Thus, one payer’s decision to provide coverage and adequate reimbursement for a product does not assure that another payer will provide coverage or that the reimbursement levels will be adequate. Moreover, a payer’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Reimbursement may not be available or sufficient to allow third-party payers to sell our products on a competitive and profitable basis.

Healthcare Reform

The U.S. and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change the healthcare system in ways that could materially affect our ability to sell our products profitably. Among policy makers and payers in the U.S. and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the U.S., the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.

By way of example, in March 2010, the Affordable Care Act was signed into law, intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new 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 of importance to our potential drug candidate are:

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. These changes include, among others, the Budget Control Act of 2011, which mandates aggregate reductions to Medicare payments to providers of up to 2% per fiscal year effective April 1, 2013, and due to subsequent legislative amendments, will remain in effect through 2029 unless additional Congressional action is taken. In January 2013, former President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, further reduced Medicare payments to several providers, including hospitals and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on customers for our product candidate, if approved, and, accordingly, our financial operations.

There have been judicial and Congressional challenges to certain aspects of the Affordable Care Act, and we expect additional challenges and amendments in the future. It is unclear how this such effort to repeal and replace the ACA will impact the healthcare industry or our business operations. Any reduction in reimbursement from Medicare or other government-funded programs may result in a similar reduction in payments from private payers. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our drugs.

Other Foreign Regulations

In addition to regulations mentioned above, we will be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our products to the extent we choose to develop or sell any products outside of the U.S. The approval process varies from country to country and the time may be longer or shorter than that required to

obtain FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing, and reimbursement vary greatly from country to country.

Intellectual Property

We strive to protect the proprietary technology that we believe is important to our business, including our product candidate and our processes. We seek patent protection in the U.S. and internationally for our products, their methods of use and processes of manufacture and any other technology to which we have rights, as appropriate, such as device exclusivity. We also rely on trade secrets that may be important to the development of our business.

We own issued patents and additional pending patent applications worldwide for a proprietary formulation of vancomycin. The patents and pending applications are derived from a PCT application (Pub. No. WO2012159103) entitled Dry Powder Vancomycin Compositions and Associated Methods. In February 2017, the United States Patent and Trademark Office issued United States Patent No. 9,572,774 for Dry Powder Vancomycin Compositions and Associated Methods that will expire no earlier than 2032. We also have corresponding patent applications for vancomycin in different stages of prosecution in other key markets throughout the world. However, in connection with our decision to discontinue the development of the vancomycin program, we have chosen to abandon certain vancomycin-related applications.

Our success will, in part, depend on the ability to obtain and maintain patent and other proprietary rights in commercially important technology, inventions and know-how related to our business, the validity and enforceability of our patents, the continued confidentiality of our trade secrets as well as our ability to operate without infringing the valid and enforceable patents and proprietary rights of third parties. We also rely on continuing technological innovation and in-licensing opportunities to develop and maintain our proprietary position.

We cannot be sure patents will be granted with respect to any of our pending patent applications or with respect to any patent applications we may own or license in the future, nor can we be sure that any of our existing patents or any patents we may own or license in the future will be useful in protecting our technology and products. For this and more comprehensive risks related to our intellectual property, please see Risk Factors—Factors – Risks Related to Our Intellectual Property.

Trade Secrets

In addition to patents, we rely on trade secrets and know-how to develop and maintain our competitive position. For example, significant aspects of our processes and proprietary technology portfolio are based on unpatented trade secrets and know-how. Trade secrets and know-how can be difficult to protect. We seek to protect our proprietary technology and processes, in part, by confidentiality agreements and invention assignment agreements with our employees, consultants, scientific advisors, contractors and commercial partners. These agreements are designed to protect the proprietary information and, in the case of the invention assignment agreements, to grant us ownership of technologies that are developed through a relationship with a third party. While we have confidence in our key individuals, consultants, partner organizations and systems, agreements or security measures may be breached, and there may not be adequate remedies for any breach. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our contractors use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

Competition

The pharmaceutical industry is highly competitive and subject to continuous technological change. Our potential competitors include large pharmaceutical and biotechnology companies, specialty pharmaceutical and generic drug companies, academic institutions, government agencies and research institutions. We believe that key competitive factors affecting the commercial success of our product candidate will be efficacy, safety and tolerability profile, reliability, convenience of dosing, price and reimbursement. Many of our potential competitors, either alone or with their collaboration partners have substantially greater financial, technical, and human resources than us, and significantly greater experience in the discovery and development of product candidate, manufacturing, obtaining FDA and other regulatory approvals of products and the commercialization of those products. Accordingly, our competitors may be faster and more successful in obtaining FDA approval for therapies and achieving widespread market acceptance. Mergers and acquisitions in the pharmaceutical and biotechnology industry may result in even more resources being concentrated among a smaller number of very capable competitors. We anticipate facing intense and increasing competition as new drugs enter the market and advanced technologies become available. Our competitors’ products may be more effective, or more effectively marketed and sold, than any product candidate we may commercialize and may render our therapies obsolete or non-competitive before we can recover development and commercialization expenses.

We are not aware of any other companies developing an inhaled form of GM-CSF. A glycosylated GM-CSF product, sargramostim (Leukine®(Leukine®), is available on the market in the U.S., intendedapproved for IVintravenous or SCsubcutaneous delivery in patients with neutropenia following cancer chemotherapy. Leukine® has not been approved for the treatment of aPAP or any other acute or chronic lung disease but is sometimes used as a pharmacy-compounded product (injectable product compounded for inhalation

22

delivery). The drug substance in Leukine®, sargramostim, has been used in a nonclinical research project conducted by NIH/TRND in collaboration with the University of Cincinnati College of Medicine on the potential application of inhaled GM-CSF as a treatment for aPAP. No clinical trials have been conducted to date under this collaboration project. We are aware of a multicenter clinical trial of inhaled Leukine®, using a standard commercially available nebulizer, which was conducted by a consortium of independent clinical investigators.investigators from the trial conducted in Japan. It is not known to us if this trial, together with other possibly available related clinical or nonclinical information, may be, or will be, used to support a potential new product approval in Japan. If such a new product would be approved and

launched in Japan, we believe it has the potential to present a material competitive threat to the commercial success of molgramostim in Japan. In addition, in November 2018, Partner Therapeutics, Inc., a commercial biotechnology company, was granted Orphan Drug Designation tofor Leukine® for the treatment of PAP by the FDA.

Employees and Human Capital

We are committed to attracting and retaining the best possible talent. As of March 30, 2022,7, 2024, we had 2237 employees as well as several third-party consultants. All employees are located in the U.S. None of our employees are represented by a labor union or covered by a collective bargaining agreement. We consider our relationship with our employees to be good.

Attraction, Development and Retention

We believe our future success will depend in large part on our continued ability to attract and retain highly skilled employees. Our compensation program, including salary, bonus, benefits as well as short and long-term incentives, is designed to help us to attract and retain individuals whose skills are important to our current and long-term success. Our total compensation package is generally positioned within the competitive ranges of our peer market, with differences generally based on tenure, skills, and performance needed to attract and retain key talent. We have also implemented a spot bonus program that allows employees to nominate their colleagues for cash awards in recognition of notable achievements.

We believe that continued professional growth and development are essential to helping our team stay on top of current rules, laws, trends, and events which impact their duties. We seek to develop our employee talent within the organization through access to training, continuous learning programs, and other development initiatives. We foster a culture of empowerment, transparency, and respect.

Diversity and Inclusion

We value diverse backgrounds and viewpoints and are committed to equal opportunity. We aim to recruit, hire, place, develop, compensate, and advance people based on the needs of our organization and the qualifications, performance, skills, and experience of our people. We expect to continue to enhance our workforce diversity and advance the development of diverse talent. We consistently evaluate the opportunity for diversity for both our employee workforce and our board of directors. Upon beginning employment with Savara, all employees receive training on workplace diversity and inclusion.

Health and Safety

The health and safety of our employees is a top priority, and our goal is to provide a safe and healthy work environment for all personnel. In dealing with the COVID-19 pandemic and emerging variants, weWe have provided our employees the ability to work virtuallyremotely in order to best manage business and personal responsibilities and halted non-essential travel. We have enhanced our internal communications with regular “town hall” meetings to ensure connectivity to our workforce. We have set specific guidelines for our employees to follow when they determine they need to use our facilities. These guidelines include, among others, limiting the number of people in our office at one time and social distancing.responsibilities. We will continue to manage this situationour business with a focus towards the safety of our employees.

Item 1A. Risk Factors.

Investment in our common stock involves a high degree of risk and uncertainty. Our business, operating results, growth prospects and financial condition are subject to various risks, many of which are not exclusively within our control, that may cause actual performance to differ materially from historical or projected future performance. We urge investors to consider carefully the risks described below, together with all of the information in this report and our other public filings, before making investment decisions regarding our securities. Each of these risk factors, as well as additional risks not presently known to us or that we currently deem immaterial, could adversely affect our business, operating results, growth prospects or financial condition, as well as the trading price of our common stock, in which case you may lose all or part of your investment.

Risks Related to Development and Commercialization of our Product Candidate

We are substantially dependent upon the clinical, regulatory, and commercial success of our sole product candidate, molgramostim nebulizer solution (molgramostim). If we are unable to successfully complete clinical development of, obtain regulatory approval for, and successfully commercialize molgramostim, our business may be harmed.

The success of our business is dependent on our ability to advance the clinical development of our sole product candidate, molgramostim for the treatment of patients with aPAP. To date, we have never obtained regulatory approvals for or commercialized a product candidate, and we may never be able to develop a marketable product. We are devoting, and expect to continue to devote, substantially all our efforts and financial resources to the development of molgramostim for aPAP, including clinical trials, regulatory approval, and, if approved, commercialization. Our business depends heavily on the successful completion of clinical development and subsequent regulatory approval of molgramostim for aPAP.

We are conducting IMPALA-2, a global Phase 3 pivotal trial designed to compare the efficacy and safety of molgramostim 300 µg administered once daily by inhalation with matching placebo in patients with aPAP. There can be no assurance that the IMPALA-2 pivotal trial will demonstrate with statistical significance that molgramostim is effective for the proposed indication compared to placebo or that it will establish adequate safety. Any failure to do so would adversely impact the potential for regulatory approval of molgramostim. Even if molgramostim demonstrates a statistically significant difference compared to placebo for the primary endpoint, we may not be able to demonstrate differences for our secondary endpoints. Additionally, clinical trial data frequently are susceptible to varying interpretations. Although we may believe the trial demonstrates promising results, regulatory authorities may analyze or weigh trial data differently, resulting in delay or failure to obtain marketing approval or a requirement to conduct confirmatory studies.

We are not permitted to commercialize molgramostim in the U.S. until we receive approval of a BLA, or in any other country until we receive the requisite approvals from the appropriate regulatory authorities. Failure to obtain such approvals could impair our ability to generate revenues from the product candidate, which would have a material adverse effect on our business, operating results, growth prospects or financial condition, as well as the trading price of our common stock.

Given the developmental nature of our product candidate, we are subject to risks associated with initiating, completing, and achieving positive outcomes from our current and future clinical trials, including:

If we successfully complete the necessary clinical trials for our product candidate, our success will be subject to the risks associated with obtaining regulatory approvals, product launch, and commercialization, including:

Many of these clinical, regulatory, and commercial matters are beyond our control and are subject to other risks described elsewhere in this Item 1A, Risk Factors section. Accordingly, we cannot assure that we will be able to advance our product candidate further through final clinical development, or obtain regulatory approval of, commercialize, or generate significant revenue. If we cannot do so, or are significantly delayed in doing so, our business will be materially harmed.

Clinical drug development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development of our product candidate. If development of our product candidate is unsuccessful or delayed, we may be unable to obtain required regulatory approvals and be unable to commercialize our product candidate on a timely basis, if at all.

Pharmaceutical products are subject to stringent regulatory requirements covering quality, safety, and efficacy. Only after successfully completing extensive pharmaceutical development, nonclinical testing, and clinical trials may a product be considered for regulatory approval.

Clinical trials are expensive, difficult to design and implement, the outcome is inherently uncertain, and failure or delay may occur at any time. We may experience a number of unforeseen events that cause our clinical trials not commence or not be completed on schedule, if at all. Clinical trials can be delayed for a variety of reasons, including:

Clinical trials may not begin on time or be completed in the time frames we anticipate and may be costlier than we anticipate for a variety of reasons, including one or more of those described above. The length of time necessary to successfully complete clinical trials vary significantly and is difficult to predict accurately. We may make statements regarding anticipated timing for completion of enrollment in and/or availability of results from our clinical trials, but such predictions are subject to a number of significant assumptions and actual timing may differ materially for a variety of reasons, including patient enrollment rates, length of time needed to prepare raw trial data for analysis and then to review and analyze it, and other factors described above. If we experience delays in the completion of a clinical trial, if a clinical trial is terminated, or if failure to conduct a trial in accordance with regulatory requirements or the trial’s protocol leads to deficient safety and/or efficacy data, the regulatory approval and/or commercial prospects for our product candidate may be harmed, and our ability to generate product revenue will be delayed. In addition, any delays in completing our clinical trials likely will increase our development costs. Further, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials have in the past and may in the future ultimately lead to the denial of regulatory approval of a product candidate. Even if we ultimately commercialize a product candidate, the standard of care may have changed or other therapies for the same indications may have been introduced to the market in the interim and may establish a competitive threat to us or diminish the need for our products.

Failure at any stage of clinical testing is not uncommon and we may encounter problems that would require additional, unplanned trials or cause us to abandon a clinical development program.

In addition, a clinical trial may be suspended or terminated by us, an IRB, a data safety monitoring board, the FDA, or other regulatory authorities due to a number of factors, including:

Changes in governmental regulations and guidance relating to clinical trials may occur and we may need to amend clinical trial protocols to reflect these changes, or we may amend trial protocols for other reasons. Amendments may require us to resubmit protocols to IRBs for re-examination and approval or renegotiate terms with CROs, clinical trial sites, and investigators, all of which may adversely impact the costs or timing of or our ability to successfully complete a trial.

Even if our clinical trials are completed, the results may not be sufficient to obtain regulatory approval for our product candidate. There are significant risks that ongoing and future clinical trials of our product candidate will not be successful. The results of preclinical and early clinical trials may not be predictive of the results of later-stage clinical trials, and the possible lack of standardization across multiple investigative sites may induce variability in the results which can interfere with the evaluation of treatment effects. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier clinical trials, and we cannot be certain that we will not face similar setbacks. For example, the top line results from our IMPALA trial were released by us on June 12, 2019 and did not meet all of the statistical goals and protocol end points. On October 1, 2019, we received a written response from the FDA in connection with a Type C meeting regarding the molgramostim development program for aPAP and results from IMPALA in which the FDA indicated that the data provided did not provide sufficient evidence of efficacy and safety for the treatment of aPAP. Negative or inconclusive results could cause the FDA and other regulatory authorities to require us to repeat or conduct additional clinical trials, which could significantly increase the time and expense associated with development of that product candidate or cause us to elect to discontinue one or more clinical programs.

There is significant uncertainty regarding the regulatory approval process for any investigational new drug. Substantial further testing and validation of our product candidate and related manufacturing processes may be required, and regulatory approval may be conditioned, delayed, or denied, any of which could delay or prevent us from successfully marketing our product candidate and substantially harm our business.

Regulatory approval is required before a pharmaceutical product can be commercially marketed and sold, and various federal and foreign statutes and regulations also govern or materially influence the manufacturing, safety, labeling, storage, record keeping, and marketing of pharmaceutical products. The process of obtaining these approvals and the subsequent compliance with appropriate U.S. and foreign statutes and regulations is time-consuming and requires the expenditure of substantial resources.

