Forward looking statement

This presentation contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 including, without limitation, the potential therapeutic benefits of Ovid's current or future product candidates and pipeline programs; Ovid's expectations regarding the duration its cash runway, and the expectation that it will support the advancement of Ovid's pipeline; statements regarding the expected timing of the initiation, completion, and results and data of Ovid's clinical studies; the potential to add additional cohorts to the Phase 1 MAD study of OV329, expected timing of completion of the study and expected timing of data presentation; the expected timing of submission of a regulatory application for

a Phase 1 trial of OV350 IV and, the expected timing of initiation of the trial and expected timing of data presentation; Ovid's evaluation of the results of recently completed competitor trials to OV888/GV101 for CCM; the potential use and development of OV329, OV350 and other compounds from Ovid's library of direct activators of KCC2, and OV888/GV101 and other ROCK2 inhibitors; the potential therapeutic opportunity of OV329, OV350 and other compounds from Ovid's library of direct activators of KCC2, and OV888/GV101 and other ROCK2 inhibitors; the potential use of OV329 to treat neuronal hyperexcitability; the likelihood that data, including safety and tolerability data, for OV329 will support future development and therapeutic potential; the suitability of OV329 for a range indication opportunities; the clinical and regulatory development of KCC2 compounds in the Company's library including OV350, OV4071, OV4000 series and OV5000 series; the suitability of the Company's library of novel, direct KCC2 transporter activators for a range of formulations and administrations; the potential development and therapeutic opportunity of OV888/GV101; and the potential safety, selectivity and potency of OV888/GV101 and other ROCK2 inhibitors; and expectations regarding the size of the market for Ovid's current or future product candidates and pipeline programs. You can identify forward-looking statements because they contain words such as "will," "may," "plan," "believes," "intends," "anticipates," "design," "advance," "target," "seek," "expects," "demonstrates," and "potential," and similar expressions (as well as other words or expressions referencing future events, conditions or circumstances).

Forward-looking statements are based on Ovid's current expectations and assumptions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that may differ materially from those contemplated by the forward-looking statements, which are neither statements of historical factor guarantees or assurances of future performance. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, without limitation, uncertainties inherent in the preclinical and clinical development and regulatory approval processes, risks related to Ovid's ability to achieve its financial objectives, the risk that Ovid may not be able to realize the intended benefits of its technology or its business strategy, risks related to Ovid's ability to identify business development targets or strategic partners, to enter into strategic transactions on favorable terms, or to consummate and realize the benefits of any business development transactions and risks to Ovid's or any of its partners' abilities to meet anticipated deadlines and milestones. Additional risks that could cause actual results to differ materially from those in the forward-looking statements are set forth under the caption "Risk Factors" in Ovid's Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (SEC) on November 12, 2024, and in future filings Ovid makes with the SEC.
