PAYCHEX, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

February 29, 2024

Note A: Description of Business, Basis of Presentation, and Significant Accounting Policies

Description of business: Paychex, Inc. and its wholly owned subsidiaries (collectively, the “Company” or “Paychex”) is a leading provider of integrated human capital management (“HCM”) solutions for human resources (“HR”), payroll, benefits, and insurance for small- to medium-sized businesses in the United States (“U.S.”) and parts of Europe. The Company also has operations in India. Paychex, a Delaware corporation formed in 1979, reports as one segment.

Basis of presentation: The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q ("Form 10-Q") and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statement presentation. The consolidated financial statements include the consolidated accounts of the Company with all intercompany transactions eliminated. Certain disclosures are reported as zero balances due to rounding. In the opinion of management, the information furnished herein reflects all adjustments (consisting of items of a normal recurring nature) necessary for a fair statement of the results for the interim period. These consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and related Notes to Consolidated Financial Statements presented in the Company’s Annual Report on Form 10-K (“Form 10-K”) for the fiscal year ended May 31, 2023 (“fiscal 2023”). Operating results and cash flows for the nine months ended February 29, 2024 are not necessarily indicative of the results that may be expected for other interim periods or for the fiscal year ending May 31, 2024 (“fiscal 2024”).

Reclassifications: Certain prior year amounts have been reclassified to conform to the current period presentation. These reclassifications had no effect on reported consolidated earnings.

Revision to previously issued financial statements: The consolidated statement of cash flows for the nine months ended February 28, 2023 includes a revision to previously reported amounts related to the presentation of the cash flows associated with short-term receivables purchased from the Company’s clients under non-recourse arrangements. The revision decreased net cash provided by operating activities and increased net cash provided by investing activities by $1.3 million. Management concluded that this revision was not material to the financial statements of any previously filed annual or interim periods. This revision is reflected in this Form 10-Q and will be reflected in future filings.

Restricted cash and restricted cash equivalents: Restricted cash and restricted cash equivalents are recorded at fair value, and consist of cash and cash equivalents, primarily money market securities, included in funds held for clients and cash that is restricted in use to secure commitments for certain workers’ compensation insurance policies.

Accounts receivable, net of allowance for credit losses: Accounts receivable balances are shown on the Consolidated Balance Sheets net of the allowance for credit losses of $22.5 million and $20.5 million as of February 29, 2024 and May 31, 2023, respectively. These balances include trade receivables for services provided to clients and receivables purchased from the Company's clients under non-recourse arrangements. Trade receivables were $215.4 million and $287.0 million as of February 29, 2024 and May 31, 2023, respectively. Purchased receivables, at gross, were $895.7 million and $606.8 million as of February 29, 2024 and May 31, 2023, respectively.

The Company is exposed to credit losses through the sale of services, payment of client obligations, and collection of purchased receivables. To mitigate this credit risk, the Company has multiple programs in place to assess and continuously monitor each client’s ability to pay for these solutions and support. Credit monitoring programs include, but are not limited to, new client credit reviews, establishing appropriate credit limits, monitoring of credit distressed clients, and early electronic wire and collection procedures. The Company also considers contract terms and conditions, client business type or strategy and may require collateralized asset support or prepayment to mitigate credit risk.

Accounts receivable are written off and charged against the allowance for credit losses when the Company has exhausted all collection efforts without success. The Company estimates its credit losses based on historical loss activity adjusted for current economic conditions and reasonable and supportable forecast factors, when applicable. The provision for the allowance for credit losses and accounts written off were not material for the three and nine months ended February 29, 2024 and February 28, 2023. No single client had a material impact on total accounts receivable as of February 29, 2024 and May 31, 2023 or service revenue and results of operations for the three and nine months ended February 29, 2024 and February 28, 2023.

6

Professional Employer Organization (“PEO”) unbilled receivables, net of advance collections: PEO unbilled receivables, including estimated revenues, offset by advance collections from clients, are recorded as PEO unbilled receivables, net of advance collections on the Company’s Consolidated Balance Sheets. As of February 29, 2024 and May 31, 2023, advance collections were $50.2 million and $12.5 million, respectively.

PEO insurance reserves: As part of its PEO solution, the Company offers workers’ compensation insurance and health insurance coverage to clients for the benefit of client employees. Workers’ compensation insurance is primarily provided under fully insured high deductible workers’ compensation insurance policies. Workers’ compensation insurance reserves are established to provide for the estimated costs of paying claims up to per occurrence liability limits. These reserves include estimates of certain expenses associated with processing and settling claims. For fiscal 2024, the Company has an aggregate maximum liability of $1.0 million for claims exceeding $1.0 million, and once met, the maximum individual claims liability is $1.0 million. For fiscal 2023, the Company had an aggregate maximum liability of $2.0 million for claims exceeding $1.0 million, and once met, the maximum individual claims liability is $1.0 million.

With respect to PEO health insurance coverage, the Company offers various health insurance plans that take the form of either fully insured guaranteed cost plans or fully insured insurance arrangements where the Company retains risk. A reserve for insurance arrangements where the Company retains risk is established to provide for the payment of claims in accordance with the Company’s service contract with the carrier. The claims reserve includes estimates for reported losses, plus amounts for those claims incurred but not reported, and estimates of certain expenses associated with processing and settling the claims. The Company’s maximum individual claims liability is $0.5 million under its policies covering both fiscal 2024 and fiscal 2023.

In establishing the PEO workers' compensation insurance reserves, the Company uses an independent actuarial estimate of undiscounted future cash payments that would be made to settle claims. Estimating the ultimate cost of future claims is an uncertain and complex process based upon historical loss experience and accepted actuarial methods and assumptions. These reserves are subject to change due to multiple factors, including economic trends, changes in legal liability law, and damage awards, all of which could materially impact the reserves as reported in the consolidated financial statements. Accordingly, final claim settlements may vary from the present estimates, particularly with workers’ compensation insurance where those payments may not occur until well into the future. The Company regularly reviews the adequacy of its estimated insurance reserves. Adjustments to previously established reserves are reflected in the results of operations for the period in which the adjustment is identified. Such adjustments could be significant, reflecting any combination of new and adverse or favorable trends.

Stock-based compensation costs: The Company has issued stock-based awards to employees and members of its Board of Directors (the “Board”) consisting of stock options, restricted stock units, and restricted stock awards. The Company accounts for all stock-based awards to employees and members of the Board as compensation costs in the consolidated financial statements based on their fair values measured as of the date of grant. These costs are recognized over the requisite service period. Stock-based compensation costs recognized were $14.4 million and $45.1 million for the three and nine months ended February 29, 2024, respectively, as compared with $16.3 million and $46.0 million for the three and nine months ended February 28, 2023, respectively. The methods and assumptions used in the determination of the fair value of stock-based awards are consistent with those described in the Company’s Form 10-K for fiscal 2023.

Recently adopted accounting pronouncements: Effective June 1, 2023, the Company adopted Accounting Standards Update (“ASU”) No. 2021-08 “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers,” which did not have a material impact on its consolidated financial statements.

Recently issued accounting pronouncements: In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. This ASU is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. This ASU is applicable to the Company’s Annual Report on Form 10-K for the fiscal year ending May 31, 2025, and subsequent interim periods, with early application permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU No. 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU updates income tax disclosure requirements primarily by requiring specific categories and greater

disaggregation within the rate reconciliation and disaggregation of income taxes paid by jurisdiction. This ASU is effective for annual periods beginning after December 15, 2024 and is applicable to the Company’s fiscal year beginning June 1, 2025, with early application permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

Other recent authoritative guidance issued by the FASB (including technical corrections to the FASB Accounting Standards Codification), the American Institute of Certified Public Accountants, and the Securities and Exchange Commission (“SEC”) did not or is not expected to have a material impact on the Company’s consolidated financial statements.

Note B: Service Revenue

Service revenue is primarily attributable to fees for providing services to the Company’s clients and is recognized when control of the contracted services is transferred to its clients, in an amount that reflects the consideration it expects to receive in exchange for such services. Insurance Solutions revenue is commissions earned on premiums collected and remitted to insurance carriers. The Company’s contracts generally do not contain specified contract periods and may be terminated by either party with a 30-day notice of termination. Sales and other applicable non-payroll related taxes are excluded from service revenue.

Based upon similar operational and economic characteristics, the Company’s service revenue is disaggregated by Management Solutions and PEO and Insurance Solutions as reported in the Company’s Consolidated Statements of Income and Comprehensive Income. The Company believes these revenue categories depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors.

Management Solutions Revenue

Management Solutions revenue is primarily derived from the Company’s integrated HCM services and HR solutions. Clients can select services on an á la carte basis or as part of various product bundles. The Company’s offerings often leverage the information gathered in its base payroll processing service, allowing it to provide comprehensive services covering the HCM spectrum. Management Solutions revenue is generally recognized over time as services are performed and the client simultaneously receives and controls the benefits from these services.

Revenue earned from delivery service for the distribution of certain client payroll checks and reports is also included in Management Solutions revenue in the Company’s Consolidated Statements of Income and Comprehensive Income. Delivery service revenue is recognized at a point in time following the delivery of payroll checks, reports, quarter-end packages, and tax returns to the Company’s clients.

