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 June 2021.
- What it's doing now
- It agreed to buy Net Power Inc., a clean power generation technology 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.

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.
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.

deterministic, from filed fieldsRONI 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.

The company
from SEC filingsRead the full profile
Rice Acquisition Corp. II was a blank-check company whose common stock traded on the New York Stock Exchange under the ticker RONI, registered with the SEC under CIK 0001845437 and classified under SIC industry code 3620 (Electrical Industrial Apparatus). The company priced its initial public offering on June 17, 2021, as disclosed in a 424B4 prospectus (accession 0001213900-21-032979) filed under SEC file number 333-254080, which corresponded to an S-1 registration statement (accession 0001213900-21-014553) filed on March 10, 2021, for the sale of shares for cash. The registrant described itself as a blank-check company in that same prospectus. Its units each consisted of one Class A ordinary share and one-fourth of one redeemable warrant. The vehicle completed a business combination and no longer files, with the closing established by Form 25 (accession 0000876661-23-000474) filed on June 9, 2023, under 17 CFR 240.12d2-2(a)(3), reflecting that the securities came to evidence other securities in substitution therefor. EDGAR now files CIK 0001845437 under the name Net Power Inc.
Material findings
from the full read of every filingEvery 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 expiry of the Entropy letter of intent removes the only carbon-capture licensing arrangement the company had described, and the filing states plainly that no definitive agreement exists. The financial statements are not covered by this summary.
199,845,063 registered shares is the ceiling on issuance and by far the largest number a RONI holder is being asked to approve. Two domestications occur on the closing date rather than one: the vehicle becomes a Delaware corporation and its operating subsidiary becomes a Delaware limited liability company, the Up-C plumbing that leaves NET Power's equity holders in the operating company. Class A and Class B ordinary shares convert into Class A and Class B common stock respectively, so the two classes survive the move rather than collapsing into one.
199,845,063 shares is the ceiling on issuance and the measure of what a non-redeeming RONI shareholder is diluted by, with warrants over a further 19,525,000 shares on top of it. Four amendments in, the meeting still carries no date, so no redemption deadline can be computed from this version. The Domestication and the Business Combination are both put to the same extraordinary general meeting, so a holder approving the deal is also approving the move from Cayman Islands law to Delaware law.
The registered amounts are settled at this version — 199,845,063 shares plus warrants over a further 19,525,000 — so a RONI shareholder can size the dilution even though the meeting has no date. What stays open is the timetable: three amendments in, neither the day nor the hour of the extraordinary general meeting is fixed, so no redemption deadline can be computed from the document. The Domestication and the Business Combination are put to the same meeting, so approving one means approving the change of governing law.
198,350,578 shares is the ceiling on issuance and therefore the measure of dilution for a RONI shareholder who does not redeem, with warrants over a further 19,525,000 shares on top of it. Shareholders are asked to approve the Domestication and the Business Combination as separate items at the same meeting, so the move from the Cayman Islands to Delaware is a distinct vote rather than a consequence of approving the deal. No meeting date is fixed at this version, so no redemption deadline can be read from it.
Two entities change jurisdiction, not one: the SPAC and its operating subsidiary both domesticate in Delaware, which keeps the Up-C structure intact through the transaction. RONI's Class A ordinary shares become Class A common stock and its Class B ordinary shares become Class B common stock, so the two-class structure survives rather than collapsing into a single class. The extraordinary general meeting is to be held at 609 Main Street, Houston, Texas on a date and at a time both left blank, so no redemption deadline can be read from this version.

198,350,578 shares is the registered ceiling at this first version and therefore the measure of dilution for a RONI shareholder who does not redeem, with warrants over a further 19,525,000 shares beyond it. Shareholders are asked to approve the Domestication and the Business Combination as separate items at the same meeting, so the move from the Cayman Islands to Delaware is its own vote rather than a consequence of approving the deal. No meeting date is fixed, so nothing here sets a redemption deadline.
Filings
live EDGAR feedEverything this company has filed with the SEC recently, newest first, each with a plain summary of what changed and why it matters.
What changed: Q2 2026 10-Q of NET Power Inc. (NYSE: NPWR). The 'Certain Defined Terms' section states that the November 7, 2025 letter of intent with Entropy Inc. — non-binding except for customary provisions, contemplating joint development and exclusive US power-generation deployment of Entropy's post-combustion carbon capture technology — has expired by its terms and has not been replaced, that the company has not entered into a definitive agreement for the license of PCC technology, and that either party may discontinue negotiations at any time. Why it matters: The expiry of the Entropy letter of intent removes the only carbon-capture licensing arrangement the company had described, and the filing states plainly that no definitive agreement exists. The financial statements are not covered by this summary.
What changed: Net Power Inc. (NYSE: NPWR) reported under Item 2.02 that on August 13, 2026 it issued a press release setting out its financial results for the quarter ended June 30, 2026, furnished as Exhibit 99.1. The results themselves are not contained in this document, and the filing states the information is furnished and not deemed filed for purposes of Section 18. Why it matters: The 8-K records only that results were released; the figures are in the furnished exhibit and carry no Section 18 liability.

In plain English
tap a term to open itEvery 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 3620 (Electrical Industrial Apparatus). The screen found it by filing SHAPE instead — S-1 2021-03-10 → 8-A12B 2021-06-15 → 424B4 2021-06-17 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts. SIC 3620 + self-described blank check in 424B4 0001213900-21-032979; 424B 0001213900-21-032979 priced 2021-06-17 under S-1 0001213900-21-014553 (file 333-254080, an offering for cash); common ticker RONI off 10-Q 0001213900-23-039061 (2023-05-12); lifecycle EXITED. The pricing prospectus was filed under SEC file number 333-254080, which belongs to S-1 0001213900-21-014553 (2021-03-10) — 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 2021-06-17). Ending PROVEN, not inferred: CLOSED per Form 25 0000876661-23-000474 (2023-06-09) — 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: Rice Acquisition Corp. II - Units, each consisting of one Class A ordinary share and one-fourth of one redeemable warrant). EDGAR now files this CIK as "Net Power 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.
