Sinclair is pleased to provide the latest, most beneficial personal savings and retirement programs available; a Pre-tax 401(k) Plan and a Roth 401(k) Plan! The plans are administered by Empower Retirement.

Employee Pre-Tax and Roth 401(k):

All employees are eligible on the 1^st day of the month following 30 days of employment. If no investment selection is made, all contributions will default to the age-appropriate Empower Retirement Target Date Fund. To make changes to the deferral rate or opt out of the plan visit empowermyretirement.com. Though all employees that have met the service requirement are eligible to enroll in the 401(k) program, only employees who have completed one year of service to the Company will be eligible for the company match benefit.

Participating employees can contribute up to 85% of their eligible compensation on a pre-tax or post-tax basis. The IRS limit for 2025 is $23,500 (under age 50). Employees 50 and older by 12/31 of the plan year are eligible to make additional catch-up contributions. See chart below for eligible contribution limits.

Participating employees can contribute up to 85% of their eligible compensation. Employees aged 50 and over by 12/31 in the 2026 calendar year are eligible to make additional catch-up contributions. Employees who are age 50 or older AND earned more than $150,000 in wages (as shown in Box 3 of your 2025 W-2) will have their 401(k) catch-up contributions automatically made as Roth (after-tax) contributions. See chart below for eligible contribution limits. Set up your deferral percentage with these annual limits in mind. There is no separate election to participate in the catch-up, it will automatically begin once the IRS limit is met, if you meet the age requirements.

The Sinclair 401(k) Retirement Plan allows employees the option of making both Pre-tax and Roth contributions to your 401(k). Choose a deferral source that provides you with financial flexibility to prepare for your retirement goals.

Pre-Tax	Roth
Lower your current taxable income	Pay taxes on contributions now
Any earnings grow tax-deferred	Any earnings grow tax-deferred
Distributions are taxed as regular income	Qualified distributions are tax-free

The Sinclair 401(k) plan has a Safe Harbor Match. With the Safe Harbor Match, Sinclair will match 100% of the first 3% of contributions you make plus 50% up to the next 2%. The Safe Harbor Match contribution will be based on the annual total deferral percentage (including both pre-tax and post tax contributions). The maximum match is 4% if you contribute 5% or greater. All matching contributions are 100% vested immediately. The Sinclair Safe Harbor Matching contribution is deposited on a pre-tax basis. Examples of the match calculation:

Employee Deferral	Company Match
3%	3%
4%	3.5%
5%	4%
6%	4%

The match is made in March of the following year in Sinclair Stock, which can be moved at any time to other investment options.

Withdrawals:

If you leave for any reason (including retirement after age 65), you may withdraw your vested account balance. While you are still employed you may make limited withdrawals from your account if you experience a severe financial hardship (as defined by the IRS) or are age 59 1/2 or older.

Note: This summary of benefits is not meant to be a substitute for a thorough reading of the Summary Plan Description. The provisions of the 401(k) plan are very complex it is not possible to fully explain all aspects of the plan in these short questions and answers. You should always consult the summary plan description if you have any questions about the plan if after reading the Summary Plan Description, you still have questions, you should contact the plan administrator.
