Note 1 — Organization and Basis of Presentation

Noble Corporation plc, a public limited company incorporated under the laws of England and Wales (“Noble”, the “Company”, or “we”), is a leading offshore drilling contractor for the oil and gas industry. We provide contract drilling services to the international oil and gas industry with our global fleet of mobile offshore drilling units. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921. As of the filing date of this report, our fleet of 3836 drilling rigs consisted of 25 floaters and 1311 jackups.

We report our contract drilling operations as a single reportable segment, Contract Drilling Services, which reflects how we manage our business. The mobile offshore drilling units comprising our offshore rig fleet operate in a global market for contract drilling services and are often redeployed to different regions due to changing demands of our customers, which consist primarily of large, integrated, independent, and government-owned or controlled oil and gas companies throughout the world.

The accompanying unaudited condensed consolidated financial statements of Noble have been prepared pursuant to the rules and regulations of the US Securities and Exchange Commission (“SEC”) as they pertain to Quarterly Reports on Form 10-Q. Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. The unaudited financial statements are prepared on a going concern basis and reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the financial position and results of operations for the interim periods on a basis consistent with the annual audited consolidated financial statements. All such adjustments are of a recurring nature. The December 31, 2024, Condensed Consolidated Balance Sheet presented herein is derived from the December 31, 2024, audited consolidated financial statements. These interim financial statements should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2024, filed by Noble. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year.

Note 2 — Acquisitions

Business Combination with Diamond Offshore Drilling

On June 9, 2024, Noble entered into an agreement and plan of merger (the “Diamond Merger Agreement”) with Diamond Offshore Drilling, Inc. (“Diamond”), Dolphin Merger Sub 1, Inc., and Dolphin Merger Sub 2, Inc., under which Noble would acquire Diamond in a stock plus cash transaction (the “Diamond Transaction”). On September 4, 2024 (“the Diamond Closing Date”), Noble completed its acquisition of Diamond. Pursuant to the terms and conditions set forth in the Diamond Merger Agreement, Diamond shareholders received 0.2316 shares of Noble, plus cash consideration of $5.65 per share for each share of Diamond. Total consideration for the acquisition was $1.5 billion, which included $610.3 million in cash paid and $879.9 million in non-cash consideration, primarily related to A ordinary shares, par value $0.00001 per share (“Ordinary Shares”) issued to legacy Diamond shareholders and the replacement of each legacy Diamond performance-vesting and time-vesting restricted stock unit covering shares of Diamond. The Diamond Transaction was accounted for using the acquisition method of accounting under ASC Topic 805, Business Combinations, with Noble being treated as the accounting acquirer.

Pro Forma Financial Information

The following unaudited pro forma summary presents the results of operations as if the Diamond Transaction had occurred on January 1, 2023. The pro forma summary uses estimates and assumptions based on information available at the time. Management believes the estimates and assumptions to be reasonable; however, actual results may have differed significantly from this pro forma financial information. The pro forma information does not reflect any synergy savings that might have been achieved from combining the operations and is not intended to reflect the actual results that would have occurred had the companies actually been combined during the periods presented.

Note 3 — Accounting Pronouncements

Accounting Standards Adopted

There have been no new accounting standards adopted during the current quarter.

Recently Issued Accounting Standards

In ~~May~~July 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2025-0305, ~~Business~~Financial ~~Combinations~~Instruments—Credit ~~(Topic~~Losses ~~805) and Consolidation~~ (Topic ~~810~~326): ~~Determining~~Measurement ~~the~~of ~~Accounting~~Credit ~~Acquirer~~Losses infor ~~the~~Accounts ~~Acquisition~~Receivable ofand aContract ~~Variable interest~~Assets.

The Company does not expect this pronouncement to have any impact on our consolidated financial statements.

9In May 2025, the FASB issued ASU No. 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable interest. This update aims to improve the requirements for identifying the accounting acquirer in Topic 805, Business Combinations. The Company does not expect this pronouncement to have any impact on our consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments in the update require disclosure, in the notes to financial statements, of specified information about certain costs and expenses. An entity is not precluded from providing additional voluntary disclosures that may provide investors with additional decision-useful information. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company continues to evaluate the potential impact of this pronouncement.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires, among other things, the following for public business entities: (i) enhanced disclosures of specific categories of reconciling items included in the rate reconciliation, as well as additional information for any of these items meeting certain qualitative and quantitative thresholds, (ii) disclosure of the nature, effect, and underlying causes of each individual reconciling item disclosed in the rate reconciliation and the judgment used in categorizing them if not otherwise evident, and (iii) enhanced disclosures for income taxes paid, which includes federal, state, and foreign taxes, as well as for individual jurisdictions over a certain quantitative threshold. The amendments in ASU No. 2023-09 eliminate the requirement to disclose the nature and estimate of the range of the reasonably possible change in unrecognized tax benefits for the 12 months after the balance sheet date. The provisions of ASU No. 2023-09 are effective for annual periods beginning after December 15, 2024; early adoption is permitted. The Company expects this pronouncement will require changes to our tax reporting processes due to the expanded income tax disclosure requirements, but we do not anticipate the pronouncement will change total reported tax expense, tax assets, or tax liabilities.

