Analysis
Tecogen reported third quarter 2026 total revenues of $7,873,820, up from $7,183,121 a year earlier, and a net loss attributable to Tecogen Inc. of $(1,589,568) compared with $(2,130,947). The quarter's improvement came mainly from Services, where revenue rose to $4,462,607 from $3,943,510, and from Energy production, which rose 42.0%. Products revenue increased 2.2% to $3,047,954. The company attributes the Services increase to the acquired Aegis maintenance contracts and to existing service contracts. Gross margin for the quarter was 37.4% against 30.4% a year earlier, which the company ties to higher Services segment margin.
The nine-month picture is weaker. Total revenues were $19,955,725 against $21,755,712, a decline of 8.3%, driven by Products revenue, which fell 38.2% to $5,358,026. Services and Energy production grew over the nine months, by 10.9% and 20.9% respectively. Gross profit was $7,709,509 against $7,867,099, although the nine-month gross margin of 38.6% was above the 36.2% printed for the prior year. Operating expenses rose 13.3% to $13,561,980, with general and administrative expenses at $10,953,622 against $9,431,073. The loss from operations for nine months widened to $(5,852,471) from $(4,106,810), and the nine-month net loss attributable to Tecogen Inc. was $(5,858,744) against $(4,254,974).
Adjusted EBITDA, a non-GAAP measure, was $(1,007,288) for the quarter against $(1,674,092) a year earlier, and $(4,370,484) for nine months against $(3,216,384). Net loss per share was $(0.05) for the quarter and $(0.20) for nine months, against $(0.07) and $(0.16) in the prior-year periods.
Cash flow and liquidity deserve attention. Net cash used in operating activities was $(6,846,543) for nine months, and cash and cash equivalents fell to $5,333,436 from $12,430,287 at December 31, 2025. Total stockholders' equity declined to $16,264,888 from $21,472,612. The filing shows no share repurchases or dividends. The company reports deferred revenue of $1,328,096 (current) and $3,118,340 (non-current), and the CEO says customer deposits contributed to a higher cash position after quarter end, a figure given in the call remarks and not in the financial statements.
The filing contains no financial guidance. The CEO described a backlog of more than $8m, with over 70% from large property portfolio owners and energy services companies, and referred to a data center pipeline and a dual power source retrofit product to be discussed on the call. These are company statements and are not reflected in the reported financial tables. Overall, the quarter shows improvement in revenue, margin and loss, while the nine-month trend, cash decline and operating cash outflow remain unresolved in the filing.
Management, verbatim
In addition, the backlog is presently more than $8m.

The higher revenue and customer deposits means that our current cash position has increased to $5.7m today with a further $800k expected to be collected in the next two weeks.
