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 WiMi Hologram Cloud Inc., listed on Nasdaq in February 2021.
What it's doing now
It agreed to buy MicroAlgo Inc., a central processing algorithm services 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

VENA 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

Venus Acquisition Corp was a blank-check company whose common stock traded on the Nasdaq Stock Market under the ticker VENA. The company priced its initial public offering on February 10, 2021, under SEC file number 333-251507, registering shares sold for cash. It identified itself as a blank-check company in its 424B4 prospectus and was classified under SEC SIC industry code 7371. The company completed a business combination, as established by an 8-K filed December 16, 2022 reporting a change in shell company status, and no longer files; EDGAR now lists CIK 0001800392 under the name MicroAlgo 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.

  • DEF 14A20 October 20220001829126-22-018109opens on sec.gov in a new tab

    A one-month extension is the shortest possible runway and signals a transaction closing on fumes — there is no margin if anything slips. VENA holders retain the redemption right at this vote, and the charter guarantees a full redemption within ten business days of any failure. With no extension deposit disclosed in the notice, holders who stay fund the delay without compensation.

  • DEFM14A4 October 20220001829126-22-017383opens on sec.gov in a new tab

    At 85.84% of the combined company for the sellers and 63.32% voting power for a single Majority Shareholder, VENA public holders end up with a token stake and no governance rights — controlled-company status lets the board waive independence protections. The PRC regulatory background, including the termination of consulting services and the ICP licences, is a jurisdiction risk trust cash does not carry. Redemption avoids both.

  • PREM14A3 August 20220001829126-22-015118opens on sec.gov in a new tab

    The vehicle passes to a controlling shareholder rather than a dispersed target base: WiMi already holds 73% of VIYI's voting securities and will hold 63.32% of New Venus's voting power, making it a Nasdaq "controlled company" eligible for governance exemptions. The 85.84% assumes no redemptions, excludes shares underlying IPO warrants, and gives effect to rights converting into 482,500 ordinary shares. The fee table values the 39,603,961 shares at $10.10 for a proposed maximum of $400,000,000, with the $37,080.00 fee previously paid on the Form S-4 filed June 29, 2021.

  • S-4/A1 July 20220001829126-22-014015opens on sec.gov in a new tab

    This hands control of the listed vehicle to an existing listed parent. WiMi Hologram Cloud Inc. is the legal and beneficial owner of 73% of VIYI's issued and outstanding voting securities and will effectively control New Venus by holding 63.32% of the voting power; New Venus will therefore be a controlled company under Nasdaq listing rules. The 39,603,961 shares issued to VIYI shareholders are approximately 85.84% of the post-transaction shares; 30,297,031 of them are affiliate control securities subject to resale restrictions and a lock-up, and 2,500,000 are freely tradeable.

  • S-4/A16 June 20220001829126-22-013637opens on sec.gov in a new tab

    The Explanatory Note is unusually specific about resale, and that is the fact that matters here. Of the 39,603,961 shares issued to VIYI shareholders, 30,297,031 will be held by people deemed affiliates of the post-combination company, making them control securities subject to Securities Act resale restrictions and a lock-up, and only 2,500,000 are freely tradeable without restriction. So the free float created by this deal is a small fraction of the shares registered, and an 85.84% ownership figure describes voting control rather than tradeable stock.

  • S-4/A12 May 20220001829126-22-010824opens on sec.gov in a new tab

    The aggregate offering price is exactly $400,000,000 while the share count carries eight significant figures, so the count is the derived half of that pair. Venus estimates the redemption price at approximately $10.10 at the time of the extraordinary general meeting and states it has no maximum redemption threshold in its memorandum and articles of association. The backstop changed hands during the process: on January 19, 2022 WiMi Hologram Cloud Inc. replaced Ever Abundant Investments Limited as the PIPE investor and the backstop investment rose from US$10 million to US$15 million.

