Outlook Therapeutics, Inc.

1. Organization and Operations

Description of the Business

Outlook Therapeutics, Inc. (“Outlook” or the “Company”) was incorporated in New Jersey on January 5, 2010, started operations in July 2011, reincorporated in Delaware by merging with and into a Delaware corporation in October 2015 and changed its name to “Outlook Therapeutics, Inc.” in November 2018. The Company is a biopharmaceutical company focused on developing and commercializing ONS-5010/LYTENAVA™ (bevacizumab-gamma), an ophthalmic formulation of bevacizumab for use in retinal indications. The Company is based in Iselin, New Jersey.

In May 2024, the Company received Marketing Authorization from the European Commission for ONS-5010/LYTENAVA, an ophthalmic formulation of bevacizumab for the treatment of wet age-related macular degeneration (“AMD”) in the European Union (“EU”). Additionally, in July 2024 the Company also received marketing authorization for ONS-5010/LYTENAVA in the United Kingdom (“UK”) from the UK Medicines and Healthcare products Regulatory Agency (MHRA). ONS-5010/LYTENAVA is the first and only authorized ophthalmic formulation of bevacizumab for use in treating wet AMD in the EU and UK.

In the fourth quarter of 2023, the Company agreed to conduct an additional adequate and well-controlled clinical trial to support its BLA for ONS-5010/LYTENAVA. The Company submitted a Special Protocol Assessment (“SPA”) for the NORSE EIGHT study in December 2023, and in January 2024 the FDA agreed that the protocol, if successful, would satisfy the requirement for a second adequate and well-controlled trial. The company also identified approaches to address the CMC comments in the Complete Response Letter (“CRL”). In November 2024, the Company announced that NORSE EIGHT did not meet the pre-specified non-inferiority endpoint; however, results demonstrated improvements in vision, evidence of biologic activity, and a favorable safety profile, which were further supported by the full week 12 data set. The Company resubmitted the BLA in February 2025. On August 27, 2025, the FDA issued a second CRL citing a single deficiency related to substantial evidence of effectiveness and recommended submission of confirmatory efficacy data, while reaffirming that the NORSE TWO trial met its primary endpoint. Following a Type A meeting in September 2025, the Company resubmitted the BLA on November 3, 2025, and received a Prescription Drug User Fee Act. (“PDUFA”) goal date of December 31, 2025.

2. Liquidity

The Company has incurred recurring losses and negative cash flows from operations since its inception and has an accumulated deficit of $605,709,763 as of September 30, 2025. As of September 30, 2025, the Company had a working capital deficit. Additionally, the Company had $31,452,334 of principal, accrued interest and exit fees due under an unsecured convertible promissory note issued in March 2025 (the “March 2025 Note”), maturing on July 1, 2026. Refer to Note 8 for further details on the March 2025 Note. As a result, there is substantial doubt about the Company’s ability to continue as a going concern. The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

Subsequent to September 30, 2025, the Company sold 10,227,166 shares of common stock under the BTIG ATM Offering and generated $14,931,537 in net proceeds after paying fees to BTIG and other issuance costs of $461,800. Refer to Note 10 for further details on the BTIG ATM Offering.

Management does not believe that the Company’s existing cash and cash equivalents as of September 30, 2025, together with $14,931,537 in net proceeds from the sale of shares of common stock under the BTIG ATM Offering since September 30, 2025, are sufficient to fund the Company’s operations through one year from the Form 10-K filing date. As a result, there is substantial doubt about the Company’s ability to continue as a going concern and additional financing will be needed by the Company to fund its operations in the future, fully commercialize ONS-5010/LYTENAVA and to develop any other product candidates. Management is currently evaluating different strategies to obtain the required funding for future operations, including but not limited to, proceeds from potential licensing and/or marketing arrangements or

collaborations with pharmaceutical or other companies, sale of the development and commercial rights to the Company’s drug product candidates in regions outside of the United States the issuance of additional debt, the issuance of equity securities, including accessing capital through at-the-market offerings (refer to Note 10 for further details), and revenues from product sales. There can be no assurance that any of these future funding efforts will be successful. The Company’s consolidated financial statements do not include any adjustments that might be necessary if it is unable to continue as a going concern.

The Company’s future operations are highly dependent on a combination of factors, including: (i) the timely and successful completion of additional financing discussed above; (ii) the Company’s ability to successfully commercialize ONS-5010/LYTENAVA, including executing marketing arrangements or completing revenue-generating partnerships with other companies; (iii) the success of its research and development; (iv) the development of competitive therapies by other biotechnology and pharmaceutical companies; and, ultimately, (v) regulatory approval and market acceptance of the Company’s proposed future products.

3. Basis of Presentation and Summary of Significant Accounting Policies

Basis of presentation

The accompanying consolidated financial statements have been prepared in conformity with United States generally accepted accounting principles (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). The accompanying consolidated financial statements include the accounts of Outlook Therapeutics Pty Ltd (incorporated in Australia), Outlook Therapeutics NL B.V. (incorporated in the Netherlands), Outlook Therapeutics CH GmbH (incorporated in Switzerland), and Outlook Therapeutics DE GmbH (incorporated in Germany), the Company’s wholly owned subsidiaries (the “Subsidiaries”). All intercompany accounts and transactions have been eliminated in consolidation. The Company has determined the functional currency of the Subsidiaries to be the United States dollar. The Company translates assets and liabilities of its foreign operations at exchange rates in effect at the balance sheet date. The Company records remeasurement gains and losses on monetary assets and liabilities, such as incentive and tax receivables and accounts payables, which are not in the functional currency of the operation. These remeasurement gains and losses are recorded in the consolidated statements of operations as they occur.

Cash and cash equivalents

Cash and cash equivalents include cash-on-hand and demand deposits with financial institutions and other short-term investments with maturities of less than three months when acquired and convertible to known cash amounts. At September 30, 2025 and 2024, the Company’s cash equivalents consist of a money market account.

Equity method investment

The Company accounts for equity investments where it owns a non-controlling interest, but has the ability to exercise significant influence, under the equity method of accounting. Under the equity method of accounting, the original cost of the investment is adjusted for the Company’s share of equity in the earnings or loss of the equity investee and reduced by dividends and distributions of capital received, unless the fair value option is elected, in which case the investment balance is marked to fair value each reporting period and the impact of changes in fair value of the equity investment are reported in earnings. The Company has not elected the fair value option. The Company assesses its investment for other-than-temporary impairment when events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable and recognize an impairment loss to adjust the investment to its then-current fair value.

