Plum Acquisition Corp. IV (PLMK) furnished an updated investor presentation about its previously announced proposed business combination with Controlled Thermal Resources Holdings Inc. The materials outline CTR’s Hell’s Kitchen geothermal and critical minerals project in California’s Salton Sea region and the contemplated post‑merger profile.

CTR describes a staged “power‑first” plan targeting 50 MW of Stage 1 baseload geothermal power with remaining capital expenditure of about $475 million and targeted final investment decision in Q2 2027, followed by commercial operation in Q4 2028. A co‑located Stage 1 lithium facility is described at 25,000 TPA capacity with about $1.5 billion of capital, a targeted FID in Q1 2028, and targeted commercial operation in Q4 2030.

At full multi‑stage build‑out, the project is presented as having potential for roughly 650 MW of baseload power and about 100,000 TPA lithium, plus longer‑term upside from potash and other critical minerals. The presentation also includes an illustrative pro forma enterprise value of about $3.34 billion for the combined company and a multi‑step financing plan, all subject to completion of definitive agreements, shareholder and regulatory approvals, financing, and other customary closing conditions. The information is furnished under Regulation FD and characterized as forward‑looking.

Plum Acquisition Corp. IV is a SPAC that has not yet begun operating activities and is focused on completing a business combination. As of June 30, 2026, it held $184.4 million in a Trust Account and reported total assets of $184.8 million.

For the six months ended June 30, 2026, Plum IV recorded net income of $1.8 million, driven by $3.1 million of interest on Trust investments, partially offset by $1.4 million of general and administrative expenses. A working capital deficit of $1.4 million and a deadline to complete a deal by January 16, 2027 led management to state substantial doubt about its ability to continue as a going concern.

The company entered into a Business Combination Agreement with Controlled Thermal Resources Holdings Inc. and later amended it, reducing the implied valuation from $4.5 billion to $3.15 billion and cutting potential earnout shares from 100 million to 70 million, while extending the outside closing date to April 30, 2027. In July 2026, shareholders approved an extension of the combination deadline and redeemed 13,540,384 public shares for about $145 million, leaving approximately $39.7 million in the Trust Account and significantly reducing the public float.
