    NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

    (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 1995, is a biotechnology company that uses its robust, chemistry-driven approach and drug discovery capabilities to discover and develop small molecule drugs with an emphasis on virology and immunology indications. The Company discovered glecaprevir, the second of two antiviral protease inhibitors discovered and developed through its collaboration with AbbVie for the treatment of chronic infection with hepatitis C virus, or HCV. Glecaprevir is co-formulated as part of AbbVie’s leading brand of direct-acting antiviral, or DAA, combination treatment for HCV, which has been marketed under the tradenames MAVYRET® (U.S.) and MAVIRET® (ex-U.S.) (glecaprevir/pibrentasvir) since 2017.

    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.

The accompanying unaudited condensed consolidated financial statements as of December 31, 2024 and for the three months ended December 31, 2024 and 2023 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, 2024.

    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 December 31, 2024 and results of operations for the three months ended December 31, 2024 and 2023 and cash flows for the three months ended December 31, 2024 and 2023 have been made. The results of operations for the three months ended December 31, 2024 are not necessarily indicative of the results of operations that may be expected for subsequent quarters or the year ending September 30, 2025.

    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. The Company began reporting a net loss in fiscal 2020 and reported a net loss of $22,290 for the three months ended December 31, 2024 and $116,045 for the year ended September 30, 2024. As of December 31, 2024, the Company had an accumulated deficit of $345,330. The Company expects to continue to generate operating losses for the foreseeable future as the Company continues to advance its wholly-owned programs. As of December 31, 2024, the Company had $216,691 in cash, cash equivalents and short-term marketable securities. The Company expects that its cash, cash equivalents and short-term marketable securities will be sufficient to fund its operating expenses and capital expenditure requirements for at least 12 months from the issuance date of the interim condensed consolidated financial statements. The Company may seek additional funding through equity offerings, non-dilutive financings, collaborations, strategic alliances or licensing agreements. The Company may not be able to obtain sufficient 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 the rights of the Company’s stockholders. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate some or all of its research and development programs, product expansion or commercialization efforts, or the Company may be unable to continue operations.

    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, 2024. 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”).

    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. Therefore, the Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss as its effect would have been anti-dilutive:

    Recently Issued Accounting Pronouncements

    In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) ("ASU 2023-07"), which requires public entities to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment disclosures and reconciliation requirements in ASC 280 on an interim and annual basis. This amendment is effective for the Company in the fiscal year beginning October 1, 2024, and interim periods within the fiscal year beginning October 1, 2025, on a retrospective basis with early adoption permitted. This accounting standard will require additional disclosures about segment information, however, the Company does not expect ASU 2023-07 to have a material impact on the Company’s consolidated financial position or results of operations.

    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 is currently evaluating the potential impact that ASU 2023-09 may have on its financial statement 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.

    During the three months ended December 31, 2024 and 2023, there were no transfers between Level 1, Level 2 and Level 3.

    The fair value of Level 2 instruments classified as marketable securities are typically determined through third-party pricing services. The pricing services use many observable market inputs to determine value, including reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, and current spot rates.

    The outstanding shares of Series 1 nonconvertible preferred stock as of December 31, 2024 and September 30, 2024 are measured at fair value. These outstanding shares are financial instruments that might require a transfer of assets because of the liquidation features in the contract and are therefore recorded as liabilities and measured at fair value. The fair value of the outstanding shares is based on significant inputs not observable in the market, which represent a Level 3 measurement within the fair value hierarchy. The Company utilizes a probability-weighted valuation model which takes into consideration various outcomes that may require the Company to transfer assets upon liquidation. Changes in the fair values of the Series 1 nonconvertible preferred stock are recognized in other income (expense) in the condensed consolidated statements of operations.

    The recurring Level 3 fair value measurements of the Company’s outstanding Series 1 nonconvertible preferred stock using probability-weighted discounted cash flow include the following significant unobservable inputs:

    There were no changes in the fair value of nonconvertible preferred stock during the three months ended December 31, 2024 and 2023.

