This presentation contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements concerning data from and future enrollment for our clinical trials and our pipeline of additional indications. These forward-looking statements relate to us, our business prospects and our results of operations and are subject to certain risks and uncertainties posed by many factors and events that could cause our actual business, prospects and results of operations to differ materially from those anticipated by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those described under the heading “Risk Factors” included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and our Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2025 and June 30, 2025 and in our other filings with the U.S. Securities and Exchange Commission (the “SEC”). Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this presentation. In some cases, you can identify forward-looking statements by the following words: “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “aim,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would” or the negative of these terms or other comparable terminology, although not all forward-looking statements contain these words. We undertake no obligation to revise any forward-looking statements in order to reflect events or circumstances that might subsequently arise. These forward-looking statements are based upon our current expectations and involve assumptions that may never materialize or may prove to be incorrect. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of various risks and uncertainties, including, without limitation: our clinical data related to gene therapies for the treatment of inherited retinal diseases is preliminary and related to a relatively small group of patients, and, as a result, data that initially appears promising may be revised, updated, or invalidated at a later data readout and/or may ultimately not be capable of duplication in additional patients; failure to successfully integrate our businesses following our acquisition of former Opus Genetics Inc. (the “Opus Acquisition”) could have a material adverse effect on our business, financial condition and results of operations; the Opus Acquisition significantly expanded our product pipeline and business operations and shifted our business strategies, which may not improve the value of our common stock; our gene therapy product candidates are based on a novel technology that is difficult to develop and manufacture, which may result in delays and difficulties in obtaining regulatory approval; our planned clinical trials may face substantial delays, result in failure, or provide inconclusive or adverse results that may not satisfy FDA requirements to further develop our therapeutic products; delays or difficulties associated with patient enrollment in clinical trials may affect our ability to conduct and complete those clinical trials and obtain necessary regulatory approvals; changes in regulatory requirements could result in increased costs or delays in development timelines; we depend heavily on the success of our product pipeline; if we fail to find strategic partners or fail to adequately develop or commercialize our pipeline products, our business will be materially harmed; others may discover, develop, or commercialize products similar to those in our pipeline before or more successfully than we do or develop generic variants of our products even while our product patents remain active, thereby reducing our market share and potential revenue from product sales; we do not currently have any sales or marketing infrastructure in place and we have limited drug research and discovery capabilities; the future commercial success of our products could significantly depend upon several uncertain factors, including third-party reimbursement practices and the existence of competitors with similar products; product liability lawsuits against us or our suppliers or manufacturers could cause us to incur substantial liabilities and could limit commercialization of any product candidate that we may develop; failure to comply with health and safety laws and regulations could lead to material fines; we have not generated significant revenue from sales of any products and expect to incur losses for the foreseeable future; our future viability is difficult to assess due to our short operating history and our future need for substantial additional capital, access to which could be limited by any adverse developments that affect the financial services markets; raising additional capital may cause our stockholders to be diluted, among other adverse effects; we operate in a highly regulated industry and face many challenges adapting to sudden changes in legislative reform or the regulatory environment, which affects our pipeline stability and could impair our ability to compete in international markets; we may not receive regulatory approval to market our developed product candidates within or outside of the U.S.; with respect to any of our product candidates that receive marketing approval, we may be subject to substantial penalties if we fail to comply with applicable regulatory requirements; our potential relationships with healthcare providers and third-party payors will be subject to certain healthcare laws and regulations, which could expose us to extensive potential liabilities; we rely on third parties for material aspects of our business, such as conducting our nonclinical and clinical trials and supplying and manufacturing bulk drug substances, which exposes us to certain risks; we may be unsuccessful in entering into or maintaining licensing arrangements (such as our license agreement with Viatris, Inc.) or establishing strategic alliances on favorable terms, which could harm our business; our current focus on the cash-pay utilization for future sales of RYZUMVI may limit our ability to increase sales or achieve profitability with this product; inadequate patent protection for our product candidates may result in our competitors developing similar or identical products or technology, which would adversely affect our ability to successfully commercialize; we may be unable to obtain full protection for our intellectual property rights under U.S. or foreign laws; we may become involved in lawsuits for a variety of reasons associated with our intellectual property rights, including alleged infringement suits initiated by third parties; we are dependent on our key personnel, and if we are not successful in attracting and retaining highly qualified personnel, we may not be able to successfully implement our business strategy; as we grow, we may not be able to operate internationally or adequately develop and expand our sales, marketing, distribution, and other corporate functions, which could disrupt our operations; the market price of our common stock is expected to be volatile; our common stock may be subject to delisting from the Nasdaq Capital Market, which could adversely affect our ability to access capital markets; factors out of our control related to our securities, such as securities litigation or actions of activist stockholders, could adversely affect our business and stock price and cause us to incur significant expenses; and our business could experience an adverse impact from current or proposed tariffs on imported goods we purchase. The foregoing review of important factors that could cause actual events to differ from expectations should not be construed as exhaustive. Readers are urged to carefully review and consider the various disclosures made by us in this report and in our other reports filed with the SEC that advise interested parties of the risks and factors that may affect our business. All forward-looking statements contained in this presentation speak only as of the date on which they were made. We undertake no obligation to update such statements to reflect events that occur or circumstances that exist after the date on which they were made. Disclosures and Forward-Looking Statements 2

OPGx-LCA5: Designed to Restore Structure and Function in Photoreceptors 10 Lebercilin is a ciliary protein critical for the function of photoreceptor inner and outer segments1 In LCA5 patients, photoreceptor function is severely impaired due to a lack of functioning lebercilin1 − However, photoreceptors can survive through the third decade of life, suggestive of a broad window for therapeutic intervention2 • OPGx-LCA5 is designed to address mutations in the LCA5 gene, which encodes for the lebercilin protein − Clinically derisked AAV8 vector delivers a functional LCA5 gene directly to photoreceptor cells − Same promoter technology as Luxturna − Validated surgical delivery method via subretinal injection AAV, adeno-associated virus; LCA5, Leber congenital amaurosis 5. 1.

29 Powerful Participant-Reported Outcomes After OPGx-LCA5 Treatment A d u l t P a r t i c i p a n t s 01-01: Reported being able to identify her children within a larger group of children 1 month after surgery which she previously could not have done. 01-03: Had no formative vision prior to treatment. Reported being able to see his newborn niece for the first time and watch his sister get married. Described his newfound independence, including his ability to pour a glass of wine and drink it unassisted for the first time in his life. Has been able to travel independently and, as a result, he acquired a new job, which requires a greater level of independence than he previously had. 01-04: Reported that since treatment, she no longer requires a cane and can now navigate urban environments independently. P e d i a t r i c P a r t i c i p a n t s 01-05: Reported being able to walk and cook without the assistance of others, and how treatment has helped her in her writing capabilities. Her mother described how her daughter’s eyes moved and rotated independently of one another prior to surgery, but that now they seem to be more coordinated in their movements. 01-06: Reported a noticeable difference in the visual brightness between his treated and untreated eyes. 01-07: Mostly nonvisual prior to treatment. Reported taking a visit to a local zoo, where she was able to visualize an owl for the first time.
