Dogwood Therapeutics, Inc.

1. Background and Organization

Dogwood Therapeutics, Inc. (the “Company”), formerly known as Virios Therapeutics, Inc., was incorporated under the laws of the State of Delaware on December 16, 2020 through a corporate conversion (the “Corporate Conversion”) just prior to the Company’s initial public offering (“IPO”). The Company was originally formed on February 28, 2012 as a limited liability company (“LLC”) under the laws of the State of Alabama as Innovative Med Concepts, LLC. On July 23, 2020, the Company changed its name from Innovative Med Concepts, LLC to Virios Therapeutics, LLC. On October 7, 2024, the Company acquired Pharmagesic (Holdings) Inc., a Canadian corporation (“Pharmagesic”) and the parent company of Wex Pharmaceuticals, Inc. (“Wex”), and changed its name from Virios Therapeutics, Inc. to Dogwood Therapeutics, Inc. (the “Name Change”) on October 9, 2024. Prior to the business combination, Pharmagesic was a wholly-owned subsidiary of Sealbond Limited and an indirect wholly-owned subsidiary of CK Life Sciences Int’l., (Holdings) Inc. (“CKLS”), a listed entity on the Main Board of the Hong Kong Stock Exchange.

The Company operates inone segment and is a pre-revenue, development-stage biopharmaceutical company focused on developing new medicines to treat pain and peripheral neuropathy associated with cancer. The Company’s drug candidates include Halneuron®and SP16. Halneuron® is a voltage gated sodium channel inhibitor (Nav 1.7 modulation) presently in Phase 2b development to treat the chronic pain resulting from cancer chemotherapy (“CINP”), with potential to expand into non-neuropathic cancer pain and acute post-surgical pain. Halneuron® has demonstrated effectiveness in reducing both cancer related pain, as well as CINP in prior phase 2 clinical. The Halneuron® Phase 2b CINP study (“HAL-CINP-203”) commenced in the first quarter of 2025. Interim data from HAL-CINP-203 was released in December 2025 and top-line results are expected during the third quarter of 2026. SP16 is a proprietary peptide drug that exhibits immunomodulatory and anti-inflammatory properties and is expected to enter Phase 1 development to treat peripheral neuropathy resulting from cancer chemotherapy (“CIPN”). The neurotrophic effects of SP16 as demonstrated in preclinical research shows potential neuroprotective effects by activating neurite survival and growth in the presence of paclitaxel, highlighting potential to preserve a patient’s full chemotherapy regimen.

Additionally, our pipeline includes IMC-1, a novel, proprietary, fixed dose combination of a nucleoside analog and the anti-inflammatory agent celecoxib for the treatment of fibromyalgia.

Going Concern

Since its founding, the Company has been engaged in research and development activities, as well as organizational activities, including raising capital. The Company has not generated any revenues to date. As such, the Company is subject to all of the risks associated with any development-stage biotechnology company that has substantial expenditures for research and development. Since inception, the Company has incurred losses and negative cash flows from operating activities. The Company has funded its losses primarily through issuance of members’ interests, convertible debt instruments and issuances of equity securities. For the years ended December 31, 2025 and 2024, the Company incurred consolidated net losses of $34,257,370 and $12,349,724, respectively, and had consolidated net cash outflows used in operating activities for the years ended December 31, 2025 and 2024 of $15,618,651 and $8,790,805, respectively. As of December 31, 2025, the Company had a consolidated accumulated deficit of $108,076,316 and is expected to incur losses in the future as it continues its development activities.

Subsequent to year end, on January 11, 2026, the Company entered into an agreement with Maxim Group LLC as placement agent in connection with the issuance and sale by the Company in a registered direct offering of 2,338,948 shares of its Common Stock (the “Registered Offering”), pursuant to an effective shelf registration statement on Form S-3 (File No. 333-287575). In a concurrent private placement (together with the Registered Offering, the “January 2026 Offering”), the Company agreed to sell (i) unregistered pre-funded warrants to purchase up to 2,047,089 shares of Common Stock (the “Pre-funded Warrants”) and (ii) unregistered common

stock warrants to purchase up to 4,386,037 shares of Common Stock (the “Common Stock Warrants”) at a combined offering price of $2.85 per share of Common Stock and accompanying Common Stock Warrant and $2.8499 per Pre-funded Warrant and accompanying Common Stock Warrant. The January 2026 Offering closed on January 13, 2026, and the gross proceeds to the Company were approximately $12.5 million. The net proceeds of the January 2026 Offering were approximately $11.4 million after deducting placement agent fees and offering expenses payable by the Company.

Management anticipates the cash and cash equivalents on hand at December 31, 2025 of approximately $6.5 million plus the additional net proceeds of approximately $11.4 million received from the January 2026 Offering, will fund operations through the third quarter of 2026. The Company will need to secure additional financing to fund its ongoing clinical trials and operations beyond the third quarter of 2026 to continue to execute its strategy. Management plans to explore various dilutive and non-dilutive sources of funding, including equity financings, debt financings, collaboration and licensing arrangements or other financing alternatives. There can be no assurance that management will be successful in raising additional funds or on terms acceptable to the Company. Accordingly, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the issuance date of these consolidated financial statements. The consolidated financial statements have been prepared on a going concern basis and do not include any adjustments to reflect this uncertainty.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Pharmagesic, including Pharmagesic’s wholly owned subsidiary, Wex, and Wex’s wholly owned subsidiaries, IWT Bio, Inc. (“IWT”), Wex Medical Corporation (“WMC”), and Wex Medical Limited (“WML”). All intercompany accounts and transactions have been eliminated in consolidation. The Company has determined the functional currency of Pharmagesic, Wex, IWT and WMC and WML to be the Canadian dollar. The Company translates assets and liabilities of Pharmagesic, Wex, IWT, WMC and WML at exchange rates in effect at the balance sheet date with the resulting translation adjustments directly recorded as a separate component of accumulated other comprehensive income. Income and expense accounts are translated at average exchange rates for the period. Transactions which are not in the functional currency are remeasured into the functional currency and gains and losses resulting from the remeasurement are recorded in foreign currency exchange and other gain (loss), net.

