CORSICANA, Texas — December 23, 2025 — Leads & Copy — Birchtech Corp. has announced that its Board of Directors has approved a 1-for-5 reverse stock split of its common stock. The reverse split will take effect on December 26, 2025, and the company’s common stock is expected to begin trading on a split-adjusted basis at market open on December 31, 2025.
The company believes the reverse split will increase the price per share of its common stock, improve the marketability of its shares, position the company for future strategic and capital market opportunities, and support its planned uplisting strategy.
Birchtech Corp.’s trading symbol will remain unchanged; however, on the OTCQB, a “D” will be temporarily appended as the fifth character on the trading symbol for 20 business days starting on 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.
As a result of the reverse split, every five shares of issued and outstanding common stock will be combined into one share. The reverse split will not affect stockholders’ proportional ownership of the company, except to the extent that it results in a stockholder owning a fractional share.
No fractional shares will be issued; any fractional shares 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 that the reverse stock split is expected to elevate the company’s capital market profile, unlock access to the largest pool of institutional capital, broaden the company’s reach and enhance liquidity.
