Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated condensed financial statements of Cintas Corporation (Cintas, the Company, we, us or our) included herein have been prepared by Cintas, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with United States generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. While we believe that the disclosures are adequately presented, we suggest that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2024 (Annual Report) filed with the SEC on July 25, 2024. See Note 1 entitled Significant Accounting Policies of "Notes to Consolidated Financial Statements" of that Annual Report for a summary of our significant accounting policies. There have been no material changes in the accounting policies followed by Cintas during the current fiscal year. Interim results are subject to variations and are not necessarily indicative of the results of operations for a full fiscal year. In the opinion of management, adjustments (which include only normal recurring adjustments) necessary for a fair statement of the consolidated results of the interim periods shown have been made. Inventories are valued at the lower of cost (first-in, first-out) or net realizable value. Inventories, net are comprised of the following at: (In thousands) August 31, May 31, Raw materials $ 13,926 $ 16,664 Work in process 47,536 48,458 Finished goods 337,616 345,079 Inventories, net $ 399,078 $ 410,201 Inventories are recorded net of reserves for obsolete inventory (excess and slow-moving) of $65.2 million and $63.1 million at August 31, 2024 and May 31, 2024, respectively. The inventory obsolescence reserve is determined by specific identification, as well as an estimate based on Cintas' historical rates of obsolescence. Once a specific inventory item is written down to the lower of cost or net realizable value, a new cost basis has been established, and that inventory item cannot subsequently be marked up. Stock Split On May 2, 2024, the Company announced a four-for-one split of its common stock (the Stock Split), in the form of a stock dividend. Shareholders of record, as of September 4, 2024, received three additional common stock shares for each common share held, which were distributed after market close on September 11, 2024. The Company's common stock shares began trading on a post Stock-Split basis after the market opening on September 12, 2024. All references made to common stock shares, equity awards, common stock per share amounts and treasury stock shares in the accompanying consolidated condensed financial statements and applicable disclosures have been retroactively adjusted to reflect the effects of the Stock Split. . New Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures (ASU 2023-07). ASU 2023-07 requires additional disclosures pertaining to significant expenses and other items of an entity’s reportable operating segments. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 (fiscal 2025). Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-07 on the consolidated condensed financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures (ASU 2023-09), which expands disclosures in an entity’s income tax rate reconciliation table and regarding cash taxes paid both in the U.S. and foreign jurisdictions. ASU 2023-09 will be effective for annual periods beginning after December 15, 2024 (fiscal 2026). The Company is currently evaluating the impact of ASU 2023-09 on the consolidated condensed financial statements. There are no other accounting pronouncements recently issued or newly effective that had, or are expected to have, a material impact on Cintas' consolidated condensed financial statements.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The following table presents Cintas' total revenue disaggregated by operating segment for the three months ended August 31: (In thousands) 2024 2023 Uniform Rental and Facility Services $ 1,933,839 77.3 % $ 1,826,825 78.0 % First Aid and Safety Services 292,567 11.7 % 260,693 11.1 % Fire Protection Services 197,497 7.9 % 174,316 7.5 % Uniform Direct Sales 77,684 3.1 % 80,496 3.4 % Total revenue $ 2,501,587 100.0 % $ 2,342,330 100.0 % The Fire Protection Services and Uniform Direct Sales operating segments are included within All Other as disclosed in Note 10 entitled Segment Information. Revenue Recognition Policy Approximately 95% of the Company's revenue is derived from fees for route servicing of Uniform Rental and Facility Services, First Aid and Safety Services and Fire Protection Services customers, performed by a Cintas employee-partner, at the customer's location of business. Revenue from our route servicing customer contracts represent a single-performance obligation. The Company recognizes revenue over time as services are performed, based on the nature of services provided and contractual rates (output method) or at a point in time when the performance obligation under the terms of the contract with a customer are satisfied, at the customer's location of business. The Company's performance period generally corresponds with the monthly invoice period. The Company's remaining revenue, primarily within the Uniform Direct Sales operating segment, and representing approximately 5% of the Company's total revenue, is recognized when the obligations under the terms of a contract with a customer are satisfied. This generally occurs when the goods are transferred to the customer. We are exposed to credit losses primarily through our trade receivables. We determine the allowance for credit losses using both an estimate, based on historical rates of collections, and reserves for specific accounts identified as uncollectible. The portion of the allowance for credit losses that is an estimate based on Cintas' historical rates of collections is recorded for overdue amounts, beginning with a nominal percentage when the account is current and increasing substantially as the account ages. The amount provided as the account ages will differ slightly between the Uniform Rental and Facility Services reportable operating segment, the First Aid and Safety Services reportable operating segment and All Other because of differences in customers served and the nature of each business. We update our allowance for credit losses quarterly, considering recent write-offs and collections information and underlying economic expectations. Costs to Obtain a Contract The Company capitalizes commission expenses paid to our employee-partners when the commissions are deemed to be incremental for obtaining the route servicing customer contract. Capitalized commissions are classified as current or noncurrent based on the timing of when we expect to recognize the expense. The current portion is included in prepaid expenses and other current assets, and the noncurrent portion is included in other assets, net on the Company's consolidated condensed balance sheets. As of August 31, 2024, the current and noncurrent assets related to capitalized commissions totaled $95.0 million and $265.9 million, respectively. As of May 31, 2024, the current and noncurrent assets related to capitalized commissions totaled $94.6 million and $262.5 million, respectively. The Company recorded amortization expense related to capitalized commissions of $25.9 million and $24.4 million during the three months ended August 31, 2024 and 2023, respectively. These expenses are classified in selling and administrative expenses on the consolidated condensed statements of income.

Leases

Leases	3 Months Ended
Leases	Aug. 31, 2024
Leases [Abstract]
Leases	Leases Cintas has operating leases for certain operating facilities, vehicles and equipment, which provide the right to use the underlying asset and require lease payments over the term of the lease. Each new contract is evaluated to determine if an arrangement contains a lease and whether that lease meets the classification criteria of a finance or operating lease. All identified leases are recorded on the consolidated condensed balance sheets with a corresponding operating lease right-of-use asset, net, representing the right to use the underlying asset for the lease term and the operating lease liabilities representing the obligation to make lease payments arising from the lease. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the consolidated condensed balance sheets. Operating lease right-of-use assets, net and operating lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term and include options to extend or terminate the lease when they are reasonably certain to be exercised. The present value of lease payments is determined primarily using the incremental borrowing rate based on the information available at lease commencement date. Lease expense for operating leases is recorded on a straight-line basis over the lease term and variable lease costs are recorded as incurred. Both lease expense and variable lease costs are primarily recorded in cost of uniform rental and facility services and other on the Company's consolidated condensed statements of income. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. Operating lease costs, including short-term lease expense and variable lease costs which were immaterial in both periods, were $21.8 million and $19.7 million for the three months ended August 31, 2024 and 2023, respectively. The following table provides supplemental information related to the Company's consolidated condensed statements of cash flows for the three months ended August 31: (In thousands) 2024 2023 Cash paid for amounts included in the measurement of operating lease liabilities $ 13,328 $ 12,696 Operating lease right-of-use assets obtained in exchange for new and renewed $ 13,973 $ 14,286 Other information related to the operating lease right-of-use assets, net and operating lease liabilities was as follows: August 31, May 31, Weighted-average remaining lease term 5.20 years 5.15 years Weighted-average discount rate 3.64% 3.48% The contractual future minimum lease payments of Cintas' operating lease liabilities by fiscal year are as follows as of August 31, 2024: (In thousands) 2025 (remaining nine months) $ 39,570 2026 47,203 2027 37,748 2028 31,759 2029 23,645 Thereafter 36,546 Total payments 216,471 Less interest (20,589) Total present value of lease payments $ 195,882

Fair Value Measurements

Fair Value Measurements	Aug. 31, 2024
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements All financial instruments that are measured at fair value on a recurring basis have been classified within the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the consolidated condensed balance sheet dates. These financial instruments measured at fair value on a recurring basis are summarized below: As of August 31, 2024 As of May 31, 2024 (In thousands) Level 1 Level 2 Level 3 Fair Value Level 1 Level 2 Level 3 Fair Value Cash and cash equivalents $ 101,373 $ — $ — $ 101,373 $ 342,015 $ — $ — $ 342,015 Other assets, net: Interest rate lock — 81,465 — 81,465 — 94,829 — 94,829 Total assets at fair $ 101,373 $ 81,465 $ — $ 182,838 $ 342,015 $ 94,829 $ — $ 436,844 Cintas’ cash and cash equivalents are generally classified within Level 1 of the fair value hierarchy. Financial instruments classified as Level 1 are based on quoted market prices in active markets. The types of financial instruments Cintas classifies within Level 1 include most bank deposits and money market securities. Cintas does not adjust the quoted market price for such financial instruments. The fair values of Cintas' interest rate lock agreements are based on similar exchange traded derivatives (market approach) and are, therefore, included within Level 2 of the fair value hierarchy. The fair value was determined by comparing the locked rates against the benchmarked treasury rate. No other amounts included in other assets, net, are recorded at fair value on a recurring basis. The methods described above may produce a fair value that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while Cintas believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the consolidated condensed balance sheet dates. In addition to assets and liabilities that are recorded at fair value on a recurring basis, Cintas records assets and liabilities at fair value on a nonrecurring basis as required under U.S. GAAP. The assets and liabilities measured at fair value on a nonrecurring basis primarily relate to assets and liabilities acquired in a business acquisition.

