Reading the filings
Arithmetic on what Plum 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.
Trust versus the $10 unit
The trust holds $10.00 per public share, effectively the $10.00 the units were sold at, so little or no interest has accrued to the account yet.
Warrant coverage
Each unit carried one-third of one 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
Citigroup led the offering. It has been named on 123 SPAC IPOs, book-running 87 of them, and 12.4% 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.

Plum Acquisition Corp. III: questions answered
What is Plum Acquisition Corp. III (PLMJF)?
Plum Acquisition Corp. III is a special purpose acquisition company incorporated in British Columbia, Canada and registered with the SEC under CIK 0001845550. It completed its initial public offering in Jul 2021, raising $278.0M in gross proceeds and listing on OTC. Class A shares trade under the ticker PLMJF on OTC. The vehicle is sponsored by Alpha Partners Technology Merger through Alpha Partners Technology Merger Sponsor LLC. Deadline lapsed without a deal; trust returned to public shareholders.
How much does Plum Acquisition Corp. III hold in trust?
Approximately $497,828, or about $10.00 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 Plum 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 Plum 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 Plum 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, most recently disclosed at about $10.00 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 Plum Acquisition Corp. III trade under?
Class A shares trade as PLMJF on OTC. 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 Plum 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 Plum Acquisition Corp. III's founder shares and warrants create?
Each unit also carried one-third of one 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 Plum Acquisition Corp. III, and what is their track record?
Alpha Partners Technology Merger Sponsor LLC is the sponsor entity, part of the Alpha Partners Technology Merger franchise. This is the only vehicle we have attributed to that sponsor.
Which banks underwrote the Plum Acquisition Corp. III IPO?
Citigroup, Morgan Stanley, William Blair. Citigroup and Morgan Stanley were credited as book-running managers on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is Plum Acquisition Corp. III a good investment?
That is not a question this site answers. Plum 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 Plum Acquisition Corp. III data come from?
Filings Plum Acquisition Corp. III submitted to the SEC under CIK 0001845550: 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

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.
