Tecogen Announces Second Quarter 2019 Results

WALTHAM, Mass., August 13, 2019 - Tecogen Inc. (NASDAQ:TGEN), a leading manufacturer of clean energy products, reported revenues of $7,867,396 for the quarter ended June 30, 2019 compared to $8,453,165 for the same period in 2018, a 7% decline in top line revenue. Consolidated gross profit for the second quarter of 2019 was $3,425,915 compared to $3,159,594 in the second quarter of 2018, an increase of 8% in overall gross profit year over year, despite the revenue decline. Loss from operations for the second quarter of 2019 was $334,582, compared to $636,286 for the same period 2018, an improvement of $301,704 year over year. Net loss attributable to the Company was $357,129 for the second quarter of 2019, compared to $754,350 for the same period in 2018, an improvement of $397,221, or 53% year over year.

Product revenue results were highlighted by growth in cogeneration sales of 10% as chiller sales declined 14% year over year. Total services related revenues for the second quarter of 2019 increased by 9% over the prior year period, due to certain engineering service projects.

Overall gross margin for the second quarter of 2019 was 44% compared to 37% for the same period in 2018, above management's targeted 35-40% gross margin range. Product gross margin was 37% for the second quarter of 2019 compared to 40% for the same period in 2018. Service gross margin was 48% in the second quarter of 2019 compared to 34% for the same period in 2018 due to an increase in margins recognized on installation projects during the quarter. Energy production gross margin was 37% for the second quarter of 2019 compared to 44% for the same period in 2018.

On a combined basis, operating expenses decreased to $3,760,497 for the second quarter of 2019 from $3,795,880 in the second quarter of 2018, a decrease of $35,383. Research and development costs decreased by 9% to $372,545, while selling expenses rose 11% to $704,700. These fluctuations, along with the decrease in G&A costs of $67,453, accounted for the net decrease in operating expenses.

Adjusted EBITDA⁽¹⁾, excluding the unrealized gain or loss on marketable securities, stock-compensation expense and merger related expenses, was negative $205,030 for the second quarter of 2019 compared to negative $329,541 for the second quarter of 2018, an improvement of $124,511, or 38% year over year. Adjusted EBITDA⁽¹⁾ for the first six months of 2019 was positive $473,056 compared to negative $25,810 for the first six months of 2018, an improvement of $498,866. (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 merger related expenses. See table following the 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).

“While the second quarter has historically seen lower revenues, we made excellent progress in terms of improving our overall margins,” commented Benjamin Locke, Tecogen CEO. “Our backlog is as strong as ever, and we fully expect product sales and revenues to increase in the second half of the year with the goal of maintaining full year positive adjusted EBITDA. We are also very excited about a significant opportunity for an order for upwards of 3 megawatts of InVerde cogeneration equipment that, while not in our backlog, could be decided upon in the second half of the year with resulting equipment sales in the first half of 2020. Our growing product backlog, strong service margins, and increased interest in our Ultera emission technology is exciting for the Company, and I am very enthusiastic about our prospects for the remainder of the year and into 2020.”

Backlog of products and installations was $25 million at the end of the second quarter of 2019 and stood at $28 million as of August 9, 2019.

Emissions Technology

•

Ultera Emissions System - Forklift Truck Application. Following review of the testing from two engine tuning iterations designed to minimize emissions, Mitsubishi Caterpillar Forklift America Inc. (MCFA) and its parent company agreed to send emissions engineers to Tecogen’s facility in Massachusetts to pursue final optimization and certification as a near-zero emissions system. This collaboration is scheduled to begin during the last week of September 2019.

•

Ultera Emissions System - Stationary Engines. The Company has received an order to complete the engineering of an upsized Ultera system for use in municipal water pumping in Southern California for an 800-horsepower Caterpillar natural gas engine. This system would have more than twice the capacity of the Company’s largest system to date. The engineering has been completed and will be submitted this week for review by the water district. Orders for two upsized systems are anticipated in early 2020.


•	Ultera Emissions System - Automotive Catalyst Development. In the first phase of a program to advance the Ultera technology for mobile applications our research activities identified a promising catalyst material to improve performance of the Ultera process. Testing of the new catalyst is scheduled to conclude in September 2019.

⁽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 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 merger related expenses), which is a non-GAAP measure. The Company believes 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. 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.
