The Cooper Companies, 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 663 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

• Cooper's fiscal year ends 31 October, offsetting its filing calendar from the calendar year. The newest filing by date as of this research (20 Aug 2026) is the Q2 FY2026 10-Q (period ended 30 Apr 2026), filed 5 Jun 2026, which is newer than the FY2025 10-K (period ended 31 Oct 2025, filed 5 Dec 2025). The 10-Q's cover page states 195,030,630 shares of common stock outstanding as of 1 Jun 2026; this is the shares_outstanding basis used throughout this file. Cooper's Q3 FY2026 10-Q (period ending 31 Jul 2026) had not yet been filed as of 20 Aug 2026.
• Cooper effected a 4-for-1 stock split of its common stock on 16 Feb 2024 (confirmed from the FY2025 10-K, Note 1). All amounts in this file (register 13F share counts, shares_outstanding, proxy insider holdings) are on the current, post-split basis: 13F filings for periods after Feb 2024 report natively on the post-split basis, and the FY2025 10-K and 2026 DEF 14A both state that all historical share and per-share figures have been retroactively adjusted to reflect the split. No pre-split figures were mixed into this file.
• Holdings side searched in full and found empty of material equity stakes in other companies. Searched the newest 10-K (FY2025, filed 5 Dec 2025) and newest 10-Q (Q2 FY2026, filed 5 Jun 2026) for: 'equity method', 'equity investment', 'non-marketable', 'joint venture', 'cost method', 'investments in affiliates', 'variable interest entity', 'unrealized gain'. CooperVision and CooperSurgical are wholly owned operating segments, not holdings, and are excluded per the project's rules. Exhibit 21 (FY2025 10-K subsidiaries list) was checked and carries NO ownership-percentage column: every entity listed is stated to be wholly owned by Cooper or by a wholly-owned subsidiary, a genuine negative rather than evidence of looking in the wrong place. The 10-K's Note 3 'Acquisitions and Joint Venture' section, despite its title, describes only wholly-consolidated acquisitions (e.g. a fertility company specializing in sperm separation devices, acquired 7 Jun 2024 as an asset acquisition for $33.5 million) and generic fair-value accounting policy language mentioning 'joint venture interest' in the abstract (as a category of Level 3 fair-value measurement), not an actual disclosed joint venture holding.
• Both the FY2025 10-K and the Q2 FY2026 10-Q disclose, in one sentence each within MD&A, 'a loss on the disposal of a minority interest investment' recognized in fiscal 2025 (quantified in the 10-Q as a $15.7 million loss), which increased 'Other expense, net'. Neither filing names the investee, states the ownership percentage held, the size of the original investment, or the sale proceeds; the disclosure is limited to the one line explaining a year-over-year expense variance. Because Cooper has already exited this position and no name or size is disclosed, per the project's rule this is recorded here as a note rather than as a null holdings row: it is evidence Cooper has historically held at least one minority equity investment, now disposed of, not evidence of a current holding.
• Register: 12 rows, share total 91,724,315 (officers-group container reduced to its residual of 2,118,794 after removing Albert G. White III's 1,944,945-share member row; every other row counted at full value), 91,724,315 / 195,030,630 = 47.03% of shares_outstanding. Computed on this final file using the project's exact chart formula (container reduced to residual, members and non-aggregate rows at full value).
• Vanguard: parent CIK 0000102909 filed Form 13F-NT (no holdings) for Q2 2026, so the successor entities were summed. Entities/CIKs summed: Vanguard Fiduciary Trust Co 0000933478, Vanguard Investments Australia Ltd 0001550100, Vanguard Asset Management Ltd 0001680208, Vanguard Personalized Indexing Management LLC 0001767306, Vanguard Global Advisers LLC 0001811242, Vanguard Capital Management LLC 0002100119, Vanguard Portfolio Management LLC 0002100121 (7 entities, all identified from data/registers/COO.json; no additional 8th entity, e.g. Vanguard National Trust Co, was found reporting a Q2 2026 13F for this register's snapshot, so 7 is the full family found).
• Capital Group: checked all 6 registrants (the 4 in this project's register snapshot plus the 2 additional entities the project brief names). Only Capital World Investors (CIK 0001422849) currently holds COO; the other 5 report zero. The family's position fell sharply between the 31 Mar 2026 register snapshot (7,812,099 sh) and the fresh Q2 2026 13F-HR figures used here (591,128 sh), and separately the proxy's own stale 13G citation (10,973,924 sh as of 30 Sep 2025) confirms a large, multi-quarter sell-down rather than a data error; both figures are kept in the row's method_note for reconciliation.
• T. Rowe Price: checked both registrants named in the project brief. T. Rowe Price Associates, Inc. (CIK 0000080255) and T. Rowe Price Investment Management, Inc. (CIK 0001897612) both hold COO and both report VALUES IN THOUSANDS on their Q2 2026 13F-HR information tables, the same defect documented on nine prior companies in this project; both were rescaled by 1000x before being summed into the single 'T. Rowe Price' row.
• Browning West, LP is classified holder_type 'strategic' rather than 'active' because the 2026 DEF 14A discloses a letter agreement (dated 22 Dec 2025) under which Cooper appointed a Browning West nominee, Walter M Rosebrough, Jr., to the Board ahead of the 2026 Annual Meeting. This is the clearest evidence of strategic/activist influence found in this research; no SC 13D from Browning West was located on EDGAR (searched all SC 13D and SC 13D/A filings against CIK 0000711404, which returns only decades-old, unrelated 1990s filings), so the classification rests on the proxy's board-appointment disclosure, not a 13D.
• JANA Partners Management, LP holds 3,582,480 shares (1.84%) per its own Q2 2026 13F-HR but is classified 'active', not 'strategic': COO's 2026 DEF 14A was searched for 'JANA' and returned zero hits, so no board seat, cooperation agreement, or other strategic relationship with Cooper is evidenced in the filings actually read for this research, unlike Browning West.
• Kayne Anderson Rudnick reports COO under the issuer name 'COOPER COMPANIES INC' rather than the 'COOPER COS' spelling used by every other filer checked in this register; the fragment search initially returned no match and had to be retried with the shorter fragment 'COOPER' before the position was found. Recorded here as a spelling-quirk finding per the project's evidence-of-absence guidance.
• The DEF 14A's own 5%-owner table is abbreviated to only 3 rows (Vanguard, BlackRock, Capital World Investors), all sourced to older Schedule 13G/A filings (Vanguard as of 29 Dec 2023, BlackRock as of 31 Mar 2025, Capital World Investors as of 30 Sep 2025); every one of those three figures is stale relative to the fresh Q2 2026 13F-HR figures used in this register, and the proxy figures are recorded in each row's own method_note for reconciliation rather than used directly.
