Our Equity Incentive Plan (EIP) provides for the granting of stock-based compensation, including restricted stock unit awards and performance unit awards, to eligible employees and the granting of stock awards to non-employee directors. We have reserved 8.5 million shares of common stock for issuance under the EIP and at Dec. 31, 2024, we had 3.2 million shares available for issuance under the plan. This calculation of available shares reflects shares issued and estimated shares expected to be issued upon vesting of outstanding awards granted under the EIP, excluding estimated forfeitures expected to be returned to the plan.

EnLink Controlling Interest Acquisition - As discussed in Note B, we completed the EnLink Controlling Interest Acquisition on Oct. 15, 2024. EnLink has previously issued restricted incentive units and performance units that vest at the end of a designated period, typically three years. The fair value of these awards attributable to pre-combination service was allocated to consideration transferred and was included as part of the purchase price. The portion attributable to post-combination service is being recognized as compensation expense on a straight-line basis over the remaining vesting period of the awards. Compensation expense for the unit-based awards of EnLink for the ownership period is not material. In addition, unrecognized compensation expense related to the outstanding EnLink restricted incentive units and performance units is not material.

Magellan Acquisition - As discussed in Note B, we completed the Magellan Acquisition on Sept. 25, 2023. Prior to the acquisition, Magellan had previously issued unit-based awards consisting of time-vested phantom units and performance phantom units, that vested at the end of a designated period, typically three years. Pursuant to the terms of the Merger Agreement, each outstanding unit-based award was converted into a restricted stock unit and measured at their acquisition date fair value as if they were vested and issued on the acquisition date. The fair value attributable to pre-combination service was allocated to consideration transferred and was included as part of the purchase price. The portion attributable to post-

combination service is being recognized as compensation expense on a straight-line basis over the remaining vesting period of the awards. Converted restricted stock unit awards accrue dividend equivalents that are paid out in cash at vesting.

Restricted Stock Units - We have granted restricted stock units to key employees that vest at the end of a designated period, typically three years, and entitle the grantee to receive shares of our common stock. Restricted stock unit awards are measured at fair value as if they were vested and issued on the grant date and adjusted for estimated forfeitures. Restricted stock unit awards accrue dividend equivalents in the form of additional restricted stock units prior to vesting. Compensation expense is recognized on a straight-line basis over the vesting period of the award.

Performance Unit Awards - We have granted performance unit awards to key employees that vest at the end of a three-year period. Upon vesting, a holder of outstanding performance units is entitled to receive a number of shares of our common stock equal to a percentage (0% to 200%) of the performance units granted, based on our total shareholder return over the vesting period, compared with the total shareholder return of a peer group of other energy companies over the same period. Performance unit awards are measured at fair value on the grant date based on a Monte Carlo model and adjusted for estimated forfeitures. Performance unit awards accrue dividend equivalents in the form of additional performance units prior to vesting. Compensation expense is recognized on a straight-line basis over the vesting period of the award.

Stock Compensation for Non-Employee Directors - The EIP provides for the granting of nonstatutory stock options and stock bonus awards to non-employee directors, including performance unit awards and restricted stock unit awards. Under the EIP, awards may be granted by the Executive Compensation Committee at any time, until grants have been made for all shares authorized under the EIP. The maximum number of shares of common stock and cash-based awards that can be issued to a participant under the EIP during any year is limited to $0.8 million in value as of the grant date. No performance unit awards or restricted stock unit awards have been made to non-employee directors, and there are no options outstanding.

General - For all awards outstanding, we used a 3% forfeiture rate based on historical forfeitures under our share-based payment plans. We currently use treasury stock to satisfy our share-based payment obligations.

Compensation expense, exclusive of those recognized within transaction costs, for our share-based payment plans was $102 million, $63 million and $53 million during 2024, 2023 and 2022, respectively, before related tax benefits of $36 million, $14 million and $13 million, respectively.

Restricted Stock Unit Activity - As of Dec. 31, 2024, we had $43 million of total unrecognized compensation cost related to our nonvested restricted stock unit awards, which is expected to be recognized over a weighted-average period of 1.7 years. The following tables set forth activity and various statistics for our restricted stock unit awards:

Employee Stock Purchase Plan - We have reserved a total of 12 million shares of common stock for issuance under our Employee Stock Purchase Plan (the ESPP). Subject to certain exclusions, all employees are eligible to participate in the ESPP. Employees can choose to have up to 10% of their base pay withheld from each paycheck during the offering period to purchase our common stock, subject to terms and limitations of the plan. The purchase price of the stock is 85% of the lower of its grant date or exercise date market price. Approximately 59%, 69% and 68% of employees participated in the plan in 2024, 2023 and 2022, respectively. Under the plan, we sold 275,874 shares at a weighted average of $64.38 per share in 2024, 236,108 shares at a weighted average of $52.70 per share in 2023 and 235,583 shares at a weighted average of $47.21 per share in 2022.

Employee Stock Award Program - Under our Employee Stock Award Program, we issued, for no monetary consideration, to all eligible employees one share of our common stock when the per-share closing price of our common stock on the NYSE is at or above each one-dollar increment above its previous high closing price. We originally reserved a total of 900,000 shares of common stock for issuance under this program. Shares issued to employees under this program during 2024 totaled 127,825 and we have fully awarded all shares allocated to the program. We expect to request additional shares be issued and allocated to the program during the 2025 Annual Meeting of Shareholders. Employees have received awards through the $103 milestone. No shares were issued to employees under this program in 2023 or 2022.

Deferred Compensation Plan for Non-Employee Directors - Our Deferred Compensation Plan for Non-Employee Directors provides our non-employee directors the option to defer all or a portion of their compensation for their service on our Board of Directors. Under the plan, directors may elect either a cash deferral option or a phantom stock option. Under the cash deferral option, directors may elect to defer the receipt of all or a portion of their annual retainer fees, which will be credited with interest during the deferral period. Under the phantom stock option, directors may defer all or a portion of their annual retainer fees and receive such fees on a deferred basis in the form of shares of common stock under our EIP, which earn the equivalent of dividends declared on our common stock. Shares are distributed to non-employee directors at the fair market value of our common stock at the date of distribution.
