Statements contained in this report that are not historical facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking statements include words or phrases such as "anticipate," "believe," "estimate," "expect," "intend," "likely," "plan," "project," "could," "may," "might," "should," "will" and similar words and specifically include statements regarding expected financial performance; expected utilization, day rates, revenues, operating expenses, cash flows, contract status, terms and duration, contract backlog, capital expenditures, insurance, financing and funding; the offshore drilling market, including supply and demand, customer drilling programs, stacking of rigs, effects of new rigs on the market and effect of the volatility of commodity prices; expected work commitments, awards, contracts and letters of intent; the availability, delivery, mobilization, contract commencement or relocation or other movement of rigs and the timing thereof; rig reactivations, enhancement, upgrade or repair and timing and cost thereof; the suitability of rigs for future contracts; performance of our joint ventures, including our joint venture with Saudi Arabian Oil Company ("Saudi Aramco"); timing of the delivery of the Saudi Aramco Rowan Offshore Drilling Company ("ARO") newbuild rigs and the timing of additional ARO newbuild orders; divestitures of assets; general market, business and industry conditions, trends and outlook; general political conditions, including political tensions, conflicts and war (such as the ongoing conflict in Ukraine); the impacts and effects of public health crises, pandemics and epidemics; future operations; any exercise of our options for delivery of the VALARIS DS-13 and VALARIS DS-14; the impact of increasing regulatory complexity; the outcome of tax disputes, assessments and settlements; expense management; and the likely outcome of litigation, legal proceedings, investigations or insurance or other claims or contract disputes and the timing thereof.

Such statements are subject to numerous risks, uncertainties and assumptions that may cause actual results to vary materially from those indicated, including:

•delays in contract commencement dates or cancellation, suspension, renegotiation or termination with or without cause of drilling contracts or drilling programs as a result of general or industry-specific economic conditions, mechanical difficulties, performance, delays in the delivery of critical drilling equipment, failure of the customer to receive final investment decision (FID) for which the drilling rig was contracted or other reasons;

•changes in worldwide rig supply and demand, competition or technology, including as a result of delivery of newbuild drilling rigs or reactivation of stacked drilling rigs;

•general economic and business conditions, including recessions, inflation, volatility affecting the banking system and financial markets and adverse changes in the level of international trade activity;

•requirements to make significant expenditures in connection with rig reactivations, customer drilling requirements and to comply with governing laws or regulations in the regions we operate;

•loss of a significant customer or customer contract, as well as customer consolidation and changes to customer strategy, including focusing on renewable energy projects;

•our ability to attract and retain skilled personnel on commercially reasonable terms, whether due to labor regulations, rising wages, unionization, or otherwise, or to retain employees;

•the occurrence of cybersecurity incidents, attacks or other breaches to our information technology systems, including our rig operating systems;

drilling limitations and other delays due to severe storms and hurricanes and the limited availability or high cost of insurance coverage for certain offshore perils, such as hurricanes in the Gulf of Mexico or associated removal of wreckage or debris;

•our customers cancelling or shortening the duration of our drilling contracts, cancelling future drilling programs and seeking pricing and other contract concessions from us;

•decreases in levels of drilling activity and capital expenditures by our customers, whether as a result of the global capital markets and liquidity, prices of oil and natural gas, changes in tax policy (such as the U.K.’s windfall tax on oil and gas producers in the British North Sea), climate change concerns or otherwise, which may cause us to idle, stack or retire additional rigs;

•impacts and effects of public health crises, pandemics and epidemics, the related public health measures implemented by governments worldwide, the duration and severity of the outbreak and its impact on global oil demand, the volatility in prices for oil and natural gas and the extent of disruptions to our operations;

•disruptions to the operations and business of our key customers, suppliers and other counterparties, including impacts affecting our supply chain and logistics;

•governmental action, terrorism, cyber-attacks, piracy, military action and political and economic uncertainties, including civil unrest, political demonstrations, mass strikes, or an escalation or additional outbreak of armed hostilities or other crises in oil or natural gas producing areas of the Middle East, North Africa, West Africa, Southeast Asia, Eastern Europe or other geographic areas, which may result in expropriation, nationalization, confiscation or deprivation or destruction of our assets; suspension and/or termination of contracts based on force majeure events or adverse environmental safety events; or volatility in prices of oil and natural gas;

•disputes over production levels among members of the Organization of Petroleum Exporting Countries and other oil and gas producing nations (“OPEC+”), which could result in increased volatility in prices for oil and natural gas that could affect the markets for our services;

•our ability to enter into, and the terms of, future drilling contracts, including contracts for newbuild rigs or acquired rigs, for rigs currently idled and for rigs whose contracts are expiring;

•any failure to execute definitive contracts following announcements of letters of intent, letters of award or other expected work commitments;

•the outcome of litigation, legal proceedings, investigations or other claims or contract disputes, including any inability to collect receivables or resolve significant contractual or day rate disputes, and any renegotiation, nullification, cancellation or breach of contracts with customers or other parties;

•internal control risk due to changes in management, hiring of employees, employee reductions and our shared service center;

•governmental regulatory, legislative and permitting requirements affecting drilling operations, including limitations on drilling locations, limitations on new oil and gas leasing in U.S. federal lands and waters, and regulatory measures to limit or reduce greenhouse gas emissions;

•governmental policies that could reduce demand for hydrocarbons, including mandating or incentivizing the conversion from internal combustion engine powered vehicles to electric-powered vehicles;

•forecasts or expectations regarding the global energy transition, including consumer preferences for alternative fuels and electric-powered vehicles, as part of the global energy transition;

•increased scrutiny from regulators, market and industry participants, stakeholders and others in regard to our environmental, social and governance ("ESG") practices and reporting;

•our ability to achieve our ESG aspirations, targets, goals and commitments, including our Scope 1 emissions intensity reduction target, or the impact of any changes in our ESG strategy or commitments;

2

•potential impacts on our business resulting from climate-change or greenhouse gas legislation or regulations, and the impact on our business from climate-change related physical changes or changes in weather patterns;

•new and future regulatory, legislative or permitting requirements, future lease sales, changes in laws, rules and regulations that have or may impose increased financial responsibility, additional oil spill abatement contingency plan capability requirements and other governmental actions that may result in claims of force majeure or otherwise adversely affect our existing drilling contracts, operations or financial results;

•environmental or other liabilities, risks, damages or losses, whether related to storms, hurricanes or other weather-related events (including wreckage or debris removal), collisions, groundings, blowouts, fires, explosions, cyberattacks, terrorism or otherwise, for which insurance coverage and contractual indemnities may be insufficient, unenforceable or otherwise unavailable;

•tax matters, including our effective tax rates, tax positions, results of audits, changes in tax laws, treaties and regulations, tax assessments and liabilities for taxes;

•our ability to realize the expected benefits of our joint venture with Saudi Aramco, including our ability to fund any required capital contributions or to enforce any payment obligations of the joint venture pursuant to outstanding shareholder notes receivable and benefits of our other joint ventures;

•the potentially dilutive impacts of warrants issued pursuant to the plan of reorganization;

•the costs, disruption and diversion of our management's attention associated with campaigns by activist securityholders; and

•adverse changes in foreign currency exchange rates.

VALARIS LIMITED AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 -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, 2022 Condensed Consolidated Balance Sheet data was derived from our 2022 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, 2023 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2023, 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, 2022, filed with the SEC on February 21, 2023 (our "Annual Report").

Summary of Significant Accounting Policies

Please refer to "Note 1. Description of the Business and Summary of Significant Accounting Policies" of our Consolidated Financial Statements from our Annual Report for the discussion of our significant accounting policies. Certain previously reported amounts have been reclassified to conform to the current year presentation.

New Accounting Pronouncements

Recently adopted accounting pronouncements

Business Combinations - In October 2021, the FASB issued ASU No. 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” (“Update 2021-08”). ASU No. 2021-08 requires an entity (acquirer) to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 and provides practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. The amendments also apply to contract assets and contract liabilities from other contracts to which the provisions of Topic 606 apply, such as contract liabilities for the sale of nonfinancial assets within the scope of Subtopic 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets. The FASB issued the update to improve the accounting for acquired revenue contracts with customers in a business combination. Update 2021-08 is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption permitted. We adopted Update 2021-08 effective January 1, 2023 with no material impact to our condensed consolidated financial statements upon adoption.

9

Accounting pronouncements to be adopted

Reference Rate Reform - In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("Update 2020-04"), which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in Update 2020-04 apply only to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, for which an entity has elected certain optional expedients and that are retained through the end of the hedging relationship. The provisions in Update 2020-04 are effective upon issuance and can be applied prospectively through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, to extend the temporary accounting rules under Topic 848 from December 31, 2022, to December 31, 2024. Our long-term notes receivable from ARO, from which we generate interest income on a LIBOR-based rate (the "Notes Receivable from ARO"), are impacted by the application of this standard. As the Notes Receivable from ARO bear interest on the LIBOR rate determined at the end of the preceding year, the rate governing our interest income in 2023 has already been determined. We expect to be able to modify the terms of our Notes Receivable from ARO to a comparable interest rate before the applicable LIBOR rate is no longer available and as such, do not expect this standard to have a material impact to our condensed consolidated financial statements.

With the exception of the updated standards 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.

Note 2 -Revenue from Contracts with Customers

Our drilling contracts with customers provide a drilling rig and drilling services on a day rate contract basis. Under day rate contracts, we provide a drilling rig and rig crews for which 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, 2023 was between approximately 1 month and 5 years.

Contract Termination - VALARIS DS-11

In 2021, a contract was awarded to VALARIS DS-11 for a project in the U.S. Gulf of Mexico that was expected to commence in mid-2024. In June 2022, the customer terminated the contract. As a result of the contract termination, we received an early termination fee of $51.0 million which is included in revenues on our Condensed Consolidated Statements of Operations for the nine months ended September 30, 2022.

10

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):

	September 30, 2023		December 31, 2022
Current contract assets	$	0.5	$	4.6

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 were included in Other current assets and Other assets on our Condensed Consolidated Balance Sheets and totaled $84.9 million and $57.3 million as of September 30, 2023 and December 31, 2022, respectively. During the three and nine months ended September 30, 2023, amortization of such costs totaled $25.0 million and $62.7 million, respectively. During the three and nine months ended September 30, 2022, amortization of such costs totaled $18.8 million and $41.0 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

11

maintaining such certifications, including inspections, tests, surveys and drydock, as well as remedial structural work 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 $17.9 million and $16.2 million as of September 30, 2023 and December 31, 2022, respectively.

Note 3 -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, 2023, ARO owns seven jackup rigs, has two newbuild jackup rigs on order, and leases eight rigs from us through bareboat charter arrangements (the "Lease Agreements") whereby substantially all operating costs are incurred by ARO.

ARO has plans to purchase 20 newbuild jackup rigs over an approximate 10-year period. In January 2020, ARO ordered the first two newbuild jackups, the first of which was delivered in October 2023 and the second is expected to be delivered in the first quarter of 2024. ARO is expected to place orders for two additional newbuild jackups in the near term. In connection with these plans, we have a potential obligation to fund ARO for newbuild jackup rigs. See "Note 11 - Contingencies" for additional information.

Summarized Financial Information

The operating revenues of ARO presented below reflect revenues earned under drilling contracts with Saudi Aramco for the ARO-owned jackup rigs as well as the rigs leased from us. Contract drilling expense is inclusive of the bareboat charter fees for the rigs leased from us. See additional discussion below regarding these related-party transactions.

