Further to the news release dated Feb. 9, 2026, Bunker Hill Mining Corp. has released the effective date of its one-for-35 reverse stock split of the company's common stock, par value 0.0001 U.S. cent, and preferred stock, par value 0.0001 U.S. cent. The reverse stock split will be effective as of March 6, 2026, and the shares of common stock will commence trading, on a consolidated basis, on the TSX Venture Exchange at market opening on the consolidation date. Bunker Hill also wishes to announce, further to its news releases dated Feb. 9, 2026, and Feb. 13, 2026, certain amendments to its listed issuer financing exemption offering of up to 159,735,000 units of the company, inclusive of the agent's option (as defined herein), as further described below.

Reverse stock split

The company's name will be unchanged, and the common shares will continue to trade under the symbol BNKR on the TSX-V. Bunker Hill's new Cusip number after the reverse stock split will be 120613823, and the new ISIN will be US1206138232.

As of close of business on March 2, 2026, there were 1,407,494,573 common shares issued and outstanding. Immediately following the reverse stock split, a total of approximately 40,214,130 common shares are expected to be issued and outstanding, subject to adjustments for rounding. Assuming completion of the LIFE offering and the issuance of up to 159,735,000 LIFE units of the company on the closing date (as defined below), which assumes full exercise of the overallotment option by the agents, there are expected to be a total of approximately 44,777,988 common shares issued and outstanding on a postconsolidation basis, subject to adjustments for rounding. As of the date hereof, there are no shares of preferred stock outstanding, and, as such, there will be no shares of preferred stock outstanding following the LIFE offering and reverse stock split. No fractional shares will be issued as a result of the reverse stock split.

The reverse stock split was approved by a majority of the company's stockholders, by way of written consent, on Jan. 27, 2026. The reverse stock split remains subject to the approval of the TSX-V, and all figures referenced herein are therefore subject to change.
