~~Item~~On March 116, 2026, IB Acquisition Corp.01, ~~Entry~~a Nevada corporation (“IB Acquisition”), and GNQ Insilico Inc., a corporation formed under the federal laws of Canada (“GNQ”), entered into a ~~Material~~Business ~~Definitive~~Combination Agreement (the “BCA”). Unless otherwise defined herein, capitalized terms used in this Current Report on Form 8-K have the meanings ascribed to them in the Business Combination Agreement. Pursuant to the BCA and by means of an arrangement under Section 192 of the Canada Business Corporations Act (the “Arrangement”), subject to the terms and conditions set forth in the BCA and a plan of arrangement (the “Plan of Arrangement”) to be submitted to the Ontario Superior Court of Justice (Commercial List) (the “Court”), upon the closing of the transactions contemplated by the BCA (the “Closing”), the GNQ Shareholders will receive the following consideration in exchange for their respective shares of capital stock of GNQ:

As approved by the Company’s stockholders at a special meeting held on September 22, 2025 (the “Special Meeting”) the Company entered into Amendment No. 1 (the “Trust Amendment”) to the Investment Management Trust Agreement, dated as of March 25, 2024, with Continental Stock Transfer & Trust Company, as trustee (the “Trustee”).

●	For each share of GNQ common stock (the “Company Common Shares”) held by eligible electing Canadian shareholders of GNQ (“Electing Shareholders”), the Electing Shareholder will receive a number of exchangeable shares in an indirect, wholly owned Canadian subsidiary of IB Acquisition (the “ExchangeCo Shares”) equal to the quotient obtained by dividing 50,000,000 by the Fully-Diluted Company Common Shares (as defined below) (the “Company Exchange Ratio”); and

●	For each share of Company Common Shares held by all other shareholders of GNQ (“Non-Electing Shareholders”, and collectively with the Electing Shareholders, the “GNQ Shareholders”), such Non-Electing Shareholder will exchange their respective Company Common Shares for shares of SPAC Class A Common Stock equal to the Company Exchange Ratio (the “Company U.S. Shareholder Exchange” and, together with the other exchanges and subscriptions described above, the “Share Exchanges”).

~~Pursuant~~The to“Arrangement ~~the~~Consideration” ~~Amendment,~~means ~~Section 1(i) of~~ the ~~Trust~~sum Agreement was amended and restated to authorize the Company to extend the deadline by which it must consummate its initial business combination by an additional six (6) months from September 28, 2025 to March 28, 2026.

As approved by the Company’s stockholders at the Special Meeting, the Company adopted a First Amendment to its Amended and Restated Articles of Incorporation (the “Extension Amendment”). The Extension Amendment, among other things, (i) extends the date by which the Company must consummate its initial business combination to March 28, 2026 or such later date as may be approved by the Company’s stockholders in accordance with its amended and restated articles of incorporation; (ii) provides that, prior to the earliest of the completion of a business combination, the redemption of 100% of the Offering Shares if the Company is unable to complete its initial Business Combination by March 28, 2026, and the redemption of shares in connection with a vote seeking to amend any provisions of the Company’s Amended and Restated Articles relating to stockholders’ rights or any pre-initial Business Combination activity, funds in the Company’s trust account will not be released, other than interest to pay franchise and income taxes; (iii) sets forth the redemption and liquidation procedures if the Company does not consummate a business combination by the March 28, 2026; and (iv) provides public stockholders with the right to redeem their shares in connection with any amendment that modifies the substance or timing of the Company’s obligation to redeem 100% of the public shares if it has not consummated a business combination by March 28, 2026, or with respect to other material pre-business combination provisions, subject to the applicable redemption limitation.1

GNQ agreed that it and its affiliates will not have any right, title, interest or claim of any kind in or to any monies in IB Acquisition’s trust account held for its public stockholders, and agreed not to, and waived any right to, make any claim against the trust account (including any distributions therefrom).

~~SIGNATURES~~The BCA is filed as Exhibit 2.1 to this Current Report on Form 8-K and the foregoing description thereof is qualified in its entirety by reference to the full text of the BCA. The BCA provides investors with information regarding its terms and is not intended to provide any other factual information about the parties. In particular, the assertions embodied in the representations and warranties contained in the BCA were made as of the execution date of the BCA only and are qualified by information in confidential disclosure schedules provided by the parties to each other in connection with the signing of the BCA. These disclosure schedules contain information that modifies, qualifies, and creates exceptions to the representations and warranties set forth in the BCA. Moreover, certain representations and warranties in the BCA may have been used for the purpose of allocating risk between the parties rather than establishing matters of fact. Accordingly, you should not rely on the representations and warranties in the BCA as characterizations of the actual statements of fact about the parties.

