Share Conversion from American Depositary Shares to Class A Ordinary Shares

Due to certain historical regulatory policies applicable to U.K. companies, Ensco plc’s shares had been listed on the NYSE as American Depositary Shares (“ADSs”) since the company's redomestication to the U.K. in December 2009.

As a result of recent changes in applicable regulatory policies, the Company’s Board of Directors decided to terminate the ADS facility to allow for Ensco’s Class A Ordinary Shares (“Shares”) to trade directly on the NYSE (The “Conversion”). Ensco's Class A Ordinary Shares began trading on the NYSE on 22 May 2012 under the same symbol “ESV.”.
