What changed: Quarterly Report (Form 10-Q) for M3-Brigade Acquisition VI Corp., a blank check company (SPAC) searching for a business combination target. Trust account value increased from $349.6M to $355.8M due to interest; Sponsor transferred 15,000 founder shares to new director Michael Neruda on May 14, 2026; Net income of $3.0M for the quarter; Working capital $575,898; Management expresses substantial doubt about going concern due to liquidity; No target identified or deal announced. Why it matters: The trust per share increased to $10.31, providing a modest cushion above the $10.00 redemption floor. The sponsor's transfer of founder shares to a director is routine compensation but shows ongoing governance. The going concern warning indicates the SPAC's cash burn rate may require working capital loans if no deal materializes soon. The deadline remains August 28, 2027. No extension or deal progress suggests the SPAC is early in its search.

What changed: FORM 3 — insider ownership report. The filing identifies director Michael Neruda as the reporting person and records 'No non-derivative transactions or holdings reported.' It provides no updates on redemption windows, trust account valuations, extension proposals, merger negotiations, or sponsor behavior. The text also contains no assertions regarding potential target companies, customer relationships, revenue models, addressable market sizes, proprietary technology, strategic alliances, legal proceedings, or management transitions. Why it matters: Because the Form 3 documents zero non-derivative equity movements by director Michael Neruda as of the May 19, 2026 reporting date, it does not shift capital allocation signals, voting power, or incentive alignment. Shareholders tracking MBVI will observe that your baseline parameters remain unchanged: the SEARCHING designation, the August 28, 2027 termination deadline, and the $10 trust per share metric are unaffected. Routine compliance exhibits of this type primarily satisfy periodic disclosure obligations and do not, on their own, trigger redemption windows, extension votes, or business combination timelines.
What changed: Quarterly report (Form 10-Q) for M3-Brigade Acquisition VI Corp. for the quarter ended March 31, 2026. Trust account value increased from $349,608,438 to $352,682,523 (redemption value per share from $10.13 to $10.22). Net income of $2,893,630 from interest income of $3,074,085 net of $180,455 in G&A. Cash decreased from $875,408 to $794,400. Working capital of $621,150. No borrowings under working capital loans. No business combination target identified or discussions disclosed. No change to the 24-month deadline (August 28, 2027). The Company disclosed substantial doubt about going concern. On May 14, 2026, Michael Neruda was appointed as an independent director. No other material developments. Why it matters: The filing confirms the SPAC remains in search mode with no deal progress. The trust value per share has grown to $10.22, slightly above the $10.00 IPO price, offering a modest buffer for shareholders. The going concern warning highlights limited cash outside the trust, though the sponsor has committed up to $1.5 million in working capital loans. The new independent director appointment may signal preparation for a business combination. Investors should watch for any definitive agreement or extension vote.

What changed: Form 10-K annual report for M3-Brigade Acquisition VI Corp., a pre-deal SPAC that completed its IPO on August 28, 2025. This is the company's first 10-K since inception. Trust account value grew to $349.6 million ($10.13 per share) from $345 million ($10.00 per share) due to interest income. No business combination target has been identified or discussed. The company has not engaged in any substantive discussions with any target. Management added a going concern warning that substantial doubt exists if a deal is not completed by the 24-month deadline (August 2027). No amendments to the charter, no extensions, no redemptions occurred. Why it matters: For redemption calendar: trust per-share value now $10.13, above the $10.00 IPO price, so redeeming shareholders would receive a small premium. The absence of any target discussions means the SPAC is still in early search phase with about 19 months remaining. The going concern disclosure is a standard risk factor but highlights the liquidation deadline. No extension mechanism exists in the charter; shareholders would need to approve a charter amendment to extend, which the company says it does not currently intend to seek. Sponsor continues to hold 20% of shares and 81% of private warrants; no change in sponsor conduct.
What changed: This document IS a Schedule 13G filing attachment containing duplicate Powers of Attorney executed by The Goldman Sachs Group, Inc. and Goldman Sachs & Co. LLC. Regarding redemption deadlines, trust value, extensions, deal progress, and sponsor conduct, the filing contains no provisions that alter the August 28, 2027 termination date, the $10 per-share trust allocation, or any business combination activity; it is procedurally neutral on SPAC mechanics. On other substance, the attaching entities state that they have appointed Sadhiya Raffique, Santosh Vinayagamoorthy, D Guru Prasad, Tobi Amusan, Akash Keshari, Papa Lette, Andrzej Szyszka, Rahail Patel, Taiki Misu, Regina Chan, Mariana Audeves Martinez, Asheesh Bajaj, Abhilasha Bareja, Veronica Mupazviriwo, Sam Prashanth, Ameen Soetan, Abhishek Vishwanathan, Elizabeth Novak, and Matthew Pomfret as Attorneys-in-Fact to sign Rule 13f-1 and Regulation 13D-G filings. According to the instruments, these delegations remain effective until July 16, 2026, subject to unilateral revocation or automatic termination if an appointee leaves Goldman Sachs or stops performing the relevant function. The powers were signed by Managing Director Carey Ziegler as of July 16, 2025, expressly supersede prior authorizations dated July 29, 2024, and October 1, 2024, and are governed by New York law. As confirmed by the filers, this submission exclusively refreshes routine compliance signing authority without altering ownership percentages, investment intent, or redemption eligibility. Goldman Sachs renewed its internal designations for executives authorized to sign Rule 13f-1 and Regulation 13D-G filings, replacing lists tied to July 29, 2024 and October 1, 2024 with current personnel through July 16, 2026. No changes to the SPAC’s redemption calendar, trust funding, extension posture, target acquisition pipeline, or sponsor behavior are disclosed. Why it matters: Investors monitoring redemption windows, trust maintenance, or merger timelines will find zero mechanical impact from this submission. It matters only as a housekeeping confirmation that Goldman Sachs maintains standardized proxy authority for periodic ownership reporting, which does not signal a shift in investment stance, voting power, or willingness to support an extension or business combination.
What changed: A Form 3 initial statement of beneficial ownership, classified by the SEC as a routine compliance exhibit for insider equity reporting. Nothing altered regarding the tracked mechanics. The submission lists Reporting Person Frank M. Garrison (director) against Issuer M3-Brigade Acquisition VI Corp. and explicitly states 'No non-derivative transactions or holdings reported.' Consequently, there are zero adjustments to trust share counts, sponsor equity stakes, option pools, or warrant exercises. The redemption deadline and trust account parameters remain untouched by this filing. Why it matters: While functionally empty regarding portfolio movements, a Form 3 marks the formal SEC disclosure trigger for director or officer status changes. The explicit notation that Frank M. Garrison holds or acquired no non-derivative securities on the 2025-12-12 filing date (CIK sequence 0000950142-25-003178) signals that foundational promoter shares, founder options, or direct trust-linked allocations have not yet been crystallized in public filings. For investors monitoring sponsor conduct and capital alignment during the SEARCHING phase, this confirms the absence of newly disclosed equity commitments from board leadership. Until substantive grant disclosures or amendment filings appear, the market lacks verified data on how much skin-in-the-game the founding team actually retains ahead of potential redemption pressure or extension voting.
What changed: A Form 8-K current report (Items 5.02 and 9.01) announcing the appointment of Frank M. Garrison, Jr. as an independent director, filed alongside his executed Letter Agreement (Exhibit 10.1) and Indemnity Agreement (Exhibit 10.2). The board of directors appointed Frank M. Garrison, Jr. as an independent director effective December 2, 2025, and assigned him to the Audit and Compensation Committee. According to the attached Letter Agreement, the Insider agrees to vote in favor of any proposed business combination and waive redemption rights on insider shares. The document restates the Sponsor’s indemnification undertaking: M3-Brigade Sponsor VI, LLC agrees to indemnify the company so that third-party or target claims do not reduce the Trust Account below the lesser of $10.00 per Offering Share or the actual per-share trust value at liquidation. The Letter Agreement confirms the company has a 24-month window to consummate a business combination (or a later shareholder-approved date), and that liquidation triggers a mandatory 100% redemption of public shares at a cash price equal to the aggregate Trust Account balance divided by outstanding Offering Shares, less taxes and up to $100,000 for dissolution expenses. Lock-up provisions are reaffirmed: Founder Shares cannot be transferred for one year or until the closing price equals or exceeds $12.00 per share for 20 trading days within any 30-trading day period, and Private Placement Warrants are locked for 30 days after business combination completion. The Indemnity Agreement, acknowledged by Executive Chairman Mohsin Y. Meghji, grants standard D&O expense advancement and litigation protection while explicitly waiving the director’s claims against the Trust Account. Why it matters: This filing does not extend the redemption deadline past the existing August 28, 2027 schedule, update trust account valuations, grant an extension, or provide new development on target negotiations. However, it substantively updates governance by adding an independent director to the Audit and Compensation Committee and contractually reattests to the exact economic waterfalls, sponsor backstops, and insider alignment covenants that control shareholder returns upon liquidation or deal closure. As detailed in the exhibits, the underlying capital structure remains defined by 34,500,000 public units, 8,625,000 Founder Shares, and 5,333,333 Private Placement Warrants purchased for $8,000,000 ($1.50 per warrant). Working capital facilities authorize up to $300,000 in advances for organizational and offering-related expenses and up to $1,500,000 in non-interest bearing transaction loans convertible into warrants at $1.50 each. CFO Eric Greenhaus signed the report, confirming standard operating procedures continue while the SPAC remains in its search phase.
