Overview
Altimar Acquisition Corp. III is a special purpose acquisition company incorporated in Cayman Islands and registered with the SEC under CIK 0001841004. It completed its initial public offering in Mar 2021. The vehicle is sponsored by Altimar through Altimar Sponsor III, LLC. The mandate targets generalist. Deadline lapsed without a deal; trust returned to public shareholders.
“we intend to focus on two characteristics as a common theme: a strong organic growth plan coupled with a compelling business model that is materially cash generative at maturity.”
Reading the filings
Arithmetic on what Altimar Acquisition Corp. III has disclosed, written the way a desk would read it. These are observations, not a rating. Nothing here scores the vehicle or implies a view on it.
Extension history
Shareholders have already approved 3 extensions. Each one opened a redemption window, so the public float and the trust are almost certainly smaller than at IPO, and each typically came with a sponsor contribution that lifts trust per share. A vehicle on its second or third extension is one where the sponsor is paying to keep the search alive.
Warrant coverage
Each unit carried one-fourth warrant per unit. Warrants are dilution deferred: they cost the holder nothing until exercised, and they overhang the post-combination share count. Thinner coverage is generally a sign of a stronger book at pricing.
Sponsor record
Altimar has launched 3 vehicles. Of the 3 that have resolved, 2 closed a combination and 1 liquidated, a 66.7% completion rate. A sponsor's record is not a forecast, but it does tell you whether the team has taken a deal across the line before.
Underwriting
Goldman Sachs led the offering. It has been named on 97 SPAC IPOs, book-running 59 of them, and 58.3% of its resolved vehicles closed a deal. The syndicate has no control over whether a sponsor finds a target, but the quality of the book at pricing shapes who ends up holding the units.
Filings per month since the first one. A vehicle that has gone quiet with a deadline ahead is a different proposition from one that is still working.

Altimar Acquisition Corp. III: questions answered
What is Altimar Acquisition Corp. III?
Altimar Acquisition Corp. III is a special purpose acquisition company incorporated in Cayman Islands and registered with the SEC under CIK 0001841004. It completed its initial public offering in Mar 2021. The vehicle is sponsored by Altimar through Altimar Sponsor III, LLC. The mandate targets generalist. Deadline lapsed without a deal; trust returned to public shareholders.
How much does Altimar Acquisition Corp. III hold in trust?
Approximately $157,023,966, 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 Altimar 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 Altimar 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 Altimar 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 Altimar 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.
How much dilution do Altimar Acquisition Corp. III's founder shares and warrants create?
Each unit also carried one-fourth warrant per unit, which is dilution deferred until exercise. Both are disclosed in the prospectus and both survive into the combined company, which is why a de-SPAC at $10 is not economically the same as an IPO at $10.
Who sponsors Altimar Acquisition Corp. III, and what is their track record?
Altimar Sponsor III, LLC is the sponsor entity, part of the Altimar franchise. That franchise has launched 3 vehicles in total, of which 2 closed a combination and 1 liquidated, a 66.7% completion rate on resolved vehicles. Named principals: Tom Wasserman.
Which banks underwrote the Altimar Acquisition Corp. III IPO?
Goldman Sachs, J.P. Morgan. Goldman Sachs and J.P. Morgan were credited as book-running managers on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is Altimar Acquisition Corp. III a good investment?
That is not a question this site answers. Altimar 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 Altimar Acquisition Corp. III data come from?
Filings Altimar Acquisition Corp. III submitted to the SEC under CIK 0001841004: 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.

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.
