In Q1 2025, Fuel Tech’s consolidated revenue rose 29% to $6.4 million, driven predominantly by a 92% increase in Fuel Chem revenues to $5.1 million. This surge reflects the return to full operational capacity of base accounts and contributions from a new commercial customer added in late 2024. Conversely, APC revenues declined 44% to $1.3 million due to timing delays in project execution and contract awards. Gross margin expanded to 46.4%, boosted by Fuel Chem’s improved margin profile, despite a decline in APC segment margins.
Operating expenses remained stable at $3.3 million, leading to a narrowed operating loss of $1.0 million. The company reported a net loss of $739,000, which is an improvement when adjusted for one-time income in the prior year. A notable highlight is the 66% increase in APC backlog to $10.3 million, the highest since 2022, reflecting strong order momentum and improved visibility into future revenue streams.
- Revenue Composition Shift: Fuel Chem now dominates revenue, underscoring a strategic pivot toward chemical technology solutions.
- Backlog Growth as Leading Indicator: The substantial backlog increase signals accelerating APC contract awards despite recent revenue softness.

Strategic Positioning
1. Fuel Chem Segment as Growth Engine
Fuel Tech is capitalizing on renewed demand from coal-fired utilities seeking to optimize plant operations and reduce downtime. The segment’s performance is underpinned by stable base accounts operating without unplanned outages and the onboarding of a new commercial customer. The company is actively pursuing additional accounts, including a potential demonstration of the TIFI® Targeted In-Furnace Injection technology scheduled for late Q3 2025, with commercial agreements anticipated by year-end or early 2026.
2. Air Pollution Control Segment Recovery and Opportunity Pipeline
Although APC revenues declined due to project timing, management highlights a strong pipeline with recent $1.6 million contract awards and expectations for an additional $4 to $5 million in awards by early Q2. These contracts span the company’s SCR, ULTRA®, and SNCR technologies, targeting industrial expansion and state-driven regulatory compliance, including municipal solid waste combustion and data center power generation markets. The latter represents a significant growth opportunity supported by the rapid development of data centers requiring nitrogen oxide emission controls on natural gas engines.
3. Commercialization of DGI Water Treatment Technology
Dissolved Gas Infusion (DGI®) technology is progressing toward commercialization with an extended demonstration commencing in Q2 2025 at a fish hatchery. The company is engaging multiple potential customers across wastewater, pulp and paper, food and beverage, and horticulture sectors. Early revenue generation, including potential rental arrangements, is expected in 2025, signaling diversification of Fuel Tech’s technology portfolio.
4. Strong Financial Position Enables Strategic Flexibility
With $31.2 million in cash, cash equivalents, and investments, and no long-term debt, Fuel Tech maintains a robust balance sheet.
