INVESTMENT MANAGEMENT TRUST AGREEMENT

This Amendment No. 1 (this “Amendment”), dated as of September 22, 2025, to the Investment Management Trust Agreement (the “Trust Agreement”) is made by and between IB Acquisition Corp. (the “Company”) and Continental Stock Transfer & Trust Company, as trustee (“Trustee”). All terms used but not defined herein shall have the meanings assigned to them in the Trust Agreement.

WHEREAS, the Company and the Trustee entered into the Trust Agreement on March 25, 2024;

WHEREAS, Section 1(i) of the Trust Agreement sets forth the terms that govern the liquidation of the Trust Account under the circumstances described therein; and

WHEREAS, at a special meeting of the Company held on September 22, 2025, the Company’s stockholders approved (i) a proposal to amend the Company’s Amended and Restated Articles of Incorporation (the “A&R AOI”) to authorize the Company to extend the date of September 28, 2025, by six (6) additional months (ultimately until March 28, 2026) by which the Company must (a) consummate a merger, capital stock exchange, asset, stock purchase, reorganization or other similar business combination, which we refer to as our initial business combination, or (b) cease its operations except for the purpose of winding up if it fails to complete such initial business combination, and redeem all of the shares of common stock of the Company included as part of the units sold in the Company’s initial public offering that was consummated on March 28, 2024, and (ii) a proposal to amend the Trust Agreement to authorize the Extension and its implementation by the Company.

NOW THEREFORE, IT IS AGREED:

Section 1(i) of the Trust Agreement is hereby amended and restated in its entirety as follows:

“(i) Commence liquidation of the Trust Account only after and promptly after (x) receipt of, and only in accordance with, the terms of a letter from the Company (“Termination Letter”), in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B, as applicable, signed on behalf of the Company by its Chief Executive Officer, President, Secretary or Chairman of the board of directors of the Company (the “Board”) or other authorized officer of the Company, and, in the case of Exhibit A, acknowledged and agreed to by the Representative, and complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest not previously released to the Company to pay its taxes, only as directed in the Termination Letter and the other documents referred to therein, or (y) upon the date which is the later of (i) March 28, 2026 and (ii) such later date as may be approved by the Company’s stockholders in accordance with the Company’s amended and restated articles of incorporation, if a Termination Letter has not been received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account, including interest not previously released to the Company to pay its taxes shall be distributed to the Public Stockholders of record as of such date. It is acknowledged and agreed that there should be no reduction in the principal amount per share initially deposited in the Trust Account;”

All other provisions of the Trust Agreement shall remain unaffected by the terms hereof.

This Amendment may be signed in any number of counterparts, each of which shall be an original and all of which shall be deemed to be one and the same instrument, with the same effect as if the signatures thereto and hereto were upon the same instrument. A facsimile signature or electronic signature shall be deemed to be an original signature for purposes of this Amendment.

This Amendment is intended to be in full compliance with the requirements for an Amendment to the Trust Agreement as required by Section 6(d) of the Trust Agreement, and every defect in fulfilling such requirements for an effective amendment to the Trust Agreement is hereby ratified, intentionally waived and relinquished by all parties hereto.

This Amendment shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction.

Exhibit B of the Trust Agreement is hereby amended and restated in its entirety as follows:
