SpacBrain’s read

Floor not confirmed

No redemption window has closed — but no dated redemption election is on file for this name either, so we cannot show you a date to act by.

What we do have: no window has closed, and the deadline we compute for it runs to 24 November 2027 — our arithmetic off the IPO date and the charter term, not a date any filing we hold states. That deadline is not itself a window you can redeem into. The full chain of evidence is under Evidence.

Change on the last daily close0.0% day

That is $0.17 below the $10.12 of cash held per share as last filed — though the right to claim that cash is not confirmed on file. Against our ESTIMATE of what the trust holds today — ~$10.20, the filed figure carried forward at the T-bill — the same price is 2.4% below the cash. That estimate is our arithmetic, not a filing.


In plain terms

What it is
A $125M SPAC from ClearThink 1 Sponsor LLC, listed on Nasdaq in February 2026. Each unit put $10.00 into the shareholders' cash account at listing; it holds $10.12 a share today — interest earned on the account, plus any payments the sponsor made to extend the deadline, spread over the shares that never cashed out.
What it's doing now
It is still looking: no purchase has been announced. No filing we hold states the date it has to agree one by; our own estimate, from the IPO date and the charter term, is 24 November 2027. After that date it must ask shareholders for more time, or give the money back and close.
What you should know
We have no filed date on which you could claim the cash back, so we cannot tell you a day to act by. That is a gap in the public record, not a statement that the right has gone.

Modelled, not filed: $10.12 filed 30 June 2026, compounded 72 days at the 3.95% 3-month T-bill (treasury.gov daily par yield curve). No tax drag, extension deposits or dissolution costs are modelled.

Two denominators, one price. The filed figure is what a document says the trust held on its date; the estimate carries it forward at the T-bill for the days since, which is our arithmetic and not a filing.

Next date that matters25 November 2027

A contractual long-stop for closing a deal. It is not a redemption window and gives you no right to cash. What an outside date is →

Yield to redemption

No dated redemption window on file — no yield to compute.

We hold no redemption election for this SPAC. The only dated event on file is the outside date on Nov 25, 2027, which pays a holder nothing — so no yield can be measured to it. An unsourced date would make the yield look filed when it is not.


What is protecting this price

The reasoning behind the verdict above, in the order the filings establish it.

  1. No dated redemption election is on file for this name. That is an absence in the record, not proof that the right has gone — but it does mean this page cannot tell you a day to act by.
  2. Cash held in trust is $10.12 per share as last filed. That is the figure a redemption pays out at, plus whatever interest the trust earns between the filing and the window.
  3. The charter runs to a date no filing we hold states; from the IPO date and the charter term we estimate 24 November 2027. Whenever it falls, if no deal closes by then the trust is returned to holders — a floor of a different kind: it pays out, but you do not choose when, and this one you should read out of the prospectus yourself.

The score

deterministic, from filed fields

One number for the shape of the bet: how much upside you are getting per unit of downside. It is arithmetic over filed fields, not a rating and not advice — and it is the same number this SPAC carries on the leaderboard, the screener and the deal list, because all four read one engine.

Asymmetric return scoreThe tick is 57, the median of the 292 names scored.

1.7% below the last filed trust — floor not confirmed — no redemption election on file

The blend is trust discount (40 points), deal stage (30), sponsor track record (18) and time to catalyst (12). Every input is a real sourced field; where one is missing, confidence drops rather than a number being invented.

The company

from SEC filings
Read the full profile

ClearThink 1 Acquisition Corp. is a $125 million Nasdaq SPAC. While the company is not limited to a particular industry or geographic region, it intends to focus on the financial services sector in the United States and other developed countries. The company is headquartered in Boca Raton, Florida, and is led by Chief Executive Officer William Brock, with ClearThink Capital LLC involved in the sponsorship and management structure.

ClearThink 1 Acquisition priced its initial public offering on February 24, 2026, raising $125 million through the sale of units on the Nasdaq stock exchange under the ticker CTAA. Each unit was offered at $10.00 and consists of one Class A ordinary share and one right to receive one-fifth (1/5) of a Class A ordinary share upon completion of a business combination; the rights trade separately as CTAAR. No target has been announced, and the deadline is November 2027.


