Tecogen Reports First Quarter 2026 Financial Results

NORTH BILLERICA, MA / ACCESS Newswire / May 12, 2026 / Tecogen Inc. (NYSE American:TGEN), a leading manufacturer of clean energy products, reported revenues of $6.34 million and net loss of $2.12 million for the quarter ended March 31, 2026 compared to revenues of $7.28 million, and a net loss of $0.66 million in 2025. Our cash and cash equivalents balance was $9.33 million at March 31, 2026.

Abinand Rangesh, CEO of Tecogen, commented, "We delivered strong progress over the last two months, highlighted by an imminent purchase order from Vertiv for a real-world operating deployment of a 1 MW chiller system. This represents an important step that deepens our partnership and validates growing demand for our technology."

"The chillers will be permanently deployed at one of Vertiv's facilities where it solves power constraints. The installation will allow prospective customers to observe the system in use and support broader customer adoption discussions."

"Building on this momentum, we are actively advancing multiple data center opportunities. As part of this process, we are hosting prospective customers at our factory in the coming weeks for detailed, in-person reviews of our technology and system performance. Engagements that reach this stage of on-site customer evaluation typically represent later phases of due diligence prior to purchasing decisions."

"Operationally, gross profit margin expanded to >40% compared to the end of last year and we are executing on cost reductions to streamline expenses, with the full impact of these cuts expected in the third quarter of this year. We also expect our cash burn to be lower in the coming quarters as a result of these cuts and expected customer deposits."

"Beyond data centers, we are capturing demand driven by broader power constraints across the country. We have recently secured or expect to secure more than $8 million in orders. These opportunities, which are incremental to our core data center focus, have the potential to contribute to revenue and cash flow in the near-term."

Key Takeaways

Net loss for the quarter ended March 31, 2026 was $2.12 million compared to a net loss of $0.66 million for the same period of 2025, an increase of $1.46 million, due to lower Products segment revenue and gross profit, lower Services segment gross profit and increased operating expenses.

Story Continues

Loss from operations for the quarter ended March 31, 2026 was $2.14 million compared to a loss from operations of $0.59 million for the same period in 2025, an increase of $1.54 million, due to lower Products segment revenue and gross profit, lower Services segment gross profit, and increased operating expenses.

The decrease in revenue during the quarter ended March 31, 2026 is due to decreased chiller and cogeneration revenue. Services revenues in the quarter ended March 31, 2026 were $4.64 million, compared to $4.25 million for the same period in 2025, an increase of 9.2% due to increased revenues from existing contracts.

The increase in Energy Production revenue is due to increased run hours at certain energy production sites.

Gross margin decreased to 40.9% in the quarter ended March 31, 2026 compared to 44.3% for the same period in 2025.

Operating Expenses

Operating expenses increased $0.91 million, or 23.9%, to $4.73 million in the quarter ended March 31, 2026 compared to $3.82 million in the same period in 2025, due to a general increase in spending, including research costs incurred to continue to improve and refine the hybrid-drive air-cooled chiller.

(1) Non-GAAP Financial Measures

In addition to reporting net income, a U.S. generally accepted accounting principle ("GAAP") measure, this news release contains information about Adjusted EBITDA (net income (loss) attributable to Tecogen Inc adjusted for interest, income taxes, depreciation and amortization, stock-based compensation expense, unrealized gain or loss on investment securities, goodwill impairment charges and other non-cash non-recurring charges including abandonment of certain intangible assets), which is a non-GAAP measure. The Company believes Adjusted EBITDA allows investors to view its performance in a manner similar to the methods used by management and provides additional insight into its operating results. Adjusted EBITDA is not calculated through the application of GAAP. Accordingly, it should not be considered as a substitute for the GAAP measure of net income and, therefore, should not be used in isolation of, but in conjunction with, the GAAP measure. The use of any non-GAAP measure may produce results that vary from the GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies.