Significant uncertainty exists with respect to the regulatory approval process for any investigational new drug, including molgramostim. Regardless of any guidance the FDA or foreign regulatory agencies may provide a drug’s sponsor during its development, the FDA or foreign regulatory agencies retain complete discretion in deciding whether to accept a BLA, or the equivalent foreign regulatory approval submission for filing or, if accepted, whether to approve a BLA. There are many components to a BLA or marketing authorization application submission in addition to clinical trial data. For example, the FDA or foreign regulatory agencies will review the sponsor’s internal systems and processes, as well as those of its CROs, CMOs, and other vendors, related to development of its product candidates, including those pertaining to its clinical studies and manufacturing processes. Before accepting a regulatory approval submission for review or before approving such submission, the FDA or foreign regulatory agencies may request that we provide additional information that may require significant resources and time to generate, and there is no guarantee that our product candidate will be approved for any indication for which we may apply. The FDA or foreign regulatory agencies may choose not to approve a BLA or its equivalent for a variety of reasons, including a decision related to the safety or efficacy data, manufacturing controls or systems, or for any other issues that the agency may identify related to the development of its product candidates. Even if one or more Phase 3 clinical trials are successful in providing statistically significant evidence of the efficacy and safety of the investigational drug, the FDA or foreign regulatory agencies may not consider efficacy and safety data from the submitted trials adequate scientific support for a conclusion of effectiveness and/or safety and may require one or more additional Phase 3 or other trials prior to granting marketing approval. If this were to occur, the overall development cost for the product candidate would be substantially greater and competitors may bring

products to market before us, which could impair our ability to generate revenues from the product candidate, or even seek approval, if blocked by a competitor’s Orphan Drug exclusivity, which would have a material adverse effect on our business, financial condition, and results of operations.

Further, development of our product candidate and/or regulatory approval may be delayed for reasons beyond our control. Regulations or policies may be changed prior to submission of a marketing application that result in delays or require higher hurdles than currently anticipated. These may occur as a result of drug scandals, recalls, or a political environment unrelated to our products. For example, the FDA has granted molgramostim for aPAP Fast Track and BTD, which are each designed to expedite the development and review of certain drugs. If there were a change in FDA policies and we were to lose those designations, it could cause delays in the regulatory review process. Additionally, U.S. federal government shut-downs or budget sequestrations, such as ones that occurred during January 2018 and December 2018 through January 2019, may result in significant reductions to the FDA’s budget, employees, and operations, which may lead to slower response times and longer review periods, potentially affecting our ability to progress development of our product candidate or obtain regulatory approval for our product candidate.

Even if the FDA or foreign regulatory agencies grant approvals for a product candidate, the conditions or scope of the approval(s) may limit successful commercialization of the product candidate and impair our ability to generate substantial sales revenue. For example, molgramostim could be approved with restrictions for use only by patients unresponsive to the current standard of care or the FDA may approve label claims with age restrictions and/or treatment duration limitations. The FDA may limit the label of molgramostim to a subset of patients based on a review of which patient groups had the greatest efficacious response in clinical trials. Such label restriction may be undesirable and may limit successful commercialization. The FDA or foreign regulatory agencies may also only grant marketing approval contingent on the performance of costly post-approval nonclinical or clinical studies, or subject to warnings or contraindications that limit commercialization. Additionally, even after granting approval, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, and recordkeeping for our products will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, and continued compliance with cGMP, good clinical practice ("GCP"), international conference on harmonization regulations, and good laboratories practice ("GLP"), which are regulations and guidelines that are enforced by the FDA or foreign regulatory agencies for all clinical development and for any clinical studies that we conduct post-approval. The FDA or foreign regulatory agencies may decide to withdraw approval, add warnings, or narrow the approved indications in the product label, or establish risk management programs that could restrict distribution of our products. These actions could result from, among other things, safety concerns, including unexpected side effects or drug interaction problems, or concerns over misuse of a product. If any of these actions were to occur following approval, we may have to discontinue commercialization of the product, limit our sales and marketing efforts, implement risk minimization procedures, and/or conduct post-approval studies, which in turn could result in significant expense and delay or limit our ability to generate sales revenues.

Our molgramostim product candidate may cause undesirable side effects or adverse events or have other properties that could delay or prevent our clinical development, regulatory approval, or commercialization.

Undesirable side effects or adverse events caused by our molgramostim product candidate could interrupt, delay, or halt clinical trials and could result in the denial of regulatory approval by the FDA or other regulatory authorities for any or all indications, and in turn prevent us from commercializing our product candidate. A significant challenge in clinical development is that the patient population in early trials, where small numbers of patients are required, is different from the patient population observed in later stage trials, where larger groups of patients are required. As such, efficacy or safety results may differ significantly between trials. If we fail to demonstrate the efficacy of our drug candidate or undesirable side effects occur, they could possibly prevent approval, which would have a material and adverse effect on our business.

If our product candidate receives marketing approval and we or others later identify undesirable side effects caused by the product:

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product or could substantially increase the costs and expenses of commercializing the product, which in turn could delay or prevent us from generating significant revenue from its sale.

Even if we receive regulatory approval for our product candidate, we may face regulatory difficulties that could materially and adversely affect our business, financial condition, and results of operations.

Even if initial regulatory approval is obtained, as a condition to the initial approval, the FDA or a foreign regulatory agency may impose significant restrictions on a product’s indicated uses or marketing or impose ongoing requirements for potentially costly post-approval studies or marketing surveillance programs, any of which would limit the commercial potential of the product. Our molgramostim product candidate also will be subject to ongoing FDA requirements related to the manufacturing processes, labeling, packaging, storage, distribution, advertising, promotion, record-keeping, and submission of safety and other post-market information regarding the product. For instance, the FDA may require changes to approved drug labels, require post-approval clinical studies, and impose distribution and use restrictions on certain drug products. In addition, approved products, manufacturers, and manufacturers’ facilities are subject to continuing regulatory review and periodic inspections. If previously unknown problems with a product are discovered, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, the FDA may impose restrictions on that product or us, including requiring withdrawal of the product from the market. If we or a CMO of ours fail to comply with applicable regulatory requirements, a regulatory agency may:

If our product candidate receives regulatory approval but fails to achieve significant market acceptance among the medical community, patients, or third-party payers, the revenue we generate from its sales will be limited and our business may never achieve profitability.

Our success will depend in substantial part on the extent to which our product candidate, if approved, is accepted by the medical community and patients and reimbursed by third-party payers, including government payers. The degree of market acceptance with respect to our approved product, if any, will depend upon a number of factors, including:

We cannot predict with reasonable accuracy whether physicians, patients, healthcare insurers, health maintenance organizations, or the medical community in general, will accept or utilize our product, if approved. If our product candidate is approved but does not achieve an adequate level of acceptance by these parties, we may not generate sufficient revenue to become or remain profitable. In addition, our efforts to educate the medical community and third-party payers regarding benefits of our product may require significant resources and may never be successful.

If we determine that a product candidate may not achieve adequate market acceptance or that the potential market size does not justify additional expenditures on the program, we may reduce our expenditures on the development and/or the process of seeking regulatory approval of the product candidate while we evaluate whether and on what timeline to move the program forward.

Even if we receive regulatory approval to market our product candidate in the U.S., we may never receive approval or commercialize our product outside of the U.S., which would limit our ability to realize the full commercial potential of our product candidate.

In order to market products outside of the U.S., we must establish and comply with the numerous and varying regulatory requirements of other countries regarding safety and efficacy. Approval procedures vary among countries and can involve additional product testing and validation and additional administrative review periods. The time required to obtain approval in other countries generally differs from that required to obtain FDA approval. The regulatory approval process in other countries may include all of the risks detailed above regarding FDA approval in the U.S., as well as other risks. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in others. Failure to obtain regulatory approval in other countries or any delay or setback in obtaining such approval could have the same adverse effects detailed above regarding FDA approval in the U.S. As described above, such effects include the risks that our product candidate may not be approved for all indications requested, which could limit the uses of our product candidate and have an adverse effect on product sales, and that such approval may be subject to limitations on the indicated uses for which the product may be marketed or require costly, post-marketing follow-up trials.

Risks Related to Our Capital Requirements and Financial Condition

We have incurred significant losses since inception and expect that we will continue to incur losses for the foreseeable future, which makes it difficult to assess our future viability.

We are a clinical development-stage biopharmaceutical company, and we have not been profitable since we commenced operations and may not ever achieve profitability. In addition, we have limited history as an organization and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical industry. Drug development is a highly speculative undertaking and involves a substantial degree of risk. To date, weWe have not obtained any regulatory approvals for a product candidate, commercialized a product candidate, or generated any product revenue. We have devoted significant resources to research and development and other expenses related to our ongoing clinical trials and operations, in addition to acquiring product candidates.

For the year ended December 31, 2021,2023, we incurred a net loss of $43.0$54.7 million, and net cash used in operating activities was $40.1$51.1 million. At December 31, 2021,2023, our cash, cash equivalents and short-term investment securities were approximately $161.2$162.3 million, and working capital was approximately $150.3$155.4 million. At December 31, 2021,2023, we had an accumulated deficit of $300.5$393.4 million. We expect to continue to incur substantial operating losses for the next several years as we seek to advance our molgramostim product candidate through clinical development (IMPALA-2 pivotal trial), global regulatory approvals, and commercialization. No revenue from operations will likely be available until, and unless, our current product candidate, molgramostim, is approved by the FDA or another regulatory agency and successfully marketed, or we enter into an arrangement that provides for licensing revenue or other partnering-related funding, outcomes which we may not achieve. We are also continuously and critically reviewing our liquidity and anticipated capital requirements in light of the uncertainty created by the COVID-19 global pandemic.

We may require additional financing to obtain regulatory approval for molgramostim and a failure to obtain this necessary capital when needed on acceptable terms, or at all, could force us to delay, limit, reduce, or terminate our product development efforts or other operations.

Since our Aravas subsidiary was formed in 2007, most of our resources have been dedicated to the development and acquisition of our product candidates, molgramostim, vancomycin hydrochloride inhalation powder (“vancomycin”), and Apulmiq. On December 10, 2020, based upon our analysis of the clinical data from the Phase 3 trial of vancomycin, we concluded and announced that the trial missed its primary endpoint, ceasing further development of vancomycin. Additionally, as part of our December 2020 pipeline simplification strategy, we discontinued the Apulmiq clinical development program.primarily molgramostim. Our priority remains the continued development of molgramostim for the treatment of aPAP and continued progress in our Phase 3IMPALA-2 pivotal trial. We cannot estimate with reasonable certainty the actual amounts necessary to successfully complete the development and commercialization of our product candidate, and there is no certainty that we will be able to raise the necessary capital on reasonable terms or at all.

24

If adequate funds are not available to us on a timely basis, we will be required to delay, limit, reduce, or terminate our establishment of sales and marketing, manufacturing or distribution capabilities, development activities, other activities that may be necessary to commercialize our product candidate, or conduct preclinical or clinical trials.

Our capital requirements for the foreseeable future will depend in large part on, and could increase significantly as a result of, our expenditures on our development programs. Future expenditures on our development programs are subject to many uncertainties, and will depend on, and could increase significantly as a result of, many factors, including:

Additional capital may not be available when we need it, on terms that are acceptable to us or at all. If adequate funds are not available to us on a timely basis, we will be required to delay, limit, reduce, or terminate our establishment of sales and marketing, manufacturing or distribution capabilities, development activities, other activities that may be necessary to commercialize our product candidate, or conduct preclinical or clinical trials.

If we raise additional capital through marketing and distribution arrangements or other collaborations, strategic alliances, or licensing arrangements with third parties, we may have to relinquish certain valuable rights to our product candidate, technologies, future revenue streams, or research programs or grant licenses on terms that may not be favorable to us. If we raise additional capital through public or private equity offerings, the ownership interest of our stockholders will be diluted, and the terms of any new equity securities may have preferential rights over our common stock. In particular, due to the price per share of our common stock, any sale of our equity securities to raise significant capital would result in substantial ownership dilution to our stockholders. If we raise additional capital through debt financing, it may be subject to

covenants limiting or restricting our ability to take specific actions, such as incurring additional debt or making capital expenditures, or subject to specified financial ratios, any of which could restrict our ability to develop and commercialize our product candidate or operate as a business.

25

Our loan agreement contains covenants which may adversely impact our business; the failure to comply with such covenants could cause our outstanding debt to become immediately payable or accelerate principal payments.

We are a party to aan Amended and Restated Loan and Security Agreement with Silicon Valley Bank, (as amended, thenow a division of First Citizens Bank (the “Amended Loan Agreement”), pursuant to which we have pledged substantially all of our assets, other than our intellectual property (which is subject to a negative pledge). The Amended Loan Agreement includes a number of restrictive covenants, including restrictions on incurring additional debt, making investments, granting liens, disposing of assets, paying dividends, and redeeming or repurchasing capital stock, subject to certain exceptions. Collectively, these restrictive covenants could constrain our ability to grow our business through acquisitions or engage in other transactions. In addition, the Amended Loan Agreement includes covenants requiring, among other things, that we provide financial statements, comply with all laws, pay all taxes, and maintain insurance. The Amended Loan Agreement includes customary events of default, such as our failure to pay amounts due, our failure to comply with covenants, or the occurrence of an event that would reasonably be expected to have a material adverse event on our business. Upon the occurrence and during the continuation of an event of default, Silicon Valley Bank could declare all outstanding loans under the Amended Loan Agreement immediately due and payable and exercise remedies against us and the collateral. Such an event would have a material adverse effect on our liquidity, financial condition, operating results, business, and prospects and cause the price of our common stock to decline.
Refer to Note 7. Debt Facility of the consolidated financial statements in this annual report on Form 10-K for additional discussion.

Any future acquisitions that we make could disrupt our business and harm our financial condition.

We may, from time to time, evaluate potential strategic acquisitions of complementary businesses, products, or technologies. In addition, we may evaluate joint ventures, licensing opportunities, and other collaborative projects. We may not be able to identify appropriate acquisition candidates or strategic partners, or successfully negotiate, finance, or integrate acquisitions of any businesses, products, or technologies. Furthermore, the integration of any acquisition and management of any collaborative project may divert our management’s time and resources from our core business and disrupt our operations. Any cash acquisition we pursue would diminish the funds otherwise available to us for other uses. Any acquisition using our stock would dilute our stockholders’ ownership interests.

If we engage in acquisitions of companies, products, or technologies in order to execute our business strategy, we may need to raise additional capital. We may raise additional capital in the future through one or more financing vehicles that may be available to us including (i) new collaborative agreements; (ii) expansions or revisions to existing collaborative relationships; (iii) private financings; (iv) other equity or debt financings; (v) monetizing assets; and/or (vi) the public offering of securities.

If we are required to raise additional capital in the future, it may not be available on favorable financing terms within the time required, or at all. If additional capital is not available on favorable terms when needed, we will be required to raise capital on adverse terms or significantly reduce operating expenses through the restructuring of our operations or deferral of strategic business initiatives. If we raise additional capital through a public offering of securities, or equity, a substantial number of additional shares may be issued, which may negatively affect our stock price and these additional shares will dilute the ownership interest of our current investors.

We have IPR&D and future impairment of IPR&D may have an adverse impact on our future financial condition and results of operations. Our goodwill was fully impaired during the year ended December 31, 2019.

As of December 31, 2021,2023, we had IPR&D of approximately $11.3$11.0 million. Our intangible assets have been previously impaired and remain subject to additional impairment analyses whenever an event or change in circumstances indicates the carrying amount of such an asset may not be recoverable. We test our goodwill, if any,recoverable and IPR&D for impairmentis tested annually or more frequently if an event or change in circumstances indicates that the asset may be impaired. If an impairment is identified, we would be required to record an impairment charge with respect to the impaired asset to our consolidated statements of operations and comprehensive loss. A significant impairment charge could have a material negative impact on our financial condition and results of operations. We will continue to evaluate our intangible assets for potential impairment in accordance with our accounting policies.

September 30. Events giving rise to impairment are difficult to predict and are an inherent risk in the pharmaceutical industry. Some of the potential risks that could result in impairment of our IPR&D include negative clinical trial results, adverse regulatory developments, delay or failure to obtain regulatory approval, additional development costs, changes in the manner of our use or development of our product candidate, competition, earlier than expected loss of exclusivity, pricing pressures, higher operating costs, geopolitical conflicts, changes in tax laws, prices that third parties are willing to pay for our IPR&D or similar assets in an arm’s-length transaction being less than the carrying value of our IPR&D, and other adverse market and economic environment changes or trends, such as the ultimate scope and scale of the COVID-19 global pandemic and the impact of COVID-19 on patient enrollment in our IMPALA-2 trial.trends. Events or changes in circumstances may lead to significant impairment

26

charges on our IPR&D in the future, which could materially adversely affect our financial condition and results of operations.

Adverse developments affecting financial institutions, companies in the financial services industry, or the financial services industry generally, such as actual events or concerns involving liquidity, defaults, or non-performance, could adversely affect our operations and liquidity.

