Overview
Aetherium Acquisition Corp is a special purpose acquisition company incorporated in Delaware and registered with the SEC under CIK 0001866547. It completed its initial public offering in Jan 2022. The vehicle is sponsored by Aetherium through Aetherium Capital Holdings LLC. The mandate targets technology. Definitive business-combination agreement signed, closing pending.
“we intend to focus on businesses in the education, training and education technology ("EdTech") industries, specifically in Asia (excluding China).”
Reading the filings
Arithmetic on what Aetherium 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.
Trust versus the $10 unit
The trust holds $10.25 per public share, 2.5% 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.
Extension history
Shareholders have already approved 3 extensions. 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.
Warrant coverage
Each unit carried 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
US Tiger Securities led the offering. It has been named on 14 SPAC IPOs, book-running 2 of them, and 45.5% 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.
At every shareholder vote holders may hand their shares back for their cash. Each bar is one vote, read out of the 8-K that reported it.
3.1M shares handed back across 2 votes, 27% of the shares sold at IPO.
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.

Scores
Recomputed 2d agoThree readings of Aetherium Acquisition Corp, each an unweighted mean of the components shown beneath it, and each component a percentile against every live SPAC rather than an absolute we invented. They describe the setup, not the merit. How they are built

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 Aetherium 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.

Aetherium Acquisition Corp: questions answered
What is Aetherium Acquisition Corp?
Aetherium Acquisition Corp is a special purpose acquisition company incorporated in Delaware and registered with the SEC under CIK 0001866547. It completed its initial public offering in Jan 2022. The vehicle is sponsored by Aetherium through Aetherium Capital Holdings LLC. The mandate targets technology. Definitive business-combination agreement signed, closing pending.
How much does Aetherium Acquisition Corp hold in trust?
Approximately $19,558,236, or about $10.25 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 Aetherium 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 Aetherium 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 Aetherium 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 $10.25 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.
Is the trust value the same as the share price for Aetherium 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 Aetherium Acquisition Corp's founder shares and warrants create?
Each unit also carried 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 Aetherium Acquisition Corp, and what is their track record?
Aetherium Capital Holdings LLC is the sponsor entity, part of the Aetherium franchise. This is the only vehicle we have attributed to that sponsor. Named principals: Jonathan Chan.
Which banks underwrote the Aetherium Acquisition Corp IPO?
US Tiger Securities, Tiger Brokers (NZ), Joseph Gunnar &. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is Aetherium Acquisition Corp a good investment?
That is not a question this site answers. Aetherium 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 Aetherium Acquisition Corp data come from?
Filings Aetherium Acquisition Corp submitted to the SEC under CIK 0001866547: 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.