What changed: Quarterly Report (Form 10-Q) for M3-Brigade Acquisition VI Corp. for the quarter ended September 30, 2025. This is the first quarterly report filed by MBVI since its IPO on August 28, 2025. The report details the IPO's consummation (34.5M units at $10.00 generating gross proceeds of $345.0M), the full exercise of the underwriters' over-allotment option, the private placement of 5.33M warrants to Sponsor and Cantor, and the resulting trust account balance of $346.3M. No business combination target has been selected. Net income of $1.07M for the quarter was driven by interest earned on trust investments. Why it matters: The filing confirms the SPAC's initial trust value is ~$10.04 per share (up slightly from $10.00 due to interest), that 100% of the over-allotment was exercised, and that the sponsor's 1.125M founder shares are no longer subject to forfeiture. The 24-month deadline for a business combination is August 28, 2027. The report provides an early baseline for trust valuation and sponsor economics. It also includes a fair value estimate of the public warrants ($0.456 per warrant, based on a 35% probability of a successful deal), relevant for warrant pricing.

What changed: A Schedule 13G beneficial ownership report accompanied by Exhibit 99.1, which functions as a Joint Filing Agreement executed pursuant to Rule 13d-1(k). No updates to share counts, ownership thresholds, redemption deadlines, trust value calculations, extension provisions, or business combination milestones are disclosed. The undersigned parties—M3-Brigade Sponsor VI LLC, M3-Brigade Acquisition Partners VI Corp., and Mohsin Y. Meghji—mutually acknowledge a joint filing arrangement, with Mohsin Y. Meghji designated as the authorized signatory for all three entities. This confirms administrative coordination without altering capital structure or triggering any statutory reporting triggers beyond routine compliance. Why it matters: Investors monitoring redemption windows, trust disbursement conditions, or sponsor deal execution receive no operational, financial, or timeline data from this exhibit. The agreement solely governs the logistics of future regulatory submissions; it does not signal target identification, prospectus amendments, or impending voting requirements. As a routine procedural exhibit, it maintains the stated searching status and leaves the August 28, 2027 deadline and $10 per-share trust baseline untouched until separate merger documentation, preliminary proxy materials, or trust account funding/rate updates are filed.
What changed: A Form 8-K current report and attached press release (Exhibit 99.1) functioning as a routine administrative trading notice. Mechanics: The filing states that commencing October 17, 2025, holders of MBVI units may elect to separately trade the underlying Class A ordinary shares and warrants on the Nasdaq Global Market under symbols MBVI and MBVIW, while unseparated units retain symbol MBVIU. The document specifies each unit consists of one Class A ordinary share and one-third of one redeemable warrant exercisable at $11.50 per share, noting that no fractional warrants will be distributed. Substantively, the press release discloses that the initial public offering comprised 34,500,000 units, including 4,500,000 overallotment units completed on August 28, 2025, with Cantor Fitzgerald & Co. acting as sole book-running manager. The filing does not amend the redemption calendar, adjust trust distribution parameters, or update deal progress. Why it matters: The separate listing unlocks independent liquidity pools for the equity and leveraged equity components, enabling investors to trim exposure, hedge, or rotate capital without liquidating the entire unit structure. Because the warrant strike remains fixed at $11.50 and the underlying unit composition is static, the move is purely structural. It does not accelerate the business combination search, extend the termination deadline, or alter the trust account accrual. Shareholders monitoring the path to a de-SPAC transaction will watch for separate price discovery dynamics between the common stock and warrants ahead of any potential merger announcement or shareholder vote.
What changed: A quarterly report (Form 10-Q) for a blank check company covering the pre-IPO period from inception through June 30, 2025, filed after the IPO occurred on August 28, 2025. The filing is a pre-operational shell company report. It confirms the SPAC had no business operations, no revenue, no target identified, and no substantive discussions with any target. It details the formation, the issuance of 8,625,000 founder shares for $25,000, and a pre-IPO net loss of $45,258. The filing is informational; it contains the financial statements for the period leading up to and including the IPO, which was consummated after the quarter end. Key post-balance-sheet events include: (1) the IPO of 34,500,000 units at $10.00 per unit for gross proceeds of $345,000,000; (2) a private placement of 5,333,333 warrants to the sponsor and Cantor for $8,000,000; (3) the funding of the trust account with $345,000,000 ($10.00 per share); and (4) the full exercise of the underwriters' over-allotment. The company has a 24-month completion window from August 28, 2025, to complete an initial business combination. The sponsor agreed to an indemnification obligation to protect the trust if claims reduce it below $10.00 per share. Why it matters: This 10-Q is the first periodic filing for MBVI and is critical because it establishes the starting point for the trust ($345M or $10.00 per share, with $1,895,027 in working capital outside trust) and the 24-month deadline (August 28, 2027). It confirms the standard SPAC mechanics: the trust is funded, the sponsor's 1,125,000 earnout shares are no longer subject to forfeiture since the over-allotment was exercised in full, warrants have standard $11.50 exercise and $18.00 redemption features, and the sponsor and insiders have waived redemption rights and agreed to vote all founder shares in favor of a deal. This allows investors to mark their calendars and start tracking the trust. It contains no new terms about a target deal. The document is material for tracking the trust value and the ticking clock.
