Reading the filings
Arithmetic on what Mars 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.
Extension history
Shareholders have already approved 1 extension. 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.
Underwriting
Maxim Group led the offering. It has been named on 38 SPAC IPOs, book-running 26 of them, and 63% 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.

Mars Acquisition Corp.: questions answered
What is Mars Acquisition Corp.?
Mars Acquisition Corp. is a special purpose acquisition company incorporated in Cayman Islands and registered with the SEC under CIK 0001892922. It completed its initial public offering in Feb 2023. The vehicle is sponsored by Mars through Mars Capital Holding Corporation. The mandate targets technology, healthcare, industrials. Business combination closed; the company trades under a new ticker.
How much does Mars Acquisition Corp. hold in trust?
Approximately $22,836,871, 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 Mars Acquisition Corp. 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 Mars 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 Mars 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. 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 Mars Acquisition Corp.?
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 Mars Acquisition Corp., and what is their track record?
Mars Capital Holding Corporation is the sponsor entity, part of the Mars franchise. This is the only vehicle we have attributed to that sponsor. Named principals: Karl Brenza.
Which banks underwrote the Mars Acquisition Corp. IPO?
Maxim Group. Maxim Group was credited as book-running manager on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is Mars Acquisition Corp. a good investment?
That is not a question this site answers. Mars 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 Mars Acquisition Corp. data come from?
Filings Mars Acquisition Corp. submitted to the SEC under CIK 0001892922: 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 Oct 19, 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.
