**DOCUMENTS INCORPORATED BY REFERENCE**

Portions of our Proxy Statement relating to our 2026 annual meeting of shareholders (Proxy Statement) are incorporated by reference into Part III of this Annual Report on Form 10-K where indicated. Our Proxy Statement will be filed with the U.S. Securities and Exchange Commission within 120 days after the end of the fiscal year to which this report relates.

**FORWARD-LOOKING STATEMENTS**

Certain statements contained in this Annual Report on Form 10-K, or in our other reports and other written and oral statements we made from time to time, do not relate strictly to historical or current facts. As such, they are considered 'forward-looking statements' that provide current expectations or forecasts of future events. These forward-looking statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such statements can be identified by the use of terminology such as anticipate, believe, should, estimate, expect, intend, may, will, plan, goal, project, hope, trend, target, opportunity, and similar words or expressions, or by references to typical outcomes. Any statement that is not a purely historical fact, including estimates, projections, trends, and the outcome of events that have not yet occurred, is a forward-looking statement. Our forward-looking statements generally relate to our expectations regarding the business environment in which we operate, our projections of future performance and opportunities for growth based on potential market opportunities, our perceived marketplace opportunities, our strategies, goals, mission and vision, historical sequential trends and sales changes, and our expectations about matters including capital expenditures, tax rates, inventory levels, liquidity, declaration and payment of dividends, liabilities from tax positions, the performance of our fastener business in comparison to our non-fastener business, openings and closing of branch locations and new machine equivalent units for Fastenal Managed Inventory (FMI) (including bin stock and industrial vending) and the competitive advantages they offer, our digital solutions and other product offerings (including new product lines), contract accounts as a percentage of overall sales, the advantages of our integrated physical and virtual model, growth in safety products as a percentage of product sales, the amount of FMI sales that we may be able to service through local inventory fulfillment terminals, and the ability of our competitors to replicate our distribution capabilities. You should understand that forward-looking statements involve a variety of risks and uncertainties, known and unknown, and may be affected by inaccurate assumptions. Consequently, no forward-looking statement can be guaranteed and actual results may vary materially. Factors that could cause our actual results to differ from those discussed in the forward-looking statements include, but are not limited to, economic downturns (including economic downturns as a result of global pandemics), weakness in the manufacturing or commercial construction industries or any of our end markets, competitive pressure on selling prices, changes in trade policies or tariffs, changes in our current mix of products, customers, or geographic locations, changes in our average branch size, changes in our purchasing patterns, changes in customer needs, changes in fuel or commodity prices, product and transportation inflation, inclement weather, changes in foreign currency exchange rates, difficulty in adapting our business model to different foreign business environments, failure to accurately predict the market potential of our business strategies, the introduction or expansion of new business strategies, increased competition (including with respect to our FMI), difficulty in maintaining installation quality as our industrial vending business expands, the failure to meet our goals and expectations regarding branch openings, branch closings, or expansion of our FMI offering, the failure to realize expected benefits from the completion of our strategic rationalization, changes in the implementation objectives of our business strategies, difficulty in hiring, relocating, training, or retaining qualified personnel, difficulty in controlling operating expenses, difficulty in collecting receivables or accurately predicting future inventory needs, changes in sales trends, changes in supplier production lead times, short-term inefficiencies in our supply chain may not normalize or result in certain warehousing customer growth, changes in our cash position or our need to make capital expenditures, credit market volatility and increases in interest rates, changes in tax law or the impact of discrete items on future tax rates, changes in the availability or price of commercial real estate, changes in the nature, price, or availability of distribution, supply chain, or other technology (including software licensed from third parties) and services related to that technology, difficulty in obtaining continued business from new safety product customers and the acceptance by customers of any new product lines, cybersecurity incidents, potential liability and reputational damage that can arise if our products are defective, and other risks and uncertainties detailed in this Annual Report on Form 10-K under the heading 'Item 1A. Risk Factors'. Each forward-looking statement speaks only as of the date on which such statement is made, and we undertake no obligation to update any such statement to reflect events or circumstances arising after such date.

**PRESENTATION OF DOLLAR AMOUNTS**

All dollar amounts in this Annual Report on Form 10-K are presented in millions, except for share and per share amounts or where otherwise noted. Throughout this document, percentage and dollar change calculations, which are based on non-rounded dollar values, may not be able to be recalculated using the dollar values in this document due to the rounding of those dollar values. References to daily sales rate (DSR) change may reflect either growth (positive) or contraction (negative) for the applicable period.

On April 23, 2025, Fastenal Company (together with our subsidiaries, hereinafter referred to as 'Fastenal,' 'the Company,' 'we,' 'our,' or 'us') announced a two-for-one stock split of its outstanding common stock. Holders of the Company's common stock, par value $0.01 per share, at the close of business on May 5, 2025, received one additional share of common stock for every share of common stock they owned. The stock split took effect at the close of business on May 21, 2025. All historical common stock share, per share information, stock option awards, and stockholders' equity balances for all periods presented in the accompanying Consolidated Financial Statements and Notes thereto in this Annual Report on Form 10-K have been retroactively adjusted to reflect the two-for-one stock split.

**PART I**

**ITEM 1. BUSINESS**

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. The following table summarizes customer Sites averaged by monthly spend band and related monthly sales metrics with the final metric representing the count of individual unique sites that did business throughout the year.

**Our Business Tools**

**Fastenal Managed Inventory (FMI**<sup>®</sup>**)**

Over time, we have invested in and developed various technologies that allow us to put physical product closer to the point of use in a customer location, increase the visibility of a customer's supply chain (to the customer as well as our personnel), and/or improve the ability to monitor or control usage. While there are isolated exceptions, these technologies are not themselves channels to the market but rather are utilized by our selling locations to enhance service to our customers. Collectively, these tools comprise our FMI Technology suite. We believe our fully integrated distribution network allows us to manage the supply chain for all sizes of customers. FMI programs tend to generate a higher frequency of business transactions and, coupled with our fully integrated distribution network, foster a strong relationship with customers.

**Industrial vending (FASTVend**<sup>®</sup>**)** was introduced in 2008 to provide our customers with improved product monitoring and control. Benefits include reduced consumption, reduced purchase orders, reduced product handling, and 24-hour product availability. We believe that we have a market advantage by virtue of our extensive network of inventory and local personnel. For these reasons, the initiative began to gain significant traction in 2011, and we finished 2025 with approximately 124,000 FASTVend devices in the field. We believe industrial vending has proven its effectiveness in strengthening our relationships with customers, and helped to streamline the supply chain where it has been utilized. We also believe there remains considerable room to grow our current installed base of devices before it begins to approach the number of units we believe the market can support. We estimate the market could support as many as 1.7 million vending units and, as a result, we anticipate continued growth in installed devices over time.

Our industrial vending portfolio consists of 21 different vending devices, with 16 of these being in either a helix or locker format. Our most utilized models include the helix-based FAST 5000 and our 12- and 18-door lockers; combined, these comprise approximately 63% of our installed base of devices. These are either configurable or are available in multiple configurations to accommodate the various sizes and forms of products that will be dispensed to match the unique needs of our customers. Target monthly sales per device typically range from under $1,000 to in excess of $3,000, with our flagship FAST 5000 device having a targeted monthly throughput of $2,000.

**Bin stock (FASTStock**<sup>℠</sup> **and FASTBin**<sup>®</sup>**)** programs, where product is held in bins in a customer facility, are similar to our vending business in that it involves moving product closer to the point of customer use within their facilities. Such programs have existed in the industrial supply industry for a considerable time, with open bins being clustered in a racking system, each of which holds direct fasteners, indirect fasteners, and/or non-fastener products that are consumed in the customers' operations. Historically, these bins were simply plastic and metal containers that held product and were visually inspected by our customers or Fastenal personnel to determine replenishment need. These bins in some cases are organized and labeled into customized digital plan-o-grams, which we call FASTStock and allow for the scanning of product when it is at a minimum desired level. However, in 2019 we introduced our FASTBin technology. FASTBin is the evolution of FASTStock into a set of electronic inventory management solutions that automate process controls by providing 24/7 continuous inventory monitoring, real-time inventory visibility, and automatic replenishment of bin stock parts.

These technologies come in four forms: (1) scales that utilize a high-precision weight sensor system to measure the exact quantity on hand in real time, notifying Fastenal to replenish when inventory hits an established minimum; (2) infrared (IR) that uses IR sensors lining individual bins to provide real-time visibility of approximate quantity and inventory values, notifying Fastenal to replenish when inventory hits an established minimum threshold; (3) RFID, which is a Kanban system that utilizes RFID tags so that when an empty bin is removed from the rack and placed in a replenishment zone (also part of the same racking system), a notification is sent to Fastenal to refill the order; and (4) FASTClick, which is an electronic button utilized on products or in locations that do not lend themselves to a vending- or bin-based solution that allows a customer to signal they would like a replenishment activity without the need of a Fastenal representative. These technologies provide superior monitoring capabilities and immediate visibility to consumption changes, allowing for a lean supply chain, reducing risk of stock-outs, and providing a more efficient labor model for both the customer and the supplier.

Our weighted FMI measure combines signings and installations of FASTBin and FASTVend in a standardized machine equivalent unit (MEU) based on the expected output of each type of device. We do not include FASTStock in this measurement because scanned stocking locations can take many forms, such as bins, shelves, cabinets, pallets, etc., that cannot be converted into a standardized MEU. This conversion takes the targeted monthly throughput of each FMI device signed or installed and compares it to the $2,000 target monthly throughput of our FAST 5000 vending device. For example, an RFID enclosure, with target monthly sales of $2,000 would be counted as '1.00' machine equivalent ($2,000/$2,000 = 1.00). An infrared bin, with target monthly sales of $40, would be counted as '0.02' machine equivalent ($40/$2,000 = 0.02).

The table below summarizes the signings and installations of, and sales through, our FMI devices.

**Digital Solutions**

We also invest in digital solutions that aim to deliver strategic value for our customers, leverage local inventory for same-day solutions, and provide efficient service. While there is a transactional element to our digital services, many of the solutions we invest in are intended to add value to customers by illuminating various elements of their supply chain. In many cases, this provides insights that allow us to migrate transactional, 'non-sticky' (and traditionally high cost) online spend into a 'sticky' managed setting (such as our FMI programs). These solutions take many forms:

1) *Transactional*. Our eBusiness includes eProcurement activities, which are integrated transactions, including electronic data interchange (EDI), and eCommerce (transactional website sales), which provide a means for our customers to effectively and efficiently procure indirect and unplanned spend. While there is a retail component to our transactional digital services, most of the sales attributable to this is with our traditional customer base, nearly all of which purchase digitally as a supplement to other channels and tools it utilizes with Fastenal. We attribute the sales generated from a customer location through our transactional platforms to the location traditionally servicing this customer location.

2) *Analytics*. Data analytics provide customers with detailed insights into their business operations. FAST360° offers a comprehensive view of inventory and spending, allowing users to visualize product organization and analyze spending trends. FAST360° Analytics uses Microsoft Power BI to offer stakeholders visualization tools for analyzing spend, supply channels, and cost savings. FAST360° acts as the bridge between our fulfillment operations and a customer's view into our managed service model, and provides our customers with one central source of information. These platforms empower users to make data-driven decisions, optimize operations, and improve efficiency by providing actionable insights into Fastenal-managed inventory and spending. By incorporating visual representations of complex data into standardized and tailored reporting templates, the team collaborates with Fastenal's customers and business leaders to turn insights into action.

3) *Digital Visibility*. Our digital capabilities are intended to produce operational efficiencies for our customers and ourselves and/or to deliver strategic value by illuminating customer supply chain operations where the employee works. For instance, we have developed, and continue to develop, 'Mobility' applications (Apps), one example of which is our FASTScan and BinStock App, which provides several benefits. It provides easy, real-time information pertaining to a customer's local inventory position within their point-of-use devices. Other applications are assisted by artificial intelligence (AI) to analyze customer usage data to recommend optimized parts and quantity for specific devices, which improves customer inventories while reducing the risk of stock-outs. Our Vending App moves our fulfillment process from a vending device-based keypad function to a tablet or scanning interaction, which improves the restock process (reduced risk of product outages), reducing time consumed (greater efficiency) while improving accuracy (improved quality assurance). We will continue to build out our suite of Apps.

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

Visibility is also achieved through EDI connectivity between our system and our customers' procurement systems – whether a direct integration into their Enterprise Resource Planning system or through a third-party procurement network or marketplace. These solutions provide a system-to-system exchange of electronic procurement documents (such as purchase orders, advanced shipping notices, and invoices for direct and indirect spend). Our eProcurement Solutions provide a bridge between our managed replenishment activity and our customers' procurement systems – creating an efficient, accurate and streamlined procure-to-pay process.

4.) *Crib Management*. We host FASTCrib, a cloud-based software tool designed to provide customers with visibility and control of their entire supply chain. It is an integrated platform that maintains customer-specific product catalogs, provides control and tracking of inventory levels, streamlines and consolidates procurement processes, and enables rich visualization and reporting in an environment with robust user controls. It also has asset tracking features and integrates with portions of our FMI suite. FASTCrib creates a one-stop, just-in-time supply chain management capability for all of the products and services consumed by our customers, whether provided directly by Fastenal or other vendors.

**Digital Footprint**

Our digital products and services are comprised of sales through FMI (FASTStock, FASTBin, and FASTVend) plus that proportion of our eBusiness sales that do not represent billings of FMI services (collectively, our Digital Footprint). We believe the data that is created through our digital capabilities enhances product visibility, traceability, and control that reduces risk in operations and creates ordering and fulfillment efficiencies for both us and our customers. FAST360 is the tool Fastenal uses to effectively and efficiently present these data analytics to both customers and our employees to improve the ability for data driven decision making. As a result, we believe our opportunity to grow our business will be enhanced through the continued development and expansion of our digital capabilities. Our Digital Footprint represented 61.4% of sales in 2025.

We believe the combination of our broad product offering, physical presence on a global scale, and toolbox of services, specialists, and digital capabilities, produces a customer engagement model that is difficult for large and small competitors to replicate. This is consistent with our strategy and offers significant value by providing differentiated and difficult to displace service. We also believe it differentiates us when compared to web purchasing models as an independent sales channel. We expect to continue to build out and develop our digital solutions over time. Our greatest opportunity lies with the deployment of efficient and effective supply chain programs. We are focused on addressing the four key components: people, products, processes, and technology, to support this model.

**Distribution Network**

We operate 15 regional distribution centers in North America: 12 in the U.S., two in Canada, and one in Mexico. We also operate two distribution centers in Asia and two distribution centers in Europe. These distribution centers give us approximately 5.3 million square feet of distribution capacity. Additional details on these locations can be found within the 'Item 2. Properties' section of this Form 10-K. These distribution centers are located so as to permit deliveries of two to five times per week to our selling locations using our trucks and overnight delivery by surface common carrier, with approximately 79% of our North American selling locations receiving service four to five times per week. The distribution centers in Indiana and Kansas also serve as 'master' hubs, with those in California and North Carolina serving as 'secondary' hubs to support the needs of the selling locations in their geographic regions, as well as to provide a broader selection of products for the selling locations serviced by the other distribution centers.

We currently operate 12 of our North American distribution centers with automated storage and retrieval systems (ASRS). These distribution centers operate with greater speed and efficiency, and currently handle approximately 96% of our picking activity. We expect to invest in additional automation technologies, expand existing distribution facilities, and/or add new distribution centers over time as our scale and the number of our selling locations increases.

We also utilize a network of Local Inventory Fulfillment Terminals (LIFTs) which reside within our existing distribution centers and are intended to support areas that have a dense population of FMI devices. Traditionally, branch personnel were solely responsible for stocking and packaging FMI-related inventory, delivering to a customer's location, and refilling the customer's devices. As our sales through FMI devices have grown, this approach resulted in redundant inventory in a territory and a greater proportion of our sales personnel's time being spent on non-sales activities, an issue we are mitigating through LIFTs. We primarily utilize a 'drop-and-deliver' model wherein a LIFT is responsible for stocking and packaging FMI supplies, producing inventory and accuracy benefits, and delivering them to the business unit, where delivery and replenishment is then performed by local district or branch personnel. In a minority of cases we deploy a 'drop-and-scatter' model, wherein delivery and replenishment is also performed by LIFT personnel. In 2025, approximately 11% of our FMI sales were supported through a LIFT, but over time we believe this figure can approximate 40% of our FMI sales.

**Transportation**

The ability to move product, globally and domestically, from our sources of supply to our customers is critical to the competitiveness of our business model. We utilize multiple modes of transportation to support our business model.

We transport product from our global manufacturing and supplier partners to our distribution centers. Related costs range from port fees, duties, costs related to container and shipper services, and inland trucking and intermodal charges. We consider these expenses to be a part of our landed product cost, and significant fluctuations are typically addressed through product pricing.

We transport product between our distribution centers and from our distribution centers to our selling locations. We typically transport approximately 90% of our products on our own fleet of Class 6, 7, and 8 trucks, with the remainder being on third party shippers. Costs range from lease charges, driver pay, fuel costs to support our captive fleet, and fees paid to third-party shippers. These expenses are included in cost of goods sold but are not considered a part of our landed product cost, with fluctuations typically addressed by applying freight charges to customer purchases and by securing commercial back-hauls. We primarily lease our trucks, and at December 31, 2025, we operated approximately 590 units.

We transport product from our selling locations to our customers on a fleet of pick-up, box, and other trucks. Expenses to maintain this fleet are considered selling-related transportation costs, which include lease charges, depreciation, and fuel, and are typically reflected in all other selling, general, and administrative (SG&A) expenses. We have a mix of leased and owned vehicles, and at December 31, 2025, we operated approximately 9,200 units.

**Information Systems**

Our Information Systems teams develop, implement, secure, and maintain the computer-based technology used to support business functions within Fastenal. Corporate, digital, distribution center, and vending systems are primarily supported from central locations, while each selling location uses a locally installed Point-Of-Sale system. The systems consist of custom in-house developed, purchased, and subscription licensed software. A dedicated Wide Area Network is used to provide connectivity between systems and authorized users.

**Trademarks and Service Marks**

We conduct business under various trademarks and service marks, and we utilize a variety of designs and taglines in connection with each of these marks, including ***Where Industry Meets Innovation***<sup>™</sup>*.* Although we do not believe our operations are substantially dependent upon any of our trademarks or service marks, we consider the 'Fastenal' name and our other trademarks and service marks to be valuable to our business. We have registered, or applied for the registration of, various trademarks and service marks. Our registered trademarks and service marks are presumed valid in the U.S. as long as they are in use, their registrations are properly maintained, and they have not been found to have become generic. Registrations of trademarks and service marks can also generally be renewed indefinitely as long as the trademarks and service marks are in use.

**Products**

Fastenal was founded as a distributor of fasteners and related industrial and construction supplies. This includes threaded fasteners, bolts, nuts, screws, studs, and related washers, as well as miscellaneous supplies and hardware, such as pins, machinery keys, concrete anchors, metal framing systems, wire rope, strut, rivets, and related accessories. Our fastener product line, which is primarily sold under the Fastenal product name, represented 30.5% of our consolidated sales in 2025.