What changed: A Current Report on Form 8-K announcing the consummation of an initial public offering and a concurrent private placement, accompanied by an audited balance sheet as of August 28, 2025. Per the registrant’s disclosure, the IPO closed on August 28, 2025, with 34,500,000 Units sold at $10.00 per Unit, generating $345,000,000 in gross proceeds. The underwriters fully exercised their 4,500,000 Unit over-allotment option. Simultaneously, the Sponsor and Cantor Fitzgerald & Co. purchased 5,333,333 Private Placement Warrants for $8,000,000 at $1.50 per warrant. The registrant states that $345,000,000 was deposited into a U.S.-based trust account maintained by Continental Stock Transfer & Trust Company. The 24-month Completion Window to execute a business combination now begins from this closing date. The registrant discloses that it has not selected a target nor engaged in substantive discussions with any target as of the balance sheet date. The Sponsor, officers, and directors executed a letter agreement waiving redemption rights on founder shares and agreeing to vote them in favor of a business combination. The Sponsor also agreed to indemnify the trust account if third-party claims reduce it below the lesser of $10.00 per public share and the actual trust balance at liquidation, though the registrant notes it has not independently verified whether the Sponsor has sufficient funds to satisfy those obligations. As of August 28, 2025, advances from related parties totaled $257,968, and up to $1,500,000 of working capital loans may convert into warrants at $1.50 per warrant upon business combination completion. Deferred underwriting commissions stand at $16,425,000, payable upon transaction completion. Regarding personnel and equity grants, the registrant states the Sponsor granted membership interests equivalent to 15,000 founder shares to a company director on August 28, 2025, valued at $50,745 total, or $3.383 per share, based on a third-party valuation using a 1.85% discount for lack of marketability, a 3.65% risk-free rate, and 7.5% volatility. No compensation expense was recognized because the Company determined an initial business combination is not yet probable. Why it matters: This filing transitions the SPAC from the prospectus phase into the active search phase, locking the trust balance and commencing the hard liquidation countdown. The explicit confirmation that substantive discussions have not begun signals that capital allocation remains intact, deferring dilution and extension decisions to a later stage. The registrant’s internal criteria, as stated by management, require that any target business possess a fair market value equal to at least 80% of the net trust balance (excluding deferred underwriting discounts and taxes payable on trust interest) at agreement signing. The company’s operating plan dictates zero operating revenues until post-combination, with all pre-combination activity confined to formation, IPO execution, and target identification. Financial reporting elections confirm the registrant remains an emerging growth company that elected not to opt out of the extended transition period, meaning revised accounting standards will apply when adopted by private companies rather than public peers. The contractual floor protecting the $345,000,000 trust against third-party creditor claims defines the maximum downside exposure for public shareholders should the company fail to close a deal within the defined window, while the fixed $16,425,000 deferred underwriting commission establishes a direct financial incentive for the underwriters to facilitate a future transaction.
What changed: 8-K reporting the closing of the initial public offering (IPO) of M3-Brigade Acquisition VI Corp., a blank-check SPAC, including the associated underwriting, trust, warrant, and insider agreements. The company consummated its IPO of 34,500,000 units at $10.00 per unit, raising $345,000,000 in gross proceeds, which were deposited into a trust account. Simultaneously, it completed a private placement of 5,333,333 warrants at $1.50 each, generating $8,000,000. The trust now holds $345,000,000, equating to $10.00 per public share. The deadline to complete a business combination is 24 months from the IPO closing (August 28, 2027). The sponsor and insiders executed lock-up agreements and waived redemption rights on founder shares. The board appointed Benjamin Fader-Rattner as an independent director. Why it matters: This filing establishes the fundamental SPAC mechanics: the trust value per share ($10.00), the 24-month deadline (August 2027), the sponsor's 20% founder stake (subject to forfeiture if over-allotment not fully exercised), and the lock-up periods for founder shares (1 year post-business combination) and private placement warrants (30 days post-business combination). It also sets the warrant exercise price ($11.50) and redemption triggers. For investors tracking redemption deadlines and trust value, this is the baseline for all future decisions. The underwriter, Cantor Fitzgerald, holds a deferred underwriting fee of $13.5 million (plus up to $2.925 million on over-allotment) payable only upon a business combination.
What changed: Form 424B4 Prospectus for the initial public offering of 30,000,000 units by M3-Brigade Acquisition VI Corp. The filing establishes IPO mechanics: each unit prices at $10.00 and contains one Class A ordinary share and one-third of a warrant exercisable at $11.50 per share. Gross proceeds of $300,000,000 (or $345,000,000 if the 45-day, 4,500,000-unit over-allotment is fully exercised) fund a U.S. trust account administered by Continental Stock Transfer Trust Company. Why it matters: The capitalization table creates immediate and structural dilution for public shareholders via sub-penny founder purchases, anti-dilution conversions exceeding one-for-one ratios upon future equity issuance, and potential cashless private warrant exercises. The 15% concerted holder redemption threshold structurally limits coordinated exit voting power. The 24-month absolute timeline with mandatory liquidating distributions eliminates indefinite capital maintenance risk, while the trust ring-fences principal from creditor claims except for tax releases and specified dissolution costs.