    In April 2023, the Company entered into a royalty sale agreement with an affiliate of OMERS, pursuant to which the Company was paid a $200,000 cash purchase price in exchange for 54.5% of future quarterly royalty payments on net sales of

    10


    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 Company accounted for the upfront payment as a liability related to the sale of future royalties. The carrying value of the liability related to the sale of future royalties approximates fair value as of December 31, 2024 and is based on current estimates of future royalties expected to be paid to OMERS over the next 8 years, which are considered Level 3 inputs. See Note 8 for a rollforward of the liability.

    7. 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 $1,326,000 through December 31, 2024. Since the Company satisfied all of its performance obligations under the AbbVie Agreement by the end of fiscal 2011, all milestone payments received since then have been recognized as revenue when the milestones were achieved by AbbVie.

    The Company is receiving annually tiered royalties per Company protease product ranging from ten percent up to twenty percent, or on a blended basis from ten percent up to the high teens, on the portion of AbbVie’s calendar year net sales of each HCV regimen that is allocated to the protease inhibitor in the regimen. Beginning with each January 1, the cumulative net sales of a given royalty-bearing protease inhibitor product start at zero for purposes of calculating the tiered royalties on a product-by-product basis.

    8. 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 $200,000 cash purchase price in exchange for 54.5% of 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.

    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 the condensed consolidated statements of operations.

    The Company’s liability related to the sale of future royalties is estimated based on forecasted worldwide MAVYRET/MAVYRET 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 December 31, 2024, the estimated future cash flows resulted in an effective annual imputed interest rate of approximately 5.8%.

    The following table summarizes the activity of the liability related to the sale of future royalties:

    9. Series 1 Nonconvertible Preferred Stock

    As of December 31, 2024, 1,930 shares of Series 1 nonconvertible preferred stock were issued and outstanding. The outstanding shares are financial instruments that might require a transfer of assets because of the liquidation features in the contract and are carried at fair value as a liability on the Company’s condensed consolidated balance sheets.

    As of December 31, 2024, the Company had an aggregate of $31,787 of unrecognized stock-based compensation cost, which is expected to be recognized over a weighted average period of 2.3 years.

    11. Income Taxes

    For the three months ended December 31, 2024 and 2023, the Company recorded an income tax benefit of $416 and $622 respectively, due to interest recorded on a pending federal income tax refund.

    12. Commitments and Contingencies

    Litigation and Contingencies Related to Use of Intellectual Property

    From time to time, the Company may become subject to legal proceedings, claims and litigation arising in the ordinary course of business. Except as described below, the Company currently is not a party to any material threatened or pending litigation. However, third parties might allege that the Company or its collaborators are infringing their patent rights or that the Company is otherwise violating their intellectual property rights. Such third parties may resort to litigation against the Company or its collaborators, which the Company has agreed to indemnify. 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.

    14


    In June 2022, the Company announced that it filed suit in the United States District Court for the District of Massachusetts on June 21, 2022, 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. The Company is seeking fair compensation for Pfizer’s use of a coronavirus protease inhibitor claimed in the ‘953 patent. In May 2024, the Company and Pfizer each filed motions for summary judgment and a hearing on the motions was held on July 31, 2024. On December 23, 2024, the District Court issued a summary judgment decision ruling that the asserted claims of the ’953 Patent were invalid. In its decision, the District Court also denied the Company’s partial motion for summary judgment of infringement as moot in light of its allowance of summary judgment on invalidity. On February 3, 2025, the Company filed a notice of appeal with the United States Court of Appeals for the Federal Circuit. The timing for a decision on the appeal is currently uncertain. The Company records all legal expenses associated with the patent infringement suit 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 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 December 31, 2024.

    Leases

    The Company has two real estate leases for properties located in Watertown, Massachusetts. The first lease is for office space located at 400 Talcott Avenue and the second lease is for office and laboratory space located at 4 Kingsbury Avenue.

