NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
NOTE 1 – BUSINESS
Tonix Pharmaceuticals (“Tonix” or the “Company”) is a fully-integrated biopharmaceutical company commercializing and developing innovative therapies for central nervous system (“CNS”) disorders, infectious diseases, immunology, and rare diseases. Our portfolio consists of both commercial and development-stage programs.
In August 2025, Tonix received approval from the U.S. Food and Drug Administration (“FDA”) for TONMYA® (cyclobenzaprine HCl sublingual tablets) for the treatment of fibromyalgia. TONMYA, Tonix’s first internally developed product to become FDA approved, was commercially launched by the Company in the United States on November 17, 2025. TONMYA is the first new medicine for fibromyalgia in more than 15 years and is a centrally acting, non-opioid analgesic designed for bedtime administration and long-term use. The Company holds worldwide commercialization rights to TONMYA. In addition to TONMYA, Tonix markets two FDA-approved prescription products for the treatment of acute migraine: Zembrace® SymTouch® (sumatriptan injection) and Tosymra® (sumatriptan nasal spray). Tonix’s commercial platform includes sales, marketing, market access, distribution, and patient support capabilities.
Tonix is advancing a diversified development pipeline generated through internal discovery, in-licensing, acquisitions, and collaborations with academic and non-profit institutions. The Company’s pipeline addresses conditions that span CNS, infectious disease, immunology, and rare disease, with multiple programs in clinical and preclinical development. TONMYA’s proprietary cyclobenzaprine HCl sublingual tablet formulation is referred to as “TNX-102 SL” outside of the fibromyalgia indication. Tonix is exploring the utility of TNX-102 SL in Phase 2 clinical trials for major depressive disorder (MDD) and acute stress disorder (ASD)/acute stress reaction (ASR). TNX-102 SL is being developed to treat ASD/ASR under an Investigator-Initiated investigational new drug application (“IND”) at the University of North Carolina in the ongoing OASIS study funded by a grant they received from the U.S. Department of Defense (“DoD”). A Phase 2 study of TNX-102 SL for MDD is expected to commence mid-2026 under a Tonix IND that has been cleared by FDA.
Tonix’s clinical stage infectious disease portfolio includes monoclonal antibody TNX-4800 (anti Borrelia OspA human monoclonal antibody) for the prevention of Lyme disease in the U.S., for which initiation of an adaptive Phase 2 field study is planned for the first half of 2027, pending FDA agreement. TNX-4800 was licensed from UMass Chan Medical School. Tonix’s clinical-stage immunology development portfolio consists of biologics to address organ transplant rejection, autoimmunity and cancer, including TNX-1500, which is a Phase 2- ready Fc-modified humanized monoclonal antibody targeting CD40-ligand (CD40L or CD154) being developed for the prevention of kidney transplant rejection. Another CNS candidate in clinical development is TNX-1300 (double-mutant cocaine esterase), which is in Phase 2 for the treatment of cocaine intoxication. TNX-1300 has been granted Breakthrough Therapy designation by the FDA and a Phase 2a study was completed. However, because of the challenges of recruiting eligible patients into a subsequent Phase 2 study, the Company terminated that study and intends to meet with the FDA in 2026 to inform the clinical design of its next Phase 2 study. Tonix’s clinical-stage rare disease portfolio includes TNX-2900, intranasal oxytocin potentiated with magnesium, in development for Prader-Willi syndrome and expected to start a Phase 2 study in the first quarter of 2027.
Tonix’s pre-clinical, pre-IND infectious disease portfolio includes
TNX-801 (horsepox, live virus vaccine), as a potential vaccine for mpox and smallpox. We own a facility in Dartmouth, MA that was purpose-built
to manufacture TNX-801 under Good Manufacturing Practices (GMP) to support clinical development and potential commercialization. The GMP
suites were decommissioned in 2024 and may be reactivated on the earlier of 2027 or in the case of a national or international emergency.
Tonix’s pre-IND infectious disease portfolio also includes TNX-4200, which is a small molecule broad-spectrum antiviral agent targeting
CD45 for the prevention or treatment of high lethality infections to improve the medical readiness of military personnel in biological
threat environments. The TNX-4200 program is supported by a $

All intercompany balances and transactions have been eliminated in consolidation.
Going Concern
The accompanying financial statements have been prepared on a basis which
assumes that the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities
and commitments in the normal course of business. The Company has suffered
recurring losses from operations and negative cash flows from operating activities. At March 31, 2026, the Company had working
capital of approximately $

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
These factors raise substantial doubt about the Company’s ability to continue as a going concern. The Company continues to face significant challenges and uncertainties and must obtain additional funding through public and private financing and collaborative arrangements with strategic partners to increase the funds available to fund operations. However, the Company may not be able to raise capital on terms acceptable to the Company, or at all. Without additional funds, it may be forced to delay, scale back or eliminate some of its research and development activities, or other operations and potentially delay product development in an effort to maintain sufficient funds to continue operations. If any of these events occurs, its ability to achieve development and commercialization goals would be adversely affected and the Company may be forced to cease operations. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES
Interim financial statements
The unaudited condensed consolidated interim financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.
The condensed consolidated balance sheet as of December 31, 2025, contained herein has been derived from audited financial statements.
Operating results for the three months ended March 31, 2026 are not necessarily indicative of results that may be expected for the year ending December 31, 2026. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2025, included in the Company’s Annual Report on Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on March 12, 2026.
Risks and uncertainties
The Company’s primary efforts are devoted to commercializing its approved products and conducting research and development of innovative pharmaceutical and biological products to address public health challenges. The Company has experienced net losses and negative cash flows from operations since inception and expects these conditions to continue for the foreseeable future. Further, the Company currently generates revenue from the sale of its commercial products, TONMYA, Zembrace SymTouch® and Tosymra. There is no assurance that the Company will be able to generate sufficient cash flow to fund operations from the sale of its commercial products or products in development, if and when approved. In addition, there can be no assurance that the Company’s research and development will be successfully completed or that any product in development will be approved or commercially viable.
Use of estimates
The preparation of financial statements in accordance with Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include, but are not limited to, impairments, provisions for product returns, coupons, rebates, chargebacks, discounts, allowances, inventory realization, the assumptions used in the fair value of stock-based compensation and other equity instruments, and the percent of completion of research and development contracts.