What changed: SEC Form 3 (Statement of Changes in Beneficial Ownership), specifically an initial insider ownership report. Per the submitted filing text, M3-Brigade Sponsor VI LLC is identified as a reporting person and characterized as a '10% owner', while explicitly stating that 'No non-derivative transactions or holdings reported.' There are no disclosures affecting the redemption deadline, trust per share composition, extension procedures, target search milestones, or sponsor governance actions. Why it matters: Form 3 submissions function as regulatory baselines for beneficial ownership rather than catalysts for SPAC lifecycle events. The documented absence of reported holdings or transactions indicates the sponsor’s initial equity stake has not shifted, providing no direct insight into shareholder redemption windows, trust distribution mechanics, or potential extension triggers. Tracking MBVI’s future operations will require monitoring subsequent Forms 4 for active trading, S-4 proxy statements for merger candidates, or separate amendment filings; this routine compliance exhibit does not alter investor redemption calculations or mandate immediate action.
What changed: A routine SEC Form 3 insider ownership compliance exhibit for M3-Brigade Acquisition VI Corp. The filing attributes zero non-derivative transactions or share holdings to Chief Financial Officer Eric D. Greenhaus. According to the document, there are no updates to the redemption deadline (2027-08-28), trust value ($10 per share), extension mechanisms, target selection progress, or sponsor equity distributions. The text contains no claims regarding customer concentration, revenue trajectories, addressable markets, operational strategy, proprietary technology, alliance frameworks, legal proceedings, or leadership transitions beyond identifying Greenhaus as CFO. Why it matters: This baseline Section 16 disclosure confirms the CFO currently holds no reported public equity, providing no actionable signal regarding near-term deal commitment or personal capital alignment with shareholders. It leaves the shareholder redemption window, trust account preservation protocols, and the company’s active search mandate entirely unaffected.
What changed: A Form 3 Initial Statement of Beneficial Ownership of Securities, classified as a routine Section 16(a) compliance exhibit filed with the SEC for M3-Brigade Acquisition VI Corp. The filing identifies Reporting Person Benjamin F. Rattner (director) and explicitly states 'No non-derivative transactions or holdings reported.' Consequently, there are no updated insider position figures, warrant conversions, option exercises, or sponsor/promoter equity movements recorded in this submission. The document contains no data concerning trust account balances, redemption pricing, extension votes, business combination status, or operational targets. Why it matters: For investors tracking the 2027-08-28 deadline, trust value assumptions, and extension mechanics, this Form 3 produces no schedule adjustments or capital structure changes. The zero-activity declaration confirms the director has not modified his beneficial ownership since taking office, indicating no new voting concentration, sponsor alignment shift, or early liquidity event between prior filings. Because the SPAC remains in a searching phase, the absence of reported insider trades offers no forward-looking signal on target due diligence progression, lock-up negotiations, or financing bridge activity. Additionally, the filing contains no substantive claims regarding customer relationships, revenue trajectories, addressable market size, proprietary technology, commercial partnerships, executive hires beyond the named director, or active litigation. All statements are attributed directly to the plain-text declaration within the Form 3 submission.
What changed: This document is a Form 3, classified as a routine compliance exhibit under Section 16(a) of the Securities Exchange Act, specifically an insider ownership report disclosing initial beneficial ownership positions in M3-Brigade Acquisition VI Corp. The filing explicitly states there are 'No non-derivative transactions or holdings reported' for Executive Vice President & Secretary Charles Hugh Farkas Garner. No change occurred to the stated trust value of $10 per share, the redemption deadline of 2027-08-28, the SEARCHING operational status, or any aspect of deal progress or sponsor conduct. The text contains zero claims regarding customers, revenue, market size, strategy, technology, partnerships, litigation outcomes, or personnel adjustments beyond the reporting person’s named title and affiliation. Why it matters: For investors monitoring redemption windows, trust distribution mechanics, extension votes, and sponsor alignment, this submission provides no shift in those parameters: the $10 trust structure and August 28, 2027 liquidation boundary remain untouched, and no insider accumulation is recorded. While routine Section 16 filings frequently carry no immediate mechanical impact, they establish the audited baseline for executive equity exposure ahead of any target acquisition or merger negotiation. The absence of reported holdings confirms that, at least through this filing, the identified officer has not increased economic participation in the special purpose vehicle, leaving trust dynamics and redemption timelines entirely dependent on public market activity and future sponsor announcements.
What changed: SEC Form 8-A for registration of certain classes of securities pursuant to Section 12(b) of the Securities Exchange Act of 1934. This Form 8-A registers Units, Class A ordinary shares, and whole warrants for trading on The Nasdaq Stock Market LLC, executed on August 26, 2025 by Executive Chairman Mohsin Meghji. Why it matters: The registration finalizes Nasdaq listing eligibility following the August 4, 2025 Form S-1 declaration, confirming a $0.0001 par value for Class A ordinary shares and a fixed $11.50 per-share warrant exercise price.
