FOR IMMEDIATE RELEASE

FUEL TECH REPORTS 2024 THIRD QUARTER FINANCIAL RESULTS

WARRENVILLE, Ill. – November 6, 2024 - Fuel Tech, Inc. (NASDAQ: FTEK), a technology company providing advanced engineering for the optimization of combustion systems, emissions control, and water treatment in utility and industrial applications, today reported financial results for the third quarter ended September 30, 2024 (Q3 2024).

“Our third quarter results included a return to profitable operations, fostering new customer relationships, and a focus on balancing expense discipline with targeted investments in new technologies,” said Vincent J. Arnone, President and CEO. “Our financial position at September 30, 2024 was strong, with $31.3 million in cash and investments and no debt.”

Mr. Arnone continued, “We realized improved quarter-over-quarter performance at our FUEL CHEM® business segment in the 2024 third quarter and in the current fourth quarter commenced a new commercial program after a successful demonstration of our TIFI® Targeted In-Furnace Injection™ technology. The annual revenue potential from this commercial contract is projected to be approximately $1.5 to $2.0 million based on the customer running the program full-time, with the revenue expected to generate historic FUEL CHEM® gross margins. We are pursuing additional opportunities to showcase our chemical technologies at additional domestic sites and currently expect to commence a demonstration of our TIFI® technology in early 2025 at a potential new client in the Midwest United States. We believe that the innovative approach of our fireside treatment program to reduce downtime, improve plant operations and provide a return on investment while helping customers meet emission regulatory requirements is resonating.

“Revenues in our Air Pollution Control (APC) business declined quarter-over-quarter, due primarily to customer-driven delays and project timing. We were pleased to announce $2.0 million of new APC orders earlier today and hope to close several new APC orders by the end of 2024 or early 2025.”

He concluded, “We are also continuing to pursue the growth and development of our Dissolved Gas Infusion (DGITM) technology. We had a very successful exhibition of DGITM at the Water Environment Federation Technical Exhibition and Conference, or WEFTEC, in New Orleans last month, and generated significant interest in the technology. With respect to product demonstrations, discussions are progressing with one of the largest food processors in the country to utilize DGITM to provide dissolved oxygen for the wastewater treatment facility at a food processing plant that they own and operate, and also with a municipal wastewater treatment facility in the Southeastern United States. Lastly, we are pleased to note that we have finalized a demonstration agreement with a U.S. fish hatchery to highlight the capabilities of DGITM for this aquaculture application, with the demonstration start date targeted at the beginning of the second quarter of 2025 to coincide with the hatchery’s next growth cycle.”

Q3 2024 Consolidated Results Overview

Consolidated revenues for Q3 2024 declined to $7.9 million from $8.0 million in the three months ended September 30, 2023 (Q3 2023), reflecting higher FUEL CHEM revenue offset by a decrease in APC revenue.

Consolidated gross margin for Q3 2024 declined to 43.4% of revenues from 45.2% of revenues in Q3 2023, primarily due to lower APC gross margin while FUEL CHEM gross margin remained steady.

SG&A expenses increased to $3.2 million from $3.0 million in Q3 2023, primarily reflecting increases in employee compensation and benefit related costs and higher administrative expenses, partially offset by decreases in international administrative expenses. As a percentage of revenues, SG&A expenses rose to 41.1% in Q3 2024 from 37.1% in Q3 2023.

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 income in Q3 2024 was $80,000, or $0.00 per share, compared to net income of $459,000, or $0.01 per share, in Q3 2023.

Consolidated APC segment backlog at September 30, 2024 was $6.4 million compared to $7.5 million at December 31, 2023, and did not include the aforementioned $2.0 million of new APC contracts.

APC segment revenue declined to $3.2 million from $3.7 million in Q3 2023, primarily related to customer driven delays in project execution and to the timing of new contract awards. APC gross margin decreased to 35.0% from 40.3%, primarily due to product and project mix.

FUEL CHEM segment revenue rose to $4.6 million from $4.3 million in Q3 2023, reflecting customer outage completions and increased dispatch. Gross margin was steady at 49%.

Adjusted EBITDA loss was $(35,000) compared to Adjusted EBITDA of $352,000 in Q3 2023.

At September 30, 2024, cash and cash equivalents were $12.3 million, short-term investments were $8.2 million, and long-term investments totaled $10.9 million. Stockholders’ equity at September 30, 2024 was $43.9 million, or $1.42 per share, and the Company had no debt.

RECONCILIATION OF GAAP NET INCOME (LOSS) TO EBITDA AND ADJUSTED EBITDA

(Unaudited)

(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 gain on employee retention credit. 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.
