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 NYSE in February 2021.
What it's doing now
It agreed to buy Energy Vault Holdings, Inc., a gravity-based energy storage systems 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.

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

NXU 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

Energy Vault Holdings, Inc. was a blank-check company whose common stock traded on the New York Stock Exchange under the ticker NXU. The company priced its initial public offering on February 5, 2021, under SEC file number 333-252079, with shares registered for cash on S-1 form 0001104659-21-003895. The registrant self-described as a blank-check company in its 424B4 prospectus and was classified under SEC SIC code 3690 (Miscellaneous Electrical Machinery, Equipment & Supplies). On February 14, 2022, the company filed an 8-K (accession 0001104659-22-023106) reporting a change in shell company status under Item 5.06, establishing that it had completed a business combination and no longer files.


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.

  • This new secured debt facility layers on top of existing Yorkville (YA II PN, Ltd.) convertible debt arrangements (Original SPA Sept 2025, May 2026 SPA) and is tied to an Equipment Supply Agreement, indicating the post-SPAC company is aggressively levering up to fund operations and equipment purchases through 2027.

  • Revenue guidance of $270 to $310 million requires roughly $245 to $285 million in the second half against $17.4 million in the second quarter — the entire year rests on backlog conversion that has not yet appeared in revenue, and 60% of that backlog is explicitly long-dated owned-asset revenue rather than near-term deliveries. The two descriptions of the gross margin change in the same release are not the same act: raising a range's floor from 15% to 20% narrows it, and the release calls that both a lift and a narrowing.

  • The company itself flags that backlog and pipeline equating to future revenue is a forward-looking assumption rather than a fact, which is the frame a reader needs for the $2 billion backlog figure announced the same day. The condensed financial statements are not in the portion read here.

  • The facility nearly doubled from $42 million to $80 million in six weeks, and it converts into common stock, so the dilution overhang has grown in proportion. YA II PN is the same counterparty behind equity lines at other companies in this cohort, and its instruments typically convert at a discount to recent trading prices, meaning the share count expands faster as the price falls. For former NXU holders that is $80 million of convertible claims sitting ahead of the equity.

  • The fee table registers 123,817,989 shares of Class A common stock with no offering price per share, an aggregate of $547.43 and a fee of $0.05, previously paid. That aggregate is a Rule 457(f)(2) computation: Energy Vault is private, no market exists for its securities and it has an accumulated deficit, so the price is one-third of the aggregate par value of the securities to be exchanged. The share count is the only entry in the table that describes the transaction; the dollar figures describe the par value of the target's stock.

  • The fee is $0.05 on an aggregate of $547.43, because Rule 457(f)(2) values a private, loss-making target at one-third of aggregate par — the share count is the only usable figure in the table. The ratio's definition is 100,000,000 divided by Energy Vault's fully diluted share count, excluding Series C preferred from that denominator. Holders are also eligible for up to 9,000,000 Earn Out Shares on stated targets. The valuation sentences are unfinished as printed: the trust figure of $10.00 is tied to a record date left as January __, 2022, and the market-price alternatives read $[ ].

  • That aggregate is a Rule 457(f)(2) artefact, not a valuation: Energy Vault is private, no market exists for its securities and it has an accumulated deficit, so the price is one-third of the aggregate par value exchanged, and only the share count carries information. The letter values it differently — at the anticipated exchange ratio of 6.9419 Novus issues 108,963,033 shares said to be worth approximately $1.09 billion (the price and date behind it are left blank) plus up to 6,187,789 shares for options and restricted stock units. Up to 9,000,000 Earn Out Shares sit outside that count.

  • The $547.43 is a Rule 457(f)(2) construct — Energy Vault is private, no market exists for its securities and it has an accumulated deficit, so the price is one-third of the aggregate par value of the securities expected to be exchanged — and 115,150,822 is the only usable number in the table. The fee is computed at a rate of 0.0000927, so fee amounts here are not comparable with those in registration statements filed under a different SEC rate.

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: Energy Vault Holdings, Inc. (NYSE: NRGV) furnished a press release dated August 11, 2026 reporting second quarter 2026 results. Contract backlog reached $2 billion as of August 10, 2026, up $650 million sequentially, 47% quarter over quarter and 107% year over year, of which 40% is expected to convert to revenue over the next 12 to 18 months and 60% comes from owned and operated projects with long-term offtake agreements. Revenue was $17.4 million, up 104% from $8.5 million, GAAP gross profit $5.4 million at a 31.0% margin against 29.6%, and adjusted gross margin 38.6%. Why it matters: Revenue guidance of $270 to $310 million requires roughly $245 to $285 million in the second half against $17.4 million in the second quarter — the entire year rests on backlog conversion that has not yet appeared in revenue, and 60% of that backlog is explicitly long-dated owned-asset revenue rather than near-term deliveries. The two descriptions of the gross margin change in the same release are not the same act: raising a range's floor from 15% to 20% narrows it, and the release calls that both a lift and a narrowing.

  • What changed: The 10-Q filed under Commission file number 001-39982 is that of Energy Vault Holdings, Inc. (NYSE: NRGV) for the quarter ended June 30, 2026, with 181,839,570 shares outstanding as of August 6, 2026. Why it matters: The company itself flags that backlog and pipeline equating to future revenue is a forward-looking assumption rather than a fact, which is the frame a reader needs for the $2 billion backlog figure announced the same day. The condensed financial statements are not in the portion read here.

    Read from stored SEC filing text by a regex — no model is involved — and each side links to the filing it came from. “Not previously extracted” is a statement about our record, not about the company: the clause may be present in wording we do not match.

  • What changed: Energy Vault Holdings, Inc., the Novus Capital Corporation II successor, said its board appointed Nitin Dahiya, 49, as CFO on July 14, 2026, effective July 27, 2026. Dahiya has been a Senior Portfolio Manager at BlackRock since 2018 covering specialty finance and energy transition, and was previously at Paulson & Co. His offer letter provides an annual base salary of $435,000, an award of 400,000 restricted stock units, 400,000 performance restricted stock units vesting in three tranches on share price targets, a 75% annual bonus target and a $100,000 signing bonus. Why it matters: An 800,000-unit equity package for a single hire is the number a holder should note, and half of it vests only on the stock reaching specified price targets — management is being paid to move the share price, which is consistent with a company whose equity is well below its de-SPAC level. Hiring a credit and special-situations investor rather than an operating accountant as CFO also suggests financing or restructuring work ahead rather than routine reporting.

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.

Blank-check status from the registrant's own first-person sentence in that prospectus (EDGAR full-text search, 424B4 2021-02-05). Ending PROVEN, not inferred: CLOSED per 8-K 0001104659-22-023106 (2022-02-14) — 8-K item 5.06 "Change in Shell Company Status" (EDGAR item index, items: 1.01,2.01,3.02,3.03,4.01,5.01,5.02,5.03,5.06,9.01). 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.
