Plum IV

Lowering the transaction valuation to $3,150,000,000 and trimming 30,000,000 earnout shares fundamentally alters the economic upside and dilution profile for public shareholders versus target owners. Moving the closing window to April 30, 2027 pushes completion past the stated January 16, 2027 business combination deadline, meaning the SPAC must secure a formal extension and preserve the recorded $10.69 trust per share before that date to avoid liquidation. Raising non-redemption shares to 3,000,000 demonstrates active sponsor management of expected redemptions to protect trust capital. Executively, Chief Executive Officer Kanishka Roy and Controlled Thermal Resources President James Turner signed the amendment, which also contains forward-looking assertions about the combined entity’s plan to domesticate in Delaware and advance the Hell’s Kitchen Project, alongside explicitly flagged risks regarding lithium and critical mineral price volatility, development cost overruns, and regulatory environmental compliance. All transactional adjustments and strategic projections are sourced directly to the filed Second BCA Amendment, the accompanying 8-K narrative, and the executive signatories named therein.

This filing recalibrates the capital preservation and exit framework for PLMK by replacing an imminent liquidation trigger with a conditional extension pathway, while locking in a precise, trust-backed redemption floor of approximately $10.6973 against a near-term market valuation of $10.77. The authorization of post-extension board-level term adjustments upon sponsor request centralizes timeline control with Plum Partners IV, LLC and materially alters the governance profile for minority public shareholders. Explicit liquidity warnings indicate that secondary market transactions at premiums to the trust-derived redemption price may prove impossible, forcing holders to either accept the cash distribution, tender before the July 10, 2026 cutoff, or maintain exposure under the revised charter. These provisions directly govern trust drawdown sequencing, capital deployment windows, and the timing/risk parameters for redemption decisions across all registered share classes.

The disclosure forces an immediate redemption decision tomorrow against a hard trust floor that trades slightly below the referenced $10.77 secondary market price, while management explicitly warns that insufficient liquidity could trap holders who avoid redemption but seek an exit. The structural arrangement cedes post-January 2027 timing authority to the sponsor Plum Partners IV, LLC and the board via unilateral resolution, effectively preserving capital for twelve additional months while suspending further shareholder votes and market pricing discovery. For investors tracking trust depletion, extension pacing, and sponsor leverage, this filing confirms a prolonged hold period, centralized renewal discretion, and the continued absence of an announced merger target, financial metrics, or acquisition due diligence updates.

This filing establishes the binding redemption calendar and triggers a trust preservation strategy designed to limit outflows ahead of the extension vote. The documented non-redemption incentive ratio and per-investor caps signal the Sponsor’s active effort to maintain liquidity in the trust account while aligning external holder economics with continued operations. The Company attributes forward-looking projections regarding the number of executed agreements and actual transfer timing to its management, noting that 'NO ASSURANCES ARE MADE THAT A NON-REDEMPTION INCENTIVE OF ANY KIND WILL BE OFFERED AND THE ACTUAL TERMS... MAY DIFFER MATERIALLY.' The exhibit incorporates a 'Most Favored Nation' clause, granting participating investors the contractual right to adopt materially more favorable consideration terms if extended to other counterparties, which directly impacts negotiation leverage and trust dilution calculus. Pursuant to the Company’s stated policy, it will not utilize trust account funds to pay potential excise taxes under the Inflation Reduction Act of 2022 upon redemption, protecting remaining balances. The filing cross-references a Registration Rights Agreement and a Letter Agreement, both dated January 14, 2025, indicating ongoing structural and regulatory commitments. Reported by Chief Executive Officer Kanishka Roy on June 30, 2026.

This disclosure structurally redefines the immediate incentives surrounding the extension vote by replacing potential cash payments to non-redeeming shareholders with deferred, equity-based compensation tied directly to deal consummation. The Company's stated strategy aims to preserve trust capital by offering Founder Shares as a non-cash alternative to redemptions, while the explicit 9.9% participation cap and 1-to-7 payout ratio limit dilution. The mandatory Rule 10b-5 waiver compels participating investors to legally shield management from insider trading allegations during the solicitation window, altering standard disclosure norms for the campaign. The strict July 8 redemption cutoff forces public shareholders to make a binary choice between immediate liquidity and a delayed, transaction-contingent equity payout, fundamentally changing the redemption yield calculation ahead of the July 10 vote.

This administrative shift directly recalibrates the liquidity and voting timeline for public shareholders. The revised redemption window closes on July 8, 2026, granting investors eight additional days to elect cash-out rights before the extension vote. The postponement indicates management intends to continue shareholder outreach rather than convening immediately, which preserves the trust environment while keeping acquisition pursuits active. Procedural requirements outlined in the filing—such as the mandate to secure a control number from the transfer agent at 917-262-2373 or proxy@continentalstock.com up to 72 hours in advance—also establish the exact compliance path for broker-mediated and direct registrants to participate in the solicitation.

The administrative shift materially alters the redemption calendar by granting shareholders an additional eight days to elect to redeem their shares before voting on the extension amendment proposal. The proposed amendment would extend the initial business combination deadline to January 16, 2027, or to July 16, 2027 if all 6 additional monthly extensions are exercised. Preserving this window prevents forced liquidity traps and allows investors more time to evaluate the extension terms relative to the company's target search progress. Separately, the attached press release attributes its investment thesis to the sponsor's leadership, stating the team possesses a 'track record of sourcing and executing complex public-market transactions' and that Plum IV 'aims to identify companies positioned to deliver long-term value through technological advancements, disruptive business models, and secular long-term trends.' No deal target, purchase price, historical operating results, or active litigation details are disclosed in this submission.

This vote determines whether the SPAC will continue to pursue the CTR deal or liquidate. If the extension is not approved and no business combination closes by July 16, 2026, Plum will liquidate, redeeming public shares at approximately $10.67 per share (as of June 12, 2026) and warrants will expire worthless. The trust account holds about $184,121,199. The sponsor (Plum Partners IV, LLC) owns 27.9% of shares and will vote for the extension; they have invested $4,425,000 and would lose their entire investment in liquidation. Shareholders may redeem their shares in connection with the extension at a per-share price based on trust value. The filing provides redemption deadlines (June 30, 2026), voting requirements (two-thirds majority for extension), and details on sponsor conflicts of interest.

The proxy materially restructures the trust preservation timeline by deferring the liquidation trigger by roughly 18 months while shifting post-January 16, 2027 extension authority from shareholder votes to unilateral board resolutions activated solely by Sponsor requests. The mandatory pre-meeting tender deadline and 15% redemption ceiling directly constrain cash exit pathways and amplify liquidity risk for public holders, particularly because the Registration Statement is already effective yet closure is deliberately postponed. Sponsor economics remain insulated through waived liquidation distributions and concentrated voting control, effectively pressuring public shareholders to either cash out at the recorded trust balance or sustain a thinly traded entity awaiting regulatory and operational finalization with CTR.

Compressing these internal covenants tightens the operational path toward the SPAC’s fixed business combination deadline, which directly dictates the sequencing of the upcoming S-4/Proxy Statement/Prospectus filing, record date establishment, and shareholder vote calendar where redemption windows open. The 50/50 antitrust fee split increases purchaser transaction costs, while the mutual-consent restriction on HSR extensions removes unilateral delaying power for either side. Per the filing’s forward-looking statements section, Plum IV and the Company attribute to themselves expectations regarding the combined entity’s future financial performance, expected trading on Nasdaq, and the building of the Company’s flagship Hell’s Kitchen Project. Management also identifies industry-specific exposures, including fluctuations in demand and prices for lithium and other critical minerals, potential capital expenditure delays or cost overruns, and compliance, environmental, and safety obligations. The Class A ordinary shares’ associated whole warrants remain exercisable at an exercise price of $11.50. Plum IV plans to transfer by way of continuation from the Cayman Islands to Delaware and domesticate as a Delaware corporation prior to Closing.

Postponing financial and antitrust deliverables delays the compilation and SEC filing of the Form S-4 Registration Statement and Proxy Statement/Prospectus, which indirectly pushes back the schedule for shareholder voting and potential redemption windows. The filing makes no alteration to the SPAC’s contractual business combination termination date, maintains existing trust account distribution protocols, and does not introduce new sponsorship governance or penalty clauses. Management’s forward-looking statements, as explicitly attributed in the filing’s risk section, project anticipated closing benefits, Nasdaq trading expectations, and strategic development of the flagship Hell’s Kitchen Project. The parties’ enumerated risk factors specifically highlight exposure to lithium and other critical mineral price volatility, exploration and development cost overruns, raw material securing challenges, environmental and safety compliance obligations, and geopolitical disruptions. Executive signatories confirm Kanishka Roy as Chief Executive Officer and President of the purchasing entities, and James Turner as President of the target. Cover page data notes whole warrants carry an $11.50 exercise price. The stated $10.69 per share trust value and January 16, 2027 deadline from the initial case parameters remain unmodified by this amendment.