In periods where the warrants are determined to be dilutive, the number of shares which will be included in the computation of diluted shares is determined using the Treasury Stock Method, adjusted for mandatory exercise provisions under the warrant agreements, if applicable.

10Share Capital

As of September 30, 2025, Noble had approximately 158.8 million Ordinary Shares outstanding as compared to approximately 158.9 million Ordinary Shares outstanding at December 31, 2024. In addition, as of September 30, 2025, 0.9 million Tranche 1 Warrants, 0.9 million Tranche 2 Warrants, and 2.8 million Tranche 3 Warrants were outstanding and exercisable. We also have 5.3 million Ordinary Shares authorized and reserved for issuance pursuant to equity awards under the Noble Corporation plc 2022 Long-Term Incentive Plan.

Our most recent quarterly dividend payment to shareholders, totaling approximately 79.4 million (or $0.50 per share), was declared on August 5, 2025, and paid on September 25, 2025, to shareholders of record at close of business on September 4, 2025.

The declaration and payment of dividends require authorization of the Board of Directors, provided that such dividends on issued share capital may be paid only out of the Company’s “distributable reserves” as determined by reference to relevant statutory accounts in accordance with English law. The Company is not permitted to pay dividends out of share capital, which includes share premiums. The payment of future dividends will depend on our results of operations, financial condition, cash requirements, future business prospects, the availability of sufficient distributable reserves, contractual and indenture restrictions, and other factors deemed relevant by our Board of Directors.

Share Repurchases

Under English law, the Company is only permitted to purchase its own Ordinary Shares by way of an “off-market purchase” pursuant to a contract approved by shareholders (except where the purchase is for the purposes of, or pursuant to, any employees’ share scheme). Such purchases may be paid for either (i) out of Noble’s “distributable reserves” as determined by reference to relevant statutory accounts in accordance with English law or (ii) from the proceeds of a fresh issue of shares made for the purpose of financing the purchase. On October 22, 2024, Noble’s Board of Directors authorized an increased share repurchase authorization of up to an additional $400 million and, at the 2025 annual general meeting of shareholders, shareholders approved the repurchase of up to 23,800,068 Ordinary Shares. The authorization by the Board of Directors has approximately $370 million remaining, does not have a fixed expiration, and may be modified, suspended, or discontinued at any time. None of the 23,800,068 Ordinary Shares authorized for repurchase by shareholders has yet been utilized and the authorization by shareholders expires on May 8, 2030 (subject to certain exceptions). The program does not obligate us to acquire any particular amount of Ordinary Shares. During the three and ~~six~~nine months ended ~~June~~September 30, 2025, we repurchased zero and 0.7 million of our Ordinary Shares, respectively. During the three and ~~six~~nine months ended ~~June~~September 30, 2024, we ~~did~~repurchased ~~not~~6.9 ~~repurchase~~million ~~any~~ of our Ordinary Shares pursuant to such authority. All repurchased shares were subsequently cancelled.

(the “Diamond Warrants”) were exercisable through December 3, 2024, for $5.65 in cash and 0.2316 Ordinary Shares at an exercise price of $29.22 per Diamond Warrant.

During the ~~second~~third quarter of 2025, we sold the Noble Highlander and the Pacific ~~Scirocco~~Meltem for ~~total~~net proceeds of $1587.65 million, resulting in a gain of $45.86 million.

11In August 2025, we announced our intent to dispose of the rigs Noble Globetrotter II and Noble Reacher. As of September 30, 2025, the Noble Globetrotter II and Noble Reacher qualified as held for sale and were included in “Other assets” on our Consolidated Balance Sheet at their combined carrying value of $54.0 million after a recognized aggregate non-cash impairment charge of $60.7 million.

We measured the impairment of the rigs and related assets as the amount by which the carrying amount exceeded the estimated fair value less costs to sell. We estimated the fair value of the assets using significant other observable inputs, representative of Level 2 fair value measurements, including binding contracts or indicative market values for the sale of rigs and related assets for use outside of the drilling industry.

Contract Balances

Accounts receivable are recognized when the right to the consideration becomes unconditional based upon contractual billing schedules. Payment terms on invoiced amounts are typically 30 to 60 days. Customer contract assets and liabilities generally consist of contract costs and deferred revenue resulting from past transactions related to the provision of services under contracts with customers. Current contract asset and liability balances are included in “Prepaid expenses and other current assets” and “Other current liabilities,” respectively, and noncurrent contract assets and liabilities are included in “Other assets” and “Other liabilities,” respectively, on our Condensed Consolidated Balance Sheets.

