1. Basis of Presentation

Insperity, Inc., a Delaware corporation (“Insperity,” “we,” “our,” and “us”), provides an array of human resources (“HR”) and business solutions designed to help improve business performance. Our most comprehensive HR services offerings are provided through our professional employer organization (“PEO”) services, known as our Insperity® HR360 solution (formerly our Workforce Optimization® solution) and Insperity® HR360 Select Edition (formerly our Workforce SynchronizationTM solution) (together, our “PEO HR Solutions”), which we provide by entering into a co-employment relationship with our clients. Our PEO HR Solutions encompass a broad range of HR functions, including payroll and employment administration, employee benefits, workers’ compensation, government compliance, performance management, and training and development services, along with our cloud-based human capital management solution, the Insperity PremierTM platform.

In addition to our PEO HR Solutions, we offer a comprehensive traditional payroll and human capital management solution, known as our Insperity HRCore™ solution (formerly our Workforce Acceleration™ solution), which we refer to as our “Traditional HR Solution”. We also offer a number of other business performance solutions, including Recruiting Services, Employment Screening, Retirement Services, and Insurance Services. These other products or services are offered separately or with our other solutions.

The Consolidated Financial Statements include the accounts of Insperity, Inc. and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

The accompanying Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements at and for the year ended December 31, 2024. Our Condensed Consolidated Balance Sheets at December 31, 2024 have been derived from the audited financial statements at that date, but do not include all of the information or footnotes required by GAAP for complete financial statements. Our Condensed Consolidated Balance Sheets at September 30, 2025 and our Consolidated Statements of Income for the three and nine month periods ended September 30, 2025 and 2024, our Consolidated Statements of Cash Flows for the nine month periods ended September 30, 2025 and 2024 and our Consolidated Statements of Stockholders' Equity for each of the three and nine month periods ended September 30, 2025 and 2024, have been prepared by us without audit. In the opinion of management, all adjustments necessary to present fairly the consolidated financial position, results of operations and cash flows have been made, and all such adjustments are of a normal recurring nature.

The results of operations for the interim periods are not necessarily indicative of the operating results for a full year or of future operations.

2. Accounting Policies

Health Insurance Costs

We provide group health insurance coverage under a single-employer plan that covers both our WSEEs in our PEO HR Solutions and our corporate employees and utilizes a national network of carriers, including UnitedHealthcare (“United”), UnitedHealthcare of California, Kaiser Permanente, Blue Shield of California, HMSA BlueCross BlueShield of Hawaii, and Harvard Pilgrim Health Care, formerly known as Tufts, all of which provide fully insured policies or service contracts.

Approximately 84% of our costs related to health insurance coverage are incurred under our policy with United. While the policy with United is a fully insured plan, as a result of certain contractual terms, we have accounted for this plan since its inception using a partially self-funded insurance accounting model. Effective January 1, 2020, under the amended agreement with United, we no longer have financial responsibilities for a participant’s annual claim costs that exceed $1 million (“Individual Claims Limit”). Accordingly, we record the cost of the United plan, including an estimate of the incurred claims, taxes and administrative fees (collectively the “Plan Costs”), as benefits expense, which is a component of direct costs, in our Consolidated Statements of Income. The estimated incurred but not reported claims are based upon: (1) the

Insperity | 2025 Third Quarter Form 10-Q 11

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

level of claims processed during each quarter; (2) estimated completion rates based upon recent claim development patterns under the plan; and (3) the number of participants in the plan, including both active and COBRA enrollees. Each reporting period, changes in the estimated ultimate costs resulting from claim trends, plan design and migration, participant demographics, and other factors are incorporated into the benefits costs, which requires a significant level of judgment.

Additionally, since the plan’s inception, under the terms of the contract, United establishes cash funding rates 90 days in advance of the beginning of a reporting quarter. If the Plan Costs for a reporting quarter are greater than the premiums paid and owed to United, a deficit in the plan would be incurred and a liability for the excess costs would be accrued in our Condensed Consolidated Balance Sheets. On the other hand, if the Plan Costs for the reporting quarter are less than the premiums paid and owed to United, a surplus in the plan would be incurred and we would record an asset for the excess premiums in our Condensed Consolidated Balance Sheets. The terms of the arrangement require us to maintain an accumulated cash surplus in the plan of $9 million, which is reported as long-term prepaid health insurance. In addition, United requires a deposit equal to approximately one day of claims funding activity, which was $7 million at September 30, 2025, and is included in deposits - health insurance as a long-term asset on our Condensed Consolidated Balance Sheets. As of September 30, 2025, Plan Costs were less than the net premiums paid and owed to United by $19 million, which is $10 million in excess of our agreed-upon $9 million surplus maintenance level. The $10 million difference is therefore reflected as a current asset and $9 million is reflected as a long-term asset on our Condensed Consolidated Balance Sheets at September 30, 2025. In addition, the premiums owed to United at September 30, 2025, were $26 million, which is included in accrued health insurance costs, a current liability, on our Condensed Consolidated Balance Sheets. Our benefits costs incurred in the first nine months of 2025 included an increase of $9 million for changes in estimated run-off related to prior periods, net of Individual Claims Limit. Our benefits costs incurred in the first nine months of 2024 included a decrease of $32 million for changes in estimated run-off related to prior periods, net of Individual Claims Limit.