PEO and Insurance Solutions Revenue

PEO solutions are sold through the Company’s registered and licensed subsidiaries and offer businesses HCM and HR solutions. The Company serves as a co-employer of its clients’ employees, offers health insurance coverage to client employees, and assumes the risks and rewards of workers’ compensation insurance and certain health insurance offerings. PEO Solutions revenue is recognized over time as the services are performed and the client simultaneously receives and controls the benefits from these services. PEO Solutions revenue is reported net of certain pass-through costs billed and incurred, which include payroll wages, payroll taxes, including federal and state unemployment insurance, and health insurance premiums on guaranteed cost benefit plans. For workers’ compensation and health insurance plans where the Company retains risk, revenues and costs are recorded on a gross basis.

PEO pass-through costs netted within the PEO and Insurance Solutions revenue were as follows:

	For the three months ended				For the nine months ended
	February 29,		February 28,		February 29,		February 28,
In millions	2024		2023		2024		2023
Payroll wages and payroll taxes	$	7,317.0	$	6,944.1	$	20,378.5	$	19,615.2
State unemployment insurance (included in payroll wages and payroll taxes)	$	78.0	$	71.4	$	116.3	$	111.2
Guaranteed cost benefit plans	$	165.6	$	157.8	$	499.4	$	494.8

8

Insurance solutions are sold through the Company’s licensed insurance agency, Paychex Insurance Agency, Inc., which provides insurance through a variety of carriers, allowing companies to expand their employee benefit offerings at an affordable cost. Insurance offerings include property and casualty coverage such as workers’ compensation, business-owner policies, commercial auto, cyber security, and health and benefits coverage, including health, dental, vision, and life. Insurance Solutions revenue reflects commissions earned on remitted insurance services premiums billed and is recognized over time as services are performed and the client simultaneously receives and controls the benefits from these services.

Contract Balances

The timing of revenue recognition for Management Solutions and PEO and Insurance Solutions is consistent with the invoicing of clients as they both occur during the respective client payroll period for which the services are provided. Therefore, the Company does not recognize a contract asset or liability resulting from the timing of revenue recognition and invoicing.

Payments received for certain of the Company’s service offerings for set-up fees are considered a material right. Therefore, the Company defers revenue associated with these performance obligations, which exceed one year, and subsequently recognizes them as future services are provided, over approximately three to four years.

Changes in deferred revenue related to material rights that exceed one year were as follows:

	For the three months ended						For the nine months ended
	February 29,			February 28,			February 29,			February 28,
In millions	2024			2023			2024			2023

Balance, end of period	$	73.3		$	58.5		$	73.3		$	58.5

Deferred revenue related to material rights is reported in the deferred revenue and other long-term liabilities line items on the Company’s Consolidated Balance Sheets. As of February 29, 2024, the Company expects to recognize deferred revenue related to these material rights for the remainder of fiscal 2024 and subsequent fiscal years as follows:

In millions	Estimated
Year ending May 31,	recognition of unearned revenue
2024	$	8.4
2025		29.7
Thereafter		35.2
Total recognition of unearned revenue	$	73.3

Assets Recognized from the Costs to Obtain and Fulfill Contracts

The Company recognizes an asset for the incremental costs of obtaining a contract with a client if it is expected that the economic benefit and amortization period will be longer than one year. The Company also recognizes an asset for the costs to fulfill a contract with a client if the costs are specifically identifiable, generate or enhance resources used to satisfy future performance obligations, and are expected to be recovered.

Deferred costs to obtain and fulfill contracts are reported in the prepaid expenses and other current assets and long-term deferred costs line items on the Company’s Consolidated Balance Sheets. Amortization expense related to costs to obtain and fulfill a contract are included in cost of service revenue and selling, general and administrative expenses in the Company’s Consolidated Statements of Income and Comprehensive Income and recognized over the expected economic benefit period.

The Company regularly reviews its deferred costs for potential impairment and did not recognize an impairment loss during the nine months ended February 29, 2024 or February 28, 2023.

Note D: Business Combinations

Effective July 31, 2023, substantially all of the net assets of Alterna Capital Solutions LLC (“Alterna”), were acquired by a wholly owned subsidiary of the Company. Alterna purchases outstanding accounts receivable of their customers under non-recourse arrangements. This acquisition allows the Company to increase and diversify its portfolio of solutions and support serving small- to medium-sized businesses. The acquisition consideration was comprised of a base purchase price of $95.1 million plus immediate settlement of debt totaling $128.9 million, net of $15.7 million in cash and restricted cash acquired. Accounts receivable balances acquired, net of allowance for doubtful accounts, and less amounts due to clients related to funding arrangements, totaled $146.1 million. Management determined that intangible assets related to the client list were $18.9 million to be amortized utilizing an accelerated method of amortization over a weighted average of 8 years. Goodwill in the amount of $46.7 million was recorded as a result of the acquisition, which is tax-deductible. The Company finalized the purchase price allocation for the acquisition of Alterna as of November 30, 2023. The financial results of Alterna are included in the Company’s consolidated financial statements from its respective date of acquisition. This acquisition was not material to the Company’s results of operations, financial position, or cash flows.

The Company regularly reviews its investment portfolios to determine if any investment is impaired due to changes in credit risk or other potential valuation concerns. The Company believes the investments held as of February 29, 2024 that had gross unrealized losses of $164.4 million were not impaired due to credit risk or other valuation concerns, and the Company was not required to record a credit loss or an allowance for credit losses on its AFS securities. The Company believes it is probable that the principal and interest will be collected in accordance with contractual terms and that the unrealized losses on these securities were due to changes in interest rates and were not due to increased credit risk or other valuation concerns. A substantial portion of the securities in an unrealized loss position as of February 29, 2024 and as of May 31, 2023 held an AA rating or better. The Company does not intend to sell these investments until the recovery of their amortized cost basis or maturity and further believes that it is not more-likely-than-not that it will be required to sell these investments prior to that time. The Company’s assessment that an investment is not impaired due to credit risk or other valuation concerns could change in the future due to new developments or changes in the Company’s strategies or assumptions related to any particular investment.

Realized gains and losses on the sale of AFS securities are determined by specific identification of the cost basis of each security. On the Consolidated Statements of Income and Comprehensive Income, realized gains and losses from the funds held for clients portfolio and corporate investments portfolio are included in interest on funds held for clients and other income, net, respectively.

Realized gains and losses from the sale of AFS securities were as follows:

Due after five years		351.8		345.5
Total	$	3,446.9	$	3,285.0

Variable rate demand notes (“VRDNs”), when held by the Company, are primarily categorized as due after five years in the table above as the contractual maturities on these securities are typically 20 to 30 years. Although these securities are issued as long-term securities, they are priced and traded as short-term instruments because of the liquidity provided through the tender feature.

Note G: Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The accounting standards related to fair value measurements include a hierarchy for information and valuations used in measuring fair value that is broken down into three levels based on reliability, as follows:

•Level 1 valuations are based on quoted prices in active markets for identical instruments that the Company can access at the measurement date.

•Level 2 valuations are based on inputs other than quoted prices included in Level 1 that are observable for the instrument, either directly or indirectly, for substantially the full term of the asset or liability including the following:

oquoted prices for similar, but not identical, instruments in active markets;

oquoted prices for identical or similar instruments in markets that are not active;

oinputs other than quoted prices that are observable for the instrument; or

oinputs that are derived principally from or corroborated by observable market data by correlation or other means.

•Level 3 valuations are based on information that is unobservable and significant to the overall fair value measurement.

The carrying values of cash and cash equivalents, restricted cash and restricted cash equivalents, accounts receivable, net of allowance for credit losses, PEO unbilled receivables, net of advance collections, accounts payable and short-term borrowings, when used by the Company, approximate fair value due to the short maturities of these instruments. Marketable securities included in funds held for clients and corporate investments consist primarily of securities classified as AFS and are recorded at fair value on a recurring basis.

In determining the fair value of its assets and liabilities, the Company predominately uses the market approach. Money market securities, which are cash equivalents, are considered Level 1 investments as they are valued based on quoted market prices in active markets. Cash equivalents also include U.S. government agency and treasury securities with original maturities of 90 days or less which are considered Level 2 investments as they are valued based on similar, but not identical, instruments in active markets. AFS securities, including asset-backed securities, corporate bonds, municipal bonds, U.S. government agency securities, and VRDNs, when held by the Company, are included in Level 2 and are valued utilizing inputs obtained from an independent pricing service. To determine the fair value of the Company’s Level 2 AFS securities, the independent pricing service uses a variety of inputs, including benchmark yields, reported trades, non-binding broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, new issue data, and monthly payment information. The Company has not adjusted the prices obtained from the independent pricing service because it believes that they are appropriately valued.

15

Assets included as other are mutual fund investments, consisting of participants’ eligible deferral contributions under the Company’s non-qualified and unfunded deferred compensation plans. The related liability is reported as other long-term liabilities. The mutual funds are considered Level 1 investments as they are valued based on quoted market prices in active markets.

The Company’s long-term borrowings are accounted for on a historical cost basis. As of February 29, 2024 and May 31, 2023, the fair value of long-term borrowings, net of debt issuance costs was $392.1 million and $392.4 million for the Senior Notes, Series A, respectively, and $387.9 million and $390.9 million for the Senior Notes, Series B, respectively.

The Company’s long-term borrowings are not traded in active markets, and as a result, its fair values were estimated using a market approach employing Level 2 valuation inputs, including borrowing rates the Company believes are currently available based on loans with similar terms and maturities.

The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Company 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 fair value measurement at the reporting date.

Note H: Supplemental Information

Property and equipment, net of accumulated depreciation: Depreciation expense was $32.3 million and $94.7 million for the three and nine months ended February 29, 2024, compared to $32.7 million and $95.8 million for the three and nine months ended February 28, 2023.

