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 30 April 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 close+0.3% day
That is $0.04 below the $10.06 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 — ~$10.13, the filed figure carried forward at the T-bill — the same price is 1.1% below the cash. That estimate is our arithmetic, not a filing.
In plain terms
- What it is
- A $60M SPAC from Mountain Crest (Suying Liu), listed on Nasdaq in April 2026.
- 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 30 April 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: $10.06 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.
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 Apr 29, 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.
- 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.
- Cash held in trust is $10.06 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.
- The charter runs to a date no filing we hold states; from the IPO date and the charter term we estimate 30 April 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 fieldsOne 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.
0.4% 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 filingsRead the full profile
Mountain Crest Acquisition 6 Corp. is a blank check company incorporated as a British Virgin Islands business company and headquartered at 524 Broadway, 11th Floor, New York, NY 10012, formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization, or similar business combination with one or more businesses. The company operates as a generalist with no restriction or limitation on the industry or geographic region of its target, though its prospectus notes it may pursue a business combination with a company located or doing business in the People's Republic of China. At the time of its initial public offering, the company had not identified any specific business combination target.
The company conducted its IPO on April 30, 2026, raising $60,000,000 through the sale of 6,000,000 units at $10.00 per unit, with each unit consisting of one ordinary share and one right entitling the holder to receive one-fourth of one ordinary share upon consummation of an initial business combination. Units traded on the Nasdaq Global Market under the symbol MCAHU, with ordinary shares and rights listed separately as MCAH and MCAHR, respectively. The underwriter, D. Boral Capital, was granted a 45-day over-allotment option to purchase up to 900,000 additional units. The trust account held $10.00 per public share. In a concurrent private placement, the sponsor Mountain Crest Holdings 6 LLC and D. Boral committed to purchase an aggregate of 90,000 private units (or 103,500 if the over-allotment option was exercised in full) at $10.00 per unit for $900,000 (or $1,035,000 if over-allotment was exercised in full). Prior to the offering, the sponsor and its affiliates held 2,957,143 founder shares purchased for $25,000.
The company's initial business combination deadline is 12 months from the closing of the IPO, with the ability to extend up to two additional three-month periods (for a total of 18 months) without shareholder approval, provided the sponsor or its affiliates deposit $600,000 (or $690,000 if the over-allotment option is exercised in full) per three-month extension into the trust account. The sponsor is led by Suying Liu, who serves as the company's key principal. No business combination has been announced. Mountain Crest is identified as a repeat SPAC sponsor, and the company's prospectus acknowledges that its sponsor, officers, and directors may participate in the formation or sponsorship of other special purpose acquisition companies similar to Mountain Crest Acquisition 6.
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.
This filing establishes the post-IPO baseline for MCAH: a 6,000,000-public-share trust at roughly $10.06 per share, no identified target, and almost no cash outside the trust. For shareholders tracking redemption and deal progress, the key items are the 12-month combination clock (extendable to 18 months without shareholder approval), the Sponsor's optional extension deposits, and the going-concern warning. Absent a deal or extension, public shareholders are on track for trust redemption, while the rights would expire worthless. Sponsor conduct to watch is whether it funds extensions and how it manages the sponsor loan and working capital deficit.
Sponsor-level share dispositions prior to a deSPAC closing alter alignment profiles and warrant scrutiny alongside the intact trust and unextended deadline. While routine for compliance, tracking the 385,714-share reduction against the sponsor’s 2,596,429 remaining stake helps investors assess whether internal liquidity events coincide with upcoming target announcements or indicate strategic recalibration before the 2027-04-30 maturity window closes.
This administrative decoupling does not modify the SPAC's business combination search period, which remains set to expire on April 30, 2027, nor does it change the per-share trust account value of $10.056262666666667. By splitting the composite units into tradable equity (MCAH) and derivative rights (MCAHR), the Company provides distinct liquidity channels for investors prior to any redemption deadline, extension proposal, or target acquisition vote. The separate tickers will enable independent pricing of the underlying shares and the fractional rights, which directly impacts how sponsors calculate promotion, monitor warrant/right dilution, and manage shareholder redemption expectations. The documented reliance on D. Boral Capital and Continental Stock Transfer & Trust Company establishes the institutional plumbing governing these mechanics moving forward.
