Moody's Corporation

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 1,357 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

• No 13F filings: Moody's Corporation itself (CIK 0001059556) does not appear to file Form 13F; its EDGAR submissions feed lists only 10-K, 10-Q, DEF 14A and similar corporate filings, no 13F-HR/NT. Moody's is a ratings and analytics company, not an investment manager, so this is expected and no client-asset exclusion analysis (of the kind needed for Ameriprise or PNC) is required here.
• Berkshire Hathaway is Moody's single largest and most strategically significant holder: 24,669,778 shares (14.25%) per its own Q2 2026 13F-HR, identical to the position size disclosed in a Schedule 13G/A filed 14 Feb 2014 (as of 31 Dec 2013) and repeated in Moody's 2026 proxy's 5% Owners table. The position appears to have been essentially unchanged for over a decade, consistent with Warren Buffett's public description of Moody's as a long-term core holding. Classified holder_type 'strategic' rather than 'active' given this multi-decade concentrated, non-index nature.
• Vanguard case: parent CIK 0000102909 filed Form 13F-NT (notice, no holdings) for Q2 2026, so per the brief's rule the position is the sum of its successor filers, not a substitution. Two successors held MCO: Vanguard Capital Management LLC (CIK 0002100119, 9,757,973 shares) and Vanguard Portfolio Management LLC (CIK 0002100121, 3,733,380 shares), summed to 13,491,353 shares in the single Vanguard register row. Other Vanguard-affiliated 13F filers (e.g. Vanguard Advisers Inc, Vanguard Fiduciary Trust Co) were not individually checked; see unknowns.
• Capital Group family: all three entities checked for Q2 2026 MCO holdings. Capital World Investors (CIK 0001422849): zero (checked by CUSIP 615369105 and by name-fragment search, no match). Capital International Investors (CIK 0001562230): zero, same check. Capital Research Global Investors (CIK 0001422848): 647 shares, $293,039. The family total (647 shares, about 0.0004% of MCO) is immaterial and is not included as a register row; it is reported here for completeness per the brief's explicit Capital Group check requirement.
• T. Rowe Price family: both entities checked. T. Rowe Price Associates, Inc. (CIK 0000080255) holds 1,545,468 shares (see the thousands-trap method_note on its register row). T. Rowe Price Investment Management, Inc. (CIK 0001897612), the separate registrant, filed its own Q2 2026 13F-HR and holds zero MCO shares, checked by CUSIP and by name-fragment search across its full info table.
• Holdings side: two named equity-method/measurement-alternative investees (CCXI and BitSight) were identified in the Q2 2026 10-Q and FY2025 10-K, but their individual dollar values could not be sourced because both are the largest components of combined balances covering multiple unnamed investees: 'Equity method investments' totaled $112 million at 30 Jun 2026 (CCXI is 'the most significant'), and 'Investments measured using the measurement alternative' totaled $350 million at 30 Jun 2026 (BitSight is 'the most significant'). Per the rule against assigning a combined balance to one investee, both holdings carry value_usd: null. CCXI's ownership percentage (30%) is separately and explicitly disclosed in the 10-K glossary, so that field is populated even though the dollar value is not. Total investments in non-consolidated affiliates were $483 million at 30 Jun 2026 ($112m equity method + $350m measurement alternative + $21m other).
• ICRA Limited is included as a third holding even though Moody's consolidates it (majority, non-wholly-owned subsidiary, ~51.87% per aggregator data), because it remains a separately NSE/BSE-listed Indian company with its own public minority shareholders, unlike Moody's other wholly owned foreign rating-agency subsidiaries (e.g. Global Credit Rating Company entities, ICR Chile) which were left out of holdings as ordinary wholly owned operating subsidiaries. The exact ownership percentage and ICRA's own share count and price were not found in any Moody's SEC filing searched (10-K, 10-Q, Exhibit 21 all confirm the subsidiary relationship and consolidation but not the percentage), so this row is sourced entirely from aggregators (trendlyne.com for the ownership percentage, stockanalysis.com for ICRA's share count and price) rather than a filing; basis is 'aggregator' throughout, not 'filed_10q_10k', even though Moody's own filings corroborate the qualitative relationship.
• ICR Chile (Compania Clasificadora de Riesgo Limitada, Chile), acquired Q3 2025 per the 10-K glossary, and the various wholly owned Global Credit Rating Company entities (Nigeria, Senegal, South Africa) and ICRA Analytics/ICRA ESG Ratings/ICRA Lanka/ICRA Nepal subsidiaries listed in Exhibit 21 were reviewed and treated as ordinary consolidated operating subsidiaries; no evidence was found that any of them is separately publicly traded, so none is included as a holding.
• Self-gate: 16 register rows (14 institutional/13F rows plus 2 insider rows). Members = Robert Fauber's 157,581 shares, rolled into the 'All current directors and executive officers as a group' container, whose residual counts at 249,115 - 157,581 = 91,534. Sum: Berkshire 24,669,778 + Vanguard 13,491,353 + BlackRock 12,461,878 + State Street 7,111,386 + FMR 4,985,040 + Geode 4,006,816 + Morgan Stanley 2,379,424 + Norges Bank 2,372,048 + Northern Trust 1,671,990 + T. Rowe Price 1,545,468 + Schwab 1,201,108 + MFS 1,186,385 + Bank of America 642,955 + JPMorgan 539,316 + Fauber 157,581 + group residual 91,534 = 78,514,060 shares, or 45.34% of 173,180,984 shares outstanding. This sits just above the brief's typical 25-45% band but well under the 55% hard ceiling; the concentration is explained by Berkshire's unusually large single strategic stake (14.25%) on top of the standard large-cap index/active manager cluster, not by a mixed instrument, basis error, or double count.
• Moody's has a single class of common stock (par value $0.01, one vote per share) and no dual-class or founder-control structure; Robert Fauber (President and CEO) and the full 13-person director/officer group each hold well under 1% of outstanding shares per the 2026 proxy.
