2018 HIGHLIGHTS AND RECENT ACCOMPLISHMENTS:

• Best safety year on record

• Record fleet performance with 97.3 percent uptime for the year

• Contract backlog ends year at $2.4 billion

• Exercised an option for the purchase of second newbuild jackup

• Reactivation completed on three floating rigs and a jackup

LONDON, February 20, 2019 – Noble Corporation plc (NYSE: NE, the Company) today reported a net loss attributable to the Company for the three months ended December 31, 2018 (fourth quarter) of $33 million, or $0.13 per diluted share, on revenues of $310 million. Results for the fourth quarter included a discrete tax benefit and a gain from the retirement of debt, which together totaled $66 million, or $0.27 per diluted share, net of tax. These favorable items were partially offset by a loss of $9 million, or $0.04 per diluted share, resulting from the impairment of assets. Excluding the net favorable items, the net loss attributable to Noble Corporation plc for the three months ended December 31, 2018, would have been $90 million, or $0.36 per diluted share.

For the twelve months ended December 31, 2018, Noble Corporation plc reported a net loss attributable to the Company of $885 million, or $3.59 per diluted share, on revenues of $1.1 billion. Results for the year included net unfavorable items totaling $432 million, or $1.75 per diluted share, net of tax and non-controlling interests, related to asset impairments and the retirement of debt, partially offset by discrete tax items. Excluding the net unfavorable items, the net loss attributable to Noble Corporation plc for the twelve months ended December 31, 2018, would have been $453 million, or $1.84 per diluted share.

Julie J. Robertson, Chairman, President and Chief Executive Officer of Noble Corporation plc, noted, “While 2018 was another challenging year, Noble set a second consecutive annual record for operational performance, registering 97.3 percent uptime across the fleet, while again establishing record metrics for safety. We achieved these important milestones while experiencing steady improvement in fleet activity, with utilization of both our floating and jackup fleets completing the fourth quarter of 2018 at their highest levels for the year. Also, we completed reactivation projects during the year on three floating units and a jackup, with a reactivation project on a fourth floating unit in progress as the year concluded. These rig reactivations position the Company to successfully compete to fill incremental customer needs in 2019.”

Contract drilling services revenues for the fourth quarter of 2018 totaled $292 million, a nine percent improvement when compared to revenues of $267 million in the preceding quarter of 2018. The growth in revenues was driven largely by higher fleet activity, led by the floating rig fleet where operating days improved 23 percent from the previous quarter. Also, revenues were supported by a reduction in fleet downtime, which declined to 2.1 percent in the fourth quarter (97.9 percent uptime) compared to fleet downtime of 5.2 percent in the preceding quarter of 2018. The improvement in fleet operating days drove total fleet utilization in the fourth quarter to 75 percent, the highest level experienced in 2018. The measure was up from 69 percent in the preceding quarter of 2018.

Contract drilling services costs for the fourth quarter of 2018 increased 10 percent to $179 million compared to $163 million in the preceding quarter of 2018. The increase was due largely to higher fleet activity, including increased operating days for the drillship Noble Tom Madden, the semisubmersible Noble Clyde Boudreaux and the jackup Noble Sam Hartley. Reactivation costs associated with the drillship Noble Sam Croft and other measures directed at elevating overall fleet readiness also contributed to the increase in costs. Contract drilling margin for the fourth quarter was 39 percent, unchanged from the preceding quarter in 2018.

Operating Highlights

Utilization in the fourth quarter of the Company’s floating rig fleet, consisting of eight drillships and four semisubmersibles, improved to 56 percent compared to 45 percent in the previous quarter of 2018, and 37 percent in the first quarter of 2018, which represented the lowest utilization

measure for the floating fleet during the year. A 23 percent increase in floating fleet operating days, when compared to the third quarter, was largely driven by the semisubmersible Noble Clyde Boudreaux, following a full quarter of operations offshore Myanmar, and the drillship Noble Tom Madden, which, in October 2018, commenced operations offshore Guyana. Both rigs completed reactivation programs during the third and fourth quarters of 2018, respectively. Revenues for the floating fleet in the fourth quarter advanced 17 percent when compared to the previous quarter in 2018 following increased contributions from the semisubmersible Noble Clyde Boudreaux, as well as the drillships Noble Tom Madden, Noble Globetrotter II and Noble Don Taylor. The reactivation of the drillship Noble Sam Croft continued in the fourth quarter ahead of an expected first quarter 2019 contract commencement in the U.S. Gulf of Mexico, to be followed by a contract assignment in South America, which should commence by mid-2019. The Company began 2019 with eight of its nine actively marketed floating units under contract, amounting to 49 percent of the available days for the year.

