Q2 2025 Highlights • Total revenues were $9.8 billion, up modestly from the prior year quarter. • Distribution revenues were relatively unchanged, as growth in global streaming subscribers was offset by continued domestic linear pay TV subscriber declines. • Advertising revenues decreased 10% ex-FX(1), as ad-lite streaming subscriber growth was more than offset by domestic linear audience declines. • Content revenues increased 16% ex-FX, primarily driven by higher box office revenues due to the stronger performance of the theatrical releases in the current year quarter. • Net income available to Warner Bros. Discovery, Inc. was $1.6 billion, which includes $1.7 billion of pre-tax acquisition- related amortization of intangibles, content fair value step-up, and restructuring expenses, as well as a $3.0 billion pre- tax gain on the extinguishment of debt. • Total Adjusted EBITDA(2)(*) was $2.0 billion, a 9% ex-FX increase compared to the prior year quarter, primarily due to growth in the Streaming and Studios segments, partially offset by a decline in the Global Linear Networks segment. • Cash provided by operating activities was $1.0 billion. Free cash flow(3)(*) was $0.7 billion. Free cash flow was unfavorably impacted by approximately $250 million of separation-related items. • In conjunction with the announcement of the separation of Streaming & Studios and Global Linear Networks, the Company successfully completed a tender offer and consent solicitation, as well as repaid the $1.5 billion term loan due 2026, financed by a $17.0 billion bridge facility, resulting in a $2.2 billion reduction in gross debt. Additionally, the Company repaid $0.5 billion of debt due in the quarter, resulting in a $2.7 billion total reduction in gross debt during Q2. • The Company ended the quarter with $4.9 billion of cash on hand, $35.6 billion of gross debt(4)(*), and 3.3x net leverage.(5)(*) • The Company ended the quarter with 125.7 million streaming subscribers(6), an increase of 3.4 million subscribers vs. Q1.

Domestic includes the U.S. and Canada. Subscriber counts in the above table are rounded and minor differences in totals may exist. Q2 2025 Highlights • Global streaming subscribers were 125.7 million, an increase of 3.4 million global subscribers vs. Q1. • Streaming revenues increased 8% ex-FX to $2,793 million compared to the prior year quarter. Subscriber-related revenues(8)(*) increased 10% ex-FX compared to the prior year quarter. • Distribution revenue increased 9% ex-FX, as a result of a 22% increase in subscribers following the continued global expansion of HBO Max, as well as new distribution deals, partially offset by an impact from a distribution deal with a former related party and lower global distribution ARPU due to a mix shift in the subscriber base across distribution channels, geography, and product type. • Advertising revenue increased 17% ex-FX, primarily driven by an increase in ad-lite subscribers, partially offset by domestic pricing pressures. • Global streaming ARPU(9) decreased 11% ex-FX to $7.14, primarily attributable to growth in lower ARPU international markets and a 8% decrease in domestic streaming ARPU to $11.16. The decrease in domestic streaming ARPU was primarily driven by broader wholesale distribution of HBO Max Basic with Ads. • Content revenue decreased 21% ex-FX, primarily driven by the launch of HBO Max in new international markets which resulted in lower third-party licensing. • Streaming operating expenses decreased 7% ex-FX to $2,500 million compared to the prior year quarter. • Costs of revenues decreased 6% ex-FX, primarily driven by lower domestic sports costs and the timing of domestic programming releases, partially offset by higher international content costs to support the global expansion of HBO Max. • SG&A decreased 10% ex-FX, largely due to lower marketing costs. • Streaming Adjusted EBITDA was $293 million, a $400 million increase compared to the prior year quarter.