Reverse Stock Split

On October 9, 2024, we effected a reverse stock split of 25 shares for 1 share of Common Stock (the “Reverse Stock Split”). The Reverse Stock Split reduced the number of shares of Common Stock issued (which includes outstanding shares and treasury shares) from 27,950,888 shares to 1,118,035 shares, and reduced shares outstanding from 27,757,937 shares to 1,110,317 shares. There was no change to the total number of shares of Common Stock that the Company is authorized to issue and there was no change in the par value of the Common Stock, and no fractional shares were issued. All share and per share amounts in the financial statements and footnotes have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split. As a result of the Reverse Stock Split, the exercise prices and number of shares to be issued under each of our outstanding option and warrant agreements were proportionately adjusted. The cash settlement of fractional shares that occurred in October 2024 was less than $1,000.

Use of Estimates

The preparation of these consolidated financial statements and accompanying notes in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. In addition, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows. The Company's significant estimates and assumptions include estimated work performed but not yet billed by contract manufacturers and clinical research organizations, the valuation of equity and stock-based related instruments, the valuation allowance related to deferred taxes, the estimated fair value of the net assets acquired in connection with the business combination of Pharmagesic, including impairment of In-Process Research and Development and discount for lack of marketability, the estimated fair value of the contingent value rights (“CVRs”) given to common stockholders at the time of the business combination and recurring reporting period assessments, impairment considerations of intangible assets, the fair value of the preferred stock modification, and the fair value of the consideration provided in connection with the license agreement with Serpin Pharma. Some of these judgments can be subjective and complex, and, consequently, actual results could differ from those estimates. Although the Company believes that its estimates and assumptions are reasonable, they are based upon information available at the time the estimates and assumptions were made. Actual results could differ from those estimates.

Segment Information

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources in assessing performance. The Company hasone reportable segment. The segment consists of the development of clinical and preclinical product candidates focused on advancing novel therapeutics for pain and fatigue illness. The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer.

The accounting policies of the segment are the same as those described in the summary of significant accounting policies. The CODM assesses performance for the segment based on net loss, which is reported on the income statement as consolidated net loss. The measure of segment assets is reported on the balance sheet as total consolidated assets.

To date, the Company has not generated any product revenue. The Company expects to continue to incur significant expenses and operating losses for the foreseeable future as it advances product candidates through all stages of development and clinical trials and, ultimately, seek regulatory approval. As such, the CODM uses cash forecast models in deciding how to invest into the segment. Such cash forecast models are reviewed to assess the entity-wide operating results and performance. Net loss is used to monitor budget versus actual results. Monitoring budgeted versus actual results is used in assessing performance of the segment and in establishing management’s compensation, along with cash forecast models.

The table below summarizes the significant expense categories regularly reviewed by the CODM for the years ended December 31, 2025 and 2024:

Concentrations of Credit Risk

Cash and cash equivalents are potentially subject to concentrations of credit risk. The Company believes it is not exposed to significant credit risk due to the financial strength of the depository institutions in which the cash and cash equivalents are held.

Fair Value Measurements

ASC Topic 820,Fair Value Measurement, provides guidance on the development and disclosure of fair value measurements. Under this accounting guidance, fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.

The accounting guidance classifies fair value measurements in one of the following three categories for disclosure purposes:

The carrying amount of the Company’s consolidated financial instruments, including cash and cash equivalents, accounts payable and accrued expenses approximate their fair values. The Company determined that the fair value of the CVRs were immaterial on the date of issuance as well as at December 31, 2025 and

December 31, 2024, as there were no imminent transactions to indicate value. The fair values of the Company’s debt at December 31, 2024 were estimated using market rates the Company believes would be available for similar types of financial instruments and represent level 2 measurements. See Note 9 below.

Business Combinations

The Company evaluates acquisitions of assets and other similar transactions to assess whether or not the transaction should be accounted for as a business combination or asset acquisition by first applying a screen to determine if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the screen is met, the transaction is accounted for as an asset acquisition. If the screen is not met, further determination is required as to whether or not the Company has acquired inputs and processes that have the ability to create outputs, which would meet the requirements of a business. If determined to be a business combination, the Company accounts for the transaction under the acquisition method of accounting as indicated in ASU 2017-01,Business Combinations (ASC 805), which requires the acquiring entity in a business combination to recognize the fair value of all assets acquired, liabilities assumed, and any non-controlling interest in the acquiree and establishes the acquisition date as the fair value measurement point. Accordingly, the Company recognizes assets acquired and liabilities assumed in business combinations based on the fair value estimates as of the date of acquisition. In accordance with ASC 805,Business Combinations, the Company recognizes and measures goodwill as of the acquisition date, as the excess of the fair value of the consideration paid over the fair value of the identified net assets acquired. If determined to be an asset acquisition, the Company accounts for the transaction in accordance with ASC 805,Business Combinations, and ASC Subtopic 730-10,Research and Development. If the assets acquired are in-process research and development assets that are to be used in a particular research and development project and have no alternative future use, under ASC Subtopic, 730-10,Research and Development, these costs along with direct transaction costs are expensed immediately.

Cash and Cash Equivalents

Cash and cash equivalents are maintained in bank deposit accounts and money market funds that are readily convertible into cash, which exceed the federally insured limits of $250,000.

Property and Equipment

Property and equipment are carried at acquisition cost less accumulated depreciation, subject to review for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable as described further under the heading "Impairment of Long-Lived Assets" below.

Depreciation and amortization are computed using the straight-line method based on the estimated useful lives of the related assets. Leasehold improvements are amortized over the term of the lease. Office equipment and furniture are depreciated over five years and computer software and equipment are depreciated overtwo years.

When an asset is disposed of, the associated cost and accumulated depreciation is removed from the related accounts on the Company’s consolidated balance sheet with any resulting gain or loss included in the Company's consolidated statement of operations.

Indefinite-Lived Intangible Assets

Indefinite-lived intangible assets consist of IPR&D. The fair values of IPR&D project assets acquired in business combinations are capitalized. The Company generally utilizes the Multi-Period Excess Earning Method to determine the estimated fair value of the IPR&D assets acquired in a business combination and for subsequent annual impairment testing. The projections used in this valuation approach are based on many factors, such as relevant market size, the estimated probability of regulatory success rates, anticipated patent protection, expected pricing, expected treated population, and estimated payments. The estimated future net

cash flows are then discounted to the present value using an appropriate discount rate. These assets are treated as indefinite-lived intangible assets until completion or abandonment of the projects, at which time the assets are amortized over the remaining useful life or written off, as appropriate.