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 filing establishes the baseline trust value per share ($10.05 as stated, though the prompt notes $10.12, likely from subsequent interest) and confirms the sponsor's final share count post-forfeiture. It provides the first look at the company's operating expenses and interest income from the trust. Investors tracking redemption mechanics will note the current trust value exceeds the $10.00 IPO price, no imminent deadline (21 months from IPO, i.e., November 2027), and no redemption activity or extension solicitation. The company remains in the search phase.

  • Although the redemption calendar, trust mechanics, and search status remain unchanged, the disclosure materially defines the standalone economics of the detachable rights ahead of their Nasdaq debut under CTAAR. Because the press release confirms that fractional ownership accumulates until five rights equal one full Class A ordinary share at merger closing, investors tracking redemption pricing and arbitrage spreads must model the rights as a distinct incremental equity instrument rather than immediate voting shares. The filing also reiterates the sponsor’s stated strategy: the press release notes the company 'intends to focus on the financial services sector in the United States and other developed countries,' establishing baseline target parameters without triggering any amendment to the current SEARCHING status. Signed by Chief Executive Officer William Brock, the report introduces Ari Brown as the designated press contact and identifies D. Boral Capital LLC as the sole book-running manager of the initial public offering.

  • This filing provides the first audited financials and full disclosure post-IPO, confirming the trust account value per share, the redemption deadline, and the sponsor's low-cost stake. Investors can assess the timeline, dilution risk, and the terms under which they may redeem shares. The filing also highlights risks such as potential inability to complete a business combination within the deadline and sponsor conflicts.

  • This submission fulfills routine Section 16(a) compliance obligations and does not modify the SPAC’s redemption deadline of 2027-11-24, trust balance of $10.12 per share, or search-phase operational status. It confirms the stated magnitude of executive ownership but provides no information on target acquisition progress, extension voting mechanics, sponsor governance conduct, or shareholder redemption activity. Because Form 3 filings capture ownership snapshots rather than trade executions, they carry zero immediate impact on investor liquidation windows or deal catalysts. Monitoring subsequent Forms 4 will be necessary to detect any actual purchase, sale, or position adjustment that could signal management capital commitment or strategic intent during the remaining search period.

  • Per Note 1, management represents the Company intends to focus its search on high potential United States businesses and has not commenced operations. The balance sheet classifies 12,500,000 Class A ordinary shares at $125,000,000 as temporary equity subject to possible redemption at $10.00 per share. According to the Liquidity and Capital Resources section, management believes the Company possesses sufficient working capital to identify candidates, perform due diligence, and structure transactions through the earlier of a Business Combination completion or one year from this filing. The Combination Period spans 21 months from the IPO closing, after which the Company must cease operations, redeem 100% of Public Shares from the Trust Account, and dissolve. Per Note 5, the Sponsor waived liquidating distribution rights to Founder Shares but the filing explicitly states the Company has not verified Sponsor solvency, noting the belief that the Sponsor’s only assets are Company securities, which directly impacts the practical enforceability of the indemnification protection for the Trust Account. The partial over-allotment exercise adjusts the pro forma capital structure but does not modify the redemption mechanics, trust preservation framework, or 21-month extension conditions requiring deposits of $0.033 per share per month.

  • This filing establishes the foundational trust balance, capital structure, and timeline for CTAA. The 21-month combination window defines the deadline before mandatory liquidation, which would trigger public share redemptions at the pro-rata trust balance (initially anticipated to be $10.00 per public share, plus any pro rata interest then in the Trust Account, net of taxes payable for the Company’s franchise and income taxes or funds for working capital requirements). The $0.033 monthly extension deposit requirement and sponsor waiver provisions set the baseline economics for shareholders in a liquidation or extension scenario. The partial over-allotment exercise adjusts the post-offering share count and founder forfeiture parameters but leaves the core trust mechanism and redemption rights unchanged. Regarding other substance, management states the company intends to focus its search on high-potential businesses based in the United States, notes it has not commenced operations, and will generate non-operating income solely from interest on trust proceeds. Rights attached to units model a $0.24 fair value per right using a 24.00% combined probability, 3.45% risk-free rate, and 6.00% volatility. Auditor WithumSmith+Brown, PC issued an unqualified opinion on the February 25, 2026 balance sheet. None of these items alter the mandatory redemption floor or extension mechanics, but they confirm sponsor alignment, working capital liquidity sources, and the company’s pre-operation status as reported by management.

