HOUSTON, Feb. 16, 2022 /PRNewswire/ -- Summit Midstream Partners, LP (NYSE: SMLP) (the "Partnership", "SMLP" or "Summit") announced today that it will report operating and financial results for the fourth quarter of 2021 on Friday, February 25, 2022, before the start of trading on the New York Stock Exchange, and that it has new business segments for the reporting of its financial results, beginning with its 2021 fourth quarter and annual results.

Fourth Quarter 2021 Earnings Call

SMLP will host a conference call at 10:00 a.m. Eastern on Friday, February 25, 2022, to discuss its quarterly operating and financial results.  Interested parties may participate in the call by dialing 847-585-4405 or toll-free 888-771-4371 and entering the passcode 50277720.  The conference call, live webcast and archive of the call can be accessed through the Investors section of SMLP's website at www.summitmidstream.com.

New Business Segments

SMLP has implemented changes to its reportable segments that better aligns its assets based on their macro-economic drivers and how the business is managed, which enhances commercial, engineering and operational capabilities.  Beginning with its 2021 fourth quarter and annual results, SMLP has five reportable segments that are described below, along with a management categorization of the commodity that has the most influence on customer drilling and completion decisions.

Natural gas price driven: Cash flows in the Northeast, Piceance and Barnett segments are significantly influenced by the price of natural gas because the drilling, completion and recompletion decisions by SMLP's customers in these segments are based on well economics most heavily impacted by the price of natural gas.  Increased upstream activity by customers in these basins therefore result in higher throughput and cash flows for those segments in which we collect fees for gathering natural gas and natural gas liquids.     

• Northeast – Includes our wholly owned midstream assets located in the Utica and Marcellus shale plays and Summit's equity method investment in Ohio Gathering that is focused on the Utica Shale
• Piceance – Includes wholly owned midstream assets located in the Piceance Basin
• Barnett – Includes wholly owned midstream assets located in the Barnett Shale

Oil price driven: Customer activity and cash flows in the Permian and Rockies segments are significantly influenced by the price of oil because the drilling and completion decisions by customers in these segments are based on well economics most heavily impacted by the price of oil.  Decisions to drill and complete wells in these basins therefore result in higher throughput and cash flows for our midstream assets in which SMLP collects fees for gathering or processing hydrocarbons, gathering produced water, or transporting natural gas.

• Permian – Includes wholly owned midstream assets located in the Permian Basin and Summit's equity method investment in the Double E Pipeline
• Rockies – Includes wholly owned midstream assets located in the Williston Basin and the DJ Basin

A comparison of prior and current reportable segments is listed in the table below for illustrative purposes.
