Subsequent Events [Abstract] |
Subsequent Events | Subsequent Events We have evaluated events through the date of this filing, and, except as described below, have determined that no material subsequent events occurred that would require recognition in the consolidated financial statements or disclosure in the notes thereto for the period ended December 31, 2024. Settlement of Litigation Regarding Fire at Milton Sports Centre On January 13, 2025, Tecogen and our insurers entered into a Settlement Agreement and Full and Final Release from any and all claims, obligations and liabilities, arising from the July 10, 2022 fire with the plaintiff's in the amount of CDN $400,000, of which we are responsible for CDN $100,000. On February 7, 2025, we remitted CDN $100,000, or $70,994, representing payment in full of our liability. We will recognize a benefit of $79,006 in our consolidated financial statements in the first quarter of fiscal 2025. Vertiv Sales and Marketing Agreement - Data Center Cooling Market On February 28, 2025, we entered into a Sales and Marketing Agreement with Vertiv Corporation (“Vertiv”) relating to sales of Tecogen DTx chillers for data center cooling applications (the “Vertiv Agreement”). The Vertiv Agreement has a term of two years and provides that Vertiv will establish a budget for marketing activities and use commercially reasonable efforts to sell our DTx chillers for cooling applications in data centers. The Vertiv Agreement also provides the basis for the negotiation of a definitive supply agreement between us and Vertiv. We have agreed to provide Vertiv with reasonable discounts for purchases of significant volumes of our chillers, and Vertiv has agreed to use commercially reasonable efforts to assist us in securing favorable terms for engineering components and supplies for manufacturing our chillers. Pursuant to the Vertiv Agreement we have granted Vertiv the exclusive right to market and sell our DTx chillers for data center cooling applications outside the United States, and the non-exclusive right to market and sell our DTx chillers within the United States. We have also agreed to grant Vertiv the exclusive right to market and sell our DTx chillers for data center cooling applications in the United States if Vertiv achieves and maintains agreed sales levels of DTx chillers. The foregoing description of the Vertiv Agreement is not complete and is qualified in its entirety by reference to the full text thereof, a copy of which is filed as Exhibit 99.01 to our Current Report on Form 8-K filed with the Securities and Exchange Commission on February 28, 2025, and incorporated by reference as Exhibit 10.30 hereto. Related Party Notes On January 14, 2025 we agreed to permit Mr. Lewis to either receive repayment of his note in cash or, at his discretion, convert the balance of the promissory note into shares of our common stock. On February 18, 2025 we amended the promissory notes with Mr. Hatsopoulos to extend the maturity dates for both promissory notes to July 31, 2026. We also agreed to permit Mr. Hatsopoulos to either receive repayment of his notes in cash, or at his discretion, convert the balance(s) due of one or both of the promissory notes into shares of our common stock. In the event of such a conversion by Mr. Hatsopoulos or Mr. Lewis, the number of shares we will be required to issue will be determined by dividing the balance(s) due under the promissory note(s) by the average closing price per share of our shares during the thirty-day period prior to the date of conversion.
