Stock-Based Compensation

During the three months ended March 31, 2026, the Company granted 76,648 performance shares and 32,850 restricted stock units to certain employees of the Company under the SkyWest, Inc. Amended and Restated 2019 Long-Term Incentive Plan. The performance shares have a three-year vesting period during which the recipient must remain employed with the Company. The number of performance shares awardable from the 2026 grants can range from 0% to 200% of the original amount granted depending on the Company’s performance over three one-year measurement periods against the pre-established targets. The restricted stock units granted in 2026 will vest in three equal installments, with one-third vesting each year on the grant date anniversary. Upon vesting, each performance share and restricted stock unit will be replaced with one share of common stock. The weighted average fair value of these performance shares and restricted stock units on their date of grant was $101.47 per share.

The Company accounts for forfeitures of restricted stock units and performance shares when forfeitures occur. The estimated fair value of the performance shares and restricted stock units is amortized over the applicable vesting periods. Stock-based compensation expense for the performance shares is based on the Company’s anticipated outcome of achieving the performance metrics. During the three months ended March 31, 2026 and 2025, the Company recorded pre-tax stock-based compensation expense of $4.4 million and $4.7 million, respectively.
