Reading the filings

Arithmetic on what Allegro Merger 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 $10.30 per public share, 3.0% 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.

  • Underwriting

    Cantor Fitzgerald led the offering. It has been named on 114 SPAC IPOs, book-running 101 of them, and 21.4% 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.

Allegro Merger Corp.: questions answered

What is Allegro Merger Corp.?

Allegro Merger Corp. is a special purpose acquisition company incorporated in Delaware and registered with the SEC under CIK 0001720025. It completed its initial public offering in Jul 2018, raising $149.5M in gross proceeds. The vehicle is sponsored by Allegro Merger. Deadline lapsed without a deal; trust returned to public shareholders.

How much does Allegro Merger Corp. hold in trust?

Approximately $115,232,882, or about $10.30 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 Allegro Merger 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 Allegro Merger 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 Allegro Merger 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 $10.30 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 Allegro Merger 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.

Who sponsors Allegro Merger Corp., and what is their track record?

Allegro Merger is the sponsor entity, part of the Allegro Merger franchise. This is the only vehicle we have attributed to that sponsor. Named principals: Eric S. Rosenfeld.

Which banks underwrote the Allegro Merger Corp. IPO?

Cantor Fitzgerald, Chardan, I-Bankers Securities. Cantor Fitzgerald and Chardan and I-Bankers Securities were credited as book-running managers on the cover. Syndicate membership and role are read from the prospectus cover and the underwriting section.

Is Allegro Merger Corp. a good investment?

That is not a question this site answers. Allegro Merger 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 Allegro Merger Corp. data come from?

Filings Allegro Merger Corp. submitted to the SEC under CIK 0001720025: 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.