Segment Information and Concentrations
Operating segments
are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating
decision maker (“CODM”), or decision-making group, in deciding how to allocate resources and in assessing performance.
The Company considers its chief executive officer to be the Company’s CODM. The CODM manages its operations and allocates
resources based on the Company’s consolidated results and therefore operates as
Segment revenue, profit or loss, significant segment expenses and other segment items - The accounting policies of the Company’s single operating and reportable segment are the same as those described in the summary of significant accounting policies. The Company’s method for measuring segment profitability includes net income (loss), which the CODM uses to assess performance and make decisions for resource allocation, consistent with the measurement principles for net income (loss) as reported on the Company’s consolidated statement of operations. The significant expenses regularly reviewed by the CODM are consistent with those reported on the Company’s consolidated statement of operations, and expenses are regularly reviewed on a more disaggregated basis for purposes of assessing segment performance and deciding how to allocate resources. The measure of segment assets is reported on the Company’s consolidated balance sheet.

Cash, Cash Equivalents and Restricted Cash
The Company considers
cash equivalents to be those investments which are highly liquid, readily convertible to cash and have an original maturity of three
months or less when purchased. At March 31, 2026, and March 31, 2025, cash equivalents, which consisted of money market funds,

Accounts Receivable, net
Accounts receivable consists of amounts due from our wholesale and other third-party distributors and pharmacies and have standard payment terms that generally require payment within 30 to 90 days. For certain customers, the accounts receivable for the customer is net of cash discounts, chargebacks and customer rebates. We provide reserves against accounts receivable for estimated losses that may result from a customer’s inability to pay. Amounts determined to be uncollectible are charged or written-off against the reserve.

Concentration of Credit Risk
Financial instruments that potentially subject us to concentrations of credit risk include cash and cash equivalents, and accounts receivable. We attempt to minimize the risks related to cash and cash equivalents by investing in a broad and diverse range of financial instruments, and we have established guidelines related to credit ratings and maturities intended to safeguard principal balances and maintain liquidity. Concentrations of credit risk with respect to receivables, which are typically unsecured, are somewhat mitigated due to the financial stability of our primary customers using our products.
We monitor the financial performance and creditworthiness of our customers so that we can properly assess and respond to changes in their credit profile. We continue to monitor these conditions and assess their possible impact on our business.
Inventories
Inventories are recorded at the lower of cost or net realizable value, with cost determined by the first-in-first-out method. The Company periodically reviews the composition of inventory in order to identify excess, obsolete, slow-moving or otherwise non-saleable items taking into account anticipated future sales compared with quantities on hand, and the remaining shelf life of goods on hand. If non-saleable items are observed and there are no alternate uses for the inventory, the Company records a write-down to net realizable value in the period that the decline in value is first recognized. Although the Company makes every effort to ensure the accuracy of forecasts of future product demand, any significant unanticipated decreases in demand could have a material impact on the carrying value of inventories and reported operating results.
Property and equipment
Property and equipment
are stated at cost, less accumulated depreciation. Depreciation and amortization is calculated using the straight-line method over
the asset’s estimated useful life, which ranges from
Intangible assets, net
Intangible assets deemed
to have finite lives are carried at acquisition-date fair value less accumulated amortization and impairment, if any. Finite-lived
intangible assets consisted of developed technology intangible assets acquired in connection with the acquisition of certain products
from Upsher Smith Laboratories, LLC (“Upsher Smith”) consummated on June 30, 2023. The acquired intangible
assets were amortized using the straight-line method over the estimated useful lives of the respective assets. The Company recorded
a full impairment of its developed technology assets during the second quarter of 2024, therefore there is
Impairment testing of long-lived assets
The Company evaluates long-lived assets for impairment, including property and equipment, finite-lived intangibles assets and operating lease right-to-use assets whenever events or changes in circumstances indicate that their net book value may not be recoverable. When such factors and circumstances exist, the Company compares the projected undiscounted future cash flows associated with the related asset or group of assets over their estimated useful lives against their respective carrying amount. Impairment, if any, is based on the excess of the carrying amount over the fair value, based on market value when available, or discounted expected cash flows, of those assets and is recorded in the period in which the determination is made. For the three months ended March 31, 2026 and 2025, the Company believed that no impairment existed.

Leases
The Company determines if an arrangement is, or contains, a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities, current and operating lease liabilities, noncurrent in the Company’s consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the transition date and subsequent lease commencement dates in determining the present value of lease payments. This is the rate the Company would have to pay if borrowing on a collateralized basis over a similar term to each lease. The operating lease ROU asset excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments made under operating leases is recognized on a straight-line basis over the lease term.
Revenue Recognition
The Company records and recognizes revenue in a manner that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. The Company’s revenues primarily result from contracts with customers, which are generally short-term and have a single performance obligation - the delivery of product.
The Company’s
performance obligation to deliver products is satisfied at the point in time that the goods are received by the customer, which
is when the customer obtains title to and has the risks and rewards of ownership of the products, which is generally upon shipment
or delivery to the customer as stipulated by the terms of the sale agreements. The transaction price is the amount of consideration
to which the Company expects to be entitled in exchange for transferring promised goods to a customer. The consideration promised
in a contract with a customer may include fixed amounts, variable amounts, or both. Our contractual payment terms are typically
Revenues from product sales, net of gross-to-net deductions, are recorded only to the extent a significant reversal in the amount of cumulative revenue recognized is not probable of occurring and when the uncertainty associated with gross-to-net deductions is subsequently resolved. Taxes assessed by governmental authorities and collected from customers are excluded from product sales. Shipping and handling activities are considered to be fulfillment activities and not a separate performance obligation.
Many of the Company’s products sold are subject to a variety of deductions. Revenues are recognized net of estimated rebates and chargebacks, cash discounts, distributor fees, sales return provisions and other related deductions. Deductions to product sales are referred to as gross-to-net deductions and are estimated and recorded in the period in which the related product sales occur. Accruals for these provisions are presented in the consolidated financial statements as reductions to gross sales in determining net sales, and as a contra asset within accounts receivable, net (if settled via credit) and other current liabilities (if paid in cash). Amounts recorded for revenue deductions can result from a complex series of judgements about future events and uncertainties and can rely heavily on estimates and assumptions. The following section briefly describes the nature of the Company’s provisions for variable consideration and how such provisions are estimated:
Chargebacks - The Company sells a portion of its products indirectly through wholesaler distributors, and enters into specific agreements with these indirect customers to establish pricing for the Company’s products, and in-turn, the indirect customers and entities independently purchase these products. Because the price paid by the indirect customers and/or entities is lower than the price paid by the wholesaler, the Company provides a credit, called a chargeback, to the wholesaler for the difference between the contractual price with the indirect customers and the wholesale customer’s purchase price. The Company’s provision for chargebacks is based on expected sell-through levels by the Company’s wholesale customers to the indirect customers and estimated wholesaler inventory levels as well as historical chargeback rates. The Company continually monitors its reserve for chargebacks and adjusts the reserve accordingly when expected chargebacks differ from actual experience.

