Basis of Presentation	1. The accompanying unaudited condensed consolidated financial statements include the accounts of Arch Resources, Inc. (“Arch Resources”) and its subsidiaries (“Arch” or the “Company”). Unless the context indicates otherwise, the terms “Arch” and the “Company” are used interchangeably in this Quarterly Report on Form 10-Q. The Company’s primary business is the production of metallurgical and thermal coal from underground and surface mines located throughout the United States, for sale to steel producers, utility companies, and industrial accounts both in the United States and around the world. The Company currently operates mining complexes in West Virginia, Wyoming and Colorado. All subsidiaries are wholly owned. Intercompany transactions and accounts have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial reporting and U.S. Securities and Exchange Commission regulations. In the opinion of management, all adjustments, consisting of normal, recurring accruals considered necessary for a fair presentation, have been included. Results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022. These financial statements should be read in conjunction with the audited financial statements and related notes as of and for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the U.S. Securities and Exchange Commission.

Accounting Policies	2. Recently Adopted Accounting Guidance In August 2020, the FASB issued ASU 2020-06 , The if-converted method assumes the conversion of convertible instruments occurs at the beginning of the reporting period and diluted weighted average shares outstanding includes the common shares issuable upon conversion of the convertible instruments. ASU 2020-06 is effective for public business entities, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. The Company adopted ASU 2020-06 on January 1, 2022 under the modified retrospective approach. Upon issuance of the Company's $155.3 million principal amount of 5.25 % convertible senior notes due 2025 (the "Convertible Notes" or “Convertible Debt”) in November 2020, the Company bifurcated the debt and equity components of the Convertible Notes to long-term debt and additional paid-in capital in its consolidated balance sheet. The amount recorded to additional paid-in capital represented a debt discount that was being amortized to interest expense over the life of the Convertible Notes. As part of the adoption of ASU 2020-06, the Company (i) reversed the equity component recorded to additional paid-in capital of $39.2 million, (ii) recorded a cumulative effect of the adoption of ASU 2020-06 of $6.7 million to retained earnings, representing a reversal of the debt discount that was amortized to interest expense, and (iii) an offsetting increase in debt. See Additionally, upon adoption of ASU 2020-06, the treasury stock method utilized by the Company to calculate earnings per share through December 31, 2021 is no longer permitted. Accordingly, the Company has transitioned to the if-converted method utilizing the modified retrospective approach. For the three and six months ended June 30, 2022, under the previous treasury stock method, the diluted earnings per share would have been approximately $19.68 and $33.55 , respectively. As a result of the adoption of ASU 2020-06, diluted earnings per share decreased by Recent Accounting Guidance Issued Not Yet Effective There are no new pronouncements issued but not yet effective expected to have a material impact on the Company’s financial position, results of operations, or liquidity.

Derivatives	6. Diesel fuel price risk management The Company is exposed to price risk with respect to diesel fuel purchased for use in its operations. The Company anticipates purchasing approximately 40 to 45 million gallons of diesel fuel for use in its operations during 2022. To protect the Company’s cash flows from increases in the price of diesel fuel for its operations, the Company has purchased heating oil call options. At June 30, 2022, the Company had protected the price of expected diesel fuel purchases for 2022 with approximately per gallon. These positions are not designated as hedges for accounting purposes, and therefore, changes in the fair value are recorded immediately to earnings. Coal price risk management positions The Company may sell or purchase forward contracts, swaps and options in the over-the-counter coal market in order to manage its exposure to coal prices. The Company has exposure to the risk of fluctuating coal prices related to forecasted, index-priced sales or purchases of coal or to the risk of changes in the fair value of a fixed price physical sales contract. Certain derivative contracts may be designated as hedges of these risks. At June 30, 2022, the Company held derivatives for risk management purposes that are expected to settle in the following years: (Tons in thousands) 2022 Coal sales 116 Coal purchases — Tabular derivatives disclosures The Company has master netting agreements with all of its counterparties which allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. Such netting arrangements reduce the Company’s credit exposure related to these counterparties.