  • This filing establishes the initial structure and terms for all future redemption decisions: the trust has $125,000,000 (plus the over-allotment deposit), target fair market value must be at least 80% of trust assets, and the sponsor and insiders have agreed to vote their shares in favor of a business combination and not to redeem. It also details the sponsor's skin-in-the-game: 4,791,667 founder shares (after a 958,333 cancellation) purchased for $25,000 and 315,000 private units at $10.00 each, though the underwriters' overallotment option was only partially exercised. The filing includes standard sponsor conduct provisions (a 0.5% tail fee to the underwriter if the sponsor raises capital with certain investors within 12 months).

  • Establishes the SPAC's baseline mechanics: $125 million trust ($10.00 per share), 21‑month deadline, redemption rights with a 15% cap on redemptions without consent if a shareholder vote is used, sponsor founder shares at $0.005 per share, and a private placement of 315,000 units at $10.00. The improved right ratio (1/5 vs. 1/10) increases potential dilution to public shareholders. The shortened completion window removes the prior 24‑month extension option for announced deals. The auditor's report includes a going‑concern qualification. No business combination has been selected.

  • This filing locks the structural economics and timeline boundaries for public shareholders ahead of effectiveness. By specifying the exact trust deposits (US$151,930,000 or US$172,500,000) and the mechanical extension cost (US$0.33 per share monthly for up to 21 months), it quantifies the cash burden placed on non-redeeming holders should management seek extra time. The contractual requirement in Section 7.7 that a target must hold fair market value of at least 80% of trust assets establishes a valuation floor for future combinations, while the insider waivers and fixed monthly admin fees clarify sponsor alignment and recurring burn rates. Because the registrant affirmatively discloses an absence of active deal negotiations or target engagements, the document reinforces that the SPAC remains in a preliminary search phase, indicating no imminent redemption catalysts or merger timelines exist based on current management assertions.

  • The filing completes the registration statement for the IPO, providing the definitive terms of the offering and the contractual framework for the SPAC. Key details: 15,000,000 units at $10.00 per unit (plus 2,250,000 over-allotment); trust deposit of $150,000,000 ($172.5 million with overallotment); working capital of ~$1.93 million released to the company; 21-month deadline to complete a business combination (extendable by 21 additional months with $0.033 per share monthly deposits); tail fee of 0.5% to underwriter on sponsor financings within 12 months. For investors, the trust value and redemption mechanics are unchanged, but the filing confirms the sponsor's commitment and the terms of the IPO.

  • The S-1 defines the redemption mechanics (trust value $10.00 per share, 21-month deadline, possible 24-month extension with $0.033/month deposit), sponsor conduct (founder shares at $0.004, private units at $10.00, conflicts of interest), and deal progress (no target identified, no substantive discussions). Investors can now evaluate the SPAC's structure before the IPO.

  • This filing provides the first detailed disclosure of the SPAC's structure, including trust amount ($10.00 per share, though current trust per share is stated as $10.12 elsewhere), deadline mechanics, redemption terms (including the 15% cap if shareholder vote is used), sponsor economics (founder shares at ~$0.004 per share, creating significant dilution), and the intended target focus on financial services. The nominal sponsor purchase price and anti-dilution provisions are notable for potential dilution. The filing also contains extensive risk factors and management backgrounds. Investors tracking redemption deadlines and trust value should note the 24-month period from IPO and the extension provisions.