Intangible assets with indefinite lives, including IPR&D, are tested for impairment if impairment indicators arise and, at a minimum, annually. However, an entity is permitted to first assess qualitative factors to determine if a quantitative impairment test is necessary. Further testing is only required if the entity determines, based on the qualitative assessment, that it is more likely than not that an indefinite-lived intangible asset’s fair value is less than its carrying amount. Otherwise, no further impairment testing is required. The indefinite-lived intangible asset impairment test consists of a one-step analysis that compares the fair value of the intangible asset with its carrying amount. If the carrying amount of an intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. The Company considers many factors in evaluating whether the value of our intangible assets with indefinite lives may not be recoverable, including, but not limited to, recent clinical data, expected growth rates, the cost of equity and debt capital, general economic conditions, outlook and market performance of the Company’s industry and recent and forecasted financial performance.

The Company evaluates indefinite-lived intangible assets for impairment at least annually on October 1 and whenever facts and circumstances indicate that their carrying amounts may not be recoverable. For the years ended December 31, 2025 and 2024, the Company determined that there wasno impairment to IPR&D.

Goodwill

Goodwill represents the amount of consideration paid in excess of the fair value of net assets acquired as a result of the Company’s business acquisitions accounted for using the acquisition method of accounting. The intangible assets acquired represented the fair value of IPR&D which has been recorded on the accompanying consolidated balance sheet as indefinite-lived intangible assets. A deferred tax liability was recorded for the difference between the fair value of the acquired IPR&D and its tax basis which was recognized as goodwill in applying the purchase method of accounting. Goodwill is not amortized and is subject to impairment testing at a reporting unit level on an annual basis or when a triggering event occurs that may indicate the carrying value of the goodwill is impaired. An entity is permitted to first assess qualitative factors to determine if a quantitative impairment test is necessary. Further testing is only required if the entity determines, based on the qualitative assessment, that it is more likely than not that the fair value of the reporting units is less than its carrying amount.

The Company evaluates goodwill for impairment at least annually on October 1 and whenever facts and circumstances indicate that its carrying amount may not be recoverable. When conducting our annual impairment test, we elected to perform a quantitative assessment. As the Company consists ofone reporting unit, the Company compares the estimated fair value of our reporting unit to its carrying value. If the fair value exceeds the carrying value, no further evaluation is required, and no impairment exists. If the carrying amount exceeds the fair value, the difference between the carrying value and the fair value is recorded as an impairment loss, the amount of which may not exceed the total amount of goodwill. The Company determined the fair value of the reporting unit based upon the quoted market price and related market capitalization of the Company’s common stock, adjusted for an estimated control premium. For the years ended December 31, 2025 and 2024, the Company determined that there wasno impairment to goodwill.

Operating Lease Right-of-use Asset and Lease Liability

The Company accounts for leases under ASC 842,Leases. Operating leases are included in “Right-of-use assets” within the Company’s consolidated balance sheets and represent the Company’s right to use an underlying asset for the lease term. The Company’s related obligation to make lease payments are included in “Lease liability” and “Lease liability, net of current portion” within the Company’s consolidated balance sheets. Operating lease right-of-use (“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 lease does not provide an implicit rate, the Company uses its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis

over a similar term, an amount equal to the lease payments in a similar economic environment. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The ROU assets are tested for impairment according to ASC 360,Property, Plant, and Equipment (“ASC 360”). Leases with an initial term of 12 months or less are not recorded on the balance sheet and are recognized as lease expense on a straight-line basis over the lease term.

As of December 31, 2025 and 2024, the Company’s operating lease ROU assets and corresponding short-term and long-term lease liabilities primarily relate to the operating lease for an office in Vancouver, British Columbia, that was acquired as part of the Business Combination with Pharmagesic. The office lease expires on August 31, 2028.

Impairment of Long-Lived Assets

In accordance with ASC 360-10-35,Impairment or Disposal of Long-Lived Assets, the Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable (i.e., impaired). Once an impairment is determined, the actual impairment recognized is the difference between the carrying amount and the fair value (less costs to sell for assets to be disposed of) as estimated using one of the following approaches: income, cost, and/or market. Fair value using the income approach is determined primarily using a discounted cash flow model that uses the estimated cash flows associated with the asset or asset group under review, discounted at a rate commensurate with the risk involved. Fair value utilizing the cost approach is determined based on the replacement cost of the asset reduced for, among other things, depreciation and obsolescence. Fair value, utilizing the market approach, benchmarks the fair value against the carrying amount.

Redeemable and Convertible Preferred Stock

The Company applies ASC 480,Distinguishing Liabilities from Equity, when determining the classification and measurement of its preferred stock. Preferred shares subject to mandatory redemption are classified as liability instruments and are measured at fair value. Conditionally redeemable preferred shares (including preferred shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, preferred shares are classified as stockholders’ equity (deficit). See Note 10 to these consolidated financial statements.

Income Taxes

The Company provides for income taxes using the asset and liability approach. Deferred tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities and the tax rates in effect when these differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company operated as an Alabama limited liability company until its Corporate Conversion. Therefore, the Company passed through all income and losses to its members until this point.

The Company is subject to the provisions of ASC 740,Income Taxes (“ASC 740”). Under ASC 740, consideration is given to the recognition and measurement of tax positions that meet a “more-likely-than-not” threshold. A tax position is a position taken in a previously filed tax return or a position expected to be taken in a future that is reflected in measuring current or deferred income tax assets and liabilities. Tax positions include the Company’s status as a pass-through entity until December 16, 2020 and as a corporation thereafter. The recognition and measurement of tax positions taken for various jurisdictions consider the amounts and probabilities of outcomes that could be realized upon settlement using the facts, circumstances, and information available at the reporting date. The Company has determined that it has tax expense of $221,096 and a tax benefit of $503 as of December 31, 2025 and 2024, respectively, and does not have any material unrecognized tax benefits or obligations as of December 31, 2025 and 2024. The Company recognizes interest and penalties

related to uncertain tax positions, if any, in income tax expense. The Company is not currently under examination by the Internal Revenue Service or by state tax authorities and the Company’s tax year remains subject to examination by the tax authorities.

