 LTI grants.

#### Column (i)
This column reflects the aggregate grant date fair value of the PSUs and PRSUs granted in 2024.

4 The value of the PSUs related to TSR is based on the probable outcome of the performance conditions as of the grant date using a Monte Carlo simulation model ($80.57 for January 31, 2024 grant). The value of the PSUs related to ROE is based on the closing price of common stock on the grant date ($69.52 for January 31, 2024 grant).

4 For the PSUs related to the GHG reduction metric for Mr. Womack, Mr. Tucker and Mr. Connally, the value of these shares is based on the closing price of the common stock on the grant date ($69.52 for January 31, 2024 grant).

4 The value of the PRSUs is based on the closing price of common stock on the grant date ($69.52). The assumptions used in calculating these amounts are discussed in Note 12 to the financial statements included in the 2024 annual report.
