Revenue from Contracts with Customers

Revenue from Contract with Customer [Abstract]  
Revenue from Contract with Customer [Text Block] Revenue from Contracts with Customers
 
Under our drilling contracts with customers, we provide a drilling rig and drilling services, including rig crews, on a day rate contract basis. We receive a daily rate that may vary between the full rate and zero rate throughout the duration of the contractual term, depending on the operations of the rig. We also may receive lump-sum fees or similar compensation generally for the mobilization, demobilization, and capital upgrades of our rigs. Our customers bear substantially all of the costs of constructing the well and supporting drilling operations, as well as the economic risk relative to the success of the well.

Our drilling service provided under each drilling contract is a single performance obligation satisfied over time and comprised of a series of distinct time increments, or service periods. Total revenue is determined for each individual drilling contract by estimating both fixed and variable consideration expected to be earned over the contract term. Fixed consideration generally relates to activities such as mobilization, demobilization and capital upgrades of our rigs that are not distinct performance obligations within the context of our contracts and is recognized on a straight-line basis over the contract term. Variable consideration generally relates to distinct service periods during the contract term and is recognized in the period when the services are performed.

The remaining duration of our drilling contracts based on those in place as of September 30, 2026 was between approximately 1 month and 4 years.
Contract Assets and Liabilities

Contract assets represent amounts recognized as revenue but for which the right to invoice the customer is dependent upon our future performance. Once the previously recognized revenue is invoiced, the corresponding contract asset, or a portion thereof, is transferred to accounts receivable.

Contract liabilities generally represent fees received for mobilization, capital upgrades or in the case of our 50/50 unconsolidated joint venture with Saudi Aramco, represent the difference between the amounts billed under the bareboat charter arrangements and lease revenues earned. See “Note 3 – Equity Method Investment in ARO" for additional details regarding our balances with ARO.

Contract assets and liabilities are presented net on our Condensed Consolidated Balance Sheets on a contract-by-contract basis. Current contract assets and liabilities are included in Other current assets and Accrued liabilities and other, respectively, and noncurrent contract assets and liabilities are included in Other assets and Other liabilities, respectively, on our Condensed Consolidated Balance Sheets.

The following table summarizes our contract assets and contract liabilities (in millions):

Deferred Contract Costs

Costs incurred for upfront rig mobilizations and certain contract preparations are attributable to our future performance obligation under each respective drilling contract. These costs are deferred and amortized on a straight-line basis over the contract term. Deferred contract costs are included in Other current assets and Other assets on our Condensed Consolidated Balance Sheets and totaled $75.8 million and $36.6 million as of September 30, 2026 and December 31, 2025, respectively. During the three and nine months ended September 30, 2026, amortization of such costs totaled $18.1 million and $50.6 million, respectively. During the three and nine months ended September 30, 2025, amortization of such costs totaled $9.1 million and $30.7 million, respectively.
Deferred Certification Costs

We must obtain certifications from various regulatory bodies in order to operate our drilling rigs and must maintain such certifications through periodic inspections and surveys. The costs incurred in connection with maintaining such certifications, including inspections, tests, surveys and drydock, and other compliance costs, are deferred and amortized on a straight-line basis over the corresponding certification periods. Deferred regulatory certification and compliance costs were included in Other current assets and Other assets on our Condensed Consolidated Balance Sheets and totaled $7.1 million and $7.6 million as of September 30, 2026 and December 31, 2025, respectively. During the three and nine months ended September 30, 2026, amortization of such costs totaled $1.4 million and $5.1 million, respectively. During the three and nine months ended September 30, 2025, amortization of such costs totaled $1.9 million and $6.3 million, respectively.

Future Amortization of Contract Liabilities and Deferred Costs

The table below reflects the expected future amortization of our contract liabilities and deferred costs recorded as of September 30, 2026. In the case of our contract liabilities related to our bareboat charter arrangements with ARO, the contract liability is not amortized and as such, the amount is reflected in the table below at the end of the current lease term.

Equity Method Investments and Joint Ventures [Abstract]  
Equity Method Investment In ARO Equity Method Investment in ARO
Background
    
ARO is a 50/50 unconsolidated joint venture between the Company and Saudi Aramco that owns and operates jackup drilling rigs in Saudi Arabia. As of September 30, 2026, ARO owned nine jackup rigs, had ordered four newbuild jackup rigs and leased seven rigs from us through bareboat charter arrangements (the "Lease Agreements") whereby substantially all operating costs are incurred by ARO.