Establishes baseline trust account value ($10.00 per share) and redemption deadline (12 months from May 1, 2026, i.e., May 1, 2027, extendable to 18 months). Provides initial capital structure, sponsor support, and operating deficit. Confirms the SPAC is in its searching phase with no deal progress, which is typical but informs shareholder expectations regarding timeline and potential liquidity risk.
This filing establishes the baseline trust value of $60,000,000 ($10.00 per public share), activates the redemption/liquidation calendar, and codifies the exact capital mechanics governing potential extension deposits. The independent auditor's explicit 'substantial doubt' conclusion regarding the company's ability to continue as a going concern signals that outside-trust liquidity is insufficient to cover a full year of operations, tying survival directly to sponsor funding capacity or timely deal completion. The document also locks in pre-combination control provisions (founder shares vote exclusively on director elections), clarifies that rights expire worthless upon liquidation, and confirms the sponsor's agreement to waive liquidation distributions for founder shares, shaping investor exit math and sponsor alignment.
This filing starts the redemption and deal clock for a newly listed Mountain Crest SPAC: the trust is now funded, public shareholders have redemption rights in connection with an initial business combination or amendments affecting redemption rights, the rights expire worthless if no combination is completed in time, and the sponsor/insiders have waived trust distributions on founder and private units, agreed to vote in favor of a deal, and remain subject to founder-share forfeiture if the over-allotment is not exercised in full. Investors tracking deal progress should treat the search as just beginning and watch for any extension deposits, redemption offers, or target announcements before the 12-month deadline from the May 1, 2026 closing.

This filing launches a new SPAC in the Mountain Crest series, with the same sponsor and management team led by Dr. Suying Liu. The trust value is $10.00 per unit, and the deadline is April 2027 (assuming an April 2026 closing). Investors should note the sponsor's low-cost founder shares ($0.0085 per share) create a strong incentive to complete a deal. The prospectus contains extensive risk disclosures about potential China-based targets, VIE structures, and regulatory risks, which may affect the SPAC's ability to find a suitable target. The filing is material for investors tracking redemption deadlines, trust value, and sponsor conduct.
This filing establishes the core legal and financial parameters for a new SPAC from a serial SPAC sponsor (the Mountain Crest franchise). Key terms include: a $10.00 trust value, a 12-month (extendable to 18-month) deadline, standard redemption rights, a 15% cap on redemptions by any single shareholder group if a vote is held, and a low founder purchase price creating significant potential dilution for public investors. The filing also contains extensive risk disclosures about the possibility of acquiring a PRC-based company and the associated regulatory risks, reflecting the sponsor's previous transactions with Chinese targets.
This filing marks the SPAC's transition from searching to offering securities to the public. It establishes the trust account size ($60M), per-share redemption value ($10.00), and the timeline for completing a deal. Investors can now assess the sponsor's track record (previous Mountain Crest SPACs completed deals with Playboy, Better Therapeutics, ETAO, CH-AUTO, and CUBEBIO), the incentive structure (founder shares purchased at ~$0.0085 per share creating substantial dilution risk), and the explicit risks of targeting a China-based company (VIE structures, CSRC approvals, HFCA Act delisting risk). The filing also reveals that the sponsor and underwriter D. Boral Capital will purchase private placement units, and that the sponsor may extend the deadline by depositing additional funds, but is not obligated to do so.

