Plum Acquisition Corp. announces the preliminary estimated cash redemption price for public shareholders ahead of its upcoming extension vote. Based on approximately $184,528,681.34 held in the Trust Account as of July 9, 2026, the estimated per-share redemption price is about $10.6973 at the time of the shareholder meeting.

The extraordinary general meeting is scheduled for July 10, 2026, where shareholders will vote on extending the SPAC Termination Date from July 16, 2026 to January 16, 2027, with the ability to further extend monthly up to July 16, 2027. Shareholders may elect to redeem or withdraw prior redemption requests up to 9:00 a.m. Eastern Time on the meeting date. The closing market price of the public shares on July 9, 2026 was $10.77 per share.

Plum Acquisition Corp. IV describes plans around an upcoming shareholder vote to extend the deadline for completing its initial business combination. The proposed amendment would move the deadline to January 16, 2027, with up to six additional monthly extensions available through July 16, 2027, if exercised.

In connection with the July 10, 2026 meeting, Class A shareholders have until 5:00 p.m. Eastern on July 8, 2026 to submit redemption requests. The company and its sponsor intend to enter into Non-Redemption Agreements, under which certain unaffiliated holders would agree not to redeem in exchange for a future transfer of sponsor-owned Class B (or converted Class A) shares if the extension is approved and those shares are not redeemed. The sponsor and certain initial holders also plan to convert substantially all Class B shares into Class A shares, which will not be eligible to receive trust account funds and will remain subject to transfer restrictions.

Plum Acquisition Corp. IV is postponing its extraordinary general meeting of shareholders to July 10, 2026, at 9:00 a.m. Eastern Time. At this meeting, shareholders are scheduled to vote on an Extension Amendment Proposal to push the SPAC’s deadline to complete an initial business combination to January 16, 2027, or up to July 16, 2027 if all six additional one-month extensions are exercised. The company also moved the deadline for shareholders to submit redemption requests from June 30, 2026, to July 8, 2026, giving investors more time to decide whether to redeem their shares or remain invested ahead of the extension vote.

Plum Acquisition Corp. IV is asking shareholders to approve an amendment extending the deadline to complete its initial business combination from July 16, 2026 to January 16, 2027, with the ability for the board, at the sponsor’s request, to add up to six one‑month extensions to July 16, 2027 without another vote. The company has signed a Business Combination Agreement with Controlled Thermal Resources Holdings Inc. and says more time is needed to close that deal. Holders of public shares may redeem all or part of their shares for cash from the trust account in connection with the extension vote, while retaining warrant holdings. As of June 12, 2026, the trust account held about $184.1 million, implying an estimated redemption price of roughly $10.67 per public share versus a Nasdaq trading price of $10.61. If the extension is not approved and no business combination is completed by the current deadline, Plum will redeem all public shares and liquidate, leaving warrants worthless.