The Term Loan Debt Facility was issued at 99.50% of the face amount and will mature on March 7, 2024. The term loans provided under the Term Loan Debt Facility (the “Term Loans”) are subject to quarterly principal amortization payments in an amount equal to $750,000 . The interest rate on the Term Loan Debt Facility is, at the option of Arch Resources, either (i) LIBOR plus an applicable margin of The Term Loan Debt Facility is guaranteed by all existing and future wholly owned domestic subsidiaries of the Company (collectively, the “Subsidiary Guarantors” and, together with Arch Resources, the “Loan Parties”), subject to customary exceptions, and is secured by first priority security interests on substantially all assets of the Loan Parties, including 100% of the voting equity interests of directly owned domestic subsidiaries and 65% of the voting equity interests of directly owned foreign subsidiaries, subject to customary exceptions. During the first half of 2022, the Company repaid $272.3 million of the Term Loans leaving a remaining balance of $8.0 million. The remaining balance of $8.0 million was left as certain terms and conditions governing the Term Loan are incorporated into the Company’s outstanding indebtedness. As a result of the repayment, the Company recorded million as “net loss resulting from early retirement of debt” during the six months ended June 30 2022 in the accompanying Condensed Consolidated Income Statements relating to deferred financing fees, original issue discount, and the ineffective portion of an interest rate swap designated as a cashflow hedge, partially offset by gains on repurchases of the Term Loans. Accounts Receivable Securitization Facility On September 30, 2020, the Company amended and extended its existing trade accounts receivable securitization facility provided to Arch Receivable Company, LLC, a special-purpose entity that is a wholly owned subsidiary of Arch Resources (“Arch Receivable”) (the “Securitization Facility”), which supports the issuance of letters of credit and requests for cash advances. The amendment to the Securitization Facility reduced the size of the facility from $160 million to $110 million of borrowing capacity and extended the maturity date to September 29, 2023. Under the Securitization Facility, Arch Receivable, Arch Resources and certain of Arch Resources’s subsidiaries party to the Securitization Facility have granted to the administrator of the Securitization Facility a first priority security interest in eligible trade accounts receivable generated by such parties from the sale of coal and all proceeds thereof. As of June 30, 2022, letters of credit totaling Inventory-Based Revolving Credit Facility On September 30, 2020, Arch Resources amended the senior secured inventory-based revolving credit facility in an aggregate principal amount of $50 million (the “Inventory Facility”) with Regions Bank (“Regions”) as administrative agent and collateral agent, as lender and swingline lender (in such capacities, the “Lender”) and as letter of credit issuer. Availability under the Inventory Facility is subject to a borrowing base consisting of (i) 85% of the net orderly liquidation value of eligible coal inventory, plus (ii) the lesser of (x) 85% of the net orderly liquidation value of eligible parts and supplies inventory and (y) 35% of the amount determined pursuant to clause (i), plus (iii) 100% of Arch Resources’s Eligible Cash (defined in the Inventory Facility), subject to reduction for reserves imposed by Regions. The amendment of the Inventory Facility extended the maturity of the facility to September 29, 2023; eliminated the provision that accelerated maturity upon Liquidity (as defined in the Inventory Facility) falling below a specified level; and reduced the minimum Liquidity requirement from $175 million to $100 million. Additionally, the amendment included provisions that reduce the advance rates for coal inventory and parts and supplies, depending on “liquidity.” The Inventory Facility contains certain customary affirmative and negative covenants; events of default, subject to customary thresholds and exceptions; and representations, including certain cash management and reporting requirements that are customary for asset-based credit facilities. The Inventory Facility also includes a requirement to maintain liquidity equal to or exceeding $100 million at all times. As of June 30, 2022, letters of credit totaling $27.7 million were outstanding under the facility with $22.3 million available for borrowings. Equipment