What changed: Routine compliance exhibit: a Joint Filing Agreement (Exhibit A) attached to a Schedule 13G/A beneficial ownership report, executed under Rule 13d-1(k). This document IS a routine compliance exhibit—a Joint Filing Agreement (Exhibit A) attached to a Schedule 13G/A—executed by Harraden Circle Investments, LLC and Frederick V. Fortmiller, Jr. (Managing Member) under Rule 13d-1(k) to consolidate their regulatory filing obligations for Mountain Crest Acquisition 6 Corp. Bearing on redemption deadlines, trust value, extensions, deal progress, and sponsor conduct: the provided text discloses no alterations to share counts, acquisition pricing, voting thresholds, or control intentions. It leaves the published 2027-04-30 search deadline untouched, does not revise the $10.056262666666667 per-share trust allocation, and offers zero commentary on extension mechanics, target pipeline velocity, merger execution status, or sponsor fee structures or behavioral shifts. Bearing on other substance: the filing contains no claims regarding customer relationships, revenue trajectories, total addressable markets, strategic roadmaps, intellectual property, supply chain partnerships, litigation posture, or personnel rotations; no chief executive, board member, or operating officer is quoted or attributed. The only verifiable data elements are the two signatory entities, the signature date of August 14, 2026, and the statutory rule cited. Why it matters: For investors monitoring MCAH’s redemption calendar, trust liquidity, extension vote probability, or sponsor track record, this exhibit delivers no actionable signal. It merely formalizes shared signature authority for box-filling purposes and deliberately omits the quantitative ownership metrics (total shares held, percentage of outstanding public stock, cost basis) that would otherwise dictate proxy contest viability, sponsorship compensation cliffs, or redemption pressure dynamics. Without a numerical amendment or an explicit statement of purpose altering past positions, it cannot trigger mandatory tender windows, force valuation resets, or indicate pivot activity. Until a successor 13D or a fully populated 13G/A surfaces share totals or activist intent, the filing remains structurally inert to your tracking framework.
What changed: Quarterly report on Form 10-Q filed by Mountain Crest Acquisition 6 Corp. for the quarter ended June 30, 2026 — its first quarterly report since inception on January 6, 2026 and its May 1, 2026 IPO — as a shell/blank-check company still searching for an initial business combination. The 10-Q states the Company has not selected any potential Business Combination target and has not, nor has anyone on its behalf, initiated any substantive discussions with any target. It closed its IPO on May 1, 2026, selling 6,000,000 units at $10.00 per unit for $60,000,000 gross proceeds, plus 90,000 private placement units, and held $60,337,576 in the Trust Account as of June 30, 2026, with redemption value approximately $10.06 per public share, subject to increase of up to an additional $0.20 per unit if the Sponsor elects to extend. The full over-allotment option expired unexercised on June 15, 2026, and 385,714 founder shares were forfeited. Cash outside the Trust Account was only $14,184, working capital deficit was $412,802, the Sponsor promissory note balance was $423,670, and management disclosed substantial doubt about the Company's ability to continue as a going concern. The Company has 12 months from the IPO closing to complete a Business Combination, with two optional 3-month extensions requiring $600,000 deposits each, for up to 18 months total without shareholder approval. Net income was $348,644 for the quarter and $305,174 since inception, driven mainly by $337,576 of Trust Account interest and a $47,300 change in fair value of the over-allotment liability. Rights convert to one-fourth of an ordinary share at Business Combination and expire worthless if the Company liquidates. Why it matters: This filing establishes the post-IPO baseline for MCAH: a 6,000,000-public-share trust at roughly $10.06 per share, no identified target, and almost no cash outside the trust. For shareholders tracking redemption and deal progress, the key items are the 12-month combination clock (extendable to 18 months without shareholder approval), the Sponsor's optional extension deposits, and the going-concern warning. Absent a deal or extension, public shareholders are on track for trust redemption, while the rights would expire worthless. Sponsor conduct to watch is whether it funds extensions and how it manages the sponsor loan and working capital deficit.

What changed: Schedule 13G beneficial ownership report filed with the Securities and Exchange Commission. The filing states that Highbridge Capital Management, LLC is a reporting holder for MCAH securities under SEC record 0000919574-26-005326. The excerpt provides no share quantities, acquisition dates, transaction purposes, or relationship disclosures. It therefore contains no updates regarding the 2027-04-30 redemption deadline, the trust account composition or value, extension proceedings, business combination targets, or sponsor conduct. Why it matters: Institutional ownership reports monitor capital allocation that could influence public float, voting leverage at a merger vote, or support for a de-SPAC transaction. Because this snippet omits share counts, pricing, and investment intent statements, it does not currently signal redemption pressure, extension viability, or deal acceleration. Future 13G/A filings disclosing additional shares or amended purpose statements would be required to evaluate whether Highbridge’s position affects liquidity thresholds or shareholder approval dynamics.
