PART I

CAUTIONARY NOTE CONCERNING FORWARD-LOOKING STATEMENTS

Certain statements in this Annual Report on Form 10-K constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding our business, marketing and operating strategies, integration of acquired businesses, new product and service offerings, financial prospects and anticipated sources and uses of capital. Words such as “anticipate,” “assume,” “believe,” “continue,” “estimate,” “expect,” “forecast,” “future,” “intend,” “plan,” “potential,” “predict,” “project,” “strategy,” “target” and similar terms, and future or conditional tense verbs like “could,” “may,” “might,” “should,” “will” and “would,” among other terms of similar substance used in connection with any discussion of future operating or financial performance identify forward-looking statements. Where, in any forward-looking statement, we express an expectation or belief as to future results or events, such expectation or belief is expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the expectation or belief will result or be accomplished. The following is a list of some, but not all, of the factors that could cause actual results or events to differ materially from those anticipated:

• more intense competitive pressure from existing or new competitors in the industries in which we operate;

• reduced spending on domestic and foreign television advertising, due to macroeconomic, industry or consumer behavior trends or unexpected reductions in our number of subscribers;

• uncertainties associated with product and service development and market acceptance, including the development and provision of programming for new television and telecommunications technologies, and the success of our streaming services;

• market demand for foreign first-run and existing content libraries;

• negative publicity or damage to our brands, reputation or talent;

• realizing direct-to-consumer subscriber goals;

• industry trends, including the timing of, and spending on, sports programming, feature film, television and television commercial production;

• the possibility or duration of an industry-wide strike, such as the strikes of the Writers Guild of America (“WGA”) and Screen Actors Guild-American Federation of Television and Radio Artists (“SAG-AFTRA”) in 2023, player lock-outs or other job action affecting a major entertainment industry union, athletes or others involved in the development and production of our sports programming, television programming, feature films and interactive entertainment (e.g., games) who are covered by collective bargaining agreements;

• disagreements with our distributors or other business partners;

• continued consolidation of distribution customers and production studios;

• potential unknown liabilities, adverse consequences or unforeseen increased expenses associated with the WarnerMedia Business or our efforts to integrate the WarnerMedia Business;

• adverse outcomes of legal proceedings or disputes related to our acquisition of the WarnerMedia Business;

• changes in, or failure or inability to comply with, laws and government regulations, including, without limitation, regulations of the Federal Communications Commission and similar authorities internationally and data privacy regulations, and adverse outcomes from regulatory or legal proceedings;

• inherent uncertainties involved in the estimates and assumptions used in the preparation of financial forecasts;

• our level of debt, including the significant indebtedness incurred in connection with the acquisition of the WarnerMedia Business, and our future compliance with debt covenants;

• threatened or actual cyber-attacks and cybersecurity breaches;

• theft of our content and unauthorized duplication, distribution and exhibition of such content; and

• general economic and business conditions, fluctuations in foreign currency exchange rates, global events such as pandemics, and political unrest in the international markets in which we operate.

Forward-looking statements are subject to various risks and uncertainties which change over time, are based on management’s expectations and assumptions at the time the statements are made and are not guarantees of future results.

These risks have the potential to impact the recoverability of the assets recorded on our balance sheets, including goodwill or other intangibles. Management’s expectations and assumptions, and the continued validity of any forward-looking statements we make, cannot be foreseen with certainty and are subject to change due to a broad range of factors affecting the U.S. and global economies and regulatory environments, factors specific to Warner Bros. Discovery and other factors described under Item 1A, “Risk Factors” and elsewhere in this Annual Report on Form 10-K, including under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Actual outcomes and results may differ materially from what is expressed in our forward-looking statements and from our historical financial results due to the factors discussed in this section and elsewhere in this Annual Report on Form 10-K or disclosed in our other SEC filings. These forward-looking statements and such risks, uncertainties, and other factors speak only as of the date of this Annual Report on Form 10-K, and we expressly disclaim any obligation or undertaking to disseminate any updates or revisions to any forward-looking statement contained herein, to reflect any change in our expectations with regard thereto, or any other change in events, conditions or circumstances on which any such statement is based.
