(unaudited)
(amounts in thousands, except per share data)
1. Nature of the Business and Basis of Presentation
Enanta Pharmaceuticals, Inc. (collectively with its subsidiary, the “Company”), incorporated in Delaware in
The Company is subject to many of the risks common to companies in the biotechnology industry, including but not limited to, the uncertainties of research and development, competition from technological innovations of others, dependence on collaborative arrangements, protection of proprietary technology, dependence on key personnel and compliance with government regulation. Product candidates currently under development will require significant additional research and development efforts, including extensive preclinical and clinical testing and regulatory approvals, prior to commercialization. These efforts require significant amounts of capital, adequate personnel and infrastructure, and extensive compliance reporting capabilities.
Unaudited Interim Financial Information
The condensed consolidated balance sheet as of September 30, 2025 was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). The accompanying unaudited condensed consolidated financial statements as of June 30, 2026 and for the three and nine months ended June 30, 2026 and 2025 have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2025.
In the opinion of management, all adjustments, consisting of normal recurring adjustments necessary for a fair statement of the Company’s financial position as of June 30, 2026 and results of operations for the three and nine months ended June 30, 2026 and 2025 and cash flows for the nine months ended June 30, 2026 and 2025 have been made. The results of operations for the three and nine months ended June 30, 2026 are not necessarily indicative of the results of operations that may be expected for subsequent quarters or the year ending September 30, 2026.
The accompanying condensed consolidated financial statements have been prepared in conformity with GAAP. All amounts in the condensed consolidated financial statements and in the notes to the condensed consolidated financial statements, except per share amounts, are in thousands unless otherwise indicated.
The accompanying condensed consolidated financial statements have been prepared based on continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business.

2. Summary of Significant Accounting Policies
For the Company’s Significant Accounting Policies, please refer to its Annual Report on Form 10-K for the fiscal year ended September 30, 2025. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). There have been no material changes to the Company’s significant accounting policies since the beginning of this fiscal year.
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with 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 period. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, management’s judgments with respect to its revenue arrangements; liability related to the sale of future royalties; valuation of stock-based awards and the accrual of research and development expenses. Estimates are periodically reviewed in light of changes in circumstances, facts and experience.
Net Loss per Share
Basic net loss per common share is computed by dividing the net loss by the weighted average number of shares of common stock outstanding for the period. In periods in which the Company has reported a net loss, diluted net loss per common share is the same as basic net loss per common share since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.

Recently Issued Accounting Pronouncements
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) (“ASU 2023-09”), which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for the Company in the fiscal year beginning October 1, 2025, with early adoption permitted. The Company does not expect ASU 2023-09 to have a material impact on the Company’s consolidated financial statements and related disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”), which requires public entities to provide disaggregated disclosure of income statement expenses. Public entities are required to disaggregate, in a tabular presentation, each relevant expense caption on the face of the consolidated statements of operations such as the following expenses: purchases of inventory, employee compensation, intangible asset amortization, and depreciation. ASU 2024-03 is effective for the Company in the fiscal year beginning October 1, 2027, with early adoption permitted. The Company is currently evaluating the potential impact that ASU 2024-03 may have on its financial statement disclosures.

6. AbbVie Collaboration
The Company has a Collaborative Development and License Agreement (as amended, the “AbbVie Agreement”) with AbbVie to identify, develop and commercialize HCV NS3 and NS3/4A protease inhibitor compounds, including paritaprevir and glecaprevir, under which the Company has received license payments, proceeds from a sale of preferred stock, research funding payments, milestone payments and royalties totaling approximately $

7. Liability Related to the Sale of Future Royalties
In April 2023, the Company entered into a royalty sale agreement with an affiliate of OMERS, pursuant to which the Company was paid a $
Because the royalty sale agreement will be paid back to OMERS up to a capped amount, as well as the Company’s significant continuing involvement in the generation of future cash flows under its AbbVie Agreement, the Company recorded the proceeds from the transaction as a liability on its condensed consolidated balance sheets which will be amortized as interest expense in the condensed consolidated statements of operations under the effective interest rate method over the life of the royalty sale agreement. The Company will continue to record the full amount of royalties earned on MAVYRET/MAVIRET sales as royalty revenue in its condensed consolidated statements of operations.