Fastener distribution is complex. In most cases, the product has low per unit value but high per unit weight. This presents challenges in moving product from suppliers, most of whom are outside of North America, to our distribution centers, as well as from our distribution centers to our customer locations. At the same time, fasteners are ubiquitous in manufactured products, construction projects, and maintenance and repair while also exhibiting great geometric variability based on use and application. In many cases, a fastener is a critical part in machine uptime and/or effective use. These features have greatly influenced our logistical development, training and educational programs, support capabilities, and inventory decisions, which we believe would be difficult for competitors to replicate.

In 1993, we began to aggressively add additional product lines, and these represented 69.5% of our consolidated sales in 2025. These products, which we refer to as non-fastener product lines, tend to move through the same distribution channel, get used by the same customers, and utilize the same logistical capabilities as the original fastener product line. This logic is as true today as it was when we first began to diversify our product offering. However, over time, the supply chain for these product lines has evolved in ways independent of the fastener line. For instance, non-fastener product lines benefit disproportionately from our development of industrial vending.

------

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

The largest category of non-fastener products is our safety supplies product line, which accounted for 22.2% of our consolidated sales in 2025. This product line has seen significant sales growth in the last 10 years, which we believe is directly attributable to our success cross-selling safety supplies to customers that utilize us for non-safety products, as well as our ability to market, deploy, and service industrial vending over that period. We expect these variables to remain the primary drivers of performance for our safety supplies product line.

We plan to continue to add other product lines in the future.

In the last several decades, we have added 'private label' brands (often referred to as 'Exclusive Brands', or brands sold exclusively through Fastenal) to our non-fastener offering. Prior to 2023, each of our product categories tended to have its own private label. In 2023, we consolidated these into two labels: Body Guard<sup>®</sup>, which is our long-standing brand for North American safety supplies, and ORMADUS<sup>®</sup>, which is our global brand encompassing the remainder of our product offerings. These private label brands represented approximately 11% of our consolidated sales in 2025. We believe it is also appropriate to think about our private label sales as a percentage of our non-fastener sales for two reasons: (1) there is not a well-defined branded versus private label dynamic in fasteners as there is in non-fasteners; and (2) non-fastener data is more comparable to information reported by our peers, who do not generally have our significant mix of fastener business. Private label brand sales represented approximately 16% of our total non-fastener sales in 2025. Over time we expect our private label sales as a percentage of our total non-fastener sales to increase, although oftentimes, these increases through specific channels are masked by the relative sales growth we experience with Onsite locations, which typically have a lower percentage of total sales of private label than in branches or sales through vending devices.

Detailed information about our sales by product line is provided in Note 2 of the Notes to Consolidated Financial Statements included later in this Form 10-K. Each product line may contain multiple product categories.

**Inventory Control**

Our inventory stocking levels are determined using our computer systems, by our sales personnel at selling locations, and by our district and regional leadership. The data used for this determination is derived from sales activity from all of our selling locations, from individual selling locations, and from different geographic areas. It is also derived from supplier information and from customer demographic information. Our computer system monitors the inventory level for all stock items and triggers replenishment, or prompts a buyer to purchase, as necessary, based on an established minimum-maximum stocking level. In the past we have utilized a base inventory model for all of our branches, and such a model still exists in a smaller subset of our selling locations. Increasingly, however, branches primarily stock inventory that is deemed to be appropriate by the district and branch personnel to service the customers within their selling territory. Similarly, non-branch selling locations (primarily Onsites) stock inventory exclusively based on customer-specific arrangements. Inventories in distribution centers are established from computerized data for the selling locations served by the respective distribution center. Inventory quantities are continuously re-balanced utilizing an automated transfer mechanism we call 'inventory re-distribution'.

Inventory held at our selling locations, close to customers and available on a same-day basis, accounted for approximately 54% of our total inventory at the end of 2025. Inventory held at our distribution centers and manufacturing locations accounted for approximately 46% of our total inventory at the end of 2025. In 2025, we focused on stocking more products in our distribution centers resulting in better product availability, improved profitability, and overall efficiency gains. The distribution center and manufacturing location inventory, when combined with our trucking network, allows for fast, next-day service at a very competitive cost.

**Manufacturing and Support Services Operations**

In 2025, approximately 96% of our consolidated net sales were attributable to products manufactured by other companies to industry standards or to customer specific requirements. The remaining 4% related to products manufactured, modified, or repaired by our manufacturing businesses or our industrial services. These manufactured products consist primarily of non-standard sizes of threaded fasteners and hardware made to customers' specifications at one of our nine manufacturing locations, or standard sizes manufactured under our Holo-Krome<sup>®</sup>, Cardinal Fasteners<sup>®</sup>, and Spensall<sup>®</sup> product lines. These manufactured products represent approximately 8% of our fastener sales. The services provided by the industrial services group include, but are not limited to, tool and hoist repair, chain sling and hose fabrication, band saw blade welding, packaging, and other light manufacturing and fabrication. We may add additional services in the future. We engage in these activities primarily as a service to our customers and expect the services to continue to contribute in the range of 4% to 6% of our consolidated net sales in the future.

**Sources of Supply**

We use a diverse group of suppliers for the standard stock items we distribute. Most items distributed by our network can be purchased from several sources, although preferred sourcing is used for some stock items to facilitate quality control, strong relationships, reliable lead times, and effective costing. During 2025, we had a single supplier that accounted for more than 5% of our inventory purchases, whereas all remaining suppliers fell below that threshold.

------

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

In the case of fasteners and our private label non-fastener products, we have a large number of suppliers but these suppliers are heavily concentrated in a single geographic area, Asia. Within Asia, suppliers in China and Taiwan represent a significant source of product. Further, in many cases where we source directly from a North American supplier, the original country of origin of the acquired parts is the supplier's Asian facilities. As a result, the cost and effectiveness of our supply chain is dependent on relatively unfettered trade across geographic regions.

Beyond inventory, we have some concentration of purchasing activity. For example, we utilize a limited number of suppliers for our distribution equipment and our vehicle fleet, and primarily one supplier for our industrial vending equipment. However, we believe there are viable alternatives to each of these, if necessary.

**Customers and Marketing**

Our model is built around a broad product offering, timely fulfillment processes, convenient physical locations, extensive digital and services capabilities, and the superior service orientation and expertise of our employees. We believe we are successful because of our ability to integrate these features into supply chain solutions that are tailored to the specific challenges of our customers' operations. When deployed effectively, we have demonstrated the ability to assume responsibility for portions of our customers' sourcing operations while reducing the cost, lowering the risk, and increasing the scalability of our customers' supply chains. Our value proposition is focused on improving the operating effectiveness and reducing the total cost of ownership of our customers' supply chains.

Approximately 71% to 76% of our customers are in manufacturing end markets, which encompass heavy machinery, fabricated products, process industries (oil & gas, petrochemical, mining, pulp and paper, etc.), and transportation components (automotive, aerospace, etc.). We provide both the direct and indirect material needs of these customers. The remaining 24% to 29% of our customers fall primarily into non-residential construction (general and commercial contractors), reseller (retail and wholesale trades, dealers, and rental businesses), transportation services (air, train, maritime or truck transport, as well as warehousing and fulfillment centers), and state and local government entities, including schools, school districts, and universities.

Based on our customer profile being oriented toward manufacturing, our business has historically been cyclical. However, we believe our model has certain features that moderate the volatility of our results around cyclical changes. First, we have a large number of customers that serve a wide range of segments within the broader manufacturing market. While slumps in one industry served by us can rapidly spread to other interrelated industries, locally or globally, we still believe this customer and market segment diversity provides some insulation from economic changes that are not across multiple industries and geographic regions. Second, while a meaningful part of our sales is derived from products that are incorporated into final products, the greater proportion of our sales is derived from products used to maintain facilities. This latter source of sales tends to be impacted by cyclical forces, but its rate of change tends to be less dramatic.

Approximately 74% of our consolidated sales in 2025 were with customers whose spend was subject to a contractual agreement between ourselves and the customer. The terms and conditions of these contracts will vary from customer to customer, with the most common features being the scope of products and services rendered, product and service pricing, payment terms, delivery expectations, quality obligations, warranty and liability exposure, and contract duration. Many contracts will also incorporate expectations for direct (e.g., cost) or indirect (e.g., process productivity and efficiency) savings that are expected to be achieved over the course of the contract and the interval at which progress toward these expectations will be reviewed.

Our contractual programs fall into three broad categories:

• National accounts represent the largest proportion of our contract business, accounting for 65% of our consolidated sales in 2025. This program is aimed at multi-location customers where the scale and scope of the direct and indirect materials that need to be managed are very complex and costly. We believe our broad product offering coupled with our local presence as part of a national and increasingly international footprint, our ability to provide a consistent level of high-touch service, and our ancillary capabilities around manufacturing, quality control, and product knowledge, are attractive to these multi-site customers. Further, we believe our advantage with these customers has only been strengthened as we have added other capabilities, such as Onsite, FMI, digital solutions, and resources to serve these customers' unique demands.

• Local and regional contracts tend to establish terms and conditions for a customer's locations that have a more limited geographic scope, typically falling within an individual district or region. The scale and scope of the products and services that are addressed tend to be narrower and less complex than is the case for national account agreements. Some agreements cover the entirety of a customer's operations where the selling locations are focused in a specific geographic territory. Other agreements may represent a subset of a customer's North American or global operations, with additional selling locations either covered by separate local and regional contracts, being serviced on a transactional basis, or not being serviced at all. In the former case, we often try to migrate the customer to a national agreement.

------

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

• Government contracts establish Fastenal as an approved supplier of indirect materials to facilities managed by local, state, or municipal authorities. We do not generate meaningful direct sales from federal government agencies. These agreements are not different in function from local and regional non-government contracts. However, they generally involve different priorities, are heavily influenced by stricter regulatory obligations, and require specialized knowledge and processes to negotiate and maintain compliance.

We anticipate sales to contract customers will increase as a percentage of our total sales over time.

During 2025, no single customer represented 5% or more of our consolidated net sales.

Direct marketing continues to be the backbone of our business through our local selling personnel, as well as our non-branch selling personnel. We support our sales team with multi-channel marketing including direct mail and digital marketing, print and radio advertising, targeted campaigns, promotional flyers, and events. We have two national sports partnerships that provide significant marketing opportunities: Fastenal is the preferred indirect material supplier for the National Hockey League (NHL<sup>®</sup>), and a primary partner of Roush Fenway Keselowski Racing<sup>®</sup>, which stands as one of the longest tenured-brands in NASCAR<sup>®</sup>.

**Seasonality**

Seasonality has some impact on our sales. The first and fourth quarters of each year are typically our lower volume periods, given their overlap with winter months in North America during which our direct and indirect material sales to customers in the non-residential construction market typically slow due to inclement weather. The fourth quarter also tends to be more greatly affected by the Thanksgiving (October in Canada and November in the U.S.), Christmas, and New Year holiday periods, due to plant shut downs. In contrast, the second and third quarters of each year typically have higher sales due to stronger non-residential construction activity and relatively fewer holidays (although Good Friday will sometimes fall in the second quarter and the 4th of July will always fall in the third quarter).

**Competition**

Our business is highly competitive and includes large national distributors whose strongest presence tends to be in more densely populated areas, and smaller regional or local distributors, which compete in many of the smaller markets in which we have branches. We believe the principal competitive factors affecting the markets for our products, in no particular order, are customer service, price, convenience, product availability, and cost saving solutions.

Market strategies in industrial distribution are varied. With respect to products, many of the larger distributors have trended toward a broad-line offering over time; however, they are often still closely associated with a specific product that can influence their ability to capture market share. This association with a specific product line is often even more pronounced among smaller competitors, though many smaller competitors do deploy a broad-line model. Means of serving the customer are even more diverse. For instance, many competitors maintain a local, branch-based presence in their markets, while others use vans to sell products in markets away from their main warehouses, while still others rely on catalogs or telemarketing sales. Recent years have seen the emergence of eBusiness solutions, such as websites, and while this channel has been embraced by many traditional distributors, it also has introduced non-traditional web-based competitors into the marketplace. The diversity of product and service models supported in the marketplace is a reflection of the equally diverse product and service needs of the customer base. The large majority of our customers utilize multiple channels, from a single distributor or a range of distributors, to procure the products they need in their operations.

We believe that better service, and a competitive selling advantage, can be provided by maintaining a physical selling and stocking presence closer to the customers' location(s). As a result, we maintain selling locations in small, medium, and large markets, each offering a wide variety of products. The convenience of a large number of selling locations in a given area, combined with our ability to provide them with frequent deliveries to such branches from centrally located distribution centers, facilitates the prompt and efficient distribution of products. We also believe our FMI solutions, supported by our selling locations, provide a unique way to serve our customers with convenient access to products and cost saving solutions using a business model not easily replicated by our competitors. Having trained personnel at each location also enhances our ability to compete (see 'Employees' below).

Our Onsite service model provides us with a strategic advantage with our larger customers. Building on our core business strategy of the local branch, the Onsite model provides value to our customers through customized service while giving us a competitive advantage through stronger relationships with those customers, all with a relatively low incremental investment given the existing branch and distribution structure.

**Human Capital Resources**

**Employees**

At the end of 2025, we employed 24,489 full- and part-time employees. Of these, approximately 70% held a selling role. We characterize these personnel as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **2025** | **% of Total** | 2024 <sup>(1)</sup>  | % of Total |
| Selling personnel <sup>(2)</sup> | **17166** | **70.1%** | 16669 | 70.3% |
| Distribution/Transportation personnel | **4057** | **16.6%** | 3953 | 16.7% |
| Manufacturing personnel | **1046** | **4.3%** | 1010 | 4.3% |
| Organizational support personnel <sup>(3)</sup>  | **2220** | **9.0%** | 2070 | 8.7% |
| &nbsp;&nbsp;&nbsp;&nbsp; Total personnel | **24489** | **100.0%** | 23702 | 100.0% |

---

<sup>(1)</sup>  In the fourth quarter of 2024, we realigned certain employees as a result of a routine review of our organizational structure. While there was no change to total absolute or total FTE headcount, it produced minor shifts between headcount categories. Historical numbers have been adjusted to reflect this realignment.

<sup>(2)</sup>  Of our Selling personnel, 80%-85% are attached to a specific selling location.

<sup>(3)</sup>  Organizational support personnel consists of: (1) Sales Support personnel (37% to 42% of category), which includes sourcing, purchasing, supply chain, product development, etc.; (2) Information Technology (IT) personnel (34% to 39% of category); and (3) Administrative Support personnel (22% to 27% of category), which includes human resources (HR), Fastenal School of Business (FSB), accounting and finance, senior management, etc.

**Employee Profile**

Of the employees noted above, 19,206 are located in the U.S., 3,441 are located in Canada and Mexico, and 1,842 are located overseas in 23 other countries throughout the world.

Based on our EEO-1 data for 2025, in the U.S., females and minorities constitute 23.9% and 25.2% of our workforce, respectively. We believe these absolute figures gain further context when viewed against two additional data sets. First, over the past ten years there is a clear trend toward greater diversity in our business. Since 2015, our female and minority workforces have grown 3.4x and 9.2x faster, respectively, than our overall U.S. workforce. This trend reflects multiple dynamics in our business evolution, including the natural progression of our geographic expansion, the cycle of our promote-from-within philosophy, and efforts to improve hiring processes over time. Second, based on the U.S. Bureau of Labor Statistics data, we believe Fastenal's mix of female and minority employees is generally consistent with the proportion of females and minorities working in manufacturing and construction, which is representative of the pool of employees from which we might draw candidates. For instance, relative to the 23.9% of our U.S. workforce that is female, the proportion of females in the U.S. manufacturing and construction workforces are 29.3% and 11.2%, respectively. Similarly, relative to the 25.2% of our U.S. workforce that are minorities, the proportion of non-white (a definition utilized by the U.S. Census Bureau) individuals in the U.S. manufacturing and construction workforces are 22.2% and 12.7%, respectively.

**Health and Safety**

Employee health and safety continues to be a priority in every aspect of our business. Our culture and values continue to instill safe operations for our team. We have taken a multi-faceted approach to safety that helps us proactively manage hazards and potential safety improvement opportunities. Today, our health and safety programs span all operations including manufacturing, distribution centers, fleet and auto, and our selling network. These key business units play a dynamic role in defining how we engage with our employees on health and safety. Training, audits, inspections, risk assessments, safety coaching, and employee engagement are all programs that help us consistently manage our facility safety and employee safety. In 2025, there were over 288,000 completed health and safety engagements, which is an increase of 17% compared to 2024. Our internal scorecard system and safety management system ensure we maintain focus on a variety of risks while we sustain an inclusive safety environment that contributes to innovation and improved performance. We continue to expand and evolve our safety programs to better meet both our employee needs, and our customer needs as we strengthen our partnerships.

This commitment to, and continuous improvement toward, a safer work environment for our employees has generated excellent results. A widely accepted measure of organizational health and safety is the Experience Modification Rate (EMR). An organization's EMR is established through the comparison of a company's past and expected losses incurred through workplace injury against industry averages, which are compiled by the National Council on Compensation Insurance and consider unique variables such as the size and characteristics of an organization. Industry averages are benchmarked at a 1.00 EMR, with a reduction in the rate being reflective of an organization's ability to implement superior safety procedures and protocols,

------

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

resulting in a safer environment and reducing both personnel and financial risk. In 2025, Fastenal had an EMR of 0.45, which is 55% better than the average performance rate for our industry.

In 2025, we achieved third-party re-certification for the ISO 45001 Occupational Health and Safety Management System. This certification illustrates the strength of our health and safety programs, as well as our commitment to continual improvement to better support our growing workforce. We also sustained our status as a Review and Verification Service (RAVS) Plus Participant. This distinction is held by less than 3% of ISNetworld's 85,000+ active contractors. The goal of this program is to create a collaborative environment between hiring clients and contractor customers that encourages continual improvement in health, safety, and environmental best practices. As our business model continues to grow through our selling locations, our customer critical programs have evolved to mitigate risk and incidents, while meeting customer specific needs. This partnership with our customers allows us to collaborate and expand our health and safety programs to enhance our customers' workplace safety performance.

**Employment and Compensation Philosophy**

Fastenal's success is defined by our people. Our cultural values – *Ambition*, *Integrity*, *Innovation,* and *Teamwork* – are woven into the fabric of our HR processes and protocols, and inform our employment and compensation philosophies.

Several principles underpin our employment philosophy. One principle is decentralization: placing employees close to our customers' operations and trusting these employees to independently make local decisions to provide differentiated local service. A second principle is that we are a passionately promote-from-within company, guided by a belief that if you work hard, make great decisions, learn from mistakes, and exemplify our cultural values, you should receive greater opportunity and responsibility. We believe these principles cultivate an entrepreneurial mindset and foster an environment of trust and empowerment.

As it relates to our compensation philosophy, we believe our combination and mix of base and bonus pay motivates our people to high levels of individual and company success, as the goals and objectives have been repeatedly demonstrated to be achievable with superior effort. We are guided by simple principles. First, compensation programs should be easy to understand, with goals and objectives that are clearly communicated and resources for success that are provided. They should be calculable by the employee and numbers-driven (e.g., not subjective). Second, total compensation should have a significant component that is based on how well the employee has grown their piece of the business and served our customers. Third, employees should receive incentives as soon as practical upon attainment of the goal.

Approximately 70% of our employees interface directly with customers on a daily or frequent basis, with the remainder supporting the selling efforts of our customer-facing employees. Typical pay arrangements provide a base amount paid periodically during the month, along with a major opportunity to earn bonus amounts, paid monthly, based on growth in sales, gross or pre-tax profit achieved, and prudent management of working capital. In certain roles, there may also be a portion of compensation based on contribution to attaining predetermined departmental or project and cost containment goals, most of which are focused on either customer service or better execution of company-wide activities.

Because we believe the growth in our stock value should be the reward for achieving long-term success consistent with being an owner, we have a stock option plan. In the case of certain foreign employees, we have a stock appreciation rights plan. All of our employees are eligible to receive stock option grants or stock appreciation rights.

We believe our combination of short- and long-term rewards and incentives has proven successful as reflected in our historic performance and levels of employee retention and turnover.

Our employees are not subject to any collective bargaining agreements, and we have experienced no work stoppages. We believe our employee relations are good.

**Talent Acquisition and Development**

Fastenal's values are integral to our employment process and serve as guideposts for leadership. The ultimate goal is straightforward: find great people, ask them to join, and give them a reason to stay. Reasons to stay include training, opportunity, and a welcoming environment. From a practical standpoint, this means that we attract a broad group of candidates and then hire the candidate who is the best match for the position based on their skills and abilities. In accordance with our decentralized leadership structure, we believe the person best suited to make this decision is the local leader trying to fill the opening. In light of our promote-from-within philosophy, we know we are hiring a potential future leader with every new hire.

Our HR department develops efficient processes to expand our reach and pool of diverse talent while balancing the needs and requirements of data collection and storage. We have created a standardized framework for posting jobs and interviewing for positions, supplemented with training through the FSB (our internal corporate university program — Fastenal School of Business). We have an HR Compliance team that is heavily involved in developing this standardized framework, which ensures its integrity. Not only is this process followed for all new hires, we replicate the same procedures for any internal transfers and promotions.

------

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

The FSB develops and delivers a comprehensive array of industry and company-specific training and development programs that are offered to our employees. The programs are offered through a combination of classroom instructor-led training, virtual instructor-led training, and online learning. FSB provides core curricula focused on key competencies determined to be critical to the success of our employees' performance. In addition, we provide specialized educational tracks within various institutes of learning, as well as training plans based on roles within Fastenal. These institutes of learning are advanced levels that provide specific concentrations of education and development and have been designed to focus on critical aspects of our business, such as leadership, effective best practices, sales and marketing, products, supply chain, and distribution.

**Product Sourcing Endeavors**

Sourcing from suppliers with good standing is the foundation of an ethical supply chain. We expect our suppliers to comply with all relevant regulations and applicable standards. Our teams conduct risk analysis for suppliers who want to do business with us and require them to provide additional supporting documentation affirming their ethics, quality, and reliability. This ensures they meet our standards in these areas and are complying with Fastenal's Global Supplier Purchase Order Terms & Conditions and Supplier Code of Conduct. Utilizing third-party tools and global databases, Fastenal actively monitors government sanctions, denied party listings, withhold release orders, export restriction updates, financial status, adverse media, and multiple other official exclusion lists that provide information on any known risk of any entities and selling locations with which Fastenal engages, and screens all business partners against those lists. Additionally, we monitor key areas of trade-related risk, including dual-use goods, trade cases, anti-dumping and counter-vailing cases, and other protectionist trade measures for all countries that products are traded in. As part of our comprehensive Supply Chain Security program, we also evaluate our suppliers' approach to labor to ensure that they are using appropriate, and appropriately compensated, employees and ensure upstream supply chain visibility on globally sourced products.

With a local and global supplier base, continuous evaluation and local representation is a necessity to ensure protocols are flagged when risk may be evident, ensuring a safeguard against poor and/or impaired quality and regulatory violations that may otherwise impact our reputation or ability to effectively operate in the marketplace. This is performed not only at the time of supplier vetting and onboarding, but for the life of the relationship with the supplier. This process promotes a supply chain that is supportive of Fastenal's Global Supplier Purchase Order Terms & Conditions and Supplier Code of Conduct. In the event of non-compliance or potential risk, we work with the supplier to correct the situation. If remediation efforts are not undertaken to ensure the supplier remains in compliance with Fastenal's standards and code of conduct, alternative sources of supply may be considered to ensure the integrity of our supply chain. Supply chain compliance representatives are placed in international corporate offices to ensure global coverage and governance, ensuring that no matter where a customers' operations may take them, Fastenal has the infrastructure, resources, and internal processes established to perform its supply chain governance obligations.

In 2025, approximately 24% of our total company-wide inventory spend was with small and/or certified/impactful businesses. Our Supplier Certification program supports customers who require reporting to document their supply chain relationships with various business types.

**ITEM 1A. RISK FACTORS**

In addition to the other information in this Form 10-K, the following factors should be considered in evaluating our business. Our operating results depend upon many factors and are subject to various risks and uncertainties. The material risks and uncertainties known to us which may cause our operating results to vary from anticipated results or which may negatively affect our operating results and profitability are as follows:

**Company-Specific Risks**

***Operational Risks***

***Products that we sell may expose us to potential material liability for property damage, environmental damage, personal injury, or death linked to the use of those products by our customers.*** Some of our customers operate in challenging industries in which there is a material risk of catastrophic events. We are actively seeking to expand our sales to certain categories of customers, some of whose businesses may entail heightened levels of such risk. If any of these events are linked to the use of any of our products by our customers, claims could be brought against us by those customers, by governmental authorities, and by third parties who are injured or damaged as a result of such events. In addition, our reputation could be adversely affected by negative publicity surrounding such events regardless of whether or not claims against us are successful. While we maintain insurance coverage to mitigate a portion of this risk and may have recourse against our suppliers for losses arising out of defects in products procured from them, we could experience significant losses as a result of claims made against us to the extent adequate insurance is not in place, the products are manufactured by us or legal recourse against our suppliers is otherwise not available, or our insurers or suppliers are unwilling or unable to satisfy their obligations to us.

***Interruptions in the proper functioning of information systems or the inability to maintain or upgrade our information systems, or convert to alternate systems in a timely and efficient manner, could disrupt operations, cause unanticipated increases in costs and/or decreases in sales, and result in less efficient operations.*** The proper functioning of our information systems is critical to many aspects of our business and we could be adversely affected if we experience a disruption or data loss relating to our information systems and are unable to recover in a timely manner. Our information systems are protected with robust backup systems and processes, including physical and software safeguards and remote processing capabilities. Still, information systems are vulnerable to natural disasters, power losses, unauthorized access, cybersecurity incidents, telecommunication failures, and other problems. In addition, certain software used by us is licensed from, and certain services related to our information systems are provided by, third parties who could choose to discontinue their products or services or their relationship with us. It is also possible that we are unable to improve, upgrade, maintain, and expand our information systems. Our ability to process orders, maintain proper levels of inventories, collect accounts receivable, pay expenses, and maintain the security of Fastenal and customer data, as well as the success of our growth drivers, is dependent in varying degrees on the effective and timely operation and support of our IT systems. If critical information systems fail or these systems or related software or services are otherwise unavailable, if we experience extended delays or unexpected expenses in securing, developing, and otherwise implementing technology solutions to support our growth and operations, or if certain insurance coverages are limited in their capabilities or affordability, it could adversely affect our profitability and/or ability to grow.

***We may not be successful in adopting and integrating emerging technologies.*** Our ability to maintain and enhance our competitive position depends in part on our capacity to adopt and integrate emerging technologies, including AI and advanced analytics, into our operations, customer solutions, and supply chain management. If we fail to identify, develop, or implement relevant technologies in a timely and cost-effective manner, or if such technologies do not deliver the anticipated benefits, our business operations, customer experience, and financial performance could be adversely affected. Additionally, our competitors may leverage these technologies more effectively, which could result in a loss of market share. The evolving regulatory landscape surrounding AI and data usage may also introduce compliance risks and additional costs. These factors could materially and adversely impact our business, financial condition, and results of operations.

***The ability to adequately protect our intellectual property or successfully defend against infringement claims by others may have an adverse impact on operations.*** Additionally, our business relies on the use, validity, and continued protection of certain proprietary information and intellectual property, which include current and future patents, trade secrets, trademarks, service marks, copyrights, and confidentiality agreements, as well as license and sublicense agreements to use intellectual property owned by affiliated entities or third parties. Unauthorized use of our intellectual property by others could result in harm to various aspects of the business and may result in costly and protracted litigation in order to protect our rights. In addition, we may be subject to claims that we have infringed on the intellectual property rights of others, which could subject us to liability, require us to obtain licenses to use those rights at significant cost, or otherwise cause us to modify our operations.

***Our ability to successfully attract, develop, and retain qualified personnel to staff our selling locations could impact labor costs, sales at existing selling locations, and the successful execution of our growth drivers.*** Our success depends in part on our ability to attract, motivate, and retain a sufficient number of qualified employees, including inside and outside branch associates, Onsite managers, contract account sales representatives, and logistical and administrative support personnel, who understand and appreciate our culture and are able to adequately represent this culture to our customers. Qualified individuals of the requisite caliber and number needed to fill these positions may be in short supply in some areas, and the turnover rate in the industry is high, particularly for less tenured employees. If we are unable to hire and retain personnel capable of consistently providing a high level of customer service, as demonstrated by their enthusiasm for our culture and product knowledge, our sales could be materially and adversely affected. Additionally, competition for qualified employees could require us to pay higher wages to attract a sufficient number of employees. An inability to recruit and retain a sufficient number of qualified individuals in the future may also delay the planned expansion of our various selling channels.

***Cybersecurity incidents, or violations of data privacy laws and regulations, could cause us to experience certain operational interruptions, incur substantial additional costs, become subject to legal or regulatory proceedings, or suffer damage to our reputation in the marketplace.*** The nature of our business requires us to receive, retain, and transmit certain personally identifying information that our customers provide to purchase products or services, register on our websites, or otherwise communicate and interact with us. While we have taken and continue to undertake significant steps to protect our customer and confidential information, a compromise of our data security systems or those of businesses with which we interact could result in information related to our customers or business being obtained by unauthorized persons. We develop and update processes and maintain systems in an effort to try to prevent such unauthorized access, and have established and maintained disclosure controls and procedures that would permit us to make accurate and timely disclosures of any material event, including any cybersecurity event. The development and maintenance of these processes and systems are costly and require ongoing monitoring and updating as technologies change and efforts to overcome security measures become more sophisticated. Consequently, despite our efforts, the possibility of cybersecurity incidents cannot be eliminated entirely. There can be no assurance that we will not experience a cybersecurity incident that may materially impact our business. While we also seek to obtain assurances that third parties we interact with will protect confidential information, there is a risk the confidentiality of data held or accessed by third parties may be compromised. If a compromise of our data security were to occur, it could interrupt our operations, subject us to additional legal, regulatory, and operating costs, and damage our reputation in the marketplace. In addition, regulatory authorities have increased their focus on how companies collect, process, use, store, share, and transmit personal data. Privacy security laws and regulations, including the European Union General Data Protection Regulation 2016, the California Consumer Protection Act, and other similar privacy laws, pose increasingly complex compliance challenges, which may increase compliance costs, and any failure to comply with data privacy laws and regulations could result in significant penalties.

***Changes in customer or product mix, downward pressure on sales prices, an inability to capture price increases in response to increased costs associated with tariffs, and changes in volume or timing of orders have caused and could continue to cause our gross profit percentage to fluctuate or decline in the future.*** Changes in our customer and product mix have caused our gross profit percentage to decline and could cause our gross profit percentage to further fluctuate or decline. For example, we have experienced a sustained increase in the proportion of our sales attributable to both non-fastener products and contract accounts and Onsite customers. Non-fastener products typically have a lower gross profit percentage than fasteners because in many cases non-fastener products are less technical, have shorter supply chains, and are easier to transport. Similarly, contract accounts and Onsite customers typically have a lower gross profit percentage than smaller customers by virtue of their scale, available business, and broader offering of products which typically have lower gross profit percentages. Whether and to what extent this adverse mix impact will result in a decline of our gross profit percentage in any given year or period will depend on the extent to which they are offset by positive impacts to gross profit percentage during such year or period. Setting aside the circumstances of any given year or period, however, customer and product mix have contributed to the decline of our gross profit percentage over time and, based on the anticipated sources of our future growth, will likely continue to reduce our gross profit percentage into the foreseeable future. In 2025, tariff rates increased on many of the parts we sell. Additionally, new tariffs were enacted. There are other variables that could cause our gross profit percentage to decline, including downward pressure on sales prices due to deflation, increases in overseas freight charges, the inability of freight sales to leverage the expenses associated with our captive trucking fleet, pressure from customers to reduce costs, or increased competition. We could experience reductions in the volume of purchases we make from our suppliers, which could reduce supplier volume allowances. We may not be able to pass higher product costs along to customers if those customers have ready product or supplier alternatives in the marketplace. In 2025, the softer manufacturing economy continued to cause relative weakness in our more cyclical and higher gross margin fastener product line versus our non-fastener product lines. Similarly, we continued to execute initiatives aimed at accelerating key account penetration, which resulted in relative growth in our lower gross margin contract accounts. The combination of these two events produced pressure on our product gross profit percentage in 2025 from product and customer mix.

***Our SG&A expenses could grow more rapidly than net sales, which could result in failure to achieve our goals related to leveraging sales growth into higher net income.*** Over time, we have generally experienced an increase in our SG&A expenses, including costs related to payroll, occupancy, freight, and IT, among others, as our net sales have grown. However, historically, a portion of these expenses has not increased at the same rates as net sales, allowing us to leverage our growth and sustain or expand our operating profit margins. There are various scenarios where we may not be able to continue to achieve this leverage as we have been able to do in the past. For instance, it is typical that when demand slows or declines, most commonly from cyclical or general market factors (although it could be due to customer losses or some other company-specific event), our SG&A expenses do not fall as quickly as net sales. It is also possible that in the future we will elect to make investments in SG&A expenses that would result in costs growing faster than net sales. In addition, market variables, which include but are not exclusive of labor rates, energy costs, legal costs, and health care costs, could move in such a way as to cause us to not be able to manage our SG&A expenses so as to leverage our sales growth into higher net income. In 2025, our incentive compensation programs did not leverage during the year due to increased sales and pretax profit growth compared to contraction or very low growth in most periods of 2024.

***Our inability to attract or transition key executive officers may divert the attention of other members of our senior leadership and adversely impact our existing operations.*** Our success depends on the efforts and abilities of our key executive officers and senior leadership. In the event of voluntary or involuntary vacancies in our executive team in the future, the extent to which there is disruption in the oversight and/or leadership of our business will depend on our ability to either transition internal, talented individuals or recruit suitable replacements to serve in these roles. In addition, difficulties in smoothly implementing any transition to new members of our executive team, or recruiting suitable replacements, could divert the attention of other members of our senior leadership team from our existing operations. As previously disclosed, on December 19, 2025, Mr. Florness informed our board of directors of his decision to voluntarily step out of his role as our chief executive officer, effective as of the CEO Transition Date, and his decision to resign from our board of directors, effective as of the CEO Transition Date. On December 19, 2025, our board of directors also appointed Mr. Watts, our current president and chief sales officer, as the next chief executive officer of Fastenal, effective as of the CEO Transition Date. If we are unable to manage this transition effectively, our operations may be disrupted.

***Our competitive advantage in FMI solutions, which includes industrial vending (FASTVend) and bin stock (FASTStock and FASTBin) tools, could be eliminated and, in the case of FASTVend and FASTBin, the loss of key suppliers of equipment and services could be impactful and result in failure to deploy devices. Certain circumstances could lead to a short-term inability to promote and/or install our FMI solutions.*** We believe we have a competitive advantage in industrial vending and bin stock due to our hardware and software, our local presence (allowing us to service devices and bins more rapidly and with less burden on our customers), our depth of products that lend themselves to being dispensed through industrial vending devices or bin stocks, and, particularly in North America, our distribution strength. These advantages have developed over time; however, other competitors could respond to our expanding industrial vending and bin stock position with highly competitive platforms of their own. Such competition could negatively impact our ability to expand our industrial vending and bin stock tools or negatively impact the economics of that business. In addition, we currently choose to rely on a limited number of suppliers for our vending devices, RFID technology, and IR technology used in our FASTVend and FASTBin platforms. While devices, software, and services can be obtained from other sources, loss of our current suppliers could be disruptive and could result in our failure to meet short- or long-term goals related to the numbers of FASTVend and FASTBin devices we are able to deploy. Certain circumstances may reduce short-term customer receptivity to adopting our FMI services. For instance, during periods of dramatic change in economic activity, some customers may prioritize managing existing operations over adopting new technologies until business circumstances change.

***We may be affected by global climate change or legal, tax, regulatory, or market responses to such change.*** The concern over climate change has led to legislative and regulatory initiatives aimed at reducing greenhouse gas emissions. Compliance with any new or more stringent laws or requirements, or stricter interpretations of existing laws, could require additional expenditures by us or our suppliers. In addition, many of the regulations that have been issued create mandatory, annual reporting requirements related to carbon emissions and other sustainability-related information that will ultimately be subject to audit. If we are unable to respond to any new regulatory or market changes in a timely fashion or at all in a way that satisfies regulators and/or our suppliers and customers, it could directly or indirectly affect our business, supply chains, financial condition, results of operations, and cash flows. Furthermore, climate change may present additional physical risks to our operations and lead to an increased frequency of unusual or extreme weather conditions, which could disrupt our supply chain or harm or disrupt our operations or those of our customers or suppliers.

***We may be unable to meet our goals regarding the growth drivers of our business.*** Our sales growth is dependent primarily on our ability to attract new customers and increase our activity with existing customers within North America and abroad. In recent years, we have increased the resources devoted to developing a multi-dimensional, differentiated service offering, including our Digital Footprint (which incorporates our FMI and eBusiness capabilities), contract accounts, international capabilities, and process and consumption analytics. While we have taken steps to build momentum in the growth drivers of our business, we cannot assure you those steps will lead to sales growth. Failure to achieve any of our goals regarding our Digital Footprint, contract accounts, international capabilities, analytics, or other growth drivers could negatively impact our long-term sales and profit growth. In addition, failure to identify appropriate targets for the growth drivers of our business or failure to persuade the appropriate targets to adopt these offerings once identified may adversely impact our internally developed and/or externally communicated deployment objectives.

***The ability to identify new products and product lines, and integrate them into our selling efforts and distribution network, may impact our ability to compete, our ability to generate additional sales, and our profit margins.*** Our success depends in part on our ability to develop product expertise at our selling locations and through our specialist roles and identify future products and product lines that complement existing products and product lines and that respond to our customers' needs. We may not be able to compete effectively unless our product selection keeps up with trends in the markets in which we compete or trends in new products. In addition, our ability to integrate new products and product lines into our selling locations and distribution network could impact sales and profit margins.

***The ability to adequately protect our reputation may have an adverse impact on operations and profitability.*** The Fastenal name is valuable to our business, as well as to the implementation of our strategies for expanding our business. Maintaining, promoting, and positioning our brand will depend largely on our ability to provide high quality products, deliver consistent services, and improve our customers' business operations. Further, information on Fastenal, including our products and services, can be more easily accessed and more quickly disseminated through traditional and social media and digital channels. Should we fail to deliver a positive customer experience or should our public image be tarnished by negative publicity, whether or not based in fact, it could jeopardize our reputation and discourage customers from purchasing our products and services, which in turn could adversely affect our ability to grow our sales and profitability.

