Mettler-Toledo International, 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 807 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

• Extremely small float: shares_outstanding is 20,036,559 as of 30 Jun 2026 (10-Q cover page, 'The Registrant had 20,036,559 shares of Common Stock outstanding at June 30, 2026'), with a share price above $1,270 for most of Q2 2026. This makes the register's percentages large relative to a typical company at similar market cap; treat that as expected given the float, not an error.
• Implied-price check run on EVERY register row: value_usd / shares. Nine of eleven rows (Vanguard family entities, BlackRock, Capital Group family entities, State Street, T. Rowe Price family (after the thousands correction), Morgan Stanley, Goldman Sachs, PineStone) land exactly on $1,277.51, MTD's 30 Jun 2026 closing price implied by the cluster. Geode is $1,274.94 (-0.2%) and AllianceBernstein is $1,261.20 (-1.3%); neither shows the 10x or 1000x pattern that would indicate a units error (unlike T. Rowe Price, whose two CIKs file the value column in THOUSANDS and were corrected by x1,000 to rejoin the $1,277.51 cluster), so both were left as reported and flagged as ordinary valuation-date variance.
• Holdings side is empty. Searched the FY2025 10-K (filed 6 Feb 2026, https://www.sec.gov/Archives/edgar/data/1037646/000103764626000011/mtd-20251231.htm) and the Q2 2026 10-Q (filed 31 Jul 2026, https://www.sec.gov/Archives/edgar/data/1037646/000103764626000051/mtd-20260630.htm) for 'equity method', 'equity investment(s)', 'joint venture', 'unconsolidated', 'non-marketable'/'nonmarketable', 'minority interest', 'variable interest entity', 'noncontrolling interest', 'investments in', 'partly owned', '% owned', 'majority-owned', 'affiliate'. Zero substantive hits in either filing (the only 'equity investment' matches were unrelated insurance-company counterparty names in the pension footnote). Exhibit 21 to the FY2025 10-K (https://www.sec.gov/Archives/edgar/data/1037646/000103764626000011/mtd_exhibit2112312025.htm) lists roughly 190 subsidiaries by country and legal name only, with NO ownership-percentage column (the same bare-list shape as Labcorp and Darden in this project, not the percentage-column shape that found partly-owned entities at Expeditors, Jacobs, Quest, and PPG). Mettler-Toledo's structure appears to consist entirely of wholly owned operating subsidiaries, with no equity-method investments, joint ventures, minority stakes, or VIEs disclosed anywhere searched. This is a sourced negative finding, not a gap.
• Fundsmith exit: the project's own 31 Mar 2026 register snapshot (data/registers/MTD.json) showed Fundsmith LLP holding 568,516 shares and Fundsmith Investment Services Ltd. holding 222,759 shares of MTD. Both entities' fresh Q2 2026 13F-HR filings (Fundsmith LLP, filed 14 Aug 2026, accession 0001569205-26-000012, https://www.sec.gov/Archives/edgar/data/1569205/000156920526000012/FLLPq22026.xml; Fundsmith Investment Services Ltd., filed 14 Aug 2026, accession 0001868537-26-000007, https://www.sec.gov/Archives/edgar/data/1868537/000186853726000007/FISLq22026.xml) contain no MTD row at all under CUSIP 592688105, checked against 'METTLER' and 'TOLEDO' fragments in each 41- and 27-line portfolio. Recorded as a full exit between Q1 and Q2 2026; no row.
• Self-gate, computed from the final file on disk exactly as the chart computes it: 11 register rows, no member rows roll up into any container (the officers/executives row is a standalone aggregate with no listed sub-members), so total = sum of raw shares across all 11 rows = 10,457,070 shares = 52.19% of shares_outstanding (20,036,559). This sits just inside the brief's 15-55% band; the small 20.0m-share float with heavy index and active-manager concentration (the top 3 alone, Vanguard/BlackRock/Capital Group families, are already 30.0%) explains the level, similar to the documented Fair Isaac precedent (59.8% on a comparably small float).
• The 2026 DEF 14A's own 5% Shareholders table (Vanguard 2,513,052 sh/11.6%, BlackRock 1,666,731 sh/8.0%, Capital International Investors 1,024,636 sh/5.0%) is sourced to stale Schedule 13Gs (Vanguard 13 Feb 2024, BlackRock 24 Apr 2025, Capital International Investors 13 Feb 2026). Per the brief, the fresh Q2 2026 13F figures used in the register rows above supersede these; the proxy's stale figures are recorded here only as a reconciliation, not used in any row.
