Ensco plc (NYSE: ESV) announced today that its Board of Directors has declared a regular quarterly cash dividend of US$0.50 per Class A ordinary share payable on 22 March 2013 to holders of Ensco’s shares as of the 11 March 2013 record date. The prior quarterly dividend was $0.375 per share. Chairman, President and Chief Executive Officer Dan Rabun stated, “Our strong financial position and positive outlook for future earnings growth supports this increase to our quarterly cash dividend. Contracted revenue backlog is now a record $11 billion. Our active fleet has grown with the commencement of two additional ultra-deepwater rigs this quarter alone. And our fleet will continue to expand as we deliver six new rigs through the end of next year, which we expect will earn favorable day rates and multi-year terms. We continue to have a very bullish outlook in terms of customer demand for both deep- and shallow-water offshore markets. These factors give us significant visibility into future cash flows.” Mr. Rabun added, “Management and the Board believe the new dividend payout is prudent and sustainable. We expect that we will continue to have adequate liquidity to meet capital commitments for our rigs under construction, as well as sufficient flexibility to make new investments and return capital to shareholders.” Ensco plc (NYSE: ESV) brings energy to the world as a global provider of offshore drilling services to the petroleum industry.
