We are a biopharmaceutical company that has developed LYTENAVATM (bevacizumab gamma) as the first and only ophthalmic formulation of bevacizumab approved by the European Commission in the European Union, or EU, and the Medicines and Healthcare products Regulatory Agency, or MHRA, in the United Kingdom, or UK, for use in adults for the treatment of wet age-related macular degeneration, or wet AMD. In June 2025, we launched directly into the initial markets of Germany and the UK and are planning for launches in other EU countries either directly or with a licensing partner. Additionally, we are attempting to receive approval for ONS-5010/LYTENAVA by the U.S. Food and Drug Administration, or FDA, for the use of ONS-5010/LYTENAVA as a treatment for wet AMD in the United States. If approved in the U.S., our goal is to also launch directly in the United States as the first and only approved ophthalmic bevacizumab for the treatment of wet AMD. In addition to Europe and the United States, we may seek approval to launch the product in other markets outside of Europe and the U.S. either directly or with licensing partners.

Bevacizumab is a full-length, humanized anti-VEGF (Vascular Endothelial Growth Factor) recombinant monoclonal antibody, or mAb, that inhibits VEGF and associated angiogenic activity. Prior to the approval of ONS-5010/LYTENAVA in the EU and UK, bevacizumab had only been approved for use in the treatment of various forms of cancer and had not been optimized for use in the treatment of retina diseases. Because there previously were no approved bevacizumab products for the treatment of retinal diseases in the United States and other major markets, we submitted standard biologic therapeutic applications and are not using the biosimilar drug regulatory pathway that would be required if bevacizumab were an approved drug for the targeted disease. Off-label repackaged bevacizumab is a frequently used first-line anti-VEGF treatment in Europe (approximately 2.8 million injections annually) and the United States (approximately 2.7 million injections annually) based on data compiled from various sources (Citeline (2023), Global Data (2023) and Market Scope (2022); ASRS 2024 Membership Survey; Market Scope 2024 US Retina Quarterly Updates; GlobalData: Age-Related Macular Degeneration: Global Drug Forecast and Market Analysis to 2028 (April 2020)). We believe ONS-5010/LYTENAVA has potential to mitigate risks associated with off-label use of unapproved bevacizumab. We believe there is significant opportunity in Europe with a total anti-VEGF retina market estimated to be approximately $3.6 billion, including approximately 1.52 million treated patients and approximately 8.3 million total anti-VEGF units (Global Data (2023); Market Scope (2022); IQVIA MIDAS data Q3 2023; Graefe's Archive for Clinical and Experimental Ophthalmology (2020) 258:503–511).

We agreed to conduct an additional adequate and well-controlled clinical trial following discussions with the FDA in support of our BLA for ONS-5010/LYTENAVA. In December 2023, we submitted a Special Protocol Assessment, or SPA, to the FDA for this study (NORSE EIGHT) seeking confirmation that, if successful, it would address the FDA’s requirement for a second adequate and well-controlled clinical trial to support our planned resubmission of the ONS-5010/LYTENAVA BLA. In January 2024, we received confirmation that the FDA had reviewed and agreed upon the NORSE EIGHT trial protocol pursuant to the SPA. In November 2024, we reported that ONS-5010/LYTENAVA did not meet the pre-specified non-inferiority endpoint at week 8 set forth in the SPA. Analysis of the complete week 12 data set for NORSE EIGHT provided additional evidence of improvement in vision and biological activity. We resubmitted the BLA for ONS-5010/LYTENAVA in February 2025. On August 27, 2025, we received a second CRL from the FDA. This CRL included only one deficiency, for a lack of substantial evidence of effectiveness. In the CRL, the FDA advised that, because ONS-5010 did not meet the primary efficacy endpoint in NORSE EIGHT, it was recommended that confirmatory evidence of efficacy be submitted to support the application for ONS-5010. Additionally, the FDA reiterated that NORSE TWO met its primary endpoint for effectiveness. Following a September 2025 Type A meeting with the FDA, we resubmitted the BLA in October 2025. On December 31, 2025, we reported that we had received a third CRL in which the FDA noted that the additional mechanistic and natural history data information provided in the BLA resubmission does not alter the previous review conclusion that while the one adequate and well-controlled study demonstrated efficacy, and the FDA has again recommended that confirmatory evidence of efficacy be submitted to support the application. However, the FDA did not indicate in the CRL what type of confirmatory evidence would be acceptable. On February 11, 2026, we reported that we have requested a Type A meeting with the FDA to discuss the CRL and potential regulatory pathways for ONS-5010. If approved, we expect to receive 12 years of regulatory exclusivity in the United States.

countries in which we conduct our business, that political, diplomatic, and national security factors can lead to global trade restrictions and changes in trade policies and export regulations that may adversely affect our business and operations. The current international trade and regulatory environment is subject to significant ongoing uncertainty. The United States may continue to announce tariffs affecting a wide range of products and jurisdictions and has indicated an intention to continue developing new trade policies, including with respect to the pharmaceutical industry. In response, certain foreign governments have announced or implemented retaliatory tariffs and other protectionist measures. These developments have created a dynamic and unpredictable trade landscape, which may adversely impact our business, results of operations, financial condition and prospects. Current or future tariffs will result in increased research and development expenses, including with respect to increased costs associated with raw materials, laboratory equipment and research materials and components. In addition, such tariffs will increase our supply chain complexity and could also potentially disrupt our existing supply chain. Trade restrictions and tariffs affecting the import of materials necessary for clinical trials could result in delays to our development timelines. Increased development costs and extended development timelines could place us at a competitive disadvantage compared to companies operating in regions with more favorable trade relationships and could reduce investor confidence, negatively impacting our ability to secure additional financing on favorable terms or at all. In addition, as we continue to expand our commercialization efforts, tariffs and trade restrictions could hinder our ability to establish cost-effective production capabilities, negatively impacting our growth prospects. We currently manufacture ONS-5010/LYTENAVA in the United States, which helps mitigate exposure to global tariff volatility. However, this concentration of manufacturing may adversely affect our pricing and competitiveness in the United Kingdom and European Union.

Current wording

Global uncertainty due to tariffs and global macroeconomic conditions may have a material adverse effect on our commercialization efforts. The global financial markets recently have experienced significant disruptions due to various macroeconomic factors, including, among other things, the impacts of fluctuations in inflation and interest rates, tariffs and trade tensions, and geopolitical instability and uncertainty. If these disruptions and slowdown deepen or persist, we may not be able to access additional capital on favorable terms, or at all, which could in the future negatively affect our ability to pursue our business strategy. There is inherent risk, based on the complex relationships among the U.S. and the countries in which we conduct our business, that political, diplomatic, and national security factors can lead to global trade restrictions and changes in trade policies and export regulations that may adversely affect our business and operations.

During the three months ended December 31, 2025, net revenue was negative $1.2 million, compared to zero for the same period in the prior year. The negative revenue was primarily due to a $1.1 million increase in the returns reserve related to estimated product returns from our UK distributor due to lower-than-forecasted sell-through. We do not anticipate further adjustments for these batches in fiscal 2026. Returns reserves are reviewed quarterly and may be adjusted based on our ongoing assessment of business conditions and distributor-level sales forecasts. In addition, we recognized administrative fees assessed under contractual arrangements with our wholesalers during the three months ended December 31, 2025. When combined with the increase in the returns reserve, these fees contributed to the negative net revenue for the period.

Pursuant to the terms of the March 2025 Note, the occurrence of a Major Trigger Event resulted in (i) an automatic 10% increase to the outstanding balance, effective January 1, 2026, and (ii) an adjustment to the Conversion Price. Following the adjustment, the Conversion Price is equal to the lesser of the fixed conversion price of $2.26 or 90% of the lowest closing bid price during the three trading days immediately preceding the delivery of a conversion notice, provided that the Conversion Price may not be reduced below the contractual floor price of $0.404. During the six months ended March 31, 2026, Avondale converted 6.9 million of principal and accrued interest on the March 2025 Note into 15,057,649 shares of our common stock. As a result of this conversion, the Quarterly Debt Reduction Obligation was satisfied for the quarters ended December 31, 2025 and March 31, 2026. For additional information regarding the March 2025 Note, refer to Note 7 to the unaudited interim consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Previous wording

We evaluated whether there are conditions or events considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern. We do not believe that the existing cash and cash equivalents as of December 31, 2025, together with $2.4 million in net proceeds from the sale of shares of common stock under the ATM Agreement since December 31, 2025, are sufficient to fund the Company’s operations through one year from the date of this Quarterly Report on Form 10-Q. As a result, there is substantial doubt about the Company’s ability to continue as a going concern. Our unaudited interim consolidated financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

We do not believe that the existing cash and cash equivalents as of March 31, 2026, together with $5.0 million in gross proceeds from the Registered Direct Stock Offering completed in April 2026, are sufficient to fund our operations through one year from the date of this Quarterly Report on Form 10-Q.

Previous wording

During the three months ended December 31, 2025, we used $14.9 million of cash in operating activities resulting primarily from our net loss of $23.1 million. This use of cash was partially offset by $10.5 million of non-cash items such as stock-based compensation, loss from change in fair value of promissory notes, warrant inducement expenses, gain from change in fair value of warrant liability, loss on equity method investment and amortization expense. The net cash outflow of $2.4 million from changes in operating assets and liabilities was driven primarily by a $3.2 million decrease in accounts payable and accrued expenses due to payment timing, and a $0.4 million increase in prepaid expenses related to ONS‑5010/LYTENAVA development activities. These outflows were partially offset by a $1.4 million decrease in receivables resulting from collections and the impact of the higher product returns reserve.

Current wording

During the six months ended March 31, 2026, we used $22.7 million of cash in operating activities resulting primarily from our net loss of $27.5 million. This use of cash was partially offset by $1.6 million of non-cash items such as stock-based compensation, loss from change in fair value of promissory notes, gain from change in fair value of warrant liability, loss on equity method investment and amortization expense. The net cash inflow of $3.0 million from changes in operating assets and liabilities was driven primarily by a $6.9 million increase in accounts payable and accrued expenses due to payment timing, partially offset by a $2.6 million increase in prepaid expenses, a $1.2 million increase in accounts receivable, and minor changes in inventory and lease liabilities.

Previous wording

During the three months ended December 31, 2024, we used $11.0 million of cash in operating activities resulting primarily from our net income of $17.4 million. This use of cash was partially offset by $35.2 million of non-cash items such as stock-based compensation, change in fair value of promissory notes, change in fair value of warrant liability, loss on equity method investment and depreciation and amortization expense. The net cash inflow of $6.9 million from changes in our operating assets and liabilities was primarily due to an increase in accounts payable and accrued expenses of $4.4 million primarily due to timing of payments and a decrease in prepaid expenses of $5.6 million associated with ONS-5010/LYTENAVA development costs relating to clinical trial and drug development costs, partially offset by an increase in inventory of $3.1 million relating to commercial inventory manufactured during the period.