Goodwill and intangible assets, net of accumulated amortization: Amortization expense relating to intangible assets was $12.5 million and $36.2 million for the three and nine months ended February 29, 2024, compared to $11.5 million and $36.7 million for the three and nine months ended February 28, 2023. Goodwill and intangible assets were recorded during the nine months ended February 29, 2024 related to the acquisition of Alterna. The goodwill related to this acquisition is included in the Purchased Receivable reporting unit for goodwill impairment testing. Refer to Note D for additional information regarding this acquisition and the impact it had on goodwill and intangible assets. The Company did not recognize an impairment loss as it relates to its goodwill or intangible assets during the nine months ended February 29, 2024 or February 28, 2023.

Short-term financing: Outstanding borrowings on the Company’s credit facilities had a weighted-average interest rate of 6.20% and 5.83% as of February 29, 2024 and May 31, 2023, respectively. The unused amount available under these credit facilities as of February 29, 2024 was approximately $2.0 billion.

The credit facilities contain various financial and operational covenants that are usual and customary for such arrangements. The Company was in compliance with all of these covenants as of February 29, 2024.

Letters of credit: The Company had irrevocable standby letters of credit available totaling $170.8 million and $141.7 million as of February 29, 2024 and May 31, 2023, respectively, required to secure commitments for certain insurance policies. The letters of credit expire at various dates between March 03, 2024 and October 09, 2025. No amounts were outstanding on these letters of credit as of, or during the nine months ended February 29, 2024 and February 28, 2023, or as of May 31, 2023.

Long-term debt: There have been no material changes to the Company's long-term debt agreement or balances subsequent to May 31, 2023. The Company’s long-term debt agreement contains customary representations, warranties, affirmative and negative covenants, including financial covenants that are usual and customary for such arrangements. The Company was in compliance with all of these covenants as of February 29, 2024.

Note I: Commitments and Contingencies

Other commitments: The Company had outstanding commitments under existing workers’ compensation insurance agreements and other legally binding contractual arrangements. The Company also enters into various purchase commitments with vendors in the ordinary course of business and had outstanding commitments to purchase capital assets of approximately $6.3 million as of February 29, 2024 and $11.8 million as of May 31, 2023.

In the normal course of business, the Company makes representations and warranties that guarantee the performance of services under service arrangements with clients. Historically, there have been no material losses related to such guarantees. The

16

Company has also entered into indemnification agreements with its officers and directors, which require the Company to defend and, if necessary, indemnify these individuals for certain pending or future claims as they relate to their services provided to the Company.

The Company currently self-insures the deductible portion of various insured exposures under certain corporate employee and PEO employee health and medical benefit plans. The Company’s estimated loss exposure under these insurance arrangements is recorded in other current liabilities on the Consolidated Balance Sheets. Historically, the amounts accrued have not been material and were not material as of February 29, 2024. The Company also maintains insurance, in addition to its purchased primary insurance policies, for gap coverage for employment practices liability, errors and omissions, warranty liability, theft and embezzlement, cyber threats, and acts of terrorism, as well as capacity for deductibles and self-insured retentions through its captive insurance company.

Contingencies: The Company is subject to various claims and legal matters that arise in the normal course of its business. These include disputes or potential disputes related to breach of contract, tort, employment-related claims, tax claims, statutory, and other matters.

The Company’s management currently believes that resolution of any outstanding legal matters will not have a material adverse effect on the Company’s financial position or results of operations. However, legal matters are subject to inherent uncertainties and there exists the possibility that the ultimate resolution of these matters could have a material adverse impact on the Company’s financial position and results of operations in the period in which any such effects are recorded.

Note J: Income Taxes

The Company’s effective income tax rate was 24.4% and 24.3% for the three months ended February 29, 2024 and February 28, 2023, respectively, and 24.1% and 23.8% for the nine months ended February 29, 2024 and February 28, 2023, respectively. All periods were impacted by the recognition of excess tax benefits related to employee stock-based compensation payments.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis of Financial Condition and Results of Operations reviews the operating results of Paychex, Inc. and its wholly owned subsidiaries (“Paychex,” the “Company,” “we,” “our,” or “us”) for the three months ended February 29, 2024 (the “third quarter”), the nine months ended February 29, 2024 (the “nine months”), the respective prior year periods ended February 28, 2023 (the “prior year periods”), and our financial condition as of February 29, 2024. The focus of this review is on the underlying business reasons for material changes and trends affecting our revenue, expenses, net income, and financial condition. This review should be read in conjunction with the February 29, 2024 consolidated financial statements and the related Notes to Consolidated Financial Statements (Unaudited) contained in this Quarterly Report on Form 10-Q (“Form 10-Q”). This review should also be read in conjunction with our Annual Report on Form 10-K (“Form 10-K”) for the year ended May 31, 2023 (“fiscal 2023”). Forward-looking statements in this Form 10-Q are qualified by the cautionary statement included under the next sub-heading, “Cautionary Note Regarding Forward-Looking Statements.”

Cautionary Note Regarding Forward-Looking Statements

Certain written and oral statements made by us may constitute “forward-looking statements” within the meaning of the safe harbor provisions of the United States (“U.S.”) Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by such words and phrases as “expect,” “estimate,” “intend,” “outlook,” “will,” “would,” “project,” “projections,” “strategy,” “anticipate,” “believe,” “could,” “may,” “potential,” “possible,” “purpose,” and other similar words or phrases. Examples of forward-looking statements include, among others, statements we make regarding operating performance, events, or developments that we expect or anticipate will occur in the future, including statements relating to our outlook, revenue growth, earnings, earnings-per-share growth, or similar projections.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations, and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy, and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks, and changes in circumstances that are difficult to predict, many of which are outside our control. Our actual results and financial condition may differ materially from those indicated in the forward-looking statements. Therefore, you should not place undue reliance upon any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following:

•our ability to keep pace with changes in technology or provide timely enhancements to our solutions and support;

•software defects, undetected errors, and development delays for our solutions;

•the possibility of cyberattacks, security vulnerabilities or Internet disruptions, including data security and privacy leaks and data loss and business interruptions;

•the possibility of failure of our business continuity plan during a catastrophic event;

•the failure of third-party service providers to perform their functions;

•the possibility that we may be exposed to additional risks related to our co-employment relationship with our professional employer organization (“PEO”) business;

•changes in health insurance and workers’ compensation insurance rates and underlying claim trends;

•risks related to acquisitions and the integration of the businesses we acquire;

•our clients’ failure to reimburse us for payments made by us on their behalf;

•the effect of changes in government regulations mandating the amount of tax withheld or the timing of remittances;

•our failure to comply with covenants in our debt agreements;

•changes in governmental regulations, laws, and policies;

•our ability to comply with U.S. and foreign laws and regulations;

•our compliance with data privacy laws and regulations;

•our failure to protect our intellectual property rights;

•potential outcomes related to pending or future litigation matters;

•the impact of macroeconomic factors on the U.S. and global economy, and in particular on our small- and medium-sized business clients;

•volatility in the political and economic environment, including inflation and interest rate changes;

•changes in the availability and retention of qualified people; and

•the possible effects of negative publicity on our reputation and the value of our brand.

18

Any of these factors, as well as other factors discussed in our Form 10-K for fiscal 2023 or in our other periodic filings with the Securities and Exchange Commission (“SEC”), could cause our actual results to differ materially from our anticipated results. The information provided in this Form 10-Q is based upon the facts and circumstances known as of the date of this report, and any forward-looking statements made by us in this Form 10-Q speak only as of the date on which they are made. Except as required by law, we undertake no obligation to update these forward-looking statements after the date of filing this Form 10-Q with the SEC to reflect events or circumstances after such date, or to reflect the occurrence of unanticipated events.

Our investor presentation regarding the financial results for the third quarter is available and accessible on our Paychex Investor Relations portal at https://investor.paychex.com. Information available on our website is not a part of, and is not incorporated into, this Form 10-Q. We intend to make future investor presentations available exclusively on our Paychex Investor Relations portal.

n/m – not meaningful

The changes in revenue as compared to the prior year periods were primarily driven by the following factors:

oGrowth in the number of clients served across our suite of HCM solutions;

20

oHigher product penetration, including HR Solutions and retirement; and

oA decline in revenue from ancillary services, primarily due to the winding down of our Employee Retention Tax Credit Service.

oGrowth in the number of average PEO worksite employees;

oIncrease in PEO insurance revenues; and

oHigher revenue from ancillary services for the nine months.

•Interest on funds held for clients: $43.9 million for the third quarter and $108.1 million for the nine months, reflecting increases of 25% and 44%, respectively, primarily due to higher average interest rates.

Total expenses: The following table summarizes the total combined cost of service revenue and selling, general and administrative expenses for the periods below:

	For the three months ended								For the nine months ended
	February 29,		February 28,						February 29,		February 28,

Total expenses	$	789.5	$	769.1		3		%	$	2,290.9	$	2,197.7		4		%

(1) Percentage changes are calculated based on unrounded numbers.

Total expenses increased 3% to $789.5 million for the third quarter and 4% to $2.3 billion for the nine months compared to the prior year periods. Total expenses increased as a result of the following:

•Compensation-related expenses: $461.6 million for the third quarter and $1.4 billion for the nine months, reflecting increases of 2% for the third quarter and 3% for the nine months, driven by increases in average headcount and wage rates.

•PEO direct insurance costs: $119.8 million for the third quarter and $341.5 million for the nine months, reflecting increases of 14% for the third quarter and 9% for the nine months, related to growth in average worksite employees and PEO insurance revenues.

