I am very pleased with the strong financial results that our company delivered in Q3, underscored by 22% growth in Adjusted EBITDA and over $2 billion in free cash flow, putting us on track to meaningfully exceed $5 billion for the year and contributing to our nearly $12 billion in debt paydown to date. Among the highlights, our Direct-to-Consumer business had another profitable quarter with $111 million of Adjusted EBITDA and launched its new live-programming offerings with CNN Max and the Bleacher Report Add- On, which are showing early signs of contributing to increased engagement and lower churn on Max. We’ve made great strides in just 19 months and are excited to continue building on this strong momentum, as we focus on driving future growth and creating long-term value for our shareholders. – David Zaslav, President & CEO

• Studios revenues were $3,226 million. Revenues increased 3% ex-FX compared to the prior year quarter. • Content revenue increased 3% ex-FX. • Theatrical revenue increased significantly due to the strong performance of Barbie as well as more titles released in the current year quarter. • Games revenue increased meaningfully due to the Q3 release of Mortal Kombat 1 and continued performance of Hogwarts Legacy. • TV revenue declined significantly primarily due to certain large licensing deals in the prior year and the impact of the WGA and SAG-AFTRA strikes. • Other revenue increased 5% ex-FX, due to the Q2 opening of Warner Bros. Studio Tour Tokyo and continued strong attendance at Warner Bros. Studio Tours London & Hollywood, partially offset by the impact of the WGA and SAG-AFTRA strikes on studio production services. • Studios operating expenses were $2,499 million. Operating expenses increased 6% ex-FX compared to the prior year quarter. • Costs of revenues increased 1% ex-FX, primarily driven by higher theatrical and games content expense commensurate with higher revenues, partially offset by lower TV content expense, including strike-related impacts. • SG&A expenses increased 21% ex-FX, primarily driven by higher theatrical marketing expense due to the increased release slate. • Studios Adjusted EBITDA was $727 million.

(1) Foreign Exchange Impacting Comparability: The impact of exchange rates on our business is an important factor in understanding period-to-period comparisons of our results. For example, our international revenues are favorably impacted as the U.S. dollar weakens relative to other foreign currencies, and unfavorably impacted as the U.S. dollar strengthens relative to other foreign currencies. We believe the presentation of results on a constant currency basis ("ex-FX"), in addition to results reported in accordance with U.S. GAAP provides useful information about our operating performance because the presentation ex-FX excludes the effects of foreign currency volatility and highlights our core operating results. The presentation of results on a constant currency basis should be considered in addition to, but not a substitute for, measures of financial performance reported in accordance with U.S. GAAP. The ex-FX change represents the percentage change on a period-over-period basis adjusted for foreign currency impacts. The ex-FX change is calculated as the difference between the current year amounts translated at a baseline rate, which is a spot rate for each of our currencies determined early in the fiscal year as part of our forecasting process (the “2023 Baseline Rate”), and the prior year amounts translated at the same 2023 Baseline Rate. In addition, consistent with the assumption of a constant currency environment, our ex-FX results exclude the impact of our foreign currency hedging activities, as well as realized and unrealized foreign currency transaction gains and losses. Results on a constant currency basis, as we present them, may not be comparable to similarly titled measures used by other companies. (2) Adjusted EBITDA: The Company evaluates the operating performance of its operating segments based on financial measures such as revenues and Adjusted EBITDA. Adjusted EBITDA is defined as operating income excluding: (i) employee share-based compensation, (ii) depreciation and amortization, (iii) restructuring and facility consolidation, (iv) certain impairment charges, (v) gains and losses on business and asset dispositions, (vi) certain inter-segment eliminations, (vii) third-party transaction and integration costs, (viii) amortization of purchase accounting fair value step-up for content, (ix) amortization of capitalized interest for content, and (x) other items impacting comparability. The Company uses this measure to assess the operating results and performance of its segments, perform analytical comparisons, identify strategies to improve performance, and allocate resources to each segment. The Company believes Adjusted EBITDA is relevant to investors because it allows them to analyze the operating performance of each segment using the same metric management uses. The Company excludes employee share-based compensation, restructuring, certain impairment charges, gains and losses on business and asset dispositions, and transaction and integration costs from the calculation of Adjusted EBITDA due to their impact on comparability between periods. Integration costs include transformative system implementations and integrations, such as Enterprise Resource Planning systems, and may take several years to complete. The Company also excludes the depreciation of fixed assets and amortization of intangible assets, amortization of purchase accounting fair value step-up for content, and amortization of capitalized interest for content, as these amounts do not represent cash payments in the current reporting period. Certain corporate expenses and inter-segment eliminations related to production studios are excluded from segment results to enable executive management to evaluate segment performance based upon the decisions of segment executives. Adjusted EBITDA should be considered in addition to, but not a substitute for, operating income, net income, and other measures of financial performance reported in accordance with U.S. GAAP. (3) Free cash flow: The Company defines free cash flow as cash flow from operations less acquisitions of property and equipment. The Company believes free cash flow is an important indicator for management and investors of the Company’s liquidity, including its ability to reduce debt, make strategic investments, and return capital to stockholders. (4) Gross debt: The Company defines gross debt of $45.3 billion as total debt of $45.1 billion, plus finance leases of $258 million. The Company believes this measure is relevant to investors as it is a financial measure frequently used in evaluating a company's financial condition. (5) Net leverage: The Company defines net leverage as the calculation where net debt (gross debt of $45.3 billion, less cash, cash equivalents, and restricted cash of $2.4 billion) is divided by the sum of the most recent four quarters Adjusted EBITDA of $10,332 million. The Company believes this measure is relevant to investors as it is a financial measure frequently used in evaluating a company's financial condition. Please refer to the Trending Schedules and Non-GAAP Reconciliations posted in the "Quarterly Results" section of the Company's investor relations website (https://ir.wbd.com) for the full reconciliation of net leverage.

We may refer to the aggregate number of DTC Subscriptions as “subscribers". We define a Domestic subscriber as a subscription based either in the United States of America or Canada. We define an International subscriber as a subscription based outside of the United States of America or Canada. The reported number of “subscribers” included herein and the definition of “DTC Subscription” as used herein excludes: (i) individuals who subscribe to DTC products, other than discovery+, HBO, HBO Max, and Max, that may be offered by us or by certain joint venture partners or affiliated parties from time to time; (ii) a limited number of international discovery+ subscribers that are part of non-strategic partnerships or short-term arrangements as may be identified by the Company from time to time; (iii) domestic and international Cinemax subscribers, and international basic HBO subscribers; and (iv) users on free trials except for those users on free trial that convert to a DTC Subscription within the first seven days of the next month as noted above. 12 Definitions and Sources for Warner Bros.

(11) 2023 outlook: Warner Bros. Discovery is not able to provide a reconciliation of the non-GAAP forward-looking commentary to comparable GAAP measures as, at this time, the Company cannot determine the occurrence or impact of the adjustments, such as the effect of future changes in foreign currency exchange rates or future acquisitions or divestitures that would be excluded from such GAAP measures. Accordingly, the Company is relying on the exception provided by Item 10(e)(1)(i)(B) of Regulation S-K to exclude these reconciliations. Source: Warner Bros. Discovery, Inc.
