Cincinnati Financial 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 906 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

• Cincinnati Financial is a property-casualty insurer that holds a large common-stock equity portfolio on its own (consolidated) balance sheet, not client assets, so it is in scope for the holdings side under the brief. Its fixed-maturity/bond portfolio is excluded as a treasury holding.
• CINF's equity portfolio is split across FIVE affiliated 13F-HR filers for the same reporting period (2026-06-30): the parent, Cincinnati Financial Corporation (CIK 0000020286, 56 positions, $5.232bn), plus four wholly-owned insurance subsidiaries that each file their own 13F: Cincinnati Insurance Co (0001279885, 64 positions, $6.941bn), Cincinnati Specialty Underwriters Insurance Co (0001426763, 45 positions, $0.449bn), Cincinnati Casualty Co (0001279888, 24 positions, $0.188bn), and Cincinnati Indemnity Co (0001279886, 11 positions, $0.041bn). Summed and matched by CUSIP, these five filers report 64 unique issuers totaling $12,851,987,673 as of 2026-06-30, which reconciles closely with the FY2026 Q2 10-Q's own disclosure of 'equity investments, with a fair value totaling $13.194 billion at June 30, 2026, included $12.883 billion of common stock securities' (the 10-Q figure also includes some non-13(f) items). Using only the parent CIK's 13F, as a single-filer approach would, understates the true portfolio by roughly 60%, so all five filers were summed for every holding in this file.
• A sixth affiliated filer, Cincinnati Life Insurance Co (CIK 0001279887), filed 13F-HR for Q3 2025 but has NO 2026 filings; its (likely small) equity holdings are therefore not captured in the 2026-06-30 figures above.
• Holdings side selection: the combined 5-filer portfolio has 64 distinct issuers worth $12.85bn total. This file lists the 30 largest by value (81.1% of total portfolio value, from Apple at $1.004bn down to Automatic Data Processing at $130.1m), plus Honeywell International and the newly spun-off Honeywell Aerospace Technologies Corp (ranks 36 and 38, both at 566,250 shares, reflecting CINF's post-spinoff distribution) included for the spinoff story. The remaining ~32 smaller issuers (each under $130m, from WEC Energy Group down to a small position in HL Acquisition Inc DBA Hosta) are omitted for size.
• Cross-holdings already in this database: Cincinnati Financial holds Apple, Microsoft, Lam Research, Broadcom, AbbVie, Cisco, JPMorgan Chase, Analog Devices, Cummins, Johnson & Johnson, Dover, UnitedHealth, TJX, Qualcomm, Philip Morris International, Norfolk Southern, Home Depot, RTX, Valero, McDonald's, CME Group, Air Products, Snap-on (also Cincinnati-headquartered), PepsiCo, Microchip Technology, Procter & Gamble, ExxonMobil, Mondelez, U.S. Bancorp and Honeywell (Honeywell Technologies), all of which have their own research files in data/research/ that supplied the shares_outstanding used for pct_of_target here.
• value_price_per_share was cross-checked against each target's own market_cap_usd/shares_outstanding in this database where available (e.g. Cisco: 13F-implied $117.46 on 2026-06-30 vs this database's $113.61 on 2026-08-14) and found consistent, confirming 13F 'value' fields for these 2026 filings are already in whole US dollars, not thousands.
• Register: T. Rowe Price files its 13F 'value' column in THOUSANDS on both registrant CIKs; the T. Rowe Price Associates figure here ($42,114,000) has been corrected from the raw filed value of 42114 (thousands).
• T. Rowe Price Investment Management, Inc. (CIK 0001897612) and all three Capital Group registrants (Capital World Investors 0001422849, Capital International Investors 0001562230, Capital Research Global Investors 0001422848) were checked directly against their own Q2 2026 13F-HR information tables for CUSIP 172062101 and hold NO Cincinnati Financial position as of 2026-06-30. Recorded here as checked-and-zero, not as rows.
• Vanguard: the parent Vanguard Group Inc (CIK 0000102909) filed Form 13F-NT (a notice carrying no holdings) for Q2 2026, so per the project's standard rule the eight successor entities were summed to 19,921,810 shares as the family total (Vanguard Fiduciary Trust Co, Vanguard Investments Australia, Vanguard Asset Management Ltd, Vanguard Personalized Indexing Management, Vanguard Global Advisers, Vanguard National Trust Co, Vanguard Capital Management LLC, Vanguard Portfolio Management LLC). The entity list was sourced from this project's own data/registers/CINF.json snapshot (period 31-Mar-2026); the share figures used here are each entity's own fresh Q2 2026 (2026-06-30) 13F-HR filing, not the stale snapshot.
• The DEF 14A (filed 2026-03-18, ownership as of 2026-03-04) lists three 5%+ holders (Vanguard 12.32%, BlackRock 7.81%, State Street 6.24%) but sources them to Dec 2023 Form 13G/A filings, which are far staler than the fresh Q2 2026 13F-HR figures used in this register (Vanguard 12.98% combined, BlackRock 8.22%, State Street 5.56% of the current, larger share count). The fresh 13F figures are used here rather than the proxy's stale 13G citations.
• Insider/founder-family holding: Charles O. Schiff (CEO, Secretary and Treasurer of John J. & Thomas R. Schiff & Co. Inc., a director) held 1,173,206 shares (0.75%) per the March 2026 proxy, the largest individual holding among directors and named executive officers, reflecting the Schiff family's long association with Cincinnati Financial's founding insurance agency network. CEO Steven J. Johnston held 893,652 shares (0.57%), the second largest. Both are individually named within the proxy's 'Other Directors and Named Executive Officers' table, which the proxy's own 'All directors and nondirector executive officers as a group (30 individuals)' total (4,584,495 shares, 2.94%) already includes, so they are marked rolls_up_into that aggregate row here to avoid double-counting.
• Self-gate (computed from the final file, matching the chart's own arithmetic exactly): 13 register rows, raw share total after reducing the aggregate row by its two named members (Schiff + Johnston, 2,066,858 shares) = 59,790,512 shares, which is 38.96% of shares_outstanding (153,478,045 as of 2026-07-22). This is within the expected 25-45% band.
• shares_outstanding (153,478,045) is from the cover page of CINF's own Q2 2026 10-Q (filed 2026-07-27, dated as of 2026-07-22). market_cap_usd is computed from that share count and a stockanalysis.com closing price of $171.35 on 2026-08-18.