Financing On March 4, 2020, the Company entered into an equipment financing arrangement accounted for as debt. The Company received million in exchange for conveying an interest in certain equipment in operation at its Leer mine and entered into a master lease arrangement for that equipment. The financing arrangement contains customary terms and events of default and provides for maturing on March 4, 2024. Upon maturity, all interests in the subject equipment will revert back to the Company. On July 29, 2021, the Company entered into an additional equipment financing arrangement accounted for as debt. The Company received maturing on February 1, 2025. Upon maturity, the Company will have the option to purchase the equipment. Tax Exempt Bonds On July 2, 2020, the West Virginia Economic Development Authority (the “Issuer”) issued $53.1 million aggregate principal amount of Solid Waste Disposal Facility Revenue Bonds (Arch Resources Project), Series 2020 (the “Tax Exempt Bonds”) pursuant to an Indenture of Trust dated as of June 1, 2020 (the “Indenture of Trust”) between the Issuer and Citibank, N.A., as trustee (the “Trustee”). On March 4, 2021, the Issuer issued an additional million of Series 2021 Tax Exempt Bonds. The proceeds of the Tax Exempt Bonds were loaned to the Company pursuant to a Loan Agreement dated as of June 1, as supplemented by a First Amendment to Loan Agreement dated as of March 1, 2021 (collectively, the “Loan Agreement”), each between the Issuer and the Company. The Tax Exempt Bonds are payable solely from payments to be made by the Company under the Loan Agreement as evidenced by a Note from the Company to the Trustee. The proceeds of the Tax Exempt Bonds have been used to finance certain costs of the acquisition, construction, reconstruction, and equipping of solid waste disposal facilities at the Company’s Leer South development, and for capitalized interest and certain costs related to issuance of the Tax Exempt Bonds. The Tax Exempt Bonds bear interest payable each January 1 and July 1, commencing January 1, 2021 for the Series 2020 and July 1, 2021 for the Series 2021, and have a final maturity of July 1, 2045; however, the Tax Exempt Bonds are subject to mandatory tender on July 1, 2025 at a purchase price equal to 100% of the principal amount of the Tax Exempt Bonds, plus accrued interest to July 1, 2025. The Series 2020 and Series 2021 Tax Exempt Bonds bear interest of Convertible Debt On November 3, 2020, the Company issued $155.3 million in aggregate principal amount of 5.25% convertible senior notes due 2025 (“Convertible Notes ” or “Convertible Debt”). The net proceeds from the issuance of the Convertible Notes, after deducting offering related costs of $5.1 million and cost of a “Capped Call Transaction” as defined below of $17.5 million, were approximately $132.7 million. The Convertible Notes bear interest at the annual rate of 5.25%, payable semiannually in arrears on May 15 and November 15 of each year, beginning on May 15, 2021, and will mature on November 15, 2025, unless earlier converted, redeemed or repurchased by the Company. The Convertible Notes are convertible into cash, shares of the Company’s common stock or a combination thereof, at the Company’s election, at an initial conversion rate of 26.7917 shares of common stock per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $37.325 per share, subject to adjustment pursuant to the terms of the indenture governing the Convertible Notes (the "Indenture"). The conversion rate of the Convertible Notes may be adjusted in certain circumstances, including in connection with a conversion of the Convertible Notes made following certain fundamental changes and under other circumstances set forth in the Indenture such as a declaration of a dividend. During the second quarter of 2022, the conversion price was revalued to $35.448 per share as a result of the second quarter dividend declaration. The Convertible Notes may be converted in certain circumstances, including at any time after, and including, July 15, 2025 until the close of business on the second scheduled trading day immediately before the maturity date. During the second quarter of 2022, the common stock sale condition of the Convertible Notes was satisfied. As described in the Indenture, this condition is satisfied when the closing stock price exceeds trading days prior to quarter end. As a result, the Convertible Notes are currently convertible at the election of noteholders during the third quarter of 2022 and are classified as current maturities