The Company’s liability related to the sale of future royalties is estimated based on forecasted worldwide MAVYRET/MAVIRET royalties to be paid to OMERS over the course of the royalty sale agreement. This estimate requires significant judgment, including the amount and timing of royalty payments up until the end of the royalty sale agreement, which is estimated to be the stated term of June 30, 2032. As royalties are earned by OMERS, the liability is reduced on the Company’s condensed consolidated balance sheets.
At June 30, 2026, the estimated future cash flows resulted in an effective annual imputed interest rate of approximately

With respect to some of these patents, the Company expects that it will be required to obtain licenses and could be required to pay license fees or royalties, or both. These licenses may not be available on acceptable terms, or at all. A costly license, or inability to obtain a necessary license, would have a material adverse effect on the Company’s financial condition, results of operations or cash flows. The Company accrues contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated.
In June 2022, the Company filed suit in the United States District Court for the District of Massachusetts against Pfizer Inc. seeking damages for infringement of U.S. Patent No. 11,358,953 (the “’953 Patent”) in the manufacture, use, and sale of Pfizer’s COVID-19 antiviral, Paxlovid™ (nirmatrelvir tablets; ritonavir tablets). The United States Patent and Trademark Office awarded the ’953 Patent to the Company in June 2022 based on the Company's July 2020 patent application describing coronavirus protease inhibitors invented by the Company. In December 2024, the District Court issued a summary judgment decision ruling that the asserted claims of the ’953 Patent were invalid. The Company filed a notice of appeal with the United States Court of Appeals for the Federal Circuit, and, in June 2026, the Federal Circuit affirmed the decision of the District Court and ruled that the claims of the ’953 Patent were invalid. On July 23, 2026, the Company filed a combined petition for panel or en banc rehearing of the Federal Circuit’s decision. The timing for a decision on the petition remains uncertain; however, the Company anticipates a decision from the Federal Circuit before the end of September 2026.
In August 2025, the Company filed a patent infringement action in the Unified Patent Court (the “UPC”) of the European Union against Pfizer Inc. and certain of its subsidiaries. The suit seeks a determination of liability for infringement of European Patent No. EP 4 051 265 (the “’265 Patent”) in connection with Pfizer’s manufacture, use, and sale of Paxlovid™ (nirmatrelvir tablets; ritonavir tablets) in the 18 EU member states participating in the UPC. The ’265 Patent is the European counterpart to the ’953 Patent. A hearing on the infringement action and counterclaim for revocation has been scheduled for September 29, 2026 and, under the UPC procedures, a decision is expected to be rendered within weeks thereafter. If the UPC determines there has been infringement, subsequent proceedings would be required to determine damages. In May 2026, Pfizer also filed an opposition against the ’265 Patent with the European Patent Office (the “EPO”). All timelines remain subject to potential rights of appeal and other customary proceedings in European patent litigation and EPO procedures.
The Company records all legal expenses associated with the patent infringement suits as incurred in the consolidated statements of operations.
Indemnification Agreements
In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to customers, vendors, lessors, 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 services to be provided to the Company, 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 will 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 officers. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many cases, unlimited. To date, the Company has not incurred any material costs as a result of such indemnifications. In addition, the Company maintains directors’ and officers’ insurance coverage. The Company does not believe that the outcome of any claims under indemnification arrangements will have a material effect on its financial
15
position, results of operations or cash flows, and has not accrued any liabilities related to such obligations in its condensed consolidated financial statements as of June 30, 2026.
11. Segment Information
The Company manages its operations as a operating segment for the purpose of assessing performance and making operating decisions. The Company’s singular focus is on discovering and developing small molecule drugs with an emphasis on virology and immunology indications. The Company’s Chief Operating Decision Maker (“CODM”) is the Company’s (“CEO”).

