PRESS RELEASE

NOBLE CORPORATION PLC REPORTS THIRD QUARTER 2015 RESULTS

OPERATIONAL EXCELLENCE AND FINANCIAL DISCIPLINE DRIVE STRONG PERFORMANCE

London, October 28, 2015 – Noble Corporation plc (NYSE:NE) today reported third quarter 2015 net income attributable to Noble Corporation of $326 million, or $1.32 per diluted share, on revenues of $897 million. Results for the quarter include the recognition of $148 million after tax, or $0.60 per diluted share, representing the proceeds of the Noble Homer Ferrington arbitration award. Excluding the impact of the arbitration award, net income attributable to Noble Corporation was $178 million, or $0.72 per diluted share, on revenues of $760 million. The results compared to net income attributable to Noble Corporation in the second quarter of 2015 of $159 million, or $0.64 per diluted share, on revenues of $794 million. For the third quarter of 2014, net income from continuing operations attributable to Noble Corporation was $147 million, or $0.57 per diluted share, on revenues of $829 million.

David W. Williams, Chairman, President and Chief Executive Officer of Noble Corporation plc, noted several highlights, stating, “Third quarter results reflect our commitment to excel on multiple fronts and further strengthen Noble’s excellent position in the offshore industry. Our well-contracted, premium fleet continued to experience strong operational excellence, with downtime in the quarter better than our guidance, resulting in a year-to-date operational downtime measure of an impressive 4 percent. The margin on our contract drilling operations, which was 67 percent in the quarter including the Noble Homer Ferrington arbitration award, remained steady at 59 percent on an adjusted basis, aided by another step down in operating costs, as we continue to gain efficiencies through cost control initiatives. These initiatives are expected to drive further reductions in operating costs and capital expenditures as we conclude 2015 and move into 2016. Finally, our commitment to financial discipline was evident in the quarter as we strengthened our balance sheet following the repayment of Senior Notes, utilizing cash on hand, while maintaining a robust measure of liquidity.”

With regard to the accounting treatment of the Noble Homer Ferrington arbitration award in third quarter results, the amount received totaled $177 million, with $137 million recognized as contract drilling services revenues, $30 million as interest income, and $10 million awarded for the reimbursement of costs and fees recognized as a reduction of contract drilling costs.

Contract drilling services revenues in the third quarter of 2015 were $874 million. Adjusted for the recognition of $137 million related to the Noble Homer Ferrington arbitration, contract drilling services revenues totaled $737 million, compared to revenues of $771 million in the second quarter of 2015. The 4 percent decline was largely attributable to lower average dayrates across the fleet and a modest increase in downtime, partially offset by an additional calendar day in the quarter. Fleet utilization in the third quarter was down slightly to 82 percent compared to 83 percent in the second quarter, driven by lower utilization in the floating rig fleet, while utilization of the jackup rig fleet was unchanged. Average daily revenues in the third quarter were $385,800. Adjusted for the arbitration award, average daily revenues declined to $325,500, compared to $340,200 in the second quarter, as both the floater and jackup rig sectors experienced lower average dayrates. Contract drilling services operating costs totaled $293 million in the third quarter, including the $10 million favorable impact from the arbitration, representing an 8 percent reduction from $319 million in the previous quarter. The decline was largely due to lower shorebase and operations support costs in addition to the arbitration impact, partially offset by modestly higher repair and maintenance expenses and costs associated with the reactivation in the quarter of the semisubmersible Noble Paul Romano and newbuild jackup Noble Tom Prosser. The continued decline in quarterly contract drilling operating costs was the primary factor behind the Company’s contract drilling services margin remaining steady, relative to the previous quarter, at 59 percent, exclusive of the benefit relating to settlement of the Noble Homer Ferrington arbitration.

Net cash from operating activities totaled $484 million in the third quarter of 2015, and $1.25 billion for the nine months ended September 30, 2015. Capital expenditures were $110 million in the third quarter, with expenditures for the nine months ended September 30, 2015 totaling $280 million. With the continued success of cost control initiatives, coupled with revised timing on certain expenditures, the Company has reduced its expected 2015 capital spending to $450 million from the original forecasted amount of $585 million.

At September 30, 2015, total debt was $4.5 billion compared to $4.8 billion at June 30, 2015. During the third quarter, the Company repaid Senior Notes totaling $350 million, utilizing cash on hand. With the reduction in total debt, the Company’s debt to total capitalization ratio was 37 percent at September 30, 2015, improving from 40 percent at June 30, 2015. Liquidity, defined as cash, cash equivalents and availability under revolving credit facilities, was $2.8 billion at the end of the third quarter, essentially unchanged from the level at June 30, 2015.

Operating Highlights

Utilization of the Company’s floating rig fleet, comprised of nine drillships and eight semisubmersibles, was 81 percent in the third quarter of 2015, compared to 82 percent in the previous quarter. The slight decline in utilization was caused primarily by idle time on the semisubmersible Noble Danny Adkins, which completed a contract in late August. The decline was partially offset by the reactivation of the semisubmersible Noble Paul Romano, which commenced a four-well contract in the U.S. Gulf of Mexico during the quarter. Average daily revenues for the floating fleet were $566,200 in the third quarter, including the Noble Homer Ferrington settlement. On an adjusted basis, these were $457,900, compared to $471,800 in the previous quarter. The reduction was due largely to lower average daily revenues on the Noble Danny Adkins. At the conclusion of the third quarter, the semisubmersible Noble Homer Ferrington remained cold stacked and the semisubmersibles Noble Max Smith and Noble Danny Adkins were idle. All nine of the Company’s drillships remained under contract. Following the conclusion of the third quarter, the Noble Danny Adkins was awarded a two-well contract for work in the U.S. Gulf of Mexico. The contract is expected to commence in early November 2015.

Utilization of the Company’s jackup rig fleet, comprised of 15 units, including one unit under construction, was 84 percent in the third quarter of 2015, unchanged from the previous quarter. Average daily revenues in the segment declined to $159,700 in the third quarter from $171,500 in the previous quarter, due primarily to the commencement of new contracts, or contract extensions at lower dayrates on the Noble Regina Allen, Noble Alan Hay and Noble David Tinsley. During the third quarter, the Company’s newbuild JU3000 jackup rig Noble Sam Hartley completed enhancements to its technical features. In September, the high-specification unit was awarded its initial contract by Total for work offshore Southeast Asia. The six well contract is expected to commence in early 2016 at a dayrate of $111,000 and take approximately three years to complete, adding an estimated $122 million to the Company’s backlog. Following the Noble Sam Hartley contract award, all six of Noble’s newbuild JU3000 jackups have secured contracts. Also, in early October, the newbuild jackup Noble Tom Prosser commenced an 18-month contract offshore Australia at a dayrate of $203,000. At the conclusion of the third quarter, the Noble Charles Copeland was idle, and the Noble Mick O’Brien remained idle, but the latter rig is expected to commence an estimated 400-day contract in the Middle East during the second quarter of 2016.

At September 30, 2015, Noble’s total contract backlog was $8.1 billion compared to $8.7 billion at June 30, 2015. For the remainder of 2015, 78 percent of the Company’s available rig operating days were committed to contracts, including 80 percent of floating rig days and 74 percent of jackup rig days. For 2016, an estimated 67 percent of available rig operating days are committed to contracts, consisting of 58 percent and 76 percent of floating and jackup rig days, respectively.

Outlook

In closing, Williams stated, “Noble possesses a number of important elements that remain critical for successfully managing the offshore industry’s cyclical trough. Of greatest importance is our contract cover, which remains strong into 2017 and has recently been supplemented by new contracts for the Noble Sam Hartley and Noble Danny Adkins. We believe the limited number of rigs in our fleet with near-term exposure to the current market are located in regions offering reasonable opportunities for follow-on assignments. Our total backlog of $8.1 billion at the conclusion of the third quarter should provide revenue potential in 2016 of an estimated $2.5 billion and another $1.6 billion in 2017. In addition, the consistency of our operational performance and our ability to effectively manage operating costs and capital expenditures have been instrumental in achieving better than expected levels of cash flow while maximizing liquidity. Finally, our recently announced dividend adjustment continues to provide a meaningful return to shareholders and is expected to increase liquidity by more than $220 million annually. This provides the Company with greater flexibility as we remain committed to positioning Noble to achieve value creation through the cycle.”