of debt on the Company’s Consolidated Balance Sheet at June 30, 2022. In May 2022, the Company entered into a negotiated exchange (the “exchanges”) of $125.2 million principal amount of the Convertible Notes for aggregate consideration consisting of $130.1 million in cash and approximately 2.6 million shares of Arch Resources common stock. Approximately In connection with the exchanges in the second quarter of 2022, the Company recognized a total loss of $9.6 million which includes an inducement premium payment of $4.7 million, unamortized deferred financing fees of $3.4 million and professional fees of $1.5 million. This amount is included as “Net loss resulting from early retirement of debt” in the accompanying Condensed Consolidated Income Statements. As of June 30, 2022, $30.1 million of the Convertible Notes remained outstanding. In addition, from July 1, 2022 to the date of this filing, the Company has not received any conversion requests for Convertible Notes and does not anticipate receiving any conversion requests in the near term as the market value of the Convertible Notes exceeds the conversion value of the Convertible Notes. As of June 30, 2022, the if-converted value of the Convertible Notes exceeded the principal amount by It is the Company’s current intent and policy to settle any conversions of notes through a combination of cash and shares. Total interest expense related to the Convertible Debt for the three months ended June 30, 2022 was $1.6 million, which was related to the contractual interest coupon of $1.4 million and $0.2 million of amortization of deferred financing fees. Total interest expense related to the Convertible Debt for the six months ended June 30, 2022 was million related to the amortization of the discount on the liability component and amortization of deferred financing fees. Capped Call Transactions In connection with the offering of the Convertible Notes, the Company entered into privately negotiated convertible note hedge transactions (collectively, the “Capped Call Transactions”). The Capped Call Transactions cover, subject to customary anti-dilution adjustments, the number of shares of the Company’s common stock that initially underlie the Convertible Notes. The Capped Call Transactions are expected generally to reduce the potential dilution and/or offset any cash payments the Company is required to make in excess of the principal amount due upon conversion of the Convertible Notes in the event that the market price of the Company’s common stock is greater than the strike price of the Capped Call Transactions, which was initially $37.325 per share and the initial cap price was $52.255 per share. The initial call and cap prices are subject to adjustments under the terms of the underlying capped call agreements, including various transactions such as the payment of dividends. The number of shares underlying the Capped Call Transactions is As of June 30, 2022, the Capped Call Transaction remain outstanding and have an intrinsic value of $62.1 million. Interest Rate Swaps The Company entered into a series of interest rate swaps to fix a portion of the LIBOR interest payments due under the Term Loan Debt Facility. Through the date of the prepayment, the interest rate swaps qualified for cash flow hedge accounting treatment, and as such, the change in the fair value of the interest rate swaps was recorded on the Company’s Condensed Consolidated Balance Sheets as an asset or liability with the effective portion of the gains or losses reported as a component of accumulated other comprehensive income and the ineffective portion reported in earnings. Due to the Company repaying the majority of the Term Loans in the first quarter of 2022, the interest rate swaps no longer qualify for cash flow hedge accounting and are considered ineffective. As a result, the Company reclassified million from other comprehensive income to expense. Additionally, future changes in value of the interest rate swaps will be recorded to “other operating expense (income), net” in the accompanying Condensed Consolidated Income Statements. The fair value of the interest rate swaps at June 30, 2022 is an asset of $0.8 million, which is recorded within Other noncurrent assets. The Company realized $0.7 million of gains during the three months ended June 30, 2022, related to settlements of the interest rate swaps, which were recorded to interest expense on the Company’s Condensed Consolidated Income Statements. The interest rate swaps are classified as Level 2 within the fair value hierarchy.

Fair Value Measurements	10. The hierarchy of fair value measurements assigns a level to fair value measurements based on the inputs used in the respective valuation techniques. The levels of the hierarchy, as defined below, give the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. ● Level 1 is defined as observable inputs such as quoted prices in active markets for identical assets. Level 1 assets may include available-for-sale securities, U.S. Treasury securities, and coal swaps and futures that are submitted for clearing on the New York Mercantile Exchange. ● Level 2 is defined as observable inputs other than Level 1 prices. These include quoted prices for similar assets or liabilities in an active market, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s Level 2 assets and liabilities may include U.S. government agency securities, coal commodity contracts, and interest rate swaps with fair values derived from quoted prices in over-the-counter markets or from prices received from direct broker quotes. ● Level 3 is defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. These may include the Company’s commodity option contracts (coal and heating oil) valued using modeling techniques, such as Black-Scholes, that require the use of inputs, particularly volatility, that are rarely observable.

For classification purposes, the Company records the net fair value of all the positions with these counterparties as a net asset or liability. Each level in the table above displays the underlying contracts according to their classification in the accompanying Condensed Consolidated Balance Sheet, based on this counterparty netting. The following table summarizes the change in fair values of financial instruments categorized as Level 3.

Earnings per Common Share	11. The Company computes basic net income per share using the weighted average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted average number of common shares and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities may consist of warrants, restricted stock units, and convertible debt. The dilutive effect of outstanding warrants and restricted stock units is reflected in diluted earnings per share by application of the treasury stock method whereas the convertible debt uses the if converted method.

Workers Compensation Expense	12. The Company is liable under the Federal Mine Safety and Health Act of 1969, as subsequently amended, to provide for pneumoconiosis (occupational disease) benefits to eligible employees, former employees and dependents. The Company currently provides for federal claims principally through a self-insurance program. The Company is also liable under various state workers’ compensation statutes for occupational disease benefits. The occupational disease benefit obligation represents the present value of the actuarially computed present and future liabilities for such benefits over the employees’ applicable years of service. In October 2019, the Company filed an application with the Office of Workers’ Compensation Programs (“OWCP”) within the Department of Labor for reauthorization to self-insure federal black lung benefits. In February 2020, the Company received a reply from the OWCP confirming Arch’s status to remain self-insured contingent upon posting additional collateral of of receipt of the letter. The Company is currently appealing the ruling from the OWCP and has received an extension to self-insure during the appeal process. The Company is evaluating alternatives to self-insurance, including the purchase of commercial insurance to cover these claims. In addition, the Company is liable for workers’ compensation benefits for traumatic injuries which are calculated using actuarially-based loss rates, loss development factors and discounted based on a risk free rate. Traumatic workers’ compensation claims are insured with varying retentions/deductibles, or through state-sponsored workers’ compensation programs. Workers’ compensation expense consists of the following components: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 (In thousands) Self-insured occupational disease benefits: Service cost $ 1,497 $ 1,949 $ 2,995 $ 3,898 Interest cost (1) 1,152 1,111 2,304 2,220 Net amortization (1) 157 590 314 1,181 Total occupational disease $ 2,806 $ 3,650 $ 5,613 $ 7,299 Traumatic injury claims and assessments 2,150 1,865 4,206 3,670 Total workers’ compensation expense $ 4,956 $ 5,515 $ 9,819 $ 10,969 (1) In accordance with the adoption of ASU 2017-07, “Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” these costs are recorded within Nonoperating expenses in the Condensed Consolidated Statements of Operations on the line item “Non-service related pension and postretirement benefit costs.”