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto included elsewhere in this Quarterly Report on Form 10-Q, or Form 10-Q, and the audited consolidated financial statements and notes thereto for our fiscal year ended September 30, 2025 included in our Annual Report on Form 10-K for that fiscal year, which is referred to as our 2025 Form 10-K. Please refer to our note regarding forward-looking statements on page 2 of this Form 10-Q, which is incorporated herein by this reference.
The Enanta name and logo are our trademarks. This Form 10-Q also includes trademarks, trade names and service marks of other persons. All other trademarks, trade names and service marks appearing in this Form 10-Q are the property of their respective owners.
Overview
We are a biotechnology company that uses our robust, chemistry-driven approach and drug discovery capabilities to discover and develop small molecule drugs for virology and immunology indications.
Virology:
We discovered glecaprevir, the second of two antiviral protease inhibitors developed through our collaboration with AbbVie for the treatment of acute or chronic infection with hepatitis C virus, or HCV. Glecaprevir is co-formulated as part of AbbVie’s leading brand of direct-acting antiviral, combination treatment for HCV, which has been marketed under the tradenames MAVYRET® (U.S.) and MAVIRET® (ex-U.S.) (glecaprevir/pibrentasvir) since 2017 for the treatment of chronic HCV. MAVYRET and MAVIRET were also approved as the first and only treatments for acute HCV infection in the United States and the European Union in June 2025 and June 2026, respectively.
Our active development programs in virology are focused on respiratory syncytial virus, or RSV, the most common cause of bronchiolitis and pneumonia and a leading cause of U.S. hospitalization in young children, and a significant cause of respiratory illness in older adults. Populations at high risk for severe RSV infection include infants and young children, adults older than 65 years of age, and those with comorbidities such as chronic heart or lung disease. CDC estimates from the United States 2024-2025 RSV season indicate that RSV led to up to 6.8 million outpatient visits, approximately 370,000 hospitalizations, and up to 24,000 deaths. We estimate a global market opportunity of over $2 billion for an oral RSV antiviral for children and all high-risk adults, with a potential total addressable population of greater than 3 million patients in the United States. Additionally, we believe that the recent FDA approval of at-home combination self-tests capable of detecting RSV, influenza A & B, and COVID-19 will further drive RSV diagnosis and potentially enable a test-to-treat model for zelicapavir.
We also have clinical-stage programs in virology for SARS-CoV-2, the virus that causes COVID-19, and Hepatitis B virus, or HBV, the most prevalent chronic hepatitis.
Immunology:
In immunology, we are designing and developing highly potent and selective, oral small molecule inhibitors for the treatment of type 2 inflammatory disease by targeting key mechanisms of the immune response. An overactive immune response is a primary driver of a number of inflammatory diseases for which there is an enduring unmet need including atopic dermatitis, or AD, urticaria, asthma, prurigo nodularis, or PN, chronic rhinosinusitis with nasal polyps, or CRSwNP, as well as some forms of chronic obstructive pulmonary disease, or COPD, eosinophilic esophagitis, or EoE, allergic rhinoconjunctivitis, or ARC, and other conditions. Based on industry reports, by 2032 the market is projected to be approximately $40 billion for urticaria and AD, approximately $40 billion for the combined market of asthma, COPD, CRSwNP, EoE, ARC and PN and could include an additional $40 billion or greater taking into account potential expansion into gastrointestinal and neurology indications thought to be associated with mast cells.
Our initial immunology targets involve the following mechanisms:
17
These mechanisms are implicated, along with others, in several diseases, and it is not uncommon for an efficacious treatment for one disease to be tested and approved for other immunology indications. In addition, these mechanisms are orthogonal approaches that may provide additive or complementary benefit if used in combination. We currently plan to focus our initial immunology drug development, proof-of-concept efforts on the following disease indications:
As of June 30, 2026, we had $211.5 million in cash, cash equivalents and short-term and long-term marketable securities. Based on our operating plan, we believe that our existing cash, cash equivalents and short-term and long-term marketable securities as of June 30, 2026, as well as the cash flows from our retained portion of future HCV royalties, will enable us to fund our operating expenses and capital expenditure requirements into fiscal 2029.