Net Income (Loss) per Common Share Applicable to Common Stockholders

The Company uses the two-class method to compute net income per common share during periods the Company realizes net income and has securities outstanding that entitle the holder to participate in dividends and earnings of the Company. In addition, the Company analyzes the potential dilutive effect of outstanding participating securities under the "if-converted" method when calculating diluted earnings per share and reports the more dilutive of the approaches (two class or "if-converted"). The two-class method is not applicable during periods with a net loss, as the holders of participating securities have no obligation to fund losses.

Basic and Diluted Net Income (Loss) per Share

Basic net loss per common share (“EPS”) is computed in accordance with U.S. GAAP. Basic EPS is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted EPS reflects potential dilution and is computed by dividing net loss by the weighted average number of common shares outstanding during the period increased by the number of additional common shares that would have been outstanding if all potential common shares had been issued and were dilutive. However, potentially dilutive securities are excluded from the computation of diluted EPS to the extent that their effect is anti-dilutive. For the years ended December 31, 2025 and 2024, the Company had options to purchase 1,117,278 and 92,777 shares of Common Stock, respectively, warrants to purchase 855 and 7,755 shares of Common Stock, respectively, and preferred stock which was convertible into 0 and 22,138,044 shares of Common Stock, respectively, that were anti-dilutive.

Research and Development

Research and development costs are expensed as incurred. The Company arranges and contracts with third-party contract research organizations (“CROs”), contract development and manufacturing organizations (“CMOs”), contractor laboratories and independent consultants. As part of the process of preparing its financial statements, the Company may be required to estimate some of its expenses resulting from its obligations under these arrangements and contracts. 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. The Company’s objective is to reflect the appropriate expenses in its financial statements by matching those expenses with the period in which services are rendered. The Company determines any accrual estimates based on account discussions with applicable personnel and outside service providers as to the progress or state of completion. The Company makes estimates of its accrued expenses as of each balance sheet date based on the facts and circumstances known at that time. The Company’s estimates are dependent upon the timely and accurate reporting of CROs, CMOs and other third-party vendors. At the end of each reporting period, the Company compares the payments made to each service provider to the estimated progress towards completion of the related project. Factors that the Company considers in preparing these estimates include the number of patients enrolled in studies, milestones achieved, and other criteria related to the efforts of its vendors. These estimates will be subject to change as additional information becomes available. Depending on the timing of payments to vendors and estimated services provided, the Company will record prepaid or accrued expenses related to these costs.

Share-Based Compensation

The Company recognizes compensation expense relating to share-based awards to employees and directors with a performance condition over the requisite service period if it is probable that the performance condition will be satisfied. For awards to non-employees, the Company recognizes compensation expense in the same manner as if the Company had paid cash for the goods or services. The Company estimates the fair value of options and warrants granted using an options pricing model, see Note 13. Expense is recognized

within both research and development and general and administrative expenses and forfeitures are recognized as they are incurred.

Recently Adopted Accounting Standards

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09,Improvements to Income Tax Disclosures (Topic 740), which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. The new guidance requires consistent categorization and greater disaggregation of information in the rate reconciliation, as well as further disaggregation of income taxes paid. This change is effective for annual periods beginning after December 15, 2024. The guidance is to be applied on either a prospective or a retrospective basis to annual financial statements for periods beginning after the effective date. The Company adopted ASU 2023-09 on a prospective basis for the fiscal year ended December 31, 2025. See added disclosures in Note 14.

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2023-07, “Segment Reporting (ASC 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The guidance is to be applied retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. The Company adopted ASU 2023-07 for the fiscal year ended December 31, 2024. See Segment Information above.

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, which improves disclosures about an entity’s expenses and addresses requests from investors for more detailed information about types of expenses including purchases of inventory, employee compensation, depreciation, amortization, and depletion, commonly presented in cost of sales, research and development and general and administrative expenses. In January 2025, the FASB issued ASU 2025-01 which revises the effective date of ASU 2024-03. Adoption of these new disclosure requirements are effective for public entities for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027 and early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.

In May 2025, the FASB issued ASU 2025-03,Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity, to improve the requirements for identifying the accounting acquirer in Topic 805,Business Combinations. The amendments in ASU 2025-03 revise current guidance for determining the accounting acquirer for a transaction effected primarily by exchanging equity interests in which the legal acquiree is a variable interest entity (“VIE”) that meets the definition of a business. The amendments require that an entity consider the same factors that are currently required for determining which entity is the accounting acquirer in other acquisition transactions. Entities will be required to apply the new guidance prospectively to any acquisition transaction that occurs after the initial application date. Adoption of this guidance is effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods and early adoption is permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.

Subsequent Events

On January 9, 2026, the Company provided notice of its termination, effective January 9, 2026, of the Northland Agreement. The Company is not subject to any termination penalties related to the termination of the Northland Agreement.

Subsequent to year end, on January 11, 2026, the Company entered into an agreement with Maxim Group LLC as placement agent in connection with the issuance and sale by the Company in a registered direct offering of 2,338,948 shares of its Common Stock (the “Registered Offering”), pursuant to an effective shelf registration statement on Form S-3 (File No. 333-287575). In a concurrent private placement (together with the Registered Offering, the “January 2026 Offering”), the Company agreed to sell (i) unregistered pre-funded warrants to purchase up to 2,047,089 shares of Common Stock (the “Pre-funded Warrants”) and (ii) unregistered common stock warrants to purchase up to 4,386,037 shares of Common Stock (the “Common Stock Warrants”) at a combined offering price of $2.85 per share of Common Stock and accompanying Common Stock Warrant and $2.8499 per Pre-funded Warrant and accompanying Common Stock Warrant. The January 2026 Offering closed on January 13, 2026, and the gross proceeds to the Company were approximately $12.5 million. The net proceeds of the January 2026 Offering were approximately $11.4 million after deducting placement agent fees and offering expenses payable by the Company.