•Other expenses: $163.3 million for the third quarter and $449.0 million for the nine months, reflecting a decrease of 2% for the third quarter and an increase of 5% for the nine months. The increase for the nine months was primarily due to continued investment in technology, sales and marketing.

Operating income: Operating income increased 6% to $649.8 million for the third quarter and 7% to $1.7 billion for the nine months, as a result of revenue growth which outpaced expense increases as previously discussed.

Operating margin (operating income as a percentage of total revenue) was as follows:

	For the three months ended						For the nine months ended
	February 29,			February 28,			February 29,			February 28,
	2024			2023			2024			2023
Operating margin		45.1	%		44.3	%		42.5	%		41.8	%

Other income, net: Other income, net increased $3.9 million to $9.4 million for the third quarter and $29.1 million to income of $33.9 million for the nine months, primarily as a result of higher average interest rates earned on our corporate investments.

Income taxes: Our effective income tax rate was 24.4% for the third quarter and 24.1% for the nine months, compared to 24.3% and 23.8%, for the prior year periods, respectively. All periods were impacted by the recognition of excess tax benefits related to employee stock-based compensation payments.

22

Non-GAAP Financial Measures: Adjusted net income, adjusted diluted earnings per share, and earnings before interest, taxes, depreciation, and amortization (“EBITDA”) are summarized as follows:

	For the three months ended									For the nine months ended
	February 29,			February 28,						February 29,			February 28,
$ in millions	2024			2023			Change			2024			2023			Change

EBITDA	$	694.6		$	655.8			6	%	$	1,823.8		$	1,714.1			6	%

(1) Excess tax benefits related to employee stock-based compensation payments recognized in income taxes. This item is subject to volatility and will vary based on employee decisions on exercising employee stock options and fluctuations in our stock price, neither of which is within the control of management.

(2) The calculation of the impact of non-GAAP adjustments on diluted earnings per share is performed on each line independently. The table may not add down by +/- $0.01 due to rounding.

In addition to reporting net income and diluted earnings per share, which are U.S. GAAP measures, we present adjusted net income, adjusted diluted earnings per share, and EBITDA, which are non-GAAP measures. We believe these additional measures are indicators of our core business operations’ performance period over period. Adjusted net income, adjusted diluted earnings per share, and EBITDA are not calculated through the application of U.S. GAAP and are not required forms of disclosure by the SEC. As such, they should not be considered a substitute for the U.S. GAAP measures of net income and diluted earnings per share, and, therefore, they should not be used in isolation, but in conjunction with the U.S. GAAP measures. The use of any non-GAAP measure may produce results that vary from the U.S. GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies.

LIQUIDITY AND CAPITAL RESOURCES

As of February 29, 2024, our financial position remained strong with cash, restricted cash, and total corporate investments of $1.8 billion. Total short-term and long-term borrowings, net of debt issuance costs, were $817.3 million as of February 29, 2024. Our primary source of cash is our ongoing operations. Cash flow from operations was $1.7 billion for the nine months. Our positive cash flows have allowed us to support our business, pay dividends, and repurchase shares of our common stock. We currently anticipate that cash, restricted cash, and total corporate investments as of February 29, 2024, along with projected operating cash flows and available short-term financing, will support our business operations, capital purchases, share repurchases, and dividend payments for the foreseeable future.

We believe that our investments in an unrealized loss position as of February 29, 2024 were not impaired due to increased credit risk or other valuation concerns, nor has any event occurred subsequent to that date to indicate any change in our assessment.

23

Financing

Short-term financing: We maintain committed and unsecured credit facilities and irrevocable letters of credit as part of our normal and recurring business operations. The purpose of these credit facilities is to meet short-term funding requirements, finance working capital needs, and for general corporate purposes. We typically borrow on an overnight or short-term basis under our credit facilities. Refer to Note L of the Notes to Consolidated Financial Statements contained in Item 8 of our Form 10-K for fiscal 2023 for further discussion of our credit facilities.

Details of our credit facilities as of February 29, 2024 were as follows:

			Maximum			February 29, 2024
			Amount			Outstanding			Available

Total Lines of Credit Outstanding and Available					$		18.8	$		1,981.2

Amounts outstanding under the PNC credit facility as of February 29, 2024 remain outstanding as of the date of this report.

Details of borrowings under each credit facility during the third quarter and the prior year period were as follows:

		For the three months ended February 29, 2024

Short-term borrowings are primarily used for the settlement of client fund obligations, rather than liquidating previously collected client funds that have been invested in AFS securities allocated to our long-term investment portfolio.

Subsequent to February 29, 2024, there were no additional overnight borrowings under our JPM or PNC credit facilities.

We expect to have access to the amounts available under our current credit facilities to meet our ongoing financial needs. However, if we experience reductions in our operating cash flows due to any of the risk factors outlined in, but not limited to, Item 1A in our Form 10-K for fiscal 2023 and other SEC filings, we may need to adjust our capital, operating and other discretionary spending to realign our working capital requirements with the capital resources available to us. Furthermore, if we determine the need for additional short-term liquidity, there is no assurance that such financing, if pursued and obtained, would be adequate or on terms acceptable to us.

24

Letters of credit: As of February 29, 2024, we had irrevocable standby letters of credit available totaling $170.8 million, required to secure commitments for certain insurance policies. The letters of credit expire at various dates between March 03, 2024 and October 09, 2025. No amounts were outstanding on these letters of credit during the third quarter or as of February 29, 2024.

Long-term financing: We have borrowed $800.0 million through the issuance of long-term private placement debt (“Senior Notes”). Certain information related to our Senior Notes are as follows:

	Senior Notes	Senior Notes
	Series A	Series B
Stated interest rate	4.07%	4.25%
Effective interest rate	4.14%	4.31%
Interest rate type	Fixed	Fixed
Interest payment dates	Semi-annual, in arrears	Semi-annual, in arrears
Principal payment dates	March 13, 2026	March 13, 2029
Note type	Unsecured	Unsecured

Refer to Note M of the Notes to Consolidated Financial Statements contained in Item 8 of our Form 10-K for fiscal 2023 for further discussion on our long-term financing.

Other commitments: We had outstanding commitments under existing workers’ compensation insurance agreements and legally binding contractual arrangements. We also entered into various purchase commitments with vendors in the ordinary course of business and had outstanding commitments to purchase approximately $6.3 million of capital assets as of February 29, 2024. In addition, we are involved in three limited partnership agreements to contribute a maximum of $30.0 million to venture capital funds in the financial technology sector. As of February 29, 2024, we have contributed approximately $23.2 million of the total funding commitment.

In the normal course of business, we make representations and warranties that guarantee the performance of services under service arrangements with clients. Historically, there have been no material losses related to such guarantees. We have also entered into indemnification agreements with our officers and directors, which require us to defend and, if necessary, indemnify these individuals for certain pending or future claims as they relate to their services provided to us.

We currently self-insure the deductible portion of various insured exposures under certain corporate employee and PEO employee health and medical benefit plans. Our estimated loss exposure under these insurance arrangements is recorded in other current liabilities on our Consolidated Balance Sheets. Historically, the amounts accrued have not been material and were not material as of February 29, 2024. We also maintain insurance coverage in addition to our purchased primary insurance policies for gap coverage for employment practices liability, errors and omissions, warranty liability, theft and embezzlement, cyber threats, and acts of terrorism; and capacity for deductibles and self-insured retentions through our captive insurance company.

Operating, Investing, and Financing Cash Flow Activities

	For the nine months ended
	February 29,			February 28,
In millions	2024			2023				Change
Net cash provided by operating activities	$	1,676.0		$	1,288.8		$		387.2
Net cash (used in)/provided by investing activities		(117.8	)		363.7				(481.5	)
Net cash provided by/(used in) financing activities		839.8			(218.5	)			1,058.3
Net change in cash, restricted cash, and equivalents	$	2,398.0		$	1,434.0		$		964.0
Cash dividends per common share	$	2.67		$	2.37

The changes in our cash flow for the nine months compared to the prior year period were primarily the result of the following key drivers:

Operating Cash Flow Activities

•Higher net income attributable to the reasons discussed in the “Results of Operations” section of this Item 2;

25

•Net changes in PEO assets and liabilities as a result of the timing of cash collected and the settlement of payroll taxes;

•A net increase in refunds owed to our PEO clients related to tax benefits allowed under the Coronavirus Aid, Relief, and Economic Security Act; and

•Various changes in other assets and liabilities in the normal course of business.

Investing Cash Flow Activities

•Cash used for the acquisition of Alterna Capital Solutions, LLC and settlement of its outstanding debt at closing. Refer to Note D of the Notes to Consolidated Financial Statements for additional discussion of this transaction;

•Lower net sales of AFS securities related to investments in VRDNs, the proceeds from which were reinvested into cash, money market securities or cash equivalents earning more favorable interest rates;

•Increase in net purchases of short-term accounts receivable was primarily due to an increases in our client base, funding to existing client base, and the timing of cash collections on outstanding receivables and cash settlement of the related reserve; and

•Increase in cash spending for upgrades to our internal use software and client lists.

Fluctuations in the net purchases and sales/maturities of AFS securities are also due to timing within the client funds portfolio and market conditions. Amounts will vary based upon the timing of collection from clients and the related remittance to applicable tax or regulatory agencies for payroll tax administration services and to employees of clients utilizing employee payment services.

Discussion of interest rates and related risks is included in the “Market Risk Factors” section of this Item 2.