Actual events involving limited liquidity, defaults, non-performance, or other adverse developments that affect financial institutions or other companies in the financial services industry, or the financial services industry generally, or concerns or rumors about any such events, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, the Federal Deposit Insurance Corporation ("FDIC") took control of Silicon Valley Bank, where the Company maintains depository accounts and has a debt facility, and created the National Bank of Santa Clara to hold the deposits of Silicon Valley Bank after Silicon Valley Bank was unable to continue its operations. On March 27, 2023, First Citizens BancShares, Inc. (Nasdaq: FCNCA) announced that it had entered into an agreement with the FDIC to purchase all of the assets and liabilities of Silicon Valley Bank and all bank deposits.

Although the failure of Silicon Valley Bank did not cause us to experience any material impacts on our financial condition or results of operations, our access to our cash and cash equivalents in amounts adequate to finance our operations could be significantly impaired if the financial institutions with which we have arrangements face liquidity constraints or failures. In addition, investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Any material decline in available funding or our ability to access our cash and cash equivalents could adversely impact our ability to meet our operating expenses, result in breaches of our contractual obligations, or result in violations of federal or state wage and hour laws, any of which could have material adverse impacts on our operations and liquidity.

Risks Related to Our Business Strategy and OperationsDependence on Third Parties

We are substantially dependent upon the clinical, regulatory, and commercial success of our product candidate, molgramostim. Clinical drug development involves a lengthy and expensive process with an uncertain outcome, results of earlier studies and trials may not be predictive of future trial results, and our clinical trials may fail to adequately demonstrate to the satisfaction of regulatory authorities the safety and efficacy of our molgramostim product candidate.

The success of our business is dependent on our ability to advance the clinical development of molgramostim for the treatment of patients with aPAP.

Clinical development is expensive, can take many years to complete, and its outcome is inherently uncertain. A failure of one or more of our clinical trials can occur at any time during the clinical trial process as demonstrated by the results of our IMPALA trial 2019 and AVAIL trial in 2020. The results of preclinical and early clinical trials of our product candidate may not be predictive of the results of later-stage clinical trials. There is a high failure rate for drugs proceeding through clinical trials, and product candidates in later stages of clinical trials may fail to show the required safety and efficacy despite having progressed through preclinical and initial clinical trials. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier clinical trials, and we cannot be certain that we will not face similar setbacks. Even if our clinical trials are completed, the results may not be sufficient to obtain regulatory approval for our product candidate.

Given the developmental nature of our product candidate, we are subject to risks associated with initiating, completing, and achieving positive outcomes from our current and future clinical trials, including:

If we successfully complete the necessary clinical trials for our product candidate, our success will be subject to the risks associated with obtaining regulatory approvals, product launch, and commercialization, including:

27

Many of these clinical, regulatory, and commercial matters are beyond our control and are subject to other risks described elsewhere in this Risk Factors section. Accordingly, we cannot assure that we will be able to advance our product candidate further through final clinical development, or obtain regulatory approval of, commercialize, or generate significant revenue. If we cannot do so, or are significantly delayed in doing so, our business will be materially harmed.

Additionally, as we continue to advance the IMPALA-2 trial, there remains a general uncertainty regarding the impact of COVID-19 and emerging variants on the aPAP patient population and physicians. Patients suffering from aPAP are prone to underlying lung conditions and are often treated by infectious disease specialists and pulmonologists. These treating physicians are on the front lines in addressing this global pandemic and must now, understandably, focus their attention on COVID-19. Further, if an aPAP patient enrolled in the trial were to contract COVID-19, they may need to discontinue their participation.

If we fail to attract and retain senior management and key scientific personnel, we may be unable to successfully develop and commercialize our product candidate.

We have historically operated with a limited number of employees that manage third parties for most development activities. Institutional knowledge is concentrated within a small number of employees. Our success depends on our continued ability to attract, retain, and motivate highly qualified management, clinical, and scientific personnel. Our future success is highly dependent upon the contributions of our senior management, as well as our senior scientists and other members of our senior management team. The loss of services of any of these individuals, who all have at-will employment arrangements with us, could delay or prevent the successful development of our product pipeline, completion of our planned clinical trials, or the commercialization of our product candidate.

Replacing key employees may be a difficult, costly, and protracted process, and we may not have other personnel with the capacity to assume all the responsibilities of a key employee upon his/her departure. Transition periods can be difficult to manage and may cause disruption to our business.

In addition, there may be intense competition from other companies and organizations for qualified personnel. Other companies and organizations with which we compete for personnel may have greater financial and other resources and different risk profiles than us, and a history of successful development and commercialization. If we cannot attract and retain skilled personnel, as needed, we may not achieve our development and other goals.

The success of our business will depend on our ability to develop and maintain relationships with respected service providers and industry-leading consultants and advisers. If we cannot develop and maintain such relationships as needed, the rate and success at which we can develop and commercialize our product candidate may be limited. In addition, our outsourcing strategy, which has included engaging consultants that spend considerable time to manage key functional areas, may subject us to scrutiny under labor laws and regulations, which may divert management time and attention and have an adverse effect on our business and financial condition.

The COVID-19 global pandemic has required us to adapt our operations, such as enabling employees to work remotely, which may adversely affect their employment satisfaction or productivity.

We do not have, and do not have plans to, establish commercial manufacturing facilities. We completely rely on third parties for the manufacture and supply of our clinical trial drug and delivery device supplies and, if approved, commercial product materials. The loss of any of these vendors or a vendor’s failure to provide us with an adequate supply of clinical trial or commercial product material in a timely manner and on commercially acceptable terms, or at all, could harm our business.

We outsource the manufacture of our molgramostim product candidate and do not plan to establish our own manufacturing facilities. To manufacture our product candidate, we have made numerous custom modifications at CMOs, making us highly dependent on these CMOs. For clinical and commercial supplies, if approved, we have supply agreements with third party CMOs for drug substance, finished drug product, drug delivery devices and other necessary

28

components of our molgramostim product candidate. While we have secured long-term commercial supply agreements with many of the third party CMOs, we would need to negotiate agreements for commercial supply with several important CMOs, and we may not be able to reach agreement on acceptable terms. In addition, we rely on these third parties to conduct or assist us in key manufacturing development activities, including qualification of equipment, developing and validating methods, defining critical process parameters, releasing component materials, demonstrating comparability of DS and DP, and conducting stability testing, among other things. If these third parties are unable to perform their tasks successfully in a timely manner, whether for technical, financial, or other reasons, we may be unable to secure clinical trial material, or commercial supply material if approved, which likely would delay the initiation, conduct, or completion of our clinical trials or prevent us from having enough commercial supply material for sale, which would have a material and adverse effect on our business. For example, the impacts of the current COVID-19 global pandemic are evolving. There have been and could be additional delays in the manufacturing supply chain for our product candidate, including delays in procurement of materials for certain of our clinical trials, due to the outbreak,potentially resulting in delays in clinical trials and recruitment. Further, we have experienced an increase in costs associated with the supply chain disruption. The extent to which the pandemic impactscircumstances such as global health threats, global conflicts, and social unrest impact our ability to procure sufficient supplies for the development and commercialization of our product candidate going forward will depend on the severity and duration of the spread of COVID-19such circumstances. For example, our primary CMO for drug substance operates in Argentina, which is experiencing high inflation, a weakening currency, labor strikes and emerging variantssocial and the actions undertaken to contain the pandemicpolitical unrest. Those conditions could result in supply chain disruptions or treat its effects.increased costs.

All manufacturers of our clinical trial material and, if approved, commercial product, including drug substance manufacturers, must comply with cGMP requirements enforced by the FDA through its facilities inspection program and applicable requirements of foreign regulatory authorities. These requirements include manufacturing, quality control, quality assurance, and the maintenance of records and documentation. Manufacturers of our clinical trial material may be unable to comply with these cGMP requirements and with other FDA, state, and foreign regulatory requirements. While we and our representatives generally monitor and audit our manufacturers’ systems, we do not have full control over their ongoing compliance with these regulations. Although the responsibility to maintain cGMP compliance is shared between us and thea requirement of third-party manufacturer,manufacturers, we bear ultimate responsibility for our supply chain and compliance with regulatory standards. Failure to comply with these requirements may result in fines and civil penalties, suspension of production, suspension or delay or failure to obtain product approval, product seizure or recall, or withdrawal of product approval.

Currently, we do not have alternative vendors to back up our primary vendors of clinical trial material or, if approved, commercial supply material.

Identification of and discussions with otheralternative vendors, if necessary, may be protracted and/or unsuccessful, or these new vendors may be unsuccessful in producing the same results as the current primary vendors producing the material. Therefore, if our primary and back-up vendors become unable or unwilling to perform their required activities, we could experience protracted delays or interruptions in the supply of clinical trial material and, ultimately, product for commercial sale, which would materially and adversely affect our development programs, commercial activities, operating results, and financial condition. In addition, the FDA or regulatory authorities outside of the U.S. may require that we have an alternate manufacturer of a drug product before approving it for marketing and sale in the U.S. or abroad and securing such alternate manufacturer before approval of a BLA could result in considerable additional time and cost prior to BLA approval. We are pursuing but have not yet engaged a second source manufacturer for molgramostim.

Any new manufacturer or supplier of finished drug product or its component materials, including drug substance and delivery devices, would be required to qualify under applicable regulatory requirements and would need to have sufficient rights under applicable intellectual property laws to the method of manufacturing of such product or ingredients required by us. The FDA or foreign regulatory agency may require us to conduct additional clinical trials, collect stability data, and provide additional information concerning any new supplier, or change in a validated manufacturing process, including scaling-up production, before we could distribute products from that manufacturer or supplier or revised process. For example, if we were to engage a third party other than our current CMOs to supply the drug substance or drug product for future clinical trials or commercial sale, the FDA or regulatory authorities outside of the U.S. may require us to conduct additional clinical and nonclinical studies to ensure comparability of the drug substance or drug product manufactured by our current CMOs to that manufactured by the new supplier. Changing of suppliers or equipment is particularly challenging for companies like us, with inhalation products, because any change could alter the performance of the drug product.

The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of pharmaceutical products often encounter difficulties in production, particularly in scaling-up initial production. These problems include difficulties with production costs and yields, quality control, including stability of the product candidate and quality assurance testing, and shortages of qualified personnel. Our product candidate has not been manufactured at the scale we believe will be necessary to maximize its commercial value and, accordingly, after initial licensure and commercialization, we may encounter difficulties in attempting to scale-up production and may not succeed in that effort on a timely basis or at all. In addition, the FDA or other regulatory authorities may impose additional requirements as we scale up initial production capabilities, which may delay our scale-up activities and/or add expense.

If our manufacturers encounter any of the aforementioned difficulties or otherwise fail to comply with their contractual obligations or there are delays entering commercial supply agreements due to capital constraints, we may have

29

insufficient quantities of material to support ongoing and/or planned clinical trials or to meet commercial demand, if approved. In addition, any delay or interruption in the supply of materials necessary or useful to manufacture our product candidate could delay the completion of our clinical trials, increase the costs associated with our development programs, and depending upon the period of delay, require us to commence new clinical trials at significant additional expense or terminate the trials completely. Delays or interruptions in the supply of commercial product could result in increased cost of goods sold and lost sales. We cannot provide assurance that manufacturing or quality control problems will not arise in connection with the manufacture of our clinical trial material or commercial product, if approved, or that third-party manufacturers will be able to maintain the necessary governmental licenses and approvals to continue manufacturing such clinical trial material or commercial product, as applicable. In addition, molgramostim is currently manufactured entirely outside the U.S. and, as a result, we may experience interruptions in supply due to shipping or customs difficulties or regional instability. Furthermore, changes in currency fluctuations, shipping costs, or import tariffs could adversely affect cost of goods sold. Any of the above factors could cause us to delay or suspend anticipated or ongoing trials, regulatory submissions, or commercialization of our product candidate, entail higher costs, or result in being unable to effectively commercialize our product. Our dependence upon third parties for the manufacture of our clinical trial material may adversely affect our future costs and our ability to develop and commercialize our product candidate on a timely and competitive basis.

We rely significantly on third parties to conduct our nonclinical testing and clinical trials and other aspects of our molgramostim development program, and if those third parties do not satisfactorily perform their contractual obligations or meet anticipated deadlines, the development of our molgramostim product candidate could be adversely affected.

We do not employ personnel or possess the facilities necessary to conduct many of the activities associated with our programs. We engage consultants, advisors, CROs, and others to assist in the design and conduct of nonclinical and clinical trials of our product candidate, with interpretation of the results of those trials, and with regulatory activities, and we expect to continue to outsource all or a significant amount of such activities. Specifically, in early 2021,For example, we have engaged a CRO, Parexel, to support our IMPALA-2 pivotal clinical trial development activities. As a result, manyactivities, and we are substantially dependent upon Parexel for the conduct of the IMPALA-2 pivotal trial. Many important aspects of our development programs are and will continue to be outside our direct control, and our third-party service providers may not perform their activities as required or expected, including the maintenance of good clinical practice (“GCP”), good laboratories practice (“GLP”),GCP, GLP, and cGMP compliance, which are ultimately our responsibility to ensure. Further, such third parties may not be as committed to the success of our programs as our own employees and, therefore, may not devote the same time, thoughtfulness, or creativity to completing projects or problem-solving as our own employees would. To the extent we are unable to successfully manage the performance of third-party service providers, our business may be adversely affected.

The CROs that we engage to execute our clinical trials play a significant role in the conduct of the trials, including patient enrollment and the collection and analysis of trial data. We likely will depend on CROs and clinical investigators to conduct future clinical trials and to assist in analyzing data from completed trials and developing regulatory strategies for our product candidate. Individuals working at the CROs with which we contract, as well as investigators at the sites at which our trials are conducted, are not our employees, and we have limited control over the amount or timing of resources that they devote to their programs. In addition, our CROs may be affected by business or workforce interruptions for many reasons including as a result of an outbreak of COVID-19, emerging variants, or another infectious disease, over which they and we have limited control. If our CROs, trial investigators, and/or third-party sponsors fail to

devote sufficient time and resources to trials of our product candidate, if we and/or our CROs do not comply with all GLP and GCP regulatory and contractual requirements, or if their performance is substandard, we may delay commencement and/or completion of these trials, submission of applications for regulatory approval, regulatory approval, and commercialization of our product candidate. Failure of CROs to meet their obligations to us could adversely affect development of our product candidate.

In addition, CROs we engage may have relationships with other commercial entities, some of which may compete with us. Through intentional or unintentional means, our competitors may benefit from lessons learned on our projects that could ultimately harm our competitive position. Moreover, if a CRO fails to properly, or at all, perform our activities during a clinical trial, we may not be able to enter into arrangements with alternative CROs on acceptable terms or in a timely manner, or at all. Switching CROs may increase costs and divert management time and attention. In addition, there likely would be a transition period before a new CRO commences work. These challenges could result in delays in the commencement or completion of our clinical trials, which could materially impact our ability to meet our desired and/or announced development timelines and have a material adverse impact on our business and financial condition.

Our molgramostim product candidate may cause undesirable side effects or adverse events or have other properties that could delay or prevent our clinical development, regulatory approval, or commercialization.

Undesirable side effects or adverse events caused by our molgramostim product candidate could interrupt, delay, or halt clinical trials and could result in the denial of regulatory approval by the FDA or other regulatory authorities for any or all

indications, and in turn prevent us from commercializing our product candidate. A significant challenge in clinical development is that the patient population in early trials, where small numbers of patients are required, is different from the patient population observed in later stage trials, where larger groups of patients are required. For example, patients in earlier stage trials may be more sick, compliant, or otherwise motivated than patients in larger trials. As such, efficacy or safety results may differ significantly between trials. If we fail to demonstrate the efficacy of our drug candidate or undesirable side effects occur, they could possibly prevent approval, which would have a material and adverse effect on our business.

If our product candidate receives marketing approval and we or others later identify undesirable side effects caused by the product:

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product or could substantially increase the costs and expenses of commercializing the product, which in turn could delay or prevent us from generating significant revenue from its sale.

We may not achieve our projected development goals in the time frames we have announced.

