First Reserve Sustainable Growth Corp. (FRSGW) operates as a blank check company whose sole purpose is to effect a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination with one or more businesses focused on solutions, processes, and technologies that facilitate the energy transition toward a low- or no-carbon emitting future; it conducts no significant operations and generates no revenue. Founded in 2021 and headquartered in Stamford, Connecticut, with additional presence in Houston, Texas, the company targets opportunities in the sustainable energy and infrastructure sectors, including electric vehicle infrastructure, renewable energy services, and related industrial end-markets; its sponsor, First Reserve, a private equity firm established in 1983, provides expertise across energy value chains. In March 2023, the company redeemed all outstanding Class A common shares at approximately $10.16 per share and liquidated following the failure to complete an initial business combination by the extended deadline, after mutually terminating a $675 million proposed merger with UK-based EV fleet charging provider EO Charging (Juuce Limited) in March 2022 due to market conditions; warrants (FRSGW) continue to trade on Nasdaq post-liquidation with no subsequent merger announcements as of late 2025.
