Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited Condensed Consolidated Financial Statements have been prepared by the management of MSC Industrial Direct Co., Inc. (together with its wholly owned subsidiaries and entities in which it maintains a controlling financial interest, “MSC Industrial” or the “Company”) and in the opinion of management include all normal recurring adjustments necessary to present fairly the Company’s financial position as of February 28, 2026 and August 30, 2025, results of operations for the thirteen and twenty-six weeks ended February 28, 2026 and March 1, 2025, and cash flows for the twenty-six weeks ended February 28, 2026 and March 1, 2025. The financial information as of August 30, 2025 was derived from the Company’s audited Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended August 30, 2025. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations of the SEC. The Company, however, believes that the disclosures contained in this Report comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for a Quarterly Report on Form 10-Q and are adequate to make the information presented not misleading. The unaudited Condensed Consolidated Financial Statements and these Notes to Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended August 30, 2025. Fiscal Year The Company operates on a 52/53-week fiscal year ending on the Saturday closest to August 31st of each year. References to “fiscal year 2026” refer to the period from August 31, 2025 to August 29, 2026, which is a 52-week fiscal year. References to “fiscal year 2025” refer to the period from September 1, 2024 to August 30, 2025, which is a 52-week fiscal year. The fiscal quarters ended February 28, 2026 and March 1, 2025 refer to the thirteen weeks ended as of those dates. Principles of Consolidation The unaudited Condensed Consolidated Financial Statements include the accounts of MSC Industrial Direct Co., Inc., its wholly owned subsidiaries and entities in which it maintains a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. Accounting Standards Not Yet Adopted In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures to enhance the transparency and decision usefulness of income tax disclosures. The ASU primarily enhances and expands both the income tax rate reconciliation disclosure and the income taxes paid disclosure. The ASU is effective for annual periods beginning after December 15, 2024 (MSC’s fiscal year 2026) on a prospective basis. The adoption of this guidance is not expected to affect the Company’s Consolidated Financial Statements and the Company is currently evaluating the standard to determine the impact of adoption on its 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. The ASU requires public entities to include more detailed disclosures about specific categories of expenses such as inventory purchases, employee compensation, depreciation, amortization and selling costs within the notes to the financial statements. The ASU is effective for fiscal year periods beginning after December 15, 2026 (MSC’s fiscal year 2028) and interim periods within fiscal years beginning after December 15, 2027 (MSC’s first quarter of fiscal year 2029), with early adoption permitted. The adoption of this guidance is not expected to affect the Company’s Consolidated Financial Statements and the Company is currently evaluating the standard to determine the impact of adoption on its disclosures. In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Topic 350-40): Targeted Improvements to Accounting for Internal-Use Software. The ASU primarily amends guidance for accounting and disclosure of internal-use software, including clarifying the requirements for capitalizing costs and removal of references to the stage-based approach for capitalizing costs. The ASU is effective for annual periods beginning after December 15, 2027 (MSC’s fiscal year 2029) on a prospective, retrospective or modified prospective approach. The Company is currently evaluating the standard to determine the impact of adoption on its Consolidated Financial Statements and disclosures. Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are either not applicable or are not expected to have a material impact on the Consolidated Financial Statements.
