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, listed on Nasdaq in January 2021.
What it's doing now
It agreed to buy GreenLight Biosciences Holdings, PBC, a RNA-based vaccines and therapeutics development 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

ENVI 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 priced its initial public offering on January 15, 2021, under SEC file number 333-251593. Its SEC CIK is 0001822691, and it operated under SEC SIC industry code 2836 (Biological Products, (No Diagnostic Substances)).

EDGAR now files this CIK as GreenLight Biosciences Holdings, PBC.


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.

  • The consideration basis is again an implied GreenLight equity value of $1.2 billion, with GreenLight capital stock exchanged for ENVI Class A common stock and options and warrants converted into comparable ENVI instruments, and the prospectus again covers 120,000,000 shares as a maximum. Two days separate this amendment from the previous one and the read portion is identical apart from the amendment number and the date, so what changed lies outside it. Nothing substantive is recorded here on the strength of the difference in numbering alone.

  • The consideration basis restated here is an implied GreenLight equity value of $1.2 billion, with GreenLight capital stock exchanged for ENVI Class A common stock and GreenLight options and warrants converted into comparable ENVI instruments. The prospectus covers 120,000,000 shares as a maximum rather than an expectation. What this amendment altered is not visible in the portion of the document read: the cover, the transaction description and the covered share count match the neighbouring amendment word for word. No substantive change is recorded, rather than one being inferred.

  • The exchange is fixed to a valuation rather than to a share count: each outstanding share of GreenLight capital stock is exchanged for ENVI Class A Common Stock, and GreenLight options and warrants, vested or unvested, convert into comparable ENVI instruments, in each case based on an implied GreenLight equity value of $1.2 billion. The 120,000,000 shares the prospectus covers are described as the maximum issuable to GreenLight's stockholders, optionholders and warrantholders, so the figure is a ceiling and not the consideration.

  • Consideration is set by an implied GreenLight equity value of $1.2 billion rather than by a fixed share count: GreenLight capital stock is exchanged for ENVI Class A common stock and GreenLight options and warrants convert into comparable ENVI instruments on that basis. The prospectus covers 120,000,000 shares, the maximum issuable to GreenLight holders rather than the expected number. ENVI's own Class A and Class B shares all become New GreenLight common stock. The proposed Nasdaq symbol is left blank, and conditional Nasdaq approval of the listing application is a closing condition.

  • The prospectus cover carries no share count at all, so a holder cannot size the dilution from this version — the figure that matters is simply absent where comparable filings print it. The document is marked preliminary and subject to completion, so the securities may not be sold until the registration statement is effective, and no meeting date is stated. ENVI's stockholders are asked to consider and vote upon the Business Combination and the other proposals described in the proxy statement/prospectus.

  • The 120,000,000 is stated on the assumption that every outstanding option and warrant to acquire GreenLight common stock is exercised before the closing, so it is a fully diluted ceiling rather than a count of shares actually delivered, and holders who do not exercise reduce it. The fee table carries no separate line for an earnout or for assumed equity awards, so 120,000,000 is the whole registered amount. The $9.84 is a market average used only to compute the fee.

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.

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 2836 (Biological Products, (No Diagnostic Substances)). The screen found it by filing SHAPE instead — S-1 2020-12-21 → 8-A12B 2021-01-13 → 424B4 2021-01-15 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts. SIC 2836 + self-described blank check in 424B4 0001213900-21-002606; 424B 0001213900-21-002606 priced 2021-01-15 under S-1 0001213900-20-043891 (file 333-251593, an offering for cash); common ticker ENVI off 10-Q 0001213900-21-058266 (2021-11-12); lifecycle EXITED. The pricing prospectus was filed under SEC file number 333-251593, which belongs to S-1 0001213900-20-043891 (2020-12-21) — 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 2021-01-15). Ending PROVEN, not inferred: CLOSED per Form 25 0001354457-23-000521 (2023-07-24) — 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: Common Stock & Warrant). EDGAR now files this CIK as "GreenLight Biosciences Holdings, PBC" — the SPAC's own name is kept here and the successor is the target. 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.
