TortoiseEcofin Acquisition Corp. III WT (NYSE: TRTL-WT) represents the publicly traded warrants of TortoiseEcofin Acquisition Corp. III, a blank check company incorporated in the Cayman Islands in 2021 and headquartered in Zephyr Cove, Nevada; the underlying company focuses on effecting mergers, share exchanges, asset acquisitions, share purchases, reorganizations, or similar business combinations with one or more businesses in the energy transition and sustainability sectors, including energy decarbonization solutions, climate technology, real estate technology, and related industries requiring innovative emissions reduction technologies. Warrants entitle holders to purchase Class A ordinary shares at an exercise price of $11.50 per whole warrant, originally issued as part of units in the company's July 2021 initial public offering that raised $345 million. The company conducts no independent operations and generates no revenues, relying on its trust account for funding while seeking targets primarily in North America.
In September 2023, TortoiseEcofin Acquisition Corp. III announced a definitive business combination agreement with One Energy Enterprises Inc., a U.S.-based provider of behind-the-meter megawatt-scale wind energy systems and industrial power solutions, valued at a pre-money enterprise value of $300 million for One Energy; the deal, amended February 2024, envisioned renaming the post-combination entity One Power Company and listing on the NYSE under ticker ONE, with an S-4 registration statement filed in May 2024. However, One Energy unilaterally terminated the agreement in July 2024, prompting NYSE delisting proceedings in July 2024 for failure to complete a business combination within three years and a board decision in August 2024 to liquidate the trust account, redeeming Class A shares around September 6, 2024, after settling taxes and costs; the company settled with One Energy on August 29, 2024, confirming termination, filed a Form 15 to end reporting, and shifted to OTC trading (TRTUF) with no plans for alternative targets.
