Janus International Group, Inc.

Adoption of Janus Bonus Program

On March 4, 2026, the Board of Directors adopted the Janus International Group, Inc. Bonus Program (the “Janus Bonus Program”), in order to memorialize the criteria and procedures for bonus opportunities granted to participating employees of the Company and its subsidiaries. The Janus Bonus Program is administered by the Compensation Committee, which generally is authorized to designate eligible employees, establish target bonus opportunities and applicable performance goals, and determine the amounts of any bonuses payable under the Janus Bonus Program; however, the Chief Executive Officer is authorized to designate eligible employees who are not Section 16 officers and establish target bonus opportunities for those employees. Generally, the amount of any bonus earned under the Janus Bonus Program will be based on the level of achievement of the applicable performance goals established by the Compensation Committee for the relevant performance period (the Company’s fiscal year or such other period as determined by the Compensation Committee), but the Compensation Committee retains discretion to adjust the amount of any bonus otherwise earned under the Janus Bonus Program, including adjustments to reflect the Compensation Committee’s assessment of individual employee, business unit or Company-wide performance. Bonuses earned under the Janus Bonus Program generally will be paid by March 15 of the calendar year following the end of the applicable performance period, and except as otherwise specified in a separate written plan or agreement applicable to the employee, each participating employee must remain continuously and actively employed by the Company through the applicable bonus payment date in order to receive a bonus under the Janus Bonus Program. All bonuses under the Janus Bonus Program shall be subject to forfeiture or repayment to the Company to the extent applicable pursuant to the Company’s Clawback Policy as amended from time-to-time (or any successor compensation recovery or clawback policy). The foregoing description of the Janus Bonus Program is a summary only and does not purport to be complete and is qualified in its entirety by reference to the full text of the Janus Bonus Program, a copy of which is filed as Exhibit 10.36 to this Annual Report on Form 10-K and is incorporated herein by reference.
