SpacBrain’s read

Trust settled

The trust was liquidated and paid back to holders pro rata — the floor was honoured and the SPAC has wound up, so there is nothing left to claim.


In plain terms

What it is
A SPAC from Oyster Enterprises LLC, listed on Nasdaq in January 2021.
What it's doing now
It never completed a purchase. The company wound up and the cash in the account went back to shareholders — the ordinary ending when a SPAC runs out of time. No agreed deal for it is on file with us, so we cannot say whether one was ever announced and later fell through.
What you should know
This SPAC has finished. The cash was paid back to shareholders and the company wound up, so there is nothing left to claim — the money went where the charter said it would.

Cash held per sharenot filed for this window

This vehicle has finished, so there is no window to file a cash-per-share figure for and none will follow. No estimate is shown in its place.

Next date that mattersno dated event on file

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.

The score

deterministic, from filed fields

OSTR 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 — 295 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

Oyster Enterprises Acquisition Corp. was a blank-check company whose common stock traded on the Nasdaq Stock Market under the ticker OSTR. The company priced its initial public offering on January 21, 2021, per a 424B prospectus, with units consisting of a $10 trust amount per unit, a one-half warrant, and a 12-month deadline. It operated under SEC CIK 0001834226 and SIC industry code 6770 for blank checks. The company subsequently liquidated and returned the trust cash to shareholders, an ending established by a Form 25 filed on December 19, 2022.


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.

  • This is a full wind-up: all 23,000,000 public shares are redeemed and the $5,000,001 net tangible asset floor is removed precisely so the trust can be emptied to zero. The 65% supermajority requirement is a real hurdle, and failure would leave the vehicle running to January 22, 2023 with redemptions then falling after December 31, 2022, when the 1% excise tax applies. Holders therefore have a direct financial interest in approving promptly rather than allowing the timetable to slip into the taxed period.

  • The cover reports the capital structure in a form no other filing in this slice uses - '22,292,600 Units, 707,400 shares of Class A common stock and 5,750,000 shares of Class B common stock' as of 23 March 2021 - counting unseparated units rather than shares. It reconciles (22,292,600 + 707,400 = 23,000,000 Class A) but a share-count extractor reading the cover would take 707,400 as the Class A total. The deferred fee of $8,050,000 is $0.35 on all 23,000,000 units, so it already reflects the over-allotment.

  • Two features are stated and not standard. Private placement warrants bought by the UNDERWRITERS are deemed underwriters' compensation under FINRA Rule 5110, so part of the sponsor-side warrant block is regulated as fees. And the extension route is explicit: a charter amendment extending the 24-month period requires approval by holders of 65% of outstanding common stock. Redemption values, both at a business combination and on failure to close, are stated net of 'permitted withdrawals' — interest taken from the trust to pay taxes — and less up to $100,000 of interest for dissolution expenses.

  • Two features here are stated and not standard. Private placement warrants bought by the UNDERWRITER are deemed underwriter's compensation under FINRA Rule 5110, so part of the sponsor-side warrant block is regulated as fees. And the extension route is explicit: if a business combination is not completed within the 24-month period the company may seek a charter amendment to extend, which the amended and restated certificate of incorporation requires holders of 65% of outstanding common stock to approve. Redemption values are stated net of permitted withdrawals to pay taxes.

  • What changed: Oyster Enterprises Acquisition Corp. called a special meeting for December 19, 2022 at 11:00 a.m. Eastern to amend its charter to move the termination date forward from January 22, 2023 to a board-determined date no later than December 30, 2022, to remove the redemption limitation so it can redeem all 23,000,000 Class A shares even though that leaves net tangible assets below $5,000,001, and to allow removal of up to $100,000 of trust interest to pay dissolution expenses. Approval requires the affirmative vote of at least 65% of the outstanding Class A common stock. Why it matters: This is a full wind-up: all 23,000,000 public shares are redeemed and the $5,000,001 net tangible asset floor is removed precisely so the trust can be emptied to zero. The 65% supermajority requirement is a real hurdle, and failure would leave the vehicle running to January 22, 2023 with redemptions then falling after December 31, 2022, when the 1% excise tax applies.

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.
