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 1 May 2028 — 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-0.1% day

That is $0.16 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 — ~$10.14, the filed figure carried forward at the T-bill — the same price is 2.3% below the cash. That estimate is our arithmetic, not a filing.


In plain terms

What it is
A $200M SPAC from CH4 Natural Solutions Acquisition Sponsor LLC, listed on NYSE in May 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 1 May 2028. 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.

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

Next date that matters4 May 2028

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 May 4, 2028, which pays a holder nothing — so no yield can be measured to it. An unsourced date would make the yield look filed when it is not.


What is protecting this price

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

  1. No dated redemption election is on file for this name. That is an absence in the record, not proof that the right has gone — but it does mean this page cannot tell you a day to act by.
  2. Cash held in trust is $10.06 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.
  3. The charter runs to a date no filing we hold states; from the IPO date and the charter term we estimate 1 May 2028. Whenever it falls, if no deal closes by then the trust is returned to holders — a floor of a different kind: it pays out, but you do not choose when, and this one you should read out of the prospectus yourself.

The score

deterministic, from filed fields

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

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

1.6% below the last filed trust — floor not confirmed — no redemption election on file

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

The company

from SEC filings
Read the full profile

CH4 Natural Solutions Corporation is a $200 million NYSE SPAC led by David Leuschen, hunting for real-asset businesses positioned to benefit from large-scale methane mitigation. The company stated its intent to search for a target business with a significant real-asset footprint that may provide opportunities for attractive risk-adjusted returns and benefit from accelerated methane mitigation initiatives at scale. As of the date of its prospectus, the company had not selected any business combination target and had not initiated substantive discussions with any potential target.

CH4 Natural Solutions priced its initial public offering on May 1, 2026, raising $200 million through the sale of 20,000,000 units at $10.00 per unit on the New York Stock Exchange under the symbol MTNE.U. Each unit consisted of one Class A ordinary share and one-half of one warrant, with each whole warrant exercisable to purchase one Class A ordinary share at $11.50 per share beginning 30 days after completion of an initial business combination and expiring five years thereafter. Upon separate trading, the Class A ordinary shares and warrants trade under the symbols MTNE and MTNE.WS, respectively. The underwriters, led by Santander US Capital Markets LLC as sole book-running manager, were granted a 45-day over-allotment option for up to 3,000,000 additional units. Of the offering proceeds, $200.0 million ($10.00 per unit) was placed in a U.S.-based trust account at J.P. Morgan Chase Bank, N.A., with Continental Stock Transfer Trust Company as trustee. The company's sponsor, CH4 Natural Solutions Acquisition Sponsor LLC, purchased 200,000 private placement units at $10.00 per unit ($2.0 million aggregate) in a concurrent private placement and held 7,666,667 Class B founder shares, with David Leuschen owning 100% of the economic interests in the sponsor entities and serving as Chief Executive Officer.

The company has 24 months from the closing of the offering to consummate an initial business combination, after which it must redeem 100% of public shares at the per-share trust amount if no combination is completed and no extension is approved by shareholders. No business combination has been announced.


Material findings

from the full read of every filing

Every document this company files gets read whole — body and exhibits. These are the ones the read flagged as material, newest first, each citing its filing.

  • This filing establishes the baseline mechanics and financial condition of the SPAC post-IPO. Key numbers for investors tracking redemption and deal timelines: trust value is $221,233,834, implying approximately $10.06 per share on 22,000,000 public shares. The deadline to complete an initial business combination is 24 months from the IPO (May 4, 2028). The sponsor now holds 7,333,334 founder shares. The company has $1,447,919 in cash outside the trust but a working capital deficit of $729,647, and management has flagged substantial doubt about its ability to continue as a going concern without additional sponsor support, which is a material risk for deal completion timelines.

  • This is the first quarterly report since the IPO, establishing the trust account size ($220 million), the per-share trust value ($10.00 per public share), and the 24-month deadline (May 2028). The sponsor's surrender of founder shares aligns insiders with public shareholders. The amended promissory note reduces financial flexibility. The going concern disclosure highlights risk if a target is not found quickly. For redemption calendar tracking, the trust is now funded and the deadline clock is running.

