    NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

    (UNAUDITED)

     

     

    1. Condensed Consolidated Financial Statements

     

    The financial statements of SIGA Technologies, Inc. (“we,” “our,” “us,” “SIGA” or the “Company”) are presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission for quarterly reports on Form 10-Q and should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended December 31, 2025, included in the Company's 2025 Annual Report on Form 10-K filed on March 10, 2026 (the "2025 Form 10-K"). All terms used but not defined elsewhere herein have the meaning ascribed to them in the 2025 Form 10-K. In the opinion of management, all adjustments (consisting of normal and recurring adjustments) considered necessary for a fair statement of the results of the interim periods have been included. The 2025 year-end condensed consolidated balance sheet data were derived from the audited financial statements but do not include all disclosures required by U.S. GAAP. The results of operations for the three months ended March 31, 2026, are not necessarily indicative of the results expected for the full year.

     

     

    2. Summary of Significant Accounting Policies

     

    Revenue Recognition

    The Company accounts for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). In all transactions, the Company is the principal as it controls the specified good or service before it is transferred to the customer and therefore recognizes revenue on a gross basis. A contract’s transaction price is allocated to distinct performance obligations and recognized as revenue when, or as, a performance obligation is satisfied. As of March 31, 2026, the Company's active contractual performance obligations consist of the following: three performance obligations relate to research and development services; and two relate to manufacture and delivery of product. The material performance obligations are referenced in Note 3. The aggregate amount of the transaction price allocated to current performance obligations as of  March 31, 2026 was $65.6 million. Current performance obligations represent the transaction price for which work has not been performed and excludes unexercised contract options. With respect to current obligations related to the manufacture and delivery of product, the Company expects such obligations to be recognized as revenues within the next 12 months. With respect to the performance obligations related to research and development services, the Company expects such obligations to be recognized as revenue within the next three years as the specific timing for satisfying performance obligations is subjective and at times outside the Company's control.

     

    Performance Obligations

    A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. 

     

    Contract modifications may occur during the course of performance of our contracts. Contracts are often modified to account for changes in contract specifications or requirements. In most instances, contract modifications are for services that are not distinct, and, therefore, are accounted for as part of the existing contract.

     

    The Company’s performance obligations are satisfied over time as work progresses or at a point in time. A portion of the Company's revenue is derived from long-term contracts that span multiple years. All of the Company’s revenue related to current research and development performance obligations as well as certain product supportive services are recognized over time, because the customer simultaneously receives and consumes the benefits provided by the services as the Company performs these services. The Company recognizes revenue related to these services based on the progress toward complete satisfaction of the performance obligation and measures this progress under an input method, which is based on the Company’s cost incurred relative to total estimated costs.  Under this method, progress is measured based on the cost of resources consumed (i.e., cost of third-party services performed, cost of direct labor hours incurred, and cost of materials consumed) compared to the total estimated costs to completely satisfy the performance obligation. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. The incurred and estimated costs used in the measure of progress include third-party services performed, direct labor hours, and material consumed. The Company accounts for shipping and handling activities as fulfillment costs rather than as an additional promised service.  

     

    Contract Balances

    The timing of revenue recognition, billings and cash collections may result in billed accounts receivable, unbilled receivables (contract assets) and customer advances and deposits (contract liabilities) in the condensed consolidated balance sheets. Generally, amounts are billed as work progresses in accordance with agreed-upon contractual terms either at periodic intervals (monthly) or upon achievement of contractual milestones. Under typical payment terms of fixed price arrangements, the customer pays the Company either performance-based payments or progress payments. For the Company’s cost-type arrangements, the customer generally pays the Company for its actual costs incurred, as well as its allocated overhead and G&A costs. Such payments occur within a short period of time from billing. When the Company receives consideration, or such consideration is unconditionally due, prior to transferring goods or services to the customer under the terms of a sales contract, the Company records deferred revenue, which represents a contract liability. Revenue recognized during the three months ended March 31, 2026 that was included in the contract liability balance at the beginning of the period was $0.8 million.

    Recent Accounting Pronouncements

    In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the consolidated financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.

     

     

    3. Procurement Contracts and Research Agreements

     

    19C BARDA Contract 

    On September 10, 2018, the Company entered into a contract with the U.S. Biomedical Advanced Research and Development Authority ("BARDA") pursuant to which SIGA agreed to deliver up to 1,488,000 courses of oral TPOXX® to the U.S. Strategic National Stockpile ("Strategic Stockpile"), and to manufacture and deliver to the Strategic Stockpile, or store as vendor-managed inventory, up to 212,000 courses of IV TPOXX®. In October 2023, the contract was modified so that a course of IV TPOXX® was redefined within the contract from being 14 vials to being 28 vials; as such, the 19C BARDA Contract currently specifies 106,000 courses of IV TPOXX® (for the same payment amount as originally specified). In addition to the delivery of TPOXX® courses, the contract includes funding from BARDA for a range of activities, including: advanced development of IV TPOXX®, post-marketing activities for oral and IV TPOXX®, development of a pediatric formulation, support for manufacturing activities, and procurement activities. On April 8, 2025, total payments contemplated under the contract with BARDA were increased by $14.3 million to add funding for activities supporting manufacturing. On June 3, 2025, total payments contemplated under the contract with BARDA were increased by $13.2 million in connection with the development of the pediatric formulation of TPOXX®. As of March 31, 2026, the contract with BARDA (as amended, modified, or supplemented from time to time, the "19C BARDA Contract") contemplates up to approximately $630 million of payments, of which approximately $79.2 million of payments are included within the base period of performance, approximately $545.2 million of payments are related to exercised options, and up to approximately $5.6 million of payments are currently specified as unexercised options. BARDA may choose in its sole discretion when, or whether, to exercise any of the unexercised options. The period of performance for options is up to ten years from the date of entry into the 19C BARDA Contract and such options could be exercised at any time during the contract term.  

