Stockholders' Equity Note [Abstract] |
Stockholders' Equity | Note 12 — Stockholders’ Equity Incentive Plan The Company maintains an Amended and Restated Omnibus Equity Incentive Plan (the “Equity Plan”). The Equity Plan allows for awards of stock options, stock appreciation rights, restricted stock, RSUs, and other stock- and cash-based awards, including awards that are subject to service-based and performance-based vesting conditions. As of December 29, 2023, the Company had outstanding grants of stock options, restricted stock awards, RSUs and PSUs. Stock options granted under the Equity Plan are granted at fair market value on the date of grant, become exercisable generally over a three-year period, or as determined by the Board, and expire over periods not exceeding 10 years from the date of grant. Certain stock options and stock-based awards provide for accelerated vesting if there is a change in control and pre-established financial metrics are met (as defined in the Equity Plan). Grants of restricted stock outstanding under the Equity Plan generally vest over periods of one to three years. Grants of RSUs and PSUs outstanding under the Equity Plan generally vest based on service, performance, or a combination of both. On June 15, 2023, the Company’s stockholders approved a proposal to increase the number of shares that may be issued pursuant to stock-based awards granted under the Equity Plan, which increased the share pool by 2,170,000 shares, for a total of 20,205,000 shares. As of December 29, 2023, there were 2,993,717 shares available for grants of stock-based awards under the Equity Plan.

Note 12 — Stockholders’ Equity (Continued) Stock-Based Compensation (Continued) As of December 29, 2023, total unrecognized compensation cost related to non-vested stock-based compensation arrangements granted under the Equity Plan were as follows (in thousands):
|  | 2023 |
Stock options |  | $ | 22,001 |
Restricted stock, RSUs and PSUs |  |  | 16,952 |
Total unrecognized stock-based compensation cost |  | $ | 38,953 |
This cost is expected to be recognized over a weighted-average period of approximately two years. Assumptions The fair value of each stock option award is estimated on the date of grant using a Black-Scholes option valuation model applying the weighted-average assumptions noted in the following table. Expected volatilities are based on historical volatility of the Company’s stock. The expected term of stock options granted is derived from the historical exercises and post-vesting cancellations, and represents the period of time that stock options granted are expected to be outstanding. The Company has calculated a 7% estimated forfeiture rate based on historical forfeiture experience. The risk-free rate is based on the U.S. Treasury yield curve corresponding to the expected term at the time of the grant.