Workers’ Compensation Costs

Our workers’ compensation coverage for our WSEEs in our PEO HR Solutions has been provided through arrangements with the Chubb Group of Insurance Companies or its predecessors (the “Chubb Program”) since 2007. The Chubb Program is fully insured in that Chubb has the responsibility to pay all claims incurred under the policy regardless of whether we satisfy our responsibilities. Under the Chubb Program, for claims incurred on or before September 30, 2019, we have financial responsibility to Chubb for the first $1 million layer of claims per occurrence and, for claims over $1 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed $1 million. Chubb bears the financial responsibility for all claims in excess of these levels. Effective for claims incurred on or after October 1, 2019, we have financial responsibility to Chubb for the first $1.5 million layer of claims per occurrence and, for claims over $1.5 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed $1.5 million.

Because we bear the financial responsibility for claims up to the levels noted above, such claims, which are the primary component of our workers’ compensation costs, are recorded in the period incurred. Workers’ compensation insurance includes ongoing health care and indemnity coverage whereby claims are paid over numerous years following the date of injury. Accordingly, the accrual of related incurred costs in each reporting period includes estimates, which take into account the ongoing development of claims and therefore requires a significant level of judgment.

We utilize a third-party actuary to estimate our loss development rate, which is primarily based upon the nature of WSEEs’ job responsibilities, the location of WSEEs, the historical frequency and severity of workers’ compensation claims, and an estimate of future cost trends. Each reporting period, changes in the actuarial assumptions resulting from changes in actual claims experience and other trends are incorporated into our workers’ compensation claims cost estimates. During the nine months ended September 30, 2025 and 2024, we reduced accrued workers’ compensation costs by $20 million and $25 million, respectively, for changes in estimated losses related to prior periods. Workers’ compensation cost estimates are discounted to present value at a rate based upon the U.S. Treasury rates that correspond with the weighted average estimated claim payout period (the average discount rate utilized was 4.0% in the 2025 period and 4.3% in the 2024 period) and are accreted over the estimated claim payment period and included as a component of direct costs in our Consolidated Statements of Income.

Insperity | 2025 Third Quarter Form 10-Q 12

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The following table provides the activity and balances related to incurred but not paid workers’ compensation claims:

The current portion of accrued workers’ compensation costs on our Condensed Consolidated Balance Sheets at September 30, 2025 and 2024 includes $2 million and $3 million, respectively, of workers’ compensation administrative fees.

The undiscounted accrued workers’ compensation costs were $227 million as of September 30, 2025 and $242 million as of September 30, 2024.

At the beginning of each policy period, the workers’ compensation insurance carrier establishes monthly funding requirements comprised of premium costs and funds to be set aside for payment of future claims (“claim funds”). The level of claim funds is primarily based upon anticipated WSEE payroll levels and expected workers’ compensation loss rates, as determined by the insurance carrier. Monies funded into the program for incurred claims expected to be paid within one year are primarily held as cash and money market funds (cash equivalents) and are recorded as restricted cash, a short-term asset, while the remainder of claim funds are included in deposits – workers’ compensation, a long-term asset in our Condensed Consolidated Balance Sheets. At September 30, 2025, we had restricted cash of $79 million and deposits – workers’ compensation of $147 million, of which $226 million was held in trust bank accounts.

Our estimate of incurred claim costs expected to be paid within one year is included in short-term liabilities, while our estimate of incurred claim costs expected to be paid beyond one year is included in long-term liabilities on our Condensed Consolidated Balance Sheets.

Revenue and Direct Cost Recognition

We enter into contracts with our PEO HR Solutions customers for human resources services based on a stated rate and price in the contract. Our contracts generally establish pricing for a period of 12 months and are generally cancellable at any time by either party with 30-days’ notice. Our performance obligations are satisfied as services are rendered each month. The term between invoicing and when our performance obligations are satisfied is not significant. Our payment terms typically require payment concurrently with the invoicing of our PEO services. We do not have significant financing components or significant payment terms.