Commitments and Contingencies	14. Commitments and Contingencies The Company accrues for costs related to contingencies when a loss is probable and the amount is reasonably determinable. Disclosure of contingencies is included in the financial statements when it is at least reasonably possible that a material loss or an additional material loss in excess of amounts already accrued may be incurred. The Company is a party to numerous claims and lawsuits with respect to various matters. The ultimate resolution of any such legal matter could result in outcomes that may be materially different from amounts the Company has accrued for such matters. The Company believes it has recorded adequate reserves for these matters. In the normal course of business, the Company is a party to certain financial instruments with off-balance sheet risk, such as bank letters of credit, performance or surety bonds, and other guarantees and indemnities related to the obligations of affiliated entities which are not reflected in the Company’s Condensed Consolidated Balance Sheets. However, the underlying liabilities that they secure, such as asset retirement obligations, workers’ compensation liabilities, and other obligations, are reflected in the Company’s Condensed Consolidated Balance Sheets. As of June 30, 2022, the Company had outstanding surety bonds with a face amount of $587.3 million to secure various obligations and commitments and $94.8 million of letters of credit under its Securitization and Inventory Facilities used to collateralize certain obligations. The Company had posted million in cash collateral related to various obligations; this amount is recorded within “Noncurrent assets” on the Condensed Consolidated Balance Sheets. As of June 30, 2022, the Company’s reclamation-related obligations of $216.0 million were supported by surety bonds of $498.5 million and $20.0 million in letters of credit used to collateralize certain obligations. The Company has posted million in cash collateral related to reclamation surety bonds. This amount is recorded within “Noncurrent assets” on the Condensed Consolidated Balance Sheets.

Segment Information
Segment Information	15. The Company’s reportable business segments are based on two distinct lines of business, metallurgical and thermal, and may include a number of mine complexes. The Company manages its coal sales by market, not by individual mining complex. Geology, coal transportation routes to customers, and regulatory environments also have a significant impact on the Company’s marketing and operations management. Mining operations are evaluated based on Adjusted EBITDA, per-ton cash operating costs (defined as including all mining costs except depreciation, depletion, amortization, accretion on asset retirement obligations, and pass-through transportation expenses, divided by segment tons sold), and on other non-financial measures, such as safety and environmental performance. Adjusted EBITDA is not a measure of financial performance in accordance with generally accepted accounting principles, and items excluded from Adjusted EBITDA are significant in understanding and assessing the Company’s financial condition. Therefore, Adjusted EBITDA should not be considered in isolation, nor as an alternative to net income, income from operations, cash flows from operations or as a measure of our profitability, liquidity or performance under generally accepted accounting principles. The Company uses Adjusted EBITDA to measure the operating performance of its segments and allocate resources to the segments. Furthermore, analogous measures are used by industry analysts and investors to evaluate the Company’s operating performance. Investors should be aware that the Company’s presentation of Adjusted EBITDA may not be comparable to similarly titled measures used by other companies.

Revenue Recognition	16. ASC 606-10-50-5 requires that entities disclose disaggregated revenue information in categories (such as type of goods or services, geography, market, type of contract, etc.) that depict how the nature, amount, timing, and uncertainty of revenue and cash flow are affected by economic factors. ASC 606-10-55-89 explains that the extent to which an entity’s revenue is disaggregated depends on the facts and circumstances that pertain to the entity’s contracts with customers and that some entities may need to use more than one type of category to meet the objective for disaggregating revenue. In general, the Company’s business segmentation is aligned according to the nature and economic characteristics of its coal and customer relationships and provides meaningful disaggregation of each segment’s results. The Company has further disaggregated revenue between North America and Seaborne revenues which depicts the pricing and contract differences between the two. North America revenue is characterized by contracts with a term of one year or longer and typically the pricing is fixed; whereas Seaborne revenue generally is derived by spot or short term contracts with an index-based pricing mechanism.

