Revenues decreased 4% ex-FX(1)(*), compared to the prior year quarter, on a combined basis(2). • Net loss available to Warner Bros. Discovery, Inc. was $(1,240) million, and included $1,658 million of pre-tax amortization from acquisition-related intangible assets and $146 million of pre-tax restructuring expenses. • Q2 total Adjusted EBITDA(3)(*) was $2,149 million. Adjusted EBITDA increased 23% ex-FX compared to the prior year quarter, on a combined basis. • Cash provided by operating activities increased to $2,014 million. Reported free cash flow(4)(*) increased to $1,722 million. • Q2 2023 cash provided by operating activities and reported free cash flow are not directly comparable to the prior year quarter due to the acquisition of the WarnerMedia business. • Repaid $1.6 billion of debt during Q2.

The important work we are doing to transform our businesses for the future continues to drive our strong financial performance as demonstrated by meaningful improvements to our balance sheet and our now increased synergy target of more than $5 billion. This quarter alone we reported over $1.7 billion in free cash flow, and we remain bullish with respect to our delevering story and expect to be comfortably below 4.0x levered by the end of the year and at our target of 2.5-3.0x gross leverage by the close of 2024. All of which positions us well to lean into growth opportunities that will ultimately drive shareholder value, to include our Direct-to-Consumer business, which, in the wake of the successful launch of Max in the U.S., is tracking well ahead of our financial projections, having generated positive EBITDA in the first half of the year. – David Zaslav, President & CEO

• Networks revenues were $5,758 million. Revenues decreased 5% ex-FX, compared to the prior year quarter, on a pro forma combined basis. • Distribution revenue decreased 1% ex-FX, primarily driven by increases in U.S. contractual affiliate rates, which were more than offset by declines in U.S. pay-TV subscribers. • Advertising revenue decreased 13% ex-FX, primarily driven by audience declines in domestic general entertainment and news networks and soft advertising markets mainly in the U.S. and, to a lesser extent, certain international markets. Additionally, the absence of the NCAA March Madness Final Four and Championship this year, which we broadcast in the prior year, negatively impacted the year-over- year growth rate, partially offset by the broadcast of the NHL Stanley Cup Finals in the current year. • Content revenue increased 18% ex-FX, primarily driven by the timing of inter-segment content licensing to DTC. • Other revenue increased 24% ex-FX, primarily due to services provided to the unconsolidated TNT Sports JV (previously BT Sport). • Networks operating expenses were $3,592 million. Operating expenses decreased 4% ex-FX compared to the prior year quarter, on a pro forma combined basis. • Costs of revenues decreased 5% ex-FX, primarily driven by the broadcast of the NCAA March Madness Final Four and Championship in the prior year, lower domestic general entertainment content expense.

(*) A non-GAAP financial measure; see the section starting on page 12 titled Definitions & Sources for additional details Q2 2023 Earnings Press Release | August 3, 2023

12 Definitions and Sources for Warner Bros. Discovery, Inc. (1) Foreign Exchange Impacting Comparability: In addition to the Merger (as defined below), 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 “Baseline Rate”), and the prior year amounts translated at the 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) Pro Forma Combined Financial Information: The unaudited pro forma combined financial information in this press release presents the combined results of the Company and the WarnerMedia business as if the transaction whereby the Company acquired the WarnerMedia business (the "Merger") had been completed on January 1, 2021. Management believes reviewing our actual operating results in addition to pro forma combined results is useful in identifying trends in, or reaching conclusions regarding, the overall operating performance of our businesses. Our Networks, DTC, Studios, Corporate, and Inter-segment eliminations pro forma combined financial information is based on the historical operating results and includes adjustments in accordance with Article 11 of Regulation S-X to illustrate the effects of the Merger as if it had occurred on January 1, 2021. The unaudited pro forma financial information is presented for informational purposes and is not indicative of the results of operations that would have been achieved if the Merger had occurred on January 1, 2021, nor is it indicative of future results. The unaudited pro forma combined financial information includes, where applicable, adjustments for (i) additional costs of revenues from the fair value step-up of film and television library, (ii) additional amortization expense related to acquired intangible assets, (iii) additional depreciation expense from the fair value of property and equipment, (iv) transaction costs and other one-time non-recurring costs, (v) additional interest expense for borrowings related to the Merger and amortization associated with fair value adjustments of debt assumed, (vi) changes to align accounting policies, (vii) elimination of intercompany activity, and (viii) associated tax-related impacts of adjustments. These pro forma adjustments are based on available information as of the date hereof and upon assumptions that the Company believes are reasonable to reflect the impact of the Merger with the WarnerMedia business on the Company's historical financial information on a supplemental pro forma basis. Adjustments do not include costs related to integration activities, cost savings or synergies that have been or may be achieved by the combined business. We may refer to total company results (ex. Revenues, Adj. EBITDA) as "combined basis". For historical pro forma financial information including segment level detail and reconciliations of non-GAAP metrics to their GAAP equivalent, 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). (3) 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. (4) 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. (5) Gross debt: The Company defines gross debt of $47.8 billion as total debt of $47.6 billion, plus finance leases of $246 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. Q2 2023 Earnings Press Release | August 3, 2023

(6) Net leverage: The Company defines net leverage as the calculation where net debt (gross debt of $47.8 billion, less cash, cash equivalents, and restricted cash of $3.1 billion) is divided by the sum of the most recent four quarters Adjusted EBITDA of $9,787 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. (7) Direct-to-Consumer ("DTC") Subscriber: The Company defines a “DTC Subscription” as: (i) a retail subscription to discovery+, HBO, HBO Max, or Max for which we have recognized subscription revenue, whether directly or through a third party, from a direct-to-consumer platform; (ii) a wholesale subscription to discovery+, HBO, HBO Max, or Max for which we have recognized subscription revenue from a fixed-fee arrangement with a third party and where the individual user has activated their subscription; (iii) a wholesale subscription to discovery+, HBO, HBO Max, or Max for which we have recognized subscription revenue on a per subscriber basis; and (iv) users on free trials who convert to a subscription for which we have recognized subscription revenue within the first seven days of the calendar month immediately following the month in which their free trial expires. 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. (8) Source: 75th Emmy awards nomination list (https://www.emmys.com/downloads). 181 nominations include an overlapping nomination between Warner Bros. Television Group and Adult Swim. (9) ARPU: The Company defines DTC Average Revenue Per User ("ARPU") as total subscription revenue plus net advertising revenue for the period divided by the daily-average number of paying subscribers for the period. Where daily values are not available, the sum of beginning of period and end of period divided by two is used. Excluded from the ARPU calculation are: (i) Max/HBO Hotel and Bulk Institution subscription revenue and subscribers (i.e., subscribers billed on a bulk basis); (ii) Cinemax subscription revenue and subscribers; (iii) HBO Basic subscription revenue and subscribers (International-only); (iv) Non-discovery+ DTC revenue and subscribers; and (v) Non-Core discovery+ revenue and subscribers, and (vi) users on free trials who convert to a subscription for which we have recognized subscription revenue within the first seven days of the calendar month. (10) 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.
