Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The interim condensed consolidated financial statements have been prepared in accordance with the U.S. Securities and Exchange Commission (“SEC”) instructions to Quarterly Reports on Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting. The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the interim condensed consolidated financial statements and accompanying notes. Actual amounts could differ from those estimates. The fiscal year of Greif, Inc. and its subsidiaries (the “Company”) begins on October 1 and ends on September 30 of the following year. Any references to years relates to the fiscal year ended in that year, unless otherwise stated. The information filed herein reflects all adjustments that are, in the opinion of management, necessary for a fair presentation of the interim condensed consolidated balance sheet as of December 31, 2025 and the condensed consolidated balance sheet as of September 30, 2025, the interim condensed consolidated statements of income, comprehensive income and changes in shareholders’ equity for the three months ended December 31, 2025 and 2024 and the interim condensed consolidated statements of cash flows for the three months ended December 31, 2025 and 2024 of the Company. The interim condensed consolidated financial statements include the accounts of Greif, Inc., all wholly-owned and consolidated subsidiaries and investments in limited liability companies, partnerships and joint ventures in which it has controlling influence or is the primary beneficiary. Non-majority owned entities include investments in limited liability companies, partnerships and joint ventures in which the Company does not have controlling interest and are accounted for using either the equity or cost method, as appropriate. The unaudited interim condensed consolidated financial statements included in this Quarterly Report on Form 10-Q (this “Form 10-Q”) should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Transition Report on Form 10-KT for its fiscal year ended September 30, 2025 (the “2025 Form 10-KT”). Change in Presentation Discontinued Operations On June 30, 2025, the Company entered into a definitive agreement to sell its containerboard business, including the CorrChoice sheet feeder system (the “Containerboard Business”), and the equity interests in the Company’s subsidiaries that directly owned the Containerboard Business on the date of closing. The transaction was completed effective as of August 31, 2025 (the “Containerboard Divestiture”). The Containerboard Divestiture qualifies as discontinued operations because it represents a strategic shift that will have a major impact on the Company’s operations and financial results. As a result, the Containerboard Business is presented as discontinued operations beginning in the third quarter of 2025. See Note 2 to the interim condensed consolidated financial statements for additional disclosures. The Company has reclassified the financial results of the Containerboard Business to discontinued operations, net of tax, in the Condensed Consolidated Statements of Income for all periods presented. Cash flows from the Company’s discontinued operations are not presented separately in the Condensed Consolidated Statements of Cash Flows for all periods presented. Unless otherwise noted, the discussion in these Notes to the interim condensed consolidated financial statement relates only to continuing operations. Recast of Certain Prior Period Information Effective October 1, 2025, the Company changed the name of its Integrated Solutions reportable segment to Innovative Closure Solutions. The Company is involved in the purchase and sale of recycled fiber and the production and sale of adhesives used in the Company’s paperboard products. Both of these products were previously reported under the Integrated Solutions reportable segment (now the Innovative Closure Solutions reportable segment), and effective October 1, 2025, these products are reported under the Sustainable Fiber Solutions reportable segment. The Company is also involved in the production and sale of complimentary packaging products and services such as paints, linings and filling that are related to the Company’s steel products. Both of these products and services were previously reported under the Integrated Solutions reportable segment (now the Innovative Closure Solutions reportable segment), and effective October 1, 2025, these products and services are reported under the Durable Metal Solutions reportable segment. These adjustments position each business within its respective place in the integrated value chain and reinforce a clear emphasis on closure systems within the Innovative Closure Solutions reportable segment. This internal re-alignment has resulted in prior period segment information being recast for the 2025 fiscal year. Effective October 1, 2025, the Company’s fiscal year was changed to begin on October 1 (rather than November 1), and ends on September 30 (rather than October 31) of the following year, and each fiscal quarter end was changed to align with the fiscal year end change with the first fiscal quarter ended December 31, 2025. This fiscal quarter re-alignment has resulted in prior period quarterly information being recast for the 2025 fiscal year. The prior reported fiscal quarters for the 2025 fiscal year ended on January 31, 2025, April 30, 2025, July 31, 2025 and September 30, 2025 (a two-month period). Newly Adopted Accounting Standards In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which is intended to improve reportable segment disclosure requirements. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted this ASU on November 1, 2024. The adoption of this guidance did not have a material impact on the Company's financial position, results of operations, comprehensive income, cash flows or disclosures. Recently Issued Accounting Standards 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,” which is intended to modernize the accounting for internal-use software costs. This ASU is effective for fiscal years beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. The effective date for the Company to adopt this ASU is for the fiscal year and interim periods beginning October 1, 2028. The Company is in the process of determining the potential impact of adopting this guidance on its financial position, results of operations, comprehensive income, cash flow and disclosures. In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses,” which is intended to improve disclosures related to certain of the Company’s income statement expenses. This ASU is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The effective date for the Company to adopt this ASU is for the fiscal year and interim periods beginning October 1, 2027 and October 1, 2028 respectively. The Company is in the process of determining the potential impact of adopting this guidance on its financial position, results of operations, comprehensive income, cash flow and disclosures. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Tax Disclosures,” which is intended to improve the effectiveness of income tax disclosures. This ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The effective date for the Company to adopt this ASU is for the fiscal year beginning October 1, 2025. The Company is in the process of determining the potential impact of adopting this guidance on its financial position, results of operations, comprehensive income, cash flow and disclosures.
