PRESS RELEASE

NOBLE CORPORATION PLC REPORTS THIRD QUARTER 2014 RESULTS

London, England, October 29, 2014 – Noble Corporation plc (NYSE: NE) today reported third quarter 2014 net income from continuing operations of $147 million, or $0.57 per diluted share, compared to $140 million, or $0.54 per diluted share, for the second quarter of 2014. For the third quarter of 2013, net income from continuing operations totaled $165 million, or $0.64 per diluted share. Results for the third quarter of 2013 included a net pre-tax gain of $63 million, or $0.24 per diluted share, resulting from the sale of a jackup rig and a settlement related to the Company’s acquisition of Frontier Drilling in 2010, partially offset by an impairment charge taken on two submersibles that were subsequently sold during the first quarter of 2014. Revenues from continuing operations for the third quarter of 2014 were $829 million compared to $804 million in the second quarter of 2014 and $641 million in the third quarter of 2013. On August 1, 2014, Noble Corporation plc completed the spin-off of Paragon Offshore (NYSE: PGN). The results of Paragon Offshore and incremental spin-off related costs are classified as discontinued operations for the periods reported.

David W. Williams, Chairman, President and Chief Executive Officer of Noble Corporation plc noted, “During the third quarter, we commenced operations on two newbuild additions to the Noble fleet – the ultra-deepwater drillship Noble Sam Croft in the U.S. Gulf of Mexico and the high-specification jackup Noble Sam Turner in the North Sea. Combined, the two rigs added more than $50 million to quarterly revenues during the limited time they were working, contributing to the 4 percent growth in contract drilling services revenues when compared to the second quarter. The revenue improvement was partially offset by an increase in unplanned downtime and idle days in the fleet. However, our contract drilling operating margin held steady at 52 percent. Protecting our margins has our full focus and we have taken additional steps to control operating costs in the current industry environment.

“The third quarter also saw the delivery from Hyundai Heavy Industries of our final ultra-deepwater drillship ordered, the Noble Tom Madden. The rig is currently in transit to the U.S. Gulf of Mexico where it will commence a three-year contract in mid-December at a dayrate of $632,000, including mobilization revenues. Our 2014 planned newbuild deliveries, which total six units, will conclude with the expected delivery of the high-specification jackup Noble Sam Hartley this month, leaving one final newbuild project, the high-specification jackup Noble Lloyd Noble, with a planned delivery in mid-2016.”

MORE

Contract drilling services revenues for the third quarter of 2014 were $810 million, or 4 percent better than revenues of $779 million reported during the second quarter of the year. The increase in revenues was due in part to the commencement of operations on the drillship Noble Sam Croft and the jackup Noble Sam Turner, in addition to increased operating days on the semisubmersibles Noble Dave Beard and Noble Paul Romano. Partially offsetting these improvements was an increase in idle time on the semisubmersibles Noble Paul Wolff, Noble Max Smith and Noble Danny Adkins. Fleet utilization in the third quarter was essentially flat with the second quarter at 85 percent, as were average daily revenues, which increased slightly in the third quarter to $346,700 compared to the second quarter average of $346,500, primarily reflecting the addition of newbuild assets. Contract drilling services operating costs increased 4 percent during the third quarter to $386 million compared to $371 million in the second quarter of 2014. Higher costs associated with the addition of new rigs were partially offset by reduced mobilization costs.

Net cash from operating activities was $342 million in the third quarter of 2014, resulting in cash from operating activities through September 30, 2014 of $1.4 billion. Capital expenditures in the third quarter totaled $531 million, including $368 million related to the Company’s fleet expansion program. As of September 30, 2014, approximately $703 million in capital expenditures are still required to complete the Company’s final newbuild projects.

Debt as a percentage of total capitalization at September 30, 2014 was 37 percent, compared to 39 percent at June 30, 2014. Liquidity, defined as cash and cash equivalents plus availability under revolving credit facilities, was $2.0 billion at September 30, 2014 compared to $772 million at June 30, 2014. The decrease in debt as a percent of total capitalization and the increase in liquidity relate primarily to the $1.7 billion of net proceeds received from Paragon Offshore (NYSE: PGN) to settle intercompany debt prior to the Company’s spin-off of Paragon Offshore on August 1, 2014. Also, during the third quarter, the Company repurchased approximately 2 million of its ordinary shares under its previously approved authorization. The shares were repurchased at an average price per share of $26.22. At September 30, 2014, the number of shares outstanding and trading were 252.3 million and approximately 4.8 million shares remained available under the previously approved repurchase authorization.