    Future annual minimum facility and equipment lease payments, net of the tenant improvement allowance under the Company’s 4 Kingsbury Avenue lease, as of December 31, 2024, are as follows:

    Overview

    We are a biotechnology company that uses our robust, chemistry-driven approach and drug discovery capabilities to discover and develop small molecule drugs with an emphasis on virology and immunology.

    Virology:

    We discovered glecaprevir, the second of two antiviral protease inhibitors discovered and developed through our collaboration with AbbVie for the treatment of chronic infection with hepatitis C virus, or HCV. Glecaprevir is co-formulated as part of AbbVie’s leading brand of direct-acting antiviral, or DAA, combination treatment for HCV, which has been marketed under the tradenames MAVYRET® (U.S.) and MAVIRET® (ex-U.S.) (glecaprevir/pibrentasvir) since 2017.

    Our active development programs in virology are focused on respiratory syncytial virus, or RSV, the most common cause of bronchiolitis and pneumonia and leading cause of U.S. hospitalization in young children and a significant cause of respiratory illness in older adults, with estimates suggesting that on average each year RSV leads to three million hospitalizations globally in children under 5 years old and 177,000 hospitalizations in the U.S. in adults over the age of 65.

    We also have development programs in virology for the following disease targets:

    •
    SARS-CoV-2, the virus that causes COVID-19, with estimates suggesting that COVID-19 continues to have a disease burden greater than influenza, including persistent cases of infection often referred to as long COVID and hospitalization and death among the elderly and those with comorbidities, while new variants continue to emerge on a regular basis; and
    •
    Hepatitis B virus, or HBV, the most prevalent chronic hepatitis, which is estimated by the World Health Organization to affect close to 300 million individuals worldwide.

    Immunology:

    In immunology, we are designing and developing highly potent and selective, oral small molecule inhibitors for the treatment of inflammatory disease by targeting key mechanisms of immune response. Our initial focus has been on mechanisms involved in an overactive type 2 immune response, which is the reaction of the body's immune system when the body detects infections or allergens and sends out immune cells to fight them. An overactive response is a primary driver of a number of inflammatory diseases.

    Our initial immunology targets involve the following mechanisms of immune response:

    •
    The receptor tyrosine kinase, known as KIT, which is critical for regulating mast cell activity; and
    •
    STAT6, a transcription factor uniquely responsible for interleukin-4 (IL-4)/interleukin-13 (IL-13) cell signaling, the factors that play important roles in regulating the responses of lymphocytes, myeloid cells, and non-hematopoietic cells within the immune system.

    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. We currently plan to focus our immunology drug development efforts on the following disease indications:

    •
    Chronic spontaneous urticaria, or CSU, a severely debilitating, chronic inflammatory skin disease manifested by hives, angioedema, which is swelling of soft tissues, or both, but with no identified triggers, which has an estimated global prevalence of between 0.5% – 1% of the population, resulting in approximately 1.75-3.5 million people with this condition at any given time in the U.S. alone; and
    •
    Atopic dermatitis, or AD, a chronic dermatological disease characterized by dry, red, inflamed, irritated and itchy skin with significant quality of life impacts such as leading a limited lifestyle, avoidance of social interactions and a reduced

    16


    range of activities, with AD affecting 7.3% of the US adult population, of whom approximately 40% have moderate to severe disease.

    As of December 31, 2024, we had $216.7 million in cash, cash equivalents and short-term marketable securities. We expect that our existing cash, cash equivalents, short-term marketable securities, as well as the cash flows from our retained portion of future HCV royalties and our forthcoming federal tax refund, will enable us to fund our operating expenses and capital expenditure requirements into fiscal 2028.

    Our Wholly-Owned Programs

    Our primary wholly-owned research and development programs are in virology and immunology.