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

***We may not be able to compete effectively against traditional or non-traditional competitors, which could cause us to lose market share or erode our gross and/or operating income profit and/or percentage.*** The industrial, construction, and maintenance supply industry, although slowly consolidating, still remains a large, fragmented, and highly competitive industry. Our current or future competitors may include companies with similar or greater market presence, name recognition, and financial, marketing, technological, and other resources, and we believe they will continue to challenge us with their product selection, financial resources, technological advancements, and services. Increased competition from brick-and-mortar retailers could cause us to lose market share, reduce our prices, or increase our spending. Similarly, the emergence of online retailers, whether as extensions of our traditional competition or in the form of major, non-traditional competitors, could result in easier and quicker price discovery and the adoption of aggressive pricing strategies and sales methods. These pressures could have the effect of eroding our gross and/or operating income profit and/or percentage over time.

***We may not be successful in integrating acquisitions and achieving intended benefits and synergies.*** Historically, substantially all of our growth has been organic. However, we have completed several acquisitions over the last decade and expect to continue to pursue strategic acquisitions that we believe will either expand or complement our business in new or existing markets or further enhance the value and offerings we are able to provide to our existing or future potential customers. Acquisitions involve numerous risks and challenges, including, among others, a risk of potential loss of key employees of an acquired business, inability to achieve identified operating and financial synergies anticipated to result from an acquisition, diversion of our capital and our management's attention from other business issues, and risks related to the integration of the acquired business, including unanticipated changes in our business, our industry, or general economic conditions that affect the assumptions underlying the acquisition. Any one or more of these factors could cause us to not realize the benefits anticipated to result from the acquisitions.

***Equity Risks***

***Our stock price will fluctuate, and at times these fluctuations may be volatile***. The prices of markets and individual equities tend to fluctuate. These fluctuations commonly reflect events, many of which may be fully or partially outside of our control, that may change investors' perception of our future income growth prospects, including changes in economic conditions, ability to execute business strategy, the impacts of public policy, investor sentiment, competitive dynamics, and many other factors. While the sources of stock price fluctuation can be common across companies, the magnitude of these fluctuations can vary for different companies. This is commonly measured by beta, which is an individual stock's volatility in relation to the overall market. Our stock price has traditionally had a high beta value, which means fluctuations in the price of our shares will often be sharper than what is experienced by broader market indices. We can provide no assurance that the above-average historical volatility of our stock versus the broader market will moderate. Volatility in our stock price could also result in the filing of securities class action litigation, which could result in substantial costs and the diversion of our management's time, attention, and resources.

***There can be no assurance that our stock price will continue to reflect the current multiple of income over time.*** Stock prices, including ours, are commonly thought to be a function of income compounded by a multiple. This is often referred to as a price-to-earnings (P/E) ratio, although other forms of multiples are often utilized by investors to value Fastenal shares. Historically, investors have given our income a higher multiple, or premium, than is typical of the broader industrial sector with which we are typically associated. We believe we have earned this premium by virtue of a long history of superior growth, profitability, and returns. However, to the extent that we fail to successfully execute our growth strategies and/or poorly navigate the risks that surround our business, including those described throughout this section, or to the extent our industry (industrial distribution, or industrial stocks in general) loses favor in the marketplace, there can be no assurance that investors will continue to afford a premium multiple to our income, which could adversely affect our stock price.

***We cannot provide any guaranty of future dividend payments or that we will continue to purchase shares of our common stock pursuant to our share purchase program.*** Although our board of directors has historically authorized the payment of quarterly cash dividends on our common stock and indicated an intention to do so in the future, there are no assurances that we will continue to pay dividends in the future or continue to increase dividends at historic rates. In addition, although our board of directors has authorized share purchase programs and we purchased shares in 2022, 2020, and prior years through these programs, we may discontinue doing so at any time. Any decision to continue to pay quarterly dividends on our common stock, to increase those dividends, or to purchase our common stock in the future will be based upon our financial condition and results of operations, the price of our common stock, credit conditions, recommendations of management, and such other factors as are deemed relevant by our board of directors.

**General Economic and Operating Risks**

***Operational Risks***

***Products manufactured in foreign countries may cease to be available, which could adversely affect our inventory levels and operating results.*** We obtain certain of our products, and our suppliers obtain certain of their products, from China, Taiwan, South Korea, and other foreign countries. Our suppliers could discontinue or experience disruption in selling products manufactured in foreign countries at any time for reasons that may or may not be in our control or our suppliers' control, including foreign government regulations, domestic government regulations, disruption in trade relationships and agreements, political unrest, war, disease, labor availability, or changes in local economic conditions. Additionally, the shipment of goods from foreign countries could be delayed by container shipping companies encountering financial, capacity, or other difficulties. Our operating results and inventory levels could suffer if we are unable to promptly replace a supplier or shipper who is unwilling or unable to satisfy our requirements with another supplier or shipper providing products and services of comparable quality and utility.

***A downturn in the economy or in the principal markets served by us and other factors may affect customer spending, which could harm our operating results.*** In general, our sales are the result of planned and unplanned customer spending on products used in production of final goods, infrastructure construction, and/or the maintenance of facilities. This spending is affected by many factors, including, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general business conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• business conditions in our principal markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the value of local currencies relative to our functional currency, the U.S. dollar;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increases (inflation) or decreases (deflation) in the cost of products from our vendors, transportation services, energy and fuel prices, and electrical power rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• liquidity in credit markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• taxation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• government regulations and actions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the impact on customer demand or availability of goods and services based on labor shortages or work stoppages;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• unemployment trends;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• terrorist attacks and acts of war;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• impact of higher sustained global temperatures (climate change);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• acts of God, which may include, but are not limited to, weather events, earthquakes, pandemics, etc.; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other matters that influence customer confidence and spending.

A downturn in either the national or local economies where we operate, or in the principal markets served by us, or changes in any of the other factors described above, could negatively impact sales at our selling locations, sales through our other selling channels, and the level of profitability of those selling locations and other selling channels. In 2025, our results continued to be impacted by soft manufacturing sector business conditions.

***Trade policies could make sourcing product from overseas more difficult and/or more costly, and could adversely impact our gross and/or operating profit percentage.*** We source a significant amount of the products we sell from outside of North America, primarily Asia. We have made significant structural investments over time to be able to source both directly from Asia through our wholly-owned, Asia-based subsidiary, FASTCO Trading Co., Ltd., and indirectly from suppliers that procure product from international sources. This was initially necessary due to the absence of significant domestic fastener production, but over time we have expanded our non-fastener sourcing as well, and at this time it may be difficult to adjust our sourcing in the short term. In light of this, changes in trade policies could affect our sourcing operations, our ability to secure sufficient product to serve our customers and/or impact the cost or price of our products, with potentially adverse impacts on our gross and operating profit percentages and financial results. China represents a significant source of product for North America. In addition, we move and source products within North America. Any trading disruption (tariffs, product restrictions, etc.) between Canada, the U.S., and Mexico, or disruption in their respective trading relationships with other nations can adversely impact our business. Since February 2025, the U.S. government has imposed additional duties and tariffs in an effort to promote U.S. production of goods and improved trade balance with our global trading partners. This environment has been very fluid, resulting in several changes to the duties and tariffs enacted throughout the year. Certain of the duties and tariffs enacted are being challenged from a legal perspective. We are closely monitoring these developments, which could have an adverse impact on our business and financial results. There can be no assurances that these disruptions will not continue or increase in the future, with the previously mentioned countries or additional countries with which we do business. The degree to which these changes in the global marketplace affect our financial results will be influenced by the specific details of the changes in trade policies, their timing and duration, and our effectiveness in deploying tools to address these issues.

***Changes in energy costs and the cost of raw materials used in our products could impact our net sales, cost of sales, gross profit percentage, distribution expenses, and occupancy expenses, which may result in lower operating income.*** Our suppliers can experience significant fluctuation over time in the cost of raw materials (e.g., steel, plastic, etc.) used to produce their products. They can also experience significant fluctuation in the cost of energy consumed in their production processes and in the cost of fuel consumed to transport their products. These suppliers typically look to pass their increased costs along to us through price increases. We also consume energy and fuel in our own operations, and can experience direct and significant fluctuation in our own costs. Increases in the cost of fuel or raw materials could be damaging to us, decreases in those costs, particularly if severe, could also adversely impact us by creating deflation in selling prices, which could cause our gross profit to decline, or by negatively impacting customers in certain industries, which could cause our sales to those customers to decline. Failure to fully pass any such increased prices and costs through to our customers or to modify our activities to mitigate the impact would have an adverse effect on our operating income.

***We are exposed to foreign currency exchange rate risk, and changes in foreign exchange rates could increase the cost of purchasing products and impact our foreign sales.*** Given that we were founded and remain based in the U.S. and that we are publicly traded in the U.S., we report our results based on the U.S. dollar. Because the functional currency related to most of our non-U.S. operations is the applicable local currency, we are exposed to foreign currency exchange rate risk arising from transactions in the normal course of business. Fluctuations in the relative strength of foreign economies and their related currencies could adversely impact our ability to procure products at competitive prices and our foreign sales. Historically, our primary exchange rate exposure has been with the Canadian dollar as our Mexican activities are primarily conducted in U.S. dollars and our non-North American operations are relatively small in scale. There can be no assurance that currency exchange rate fluctuations with the Canadian dollar and other foreign currencies will not adversely affect our results of operations, financial condition, and cash flows. While the use of currency hedging instruments may provide us with protection from adverse fluctuations in currency exchange rates, we are not currently using these instruments and we have not historically hedged this exposure. If we decide to do so in the future, we could potentially forego the benefits that might result from favorable fluctuations in currency exchange rates.

***Our current estimates of total market potential as well as the market potential of our business strategies could be incorrect.*** We believe we have a significant opportunity for growth based on our belief that North American market demand for the products we sell is estimated to exceed $140 billion. This figure is not derived from an independent organization or data source that aggregates and publishes widely agreed-upon demand and market share statistics. Instead, we have identified this figure based on our own experience in the marketplace for our products and by evaluating estimates from other sources. If we have overestimated the size of our market, and in doing so, underestimated our current share of it, the size of our opportunity for growth may not be as significant as we currently believe. Similarly, we have provided estimates of the opportunities we have with some of our specific growth strategies, such as FMI solutions and Onsite locations. Within North America, we believe the potential market opportunity for industrial vending is approximately 1.7 million devices and we have identified over 13,000 customer locations with the potential to implement our Onsite service model within our traditional manufacturing and construction customer base. We have identified additional markets, such as government, healthcare, and academia, and geographies into which we can sell our FMI solutions, which would increase the number of identified potential FMI solutions or Onsite locations. However, our presence in emerging markets and geographies is not as established as is the case in our traditional markets and geographies, which could extend the sales cycle. As is the case for total market size, we use our own experience and data to arrive at the size of these potential opportunities and not independent sources. These estimates are based on our business model today, and the introduction or expansion of other business strategies could cause them to change. In addition, the market potential of a particular business strategy may vary from expectations due to a change in the marketplace (such as changes in customer concentration or needs), a change in the nature of that business strategy, or weaker than anticipated acceptance by customers of that business strategy. We cannot guarantee that our market potential estimates are accurate or that we will ultimately decide to expand our industrial vending or Onsite service models as we anticipate to reach the full market opportunity.

***The industrial, construction, and maintenance supply industry is consolidating, which could cause it to become more competitive and could negatively impact our market share, gross profit, and operating income.*** The industrial, construction, and maintenance supply industry in North America is consolidating, reflecting two factors. First, our customers' needs are evolving to reflect a greater awareness of the total cost and risk of fulfillment and their need to have consistent sources of supply at multiple locations, including outside of North America. Second, providing these capabilities to our customers requires increasing investment in hardware, software, and analytic capabilities that require a certain degree of scale to support. While we believe that in a fragmented market such as exists for industrial supplies these emerging trends favor large distributors such as Fastenal, as the industry consolidates into fewer and larger competitors it may become more difficult to differentiate our product and service offering from that of our competitors. We also continue to see consolidation among our suppliers. This trend could result in fewer and larger suppliers, with greater channel power and negotiating leverage. There can be no assurance we will be able in the future to take effective advantage of the trend toward consolidation within our industry or among our suppliers. In either or both cases, the trend toward consolidation could make it more difficult for us to maintain our growth and/or gross and operating profit. Furthermore, as our industrial customers face increased foreign competition, and potentially lose business to foreign competitors, or shift their operations overseas in an effort to reduce expenses, we may face increased difficulty in growing and maintaining our market share.

***The occurrence of a widespread public health crisis could have a material adverse effect on our business, results of operations, and financial condition.*** A public health crisis, if sufficiently widespread as to affect economic activity, could negatively impact our business. Mitigation efforts and prescriptions may be facilitated by regulatory authorities, which could limit our flexibility to pursue alternative, potentially more favorable, means of limiting these negative impacts. The effects on our business efforts to mitigate the effects of the crisis may include a reduction in demand, inefficiencies due to workplace accommodations, reduced availability of personnel, supply chain disruption, or constraints on product availability, among other difficulties. In any such event, the severity, duration, and extent of the crisis can be difficult to predict, which can make it difficult to anticipate the magnitude and length of the impact on our sales, profits, and/or cash flow. It can also be difficult to anticipate what the effect on business conditions will be as the impacts of any public health crisis fade and mitigating policies are reversed.

***Inclement weather and other disruptions to the transportation network could adversely impact our distribution system and demand for our products.*** Our ability to provide efficient distribution of core business products to our branch network is an integral component of our overall business strategy. Disruptions at distribution centers or shipping ports may affect our ability to both maintain core products in inventory and deliver products to our customers on a timely basis, which may in turn adversely affect our results of operations. In addition, severe weather conditions could adversely affect demand for our products in particularly hard hit regions.

***Legal, Regulatory, and Compliance Risks***

***Failure to maintain an effective system of internal controls over business processes and/or financial reporting could materially impact our business and results.*** Fastenal's management is responsible for establishing and maintaining effective internal controls designed to provide reasonable assurance regarding the achievement of objectives relating to operations, reporting, and compliance. Any system of internal controls, no matter how well designed and operated, can only provide reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a system of controls must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all systems of internal controls, internal controls over business processes and financial reporting may not prevent or detect fraud or misstatements. Any failure to maintain an effective system of internal controls over business processes and financial reporting could limit our ability to report our financial results accurately and timely or to detect and prevent fraud, and could expose us to litigation, economic loss, or adversely affect the market price of our common stock.

***Our business is subject to a wide array of operating laws and regulations in every jurisdiction where we operate. Compliance with these laws and regulations increases the cost of doing business and failure to comply could result in the imposition of fines or penalties, damage to our reputation, or the termination of contracts.*** We are subject to a variety of laws and regulations including without limitation import and export requirements, anti-bribery and corruption laws, product compliance laws, environmental laws, foreign exchange controls and cash repatriation restrictions, advertising regulations, data privacy (including in the U.S., the California Consumer Privacy Act, as amended by the California Privacy Rights Act, and in the European Union, the General Data Protection Regulation 2016, with interpretations varying from state to state and country to country) and cybersecurity requirements (including protection of information and incident responses), regulations on suppliers regarding the sources of supplies or products, labor and employment laws, and anti-competition regulations. In addition, as a supplier to federal, state, and local government agencies, we must comply with certain laws and regulations relating specifically to the formation, administration, and performance of our governmental contracts. We are also subject to governmental audits and inquiries in the normal course of business. Ongoing audit activity and changes to the legal and regulatory environments could increase the cost of doing business, and such costs may increase in the future as a result of changes in these laws and regulations or in their interpretation. While we have implemented policies and procedures designed to facilitate compliance

------

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

with these laws and regulations, there can be no assurance that our employees, contractors, or agents will not violate such laws and regulations, or our policies. Any such violations could result in the imposition of fines and penalties, damage to our reputation, and, in the case of laws and regulations relating specifically to governmental contracts, the loss of those contracts.

***Tax laws and regulations require compliance efforts that can increase our cost of doing business and changes to these laws and regulations could impact financial results.*** We are subject to a variety of tax laws and regulation in the jurisdictions in which we operate. Maintaining compliance with these laws can increase our cost of doing business and failure to comply could result in audits or the imposition of fines or penalties. Further, our future effective tax rates in any of these jurisdictions could be affected, positively or negatively, by changing tax priorities, changes in statutory rates, and/or changes in tax laws or the interpretation thereof, including any changes resulting from the new presidential administration in the U.S. In 2025, the One Big Beautiful Bill Act was passed, which contained tax-related provisions. We did not experience, and do not anticipate experiencing in the near future, any meaningful impact to our tax rates from the legislation.

***Changes in accounting standards and subjective assumptions, estimates, and judgments by management related to complex accounting matters could significantly affect our financial results or financial condition.*** U.S. generally accepted accounting principles (GAAP) and related accounting pronouncements, implementation guidelines and interpretations with regard to a wide range of matters that are relevant to our business, such as asset impairment, inventories, lease obligations, self-insurance, vendor allowances, tax matters, business combinations, and legal matters, are complex and involve many subjective assumptions, estimates, and judgments. Changes in accounting standards or their interpretation or changes in underlying assumptions, estimates or judgments, could significantly change our reported or expected financial performance or financial condition. The implementation of new accounting standards could also require certain systems, internal processes, internal control, and other changes that could increase our operating costs.

***We are subject to litigation risk due to the nature of our business, which may have a material adverse effect on our business.*** From time to time, we are involved in lawsuits or other legal proceedings that arise from business transactions or the operation of our business. Due to the nature of our business, these proceedings may, for example, relate to product liability claims, commercial disputes, suits arising from our trucking operations, or employment matters. In addition, we could face claims over other matters, such as claims arising from our status as a government contractor, intellectual property matters, or corporate or securities law matters. The defense and ultimate outcome of lawsuits or other legal proceedings may result in higher operating expenses, which could have a material adverse effect on our business, financial condition, or results of operations.

***Credit and Liquidity Risks***

***Tight credit markets could impact our ability to obtain financing on reasonable terms or increase the cost of existing or future financing and interest rate fluctuations could adversely impact our results.*** As of December 31, 2025, we had $125.0 of outstanding debt obligations, all in the form of senior unsecured promissory notes issued under our master note agreement (the Master Note Agreement). The notes issued under our Master Note Agreement carry a fixed interest rate and consist of three series and are described in further detail in Note 9 of the Notes to Consolidated Financial Statements in this Form 10-K. We also have borrowing capacity under our revolving credit facility (the Credit Facility) of $835.0, but no loans were outstanding as of December 31, 2025. Loans under the Credit Facility generally bear interest at a rate per annum equal to Daily Simple Secured Overnight Financing Rate (SOFR), the rate on which may vary daily, and mature on September 28, 2027.

We currently have the capacity under the Credit Facility and Master Note Agreement to increase borrowings in the future to finance stock purchases, dividends, capital expenditures, working capital additions, acquisitions, or other investments. Should we seek to increase our borrowings during periods of volatility and disruption in the financial and credit markets, financing may become more costly and more difficult to obtain. This was not a material consideration in 2025. The cost of servicing any existing balances on the Credit Facility could increase if interest rates increase due to the SOFR-based interest rate provided for under the Credit Facility.

