Rhea-AI Filing Summary

Invivyd, Inc. reported higher product revenue but significantly larger losses for the quarter ended March 31, 2026. Revenue rose to $13.7 million from $11.3 million, driven by sales of its COVID-19 antibody PEMGARDA. Operating costs climbed sharply, with research and development at $30.7 million and selling, general and administrative at $25.1 million, leading to a net loss of $41.4 million, up from $16.3 million a year earlier.

Cash and cash equivalents fell to $184.2 million from $226.7 million at year-end, with operating cash outflows of $41.7 million in the quarter and an accumulated deficit of $995.9 million. Management states there is substantial doubt about the company’s ability to continue as a going concern beyond one year without additional financing. Invivyd continues advancing its pipeline, including Phase 3 trials for COVID-19 antibody VYD2311 and preclinical RSV and measles programs, while also maintaining access to an undrawn senior loan facility and an at-the-market equity program.

Positive

  • None.

Negative

  • Going concern uncertainty: Management concludes there is substantial doubt about Invivyd’s ability to continue as a going concern beyond one year without additional financing, reflecting high losses, significant cash burn and limited current funding visibility.

Insights

Losses and cash burn rise, and management raises a going concern warning.

Invivyd increased product revenue to $13.7M, but expenses surged, with research and development of $30.7M and selling, general and administrative costs of $25.1M. This produced a quarterly net loss of $41.4M and operating cash outflows of $41.7M.

Cash and cash equivalents fell to $184.2M as of March 31, 2026, while accumulated deficit approached $995.9M. Management explicitly states there is substantial doubt about the ability to continue as a going concern beyond one year without new capital, a material financial risk.

The company is simultaneously advancing late-stage COVID-19 antibody VYD2311, with Phase 3 DECLARATION data anticipated in Q3 2026, and progressing RSV and measles candidates toward IND readiness in 2026. Actual impact will depend on clinical outcomes and success raising capital through equity, the undrawn $30M loan facility, or other sources.

emergency use authorization regulatory
"the Company received emergency use authorization (“EUA”) from the U.S. Food and Drug Administration"
A regulatory emergency use authorization allows a government health agency to temporarily permit the use or sale of a medical product—such as a vaccine, test, or treatment—before full formal approval when there is a public health crisis. For investors, an authorization can rapidly open revenue and market access while carrying higher regulatory and demand risk, like a fast-track pass that speeds a product to customers but may still require further review and can affect a company's valuation and future sales prospects.
Fast Track designation regulatory
"The FDA has granted “Fast Track” designation for VYD2311 for the prevention of COVID-19"
A "fast track designation" is a process that speeds up the review and approval of a product or project, allowing it to reach the market or be completed more quickly than usual. For investors, it can signal that a product may become available sooner, potentially leading to earlier revenue or benefits, and indicating a priority status that might influence company performance and market opportunities.
Biologics License Application regulatory
"DECLARATION is designed to support potential Biologics License Application (“BLA”) submission"
A biologics license application is a formal request submitted to regulatory authorities seeking approval to market a new biological medicine, such as vaccines or treatments made from living organisms. It is a comprehensive review process that evaluates the safety, effectiveness, and manufacturing quality of the product. For investors, receiving approval signals that a biological therapy can be sold to the public, potentially leading to revenue growth and market success.
going concern financial
"there is substantial doubt about its ability to continue as a going concern"
A going concern is a business that is expected to continue its operations and meet its obligations for the foreseeable future, rather than shutting down or selling off assets. This assumption matters to investors because it indicates stability and ongoing profitability, making the business a more reliable investment. Think of it as believing a restaurant will stay open and serve customers, rather than closing down suddenly.
at-the-market offerings financial
"offer and sell shares of its common stock, with a sales value of up to $75.0 million, in transactions deemed to be “at the market offerings”"
An at-the-market offering is a method for a company to sell new shares of its stock directly into the stock market over time, rather than all at once. This approach allows the company to raise money gradually, similar to selling small portions of a product as demand grows. For investors, it can influence stock availability and price, making it an important factor to consider when assessing a company's financial strategy.

INVIVYD, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Nature of the Business and Basis of Presentation

Invivyd, Inc. (the “Company”) is a biopharmaceutical company focused on the discovery, development and commercialization of monoclonal antibody (“mAb”) therapies for the prevention and treatment of serious viral infectious diseases, beginning with SARS-CoV-2, the virus that causes COVID-19, and expanding into other high-need indications, such as respiratory syncytial virus (“RSV”) and measles.

 

On March 22, 2024, the Company received emergency use authorization (“EUA”) from the U.S. Food and Drug Administration (“FDA”) for PEMGARDA® injection, for intravenous use, a half-life extended investigational mAb, for the pre-exposure prophylaxis (prevention) of COVID-19 in adults and adolescents (12 years of age and older weighing at least 40 kg) who have moderate-to-severe immune compromise due to certain medical conditions or receipt of certain immunosuppressive medications or treatments and are unlikely to mount an adequate immune response to COVID-19 vaccination.

 

In January 2024, the Company nominated VYD2311, a next generation mAb candidate for COVID-19, as a drug candidate. VYD2311 is a mAb with high in vitro neutralization potency shown against prominent SARS-CoV-2 variants tested to date. In October 2025, the Company announced that the FDA cleared the Company’s Investigational New Drug (“IND”) application for VYD2311 and provided feedback to advance the Company’s REVOLUTION clinical program, Invivyd’s development program for VYD2311. The REVOLUTION clinical program includes three clinical trials, DECLARATION, LIBERTY, and DRUMMER. In December 2025, the Company initiated DECLARATION, which is a Phase 3 randomized, triple-blind, placebo-controlled clinical trial to evaluate VYD2311 safety and efficacy in prevention of symptomatic, RT-PCR-confirmed COVID-19 at three months, with either a single dose or monthly doses of VYD2311, each administered via intramuscular injection, compared to placebo. DECLARATION is designed to support potential Biologics License Application (“BLA”) submission, with top-line data anticipated in the third quarter of 2026. In February 2026, the Company announced alignment with the FDA on LIBERTY, which is designed as a Phase 3, randomized, double-blind clinical trial to evaluate the safety, serum virus neutralizing antibody responses, and pharmacokinetics of (1) VYD2311, (2) an mRNA COVID vaccine, and (3) co-administered VYD2311 with an mRNA COVID vaccine. Additionally, the Company has agreed with the FDA on an initial Pediatric Study Plan for an efficient safety and immunobridging clinical trial to support potential BLA for VYD2311 in children aged 0-11 years. This DRUMMER pediatric clinical trial will be actioned only if the pivotal DECLARATION clinical trial is successful. The FDA has granted “Fast Track” designation for VYD2311 for the prevention of COVID-19 in individuals with underlying risk factors for progression to severe disease. Fast Track designation is a process designed to facilitate the development and expedite the regulatory review of drugs to treat serious conditions and fill an unmet medical need, including eligibility for priority review and rolling review of BLA submissions, if specified criteria are met.

In addition to the Company’s COVID-19 programs, in November 2025, the Company announced the selection of VBY329, a potential best-in-class mAb candidate being developed for the prevention of RSV infections in neonates, infants and children. The Company expects to advance VBY329 toward IND readiness in the second half of 2026. Also, in April 2026, the Company announced the discovery and advancement of VMS063, a novel, highly potent, half-life-extended, high resistance barrier measles mAb candidate. The Company has begun IND-enablement and regulatory outreach to support rapid VMS063 development, with the goal of expedited development with target IND readiness in late 2026. Through the Company’s proprietary technology platform, the Company continues to investigate additional mAbs for protection and treatment of other important infectious diseases.

 

The Company was incorporated in the State of Delaware in June 2020. The Company operates as a hybrid company with employees working at its corporate headquarters in New Haven, Connecticut, and remotely. The Company leases dedicated laboratory and office space in Newton, Massachusetts for research and development purposes.

 

The Company is subject to a number of risks and uncertainties common to companies in the biopharmaceutical industry, including, but not limited to, completing clinical trials, the ability to raise additional capital to fund operations, obtaining regulatory authorization or approval for product candidates, risks associated with market acceptance and commercialization of products, competition from other products, protection of proprietary intellectual property, compliance with government regulations, dependence on key personnel, the ability to attract and retain qualified employees, and reliance on third-party organizations for the discovery, manufacturing, clinical and commercial success of its product candidates.

Substantial Doubt about Ability to Continue as a Going Concern

The accompanying condensed consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets, and the satisfaction of liabilities and commitments in the ordinary course of business. The Company has primarily funded its operations with proceeds from sales of convertible preferred stock, proceeds from the Company’s initial public offering

5


 

(“IPO”), net proceeds received from shares of common stock sold under the Sales Agreement (as defined below) and net proceeds received from shares of common stock and pre-funded warrants sold under the Underwriting Agreements (as defined below). After receiving EUA in March 2024, the Company has also funded its operations from sales of PEMGARDA.

The Company has incurred recurring losses and negative cash flows from operations since its inception, including a net loss of $41.4 million for the three months ended March 31, 2026. As of March 31, 2026, the Company had an accumulated deficit of $995.9 million. The Company may continue to generate operating losses for the foreseeable future.

Based on current operating plans and excluding future external financing, the Company will not have sufficient cash and cash equivalents to fund its operating expenses and capital requirements beyond one year from the issuance of these condensed consolidated financial statements, and therefore, the Company has concluded that there is substantial doubt about its ability to continue as a going concern.

The Company will require additional funding through a combination of contribution from revenues, equity offerings, government or private-party grants, debt financings or other capital sources, such as collaborations with other companies, strategic alliances or licensing arrangements to finance its future operations. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaborations or other arrangements. The terms of any financing may adversely affect the holdings or rights of the Company’s stockholders.

If the Company is unable to obtain sufficient capital, the Company will be forced to delay, reduce or eliminate some or all of its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all. The accompanying condensed consolidated financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classification of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

The accompanying condensed consolidated financial statements include the accounts of Invivyd, Inc. and its wholly owned subsidiaries, Invivyd Security Corporation and Invivyd Netherlands B.V. All intercompany accounts and transactions have been eliminated in consolidation. The Company views its operations and manages its business in one operating segment, which is the business of discovering, developing and commercializing differentiated products for the prevention and treatment of infectious diseases.

Unaudited Interim Financial Information

The accompanying condensed consolidated balance sheet as of March 31, 2026, the condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2026 and 2025, the condensed consolidated statements of cash flows for the three months ended March 31, 2026 and 2025 and the condensed consolidated statements of stockholders’ equity for the three months ended March 31, 2026 and 2025 are unaudited.

The accompanying unaudited condensed consolidated financial statements as of March 31, 2026 and for the three months ended March 31, 2026 and 2025 have been prepared by the Company pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial statements. The accompanying condensed consolidated balance sheet as of December 31, 2025 was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited annual consolidated financial statements, and the notes thereto, as of and for the year ended December 31, 2025, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC on March 5, 2026 (the “2025 Form 10-K”).

In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s condensed consolidated financial position as of March 31, 2026 and December 31, 2025, the condensed consolidated results of operations for the three months ended March 31, 2026 and 2025, the condensed consolidated cash flows for the three months ended March 31, 2026 and 2025, and changes in stockholders’ equity for the three months ended March 31, 2026 and 2025 have been made. The Company’s condensed consolidated results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2026.

2. Summary of Significant Accounting Policies

As of March 31, 2026, the Company’s significant accounting policies and estimates, which are detailed in the Company’s 2025 Form 10-K, have not materially changed.

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, research and development expenses and related prepaid or accrued costs, stock-based compensation expense, revenue, including discounts and allowances, and inventory obsolescence. The Company bases its estimates on historical experience, known trends, expected future internal sales forecasts and other market-specific or relevant factors it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates as there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ materially from those estimates or assumptions. If actual market conditions are less favorable than those projected by management or in the event of an adverse FDA action, inventory write-downs may be required.

Concentrations of Credit Risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist of cash, cash equivalents and accounts receivable. As of March 31, 2026, the Company invested its excess cash in money market funds that are subject to minimal credit and market risks. The Company maintains its existing cash and cash equivalents at two accredited financial institutions. From time to time, these deposits may exceed federally insured limits. The Company has not experienced any losses historically in these accounts. Accordingly, the Company does not believe it is exposed to unusual credit risk related to its existing cash and cash equivalents beyond the normal credit risk associated with commercial banking relationships.

