Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts and are often characterized by the use of words such as “believe,” “can,” “could,” “potential,” “plan,” “predict,” “goals,” “seek,” “should,” “may,” “may have,” “would,” “estimate,” “continue,” “anticipate,” “intend,” “expect” or by discussions of strategy, plans or intentions. Such forward-looking statements involve known and unknown risks, uncertainties, assumptions and other important factors that could cause our actual results, performance or achievements or industry results to differ materially from historical results or any future results, performance or achievements expressed, suggested or implied by such forward-looking statements. These include, but are not limited to, statements about the Company’s ability to develop, obtain regulatory approval for and commercialize its product candidates; the timing of future IND submissions, initiation of preclinical studies and clinical trials, and timing of expected clinical results for our product candidates; the Company’s success in early preclinical studies, which may not be indicative of results obtained in later studies or clinical trials; the outbreak of the novel strain of coronavirus disease, COVID- 19, which could adversely impact our business, including our preclinical studies and any future clinical trials; the potential benefits of our product candidates; the Company’s ability to obtain regulatory approval to commercialize our existing or any future product candidates; the Company’s ability to identify patients with the diseases treated by our product candidates, and to enroll patients in clinical trials; the success of our efforts to expand our pipeline of product candidates and develop marketable products through the use of our Magellan platform; the Company’s expectations regarding collaborations and other agreements with third parties and their potential benefits; the Company’s ability to obtain, maintain and protect our intellectual property; the Company’s reliance upon intellectual property licensed from third parties, including the license to use the Company’s Magellan platform; the Company’s ability to identify, recruit and retain key personnel; the Company’s financial performance; developments or projections relating to the Company’s competitors or industry; the impact of laws and regulations; the Company’s expectations regarding the time during which it will be an emerging growth company under the JOBS Act; and other factors and assumptions described in the Company’s public filings. These statements are based on the Company’s historical performance and on its current plans, estimates and projections in light of information currently available to the Company, and therefore, you should not place undue reliance on them. The inclusion of forward-looking information should not be regarded as a representation by the Company or any other personthat the future plans, estimates or expectations contemplated by us will be achieved. Forward-looking statements made in this presentation speak only asof the date of this presentation, and the Company undertakes no obligation to update them in light of new information or future events, except as required by law. You should carefully consider the above factors, as well as the factors discussed elsewhere in this presentation and our public filings, before deciding to invest in our common stock. The factors identified above should not be construed as an exhaustive list of factors that could affect the Company’s future results and should be read in conjunction with the other cautionary statements that are included in this presentation and our public filings. New risks and uncertainties arise from time to time, and it is impossible for the Company to predict those events or how they may affect the Company. If any of these trends, risks or uncertainties actually occurs or continues, the Company’s business, revenue and financial results could be harmed, the trading prices of its securities could decline, and you could lose all or part of your investment. All forward-looking statements attributable to the Company or persons actingon its behalf are expressly qualified in their entirety by this cautionary statement.

No representations or warranties are made by the Company or any of its affiliates as to the accuracy of any such statements or projections. Projections, assumptions and estimates of our future performance and the future performance of the industry in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described above.

The open-label extension will complete in September 2026. • Correlative biomarker analysis remains ongoing from the initial 90-day treatment duration with additional details to be presented at upcoming conferences including AD/PD 2026 in March 2026. Additional data including MDS-UPDRS updates from the open-label extension will also be presented at upcoming conferences. • A Phase 2 safety and efficacy trial is planned to initiate in early 2H26 that will further evaluate tolerability, biological evidence of substrate reduction, and clinical outcomes on MDS-UPDRS scores.