Equity in Earnings 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, adjusted for basis differences as discussed below, in Equity in earnings 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 the chapter 11 cases on April 30, 2021 (the "Effective Date") and also on the date of our 2019 transaction where we acquired the subsidiary that held the joint venture interest. 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") on each of these dates. 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 dates.

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 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. A reconciliation of those components is presented below (in millions):

Note 7 -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, 2023 and 2022 (in millions):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Income from continuing operations attributable to our shares	$	12.9	$	74.3	$	30.2	$	147.3
Weighted average shares outstanding:
Basic	73.7		75.1		74.6		75.0
Effect of stock equivalents	1.1		0.5		1.1		0.5
Diluted	74.8		75.6		75.7		75.5

Anti-dilutive share awards totaling 35,000 and 104,000 were excluded from the computation of diluted EPS for the three and nine months ended September 30, 2023, respectively.

Anti-dilutive share awards totaling 38,000 and 103,000 were excluded from the computation of diluted EPS for the three and nine months ended September 30, 2022, respectively.

We had 5,470,950 warrants outstanding (the "Warrants") as of September 30, 2023 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.

Note 8 -Debt

First Lien Notes

On April 3, 2023, the Company issued a notice of conditional redemption to the holders of the Senior Secured First Lien Notes due 2028 (the "First Lien Notes") at a redemption price equal to 104.0% of the aggregate $550.0 million principal amount of the First Lien Notes plus accrued and unpaid interest to, but not including, the redemption date (the “Redemption Price”). On April 19, 2023, in connection with the issuance of our Second Lien Notes, as discussed below, the Company discharged its obligations under the indenture governing the First Lien Notes and deposited the Redemption Price with Wilmington Savings Fund Society, as trustee under such indenture. The First Lien Notes were redeemed on May 3, 2023 for an aggregate redemption price of $571.8 million (excluding accrued and unpaid interest). We accounted for the redemption as an extinguishment of debt and reported a corresponding loss of $29.2 million in the second quarter of 2023, which is included in our Condensed Consolidated Statements of Operations for the nine months ended September 30, 2023.

Second Lien Notes

On April 19, 2023, the Company and Valaris Finance Company LLC (“Valaris Finance”), a wholly-owned subsidiary, issued and sold $700.0 million aggregate principal amount of Second Lien Notes (the "Initial Second Lien Notes") in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act of

17

1933, as amended (the “Securities Act”). The Initial Second Lien Notes were issued at par for net proceeds of $681.4 million, after deducting the initial purchasers’ discount and offering expenses. A portion of the proceeds were used to fund the redemption of all of the outstanding First Lien Notes as discussed above.

On August 21, 2023, the Company and Valaris Finance issued $400.0 million aggregate principal amount of additional Second Lien Notes (the "Additional Notes") in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act. The Additional Notes were issued at 100.75% of par, plus accrued interest from April 19, 2023. The net proceeds were approximately $396.9 million after deducting the initial purchasers’ discount and estimated offering expenses, and excluding accrued interest received of $11.4 million.

The Initial Second Lien Notes and the Additional Notes were issued under the Indenture, dated as of April 19, 2023 (the "Indenture"), and mature on April 30, 2030. The Second Lien Notes bear an interest rate of 8.375% per annum with an effective interest rate of 8.76%. Interest is payable semi-annually in arrears on April 30 and October 30 of each year, beginning on October 30, 2023. The Second Lien Notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by the Guarantors and by each of the Company’s future restricted subsidiaries (other than Valaris Finance) that guarantees any debt of the Issuers or any guarantor under certain future debt in an aggregate principal amount in excess of a certain amount. The Second Lien Notes and the related guarantees are secured on a second-priority basis by the Collateral (as defined below).

On or after April 30, 2026, the Issuers may, at their option, redeem all or any portion of the Second Lien Notes, at once or over time, at the redemption prices set forth below, plus accrued and unpaid interest, if any, to, but not including, the redemption date. The following prices are for Second Lien Notes redeemed during the 12-month period commencing on April 30 of the years set forth below, and are expressed as percentages of principal amount:

Redemption Year	Price
2026	104.188%
2027	102.094%
2028 and thereafter	100.000%

At any time prior to April 30, 2026, the Issuers may, on any one or more occasions, redeem up to 40.0% of the aggregate principal amount of the Second Lien Notes issued under the Indenture (including any additional Second Lien Notes issued in the future) with an amount equal to or less than the net cash proceeds of certain equity offerings, at a redemption price equal to 108.375% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to but not including, the redemption date. In addition, at any time prior to April 30, 2026, the Issuers may redeem up to 10.0% of the aggregate principal amount of the Second Lien Notes during any twelve-month period at a redemption price equal to 103.0% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the redemption date.

At any time prior to April 30, 2026, the Issuers may redeem some or all of the Second Lien Notes at a price equal to 100.0% of the principal amount of the Second Lien Notes redeemed, plus accrued and unpaid interest, if any, to, but not including, the redemption date, plus a “make-whole” premium.

The Indenture contains covenants that, among other things, restrict the Company’s ability and the ability of certain of its subsidiaries to: (i) incur additional debt and issue certain preferred stock; (ii) incur or create liens; (iii) make certain distributions, investments and other restricted payments; (iv) sell or otherwise dispose of certain assets; (v) engage in certain transactions with affiliates; and (vi) merge, consolidate, amalgamate or sell, transfer, lease or otherwise dispose of all or substantially all of the Company’s assets. These covenants are subject to important exceptions and qualifications. In addition, many of these covenants will be suspended with respect to the Second Lien Notes during any time that the Second Lien Notes have investment grade ratings from at least two rating agencies and no default with respect to the Second Lien Notes has occurred and is continuing. As of September 30, 2023, we were in compliance with our covenants under the Indenture.

18

Upon the occurrence of certain Change of Control Triggering Event (as defined in the Indenture), the Issuers may be required to make an offer to repurchase all of the Second Lien Notes then outstanding at a price equal to 101.0% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the repurchase date.

Senior Secured Revolving Credit Facility

On April 3, 2023, the Company entered into a senior secured revolving credit agreement (the “Credit Agreement”). The Credit Agreement provides for commitments permitting borrowings of up to $375.0 million (which may be increased, subject to the satisfaction of certain conditions and the agreement of lenders to provide such additional commitments, by an additional $200.0 million pursuant to the terms of the 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 (together with Valaris Finance, the “Guarantors”) guarantee the Company’s obligations under the Credit Agreement, and the lenders have a first priority lien on the assets securing the Credit Agreement. The commitments under the Credit Agreement became available to be borrowed on April 19, 2023 (the "Availability Date").

The Credit Agreement and the related guarantees are secured on a first-priority basis, subject to permitted liens, by (a) first preferred ship mortgages over each vessel owned by us and the Guarantors as of the Availability Date, with certain exceptions (the “Collateral Vessels”); (b) first priority assignments of certain insurances and requisition compensation in respect of the Collateral Vessels; (c) first priority pledges of all equity interests in our subsidiaries that own Collateral Vessels and certain subsidiaries that hold equity interests in entities that own vessels (the “Collateral Rig Owners”); (d) first priority assignments of earnings of the Collateral Vessels from the Collateral Rig Owners; (e) any vessels and other assets of ours and the Guarantors that are pledged, at our option, to secure the Credit Agreement; and (f) all proceeds thereof (the "Collateral").

Amounts borrowed under the 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 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.

In addition to paying interest on outstanding borrowings under the Credit Agreement, we are required to pay a quarterly commitment fee to the lenders under the 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 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. We are also required to pay customary agency fees in respect of the Credit Agreement.

The Credit Agreement contains various covenants that limit, among other things, our and our restricted subsidiaries’ ability to: incur indebtedness; grant liens; dispose of certain assets; make certain acquisitions and investments; redeem or prepay other debt or make other restricted payments such as distributions to shareholders; enter into transactions with affiliates; enter into sale-leaseback transactions; and enter into a merger, amalgamation, consolidation or sale of assets. Further, the Credit Agreement contains financial covenants that require us to maintain (i) a minimum book value of equity to total assets ratio, (ii) a minimum interest coverage ratio and (iii) a minimum amount of liquidity.

Share Repurchase Program

In 2022, our board of directors authorized a share repurchase program under which we may purchase up to $100.0 million of our outstanding Common Shares. In April 2023, the board of directors authorized an increase of this amount to $300.0 million. The share repurchase program does not have a fixed expiration, may be modified, suspended or discontinued at any time and is subject to compliance with applicable covenants and restrictions under our financing agreements. During the three months ended September 30, 2023, we repurchased 1.2 million shares at an aggregate cost of $85.0 million at an average price of $73.30. During the nine months ended September 30, 2023, we repurchased 2.3 million shares at an aggregate cost of $150.0 million at an average price of $66.24.

Note 10 -Income Taxes

Historically, we calculated our provision for income taxes during interim reporting periods by applying the estimated annual effective tax rate for the full fiscal year to pre-tax income or loss, excluding discrete items, for the reporting period. We determined that since small changes in estimated pre-tax income or loss would result in significant changes in the estimated annual effective tax rate, the historical method would not provide a reliable estimate of income taxes for the three and nine months ended September 30, 2023 and 2022, and therefore, we used a discrete effective tax rate method to calculate income taxes for each of these periods. We will continue to evaluate income tax estimates under the historical method in subsequent quarters and employ a discrete effective tax rate method if warranted.

Discrete income tax benefit for the three months ended September 30, 2023 was $2.0 million and was primarily attributable to the resolution of prior period tax matters, partially offset by changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years. Discrete income tax benefit of $39.5 million for the nine months ended September 30, 2023 was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and the resolution of other prior period tax matters. Excluding the aforementioned discrete tax items, income tax expense for the three and nine months ended September 30, 2023 was $12.7 million and $47.1 million, respectively.

21

A substantial portion of our deferred tax assets are subject to a valuation allowance. During the three months ended September 30, 2023, we recognized a $6.2 million deferred tax benefit from the reduction of valuation allowances on deferred tax assets for a change in estimated future taxable income in certain operating jurisdictions. We intend to continue maintaining a valuation allowance on a substantial portion of our deferred tax assets until there is sufficient evidence to support a reversal of such allowances. However, given the current operating environment and our anticipated future earnings, we believe there is a reasonable possibility that sufficient positive evidence may become available to allow us to reach a conclusion that a portion of the valuation allowance on deferred tax assets will no longer be needed. A reduction in our valuation allowance would result in the recognition of a deferred tax benefit during the period in which the reduction is recognized. The timing and amount of future valuation allowance reductions are subject to future levels of contracting and profitability achieved.

Discrete income tax expense for the three months ended September 30, 2022 was $1.4 million and was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years, partially offset by discrete tax benefits attributable to the resolution of other prior period tax matters. Discrete income tax benefit for the nine months ended September 30, 2022 was $6.9 million and was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and resolution of other prior period tax matters, partially offset by discrete tax expense attributable to income associated with a contract termination. Excluding the aforementioned discrete tax items, income tax expense for the three and nine months ended September 30, 2022 was $12.4 million and $40.2 million, respectively.

Note 11 -Contingencies

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. ARO has plans to purchase 20 newbuild jackup rigs over an approximate 10-year period. The joint venture partners intend for the newbuild jackup rigs to be financed out of available cash from ARO's operations and/or funds available from third-party debt financing. In January 2020, ARO paid 25% of the purchase price from cash on hand for each of the two newbuilds, and in October 2023, entered into a $359.0 million term loan to finance the remaining payments due upon delivery and for general corporate purposes. The term loan matures in eight years following the related drawdown under the term loan and requires equal quarterly amortization payments during the term, with a 50% balloon payment due at maturity. The term loan bears interest based on the three-month Secured Overnight Financing Rate (SOFR) plus a margin ranging from 1.25% to 1.4%. Our Notes Receivable from ARO are subordinated and junior in right of payment to ARO’s term loan. In the event ARO has insufficient cash from operations 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 shall be reduced by the actual cost of each newbuild rig, as delivered, on a proportionate basis.