Earnings Per Share	Aug. 31, 2024
Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Cintas uses the two-class method to calculate basic and diluted earnings per share as a result of outstanding participating securities in the form of restricted stock awards.

The rate presented is the variable borrowing rate at August 31, 2024. (2) Cintas assumed these senior notes with the acquisition of G&K Services, Inc. (G&K) in the fourth quarter of fiscal 2017, and they were recorded at fair value. The interest rate shown above is the effective interest rate until repayment in fiscal 2025. Cintas' senior notes, excluding the G&K senior notes assumed with the acquisition of G&K in fiscal 2017, are recorded at cost, net of debt issuance costs. The fair value of the long-term debt is estimated using Level 2 inputs based on observable market prices. The carrying value and fair value of Cintas' debt as of August 31, 2024 were $2,486.6 million and $2,464.5 million, respectively, and as of May 31, 2024 were $2,486.6 million and $2,392.8 million, respectively. During the three months ended August 31, 2024, Cintas issued $166.0 million, net of commercial paper. During the three months ended August 31, 2023, Cintas repurchased, and subsequently retired, $10.0 million of its 6.15%, 30-year senior notes. In conjunction with these transactions Cintas recognized a loss of $0.8 million, which is recorded in interest expense on the consolidated condensed statements of income for the thre e months ended Au gust 31, 2023. The credit agreement that supports our commercial paper program has capacity under the revolving credit facility of $2.0 billion. The credit agreement has an accordion feature that provides Cintas the ability to request increases to the borrowing commitments under the revolving credit facility of up to $500.0 million in the aggregate, subject to customary conditions. The maturity date of the revolving credit facility is March 23, 2027. As of August 31, 2024, there was $166.0 million of commercial paper outstanding with a weighted average interest rate of 5.44% and no borrowings on our revolving credit facility. As of May 31, 2024, there was no commercial paper outstanding and no borrowings on our revolving credit facility. The fair value of the commercial paper, which approximates carrying value, is estimated using level 2 inputs based on observable market prices and interest rates. Cintas uses interest rate locks to manage its overall interest expense as interest rate locks effectively change the interest rate of specific debt issuances. The interest rate locks are entered into to protect against unfavorable movements in the benchmark treasury rate related to forecasted debt issuances. Cintas used interest rate locks, which represent cash flow hedges, to hedge against movements in the treasury rates at the time Cintas issued its senior notes in fiscal 2007, fiscal 2017 and fiscal 2022. For the three months ended August 31, 2024 and 2023, the amortization of the interest rate locks resulted in a decrease to other comprehensive income (loss) of $1.5 million and $1.4 million, respectively. During fiscal 2022 and fiscal 2020, Cintas entered into interest rate lock agreements for forecasted debt issuances. The aggregate notional value of outstanding cash flow hedges was $500.0 million at both August 31, 2024 and May 31, 2024. The fair values of the outstanding interest rate locks, for forecasted debt issuances, are summarized as follows: August 31, 2024 May 31, 2024 Fiscal Year of Issuance (In thousands) Other Other 2022 $ 50,692 $ 56,717 2020 $ 30,773 $ 38,112 The changes in fair value of the interest rate locks are recorded in other comprehensive income (loss), net of tax. These interest rate locks had no impact on net income or cash flows for the three months ended August 31, 2024 or 2023. Cintas has certain covenants related to debt agreements. These covenants limit Cintas' ability to incur certain liens, to engage in sale-leaseback transactions and to merge, consolidate or sell all or substantially all of Cintas' assets. These covenants also require Cintas to maintain certain debt to consolidated earnings before interest, taxes, depreciation and amortization (EBITDA) and interest coverage ratios. Cross-default provisions exist between certain debt instruments. If a default of a significant covenant were to occur, the default could result in an acceleration of the maturity of the indebtedness, impair liquidity and limit the ability to raise future capital. Cintas was in compliance with all of the debt covenants for all periods presented.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In the normal course of business, Cintas provides for uncertain tax positions and the related interest and adjusts its unrecognized tax benefits and accrued interest accordingly. As of August 31, 2024 and May 31, 2024, recorded unrecognized tax benefits were $35.2 million and $32.7 million, respectively, and are included in long-term accrued liabilities on the consolidated condensed balance sheets. The majority of Cintas' operations are in North America. Cintas is required to file U.S. federal income tax returns, as well as state income tax returns in a majority of the domestic states and also in certain Canadian provinces. At times, Cintas is subject to audits in these jurisdictions. The audits, by nature, are sometimes complex and can require several years to resolve. The final resolution of any such tax audit could result in either a reduction in Cintas' accruals or an increase in its income tax provision, either of which could have an impact on the consolidated results of operations in any given period. All U.S. federal income tax returns are closed to audit through fiscal 2020. Cintas is currently in various audits in certain foreign jurisdictions and certain domestic states. The years under foreign and domestic state audits cover fiscal years back to 2018. Based on the status and resolution of the various audits and other potential regulatory developments, it is expected that the balance of unrecognized tax benefits will not materially change for the fiscal year ending May 31, 2025. Cintas’ effective tax rate was 15.8% and 19.2% for the three months ended August 31, 2024 and 2023, respectively. The effective tax rate for both periods was impacted by certain discrete items (primarily the tax accounting for stock-based compensation).

