Business Context and Reporting Period

This Quarterly Report on Form 10-Q covers the three and nine months ended September 30, 2025. Tecogen Inc. designs, manufactures, and maintains high-efficiency combined heat and power (CHP) systems, chillers, and heat pumps. The company operates through three segments: Products (manufacturing), Services (maintenance), and Energy Production (selling energy under long-term contracts). In July 2025, the company completed a follow-on public offering and began trading on the NYSE American.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased 27.6% in Q3 and 31.5% YTD compared to the prior year. This was driven primarily by a 114.5% increase in Products revenue (Q3), largely due to strong sales of the new hybrid-drive air-cooled chiller.
• Margin Compression: Gross margins declined significantly. Q3 gross margin dropped from 44.1% to 30.4%, and YTD margin fell from 43.1% to 36.2%. Management attributes this to increased labor and material costs, specifically related to engine replacements and testing of new technology in the Services segment.
• Operating Expenses: Operating expenses rose 27.7% in Q3 and 13.7% YTD, driven by higher payroll, recruitment, insurance, and stock-based compensation.
• Liquidity Improvement: Cash and cash equivalents increased by $9.8 million (182.2%) year-over-year, primarily due to net proceeds of approximately $18.1 million from a follow-on equity offering in July 2025.
• Debt Reduction: The company repaid all outstanding related party promissory notes (totaling $1.5 million principal plus interest) in September 2025. One note was converted to equity, and the other was repaid in cash.

Guidance, Outlook, and Risks

• Strategic Initiatives: The company is expanding into the data center cooling market, evidenced by a Sales and Marketing Agreement with Vertiv Corporation for DTx chillers. Proceeds from the recent offering are earmarked for this expansion, product development, and working capital.
• Backlog: As of September 30, 2025, the backlog for product and installation projects (excluding service contracts) was $4.0 million, down from $5.0 million in the prior year.
• Internal Controls: Management identified a material weakness in internal controls over financial reporting related to information technology general controls and segregation of duties. Remediation efforts are underway.
• Legal Proceedings: A lawsuit regarding a 2022 fire at a customer facility was settled in February 2025 for CDN $400,000, with Tecogen responsible for CDN $100,000. The liability was fully paid.
• Risk Factors: Key risks include the company's history of operating losses, reliance on a limited number of customers, supply chain constraints, and regulatory changes regarding fossil fuels in key markets like New York City.

Investor Verification Checklist

• Margin Sustainability: Verify if the decline in gross margins (particularly in Services) is a temporary result of technology testing or a structural shift due to rising input costs.
• Chiller Demand: Assess the durability of the revenue spike in the Products segment driven by the new hybrid-drive chiller and the Vertiv partnership.
• Cash Burn Rate: Monitor the rate of cash consumption from operations (which was negative $7.3 million YTD) against the new cash balance to determine runway without further capital raises.
• Internal Control Remediation: Track the progress of remediation for the material weakness in IT controls and segregation of duties to ensure future reporting reliability.
• Energy Production Segment: Review the impact of expiring contracts and site shutdowns on the Energy Production segment, which saw a 34.2% revenue decline in Q3.