Our revenue is generally recognized ratably over the payroll period as WSEEs perform their service at the client worksite in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers. Customers are invoiced concurrently with each periodic payroll of its WSEEs. Revenues that have been recognized but not invoiced represent unbilled accounts receivable of $882 million and $810 million at September 30, 2025 and December 31, 2024, respectively, and are included in accounts receivable, net on our Condensed Consolidated Balance Sheets.

Pursuant to the “practical expedients” provided under ASC 340-40, Other Assets and Deferred Costs - Contracts with Customers, we expense sales commissions when incurred because the terms of our contracts are cancellable by either party with a 30-day notice. These costs are recorded in commissions in our Consolidated Statements of Income.

Insperity | 2025 Third Quarter Form 10-Q 13

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Our revenue for our PEO HR Solutions by geographic region and for our other products and services offerings are as follows:

Our PEO HR Solutions revenues are primarily derived from our gross billings, which are based on (1) the payroll cost of our WSEEs; and (2) a markup computed as a percentage of the payroll cost. The gross billings are invoiced concurrently with each periodic payroll of our WSEEs. Revenues, which exclude the payroll cost component of gross billings and therefore consist solely of the markup, are recognized ratably over the payroll period as WSEEs perform their service at the client worksite.

In determining the pricing of the markup component of our gross billings, we take into consideration our estimates of the costs directly associated with our WSEEs, including payroll taxes, benefits and workers’ compensation costs, plus an acceptable gross profit margin. As a result, our operating results are significantly impacted by our ability to accurately estimate our direct costs relative to the revenues derived from the markup component of our gross billings.

Revenues are comprised of gross billings less WSEE payroll costs as follows:

Consistent with our revenue recognition policy, our direct costs do not include the payroll cost of our WSEEs. Our direct costs associated with our revenue generating activities are primarily comprised of all other costs related to our WSEEs, such as the employer portion of payroll-related taxes, employee benefit plan premiums and workers’ compensation insurance costs.

Segment Reporting

ASC 280, Segment Reporting establishes standards for reporting information about operating segments on a basis consistent with our internal organizational structure as well as information about geographical areas and business segments. Based on management’s assessment, we determined that we have only one operating segment and therefore one reportable segment, HR Solutions, as defined by ASC 280.

The accounting policies of the HR Solutions segment are the same as those described in the summary of significant accounting policies. The measure of segment assets is reported on our Condensed Consolidated Balance Sheets as total assets, and the chief operating decision maker (“CODM”) assesses performance and decides how to allocate resources based on net income as reported in our Consolidated Statements of Income.

The CODM reviews revenues and expenses at the consolidated level as disclosed in our Consolidated Statements of Income and uses net income to evaluate income generated from segment assets (return on assets) in deciding whether to reinvest profits into our HR Solutions segment or into other areas of the entity, such as for acquisitions or to pay dividends.

Insperity | 2025 Third Quarter Form 10-Q 14

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Net income is also used to monitor budget versus actual results and in competitive analysis by benchmarking to our competitors. The competitive analysis and the monitoring of budgeted versus actual results are used in assessing the segment’s performance and in establishing management’s compensation.

3. Other Balance Sheet Information

Cash, Cash Equivalents and Marketable Securities

The following table summarizes our cash and investments in cash equivalents and marketable securities held by investment managers and overnight investments:

Our cash and overnight holdings fluctuate based on the timing of clients’ payroll processing cycles. Our cash, cash equivalents and marketable securities at September 30, 2025 and December 31, 2024 included $284 million and $830 million, respectively, of funds associated with federal and state income tax withholdings, employment taxes, and other payroll deductions, as well as $36 million and $91 million, respectively, in client prepayments. In addition, $440 million of client employee retention tax credits received on their behalf from the Internal Revenue Service during the fourth quarter of 2024 were distributed to clients in early 2025.

Please read Note 2. “Accounting Policies,” for a discussion of our accounting policies for deposits – workers’ compensation and restricted cash.

4. Fair Value Measurements

We account for our financial assets in accordance with ASC 820, Fair Value Measurement. This standard defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The fair value measurement disclosures are grouped into three levels based on valuation factors:

• Level 1 - quoted prices in active markets using identical assets
• Level 2 - significant other observable inputs, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other observable inputs
• Level 3 - significant unobservable inputs

Insperity | 2025 Third Quarter Form 10-Q 16

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Fair Value of Instruments Measured and Recognized at Fair Value

The following table summarizes the levels of fair value measurements of our financial assets:

Please read Note 3. “Other Balance Sheet Information,” for additional information.

Our valuation techniques used to measure fair value for these securities during the period consisted primarily of third-party pricing services that utilized actual market data such as trades of comparable bond issues, broker/dealer quotations for the same or similar investments in active markets and other observable inputs.

The following is a summary of our available-for-sale marketable securities:

As of September 30, 2025, the contractual maturities of all marketable securities in our portfolio were less than one year.

Fair Value of Other Financial Instruments

The carrying amounts of cash, cash equivalents, restricted cash, accounts receivable, deposits and accounts payable approximate their fair values due to the short-term maturities of these instruments.

As of September 30, 2025, the carrying value of borrowings under our revolving credit facility approximates fair value and was classified as Level 2 in the fair value hierarchy. Please read Note 5, “Long-Term Debt,” for additional information.

5. Long-Term Debt

We have a revolving credit facility (the “Facility”) with a borrowing capacity of up to $650 million. The Facility may be further increased to $700 million based on the terms and subject to the conditions set forth in the agreement relating to the Facility (as amended, the “Credit Agreement”). The Facility is available for working capital and general corporate purposes, including acquisitions, stock repurchases and issuances of letters of credit. Our obligations under the Facility are secured by 100% of the stock of our captive insurance subsidiary and are guaranteed by all of our subsidiaries other than our captive insurance subsidiary and certain other excluded subsidiaries. At September 30, 2025, our outstanding balance on the Facility was $369 million, and we had an outstanding $1 million letter of credit issued under the Facility, resulting in an available borrowing capacity of $280 million.

The Facility matures on June 30, 2027. Borrowings under the Facility bear interest at an annual rate equal to an alternate base rate or Adjusted Term SOFR for term SOFR loans, in either case plus an applicable margin. Adjusted Term SOFR is a forward-looking term rate based on the secured overnight financing rate plus a spread adjustment, which ranges from 0.10% to 0.25% depending on the interest period and type of loan. Depending on our leverage ratio, the applicable margin

Insperity | 2025 Third Quarter Form 10-Q 17

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

varies (1) in the case of SOFR loans, from 1.50% to 2.25% and (2) in the case of alternate base rate loans, from 0.00% to 0.50%. The alternate base rate is the highest of (1) the prime rate most recently published in The Wall Street Journal, (2) the federal funds rate plus 0.50%; and (3) the Adjusted Term SOFR rate plus 2.00%. We also pay an unused commitment fee on the average daily unused portion of the Facility at a rate of 0.25% per year. The average interest rate for the nine month period ended September 30, 2025 was 6.2%. Interest expense and unused commitment fees are recorded in other income (expense).

The Facility contains both affirmative and negative covenants that we believe are customary for arrangements of this nature. Covenants include, but are not limited to, limitations on our ability to incur additional indebtedness, sell material assets, retire, redeem or otherwise reacquire our capital stock, acquire the capital stock or assets of another business, make investments and pay dividends. In addition, the Credit Agreement requires us to comply with financial covenants limiting our total funded debt, minimum interest coverage ratio, and maximum leverage ratio. Effective March 31, 2025, we amended the Facility to exclude dividends from the interest coverage ratio financial covenant. We were in compliance with all financial covenants under the Credit Agreement at September 30, 2025.

6. Stockholders' Equity

During the nine months ended September 30, 2025, we repurchased or withheld an aggregate of 225,459 shares of our common stock, as described below.

Repurchase Program

Our Board of Directors (the “Board”) has authorized a program to repurchase shares of our outstanding common stock (“Repurchase Program”). The purchases may be made from time to time in the open market or directly from stockholders at prevailing market prices based on market conditions and other factors. During the nine months ended September 30, 2025, 45,000 shares were repurchased under the Repurchase Program. As of September 30, 2025, we were authorized to repurchase an additional 1,407,764 shares under the Repurchase Program.

Withheld Shares

During the nine months ended September 30, 2025, we withheld 180,459 shares to satisfy tax withholding obligations for the vesting of long-term incentive and restricted stock unit awards.

Dividends

The Board declared and paid quarterly dividends as follows:

During the nine months ended September 30, 2025 and 2024, we declared and paid dividends totaling $68 million and $67 million, respectively.

7. Earnings Per Share

Basic EPS is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income by the weighted average number of common shares outstanding during the period, plus the dilutive effect of time-based and performance-based restricted stock units (“RSUs”).

Key Operating Metrics

We monitor certain key metrics to measure our performance, including:

• WSEEs
• Adjusted EBITDA
• Adjusted EPS

Our growth in the number of WSEEs paid is affected by three primary sources: new client sales, client retention and the net change in WSEEs paid at existing clients through new hires and employee terminations.

• During Q3 2025, average WSEEs paid increased 1% compared to Q3 2024. The number of WSEEs paid from new client sales and the net change in our client base slightly decreased compared with Q3 2024, while client retention remained consistent with Q3 2024.
• During the first nine months of 2025 (“YTD 2025”), average WSEEs paid increased 1% compared to the first nine months of 2024 (“YTD 2024”). The number of WSEEs paid from new client sales, client retention and the net change in our client base increased when compared to YTD 2024.

Revenues

Our PEO HR Solutions revenues are primarily derived from our gross billings, which are based on (1) the payroll cost of our WSEEs and (2) a monthly markup component.

Our revenues are primarily dependent on the number of clients enrolled, the resulting number of WSEEs paid each period and the number of WSEEs enrolled in our benefit plans. Because our monthly markup is computed in part as a percentage of payroll cost, certain revenues are also affected by the payroll cost of WSEEs, which may fluctuate based on the composition of the WSEE base, inflationary effects on wage levels and differences in the local economies of our markets.

Gross Profit

In determining the pricing of the markup component of our gross billings, we take into consideration our estimates of the costs directly associated with our WSEEs, including payroll taxes, benefits and workers’ compensation costs, plus an acceptable gross profit margin.

Our gross profit per WSEE and operating results are significantly impacted by our ability to accurately estimate direct costs and our ability to incorporate changes in these costs into the gross billings charged to PEO HR Solutions clients, which are subject to pricing arrangements that are typically renewed annually. We use gross profit per WSEE per month as our principal measurement of relative performance at the gross profit level.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Gross Profit per WSEE per Month and Year-over-Year Growth Percentage

Third Quarter 2025 Compared to Third Quarter 2024

Gross profit for Q3 2025 decreased 15% to $195 million compared to $229 million in Q3 2024. Gross profit per WSEE per month for Q3 2025 decreased $39 to $208 compared to $247 in Q3 2024 due primarily to higher direct costs, offset in part by higher average pricing, as discussed below.

Our pricing objectives attempt to achieve a level of revenue per WSEE that matches or exceeds changes in primary direct costs and operating expenses. Our revenues per WSEE per month increased $46 due to higher average pricing of 3%.

The net increase in direct costs between Q3 2025 and Q3 2024 attributable to the changes in cost estimates for benefits and workers’ compensation totaled $15 million as discussed below. The $85 per WSEE per month increase in direct costs is due primarily to the direct cost component changes as follows:

• The cost of group health insurance and related employee benefits increased $60 per WSEE per month and increased 9.1% on a cost per covered employee basis driven by elevated inpatient, outpatient and pharmacy trends and frequency of large claim activity in Q3 2025 as compared to Q3 2024.
• The percentage of WSEEs covered under our health insurance plans was 62% in Q3 2025 compared to 63% in Q3 2024.
• Reported results include changes in estimated claims run-off related to prior periods, which did not impact costs in Q3 2025 compared to a decrease in costs of $12 million, or $13 per WSEE per month, in Q3 2024.

Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Health Insurance Costs,” for a discussion of our accounting for health insurance costs.

Workers’ compensation costs

• Workers’ compensation costs increased 15%, or $3 per WSEE per month, in Q3 2025 compared to Q3 2024.
• As a percentage of non-bonus payroll cost, workers’ compensation costs were 0.27% in Q3 2025 compared to 0.25% in Q3 2024.

Insperity | 2025 Third Quarter Form 10-Q 28

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

• Our continued discipline around our client selection, workplace safely and claims management has allowed for claims to be closed out at amounts below our original cost estimates, resulting in a reduction in workers’ compensation costs of $5 million, or 0.05% of non-bonus payroll costs in Q3 2025, compared to a reduction of $8 million, or 0.09% of non-bonus payroll costs in Q3 2024.

Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Workers’ Compensation Costs,” for a discussion of our accounting for workers’ compensation costs.

Payroll tax costs

• Payroll taxes increased 5% on a 4% increase in payroll costs, or $24 per WSEE per month.
• Payroll taxes as a percentage of payroll costs were 6% in both Q3 2025 and Q3 2024.

First Nine Months 2025 Compared to First Nine Months 2024

Gross profit for YTD 2025 decreased 13% to $728 million compared to $834 million in YTD 2024. Gross profit per WSEE per month for YTD 2025 decreased $41 to $261 compared to $302 in YTD 2024 due primarily to higher direct costs, offset in part by higher average pricing, as discussed below.

Our pricing objectives attempt to achieve a level of revenue per WSEE that matches or exceeds changes in primary direct costs and operating expenses. Our revenues per WSEE per month increased $48 due to higher average pricing of 3%.

