Tecogen Announces Fourth Quarter 2023 Results
Q4 2023 revenue of $5.9 million, an increase of 30.2% QoQ

WALTHAM, Mass., March 14, 2024 - Tecogen Inc. (OTCQX:TGEN), a leading manufacturer of clean energy products, reported revenues of $5.9 million and a net loss of $1.8 million for the quarter ended December 31, 2023 compared to revenues of $4.5 million, and a net loss of $1.4 million in 2022. The increase in net loss was primarily driven by an increase in bad debt reserves for installation projects from 2017 and increase in reserves for obsolete inventory.
Our Adjusted EBITDA loss narrowed to $527 thousand for the quarter ended December 31, 2023 compared to $1.1 million in 2022. For the year ended December 31, 2023 revenues were $25.1 million and the net loss was $4.5 million compared to revenues of $25.0 million, and net loss of $2.4 million for the same period in 2022. For the year the Adjusted EBITDA loss was $2.6 million in 2023 and $1.7 million respectively in 2022.
"During the 4th quarter we had positive cash flow from operations and a recovery in gross margin for our Services segment. We continue to execute on our strategy of increasing recurring cash flow from Energy and Services to cover our fixed costs. This will allow us to be cash flow positive while we secure profitable large dollar value projects.

Unlike in the past where our sales were predominantly small cogeneration projects for residential buildings in New York City, we are now seeing the market shift to multiple unit chiller and cogeneration projects nationwide. We recently received a 6 unit (3 hybrid chillers and 3 Inverde cogeneration units) as well as a 12 unit cogeneration order. We are now focused on securing additional multiple unit product orders that we expect will result in sustained profitability and growth. In fact, we are specified on large chiller projects for some iconic facilities that are on track to close later this year.

We are also receiving significant interest from customers who are limited in electrical capacity or facing sharp increases in peak electricity charges. We expect customer pain point to increase as electrification efforts place higher pressure on the ability of utilities to supply sufficient power. As a result, our proprietary software and utility demand response capabilities will give us a competitive advantage in securing new product orders and increased Services revenue.

Although we showed a significant net loss in Q4, this was driven by a $1 million increase in bad debt expense associated with old installation project receivables and obsolete inventory. We also performed much needed work on replacing engines in the Services fleet and site improvement work within our energy fleet. These costs and the obsolete inventory reserve drove down gross profit margins but are an essential investment to improve unit runtime going forward.

We have $1 million remaining on our credit line which will help us execute our factory move later this quarter, and our present cash position of $1.1 million." commented Abinand Rangesh, Tecogen's Chief Executive Officer.

Net Loss and Earnings Per Share
•Net loss in Q4 2023 was $1.8 million compared to net loss of $1.4 million in Q4 2022, an increase of $0.4 million, primarily due to increased operating expenses. EPS was a net loss of $0.07/share and a net loss of $0.06 in Q4 2023 and Q4 2022, respectively.
•Net loss for the year ended December 31, 2023 was $4.6 million compared to net loss of $2.4 million in the comparable 2022 period, an increase of $2.2 million, due primarily to lower Products segment revenue and gross profit and an increase in operating expenses. EPS was a net loss of $0.19/share for the year ended December 31, 2023 compared to $0.10/share in 2022.
Loss from Operations
•Loss from operations for Q4 2023 increased to $1.8 million compared to a loss of $1.4 million for the same period in 2022 due to higher operating expenses.







•Loss from operations for the year ended December 31, 2023 was $4.4 million compared to a loss of $2.3 million for the same period in 2022, an increase of $2.1 million. The loss from operations increased due to lower revenue and gross profit margins in our Products segment and increased operating expenses.
Gross Profit and Gross Margin
•Gross profit for Q4 2023 was $2.3 million compared to $2.4 million in the fourth quarter of 2022. Gross margin was 39.8% in Q4 2023 quarter compared to 52.5% for the same period in 2022. Products margin decreased to 19.4% from 32.1% due to an increase in the provision for obsolete inventory, higher material costs, and increased product warranty costs. Services margin decreased to 51.3% from 60.1%, due to increased labor and material costs and an increase in the provision for obsolete inventory. In particular, as supply chain constraints for engines eased, we performed significant engine related replacements and upgrades which negatively impacted Service margins. Energy Production margin decreased to 30.3% in Q4 2023 from 47.7% in the comparable period in 2022 due to increased costs incurred to repair certain of our energy sites.
•Gross profit for the year ended December 31, 2023 decreased to $10.2 million compared to $11.1 million in the same period in 2022, a decrease of $0.9 million. Gross margin decreased to 40.6% in the year ended December 31, 2023 compared to 44.3% for the same period in 2022. Products margin decreased to 33.1% from 33.5%, due primarily to increased provisions for obsolete inventory. Services margin decreased to 45.5% from 54.2%, due to increased labor and material costs and an increase in the provision for obsolete inventory. In particular, as supply chain constraints for engines eased, we performed a significant number of engine replacements in the year ended December 31, 2023 which negatively impacted Services margins. Energy Production margin deceased to 37.1% from 44.2% due to increased costs incurred to repair certain of our energy sites.

Operating Expenses

•Operating expenses increased 10.2% to $4.2 million in Q4 2023 compared to $3.8 million in the same period in 2022 due primarily to an increase in bad debt expense, due to certain install receivables which were deemed uncollectible, increases in depreciation and amortization, travel, and business insurance, which are attributable in part to the Aegis acquisition.
•Operating expenses increased by $1.2 million, or 8.9% to $14.6 million for the year ended December 31, 2023 compared to $13.4 million in the same period in 2022 due primarily to an increase in bad debt expense due to certain install receivables which were deemed uncollectible, increases in depreciation and amortization, travel, and business insurance, which are attributable in part to the Aegis acquisition.

(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, extinguishment of debt, inventory writedown and bad debt provision), 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.
