Diluted earnings per share of $0.14/share YTD 2021 and $0.06/share for Q3 2021
WALTHAM, Mass., November 10, 2021 - Tecogen Inc.

Loss from Operations
•Our loss from operations for the three months ended September 30, 2021 was $0.9 million compared to a loss of $0.2 million for the same period in 2020, an increase of $0.7 million. The increase in our loss from operations is due primarily to the lower revenue for our Products and Services Segment and our Energy Production Segment and an increase in operating expenses.
•For the nine months ended September 30, 2021, our loss from operations was $1.4 million compared to a loss of $1.8 million for the same period in 2020, a decrease of $0.5 million. The decrease in our loss from operations is due primarily to the $0.8 decrease in operating expenses.
Adjusted EBITDA(1) was a negative $197 thousand for the third quarter of 2021 compared to negative $67 thousand for the third quarter of 2020. For the nine months ended September 30, 2021 adjusted EBITDA was a positive $0.4 million compared to a negative $1.2 million for the nine months ended September 30, 2020. (Adjusted EBITDA is defined as net income or loss attributable to Tecogen, adjusted for interest, income taxes, depreciation and amortization, stock-based compensation expense, unrealized gain or loss on equity securities, goodwill impairment
charges and other non-cash non-recurring charges or gains including abandonment of intangible assets and the extinguishment of debt. See the table following the Condensed Consolidated Statements of Operations for a reconciliation from net income (loss) to Adjusted EBITDA, as well as important disclosures about the company's use of Adjusted EBITDA).
“This quarter was challenging due to the significant supply chain impacts on our Product Segment. We have mitigated a majority of these impacts, but were unable to ship some product during Q3 due to supplier constraints. As a result our Product Segment revenue was significantly impacted,” commented Benjamin Locke, Tecogen's Chief Executive Officer. “We expect Product sales to rebound in the fourth quarter of 2021 and further into 2022. We are pleased with the recent announcement of an order for 12 Inverde E+ units and 3 chillers which are scheduled to be shipped during Q4 2021 and Q1 2022. Our Energy Production assets are gradually returning to normal operation as COVID related closures and restrictions are eased, and our Service maintenance revenues continue to grow each quarter. Our board and management team are cautiously optimistic regarding anticipated improvements to product sales as evidenced by one Board member's decision to acquire an additional 150,000 shares of equity in the company on October 27, 2021 at the current market price."
Operational Highlights:
•Issued a press release on November 10, 2021 announcing an order for 12 InVerde E+ units and 3 Tecochill chillers which are scheduled to be shipped during Q4 2021 and Q1 2022.
•Recognized Employee Retention Credits of $0.6 million and $1.3 million, respectively, in the third quarter and in the nine months of 2021.
•Paycheck Protection Program Second Draw Loan forgiven in full on September 8, 2021.

Forward Looking Statements
This press release and any accompanying documents, contain “forward-looking statements” which may describe strategies, goals, outlooks or other non-historical matters, or projected revenues, income, returns or other financial measures, that may include words such as "believe," "expect," "anticipate," "intend," "plan," "estimate," "project," "target," "potential," "will," "should," "could," "likely," or "may" and similar expressions intended to identify forward-looking statements. These statements are only predictions and involve known and unknown risks, uncertainties, and other factors that may cause our actual results to differ materially from those expressed or implied by such forward-looking statements. Given these uncertainties, you should not place undue reliance on these forward-looking statements. Forward-looking statements speak only as of the date on which they are made, and we undertake no obligation to update or revise any forward-looking statements.
In addition to those factors described in our Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q and on our Form 8-K filed on November 10, 2021, under “Risk Factors”, 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, and the ability to obtain financing on favorable terms to fund existing operations and anticipated growth.
In addition to GAAP financial measures, this press release includes certain non-GAAP financial measures, including adjusted EBITDA which excludes certain expenses as described in the presentation. We use Adjusted EBITDA as an internal measure of business operating performance and believe that the presentation of non-GAAP financial measures provides a meaningful perspective of the underlying operating performance of our current business and enables investors to better understand and evaluate our historical and prospective operating performance by eliminating items that vary from period to period without correlation to our core operating performance and highlights trends in our business that may not otherwise be apparent when relying solely on GAAP financial measures.

(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 and extinguishment of debt), 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.

SAFE HARBOR STATEMENT This presentation and accompanying documents contain “forward-looking statements” which may describe strategies, goals, outlooks or other non- historical matters, or projected revenues, income, returns or other financial measures, that may include words such as "believe," "expect," "anticipate," "intend," "plan," "estimate," "project," "target," "potential," "will," "should," "could," "likely," or "may" and similar expressions intended to identify forward-looking statements. These statements are only predictions and involve known and unknown risks, uncertainties, and other factors that may cause our actual results to differ materially from those expressed or implied by such forward-looking statements. Given these uncertainties, you should not place undue reliance on these forward-looking statements. Forward-looking statements speak only as of the date on which they are made, and we undertake no obligation to update or revise any forward-looking statements. In addition to those factors described in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q under “Risk Factors”, 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, and the ability to obtain financing on favorable terms to fund existing operations and anticipated growth. In addition to GAAP financial measures, this presentation includes certain non-GAAP financial measures, including adjusted EBITDA which excludes certain expenses as described in the presentation. We use Adjusted EBITDA as an internal measure of business operating performance and believe that the presentation of non-GAAP financial measures provides a meaningful perspective of the underlying operating performance of our current business and enables investors to better understand and evaluate our historical and prospective operating performance by eliminating items that vary from period to period without correlation to our core operating performance and highlights trends in our business that may not otherwise be apparent when relying solely on GAAP financial measures. 3
