STOCK-BASED COMPENSATION AND DEFINED CONTRIBUTION PLANS
The DT Midstream, Inc. Long-Term Incentive Plan permits the grant of incentive and nonqualified stock options, stock appreciation rights, restricted stock awards and restricted stock units, performance share awards, and performance units to employees, consultants and members of DT Midstream's Board of Directors. As a result of a restricted stock award grant, restricted stock unit or performance share award settlement, or by exercise of a stock option, we may issue common stock from our authorized but unissued common stock and/or from outstanding common stock acquired by or on behalf of DT Midstream in the participant's name. Key provisions of the DT Midstream Plan are:
•Authorized limit as of December 31, 2025 was 10,000,000 shares of common stock. The authorized limit increases annually on January 1 by the lesser of 1,750,000 shares of common stock or the amount determined by the DT Midstream Board of Directors.
•Prohibits the grant of a stock option with an exercise price that is less than the fair market value of DT Midstream's stock on the grant date.

Restricted Stock Units
Restricted stock units granted under the DT Midstream Plan are for a specified number of shares of DT Midstream common stock that entitle the holder to receive common stock, a cash payment, or a combination thereof at the end of the specified vesting period, which is generally three or four years. Restricted stock units are deemed to be equity awards. The fair value of restricted stock units is based on DT Midstream's closing common stock price on the grant date. The fair value is amortized to stock-based compensation expense using a graded vesting schedule over the vesting period. Restricted stock units are settled with DT Midstream common stock and fractional shares are settled in cash.
During the vesting period, the number of restricted stock units granted will increase, assuming full dividend reinvestment on each dividend payment date. The recipient of a restricted stock unit has no shareholder rights during the vesting period. Restricted stock units are nontransferable and subject to risk of forfeiture during the vesting period. Forfeitures are recognized in the period they occur.

Performance Share Awards
Performance share awards granted under the DT Midstream Plan are for a specified number of shares of DT Midstream common stock that entitle the holder to receive common stock, a cash payment, or a combination thereof at the end of the specified vesting period, which is generally three years. Performance share awards are deemed to be equity awards. Performance share stock-based compensation expense is accrued over the vesting period based on the grant date fair value calculated using: (i) DT Midstream's closing common stock price on the grant date; (ii) the grant date fair value of the market condition; and (iii) the probable achievement of performance objectives. The number of shares issued at settlement is determined based on market conditions and the achievement of certain DT Midstream performance objectives. Performance share awards are settled with DT Midstream common stock and fractional shares are settled in cash.
During the vesting period, the number of performance share awards granted will increase, assuming full dividend reinvestment on each dividend payment date. The recipient of a performance share award has no shareholder rights during the vesting period. Performance share awards are nontransferable and are subject to risk of forfeiture during the vesting period. Forfeitures are recognized in the period they occur.