The shareholder agreement governing the joint venture (the "Shareholder Agreement") specifies that ARO shall purchase 20 newbuild jackup rigs. Under this program, two newbuild jackups have been built and are in service, two are currently under construction (Kingdom 3 and Kingdom 4, which were ordered in October 2024 and November 2025, respectively) and two additional newbuild jackups were ordered in August 2026 (Kingdom 5 and Kingdom 6). In connection with these plans, we have a potential obligation to fund ARO for newbuild jackup rigs. See "Note 11 - Contingencies" for additional information.

Equity in earnings (losses) of ARO

We account for our interest in ARO using the equity method of accounting and only recognize our portion of ARO's net income (loss), adjusted for basis differences as discussed below, which is included in Equity in earnings (losses) of ARO in our Condensed Consolidated Statements of Operations.
Our equity method investment in ARO was recorded at its estimated fair value in fresh start accounting upon emergence from bankruptcy in 2021. We computed the difference between the fair value of ARO's net assets and the carrying value of those net assets in ARO's U.S. GAAP financial statements ("basis differences") at that date. These basis differences primarily related to ARO's long-lived assets and the recognition of intangible assets associated with certain of ARO's drilling contracts that were determined to have favorable terms relative to market terms as of the measurement date.

Basis differences are amortized over the remaining life of the assets or liabilities to which they relate and are recognized as an adjustment to the Equity in earnings (losses) of ARO in our Condensed Consolidated Statements of Operations. The amortization of those basis differences is combined with our 50% interest in ARO's net income (loss). A reconciliation of those components is presented below (in millions):

Amortization of basis differences3.1 3.2 9.4 9.5 
Equity in earnings (losses) of ARO$(3.5)$4.4 $13.9 $5.9 
(1) The 50% interest in ARO net income for the nine months ended September 30, 2026 includes the recognition of $14.3 million in additional income, which represents our proportionate share of adjustments recorded by ARO during the completion of its 2025 financial statements subsequent to the issuance of our Annual Report.

Revenues recognized by us related to the Lease Agreements are included within Revenues (exclusive of reimbursable revenues) and revenues related to certain reimbursable expenses in accordance with the Lease Agreements are recognized within Reimbursable revenues in our Condensed Consolidated Statements of Operations and were as follows (in millions):

(1)The per day bareboat charter amount in the Lease Agreements is subject to adjustment based on actual performance of the respective rig and therefore, the corresponding contract assets and contract liabilities are subject to adjustment during the lease term. Upon completion of the lease term, such amounts become a payable to or a receivable from ARO. In addition, the accounts payable balance includes amounts owed to ARO for certain reimbursable costs.

During 2017 and 2018, the Company contributed assets to ARO in exchange for a 10-year shareholder notes receivable due from ARO (the "Notes Receivable from ARO"), which bear interest based on a one-year term Secured Overnight Financing Rate ("SOFR"), set as of the end of the year prior to the applicable year, plus 2.10%. The Notes Receivable from ARO were adjusted to their estimated fair value in fresh start accounting in 2021 and the resulting discount to the principal amount is being amortized using the effective interest method to interest income over the remaining terms of the notes.

While taking into account certain restrictions on the sales of assets under our Indenture dated as of April 19, 2023 and within the Business Combination Agreement, as part of our strategy, we may act opportunistically from time to time to sell assets to enhance shareholder value. Gains and losses recognized on sale of assets are recognized in Other, net on the Condensed Consolidated Statements of Operations. Additionally, we may consider retiring assets that no longer meet our standards for economic returns. Non-cash losses on impairment and any gains on remeasurement of assets held for sale are recognized within Other operating (income) loss on the Condensed Consolidated Statements of Operations.

Sale of VALARIS 111

In September 2026, we entered into an agreement to sell VALARIS 111, a rig within our Jackups segment, for recycling for $1.7 million. Under the terms of the agreement, we retained the right to terminate the purchase and sale agreement within 30 days following receipt of the proceeds. On September 30, 2026, we completed the sale and received $1.7 million of cash proceeds. As of September 30, 2026, the net book value of the rig was classified as held for sale due to the cancellation option.