Operating Highlights

The Company’s total contract backlog at September 30, 2014 was an estimated $10.6 billion compared to $11.1 billion at June 30, 2014. During the third quarter, the Company secured new contracts on two semisubmersibles, the Noble Danny Adkins and Noble Jim Thompson, adding an estimated $173 million to backlog. Utilization of the Company’s floating rig fleet (semisubmersibles and drillships) decreased to 80 percent in the third quarter of 2014 from 84 percent in the second quarter. The lower utilization was due, in part, to an increase in shipyard days on the semisubmersible Noble Amos Runner, higher idle days on the Noble Paul Wolff and Noble Max Smith and increased repair days on the drillship Noble Globetrotter I. The Noble Amos Runner, operating in the U.S. Gulf of Mexico, is expected to complete a maintenance project, including a five-year regulatory survey in early-November and return to its current contract. The rig is expected to remain under contract into November 2015. The Noble Paul Wolff and Noble Max Smith completed contracts offshore Brazil in April and August of 2014, respectively. Both rigs completed mobilization to Southeast Asia in October. The Noble Paul Wolff will commence a maintenance program, including a five-year regulatory inspection, while the Noble Max Smith will be available for contract opportunities in the Eastern Hemisphere. The drillship Noble Globetrotter I incurred 42 days of unpaid downtime to complete repairs. The rig returned to full operating dayrate on October 1, 2014. Average daily revenues in the floating rig fleet were $459,500 in the third quarter of 2014, an improvement of approximately 2 percent compared to $452,600 in the second quarter, primarily due to the commencement of operations on the Noble Sam Croft in the U.S. Gulf of Mexico.

Third quarter 2014 utilization of the Company’s jackup rig fleet was 91 percent compared to 87 percent utilization achieved during the second quarter. The improvement was largely due to an increase in operating days on the Noble Charles Copeland and the Noble Scott Marks, both operating in the Middle East. Average daily revenues during the third quarter improved to $182,100 from $178,300 during the second quarter, mainly due to the commencement of operations on the Noble Sam Turner.

At the end of the third quarter of 2014, 79 percent of the Company’s available rig operating days were committed for the remainder of 2014, including 74 percent of floating rig days and 86 percent of jackup rig days. For 2015, an estimated 72 percent of available rig operating days are committed, consisting of 69 percent and 77 percent of floating rigs and jackup rig days, respectively

Outlook

Williams closed by stating, “Four years ago we set out to transform the Noble fleet and we have achieved our goal. The spin-off of the standard capability fleet is complete and our newbuild construction program, which at one point totaled 14 projects, is near an end. Today, our fleet is among the youngest, most modern and technically advanced in the offshore drilling industry, with a significant backlog providing attractive contract coverage through 2015 and a customer base that reflects increased diversification. Our geographic presence is expanding as we reposition rigs, such as the deepwater semisubmersibles Noble Paul Wolff and Noble Max Smith, into regions with opportunities that we believe better match the technical features of these assets. At the same time, we possess a premier fleet in the prolific U.S. Gulf of Mexico, with eight ultra-deepwater, dynamically positioned drillships and semisubmersibles in the region.

“We believe the long-term fundamentals support the recovery of the offshore industry, leading to greater exploration and field development activities in the future, especially for the industry’s premium rigs. Our decision to seek shareholder approval for the repurchase of up to 37,000,000, or approximately 15 percent, of Noble’s outstanding ordinary shares, is a signal of our belief in the positive long-term outlook for offshore drilling and the improved competitive position that Noble now enjoys in our industry. Separately, we will pursue the development of an MLP, subject to market conditions and final board approval, because of the flexibility this provides as we consider cash allocation strategies which should create value for our shareholders and place Noble in a stronger competitive position.”
