The following table provides information about purchases by Insperity during the three months ended March 31, 2026 of equity securities that are registered by Insperity pursuant to Section 12 of the Exchange Act:

(1)During the three months ended March 31, 2026, 170,915 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 March 31, 2026, 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.
