AMETEK, 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 1,136 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

• Holdings are empty by design, a sourced finding rather than a gap. The Q2 2026 10-Q (period ended 30 Jun 2026, filed 4 Aug 2026) and the FY2025 10-K (filed 17 Feb 2026) were both searched in full text for 'equity method', 'joint venture', 'unconsolidated', 'noncontrolling interest', 'non-controlling', 'controlling interest', 'non-marketable equity', 'minority interest', 'strategic investment', 'investment in unconsolidated', 'variable interest entity' and 'VIE'. Every one of these returned zero hits in BOTH filings except 'strategic investment' (one hit, an HR/talent-development sentence about employee development, not an investee) and 'VIE' (19 hits in the 10-K, all incidental substring matches inside unrelated words like 'review', 'active', 'services', none referring to a Variable Interest Entity). This is consistent with AMETEK's business model described in the brief: it grows almost entirely by acquiring businesses OUTRIGHT (wholly owned operating subsidiaries), which the brief explicitly excludes, rather than by taking minority or joint-venture stakes.
• The only 'equity securities' language found in the 10-K (11 hits) is the defined-benefit pension plan's fair-value asset table ('U.S. equity securities and global equity securities categorized as level 1 are traded on national and international exchanges...') and the Issuer Purchases of Equity Securities disclosure (AMETEK's own buyback table). Per the brief, a pension plan's investment portfolio is explicitly NOT a holding, so none of this table's line items (which are not individually named companies in any case, just asset-class buckets measured at fair value or net asset value) appear in holdings.
• AMETEK has a single class of common stock ($0.01 par value, one vote per share) and no dual-class or founder-control structure. Chairman and CEO David A. Zapico's beneficial ownership, individually and as part of the 16-person officer/director group, is each listed as less than 1% of outstanding common stock in the 2026 proxy.
• Register cross-check against the proxy's own 5%-holder table. The 2026 proxy (based on stale Schedule 13G/A filings: Vanguard as of 29 Dec 2023 filed 13 Feb 2024, BlackRock's underlying 13G date not stated in the excerpt read) names only two 5%+ holders as of 1 Mar 2026: The Vanguard Group, Inc. at 25,576,892 shares (11.0%) and BlackRock, Inc. at 17,317,217 shares (7.5%). No one unexpected surfaced beyond these two, both of which are also the top two rows in the 13F-based register below. The register instead uses each manager's Q2 2026 Form 13F-HR (30 Jun 2026 position date) as the more current figure: Vanguard's eight successor entities sum to 27,274,508 shares (11.90%) and BlackRock is 19,533,471 shares (8.52%), both higher than the stale 13G figures, consistent with continued accumulation since Dec 2023/the 13G date rather than a data error.
• Percentages are computed against 229,261,244 common shares outstanding as of 28 Jul 2026 (Q2 2026 10-Q cover page) for every register row, including the two proxy-sourced insider rows valued as of the proxy's 8 Jan 2026 record date (the proxy itself only states 'less than 1%' rather than a precise figure for insiders).
• Internal price cross-check across the 13F rows: BlackRock ($4,725,928,080 / 19,533,471 sh = $241.98), State Street ($2,502,296,386 / 10,342,632 sh = $241.94), Norges Bank ($1,041,156,854 / 4,303,368 sh = $241.94) and the rescaled T. Rowe Price figures ($241.97 and $241.98) all cluster tightly around $242.00 per share as of 30 Jun 2026, which is what confirmed the T. Rowe thousands-convention rescale (its raw, unscaled figures implied $0.24/share, about 1000x too low) rather than treating it as a genuine outlier.
• Market capitalisation of $57.11 billion and the $249.13 share price are stockanalysis.com's figures as of 18 Aug 2026, 12:43pm EDT (intraday). Cross-check: 229,261,244 shares x $249.13 implies approximately $57.12 billion, matching the reported market cap closely. No stock split was found: the 10-Q and 10-K were searched for 'stock split', 'two-for-one' and 'forward split' with zero hits, and the balance sheet's issued-share progression (270,471,745 issued less 41,434,441 treasury = 229,037,304 at 31 Dec 2025) is continuous with the 229,261,244 outstanding at 28 Jul 2026, consistent with ordinary buybacks/issuances rather than a split.
• Self-gate check, computed with the chart's own arithmetic (member rows at full value, only the aggregate they roll into is reduced by that value): 15 register rows (13 institutional/13F rows plus 2 insider rows). Members map: Zapico's 579,197 shares roll into the 16-person group. The group's raw 1,237,680 shares is reduced to a residual of 658,483 (1,237,680 minus 579,197); every other row, including Zapico's own row, counts at full value. Total = 93,809,765 shares against 229,261,244 shares outstanding, or 40.92%, within the expected 25 to 45 percent range.