In October 2026, we entered into an agreement to sell the rig to another buyer for conversion to a mobile offshore production unit for cash proceeds of $10.5 million. As such, we rescinded the purchase and sale agreement with the initial buyer and made a payment of approximately $3.0 million in accordance with the termination provisions within the agreement. The sale to the new buyer was completed in October and we recognized a pre-tax gain of approximately $8.0 million in the fourth quarter.
Sale of VALARIS MS-1

In September 2026, we entered into an agreement to sell VALARIS MS-1, our only remaining semisubmersible rig within our Floaters segment, for recycling for total cash proceeds of $11.0 million. In connection with this sale, we recognized a non-cash loss on impairment of $3.0 million during the three months ended September 30, 2026 and the rig was removed from service.

Sale of VALARIS 109

In July 2026, we sold VALARIS 109, a rig within our Jackups segment. The rig was sold for cash proceeds of $34.0 million, resulting in the recognition of a pre-tax gain of $31.3 million in the third quarter of 2026.

Sale of VALARIS 104

In June 2026, we sold VALARIS 104, a rig within our Jackups segment, for alternative use. The rig was sold for cash proceeds of $40.0 million, resulting in the recognition of a pre-tax gain of $36.6 million in the second quarter of 2026.

Sale of VALARIS DPS-1

In the fourth quarter of 2025, we approved a plan to retire VALARIS DPS-1, a semisubmersible rig within our Floaters segment. VALARIS DPS-1 was reclassified from Property and equipment, net to Assets held for sale on our Consolidated Balance Sheets during the fourth quarter of 2025.

In connection with the held-for-sale classification of VALARIS DPS-1, we recognized a non-cash loss on impairment of $15.8 million during 2025, resulting in a $6.4 million carrying value as of December 31, 2025, which was determined using a probability-weighted market approach based on transactions involving comparable assets, non-binding independent broker quotes and management assumptions, all of which were considered Level 3 inputs due to the level of estimation involved.

Assets held for sale are remeasured at each reporting period for changes in estimated fair value less costs to sell, however, any related gains recognized cannot exceed the previous impairment losses taken for the specified disposal group. As such, we reassessed the fair value of VALARIS DPS-1 during the first quarter of 2026 utilizing a market approach based on a preliminary sale agreement, which was considered a Level 3 input due to the level of estimation involved since the sale had not yet been completed at the time of our analysis. In connection with this, we recognized a $2.8 million gain on remeasurement of our asset held for sale during the first quarter of 2026.

In the second quarter of 2026, VALARIS DPS-1 was sold for recycling and removed from service for total cash proceeds of $10.1 million. No additional gain or loss was recognized upon completion of this sale.

Sale of VALARIS 247

In the third quarter of 2025, we sold VALARIS 247, a rig within our Jackups segment, and collected cash proceeds of approximately $108.0 million. We recognized a pre-tax gain of $88.4 million in connection with the sale.
Sale of Other Retired Semis

In the first quarter of 2025, we approved a plan to retire three semisubmersible rigs within our Floaters segment, VALARIS DPS-3, VALARIS DPS-5, and VALARIS DPS-6 (collectively, the “Retired Semis”). In April 2025, the Retired Semis were sold for recycling and permanently removed from service for total cash proceeds of $10.0 million.

In connection with the retirement of the Retired Semis, during the first quarter of 2025, we recognized a non-cash loss on impairment of $7.8 million, which represented the amount of carrying value that exceeded the disposal group's aggregate fair value less costs to sell. We estimated the fair value using a market approach based on the preliminary sale agreement for the Retired Semis, which is considered a Level 3 input due to the level of estimation involved since the sale had not yet been completed at the time of our analysis.

Sale of VALARIS 75

In the first quarter of 2025, VALARIS 75, a rig within our Jackups segment which had an immaterial net book value, was sold resulting in a pre-tax gain on sale of $23.0 million. Of the proceeds, $14.0 million was collected upon closing, $5.0 million was collected in January 2026 and the remaining $5.0 million is expected to be received on the second anniversary of the closing.

Sale of Angola Office Building

In the first quarter of 2025, we sold an office building in Angola for cash proceeds of $5.2 million, resulting in a pre-tax gain on sale of $4.0 million. Of the proceeds, approximately $2.5 million was collected during the fourth quarter of 2024 and $2.7 million was collected during the first quarter of 2025.