There have been no material changes in customer concentration of accounts receivable from those detailed in the Company’s 2025 Form 10-K. As of March 31, 2026, the Company recorded an allowance for doubtful accounts of $0.3 million related to one direct customer.

The Company is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and will remain an emerging growth company until December 31, 2026. For so long as the Company remains an emerging growth company, it is permitted and intends to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. For example, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of these accounting standards until they would otherwise apply to private companies.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”). The new standard requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statement. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The Company is currently evaluating the potential impact of ASU 2024-03 on its consolidated financial statement disclosures.

3. Fair Value Measurements

Fair Value Measurements

Certain assets of the Company are carried at fair value under U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

 

 

Level 1 — Quoted prices in active markets for identical assets or liabilities.

 

 

 

Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.

 

 

 

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

 

7


 

The Company’s cash equivalents are carried at fair value, determined according to the fair value hierarchy described above. The carrying values of the Company’s accounts payable and accrued expenses approximate their fair values due to the short-term nature of these liabilities.

The following tables present the Company’s fair value hierarchy for its assets and liabilities that are measured at fair value on a recurring basis (in thousands):

7. License and Collaboration Agreements

Adimab Assignment Agreement

In July 2020, the Company entered into an Assignment and License Agreement (the “Adimab Assignment Agreement”) with Adimab, LLC (“Adimab”). Under the terms of the agreement, Adimab assigned to the Company all rights, title and interest in and to certain of its coronavirus-specific antibodies (each, a “CoV Antibody” and together, the “CoV Antibodies”), including modified or derivative forms thereof, and related intellectual property. In addition, Adimab granted to the Company a non-exclusive, worldwide, royalty-bearing, sublicensable license to certain of its platform patents and technology for the development, manufacture and commercialization of the CoV Antibodies and pharmaceutical products containing or comprising one or more CoV Antibodies (each, a “Product”) for all indications and uses, with the exception of certain diagnostic uses and use as a research reagent (the “Field”). The Company is entitled to sublicense the assigned rights and licensed intellectual property solely with respect to any CoV Antibody or Product, subject to specified conditions of the agreement. The Company is obligated to use commercially reasonable efforts to achieve specified development and regulatory milestones for Products in certain major markets and to commercialize a product in any country in which the Company obtains marketing approval.

Pursuant to the terms of the Adimab Assignment Agreement, the parties will establish one or more work plans that set forth the activities to be performed under the agreement (each, a “Work Plan”), and each party is responsible for performing the obligations to which it is assigned under such Work Plans. Upon execution of the Adimab Assignment Agreement, the Company and Adimab agreed on an initial Work Plan that outlined the services that will be performed commencing at inception of the arrangement. The Company is obligated to pay Adimab quarterly for its services performed under each Work Plan at a specified full-time equivalent rate. Otherwise, the Company is solely responsible for the development, manufacture and commercialization of the CoV Antibodies and associated Products at its own cost and expense. The Company is solely responsible for preparing and submitting all IND applications, new drug applications, biologics license applications and other regulatory filings for the CoV Antibodies and Products in the Field, and for obtaining and maintaining all marketing approvals for Products in the Field, at its sole expense. Additionally, the Company has the sole right to prosecute, maintain, enforce and defend patents covering the CoV Antibodies and Products, all at its own expense.

Amounts paid with respect to services performed by Adimab on the Company’s behalf under the Adimab Assignment Agreement are recognized as research and development expense as such amounts are incurred. During both the three months ended March 31, 2026 and 2025, the Company did not recognize any research and development expense with respect to services performed by Adimab on the Company’s behalf under the Adimab Assignment Agreement. Please refer to Note 15 for additional information.

The Company is obligated to pay Adimab up to $16.5 million upon the achievement of specified development and regulatory milestones for the first Product under the agreement that achieves such specified milestones and up to $8.1 million upon the achievement of specified development and regulatory milestones for the second Product under the agreement that achieves such specified milestones. The maximum aggregate amount of milestone payments payable under the agreement for any and all Products is $24.6 million, of which a total of $11.1 million has been achieved and paid through March 31, 2026; however, milestone payments do not accrue for certain in vitro diagnostic devices consisting of or containing CoV Antibodies.

The next potential milestone under the Adimab Assignment Agreement is a low single-digit million-dollar regulatory milestone, which was not considered probable under U.S. GAAP and therefore, no expense was recognized as of March 31, 2026.

During both the three months ended March 31, 2026 and 2025, the Company did not recognize any in-process research and development (“IPR&D”) expense with respect to contingent consideration payable under the Adimab Assignment Agreement. Except for milestone payments of $11.1 million incurred through December 31, 2023, no other milestone payments have been paid to or have been earned by Adimab through March 31, 2026.

The Company is obligated to pay Adimab royalties of a mid-single-digit percentage based on net sales of any Products, beginning upon the first commercial sale of a Product in accordance with the Adimab Assignment Agreement. The royalty rate is subject to reductions specified under the agreement. Royalties are due on a Product-by-Product and country-by-country basis beginning upon the first commercial sale of each Product and ending on the later of (i) 12 years after the first commercial sale of such Product in such country and (ii) the expiration of the last valid claim of a patent covering such Product in such country (the “Royalty Term”). During

9


 

the three months ended March 31, 2026 and 2025, the Company expensed $0.6 million and $0.5 million of royalties, respectively, while reserving all rights under the Adimab Assignment Agreement and the applicable law. In addition, the Company is obligated to pay Adimab royalties of a specified percentage in the range of 45% to 55% of any compulsory sublicense consideration received by the Company in lieu of certain royalty payments.

Unless earlier terminated, the Adimab Assignment Agreement remains in effect until the expiration of the last-to-expire Royalty Term for any and all Products. The Company may terminate the agreement at any time for any or no reason upon advance written notice to Adimab, or in the event of a material breach by Adimab that is not cured with specific periods. Adimab may only terminate the agreement for an uncured material breach by the Company for its due diligence obligation or a payment obligation. Upon any termination of the agreement prior to its expiration, all licenses and rights granted pursuant to the arrangement will automatically terminate and revert to the granting party and all other rights and obligations of the parties will terminate.

The Company concluded that the Adimab Assignment Agreement represented an asset acquisition of IPR&D assets with no alternative future use. The arrangement did not qualify as a business combination because substantially all of the fair value of the assets acquired was concentrated in a single asset.

Adimab Collaboration Agreement

In May 2021, the Company entered into a Collaboration Agreement with Adimab, as amended in November 2022 and September 2023 (the “Adimab Collaboration Agreement”), for the discovery and optimization of proprietary antibodies as potential therapeutic product candidates. Under the Adimab Collaboration Agreement, the Company and Adimab could collaborate on research programs for a specified number of targets selected by the Company within a specified time period. Under the Adimab Collaboration Agreement, Adimab granted the Company a worldwide, non-exclusive license to certain of its platform patents and technology and antibody patents to perform the Company’s responsibilities during the ongoing research period and for a specified evaluation period thereafter (the “Evaluation Term”). In addition, the Company granted Adimab a license to certain of the Company’s patents and intellectual property solely to perform Adimab’s responsibilities under the research plans. Under the Adimab Collaboration Agreement, the Company has an exclusive option, on a program-by-program basis, to obtain licenses and assignments to commercialize selected products containing or comprising antibodies directed against the applicable target, which option may be exercised upon the payment of a specified option fee for each program. Upon exercise of an option by the Company, Adimab will assign to the Company all right, title and interest in the antibodies of the optioned research program and will grant the Company a worldwide, royalty-free, fully paid-up, non-exclusive, sublicensable license under the Adimab platform technology for the development, manufacture and commercialization of the antibodies for which the Company has exercised its options and products containing or comprising those antibodies. The Company is obligated to use commercially reasonable efforts to develop, seek marketing approval for, and commercialize one product that contains an antibody discovered in each optioned research program.

The Company agreed to pay Adimab a quarterly fee of $1.3 million, which could be cancelled at the Company’s option at any time. For so long as the Company was paying such quarterly fee (or earlier if (i) the Company experienced a change of control after the third anniversary of the Adimab Collaboration Agreement or (ii) Adimab owned less than a specified percentage of the Company’s equity), Adimab and its affiliates agreed not to assist or direct certain third parties to discover or optimize antibodies intended to bind to coronaviruses or influenza viruses. Under the Adimab Collaboration Agreement, the Company could also elect to decrease the scope of Adimab’s exclusivity obligations and obtain a corresponding decrease in the quarterly fee. In December 2023, the Company elected to decrease the scope of Adimab’s exclusivity obligations to cover only coronaviruses and obtained a corresponding decrease in the quarterly fee. Effective January 2024, the Company became obligated to pay Adimab a quarterly fee of $0.6 million. During both the three months ended March 31, 2026 and 2025, the Company recognized $0.6 million of research and development expense related to the quarterly fee.

For each agreed upon research program that is commenced, the Company is obligated to pay Adimab quarterly for its services performed during a given research program at a specified full-time equivalent rate; a discovery delivery fee of $0.2 million; and an optimization completion fee of $0.2 million. For each option exercised by the Company to commercialize a specific research program, the Company is obligated to pay Adimab an exercise fee of $1.0 million. Amounts paid with respect to services performed by Adimab on the Company’s behalf in each of the research programs under the Adimab Collaboration Agreement are recognized as research and development expense as such amounts are incurred and services are rendered. During both the three months ended March 31, 2026 and 2025, the Company did not recognize any research and development expense with respect to services performed by Adimab on the Company’s behalf under the Adimab Collaboration Agreement. During both the three months ended March 31, 2026 and 2025, the Company did not recognize any IPR&D expense related to drug delivery fees, optimization completion fees or option exercise fees. Please refer to Note 15 for additional information.

The Company is obligated to pay Adimab up to $18.0 million upon the achievement of specified development and regulatory milestones for each product under the Adimab Collaboration Agreement that achieves such milestones. The next potential milestone under the Adimab Collaboration Agreement is a low single-digit million-dollar clinical milestone, which was not considered probable under U.S. GAAP and therefore, no expense was recognized as of March 31, 2026. The Company is also obligated to pay Adimab royalties of a mid-single-digit percentage based on net sales of any product under the Adimab Collaboration Agreement, subject to

10


 

reductions for third-party licenses. The royalty term will expire for each product on a country-by-country basis upon the later of (i) 12 years after the first commercial sale of such product in such country and (ii) the expiration of the last valid claim of any patent claiming composition of matter or method of making or using any antibody identified or optimized under the Adimab Collaboration Agreement in such country.

In addition, the Company is obligated to pay Adimab for Adimab’s performance of certain validation work with respect to certain antigens acquired from a third party. In consideration for this work, the Company is obligated to pay Adimab royalties of a low single-digit percentage based on net sales of products that contain such antigens for the same royalty term as antibody-based products, but the Company is not obligated to make any milestone payments for such antigen products. Through March 31, 2026, no royalty payments have been paid to or have been earned by Adimab under the Adimab Collaboration Agreement.

The Adimab Collaboration Agreement will expire (i) if the Company does not exercise any option, upon the conclusion of the last Evaluation Term for the research programs, or (ii) if the Company exercises an option, on the expiration of the last royalty term for a product in a particular country, unless the agreement is earlier terminated. The Company may terminate the Adimab Collaboration Agreement at any time upon advance written notice to Adimab. In addition, subject to certain conditions, either party may terminate the Adimab Collaboration Agreement in the event of a material breach by the other party that is not cured within specified periods.

The Company concluded that the Adimab Collaboration Agreement represented an asset acquisition of IPR&D with no alternative future use. Therefore, payments made by the Company to Adimab for milestones achieved will be recognized as IPR&D expense in the related period in which the services are performed or the related milestone is considered probable of achievement. Amounts paid with respect to services performed by Adimab on the Company’s behalf under the Adimab Collaboration Agreement are recognized as research and development expense as such amounts are incurred and services are rendered. Please refer to Note 15 for additional information.

Adimab Platform Transfer Agreement

In September 2022 (the “Adimab Platform Transfer Agreement Effective Date”), the Company entered into a Platform Transfer Agreement with Adimab (the “Adimab Platform Transfer Agreement”) under which the Company was granted the right under certain intellectual property of Adimab to practice certain elements of Adimab’s platform technology, including B-cell cloning using Adimab’s proprietary yeast cell lines and other antibody optimization libraries, trade secrets, protocols and software of Adimab, to discover, engineer and optimize antibodies. The Company does not have access to Adimab’s proprietary discovery libraries. The Company was also granted the right under certain intellectual property of Adimab to research, develop, make, sell and exploit such antibodies and products containing such antibodies. The Adimab platform has been transferred to the Company in accordance with the terms of the Adimab Platform Transfer Agreement. In September 2022, the Company recognized $3.0 million as IPR&D expense in connection with the upfront consideration payable for the rights assigned pursuant to the Adimab Platform Transfer Agreement.

The Company is obligated to pay Adimab an annual fee of single digit millions on each of the first four anniversaries of the Adimab Platform Transfer Agreement Effective Date, which allows the Company to receive material improvements to the platform technology, including materially improved antibody optimization libraries, updates that provide new functionality to the platform, and software upgrades, from Adimab through June 2027. The first annual fee became due in September 2023 and was paid in October 2023. During both the three months ended March 31, 2026 and 2025, the Company recognized $0.5 million of research and development expense related to the annual fee under the Adimab Platform Transfer Agreement. Beginning in July 2027 and ending in June 2042, unless terminated earlier, the Company has the option to receive additional material improvements to the platform technology from Adimab, subject to a commercially reasonable fee to be negotiated by the parties.

The Company is obligated to pay Adimab up to $9.5 million upon the achievement of specified development and regulatory milestones for each product under the Adimab Platform Transfer Agreement that achieves such milestones. The next potential milestone under the Adimab Platform Transfer Agreement is a mid-six-digit dollar preclinical milestone, which was not considered probable under U.S. GAAP and therefore, no expense was recognized as of March 31, 2026.

In addition, the Company is obligated to pay Adimab royalties of a low single-digit percentage based on net sales of products containing an antibody discovered, engineered or optimized using Adimab’s platform technology, subject to reductions specified under the Adimab Platform Transfer Agreement. Royalties are due on a product-by-product and country-by-country basis. The royalty term will expire for each product on a country-by-country basis upon the later of (i) 12 years after the first commercial sale of such product in such country and (ii) the expiration of the last valid claim of a program antibody patent for covering the program antibody contained in such product in such country. Through March 31, 2026, no royalty payments have been paid to or have been earned by Adimab under the Adimab Platform Transfer Agreement.

The Company may terminate the Adimab Platform Transfer Agreement at any time upon advance written notice to Adimab. In addition, subject to certain conditions, either party may terminate the Adimab Platform Transfer Agreement in the event of a material breach by the other party that is not cured within specified periods or in connection with the other party’s insolvency.

11


 

The Company concluded that the Adimab Platform Transfer Agreement represented an asset acquisition of IPR&D with no alternative future use. Therefore, payments made by the Company to Adimab for milestones achieved will be recognized as IPR&D expense in the related period in which the services are performed or the related milestone is considered probable of achievement. Amounts paid with respect to the annual material improvement fees are recognized as research and development expense as such amounts are incurred. Please refer to Note 15 for additional information.

WuXi Biologics Cell Line License Agreement

In December 2020, as amended in February 2023, March 2024 and March 2026, the Company entered into a Cell Line License Agreement with WuXi Biologics (Hong Kong) Limited (“WuXi Biologics”) (the “Cell Line License Agreement”), under which WuXi Biologics granted to the Company a non-exclusive, non-transferable, worldwide, royalty-bearing, sublicensable license to certain of its intellectual property, including certain patent rights associated with a proprietary cell line developed by WuXi Biologics for the exploitation of certain recombinant antibodies developed using such proprietary cell line (each, a “Licensed Product”). Each Licensed Product generated under the arrangement will be produced from a transformed or transfected version of the proprietary cell line derived by WuXi Biologics (each of such transformed or transfected cell lines, a “Licensed Cell Line”).

In December 2020, the Company recognized an upfront fee of $0.2 million upon completion of cell bank generation for the first Licensed Cell Line created under the Cell Line License Agreement.

The Company is also obligated to pay royalties in the range of less than 1.0% to WuXi Biologics based on net sales of any Licensed Products manufactured by the Company or a third party on its behalf. However, if the Company uses WuXi Biologics to manufacture all of its commercial supplies for Licensed Products, no royalties would be owed by the Company to WuXi Biologics for net sales of Licensed Products. The Company has an option to buy out its royalty obligations on a Licensed Cell Line-by-Licensed Cell Line basis with respect to certain Licensed Products by making a one-time payment in the low eight-figures to WuXi Biologics and with respect to certain other Licensed Products by making a one-time payment in the middle-seven figures to WuXi Biologics. Royalties are due on a Licensed Product-by-Licensed Product basis commencing on the date of the first commercial sale of the applicable product and continuing for so long as the Company commercializes Licensed Products or, if earlier, until the Company exercises its option to buy out the royalty obligations. The royalty obligation shall be waived to the extent the royalty obligation is derived or arising from a Licensed Product sold in the U.S. if the Company’s ability to have such Licensed Product manufactured by WuXi Biologics becomes materially restricted due to certain government actions, with such waiver continuing for so long as such government action continues. Through March 31, 2026, no royalties had become due to WuXi Biologics.

The Cell Line License Agreement remains in effect until it is terminated. The Company may terminate the Cell Line License Agreement at any time with notice to WuXi Biologics. WuXi Biologics may terminate the Cell Line License Agreement in the event the Company fails to make a payment when due under the Cell Line License Agreement and such non-payment is not cured within a specified period after notice. Either party may terminate the Cell Line License Agreement in the event of a material breach by the other party that is not cured within a specified period after notice. Upon termination of the Cell Line License Agreement, the license conveyed by WuXi Biologics to the Company will continue in full force and effect with respect to all Licensed Products manufactured using the Licensed Cell Line already generated under the Cell Line License Agreement, provided that the Company continues to pay its royalty obligations, if any.

The Company concluded that the Cell Line License Agreement represented an asset acquisition of IPR&D with no alternative future use. The Cell Line License Agreement did not qualify as a business combination because substantially all of the fair value of the assets acquired was concentrated in a single asset. The Company did not recognize any IPR&D expense under the Cell Line License Agreement during the three months ended March 31, 2026 and 2025.

8. Population Health Partners, L.P.

In November 2022 (the “PHP Effective Date”), the Company entered into a Master Services Agreement with Population Health Partners, L.P. (“PHP”), pursuant to which PHP agreed to provide services and create deliverables for the Company as agreed between the Company and PHP and set forth in one or more work orders under such agreement (the “PHP MSA”). The term of the PHP MSA commenced on the PHP Effective Date for an initial term of one year. The PHP MSA renewed for subsequent periods, until terminated in accordance with its terms. The PHP MSA was terminated effective July 2024. On the PHP Effective Date, the Company and PHP entered into the first work order under the PHP MSA (the “PHP Work Order”), pursuant to which PHP agreed to advise and counsel the Company regarding clinical development and regulatory matters with respect to the Company’s product candidates. The PHP Work Order was effective for six months from the PHP Effective Date and terminated in accordance with its terms in May 2023. The PHP MSA contained customary confidentiality provisions and representations and warranties of the parties, as well as mutual non-solicitation of certain employees during the term of the PHP MSA and for a period of one year thereafter.

As compensation for the services and deliverables under the PHP Work Order, the Company paid PHP a cash fee of $0.5 million per month during the term of the PHP Work Order for an aggregate fee of $3.0 million (the “Aggregate Fee”).

During both the three months ended March 31, 2026 and 2025, the Company did not pay any cash compensation to PHP and therefore did not recognize any research and development expense related thereto.

12


 

In addition to the cash compensation, on the PHP Effective Date, the Company issued a warrant to purchase shares of the Company’s common stock to PHP (the “PHP Warrant”). The exercise price of the PHP Warrant is $3.48 per share of the Company’s common stock, which was equal to the Nasdaq official closing price of a share of the Company’s common stock on the trading day immediately prior to the PHP Effective Date. The PHP Warrant is exercisable for up to an aggregate of 6,824,712 shares of the Company’s common stock, and vests in three separate tranches as follows:

3,591,954 shares of the Company’s common stock underlying the PHP Warrant vests if the Company’s Market Capitalization (as defined below) equals or exceeds $758,517,511 by November 15, 2028;

 

 

 

 

 

1,795,977 shares of the Company’s common stock underlying the PHP Warrant vests if the Company’s Market Capitalization equals or exceeds $1,137,776,266 by November 15, 2029; and

 

 

 

 

 

1,436,781 shares of the Company’s common stock underlying the PHP Warrant vests if the Company’s Market Capitalization equals or exceeds $1,517,035,022 by November 15, 2030.

For purposes of the PHP Warrant, the term “Market Capitalization” means, with respect to a particular trading day, the total value of the outstanding shares of the Company’s common stock on such date, calculated by multiplying the Company’s volume weighted-average price for the ten (10) trading days immediately preceding such date by the Company’s total number of outstanding shares of the Company’s common stock as reflected in (i) the Company’s most recent periodic or annual report filed with the SEC (e.g., Annual Report on Form 10-K or Quarterly Report on Form 10-Q), as the case may be, (ii) a more recent public announcement by the Company or (iii) a more recent written notice by the Company or the Company’s transfer agent setting forth the number of shares of the Company's common stock outstanding. As of March 31, 2026, no portion of the PHP Warrant had vested.

The PHP Warrant is exercisable for ten years from the PHP Effective Date with respect to the vested portion(s) of the PHP Warrant. The PHP Warrant may be exercised by cash exercise or, at the election of PHP, by means of “cashless exercise” pursuant to a formula set forth in the PHP Warrant. The Company also granted PHP certain “piggyback” registration rights requiring the Company to register any shares of the Company’s common stock underlying the PHP Warrant for resale with the SEC, subject to the Company’s existing obligations under that certain Second Amended and Restated Investors’ Rights Agreement, dated April 16, 2021, by and among the Company and the investors party thereto, which registration rights PHP exercised in January 2024.

Upon the consummation of a fundamental transaction of the Company (as defined in the PHP Warrant) on or prior to November 15, 2028, all of the shares underlying the PHP Warrant would become immediately vested and exercisable; upon the consummation of a fundamental transaction of the Company after November 15, 2028 but on or prior to November 15, 2029, the shares underlying the second and third tranches of the PHP Warrant would become immediately vested and exercisable; and upon the consummation of a fundamental transaction of the Company after November 15, 2029 but on or prior to November 15, 2030, the shares underlying the third tranche of the PHP Warrant would become immediately vested and exercisable.

Refer to Note 11 for additional information on the PHP Warrant.

Tamsin Berry, a member of the Company’s board of directors, is a Limited Partner of PHP.

9. Commitments and Contingencies

Operating Lease Commitments

In June 2022, the Company entered into a two-year noncancelable agreement for dedicated laboratory and office space in Newton, Massachusetts (the “Newton, MA Lease”), which was amended in September 2022. Pursuant to the amended Newton, MA Lease, the Company entered into a two-year noncancelable agreement for new dedicated laboratory and office space in Newton, Massachusetts, on the same campus as, and in lieu of, the space leased under the original lease. The Company took occupancy of the new dedicated laboratory and office space in December 2022. The amended Newton, MA Lease provided for monthly rental payments, including base rent charges of $1.3 million per year. In August 2024 and May 2025, the Newton, MA Lease was further amended to extend the lease through December 2027, with an option to further extend the lease for an additional twenty-four months or continue the lease on a month-to-month basis after completion of the term ending in December 2027.

In February 2026, the Company further amended the Newton, MA Lease to add additional dedicated laboratory space, which commenced on March 1, 2026. The amendment provides for incremental annual base rent of $0.3 million for the remainder of the lease term, through December 2027.

In May 2025, the Company entered into a short-term lease agreement for approximately 13,600 square feet of office space in New Haven, Connecticut, with an original term of 12 months. The Company has elected the short-term lease recognition exemption under ASC Topic 842 – Leases and therefore has not recognized a right-of-use asset or lease liability on the balance sheet. For the three months ended March 31, 2026, base rent charges of less than $0.1 million were incurred. There were no related expenses incurred for the three months ended March 31, 2025.

In January 2026, the Company entered into an agreement to lease approximately 33,000 square feet of office space in New Haven, Connecticut (the “New Haven Lease”). The New Haven Lease commenced in March 2026 and has an initial term of one hundred twenty-nine months. The Companys obligation for the payment of rent for the premises begins six months after the lease commencement date and total future minimum lease payments are expected to be $10.9 million. The lease includes a tenant improvement allowance of approximately $1.0 million.

Under the terms of the New Haven Lease, the Company made a security deposit of $1.0 million in the form of a letter of credit, which will be reduced by 50% in September 2027, following the first twelve months of rent payments.

License Agreements

The Company has entered into license agreements with Adimab and WuXi Biologics (see Note 7).

Other Contracts

The Company enters into agreements with third parties in the ordinary course of business for various products and services, including those related to research, preclinical and clinical operations, manufacturing and support, supply chain, and distribution. These contracts do not contain any material minimum purchase commitments. Certain of these agreements provide for termination rights subject to the payment of termination fees and/or wind-down costs. Under such agreements, the Company is contractually obligated to make certain payments to vendors upon early termination, primarily to reimburse them for their unrecoverable outlays incurred prior to cancellation as well as any amounts owed by the Company prior to early termination. The actual amounts the Company could pay in the future to the vendors under such agreements may differ from the purchase order amounts due to cancellation provisions. The termination fees were not probable of payment as of March 31, 2026 and December 31, 2025.

Legal Proceedings

From time to time, the Company may become involved in legal proceedings or other litigation relating to claims arising in the ordinary course of business. The Company accrues a liability for such matters when it is probable that future expenditures will be made and that such expenditures can be reasonably estimated. Significant judgment is required to determine both probability and estimated exposure amount. Legal fees and other costs associated with such proceedings are expensed as incurred. As of March 31, 2026, the Company was not a party to any material legal proceedings.

Indemnification Agreements

In the ordinary course of business, the Company may provide indemnification of varying scope and terms to its vendors, lessors, contract research organizations, contract development and manufacturing organizations, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with members of its board of directors and its executive officers that require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or executive officers. The maximum potential amount of future payments that the Company could be required to make under these indemnification agreements is, in many cases, unlimited. The Company has not incurred any material costs as a result of such indemnifications and is not currently aware of any indemnification claims.

Loan Agreement

On April 18, 2025, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank, a division of First-Citizens Bank & Trust Company, as lender (the “Lender”). The Loan Agreement provides for a senior secured term loan facility in an aggregate principal amount of up to $30 million (the “Term Facility”) consisting of (a) Term A Loans in an aggregate principal amount of up to $10 million, which shall be available to be drawn from and after August 15, 2025 through December 31, 2026 upon compliance with certain financial covenants and conditions, (b) Term B Loans in an aggregate principal amount of up to $10 million, which shall be available to be drawn during the period commencing on the date of the achievement of certain net product revenue milestones and ending on June 30, 2027, and (c) Term C Loans in an aggregate principal amount of up to $10 million, which shall be available to be drawn during the period commencing on the date of the achievement of certain net product revenue milestones and ending on June 30, 2027. The proceeds of the Term Facility may be used for working capital and general business purposes. As of March 31, 2026, the Company had not satisfied certain financial covenants and conditions, including the net product revenue milestone required to be eligible to access proceeds from the Term Facility. Accordingly, as of March 31, 2026, no amounts have been drawn down under the Loan Agreement.

The loans under the Term Facility are due and payable on March 1, 2029 and bear interest that is payable monthly, commencing with the month in which any loans are funded under the Term Facility, in arrears at a per annum rate, subject to increase during an Event of Default (as defined in the Loan Agreement), equal to the greater of (x) the Wall Street Journal prime rate minus 0.25%, subject to a 9.00% cap, and (y) 6.00%. Commencing on April 1, 2027, which date may be extended to April 1, 2028 upon the achievement of certain net product revenue milestones (the “Interest-Only Period Extension”), the Company will be required to repay the principal of the Term Facility in 24 consecutive equal monthly installments or, in the case of the Interest-Only Period Extension, 12 consecutive equal monthly installments. At maturity, or if earlier prepaid, the Company will also be required to pay a final payment fee equal to 4.50% of the aggregate principal amount of the loans advanced under the Term Facility. The Loan Agreement provides for an unused term loan commitment fee equal to 1.00% of the Term Facility upon the earliest to occur of (a) July 1, 2027, (b) the occurrence of an Event of Default under the Loan Agreement and (c) the termination of the Loan Agreement; provided, that such fee will be waived by the Lender in the event that the Company has requested and the Lender has funded any loans under the Term Facility prior to such date.

10. Common Stock

Shelf Registration Statements

In September 2022, the Company filed a shelf registration statement on Form S-3 with the SEC and an accompanying base prospectus, which was declared effective by the SEC on October 5, 2022, for the offer and sale of up to $400 million of the Company’s securities (the “2022 Shelf Registration Statement”). The 2022 Shelf Registration Statement expired upon the effectiveness of the 2025 Shelf Registration Statement (as defined below).

In October 2025, the Company filed a new shelf registration statement on Form S-3 with the SEC and an accompanying base prospectus, which was declared effective by the SEC on December 23, 2025, for the offer and sale of up to $350 million of the Company’s securities (the “2025 Shelf Registration Statement”).

15


 

ATM Prospectus Supplement (as defined below), $275 million of the Company’s securities remained available for offer and sale under the 2025 Shelf Registration Statement.

August 2025 Underwritten Public Offering

In August 2025, the Company completed an underwritten public offering pursuant to an underwriting agreement (the “August Underwriting Agreement”) with Cantor Fitzgerald & Co. (“Cantor”), as representative of the underwriters named therein, pursuant to which it issued and sold an aggregate of 89,234,480 shares of its common stock at a price of $0.52 per share, and pre-funded warrants to purchase up to an aggregate of 21,342,442 shares of common stock at a price of $0.5199 per pre-funded warrant (the “August 2025 Underwritten Public Offering”). The price of $0.5199 per pre-funded warrant represented the $0.52 per share purchase price for the common stock less the exercise price of $0.0001 per pre-funded warrant. The pre-funded warrants are exercisable at any time after their original issuance and will not expire. The Company received total net proceeds of approximately $53.5 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company. As of March 31, 2026, there were no exercises of pre-funded warrants that were issued in connection with the August 2025 Underwritten Public Offering.

November 2025 Underwritten Public Offering

In November 2025, the Company completed an underwritten public offering pursuant to an underwriting agreement (the “November Underwriting Agreement” and together with the August Underwriting Agreement, the “Underwriting Agreements”) with Cantor, as representative of the underwriters named therein, pursuant to which it issued and sold an aggregate of 44,000,000 shares of its common stock at a price of $2.50 per share, and pre-funded warrants to purchase up to an aggregate of 6,000,000 shares of common stock at a price of $2.4999 per pre-funded warrant (the “November 2025 Underwritten Public Offering”, and, together with the August 2025 Underwritten Public Offering, the “2025 Underwritten Public Offerings”). The price of $2.4999 per pre-funded warrant represented the $2.50 per share purchase price for the common stock less the exercise price of $0.0001 per pre-funded warrant. The pre-funded warrants are exercisable at any time after their original issuance and will not expire. The Company received total net proceeds of approximately $117.2 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company. As of March 31, 2026, there were no exercises of pre-funded warrants that were issued in connection with the November 2025 Underwritten Public Offering.

In December 2025, and in connection with the November 2025 Underwritten Public Offering, Cantor exercised the option pursuant to the November Underwriting Agreement to purchase 4,675,000 additional shares of common stock at the public offering price of $2.50, less underwriting discounts and commissions. In connection with such exercise, the Company received total net proceeds of approximately $10.9 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company.

ATM Facility

In December 2023, the Company entered into a Controlled Equity OfferingSM Sales Agreement (the “Sales Agreement”) with Cantor, as sales agent, and filed with the SEC a prospectus supplement (the “2023 ATM Prospectus Supplement”) to the 2022 Shelf Registration Statement, pursuant to which the Company could, at its option, offer and sell shares of its common stock, with a sales value of up to $75.0 million, from time to time, through Cantor, acting as sales agent, in transactions deemed to be “at the market offerings”, as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). Cantor was entitled to a commission of 3% of the gross proceeds from any sales of such shares. In 2024, the Company sold 9,000,000 shares of its common stock under the Sales Agreement and the 2023 ATM Prospectus Supplement, at an average price of $4.50 per share for $39.3 million in proceeds net of commissions. In 2025, the Company sold 23,055,402 shares of its common stock under the Sales Agreement and the 2023 ATM Prospectus Supplement at an average price of $1.49 per share for $33.4 million in proceeds net of commissions. Upon the effectiveness of the 2025 Shelf Registration Statement, all offers and sales under the 2023 ATM Prospectus Supplement were deemed terminated.

In October 2025, in connection with the filing of the 2025 Shelf Registration Statement, the Company filed with the SEC a new prospectus supplement (the “2025 ATM Prospectus Supplement”), pursuant to which the Company may, at its option, offer and sell shares of its common stock, with a sales value of up to $75.0 million, from time to time, through Cantor, acting as sales agent, in transactions deemed to be “at the market offerings”, as defined in Rule 415 under the Securities Act. Cantor is entitled to a commission of 3% of the gross proceeds from any sales of such shares. The 2025 Shelf Registration Statement was declared effective by the SEC on December 23, 2025, and $75.0 million remained available for sale under the 2025 ATM Prospectus Supplement as of March 31, 2026.

In April 2026, the Company sold 11,803,589 shares of its common stock under the Sales Agreement at an average price of $1.70 per share for $19.4 million in proceeds net of commissions.

11. Stock-Based Compensation

2020 Equity Incentive Plan

The Company’s 2020 Equity Incentive Plan (the “2020 Plan”) provides for the Company to grant incentive stock options, non-qualified stock options, restricted stock awards, RSUs and other stock-based awards to employees, members of the board of directors and consultants. The 2020 Plan is administered by the board of directors or, at the discretion of the board of directors, by a committee of the board of directors. The board of directors may also delegate to one or more officers of the Company the power to grant awards to

16


 

employees and certain officers of the Company. The exercise prices, vesting and other restrictions are determined at the discretion of the board of directors, or its committee or any such officer if so delegated.

The exercise price for stock options granted may not be less than the fair market value of the Company’s common stock on the date of grant, as determined by the board of directors, or at least 110% of the fair market value of the Company’s common stock on the date of grant in the case of an incentive stock option granted to an employee who owns stock representing more than 10% of the voting power of all classes of stock as determined by the board of directors as of the date of grant. Prior to the IPO, the Company’s board of directors determined the fair value of the Company’s common stock, taking into consideration its most recently available valuation of common stock performed by third parties as well as additional factors which may have changed since the date of the most recent contemporaneous valuation through the date of grant. Stock options granted under the 2020 Plan expire after ten years and typically vest over a four-year period with the first 25% vesting upon the first anniversary of a specified vesting commencement date and the remainder vesting in 36 equal monthly installments over the succeeding three years, contingent on the recipient’s continued employment or service. Certain awards of stock options permit the holders to exercise the option in whole or in part prior to the full vesting of the option in exchange for unvested shares of restricted common stock with respect to any unvested portion of the option so exercised.

As of March 31, 2026, there were 467,615 shares authorized to be issued upon the exercise of outstanding stock options and no shares reserved for future issuance under the 2020 Plan.

2021 Equity Incentive Plan

In July 2021, the Company’s board of directors adopted, and its stockholders approved, the 2021 Equity Incentive Plan (the “2021 Plan”), which became effective immediately prior to and contingent upon the execution of the underwriting agreement related to the Company’s IPO. The 2021 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, RSUs and other stock-based awards. The number of shares initially reserved for issuance under the 2021 Plan was equal to 35,075,122, which was the sum of 11,413,572 new shares; plus the number of shares (not to exceed 23,661,550 shares), which represented (i) the number of shares that remained available for issuance under the 2020 Plan, at the time the 2021 Plan became effective, and (ii) any shares subject to outstanding stock options or other stock awards that were granted under the 2020 Plan that are forfeited, terminate, expire or are otherwise not issued. In December 2024, the 2021 Plan was amended by Amendment No. 1 to the 2021 Plan, which decreased the aggregate number of shares of the Company’s common stock reserved for issuance under the 2021 Plan by 8,000,000 shares. In addition, the number of shares of the Company’s common stock reserved for issuance under the 2021 Plan will automatically increase on the first day of each calendar year pursuant to the evergreen provision thereof, beginning on January 1, 2022 and continuing through January 1, 2031, in an amount equal to 5% of the shares of common stock outstanding on the last day of the calendar month before the date of each automatic increase, or a lesser number of shares determined by the board of directors. On January 1, 2022, 5,539,145 shares of common stock were automatically added to the shares authorized for issuance under the 2021 Plan pursuant to the evergreen provision thereof. On January 1, 2024, 3,304,820 shares of common stock were added to the shares authorized for issuance under the 2021 Plan, pursuant to the evergreen provision thereof, as determined by the Company’s board of directors. On January 1, 2026, 14,099,351 shares of common stock were added to the shares authorized for issuance under the 2021 Plan, pursuant to the evergreen provision thereof, as determined by the Company’s board of directors. The number of shares to be issued under the 2021 Plan did not increase pursuant to the evergreen provision thereof on January 1, 2023 nor January 1, 2025, as determined by the Company’s board of directors. The shares of common stock underlying any awards that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, repurchased or are otherwise terminated by the Company under the 2021 Plan will be added back to the shares of common stock available for issuance under the 2021 Plan.

As of March 31, 2026, there were an aggregate of 28,946,439 shares authorized to be issued upon the exercise of outstanding stock options and vesting of RSU grants and 19,574,167 shares reserved for future issuance under the 2021 Plan.

2026 Inducement Plan

In January 2026, the Company’s board of directors adopted the 2026 Inducement Plan (the “2026 Inducement Plan”). Under the 2026 Inducement Plan, the Company is authorized to issue up to 8,000,000 shares pursuant to inducement grants. The only persons eligible to receive grants under the 2026 Inducement Plan are individuals who satisfy the standards for inducement grants under Nasdaq Listing Rule 5635(c)(4) and the related guidance under Nasdaq IM 5635-1, including individuals who were not previously an employee or director of the Company (or individuals following a bona fide period of non-employment), in each case as an inducement material to such individual’s agreement to enter into employment with the Company. The 2026 Inducement Plan provides for the discretionary grant of nonstatutory stock options, stock appreciation rights, restricted stock awards, RSUs, performance awards, and certain other awards.

As of March 31, 2026, there were an aggregate of 192,000 shares authorized to be issued upon the exercise of outstanding stock options and 7,808,000 shares reserved for future issuance under the 2026 Inducement Plan.

Stock Option Valuation

The fair value of stock option grants is estimated using the Black-Scholes option-pricing model. Prior to its IPO in August 2021, the Company had been a private company. Due to the proximity to the IPO, the Company continues to lack sufficient company-specific

17


 

historical and implied volatility information. Therefore, it estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded stock price. For options with service-based vesting conditions, the expected term of the Company’s stock options has been determined utilizing the “simplified” method. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.

The following table presents, on a weighted-average basis, the assumptions used in the Black-Scholes option-pricing model to determine the grant date fair value of stock options granted:

The weighted-average grant date fair value of stock options granted during the three months ended March 31, 2026 and 2025 was $1.19 and $0.93, respectively, per share.

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and the fair market value of the common stock for the options that had exercise prices lower than the estimated fair value of the Company’s common stock at March 31, 2026 and 2025.

The total intrinsic value of stock options exercised was less than $0.1 million for both the three months ended March 31, 2026 and 2025.

Restricted Stock Unit Activity

In February and September 2025, the Company’s board of directors approved RSU grants to the Company’s executive officers and certain of its employees under the 2021 Plan. In February 2025, an aggregate of 1,700,000 RSUs were issued at a grant date fair value of $1.61 per share. In September 2025, an aggregate of 400,000 RSUs were issued at a grant date fair value of $1.15 per share. All RSU grants are scheduled to vest over an eighteen-month period, with one-third of the RSUs vesting every six months following the relevant grant date, subject to continuous service as of each vesting date.

In July 2021, the Company’s board of directors adopted, and its stockholders approved, the 2021 Employee Stock Purchase Plan (the “2021 ESPP”), which became effective immediately prior to and contingent upon the execution of the underwriting agreement related to the Company’s IPO. A total of 1,342,773 shares of common stock were initially reserved for issuance under the 2021 ESPP. The number of shares of common stock that may be issued under the 2021 ESPP will automatically increase on the first day of each calendar year, pursuant to the evergreen provision thereof, beginning on January 1, 2022 and continuing through January 1, 2031, by an amount equal to the lesser of (i) 1% of the shares of common stock outstanding on the last day of the calendar month before the date of each automatic increase, (ii) 2,685,546 shares and (iii) an amount determined by the Company’s board of directors. The number of shares to be issued under the 2021 ESPP did not increase pursuant to the evergreen provision thereof on January 1, 2023, January 1, 2024, nor January 1, 2025, as determined by the Company’s board of directors. On January 1, 2026, the number of shares authorized for issuance under the 2021 ESPP increased by 2,685,546 shares of common stock, pursuant to the evergreen provision thereof. The first offering under the 2021 ESPP was June 6, 2022. As of March 31, 2026, 3,101,681 shares remained available for issuance under the 2021 ESPP. There were 926,638 shares issued under the 2021 ESPP as of March 31, 2026. During both the three months ended March 31, 2026 and 2025, the Company recognized less than $0.1 million in related stock-based compensation expense.

Warrant Expense

In November 2022, the Company entered into the PHP MSA, the PHP Work Order and a warrant agreement with respect to the PHP Warrant. To compensate for the services and deliverables provided by PHP, the Company issued 6,824,712 equity-classified warrants to PHP. Each warrant shall give the right to acquire common stock of the Company at a purchase price of $3.48 per share. Per the agreement, the PHP Warrant is exercisable upon either the achievement of corresponding market capitalization targets or a consummation of a fundamental transaction (as defined in the PHP Warrant); as such, there are no other requirements, including any continuous service requirements, in order for PHP to be entitled to the PHP Warrant, if and when any portion of it vests.

The aggregate grant date fair value of the PHP Warrant was $17.4 million, which was recognized as warrant expense on the grant date in November 2022.

There were no warrants issued during the three months ended March 31, 2026 and 2025.

As of March 31, 2026, other than the pre-funded warrants issued in the 2025 Underwritten Public Offerings, there were 6,824,712 warrants outstanding and not yet vested at a weighted-average exercise price of $3.48, with a weighted-average remaining contractual term of 6.63 years.

12. Income Taxes

For both the three months ended March 31, 2026 and 2025, the Company recorded no income tax benefits for the net operating losses incurred or for the research and development tax credits generated in each period, due to its uncertainty of realizing a benefit from those items. Substantially all of the Company’s operating losses since inception have been generated in the U.S.

13. Defined Contribution Plan

The Company maintains a 401(k) Plan (the “401(k) Plan”) for the benefit of eligible employees. The 401(k) Plan is a defined contribution plan under Section 401(k) of the Internal Revenue Code of 1986, as amended, that covers all employees who meet defined minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. Pursuant to the terms of the 401(k) Plan, the Company is required to make non-elective contributions of 3% of eligible participants’

19


 

compensation. For the three months ended March 31, 2026 and 2025, the Company contributed $0.3 million and $0.2 million, respectively, to the 401(k) Plan.

14. Net Loss per Share

Basic and diluted net loss per share attributable to common stockholders was calculated as follows (in thousands, except share and per share amounts):

The 27,342,442 shares of common stock issuable upon exercise of pre-funded warrants described in Note 10 are included as outstanding common stock in the calculation of net loss per common share.

The Company’s potential dilutive securities have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted-average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the periods indicated, because including them would have had an anti-dilutive effect:

16. Segment Reporting

The Company operates as a single reportable and operating segment dedicated to the research and development, commercialization, and sale of mAbs in the U.S. to deliver protection from serious viral infectious diseases.

The determination of a single reportable segment is consistent with the consolidated financial information regularly reviewed by the Chief Operating Decision Maker (the “CODM”) in assessing performance and deciding how to allocate resources on a consolidated basis.

The CODM assesses performance and allocates resources based on the Company’s net loss reported on the consolidated statements of operations and comprehensive loss. The CODM’s area of focus is period over period fluxes and budget-to-actual variances when assessing performance and deciding how to allocate resources. The Company’s reportable segment derives its revenue from sales of its product, PEMGARDA. No asset information has been provided for the reportable segment as the CODM does not regularly review asset information by reportable segment.

The following table presents information about reported segment revenues, and significant segment expenses as provided to the CODM (in thousands). Certain prior period segment expense amounts have been recast to reflect the current year presentation.

Overview

Invivyd, Inc. is a biopharmaceutical company focused on the discovery, development and commercialization of monoclonal antibody (“mAb”) therapies for the prevention and treatment of serious viral infectious diseases. We are devoted to delivering protection from serious viral infectious diseases, beginning with SARS-CoV-2, the virus that causes COVID-19. PEMGARDA® (pemivibart) is our first mAb to receive regulatory authorization and was designed to exert continuous pharmaceutical activity in the face of viral evolution.

Globally, COVID-19 has caused millions of deaths and lasting health problems in many survivors and remains a significant global health concern, particularly for immunocompromised individuals. COVID-19 persists and continues to impact patients, notably those who are immunocompromised, and combating this disease will require for years to come a variety of prevention and treatment options with demonstrated efficacy and safety. By leveraging our capabilities, which we have developed through our experience with adintrevimab and pemivibart and over five years in the COVID-19 space, we aim to develop mAbs that could be used in prevention or treatment of serious viral infectious diseases, starting with COVID-19 and expanding into other high-need indications, such as respiratory syncytial virus (“RSV”) and measles.

On March 22, 2024, we received emergency use authorization (“EUA”) from the U.S. Food and Drug Administration (“FDA”) for PEMGARDA injection, for intravenous (“IV”) use, a half-life extended investigational mAb, for the pre-exposure prophylaxis (prevention) of COVID-19 in adults and adolescents (12 years of age and older weighing at least 40 kg) who have moderate-to-severe immune compromise due to certain medical conditions or receipt of certain immunosuppressive medications or treatments and are unlikely to mount an adequate immune response to COVID-19 vaccination. Recipients should not be currently infected with or have had a known recent exposure to an individual infected with SARS-CoV-2.

The emergency use of PEMGARDA is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic under Section 564(b)(1) of the Federal Food, Drug, and Cosmetic Act (“FDCA”), 21 U.S.C. § 360bbb-3(b)(1), unless the declaration is terminated or authorization revoked sooner. PEMGARDA is authorized for use only when the combined national frequency of variants with substantially reduced susceptibility to PEMGARDA is less than or equal to 90%, based on available information including variant susceptibility to PEMGARDA and national variant frequencies. 

In January 2024, we nominated VYD2311, a next generation mAb candidate for COVID-19, as a drug candidate. VYD2311 is a mAb with high in vitro neutralization potency shown against prominent SARS-CoV-2 variants tested to date. In September 2024, we announced dosing of the first participants in a Phase 1/2 clinical trial of VYD2311. The Phase 1/2 randomized, blinded, placebo-controlled clinical trial evaluated escalating dosing as well as safety, tolerability, pharmacokinetics and immunogenicity of VYD2311 in healthy trial participants. The Phase 1/2 clinical trial was conducted in Australia and evaluated multiple dose levels of VYD2311 through various routes of administration, including exploration of intramuscular (“IM”) administration and subcutaneous administration, which are designed to be more healthcare system- and patient-friendly than IV administration. In June 2025, we announced positive full Phase 1/2 clinical data for VYD2311 for both safety and

24


 

pharmacokinetics. Like pemivibart, VYD2311 was engineered from adintrevimab, our investigational mAb that has a robust safety data package and demonstrated clinically meaningful results in global Phase 2/3 clinical trials for both the prevention and treatment of COVID-19.

In August 2025, we announced alignment with advice from the FDA on a compact and, therefore, rapid pathway to potential Biologics License Application (“BLA”) approval for VYD2311 for the prevention of COVID-19. As part of Type C meeting feedback, the FDA advised that a single, randomized, placebo-controlled trial evaluating mAb efficacy in prevention of RT-PCR-confirmed symptomatic COVID-19 disease events could support a BLA submission for VYD2311 for the prevention of COVID-19 in a broad population of Americans (12 years of age and older, weighing at least 40kg), including immunocompromised people, subject to agreement on safety database size and pending full protocol review. In October 2025, we announced that the FDA cleared our Investigational New Drug (“IND”) application for VYD2311 and provided feedback to advance our REVOLUTION clinical program, which is our development program for VYD2311. The REVOLUTION clinical program includes three clinical trials, DECLARATION, LIBERTY and DRUMMER.

In December 2025, we initiated DECLARATION, which is a Phase 3 randomized, triple-blind, placebo-controlled clinical trial to evaluate VYD2311 safety and efficacy in prevention of symptomatic, RT-PCR-confirmed COVID-19 at three months, with either a single dose or monthly doses of VYD2311, each administered via IM injection, compared to placebo. In April 2026, we announced that we conducted a prospectively designed, conservative, algorithmic sample size re-estimation pooled, blinded analysis for the DECLARATION clinical trial aimed at ensuring adequate COVID-19 clinical events and associated statistical power given the variability of COVID-19 attack rates. As of the sample-size re-estimation analysis, conducted when the first 1,500 (of 1,818 total) subjects reached Day 45, clinical events accrued to date could support statistical powering for the high end of anticipated VYD2311 efficacy levels with approximately half of the base DECLARATION clinical trial still to go. The sample size re-estimation was designed conservatively with the aim of accomplishing strong statistical power to accommodate a range of potential VYD2311 efficacy results and COVID events in the trial, and upsizing was triggered. The DECLARATION upsizing includes approximately 500 additional subjects, in addition to 1,818 total randomized subjects in the initial trial population. DECLARATION is designed to support potential BLA submission. Depending on recruitment rates following the trial upsizing, top-line data from DECLARATION are expected in the third quarter of 2026.

In February 2026, we announced alignment with the FDA on LIBERTY, which is designed as a Phase 3, randomized, double-blind clinical trial to evaluate the safety, serum virus neutralizing antibody responses, and pharmacokinetics of (1) VYD2311, (2) an mRNA COVID vaccine, and (3) co-administered VYD2311 with an mRNA COVID vaccine.

Additionally, we have agreed with the FDA on an initial Pediatric Study Plan for an efficient safety and immunobridging clinical trial to support potential BLA for VYD2311 in children aged 0-11 years. This DRUMMER pediatric clinical trial will be actioned only if the pivotal DECLARATION clinical trial is successful.

The FDA has granted “Fast Track” designation for VYD2311 for the prevention of COVID-19 in individuals with underlying risk factors for progression to severe disease. Fast Track designation is a process designed to facilitate the development and expedite the regulatory review of drugs to treat serious conditions and fill an unmet medical need, including eligibility for priority review and rolling review of BLA submissions, if specified criteria are met.

In July 2025, we announced that we had formed the SPEAR (Spike Protein Elimination and Recovery) Study Group with leading investigators to structure and guide anticipated clinical trials evaluating the effects of broadly neutralizing anti-SARS-CoV-2 spike protein mAb therapy in people suffering from Long COVID or Post-Vaccination Syndrome (“PVS”). The SPEAR Study Group intends to launch multi-center translational clinical research on Long COVID and PVS using next-generation antibodies like our investigational mAb candidate VYD2311. In January 2026, we and the SPEAR Study Group announced plans to initiate a Phase 2 clinical trial evaluating VYD2311 in individuals with Long COVID or COVID vaccine injury. The Phase 2 clinical trial is expected to be initiated mid-2026.

We engage in active SARS-CoV-2 variant monitoring of antiviral activity as part of our ongoing industrial virology effort, which leverages a consistent, high-quality, independent, third-party pseudoviral system that routinely tests authentic Invivyd-produced molecules and is supported by structure-based analytics. In September 2024, we announced continued neutralizing activity of PEMGARDA against SARS-CoV-2 variants KP.3.1.1 and LB.1 and attractive neutralization potency of VYD2311, our next generation mAb candidate for COVID-19, against the same contemporary viruses, and we also provided an update to ongoing structural analysis showing no meaningful mutational change in the pemivibart binding site since the Omicron shift late in 2021. In January 2025, March 2025 and August 2025, we announced continued neutralizing activity of PEMGARDA and VYD2311 against dominant SARS-CoV-2 variants XEC, LP.8.1 and XFG, respectively. In May 2026, we announced that in vitro neutralization data showed continued neutralizing activity of PEMGARDA and VYD2311 against emerging SARS-CoV-2 variant BA.3.2.2 (“Cicada”).

In addition to our COVID-19 programs, in November 2025, we announced the selection of VBY329, a potential best-in-class mAb candidate being developed for the prevention of RSV infections in neonates, infants and children. We expect to advance VBY329 toward IND readiness in the second half of 2026. Also, in April 2026, we announced the discovery and

25


 

advancement of VMS063, a novel, highly potent, half-life-extended, high resistance barrier measles mAb candidate. We have begun IND-enablement and regulatory outreach to support rapid VMS063 development, with the goal of expedited development with target IND readiness in late 2026. Through our proprietary technology platform, we continue to investigate additional mAbs for protection and treatment of other important infectious diseases.

We are also committed to advancing national education and awareness about antibodies and their role in immune health. In April 2026, we launched Antibodies for Any Body, a national education campaign designed to elevate public understanding of antibodies, one of the most important parts of the immune system, and their role in protecting against disease. The campaign was launched in collaboration with renowned ski champion Lindsey Vonn, whose career has been defined by training with intention, overcoming challenges, and taking control of her health and wellness.

We rely on partnerships, external consultants and contract research organizations (“CROs”) to conduct discovery, nonclinical, preclinical, clinical and commercial activities. Additionally, we rely on contract testing laboratories and contract development and manufacturing organizations (“CDMOs”) to execute our chemistry, manufacturing and controls development, testing and clinical and commercial manufacturing activities. In 2022, we secured dedicated laboratory space and expanded our research team in order to enable internal discovery and development of our mAb candidates, while continuing to leverage our existing partnership with Adimab, LLC (“Adimab”), including Adimab’s platform technology. In addition, we expect to continue to rely on third parties for clinical trials and the manufacture and testing of our product candidates, as well as to perform ongoing research and development and other services on our behalf.

Since our inception and through March 31, 2026, we have financed our operations primarily through the sale and issuance of preferred and common stock, including net proceeds of $464.7 million from sales of our preferred stock, net proceeds of $327.5 million from sales of our common stock from our initial public offering (“IPO”), net proceeds of $72.7 million from sales of our common stock under the Sales Agreement (as defined below) and net proceeds of $181.6 million from sales of our common stock and pre-funded warrants under the Underwriting Agreements (as defined below). We have also funded our operations from sales of PEMGARDA. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and commercialization of one or more of our product candidates, as they become authorized or approved.

Since our inception, we have incurred significant losses, including a net loss of $41.4 million for the three months ended March 31, 2026. As of March 31, 2026, we had an accumulated deficit of $995.9 million. We may continue to incur significant expenses and recognize losses in the foreseeable future as we expand and progress our research and development activities, manufacturing activities and commercialization efforts. In addition, our losses from operations may fluctuate significantly from period to period depending on the timing of our clinical trials and our expenditures on other research and development activities, manufacturing activities, and commercialization efforts. Our expenses could increase substantially in connection with our ongoing activities, as we:

continue to commercialize PEMGARDA;
advance the development of VYD2311 and prepare for its potential commercial launch, if approved, as well as advance development of our other product candidates, such as VBY329 and VMS063;
initiate and conduct clinical trials of our product candidates, including advancement of our REVOLUTION clinical program;
develop product candidates in any new indications or patient populations;
advance our preclinical and discovery programs, such as RSV and measles, including development and screening of additional antibodies, as well as engage in ongoing SARS-CoV-2 variant monitoring and testing;
seek regulatory authorization or approval for any product candidates that successfully complete clinical trials;
pursue coverage and reimbursement for our product candidates, if authorized or approved;
acquire or in-license other product candidates, intellectual property and/or technologies;
further develop and validate our commercial-scale current Good Manufacturing Practices (“cGMP”) manufacturing process and manufacture material under cGMP at our contracted manufacturing facilities for clinical trials and commercial sales;
maintain, expand, enforce, defend and protect our intellectual property portfolio;
comply with regulatory requirements established by the applicable regulatory authorities;
maintain and expand a sales, marketing and distribution infrastructure to commercialize any product candidates for which we may obtain regulatory authorization or approval;

26


 

hire and retain personnel, including research, clinical, development, manufacturing, quality control, quality assurance, regulatory, scientific, commercial and other personnel; and
incur additional legal, accounting and other expenses in operating as a public company.

As a result, we will require additional funding through a combination of contribution from revenues, equity offerings, government or private-party grants, debt financings or other capital sources, such as collaborations with other companies, strategic alliances or licensing arrangements to support our continuing operations and pursue our growth strategy. We may be unable to secure additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we are unable to secure additional funding when needed, we could be forced to curtail our planned operations and the pursuit of our growth strategy.

Because of the numerous risks and uncertainties associated with pharmaceutical product development and emergence of SARS-CoV-2 variants, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve or maintain profitability. We may never obtain regulatory authorization or approval for any of our product candidates other than PEMGARDA. Even with product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

Based on current operating plans and excluding future external financing, we will not have sufficient cash and cash equivalents to fund our operating expenses and capital requirements beyond one year from the issuance date of the condensed consolidated financial statements in this Quarterly Report on Form 10-Q, and therefore, we have concluded that there is substantial doubt about our ability to continue as a going concern. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See the section entitled “Liquidity and Capital Resources” for more information.

Components of Our Results of Operations

Product Revenue, Net

In March 2024, we received EUA from the FDA for PEMGARDA. Product revenue, net consists of product revenue earned on the sales of PEMGARDA in the U.S. Product revenues are recognized net of variable consideration, including discounts and allowances, trade discounts and distributor fees, chargebacks, product returns and other incentives such as co-pay assistance programs.

Cost of Product Revenue

Cost of product revenue includes PEMGARDA manufacturing costs, labor and overhead costs, and stability study costs. PEMGARDA manufacturing costs include manufacturing materials, third-party manufacturing costs, packaging costs, shipping costs, and royalties.

Research and Development Expenses

The nature of our business and primary focus of our activities generates a significant amount of research and development costs. Research and development expenses represent costs incurred by us for:

the nonclinical and preclinical development of our product candidates, including our discovery efforts;
the procurement of our product candidates from a third-party manufacturer; and
the global clinical development of our product candidates.

Such costs consist of:

personnel-related expenses, including salaries, bonuses, benefits, third-party fees and other compensation-related costs, including stock-based compensation expense, for employees engaged in research and development functions;
expenses incurred under agreements with third parties, such as collaborators, consultants, contractors and CROs, that conduct the discovery, nonclinical and preclinical studies and clinical trials of our product candidates and research programs;
costs of procuring manufactured product candidates for use in nonclinical studies, preclinical studies, clinical trials and for commercial supply, prior to receiving authorization or approval, from a third-party CDMO;
costs of outside consultants and advisors, including their fees and stock-based compensation;
laboratory-related expenses, which include equipment, laboratory supplies, rent expense, depreciation expense, and other operating costs;

27


 

payments made under third-party licensing agreements; and
other expenses incurred as a result of research and development activities.

We expense research and development costs as incurred. Non-refundable advance payments that we make for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed, or when it is no longer expected that the goods will be delivered or the services rendered.

Our primary focus since inception has been the development of antibodies against COVID-19. We have also initiated discovery efforts to assess pipeline expansion beyond SARS-CoV-2, including the selection of a preclinical mAb candidate for the prevention of RSV, the selection of a preclinical mAb candidate for the prevention of measles and the advancement of early discovery programs targeting other potential targets. Our research and development costs consist primarily of external costs, such as fees paid to CDMOs, CROs and consultants in connection with our nonclinical studies, preclinical studies, clinical trials and product candidate manufacturing. To date, external research and development costs for any individual product candidate have been tracked commencing upon product candidate nomination. We do not allocate employee-related costs, costs associated with our discovery efforts and other internal or indirect costs to specific research and development programs or product candidates because these resources are used and these costs are deployed across multiple programs under development and, as such, are not separately classified.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher and more variable development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. Our research and development expenses will increase as we continue advancing VYD2311 through clinical development, particularly as we advance the REVOLUTION clinical program, pursue EUA or regulatory approval of our product candidates, and continue to discover and develop additional product candidates.

At this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the development of any of our product candidates. We are also unable to predict when, if ever, material net cash inflows will commence from sales or licensing of our product candidates. This is due to the numerous risks and uncertainties associated with drug development, including the uncertainty of:

 

the timing and progress of preclinical and clinical development activities;
the number and scope of preclinical and clinical programs we decide to pursue;
filing acceptable IND applications with the FDA or comparable foreign applications that allow commencement of our planned clinical trials or future clinical trials for our product candidates;
sufficiency of our financial and other resources to complete the necessary preclinical studies and clinical trials, manufacture the product candidates and complete associated regulatory activities;
our ability to establish and maintain agreements with third-party manufacturers for clinical supply for our clinical trials and successfully develop, obtain regulatory authorization or approval for our product candidates;
successful enrollment and timely completion of clinical trials, including our ability to generate positive data from any such clinical trials;
the costs associated with the development of any additional development programs and product candidates we identify in-house or obtain through collaborations, licenses or acquisitions;
the prevalence, nature and severity of adverse events experienced with any product candidates;
the terms and timing of any collaboration, license or other arrangement, including the terms and timing of any milestone payments thereunder;
our ability to obtain and maintain patent, trademark and trade secret protection and regulatory exclusivity for our product candidates, if and when approved, and otherwise protecting our rights in our intellectual property portfolio;
our ability to maintain compliance with regulatory requirements, including current Good Clinical Practices, current Good Laboratory Practices and cGMPs, and to comply effectively with other rules, regulations and procedures applicable to the development and sale of pharmaceutical products;
timely receipt of regulatory authorizations or approvals from applicable regulatory authorities;

28


 

potential significant and changing government regulation, regulatory guidance and requirements and evolving treatment guidelines; and
the impact of any business interruptions to our operations or those of third parties with which we work, including as a result of any public health crisis.

A change in the outcome of any of these variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others.

In emergency situations, such as a pandemic, and with a declaration of a public health emergency by the U.S. Secretary of the Department of Health and Human Services (“HHS”), the FDA has the authority to issue an EUA. While the COVID-19 public health emergency declared by HHS under the Public Health Service Act expired on May 11, 2023, this does not impact the FDA’s ability to authorize COVID-19 drugs and biological products for emergency use pursuant to the relevant declaration under Section 564 of the FDCA. On March 22, 2024, we received EUA from the FDA for PEMGARDA. There can be no assurance that the public health emergency in the U.S. declared under the FDCA will continue to be in place for an extended period of time, that any of our other product candidates will be granted an EUA by the FDA, if we apply for such an authorization, or that we would be able to maintain an EUA, such as the EUA received for PEMGARDA, for an extended period of time. The emergency use of PEMGARDA is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic under Section 564 of the FDCA, unless the declaration is terminated or authorization revoked sooner.

Acquired In-Process Research and Development Expenses

Acquired in-process research and development (“IPR&D”) expenses consist primarily of costs of contingent milestone payments incurred to acquire rights to Adimab’s antibodies relating to COVID-19 and SARS and related intellectual property and a license to certain of Adimab’s platform patents and technology (the “IPR&D assets”) for use in the research and development of our product candidates. We expensed the cost of the IPR&D assets because they had no alternative future use as of the acquisition date. We will recognize additional IPR&D expenses in the future if and when it is deemed probable that we will make contingent milestone payments to Adimab under the terms of the agreement by which we acquired the IPR&D assets.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of salaries, bonuses, benefits, third-party fees and other compensation-related costs, including stock-based compensation, for our personnel and external contractors involved in our executive, finance, legal, business development and other administrative functions, as well as our commercial function. Selling, general and administrative expenses also include costs incurred for outside services associated with such functions, including legal fees relating to patent and corporate matters; professional fees for accounting, auditing, tax and administrative consulting services; insurance costs; market research costs; and other selling, general and administrative expenses. These costs relate to the operation of the business, unrelated to the research and development function, or any individual program.

Our selling, general and administrative expenses will increase in the future as our business expands and we increase our headcount to support the expected growth in our research and development activities and the commercialization of any authorized or approved product candidates, such as PEMGARDA. We also anticipate increased expenses associated with operating as a public company, including increased costs of accounting, audit, legal, regulatory and tax-related services, director and officer insurance premiums, and investor and public relations costs. We also expect to incur additional intellectual property-related expenses as we file additional patent applications to protect innovations arising from our research and development activities.

Through March 31, 2026, we have operated as a hybrid company with employees working at our corporate headquarters and remotely. We have not incurred material operating expenses for the rent, maintenance and insurance of facilities, or for the depreciation of fixed assets.

Other Income, Net

Other income, net consists of interest income earned from our cash and cash equivalents. We expect our interest income to vary each reporting period depending on our average bank deposits, money market funds and investment balances during the period and market interest rates.

Income Taxes

Since our inception, we have not recorded any income tax expense or realized benefits for the net losses we have incurred or for the research and development tax credits generated in each period as we believe, based upon the weight of available evidence, that it is more likely than not that all of our net operating loss carryforwards and tax credit carryforwards will not be realized.

29


 

We continue to monitor the manner in which countries will enact legislation to implement the Pillar Two framework proposed by the Organisation for Economic Co-operation and Development, which proposes a 15% global corporate minimum tax. As of March 31, 2026, various countries have enacted aspects of Pillar Two while committing to enact additional aspects in future years. While we do not expect these rules to have a material impact on our effective tax rate, we continue to monitor these initiatives on a global basis.

The following discussion presents the components of our expenses for the periods presented:

Product Revenue, Net

Product revenue, net was $13.7 million and $11.3 million for the three months ended March 31, 2026 and 2025, respectively. The $2.4 million increase is the result of increased product sales of PEMGARDA due to an increase in product demand.

Cost of Product Revenue

Cost of product revenue was $1.0 million and $0.8 million for the three months ended March 31, 2026 and 2025, respectively. The $0.2 million increase is the result of increased PEMGARDA sales and certain period costs.

We began capitalizing our inventory costs in March 2024, in connection with EUA from the FDA and based upon our expectation that these costs would be recoverable through commercialization of PEMGARDA. Prior to the capitalization of our inventory costs, such costs were recorded as research and development expenses in the period incurred. Had our pre-EUA manufacturing costs been capitalized, our reported margins would approach 80%.

Research and development expenses were $30.7 million for the three months ended March 31, 2026, compared to $10.6 million for the three months ended March 31, 2025. The $20.1 million increase in research and development expenses was primarily due to the following:

Decrease in direct costs related to our pemivibart program resulted from a decrease of $0.6 million in contract research costs for our Phase 3 CANOPY clinical trial, $0.5 million in nonclinical expenses and $0.1 million in contract costs for commercial manufacturing;
Increase in direct costs related to our VYD2311 program resulted from an increase of $21.5 million in contract research costs for our Phase 3 DECLARATION clinical trial and $0.4 million in external discovery-related and other costs, partially offset by a decrease of $0.3 million in contract costs for commercial manufacturing and $0.3 million in nonclinical expenses;
Increase in direct costs related to our VBY329 program resulted from the nomination of VBY329 as an RSV mAb candidate in the fourth quarter of 2025, with costs resulting from nonclinical expenses;
Increase in direct costs for our VMS063 program resulted from the nomination of VMS063 as a measles mAb candidate in the second quarter of 2026, with costs resulting from external discovery-related and other costs;
Decrease in direct costs related to our early-stage programs resulted from a decrease of external discovery-related and other costs;
Decrease in personnel related costs resulted from a decrease of headcount-related costs; and
Decrease in external discovery-related and other costs resulted from a decrease of $0.3 million in contract manufacturing costs and $0.1 million in nonclinical costs, partially offset by an increase of $0.2 million in clinical trial expenses and $0.1 million in other external costs.

Increase in personnel related costs resulted from an increase in headcount-related costs;
Increase in professional and consultant fees resulted from an increase of $3.4 million in professional service fees and $1.7 million related to sales and marketing costs, partially offset by a decrease of $0.1 million in insurance costs; and
Increase in other costs primarily resulted from an increase of $0.7 million in employee related travel expense, $0.3 million in conference related costs and $0.2 million in technology related costs.

Other Income, net

Other income, net was $1.7 million and $0.6 million for the three months ended March 31, 2026 and 2025, respectively, consisting primarily of interest earned on our invested cash balances. The $1.1 million increase in other income, net was primarily due to an increase in cash invested.

Liquidity and Capital Resources

Sources of Liquidity

Through March 31, 2026, we have incurred significant operating losses and negative cash flows from operations. Although we received an EUA from the FDA for PEMGARDA in March 2024, we may continue to incur significant expenses and potential

31


 

operating losses for the foreseeable future as we continue to commercialize PEMGARDA and advance the development of VYD2311, VBY329, VMS063 and our other product candidates. As of March 31, 2026, we have financed our operations primarily with net proceeds of $464.7 million from sales of our preferred stock, $327.5 million from sales of our common stock from our IPO in August 2021, $72.7 million from sales of our common stock under the Sales Agreement (as defined below), and $181.6 million from sales of our common stock and pre-funded warrants under the Underwriting Agreements (as defined below). After receiving EUA in March 2024, we have also funded our operations from sales of PEMGARDA.

As of March 31, 2026, we had cash and cash equivalents of $184.2 million. In April 2026, we sold 11,803,589 shares of our common stock under the Sales Agreement at an average price of $1.70 per share for $19.4 million in proceeds net of commissions.

Shelf Registration Statements

In September 2022, we filed a shelf registration statement on Form S-3 with the SEC and an accompanying base prospectus, which was declared effective by the SEC on October 5, 2022, for the offer and sale of up to $400 million of our securities (the “2022 Shelf Registration Statement”). The 2022 Shelf Registration Statement expired upon the effectiveness of the 2025 Shelf Registration Statement (as defined below).

In October 2025, we filed a new shelf registration statement on Form S-3 with the SEC and an accompanying base prospectus, which was declared effective by the SEC on December 23, 2025, for the offer and sale of up to $350 million of our securities (the “2025 Shelf Registration Statement”). As of March 31, 2026, excluding the $75 million allocated to the 2025 ATM Prospectus Supplement (as defined below), $275 million of our securities remained available for offer and sale under the 2025 Shelf Registration Statement.

Sales Agreement

In December 2023, we entered into a Controlled Equity OfferingSM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co., as sales agent (“Cantor”) and filed with the SEC a prospectus supplement to the 2022 Shelf Registration Statement (the “2023 ATM Prospectus Supplement”), pursuant to which we could, at our option, offer and sell shares of our common stock, with a sales value of up to $75.0 million, from time to time, through Cantor, acting as sales agent, in transactions deemed to be “at the market offerings”, as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). Cantor was entitled to a commission of 3% of the gross proceeds from any sales of such shares. In 2024, we sold 9,000,000 shares of our common stock under the Sales Agreement and 2023 ATM Prospectus Supplement at an average price of $4.50 per share for $39.3 million in proceeds net of commissions. In 2025, we sold 23,055,402 shares of our common stock under the Sales Agreement and 2023 ATM Prospectus Supplement at an average price of $1.49 per share for $33.4 million in proceeds net of commissions. Upon the effectiveness of the 2025 Shelf Registration Statement, all offers and sales under the 2023 ATM Prospectus Supplement were deemed terminated.

In October 2025, in connection with the filing of the 2025 Shelf Registration Statement, we filed with the SEC a new prospectus supplement (the “2025 ATM Prospectus Supplement”), pursuant to which we may, at our option, offer and sell shares of our common stock, with a sales value of up to $75.0 million, from time to time, through Cantor, acting as sales agent, in transactions deemed to be “at the market offerings”, as defined in Rule 415 under the Securities Act. Cantor is entitled to a commission of 3% of the gross proceeds from any sales of such shares. The 2025 Shelf Registration Statement was declared effective by the SEC on December 23, 2025. As of March 31, 2026, $75.0 million remained available for sale under the 2025 ATM Prospectus Supplement.

Underwriting Agreements

In August 2025, we completed an underwritten public offering pursuant to an underwriting agreement (the “August Underwriting Agreement”) with Cantor, as representative of the underwriters named therein, pursuant to which we issued and sold an aggregate of 89,234,480 shares of our common stock at a price of $0.52 per share, and pre-funded warrants to purchase up to an aggregate of 21,342,442 shares of common stock at a price of $0.5199 per pre-funded warrant. The price of $0.5199 per pre-funded warrant represented the $0.52 per share purchase price for the common stock less the exercise price of $0.0001 per pre-funded warrant. The pre-funded warrants are exercisable at any time after their original issuance and will not expire. We received total net proceeds of approximately $53.5 million, after deducting underwriting discounts and commissions and offering expenses.

In November 2025, we completed an underwritten public offering pursuant to an underwriting agreement (the “November Underwriting Agreement” and together with the August Underwriting Agreement, the “Underwriting Agreements”) with Cantor, as representative of the underwriters named therein, pursuant to which we issued and sold an aggregate of 44,000,000 shares of our common stock at a price of $2.50 per share, and pre-funded warrants to purchase up to an aggregate of 6,000,000 shares of common stock at a price of $2.4999 per pre-funded warrant (the “November 2025 Underwritten Public Offering”). The price of $2.4999 per pre-funded warrant represented the $2.50 per share purchase price for the common stock less the exercise price of $0.0001 per pre-funded warrant. The pre-funded warrants are exercisable at any time after their original issuance and will not

32


 

expire. We received total net proceeds of approximately $117.2 million, after deducting underwriting discounts and commissions and offering expenses.

In December 2025, and in connection with the November 2025 Underwritten Public Offering, Cantor exercised the option pursuant to the November Underwriting Agreement to purchase 4,675,000 additional shares of common stock at the public offering price of $2.50, less underwriting discounts and commissions. In connection with such exercise, we received total net proceeds of approximately $10.9 million, after deducting underwriting discounts and commissions and offering expenses payable by us.

On April 18, 2025, we entered into a Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank, a division of First-Citizens Bank & Trust Company, as lender (the “Lender”). The Loan Agreement provides for a senior secured term loan facility in an aggregate principal amount of up to $30 million (the “Term Facility”) consisting of (a) Term A Loans in an aggregate principal amount of up to $10 million, which shall be available to be drawn from and after August 15, 2025 through December 31, 2026 upon compliance with certain financial covenants and conditions, (b) Term B Loans in an aggregate principal amount of up to $10 million, which shall be available to be drawn during the period commencing on the date of the achievement of certain net product revenue milestones and ending on June 30, 2027, and (c) Term C Loans in an aggregate principal amount of up to $10 million, which shall be available to be drawn during the period commencing on the date of the achievement of certain net product revenue milestones and ending on June 30, 2027. The proceeds of the Term Facility may be used for working capital and general business purposes. As of March 31, 2026, we had not satisfied certain financial covenants and conditions, including the net product revenue milestone required to be eligible to access proceeds from the Term Facility. Accordingly, as of March 31, 2026, no amounts have been drawn down under the Loan Agreement.

The loans under the Term Facility are due and payable on March 1, 2029 and bear interest that is payable monthly, commencing with the month in which any loans are funded under the Term Facility, in arrears at a per annum rate, subject to increase during an Event of Default (as defined in the Loan Agreement), equal to the greater of (x) the Wall Street Journal prime rate minus 0.25%, subject to a 9.00% cap, and (y) 6.00%. Commencing on April 1, 2027, which date may be extended to April 1, 2028 upon the achievement of certain net product revenue milestones (the “Interest-Only Period Extension”), we will be required to repay the principal of the Term Facility in 24 consecutive equal monthly installments or, in the case of the Interest-Only Period Extension, 12 consecutive equal monthly installments. At maturity, or if earlier prepaid, we will also be required to pay a final payment fee equal to 4.50% of the aggregate principal amount of the loans advanced under the Term Facility. The Loan Agreement provides for an unused term loan commitment fee equal to 1.00% of the Term Facility upon the earliest to occur of (a) July 1, 2027, (b) the occurrence of an Event of Default under the Loan Agreement and (c) the termination of the Loan Agreement; provided, that such fee will be waived by the Lender in the event that we have requested and the Lender has funded any loans under the Term Facility prior to such date.

Operating Activities

During the three months ended March 31, 2026, operating activities used $41.7 million of cash, primarily due to our net loss of $41.4 million and changes in our operating assets and liabilities of $3.6 million, partially offset by non-cash charges of $3.3 million. The changes in our operating assets and liabilities primarily consisted of a $11.6 million decrease in accounts payable, a $2.1 million increase in prepaid expenses and other current assets, a $1.0 million increase in other non-current assets, and a $0.3 million decrease in operating lease liabilities, partially offset by a $9.2 million increase in accrued expenses and a $2.2 million decrease in accounts receivable. The change in accounts payable and accrued expenses was primarily due to the timing of vendor invoicing and payments.

During the three months ended March 31, 2025, operating activities used $21.1 million of cash, primarily due to our net loss of $16.3 million, and changes in our operating assets and liabilities of $8.4 million, partially offset by non-cash charges of $3.6 million. The changes in our operating assets and liabilities primarily consisted of a $10.0 million decrease in accrued expenses, a $1.6 million decrease in accounts payable, and a $0.4 million decrease in operating lease liabilities, partially offset

33


 

by a $2.3 million decrease in accounts receivable and a $1.3 million decrease in prepaid expenses and other current assets. The decrease in accrued expenses was primarily due to the timing of vendor invoicing and payments.

Investing Activities

Net cash used in investing activities during the three months ended March 31, 2026 consisted of $0.7 million in purchases of property and equipment.

Net cash used in investing activities during the three months ended March 31, 2025 consisted of $0.1 million in purchases of property and equipment.

Financing Activities

Net cash used in financing activities during the three months ended March 31, 2026 consisted of $0.2 million in payments for offering costs related to the Underwriting Agreement and $0.1 million in payments for offering costs related to the Sales Agreement, partially offset by $0.1 million from the issuance of common stock under our employee stock purchase plan, and $0.1 million from exercises of stock options.

Net cash provided by financing activities during the three months ended March 31, 2025 consisted of $0.1 million from the exercises of stock options and the issuance of common stock under our employee stock purchase plan, offset by $0.1 million in payments for offering costs related to the Sales Agreement.

Funding Requirements

Our expenses are expected to increase in connection with our ongoing activities, particularly as we advance the REVOLUTION clinical program, our nonclinical and preclinical studies, and the clinical trials of our other product candidates, our ongoing and planned commercialization efforts, and any associated manufacturing activities in connection with our clinical development and commercialization activities. Our funding requirements and timing and amount of our operating expenditures will depend on many factors, including:

the revenue received from sales of PEMGARDA and any other product candidates for which we receive future regulatory authorization or approval;
the scope, progress, results and costs of discovery, nonclinical studies, preclinical development, laboratory testing and clinical trials for our product candidates and associated development programs, including our REVOLUTION clinical program;
the extent to which we develop, in-license or acquire other product candidates, intellectual property and/or technologies;
the scope, progress, results and costs of manufacturing and validation activities associated with our current product candidates with the development and manufacturing of our future product candidates as we advance them through preclinical and clinical development;
the number and development requirements of product candidates that we may pursue;
the costs, timing and outcome of regulatory review of our product candidates;
our headcount growth and associated costs as we expand our research and development capabilities and build and maintain a commercial infrastructure for product candidates for which we obtain regulatory authorization or approval;
the timing and costs of securing sufficient manufacturing capacity for clinical and commercial supply of our product candidates, or the raw material components thereof;
the costs and timing of commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive regulatory authorization or approval;
the costs necessary to obtain regulatory authorizations or approvals, and the costs of post-marketing studies that could be required by regulatory authorities in jurisdictions where authorization or approval is obtained;
the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims;
the continuation of our existing licensing and collaboration arrangements and entry into new collaborations and licensing arrangements, if at all;
the costs we incur in maintaining business operations;

34


 

the need to implement additional internal systems and infrastructure;
the effect of competing technological, product and market developments;
the costs of operating as a public company; and
the impact of any business interruptions to our operations or to those of our third-party contractors resulting from any public health crisis.

Substantial Doubt about Ability to Continue as a Going Concern

In accordance with Accounting Standards Update 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), we are required to evaluate whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern from the issuance date of our condensed consolidated financial statements. Based on current operating plans and excluding future external financing, we will not have sufficient cash and cash equivalents to fund our operating expenses and capital requirements beyond one year from the issuance of these condensed consolidated financial statements, and therefore, we have concluded that there is substantial doubt about our ability to continue as a going concern. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect.

We expect to finance our operations through a combination of contribution from revenues, equity offerings, government or private-party grants, debt financings or other capital sources, such as collaborations with other companies, strategic alliances or licensing arrangements to support our continuing operations and pursue our growth strategy. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our stockholders’ ownership interest will be diluted, and the terms of such securities may include liquidation or other preferences and anti-dilution protections that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. Such restrictions could adversely impact our ability to conduct our operations and execute our business plan. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs, or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to secure additional funds through contribution from revenues, equity or debt financings or through other sources, when needed, we may be required to delay, limit, reduce or terminate our product development programs or any commercialization efforts or grant rights to develop and market product candidates to third parties that we would otherwise prefer to develop and market ourselves.

Contractual Obligations and Commitments

We lease certain office and laboratory space classified as operating leases. See Note 9 of our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for further detail on our lease obligations and the timing of expected future payments.

In addition, we enter into agreements with third parties in the ordinary course of business for various products and services, including those related to research, preclinical and clinical operations, manufacturing and support, supply chain, and distribution. These contracts do not contain any material minimum purchase commitments. Certain of these agreements provide for termination rights subject to the payment of termination fees and/or wind-down costs. Under such agreements, we are contractually obligated to make certain payments to vendors upon early termination, primarily to reimburse them for their unrecoverable outlays incurred prior to cancellation as well as any amounts owed by us prior to early termination. The actual amounts we could pay in the future to the vendors under such agreements may differ from the purchase order amounts due to cancellation provisions. The termination fees were not probable of payment as of March 31, 2026.

Critical Accounting Policies and Significant Judgments and Estimates

Our financial statements are prepared in accordance with generally accepted accounting principles in the U.S. The preparation of our financial statements and related disclosures requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. Our critical accounting policies and estimates are described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Significant Judgments and Estimates” in the 2025 Form 10-K. If actual results or events differ materially from the estimates, judgments and assumptions used by us in applying these policies, our reported financial condition and results of operations could be materially affected. There have been no significant changes to our critical accounting policies and estimates from those described in the 2025 Form 10-K.

Recently Issued Accounting Pronouncements

A description of recently issued accounting pronouncements that may potentially impact our financial position, results of operations and cash flows is disclosed in Note 2 to our condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

Emerging Growth Company Status

We are an “emerging growth company,” as defined in the JOBS Act, and will remain an emerging growth company until December 31, 2026. For so long as we remain an emerging growth company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include:

an exemption from compliance with the auditor attestation requirement in the assessment of our internal control over financial reporting;
reduced disclosure obligations regarding executive compensation;
exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved; and
an exemption from compliance with the requirements of the Public Company Accounting Oversight Board regarding the communication of critical audit matters in the auditor’s report on the financial statements.

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of these accounting standards until they would otherwise apply to private companies.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information required under this item.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Financial Officer (our principal executive officer and principal financial officer), evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2026. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as amended, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on the evaluation of our disclosure controls and procedures as of March 31, 2026, our Chief Financial Officer concluded that our disclosure controls and procedures as of such date were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fiscal quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

37


 

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may become involved in legal proceedings or other litigation relating to claims arising in the ordinary course of business. We accrue liability for such matters when it is probable that future expenditures will be made and that such expenditures can be reasonably estimated. Significant judgment is required to determine both probability and estimated exposure amount. Legal fees and other costs associated with such proceedings are expensed as incurred. As of March 31, 2026, we were not a party to any material legal proceedings.

Item 1A. Risk Factors.

Information regarding risks and uncertainties related to our business appears in Part I, Item 1A. “Risk Factors” of the 2025 Form 10-K. As of the date of this Quarterly Report on Form 10-Q, there have been no material changes from the risk factors set forth in the 2025 Form 10-K.

Recent Sales of Unregistered Securities; Use of Proceeds

We did not issue any unregistered equity securities during the three months ended March 31, 2026.

Purchases of Equity Securities by the Issuer