    RSV. In virology, we have two clinical stage product candidates for RSV – zelicapavir (formerly EDP-938) and EDP-323. Both of these compounds are replication inhibitors that work by shutting down replication and the production of new virions, as opposed to the other mechanism in development of fusion inhibition that only blocks viral entry. Zelicapavir, which has Fast Track designation from the U.S. Food and Drug Administration, or FDA, is a potent inhibitor of the RSV N-protein for both major subgroups of RSV, referred to as RSV-A and RSV-B. Zelicapavir is being studied in two Phase 2 studies, each in a different high risk patient population. EDP-323, which also has a Fast Track designation from the FDA, is an inhibitor of the RSV L-protein for both major subgroups of RSV that has recently completed a Phase 2 challenge study.

    •
    Zelicapavir - N-protein Inhibitor Candidate: We have studied zelicapavir in two Phase 2 studies that were designed to be proof-of-concept and exploratory studies in otherwise healthy young adults (not at high-risk for serious outcomes with RSV) to understand the viral response in the context of RSV infection. With these studies, zelicapavir has demonstrated a favorable safety profile, consistent with that observed in over 500 subjects exposed to zelicapavir to date. We believe that zelicapavir has the greatest potential to show optimal efficacy in high-risk populations since these patients have reduced RSV immunity, which manifests in a higher and longer duration of viral load and greater disease severity, allowing a bigger window to realize the full potential of zelicapavir. Based on its growing safety profile, we are continuing to evaluate zelicapavir in high-risk populations, including pediatric patients and high-risk adults, all of which have significant unmet need:
    o
    Pediatric Study of Zelicapavir: On December 9, 2024, we announced positive topline results from the first-in-pediatrics Phase 2 study evaluating zelicapavir in hospitalized and non-hospitalized children aged 28 days to 36 months with RSV. This Phase 2 study was a randomized, double-blind, dose ranging, placebo-controlled study in hospitalized and non- hospitalized pediatric patients with RSV aged 28 days to 36 months.
    ▪
    Zelicapavir demonstrated a favorable safety profile over the initial 5-day dosing period and through 23 days of follow-up. There were no adverse effects leading to treatment discontinuation or study withdrawal.
    ▪
    Zelicapavir achieved target drug exposure levels across all age groups and dosing cohorts. Exposure was similar across cohorts and doses, and all patients received a therapeutic dose. A dose of 5 mg/kg was selected for patients aged ≥ 28 days to <12 months, and a dose of 7.5 mg/kg was selected for patients aged ≥12 months to ≤ 36 months.
    ▪
    An antiviral effect was observed for the primary and secondary virology endpoints in the overall pooled efficacy population, with the viral load decline peaking at 0.7 log on Day 9 compared to placebo. The primary endpoint for Part 2 of the study showed a more pronounced effect, with a viral load decline of 1.0 log at Day 3 and 1.4 log at Day 5 compared to placebo. Additionally, a rapid and robust antiviral effect was observed in the prespecified subset of patients who were randomized within 3 days of symptom onset, which represents about 40% of patients in the study (n=38/96). In these patients, a viral load decline of 0.9 log at Day 3 and 1.2 log at Day 5 was observed compared to placebo. Furthermore, zelicapavir treatment resulted in a greater proportion of patients having undetectable viral load at Days 5 and 9 compared to placebo and improvements in area under the curve (AUC) of change from baseline for viral load at all timepoints. Qualitative improvement in time to undetectable viral load was observed at early timepoints, although median time to undetectable viral load was similar between groups. Overall, virology results were similar regardless of age or whether patients were enrolled from a hospitalized or outpatient setting.
    o
    High-Risk Adults Study of Zelicapavir: We also have an ongoing Phase 2b study in high-risk adults, including those who are older than 65 years of age and those who have asthma, chronic obstructive pulmonary disease, or COPD, or congestive heart failure. Approximately 180 patients will be treated with zelicapavir or placebo for five days with a primary endpoint of time to resolution of RSV lower respiratory tract disease symptoms. Enrollment is progressing and we are targeting enrollment completion in the current Northern Hemisphere RSV season with topline data expected in the third quarter of 2025.