Earnings Per Share Earnings Per Share
 
Basic earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period. Weighted-average shares outstanding used in our computation of diluted EPS is calculated using the treasury stock method and includes the effect of all potentially dilutive stock equivalents, including warrants, restricted stock unit awards and performance stock unit awards.
The following table is a reconciliation of the weighted-average shares used in our basic and diluted EPS computations for the three and nine months ended September 30, 2026 and 2025 (in millions), except per share amounts:

Anti-dilutive shares totaling 227,000 and 258,000 were excluded from the computation of diluted EPS for the three and nine months ended September 30, 2025, respectively.

We had 5,470,742 warrants outstanding (the "Warrants") as of September 30, 2026 to purchase common shares of Valaris Limited (the "Common Shares"), which are exercisable for one Common Share per Warrant at an initial exercise price of $131.88 per Warrant and expire on April 29, 2028. The exercise of these Warrants into Common Shares would have a dilutive effect to the holdings of Valaris Limited's existing shareholders. These Warrants are anti-dilutive for all periods presented.

2030 Second Lien Notes

In April 2023, the Company and Valaris Finance Company LLC (“Valaris Finance”), a wholly-owned subsidiary, issued and sold, at par, $700.0 million aggregate principal amount of Second Lien Notes (the "Initial Second Lien Notes"). In August 2023, the Company and Valaris Finance issued, at 100.75% of par, an additional $400.0 million aggregate principal amount of Second Lien Notes (the "Additional Notes"). The Initial Second Lien Notes and the Additional Notes form a single series and are collectively referred to as the "2030 Second Lien Notes."

The 2030 Second Lien Notes were issued under the Indenture, dated as of April 19, 2023 (the "Indenture"), and will mature on April 30, 2030. The 2030 Second Lien Notes bear an interest rate of 8.375% per annum and interest is payable semi-annually in arrears on April 30 and October 30 of each year. The 2030 Second Lien Notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by certain subsidiaries of the Company.

As of September 30, 2026, we were in compliance in all material respects with our covenants under the Indenture.
2028 Credit Agreement

In April 2023, the Company entered into a senior secured revolving credit agreement (the “2028 Credit Agreement”) which provides for commitments permitting borrowings of up to $375.0 million. Permitted borrowings under the 2028 Credit Agreement may be increased, subject to the agreement of lenders to provide such additional commitments and the satisfaction of certain conditions, by an additional $200.0 million pursuant to the terms of the 2028 Credit Agreement, and includes a $150.0 million sublimit for the issuance of letters of credit. Valaris Finance and certain other subsidiaries of the Company guarantee the Company's obligations under the 2028 Credit Agreement, and the lenders have a first priority lien on the assets securing the 2028 Credit Agreement. The 2028 Credit Agreement is scheduled to mature on April 3, 2028.

Amounts borrowed under the 2028 Credit Agreement are subject to an interest rate per annum equal to, at our option, either (a) a base rate determined as the greatest of (i) a prime rate, (ii) the federal funds rate plus 0.5% and (iii) Term SOFR (as defined in the 2028 Credit Agreement) for a one month interest period plus 1.1% (such base rate to be subject to a 1% floor) or (b) Term SOFR plus 0.10% (subject to a 0% floor), plus, in each case of clauses (a) and (b) above, an applicable margin ranging from 1.50% to 3.00% and 2.50% to 4.00%, respectively, based on the credit ratings that are one notch higher than the corporate family ratings provided by Standard & Poor’s Financial Services LLC (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”) with respect to Valaris Limited.

Additionally, we are required to pay a quarterly commitment fee to the lenders under the 2028 Credit Agreement with respect to the average daily unutilized commitments thereunder at a rate ranging from 0.375% to 0.75% depending on the credit ratings that are one notch higher than the corporate family ratings provided by S&P and Moody’s with respect to Valaris Limited. With respect to each letter of credit issued pursuant to the 2028 Credit Agreement, we are required to pay a letter of credit fee equal to the applicable margin in effect for Term SOFR loans and a fronting fee in an amount to be mutually agreed between us and the issuer of such letter of credit.

As of September 30, 2026, we were in compliance in all material respects with our covenants under the 2028 Credit Agreement. We had no amounts outstanding under the 2028 Credit Agreement as of September 30, 2026.

