Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying Unaudited Condensed Consolidated Financial Statements include Genesis Energy, L.P. and its subsidiaries. On February 28, 2025, we completed the sale of our trona and trona-based exploring, mining, processing, producing, marketing, logistics and selling business based in Wyoming (the “Alkali Business”) for a gross purchase price of approximately $1.425 billion. We determined that the exit of the Alkali Business and its operations in Wyoming represented a strategic and geographic shift that met the criteria for discontinued operations (see Note 4 for further discussion). Accordingly, we have separately reported the operations from the Alkali Business in the Unaudited Condensed Consolidated Statements of Operations and the related assets and liabilities of the Alkali Business in the Unaudited Condensed Consolidated Balance Sheets as discontinued operations. These changes have been applied retrospectively to all periods presented. The disclosures included within the accompanying notes to the Unaudited Condensed Consolidated Financial Statements are representative of our continuing operations. Our results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the fiscal year. The Unaudited Condensed Consolidated Financial Statements included herein have been prepared by us pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they reflect all adjustments (which consist solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the financial results for interim periods. Certain information and notes normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. However, we believe that the disclosures are adequate to make the information presented not misleading when read in conjunction with the information contained in the periodic reports we file with the SEC pursuant to the Securities Exchange Act of 1934, including the Consolidated Financial Statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024 (our “Annual Report”). Except for per unit amounts, or as noted within the context of each footnote disclosure, the dollar amounts presented in the tabular data within these footnote disclosures are stated in thousands of dollars.