  • For investors monitoring redemption mechanics, this filing fixes the post-over-allotment trust floor at $220,000,000 across all 22,000,000 redeemable shares, establishing the maximum cash pool available for shareholder redemptions pending a business combination. The explicit $10.00 per-share redemption valuation provided by the company eliminates ambiguity around trust distribution ratios and confirms full over-allotment funding before entering the operational spending phase. The large advisory and deferred underwriting fee obligations ($6,600,000 each) and $(13,848,919) shareholder deficit underscore the capital deployment trajectory toward the May 1, 2028 deadline, while the absence of any merger target, extension resolution, or sponsor conduct disclosures leaves the SEARCHING mandate entirely unadvanced in this submission. No commercial metrics, customer claims, revenue projections, partnership announcements, litigation updates, or executive changes appear in the filing; all disclosed figures and structural mechanics derive solely from the company’s own prospectus-based reporting and CFO certification.

  • Anchors the post-IPO trust baseline that dictates per-share redemption pricing and frames the 24-month business combination window opening May 4, 2026. Quantifies the expanded deferred underwriting liability and fixed advisory commitment that reduce net capital available for acquisitions, while the sponsor’s share surrender recalibrates potential post-deal dilution ahead of any extension vote. The auditor’s liquidity disclaimer signals reliance on continued sponsor financing, and the explicit lack of target discussions confirms the search phase remains open, preserving shareholder redemption rights through the statutory period.

  • This filing establishes the trust structure and redemption mechanics for the SPAC. The trust holds approximately $10.06 per public share (including interest). The deadline to complete a business combination is 24 months from the closing, i.e., by May 2028. The sponsor and insiders have agreed to lock-up provisions and to vote in favor of any business combination. The filing confirms that the SPAC is now funded and operational, with $200 million in trust plus sponsor capital, searching for a target in methane mitigation/real assets. No redemption rights are triggered as this is the IPO closing, not a deal vote.

  • This is a new SPAC IPO with a sponsor that has a notable but mixed track record (Riverstone-affiliated). The trust value is standard at $10.00 per share. The 24-month deadline is typical. The sponsor's low cost basis creates a strong incentive to close a deal. The going-concern opinion signals that the SPAC needs the IPO to survive. The focus on methane mitigation and real assets may appeal to certain investors. The litigation history of the sponsor (Leuschen and Tepper named in lawsuits related to prior SPAC mergers) is a risk factor. The 15% redemption limit could affect shareholder rights. Overall, the filing provides full disclosure of the SPAC's terms and risks.

  • The filing does not alter any redemption deadline, shift the trust per-share amount, extend the search period, accelerate deal progression, or reflect a change in sponsor conduct. It simply establishes a director-level baseline showing zero direct economic exposure. Beyond the officer title and the single disclosed figure of 0 shares, the document contains no claims or projections regarding customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel. All information originates exclusively from the regulatory filing itself and requires no independent verification of market conditions or corporate performance.

  • Provides the final terms of the $200 million IPO (20 million units at $10.00), including trust per share of $10.00, 24-month deadline, sponsor compensation, dilution, redemption rights, and risk factors. Investors should note the sponsor's nominal cost basis ($0.003 per share) and the significant dilution to public shareholders. The filing also discloses ongoing litigation involving the CEO and director nominee.

  • The amendment is a procedural step toward declaring the registration statement effective and completing the $200 million IPO (plus up to $30 million over-allotment). The founder share surrender reduces the sponsor's ownership percentage and adjusts the capital structure, lowering potential dilution from founder shares. The going concern qualification highlights the SPAC's need for the IPO proceeds to continue operations. The inclusion of final exhibits signals the offering is near pricing. The trust will hold $10.00 per public share (approximately $200 million), and the sponsor has committed to purchase $2 million in private placement units. The SPAC has 24 months from closing to complete a business combination, with a focus on methane mitigation opportunities. No target business has been identified.