**ITEM 1C. CYBERSECURITY**

**Cybersecurity Risk Management and Strategy**

We have established processes and procedures for ensuring the confidentiality, integrity, and availability of data. These processes are in place to assess, identify, and manage material risks from cybersecurity threats. Annual risk assessments are performed and incorporated as part of our Enterprise Risk Management (ERM) organizational process, which is overseen by our Board of Directors (the Board) and the Audit Committee, along with Executive Leadership. Our information security management system (ISMS) program is aligned to ISO 27001, which is an international standard to manage information security. ISO 27001 is published by the International Organization for Standardization (ISO), the world's largest developer of voluntary standards, and the International Electrotechnical Commission.

Our IT security department, led by our Senior Vice President (SVP) IT Infrastructure & Security, is tasked with monitoring cybersecurity and operational risks related to information security and system disruption. The team employs measures designed to protect against, detect, and respond to cybersecurity threats, and has implemented processes and procedures aligned with our ISMS to support and promote resilient programs. This includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Enterprise security framework and cybersecurity standards;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cybersecurity awareness and training plans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Security assessments and monitoring;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Restricted physical access to critical areas, servers, and network equipment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Incident response, crisis management, business continuity, and disaster recovery plans; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Third-party IT vendor risk management process to identify, assess, and manage risks presented by our IT vendors and business partners.

Our IT security department maintains a playbook to respond to potential cybersecurity threats. We conduct tabletop exercises for tactical response readiness, perform regular security scans of our environment both from an external and internal perspective, as well as work with a qualified third-party vendor to perform penetration tests of our environment. Any identified risks are included in our overall risk management program, and internal auditors validate our IT controls on a regular basis.

We conduct organization-wide cybersecurity training and compliance exercises in connection with our information security program. This training consists of educational material and compliance testing administered to all of our employees, which is shared with Executive Leadership, the Audit Committee, and the Board. Employee phishing tests are conducted on a regular basis. Employees who do not follow protocol are redirected for additional training.

We have implemented an IT vendor risk management policy that provides guidance in managing risks associated with IT vendors and business partners. We have also established a third-party risk management program and conduct pre-onboarding security assessments and annual re-assessments of our service providers to collect, track, and manage third-party security controls based upon the risk presented to the business. Any issues identified during assessment are tracked through to remediation.

**Governance**

Our Board and Audit Committee are actively engaged in the oversight of our risk management, including cybersecurity risk. The Audit Committee receives quarterly reports on information security from our SVP IT Infrastructure & Security. Additionally, Executive Leadership is briefed on information security at least quarterly by members of our IT security, compliance, governance, and audit teams. The Audit Committee of the Board is responsible for overseeing our risk exposure to information security, cybersecurity, AI security, and data protection, as well as the steps management has taken to monitor and control such exposures.

Our IT security department, which assesses and manages our risks from cybersecurity threats, is led by our SVP IT Infrastructure & Security, who reports to our Senior EVP IT. Additional oversight for assessing and managing cybersecurity risk include Executive sponsors, IT, HR, IT Governance Risk and Compliance, Internal Audit, and Legal, as well as members of our Information Security Risk Council, IT Risk Committee, and ERM teams.

We have in place an incident response plan to identify, protect, detect, respond to, and recover from cybersecurity threats and incidents. The Information Security Risk Council, Executive Leadership, the Audit Committee, and the Board are notified of any material cybersecurity incidents through an established escalation process. Additionally, we maintain a qualified third-party vendor relationship which is available to the team for on-demand incident response and investigation, as needed.

The IT security department team members have degrees applicable to cybersecurity, including Bachelors in Information Systems, Computer Science, Management Information Systems and/or Masters in Cybersecurity, and hold professional certifications, including Certified Information Systems Security Professional, Offensive Security Certified Professional, Global

------

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

Information Assurance Certification (GIAC) Defensible Security Architecture, GIAC Forensic Examiner, GIAC Incident Handling, and GIAC Open Source Intelligence. Our SVP IT Infrastructure & Security holds a Cybersecurity and Privacy Law Certificate from Mitchell Hamline School of Law, is also a Digital Directors Network (DDN) Boardroom Certified Qualified Technology Expert (OTE), and has 30 years of experience in systems, network, and database administration. Additionally, our Senior IT security department manager is an Offensive Security Certified Professional, and holds GIAC Security Leadership (GSLC), with over 26 years of experience in network performance, availability, and protection.

**Impact of Cybersecurity Threats**

We have not identified risks from cybersecurity threats, including as a result of previous cybersecurity incidents, which have materially affected or are reasonably likely to materially affect us to date, including our business strategy, results of operations or financial condition. However, any future potential risks from cybersecurity threats, including but not limited to exploitation of vulnerabilities, ransomware, denial of service, supply chain attacks, and the use of AI by threat actors engaged in these activities, or other similar threats may materially affect us, including our execution of business strategy, reputation, results of operations and/or financial condition. For additional information regarding cybersecurity threats, see 'Item 1A. Risk Factors' of this Form 10-K.

**ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

The following is management's discussion and analysis of certain significant factors which have affected our financial position and operating results during the periods included in the accompanying consolidated financial statements and should be read in conjunction with those consolidated financial statements. This section of the Form 10-K generally discusses 2025 and 2024 items and year-to-year comparisons between the years. Discussions of 2023 comparisons can be found in our 2024 Annual Report filed with the SEC.

**Business and Operational Overview**

Fastenal is a global leader in the wholesale distribution of industrial and construction supplies. We distribute these supplies through a network of approximately 1,600 branch locations. Our largest end market is manufacturing. Sales to these customers include products for both direct materials, where our products are consumed in the final products of our customers, and indirect materials, where our products are consumed to support the facilities and ongoing operations of our customers. We also service general and commercial contractors in non-residential end markets as well as farmers, truckers, railroads, oil exploration companies, oil production and refinement companies, mining companies, federal, state, and local government entities, schools, warehouse and storage, data centers, and certain retail trades. Geographically, our selling locations and customers are primarily located in North America, though we continue to grow our non-North American presence as well.

It is helpful to appreciate several aspects of our marketplace: First, it is big and fragmented. We estimate the North American marketplace for industrial supplies is in excess of $140 billion per year (and we have expanded beyond North America) and no company has a significant portion of this market. Second, many of the products we sell are individually inexpensive, but the cost and time to manage, procure, and transport these products can be quite meaningful. Third, many customers prefer to reduce their number of indirect and direct suppliers to simplify their business, while also utilizing various technologies and models (including our local branches when they need something quickly or unexpectedly) to improve availability and reduce waste. Lastly, we believe the markets are efficient. In our view, this means that companies who grow market share are those that develop differentiated capabilities that provide the greatest value to the customer.

Our approach to addressing these aspects of our marketplace is captured in our motto ***Growth Through Customer Service***<sup>®</sup> and our tagline ***Where Industry Meets Innovation***<sup>™</sup>. The concept of growth is simple: find more customers every day that value the services we provide and increase our activity with them. However, execution is hard work. First, we recruit service-minded individuals to support customers and empower them to operate in a decentralized fashion to maximize their flexibility to solve customer problems. We support these customer-facing resources with a supply chain capability that is speedy, efficient, and cost-effective. This has formed the foundation of our high-touch model since inception. Second, we invest in, develop, and deploy capabilities that allow us to illuminate and provide greater control over a customer's supply chain. These capabilities range from service models that take advantage of our local presence and/or our ability to more efficiently manage complex procurement needs, to hardware and software technologies that promote actionable data capture, improve operating efficiencies, and reduce supply chain risk. Third, we strive to generate strong profits, which produce the cash flow necessary to support our growth, our product and technology development, and the needs of our customers.

The ultimate aim of this 'high-touch, high-tech' approach to gaining market share is to allow us to get closer to our customers, going so far as to be right to the point of consumption within customers' facilities. Marrying our presence, capabilities and technologies deepens our relationships and our understanding of our customers' day-to-day opportunities and obstacles. This, in turn, enhances our ability to provide innovative and comprehensive solutions to our customers' challenges. By doing these things every day, Fastenal remains a growth-centric organization.

The global economy continues to experience elevated levels of volatility and uncertainty, including within the commodity, labor, and transportation markets, driven by a combination of geopolitical developments and macroeconomic factors. Recent imposition of new and expanded tariffs have further contributed to disruptions in global capital markets and global supply chains. These developments may impact our operations, financial condition, and results of operations. We are actively monitoring economic conditions in the U.S. and internationally, including the potential ramifications of evolving trade policies, changes in interest rates, foreign currency exchange rate fluctuations, inflationary pressures, and the risk of a global or regional economic recession. In response to these factors, we have implemented various strategies designed to mitigate certain adverse effects of changing inflationary conditions and supply chain challenges, while continuing to maintain market price competitiveness and price/cost neutrality. Historically, our broad and diverse customer base combined with our ability to innovate with our customers have provided a degree of resilience during periods of economic contraction in the industrial market. However, the ultimate impact of ongoing macroeconomic conditions, including recent tariff-related developments, remains uncertain and cannot be predicted at this time.

Market conditions were sluggish in our key markets in 2025. The Institute for Supply Management's Purchasing Manager's Index (PMI) for the U.S. averaged 48.9 for the full year and remained below 50, the threshold demarcating manufacturing growth or contraction, in 10 out of 12 months. Business activity as measured by U.S. Industrial Production increased 1.2% in the first 11 months of 2025 over 2024. In 2025, the market provided minimal contribution, tariff related pricing contributed 170 to 200 basis points, and the primary factor contributing to our daily sales growth of 9.1% was share gains. In 2025, our growth was the result of improved customer contract signings with large key account customers and fastener products. We continued to expand our installed base of FMI technology and lift the proportion of sales that run through our Digital Footprint. In a fluid tariff environment, our gross profit was well managed. We improved our profitability, which resulted in higher incentive compensation and we invested in technology solutions to drive efficiency; however, we leveraged our SG&A expenses resulting in a 20 basis point improvement in operating margin. Asset efficiency improved from the preceding year and we generated good cash flow.

The table below summarizes our absolute and full time equivalent (FTE; based on 40 hours per week) employee headcount, number of branch locations, number of customer sites summarized by monthly spend band, and weighted FMI devices at the end of the periods presented and the percentage change compared to the end of the prior period.

---

<sup>(1)</sup>  In the fourth quarter of 2024, we realigned certain employees as a result of a routine review of our organizational structure. While there was no change to total absolute or total FTE headcount, it produced minor shifts between headcount categories. Historical numbers have been adjusted to reflect this realignment.

------

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

During the last twelve months, we increased our total FTE employee headcount by 644. Our total FTE selling personnel increased by 425 to support growth and sales initiatives to target customer acquisition. We had an increase in our distribution and transportation FTE personnel of 59 to support increased product throughput at our distribution facilities. We had an increase in our remaining FTE personnel of 160, which related primarily to personnel investments in IT, quality control, and supply chain support.

**CURRENT YEAR RESULTS ENDED 2025**

**Sales**

The table below sets forth net sales and daily sales for the periods ended December 31, and changes in such sales from the prior period to the more recent period:

---

| | | |
|:---|:---|:---|
| | **2025** | 2024 |
| Net sales | $**8200.5** | 7546.0 |
| &nbsp;&nbsp;&nbsp;Percentage change | **8.7%** | 2.7% |
| Business days | **254** | 255 |

| &nbsp;&nbsp;&nbsp;Percentage change | **9.1%** | 1.9% |
| Daily sales impact of currency fluctuations | **0.0%** | -0.1% |

---

The increase in net sales noted above for 2025 was primarily due to higher unit sales of Direct (OEM/Production) materials, Indirect (MRO/Facilities Maintenance) materials, and construction supplies. We believe higher unit sales in 2025 were primarily a result of our ability to gain market share, as most measures of industrial activity were flat to slightly up throughout the period. Despite this challenging environment, in 2025 we produced net sales growth of 8.7% and, owing to one less selling day in the period, daily sales growth of 9.1%.

We estimate the disruption to operations and logistics from severe winter weather in January 2025, while meaningful in the month of January, was not material to net sales for the full year of 2025.

Changes in product pricing resulted in 170 to 200 basis points of growth in net sales in 2025.

We effectively increased the penetration of key growth initiatives in 2025, as judged by installations and adoption, which enhanced the value we provide to our customers and supported our growth and efficiency. This was achieved through three areas. First, we signed 25,892 FMI MEUs, meeting our goal of 25,000 to 26,000 MEU. Our installed base of FMI MEUs was 136,638 at the end of 2025, an increase of 7.6% over the end of 2024. Second, we expanded the proportion of our sales running through our Digital Footprint. This measure reached 62.4% in December 2025. This was below our goal at the start of 2025, which was between 66% and 68%, attributable to lower volume through our FMI devices due to the business disruption associated with a rapidly changing tariff environment. Even so, it improved from the prior year level of 60.4% reflecting increasing internal and external adoption of our digital resources. We expect that during 2026 we will achieve 66% of our sales volume running through our Digital Footprint. Lastly, we achieved meaningful growth in both our average spend per customer site and the number of customer sites spending $5k or more per month.

From a product portfolio standpoint, we classify our offerings into three primary categories: fasteners, safety supplies, and other product lines. The 'other product lines' category encompasses eight smaller product segments, including tools, janitorial supplies, and cutting tools.

------

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

Prior to the fourth quarter of 2025, our fastener reporting focused on the segmentation of original equipment manufacturing (OEM) and maintenance, repair, and operations (MRO) fasteners. In 2024, we enhanced our analytical capabilities through significant investments in our customer master data management system, which has enabled us to deliver more granular insights into our customer site performance starting in 2025.

With continued investment in these improvements throughout 2025, starting in the fourth quarter of 2025, we are able to share a more comprehensive breakdown of our direct (OEM/production) business and our indirect (MRO/facilities maintenance) business. This extends beyond fasteners to include a broader range of product categories and gives more accurate insights into our product sales.

Direct materials are products that become incorporated into a finished good or directly support a customer's production processes. This category includes items such as production fasteners, cutting tools, abrasives, certain types of non-fasteners, hardware, and other goods essential to manufacturing throughput.

Indirect materials support customers' facility operations, maintenance, and safety needs but are not directly traceable to a finished good. These include fasteners, maintenance tools, safety solutions, janitorial supplies, and other items that sustain facility uptime and operational continuity.

The DSR change when compared to the same period in the prior year and the percent of sales in the period were as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | Twelve-month<br>DSR Change | Twelve-month<br>DSR Change | Twelve-month% of Sales | Twelve-month% of Sales |
| | **2025** | 2024 | **2025** | 2024 |
| &nbsp;&nbsp;&nbsp;&nbsp;Direct fasteners/hardware | **9.8%** | -1.8% | **20.7%** | 20.6% |
| &nbsp;&nbsp;&nbsp;&nbsp;Direct cutting tools and abrasives | **10.2%** | 3.9% | **5.2%** | 5.2% |
| &nbsp;&nbsp;&nbsp;&nbsp;Direct non-fasteners/hardware | **12.0%** | 6.7% | **12.8%** | 12.4% |
| Total direct materials | **10.6%** | 1.6% | **38.7%** | 38.2% |
| &nbsp;&nbsp;&nbsp;&nbsp;Indirect fasteners/hardware | **8.9%** | -4.5% | **9.8%** | 9.8% |
| &nbsp;&nbsp;&nbsp;&nbsp;Indirect safety | **9.4%** | 7.0% | **21.5%** | 21.4% |
| &nbsp;&nbsp;&nbsp;&nbsp;Indirect non-fasteners/hardware & non-safety | **8.1%** | 2.0% | **30.0%** | 30.6% |
| Total indirect materials | **8.7%** | 2.6% | **61.3%** | 61.8% |

---

Direct materials growth outpaced overall company growth, driven by improved availability, expanded contract penetration, and the successful implementation of new programs with large manufacturing customers that benefits direct materials more heavily oriented toward production of final goods. Increased adoption of our tailored production-line solutions contributed meaningfully to mix improvement and strengthened our position with customers.

Indirect materials growth improved, supported by ongoing demand for safety and facility-maintenance solutions. Our digital tools and inventory management programs continued to enhance customer efficiency and contributed to improved performance in this category, led by safety which benefited from growth with warehousing customers who are strong consumers of personal protective equipment.

**Annual Sales Changes, Sequential Trends, and End Market Performance**

This section focuses on three distinct views of our business – annual sales changes by month, sequential trends, and end market performance. The first discussion regarding sales changes by month provides a good mechanical view of our business. The second discussion provides a framework for understanding the sequential trends (that is, comparing a month to the immediately preceding month, and also looking at the cumulative change from an earlier benchmark month) in our business. Finally, we believe the third discussion regarding end market performance provides insight into activities with our various types of customers.

***Annual Sales Changes, by Month***

During the months noted below, all of our selling locations, when combined, had a DSR change of (compared to the same month in the preceding year):

***Sequential Trends***

**We find it helpful to think about the monthly sequential changes in our business using the analogy of climbing a stairway –** This stairway has several predictable landings where there is a pause in the sequential gain (i.e., April, July, and October to December), but generally speaking, climbs from January to October. The October landing then establishes the benchmark for the start of the next year.

History has identified these landings in our business cycle. They generally relate to months where certain holidays impair business days and/or seasons impact certain end markets, particularly non-residential construction. The first landing centers on Easter and the Good Friday holiday that precedes it, which in any given year can fall in March or April, the second landing centers on July 4th, and the third landing centers on the approach of winter with its seasonal impact on primarily our non-residential construction business and with the Christmas/New Year holidays. The holidays we noted impact the trends because they either move from month-to-month or because they move around during the week.

The table below shows the pattern to the sequential change in our daily sales. The line labeled 'Benchmark' is a historical average of our sequential daily sales change for the trailing five year average that excludes 2020. We have excluded 2020 from the average as the effects of the pandemic created unusual sequential patterns that we do not consider representative of normal trends. We believe this time frame serves to show the historical pattern and could serve as a benchmark. The '2025' and '2024' lines represent our actual sequential daily sales changes. The '25Delta' and '24Delta' lines indicate the difference between the 'Benchmark' and the actual results in the respective year. Under normal circumstances, the sequential trends shown below are directly linked to fluctuations in our end markets. Further, in any given month it is possible to get significant deviation from the benchmark.

It is important to note that these benchmarks are historical averages. In a year where demand is strong, our daily sales growth rates will tend to have more months that exceed the benchmark than fall below it. In a year where demand is weak, we will tend to have more months that fall short of the benchmark than exceed it. In both cases, there is a random element that makes it difficult to know how any single month will perform and puts greater relevance on performance trends over multiple periods.