     

    The base period of performance specifies potential payments of approximately $79.2 million for the following activities: payments of approximately $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile; payments of $8.0 million for the manufacture of 10,000 courses (as currently defined within the contract as being 28 vials) of final drug product of IV TPOXX® ("IV FDP"), of which $3.2 million of payments are related to the manufacture of bulk drug substance ("IV BDS") to be used in the manufacture of IV FDP; payments of approximately $59.5 million to fund reimbursed activities; and payments of approximately $0.6 million for supportive procurement activities. As of March 31, 2026, the Company had received $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile, $3.2 million for the manufacture of IV BDS, $4.8 million for the delivery of IV FDP to the Strategic Stockpile and $34.0 million for other base period activities. IV BDS has been used for the manufacture of courses of IV FDP. The $3.2 million received for the completed manufacture of IV BDS had been recorded as deferred revenue as of December 31, 2021, but with the delivery of IV FDP to the Strategic Stockpile during 2022, $2.9 million was recognized as revenue. The remaining $0.3 million of deferred revenue was recognized in the second quarter of 2024 as the IV FDP containing such IV BDS was delivered to and accepted by the Strategic Stockpile.

     

    The options that have been exercised as of  March 31, 2026, provide for payments up to approximately $545.2 million. As of  March 31, 2026, there are exercised options for the following activities: payments up to $450.2 million for the manufacture and delivery of up to 1.5 million courses of oral TPOXX®; payments up to $76.8 million for the manufacture of courses of IV FDP; payments of up to approximately $3.6 million to fund post-marketing activities for IV TPOXX®; and payments of up to $14.6 million for funding of post-marketing activities for oral TPOXX®. As of March 31, 2026, a cumulative total of $450.2 million of oral TPOXX® has been delivered to the Strategic Stockpile and accepted; a cumulative total of $61.4 million of IV BDS or IV FDP has been either set aside in inventory or delivered to the Strategic Stockpile and accepted (IV BDS that has been set aside has been recorded as deferred revenue and will be recognized as revenue when the IV BDS is manufactured as IV FDP and delivered); and the Company has been cumulatively reimbursed $11.9 million in connection with post-marketing activities for oral and IV TPOXX®.  

     

    Unexercised options specify potential payments up to approximately $5.6 million in total (if all such options are exercised), all of which relates to supportive activities that we currently do not expect to be required.

    Table of Contents
     

    The options related to IV TPOXX® were divided into two primary manufacturing steps. There were options related to the manufacture of bulk drug substance (“IV BDS Options”), and there were corresponding options (for the same number of IV courses) for the manufacture of final drug product (“IV FDP Options”). BARDA had the sole discretion to choose to exercise any, all, or none of these options. The 19C BARDA Contract included: three separate IV BDS Options, each providing for the bulk drug substance equivalent of 32,000 courses (as currently defined within the contract) of IV TPOXX®; and three separate IV FDP Options, each providing for 32,000 courses of final drug product of IV TPOXX®. BARDA had the sole discretion as to whether to simultaneously exercise IV BDS Options and IV FDP Options, or whether to exercise options at different points in time (or alternatively, to only exercise the IV BDS Option but not the IV FDP Option). To date, BARDA has exercised all three IV BDS options and all three IV FDP options. 

     

    Revenues in connection with the 19C BARDA Contract are recognized either over time or at a point in time. Performance obligations related to product delivery generate revenue at a point in time. Revenue from other performance obligations under the 19C BARDA Contract are recognized over time using an input method using costs incurred to date relative to total estimated costs at completion. For the three months ended March 31, 2026 and 2025, the Company recognized revenues of $5.1 million and $1.2 million, respectively, on an over time basis. In contrast, revenue recognized for product delivery, and therefore at a point in time, for the three months ended March 31, 2026 was $1.2 million. No revenue was recognized for product delivery, and therefore no revenue was recognized at a point in time, for the three months ended March 31, 2025. 

     

    International Sales Activity

    Revenue in connection with international procurement contracts for the delivery of product are recognized at a point in time on a gross basis, as the Company acts as the principal in the transaction. During the three months ended March 31, 2026, the Company did not recognize any international sales. During the three months ended March 31, 2025, the Company recognized $5.8 million of international sales consisting of a delivery of oral TPOXX® to one country.

    International Commercial Agreements

     

    MENA License Agreement

     

    In March 2026, the Company entered into an exclusive license and distribution agreement with Hikma MENA FZE (“Hikma”) that gives Hikma the right to register and commercialize oral TPOXX® in the Middle East and North Africa (MENA) region. Under the terms of the agreement, the Company will be the sole manufacturer of tecovirimat and will supply finished product to Hikma.

     

    Meridian Agreement 

     

    Under the terms of the current International Promotion Agreement, which was amended on March 27, 2024, and effective June 1, 2024, and further amended on August 30, 2024, the Company has primary responsibility for the advertising, promotion and sale of oral TPOXX® in all geographic regions. Meridian has limited, non-exclusive rights to advertise, promote, offer for sale and sell oral TPOXX® in the European Economic Area, Australia, Japan, Switzerland, the United Kingdom and the Association of Southeast Asian Nations and its member states (collectively, the “Current Territory”). Meridian also performs non-promotional activities under specified contracts with third parties entered into prior to June 1, 2024, that provide for the sale of oral TPOXX® in the Current Territory. The International Promotion Agreement entitles Meridian to receive a fee equal to a high single digit percentage of collected proceeds (whether collected by Meridian or the Company), net of certain expenses, of sales of oral TPOXX® in the Current Territory in the field of use specified in the International Promotion Agreement. The International Promotion Agreement has a fixed term that expires on May 31, 2026, with no automatic renewal.

     

    Under the terms of the original International Promotion Agreement (“Pre-amendment International Promotion Agreement”), which had an initial term that expired on May 31, 2024, Meridian had been granted exclusive rights to market, advertise, promote, offer for sale, or sell oral TPOXX® in a field of use specified in the International Promotion Agreement in all geographic regions except for the United States (the “Territory”), and Meridian agreed not to commercialize any competing product, as defined in the Pre-amendment International Promotion Agreement, in the specified field of use in the Territory. Under the Pre-amendment International Promotion Agreement, as well as the current International Promotion Agreement, SIGA has always retained ownership, intellectual property, distribution and supply rights and regulatory responsibilities in connection with TPOXX®, and, in the United States market, also retained sales and marketing rights with respect to oral TPOXX®. SIGA’s consent is required prior to the entry by Meridian into any sales arrangement pursuant to the International Promotion Agreement.

