BIRCHTECH ANNOUNCES ANTICIPATED UPLIST TO NYSE AMERICAN STOCK EXCHANGE WITH CONCURRENT OFFERING

Birchtech Corp. expects its shares of common stock to be approved for listing on NYSE American LLC. The company anticipates that its common stock will begin trading on the NYSE American under the symbol BCHT at the opening of trading on or about Feb. 12, 2026, subject to final authorization by the NYSE American of the company's listing application and continued compliance with the exchange rules.

In connection with the anticipated NYSE American listing, the company is also conducting a concurrent offering of its common stock, subject to market conditions and regulatory approval. The approval of the listing of the common stock on the NYSE American is a condition to the completion of the offering. Additional details regarding the offering will be provided through the company's filings with the U.S. Securities and Exchange Commission (SEC).

The company's common stock is presently traded on the Toronto Stock Exchange under the symbol BCHT and is quoted on the OTCQB market tier operated by OTC Markets Group Inc. under the symbol BCHT. The company expects that its shares of common stock will continue to trade on the OTCQB until the close of the market on or about the day before the common stock begins trading on the NYSE American. Upon effectiveness of the listing on the NYSE American, trading of the common stock on the OTCQB will terminate. Stockholders of the company do not need to take any action prior to the listing of the company's shares on the NYSE American. The company will remain listed on the TSX.

"The anticipated uplisting to the NYSE American will mark a significant milestone for Birchtech as we continue to focus on driving sustainable growth, converting additional utilities into long-term licensees and supply customers, and accelerating the rollout of our next-generation platform in water," said Richard MacPherson, chief executive officer of Birchtech. "Being listed on the NYSE American is expected to increase corporate visibility, enhance liquidity, and raise institutional and retail investor awareness for our company in the capital markets."
