Rhea-AI Filing Summary

Fuel Tech reported higher revenue and margins in 2025 but remained unprofitable. Fourth-quarter 2025 revenue rose 37% to $7.2 million, lifting gross margin to 44.6% from 42.3%, while the net loss narrowed to $0.04 per share from $0.06.

For full-year 2025, revenue increased to $26.7 million from $25.1 million, with gross margin improving to 46.4% from 42.3%. FUEL CHEM segment revenue grew 27.9% for the year, reaching its highest level since 2018, helped by stronger coal unit utilization and a new U.S. demonstration program.

APC segment revenue declined for the year but rose 36.7% in the fourth quarter, and segment backlog increased to $7.0 million from $6.2 million. The company highlighted a data-center-related APC sales pipeline of approximately $75–$100 million and ongoing DGI water treatment demonstrations. Fuel Tech ended 2025 with $11.9 million in cash, $19.9 million in investments, stockholders’ equity of $39.9 million, and no debt.

Insights

Revenue and margins improved in 2025, but losses and weak APC trends kept results mixed.

Fuel Tech delivered solid top-line growth and better profitability metrics. Q4 2025 revenue grew to $7.2M, with gross margin at 44.6%, and full-year revenue reached $26.7M as gross margin rose to 46.4%, signaling more profitable project mix and stronger FUEL CHEM performance.

Despite this, the business still posted a net loss of $0.08 per share for 2025 and a larger Adjusted EBITDA loss of $2.7M compared with 2024. APC segment revenue declined for the year, even though Q4 rebounded and backlog increased to $7.0M, pointing to uneven demand and project timing.

The balance sheet remains a stabilizing factor, with $11.9M in cash, $19.9M in investments, stockholders’ equity of $39.9M, and no debt as of December 31, 2025. Execution on the $75–$100M APC pipeline tied to data centers and successful conversion of DGI demonstrations over 2026 will be key to whether revenue growth can translate into sustained profitability in future periods.

FOR IMMEDIATE RELEASE

 

FUEL TECH REPORTS 2025 FOURTH QUARTER AND FULL YEAR FINANCIAL RESULTS

 

WARRENVILLE, Ill., - March 3, 2026 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 and full year ended December 31, 2025.

 

“2025 was a year of achievement for Fuel Tech, highlighted by a resurgence at our FUEL CHEM® operations that produced the highest annual segment revenue since 2018, a broadened opportunity landscape at our Air Pollution Control (“APC”) business segment driven in large part by the expected growth of power generation to support data center construction and operation, and measurable progress at our Dissolved Gas Infusion (“DGI”) business segment,” said Vincent J. Arnone, President and CEO. “We maintained a strong balance sheet, finishing the year with nearly $32 million in cash and investments and no long-term debt.”

 

Business Segment Performance

Revenues at FUEL CHEM increased by 37.4% in the fourth quarter of 2025 (“Q4 2025”) and by 27.9% for the 2025 full year (“FY 2025”) compared to their respective prior year periods, with gross margin being maintained at historic segment levels. Results for Q4 2025 included contributions from a six-month, commercially-priced demonstration program for a new FUEL CHEM customer in the United States that commenced in early November and is continuing in the current first quarter. The annual revenue potential from this commercial contract should it convert from a demonstration is expected to be approximately $2.5 to $3.0 million based on the customer running the program full-time, with the revenue expected to generate historic FUEL CHEM gross margins.

 

 

 

Revenues generated by the Air Pollution Control (“APC”) segment rose by 36.7% in Q4 2025 compared to the same period last year, but declined for FY 2025. Revenues for both periods reflected customer-driven delays and timing of project completion. The Company announced $8.8 million of new APC awards in 2025 from new and existing customers in the U.S., Europe and Southeast Asia. This activity supported an increase in consolidated APC segment backlog at December 31, 2025 to $7.0 million, up from $6.2 million at December 31, 2024.

 

Mr. Arnone continued, “We are continuing to pursue a robust sales pipeline comprised of multiple potential customers for the integration of our Selective Catalytic Reduction (“SCR”) technologies with power generation sources that meet the emissions control requirements for data centers planned across the U.S. over the next several years. We remain actively engaged with our supply chain partners and engineering colleagues to advance these opportunities. Our current pipeline of potential sales opportunities related to data center construction is approximately $75-100 million.”

 

The Company is continuing the extended demonstration of its DGI technology at a fish hatchery in the western U.S., which remains on track to conclude in the second quarter of 2026. The system is performing well, meeting customer expectations for the precise delivery of concentrated dissolved oxygen, and generating positive initial results. A second trial that commenced at a municipal wastewater site in the southeast U.S. was successfully completed in January 2026 and converted to a six-month demonstration rental contract that is expected to run through the third quarter of 2026.

 

Fourth Quarter 2025 (Q4 2025) Consolidated Results Overview

All comparisons are to the fourth quarter ended December 31, 2024 unless otherwise stated.

 

Consolidated revenues for Q4 2025 rose 37% to $7.2 million from $5.3 million, driven by increases in both APC and FUEL CHEM segment revenues.

 

Consolidated gross margin for Q4 2025 expanded to 44.6% of revenues from 42.3% of revenues, primarily reflecting higher APC segment gross margins.

 

SG&A expenses for Q4 2025 were $4.2 million, or 57.3% of revenues, compared to $3.9 million, or 74.7% of revenues.

 

Interest income was flat at $0.3 million and related primarily to interest received on the held-to-maturity debt securities and money market funds.

 

Net loss in Q4 2025 was $(1.2) million, or $(0.04) per share, compared to net loss of $(1.9) million, or $(0.06) per share.

 

Adjusted EBITDA loss was $(1.2) million in Q4 2025 compared to an Adjusted EBITDA loss of $(1.8) million.

 

 

 

APC segment revenue rose 37% to $2.4 million from $1.8 million, primarily related to project timing. Segment gross margin expanded to 42.3% from 35.8%, primarily due to product and project mix.

 

FUEL CHEM segment revenue rose 37% to $4.9 million from $3.5 million, primarily driven by the extended life of certain coal fired units to satisfy increasing energy demand, to the addition of the aforementioned new customer demonstration and to all base units running at capacity without interruption from unscheduled outages. Segment gross margin was 45.8% compared to 45.5%.

 

2025 Full Year Overview

 

Consolidated revenues for 2025 rose to $26.7 million from $25.1 million in 2024, driven by higher FUEL CHEM segment revenues, partially offset by a decrease in APC segment revenues.

 

Consolidated gross margin for 2025 expanded to 46.4% from 42.3% in 2024, reflecting higher APC and FUEL CHEM gross margins.

 

SG&A expenses for 2025 were $14.1 million, or 52.7% of revenues, as compared to $13.8 million, or 54.8% of revenues in 2024, reflecting an increase in employee related cost and other expenses.

 

Interest income was $1.4 million in 2025 compared to $1.3 million in 2024.

 

Net loss for 2025 was $(2.3) million, or $(0.08) per share, compared to net loss of $(1.9) million, or $(0.06) per share, in 2024.

 

Adjusted EBITDA loss was $(2.7) million in 2025 compared to Adjusted EBITDA loss of $(2.2) million in 2024.

At December 31, 2025, cash and cash equivalents were $11.9 million, short-term investments were $12.9 million, and long-term investments totaled $7.0 million. Stockholders’ equity at December 31, 2025 was $40.0 million, or $1.29 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, 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.
