Noble Finance Company [Member]
Organization and Basis of Presentation	Note 1—Organization and Significant Accounting Policies Noble Corporation, an exempted company incorporated in the Cayman Islands with limited liability (“Noble” or “Successor”), is a leading offshore drilling contractor for the oil and gas industry. We provide contract drilling services to the international oil and gas industry with our global fleet of mobile offshore drilling units. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921. As of December 31, 2021, our fleet of 20 drilling rigs consisted of 12 floaters and eight We report our contract drilling operations as a single On July 31, 2020 (the “Petition Date”), our former parent company, Noble Holding Corporation plc (formerly known as Noble Corporation plc), a public limited company incorporated under the laws of England and Wales (“Legacy Noble” or the “Predecessor”), and certain of its subsidiaries, including Noble Finance Company (formerly known as Noble Corporation), a Cayman Islands company (“Finco”), filed voluntary petitions in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”) seeking relief under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”). On September 4, 2020, the Debtors (as defined herein) filed with the Bankruptcy Court the Joint Plan of Reorganization of Noble Corporation plc and its Debtor Affiliates, six Noble Corporation plc, No. 20-33826) The Noble is the successor issuer to Legacy Noble for purposes of and pursuant to Rule 15d-5 Upon emergence, the Company applied fresh start accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 852 – Reorganizations (“ASC 852”). The application of fresh start accounting resulted in a new basis of accounting and the Company becoming a new entity for financial reporting purposes. Accordingly, our financial statements and notes after the Effective Date are not comparable to our financial statements and notes on and prior to that date. See “Note 3—Fresh Start Accounting” for additional information. Finco was an indirect, wholly-owned subsidiary of Legacy Noble prior to the Effective Date and has been a direct, wholly-owned subsidiary of Noble, our parent company, since the Effective Date. Noble’s principal asset is all of the shares of Finco. Finco has no public equity outstanding. The consolidated financial statements of Noble include the accounts of Finco, and Noble conducts substantially all of its business through Finco and its subsidiaries. As such, the terms “Predecessor” and “Successor” also refers to Finco, as the context requires. Principles of Consolidation The consolidated financial statements include our accounts and those of our wholly-owned subsidiaries and entities in which we hold a controlling financial interest. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our consolidated financial statements. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits with banks and all highly liquid investments with original maturities of three months or less. Our cash, cash equivalents and short-term investments are subject to potential credit risk, and certain of our cash accounts carry balances greater than the federally insured limits. Cash and cash equivalents are primarily held by major banks or investment firms. Our cash management and investment policies restrict investments to lower risk, highly liquid securities and we perform periodic evaluations of the relative credit standing of the financial institutions with which we conduct business. Restricted Cash We classify restricted cash balances in current assets if the restriction is expected to expire or otherwise be resolved within one year and in other assets if the restriction is expected to expire or otherwise be resolved in more than one year. As of December 31, 2021 and 2020, our Noble restricted cash balance consisted of $2.6 million and $21.7 million, respectively. As of December 31, 2021 and 2020, our Finco restricted cash balance consisted of $2.6 million and $1.7 million, respectively. All restricted cash is recorded in “Prepaid expenses and other current assets.” As of December 31, 2021, our restricted cash balance was associated cash collateral on the Company’s purchase cards and a performance guarantee on the Noble Faye Kozack Accounts Receivable We record accounts receivable at the amount we invoice our clients, net of allowance for credit losses. We provide an allowance for uncollectible accounts, as necessary. Our allowance for doubtful accounts as of December 31, 2021 and 2020 was zero and $1.1 million, respectively. Property and Equipment Property and equipment is stated at cost, reduced by provisions to recognize economic impairment. Major replacements and improvements are capitalized. When assets are sold, retired or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and the gain or loss is recognized. Drilling equipment and facilities are depreciated using the straight-line method over their estimated useful lives as of the date placed in service or date of major refurbishment. Estimated useful lives of our drilling equipment range from three two Interest is capitalized on long-term construction project using the weighted average cost of debt outstanding during the period of construction. Scheduled maintenance of equipment is performed based on the number of hours operated in accordance with our preventative maintenance program. Routine repair and maintenance costs are charged to expense as incurred; however, the costs of the overhauls and asset replacement projects that benefit future periods and which typically occur every three five We evaluate our property and equipment for impairment whenever there are changes in facts that suggest that the value of the asset is not recoverable. As part of this analysis, we make assumptions and estimates regarding future market conditions. When circumstances indicate that the carrying value of the assets may not be recoverable, management compares the carrying value to the expected undiscounted pre-tax pre-tax Fair Value Measurements We measure certain of our assets and liabilities based on a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The three-level hierarchy, from highest to lowest level of observable inputs, are as follows: Level 1 - Valuations based on quoted prices in active markets for identical assets; Level 2 - Valuations based on observable inputs that do not meet the criteria for Level 1, including quoted prices in inactive markets and quoted prices in active markets for similar but not identical instruments; and Level 3 - Valuations based on unobservable inputs. Revenue Recognition The activities that primarily drive the revenue earned in our drilling contracts include (i) providing a drilling rig and the crew and supplies necessary to operate the rig, (ii) mobilizing and demobilizing the rig to and from the drill site, and (iii) performing rig preparation activities and/or modifications required for the contract. Consideration received for performing these activities may consist of dayrate drilling revenue, mobilization and demobilization revenue, contract preparation revenue and reimbursement revenue. We account for these integrated services provided within our drilling contracts as a single performance obligation satisfied over time and comprised of a series of distinct time increments in which we provide drilling services. Our standard drilling contracts require that we operate the rig at the direction of the customer throughout the contract term (which is the period we estimate to benefit from the corresponding activities and generally ranges from two The amount estimated for variable consideration may be subject to interrupted or restricted rates and is only included in the transaction price to the extent that it is probable that a significant reversal of previously recognized revenue will not occur throughout the term of the contract (“constrained revenue”). When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue as well as the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed Dayrate Drilling Revenue. Mobilization/Demobilization Revenue. lump-sum pre-operating pre-operating In most contracts, there is uncertainty as to the amount of expected demobilization revenue due to contractual provisions that stipulate that certain conditions must be present at contract completion for such revenue to be received and as to the amount thereof, if any. For example, contractual provisions may require that a rig demobilize a certain distance before the demobilization revenue is payable or the amount may vary dependent upon whether or not the rig has additional contracted work within a certain distance from the wellsite. Therefore, the estimate for such revenue may be constrained, as described earlier, depending on the facts and circumstances pertaining to the specific contract. We assess the likelihood of receiving such revenue based on past experience and knowledge of the market conditions. In cases where demobilization revenue is expected to be received upon contract completion, it is estimated as part of the overall transaction price at contract inception and recognized in earnings ratably over the initial term of the contract with an offset to an accretive contract asset. Contract Preparation Revenue. lump-sum Bonuses, Penalties and Other Variable Consideration. re-measure Capital Modification Revenue lump-sum Revenues Related to Reimbursable Expenses Deferred revenues from drilling contracts totaled $27.8 million and $59.9 million at December 31, 2021 and 2020, respectively. Such amounts are included in either “Other current liabilities” or “Other liabilities” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition. Related expenses deferred under drilling contracts totaled $5.7 million at December 31, 2021 as compared to $13.9 million at December 31, 2020 and are included in either “Prepaid expenses and other current assets,” “Other assets” or “Property and equipment, net” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition. We record reimbursements from customers for “out-of-pocket” Income Taxes Income taxes are based on the laws and rates in effect in the countries in which operations are conducted or in which we or our subsidiaries are considered resident for income tax purposes. In certain circumstances, we expect that, due to changing demands of the offshore drilling markets and the ability to redeploy our offshore drilling units, certain of such units will not reside in a location long enough to give rise to future tax consequences. As a result, no deferred tax asset or liability has been recognized in these circumstances. Should our expectations change regarding the length of time an offshore drilling unit will be used in a given location, we will adjust deferred taxes accordingly. Deferred tax assets and liabilities are recognized for the anticipated future tax effects of temporary differences between the financial statement basis and the tax basis of our assets and liabilities using the applicable jurisdictional tax rates at year-end. We operate through various subsidiaries in numerous countries throughout the world, including the United States. Consequently, we are subject to changes in tax laws, treaties or regulations or the interpretation or enforcement thereof in the United States, UK and any other jurisdictions in which we or any of our subsidiaries operate or are resident. Our income tax expense is based upon our interpretation of the tax laws in effect in various countries at the time that the expense was incurred. If the IRS or other taxing authorities do not agree with our assessment of the effects of such laws, treaties and regulations, this could have a material adverse effect on us including the imposition of a higher effective tax rate on our worldwide earnings or a reclassification of the tax impact of our significant corporate restructuring transactions. The Company has adopted an accounting policy to look through the outside basis of partnerships and all other flow-through entities and exclude these from the computation of deferred taxes. Insurance Reserves We maintain various levels of self-insured retention for certain losses including property damage, loss of hire, employment practices liability, employers’ liability and general liability, among others. We accrue for property damage and loss of hire charges on a per event basis. Employment practices liability claims are accrued based on actual claims during the year. Maritime employer’s liability claims are generally estimated using actuarial determinations. General liability claims are estimated by our internal claims department by evaluating the facts and circumstances of each claim (including incurred but not reported claims) and making estimates based upon historical experience with similar claims. At December 31, 2021 and 2020, loss reserves for personal injury and protection claims totaled $14.8 million and $30.9 million, respectively, and such amounts are included in “Other current liabilities” and “Other current liabilities” or “Liabilities subject to compromise,” respectively, in the accompanying Consolidated Balance Sheets. Earnings per Share Our unvested share-based payment awards, which contain non-forfeitable two-class two-class two-class Share-Based Compensation Plans We record the grant date fair value of share-based compensation arrangements as compensation cost using a straight-line method over the service period. Share-based compensation is expensed or capitalized based on the nature of the employee’s activities. Liability-Classified Awards The Company classified certain awards that will be settled in cash as liability awards. The fair value of a liability-classified award is determined on a quarterly basis beginning at the grant date until final vesting. Changes in the fair value of liability-classified awards are expensed or capitalized based on the nature of the employee’s activities over the vesting period of the award. Litigation Contingencies We are involved in legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. Certain of these matters include speculative claims for substantial or indeterminate amounts of damages. We record a liability when we believe that it is both probable that a loss has been incurred and the amount can be reasonably estimated. If we determine that a loss is reasonably possible and the loss or range of loss can be estimated, we disclose the possible loss in the notes to the consolidated financial statements. We review the developments in our contingencies that could affect the amount of the provisions that has been previously recorded, and the matters and related possible losses disclosed. We make adjustments to our provisions and changes to our disclosures accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Significant judgement is required to determine both the probability and the estimated amount. Foreign Currency Translation Although we are a Cayman Islands company, our functional currency is the US dollar, and we define any non-US non-US currency transaction gains and losses are included in net income or loss. In non-US Discontinued Operations On August 1, 2014, Legacy Noble completed the separation and spin-off “Spin-off”) Spin-off, Prior to the completion of the Spin-off, Spin-off Spin-off Spin-off. Spin-off, Accounting Pronouncements Accounting Standards Adopted In December 2019, the FASB issued Accounting Standards Update (“ASU”) No. 2019-12, We adopted ASU No. 2019-12, Recently Issued Accounting Standards In October 2021, the FASB issued ASU No. 2021-08, With the exception of the updated standards discussed above, there have been no new accounting pronouncements not yet effective that have significance, or potential significance, to our consolidated financial statements.

