Abinand Rangesh, CEO of Tecogen, commented "during the upcoming call, I will provide some significant positive updates that will include the scale of the Vertiv opportunity pipeline for our chillers, the status of our own data center opportunities and an upcoming pilot project.

On other positive news, our revenue grew 20% year on year. Although our loss widened and cash burn increased, this was because of critical expenses needed to expand margins in the service business and to develop the data center opportunities including expanding manufacturing capacity, R&D on our data center dual power source chiller and marketing."

⁽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.