Rebates - The Company participates in certain government and specific sales rebate programs which provides discounted prescription drugs to qualified recipients, and primarily relate to Medicaid and managed care rebates, pharmacy rebates, Tri-Care rebates and discounts, specialty pharmacy program fees and other governmental rebates or applicable allowances.
| ● | Managed Care Rebates are processed in the quarter following the quarter in which they are earned. The managed care reporting entity submits utilization data after the end of the quarter and the Company processes the payment in accordance with contract terms. All rebates earned but not paid are estimated by the Company according to historical payments trended for market growth assumptions. | |
| ● | Medicaid and State Agency rebates are based upon historical experience of claims submitted by various states. The Company monitors Medicaid legislative changes to determine what impact such legislation may have on the provision for Medicaid rebates. The accrual of State Agency reserves is based on historical payment rates. There is an approximate four to six-month lag from the time of product sale until the rebate is paid. | |
| ● | Tri-Care represents a regionally managed health care program for active duty and retired members, dependents and survivors of the US military. The Tri-Care program supplements health care resources of the US military with civilian health care professionals for greater access and quality healthcare coverage. Through the Tri-Care program, the Company provides pharmaceuticals on a direct customer basis. Prices of pharmaceuticals sold under the Tri-Care program are pre-negotiated and a reserve amount is established to represent the proportionate rebate amount associated with product sales. | |
| ● | Coverage Gap refers to the Medicare prescription drug program and represents specifically the period between the initial Medicare Part D prescription drug program coverage limit and the catastrophic coverage threshold. Applicable pharmaceutical products sold during this coverage gap timeframe are discounted by the Company. Since the nature of the program is that coverage limits are reset at the beginning of the calendar year; the payments escalate each quarter as the participants reach the coverage limit before reaching the catastrophic coverage threshold. The Company has determined that the cost of this reserve will be viewed as an annual cost. Therefore, the accrual will be incurred evenly during the year with quarterly review of the liability based on payment trends and any revision to the projected annual cost. |
Prompt-Pay and other Sales Discounts - The Company provides for prompt pay discounts, which early payments are recorded as a reduction of revenue and as a reduction in the accounts receivable at the time of sale based on the customer’s contracted discount rate. Consumer sales discounts represent programs the Company has in place to reduce costs to the patient. This includes copay buy down and eVoucher programs.
Product Returns - Consistent with industry practice, the customer’s right of return commences typically six months prior to product expiration date and ends one year after product expiration date. Products returned for expiration are reimbursed at current wholesale acquisition cost or indirect contract price. The Company estimates the amount of its product sales that may be returned by the Company’s customers and accrues this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company estimates products returns as a percentage of sales to its customers. The rate is estimated by using historical sales information or appropriate industry average for newly launched products. Adjustments are made to the current provision for returns when data suggests product returns may differ from original estimates.
Research and Development Costs
The Company outsources certain of its research and development efforts and expenses these costs as incurred, including the cost of manufacturing products for testing, as well as licensing fees and costs associated with planning and conducting clinical trials. The value ascribed to patents and other intellectual property acquired in transactions accounted for as an asset acquisition has been expensed as research and development costs, as such property is related to particular research and development projects and had no alternative future uses.
The Company estimates its expenses resulting from its obligations under contracts with vendors, clinical research organizations and consultants and under clinical site agreements in connection with conducting clinical trials. The financial terms of these contracts are subject to negotiations, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided under such contracts. The Company accounts for trial expenses according to the timing of various aspects of the trial. The Company determines accrual estimates taking into account discussion with applicable personnel and outside service providers as to the progress or state of consummation of trials, or the services completed.
During the course of a clinical trial, the Company adjusts its clinical expense recognition if actual results differ from its estimates. The Company makes estimates of its accrued expenses as of each balance sheet date based on the facts and circumstances known to it at that time. The Company’s clinical trial accruals are dependent upon the timely and accurate reporting of contract research organizations and other third-party vendors.

Government Grants
From time to time, the Company may enter into arrangements with governmental entities for the purpose of obtaining funding for research and development activities. The Company is reimbursed for costs incurred that are associated with specified research and development activities included in the grant application approved by the government authority and, in certain arrangements. U.S. GAAP does not have specific accounting standards covering government grants to business entities. The Company applies International Accounting Standards 20 (“IAS 20”), Accounting for Government Grants and Disclosure of Government Assistance by analogy when accounting for government grants. Under IAS 20, government grants are initially recognized when there is reasonable assurance the conditions of the grant will be met and the grant will be received. After initial recognition, government grants received are recognized in earnings in the same period the underlying costs for which the grant is intended to compensate are incurred. The Company classifies government grants received under these arrangements as either a reduction to the related research and development expense or as grant income in the consolidated statements of operations, depending on the fee structure of the arrangement. The Company also applies the disclosure requirements of ASC 832, Government Assistance.
In June 2024, the Company
was awarded a prototype Other Transaction Agreement from the Defense Threat Reduction Agency (“DTRA”), an agency within
the U.S. Department of Defense, to fund the Company’s TNX-4200 program for the development of a small molecule broad-spectrum
antiviral for the prevention or treatment of viral infections to improve the medical readiness of military personnel in biological
threat environments. The DTRA grant provides for payments totaling up to $
Advertising and Promotion Costs
Advertising and promotion costs are expensed
as incurred. The Company recorded advertising and promotion expenses of approximately $
All stock-based payments to employees and to non-employees for their services, including stock options, are measured at fair value on the grant date and recognized in the consolidated statements of operations as compensation expense over the requisite service period. The Company accounts for share-based awards in accordance with the provisions of the Accounting Standards Codification (“ASC”) 718, Compensation – Stock Compensation.
Foreign Currency Translation
Operations of the Company’s Canadian subsidiary, Tonix Pharmaceuticals (Canada), Inc., are conducted in local currency, which represents its functional currency. The U.S. dollar is the functional currency of the other foreign subsidiaries. Balance sheet accounts of the Canadian subsidiary were translated from foreign currency into U.S. dollars at the exchange rate in effect at the balance sheet date and income statement accounts were translated at the average rate of exchange prevailing during the period. Translation adjustments resulting from this process were included in accumulated other comprehensive loss on the consolidated balance sheets.
Comprehensive Income (Loss)
Comprehensive income (loss) is defined as the change in equity of a business during a period from transactions and other events and circumstances from non-owners sources. It includes all changes in equity during a period except those resulting from investments by owners and distributions to owners. Other comprehensive income (loss) represents foreign currency translation adjustments.
Income Taxes
Deferred income tax assets and liabilities are determined based on the estimated future tax effects of net operating loss and credit carryforwards and temporary differences between the tax basis of assets and liabilities and their respective financial reporting amounts measured at the current enacted tax rates. The Company records a valuation allowance on its deferred income tax assets if it is not more likely than not that these deferred income tax assets will be realized.
The Company recognizes a tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. As of March 31, 2026, the Company has not recorded any unrecognized tax benefits. The Company’s policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.