The Company has operating and financing leases for mining equipment, office equipment, office space and transloading terminals with remaining lease terms ranging from less than one year to approximately five years. Some of these leases include both lease and non-lease components which are accounted for as a single lease component as the Company has elected the practical expedient to combine these components for all leases. As most of the leases do not provide an implicit rate, the Company calculated the “right-of-use” (“ROU”) assets and lease liabilities using its secured incremental borrowing rate at the lease commencement date. As of June 30, 2022 and December 31, 2021, the Company had the following ROU assets and lease liabilities within the Company’s Condensed Consolidated Balance Sheets: June 30, December 31, 2022 2021 Assets Balance Sheet Classification Operating lease right-of-use assets Other noncurrent assets $ 13,394 $ 14,646 Financing lease right-of-use assets Other noncurrent assets 3,566 4,215 Total Lease Assets $ 16,960 $ 18,861 Liabilities Balance Sheet Classification Financing lease liabilities - current Accrued expenses and other current liabilities $ 946 $ 917 Operating lease liabilities - current Accrued expenses and other current liabilities 2,697 2,606 Financing lease liabilities - long-term Other noncurrent liabilities 3,617 4,097 Operating lease liabilities - long-term Other noncurrent liabilities 11,345 12,713 $ 18,605 $ 20,333 Weighted average remaining lease term in years Operating leases 4.64 5.14 Finance leases 3.25 3.25 Weighted average discount rate Operating leases 5.5% 5.5% Finance leases 6.4% 6.4% Information related to leases was as follows: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 (In thousands) (In thousands) Operating lease information: Operating lease cost $ 831 $ 846 $ 1,661 $ 1,692 Operating cash flows from operating leases 820 826 1,686 1,686 Financing lease information: Financing lease cost $ 393 $ 393 $ 786 $ 786 Operating cash flows from financing leases 303 303 605 606 Future minimum lease payments under non-cancellable leases as of June 30, 2022 were as follows: Operating Finance Year Leases Leases (In thousands) 2022 $ 1,702 $ 606 2023 3,356 1,210 2024 3,200 1,210 2025 3,185 2,111 2026 3,080 — Thereafter 1,533 — Total minimum lease payments $ 16,056 $ 5,137 Less imputed interest (2,014) (574) Total lease liabilities $ 14,042 $ 4,563

Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial reporting and U.S. Securities and Exchange Commission regulations. In the opinion of management, all adjustments, consisting of normal, recurring accruals considered necessary for a fair presentation, have been included. Results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022. These financial statements should be read in conjunction with the audited financial statements and related notes as of and for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the U.S. Securities and Exchange Commission.
Recently Adopted Accounting Guidance	Recently Adopted Accounting Guidance In August 2020, the FASB issued ASU 2020-06 , The if-converted method assumes the conversion of convertible instruments occurs at the beginning of the reporting period and diluted weighted average shares outstanding includes the common shares issuable upon conversion of the convertible instruments. ASU 2020-06 is effective for public business entities, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. The Company adopted ASU 2020-06 on January 1, 2022 under the modified retrospective approach. Upon issuance of the Company's $155.3 million principal amount of 5.25 % convertible senior notes due 2025 (the "Convertible Notes" or “Convertible Debt”) in November 2020, the Company bifurcated the debt and equity components of the Convertible Notes to long-term debt and additional paid-in capital in its consolidated balance sheet. The amount recorded to additional paid-in capital represented a debt discount that was being amortized to interest expense over the life of the Convertible Notes. As part of the adoption of ASU 2020-06, the Company (i) reversed the equity component recorded to additional paid-in capital of $39.2 million, (ii) recorded a cumulative effect of the adoption of ASU 2020-06 of $6.7 million to retained earnings, representing a reversal of the debt discount that was amortized to interest expense, and (iii) an offsetting increase in debt. See Additionally, upon adoption of ASU 2020-06, the treasury stock method utilized by the Company to calculate earnings per share through December 31, 2021 is no longer permitted. Accordingly, the Company has transitioned to the if-converted method utilizing the modified retrospective approach. For the three and six months ended June 30, 2022, under the previous treasury stock method, the diluted earnings per share would have been approximately $19.68 and $33.55 , respectively. As a result of the adoption of ASU 2020-06, diluted earnings per share decreased by Recent Accounting Guidance Issued Not Yet Effective There are no new pronouncements issued but not yet effective expected to have a material impact on the Company’s financial position, results of operations, or liquidity.