Fresh Start Accounting

Fresh Start Accounting	11 Months Ended
	Dec. 31, 2021
Noble Finance Company [Member]
Fresh Start Accounting	Note 3—Fresh Start Accounting In connection with our emergence from bankruptcy and in accordance with ASC 852, Noble and Finco qualified for and applied fresh start accounting on the Effective Date. Noble and Finco were required to apply fresh start accounting because (i) the holders of existing Legacy Noble voting shares received less than 50% of the voting shares of the Successor, and (ii) the reorganization value of Noble’s and Finco’s assets, each of which approximated $1.7 billion, immediately prior to confirmation of the Plan was less than the corresponding post-petition liabilities and allowed claims, each of which approximated $4.0 billion. Applying fresh start accounting resulted in new reporting entities with no beginning retained earnings or accumulated deficit. Accordingly, our financial statements and notes after the Effective Date are not comparable to our financial statements and notes on and to prior to that date. With the application of fresh start accounting, we allocated the reorganization value to our individual assets and liabilities (except for deferred income taxes) based on their estimated fair values in conformity with ASC Topic 805, Business Combinations. The amount of deferred taxes was determined in accordance with ASC Topic 740, Income Taxes and ASC 852. The Effective Date fair values of our assets and liabilities differed materially from their recorded values as reflected on the historical balance sheets. As described in “Note 1—Organization and Significant Accounting Policies,” Noble and Finco are referred to as Successor, as the context requires, and includes the financial position and results of operations of the reorganized Noble and Finco subsequent to February 5, 2021. References to Predecessor relate to the financial position and results of operations of Legacy Noble and Finco prior to, and including, February 5, 2021. Reorganization Value and Valuation of Assets The reorganization value represents the fair value of the Successor’s and Finco’s total assets and was derived from the enterprise value, which represents the estimated fair value of an entity’s long-term debt and equity. As set forth in the Plan, the enterprise value of the reorganized Debtors was estimated to be in the range of $1.1 billion to $1.6 billion with a midpoint of $1.3 billion. The enterprise value range was determined by using a discounted cash flow analysis and a peer group trading analysis, excluding unrestricted cash at emergence. Based on the estimates and assumptions discussed above, we estimated the enterprise value to be the midpoint of the range of estimated enterprise value of $1.3 billion.​​​​​​​ The following table reconciles the enterprise value to the Successor equity as of the Effective Date: February 5, 2021 Enterprise Value $ 1,300,300 Plus: Cash and cash equivalents 111,968 Less: Fair value of debt (393,500 ) Fair Value of Successor Equity $ 1,018,768 The following table reconciles the enterprise value to the reorganization value as of the Effective Date: February 5, 2021 Enterprise Value $ 1,300,300 Plus: Cash and cash equivalents 111,968 Plus: Non-interest 185,410 Plus: Non-interest non-current 108,268 Reorganization value of Successor assets $ 1,705,946 With the assistance of financial advisors, we determined the enterprise and corresponding equity value of the Successor by calculating the present value of future cash flows based on our financial projections. The enterprise value and corresponding equity value are dependent upon achieving future financial results set forth in our valuations, as well as the realization of certain other assumptions. All estimates, assumptions, valuations and financial projections, including the fair value adjustments, the enterprise value and equity value projections, are inherently subject to significant uncertainties and the resolution of contingencies beyond our control. Accordingly, the estimates, assumptions, valuations or financial projections may not be realized and actual results could vary materially. Valuation Process Under the application of fresh start accounting and with the assistance of valuation experts, we conducted an analysis of the Consolidated Balance Sheet to determine if any of the Company’s net assets would require a fair value adjustment as of the Effective Date. The results of our analysis indicated that our principal assets, which include mobile offshore drilling units, certain intangibles and debt issued at emergence would require a fair value adjustment on the Effective Date. The rest of the Company’s net assets were determined to have carrying values that approximated fair value on the Effective Date. Further details regarding the valuation process is described further below. Property, Plant and Equipment The valuation of the Company’s mobile offshore drilling units and other related tangible assets was determined by using a combination of (1) the discounted cash flows expected to be generated from our drilling assets over their remaining useful lives and (2) the cost to replace our drilling assets, as adjusted by the current market for similar offshore drilling assets. Assumptions used in our assessment included, but were not limited to, future marketability of each unit in light of the current market conditions and its current technical specifications, timing of future contract awards and expected operating dayrates, operating costs, utilization rates, tax rates, discount rate, capital expenditures, market values, weighting of market values, reactivation costs, estimated economic useful lives and, in certain cases, our belief that a drilling unit is no longer marketable and is unlikely to return to service in the near to medium term. We included an allocation for corporate overhead when calculating the discounted cash flows expected to be generated from our drilling assets over their remaining useful lives. The cash flows were discounted at our weighted average cost of capital (“WACC”), which was derived from a blend of our after-tax The valuation of our remaining property and equipment, including owned real estate, construction in progress assets, and other equipment essential to our operations, was determined utilizing a combination of replacement cost and market valuation approaches. Specifically, the land was valued using a sales comparison method of the market approach, in which we utilized recent sales of comparable properties to estimate the fair value on a US Dollar per acre basis. The remaining property and equipment were valued using a cost approach, in which we estimated the replacement cost of the assets and applied adjustments for physical depreciation and obsolescence, where applicable, to arrive at a fair value. Intangible Assets At emergence, we held contracts for drilling services related to certain long-term contracts. Given the contract dayrates relative to market dayrates at the Effective Date, we determined the contracts represent favorable contract intangible assets. Based on a discounted cash flow analysis utilizing the dayrate differential between current market dayrates and the contract dayrates, and a risk-adjusted discount rate of 17%, we determined the aggregate fair value of our contracts for these certain contracts to be $113.4 million above the fair value of the contracts if they were priced at current market dayrates on the Effective Date. The dayrate differential on these contracts as compared to prior years was primarily driven by the combination of continued market oversupply of offshore drilling units, the volatility in oil and gas price and the unprecedented crude product consumption levels experienced in 2020. Debt The valuations of the Company’s Revolving Credit Facility and Second Lien Notes were based on relevant market data as of the Effective Date and the terms of each of the respective instruments. Considering the interest rates and implied yields for the Revolving Credit Facility and Second Lien Notes were within a range of comparable market yields (with considerations for term and seniority), fair value adjustments were recorded relating to each of the instruments. Successor Warrants On the Effective Date, the Company issued Tranche 1 Warrants and Tranche 2 Warrants to certain former bondholders as part of the settlement of their pre-petition Consolidated Balance Sheet at Emergence The adjustments set forth in the following Consolidated Balance Sheet as of February 5, 2021 reflect the consummation of the transactions contemplated by the Plan and carried out by the Company (“Reorganization Adjustments”) and the fair value adjustments as a result of the application of fresh start accounting (“Fresh Start Adjustments”). The explanatory notes provide additional information with regard to the adjustments recorded, the methods used to determine fair values and significant assumptions or inputs.