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: Quarterly report (Form 10-Q) for the period ended June 30, 2026, filed by ClearThink 1 Acquisition Corp., a blank-check company that completed its IPO in February 2026 and is still searching for a business combination target. No new deal announcement, no extension proposal, no material change in trust value per share. Sponsor advance repaid at IPO; all pre-IPO loans extinguished. The trust holds $126,658,210 as of June 30, 2026, representing $10.12 per public share (up from $10.00 at IPO due to interest income). The 21-month deadline to complete a business combination runs from the February 25, 2026 IPO closing, making the current deadline approximately November 24, 2027. The sponsor may seek a shareholder vote to extend, depositing $0.033 per share per month. Why it matters: This is a routine first-quarter filing post-IPO, confirming the SPAC is on the clock with no announced target. Trust value per share is $10.12, so there is no trust erosion. The sponsor's working capital loan facility of up to $1,500,000 is available but undrawn. The filing confirms sponsor conduct indemnification language and the combination period mechanics. The market implication is minimal: the SPAC is still in its early search phase, with no material change in redemption mechanics, trust value, or sponsor risk.

    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: This document IS a Notification of Late Filing (Form 12b-25) submitted to the Securities and Exchange Commission, formally notifying regulators that the Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2026, was not submitted within the prescribed statutory timeframe. Regarding mechanics, the filing introduces no modifications to the redemption deadline, trust account distribution value, or business combination extension schedule. CEO William Brock states the Registrant could not compile required disclosure approvals without unreasonable effort or expense, but pledges to deliver the delayed Quarterly Report no later than the fifth calendar day following the original due date. He confirms all other periodic reports mandated under Section 13 or 15(d) of the Exchange Act were filed during the preceding 12 months and indicates the company does not anticipate significant operational variances from the prior fiscal year. As a search-phase special purpose acquisition vehicle, executive leadership acknowledges only nominal ongoing activity. Why it matters: For investors monitoring redemption calendars, trust solvency, sponsor execution timelines, and merger progress, this compliance exhibit signals administrative filing delay rather than strategic milestones like a target announcement, trust extension vote, or capital raise. CEO William Brock, who signed the notification on August 17, 2026, lists telephone number (561) 358-3696 as the direct point of contact for securities staff inquiries. On substantive corporate metrics, Brock’s filing claims the Registrant was incorporated as a Cayman Islands exempted company on September 11, 2025, and that the registration statement on Form S-1 for the initial public offering received effectiveness declaration on February 13, 2026. Because of the recent charter date, he notes there is no corresponding quarterly comparative data for the period ended June 30, 2025. The document contains zero disclosed claims regarding customer concentration, revenue streams, projected market size, merger strategy, target technology, pipeline partnerships, ongoing litigation, or key executive transitions. All referenced facts derive exclusively from the chief executive’s self-reported regulatory correspondence.

  • What changed: A Schedule 13G/A joint filing agreement submitted under Rule 13d-1(k) to allow Harraden Circle Investments, LLC and Frederick V. Fortmiller, Jr. to file a single beneficial ownership statement for ClearThink 1 Acquisition Corp. The filing serves as an amendment procedural attachment to an existing 13G disclosure. It confirms the administrative arrangement between the two named parties but reports no adjustments to the SPAC’s redemption deadline, trust account balance, extension schedule, merger negotiation status, or sponsor conduct. Why it matters: For investors tracking CTAA’s SEARCHING phase, this document establishes the regulatory reporting vehicle for two affiliated stakeholders while leaving all mechanical variables unchanged. It contains no substantive claims regarding customer relationships, revenue performance, addressable market size, corporate strategy, technology development, commercial partnerships, litigation exposure, or executive personnel appointments. Because the excerpt discloses only the joint filing authorization dated 2026-08-14 and omits the accompanying schedule body that would show altered share quantities or modified investment intent, it does not advance redemption timelines, affect per-share trust accounting, or signal progress toward a business combination.