     

    Sales to international customers pursuant to the Pre-amendment International Promotion Agreement were invoiced and collected by Meridian, and such collections were remitted, less Meridian’s fees, to the Company under a quarterly process specified in the Pre-amendment International Promotion Agreement; and Meridian was entitled to a specified percentage of the collected proceeds of sales of oral TPOXX®, net of certain expenses, for calendar years in which customer collected amounts net of such expenses were less than or equal to a specified threshold, and to a higher specified percentage of such collected net proceeds for calendar years in which such net collected amounts exceeded the specified threshold. Subsequent to June 1, 2024, only specified procurement contracts for the Current Territory entered into prior to June 1, 2024, continue to involve Meridian invoicing and collecting proceeds, and retaining a fee pursuant to the International Promotion Agreement.

    7. Fair Value of Financial Instruments

     

    The carrying value of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other current liabilities, and income tax payable approximates fair value due to the relatively short maturity of these instruments. 

     

    The measurement of fair value requires the use of techniques based on observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. The inputs create the following fair value hierarchy:

     

     

    •

    Level 1 – Quoted prices for identical instruments in active markets.

     

     

    •

    Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations where inputs are observable or where significant value drivers are observable.

     

     

    •

    Level 3 – Instruments where significant value drivers are unobservable to third parties.

     

    There were no transfers between levels of the fair value hierarchy for the three months ended March 31, 2026. As of  March 31, 2026 and December 31, 2025, the Company had $56.3 million and $55.8 million, respectively, of cash equivalents classified as Level 1 financial instruments. There were no Level 2 or Level 3 financial instruments as of  March 31, 2026 or December 31, 2025.

     

     

    8. Per Share Data

     

    The Company computes, presents and discloses earnings per share in accordance with the authoritative guidance, which specifies the computation, presentation and disclosure requirements for earnings per share of entities with publicly held common stock or potential common stock. The objective of basic EPS is to measure the performance of an entity over the reporting period by dividing income by the weighted average shares outstanding. The objective of diluted EPS is consistent with that of basic EPS, except that it also gives effect to all potentially dilutive common shares outstanding during the period.

     

    The following is a reconciliation of the basic and diluted earnings per share computation: 

     

      

    Three Months Ended March 31,

     
      

    2026

      

    2025

     

    Net loss for basic earnings per share

     $(3,454,252) $(408,223)

    Effect of potential common shares

    Loss per share: basic

     $(0.05) $(0.01)

    Loss per share: diluted

     $(0.05) $(0.01)

     

    For the three months ended March 31, 2026 and 2025, the Company incurred a loss and as a result, the equity instruments listed below were excluded from the calculation of diluted loss per share as the effect of the exercise, conversion or vesting of such instruments would have been anti-dilutive. The weighted average number of equity instruments excluded consists of:

    9. Commitments and Contingencies

     

    From time to time, we may be involved in a variety of claims, suits, investigations and proceedings arising from the ordinary course of our business, collections claims, breach of contract claims, labor and employment claims, tax and other matters. Although such claims, suits, investigations and proceedings are inherently uncertain and their results cannot be predicted with certainty, we believe that the resolution of such current pending matters, if any, will not have a material adverse effect on our business, consolidated financial position, results of operations or cash flow. Regardless of the outcome, litigation can have an adverse impact on us because of legal costs, diversion of management resources and other factors.

     

    Purchase Commitments

    In the course of our business, the Company regularly enters into agreements with third party organizations to provide contract manufacturing services and research and development services. Under these agreements, the Company issues purchase orders, which obligate the Company to pay a specified price when agreed-upon services are performed. In connection with many CMO purchase orders, reimbursement by CMOs for inventory losses is limited. Commitments under the purchase orders do not exceed our planned commercial and research and development needs. As of March 31, 2026, the Company had approximately $3.5 million of purchase commitments associated with manufacturing obligations.

    Real Estate Leases

    On May 26, 2017, the Company and MacAndrews & Forbes Incorporated ("M&F") entered into a ten-year Office Lease agreement (the "New HQ Lease"), pursuant to which the Company agreed to lease 3,200 square feet at 31 East 62nd Street, New York, New York. The Company is utilizing premises leased under the New HQ Lease as its corporate headquarters. The Company's rental obligations consisted of a fixed rent of $25,333 per month in the first sixty-three months of the term, subject to a rent abatement for the first six months of the term. From the first day of the sixty-fourth month of the term through the expiration or earlier termination of the lease, the Company's rental obligations consist of a fixed rent of $29,333 per month. In addition to the fixed rent, the Company will pay a facility fee in consideration of the landlord making available certain ancillary services, commencing on the first anniversary of entry into the lease. The facility fee was $3,333 per month for the second year of the term and increases by five percent each year thereafter, to $4,925 per month in the final year of the term. During the three months ended March 31, 2026, the Company paid $0.1 million for rent and ancillary services associated with this lease. The Company had no outstanding payables or accrued expenses related to this lease as of March 31, 2026.

    11. Segment and Geographic Information

     

    The Company operates in one single operating and reportable segment, which includes all activities related to the sale of the Company’s oral and IV TPOXX® as well as research and development services. The Company derives revenue primarily from sales to the U.S. Government as well as international governments (including government affiliated entities) and manages the business activities on a consolidated basis. The segment derives revenues from customers through the delivery of product and fulfillment of research and development services.

     

    The Chief Operating Decision Maker ("CODM") assesses performance for the segment and decides how to allocate resources based on net income that also is reported on the income statement as consolidated net income. Consolidated net income is also a measure that is considered in monitoring budget versus actual results.

     

    The CODM does not review assets in evaluating the results of the segment, and therefore, such information is not presented.

