SpacBrain’s read

Trust settled

The deal closed — SPAC shares became the target's shares, so there is no trust left to redeem (nobody missed a window; holders who wanted cash elected it at the vote).


In plain terms

What it is
A SPAC from Horizon Space Acquisition II Sponsor Corp., listed on Nasdaq in November 2024.
What it's doing now
It agreed in January 2026 to buy SL BIO Ltd., a biopharmaceutical company company. The deal valued that business at about $5.57B. That purchase completed, and it stopped being a SPAC — the shares became shares in the business it bought.
What you should know
This SPAC has finished. The purchase completed, and the shares became shares in the company it bought — anyone who wanted the cash instead asked for it at the vote, so there is no cash left here to claim and no deadline left to miss.

Nothing dated is on file. That is an absence in the record, not a statement that nothing is coming.

Yield to redemption

Nothing left to redeem — no yield to compute.

This SPAC has finished — its trust was paid back or used to close the deal, so there is nothing left to redeem and no yield to compute. A yield to redemption is a claim that you can hand these shares back for the trust cash. That account is closed, so this page will not print a number here.


What happened to the cash

The reasoning behind the verdict above, in the order the filings establish it.

  1. The deal closed — SPAC shares became the target's shares, so there is no trust left to redeem (nobody missed a window; holders who wanted cash elected it at the vote).

1 filed event

Each time shareholders were offered their cash back, some took it. Heavy cash-outs drain the account and shrink the number of shares left — whatever remains has to carry the deal.

The score

deterministic, from filed fields

HSPT is not in the scored universe, so no score is shown. A withheld score is a fact about the record, not a verdict about the company.

Asymmetric return scoreNeither a price nor a cash-per-share figure is on file for this vehicle, and the score is a ratio between the two. Nothing is estimated to fill the gap.

The score is only published for names that carry both a price and a filed cash-per-share figure — 292 of the tracked fleet today. The rest keep an empty dial rather than a modelled one, and fill in by themselves as the fields land.

The company

from SEC filings
Read the full profile

Horizon Space Acquisition II Corp. (Nasdaq: HSPT) is a blank-check company whose IPO was priced on November 15, 2024, per a 424B prospectus filed under accession number 0001929980-24-000553, with each unit representing an interest in a trust at $10.53 per unit. The company's common ticker HSPT appears on the cover page of a 10-Q filed on May 20, 2026, under accession number 0001929980-26-000230. The vehicle completed a business combination and no longer files, with its closed status established by Form 25 filed on June 12, 2026, under accession number 0001354457-26-000570, pursuant to 17 CFR 240.12d2-2(a)(3), reflecting that its Ordinary Shares, Rights, and Units came to evidence other securities in substitution therefor.


Material findings

from the full read of every filing

Every document this company files gets read whole — body and exhibits. These are the ones the read flagged as material, newest first, each citing its filing.

  • The extension structure is unusually favourable to the sponsor: the fee is capped at the lesser of $50,000 or $0.033 per share, so if redemptions shrink the float the total cost falls while the per-share accretion stays minimal. Holders trade twelve more months of deal risk for roughly three cents a month. The proposals are cross-conditioned, so a failure on either forces the February 18, 2026 wind-up and full redemption at trust.

  • A prospectus for up to 567,018,150 PubCo shares against a SPAC whose public float is a small fraction of that shows how little of the combined company legacy HSPT holders will own - the target's shareholders take the overwhelming majority. Redemption at the trust value, calculated two business days before the meeting, is the last chance to take cash instead. Sponsor working capital loans convert at $10.00, above the likely post-deal trading level.

  • 567,018,150 ordinary shares is the ceiling on what PubCo may issue in the two-step merger, and this is the first version of the registration statement to state it, so it is the first from which an HSPT holder can size the dilution. Immediately before the First Merger each Acquiror Unit separates into one ordinary share and one right, and each Acquiror Right converts into one-tenth (1/10) of an Acquiror Ordinary Share, so a unit holder's outcome depends on that separation as well as on the merger itself. PubCo shares have a par value of $0.0001 and are expected to list on Nasdaq.

  • This first version leaves the central number blank — the cover registers up to [ ] ordinary shares and no registration number has been assigned yet — so the dilution an HSPT holder faces cannot be read from this filing at all. What is stated is the unit mechanics: immediately before the First Merger each Acquiror Unit separates into one ordinary share and one right, and each Acquiror Right converts into one-tenth (1/10) of an Acquiror Ordinary Share. PubCo expects the ordinary shares to be listed and traded on Nasdaq following the consummation.

In plain English

tap a term to open it

Every piece of jargon this page could have used, and what it actually means.

Open the plain-English guide
No floor / floorlessthe cash guarantee is gone — the price is unprotected

A SPAC's downside protection is not the cash in trust; it is your right to demand that cash. Once the redemption window closes, the cash stays with the company and the share can trade anywhere.

Redemption deadlinethe last day to hand shares back for cash

Set by the filing that calls the meeting. Tender after it and the company is under no obligation to pay you the trust value.

Broker action datethe day your broker needs the instruction — earlier than the official date

Brokers batch redemption instructions to the transfer agent, so the practical cutoff is roughly two business days before the published deadline. This is the date that actually costs people the floor.

Cash in trust / trust per sharethe cash the company is holding for each public share

Filed quarterly in the 10-Q's XBRL. It earns interest between filings, so the figure on a given day is slightly higher than the last filed one — where we show that we label it an estimate.

Trust discountbuying below the cash held for you

Only meaningful while a redemption right exists. On a floorless name the same arithmetic is not a discount, it is the market pricing distress, and this product will not call it a yield.

Dilutionhow much of the company new shares take from you

Sponsor promote, PIPE shares, warrants and rights all issue stock that did not pay $10 for it. The headline deal value is before that; the effective value is after.

Pro-forma equitywhat the company is valued at once the deal closes

The combined company's equity value assuming the announced terms and the redemptions that have actually happened.

ARShow much upside you get per unit of downside

SpacBrain's asymmetric-return score. It is deterministic — the same inputs always produce the same number — and it is capped, not zeroed, when the floor is gone.

De-SPACthe day the SPAC becomes the real company

The shares stop being a claim on a pot of cash and start being equity in an operating business. Roughly 80% of recent de-SPACs traded below $10 within a year.

Outside datethe contractual long-stop for closing the deal

A deadline between the SPAC and its target, not between the SPAC and you. It confers no right to cash, which is exactly why it must never be counted as a redemption window.

Accession numberthe SEC's unique id for one filing

Every figure on this page carries the accession of the filing that states it, so you can open the primary document rather than trust us.

Accreted NAV (estimate)the last filed cash figure, plus the interest it should have earned since

A model, not a filing: last filed value compounded at the 3-month T-bill for the days elapsed. Always shown in italic with the word estimate, and never printed beside a filed number without it.