Acquisitions and Divestitures	Note 4—Acquisitions and Divestitures Proposed Business Combination with Maersk Drilling On November 10, 2021, Noble entered into a Business Combination Agreement (the “Business Combination Agreement”) with Noble Finco Limited, a private limited company formed under the laws of England and Wales and an indirect, wholly owned subsidiary of Noble (“Topco”), Noble Newco Sub Limited, a Cayman Islands exempted company and a direct, wholly owned subsidiary of Topco (“Merger Sub”), and The Drilling Company of 1972 A/S, a Danish public limited liability company (“Maersk Drilling”), pursuant to which, among other things, (i) (x) Noble will merge with and into Merger Sub (the “Maersk Drilling Merger”), with Merger Sub surviving the Maersk Drilling Merger as a wholly owned subsidiary of Topco, and (y) the Ordinary Shares will convert into an equivalent number of class A ordinary shares, par value $0.00001 per share, of Topco (the “Topco Shares”), and (ii) (x) Topco will make a voluntary tender exchange offer to Maersk Drilling’s shareholders as described below (the “Offer” and, together with the Maersk Drilling Merger and the other transactions contemplated by the Business Combination Agreement, the “Business Combination”) and (y) upon the consummation of the Offer, if more than 90% of the issued and outstanding shares of Maersk Drilling, nominal value Danish krone (“DKK”) 10 per share (“Maersk Drilling Shares”), are acquired by Topco, Topco will redeem any Maersk Drilling Shares not exchanged in the Offer by Topco for Topco Shares or cash, at the election of the holder (cash for holders that do not make an election), under Danish law by way of a compulsory purchase. The board of directors of Noble (the “Board”) and the board of directors of Maersk Drilling have unanimously approved and adopted the Business Combination Agreement. The Business Combination is subject to Noble shareholder approval, acceptance of the Offer by holders of at least 80% of Maersk Drilling Shares, merger clearance and other regulatory approvals, listing on the NYSE and Nasdaq Copenhagen and other customary conditions. Following the closing of the Business Combination, assuming all of the Maersk Drilling Shares are acquired by Topco through the Offer and no cash is paid by Topco in the Offer, Topco will own all of Noble’s and Maersk Drilling’s respective businesses and the former shareholders of Noble and former shareholders of Maersk Drilling will each own approximately 50% of the outstanding Topco Shares (or 50.8% and 49.2%, respectively, if Topco pays $50.0 million in the Offer). Topco will be renamed Noble Corporation Plc, will be a public limited company domiciled (tax resident) in the United Kingdom and will be headquartered in Houston, Texas. Topco is expected to have certain management functions relating to the holding of shares, financing, cash management, incentive compensation and other relevant holding company functions. In addition, the board of directors of the combined company (the “Topco Board”) will be comprised of seven individuals, including three individuals designated by Noble, three individuals designated by Maersk Drilling, and Robert W. Eifler, who will serve as the President and Chief Executive Officer of the combined company. Charles M. (Chuck) Sledge, the current Chairman of the Board, will become chairman of the Topco Board, and Claus V. Hemmingsen, the current Chairman of Maersk Drilling’s board of directors, will be one of the three directors designated by Maersk Drilling. Topco will apply to have Topco Shares listed on the New York Stock Exchange and on Nasdaq Copenhagen A/S. At the effective time of the Maersk Drilling Merger (the “Maersk Drilling Merger Effective Time”), subject to the terms and conditions set forth in the Business Combination Agreement, (i) each Ordinary Share of Noble issued and outstanding immediately prior to the Maersk Drilling Merger Effective Time will be converted into one newly and validly issued, fully paid and non-assessable Subject to the terms and conditions set forth in the Business Combination Agreement, following the approval of certain regulatory filings with the Danish Financial Supervisory Authority, Topco has agreed to commence the Offer to acquire up to 100% of the then outstanding Maersk Drilling Shares and voting rights of Maersk Drilling, not including any treasury shares held by Maersk Drilling. The Offer is conditioned upon, among other things, holders of at least 80% of the then outstanding Maersk Drilling Shares and voting rights of Maersk Drilling tendering their shares in the Offer (which percentage may be lowered by Topco in its sole discretion to not less than 70%) (the “Minimum Acceptance Condition”). In the Offer, Maersk Drilling shareholders may exchange each Maersk Drilling Share for 1.6137 newly and validly issued, fully paid and non-assessable of the Offer (the “Acceptance Time”) is converted, at the Acceptance Time, into the right to receive, on the same terms and conditions as were applicable under the Maersk Drilling RSU Long-Term Incentive Programme for Executive Management 2019 and the Maersk Drilling RSU Long-Term Incentive Programme 2019 (including any vesting conditions), that number of Topco Shares equal to the product of (1) the number of Maersk Drilling Shares subject to such Maersk Drilling RSU Award immediately prior to the Acceptance Time and (2) the Exchange Ratio, with any fractional Maersk Drilling Shares rounded to the nearest whole share. Upon conversion such Maersk Drilling RSU Awards will cease to represent a right to receive Maersk Drilling Shares (or value equivalent to Maersk Drilling Shares). The Business Combination Agreement contains customary warranties and covenants by Noble, Topco, Merger Sub and Maersk Drilling. The Business Combination Agreement also contains customary pre-closing Topco’s obligation to accept for payment or, subject to any applicable rules and regulations of Denmark, pay for any Maersk Drilling Shares that are validly tendered in the Offer and not validly withdrawn prior to the expiration of the Offer is subject to certain customary conditions, including, among others, that the Minimum Acceptance Condition shall have been satisfied. Maersk Drilling may require that Topco does not accept for payment or, subject to any applicable rules and regulations of Denmark, pay for the Maersk Drilling Shares that are validly tendered in the Offer and not validly withdrawn prior to the expiration of the Offer if certain customary conditions are not met. Subject to the satisfaction or waiver of the conditions set forth in the Business Combination Agreement, the Business Combination is expected to close in mid-2022. The Business Combination Agreement contains certain termination rights for both Noble and Maersk Drilling. Pacific Drilling Merger On April 15, 2021, Noble purchased Pacific Drilling Company LLC (“Pacific Drilling”), an international offshore drilling contractor, in an all-stock Purchase Price Allocation The transaction has been accounted for using the acquisition method of accounting under ASC Topic 805, Business Combinations, with Noble being treated as the accounting acquirer. Under the acquisition method of accounting, the assets and liabilities of Pacific Drilling and its subsidiaries have been recorded at their respective fair values as of the date of completion of the Pacific Drilling Merger and added to Noble’s. The preliminary purchase price assessment remains an ongoing process and is subject to change for up to one year subsequent to the closing date of the Pacific Drilling Merger. Determining the fair values of the assets and liabilities of Pacific Drilling and the consideration paid requires judgment and certain assumptions to be made, the most significant of these being related to the valuation of Pacific Drilling’s mobile offshore drilling units and other related tangible assets and the fair value of the Ordinary Shares issued by Noble. The valuation of the Pacific Drilling’s mobile offshore drilling units was determined by using a combination of (1) the discounted cash flows expected to be generated from the drilling assets over their remaining useful lives and (2) the cost to replace the drilling assets, as adjusted by the current market for similar offshore drilling assets. Assumptions used in our assessment included, but were not limited to, future marketability of each unit in light of the current market conditions and its current technical specifications, timing of future contract awards and expected operating dayrates, operating costs, utilization rates, tax rates, discount rate, capital expenditures, market values, weighting of market values, reactivation costs, estimated economic useful lives and, in certain cases, our belief that a drilling unit is no longer marketable and is unlikely to return to service in the near to medium term. We included an allocation for corporate overhead when calculating the discounted cash flows expected to be generated from our drilling assets over their remaining useful lives. The cash flows were discounted at our WACC, which was derived from a blend of our after-tax As Noble was not yet trading on the New York Stock Exchange at the time of the Pacific Drilling Merger, the valuation of our Ordinary Shares issued by Noble as consideration required an analysis of the discounted cash flows expected to be generated by the drilling assets of the combined entity. These discounted cash flows were derived utilizing many of the same types of assumptions as were used in the valuation of the Noble drilling assets at emergence as well the Pacific Drilling assets. In addition, the discounted cash flows of the combined entity considered annual cost saving synergies from the operation of the Noble and Pacific Drilling assets as a single fleet, and were accordingly discounted at a market participant WACC for the combined entity. Lastly, the valuation of the Ordinary Shares considered the fair value of debt, warrants and the management incentive plan of the combined entity to arrive at the fair value of common equity. The inputs and assumptions related to the value of Noble’s Ordinary Shares are also categorized as Level 3 in the fair value hierarchy. The Pacific Drilling Merger resulted in a gain on bargain purchase due to the estimated fair value of the identifiable net assets acquired exceeding the purchase consideration transferred by $62.3 million and is shown as a gain on bargain purchase on Noble’s consolidated statement of operations. Management reviewed the Pacific Drilling assets acquired and liabilities assumed as well as the assumptions utilized in estimating their fair values. An adjustment of $2.2 million to the valuation allowance on the deferred tax assets acquired in the Pacific Drilling Merger was recorded in the three months ended December 31, 2021. Upon completion of our assessment, the Company concluded that recording a gain on bargain purchase was appropriate and required under US GAAP. The bargain purchase was a result of a combination of factors, including a prolonged downturn in the drilling industry which led to challenging fundamentals for many competitors in the offshore drilling sector. The Company believes the seller was motivated to complete the transaction as the emerging market dynamics do not appear to be favorable to smaller rig fleets which operate across multiple regions. The following table represents the preliminary allocation of the total purchase price of Pacific Drilling to the identifiable assets acquired and the liabilities assumed based on the fair values as of the acquisition date.

Successor Period From February 6, 2021 through December 31, 2021 Revenue $ 792,999 Net income $ 69,966 Net income per share Basic $ 1.05 Diluted $ 0.98 The pro forma results include, among others, (i) a reduction in Pacific Drilling’s historically reported depreciation expense for adjustments to property and equipment and (ii) an adjustment to reflect the gain on bargain purchase as if the Pacific Drilling Merger had occurred on February 6, 2021. Sale of Rigs in Saudi Arabia On August 25, 2021, Finco and certain subsidiaries of the Company entered into a Purchase and Sale Agreement (the “Purchase and Sale Agreement”) to sell the jackup rigs operated by the Company in Saudi Arabia to ADES International Holding Limited (“ADES”) for a purchase price of $292.4 million in cash. Pursuant to the terms of the Purchase and Sale Agreement, the jackups, Noble Roger Lewis Noble Scott Marks Noble Joe Knight Noble Johnny Whitstine The Purchase and Sale Agreement also included certain covenants that the Company has agreed to not carry on or be engaged in the operation of jackup drilling rigs in the territorial waters of the Kingdom of Saudi Arabia in the Arabian Gulf for a term after the closing date of (i) one year for purposes of drilling gas wells and (ii) two years for the purposes of drilling oil wells.

During the years ended 2020 and 2019, we recognized a non-cash In preparation for Hurricane Ida in the US Gulf of Mexico, the Noble Globetrotter II Noble Globetrotter II occurrence and a $50.0 million annual limit; however, our insurance policies may not adequately cover our losses and related claims, which could adversely affect our business. Timing differences are likely to exist between the damage costs, capital expenditures made to repair or restore properties and recognition and receipt of insurance proceeds reflected in the Company’s financial statements. The Company assessed the damage sustained on the Noble Globetrotter II Noble Globetrotter II For the year ended December 31, 2020, we sold six rigs, which had a net book value of $17.1 million for total proceeds of $26.7 million, resulting in a gain of $8.9 million.

Loss on Impairment	Note 7— Loss on Impairment Asset Impairments Consistent with our accounting policies discussed in “Note 1— Organization and Significant Accounting Policies,” we evaluate our property and equipment for impairment whenever there are changes in facts which suggest that the value of the asset is not recoverable. For the period from January 1, 2021 through February 5, 2021 and the period from February 6, 2021 through December 31, 2021, we did not identify any impairment triggers for our property and equipment. During the first quarter of 2020, the pandemic and OPEC+ production level disagreements resulted in an unprecedented steep decline in the demand for oil and a substantial surplus of oil. We considered these events to be an impairment indicator and based on our assumptions and analysis, we impaired the carrying value of four floaters. For our impaired units, the carrying values were written down to scrap value and subsequently sold in late 2020. During the fourth quarter of 2020, the combination of the growing commitments by many of our customers to a transition to cleaner energy options, and the prolonged impacts of the pandemic, the continued oversupply of offshore drilling units placed further downward pressure on global oil demand and on our industry, potentially lengthening what was already expected to be a slow recovery. We considered these events to be an impairment indicator and based on our assumptions and analysis, we impaired the carrying value of three floaters and nine jackups. We estimated the fair values of these units using a weighting between an income valuation approach and a market approach, utilizing significant unobservable inputs, representative of a Level 3 fair value measurement. Assumptions used in our assessment included, but were not limited to, future marketability of each unit in light of the current market conditions and its current technical specifications, timing of future contract awards and expected operating dayrates, operating costs, utilization rates, discount rates, capital expenditures, market values, weighting of market values, reactivation costs, estimated economic useful lives and, in certain cases, our belief that a drilling unit is no longer marketable and is unlikely to return to service in the near to medium term. During the quarters ended March 31, 2020 and December 31, 2020, we recognized non-cash their corresponding estimated fair values. The impact of the current global economic turmoil on our customers’ and our business continues to be uncertain. During the year ended December 31, 2020, we recognized approximately $3.9 billion in impairment charges for seven floaters and nine jackups, and $24.0 million of impairment charges related to certain capital spare equipment. Based upon our impairment analysis, we impaired the carrying values to their corresponding estimated fair values for two , Noble Bully II

Debt	Note 8— Debt Post-emergence Debt Senior Secured Revolving Credit Facility On the Effective Date, Finco and Noble International Finance Company (“NIFCO”) entered into the Revolving Credit Agreement providing for the $675.0 million Revolving Credit Facility and cancelled all debt that existed immediately prior to the Effective Date. The Revolving Credit Facility matures on July 31, 2025. Subject to the satisfaction of certain conditions, Finco may from time to time designate one or more of Finco’s other wholly-owned subsidiaries as additional borrowers under the Revolving Credit Agreement (collectively with Finco and NIFCO, the “Borrowers”). As of the Effective Date, $177.5 million of loans were outstanding, and $8.8 million of letters of credit were issued, under the Revolving Credit Facility. As of December 31, 2021, we had no loans outstanding and $8.8 million of letters of credit issued under the Revolving Credit Facility and an additional $6.3 million in letters of credit and surety bonds issued under bilateral arrangements. All obligations of the Borrowers under the Revolving Credit Agreement, certain cash management obligations and certain swap obligations are unconditionally guaranteed, on a joint and several basis, by Finco and certain of its direct and indirect subsidiaries (collectively with the Borrowers, the “Credit Parties”), including a guarantee by each Borrower of the obligations of each other Borrower under the Revolving Credit Agreement. All such obligations, including the guarantees of the Revolving Credit Facility, are secured by senior priority liens on substantially all assets of, and the equity interests in, each Credit Party, subject to certain exceptions and limitations described in the Revolving Credit Agreement. Neither Pacific Drilling Company LLC nor any of its current subsidiaries is a subsidiary guarantor of the Revolving Credit Facility, and none of their assets secure the Revolving Credit Facility. In addition, none of the Maersk Drilling assets will secure the Revolving Credit Facility upon the closing of the Business Combination. The loans outstanding under the Revolving Credit Facility bear interest at a rate per annum equal to the applicable margin plus, at Finco’s option, either: (i) the reserve-adjusted LIBOR or (ii) a base rate, determined as the greatest of (x) the prime loan rate as published in the Wall Street Journal, (y) the federal funds effective rate plus 1/2 of 1%, and (z) the reserve-adjusted one-month The Borrowers are required to pay customary quarterly commitment fees and letter of credit and fronting fees. Availability of borrowings under the Revolving Credit Agreement is subject to the satisfaction of certain conditions, including restrictions on borrowings if, after giving effect to any such borrowings and the application of the proceeds thereof, (i) the aggregate amount of Available Cash (as defined in the Revolving Credit Agreement) would exceed $100.0 million, (ii) the Consolidated First Lien Net Leverage Ratio (as defined in the Revolving Credit Agreement) would be greater than 5.50 to 1.00 and the aggregate principal amount outstanding under the Revolving Credit Facility would exceed $610.0 million, or (iii) the Asset Coverage Ratio (as described below) would be less than 2.00 to 1.00. Mandatory prepayments and, under certain circumstances, commitment reductions are required under the Revolving Credit Facility in connection with (i) certain asset sales, asset swaps and events of loss (subject to reinvestment rights if no event of default exists) and (ii) certain debt issuances. Available Cash in excess of $150.0 million is also required to be applied periodically to prepay loans (without a commitment reduction). The loans under the Revolving Credit Facility may be voluntarily prepaid, and the commitments thereunder voluntarily terminated or reduced, by the Borrowers at any time without premium or penalty, other than customary breakage costs. The Revolving Credit Agreement obligates Finco and its restricted subsidiaries to comply with the following financial maintenance covenants: • as of December 31, 2021, Adjusted EBITDA (as defined in the Revolving Credit Agreement) is not permitted to be lower than $25.0 million for the four fiscal quarter periods ending on December 31, 2021; • as of the last day of each fiscal quarter ending on or after March 31, 2022, the ratio of Adjusted EBITDA to Cash Interest Expense (as defined in the Revolving Credit Agreement) is not permitted to be less than (i) 2.00 to 1.00 for each four fiscal quarter period ending on or after March 31, 2022 until June 30, 2024, and (ii) 2.25 to 1.00 for each four fiscal quarter period ending thereafter; and • for each fiscal quarter ending on or after June 30, 2021, the ratio of (i) Asset Coverage Aggregate Rig Value (as defined in the Revolving Credit Agreement) to (ii) the aggregate principal amount of loans and letters of credit outstanding under the Revolving Credit Facility (the “Asset Coverage Ratio”) as of the last day of any such fiscal quarter is not permitted to be less than 2.00 to 1.00. The Revolving Credit Facility contains affirmative and negative covenants, representations and warranties and events of default that the Company considers customary for facilities of this type. Second Lien Notes Indenture On the Effective Date, pursuant to the Backstop Commitment Agreement and in accordance with the Plan, Noble and Finco consummated the Rights Offering of Second Lien Notes and associated Ordinary Shares at an aggregate subscription price of $200.0 million. An aggregate principal amount of $216.0 million of Second Lien Notes was issued in the Rights Offering, which includes the aggregate subscription price of $200.0 million plus a backstop fee of $16.0 million which was paid in kind. The Second Lien Notes mature on February 15, 2028. The Second Lien Notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured second-priority basis, by the direct and indirect subsidiaries of Finco that are Credit Parties under the Revolving Credit Facility. Neither Pacific Drilling Company LLC nor any of its current subsidiaries is a subsidiary guarantor of the Second Lien Notes, and none of their assets secure the Second Lien Notes. In addition, none of the Maersk Drilling assets will secure the Second Lien Notes upon the closing of the Business Combination. The Second Lien Notes and such guarantees are secured by senior priority liens on the assets subject to liens securing the Revolving Credit Facility, including the equity interests in Finco and each guarantor of the Second Lien Notes, all of the rigs owned by the Company as of the Effective Date or acquired thereafter, certain assets related thereto, and substantially all other assets of Finco and such guarantors, in each case, subject to certain exceptions and limitations. Such collateral does not include any assets of, or equity interests in, Pacific Drilling or any of its current subsidiaries. Interest on the Second Lien Notes accrues, at Finco’s option, at a rate of: (i) 11% per annum, payable in cash; (ii) 13% per annum, with 50% of such interest to be payable in cash and 50% of such interest to be payable by issuing additional Second Lien Notes (“PIK Notes”); or (iii) 15% per annum, with the entirety of such interest to be payable by issuing PIK Notes. Finco shall pay interest semi-annually in arrears on February 15 and August 15 of each year, commencing August 15, 2021. For accrual purposes, we have assumed we will make the next interest payment in cash and have accrued at a rate of 11%; however, the actual interest election will be made no later than the record date for such interest payment. On or after February 15, 2024, Finco may redeem all or part of the Second Lien Notes at fixed redemption prices (expressed as percentages of the principal amount), plus accrued and unpaid interest, if any, to, but excluding, the redemption date. Finco may also redeem the Second Lien Notes, in whole or in part, at any time and from time to time on or before February 14, 2024 at a redemption price equal to 106% of the principal amount plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date, plus a “make-whole” premium. Notwithstanding the foregoing, if a Change of Control (as defined in the Second Lien Notes Indenture) occurs prior to (but not including) February 15, 2024, then, within 120 days of such Change of Control, Finco may elect to purchase all remaining outstanding Second Lien Notes at a redemption price equal to 106% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. The Second Lien Notes contain covenants and events of default that the Company considers customary for notes of this type. Pre-emergence 2017 Credit Facility In December 2017, Noble Cayman Limited, a Cayman Islands company and a wholly-owned indirect subsidiary of Finco; Noble International Finance Company, a Cayman Islands company and a wholly-owned indirect subsidiary of Finco; and Noble Holding UK Limited, a company incorporated under the laws of England and Wales and a wholly-owned direct subsidiary of Legacy Noble (“NHUK”), as parent guarantor, entered into a senior unsecured credit agreement (as amended, the “2017 Credit Facility”). In July 2019, we executed a first amendment to our 2017 Credit Facility, which, among other things, reduced the maximum aggregate amount of commitments thereunder from $1.5 billion to $1.3 billion. Prior to the filing of the Chapter 11 Cases, the 2017 Credit Facility was scheduled to mature in January 2023. Borrowings were available for working capital and other general corporate purposes. The 2017 Credit Facility provided for a letter of credit sub-facility In April 2020, we borrowed $100.0 million under the 2017 Credit Facility to pay down our indebtedness under the Seller Loans (as defined herein) as further described below. At December 31, 2020, we had $545.0 million of borrowings outstanding under the 2017 Credit Facility. At December 31, 2020, we had $8.8 million of letters of credit issued under the 2017 Credit Facility and an additional $6.0 million in letters of credit and surety bonds issued under unsecured or cash collateralized bilateral arrangements. The filing of the Chapter 11 Cases constituted events of default that accelerated the Company’s obligations under the indentures governing our outstanding senior notes and under our 2017 Credit Facility. In addition, the unpaid principal and interest due under our indentures and the 2017 Credit Facility became immediately due and payable. However, any efforts to enforce such payment obligations with respect to our senior notes and 2017 Credit Facility were automatically stayed as a result of the filing of the Chapter 11 Cases, and the creditors’ rights of enforcement were subject to the applicable provisions of the Bankruptcy Code. See “Note 1— Organization and Basis of Presentation” for additional information. The Company had $545.0 million outstanding under the 2017 Credit Facility prior to the Effective Date. On the Effective Date, all outstanding obligations under the 2017 Credit Facility were terminated and the holders of claims under the 2017 Credit Facility had such obligations repaid using cash on hand, repaid using proceeds from the Rights Offering, or refinanced through the Revolving Credit Facility. On the Effective Date, all liens and security interests granted to secure such obligations were terminated and are of no further force and effect. 2015 Credit Facility Effective January 2018, in connection with entering into the 2017 Credit Facility, we amended our $300.0 million senior unsecured credit facility that would have matured in January 2020 and was guaranteed by our indirect, wholly-owned subsidiaries, Noble Holding (US) LLC and Noble Holding International Limited (“NHIL”), a finance subsidiary of Finco, (as amended, the “2015 Credit Facility”). As a result of the 2015 Credit Facility’s reduction in the aggregate principal amount of commitments, we recognized a net loss of approximately $2.3 million in the year ended December 31, 2018. On December 20, 2019, we repaid $300.0 million of outstanding borrowings and terminated the 2015 Credit Facility. Seller Loans In February 2019, we purchased the Noble Joe Knight paid-in-kind in-kind paid-in-kind In September 2018, we purchased the Noble Johnny Whitstine paid-in-kind paid-in-kind paid-in-kind Both of the Seller Loans were guaranteed by Finco and each was secured by a mortgage on the applicable rig and by the pledge of the shares of the applicable single-purpose entity that owned the relevant rig. Each Seller Loan contained a debt to total capitalization ratio requirement that such ratio not exceed 0.55 at the end of each fiscal quarter, a $300.0 million minimum liquidity financial covenant and an asset and revenue covenant substantially similar to the Guaranteed Notes, as well as other covenants and provisions customarily found in secured transactions, including a cross-default provision. Each Seller Loan required immediate repayment on the occurrence of certain events, including the termination of the drilling contract associated with the relevant rig or circumstances in connection with a material adverse effect. In April 2020, the Company agreed with the lender under the Seller Loans to pay off 85% of the outstanding principal amount of the Seller Loans in exchange for a discount to the outstanding loan balance. On April 20, 2020, the Company made a payment of $48.1 million under the 2019 Seller Loan and $53.6 million under the 2018 Seller Loan, and, upon the lender’s receipt of such payment, interest ceased accruing, and the financial covenants set forth in the agreements relating to the Seller Loans ceased to apply. On July 20, 2020, at the conclusion of the 90-day As a result of the early repayment of the Seller Loans and the conclusion of the 90-day Senior Notes In March 2019, we completed cash tender offers for our Senior Notes due 2020, Senior Notes due 2021, Senior Notes due 2022 and Senior Notes due 2024. Pursuant to such tender offers, we purchased $440.9 million aggregate principal amount of these senior notes for $400.0 million, plus accrued interest, using cash on hand and borrowings under the 2015 Credit Facility. As a result of these transactions, we recognized a net gain of approximately $31.3 million. On the Effective Date, in accordance with the Plan, all outstanding obligations under our senior notes were cancelled and the indentures governing such obligations were cancelled, except to the limited extent expressly set forth in the Plan. See “Note 2— Chapter 11 Emergence” for additional information. Fair Value of Debt Fair value represents the amount at which an instrument could be exchanged in a current transaction between willing parties. The estimated fair value of our debt instruments was based on the quoted market prices for similar issues or on the current rates offered to us for debt of similar remaining maturities (Level 2 measurement). The carrying amount of the Revolving Credit Facility approximates fair value as the interest rate is variable and reflective of market rates. All remaining fair value disclosures are presented in “Note 15— Fair Value of Financial Instruments.” The following table presents the carrying value, net of unamortized debt issuance costs and discounts or premiums, and the estimated fair value of our total debt, not including the effect of unamortized debt issuance costs, respectively: Successor Predecessor (1) Carrying Value Estimated Fair Carrying Value Estimated Fair Senior secured notes 11.000% Senior Notes due February 2028 $ 216,000 $ 236,792 $ — $ — Senior unsecured notes 4.900% Senior Notes due August 2020 $ — $ — $ 62,535 $ 1,366 4.625% Senior Notes due March 2021 — — 79,936 1,596 3.950% Senior Notes due March 2022 — — 21,213 354 7.750% Senior Notes due January 2024 — — 397,025 7,925 7.950% Senior Notes due April 2025 — — 450,000 8,348 7.875% Senior Notes due February 2026 — — 750,000 301,935 6.200% Senior Notes due August 2040 — — 393,596 7,966 6.050% Senior Notes due March 2041 — — 395,002 7,327 5.250% Senior Notes due March 2042 — — 483,619 9,701 8.950% Senior Notes due April 2045 — — 400,000 7,420 Credit facility: Senior Secured Revolving Credit Facility matures July 2025 — — — — 2017 Credit Facility due to mature January 2023 — — 545,000 545,000 Total debt 216,000 236,792 3,977,926 898,938 Less: Current maturities of long-term debt — — — — Long-term debt $ 216,000 $ 236,792 $ — $ — (1) Includes write-off As discussed in “Note 1— Organization and Basis of Presentation,” from the Petition Date until the Effective Date, the Company operated as a debtor-in-possession On the Effective Date, in accordance with the Plan, all outstanding obligations under our senior notes were cancelled and the indentures governing such obligations were cancelled, except to the limited extent expressly set forth in the Plan.

Equity	Note 9— Equity Share Capital As of December 31, 2021, Noble had approximately 60.2 million shares outstanding and trading. As of December 31, 2020, Legacy Noble had approximately 251.1 million shares outstanding and trading. At Legacy Noble’s 2020 Annual General Meeting, Legacy Noble’s shareholders authorized its Board of Directors to increase share capital through the issuance of up to approximately 8.7 million ordinary shares (at then current nominal value of $0.01 per share). That authority to allot shares has expired on the Effective Date. Other than shares issued to Legacy Noble’s directors under the Noble Corporation 2017 Director Omnibus Plan, the authority was not used to allot shares during the period from January 1, 2021 through February 5, 2021 or the period from February 6, 2021 through December 31, 2021. Pursuant to the Memorandum of Association of Noble Corporation, the share capital of Noble is $6,000 divided into 500,000,000 ordinary shares of a par value of $0.00001 each and 100,000,000 shares of a par value of $0.00001, each of such class or classes having the rights as the Board may determine from time to time. The payment of future dividends will depend on our results of operations, financial condition, cash requirements, future business prospects, contractual and indenture restrictions and other factors deemed relevant by our current Board of Directors. In accordance with the Plan, all agreements, instruments and other documents evidencing, relating to or otherwise connected with any of Legacy Noble’s equity interests outstanding prior to the Effective Date, including all equity-based awards, were cancelled and all such equity interests have no further force or effect after the Effective Date. Pursuant to the Plan, the holders of Legacy Noble’s ordinary shares, par value $0.01 per share, outstanding prior to the Effective Date received their pro rata share of the Tranche 3 Warrants to acquire Ordinary Shares. Warrants At December 31, 2021, we had outstanding 8.3 million Tranche 1 Warrants, 8.3 million Tranche 2 Warrants and 2.8 million Tranche 3 Warrants. The Tranche 1 Warrants are exercisable for one Ordinary Share per warrant at an exercise price of $19.27 per warrant, the Tranche 2 Warrants are exercisable for one Ordinary Share per warrant at an exercise price of $23.13 per warrant and the Tranche 3 Warrants are exercisable for one Ordinary Share per warrant at an exercise price of $124.40 per warrant (in each case as may be adjusted from time to time pursuant to the applicable warrant agreement). The Tranche 1 Warrants and the Tranche 2 Warrants are exercisable until 5:00 p.m., Eastern time, on February 4, 2028 and the Tranche 3 Warrants are exercisable until 5:00 p.m., Eastern time, on February 4, 2026. The Tranche 1 Warrants and the Tranche 2 Warrants have Black-Scholes protections, including in the event of a Fundamental Transaction (as defined in the applicable warrant agreement). The Tranche 1 Warrants and the Tranche 2 Warrants also provide that while the Mandatory Exercise Condition (as defined in the applicable warrant agreement) set forth in the applicable warrant agreement has occurred and is continuing, Noble or the holders of Tranche 1 Warrants or Tranche 2 Warrants representing at least 20% of such tranche (the “Required Mandatory Exercise Warrantholders”) have the right and option (but not the obligation) to cause all or a portion of the warrants to be exercised on a cashless basis. In the case of Noble, under the Mandatory Exercise Condition, all of the Tranche 1 Warrants or the Tranche 2 Warrants (as applicable) would be exercised. In the case of the electing Required Mandatory Exercise Warrantholders, under the Mandatory Exercise Condition, all of their respective Tranche 1 Warrants or Tranche 2 Warrants (as applicable) would be exercised. Mandatory exercises entitle the holder of each warrant subject thereto to (i) the number of Ordinary Shares issuable upon exercise of such warrant on a cashless basis and (ii) an amount payable in cash, Ordinary Shares or a combination thereof (in Noble’s sole discretion) equal to the Black-Scholes Value (as defined in the applicable warrant agreement) with respect to the number of Ordinary Shares withheld upon exercise of such warrant on a cashless basis. At December 31, 2021, the Mandatory Exercise Condition set forth in the warrant agreements for the Tranche 1 Warrants and the Tranche 2 Warrants was not satisfied. Successor Share-Based Compensation Plans Stock Plans On February 18, 2021, the Company adopted the long-term incentive plan (the “Noble Incentive Plan”), which permits grants of options, stock appreciation rights, stock or stock unit awards or cash awards, any of which may be structured as a performance award, from time to time to employees and non-employee non-employee Restricted Stock Units (“RSUs”) We have awarded both Time Vested RSUs (“TVRSUs”) and Performance Vested RSUs (“PVRSUs”) under the Noble Incentive Plan. The TVRSUs generally vest over a three-year period. The number of PVRSUs which vest will depend on the degree of achievement of specified corporate performance criteria over a three-year performance period. These criteria consist of market and performance based criteria. The TVRSUs are valued on the date of award at our underlying share price. The total compensation for units that ultimately vest is recognized over the service period. The shares and related nominal value are recorded when the RSU vests and additional paid-in In 2021, 40 percent of the TVRSUs granted to non-employee The market-based PVRSUs are valued on the date of grant based on the estimated fair value. Estimated fair value is determined based on numerous assumptions, including an estimate of the likelihood that our stock price performance will achieve the targeted thresholds and the expected forfeiture rate. The fair value is calculated using a Monte Carlo Simulation Model. The assumptions used to value the PVRSUs include historical volatility and risk-free interest rates over a time period commensurate with the remaining term prior to vesting, as follows for the respective grant dates: February 19, 2021 October 1, 2021 December 1, 2021 Valuation assumptions: Expected volatility 50.0 % 92.2 % 95.1 % Expected dividend yield — % — % — % Risk-free interest rate 0.19 % 0.33 % 0.58 % Additionally, similar assumptions were made for each of the companies included in the defined index and the peer group of companies in order to simulate the future outcome using the Monte Carlo Simulation Model. A summary of the RSUs awarded for the period from February 6, 2021 through December 31, 2021 is as follows: 2021 Equity-classified TVRSU Units awarded 1,735,843 Weighted-average share price at award date $ 16.68 Weighted-average vesting period (years) 2.94 Liability-classified TVRSU Units awarded 52,364 Weighted-average share price at award date $ 16.76 Weighted-average vesting period (years) 2.81 PVRSU Units awarded 1,457,842 Weighted-average share price at award date $ 16.74 Three-year performance period ended December 31 2023 Weighted-average award date fair value $ 20.82 During the period from February 6, 2021 through December 31, 2021, we awarded 78,546 shares equity-classified TVRSUs and 52,364 shares liability-classified TVRSUs to our non-employee A summary of the status of non-vested Equity-Classified TVRSUs Weighted Award-Date PVRSUs (1) Weighted Award-Date Non-vested — $ — — $ — Awarded 1,735,843 16.68 1,457,842 20.82 Vested — — — — Forfeited (66,081 ) 16.44 — — Non-vested 1,669,762 $ 16.69 1,457,842 $ 20.82 (1) For awards granted during 2021, the number of PVRSUs shown equals the shares that would vest if the “target” level of performance is achieved. The minimum number of units is zero and the “maximum” level of performance is 200 percent of the amounts shown. During the period from February 6, 2021 through December 31, 2021, we granted 52,364 liability-classified TVRSUs at a weighted-average grant date fair value of $16.76, no units were vested during the period and no units were forfeited during the period. At December 31, 2021, we had 52,364 liability-classified TVRSUs outstanding with an associated total liability of $414.4 thousand. At December 31, 2021, there was $20.1 million of total unrecognized compensation cost related to the equity-classified TVRSUs, to be recognized over a remaining weighted-average period of 2.09 years. At December 31, 2021, there was $0.9 million of total unrecognized compensation cost related to the liability-classified TVRSUs, to be recognized over a remaining weighted-average period of 1.97 years. At December 31, 2021, there was $22.1 million of total unrecognized compensation cost related to the PVRSUs, to be recognized over a remaining weighted-average period of 2.00 years. The total potential compensation for PVRSUs is recognized over the service period regardless of whether the performance thresholds are ultimately achieved. Share-based amortization recognized during for the period from February 6, 2021 through December 31, 2021 related to all restricted stock totaled $16.5 million ($16.4 million net of income tax). During the period from February 6, 2021 through December 31, 2021, there was no capitalized share-based amortization. Predecessor Share-Based Compensation Plans All outstanding shares and equity awards of Legacy Noble were cancelled as a result of the Chapter 11 Cases. Stock Plans During 2015, Legacy Noble shareholders approved a new equity plan, the Noble Corporation plc 2015 Omnibus Incentive Plan (the “Legacy Noble Incentive Plan”), which permitted grants of options, stock appreciation rights, stock or stock unit awards or cash awards, any of which could be structured as a performance award, from time to time to employees who were to be granted awards under the Legacy Noble Incentive Plan. Neither consultants nor non-employee During 2020 and 2019, the Legacy Noble Incentive Plan was restated and Legacy Noble shareholders approved amendments, primarily to increase the number of Legacy Noble ordinary shares available for issuance as long-term incentive compensation under the Legacy Noble Incentive Plan by 8.7 million, 5.8 million and 5.0 million shares, respectively. The maximum aggregate number of Legacy Noble ordinary shares that could be granted for any and all awards under the Legacy Noble Incentive Plan could not exceed 40.0 million shares. During 2017, upon Legacy Noble shareholder approval, the Noble Corporation 2017 Director Omnibus Plan (the “Legacy Noble Director Plan”) replaced the previous plans that were terminated. Legacy equity awards to our non-employee During 2019, Legacy Noble shareholders approved amendments to increase the number of Legacy Noble ordinary shares available for issuance under the Legacy Noble Director Plan by 0.9 million shares, bringing the maximum aggregate number of Legacy Noble ordinary shares that could be granted for any and all awards under the Legacy Noble Director Plan to 1.8 million shares. Stock Options Options had a term of 10 February 5, 2021 December 31, 2020 December 31, 2019 Number of Weighted Number of Weighted Number of Weighted Outstanding at beginning of period 556,155 $ 30.39 708,400 $ 30.90 1,103,242 $ 28.74 Expired or cancelled (556,155 ) 30.39 (152,245 ) 32.78 (394,842 ) 24.85 Outstanding at end of period — — 556,155 30.39 708,400 30.90 Exercisable at end of period — $ — 556,155 $ 30.39 708,400 $ 30.90 All outstanding options were cancelled as a result of the Chapter 11 Cases and there were no stock options outstanding at December 31, 2021. The fair value of each option was estimated on the date of grant using a Black-Scholes pricing model. The expected term of options granted represented the period of time that the options were expected to be outstanding and was derived from historical exercise behavior, then current trends and values derived from lattice-based models. Expected volatilities were based on implied volatilities of traded options on our shares, historical volatility of our shares, and other factors. The expected dividend yield was based on historical yields on the date of grant. The risk-free rate was based on the US Treasury yield curve in effect at the time of grant. There were no non-vested Restricted Stock Units We awarded both TVRSUs and PVRSUs under the Legacy Noble Incentive Plan. The TVRSUs generally vested over a three-year period. The number of PVRSUs which would vest depended on the degree of achievement of specified corporate performance criteria over a three-year performance period. Depending on the date the PVRSU was awarded, these criteria consisted of market based criteria or market and performance based criteria. The TVRSUs were valued on the date of award at our underlying share price. The total compensation for units that ultimately vested was recognized over the service period. The shares and related nominal value were recorded when the RSUs vested and additional paid-in The market-based PVRSUs were valued on the date of grant based on the estimated fair value. Estimated fair value was determined based on numerous assumptions, including an estimate of the likelihood that our stock price performance would achieve the targeted thresholds and the expected forfeiture rate. The fair value was calculated using a Monte Carlo Simulation Model. The assumptions used to value the PVRSUs included historical volatility and risk-free interest rates over a time period commensurate with the remaining term prior to vesting, as follows: 2020 2019 Valuation assumptions: Expected volatility 69.8 % 59.6 % Expected dividend yield — % — % Risk-free interest rate 1.40 % 2.50 % Additionally, similar assumptions were made for each of the companies included in the defined index and the peer group of companies in order to simulate the future outcome using the Monte Carlo Simulation Model. A summary of the RSUs awarded for each of the years ended 2020 and 2019 is as follows: 2020 2019 TVRSU Units awarded 5,559,678 4,639,119 Weighted-average share price at award date $ 0.82 $ 3.02 Weighted-average vesting period (years) 3.0 3.0 PVRSU Units awarded 2,696,774 1,623,399 Weighted-average share price at award date $ 0.91 $ 3.13 Three-year performance period ended December 31 2022 2021 Weighted-average award date fair value $ 1.14 $ 3.61 There were no RSUs granted during the period from January 1, 2021 through February 5, 2021.