The net increase in direct costs between YTD 2025 and YTD 2024 attributable to the changes in cost estimates for benefits and workers’ compensation totaled $46 million as discussed below. The $89 per WSEE per month increase in direct costs is due primarily to the direct cost component changes as follows:

Benefits costs

• The cost of group health insurance and related employee benefits increased $60 per WSEE per month, or 9.0% on a cost per covered employee basis driven by elevated inpatient, outpatient and pharmacy trends and frequency of large claim activity in YTD 2025 as compared to YTD 2024.
• The percentage of WSEEs covered under our health insurance plans was 63% in YTD 2025 compared to 64% in YTD 2024.
• Reported results include changes in estimated claims run-off related to prior periods, which was an increase in costs of $9 million, or $3 per WSEE per month, in YTD 2025 compared to a decrease in costs of $32 million, or $12 per WSEE per month, in YTD 2024.

Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Health Insurance Costs,” for a discussion of our accounting for health insurance costs.

Workers’ compensation costs

• Workers’ compensation costs increased 11%, or $2 per WSEE per month, in YTD 2025 compared to YTD 2024.
• As a percentage of non-bonus payroll cost, workers’ compensation costs were 0.25% in YTD 2025 compared to 0.23% in YTD 2024.
• Our continued discipline around our client selection, workplace safely and claims management has allowed for claims to be closed out at amounts below our original cost estimates, resulting in a reduction in workers’ compensation costs of $20 million, or 0.08% of non-bonus payroll costs, in YTD 2025 compared to a reduction of $25 million, or 0.11% of non-bonus payroll costs, in YTD 2024.

Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Workers' Compensation Costs,” for a discussion of our accounting for workers’ compensation costs.

Payroll tax costs

• Payroll taxes increased 5% on a 4% increase in payroll costs, or $26 per WSEE per month.

Insperity | 2025 Third Quarter Form 10-Q 29

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

• Payroll taxes as a percentage of payroll costs were 7% in both YTD 2025 and YTD 2024.

Operating Expenses

• Salaries, wages and payroll taxes — Salaries, wages and payroll taxes (“Salaries”) are primarily a function of the number of corporate employees, their associated average pay and any additional cash incentive compensation.
• Stock-based compensation — Our stock-based compensation relates to the recognition of non-cash compensation expense over the requisite service period of time-based and performance-based awards.
• Commissions — Commissions expense consists primarily of amounts paid to sales managers and other sales personnel, including business performance advisors (“BPAs”), as well as channel referral fees. Commissions are based on new accounts sold and a percentage of revenue generated by such personnel.
• Advertising — Advertising expense primarily consists of media advertising and other business promotions in our current and anticipated sales markets.
• General and administrative expenses — Our general and administrative expenses primarily include:
  • rent expenses related to our service centers and sales offices
  • outside professional service fees related to legal, consulting and accounting services
  • administrative costs, such as postage, printing and supplies
  • employee travel and training expenses
  • facility costs, including repairs and maintenance
  • technology costs, including software-as-a-service (“SaaS”) subscription costs, amortization of SaaS implementation costs and third-party costs related to our strategic partnership with Workday, Inc.
• Depreciation and amortization — Depreciation and amortization expense is primarily a function of our capital investments in corporate facilities, service centers, sales offices, software development, and technology infrastructure.

Third Quarter 2025 Compared to Third Quarter 2024

The following table presents certain information related to our operating expenses:

Operating expenses for Q3 2025 decreased 4% to $220 million compared to $228 million in Q3 2024. Operating expenses per WSEE per month for Q3 2025 decreased 4% to $235 compared to $246 in Q3 2024.

• General and administrative expenses for Q3 2025 decreased 15% to $45 million, or $9 per WSEE per month, compared to Q3 2024. The decrease was primarily due to decreased professional services fees, which includes expenses related to the implementation of our Workday strategic partnership, travel and training expenses, partially offset by increases in software licensing and maintenance costs.

First Nine Months 2025 Compared to First Nine Months 2024

The following table presents certain information related to our operating expenses:

Operating expenses for YTD 2025 decreased 1% to $692 million compared to $702 million in YTD 2024. Operating expenses per WSEE per month for YTD 2025 decreased 2% to $248 compared to $254 in YTD 2024.

Insperity | 2025 Third Quarter Form 10-Q 31

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

• General and administrative expenses for YTD 2025 decreased 8% to $154 million, or $6 per WSEE per month, compared to YTD 2024. The decrease was primarily due to decreased professional services fees, which includes expenses related to the implementation of our Workday strategic partnership, travel and training, and amortization of SaaS implementation costs, partially offset by increases in software licensing and maintenance costs.

Other Income (Expense)

Interest income decreased $4 million in YTD 2025 compared to YTD 2024 due to interest rate decreases on overnight, investment and deposit holdings.

Interest expense decreased $3 million in YTD 2025 compared to YTD 2024 due to decreases in interest rates charged on borrowings under our credit facility.

Income Tax Expense

For the nine months ended September 30, 2025, our provision for income taxes differed from the U.S. statutory rate primarily due to state income taxes, non-deductible expenses and vesting of restricted and long-term incentive stock awards. The decrease in net income without a corresponding change in non-deductible expenses resulted in a higher effective tax rate for the period. During the first nine months of 2025 we recognized a $1 million income tax expense related to the vesting of long-term incentive and restricted stock awards. During the first nine months of 2024 we did not recognize an income tax benefit or expense related to the vesting of long-term incentive and restricted stock awards.

On July 4, 2025, H.R.1, which is known as the “One Big Beautiful Bill Act,” was signed into federal law. This law includes significant changes to federal tax law and other regulatory provisions that may impact us. ASC 740, “Income Taxes”, requires the effect of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation is enacted. We have evaluated the provisions of H.R.1 and the potential effects on our financial position, results of operations, and cash flows. Although there is no impact to our effective tax rate, we are accelerating tax deductions for unamortized software development costs.

Non-GAAP Financial Measures

Non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of the non-GAAP financial measures used to their most directly comparable GAAP financial measures as provided in the tables below.

• Non-GAAP Measure Definition Benefit of Non-GAAP Measure
• Non-bonus payroll cost Non-bonus payroll cost is a non-GAAP financial measure that excludes the impact of bonus payrolls paid to our WSEEs. Our management refers to non-bonus payroll cost in analyzing, reporting and forecasting our workers’ compensation costs. Bonus payroll cost varies from period to period, but has no direct impact to our ultimate workers’ compensation costs under the current program. We include these non-GAAP financial measures because we believe they are useful to investors in allowing for greater transparency related to the costs incurred under our current workers’ compensation program.
• Adjusted cash, cash equivalents and marketable securities Excludes funds associated with:
• federal and state income tax withholdings,
• employment taxes,
• other payroll deductions, and
• client prepayments. We believe that the exclusion of the identified items helps us reflect the fundamentals of our underlying business model and analyze results against our expectations, against prior periods, and to plan for future periods by focusing on our underlying operations. We believe that the adjusted results provide relevant and useful information for investors because they allow investors to view performance in a manner similar to the method used by management and improves their ability to understand and assess our operating performance. Adjusted EBITDA is used by our lenders to assess our leverage and ability to make interest payments.
• EBITDA Represents net income computed in accordance with GAAP, plus:
• interest expense,
• income tax expense,
• depreciation and amortization expense, and
• amortization of SaaS implementation costs.
• Adjusted EBITDA Represents EBITDA plus:
• non-cash stock-based compensation.
• Adjusted net income Represents net income computed in accordance with GAAP, excluding:
• non-cash stock-based compensation.
• Adjusted EPS Represents diluted net income per share computed in accordance with GAAP, excluding:
• non-cash stock-based compensation.

Liquidity and Capital Resources

We periodically evaluate our liquidity requirements, capital needs and availability of resources in view of, among other things, our expansion plans, stock repurchases, potential acquisitions, debt service requirements and other operating cash needs. To meet short-term liquidity requirements, which are primarily the payment of direct costs and operating expenses, we rely primarily on cash from operations. Longer-term projects, large stock repurchases or significant acquisitions may be financed with public or private debt or equity. We have a revolving credit facility (“Facility”) with a syndicate of financial institutions with a current borrowing capacity of $650 million. The Facility is available for working capital and general corporate purposes, including acquisitions and stock repurchases. We have in the past sought, and may in the future seek, to raise additional capital or take other steps to increase or manage our liquidity and capital resources.

We had $440 million in cash, cash equivalents and marketable securities at September 30, 2025, of which approximately $284 million was payable in October 2025 for withheld federal and state income taxes, employment taxes and other payroll deductions. Approximately $36 million represented client prepayments that were invoiced in October 2025. At September 30, 2025, we had working capital of $172 million compared to $155 million at December 31, 2024. We currently believe that our cash on hand, marketable securities, cash flows from operations, and availability under the Facility will be adequate to meet our liquidity requirements for the remainder of 2025. We intend to rely on these same sources, as well as public and private debt or equity financing, to meet our longer-term liquidity and capital needs.

As of September 30, 2025, we had outstanding letters of credit and borrowings totaling $370 million under the Facility. Please read Note 5 to the Consolidated Financial Statements, “Long-Term Debt,” for additional information.

Cash Flows from Operating Activities

Net cash used in operating activities in the first nine months of 2025 was $533 million. Our primary source of cash from operations is the comprehensive service fee and payroll funding we collect from our clients. Our cash and cash equivalents, and thus our reported cash flows from operating activities, are significantly impacted by various external and internal factors, which are reflected in part by the changes in our balance sheet accounts. These include the following:

• Timing of client payments / payroll taxes — We typically collect our comprehensive service fee, along with the client’s payroll funding, from clients no later than the same day as the payment of WSEE payrolls and associated payroll taxes. Therefore, the last business day of a reporting period has a substantial impact on our reporting of operating cash flows. For example, many WSEEs are paid on Fridays; therefore, operating cash flows decrease in the reporting periods that end on a Friday or a Monday. In the nine months ended September 30, 2025, the last business day of the reporting period was a Tuesday, client prepayments were $36 million and employment taxes and other deductions were $284 million. In the nine months ended September 30, 2024, the last business day of the reporting period was a Monday, client prepayments were $19 million and employment taxes and other deductions were $255 million. In addition, $440 million of client employee retention tax credits received on their behalf from the Internal Revenue Service during the fourth quarter of 2024 were distributed to clients in early 2025.

Insperity | 2025 Third Quarter Form 10-Q 36

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

• Workers’ compensation plan funding — During YTD 2025 and YTD 2024, we received $28 million and $38 million, respectively, for the return of excess claim funds related to the workers’ compensation program, which resulted in an increase in working capital.
• Medical plan funding — Our health care contract with United establishes participant cash funding rates 90 days in advance of the beginning of a reporting quarter. Therefore, changes in the participation level of the United plan have a direct impact on our operating cash flows. In addition, changes to the funding rates, which are solely determined by United based primarily upon recent claim history and anticipated cost trends, also have a significant impact on our operating cash flows. As of September 30, 2025, Plan Costs were less than the net premiums paid and owed to United by $19 million, which is $10 million in excess of our agreed-upon $9 million surplus maintenance level. The $10 million difference is therefore reflected as a current asset and $9 million is reflected as a long-term asset on our Condensed Consolidated Balance Sheets at September 30, 2025. In addition, the premiums owed to United at September 30, 2025, were $26 million, which is included in accrued health insurance costs, a current liability, on our Condensed Consolidated Balance Sheets.
• Operating results — Our adjusted net income has a significant impact on our operating cash flows. Our adjusted net income decreased 54% to $61 million in the first nine months of 2025, compared to $134 million in the first nine months of 2024. Please read “Results of Operations.”

Cash Flows from Investing Activities

Net cash flows used in investing activities were $22 million for the nine months ended September 30, 2025, primarily due to property and equipment purchases.

Cash Flows from Financing Activities

Net cash flows used in financing activities were $101 million for the nine months ended September 30, 2025. We paid $68 million in dividends and repurchased or withheld $19 million in stock. In addition, client funds liability and other financing activities decreased by $14 million.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK AND CONTROLS AND PROCEDURES

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are primarily exposed to market risks from fluctuations in interest rates and the effects of those fluctuations on the market values of our cash equivalent short-term investments, our available-for-sale marketable securities and our borrowings under our Facility, which bears interest at a variable market rate. As of September 30, 2025, we had outstanding letters of credit and borrowings totaling $370 million under the Facility. Please read Note 5 to the Consolidated Financial Statements, “Long-Term Debt,” for additional information.

The cash equivalent short-term investments consist primarily of overnight investments, which are not significantly exposed to interest rate risk, except to the extent that changes in interest rates will ultimately affect the amount of interest income earned on these investments. Our available-for-sale marketable securities are subject to interest rate risk because these securities generally include a fixed interest rate. As a result, the market values of these securities are affected by changes in prevailing interest rates.

We attempt to limit our exposure to interest rate risk primarily through diversification and low investment turnover. Our investment policy is designed to maximize after-tax interest income while preserving our principal investment. As a result, our marketable securities consist of primarily short-term U.S. Government Securities.

Item 4. Controls and Procedures

In accordance with Rules 13a-15 and 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2025.

There has been no change in our internal control over financial reporting that occurred during the three months ended September 30, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

The following table provides information about purchases by Insperity during the three months ended September 30, 2025 of equity securities that are registered by Insperity pursuant to Section 12 of the Exchange Act:

(1) During the three months ended September 30, 2025, 592 shares of stock were withheld to satisfy tax-withholding obligations arising in conjunction with the vesting of restricted stock units. The required withholding is calculated using the closing sales price reported by the New York Stock Exchange on the date prior to the applicable vesting date. These shares are not subject to the repurchase program.

(2) Our Board of Directors has approved a program to repurchase shares of our outstanding common stock, which was originally announced on January 28, 1999. From time to time, our Board of Directors has increased the number of shares authorized to be repurchased under the program. On August 1, 2023, we announced that our Board of Directors had authorized an increase of 2,000,000 shares that may be repurchased under the program. As of September 30, 2025, we were authorized to repurchase an additional 1,407,764 shares under the program. Unless terminated earlier by resolution of our Board of Directors, the repurchase program will expire when we have repurchased all shares authorized for repurchase under the repurchase program.

Item 5. Other Information