Side Letter Agreement

Concurrently with the execution of the BCA, the Company has also entered into a letter agreement (the “Side Letter Agreement”) with IBAC pursuant to which the Company will complete a debt financing of 10% secured convertible promissory notes (“Convertible Notes”) and common share purchase warrants (“Warrants”) for aggregate gross proceeds of up to US$2,000,000 (the “Bridge Financing”). In connection with the execution of the BCA, an investor introduced by IBAC purchased a Convertible Note for US$250,000 in aggregate principal amount of Convertible Notes. The Convertible Notes accrue on the outstanding principal balance at a rate of 10% per annum, calculated on the basis of a 360-day year and expire in six months from the date of issuance. At any time while the Convertible Notes remain outstanding, the holders may, at their option, elect to convert all or any portion of the aggregate principal amount outstanding under the Convertible Notes, together with any accrued and unpaid interest owing thereon, into that number of common shares in the capital of GNQ (“Company Common Shares”) as is equal to the quotient of (a) the aggregate principal amount outstanding under the Convertible Notes, together with any accrued and unpaid interest owing thereon as of the date immediately prior to conversion, divided by (b) a price per Company Common Share equal to 80% of the deemed price per Company Common Share as adjusted pursuant to the exchange ratio set forth in the BCA (the “Conversion Price”).

Each Convertible Note shall be accompanied by a five-year Warrant to purchase Company Common Shares, with the number of Company Common Shares determined by dividing (a) 100% of the principal amount of the Convertible Notes by (b) an assumed value for a Company Common Share to be agreed upon by the parties based on a discount to the US$10.00 reference value of a share of SPAC Class A Common Stock as set forth in the BCA. The Warrants are exercisable for a period of five years from the date of issuance, provided that, in the event that the Transaction is effected in advance of such expiry date, immediately prior to the effective time of the Transaction, the holders may elect to exercise the Warrants into Company Common Shares on a cashless basis. The exercise price under the Warrants will be equal to the Conversion Price.

The Side Letter Agreement, form of Convertible Note, and form of Warrant are filed as Exhibits 10.1, 10.2, and 10.3, respectively, to this Current Report on Form 8-K, and the foregoing description thereof is qualified in its entirety by reference to the full text of the letter agreement, form of Convertible Note, and form of Warrant.

Shareholder Support Agreement

Contemporaneously with the execution of the BCA, IB Acquisition, GNQ and certain GNQ shareholders entered into a Shareholder Support Agreement, pursuant to which, among other things, the GNQ shareholders party to such agreement agreed (i) to vote their GNQ shares in favor of the Arrangement and other resolutions needed to consummate the Arrangement and the other Transactions, and, subject to limited exceptions, to not transfer such shares, and (ii) to waive, and not to exercise, any dissent rights for GNQ shares in connection with the Arrangement. The GNQ shareholders party to the Shareholder Support Agreement collectively have a sufficient number of votes to approve the Arrangement.

The Shareholder Support Agreement and all of its provisions will terminate and be of no further force or effect upon the earlier of (i) the Closing, (ii) termination of the BCA pursuant to its terms, and (iii) a Company Modification in Recommendation made in connection with a Superior Proposal. Upon such termination of the Shareholder Support Agreement, all obligations of the parties under the Shareholder Support Agreement will terminate; provided, however, that such termination will not relieve any party thereto from liability arising in respect of any breach of the Shareholder Support Agreement prior to such termination.

The Shareholder Support Agreement is filed as Exhibit 10.4 to this Current Report on Form 8-K, and the foregoing description thereof is qualified in its entirety by reference to the full text of the Shareholder Support Agreement.

Sponsor Support Agreement

Contemporaneously with the execution of the BCA, IB Acquisition entered into a Sponsor Support Agreement with the Sponsor and GNQ, pursuant to which, among other things, the Sponsor agreed (i) to vote its shares of SPAC Capital Stock in favor of the BCA and each of the Transaction Proposals, and to not transfer such shares, (ii) not to redeem any of its shares of IB Acquisition capital stock in connection with the Transactions, (iii) to waive its anti-dilution rights with respect to its shares of IB Acquisition common stock, under the IB Acquisition amended and restated articles of incorporation, and (iv) to subject certain of its shares of IB acquisition common stock to additional transfer restrictions and other conditions set forth in the Sponsor Support Agreement.

The Sponsor Support Agreement and certain of its provisions will terminate and be of no further force or effect upon the earlier to occur of Closing and termination of the BCA pursuant to its terms and, if the BCA is terminated pursuant to its terms, all provisions of the Sponsor Support Agreement will terminate and be of no further force or effect.

The Sponsor Support Agreement is filed as Exhibit 10.5 to this Current Report on Form 8-K, and the foregoing description thereof is qualified in its entirety by reference to the full text of the Sponsor Support Agreement.