Use of estimates

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual

results could differ from those estimates. Due to the uncertainty of factors surrounding the estimates or judgments used in the preparation of the consolidated financial statements, actual results may materially vary from these estimates. Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary.

Revenue recognition

The Company recognizes revenue from sales of a single product, LYTENAVA (bevacizumab gamma) (the “Product”) in accordance with ASC Topic 606 –Revenue from Contracts with Customers. LYTENAVA (bevacizumab gamma) became available for commercial sale and shipment to patients in Europe in fiscal year 2025. The Company sells the Product to several customers who are pharmaceutical wholesalers/distributors who in turn sell the Product directly to clinics, hospitals, and pharmacies. Revenue is recognized as the Product is physically delivered to the customers.

Gross product sales are reduced by corresponding Gross-to-Net (“GTN”) estimates using the expected value method, resulting in the Company’s reported “Revenues, net” in the accompanying consolidated statements of operations. Revenues, net reflects the amount the Company ultimately expects to realize in net cash proceeds, taking into account the current period gross sales and related cash receipts and the subsequent cash disbursements on these sales that the Company estimates for the various GTN categories discussed below. The GTN estimates are based upon information received from external sources, such as written or oral information obtained from customers with respect to their period-end inventory levels and sales to end-users during the period, in combination with management’s informed judgments. Due to the inherent uncertainty of these estimates, the actual amount of product returns, rebates and distribution fees may be materially above or below the amount estimated. The variance between actual amounts and estimated amounts may result in prospective adjustments to the reported net product revenue.

Each of the GTN estimate categories are discussed below:

Accounts receivable

As of September 30, 2025, the Company hadno allowance for credit losses. An allowance for credit losses is determined based on the Company's assessment of the creditworthiness and financial condition of its customers, aging of receivables, as well as the general economic environment. Any allowance would reduce the net receivables to the amount that is expected to be collected.

Inventory

The Company values inventory at the lower of cost or net realizable value, computed on a weighted average basis. The Company analyzes its inventory levels quarterly for obsolescence and, if required, adjusts inventory to its net realizable value if the cost basis of inventory is in excess of its expected net realizable value, or for quantities in excess of expected demand.

Upon the initiation of production for the first commercial batches of drug product in October 2024, the Company began capitalizing the purchases of saleable inventory of the product from suppliers. The Company expenses prelaunch inventory as research and development expense in the period incurred unless objective and persuasive evidence exists that regulatory approval and subsequent commercialization of a product candidate is probable and where the Company also expects the

future economic benefit from the sales of the product candidate to be realized. There were no costs related to prelaunch inventory included in inventory as of September 30, 2025, and 2024.

Fair value of financial instruments

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

At September 30, 2025 and 2024, the Company’s financial instruments included cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, unsecured convertible promissory note and warrant liabilities. The carrying amount of cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses approximates fair value due to the short-term maturities of these instruments.

Fair Value Option

The Company elected the fair value option to account for both the December 2022 Note, defined in Note 8, and March 2025 Note. Refer to Note 8 for further details on these financial instruments.

Leases

At lease commencement, the Company records a lease liability based on the present value of lease payments over the expected lease term including any options to extend the lease that the Company is reasonably certain to exercise. The Company calculates the present value of lease payments using an incremental borrowing rate as the Company’s leases do not provide an implicit interest rate. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. At the lease commencement date, the Company records a corresponding right-of-use lease asset based on the lease liability, adjusted for any lease incentives received and any initial direct costs paid to the lessor prior to the lease commencement date. The Company may enter into leases with an initial term of 12 months or less (“Short-Term Leases”). For Short-Term Leases, the Company records the rent expense on a straight-line basis and does not record the leases on the consolidated balance sheet.

After lease commencement, the Company measures its leases as follows: (i) the lease liability based on the present value of the remaining lease payments using the discount rate determined at lease commencement and (ii) the right-of-use lease asset based on the re-measured lease liability, adjusted for any unamortized lease incentives received, any unamortized initial direct costs and the cumulative difference between rent expense and amounts paid under the lease agreement. Any

lease incentives received, and any initial direct costs incurred are amortized on a straight-line basis over the expected lease term. Rent expense is recorded on a straight-line basis over the expected lease term.

Stock-based compensation

The Company measures equity classified stock-based awards based on the estimated fair value on the date of grant and recognizes compensation expense of those awards on a straight-line basis over the requisite service period, which is generally the vesting period of the respective award. The Company accounts for forfeitures of stock option awards as they occur.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option pricing model, which is described more fully in Note 11. The fair value of each restricted stock award is measured as the fair value per share of the Company’s common stock on the date of grant.

Research and development

Research and development costs are expensed as incurred and consist primarily of funds paid to third parties for the provision of services for product candidate development, clinical and preclinical development and related supply and manufacturing costs, and regulatory compliance costs. At the end of the reporting period, the Company compares payments made to third-party service providers to the estimated progress toward completion of the research or development objectives. Such estimates are subject to change as additional information becomes available. Depending on the timing of payments to the service providers and the progress that the Company estimates has been made as a result of the service provided, the Company may record net prepaid or accrued expense relating to these costs.

Upfront milestone payments made to third parties who perform research and development services on the Company’s behalf are expensed as services are rendered. Costs incurred in obtaining technology licenses are charged to research and development expense as acquired in-process research and development if the technology licensed has not reached technological feasibility and has no alternative future use.

Income taxes

The Company accounts for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded to the extent it is more likely than not that some portion or all of the deferred tax assets will not be realized.

Segment reporting

The Company hasone reportable segment which consists of the development and commercialization of ONS-5010/LYTENAVA, an ophthalmic formulation of bevacizumab for the treatment of wet AMD. The Company’s chief operating decision maker (“CODM”) is the chief executive officer. For additional information regarding the Company’s reportable segments, refer to Note 14 – Segment Information.

Net loss per share

Basic net loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during each period. Diluted net loss per share of common stock includes the effect, if any, from the potential exercise or conversion of securities, such as convertible debt, warrants, performance-based stock options and units, and stock options using the treasury stock method, which would result in the issuance of incremental shares of common stock.

During the years ended September 30, 2025, and 2024, the Company incurred a net loss. As a result, all potentially dilutive securities were considered anti-dilutive and were excluded from the calculation of diluted Earnings per share (“EPS”). Therefore, basic and diluted EPS are the same for such periods.

The following potentially dilutive securities (in common stock equivalents) have been excluded from the computation of diluted weighted-average shares outstanding for the years ended September 30, 2025, and 2024, as they would be antidilutive:

Recently issued accounting pronouncements

In November 2023, the FASB issued ASU 2023-07,Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07, which is applicable to entities with a single reportable segment and will primarily require enhanced disclosures about significant segment expenses and enhanced disclosures in interim periods. The guidance in ASU 2023-07 will be applied retrospectively and is effective for annual reporting periods in fiscal years beginning after December 15, 2023 and interim reporting periods in fiscal years beginning after December 31, 2024, with early adoption permitted. The Company adopted ASU 2023-07 during fiscal year 2025, as the standard became effective for public entities for fiscal years beginning after December 15, 2023. For further details regarding the adoption and its impact, refer to the discussion above within Notes 3 and 14.

In December 2023, the FASB issued ASU 2023-09,Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 which is intended to improve income tax disclosure requirements by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) the disaggregation of income taxes paid by jurisdiction. The guidance makes several other changes to the income tax disclosure requirements. The guidance in ASU 2023-09 will be effective for annual reporting periods in fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact that the adoption of ASU 2023-09 will have on its consolidated financial statements and disclosures.

In November 2024, the FASB issued ASU 2024-03,Disaggregation of Income Statement Expenses. ASU 2024-03 requires additional disclosure of specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The requirements will be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact that the adoption of ASU 2024-03 will have on its consolidated financial statements and disclosures.

4. Fair Value Measurements

The following table presents the Company’s liabilities that are measured at fair value on a recurring basis:

The table presented below is a summary of changes in the fair value of the Company’s Level 3 valuation for the warrant liability and the unsecured convertible promissory notes for the years ended September 30, 2025 and 2024:

Unsecured convertible promissory notes

As further described in Note 8, the Company elected the fair value option to account for the unsecured convertible promissory notes. The fair value of these instruments is estimated using a binomial lattice model, which evaluates the

payouts under hold, convert or call decisions. Significant estimates in the binomial lattice model include the Company’s stock price, volatility, risk-free rate of return, and credit-adjusted discount rate.

The fair values of the unsecured convertible promissory notes as of September 30, 2025 and 2024 were estimated using a binomial lattice model with the following assumptions:

Common stock warrants

The warrants related to the Note and Warrant Purchase Agreement dated December 22, 2017 are classified as liabilities as the warrants include cash settlement features at the option of the holders under certain circumstances. These warrants expired during the fiscal year ended September 30, 2025. The warrants issued in connection with private placements that closed on March 18, 2024 and April 15, 2024 are classified as liabilities as the Company assessed that they are not indexed to the Company’s own stock and must be classified as liabilities. During the year ended September 30, 2025, the Company reclassified the warrant liability balance of $13,262,801 into additional paid in capital upon the exercise of certain of the private placement warrants. Refer to Note 10 for further details on warrants exercised pursuant to the warrant inducement transaction.

The above warrant liabilities are revalued each reporting period with the change in fair values recorded in the accompanying consolidated statements of operations until the warrants are exercised or expire. The fair values of the warrant liabilities are estimated using the Black-Scholes option pricing model using the following weighted average assumptions:

6. Equity Method Investment

In connection with the execution of a stock purchase agreement with Syntone Ventures LLC (“Syntone Ventures”), the United States based affiliate of Syntone Technologies Group Co. Ltd. (“Syntone PRC”) on May 22, 2020, the Company

and Syntone PRC entered into a joint venture agreement pursuant to which they agreed to form a People’s Republic of China (“PRC”) joint venture, Beijing Syntone Biopharma Ltd (“Syntone JV”), that is 80% owned by Syntone PRC and 20% owned by the Company. As the Company can exert significant influence over, but does not control, Syntone JV’s operations through voting rights or representation on Syntone JV’s board of directors, the Company accounts for this investment using the equity method of accounting. Upon formation of Syntone JV in April 2021, the Company entered into a royalty-free license with Syntone JV for the development, commercialization and manufacture of ONS-5010/LYTENAVA in the greater China market, which includes Hong Kong, Taiwan and Macau.

The Company made the initial investment of $900,000 in June 2020 and is committed to making capital contributions to Syntone JV of approximately $2,100,000, based upon the development plan contemplated in the license agreement. The maximum exposure to a loss as a result of the Company’s involvement in Syntone JV is limited to the initial investment and the future capital contributions totaling approximately $2,100,000.

7. Accrued Expenses

Accrued expenses consists of:

In connection with workforce reductions, during the year ended September 30, 2025, the Company recognized $2,894,191 in severance related charges consisting of cash-based expenses related to employee severance and notice period payments, benefits and related costs. In addition, during the year ended September 30, 2025, the Company recorded a non-cash expense totaling $2,201,373 related to stock-based compensation in connection with the acceleration of equity awards for the former Chief Executive Officer and Chief Commercial Officer. The Company made total cash payments related to severance and related charges of $1,303,356 during the year ended September 30, 2025.

8. Debt

Debt consists of:

December 2022 Note

On December 22, 2022, the Company entered into a Securities Purchase Agreement and issued an unsecured promissory note (the “December 2022 Note”) with a face amount of $31,820,000 to Streeterville Capital, LLC (the “Lender”), the holder of the Company’s unsecured promissory note issued in November 2021 (the “November 2021 Note”). The December 2022 Note had an original issue discount of $1,820,000. The Company received net proceeds of $18,052,461 upon the closing on December 28, 2022 after deducting the Lender’s transaction costs in connection with the issuance and a full payment of the remaining outstanding principal and accrued interest on the November 2021 Note.

In December 2023, the Company extended the maturity of the December 2022 Note from January 1, 2024 to April 1, 2024. The Company incurred a $475,000 extension fee, which was expensed and included in interest expense in the consolidated statement of operations for the year ending September 30, 2024.

On January 22, 2024, the Company entered into an amendment to the December 2022 Note (the “Note Amendment”) with the Lender, which became effective on April 1, 2024 after satisfaction of certain conditions, including various required stockholder approvals and the closing of the private placement on March 18, 2024. The maturity of the December 2022 Note was extended to July 1, 2025. An extension fee of $2,681,847 (calculated as 7.5% of the outstanding balance of the December 2022 Note) was added to the outstanding balance on March 18, 2024. The extension fee was included in interest expense in the consolidated statement of operations for the year ended September 30, 2024.

