CULLINAN METALS ANNOUNCES EFFECTIVE DATE FOR SHARE CONSOLIDATION

Further to the news release of Jan. 14, 2026, Cullinan Metals Corp. will complete a consolidation of the authorized and issued common shares of the company, effective at the opening of the markets on Wednesday, Feb. 4, 2026, on the basis of 10 existing common shares for one new share. No fractional common share will be issued upon the consolidation. Any fractional share resulting from the consolidation will be rounded down to the next whole common share, and no cash consideration will be paid in respect of fractional shares. Effective at the opening of markets on Feb. 4, 2026, the common shares will commence trading on the Canadian Securities Exchange on a postconsolidation basis under the existing ticker CMT. The new ISIN is 23003L201, and the Cusip is CA23003L2012. The record date is Feb. 5, 2026.

The company's board of directors believes that the share consolidation will provide the company with greater flexibility for the continued development of its business and the growth of the company, including financing arrangements.

The company would like to clarify that registered shareholders whose holdings are represented by a physical share certificate will be sent a letter of transmittal from Odyssey Trust Company, transfer agent to the company, with information related to the exchange of the physical certificate for a direct registry system statement or new physical share certificate representing the postconsolidation holdings of the shareholder. Intermediaries, such as brokerage houses and financial institutions, which may hold physical certificates on behalf of a beneficial shareholder, will facilitate the transmittal of the common shares in those instances; however, beneficial positions held through CDS and DTC will be automatically exchanged on completion of the consolidation and subsequent to the effective date. Registered shareholders whose holdings are represented by a DRS statement will receive a new, postconsolidation DRS statement showing the adjustment to their position.

The board of directors believes that the proposed consolidation will better position the company to raise the funds it requires to continue financing its business activities.
