Amendment to Annual Report (Form 10-K/A)

This Amendment No. 1 to the Annual Report on Form 10-K (the "Form 10-K/A") of Clear Channel Outdoor Holdings, Inc. for the year ended December 31, 2025, filed with the Securities and Exchange Commission (the "SEC") on February 26, 2026 (the "Original Form 10-K"), is being filed solely for the purpose of including the information required by Part III of Form 10-K that the Company did not include in the Original Form 10-K in reliance on General Instruction G(3) to Form 10-K. We are filing this Form 10-K/A to include Part III information in our Form 10-K because we do not intend to file a definitive proxy statement for an annual meeting of stockholders containing such information within 120 days after December 31, 2025.

In addition, in connection with the filing of this Form 10-K/A and pursuant to the rules of the SEC, we are including with this Form 10-K/A new certifications of our principal executive officer and principal financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Item 15 of Part IV has also been amended to reflect the filing of these new certifications.

Except as described above, this Form 10-K/A does not modify or update the disclosures in, or any exhibits to, the Original Form 10-K. Furthermore, this Form 10-K/A does not change any previously reported financial results, nor does it reflect any events which occurred subsequent to the filing of the Original Form 10-K. Information not affected by this Form 10-K/A remains unchanged and reflects the disclosures made at the time the Original Form 10-K was filed.

Unless otherwise specified or indicated by the context, "Clear Channel Outdoor," the "Company," "we," "us" and "our" refer to Clear Channel Outdoor Holdings, Inc. and its consolidated subsidiaries.
