Note 16. Stock-Based Compensation

The Company measures compensation expense for all stock-based awards based on the estimated fair values on the date of the grant. Stock options generally vest ratably over three years from the date of grant, subject to the recipient’s continued service over such period, and expire 10 years from the date of grant. RSUs generally vest ratably over three years from the date of grant, subject to the recipient’s continued service over such period, and contain no other service or performance conditions. PSUs vest at the end of a three-year period based on the achievement of certain Company performance metrics and the recipient’s continued service over such period. The Company’s policy is to recognize stock-based compensation expense on a straight-line basis over the requisite service or vesting period. For awards that are contingent upon performance metrics, the probability of achievement is taken into account in the calculation of the expense to be recognized and modified as needed. Forfeitures for stock options and restricted stock awards, including RSUs and PSUs, are recognized as they occur.

Stock Option Activity

The fair value of stock options vested during the 13-week periods ended September 28, 2025 and September 29, 2024 was $12 and $1,065, respectively. The fair value of stock options vested during the 39-week periods ended September 28, 2025 and September 29, 2024 was $979 and $2,965, respectively. As of September 28, 2025, total unrecognized stock-based compensation expense related to unvested stock options was $349, which is expected to be recognized over a weighted-average period of 0.48 years.

Restricted Stock Unit Activity

The fair value of RSU shares vested during the 13-week periods ended September 28, 2025 and September 29, 2024 was $119 and $75, respectively. The fair value of RSU shares vested during the 39-week periods ended September 28, 2025 and September 29, 2024 was $5,624 and $3,655, respectively. As of September 28, 2025, total unrecognized stock-based compensation expense related to the Company’s unvested RSU activity was $12,254, which is expected to be recognized over a weighted-average period of 2.00 years.

Performance Stock Unit Activity

In fiscal 2024 and 2025, the Company granted PSUs to certain of its officers and employees. These PSUs vest at the end of a three-year period based upon the level of achievement of certain Company performance metrics and the recipient’s continued service over such period. The number of shares that can be earned will range from 0% to 200% of the granted PSUs, based upon the Company’s level of achievement of the stated performance metrics. The number of PSUs expected to vest and for which compensation cost has been recognized is based on the number of awards that the Company believes are probable to vest as of September 28, 2025.

The fair value of PSU shares vested during the 13-week and 39-week periods ended September 28, 2025 and September 29, 2024 was $0, as no shares have vested as of such periods. As of September 28, 2025, total unrecognized stock-based compensation expense related to the Company’s unvested PSU activity was $8,401, which is expected to be recognized over a weighted-average period of 1.87 years.