On January 15, 2026 the Company filed a Form S-3 Registration Statement for the resale of up to 6,433,126 shares of the Company’s Common Stock consisting of (i)2,047,089 shares of Common Stock underlying the Pre-Funded Warrants at an exercise price of $0.0001 per share; and (ii)4,386,037 shares of Common Stock underlying the Common Stock Warrants to purchase shares of Common Stock at an exercise price of $3.28 per share. The Form S-3 Registration Statement was declared effective on January 29, 2026.

Subsequent to year end, the Company received notification and payment for the exercise of 1,319,089 Pre-Funded Warrants at an exercise price of $0.0001 per share and 1,319,089 shares of Common Stock were issued. As of March 10, 2026, there are 728,000 Pre-Funded Warrants outstanding.

3. Business Combination

On October 7, 2024, the Company entered into a Share Exchange Agreement (the “Exchange Agreement”) with Sealbond Limited, a British Virgin Islands corporation (“Sealbond”), pursuant to which the Company acquired 100% of the issued and outstanding common shares of Pharmagesic (Holdings) Inc., a Canadian corporation (“Pharmagesic”) (such transaction, the “Combination”). Prior to the Combination, Pharmagesic was a wholly-owned subsidiary of Sealbond and an indirect wholly-owned subsidiary of CK Life Sciences Int’l., (Holdings) Inc. (“CKLS”), a listed entity on the Main Board of the Hong Kong Stock Exchange.

Under the terms of the Exchange Agreement, on October 7, 2024 (the “Closing”), in exchange for all of the outstanding common shares of Pharmagesic immediately prior to the Effective Time, the Company issued to Sealbond, as sole shareholder of Pharmagesic, an aggregate of (A)211,383 shares of the Company’s unregistered Common Stock, which shares shall represent a number of shares equal to no more than 19.99% of the outstanding shares of Common Stock as of immediately before the Effective Time and (B)2,108.3854 shares of the Company’s unregistered Series A Non-Voting Convertible Preferred Stock, par value $0.0001 per share (“Series A Preferred Stock”) (as described below). The issuance of the shares of Common Stock and Series A Preferred Stock to Sealbond occurred on October 9, 2024. Each share of Series A Preferred Stock is convertible into 10,000 shares of Common Stock, subject to certain conditions described in the Exchange Agreement.

The Board of Directors of the Company (the “Board”) approved the Exchange Agreement and the related transactions, and the consummation of the Combination was not subject to approval of Company stockholders. Pursuant to the Exchange Agreement, the Company agreed to hold a stockholders’ meeting to submit the certain matters to its stockholders for their consideration, including: (i) the approval of the conversion of shares of Series A Preferred Stock into shares of Common Stock in accordance with the rules of the Nasdaq Stock Market LLC (the “Conversion Proposal”) and (ii) the approval of a “change of control” under Nasdaq Listing Rules 5110 and 5635(b) (the “Change of Control Proposal”); and together with the Conversion Proposal, the “Meeting Proposals”). At a special meeting of stockholders on November 21, 2025, the Meeting Proposals were approved.

The Company’s transaction costs of$4.9 million were expensed as incurred and included in the General and Administration expenses in the Company’s consolidated statement of operations.

The transaction was accounted for under the acquisition method of accounting. Under the acquisition method, the total purchase price of the acquisition is allocated to the net tangible and identifiable intangible assets acquired and liabilities assumed based on the fair values as of the date of the acquisition. Consideration paid is comprised of the estimated fair value of various securities issued including the Series A Preferred Stock and Common Stock issued to Sealbond, the sole shareholder of Pharmagesic. In the fourth quarter of fiscal 2024, the preliminary purchase price allocation was updated, including the related determination of fair value of these securities issued as consideration, the allocation of consideration to the specific in-process research and development programs acquired and the related tax implications for the updates to the purchase price allocation.

The fair value of the consideration totaled approximately$71.3 million, summarized as follows:

The Company recorded the assets acquired and liabilities assumed as of the date of the Combination based on the information available at that date. The following table presents the allocation of the purchase price to the estimated fair values of the assets acquired and liabilities assumed as of the Combination date:

The fair value of IPR&D was capitalized as of the Combination date and accounted for as indefinite-lived intangible assets until completion or disposition of the assets or abandonment of the associated research and development efforts. Upon successful completion of the development efforts, the useful lives of the IPR&D

assets will be determined based on the anticipated period of regulatory exclusivity and will be amortized within operating expenses. Until that time, the IPR&D assets will be subject to impairment testing and will not be amortized. The goodwill recorded related to the acquisition is the excess of the fair value of the consideration transferred by the acquirer over the fair value of the net identifiable assets acquired and liabilities assumed at the date of the Combination. The goodwill recorded is not deductible for tax purposes.

The following summarizes the Company’s intangible assets and goodwill acquired in connection with the Combination and their carrying value as of December 31, 2025 and 2024.

Intangible asset fair values for the two IPR&D programs were determined using the Multi-Period Excess Earnings Method (“MPEEM”) which is a form of the income approach. Under the MPEEM, the fair value of an intangible asset is equal to the present value of the asset's incremental after-tax cash flows (excess earnings) remaining after deducting the market rates of return on the estimated value of contributory assets (contributory charge) over its remaining useful life. To calculate fair value of acquired IPR&D programs under the MPEEM, the Company uses probability-weighted cash flows discounted at a rate considered appropriate given the significant inherent risks associated with drug development by development-stage companies. Cash flows were calculated based on estimated projections of revenues and expenses related to each program and then reduced by a contributory charge on requisite assets employed. Contributory assets included debt-free working capital, net fixed assets and assembled workforce. Rates of return on the contributory assets were based on rates used for comparable market participants. Cash flows were assumed to extend through the market exclusivity period estimated to be provided by trade-secrets and patents for the synthetic manufacture of drug product. The resultant cash flows were then discounted to present value using a weighted-average cost of equity capital for companies with profiles substantially similar to that of each acquired IPR&D program, which the Company believes represents the rate that market participants would use to value the assets. The Company compensated for the phase of development of each program by probability-adjusting its estimation of the expected future cash flows. The projected cash flows were based on significant assumptions, such as the time and resources needed to complete the development and approval of each IPR&D program, estimates of revenue and operating profit related to the program considering its stage of development, the life of the potential commercialized product and associated risks, including the inherent difficulties and uncertainties in drug development, such as obtaining marketing approval from the FDA and other regulatory agencies, and risks related to the viability of and potential alternative treatments in any future target markets.

