Energen Issues Statement in Response to Corvex

BIRMINGHAM, Ala.–(BUSINESS WIRE)–Energen Corporation (NYSE: EGN) (“Energen”) today issued the following
statement regarding the announcement by Corvex Management LP ("Corvex")
that it has submitted four nominees for election to the Company’s Board
of Directors at Energen’s 2018 Annual Meeting of Shareholders:

Energen welcomes open communications with its shareholders and considers
their views seriously. While it is the Company’s policy not to comment
on the content of discussions with specific shareholders, members of
Energen’s Board of Directors and management team have spoken with Corvex
numerous times over the past months.

The Energen Board is made up of nine highly-qualified and experienced
directors, all of whom are independent except for the Chairman. The
Board welcomes fresh perspectives and has added four new independent
directors over the last two years and seven new independent directors
over the last five years. The Company’s Board members are all actively
engaged, have a broad range of valuable perspectives, and possess a
significant experience in the upstream energy space.

Under the leadership of Energen’s Board and management team, Energen’s
transformation into a pure-play Permian Basin oil and gas exploration
and production company culminated in 2016. Throughout 2017, wells
completed with Energen’s new Generation 3 frac design have significantly
outperformed expectations. We are delivering on our drilling and
development plans, driving production growth, and further reducing
costs. We estimate that YOY production growth in 2017 will be more than
34%, and we expect our Generation 3 multi-zone pattern wells to continue
driving production growth as we move forward. At the same time, we
remain focused on continuing to optimize our well performance and
reducing per-unit lease operating and G&A expenses.

Since it first invested in Energen in March 2017, Corvex has pushed a
singularly-focused agenda to sell the Company regardless of market
conditions and the Company’s continued improving performance.

Energen’s Board and management team are committed to acting in the best
interest of the Company and all of our shareholders and will continue to
work to drive growth, enhance returns, and realize the full value of our
assets for all shareholders.

The Energen Board will present its formal recommendation regarding
director nominations in the Company’s definitive proxy materials that
will be filed with the Securities and Exchange Commission and mailed to
shareholders eligible to vote at the 2018 Annual Meeting, which has not
yet been scheduled.

J.P. Morgan and Tudor, Pickering, Holt & Co. are serving as financial
advisors to the Company and Wachtell, Lipton, Rosen & Katz is serving as
its legal advisor.