The filing confirms the announced deal with CTR, updates trust value (key for redemption calculations), and highlights liquidity and going concern risks. The deadline is approaching, making timely shareholder vote and deal closing critical.

The filing confirms the CTR deal is announced, but only 60% of CTR stockholders are locked in via a transaction support agreement; there is no PIPE or minimum cash condition disclosed yet. The trust balance is ~$181.3 million, well above the initial $10.10 per share. However, the company has a working capital deficit of $70,710, cash of only $296,249, and the auditor flags substantial doubt about going concern if the merger fails by the July 14, 2026 deadline. The sponsor note can convert into equity at $10.00 per share, which is dilutive and below trust value. Note 5 reports a delayed Section 16 filing for a 25,000-share director transfer on April 25, 2025.

This filing is the definitive agreement for the SPAC's business combination, providing investors with the full terms of the merger, consideration structure, earnout, financing commitments, redemption incentives, and conditions to closing. The target is a lithium developer (Hell's Kitchen Project) in a critical minerals sector. The trust value is $10.69 per share, and the deadline is January 16, 2027, but the outside date for the deal is December 31, 2026. The minimum cash condition of $100 million and sponsor-backed PIPE provide a floor on trust proceeds. The earnout structure and lock-up release thresholds create alignment with stock price performance.

This filing confirms that Plum IV has found and signed its merger partner, Controlled Thermal Resources, moving from a blank-check shell into a definitive business combination. For the first time, investors see the valuation framework: a $4.5 billion enterprise value (implied by Aggregate Merger Consideration, computed from Public Company (Pre-Capital Raise) Valuation of $4.5B divided by Per Share Price), earnout triggers, the trust size ($179.2M minimum), the minimum cash to close ($100M), and the source of additional financing. The document also discloses that CTR's business is lithium and geothermal at the Hell's Kitchen Project. The trust per-share value of $10.69 is above the $10.00 baseline, but the redemption deadline and the negotiated $100M minimum cash condition mean any excess redemptions above the implied trust outflow could kill the deal. The outside date of December 31, 2026, and the Material Consents deadline of May 7, 2026, are key calendar items. The Sponsor's commitment to fund at least $15M in PIPE and the requirement for a $10M bridge note provide some floor on available cash. The earnout structure connects seller consideration to post-close stock performance.

The documented assumptions directly anchor redemption calculus and post-closing liquidity: a zero-redemption model dictates the baseline trust-derived capital (~$180 million plus accrued interest) feeding the combined entity’s initial construction funding, thereby defining the dilution profile and execution runway before the January 16, 2027 deadline expires. Beyond mechanics, the press release and presentation advance numerous operational, strategic, and financial claims attributed to specific parties and external sources. CEO Rod Colwell and CEO Kanishka Roy frame the Hell’s Kitchen Project as delivering up to 650 megawatts of clean baseload power and 100,000 metric tons per year of lithium carbonate to service hyperscale data center and AI infrastructure growth, citing U.S. Department of Energy directives, IEA, Goldman Sachs, and EIA data forecasting 134 gigawatts of new U.S. baseload demand by 2030 and data centers consuming roughly 8% of national power by that date. Management attributes accelerating lithium consumption to battery energy storage systems (BESS), referencing projections of 700,000-plus tonnes of lithium carbonate equivalent by 2035 from BMI, Rho Motion, Canaccord Genuity, and a 2025 DoD Battery Briefing. Financial forecasts in the presentation, attributed to a Definitive Feasibility Study prepared by Baker Hughes under SEC S-K 1300 guidelines, outline Stage 1 annual revenue trajectories ranging from $3.481 billion to $4.307 billion based on variable product pricing, with estimated operating margins of approximately 72% for power generation and 58% for lithium production. Permitting milestones are credited to Imperial County Planning and Development Services (Conditional Use Permit secured January 2024), federal FAST-41 interagency coordination, and California Regional Water Quality Control Board approvals. Technology and commercial partnerships cited include Baker Hughes for field development planning, Aquatech for direct lithium extraction processes, Imperial Valley College for local workforce training, and unspecified strategic investments from global automotive manufacturers. Advisory teams are identified as Hall Chadwick and Cohen & Company Capital Markets for financial execution, Greenberg Traurig LLP for Plum IV legal counsel, and Duane Morris LLP for CTR legal counsel. All projections, capacity targets, peer valuation benchmarks, and risk disclosures remain expressly conditional upon shareholder ratification, SEC registration statement effectiveness, HSR waiting period expiration, and customary closing criteria.