During the year ended September 30, 2024, an aggregate of principal and accrued interest totaling $11,250,000 of the December 2022 Note was converted into 1,607,093 shares of the Company’s common stock.

The Company elected to account for the December 2022 Note at fair value (Note 4) and was not required to bifurcate the conversion option as a derivative and as a result the original issue discount of $1,820,000 and debt issuance costs were written off upon election to fair value and accounted for as interest. During the year ended September 30, 2024, the Company recognized $3,156,847 of interest expense related to extension fees.

On March 13, 2025, the Company used the proceeds from the March 2025 Note to pay off the December 2022 Note.

March 2025 Note

On March 13, 2025, the Company issued the March 2025 Note for $33,100,000 to Avondale Capital, LLC (“Avondale”) pursuant to a Securities Purchase Agreement (“Avondale SPA”) dated January 31, 2025. Certain terms of the March 2025 Note were approved at the Company’s annual meeting of stockholders on March 11, 2025, and the Company used the proceeds from the March 2025 Note to pay off the December 2022 Note.

The March 2025 Note bears interest at theprime rate plus 3% (subject to a floor of 9.5%), is scheduled to mature on July 1, 2026, and is convertible into common stock. The Company must repay at least $3,000,000 (by cash or conversions into common stock) of the outstanding balance on the March 2025 Note each quarter starting in the second calendar quarter of 2025 (subject to adjustments for conversions and to payment of a 7.5% exit fee) (the “Quarterly Debt Reduction Obligations”). Any amount converted by Avondale during a given calendar quarter in excess of the Quarterly Debt Reduction Obligations will be credited toward meeting the Quarterly Debt Reduction Obligations for the next quarter or quarters. During the year ended September 30, 2025, Avondale converted $2,525,000 of principal and accrued interest under the March 2025 Note into shares of common stock. In addition, the Company made cash payments totaling $3,475,000. These transactions were applied toward the Quarterly Debt Reduction Obligations and exit fees for the year ended September 30, 2025.

Avondale has the right to convert all or any portion of the outstanding balance under the March 2025 Note into shares of common stock, calculated by dividing the amount of the March 2025 Note being converted by the Conversion Price (as defined below). Furthermore, the Company retains the right to convert any portion of the outstanding balance under the March 2025 Note into shares of common stock at the Conversion Price, provided certain conditions are met at the time of conversion, including, but not limited to, the condition that the daily volume-weighted average price of the Company’s common stock on Nasdaq equals or exceeds $3.00 per share (subject to adjustments for stock splits and combinations) for

a continuous period of 30 trading days, and that the median daily dollar trading volume during the preceding 30 consecutive trading day period meets or exceeds $1,000,000. The Company reserves the right to make payments (i) in cash, (ii) in shares of common stock, calculated as the applicable payment amount divided by the Conversion Price, or (iii) a combination of both cash and shares of common stock. Any cash payments made by the Company, including prepayments or payments made at maturity, will incur an additional fee of 7.5%.

The March 2025 Note stipulates that the Company shall not permit any conversion of the March 2025 Note if, following such conversion, Avondale and its affiliates would beneficially own shares of common stock exceeding 4.99% of the total number of outstanding shares as of that date (the “Beneficial Ownership Limitation”). However, this limitation shall increase to 9.99% when the Company’s market capitalization falls below $25,000,000. Avondale may, by written notice to the Company, adjust the Beneficial Ownership Limitation for itself, though any such adjustment will not take effect until the 61st day after such notice is received.

In the event that specific occurrences outlined in the March 2025 Note transpire—such as the Company’s failure to fulfill payment obligations, non-compliance with the Quarterly Debt Reduction Obligations, insolvency or bankruptcy events, breaches of covenants in the Avondale SPA and the March 2025 Note, and unauthorized transactions without Avondale's consent (collectively referred to as “Trigger Events”)—Avondale reserves the right to increase the balance of the March 2025 Note by 10% in the case of a Major Trigger Event (as defined in the March 2025 Note) and by 5% for a Minor Trigger Event (as defined in the March 2025 Note). Should any Trigger Event persist without resolution forten trading days following written notification from Avondale, this will constitute an event of default (such event, an “Event of Default”). Upon an event of default, Avondale may accelerate the March 2025 Note, resulting in all amounts becoming immediately due and payable, with interest accruing at a rate of 22% per annum until full payment is made.

Under the terms of the March 2025 Note, the “Conversion Price” is defined as $2.26 per share prior to a Major Trigger Event (subject to adjustments for stock splits and combinations). Following a Major Trigger Event, the Conversion Price will be the lesser of (i) $2.26 per share (subject to adjustments) or (ii)90% of the lowest closing bid price over thethree trading days preceding the conversion notice. Furthermore, if the Conversion Price falls below $0.404 per share (subject to adjustments), the Company will be required to fulfill a conversion notice from Avondale in cash.

The Company elected to account for the March 2025 Note at fair value (Note 4) and was not required to bifurcate the conversion option as a derivative and as a result the debt issuance costs were accounted for as interest upon election to account for the instrument at fair value. During the year ended September 30, 2025, the Company recorded $40,686 of interest expense associated with the debt issuance costs for the March 2025 Note. During the year ended September 30, 2025, the Company recognized $242,442 of interest expense associated with the exit fees on debt repayments for the March 2025 Note.

9. Commitments and Contingencies

Selexis Commercial License Agreements

In April 2013, the Company entered into commercial license agreements with Selexis for each of the ONS-3010, ONS-1045 and ONS-1050 biosimilar product candidates (which agreements were subsequently amended on May 21, 2014). Under the terms of each commercial license agreement, the Company acquired a non-exclusive worldwide license under the Selexis Technology to use the applicable Selexis expression technology along with the resulting Selexis materials/cell lines, each developed under the research license, to manufacture and commercialize licensed and final products, with a limited right to sublicense.

The Company paid an upfront licensing fee to Selexis for each commercial license and also agreed to pay a fixed milestone payment for each licensed product. In addition, the Company is required to pay a low single-digit royalty on a final product-by-final product and country-by-country basis, based on worldwide net sales of such final products by the Company or any of the Company’s affiliates or sublicensees during the royalty term. The royalty term for each final product in each country is the period commencing from the first commercial sale of the applicable final product in the applicable country and ending on the expiration of the specified patent coverage. At any time during the term, the Company has the right to

terminate its royalty payment obligation by providing written notice to Selexis and paying Selexis a royalty termination fee.

Each of the Company’s commercial agreements with Selexis will expire upon the expiration of all applicable Selexis patent rights. Either party may terminate the related agreement in the event of an uncured material breach by the other party or in the event the other party becomes subject to specified bankruptcy, winding up or similar circumstances. Either party may also terminate the related agreement under designated circumstances if the Selexis Technology infringes third-party intellectual property rights. In addition, the Company has the right to terminate each of the commercial agreements at any time at its convenience; however, with respect to the agreements relating to ONS-3010 and ONS-1045, this right is subject to the licensee’s consent pursuant to a corresponding letter the Company executed in conjunction with the standby agreement entered into between Selexis and Laboratories Liomont, S.A. de C.V. (“Liomont”) in November 2014.

The standby agreement permits Liomont to assume the license under the applicable commercial agreement for Mexico upon specified triggering events involving the Company’s bankruptcy, insolvency or similar circumstances.

Technology License

The Company entered into a technology license agreement with Selexis, under which a milestone payment of $365,195 (converted from Swiss Francs to United States dollars) was due upon achievement of certain commercial and clinical milestones. The milestone payment was accrued for as of September 30, 2025 and payment was made in fiscal year 2026. In addition, the agreement requires the Company to pay a single digit royalty on net sales by the Company utilizing such technology. The Company also has the contractual right to buy out the royalty payments at a future date.

Purchase Commitments

As of September 30, 2025, the Company had outstanding contractual commitments of approximately $955,050, primarily related to fill-finish manufacturing services for ONS-5010/LYTENAVA to be performed by its contract manufacturers.

Litigation

On November 3, 2023, a securities class action lawsuit was filed against the Company and certain of its officers in the United States District Court for the District of New Jersey. The class action complaint alleges violations of the Securities Exchange Act of 1934, as amended, or the Exchange Act, in connection with allegedly false and misleading statements made by the Company related to the Company’s BLA during the period from August 3, 2021 through August 29, 2023. The complaint alleges, among other things, that the Company violated Sections 10(b) and 20(a) of the Exchange Act and SEC Rule 10b-5 by failing to disclose that there was an alleged lack of evidence supporting ONS-5010/LYTENAVA as a treatment for wet AMD and that the Company and/or their manufacturing partner had deficient CMC controls for ONS-5010/LYTENAVA, which remained unresolved at the time the Company’s BLA was re-submitted to the FDA and, as a result, the FDA was unlikely to approve the Company’s BLA, and that the Company’s stock price dropped when such information was disclosed. The plaintiffs in the class action complaint seek damages and interest, and an award of reasonable costs, including attorneys’ fees. The defendants’ motion to dismiss plaintiffs’ second amended complaint is currently pending before the court.

On October 10, 2024, certain of the company’s officers and directors were named as defendants in a shareholder derivative action filed in the District Court of the District of Delaware. The derivative complaint alleges that defendants breached their fiduciary duties by causing and/or allowing the Company to violate federal securities laws based on the same alleged misstatements as the securities class action. The derivative complaint also alleges defendants violated Section 14(a) of the Exchange Act, as well as claims for contribution, unjust enrichment, and waste of corporate assets. The derivative complaint seeks unspecified damages, corporate governance reforms, restitution, contribution, attorneys’ fees, and other costs. The derivative action is currently stayed, pending the final resolution of the securities class action pending in the United States District Court for the District of New Jersey.

The pending lawsuits and any other related lawsuits are subject to inherent uncertainties, and the actual defense and disposition costs will depend upon many unknown factors. The outcome of the pending lawsuits and any other related

lawsuits is necessarily uncertain. The Company could be forced to expend significant resources in the defense of the pending lawsuits and any additional lawsuits, and the Company may not prevail. In addition, the Company may incur substantial legal fees and costs in connection with such lawsuits. The Company currently is not able to estimate the possible cost to it from these matters, as the pending lawsuits are currently at an early stage, and the Company cannot be certain how long it may take to resolve the pending lawsuits or the possible amount of any damages that the Company may be required to pay. Such amounts could be material to the Company’s financial statements if it does not prevail in the defense of the pending lawsuits and any other related lawsuits, or even if it does prevail. The Company has not established any reserve for any potential liability relating to the pending lawsuits and any other related lawsuits. It is possible that the Company could, in the future, incur judgments or enter into settlements of claims for monetary damages.

10. Stockholders’ Equity

Common stock

On March 7, 2024, following receipt of stockholder approval at the Company’s 2024 annual meeting of stockholders, the number of authorized shares of common stock under the Company’s Certificate of Incorporation was increased from 21,250,000 shares to 60,000,000 shares.

On March 11, 2025, following receipt of stockholder approval at the Company’s 2025 annual meeting of stockholders, the number of authorized shares of common stock under the Company’s Certificate of Incorporation was increased from 60,000,000 shares to 260,000,000 shares.

On March 18, 2024, in a private placement (the “Private Placement”) pursuant to a securities purchase agreement entered in January 2024 with certain institutional and accredited investors, including GMS Ventures and Investments (“GMS Ventures”), the Company’s largest stockholder, the Company issued an aggregate of 8,571,423 shares of common stock and warrants to purchase an aggregate of 12,857,133 shares of common stock at a purchase price per share of $7.00 per share (the “Private Placement Warrants”) and accompanying warrant to purchase one andone-half shares of common stock for $55,498,311 in net proceeds after payment of placement agent fees and other offering costs. GMS Ventures purchased an aggregate of 2,305,714 shares of common stock and warrants to purchase an aggregate of 3,458,571 shares of common stock in the Private Placement. The Warrants have an exercise price of $7.70 per share of common stock and will expire on March 18, 2029.

On April 15, 2024, in a private placement with Syntone pursuant to a securities purchase agreement entered into in January 2024 (the “Syntone Private Placement”), the Company issued 714,286 shares of common stock and accompanying warrants to purchase 1,071,429 shares of common stock for $4,835,371 in net proceeds on substantially the same terms as those in the Private Placement. The warrants have an exercise price of $7.70 per share of common stock and will expire on April 15, 2029.