Letters of Credit

In the ordinary course of business with customers and others, we have entered into letters of credit 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 outstanding as of September 30, 2023 totaled $95.8 million and are issued under facilities provided by various banks and other financial institutions, but none were issued under the Credit Agreement. Obligations under these letters of credit are not normally called, as we typically comply with the underlying performance requirements. As of September 30, 2023, we had collateral deposits in the amount of $14.0 million with respect to these agreements.

22

Patent Litigation

In December 2022, a subsidiary of Transocean Ltd. commenced an arbitration proceeding against us alleging breach of a license agreement related to certain dual-activity drilling patents. We are unable to estimate our potential exposure, if any, to the proceeding at this time but do not believe that our ultimate liability, if any, resulting from this proceeding will have a material effect on our consolidated financial condition, results of operations or cash flows. We do not believe that we have breached the license agreement and intend to defend ourselves vigorously against this claim.

Brazil Administrative Proceeding

In July 2023, we received notice of an administrative proceeding initiated against us in Brazil. Specifically, the Federal Court of Accounts ("TCU") is seeking from us, Samsung Heavy Industries (“SHI”) and others, on a joint and several basis, a total of approximately BRL 601 million (approximately $120.0 million at the current quarter-end exchange rates) in damages that TCU asserts arose from the overbilling to Petrobras in 2015 in relation to the drilling services agreement with Petrobras for VALARIS DS-5 (the “DSA”). As fully disclosed in our prior periodic reports, the DSA was previously the subject of (1) investigations by the SEC and the U.S Department of Justice, each of which closed their investigation of us in 2018 without any enforcement action, (2) an arbitration proceeding against SHI in which we prevailed resulting in SHI making a $200.0 million cash payment to us in December 2019, and (3) a settlement with Petrobras normalizing our business relations in August 2018. We plan to vigorously defend ourselves against the allegations made by the TCU. Because these proceedings are in their initial stages, we are unable to estimate our potential exposure, if any, at this time.

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.

Note 12 -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 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 expense and Depreciation expense 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 deducted under "Reconciling Items" and replaced with our equity in earnings of ARO. See "Note 3 - Equity Method Investment in ARO" for additional information on ARO and related arrangements.

We received an income tax refund of $45.9 million during the first quarter of 2023 related to the U.S. Coronavirus Aid, Relief, and Economic Security Act.

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 or nine months ended September 30, 2023, and 2022 were as follows:

Item 2.  Management's Discussion and Analysis of Financial Condition and Results of Operations

Management's Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the accompanying unaudited condensed consolidated financial statements and related notes thereto included in "Item 1. Financial Statements" and with our annual report on Form 10-K for the year ended December 31, 2022. The following discussion and analysis contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under “Risk Factors” in Item 1A of our annual report and elsewhere in this quarterly report. See “Forward-Looking Statements.”

EXECUTIVE SUMMARY

Our Business

We are a leading provider of offshore contract drilling services to the international oil and gas industry with operations in almost every major offshore market across six continents. We own the world's largest offshore drilling rig fleet, including one of the newest ultra-deepwater fleets in the industry and a leading premium jackup fleet. We currently own 51 rigs, including 11 drillships, four dynamically positioned semisubmersible rigs, one moored semisubmersible rig, 35 jackup rigs and a 50% equity interest in ARO, our 50/50 unconsolidated joint venture with Saudi Aramco, which owns an additional seven rigs. We also have options to purchase two recently constructed drillships, which we plan to exercise on or before December 31, 2023.

Our Industry

Operating results in the offshore contract drilling industry are highly cyclical and are directly related to the demand for and the available supply of drilling rigs. Low demand and excess supply can independently affect day rates and utilization of drilling rigs. Therefore, adverse changes in either of these factors can result in adverse changes in our industry. While the cost of moving a rig may cause the balance of supply and demand to vary somewhat between regions, significant variations between most regions are generally of a short-term nature due to rig mobility.

In the first nine months of 2023, we have seen relatively less volatility in oil prices than that experienced in 2022 and prices have generally remained at levels that are supportive of offshore exploration and development activity. At the start of 2023, the Brent crude price was in the low-80's per barrel. The price declined somewhat during the first quarter of 2023, following turmoil in the banking sector, which escalated fears of a global recession and declining oil demand. However, the price per barrel has since rebounded in part due to OPEC+ announcing a further production cut of approximately 1.2 million barrels per day effective from May 2023 through the end of the year. In early September, the Brent crude price climbed above $90 per barrel for the first time since November 2022, where it has largely remained, primarily due to Saudi Arabia and Russia announcing that they would extend additional voluntary production cuts through year-end and an escalation in geopolitical risk in the Middle East.

Despite the volatility in spot oil prices seen in recent years, our customers tend to be more focused on medium-term and long-term commodity prices when making investment decisions due to the longer lead times for offshore projects. These forward prices experienced far less volatility in 2022 and thus far in 2023 and have maintained levels which are highly constructive for offshore project demand.

Rig attrition in the industry over the last several years, particularly for floaters, has resulted in a much smaller global fleet of rigs that is available to meet customer demands. Consequently, our outlook for our offshore drilling business is positive.

29

Inflationary pressures remain elevated and have resulted in increased personnel costs as well as in the prices of goods and services required to operate our rigs or execute capital projects. We expect that our costs will continue to rise in the near term and although certain of our long-term contracts contain provisions for escalating costs, we cannot predict with certainty our ability to successfully claim recoveries of higher costs from our customers under these contractual stipulations. Despite the inflationary trends and macroeconomic uncertainty, recovery in demand for offshore drilling services continues to improve as evidenced by increasing global utilization and day rates for offshore drilling rigs.

Backlog

Our contract drilling backlog reflects commitments, represented by signed drilling contracts, and is calculated by multiplying the contracted operating day rate by the contract period. The contracted day rate excludes certain types of lump sum fees for rig mobilization, demobilization, contract preparation, as well as customer reimbursables and bonus opportunities. Our backlog excludes ARO's backlog, but includes backlog from our rigs leased to ARO at the contractual rates, which are subject to adjustment under the terms of the shareholder agreement governing the joint venture.

ARO backlog presented is 100% of their backlog and is inclusive of backlog on both ARO owned rigs and rigs leased from us. As an unconsolidated 50/50 joint venture, when ARO realizes revenue from its backlog, 50% of the earnings thereon would be reflected in our results in equity in earnings (losses) of ARO in our Condensed Consolidated Statement of Operations. The earnings from ARO backlog with respect to rigs leased from us will be net of, among other things, payments to us under bareboat charters for those rigs. See "Note 3 - Equity Method Investment in ARO" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information.

The following table summarizes our and ARO's contract backlog of business as of November 1, 2023 and February 21, 2023 (in millions):

	November 1, 2023		February 21, 2023
Floaters (1)	$	1,986.0	$	1,376.9
Jackups(2)	921.6		742.3
Other (3)	250.5		344.0
Total	$	3,158.1	$	2,463.2
ARO (4)	$	2,290.7	$	1,731.8

(1)The increase in Floaters is primarily due to a three-year contract for VALARIS DS-8 offshore Brazil, a 12-well contract for VALARIS DS-7 offshore West Africa and a 250-day contract extension for VALARIS DS-15 offshore Brazil, which resulted in incremental aggregate backlog of approximately $890.0 million. These increases were partially offset by revenues realized.

(2)The increase in Jackups is primarily due to contract awards and extensions for VALARIS 107, VALARIS 72, VALARIS 118, VALARIS 92 and VALARIS 106, which resulted in incremental aggregate backlog of approximately $340.0 million. These increases were partially offset by revenues realized.

(3)Other includes the bareboat charter backlog for the jackup rigs leased to ARO to fulfill contracts between ARO and Saudi Aramco in addition to backlog for our managed rig services. Substantially all the operating costs for jackups leased to ARO through the bareboat charter agreements will be borne by ARO.

(4)The increase in ARO backlog is primarily due to an eight-year contract for each of the two newbuild rigs, the first of which was delivered in October 2023 and the second is expected to be delivered in the first quarter of 2024. These contracts resulted in incremental aggregate backlog of approximately $924.0 million, which was partially offset by revenues realized.

BUSINESS ENVIRONMENT

Floaters

In recent years, the more constructive oil price environment has led to an improvement in contracting and tendering activity for floaters. The number of contracted benign environment floaters has increased to 120 at September 30, 2023 from a low of 101 in early 2021, contributing to a 13% increase in global utilization, from 73% to 86%, for the industry's active fleet over the same period. This increase in activity is particularly evident for 6th and 7th generation drillships, such as those included in our floater fleet. Utilization for the global active 6th and 7th generation drillship fleet is currently at 94% and has, on average, exceeded 90% for more than twelve months, resulting in a meaningful improvement in day rates for this class of assets.

In 2022, we completed the reactivation of three drillships and one semisubmersible which have commenced long-term contracts. In 2023, we have completed the reactivation of another stacked drillship, VALARIS DS-17, for a contract which commenced in the third quarter of 2023 for work offshore Brazil, and we are currently reactivating another two of our stacked drillships, VALARIS DS-7 and DS-8, for long-term contracts offshore West Africa and Brazil, respectively.

From a supply perspective, as of September 30, 2023, the number of benign environment floaters including stacked rigs declined by 43% to 159 from a peak of 281 in late 2014, and we believe there are only ten competitive drillships remaining among the stacked drillship fleet, including VALARIS DS-11. There are a further eight competitive newbuild drillships remaining at South Korean shipyards, including VALARIS DS-13 and DS-14, for which, based on current market conditions, we expect to exercise our options to take delivery by the end of 2023. However, three of these eight rigs are either contracted or have been selected for future work and are expected to be contracted soon. We expect that continued floater demand growth will further reduce available drillship capacity. Also, given the expected high construction cost and lack of shipyard capacity, we do not believe that current market conditions are supportive of another newbuild cycle in the foreseeable future.

Jackups

Contracting and tendering activity for jackups has begun to improve in recent years as a result of the more constructive oil price environment. Further, we have seen a notable increase in jackup activity since the beginning of 2022, primarily driven by demand from the Middle East. The number of contracted jackups has increased to 404 at September 30, 2023 from a low of 341 in early 2021, contributing to a 15% increase in global utilization, from 78% to 93%, for the industry's active fleet over the same period, which has led to a meaningful increase in day rates for jackups.

As of September 30, 2023, the number of jackups declined by 8% to 496 from a peak of 542 in early 2015. While the number of jackups has decreased less than floaters on a relative basis, 33% of the current jackup fleet is more than 30 years of age with limited useful lives remaining. Further, we believe that some of the jackups that are currently idle are not competitive, either due to their age or length of time stacked. Expenditures required to recertify some of these rigs may prove cost prohibitive and drilling contractors may instead elect to scrap a portion of these rigs. Excluding ARO's newbuild program, there are only 18 newbuild jackups remaining at shipyards, of which 13 are at Chinese shipyards, many of which are expected to be used for the local supply in China.

