Detailed Narrative
Strategic Growth Engines & AI Integration
Grainger made significant progress across its five strategic growth engines in 2025, including merchandising, marketing, seller coverage, seller effectiveness, and value-added services like KeepStock. Merchandising efforts led to a net assortment growth of over 85,000 SKUs, the largest in nearly a decade for the High-Touch segment, with expansion into data center and factory automation products. The company added 110 new sellers in 2025, bringing the total program expansion to over 300 sellers since 2022. AI and machine learning are increasingly leveraged to optimize marketing investment, improve seller effectiveness through a new insights platform, and enhance customer experience in KeepStock.
Endless Assortment Segment Momentum
The Endless Assortment segment demonstrated strong performance in 2025, with daily organic constant currency sales up 15.6%. Zoro U.S. reaccelerated sales growth into the high teens for the full year by focusing on improved repeat purchase rates, optimizing assortment for delivery times, and enhancing direct marketing capabilities. MonotaRO continued its strong execution, achieving 25% growth with enterprise customers and expanding distribution capabilities with same-day shipping to new regions, alongside planning for a new highly-automated DC in Mito.
Supply Chain Capacity Investments
Grainger is extending its industry-leading distribution network with significant investments in new facilities. The Northwest DC near Portland is set to begin full outbound operations later in 2026, improving service and reducing transportation costs. The Houston distribution center expects inbound operations to start in the second half of 2027, with outbound following a few quarters later. In Japan, MonotaRO's new highly-automated Mito DC, scheduled to open in 2028, will nearly double its shipping capacity in the country, reinforcing customer fulfillment capabilities.
Transition to Multifactor MRO Market Model
Grainger has transitioned from a single-factor to a multifactor MRO market model to measure its outgrowth progress, citing a sustained period of dislocation between the single-factor model and on-the-ground customer observations. The new model, developed after testing over 1,000 economic indicators, incorporates various supply and demand factors like net core capital good shipments, import/export dynamics, and end-user activity. This comprehensive approach is believed to more accurately reflect market performance, especially during economic disruptions, and showed a stronger correlation to underlying MRO product consumption data.
Tariff Dynamics and Price/Cost Management
The company continued to navigate shifting tariff dynamics and cost pressures in 2025. Modest price increases were implemented in November 2025, building on earlier actions in May and September, to offset tariff-related costs. Further price adjustments were made in January 2026 to catch up📎 on delayed tariff inflation and annual supplier cost increases, net of a partial rollback on certain Chinese tariffs. Management aims for price/cost neutrality over time⏳, despite LIFO inventory valuation headwinds, and remains agile in responding to the fluid tariff situation.
