Management Commentary

Richard MacPherson, Birchtech President and Chief Executive Officer, commented: "The first quarter of 2026 has created a launch pad for the achievements we expect to execute upon this year. With growth in our water business now making an impact on our bottom line with increased revenues, we will continue to see expansion in this area over the next several months.

"Across the rest of the business, we strengthened Birchtech on every front. We completed our uplisting to the NYSE American with a $16.4 million capital raise, broadening our investor base and fortifying our balance sheet. We formally initiated collection efforts on our approximately $78 million final patent infringement judgment. Returning to our position in the water market, we launched SEA-IX™, our nuclear-grade ion exchange resin line, capturing approximately $1 million in initial orders, and we expanded our water treatment solutions business with new supply orders from our existing mid-Atlantic utility customer, as well as new project awards.

"Subsequent to quarter-end, we further strengthened our leadership team with the appointment of Michael Mioska as Chief Financial Officer whose strategic financial leadership and oversight will contribute to our next phase of growth. With a reinforced balance sheet, a senior exchange listing, and two complementary business lines reinforcing each other, Birchtech is well positioned to deliver sustained growth and long-term value for shareholders" concluded MacPherson.

First Quarter 2026 Financial Results

Revenues increased 32% to $4.2 million in the first quarter, as compared to $3.2 million in the same year-ago quarter. The increase in revenues from the prior period was primarily due to growth in water treatment revenue along with increased revenue from our air business. This growth was partially offset by a decrease in licensing revenue as the Company had entered into a licensing agreement in the first quarter of 2025 with a one-time up-front license fee, for which there were no comparable revenues in the first quarter of 2026.

Gross profit totaled $1.4 million as compared to $1.2 million, in the same year-ago quarter. The increase in gross margin was primarily attributable to an increase in revenue partially offset by a decrease in high-margin licensing revenue.

SG&A expenses totaled $2.0 million in the first quarter of 2026, as compared to $2.2 million in the same year-ago quarter. The decrease in expenses was primarily due to lower legal fees.

R&D expenses totaled $0.6 million in the first quarter of 2026, as compared to $0.4 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 first quarter of 2026 totaled $1.3 million, or $0.06 per basic and diluted share, as compared to net loss of $1.7 million, or $0.09 per basic and diluted share, in the same year-ago quarter.

Adjusted EBITDA improved from a loss of ($1.2) million during the three months ended March 31, 2025, to a loss of ($1.0) million for the three months ended March 31, 2026.

Cash as of March 31, 2026, totaled $14.7 million, with no debt, as compared to $2.2 million as of December 31, 2025. The increase in cash reflects the $16.4 million capital raise completed in February 2026 concurrent with the Company's uplisting to the NYSE American, which significantly strengthened the Company's 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 three months ended March 31, 2026, and 2025, respectively:

	For the Three Months Ended
	March 31,			March 31,
	2026			2025
	(In thousands)

Net income (loss)	$	(1,346	)	$	(1,679	)

Non-GAAP adjustments:
Depreciation and amortization		106			72
Change in fair value of profit share		246			353
Income taxes		-			14
Stock based compensation		-			61

Adjusted EBITDA	$	(994	)	$	(1,179	)