Utilization in the fourth quarter of the Company’s jackup fleet, comprised of 12 active units, was 94 percent compared to 93 percent in the preceding quarter of 2018, and 56 percent in the first quarter, which represented the lowest measure in 2018. The slight improvement from the preceding quarter was due primarily to higher activity on the Noble Sam Hartley, which in October commenced operations in the North Sea following relocation of the rig from Southeast Asia. The improvement in activity was partially offset by the Noble Tom Prosser, which completed a contract offshore East Timor in November. The rig was idle for the remainder of the fourth quarter and into the first quarter of 2019 pending the completion of a five-year regulatory survey. The Noble Tom Prosser is expected to recommence operations in the near term offshore Australia and remain under contract into the first half of 2020. When compared to the third quarter, jackup revenues in the fourth quarter of 2018 were essentially flat. Following the close of the fourth quarter, the standard-duty jackup Noble Gene House, which completed a contract in late-December 2018, was retired from service. With the retirement of the Noble Gene House, the Company’s jackup fleet stands at 12 units, including the recently acquired jackup Noble Johnny Whitstine. As previously reported, the Company exercised an option to purchase a second newbuild jackup, the Noble Joe Knight, concurrent with the award of a three-year contract. The Company began 2019 with all 12 of its jackup rigs contracted, covering 75 percent of the available days in the year.

Backlog, Capital and Balance Sheet

At December 31, 2018, the Company’s contract backlog was $2.4 billion, with an estimated $1.5 billion related to the floating rig fleet and $926 million to the jackup fleet. Approximately $945 million of the backlog is attributable to the year 2019, with an estimated 62 percent of the available days in the year committed to contracts across the Noble fleet.

3

Capital expenditures for the fourth quarter of 2018 were $61 million, of which $22 million was devoted to sustaining capital and $39 million related to fleet projects, reactivation programs and other projects. For the year 2018, capital expenditures totaled $221 million, which included $83 million in sustaining capital, $34 million related to the purchase of the Noble Johnny Whitstine and $104 million for fleet projects, reactivation programs and other projects. Capital expenditures associated with the purchase of the Noble Johnny Whitstine exclude $60 million of the rig’s purchase price, which was seller-financed. The Company expects capital expenditures for the full year of 2019 to total $250 million. This estimate includes $90 million in sustaining capital, $30 million related to the purchase of the Noble Joe Knight and $130 million for fleet projects, reactivation programs and other projects. The pending purchase of the Noble Joe Knight also includes $54 million with seller-financing similar to the Noble Johnny Whitstine, which is excluded from the full year 2019 capital estimate.

At December 31, 2018, cash and equivalents totaled $375 million compared to $326 million at the conclusion of the third quarter in 2018, while revolving credit facilities remained undrawn. Total debt at the conclusion of 2018 was $3.9 billion, essentially unchanged from the previous quarter.

Outlook

Ms. Robertson highlighted the strong geographic alignment of the Noble fleet and its positive implications for 2019. She stated, “As we commence the new year, 85 percent of our jackup fleet is, or will soon be operating in the North Sea and Middle East, two outstanding regions when we consider prospects for incremental jackup demand. Also, we expect to benefit from the presence of our floating rigs in the Western Hemisphere, where increased levels of exploration and growing customer activity are expected to drive additional rig needs, as demonstrated by the recent one-year contract award for the Noble Tom Madden offshore Guyana. Our regional alignment and continued operational excellence should lead to year-over-year improvement in total fleet operating days.”

NON-GAAP RECONCILIATION

Certain non-GAAP performance measures and corresponding reconciliations to GAAP financial measures for the Company have been provided for meaningful comparisons between current results and prior operating periods. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that excludes or includes amounts that are not normally included or excluded in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles. In order to fully assess the financial operating results, management believes that the results of operations, adjusted to exclude the following items, which are included in the Company’s press release issued on February 20, 2019, and discussed in the related conference call on February 21, 2019, are appropriate measures of the continuing and normal operations of the Company:

(i) In the first and fourth quarter of 2018, a loss on debt extinguishment;

(ii) In the second quarter of 2018, an impairment of three of our rigs and certain capital spares equipment;

(iii) In the third and fourth quarter of 2018, discrete tax benefits; and

(iv) In the fourth quarter of 2018, an impairment of two of our rigs.

These non-GAAP adjusted measures should be considered in addition to, and not as a substitute for, or superior to, contract drilling revenue, contract drilling cost, contract drilling margin, average daily revenue, operating income, cash flows from operations, or other measures of financial performance prepared in accordance with GAAP. Please see the following Non-GAAP Financial Measures and Reconciliations for a complete description of the adjustments.