Share Repurchase Program

Our board of directors has authorized a share repurchase program (the "Share Repurchase Program") under which we may purchase up to $600.0 million of our outstanding Common Shares. The Share Repurchase Program does not have a fixed expiration, may be modified, suspended or discontinued at any time and any repurchases made pursuant to the Share Repurchase Program are subject to compliance with applicable covenants and restrictions under our financing agreements and the Business Combination Agreement.

There were no share repurchases during each of the three and nine months ended September 30, 2026. The following table summarizes shares repurchased, aggregate cost and the average per share price (in millions, except average per share price) for the three and nine months ended September 30, 2025:

Components of Income Tax Expense (Benefit), Continuing Operations [Abstract]  
Income Taxes Income Taxes
 
We calculate our tax provision by applying the estimated annual effective tax rate for the full fiscal year to pre-tax income or loss, excluding discrete items. The consolidated effective tax rate for the three and nine months ended September 30, 2026, excluding the impact of discrete tax items, was 20.1% and 21.1%, respectively. The discrete tax expense for these periods primarily related to rig sales, partially offset by the resolution of prior period tax matters. See "Note 5 - Property and Equipment" for further disclosures regarding rigs sold during the period.

The consolidated effective tax rate for the three and nine months ended September 30, 2025, excluding the impact of discrete tax items, was 14.1% and 14.8%, respectively. The discrete tax items for the nine months ended September 30, 2025, primarily related to the establishment of the valuation allowance on deferred tax assets. During the first quarter of 2025, we recognized $168.8 million of deferred tax expense related to the establishment of this valuation allowance, which resulted from a change in estimated future taxable income in a certain operating jurisdiction in connection with the retirement of the Retired Semis. We intend to maintain this valuation allowance until there is sufficient evidence to support a reversal of the allowance. The timing and amount of future valuation allowance reductions are subject to future levels of contracting and profitability achieved or by the expiration of the related deferred tax assets. See "Note 5 - Property and Equipment" for further disclosure regarding the Retired Semis.

Malaysia Tax Assessment

In February 2024, one of our Malaysian subsidiaries received an unfavorable court decision regarding a tax assessment for the 2012-2017 tax years totaling approximately MYR117.0 million (approximately $29.0 million converted at current quarter-end exchange rates), including a late payment penalty. In July 2024, we received a payment demand from the Malaysian tax authority for the full assessment amount. In order to further contest the assessment, we made payments of approximately $8.0 million and $18.0 million in the first quarter of 2025 and in 2024, respectively, for aggregate total payments of $26.0 million. These payments are included within Other assets in the Condensed Consolidated Balance Sheets. We have not recorded a liability for uncertain tax positions as of September 30, 2026, related to this assessment based on a more-likely-than-not threshold. We believe our tax returns are materially correct as filed and will vigorously contest this assessment.

Australian Tax Assessment

In December 2024, we reached a settlement agreement with the Australian tax authorities regarding tax assessments which related to the examination of certain of our tax returns for the years 2011 through 2016. In connection with this agreement, during the first quarter of 2025, we received refunds (including interest) totaling A$42.0 million (approximately $26.0 million at then-current exchange rates).

ARO Newbuild Funding Obligations

In connection with our 50/50 unconsolidated joint venture, we have a potential obligation to fund ARO for newbuild jackup rigs. The Shareholder Agreement specifies that ARO shall purchase 20 newbuild jackup rigs. The joint venture partners intend for the newbuild jackup rigs to be financed out of available cash on hand and from ARO's operations and/or funds available from third-party financing. The first two newbuild jackups, Kingdom 1 and Kingdom 2, were delivered and commenced operations in 2023 and 2024, respectively.
In October 2024 and November 2025, ARO ordered the third and fourth newbuild jackups, Kingdom 3 and Kingdom 4, respectively, for a purchase price of approximately $300.0 million each. ARO paid a 25% down payment from cash on hand for Kingdom 3 and Kingdom 4. In August 2026, ARO ordered the fifth and sixth newbuild jackups, Kingdom 5 and Kingdom 6, for a purchase price of approximately $360.0 million each, with each order requiring a 25% down payment. ARO paid $45.0 million, representing 50% of the required down payment for Kingdom 5, using a combination of cash on hand and borrowings under ARO's revolving credit facility. The remaining $45.0 million down payment for Kingdom 5 and the full $90.0 million down payment for Kingdom 6 are expected to be paid in the fourth quarter of 2026 with cash from third-party financing or additional borrowings under ARO's revolving credit facility. The final payment for each newbuild rig will be due upon delivery.

