Plum Acquisition Corp Iv SEC Filings

Plum Acquisition Corp. IV entered Amendment No. 1 to its Business Combination Agreement with Controlled Thermal Resources Holdings Inc. and Plum IV Merger Sub Inc. The amendment mainly pushes back several closing-related deadlines for their planned merger.

The Company now has until June 15, 2026 to deliver required financial statements and until June 30, 2026 to provide pro forma financial information for inclusion in the proxy statement/prospectus. The deadline for required antitrust filings was moved to July 31, 2026, and dates for delivering certain material consents were also extended. The filing reiterates that a Form S-4 registration statement and combined proxy statement/prospectus will be submitted to the SEC for shareholder approval of the transaction.

Plum Acquisition Corp. IV reported net income of $1.2 million for the quarter ended March 31, 2026, driven almost entirely by $1.45 million of interest on investments held in its Trust Account, while general and administrative expenses were $252,715. The SPAC held $182.7 million in U.S. Treasury securities in the Trust Account and only $93,512 of cash for working capital, resulting in a working capital deficit of $318,003. Management disclosed substantial doubt about the company’s ability to continue as a going concern because it must complete a business combination by July 16, 2026 or liquidate. During the quarter the company signed a Business Combination Agreement to merge with Controlled Thermal Resources Holdings Inc., with Plum redomiciling from the Cayman Islands to Delaware before closing and all Class B founder shares converting into common stock at the merger’s effective time.

Plum Acquisition Corp reports a passive ownership disclosure of 1,151,242 shares of Class A Common Stock, equal to 6.22% of the class. The filing identifies Meteora Capital, LLC and Vik Mittal as the reporting persons with shared voting and dispositive power over these shares.

Plum Acquisition Corp. IV Schedule 13G/A: three affiliated reporting persons jointly disclose beneficial ownership positions in the issuer. Westchester Capital Management, LLC reports 921,100 shares (representing 4.98%), while Virtus Investment Advisers, LLC and The Merger Fund each report 873,367 shares (each 4.72%), based on 18,492,875 shares outstanding as of March 31, 2026.

The filing breaks out voting and dispositive powers: Westchester holds 47,733 shares of sole voting/dispositive power and shares power over 873,367 shares; Virtus and The Merger Fund report only shared voting and dispositive power over 873,367 shares. The statement is signed by compliance officers and counsel.

Plum Acquisition Corp. IV is a Cayman Islands-based blank check company formed to complete a business combination, with no operating revenues to date. It raised $172,500,000 from an initial public offering of 17,250,000 units on January 16, 2025, plus $6,728,750 from a concurrent private placement, and placed $174,225,000 in a trust account.

The company has signed a Business Combination Agreement with Controlled Thermal Resources Holdings Inc. (CTR), under which a merger sub will combine with CTR and Plum will domesticate from Cayman to Delaware. All Class A and Class B ordinary shares and warrants will convert into corresponding Delaware securities on a one-for-one basis, and Class B will convert into common stock at the merger effective time.

Public shareholders are entitled to redeem their shares at a price initially anticipated to be $10.10 per share from the trust in connection with the initial business combination, subject to specified limitations. If no business combination is completed by July 16, 2026, Plum will redeem public shares and liquidate, leaving warrants worthless. The filing highlights extensive risks, including high redemption levels, competition among SPACs, macroeconomic and geopolitical instability, regulatory reviews such as potential CFIUS scrutiny, and the risk of being deemed an investment company.

Plum Acquisition Corp. entered into a Business Combination Agreement to merge (the "Merger") with Controlled Thermal Resources Holdings Inc., with Plum IV to domesticate to Delaware prior to Closing. The deal contemplates an earnout of up to 100,000,000 shares, a minimum Available Closing Cash threshold of $100,000,000, a committed PIPE of at least $15,000,000, and a bridge note financing target of $10,000,000.

The post-Closing company will list Domesticated Purchaser Common Stock and Warrants on Nasdaq or NYSE, adopt an Equity Incentive Plan with an initial reserve of approximately 10% of common stock (fully diluted) and a 2.5% annual evergreen, and establish a five-member Post-Closing Board largely designated by the Company. Closing is subject to shareholder approvals, SEC effectiveness of the Registration Statement, exchange listing approval, HSR clearance, and other customary conditions.

Plum Acquisition Corp. IV has signed a Business Combination Agreement to merge with Controlled Thermal Resources Holdings Inc., turning the SPAC into a Delaware corporation whose business will be operated through Controlled Thermal Resources.

Before closing, Plum IV will domesticate from the Cayman Islands to Delaware, convert its Class A and B ordinary shares and warrants into common stock and new warrants, and give Class A holders a chance to redeem their shares. At closing, Class B shares will convert into common stock, and the combined company’s shares and warrants are expected to trade on a major U.S. exchange.

Company stockholders can earn up to 100,000,000 additional shares over ten years through an earnout structure. Conditions include at least $100,000,000 of available closing cash, potential PIPE investments of at least $15,000,000, a $10,000,000 convertible bridge note financing, and issuance of up to 2,000,000 shares to non‑redeeming SPAC holders. An equity incentive plan equal to about 10% of fully diluted shares, with a 2.5% annual “evergreen” increase, and lock-up and registration rights agreements will govern post-closing ownership and liquidity.

Plum Acquisition Corp. IV reports a definitive business combination agreement to combine with Controlled Thermal Resources Holdings Inc. The agreement contemplates that CTR would become a public company through the merger and that the combined company is expected to be listed on Nasdaq. The parties intend to file a Form S-4 registration statement, which will include a preliminary proxy statement/prospectus; after the Registration Statement is declared effective, a definitive proxy statement and related materials will be mailed to Plum IV shareholders for a vote. The disclosure emphasizes forward-looking statements and enumerates customary risks, including the possibility the transaction may not close, listing risks, regulatory and operational risks for CTR’s Hell’s Kitchen project, and other factors described in Plum IV’s SEC filings.

Plum Acquisition Corp. IV announced it has entered into a definitive business combination agreement with Controlled Thermal Resources Holdings Inc. (CTR), an emerging U.S. developer of geothermal power and critical minerals. The deal would make CTR a public company listed on Nasdaq under the ticker “CTRH”.

CTR’s Hell’s Kitchen Project in California is designed to supply up to 650 MW of renewable baseload power and about 100,000 metric tons per year of lithium carbonate at full scale, plus large volumes of potash and other critical minerals. CTR has raised over US$285 million in private capital, completed a definitive feasibility study for Stage 1, secured a conditional use permit, and invested about $185 million in long‑lead equipment. The transaction, unanimously approved by both boards, is expected to close in the second half of 2026, subject to shareholder approvals, regulatory clearances, and other customary conditions, with a pro forma enterprise value of roughly $4.7 billion and CTR holders expected to own about 90.6% of the combined company.
