STOCK-BASED COMPENSATION
Stock-based Compensation Plans
The Company maintains certain stock-based compensation plans that were approved by the Company’s stockholders and are administered by the Board of Directors (the “Board”) or the Compensation and Organization Committee of the Board (the “Compensation Committee”). The stock-based compensation plans provide for the granting of stock options, restricted stock awards, RSUs, performance awards, stock appreciation rights and stock bonuses to employees, non-employee directors, consultants, and service providers.
As of December 31, 2025, the Company’s outstanding stock-based compensation plans and agreements include the 2021 Omnibus Incentive Plan (the “2021 Plan”), 2016 Stock Incentive Plan (the “2016 Plan”), 2011 Stock Incentive Plan (the “2011 Plan”), the 2009 Stock Incentive Plan (the “2009 Plan”). The 2021 Plan replaced the 2016 Plan and the Company ceased granting any new awards under the 2016 Plan. The number of shares initially reserved for issuance under the 2021 Plan was (i) 1,450,000 plus (ii) the total number of shares of common stock available for issuance under the 2016 Plan, plus (iii) any shares of common stock that are subject to awards forfeited, cancelled, expired, terminated or otherwise lapsed or settled in cash, in whole or in part, without the delivery of shares under the 2016 Plan. The 2011 Plan and 2009 Plan have expired and no awards are available for issuance under these expired plans. As of December 31, 2025, there were 772,585 shares available for future grants under the 2021 Plan.

Intrinsic value is calculated for in-the-money options (exercise price less than market price) as the difference between the market price of $78.43, which was the closing price of the Company’s common stock as of December 31, 2025, and the weighted average exercise price of the underlying stock options, multiplied by the number of options outstanding and/or exercisable. Shares are distributed from the Company’s authorized but unissued reserve upon the exercise of stock options. As of December 31, 2025, there was no unrecognized compensation cost related to stock options.

__________
(a)Represents additional PRSUs earned related to above-target achievement of performance conditions, the achievement of which was based upon predefined performance targets established by the Compensation Committee at the initial grant date.
For the Company’s PRSUs, in addition to service conditions, the ultimate number of shares earned depends on the achievement of financial or market-based performance conditions. The financial performance condition is based on the Company’s sales. The market conditions are based on the Company’s achievement of a relative total shareholder return (“TSR”) performance requirement, on a percentile basis, compared to a defined group of peer companies over three year performance periods.
At December 31, 2025, there was $9.4 million of total unrecognized compensation cost related to unvested PRSUs, which is expected to be recognized over a weighted-average period of approximately 1.7 years. The fair value of PRSU shares vested during 2025 and 2024 was $21.9 million and $19.8 million, respectively. The weighted average grant date fair value of PRSUs granted during 2025, 2024 and 2023 was $149.99, $110.54 and $74.32, respectively.
(11.)     STOCK-BASED COMPENSATION (Continued)
The grant-date fair values of the market-based portion of the PRSUs granted during 2025, 2024 and 2023 were determined using the Monte Carlo valuation model on the date of grant. The weighted average fair value and assumptions used to value the TSR portion of the PRSUs granted are as follows:
 202520242023
Weighted average fair value$162.62 $117.96 $74.29

Expected life (in years)3.03.03.0
Expected dividend yield— %— %— %
The valuation of the TSR portion of the PRSUs granted during 2025, 2024 and 2023 also reflects a weighted average illiquidity discount of 8.78%, 8.00% and 11.23%, respectively, related to the period that recipients are restricted from selling, transferring, pledging or assigning the underlying shares, in the event of vesting.

About Stock Compensation Disclosures

Stock-based compensation disclosures detail the equity awards granted to employees and executives — including stock options, restricted stock units (RSUs), and performance shares — along with the valuation methods and assumptions used to expense them. This section reveals the true cost of talent retention and the alignment between management incentives and shareholder interests.

Key signals: total unrecognized compensation expense and its expected recognition period signal future earnings headwinds from already-granted awards. For stock options, examine Black-Scholes assumptions — expected volatility, risk-free rate, and expected term — as understating any of these reduces reported compensation expense. Compare stock compensation expense as a percentage of revenue against peers to assess dilution cost. Watch vesting schedules for acceleration clauses tied to change-of-control events. Performance-based awards with undemanding targets may indicate weak governance. Add back stock compensation to operating cash flow to calculate a more conservative free cash flow figure.
