Cintas 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 1,416 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

• Cintas completed a four-for-one stock split, in the form of a stock dividend, announced 2 May 2024. Shareholders of record 4 Sep 2024 received three additional shares per share held, distributed after market close 11 Sep 2024, trading post-split from 12 Sep 2024 (FY2026 10-K). This falls well before every source date used in this file: the Q2 2026 13F-HRs (as of 30 Jun 2026) and the DEF 14A filed 16 Sep 2025 (which states its share amounts are 'as adjusted to reflect the Stock Split') are both natively post-split, so no cross-basis restatement of the register was needed. The implied-price-per-share check (value_usd / shares) across all twelve Q2 2026 13F rows clusters at approximately $170, consistent with CTAS's trading range as of 30 Jun 2026, confirming a consistent post-split basis rather than a split-ratio-off outlier. The one outlier found was T. Rowe Price, whose 13F XML reports its value column in thousands of dollars ($978,131 for 5,750,996 shares, implying $0.17/share); this is the classic thousands-convention defect (brief rule 10), not a split defect, and value_usd for that row is restated x1,000 with the as-filed figure preserved in method_note.
• Holdings: an empty array is a deliberate, sourced finding, not an omission. The FY2026 10-K (period ended 31 May 2026, filed 29 Jul 2026, the most recent Cintas filing given its May fiscal year end) was searched in full text for 'equity method', 'unconsolidated', 'joint venture', 'noncontrolling', 'minority interest', 'investment in', 'affiliate', 'equity securities' and 'cost method'. Zero hits for equity method, unconsolidated, joint venture, noncontrolling and minority interest. The only 'equity investment' hit concerns diversified pension plan trust assets, not a strategic corporate stake. The only 'affiliate' hits are boilerplate (non-affiliate market value on the 10-K cover, an 'Affiliated Purchases' table heading for Cintas' own share buybacks, and a subsidiary-guarantor exhibit index heading), not an investee relationship. Cintas is a uniform rental, facility services and safety products company; nothing in the FY2026 10-K indicates it holds equity-method investees, joint ventures or minority stakes in other companies.
• Vanguard: this is the 13F-NT successor case (brief rule 7), not the aggregate case used for the Capital Group family below. Vanguard Group Inc (CIK 0000102909) filed a 13F-NT (notice only) for Q2 2026, so its position is reported entirely by two successor entities, Vanguard Capital Management LLC and Vanguard Portfolio Management LLC, which are summed into one 'The Vanguard Group' row (35,657,721 shares) without setting is_aggregate.
• Capital Group: checked all three separately registered Capital Group Companies 13F filers named in the brief, Capital World Investors (CIK 0001422849), Capital International Investors (CIK 0001562230) and Capital Research Global Investors (CIK 0001422848). None of the three held a Cintas position (CUSIP 172908105) in their Q2 2026 13F-HR filings; tried both the 'CINTAS' and shorter 'CINT' fragments against each info table with zero matches in all three, so this is a genuine absence, not a spelling miss. This is explicitly NOT the Vanguard 13F-NT successor case; these are three independently filing advisers within one investment-management family, and here the family simply has no reportable Cintas stake this quarter, so no Capital Group row appears in the register.
• Farmer family: Scott D. Farmer, Cintas' Executive Chairman of the Board and son of founder Richard T. Farmer, beneficially owns 57,662,934 shares (14.3%) per the Sep 2025 DEF 14A, held directly and indirectly through Summer Hill Partners, LLLP and related family entities and trusts. He is a sitting director and executive officer, so per the proxy's own beneficial-ownership table structure his stake sits INSIDE the 'All Directors and Current Executive Officers as a Group (12 persons)' aggregate (60,060,486 shares, 14.9%), not in a separate outside container: this was not assumed, it follows directly from the proxy listing him within that table with the other 11 directors/NEOs and the group total including his shares. This register therefore marks Farmer's row with rolls_up_into pointing at the group row, and the group row as is_aggregate with a residual_label, per rule 8.
• No Schedule 13D or 13G has been filed on Cintas common stock since 13 Feb 2024, per the EDGAR filing index for CIK 0000723254 (checked through 17 Aug 2026), so no fresh 13D/G supplements the register. The Sep 2025 proxy's own Principal Shareholders table cites Vanguard Group Inc at 41,197,032 shares (10.2%) and BlackRock Inc at 28,799,136 shares (7.1%), both sourced explicitly (per the proxy's own footnotes) from stale Schedule 13G/A filings dated Jan/Feb 2024 reporting positions as of 29 Dec 2023 / 31 Dec 2023, share-split-adjusted but otherwise nearly two years old by the time of this research. These proxy figures diverge materially from the fresh Q2 2026 13F sums used in the register (35,657,721 and 26,578,230 shares respectively): the register uses the newer 13F data as instructed, and this note records the disagreement per rule 6 of the general research brief.
• Percentages for the twelve institutional 13F rows are computed against 400,169,561 shares outstanding as of 30 Jun 2026 (FY2026 10-K cover page, the most recent Cintas SEC filing given its 31 May fiscal year end). The two proxy-sourced rows (Farmer, and the D&O group) instead use the proxy's own reported percentages and denominator (shares outstanding as of 2 Sep 2025), since the proxy does not disclose that raw share count separately.
• Market capitalisation ($79.16bn) and share price ($197.82) are stockanalysis.com's figures as of 17 Aug 2026, close. Cross-check: 400,169,561 shares x $197.82 implies approximately $79.17bn, consistent with the reported $79.16bn market cap.
• Self-gate check: 14 register rows. Summing the twelve non-aggregate institutional rows (119,158,598 shares) plus Farmer's full 57,662,934 shares (a member row, counted at full value) plus the D&O aggregate row reduced by Farmer's rolled-up shares (60,060,486 - 57,662,934 = 2,397,552) gives 179,219,084 shares against 400,169,561 shares outstanding, or 44.78%, within the expected 25 to 45 percent range.
