| Basis of Presentation | Basis of Presentation The accompanying condensed consolidated financial statements include the accounts and operations of the ARLP Partnership and present our financial position as of June 30, 2026 and December 31, 2025, the results of our operations and comprehensive income for the three and six months ended June 30, 2026 and 2025 and cash flows for the six months ended June 30, 2026 and 2025. All intercompany transactions and accounts have been eliminated. These condensed consolidated financial statements and notes are prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim reporting and do not include all the information normally included with financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) of the United States. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025. These condensed consolidated financial statements and notes are unaudited. However, in the opinion of management, these condensed consolidated financial statements reflect all normal recurring adjustments necessary for a fair presentation of the results for the periods presented. Results for interim periods are not necessarily indicative of results to be expected for the full year ending December 31, 2026. |

| Use of Estimates | Use of Estimates The preparation of the ARLP Partnership’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in our condensed consolidated financial statements. Actual results could differ from those estimates. |

| New Accounting Standards Issued and Not Yet Adopted | New Accounting Standards Issued and Not Yet Adopted In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”). ASU 2024-03 requires the disclosure of additional information about specific expense categories in the notes to the financial statements to provide enhanced transparency into the nature and function of expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, on a prospective basis, with early adoption permitted. We continue evaluation of the impact of ASU 2024-03 on our results of operations, cash flows, financial condition and related disclosures including ongoing research as well as assessing our ability to accurately generate the information required for disclosure. In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). ASU 2025-06 improves the accounting for software development costs by removing references to software development stages so that the accounting is neutral to different software development methods. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027 and interim periods within those fiscal years, with early adoption permitted. ASU 2025-06 can be applied on a prospective basis, a modified basis for in-process projects or a retrospective basis. We are evaluating the impact of ASU 2025-06 on our results of operations, cash flows, financial condition and related disclosures.
