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 Highview Merger Corp. (Rettig Taylor), listed on NYSE in October 2020.
What it's doing now
It agreed to buy Archer Aviation Inc., an electric vertical takeoff and landing company. 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

ACIC 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

Atlas Crest Investment Corp. was a special purpose acquisition company (SPAC) headquartered at 190 West Tasman Drive, San Jose, California, and sponsored by Atlas Crest Investment LLC. The blank-check company priced its initial public offering on October 29, 2020, under SEC registration statement No. 333-249289, with its common stock listed on the New York Stock Exchange under the ticker symbol ACIC. Each unit consisted of one share of Class A common stock and one-third of one redeemable warrant, with the public warrants exercisable at $11.50 per share. In a concurrent private placement, the sponsor purchased 8,000,000 private warrants and 12,500,000 sponsor shares.

On February 10, 2021, Atlas entered into a Business Combination Agreement with Archer Aviation Inc., an electric vertical takeoff and landing (eVTOL) aircraft developer founded by Brett Adcock and Adam Goldstein. The transaction was amended and restated on July 29, 2021, and closed on September 16, 2021, following stockholder approval at a special meeting on September 14, 2021. The merger was effected through Artemis Acquisition Sub Inc., a wholly-owned subsidiary of Atlas, merging into Archer with Archer surviving as a wholly-owned subsidiary. A concurrent $600 million PIPE financing issued 60,000,000 Class A shares at $10.00 per share to subscribers. Upon closing, Atlas Crest Investment Corp. changed its name to Archer Aviation Inc., and the successor entity's securities began trading under the ticker symbols ACHR and ACHR WS.

The SPAC's lifecycle concluded when Form 25 was filed on September 17, 2021, under 17 CFR 240.12d2-2(a)(3), reflecting that the Atlas securities had come to evidence other securities in substitution therefor. EDGAR subsequently reassigned the registrant's Standard Industrial Classification from blank-check (6770) to Aircraft (3721). The successor company, Archer Aviation Inc., continues to trade on the NYSE and develops eVTOL aircraft for urban air mobility and defense applications, with United Airlines as its first major corporate partner having conditionally ordered 200 electric aircraft.


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.

  • 8,261,273 new Class A shares were issued to settle vendor obligations and are now registered for resale, so they can reach the market without a further registration step; the company took in no cash for them, which is the mechanical difference between this and an equity raise.

  • The company is burning cash rapidly ($305.5M operating cash outflow in H1 2026) but still has $1.56B in liquidity, which management states is sufficient for at least 12 months. The first revenue recognition and Hawthorne acquisitions mark early operational progress, but the SPAC warrants (ACHR WS at $0.12) are deeply out of the money at a $11.50 strike with only 0.21 years remaining.

  • The 8-K body states no financial figures; the quarter's results are only in the furnished exhibits. Archer separately filed the Boeing equity purchase agreement the same day (accession 0001104659-26-093056).

  • Archer is acquiring Boeing's Wisk and Insitu entities with consideration that includes Archer stock and warrants issued to Boeing, plus a governance side letter — so this is a share-issuing acquisition with an ongoing relationship, not a cash purchase as described. No purchase price, share count or closing date appears in the captured text.

  • One proposal failed. The redomestication of the company from Delaware to Texas did not receive the requisite stockholder approval, drawing 234,119,344 for against 44,503,590 opposed, 839,202 withheld and 201,849,581 broker non-votes. The company remains a Delaware corporation, and the size of the broker non-vote relative to the votes cast is the reason the proposal fell short rather than active opposition.

  • Doubling the authorized Class A count to 1,400,000,000 shares is the largest capital-structure expansion in this batch, and abstentions and broker non-votes count as votes AGAINST it, so uninstructed street-name shares actively work against passage. The paired Stellantis proposal is what the headroom is for — a strategic partner taking stock through a subscription agreement, a forward issuance agreement and warrants, approved under NYSE rules because of the size and the relationship.

  • With about 51.89% of the combined voting power already committed, the outcome of every item — including the officer exculpation amendment — is effectively settled before public holders vote. The pay table shows the scale involved: for 2023 compensation actually paid to the chief executive was $27,950,070 on a $1,003,750 summary total, and non-PEO named executives averaged $11,188,491 actually paid, against a net loss of $458 million and an initial fixed investment worth $101.66.

  • Archer's securityholders receive Class B stock rather than the Class A that Atlas Crest's own holders hold, and the Class B converts into Class A afterwards, so the registered Class A line is a conversion overhang and not a separate issuance. The dollar figures carry no valuation meaning: under Rule 457(f)(2) the aggregate offering price of $21,599.53 is one-third of the aggregate par value of the Archer securities to be exchanged, because Archer is private, no market exists for its securities and it has an accumulated deficit.

  • Splitting the table apart is what makes it readable: of the 215,995,224 shares now shown, 71,627,275 are employee stock options and equity awards and 18,225,777 are assumed warrants, so more than a third of the registered total is not closing consideration at all. The dollar figures remain a Rule 457(f)(2) construct — Archer is private, no market exists for its securities and it has an accumulated deficit — and the $7,248.56 fee is stated as included in the $119,824 previously paid.

