Tecogen Dissolves ULTRATEK Joint Venture

WALTHAM, MA--(Marketwired - October 26, 2017) - Tecogen® Inc. (TGEN), has announced that the company and its co-investors have agreed to dissolve their Ultra Emissions Technologies S.à r.l. ("ULTRATEK") joint venture. The dissolution process will take place under Luxembourg law and is expected to close by the end of this quarter. Once the process is complete, all unspent funds will be distributed to the ULTRATEK investors as agreed by a unanimous consent of the shareholders executed on October 24, 2017. As part of this disbursement, Tecogen will receive all its invested funds, $2 million in cash, and the sole exclusive IP that it licensed to ULTRATEK. Tecogen will then purchase all the non-cash assets of ULTRATEK, including all intellectual property, for $400,000. The IP includes two awarded patents, four patent applications, and all data and knowhow associated with the emissions testing performed by AVL.

John Hatsopoulos, Tecogen Co-CEO, stated, "As discussed on last week's investor conference call, unwinding ULTRATEK is the right move strategically for the company for several reasons. Firstly, we will add $1.6 million to our balance sheet, which the company can apply to its growing core business. Secondly, we will gain the complete rights and control of the ULTRATEK technology following the successful completion of 18 months of intense research that successfully demonstrated the effectiveness of the process while establishing an impressive IP portfolio. This puts us in a strong position from which we can restructure the research and development business entity and raise funds to carry the technology forward to commercialization."

"The rigorous testing completed by ULTRATEK resulted in unassailable documentation and proof of the effectiveness of the Ultera process in reducing criteria emissions from gasoline-powered vehicles with no loss of performance or fuel economy," said Robert Panora, Tecogen President and COO. "Our engagement with both regulators and leading industry manufacturers has provided us with strategic insight regarding the path we should take to gain the confidence of the automotive industry that we possess a practical solution to a difficult problem, one that will neither be resolved in the near or medium term by electrification nor tolerated by the public and regulators. We very much look forward to taking this exciting technology to the next level."