Financing Cash Flow Activities

•The increase in net cash inflows from changes in client fund obligations is due to the timing of collections and remittances of client funds as February 29, 2024 fell on Thursday, which is a large cash inflow day for client funds. This cash inflow was offset by a higher than usual May 31, 2023 accrual balance due to the cash settlement of semi-weekly payroll taxes being paid a day later than the cycle due to the Memorial Day holiday. February 28, 2023 fell on a Tuesday, which is a lower volume collection or payment day. This inflow was offset by

•Cash used to repurchase 1.5 million shares of our common stock at a weighted average price of $115.37 per share during the nine months. There were no repurchases of our common shares during the fiscal 2023 period. All repurchased shares were retired upon acquisition; and

•Dividends paid increased compared to the prior year period due to an increase in our cumulative dividend from $2.37 per share to $2.67 per share. The payment of future dividends is dependent on our future earnings and cash flow and is subject to the discretion of our Board of Directors (the "Board").

The client fund obligations liability will vary based on the timing of collecting client funds and the related required remittance of funds to applicable tax or regulatory agencies for payroll tax administration services and to employees of clients utilizing employee payment services. Collections from clients are typically remitted from one to 30 days after receipt, with some items extending to 90 days.

MARKET RISK FACTORS

Changes in interest rates and interest rate risk: Funds held for clients are primarily comprised of short-term funds and AFS securities. Corporate investments are primarily comprised of AFS securities. As a result of our investing activities, we are exposed to changes in interest rates that may materially affect our results of operations and financial position. Changes in interest rates will impact the earnings potential of future investments and will cause fluctuations in the fair value of our long-term AFS securities. We follow an investment strategy of protecting principal and optimizing liquidity. A substantial portion of our portfolios is invested in high credit quality securities with ratings of AA or higher, and A-1/P-1 ratings on short-term securities. We invest predominantly in corporate bonds; municipal bonds; U.S. government agency securities; and VRDNs when available in the market. We limit the amounts that can be invested in any single issuer and invest primarily in short- to intermediate-term instruments whose fair value is less sensitive to interest rate changes. We manage the AFS securities to a benchmark duration of two and one-half to three and three-quarters years.

26

During the nine months ended February 29, 2024, our primary short-term investment vehicles were U.S. government agency discount notes and bank demand deposit accounts. We have no exposure to high-risk or non-liquid investments. We have insignificant exposure to European investments. We have not and do not utilize derivative financial instruments to manage our interest rate risk.

During the nine months ended February 29, 2024, the average interest rate earned on our combined funds held for clients and corporate cash equivalents and investment portfolios was 3.8% compared to 2.4% for the prior year period. When interest rates are falling, the full impact of lower interest rates will not immediately be reflected in net income due to the interaction of short- and long-term interest rate changes. During a falling interest rate environment, earnings will decrease from our short-term investments, and over time, decrease from our longer-term AFS securities. Earnings from AFS securities, which as of February 29, 2024 had an average duration of 2.9 years, would not reflect decreases in interest rates until the investments are sold or mature and the proceeds are reinvested at lower rates.

The amortized cost and fair value of AFS securities that had stated maturities as of February 29, 2024 are shown below by expected maturity.

	February 29, 2024
	Amortized		Fair
In millions	cost		value
Maturity date:
Due in one year or less	$	157.0	$	154.5
Due after one year through three years		1,262.6		1,197.0
Due after three years through five years		1,675.5		1,588.0
Due after five years		351.8		345.5
Total	$	3,446.9	$	3,285.0

VRDNs, when held by us, are primarily categorized as due after five years in the table above as the contractual maturities on these securities are typically 20 to 30 years. Although these securities are issued as long-term securities, they are priced and traded as short-term instruments because of the liquidity provided through the tender feature.

As of February 29, 2024, the Federal Funds rate was in the range of 5.25% to 5.50%. There continues to be uncertainty in the changing market and economic conditions, including the possibility of additional measures that could be taken by the Federal Reserve and other government agencies, related to concerns over inflation risk and the failure of financial institutions. We will continue to monitor the market and economic conditions.

Calculating the future effects of changing interest rates involves many factors. These factors include, but are not limited to:

•governmental action to address inflation and/or intervene to support financial markets;

•daily interest rate changes;

•seasonal variations in investment balances;

•actual duration of short-term and AFS securities;

•the proportion of taxable and tax-exempt investments;

•changes in tax-exempt municipal rates versus taxable investment rates, which are not synchronized or simultaneous; and

•financial market volatility and the resulting effect on benchmark and other indexing interest rates.

Subject to these factors and under normal financial market conditions, a 25-basis-point change in taxable interest rates generally affects our tax-exempt interest rates by approximately 19 basis points. Under normal financial market conditions, the impact to earnings from a 25-basis-point change in short-term interest rates would be approximately $4.5 million to $5.0 million, after taxes, for a twelve-month period. Such a basis point change may or may not be tied to changes in the Federal Funds rate.

Our total investment portfolio (funds held for clients and corporate cash equivalents and investments) is expected to average approximately $6.0 billion for the year ending May 31, 2024. Our anticipated allocation is approximately 40% invested in short-term securities and VRDNs with an average duration of less than 30 days and 60% invested in AFS securities, with an average duration of two and one-half to three and three-quarters years.

27

The combined funds held for clients and corporate AFS securities reflected net unrealized losses of $161.9 million as of February 29, 2024 and $175.3 million as of May 31, 2023. During the nine months ended February 29, 2024, the net unrealized loss on our investment portfolios ranged from a loss of $125.7 million to a loss of $259.6 million. These fluctuations were driven by changes in market rates of interest. The net unrealized loss on our investment portfolio was approximately $149.4 million as of March 28, 2024.

As of February 29, 2024 and May 31, 2023, we had $3.3 billion and $3.6 billion, respectively, invested in AFS securities at fair value. The weighted-average yield-to-maturity was 3.0% as of February 29, 2024 and 2.9 % as of May 31, 2023. The weighted-average yield-to-maturity excludes AFS securities tied to short-term interest rates, such as VRDNs, when held. Assuming a hypothetical decrease in longer-term interest rates of 25 basis points, the resulting potential increase in fair value for our portfolio of AFS securities as of February 29, 2024, would be in a range of approximately $20.0 million to $25.0 million. Conversely, a corresponding increase in interest rates would result in a comparable decrease in fair value. This hypothetical decrease or increase in the fair value of the portfolio would be recorded as an adjustment to the portfolio’s recorded value, with an offsetting amount recorded in stockholders’ equity. These fluctuations in fair value would have no related or immediate impact on our results of operations unless any declines in fair value are due to credit related concerns and an impairment loss is recognized.

We are also exposed to interest rate risk through the use of our credit facilities as outlined in the Liquidity and Capital Resources section of this Form 10-Q. If interest rates were to increase, or we increase the frequency or amounts borrowed under these credit facilities, we could experience additional interest expense and a corresponding decrease in earnings.

Credit risk: We are exposed to credit risk in connection with our investments in AFS securities through the possible inability of the borrowers to meet the terms of their bonds. We regularly review our investment portfolios to determine if any investment is impaired due to increased credit risk or other valuation concerns and we believe that the investments we held as of February 29, 2024 were not impaired as a result of the previously discussed reasons. While $3.1 billion of our AFS securities had fair values that were below amortized cost, we believe that it is probable that the principal and interest will be collected in accordance with the contractual terms, and that the gross unrealized losses of $164.4 million were due to changes in interest rates and were not due to increased credit risk or other valuation concerns. A substantial portion of the AFS securities in an unrealized loss position as of February 29, 2024 and May 31, 2023 had an AA rating or better. We do not intend to sell these investments until the recovery of their amortized cost basis or maturity, and further believe that it is not more-likely-than-not that we will be required to sell these investments prior to that time. Our assessment that an investment is not impaired due to increased credit risk or other valuation concerns could change in the future due to new developments, including changes in our strategies or assumptions related to any particular investment.

We have some credit risk exposure relating to our purchase of client accounts receivable under non-recourse arrangements. There is also credit risk exposure relating to our trade accounts receivable. This credit risk exposure is diversified amongst multiple client arrangements and all such arrangements are regularly reviewed for potential write-off. No single client was material in respect to total accounts receivable, service revenue, or results of operations as of February 29, 2024.

Market risk: We have an ongoing monitoring system for financial institutions we conduct business with and maintain cash balances at large well-capitalized (as defined by their regulators) financial institutions. We continue to closely monitor this situation and take appropriate measures, when necessary, to minimize potential risk exposure to our client’s and our cash and investment balances.

CRITICAL ACCOUNTING POLICIES

Our critical accounting policies are described in Item 7 of our Form 10-K for fiscal 2023, filed with the SEC on July 14, 2023. On an ongoing basis, we evaluate the critical accounting policies used to prepare our consolidated financial statements, including, but not limited to, those related to:

•revenue recognition;

•assets recognized from the costs to obtain and fulfill contracts;

•PEO insurance reserves;

•goodwill and other intangible assets;

•impairment of long-lived assets;

•stock-based compensation costs; and

28

•income taxes.

There have been no material changes in these aforementioned critical accounting policies.

The information called for by this item is provided under the caption “Market Risk Factors” under Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations and is incorporated herein by reference.