In the event ARO has insufficient cash or is unable to obtain third-party financing, each partner may periodically be required to make additional capital contributions to ARO, up to a maximum aggregate contribution of $1.25 billion from each partner to fund the newbuild program. Beginning with the delivery of the second newbuild, each partner's commitment is reduced by the lesser of the actual cost of each newbuild rig or $250.0 million, on a proportionate basis. Following the delivery of Kingdom 2, our commitment to fund the newbuild program has been reduced to $1.1 billion.

Letters of Credit and Surety Bonds

In the ordinary course of business with customers and others, we have entered into letters of credit and surety bonds to guarantee our performance as it relates to our drilling contracts, contract bidding, customs duties, tax appeals and other obligations in various jurisdictions. Letters of credit and surety bonds outstanding as of September 30, 2026 totaled $113.7 million and are issued under facilities provided by various banks and other financial institutions, but none were issued under the 2028 Credit Agreement. Obligations under these letters of credit and surety bonds are not normally called, as we typically comply with the underlying performance requirements. As of September 30, 2026, we had collateral deposits in the amount of $14.8 million with respect to these agreements.

Other Matters

In addition to the foregoing, we are named defendants or parties in certain other lawsuits, claims or proceedings incidental to our business and are involved from time to time as parties to governmental investigations or proceedings, including matters related to taxation, arising in the ordinary course of business. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we do not expect these matters to have a material adverse effect on our financial position, operating results and cash flows.

Segment Reporting, Revenue [Abstract]  
Segment Information Segment Information
 
Our business consists of four operating segments: (1) Floaters, which includes our drillships and semisubmersible rigs, (2) Jackups, (3) ARO and (4) Other, which consists of management services on rigs owned by third parties and the activities associated with our arrangements with ARO under the Lease Agreements. Floaters, Jackups and ARO are also reportable segments.

Our chief operating decision maker ("CODM") assesses segment performance based on their review of the operating income (loss) of each segment, which measures profitability after deducting normal operating costs. Components within operating income (loss), such as revenues and contract drilling expenses, are used to monitor actual performance against budget and monthly forecasted results for each segment. Further, the CODM utilizes revenue to derive a segment’s asset utilization, average daily revenue and revenue efficiency. Using these metrics, the CODM can identify potentially underperforming segments and develop strategies to increase profits or reduce costs, make investment decisions and allocate resources as needed. The disaggregated segment information, as presented in the tables below, aligns with the segment level information that is regularly provided to the CODM.
Our onshore support costs included within Contract drilling expenses are not allocated to our operating segments for purposes of measuring segment operating income (loss) and as such, those costs are included in “Reconciling Items.” Further, General and administrative expenses, Depreciation expense and Merger and integration expenses incurred by our corporate office are not allocated to our operating segments for purposes of measuring segment operating income (loss) and are included in "Reconciling Items." We measure segment assets as Property and equipment, net.

The full operating results included below for ARO are not included within our consolidated results and thus are deducted under "Reconciling Items" and replaced with our equity in earnings (losses) of ARO. See "Note 3 - Equity Method Investment in ARO" for additional information on ARO and related arrangements. Similarly, the Property and equipment, net balances presented below for ARO are not included within our Condensed Consolidated Balance Sheets and thus are also deducted under "Reconciling Items."

Concentration of Risk

Credit Risk - We are exposed to credit risk relating to our cash and cash equivalents and receivables from customers. Our cash and cash equivalents are primarily held by various well-capitalized and credit-worthy financial institutions. We monitor the credit ratings of these institutions and limit the amount of exposure to any one institution and therefore, do not believe a significant credit risk exists for these balances. We mitigate our credit risk relating to receivables from customers, which consist primarily of major international, government-owned and independent oil and gas companies, by performing ongoing credit evaluations. We also maintain reserves for potential credit losses, which generally have been within our expectations.
Customer Concentration - Consolidated revenues with customers that individually contributed 10% or more of revenue in either of the three and nine months ended September 30, 2026 and 2025 were as follows:

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Accounting, Policy Unaudited Condensed Consolidated Financial Statements
 