In consideration of the Licensing Agreement, the Company issued shares of common

stock and Series A-2 Non-Voting Convertible Preferred Stock to Serpin Pharma and Rejuvenation.

9. Promissory Note with Related Party

On October 7, 2024, in connection with the Exchange Agreement, the Company entered into a Loan Agreement (the “Loan Agreement”) with Conjoint Inc., a Delaware corporation (“Lender”) and an affiliate of CKLS. Pursuant to the Loan Agreement, Lender agreed to make a loan to the Company in the aggregate principal amount of $19,500,000, of which (i) $16,500,000 was disbursed on October 7, 2024 and (ii) $3,000,000 was disbursed on February 18, 2025. Pursuant to the terms of the Loan Agreement, the proceeds were to be used for the purpose of (1) funding operations and (2) performing clinical and research & development activities related to Halneuron®. The Loan Agreement bore interest at the Secured Overnight Financing Rate (“SOFR”) plus 2.00%, that increases by 1.00% in the event of default that resets on an annual basis on October 1st. The Loan Agreement was payable in full with principal and accrued interest on October 7, 2027. The promissory note was recorded net of issuance costs of $1,177,355. The issuance costs were being amortized to interest expense using an effective interest rate of 7.82%. For the year ended December 31, 2025, the Company recognized interest expense of $197,437 and amortization of issuance costs of $52,373 in the accompanying consolidated statement of operations and comprehensive loss. As of the year ended December 31, 2024, the Company recognized interest expense of $229,454 and amortization of issuance costs of $58,432 in the accompanying consolidated statements of operations.

On March 12, 2025, the Company entered into the Exchange and Cancellation Agreement with the Lender.

of $7.01. The price was determined by reference to the average Nasdaq Official Closing Price of the Company’s common stock for thefive trading days immediately prior to the signing of the Exchange and Cancellation Agreement. Each share of Series A-1 Preferred Stock was convertible into 10,000 shares of common stock, subject to certain conditions set forth in the Series A-1 Preferred Stock Certificate of Designation (“Series A-1 Certificate of Designation”), as discussed below.

The Company evaluated the transaction in accordance with ASC 470-50-40,Debt Modifications and Extinguishment. As such, the Company recognized a loss on the debt extinguishment of $6,134,120 that was charged to other expense in the accompanying consolidated statements of operations and comprehensive income for the year ended December 31, 2025. The loss was determined by the difference between the closing price of the Company’s common stock of $11.13 on the transaction date to the price per share used to determine the conversion price of the debt, discounted for lack of marketability.

As of December 31, 2024, the Company evaluated the fair value of its related party note payable by analyzing the terms of the instrument in comparison to a synthetic credit rating and implied market cost of debt rate.

10. Stockholders’ Equity (Deficit)

Preferred Stock

The restated certificate of incorporation, as amended, of the Company permits its Board of Directors to issue up to 2,000,000 shares of preferred stock, par value of $0.0001 per share, in one or more series, to designate the number of shares constituting such series, and fix by resolution, the powers, privileges, preferences and relative, option or special rights thereof, including liquidation preferences and dividends, and conversion and redemption rights of each such series.

After giving effect to the designation of Series A Preferred Stock, Series A-1 Preferred Stock and Series A-2 Preferred Stock discussed below, the Company had 1,997,254 and 1,997,730 authorized and remaining to be issued shares of preferred stock at December 31, 2025 and 2024, respectively.

Series A Preferred Stock

In October 2024, the Board of Directors designated 2,270 of the 2,000,000 shares of preferred stock to be Series A Non-Voting Convertible Preferred Stock (“Series A Preferred Stock”). As of December 31, 2025, the Company had 2,270 authorized and 2,269.1494 issued andno shares outstanding of Series A Preferred Stock and as of December 31, 2024, the Company had 2,270 authorized and 2,213.8044 issued and outstanding shares of Series A Preferred Stock.

Following stockholder approval of the Conversion Proposal at a special meeting of stockholders held on November 21, 2025, each share of Series A Preferred Stock automatically converted into 10,000 shares of Common Stock. In accordance with ASC 805-50-25-4, the Company has the option to apply pushdown accounting to its financial statements related to the conversion of the Series A Preferred Stock but does not believe that such an election would be meaningful or informative to readers of the financial statements. The original issuance of the Series A Preferred Stock has been disclosed since the transaction was completed, including disclosures related to its expected conversion to shares of Common Stock at a future special meeting of stockholders, and the conversion followed the original terms of the Exchange Agreement. Accordingly, the conversion was treated as an exchange of securities by an investor with the conversion completed at the carrying amount of the Series A Preferred Stock.

Except as otherwise required by law, the Series A Preferred Stock did not have voting rights. However, as long as any shares of Series A Preferred Stock were outstanding, the Company could not, without the affirmative vote of the holders of a majority of the then-outstanding shares of the Series A Preferred Stock, (i) alter or change adversely the powers, preferences or rights given to the Series A Preferred Stock or alter or amend the Certificate of Designation, amend or repeal any provision of, or add any provision to, the Charter or Amended and Restated Bylaws of the Company, or file any articles of amendment, certificate of designations, preferences, limitations and relative rights of any series of Preferred Stock, if such action would adversely alter or change the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series A Preferred Stock, regardless of whether any of the foregoing actions shall be by means of amendment to the Charter or by merger, consolidation, recapitalization, reclassification, conversion or otherwise, (ii) issue further shares of Series A Preferred Stock, or increase or decrease (other than by conversion) the number of authorized shares of Series A Preferred Stock (iii) prior to the Stockholder Approval (as defined in the Certificate of Designation) or at any time while at least 30% of the originally issued Series A Preferred Stock remains issued and outstanding, consummate either: (A) any Fundamental Transaction (as defined in the Certificate of Designation) or (B) any merger or consolidation of the Company with or into another entity or any stock sale to, or other business combination in which the stockholders of the Company immediately before such transaction do not hold at least a majority of the capital stock of the Company immediately after such transaction, or (iv) enter into any agreement with respect to any of the foregoing.