On January 16, 2025, the Company executed warrant inducement agreements with GMS Ventures and certain other holders of Private Placement Warrants to exercise warrants for 7,074,637 shares of common stock. Concurrently, the Company entered into a warrant inducement transaction with Syntone to exercise warrants for 1,071,429 shares of common stock issued under the Syntone Warrant Inducement Transaction, defined below. For further details on the warrant inducement

agreements, refer to the sections on the Warrant Inducement Transaction and the Syntone Warrant Inducement Transaction below.

The Company evaluated the equity classification for the common stock warrants and considered the conditions as prescribed within ASC 815-40,Derivatives and Hedging, Contracts in an Entity’s own Equity (“ASC 815-40”). The Company determined that the warrants did not meet the “fixed for fixed” settlement provision set forth in Step 2 of the indexation guidance and as a result they are not indexed to the Company’s own stock and must be classified as liabilities. The warrants were measured at fair value at issuance and recorded as a liability and will be remeasured to fair value at each subsequent reporting date, with changes in fair value recorded in current earnings. The net proceeds from the Private Placement were allocated first to the warrants at fair value, with the residual amount recorded as common stock at par value. The Company will continue to classify such warrants as liabilities until they are exercised, expire, or are no longer required to be classified as liabilities.

The fair value of the warrants at issuance exceeded the proceeds received from both the Private Placement and the Syntone Private Placement; therefore, no proceeds were allocated to additional paid-in capital. For the year ended September 30, 2024, the aggregate excess of the warrant fair value over the related proceeds was $37,490,012, which was recognized as warrant-related expenses in the consolidated statements of operations.

BTIG, LLC At-the-Market Offering Agreement

On May 16, 2023, the Company entered into an At-the-Market Sales Agreement with BTIG, LLC (“BTIG”), as sales agent (the “BTIG ATM Agreement” or the “BTIG ATM Offering”), under which the Company may issue and sell shares of its common stock having an aggregate offering price of up to $100,000,000 from time to time through BTIG. The Company incurred financing costs of $353,688, which were capitalized and are being reclassified to additional paid in capital on a pro rata basis when the Company sells common stock under the BTIG ATM Offering. As of September 30, 2025, $282,420 of such deferred costs are included in other assets on the consolidated balance sheets.

Under the BTIG ATM Agreement, the Company pays BTIG a commission equal to 3.0% of the aggregate gross proceeds of any sales of common stock under the BTIG ATM Agreement. The offering of common stock pursuant to the BTIG ATM Agreement will terminate upon the earlier of (i) the sale of all common stock subject to the BTIG ATM Agreement or (ii) termination of the BTIG ATM Agreement in accordance with its terms.

During the year ended September 30, 2024, no shares of common stock were sold under the BTIG ATM Offering. During the year ended September 30, 2025, the Company sold 8,681,852 shares of common stock under the BTIG ATM Offering and generated $13,461,540 in net proceeds after paying fees to BTIG and other issuance costs of $416,337.

Warrant Inducement Transaction

On January 16, 2025, the Company entered into warrant exercise inducement offer letter agreements with GMS Ventures and certain other holders of Private Placement Warrants, pursuant to which the holders agreed to exercise their existing warrants (“Existing Warrants”) for an aggregate of 7,074,637 shares of common stock at a reduced exercise price of $2.51 per share. In exchange, the Company issuedtwo new inducement warrants for each Existing Warrant exercised (“Inducement Warrants”), which are exercisable for an aggregate of up to 14,149,274 additional shares of common stock (the “Inducement Warrant Shares”) at an exercise price of $2.26 per share (collectively, the “Warrant Inducement Transaction”). The Company received net proceeds of $16,590,968 after capital markets advisory fees and offering costs, from the Warrant Inducement Transaction. On the modification date, the Company remeasured the warrants at the reduced exercise price and recognized a $1,692,779 inducement charge in the consolidated statements of operations for the year ended September 30, 2025. Upon the exercise of these liability classified warrants, the Company reclassed the warrant liability balance of $13,262,801 into additional paid in capital.

In connection with the Warrant Inducement Transaction, half of the Inducement Warrants (the “Tranche A Inducement Warrants”), representing warrants to purchase up to 7,074,637 shares of common stock were exercisable immediately and expire on January 17, 2030. The remaining Inducement Warrants (the “Tranche B Inducement Warrants”) became exercisable upon the effective date of an amendment to the Company’s Certificate of Incorporation to increase the number of authorized shares of common stock. The Tranche A and B Inducement Warrants are considered equity-classified

warrants. Given that the Tranche A and Tranche B Inducement Warrants were issued concurrently with the exercise of the Existing Warrants, the Company recorded an inducement charge in the consolidated statements of operations in the amount of $27,421,002 for the year ended September 30, 2025.

Syntone Warrant Inducement Transaction

Concurrently with the Warrant Inducement Transaction, the Company entered into a warrant exercise inducement offer letter agreement with Syntone, pursuant to which Syntone agreed to exercise existing warrants (“Existing Syntone Warrants”) for an aggregate of 1,071,429 shares of common stock at a reduced exercise price of $2.51 per share. In exchange, the Company agreed to issuetwo new inducement warrants for each Existing Syntone Warrant exercised (the "Syntone Inducement Warrants”), which will be exercisable for up to 2,142,858 shares of common stock (the “Syntone Inducement Warrant Shares”) at an exercise price of $2.26 per share (the “Syntone Warrant Inducement Transaction”). The closing of the Syntone Warrant Inducement Transaction is subject to receipt of certain regulatory approvals. On the modification date, the Company remeasured the warrants at the reduced exercise price and recognized a $255,278 inducement charge in the consolidated statements of operations for the year ended September 30, 2025. As of the date of this filing, Syntone has not received regulatory approval and, thus, the Company has not yet received the proceeds from the exercise of the Existing Syntone Warrants. There can be no assurance that Syntone will receive the requisite regulatory approval in the near term or at all, and the Company may never receive the proceeds from the exercise of the Existing Syntone Warrants, or issue, or receive proceeds from the exercise of, the Syntone Inducement Warrants. In connection with the Syntone Warrant Inducement Transaction, half of the Syntone Inducement Warrants (the “Syntone Tranche A Inducement Warrants”) will be immediately exercisable upon receipt of certain regulatory approvals and will expire on thefive-year anniversary of the date of issuance. The remaining Syntone Inducement Warrants (the “Syntone Tranche B Inducement Warrants”) will be exercisable upon receipt of certain regulatory approvals. As of the date of this filing, the Syntone Tranche A and Tranche B Inducement Warrants have not been issued. Given that the Company agreed to issue Syntone Tranche A and Tranche B Inducement Warrants in exchange for Syntone’s agreement to exercise existing warrants at a reduced exercise price, the Company recorded an inducement charge in the consolidated statements of operations in the amount of $4,152,815 for the year ended September 30, 2025.

