Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Recently Issued Accounting Standards	Basis of Presentation and Recently Issued Accounting Standards The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and are in the form prescribed by the Securities and Exchange Commission (the “SEC”) in instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of The Andersons, Inc. and its wholly owned and controlled subsidiaries (the “Company”). In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of financial position, results of operations and cash flows for the periods indicated. All intercompany accounts and transactions have been eliminated in consolidation. The results in these Condensed Consolidated Financial Statements are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2025. An unaudited Condensed Consolidated Balance Sheet as of September 30, 2024, has been included as the Company operates in several seasonal industries. Effective January 1, 2025, the Company realigned its organizational structure to reflect updates in management reporting resulting in a change in reportable segments. As a result, the former Trade segment was combined with the former Nutrient & Industrial segment in the newly formed Agribusiness segment along with several smaller business lines being moved between the Agribusiness and Renewables segments. All prior period segment information has been recast to conform to the current year presentation. The Condensed Consolidated Balance Sheet data at December 31, 2024, was derived from the audited Consolidated Financial Statements but does not include all disclosures required by GAAP. The accompanying unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in The Andersons, Inc. Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”). The Andersons Marathon Holdings LLC ("TAMH") Equity Acquisition On July 31, 2025, the Company finalized a unit purchase agreement with MPC Investment LLC ("Marathon") to acquire the remaining 49.9% ownership interest in TAMH for cash consideration of $425.0 million. TAMH is comprised of four ethanol production facilities located in Iowa, Indiana, Michigan, and Ohio, with a combined annual production of approximately 500 million gallons. Prior to this transaction, the Company owned a 50.1% interest in TAMH and managed the facilities under a management agreement, providing services such as corn origination, ethanol marketing, and risk management. TAMH had previously been classified as the Company’s sole Variable Interest Entity ("VIE"), with the Company identified as the primary beneficiary. As a result, TAMH’s financial results were already consolidated in the Company’s financial statements. Since the entity was previously consolidated, no additional net assets were acquired in the transaction. Accordingly, the acquisition was treated as an equity transaction, impacting Additional paid-in capital, Noncontrolling interests, and Deferred income taxes on the Company’s Condensed Consolidated Balance Sheets. Following the closing of the transaction, the Company now owns 100% of TAMH. The entity was renamed The Andersons Renewables, LLC and is no longer considered a VIE. Additionally, Marathon, which had been the primary counterparty in related party transactions, is no longer classified as a related party. Any remaining related party activity is considered de minimis. Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which improves the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This guidance will be effective for the annual periods beginning with the year ended December 31, 2025. Early adoption is permitted. Upon adoption, the guidance can be applied prospectively or retrospectively. Management does not expect the adoption of this guidance to have a material impact on the Consolidated Financial Statements. In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40), which requires the disaggregated disclosure of specific expense categories, including purchases of inventory, employee compensation, depreciation, and amortization, within relevant income statement captions. This ASU also requires disclosure of the total amount of selling expenses along with the definition of selling expenses. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Adoption of this ASU can either be applied prospectively to consolidated financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the consolidated financial statements. Early adoption is also permitted. The adoption of the amended guidance will result in expanded disclosures in the Company’s footnotes but is not expected to have a material impact on the Company's Consolidated Financial Statements.