    17


    •
    EDP-323 - L-protein Inhibitor Candidate: Our second clinical RSV candidate, EDP-323, is a novel oral, direct-acting antiviral selectively targeting the RSV L-protein, a viral RNA-dependent RNA polymerase enzyme that contains multiple enzymatic activities required for RSV replication. EDP-323 has sub-nanomolar potency against RSV-A and RSV-B in vitro and protected mice in a dose-dependent manner from RSV infection as demonstrated by both virological and pathological endpoints. EDP-323 is not expected to have cross-resistance to other classes of inhibitors and has the potential to be used alone, or in combination with other RSV mechanisms, to broaden the treatment window or addressable patient populations.
    o
    Phase 2a Study of EDP-323: In September 2024, we announced positive topline results for EDP-323 in a Phase 2a challenge study of healthy adults infected with RSV. Treatment with EDP-323 achieved highly statistically significant (p=<0.0001) reductions in both viral load and clinical symptoms compared to placebo. Overall, EDP-323 was generally well tolerated and demonstrated a favorable safety profile that was comparable to placebo over 5 days of dosing through Day 28 of follow-up. There were no serious adverse events and no discontinuations of EDP-323.

    COVID-19. We leveraged our expertise in developing protease inhibitors to discover compounds specifically designed to target the SARS-CoV-2 virus and potentially other coronaviruses. We selected EDP-235, an oral inhibitor of the coronavirus 3CL protease, also referred to as 3CLpro or the main coronavirus protease, or Mpro, for clinical development. In addition to nanomolar activity against all SARS-CoV-2 variants tested to date, EDP-235 has potent antiviral activity against other human coronaviruses, enabling the potential for a pan-coronavirus treatment, including possibly coronaviruses that may infect human populations in the future. Furthermore, EDP-235 has good tissue distribution, and is projected to have four times higher drug levels in lung tissue compared to plasma.

    •
    SPRINT Study of EDP-235: In May 2023, we reported topline results from a Phase 2 clinical trial of EDP-235 in non-hospitalized, symptomatic patients with mild to moderate COVID-19 who were not at increased risk for developing severe disease, which was the only study population permitted by the FDA. EDP-235 met the primary endpoint of the trial and was generally safe and well-tolerated.
    o
    A dose-dependent improvement in total symptom score was observed with EDP-235 treatment compared to placebo, which achieved statistical significance (p<0.05) in the 400 mg treatment group at multiple time points, starting as early as one day after the first dose.
    o
    An analysis of a subset of six symptoms showed a two-day shorter time (5 days to 3 days) to improvement in patients receiving EDP-235 400 mg who were enrolled within three days of symptom onset (p<0.01).
    o
    No effect on virologic endpoints as measured in the nose was detected due to the rapid viral decline in the placebo arm of this highly immunologically-experienced, standard risk population.
    o
    In the subset of patients who were nucleocapsid seronegative (indicating no recent natural infection with SARS-CoV-2), a viral load decline was observed at day five in the 400 mg group of 0.8 log overall and 1 log in the patients with symptom onset within three days before treatment with EDP-235.

    We will continue to focus on potential collaborations to progress EDP-235, as we will not advance this candidate into Phase 3 studies on our own.

    Immunology. We are designing and developing highly potent and selective, oral, small molecule inhibitors targeting the following mechanisms of immune response:

    •
    KIT Inhibitors. We have a preclinical stage program to develop oral KIT inhibitors to treat CSU and potentially other indications by depleting mast cells, thereby addressing a primary driver of these diseases. We have discovered novel, potent and selective oral KIT inhibitors, which are in preclinical development. In the fourth quarter of 2024, we selected our lead development candidate, EPS-1421. This candidate demonstrates potent nanomolar activity in both binding and cellular function assays, with sub-nanomolar activity in vivo, and is highly selective for KIT versus other kinases. This inhibitor also demonstrates strong in vitro and in vivo absorption, distribution, metabolism and excretion (ADME) properties. We expect to conduct scale-up activities and IND-enabling studies for this program in 2025.
    •
    STAT6 Inhibitors. We have a discovery stage program to develop oral STAT6 inhibitors for the treatment of type 2 immune driven diseases, initially focusing on AD and potentially other indications by blocking the IL-4/IL-13 signaling pathway, thereby addressing a primary driver of these diseases. We have discovered novel, potent and selective oral STAT6 inhibitors, which are being optimized in the discovery stage. Our prototype inhibitors demonstrate potent activity and high selectivity for STAT6 over other STATs in both biochemical and cellular assays, including SH2 domain selectivity against non-STAT proteins, and also demonstrate systemic in vivo target engagement after ex vivo IL-4 stimulation. We are continuing to evaluate multiple compounds in preclinical studies, including toxicology studies, and conducting lead optimization activities. Our goal is to select a lead development candidate in the second half of 2025.

