Nothing left to do

The cash went back to shareholders and the company wound up. There is no deadline left to miss.

Trust settled · There is no line to draw here. This vehicle has finished: the cash was paid back or spent closing the deal, so the last filed figure describes an account that no longer exists and would be a floor under nothing.

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 SPG Sponsor, LLC, listed on NYSE in February 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

SPGS 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

Simon Property Group Acquisition Holdings, Inc. was a blank-check company whose common stock traded on the New York Stock Exchange under the ticker SPGS. The company priced its initial public offering on February 22, 2021, according to a 424B prospectus filed with the SEC. Its SEC SIC industry code was 6770 (Blank Checks) and its CIK was 0001839127. The company subsequently liquidated, returning trust cash to shareholders, with the redemption of its Class A Common Stock and Units reflected in a Form 25 filed on December 16, 2022. The SPGS ticker appeared on the cover page of an 8-K filed on December 15, 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.

  • Management's explicit conclusion that no combination is achievable converts this from an extension question into a liquidation decision, and the accelerated December 16 date exists so redemptions complete before the 1% excise tax applies to repurchases after December 31, 2022. Removing the net tangible asset limitation ensures every public share can be redeemed rather than only a portion. Holders receive the trust amount less taxes and up to $100,000 of interest reserved for dissolution expenses, with no residual deal exposure.

  • The price test is the short one: the $18.00 call fires on 10 TRADING DAYS WITHIN A 20-TRADING-DAY period ending three trading days before the notice, not the 20-of-30 the tier otherwise uses. That is the second document in this slice with the shortened window - Sports Entertainment Acquisition's 424B4 of October 2020 is the other - which makes it a variant rather than a typo, and one that lets the company call the warrants on half the sustained strength. Charter amendments need 65%.

  • What changed: Simon Property Group Acquisition Holdings, Inc. set a special meeting for December 15, 2022 at 9:30 a.m. Eastern at the offices of Paul, Weiss to move its termination date forward from February 18, 2023 to December 16, 2022, with a matching amendment to the February 18, 2021 trust agreement and a proposal removing the NTA limitation on the optional redemption. Management states that given current market volatility it is unlikely it can complete an initial combination by either the original or amended termination date. Why it matters: Management's explicit conclusion that no combination is achievable converts this from an extension question into a liquidation decision, and the accelerated December 16 date exists so redemptions complete before the 1% excise tax applies to repurchases after December 31, 2022. Removing the net tangible asset limitation ensures every public share can be redeemed rather than only a portion. Holders receive the trust amount less taxes and up to $100,000 of interest reserved for dissolution expenses, with no residual deal exposure.

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.
