CORSICANA, Texas, March 31, 2026 (GLOBE NEWSWIRE) -- Birchtech Corp. (NYSE:BCHT) (TSX:BCHT) ("Birchtech" or the "Company"), a leader in specialty activated carbon technologies for sustainable air and water treatment, today reported financial results for the fourth quarter and full year ended December 31, 2025.

Key Fourth Quarter 2025 & Subsequent Operational Highlights

Successfully uplisted to the NYSE American in February 2026 with a concurrent public offering raising aggregate gross proceeds of approximately $16.6 million, including the partial exercise of the underwriters' over-allotment option, significantly strengthening the Company's balance sheet and expanding its investor base.
Obtained final judgment of approximately $78 million from the U.S. District Court for the District of Delaware in patent infringement case, increased from the original $57 million unanimous jury verdict. Although defendants have filed an appeal, the Company has initiated the collection process and is pursuing enforcement options.
Introduced SEA-IX™, a new line of nuclear-grade ion exchange resins, for the capture of harmful contaminants in potable and industrial wastewater, including power and nuclear utilities. With this new product, the Company's full-service water treatment solutions now includes multiple media appropriate for the removal of numerous contaminants, as well as changeout services and equipment.
Announced the commercialization of the Company's water treatment solutions business after having received purchase orders collectively totaling approximately $0.9 million with a large mid-Atlantic power utility for filtration system media replacement services for the removal of contaminants from wastewater at two locations.
Announced successful demonstrations conducted with regulated municipal water utilities that showed the Company's thermally rejuvnenated GAC performed comparably to virgin carbon in removing PFAS.
Announced collaboration with national engineering firm Civil & Environmental Consultants (CEC) to offer RSSCT testing for its large base of hundreds of water-utility clients nationwide, providing an incremental business development pathway for the Company's water business.
Exhibited at key industry and investor conferences including the WaterPro Conference, WEF Technical Exhibition & Conference, the Noble Emerging Growth Conference and the iAcess Alpha Virtual Best Ideas Spring Investment Summit.

Management Commentary

Richard MacPherson, Birchtech Chief Executive Officer, commented: "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. On the commercial side, our air division saw 20% growth in product revenues in the fourth quarter, remaining a stable, high-margin revenue driver.

"Our water platform also gained meaningful traction during the year. We secured approximately $0.9 million in initial purchase orders from a major mid-Atlantic utility, established a relationship with CEC to bring RSSCT testing to their nationwide client base, and validated our Carbon Rejuvenation™ process with results on par with virgin activated carbon. Along with the recent launch of our SEA-IX™ nuclear-grade ion exchange resin line, each of these progressions moves Birchtech closer to becoming a full-service water purification provider spanning media, services, and lifecycle management.

"The priorities ahead are clear: collect on our $78 million judgment, grow the roster of licensed utilities purchasing our activated carbon, continue expanding our water treatment solutions for smaller water utilities, and scale Carbon Rejuvenation™ toward the construction of our first facility. With a fortified balance sheet, an NYSE American listing driving broader investor access, and two business lines building on each other, we are positioned to deliver sustained growth and long-term value for shareholders," concluded MacPherson.

Fourth Quarter 2025 Financial Results

Revenues totaled $3.8 million in the fourth quarter, as compared to $5.6 million in the same year-ago quarter. Product revenues increased 19.8% to $3.6 million, as compared to $3.0 million in the same year-ago quarter. The change in revenues was primarily due to a one-time $2.5 million licensing payment from a large Southwest utility.

Gross profit totaled $1.2 million, or 31% of total revenues, in the fourth quarter of 2025, as compared to $3.3 million, or 60% of total revenues, in the same year-ago quarter. The change in gross profit was a result of the one time license fee recognized in Q4 2024. This change was partially offset by an increase in product revenue during the fourth quarter of 2025 compared to the fourth quarter of 2024. The decrease in gross profit as a percentange of revenues was a result of the one time license revenue generated in the fourth quarter of 2024 having higher margin.

SG&A expenses decreased 42% to $2.0 million in the fourth quarter of 2025, as compared to $3.4 million in the same year-ago quarter. The decrease in expenses was primarily due to lower legal fees in connection with patent litigation.

R&D expenses totaled $0.5 million in the fourth quarter of 2025, as compared to $0.0 million in the same year-ago quarter. R&D expenses relate to research conducted to develop water treatment products utilizing new sorbent technologies.

Net loss for the fourth quarter of 2025 totaled $0.6 million, or $0.03 per basic and diluted share, as compared to $1.3 million or $0.07 per basic and diluted share.

Adjusted EBITDA, a non-GAAP measure, totaled ($1.1) million in the fourth quarter of 2025, compared to ($0.5) million for the fourth quarter of 2024.

Cash as of December 31, 2025 totaled $2.2 million, with no debt, as compared to $3.5 million, with no debt, as of December 31, 2024. Subsequent to the quarter end, the Company completed a $16.6 million capital raise concurrent with its uplisting to the NYSE American in February 2026, significantly strengthening its balance sheet.

Non-GAAP Financial Measures

To supplement our consolidated financial statements presented in accordance with GAAP and to provide investors with additional information regarding our financial results, we consider and are including herein Adjusted EBITDA, a Non-GAAP financial measure. We view Adjusted EBITDA as an operating performance measure and, as such, we believe that the GAAP financial measure most directly comparable to it is net income (loss). We define Adjusted EBITDA as net income adjusted for interest and financing fees, income taxes, depreciation, amortization, stock-based compensation, and other non-cash income and expenses. We believe that Adjusted EBITDA provides us an important measure of operating performance because it allows management, investors, debtholders and others to evaluate and compare ongoing operating results from period to period by removing the impact of our asset base, any asset disposals or impairments, stock based compensation and other non-cash income and expense items associated with our reliance on issuing equity-linked debt securities to fund our working capital.

Our use of Adjusted EBITDA has limitations as an analytical tool, and this measure should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP, as the excluded items may have significant effects on our operating results and financial condition. Additionally, our measure of Adjusted EBITDA may differ from other companies' measure of Adjusted EBITDA. When evaluating our performance, Adjusted EBITDA should be considered with other financial performance measures, including various cash flow metrics, net income and other GAAP results. In the future, we may disclose different non-GAAP financial measures in order to help our investors and others more meaningfully evaluate and compare our future results of operations to our previously reported results of operations.

The following table shows our reconciliation of net income (loss) to adjusted EBITDA for the fourth quarters and twelve months ended December 31, 2025 and 2024, respectively:

	For the Three Months Ended						For the Twelve Months Ended
	December 31,			December 31,			December 31,			December 31,
	2025			2024			2025			2024
	(In thousands)						(In thousands)

Net income (loss)	$	(593	)	$	(1,613	)	$	(3,026	)	$	(10,802	)