    18


    •
    We plan to expand our presence in immunology with the introduction of a third program in 2025.

    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:

    **Continued development dependent on a future collaboration

    ***Initial indications. Potential future indications include asthma, chronic inducible urticaria (CIndU), eosinophilic esophagitis (EoE), prurigo nodularis (PN) and others.

    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 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 2-DAA 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 condensed 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. As of the date of this report, we are conducting a Phase 2b study of zelicapavir in high risk adults and have recently completed a Phase 2b study of zelicapavir in pediatric patients and a Phase 2a human challenge study of EDP-323. We are also conducting preclinical research and discovery efforts in the field of immunology.

    19


    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. However, in the next 12 months, we anticipate a reduction in our external research and development expenses, primarily driven by the completion of the Phase 2a human challenge study of EDP-323 and the Phase 2b study of zelicapavir in pediatric patients. These milestones, along with strategic adjustments, have positioned us to reduce spending in 2025 while maintaining our commitment to advancing key 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 marketable securities. We believe that our existing cash, cash equivalents and short-term marketable securities, as well as the cash flows from our retained portion of future HCV royalties and our forthcoming federal tax refund, will enable us to fund our operating expenses and capital expenditure requirements into fiscal 2028.

    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 chronic HCV.

    The following table is a summary of revenue recognized for the three months ended December 31, 2024 and 2023:

    AbbVie Agreement

    To date, we have received annually tiered, double-digit royalties on our protease inhibitor product glecaprevir included in AbbVie’s net sales of MAVYRET/MAVIRET. Under the terms of our AbbVie Agreement, 50% of AbbVie’s net sales of MAVYRET/MAVIRET are allocated to glecaprevir. Beginning with each January 1, the cumulative net sales of MAVYRET/MAVIRET start at zero for purposes of calculating the tiered royalties. As disclosed above regarding the 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 Phase 1 or Phase 2 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:

    •
    third-party contract costs relating to research, formulation, manufacturing, preclinical study, and clinical trial activities;
    •
    personnel costs, including salaries, related benefits, and stock-based compensation for employees engaged in scientific research and development functions;
    •
    allocated facility-related costs;
    •
    laboratory consumables; and
    •
    third-party license fees.

    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

    20


    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 anticipate a reduction in our external research and development expenses, primarily driven by the completion of the Phase 2a human challenge study of EDP-323 and the Phase 2b study of zelicapavir in pediatric patients. These milestones, along with strategic adjustments, have positioned us to reduce spending in 2025 while maintaining our commitment to advancing key 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.

    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 travel expenses, 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 suit.

    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, but we anticipate inflation may impact future periods.

    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 Benefit (Expense)

    Income tax benefit (expense) 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 $17.0 million during the three months ended December 31, 2024 as compared to $18.0 million during the three months ended December 31, 2023. The $1.0 million decrease in revenue was primarily due to AbbVie’s lower reported HCV sales as compared to the comparable period in 2023.

    21


    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 and the number of patients treated. 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 quarter 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 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 December 31, 2024 decreased by $8.7 million compared to the same period in 2023.

    Virology

    The costs in our virology program decreased $9.0 million primarily due to timing of our clinical trials in our RSV program and to a lesser extent, a decrease in costs associated with our COVID-19 program as we stopped further internal development and will only progress the program in the context of one or more collaborations.

