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 Longevity Acquisition Corp / Model Performance Acquisition Corp / Tenzing Acquisition Corp. (Gerber Sander), listed on Nasdaq in August 2018.
What it's doing now
It agreed in February 2021 to buy 4D pharma plc, a Clinical-stage biopharmaceutical company developing live biotherapeutic products company. The deal valued that business at about $45.1M. 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.

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

LOAC 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

Longevity Acquisition Corp (LOAC) was a blank-check company whose common ticker LOAC traded on the Nasdaq Stock Market. The company priced its initial public offering on August 29, 2018, as reflected in 424B prospectus filing 0001144204-18-047150. Its SEC CIK is 0001743858 and its SIC industry code is 6770 (Blank Checks). The ticker LOAC appears on the cover page of an 8-K filed on March 18, 2021 (accession 0001104659-21-038087). The company's lifecycle is closed: it completed a business combination and no longer files, with the closing established by Form 25 filed on March 22, 2021 (accession 0001354457-21-000373) under 17 CFR 240.12d2-2(a)(3), indicating that its Ordinary Shares, Rights, Units, and Warrants 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.

  • Two cash tests must be met immediately prior to the effective time: Longevity must have at least $11.8 million of net tangible assets and at least $14.6 million in cash, so redemptions can defeat the transaction directly. Completion also depends on 4D pharma's own shareholders, two of whose approvals are special resolutions requiring 75% of votes cast. Whale Management Corporation, holding approximately 47.6% of Longevity's capital, has signed a voting and support agreement. Longevity's shareholders are expected to own approximately 17.7% of 4D pharma against 82.3% for existing holders.

  • Roughly two thirds of the original $40m trust has left through redemptions and the shell now holds $19,330 of cash against $418,291 of current liabilities - it is running on insider notes, which together exceed $2.0m. The $1,000,000 deferred underwriting fee is now about 7% of what remains in trust, a far heavier drag on closing cash than at IPO. Trust and share figures are as of November 30, 2020, and this issuer has redeemed repeatedly, so they date quickly.

  • Two cash tests gate the closing: Longevity must have at least $11.8 million of net tangible assets and at least $14.6 million in cash immediately before the effective time, so redemptions can break the transaction outright. Completion also requires 4D Pharma's own shareholders to pass a section 551 allotment resolution by simple majority and two special resolutions at 75%, to disapply pre-emption rights and to amend the articles to create the ADSs. Whale Management Corporation, holding about 47.6% of Longevity, has signed a voting and support agreement.

  • It repairs the arithmetic that did not reconcile in the definitive proxy, where a claimed one-cent gain sat beside a $0.025 monthly contribution paragraph carried over unedited from the May 2020 round. From this supplement forward the per-month rate for the extension to 29 May 2021 is $0.05 per remaining share, and the supplement states it 'shall be deemed to have superseded the Proxy Statement' wherever they conflict. Holders who had already voted need do nothing, so the improved terms arrive without a re-solicitation — and the payment remains contingent on the sponsor performing.

  • It is the public, non-proxy channel for the same term change, which matters for sequencing: a holder reading only the mailed proxy would have had the old rate, and the improvement was announced three days before the meeting. The filing's own risk language is the caveat to carry forward — it lists 'the ability of the Company's sponsor to make the Revised Contribution' among the things that may not happen, so this is a promise, not cash in trust. Duplicate disclosure of one fact across an 8-K and a supplement is normal and must not be counted as two separate improvements.

  • Two figures in this document do not reconcile, and a reader should be told rather than shown one of them. It says that taking the full time to the Extended Date yields 'approximately $10.75 per share, in comparison to the current redemption amount of $10.74 per share' — an increase of about one cent — while the contribution paragraph describes $0.025 per share per month, and that paragraph's worked example still ends at 30 Nov 2020 and calls it six calendar months, i.e. it was not updated from the May 2020 proxy. Treat both the $10.75 and the $600,000 as unverified for THIS extension.

  • It changes what the pending extension vote is FOR. Longevity's 20 Nov 2020 special meeting proxy, mailed as a search-mode extension, is now backed by a signed transaction, and the two must be kept distinct: this merger carries its own shareholder vote and its own redemption election under a proxy statement/prospectus not yet filed at this date. Longevity is the disappearing entity here — holders receive securities of 4D Pharma, an already-listed UK company — which is a different shape from a SPAC whose target becomes a new public company.

  • 29 May 2021 is a CEILING conditioned twice: it needs each monthly contribution funded, and the board may end it earlier. The contribution paragraph is carried over verbatim from the May 2020 proxy — its worked example still runs 'until November 30, 2020, which would represent six calendar months' for approximately $600,000 — so it describes the FIRST extension, not this one, and cannot be relied on for what the sponsor owes over the new period. Longevity was at this point still searching; the 4D Pharma merger agreement is signed six days after this filing.

  • Two thirds of the trust left in the June 3 redemption and the shell now runs on $14.5 million of trust against $3,128,979 of liabilities, $1.79 million of it owed to the sponsor. The $10.69 is an August 31, 2020 carrying value, not a redemption price, and the trust figure is already three months old at the filing date - the same as-of problem this company's previous 10-Q demonstrated when its trust was cut by two thirds three days after the balance-sheet date. Nothing was written to a trust, floor or price field.

  • A public-holders deficiency is a listing risk that runs on Nasdaq's clock rather than the SPAC's own. Note a date problem on the face of the document: the report is filed September 2, 2020 but dates the notice 'August 28, 2019', so the notice date as printed cannot be reconciled with the filing date or with the 45-day plan window described in the present tense. The notice date is therefore reported here as the document prints it, not relied on.