Certain direct and incremental costs incurred for upfront preparation, initial rig mobilization, and modifications are costs of fulfilling a contract and are recoverable. These recoverable costs are deferred and amortized ratably to contract drilling expense as services are rendered over the initial term of the related drilling contract. Costs incurred for the demobilization of rigs at contract completion are recognized as incurred during the demobilization process.

Certain of our contracts also include capital rig enhancements used to satisfy our performance obligations. Payments for these modifications are initially recognized as a contract liability and ratably as contract drilling revenue over the initial term of the related drilling contract. The costs are capitalized in accordance with our existing property and equipment accounting policy and depreciated over the estimated useful life of the improvement.

Note 8 — Income Taxes

At ~~June~~September 30, 2025, the Company had deferred tax assets of $~~297~~272.52 million, net of valuation allowance. Additionally, the Company also had deferred tax liabilities of $5.5 million, inclusive of a valuation allowance of $1516.69 million.

During the three months ended ~~June~~September 30, 2025, the Company recognized additional discrete deferred tax benefits of $226.31 million related to releases and adjustments of valuation allowance for deferred tax benefits primarily in Luxembourg.

During the ~~six~~nine months ended ~~June~~September 30, 2025, the Company recognized additional discrete deferred tax benefits of $7885.91 million related to releases and adjustments of valuation allowance for deferred tax benefits primarily in Luxembourg.

At ~~June~~September 30, 2024, the Company had deferred tax assets of $~~248~~340.89 million, net of valuation allowance. Additionally, the Company also had deferred tax liabilities of $7.8.9 million, inclusive of a valuation allowance of $18.52 million.

During the three months ended ~~June~~September 30, 2024, the Company recognized additional discrete deferred tax benefits of $6336.12 million related to releases and adjustments of valuation allowance for deferred tax benefits in Guyana and Luxembourg.

During the ~~six~~nine months ended ~~June~~September 30, 2024, the Company recognized additional discrete deferred tax benefits of $81117.68 million related to releases and adjustments of valuation allowance for deferred tax benefits in Guyana, Nigeria, Switzerland, and Luxembourg.

In deriving the above net deferred tax benefits, the Company relied on sources of income attributable to the projected taxable income for the period covered by the Company’s relevant existing drilling contracts based on the assumption that the relevant rigs will be owned by the relevant rig owners during the relevant existing drilling contract periods. Given the mobile nature of the Company’s assets, we are not able to reasonably forecast the jurisdictions in which taxable income from future drilling contracts may arise. We also have limited objective positive evidence in historical periods. Accordingly, in determining the amount of additional deferred tax assets to recognize, we did not consider projected book income beyond the conclusion of existing drilling contracts. As new drilling contracts are executed or as current contracts are extended, we will reassess the amount of deferred tax assets that are realizable. Finally, once we have established sufficient objective positive evidence for historical periods, we may consider reliance on forecasted taxable income from future drilling contracts.

At ~~June~~September 30, 2025, the reserves for uncertain tax positions totaled $~~196~~197.54 million (net of related tax benefits of $1216.50 million). At December 31, 2024, the reserves for uncertain tax positions totaled $197.9 million (net of related tax benefits of $3.7 million).

It is reasonably possible that our existing liabilities related to our reserve for uncertain tax positions may fluctuate in the next 12 months primarily due to the completion of open audits, the expiration of statutes of limitation, or favorable resolutions to ongoing tax litigation.

During the three months ended June 30, 2025, our tax provision included tax benefits of $22.3 million related to releases of valuation allowance for deferred tax benefits primarily in Luxembourg. Such tax benefits are offset by tax expenses of 16

During the three months ended September 30, 2025, our tax provision included tax benefits of $106.31 million related to ~~uncertain~~adjustments to valuation allowance for deferred tax ~~position~~benefits ~~movements~~primarily in Luxembourg and Switzerland. Such tax benefits were offset by recurring quarterly accruals of $6937.19 million mostly in Guyana, Luxembourg, Switzerland, and the United States. In October 2025, the Company received a favorable ruling in Ghana regarding certain audit claims; the Company expects to recognize tax benefits of approximately $65.0 million in the fourth quarter of 2025 related to this matter.

During the three and nine months ended September 30, 2024, we made no contributions to our pension plans. Effective December 31, 2016, employees and alternate payees accrue no future benefits under the US plans and, as such, Noble recognized no service costs with the plans for the three and ~~six~~nine months ended ~~June~~September 30, 2025 and 2024.