RESULTS OF OPERATIONS

Management believes the comparison of the most recently completed quarter to the immediately preceding quarter provides more relevant information needed to understand and analyze the business. As such, as permitted under applicable SEC rules, we have elected to discuss any material changes in our results of operations by including a comparison of our most recently completed fiscal quarter ended September 30, 2023 (the "current quarter") to the immediately preceding fiscal quarter ended June 30, 2023 (the "preceding quarter"). We also continue to discuss any material changes in our results of operations for the nine months ended September 30, 2023 compared to the corresponding period of the preceding fiscal year (the "prior year period"), as required under the applicable SEC rules.

Three Months Ended September 30, 2023 Compared to Three Months Ended June 30, 2023

The following table summarizes our Condensed Consolidated Results of Operations for the three months ended September 30, 2023 and June 30, 2023 (in millions, except percentages):

	Three Months Ended				Change		% Change
	September 30, 2023		June 30, 2023
Revenues	$	455.1	$	415.2	$	39.9	10	%
Operating expenses
Contract drilling (exclusive of depreciation)	390.9		373.5		17.4		5	%
Depreciation	25.8		24.5		1.3		5	%
General and administrative	24.2		26.4		(2.2)		(8)	%
Total operating expenses	440.9		424.4		16.5		4	%
Equity in earnings (losses) of ARO	2.4		(0.7)		3.1		(443)	%
Operating income (loss)	16.6		(9.9)		26.5		(268)	%
Other income, net	11.1		7.1		4.0		56	%
Provision for income taxes	10.7		24.5		(13.8)		(56)	%
Net income (loss)	17.0		(27.3)		44.3		(162)	%
Net income attributable to noncontrolling interests	(4.1)		(2.1)		(2.0)		95	%
Net income (loss) attributable to Valaris	$	12.9	$	(29.4)	$	42.3	(144)	%

Revenue increased primarily due to $34.0 million of incremental revenue earned for VALARIS DS-17, VALARIS 249 and VALARIS 121, which commenced new contracts in the current quarter after not working in the preceding quarter. Excluding these rigs, revenue increased $5.9 million which was primarily due to $19.8 million from higher average daily revenue earned, partially offset by a $17.3 million decrease in operating days primarily related to downtime for contract preparation and mobilization of rigs and unplanned downtime during the current quarter.

Contract drilling expense increased primarily due to $13.3 million of higher costs attributable to rigs that were idle in the prior quarter and commenced new contracts during the current quarter and a $6.9 million increase in rig reactivation costs.

Other income, net, increased primarily due to a $29.2 million loss recognized in the preceding quarter on the extinguishment of the Senior Secured First Lien Notes (the "First Lien Notes") and a $4.3 million increase in foreign currency gains. These increases were partially offset by a $27.3 million pre-tax gain recognized in the preceding quarter for the sale of VALARIS 54.

32

Discrete income tax benefit for the current quarter was $2.0 million and was primarily attributable to the resolution of prior period tax matters, partially offset by changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years. Discrete income tax expense for the preceding quarter was $6.2 million and was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years. Excluding the aforementioned discrete tax items, income tax expense decreased to $12.7 million for the current quarter from $18.3 million for the preceding quarter, primarily due to a deferred tax benefit of $6.2 million recognized in the current quarter from the reduction of valuation allowances on deferred tax assets for a change in estimated future taxable income in certain operating jurisdictions.

Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022

The following table summarizes our Condensed Consolidated Results of Operations for the nine months ended September 30, 2023 and 2022 (in millions, except percentages):

	Nine Months Ended				Change		% Change
	September 30, 2023		September 30, 2022
Revenues	$	1,300.4	$	1,168.9	$	131.5	11	%
Operating expenses
Contract drilling (exclusive of depreciation)	1,141.6		1,029.8		111.8		11	%
Loss on impairment	—		34.5		(34.5)		(100)	%
Depreciation	73.6		67.4		6.2		9	%
General and administrative	75.0		57.0		18.0		32	%
Total operating expenses	1,290.2		1,188.7		101.5		9	%
Equity in earnings of ARO	5.0		15.9		(10.9)		(69)	%
Operating income (loss)	15.2		(3.9)		19.1		(490)	%
Other income, net	30.7		187.9		(157.2)		(84)	%
Provision for income taxes	7.6		33.3		(25.7)		(77)	%
Net income	38.3		150.7		(112.4)		(75)	%
Net income attributable to noncontrolling interests	(8.1)		(3.4)		(4.7)		138	%
Net income attributable to Valaris	$	30.2	$	147.3	$	(117.1)	(79)	%

Revenues increased primarily due an increase in average daily revenue earned of $114.1 million primarily due to certain rigs that commenced new contracts during the nine months ended September 30, 2023 at a higher day rate, $68.2 million from an increase in operating days primarily attributable to rigs that have commenced contracts following reactivation, and $12.1 million of higher revenues earned from lease agreements with ARO primarily from higher lease rates for certain rigs. These increases were partially offset by a $51.0 million fee related to the termination of the VALARIS DS-11 contract recognized in the prior year period, and a $7.0 million decrease in customer reimbursable revenue.

Contract drilling expense increased primarily due to $104.7 million attributable to rigs that have commenced contracts following reactivation, a $31.2 million increase in repair costs for certain rigs, and a $17.4 million increase in reactivation costs. These increases were partially offset by a $28.5 million decrease in the costs for certain claims and a $14.8 million decrease in operating costs for VALARIS 140 and VALARIS 141, which we started leasing to ARO at the end of the first quarter and the third quarter of 2022, respectively.

During the nine months ended September 30, 2022, we recorded non-cash losses on impairment totaling $34.5 million, with respect to customer-specific capital upgrades for VALARIS DS-11 made pursuant to the terms of the drilling contract that was terminated during the second quarter of 2022. See "Note 5 - Property and Equipment" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information.

33

Depreciation expense increased primarily due to $7.7 million attributable to new assets placed in service for certain rigs that underwent reactivation projects and capital upgrades.

General and administrative expenses increased primarily due to higher compensation related to our long-term incentive plans and higher professional fees.

Other income, net, decreased primarily due to a $109.8 million decrease in the gain on the sale of assets, a $29.2 million loss on the extinguishment of our First Lien Notes recognized in the second quarter of 2023, a $21.8 million decrease in foreign currency gains, and a $12.4 million increase in interest expense, partially offset by a $24.2 million increase in interest income.

Discrete income tax benefit for the nine months ended September 30, 2023 was $39.5 million and was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and the resolution of other prior period tax matters Discrete income tax benefit for the nine months ended September 30, 2022 was $6.9 million and was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and resolution of other prior period tax matters, partially offset by discrete tax expense attributable to income associated with a contract termination. Excluding the aforementioned discrete tax items, income tax expense for the nine months ended September 30, 2023 and 2022 was $47.1 million and $40.2 million, respectively.

Rig Counts, Utilization and Average Daily Revenue

The following table summarizes the total and active offshore drilling rigs for Valaris and ARO as of the following dates:

	September 30, 2023	June 30, 2023	September 30, 2022
Total Fleet
Floaters	16	16	16
Jackups(1)	27	27	28

Jackups(6)	20	20	22
Other(2)	8	8	8
Active Fleet - Valaris	41	40	41
ARO(3)	7	7	7

(1)During the second quarter of 2023, we sold VALARIS 54.

(2)This represents the jackup rigs leased to ARO through bareboat charter agreements whereby substantially all operating costs are incurred by ARO. Rigs leased to ARO operate under long-term contracts with Saudi Aramco.

(3)This represents the seven jackup rigs owned by ARO which are operating under long-term contracts with Saudi Aramco.

(4)Active fleet represents rigs that are not preservation stacked and includes rigs that are in the process of being reactivated.

34

(5)During the first and third quarter of 2023, we began reactivating VALARIS DS-8 for a three-year contract offshore Brazil and VALARIS DS-7 for a 12-well contract offshore West Africa, respectively.

(6)During the first quarter of 2023, we preservation stacked VALARIS Viking after the rig completed its contract in the North Sea. During the second quarter of 2023, we sold VALARIS 54.

We provide management services in the U.S. Gulf of Mexico on two rigs owned by a third-party that are not included in the table above.

We are a party to contracts whereby we have the option to take delivery of VALARIS DS-13 and VALARIS DS-14, two recently constructed drillships that are not included in the table above.

Additionally, ARO has ordered two jackups which are under construction in the Middle East that are not included in the table above.

35

Operating results for our contract drilling services segment are largely dependent on two primary revenue metrics: utilization and day rates. The following table summarizes our and ARO's rig utilization and average daily revenue by reportable segment:

	Three Months Ended						Nine Months Ended
	September 30, 2023			June 30, 2023			September 30, 2023			September 30, 2022
Rig Utilization - Total Fleet(1)
Floaters	57		%	59		%	58		%	39		%
Jackups	58		%	55		%	58		%	65		%
Other (2)	100		%	100		%	100		%	100		%
Total Valaris	65		%	65		%	66		%	64		%
ARO	93		%	91		%	92		%	92		%
Rig Utilization - Active Fleet(1)
Floaters	70		%	78		%	76		%	60		%
Jackups	78		%	74		%	78		%	86		%
Other (2)	100		%	100		%	100		%	100		%
Total Valaris	81		%	82		%	83		%	83		%
ARO	93		%	91		%	92		%	92		%
Average Daily Revenue(3)
Floaters	$	278,821		$	252,417		$	258,780		$	229,381
Jackups	108,152			99,112			103,884			100,050
Other (2)	43,519			41,072			42,705			39,332
Total Valaris	$	134,124		$	124,184		$	127,272		$	106,610
ARO	$	94,712		$	94,624		$	95,837		$	93,834

(1)Rig utilization total fleet and active fleet are derived by dividing the operating days by the number of days in the period for the total fleet and active fleet, respectively. Active fleet represents rigs that are not preservation stacked and includes rigs that are in the process of being reactivated. Operating days equals the total number of days that rigs have earned and recognized day rate revenue, including days associated with early contract terminations, compensated downtime and mobilizations and excluding suspension periods. When revenue is deferred and amortized over a future period, for example, when we receive fees while mobilizing to commence a new contract or while being upgraded in a shipyard, the related days are excluded from operating days.

(2)Includes our two management services contracts and our rigs leased to ARO under bareboat charter contracts.

(3)Average daily revenue is derived by dividing contract drilling revenues, adjusted to exclude certain types of non-recurring reimbursable revenues, revenues earned during suspension periods and revenues attributable to amortization of drilling contract intangibles, by the aggregate number of operating days. Beginning with the current quarter, we began presenting average daily revenue instead of the previously reported average day rate metric, which further excluded lump-sum revenues and amortization thereof. Average daily revenue is a more comprehensive measurement of our revenue-earning performance and more closely aligns with the calculation methodology used by our closest offshore drilling peers. Prior periods were adjusted to conform with the current period presentation.

36

Operating Income by Segment

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 bareboat charter arrangements (the "Lease Agreements"). Floaters, Jackups and ARO are also reportable segments.

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 expense and depreciation expense 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."

The full operating results included below for ARO are not included within our consolidated results and thus deducted under "Reconciling Items" and replaced with our equity in earnings (losses) of ARO. See "Note 3 - Equity Method Investment in ARO" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information.

Floaters

Floater revenue increased $15.9 million for the current quarter as compared to the preceding quarter, primarily due to $13.1 million from VALARIS DS-17, which commenced a new contract in Brazil in the current quarter following reactivation. Revenue for the remaining floater fleet increased due to $14.8 million from higher average daily revenue earned by certain rigs, partially offset by an $11.3 million decrease in operating days, primarily due to unplanned downtime for certain rigs and the mobilization of VALARIS DPS-5 to a new contract in the current quarter.

Floater contract drilling expense increased $19.0 million for the current quarter as compared to the preceding quarter, primarily due to an $16.6 million increase in rig reactivation costs for VALARIS DS-7, which commenced a reactivation project in the current quarter in preparation of a new contract in West Africa.

Jackups

Jackup revenues increased $21.3 million for the current quarter as compared to the preceding quarter, primarily due to $20.9 million from VALARIS 249 and VALARIS 121, which commenced new contracts during the current quarter after being idle in the preceding quarter.

ARO

The operating revenues of ARO reflect revenues earned under drilling contracts with Saudi Aramco for both the ARO-owned jackup rigs and the rigs leased from us. Contract drilling expenses are inclusive of the bareboat charter fees for the rigs leased from us. See "Note 3 - Equity Method Investment in ARO" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information on ARO.

ARO revenue increased $3.7 million for the current quarter as compared to the preceding quarter, primarily due to $3.5 million of higher revenue for certain rigs which were undergoing maintenance projects during the preceding quarter.

ARO contract drilling expense decreased $3.0 million for the current quarter as compared to the preceding quarter, primarily due to a $5.0 million decrease in repair and maintenance cost in the current quarter, partially offset by a $2.3 million increase in lease expense.

Other

Other revenue increased $2.7 million for the current quarter as compared to the preceding quarter, primarily due to $2.3 million of higher revenues earned from lease agreements with ARO.

Floaters

Floater revenue increased $196.0 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to $204.2 million from increased operating days primarily attributable to rigs that have commenced contracts following reactivation or returned to work upon completion of special periodic surveys and $58.7 million from higher average daily revenue earned primarily due to VALARIS DS-12 and VALARIS DPS-5 working under higher day rate contracts in the current period as compared to the prior year period. These increases were partially offset by $51.0 million of revenue recognized in the prior year period attributable to a termination fee for the VALARIS DS-11 contract and an $11.7 million decrease from customer reimbursable revenue.

Floater contract drilling expense increased $112.6 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to $129.9 million attributable to rigs that have returned to work upon completion of reactivation projects and an $18.4 million increase in reactivation costs. These increases were partially offset by a $21.3 million decrease in the costs for certain claims and an $11.8 million decrease in reimbursable costs.

During the prior year period, we recorded non-cash losses on impairment totaling $34.5 million, with respect to customer-specific capital upgrades for VALARIS DS-11 made pursuant to the terms of the drilling contract that was terminated during the second quarter of 2022.

39

Floater depreciation expense increased $3.7 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to new assets placed in service for certain rigs that underwent reactivation projects and capital upgrades.

Jackups

Jackup revenues decreased $82.1 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to $136.0 million from decreased operating days primarily due to rigs that completed contracts in the North Sea during the first half of 2023, certain rigs that were mobilizing or are idle between contracts in the current period, and the sale of VALARIS 54 which operated in the prior year period. These decreases were partially offset by a $52.2 million increase due to higher average daily revenue earned.

Jackup contract drilling expense decreased $15.3 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to $33.1 million lower costs for rigs that were idle or between contracts in the current period, and a $14.8 million decrease in operating costs for VALARIS 140 and VALARIS 141, which we started leasing to ARO at the end of the first quarter and the third quarter of 2022, respectively. These decreases were partially offset by a $30.5 million increase in repair costs in the current period primarily associated with maintenance performed during special period surveys.

ARO

ARO revenue increased $23.8 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to $21.6 million from VALARIS 140 and VALARIS 141, which ARO started leasing from us at the end of the first quarter and the third quarter of 2022, respectively, and $17.9 million from higher average daily revenue earned by certain rigs. These increases were partially offset by a $9.0 million decrease due to VALARIS 36 which operated in the prior year period until the rig was sold in May 2022 and $8.1 million for certain rigs undergoing maintenance projects in the current period.

ARO contract drilling expense increased $21.6 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to $9.0 million from higher personnel cost, $8.6 million of incremental operating costs primarily related to VALARIS 140 and VALARIS 141, and a $6.3 million increase in repair and maintenance.

Other

Other revenue increased $17.6 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to $12.1 million of higher revenues earned from lease agreements with ARO from higher average day rates on certain rigs, $3.2 million from higher day rates on certain rigs and $2.3 million increase in customer reimbursable revenues.

Three Months Ended September 30, 2023 Compared to Three Months Ended June 30, 2023

During the preceding quarter, we recognized a loss of $29.2 million on the extinguishment of the First Lien Notes and a $27.3 million gain on the sale of property from the sale of VALARIS 54.

Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022

Interest income increased by $24.2 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to an increase of $26.8 million of interest income on cash equivalents due to a higher average balance during the current period and a $14.2 million increase on interest income earned on our Notes Receivable from ARO attributable to higher interest rates in 2023, partially offset by non-cash interest income of $14.8 million recognized in the prior year for the discount attributable to the partial principal repayment on our Notes Receivable from ARO in September 2022.

Interest expense increased by $12.4 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to an increase in interest expense from a higher principal debt balance.

Net foreign currency exchange gains of $3.4 million for the nine months ended September 30, 2023 primarily included gains of $3.1 million, $2.2 million and $0.9 million related to Nigerian naira, Norwegian kroner, and euros, respectively, partially offset by losses of $1.6 million each, from Brazilian reals and Angolan kwanza. Net foreign currency exchange gains of $25.2 million for the nine months ended September 30, 2022, primarily included gains of $14.4 million, $3.9 million and $3.6 million related to euros, British pounds and Norwegian kroner, respectively.

We recognized a $29.2 million loss from the extinguishment of the First Lien Notes for the nine months ended September 30, 2023.

Net gains on the sale of property decreased by $109.8 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to $135.5 million of gains recognized in the prior year period for the sales of VALARIS 113, VALARIS 114 and VALARIS 36 and additional proceeds received for the sale of a rig in a prior year as a result of post-sale conditions of that sale agreement. This decrease was partially offset by $27.3 million of pre-tax gains recognized during the nine months ended September 30, 2023 for the sale of the VALARIS 54.

41

Net periodic pension and retiree medical income decreased by $11.8 million for the nine months ended September 30, 2023 compared to the prior year period, primarily due to higher interest cost attributed to the increase in discount rate.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity

We expect to fund our short-term liquidity needs, including contractual obligations and anticipated capital expenditures, as well as working capital requirements, from cash and cash equivalents, cash flows from operations and borrowings under the Credit Agreement (as defined below). We expect to fund our long-term liquidity needs, including contractual obligations and anticipated capital expenditures from cash and cash equivalents, cash flows from operations, as well as cash to be received from maturity of our Notes Receivable from ARO and from the distribution of earnings from ARO. We may rely on the issuance of debt and/or equity securities in the future to supplement our liquidity needs. However, the Indenture, dated as of April 19, 2023 (the "Indenture"), and the Credit Agreement contain covenants that limit our ability to incur additional indebtedness.

Our cash and cash equivalents as of September 30, 2023 and December 31, 2022 were $1.0 billion and $724.1 million, respectively. We have no debt principal payments due until 2030 and had $375.0 million available for borrowings, including up to $150.0 million for the issuance of letters of credit, under the Credit Agreement as of November 2 , 2023. See below and "Note 8 - Debt" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information on the 8.375% Second Lien Notes due 2030 (the "Second Lien Notes").

Financing

First Lien Notes

On April 3, 2023, we issued a notice of conditional redemption to the holders of our Senior Secured First Lien Notes due 2028 (the “First Lien Notes”) at a redemption price equal to 104.0% of the principal amount of the First Lien Notes, plus accrued and unpaid interest to, but not including, the redemption date (the “Redemption Price”). On April 19, 2023, in connection with the issuance of our Second Lien Notes as discussed below, we discharged our obligations under the indenture that governed the First Lien Notes and deposited the Redemption Price with Wilmington Savings Fund Society, as trustee under such indenture. The First Lien Notes were redeemed on May 3, 2023 for an aggregate redemption price of approximately $571.8 million (excluding accrued and unpaid interest). See "Note 8 - Debt" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information on the First Lien Notes.

Second Lien Notes

On April 19, 2023, the Company and Valaris Finance Company LLC ("Valaris Finance," together, the "Issuers") issued and sold $700.0 million in aggregate principal amount of Secured Second Lien Notes (the “Initial Second Lien Notes”) in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). The Initial Second Lien Notes were issued at par for net proceeds of $681.4 million, after deducting the initial purchasers’ discount and offering expenses. A portion of the proceeds were used to fund the redemption of all of the outstanding First Lien Notes as discussed above.

Additionally, on August 21, 2023, the Issuers issued $400.0 million aggregate principal amount of additional Second Lien Notes (the "Additional Notes") in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act. The Additional Notes were issued at 100.75% of par, plus accrued interest from April 19, 2023, for net proceeds of approximately $396.9 million after deducting the initial purchasers’ discount and estimated offering expenses, and excluding accrued interest received of $11.4 million. We intend to

42

use a portion of the proceeds to finance the purchase of VALARIS DS-13 and VALARIS DS-14 as described in the capital expenditures discussion below.

The Initial Second Lien Notes and the Additional Notes were issued under the Indenture and form a single series. The Second Lien Notes mature on April 30, 2030 and bear an interest rate of 8.375% per annum. See "Note 8 - Debt" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information on the Second Lien Notes.

Senior Secured Revolving Credit Agreement

On April 3, 2023, we entered into a senior secured revolving credit agreement (the “Credit Agreement”). The Credit Agreement provides for commitments permitting borrowings of up to $375.0 million (which may be increased, subject to the satisfaction of certain conditions and the agreement of lenders to provide such additional commitments, by an additional $200.0 million pursuant to the terms of the Credit Agreement) and includes a $150.0 million sublimit for the issuance of letters of credit. Valaris Finance and certain other of our subsidiaries (together with Valaris Finance, the “Guarantors”) guarantee our obligations under the Credit Agreement, and the lenders have a first priority lien on the assets securing the Credit Agreement. The commitments under the Credit Agreement became available to be borrowed on April 19, 2023. See "Note 8 - Debt" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information on the Credit Agreement.

Cash Flows and Capital Expenditures

Absent periods where we have significant financing or investing transactions or activities, such as debt or equity issuances, debt repayments, business combinations or asset sales, our primary sources and uses of cash are driven by cash generated from or used in operations and capital expenditures. Our net cash provided by or used in operating activities and capital expenditures were as follows (in millions):

	Nine Months Ended September 30,
	2023		2022
Net cash provided by (used in) operating activities	$	170.8	$	(27.7)
Capital expenditures	$	(233.1)	$	(153.1)

During the nine months ended September 30, 2023, we generated $170.8 million from operating activities related primarily to higher margins, the collection of $45.9 million for certain tax receivables and other changes in working capital. Our primary uses of cash were $233.1 million for the enhancement and other improvements of our drilling rigs, including reactivations.

During the nine months ended September 30, 2022, our uses of cash in operating activities of $27.7 million related primarily to the reactivation of drilling rigs for new contracts as well as the payment of certain taxes.

We have construction agreements, as amended, with a shipyard that provide for, among other things, an option construct whereby we have the right, but not the obligation, to take delivery on or before December 31, 2023 of either or both VALARIS DS-13 and VALARIS DS-14. Under the amended agreements, the purchase prices for the rigs are estimated to be $119.1 million for VALARIS DS-13 and $218.3 million for VALARIS DS-14, assuming a December 31, 2023 delivery date. If we elect not to purchase the rigs, we have no further obligations to the shipyard. Based on current market conditions, we expect to exercise our options to purchase and take delivery of the rigs by the end of 2023 and intend to fund the purchase prices with cash on hand.