Item 4. Controls and Procedures

Disclosure Controls and Procedures: Disclosure controls and procedures are designed with the objective of ensuring that information required to be disclosed in the Company’s reports filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), such as this report, is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures are also designed with the objective of ensuring that such information is accumulated and communicated to the Company’s management, including the Company’s principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures: As of the end of the period covered by this report, the Company carried out an evaluation, under the supervision and with the participation of the Company’s principal executive officer and principal financial officer, of the effectiveness of disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on such evaluation, the Company’s principal executive officer and principal financial officer have concluded that as of February 29, 2024, the end of the period covered by this report, our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Control over Financial Reporting: The Company also carried out an evaluation of the internal control over financial reporting to determine whether any changes occurred during the fiscal quarter ended February 29, 2024. Based on such evaluation, there have been no changes in the Company’s internal control over financial reporting that occurred during the Company’s most recently completed fiscal quarter ended February 29, 2024, that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Description of Business, Basis of Presentation, and Significant Accounting Policies

Accounting Policies [Abstract]

Description of Business, Basis of Presentation, and Significant Accounting Policies

Note A: Description of Business, Basis of Presentation, and Significant Accounting Policies

Description of business: Paychex, Inc. and its wholly owned subsidiaries (collectively, the “Company” or “Paychex”) is a leading provider of integrated human capital management (“HCM”) solutions for human resources (“HR”), payroll, benefits, and insurance for small- to medium-sized businesses in the United States (“U.S.”) and parts of Europe. The Company also has operations in India. Paychex, a Delaware corporation formed in 1979, reports as one segment.

Basis of presentation: The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q ("Form 10-Q") and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statement presentation. The consolidated financial statements include the consolidated accounts of the Company with all intercompany transactions eliminated. Certain disclosures are reported as zero balances due to rounding. In the opinion of management, the information furnished herein reflects all adjustments (consisting of items of a normal recurring nature) necessary for a fair statement of the results for the interim period. These consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and related Notes to Consolidated Financial Statements presented in the Company’s Annual Report on Form 10-K (“Form 10-K”) for the fiscal year ended May 31, 2023 (“fiscal 2023”). Operating results and cash flows for the nine months ended February 29, 2024 are not necessarily indicative of the results that may be expected for other interim periods or for the fiscal year ending May 31, 2024 (“fiscal 2024”).

Reclassifications: Certain prior year amounts have been reclassified to conform to the current period presentation. These reclassifications had no effect on reported consolidated earnings.

Revision to previously issued financial statements: The consolidated statement of cash flows for the nine months ended February 28, 2023 includes a revision to previously reported amounts related to the presentation of the cash flows associated with short-term receivables purchased from the Company’s clients under non-recourse arrangements. The revision decreased net cash provided by operating activities and increased net cash provided by investing activities by $1.3 million. Management concluded that this revision was not material to the financial statements of any previously filed annual or interim periods. This revision is reflected in this Form 10-Q and will be reflected in future filings.

Restricted cash and restricted cash equivalents: Restricted cash and restricted cash equivalents are recorded at fair value, and consist of cash and cash equivalents, primarily money market securities, included in funds held for clients and cash that is restricted in use to secure commitments for certain workers’ compensation insurance policies.

Accounts receivable, net of allowance for credit losses: Accounts receivable balances are shown on the Consolidated Balance Sheets net of the allowance for credit losses of $22.5 million and $20.5 million as of February 29, 2024 and May 31, 2023, respectively. These balances include trade receivables for services provided to clients and receivables purchased from the Company's clients under non-recourse arrangements. Trade receivables were $215.4 million and $287.0 million as of February 29, 2024 and May 31, 2023, respectively. Purchased receivables, at gross, were $895.7 million and $606.8 million as of February 29, 2024 and May 31, 2023, respectively.

The Company is exposed to credit losses through the sale of services, payment of client obligations, and collection of purchased receivables. To mitigate this credit risk, the Company has multiple programs in place to assess and continuously monitor each client’s ability to pay for these solutions and support. Credit monitoring programs include, but are not limited to, new client credit reviews, establishing appropriate credit limits, monitoring of credit distressed clients, and early electronic wire and collection procedures. The Company also considers contract terms and conditions, client business type or strategy and may require collateralized asset support or prepayment to mitigate credit risk.

Accounts receivable are written off and charged against the allowance for credit losses when the Company has exhausted all collection efforts without success. The Company estimates its credit losses based on historical loss activity adjusted for current economic conditions and reasonable and supportable forecast factors, when applicable. The provision for the allowance for credit losses and accounts written off were not material for the three and nine months ended February 29, 2024 and February 28, 2023. No single client had a material impact on total accounts receivable as of February 29, 2024 and May 31, 2023 or service revenue and results of operations for the three and nine months ended February 29, 2024 and February 28, 2023.

Professional Employer Organization (“PEO”) unbilled receivables, net of advance collections: PEO unbilled receivables, including estimated revenues, offset by advance collections from clients, are recorded as PEO unbilled receivables, net of advance collections on the Company’s Consolidated Balance Sheets. As of February 29, 2024 and May 31, 2023, advance collections were $50.2 million and $12.5 million, respectively.

PEO insurance reserves: As part of its PEO solution, the Company offers workers’ compensation insurance and health insurance coverage to clients for the benefit of client employees. Workers’ compensation insurance is primarily provided under fully insured high deductible workers’ compensation insurance policies. Workers’ compensation insurance reserves are established to provide for the estimated costs of paying claims up to per occurrence liability limits. These reserves include estimates of certain expenses associated with processing and settling claims. For fiscal 2024, the Company has an aggregate maximum liability of $1.0 million for claims exceeding $1.0 million, and once met, the maximum individual claims liability is $1.0 million. For fiscal 2023, the Company had an aggregate maximum liability of $2.0 million for claims exceeding $1.0 million, and once met, the maximum individual claims liability is $1.0 million.

With respect to PEO health insurance coverage, the Company offers various health insurance plans that take the form of either fully insured guaranteed cost plans or fully insured insurance arrangements where the Company retains risk. A reserve for insurance arrangements where the Company retains risk is established to provide for the payment of claims in accordance with the Company’s service contract with the carrier. The claims reserve includes estimates for reported losses, plus amounts for those claims incurred but not reported, and estimates of certain expenses associated with processing and settling the claims. The Company’s maximum individual claims liability is $0.5 million under its policies covering both fiscal 2024 and fiscal 2023.

In establishing the PEO workers' compensation insurance reserves, the Company uses an independent actuarial estimate of undiscounted future cash payments that would be made to settle claims. Estimating the ultimate cost of future claims is an uncertain and complex process based upon historical loss experience and accepted actuarial methods and assumptions. These reserves are subject to change due to multiple factors, including economic trends, changes in legal liability law, and damage awards, all of which could materially impact the reserves as reported in the consolidated financial statements. Accordingly, final claim settlements may vary from the present estimates, particularly with workers’ compensation insurance where those payments may not occur until well into the future. The Company regularly reviews the adequacy of its estimated insurance reserves. Adjustments to previously established reserves are reflected in the results of operations for the period in which the adjustment is identified. Such adjustments could be significant, reflecting any combination of new and adverse or favorable trends.

Stock-based compensation costs: The Company has issued stock-based awards to employees and members of its Board of Directors (the “Board”) consisting of stock options, restricted stock units, and restricted stock awards. The Company accounts for all stock-based awards to employees and members of the Board as compensation costs in the consolidated financial statements based on their fair values measured as of the date of grant. These costs are recognized over the requisite service period. Stock-based compensation costs recognized were $14.4 million and $45.1 million for the three and nine months ended February 29, 2024, respectively, as compared with $16.3 million and $46.0 million for the three and nine months ended February 28, 2023, respectively. The methods and assumptions used in the determination of the fair value of stock-based awards are consistent with those described in the Company’s Form 10-K for fiscal 2023.

Recently adopted accounting pronouncements: Effective June 1, 2023, the Company adopted Accounting Standards Update (“ASU”) No. 2021-08 “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers,” which did not have a material impact on its consolidated financial statements.

Recently issued accounting pronouncements: In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. This ASU is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. This ASU is applicable to the Company’s Annual Report on Form 10-K for the fiscal year ending May 31, 2025, and subsequent interim periods, with early application permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU No. 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU updates income tax disclosure requirements primarily by requiring specific categories and greater

disaggregation within the rate reconciliation and disaggregation of income taxes paid by jurisdiction. This ASU is effective for annual periods beginning after December 15, 2024 and is applicable to the Company’s fiscal year beginning June 1, 2025, with early application permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

Other recent authoritative guidance issued by the FASB (including technical corrections to the FASB Accounting Standards Codification), the American Institute of Certified Public Accountants, and the Securities and Exchange Commission (“SEC”) did not or is not expected to have a material impact on the Company’s consolidated financial statements.

Service Revenue

Revenue from Contract with Customer [Abstract]

Service Revenue

Note B: Service Revenue

Service revenue is primarily attributable to fees for providing services to the Company’s clients and is recognized when control of the contracted services is transferred to its clients, in an amount that reflects the consideration it expects to receive in exchange for such services. Insurance Solutions revenue is commissions earned on premiums collected and remitted to insurance carriers. The Company’s contracts generally do not contain specified contract periods and may be terminated by either party with a 30-day notice of termination. Sales and other applicable non-payroll related taxes are excluded from service revenue.

Based upon similar operational and economic characteristics, the Company’s service revenue is disaggregated by Management Solutions and PEO and Insurance Solutions as reported in the Company’s Consolidated Statements of Income and Comprehensive Income. The Company believes these revenue categories depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors.