Note 10 — Commitments and Contingencies

Tax Matters

Audit claims of approximately $~~357~~356.34 million at ~~June~~September 30, 2025, attributable to income and other business taxes remain outstanding and are under continued objection by Noble. Such audit claims are mostly attributable to Brazil. ~~This~~and ~~remains~~remain under continued monitoring and evaluation on a quarterly basis as facts change and as audits and/or litigation continue to progress. We intend to vigorously defend our reported positions and currently believe the ultimate resolution of the audit claims will not have a material adverse effect on our consolidated financial statements.

We operate in numerous countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We recognize uncertain tax positions that we believe ~~have a greater than 50% likelihood of being sustained upon challenge by a tax authority. We cannot predict or provide assurance as to the ultimate outcome of any existing or future assessments.~~

Letters of Credit and Surety Bonds

As of ~~June~~September 30, 2025, we had $18.20 million of letters of credit issued under the 2023 Revolving Credit Facility and an additional $~~140~~149.47 million in letters of credit and surety bonds issued under bilateral arrangements which guarantee our performance as it relates to our drilling contracts, contract bidding, tax appeals, customs duties, and other obligations in various jurisdictions. We expect to comply with the underlying performance requirements and we expect obligations under these letters of credit and surety bonds will not be called.

Other Contingencies

We are a defendant in certain other claims and litigation arising out of operations in the ordinary course of business, including personal injury claims, the resolution of which, in the opinion of management, will not be material to our financial position, results of operations, or cash flows. There is inherent risk in any litigation or dispute and no assurance can be given as to the outcome of these claims.

Executive Overview

Noble is a leading offshore drilling contractor for the oil and gas industry. As of the filing date of this Quarterly Report on Form 10-Q, Noble performs, through its subsidiaries, contract drilling services with a fleet of 3836 drilling rigs, consisting of 25 floaters and 1311 jackups, after closing on the sale of the Noble Reacher on October 6, 2025, focused largely on ultra-deepwater and high-specification jackup drilling opportunities in both established and emerging regions worldwide. We typically employ each drilling unit under an individual contract, and many contracts are awarded based upon a competitive bidding process.

We report our contract drilling operations as a single reportable segment, Contract Drilling Services, which reflects how we manage our business. The mobile offshore drilling units comprising our offshore rig fleet operate in a global market for contract drilling services and are often redeployed to different regions due to changing demands of our customers, which consist primarily of large, integrated, independent and government-owned or controlled oil and gas companies throughout the world.

Market Outlook

In recent years, oil prices have generally remained at levels that are supportive of offshore exploration and development activity and global rig demand recovered to eclipse pre-pandemic levels, albeit with some moderation since early 2024 and a further correction more recently with spot prices for Brent crude generally in the mid to high $60s per barrel compared to an average price of $80 per barrel during 2024. Current demand and utilization levels are supported by the combination of the outlook for longer-term commodity prices, heightened focus on energy security, the capital intensity of depletion replacement, and relative attractiveness of offshore plays with respect to both cost and carbon emissions. The increase in global rig demand since 2021 has had a positive impact on dayrates for most rig classes although dayrates have generally plateaued more recently.

The global rig supply has come down from historic highs as Noble and other offshore drilling contractors have retired less capable and idle assets. Concurrently, the incoming supply of newbuild offshore drilling rigs has diminished materially, with several newbuild rigs stranded in shipyards. However, we expect many of these stranded newbuild rigs may continue to make their way into the global market over the next few years.

Although the market outlook in our business varies by geographical region and water depth and despite recent downward pressure on the price of oil, we remain encouraged by the long-term outlook in the ultra-deepwater floater market. However, within this ultra-deepwater market, our customers continue to focus on our highest specification floaters, which represents the majority of our floater fleet. Assuming current market fundamentals, continued customer prioritization towards these highest specification floaters is likely to result in lower utilization for our lower specification drillships and our semi-submersibles. Demand for midwater semisubmersibles is primarily driven by brownfield activity in mature basins, especially in Northwest Europe, South America, and the Asia Pacific regions, where a generally stable level of baseload demand is supported by infield drilling and plug and abandonment requirements. ~~Despite~~We ~~some recent contract suspensions in select jackup markets, we~~ have also observed an overall demand increase in the global jackup market since 2020. While we remain encouraged about overall long-term rig demand, as evidenced by recent multi-year, multi-rig contracts that we have booked into backlog, the near term utilization outlook for both floaters and jackups over the next several quarters is anticipated to be lower than the utilization rates realized during the prior two years. Furthermore, economic uncertainty ~~and lower commodity prices arising from recent trade policy and tariffs,~~ compounded with OPEC’s stated intent to increase oil production, collectively present a potential for additional demand risk for offshore rigs in the near term.

As of the date of this report, the majority of our jackup fleet is positioned in the North Sea. While we have seen generally stable demand in the UK and southern North Sea in recent years, overall activity levels in the region remain subdued compared to historical levels. Similarly, the ultra-harsh environment jackup market in Norway also remains below historical levels despite the market being attractive to operators given it is characterized by low-cost and low-emission barrels.

