(*) A non-GAAP financial measure; see the section starting on page 13 titled Definitions & Sources for additional details Q4 and Full-Year 2022 Earnings Press Release | February 23, 2023

13 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 “2022 Baseline Rate”), and the prior year amounts translated at the same 2022 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 combined Networks, DTC, Studios, Corporate, and inter-segment eliminations pro forma combined financial information is based on the historical operating results of the respective segments 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. 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. Q4 and Full-Year 2022 Earnings Press Release | February 23, 2023

(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 $49.5 billion as total debt of $49.3 billion, plus finance leases of $268 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) Net leverage: The Company defines net leverage as the calculation where net debt (gross debt of $49.5 billion, less cash, cash equivalents, and restricted cash of $1.0 billion) is divided by the sum of the most recent four quarters Adjusted EBITDA of $9,174 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 or HBO 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, or HBO 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 or HBO 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 and HBO 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) 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) HBO 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. (13) 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.