What changed: A Form 3 initial statement of beneficial ownership filed with the Securities and Exchange Commission, registering Chaice Christopher as Executive Vice President of M3-Brigade Acquisition VI Corp. Per the explicit language of the filing, there are no non-derivative transactions or equity holdings reported. This submission does not alter the redemption deadline, the stated trust allocation, the extension timeline, acquisition target development, or sponsor governance protocols. No mechanical adjustments to the conversion window or capital structure are indicated. Why it matters: The exhibit functions as a routine personnel registration rather than a transactional update. According to the filing, the named officer holds zero reported positions, providing no measurable signal regarding personal conviction, co-investment alignment, or impending leadership restructuring ahead of the specified deadline. There are no attributed claims regarding customer bases, revenue streams, market sizing, technology roadmaps, partnership arrangements, or litigation posture. For investors tracking redemption mechanics, trust preservation, or sponsor behavior, this filing serves as a compliance record without altering the substantive investment thesis.
What changed: A SEC Form 3 — initial statement of beneficial ownership filed by director and chief executive officer Matthew Perkal for M3-Brigade Acquisition VI Corp. The filing discloses no non-derivative transactions or holdings for Mr. Perkal. It does not modify the SPAC’s redemption calendar, adjust the trust account balance, trigger or deny an extension vote, or provide updates on business combination development or sponsor funding activity. Why it matters: For public shareholders monitoring MBVI, this submission is a standard regulatory checkpoint that confirms Mr. Perkal’s continued executive designation but offers no directional signal on redemption timing, trust preservation, or deal execution. Because Form 3 filings exclusively capture insider equity positions at the time they become subject to Section 16 reporting, the explicit notation that no non-derivative holdings or transactions are reported indicates neither additional sponsor skin-in-the-game nor a shift in control dynamics. Investors seeking metrics tied to the 2027-08-28 completion horizon, trust value per share, or merger pipeline progress will find zero incremental intelligence in this text.
What changed: A Form 3 insider ownership report filed under Section 16(a) of the Securities Exchange Act. The filing discloses that Meghji Mohsin Y, Director and Executive Chairman of the Board of Directors of M3-Brigade Acquisition VI Corp., reported no non-derivative transactions or holdings. There were consequently no changes to insider equity positions, no adjustments to the sponsor’s retained share count, and no impact on the $10 per-share trust metric or the 2027-08-28 search deadline. Why it matters: For investors tracking redemption mechanics and sponsor conduct, this zero-reporting confirms routine regulatory compliance and verifies that the Executive Chairman has not recently altered public equity exposure through standard transactions. It preserves the existing capital structure baseline, leaves the SEARCHING status and 2027-08-28 timeline unaltered, and signals no immediate directional pressure on redemption thresholds or extension voting behavior. Investors will need subsequent Forms 4 filings, proxy materials, or business combination announcements to evaluate any shift in insider alignment or deal velocity.
What changed: This filing is a SEC correspondence (a Rule 461 acceleration request) drafted by Managing Director David Batalion of Cantor Fitzgerald & Co., formally asking the Commission to advance the effective date of M3-Brigade Acquisition VI Corp.’s S-1 registration statement (filed August 4, 2025, File No. 333-289225) to 4:30 p.m. Eastern Time on August 26, 2025. As stated by Cantor Fitzgerald & Co., the correspondence makes no revisions to the SPAC’s redemption timeline, the disclosed trust-per-share balance of $10.22, or the active search deadline of 2027-08-28. Why it matters: David Batalion advises that the underwriter will distribute preliminary prospectus copies to reasonably anticipated participating dealers and declares that Cantor Fitzgerald & Co. has complied and will continue to comply with Rule 15c2-8 obligations.
What changed: A regulatory correspondence (CORRESP) submitting an acceleration request for an initial registration statement on Form S-1 under Rule 461 of the Securities Act of 1933. Chief Financial Officer Eric Greenhaus requested that the effective date for the Registration Statement filed August 4, 2025 be accelerated to 4:30 p.m. Eastern Time on August 26, 2025, or as soon thereafter as may be practicable. Why it matters: The acceleration confirms active capital markets execution by the sponsor’s leadership during the current SEARCHING phase, indicating a focus on securing liquidity through the initial offering rather than closing a business combination or requesting a trust extension. It carries no direct impact on the reported trust value of $10.22 per share or the August 28, 2027 liquidation deadline, though effectiveness would typically trigger standard IPO trust funding mechanics once priced.
