Item 1.01. Entry into a Material Definitive Agreement.

As previously disclosed,

on March 8, 2026, Plum Acquisition Corp. IV, a Cayman Islands exempted company (which will transfer by way of continuation from the Cayman

Islands to the State of Delaware and domesticate as a Delaware corporation prior to the Closing (as defined below)) (“Plum IV”),

Plum IV Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of Plum IV (“Merger Sub”), and

Controlled Thermal Resources Holdings Inc., a Delaware corporation (the “Company”) entered into a Business Combination

Agreement (the “Business Combination Agreement”, and the transactions contemplated thereby, the “Transactions”),

pursuant to which, among other things and subject to the terms and conditions contained therein, Merger Sub will merge with and into the

Company, with the Company continuing as the surviving company.

On May 15, 2026, Plum

IV, the Company and Merger Sub entered into an amendment to the Business Combination Agreement (the “BCA Amendment”),

which amends the Business Combination Agreement to, among other things, (i) extend the date by which the Company is required to deliver

financial statements and pro forma financial information of the Company required to be included in the proxy statement/prospectus from

May 15, 2026 to June 15, 2026 and June 30, 2026, respectively; (ii) extend the date by which Plum IV, the Company and Merger Sub are required

to make any filings or applications required under antitrust laws with respect to the Transactions from April 17, 2026 to July 31, 2026;

and (iii) extend the dates by which the Company is required to deliver certain material consents from May 7, 2026 to the dates listed

on Schedule 8.01(m) to the Business Combination Agreement.

The foregoing description

of the form of the BCA Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the

BCA Amendment, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K (“Current Report”), and

incorporated herein by reference.

Additional Information

and Where to Find It

In connection with the

Transactions, Plum IV and the Company intend to file with the SEC a registration statement on Form S-4 (the “Registration Statement”),

which will include a preliminary proxy statement of Plum IV as well as a preliminary prospectus relating to the offer of securities to

be issued to the stockholders of the Company (the “Proxy Statement/Prospectus”). After the Registration Statement

is declared effective, a definitive proxy statement and other relevant documents will be mailed to shareholders of Plum IV as of the

record date to be established for voting on the Transactions and other matters as described in the Proxy Statement/Prospectus. Plum IV

will also file other documents regarding the Transactions with the SEC. This Current Report does not contain all of the information that

should be considered concerning the Transactions and is not intended to form the basis of any investment decision or any other decision

in respect of the Transactions. BEFORE MAKING ANY VOTING OR INVESTMENT DECISION, SHAREHOLDERS OF PLUM IV AND OTHER INTERESTED PARTIES

ARE URGED TO READ, WHEN AVAILABLE, THE PRELIMINARY PROXY STATEMENT/PROSPECTUS, AND AMENDMENTS THERETO, AND THE DEFINITIVE PROXY STATEMENT/PROSPECTUS

AND ALL OTHER RELEVANT DOCUMENTS FILED OR THAT WILL BE FILED WITH THE SEC IN CONNECTION WITH PLUM IV’S SOLICITATION OF PROXIES

FOR THE EXTRAORDINARY GENERAL MEETING OF ITS SHAREHOLDERS TO BE HELD TO APPROVE THE TRANSACTIONS AND OTHER MATTERS AS DESCRIBED IN THE

PROXY STATEMENT/PROSPECTUS BECAUSE THESE DOCUMENTS WILL CONTAIN IMPORTANT INFORMATION ABOUT PLUM IV, the Company AND THE TRANSACTIONS.

Investors and security holders will also be able to obtain copies of the Registration Statement and the Proxy Statement/Prospectus and

all other documents filed or to be filed with the SEC by Plum IV, without charge, once available, on the SEC’s website at www.sec.gov

or by directing a request to: Plum Acquisition Corp. IV, 2021 Fillmore St., #2089, San Francisco, California 94115, Attention: Kanishka

Roy, or by email at plumir@icrinc.com.

Participants in

the Solicitation

Plum IV, the Company

and their respective directors and executive officers may be deemed participants under SEC rules in the solicitation of proxies from Plum

IV’s shareholders in connection with the Transactions. A list of the names of such directors and executive officers and information

regarding their interests in the Transactions and their ownership of Plum IV’s securities is, or will be, contained in Plum IV’s

filings with the SEC. Additional information regarding the interests of the persons who may, under SEC rules, be deemed participants in

the solicitation of proxies from Plum IV’s shareholders in connection with the Transactions, including the names and interests of

the Company’s directors and executive officers, will be set forth in the Proxy Statement/Prospectus, which is expected to be filed

by Plum IV and the Company with the SEC. Investors and security holders may obtain free copies of these documents as described above.