Our Wholly-Owned Programs
All of our development programs are wholly-owned, including our RSV and immunology programs.
RSV. We have two clinical stage candidates for RSV – zelicapavir (EDP-938) and EDP-323, both of which have Fast Track designation from the U.S. Food and Drug Administration, or FDA. Both candidates inhibit viral replication and the production of new virions for both major subgroups of RSV, and differ from fusion inhibitors, which act only at viral entry. Zelicapavir is an inhibitor of the RSV N-protein, and EDP-323 is an inhibitor of the RSV L-protein.
In these Phase 2 clinical studies, zelicapavir has demonstrated a favorable safety profile, consistent with that observed in over 700 subjects exposed to zelicapavir to date, as well as antiviral activity and reductions in symptom duration.
18
Immunology. We are leveraging our expertise in developing small molecule inhibitors to design and develop highly potent and selective oral medicines targeting the following mechanisms of immune response:
We have utilized our internal chemistry and drug discovery capabilities to generate all of our development-stage programs. We continue to invest substantial resources in research programs to discover compounds targeting new disease areas.
The following table summarizes our product development pipeline in our virology and immunology programs:

Our Royalty Revenue Collaboration and Royalty Sale Agreement
Our royalty revenue is generated through our Collaborative Development and License Agreement with AbbVie, under which we have discovered and out-licensed to AbbVie two protease inhibitor compounds that have been clinically tested, manufactured, and commercialized by AbbVie as part of its combination regimens for HCV.
Glecaprevir is the HCV protease inhibitor we discovered that was developed by AbbVie in a fixed-dose combination with its NS5A inhibitor, pibrentasvir, for the treatment of chronic HCV. This product was also approved by the FDA and European Commission as the first and only treatment for acute HCV infection in June 2025 and June 2026, respectively. This patented combination, currently marketed under the brand names MAVYRET® (U.S.) and MAVIRET® (ex-U.S.), is referred to in this report as MAVYRET/MAVIRET. The first protease inhibitor developed through this collaboration, paritaprevir, is part of AbbVie’s initial HCV regimens, which have been almost entirely replaced by MAVYRET/MAVIRET. Since August 2017, substantially all of our royalty revenue has been derived from AbbVie’s net sales of MAVYRET/MAVIRET. Our ongoing royalty revenues from this regimen consist of annually tiered, double-digit, per-product royalties on 50% of the calendar year net sales of the glecaprevir/pibrentasvir combination in MAVYRET/MAVIRET. The annual royalty tiers return to the lowest tier for sales on and after each January 1.
In April 2023, we entered into a royalty sale agreement with an affiliate of OMERS, a Canadian public employee pension fund, pursuant to which we were paid a $200.0 million cash purchase price in exchange for 54.5% of our future quarterly royalty payments on net sales of MAVYRET/MAVIRET, after June 30, 2023, through June 30, 2032, subject to a cap on aggregate payments to OMERS equal to 1.42 times the purchase price.
For accounting purposes, we continue to record 100% of HCV royalties earned under the AbbVie agreement as royalty revenue in our consolidated statements of operations. The $200.0 million received in April 2023 was recognized on our condensed consolidated balance sheets as a liability, which will be reduced by the payments made to OMERS over the term of the Agreement. We recognize imputed interest expense over the life of the royalty sale agreement based on our estimated future MAVYRET/MAVIRET royalties.
Financial Operations Overview
We are currently funding all research and development for our wholly-owned programs, which are targeted toward the discovery and development of novel compounds. We are advancing zelicapavir into the RESOLVE study, a registrational Phase 2b/3 clinical trial in adults at high risk of severe outcomes from RSV infection. In addition, we are conducting the LOTUS study, a Phase 2b clinical trial of zelicapavir in pediatric patients with RSV, and a Phase 1 clinical trial of EDP-978, our lead immunology program. We are also continuing to conduct preclinical discovery research efforts in immunology.
20
As a result of the timing of our clinical and preclinical development programs, we expect our research and development expenses will fluctuate from period to period. In the next 12 months, we expect an increase in our external research and development expenses, primarily driven by the timing of clinical trials in our RSV programs.
To date, we have funded our operations primarily through royalty payments received under our collaboration agreement with AbbVie, a $200.0 million payment received in April 2023 from our royalty sale agreement and our existing cash, cash equivalents and short-term and long-term marketable securities. Based on our operating plan, we believe that our existing cash, cash equivalents and short-term and long-term marketable securities, as well as the cash flows from our retained portion of future HCV royalties, will enable us to fund our operating expenses and capital expenditure requirements into fiscal 2029.
Revenue
Our revenue is primarily derived from our collaboration agreement with AbbVie and AbbVie’s sales of MAVYRET/MAVIRET, an 8-week treatment regimen for acute or chronic HCV.
The following table is a summary of revenue recognized for the three and nine months ended June 30, 2026 and 2025:

As disclosed above regarding our OMERS royalty sale agreement, we only retain 45.5% of the cash payments from royalties on net sales of MAVYRET/MAVIRET occurring after June 30, 2023 through June 30, 2032, subject to a cap on aggregate payments to OMERS equal to 1.42 times OMERS’ purchase price.
Internal Programs
As our internal product candidates are currently in preclinical or clinical development, we have not generated any revenue from our own product sales. We do not expect to generate any revenue from product sales derived from these product candidates for at least the next several years.
Operating Expenses
Our operating expenses are comprised of research and development expenses and general and administrative expenses.
Research and Development Expenses
Research and development expenses consist of costs incurred to conduct basic research, such as the discovery and development of novel small molecules as therapeutics, as well as any external expenses of preclinical and clinical development activities. We expense all costs of research and development as incurred. These expenses consist primarily of:
At any given time, we have later stage programs in clinical development as well as several active early-stage research and drug discovery projects. Our internal resources, employees and infrastructure are utilized across multiple projects, including our early-stage discovery projects. As such, we report information regarding costs incurred based on our programs (i.e., disease area) rather than on a project specific basis. All indirect costs are allocated to programs based on headcount and square footage of our facilities. We expect that our research and development expenses will fluctuate from period to period as we advance our research and development programs. However, in the next 12 months, we expect an increase in our external research and development expenses, primarily driven by the timing of clinical trials in our RSV programs. To date, we have not identified any significant impact of inflation on spending in research and development, but it is uncertain whether there will be inflationary impacts in future periods.
21
Our research and drug discovery and development programs are in early stages; therefore, the successful development of our product candidates is highly uncertain and may not result in approved products. Completion dates and completion costs can vary significantly for each product candidate and are difficult to predict. Given the uncertainty associated with clinical trial enrollments and the risks inherent in the development process, we are unable to determine the duration and completion costs of the current or future clinical trials of our product candidates or if, or to what extent, we will generate revenue from the commercialization and sale of any of our product candidates. We anticipate that we will make determinations as to which development programs to pursue and how much funding to direct to each program on an ongoing basis in response to the preclinical and clinical success and prospects of each product candidate, as well as ongoing assessments of the commercial potential of each product candidate.
General and Administrative Expenses
General and administrative expenses consist primarily of personnel costs, which include salaries, related benefits and stock-based compensation, of our executive, finance, business and corporate development and other administrative functions. General and administrative expenses also include allocated facility-related costs not otherwise included in research and development expenses, directors’ and officers’ liability insurance premiums, professional fees for auditing, tax, and legal services, patent expenses and litigation expenses associated with prosecuting our patent infringement litigation.
We expect that general and administrative expenses may increase in the long term. To date we have not experienced a significant impact of inflation on general and administrative expenses.