What changed: a routine compliance exhibit, specifically a limited power of attorney attached to a Schedule 13G filing. First, this document is a routine compliance exhibit detailing a limited power of attorney. Second, regarding reporting mechanics, Mizuho Financial Group, Inc., Mizuho Bank, Ltd., Mizuho Americas LLC, and Mizuho Securities USA LLC authorize Takahiro Katsura to execute Form 13G and related amendments under Section 13(d) and Section 13(g) of the Exchange Act. This administrative action satisfies ongoing institutional disclosure obligations but does not signal any modification to acquisition timing, trust liquidity distributions, extension proposals, or sponsor conduct. Third, the filing contains no substantive claims regarding customer concentration, revenue streams, total addressable market, development strategy, proprietary technology, joint venture partnerships, pending litigation, or executive succession; it only lists corporate titles for signatories Shuji Matsuura and Adam Hopkins, classifies the subsidiaries as an institution equivalent to Bank, a parent holding company, and a registered Broker-Dealer, and cites the physical offices at 1-5-5, Otemachi, Chiyoda-ku, Tokyo 100-8176, Japan, and 1271 Avenue of the Americas, NY, NY 10020, USA. Why it matters: Investors tracking redemption thresholds, warrant/stock pricing dynamics, or extension negotiations need not revise models based on this exhibit, as it functions strictly as a procedural authorization to maintain continuous Section 13 reporting by Mizuho-affiliated holders without impacting capital commitment schedules or liquidation waterfalls.
What changed: Schedule 13G beneficial ownership report containing two attached Powers of Attorney. The filing bears no impact on MCAH’s redemption deadlines, trust value per share, extension provisions, business combination trajectory, or sponsor conduct. Per the Power of Attorney dated July 8, 2026, The Goldman Sachs Group, Inc. appointed 17 specific individuals—Sadhiya Raffique, Santosh Vinayagamoorthy, D Guru Prasad, Tobi Amusan, Akash Keshari, Papa Lette, Andrzej Szyszka, Rahail Patel, Taiki Misu, Regina Chan, Abhilasha Bareja, Veronica Mupazviriwo, Sam Prashanth, Ameen Soetan, Abhishek Vishwanathan, Elizabeth Novak, and Matthew Pomfret—as authorized attorneys-in-fact to submit Rule 13f-1 and Regulation 13D-G filings on behalf of the firm. That instrument replaces a July 16, 2025 authorization, remains enforceable until July 8, 2027, and automatically lapses for any appointee who leaves Goldman Sachs or departs the relevant function before that date. By separate instrument executed on July 2, 2026, Carey Ziegler, identified as a Managing Director, granted Goldman Sachs & Co. LLC’s identical filing authority to the same roster of nominees, superseding a July 16, 2025 delegation, with validity running through July 2, 2027 or earlier unilateral revocation. Both documents stipulate New York state law governs their construction and confirm signing by Scott Kilpatrick (attired as Attorney-in-Fact) and Carey Ziegler respectively. Why it matters: As an internal administrative update governing an institutional holder’s regulatory submission logistics, the Power of Attorney carries zero implication for MCAH’s capital structure, SEARCHING status, or April 30, 2027 termination horizon. It confirms standard operational compliance by The Goldman Sachs Group, Inc. and Goldman Sachs & Co. LLC without communicating target acquisition progress, sponsorship intentions, or shifts in trust administration expectations. Investors should treat the filing as a routine custody-and-reporting housekeeping item that leaves all existing redemption windows, merger timelines, and sponsor governance parameters unchanged.

