  Ensco CEO Dan Rabun to Retire

    Will Continue in Current Role Until CEO Succession Has Been Completed

Business Wire

LONDON -- November 13, 2013

Ensco plc (NYSE: ESV) announced today that Chairman, President and CEO Dan
Rabun has decided to retire after nearly eight years of service. Mr. Rabun
will continue to serve in his current role as Chairman, President and CEO
until the Board of Directors has completed the succession process and a new
CEO has been appointed. To assist with the new CEO’s transition, Mr. Rabun
will remain Chairman through at least the 2014 Annual General Meeting.

Mr. Rabun’s planned retirement from the CEO role has been part of the Board’s
succession planning process for more than a year. A special committee chaired
by Paul Rowsey, the Board’s Lead Director, is directing the succession
process. This committee has been working with Heidrick & Struggles
International Inc., a leading executive recruiting firm, and is considering
both external and internal candidates.

“Dan has made many contributions to the success of our Company - especially
his unwavering passion to further advance safety and operational excellence,”
said Mr. Rowsey. “Over the past eight years revenue and stockholders’ equity
have more than quadrupled, dividends have grown from $0.10 to $3.00 per share
annually and we are now among the largest and most well-respected offshore
drillers.”

Mr. Rowsey concluded, “We are grateful that Dan will facilitate a smooth
transition as we complete the succession process.”

Mr. Rabun commented, “I have truly enjoyed leading Ensco over the past eight
years. We have a highly-talented management team and exceptionally dedicated
employees who have made our many achievements possible. In particular, I am
especially proud that we have taken our safety performance to an even higher
level. Our new CEO will benefit, as I have, from our employees’ commitment to
go beyond expectations in everything they do.”