The fair value per share of the Existing Warrants and Existing Syntone Warrants was determined using the Black-Scholes option pricing model. Prior to the modification of the warrant exercise price, the fair value per share was $1.64, based on a risk-free interest rate of 4.34%, a remaining contractual term of 4.2 years, expected volatility of 136.0%, a dividend yield of 0%, and a stock price of $2.23. On the modification date, the fair value per share was $1.88, calculated using the same assumptions.

The fair value per share of the Tranche A Inducement Warrants, Tranche B Inducement Warrants, Syntone Tranche A and B Inducement Warrants of $1.96 was estimated using the Black-Scholes option pricing model using the following weighted average assumptions: a risk-free interest rate of 4.39%, a contractual term of 5 years, an expected volatility of 130.2%, an anticipated annual dividend yield of 0%, and a stock price of $2.23.

Underwritten Public Offering

On May 27, 2025, the Company completed an underwritten public offering (the “Public Offering”) of 9,285,714 shares of common stock and warrants to purchase an aggregate of 18,571,428 shares of common stock pursuant to an underwriting agreement dated May 22, 2025, between the Company and BTIG. The combined price for each share of common stock and accompanying warrant to purchasetwo shares of common stock was $1.40. The Company received aggregate net proceeds of $11,617,407, after payment of placement agent fees and other offering costs. GMS Ventures purchased an aggregate of 4,285,714 shares of common stock and warrants to purchase an aggregate of 8,571,428 shares of common stock in the Public Offering. The warrants have an exercise price of $1.40 per share of common stock and will expire on May 27, 2030.

Common stock warrants

As of September 30, 2025, the Company had the following warrants outstanding to acquire shares of its common stock:

A holder of warrants may not exercise the warrant if the holder, together with its affiliates, would beneficially own more than a specified percentage of the outstanding common stock (4.99%,9.99% or 19.99%, as applicable), immediately after giving effect to such exercise, which may be increased or decreased at the holders’ option (not to exceed 19.99%), effective 61 days after written notice to the Company. In addition, the Company may require the holders to cash exercise the warrants under certain circumstances as follows: (i) if the daily volume weighted average price (the “VWAP”) of the common stock equals or exceeds $20.00 per share (subject to adjustment in the event of stock splits, combinations or similar events, such as the reverse stock split implemented prior to closing) for 30 consecutive days (the “Stock Price Condition”) at any time after the Company publicly announces topline data from its NORSE EIGHT clinical trial evidencing satisfaction of the trial’s primary endpoints (the “NORSE EIGHT Announcement”), upon the consent of a majority of the members of the Company’s board of directors, the Company may require the holders to exercise up to 20% of the aggregate number of warrants issued to such holder on the issue date; and (ii) the Company may require up to the remainder of the warrants be exercised (A) if the Stock Price Condition is satisfied at any time after the Company publicly announces approval from the FDA of its BLA for ONS-5010/LYTENAVA, upon the consent of a majority of the members of the board of directors or (B) if the Stock Price Condition is satisfied at any time after the NORSE EIGHT Announcement, upon the unanimous consent of the members of the Company’s Board of Directors present at a duly called meeting.

During the year ended September 30, 2025, warrants to purchase an aggregate of 42,460 shares of common stock with a weighted average exercise price of $149.11 expired. In addition, warrants to purchase an aggregate of 7,074,637 shares of common stock with an exercise price of $2.51 related to the Warrant Inducement Transaction, warrants to purchase an aggregate of 3,300,000 shares of common stock with an exercise price of $1.40 generating net proceeds of $4,327,940, and warrants to purchase an aggregate of 522,142 shares of common stock with an exercise price of $2.26 were exercised generating net proceeds of $1,105,444. The Company generated aggregate net proceeds of $22,024,352 from common stock warrants exercised the year ended September 30, 2025 after deducting expenses associated with with such exercises.

11. Stock-Based Compensation

2024 Equity Incentive Plan

In December 2015, the Company adopted the 2015 Equity Incentive Plan (the “2015 Plan”). The 2015 Plan provided for the grant of stock options, stock appreciation rights, restricted stock awards, RSU awards, performance stock awards and other forms of equity compensation to Company employees, directors and consultants. In August 2024, the Company’s stockholders approved the amendment and restatement of the 2015 Plan and, in connection with amending and restating the 2015 Plan, the name of the 2015 Plan was updated to the Outlook Therapeutics, Inc. 2024 Equity Incentive Plan (the “2024 Plan”). The 2024 Plan provides for the grant of stock options, stock appreciation rights, restricted stock awards, RSU awards, performance stock awards and other forms of equity compensation to Company employees, directors and consultants. The aggregate number of shares of common stock authorized for issuance pursuant to the Company’s 2024 Plan is 7,293,901. As of September 30, 2025,4,357,084 shares remained available for grant under the 2024 Plan.

Stock options and RSUs granted under the Company's 2024 Plan generally vest over a period ofone tofour years from the date of grant and, in the case of stock options, have a term of 10 years. The Company recognizes the grant date fair value of each option and share of RSU over its vesting period.

The Company recorded stock-based compensation expense in the following expense categories of its consolidated statements of operations for the years ended September 30, 2025 and 2024:

During the year ended September 30, 2025, the Company capitalized stock-based compensation of $37,991 as part of inventory costs. This amount relates to stock-based compensation expense for employees directly involved in manufacturing activities.

Stock options

The following table summarizes all of the Company’s stock option activity for the year ended September 30, 2025:

The aggregate intrinsic value represents the total amount by which the fair market value of the common stock subject to options exceeds the exercise price of the related options.

