EQUITY INCENTIVE PLAN
The Company’s equity incentive plan provides employees and directors of the Company additional incentives to join and/or remain in the service of the Company as well as to maintain and enhance the long-term performance and profitability of the Company. The Company’s 2013 Equity Incentive Plan was approved by shareholders on May 2, 2013 and provides that 2 million shares of common stock, plus any shares that remained available for grant under the Company’s prior equity incentive plan as well as options outstanding that terminate without being exercised, may be the subject of awards. The plan provides for the grant of options, restricted stock units, and other equity-based awards. The exercise price of options granted shall not be less than the fair market value of the common stock on the date of the award. Options primarily vest equally over a five-year period from the date of grant and have a maximum term of up to 10 years. Performance share units generally vest after a three-year period from the date of the grant based upon satisfaction of the performance condition. Restricted share units primarily vest from the date of the grant equally over a three-year period for executive officers and a five-year period for participating managers. During 2025, the compensation committee of the Board of Directors generally granted restricted share units to participating managers and a combination of non-qualified stock options, performance share units and restricted share units to executive officers.
On May 6, 2021, the Company's shareholders approved the adoption of the Company's 2013 Equity Incentive Plan (Amended and Restated), with the effect that approximately 0.9 million additional shares of common stock were added to the 2.1 million shares that remained available under the plan prior to its amendment. In addition, shares subject to options granted under the Company's prior equity incentive plan that terminate or are forfeited without being exercised are also available for awards under the amended plan. The amended plan expires in 2031.
All share-based compensation arrangements granted to employees, including stock option grants, are recognized in the consolidated statement of operations based on the grant-date fair value of the award over the period during which an employee is required to provide service in exchange for the award. Share-
based compensation expense is recorded within selling, general, and administrative in the consolidated statement of operations with a corresponding offset to additional paid-in capital in the consolidated balance sheet.
The fair values of stock options granted were calculated using the Black-Scholes pricing model. The aggregate intrinsic value of an option is the amount by which the fair value of the underlying stock exceeds its exercise price.

As of the date granted, the weighted average grant-date fair value of the options granted during the years ended December 31, 2025, 2024, and 2023 was $502.65, $494.81, and $400.30, respectively.
Such weighted average grant-date fair value was determined using the following assumptions:

Expected volatility29%28%27%

The total intrinsic value of options exercised during the years ended December 31, 2025, 2024, and 2023 was approximately $32.7 million, $62.9 million, and $68.7 million, respectively.
In November 2023, the Company also granted 7,137 performance options with a grant-date fair value of $2.9 million upon achievement of the performance target. The performance target is based on the Company’s cumulative average local currency sales growth rate over the four-year period ending December 31, 2027. If the performance target is met, the performance options cliff vest at the conclusion of the four-year period and will settle based upon actual performance ranging from zero to 150% of the
target. Compensation expense is recognized over the four-year period based on the estimated actual performance relative to the target.
The compensation expense for options recognized during the years ended December 31, 2025, 2024, and 2023 was $8.1 million, $8.4 million, and $6.0 million, respectively.

The weighted average grant-date fair value of the restricted stock units granted during the years ended 2025, 2024, and 2023 was $1,388.27, $1,260.96, and $1,029.48 per unit, respectively, which primarily vest ratably over a five-year period. The total fair value of the restricted stock units on the date of grant was $17.3 million for 2025, $12.2 million for 2024, and $12.8 million for 2023 and will be recorded as compensation expense on a straight-line basis over the vesting period. The total fair value of restricted stock units vested during the years ended December 31, 2025, 2024, and 2023 was approximately $9.9 million, $8.7 million, and $8.6 million, respectively. The compensation expense of $10.7 million, $8.3 million, and $8.8 million was recognized during the years ended December 31, 2025, 2024, and 2023, respectively.
The Company granted performance share units with a market condition during 2025, 2024, and 2023. Grantees of performance share units will be eligible to receive shares of the Company’s common stock depending upon the Company’s total shareholder return relative to the performance of companies in the S&P 500 Health Care and S&P 500 Industrials over a three-year period. The awards actually earned will range from zero to 200% of the targeted number of performance share units for the three-year performance period and will be paid, to the extent earned, in the fiscal quarter following the end of the applicable three-year performance period. During 2025, the market conditions for the 2022 performance share units were substantially not met. Performance share unit awards were valued using a Monte Carlo simulation based on the following assumptions:

Expected life in years333

The weighted average grant-date fair value of the performance share units granted was $1,468.24 for 2025, $1,153.99 for 2024, and $1,103.23 for 2023. The total fair value of the performance share units on the date of the grant was $4.1 million, $3.6 million, and $3.3 million for 2025, 2024, and 2023,
respectively, and will be recorded as compensation expense on a straight-line basis over the three-year performance period.
The compensation expense for performance share units recognized during the years ended December 31, 2025, 2024, and 2023 was $3.7 million, $3.3 million, and $3.1 million, respectively.
At December 31, 2025, a total of 2,810,038 shares of common stock were available for grant in the form of stock options, restricted stock units, or performance share units.
As of December 31, 2025, the unrecorded deferred share-based compensation balance related to stock options, restricted stock units, and performance share units was $59.3 million and will be recognized using a straight-line method over an estimated weighted average amortization period of 2.2 years.

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.