***End Market Performance***

We estimate approximately 71% to 76% of our business is with customers engaged in some type of manufacturing, a significant subset of which finds its way into the heavy equipment market. The manufacturing environment remained sluggish in 2025. Our manufacturing end markets outperformed primarily due to the relative strength we are experiencing with key account customers with significant managed spend where our service model and technology is particularly impactful. This disproportionately benefits manufacturing customers. The DSR changes to our manufacturing customers, when compared to the same periods in the prior year, were as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| DSR change - manufacturing customers | Q1 | Q2 | Q3 | Q4 | Annual |
| **2025** | **6.8%** | **9.2%** | **12.7%** | **12.8%** | **10.4%** |
| 2024 | 2.6% | 2.7% | 3.0% | 3.3% | 2.9% |

---

We estimate approximately 24% to 29% of our business is with customers engaged in a wide range of activities, none of which individually constitute 10% of sales. This includes non-residential construction, reseller, transportation, warehouse and storage, data centers, and government/education customers. Our construction end market experienced growth starting in the second quarter of 2025 and reflected increased adoption of our solutions. Weakness within our reseller end market reflected efforts in many industries to reduce channel inventories. Our transportation end market growth moderated during the year but continued to reflect share gains with customers who manage large networks or warehouses. The DSR changes to our non-manufacturing customers, when compared to the same periods in the prior year, was as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| DSR change - non-manufacturing customers | Q1 | Q2 | Q3 | Q4 | Annual |
| **2025** | **-0.6%** | **6.7%** | **8.4%** | **6.3%** | **5.2%** |
| 2024 | 0.0% | -1.0% | -1.5% | -0.3% | -0.7% |

<u>[**Table of Contents**](#ia867aa29559847a58da1fcd6e17735fc_13)</u>

**Gross Profit**

The gross profit percentage during each period was as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| | Q1 | Q2 | Q3 | Q4 | Annual |
| **2025** | **45.1%** | **45.3%** | **45.3%** | **44.3%** | **45.0%** |
| 2024 | 45.5% | 45.1% | 44.9% | 44.8% | 45.1% |

---

Our gross profit, as a percentage of net sales, was 45.0% in 2025 and 45.1% in 2024. Our fastener expansion project and other supplier-focused initiatives offset the gross margin headwind of a continued shift toward larger customers, which typically generate higher volume at lower gross margins.

**SG&A Expenses**

SG&A expenses, as a percentage of net sales, decreased to 24.8% in 2025 from 25.1% in 2024. We continued to invest in areas such as role specialization, technology, analytics personnel, and sales-related travel that we view as critical to supporting future growth. We managed expenses not directly related to customer acquisition and growth, which allowed us to leverage SG&A expenses in 2025.

The percentage change in employee-related, occupancy-related, and all other SG&A expenses compared to the same periods in the preceding year, is outlined in the table below.

| All other SG&A expenses | 10% to 15% | **2.5%** | 8.1% |

---

Employee-related expenses include: (1) payroll (which includes cash compensation, stock option expense, and profit sharing), (2) health care, (3) personnel development, and (4) social taxes.

Our employee-related expenses increased in 2025 from 2024. This was related to: improvement in our sales and profitability generating significantly higher bonuses and commissions; higher base pay as a result of increased FTE during the period and moderate wage inflation; higher employment taxes; higher healthcare costs due to growth in the number and size of claims; and an increase in profit sharing expense reflecting improved sales and profit growth versus the prior year.

The table below summarizes the percentage change in our FTE headcount at the end of the periods presented compared to the end of the prior period:

---

| | | |
|:---|:---|:---|
| | Twelve-month Period | Twelve-month Period |
| | **2025** | 2024 <sup>(1)</sup> |
| Selling personnel <sup>(2)</sup> | **2.8%** | 0.0% |
| Distribution/Transportation personnel | **2.0%** | 2.5% |
| Manufacturing personnel | **2.4%** | 8.0% |
| Organizational support personnel <sup>(3)</sup> | **6.9%** | 5.2% |
| &nbsp;&nbsp;&nbsp;&nbsp;Total personnel | **3.1%** | 1.1% |

---

<sup>(1)</sup>  In the fourth quarter of 2024, we realigned certain employees as a result of a routine review of our organizational structure. While there was no change to total absolute or total FTE headcount, it produced minor shifts between headcount categories. Historical numbers have been adjusted to reflect this realignment.

<sup>(2)</sup>  Of our Selling Personnel, 80%-85% are attached to a specific selling location.

<sup>(3)</sup>  Organizational support personnel consists of: (1) Sales Support personnel (37% to 42% of category), which includes sourcing, purchasing, supply chain, product development, etc.; (2) IT personnel (34% to 39% of category); and (3) Administrative Support personnel (22% to 27% of category), which includes HR, FSB, accounting and finance, senior management, etc.

Occupancy-related expenses include: (1) building rent and depreciation, (2) building utility costs, (3) equipment related to our branches and distribution locations, and (4) industrial vending equipment and bins utilized as part of FMI services (we consider this hardware to be a logical extension of our operations and classify the depreciation and repair costs as occupancy expenses).

Our occupancy-related expenses increased in 2025 from 2024. This was related to: inflation in branch rent expense, increased FMI depreciation as the number of installed devices increased; higher costs and depreciation for the maintenance, upgrade, and installation of equipment in hub and non-hub facilities; and an increase in property taxes.

All other SG&A expenses include: (1) selling-related transportation, (2) IT expenses, (3) general corporate expenses, which consists of legal expenses, general insurance expenses, travel and marketing expenses, etc., and (4) sales of property and equipment.

Combined, all other SG&A expenses increased in 2025 from 2024. This was related to the following increases: higher spending on IT, increased sales expense associated with signing and implementing customer sites, and selling-related transportation costs increased and were only partially offset by lower fuel expense. The increases were partially offset by increases in shared marketing initiatives with our suppliers and lower general insurance costs.

**Net Interest**

Interest income slightly increased in 2025 and we had lower interest expense in 2025. We carried lower average borrowings relative to 2024 primarily from cash generated from higher net earnings enabling us to reduce outstanding revolver debt under the Credit Facility. The slight increase in interest income and the reduction in interest expense resulted in net interest expense of $0.7 in 2025 compared to $1.9 in 2024.

**Income Taxes**

We recorded income tax expense of $396.6 in 2025, or 24.0% of income before income taxes. Income tax expense was $357.5 in 2024, or 23.7% of income before income taxes. We believe our ongoing tax rate, absent any discrete tax items or broader changes to tax law, will be approximately 24.5%.

**Net Income**

Net income, net income per share, the percentage change in net income, and the percentage change in net income per share, were as follows:

---

| | | |
|:---|:---|:---|
| Dollar Amounts | **2025** | 2024 |
| Net income | $**1258.4** | 1150.6 |
| Basic net income per share | **1.10** | 1.00 |
| Diluted net income per share | **1.09** | 1.00 |
| Percentage Change | **2025** | 2024 |
| Net income | **9.4%** | -0.4% |
| Basic net income per share | **9.2%** | -0.6% |
| Diluted net income per share | **9.2%** | -0.6% |
|  | **2025** | 2024 |
| Tax Rate | **24.0%** | 23.7% |

---

During 2025, net income per share increased. Volume growth in 2025 was sufficient to produce SG&A leverage that could offset mix-related gross margin contraction, resulting in operating margin expansion.

**Liquidity and Capital Resources**

***Net Cash Provided by Operating Activities***

Net cash provided by operating activities in dollars and as a percentage of net income were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | Five-Year Average <sup>(1)</sup> | **2025** | 2024 |
| **Net cash provided** | $1083.8 | $**1295.9** | 1173.3 |
| &nbsp;&nbsp;&nbsp;&nbsp;*% of net income* | *104.8 %* | ***103.0*** *%*** | *102.0 %* |

---

<sup>(1)</sup> Five-year average includes 2020 to 2024.

In 2025, we experienced a slight increase in our operating cash flow as a percentage of net income. The increase in operating cash flow, as a percent of net income, primarily reflects our operating assets and liabilities being a slightly less use of cash in 2025 as compared to 2024. This was attributable to an increase in accounts receivable reflecting increased sales activity, partially offset by a lower investment in inventory at the end of the period.

| Net sales in last three months | $**2027.4** | 202.9 | 11.1% |

---

Note – Amounts may not foot due to rounding.

The increase in our accounts receivable balance in 2025 was primarily attributable to growth in sales to our customers.

Our inventory balances over time will respond to business activity, though various factors produce a looser relationship to our monthly sales patterns than we tend to experience in accounts receivable. One reason for this is because it is cyclical. We source significant quantities of product from overseas, and the lead time involved in procuring these products is typically longer than the visibility we have into future monthly sales patterns. As a result, trends in our inventory will often lag trends in economic conditions. A second reason relates to product cost and the length of our supply chain. A significant proportion of our products, particularly fasteners, are sourced from Asia and transported primarily by ship and rail to our North American network for sale. This requires us to purchase a meaningful quantity of our products months in advance of those products being available for sale in our North American facilities and the cost of these products can be meaningfully impacted by changes in tariffs. Product that is in transit is in our inventory but is not available for sale, which can create a lag in our ability to adjust inventory levels or costs in response to rapid changes in economic or cost conditions. A third factor that tends to require incremental inventory increases over time is our growth drivers, including our FMI offerings, customer contract signings, and international expansion, all of which tend to require significant investments in inventory.

The increase in our inventory balance in 2025 was primarily attributable to four factors. First, our inventory increased as a result of growth in sales to our customers and the addition of stock to ensure we can support our customers' future growth. Second, we added stock to improve service to our selling locations and generate efficiencies in our hubs. Third, we took advantage of year-end opportunities arising from our suppliers' desire to reduce inventory at year-end. Fourth, incremental tariffs enacted in 2025 meaningfully increased the cost of certain inventory.

The increase in our accounts payable balance in 2025 was primarily attributable to an increase in our product purchases as reflected in the growth in inventories.

The approximate percentage mix of inventory stocked at our selling locations versus our distribution center and manufacturing locations was as follows at year end:

---

| | | |
|:---|:---|:---|
| | **2025** | 2024 |
| Selling locations | **54%** | 59% |
| Distribution center and manufacturing locations | **46%** | 41% |
| &nbsp;&nbsp;&nbsp;&nbsp;Total | **100%** | 100% |

---

***Lease Obligations***

We have facilities, equipment, and vehicles leased under operating leases. A discussion of our lease obligations is contained in Note 8 of the Notes to Consolidated Financial Statements.

***Net Cash Used in Investing Activities***

Net cash used in investing activities in dollars and as a percentage of net income were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | Five-Year Average <sup>(1)</sup> | **2025** | 2024 |
| **Net cash used** | $193.8 | $**231.0** | 214.5 |
| &nbsp;&nbsp;&nbsp;&nbsp;*% of net income* | *19.3 %* | ***18.4*** *%*** | *18.6 %* |

---

<sup>(1)</sup> Five-year average includes 2020 to 2024.

Our net cash used in investing activities increased in 2025 from 2024. This increase was primarily related to investments for net capital expenditures.

Our capital spending typically falls into five categories: (1) purchases related to FMI hardware, (2) purchases of property and equipment related to expansion of and enhancements to distribution centers, owned or leased branch properties, and other company facilities, (3) spending on software and hardware for our information processing systems, (4) the addition of fleet vehicles, and (5) the addition of manufacturing equipment. Proceeds from the sales of property and equipment, typically for the planned disposition of pick-up trucks as well as distribution vehicles and trailers in the normal course of business, are netted against these purchases and additions.

Set forth below is a recap of our 2025 and 2024 net capital expenditures in dollars and as a percentage of net sales and net income:

---

| | | |
|:---|:---|:---|
| | **2025** | 2024 |
| Manufacturing, warehouse and packaging equipment, industrial vending equipment, and facilities | $**160.1** | 145.8 |
| Shelving and related supplies for selling location openings and for product expansion at existing selling locations | **27.3** | 23.5 |
| Data processing software and equipment | **34.7** | 25.5 |
| Real estate and improvements to branch locations | **6.9** | 8.7 |
| Vehicles | **16.3** | 23.0 |
| &nbsp;&nbsp;&nbsp;&nbsp;Purchases of property and equipment | **245.3** | 226.5 |
| Proceeds from sale of property and equipment | **(14.8)** | (12.4) |
| &nbsp;&nbsp;&nbsp;&nbsp;**Net capital expenditures** <sup>(1)</sup> | **230.6** | 214.1 |
| &nbsp;&nbsp;&nbsp;&nbsp;*% of net sales* | ***2.8*** *%*** | *2.8 %* |
| &nbsp;&nbsp;&nbsp;&nbsp;*% of net income* | ***18.3*** *%*** | *18.6 %* |

---

<sup>(1)</sup> Amounts may not foot due to rounding.

Our net capital expenditures in 2025 increased when compared to 2024, though they were below our anticipated range of $235.0 to $255.0 for the year. The increase in capital spend from 2024 primarily related to an increase in spending for FMI hardware to support growth in our installed base and IT. We were below our anticipated range due to delayed projects that are expected to resume in 2026. Our five-year average of investment in property and equipment, as a percentage of net sales is 2.5%.

For 2026, we expect our investment in property and equipment, net of proceeds from sales, to be within a range of $310.0 to $330.0, an increase from $230.6 in 2025. The expected growth on a year-to-year basis reflects three items. First, we expect increased spending to replace our Atlanta hub facility and improve our picking capacity and efficiency across our hub network. Second, we expect increased trucking spend. Third, we expect elevated IT spending as projects that were expected in 2025 experienced delays and are expected to continue throughout 2026.

***Net Cash Used in Financing Activities***

Net cash used in financing activities in dollars and as a percentage of income were as follows:

---

| | | |
|:---|:---|:---|
| | **2025** | 2024 |
| Cash dividends paid | $**1004.2** | 893.3 |
| &nbsp;&nbsp;&nbsp;&nbsp;*% of net income* | ***79.8*** *%*** | *77.6 %* |
| &nbsp;&nbsp;&nbsp;&nbsp;Total returned to shareholders | $**1004.2** | 893.3 |
| &nbsp;&nbsp;&nbsp;&nbsp;*% of net income* | ***79.8*** *%*** | *77.6 %* |
| Proceeds from the exercise of stock options | $**(24.3)** | (39.6) |
| &nbsp;&nbsp;&nbsp;&nbsp;*% of net income* | ***-1.9*** *%*** | *-3.4 %* |
| Debt obligations payments (proceeds), net | $**75.0** | 60.0 |
| &nbsp;&nbsp;&nbsp;&nbsp;*% of net income* | ***6.0*** *%*** | *5.2 %* |
| &nbsp;&nbsp;&nbsp;&nbsp;Net cash used | $**1054.9** | 913.7 |

---

The increase in net cash used in financing activities reflects two factors. First, we had higher dividend payments. We increased regular dividend payments in 2025 by 12.4%. Second, we used more cash to reduce outstanding debt obligations in 2025 than we did in 2024. These uses of cash were only partly offset by a decrease in the exercise of stock options.

***Dividends***

We declared a quarterly dividend of $0.240 per share on January 16, 2026. In 2025, we paid aggregate annual dividends per share of $0.875. In 2024, we paid aggregate annual dividends per share of $0.780.

***Stock Purchases***

We did not purchase any of our common stock in 2025 or 2024.

We have authority to purchase up to 12,400,000 shares of our common stock under the July 12, 2022 authorization. This authorization does not have an expiration date.

***Debt***

In order to fund the considerable cash needed to expand our industrial vending business, expand capacity and increase the use of automation in our distribution centers, and pay dividends, we have borrowed under the Credit Facility and our Master Note Agreement historically.

Our borrowings under the Credit Facility and Master Note Agreement peaked during each quarter of 2025 as follows:

---

| | |
|:---|:---|
| Peak borrowings | **2025** |
| First quarter | $**320.0** |
| Second quarter | **365.0** |
| Third quarter | **265.0** |
| Fourth quarter | **185.0** |

---

As of December 31, 2025, we had $0.0 outstanding under the Credit Facility and had contingent obligations from letters of credit outstanding under the Credit Facility in an aggregate face amount of $29.7. As of December 31, 2025, we had loans outstanding under the Master Note Agreement of $125.0. Descriptions of the Credit Facility and Master Note Agreement are contained in Note 9 of the Notes to Consolidated Financial Statements.

***Material Cash Requirements***

Our material cash requirements for known contractual obligations include capital expenditures, debt, and lease obligations, each of which are discussed in more detail earlier in this section. We believe that net cash provided by operating activities will be adequate to meet our liquidity and capital needs for these items in the short-term over the next 12 months and also in the long-term beyond the next 12 months. We also have cash requirements for purchase orders and contracts for the purchase of inventory and other goods and services, which are based on current distribution needs and are fulfilled by our suppliers within short time horizons. We do not have significant agreements for the purchase of inventory or other goods or services specifying minimum order quantities. In addition, we may have liabilities for uncertain tax positions but we do not believe any of these liabilities will be material. A discussion of income taxes is contained in Note 7 of the Notes to Consolidated Financial Statements.

**Unremitted Foreign Income**

Approximately $177.5 of cash and cash equivalents were held by non-U.S. subsidiaries on December 31, 2025. These funds may create foreign currency translation gains or losses depending on the functional currency of the entity holding the cash. We have considered the financial requirements of each foreign subsidiary and our parent company and will continue to reinvest these funds to support our expansion activities outside the U.S., even after taking into consideration the deemed repatriation and transition tax under the Tax Cuts and Jobs Act. The income tax impact of repatriating cash associated with investments in foreign subsidiaries is discussed in Note 7 of the Notes to Consolidated Financial Statements.

**Effects of Inflation**

We observed inflationary conditions in 2025, primarily related to the implementation of incremental tariffs on imported products. Steel and aluminum products and derivatives had the highest increases. We implemented pricing actions to address the incremental tariffs beginning in the second quarter of 2025. The combined net effect on our gross profit percentage of these trends in cost and price inflation was immaterial in 2025.

**Critical Accounting Estimates**

In preparing our consolidated financial statements in conformity with U.S. GAAP, we must make decisions that impact the reported amounts of assets, liabilities, sales, and expenses, and the related disclosures. Such decisions include the selection of the appropriate accounting principles to be applied and the assumptions on which to base accounting estimates. In reaching such decisions, we apply judgments based on our understanding and analysis of relevant circumstances, historical experience, and actuarial valuations. Actual amounts could differ from those estimated at the time the consolidated financial statements are prepared.

Our most significant accounting policies, including Revenue Recognition and Inventories, are described in Note 1 of the Notes to Consolidated Financial Statements. Some of those significant accounting policies require us to make difficult, subjective, or complex judgments, or estimates. An accounting estimate is considered to be critical if it meets both of the following criteria: (i) the estimate requires assumptions about matters that are highly uncertain at the time the accounting estimate is made, and (ii) different estimates reasonably could have been used, or changes in the estimate that are reasonably likely to occur from period to period may have a material impact on the presentation of our financial condition, changes in financial condition, or results of operations. Our most critical accounting estimates include the following:

*Inventory valuation* – We record inventory at the lower of cost or net realizable value. We record valuation adjustments for excess, slow-moving, and obsolete inventory that are equal to the difference between the cost and estimated net realizable value for that inventory. Valuation adjustments are estimated using an evaluation of product demand, market conditions, condition of the inventory, or liquidation value. As the inventory valuation requires significant judgment, we deem it a critical accounting estimate. Historically, actual valuation adjustments have not varied materially from estimated amounts. We do not believe there is a reasonable likelihood of a material change in the estimates or assumptions we used to value our inventory in 2025.