The computation of basic and diluted loss per share for the three months ended March 31, 2026 and 2025 excludes potentially dilutive securities when their inclusion would be anti-dilutive, or if their exercise prices were greater than the average market price of the common stock during the period. Prefunded warrants are assumed exercised on date of issuance and are included in the basic earnings per share (“EPS”) calculation thus excluded from the table below.
All warrants (See Note 14) issued participate on a one-for-one basis with common stock in the distribution of dividends, if and when declared by the Board of Directors, on the Company’s common stock. For purposes of computing EPS, these warrants are considered to participate with common stock in earnings of the Company. Therefore, the Company calculates basic and diluted EPS using the two-class method. Under the two-class method, net income for the period is allocated between common stockholders and participating securities according to dividends declared and participation rights in undistributed earnings. No income was allocated to the warrants for the three months ended March 31, 2026 and 2025, as results of operations were a loss for the periods.

Recently Adopted Accounting Pronouncements
In July 2025, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides guidance for estimating credit losses under the current expected credit losses (CECL) model for current accounts receivable and current contract assets arising from transactions accounted for under Accounting Standards Codification 606. The Company has adopted this ASU on a prospective basis, and it did not have a material impact on its consolidated financial statements and related disclosures.
Recently Issued Accounting Pronouncements
In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832). The amendments in this ASU establish the accounting for a government grant received by a business entity, including guidance for (1) a grant related to an asset and (2) a grant related to income. The amendments in this ASU are effective annual reporting periods beginning after December 15, 2028, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2025-10 on its consolidated financial statements.
In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU amends the existing standard to remove all references to software development project stages and requires entities to start capitalizing software costs when both of the following occur: (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. This ASU is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years, with early adoption permitted as of the beginning of a fiscal year. The amendments can be applied prospectively, retrospectively, or via a modified prospective transition method. The Company is evaluating the impact of adoption on its consolidated financial statements and related disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, to improve transparency in financial reporting by requiring entities to present more detailed information about the nature of expenses included within the Income Statement. The guidance will first be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted.

On May 1, 2020, the Company’s stockholders approved the Tonix Pharmaceuticals Holding Corp. Amended and Restated 2020 Stock Incentive Plan (“Amended and Restated 2020 Plan”).
Under the terms of the Amended and Restated 2020 Plan, the Company may issue (1) stock options (incentive and nonstatutory), (2) restricted stock, (3) stock appreciation rights (“SARs”), (4) RSUs, (5) other stock-based awards, and (6) cash-based awards.

On May 8, 2025, the Company's stockholders approved the addition of shares to the Company's Amended and Restated 2020 Plan.
The Board of Directors determines the exercise price, vesting and expiration period of the grants under the Amended and Restated 2020 Plan. However, the exercise price of an incentive stock option may not be less than % of fair value of the common stock at the date of the grant for a 10% or more shareholder and % of fair value for a grantee who is not a 10% shareholder.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This Management’s Discussion and Analysis of Financial Condition and Results of Operations includes a number of forward-looking statements that reflect Management’s current views with respect to future events and financial performance. You can identify these statements by forward-looking words such as “may” “will,” “expect,” “anticipate,” “believe,” “estimate” and “continue,” or similar words. Those statements include statements regarding the intent, belief or current expectations of us and members of our management team as well as the assumptions on which such statements are based. Prospective investors are cautioned that any such forward-looking statements are not guarantees of future performance and involve risk and uncertainties, and that actual results may differ materially from those contemplated by such forward-looking statements.
Readers are urged to carefully review and consider the various disclosures made by us in this report and in our other reports filed with the Securities and Exchange Commission. Important factors known to us could cause actual results to differ materially from those in forward-looking statements. We undertake no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes in the future operating results over time. We believe that our assumptions are based upon reasonable data derived from and known about our business and operations. No assurances are made that actual results of operations or the results of our future activities will not differ materially from our assumptions. Factors that could cause differences include, but are not limited to: our need for additional financing; risks related to the failure to obtain FDA clearances or approvals and noncompliance with FDA regulations; risks related to the failure to successfully market any of our products; risks related to the timing and progress of clinical development of our product candidates; uncertainties of patent protection and litigation; uncertainties of government or third party payor reimbursement; limited research and development efforts and dependence upon third parties; and substantial competition.
Business Overview
We are a fully-integrated biopharmaceutical company commercializing and developing innovative therapies for central nervous system (“CNS”) disorders, infectious diseases, immunology, and rare diseases. Our portfolio consists of both commercial and development-stage programs.
In August 2025, we received approval from the FDA for TONMYA® (cyclobenzaprine HCl sublingual tablets) for the treatment of fibromyalgia. TONMYA, our first internally developed product to become FDA approved, was commercially launched by us in the United States on November 17, 2025. TONMYA is the first new medicine for fibromyalgia in more than 15 years and is a centrally acting, non-opioid analgesic designed for bedtime administration and long-term use. We hold worldwide commercialization rights to TONMYA. In addition to TONMYA, we market two FDA-approved prescription products for the treatment of acute migraine: Zembrace® SymTouch® (sumatriptan injection) and Tosymra® (sumatriptan nasal spray). Our commercial platform includes sales, marketing, market access, distribution, and patient support capabilities. We are advancing a diversified development pipeline generated through internal discovery, in-licensing, acquisitions, and collaborations with academic and non-profit institutions. Our pipeline addresses conditions that span CNS, infectious disease, immunology, and rare disease, with multiple programs in clinical and preclinical development. TONMYA’s proprietary cyclobenzaprine HCl sublingual tablet formulation is referred to as “TNX-102 SL” outside of the fibromyalgia indication. We are exploring the utility of TNX-102 SL in Phase 2 clinical trials for major depressive disorder (MDD) and acute stress disorder (ASD)/acute stress reaction (ASR). TNX-102 SL is being developed to treat ASD/ASR under an Investigator-Initiated investigational new drug application (“IND”) at the University of North Carolina in the ongoing OASIS study funded by a grant they received from the U.S. Department of Defense (“DoD”). A Phase 2 study of TNX-102 SL for MDD is expected to commence mid-2026 under a Tonix IND that has been cleared by FDA.
Our clinical stage infectious disease portfolio includes monoclonal antibody TNX-4800 (anti-Borrelia OspA human monoclonal antibody) for the prevention of Lyme disease in the U.S., for which initiation of an adaptive Phase 2 field study is planned for the first half of 2027, pending FDA agreement. TNX-4800 was licensed from UMASS Chan Medical School. Our clinical-stage immunology development portfolio consists of biologics to address organ transplant rejection and autoimmunity, including TNX-1500, which is a Phase 2-ready Fc-modified humanized monoclonal antibody targeting CD40-ligand (CD40L or CD154) being developed for the prevention of kidney transplant rejection. Another CNS candidate in clinical development is TNX-1300 (double-mutant cocaine esterase), which is in Phase 2 for the treatment of cocaine intoxication. TNX-1300 has been granted Breakthrough Therapy designation by the FDA and a Phase 2a study was completed. However, because of the challenges of recruiting eligible patients into a subsequent Phase 2 study, we terminated that study and intend to meet with the FDA in 2026 to inform the clinical design of our next Phase 2 study. Our clinical-stage rare disease portfolio includes TNX-2900, intranasal oxytocin potentiated with magnesium, in development for Prader-Willi syndrome and expected to start a Phase 2 study in the first quarter of 2027. Our pre-clinical, pre-IND infectious disease portfolio includes TNX-801 (horsepox, live virus vaccine), as a potential vaccine for mpox and smallpox. We own a facility in Dartmouth, MA that was purpose-built to manufacture TNX-801 under Good Manufacturing Practices (GMP) to support clinical development and potential commercialization. The facility was decommissioned in 2024 and may be reactivated on the earlier of 2027 or in the case of a national or international emergency. Our pre-IND infectious disease portfolio also includes TNX-4200, which is a small molecule broad-spectrum antiviral agent targeting CD45 for the prevention or treatment of high lethality infections to improve the medical readiness of military personnel in biological threat environments. The TNX-4200 program is supported by a $34 million contract over five years from the U.S. DoD’s Defense Threat Reduction Agency (DTRA). We own and operate a state-of-the art research facility in Frederick, Maryland that supports this research. Our pre-IND pre-clinical immunology portfolio includes TNX-1700, which is a fusion protein of TFF2 and albumin is in preclinical development for the treatment of gastric and colorectal cancer in combination with PD-1 blockade in collaboration with Columbia University. Finally, our pre-clinical, pre-IND CNS portfolio also includes TNX-4900, a highly selective small-molecule Sigma-1 receptor (“S1R”) antagonist for neuropathic pain licensed from Rutgers University.
Our product candidates in development are investigational new drugs or biologics and have not been approved for any indication.

