Tecogen recently provided an overview of its second-quarter financial performance for 2026, highlighting a period of strategic recalibration and investment. While overall revenue experienced a decline, primarily attributed to reduced product sales compared to the previous year's tax-incentive driven demand, the company demonstrated resilience with a notable increase in service revenue. A central theme of the report was Tecogen's intensified focus on the burgeoning hyperscale data center market, a segment it believes holds substantial growth potential. This strategic pivot involves engaging with major industry players through extensive product demonstrations and proactively building inventory to meet anticipated demand, despite current operational losses stemming from expansion and development efforts.
During the second quarter of 2026, which concluded on August 13th, Tecogen's leadership team, including General Counsel John Kimball Whiting, CEO Abinand Rangesh, and CFO Roger Deschenes, convened to discuss the company's financial results and future outlook. The earnings call revealed a total revenue of $5.75 million, marking a 21.2% decrease year-over-year. This downturn was largely driven by a 64% reduction in product revenue to $1.13 million, following a strong prior year boosted by Inflation Reduction Act tax credits. However, service revenue showed a positive trend, climbing 10.3% to $4.38 million due to increased activity and newly acquired maintenance contracts. Energy production revenue also saw a healthy 35.4% increase to $0.24 million, a result of improved operational uptime.
Despite the revenue challenges, Tecogen managed to improve its gross margin to 37.8% from 33.8% in the previous year, thanks to price adjustments and a more favorable product mix. Product gross margin, in particular, surged to 48.5% from 29.3%. Conversely, net loss for the quarter expanded to $2.15 million, and non-GAAP EPS reflected a loss of $0.07, compared to $0.06 in Q2 2025. Operating expenses rose by 11.6% to $4.32 million, largely due to investments in expanding manufacturing capacity and the ongoing development of its dual-source chiller technology. Adjusted EBITDA stood at a negative $1.68 million.
A significant portion of the discussion centered on Tecogen's strategic shift towards the hyperscale data center market. CEO Abinand Rangesh explained that the company initially targeted smaller data centers but is now directly pursuing larger, more influential clients. Over the past two months, Tecogen hosted 12 product demonstrations—six in-person and six virtual—for entities representing approximately 8 gigawatts of operational data center capacity in the U.S., accounting for 15% to 20% of the total market. These demonstrations, attended by senior data center engineers, signify a substantial commitment from potential clients. Rangesh emphasized that Tecogen’s products uniquely address critical challenges faced by data centers, such as water usage, noise pollution, and air emissions, particularly with its closed-loop dual-source chillers and low-emission cogeneration systems. The company is proactively building inventory of these chillers to shorten lead times and capitalize on the positive feedback received.
Tecogen's base business backlog has grown to over $8 million, with an additional $2 million to $3 million in projects anticipated to close soon, suggesting an expected increase in product revenue in the third quarter. The company has also implemented cost reductions in its service group, which, despite a $300,000 one-time cost related to a chiller failure, are expected to improve future margins. Management is confident that by focusing on large-scale data centers and showcasing its technology's ability to solve pressing environmental and operational issues, Tecogen is well-positioned to secure significant pilot projects, thereby shaping its future growth and maximizing shareholder value.