What changed: A Joint Filing Agreement attached to a Schedule 13G beneficial ownership report concerning the ordinary shares, par value $0.0001 per share, of Mountain Crest Acquisition 6 Corp. Mountain Crest Holdings 6 LLC and Suying Liu executed a written agreement to jointly file the underlying Schedule 13G statements regarding their beneficial ownership positions. The agreement stipulates that each signatory bears sole responsibility for the accuracy and completeness of their own reported holdings, while expressly disclaiming liability for the other party's disclosures absent actual knowledge of inaccuracy. This procedural alignment leaves the SPAC's redemption window, trust composition, extension posture, and target acquisition trajectory entirely unaffected. Why it matters: For investors tracking redemption deadlines, trust value, extensions, deal progress, and sponsor conduct, this document confirms routine regulatory administration rather than any strategic or financial development. The shared-filing mechanism between the sponsor vehicle and its sole manager does not alter the existing operational mandate or signal any preparatory steps toward a merger. The text contains no assertions regarding customer contracts, revenue streams, market sizing, corporate strategy, technology assets, partnership formations, active litigation, or executive personnel changes. Because it functions purely as a compliance wrapper for beneficial ownership disclosure under Rule 13d-1(k), it provides no actionable signal beyond confirming standard reporting architecture.
What changed: A Form 4 Statement of Changes in Beneficial Ownership filed under Section 16(a) of the Securities Exchange Act, functioning as a routine regulatory insider holding report. According to the filing, Liu Suying—identified as a director, CEO and CFO and a ten percent owner—disposed of 385,714 shares through an “other” transaction category on 2026-06-24. The document records her post-transaction holding as 2,596,429 shares. No amendments to merger timelines, trust account distributions, extension voting procedures, or redemption mechanics are disclosed. Why it matters: For investors tracking SPAC operations, this filing leaves the published deadline of 2027-04-30 unchanged, does not affect the stated trust/value metric of $10.056262666666667, and registers no business combination milestone or sponsorship extension proposal. Because the SEC mandates Form 4 disclosures upon any ownership shift by officers and ten percent holders, the disposition attributed to Liu Suying constitutes standard compliance reporting rather than a strategic indicator. The text contains no assertions regarding customer contracts, revenue streams, total addressable market, technology roadmap, strategic alliances, or pending litigation. The sole substantive update is the recalculated insider position, which warrants routine portfolio monitoring but does not independently trigger redemption calendar shifts or reprice the trust pool.
What changed: FORM 4 — insider ownership report. Attributed to Mountain Crest Holdings 6 LLC in the SEC filing text, the document records an other transaction on 2026-06-24 wherein the 10% owner disposed of 385,714 shares, reducing its position to 2,596,429 shares. Regarding redemption mechanics, the filing provides no updates to the trust value ($10.056262666666667 per share), the 2027-04-30 deadline, extension provisions, or deal progress; the SPAC remains in SEARCHING status. Concerning other substance, the filing contains no claims regarding customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel. Why it matters: Sponsor-level share dispositions prior to a deSPAC closing alter alignment profiles and warrant scrutiny alongside the intact trust and unextended deadline. While routine for compliance, tracking the 385,714-share reduction against the sponsor’s 2,596,429 remaining stake helps investors assess whether internal liquidity events coincide with upcoming target announcements or indicate strategic recalibration before the 2027-04-30 maturity window closes.
What changed: SEC Form 8-K current report announcing the separate trading of ordinary shares and rights from the Company's units, accompanied by a press release. Per the press release dated June 17, 2026, signed by Chairman, CEO and CFO Dr. Suying Liu, Mountain Crest Acquisition 6 Corp. announced that holders of the 6,000,000 units sold in the initial public offering may elect to separately trade the underlying ordinary shares and rights commencing on or about June 22, 2026. Separated ordinary shares will trade on NASDAQ under the symbol MCAH and separated rights under MCAHR, while unseparated units will continue trading under MCAHU. The Company stated that holders must have their brokers contact the transfer agent, Continental Stock Transfer & Trust Company, to execute the separation. The filing also confirmed that the underlying registration statement on Form S-1 (File No. 333-294891) was declared effective by the SEC on April 29, 2026, and D. Boral Capital acted as sole book-running manager of the offering. Why it matters: This administrative decoupling does not modify the SPAC's business combination search period, which remains set to expire on April 30, 2027, nor does it change the per-share trust account value of $10.056262666666667. By splitting the composite units into tradable equity (MCAH) and derivative rights (MCAHR), the Company provides distinct liquidity channels for investors prior to any redemption deadline, extension proposal, or target acquisition vote. The separate tickers will enable independent pricing of the underlying shares and the fractional rights, which directly impacts how sponsors calculate promotion, monitor warrant/right dilution, and manage shareholder redemption expectations. The documented reliance on D. Boral Capital and Continental Stock Transfer & Trust Company establishes the institutional plumbing governing these mechanics moving forward.