We prepared the accompanying condensed consolidated financial statements of Valaris Limited and its subsidiaries (the "Company," "Valaris," "our," "we" or "us") in accordance with accounting principles generally accepted in the United States of America ("GAAP"), pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") included in the instructions to Form 10-Q and Article 10 of Regulation S-X. The financial information included in this report is unaudited but, in our opinion, includes all adjustments (consisting of normal recurring adjustments) that are necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. The December 31, 2025 Condensed Consolidated Balance Sheet data was derived from our 2025 audited consolidated financial statements but does not include all disclosures required by GAAP. The preparation of our condensed consolidated financial statements requires us to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the related revenues and expenses and disclosures of gain and loss contingencies as of the date of the financial statements. Actual results could differ from those estimates.

Results of operations for the three and nine months ended September 30, 2026 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2026, or for any future period. We recommend these condensed consolidated financial statements be read in conjunction with our annual report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 20, 2026 (our "Annual Report").

Pending Business Combination with Transocean

On February 9, 2026, we entered into a business combination agreement (the "Business Combination Agreement") with Transocean Ltd., a Swiss corporation ("Transocean"), under which Transocean will acquire all of the issued and outstanding common shares of Valaris in exchange for shares of Transocean at an exchange ratio of 15.235 Transocean shares for each common share of Valaris (the "Business Combination"). In addition, Warrants that are outstanding as of immediately prior to the transaction closing date will be assumed by Transocean and remain outstanding and be exercisable for the Fundamental Transaction Consideration (as defined in the Warrant Agreement, dated as of April 30, 2021, by and between Valaris and the warrant agent named therein) multiplied by the number of Valaris common shares for which each warrant is exercisable immediately prior to the transaction closing date. The Business Combination will be effected by way of a court-approved scheme of arrangement between Valaris and the holders of the Valaris common shares pursuant to section 99 of the Companies Act 1981 of Bermuda, as amended. Upon completion and on a fully diluted basis assuming conversion to shares of Transocean’s exchangeable bonds due 2029, Transocean shareholders would own approximately 53% of the combined company, with Valaris shareholders owning the remaining 47%.

Completion of the Business Combination is subject to customary closing conditions, including (i) the receipt of the requisite approvals of the Valaris shareholders and the Transocean shareholders, (ii) the granting of the sanction order on terms consistent with the Business Combination Agreement, (iii) the Transocean shares issued pursuant to the Business Combination Agreement having been approved for listing on the NYSE, subject to official notice of issuance, (iv) certain regulatory approvals having been obtained or any applicable waiting period having expired or been terminated (which is expected to be satisfied by November 3, 2026), (v) no governmental authority within applicable jurisdictions having enacted or issued any law or order preventing or prohibiting the consummation of the Business Combination and (vi) the absence of a Transocean Material Adverse Effect or a Valaris Material Adverse Effect (each as defined within the Business Combination Agreement). Under certain specified circumstances in which the Business Combination Agreement is terminated, we would be required to pay to Transocean a termination fee equal to $173.0 million.
Shareholder meetings for both Valaris and Transocean are scheduled for November 24, 2026, and a hearing before the Supreme Court of Bermuda to sanction the Business Combination is scheduled for November 26, 2026. Subject to receipt of the requisite shareholder and court approvals, and satisfaction of the remaining closing conditions, the Business Combination is expected to close on or about December 1, 2026.

In connection with the Business Combination, we incurred professional fees and other costs of $15.5 million and $40.5 million for the three and nine months ended September 30, 2026, respectively, which are included within Merger and integration expenses in the Condensed Consolidated Statements of Operations.

Summary of Significant Accounting Policies

Certain previously reported amounts have been reclassified to conform to the current year presentation.

New Accounting Pronouncements

Accounting Pronouncements to be Adopted

Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures - 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 ("Update 2024-03"), which requires companies to disclose additional information for certain relevant expense categories in the Statements of Operations and within the notes to the financial statements. Update 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted and can be applied either prospectively to financial statements issued for reporting periods after the effective date, or retrospectively to prior periods which are presented in the financial statements. We are currently assessing the impact of the requirements on our condensed consolidated financial statements and disclosures, but do not expect the adoption of Update 2024-03 to result in a change in recognition or measurement of expenses within our consolidated financial statements.
With the exception of the updated standard discussed above, there have been no accounting pronouncements issued and not yet effective that have significance, or potential significance, to our condensed consolidated financial statements.