Revenue and Customers	Note 11— Revenue and Customers Contract Balances Accounts receivable are recognized when the right to consideration becomes unconditional based upon contractual billing schedules. Payment terms on invoiced amounts are typically 30 days. Current contract asset and liability balances are included in “Prepaid expenses and other current assets” and “Other current liabilities,” respectively, and noncurrent contract assets and liabilities are included in “Other assets” and “Other liabilities,” respectively, on our Consolidated Balance Sheets. The following table provides information about contract assets and contract liabilities from contracts with customers: Successor Predecessor Current contract assets $ 5,744 $ 10,687 Noncurrent contract assets — 3,174 Total contract assets 5,744 13,861 Current contract liabilities (deferred revenue) (18,403 ) (34,990 ) Noncurrent contract liabilities (deferred revenue) (9,352 ) (24,896 ) Total contract liabilities $ (27,755 ) $ (59,886 ) Significant changes in the remaining performance obligation contract assets and the contract liabilities balances during the period from February 6, 2021 to December 31, 2021, the period from January 1 through February 5, 2021 and the year ended December 31, 2020. are as follows: Contract Contract Net balance at December 31, 2019 (Predecessor) $ 30,800 $ (65,055 ) Amortization of deferred costs (27,043 ) — Additions to deferred costs 10,104 — Amortization of deferred revenue — 57,915 Additions to deferred revenue — (52,746 ) Total (16,939 ) 5,169 Net balance at December 31, 2020 (Predecessor) $ 13,861 $ (59,886 ) Amortization of deferred costs (1,607 ) — Additions to deferred costs 432 — Amortization of deferred revenue — 4,142 Additions to deferred revenue — (25,479 ) Fresh start accounting revaluation (12,686 ) 72,936 Total (13,861 ) 51,599 Net balance at 2/5/21 (Predecessor) $ — $ (8,287 ) Net balance at 2/6/21 (Successor) $ — $ (8,287 ) Amortization of deferred costs (3,908 ) — Additions to deferred costs 9,652 — Amortization of deferred revenue — 13,729 Additions to deferred revenue — (33,197 ) Total 5,744 (19,468 ) Net balance at 12/31/2021 (Successor) $ 5,744 $ (27,755 ) Contract Costs Certain direct and incremental costs incurred for upfront preparation, initial rig mobilization and modifications are costs of fulfilling a contract and are recoverable. These recoverable costs are deferred and amortized ratably to contract drilling expense as services are rendered over the initial term of the related drilling contract. Certain of our contracts include capital rig enhancements used to satisfy our performance obligations. These capital items are capitalized and depreciated in accordance with our existing property and equipment accounting policy. Costs incurred for the demobilization of rigs at contract completion are recognized as incurred during the demobilization process. Costs incurred for rig modifications or upgrades required for a contract, which are considered to be capital improvements, are capitalized as drilling and other property and equipment and depreciated over the estimated useful life of the improvement. Customer Contract Intangible Assets Upon emergence from the Chapter 11 Cases, the Company recognized a fair value adjustment of $113.4 million related to intangible assets for certain favorable customer contracts. These intangible assets will be amortized as a reduction of contract drilling services revenue from the Effective Date through the remainder of the contracts, approximately 18 months and 32 months, respectively. As of December 31, 2021, the net carrying amount was $61.8 million, $113.4 million gross less $51.5 million accumulated amortization. The expected remaining amortization is as follows: $43.5 million and $18.4 million for the years ending December 31, 2022 and 2023, respectively. We assess the recoverability of the unamortized balance when indicators of impairment are present. Should the review indicate that the carrying value is not fully recoverable, the portion not fully recoverable would be recognized as an impairment loss. We considered the events surrounding Hurricane Ida and the Noble Globetrotter II Future Amortization of Deferred Revenue The following table reflects revenue expected to be recognized in the future related to deferred revenue, by rig type, at the end of the reporting period: Year Ending December 31, 2022 2023 2024 2025 2026 and Total Floaters $ 11,930 $ 9,323 $ 29 $ — $ — $ 21,282 Jackups 6,473 — — — — 6,473 Total $ 18,403 $ 9,323 $ 29 $ — $ — $ 27,755 The revenue included above consists of expected mobilization, demobilization, and upgrade revenue for unsatisfied performance obligations. The amounts are derived from the specific terms within drilling contracts that contain such provisions, and the expected timing for recognition of such revenue is based on the estimated start date and duration of each respective contract based on information known at December 31, 2021. The actual timing of recognition of such amounts may vary due to factors outside of our control. We have taken the optional exemption, permitted by accounting standards, to exclude disclosure of the estimated transaction price related to the variable portion of unsatisfied performance obligations at the end of the reporting period, as our transaction price is based on a single performance obligation consisting of a series of distinct hourly, or more frequent, periods, the variability of which will be resolved at the time of the future services.

Income Taxes	Note 13— Income Taxes Legacy Noble is a tax resident in the UK and, as such, is subject to UK corporation tax on its taxable profits and gains. Noble is incorporated in the Cayman Islands and therefore not subject to tax in any jurisdiction. With respect to Legacy Noble, a UK tax exemption is available in respect of qualifying dividends income and capital gains related to the sale of qualifying participations.

If a portion or all of the December 31, 2021 reserves are not realized, the provision for income taxes could be reduced by up to $53.6 million. At December 31, 2020, the reserves for uncertain tax positions totaled $42.5 million. It is reasonably possible that our existing liabilities related to our reserve for uncertain tax positions may fluctuate in the next 12 months primarily due to the completion of open audits or the expiration of statutes of limitation. We include, as a component of our “Income tax benefit (provision),” potential interest and penalties related to recognized tax contingencies within our global operations. Interest and penalties resulted in an income tax expense of $6.7 million and $0.1 million for the period from February 6, 2021 to December 31, 2021 and for the period from January 1 through February 5, 2021, respectively. Interest and penalties resulted in an income tax benefit of $24.1 million in 2020 and $3.0 million in 2019. We recorded an income tax expense of $0.4 million and $3.4 million and income tax benefit $260.4 million during the period from February 6, 2021 to December 31, 2021, the period from January 1 through February 5, 2021 and the year ended December 31, 2020, respectively. During the period from February 6, 2021 to December 31, 2021, our tax provision included tax benefits of $24.3 million related to US and non-US non-US non-US During the period from January 1 through February 5, 2021, our income tax provision included a tax benefit of $1.7 million related to non-US During the year ended December 31, 2020, our tax benefit included the tax effect from asset impairments of $99.7 million, the tax impact of the application of the CARES Act of $39.0 million, a non-US return-to-provision non-US Our gross deferred tax asset balance at year-end write-off During the period ending December 31, 2021, we recognized deferred tax benefits of $22.8 million out of the total available tax benefits of $1.8 billion related to tax attributes available in Switzerland and Luxembourg. The available tax benefits in Switzerland are related to transition attributes created by a tax ruling we obtained in December 2021. These tax benefits are scheduled to expire by 2036. The available tax benefits in Luxembourg are related to net operating losses generated in years prior to 2021 by Pacific Drilling. Most of these tax losses are scheduled to expire between 2035 and 2038; however, a portion of the tax losses has no expiration date. In deriving the $22.8 million in tax benefits being recognized, we relied on sources of income attributable to the reversal of taxable temporary differences in the same periods as the relevant tax attributes and projected taxable income for the period covered by our relevant existing drilling contracts. Given the mobile nature of our assets, we are not able to reasonably forecast the jurisdiction of our taxable income from future drilling contracts. We also have limited objective positive evidence in historical periods for Switzerland and Luxembourg. Accordingly, in determining the amount of deferred tax benefits to recognize related to our Switzerland and Luxembourg rig-owning We conduct business globally and, as a result, we file numerous income tax returns in the US and in non-US non-US Legacy Noble conducted substantially all of its business through Finco and its subsidiaries in the pre-emergence pre-emergence non-UK pre-emergence Successor Predecessor Period From Period From Year Ended Year Ended Effect of: Tax rates which are different than the Cayman Islands (Successor) and UK (Predecessor) rates 22.6 % 0.5 % 0.4 % 4.3 % Tax impact of asset impairment and disposition — % — % 4.5 % 0.3 % Tax impact of restructuring — % 1.0 % 2.1 % (4.1 )% Tax impact of the tax regulation change — % — % 0.9 % — % Tax impact of valuation allowance (25.2 )% — % (4.3 )% 0.5 % Resolution of (reserve for) tax authority audits 2.9 % (0.2 )% 2.5 % 3.2 % Total 0.3 % 1.3 % 6.1 % 4.2 % At December 31, 2021, the Company asserts that its unremitted earnings and/or book/tax outside basis differences in certain of its subsidiaries are either permanently reinvested or are not expected to result in a material taxable event in the foreseeable future. Therefore, no material deferred taxes have been recorded related to such earnings and/or investments. Certain of the restructuring transactions effected by the Company in connection with the Plan have a material impact on the Company. For example, cancellation of indebtedness income from such restructuring transaction has significantly reduced the Company’s US tax attributes, including but not limited to NOL carryforwards. Further, the Plan was approved by the Bankruptcy Court on November 20, 2020. As a result, on the Effective Date, the Company experienced an ownership change under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), which subjects certain remaining tax attributes to an annual limitation under Section 382 of the Code.

The RP 2021, 2020 and 2019 mortality tables represent the new standard for defined benefit mortality assumptions due to adjusted life expectancies. The adoption of the updated mortality tables and the mortality improvement scales increased our pension liability on our US plans by approximately $0.7 million as of December 31, 2021 and decreased our pension liability by approximately $1.7 million and $2.1 million as of December 31, 2020 and 2019. During the fourth quarter of 2018, the UK High Court made a judgement confirming that UK pension schemes are required to equalize male and female members’ benefits for the effect of guaranteed minimum pensions (GMP). We have accounted for the impact of the GMP equalization as a plan amendment to our non-US Defined Benefit Plans—Disaggregated Plan Information Disaggregated information regarding our non-US Successor Predecessor 2021 2020 Non-US US Non-US US Projected benefit obligation $ 63,066 $ 243,538 $ 67,943 $ 266,090 Accumulated benefit obligation 63,066 243,538 67,943 266,090 Fair value of plan assets 78,465 226,830 83,808 222,417 The following table provides information related to those plans in which the PBO exceeded the fair value of the plan assets at December 31, 2021 and 2020. The PBO is the actuarially computed present value of earned benefits based on service to date and includes the estimated effect of any future salary increases.

The following table provides information related to those plans in which the accumulated benefit obligation (“ABO”) exceeded the fair value of plan assets at December 31, 2021 and 2020. The ABO is the actuarially computed present value of earned benefits based on service to date, but differs from the PBO in that it is based on current salary levels.

Defined Benefit Plans—Key Assumptions The key assumptions for the plans are summarized below: Successor Predecessor Period From Period From Year Ended December 31, 2020 Non-US US Non-US US Non-US US Weighted-average assumptions used to determine benefit obligations: Discount Rate 1.80% 2.63% - 2.89% 1.80% 1.92% - 2.77% 1.40% 1.82% - 2.60% Rate of compensation increase N/A N/A N/A N/A N/A N/A Successor Predecessor Period From Period From Years Ended December 31, 2020 2019 Non-US Non-US Non-US Non-US Weighted-average assumptions used to determine periodic benefit cost: Discount Rate 1.80 % 1.80 % 2.10 % 2.90 % Expected long-term return on assets 1.20 % 1.20 % 2.90 % 3.70 % Rate of compensation increase N/A N/A N/A N/A Successor Predecessor Period From Period From Years Ended December 31, 2020 2019 US US US US Weighted-average assumptions used to determine periodic benefit cost: Discount Rate 1.92% - 2.77% 1.82% - 2.60% 2.56% - 3.32% 3.65% - 4.29% Expected long-term return on assets 5.00% - 5.80% 5.10% - 6.10% 5.40% - 6.30% 5.40% - 6.50% Rate of compensation increase N/A N/A N/A N/A The discount rates used to calculate the net present value of future benefit obligations for our US plans is based on the average of current rates earned on long-term bonds that receive a Moody’s rating of “Aa” or better. We have determined that the timing and amount of expected cash outflows on our plans reasonably match this index. For our non-US In developing the expected long-term rate of return on assets, we considered the current level of expected returns on risk free investments (primarily government bonds), the historical level of risk premium associated with the other asset classes in which the portfolio is invested and the expectations for future returns of each asset class. The expected return for each asset class was then weighted based on the target asset allocation to develop the expected long-term rate of return on assets for the portfolio. To assist us with this analysis, we employ third-party consultants for our US and non-US Defined Benefit Plans—Plan Assets Non-US As of December 31, 2021, the NDLS pension Scheme targets an asset allocation of 20.0% return-seeking securities (growth) and 80.0% in debt securities (matching) and adopts a de-risking de-risking risk within the matching portfolio in relation to the Scheme’s liabilities. By achieving these objectives, the Trustees believe the Scheme will be able to avoid significant volatility in the contribution rate and provide sufficient assets to cover the Scheme’s benefit obligations. To achieve this the Trustees have given Mercer, the appointed investment manager, full discretion in the day-to-day de-risking The actual fair values of the non-US Successor: As of December 31, 2021 Estimated Fair Value Measurements Carrying Quoted Prices in Significant Other Significant Unobservable Cash and cash equivalents $ 938 $ 938 $ — $ — Equity securities: International companies 10,546 10,546 — — Fixed income securities: Corporate bonds 66,981 66,981 — — Total $ 78,465 $ 78,465 $ — $ — Predecessor: As of December 31, 2020 Estimated Fair Value Carrying Quoted Significant Significant Cash and cash equivalents $ 5,405 $ 5,405 $ — $ — Equity securities: International companies 4,179 4,179 — — Fixed income securities: Corporate bonds 72,407 72,407 — — Other 1,817 1,817 — — Total $ 83,808 $ 83,808 $ — $ — US Plans The fundamental objective of the US plan is to provide the capital assets necessary to meet the financial obligations made to plan participants. In order to meet this objective, the Investment Policy Statement depicts how the investment assets of the plan are to be managed in accordance with the overall target asset allocation of approximately 38.9% equity securities, 59.9% fixed income securities, and 1.2% in cash and equivalents. The target asset allocation is intended to generate sufficient capital to meet plan obligations and provide a portfolio rate of return equal to or greater than the return realized using appropriate blended, market benchmark over a full market cycle (usually a five For investments in mutual funds, the assets of the Trust are subject to the guidelines and limits imposed by such mutual fund’s prospectus and the other governing documentation at the fund level.

The 401(k) Restoration Plan has no assets, and amounts withheld for the 401(k) Restoration Plan are kept by us for general corporate purposes. The investments selected by employees and associated returns are tracked on a phantom basis. Accordingly, we have a liability to the employee for amounts originally withheld plus phantom investment income or less phantom investment losses. We are at risk for phantom investment income and, conversely, benefit should phantom investment losses occur. At December 31, 2021 and 2020, our liability for the 401(k) Restoration Plan was $2.8 million and $7.8 million, respectively, and is included in “Accrued payroll and related costs.” The primary reason for the decrease is due to benefits paid during the calendar year 2021. Subsequent to December 31, 2021, the board has approved the termination of the 401(k) Restoration Plan and distribution of benefits is expected to occur within the next 12 months. In 2005, we enacted a profit sharing plan, the Noble Drilling Services Inc. Profit Sharing Plan, which covers eligible employees, as defined in the plan. Participants in the plan become fully vested in the plan after three years of service. We sponsor other retirement, health and welfare plans and a 401(k) savings plan for the benefit of our employees. On January 1, 2019, the 401(k) savings plan and the profit sharing plan were merged into the Noble Drilling Services Inc. 401(k) and Profit Sharing Plan. Profit sharing contributions are discretionary, require Board of Directors approval and are made in the form of cash. Contributions recorded related to this plan totaled zero, zero, $2.4 million and $2.4 million, respectively, for the period from February 6, 2021 to December 31, 2021, the period from January 1 through February 5, 2021 and the years end December 31, 2020 and 2019. The cost of maintaining these plans for continuing operations aggregated approximately $29.8 million, $1.6 million, $24.9 million and $28.1 million for the period from February 6, 2021 to December 31, 2021, the period from January 1 through February 5, 2021 and the years ended December 31, 2020 and 2019, respectively. We do not provide post-retirement benefits (other than pensions) or any post-employment benefits to our employees.

Commitments and Contingencies	Note 16— Commitments and Contingencies Tax matters In June 2021, the IRS completed its limited scope examination in relation to our CARES Act refund claim and did not propose any adjustments to the taxable years ended December 31, 2012, 2013, 2014, 2018 and 2019. In June 2021, the IRS completed its audit of taxable year 2009 in relation to our foreign tax credit refund claim. No other taxable years are currently under audit in the US. We believe that we have accurately reported all amounts in our returns. Audit claims of approximately $618.0 million attributable to income and other business taxes were assessed against Noble entities in Mexico related to tax years 2007, 2009 and 2010, in Australia related to tax years 2013 to 2016, in Guyana related to tax years 2019 and 2020 in Saudi Arabia related to tax years 2015 to 2019 and against Pacific Drilling entities in Nigeria related to tax years 2010 to 2018. We intend to vigorously defend our reported positions and currently believe the ultimate resolution of the audit claims will not have a material adverse effect on our consolidated financial statements. We operate in a number of countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We recognize uncertain tax positions that we believe have a greater than 50 percent likelihood of being sustained upon challenge by a tax authority. We cannot predict or provide assurance as to the ultimate outcome of any existing or future assessments. Hurricane Ida Personal Injury Claims We have had 14 employees and third parties that were onboard the Noble Globetrotter II related to physical and emotional harm suffered as a result of the incident. See “Note 6— Property and Equipment” for additional information regarding the incident. We have received letters of representation from a number of other potential plaintiffs, and more suits may be brought with respect to the incident. We are in the early stages of litigation. We intend to defend ourselves vigorously against these claims although there is inherent risk in litigation, and we cannot provide assurance as to the outcome of this lawsuit. We have insurance for such claims with a deductible of $5.0 million. Other contingencies Legacy Noble had entered into agreements with certain of our executive officers, as well as certain other employees. These agreements were effective upon a change of control of Noble (within the meaning set forth in the agreements) or a termination of employment in connection with or in anticipation of a change of control and remained effective for three years thereafter. These agreements provided for compensation and certain other benefits under such circumstances. On the Effective Date of our emergence from the Chapter 11 Cases, the Legacy Noble agreements were superseded by new employment agreements. We are a defendant in certain other claims and litigation arising out of operations in the ordinary course of business, including personal injury claims, the resolution of which, in the opinion of management, will not be material to our financial position, results of operations or cash flows. There is inherent risk in any litigation or dispute and no assurance can be given as to the outcome of these claims.

