Warner Bros. Discovery, Inc.

The full register, from 13F filings

The Register tab above is hand research: a dozen holders, each traced to the filing it came from. This asks the same question of the whole market for the quarter ended 31-mar-2026, where 1,287 managers reported a position. Broad where the research is deep, and shallow in the ways a 13F always is.

Built from 13F filings, which report US listed, long, US custodied positions only. A register from this source is a floor rather than a level: a holder's true position can be far larger, as BlackRock's ASML stake shows at 1.28m shares in a 13F against 26.3m in its 13G/A. Holdings held through derivatives, outside US custody, or below a manager's reporting obligation do not appear. Where a holder is marked as a family, its total sums several separate filing entities and describes something no single filing describes; the constituent entities and their share counts are listed so the total can be checked. That roll-up can legitimately exceed the family's own Schedule 13G, because a 13G is filed by one legal entity: Vanguard reports Alphabet through ten advisory entities, and The Vanguard Group Inc itself reported zero after its January 2026 disaggregation.

What a reader needs to know to read these numbers

• Share basis. As of the cover page of the Q2 2026 10-Q (filed 6 Aug 2026), WBD has a single class of common stock outstanding: Series A Common Stock, par value $0.01, 2,510,703,314 shares outstanding as of 23 Jul 2026. Preferred stock is authorized (1,200 shares authorized under the balance sheet caption) but zero shares are issued and outstanding. company.shares_outstanding and every register row's pct_of_company use this single Series A figure; no other class of common or preferred stock currently exists to be excluded. Historically (as Discovery, Inc., pre-April 2022) WBD's predecessor had Series A, B and C common stock with differing voting rights; that structure was collapsed into one class of WBD Series A common stock when Discovery combined with WarnerMedia in April 2022, and no vestige of it remains outstanding today.
• Pending change of control, basis NOT yet affected. WBD terminated its Netflix merger agreement on 27 Feb 2026 (paying Netflix a $2.8 billion termination fee) and entered a merger agreement with Paramount Skydance Corporation (PSKY) the same day, under which PSKY would acquire WBD for $31.00 per share in cash (Larry Ellison and an affiliated trust guaranteed $45.72 billion of the merger consideration). WBD stockholders approved the PSKY merger agreement on 23 Apr 2026. As of the Q2 2026 10-Q (6 Aug 2026), the merger had NOT closed: it is subject to regulatory clearance and other conditions, has an outside date of 4 Mar 2027 (extendable to 4 Jun 2027), and two lawsuits (by a coalition of 12 state attorneys general and two writers' guilds) were pending as of Jul 2026. Because the merger has not closed, this file uses WBD's current, standalone share basis, not any post-merger structure.
• Separation transaction superseded, not completed. WBD had previously planned to split into two public companies (Streaming & Studios, and Global Linear Networks). The PSKY Merger Agreement's terms make PSKY's obligation to close conditional on WBD NOT having completed that separation; per the 10-Q, the separation has not occurred and, if the PSKY merger closes, will not occur as a standalone event. No share count in this file needed restating for a split or separation: none has taken effect.
• Holdings side. The Q2 2026 10-Q and FY2025 10-K equity investments notes (Note on Equity Investments) name three individual equity method investees at 30 Jun 2026 or 31 Dec 2025: The Chernin Group (TCG) 2.0-A, LP (44% ownership, $299m), nC+ (32% ownership, $140m), and TNT Sports (50% ownership, $10m at 31 Dec 2025, no longer broken out separately by 30 Jun 2026). A combined 'Other' equity method bucket ($254m at 30 Jun 2026, covering an unstated number of unnamed investees, and by 30 Jun 2026 apparently including the former TNT Sports balance) and a combined 'Investments without readily determinable fair values' bucket ($313m at 30 Jun 2026) are NOT assigned to any individual holding, per the rule against sizing an unnamed investee from a combined balance; both appear in unknowns instead. Total investments per the 10-Q: $1,006 million at 30 Jun 2026 ($1,045 million at 31 Dec 2025).
• A music-catalog joint venture with Cutting Edge Group (formed Jan 2025, WBD contributed 70% of the catalog interest for $601 million in proceeds, with Cutting Edge receiving an additional 9% economic interest in Q1 2026) is EXCLUDED from holdings: the 10-Q states WBD 'retained a controlling financial interest and consolidated the joint venture as a VIE', so this is a consolidated subsidiary with a third-party noncontrolling interest, not a WBD holding in another company.
• Register self-gate, computed the way the chart computes it: 10 register rows (7 institutional 13F rows, 1 strategic family holder, 2 insider rows), with the officers/directors group counted at its residual beyond Zaslav (5,706,646 = 17,596,032 minus 11,889,386). Summed shares: 955,959,743 against 2,510,703,314 shares outstanding = 38.08%, within the expected 25 to 45 percent band.
• Vanguard Group Inc (CIK 0000102909) filed Form 13F-NT (notice, no holdings) for Q2 2026, confirmed directly (no info table document exists in its filing index), so per the brief's rule the successor entities are summed rather than substituting a single row: Vanguard Capital Management LLC and Vanguard Portfolio Management LLC.
• Capital Group family checked and holds zero WBD shares in Q2 2026: Capital World Investors (CIK 0001422849), Capital International Investors (CIK 0001562230) and Capital Research Global Investors (CIK 0001422848) were each searched by both 'WARNER' and 'WARNER BROS' name fragments across their full Q2 2026 13F-HR info tables; none returned CUSIP 934423104. No Capital Group row appears in the register as a result.
• T. Rowe Price Investment Management, Inc. (CIK 0001897612) also holds zero WBD shares in Q2 2026, checked the same way; only T. Rowe Price Associates, Inc. (CIK 0000080255) holds a position, and its 13F reports the value in thousands (see the T. Rowe Price row's method_note).
• Unresolved discrepancy: the Advance/Newhouse family's most recent Schedule 13D/A (2 Apr 2024, 198,181,749 shares, 8.12% of class as then stated) is not reflected at all in WBD's 2026 DEF 14A beneficial-ownership-of-5%-owners table, which lists only BlackRock, State Street and a stale Vanguard Schedule 13G (Oct 2025 amendment). Neither WBD's own SC 13 filing history nor Advance/Newhouse Programming Partnership's own EDGAR submissions feed shows any newer 13D/A, 13G or Form 4 disaggregating or reducing this position, so it is included here as the best available sourced figure with an explicit staleness caveat rather than omitted or silently treated as current.
• Market capitalization ($70.12 billion) and share price ($27.93) are from stockanalysis.com as of the 17 Aug 2026 close. Cross-check: 2,510,703,314 shares x $27.93 implies approximately $70.13 billion, consistent with the reported market cap. WBD's share price has risen sharply since 2025 on the pending PSKY acquisition at $31.00/share cash.