We have set goals for accomplishing certain objectives material to the successful development of our molgramostim product candidate. The actual timing of these events may vary due to many factors, including delays or failures in our nonclinical testing, clinical trials, and manufacturing and regulatory activities and the uncertainties inherent in the regulatory approval process. From time to time, we create estimates for the completion of enrollment of or announcement of data from clinical trials of our product candidate. However, predicting the rate of enrollment or the time from completion of enrollment to announcement of data for any clinical trial requires us to make significant assumptions that may prove to be incorrect. Our estimated enrollment rates and the actual rates may differ materially, and the time required to complete enrollment of any clinical trial may be considerably longer than we estimate. Such delays may adversely affect our financial condition and results of operations.

Even if we complete a clinical trial with successful results, we may not achieve our projected development goals in the time frames we initially anticipate or announce. If a development plan for a product candidate becomes more extensive and costly than anticipated, we may determine that the associated time and cost are not financially justifiable and, as a result, may discontinue development in a particular indication or of the product candidate as a whole. In addition, even if a trial did complete with successful results, changes may occur in regulatory requirements or policy during the period of product development and/or regulatory review of a BLA that relate to the data required to be included in BLAs, which may require additional studies that may be costly and time consuming. Any of these actions may be viewed negatively, which could adversely impact our financial condition.

Further, throughout development, we must provide adequate assurance to the FDA and other regulatory authorities that we can consistently develop and produce our product candidate in conformance with GLP, GCP, cGMP, and other regulatory standards. As discussed above, we rely on CMOs for the manufacture of clinical, and future commercial, quantities of our product candidate. If future FDA or other regulatory authority inspections identify cGMP compliance deficiencies at these third-party facilities, production of our clinical trial material or, in the future, commercial product, could be disrupted, causing potentially substantial delay in or failure of development or commercialization of our product candidate.

We are substantially dependent upon our primary CRO, Parexel, for conducting our IMPALA-2 clinical trial.

We do not employ personnel or possess the facilities necessary to conduct many of the activities associated with our IMPALA-2 clinical trial. We have engaged a CRO, Parexel, to assist in the conduct of the trial. As a result, many important aspects of our development programs are, and will, continue to be outside our direct control. Parexel may not perform their activities as required or expected, including the maintenance of GCP and GLP. Further, Parexel may not be as committed to the success of our program as our own employees would. To the extent we are unable to successfully manage the performance of Parexel, our business may be adversely affected.

Our employees, independent contractors and consultants, principal investigators, CROs, CMOs, other vendors, and any future commercial partners may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could cause significant liability for us and harm our reputation.

We are exposed to the risk that our employees, independent contractors and consultants, principal investigators, CROs, CMOs, other vendors, and any future commercial partners may engage in fraudulent conduct or other misconduct, including intentional failures to comply with FDA regulations or similar regulations of comparable foreign regulatory authorities, to provide accurate information to the FDA or comparable foreign regulatory authorities, to comply with manufacturing standards required by cGMP or our standards, to comply with federal and state healthcare fraud and abuse laws and regulations and similar laws and regulations established and enforced by comparable foreign regulatory authorities, and to report financial information or data accurately or disclose unauthorized activities to them. The misconduct of our employees and other service providers could involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. Although we have adopted a code of business conduct and ethics, it is not always possible to identify and deter such 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 or our service providers, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and results of operations, including the imposition of significant fines or other sanctions. For example, if one of our manufacturing partners were placed under a consent decree, we may be hampered in our ability to manufacture clinical or commercial supplies.

The company intends to establish a redundant supply chain with second sources of drug substance and drug product manufacture. If the product manufactured at the second sources of manufacture is not demonstrated to be comparable with materials used in the clinical program, we may not be able to commercialize from these second sources.

Our operations might be interrupted

We have engaged third-parties for our drug product and financial resultsdrug substance manufacturing to serve as second source manufacturers and suppliers of molgramostim to attain uninterrupted supply and mitigate approvability risk. If the second sources do not demonstrate the ability to provide comparable product to our primary sources, the supply chain and scalability to commercialize molgramostim could be adversely impactedimpacted.

Any new manufacturer or supplier would be required to qualify under applicable regulatory requirements and would need to have sufficient rights under applicable intellectual property laws to the method of manufacturing of such product or ingredients required by us. The FDA or foreign regulatory agency may require us to conduct additional clinical trials, collect stability data, and provide additional information concerning any new supplier, or change in a validated manufacturing process, including scaling-up production, before we could distribute products from that manufacturer or supplier or revised process. For example, if we were to engage a third party other than our current CMOs to supply the drug substance or drug product for future clinical trials or commercial sale, the FDA or regulatory authorities outside of the U.S. may require us to conduct additional clinical and nonclinical studies to ensure comparability of the drug substance or drug product manufactured by our current CMOs to that manufactured by the occurrencenew supplier. Changing of a natural disaster, actssuppliers is particularly challenging for companies like us, with inhalation products, because any change could alter the performance of war or terrorism, system malfunction, telecommunication and electrical failures or other catastrophic event, or public health crises, such as a pandemic (e.g. COVID-19).the drug product.

Risks Related to Competition, Retaining Key Employees and Managing Growth

Molgramostim has received Orphan Drug Designation from the FDA and the EMA. If a commercial facility in Austin, Texas, USA. Important documentscompetitor obtains Orphan Drug exclusivity for a product with the same active ingredient and records, including copiesroute of our regulatory documents and other recordsdelivery as molgramostim for aPAP, we may be unable to market our product candidate until the exclusivity of the competing product expires.

Molgramostim has received Orphan Drug Designation in the U.S. by the FDA and in Europe by the EMA for the treatment of aPAP. If approval is received to market molgramostim, the FDA will not approve a similar product, with the same active ingredient, to molgramostim for seven years and the EMA will not approve a similar product to molgramostim for ten years, unless we are located both atunable to produce enough supply to meet demand in the marketplace or another similar product, with the same active ingredient, is deemed clinically superior. Similar product candidates, with the same active ingredient and route of delivery, may be granted Orphan Drug Designation during the development, but the Orphan Drug exclusivity is granted only to the first of such products approved, which means there is risk that a secure offsite document storage facilitycompetitor product candidate may receive approval and Orphan Drug exclusivity before us, thus preventing us from marketing our product candidate until the exclusivity of the competing product expires. Also, the Orphan Drug status will not prevent a competitor with a different active ingredient from competing with our product candidate. If we are prevented from marketing molgramostim for aPAP due to a competitor’s Orphan Drug exclusivity, it would have a material adverse effect on our business.

We expect competition in the marketplace for our molgramostim product candidate should it receive regulatory approval.

The development and commercialization of new drug products is highly competitive and subject to rapid and significant change. Developments by others may render potential application of our molgramostim product candidate in aPAP obsolete or noncompetitive, even prior to completion of its development and approval. If successfully developed and approved, we expect our product candidate will face competition. We may not be able to compete successfully against organizations with competitive products, particularly large pharmaceutical companies. Many of our potential competitors have significantly greater financial, technical, and human resources than us, and may be better equipped to develop, manufacture, market, and distribute products. Many of these companies operate large, well-funded research, development, and commercialization programs, have extensive experience in nonclinical and clinical trials, obtaining FDA and other regulatory approvals and manufacturing and marketing products, and have multiple products that have been approved or are in late-stage development. These advantages may enable them to receive approval from the FDA or any foreign regulatory agency before us and prevent us from competing due to their orphan drug protections. Smaller companies may also prove to be significant competitors, particularly through collaborative arrangements with large pharmaceutical and biotechnology companies. Furthermore, heightened awareness on the part of academic institutions, government agencies, and other public and private research organizations of the potential commercial value of their inventions have led them to actively seek to commercialize the technologies they develop, which increases competition for investment in our programs. Competitive products may be more effective, easier to dose, or more effectively marketed and sold than ours, which would have a material adverse effect on our ability to generate revenue.

Although we are not aware of any companies developing an inhaled form of GM-CSF for the treatment of aPAP, Leukine® (sargramostim), a yeast-derived recombinant human granulocyte-macrophage colony stimulating factor, rhu-GM-CSF, which is a product of Partner Therapeutics, Inc., is being pharmacy-compounded and utilized by some patients for the off-label treatment of aPAP. Additionally, Partner Therapeutics, Inc. is working with the Pharmaceuticals and Medical Devices Agency and the MHLW in Japan for regulatory approval of Leukine® for the treatment of aPAP. We cannot assess the likelihood of formal regulatory approval of Leukine®, the effectiveness of its off-label administration to patients with aPAP, or the number of aPAP patients using Leukine® for the pharmacy-compounded off-label treatment. If Leukine® were to receive formal regulatory approval in Japan, we believe it has the potential to present a material competitive threat to the commercial success of molgramostim in Japan, which could have a material adverse effect on our business.

If we fail to attract and retain senior management and key scientific personnel and develop and maintain relationships with service providers, consultants and advisers, we may be unable to successfully develop and commercialize our product candidate.

We have historically operated with a limited number of employees that manage third parties for most development activities. Institutional knowledge is concentrated within a small number of employees. Our success depends on our continued ability to attract, retain, and motivate highly qualified management, clinical, and scientific personnel. Our future success is highly dependent upon the contributions of our senior management, as well as at our own facilities,senior scientists and other members of our senior management team. The loss of services of any of these individuals, who all have at-will employment arrangements with us, could delay or prevent the successful development of our product pipeline, completion of our planned clinical trials, or the commercialization of our product candidate.

Natural disastersa key employee upon his/her departure. Transition periods can be difficult to manage and other catastrophic events, such as wildfires and other fires, earthquakes and extended power interruptions, public health crises, severe weather conditions, or acts of war or terrorism, such as the conflict between Russia and Ukraine, could significantly disrupt our operations and result in additional, unplanned expense. Any natural disaster or catastrophic event could disrupt our business operations and result in setbacksmay cause disruption to our development programs. Even though we believe we carry commercially reasonable insurance, we might suffer losses that are not covered by or exceed the coverage available under these insurance policies.business.

In addition, our operationsthere may be adversely impacted by international conflict. For example, tensions between Ukraineintense competition from other companies and Russiaorganizations for qualified personnel. Other companies and organizations with which we compete for personnel may have escalated in recent months, culminating in Russia’s recent invasiongreater financial and other resources and different risk profiles than us, and a history of Ukraine. successful development and commercialization. If we cannot attract and retain skilled personnel, as needed, we may not achieve our development and other goals.

The political and physical conditions in Ukraine and Russia, as well as in neighboring countries, may disruptsuccess of our supply chain and increase our costs, which may adversely affectbusiness will depend on our ability to conduct ongoing clinical trialsdevelop and impact patients’ abilitymaintain relationships with respected service providers and industry-leading consultants and advisers. If we cannot develop and maintain such relationships as needed, the rate and success at which we can develop and commercialize our product candidate may be limited. In addition, our outsourcing strategy, which has included engaging consultants that spend considerable time to partake in our clinical trials. While we do not believe this conflict willmanage key functional areas, may subject us to scrutiny under labor laws and regulations, which may divert management time and attention and have a material impact on our current operations, given the rapidly evolving situation and the potential to expand beyond Ukraine and Russia, the full impact of the conflict remains uncertain.

During the first quarter of 2020, COVID-19 was declared a pandemic by the World Health Organization, resulting in significant disruptions to U.S. and international manufacturing and supply chains or operations as well as travel restrictions in the U.S. and many other countries. Global supply chain disruptions have resulted in delays and increased costs associated with the goods. While the continued impact of the current COVID-19 pandemic and emerging variantsan adverse effect on our business and financial results is uncertain, the COVID-19 pandemic has had a negative impact on our business, financial condition, and operating results. There have been and could be additional delays in the manufacturing supply chain for our product candidate, including delays in procurement of materials for certain of our clinical trials due to the outbreak, delays in clinical trials and recruitment. Further, we have experienced an increase in costs associated with the supply chain disruption. In a more severe scenario, our business, financial condition, and operating results could be more significantly affected. Given the dynamic nature of these circumstances, the impact of potential future disruptions of the manufacturing and supply chain associated with the COVID-19 pandemic and emerging variants is difficult to predict.condition.

We currently have limited marketing capabilities and no sales organization. If we are unable to establish sales and marketing capabilities on our own or through third parties, we will be unable to successfully commercialize our product candidate, if approved, or generate product revenue.

To commercialize our molgramostim product candidate, if approved, in the U.S. and other jurisdictions we seek to enter, we must build our marketing, sales, managerial, and other non-technical capabilities, or make arrangements with third parties to perform these services, and we may not be successful in doing so. If our product receives regulatory approval,

32

we expect to market such product in the U.S. through a focused, specialized sales force, which will be costly and time consuming. Institutionally, we have no prior experience in the marketing and sale of pharmaceutical products and there are significant risks involved in building and managing a sales organization, including our ability to hire, retain, and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel, and effectively manage a geographically dispersed sales and marketing team. Outside of the U.S., we may consider collaboration arrangements. If we are unable to enter into such arrangements on acceptable terms or at all, we may not be able to successfully commercialize our product in certain markets. Any failure or delay in the development of our internal sales, marketing, and distribution capabilities would adversely impact the commercialization of our product. If we are not successful in commercializing our molgramostim product, either on our own or through collaborations with one or more third parties, our future product revenue will suffer, and we would incur significant additional losses.

To establish a sales and marketing infrastructure and expand our manufacturing capabilities, we will need to increase the size of our organization, and we may experience difficulties in managing this growth.

As of March 30, 2022,7, 2024, we had 2237 employees including 1425 employees engaged in research and development. As we advance our molgramostim product candidate through the development process and to commercialization, we will need to continue to expand our development, regulatory, quality, managerial, sales and marketing, operational, finance, and other resources to manage our operations and clinical trials, continue our development activities, and commercialize our product candidate, if approved. As our operations expand, we expect that we will need to manage additional relationships with various manufacturers and collaborative partners, suppliers, and other organizations.

Due to our limited financial resources and our limited experience in managing a company with such anticipated growth, we may not be able to effectively maintain or manage the expansion of our operations or recruit and train additional qualified personnel. In addition, the physical expansion of our operations may lead to significant costs and may divert our management attention and resources. Any inability to manage growth could delay the execution of our development and strategic objectives, or disrupt our operations, which could materially impact our business, revenue, and operating results.

Risks Related to Information TechnologyOur Business Operations

Our operations might be interrupted and Data Privacyfinancial results could be adversely impacted by the occurrence of a natural disaster, acts of war or terrorism, IT system malfunction, telecommunication and electrical failures or other catastrophic event, or public health crises, such as a pandemic.

Our corporate headquarters is located in a commercial facility in Langhorne, Pennsylvania. Important documents and records, including copies of our regulatory documents and other records for our product candidate, are located both at a secure offsite document storage facility as well as at our own facilities, and we depend on our facilities for the continued operation of our business. Natural disasters and other catastrophic events, such as wildfires and other fires, earthquakes and extended power interruptions, public health crises, severe weather conditions, social unrest, such as that in Argentina, or acts of war or terrorism, such as the conflicts both in the Middle East and between Russia and Ukraine, could significantly disrupt our operations and result in additional, unplanned expense. Any natural disaster or catastrophic

event could disrupt our business operations and result in setbacks to our development programs. Even though we believe we carry commercially reasonable insurance, we might suffer losses that are not covered by or exceed the coverage available under these insurance policies.

In addition, our operations may be adversely impacted by international conflict, such as the ongoing conflicts in both the Middle East and Ukraine, or social unrest, such as that currently in Argentina. The political and physical conditions in those regions, as well as neighboring countries, may disrupt our supply chain and increase our costs, which may adversely affect our ability to conduct ongoing clinical trials and impact patients’ ability to partake in our clinical trials. While we do not believe these conflicts will have a material impact on our current operations, given the rapidly evolving situation, the full impact of the conflict remains uncertain.

Our business and operations would suffer in the event of third-party computer system failures, cyber-attacks on third-party systems, or deficiency in our cyber-security.cybersecurity.

