On June 5, 2023, Mind Medicine (MindMed) Inc. (the “Company”) issued a press release relating to the Company’s 2023 Annual General Meeting of Shareholders.

Leading Proxy Advisory Firm ISS Recommends MindMed Shareholders Vote FOR All Six Company Nominees

ISS Believes Company’s Director Nominees Represent an “Unusually Strong” Group of Current and Former Executives From Relevant Fields and Are Best Suited to Continue Overseeing MindMed’s Strategy

Concludes There is “No Reasonable Basis” to Question MindMed’s Drug Development Strategy or Third-Party Support From Greenleaf Health

Confirms FCM Has Not Made a Compelling Case for Change; ISS Does Not Recommend Any of Dissident’s Nominees

MindMed Encourages Shareholders to Follow ISS Recommendation and Vote on the WHITE Universal Proxy Card FOR ALL SIX of the Company’s Director Nominees

NEW YORK – June 5, 2023 – Mind Medicine (MindMed) Inc. (NASDAQ: MNMD) (NEO: MMED), (the “Company” or “MindMed”) today announced that leading proxy advisory firm Institutional Shareholder Services Inc. (“ISS”) has recommended shareholders vote for ALL of MindMed’s six highly qualified director nominees at the upcoming Annual Meeting of Shareholders (“Annual Meeting”), scheduled for June 15, 2023.

•

“The company's regulatory strategy appears reasonable and has received third-party validation, and the drop in the company's share price after its September 2022 equity raise is in line with sectoral trends.”

•

“The board has also undergone a complete refresh of its ranks, yielding a strong cohort of independent directors, all with industry experience. Against this backdrop, the dissident has not made the case for change at MindMed.”

•

“As the dissident has not presented a convincing case for change at the company, support for all management nominees is warranted.”

ISS highlights the Company’s Board refreshment, the relevant experience of MindMed’s candidates and the Board’s positive corporate governance:

•

“The board's full refreshment of all six members began on Sept. 29, 2021, with the appointment of Vallone and Krebs, and the company expects to complete the refreshment at this year's AGM with the election of its new nominee, Gryska.”

•

“In this process, the board has been able to attract an unusually strong collection of former and current executives in the fields of mental health (Vallone), drug development and commercialization (Bruhn, Crystal, and Krebs), and financial management (Gryska).”

•

“The board utilizes many conventional governance best practices, such as an independent chair, annual director elections, a well-refreshed board, and a majority voting standard for director elections with a director resignation policy.”

•

“To its credit, the board appears to have ensured that the company has sufficient cash for the next two years of the company's development. The company's cash runway over the past three quarters, following the company's Q3 2022 financings, appears to be appreciably greater than its peer median.”

•

“The board took the additional step of seeking outside validation of its (regulatory) strategy by engaging Greenleaf Health, which has supported the company's choice.”

•

“There appears to be no clear reason to question Greenleaf's concurrence with the company's regulatory strategy, even given the provider-client relationship between these parties. The company's collaborator at University Hospital Basel, Matthias Liechti, also supports the company's choice of this Phase IIb trial.”

•

“The company's trial strategy appears to be based on reasonable strategic considerations, and there seems to be no board dysfunction that is adversely affecting its oversight of the company's strategy.”

•

“At this stage in the company's development, there appears to be no reasonable basis for shareholders to question either the company's development strategy or Greenleaf's third-party validation.”

Robert Barrow, Chief Executive Officer and Director of MindMed, stated: “We appreciate ISS’s support for all six of MindMed’s director nominees and believe ISS rightly acknowledges the significant progress we have made in evolving MindMed over the past two years. We are successfully executing our plan to reach key data milestones and create value – and ISS’s recommendation is validation of our people and approach in that endeavor. Each of our nominees brings proven experience in the key areas of focus for MindMed and reflects a Board that has been proactively and thoughtfully refreshed in recent years. This is a critical period for the Company, and we are committed to maintaining our forward progress to deliver on our mission for patients and shareholders.”

MindMed believes ISS's respected standing as both an expert in contested situations and as an objective third-party should reinforce to shareholders that the strategy presented by the MindMed Board and management is the right one. MindMed encourages all shareholders to follow the recommendation of ISS and vote "FOR" the Company's six highly qualified director nominees using the WHITE universal proxy card at the upcoming Annual Meeting, scheduled for June 15, 2023.

Due to new U.S. federal rules requiring us to list FCM’s nominees in addition to the Board’s nominees, your WHITE proxy card this year has more names on it than the six directors to be elected. The inclusion of FCM’s nominees on our WHITE proxy card does NOT mean the Board endorses them.

Vote TODAY on the WHITE proxy card FOR all six of the Board’s nominees, WITHHOLD on FCM’s nominees and FOR the other proposals recommended by your Board.

You can help reject FCM’s efforts to take control of the Board by discarding any blue proxy cards and materials you may receive from FCM.

Shareholders will receive proxy materials directly via the preferred method, hard copy or email, specific to each shareholder’s account. If you have any questions, or need assistance voting your shares, please contact the firm assisting us in the solicitation of proxies:
