Reading the filings
Arithmetic on what ACP Holdings 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.
Time on the clock
353 days to the Oct 7, 2027 deadline. The vehicle is early in its search window, and the deadline is not yet the binding constraint.
Warrant coverage
Each unit carried one-half 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.
Underwriting
Roth Capital Partners led the offering. It has been named on 12 SPAC IPOs, book-running 10 of them, and 66.7% 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.
From listing to the date ACP Holdings Acquisition Corp. must close a deal, extend again, or return the trust. The marker is today.
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.
43 filings in all. 16 in the last three months, against a busiest month of 15.

Attention is not quality. FOMO rises on news volume and on the market paying above trust, both of which have preceded plenty of disappointments.

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.
News on ACP Holdings Acquisition Corp.
Last 90 daysNothing in the last 90 days that names this vehicle. We attribute a story only when the release carries the ticker or the registered name, so an empty section means no press release or wire story matched — not that nothing was published.

ACP Holdings Acquisition Corp.: questions answered
What is ACP Holdings Acquisition Corp. (ACGC)?
ACP Holdings Acquisition Corp. is a special purpose acquisition company incorporated and registered with the SEC under CIK 0002111542. It completed its initial public offering in Apr 2026 and listing on Nasdaq. Class A shares trade under the ticker ACGC, units under ACGCU, warrants under ACGCW on Nasdaq. The vehicle is sponsored by Union Street through Union Street Sponsor, LLC. The mandate targets generalist. Definitive business-combination agreement signed, closing pending.
How much does ACP Holdings Acquisition Corp. hold in trust?
Approximately $217,381,636, 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 ACP Holdings Acquisition Corp. complete a merger?
By Oct 7, 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 ACP Holdings 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 ACP Holdings 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.
What tickers does ACP Holdings Acquisition Corp. trade under?
Class A shares trade as ACGC on Nasdaq, the units as ACGCU, and the warrants as ACGCW. 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 ACP Holdings 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.
How much dilution do ACP Holdings Acquisition Corp.'s founder shares and warrants create?
Each unit also carried one-half 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 ACP Holdings Acquisition Corp., and what is their track record?
Union Street Sponsor, LLC is the sponsor entity, part of the Union Street franchise. This is the only vehicle we have attributed to that sponsor. Named principals: Andrew Mallozzi.
Which banks underwrote the ACP Holdings Acquisition Corp. IPO?
Roth Capital Partners. Roth Capital Partners was credited as book-running manager on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is ACP Holdings Acquisition Corp. tradeable, and where?
Yes. ACGC returned a live quote of $10.07 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 ACP Holdings Acquisition Corp. a good investment?
That is not a question this site answers. ACP Holdings 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 ACP Holdings Acquisition Corp. data come from?
Filings ACP Holdings Acquisition Corp. submitted to the SEC under CIK 0002111542: 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.