  • Ex-10.3 confirms sponsor and insiders will vote founder shares in favor of a business combination and not redeem those shares. Ex-10.4 formalizes the trust agreement for the proceeds ($300M base, $345M with over-allotment). Ex-10.6 shows the sponsor acquired 11.5M founder shares for $25,000. Ex-10.7 shows the private placement of 200,000 units for $2,000,000 ($10.00 per unit). Ex-10.3 and Ex-10.8 contain standard waivers of claims against the trust account. These standard SPAC exhibits confirm a pre-IPO structure with no deal announced.

  • This filing launches a new SPAC vehicle—a clean slate with $300M trust at $10.00/share, 24-month deadline (27-month with LOI). The sponsor team has extensive de-SPAC experience but also significant litigation baggage (Hyzon, Alta Mesa, Solid Power, Tritium). The structure is standard (founder shares at $0.002, 25% anti-dilution, 15% redemption cap). Investors should note the sponsor has changed its managing entity to RSE and the net tangible book value at maximum redemption is only $0.43, indicating extreme dilution risk.

  • This filing provides the complete prospectus for the IPO, including trust mechanics, redemption rights, sponsor economics, and risk factors. It is the key document for investors to evaluate the SPAC before the IPO. Notably, it discloses significant litigation history involving the sponsor's prior SPACs (Alta Mesa, Hyzon, Solid Power, Tritium) which may affect investor confidence. The trust per share is $10.00, and the deadline is 24 months from IPO closing. The document also includes the sponsor's agreement to indemnify the trust for third-party claims reducing trust below $10.00 per share. The IPO is underwritten by Citigroup.

  • The filing establishes the trust value at $10.06 per share and the redemption mechanics for a new SPAC with a long deadline. It also provides an unusually detailed history of the sponsor's prior de-SPAC transactions, including bankruptcies (Alta Mesa, Tritium DCFC), settlements (Hyzon-related lawsuit reached settlement in principle, Alta Mesa class-action settlement motion filed January 6, 2025), and ongoing litigation (Solid Power). This record is directly relevant for investors evaluating sponsor conduct and the risk of future deal outcomes. The document also states the sponsor group (David Leuschen, Impact Ag, Lauren Singer) intends to search for a target with a 'significant real-asset footprint' and methane mitigation focus but has not initiated any substantive discussions with any target.

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

  • What changed: Form 10-Q (unaudited quarterly report) for the period ended June 30, 2026, filed by CH4 Natural Solutions Corporation (MTNE), a blank-check company searching for an initial business combination. This is the first 10-Q filed after the Company's IPO (consummated May 4, 2026) and over-allotment exercise (May 8, 2026). The filing reports the completion of a $220 million IPO (22,000,000 units at $10.00), placing $220,000,000 (including $6,600,000 deferred underwriting fees) into the trust account. The trust held $221,233,834 at period end, reflecting $1,233,834 of interest income. The over-allotment option expired on June 15, 2026, with the underwriter forfeiting rights to the remaining 1,000,000 units, resulting in the sponsor forfeiting 333,333 Class B founder shares. The company reported a net loss of $5,894,317 for the six months, largely driven by $7,128,151 in general and administrative expenses. Management disclosed a going concern uncertainty, stating working capital is insufficient for at least one year from the filing date. Subsequent to quarter end, the company paid $300,000 to the CEO to satisfy a promissory note and made a $400,000 payment to a sponsor affiliate. Why it matters: This filing establishes the baseline mechanics and financial condition of the SPAC post-IPO. Key numbers for investors tracking redemption and deal timelines: trust value is $221,233,834, implying approximately $10.06 per share on 22,000,000 public shares. The deadline to complete an initial business combination is 24 months from the IPO (May 4, 2028). The sponsor now holds 7,333,334 founder shares. The company has $1,447,919 in cash outside the trust but a working capital deficit of $729,647, and management has flagged substantial doubt about its ability to continue as a going concern without additional sponsor support, which is a material risk for deal completion timelines.

    Read from stored SEC filing text by a regex — no model is involved — and each side links to the filing it came from. “Not previously extracted” is a statement about our record, not about the company: the clause may be present in wording we do not match.