What changed: Amendment No. 2 to Form S-1 (submitted as an exhibits-only filing) accompanied by an attached Underwriting Agreement between M3-Brigade Acquisition VI Corp. and Cantor Fitzgerald & Co. Mechanically, the filing attaches the definitive Underwriting Agreement governing the sale of 30,000,000 Firm Units at an offering price of $10.00 per unit, with a 45-day option for up to 4,500,000 Option Units. According to the agreement, $300,000,000 will be deposited into the Trust Account upon closing of the Firm Units, incorporating both public and private placement proceeds. The Representative retains a Deferred Underwriting Commission of 4.5% on Firm Unit gross proceeds ($13,500,000) and 6.5% on Option Unit gross proceeds (up to $2,925,000), which remains in the Trust Account and is payable only upon a Business Combination Closing; these amounts are forfeited pro-rata to public shareholders if the Company liquidates without completing a combination. Simultaneously, M3-Brigade Sponsor VI LLC purchases 4,333,333 Placement Warrants and Cantor Fitzgerald purchases 1,000,000 Placement Warrants at $1.50 per warrant for an aggregate of $8,000,000, with portions deposited into the Trust Account. The sponsor holds 8,265,000 founder shares issued for $25,000 (approximately $0.003 per share), subject to surrender of up to 1,125,000 shares if the over-allotment is not fully exercised. Approximately $1,150,000 in net proceeds will remain outside the Trust Account for working capital, while Trust interest may be released to pay corporate taxes and up to $100,000 in dissolution expenses. Why it matters: This documentation resolves execution uncertainty by formalizing underwriter compensation structures, sponsor equity lock-ups, and trust account waterfalls, directly impacting public shareholder redemption economics and liquidation recovery rates. Beyond capital mechanics, Part II Item 13 of the Registration Statement discloses total issuance expenses of $850,000.00, itemized as $500,000 in legal fees, $75,000 for Nasdaq listing and filing, $60,000 in accounting fees, $55,000 in FINRA expenses, $50,000 in printing and engraving, $40,000 each for SEC and trustee fees, $23,000 miscellaneous, and $7,000 in travel and road show costs. As stated in Representation 2.16 of the Registration Statement, the company has not selected any specific target business nor engaged in substantive merger discussions, confirming it remains in a pre-deal capital raising phase with a termination deadline of August 28, 2027. Leadership is established with Mohsin Y. Meghji serving as Executive Chairman, Eric Greenhaus as Principal Financial and Accounting Officer, Matthew Perkal as Director, and Exhibit 99.1 adding Benjamin Fader Rattner as a director nominee. Additionally, Section 7.7 of the Underwriting Agreement contractually obligates the board to acquire a target possessing a fair market value of at least 80% of the Trust Account balance at the time of signing a definitive agreement, establishing a measurable valuation threshold for any future de-SPAC transaction.
What changed: Amendment No. 1 to Registration Statement on Form S-1 (S-1/A) for a SPAC initial public offering. This amendment adds audited financial statements as of June 10, 2025 and for the period from inception (June 5, 2025) through June 10, 2025, updates the preliminary prospectus with final offering terms (30,000,000 units at $10.00 per unit, $300 million trust), includes detailed dilution and capitalization tables, and provides updated disclosures on sponsor compensation, transfer restrictions, and risk factors. Legal opinions and exhibits (underwriting agreement, trust agreement, registration rights agreement, warrant agreement) are also included or referenced. Why it matters: This filing marks a critical step toward the SPAC's IPO effectiveness. It provides potential investors with the first audited financials, clarifies the trust structure, redemption terms, and deal timeline (24-month deadline). It finalizes the economics for sponsors, founders, and public shareholders, including dilution scenarios and sponsor profit incentives. The document enables investment decision-making ahead of the public offering.
What changed: A Securities and Exchange Commission correspondence (CORRESP) transmitting Amendment No. 1 to the Company’s Registration Statement on Form S-1, filed by Paul, Weiss, Rifkind, Wharton & Garrison LLP on August 18, 2025, to formally submit the Company’s written responses to SEC Staff comments received on August 14, 2025. The Company acknowledged four Staff comments and revised disclosure across pages 2, 18, 24, 81, 102, 112, 113, and 172. Why it matters: Mechanics of redemption thresholds, trust preservation, extension viability, deal progress, and sponsor conduct turn on a disclosed alignment gap: the Company states through its website that neither M3 Partners nor Brigade functions as a sponsor or manager and carries no responsibility or liability for the SPACs, yet the SEC Staff required explicit verification of whether their operational backing is paid or contractually guaranteed.
What changed: SEC Division of Corporation Finance comment letter regarding M3-Brigade Acquisition VI Corp.'s August 4, 2025 Form S-1 registration statement, directed to Executive Chairman Mohsin Y. Meghji. Why it matters: The filing does not modify the August 28, 2027 search deadline or the $10.22 trust per share, but it directly targets sponsor conduct mechanics, founder share dilution pathways, and off-balance-sheet service arrangements from M3 Partners and Brigade. If the registrant amends as requested, investors will gain visibility into potential compensation for non-sponsor support, governance continuity if the lead sponsor exits, and dilution exposure from Rule 462(b) sizing adjustments.
What changed: An SEC correspondence (CORRESP) submitting revised responses to staff comments on a confidential Form S-1 registration statement filed on behalf of M3-Brigade Acquisition VI Corp. Outside counsel Paul, Weiss, Rifkind, Wharton & Garrison LLP reported that the Company amended its registration statement after receiving fourteen comments from the SEC Staff dated July 29, 2025. Why it matters: These regulatory adjustments directly map the liquidity windows, capital constraints, and governance watchpoints that public shareholders will face before pricing and deal sequencing. Locking in redemption thresholds for fifteen percent block holders and publishing extension frequency caps tells investors precisely when redemption notices must be tendered and how long the SPAC can delay without triggering a liquidation vote.
