Noble Corp plc

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 29 drilling rigs consisted of 24 floaters and 5 jackups (excluding certain rigs currently operating under a bareboat charter agreement).

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, 2025, Condensed Consolidated Balance Sheet presented herein is derived from the December 31, 2025, 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, 2025, filed by Noble. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Amounts in the accompanying tables and footnotes are presented in thousands, unless otherwise noted.

The Company does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.

Note 3 — Earnings (Loss) Per Share

The following table presents the computation of basic and diluted earnings (loss) per share:

Only those items having a dilutive impact on our basic earnings (loss) per share are included in diluted earnings (loss) per share. The following table displays the share-based instruments that have been excluded from diluted earnings (loss) per share since the effect would have been anti-dilutive:

(1)Represents the total number of share-based awards and warrants outstanding which did not have a dilutive effect. In periods where the share-based awards and 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.

Share Capital

As of September 30, 2026, Noble had approximately $159.7 million Ordinary Shares outstanding as compared to approximately 158.9 million Ordinary Shares outstanding at December 31, 2025. In addition, as of September 30, 2026,0.7 million Tranche 1 Warrants (as defined below) and 0.7 million Tranche 2 Warrants (as defined below) were outstanding and exercisable. Furthermore, new equity awards may be granted under the Noble Corporation plc 2022 Long-Term Incentive Plan, pursuant to which, up to 3.9 million new Ordinary Shares may be issued.

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. During each of the quarters ended September 30, 2026 and 2025, we declared and paid a dividend of $0.50 per share.

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 the Company’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, the Company’s Board of Directors authorized an increased share repurchase authorization of up to an additional $400.0 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 $370.0 million remaining, does not have a fixed expiration, and may be modified, suspended, or discontinued at any time. None of the shareholder authorization to purchase up to 23,800,068 Ordinary Shares has yet been utilized and the authorization by shareholders expires on May 8, 2030 (subject to certain exceptions). The program does not obligate the Company to acquire any particular amount of Ordinary Shares. During the three and nine months ended September 30, 2026, the Company repurchased none of the Company’s Ordinary Shares. During the three and nine months ended September 30, 2025, the Company repurchased none and 0.7 million of the Company’s Ordinary Shares, respectively. All repurchased shares were subsequently cancelled, and the nominal value of the repurchased shares was transferred to the Capital Redemption reserve. Under this program, repurchases may be made from time to time using a variety of methods such as open market purchases and privately negotiated transactions, in compliance with relevant rules and regulations. In establishing this program, the Board considered the benefits to shareholders of providing the business with this additional capital allocation flexibility to promote long-term value for shareholders alongside other uses of capital.

Warrants

The tranche 1 warrants (the “Tranche 1 Warrants”) are exercisable forone Ordinary Share per warrant at an exercise price of $19.27 per warrant, the tranche 2 warrants (the “Tranche 2 Warrants”) are exercisable forone Ordinary Share per warrant at an exercise price of $23.13 per warrant, and the tranche 3 warrants, which expired on February 4, 2026, were exercisable forone Ordinary Share per warrant at an exercise price of $124.40 per warrant.

Note 4 — Property and Equipment

Property and equipment, at cost, for Noble consisted of the following:

Capital additions, including capitalized interest, during the three months ended September 30, 2026 and 2025, totaled $202.5 million and $134.7 million, respectively. Capital additions, including capitalized interest, during the nine months ended September 30, 2026 and 2025, totaled $573.4 million and $339.0 million, respectively.

In the second quarter of 2026, the Ocean Apexmet the criteria to be classified as held for sale and we recorded a loss on impairment of $42.3 million to reduce its carrying value to its estimated fair value less costs to sell. We estimated the fair value of the asset using significant other observable inputs representative of Level 2 fair value measurements, including binding contracts or indicative market values for the sale of rigs. During the third quarter of 2026, we completed the sale of the Ocean Apex for net proceeds of approximately $5.1 million.

As of September 30, 2026, the Noble Globetrotter II and Noble Resolve qualified as held for sale and were included in “Other assets” on our Condensed Consolidated Balance Sheet at the combined carrying value of $91.3 million. In October 2026, we completed the sale of the Noble Resolve for total proceeds of approximately $64 million, $19.2 million of which was received in the fourth quarter of 2025.

The amendment to the Revolving Credit Facility increased the commitments to $650.0 million and extended the maturity date to May 2031. Subsequently, on September 16, 2026, we made an additional amendment to the Revolving Credit Facility to clarify the types of bilateral credit instruments which may be secured thereunder. The guarantors under the Revolving Credit Facility are the same subsidiaries of Noble Finance II LLC, a wholly-owned, indirect subsidiary of Noble (“Noble Finance II”), that are or will be guarantors of the 2030 Notes and the 2034 Notes (each as defined below). As of September 30, 2026, we hadno borrowings outstanding and $6.7 million of letters of credit issued under the Revolving Credit Facility.

6.250% Senior Notes due 2034

On June 11, 2026, Noble Finance II issued $800.0 million in aggregate principal amount of its 6.250% Senior Notes due 2034 (the “2034 Notes”). The 2034 Notes were issued pursuant to an indenture, dated as of June 11, 2026, among Noble Finance II, the subsidiaries of Noble Finance II party thereto, as guarantors, and the trustee, paying agent, and registrar.

The 2034 Notes are unconditionally guaranteed on a senior unsecured basis by the above guarantors and will be unconditionally guaranteed on the same basis by certain of Noble Finance II’s future subsidiaries that guarantee certain indebtedness of Noble Finance II and the above guarantors, including the Revolving Credit Facility.

The 2034 Notes will mature on June 15, 2034, and interest on the 2034 Notes is payable semi-annually in arrears on each June 15 and December 15, commencing December 15, 2026, to holders of record on the June 1 and December 1 immediately preceding the related interest payment date, at a rate of 6.250% per annum.

8.000% Senior Notes due 2030

In 2023, Noble Finance II issued $600.0 million in aggregate principal amount of its 8.000% Senior Notes due 2030 (the “Initial 2030 Notes”). On August 22, 2024, Noble Finance II issued an additional $800.0 million in aggregate principal amount of its 8.000% Senior Notes due 2030 (the “Additional 2030 Notes” and, together with the Initial 2030 Notes, the “2030 Notes”) at a premium of 103% bringing the total outstanding principal amount to $1.4 billion. On June 11, 2026, Noble Finance II redeemed $300.0 million aggregate principal amount of the 2030 Notes for $312.0 million bringing the total outstanding principal amount to $1.1 billion. The 2030 Notes were issued pursuant to an indenture, dated as of April 18, 2023, among Noble Finance II, the subsidiaries of Noble Finance II party thereto, as guarantors, and the trustee, paying agent, and registrar.

The 2030 Notes are unconditionally guaranteed on a senior unsecured basis by the above guarantors and will be unconditionally guaranteed on the same basis by certain of Noble Finance II’s future subsidiaries that guarantee certain indebtedness of Noble Finance II and the above guarantors, including the Revolving Credit Facility.

The 2030 Notes will mature on April 15, 2030, and interest on the 2030 Notes is payable semi-annually in arrears on each April 15 and October 15, to holders of record on the April 1 and October 1 immediately preceding the related interest payment date, at a rate of 8.000% per annum.

8.500% Senior Secured Second Lien Notes due 2030

In 2023, Diamond Foreign Asset Company and Diamond Finance, LLC issued $550.0 million aggregate principal amount of 8.500% Senior Secured Second Lien Notes due October 2030 (the “Diamond Second Lien Notes”) with interest payable semi-annually in arrears on April 1 and October 1 of each year.

On June 11, 2026, Diamond Foreign Asset Company redeemed the remaining $495.0 million aggregate principal amount of the Diamond Second Lien Notes for $522.1 million.

Noble Finance II Financial Information

The indentures governing the 2030 Notes and the 2034 Notes contain covenants that require Noble Finance II to furnish to holders of the 2030 Notes and the 2034 Notes certain financial information relating to Noble Finance II and its restricted subsidiaries. The obligation to furnish such information may be satisfied by providing financial information of Noble along with a description of the differences between such information and the financial information of Noble Finance II and its restricted subsidiaries on a standalone basis. As a result of Noble conducting substantially all of its business through Noble Finance II, the financial position and results of operations for Noble Finance II are the same as the information presented for Noble in all material respects. For the three and nine months ended September 30, 2026, Noble Finance II’s operating income (loss) was $10.3 million and $30.9 million higher, respectively, than that of Noble. The operating income (loss) difference is primarily a result of expenses related to corporate professional and legal costs and administration charges attributable to Noble for operations support and stewardship-related services.

Fair Value of Debt

Fair value represents the amount at which an instrument could be exchanged in a current transaction between willing parties. The estimated fair value of our debt instruments was based on the quoted market prices for similar issues or on the current rates offered to us for debt of similar remaining maturities (Level 2 measurement). The fair value of the Revolving Credit Facility approximates its respective carrying amount as its interest rate is variable and reflective of market rates.

The following table presents the carrying value, net of unamortized debt issuance costs and discounts or premiums, and the estimated fair value of our total debt, not including the effect of unamortized debt issuance costs, respectively:

Note 6 — Revenue and Customers

Disaggregation of Revenue

The following table provides information about contract drilling services revenue by rig types:

Contract Balances

Accounts receivables 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 amortized 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.

The following table provides information about contract assets and contract liabilities from contracts with customers:

Significant changes in the remaining performance obligation contract assets and contract liabilities balances for the nine months ended September 30, 2026 and 2025, are as follows:

Off-market Customer Contract Assets and Liabilities

Off-market customer contract assets and liabilities were recognized in connection with the agreement and plan of merger, dated June 9, 2024, with Diamond Offshore Drilling, Inc. (“Diamond”), Dolphin Merger Sub 1, Inc., and Dolphin Merger Sub 2, Inc., under which Noble acquired Diamond in a stock plus cash transaction (the “Diamond Transaction”), and were included in “Other assets” and “Noncurrent contract liabilities,” respectively.