We rely on information technology (“IT”)IT systems, including third-party “cloud based” service providers, to keep financial records, maintain laboratory data, clinical data and corporate records, communicate with staff and external parties, and operate other critical functions. This includes critical systems such as email, other communication tools, electronic document repositories, and archives. If any of these third-party IT providers are compromised due to computer viruses, unauthorized access, malware, natural disasters, fire, terrorism, war and telecommunication failures, electrical failures, cyber-attacks, or cyber-intrusions over the internet, then sensitive emails or documents could be exposed or deleted. Similarly, we could incur business disruption if our access to the internet is compromised, and we are unable to connect with third-party IT providers. The risk of a security breach or disruption, particularly through cyber-attacks or cyber-intrusion by computer hackers, foreign governments, or cyber-terrorists, has generally increased as the number, intensity, and sophistication of attempted attacks and intrusions from around the world have increased. In addition, we rely on those third parties to safeguard important confidential personal data regarding our employees and patients enrolled in our clinical trials. If a disruption event were to occur and cause interruptions in a third-party IT provider’s operations, it could result in a disruption of our drug development programs. For example, the loss of clinical trial data from completed, ongoing, or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach results in loss or damage to our data or applications or inappropriate disclosure of confidential or proprietary information, we could incur liability and development of our product candidate could be delayed or could fail.

We have experienced and may continue to experience attempts to breach our security and attempts to introduce malicious software into our IT systems; however, to date and to our knowledge, such attacks have not resulted in any material damage to us. Because of the frequently changing attack techniques, along with the increased volume and sophistication of the attacks, there is the potential for the Company to be adversely impacted. Moreover, because the techniques used to gain access to or sabotage systems often are not recognized until launched against a target, we may be unable to anticipate the methods necessary to defend against these types of attacks, and we cannot predict the extent, frequency or impact these attacks may have on us. To the extent our business is interrupted, this impact could result in reputational, competitive, operational, or other business harm as well as financial costs and regulatory action, and the theft or unauthorized use or publication of our trade secrets and other confidential business information as a result of such an incident could adversely affect our competitive position.

We are continually working to maintain reliable systems to improve our operations. Our efforts include, but are not limited to, the following: firewalls, antivirus protection, patches, log monitors, routine backups with offsite retention of storage media, system audits, data partitioning, and routine password modifications. Our internal IT systems environment continues to evolve, and our business policies and internal security controls may not keep pace as new threats emerge. No assurance can be given that our efforts to continue to enhance our systems will be successful.

The Company’s remote working arrangements could significantly increase the Company’s digital and cybersecurity risks.

A majority of our employees work remotely from their homes. With the shift to remote working and the use of virtual board and executive management meetings, cybersecurity risks are exponentially greater. Additionally, the Company’s adoption of remote work arrangements may introduce additional threats to our information technology networks and infrastructure. Technology in employees’ homes may not be as robust and could cause the networks, information systems, applications, and other tools available to employees to be more limited or less reliable than in our offices. These cyber risks include greater phishing, malware, and other cybersecurity attacks, vulnerability to disruptions of our information technology infrastructure and telecommunication systems for remote operations, increased risk of unauthorized dissemination of confidential information, limited ability to restore the systems in the event of a systems failure or interruption, greater risk of a security breach resulting in destruction or misuse of valuable information, and potential impairment of our ability to

perform critical functions, including wiring funds, all of which could expose us to risks of data or financial loss, litigation and liability and could seriously disrupt our operations.

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

A

We are subject to a number of state, national, and foreign laws and regulations applyrelated to the collection, use, retention, protection, disclosure, transfer, and other processing of personal data. Due to our Danish subsidiary, Savara ApS, our clinical trial activities, and operations in Europe, we are subject to data, protection laws in the EU, including the EU’s General Data Protection Regulation (“GDPR”). The scope of these laws can be broad, and the statutory penalties can be high. For example, the GDPR which became effective on May 25, 2018, has caused the EUimposes stringent requirements for the protectionprocessing of personal data to become more stringentof individuals within the EU and increased theprovides for substantial penalties for non-compliance. Penaltiesnon-compliance that can consist of finesbe up to the greater of €20 million or 4% of global annual revenues, whicheverrevenues.

The legal landscape in this area is higher. As a result, we have been requiredrapidly evolving as different jurisdictions adopt new laws governing data privacy, which can differ in scope and applicability, subject to implement additional mechanisms to ensure compliance with the new EU data protection rules, which may cause us to incur additional costs. Similarly, in Junedifferent interpretations, and be inconsistent among jurisdictions. In 2018, California enacted the California Consumer Privacy Act of 2018, (the “CCPA”), which became effective in January 2020.

The CCPA createsinformation and a private right of action for statutory damages for certain breachesbreaches. Since then, a number of information and the California Attorney General has proposed regulations under the CCPA which became effective on July 1, 2020. In addition, the California Privacy Rights Act was passed in November 2020 expanding CCPA regulations and will have an impact on our future privacy obligations.

In Canada, both the federal government and certain provinces have also proposed new legislation imposing significant and unprecedented obligations, fines, and liabilities regarding data handling. WeAs the applicable laws change, we may be required to implement additional mechanisms to comply, with the CCPA or such other state laws, or the proposed Canadian legislation, which may be difficult to implement and may require us to incur additional costs. If we or our vendors fail to comply with applicable data privacy laws, including the GDPR, we could be subject to government enforcement actions and significant penalties, against us, and our business could be adversely impacted. A data security breach or change in applicable privacy or security laws or regulations could require us to devote significant management resources to address the problems created by the breach or such change in laws or regulations, and, further, to expend significant additional resources to upgrade the security measures that we employ to guard against such breaches or comply with such change in laws or regulations, each of which could disrupt our business, operations, and financial condition. Because many of these laws are new, there is little clarity as to their interpretation, as well as a lack of precedent for the scope of enforcement.

Risks Related to Drug Development and Commercialization

We depend on the successful completion of clinical trials ofinformation, our molgramostim product candidate, and any positive results in prior clinical trials do not ensure that ongoing or future clinical trials will be successful.

Pharmaceutical products are subject to stringent regulatory requirements covering quality, safety, and efficacy. The burden of proof is on the manufacturer, such as us, to show with substantial clinical data that the risk/benefit profile for any new drug is favorable. Only after successfully completing extensive pharmaceutical development, nonclinical testing, and clinical trials may a product be considered for regulatory approval.

Clinical trials are expensive, difficult to design and implement, they can take many years to complete, and outcomes are inherently uncertain. A drug product may fail to demonstrate positive results at any stage of testing despite having progressed satisfactorily through nonclinical testing and initial clinical trials. There is significant risk in clinical development where later stage clinical trials are designed and powered based on the analysis of data from earlier trials, with these earlier trials involving a smaller number of patients, and the results of the earlier trials being driven primarily by a subset of responsive patients. In addition, interim results of a clinical trial do not necessarily predict final results. Further, clinical trial data frequently are susceptible to varying interpretations. Medical professionals and/or regulatory authorities may analyze or weigh trial data differently than the sponsor company, resulting in delay or failure to obtain marketing approval for a product candidate. Additionally, the possible lack of standardization across multiple investigative sites may induce variability in the results which can interfere with the evaluation of treatment effects.

If we license rights to develop our product candidate to independent third parties or otherwise permit third parties to evaluate our product candidate in clinical trials, such as an investigator-sponsored clinical trial, we may have limited control over those clinical trials. For example, we have provided molgramostim and placebo for an investigator-sponsored clinical trial by the University of Giessen in Germany that will assess the potential efficacy of molgramostim in preventing progression of COVID-19 pneumonia to acute respiratory distress syndrome. Any safety or efficacy concern identified in a third-party sponsored trial could adversely affect our or another licensee’s development of our product candidate and prospects for its regulatory approval, even if the data from that trial are subject to varying interpretations and analyses. If serious adverse events are observed in such third-party sponsored trials, it could delay or cause the discontinuation of the development of the product candidate and have a material adverse effect on our business.

There are significant risks that ongoing and future clinical trials of our product candidate will not be successful. Negative or inconclusive results could cause the FDA and other regulatory authorities to require us to repeat or conduct additional clinical trials, which could significantly increase the time and expense associated with development of that product candidate or cause us to elect to discontinue one or more clinical programs.

Molgramostim has received Orphan Drug Designation by the FDA and in Europe. If a competitor obtains Orphan Drug exclusivity for a product with the same active ingredient and route of delivery as molgramostim for aPAP, weefforts may be unable to market our product candidate until the exclusivity of the competing product expires.

Molgramostim has received Orphan Drug Designation in the U.S. by the FDAunsuccessful and in Europe by the EMA for the treatment of aPAP. Orphan Drug Designation will not shorten the regulatory review or reduce the clinical data requirements needed to obtain approval. If approval is received to market molgramostim, the FDA will not approve a similar product, with the same active ingredient, to molgramostim for seven years and the EMA will not approve a similar product to molgramostim for ten years, unless we are unable to produce enough supply to meet demand in the marketplace or another similar product, with the same active ingredient, is deemed clinically superior. Similar product candidates, with the same active ingredient and route of delivery, may be granted Orphan Drug Designation during the development of the respective products, but the Orphan Drug exclusivity is granted only to the first of such products approved, which means there is risk that a competitor product candidate may receive approval and Orphan Drug exclusivity before us, thus preventing us from marketing our product candidate until the exclusivity of the competing product expires. Also, the Orphan Drug status will not prevent a competitor with a different active ingredient from competing with our product candidate. If we are prevented from marketing one or more product candidate due to a competitor’s Orphan Drug exclusivity, this would have a material adverse effect on our business.

Delays in commencement and completion of clinical trials are common and have many causes. Delays in clinical trials of our molgramostim product candidate would likely increase overall development costs and jeopardize our ability to obtain regulatory approval and successfully commercialize any approved product.

Clinical development typically is expensive, can take many years to complete, and its outcome is inherently uncertain. Clinical trials may not commence on time or be completed on schedule, if at all. The commencement and completion of clinical trials can be delayed for a variety of reasons, including:

36

Patient enrollment, a critical component to successful completion of a clinical trial, is affected by many factors, including the size and nature of the trial population, the proximity of patients to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, ongoing trial competing for the same patient population and clinicians, and patients’ perceptions as to the potential advantages of the drug being studied in relation to available alternatives, including therapies being investigated by other companies which may be viewed as more beneficial or important to study, fear of being randomized to the placebo arm, and changes in standard of care. Challenges to complete enrollment can be exacerbated in orphan indications, like those being pursued by us, with a limited number of qualifying patients and the lack of clinical sites with the necessary expertise and experience to conduct our trials. Further, completion of a clinical trial and/or its results may be adversely affected by failure to retain patients who enroll in a trial but withdraw due to adverse side effects, perceived lack of efficacy, belief that they are on placebo, improvement in condition before treatment has been completed, for personal reasons, without reason, or by patients who fail to return for or complete post-treatment follow-up.

For example, although we are not aware of any companies developing an inhaled form of GM-CSF for the treatment of aPAP, Leukine® (sargramostim), a yeast-derived recombinant human granulocyte-macrophage colony stimulating factor, rhu-GM-CSF, which is a product of Partner Therapeutics, Inc., is being utilized by some patients, domestically and internationally, for the off-label treatment of aPAP. Additionally, Partner Therapeutics, Inc. is working with the Pharmaceuticals and Medical Devices Agency and the Ministry of Health, Labour, and Welfare in Japan for regulatory approval of Leukine® for the treatment of aPAP. We cannot assess the likelihood of formal regulatory approval of Leukine®, the effectiveness of its off-label administration to patients with aPAP, or the number of aPAP patients using Leukine® for off-label treatment. However, the current off-label administration of Leukine® could adversely affect the enrollment of patients in our IMPALA-2 trial.

Additionally, as we continue to advance the IMPALA-2 trial, there remains a general uncertainty regarding the impact of COVID-19 and emerging variants on the aPAP patient population and physicians. Patients suffering from aPAP are prone to underlying lung conditions and are often treated by infectious disease specialists and pulmonologists. These treating physicians are on the front lines in addressing this global pandemic and must now, understandably, focus their attention on COVID-19. Further, if an aPAP patient enrolled in the trial were to contract COVID-19, they may need to discontinue their participation.

Clinical trials may not begin on time or be completed in the time frames we anticipate and may be costlier than we anticipate for a variety of reasons, including one or more of those described above. The length of time necessary to successfully complete clinical trials vary significantly and is difficult to predict accurately. We may make statements regarding anticipated timing for completion of enrollment in and/or availability of results from our clinical trials, but such predictions are subject to a number of significant assumptions and actual timing may differ materially for a variety of reasons, including patient enrollment rates, length of time needed to prepare raw trial data for analysis and then to review and analyze it, and other factors described above. If we experience delays in the completion of a clinical trial, if a clinical trial is terminated, or if failure to conduct a trial in accordance with regulatory requirements or the trial’s protocol leads to deficient safety and/or efficacy data, the regulatory approval and/or commercial prospects for our product candidate may be harmed, and our ability to generate product revenue will be delayed. In addition, any delays in completing our clinical trials likely will increase our development costs. Further, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials have in the past and may in the future ultimately lead to the denial of regulatory approval of a product candidate. Even if we ultimately commercialize a product candidate, the standard of care may have changed or other therapies for the same indications may have been introduced to the market in the interim and may establish a competitive threat to us or diminish the need for our products.

Clinical trials are very expensive, difficult to design and implement, often take many years to complete, and the outcome is inherently uncertain.

Clinical development of pharmaceutical products for humans is generally very expensive, takes many years to complete, and failures can occur at any stage of clinical testing. We estimate that clinical development of our product candidate will take several additional years to complete; however, because of the variety of factors that can affect the design, timing, and outcome of clinical trials, we are unable to estimate the exact funds required to complete research and development, obtain regulatory approval, and commercialize our product candidate. We will need significant additional capital to continue to advance our products as per current business plans.

Failure at any stage of clinical testing is not uncommon and we may encounter problems that would require additional, unplanned trials or cause us to abandon a clinical development program.

37

In addition, a clinical trial may be suspended or terminated by us, an Independent Review Board (“IRB”), a data safety monitoring board, the FDA, or other regulatory authorities due to a number of factors, including:

Changes in governmental regulations and guidance relating to clinical trials may occur and we may need to amend clinical trial protocols to reflect these changes, or we may amend trial protocols for other reasons. Amendments may require us to resubmit protocols to IRBs for re-examination and approval or renegotiate terms with CROs, clinical trial sites, and investigators, all of which may adversely impact the costs or timing of or our ability to successfully complete a trial.

There is significant uncertainty regarding the regulatory approval process for any investigational new drug, substantial further testing and validation of our product candidate and related manufacturing processes may be required, and regulatory approval may be conditioned, delayed, or denied, any of which could delay or prevent us from successfully marketing our product candidate and substantially harm our business.

Pharmaceutical products generally are subject to rigorous nonclinical testing and clinical trials and other approval procedures mandated by the FDA and foreign regulatory authorities. Various federal and foreign statutes and regulations also govern or materially influence the manufacturing, safety, labeling, storage, record keeping, and marketing of pharmaceutical products. The process of obtaining these approvals and the subsequent compliance with appropriate U.S. and foreign statutes and regulations is time-consuming and requires the expenditure of substantial resources. Molgramostim is currently in Phase 3 clinical testing. The top line results from our first Phase 3 clinical trial, IMPALA, were released by us on June 12, 2019 and did not meet all of the statistical goals and protocol end points. On October 1, 2019, we received a written response from the FDA in connection with a Type C meeting regarding the molgramostim development program for aPAP and results from IMPALA in which the FDA indicated that the data provided in the briefing package for the Type C meeting did not provide sufficient evidence of efficacy and safety for the treatment of aPAP.

On December 23, 2019, the FDA provided communication to us regarding the granting of Breakthrough Therapy designation, a process designed to expedite the development and review of drugs that are intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on clinically significant endpoint(s), for molgramostim for the treatment of aPAP. As such, we have worked with the FDA and EMA and determined the scope and design of an additional Phase 3 trial for the molgramostim development program for the treatment of aPAP, the IMPALA-2 trial. The scope, powering, cost, and timing of IMPALA-2 will require us to expend substantial additional resources. Additional clinical trials, and/or other costly trials, could require us to expend substantial additional resources and could significantly extend the timeline for clinical development prior to market approval.