Management Solutions Revenue

Management Solutions revenue is primarily derived from the Company’s integrated HCM services and HR solutions. Clients can select services on an á la carte basis or as part of various product bundles. The Company’s offerings often leverage the information gathered in its base payroll processing service, allowing it to provide comprehensive services covering the HCM spectrum. Management Solutions revenue is generally recognized over time as services are performed and the client simultaneously receives and controls the benefits from these services.

Revenue earned from delivery service for the distribution of certain client payroll checks and reports is also included in Management Solutions revenue in the Company’s Consolidated Statements of Income and Comprehensive Income. Delivery service revenue is recognized at a point in time following the delivery of payroll checks, reports, quarter-end packages, and tax returns to the Company’s clients.

PEO and Insurance Solutions Revenue

PEO solutions are sold through the Company’s registered and licensed subsidiaries and offer businesses HCM and HR solutions. The Company serves as a co-employer of its clients’ employees, offers health insurance coverage to client employees, and assumes the risks and rewards of workers’ compensation insurance and certain health insurance offerings. PEO Solutions revenue is recognized over time as the services are performed and the client simultaneously receives and controls the benefits from these services. PEO Solutions revenue is reported net of certain pass-through costs billed and incurred, which include payroll wages, payroll taxes, including federal and state unemployment insurance, and health insurance premiums on guaranteed cost benefit plans. For workers’ compensation and health insurance plans where the Company retains risk, revenues and costs are recorded on a gross basis.

PEO pass-through costs netted within the PEO and Insurance Solutions revenue were as follows:

	For the three months ended				For the nine months ended
	February 29,		February 28,		February 29,		February 28,
In millions	2024		2023		2024		2023
Payroll wages and payroll taxes	$	7,317.0	$	6,944.1	$	20,378.5	$	19,615.2
State unemployment insurance (included in payroll wages and payroll taxes)	$	78.0	$	71.4	$	116.3	$	111.2
Guaranteed cost benefit plans	$	165.6	$	157.8	$	499.4	$	494.8

Insurance solutions are sold through the Company’s licensed insurance agency, Paychex Insurance Agency, Inc., which provides insurance through a variety of carriers, allowing companies to expand their employee benefit offerings at an affordable cost. Insurance offerings include property and casualty coverage such as workers’ compensation, business-owner policies, commercial auto, cyber security, and health and benefits coverage, including health, dental, vision, and life. Insurance Solutions revenue reflects commissions earned on remitted insurance services premiums billed and is recognized over time as services are performed and the client simultaneously receives and controls the benefits from these services.

Contract Balances

The timing of revenue recognition for Management Solutions and PEO and Insurance Solutions is consistent with the invoicing of clients as they both occur during the respective client payroll period for which the services are provided. Therefore, the Company does not recognize a contract asset or liability resulting from the timing of revenue recognition and invoicing.

Payments received for certain of the Company’s service offerings for set-up fees are considered a material right. Therefore, the Company defers revenue associated with these performance obligations, which exceed one year, and subsequently recognizes them as future services are provided, over approximately three to four years.

Changes in deferred revenue related to material rights that exceed one year were as follows:

	For the three months ended						For the nine months ended
	February 29,			February 28,			February 29,			February 28,
In millions	2024			2023			2024			2023

Balance, end of period	$	73.3		$	58.5		$	73.3		$	58.5

Deferred revenue related to material rights is reported in the deferred revenue and other long-term liabilities line items on the Company’s Consolidated Balance Sheets. As of February 29, 2024, the Company expects to recognize deferred revenue related to these material rights for the remainder of fiscal 2024 and subsequent fiscal years as follows:

In millions	Estimated
Year ending May 31,	recognition of unearned revenue
2024	$	8.4
2025		29.7
Thereafter		35.2
Total recognition of unearned revenue	$	73.3

Assets Recognized from the Costs to Obtain and Fulfill Contracts

The Company recognizes an asset for the incremental costs of obtaining a contract with a client if it is expected that the economic benefit and amortization period will be longer than one year. The Company also recognizes an asset for the costs to fulfill a contract with a client if the costs are specifically identifiable, generate or enhance resources used to satisfy future performance obligations, and are expected to be recovered.

Deferred costs to obtain and fulfill contracts are reported in the prepaid expenses and other current assets and long-term deferred costs line items on the Company’s Consolidated Balance Sheets. Amortization expense related to costs to obtain and fulfill a contract are included in cost of service revenue and selling, general and administrative expenses in the Company’s Consolidated Statements of Income and Comprehensive Income and recognized over the expected economic benefit period.

The Company regularly reviews its deferred costs for potential impairment and did not recognize an impairment loss during the nine months ended February 29, 2024 or February 28, 2023.

Changes in deferred costs to obtain and fulfill contracts were as follows:

The Company regularly reviews its investment portfolios to determine if any investment is impaired due to changes in credit risk or other potential valuation concerns. The Company believes the investments held as of February 29, 2024 that had gross unrealized losses of $164.4 million were not impaired due to credit risk or other valuation concerns, and the Company was not required to record a credit loss or an allowance for credit losses on its AFS securities. The Company believes it is probable that the principal and interest will be collected in accordance with contractual terms and that the unrealized losses on these securities were due to changes in interest rates and were not due to increased credit risk or other valuation concerns. A substantial portion of the securities in an unrealized loss position as of February 29, 2024 and as of May 31, 2023 held an AA rating or better. The Company does not intend to sell these investments until the recovery of their amortized cost basis or maturity and further believes that it is not more-likely-than-not that it will be required to sell these investments prior to that time. The Company’s assessment that an investment is not impaired due to credit risk or other valuation concerns could change in the future due to new developments or changes in the Company’s strategies or assumptions related to any particular investment.

Realized gains and losses on the sale of AFS securities are determined by specific identification of the cost basis of each security. On the Consolidated Statements of Income and Comprehensive Income, realized gains and losses from the funds held for clients portfolio and corporate investments portfolio are included in interest on funds held for clients and other income, net, respectively.

Realized gains and losses from the sale of AFS securities were as follows:

	For the three months ended				For the nine months ended

Due after five years		351.8		345.5
Total	$	3,446.9	$	3,285.0

Variable rate demand notes (“VRDNs”), when held by the Company, are primarily categorized as due after five years in the table above as the contractual maturities on these securities are typically 20 to 30 years. Although these securities are issued as long-term securities, they are priced and traded as short-term instruments because of the liquidity provided through the tender feature.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note G: Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The accounting standards related to fair value measurements include a hierarchy for information and valuations used in measuring fair value that is broken down into three levels based on reliability, as follows:

•Level 1 valuations are based on quoted prices in active markets for identical instruments that the Company can access at the measurement date.

•Level 2 valuations are based on inputs other than quoted prices included in Level 1 that are observable for the instrument, either directly or indirectly, for substantially the full term of the asset or liability including the following:

oquoted prices for similar, but not identical, instruments in active markets;

oquoted prices for identical or similar instruments in markets that are not active;

oinputs other than quoted prices that are observable for the instrument; or

oinputs that are derived principally from or corroborated by observable market data by correlation or other means.

•Level 3 valuations are based on information that is unobservable and significant to the overall fair value measurement.

The carrying values of cash and cash equivalents, restricted cash and restricted cash equivalents, accounts receivable, net of allowance for credit losses, PEO unbilled receivables, net of advance collections, accounts payable and short-term borrowings, when used by the Company, approximate fair value due to the short maturities of these instruments. Marketable securities included in funds held for clients and corporate investments consist primarily of securities classified as AFS and are recorded at fair value on a recurring basis.

The Company’s financial assets and liabilities measured at fair value on a recurring basis were as follows:

In determining the fair value of its assets and liabilities, the Company predominately uses the market approach. Money market securities, which are cash equivalents, are considered Level 1 investments as they are valued based on quoted market prices in active markets. Cash equivalents also include U.S. government agency and treasury securities with original maturities of 90 days or less which are considered Level 2 investments as they are valued based on similar, but not identical, instruments in active markets. AFS securities, including asset-backed securities, corporate bonds, municipal bonds, U.S. government agency securities, and VRDNs, when held by the Company, are included in Level 2 and are valued utilizing inputs obtained from an independent pricing service. To determine the fair value of the Company’s Level 2 AFS securities, the independent pricing service uses a variety of inputs, including benchmark yields, reported trades, non-binding broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, new issue data, and monthly payment information. The Company has not adjusted the prices obtained from the independent pricing service because it believes that they are appropriately valued.

Assets included as other are mutual fund investments, consisting of participants’ eligible deferral contributions under the Company’s non-qualified and unfunded deferred compensation plans. The related liability is reported as other long-term liabilities. The mutual funds are considered Level 1 investments as they are valued based on quoted market prices in active markets.

The Company’s long-term borrowings are accounted for on a historical cost basis. As of February 29, 2024 and May 31, 2023, the fair value of long-term borrowings, net of debt issuance costs was $392.1 million and $392.4 million for the Senior Notes, Series A, respectively, and $387.9 million and $390.9 million for the Senior Notes, Series B, respectively.

The Company’s long-term borrowings are not traded in active markets, and as a result, its fair values were estimated using a market approach employing Level 2 valuation inputs, including borrowing rates the Company believes are currently available based on loans with similar terms and maturities.

The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Company 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 fair value measurement at the reporting date.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note I: Commitments and Contingencies

Other commitments: The Company had outstanding commitments under existing workers’ compensation insurance agreements and other legally binding contractual arrangements. The Company also enters into various purchase commitments with vendors in the ordinary course of business and had outstanding commitments to purchase capital assets of approximately $6.3 million as of February 29, 2024 and $11.8 million as of May 31, 2023.