According to the attached press release and investor presentation, CTR advances the Hell’s Kitchen Project in California’s Salton Sea basin. Management projects up to 650 MW of renewable baseload power and 100,000 metric tons per year of lithium carbonate at full buildout, alongside 3,000,000 metric tons per year of potash and 450,000 metric tons per year of polymetallics (zinc/manganese). Stage 1 targets 50 MW of power and 25,000 metric tons per year of lithium. CTR attributes $285 million in private capital deployed to date, a January 2024 conditional use permit, and federal FAST-41 project designation. Technology claims originate from a demonstration optimization facility that operated Direct Lithium Extraction for 770 hours at 1/15th commercial scale, achieving greater than 97% lithium recovery. A Baker Hughes Definitive Feasibility Study prepared under SEC S-K 1300 guidelines supports a 30-year operating life for Stage 1. Market narratives cite data centers consuming more than 134 GW of new U.S. baseload power by 2030 and global lithium demand doubling by 2035, sourced to IEA, Goldman Sachs, and Department of Defense briefings. The transaction implies a $4.5 billion pre-money equity value and ~$4.7 billion pro forma enterprise value, structured around a $4.5 billion CTR rollover, a $125 million convertible note and PIPE priced at $10.00 per share, and the ~$180 million trust balance. Forward-looking financial models estimate up to $4.3 billion in annual revenue at capacity, with management attributing Stage 1 margin expectations of roughly 72% for power and 58% for lithium. Explicit risks flagged by both parties include failure to obtain shareholder approval, inability to complete by the SPAC deadline, permitting reversals, construction delays, cost overruns, and commodity price volatility.

The presentation attributes multiple operational and market claims exclusively to ACR, noting Plum IV makes no representation regarding their accuracy. ACR President Jim Turner and Strategic Advisor David Andrada describe a Direct Lithium Extraction process operating at 1/15 th commercial scale for 770 hours, achieving greater than 97 % lithium recovery and producing lithium chloride converted to lithium hydroxide monohydrate. Stage 1 capacity is claimed at 50 MW power, ~100,000 tpa lithium, ~450,000+ tpa polymetallics, and ~3,000,000+ tpa potash. ACR states $285M was invested over 12 Years across two existing ~25 MW e wells at the Hell’s Kitchen project in Imperial County, California, with a Conditional Use Permit obtained in January 2024. Market context cites data centers using more than 134 GW of new baseload power by 2030, global lithium demand doubling by 2035, BESS requiring over 700,000 tonnes LCE by 2035, and the U.S. importing ~93% of potash needs. Leadership biographies list Rod Colwell as CEO & Board Director, Jim Turner as President & Board Director, Eric Thayer as CFO, Danny Suubam as Manager of Geology, Paul Mead as Senior Environmental Permitting Manager, Gerald Font as General Project Manager, and Lauren Rose as Chief Communications Officer. Because all metrics are supplied solely by ACR under explicit forward-looking disclaimers, they reflect management’s developmental projections rather than audited corporate performance or binding contractual commitments.

For redemption and trust monitoring, the lack of a definitive agreement preserves the current liquidation deadline and keeps the trust intact, with no proxy solicitation or redemption window initiated. However, the disclosed financing roadmap signals substantial pre-closing capital formation that will structurally define post-combination equity dilution and liquidity cushions. Because the prospectus explicitly disclaims independent verification, attributing all capacity, technological, and market-size assertions solely to ACR and its advisors, investors must treat the stated metrics and partnership references as unreinforced projections until the S-4 registration statement subjects them to SEC review and auditor scrutiny. Tracking the transition from soft-sounding to hard PIPE commitments will be the next critical indicator of deal viability before shareholders face a formal redemption election.