    Immunology

    The costs in our immunology programs increased by $2.5 million primarily due to the scale-up and IND-enabling activities related to our KIT program and the initiation of preclinical studies for our STAT6 program.

    Other Programs

    Other program costs decreased by $2.2 million primarily due to the completion of the discovery and optimization activities related to our STAT6 program.

    General and administrative expenses

    General and administrative expenses decreased by $3.7 million for the three months ended December 31, 2024 compared to the same period in 2023. The change was primarily due to a decrease in legal expenses related to our patent infringement suit against Pfizer.

    22


    Other income (expense)

    Changes in components of other income (expense) were as follows:

    Interest expense

    Interest expense decreased $1.5 million for the three months ended December 31, 2024, as compared to the same period in 2023 due to the paydown of our obligation associated with our royalty sale agreement entered into during April 2023 with an affiliate of OMERS.

    Interest and investment income, net

    Interest and investment income, net, decreased $1.5 million for the three months ended December 31, 2024, as compared to the same period in 2023. The decrease was due to lower cash and investment balances year over year.

    Income tax benefit

    During the three months ended December 31, 2024 and 2023, we recorded an income tax benefit of $0.4 million and $0.6 million, respectively, primarily related to interest recorded on a pending federal tax refund.

    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 December 31, 2024, our principal sources of liquidity were cash and cash equivalents and short-term marketable securities of $216.7 million.

Our cash used in operating activities decreased $8.2 million primarily due to lower research and development payments, offset by lower cash receipts associated with our AbbVie agreement.

    23


    Net cash provided by (used in) investing activities

    Cash provided by investing activities was $68.9 million for the three months ended December 31, 2024 as compared to cash used in investing activities of $13.1 million for the same period in 2023. Our cash provided by investing activities increased $82.0 million, driven by the timing of maturities of marketable securities in 2024 compared to 2023.

    Net cash used in financing activities

    Cash used in financing activities was $5.0 million for the three months ended December 31, 2024 as compared to cash used in financing activities of $7.4 million for the same period in 2023. Our cash used in financing activities decreased $2.4 million, driven primarily by lower payments on our royalty sale agreement with OMERS.

    Funding Requirements

    As of December 31, 2024, we had $216.7 million in cash, cash equivalents and short-term marketable securities. We believe that our existing cash, cash equivalents and short-term marketable securities as of December 31, 2024, as well as the cash flows from our retained portion of future HCV royalties and our forthcoming federal tax refund, will enable us to fund our operating expenses and capital expenditure requirements into fiscal 2028. 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:

    •
    the number and characteristics of our research and development programs;
    •
    the scope, progress, results and costs of researching and developing our product candidates on our own, including conducting advanced clinical trials;
    •
    our ability to establish new collaborations, licensing or other arrangements, if any, and the financial terms of such arrangements;
    •
    the amount of our retained portion of royalties generated from MAVYRET/MAVIRET sales under our existing collaboration with AbbVie;
    •
    delays and additional expenses in our clinical trials;
    •
    the cost of manufacturing our product candidates for clinical development and any products we successfully commercialize independently;
    •
    opportunities to in-license or otherwise acquire new technologies and therapeutic candidates;
    •
    costs associated with prosecuting our patent infringement suit regarding use of a coronavirus 3CL protease inhibitor in Paxlovid, Pfizer's antiviral treatment for COVID-19;
    •
    the timing of, and the costs involved in, obtaining regulatory approvals for any product candidates we develop independently;
    •
    the cost of commercialization activities, if any, of any product candidates we develop independently that are approved for sale, including marketing, sales and distribution costs;
    •
    the timing and amount of any sales of our product candidates, if any, or royalties thereon;
    •
    the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patents, including any litigation costs and the outcomes of any such litigation; and
    •
    potential fluctuations in foreign currency exchange rates.

    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.

    24


    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 $6.7 million for the remainder of 2025, $8.5 million in 2026, $8.7 million in 2027, $9.0 million in 2028, $9.3 million in 2029, and $50.6 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.