No Offer or Solicitation

This Current Report is

for informational purposes only and is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any

securities or in respect of the Transactions and shall not constitute an offer to sell or exchange, or a solicitation of an offer to buy

or exchange the securities of Plum IV or the Company, or any commodity or instrument or related derivative, nor shall there be any sale

of any such securities in any state or jurisdiction in which such offer, solicitation, sale or exchange would be unlawful prior to registration

or qualification under the securities laws of any such state or jurisdiction. This Current Report is not, and under no circumstances is

to be construed as, a prospectus, an advertisement or a public offering of the securities described herein in the United States or any

other jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act

or an exemption therefrom. Investors should consult with their counsel as to the applicable requirements for a purchaser to avail itself

of any exemption under the Securities Act.

Forward-Looking

Statements

This Current Report and

the exhibits attached hereto contain certain forward-looking statements within the meaning of the U.S. federal securities laws with

respect to the Transactions and the parties thereto. All statements contained in this Current Report other than statements of historical

fact, including, without limitation, statements regarding the Transactions between Plum IV and the Company; the anticipated benefits and

timing of the Transactions; expected trading of the combined company’s securities on the Nasdaq; the building of the Company’s

flagship Hell’s Kitchen Project; the anticipated benefits and timing of the Company’s flagship Hell’s Kitchen Project,

the combined company’s future financial performance; the ability of the combined company to execute its business strategy, its market

opportunity and positioning; and other statements regarding management’s intentions, beliefs, or expectations with respect to the

combined company’s future performance, are forward-looking statements.

Forward-looking statements

are often identified by the use of words such as “anticipate,” “believe,” “continue,” “could,”

“estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,”

“predict,” “project,” “should,” “will,” “would,” and similar expressions,

but the absence of these words does not mean that a statement is not forward-looking.

These forward-looking

statements are based on the current expectations and assumptions of Plum IV and the Company and are subject to risks and uncertainties

that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. Such risks and

uncertainties include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to

the termination of the Business Combination Agreement; (2) the outcome of any legal proceedings that may be instituted against the parties

following the announcement of the Transactions and any definitive agreements with respect thereto; (3) the inability to complete the Transactions,

including due to failure to obtain approval of the shareholders of Plum IV and the Company or other conditions to closing; (4) the risk

that the Transactions may not be completed by Plum IV’s business combination deadline and the potential failure to obtain an extension

of the business combination deadline if sought by Plum IV; (5) the inability to maintain the listing of Plum IV’s securities or

to obtain or maintain the listing of the combined company’s securities on the Nasdaq, the New York Stock Exchange, or another national

securities exchange following the Transactions; (6) the risk that the Transactions disrupts the Company’s current plans, business

relationships, performance, operations and business generally as a result of the announcement and consummation of the Transactions; (7)

the risk that the price of the combined company’s securities may be volatile due to a variety of factors, including changes in laws,

regulations, technologies, natural disasters, geopolitical tensions, and macro-economic and social environments affecting its business;

(8) the ability to recognize the anticipated benefits of the Transactions, which may be affected by, among other things, competition,

the ability of the combined company to grow and manage growth profitably and retain its key employees; (9) costs related to the Transactions;

(10) changes in applicable laws or regulations; (11) risks related to the Company’s business, including fluctuations in demand and

prices for lithium and other critical minerals, competition within the industry, the risks inherent in development projects and exploration

activities, potential delays or cost overruns in capital expenditures, the ability to secure necessary raw materials, compliance with

regulatory requirements, environmental and safety obligations, economic and market conditions, and political or geopolitical developments;

and (12) other risks detailed from time to time in Plum IV’s filings with the SEC, including the Registration Statement and related

documents filed or to be filed in connection with the Transactions.

The foregoing list

of risk factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties

described in the “Risk Factors” section of Plum IV’s Annual Report on Form 10-K filed with the SEC on March 31,

2026, Plum IV’s Quarterly Report on Form 10-Q filed with the SEC on May 15, 2026, subsequent Quarterly Reports on Form 10-Q and the

Registration Statement and Proxy Statement/Prospectus that will be filed by Plum IV and the Company, and other documents filed by

Plum IV from time to time with the SEC, as well as the list of risk factors included herein. These filings identify and address

other important risks and uncertainties that could cause actual results to differ materially from those contained in the

forward-looking statements. Additional risks and uncertainties not currently known or that are currently deemed immaterial may also

cause actual results to differ materially from those expressed or implied by such forward-looking statements. Readers are cautioned

not to put undue reliance on forward-looking statements, and none of the parties or any of their representatives assumes any

obligation and do not intend to update or revise these forward-looking statements, each of which is made only as of the date of this

Current Report.

