Tecogen Reports Record Revenues for Full Year 2018 Generates Fourth Quarter '18 Adjusted EBITDA(1) of $502 thousand WALTHAM, Mass., March 28, 2019, Tecogen® Inc. (NASDAQ:TGEN, the "Company"), a leading manufacturer of clean energy products which, through patented technology, nearly eliminate criteria pollutants and significantly reduce a customer's carbon footprint, reported record revenues of $35,883,684 for the year ended December 31, 2018 compared to $33,202,666 for the same period in 2017, an 8% increase. Chiller sales of $7,157,771 led the year's product sales with an increase of $2,352,039, or 49%. Gross profit increased to $13,591,862 for the year ended December 31, 2018 compared to $12,954,404 for the prior year, a 4.9% improvement. Gross margin for 2018 was 38% compared to 39% for 2017. Fourth quarter revenues were $9,316,408, a decrease of 9%, year over year, while overall gross margin for the fourth quarter of 2018 increased to 40% compared to 37% for the same period in the prior year. Net income attributable to Tecogen Inc. for Q4 2018, exclusive of goodwill impairment, was $18.7 thousand compared to $269.0 thousand for Q4 2017. Operating expenses in 2018 before goodwill impairment increased 7% as compared to Q4 2017. Much of the increase in operating expenses was associated with legal fees in connection with the acquisition of American DG Energy Inc., as well as selling expenses incurred from our increased focus on chiller sales. Excluding non-recurring merger related costs, goodwill impairment, mark to market adjustments and stock compensation expense, adjusted non-GAAP EBITDA(1) was $502,160 and $217,454 for the quarter and year ended December 31, 2018, respectively, compared to $532,765 and $1,102,780 for the quarter and year ended December 31, 2017. In May 2018, the Company secured a commercial line of credit for up to $10 million, with a three year term. The availability of funds is based on the Company's accounts receivable and inventory. Concurrent with establishing this credit line, the Company repaid its note due to a related party in the amount of $850,000, plus the related accrued interest. The Company completed the sale of eight American DG Energy power purchase agreements and related assets for an aggregate price of $7 million to a company managed by an investment firm in the energy efficiency and decentralized generation market. Tecogen will continue to provide maintenance for the equipment and various administrative tasks for the duration of the power purchase agreements. Performance incentives were also included for energy savings in excess of agreed minimums, which will be split evenly by both parties. 1
CEO Benjamin Locke noted, "2018 was a transformational year for the Company. We adjusted our product mix and sales strategy to maximize our opportunity with our exclusive natural gas engine cooling technology, substantially improved the profitability of the ADG fleet, and made significant progress developing our Ultera emissions technology for fork truck and automotive applications. Our recent transaction strengthened our balance sheet and puts us in an excellent position to achieve our 2019 goals." 2018 Major Highlights: Financial • Revenue for the year ended December 31, 2018 was a record $35.9 million compared to $33.2 million for the same period in 2017, an increase of 8%. • Product revenue for the full year 2018 was $12.6 million compared to $13.0 million for the full year 2017, a decrease of 2.8%. Chiller sales were at the record level of $7.2 million, an increase of 49% over 2017. Cogeneration sales declined by 33% in 2018, compared to 2017. • Service revenue for the full year 2018 was $16.9 million, showing 3% growth from the $16.4 million in service-related revenues in 2017. Full year 2018 service revenue benefited from 5% growth in installations revenue as the Company's turnkey installation offerings continue to gain traction with customers. • Full year 2018 consolidated gross margin was 38% compared to 39% in 2017; and despite the slight decrease in margin, the year delivered a 5% year-on-year increase in gross profit dollars. • Energy production revenue for the year ended December 31, 2018 was $6.4 million, providing a gross margin of 41% and gross profit of $2.6 million. • The Company recorded goodwill impairment in the fourth quarter of 2018 in the amount of $4.4 million, which represents the excess of the carrying value of the Company's energy production reporting unit over its estimated fair value based on discounted cash flow analysis. Prior to the impairment, the goodwill asset associated with the energy production reporting unit was $13.3 million. As of December 31, 2018 goodwill associated with the