Us, fair value is calculated using the closing price of our common stock on the NYSE on the date of grant. The grant value of the 2024 LTIP Awards is shown at target. Actual 2024 LTIP Awards may range from 0% to 200% of the target number of phantom shares if below threshold level is not achieved or the maximum performance level is achieved. For the relevant assumptions used to determine the valuation of our stock awards, refer to

#### Insperity412025 Proxy Statement
Note 9, “Incentive Plans,” in the Notes to Consolidated Financial Statements included in our annual report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 10, 2025. The terms of the RSU awards provide for three-year vesting and the payment of dividend equivalents on all unvested shares. The 2024 LTIP Awards are payable in shares of our common stock and include dividend equivalents, payable in additional shares of our common stock, with respect to the number of phantom shares actually earned pursuant to the 2024 LTIP Awards if and to the extent dividends are paid on our common stock during the performance period.

5 Mr. Allison’s 2024 target AIP reflects his November 2024 promotion, but was paid based upon eligible compensation earned in 2024.
