Your incentive payment will be based on performance measures approved by the Management Development and Compensation Committee and may be subject to adjustments based on your individual performance. You must be an active employee with AWI on the day of incentive distribution, which is typically paid out in March following the plan year.

You will be eligible for long-term incentive (LTI) plan participation which is typically made in the form of stock-based grants, targeted to have a value of 100% of your annualized base salary. You will be considered for participation at the time of the next grant in 2025.

We are also offering you a one-time sign-on bonus in the gross amount of $50,000, which will be paid in your normal pay cycle after your first 30 days of employment. Should you

voluntarily terminate or are terminated for Cause within twelve months of your first day of employment, you agree to repay this sign-on bonus.