     

    The following table provides the operating result of the Company's segment:

    12. Income Taxes 

     

    The Company’s provision for income taxes consists of federal and state taxes, as applicable, in amounts necessary to align the Company’s year-to-date tax provision with the effective rate that it expects to achieve for the full year. Each quarter the Company updates its estimate of the annual effective tax rate and records cumulative adjustments as necessary.

     

    For the three months ended March 31, 2026 and 2025, we recorded pre-tax loss of ($4.0) million and ($0.6) million, respectively, and a corresponding income tax benefit of $0.6 million and $0.2 million, respectively. 

     

    The effective tax rate for the three months ended March 31, 2026 was 14.6% compared to 28.4% for the three months ended March 31, 2025. The effective tax rate for the three months ended March 31, 2026 and 2025 differed from the U.S. statutory rate of 21% primarily as a result of state taxes and various non-deductible expenses, including executive compensation under Internal Revenue Code Section 162(m).

    14. Leases

     

    The Company leases its Corvallis, Oregon, office space under an operating lease, which was signed on November 3, 2017 and commenced on January 1, 2018. The initial term of this lease was to expire on December 31, 2019 after which the Company had two successive renewal options; one for two years and the other for three years. In the second quarter of 2019, the Company exercised the first renewal option, which extended the lease expiration date to December 31, 2021. In the second quarter of 2021, the Company exercised the second renewal option, which extended the lease expiration date to December 31, 2024. In the second quarter of 2024, the Company entered into an additional addendum, which extended the lease expiration date to December 31, 2026. In connection with this additional addendum, the Company recorded an increase to operating lease right-of-use assets and operating lease liabilities of approximately $0.5 million in the second quarter of 2024.

     

    On May 26, 2017, the Company and M&F entered into the New HQ Lease, a ten-year office lease agreement, pursuant to which the Company agreed to lease 3,200 square feet in New York, New York. The Company is utilizing premises leased under the New HQ Lease as its corporate headquarters. The Company has no leases that qualify as finance leases.

     

    Operating lease costs totaled $0.2 million for each of the three months ended March 31, 2026 and 2025. Cash paid for amounts included in the measurement of lease liabilities from operating cash flows was $0.2 million for each of the three months ended March 31, 2026 and 2025. As of March 31, 2026, the weighted-average remaining lease term of the Company’s operating leases was 1.00 years while the weighted-average discount rate was 9.95%.

    Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

     

    The following discussion should be read in conjunction with our condensed consolidated financial statements and notes to those statements and other financial information appearing elsewhere in this Quarterly Report on Form 10-Q and in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the SEC on March 10, 2026 (the "2025 Form 10-K"). In addition to historical information, the following discussion and other parts of this Quarterly Report contain forward-looking information that involves risks and uncertainties. SIGA’s actual results could differ materially from those anticipated by such forward-looking statements due to a number of factors. See the factors set forth under the heading “Forward-Looking Statements” at the end of this Item 2, and in Item 1A. “Risk Factors” of the 2025 Form 10-K.

     

    Overview

     

    SIGA Technologies, Inc. (“SIGA” or the “Company”) is a commercial-stage pharmaceutical company. The Company sells its lead product, the oral formulation of TPOXX® (“oral TPOXX®,” also known as "tecovirimat," "Tecovirimat-SIGA," or "TEPOXX (tecovirimat)" in certain international markets), to the U.S. Government and international governments (including government affiliated entities). In certain international markets, the Company may sell TPOXX® through a distributor. Additionally, the Company sells the intravenous formulation of TPOXX® ("IV TPOXX®") to the U.S. Government.

     

    TPOXX® is an antiviral drug for the treatment of human smallpox disease caused by variola virus. On July 13, 2018, the United States Food & Drug Administration (“FDA”) approved oral TPOXX® for the treatment of smallpox. The Company has been delivering oral TPOXX® to the U.S. Strategic National Stockpile ("Strategic Stockpile") since 2013.

     

    On May 18, 2022, the FDA approved IV TPOXX® for the treatment of smallpox.

     

    In addition to being approved by the FDA, oral TPOXX® (tecovirimat) has received regulatory approval from the European Medicines Agency ("EMA"), Health Canada, the Medicines and Healthcare Products Regulatory Agency ("MHRA") of the United Kingdom, and the Japanese Pharmaceuticals and Medical Devices Agency ("PMDA"). The EMA, MHRA and PMDA approved oral TPOXX® for the treatment of smallpox, monkeypox ("mpox"), cowpox, and vaccinia complications following vaccination against smallpox. Health Canada approved TPOXX® for the treatment of smallpox.

     

    TPOXX® was authorized under “exceptional circumstances” by the EMA and the MHRA, under the brand name Tecovirimat-SIGA. These regulators granted marketing authorizations under “exceptional circumstances” because it was not possible to obtain complete efficacy and safety information about the product due to the rarity of smallpox and other orthopoxviruses and because ethical considerations prevented conducting the necessary clinical studies. The Tecovirimat-SIGA marketing authorizations under “exceptional circumstances” are subject to certain specific obligations to gather additional data post-approval to help confirm the product’s safety and efficacy. All “exceptional circumstances” marketing authorizations are subject to annual reassessments that consider whether data generated pursuant to the specific obligations continue to confirm its positive benefit-risk profile. These annual reassessments determine whether the product’s marketing authorization should be maintained, changed, suspended, or withdrawn based on its benefit-risk profile.

     

    On July 24, 2025, the EMA’s Committee for Medicinal Products for Human Use ("CHMP") closed its third annual reassessment for Tecovirimat-SIGA and initiated a referral procedure for the product following questions over its effectiveness in the treatment of mpox. These questions were raised following receipt of results from certain non-SIGA sponsored clinical trials evaluating tecovirimat as a potential mpox treatment including the PALM007 and STOMP clinical trials. In the referral procedure, CHMP reviewed all available data on the safety and efficacy of Tecovirimat-SIGA for all its authorized indications in order to make a recommendation to the European Commission whether the marketing authorization should be maintained, modified, suspended or withdrawn. On March 27, 2026, the CHMP issued its opinion following the conclusion of its review. CHMP confirmed the positive benefit-risk balance of Tecovirimat-SIGA as a treatment for smallpox, cowpox and vaccinia complications, and recommended, based on the results of the mpox clinical trials, that the product no longer be used for the treatment of mpox. In April 2026, the MHRA requested SIGA align the Tecovirimat-SIGA label in the U.K. with the outcome of the referral procedure.  

