Item 1.01 Entry into a Material Definitive Agreement.

As previously disclosed, on August 28, 2026, Andretti Acquisition Corp. II, a Cayman Islands exempted company (the "Company"), convened and then determined to adjourn, without conducting any business, its extraordinary general meeting in lieu of an annual meeting (the "Special Meeting") to extend the date by which the Company must consummate a business combination from September 9, 2026 to September 9, 2027 (or such earlier date as may be determined by the Board of Directors of the Company) (such extension, the "Extension") from August 28, 2026 to September 8, 2026 at 10:00 a.m. Eastern Time, in order to extend the period of time for redemptions and reversal of redemptions. In connection with the Special Meeting, on August 28, 2026, August 31, 2026, September 1, 2026 and September 2, 2026, the Company and Andretti Sponsor II LLC (the "Sponsor") entered into non-redemption agreements (the "Prior Non-Redemption Agreements") with several unaffiliated third-party holders (the "Investors") of the Company's Class A ordinary shares, par value $0.0001 per share (the "Class A Ordinary Shares"), issued in the Company's initial public offering (the "Public Shares"), pursuant to which the Company and the Sponsor agreed to cause the surviving entity of any future Company initial business combination ("Pubco") to issue, in connection with the consummation of an initial business combination, to such Investors up to (i) an aggregate of 1,450,000 ordinary or common shares of Pubco ("Pubco Shares") if the initial business combination is completed on or prior to June 9, 2027 and (ii) an aggregate of 483,334 additional Pubco Shares if the initial business combination is completed after June 9, 2027, in exchange for their agreement to not redeem up to an aggregate of 5,800,000 Public Shares (the "Non-Redeemed Shares").

On September 3, 2026, the Company and the Sponsor entered into additional non-redemption agreements with new Investors (the "New Non-Redemption Agreements" and, together with the Prior Non-Redemption Agreements, the "Non-Redemption Agreements"), pursuant to which the Company and the Sponsor agreed to cause Pubco to issue, in connection with the consummation of an initial business combination, such Investors up to (i) an aggregate of 112,240 Pubco Shares if the initial business combination is completed on or prior to June 9, 2027 and (ii) an aggregate of 37,413 additional Pubco Shares if the initial business combination is completed after June 9, 2027, in exchange for its agreement to not redeem up to an aggregate of 448,959 Non-Redeemed Shares. The terms and conditions of the New Non-Redemption Agreement are substantially identical in all material respects to the Prior Non-Redemption Agreements.

The Non-Redemption Agreements are not expected to increase the likelihood that the Extension is approved by the Company's shareholders, but are expected to increase the amount of funds that remain in the Company's trust account established in connection with Company's initial public offering following the Special Meeting. The Company and the Sponsor may enter into additional, similar non-redemption agreements in connection with the Special Meeting.

The Non-Redemption Agreements shall terminate on the earlier of (i) the failure of the Company's shareholders to approve the Extension at the Special Meeting, (ii) the Company's determination not to proceed with the Extension, (iii) the fulfillment of all obligations of parties to the Non-Redemption Agreements, (iv) the liquidation or dissolution of the Company, (v) the mutual written agreement of the parties or (vi) if the applicable Investor exercises its redemption rights with respect to any Non-Redeemed Shares in connection with the Special Meeting and such Non-Redeemed Shares are actually redeemed.

The foregoing summary of the New Non-Redemption Agreement does not purport to be complete and is qualified in its entirety by reference to the form of New Non-Redemption Agreement attached hereto as Exhibit 10.1, which is incorporated herein by reference.

Forward-Looking Statements

This Current Report on Form 8-K includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements may generally be identified by the use of words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect," "should," "would," "plan," "project," "forecast," "seek," "predict," "potential," "target," "outlook" or the negatives of these terms or other similar expressions. These forward-looking statements include, but are not limited to, statements regarding the Company's, the Sponsor's and the Investors' expectations with respect to future performance, anticipated financial impacts, the negotiation, execution and terms of the Non-Redemption Agreements, and the likelihood, timing or effects of the Extension, any initial business combination, or the amount of funds that may remain in the Company's trust account. These statements are based on various assumptions, whether or not identified in this Current Report, and on the current expectations of the Company's management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on 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 the Company. These forward-looking statements are subject to a number of risks and uncertainties, including, among others: the risk that the Non-Redemption Agreements described herein are not entered into on the terms described, or at all; the risk that the Extension is not approved; the amount of redemptions by the Company's public shareholders; the ability of the Company to consummate an initial business combination; and other risks and uncertainties described in the Company's filings with the Securities and Exchange Commission (the "SEC"), including its Annual Report on Form 10-K, its Quarterly Reports on Form 10-Q and its other filings with the SEC. If any of these risks materialize or the Company's assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that the Company presently does not know or that the Company currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect the Company's expectations, plans or forecasts of future events and views as of the date of this Current Report. The Company anticipates that subsequent events and developments will cause the Company's assessments to change. However, while the Company may elect to update these forward-looking statements at some point in the future, the Company specifically disclaims any obligation to do so, except as required by law. These forward-looking statements should not be relied upon as representing the Company's assessments as of any date subsequent to the date of this Current Report. Accordingly, undue reliance should not be placed upon the forward-looking statements.
