WARRENVILLE, Ill., Aug. 04, 2026 (GLOBE NEWSWIRE) -- Fuel Tech, Inc. (NASDAQ:FTEK), a technology company using advanced engineering processes to provide emissions control systems and water treatment technologies in utility and industrial applications, today reported financial results for the second quarter ended June 30, 2026 ("Q2 2026").

"Revenues for Q2 2026 rose 17% and reflected strong performance from our FUEL CHEM^® and Air Pollution Control ("APC") business segments," said Vincent J. Arnone, President and CEO. "We are pleased with our performance at the midpoint of the year and remain optimistic about the outlook for each of our business segments for full year 2026. We are preparing for what has historically been a strong third quarter for FUEL CHEM and continue to expect that segment revenues will approximate last year’s results. For APC, including our recently announced contract awards of $3 million, our effective backlog is approximately $17 million, which is more than double the backlog at the end of 2025. In addition, we have commenced engineering work on our recently announced large contract at a publicly-owned Midwest utility. Our business development activities across FUEL CHEM, APC and our DGI^® Dissolved Gas Infusion water treatment division are encouraging. As of June 30, 2026, our balance sheet included cash, cash equivalents, and investments of approximately $30 million and no long-term debt."

Mr. Arnone concluded, "As announced today, Ramesh Nuggihalli will be succeeding me as President and CEO of Fuel Tech effective August 10, 2026. In getting to know Ramesh during this process, I am confident that his background, temperament, and accomplishments make him exceptionally well positioned to lead Fuel Tech into its next chapter of growth and development. Serving Fuel Tech has been one of the greatest honors of my career, and I am proud of what we have achieved. I look forward to supporting Ramesh and the entire Fuel Tech organization as a member of the Board of Directors."

Business Segment Performance

All comparisons are to the second quarter ended June 30, 2025 unless otherwise stated.

Revenues generated by the APC segment rose by 11% to $2.8 million in Q2 2026, primarily attributable to the timing of project execution on existing contracts and increased consolidated segment backlog resulting from new project awards. Segment gross margin declined to 36% compared to 44%, due to product and project mix.

Consolidated APC segment backlog at June 30, 2026 was $14.3 million compared to $7.0 million at December 31, 2025. Backlog at June 30, 2026 included the recently awarded APC contracts valued at $10 million associated primarily with a utility grid enhancement project in the Midwest.

FUEL CHEM segment revenue rose 21% to $3.7 million from $3.1 million, primarily due to increased operational dispatch at legacy accounts. Segment gross margin declined to 45% from 47%, the result of demonstration costs, increased freight costs and additional internal labor costs for unit maintenance.

Second Quarter 2026 ("Q2 2026") Consolidated Results Overview

All comparisons are to the second quarter ended June 30, 2025 unless otherwise stated.

Consolidated revenues for Q2 2026 rose 17% to $6.5 million from $5.6 million, driven by increases in both APC and FUEL CHEM segment revenues.

Consolidated gross margin for Q2 2026 declined to 41% of revenues from 46% of revenues, driven by declines in both APC and FUEL CHEM segment gross margins.

SG&A expenses for Q2 2026 were $3.6 million, or 55.4% of revenues, compared to $3.3 million, or 60.2% of revenues, reflecting higher revenues compared to the prior year period.

Interest income for Q2 2026 was $266,000 compared to $537,000. Income generated is primarily related to interest received on the held-to-maturity debt securities and money market funds. The decrease is related primarily to a one-time, $257,000 collection of the Employee Retention Credit ("ERC") benefit under the CARES Act in last year’s second quarter.

Net loss in Q2 2026 was $(1.2) million, or $(0.04) per share, compared to net loss of $(0.7) million, or $(0.02) per share.

Adjusted EBITDA loss was $(1.2) million in Q2 2026 compared to an Adjusted EBITDA loss of $(0.9) million.

Financial Condition

As of June 30, 2026, cash and cash equivalents were $7.6 million, short-term investments were $12.0 million, and long-term investments totaled $10.0 million. Stockholders’ equity as of June 30, 2026 was $37.4 million, or $1.20 per share, and the Company had no debt.

Adjusted EBITDA

To supplement the Company's consolidated financial statements presented in accordance with generally accepted accounting principles in the United States (GAAP), the Company has provided an Adjusted EBITDA disclosure as a measure of financial performance. Adjusted EBITDA is defined as net income (loss) before interest expense, income tax expense (benefit), depreciation expense, amortization expense, and stock compensation expense. The Company's reference to these non-GAAP measures should be considered in addition to results prepared in accordance with GAAP standards, but are not a substitute for, or superior to, GAAP results.

Adjusted EBITDA is provided to enhance investors' overall understanding of the Company's current financial performance and ability to generate cash flow, which we believe is a meaningful measure for our investor and analyst communities. In many cases non-GAAP financial measures are utilized by these individuals to evaluate Company performance and ultimately determine a reasonable valuation for our common stock. A reconciliation of Adjusted EBITDA to the nearest GAAP measure of net income (loss) has been included in the above financial table.
