Fuel Tech, Inc. reported first-quarter 2026 revenue of $6.08M, down modestly from $6.38M a year earlier, as softer FUEL CHEM demand offset growth in air pollution control projects. APC segment revenue rose to $1.60M, while FUEL CHEM declined to $4.48M due to seasonal maintenance outages and lower dispatch at customer plants.
Consolidated gross margin slipped to 43% from 46%, and higher selling, general and administrative expenses of $3.72M led to a wider operating loss of $1.60M. Net loss increased to $1.36M, or $(0.04) per share, compared with a loss of $0.74M, or $(0.02) per share, in 2025.
Liquidity remains solid, with $9.11M in cash and cash equivalents, $21.47M in held-to-maturity investments at fair value, no financial debt and working capital of $22.17M. APC backlog was $6.92M, and management believes existing cash and expected operating cash flows are sufficient to fund operations for the next 12 months while it continues investing in DGI® water treatment technology.
Fuel Tech, Inc. reported a wider net loss for Q1 2026 as modestly lower revenue and higher expenses weighed on results, while its air pollution control business and project pipeline strengthened.