Definitions and Sources for Warner Bros. Discovery, Inc. (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. For the 2025 period, 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 “2025 Baseline Rate”), and the prior year amounts translated at the same 2025 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) third-party transaction and integration costs, (vii) amortization of purchase accounting fair value step-up for content, (viii) amortization of capitalized interest for content, and (ix) other items impacting comparability. The Company uses this measure to assess the operating results and performance of the 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 (which is included in consolidated costs of revenues), and amortization of capitalized interest for content, as these amounts do not represent cash payments in the current reporting period. We prospectively updated certain corporate allocations at the beginning of 2025. The impact to prior periods was immaterial. (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 $35.6 billion as total debt of $35.0 billion, plus finance leases of $584 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 $35.6 billion, less cash, cash equivalents, and restricted cash of $4,891 million) is divided by the sum of the most recent four quarters Adjusted EBITDA of $9,193 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. (6) Streaming Subscriber: The Company defines a “Core Streaming Subscription” as: (i) a retail subscription to discovery+, HBO, HBO Max, Max, or a Premium Sports Product (defined below) for which we have recognized subscription revenue, whether directly or through a third party, from a Streaming platform; (ii) a wholesale subscription to discovery+, HBO, HBO Max, Max, or a Premium Sports Product 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, Max, or a Premium Sports Product for which we have recognized subscription revenue on a per subscriber basis, including third-party services that host a branded environment of discovery+, HBO, HBO Max, Max, or a Premium Sports Product for which we have recognized subscription revenue on a per subscriber basis; (iv) a retail or wholesale subscription to an independently-branded, regional product sold on a stand-alone basis that includes discovery+, HBO, HBO Max, Max, and/or a Premium Sports Product, for which we have recognized subscription revenue (as per (i) – (iii) above); and (v) 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. The Company defines a “Premium Sports Product” as a strategically prioritized, sports-focused product sold on a stand-alone basis and made available directly to consumers. The current “independently-branded, regional products” referred to in (iv) above consist of TVN/Player. Subscribers to multiple WBD Streaming products (listed above) are counted as a paid subscriber for each individual WBD streaming product subscription. We may refer to the aggregate number of Core Streaming Subscriptions as “subscribers”. The reported number of “subscribers” included herein and the definition of “Streaming Subscription” as used herein excludes: (i) individuals who subscribe to Streaming products, other than discovery+, HBO, HBO Max, Max, a Premium Sports Product, and independently-branded, regional products (currently consisting of TVN/Player), 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 Streaming Subscription within the first seven days of the next month as noted above. Domestic subscriber - We define a Domestic subscriber as a subscription based either in the United States of America or Canada. International subscriber - We define an International subscriber as a subscription based outside of the United States of America or Canada. Q2 2025 Earnings Press Release | August 7, 2025 13

Definitions and Sources for Warner Bros. Discovery, Inc. (Continued (7) Streaming & Studios Division: In December 2024, we announced that our board of directors had authorized the Company to implement a new corporate structure designed to enhance our strategic flexibility and create potential opportunities to unlock shareholder value. Under the new corporate structure, the Company will serve as the parent company for two distinct operating divisions: Streaming & Studios and Global Linear Networks. In the first quarter of 2025, we renamed our Direct-to-Consumer reportable segment to Streaming and our Networks reportable segment to Global Linear Networks. There were no changes to our reportable segments or the composition of our reportable segments as a result of these changes. The Streaming & Studios division includes our Streaming and Studios reportable segments and eliminations between those two reportable segments. (8) Subscriber-related revenues: The Company defines subscriber-related revenues as the sum of distribution and advertising revenues in the Streaming segment. The Company uses subscriber-related revenues to monitor and evaluate the Company's streaming revenue performance. The Company believes this measure is relevant to investors as it highlights the revenue generation tied to the Company's streaming products. (9) ARPU: The Company defines Streaming 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) Revenue and subscribers for Streaming products, other than discovery+, HBO, HBO Max, Max, a Premium Sports Product, and independently-branded, regional products (currently consisting of TVN/Player), that may be offered by us or by certain joint venture partners or affiliated parties from time to time; (ii) A limited amount of international discovery+ revenue and subscribers that are part of non-strategic partnerships or short-term arrangements as may be identified by the Company from time to time; (iii) Cinemax, Max/HBO hotel and bulk institution (i.e., subscribers billed on a bulk basis), and international basic HBO revenue and subscribers; 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.
