Item 2.02 Results of Operations and Financial Condition.
On January 12, 2026, Definium Therapeutics, Inc., formerly known as Mind Medicine (MindMed) Inc. (the “Company”), posted an updated corporate presentation on its website (the “Presentation”). The Presentation discloses the Company’s estimated preliminary financial information of cash, cash equivalents and investments of approximately $412 million as of December 31, 2025.
This estimate of cash, cash equivalents and investments is preliminary and subject to completion. As a result, this unaudited preliminary financial information reflects the Company’s preliminary estimate with respect to such information, based on information currently available to the Company’s management, and may vary from the Company’s actual financial position as of December 31, 2025. The unaudited preliminary cash, cash equivalents and investments included in the Presentation and this Current Report on Form 8-K have been prepared by, and are the responsibility of, the Company’s management. The Company’s independent registered public accounting firm, KPMG LLP, has not audited, reviewed, compiled or completed its procedures with respect to such unaudited financial information and, accordingly, KPMG LLP does not express an opinion or any other form of assurance with respect thereto.
Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.
On January 9, 2026, the Company filed a Notice of Alteration with the Province of British Columbia Registrar of Companies to alter its Notice of Articles to change the Company’s corporate name from “Mind Medicine (MindMed) Inc.” to “Definium Therapeutics, Inc.” (the ”Amendment”). The Amendment was approved by the Company’s Board of Directors on January 9, 2026. A copy of the Notice of Articles is attached as Exhibit 3.1 and the Certificate of Change of Name is attached as Exhibit 3.2 hereto and are incorporated by reference herein.
The rebranding reflects the Company’s transition into its next phase of development, positioning the Company as a leader in psychiatric drug development. No action is required from the Company’s shareholders. The CUSIP number for the Company’s Common Shares, no par value per share (the “Common Shares”), remains unchanged. The Common Shares will continue to trade on the Nasdaq Stock Market under the new ticker symbol “DFTX” as of market open on January 13, 2026.
