2. Summary of Significant Accounting Policies (a) Newly Adopted Accounting Standards Accounting Standards Update, or ASU, 2023-09 - Income Taxes (Topic 740): Improvements to Income Tax Disclosures. In December 2023, the FASB issued ASU 2023-09, which modifies the rules on income tax disclosures to require companies to disclose specific categories in the rate reconciliation, the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and income tax expense or benefit from continuing operations (separated by federal, state, and foreign). The updated standard was effective for annual periods beginning after December 15, 2024. The updated standard impacted only the financial statement disclosures, with no impact on the Company’s results of operation, cash flows and financial position. The required disclosures are included in Note 20. “Income Taxes.” (b) Accounting Standards Not Yet Implemented ASU 2024-03 - Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses . In November 2024, the FASB issued ASU 2024-03, which require disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments aim to improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. The updated standard is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact that the updated standard will have on its financial statement disclosures. ASU 2025-11 - Interim Reporting (Topic 270 ): Narrow-Scope Improvements . In December 2025, FASB issued ASU 2025-11 to clarify interim financial reporting guidance under Topic 270. The amendments aim to make the interim reporting requirements easier to navigate and apply. The amendments do not change the substance of existing interim reporting requirements but reorganize and clarify when and how the guidance applies. The amendments also introduce a new disclosure principle requiring entities to disclose events and changes occurring since the end of the last annual reporting period that have a material impact on the entity. The updated standard will be effective for annual periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. The Company is currently evaluating the impact that the updated standard will have on its financial statement disclosures. There have been no other recent accounting pronouncements not yet effective that have significance, or potential significance, to the Company’s Consolidated Financial Statements. (c) Reclassifications Certain amounts in the prior period Consolidated Balance Sheet have been reclassified to conform to the current period presentation. These reclassifications relate to the presentation of contract obligations which were previously reported within a different financial statement line item. These changes had no impact on the Company’s previously reported net income (loss). The preparation of Consolidated Financial Statements in conformity with U.S. GAAP requires management to make certain judgements, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and contingent liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ materially from those estimates. Significant items subject to such estimates and assumptions include asset retirement obligations; useful lives for depreci ation, depletion and amortization; expected credit losses; deferred income tax assets and liabilities; values of coal properties; goodwill; workers’ compensation liability; and other contingencies. Financial Statements of Foreign Operations The reporting currency of the Company is the U.S. Dollar, or US$. Functional currency is determined by the primary economic environment in which an entity operates. The functional currency of the Company and its subsidiaries is the US$, with the exception of two foreign operating subsidiaries, Coronado Curragh Pty Ltd, or Curragh, and its immediate parent, Coronado Australia Holdings Pty Ltd, or CAH, whose functional currency is the Australian dollar, or A$, since Curragh’s predominant sources of operating expenses are denominated in that currency. Assets and liabilities are translated at the year-end exchange rate and items in the statement of operations are translated at average rates with gains and losses from translation recorded in other comprehensive losses. Foreign Currency Transactions Monetary assets and liabilities are remeasured at year-end exchange rates while non-monetary items are remeasured at historical rates. Gains and losses from foreign currency remeasurement related to Curragh’s US$ receivables are included in coal revenues. All other gains and losses from foreign currency remeasurement and foreign currency forward contracts are included in “Other, net,” with the exception of foreign currency gains or losses on long-term intercompany loan balances which are classified within “Accumulated other comprehensive losses.” The Company may periodically enter into arrangements that protect against the volatility of foreign currency, including forward currency derivative contracts. Refer to Note 21. “Derivatives and Fair Value Measurement” for The total aggregate impact of foreign currency transaction gains or losses on the Consolidated Statements of Operations and Comprehensive Income was a net loss of $ 6.2 21.6 $ 2.5 million for the years ended December 31, 2025, 2024 and 2023, respectively. The total impact of foreign currency transactions related to US$ coal sales in Australia (included in the total above) was a net loss of $ 8.8 8.4 million and net loss of $ 1.0 million for the years ended December 31, 2025, 2024 and 2023, respectively. (f) Cash and Cash Equivalents Cash and cash equivalents include cash at bank and short-term, highly liquid investments with an original maturity date of three months or less. The Company had $ 106.9 221.4 million of short-term, highly liquid investments classified as cash equivalents as of December 31, 2025 and 2024, respectively. “Cash and cash equivalents,” as disclosed in the accompanying Consolidated Balance Sheets, includes $ 0.3 million of restricted cash at December 31, 2025 and 2024. (g) Trade Accounts Receivables Trade accounts receivables represent customer obligations that are derived from revenue recognized from contracts with customers. The Company extends trade credit to its customers in the ordinary course of business based on an evaluation of the individual customer’s financial condition. Trade receivables are initially recorded at fair value and subsequently at amortized cost, less any Expected Credit Losses, or ECL. The Company determines ECL on a forward -looking basis for the expected lifetime losses on trade accounts receivable. The amount of ECL is updated at each reporting date to reflect changes in credit risk since initial recognition of the respective financial instrument. The ECL is estimated based on the Company’s historic credit loss experience, adjusted for factors that are specific to the financial asset, general economic conditions, financial asset type, term and an assessment of both the current as well as forecast conditions, including expected timing of collection, at the reporting date, modified for credit enhancements such as letters of credit obtained. To measure ECL, trade receivables have been grouped based on shared credit risk characteristics and the days The amount of credit loss is recognized in the Consolidated Statements of Operations and Comprehensive Income within “Provision for discounting and credit losses.” The Company writes off a financial asset when there is information indicating there is no realistic prospect of recovery of the asset from the counterparty. Subsequent recoveries of amounts previously written off are credited against “Provision for discounting and credit losses” in the Consolidated Statements of Operations and Comprehensive Income. Coal is recorded as inventory at the point in time the coal is extracted from the mine. Raw coal represents coal stockpiles that may be sold in current condition or may be further processed prior to shipment to a customer. Saleable coal represents coal stockpiles which require no further processing prior to shipment to a customer. Coal inventories are stated at the lower of average cost and net realizable value. The cost of coal inventories is determined based on an average cost of production, which includes all costs incurred to extract, transport and process the coal. Net realizable value considers the estimated sales price of the particular coal product, less applicable selling costs, depending on the location of the coal stockpile, and, in the case of raw coal, estimated remaining processing costs. Supplies inventory is comprised of replacement parts for operational equipment and other miscellaneous materials and supplies required for mining, which are stated at cost on the date of purchase. Supplies inventory is valued at the lower of average cost or net realizable value, less a reserve for obsolete or surplus items. This reserve incorporates several factors, such as anticipated usage, inventory turnover and inventory levels. It is not customary to sell these inventories; the Company plans to use them in mining operations as needed. (i) Property, Plant and Equipment, Impairment of Long-Lived Assets and Goodwill Property, Plant, and Equipment Costs for mine development incurred to expand capacity of operating mines or to develop new mines and certain mining equipment are capitalized and charged to operations on the hours of usage or units of production method over the estimated proven and probable reserve tons directly benefiting from the capital expenditures. Mine development costs include costs incurred for site preparation and development of the mines during the development stage. Mineral rights and reserves acquired are measured at cost and are depleted on a units-of- production method over the estimated proven and probable reserve tons of the relevant mineral property. Capitalized costs related to internal-use software are amortized on a straight-line basis over the estimated useful lives of the assets. Property, plant, and equipment are recorded at cost and include expenditures for improvements when they substantially increase the productive lives of existing assets. Depreciation is calculated using the straight-line method over the estimated useful lives of the depreciable assets of 3 10 years for machinery, mining equipment and transportation vehicles, 5 10 years for office equipment, and 10 20 years for plant, buildings and improvements. Maintenance and repair costs are expensed to operations as incurred. When equipment is retired or disposed, the related cost and accumulated depreciation are removed from the respective accounts and any gain or loss on disposal is recognized in operations. Impairment of long-lived assets Long-lived assets, such as property, plant, and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as In circumstances in which the Company intends to sell a long-lived or asset group that did not satisfy the criteria to be classified as “held-for-sale,” an impairment charge is recorded when the carrying amount of the disposal group exceeds its estimated fair value, less costs to sell. The Company recognized an impairment charge of $ 10.6 million against property, plant and equipment relating to a long-standing non-core idle asset within the U.S. Operation for the year ended December 31, 2024. The no impairment charges were required at any of the Company’s mining assets for the years ended December 31, 2025 and 2023. Goodwill Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. In connection with the Buchanan acquisition on March 31, 2016, the Company recorded goodwill in the amount of $ 28.0 performed a qualitative assessment to determine if impairment was required at December 31, 2025 and 2024. Based upon the Company’s qualitative assessment, it is more likely than not that the fair value of the reporting unit is greater than its carrying amount at December 31, 2025 and 2024. As a result, no and the balance of goodwill at both December 31, 2025 and 2024 was $ 28.0 million. The Company has not noted any indicators of impairment since the acquisition date. Goodwill is not amortized but is reviewed for impairment annually or when circumstances or other events indicate that impairment may have occurred. The Company follows the guidance in Accounting Standards Update 2017- Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment Company makes a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount. Circumstances that are considered as part of the qualitative assessment and could trigger a quantitative impairment test include, but are not limited to, a significant adverse change in the business climate; a significant adverse legal judgment; adverse cash flow trends; an adverse action or assessment by a government agency; unanticipated competition; and a significant restructuring charge within a reporting unit. If a quantitative assessment is determined to be necessary, the Company compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, the Company recognizes an impairment charge for the amount by which the carrying amount exceeds its fair value to the extent of the amount of goodwill allocated to that reporting unit. The Company defines reporting units at the mining asset level. For purposes of testing goodwill for impairment, goodwill has been allocated to the reporting units to the extent it relates to each reporting unit. (j) Asset Retirement Obligations The Company’s asset retirement obligation, or ARO, liabilities primarily consist of estimates of the cost of reclamation of surface land and support facilities at both surface and underground mines in accordance with applicable reclamation laws and regulations in the U.S. and Australia as defined by each mining permit. The Company estimates its ARO liabilities for final reclamation and mine closure based upon detailed engineering calculations of the amount and timing of the future cash spending for a third party to perform the required work. Spending estimates are escalated for inflation and then discounted at the credit-adjusted, risk-free rate. The Company records an ARO asset associated with the discounted liability for final reclamation and mine closure. The obligation and corresponding asset are recognized in the period in which the liability is incurred. The ARO asset is amortized on the units-of-production method over the expected life of the related asset and the ARO liability is accreted to the projected spending date. As changes in estimates occur (such as mine plan revisions, changes in estimated costs or changes in timing of the performance of reclamation activities), the revisions to the obligation and asset are recognized at the appropriate credit-adjusted, risk-free rate. The Company also recognizes an obligation for contemporaneous reclamation liabilities incurred as a result of surface mining. Contemporaneous reclamation consists primarily of grading, topsoil replacement and re-vegetation of backfilled pit areas. To settle the liability, the obligation is paid, and to the extent there is a difference between the liability and the amount of cash paid, a gain or loss upon settlement is recorded. The Company annually reviews its estimated future cash flows for its asset retirement obligations. Borrowing costs are recognized as an expense when they are incurred, except for interest charges attributable to major projects with substantial development and construction phases, which are capitalized as part of the cost of the asset. There was no interest capitalized during the years ended December 31, 2025, 2024 and 2023. From time to time, the Company enters into contractual agreements to lease property, plant and equipment. In addition, the Company also enters into mining services contracts which may include embedded leases of mining equipment. Based upon the Company’s assessment of the terms of a specific lease agreement, the Company classifies a lease as either finance or operating. Finance Leases Right of Use, or ROU, assets related to finance leases are presented in “Property, plant and equipment, net” on the Consolidated Balance Sheets. Lease liabilities related to finance leases are presented in “Lease Liabilities” (current) and “Lease Liabilities” (non-current) on the Consolidated Balance Sheets. Finance lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of the future lease payments over the lease term. The discount rate used to determine the present value of the lease payments is the rate implicit in the lease unless that rate cannot be readily determined, in which case the Company utilizes its incremental borrowing rate in determining the present value of the future lease payments. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow, on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. Operating Leases ROU assets related to operating leases are presented as “Right of Use assets – operating leases, net” on the Consolidated Balance Sheets. Lease liabilities related to operating leases that are subject to the Accounting Standards Codification, or ASC, 842 measurement requirements, such as operating leases with lease terms greater than twelve months, are presented in “Lease Liabilities” (current) and “Lease Liabilities” (non -current) on the Consolidated Balance Sheets. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of the future lease payments over the lease term. The discount rate used to determine the present value of the lease payments is the rate implicit in the lease unless that rate cannot be readily determined, in which case, the Company utilizes its incremental borrowing rate in determining the present value of the future lease payments. The incremental borrowing rate is the rate of interest that the Company would have to pay to borrow, on a collateralized basis over a similar term, an amount equal to the lease payments in a similar economic environment. Operating lease ROU assets may also include any cumulative prepaid or accrued rent when the lease payments are uneven throughout the lease term. The ROU assets and lease liabilities may also include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The ROU asset includes any lease payments made and lease incentives received prior to the commencement date. The Company has lease arrangements with lease and non-lease components which are accounted for separately. Non-lease components of the lease payments are expensed as incurred and are not included in determining the present value. (m) Royalties Lease rights to coal lands are often acquired in exchange for royalty payments. For our Australian Operations, royalties are payable monthly as a percentage of the gross realization from the sale of the coal mined using surface mining methods and underground methods. At our U.S. Operations, royalties are payable monthly as a percentage of the gross realization for coal produced using underground mining methods. Advance mining royalties are advance payments made to lessors under terms of mineral lease agreements that are recoupable against future production. The Company had advance mining royalties of $ 5.7 9.8 respectively, included in “Other current assets” as of December 31, 2025 and 2024. The Stanwell rebate relates to a contractual arrangement entered into by the Company and Stanwell Corporation Limited, a State of Queensland-owned electricity generator, which required payment of a rebate for export coal sold from some of Curragh’s mining tenements. The rebate obligation is accounted for as an executory contract and the expense is recognized as incurred. On November 27, 2025, the Company entered into a Second Amendment Deed with Stanwell that, among other matters, waived the rebate amounts that would have otherwise been payable by the Company from January 1, 2026 until the final delivery date pursuant to the ACSA, which date is expected to occur in the first half of 2027. Refer to Note 14. “Contract Obligations” for further information. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Once a contract is identified, the Company evaluates whether the combined or single contract should be accounted for as more than one performance obligation. The Company recognizes revenue when control is transferred to the customer. For the Company’s contracts, in order to determine the point in time when control transfers to customers, the Company uses standard shipping terms to determine the timing of transfer of legal title and the significant risks and rewards of ownership. The Company also considers other indicators including timing of when the Company has a present right to payment and when physical possession of products is transferred to customers. The amount of revenue recognized includes any adjustments for variable consideration, which is included in the transaction price and allocated to each performance obligation based on the relative standalone selling price. The variable consideration is estimated through the course of the contract using management’s best estimates. The majority of the Company’s revenue is derived from short-term contracts where the time between confirmation of sales orders and collection of cash is not more than a few months. During 2025, the Company secured long- term contracts with varying pricing arrangements and including prepayments. Refer to Note 14. “Contract Obligations” for further information. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction that are collected by the Company from a customer are excluded from revenue. Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Revenue is recognized at a point in time. The Company’s contracts have multiple performance obligations as the promise to transfer the individual unit of coal is separately identifiable from other units of coal promised in the contracts and, therefore, distinct. Performance obligations, as described above, primarily relate to the Company’s promise to deliver a designated quantity and type of coal within the quality specifications stated in the contract. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation on a relative standalone selling price basis. The standalone selling price is determined at each contract inception using an adjusted market assessment approach. This approach focuses on the amount that the Company believes the market is willing to pay for a good or service, considering market conditions, such as benchmark pricing, competitor pricing, market awareness of the product and current market trends that affect the pricing. Warranties provided to customers are assurance-type warranties on the fitness of purpose and merchantability of the Company’s goods. The Company does not provide service-type warranties to customers. Shipping and Handling For Free on Rail sales, the Company accounts for shipping and handling activities as a separate performance obligation after the customer obtains control of the good. In this instance, shipping and handling costs paid to third party carriers and invoiced to coal customers are recorded as freight expense and other revenues, respectively. Contract Balances Contract assets, when present, are recorded separately from trade receivables in the Company's Consolidated Balance Sheets and are reclassified to trade receivables as title passes to the customer and the Company's right to consideration becomes unconditional. Credit is extended based on an evaluation of a customer's financial condition and a customer's ability to perform its obligations. The Company typically does not have contract assets that are stated separately from trade receivables since the Company's performance obligations are satisfied as control of the goods or services passes to the customer, thereby granting the Company an unconditional right to receive consideration. Contract liabilities relate to consideration received in advance of the satisfaction of the Company's performance obligations. Contract liabilities are recognized as revenue at the point in time when control of the goods passes to the customer. Refer to Note 14. “Contract Obligations” for further information. The Company has commodity price risk arising from fluctuations in domestic and global coal prices. The Company’s principal philosophy is not to hedge against movements in coal prices unless there are exceptional circumstances. Any potential hedging of coal prices would be through fixed price contracts. The Company is also exposed to commodity price risk related to diesel fuel purchases. The Company may periodically enter into arrangements that protect against the volatility in fuel prices as follows: • entering into fixed price contracts to purchase fuel for the U.S. Operations. • entering into derivative financial instruments to hedge exposures to fuel price fluctuations. Refer to Note 21. “Derivatives and Fair Value Measurement”. (q) Derivative Accounting The Company recognizes at fair value all contracts meeting the definition of a derivative as assets or liabilities in the Consolidated Balance Sheets. With respect to derivatives used in hedging activities, the Company assesses, both at inception and at least quarterly thereafter, whether such derivatives are highly effective at offsetting the changes in the anticipated exposure of the hedged item. The effective portion of the change in the fair value of derivatives designated as a cash flow hedge is recorded in “Accumulated other comprehensive income (loss)” until the hedged transaction impacts reported earnings, at which time any gain or loss is reclassified to earnings. To the extent that periodic changes in the fair value of derivatives deemed highly effective exceeds such changes in the hedged item, the ineffective portion of the periodic non-cash changes are recorded in earnings in the period of the change. If the hedge ceases to qualify for hedge accounting, the Company prospectively recognizes changes in the fair value of the instrument in earnings in the period of the change. The potential for hedge ineffectiveness is present in the design of certain of the Company’s cash flow hedge relationships. The Company’s asset and liability derivative positions are offset on a counterparty-by-counterparty basis if the contractual agreement provides for the net settlement of contracts with the counterparty in the event of default or termination of any one contract. The Company uses the asset and liability approach to account for income taxes as required by ASC 740, Income Taxes, which requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Valuation allowances are provided when necessary to reduce deferred income tax assets to the amount expected to be realized, on a “more likely than not” basis. The Company recognizes the benefit of an uncertain tax position that it has taken or expects to take on income tax returns it files if such tax position is more likely than not to be sustained on examination by the taxing authorities, based on the technical merits of the position. These tax benefits are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The Company’s foreign structure consists of Australian entities which are treated as corporations subject to tax under Australian taxing authorities. The Australian entities are treated as a branch for U.S. tax purposes and all income flows through the ultimate parent (the Company). (s) Fair Value Measurements The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most relevant market. When considering market participant assumptions in fair value measurements, the Company distinguishes between observable and unobservable inputs, which are categorized in one of three levels of inputs. Refer to Note 21. “Derivatives and Fair Value Measurement” for detailed information related to the Company’s fair value policies and disclosures. (t) Stock-based Compensation The Company has a stock-based compensation plan which allows for the grant of certain equity-based incentives including stock options, performance stock units, or PSUs, and restricted stock units, or RSUs, to employees and executive directors, valued in whole or in part with reference to the Company’s CDIs or equivalent common shares (on a 10 :1 CDI to common share ratio). The grant-date fair value of stock option award is estimated on the date of grant using Black-Scholes-Merton option-pricing model. For certain options and PSUs, the Company includes a relative Total Stockholder Return, or TSR, modifier to determine the number of shares earned at the end of the performance period. The fair value of awards that include the TSR modifier is determined using a Monte Carlo valuation model. The expense for these equity-based incentives is based on their fair value at date of grant and is amortized over the required service period, generally the vesting period. The Company accounts for forfeitures as and when they occur. Refer to Note 19. “Stock-Based Compensation” for detailed information related to the Company’s stock-based compensation plans. u) (Loss) Earnings per Share Basic earnings per share is computed by dividing net income attributable to stockholders of the Company by the weighted-average number of shares of common stock outstanding during the reporting period. Diluted net income per share is computed using the weighted-average number of shares of common stock and dilutive potential shares of common stock outstanding during the period. Dilutive potential shares of common stock primarily consist of employee stock options and restricted stock. (v) Deferred Debt Issuance Costs The Company capitalizes costs incurred in connection with new borrowings, the establishment or enhancement of credit facilities and the issuance of debt securities. These costs are amortized as an adjustment to interest expense over the life of the borrowing or term of the credit facility using the effective interest method. Deferred debt issuance costs related to a recognized liability are presented in the Consolidated Balance Sheets as a direct reduction from the carrying amount of that liability whereas debt issuance costs related to a revolving credit facility are shown as an asset and amortized over the life of the facility on a straight-line basis and included in “Interest expense, net” in the Company’s Consolidated Statements of Operations and Comprehensive Income. For information on the unamortized balance of deferred debt issuance costs related to outstanding debt, see Note 15. “Interest Bearing Liabilities”. |