Recent contract awards and open tenders show an increasing proportion of multi-year contracts, although a significant number of shorter term commitments continue to be fixed, as well. Longer term contracts can generally provide economic efficiencies by reducing the number of rig contract start-ups, both with different customers and among different regions, which is expected to reduce incremental resources and costs. On the other hand, certain multi-year contracts that are scheduled to commence a year or longer into the future can present near term utilization inefficiency due to challenges with filling interim availability on the assets.

2223

The energy transition from hydrocarbons to renewables poses a challenge to the oil and gas sector and our market. Energy rebalancing trends have accelerated in recent years as evidenced by promulgated or proposed government policies and commitments by many of our customers to further invest in sustainable energy sources. Our industry could be further challenged as resource holders and policy makers continue to evaluate and calibrate strategies and capital flows to address global energy needs. Ultimately, however, there continues to be a global dependence on products made from hydrocarbons and on the combustion of hydrocarbons to provide reliable and affordable energy. Low-cost and low-emission barrels are expected to be the most attractive conventional source to meet energy needs both currently and in the future. Global energy demand is predicted to increase over the coming decades, and we expect that offshore oil and gas will continue to play an important and lasting role in meeting this demand.

Our cost profile remains sensitive to global labor market conditions, capital intensive repair and maintenance scopes on our rigs, global trade and sanctions regimes, including the impacts of new or increased tariffs or trade wars, and geopolitical crises and their respective regional and global ramifications. Each of these factors has the potential to adversely impact our ability to conduct our day-to-day operations and manage costs, with uncertainty related to trade policy and tariffs also having the ability to negatively impact rig demand.

Contract Drilling Services Backlog

We maintain a backlog of commitments for contract drilling services. Our contract drilling services backlog reflects estimated future revenues attributable to signed drilling contracts. As of ~~June~~September 30, 2025, contract drilling services backlog totaled approximately $7.41 billion.

We calculate backlog for any given unit and period by multiplying the full contractual operating dayrate for such unit by the number of days remaining in the period, and include certain assumptions based on the terms of certain contractual arrangements, discussed in the notes to the table below. The reported contract drilling services backlog does not include amounts representing revenues for mobilization, demobilization, and contract preparation, which are not expected to be significant to our contract drilling services revenues, amounts constituting reimbursables from customers, or amounts attributable to uncommitted option periods under drilling contracts or letters of intent.

The table below presents the amount of our contract drilling services backlog as of ~~June~~September 30, 2025, and the percent of available operating days committed for the periods indicated:

(1)Represents a ~~six~~three-month period beginning ~~July~~October 1, 2025.

(2)Noble entered into a multi-year Commercial Enabling Agreement (the “CEA”) with ExxonMobil in February 2020. Under the CEA, dayrates for the rigs are repriced on March 1 and September 1 each year to the projected market rate at the time the new rate goes into effect, subject to a scale-based discount and a performance bonus that appropriately aligns the interests of Noble and ExxonMobil. Under the CEA, the table above includes awarded and remaining current contract term to August 18, 2028, related to each of the four following rigs: the Noble Tom Madden, Noble Bob Douglas, Noble Don Taylor, and Noble Sam Croft. Under the CEA, ExxonMobil may reassign remaining contract term among rigs, subject to maintaining certain minimum contract term on the rig from which term is removed.

(3)Assuming approximately 40% of available performance revenue realized on a combined basis under certain long-term contracts with Shell (US) and ~~Total~~TotalEnergies ~~Energies~~(Suriname).

(4)In 2022, Noble renewed its five-year Framework Agreement with Aker BP (the “Framework Agreement”) for the provision of ultra-harsh environment jackup rigs, the Noble Integrator and Noble Invincible, for activities offshore Norway. Under the Framework Agreement, different rate structures apply reflecting different operating modes, agreed incentive schemes, and adjustments for operating expenses. Rate structures are adjusted annually to reflect market conditions.

(5)Percent of available days committed is calculated by dividing the total number of days our rigs are operating under contract for such period by the product of the number of our rigs, including cold-stacked rigs, and the number of calendar days in such period.

The amount of actual revenues earned and the actual periods during which revenues are earned may be materially different than the backlog amounts and backlog periods presented in the table above due to various factors, including, but not limited to, shipyard and maintenance projects, unplanned downtime, the operation of market benchmarks for dayrate resets, achievement of bonuses, weather conditions, reduced standby or mobilization rates, and other factors that result in applicable dayrates lower than the full contractual operating dayrate. In addition, amounts included in the backlog may change because drilling contracts may be varied or modified according to their terms or by mutual consent, or customers may exercise early termination rights contained in some of our drilling contracts or decline to enter into a drilling contract after executing a letter of intent. As a result, our backlog as of any particular date may not be indicative of our actual operating results for the periods for which the backlog is calculated. See Part I, Item 1A, “Risk Factors – Risks Related to Our Business and Operations – Our current backlog of contract drilling revenue may not be ultimately realized” in our Form 10-K.

As of ~~June~~September 30, 2025, ExxonMobil, Shell, BP, and TotalEnergies represented approximately 2623.53%, 1819.62%, 16.2%, and 12.25% of our backlog, respectively.

(1)We define utilization for a specific period as the total number of days our rigs are operating under contract divided by the product of the total number of our rigs, including cold stacked rigs, and the number of calendar days in such period. Information reflects our policy of reporting on the basis of the number of available rigs in our fleet.

(2)An operating day is defined as a calendar day during which a rig operated under a drilling contract. We define average dayrates as revenue from contract drilling services earned per operating day. Average dayrates exclude the effect of non-cash amortization related to favorable and unfavorable off-market customer contract assets and liabilities.

Contract Drilling Services Revenues

Floaters. During the ~~second~~third quarter of 2025, floaters generated revenue of $~~684~~630.32 million, as compared to $~~517~~605.73 million in the ~~second~~third quarter of 2024. The increase in revenue was mainly attributable to $~~297~~156.0 million provided by the additional floaters acquired in connection with the Diamond Transaction. These increases were partly offset by $97127.71 million from rigs with net changes in operating days in the current period ~~as well as $11~~.9 ~~million from a decrease in average dayrates in the current period.~~ Additionally, floater revenue from net non-cash amortization related to off-market customer contract assets and liabilities decreased $203.85 million in the current period.

Jackups. During the ~~second~~third quarter of 2025, jackups generated revenue of $127.83 million, as compared to $~~143~~158.02 million in the ~~second~~third quarter of 2024. The decrease in revenue was mainly attributable to $2651.78 million from rigs with net changes in operating days. This decrease was partly offset by $1822.18 million from an increase in average dayrates in the current period. ~~Additionally, jackup revenue from net non-cash amortization related to off-market customer contract assets and liabilities decreased $1.0 million in the current period.~~

Operating Costs and Expenses

Floaters. During the ~~second~~third quarter of 2025, total contract drilling services costs related to floaters was $~~396~~381.86 million, as compared to $~~248~~332.76 million in the ~~second~~third quarter 2024. The primary drivers of this increase were $~~112~~71.51 million related to the additional floaters acquired in connection with the Diamond Transaction, $277.03 million in ~~mobilization~~fuel, ~~and~~ $415.0 million in ~~non-labor and operations support costs, incremental~~ insurance costs, and ~~other~~$3.6 ~~costs~~million ~~across~~in ~~the fleet~~mobilization.

Contract Drilling Services Revenues

Floaters. During the ~~six~~nine months ended ~~June~~September 30, 2025, floaters generated revenue of $12.40 billion, as compared to $1.06 billion in the ~~six~~nine months ended ~~June~~September 30, 2024. The increase in revenue was mainly attributable to $~~512~~668.43 million provided by the additional floaters acquired in connection with the Diamond Transaction. These increases were partly offset by $96226.01 million from rigs with net changes in operating days in the current period as well as $2017.49 million from a decrease in average dayrates in the current period. Additionally, floater revenue from net non-cash amortization related to off-market customer contract assets and liabilities decreased $3034.40 million in the current period.

Jackups. During the ~~six~~nine months ended ~~June~~September 30, 2025, jackups generated revenue of $~~266~~394.70 million, as compared to $~~260~~419.91 million in the ~~six~~nine months ended ~~June~~September 30, 2024. The ~~increase~~decrease in revenue was mainly attributable to a decrease of $3463.68 million from anrigs ~~increase~~with net changes in ~~average~~operating ~~dayrates~~days induring the current period. This ~~increase~~decrease was partly offset by $1355.86 million from ~~rigs~~an ~~with~~increase in average dayrates in the current period.

Operating Costs and Expenses

Floaters. During the ~~six~~nine months ended ~~June~~September 30, 2025, total contract drilling services costs related to floaters was $~~788~~1.62 ~~million~~billion, as compared to $~~538~~870.39 million in the ~~six~~nine months ended ~~June~~September 30, 2024. The primary drivers of this increase were $~~236~~307.01 million related to the additional floaters acquired in connection with the Diamond Transaction, $3538.06 million in mobilization, and $3930.21 million in non-labor and operations support costs, incremental insurance costs, and other costs across the fleet. These increases were partially offset by decreases of $1613.34 million in labor, $2238.05 million in repairs and maintenance, ~~$6.0 million in transportation,~~ as well as insurance proceeds received for a certain rig totaling $15.6 million. Further, there was a decrease of $14.2 million related to certain rigs sold or no longer operated by Noble.

Jackups. During the ~~six~~nine months ended ~~June~~September 30, 2025, total contract drilling services cost related to jackups was $~~175~~279.94 million, as compared to $~~187~~289.40 million in the ~~six~~nine months ended ~~June~~September 30, 2024. The primary drivers of this decrease were $37.52 million related to repairs and maintenance, ~~$3.3 million in non-labor and operations support costs across the fleet,~~ as well as insurance proceeds received for a certain rig totaling $20.0 million. Further, there was a decrease of $1110.17 million ~~after~~related ~~the~~to ~~completion~~certain ofrigs ~~disposal~~sold ~~activities~~or ~~regarding~~no ~~certain~~longer ~~rigs~~operated by Noble. These decreases were partially offset by increases of $2628.4 million in labor, ~~transportation~~mobilization, fuel, and other costs across the fleet.

Depreciation and amortization. Depreciation and amortization totaled $~~290~~437.25 million and $~~177~~287.53 million during the ~~six~~nine months ended ~~June~~September 30, 2025 and 2024, respectively. Depreciation and amortization increased by $~~112~~150.81 million in the current period primarily due to the Diamond Transaction.

General and administrative. General and administrative expenses totaled $70103.25 million and $65109.62 million during the ~~six~~nine months ended ~~June~~September 30, 2025 and 2024, respectively. The ~~increase~~decrease was primarily due to individually insignificant items within certain corporate charges such as professional fees, corporate leases, and employee -related costs.

~~Merger and integration costs. Noble incurred $20.2 million and $19.9 million of merger and integration costs during the six months ended June~~ 30, 2025 and 2024, respectively. In the current period, costs incurred related primarily to the Diamond Transaction. In the prior period, costs incurred related to the Business Combination with Maersk Drilling. In both periods, such direct costs related primarily to professional fees and certain integration-related activities.

During the nine months ended September 30, 2024, we sold the Noble Explorer, resulting in a pre-tax gain of $17.4 million.

Loss on impairment. During the nine months ended September 30, 2025, we recorded a loss on impairment of $60.7 million to reduce the carrying values of the Noble Globetrotter II and Noble Reacher to their estimated fair value less costs to sell. There were no impairments recorded during the nine months ended September 30, 2024. For additional information, see “Note 5 — Property and Equipment” to our unaudited condensed consolidated financial statements.

Other Income and Expenses

Interest expense, net of amounts capitalized. Interest expense totaled $80121.50 million and $2954.5 million during the ~~six~~nine months ended ~~June~~September 30, 2025 and 2024, respectively. Interest expense increased as a result of the Diamond Transaction and primarily relates to our 2030 Notes as well as the Diamond Second Lien Notes. For additional information, see “Note 6 — Debt” to our unaudited condensed consolidated financial statements.

Interest income and other, net. Noble recognized interest and other income of $67.53 million and interest income and other losses of $1210.96 million during the ~~six~~nine months ended ~~June~~September 30, 2025 and 2024, respectively.

Such tax benefits ~~are~~were offset by ~~tax expenses related to a net increase in uncertain tax positions of $6.9 million and~~ recurring quarterly accruals of $59134.30 million mostly in Guyana, Luxembourg, Switzerland, and Nigeria.

Liquidity and Capital Resources

Sources and Uses of Cash

Our principal sources of capital in the current period were cash generated from operating activities. Cash on hand during the current period was primarily used for the following:

•normal recurring operating expenses;

•capital expenditures;

•fees and expenses related to merger and integration costs;

•share repurchases and dividend payments; and

•certain contractual cash obligations and commitments.

Our anticipated cash flow needs, both in the short term and long term, may also include repurchases, redemptions, or repayments of debt and interest.

We currently expect to fund our cash flow needs with cash generated by our operations, cash on hand, proceeds from sales of assets, or borrowings under the 2023 Revolving Credit Facility, and we believe this will provide us with sufficient liquidity to fund our cash flow needs over the next 12 months. Subject to market conditions and other factors, we may also issue equity or long-term debt securities to fund our cash flow needs and for other purposes. We have been incurring expenses and capital costs related to an incident regarding one floater. These incurred costs exceeded the applicable deductible. We have received partial insurance recoveries for these claims and we continue to seek insurance recoveries for the remainder of the incurred and anticipated costs.

Net cash provided by operating activities was $487.4 million and $235.5 million for the six months ended June 30, 2025 and 2024, respectively. The increase in net cash provided by operating activities for the six months ended June 30, 2025, was primarily attributable to improvements in cash flows from operating assets and liabilities, with key drivers being an increase in payments from customers partially offset by an increase in payments to vendors, as well as the Diamond Transaction. We had working capital of $573.1 million at June 30, 2025, and $448.5 million at December 31~~, 2024.~~

Net cash ~~used~~provided inby ~~investing~~operating activities was $~~191~~764.76 million and $~~299~~519.83 million for the ~~six~~nine months ended ~~June~~September 30, 2025 and 2024, respectively,. ~~and~~The ~~primarily~~increase ~~consisted~~in ofnet ~~capital~~cash ~~expenditures~~provided onby ~~routine~~operating ~~projects~~activities ~~associated~~for ~~with~~the ~~overhauls~~nine ~~and~~months ~~upgrades~~ended onSeptember ~~various rigs.

