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 AQR Capital Management Holdings, LLC, listed on Nasdaq in October 2021.
What it's doing now
It agreed to buy Spectaire Holdings Inc.. 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

PCCT 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

Perception Capital Corp. II is a Cayman Islands-exempted blank check company formed to effect a merger, share exchange, asset acquisition, share purchase, reorganization, or similar business combination with one or more businesses, focusing on technology-enabled companies with proven business models benefiting from secular tailwinds in Industrial Technology, including Industrial Automation (mobility, robotics, additive manufacturing, IoT) and Sustainability (energy storage, hydrogen economy, waste-to-energy, clean food and water). The SPAC priced its IPO on October 29, 2021, raising $200 million by offering 20,000,000 units at $10.00 each on Nasdaq under the ticker PCCTU, with each unit comprising one Class A ordinary share and one-half of one redeemable public warrant; the common stock and warrants traded separately under symbols PCCT and PCCTW. The trust account, held at J.P. Morgan Chase Bank, N.A., was funded at $10.15 per unit ($203 million, or $233.45 million if the over-allotment was exercised in full). The sponsor, Perception Capital Partners II LLC, was affiliated with Northern Pacific Group and controlled by AQR Capital Management Holdings, LLC as a 10% owner. Chairman Scott Honour and CEO Rick Gaenzle brought roughly sixty years of combined investing experience across over 200 transactions, while Co-Presidents James Sheridan and Patrick Williams contributed operational expertise in automotive, building products, and energy sectors; the team had previously sponsored the public listing of Innoviz Technologies via Collective Growth Corporation.

The business-combination deadline was 12 months from the IPO closing, extendable up to 18 months if the sponsor exercised two three-month extension options by depositing $0.10 per public share into trust. The SPAC ultimately completed a business combination and changed its shell company status, as reported in an 8-K filed October 27, 2023, adopting the name Spectaire Holdings Inc. and now trading on OTC markets under the ticker SPEC in the Electronic Equipment and Instruments industry. The entity is classified as closed.


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.

  • A ratio range extending to 1-for-75 is among the most severe compressions a board can request and follows a May 6, 2024 Nasdaq deficiency letter, so the shares are trading at a small fraction of the $1.00 minimum bid requirement less than a year after the de-SPAC. The company states the split is also intended to support potential business and financing transactions, which means new issuance is expected once the price is reset, compounding dilution for existing holders. Holding the meeting physically in Ontario with no virtual option further limits participation by U.S. retail holders.

  • The warrant leg here is LARGER than the share leg: 11,500,000 warrants and the 11,500,000 shares they would become, against only 7,868,016 registered shares. Counting the share line alone would understate the potential issuance by more than half, so the warrant overhang is the dominant dilution factor in this registration. The domestication moves the surviving company to Delaware law before the merger. No vote date is stated in this portion.

  • Warrant shares are the larger half of the registration: 11,500,000 of the 19,368,016 total, against 7,868,016 issued in the merger itself. At the domestication both Class A and Class B ordinary shares convert one-for-one into a single class of NewCo common stock of $0.0001 par value, so the founder and public classes merge, and any unit not previously separated is cancelled for one share plus one-half of one warrant. Spectaire's stockholders, option holders and RSU holders receive NewCo stock plus a right to Spectaire Earnout Shares.

  • The two registered amounts are far out of proportion: 2,080,915 shares are issued in the domestication against 11,500,000 warrants and up to 11,500,000 shares issuable on their exercise, so the warrant overhang is several times the share base it attaches to. Class A and Class B ordinary shares both convert one-for-one into a single class of NewCo common stock, and an unseparated unit yields one share and one-half of one warrant. Spectaire's holders receive NewCo shares plus Spectaire Earnout Shares, whose amounts are not stated on the cover.

  • What is registered here is the domestication rather than the merger consideration: 2,080,915 shares against 11,500,000 warrants, so the warrants outnumber the shares this prospectus covers by more than five to one. Class A and Class B ordinary shares of $0.0001 par value both convert one-for-one into a single class of NewCo common stock, and an unseparated unit is cancelled for one share and one-half of one warrant. Spectaire's holders, option holders and RSU holders receive NewCo common stock plus a right to Spectaire Earnout Shares.

  • The registered amounts are lopsided from this first version: 2,080,915 shares against 11,500,000 warrants, so the warrant overhang is several times the share base created in the domestication. Class A and Class B ordinary shares both convert one-for-one into a single class of NewCo common stock, and an unseparated unit yields one share and one-half of one warrant. Spectaire's holders receive NewCo shares plus Spectaire Earnout Shares whose size is not stated on the cover, and the registrant's own cover footnote misspells the new name as Spectiare Holdings Inc.

Show 1 more material filings
  • At the Domestication both PCCT Class A and Class B ordinary shares convert one-for-one into a single class of NewCo common stock, so founder shares and public shares end up in the same class, and each PCCT warrant becomes a warrant over one NewCo share under the warrant agreement dated October 27, 2021. A unit not previously separated is cancelled in exchange for one share and one-half of one warrant. Beyond the combination and the Domestication, holders face four separate Organizational Documents Proposals and a Director Election Proposal. The meeting date is blank.

  • What changed: Spectaire Holdings Inc. (successor to SPAC Perception Capital Corp. II) called an in-person special meeting for July 22, 2024 at 10:00 a.m. Eastern Daylight Time at 5285 Solar Drive, Mississauga, Ontario, record date June 14, 2024, with materials distributed on or about June 29, 2024. Proposal 1 would amend the certificate of incorporation to authorise a reverse stock split within a range of 1-for-20 to 1-for-75, the exact ratio to be set by the board. On May 6, 2024 the company received a letter from the Nasdaq Listing Qualifications Department. Why it matters: A ratio range extending to 1-for-75 is among the most severe compressions a board can request and follows a May 6, 2024 Nasdaq deficiency letter, so the shares are trading at a small fraction of the $1.00 minimum bid requirement less than a year after the de-SPAC. The company states the split is also intended to support potential business and financing transactions, which means new issuance is expected once the price is reset, compounding dilution for existing holders. Holding the meeting physically in Ontario with no virtual option further limits participation by U.S. retail holders.

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.

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 3829 (Measuring & Controlling Devices, NEC). The screen found it by filing SHAPE instead — S-1 2021-04-07 → 8-A12B 2021-10-27 → 424B4 2021-10-29 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts.

The pricing prospectus was filed under SEC file number 333-255107, which belongs to S-1 0001193125-21-109040 (2021-04-07) — 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 2021-10-29). Ending PROVEN, not inferred: CLOSED per 8-K 0001013762-23-007283 (2023-10-27) — 8-K item 5.06 "Change in Shell Company Status" (EDGAR item index, items: 1.01,2.01,3.02,4.01,5.01,5.02,5.05,5.06,9.01). 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.