The Series A Preferred Stock ranked on parity with the Common Stock as to distributions of assets upon liquidation, dissolution or winding-up of the Company, whether voluntarily or involuntarily. The Series A Preferred Stock were entitled to receive on an as-converted basis dividends equal to and in the same form, and in the same manner, as dividends paid to shares of Common Stock. If, prior to conversion of the Series A Preferred Stock into Common Stock, the Company effected any Fundamental Transaction (as defined in the Series A Certificate of Designation) then upon conversion of the Series A Preferred Stock, the holders of the Series A Preferred Stock would have been entitled to receive, in lieu of shares of Common Stock, the consideration that would have been issuable upon such Common Stock had the conversion occurred prior to such Fundamental Transaction.

In accordance with ASC 480-10-S99-3A, the Company had classified the Series A Preferred Stock outside of permanent equity, in the mezzanine section of the consolidated balance sheet. In addition, this guidance requires that redeemable equity securities be accreted to their redemption value if it becomes probable that the security will become redeemable. The guidance further clarifies that accretion is required when redemption is likely to occur, and that the assessment of probability should be updated at each reporting period. The term “probable” is defined in ASC 450,Contingencies, subparagraph 450-20-20 as “the future event or events are likely to occur.” With this framework in mind, the Company has evaluated each conditional repurchase (as described below under “Form of Repurchase Agreement and Modification”) and redemption right embedded in the Series A Preferred Stock to determine whether exercise of any right is probable for purposes of accretion to redemption value. Based on the facts and circumstances, none of the conditional repurchase or redemption rights were considered probable prior to the conversion of the Series A Preferred Stock and there has been no accretion to redemption value included in the consolidated financial statements.

Per the Series A Certificate of Designation, holders of Series A Preferred Stock were entitled to receive a PIK dividend accruing at a rate equal to five percent (5.0%) per annum payable in shares of Series A Preferred Stock on the date that was 180 days after the original issue date of the Series A Preferred Stock. As of March 31, 2025, the Company had accrued the full value of the dividend payable of $1,770,767. On April 7, 2025,180 days after the original issue date, the Company issued an aggregate of 55.345 shares of Series A Preferred stock as a PIK dividend to the holders of Series A Preferred Stock.

Form of Repurchase Agreement and Modifications

The terms of the Exchange Agreement provides that Sealbond had the right to exercise an option, but not an obligation, after the Closing and upon the occurrence of certain conditional events including continued listing requirements, to acquire all of the Company’s and its direct and indirect subsidiaries’ intellectual property, rights,

title, regulatory submissions, assignment of contracts, data and interests, as of the time of such acquisition, in and to tetrodotoxin and Halneuron®, in accordance with the terms and conditions of the form of Repurchase Agreement for a cash settlement value as defined in the agreement.

In September 2025, holders of certain Series A Preferred Stock irrevocably waived the cash settlement and related repurchase rights for 166 shares of Series A Preferred Stock. As such, the Company reclassified approximately $5.5 million and 166 shares from temporary equity to permanent equity as the shares no longer qualified for temporary equity classification under ASC 480-10-S99-3A. In addition, the Company considered under ASC 470,Debt, whether or not the Series A Preferred Stock underlying the waivers should be treated as a modification or as an extinguishment for financial reporting purposes. The Company used the fair value method and determined that the fair value of the Series A Preferred Stock before the waiver was not significantly different (e.g. less than 10%) than the fair value of the Series A Preferred Stock immediately after the waiver and thus the waiver was considered a modification. Accordingly, there was no impact to net income or earnings per share, and any directly related fees were expensed as incurred.

Contingent Value Rights Agreement

Concurrently with the Closing of the Combination, the Company entered into a contingent value rights agreement (the “CVR Agreement”) with a rights agent (the “Rights Agent”), pursuant to which each holder of Common Stock as of October 17, 2024, including those holders receiving shares of Common Stock in connection with the Combination, was entitled toone contractual contingent value right (each, a “CVR”) issued by the Company, subject to and in accordance with the terms and conditions of the CVR Agreement, for each share of Common Stock held by such holder as of 5:00 p.m. Eastern Daylight Time on October 17, 2024. The CVR Agreement has a term ofseven years.

Each contingent value right entitles the holders (the “Holders”) thereof, in the aggregate, to 87.75% of any Upfront Payment (as defined in the CVR Agreement) or Milestone Payment (as defined in the CVR Agreement) received by the Company in a given calendar quarter.

The distributions in respect of the CVRs that become payable will be made on a quarterly basis and will be subject to a number of deductions, subject to certain exceptions or limitations, including but not limited to for certain taxes and certain out-of-pocket expenses incurred by the Company.

Under the CVR Agreement, the Rights Agent has, and Holders of at least 30% of the CVRs then-outstanding have, certain rights to audit and enforcement on behalf of all Holders of the CVRs. The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than as permitted pursuant to the CVR Agreement. The Holders of the CVRs do not have the rights of a shareholder and do not have the ability to vote, rights to dividends, or other interests. The CVRs also establish certain restrictions of mergers and change in control activities, as defined in the agreement.

The Company determined that the fair value of the CVRs were immaterial on the date of issuance as there were no imminent transactions to indicate value. The Company evaluates the fair value of the CVRs at each reporting period or whenever facts and circumstances indicate that their carrying amounts may have changed. The Company determined that the fair value of the CVRs were immaterial as of December 31, 2025 and 2024.

Series A-1 Preferred Stock

In March 2025, the Board of Directors designated 285 shares of the preferred stock to be Series A-1 Preferred Stock. As of December 31, 2025, the Company had 285 shares authorized,284.2638 shares issued andno shares outstanding of Series A-1 Preferred Stock. There wereno authorized, issued andoutstanding shares of Series A-1 Preferred stock at December 31, 2024.

Following stockholder approval at a special meeting of stockholders held on November 21, 2025, each share of Series A-1 Preferred Stock automatically converted into 10,000 shares of Common Stock. The

conversion was treated as an exchange of securities by an investor with the conversion completed at the carrying amount of the Series A-1 Preferred Stock.

