Tecogen Announces First Quarter 2022 Results
Revenues of $ 7.4 million, Positive Income from Operations and Net Income
WALTHAM, Mass., May 12, 2022 - Tecogen Inc. (OTCQX:TGEN), a leading manufacturer of clean energy products, reported revenues of $7.4 million and net income of $89 thousand for the quarter ended March 31, 2022 compared to revenues of $6.1 million, an improvement of $1.4 million, and a net profit of $1.8 million in 2021, a decrease of $1.7 million. The positive net income in Q1 2021 was primarily due to the benefit from the CARES Act payroll support programs. The company generated $1.9 million in cash from operations during the quarter and ended the quarter with a cash balance of $5.5 million.
Key Takeaways
Net Income and Earnings Per Share
•Net income in Q1 2022 was $89 thousand compared to $1.8 million in Q1 2021, a decrease of $1.7 million, primarily due to the forgiveness of the PPP loan in Q1 2021. EPS was $0.00/share and $0.07/share in Q1 2022 and Q1 2021, respectively.
Income from Operations
•Income from operations for the three months ended March 31, 2022 was $81 thousand compared to a loss of $139 thousand for the same period in 2021, an increase of $220 thousand. Our increased revenues combined with reduced operating costs resulted in positive income from operations.
Revenues
•Revenues for the quarter ended March 31, 2022 were $7.4 million compared to $6.1 million for the same period in 2021, a 22.8% increase.
◦Product revenue was $3.9 million in Q1 2022 compared to $2.1 million in the same period in 2021, an increase of 85.6%, primarily due to increased cogeneration and chiller unit volume. We continue to see sales into our key market segments including controlled environment agriculture.
◦Services revenue was $2.9 million in Q1 2022 compared to $3.3 million in the same period in 2021, a decline of 11.1%, primarily due to reduced lower margin installation activity. Services contract revenue increased 4.8% to $2.9 million compared to $2.8 million in the first quarter of 2021.
◦Energy Production revenue decreased 11.0%, to $582 thousand in Q1 2022 compared to $653 thousand in the same period in 2021 due to site closures as a result of COVID.
Gross Profit
•Gross profit for the first quarter of 2022 was $3.1 million compared to $3.0 million in the first quarter of 2021. Gross margin reduced to 41.6% in the first quarter compared to 48.7% for the same period in 2021 due to higher material costs reducing product margin from 44.7% to 32.9%. Services margin remained comparable quarter to quarter.
Operating Expenses
•Operating expenses decreased by 2.6% to $3.01 million for the first quarter of 2022 compared to $3.09 million in the same period in 2021 due to reduced external commissions and gains on the disposal of assets and corresponding reversal of the unfavorable contract liability associated with the asset.
Adjusted EBITDA(1) was a positive $154 thousand for the first quarter of 2022 compared to $20 thousand for the first quarter of 2021. (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 saw a substantial increase in revenues this quarter and were able to produce positive operating income and net income. However we saw a significant increase in cost of goods due to the inflationary environment we presently find ourselves in. We have instituted price increases and continue to execute on our strategy of focusing on clean cooling in our key market segments including controlled environment agriculture. Our Board has formed a special committee headed by our Board member Prof. Ahmed Ghoniem to determine how Tecogen can help reduce the environmental impact of agricultural food products by expanding the use of our systems in the controlled-environment growing segment” commented Benjamin Locke, Tecogen's Chief Executive Officer.

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, 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.
