Reading the filings

Arithmetic on what Clearthink 1 Acquisition Corp. 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.

  • Trading at a discount to trust

    At $9.93 the shares change hands 1.88% below the $10.12 they can be redeemed for. A holder buying here is paid that spread to carry deadline and redemption risk until the vote, and the trust keeps accreting underneath it.

  • Trust versus the $10 unit

    The trust holds $10.12 per public share, 1.2% above the $10.00 the units were sold at. That spread is accrued interest on the trust and, where the charter provides for it, sponsor contributions paid in to buy more time. It is the floor a public shareholder can redeem at, not a valuation of the business.

  • Time on the clock

    447 days to the Nov 25, 2027 deadline. The vehicle is early in its search window, and the deadline is not yet the binding constraint.

  • Underwriting

    D. Boral Capital led the offering. It has been named on 28 SPAC IPOs, book-running 27 of them. 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.

Potential is about execution, not about the target. It says nothing about whether the eventual deal is worth owning, because the target is usually unknown when the score is computed.

These are derived measures, not ratings of investment merit. They carry no view on the target, no price target and no recommendation, and a high score is not a reason to buy anything.

Clearthink 1 Acquisition Corp.: questions answered

What is Clearthink 1 Acquisition Corp. (CTAA)?

Clearthink 1 Acquisition Corp. is a special purpose acquisition company incorporated in Cayman Islands and registered with the SEC under CIK 0002094073. It completed its initial public offering in Feb 2026 and listing on Nasdaq. Class A shares trade under the ticker CTAA, units under CTAAU, rights under CTAAR on Nasdaq. The vehicle is sponsored by ClearThink through ClearThink 1 Sponsor LLC. The mandate targets financial services. IPO closed, trust funded, no definitive agreement announced.

How much does Clearthink 1 Acquisition Corp. hold in trust?

Approximately $126,658,210, or about $10.12 per public share, 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 Clearthink 1 Acquisition Corp. complete a merger?

By Nov 25, 2027. If no combination closes by then the sponsor must seek a further extension or wind the vehicle up and return the trust.

What happens if Clearthink 1 Acquisition Corp. 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 Clearthink 1 Acquisition Corp., 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, most recently disclosed at about $10.12 per share. 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.

What tickers does Clearthink 1 Acquisition Corp. trade under?

Class A shares trade as CTAA on Nasdaq, the units as CTAAU, with rights as CTAAR. Units trade first and separate into their component securities roughly 52 days after the IPO; only the Class A shares carry the redemption right against the trust.

Is the trust value the same as the share price for Clearthink 1 Acquisition Corp.?

No, and the gap between them is the whole trade. Trust per share is a disclosed, contractual figure of $10.12, being what a redeeming holder receives. The market price is whatever the shares change hands at: most recently $9.93, a discount of 1.88% to the redemption value. Quotes on this site are delayed and indicative; confirm on your own venue before trading.

How much dilution do Clearthink 1 Acquisition Corp.'s founder shares and warrants create?

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 Clearthink 1 Acquisition Corp., and what is their track record?

ClearThink 1 Sponsor LLC is the sponsor entity, part of the ClearThink franchise. This is the only vehicle we have attributed to that sponsor. Named principals: William Brock.

Which banks underwrote the Clearthink 1 Acquisition Corp. IPO?

D. Boral Capital, Dominari, Webull Financial. D. Boral Capital was credited as book-running manager on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.

Is Clearthink 1 Acquisition Corp. tradeable, and where?

Yes. CTAA returned a live quote of $9.93 on Nasdaq. Quotes here are delayed and refreshed on a schedule rather than streamed, so treat the figure as indicative and confirm on your own venue. Units and warrants trade under their own symbols and are quoted separately.

Is Clearthink 1 Acquisition Corp. a good investment?

That is not a question this site answers. Clearthink 1 Acquisition Corp. 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 Clearthink 1 Acquisition Corp. data come from?

Filings Clearthink 1 Acquisition Corp. submitted to the SEC under CIK 0002094073: 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.