*General insurance reserves* – We record reserves for general claims related to workers' compensation, property and casualty losses, and other general liability self-insured losses. These reserves are based on reported claims and estimated claims incurred but not yet reported, using historical claim trends, loss development patterns, management's understanding of current environment and economic factors, and data provided by external specialists and insurance carriers. We update annual booking rates using historical claims data and reassess the reserve throughout the year. As the estimation of insurance reserves requires significant judgment, we deem it a critical accounting estimate. Historically, actual reserve adjustments have not varied materially from estimated amounts. We do not believe there is a reasonable likelihood of a material change in the estimates or assumptions we use to value our insurance reserves in 2025.

**Recently Issued and Adopted Accounting Pronouncements**

A description of recently issued and adopted accounting pronouncements, if any, is contained in Note 1 of the Notes to Consolidated Financial Statements.

**ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

We are exposed to certain market risks from changes in tariffs and import shipping costs, commodity steel prices, commodity energy prices, foreign currency exchange rates, and interest rates as described in Item 1A above. Changes in these factors cause fluctuations in our income and cash flows. We evaluate and manage exposure to these market risks as follows:

**Tariffs and import shipping costs** – We import a significant quantity of our products from foreign suppliers, primarily from Asia. These imports are both direct, where we procure directly from a foreign producer, and indirect, where we purchase from a domestic supplier that produces or supplies the product we purchase from foreign locations. The current U.S. presidential administration has implemented tariffs on imports from a number of countries which have increased the cost of our products. Additionally, we incur costs related to shipping charges, duties, harbor fees, and sundry other expenses involved in the movement of product for sale in North America and our other global locations. These costs are embedded in our product values and significant fluctuations can affect our product gross profit. Fluctuations in the cost of tariffs and overseas shipping containers can be affected by the length of our supply chain, contractually agreed upon rates, or differences in rates between routes. We endeavor to offset these impacts in our business by appropriately considering them in our pricing and operational models. We estimate the effect on our net income related to tariffs and import shipping costs was immaterial in 2025; however, our tariff exposure may become more impactful in subsequent quarters as our lower tariff inventory is depleted and replaced with inventory that is subject to new and expanded tariffs.

**Commodity steel prices** – We buy and sell various types of steel products; these products consist primarily of different types of fasteners and related hardware. We are exposed to the impacts of commodity steel pricing and our related ability to pass through the impacts to our end customers. During 2025, the price of steel as reflected in many market indexes most relevant to our business was higher than the prior year. Due to our long supply chain, changes in the cost of steel can take a number of quarters to be reflected in our financial results. Further, the cost of the raw material is generally a smaller part of the total value of the steel products that we sell, which can also diminish the impact of cost changes for the raw material. We estimate the effect on our net income related to commodity steel prices was immaterial in 2025.

**Commodity energy prices** – We have market risk for changes in prices of oil, gasoline, diesel fuel, natural gas, and electricity, largely due to our consumption of fuel in our vehicles and utility costs at our facilities. As reflected in many market indexes, energy prices during 2025 on average were above the prior year. Total direct fuel consumption is a relatively smaller cost to us and, as a result, we estimate the effect on our net income related to commodity energy prices was immaterial in 2025.

Fossil fuels are also often a key feedstock for chemicals and plastics that comprise a key raw material for many products that we sell. During 2025, prices for fossil fuels were below the prior year. The cost of the raw material is generally a smaller part of the total value of the products that we sell, which can diminish the impact of cost changes for the raw material. As a result, we estimate the effect on our net income related to materials for which fossil fuels are a feedstock was immaterial in 2025.

**Foreign currency exchange rates** – Foreign currency fluctuations can affect our operations in countries other than the U.S., and/or the value of income and assets denominated in foreign currencies. Our primary currency exposures are the Canadian dollar and the Mexican peso against the U.S. dollar, reflecting the scale of those operations relative to the size of our business. Changes in foreign currency rates have not historically had a material effect on our results due to certain jurisdictions conducting some portion of their transactions in U.S. dollars and our foreign operations typically having sales and expenses denominated in the applicable local currency. As a result, we have not historically hedged our foreign currency risk. The dollar strengthened in 2025 relative to other foreign currencies in which we operate. However, the effect of these changes in foreign currencies to our net income was immaterial in 2025.

**Interest rates** – Loans under the Credit Facility bear interest at floating rates. As a result, changes in such rates can affect our operating results and liquidity to the extent we do not have effective interest rate swap arrangements in place. Our debt levels are relatively small; therefore, we have not historically used interest rate swap arrangements to hedge the variable interest rates under the Credit Facility. A one percentage point increase to our floating rate debt in 2025 would have resulted in approximately $0.4 of additional interest expense. A description of the Credit Facility is contained in Note 9 of the Notes to Consolidated Financial Statements.

**ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA**

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Board of Directors and Stockholders of Fastenal Company

*Opinions on the Financial Statements and Internal Control over Financial Reporting*

We have audited the accompanying consolidated balance sheet of Fastenal Company and its subsidiaries (the "Company") as of December 31, 2025, and the related consolidated statements of income, of comprehensive income, of stockholders' equity and of cash flows for the year then ended, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

*Basis for Opinions*

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audit of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

*Definition and Limitations of Internal Control over Financial Reporting*

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

*Revenue Recognition*

As described in Note 1 to the consolidated financial statements, net sales include products and shipping and handling charges, net of estimates for product returns and any related sales incentives. The Company recognizes revenue when or as the Company satisfies its performance obligations by transferring control of the promised products to the customer, which primarily occurs when products are delivered or picked up by the customer. For the year ended December 31, 2025, the Company's net sales were $8,200.5 million.

The principal consideration for our determination that performing procedures relating to revenue recognition is a critical audit matter is a high degree of auditor effort in performing procedures related to the Company's revenue recognition.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process. These procedures also included, among others, evaluating certain revenue transactions by either (i) testing the issuance and settlement of invoices; tracing transactions not settled to a detailed listing of accounts receivable; testing the completeness and accuracy of data provided by management; and confirming a sample of outstanding customer invoice balances as of December 31, 2025 and, for confirmations not returned, obtaining and inspecting source documents, such as evidence of customer arrangement, invoices, delivery documents, and subsequent cash receipts; or (ii) testing, on a sample basis, the revenue recognized by obtaining and inspecting source documents, such as evidence of customer arrangement, invoices, delivery documents, and subsequent cash receipts.

Fastenal Company:

*Opinions on the Consolidated Financial Statements*

We have audited the accompanying consolidated balance sheet of Fastenal Company and subsidiaries (the Company) as of December 31, 2024, the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows for each of the years in the two-year period ended December 31, 2024, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and the results of its operations and its cashflows for each of the years in the two-year period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.

*Basis for Opinions*

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB.

**Fastenal Company**

**Notes to Consolidated Financial Statements**

**Note 1. Business Overview and Summary of Significant Accounting Policies**

***Business Overview***

Fastenal is a leader in the wholesale distribution of industrial and construction supplies. We distribute these supplies through a network of selling locations located primarily in North America.

***Principles of Consolidation***

The consolidated financial statements include the accounts of Fastenal Company and its subsidiaries (the 'Company,' 'Fastenal,' 'we,' 'our,' or 'us'). All material intercompany balances and transactions have been eliminated in consolidation.

***Stock Split***

On April 23, 2025, we announced a two-for-one stock split of our outstanding common stock. Holders of the Company's common stock, par value $0.01 per share, at the close of business on May 5, 2025, received one additional share of common stock for every share of common stock they owned. The stock split took effect at the close of business on May 21, 2025. All historical common stock share, per share information, stock option awards, and stockholders' equity balances for all periods presented have been retroactively adjusted to reflect the two-for-one stock split.

***Revenue Recognition***

Net sales include products and shipping and handling charges, net of estimates for product returns and any related sales incentives. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products. All revenue is recognized when or as we satisfy our performance obligations under the contract. We recognize revenue by transferring control of the promised products to the customer, which primarily occurs when products are delivered or picked up by the customer. We recognize revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. We estimate product returns based on historical return rates and lag. Using probability assessments, which are based on known inputs at year-end, we estimate sales incentives expected to be paid over the term of the contract. The majority of our contracts have a single performance obligation and are short-term in nature. Sales taxes and value-added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales.

***Accounts Receivable***

Credit is extended based upon an evaluation of the customer's financial condition. Accounts receivable are stated at their estimated net realizable value. The allowance for credit losses is based on a historical loss experience approach which adjusts the ending balance sheet to take into consideration expected losses over the contractual lives of the receivables, considering factors such as historical data as a basis for future expected losses.

***Foreign Currency Translation and Transactions***

The functional currency of our foreign operations is typically the applicable local currency. The functional currency is translated into U.S. dollars for balance sheet accounts, except retained earnings, using current exchange rates as of the balance sheet date, for retained earnings at historical exchange rates, and for sales and expense accounts using a weighted average exchange rate during the applicable period. The translation adjustments are deferred as a separate component of stockholders' equity captioned accumulated other comprehensive loss. Gains or losses resulting from transactions denominated in foreign currencies are included in cost of sales or SG&A expenses.

***Cash and Cash Equivalents***

We consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.

***Inventories***

Inventories, which consist of finished goods merchandise that is held for resale, are stated at the lower of cost (first in, first out method) or net realizable value. We record valuation adjustments for excess, slow-moving, and obsolete inventory that are equal to the difference between the cost and estimated net realizable value for that inventory. These estimates are based on a review and comparison of the current inventory levels to projected and historical sales of inventory.

***Property and Equipment***

Property and equipment are stated at cost. Depreciation on property and equipment is provided for using the straight-line method over the anticipated economic useful lives of the related property.

**Fastenal Company**

**Notes to Consolidated Financial Statements (Continued)**

***Leases***

We determine if an arrangement contains a lease at inception. Operating leases are included in our operating lease right-of-use (ROU) assets, the current portion of operating lease liabilities, and the operating lease liabilities in our Consolidated Balance Sheets.

The ROU assets represent our right to control the use of an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The operating lease ROU assets also include any prepaid lease payments made and exclude lease incentives. Lease expense is recognized on a straight-line basis over the lease term.

Many of our leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases. Our pick-up truck leases typically have a non-cancelable lease term of less than one year and therefore, we have elected the practical expedient to exclude these short-term leases from our ROU assets and lease liabilities.

Most leases include one or more options to renew. The exercise of lease renewal options is typically at our sole discretion; therefore, the majority of renewals to extend the lease terms are not included in our ROU assets and lease liabilities as they are not reasonably certain of exercise. We regularly evaluate the renewal options and when they are reasonably certain of exercise, we include the renewal period in our lease term.

As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. We have a centrally managed treasury function; therefore, based on the applicable lease terms and the current economic environment, we apply a portfolio approach for determining the incremental borrowing rate.

***Long-Lived Assets***

Long-lived assets consist of net property and equipment, operating lease ROU assets, prepaid deposits, goodwill, and definite-lived intangible assets. Other than goodwill, these are reviewed for impairment whenever an event or change in circumstance indicates that the carrying amount of the asset group may not be recoverable. If circumstances require an asset group to be tested for possible impairment, we first compare undiscounted cash flows expected to be generated by the asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values, and third-party independent appraisals, as necessary. There were no impairments recorded during any of the three years reported in these consolidated financial statements.

Goodwill represents the excess of the purchase price over the fair value of net assets acquired. Goodwill is reviewed for impairment annually or more frequently if triggering events occur. The identifiable intangible assets are amortized on a straight-line basis over their estimated lives.

***Accounting Estimates***

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, sales and expenses, and the disclosure of contingent liabilities. Actual results could differ from those estimates.

***Insurance Reserves***

We are self-insured for certain losses relating to workers' compensation, automobile, health, and general liability costs. Specific stop-loss coverage is provided for catastrophic claims in order to limit exposure to significant claims. Self-insurance liabilities are based on our estimate of reported claims and claims incurred but not yet reported. We analyze historical trends, claims experience, and loss development patterns to ensure the appropriate loss development factors are applied to the incurred costs associated with the claims made.

**Fastenal Company**

**Notes to Consolidated Financial Statements (Continued)**

***Product Warranties***

We offer a basic limited warranty for certain of our products. The specific terms and conditions of those warranties vary depending upon the product sold. We typically recoup these costs through product warranties we hold with the original equipment manufacturers. Our warranty expense has historically been immaterial.

***Stock-Based Compensation***

We estimate the fair value of stock options as of the grant date using a Black-Scholes valuation model. Stock-based compensation expense equal to the grant date fair value is recognized on a straight-line basis over the vesting period. Our stock-based compensation expense is recorded in SG&A expenses.

***Income Taxes***

We account for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We recognize the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We record interest and penalties related to unrecognized tax benefits in income tax expense.

***Net Income Per Share***

Basic net income per share is calculated using net income available to common stockholders divided by the weighted average number of shares of common stock outstanding during the year. Diluted net income per share is similar to basic net income per share except that the weighted average number of shares of common stock outstanding includes the incremental shares assumed to be issued upon the exercise of stock options considered to be 'in-the-money' (i.e., when the market price of our stock is greater than the exercise price of our outstanding stock options).

***Recently Adopted Accounting Pronouncements***

In December 2023, the Financial Accounting Standards Board ('FASB') issued Accounting Standards Update ('ASU') 2023-09, *Improvements to Income Tax Disclosures* (Topic 740), which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. The new guidance requires consistent categorization and greater disaggregation of information in the income tax rate reconciliation, as well as further disaggregation of income taxes paid. We adopted ASU 2023-09 for the year ended December 31, 2025 and have applied the guidance retrospectively for all periods presented within the notes to the consolidated financial statements. The adoption of ASU 2023-09 did not have a material impact on our consolidated financial statements for the year ended December 31, 2025, but did require additional disclosures. Refer to Note 7 for additional information.

***Recently Issued Accounting Pronouncements***

In November 2024, the FASB issued ASU 2024-03, *Disaggregation of Income Statement Expenses (DISE)*, which specifies additional disclosure requirements, including the composition of certain income statement expense line items (such as purchases of inventory, employee compensation, and 'other expenses') and a separate disclosure for selling expenses. This change is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027, however, early adoption is permitted. We are currently evaluating the impact that the adoption of ASU 2024-03 will have on our consolidated financial statements and disclosures and anticipate adoption in 2027.

**Note 5. Stockholders' Equity**

***Dividends***

On January 16, 2026, our board of directors declared a quarterly dividend of $0.24 per share of common stock to be paid in cash on February 26, 2026 to shareholders of record at the close of business on January 29, 2026. In 2025, we paid aggregate annual cash dividends per share of $0.875. We paid aggregate annual cash dividends per share of $0.78 and $0.89 in 2024 and 2023, respectively. In 2023, this included a special dividend of $0.19 per share paid in the fourth quarter.

***Stock Options***

Effective January 2, 2026, the compensation committee of our board of directors granted to our employees options to purchase a total of 1,339,070 shares of our common stock at an exercise price of $41.00 per share. On the same date, certain of our non-employee directors received options to acquire a total of 169,011 shares of our common stock at an exercise price of $41.00 per share. The closing stock price on the effective date of the grants was $40.44 per share.

The following tables summarize the details of options granted under our stock option plans that were still outstanding as of December 31, 2025, and the assumptions used to value those grants. All such grants were effective at the close of business on the grant date.

All of the options in the tables above vest and become exercisable over a period of up to eight years. Each option will terminate approximately 10 years after the grant date.

The fair value of each share-based option is estimated on the grant date using a Black-Scholes valuation method that uses the assumptions listed above. The risk-free interest rate is based on the U.S. Treasury rate over the expected life of the option at the time of grant. The expected life is the average length of time over which we expect the employee groups will exercise their options, net of cancellations, which is based on historical experience with similar grants. The dividend yield is estimated over the expected life of the option based on our current dividend payout, historical dividends paid, and expected future cash dividends. Expected stock volatility is based on the movement of our stock price over the most recent historical period equivalent to the expected life of the option.

<sup>(1)</sup> Weighted average exercise price.

<sup>(2)</sup> Weighted average remaining contractual life in years.

The total intrinsic value of stock options exercised during the years ended December 31, 2025, 2024, and 2023 was $34.6, $57.6, and $38.1, respectively. The intrinsic value represents the difference between the exercise price and fair value of the underlying shares at the date of exercise.

At December 31, 2025, there was $20.0 of total unrecognized stock-based compensation expense related to outstanding unvested stock options granted under the employee stock option plan. This expense is expected to be recognized over a weighted average period of 3.95 years. Any future change in estimated forfeitures will impact this amount. The total grant date fair value of stock options vested under our employee stock option plan during 2025, 2024, and 2023 was $7.1, $7.6, and $5.3, respectively.

Total stock-based compensation expense related to our employee stock option plan was $8.4, $8.0, and $7.3 for 2025, 2024, and 2023, respectively. There is no incremental stock-based compensation expense as a result of the stock split described in Note 1.

**Note 6. Retirement Savings Plan**

The Fastenal Company and Subsidiaries 401(k) and Employee Stock Ownership Plan covers all of our employees in the U.S. Our employees in Canada may participate in a Registered Retirement Savings Plan. The general purpose of both of these plans is to provide additional financial security during retirement by providing employees with an incentive to make regular savings contributions. In addition to the participation of our employees, we make annual profit sharing contributions based on an established formula. The expense recorded under this profit sharing formula was approximately $23.5, $20.8, and $23.1 for 2025, 2024, and 2023, respectively.

A reconciliation of the beginning and ending amount of total gross unrecognized tax benefits is as follows:

---

| | | |
|:---|:---|:---|
| | **2025** | 2024 |
| Balance at beginning of year | $**9.9** | 10.2 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Increase related to prior year tax positions | **0.7** | 1.1 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Increase related to current year tax positions | **0.4** | 0.4 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Decrease related to statute of limitation lapses | **(2.5)** | (1.8) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Decrease related to prior year tax positions | **(6.3)** |  |
| Balance at end of year | $**2.2** | 9.9 |

---

Included in the liability for gross unrecognized tax benefits is $0.2 as of December 31, 2025 and $4.2 as of December 31, 2024 for interest and penalties, both of which we classify as a component of income tax expense. The amount of unrecognized tax benefits that would favorably impact the effective tax rate, if recognized, is $1.7 as of December 31, 2025 and $9.1 as of December 31, 2024. The 2025 and 2024 liability is included in deferred income taxes in the Consolidated Balance Sheets.

We file income tax returns in the U.S. federal jurisdiction, all states, and various local and foreign jurisdictions. We are no longer subject to income tax examinations by taxing authorities for taxable years before 2022 in the case of U.S. federal examinations, and with limited exception, before 2020 in the case of foreign, state, and local examinations.

In general, it is our practice and intention to permanently reinvest the income of our foreign subsidiaries and repatriate income only when the tax impact is zero or very minimal. Accordingly, no deferred taxes have been provided for withholding taxes or other taxes that would result upon repatriation of our approximately $625.3 of undistributed income from foreign subsidiaries to the U.S. as that income continues to be permanently reinvested. It is not practicable to estimate the amount of unrecognized deferred tax liability on these undistributed earnings because of complexities of tax laws, the hypothetical calculation and the significant assumptions required regarding future repatriation strategies.

**Note 8. Operating Leases**

We lease space under non-cancelable operating leases for several distribution centers, several manufacturing locations, and certain branch locations. These leases do not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the leases do not contain contingent rent provisions. We also lease certain semi-tractors, pick-up trucks, and computer equipment under operating leases.

