GWW vs GM Comparison

Founded in 1927, W.W. Grainger originally distributed various motors via a mail-order catalog. Over the course of the 20th century, the firm expanded into new industrial product categories and launched its first digital catalog in 1995. Today, the company organizes itself into two segments focused on different customer bases. Its larger segment, high-touch solutions, offers a vast array of maintenance, repair, and operations, or MRO, supplies and bespoke inventory management services to larger businesses. Its smaller segment, endless assortment, operates two online platforms, Zoro and MonotaRO, that offer comprehensive catalogs of MRO supplies to smaller businesses. Grainger has operations throughout the world but primarily generates sales within the US.

General Motors Co. emerged from the bankruptcy of General Motors Corp. (old GM) in July 2009. GM has eight brands and operates under three segments: GM North America, GM International, and GM Financial. The United States now has four brands instead of eight under old GM. The company regained its US market share leadership in 2022, after losing it to Toyota due to the chip shortage in 2021. 2025 US share was 17.4%, up 60 basis points from 2024. The Cruise autonomous vehicle arm, which GM now owns outright, previously operated driverless geofenced AV robotaxi services in San Francisco and other cities, but after a 2023 accident, GM decided that it will focus on personal AVs. GM Financial became the company's captive finance arm in 2010 via the purchase of AmeriCredit.