In the normal course of business, the Company makes representations and warranties that guarantee the performance of services under service arrangements with clients. Historically, there have been no material losses related to such guarantees. The

Company has also entered into indemnification agreements with its officers and directors, which require the Company to defend and, if necessary, indemnify these individuals for certain pending or future claims as they relate to their services provided to the Company.

The Company currently self-insures the deductible portion of various insured exposures under certain corporate employee and PEO employee health and medical benefit plans. The Company’s estimated loss exposure under these insurance arrangements is recorded in other current liabilities on the Consolidated Balance Sheets. Historically, the amounts accrued have not been material and were not material as of February 29, 2024. The Company also maintains insurance, in addition to its purchased primary insurance policies, for gap coverage for employment practices liability, errors and omissions, warranty liability, theft and embezzlement, cyber threats, and acts of terrorism, as well as capacity for deductibles and self-insured retentions through its captive insurance company.

Contingencies: The Company is subject to various claims and legal matters that arise in the normal course of its business. These include disputes or potential disputes related to breach of contract, tort, employment-related claims, tax claims, statutory, and other matters.

The Company’s management currently believes that resolution of any outstanding legal matters will not have a material adverse effect on the Company’s financial position or results of operations. However, legal matters are subject to inherent uncertainties and there exists the possibility that the ultimate resolution of these matters could have a material adverse impact on the Company’s financial position and results of operations in the period in which any such effects are recorded.

Accounting Policies [Abstract]

Description of Business

Description of business: Paychex, Inc. and its wholly owned subsidiaries (collectively, the “Company” or “Paychex”) is a leading provider of integrated human capital management (“HCM”) solutions for human resources (“HR”), payroll, benefits, and insurance for small- to medium-sized businesses in the United States (“U.S.”) and parts of Europe. The Company also has operations in India. Paychex, a Delaware corporation formed in 1979, reports as one segment.

Basis of Presentation

Basis of presentation: The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q ("Form 10-Q") and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statement presentation. The consolidated financial statements include the consolidated accounts of the Company with all intercompany transactions eliminated. Certain disclosures are reported as zero balances due to rounding. In the opinion of management, the information furnished herein reflects all adjustments (consisting of items of a normal recurring nature) necessary for a fair statement of the results for the interim period. These consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and related Notes to Consolidated Financial Statements presented in the Company’s Annual Report on Form 10-K (“Form 10-K”) for the fiscal year ended May 31, 2023 (“fiscal 2023”). Operating results and cash flows for the nine months ended February 29, 2024 are not necessarily indicative of the results that may be expected for other interim periods or for the fiscal year ending May 31, 2024 (“fiscal 2024”).

Reclassifications

Reclassifications: Certain prior year amounts have been reclassified to conform to the current period presentation. These reclassifications had no effect on reported consolidated earnings.

Revision to previously issued financial statements

Revision to previously issued financial statements: The consolidated statement of cash flows for the nine months ended February 28, 2023 includes a revision to previously reported amounts related to the presentation of the cash flows associated with short-term receivables purchased from the Company’s clients under non-recourse arrangements. The revision decreased net cash provided by operating activities and increased net cash provided by investing activities by $1.3 million. Management concluded that this revision was not material to the financial statements of any previously filed annual or interim periods. This revision is reflected in this Form 10-Q and will be reflected in future filings.

Restricted Cash and Restricted Cash Equivalents

Restricted cash and restricted cash equivalents: Restricted cash and restricted cash equivalents are recorded at fair value, and consist of cash and cash equivalents, primarily money market securities, included in funds held for clients and cash that is restricted in use to secure commitments for certain workers’ compensation insurance policies.

Accounts Receivable, Net of Allowance for Credit Losses

Accounts receivable, net of allowance for credit losses: Accounts receivable balances are shown on the Consolidated Balance Sheets net of the allowance for credit losses of $22.5 million and $20.5 million as of February 29, 2024 and May 31, 2023, respectively. These balances include trade receivables for services provided to clients and receivables purchased from the Company's clients under non-recourse arrangements. Trade receivables were $215.4 million and $287.0 million as of February 29, 2024 and May 31, 2023, respectively. Purchased receivables, at gross, were $895.7 million and $606.8 million as of February 29, 2024 and May 31, 2023, respectively.

The Company is exposed to credit losses through the sale of services, payment of client obligations, and collection of purchased receivables. To mitigate this credit risk, the Company has multiple programs in place to assess and continuously monitor each client’s ability to pay for these solutions and support. Credit monitoring programs include, but are not limited to, new client credit reviews, establishing appropriate credit limits, monitoring of credit distressed clients, and early electronic wire and collection procedures. The Company also considers contract terms and conditions, client business type or strategy and may require collateralized asset support or prepayment to mitigate credit risk.

Accounts receivable are written off and charged against the allowance for credit losses when the Company has exhausted all collection efforts without success. The Company estimates its credit losses based on historical loss activity adjusted for current economic conditions and reasonable and supportable forecast factors, when applicable. The provision for the allowance for credit losses and accounts written off were not material for the three and nine months ended February 29, 2024 and February 28, 2023. No single client had a material impact on total accounts receivable as of February 29, 2024 and May 31, 2023 or service revenue and results of operations for the three and nine months ended February 29, 2024 and February 28, 2023.

Professional Employer Organization ("PEO") Unbilled Receivables, Net of Advance Collections

Professional Employer Organization (“PEO”) unbilled receivables, net of advance collections: PEO unbilled receivables, including estimated revenues, offset by advance collections from clients, are recorded as PEO unbilled receivables, net of advance collections on the Company’s Consolidated Balance Sheets. As of February 29, 2024 and May 31, 2023, advance collections were $50.2 million and $12.5 million, respectively.

PEO Insurance Reserves

PEO insurance reserves: As part of its PEO solution, the Company offers workers’ compensation insurance and health insurance coverage to clients for the benefit of client employees. Workers’ compensation insurance is primarily provided under fully insured high deductible workers’ compensation insurance policies. Workers’ compensation insurance reserves are established to provide for the estimated costs of paying claims up to per occurrence liability limits. These reserves include estimates of certain expenses associated with processing and settling claims. For fiscal 2024, the Company has an aggregate maximum liability of $1.0 million for claims exceeding $1.0 million, and once met, the maximum individual claims liability is $1.0 million. For fiscal 2023, the Company had an aggregate maximum liability of $2.0 million for claims exceeding $1.0 million, and once met, the maximum individual claims liability is $1.0 million.

With respect to PEO health insurance coverage, the Company offers various health insurance plans that take the form of either fully insured guaranteed cost plans or fully insured insurance arrangements where the Company retains risk. A reserve for insurance arrangements where the Company retains risk is established to provide for the payment of claims in accordance with the Company’s service contract with the carrier. The claims reserve includes estimates for reported losses, plus amounts for those claims incurred but not reported, and estimates of certain expenses associated with processing and settling the claims. The Company’s maximum individual claims liability is $0.5 million under its policies covering both fiscal 2024 and fiscal 2023.

In establishing the PEO workers' compensation insurance reserves, the Company uses an independent actuarial estimate of undiscounted future cash payments that would be made to settle claims. Estimating the ultimate cost of future claims is an uncertain and complex process based upon historical loss experience and accepted actuarial methods and assumptions. These reserves are subject to change due to multiple factors, including economic trends, changes in legal liability law, and damage awards, all of which could materially impact the reserves as reported in the consolidated financial statements. Accordingly, final claim settlements may vary from the present estimates, particularly with workers’ compensation insurance where those payments may not occur until well into the future. The Company regularly reviews the adequacy of its estimated insurance reserves. Adjustments to previously established reserves are reflected in the results of operations for the period in which the adjustment is identified. Such adjustments could be significant, reflecting any combination of new and adverse or favorable trends.

Stock-Based Compensation Costs

Stock-based compensation costs: The Company has issued stock-based awards to employees and members of its Board of Directors (the “Board”) consisting of stock options, restricted stock units, and restricted stock awards. The Company accounts for all stock-based awards to employees and members of the Board as compensation costs in the consolidated financial statements based on their fair values measured as of the date of grant. These costs are recognized over the requisite service period. Stock-based compensation costs recognized were $14.4 million and $45.1 million for the three and nine months ended February 29, 2024, respectively, as compared with $16.3 million and $46.0 million for the three and nine months ended February 28, 2023, respectively. The methods and assumptions used in the determination of the fair value of stock-based awards are consistent with those described in the Company’s Form 10-K for fiscal 2023.

Recently Adopted and Issued Accounting Pronouncements

Recently adopted accounting pronouncements: Effective June 1, 2023, the Company adopted Accounting Standards Update (“ASU”) No. 2021-08 “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers,” which did not have a material impact on its consolidated financial statements.

Recently issued accounting pronouncements: In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. This ASU is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. This ASU is applicable to the Company’s Annual Report on Form 10-K for the fiscal year ending May 31, 2025, and subsequent interim periods, with early application permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

In December 2023, the FASB issued ASU No. 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU updates income tax disclosure requirements primarily by requiring specific categories and greater

disaggregation within the rate reconciliation and disaggregation of income taxes paid by jurisdiction. This ASU is effective for annual periods beginning after December 15, 2024 and is applicable to the Company’s fiscal year beginning June 1, 2025, with early application permitted. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

Other recent authoritative guidance issued by the FASB (including technical corrections to the FASB Accounting Standards Codification), the American Institute of Certified Public Accountants, and the Securities and Exchange Commission (“SEC”) did not or is not expected to have a material impact on the Company’s consolidated financial statements.