In connection with the Diamond Transaction, the Company recognized a fair value adjustment of $27.7 million related to certain unfavorable customer contracts acquired. As of June 2025, these liabilities were fully amortized as an increase to contract drilling services revenue from September 4, 2024, through the remainder of the contracts.

Note 7 — Income Taxes

During the three months ended September 30, 2026, the Company recognized discrete net deferred tax expenses of $15.8 million related to releases and adjustments of valuation allowance for deferred tax benefits primarily in Switzerland and Nigeria.

During the nine months ended September 30, 2026, the Company recognized additional net discrete deferred tax benefits of $23.9 million primarily related to releases and adjustments of valuation allowance for deferred tax benefits primarily in Nigeria.

During the three months ended September 30, 2025, the Company recognized additional discrete deferred tax benefits of $6.1 million related to releases and adjustments of valuation allowance for deferred tax benefits in Luxembourg.

During the nine months ended September 30, 2025, the Company recognized additional discrete deferred tax benefits of $85.1 million related to releases and adjustments of valuation allowance for deferred tax benefits in Luxembourg.

In deriving the above net deferred tax benefits or expenses, 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 September 30, 2026, the reserves for uncertain tax positions totaled $118.7 million (net of related tax benefits of $1.0 million). At December 31, 2025, the reserves for uncertain tax positions totaled $119.2 million (net of related tax benefits of $0.9 million).

During the three months ended September 30, 2026, our tax provision included tax expenses of $15.8 million related to adjustments to valuation allowance for deferred tax expenses primarily in Switzerland and recurring quarterly accruals of $117.3 million mostly in Ghana, Guyana, Luxembourg, Switzerland, and the United States.

During the nine months ended September 30, 2026, our tax provision included tax benefits of $23.9 million primarily related to adjustments to valuation allowance for deferred tax benefits primarily in Nigeria. Such tax benefits were offset by tax effects of $23.5 million related to the gain on sale of operating assets and recurring quarterly accruals of $222.7 million mostly in Ghana, Guyana, Luxembourg, Switzerland, and the United States.

Note 8 — Commitments and Contingencies

Tax Matters

Audit claims of approximately $11.0 million at September 30, 2026, attributable to income and other business taxes, remain outstanding and are under continued objection by Noble. Such audit claims 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 nor provide assurance as to the ultimate outcome of any existing or future assessments.

Letters of Credit and Surety Bonds

As of September 30, 2026, we had $6.7 million of letters of credit issued under the Revolving Credit Facility and an additional $110.7 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.

Note 9 — Supplemental Financial Information

Condensed Consolidated Balance Sheets Information

Restricted cash

Noble’s restricted cash balance as of September 30, 2026, and December 31, 2025, was $0.2 million and $8.6 million, respectively. All restricted cash is recorded in “Prepaid expenses and other current assets.”

Leases

Our lease agreements are primarily for real estate, equipment, storage, dock space, and automobiles and are included within “Other assets”, “Other current liabilities”, and “Other liabilities” on our Condensed Consolidated Balance Sheets. In connection with the Diamond Transaction, the Company assumed several finance leases for well control equipment used on the drillships that included an option to purchase the leased equipment at the end of the respective lease term.

During the first quarter of 2026, Noble exercised the option to purchase the leased equipment and entered into a purchase and sale agreement with EFS BOP, LLC, as seller, for the purchase offour blowout preventer (“BOP”) systems. The aggregate purchase price for the equipment is $73.0 million. As of September 30, 2026, we had purchased three of thefour BOP systems, which were reclassified to “Property and equipment” from “Other assets” on our Condensed Consolidated Balance Sheet. The closing for the lone remaining BOP system is due to occur during the fourth quarter of 2026 consistent with the remaining lease term.

Supplemental balance sheet information related to finance leases was as follows:

Notes receivable

On December 8, 2025, Borr Drilling Limited ("Borr”) and Noble entered into a Sale and Purchase Agreement (which was amended on January 5, 2026, the "SPA"), pursuant to which Borr agreed to buy and Noble has agreed to sell five jackup rigs (the "Purchased Rigs") for $360.0 million.

In relation to the SPA, Noble provided a $150.0 million loan to Borr (the "Loan"), with three out of thefive Purchased Rigs (Noble Tom Prosser, Noble Regina Allen, and Noble Resilient) used as collateral. The Loan has the seniority of Subordinated Secured obligation and matures on January 7, 2032, with the interest rate of the Loan changing over time (ranging from 7.5% to 15.0%). Furthermore, interest through the third interest payment may be paid in kind at Borr’s election and the Loan can be prepaid at any time without premium or penalty, with certain provisions mandating prepayment. We initially recorded notes receivable equal to the fair value of the Loan estimated through the use of a discounted cash flow model. In July 2026, Borr exercised the first payment-in-kind interest option, resulting in approximately $5.2 million of accrued interest being capitalized and added to the carrying value of the notes receivable.

In September 2026, the notes receivable met the criteria for classification as held for sale and, thus, the carrying value of the notes receivable was moved to “Prepaid expenses and other current assets.” We adjusted the notes receivable to fair value based on observable market data on similar instruments representative of Level 2 fair value measurements.
