Plains All American Provides Details on Management Succession Plan and Transition Process

HOUSTON–(BUSINESS WIRE)–Plains All American Pipeline, L.P. (NYSE: PAA)
and Plains GP Holdings (NYSE: PAGP)
today provided details regarding its management succession plan and
transition process. Greg Armstrong has informed the Board of Directors
of his plans to retire as Chief Executive Officer (CEO) at the end of
2018. Under the plan approved by Plains’ Board, Willie Chiang, PAA’s
current Executive Vice President and Chief Operating Officer – U.S.,
will become CEO upon Armstrong’s retirement and Armstrong will continue
as non-executive Chairman of the Board of Directors through December
2019, at which time he will retire from the Board. Harry Pefanis will
continue as President and a Director.

Armstrong has been with PAA and its predecessor organizations since
1981. “It has been an honor and a privilege to work at Plains for over
36 years and to serve the last 25 years as CEO,” Armstrong said. “PAA
has grown significantly in both size and profitability over that time
period. Those accomplishments were made possible through the commitment
and solid performance of our employees working together as a team and
the unwavering support and thoughtful guidance provided by our Board of
Directors and key financial partners. I consider myself very fortunate
to have been a part of this team.”

“The plans announced today reflect several years of thoughtful
preparation and succession planning, which we view as a process versus
an event at a point in time. Over the last two years, Willie, Harry and
I have been working together to ensure a seamless transition. As the
next step in this transition process, Willie’s role as Chief Operating
Officer will be expanded to cover both the U.S. and Canada, and Harry
will take on the newly created role of Chief Commercial Officer. The
succession process will continue over the next year or so as the three
of us work together to facilitate a seamless transition. I am pleased
that Willie will become our next CEO, and I have every confidence that
Willie, Harry and the rest of PAA’s leadership team will continue to
build upon PAA’s success.”

Chiang joined PAA in 2015 as PAA’s Executive Vice President and Chief
Operating Officer – U.S., and was appointed to the Board of Directors in
February 2017. He has more than 30 years of energy industry experience,
having served in a number of executive leadership roles within large,
complex organizations like PAA. Prior to joining PAA, Chiang held the
positions of Executive Vice President, Operations at Occidental
Petroleum, and Senior Vice President of Refining, Marketing,
Transportation and Commercial for ConocoPhillips.

“I am honored to be named as Greg’s successor,” Chiang said. “Alongside
our executive team, Board of Directors and employees, I am committed to
continuing PAA’s growth and success as a leading midstream energy
company.”
