EMPLOYEE STOCK PLANS

Employee Stock Plans

The Company grants stock awards in the form of restricted stock units (“RSUs”) and performance stock units (“PSUs”) to its employees as part of the Company’s long-term equity compensation plan. These stock awards are granted to employees with a unit purchase price of zero dollars and typically vest over three years, subject to the employee’s continued service with the Company and, in the case of PSUs, subject to achieving certain performance goals and market conditions. The Company also grants common stock to its board members in the form of restricted stock awards (“RSAs”), which vest on the earlier of the next Annual Shareholder Meeting, or 365 days from date of grant. The aggregate number of shares authorized for issuance under the plan is 1.3 million.

Stock-based compensation expense includes compensation costs related to estimated fair values of awards granted. The estimated fair value of the Company’s equity-based awards is amortized on a straight-line basis over the awards’ vesting period and is adjusted for performance as it relates to PSUs.

The following table shows the Company’s stock-based compensation expense included in the Condensed Consolidated Statements of Operations:

For the three and six months ended June 27, 2025, 0.7 million and 0.8 million RSUs were granted with a weighted average fair value of $22.12 and $22.35 per share, respectively. For the three and six months ended June 28, 2024, 451 thousand and 475 thousand RSUs were granted with a weighted average fair value of $41.32 and $41.47 per share, respectively.

For the three and six months ended June 27, 2025, 98 thousand PSUs were granted with fair value of $2.2 million, while 125 thousand PSUs were granted for the three and six months ended June 28, 2024, with a fair value of $5.8 million.

The following table summarizes the Company’s combined RSU, PSU and RSA activity for the six months ended June 27, 2025:


(In millions)	Number of Shares	Aggregate Intrinsic Value
Outstanding at December 27, 2024	1.4	$	52.0
Granted	0.9
Vested	(0.4)
Forfeited	(0.3)
Outstanding at June 27, 2025	1.6	$	35.3
Expected to vest at June 27, 2025	1.5	$	35.1

As of June 27, 2025, approximately $36.0 million of unrecognized stock-based compensation cost related to employee and director awards remains to be amortized on a straight-line basis over a weighted average period of 2.1 years, and will be adjusted for subsequent changes in future grants.

Under the current PSU program, performance goals are set at the time of grant and performance is reviewed at the end of a three-year period. The percentage to be applied to each participant’s target award ranges from zero to 200%, based upon the extent to which the financial performance goals are achieved. If specific performance threshold levels for the financial

goals are met on an annual basis, the amount earned for that element will be applied to one-third of the participant’s PSU award granted to determine the number of total units earned.

Recipients of PSU awards generally must remain employed by the Company on a continuous basis through the end of the three-year performance period in order to receive any amount of the PSUs covered by that award. In events such as death, disability or retirement, the recipient may be entitled to pro-rata amounts of PSUs as defined in the Plan. Target shares subject to PSU awards do not have voting rights of common stock until earned and issued following the end of the three-year performance period.

Employee Stock Purchase Plan

The ESPP permits employees to purchase common stock at a discount through payroll withholdings at certain specified dates (purchase period) within a defined offering period. The purchase price is 85% of the fair market value of the common stock at the end of the purchase period and is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. The aggregate number of shares authorized for issuance under the plan is 1.1 million.

During the three and six months ended June 27, 2025. 72 thousand shares were issued under the ESPP. The Company recorded $0.2 million and $0.4 million of expense related to ESPP for the three and six months ended June 27, 2025

During the three and six months ended June 28, 2024, 42 thousand shares were issued under the ESPP. The Company recorded $0.2 million and $0.3 million of expense related to ESPP for the three and six months ended June 28, 2024.