     

    With respect to the regulatory approvals by the EMA, PMDA, MHRA and Health Canada, oral tecovirimat represents the same formulation approved by the FDA in July 2018 under the brand name TPOXX®.

     

    In connection with a potential FDA label expansion of oral TPOXX® for an indication covering smallpox post-exposure prophylaxis (“PEP”), the Company has completed an immunogenicity trial and an expanded safety trial. The timing of a potential submission of a supplemental New Drug Application to the FDA (“Supplemental NDA”) for a smallpox PEP indication for oral TPOXX® will be based on the results of ongoing sample analyses from the immunogenicity trial; the Company is currently targeting a Supplemental NDA submission within the next twelve months. 

     

    Macroeconomic Environment

     

    Future macroeconomic volatility, including changes to and uncertainty regarding tariffs and trade policies, could cause cost increases resulting in an adverse effect on the Company’s operating results. The Company’s supply chain was designed to lessen the impact of macroeconomic volatility such as through development of a U.S. domestic supply chain including U.S. production of API and finished product, and minimal reliance on ex-U.S. components for API and oral TPOXX®.

     

    With respect to IV TPOXX®, tariff activity or other trading restrictions involving the U.S. and Europe may materially increase raw material costs for IV TPOXX® and, in turn, may materially increase IV TPOXX® overall manufacturing costs.

    Procurement Contracts with the U.S. Government

     

    19C BARDA Contract 

     

    On September 10, 2018, the Company entered into a contract with the U.S. Biomedical Advanced Research and Development Authority ("BARDA") pursuant to which SIGA agreed to deliver up to 1,488,000 courses of oral TPOXX® to the Strategic Stockpile, and to manufacture and deliver to the Strategic Stockpile, or store as vendor-managed inventory, up to 212,000 courses of IV TPOXX®. In October 2023, the contract was modified so that a course of IV TPOXX® was redefined within the contract from being 14 vials to being 28 vials; as such, the 19C BARDA Contract currently specifies 106,000 courses of IV TPOXX® (for the same payment amount as originally specified). In addition to the delivery of TPOXX® courses, the contract includes funding from BARDA for a range of activities, including: advanced development of IV TPOXX®, post-marketing activities for oral and IV TPOXX®, development of a pediatric formulation, support for manufacturing activities, and procurement activities. On April 8, 2025, total payments contemplated under the contract with BARDA were increased by $14.3 million to add funding for activities supporting manufacturing. On June 3, 2025, total payments contemplated under the contract with BARDA were increased by $13.2 million in connection with the development of the pediatric formulation of TPOXX®. As of March 31, 2026, the contract with BARDA (as amended, modified, or supplemented from time to time, the "19C BARDA Contract") contemplates up to approximately $630 million of payments, of which approximately $79.2 million of payments are included within the base period of performance, approximately $545.2 million of payments are related to exercised options and up to approximately $5.6 million of payments are currently specified as unexercised options. BARDA may choose in its sole discretion when, or whether, to exercise any of the unexercised options. The period of performance for options is up to ten years from the date of entry into the 19C BARDA Contract and such options could be exercised at any time during the contract term.  

     

    The base period of performance specifies potential payments of approximately $79.2 million for the following activities: payments of approximately $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile; payments of $8.0 million for the manufacture of 10,000 courses (as currently defined within the contract as being 28 vials) of final drug product of IV TPOXX® ("IV FDP"), of which $3.2 million of payments are related to the manufacture of bulk drug substance ("IV BDS") to be used in the manufacture of IV FDP; payments of approximately $59.5 million to fund reimbursed activities; and payments of approximately $0.6 million for supportive procurement activities. As of March 31, 2026, the Company had received $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile, $3.2 million for the manufacture of IV BDS, $4.8 million for the delivery of IV FDP to the Strategic Stockpile and $34.0 million for other base period activities. IV BDS has been used for the manufacture of courses of IV FDP. The $3.2 million received for the completed manufacture of IV BDS had been recorded as deferred revenue as of December 31, 2021, but with the delivery of IV FDP to the Strategic Stockpile during 2022, $2.9 million was recognized as revenue. The remaining $0.3 million of deferred revenue was recognized in the second quarter of 2024 as the IV FDP containing such IV BDS was delivered to and accepted by the Strategic Stockpile.

     

    The options that have been exercised as of March 31, 2026, provide for payments up to approximately $545.2 million. As of March 31, 2026, there are exercised options for the following activities: payments up to $450.2 million for the manufacture and delivery of up to 1.5 million courses of oral TPOXX®; payments up to $76.8 million for the manufacture of courses of IV FDP; payments of up to approximately $3.6 million to fund post-marketing activities for IV TPOXX®; and payments of up to $14.6 million for funding of post-marketing activities for oral TPOXX®. As of March 31, 2026, a cumulative total of $450.2 million of oral TPOXX® has been delivered to the Strategic Stockpile and accepted; a cumulative total of $61.4 million of IV BDS or IV FDP has been either set aside in inventory or delivered to the Strategic Stockpile and accepted (IV BDS that has been set aside has been recorded as deferred revenue and will be recognized as revenue when the IV BDS is manufactured as IV FDP and delivered); and the Company has been cumulatively reimbursed $11.9 million in connection with post-marketing activities for oral and IV TPOXX®. 

     

    Unexercised options specify potential payments up to approximately $5.6 million in total (if all such options are exercised), all of which relates to supportive activities that we currently do not expect to be required.  