At September 30, 2025, we had a total contract drilling services backlog of approximately $7.1 billion, which includes a commitment of 61% of available days for the remainder of 2025. For additional information regarding our backlog, see “Contract Drilling Services Backlog.”

Capital Additions

Capital additions totaled $~~204~~339.30 million for the ~~six~~nine months ended ~~June~~September 30, 2025, and consisted of the following:

•$~~135~~202.26 million for sustaining capital;

•$58116.62 million in major projects, including subsea and other related projects, and capital spares; and

•$1020.52 million for rebillable capital and contract modifications.

Our total capital additions estimate for the year ending December 31, 2025, net of reimbursements, is expected to range between $~~400~~425.0 million and $450.0 million. We expect to fund these capital additions with cash generated by our operations and cash on hand.

30From time to time we consider possible projects and may have certain events that would require expenditures that are not included in our capital budget, and such unbudgeted expenditures could be significant. This includes additional capital expenditures to upgrade rigs for specific customer requirements or contracts. The total amount of capital that we ultimately spend is partly dependent on broader market conditions, the actual level of current and expected contracting activity, as well as costs related to satisfying regulatory requirements. Given many of our capital related projects can take considerable time to complete, the actual costs and timing of expenditures may vary materially from estimates based on various factors, many of which are out of our control. In addition, while liquidity and preservation of capital remains our top priority, we will continue to evaluate acquisitions of drilling units from time to time.

Critical Accounting Estimates

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States, which require us to make estimates that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ from our estimates and assumptions and any such differences could be material to our consolidated financial statements. The following accounting policies involve critical accounting estimates because they are particularly dependent on estimates and assumptions made by Noble about matters that are inherently uncertain. We disclose our significant accounting policies in “Note 1— Organization and Significant Accounting Policies” to our audited consolidated financial statements included in Part II, Item 8 of our Form 10-K.

For information about our critical accounting policies and estimates, see Part II, Item 7, “Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates” in our Form 10-K. As of ~~June~~September 30, 2025, there have been no material changes to the judgments, assumptions, and estimates upon which our critical accounting policies and estimates are based.

See Part I, Item 1, Financial Statements, “Note 3 — Accounting Pronouncements,” to the unaudited condensed consolidated financial statements for a description of the recent accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There has been no significant change in our exposure to market risk when compared to those disclosed in Part II, Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” in our Form 10-K.

Item 4. Controls and Procedures

Conclusions Regarding Disclosure Controls and Procedures

Robert W. Eifler, President and Chief Executive Officer (Principal Executive Officer) of Noble, and Richard B. Barker, Executive Vice President and Chief Financial Officer (Principal Financial Officer) of Noble, have evaluated the disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”)) of Noble as of the end of the period covered by this report. On the basis of this evaluation, our Principal Executive Officer and Principal Financial Officer have concluded that Noble’s disclosure controls and procedures were effective as of ~~June~~September 30, 2025. Noble’s disclosure controls and procedures are designed to ensure that information required to be disclosed by Noble in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including its principal executive and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

In accordance with interpretive guidance issued by SEC staff, companies may exclude an acquired business from the assessment of internal control over financial reporting during the first year following the date on which the acquisition is completed and from the assessment of disclosure controls and procedures to the extent subsumed in such internal control over financial reporting. In accordance with this guidance, as the Company acquired Diamond on September 4, 2024, Management’s, including our Principal Executive Officer and Principal Financial Officer, evaluation and conclusion as to the effectiveness of the Company’s disclosure controls and procedures as of June 30, 2025, excluded the portion of disclosure controls and procedures that are subsumed by internal control over financial reporting of Diamond.

Changes in Internal Control Over Financial Reporting

There were no changes in Noble’s internal control over financial reporting that occurred during the quarter ended ~~June~~September 30, 2025, that have materially affected, or are reasonably likely to materially affect, the internal control over financial reporting of Noble.

Limitations on the Effectiveness of Controls

Internal control over financial reporting includes the controls themselves, monitoring (including internal auditing practices), and actions taken to correct deficiencies as identified. There are inherent limitations to the effectiveness of internal control over financial reporting, however well designed, including the possibility of human error and the possible circumvention or overriding of controls. The design of an internal control system is also based in part upon assumptions and judgments made by management about the likelihood of future events, and there can be no assurance that an internal control will be effective under all potential future conditions. As a result, even an effective system of internal controls can provide no more than reasonable assurance with respect to the fair presentation of financial statements and the processes under which they were prepared.