energy production reporting unit was $8.9 million. • Net income before goodwill impairment for Q4 2018 was $18,686 compared to comprehensive income of $288,662 for the same period in 2017. Net loss before goodwill impairment for the year 2018 was $1.3 million compared to a comprehensive loss of $117,881 for the year 2017. Sales and Operations • Sales backlog of product and installation projects grew to $16.6 million at year end 2018 compared to $15.7 million at year end 2017. Product and installation backlog is $29.9 million as of March 25, 2019, with product related backlog at $15.4 million and installation backlog at $14.5 million. • Chiller revenue for Q4 2018 was $2,952,482 compared to $2,433,620 for Q4 2017, an increase of 21%. Cogeneration sales for Q4 2018 were $750,128, a decline of 66% when compared to Q4 2017, a result of both sales timing and an overall shift in product mix from cogeneration to chiller sales. • Service contract revenue rose by 11% to $2,217,758 for Q4 2018 compared to the same period in 2017. Installation revenue decreased by $368,166 to $1,747,094 for Q4 2018 compared to that of Q4 2017. • Fourth quarter 2018 energy production revenue was $1.6 million compared to $1.5 million for the same period in 2017, an increase of 10% year over year, illustrating the performance improvement of these sites. • Overall gross margin for Q4 2018 was 40% compared to 37% for the same period in 2017, an improvement of 8% year over year. 2
• Received largest order ever for $8.3 million turnkey trigeneration installation in Manhattan data center. The sale was financed through a third party ESCO. • Delivered 13 Tecochill systems to 7 different indoor cannabis growing facilities in 2018. • Granted ETL certification to ANSI/UL 1741 SA for smart inverters in August 2018. • Added a Florida service center to support the growing fleet in the Southeast portion of the United States. • Re-introduced Tecofrost gas engine ammonia refrigeration product line. Research and Development In 2018, Company expenses relating to R&D totaled $1.3 million for product development and improvement, product certifications, and patents. Key activities are summarized below. Product R&D: • Industrial Refrigeration Product Reintroduction (Tecofrost). Based on favorable and stable gas pricing, Tecogen is reintroducing an ammonia refrigeration line of natural gas compressors incorporating the Ultera emissions after-treatment system. Initial responses to Tecofrost have been very favorable. • Online Data Product Communication and Control. Development of a cloud-based remote communication system for our products, known as “CHP Insight,” continued throughout the year, and new features for data analysis and improved graphics have been added. • UL 1741SA Phase 1 Certification. This “smart” inverter certification, a requirement in California, was obtained for the InVerde e+. The certification requires inverters to be more tolerant of grid disturbances and capable of changing operation to assist the grid under certain conditions. • Battery Integration with InVerde e+. We have obtained a battery system for integration into the InVerde e+ inverter, and we expect to begin testing the system in 2019. Ultera Emissions R&D: • Forklift Truck Application of Ultera Emissions System. Following completion of the initial research funded by the Propane Education and Research Council, Mitsubishi Caterpillar Forklift of America has elected to work with Tecogen to refine the technology in preparation for full evaluation at its test facility. • Stationary Emissions Technologies. To date, Ultera is the only known technology that enables rich-burn engines to comply with the California South Coast Air Quality Management District (SCAQMD) Best Available Control Technology (BACT) Guideline for stationary non-emergency electrical generators powered by a spark-ignition internal combustion engine. Following successful operation of two Ultera kits sold several years ago, a public-sector customer in Southern California has opened discussions with Tecogen to retrofit additional engines with the Ultera system. Tecogen has provided quotes this month for Ultera systems in several large sizes and awaits feedback regarding next steps. • Ultera Automotive Catalyst Development. A leading US research and development organization is completing the first phase of a program to advance the Ultera technology in mobile applications and has identified a promising catalyst material to improve performance of the Ultera process. • Ultera Intellectual Property. We obtained two additional Ultera-related US patents, and our core Ultera patent was granted in the European Union. 3

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. 12
