Reading the filings
Arithmetic on what StoneBridge Acquisition II 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
209 days to the Apr 1, 2027 deadline. Still workable for a deal already in diligence, tight for one that has not been found. Watch for an extension proxy, which typically appears a month or two before the date.
Underwriting
Maxim Group led the offering. It has been named on 31 SPAC IPOs, book-running 23 of them, and 28.6% 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.

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

searching
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.

StoneBridge Acquisition II Corp: questions answered
What is StoneBridge Acquisition II Corp (APAC)?
StoneBridge Acquisition II Corp is a special purpose acquisition company incorporated and registered with the SEC under CIK 0002043630. It completed its initial public offering in Oct 2025, raising $57.5M in gross proceeds and listing on Nasdaq. Class A shares trade under the ticker APAC, units under APACU, rights under APACR on Nasdaq. The vehicle is sponsored by StoneBridge through StoneBridge Acquisition Sponsor II LLC. The mandate targets generalist. IPO closed, trust funded, no definitive agreement announced.
How much does StoneBridge Acquisition II Corp hold in trust?
Approximately $59,077,144, 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 StoneBridge Acquisition II Corp complete a merger?
By Apr 1, 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 StoneBridge Acquisition II 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 StoneBridge Acquisition II 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 StoneBridge Acquisition II Corp trade under?
Class A shares trade as APAC on Nasdaq, the units as APACU, with rights as APACR. 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 StoneBridge Acquisition II 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 StoneBridge Acquisition II 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 StoneBridge Acquisition II Corp, and what is their track record?
StoneBridge Acquisition Sponsor II LLC is the sponsor entity, part of the StoneBridge franchise. This is the only vehicle we have attributed to that sponsor. Named principals: Bhargav Marepally.
Which banks underwrote the StoneBridge Acquisition II 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 StoneBridge Acquisition II Corp tradeable, and where?
Yes. APAC returned a live quote of $10.28 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 StoneBridge Acquisition II Corp a good investment?
That is not a question this site answers. StoneBridge Acquisition II 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 StoneBridge Acquisition II Corp data come from?
Filings StoneBridge Acquisition II Corp submitted to the SEC under CIK 0002043630: 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.
