Fuel Tech shares fall 13.92% after hours as Q3 revenue misses estimates by 20.57% despite EPS guidance met.

Fuel Tech fell 13.92% in after-hours trading following its Q3 2025 earnings report, which revealed a 20.57% revenue shortfall against estimates despite meeting EPS expectations. The stock’s sharp decline aligned with news detailing the company’s revenue drop to $7.5 million from $7.9 million year-over-year and a 15.87% post-earnings price drop cited in the Spanish and German summaries. While Fuel Tech projected 8% 2025 revenue growth, the immediate bearish reaction stemmed from unmet quarterly revenue targets and weaker-than-expected performance, signaling investor concern over execution challenges. The earnings call transcript and detailed analysis confirmed the revenue miss as the primary driver, overshadowing longer-term growth guidance.
