BCHT Birchtech Corp

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 a non-exclusive agreement with a second coal-fired power utility named as a defendant in the Company’s lawsuit filed in Arizona, which was previously announced on July 30, 2024. Due to confidentiality agreements and ongoing litigation, the specific terms of this agreement cannot be publicly disclosed.

Having now resolved all claims against the two group of defendants filed in the Arizona lawsuit, the remaining claims filed in Iowa and Missouri will continue against other defendants and have been consolidated and centralized in the Southern District of Iowa.

“This second agreement reinforces the industry’s strong acceptance of our patented technologies, while concurrently fortifying our balance sheet for the benefit of our shareholders,” said Richard MacPherson, CEO of Birchtech. “We are happy to have reached a positive business outcome with this utility, which has and will continue to benefit from our patented technologies for a number of years.

“Our outreach across the industry continues, including ongoing discussions with other defendants named in our recent lawsuits. We fully expect to enter license agreements and/or supply contracts with many of these utilities. The legal precedent established by the unanimous jury verdict of willful infringement issued in March 2024 in Federal Court has established a standard for acceptance of our position as it relates to our patented technologies. We look forward to engaging in positive business relationships with these power utilities as we seek to create sustainable, long-term value for our shareholders.”

Since filing an initial lawsuit in July 2019 against 43 defendants that included four major power utilities and numerous refined coal companies, Birchtech successfully obtained a pre-trial settlement with defendants AJ Gallagher, DTE, and a CERT Defendant in late 2023. Following the jury trial in the U.S. District Court of Delaware with the remaining CERT Defendants, the Company was awarded a $57 million jury award with a unanimous finding of willful infringement, along with inducing and contributory infringement. In July 2024, the Company filed three separate lawsuits against a total of 14 defendants, which were consolidated and centralized in the Southern District of Iowa in December 2024. In February 2025, the recently announced Evergy lawsuit was also transferred to the Southern District of Iowa.

Since 2019, the Company has reached 10 license and/or supply agreements with coal-fired utilities, including six coal-fired utilities previously named as defendants in the 2019 and 2024 lawsuit filings. Additional lawsuits remain outstanding as the Company seeks to protect its intellectual property on behalf of shareholders, and the Company awaits the final judgment to be issued from the March 2024 District Court of Delaware jury trial.