43

We continue to take a disciplined approach to reactivations with our stacked rigs, only returning them to the active fleet for opportunities that provide meaningful returns. Most of the reactivation cost will be operating expenses, recognized in the income statement, related to de-preservation activities, including reinstalling key pieces of equipment and crew costs. Capital expenditures during reactivations include rig modifications, equipment overhauls and any customer required capital upgrades. We would generally expect to be compensated for any customer-specific enhancements.

The costs of future reactivations are expected to increase relative to our initial reactivation projects with rising costs of labor and materials, the depletion of spares from our initial reactivation projects and as the rigs we reactivate have been preservation stacked for longer periods of time. Future reactivations could be subject to further increases in the cost of labor and materials and could take longer due to increased lead times for parts and supplies.

Based on our current projections, we expect capital expenditures during 2023 to be approximately $340 million, exclusive of costs to exercise our options to take delivery of VALARIS DS-13 and VALARIS DS-14. Exercising our options to take delivery of VALARIS DS-13 for $119.1 million and VALARIS DS-14 for $218.3 million assuming a December 31, 2023 delivery date, will increase our projected capital expenditures by the respective purchase prices. Depending on market conditions, contracting activity and future opportunities, we may reactivate additional rigs or make additional capital expenditures to upgrade rigs for customer requirements and construct or acquire additional rigs.

We review from time to time possible acquisition opportunities relating to our business, which may include the acquisition of rigs or other businesses. The timing, size or success of any acquisition efforts and the associated potential capital commitments are unpredictable and uncertain. We may seek to fund all or part of any such efforts with cash on hand and proceeds from debt and/or equity issuances and may issue equity directly to the sellers. Our ability to obtain capital for additional projects to implement our growth strategy over the longer term will depend on our future operating performance, restrictions to incur additional debt in the Indenture and the Credit Agreement, financial condition and, more broadly, on the availability of equity and debt financing. Capital availability will be affected by prevailing conditions in our industry, the global economy, the global financial markets and other factors, many of which are beyond our control. In addition, any additional debt service requirements we take on could be based on higher interest rates and shorter maturities and could impose a significant burden on our results of operations and financial condition, and the issuance of additional equity securities could result in significant dilution to shareholders.

Capital Resources

Investment in ARO and Notes Receivable from ARO

We consider our investment in ARO to be a significant component of our investment portfolio and an integral part of our long-term capital resources. We expect to receive cash from ARO in the future both from the maturity of our Notes Receivable from ARO and from the distribution of earnings from ARO.

The Notes Receivable from ARO, which are governed by the laws of Saudi Arabia, mature during 2027 and 2028. In the event that ARO is unable to repay the Notes Receivable from ARO when they become due, we would require the prior consent of our joint venture partner to enforce ARO’s payment obligations.

The following table summarizes the maturity schedule of our Notes Receivable from ARO as of September 30, 2023 (in millions):

Maturity Date	Principal Amount
October 2027	$	225.0
October 2028	177.7
Total	$	402.7

44

The distribution of earnings to the joint-venture partners is at the discretion of the ARO board of managers, consisting of 50/50 membership of managers appointed by Saudi Aramco and managers appointed by us, with approval required by both shareholders. The timing and amount of any cash distributions to the joint venture partners cannot be predicted with certainty and will be influenced by various factors, including the liquidity position and long-term capital requirements of ARO. ARO has not made a cash distribution of earnings to its partners since its formation.

See "Note 3 - Equity Method Investment in ARO" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information on our investment in ARO and Notes Receivable from ARO.

Share Repurchase Program

In 2022, our board of directors authorized a share repurchase program under which we may purchase up to $100.0 million of our outstanding Common Shares. In April 2023, the board of directors authorized an increase of this amount to $300.0 million. The share repurchase program does not have a fixed expiration, may be modified, suspended or discontinued at any time and is subject to compliance with applicable covenants and restrictions under our financing agreements. During the three months ended September 30, 2023, we repurchased 1.2 million shares at an aggregate cost of $85.0 million at an average price of $73.30. During the nine months ended September 30, 2023, we repurchased 2.3 million shares at an aggregate cost of $150.0 million at an average price of $66.24. Including repurchases made during the nine months ended September 30, 2023, we expect to repurchase shares for an approximate aggregate cost of $200.0 million by the end of 2023.

Other Commitments

We have other commitments that we are contractually obligated to fulfill with cash under certain circumstances. As of September 30, 2023, we were contingently liable for an aggregate amount of $95.8 million under outstanding letters of credit which guarantee our performance as it relates to our drilling contracts, contract bidding, customs duties, tax appeals and other obligations in various jurisdictions. Obligations under these letters of credit are not normally called, as we typically comply with the underlying performance requirements. As of September 30, 2023, we had collateral deposits in the amount of $14.0 million with respect to these agreements.

In connection with our 50/50 unconsolidated joint venture, we have a potential obligation to fund ARO for newbuild jackup rigs. ARO has plans to purchase 20 newbuild jackup rigs over an approximate 10-year period. In January 2020, ARO ordered the first two newbuild jackups, the first of which was delivered in October 2023 and the second is expected to be delivered in the first quarter of 2024. ARO is expected to place orders for two additional newbuild jackups in the near term. The joint venture partners intend for the newbuild jackup rigs to be financed out of available cash from ARO's operations and/or funds available from third-party debt financing. In January 2020, ARO paid 25% of the purchase price from cash on hand for each of the two newbuilds ordered, and in October 2023, entered into a $359.0 million term loan to finance the remaining payments due upon delivery and for general corporate purposes. The term loan matures in eight years following the related drawdown under the term loan and requires equal quarterly amortization payments during the term, with a 50% balloon payment due at maturity. The term loan bears interest based on the three-month Secured Overnight Financing Rate (SOFR) plus a margin ranging from 1.25% to 1.4%. Our Notes Receivable from ARO are subordinated and junior in right of payment to ARO’s term loan. In the event ARO has insufficient cash from operations 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 shall be reduced by the actual cost of each newbuild rig, as delivered, on a proportionate basis. See "Note 3 - Equity Method Investment in ARO" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information on ARO.

Tax Assessments

During 2019, the Australian tax authorities issued aggregate tax assessments totaling approximately A$101.0 million ($65.0 million converted at current quarter-end exchange rates) plus interest related to the examination of certain of our tax returns for the years 2011 through 2016. During the third quarter of 2019, we made a A$42.0 million payment (approximately $29.0 million at then-current exchange rates) to the Australian tax authorities to litigate the assessment. We have a $17.5 million liability for unrecognized tax benefits relating to these assessments as of September 30, 2023. We believe our tax returns are materially correct as filed, and we are vigorously contesting these assessments. Although the outcome of such assessments and related administrative proceedings cannot be predicted with certainty, we do not expect these matters to have a material adverse effect on our financial position, operating results and cash flows.

Divestitures

Our business strategy has been to focus on ultra-deepwater floater and premium jackup operations and de-emphasize other assets and operations that are not part of our long-term strategic plan or that no longer meet our standards for economic returns. We continue to focus on our fleet management strategy in light of the composition of our rig fleet. While taking into account certain restrictions on the sales of assets under our debt agreements, as part of our strategy, we may act opportunistically from time to time to monetize assets to enhance stakeholder value and improve our liquidity profile, in addition to reducing holding costs by selling or disposing of lower-specification or non-core rigs. See “Note 8 – Debt" to our condensed consolidated financial statements included in "Item 1. Financial Statements" for additional information on restrictions on the sales of assets.

In April 2023, VALARIS 54 was sold resulting in a pre-tax gain on the sale of $27.3 million in the second quarter of 2023.

MARKET RISK

Interest Rate Risk

Our outstanding debt at September 30, 2023 consisted of our $1.1 billion aggregate principal amount of Second Lien Notes. We are subject to interest rate risk on our fixed-interest rate borrowings. Fixed rate debt, where the interest rate is fixed over the life of the instrument, exposes us to changes in market interest rates impacting the fair value of the debt.

Our Credit Agreement provides for commitments permitting borrowings of up to $375.0 million at September 30, 2023. As the interest rates for such borrowings are at variable rates, we are subject to interest rate risk. As of September 30, 2023, we had no outstanding borrowings under the Credit Agreement.

Our Notes Receivable from ARO bear interest based on a one-year LIBOR rate, set as of the end of the year prior to the year applicable, plus two percent. As the Notes Receivable from ARO bear interest on the LIBOR rate determined at the end of the preceding year, the rate governing our interest income in 2023 has already been determined. A hypothetical 1% decrease to LIBOR would decrease interest income for the year ended December 31, 2023 by $4.0 million based on the principal amount outstanding at September 30, 2023 of $402.7 million.

Foreign Currency Risk

Our functional currency is the U.S. dollar. As is customary in the oil and gas industry, a majority of our revenues and expenses are denominated in U.S. dollars; however, a portion of the revenues earned and expenses incurred by certain of our subsidiaries are denominated in currencies other than the U.S. dollar. We are exposed to foreign currency exchange risk to the extent the amount of our monetary assets denominated in the foreign currency differs from our obligations in the foreign currency or revenue earned differs from costs incurred in the foreign currency. We do not currently hedge our foreign currency risk.

46

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires us to make estimates, judgments and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Our significant accounting policies are included in Note 1 to our audited consolidated financial statements for the year ended December 31, 2022, included in our annual report on Form 10-K filed with the SEC on February 21, 2023. These policies, along with our underlying judgments and assumptions made in their application, have a significant impact on our condensed consolidated financial statements.

We identify our critical accounting policies as those that are the most pervasive and important to the portrayal of our financial position and operating results and that require the most difficult, subjective and/or complex judgments regarding estimates in matters that are inherently uncertain. Our critical accounting policies are those related to property and equipment, income taxes and pension and other post-retirement benefits. For a discussion of the critical accounting policies and estimates that we use in the preparation of our condensed consolidated financial statements, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates" in Part II of our annual report on Form 10-K for the year ended December 31, 2022.

New Accounting Pronouncements

See Note 1 - Unaudited Condensed Consolidated Financial Statements to our condensed consolidated financial statements included in "Item 1. Financial Statements" for information on new accounting pronouncements.

Item 3.   Quantitative and Qualitative Disclosures About Market Risk

Information required under this Item 3. has been incorporated herein from "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations - Market Risk."

Item 4.   Controls and Procedures

Evaluation of Disclosure Controls and Procedures – We have established disclosure controls and procedures to ensure that the information required to be disclosed by us in the reports that we file under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and made known to the officers who certify the Company’s financial reports and to other members of senior management and the board of directors as appropriate to allow timely decisions regarding required disclosure.

Based on their evaluation as of September 30, 2023, our management, with the participation of our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are effective.

Changes in Internal Controls – There were no material changes in our internal control over financial reporting during the quarter ended September 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

47

PART II - OTHER INFORMATION

Item 1.  Legal Proceedings

Environmental Matters

We are currently subject to pending notices of assessment relating to spills of drilling fluids, oil, brine, chemicals, grease or fuel from drilling rigs operating offshore Brazil from 2008 to 2019, pursuant to which the governmental authorities have assessed, or are anticipated to assess, fines. We have contested these notices and appealed certain adverse decisions and are awaiting decisions in these cases. Although we do not expect final disposition of these assessments to have a material adverse effect on our financial position, operating results and cash flows, there can be no assurance as to the ultimate outcome of these assessments. A $0.4 million liability related to these matters was included in Accrued liabilities and other on our Condensed Consolidated Balance Sheet as of September 30, 2023 included in "Item 1. Financial Statements."

