FOR IMMEDIATE RELEASE

FUEL TECH REPORTS 2024 FOURTH QUARTER AND FULL YEAR FINANCIAL RESULTS

WARRENVILLE, Ill., March 4, 2025 – 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 fourth quarter (Q4) and full year ended December 31, 2024.

“Revenues for full year 2024 came in at the lower end of our guidance range of $25 million to $26 million, due primarily to the impact of delayed project execution and to the timing of Air Pollution Control (APC) awards offset by a stronger performance at our FUEL CHEM® business segment,” said Vincent J. Arnone, President and CEO. “We continued our stewardship of selling, general and administrative expenses and ended the year in a strong financial position, with approximately $30 million in cash and investments, and no long-term debt.

“We believe that performance for the FUEL CHEM segment will improve in 2025, driven by a return to normalized chemical program utilization at our base accounts following extended plant outages at certain sites during the year, and incremental year-on-year contributions from a new commercial program on a coal-fired unit that commenced in the fourth quarter of 2024. We are pursuing an additional new FUEL CHEM account opportunity, starting with a demonstration of our TIFI® Targeted In-Furnace Injection™ technology that will likely commence in late third quarter of this year.”

Mr. Arnone continued, “While our overall results were negatively impacted by performance within the APC segment, we recently announced new awards of $1.6 million with an expectation to sign new contracts between now and early in the second quarter of 2025 with an aggregate value of between $4 million and $5 million. We are also pursuing separate opportunities with the operators of municipal waste combustion units who are being driven to meet lower emission requirements due to specific state regulatory requirements, as well as with entities associated with the development of data centers.

Data centers offer a promising opportunity for Fuel Tech’s emissions control solutions, including our SCR and ULTRA® technologies.”

Mr. Arnone concluded, “We are also continuing to pursue the growth and development of our Dissolved Gas Infusion (DGI®) technology. We will commence an extended demonstration at a fish hatchery in the Western U.S, our second at an aquaculture facility, early in the second quarter of 2025. We continue to receive inquiries regarding DGI from potential customers in multiple end markets and we are hopeful that we can generate our first commercial revenues in 2025. We are looking forward to showcasing DGI at Aquaculture 2025 being held in New Orleans March 6-10, 2025.”

RECONCILIATION OF GAAP NET LOSS TO EBITDA AND ADJUSTED EBITDA

(in thousands)

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, stock compensation expense, and intangible assets abandonment and building impairment. 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 loss has been included in the above financial table.
