Birchtech Corp Announces Reverse Stock Split to Support Planned Uplisting Strategy

CORSICANA, Texas, Dec. 23, 2025 (GLOBE NEWSWIRE) -- Birchtech Corp. (TSX: BCHT) (OTCQB: BCHT) (“Birchtech” or the “Company”), a leader in specialty activated carbon technologies for sustainable air and water treatment, today announced that its Board of Directors has approved a 1-for-5 reverse stock split of its common stock (the “Reverse Split”). The Reverse Split will be effective on December 26, 2025, with the Company’s common stock expected to begin trading on a split-adjusted basis at market open on December 31, 2025.

The Reverse Split is intended to increase the price per share of the Company’s common stock to support the Company’s efforts to improve the marketability of its shares, better position the Company for future strategic and capital market opportunities, and support the Company’s planned uplisting strategy.  

The Company’s trading symbol will remain unchanged, although on the OTCQB a “D” will be temporarily appended as the fifth character on the trading symbol for 20 business days starting the effective date of the Reverse Split.

Stockholders of the Company previously authorized the Board to effect a reverse stock split of the Company’s common stock, ranging from 1-for-2 to 1-for-5, with the exact ratio to be set by the Board, which has now been done.

As a result of the Reverse Split, every five (5) shares of issued and outstanding common stock will be combined into one (1) share. The Reverse Split will not affect stockholders’ proportional ownership of the Company, except to the extent that the Reverse Split results in a stockholder owning a fractional share. No fractional shares will be issued; any fractional resulting from the Reverse Split will be rounded up to the next whole share. The Reverse Split will not affect the Company’s number of authorized shares or the par value of the common stock. Proportional adjustments will be made to outstanding equity awards, warrants, options, and other securities in accordance with their terms. Transfer Online, Inc., the Company’s transfer agent, will act as exchange agent for the Reverse Split and will send instructions to stockholders of record regarding the process for exchanging share certificates. Shareholders holding shares in book-entry form, in brokerage accounts, or in “street name” are not required to take any action to reflect the Reverse Split.

Richard MacPherson, President & CEO of Birchtech Corp., said: “This reverse stock split is expected to elevate the Company’s capital market profile, which we believe will enable us to unlock access to the largest pool of institutional capital in the world, which we believe positions us to broaden our reach and enhance liquidity.”
