13. Share-Based Payment Arrangements

The Company maintains incentive compensation plans that incorporate share-based payment arrangements for associates and directors. These plans have been approved by the Company's shareholders. Descriptions of these plans were included in Note 19 to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

The Company’s restricted and performance-based share awards to certain employees and directors are subject to service requirements. A summary of the status of the Company’s nonvested restricted stock units and restricted and performance-based share awards at June 30, 2026 are presented in the following table.

At June 30, 2026, there was $67.9 million of total unrecognized compensation expense related to nonvested restricted and performance share awards and units expected to vest in the future. This compensation is expected to be recognized in expense over a weighted average period of 3.2 years. The total fair value of shares that vested during the six months ended June 30, 2026 was $20.7 million.

During the six months ended June 30, 2026, the Company granted 425,386 restricted stock units (RSUs) to certain eligible employees. The holders of unvested RSUs have no rights as a shareholder of the Company, including voting or dividend rights. The Company has elected to award dividend equivalents on each RSU not deferred under the Company's nonqualified deferred compensation plan. Such dividend equivalents are forfeited should the employee terminate employment prior to the vesting of the RSU.

During the six months ended June 30, 2026, the Company granted to key members of executive management 25,278 performance share awards subject to a total shareholder return (“TSR”) performance metric with a grant date fair value of $70.83 per share. The fair value of the performance share units subject to TSR at the grant date was determined using a Monte Carlo simulation method. The number of performance share units subject to TSR that ultimately vest at the end of the three-year performance period, if any, will be based on the relative rank of the Company’s three-year TSR among the TSRs of a peer group of 49 regional banks. The Company also granted 24,535 performance share awards subject to a return on average assets (ROAA) performance metric and 24,535 performance share awards subject to a return on average tangible common equity (ROATCE) performance metric with a grant date fair value of $60.08 per share for both performance share awards. The number of performance shares subject to ROAA and ROATCE that ultimately vest, if any, will be based on the rank of the Company’s three-year ROAA and ROATCE relative to the KBW Regional Bank index. The maximum number of performance share units that could vest is 200% of the target award. Compensation expense for these performance shares is recognized on a straight-line basis over the three-year service period.
