Vancouver, British Columbia - Newsfile Corp. - September 23, 2025 - Cathedra Bitcoin Inc. (TSXV: CBIT) (OTCQB: CBTTF) (the "Company" or "Cathedra"), a bitcoin company that develops and operates digital infrastructure assets, today announced that its Board of Directors has approved a 30:1 consolidation of the Company's issued and outstanding subordinate voting shares and multiple voting shares (the "Consolidation").

The record date for the Consolidation is expected to be on or about October 14, 2025, and effective on or about October 15, 2025, subject to the approval of the TSX Venture Exchange. As a result of the Consolidation, every 30 subordinate voting shares and multiple voting shares of the Company issued and outstanding as of the record date would be consolidated into one subordinate voting share or multiple voting share, as applicable. No fractional subordinate voting shares would be issued; instead, any such fractional shares resulting from the Consolidation would be rounded down to the nearest whole share. The Consolidation would affect all shareholders uniformly and would not alter any shareholder's percentage interest in the Company's equity, except to the extent that the Consolidation results in any shareholder losing a fractional share due to rounding down.

The Company's subordinate voting shares would continue to trade on the TSX Venture Exchange under the symbol "CBIT" and on the OTCQB under the symbol "CBTTF," with the adjusted shares expected to begin trading on a post-Consolidation basis at the opening of trading on or after the effective date, under a new CUSIP number. Shareholders who do not hold their shares in physical form would not need to take any action, as the Consolidation would be processed automatically by the Company's transfer agent.

The Consolidation is intended to reduce the number of shares currently outstanding, streamlining the Company's capital structure.
