TortoiseEcofin Acquisition Corp. III: questions answered

What is TortoiseEcofin Acquisition Corp. III?

TortoiseEcofin Acquisition Corp. III is a special purpose acquisition company incorporated and registered with the SEC under CIK 0001847112. It completed its initial public offering in Jul 2021, raising $345.0M in gross proceeds. The vehicle is sponsored by TortoiseEcofin through TortoiseEcofin Sponsor III LLC. The mandate targets energy transition. Deadline lapsed without a deal; trust returned to public shareholders.

How much does TortoiseEcofin Acquisition Corp. III hold in trust?

Approximately $170,164,951, as at the most recent filing on record. Trust balances move: shareholders redeem at extension votes and at the combination vote, and sponsors pay contributions in to extend. Treat the figure as a point-in-time disclosure, not a running balance.

When must TortoiseEcofin Acquisition Corp. III complete a merger?

No combination deadline appears in the filings we have indexed. The date is stated in the charter and repeated in each quarterly report; where our parser could not establish it with confidence we leave it blank rather than infer one.

What happens if TortoiseEcofin Acquisition Corp. III does not find a target in time?

The charter requires the vehicle to redeem 100% of the public shares and return the trust, pro rata, to public shareholders. That is the mechanism working as designed rather than a default. Founder shares and warrants are worthless in that outcome, which is why the sponsor's incentive is to get a deal done or to buy more time. Across the market, deadline lapsed without a deal; trust returned to public shareholders.

Can I redeem shares in TortoiseEcofin Acquisition Corp. III, and at what price?

Public shareholders may elect to redeem in connection with a combination vote and at each extension vote, at the pro-rata trust value on the relevant record date. Redemption is a right attached to the public shares only; warrants and rights carry no claim on the trust. The mechanics and the deadline for electing are set out in the proxy statement for the vote in question.

Is the trust value the same as the share price for TortoiseEcofin Acquisition Corp. III?

No. Trust per share is a disclosed, contractual figure: what a redeeming holder receives. The market price is whatever the shares change hands at, which can sit above the trust when a deal is well received or below it when the market doubts one will close. We do not have a current quote for this vehicle, so no spread is shown.

Who sponsors TortoiseEcofin Acquisition Corp. III, and what is their track record?

TortoiseEcofin Sponsor III LLC is the sponsor entity, part of the TortoiseEcofin franchise. This is the only vehicle we have attributed to that sponsor. Named principals: Arc Logistics.

Is TortoiseEcofin Acquisition Corp. III a good investment?

That is not a question this site answers. TortoiseEcofin Acquisition Corp. III is covered here as reference data: what the company filed, when it filed it, and what the numbers in those filings say. The Edge, FOMO and Potential scores on this page are derived measures with a published formula, not ratings of investment merit: they describe the setup, and every component is shown so you can take them apart. We publish no price targets and no recommendations, and nothing here should be read as advice. The figures are a starting point for your own work, and each one carries the accession number of the filing it came from.

Where does this TortoiseEcofin Acquisition Corp. III data come from?

Filings TortoiseEcofin Acquisition Corp. III submitted to the SEC under CIK 0001847112: the registration statement and final prospectus for the structure, quarterly and annual reports for the trust, current reports and proxy statements for deals, votes and extensions. Trust economics are taken from the registrant's own XBRL tags rather than parsed from prose, which is why they are exact. Every filing in the history above is listed with its accession number, which identifies the document uniquely on EDGAR; Pro accounts open it directly from the row.

Compiled by the SPACListing research desk

Last reconciled Sep 4, 2026

Every figure on this page is read from documents the registrants filed with the U.S. Securities and Exchange Commission, principally the IPO prospectus (Form 424B4), quarterly and annual reports, current reports and proxy statements, the registrant's own XBRL tags for trust economics. Nothing is sourced from press coverage, from the companies themselves, or from a third-party aggregator. Where a filing does not disclose something, the field is left blank rather than estimated.