This announcement shifts investor focus toward fundamental validation while preserving standard SPAC exit mechanics. All subsequent financial terms, redemption procedures, lock-up arrangements, and projected holdco capitalization will be disclosed in a future Form S-4 and preliminary proxy statement once a definitive agreement is executed. Until then, shareholders may redeem shares for their pro rata trust value without penalty. The press release also discloses key transaction participants: Hall Chadwick is serving as exclusive financial and lead capital markets advisor to ACR; Cohen & Company Capital Markets serves the same role for Plum IV; Greenberg Traurig, LLP advises Plum IV; and Duane Morris LLP advises ACR. Subject to these structural safeguards, the filing contains substantive operational claims attributed entirely to ACR and unverified by the SPAC: ACR expects its Hell’s Kitchen development at the Salton Sea in California to deliver approximately 50 megawatts of renewable baseload electricity and an estimated annual production of up to 100,000 metric tons of lithium carbonate over four project stages. The company states it has secured over US$ 285 million in private investment to date and completed a Definitive Feasibility Study validated by Baker Hughes. Additionally, ACR notes that research and development is targeting additional critical minerals identified by the Idaho National Laboratory, including potash, zinc, manganese, rubidium, cesium, and rare earth materials. CTR CEO Rod Colwell asserts the project will “supercharge domestic supply chains,” while Plum IV CEO Kanishka Roy characterizes the combination as a “significant opportunity to support a strategic U.S. initiative.” Both leadership teams caution that the letter of intent is non-binding, definitive terms may differ materially, and consummation requires board approvals, shareholder votes, regulatory clearances, and customary closing conditions.

This filing moves the SPAC into active target evaluation, anchoring redemption-era decision-making well ahead of the January 16, 2027 deadline. Per the press release, which explicitly states that all information concerning American Critical Resources was provided solely by ACR and not independently verified by Plum IV, ACR claims its Hell’s Kitchen project in Imperial County, California, is designed to deliver approximately 50 megawatts of renewable baseload electricity and an estimated annual production of up to 100,000 metric tons of lithium carbonate across four project stages. ACR further claims the venture has secured over US$ 285 million in private investment to date, completed a Definitive Feasibility Study validated by Baker Hughes, and is conducting research and development to unlock potash, zinc, manganese, rubidium, cesium, and rare earth materials identified by the Idaho National Laboratory. Rod Colwell, CEO of CTR, asserts the resource will supercharge domestic supply chains and expand U.S. leadership in low-carbon minerals exports. Kanishka Roy, CEO of Plum IV, states the alliance advances U.S. supply chain resilience and represents a significant opportunity to support strategic national initiatives while creating long-term shareholder value. Because Plum IV formally disclaims verification obligations until a definitive agreement is executed, public shareholders must evaluate the stated megawatt output, lithium tonnage, private funding total, and mineral recovery roadmap as unsubstantiated projections when calculating redemption thresholds and expected post-merger enterprise value.

The trust per-share value ($10.29) has increased from the initial $10.10 due to interest, but the SPAC faces a tight deadline and a going concern warning. The new sponsor loan provides short-term liquidity but signals the sponsor's willingness to support the process. No target has been announced, making the extension deadline the next critical event for public shareholders.

This financing mechanism provides targeted liquidity up to $1,500,000 conditional on deal closure, removing immediate repayment pressure or interest costs while legally insulating the trust account from sponsor recourse. The $10.00 conversion pricing establishes a defined equity valuation floor for sponsor contributions upon merger. Because the instrument auto-forgives without a completed transaction, it aligns sponsor incentives toward deal execution without introducing monthly debt servicing obligations or threatening the shareholder redemption pool ahead of the January 16, 2027 deadline.

Establishes baseline financial condition post-IPO. Trust value per share slightly above $10.10 may affect future redemption math. The going concern warning signals time pressure, which may influence sponsor behavior or deal timeline. No extension yet disclosed. The filing provides the first cash burn rate and expense visibility for investors tracking deal progress.