  • What changed: A Schedule 13G/A beneficial ownership report filed with the SEC, identified by file number 0000919574-26-005330 and submitted by Highbridge Capital Management, LLC. According to the provided filing text, the document contains only its title, SEC form designation, file number, and reporting holder name. It discloses no share quantities, ownership percentages, acquisition costs, transaction dates, or statements of purpose. Consequently, the filing reports nothing regarding the November 24, 2027 search deadline, extension procedures, target development, redemption mechanics, or sponsor conduct. Why it matters: As a standard regulatory disclosure tracking institutional holdings, the filing monitors capital allocation rather than SPAC corporate governance. Without attached schedules or narrative details, investors cannot determine whether Highbridge Capital Management is accumulating, maintaining, or reducing its position in CTAA. The excerpt therefore offers no signal regarding potential redemption pressure, trust account sufficiency, or strategic moves ahead of the issuer's search period expiration.

  • What changed: A Schedule 13G/A — a routine compliance exhibit and beneficial ownership report. The filing attributes the submission to Aristeia Capital, L.L.C., identifying it as an amendment to a prior ownership disclosure. It provides no specific data on share counts, percentages, acquisition timing, or transaction conditions, and therefore reports no modifications to redemption deadlines, trust account mechanics, extension procedures, or sponsor conduct. Why it matters: As a standard institutional holding update, the filing neither advances nor delays the business combination timeline, alters redemption pricing, nor indicates changes to investor protections. Because the excerpt contains no financial metrics, customer lists, partnership announcements, litigation details, or strategic directives, it carries no material impact on deal progress or trust administration.

Show the other 10 filings
  • What changed: Schedule 13G beneficial ownership report. The filing discloses that Mangrove Partners IM, LLC and Nathaniel August have registered their beneficial ownership positions in CTAA. The provided excerpt contains no statements regarding the SPAC’s target search progress, any proposed business combination, sponsor conduct, trust account adjustments, extension voting procedures, or modifications to the shareholder redemption timeline. No claims concerning customers, revenue, market size, corporate strategy, technology, partnerships, litigation, or personnel are present in the text. Why it matters: For investors monitoring redemption windows, trust valuations, extension mechanisms, deal velocity, and sponsor accountability, a standalone 13G does not trigger structural changes to a searching SPAC’s framework. Ownership accumulation reported on Form 13G signals institutional or accredited positioning relative to the company’s lifecycle, but absent accompanying proxy solicitations, trust amendment resolutions, PIPE commitments, or board nominations, the submission operates purely as a regulatory transparency instrument. It does not independently advance de-SPAC negotiations, alter the mandatory redemption calendar, or shift control dynamics until additional definitive materials are filed.

  • What changed: Quarterly report (Form 10-Q) for ClearThink 1 Acquisition Corp. for the three months ended March 31, 2026, the company's first quarterly filing since its IPO. The company completed its IPO on February 25, 2026, issuing 12,500,000 units at $10.00 per unit, and a concurrent private placement of 315,000 units to the sponsor. Net proceeds of $125,150,000 were deposited in the trust account. After the quarter end, the underwriters' over-allotment option expired, resulting in the surrender of 620,000 Class B ordinary shares, leaving 4,171,667 Class B shares outstanding. The trust account held $125,569,810 as of March 31, 2026, implying a redemption value of approximately $10.05 per public share. No business combination has been announced. Why it matters: This filing establishes the baseline trust value per share ($10.05 as stated, though the prompt notes $10.12, likely from subsequent interest) and confirms the sponsor's final share count post-forfeiture. It provides the first look at the company's operating expenses and interest income from the trust. Investors tracking redemption mechanics will note the current trust value exceeds the $10.00 IPO price, no imminent deadline (21 months from IPO, i.e., November 2027), and no redemption activity or extension solicitation. The company remains in the search phase.

  • What changed: A Schedule 13G beneficial ownership report. The filing text solely identifies Highbridge Capital Management, LLC as the reporting holder. It records no change in share quantity, voting power, acquisition target assignment, redemption volume, trust account adjustments, extension proposals, or sponsor conduct. Why it matters: Because the document contains only a regulatory title and holder name, it leaves all stated operational parameters unmodified. It contains no claims attributable to Highbridge Capital Management, LLC or the issuer regarding customer bases, revenue figures, market size estimates, strategic objectives, technology platforms, partnership arrangements, litigation status, or personnel appointments.