Other Income (Expense)
Other income (expense) consists of interest expense, interest and investment income, net and the change in fair value of our outstanding Series 1 nonconvertible preferred stock. Interest expense consists of the interest expense and amortization of debt issuance costs associated with the royalty sale agreement with an affiliate of OMERS. Interest income consists of interest earned on our cash equivalents and marketable securities balances. Investment income consists of the amortization or accretion of any purchased premium or discount, respectively, on our marketable securities. The change in fair value of our Series 1 nonconvertible preferred stock relates to the remeasurement of these financial instruments from period to period as these instruments may require a transfer of assets because of the liquidation preference features of the underlying instrument.
Income Tax (Expense) Benefit
Income tax (expense) benefit is based on our best estimate of taxable net income (loss), applicable income tax rates, net research and development tax credits and carryforwards, net operating loss carrybacks and interest earned on such refunds, changes in valuation allowance estimates and deferred income taxes.

Revenue
We recognized revenue of $14.4 million during the three months ended June 30, 2026 as compared to $18.3 million during the three months ended June 30, 2025. The $4.0 million decrease in revenue was primarily due to AbbVie’s lower reported HCV sales as compared to the same period in 2025.
Our royalty revenues eligible to be earned in the future will depend on AbbVie’s HCV market share, the pricing of the MAVYRET/MAVIRET regimen, the number of patients treated and the effect of the label expansion for MAVYRET/MAVIRET for the treatment of patients with acute HCV infection. In addition, at the beginning of each calendar year (the second quarter of our fiscal year), our royalty rate resets to the lowest tier for each of our royalty-bearing products licensed to AbbVie.
Beginning with the three months ended September 30, 2023, 54.5% of our quarterly royalty payments on net sales of MAVYRET/MAVIRET that are included in our total revenue are paid to OMERS through June 30, 2032, subject to a cap on aggregate payments equal to 1.42 times the purchase price. The $200.0 million received in April 2023 was recognized on our
22
condensed consolidated balance sheets as a liability which will be reduced by the payments made to OMERS over the term of the royalty sale agreement. We will continue to record 100% of HCV royalties earned under the AbbVie Agreement as royalty revenue in our condensed consolidated statements of operations since the AbbVie Agreement has not been amended and is independent of our agreement with OMERS.

Research and development expenses for the three months ended June 30, 2026 decreased by $5.1 million compared to the same period in 2025.
Virology
The costs in our virology programs decreased by $9.5 million due to the timing of clinical trials in our RSV programs.
Immunology
The costs in our immunology programs increased by $3.7 million due to scale-up and IND-enabling activities for such programs.
Other Programs
Other program costs increased by $0.8 million as we advanced early-stage drug discovery efforts.
General and administrative expenses
General and administrative expenses decreased by $0.5 million for the three months ended June 30, 2026 compared to the same period in 2025. The decrease was primarily due to lower stock-based compensation expenses during the three months ended June 30, 2026.
Other income (expense)
Changes in components of other income (expense) were as follows:
Interest expense
Interest expense increased by $2.5 million for the three months ended June 30, 2026, as compared to the same period in 2025, due to an increase in forecasted royalties arising from AbbVie’s product sales under the AbbVie Agreement and corresponding royalty payment to OMERS arising from such sales pursuant to our OMERS royalty sales agreement.
Interest and investment income, net
Interest and investment income, net, decreased by $0.4 million for the three months ended June 30, 2026, as compared to the same period in 2025. The decrease was due to lower interest rates year over year.
Income tax expense
The income tax expense of less than $0.1 million during the three months ended June 30, 2026 and 2025 was primarily due to state income taxes.
23
On July 4, 2025, the U.S. government enacted the One Big Beautiful Bill Act, which includes several changes to U.S. federal income tax law, including the temporary and permanent extension of expiring provisions of the Tax Cuts and Jobs Act of 2017, such as 100% bonus depreciation and immediate expensing of domestic research and development costs. The new legislation has multiple effective dates, with certain provisions effective in 2025 and others in the future. We determined that the legislation does not have a material impact on our condensed consolidated financial statements for the three and nine months ended June 30, 2026.