What changed: A routine SEC compliance exhibit (Schedule 13G/A amendment) reporting beneficial ownership of PLMK equity by Meteora Capital, LLC. The provided excerpt discloses no numerical changes in share count, percentage ownership, acquisition cost, or purpose of acquisition attributable to Meteora Capital, LLC. Consequently, the filing records no explicit updates regarding redemption deadlines, trust value distributions, extension timelines, deal execution progress, or sponsor conduct. The text also contains zero attributed statements concerning customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel. Why it matters: Schedule 13G/A amendments track institutional position adjustments that can influence voting dynamics, liquidity conditions, and post-merger governance as a SPAC navigates structural milestones. Monitoring how holders like Meteora Capital, LLC adjust stakes relative to the 10% beneficial ownership threshold helps investors anticipate whether large shareholders are preparing for, supporting, or exiting ahead of redemption windows, extension votes, or merger completions. Without the full amendment data, the specific capital allocation timing, shareholder alignment, or impact on deal progression remains indeterminate.(flagged for human review)

What changed: Quarterly report (Form 10-Q) for Plum Acquisition Corp. IV for the period ended June 30, 2026, filed to disclose the financial condition of this SPAC, which has announced a business combination. The SPAC held an extraordinary general meeting on July 10, 2026, where shareholders approved an extension of the business combination deadline from July 16, 2026 to January 16, 2027, with the ability to extend further monthly until July 16, 2027. In connection with that vote, holders of 13,540,384 public shares redeemed at approximately $10.71 per share, for an aggregate redemption of ~$145 million, leaving ~$39.7 million in the trust account. Also on July 9, 2026, the sponsor and independent directors voluntarily converted 5,749,999 Class B shares into Class A shares, leaving one Class B share outstanding after redemptions. The trust value dropped from $184.4M to ~$39.7M as a result. The business combination agreement with CTR was amended on July 6, 2026, reducing the valuation used to calculate merger consideration from $4.5B to $3.15B, reducing earnout shares from 100M to 70M, extending the closing deadline to April 30, 2027, increasing the maximum shares issuable for non-redeeming shareholders from 2M to 3M, and extending the antitrust filing deadline to September 30, 2026. Working capital was negative $1.4M at June 30, 2026, and the company acknowledged substantial doubt about its ability to continue as a going concern. Why it matters: The massive shareholder redemptions (~78% of public shares) dramatically reduced the trust available to fund the business combination, putting the deal at significant risk. The company is relying on a PIPE financing to meet the minimum cash condition, which is not yet assured. The amendment reducing target valuation by ~30% signals either a renegotiated deal or that the target's value changed substantially. The sponsor voluntarily converting nearly all Class B shares (just before the redemption deadline) suggests alignment efforts with public shareholders, but those converted shares can't access trust proceeds. The negative working capital and going concern warning are red flags for investors.

What changed: Schedule 13G/A (Amended Beneficial Ownership Report). The supplied excerpt provides no amendment data, share quantities, percentage stakes, or effective dates. It exclusively lists three related entities as co-filers: AQR Capital Management, LLC; AQR Capital Management Holdings, LLC; and AQR Arbitrage, LLC. An amended 13G typically discloses a change in ownership crossing the 5% threshold, a shift between sole and shared voting or investment power, or a correction to prior disclosures, but none of those operational specifics appear in the text provided. Why it matters: In a SPAC environment with a declared deal, a $10.69 per-share trust, and a 2027-01-16 deadline, institutional ownership filings monitor how arbitrage desks and asset managers position capital ahead of shareholder redemptions, merger approvals, or sponsor extensions. The presence of AQR Arbitrage, LLC alongside management arms suggests potential merger-arbitrage or market-neutral positioning rather than long-horizon equity conviction, which directly impacts floating share liquidity and redemption pressure dynamics. Because the excerpt contains zero numerical metrics, amendment reasons, or transaction dates tied to Plum IV, investors cannot yet determine whether the filing reflects accumulation, distribution, administrative restructuring, or a mere periodic update relative to the redemption or extension timeline.

What changed: SEC Schedule 13G (beneficial ownership report). Context Capital Management, LLC, Michael S. Rosen, William D. Fertig, Charles E. Carnegie, and Context Partners Master Fund, L.P. filed jointly to report aggregate beneficial ownership exceeding five percent of PLMK common stock. The excerpt lists only the reporting persons; it does not disclose the exact percentage, share quantity, acquisition price, or date of purchase. Why it matters: The filing repositions the recorded shareholder registry ahead of the 2027-01-16 redemption deadline. For investors monitoring redemption mechanics, trust preservation, and merger approval pathways, a newly identified multi-entity voting block clarifies which parties hold concentrated leverage over the shareholder vote. The filing indicates these holders maintained or increased their PLMK positions post-announcement rather than exercising redemptions, which mechanically reduces the residual share count available for cash-out and may support the sponsor’s fulfillment of minimum net tangible asset or financing conditions required to close the business combination. The document contains no information on customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel.