Commitments and Contingencies Disclosure [Abstract]
Litigation and Other Contingencies	Litigation and Other Contingencies Cintas is subject to legal proceedings, insurance receipts, legal settlements and claims arising from the ordinary course of its business, including personal injury, customer contract, environmental and employment claims. In the opinion of management, the aggregate liability, if any, with respect to such ordinary course of business actions will not have a material adverse effect on the consolidated financial position, consolidated results of operations or consolidated cash flows of Cintas. Cintas is party to additional litigation not considered in the ordinary course of business, including the litigation discussed below. The Company is a defendant in a purported class action lawsuit, City of Laurel, Mississippi v. Cintas Corporation No. 2 , filed on March 12, 2021. This is a contract dispute whereby plaintiffs allege that Cintas breached its contracts with participating public agencies and seek, among other things, contract-based damages. In March 2024, an agreement in principle was reached with the plaintiff which would require a one-time monetary payment related to the contract dispute of $45.0 million, which was accrued for and included in accrued liabilities on the consolidated condensed balance sheet at August 31, 2024. The amount reserved for this matter did not have a material impact on the consolidated condensed statements of income for any period presented. The Company will also make certain future investments such as people and technology. These future investments are not expected to be material to the Company. The tentative settlement remains subject to confirmatory discovery and approval of the U.S. District Court for the District of Nevada, however, we do not anticipate any material changes in the amounts reflected in the consolidated condensed financial statements. The Company, the Board of Directors, Scott Farmer (Executive Chairman) and the Investment Policy Committee are defendants in a purported class action, filed on December 13, 2019, pending in the U.S. District Court for the Southern District of Ohio alleging violations of The Employee Retirement Income Security Act of 1974 (ERISA). The lawsuit asserts that the defendants improperly managed the costs of the employee retirement plan, breached their fiduciary duties in failing to investigate and select lower cost alternative funds and failed to monitor and control the employee retirement plan’s recordkeeping costs. In November 2023, an agreement in principle was reached with the plaintiffs, which would require a payment of an immaterial amount that would be covered by the Company's insurance. The settlement received final approval by the U.S. District Court for the Southern District of Ohio in August 2024.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The consolidated condensed financial statements of Cintas Corporation (Cintas, the Company, we, us or our) included herein have been prepared by Cintas, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with United States generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. While we believe that the disclosures are adequately presented, we suggest that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2024 (Annual Report) filed with the SEC on July 25, 2024. See Note 1 entitled Significant Accounting Policies of "Notes to Consolidated Financial Statements" of that Annual Report for a summary of our significant accounting policies. There have been no material changes in the accounting policies followed by Cintas during the current fiscal year. Interim results are subject to variations and are not necessarily indicative of the results of operations for a full fiscal year. In the opinion of management, adjustments (which include only normal recurring adjustments) necessary for a fair statement of the consolidated results of the interim periods shown have been made.
Inventory	Inventories are valued at the lower of cost (first-in, first-out) or net realizable value.The inventory obsolescence reserve is determined by specific identification, as well as an estimate based on Cintas' historical rates of obsolescence. Once a specific inventory item is written down to the lower of cost or net realizable value, a new cost basis has been established, and that inventory item cannot subsequently be marked up.
New Accounting Pronouncements	In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures (ASU 2023-07). ASU 2023-07 requires additional disclosures pertaining to significant expenses and other items of an entity’s reportable operating segments. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 (fiscal 2025). Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-07 on the consolidated condensed financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures (ASU 2023-09), which expands disclosures in an entity’s income tax rate reconciliation table and regarding cash taxes paid both in the U.S. and foreign jurisdictions. ASU 2023-09 will be effective for annual periods beginning after December 15, 2024 (fiscal 2026). The Company is currently evaluating the impact of ASU 2023-09 on the consolidated condensed financial statements. There are no other accounting pronouncements recently issued or newly effective that had, or are expected to have, a material impact on Cintas' consolidated condensed financial statements.
