Stock-Based Compensation
We grant various types of stock-based compensation awards to directors, officers and key employees under our 2016 incentive plan. These awards have included stock options, restricted stock, restricted stock units, performance-based units, cash incentive awards and other equity-related awards (collectively, “Awards”).
The 2016 incentive plan authorizes the issuance of up to 11.4 million shares of our common stock as Awards. The 2016 incentive plan will terminate on May 18, 2032, unless terminated earlier by our Board of Directors. As of December 31, 2025, approximately 2.6 million shares of our common stock were available for the grant of Awards under the 2016 incentive plan.
Our stock-based compensation expense is recorded in Salaries, wages and employee benefits, Transaction and integration costs or Restructuring costs on our Consolidated Statements of Income:

Restricted Stock Units and Performance-Based Restricted Stock Units
We grant RSUs and PSUs to our key employees, officers and directors with various vesting requirements. RSUs generally vest based on the passage of time (service conditions) and PSUs generally vest based on the achievement of our financial targets (performance conditions). PSUs may also be subject to stock price (market conditions), employment and other non-financial conditions. The holders of the RSUs and PSUs do not have the rights of a stockholder and do not have voting rights until the shares are issued and delivered in settlement of the awards.
Upon vesting, we generally withhold a portion of the shares of our common stock to satisfy the employee’s minimum tax withholdings. Cash paid for tax withholdings is reflected in financing activities on our Consolidated Statements of Cash Flows.
We estimate the fair value of PSUs subject to market-based vesting conditions using a Monte Carlo simulation lattice model, utilizing several key assumptions, including expected Company and peer company share price volatility, correlation coefficients between peers and the Company, the risk-free rate of return and other award design features. For 2025 PSU grants, we assumed share price volatility of 47.58% and a risk-free rate of return of 3.89%.

Employee Stock Purchase Plan
During the first quarter of 2023, the Compensation and Human Capital Committee of the Board of Directors approved the suspension of our previous employee stock purchase plan, effective after the completion of the March 2023 offering period. There was no stock-based compensation expense recognized under this plan as it was non-compensatory.
During 2024, the Compensation and Human Capital Committee of the Board of Directors approved the reinstatement of our employee stock purchase plan, with the first offering period commencing on December 1, 2024. Our current employee stock purchase plan offers eligible employees, excluding our executive officers and directors, the right to purchase our common stock using up to 10% of each employee’s compensation. Shares are purchased at 10% below fair market value on the last trading day of each six-month offering period. The plan authorized the purchase of up to five million shares of our common stock, which is incremental to the shares authorized under the 2016 incentive plan as discussed above. The plan will terminate in October 2027, unless terminated earlier by our Board of Directors. We recognize stock-based compensation expense related to the plan over the offering period as the plan is compensatory. Compensation expense related to the plan was immaterial in 2025 and 2024. At December 31, 2025 and 2024, approximately four million shares of our common stock were available for purchase under the plan.
