Business Description

Note – Information in this section is as of year end unless otherwise noted. The year end is December 31, 2025 unless additional years are included or noted. Overview Fastenal began as a partnership in 1967, and was incorporated under the laws of Minnesota in 1968. We opened our first branch in 1967 in Winona, Minnesota, a city with a population today of approximately 26,000. We began with a marketing strategy of supplying threaded fasteners to customers through a branch network in small, medium, and, in subsequent years, large cities. Over time, how and where we engage our customers has expanded and evolved. Today we sell a broader range of industrial and construction supplies spanning more than nine major product lines through a global network of locations utilizing diverse technologies such as vending devices, bin stock devices, and eBusiness. The large majority of our transactions are business-to-business. We provide additional descriptions of our product lines and market channels later in this document. At the end of 2025, we had 1,595 branch locations in 25 countries supported by 15 distribution centers in North America, with 12 in the United States (U.S.), two in Canada, and one in Mexico; two in Asia; and two in Europe, and we employed 24,489 people. We believe our success can be attributed to the high quality of our employees and their convenient proximity to our customers, and our ability to offer customers a full range of products and services to reduce their total cost of procurement. Channels to Market Historically, our growth was primarily measured by our physical locations count. Today, we emphasize optimizing our footprint and tailoring service models to customer sites based on their size and potential for growth. Physical location openings and adjustments reflect local market conditions and strategic priorities rather than a uniform expansion approach. We engage customers primarily through physical selling locations that deliver Fastenal service and solutions at or near customer operations called sites (Sites). Starting in 2025, we have disclosed Sites information instead of public branches and customer-dedicated Onsites. These Sites are distinct locations of our customers' operations where we maintain inventory tailored to local demand, supported by our regional distribution networks. Each Site may incorporate one or more service models, including Fastenal Managed Inventory (FMI) programs (FASTStock, FASTBin, FASTVend), integrated supply programs, eBusiness capabilities, and advanced manufacturing services. These models are designed to improve product availability, automate replenishment, and reduce procurement costs for customers. Customer Sites and Sales Segmentation Our strategy prioritizes customer sites with monthly sales potential of $50,000 or more. Segmentation by spend level provides insight into the scale and potential of customer relationships served through our network.…
