Reading the filings
Arithmetic on what Disc Medicine, 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 $10.00 per public share, effectively the $10.00 the units were sold at, so little or no interest has accrued to the account yet.
Sponsor record
FS Development has launched 2 vehicles. Of the 2 that have resolved, 2 closed a combination and 0 liquidated, a 100% completion rate. A sponsor's record is not a forecast, but it does tell you whether the team has taken a deal across the line before.
Underwriting
Jefferies led the offering. It has been named on 73 SPAC IPOs, book-running 68 of them, and 53.1% 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.
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.
763 filings in all. 31 in the last three months, against a busiest month of 51.

Disc Medicine, Inc.: questions answered
What is Disc Medicine, Inc. (IRON)?
Disc Medicine, Inc. is a special purpose acquisition company incorporated and registered with the SEC under CIK 0001816736. It completed its initial public offering in Aug 2020, raising $121M in gross proceeds and listing on Nasdaq. Class A shares trade under the ticker IRON on Nasdaq. The vehicle is sponsored by FS Development through FS Development Holdings, LLC. The mandate targets healthcare. Business combination closed; the company trades under a new ticker.
How much does Disc Medicine, Inc. hold in trust?
Approximately $120,754,533, 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 Disc Medicine, Inc. 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 Disc Medicine, 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 Disc Medicine, 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 $10.00 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 Disc Medicine, Inc. trade under?
Class A shares trade as IRON on Nasdaq. 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 Disc Medicine, Inc.?
No, and the gap between them is the whole trade. Trust per share is a disclosed, contractual figure of $10.00, being what a redeeming holder receives. The market price is whatever the shares change hands at: most recently $79.42, a spread to the redemption value. Quotes on this site are delayed and indicative; confirm on your own venue before trading.
Who sponsors Disc Medicine, Inc., and what is their track record?
FS Development Holdings, LLC is the sponsor entity, part of the FS Development franchise. That franchise has launched 2 vehicles in total, of which 2 closed a combination and 0 liquidated, a 100% completion rate on resolved vehicles.
Which banks underwrote the Disc Medicine, Inc. IPO?
Jefferies. Jefferies was credited as book-running manager on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.
Is Disc Medicine, Inc. tradeable, and where?
Yes. IRON returned a live quote of $79.42 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 Disc Medicine, Inc. a good investment?
That is not a question this site answers. Disc Medicine, 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 Disc Medicine, Inc. data come from?
Filings Disc Medicine, Inc. submitted to the SEC under CIK 0001816736: 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 20, 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.
