Plum Acquisition Corp, IV 8-K

What Happened
Plum Acquisition Corp. IV (Plum IV) announced a second amendment (effective July 6, 2026) to its Business Combination Agreement with Controlled Thermal Resources Holdings Inc. The amendment (the “Second BCA Amendment”) changes multiple economic and timing terms of the proposed merger, and Plum IV and the Company intend to file a Form S-4 (proxy statement/prospectus) with the SEC in connection with the transaction.

Key Details

• Earnout shares reduced from 100,000,000 to 70,000,000 total; each of eight earnout tranches lowered from 12,500,000 to 8,750,000 shares.
• Valuation used to calculate merger consideration cut from $4,500,000,000 to $3,150,000,000.
• Closing deadline extended from December 31, 2026 to April 30, 2027; antitrust filing deadline extended from July 31, 2026 to September 30, 2026.
• Maximum shares reimbursable to Plum Partners IV, LLC for founder-share matters increased from 2,000,000 to 3,000,000; certain consent delivery deadlines also extended per the amended agreement.

Why It Matters
These changes materially alter the economics and timing of the planned merger: the reduction in maximum earnout shares and the lower valuation change the potential equity consideration and possible dilution to Plum IV shareholders, while the extended deadlines (including the closing and antitrust filing dates) give the parties more time to satisfy regulatory and closing conditions but delay completion. Investors should review the upcoming Form S-4 and proxy/prospectus when filed for full details and note that the companies highlighted standard forward‑looking risks related to closing the transaction.