Significant uncertainty exists with respect to the regulatory approval process for any investigational new drug, including molgramostim. Regardless of any guidance the FDA or foreign regulatory agencies may provide a drug’s sponsor during its development, the FDA or foreign regulatory agencies retain complete discretion in deciding whether to accept a BLA, or the equivalent foreign regulatory approval submission for filing or, if accepted, whether to approve a BLA. There are many components to a BLA or marketing authorization application submission in addition to clinical trial data. For example, the FDA or foreign regulatory agencies will review the sponsor’s internal systems and processes, as well as those of its CROs, CMOs, and other vendors, related to development of its product candidates, including those pertaining to its clinical studies and manufacturing processes. Before accepting a BLA or the equivalent foreign regulatory approval submission for review or before approving the BLA or its equivalent, the FDA or foreign regulatory agencies may request that we provide additional information that may require significant resources and time to generate and there is no guarantee that our product candidate will be approved for any indication for which we may apply. The FDA or foreign regulatory agencies may choose not to approve a BLA or its equivalent for a variety of reasons, including a decision related to the safety or efficacy data, manufacturing controls or systems, or for any other issues that the agency may identify related to the development of its product candidates. Even if one or more Phase 3 clinical trials are successful in providing statistically significant evidence of the efficacy and safety of the investigational drug, the FDA or foreign regulatory agencies may not consider efficacy and safety data from the submitted trials adequate scientific support for a conclusion of effectiveness and/or safety and may require one or more additional Phase 3 or other trials prior to granting marketing approval. If this were to occur, the overall development cost for the product candidate would be substantially

38

greater and competitors may bring products to market before us, which could impair our ability to generate revenues from the product candidate, or even seek approval, if blocked by a competitor’s Orphan Drug exclusivity, which would have a material adverse effect on our business, financial condition, and results of operations.

Further, development of our product candidate and/or regulatory approval may be delayed for reasons beyond our control. For example, U.S. federal government shut-downs or budget sequestrations, such as ones that occurred during January 2018 and December 2018 through January 2019, may result in significant reductions to the FDA’s budget, employees, and operations, which may lead to slower response times and longer review periods, potentially affecting our ability to progress development of our product candidate or obtain regulatory approval for our product candidate. Further, regulatory oversight and actions may be disrupted or delayed in regions particularly impacted by COVID-19 and emerging variants if regulators and industry professionals are expending significant and unexpected resources addressing the outbreak.

Even if the FDA or foreign regulatory agencies grant approvals for a product candidate, the conditions or scope of the approval(s) may limit successful commercialization of the product candidate and impair our ability to generate substantial sales revenue. For example, molgramostim could be approved with restrictions for use only by patients unresponsive to the current standard of care or the FDA may approve label claims with age restrictions and/or treatment duration limitations. They may limit the label of molgramostim to a subset of patients based on a review of which patient groups had the greatest efficacious response in clinical trials. Such label restriction may be undesirable and may limit successful commercialization. The FDA or foreign regulatory agencies may also only grant marketing approval contingent on the performance of costly post-approval nonclinical or clinical studies, or subject to warnings or contraindications that limit commercialization. Additionally, even after granting approval, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, and recordkeeping for our products will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, and continued compliance with cGMP, GCP, international conference on harmonization regulations, and GLP, which are regulations and guidelines that are enforced by the FDA or foreign regulatory agencies for all clinical development and for any clinical studies that we conduct post-approval. The FDA or foreign regulatory agencies may decide to withdraw approval, add warnings, or narrow the approved indications in the product label, or establish risk management programs that could restrict distribution of our products. These actions could result from, among other things, safety concerns, including unexpected side effects or drug interaction problems, or concerns over misuse of a product. If any of these actions were to occur following approval, we may have to discontinue commercialization of the product, limit our sales and marketing efforts, implement risk minimization procedures, and/or conduct post-approval studies, which in turn could result in significant expense and delay or limit our ability to generate sales revenues.

Regulations may be changed prior to submission of a marketing application that require higher hurdles than currently anticipated. These may occur as a result of drug scandals, recalls, or a political environment unrelated to our products.

Even if we receive regulatory approval for our primary product candidate, we may face regulatory difficulties that could materially and adversely affect our business, financial condition, and results of operations.

Even if initial regulatory approval is obtained, as a condition to the initial approval, the FDA or a foreign regulatory agency may impose significant restrictions on a product’s indicated uses or marketing or impose ongoing requirements for potentially costly post-approval studies or marketing surveillance programs, any of which would limit the commercial potential of the product. Our molgramostim product candidate also will be subject to ongoing FDA requirements related to the manufacturing processes, labeling, packaging, storage, distribution, advertising, promotion, record-keeping, and submission of safety and other post-market information regarding the product. For instance, the FDA may require changes to approved drug labels, require post-approval clinical studies, and impose distribution and use restrictions on certain drug products. In addition, approved products, manufacturers, and manufacturers’ facilities are subject to continuing regulatory review and periodic inspections. If previously unknown problems with a product are discovered, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, the FDA may impose restrictions on that product or us, including requiring withdrawal of the product from the market. If we or a CMO of ours fail to comply with applicable regulatory requirements, a regulatory agency may:

39

If our product candidate receives regulatory approval but fails to achieve significant market acceptance among the medical community, patients, or third-party payers, the revenue we generate from its sales will be limited and our business may never achieve profitability.

Our success will depend in substantial part on the extent to which our product candidate, if approved, is accepted by the medical community and patients and reimbursed by third-party payers, including government payers. The degree of market acceptance with respect to our approved product, if any, will depend upon a number of factors, including:

We cannot predict with reasonable accuracy whether physicians, patients, healthcare insurers, health maintenance organizations, or the medical community in general, will accept or utilize our product, if approved. If our product candidate is approved but does not achieve an adequate level of acceptance by these parties, we may not generate sufficient revenue to become or remain profitable. In addition, our efforts to educate the medical community and third-party payers regarding benefits of our product may require significant resources and may never be successful.

If we determine that a product candidate may not achieve adequate market acceptance or that the potential market size does not justify additional expenditures on the program, we may reduce our expenditures on the development and/or the process of seeking regulatory approval of the product candidate while we evaluate whether and on what timeline to move the program forward.

Even if we receive regulatory approval to market our product candidate in the U.S., we may never receive approval or commercialize our product outside of the U.S., which would limit our ability to realize the full commercial potential of our product candidate.

In order to market products outside of the U.S., we must establish and comply with the numerous and varying regulatory requirements of other countries regarding safety and efficacy. Approval procedures vary among countries and can involve additional product testing and validation and additional administrative review periods. The time required to obtain approval in other countries generally differs from that required to obtain FDA approval. The regulatory approval process in other countries may include all of the risks detailed above regarding FDA approval in the U.S., as well as other risks. Regulatory

40

approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in others. Failure to obtain regulatory approval in other countries or any delay or setback in obtaining such approval could have the same adverse effects detailed above regarding FDA approval in the U.S. As described above, such effects include the risks that our product candidate may not be approved for all indications requested, which could limit the uses of our product candidate and have an adverse effect on product sales, and that such approval may be subject to limitations on the indicated uses for which the product may be marketed or require costly, post-marketing follow-up trials. Conversely, if the product candidate does receive approval outside the U.S. in the future, we may not meet the FDA requirements in the U.S. for approval.costs.

We must comply with the U.S. Foreign Corrupt Practices Act and similar foreign anti-corruption laws.

The FCPA, to which weWe are subject prohibits corporationsto anti-corruption laws, including the FCPA, the U.K. Bribery Act 2010, and individuals from engagingother anti-corruption laws that apply in certain activities to obtain or retain business or to influence a person working in an official capacity. Itcountries where we conduct business. Under those laws, it is generally illegal to pay, offer to pay, or authorize the payment of anything of value to any foreign government official, government staff member, political party, or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official capacity.

We face the risk that an employee or agent could be accused of violating one or more of these laws, particularly in geographies where significant overlap exists between local government and healthcare industries. In many countries, hospitals are operated by the government and doctors and other hospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed to be improper payments to government officials and have led to FCPA enforcement actions. Such an accusation, even if unwarranted, could prove disruptive to our developmental and commercialization efforts. The FCPA also obligates companies whose securities are listed in the U.S. to comply with certain accounting provisions, requiringand the company to maintain books and records that accurately and fairly reflect all transactions of the company, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations. The SEC may suspend or bar issuers from trading securities on U.S. exchanges for violations of the FCPA’s accountingthose provisions.

Other countries haveOur operations also subject us to similar laws with which we must comply.in other countries. The provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order, or use of medicinal products is prohibited in the E.U. The, and the provision of benefits or advantages to physicians is also governed by the national anti-bribery laws, such as the U.K. Bribery Act 2010.laws. Infringement of these laws could result in substantial fines and imprisonment. Payments made to physicians in certain E.U. member states must be publicly disclosed. Moreover, agreements with physicians often must be the subject of prior notification and approval by the physician’s employer, his or her competent professional organization and/or the regulatory authorities of the individual country. These requirements are provided in the national laws, industry codes, or professional codes of conduct. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines, or imprisonment.

Risks Related to Our Intellectual Property

Our success will depend on obtaining and maintaining effectiveIf we are unable to adequately protect our intellectual property protection forrights related to our product candidate, and proprietary technology.it could have a material adverse effect on our business.

We have no patent protectionissued patents for molgramostim for the treatment of aPAP and primarily rely on the Orphan Drug exclusivity as our primary barrier to competition. Molgramostim utilizesAdditionally, we have an exclusive supply agreement for the proprietary delivery devices with exclusive supply agreementsdevice used for molgramostim and receives additional protection via a proprietary cell bank used in the production of the drug substance.

Our success will depend on our ability to:

41

The patent and intellectual property positions of biopharmaceutical companies generally are highly uncertain, involve complex legal and factual questions, and have been and continue to be the subject of much litigation. There is no guarantee that we have or will develop or obtain the rights to products or processes that are patentable, that patents will issue from any pending applications or that claims allowed will be sufficient to protect the technology we develop or have developed or that is used by us, our CMOs, or our other service providers. In addition, any patents that are issued to us may be limited in scope or challenged, invalidated, infringed, or circumvented, including by our competitors, and rights we have under issued patents may not provide competitive advantages to us. If competitors can develop and commercialize technology and products similar to ours, our ability to successfully commercialize our technology and products may be impaired.

Patent applications in the U.S. are confidential for a period of time until they are published, and publication of discoveries in scientific or patent literature typically lags actual discoveries by several months. As a result, we cannot be certain that the inventors listed in any patent or patent application owned by us were the first to conceive of the inventions covered by such patents and patent applications (for U.S. patent applications filed before March 15, 2013), or that such inventors were the first to file patent applications for such inventions outside the U.S. and, after March 15, 2013, in the U.S. In addition, changes in or different interpretations of patent laws in the U.S. and foreign countries may affect our patent rights and limit the number of patents we can obtain, which could permit others to use our discoveries or to develop and commercialize our technology and products without any compensation to us.

We also rely on unpatented know-how and trade secrets and continuing technological innovation to develop and maintain our competitive position, which we seek to protect, in part, through confidentiality agreements with employees, consultants, collaborators, and others. We also have invention or patent assignment agreements with our employees and certain consultants. The steps we have taken to protect our proprietary rights, however, may not be adequate to preclude misappropriation of or otherwise protect our proprietary information or prevent infringement of our intellectual property rights, and we may not have adequate remedies for any such misappropriation or infringement. In addition, it is possible that inventions relevant to our business could be developed by a person not bound by an invention assignment agreement with us or independently discovered by a competitor.

We also intend to rely on regulatory exclusivity for protection of our molgramostim product candidate, if approved for commercial sale. Implementation and enforcement of regulatory exclusivity, which may consist of regulatory data protection and market protection, varies widely from country to country. Failure to qualify for regulatory exclusivity, or failure to obtain or maintain the extent or duration of such protections that we expect for our product candidate, if approved, could affect our decision on whether to market the products in a particular country or countries or could otherwise have an adverse impact on our revenue or results of operations. For molgramostim, which is administered via nebulization, we may rely on regulatory exclusivity for the combination of molgramostim and its delivery system. However, there is no assurance that our molgramostim product and its delivery system, if approved, will benefit from this type of market protection.

We have filed patent applications related to our molgramostim product candidate; however, there is no guarantee that patents will issue from any pending or future applications or that claims allowed will be sufficient to protect the technology we develop or that is used by us, our CMOs, or our other service providers. The patent prosecution process is expensive and time-consuming; we may not be able to file or prosecute patents on certain aspects of our product candidate at a reasonable cost, in a timely fashion, or at all, and we may fail to identify patentable aspects of inventions made during development activities before it is too late to obtain patent protection. Further, defects of form in the preparation or filing of our patent applications may exist, or may arise in the future, which may cause them to be invalid or unenforceable.

Any patents that are issued to us may be limited in scope or challenged, invalidated, infringed, or circumvented, including by our competitors. Even if a patent issues and is held valid and enforceable, rights we have under the patent may not provide a competitive advantage to us. Competitors may be able to design around our patents, such as by using pre-existing or newly developed technology. Additionally, given the amount of time required for the development, testing, and regulatory review of new drug candidates, patents protecting such candidates might expire shortly after such candidates are commercialized. If competitors can develop and commercialize technology and products similar to ours, our ability to successfully commercialize our technology and products may be impaired.

We also rely on unpatented know-how and trade secrets and continuing technological innovation to develop and maintain our competitive position, which we seek to protect, in part, through confidentiality agreements with employees, consultants, collaborators, and others. We also have invention or patent assignment agreements with our employees and certain consultants. The steps we have taken to protect our proprietary rights, however, may not be adequate to preclude misappropriation of or otherwise protect our proprietary information or prevent infringement of our intellectual property rights, and we may not have adequate remedies for any such misappropriation or infringement. In addition, it is possible that inventions relevant to our business could be developed by a person not bound by an invention assignment agreement with us or independently discovered by a competitor.

We may rely on trademarks, trade names, and brand names to distinguish our molgramostim product, if approved for commercial sale, from the products of our competitors. We intend to seek approval for a new name for molgramostim that meets the FDA’s and foreign regulatory requirements. However, our trademark applications may not be approved. Third parties may also oppose our trademark applications or otherwise challenge our use of the trademarks, in which case we may expend substantial resources to defend our proposed or approved trademarks and may enter into agreements with third parties that may limit our use of our trademarks. In the event thatIf our trademarks are successfully challenged, we could be forced to rebrand our product, which could result in loss of brand recognition and could require us to devote significant resources to advertising and marketing these new brands. For example, we filed a trademark for the name “Savara” and were

challenged. We decided to terminate the application, but we may revisit such filings at a future date. Further, our competitors may infringe on our trademarks, or we may not have adequate resources to enforce our trademarks.

Our success depends on our ability to prevent competitors from duplicating or developing and commercializing equivalent versions of our product candidate, but patent protection may be difficult to obtain and any issued claims may be limited.

If we are issued a patent, itWe may not provide us with significant competitive advantages because the validity or enforceability of the patents may be challenged and, if instituted, one or more of the challenges may be successful. Patents may be challenged in the U.S. under post-grant review proceedings, inter partes re-examination, ex parte re-examination, or challenges in district court. Patents issued in foreign jurisdictions may be subjected to comparable proceedings lodged in various foreign patent offices, or courts. These proceedings could result in either loss of the patent or loss or reduction in the scope of one or more of the claims of the patent. Even if a patent issues and is held valid and enforceable, competitors may be able to design aroundenforce our patents, such as by using pre-existing or newly developed technology, in which case competitors may not infringe our issued claims and may be able to market and sell products that compete directly with us before and after our patents expire.

The patent prosecution process is expensive and time-consuming. We and any future licensors and licensees may not apply for or prosecute patents on certain aspects of our product candidate at a reasonable cost, in a timely fashion, or at

42

all. We may not have the right to control the preparation, filing, and prosecution of some patent applications related to our product candidate or technology. As a result, these patents and patent applications may not be prosecuted and enforced in a manner consistent with our best interests. It is also possible that we or any future 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. Further, it is possible that defects of form in the preparation or filing of our patent applications may exist, or may arise in the future, such as with respect to proper priority claims, inventorship, assignment, or claim scope. 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. In addition, one or more parties may independently develop similar technologies or methods, duplicate our technologies or methods, or design around the patented aspects of our products, technologies, or methods. Any of these circumstances could impair our ability to protect our products, if approved, in ways which may have an adverse impact on our business, financial condition, and operating results.

Furthermore, the issuance of a patent is not conclusive as to its inventorship, scope, validity, or enforceability, and future patents we may own or license may be challenged in the courts or patent offices in andintellectual property rights outside of the U.S. 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 use our patents to stop others from using or commercializing similar or identical products or technology, or limit the duration of the patent protection of our technology and drugs. Given the amount of time required for the development, testing, and regulatory review of new drug candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized.