Results of Operations
We anticipate that our results of operations will fluctuate for the foreseeable future due to several factors, such as the sale of our commercialized assets, progress of our research and development efforts and the timing and outcome of regulatory submissions. Due to these uncertainties, accurate predictions of future operations are difficult or impossible to make.

Cost of Sales. Cost of sales recognized for the three months ended March 31, 2026 and 2025, was $1.6 million and $0.9 million, respectively. The increase is predominantly due to the launch of Tonmya in November 2025.
Research and Development Expenses. Research and development expenses for the three months ended March 31, 2026, were $18.2 million, an increase of $10.8 million, or 146%, from $7.4 million for the three months ended March 31, 2025. The increase is predominately due to increased clinical expenses of $0.8 million, non-clinical expenses of $0.4 million, and manufacturing expenses of $6.6 million as a result of pipeline prioritization period over period, and employee-related expenses of $2.5 million due to an increased workforce predominately as a result of the launch of TONMYA in November 2025.
The table below summarizes our direct research and development expenses for our product candidates and development platform for the three months ended March 31, 2026, and 2025.

Our direct research and development expenses consist principally of external costs for clinical, nonclinical and manufacturing, such as fees paid to contractors, consultants and contract research organizations in connection with our development work. Included in “Internal Staffing, Overhead and Other” is overhead, supplies, research and development employee costs (including stock option expenses), travel, regulatory and legal.
26
Selling, General and Administrative Expenses. General and administrative expenses for the three months ended March 31, 2026, were $28.6 million, an increase of $18.5 million, or 183%, from $10.1 million incurred in the three months ended March 31, 2025. The increase is primarily due to an increase in sales and marketing of $11.3 million, an increase in employee related expenses of $3.9 million, and increased professional fees of $2.7 million, predominately as a result of the launch of TONMYA in November 2025.
Net Loss. As a result of the forgoing, the net loss for the three months ended March 31, 2026, was $40.2 million, compared to a net loss of $16.8 million for the three months ended March 31, 2025, an increase of $23.4 million or 139%. The increase in loss is predominately due to increased spending on research and development and selling, general and administrative expenses.
License Agreement
On June 26, 2025, we obtained an exclusive worldwide license from the University of Massachusetts (“UMass”) Chan Medical School for the development of TNX-4800 (formerly known as mAb 2217LS). As of December 31, 2025, other than an upfront fee of $1.3 million, no payments have been accrued or paid in relation to this agreement.
Asset Purchase Agreements
On June 23, 2023, we entered into an asset purchase agreement with Upsher Smith for the acquisition of certain assets related to Zembrace and Tosymra.
We have assumed certain obligations of Upsher Smith, including the payment of quarterly royalty payments on annual net sales from the Business in the U.S. as follows: for Tosymra, 4% for net sales of $0 to $30 million, 7% of net sales of $30 to $75 million; 9% for net sales of $75 to $100 million; 12% for net sales of $100 to $150 million; and 15% for net sales greater than $150 million. Royalty payments with respect to Tosymra are payable until the expiration or termination of the product’s Orange Book listed patent(s) with respect to the United States or, outside the United States, the expiration of the last valid claim covering the product in the relevant country of the territory. For Zembrace, royalty payments on annual net sales in the U.S. are 3% for net sales of $0 to $30 million, 6% of net sales of $30 to $75 million; 12% for net sales of $75 to $100 million; 16% for net sales of greater than $100 million. Such royalty payments were payable until July 19, 2025. Upon the entry of a generic version of the relevant product, the applicable royalty rates will be reduced by 90% for Zembrace, and by 66.7% for Tosymra.
In addition, we have assumed the obligation to pay an additional 3% royalty on net sales of Tosymra, plus an additional 3% if a patent containing certain claims related to Tosymra issues in the U.S., for 15 years from the first commercial sale of Tosymra in the applicable country or for as long as the manufacture, use or sale of Tosymra in such country is covered by a valid claim of a licensed patent, and up to $15 million per Tosymra product on the achievement of sales milestones ranging from $250 million to $1 billion in annual worldwide net sales.
Liquidity and Capital Resources
As of March 31, 2026, we had working capital of $177.5 million, comprised primarily of cash and cash equivalents of $185.5 million, accounts receivable, net of $8.8 million, inventory of $3.6 million, and prepaid expenses and other of $9.2 million, offset by $9.7 million of accounts payable, $19.8 million of accrued expenses and other current liabilities, and $0.2 million of lease liabilities, short term. A significant portion of the accounts payable and accrued expenses are due to work performed in relation to our clinical programs, and accruals for gross to net deductions related to our commercial products.
The following table provides a summary of operating, investing and financing cash flows for the quarters ended March 31, 2026, and 2025, respectively (in thousands):
| March 31, | ||||||||
| 2026 | 2025 | |||||||
| Net cash used in operating activities | $ | (42,318 | ) | $ | (16,579 | ) | ||
| Net cash used in investing activities | (1,692 | ) | (6 | ) | ||||
| Net cash provided by (used in) financing activities | 20,205 | 49,533 | ||||||
For the three months ended March 31, 2026, and 2025, we used approximately $42.3 million and $16.6 million in operating activities, respectively, which represents cash outlays for research and development and selling, general and administrative expenses in such periods. For the three months ended March 31, 2026, net cash provided by financing activities was $20.2 million, predominately from the proceeds from the sale of our common stock. For the three months ended March 31, 2025, net cash provided by financing activities was $49.5 million, predominately from the proceeds from the sale of our common stock of $62.2 million, offset by the repayment of the term loan of $9.7 million and repurchase of our common stock of $3.0 million. Cash used by investing activities for the three months ended March 31, 2026, and 2025, was $1.7 million and $6,000 respectively, related to the purchase of property and equipment. The increase is predominately due to more laboratory equipment purchases.
We believe that our cash resources at March 31, 2026, and the net proceeds of $22.6 million that we raised from equity offerings in the second quarter of 2026 (See Note 12) will meet our planned operating and capital expenditure requirements into early second quarter of 2027, but will not extend to 12 months from the issuance of these financial statements.
We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidly than currently expected due to changes we may make in our research and development spending plans. These factors raise substantial doubt about our ability to continue as a going concern for the one-year period from the date of filing of this Form 10-Q. We must obtain additional funding through public or private financing or collaborative arrangements with strategic partners to increase the funds available to fund operations. Without additional funds, we may be forced to delay, scale back or eliminate some of our research and development activities, or other operations and potentially delay product development to provide sufficient funds to continue our operations. If any of these events occur, our ability to achieve our development and commercialization goals would be adversely affected and we may be forced to cease operations.
27
Future Liquidity Requirements
We expect to incur losses from operations for the near future. We expect to incur increasing research and development expenses, including expenses related to additional clinical trials and the build out of our research and development operations and manufacturing. We will not have enough resources to meet our operating requirements for the one-year period from filing date of this report.
Our future capital requirements will depend on a number of factors, including the availability of financing, the timing and outcome of regulatory approvals, the progress of our research and development of product candidates, the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims and other intellectual property rights, the status of competitive products, and our success in developing markets for our product candidates.
We will need to obtain additional capital in order to fund future research and development activities. Future financing may include the issuance of equity or debt securities, obtaining credit facilities, or other financing mechanisms. Even if we are able to raise the funds required, it is possible that we could incur unexpected costs and expenses, fail to collect significant amounts owed to us, or experience unexpected cash requirements that would force us to seek alternative financing. Furthermore, if we issue additional equity or debt securities, shareholders may experience additional dilution or the new equity securities may have rights, preferences or privileges senior to those of existing holders of our common stock.
If additional financing is not available or is not available on acceptable terms, we may be required to delay, reduce the scope of or eliminate our research and development programs, reduce our commercialization efforts or obtain funds through arrangements with collaborative partners or others that may require us to relinquish rights to certain product candidates that we might otherwise seek to develop or commercialize independently.
2025 Lincoln Park Transaction
On June 11, 2025, we entered into a purchase agreement (the “2025 Purchase Agreement”) and a registration rights agreement (the “2025 Registration Rights Agreement”) with Lincoln Park. Pursuant to the terms of the 2025 Purchase Agreement, Lincoln Park has agreed to purchase up to $75,000,000 of our common stock (subject to certain limitations) from time to time during the term of the 2025 Purchase Agreement. Pursuant to the terms of the 2025 Registration Rights Agreement, we filed with the SEC a registration statement to register for resale under the Securities Act the shares that have been or may be issued to Lincoln Park under the 2025 Purchase Agreement.
Pursuant to the terms of the 2025 Purchase Agreement, at the time we signed the 2025 Purchase Agreement and the 2025 Registration Rights Agreement, we issued 48,708 shares of common stock to Lincoln Park as consideration for its commitment to purchase shares of our common stock under the 2025 Purchase Agreement. The commitment shares were valued at $1.8 million and recorded as an addition to equity for the issuance of the common stock and treated as other expense, net on the consolidated statement of operations under the 2025 Purchase Agreement. No shares were sold during the quarter ended March 31, 2026, under the 2025 Purchase Agreement.