Organization and Basis of Presentation (Policies) - Noble Finance Company [Member]	11 Months Ended
	Dec. 31, 2021
Basis of Presentation	Noble Corporation, an exempted company incorporated in the Cayman Islands with limited liability (“Noble” or “Successor”), is a leading offshore drilling contractor for the oil and gas industry. We provide contract drilling services to the international oil and gas industry with our global fleet of mobile offshore drilling units. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921. As of December 31, 2021, our fleet of 20 drilling rigs consisted of 12 floaters and eight We report our contract drilling operations as a single On July 31, 2020 (the “Petition Date”), our former parent company, Noble Holding Corporation plc (formerly known as Noble Corporation plc), a public limited company incorporated under the laws of England and Wales (“Legacy Noble” or the “Predecessor”), and certain of its subsidiaries, including Noble Finance Company (formerly known as Noble Corporation), a Cayman Islands company (“Finco”), filed voluntary petitions in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”) seeking relief under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”). On September 4, 2020, the Debtors (as defined herein) filed with the Bankruptcy Court the Joint Plan of Reorganization of Noble Corporation plc and its Debtor Affiliates, six Noble Corporation plc, No. 20-33826) The Noble is the successor issuer to Legacy Noble for purposes of and pursuant to Rule 15d-5 Upon emergence, the Company applied fresh start accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 852 – Reorganizations (“ASC 852”). The application of fresh start accounting resulted in a new basis of accounting and the Company becoming a new entity for financial reporting purposes. Accordingly, our financial statements and notes after the Effective Date are not comparable to our financial statements and notes on and prior to that date. See “Note 3—Fresh Start Accounting” for additional information. Finco was an indirect, wholly-owned subsidiary of Legacy Noble prior to the Effective Date and has been a direct, wholly-owned subsidiary of Noble, our parent company, since the Effective Date. Noble’s principal asset is all of the shares of Finco. Finco has no public equity outstanding. The consolidated financial statements of Noble include the accounts of Finco, and Noble conducts substantially all of its business through Finco and its subsidiaries. As such, the terms “Predecessor” and “Successor” also refers to Finco, as the context requires.
Consolidation	Principles of Consolidation The consolidated financial statements include our accounts and those of our wholly-owned subsidiaries and entities in which we hold a controlling financial interest.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially different amounts could have been reported under different conditions, or if different assumptions had been used. We evaluate our estimates and assumptions on a regular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates and assumptions used in preparation of our consolidated financial statements.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits with banks and all highly liquid investments with original maturities of three months or less. Our cash, cash equivalents and short-term investments are subject to potential credit risk, and certain of our cash accounts carry balances greater than the federally insured limits. Cash and cash equivalents are primarily held by major banks or investment firms. Our cash management and investment policies restrict investments to lower risk, highly liquid securities and we perform periodic evaluations of the relative credit standing of the financial institutions with which we conduct business.
Restricted Cash	Restricted Cash We classify restricted cash balances in current assets if the restriction is expected to expire or otherwise be resolved within one year and in other assets if the restriction is expected to expire or otherwise be resolved in more than one year. As of December 31, 2021 and 2020, our Noble restricted cash balance consisted of $2.6 million and $21.7 million, respectively. As of December 31, 2021 and 2020, our Finco restricted cash balance consisted of $2.6 million and $1.7 million, respectively. All restricted cash is recorded in “Prepaid expenses and other current assets.” As of December 31, 2021, our restricted cash balance was associated cash collateral on the Company’s purchase cards and a performance guarantee on the Noble Faye Kozack
Accounts Receivable and Accounts Receivable from Affiliates	Accounts Receivable We record accounts receivable at the amount we invoice our clients, net of allowance for credit losses. We provide an allowance for uncollectible accounts, as necessary. Our allowance for doubtful accounts as of December 31, 2021 and 2020 was zero and $1.1 million, respectively.
Property and Equipment	Property and Equipment Property and equipment is stated at cost, reduced by provisions to recognize economic impairment. Major replacements and improvements are capitalized. When assets are sold, retired or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and the gain or loss is recognized. Drilling equipment and facilities are depreciated using the straight-line method over their estimated useful lives as of the date placed in service or date of major refurbishment. Estimated useful lives of our drilling equipment range from three two Interest is capitalized on long-term construction project using the weighted average cost of debt outstanding during the period of construction. Scheduled maintenance of equipment is performed based on the number of hours operated in accordance with our preventative maintenance program. Routine repair and maintenance costs are charged to expense as incurred; however, the costs of the overhauls and asset replacement projects that benefit future periods and which typically occur every three five We evaluate our property and equipment for impairment whenever there are changes in facts that suggest that the value of the asset is not recoverable. As part of this analysis, we make assumptions and estimates regarding future market conditions. When circumstances indicate that the carrying value of the assets may not be recoverable, management compares the carrying value to the expected undiscounted pre-tax pre-tax
Fair Value Measurements	Fair Value Measurements We measure certain of our assets and liabilities based on a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The three-level hierarchy, from highest to lowest level of observable inputs, are as follows: Level 1 - Valuations based on quoted prices in active markets for identical assets; Level 2 - Valuations based on observable inputs that do not meet the criteria for Level 1, including quoted prices in inactive markets and quoted prices in active markets for similar but not identical instruments; and Level 3 - Valuations based on unobservable inputs.
Revenue Recognition	Revenue Recognition The activities that primarily drive the revenue earned in our drilling contracts include (i) providing a drilling rig and the crew and supplies necessary to operate the rig, (ii) mobilizing and demobilizing the rig to and from the drill site, and (iii) performing rig preparation activities and/or modifications required for the contract. Consideration received for performing these activities may consist of dayrate drilling revenue, mobilization and demobilization revenue, contract preparation revenue and reimbursement revenue. We account for these integrated services provided within our drilling contracts as a single performance obligation satisfied over time and comprised of a series of distinct time increments in which we provide drilling services. Our standard drilling contracts require that we operate the rig at the direction of the customer throughout the contract term (which is the period we estimate to benefit from the corresponding activities and generally ranges from two The amount estimated for variable consideration may be subject to interrupted or restricted rates and is only included in the transaction price to the extent that it is probable that a significant reversal of previously recognized revenue will not occur throughout the term of the contract (“constrained revenue”). When determining if variable consideration should be constrained, management considers whether there are factors outside the Company’s control that could result in a significant reversal of revenue as well as the likelihood and magnitude of a potential reversal of revenue. These estimates are re-assessed Dayrate Drilling Revenue. Mobilization/Demobilization Revenue. lump-sum pre-operating pre-operating In most contracts, there is uncertainty as to the amount of expected demobilization revenue due to contractual provisions that stipulate that certain conditions must be present at contract completion for such revenue to be received and as to the amount thereof, if any. For example, contractual provisions may require that a rig demobilize a certain distance before the demobilization revenue is payable or the amount may vary dependent upon whether or not the rig has additional contracted work within a certain distance from the wellsite. Therefore, the estimate for such revenue may be constrained, as described earlier, depending on the facts and circumstances pertaining to the specific contract. We assess the likelihood of receiving such revenue based on past experience and knowledge of the market conditions. In cases where demobilization revenue is expected to be received upon contract completion, it is estimated as part of the overall transaction price at contract inception and recognized in earnings ratably over the initial term of the contract with an offset to an accretive contract asset. Contract Preparation Revenue. lump-sum Bonuses, Penalties and Other Variable Consideration. re-measure Capital Modification Revenue lump-sum Revenues Related to Reimbursable Expenses Deferred revenues from drilling contracts totaled $27.8 million and $59.9 million at December 31, 2021 and 2020, respectively. Such amounts are included in either “Other current liabilities” or “Other liabilities” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition. Related expenses deferred under drilling contracts totaled $5.7 million at December 31, 2021 as compared to $13.9 million at December 31, 2020 and are included in either “Prepaid expenses and other current assets,” “Other assets” or “Property and equipment, net” in the accompanying Consolidated Balance Sheets, based upon our expected time of recognition. We record reimbursements from customers for “out-of-pocket”
Income Taxes	Income Taxes Income taxes are based on the laws and rates in effect in the countries in which operations are conducted or in which we or our subsidiaries are considered resident for income tax purposes. In certain circumstances, we expect that, due to changing demands of the offshore drilling markets and the ability to redeploy our offshore drilling units, certain of such units will not reside in a location long enough to give rise to future tax consequences. As a result, no deferred tax asset or liability has been recognized in these circumstances. Should our expectations change regarding the length of time an offshore drilling unit will be used in a given location, we will adjust deferred taxes accordingly. Deferred tax assets and liabilities are recognized for the anticipated future tax effects of temporary differences between the financial statement basis and the tax basis of our assets and liabilities using the applicable jurisdictional tax rates at year-end. We operate through various subsidiaries in numerous countries throughout the world, including the United States. Consequently, we are subject to changes in tax laws, treaties or regulations or the interpretation or enforcement thereof in the United States, UK and any other jurisdictions in which we or any of our subsidiaries operate or are resident. Our income tax expense is based upon our interpretation of the tax laws in effect in various countries at the time that the expense was incurred. If the IRS or other taxing authorities do not agree with our assessment of the effects of such laws, treaties and regulations, this could have a material adverse effect on us including the imposition of a higher effective tax rate on our worldwide earnings or a reclassification of the tax impact of our significant corporate restructuring transactions. The Company has adopted an accounting policy to look through the outside basis of partnerships and all other flow-through entities and exclude these from the computation of deferred taxes.
Insurance Reserves	Insurance Reserves We maintain various levels of self-insured retention for certain losses including property damage, loss of hire, employment practices liability, employers’ liability and general liability, among others. We accrue for property damage and loss of hire charges on a per event basis. Employment practices liability claims are accrued based on actual claims during the year. Maritime employer’s liability claims are generally estimated using actuarial determinations. General liability claims are estimated by our internal claims department by evaluating the facts and circumstances of each claim (including incurred but not reported claims) and making estimates based upon historical experience with similar claims. At December 31, 2021 and 2020, loss reserves for personal injury and protection claims totaled $14.8 million and $30.9 million, respectively, and such amounts are included in “Other current liabilities” and “Other current liabilities” or “Liabilities subject to compromise,” respectively, in the accompanying Consolidated Balance Sheets.
Earnings per Share	Earnings per Share Our unvested share-based payment awards, which contain non-forfeitable two-class two-class two-class
Share-Based Compensation Plans and Liability-Classified Awards	Share-Based Compensation Plans We record the grant date fair value of share-based compensation arrangements as compensation cost using a straight-line method over the service period. Share-based compensation is expensed or capitalized based on the nature of the employee’s activities. Liability-Classified Awards The Company classified certain awards that will be settled in cash as liability awards. The fair value of a liability-classified award is determined on a quarterly basis beginning at the grant date until final vesting. Changes in the fair value of liability-classified awards are expensed or capitalized based on the nature of the employee’s activities over the vesting period of the award.
Litigation Contingencies	Litigation Contingencies We are involved in legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. Certain of these matters include speculative claims for substantial or indeterminate amounts of damages. We record a liability when we believe that it is both probable that a loss has been incurred and the amount can be reasonably estimated. If we determine that a loss is reasonably possible and the loss or range of loss can be estimated, we disclose the possible loss in the notes to the consolidated financial statements. We review the developments in our contingencies that could affect the amount of the provisions that has been previously recorded, and the matters and related possible losses disclosed. We make adjustments to our provisions and changes to our disclosures accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Significant judgement is required to determine both the probability and the estimated amount.
Foreign Currency Translation	Foreign Currency Translation Although we are a Cayman Islands company, our functional currency is the US dollar, and we define any non-US non-US currency transaction gains and losses are included in net income or loss. In non-US
