Tecogen Inc (NYSEARCA:TGEN) released its third quarter 2025 financial results, delivering a mixed performance that saw revenue exceed analyst expectations while losses widened beyond forecasts. The clean energy manufacturer reported significant progress in its data center initiatives, though this came alongside increased operational spending and compressed margins.
Revenue Performance vs. Estimates
The company posted third quarter revenues of $7.18 million, representing a substantial 27.6% increase compared to the $5.63 million reported in the same period last year. This top-line performance notably surpassed analyst expectations, which had projected revenue of approximately $6.81 million.
Key revenue drivers for the quarter included:
- Product revenue surged 114.5% to $2.98 million, driven by increased sales of chillers, cogeneration products, and engineered accessories
- Service revenue showed modest growth of 2.4% to $3.94 million
- Energy production revenue declined 34.2% to $0.26 million due to contract expirations and temporary site shutdowns
Earnings and Profitability Metrics
While revenue growth was strong, profitability metrics showed deterioration during the quarter. The company reported a net loss of $2.13 million, significantly wider than the $0.93 million loss in Q3 2024. On a per-share basis, this translated to a loss of $0.07, which exceeded the analyst estimate of a $0.051 loss per share.
The company's financial performance revealed several pressure points:
- Gross margin declined to 30.4% from 44.1% in the prior year period
- Operating expenses increased 27.7% to $4.28 million due to higher payroll, benefits, and sales commissions
- Adjusted EBITDA was negative $1.77 million compared to negative $0.75 million in Q3 2024
Strategic Developments and Outlook
Management commentary highlighted significant progress in several strategic initiatives, particularly in the data center cooling market. CEO Abinand Rangesh noted that a potential data center customer with an existing letter of intent is now considering Tecogen for three sites and a larger portion of AI load, which could result in substantially more chiller sales than originally anticipated.
Additional strategic developments include:
- Engagement with larger, more established data center developers with multiple construction projects
- Positive developments in the relationship with Vertiv, a global provider of critical digital infrastructure
- Presentations to major AI chip manufacturers that received positive feedback
- Increased R&D spending to enhance natural gas cooling technology and extend service intervals
The company ended the quarter with a strengthened balance sheet, showing cash and cash equivalents of $15.25 million, up from $5.41 million at year-end 2024, following a July 2025 follow-on offering.
Market Reaction and Analyst Expectations
The market reaction to the earnings release has been notably positive, with the stock showing significant after-hours strength. This suggests investors may be focusing on the revenue beat and strategic progress in the data center market rather than the widened losses.
Looking ahead, analysts currently project:
- Q4 2025 revenue of approximately $7.42 million
- Q4 2025 EPS of -$0.041
- Full-year 2025 revenue of approximately $29.10 million
The company's strategic positioning in the growing data center cooling market, particularly for AI applications, appears to be generating investor optimism despite the current profitability challenges.