Lock-Up Agreement

Prior to the Closing, IB Acquisition will enter into separate Lock-Up Agreements (each a “Lock-Up Agreement”) with a number of GNQ shareholders and Sponsor pursuant to which the securities of IB Acquisition and ExchangeCo held by such holders will be locked-up and subject to transfer restrictions for a period of time following the Closing, as described below, subject to certain exceptions. The securities held by such GNQ shareholders will be locked-up until the earlier of: (i) six (6) months after the date of the Closing, and (ii) subsequent to the Closing, the date on which SPAC consummates a liquidation, merger, capital stock exchange, reorganization, or other similar transaction that results in all of SPAC’s stockholders having the right to exchange their SPAC Common Stock for cash, securities or other property; provided, that if the closing trading price of the SPAC Common Stock on the stock exchange on which the SPAC Common Stock is listed exceeds US$12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 Trading Days within any 30-day Trading Day period, then Holder shall have the right to sell 50% of its SPAC Common Stock subject to applicable regulatory restrictions, and if the closing trading price of the SPAC Common Stock on the stock exchange on which the SPAC Common Stock is listed exceeds US$15.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 Trading Days within any 30-day Trading Day period, then Holder shall have the right to sell an the remaining 50% of its SPAC Common Stock subject to applicable regulatory restrictions.

A form of the Lock-Up Agreement is filed as Exhibit 10.6 to this Current Report on Form 8-K, and the foregoing description thereof is qualified in its entirety by reference to the full text of the Lock-Up Agreement.

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding the proposed transaction between IB Acquisition and GNQ. Such forward-looking statements include, but are not limited to, statements regarding the closing of the transaction and IB Acquisition’s, GNQ’s, or their respective management teams’ expectations, hopes, beliefs, intentions or strategies regarding the future. The words “anticipate”, “believe”, “continue”, “could”, “estimate”, “expect”, “intends”, “may”, “might”, “plan”, “possible”, “potential”, “predict”, “project”, “should”, “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. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. These statements are based on various assumptions, whether or not identified in this Current Report on Form 8-K. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied on by an investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of IB Acquisition and GNQ. Many factors could cause actual future events to differ from the forward-looking statements in this Current Report on Form 8-K, including but not limited to, (i) the risk that the transaction may not be completed in a timely manner or at all, (ii) the failure to satisfy the conditions to the consummation of the transaction, including the approval by the stockholders of IB Acquisition, the satisfaction of the minimum trust account amount following any redemptions by IB Acquisition’s public stockholders and the receipt of certain governmental and regulatory approvals, (iii) risks related to the timing, outcome, and scope of review by the SEC of the registration statement on Form S-4, (iv) the inability to complete the PIPE offering, (v) the occurrence of any event, change or other circumstance that could give rise to the termination of the business combination agreement entered into by IB Acquisition and GNQ, (vi) the outcome of any legal proceedings that may be instituted against IB Acquisition and/or GNQ related to the business combination agreement entered into by IB Acquisition and GNQ or the transactions contemplated thereby, (vii) the ability to maintain the listing of IB Acquisition’s stock on Nasdaq (or, if applicable, to list and maintain the listing of the combined entity on the NYSE), (viii) volatility in the price of IB Acquisition’s securities, (ix) costs related to the transactions and the failure to realize anticipated benefits of the transactions or to realize estimated pro forma results and underlying assumptions, including with respect to estimated stockholder redemptions, (x) the effect of the announcement or pendency of the transaction on GNQ’s business relationships, operating results, performance and business generally, (xi) risks that the transactions disrupt current plans and operations of GNQ, (xii) changes in the combined capital structure of IB Acquisition and GNQ following the transactions, (xiii) changes in the competitive industries and markets in which GNQ operates or plans to operate, (xiv) changes in laws and regulations affecting GNQ’s business, (xv) the ability to implement business plans, forecasts, and other expectations after the completion of the transactions, and identify and realize additional opportunities, (xvi) risks related to the uncertainty of GNQ’s projected financial information, (xvii) risks related to GNQ’s limited operating history, the rollout of its business and the timing of expected business milestones, (xviii) risks related to GNQ’s potential inability to achieve or maintain profitability and generate cash, (xix) current and future conditions in the global economy, and their impact on GNQ, its business and markets in which it operates, (xx) the ability of GNQ to retain existing customers and attract new customers, (xxi) the potential inability of GNQ to manage growth effectively, (xxii) the enforceability of GNQ’s intellectual property, including its patents and the potential infringement on the intellectual property rights of others, and (xxiii) the ability to recruit, train and retain qualified personnel. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of IB Acquisition’s Form S-1 Registration Statement filed with the SEC on March 27, 2024, IB Acquisition’s Form 10-K filed on December 29, 2025, the Form S-4 Registration Statement that IB Acquisition will file, which will include a proxy statement/prospectus, and other documents filed or to be filed by IB Acquisition from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and IB Acquisition and GNQ assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. Neither IB Acquisition nor GNQ gives any assurance that either IB Acquisition or GNQ will achieve its expectations.