The Company estimated the fair value of each stock option award on the grant date using the Black-Scholes option pricing model, wherein expected volatility is based on the Company’s historical volatility. The expected term calculation is based on the “simplified” method described in Staff Accounting Bulletin (“SAB”) No. 107,Share-Based Payment, and SAB No. 110,Share-Based Payment, since the simplified method provides a reasonable estimate in comparison to actual experience. The risk-free interest rate is based on the United States Treasury yield at the date of grant for an instrument

with a maturity that is commensurate with the expected term of the stock options. The dividend yield iszero since the Company has never paid cash dividends on its common stock and has no present intention to pay cash dividends. Options granted under the 2024 Plan generally vest overone tofour years and have a term of 10 years.

The weighted average grant date fair value of the options awarded to employees and directors for the years ended September 30, 2025 and 2024 was $3.30 and $6.04 per option, respectively. The fair value of the options was estimated on the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions:

As of September 30, 2025, there was $2,016,949 of unrecognized compensation expense that is expected to be recognized over a weighted-average period of 0.9 years.

Performance-based stock options

The Company granted certain officers of the Company option awards where vesting was contingent upon meeting certain company-wide performance goals. The performance stock options were granted “at-the-money” and have a term of 10 years.

The fair value of each option grant under the performance share option plan was estimated on the date of grant using the same option valuation model used for non-statutory options above. Compensation expense for performance-based stock options is only recognized when management determines it is probable that the awards will vest.

The following table summarizes all of the Company’s performance-based stock option activity for the year ended September 30, 2025.

During the year ended September 30, 2025, no expense was recognized because the performance conditions were not considered probable of achievement. The assessment was based on the relevant facts and circumstances and therefore no compensation costs were recognized. The fair value of the options was estimated on the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions:

12. Collaboration Arrangements

Syntone Strategic Partnership and PRC Joint Venture

In connection with a stock purchase agreement entered in May 2020 between the Company and Syntone, the Company and Syntone entered into a joint venture agreement pursuant to which they agreed to form a PRC joint venture that will be 80% owned by Syntone and 20% owned by the Company. Upon formation of the PRC joint venture in April 2021, the Company entered into a royalty-free license with the PRC joint venture for the development, commercialization and manufacture of ONS-5010/LYTENAVA in the greater China market, which includes Hong Kong, Taiwan and Macau.

The Company made the initial investment of $900,000 in June 2020. The Company is committed to making up to $2,100,000 in additional capital contributions to the PRC joint venture, based upon the development plan contemplated in the license agreement or on such other terms.

13. Income Taxes

Income tax benefit for the years ended September 30, 2025 and 2024 consists of the following:

A reconciliation of income tax expense (benefit) at the statutory federal income tax rate and income taxes as reflected in the financial statements is as follows:

The tax effects of the temporary differences that gave rise to deferred taxes were as follows:

As of September 30, 2025, the Company had approximately $441.0 million and $243.6 million of United States federal and New Jersey NOLs that will begin to expire in 2030 and 2039, respectively. As of September 30, 2025, the Company had federal and state research and development tax credit carryforwards of $11.6 million and $0.8 million, respectively, available to reduce future tax liabilities which will begin to expire in 2032 and 2033, respectively. As of September 30, 2025, the Company has federal foreign tax credit (“FTC”) carryforwards of $0.1 million available to reduce future tax liabilities which began to expire starting in 2023, of which $1.9 million of the FTC carryforward is included in the balance of unrecognized tax benefits. Realization of the deferred tax asset is contingent on future taxable income and based upon the level of historical losses, management has concluded that the deferred tax asset does not meet the more-likely-than-not threshold for realizability. Accordingly, a full valuation allowance continues to be recorded against the Company’s deferred tax assets as of September 30, 2025 and 2024. The valuation allowance increased by $7.1 million and $19.0 million during the year ended September 30, 2025 and 2024, respectively.

When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely-than-not be realized. The determination as to whether the tax benefit will more-likely-than-not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. The Company recognizes interest and penalties accrued on any unrecognized tax benefits within the provision for income taxes in its consolidated statements of operations.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the United States. The legislation includes significant corporate tax reforms, including the permanent reinstatement of the ability to deduct domestic research and development expenditures as incurred beginning in fiscal 2026, replacing the previous requirement to capitalize and amortize such expenditures over five years. The OBBBA also introduces modifications to the international tax framework, including changes to the foreign-derived intangible income (“FDII”) regime. Under the legislation, FDII is renamed foreign-derived deduction-eligible income (“FDDEI”), with the current FDDEI effective tax rate of 13% maintained through fiscal 2026, followed by a permanent adjustment to a 14% rate beginning in fiscal 2027 (compared to 16% under prior law). The legislation contains multiple effective dates, with certain provisions effective in 2025 and others becoming effective in subsequent years. The effects of OBBBA are not expected to have a material impact relative the financials of the Company.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

The Company expects the remaining $300,000 to be recognized as a tax benefit in the next 12 months. These unrecognized tax benefits, if recognized, would affect the annual effective tax rate. The Company’s income tax returns for the years from 2011 through 2024 remain open for examination by the Internal Revenue Service as well as various states and municipalities.

Due to the change in ownership provisions of the Code, the availability of the Company’s NOL carryforwards may be subject to annual limitations against taxable income in future periods, which could substantially limit the eventual utilization of such carryforwards. The Company has not analyzed the historical or potential impact of its equity financings on beneficial ownership and therefore no determination has been made whether the net operating loss carry forward is subject to any Code Section 382 limitation. To the extent there is a limitation, there would be a reduction in the deferred tax assets with an offsetting reduction in the valuation allowance.

14. Segment Information

Operating segments are components of an enterprise for which discrete financial information is available and reviewed by the chief operating decision maker (“CODM”) to allocate resources and assess performance. The Company hasone reportable segment, which consists of the development and commercialization of ONS-5010/LYTENAVA™, an ophthalmic formulation of bevacizumab for the treatment of wet AMD. The Company’s CODM is its Chief Executive Officer, who evaluates and manages the business on a consolidated basis for purposes of resource allocation and performance assessment.

The accounting policies of the Company’s single segment are the same as those described in the summary of significant accounting policies. To date, the Company has generated insignificant 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. The CODM assesses performance for its segment based on net loss, which is reported on the consolidated statements of operations. The CODM uses budget versus forecasted expense and cash forecast models in making decisions. Such models are reviewed to assess the entity-wide operating results and performance, including how long cash is expected to be sufficient. The measure of segment assets is reported on the consolidated balance sheet as total assets.

The table below summarizes the significant expense categories regularly reviewed by the CODM for the years ended September 30, 2025 and 2024:
