During the six months ended June 30, 2025 and 2024, we granted restricted stock units (which we refer to as “RSUs”) covering 0.2 million and 0.2 million shares of common stock, respectively, with a grant date fair value of $76.38 and $85.84 per share, respectively, that vest over a three year period. During the six months ended June 30, 2025 and 2024, we granted 16.0 thousand and 11.0 thousand shares of common stock, respectively, on an unrestricted basis (which we refer to as “stock awards”) with a grant date fair value of $53.26 and $82.84 per share, respectively, to our non-employee directors.

During the six months ended June 30, 2025, we granted performance share units (which we refer to as “PSUs”) covering up to 0.5 million shares of common stock assuming maximum level of performance with a weighted-average grant date fair value of $67.01 per share that are subject to service, performance, and market vesting conditions. The quantity of shares that will vest and be issued upon settlement of the PSUs ranges from 0% to up to 250% of a targeted number of shares depending upon the participant and will be determined based on achievement of three-year cumulative revenue and three-year cumulative adjusted pre-tax income performance goals. The ultimate share payout may then be adjusted by a relative total shareholder return modifier based on our three-year cumulative total stockholder return (which we refer to as “TSR”) relative to the average TSR of all companies in a defined peer group, with the potential to decrease the payout by 10% or increase it up to 20%. We utilize the Monte Carlo simulation model to determine the fair value of PSUs that contain market conditions, and stock-based compensation expense is recognized ratably for awards subject to market conditions regardless of whether the market condition is satisfied, provided that the requisite service has been met. During the six months ended June 30, 2024, we granted PSUs covering up to 0.3 million shares of common stock assuming maximum level of performance with a grant date fair value of $82.23 per share that are subject to both service and performance vesting conditions. The quantity of shares that will ultimately vest and be issued upon settlement of the PSUs ranges from 0% to 250% of a targeted number of shares and will be determined based on achievement of a three-year cumulative adjusted pre-tax income performance goal. During the six months ended June 30, 2025 and 2024, we issued 0.4 million and 0.2 million shares of common stock, respectively, upon the vesting

and settlement of PSUs that were granted in previous periods. Approximately 1.1 million shares will vest from 2026 to 2028 if the defined maximum performance targets are met and, for applicable awards, if the defined maximum TSR conditions are met, and no shares will vest if the defined minimum performance targets are not met.

A summary of our outstanding RSUs and PSUs, assuming the current estimated level of performance achievement, are as follows (in thousands, except years):

During the three months ended June 30, 2025 and 2024, we recognized stock-based compensation expense of $7.9 million and $7.9 million, respectively. During the six months ended June 30, 2025 and 2024, we recognized stock-based compensation expense of $8.2 million and $10.7 million, respectively. Stock-based compensation expense is included in selling, general, and administrative expense on our condensed consolidated statements of operations. Stock-based compensation expense for PSUs is initially estimated based on target performance achievement and adjusted as appropriate throughout the performance period. Accordingly, future compensation cost associated with outstanding PSUs may increase or decrease based on the probability and extent of achievement with respect to the applicable performance measures. During the three and six months ended June 30, 2025, in accordance with ASC 718, Compensation—Stock Compensation, we updated our recognition of stock-based compensation expense associated with previously granted PSU awards to reflect probable financial results as they relate to the performance goals of the awards. Accordingly, our estimate of the number of shares which will ultimately vest and be issued upon settlement of certain PSU awards increased by a total of 0.2 million shares during the three months ended June 30, 2025, and increased by approximately 40 thousand shares during the six months ended June 30, 2025. During the three months ended June 30, 2025, we recorded a cumulative adjustment to increase stock-based compensation expense of $1.0 million ($0.8 million net of tax), or $0.03 per basic share and $0.02 per diluted share. During the six months ended June 30, 2025, we recorded a cumulative adjustment to reduce stock-based compensation expense of $4.7 million ($3.5 million net of tax), or $0.12 per basic share and $0.11 per diluted share.