  • What changed: A routine compliance exhibit identifying a Schedule 13G beneficial ownership report. The filing lists five entities and an individual—CH4 Natural Solutions Acquisition Sponsor LLC, CH4 Natural Solutions Acquisition Sponsor Holdings, LLC, CH4 Natural Solutions Acquisition Sponsor Manager, LLC, Riverstone Earth LLC, and David Leuschen—as joint filers. It does not move the redemption window, touch the $10.06 trust value per share, propose a deadline extension past 2028-05-01, or indicate target negotiation progress. Why it matters: For investors tracking governance and deal timelines, the filing confirms that the acquisition vehicle and its managerial principals remain jointly registered for equity purposes without disclosed share transfers or control shifts. The document makes no claims about customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel. Its only substantive takeaway is regulatory confirmation of sponsor continuity during the searching phase, which neither triggers redemptions nor advances business combination metrics.

  • What changed: A Schedule 13G beneficial ownership report (Accession Number 0000312069-26-000208) identifying Barclays PLC as the reporting holder. The excerpt discloses only the form classification and the filer name. It contains no share counts, acquisition dates, or ownership percentages to indicate a positional shift. Bearing on SPAC mechanics, the text reports zero activity regarding the 2028-05-01 redemption deadline, the $10.06 trust-per-share balance, extension proposals, deal progress, or sponsor conduct. No claims regarding customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel appear in the provided text. Why it matters: This routine compliance exhibit functions as a statutory threshold report for beneficial ownership exceeding 5%, but the truncated disclosure prevents evaluation of Barclays PLC’s investment intent, potential board influence, or impact on CH4 Natural Solutions’ de-SPAC execution, trust value preservation, or shareholder redemption behavior.

  • What changed: Schedule 13G Joint Filing Agreement pursuant to Rule 13d-1(k). According to the signed declarations by Adage Capital Management, L.P., Robert Atchinson, and Phillip Gross, the parties are establishing joint filing procedures and allocating individual accountability for the timeliness and accuracy of their respective disclosures, while limiting cross-liability to instances where actual knowledge of inaccuracy exists. The excerpt contains no share counts, percentages, purchase prices, voting agreements, or transaction timelines. Why it matters: The filing does not alter redemption deadlines, trust distribution mechanics, extension options, merger pipelines, or sponsor conduct. It is a purely administrative securities compliance document that reports co-beneficial ownership disclosure protocols. No material business operations, customer bases, revenue streams, market valuations, technological roadmaps, strategic partnerships, active litigation, or executive personnel changes are disclosed. The only operative provision is the legal reallocation of SEC filing responsibility among the named holders.

  • What changed: A Joint Filing Agreement (Exhibit 99.1) submitted alongside a Schedule 13G beneficial ownership report, creating a procedural arrangement for five affiliated investment vehicles to satisfy their reporting obligations under Sections 13 and 16 of the Securities Exchange Act of 1934 as a single unit. The agreement stipulates that RP Investment Advisors LP, RP Select Opportunities Master Fund Ltd., RP Debt Opportunities Fund Ltd., RP Alternative Global Bond Fund, and RP Alternative Credit Opportunities Fund will file future required disclosures jointly through RP Investment Advisors LP. Richard Pilosof, Chief Executive Officer of RP Investment Advisors LP, executed the document on behalf of each fund’s general partner, and the exhibit states the arrangement stays in full force until revoked in writing by any party. Regarding SPAC-specific mechanics, the filing makes no mention of CH4 Natural Solutions’ acquisition targets, merger timelines, trust account valuations, shareholder redemption procedures, extension votes, or sponsor governance conduct. Why it matters: Investors tracking redemption deadlines, trust distributions, deal execution, or sponsor behavior will find no operative updates here. The exhibit neither advances the de-spacification clock, modifies distribution expectations, nor signals changes in capital commitment or executive oversight. It is purely an administrative disclosure mechanism confirming that multiple RP-managed pools are bundling their regulatory filings. Substantive moves affecting the redemption calendar, trust preservation strategies, or sponsor actions will require distinct filings such as going-private transaction proposals, amended registration statements, or formal board resolutions rather than routine joint filing agreements.