Revenue
We recognized revenue of $50.1 million during the nine months ended June 30, 2026 as compared to $50.2 million during the nine months ended June 30, 2025. The $0.1 million decrease in revenue was primarily due to a slight decrease in AbbVie’s reported HCV sales as compared to the same period in 2025.

Research and development expenses for the nine months ended June 30, 2026 decreased by $20.5 million compared to the same period in 2025.
Virology
The costs in our virology program decreased by $35.9 million due to the timing of our clinical trials in our RSV program.
Immunology
The costs in our immunology programs increased by $12.2 million due to scale-up and IND-enabling activities for such programs.
Other Programs
Other program costs increased by $3.2 million as we advanced early-stage drug discovery efforts.
General and administrative expenses
General and administrative expenses decreased by $6.2 million for the nine months ended June 30, 2026 compared to the same period in 2025. The decrease was primarily due to lower stock-based compensation expenses during the nine months ended June 30, 2026 and a decrease in legal expenses related to our patent infringement suit against Pfizer for the ’953 Patent.
Other income (expense)
Changes in components of other income (expense) were as follows:
Interest expense
Interest expense increased by $5.2 million for the nine months ended June 30, 2026, as compared to the same period in 2025 due to an increase in forecasted royalties arising from AbbVie’s product sales under the AbbVie Agreement and corresponding royalty payment to OMERS arising from such sales pursuant to our OMERS royalty sales agreement.
Interest and investment income, net
Interest and investment income, net, decreased by $1.0 million for the nine months ended June 30, 2026, as compared to the same period in 2025. The decrease was due to lower interest rates year over year.
Income tax (expense) benefit
The income tax expense of $0.1 million during the nine months ended June 30, 2026 was primarily due to state income taxes. The income tax benefit of $1.7 million during the nine months ended June 30, 2025 was primarily due to an additional federal income tax refund from a net operating loss carryback of $0.9 million. We received the federal income tax refund of $33.8 million, inclusive of interest, in April 2025.
Liquidity and Capital Resources
We fund our operations with cash flows from our retained portion of our royalty revenue and our existing financial resources. At June 30, 2026, our principal sources of liquidity were cash and cash equivalents and short-term and long-term marketable securities of $211.5 million.
On July 2, 2026, we entered into an Open Market Sale AgreementSM with Jefferies LLC, as sales agent, under which we may offer and sell shares of our common stock, having an aggregate offering price of up to $75.0 million, from time to time through Jefferies under the at-the-market (ATM) facility. We have not issued any shares of common stock under this sale agreement through the filing date of this Form 10-Q.
The following table shows a summary of our cash flows:

Net cash used in operating activities
Cash used in operating activities was $28.8 million for the nine months ended June 30, 2026 as compared to cash used in operating activities of $12.8 million for the same period in 2025. Our cash used in operating activities was lower in 2025 primarily due to receipt of a $33.8 million income tax refund in April 2025, partially offset by lower research and development payments in 2026.
Net cash (used in) provided by investing activities
Cash used in investing activities was $21.4 million for the nine months ended June 30, 2026 as compared to cash provided by investing activities of $38.1 million for the same period in 2025. Our cash used in investing activities increased by $59.4 million, driven by the timing of purchases and maturities of marketable securities in 2026 compared to 2025.
Net cash provided by (used in) financing activities
Cash provided by financing activities was $51.3 million for the nine months ended June 30, 2026 as compared to cash used in financing activities of $18.3 million for the same period in 2025. Our cash provided by financing activities increased by $69.6 million, driven primarily by proceeds received from our public offering which closed in October 2025.
Funding Requirements
As of June 30, 2026, we had $211.5 million in cash, cash equivalents and short-term and long-term marketable securities. Based on our operating plan, we believe that our existing cash, cash equivalents and short-term and long-term marketable securities as of June 30, 2026, as well as the cash flows from our retained portion of future HCV royalties, will enable us to fund our operating expenses and capital expenditure requirements into fiscal 2029. However, our projection of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially.
