Forward Looking Statements

This communication 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 about future financial and operating results, our plans, objectives, expectations, and intentions with respect to future operations, products and services; and other statements identified by words such as "will likely result," "are expected to," "will continue," "is anticipated," "estimated," "believe," "intend," "plan," "projection," "outlook" or words of similar meaning.

Forward-looking statements in this communication include, without limitation, statements regarding the expected benefits of the expansion of the Company's clinical site network from three to five sites in Australia, including the anticipated impact on patient recruitment, enrollment timelines, geographic reach, and operational efficiency; the continued progress, timing, and execution of the Company's ongoing Phase IIb clinical trial evaluating natural psilocybin for the treatment of Adjustment Disorder in patients with cancer in a palliative care setting; the ability of newly added site partners, including Ramsay Health Care and NeuroCentrix, to support clinical trial activities; the Company's ability to supply GMP-compliant psilocybin product (NPX-5) for use in the trial; and the potential for the trial to generate meaningful clinical data. These statements are based on current assumptions and expectations, including assumptions that the addition of new clinical sites will improve recruitment and enrollment rates, that patient dosing and enrollment will continue as anticipated, that the Company will maintain sufficient product supply and manufacturing capabilities, that site partners will perform as expected, and that the Company will obtain and maintain all necessary regulatory and other approvals required to conduct the trial. These assumptions may prove incorrect. There are numerous risks and uncertainties that may cause actual results or performance to differ materially from those expressed or implied by these forward-looking statements, including risks related to delays in site activation, patient recruitment or enrollment, variability in clinical trial outcomes, supply chain or manufacturing disruptions, and the Company's ability to execute its clinical development strategy.

These risks and uncertainties include, among others: (i) the Company's ability to maintain compliance with Nasdaq's continued listing standards; (ii) potential volatility in the Company's share price; (iii) changes in the regulatory, competitive, and economic landscape; and (iv) risks associated with the Company's development plans and clinical trials. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the "Risk Factors" section of the Company's final prospectus (File No. 333-298285) filed with the Securities and Exchange Commission (the "SEC") on November 3, 2025 and other documents filed by Psyence BioMed from time to time with the SEC.

These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Actual results and future events could differ materially from those anticipated in such statements. Nothing in this communication should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. Except as required by law, Psyence BioMed does not intend to update these forward-looking statements.
