Accounting Standards Not Yet Adopted
In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“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 Balance Sheets, Statements of Income, or Statements of Cash Flows 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 Balance Sheets, Statements of Income, or Statements of Cash Flows and the Company is currently evaluating the standard to determine the impact of adoption on its 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.
Recently Adopted Accounting Standards
In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU requires entities, including those with a single reporting segment, to disclose significant segment expenses that are regularly provided to the chief operating decision maker, among other provisions. The ASU is effective for fiscal year periods beginning after December 15, 2023 (MSC’s fiscal year 2025) and interim periods within fiscal years beginning after December 15, 2024 (MSC’s first quarter of fiscal year 2026), with early adoption permitted. The Company adopted this guidance effective for the fiscal year ended August 30, 2025. The adoption of ASU 2023-07 resulted in changes to the Company’s disclosures, including comparative information for all years presented, but had no impact on the Company’s Consolidated Financial Statements. See Note 16, “Segment Reporting” for additional information on segments.

About New Standards Disclosures

New accounting standards disclosures describe recently adopted pronouncements and those not yet effective, along with management's assessment of their expected impact. This section provides an early warning system for upcoming changes to how a company reports its financial results, often years before the new rules take effect.

Key signals: when management describes a not-yet-adopted standard's impact as "material" or "still being evaluated," it signals potential significant changes to reported metrics upon adoption. Watch for standards that affect a company's core operations — for example, revenue recognition changes for software companies or lease accounting changes for retailers with large store footprints. The transition method chosen (full retrospective versus modified retrospective) affects comparability with prior periods. Companies that delay adoption to the latest permitted date may be struggling with implementation complexity. Compare the disclosed impact assessments against peers in the same industry to gauge whether management's expectations are reasonable.