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 or cash flows.

Item 1A. Risk Factors

There are numerous factors that affect our business and results of operations, many of which are beyond our control. In addition to the other information presented in this quarterly report, you should carefully read and consider "Item 1A. Risk Factors" in Part I and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II of our annual report on Form 10-K for the year ended December 31, 2022, and "Item 1A. Risk Factors" in Part II of our Quarterly Report on Form 10-Q for the quarterly period March 31, 2023, which contains descriptions of significant risks that may cause our actual results of operations in future periods to differ materially from those currently anticipated or expected.

Item 2.   Unregistered Sales of Equity Securities and Use of Proceeds

In 2022, our board of directors authorized a share repurchase program under which we may purchase up to $100.0 million of our outstanding Common Shares. In April 2023, the board of directors authorized an increase of this amount to $300.0 million. The share repurchase program does not have a fixed expiration, may be modified, suspended or discontinued at any time and is subject to compliance with applicable covenants and restrictions under our financing agreements.

Total	1.2	$	73.30	1.2	$	150.0

Item 5.   Other Information

During the three months ended September 30, 2023, no director or officer of the Company adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408(a) of Regulation S-K.

As disclosed in prior filings, in August 2017, one of our Brazilian subsidiaries was contacted by the Federal Prosecutor’s Office in the State of Paraná in connection with a criminal investigation procedure initiated against agents of both Samsung Heavy Industries, a shipyard in South Korea, and Pride International LLC, a legacy Valaris entity, ("Pride") in relation to the drilling services agreement with Petrobras for VALARIS DS-5 (the "DSA"). The Brazilian authorities requested information regarding our compliance program and the findings of our internal investigations relating to the DSA. We cooperated with the Federal Prosecutor’s Office and provided documents in response to its request.

In October 2023, we were informed that the Coordination Chamber of the Brazilian Federal Prosecutor's Offices had formally closed the criminal investigation with no accusations of wrongdoing being brought against former employees of Pride. We cannot predict whether any Brazilian governmental authority will open any further investigation into Pride’s involvement in this matter, or if an additional proceeding were opened, the scope or ultimate outcome of any such investigation.

While this closes the criminal investigation, the Brazil administrative proceeding with the Federal Court of Accounts is ongoing. For more information, see "Note 11 - Contingencies" to our consolidated financial statements included in "Item 1. Financial Statements."

Unaudited Condensed Consolidated Financial Statements

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Unaudited Condensed Consolidated Financial Statements

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, 2022 Condensed Consolidated Balance Sheet data was derived from our 2022 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, 2023 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2023, 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, 2022, filed with the SEC on February 21, 2023 (our "Annual Report").

Summary of Significant Accounting Policies

Please refer to "Note 1. Description of the Business and Summary of Significant Accounting Policies" of our Consolidated Financial Statements from our Annual Report for the discussion of our significant accounting policies. Certain previously reported amounts have been reclassified to conform to the current year presentation.

New Accounting Pronouncements

Recently adopted accounting pronouncements

Business Combinations - In October 2021, the FASB issued ASU No. 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” (“Update 2021-08”). ASU No. 2021-08 requires an entity (acquirer) to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 and provides practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. The amendments also apply to contract assets and contract liabilities from other contracts to which the provisions of Topic 606 apply, such as contract liabilities for the sale of nonfinancial assets within the scope of Subtopic 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets. The FASB issued the update to improve the accounting for acquired revenue contracts with customers in a business combination. Update 2021-08 is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption permitted. We adopted Update 2021-08 effective January 1, 2023 with no material impact to our condensed consolidated financial statements upon adoption.

Accounting pronouncements to be adopted

Reference Rate Reform - In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("Update 2020-04"), which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in Update 2020-04 apply only to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, for which an entity has elected certain optional expedients and that are retained through the end of the hedging relationship. The provisions in Update 2020-04 are effective upon issuance and can be applied prospectively through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, to extend the temporary accounting rules under Topic 848 from December 31, 2022, to December 31, 2024. Our long-term notes receivable from ARO, from which we generate interest income on a LIBOR-based rate (the "Notes Receivable from ARO"), are impacted by the application of this standard. As the Notes Receivable from ARO bear interest on the LIBOR rate determined at the end of the preceding year, the rate governing our interest income in 2023 has already been determined. We expect to be able to modify the terms of our Notes Receivable from ARO to a comparable interest rate before the applicable LIBOR rate is no longer available and as such, do not expect this standard to have a material impact to our condensed consolidated financial statements.

With the exception of the updated standards 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.

Revenue from Contracts with Customers

9 Months Ended

Sep. 30, 2023

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

Revenue from Contracts with Customers

Our drilling contracts with customers provide a drilling rig and drilling services on a day rate contract basis. Under day rate contracts, we provide a drilling rig and rig crews for which 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, 2023 was between approximately 1 month and 5 years.

Contract Termination - VALARIS DS-11

In 2021, a contract was awarded to VALARIS DS-11 for a project in the U.S. Gulf of Mexico that was expected to commence in mid-2024. In June 2022, the customer terminated the contract. As a result of the contract termination, we received an early termination fee of $51.0 million which is included in revenues on our Condensed Consolidated Statements of Operations for the nine months ended September 30, 2022.

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.

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, 2023, ARO owns seven jackup rigs, has two newbuild jackup rigs on order, and leases eight rigs from us through bareboat charter arrangements (the "Lease Agreements") whereby substantially all operating costs are incurred by ARO.

ARO has plans to purchase 20 newbuild jackup rigs over an approximate 10-year period. In January 2020, ARO ordered the first two newbuild jackups, the first of which was delivered in October 2023 and the second is expected to be delivered in the first quarter of 2024. ARO is expected to place orders for two additional newbuild jackups in the near term. In connection with these plans, we have a potential obligation to fund ARO for newbuild jackup rigs. See "Note 11 - Contingencies" for additional information.

Summarized Financial Information

The operating revenues of ARO presented below reflect revenues earned under drilling contracts with Saudi Aramco for the ARO-owned jackup rigs as well as the rigs leased from us. Contract drilling expense is inclusive of the bareboat charter fees for the rigs leased from us. See additional discussion below regarding these related-party transactions.

Equity in Earnings 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, adjusted for basis differences as discussed below, in Equity in earnings 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 the chapter 11 cases on April 30, 2021 (the "Effective Date") and also on the date of our 2019 transaction where we acquired the subsidiary that held the joint venture interest. 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") on each of these dates. 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 dates.

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 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. A reconciliation of those components is presented below (in millions):

	Three Months Ended September 30,				Nine Months Ended September 30,

Upon completion of the lease term, such amount becomes a payable to or a receivable from ARO.

During 2017 and 2018, the Company contributed cash to ARO in exchange for the 10-year Notes Receivable from ARO based on a one-year LIBOR rate, set as of the end of the year prior to the year applicable, plus two percent. The Notes Receivable from ARO were adjusted to the estimated fair value as of the Effective Date 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.

Earnings (Loss) 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, 2023 and 2022 (in millions):

	Three Months Ended September 30,				Nine Months Ended September 30,

Diluted	74.8		75.6		75.7		75.5

Anti-dilutive share awards totaling 35,000 and 104,000 were excluded from the computation of diluted EPS for the three and nine months ended September 30, 2023, respectively.

Anti-dilutive share awards totaling 38,000 and 103,000 were excluded from the computation of diluted EPS for the three and nine months ended September 30, 2022, respectively.

We had 5,470,950 warrants outstanding (the "Warrants") as of September 30, 2023 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.

First Lien Notes

On April 3, 2023, the Company issued a notice of conditional redemption to the holders of the Senior Secured First Lien Notes due 2028 (the "First Lien Notes") at a redemption price equal to 104.0% of the aggregate $550.0 million principal amount of the First Lien Notes plus accrued and unpaid interest to, but not including, the redemption date (the “Redemption Price”). On April 19, 2023, in connection with the issuance of our Second Lien Notes, as discussed below, the Company discharged its obligations under the indenture governing the First Lien Notes and deposited the Redemption Price with Wilmington Savings Fund Society, as trustee under such indenture. The First Lien Notes were redeemed on May 3, 2023 for an aggregate redemption price of $571.8 million (excluding accrued and unpaid interest). We accounted for the redemption as an extinguishment of debt and reported a corresponding loss of $29.2 million in the second quarter of 2023, which is included in our Condensed Consolidated Statements of Operations for the nine months ended September 30, 2023.

Second Lien Notes

On April 19, 2023, the Company and Valaris Finance Company LLC (“Valaris Finance”), a wholly-owned subsidiary, issued and sold $700.0 million aggregate principal amount of Second Lien Notes (the "Initial Second Lien Notes") in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act of

1933, as amended (the “Securities Act”). The Initial Second Lien Notes were issued at par for net proceeds of $681.4 million, after deducting the initial purchasers’ discount and offering expenses. A portion of the proceeds were used to fund the redemption of all of the outstanding First Lien Notes as discussed above.

On August 21, 2023, the Company and Valaris Finance issued $400.0 million aggregate principal amount of additional Second Lien Notes (the "Additional Notes") in a private placement conducted pursuant to Rule 144A and Regulation S under the Securities Act. The Additional Notes were issued at 100.75% of par, plus accrued interest from April 19, 2023. The net proceeds were approximately $396.9 million after deducting the initial purchasers’ discount and estimated offering expenses, and excluding accrued interest received of $11.4 million.

The Initial Second Lien Notes and the Additional Notes were issued under the Indenture, dated as of April 19, 2023 (the "Indenture"), and mature on April 30, 2030. The Second Lien Notes bear an interest rate of 8.375% per annum with an effective interest rate of 8.76%. Interest is payable semi-annually in arrears on April 30 and October 30 of each year, beginning on October 30, 2023. The Second Lien Notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by the Guarantors and by each of the Company’s future restricted subsidiaries (other than Valaris Finance) that guarantees any debt of the Issuers or any guarantor under certain future debt in an aggregate principal amount in excess of a certain amount. The Second Lien Notes and the related guarantees are secured on a second-priority basis by the Collateral (as defined below).

On or after April 30, 2026, the Issuers may, at their option, redeem all or any portion of the Second Lien Notes, at once or over time, at the redemption prices set forth below, plus accrued and unpaid interest, if any, to, but not including, the redemption date. The following prices are for Second Lien Notes redeemed during the 12-month period commencing on April 30 of the years set forth below, and are expressed as percentages of principal amount:

Redemption Year	Price
2026	104.188%
2027	102.094%
2028 and thereafter	100.000%

At any time prior to April 30, 2026, the Issuers may, on any one or more occasions, redeem up to 40.0% of the aggregate principal amount of the Second Lien Notes issued under the Indenture (including any additional Second Lien Notes issued in the future) with an amount equal to or less than the net cash proceeds of certain equity offerings, at a redemption price equal to 108.375% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to but not including, the redemption date. In addition, at any time prior to April 30, 2026, the Issuers may redeem up to 10.0% of the aggregate principal amount of the Second Lien Notes during any twelve-month period at a redemption price equal to 103.0% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the redemption date.

At any time prior to April 30, 2026, the Issuers may redeem some or all of the Second Lien Notes at a price equal to 100.0% of the principal amount of the Second Lien Notes redeemed, plus accrued and unpaid interest, if any, to, but not including, the redemption date, plus a “make-whole” premium.