What changed: Quarterly report (Form 10-Q) for the period from inception (January 6, 2026) through March 31, 2026, filed by Mountain Crest Acquisition 6 Corp., a blank-check SPAC that completed its IPO on May 1, 2026. This is the first periodic report since incorporation. No operations or revenues reported. The IPO and private placement closed after the quarter end on May 1, 2026, issuing 6,000,000 units at $10.00 per unit (gross $60,000,000) and 90,000 private placement units at $10.00 (gross $900,000, with $250,000 cash and $650,000 in underwriting fees). Net proceeds of $60,000,000 were placed in the trust account, resulting in trust value of $10.00 per public share. The Company has 12 months from the IPO closing (May 1, 2027) to complete its initial business combination, with the option to extend up to an additional 6 months via sponsor deposits of $0.10 per share per extension. No target business has been identified. The Company reports a net loss of $43,470 for the pre-IPO period, cash of $30,000, and a working capital deficit of $105,420 as of March 31, 2026. Management discloses substantial doubt about going concern. Sponsor loan commitment of up to $750,000. Founder shares (2,957,143 shares) issued for $25,000, with up to 385,714 subject to forfeiture based on over-allotment exercise. Why it matters: Establishes baseline trust account value ($10.00 per share) and redemption deadline (12 months from May 1, 2026, i.e., May 1, 2027, extendable to 18 months). Provides initial capital structure, sponsor support, and operating deficit. Confirms the SPAC is in its searching phase with no deal progress, which is typical but informs shareholder expectations regarding timeline and potential liquidity risk.
What changed: A Joint Filing Agreement (Exhibit A) attached to a Schedule 13G beneficial ownership report, executed by eight affiliated Harraden Circle investment entities and Frederick V. Fortmiller, Jr., to satisfy Rule 13d-1(k) collective filing requirements. No modifications to the SPAC’s redemption timeline, trust distribution mechanics, extension vote procedures, merger negotiations, or sponsor oversight are documented. The filing exclusively records that Mr. Fortmiller, identified as Managing Member across the constituent entities, will sign subsequent amendments for the entire group on behalf of all undersigned parties as of May 7, 2026. Why it matters: Investors monitoring shareholder registry integrity and regulatory posture should note this exhibit formalizes the chain of custody for beneficial ownership disclosures across multiple limited partnerships and management companies. While the document contains zero references to prospective acquisition targets, operational metrics, customer concentrations, revenue projections, addressable market sizing, proprietary technology, commercial alliances, active litigation, or leadership transitions, establishing joint filing parameters is foundational for tracking when aggregated positions might cross disclosure thresholds. Compliance exhibits of this type do not accelerate liquidation clocks or reprice redemption yields, but they provide transparency into how affiliate funds coordinate equity reporting ahead of potential position adjustments.
What changed: Form 8-K current report announcing the consummation of Mountain Crest Acquisition 6 Corp.'s initial public offering and filing its audited balance sheet as of May 1, 2026. Per the filing, the company sold 6,000,000 units at $10.00 per unit on May 1, 2026, generating $60,000,000 in gross proceeds that were entirely deposited into a U.S.-based trust account. The report formalizes a 12-month combination period following closing, with an unapproved extension mechanism allowing two additional three-month periods financed by $600,000 ($0.10 per share) non-interest-bearing loans from the sponsor. The attached audited balance sheet and notes disclose $4,650 in external operating cash, a $428,387 working capital deficit, a $346,720 related-party promissory note, 2,957,143 founder shares purchased for $25,000, and underwriter compensation consisting of 65,000 upfront private placement units plus a deferred commitment of 150,000 shares payable at business combination. Why it matters: This filing establishes the baseline trust value of $60,000,000 ($10.00 per public share), activates the redemption/liquidation calendar, and codifies the exact capital mechanics governing potential extension deposits. The independent auditor's explicit 'substantial doubt' conclusion regarding the company's ability to continue as a going concern signals that outside-trust liquidity is insufficient to cover a full year of operations, tying survival directly to sponsor funding capacity or timely deal completion. The document also locks in pre-combination control provisions (founder shares vote exclusively on director elections), clarifies that rights expire worthless upon liquidation, and confirms the sponsor's agreement to waive liquidation distributions for founder shares, shaping investor exit math and sponsor alignment.
