Hess Midstream Partners Announces Strategic Joint Venture to Build New Gas Processing Plant in North Dakota

HOUSTON–(BUSINESS WIRE)–$HESM–Hess Midstream Partners LP (NYSE:HESM) (“Hess Midstream”) announced
today the formation of a 50/50 joint venture with Targa Resources Corp.
(NYSE:TRGP) (“Targa”) to construct a new 200 million standard cubic feet
per day gas processing plant called Little Missouri Four (“LM4”). The
new gas plant will be located at Targa’s existing Little Missouri
facility, south of the Missouri River in McKenzie County, North Dakota.

Targa will manage the construction of LM4 and will operate the plant.
Hess Midstream’s 50 percent interest in the joint venture will be held
through Hess TGP Operations LP, in which Hess Midstream owns a 20
percent controlling economic interest, and Hess Infrastructure Partners
LP (“HIP”) owns the remaining 80 percent economic interest. LM4 is
expected to be completed in the fourth quarter of 2018.

John Gatling, Chief Operating Officer of Hess Midstream said, “The
Little Missouri Four Gas Processing Plant demonstrates our commitment to
executing our strategy by providing additional Bakken basin processing
capacity, which provides another layer of organic growth to meet our
long-term targeted annual distribution per unit growth. By executing
infrastructure projects that provide more optionality to producers, Hess
Midstream expects to continue to capture additional Hess and third-party
volumes, reinforcing the competitive advantage we enjoy from our
strategically located infrastructure in the core of the Bakken."

Doug Burgum, Governor of North Dakota said, “We are thrilled to welcome
Hess’ significant investment, which underscores the company’s
longstanding presence in North Dakota and commitment to our state. This
processing plant will provide much-needed capacity at a time when North
Dakota’s oil production nears record levels and associated natural gas
production continues to climb. It’s a huge step in the right direction
toward continuing to meet our flaring reduction goals and encouraging
responsible energy development and infrastructure investment.”

Jonathan Stein, Hess Midstream’s Chief Financial Officer said, “The
joint venture with Targa and related investments are expected to be
fully integrated into our existing contract structure. This reinforces
the competitive advantage we have through our long-term contracts with
Hess Corporation, which are 100 percent fee-based and designed to
deliver stable and growing cash flows while providing downside
protection. This strategic investment is expected to continue to enhance
Hess Midstream’s organic growth trajectory with limited use of our
balance sheet, while further increasing our dropdown timing flexibility.”

Construction costs for LM4 are anticipated to be approximately $150
million (gross to the joint venture), with $15 million attributable to
Hess Midstream ($60 million funded by HIP). In addition, Hess Midstream
and HIP will also invest approximately $100 million gross, $20 million
attributable to Hess Midstream, for new pipeline infrastructure to
gather volumes to the LM4 plant.

With these investments, Hess Midstream will have total processing
capacity of 350 million standard cubic feet per day of gas in the
Bakken, with export optionality north and south of the Missouri river.
Hess Midstream retains the option to further expand processing capacity
by de-bottlenecking the Tioga Gas Plant in the future and, as a
result, the previously planned turnaround at the Tioga Gas Plant in 2019
is expected to be deferred.
