Tecogen Announces Third Quarter 2020 Results
Continued Improvement in Margin and OPEX
WALTHAM, Mass., November 12, 2020 - Tecogen Inc. (OTCQX: TGEN), a leading manufacturer of clean energy products, reported revenues of $7.20 million for the quarter ended September 30, 2020 compared to $8.67 million for the same period in 2019, a 17.0% decrease. Product revenues decreased 30% to $2.66 million compared to $3.79 million in the same period in 2019. Gross profit for the third quarter of 2020 was $2.79 million compared to $2.83 million in the third quarter of 2019. Gross margin improved to 39% for the third quarter of 2020 compared to 33% for the same period in 2019. Net loss was $232 thousand for the third quarter of 2020, compared to $586 thousand for the same period in 2019.
Key Takeaways:
| • | Gross margin increased to 38.7% for Q3 2020 versus 32.7% for Q3 2019 |
|---|---|
| • | Operating expenses decreased by $375 thousand (11.1%) to $2.99 million for the third quarter of 2020 compared to $3.37 million in the same period of 2019 |
| --- | --- |
| • | Net loss per share was $0.01 for the third quarter of 2020 and $0.02 for the third quarter of 2019 |
| --- | --- |
| • | Cash flows provided by operations of $1.57 million year to date compared to cash flows used by operations of $3.23 million for the same period in 2019 |
| --- | --- |
| • | Cash and cash equivalents at the end of the third quarter 2020 of $1.65 million compared to $780 thousand on September 30, 2019, an increase of 117%. |
| --- | --- |
Adjusted EBITDA^(1)^was negative $67 thousand for the third quarter of 2020 compared to negative $422 thousand for the third quarter of 2019. (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 due to the abandonment of certain intangible assets. See table following the statements of operations for a reconciliation from net loss to Adjusted EBITDA as well as important disclosures about the company's use of Adjusted EBITDA).
On April 17, 2020, the Company obtained a Paycheck Protection Program ("PPP") loan of $1,874,200 pursuant to the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). The proceeds were used for payroll, rent and utilities and, on November 10, 2020, an application was submitted for forgiveness of the full amount of the loan.
“During the third quarter we continued to experience challenges to our business and our customers as a result of the COVID-19 pandemic,” commented Benjamin Locke, Tecogen's Chief Executive Officer. “Our product sales in the third quarter declined primarily due to the impact of COVID-19 related delays on projects and customer purchase decision timing. Installation revenue and Energy Production revenue also decreased as we experienced COVID-19 related disruption. On the positive side, we saw record revenues from our maintenance services, and we are cautiously optimistic that our product revenues will improve for the rest of the year. We have used the slowdown in
activity to focus on improving efficiencies and reducing operating expenses, and I am encouraged we are seeing results with our improved product and service margins.”
Sales & Operations Highlights
| • | Current sales backlog of equipment and installations as of September 30, 2020 is $10.7 million, comprised of $8.1 million of products and $2.5 million of installation services |

Forward Looking Statements
This press release and accompanying documents contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 that involve risks and uncertainties. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Forward-looking
statements provide current expectations of future events based on certain assumptions and include any statement that does not directly relate to any historical or current fact. For example, statements in this press release regarding the potential future impact of the COVID-19 pandemic on the Company’s business and results of operations are forward-looking statements. Forward-looking statements can also be identified by words such as “future,” “anticipates,” “believes,” “estimates,” “expects,” “intends,” “plans,” “predicts,” “will,” “would,” “could,” “can,” “may,” and similar terms. Forward-looking statements are not guarantees of future performance and the Company’s actual results may differ significantly from the results discussed in the forward-looking statements. Such forward-looking statements include, among other things, the impact of the coronavirus pandemic on demand for our products or services, the availability of incentives, rebates and tax benefits relating to our products, changes in the regulatory environment relating to our products, competing technological developments, and the availability of financing to fund our operations and growth. Factors that might cause such differences include, but are not limited to, those discussed in Part I, Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, as supplemented, and Part II, Item 1A of the Company’s Form 10-Q for the quarter ended September 30, 2020 (“Third Quarter Form 10-Q”), in each case under the heading “Risk Factors.” The following discussion should be read in conjunction with the Third Quarter Form 10-Q filed with the Securities and Exchange Commission (“SEC”) and the unaudited condensed consolidated financial statements and accompanying notes included in Part I, Item 1 of the Third Quarter Form 10-Q. Any forward-looking statement in this release speaks only as of the date on which it is made. Except as required by law, the company assumes no obligation to update or revise any forward-looking statements.
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 principles (“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 due to 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.

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