The Series A-1 Preferred Stock ranked on parity with the Common Stock as to distributions of assets upon liquidation, dissolution or winding-up of the Company, whether voluntarily or involuntarily. The Series A-1 Preferred Stock were entitled to receive on an as-converted basis dividends equal to and in the same form, and in the same manner, as dividends paid to shares of Common Stock. If, prior to conversion of the Series A Preferred Stock into Common Stock, the Company effects any Fundamental Transaction (as defined in the Series A-1 Certificate of Designation) then upon conversion of the Series A-1 Preferred Stock, the holders of the Series A-1 Preferred Stock shall be entitled to receive, in lieu of shares of Common Stock, the consideration that would have been issuable upon such Common Stock had the conversion occurred prior to such Fundamental Transaction.

Except as otherwise required by law, the Series A-1 Preferred Stock did not have voting rights. However, as long as any shares of Series A-1 Preferred Stock were outstanding, the Company could not, without the affirmative vote of the holders of a majority of the then-outstanding shares of the Series A-1 Preferred Stock, (i) alter or change adversely the powers, preferences or rights given to the Series A-1 Preferred Stock or alter or amend the Series A-1 Certificate of Designation, amend or repeal any provision of, or add any provision to, the Charter or Amended and Restated Bylaws of the Company, or file any articles of amendment, certificate of designations, preferences, limitations and relative rights of any series of Preferred Stock, if such action would adversely alter or change the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series A-1 Preferred Stock, regardless of whether any of the foregoing actions shall be by means of amendment to the Charter or by merger, consolidation, recapitalization, reclassification, conversion or otherwise, (ii) issue further shares of Series A-1 Preferred Stock, or increase or decrease (other than by conversion) the number of authorized shares of Series A-1 Preferred Stock, (iii) prior to the Stockholder Approval (as defined in the Series A-1 Certificate of Designation) or at any time while at least 30% of the originally issued Series A-1 Preferred Stock remains issued and outstanding, consummate either: (A) any Fundamental Transaction (as defined in the Series A-1 Certificate of Designation) or (B) any merger or consolidation of the Company with or into another entity or any stock sale to, or other business combination in which the stockholders of the Company immediately before such transaction do not hold at least a majority of the capital stock of the Company immediately after such transaction, or (iv) enter into any agreement with respect to any of the foregoing.

Series A-2 Preferred Stock

In September 2025, the Board of Directors designated 190.0572 shares of the preferred stock to be Series A-2 Preferred Stock. As of December 31, 2025, the Company has 190.0572 shares authorized and issued andno shares outstanding of Series A-2 Preferred Stock.

In addition to the stock options issued under the Plan, and in conjunction with the IPO, the Company granted non-qualified stock options to purchase 11,700 shares of common stock as provided for in the employment agreement of our former President, Richard Burch (the “President Options”). The President Options are exercisable within 10 years of the date of grant at $250.00 per share, were 100% vested at the grant date and have a remaining contractual term of 4.96 years. As of December 31, 2025, there wasno unrecognized compensation expense related to these options as they were 100% vested upon issuance. The shares of common stock issuable upon exercise of the President Options will be unregistered, and the option agreement does not include any obligation on the part of the Company to register such shares of common stock.

14. Income Taxes

As of December 31, 2025, the Company has U.S. federal net operating loss carryforwards of approximately $45,410,000, which have an indefinite carryforward and Georgia and Florida state net operating loss carryforwards of approximately $58,689,000 and $1,750,000, respectively, which have atwenty-year carryforward and begin expiring in 2037. As of December 31, 2025, the Company had Canadian non-capital loss carryforwards of approximately $22,024,000, which have atwenty year carryforward and begin expiring in 2026 and Hong Kong tax losses carryforwards of approximately $58,026,000 which have no expiry. These net operating loss carryforwards may be limited under Section 382 of the internal revenue code. The Company will need to perform a formal Section 382 study to determine how the equity transactions discussed above impact the limitation on the utilization of its net operating loss carryforwards.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted. The OBBBA did not change the US federal corporate income-tax rate and did not materially affect Dogwood’s US income-tax position. The OBBBA did reinstate the immediate expensing of domestic research and development (“R&D”) expenditures under Section 174A, effective for tax years beginning after December 31, 2024. This change reverses the prior requirement to capitalize and amortize R&D costs over five years. The Company has elected to continue to capitalize R&D expenditures under Section 174A and amortize these costs over 60-months. Therefore there was no remeasurement of deferred tax assets due to the OBBBA’s enactment and there was no impact on the Company’s income tax provision for the year ended December 31, 2025. The Company maintains a full

valuation allowance against its deferred tax assets, including those related to net operating loss carryforwards and R&D credits.

The Company adopted ASU 2023-09 effective January 1, 2025, applying the guidance prospectively, as permitted by the standard. Comparative prior-year disclosures have not been restated. The adoption of ASU 2023-09 did not affect the Company’s recognition or measurement of income tax amounts, as the ASU amends disclosure requirements only and does not modify the underlying accounting guidance in ASC 740.

Income taxes paid by the Company are as follows:

A reconciliation of the worldwide consolidated income tax rate to the Company’s effective tax rate as of December 31, 2025 is as follows:

A reconciliation of the worldwide consolidated income tax rate to the Company’s effective tax rate as of December 31, 2024 is as follows:

Deferred taxes are recognized for temporary differences between the basis of assets and liabilities for financial statement and income tax purposes. The significant components of the Company’s deferred tax assets are comprised of the following:

For tax years beginning on or after January 1, 2022, the 2017 Tax Cuts and Jobs Act amended Section 174 of the code to eliminate current-year deductibility of research and development expenses and requires taxpayers to capitalize and amortize them over five years for research activities performed in the United States and fifteen years for research activities performed outside of the United States. For the 2025 and 2024 tax years, the Company has capitalized $8,871,522 and $2,810,785 of research and development expenses, respectively.

At December 31, 2024, the Company evaluated the realizability of its deferred tax assets and determined that the valuation allowance should be adjusted for the consideration of the acquired in-process research and development intangible assets. An income tax benefit for the year ended December 31, 2025 is reflected in the consolidated statement of operations.

The Company experienced a net change in valuation allowance of $5,582,085 and $21,443,255 for the years ended December 31, 2025 and 2024, respectively. The large valuation adjustment for the year ended December 31, 2024, primarily related to the Combination of Pharmagesic and acquired in-process research and development intangible assets.

The components of the income tax expense (benefit) are as follows:
