Net of taxes and subject to certain adjustments as described in WBD’s definitive proxy statement filed with the SEC on February 17, 2026. Illustratively, in a hypothetical scenario in which no debt is allocated to Discovery Global - which is highly unlikely to occur and is inconsistent with the WBD Board’s intent and expectation that the net debt of WBD will be allocated between WBD and Discovery Global in a way that maximizes the Netflix merger consideration and that is in the best interests of WBD’s shareholders - the Netflix merger agreement technically permits a maximum net debt reduction at Discovery Global that would resuit in a minimum merger consideration of $21.23 per WBD share. 2. Midpoints of the selected public companies analysis on a whole company basis and sum-of-the-parts basis that the Board viewed as particularly relevant in evaluating the value of Discovery Global in the context of the separation. The value of Discovery Global is uncertain. See WBD’s definitive proxy statement for more information. 3. Unaffected stock price defined as closing price on 9/10/25. 4. As of February 13, 2026. 5.

WARNER BROS. DISCOVERY This communication has been sent to everyone at WBD. Team, Today we are sharing an important update on our transaction. You can read our press release here. We have announced that the Special Meeting of Shareholders to vote on the proposed Netflix merger will take place on March 20, 2026 at 8:00 a.m. Eastern Time. The Board continues to recommend that shareholders vote FOR the Netflix merger. With the announcement of the Special Meeting date, voting is now open and will continue through 11:59 p.m. EST on March 19. Employees who were shareholders as of the record date (February 4, 2026) will receive information about how to participate, and I encourage you to review the materials carefully. You can visit our website to learn how to vote: VoteWBDNetflix.com. While preparation for the shareholder vote on the Netflix merger continues, we will spend the next seven days engaging with Paramount Skydance to

discuss its amended offer as part of the thorough and disciplined process we have been running from the start. Paramount Skydance has recently indicated it may improve its proposal from $30 per WBD share. We are using this seven-day window to quickly determine whether PSKY can deliver an actionable binding proposal that provides superior value, transaction certainty and downside protection to WBD shareholders. Preparing for the shareholder vote for the Netflix merger while simultaneously initiating this engagement with Paramount Skydance allows the shareholder vote timeline for the Netflix merger to move forward while ensuring the Board continues to fulfill its responsibilities to evaluate proposals appropriately. Throughout this process, our Board’s focus has been to secure the best possible outcome while protecting the long-term strength of our businesses, our brands, and our people. That remains unchanged. I know these last months have asked a great deal of you. You continue to deliver for our audiences while supporting one another through significant change, and I am grateful for the professionalism and commitment you bring every day. We will continue to communicate as this work progresses, and when there is news that directly affects our people, you will continue to hear it from us. Thank you for everything you do for the audiences we serve around the world. David

Forward-Looking Statements

Information set forth in this communication, including financial estimates and statements as to the expected timing, completion and effects of the proposed transaction between WBD and Netflix, constitute forward-looking statements. These estimates and statements are subject to risks and uncertainties, and actual results might differ materially. Such estimates and statements include, but are not limited to, statements about the benefits of the proposed transaction, including future financial and operating results, the combined company’s plans, objectives, expectations and intentions, statements about the tender offer and other statements that are not historical facts. Such statements are based upon the current beliefs and expectations of the management of WBD and Netflix and are subject to significant risks and uncertainties outside of our control.

Among the risks and uncertainties that could cause actual results to differ from those described in the forward-looking statements are the following: (1) the completion of the proposed transaction may not occur on the anticipated terms and timing or at all; (2) the occurrence of any event, change or other circumstances that could give rise to the termination of the proposed transaction; (3) the risk that WBD stockholders may not approve the proposed transaction; (4) the risk that the necessary regulatory approvals for the proposed transaction may not be obtained or may be obtained subject to conditions that are not anticipated; (5) risks that any of the closing conditions to the proposed transaction may not be satisfied in a timely manner; (6) the final allocation of indebtedness between WBD and a newly formed subsidiary (“Discovery Global”) in connection with the separation could cause a reduction to the consideration for the proposed transaction; (7) risks related to litigation brought in connection with the proposed transaction; (8) risks related to disruption of management time from ongoing business operations due to the proposed transaction; (9) effects of the announcement, pendency or completion of the proposed transaction on the ability of WBD to retain customers and retain and hire key personnel and maintain relationships with suppliers, distributors, advertisers, content providers, vendors and other business partners, and on its operating results and business generally; (10) negative effects of the announcement or the consummation of the proposed transaction on the market price of WBD common stock; (11) risks related to the potential impact of general economic, political and market factors on the companies or the proposed transaction; (12) inherent uncertainties involved in the estimates and assumptions used in the preparation of financial projections, and inherent uncertainties involved in the estimates and judgments used to estimate the differences between WBD’s Global Linear Networks segment results and the expected results of Discovery Global; (13) the risk that Discovery Global, as a new company that currently has no credit rating, will not have access to the capital markets on acceptable terms; (14) the risk that Discovery Global may be unable to achieve some or all of the benefits that WBD expects Discovery Global to achieve as an independent, publicly-traded company; (15) the risk that Discovery Global may be more susceptible to market fluctuations and

other adverse events than it would have otherwise been while still a part of WBD; (16) the risk that Discovery Global will incur significant indebtedness in connection with the separation, and the degree to which it will be leveraged following completion of the separation may materially and adversely affect its business, financial condition and results of operations; (17) the ability to obtain or consummate financing or refinancing related to the proposed transaction or the separation upon acceptable terms or at all; (18) volatility or a decline in the market price for Discovery Global common stock following the separation; (19) uncertainties as to how many WBD stockholders will tender their shares in the tender offer; (20) the conditions to the completion of the tender offer, including the receipt of any required stockholder and regulatory approvals; (21) PSKY’s ability to finance the tender offer and the indebtedness PSKY expects to incur in connection with the tender offer; (22) the possibility that PSKY may be unable to achieve expected synergies and operating efficiencies within the expected timeframes or at all and to successfully integrate WBD’s operations with those of PSKY, and the possibility that such integration may be more difficult, time-consuming or costly than expected or that operating costs and business disruption (including, without limitation, disruptions in relationships with employees, customers or suppliers) may be greater than expected in connection with the tender offer; (23) the possibility that WBD’s discussions with PSKY may not lead to a superior proposal by PSKY; and (24) the response of WBD, Netflix or PSKY management to any of the aforementioned factors.