     

    The options related to IV TPOXX® were divided into two primary manufacturing steps. There were options related to the manufacture of bulk drug substance (“IV BDS Options”), and there were corresponding options (for the same number of IV courses) for the manufacture of final drug product (“IV FDP Options”). BARDA had the sole discretion to choose to exercise any, all, or none of these options. The 19C BARDA Contract included: three separate IV BDS Options, each providing for the bulk drug substance equivalent of 32,000 courses (as currently defined within the contract) of IV TPOXX®; and three separate IV FDP Options, each providing for 32,000 courses of final drug product of IV TPOXX®. BARDA had the sole discretion as to whether to simultaneously exercise IV BDS Options and IV FDP Options, or whether to exercise options at different points in time (or alternatively, to only exercise the IV BDS Option but not the IV FDP Option). To date, BARDA has exercised all three IV BDS options and all three IV FDP options. The Company estimates that sales of the IV formulation under this contract (under current terms), would have a gross margin (sales less cost of sales, as a percentage of sales) that is less than 40%.

Meridian has limited, non-exclusive rights to advertise, promote, offer for sale and sell oral TPOXX® in the European Economic Area, Australia, Japan, Switzerland, the United Kingdom and the Association of Southeast Asian Nations and its member states (collectively, the “Current Territory”). Meridian also performs non-promotional activities under specified contracts with third parties entered into prior to June 1, 2024, that provide for the sale of oral TPOXX® in the Current Territory. The International Promotion Agreement entitles Meridian to receive a fee equal to a high single digit percentage of collected proceeds (whether collected by Meridian or the Company), net of certain expenses, of sales of oral TPOXX® in the Current Territory in the field of use specified in the International Promotion Agreement. The International Promotion Agreement has a fixed term that expires on May 31, 2026, with no automatic renewal.

     

    Under the terms of the original International Promotion Agreement (“Pre-amendment International Promotion Agreement”), which had an initial term that expired on May 31, 2024, Meridian had been granted exclusive rights to market, advertise, promote, offer for sale, or sell oral TPOXX® in a field of use specified in the International Promotion Agreement in all geographic regions except for the United States (the “Territory”), and Meridian agreed not to commercialize any competing product, as defined in the Pre-amendment International Promotion Agreement, in the specified field of use in the Territory. Under the Pre-amendment International Promotion Agreement, as well as the current International Promotion Agreement, SIGA has always retained ownership, intellectual property, distribution and supply rights and regulatory responsibilities in connection with TPOXX®, and, in the United States market, also retained sales and marketing rights with respect to oral TPOXX®. SIGA’s consent is required prior to the entry by Meridian into any sales arrangement pursuant to the International Promotion Agreement.

     

    Sales to international customers pursuant to the Pre-amendment International Promotion Agreement were invoiced and collected by Meridian, and such collections were remitted, less Meridian’s fees, to the Company under a quarterly process specified in the Pre-amendment International Promotion Agreement; and Meridian was entitled to a specified percentage of the collected proceeds of sales of oral TPOXX®, net of certain expenses, for calendar years in which customer collected amounts net of such expenses were less than or equal to a specified threshold, and to a higher specified percentage of such collected net proceeds for calendar years in which such net collected amounts exceeded the specified threshold. Subsequent to June 1, 2024, only specified procurement contracts for the Current Territory entered into prior to June 1, 2024, continue to involve Meridian invoicing and collecting proceeds, and retaining a fee pursuant to the International Promotion Agreement.

     

    Mpox

     

    In connection with the 2022 response to a global mpox outbreak, a series of observational and randomized, placebo-controlled clinical trials were initiated to assess the safety and efficacy of TPOXX® in participants with mpox. The purpose of these randomized clinical trials was to seek to collect data on the potential benefits of using TPOXX® as an antiviral treatment for active mpox disease. As of March 31, 2026, three of the randomized, placebo-controlled clinical trials reported topline results: a randomized, placebo-controlled clinical trial in the Democratic Republic of the Congo ("DRC") known as PALM 007 (Tecovirimat for Treatment of Monkeypox Virus - NCT05559099), which was funded and sponsored by the National Institutes of Health's (NIH) National Institute of Allergy and Infectious Diseases (NIAID); the Study of Tecovirimat for Human Mpox Virus (STOMP) clinical trial (NCT05534984), which was a randomized, placebo-controlled, double-blind study also sponsored and funded by NIAID to evaluate the safety and efficacy of tecovirimat for the treatment of people with laboratory-confirmed or presumptive mpox disease that included enrollees from Argentina, Brazil, Japan, Mexico, Peru, Thailand, and the United States; and the UNITY clinical trial (Assessment of the Efficacy and Safety of Tecovirimat in Patients With Monkeypox Virus Disease - NCT NCT05597735), which was funded and sponsored by ANRS-Emerging Infectious Diseases, which included enrollees from Switzerland, Brazil, and Argentina. The PALM 007 study did not meet its primary endpoint of a statistically significant improvement in time to lesion resolution within 28 days post-randomization for patients in the DRC with mpox who received TPOXX® compared to patients who received placebo. Some improvement versus placebo was observed in patients receiving TPOXX® whose symptoms began five days or fewer before randomization and patients with severe or grave disease, defined by the World Health Organization (WHO) as having 100 or more skin lesions, however the significance of these data has not been established. Similarly, in the STOMP study, tecovirimat did not meet its primary endpoint of a statistically significant improvement in time to lesion resolution for adults with mild to moderate mpox and a low risk of developing severe disease. Additional analyses of subgroups, secondary and exploratory endpoints is ongoing in each of these studies. Topline data from the UNITY study, which was presented at a medical conference, also showed that the study did not meet its primary endpoint of a statistically significant improvement in time to lesion resolution for patients with mpox who received TPOXX® compared to patients who received placebo. In all three studies, TPOXX® exhibited a safety profile comparable to placebo. These safety results are consistent with prior studies and further support the strong safety profile that has been observed with tecovirimat over the past 15 years.

     

    Two other randomized clinical trials, Platinum-CAN (Canada) and EPOXI (EU), which were started in response to the global mpox outbreak, are closed to enrollment and expected to yield similar results, given the design similarities across these trials.