Enforcement of intellectual property rights in certain countries outside the U.S. has been limited or non-existent. Future enforcement of patents and proprietary rights in many other countries will likely be problematic or unpredictable. Moreover, the issuance of a patent in one country does not assure the issuance of a similar patent in another country. Claim interpretation and infringement laws vary by nation, so the extent of any patent protection is uncertain and may vary in different jurisdictions.jurisdictions, which could permit others to use our discoveries or to develop and commercialize our technology and products without any compensation to us.

Obtaining and maintaining 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 United States Patent and Trademark Office (“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 been issued. There are situations in which non-compliance can result in decreased patent term adjustment or in abandonment or lapse of the patent or patent application, leading to partial or complete loss of patent rights in the relevant jurisdiction.

Third parties may claim that our product, if approved, infringes on their proprietary rights and may challenge the approved use or uses of a product or its patent rights through litigation or administrative proceedings, and defending such actions may be costly and time consuming, divert management attention away from our business, and result in an unfavorable outcome that could have an adverse effect on our business.

Our commercial success depends on our ability and the ability of our CMOs and component suppliers to develop, manufacture, market, and sell our product and product candidate and use our proprietary technology without infringing the proprietary rights of third parties. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are or may be developing products. Because patent applications can take many years to publish and issue, there currently may be pending applications, unknown to us, that may later result in issued patents that our product, product candidate or technology infringe, or that the process of manufacturing our product or any of our respective component materials, or the component materials themselves, infringe, or that the use of our product product candidate or technology infringe.

We or our CMOs or component material suppliers may be exposed to, or threatened with, litigation by a third party alleging that our product product candidate and/or technology infringe its patents and/or other intellectual property rights, or that one or more of the processes for manufacturing our product or any of our respective component materials, or the component materials themselves, or the use of our product product candidate or technology, infringe its patents and/or other intellectual property rights. If a third-party patent or other intellectual property right is found to cover our product, product candidate, technology, or our uses, or any of the underlying manufacturing processes or components, we could be required to pay damages and could be unable to commercialize our product or use our technology or method unless we are able to obtain a license to the patent or intellectual property right. A license may not be available to us in a timely manner or on acceptable terms, or at all. In addition, during litigation, the third-party alleging infringement could obtain a preliminary injunction or other equitable remedy that could prohibit us from making, using, selling, or importing our product, technology, or method.

43

There generally is a substantial amount of litigation involving patent and other intellectual property rights in the industries in which we operate, and the cost of such litigation may be considerable. We can provide no assurance that our product candidate or technology will not infringe patents or rights owned by others, licenses to which might not be available to us in a timely manner or on acceptable terms, or at all. If a third partythird-party claims that we or our CMOs or component material suppliers infringe its intellectual property rights, we may face a number of issues, including, but not limited to:

There may be issued or filed claims covering our product, product candidate, or technology or those of our CMOs or component material suppliers or the use of our product, product candidate, or technology. Additionally, such patents may be issued or filed in the future. Because of the large number of patents issued and patent applications filed in the industries in which we operate, there is a risk that third parties may allege they have patent rights encompassing our product, product candidate, or technology, or those of our CMOs or component material suppliers, or uses of our product, product candidate, or technology.

In the future, it may be necessary for us to enforce our proprietary rights, or to determine the scope, validity, and unenforceability of other parties’ proprietary rights, through litigation or other dispute proceedings, which may be costly, and to the extent we are unsuccessful, adversely affect our rights. In these proceedings, a court or administrative body could determine that our claims, including those related to enforcing patent rights, are not valid or that an alleged infringer has not infringed our rights. The uncertainty resulting from the mere institution and continuation of any patent or other proprietary rights-related litigation or interference proceeding could have a material and adverse effect on our business prospects, operating results, and financial condition.

Risks Related to Our Industry

We expect competition in the marketplace for our molgramostim product candidate should it receive regulatory approval.

Molgramostim has received Orphan Drug Designation from the FDA and the EMA. Orphan Drug Designation will provide market exclusivity in the U.S. for seven years and ten years in Europe, but only if (i) molgramostim receives market approval before a competitor using the same active compound for the same indication, (ii) we are able to produce sufficient supply to meet demand in the marketplace, and (iii) another product with the same active ingredient is not deemed clinically superior.

The industries in which we operate (biopharmaceutical, specialty pharmaceutical, biotechnology, and pharmaceutical) are highly competitive and subject to rapid and significant change. Developments by others may render potential application of our molgramostim product candidate in a particular indication obsolete or noncompetitive, even prior to completion of its development and approval for that indication. If successfully developed and approved, we expect our product candidate will face competition. We may not be able to compete successfully against organizations with competitive products, particularly large pharmaceutical companies. Many of our potential competitors have significantly greater financial, technical, and human resources than us, and may be better equipped to develop, manufacture, market, and distribute products. Many of these companies operate large, well-funded research, development, and commercialization programs, have extensive experience in nonclinical and clinical trials, obtaining FDA and other regulatory approvals and manufacturing and marketing products, and have multiple products that have been approved or are in late-stage development. These advantages may enable them to receive approval from the FDA or any foreign regulatory agency before us and prevent us from competing due to their orphan drug protections. Smaller companies may also prove to be significant competitors, particularly through collaborative arrangements with large pharmaceutical and biotechnology companies. Furthermore, heightened awareness on the part of academic institutions, government agencies, and other public and private research organizations of the potential commercial value of their inventions have led them to actively

44

seek to commercialize the technologies they develop, which increases competition for investment in our programs. Competitive products may be more effective, easier to dose, or more effectively marketed and sold than ours, which would have a material adverse effect on our ability to generate revenue.

We are subject to uncertainty relating to healthcare reform measures and reimbursement policies that, if not favorable to our product, could hinder or prevent our product’s commercial success, if our product candidate is approved.

The unavailability or inadequacy of third-party payer coverage and reimbursement could negatively affect the market acceptance of our product candidate and the future revenues we may expect to receive from those products.receive. The commercial success of our product candidate, if approved, will depend on the extent to which the costs of such productsproduct will be covered by third-party payers, such as government health programs, commercial insurance, and other organizations. Third-party payers are increasingly challenging the prices and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. These challenges to prices may be problematic to us since our products are targeted for a small number of patients (those suffering from an orphan diseases)disease), thus requiring us to charge very high prices in order to recover development costs and achieve a profit on our revenue. If these third-party payers do not consider our productsproduct to be cost-effective compared to other therapies, we may not obtain coverage for our productsproduct after approval as a benefit under the third-party payers’ plans or, even if we do, the level of coverage or payment may not be sufficient to allow us to sell our productsproduct on a profitable basis.

Significant uncertainty exists as to the reimbursement status for newly approved drug products, including coding, coverage, and payment. There is no uniform policy requirement for coverage and reimbursement for drug products among third-party payers in the U.S., therefore coverage and reimbursement for drug products can differ significantly from payer to payer. The coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our productsproduct to each payer separately, with no assurance that coverage and adequate payment will be applied consistently or obtained. The process for determining whether a payer will cover and how much it will reimburse a product may be separate from the process of seeking approval of the product or for setting the price of the product. Even if reimbursement is provided, market acceptance of our productsproduct may be adversely affected if the amount of payment for our productsproduct proves to be unprofitable for healthcare providers or less profitable than alternative treatments or if administrative burdens make our productsproduct less desirable to use. Third-party payer reimbursement to providers of our products,product, if approved, may be subject to a bundled payment that also includes the procedure of administering our productsproduct or third-party payers may require providers to perform additional patient testing to justify the use of our products.product. To the extent there is no separate payment for our product(s),product, there may be further uncertainty as to the adequacy of reimbursement amounts.

The continuing efforts of governments, private insurance companies, and other organizations to contain or reduce costs of healthcare may adversely affect:

Our ability to successfully commercialize our productsproduct will depend on the extent to which governmental authorities, private health insurers, and other organizations establish what we believe are appropriate coverage and reimbursement for our products.product. The containment of healthcare costs has become a priority of federal and state governments worldwide and the prices of drug products have been a focus in this effort. For example, there have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs, and former President Trump signed four executive orders on July 24, 2020 aimed at bringing down pharmaceutical prices. We expect that federal, state, and local governments in the U.S., as well as in other countries, will continue to consider legislation directed at lowering the total cost of healthcare. In addition, in certain foreign markets, the pricing of drug products is subject to government control and reimbursement may in some cases be

unavailable or insufficient. It is uncertain whether and how future legislation, whether domestic or abroad, could affect prospects for our product candidate or what actions federal, state, or private payers for healthcare treatment and services may take in response to any such healthcare reform proposals or legislation. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures may

45

prevent or limit our ability to generate revenue, attain profitability, or commercialize our product candidate, especially in light of our plans to price our product candidate at a high level.

Furthermore, we expect that healthcare reform measures that may be adopted in the future are unpredictable, and the potential impact on our operations and financial position is uncertain, but may result in more rigorous coverage criteria, lower reimbursement, and additional downward pressure on the price we may receive for approved products. Any reduction in reimbursement from Medicare or other government-funded programs may result in a similar reduction in payments from private payers. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products, if approved.

We face potential product liability exposure and, if successful claims are brought against us, we may incur substantial liability for a product or product candidate and may have to limit its commercialization. In the future, we anticipate that we will need to obtain additional or increased product liability insurance coverage and it is uncertain whether such increased or additional insurance coverage can be obtained on commercially reasonable terms, if at all.

Our business (in particular, the use of our product candidate in clinical trials and the sale of any products for which we obtain marketing approval) will expose us to product liability risks. Product liability claims might be brought against us by patients, healthcare providers, pharmaceutical companies, or others selling or involved in the use of our products. If we cannot successfully defend ourselves against any such claims, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

We maintain limited product liability insurance for our clinical studies, but our insurance coverage may not reimburse us or may not be sufficient to reimburse us for all expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive and, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses.

We expect that we will expand our insurance coverage to include the sale of commercial products if we obtain marketing approval for our product candidate, but we may be unable to obtain product liability insurance on commercially acceptable terms or may not be able to maintain such insurance at a reasonable cost or in sufficient amounts to protect us against potential losses. Large judgments have been awarded in class action lawsuits based on drug products that had unanticipated side effects. A successful product liability claim or series of claims brought against us, if judgments exceed our insurance coverage, could consume a significant portion of our cash and adversely affect our business.

Risks Related to our Common Stock

Our stock price is expected to continue to be volatile.

The market price of our common stock has experienced substantial declinesvolatility since we announced the top-line results of our IMPALA Phase 2/3 trial of molgramostim for aPAP on June 12, 2019, and our stock price has been and is expected towill continue to be subject to significant volatility and fluctuations. Market prices for securities of early-stage pharmaceutical, biotechnology, and other life sciences companies have historically been particularly volatile. Some of the factors that may cause the market price of our common stock to fluctuate include:

46

Moreover, the stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of individual companies. Additionally, financial markets and the global economy may be adversely affected by the current or anticipated impact of the ongoing military conflict between Russiaconflicts in the Middle East and Ukraine or other related geopolitical events. These broad market fluctuations may also adversely affect the trading price of our common stock.

In the past, following periods of volatility in the market price of a company’s securities, such as the decline in our stock price, stockholders have often instituted class action securities litigation against those companies. Such litigation, if instituted, could result in substantial costs and diversion of management attention and resources, which could significantly harm our profitability and reputation.

If we fail to satisfy all applicable Nasdaq continued listing requirements, including the $1.00 minimum closing bid price requirement, our common stock may be delisted from Nasdaq, which could have an adverse impact on the liquidity and market price of our common stock.

Our common stock is currently listed on the Nasdaq Global Select Market, which has qualitative and quantitative continued listing requirements, including corporate governance requirements, public float requirements, and a $1.00

minimum closing bid price requirement. If our common stock trades at closing bid prices below $1.00 for 30 consecutive business days, or if we are unable to satisfy any of the other continued listing requirements, Nasdaq may take steps to delist our common stock. Such a delisting would likely have an adverse effect on the market liquidity of our common stock, decrease the market price of our common stock, result in the potential loss of confidence by investors, suppliers, customers, and employees, fewer business development opportunities, and adversely affect our ability to obtain financing for the continuation of our operations.

For example, on November 15, 2019, we received written notice from The Nasdaq Stock Market LLC indicating that, for the last 30 consecutive business days, the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued listing on the Nasdaq Global Select Market under Nasdaq Listing Rule 5550(a)(2). However, on December 10, 2019, we received written notice from The Nasdaq Stock Market LLC stating that because our shares had a closing bid price at or above $1.00 per share for a minimum of ten consecutive business days, our stock had regained compliance with the minimum bid price requirement of $1.00 per share for continued listing on the Nasdaq Global Select Market, as set forth in Nasdaq Listing Rule 5450(a)(1).

We will continue to incur costs and demands upon management as a result of complying with the laws and regulations affecting public companies.

As a public company, we will continue to incur significant legal, accounting and other expenses, including costs associated with public company reporting requirements. We will also continue to incur costs associated with corporate governance requirements, including requirements under the Sarbanes-Oxley Act, as well as rules implemented by the U.S. Securities and Exchange Commission (“SEC”) and Nasdaq. These rules and regulations may also make it difficult and expensive for us to obtain directors’ and officers’ liability insurance. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as executive officers, which may adversely affect investor confidence in us and cause our business or stock price to suffer.

In March 2020, the SEC amended the definitions of accelerated filer and large accelerated filer to exclude smaller reporting companies that have not yet begun to generate significant revenue. Accordingly, we changed our status from a smaller reporting company, accelerated filer, to a smaller reporting company, non-accelerated filer, effective for the 2020 annual report on Form 10-K. In accordance with the SEC amendments, we no longer require an integrated independent audit of our internal controls under Sarbanes-Oxley 404(b) but will continue to comply with Sarbanes-Oxley 404(a) and (c).

We do not expect to pay any cash dividends in the foreseeable future.

We expect to retain any future earnings to fund the development and growth of our business and do not expect to pay any cash dividends. As a result, capital appreciation, if any, of our common stock will be stockholders’ sole source of gain, if any, for the foreseeable future.

We may be unable to use certain of our net operating losses and other tax assets.

We have substantial tax loss carry forwards for USU.S. federal income tax and state income tax purposes. In general, our net operating losses and tax credits have been fully offset by a valuation allowance due to uncertainties surrounding our ability to realize these tax benefits. In particular, our ability to fully use certain USU.S. tax loss carry forwards and general business tax credit carry forwards generated up to and including December 20192023 to offset future income or tax liability is limited under section 382 of the Internal Revenue Code of 1986, as amended. Changes in the ownership of our stock, including those resulting from the issuance of shares of our common stock offerings or upon exercise of outstanding options, may limit or eliminate our ability to use certain net operating losses and tax credit carry forwards in the future.

Item 1B. Unresolved Staff Comments.

We do not have any unresolved comments issued by the SEC staff.

Item 1C. Cybersecurity.

Cyber Risk Management and Strategy

As part of our enterprise risk management program, we have implemented and maintain policies and processes to identify and mitigate risks posed by cybersecurity threats. Our policies and processes are based upon the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework, and we utilize technologies to help identify and manage potential cyber threats. We have also secured cyber-specific insurance coverage as part of our overall insurance portfolio.

We have engaged an independent, third-party services provider to assist in monitoring our information technology systems, as well as identifying, assessing, and mitigating the associated cyber risk. With that provider, we conduct periodic assessments of our information security program to evaluate the effectiveness of applicable security controls, which include penetration testing, vulnerability scanning, and red teaming. Our Chief Financial and Administrative Officer (“CF&AO”) reviews the results of those assessments with our third-party provider to reasonably address any identified potential gaps. We also utilize a range of tools and services to help ensure material threats are prevented or the risks of such threats are mitigated, which include, network and endpoint monitoring, system patching, user and server backups, annual awareness training, and periodic vulnerability evaluation. Management reviews monthly monitoring reports and meets with our third-party provider on a regular basis to review activities and debrief on any key IT-related issues.

We have an employee education program that includes annual training designed to raise awareness of cybersecurity threats, and we require employees to review and acknowledge our IT Security Policy on an annual basis. Additionally, we have adopted an IT Incident Response Plan that outlines the procedures to be followed in response to a data breach, whether internal or through a third-party, that are designed to help contain, assess, and respond to the incident and mitigate potential harm.