  • This is the clearest case in the slice of why a trust figure must be quoted with its date: $42,492,044 at May 31, 2020 was reduced by two thirds on June 3, before the filing was made, and the document says so itself. The company is also running on $1,744 of cash, with every extension deposit borrowed from the sponsor and repayable only on a closing. Detect-only: neither the trust, the approximately $10.61 redemption price, nor the November 30, 2020 date was written to any field.

  • The deadline genuinely moved — the charter amendment was filed in the BVI on May 27, 2020, so November 30, 2020 is an effected date rather than an authorised option. The price was 2,643,178 shares redeemed. On the trust, the report states '$14,401,874.06 million will remain in the Trust Account', which is internally inconsistent: the figure and the word 'million' cannot both be right, so no post-redemption trust balance is asserted here.

  • This is the filing that turns Longevity's extension into a dated election: the meeting, the record date and therefore the tender cut-off are all now stated, where the 21 Apr 2020 preliminary left the meeting blank. The Extended Date remains a CEILING funded in $0.025-per-share monthly instalments to a maximum of approximately $600,000, and the Extension Proposal needs 65% of the shares voting. The filing warns that failure either way — no extension by 29 May 2020, or no combination by the Extended Date — means winding up and redeeming 100% of public shares within ten business days.

  • Every dollar of the trust's growth above $40,000,000 is borrowed: $2,700,000 of liabilities now sit against the shell to keep it alive. The document also disagrees with itself by one day on its own outer date - the extension is described as running 'until May 28, 2020' in one place and 'by May 29, 2020' in two others - and a further extension to November 30, 2020 is only proposed, requiring a shareholder vote plus $0.025 per non-redeemed share per month (up to $600,000). Detect-only: nothing written to a deadline, trust or floor field.

  • 30 Nov 2020 is a CEILING reached only by funding six monthly instalments; the charter deadline as filed is 29 May 2020, and the filing conditions every contribution on the Extension being implemented, adding that if the sponsor says it will not pay, the proposals will not be put. The document frames the payoff as an estimate: 'approximately $10.75 per share' at a later business-combination vote or liquidation versus 'the current redemption amount of $10.60 per share (as of February 29, 2020 and assuming no public shares were redeemed)'. The 65% approval threshold is unusual and worth noting.

  • This is a completed extension rather than an option: the deposit was made and the report states the new date as a fact, not as something contingent on a further payment. The note bears no interest and is repayable in full only on consummation of the initial business combination, so on a liquidation the sponsor's $400,000 stays in trust for public shareholders and the note goes unpaid; that is a real transfer of value into the trust. The report gives no trust balance, no public share count and no redemption figures; the $0.10 per public share is the company's own characterisation.

  • The second same-day director resignation and replacement at this company in under two months, following the December 2, 2019 change on the Class I seat, with the incoming director again taking audit and compensation committee seats. The filing gives no reason beyond 'other professional interests' and discloses no disagreement.

  • Cash outside the trust is down to $91,731 while the convertible sponsor note has grown to $1,100,000 — the shell is now funding itself almost entirely on sponsor credit, and that credit is convertible, so a closing may settle it in securities rather than cash. Redemption value per redeemable share is approximately $10.47 ($34,854,352 over 3,330,524), up from approximately $10.11 at the year end, reflecting both trust earnings and the $400,000 extension deposit the sponsor made in November. The redeemable share count fell by 140,530 over the nine months.

  • A director departure and replacement on the same day, with the incoming director taking both an audit committee seat and the compensation committee chair. The filing gives no reason beyond 'other professional interests' and discloses no disagreement, which is the disclosure that would be required if there were one.

  • This is a charter-permitted extension bought with a sponsor deposit rather than voted on: $0.10 per public share into trust buys three months to February 28, 2020, so the deadline moves without a shareholder meeting and without a redemption opportunity. The deposit raises the trust and therefore the per-share redemption amount, while the matching liability sits outside the trust and is repayable only on a closing — if there is no closing, the note is not repaid.

  • Two balances moved in opposite directions over the six months: the trust grew by $861,372 on interest while operating cash fell by $499,347, and a $400,000 related-party convertible note appeared where there was none — the company was funding operating costs from sponsor credit rather than from cash on hand. Redemption value per redeemable share rose from about $10.11 to about $10.32 while the redeemable share count fell by 82,996, the reclassification that holds shareholders' equity at just over the $5,000,000 mark in both periods.

  • This is working capital funded outside the trust and expressly subordinated to it by the payee's trust waiver, so it cannot reduce the per-share redemption amount: it is repaid from a closing or ranks as an unsecured claim at winding up. Because each drawdown is discretionary on the payee's side, $800,000 is a ceiling on availability rather than committed cash, and the amount drawn is not stated here. Unlike some sponsor notes this one is freely prepayable by the company.

  • A fixed $400,000 of sponsor credit, repaid only on a closing and written off in a wind-up — funding a search whose own cash had fallen to about $439,000 at the May quarter end.

  • Redemption value accreted six cents in the quarter while cash outside the trust fell by nearly a third — trust income now exceeds the search cost, but the operating account is draining.

  • The first year's search cost slightly exceeded what the trust earned, so the company is running a small accumulated deficit — and $369,136 of the interest is attributed to redeeming shareholders rather than to the company.

  • Trust value per share has accreted above $10.00 while operating costs rose sharply in the quarter — the first quarter in which search expenses exceed trust income for this SPAC.

  • Opens the separate Nasdaq lines and settles the over-allotment: it lapsed unexercised, so the trust stays at $40 million and the sponsor's founder-share count drops by 150,000.

  • Establishes a $10.00 trust of $40 million with $1,000,000 of deferred underwriting against it, and about $1.06 million of cash outside trust — unusually well funded for a shell this size.

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.
