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 Mach FM Acquisitions LLC, listed on Nasdaq in March 2022.
What it's doing now
It agreed to buy Solidion Technology 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.

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.

The score

deterministic, from filed fields

NUBI 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

Nubia Brand International Corp. was a Delaware-incorporated blank-check company headquartered at 13355 Noel Road, Suite 1100, Dallas, Texas, that completed its initial public offering on March 14, 2022, with its common stock trading on Nasdaq under the ticker symbol NUBI. The offering was conducted under SEC registration statement File No. 333-261114, originally filed as an S-1 on November 16, 2021, with the pricing prospectus filed as a Form 424B4 on the IPO date. Each unit consisted of one share of Class A common stock and one-half of one warrant, with each whole warrant entitling the holder to purchase one share of Class A common stock. The sponsor of the vehicle was Mach FM Acquisitions LLC, and the company's chief executive officer and director was Jaymes Winters, with Vlad Prantsevich serving as director and chief financial officer.

The company's business combination closed on February 8, 2024, as evidenced by an 8-K filing reporting a "Change in Shell Company Status" under Item 5.06, at which point EDGAR reassigned the registrant's SIC classification from 6770 (blank-check) to 3690 (Miscellaneous Electrical Machinery, Equipment & Supplies) and the entity subsequently operated under the name Solidion Technology Inc., trading on Nasdaq under the symbol STI. Following the combination, Solidion Technology positioned itself as an advanced battery technology solutions provider, developing platforms including its patented Generation Extreme-Climate Battery (Gen-ECB) technology engineered for satellites, LEO-based AI data centers, crewed spacecraft, and lunar infrastructure applications, as well as its PEAK Series UPS battery system designed for AI data centers. In June 2026, Solidion completed a $35 million private placement involving 750,000 shares of common stock and pre-funded warrants to purchase 1,583,000 shares, priced above market under Nasdaq rules, with proceeds earmarked to commercialize the Gen-ECB platform, expand inventory, advance prototype development, and support general working capital needs.


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 going-concern doubt is stated as alleviated on the strength of a completed financing, not of operations: quarterly sales are $124,914 against a $2.9 million net loss. The elimination of the Series C and D pre-funded warrants removes a derivative liability and a source of future dilution as the company describes it.

  • ...

  • Concurrently the parties stipulated to dismiss with prejudice Meteora Capital Partners, LP v. Solidion Technology (Del. Ch. No. 2024-0752-LWW, filed July 16, 2024, with a default judgment motion of August 13, 2024), with the company issuing 12,393,002 shares to Seller within five business days and paying up to $65,000 of Seller's fees. Seller forbears from Valuation Date Events only until December 31, 2024, after which its rights revive in full. The company also amended a consulting agreement with Arbor Lake Capital, paying 2,000,000 shares as a retainer plus revenue-share fees.

  • The second director departure in three weeks at a company carrying three open Nasdaq deficiencies, and the seat is filled by reassigning a sitting director rather than adding a new independent one, so board size falls. Registrant is the post-combination company Solidion Technology, recorded here under the SPAC ticker NUBI.

  • Three separate deficiencies are now open against the same company on the Nasdaq Global Market: the August 1, 2024 minimum bid price notice with a January 28, 2025 cure date, plus these two expiring February 24, 2025. The company states it will monitor and consider options but names no plan.

  • A board departure eleven days after the company received the Nasdaq minimum bid price deficiency notice. No successor is named and no committee assignments are described. Registrant is the post-combination company Solidion Technology, recorded here under the SPAC ticker NUBI.

  • A second 180-day grace period is available only by applying to transfer to the Nasdaq Capital Market, meeting that market's other initial listing standards, and giving written notice of intent to cure by a reverse stock split if necessary. Stockholders already authorised a 1-for-10 to 1-for-50 reverse split on June 3, 2024, though the company states no decision on a response has been made.

  • The periodic-filing deficiency reported five weeks earlier is cured and closed, with no compliance plan or hearing needed. Registrant is the post-combination company Solidion Technology, recorded here under the SPAC ticker NUBI.

  • The 68,055,000 votes cast are stated as 78.31% of shares outstanding and were unanimous on all three proposals, so the board holds authority to set a reverse split ratio anywhere in a 1-for-10 to 1-for-50 range without a further vote. The company states its securities continue to trade on the Nasdaq Global Market under the symbol STI. Registrant is the post-combination company Solidion Technology, recorded here under the SPAC ticker NUBI.

  • The proxy is explicit about the second-order effect: because the number of authorized shares of capital stock does not change in a reverse split while issued and outstanding shares fall in proportion to the final ratio, the split effectively increases the pool of authorized but unissued common stock available for future issuance. Holders approving both items therefore create headroom as well as compress the count — and the warrant approval is what fills that headroom.

  • A $700 million valuation delivered in roughly 70,000,000 shares prices the target at $10.00 per share, the same reference SPAC holders paid into trust — so NUBI public holders are buying an unproven battery business at par while the sellers take nearly the whole share count. The unreleased G3 tax lien is a disclosed liability being carried into the combined company, adjusted for by only $2,000,000. Redemption at trust value avoids both.

  • The earnout is unusually large and priced well above the deal: up to 22,500,000 additional shares of Class A common stock, in tranches of 5,000,000 at a volume weighted average price of $12.50, 7,500,000 at $15.00 and 10,000,000 at $25.00, each measured over any ten trading days within any thirty-trading-day period. Because the per-share consideration is blank, a Nubia holder cannot tell from this document how much of the company the $700,000,000 buys — only that 22,500,000 shares can be issued on top of it.

Everything this company has filed with the SEC recently, newest first, each with a plain summary of what changed and why it matters.

  • What changed: Exhibit 99.1 to an 8-K of Solidion Technology Inc. (Nasdaq: STI): an August 6, 2026 press release reporting Q2 2026 results. Cash and equivalents were $27.7 million at June 30, 2026 versus $0.2 million at December 31, 2025, and the company states that following completion of a $35 million private placement the previously disclosed substantial doubt about its ability to continue as a going concern has been alleviated. Why it matters: The going-concern doubt is stated as alleviated on the strength of a completed financing, not of operations: quarterly sales are $124,914 against a $2.9 million net loss. The elimination of the Series C and D pre-funded warrants removes a derivative liability and a source of future dilution as the company describes it.

    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: Solidion Technology, Inc., successor to Nubia Brand International Corp, rescheduled its first annual meeting of stockholders following the effectiveness of its amended and restated certificate of incorporation to September 15, 2026, after closing a previously announced private placement. The company set July 9, 2026 as the deadline for stockholder proposals to be included in the proxy materials under Exchange Act Rule 14a-8, and states proposals received after that date will be considered untimely. Why it matters: The date that matters here is the July 9, 2026 proposal deadline rather than the meeting itself: it is the point after which a stockholder loses the right to put a proposal into the company's own proxy materials. The record date, time and location of the meeting are not yet set and will appear in the proxy statement.

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.

The screen found it by filing SHAPE instead — S-1 2021-11-16 → 8-A12B 2022-03-10 → 424B4 2022-03-14 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts.

The pricing prospectus was filed under SEC file number 333-261114, which belongs to S-1 0001213900-21-060013 (2021-11-16) — 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 2022-03-14). Ending PROVEN, not inferred: CLOSED per 8-K 0001213900-24-011711 (2024-02-08) — 8-K item 5.06 "Change in Shell Company Status" (EDGAR item index, items: 1.01,2.01,2.03,3.02,3.03,5.01,5.02,5.03,5.05,5.06,9.01). 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.