What changed: A Schedule 13G Joint Filing Agreement (Exhibit A) authorizing Linden Capital L.P., Linden GP LLC, Linden Advisors LP, and Siu Min Wong to submit a single beneficial ownership statement for Plum Acquisition Corp. IV shares on July 16, 2026, pursuant to Rule 13d-1(k), executed solely by Saul Ahn in multiple representative capacities. This filing addresses zero variables in the redemption deadline (stated as 2027-01-16), trust value per share ($10.69), extension procedures, deal progression, or sponsor governance. It is a routine procedural bundle that consolidates existing reporting obligations for the named affiliates under Exchange Act Section 13(d) and Securities Exchange Act of 1934 provisions. The document introduces no new equity percentages, voting directives, tender schedules, or cash distribution mechanics. Attribution for all statements rests entirely with the listed holders and their authorized signatory, Saul Ahn, who cites only a June 10, 2019 Power of Attorney and references an unrelated June 19, 2019 filing for Haymaker Acquisition Corp II. Why it matters: Because the exhibit contains no forward-looking assertions, commercial data, or mechanical triggers, it offers no new intelligence for tracking shareholder redemptions, trust account utilization, or merger negotiation milestones. Investors monitoring sponsor behavior or target company fundamentals will find no disclosures regarding customers, revenue projections, market positioning, proprietary technology, strategic partnerships, active litigation, or executive appointments. Its sole utility is confirming that the Linden affiliates and Siu Min Wong remain bundled compliants for regulatory reporting purposes on the PLMK security, requiring no adjustment to position sizing or timeline tracking based on new filings.

What changed: A Form 8-K current report filed by Plum Acquisition Corp. IV that discloses shareholder approval of charter amendments to extend the business combination deadline, alongside announcements of extensive public share redemptions and voluntary founder share conversions. According to the registrant's filing, shareholders voted to amend the company's Articles to extend the Termination Date from July 16, 2026, to January 16, 2027. The same vote authorized the board of directors to subsequently extend the deadline monthly up to six additional times without a shareholder vote, provided Plum Partners IV, LLC requests it in writing and gives five days' notice, establishing a firm final expiration of July 16, 2027. In connection with the meeting, the registrant states that holders of 13,540,384 Public Shares exercised their redemption right at a price of approximately $10.71 per share, withdrawing an aggregate of approximately $145 million from the trust account and leaving approximately $39.7 million in the trust. Additionally, Plum IV reports that on July 9, 2026, the Sponsor and independent directors voluntarily converted 5,749,999 Class B Ordinary Shares into Class A Ordinary Shares. Following these actions, the company has 10,702,490 Class A Ordinary Shares outstanding and a single Class B Ordinary Share held by the Sponsor. Why it matters: The disclosed redemptions drastically deplete the SPAC's cash reserves to $39.7 million, severely limiting the financial resources available to close a business combination. Transferring extension authority from public shareholders to the board and Sponsor shifts control over the SPAC's lifespan, potentially accelerating or prolonging deal timelines without further holder input or dilution from redemption votes. The voluntary conversion of founder shares fundamentally realigns the capitalization table by stripping away nearly all restricted equity, leaving only one non-public share. This concentration of class structure alongside the reduced trust balance alters the risk-reward profile for remaining public investors and defines the baseline equity distribution for any prospective merger negotiation.

What changed: SEC Form 4 — insider ownership report filed by Plum Acquisition Corp, IV on 2026-07-13. Director Aghamiri Aidin reported a conversion transaction on 2026-07-09 that resulted in the acquisition of 25,000 shares, leaving the reporting person with a total post-transaction holding of 25,000 shares. Why it matters: The filing exclusively tracks a single director’s post-conversion equity position and contains no provisions affecting the $10.69 trust per share, the 2027-01-16 redemption deadline, business combination progress, extension voting, or sponsor conduct. As stated in the Form 4 by Mr. Aghamiri and Plum Acquisition Corp, IV, this routine ownership disclosure does not modify the SPAC’s capitalization timeline, redemption mechanics, or announced deal status.

What changed: Form 4 — insider ownership report for Plum Acquisition Corp IV, filed to publicly log a securities position change by a corporate affiliate. Per the filing text, PLUM PARTNERS IV, LLC (described in the document as a 10% owner) executed a conversion on 2026-07-09, acquiring 5,649,999 shares and holding 6,659,999 shares afterward. Regarding SPAC mechanics, the document discloses no adjustments to the redemption threshold, the trust-per-share balance, the business combination deadline, any proposed extension schedules, or active merger agreement milestones. Concerning sponsor conduct, the record shows a routine post-announcement equity conversion without associated resignations, board rotations, or voting-control alterations. Why it matters: For investors tracking deal progress and redemption exposure, this conversion signals standard founder-class positioning rather than a catalyst for trust redepositions or deadline extensions. The filing contains no asserted claims about target customers, projected revenue, addressable market size, proprietary technology, commercial partnerships, pending litigation, or executive personnel movements. According to the reported text, the transaction exclusively documents the sponsor’s internal share accumulation at the stated counts, confirming concentrated equity alignment while introducing no new contractual terms, operational disclosures, or timeline modifiers that would materially shift investment thesis execution or cash-out mechanics.

What changed: This document is a Form 4 insider ownership report filed on 2026-07-13 (SEC accession number 0001213900-26-077740) submitted by Roy Kanishka, identified as director, Chief Executive Officer, and 10% owner of Plum Acquisition Corp., IV. The filing discloses that as of 2026-07-09, Roy Kanishka converted and acquired 5,649,999 shares, resulting in a total post-transaction holding of 6,659,999 shares. Regarding the specified tracking mechanics, the report contains no amendments, board resolutions, or shareholder notices that modify the redemption deadline of 2027-01-16, adjust the trust valuation at $10.69, trigger or reject an extension, alter the announced deal progress, or reflect sponsor conduct beyond this standard insider equity conversion. Why it matters: Because the document attributes only the reported share conversion to Roy Kanishka, it does not introduce new revenue forecasts, customer concentration claims, market size estimates, technology roadmap disclosures, partnership terms, litigation filings, or executive departures that would otherwise shift investment risk. The acquisition of 5,649,999 shares concentrates voting and economic exposure in management without altering the trust account’s $10.69 per-share baseline or the 2027-01-16 liquidation horizon, meaning redemption mechanics, capital allocation timelines, and sponsor behavior remain unchanged for portfolio tracking purposes.

What changed: A Rule 425 written communication (Form 8-K) disclosing a Second Amendment to the Business Combination Agreement for a proposed merger between Plum Acquisition Corp. IV and Controlled Thermal Resources Holdings Inc. The executing parties modified the merger contract to reduce the aggregate potential earnout shares from 100,000,000 to 70,000,000, dividing them into eight proportional tranches lowered from 12,500,000 to 8,750,000 shares each. Tranche vesting requires the Domesticated Purchaser Common Stock VWAP to meet or exceed $12.50, $15.00, $17.50, $20.00, $22.50, $25.00, $27.50, or $30.00 per share across any 20 trading days within 30 consecutive trading days. Antitrust filing obligations were pushed from July 31, 2026 to September 30, 2026. Maximum shares issuable as non-redemption incentives or sponsor reimbursement rose from 2,000,000 to 3,000,000. The mandatory closing date shifted from December 31, 2026 to April 30, 2027. The valuation benchmark for calculating merger consideration was cut from $4,500,000,000 to $3,150,000,000. Delivery deadlines for material consents were reassigned per Schedule 8.01(m). Registered warrant terms remain set at an $11.50 exercise price for one Class A ordinary share, per the securities table. Why it matters: Lowering the transaction valuation to $3,150,000,000 and trimming 30,000,000 earnout shares fundamentally alters the economic upside and dilution profile for public shareholders versus target owners. Moving the closing window to April 30, 2027 pushes completion past the stated January 16, 2027 business combination deadline, meaning the SPAC must secure a formal extension and preserve the recorded $10.69 trust per share before that date to avoid liquidation. Raising non-redemption shares to 3,000,000 demonstrates active sponsor management of expected redemptions to protect trust capital. Executively, Chief Executive Officer Kanishka Roy and Controlled Thermal Resources President James Turner signed the amendment, which also contains forward-looking assertions about the combined entity’s plan to domesticate in Delaware and advance the Hell’s Kitchen Project, alongside explicitly flagged risks regarding lithium and critical mineral price volatility, development cost overruns, and regulatory environmental compliance. All transactional adjustments and strategic projections are sourced directly to the filed Second BCA Amendment, the accompanying 8-K narrative, and the executive signatories named therein.