    Critical Accounting Estimates

     

    The methods, estimates and judgments we use in applying our accounting policies have a significant impact on the results we report in our condensed consolidated financial statements, which we discuss under the heading “Results of Operations” following this section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Information regarding our critical accounting policies and estimates appears in Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations of our 2025 Form 10-K. Our most critical accounting estimate is revenue recognition over time.

     

    Results of Operations

     

    The U.S. tariffs implemented in 2025 and continuing in 2026, and subsequently implemented retaliatory tariffs, did not materially impact our first quarter results. While the long-term effects remain uncertain, we continue to closely monitor the evolving tariff policy environment which presents a mix of impacts, with the potential for higher product and operating costs.

     

    Three Months Ended March 31, 2026 and 2025

     

    For the three months ended March 31, 2026, revenues from product sales and supportive services were $3.5 million. Such revenues include $1.2 million of IV TPOXX® sales to the U.S. Government under the 19C BARDA Contract as well as $2.3 million of reimbursed supportive services in connection with a manufacturing technology transfer. For the three months ended March 31, 2025, revenues from product sales and supportive services were $5.8 million. Such revenues include $5.8 million of oral TPOXX® sales to one international country. 

     

    Revenues from research and development activities for the three months ended March 31, 2026 and 2025, were $2.7 million and $1.2 million, respectively. The revenues for the three months ended March 31, 2026, were earned in connection with performance of research and development activities under the 19C BARDA Contract. The revenues for the three months ended March 31, 2025, were mostly earned in connection with performance of research and development activities under the 19C BARDA Contract. The increase of $1.5 million of revenue is primarily related to an increase in billable activities under the 19C BARDA Contract. 

     

    Cost of sales and supportive services for the three months ended March 31, 2026 and 2025 were $2.9 million and $0.2 million, respectively. Such costs in 2026 were primarily associated with the costs of supportive services in connection with a manufacturing technology transfer, as well as costs for the manufacture and delivery of courses of IV TPOXX® to the U.S. Government under the 19C BARDA Contract. Such costs in 2025 were associated with the manufacture and delivery of courses of oral TPOXX® partially offset by a recovery for inventory previously written off. 

     

    Selling, general and administrative (“SG&A”) expenses for the three months ended March 31, 2026 and 2025 were $4.7 million and $5.7 million, respectively. The decrease of $1.0 million primarily reflects lower professional service fees and lower international business development expenses, partially offset by higher compensation costs.  

     

    Research and development (“R&D”) expenses for the three months ended March 31, 2026 and 2025 were $3.9 million and $3.5 million, respectively, reflecting an increase of approximately $0.4 million. The expense increase is primarily attributable to costs incurred in connection with the EMA referral procedure that was focused on mpox. 

     

    Other income, net for the three months ended March 31, 2026 and 2025 were $1.3 million and $1.7 million, respectively. These amounts reflect interest income earned on cash and cash equivalents.  

     

    For the three months ended March 31, 2026 and 2025, we recorded a pre-tax loss of ($4.0) million and a pre-tax loss of ($0.6) million, respectively, and a corresponding income tax benefit of $0.6 million and $0.2 million, respectively. The effective tax rates during the three months ended March 31, 2026 and 2025 were 14.6% and 28.4%, respectively. Our effective tax rates for the periods ended March 31, 2026 and 2025 differ from the statutory rate primarily as a result of state taxes and non-deductible executive compensation under Internal Revenue Code Section 162(m).

    Liquidity and Capital Resources

     

    As of March 31, 2026, we had $145.6 million in cash and cash equivalents, compared with $155.0 million at December 31, 2025. We believe that our liquidity and capital resources will be sufficient to meet our anticipated requirements for at least the next twelve months from the issuance of these financial statements.

     

    Operating Activities

    We prepare our condensed consolidated statement of cash flows using the indirect method. Under this method, we reconcile net income to cash flows from operating activities by adjusting net income for those items that impact net income but may not result in actual cash receipts or payments during the period. These reconciling items include but are not limited to stock-based compensation, deferred income taxes, and changes in the condensed consolidated balance sheet for working capital from the beginning to the end of the period.

     

    Net cash (used in)/provided by operating activities for the three months ended March 31, 2026 and 2025 was ($8.7) million and $7.1 million, respectively. For the three months ended March 31, 2026, the net cash used in operating activities primarily relates to the use of cash (net of research development revenues) for customary operating activities and inventory. For the three months ended March 31, 2025, the receipt of approximately $20 million from sales of TPOXX® to the U.S. Government and an international customer, all of which was from accounts receivable at December 31, 2024, as well as the receipt of investment income on cash and cash equivalents, was partially offset by the payment of approximately $8 million of income taxes as well as for the use of cash (net of research development revenues) for inventory and customary operating activities.  

     

    Investing Activities

    For the three months ended March 31, 2026, there were no cash-related investing activities; acquisitions of equipment this quarter were not billed as of March 31, 2026. For the three months ended March 31, 2025, there was minimal (less than $25,000) cash-related investing activities. 

     

    Financing Activities

    Cash used in financing activities for the three months ended March 31, 2026 was $0.7 million, which was attributable to the payments of tax obligations in connection with stock issued to employees as well as payments of accrued dividends on vested equity awards. Cash used in financing activities for the three months ended March 31, 2025 was $0.2 million, which was attributable to the payment of tax obligations in connection with stock issued to employees.

     

    Future Cash Requirements

    As of March 31, 2026, we had outstanding purchase orders associated with manufacturing obligations in the aggregate amount of approximately $3.5 million. 

     

    On March 26, 2026, the Board of Directors declared a special cash dividend of $0.60 per share on the common stock of the Company. The special cash dividend was paid on April 23, 2026, to shareholders of record at the close of business on April 7, 2026.

    Recently Issued Accounting Standards

     

    For discussion regarding the impact of accounting standards that were recently issued but are not yet effective, on our condensed consolidated financial statements, see Note 2, Summary of Significant Accounting Policies, to the condensed consolidated financial statements.

