Postponement

of Extraordinary General Meeting

June 16, 2026, Plum Acquisition Corp. IV (the “Company”) filed a definitive proxy statement (the “Extension Proxy

Statement”) for an extraordinary general meeting (the “Shareholder Meeting”) of its shareholders originally

scheduled to be held on July 2, 2026, at 9:00 a.m., Eastern Time, to approve, among other things, an amendment to the

Company’s amended and restated memorandum and articles of association to amend the date by which the Company must consummate

an initial business combination (the “Extension Amendment Proposal”) to January 16, 2027 (or up to July 16, 2027, if all

6 additional monthly extensions are exercised), or such earlier date as determined by the Company’s board of directors, in its

sole discretion (the “Amendment”). Defined terms used but not defined herein have the meanings set forth in the

Extension Proxy Statement.

The

Company has decided to postpone the Shareholder Meeting to July 10, 2026, at 9:00 a.m., Eastern Time, to allow additional time for

the Company to engage with shareholders. As a result of the postponement of the Shareholder Meeting, the Company has extended the

deadline for delivery of redemption requests from the Company’s shareholders from 5:00 p.m., Eastern Time, on June 30, 2026,

to 5:00 p.m., Eastern Time, on July 8, 2026.

The

postponed meeting will be held on July 10, 2026, at 9:00 a.m., Eastern Time, at the offices of Greenberg Traurig, P.A., located at 777

S. Flagler Drive, Suite 300 East, West Palm Beach, FL 33401. If you wish to attend the Shareholder Meeting in person, you must reserve

your attendance at least two business days in advance of the Shareholder Meeting by contacting the Company’s Chief Financial Officer

at steven@plumpartners.com by 9:00 a.m., Eastern Time, on July 8, 2026 (two business days prior to the newly scheduled meeting date).

Shareholders

who hold their investments through a bank or broker, will need to contact the Company’s transfer agent to receive a control

number. If you plan to vote at the Shareholder Meeting you will need to have a legal proxy from your bank or broker or if you would

like to join and not vote, the transfer agent will issue you a guest control number with proof of ownership. Either way you must

contact the transfer agent for specific instructions on how to receive the control number. The transfer agent can be contacted at

917-262-2373, or via email at proxy@continentalstock.com. Please allow up to 72 hours prior to the meeting for processing your

control number.

On June 29, 2026, the Company issued a press release announcing the postponement of the Shareholder Meeting, a copy of which is attached

as Exhibit 99.1 to this Current Report on Form 8-K (the “Current Report”).

Cautionary

Note Regarding Forward-Looking Statements

This

Current Report contains statements that are forward-looking and as such are not

historical facts. This includes, without limitation, statements regarding the Company’s financial position, business strategy

and the plans and objectives of management for future operations. These statements constitute projections, forecasts and

forward-looking statements, and are not guarantees of performance. They involve known and unknown risks, uncertainties, assumptions

and other factors that may cause the actual results, performance or achievements of the Company to be materially different from any

future results, performance or achievements expressed or implied by these statements. Such statements can be identified by the fact

that they do not relate strictly to historical or current facts. When used in this Current Report, words such as

“anticipate,” “believe,” “continue,” “could,” “estimate,”

“expect,” “intend,” “may,” “might,” “plan,” “possible,”

“potential,” “predict,” “project,” “should,” “strive,”

“would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean

that a statement is not forward-looking. These forward-looking statements involve a number of risks, uncertainties (some of which

are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those

expressed or implied by these forward-looking statements. When the Company discusses its strategies or plans, it is making

projections, forecasts or forward-looking statements. Such statements are based on the beliefs of, as well as assumptions made by

and information currently available to, the Company’s management. Actual results and shareholders’ value will be

affected by a variety of risks and factors, including, without limitation, international, national and local economic conditions,

merger, acquisition and business combination risks, financing risks, geo-political risks, acts of terror or war, and those risk

factors described under the “Risk Factors” section of the Company’s Annual Report on Form 10-K filed with the

Securities and Exchange Commission (the “SEC”) on March 31, 2026, the Company’s Quarterly Report on Form 10-Q

filed with the SEC on May 15, 2026, subsequent Quarterly Reports on Form 10-Q, in the Extension Proxy Statement filed in connection

with the Shareholder Meeting and Amendment on June 16, 2026 and in other reports the Company files with the SEC. Many of the risks

and factors that will determine these results and shareholders’ value are beyond the Company’s ability to control or

predict.

All

such forward-looking statements speak only as of the date of this Current Report. The Company expressly disclaims any obligation or undertaking

to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in the Company’s

expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based. All subsequent

written or oral forward-looking statements attributable to us or persons acting on the Company’s behalf are qualified in their

entirety by this “Cautionary Note Regarding Forward-Looking Statements” section.

Company and its directors and executive officers may be deemed participants under SEC rules in the solicitation of proxies from the Company’s