Our systems periodically experience directed attacks intended to lead to interruptions and delays in our operations as well as loss, misuse, or theft of information and other data, confidential information, or intellectual property. However, to date, these incidents have not had a material impact on our operations. Any significant disruption to our service or access to our systems could adversely affect our business and results of operation. Further, a penetration of our systems or a third-party’s systems or other misappropriation or misuse of information could subject us to business, regulatory, litigation, and reputation risk, which could have a negative effect on our business, financial condition and results of operations. See Risk Factors – Risks Related to Information Technology and Data Privacy.

Governance Related to Cybersecurity Risks

The Audit Committee of our Board of Directors is responsible for the general oversight of risks related to data privacy and cybersecurity. The Audit Committee periodically reviews the Company’s cybersecurity program with management, including (i) the adequacy of controls and security for the Company’s information technology systems and (ii) the Company’s response plan in the event of a security breach impacting those systems. Our CF&AO has primary responsibility for overseeing the day-to-day management of cybersecurity risks and has served in that role for three years. Our CF&AO oversees the policies and processes described above and provides the periodic management briefings to the Audit Committee, including any cybersecurity incidents and related responses. Further, at least annually, the Board of Directors receives updates of potential cybersecurity incidents, as well as the data privacy and compliance programs, and its members actively participate in discussions with management regarding cybersecurity risks.

Item 3. Legal Proceedings.

From time to time, we may become involved in various claims and legal proceedings. Regardless of outcome, litigation and other legal and administrative proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. We are not currently a party to any material pending litigation or other material legal proceeding.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the consolidated financial statements and related notes appearing elsewhere in this report. In addition to historical information, this discussion and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including but not limited to those identified under Item 1A. “Risk Factors”Risk Factors in this report.

Overview

Savara Inc. (together with its subsidiaries “Savara,” the “Company,” “we,” “our” or “us”) is a clinical-stage biopharmaceutical company focused on rare respiratory diseases. Our leadsole program, molgramostim, nebulizer solution (“molgramostim”), is an inhaled biologic, specifically granulocyte-macrophage colony-stimulating factor in Phase 3 development for autoimmune pulmonary alveolar proteinosis (“aPAP”). Previously, our pipeline included molgramostim for nontuberculous mycobacterial (NTM) lung infection in both non-cystic fibrosis (“CF”) and CF patients, vancomycin hydrochloride inhalation powder (“vancomycin”) for persistent methicillin-resistant Staphylococcus aureus (“MRSA”) lung infection in people living with CF and inhaled liposomal ciprofloxacin (“Apulmiq”) for non-CF bronchiectasis. Savara, together with its wholly-owned subsidiaries, which includesinclude Aravas Inc., and Savara ApS, Drugrecure A/S, and Savara Australia Pty. Limited, operate in one segment with its principal office in Austin, Texas.Langhorne, Pennsylvania, though a majority of our employees work remotely.

Since inception, we have devoted substantially all of our efforts and resources to identifying and developing our product candidates, recruiting personnel, and raising capital. We have incurred operating losses and negative cash flow from operations and have no product revenue from inception to date. From inception to December 31, 2021,2023, we have raised net cash proceeds of approximately $392.9$476.7 million, primarily from public offerings of our common stock and pre-funded warrants to acquire our common stock, private placements of convertible preferred stock, and debt financings.

We have never been profitable and have incurred operating losses in each year since inception. Our net losses were $43.0$54.7 million and $49.6$38.2 million for the years ended December 31, 20212023 and 2020,2022, respectively. As of December 31, 2021,2023, we had an accumulated deficit of $300.5$393.4 million. Substantially all of ourOur operating losses primarily resulted from expenses incurred in connection withattributed to our research and development programs and from general and administrative costs associated with our operations.

We have chosen to operate by outsourcing our manufacturing and most of our clinical operations. We expect to incur significant additional expenses and continue to incur operating losses for at least the next several years as we initiate and continue the clinical development of, and seek regulatory approval for, our product candidate. We expect that our operating losses will fluctuate significantly from quarter to quarter and year to year due to timing of clinical development programs and efforts to achieve regulatory approval.

As of December 31, 2021,2023, we had cash and cash equivalents of $34.0$26.6 million and short-term investments of $127.2$135.7 million. We willAlthough we have sufficient capital to fund many of our planned activities, we may need to continue to require substantialraise additional capital to continuefurther fund the development of, and seek regulatory approvals for, our clinical developmentproduct candidate and potential commercialization activities. Accordingly, we will needbegin to raise substantial additional capital to continue to fund our operations.commercialize any approved product. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our clinical development efforts. Failure to raise capital as and when needed, on favorable terms or at all, would have a negative impact on our financial condition and our ability to develop our product candidate.

Recent Events

COVID-19Diagnostic Testing - aPAP ClearPath™

In December 2023, we launched aPAP ClearPath™, a new serum-based blood test that can be used by physicians in the U.S. to obtain a definitive diagnosis of aPAP. The continuing COVID-19 global pandemic poses risksaPAP ClearPath™ test is a sensitive and specific quantitative immunoassay designed to our business. As we commence enrollment of our additional Phase 3 trial fordetect aPAP GM-CSF autoantibodies in human serum. The Company partnered with Trillium Health, a modern health solutions provider and a Clinical Laboratory Improvement Amendments (CLIA)-certified lab, to develop the use of molgramostim for the treatmentsimple, no-cost, and noninvasive test. A supporting disease awareness campaign was also launched to improve understanding of aPAP, there remainshighlight the hallmark signs and symptoms of the disease, and educate physicians about the need for early testing. The Company expects to roll out a general uncertainty regarding the impact of COVID-19 on the aPAP patient populationhealthcare provider disease awareness campaign and physicians. Patients suffering from aPAP lung disease are prone to underlying lung conditions and are often treated by infectious disease specialists and pulmonologists. These treating physicians are on the front linesGM-CSF autoantibody blood test in addressing this global pandemic and must now, understandably, focus their attention on COVID-19. Further, if an aPAP patient enrolled in the study were to contract COVID-19, they may need to discontinue their participation.Europe during 2024.

Additionally, we are unable to quantify the impact this situation will have on our future financial performance, but the public health actions being undertaken to reduce the spread of the virus have created, and may continue to create, challenges and disruptions to our operations. Management, on an on-going basis, is evaluating our liquidity position, communicating with and monitoring the actions of our service providers, manufacturers, and suppliers and reviewing our near-term financial performance as we manage Savara through the uncertainty related to COVID-19.ATM Sale

In response to the COVID-19 pandemic, many governments are taking measures to provide aid and economic stimulus. These measures include deferring the due dates of tax paymentssupply chain disruptions or other changes to their income and non-income-based tax laws. The Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act”), which was enacted on March 27, 2020increased costs in the U.S., includes many measures to assist companies, including temporary changes to income and non-income-based tax laws.future.

Additionally, the CARES Act provides for non-income tax provisions, such as allowing paymentsContinued Funding of the employer share of Social Security payroll taxes that would otherwise be due from the date of enactment through December 31, 2020 to be paid over the following two years.

On AugustJanuary 18, 2024, the U.S. Congress passed a third continuing resolution ("CR") for fiscal year 2024, H.R. 2872, the “Further Additional Continuing Appropriations and Other Extensions Act, 2024,” to avoid a partial government shutdown, which President Biden signed on January 19, 2024. The new CR extends the "laddered" approach from the current CR, with certain appropriations bills expiring on March 1, 2024 through March 8, 2020, former President Trump issued2024. Additionally, the U.S. Congress is currently trying to pass legislation consisting of a COVID-19 relief executive order (“EO”) intendingpackage of six spending bills to help alleviate the hardships experienced by American workers ascontinue funding a resultbroad portion of the pandemic.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses. On an ongoing basis, we evaluate these estimates and judgments. We base our estimates on historical experience and on various assumptions that we believe to be reasonable under the circumstances. These estimates and assumptions form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results may differ materially from these estimates. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates. Refer to Note 2. Summary of Significant Accounting Policies in the notes to our consolidated financial statements in this Annual Reportannual report on Form 10-K for additional discussion.

Accrued Research and Development Expenses

We record the costs associated with research, nonclinical and clinical trials, and manufacturing development as incurred. These costs are a significant component of our research and development expenses, with a substantial portion of our on-going research and development activities conducted by third party service providers, including contract research and manufacturing organizations.

52

We accrue for expenses resulting from obligations under agreements with CROs, CMOs, and other outside service providers for which payment flows do not match the periods over which materials or services are provided to us. Accruals are recorded based on estimates of services received and efforts expended pursuant to agreements established with CROs, CMOs, and other outside service providers. These estimates are typically based on contracted amounts applied to the proportion of work performed and determined through analysis with internal personnel and external service providers as to the progress or stage of completion of the services. We make significant judgments and estimates in determining the accrual balance in each reporting period. In the event advance payments are made to a CRO, CMO, or outside service provider, the payments will be recorded as a prepaid asset which will be amortized or expensed as the contracted services are performed. As actual costs become known, we adjust our prepaids and accruals. Inputs, such as the services performed, the number of patients enrolled, or the trial duration, may vary from our estimates, resulting in adjustments to research and development expense in future periods. Changes in these estimates that result in material changes to our accruals could materially affect our results of operations. To date, we have not experienced any material deviations between accrued and actual research and development expenses.

Goodwill and Acquired In-Process Research and DevelopmentIPR&D

In accordance with ASC Topic 350, Intangibles – Goodwill and Other, our IPR&D and goodwill, when applicable,present, is determined to have indefinite lives and, therefore, is not amortized. Instead, it is tested for impairment annually and between annual tests if we become aware of an event or a change in circumstances that would indicate the carrying value may be impaired. For instance, based upon the ultimate scope and scale of the COVID-19 global pandemic, there may be materially negative impacts to the assumptions made with respect to our IPR&D assets that could result in an impairment of such assets.

With respect to the impairment testing of acquired IPR&D, ASU 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment, and ASU 2012-02, Intangibles – Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment, provide us a two-step impairment process with the option to first assess qualitative factors to determine whether the existence of events or circumstances leads us to determine that it is more-likely-than not (that is, a likelihood of more than 50%) that our acquired IPR&D is impaired. If we choose to first assess qualitative factors and we determine that it is more-likely-than not acquired IPR&D is not impaired, we are not required to take further action to test for impairment.

ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, outlines an impairment model providing us the option to implement a one-step method for determining impairment of goodwill, thereby simplifying the subsequent measurement of goodwill by eliminating Step 2 (quantitative calculation of measuring a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill) from the goodwill impairment test. Under the amendments in this guidance, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable.

When we perform a quantitative assessment of acquired IPR&D, we compare its carrying value to its estimated fair value to determine whether an impairment exists. In previous years, due to a lack of Level 1 or Level 2 inputs, the Multi-Period Excess Earnings Method (“MPEEM”), which is a form of the income approach, was used to estimate the fair value of acquired IPR&D when performing a quantitative assessment. Under the MPEEM, the fair value of an intangible asset is

equal to the present value of the asset’s projected incremental after-tax cash flows (excess earnings) remaining after deducting the market rates of return on the estimated value of contributory assets (contributory charge) over its remaining useful life. We evaluate potential impairment of our acquired IPR&D annually on September 30, utilizing a qualitative approach and determining if it was more-likely-than not that the fair value was impaired. We evaluate potential impairment of our acquired goodwill, if any, annually on June 30, performing the quantitative analysis based upon market capitalization.

Our determinations as to whether, and if so, the extent to which goodwill and acquired IPR&D become impaired are highly judgmental and, in the case of applying the MPEEM approach to estimate fair value, are based on significant assumptions regarding our projected future financial condition and operating results, changes in the manner of our use of the acquired assets, development of our acquired assets or our overall business strategy, and regulatory, market, and economic environment and trends.

If the associated research and development effort is abandoned, the related asset will be written-off, and we will record a non-cash impairment loss on our consolidated statements of operations and comprehensive loss. For those products that reach commercialization, the IPR&D asset will be amortized over its estimated useful life.

Product Revenue

We record revenue based on a five-step model in accordance with ASC 606, Revenue from Contracts with Customers. To date, we have not generated any product revenue from our product candidates.

Milestone Revenue

With respect to the license agreement related to molgramostim, which includes certain milestone payments to be remunerated to us by the licensee, we identify the performance obligations, determine the transaction price, allocate the contract transaction price to the performance obligations, and recognize the revenue when (or as) the performance obligation is satisfied. We identify the performance obligations included within the license agreement and evaluate which performance obligations are distinct.

The milestone payments are a form of variable consideration as the payments are contingent upon achievement of a substantive event. The milestone payments are estimated and included in the transaction price when we determine, under the variable consideration constraint, that it is probable that there will not be a significant reversal of cumulative revenue recognized in future periods. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which we recognize revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, we re-evaluate the probability of achievement of such milestones and any related constraint, and if necessary, adjust the estimate of the overall transaction price.

Share-based Compensation Expenses

We recognize the cost of stock-based awards granted to employees based on the estimated grant-date fair value of the awards. The value of the award is recognized as expense ratably over the requisite service period. We recognize the compensation costs for awards that vest over several years on a straight-line basis over the vesting period. Forfeitures are recognized when they occur, which may result in the reversal of compensation costs in subsequent periods as the forfeitures arise. In addition, we account for any modifications to stock-based awards in accordance with ASC Topic 718, Compensation – Stock Compensation.

We estimate the grant-date fair value of a stock option award using the Black-Scholes-Merton option pricing model (“Black-Scholes model”). In determining the grant-date fair value of a stock option award under the Black-Scholes model, we must make a number of assumptions, including the term of the award, the volatility of the price of our common stock over the term of the award, and the risk-free interest rate. Changes in these or other assumptions could have a material impact on the compensation expense we recognize.

Income Taxes

We use the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities will be recognized in the period that includes the enactment date. A valuation allowance is established against the deferred tax assets to reduce their carrying value to an amount that is more-likely-than not to be realized.

Financial Operations Overview

Research and Development Expenses

We recognize research and development expenses as they are incurred. These expenses consist primarily of the following:

The largest component of our operating expenses has historically been our investment in research and development activities. The following table shows our research and development expenses by product candidate for the years ended December 31, 2021 and 2020:

We expect research and development expenses will remain significant in the future as we advance our molgramostim product candidate into and through clinical trials and pursue regulatory approvals, which will require a significant increased investment in regulatory support and contract manufacturing activities, including investing in the development of a second source manufacturer and inventory build-up related costs.clinical supplies.

The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. We may never succeed in timely developing and achieving regulatory approval for our product candidates.candidate. The probability of success of our product candidatescandidate may be affected by numerous factors, including clinical data, competition, intellectual property rights, manufacturing capability, and commercial viability. As a result, we are unable to accurately determine the duration and completion costs of our development projects or when and to what extent we will generate revenue from the commercialization and sale of molgramostim.

General and Administrative Expenses

General and administrative (“G&A”) expenses consist primarily of salaries, benefits, and related costs for personnel in executive, finance and accounting, legal, and investor relations; as well as professional and consulting fees for accounting, legal, investor relations, business development, human resources, and information technology services. Other G&A expenses include facility lease and insurance costs.

Other Income (Expense), Net

Other income (expense) includes amortization expense related to capitalized debt issuance costs and debt discount under our amended loan agreementAmended Loan Agreement with Silicon Valley Bank.

Future Funding Requirements

We have not generated any revenue from product sales. We do not know when, or if, we will generate any revenue from product sales. We do not expect to generate any revenue from product sales unless and until we obtain regulatory approval for and commercialize our product candidate. At the same time, we expect our expenses to increase in connection with our ongoing development and manufacturing activities, particularly as we continue the research, development, manufacture, and clinical trials of, and seeking regulatory approval for, our product candidate. In addition, subject to obtaining regulatory approval of our product candidate, we anticipate we may need additional funding in connection with our continuing operations.

As of December 31, 2021,2023, we had cash, cash equivalents, and short-term investments of $161.2$162.3 million. Although we have sufficient capital to fund our planned activities, including those discussed in Note 11.10. Commitments -– Manufacturing and Other of the consolidated financial statements in this Annual Report,annual report on Form 10-K, we may need to raise additional capital to further fund the development of, and seek regulatory approvals for, our product candidate and to begin commercialization of any approved product. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our clinical development efforts. Failure to raise capital as and when