Show the other 10 filings
  • What changed: A Form 8-K current report announcing the mechanical separation of CH4 Natural Solutions Corporation's publicly traded units into standalone Class A ordinary shares and warrants, accompanied by Exhibit 99.1 (a corporate press release). Commencing June 22, 2026, holders of the Company’s units may elect to separately trade the underlying Class A ordinary shares (ticker: MTNE) and whole warrants (ticker: MTNE.WS) on the New York Stock Exchange. Unseparated units will continue trading under MTNE.U. The filing confirms that no fractional warrants are issued during this process, and that all listed securities carry a $0.0001 par value. Warrants are priced for exercise at $11.50 per share. Why it matters: This filing does not alter the SPAC’s SEARCHING status, trust valuation, or business combination deadline. It merely activates pre-established liquidity options by confirming the SEC declared the related registration statement effective on April 30, 2026. According to the accompanying press release, the sponsor (CH4 Natural Solutions Acquisition Sponsor LLC, an affiliate of Riverstone Earth LLC) retains its stated strategy to pursue targets with significant real-asset footprints focused on methane mitigation, supported by Riverstone Earth’s disclosed 25-year operating history in energy and infrastructure. For calendar tracking, this is a standard structural administration step rather than a catalyst for redemptions or extensions.

  • What changed: Form 4 — insider ownership report. The filing explicitly states 'No non-derivative transactions or holdings reported' for CH4 Natural Solutions Acquisition Sponsor LLC, CH4 Natural Solutions Acquisition Sponsor Holdings LLC, CH4 Natural Solutions Acquisition Sponsor Manager LLC, Riverstone Earth LLC, and LEUSCHEN DAVID M. There is no modification to the reported trust value of $10.06 per share, the 2028-05-01 deadline, or the SEARCHING status. Why it matters: As a routine compliance exhibit, the filing provides no actionable shifts to redemption windows, extension voting, or sponsor conduct. It does not contain any assertions about customers, revenue, market size, strategy, technology, or partnerships. The document solely reflects David M. Leuschen’s continued designation as Director, Chairman and CEO with 10% ownership across the listed entities, as declared by the reporting persons themselves. The absence of equity movement indicates no sponsor-funded purchases or sales that would otherwise signal capital commitment or caution ahead of the deadline.

  • What changed: Quarterly report on Form 10-Q for the period ended March 31, 2026, filed by CH4 Natural Solutions Corp (MTNE), a blank-check company still searching for a business combination target. The company completed its IPO on May 4, 2026 (after the quarter end) of 20,000,000 units at $10.00 per unit, raising $200 million. The underwriter partially exercised the over-allotment on May 8, 2026, purchasing 2,000,000 additional units for $20 million. Simultaneously, the security holdings sponsor purchased 200,000 private placement units for $2 million. Total trust proceeds of $220,000,000 were deposited. On April 22, 2026, before the IPO, the sponsor surrendered 3,833,333 founder shares for no consideration, reducing founder shares to 7,666,667. The company also amended a $300,000 promissory note with an affiliate of the sponsor to be payable on demand (June 12, 2026). Management notes substantial doubt about going concern due to insufficient working capital, but intends to rely on sponsor support. No business combination has been announced; the company remains in the search phase. Why it matters: This is the first quarterly report since the IPO, establishing the trust account size ($220 million), the per-share trust value ($10.00 per public share), and the 24-month deadline (May 2028). The sponsor's surrender of founder shares aligns insiders with public shareholders. The amended promissory note reduces financial flexibility. The going concern disclosure highlights risk if a target is not found quickly. For redemption calendar tracking, the trust is now funded and the deadline clock is running.