“Section

6.04 Annual and Interim Financial Statements. As soon as reasonably practicable

following the date of this Agreement, but in no event later than June 15, 2026, the Company shall deliver to the Purchaser audited balance

sheet and statement of operations, comprehensive loss, stockholders’ equity and cash flows of the Company as of and for the years

ended December 31, 2024 and 2025, together with the auditor’s reports thereon and which comply in all material respects with the

to a registrant (excluding pro forma financial information, which shall be delivered by the Company to the Purchaser no later than June

30, 2026) in such form as required by the applicable rules and regulations of the SEC and which have been reviewed or audited, as applicable,

in accordance with GAAP and PCAOB standards (collectively, the “PCAOB Financial Statements”); provided, that

upon delivery of such PCAOB Financial Statements, such financial statements shall be deemed “Company Financials” for the

purposes of this Agreement. In addition, as soon as reasonably practicable following the date of this Agreement, but in no event later

than June 15, 2026, the Company shall deliver to the Purchaser unaudited financial statements of the Company as of and for the quarter

“(b)

In furtherance and not in limitation of Section 6.09(a), to the extent required under the HSR Act any other Laws that are

filing or application under Antitrust Laws, as applicable, at such Party’s sole cost and expense (except that any fees or other

amounts charged by any Governmental Authorities relating to such filings or applications by the Company or the Purchaser under

Antitrust Laws will be paid by the Company and borne 50% by the Company as a Company Transaction Cost and 50% by the Purchaser as a

Purchaser Transaction Cost), with respect to the Transactions as promptly as practicable (but in no event later than July 31, 2026,

except as mutually agreed otherwise by the Parties), to supply as promptly as reasonably practicable any additional information and

including by requesting early termination of the waiting period provided for under the HSR Act or any other Antitrust Laws and

obtaining any approval required under any other Antitrust Laws; provided, that neither Party shall extend any waiting period

under the HSR Act or comparable period under any other Antitrust Laws or enter into any agreement with any Governmental Authority to

so extend such waiting period or comparable period without the prior written consent of the other Parties. Each Party shall, in connection with its efforts to obtain all requisite approvals and authorizations for

the Transactions under any Antitrust Law, use its reasonable best efforts to: (i) cooperate in all respects with each other Party or its

Affiliates in connection with any filing or submission and in connection with any investigation or other inquiry, including any proceeding

initiated by a private Person; (ii) keep the other Parties reasonably informed of any material communication received by such Party or

its Representatives from, or given by such Party or its Representatives to, any Governmental Authority and of any communication received

or given in connection with any proceeding by a private Person, in each case regarding any of the Transactions; (iii) permit a Representative

of the other Parties and their respective outside counsel to review any material communication given by it to, and consult with each other

in advance of any meeting or conference with, any Governmental Authority or, in connection with any proceeding by a private Person, with

any other Person, and unless prohibited by such Governmental Authority or other Person, give a Representative or Representatives of the

other Parties the opportunity to attend and participate in such meetings and conferences; (iv) in the event a Party’s Representative is

prohibited from participating in or attending any meetings or conferences, the other Parties shall keep such Party promptly and reasonably

apprised with respect thereto; and (v) use reasonable best efforts to cooperate in the filing of any memoranda, white papers, filings,

correspondence or other written communications explaining or defending the Transactions, articulating any regulatory or competitive argument,

and/or responding to requests or objections made by any Governmental Authority. The Parties agree that any written materials of such Party

(including without limitation any notification and report forms filed under the HSR Act concerning the Transactions) may be redacted or

disclosed for outside counsel only, as necessary to comply with contractual arrangements and as necessary to address reasonable privilege

or confidentiality concerns, in each event prior to sharing such materials with another Party.”

“(m) by the Purchaser if the

Company has not delivered the Consents and Contracts described on Schedule 8.01(m) (the “Material Consents”) by the dates

set forth on Schedule 8.01(m); provided, that the Purchaser shall not have the right to terminate this Agreement pursuant to this

Section 8.01(m) if at such time the Purchaser is in material uncured breach of this Agreement.”
