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 Rice (Rogers James Wilmot), listed on NYSE in October 2020.
What it's doing now
It agreed to buy Archaea Energy Inc., a renewable natural gas production from landfill gas 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

RICE 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

Rice Acquisition Corp. was a blank-check company whose common stock traded on the New York Stock Exchange under the ticker LFG, classified under SEC SIC industry code 4932 (Gas & Other Services Combined). The company priced its initial public offering on October 23, 2020, pursuant to a 424B4 prospectus (accession 0001213900-20-033072) filed under S-1 registration statement 0001213900-20-030317 (SEC file number 333-249340), which registered shares sold for cash. The registrant described itself as a blank-check company in that same prospectus. The company completed a business combination and no longer files under its original registration, as evidenced by Form 25 (accession 0000876661-22-001206) filed on December 28, 2022, under 17 CFR 240.12d2-2(a)(3), indicating that the shares came to evidence other securities in substitution therefor. The successor registrant, NET Power Inc. (ticker NPWR, CIK 0001845437), filed an 8-K with item 2.01 (Completion of Acquisition) naming Rice Acquisition Corp., and EDGAR now lists the original CIK (0001823766) under the name Archaea Energy Inc.

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.

  • DEFM14A14 November 20220001213900-22-071460opens on sec.gov in a new tab

    This is a cash sale of the de-SPAC to a strategic buyer rather than another business combination. Each Class A share and each Opco Class A Unit held immediately prior to the effective time receives $26.00 in cash without interest, less applicable withholding, unless the holder seeks and perfects statutory appraisal rights under Delaware law; each Class B share is automatically cancelled and extinguished with no conversion and no consideration paid for it. The merger cannot be completed unless holders of a majority of the outstanding shares entitled to vote adopt the merger agreement.

  • PREM14A2 November 20220001213900-22-068384opens on sec.gov in a new tab

    This is the preliminary form of the take-private of the vehicle that resulted from Rice Acquisition Corp.'s business combination. Each Class A share and each Opco Class A Unit receives $26.00 in cash without interest, less applicable withholding taxes, unless the holder seeks and perfects statutory appraisal rights under Delaware law, and each Class B share is automatically cancelled and extinguished with no consideration paid for it. The Archaea board unanimously declared the merger advisable and approved it together with the Warrant Agreement Amendment and the Opco LLC Agreement Amendment.

  • DEFM14A12 August 20210001213900-21-042041opens on sec.gov in a new tab

    This is two acquisitions put to one meeting, each under its own Business Combination Agreement dated April 7, 2021 and each with its own equityholder representative — Aria Renewable Energy Systems LLC for one, Archaea Energy LLC and Archaea Energy II LLC for the other. The targets sit four levels below the public company: RAC, then RAC Opco, then RAC Intermediate, then RAC Buyer, which is the entity that ends up holding both. A RAC holder's interest in the operating businesses is therefore indirect.

  • PREM14A14 May 20210001213900-21-026394opens on sec.gov in a new tab

    The two deals are paid very differently. Aria's members are to receive approximately $680.0 million, of which $450.0 million is cash and the rest is 23.0 million Class A units of RAC Opco plus 23.0 million shares of Class B Common Stock; Archaea's members receive approximately $347.0 million entirely in Class A units and Class B shares at a value of $10.00 per share, with no cash at all. The $450.0 million cash leg is what redemptions bear on, and the fee table values the combined transaction at $1,027,000,000.

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.

RICE — 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 4932 (Gas & Other Services Combined). The screen found it by filing SHAPE instead — S-1 2020-10-06 → 8-A12B 2020-10-21 → 424B4 2020-10-23 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts. SIC 4932 + self-described blank check in 424B4 0001213900-20-033072; 424B 0001213900-20-033072 priced 2020-10-23 under S-1 0001213900-20-030317 (file 333-249340, an offering for cash); common ticker RICE off 10-Q 0001213900-21-029395 (2021-05-26); lifecycle EXITED. The pricing prospectus was filed under SEC file number 333-249340, which belongs to S-1 0001213900-20-030317 (2020-10-06) — 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 2020-10-23). Ending PROVEN, not inferred: CLOSED per Form 25 0000876661-22-001206 (2022-12-28) — 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: Class A Common Stock); the successor registrant NET Power Inc. (NPWR, NPWR-WT) (CIK 0001845437) filed an 8-K carrying item 2.01 (Completion of Acquisition) naming "Rice Acquisition Corp." — the SPAC merged into a new registrant and so filed no closing report of its own. EDGAR now files this CIK as "Archaea Energy Inc." — 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.