The Indenture contains covenants that, among other things, restrict the Company’s ability and the ability of certain of its subsidiaries to: (i) incur additional debt and issue certain preferred stock; (ii) incur or create liens; (iii) make certain distributions, investments and other restricted payments; (iv) sell or otherwise dispose of certain assets; (v) engage in certain transactions with affiliates; and (vi) merge, consolidate, amalgamate or sell, transfer, lease or otherwise dispose of all or substantially all of the Company’s assets. These covenants are subject to important exceptions and qualifications. In addition, many of these covenants will be suspended with respect to the Second Lien Notes during any time that the Second Lien Notes have investment grade ratings from at least two rating agencies and no default with respect to the Second Lien Notes has occurred and is continuing. As of September 30, 2023, we were in compliance with our covenants under the Indenture.

Upon the occurrence of certain Change of Control Triggering Event (as defined in the Indenture), the Issuers may be required to make an offer to repurchase all of the Second Lien Notes then outstanding at a price equal to 101.0% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the repurchase date.

Senior Secured Revolving Credit Facility

On April 3, 2023, the Company entered into a senior secured revolving credit agreement (the “Credit Agreement”). The Credit Agreement provides for commitments permitting borrowings of up to $375.0 million (which may be increased, subject to the satisfaction of certain conditions and the agreement of lenders to provide such additional commitments, by an additional $200.0 million pursuant to the terms of the 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 (together with Valaris Finance, the “Guarantors”) guarantee the Company’s obligations under the Credit Agreement, and the lenders have a first priority lien on the assets securing the Credit Agreement. The commitments under the Credit Agreement became available to be borrowed on April 19, 2023 (the "Availability Date").

The Credit Agreement and the related guarantees are secured on a first-priority basis, subject to permitted liens, by (a) first preferred ship mortgages over each vessel owned by us and the Guarantors as of the Availability Date, with certain exceptions (the “Collateral Vessels”); (b) first priority assignments of certain insurances and requisition compensation in respect of the Collateral Vessels; (c) first priority pledges of all equity interests in our subsidiaries that own Collateral Vessels and certain subsidiaries that hold equity interests in entities that own vessels (the “Collateral Rig Owners”); (d) first priority assignments of earnings of the Collateral Vessels from the Collateral Rig Owners; (e) any vessels and other assets of ours and the Guarantors that are pledged, at our option, to secure the Credit Agreement; and (f) all proceeds thereof (the "Collateral").

Amounts borrowed under the 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 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.

In addition to paying interest on outstanding borrowings under the Credit Agreement, we are required to pay a quarterly commitment fee to the lenders under the 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 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. We are also required to pay customary agency fees in respect of the Credit Agreement.

The Credit Agreement contains various covenants that limit, among other things, our and our restricted subsidiaries’ ability to: incur indebtedness; grant liens; dispose of certain assets; make certain acquisitions and investments; redeem or prepay other debt or make other restricted payments such as distributions to shareholders; enter into transactions with affiliates; enter into sale-leaseback transactions; and enter into a merger, amalgamation, consolidation or sale of assets. Further, the Credit Agreement contains financial covenants that require us to maintain (i) a minimum book value of equity to total assets ratio, (ii) a minimum interest coverage ratio and (iii) a minimum amount of liquidity.

As of September 30, 2023, we were in compliance in all material respects with our covenants under the Credit Agreement. We had no amounts outstanding under the Credit Agreement as of September 30, 2023.

Share Repurchase Program

In 2022, our board of directors authorized a share repurchase program under which we may purchase up to $100.0 million of our outstanding Common Shares. In April 2023, the board of directors authorized an increase of this amount to $300.0 million. The share repurchase program does not have a fixed expiration, may be modified, suspended or discontinued at any time and is subject to compliance with applicable covenants and restrictions under our financing agreements. During the three months ended September 30, 2023, we repurchased 1.2 million shares at an aggregate cost of $85.0 million at an average price of $73.30. During the nine months ended September 30, 2023, we repurchased 2.3 million shares at an aggregate cost of $150.0 million at an average price of $66.24.

Income Taxes

Components of Income Tax Expense (Benefit), Continuing Operations [Abstract]

Income Taxes

Income Taxes

Historically, we calculated our provision for income taxes during interim reporting periods by applying the estimated annual effective tax rate for the full fiscal year to pre-tax income or loss, excluding discrete items, for the reporting period. We determined that since small changes in estimated pre-tax income or loss would result in significant changes in the estimated annual effective tax rate, the historical method would not provide a reliable estimate of income taxes for the three and nine months ended September 30, 2023 and 2022, and therefore, we used a discrete effective tax rate method to calculate income taxes for each of these periods. We will continue to evaluate income tax estimates under the historical method in subsequent quarters and employ a discrete effective tax rate method if warranted.

Discrete income tax benefit for the three months ended September 30, 2023 was $2.0 million and was primarily attributable to the resolution of prior period tax matters, partially offset by changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years. Discrete income tax benefit of $39.5 million for the nine months ended September 30, 2023 was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and the resolution of other prior period tax matters. Excluding the aforementioned discrete tax items, income tax expense for the three and nine months ended September 30, 2023 was $12.7 million and $47.1 million, respectively.

A substantial portion of our deferred tax assets are subject to a valuation allowance. During the three months ended September 30, 2023, we recognized a $6.2 million deferred tax benefit from the reduction of valuation allowances on deferred tax assets for a change in estimated future taxable income in certain operating jurisdictions. We intend to continue maintaining a valuation allowance on a substantial portion of our deferred tax assets until there is sufficient evidence to support a reversal of such allowances. However, given the current operating environment and our anticipated future earnings, we believe there is a reasonable possibility that sufficient positive evidence may become available to allow us to reach a conclusion that a portion of the valuation allowance on deferred tax assets will no longer be needed. A reduction in our valuation allowance would result in the recognition of a deferred tax benefit during the period in which the reduction is recognized. The timing and amount of future valuation allowance reductions are subject to future levels of contracting and profitability achieved.

Discrete income tax expense for the three months ended September 30, 2022 was $1.4 million and was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years, partially offset by discrete tax benefits attributable to the resolution of other prior period tax matters. Discrete income tax benefit for the nine months ended September 30, 2022 was $6.9 million and was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and resolution of other prior period tax matters, partially offset by discrete tax expense attributable to income associated with a contract termination. Excluding the aforementioned discrete tax items, income tax expense for the three and nine months ended September 30, 2022 was $12.4 million and $40.2 million, respectively.

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. ARO has plans to purchase 20 newbuild jackup rigs over an approximate 10-year period. The joint venture partners intend for the newbuild jackup rigs to be financed out of available cash from ARO's operations and/or funds available from third-party debt financing. In January 2020, ARO paid 25% of the purchase price from cash on hand for each of the two newbuilds, and in October 2023, entered into a $359.0 million term loan to finance the remaining payments due upon delivery and for general corporate purposes. The term loan matures in eight years following the related drawdown under the term loan and requires equal quarterly amortization payments during the term, with a 50% balloon payment due at maturity. The term loan bears interest based on the three-month Secured Overnight Financing Rate (SOFR) plus a margin ranging from 1.25% to 1.4%. Our Notes Receivable from ARO are subordinated and junior in right of payment to ARO’s term loan. In the event ARO has insufficient cash from operations 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 shall be reduced by the actual cost of each newbuild rig, as delivered, on a proportionate basis.

Letters of Credit

In the ordinary course of business with customers and others, we have entered into letters of credit 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 outstanding as of September 30, 2023 totaled $95.8 million and are issued under facilities provided by various banks and other financial institutions, but none were issued under the Credit Agreement. Obligations under these letters of credit are not normally called, as we typically comply with the underlying performance requirements. As of September 30, 2023, we had collateral deposits in the amount of $14.0 million with respect to these agreements.

Patent Litigation

In December 2022, a subsidiary of Transocean Ltd. commenced an arbitration proceeding against us alleging breach of a license agreement related to certain dual-activity drilling patents. We are unable to estimate our potential exposure, if any, to the proceeding at this time but do not believe that our ultimate liability, if any, resulting from this proceeding will have a material effect on our consolidated financial condition, results of operations or cash flows. We do not believe that we have breached the license agreement and intend to defend ourselves vigorously against this claim.

Brazil Administrative Proceeding

In July 2023, we received notice of an administrative proceeding initiated against us in Brazil. Specifically, the Federal Court of Accounts ("TCU") is seeking from us, Samsung Heavy Industries (“SHI”) and others, on a joint and several basis, a total of approximately BRL 601 million (approximately $120.0 million at the current quarter-end exchange rates) in damages that TCU asserts arose from the overbilling to Petrobras in 2015 in relation to the drilling services agreement with Petrobras for VALARIS DS-5 (the “DSA”). As fully disclosed in our prior periodic reports, the DSA was previously the subject of (1) investigations by the SEC and the U.S Department of Justice, each of which closed their investigation of us in 2018 without any enforcement action, (2) an arbitration proceeding against SHI in which we prevailed resulting in SHI making a $200.0 million cash payment to us in December 2019, and (3) a settlement with Petrobras normalizing our business relations in August 2018. We plan to vigorously defend ourselves against the allegations made by the TCU. Because these proceedings are in their initial stages, we are unable to estimate our potential exposure, if any, at this time.

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 Information, Revenue for Reportable Segment [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 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 expense and Depreciation expense 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 deducted under "Reconciling Items" and replaced with our equity in earnings of ARO. See "Note 3 - Equity Method Investment in ARO" for additional information on ARO and related arrangements.

We received an income tax refund of $45.9 million during the first quarter of 2023 related to the U.S. Coronavirus Aid, Relief, and Economic Security Act.

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 or nine months ended September 30, 2023, and 2022 were as follows:

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, 2022 Condensed Consolidated Balance Sheet data was derived from our 2022 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, 2023 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2023, 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, 2022, filed with the SEC on February 21, 2023 (our "Annual Report").

New Accounting Pronouncements

New Accounting Pronouncements

Recently adopted accounting pronouncements

Business Combinations - In October 2021, the FASB issued ASU No. 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” (“Update 2021-08”). ASU No. 2021-08 requires an entity (acquirer) to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 and provides practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. The amendments also apply to contract assets and contract liabilities from other contracts to which the provisions of Topic 606 apply, such as contract liabilities for the sale of nonfinancial assets within the scope of Subtopic 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets. The FASB issued the update to improve the accounting for acquired revenue contracts with customers in a business combination. Update 2021-08 is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption permitted. We adopted Update 2021-08 effective January 1, 2023 with no material impact to our condensed consolidated financial statements upon adoption.

Accounting pronouncements to be adopted

Reference Rate Reform - In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("Update 2020-04"), which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in Update 2020-04 apply only to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, for which an entity has elected certain optional expedients and that are retained through the end of the hedging relationship. The provisions in Update 2020-04 are effective upon issuance and can be applied prospectively through December 31, 2022. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, to extend the temporary accounting rules under Topic 848 from December 31, 2022, to December 31, 2024. Our long-term notes receivable from ARO, from which we generate interest income on a LIBOR-based rate (the "Notes Receivable from ARO"), are impacted by the application of this standard. As the Notes Receivable from ARO bear interest on the LIBOR rate determined at the end of the preceding year, the rate governing our interest income in 2023 has already been determined. We expect to be able to modify the terms of our Notes Receivable from ARO to a comparable interest rate before the applicable LIBOR rate is no longer available and as such, do not expect this standard to have a material impact to our condensed consolidated financial statements.

With the exception of the updated standards 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.