  • What changed: A Current Report on Form 8-K (Item 8.01 Other Events and Item 9.01 Financial Statements and Exhibits) confirming the closing of the underwriters’ partial exercise of their over-allotment option following the company’s initial public offering, accompanied by an unaudited pro forma balance sheet dated May 8, 2026. Per the filing, CH4 Natural Solutions Corporation completed its IPO on May 4, 2026, selling 20,000,000 units at $10.00 per unit for $200,000,000 in gross proceeds. Simultaneously, the company sold 200,000 private placement units to CH4 Natural Solutions Acquisition Security Holdings, LLC at $10.00 per unit for $2,000,000. On May 6 and May 8, 2026, the underwriter partially exercised its over-allotment option to purchase an additional 2,000,000 units at $10.00 per unit, generating $20,000,000. The company states that $220,000,000 in net proceeds, including $6,600,000 of deferred underwriting discounts and commissions, was deposited into a trust account with Continental Stock Transfer & Trust Company acting as trustee. The unaudited pro forma balance sheet shows 22,000,000 Class A ordinary shares subject to possible redemption valued at $10.00 per share, totaling $220,000,000. Non-trust cash holds $1,663,700, prepaid expenses total $130,955, and prepaid insurance carries $98,752. Current liabilities stand at $2,293,726 (comprising $215,781 in accounts payable, $909,610 due to related party, and $1,168,335 in accrued expenses), alongside $6,600,000 in deferred underwriting fees payable, $6,600,000 in advisory fees, and $175,000 in deferred legal fees. The accumulated deficit is reported at $(13,249,706) and total shareholders’ deficit at $(13,848,919). The report is signed by Arthuros Mangriotis, who serves as Chief Financial Officer, Chief Accounting Officer and Secretary. Why it matters: For investors monitoring redemption mechanics, this filing fixes the post-over-allotment trust floor at $220,000,000 across all 22,000,000 redeemable shares, establishing the maximum cash pool available for shareholder redemptions pending a business combination. The explicit $10.00 per-share redemption valuation provided by the company eliminates ambiguity around trust distribution ratios and confirms full over-allotment funding before entering the operational spending phase. The large advisory and deferred underwriting fee obligations ($6,600,000 each) and $(13,848,919) shareholder deficit underscore the capital deployment trajectory toward the May 1, 2028 deadline, while the absence of any merger target, extension resolution, or sponsor conduct disclosures leaves the SEARCHING mandate entirely unadvanced in this submission. No commercial metrics, customer claims, revenue projections, partnership announcements, litigation updates, or executive changes appear in the filing; all disclosed figures and structural mechanics derive solely from the company’s own prospectus-based reporting and CFO certification.

  • What changed: Routine compliance exhibit: Schedule 13G (beneficial ownership report) filed on 2026-05-11 by Sculptor Capital LP, Sculptor Capital II LP, Sculptor Capital Holding Corp, Sculptor Capital Holding II LLC, Sculptor Capital Management, Inc., and Sculptor Master Fund, Ltd. The filing identifies these affiliated entities as the reporting persons for their aggregated holdings in MTNE. The filing contains no provisions affecting the 2028-05-01 deadline, the $10.06 per-share trust value, extension voting rights, or target acquisition progress. The reporting persons do not disclose share quantities, purchase/sale dates, or percentage ownership, meaning no mechanical adjustments to redemption calculus or trust preservation have been introduced. Why it matters: Because the filing is purely an ownership disclosure, it does not trigger any redemption calendar shifts, trust distribution changes, or sponsor conduct alterations. The filing makes no claims about customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel. Investors relying on this submission see only that Sculptor Capital-affiliated funds cross or maintain a reportable threshold, but without disclosed volume or price, the document carries minimal immediate weight for deal-timing or liquidation projections.

