Explanatory Note

On July 25, 2023, BlueRiver Acquisition Corp. (the “Company”) and BlueRiver Ventures, LLC (the “Sponsor”), the sponsor of the Company, entered into a non-redemption agreement (“Non-Redemption Agreement”) with one or more unaffiliated third party or parties in exchange for such third party or third parties agreeing not to redeem an aggregate of 200,000 shares of the Company sold in its initial public offering (“Non-Redeemed Shares”) at the special meeting called by the Company (the “Special Meeting”) to approve an extension of time for the Company to consummate an initial business combination (the “Extension Proposal”) from August 2, 2023 to February 2, 2024 (the “Extension”). In exchange for the foregoing commitments not to redeem such shares, the Sponsor has agreed to transfer to such third party or third parties an aggregate of 40,000 shares of the Company held by the Sponsor immediately following consummation of an initial business combination if they continue to hold such Non-Redeemed Shares through the Special Meeting. The Non-Redemption Agreements are not expected to increase the likelihood that the Extension Proposal is approved by Company shareholders but will increase the amount of funds that remain in the Company’s trust account following the Special Meeting. The foregoing summary of the Non-Redemption Agreement does not purport to be complete and is qualified in its entirety by reference to the form of Non-Redemption Agreement filed herein as Exhibit 10.1 and incorporated herein by reference.