     

    Forward-Looking Statements

     

    Certain statements in this Quarterly Report on Form 10-Q contain forward-looking statements that involve risks, uncertainties, and assumptions. All statements contained in this Quarterly Report on Form 10-Q other than statements of historical fact are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

     

    Forward-looking statements include statements regarding our future financial position, business strategy, budgets, projected costs, plans and objectives of management for future operations and statements relating to the progress of SIGA’s development programs and timelines for bringing products to market, delivering products to domestic and international customers, and the enforceability of our procurement contracts, such as the 19C BARDA Contract (the "BARDA Contract"), with the U.S. Biomedical Advanced Research and Development Authority ("BARDA"). The words “may,” “continue,” “estimate,” “intend,” “plan,” “will,” “believe,” “project,” “expect,” “seek,” “anticipate,” “could,” “should,” “target,” “goal,” “potential” and similar expressions may identify forward-looking statements, but the absence of these words does not necessarily mean that a statement is not forward-looking.  Such forward-looking statements are subject to various known and unknown risks and uncertainties, and SIGA cautions you that any forward-looking information provided by or on behalf of SIGA is not a guarantee of future performance. SIGA’s actual results could differ materially from those anticipated by such forward-looking statements due to a number of factors, some of which are beyond SIGA’s control, including, but not limited to, (i) the risk that SIGA may not complete performance under the BARDA Contract on schedule or in accordance with contractual terms, (ii) the risk that SIGA is not able to enter into new contracts to supply TPOXX® to the U.S. Government, (iii) the risk that the nascent international biodefense market does not develop to a degree that allows SIGA to continue to successfully market TPOXX® internationally, (iv) the risk that potential products, including potential alternative uses or formulations of TPOXX® that appear promising to SIGA or its collaborators, cannot be shown to be efficacious or safe in subsequent pre-clinical or clinical trials, (v) the risk that target timing for deliveries of product to customers, and the recognition of related revenues, are delayed or adversely impacted by the actions, or inaction, of contract manufacturing organizations, or other vendors, within the supply chain, or due to coordination activities between the customer and supply chain vendors, (vi) the risk that SIGA or its collaborators will not obtain or maintain appropriate or necessary governmental approvals to market these or other potential products or uses, (vii) the risk that SIGA may not be able to secure or enforce sufficient legal rights in its products, including intellectual property protection, (viii) the risk that any challenge to SIGA’s patent and other property rights, if adversely determined, could affect SIGA’s business and, even if determined favorably, could be costly, (ix) the risk that regulatory requirements applicable to SIGA’s products may result in the need for further or additional testing or documentation that will delay or prevent SIGA from seeking, obtaining, or maintaining needed approvals to market these products, (x) the risk that the volatile and competitive nature of the biotechnology industry may hamper SIGA’s efforts to develop or market its products, (xi) the risk that changes in domestic or foreign economic and market conditions may affect SIGA’s ability to advance its research or may affect its products adversely, (xii) the effect of federal, state, and foreign regulation, including drug regulation and international trade regulation, on SIGA’s businesses, (xiii) the impacts of significant recent shifts in trade policies, including the imposition of tariffs, retaliatory tariff measures, and subsequent modifications or suspensions thereof, and market reactions to such policies and resulting trade disputes, (xiv) the risk of disruptions to SIGA’s supply chain for the manufacture of TPOXX®, causing delays in SIGA’s research and development activities, causing delays or the re-allocation of funding in connection with SIGA’s government contracts, or diverting the attention of government staff overseeing SIGA’s government contracts, (xv) risks associated with actions or uncertainties surrounding the debt ceiling, or the changes in the U.S. administration, and (xvi) the risk that the U.S. or foreign governments' responses (including inaction) to national or global economic conditions or infectious diseases, are ineffective and may adversely affect SIGA’s business, as well as the risks and uncertainties included in Item 1A “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2025 and SIGA's subsequent filings with the Securities and Exchange Commission. SIGA urges investors and security holders to read those documents free of charge at the SEC's website at http://www.sec.gov. All such forward-looking statements are current only as of the date on which such statements were made. SIGA does not undertake any obligation to update publicly any forward-looking statement to reflect events or circumstances after the date on which any such statement is made or to reflect the occurrence of unanticipated events. The information contained on any website referenced in this Form 10-Q is not incorporated by reference into this filing.

     

    Item 3. Quantitative and Qualitative Disclosures About Market Risk

     

    Our investment portfolio includes cash and cash equivalents. Our main investment objective is the preservation of investment capital. We believe that our investment policy is conservative, both in the duration of our investments and the credit quality of the investments we hold. We do not utilize derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments, positions or transactions to manage exposure to interest rate changes. As such, we believe that the securities we hold are subject to market risk and changes in the financial standing of the issuers of such securities, and our interest income is sensitive to changes in the general level of U.S. interest rates.

    Item 4. Controls and Procedures

     

    Evaluation of Disclosure Controls and Procedures

     

    Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2026. The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

     

    Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of March 31, 2026.

     

    Changes in Internal Control over Financial Reporting

     

    There have been no changes in our internal control over financial reporting during the quarter ended March 31, 2026, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

    PART II-OTHER INFORMATION

     

    Item 1. Legal Proceedings

     

    From time to time, we may be involved in a variety of claims, suits, investigations and proceedings arising from the ordinary course of our business, including collections claims, breach of contract claims, labor and employment claims, tax related matters and other matters. Although such claims, suits, investigations and proceedings are inherently uncertain and their results cannot be predicted with certainty, we believe that the resolution of such current pending matters, if any, will not have a material adverse effect on our business, condensed consolidated financial position, results of operations or cash flow. Regardless of the outcome, litigation can have an adverse impact on us because of legal costs, diversion of management resources and other factors.

     

    Item 1A. Risk Factors

     

    Our results of operations and financial condition are subject to numerous risks and uncertainties described in our 2025 Annual Report on Form 10-K for the fiscal year ended December 31, 2025. There have been no material changes to the risk factors disclosed in Part I, Item 1A, "Risk Factors" of our 2025 Form 10-K.