  • What changed: Schedule 13G beneficial ownership report. The provided text reports no adjustments to redemption windows, per-share trust balances, extension votes, business combination timelines, or sponsor fiduciary actions. Why it matters: Glazer Capital, LLC and Paul J. Glazer filed the document to disclose their equity position. The text contains no statements concerning commercial contracts, income streams, addressable markets, corporate strategy, proprietary systems, alliances, pending lawsuits, or leadership roster, indicating the filing serves purely as a standard regulatory ownership update rather than an operational or strategic disclosure.

  • What changed: Routine compliance exhibit: a Schedule 13G beneficial ownership report filed by Aristeia Capital, L.L.C. regarding CTAA. Aristeia Capital, L.L.C. submitted the filing on 2026-05-14. The provided excerpt contains only the form designation, SEC accession number, and holder name. It makes no changes to or references regarding the $10.12 trust share value, the 2027-11-24 business combination deadline, extension mechanisms, redemption triggers, target identification progress, or sponsor conduct. No updates to previously disclosed SPAC operational parameters are included in the text. Why it matters: Aristeia Capital, L.L.C. files the 13G to declare beneficial ownership meeting the Section 13(d) reporting threshold, which signals a passive institutional stance during the SEARCHING phase. Beyond establishing that the holder maintains a tracked position, the filing presents no substantive assertions about customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel. As a result, the disclosure does not shift redemption liquidity assumptions, deadline urgency, or governance risk, though it fulfills standard regulatory transparency for major shareholders.

  • What changed: This document is a Schedule 13G beneficial ownership report listing AQR Capital Management, LLC; AQR Capital Management Holdings, LLC; and AQR Arbitrage, LLC as registered holders of ClearThink 1 Acquisition securities. The filing updates the public register of institutional shareholders but discloses no numerical share counts, ownership percentages, acquisition dates, or transaction classifications. Accordingly, it introduces no alterations to CTAA’s redemption timeline, trust distribution mechanics, extension voting procedures, merger negotiation stage, or sponsor conduct metrics. Why it matters: The report confirms capital deployment into a SPAC classified in SEARCHING status, indicating institutional position-holding ahead of a potential de-SPAC transaction. The filing contains zero substantive operational disclosures, providing no information on prospective customers, contracted revenue, addressable market sizing, target acquisition strategy, proprietary technology, strategic alliances, ongoing litigation, or executive personnel movements. Without a pending business combination definition or amended charter/warrant terms, this regulatory update does not activate redemption windows or adjust trust fund expectations. Consequently, the filing registers holder composition rather than driving near-term liquidity events or valuation inflection points.

  • What changed: This filing is a Form 3—insider ownership report submitted to the Securities and Exchange Commission by director Hunt Darwin for Clearthink 1 Acquisition Corp., documenting beneficial ownership of equity securities. As documented in the submission, Hunt Darwin reported no non-derivative transactions or holdings. There is therefore no update to insider equity alignment, nor any mechanical impact on the redemption calendar, trust distribution schedule, extension window, merger progression, or sponsor conduct. Why it matters: During the SEARCHING phase, the static reporting of director Hunt Darwin’s equity position signals no near-term shift in capital commitment or managerial signaling that typically precedes a de-SPAC transaction. Beyond this routine compliance attestation, the filing contains no statements regarding target candidates, revenue projections, customer concentrations, market opportunity, proprietary technology, strategic partnerships, legal proceedings, or executive appointments.

