Filing's footnotes

1. The reported transaction reflects the payout of 241,636 performance stock units ("PSUs") granted to Mr. Boone in 2023, which were subject to a three-year cliff vesting period and performance conditions based 25% on absolute stock price performance and 75% on absolute ROIC performance. On March 3, 2026, the Compensation Committee determined that the applicable performance conditions were achieved at target, resulting in full payout and vesting of the 241,636 PSUs in the form of shares of common stock.

2. Reflects a reduction of shares withheld to cover taxes payable by the reporting person due to the March 3, 2026, vesting and payout of performance stock units granted in 2023.

3. This grant of restricted shares is scheduled to vest ratably on April 1, 2027, April 1, 2028 and April 1, 2029.