What changed: Form 8-K filed May 5, 2026 by Mountain Crest Acquisition 6 Corp. reporting the pricing and closing of its $60,000,000 initial public offering on May 1, 2026, the related SPAC IPO agreements, the simultaneous private placement, and the filing of amended BVI charter documents. The IPO closed: 6,000,000 units were sold at $10.00 per unit, gross proceeds were $60,000,000, and $60,000,000 of IPO and private placement proceeds were deposited into the trust account as of May 1, 2026. The Company entered into the underwriting agreement with D. Boral Capital, a rights agreement and investment management trust agreement with Continental Stock Transfer & Trust Company, a registration rights agreement, a private placement unit purchase agreement, indemnity agreements, and an administrative services agreement. The Sponsor purchased 90,000 private units for $900,000, and the Company issued 65,000 additional private placement units to D. Boral in satisfaction of part of the underwriting fee. Under the governing documents, the initial business combination period is 12 months from the closing of the Offering, with the sponsor permitted to extend twice by three months each, up to 18 months, by depositing $600,000 (or $690,000 if the over-allotment option is exercised in full) per extension. The underwriting agreement states the Company has not identified any business combination target and has not initiated substantive discussions with any target. Why it matters: This filing starts the redemption and deal clock for a newly listed Mountain Crest SPAC: the trust is now funded, public shareholders have redemption rights in connection with an initial business combination or amendments affecting redemption rights, the rights expire worthless if no combination is completed in time, and the sponsor/insiders have waived trust distributions on founder and private units, agreed to vote in favor of a deal, and remain subject to founder-share forfeiture if the over-allotment is not exercised in full. Investors tracking deal progress should treat the search as just beginning and watch for any extension deposits, redemption offers, or target announcements before the 12-month deadline from the May 1, 2026 closing.
What changed: A Form 4 statement of changes in beneficial ownership, categorized in the submission as a routine insider ownership report. The filing discloses that Liu Suying, designated in the report as director, CEO, CFO, and 10% owner, completed an open-market purchase of 25,000 shares at $10 on 2026-05-01, resulting in a confirmed post-transaction holding of 2,982,143 shares. Why it matters: Structurally, the transaction produces zero mechanical shift: the $10.056262666666667 trust/share amount, the 2027-04-30 business combination deadline, any automatic or discretionary extension windows, target acquisition pipeline, and public shareholder redemption/tender rights remain entirely unmodified. Because the shares were acquired on the secondary market rather than through subscription to or redemption from the public trust, no proceeds entered or exited the trust account, and no extension financing or warrant exercise events were triggered. Attributed solely to the SEC filing, this is a standard equity accumulation record with no embedded projections or covenants. Regarding additional substance, the document contains no statements or data concerning customer contracts, revenue streams, addressable market size, merger execution strategy, target technology or patents, commercial partnerships, pending litigation, or organizational personnel changes; those subjects are completely absent from the submission. The only extractable insight concerns sponsor conduct: the reported buying pattern indicates management deployed capital at current market levels, though the filer attaches no forward-looking obligations or operational updates to this activity.