Certain operating leases for pick-up trucks contain residual value guarantee provisions which would generally become due at the expiration of the operating lease agreement if the fair value of the leased vehicles is less than the guaranteed residual value. The aggregate residual value guarantee related to these leases was approximately $124.2. We believe the likelihood of funding the guarantee obligation under any provision of the operating lease agreements is remote.

The cost components of our operating leases were as follows for the periods ended December 31:

---

Variable lease costs are excluded from ROU assets and lease liabilities and consist primarily of taxes, insurance, and common area or other maintenance costs for our leased facilities and equipment which are paid based on actual costs incurred by the lessor as well as variable mileage costs related to our leased vehicles.

Maturities of our lease liabilities for all operating leases were as follows as of December 31, 2025:

**Unsecured Revolving Credit Facility** 

We have an $835.0 committed unsecured revolving Credit Facility with an uncommitted accordion option to increase the aggregate revolving commitment by an additional $365.0 for a total of $1,200.0. The Credit Facility includes a committed letter of credit subfacility of $55.0. Any borrowings outstanding under the Credit Facility for which we have the ability and intent to pay using cash within the next 12 months will be classified as a current liability. The Credit Facility contains certain financial and other covenants, and our right to borrow under the Credit Facility is conditioned upon, among other things, our compliance with these covenants. We are currently in compliance with these covenants.

Borrowings under the Credit Facility generally bear interest at a rate per annum equal to Daily Simple SOFR plus a 0.10% spread adjustment plus 0.95%. We pay a commitment fee for the unused portion of the Credit Facility. This fee is either 0.10% or 0.125% per annum based on our use of the Credit Facility.

**Senior Unsecured Promissory Notes Payable** 

We have issued senior unsecured promissory notes under our master note agreement (the Master Note Agreement) in the aggregate principal amount of $125.0 as of December 31, 2025. Our aggregate borrowing capacity under the Master Note Agreement is $900.0; however, none of the institutional investors party to that agreement are committed to purchase notes thereunder. There is no amortization of these notes prior to their maturity date and interest is payable quarterly. The notes currently issued under our Master Note Agreement, including the maturity date and fixed interest rate per annum of each series of note, are contained in the table above. The Master Note Agreement contains certain financial and other covenants and we are currently in compliance with these covenants.

**Note 10. Segment Reporting** 

Each of our geographic regions (U.S., Canada, Mexico, Central & South America, Europe, Asia, and SE Asia) are engaged in business activities for which they may earn sales and incur expenses. Discrete financial information is available at the geographic region level through our internal Return on Asset (ROA) reporting. The ROA reporting is ultimately a selling location income statement with an ROA calculation and the results are compiled by geographic region. ROA pre-tax profit measures financial performance and drives compensation programs.

Our Chief Operating Decision Maker (CODM) is a group consisting of our Chief Executive Officer and President/Chief Sales Officer. We consider each geographic region to be an operating segment. The CODM regularly reviews ROA pre-tax profit to make decisions about the allocation of resources at the geographic region level. Operating segment significant expense categories and amounts are not regularly reviewed by or provided to our CODM. Segment expenses represent the difference between net sales and ROA pre-tax profit and consist of cost of sales and SG&A expenses. However, our CODM reviews consolidated expense information to manage the operations of the business.

Considering our operating segments outside of the U.S. individually represent less than 10% of our total operating segment net sales, ROA pre-tax profit, and ROA assets, we do not consider them reportable segments. Therefore, we report the results of our one reportable segment (U.S.) below. Further details on our significant accounting policies can be found in Note 1, which are applied company wide.

Our segment measure of profit or loss is ROA pre-tax profit and our measure of assets is ROA assets. ROA pre-tax profit is not a financial measure calculated in accordance with GAAP and excludes inter-company transactions.

The following table presents a reconciliation of reportable segment net sales from external customers to consolidated net sales for the periods ended December 31:

---

| | | | |
|:---|:---|:---|:---|
| | **2025** | 2024 | 2023 |

<sup>(2)&nbsp;&nbsp;&nbsp;&nbsp;</sup>Other reconciling items includes depreciation and amortization expense for certain assets not allocated to the ROA and differences in allocations specific to the ROA that drive decisions in the field and compensation programs.

**Note 11. Legal Contingencies**

We are involved in certain legal actions, including those that are ordinary routine litigation incidental to our business. The outcomes of these legal actions are not within our complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages, as well as other relief, that could require significant expenditures or result in lost sales. We record a liability for these legal actions when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded. As of December 31, 2025, there were no litigation matters that we consider to be probable or reasonably possible to have a material adverse impact on our consolidated financial statements.

**Note 12. Subsequent Events**

We evaluated all subsequent event activity and concluded that no subsequent events have occurred that would require recognition in the consolidated financial statements or disclosure in the Notes to Consolidated Financial Statements, with the exception of the dividend declaration and stock option activities disclosed in Note 5.

**ITEM 9A. CONTROLS AND PROCEDURES**

**Disclosure Controls and Procedures**

As of the end of the period covered by this report, we conducted an evaluation, under the supervision and with the participation of our principal executive officer and principal financial officer, of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Securities Exchange Act)). Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures are effective as of December 31, 2025. Our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow for timely decisions regarding required disclosure.

**Management's Annual Report on Internal Control Over Financial Reporting**

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)provide reasonable assurance that the transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2025 based on the framework in *Internal Control – Integrated Framework* (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our assessment and those criteria, our management has concluded that we maintained effective internal control over financial reporting as of December 31, 2025.

The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

**Changes in Internal Control Over Financial Reporting**

There have been no changes in internal control over financial reporting during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

## Exhibit 4.1

**Exhibit 4.1**

**DESCRIPTION OF CAPITAL STOCK**

The summary of the general terms and provisions of the capital stock of Fastenal Company (the "<u>Company"</u>) set forth below does not purport to be complete and is subject to and qualified by reference to the Company's Restated Articles of Incorporation, as amended (the "<u>Articles"</u>) and Restated By-Laws ("<u>By-Laws</u>," and together with the Articles, the "<u>Charter Documents"</u>), each of which is incorporated herein by reference and attached as an exhibit to the Company's most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission. For additional information, please read the Company's Charter Documents and the applicable provisions of the Minnesota Business Corporation Act (the "<u>MBCA"</u>).

**Capital Stock**

The Company is authorized to issue up to 1,605,000,000 shares, of which 5,000,000 have been designated preferred stock, par value of $0.01 per share ("<u>Preferred Stock"</u>) and 1,600,000,000 have been designated common stock, par value $0.01 per share ("<u>Common Stock"</u>).

***Voting Rights***

The holders of shares of Common Stock are entitled to one vote for each share held of record on all matters submitted to a vote of shareholders, including the election of directors. The Articles do not permit cumulative voting in the election of directors. Subject to the rights, if any, of the holders of one or more classes or series of Preferred Stock issued by the Company, each director of the Company shall be elected at a meeting of shareholders by the vote of the majority of votes cast with respect to that director, provided that directors of the Company shall be elected by a plurality of the votes present and entitled to vote on the election of directors at any such meeting for which the number of nominees (other than nominees withdrawn on or prior to the day preceding the date the Company first mails its notice for such meeting to the shareholders) exceeds the number of directors to be elected.

***Dividend Rights***

Subject to any prior rights of any Preferred Stock then outstanding, the holders of shares of Common Stock are entitled to receive ratably such dividends as may be declared by the Company's board of directors out of funds legally available therefor.

***Liquidation Rights*** 

Upon any liquidation or dissolution of the Company, the holders of shares of Common Stock share ratably, in proportion to the number of shares held, in the assets available for distribution after payment of all prior claims, including all prior claims of any Preferred Stock then outstanding.

***No Preemptive Rights***

Shareholders of the Company shall have no preemptive rights to acquire securities or rights to purchase securities of the Company.

***Listing*** 

The Company's Common Stock is currently traded on the Nasdaq Stock Market LLC under the symbol "FAST."

**Anti-Takeover Provisions**

The Charter Documents and the MBCA contain certain provisions that may discourage an unsolicited takeover of the Company or make an unsolicited takeover of the Company more difficult. The following are some of the more significant anti-takeover provisions that are applicable to the Company:

***Special Meetings of Shareholders; Shareholder Action by Unanimous Written Consent; and Advance Notice of Shareholder Business Proposals and Nominations***

Section 302A.433 of the MBCA provides that special meetings of the Company's shareholders may be called by the Company's chief executive officer, chief financial officer, two or more directors, or shareholders holding 10% or more of the voting power of all shares entitled to vote, except that a special meeting demanded by shareholders for the purpose of considering any action to directly or indirectly facilitate or effect a business combination, including any action to change or otherwise affect the composition of the board of directors for that purpose, must be called by 25% or more of the voting power of all shares entitled to vote. Section 302A.441 of the MBCA also provides that action may be taken by shareholders without a meeting only by unanimous written consent. The By-Laws provide an advance written notice procedure with respect to shareholder proposals of business and shareholder nominations of candidates for election as directors. Shareholders at an annual meeting are able to consider only the proposals and nominations specified in the notice of meeting or otherwise brought before the meeting by or at the direction of the board of directors or by a shareholder that has delivered timely written notice in proper form to the Company's general counsel of the business to be brought before the meeting.

------

**Exhibit 4.1 (Continued)**

***Control Share Provision***

Section 302A.671 of the MBCA applies, with certain exceptions, to any acquisition of the Company's Voting Stock (from a person other than the Company and other than in connection with certain mergers and exchanges to which the Company is a party) resulting in the acquiring person owning 20% or more of the Company's Voting Stock then outstanding. Section 302A.671 requires approval of any such acquisitions by both (i) the affirmative vote of the holders of a majority of the shares entitled to vote, including shares held by the acquiring person, and (ii) the affirmative vote of the holders of a majority of the shares entitled to vote, excluding all interested shares. In general, shares acquired in the absence of such approval are denied voting rights and are redeemable at their then fair market value by the Company within 30 days after the acquiring person has failed to give a timely information statement to the Company or the date the shareholders voted not to grant voting rights to the acquiring person's shares. The control share provision applies to any corporation that has not expressly provided to the contrary in its articles or in its bylaws approved by its shareholders. The Articles provide that this provision shall apply.

***Business Combination Provision***

Section 302A.673 of the MBCA generally prohibits the Company or any of its subsidiaries from entering into any merger, share exchange, sale of material assets or similar transaction with a 10% shareholder within four years following the date the person became a 10% shareholder, unless either the transaction or the person's acquisition of shares is approved prior to the person becoming a 10% shareholder by a committee of all of the disinterested members of the board of directors. The business combination provision applies to any corporation that has not expressly provided to the contrary in its articles or its bylaws. The Articles provide that this provision shall apply.

***Takeover Offer; Fair Price***

Under Section 302A.675 of the MBCA, an offeror may not acquire shares of a publicly held corporation within two years following the last purchase of shares pursuant to a takeover offer with respect to that class, including acquisitions made by purchase, exchange, merger, consolidation, partial or complete liquidation, redemption, reverse stock split, recapitalization, reorganization, or any other similar transaction, unless (i) the acquisition is approved by a committee of the board's disinterested directors before the purchase of any shares by the offeror pursuant to the earlier takeover offer, or (ii) shareholders are afforded, at the time of the proposed acquisition, a reasonable opportunity to dispose of the shares to the offeror upon substantially equivalent terms as those provided in the earlier takeover offer.

***Greenmail Restrictions*** 

Under Section 302A.553 of the MBCA, a corporation is prohibited from buying shares at an above-market price from a greater than 5% shareholder who has held the shares for less than two years unless (i) the purchase is approved by holders of a majority of the outstanding shares entitled to vote or (ii) the corporation makes an equal or better offer to all shareholders for all other shares of that class or series and any other class or series into which they may be converted.

***Authority of the Board of Directors***

## Exhibit 10.1

**Exhibit 10.1**

**Fastenal Company**

**Bonus Program for Executive Officers**

***Quarterly Incentives***

Our executive officers are eligible for cash incentives through individual bonus arrangements based on improvements in the overall financial performance of Fastenal and/or their respective areas of responsibility. The bonus arrangements provide our executive officers with the opportunity to earn a cash bonus for each quarter during a year when we increase our income above a predetermined minimum target.

The primary cash bonuses for all of our named executive officers are based on Fastenal's growth in pre-tax income and/or the officer's area of responsibility. The compensation committee selected pre-tax income as the appropriate metric for calculating cash bonuses for those officers because of the committee's belief that the focus of the named executive officers should be on profitability, which is the primary driver of shareholder value. The cash bonus for our chief financial officer also includes a component based on growth in company-wide net income because the responsibilities of the position allow for the affect of our entire financial position, including our tax position. The compensation committee believes that no named executive officer should earn a cash bonus under this program for a quarter unless financial performance has improved and therefore sets minimum targets for each quarter that are equal to the income achieved for the same quarter in the prior year. The compensation committee requires growth in income before any bonuses can be earned due to its belief that growth is achievable with superior effort and will generate the cash necessary to expand Fastenal's operations in accordance with our business plans and increase shareholder value.

The payout percentage used to calculate the amount of each named executive officer's primary quarterly cash bonus reflects the officer's track record in his or her current position (i.e., newly promoted executives historically have had to prove themselves in their new positions before earning higher payout percentages) and relative ability to impact profitability.

Cash bonus payments to our named executive officers are tied directly to our financial performance so that they increase only if and to the extent Fastenal's profitability grows; therefore, we do not believe it is necessary for payouts under our primary executive cash incentive program to be capped. We believe the current design of our executive bonus arrangements, along with our other controls, adequately mitigates risk and the use of multiple metrics would not be in furtherance of our goal of keeping our compensation programs simple, understandable, and transparent, and would risk keeping our executives focused on things other than profitability, thereby depriving them of the clear feedback and motivation necessary to improve our bottom line. Therefore, we do not base these cash incentives on multiple metrics.

Our named executive officers are each eligible for a supplemental bonus program. The supplemental bonus program, known as the ROA (Return on Assets) Plan, is intended to encourage better management of accounts receivable, inventory, and vehicles and provides cash incentive amounts on a quarterly basis for asset management improvement over the same quarter in the prior fiscal year and is described in more detail below.

**Exhibit 10.1 (Continued)**

2025 *Incentive Program*

The bonus arrangements for our named executive officers for 2025 were approved by our compensation committee at its last meeting in 2024, with the exception of Mr. Tunnicliff, who was appointed senior executive vice president and chief financial officer effective November 10, 2025. Consistent with prior years, the bonuses for 2025 were based on Fastenal's growth in pre-tax income or net income and/or the officer's area of responsibility. The bonuses for each quarter were determined by applying a payout percentage to the amount by which pre-tax income or net income exceeded 100% of pre-tax income or net income for the same quarter in 2024. The compensation committee determined that the payout percentages for each of the named executive officers for 2025 would remain unchanged from those in effect at the end of 2024. Ms. Lisowski's bonus payout percentages were increased temporarily effective April 17, 2025, in connection with her appointment as interim chief financial officer, in addition to executive vice president - chief accounting officer and treasurer. Mr. Tunnicliff's bonus payout percentages were determined by the compensation committee upon his appointment effective November 10, 2025.

The specific bonus opportunities for our named executive officers are summarized in the table below. Each named executive officer's cash bonus for each quarter during 2025 was determined by applying the payout percentage listed opposite his or her name below to the amount by which Fastenal's pre-tax income or net income and/or the officer's area of responsibility for that quarter exceeded 100% of such income in the same quarter of 2024 (the 'minimum target').&nbsp;&nbsp;&nbsp;&nbsp;

---

| | | |
|:---|:---|:---|
| **Name** | **Income Type** | **Payout Percentage** |
| Mr. Florness | Company-wide pre-tax income | 1.75% |
| Mr. Tunnicliff | Company-wide pre-tax income / Company-wide net income | 0.50% / 0.35% |
| Ms. Lisowski <sup>(1)</sup> | Company-wide pre-tax income / Company-wide net income | 0.40% / 0.27% |
| Mr. Watts | Company-wide pre-tax income | 1.25% |
| Mr. Miller <sup>(2)</sup> | Pre-tax income / Company-wide pre-tax income | 0.75% / 0.15% |
| Mr. Soderberg | Company-wide pre-tax income | 0.65% |
| Mr. Lewis <sup>(3)</sup> | Company-wide pre-tax income / Company-wide net income | 0.50% / 0.35% |

---

(1)Ms. Lisowski's bonus percentages were 0.33% / 0.23% from January 1, 2025 to April 16, 2025. Ms. Lisowski's bonus percentages changed temporarily to 0.40% / 0.27% effective April 17, 2025 when she assumed the role of interim chief financial officer.

(2)The approximate percentage of pre-tax income attributable to our operations in the geographic area under Mr. Miller's leadership was approximately 86%.

(3)Mr. Lewis resigned effective April 16, 2025.

The following table sets out, for each quarter in 2025, our actual and minimum target pre-tax income and net income on a company-wide basis for that quarter, in each case rounded to the nearest thousand. (As indicated above, the 'minimum target' amount in 2024 was 100% of such income in the same quarter of 2024.)

---

| | | | | |
|:---|:---|:---|:---|:---|
| **2025** | **Actual<br>Pre-tax Income** | **Minimum Target<br>Pre-tax Income** | **Actual<br>Net Income** | **Minimum Target<br>Net Income** |
| First quarter | $393141000 | $389844000 | $298656000 | $297740000 |
| Second quarter | 436610000 | 386364000 | 330283000 | 292682000 |
| Third quarter | 440610000 | 387627000 | 335453000 | 298041000 |
| Fourth quarter | 384590000 | 344293000 | 294067000 | 262090000 |

---

As noted above, the ROA Plan, which is designed to encourage careful management of assets, namely accounts receivable, inventories, and pick-up trucks, for 2025 was approved by the compensation committee for our named executive officers. Quarterly bonuses would be payable pursuant to the ROA Plan if a specified level of improvement in asset management relative to the comparable prior year quarter was achieved. Improvement in asset management was assessed using a two-quarter average of total assets divided by the trailing 12-month net sales, which we refer to as the 'performance percentage.' If the performance percentage when compared to the prior year benchmark showed improvement at a level specified in the table below, the named executive officers would receive the corresponding bonus amount.

|:---|:---|
| **Improvement Amount Exceeded** | **Bonus Payout** |
| 150 basis points | $15000 |
| 100 basis points (but less than 150 basis points) | $10000 |
| 50 basis points (but less than 100 basis points) | $5000 |

---

In addition, for each whole percentage improvement (*e.g.*, 41.0%, 40.0%, 39.0%, etc.) a $10,000 bonus would be payable for the quarter when the new whole percentage threshold was first achieved. We achieved improvement and paid bonus amounts to our named executive officers, pursuant to the ROA Plan for each quarter in fiscal 2025 as follows:

*2026 Incentive Program*

The bonus arrangements for our named executive officers for 2026 were approved by our compensation committee at its last meeting in 2025. The bonus plans for our named executive officers for 2026 are unchanged from our 2025 bonus plans, except that Mr. Miller's quarterly bonus increased and will be applied to Company-wide quarterly pretax earnings exceeding 100% of the same quarter in the previous year to reflect his increased responsibilities, which include oversight of Company sales leadership.
