Birchtech Corp., a leader in specialty activated carbon technologies for sustainable air and water treatment, reported financial results for the fourth quarter and full year ended December 31, 2025. The company successfully uplisted to the NYSE American in February 2026, raising $16.6 million and strengthening its balance sheet. Birchtech also announced the commercialization of its water treatment solutions business, receiving $0.9 million in purchase orders from a major mid-Atlantic utility.

Why it matters

Birchtech's uplisting and capital raise provide the company with the resources to accelerate growth in its air and water purification businesses. The commercialization of its water treatment solutions is a significant milestone, as the company looks to become a full-service provider of media, services, and lifecycle management for water utilities.

The details

In Q4 2025, Birchtech's product revenues grew 19.8% year-over-year, though total revenues declined due to a one-time $2.5 million licensing payment in the prior-year quarter. The company also obtained a $78 million final judgment in a patent infringement case and is pursuing collection. Birchtech introduced a new line of nuclear-grade ion exchange resins, SEA-IX, and announced successful demonstrations of its thermally rejuvenated activated carbon with municipal water utilities.

“The fourth quarter capped a year of execution across every dimension of our business. Our $78 million final judgment from the U.S. District Court of Delaware validated years of IP enforcement, and our February 2026 uplisting to the NYSE American, paired with a $16.6 million capital raise, gave us the balance sheet and market visibility to accelerate from here.”
