Share Award multiplied by a fraction, the numerator of which is the DTE Energy Pre-Distribution Stock Price, and the denominator of which is the DT Midstream Post-Distribution Stock Price (each such award, a

Plan in 2021 and held as of immediately prior to the Distribution by any Business Employee who will become a DT Midstream Employee shall be converted into a substitute DT Midstream performance share award granted under the DT Midstream Stock Plan (a
“Substitute DT Midstream Performance Share Award”). The target number of DT Midstream Shares that are subject to the Substitute DT Midstream Performance Share Award shall be equal to the target number of DTE Energy Shares subject to
the DTE Energy Performance Share Award held as of immediately prior to the Distribution multiplied by a fraction, the numerator of which is the DTE Energy Pre-Distribution Stock Price and the denominator of
which is the DT Midstream Post-Distribution Stock Price. Each Substitute DT Midstream Performance Share Award shall have substantially the same terms and conditions as the DTE Energy Performance Share Award to which it relates, provided that the
Substitute DT Midstream Performance Share Award shall vest based on the achievement of DT Midstream performance metrics, as established prior to the Distribution, and the holder’s employment with the DT Midstream Group.