What changed: S-1 registration statement (preliminary prospectus) for the initial public offering of M3-Brigade Acquisition VI Corp., a blank check company (SPAC) formed to effect a business combination, with no target selected. This is the initial S-1 filing. It establishes all terms of the IPO: 30,000,000 units at $10.00 per unit (each unit: one Class A ordinary share + one-third warrant), underwriter over-allotment option for 4,500,000 additional units. Trust will hold $300 million ($345 million if over-allotment exercised) at $10.00 per share. Deadline: 24 months from closing (may be extended up to 36 months with shareholder vote and redemption rights). Founder shares (8,625,000 Class B) purchased for $25,000 (~$0.003/share), representing 20% of post-offering shares. Sponsor and Cantor commit to purchase 5,333,333 private placement warrants at $1.50/warrant ($8 million total). Twenty-one non-managing sponsor investors expressed interest to purchase 4,000,000 private placement warrants indirectly and receive 3,000,000 founder shares. Public shareholders have redemption rights with a 15% aggregate limitation. Business strategy targets cryptocurrency and blockchain sectors with enterprise value of at least $1 billion. Management team has prior SPAC experience (some successful, one liquidated). Why it matters: This filing provides all structural, financial and governance terms of a new SPAC IPO. Investors need to understand the $10 trust value, 24-month deadline (extendable to 36), redemption mechanics, dilution from founder shares and private placement warrants, sponsor incentives, and the team’s track record. The focus on cryptocurrency/blockchain sectors and the inclusion of non-managing sponsor investors (21 institutional investors) are notable. The S-1 is the foundational document for evaluating the SPAC's potential and risks.
What changed: SEC Division of Corporation Finance comment letter reviewing a draft Registration Statement on Form S-1 for M3-Brigade Acquisition VI Corp. This document is an SEC Division of Corporation Finance regulatory review letter addressing a draft S-1 submitted July 2, 2025. Why it matters: According to the SEC Division of Corporation Finance, these mandatory amendments will dictate the final prospectus terms before the IPO declares effective, directly controlling how public shareholders experience dilution from converting working capital warrants, how trust liquidity is structured relative to Nasdaq listing standards, and what governance conflicts surround M3 Partners, Brigade, and Fifth SPAC affiliations.
What changed: A preliminary Form S-1 registration statement and prospectus for the initial public offering of 30,000,000 units. This filing establishes the foundational mechanics for MBVI’s pending IPO rather than reporting post-issuance operational updates. It locks in a $10.00 per-share trust deposit ($300 million total), enforces a strict 24-month completion window, and dictates that any shareholder-approved extension automatically triggers fresh redemption rights. Why it matters: The structural setup creates an intense incentive alignment where the sponsor’s nominal equity stake becomes worthless upon a missed 24-month deadline, potentially pressuring management to accept mispriced or under-diligenced targets to avoid liquidation. The explicit documentation of officers' split loyalties across several competing SPACs and corporate boards signals a material risk of divided attention, meaning search timelines may slip and extension mechanisms will become critical governance tools.
What changed: This filing is a confidential draft registration statement letter (DRSLTR) transmitted by Raphael M. Russo of Paul, Weiss, Rifkind, Wharton & Garrison LLP to the Securities and Exchange Commission’s Division of Corporation Finance on July 1, 2025. On behalf of M3-Brigade Acquisition VI Corp., the letter formally submits a draft Form S-1 for non-public review under Title I, Section 106 of the Jumpstart Our Business Startups Act of 2012 to register an underwritten offering of units consisting of common stock and warrants. No tracked SPAC mechanics shift. The cover letter contains zero disclosures regarding trust account balance per share, shareholder redemption pricing or thresholds, board extension proposals, target acquisition progress, or sponsor conduct metrics. It identifies only the participating legal contacts—Charles Garner at the Company, David Huntington at Paul, Weiss, and Stuart Neuhauser at Ellenoff Grossman & Schole LLP—and confirms the confidential routing status of the draft prospectus ahead of any public filing. Why it matters: The submission signals that M3-Brigade’s outside counsel is drafting or amending a public equity and warrant registration statement, a step that typically precedes a definitive merger agreement, a concurrent PIPE capital raise, or post-business combination liquidity mechanics. Because the document operates under JOBS Act Section 106 confidentiality, no offering size, price range, use-of-proceeds allocation, or redemption-triggering provisions are visible. Until the public filing date is declared and SEC comment rounds conclude, the timing and structure of any future cash infusion or deal validation remain opaque. Investors should monitor for the eventual prospectus issuance to determine whether the proposed unit composition, warrant exercise terms, or anticipated capital deployment interact with existing liquidity windows, warrant coverage ratios, or any implicit pressure to complete a business combination before the sponsor’s remaining calendar expires.