  • What changed: A Form 8-K Current Report (Item 8.01 Other Events) accompanied by Exhibit 99.1, a press release announcing the mechanical separation of the registrant’s public units into independently tradable Class A ordinary shares and fractional purchase rights. The filing reports no adjustments to the SPAC’s redemption deadline, trust account value, extension provisions, or business combination timeline. Instead, it announces that holders of the Company’s public units (CTAAU) may elect to separate them into underlying securities commencing April 16, 2026. According to the press release attached to the filing, each public unit consists of one Class A ordinary share and one right to receive one-fifth of one Class A ordinary share. The press release further specifies that five rights will entitle the holder to receive one Class A ordinary share upon the consummation of a business combination. Units not separated will continue trading under the CTAAU ticker. The filing directs unitholders to have brokers contact transfer agent VStock Transfer LLC to execute the separation. Why it matters: Although the redemption calendar, trust mechanics, and search status remain unchanged, the disclosure materially defines the standalone economics of the detachable rights ahead of their Nasdaq debut under CTAAR. Because the press release confirms that fractional ownership accumulates until five rights equal one full Class A ordinary share at merger closing, investors tracking redemption pricing and arbitrage spreads must model the rights as a distinct incremental equity instrument rather than immediate voting shares. The filing also reiterates the sponsor’s stated strategy: the press release notes the company 'intends to focus on the financial services sector in the United States and other developed countries,' establishing baseline target parameters without triggering any amendment to the current SEARCHING status. Signed by Chief Executive Officer William Brock, the report introduces Ari Brown as the designated press contact and identifies D. Boral Capital LLC as the sole book-running manager of the initial public offering.

  • What changed: A routine compliance exhibit (SEC Form 3 insider ownership report) filed by director Yosef Milgrom for ClearThink 1 Acquisition Corp., explicitly noting that no non-derivative transactions or holdings were reported. The filing records zero changes to insider equity positions. No acquisitions, dispositions, or derivative exercises of SPAC shares or warrants are listed for the reporting director. Why it matters: As an administrative reporting instrument capturing no initial or ongoing equity positions, the Form 3 provides no visibility into sponsor commitment, anchor investor behavior, or management alignment relative to the combination window. It introduces no adjustments to the per-share trust amount, reveals no extension voting triggers, and supplies no data on potential redemptions. Investors monitoring cash flow preservation or deal-progress signals should treat this submission as a procedural null entry rather than a material development.

  • What changed: Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed by ClearThink 1 Acquisition Corp., a blank check company that completed its initial public offering in February 2026 and is still searching for a business combination target. This is the first annual report after the IPO. It confirms the IPO raised $125,150,000 in gross proceeds, with $125,150,000 deposited in the trust account (approximately $10.00 per public share). The deadline to complete a business combination is November 25, 2027 (21 months from the IPO closing). The sponsor holds founder shares and private units; the founder shares were acquired for $25,000. The report details redemption rights, sponsor indemnification obligations, and conflicts of interest. The company had no operations and reported a net loss of $46,492 from inception through December 31, 2025. Why it matters: This filing provides the first audited financials and full disclosure post-IPO, confirming the trust account value per share, the redemption deadline, and the sponsor's low-cost stake. Investors can assess the timeline, dilution risk, and the terms under which they may redeem shares. The filing also highlights risks such as potential inability to complete a business combination within the deadline and sponsor conflicts.

6 filers with a stake on file · 6 re-affirmed in the last 12 months. A stake with no amendment since is the filer’s last word on it, not proof it is still held — and percentages filed in different years are percentages of different floats, because this vehicle’s share count collapses at every redemption.

One line per filer, not per reporting person: a joint schedule names the management company, its funds and often the individual who controls them, and all of them report the same shares. Click a name for that filer’s whole footprint across every SPAC it has declared a stake in.

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 SAME 10-K states both "November 24, 2027, the last day of the completion window" and "November 25, 2027, the end of the completion window". November 25 is used because it also equals the 21-month window from the stated IPO closing; the filing contradicts itself and this is flagged rather than silently resolved. Extension mechanism: shareholder-vote, from the cited filing: "riod and we wish to further extend the date by which we must consummate our initial business combination, we may seek shareholder approval to amend our amended and restated memorandum and articles of association to extend the date by which we must consummate our initial business combination, provided we deposit an additional $0."