What changed: Form 4 insider ownership report for Mountain Crest Acquisition 6 Corp., filed 2026-05-05, classified as a routine compliance disclosure tracking secondary market equity transactions. Mountain Crest Holdings 6 LLC reported executing an open-market purchase of 25,000 shares at $10 on 2026-05-01, updating its direct position to 2,982,143 shares post-transaction. This trade does not trigger any amendment to the stated 2027-04-30 redemption deadline, leaves the existing $10.056262666666667 per-share trust balance intact, and requires no extension vote or trust distribution adjustment. Sponsor conduct reflects continued capital allocation into public float without altering redemption mechanics or business combination timelines. Why it matters: Accumulation by the 10% owner during a SEARCHING phase signals operational continuity and provides baseline liquidity support while shareholders retain full redemption options. Because the shares were acquired via standard open-market execution at $10 rather than through underwriter agreements or private placements, trust accounting and investor conversion rights remain unchanged. The filing contains zero assertions regarding customer bases, recurring revenue, total addressable market sizing, strategic roadmap shifts, proprietary technology deployments, commercial partnership structuring, active litigation exposure, or executive personnel movements; all documented substance remains strictly limited to the ownership reconciliation attributable to Mountain Crest Holdings 6 LLC.

Net: 2 completed (only Playboy survives listed; Better Therapeutics bankrupt), 3 failed/liquidated/delisted — a weak operator record. Sources: SEC EDGAR submissions API (formerNames) + full-text search, efts.sec.gov. — research profile — Mountain Crest is a prolific SPAC sponsor franchise controlled by Dr. Suying Liu, who serves as chairman, CEO, and CFO across the family of vehicles. Liu holds a doctorate in corporate finance from Washington University's Olin School of Business (awarded May 2015) and previously worked as an investment strategist at J.P. Morgan Chase from July 2015 to October 2018, chief strategist at real estate investment firm Mansion Capital, and head of corporate strategy at Hudson Capital Inc. (NASDAQ: HUSN). He is based in New York and describes himself as having broad industry expertise and transaction experience across banking, investment, and real estate. The Mountain Crest vehicles are incorporated in the British Virgin Islands and target businesses in North America and the Asia-Pacific region, leveraging Liu's stated network with Asian consumer markets to help North American companies tap overseas demand. His first, Mountain Crest Acquisition Corp (MCAC), raised $57.5 million in a June 2020 IPO and merged with Playboy Enterprises (now PLBY Group, Nasdaq: PLBY) in February 2021 at a deal size of approximately $372.7 million; Liu joined Playboy's board upon closing. Mountain Crest Acquisition Corp II merged with digital therapeutics company Better Therapeutics (BTTX) in 2021. Mountain Crest Acquisition Corp III, which raised $50 million in a May 2021 IPO, merged with digital healthcare platform ETAO International (OTC: ETAOF) in 2023. Mountain Crest Acquisition Corp IV merged with Chinese auto manufacturer CH-AUTO, but that company ultimately did not list on a major exchange — a clear disappointment. Mountain Crest Acquisition Corp V, which raised approximately $69 million in 2021, has a pending merger with diagnostics company CUBEBIO. The sixth vehicle, Mountain Crest Acquisition 6 Corp. (MCAHU), priced its $60 million IPO in late April 2026, selling 6 million units at $10 each with D. Boral Capital as sole bookrunner. The de-SPAC performance across this franchise raises significant concerns. Playboy (PLBY), the flagship deal, has seen its stock collapse to approximately $1.18–$1.39 per share, a dramatic decline from the combination valuation. Several other merged entities — ETAO International and CH-AUTO — ended up trading on OTC markets rather than major exchanges, and CH-AUTO failed to list on an exchange at all. These outcomes suggest that the quality of target companies brought public through the Mountain Crest platform has been uneven at best, with multiple deals resulting in illiquid, low-priced OTC securities for investors. The pattern of merged companies failing to maintain major-exchange listings is a notable red flag for prospective investors in the sixth vehicle. Additional red flags include Liu's own share-selling activity and a governance departure. On March 28, 2023, Liu resigned from his position as managing member of the sponsor of Mountain Crest Acquisition Corp V, relinquishing…

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.

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.

Derived: 10-Q acc 0001829126-26-005916 states a 12-month completion window from the IPO closing on 2026-04-29. No filing restates it as a calendar date. Extension mechanism: automatic (sponsor may extend without a further vote), from the filings: "However, if the Company anticipates that it may not be able to consummate the initial Business Combination within 12 months, it may extend the period of time to consummate a Business Combination up to two times, each by an additional three months (for a total of up to 18 months to complete a Business Combination)."
