New Cash, New Options, Same Thesis

In a post earlier this month (“Finding Alpha on X”) I mentioned why Tecogen’s (TGEN 0.00%↑) gas‑engine chillers could become a surprise beneficiary of the AI datacenter build‑out.

Finding Alpha On X

Since then two meaningful updates have landed:


1. Capital Raise @ $5.00

  • 3.5 million shares (plus full 485 k over‑allotment) sold on 18 July at $5.00.

  • ≈ $19.9 million gross proceeds closed 21 July.

  • Management earmarked use of funds for working capital, product development, and — explicitly — expansion into the data‑center market.

Bottom line: the raise extends runway well into 2026, easing “going‑concern” fears for potential customers who need multiyear service support.


2. Options Finally Listed

As of last Friday TGEN has a chain out to January 2026. Liquidity is thin but workable, which lets us monetize patience instead of chasing spot.


Quick Thesis Refresher

  • AI’s heat dilemma: GPU racks now swallow 50‑70 kW; electric chillers compete for the same power budget.

  • Gas‑engine chillers (Distributed Thermal Exchange): Off‑grid cooling plus optional cogeneration = lower operating cost and resilience during peak‑pricing events—think ERCOT (Electric Reliability Council of Texas) summer afternoons).

  • “First logo” domino: One 20‑unit datacenter order would roughly double annual revenue and validate the tech across the sector.

  • Credibility de‑risked: Vertiv partnership + NYSE uplist were big steps; this fresh equity raise tackles the remaining balance‑sheet worry.

With options trading, we have a new way to add exposure to this name, while using its volatility to our advantage.

Details below.
