Failure to Satisfy Listing Rule Form 8 K

As previously disclosed, on September 3, 2024, Concord Acquisition Corp II (the "Company") received a letter from the NYSE American LLC ("NYSE American" or the "Exchange") stating that the staff of NYSE Regulation (the "Staff") has determined to commence proceedings to delist the Company's Class A Common Stock, Units and Warrants (collectively, the "Securities") pursuant to Sections 119(b) and 119(f) of the NYSE American Company Guide because the Company failed to consummate a business combination within 36 months of the effectiveness of its initial public offering registration statement, or such shorter period that the Company specified in its registration statement. As indicated in the letter, the Company has a right to a review of the delisting determination by the Listings Qualifications Panel of the Committee for Review of the Board of Directors of the Exchange (the "Panel").

The Company timely requested a hearing before the Panel to request sufficient time to complete a business combination, which was held on November 7, 2024. The Panel's hearing considered written and oral presentations made by the Company and the Staff. On November 13, 2024, the Panel issued written notice of its decision stating that the Panel upholds the Staff's determination to initiate delisting proceedings. The Company may request that the full Committee for Review of NYSE American (the "Committee for Review") reconsider the decision of the Panel. The Company does not intend to have the full Committee for Review reconsider the decision of the Panel. NYSE American will complete the delisting by filing a Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities and Exchange Act of 1934, as amended (the "Exchange Act"), on Form 25 with the U.S. Securities and Exchange Commission.
