Enable Midstream Signs Definitive Agreement to Acquire Align Midstream

OKLAHOMA CITY–(BUSINESS WIRE)–Enable Midstream Partners, LP (NYSE: ENBL) today announced it has
entered into a definitive agreement to acquire Align Midstream, LLC,
which owns natural gas gathering and processing assets in the Cotton
Valley and Haynesville plays of the Ark-La-Tex Basin, for approximately
$300 million, subject to certain customary adjustments. This strategic
acquisition extends Enable’s footprint in areas with increasing producer
activity and is expected to be accretive to Enable’s 2018 distributable
cash flow per unit.

Align operates approximately 190 miles of natural gas gathering
pipelines across Rusk, Panola and Shelby counties in Texas and DeSoto
Parish in Louisiana and a cryogenic natural gas processing plant in
Panola, Texas, with a capacity of 100 million cubic feet per day.
Align’s assets are underpinned with long-term, fee-based contracts,
including approximately 100,000 gross acres of dedication from producer
customers.

“This transaction complements Enable’s midstream platform in the
Ark-La-Tex Basin, and we are well-positioned to integrate and optimize
these assets,” said Enable Midstream President and CEO Rod Sailor. “We
are excited about the outlook for the Cotton Valley and Haynesville, and
this acquisition further builds out our footprint to capture
opportunities in active areas of these plays.”

The acquisition is incremental to Enable’s 2017 expansion capital
outlook, and Enable does not expect to access the capital markets in
2017 as a result of this transaction. The transaction is subject to
customary regulatory approval and closing conditions and is expected to
close as soon as practicable after such approvals and conditions have
been satisfied.
