Tecogen Reports 27.6% Revenue Growth to $7.18 Million in Q3 2025

Tecogen Inc. reported significant financial developments in its latest 10-Q filing for the third quarter of 2025, showcasing a total revenue of $7.18 million, a 27.6% increase from $5.63 million in the same period last year. The growth was primarily driven by a substantial rise in product sales, particularly in chillers, which saw a remarkable increase of 5,784.1% year-over-year, contributing $2.23 million to the revenue. However, the company experienced a decline in energy production revenue, which fell by 34.2% to $255,816, attributed to the expiration of several contracts and temporary shutdowns for repairs.

In terms of profitability, Tecogen reported a consolidated net loss of $2.13 million for the quarter, compared to a loss of $930,408 in the prior year, marking a 129% increase in losses. The loss from operations also widened to $2.10 million, up from $873,223 in the same quarter of 2024. This increase in losses was largely due to rising costs associated with labor and materials, which negatively impacted gross margins, dropping to 30.4% from 44.1% year-over-year.

The company’s balance sheet showed a notable improvement in liquidity, with cash and cash equivalents increasing to $15.25 million as of September 30, 2025, up from $5.41 million at the end of 2024. This increase was bolstered by a successful public offering in July 2025, which raised approximately $18.1 million in net proceeds. The funds are earmarked for product development, marketing, and general working capital, including repayment of related party promissory notes.

Operationally, Tecogen has been expanding its service offerings, particularly through the acquisition of Aegis Energy Services, which has added maintenance contracts to its portfolio. The company has also entered into a sales and marketing agreement with Vertiv Corporation to promote its DTx chillers for data center cooling applications, indicating a strategic move to tap into the growing data center market. Despite challenges such as increased labor costs and supply chain disruptions, Tecogen remains focused on enhancing its product offerings and expanding its market reach.

Looking ahead, Tecogen anticipates continued growth driven by its innovative products and strategic partnerships. The company is optimistic about its ability to navigate market challenges and capitalize on opportunities in the energy sector, particularly as demand for efficient energy solutions increases amid rising utility costs and regulatory pressures.