  • The fee table's dollar figures say nothing about value: Archer is private, no market exists for its securities and it has an accumulated deficit, so under Rule 457(f)(2) the offering price is one-third of the aggregate par value of the Archer securities to be exchanged. Note also that the stated fee of $9,578 is smaller than the $119,824 it says was previously paid. The figure that measures the deal is 287,345,325 shares, of which 28,224,635 are warrant-related rather than closing consideration.

  • The registered stock is not all merger consideration: 87,616,000 shares are issuable to Archer Aviation, while a further 14,645,614 are issuable in respect of the United Warrant and the Mesa Warrant described in the filing. New Archer will have both Class A and Class B common stock, so voting power and economics are split across two classes rather than one. The $10.74 registration price is the March 5, 2021 average, roughly three months old by the date of this amendment, and is used only to compute the fee.

  • Archer's holders receive New Archer Class B Shares rather than the Class A being registered, on an exchange ratio derived from an implied equity value for Archer of $2,525,000,000, and Archer's options, restricted stock units and warrants all convert into Class B instruments at that same ratio. Restricted Archer shares carry their vesting and forfeiture terms across into the Class B shares issued for them. The separate 14,645,614 shares answer the United Warrant and the Mesa Warrant, which sit outside the merger consideration. Shares are priced at $10.74 for fee purposes on March 5, 2021.

  • Archer's holders receive New Archer Class B Shares rather than the Class A being registered, on an exchange ratio derived from an implied equity value for Archer of $2,525,000,000 — so the two classes are separated from the outset, and Archer's options, restricted stock units and warrants all convert into Class B instruments at that same ratio. A separate 14,645,614 shares answer the United Warrant and the Mesa Warrant, which sit outside the merger consideration. Shares are priced at $10.74 for fee purposes, the average of the high and low sales prices on March 5, 2021.

Everything this company has filed with the SEC recently, newest first, each with a plain summary of what changed and why it matters.

Show the other 10 filings
  • What changed: Archer Aviation filed its 10-Q for Q2 2026, reporting $852.7M cash and $707.9M short-term investments as of June 30, 2026, with 770.0M Class A shares outstanding. The company recognized $5.0M in revenue (first-ever quarterly revenue, from Hawthorne Airport FBO operations acquired April 1, 2026) and posted a net loss of $263.2M for the quarter. Why it matters: The company is burning cash rapidly ($305.5M operating cash outflow in H1 2026) but still has $1.56B in liquidity, which management states is sufficient for at least 12 months. The first revenue recognition and Hawthorne acquisitions mark early operational progress, but the SPAC warrants (ACHR WS at $0.12) are deeply out of the money at a $11.50 strike with only 0.21 years remaining.

  • What changed: Item 2.02 8-K of Archer Aviation Inc. (NYSE: ACHR). On August 10, 2026 the company held a conference call on its second quarter 2026 operating and financial results and issued both a letter to stockholders and a press release, furnished as Exhibits 99.1 and 99.2 and expressly not deemed filed for Section 18 purposes. The filing notes that non-GAAP financial information is referenced in the press release with a GAAP reconciliation included there. Why it matters: The 8-K body states no financial figures; the quarter's results are only in the furnished exhibits. Archer separately filed the Boeing equity purchase agreement the same day (accession 0001104659-26-093056).

  • What changed: Exhibit 2.1 to an 8-K of Archer Aviation Inc.: an Equity Purchase Agreement dated August 9, 2026 among The Boeing Company as seller, Wisk Aero LLC, Insitu, Inc., Insitu Pacific Pty Ltd, Wisk Australia Pty Ltd and Boeing Emirates Ltd (together the Companies), and Archer Aviation Inc. as buyer. Boeing or its affiliates own all of the equity of each of those five entities, and Archer is purchasing all of it. Why it matters: Archer is acquiring Boeing's Wisk and Insitu entities with consideration that includes Archer stock and warrants issued to Boeing, plus a governance side letter — so this is a share-issuing acquisition with an ongoing relationship, not a cash purchase as described. No purchase price, share count or closing date appears in the captured text.

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.

ACIC — company record
UNIVERSE-IPO-INDEX2026-08-17

admitted from EDGAR's QUARTERLY FORM INDEX, walked without any SIC filter. The SIC 6770 census could not reach this registrant: EDGAR reassigns a shell's SIC the day it stops being one, and this CIK now files under 3721 (Aircraft). The screen found it by filing SHAPE instead — S-1 2020-10-02 → 8-A12B 2020-10-27 → 424B4 2020-10-29 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts.

The pricing prospectus was filed under SEC file number 333-249289, which belongs to S-1 0001213900-20-029955 (2020-10-02) — a registration of shares sold for CASH, which is what makes it an IPO rather than merger consideration. Blank-check status from the registrant's own first-person sentence in that prospectus (EDGAR full-text search, 424B4 2020-10-29). Ending PROVEN, not inferred: CLOSED per Form 25 0000876661-21-001357 (2021-09-17) — Form 25 filed under 17 CFR 240.12d2-2(a)(3) — the rule for securities that "have come to evidence other securities in substitution therefor", i.e. the shares became the successor's (class: Units, each consisting of one Class A common stock, and one-third of one redeemable warrant). ipoSizeM and deadline left NULL: gross-proceeds prose conflates the over-allotment with the offering, and a charter deadline belonging to a vehicle that has ended is a date nobody can act on. ipoDate is the 424B pricing date.
