Tecogen Reports Second Quarter 2025 Financial Results

NORTH BILLERICA, MA / ACCESS Newswire / August 12, 2025 / Tecogen Inc. (NYSE American:TGEN), a leading manufacturer of clean energy products, reported revenues of $7.29 million and net loss of $1.47 million for the quarter ended June 30, 2025 compared to revenues of $4.73 million, and a net loss of $1.54 million in 2024. Our cash and cash equivalents balance was $1.64 million at June 30, 2025.

Abinand Rangesh, CEO of Tecogen, commented that "since our last earnings call we have made tremendous progress with our data center strategy and achieved several key milestones. We received our first LOI for a great pilot project. This is for a 100+MW data center with the potential to be a 500+MW site. The customer expects to evaluate 6 STx chillers during the first phase of the project. If successful, more chillers will be used in subsequent phases. We expect the LOI to convert to a PO later this year and we hope to grow with this customer.

In the last three months, our marketing has generated great leads. We have now quoted two projects for 60 to 100 chillers each. We have multiple other projects that are earlier stage but have similar potential. We've also received feedback on how customers are making purchasing decisions. During the call, I will address what these are and the steps we are taking so we can convert these leads into orders.

The only setback this quarter was the reduction in the gross profit margin which drove the net loss. Product margin was lower because we started shipping the hybrid air-cooled chiller. As expected, the first few units had higher costs due to low volume material purchasing and as our team gained experience building the product. We expect the hybrid chiller margin to increase with volume production. The other products shipped this quarter had similar margins as previous quarters.

Overall service margin declined because of one region - Manhattan and NJ. This was in part due to bulk oil system upgrades for our InVerde fleet. This has a short term impact on profitability but increases service intervals by 150% to 200%. We also experienced increased overtime hours. During the call, we will discuss the new protocols we have implemented to restore this territory to profitability.

Given the size of potential projects, the ability to manufacture and ship significant volumes of chillers is critical. We have hired talent in manufacturing and engineering. The additional staffing was a significant factor in our increased operating expenses, which increased by 9% in Q2 2025 compared to last year. To provide the necessary capital to scale our business, we also raised $18.2 million in July. The capital raised will be used to increase factory output and for marketing. I will share more details on the data center projects, Vertiv and scale up plan tomorrow."

In addition to those factors described in our Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q and in our Current reports on Form 8-K, under "Risk Factors," and elsewhere therein, among the factors that could cause actual results to differ materially from past and projected future results are the following: fluctuations in demand for our products and services, competing technological developments, issues relating to research and development, the availability of incentives, rebates, and tax benefits relating to our products and services, changes in the regulatory environment relating to our products and services, integration of acquired business operations, the impact of tariffs, and the ability to obtain financing on favorable terms to fund existing operations and anticipated growth.

⁽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.
