First Reserve Sustainable Growth Corp. (FRSGU) operates as a blank check company focused on effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses in the energy transition sector; it targets opportunities and companies that provide solutions, processes and technologies facilitating, improving or complementing the shift toward a low- or no-carbon emitting future. Formed in 2021 and headquartered in Stamford, Connecticut, the company has no current operating businesses or revenue generation. Its sponsor, affiliates of First Reserve, a global private equity firm with over 40 years of experience investing across the energy system, provides strategic expertise in infrastructure solutions, value-added infrastructure and resources.
The company previously pursued a business combination with Juuce Limited (trading as EO Charging), a UK-based provider of technology-enabled turnkey solutions for electric vehicle fleets including charging infrastructure, software and services for commercial and governmental operators; the transaction, announced in 2021 with a pro-forma enterprise value of $675 million, was mutually terminated in March 2022 due to market conditions. In March 2023, FRSG announced the redemption of all outstanding public shares at approximately $10.16 per share and proceeded to liquidate after failing to complete an initial business combination within the required timeframe under its charter. No subsequent mergers, acquisitions, funding rounds or operational activities have been reported as of late 2025, with the entity in a liquidated state and shares no longer actively trading.