We evaluated the 2025 Purchase Agreement under ASC 815-40 Derivatives and Hedging-Contracts on an Entity’s Own Equity as it represents the right to require Lincoln Park to purchase shares of common stock in the future, similar to a put option. We concluded that the 2025 Purchase Agreement represents a freestanding derivative instrument that does not qualify for equity classification and therefore requires fair value accounting. We analyzed the terms of the contract and concluded that the derivative instrument had insignificant value as of March 31, 2026 and December 31, 2025.
2025 At-the-Market Offering
On June 11, 2025, we entered into a Sales Agreement (the “2025 Sales Agreement”), with A.G.P./Alliance Global Partners (“AGP”) pursuant to which we may issue and sell, from time to time, shares of common stock having an aggregate offering price of up to $400.0 million in sales. AGP is sales agent under the ATM and paid a 3% commission on each sale under the 2025 Sales Agreement. Our common stock is sold at prevailing market prices at the time of the sale, and, as a result, prices will vary. During the quarter ended March 31, 2026, we sold 1.4 million shares of common stock under the 2025 Sales Agreement, for net proceeds of approximately $20.1 million. Subsequent to March 31, 2026, we sold 1.7 million shares of common stock under the 2025 Sales Agreement, for net proceeds of approximately $22.6 million.
2024 At-the-Market Offering
On July 30, 2024, we entered into a Sales Agreement with AGP pursuant to which we may issue and sell, from time to time, shares of our common stock having an aggregate offering price of up to $250.0 million in the ATM. AGP will act as sales agent and will be paid a 3% commission on each sale under the Sales Agreement. Our common stock will be sold at prevailing market prices at the time of the sale, and, as a result, prices will vary. During the three months ended March 31, 2025, we sold approximately 2.7 million shares of common stock under the Sales Agreement, for net proceeds of approximately $59.8 million.
28
Share Repurchase Program
In September 2024, the Board of Directors approved a 2024 share repurchase program pursuant to which we may repurchase up to $10.0 million in value of its outstanding common stock from time to time on the open market and in privately negotiated transactions subject to market conditions, share price and other factors. During the three months ended March 31, 2025, the Company repurchased 250,000 of shares of its common stock outstanding under the 2024 share repurchase at prices ranging from $9.98 to $14.33 per share for a gross aggregate cost of approximately $3.0 million. No shares of common stock were repurchased during the three months ended March 31, 2026.
The timing and amount of any shares repurchased will be determined based on our evaluation of market conditions and other factors and the share repurchase program may be discontinued or suspended at any time. Repurchases will be made in accordance with the rules and regulations promulgated by the Securities and Exchange Commission and certain other legal requirements to which the Company may be subject. Repurchases may be made, in part, under a Rule 10b5-1 plan, which allows stock repurchases when the Company might otherwise be precluded from doing so.
Stock Compensation
Stock Incentive Plans
On May 1, 2020, our stockholders approved the Tonix Pharmaceuticals Holding Corp. Amended and Restated 2020 Stock Incentive Plan (“Amended and Restated 2020 Plan”).
Under the terms of the Amended and Restated 2020 Plan, we may issue (1) stock options (incentive and nonstatutory), (2) restricted stock, (3) stock appreciation rights (“SARs”), (4) restricted stock units, (5) other stock-based awards, and (6) cash-based awards. The Amended and Restated 2020 Plan initially provided for the issuance of up to 50,000 shares of common stock, which amount will be increased to the extent that awards granted under the Plans are forfeited, expire or are settled for cash (except as otherwise provided in the Amended and Restated 2020 Plan). In addition, the Amended and Restated 2020 Plan contains an “evergreen provision” providing for an annual increase in the number of shares of our common stock available for issuance under the Amended and Restated 2020 Plan on January 1 of each year for a period of ten years, commencing on January 1, 2021 and ending on (and including) January 1, 2030, in an amount equal to the difference between (x) twenty percent (20%) of the total number of shares of common stock outstanding on December 31st of the preceding calendar year, and (y) the total number of shares of common stock reserved under the Amended and Restated 2020 Plan on December 31st of such preceding calendar year (including shares subject to outstanding awards, issued pursuant to awards or available for future awards). The Board of Directors determines the exercise price, vesting and expiration period of the grants under the Amended and Restated 2020 Plan. However, the exercise price of an incentive stock option may not be less than 110% of fair value of the common stock at the date of the grant for a 10% or more shareholder and 100% of fair value for a grantee who is not a 10% shareholder. The fair value of the common stock is determined based on quoted market price or in absence of such quoted market price, by the Board of Directors in good faith. Additionally, the expiration period of grants under the Amended and Restated 2020 Plan may not be more than ten years. As of March 31, 2026, there were 425,649 options available for future grants under the Amended and Restated 2020 Plan.
On May 8, 2025, the Company's stockholders approved the addition of 1,000,000 shares to the Company's Amended and Restated 2020 Plan.
29
We measure the fair value of stock options on the date of grant, based on the Black Scholes option pricing model using certain assumptions discussed below, and the closing market price of the Company’s common stock on the date of the grant. The fair value of the award is measured on the grant date. One-third of most stock options granted pursuant to the Plans vest 12 months from the date of grant and 1/36th each month thereafter for 24 months and expire ten years from the date of grant. In addition, the Company issues options to directors which vest over a one-year period. The Company also issues premium options to executive officers which have an exercise price greater than the grant date fair value and has issued performance-based options which vest when target parameters are met or probable of being met, subject in each case to a one year minimum service period prior to vesting. Stock-based compensation expense related to awards is amortized over the applicable service period using the straight-line method.
The risk-free interest rate is based on the yield of Daily U.S. Treasury Yield Curve Rates with terms equal to the expected term of the options as of the grant date. The expected term of options is determined using the simplified method, as provided in an SEC Staff Accounting Bulletin, and the expected stock price volatility is based on the Company’s historical stock price volatility.
The weighted average fair value of options granted for the three-month periods ended March 31, 2026 and 2025 was $13.4 and $7.55 per share, respectively.
Stock-based compensation expense relating to options granted of $1.9 million, of which $1.3 million and $0.6 million, related to Selling, General and Administration and Research and Development, respectively, was recognized for the three months ended March 31, 2026.
Stock-based compensation expense relating to options granted of $0.9 million, of which $0.6 million and $0.3 million, related to Selling, General and Administration and Research and Development, respectively, was recognized for the three months ended March 31, 2025.
As of March 31, 2026, we had approximately $23.3 million of total unrecognized compensation cost related to non-vested awards granted under the Plans, which the Company expects to recognize over a weighted average period of 3.36 years.
Employee Stock Purchase Plan
On May 5, 2023, our stockholders approved the Tonix Pharmaceuticals Holdings Corp. 2023 Employee Stock Purchase Plan. (the “2023 ESPP”), which was replaced by the Tonix Pharmaceuticals Holdings Corp. 2025 Employee Stock Purchase Plan (the “2025 ESPP”, and together with the 2023 ESPP, the “ESPP Plans”), which was approved by our stockholders on May 8, 2025.
The 2025 ESPP allows eligible employees to purchase up to an aggregate of 2,000,000 shares of the Company's common stock. Under the 2025 ESPP, on the first day of each offering period, each eligible employee for that offering period has the option to enroll for that offering period, which allows the eligible employees to purchase shares of the Company's common stock at the end of the offering period. Each offering period under the 2025 ESPP is for six months, which can be modified from time to time. Subject to limitations, each participant will be permitted to purchase a number of shares determined by dividing the employee's accumulated payroll deductions for the offering period by the applicable purchase price, which is equal to 85 percent of the fair market value of our common stock at the beginning or end of each offering period, whichever is less. A participant must designate in his or her enrollment package the percentage (if any) of compensation to be deducted during that offering period for the purchase of stock under the 2025 ESPP, subject to the statutory limit under the Code.
The 2023 ESPP allows eligible employees to purchase up to an aggregate of 250 shares of the Company’s common stock. Under the 2023 ESPP, on the first day of each offering period, each eligible employee for that offering period has the option to enroll for that offering period, which allows the eligible employees to purchase shares of the Company’s common stock at the end of the offering period. Each offering period under the 2023 ESPP is for six months, which can be modified from time-to-time. Subject to limitations, each participant will be permitted to purchase a number of shares determined by dividing the employee’s accumulated payroll deductions for the offering period by the applicable purchase price, which is equal to 85 percent of the fair market value of our common stock at the beginning or end of each offering period, whichever is less. A participant must designate in his or her enrollment package the percentage (if any) of compensation to be deducted during that offering period for the purchase of stock under the 2023 ESPP, subject to the statutory limit under the Code. As of March 31, 2026, 159 shares were available for future sales under the 2023 ESPP and 1,994,117 shares were available under the 2025 ESPP.
The ESPP Plans are considered compensatory plans with the related compensation cost expensed over the six-month offering period. For the three months ended March 31, 2026 and 2025, $0.1 million and $0, respectively, were expensed. As of December 31, 2025, approximately $90,000 of employee payroll deductions had accumulated and had been recorded in accrued expenses. In January 2026, 5,883 shares that were purchased as of December 31, 2025, under the 2025 ESPP, were issued.

Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.
We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.
Revenue Recognition. Our gross product revenues are subject to a variety of deductions, which generally are estimated and recorded in the same period that the revenues are recognized. Such variable consideration represents chargebacks, rebates, prompt pay and other sales discounts, and product returns. These deductions represent estimates of the related obligations and, as such, knowledge and judgment are required when estimating the impact of these revenue deductions on gross sales for a reporting period. Adjustments to these estimates to reflect actual results or updated expectations will be assessed each period. If any of our ratios, factors, assessments, experiences, or judgments are not indicative or accurate estimates of our future experience, our results could be materially affected. The potential of our estimates to vary differs by program, product, type of customer and geographic location. In addition, estimates associated with U.S. Medicare and Medicaid governmental rebate programs are at risk for material adjustment because of the extensive time delay.
Research and Development. We outsource certain of our research and development efforts and expense the related costs as incurred, including the cost of manufacturing product for testing, licensing fees and costs associated with planning and conducting clinical trials. The value ascribed to patents and other intellectual property acquired was expensed as research and development costs, as it related to particular research and development projects and had no alternative future uses.
31
We estimate our research and development accrued expenses. Our clinical trial accrual process is designed to account for expenses resulting from our obligations under contracts with vendors, consultants and clinical research organizations and clinical site agreements in connection with conducting clinical trials. The financial terms of these contracts are subject to negotiations, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided to us under such contracts. We account for trial expenses according to the progress of the trial as measured by participant progression and the timing of various aspects of the trial. We determine accrual estimates that take into account discussions with applicable personnel and outside service providers as to the progress or state of completion of trials, or the services completed. During the course of a clinical trial, we adjust our clinical expense recognition if actual results differ from our estimates. We make estimates of our accrued expenses as of each balance sheet date based on the facts and circumstances known to us at that time. Our clinical trial accruals and prepaid assets are dependent upon the timely and accurate reporting of contract research organizations and other third-party vendors.
Stock-Based Compensation. All stock-based payments to employees and to nonemployee directors for their services as directors consisted of grants of restricted stock and stock options, which are measured at fair value on the grant date and recognized in the consolidated statements of operations as compensation expense over the relevant vesting period. In addition, for awards that vest immediately and are nonforfeitable, the measurement date is the date the award is issued.
Derivative Instruments and Warrant Liabilities. The Company evaluates all of its financial instruments, including issued warrants to purchase common stock under ASC 815 – Derivatives and Hedging, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the consolidated statements of operations. The Company uses the Black-Scholes option pricing model to value the derivative instruments at inception and subsequent valuation dates, which is adjusted for instrument-specific terms as applicable.
From time to time, certain equity-linked instruments may be classified as derivative liabilities due to the Company having insufficient authorized shares to fully settle the equity-linked financial instruments in shares. In such a case, the Company has adopted a sequencing approach under ASC 815-40, Derivatives and Hedging - Contracts in Entity’s Own Equity to determine the classification of its contracts at issuance and at each subsequent reporting date. If reclassification of contracts between equity and assets or liabilities is necessary, the Company first allocates remaining authorized shares to equity on the basis of the earliest issuance date of potentially dilutive instruments, with the earliest issuance date receiving the first allocation of shares. In the event of identical issuance dates, shares are then allocated to equity beginning with instruments with the latest maturity date first.
Other than contractual obligations incurred in the normal course of business, we do not have any off-balance sheet financing arrangements or liabilities, guarantee contracts, retain or contingent interests in transferred assets or any obligation arising out of a material variable interest in an unconsolidated entity.

