(1)Customer industry results for the three months ended March 31, 2026 and 2025 primarily use the North American Industry Classification System (NAICS). As customers' businesses evolve, industry classifications may change. When these changes occur, Grainger does not recast the customer classification for prior periods as the industry used in the prior period was appropriate at the point-in-time. As a result, year-over-year changes may be impacted.
(2)Total Company includes other businesses, which included the Cromwell business through the date of divestiture in the fourth quarter of 2025. For further details on the sale, see Note 2 of the Notes to Consolidated Financial Statements in Part II, Item 8: Financial Statements and Supplementary Data in the Company’s 2025 Form 10-K. Other businesses accounted for approximately 2% of total Company revenue for the three months ended March 31, 2025.
(3)Other primarily includes revenue from industries and customers that are not material individually, including hospitality, restaurants, property management and natural resources.
