Tecogen Announces 2021 Results

Net Income of $3.7 million for FY 2021 and $63.0 thousand for Q4 2021

Earnings of $0.15 per share for FY 2021

WALTHAM, Mass., March 10, 2022 - Tecogen Inc. (OTCQX:TGEN), a leading manufacturer of clean energy products, reported net income of $63.0 thousand for the quarter ended December 31, 2021 and $3.7 million for the full year compared to a net loss of $4.1 million and $6.2 million, respectively, in 2020. This represents an improvement of $4.0 million and $9.8 million respectively. The increase in net income for the quarter was due to improved operations and for the year was helped significantly by the PPP loan forgiveness and Employee Retention Credit. Our gross margin increased to 47.5% for the year ended December 31, 2021 compared to 38.3% for the same period in 2020. The company also generated positive cash flow from operations of $465 thousand in 2021 compared to $1.4 million in 2020. The year end cash balance was $3.6 million.

Key Takeaways

Earnings Per Share

•Net income (loss) per share, basic and diluted, was $0.15/share for FY 2021 and $0.00 per share for Q4 2021 compared to a loss of $0.25 and $0.16 per share for the same periods in 2020.

Income from Operations

•Operating income was $130 thousand for the quarter compared to a loss of $4.1 million during the same period in 2020. The increase in our operating income is due primarily to the increased revenue and margins for our Products Segment and increased revenue from our service contracts in the Services Segment. In the quarter ended December 31, 2021, we also saw no goodwill impairment associated with the ADGE contracts whereas for the same period in 2020 the goodwill impairment amounted to $2.9 million.

•For the year ended December 31, 2021, our loss from operations was $1.2 million compared to a loss of $6.0 million for the same period in 2020, a decrease of $4.7 million. The decrease in our loss from operations is due primarily to zero goodwill write

downs with respect our ADGE energy producing assets and to improved operations in the fourth quarter of 2021.

Revenues

•Revenues for the quarter ended December 31, 2021 were $7.2 million compared to $5.7 million for the same period in 2020, a 26.9% increase.

◦Product revenue was $3.7 million in Q4 2021 compared to $1.9 million in the same period in 2020, an increase of 92.0% primarily due to an increase in chiller sales.

◦Services revenue was $3.1 million in Q4 2021 compared to $3.3 million in the same period in 2020, a decline of 6.2% due to reduced lower margin installation activity. Service contract revenue (O&M revenue) increased to $2.9 million or 16.8% in Q4 2021 from $2.5 million during the same period in 2020.

◦Energy Production revenue decreased by $41.6 thousand, or 9.4%, to $400 thousand in Q4 2021 compared to $441 thousand in the same period in 2020.

•For the year ended December 31, 2021, revenues were $24.4 million compared to $28.3 million in FY 2020, a decrease of $3.9 million or 13.6% year over year.

◦Product revenue was $10.1 million in the 2021 compared to $11.5 million in FY 2020, a decline of 11.6%, as a result of reduced sales activities in the first half of 2021.

◦Services revenue was $12.5 million for FY 2021 compared to $15.0 million in FY 2020, a decline of 16.2% due to reduced lower margin installation activity. Service contract revenue (O&M revenue) increased 15.0% to $11.6 million for FY 2021 compared to $10.1 million in FY 2020.

◦Energy production revenue for FY 2021 was $1.7 million, compared to $1.8 million in FY 2020, a decrease of 5.3%.

Gross Profit

•Gross profit for the fourth quarter of 2021 was $3.5 million compared to $2.3 million in the fourth quarter of 2020. Gross margin improved to 48.1% in the fourth quarter of 2021 compared to 41.4% for the same period in 2020.

•Gross profit for FY 2021 was $11.6 million compared to $10.8 million for FY 2020, an increase of 7.0%. For FY 2021 gross margin increased to 47.5% compared to 38.3% for the same period in 2020 due to higher Product and Service margins.

Operating Expenses

•Operating expenses decreased by 48.7% to $3.3 million for the fourth quarter of 2021 compared to $6.5 million in the same period of 2020. Operating expenses were higher in 2020 primarily due to the impairment of long-lived assets and goodwill.

•For FY 2021 operating expenses decreased $4.0 million, or 23.7%, to $12.8 million compared to $16.8 million for FY 2020. The decrease is due primarily to the impairment of long-lived assets and goodwill recognized in 2020 and, to a lesser extent, operating expense cost controls, resulting in decreased payroll and payroll related expenses and reductions in other operating expenses compared to FY 2020.

Adjusted EBITDA was a positive $284 thousand for the fourth quarter of 2021 compared to a loss of $929 thousand for the fourth quarter of 2020. For the year ended December 31, 2021 adjusted EBITDA was a positive $0.7 million compared to a negative $2.2 million for FY 2020. The FY 2021 adjusted EBITDA benefited from $1.2m million of Employee Retention Credit. (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).

“We had a significantly improved 4th quarter and year in 2021 compared to 2020” commented Benjamin Locke, Tecogen's Chief Executive Officer. “As COVID effects recede, our business has started to rebound. We have also been seeing improved sales as a result of our strategic focus on key market segments such as controlled environment agriculture, healthcare and multifamily. Our chiller product in particular has seen significant penetration in the cannabis cultivation space. More than 45% of our current backlog is in this high growth market.”

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 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.

(2) Employee Retention Credit

The adjusted EBITDA in 2021 benefits from $1.2 million of Employee Retention Credit.

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