Recently Adopted Accounting Pronouncements
In July 2025, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides guidance for estimating credit losses under the current expected credit losses (CECL) model for current accounts receivable and current contract assets arising from transactions accounted for under Accounting Standards Codification 606. We have adopted this ASU on a prospective basis, and it did not have a material impact on our consolidated financial statements and related disclosures.
Recently Issued Accounting Pronouncements
In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832). The amendments in this ASU establish the accounting for a government grant received by a business entity, including guidance for (1) a grant related to an asset and (2) a grant related to income. The amendments in this ASU are effective annual reporting periods beginning after December 15, 2028, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2025-10 on our consolidated financial statements.
In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU amends the existing standard to remove all references to software development project stages and requires entities to start capitalizing software costs when both of the following occur: (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. This ASU is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years, with early adoption permitted as of the beginning of a fiscal year. The amendments can be applied prospectively, retrospectively, or via a modified prospective transition method. We are evaluating the impact of adoption on our consolidated financial statements and related disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures, to improve transparency in financial reporting by requiring entities to present more detailed information about the nature of expenses included within the Income Statement. The guidance will first be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is in the process of assessing the impact of ASU 2024-03 on our financial statements.
ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Not applicable.
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 pursuant to Rule 13a-15 under the Securities Exchange Act of 1934 as of the end of the period covered by this Quarterly Report on Form 10-Q. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.
33
Based on our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2026, our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Changes in internal control over financial reporting.
During the first quarter of 2026, the Company completed the implementation of a new ERP system. Our new ERP system is intended to provide us with enhanced transactional processing, security and management tools, and is an important component of our system of disclosure controls and procedures. We modified and removed certain existing internal controls, as well as implemented new controls and procedures impacted by the implementation of the new ERP system. We will continue to monitor and evaluate the operating effectiveness of the related controls during subsequent periods. Except for the implementation of the new ERP system, there were no other changes in the internal control over financial reporting of the Company during the first quarter of 2026 that materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
