Concord Acquisition Corp III Receives Noncompliance Notification from the New York Stock Exchange Regarding Minimum Public Stockholders

Concord Acquisition Corp III (the "Company") announced it had received a notification dated January 19, 2024 (the "Notice") from the New York Stock Exchange (the "NYSE") informing the Company that, because the number of public stockholders is less than 300, the Company is not in compliance with Section 802.01B of the NYSE Listed Company Manual (the "Listing Rule"). The Listing Rule requires the Company to maintain a minimum of 300 public stockholders on a continuous basis. The Notice specifies that the Company has 45 days to submit a business plan that demonstrates how the Company expects to return to compliance with the Listing Rule within 18 months of receipt of the Notice.

The Company plans to promptly submit a business plan that demonstrates how the Company expects to return to compliance with the Listing Rule within 18 months of receipt of the Notice.

The Notice has no immediate impact on the Company's common stock, and provided the NYSE approves the plan, the Company's common stock will continue to be listed and traded on the NYSE during the 18-month period, subject to the Company's compliance with other NYSE listing standards and periodic review by the NYSE of the Company's progress under the plan.
