About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

F1 · derivative.exercise_price: Each phantom unit is the economic equivalent of one common unit.

F2 · kind: The phantom units have been awarded in connection with a compensation agreement approved by the Compensation Committee of the Board of Directors of Summit Midstream GP, LLC (the "Company") on November 29, 2022, permitting executive officers, to forfeit none, 50% or 100% of each vesting tranche of his or her outstanding retention cash component awards granted in each of 2020, 2021 and 2022 in exchange for phantom units to be granted under the Summit Midstream Partners, LP 2022 Long-Term Incentive Plan (the "Plan").

F6 · price: The price for each Phantom Unit was calculated from the volume weighted average price of a common unit of the Company during the three trading days ending on and including the date of grant.

F3 · derivative.exercise_date: The phantom units (rounded down to the nearest whole number of units, except in the case of the final vesting date) shall vest on March 15, 2024, subject to continued employment and accelerated vesting as provided in the applicable award agreement. The Reporting Person will receive distribution equivalent rights ("DERs") for each phantom unit, providing for payment on the vesting date of a lump sum of cash equal to the accrued distributions from and after the grant date of the phantom units.

F4 · derivative.expiration_date: The phantom units and associated DERs do not expire. The phantom units are settled upon vesting in common units (on a one-for-one basis) or in cash, at the discretion of the Issuer.

F5 · derivative.underlying_shares: The corresponding number of Phantom Units granted pursuant to the Plan was determined by dividing the cash value of the applicable vesting tranche of the cash retention component award forfeited by such participant by the volume weighted average price of a common unit of the Company during the three trading days ending on and including the date of grant. Due to an oversubscription of the phantom units, the Reporting Person received only 98.54% of the phantom units elected.