  • What changed: Form 8-K current report disclosing the consummation of an initial public offering, a simultaneous private placement, and the partial exercise of the underwriters’ over-allotment option. Document identification: This is a Form 8-K current report filed pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 detailing post-IPO capitalization adjustments. Mechanics governing redemption thresholds, trust balance, and extension timelines: The registrant states that upon closing the initial public offering and private placement on May 4, 2026, $200,000,000, including $6,000,000 of deferred underwriting discounts and commissions, was deposited into a trust account with Continental Stock Transfer & Trust Company acting as trustee. Management reports that on May 8, 2026, the underwriter exercised its option in part and purchased 2,000,000 additional Option Units at $10.00 per unit, generating $20,000,000 in gross proceeds that increased the aggregate Trust Account balance to $220,000,000 (now reflecting $6,600,000 of deferred underwriting discounts and commissions). The registrant further discloses that CH4 Natural Solutions Acquisition Sponsor LLC surrendered 3,833,333 founder shares on April 22, 2026, leaving 7,666,667 Class B ordinary shares outstanding, with up to 1,000,000 shares subject to forfeiture if the remaining over-allotment is not exercised within 45 days. The independent registered public accounting firm, WithumSmith+Brown, PC, qualifies the financial statements with a going concern warning, noting that the company’s working capital does not support operations for at least one year without additional sponsor loans or capital contributions. Substance regarding targets, strategy, and contractual commitments: The registrant declares that it has not selected any specific business combination target and has not engaged in any substantive discussions with prospective targets as of May 4, 2026. Management discloses that total transaction costs amounted to $8,351,843, broken down into $6,000,000 in deferred underwriting fees, $250,000 in upfront underwriting fees, and $2,101,843 in other offering costs. Additionally, the registrant records a $6,000,000 charge against earnings representing a 3.00% advisory fee payable to Santander US Capital Markets LLC, which is contingent upon the completion of an initial business combination. Why it matters: Anchors the post-IPO trust baseline that dictates per-share redemption pricing and frames the 24-month business combination window opening May 4, 2026. Quantifies the expanded deferred underwriting liability and fixed advisory commitment that reduce net capital available for acquisitions, while the sponsor’s share surrender recalibrates potential post-deal dilution ahead of any extension vote. The auditor’s liquidity disclaimer signals reliance on continued sponsor financing, and the explicit lack of target discussions confirms the search phase remains open, preserving shareholder redemption rights through the statutory period.

  • What changed: Routine compliance exhibit and joint filing agreement for a Schedule 13G beneficial ownership report. The filing establishes a Rule 13d-1(k) joint filing arrangement among Linden Capital L.P., Linden GP LLC, Linden Advisors LP, and Siu Min Wong for a statement dated May 5, 2026. It grants execution authority to Saul Ahn using a legacy power of attorney dated June 10, 2019 from a prior Haymaker Acquisition Corp II filing. Regarding redemption mechanics, trust value ($10.06 per share), deadline (2028-05-01), extensions, deal progress, and sponsor conduct, this document discloses zero operational updates, amendment triggers, or shareholder action commitments. Why it matters: As a procedural cover sheet rather than a substantive disclosure, it requires investors to defer to the unattached Schedule 13G body for actual share totals, acquisition methods, and intent declarations that could signal coordinated voting blocs ahead of the merger window. The document contains no claims about customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel attributable to management or third parties. Its primary utility lies in clarifying reporting chain and cross-entity alignment among the listed holding vehicles and individuals, which may affect quorum calculations or consent solicitations during future extension votes or tender offers.

  • What changed: Form 8-K filed to report the completion of the initial public offering (IPO) of CH4 Natural Solutions Corporation, including the entry into various definitive agreements and the deposit of proceeds into the trust account. The Company completed its IPO of 20,000,000 units at $10.00 per unit, generating $200,000,000 in gross proceeds (before underwriting discounts) plus $2,000,000 from the private placement of 200,000 units to the sponsor affiliate. All net proceeds (including $6,000,000 in deferred underwriting discounts) were deposited into the trust account. The board of directors was appointed, with three independent directors. The Amended and Restated Memorandum and Articles were adopted. No business combination target was announced; the SPAC remains in search phase. Why it matters: This filing establishes the trust structure and redemption mechanics for the SPAC. The trust holds approximately $10.06 per public share (including interest). The deadline to complete a business combination is 24 months from the closing, i.e., by May 2028. The sponsor and insiders have agreed to lock-up provisions and to vote in favor of any business combination. The filing confirms that the SPAC is now funded and operational, with $200 million in trust plus sponsor capital, searching for a target in methane mitigation/real assets. No redemption rights are triggered as this is the IPO closing, not a deal vote.

