Crown Castle 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 940 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

• The fiber sale (the 'Strategic Fiber Transaction', signed 13 Mar 2025) CLOSED on 1 May 2026: Zayo Group Holdings Inc. acquired the fiber solutions business and EQT Active Core Infrastructure fund acquired the small cells business. Source: Q2 2026 10-Q (filed 5 Aug 2026), note 3 and MD&A. Crown Castle received aggregate net cash proceeds of $8.4 billion (gross contractual purchase price $8.5 billion less $124 million of preliminary purchase-price adjustments, subject to post-closing settlement). The transaction is presented as discontinued operations, with the divested assets/liabilities dropping to zero on the June 30, 2026 balance sheet (versus $10.7bn of assets and $2.3bn of liabilities classified as held-for-sale at Dec 31, 2025).
• Crown Castle did NOT retain any equity interest in the divested Fiber Business, and did not receive equity in Zayo or EQT: this was an all-cash divestiture. Searched the Q2 2026 10-Q for 'equity method', 'unconsolidated', 'non-marketable', 'joint venture', 'retained interest' and 'equity interest': none of these terms appear anywhere in the filing except two unrelated hits for 'equity interests' in the debt-collateral description (pledges securing Crown Castle's own borrowing subsidiaries, unrelated to the fiber sale). Also searched the FY2025 10-K (filed 23 Feb 2026, describing the then-pending sale) for the same terms plus 'rollover equity', 'minority stake' and 'retain an equity': no hits describing any retained stake. Also checked Exhibit 21 (subsidiaries list) of the FY2025 10-K: it is a bare name list with no ownership-percentage column and no reference to the divested fiber entities (consistent with a clean, complete divestiture), so it offered no further evidence either way but confirms the exhibit format itself carries no percentage data here. Given this, the holdings array is intentionally empty: this is a genuine, sourced full exit with nothing to size, not a gap. No other equity-method investments, joint ventures or non-marketable securities of any kind (fiber-related or otherwise) were found in either filing.
• Register self-gate, computed from this final file exactly as the chart computes it (no rows carry rolls_up_into or is_aggregate, so every row counts at full value): 11 rows, 238,850,294 shares total, 56.14% of shares_outstanding (425,455,439 at 3 Aug 2026). This is modestly above the 15-55% band flagged in the research brief as a signal to double check. The cause traced and confirmed rather than a bug: effective 1 May 2026 (immediately after the fiber sale closed), Crown Castle's board authorized a $1.0 billion '2026 Stock Repurchase Program' funded by the sale proceeds; the Company completed the full $1.0 billion buyback (approximately 11 million shares) during Q2 2026 (Q2 2026 10-Q, note 10). That buyback, plus continued institutional accumulation, shrank the share base that these unchanged or growing institutional share counts are now a percentage of: shares outstanding fell from 436,451,983 at 5 May 2026 to 425,455,439 at 3 Aug 2026, a reduction of 10,996,544, which matches the approximately 11 million shares repurchased. (Corrected 19 Aug 2026 by the coordinator: this sentence previously read 'from roughly 484 million (implied by 10-K era weighted-average figures)', which was wrong and contradicted the 11 million figure in the same sentence. The cover-page series was re-fetched from XBRL dei:EntityCommonStockSharesOutstanding: 435,479,010 at 4 Nov 2025, 436,070,436 at 19 Feb 2026, 436,451,983 at 5 May 2026, 425,455,439 at 3 Aug 2026.) A BASIS POINT that matters for reading the 56.14%: every holder count here is measured at 30 Jun 2026, which is BEFORE the denominator's 3 Aug 2026 date, so the counts sit against a post-buyback share base. On the 5 May 2026 count of 436,451,983, which brackets the other side of the 13F measurement date, the same 238,850,294 shares are 54.73%, inside the brief's band. The newest cover page is used because that is this project's convention, and the two readings differ by 1.41 percentage points, so no conclusion drawn from this file changes between them. Corroborated independently by the coordinator against this project's own 13F-derived register (data/registers/CCI.json, period 31 Mar 2026, separate pipeline): total institutional there is 347,247,498 shares, 81.62% of the same denominator, and its top eleven holders alone sum to 254,812,012 shares, 59.89%, so the 56.14% recorded here is if anything conservative rather than inflated, which mechanically raises every holder's ownership percentage versus the DEF 14A's stale 13G-based table (Vanguard 15.78%, BlackRock 8.90%, Cohen & Steers 8.33%, State Street 5.10%, all as of dates in 2025, before the buyback). All implied per-share prices across all 11 filers cluster tightly at $75.5-$75.75, which is the cross-filer consistency check the chunk-12/19-27 notes call for and found no further anomalies beyond the two thousands-unit corrections already documented in Cohen & Steers' and T. Rowe Price Associates' rows.
• Prior-year (stale) 13G figures from the DEF 14A (filed 6 Apr 2026, table 'as of March 23, 2026' with underlying 13G/A dates ranging Mar-Nov 2025) for cross-reference only, not used in the register rows: The Vanguard Group 68,840,472 sh (15.78%), BlackRock, Inc. 38,829,206 sh (8.90%), Cohen & Steers, Inc. 36,331,844 sh (8.33%), State Street Corporation 22,241,227 sh (5.10%). All four fresh Q2 2026 13F figures used in this file are higher in share count than these stale 13G snapshots, consistent with accumulation ahead of and continued holding through the buyback-driven float shrink described above.
• The DEF 14A's 'Directors, director nominees and executive officers as a group (17 persons total)' held only 401,247 shares (well under 1%) as of 23 Mar 2026: immaterial and not included as a register row. Crown Castle has no founder or dual-class structure; Elliott Investment Management L.P. had a Cooperation Agreement with the board from December 2023 but does not appear in the 2026 proxy's beneficial-ownership table, so it is not treated as a current strategic holder.
• T. Rowe Price Investment Management, Inc. (CIK 1897612), a separate registrant from T. Rowe Price Associates, Inc., was checked per the chunk-19-27 lesson on this exact family and found to hold zero shares of Crown Castle in its Q2 2026 13F-HR: this is recorded here as a note, not a null row, per the 'holder that holds nothing' rule.
• Three of the four Capital Group registrants swept (Capital International Sarl CIK 1065349, Capital International Investors CIK 1562230, Capital Research Global Investors CIK 1422848) were checked and hold zero shares of Crown Castle in Q2 2026; only Capital World Investors (CIK 1422849) holds. Recorded as a note within the Capital Group row's method_note rather than as separate null rows.
