Reading the filings
Arithmetic on what ONE Nuclear Energy Inc. 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 $10.75 per public share, 7.5% 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.
From listing to the date ONE Nuclear Energy Inc. 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.
115 filings in all. 35 in the last three months, against a busiest month of 25.

ONE Nuclear Energy Inc.: questions answered
What is ONE Nuclear Energy Inc. (HVII)?
ONE Nuclear Energy Inc. is a special purpose acquisition company incorporated and registered with the SEC under CIK 0001846416. It completed its initial public offering in Jan 2025, raising $186M in gross proceeds and listing on Nasdaq. Class A shares trade under the ticker HVII, units under HVIIU, rights under HVIIR on Nasdaq. The mandate targets technology, energy transition, industrials. Deadline lapsed without a deal; trust returned to public shareholders.
How much does ONE Nuclear Energy Inc. hold in trust?
Approximately $200,141,138, or about $10.75 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 ONE Nuclear Energy Inc. complete a merger?
By Jan 21, 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 ONE Nuclear Energy Inc. 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 ONE Nuclear Energy Inc., 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 $10.75 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 ONE Nuclear Energy Inc. trade under?
Class A shares trade as HVII on Nasdaq, the units as HVIIU, with rights as HVIIR. 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 ONE Nuclear Energy Inc.?
No, and the gap between them is the whole trade. Trust per share is a disclosed, contractual figure of $10.75, being what a redeeming holder receives. The market price is whatever the shares change hands at: most recently $4.46, a spread to the redemption value. Quotes on this site are delayed and indicative; confirm on your own venue before trading.
Is ONE Nuclear Energy Inc. tradeable, and where?
Yes. HVII returned a live quote of $4.46 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 ONE Nuclear Energy Inc. a good investment?
That is not a question this site answers. ONE Nuclear Energy Inc. 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 ONE Nuclear Energy Inc. data come from?
Filings ONE Nuclear Energy Inc. submitted to the SEC under CIK 0001846416: 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 23, 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.