  • What changed: Final prospectus (424B4) for the initial public offering of CH4 Natural Solutions Corporation, a blank-check company (SPAC) formed to acquire a business with a focus on methane mitigation and real-asset industries. The SPAC completed its IPO, raising $200 million ($230 million if over-allotment exercised) in trust at $10.00 per share. The deadline to complete a business combination is 24 months from closing (May 2028). No target has been identified. The sponsor (CH4 Natural Solutions Acquisition Sponsor LLC, controlled by David Leuschen via RSE) holds 6,666,667 founder shares (after forfeiture) and 200,000 private placement units. The sponsor paid $0.003 per founder share. The auditor's report includes a going-concern emphasis. The SPAC has a 15% redemption limit in shareholder votes and the sponsor has agreed to vote for any deal. The sponsor's previous SPACs include some that were successful, some that filed for bankruptcy, and some that resulted in litigation. Why it matters: This is a new SPAC IPO with a sponsor that has a notable but mixed track record (Riverstone-affiliated). The trust value is standard at $10.00 per share. The 24-month deadline is typical. The sponsor's low cost basis creates a strong incentive to close a deal. The going-concern opinion signals that the SPAC needs the IPO to survive. The focus on methane mitigation and real assets may appeal to certain investors. The litigation history of the sponsor (Leuschen and Tepper named in lawsuits related to prior SPAC mergers) is a risk factor. The 15% redemption limit could affect shareholder rights. Overall, the filing provides full disclosure of the SPAC's terms and risks.

  • What changed: SEC Form 4 — Statement of Changes in Beneficial Ownership (routine compliance exhibit). On 2026-05-04, the filing records that CH4 Natural Solutions Acquisition Sponsor Manager, LLC (10% owner), Riverstone Earth LLC (10% owner), and David M. Leuschen (director, Chairman and CEO, 10% owner) executed an open-market purchase of 200,000 shares. The submission notes the reporting group holds 200,000 shares following the transaction. No alterations to the SPAC’s trust account valuation, redemption window mechanics, extension voting procedures, or target search progress are documented. Why it matters: The reported open-market acquisitions by the chairman/CEO and sponsor-affiliated vehicles constitute routine equity accumulation that operates independently of the trust account and does not adjust shareholder redemption entitlements, conversion ratios, or extension triggers. The filing contains no strategic guidance, customer or revenue metrics, market size assertions, partnership disclosures, litigation references, or personnel changes beyond the transaction itself. Because insider purchases of this type do not amend governing documents or modify liquidity event timelines, the submission functions solely as a statutory ownership disclosure. Investors monitoring the May 2028 deadline, trust account sufficiency, or sponsor forfeiture conditions should expect that material developments will require subsequent registration statement amendments, proxy solicitations, or press releases rather than Form 4 reporting.

In plain English

tap a term to open it

Every piece of jargon this page could have used, and what it actually means.

Open the plain-English guide
No floor / floorlessthe cash guarantee is gone — the price is unprotected

A SPAC's downside protection is not the cash in trust; it is your right to demand that cash. Once the redemption window closes, the cash stays with the company and the share can trade anywhere.

Redemption deadlinethe last day to hand shares back for cash

Set by the filing that calls the meeting. Tender after it and the company is under no obligation to pay you the trust value.

Broker action datethe day your broker needs the instruction — earlier than the official date

Brokers batch redemption instructions to the transfer agent, so the practical cutoff is roughly two business days before the published deadline. This is the date that actually costs people the floor.

Cash in trust / trust per sharethe cash the company is holding for each public share

Filed quarterly in the 10-Q's XBRL. It earns interest between filings, so the figure on a given day is slightly higher than the last filed one — where we show that we label it an estimate.

Trust discountbuying below the cash held for you

Only meaningful while a redemption right exists. On a floorless name the same arithmetic is not a discount, it is the market pricing distress, and this product will not call it a yield.

Dilutionhow much of the company new shares take from you

Sponsor promote, PIPE shares, warrants and rights all issue stock that did not pay $10 for it. The headline deal value is before that; the effective value is after.

Pro-forma equitywhat the company is valued at once the deal closes

The combined company's equity value assuming the announced terms and the redemptions that have actually happened.

ARShow much upside you get per unit of downside

SpacBrain's asymmetric-return score. It is deterministic — the same inputs always produce the same number — and it is capped, not zeroed, when the floor is gone.

De-SPACthe day the SPAC becomes the real company

The shares stop being a claim on a pot of cash and start being equity in an operating business. Roughly 80% of recent de-SPACs traded below $10 within a year.

Outside datethe contractual long-stop for closing the deal

A deadline between the SPAC and its target, not between the SPAC and you. It confers no right to cash, which is exactly why it must never be counted as a redemption window.