Our future capital requirements are difficult to forecast and will depend on many factors, including:
26
Off-Balance Sheet Arrangements
We do not engage in any off-balance sheet financing activities. We do not have any interest in entities referred to as variable interest entities, which include special purpose entities and other structured finance entities.
Contractual Obligations and Commitments
Facility Leases
As of the date of this report, we lease space in Watertown, Massachusetts, under two separate lease agreements with one landlord.
In May 2022, we entered into a ten-year lease for new laboratory and office space in Watertown, Massachusetts, adjacent to our 400 Talcott Avenue premises at Arsenal on the Charles at 4 Kingsbury Avenue since our lease for office and laboratory space at 500 Arsenal Street was to expire on September 1, 2027. The construction of the facility shell was completed and we gained access to the building to construct tenant improvements during the three months ended March 31, 2024. Upon gaining access to the 4 Kingsbury Avenue building, we capitalized a right-of-use asset and lease liability of approximately $32 million on our consolidated balance sheets which reflects our fixed base rent payments, net of approximately $15 million of a tenant improvement allowance provided by the landlord, over the 10-year term of the lease. The 4 Kingsbury Avenue lease ends on September 30, 2034.
In conjunction with the commencement of our lease at 4 Kingsbury Avenue, during the three months ended March 31, 2024, we adjusted our 500 Arsenal Street lease liability to shorten the expiration date from September 2027 to the date the 4 Kingsbury Avenue building became ready for our occupancy. This resulted in a decrease in the lease liability and right-of-use asset on our consolidated balance sheets by approximately $9.0 million. The rent commencement date for our 4 Kingsbury Avenue lease was September 12, 2024, and we moved into the space in November 2024, at which time our lease at 500 Arsenal Street expired.
The second lease for office space located at 400 Talcott Avenue commenced on September 24, 2018 for a term of six years. In May 2022, we amended this lease to expand the rented space and extend the lease term through June 1, 2034. We spent approximately $6.3 million in capital expenditures for the additional space, which primarily relate to tenant improvements. We received a tenant improvement allowance from the landlord of $2.5 million. In July 2024, we amended our lease agreement to confirm alignment with the lease end date of our 4 Kingsbury Avenue lease at September 30, 2034.
Total estimated minimum lease payments for the next 5 years and thereafter under our existing facility and leased equipment agreements are $2.1 million for the remainder of 2026, $8.7 million in 2027, $9.0 million in 2028, $9.3 million in 2029, $9.5 million in 2030, and $41.1 million thereafter.
OMERS Agreement
In April 2023, we entered into a royalty sale agreement with an affiliate of OMERS, pursuant to which we were paid a $200.0 million cash purchase price in exchange for 54.5% of our future quarterly royalty payments on net sales of MAVYRET/MAVIRET after June 30, 2023, through June 30, 2032, subject to a cap on aggregate payments equal to 1.42 times the purchase price.
The $200.0 million received in April 2023 was recognized on our condensed consolidated balance sheets as a liability which will be reduced by the payments made to OMERS over the term of the Agreement.
Preferred Stock
As of June 30, 2026, we had 1.9 million outstanding shares of Series 1 nonconvertible preferred stock, all of which we classified as a long-term liability on our consolidated balance sheet and recorded at fair value of $1.3 million. The fair value of the preferred stock was measured based on significant inputs not observable in the market, which represented a Level 3 measurement within the fair value hierarchy. The fair value of these instruments represents less than 10% of liabilities as of June 30, 2026. The Series 1 nonconvertible preferred stock issued would require the payment of $2.0 million in the event of a qualifying merger or sale of the company.
Critical Accounting Policies
Our condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of our condensed consolidated financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amount of assets, liabilities, revenue, costs and expenses, and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions and conditions. See our 2025 Form 10-K for information about our critical accounting policies as well as a description of our other significant accounting policies. There have been no material changes to our critical accounting policies since the beginning of this fiscal year.