  • S-4/A11 February 20220001829126-22-003502opens on sec.gov in a new tab

    The share count and the aggregate do not sit together cleanly: 39,603,961 shares at the stated 10.10 does not produce exactly $400,000,000, so at least one of the two is rounded, and the filing does not say which. The footnote also gives no measurement date — it says only that the price is the average of the high and low prices of the units, shares, warrants and rights of Venus Acquisition Corp on the Nasdaq Capital Market — so the figure cannot be tied to a trading day from this document.

  • S-4/A7 January 20220001829126-22-000580opens on sec.gov in a new tab

    The explanatory note states that the 39,603,961 shares to be issued to VIYI's shareholders equal approximately 85.84% of the post transaction ordinary shares, so the target's holders take the overwhelming majority of the vehicle and a non-redeeming public holder is left with a small slice. The price carries a gap worth noting: the footnote says the 10.10 is the average of the high and low prices of the units, shares, warrants and rights of Venus Acquisition Corp on the Nasdaq Capital Market, but names no measurement date, so it cannot be tied to a trading day from this document.

  • S-4/A23 December 20210001829126-21-016997opens on sec.gov in a new tab

    The 85.84% is the number that matters here: the target's shareholders end up with the overwhelming majority of the vehicle, so a public holder who does not redeem is left with a small share of a company whose economics are VIYI's. The fee-table price carries a defect worth noting — the footnote says it is the average of the high and low prices of the units, shares, warrants and rights of Venus Acquisition Corp on the Nasdaq Capital Market, but names no measurement date, so the 10.10 cannot be tied to a trading day from this document.

  • S-4/A6 October 20210001829126-21-011562opens on sec.gov in a new tab

    85.84% to one target's shareholders leaves Venus's own holders with a small remainder, and the resale profile is tight: of the 39,603,961 shares issued, 30,297,031 will be held by persons deemed affiliates of the combined company and are therefore control securities subject to resale restrictions and a lock-up, while only 2,500,000 are freely tradeable free of any lock-up. The fee table's $400,000,000 aggregate is a round number priced at 10.10, itself described as a blended average of Venus's units, shares, warrants and rights.

  • S-4/A3 September 20210001829126-21-009588opens on sec.gov in a new tab

    The target's shareholders take about 85.84% of the combined company, so a non-redeeming Venus holder is left with a small minority of a business they did not previously own. Of the shares issued, 30,297,031 will be held by persons deemed affiliates of the post-combination company and are therefore control securities subject to resale restrictions under the Securities Act and to a lock-up; the remainder are stated to be freely transferable. The registration price is an average of Venus's units, shares, warrants and rights on the Nasdaq Capital Market.

  • S-429 June 20210001829126-21-005732opens on sec.gov in a new tab

    The explanatory note states the outcome plainly: the 39,603,961 shares issued to VIYI's shareholders equal approximately 85.84% of Venus's post-transaction ordinary shares outstanding, so the SPAC's own holders are left with a small minority before any redemptions. The number of shares that will be held by affiliates, and therefore covered by the resale prospectus rather than freely transferable, is left blank. The $10.10 price is an average taken across Venus's units, shares, warrants and rights on the Nasdaq Capital Market.

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.

VENA — 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 7371 (Services-Computer Programming Services). The screen found it by filing SHAPE instead — S-1 2020-12-18 → 8-A12B 2021-02-08 → 424B4 2021-02-10 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts. SIC 7371 + self-described blank check in 424B4 0001213900-21-007962; 424B 0001213900-21-007962 priced 2021-02-10 under S-1 0001213900-20-043549 (file 333-251507, an offering for cash); common ticker VENA off 10-Q 0001829126-22-019444 (2022-11-21); lifecycle EXITED. The pricing prospectus was filed under SEC file number 333-251507, which belongs to S-1 0001213900-20-043549 (2020-12-18) — 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 2021-02-10). Ending PROVEN, not inferred: CLOSED per 8-K 0001829126-22-020336 (2022-12-16) — 8-K item 5.06 "Change in Shell Company Status" (EDGAR item index, items: 1.01,2.01,3.01,3.02,5.01,5.02,5.03,5.06,7.01,9.01). EDGAR now files this CIK as "MicroAlgo 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.
