Exhibit Number						Description
99.1						Press Release issued by Clear Channel Outdoor Holdings, Inc. on February 26, 2026
104						Cover Page Interactive Data File (formatted as inline XBRL)

Certain statements in this Current Report on Form 8-K, including statements regarding the Merger, stockholder approvals (including the Requisite Stockholder Approval (as defined in the Merger Agreement)), any expected timetable for completing the Merger, the expected benefits of the Merger and any other statements regarding the Company’s future expectations, beliefs, plans, objectives, financial conditions, assumptions or future events or performance that are not historical fact constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the Exchange Act. The words “expect,” “anticipate,” “estimate,” “believe,” “forecast,” “goal,” “intend,” “objective,” “plan,” “project,” “seek,” “strategy,” “target,” “will” and similar words and expressions are intended to identify such forward-looking statements. These forward-looking statements are based on the beliefs and assumptions of management at the time that these statements were prepared and are inherently uncertain. These statements are not guarantees of future performance and are subject to certain risks, uncertainties and other factors, some of which are beyond the Company’s control and are difficult to predict. These risks and uncertainties include, but are not limited to: uncertainties associated with the proposed Merger, including the failure to consummate the Merger in a timely manner or at all, could adversely affect the Company’s business, results of operations, financial condition, and the trading price of the Company’s common stock; the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, including circumstances requiring the Company to pay a termination fee pursuant to the Merger Agreement; failure to satisfy the conditions precedent to consummate the Merger, including the adoption of the Merger Agreement by the affirmative vote (in person or by proxy) of the holders of a majority of the outstanding shares of the Company’s common stock and obtaining required regulatory approvals; the risk that restrictions on the operation of the Company’s business during the pendency of the Merger may impact the Company’s ability to pursue certain business opportunities or strategic transactions or undertake certain actions the Company might otherwise have taken; potential litigation relating to, or other unexpected costs resulting from, the Merger; the risk that any announcements relating to the Merger could have adverse effects on the market price of the Company’s common stock, credit ratings or operating results; and the risk that the Merger and its announcement could have an adverse effect on the ability of the Company to retain and hire key personnel, to retain customers and to maintain relationships with business partners, suppliers and customers. The Company can give no assurance that the conditions to the Merger will be satisfied or that the Merger will close within any anticipated time period. Various risks that could cause future results to differ from those expressed by the forward-looking statements included in this Current Report on Form 8-K are described in the section entitled “Item 1A. Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, initially filed with the SEC on February 26, 2026, as amended by Amendment No. 1 to such Annual Report on Form 10-K/A for the fiscal year ended December 31, 2025, filed with the SEC on March 27, 2026 (the “Annual Report”), as well as other risks and forward-looking statements in other reports and filings with the SEC. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this Current Report on Form 8-K or the date of any document referred to in this Current Report on Form 8-K. Except as required by applicable law, the Company does not undertake any obligation to publicly update or revise any forward-looking statements because of new information, future events or otherwise.
