## How the company works

What it sells, how it makes money, and the anatomy of the extremes: what has to break for the result to land far from the forecast, either way. In Fastenal's own words, from its annual report for 2025.

Fastenal supplies factories and job sites with the fasteners, safety gear, tools and consumables they use every day, from branches and from bins and vending machines inside the customer's own plant.

#### How it makes money

Distribution at the point of use. Net sales were $8,200.5M in 2025, up 8.7%, at a gross margin of 45.0%, with operating income of $1,655.7M, 20.2% of sales, and net income of $1,258.4M. 75.9% of sales are to manufacturers; fasteners are 30.5% of sales and safety supplies 22.2%. The customer buys through a Fastenal person at a local branch or at a Site inside its own operations, and increasingly through Fastenal Managed Inventory, the FASTStock, FASTBin and FASTVend devices that refill themselves: FMI sales were $3,712.7M, 44.7% of the total, and the Digital Footprint 61.4% of sales.

#### What it sells

| 2025 | Share of sales | A year earlier |
| --- | --- | --- |
| Fasteners threaded fasteners and miscellaneous supplies, standard and to customer specification | 30.5% | 30.7% |
| Safety supplies gloves, eyewear, protective equipment, the Body Guard private label | 22.2% | 22.2% |
| Janitorial supplies | 9.0% | 8.8% |
| Tools | 8.3% | 8.4% |
| Hydraulics & pneumatics | 6.9% | 6.7% |
| Other lines material handling, cutting tools, electrical, welding and other | 23.1% | 23.2% |

Sales by product line as Fastenal reports them. By end market: manufacturing 75.9%, non-residential construction 8.1%, other 16.0%. National accounts are 65% of sales.

#### Unit economics

A fixed network, 1,595 branches in 25 countries and 15 distribution centers, sold against a growing number of large customer Sites: the company's strategy "prioritizes customer sites with monthly sales potential of $50,000 or more", and those Sites, 2,653 of them, produced $4,326M of sales. Each FMI device adds transactions without a salesperson's visit, and each Site adds sales to a branch already paid for, so selling expense falls as a share of sales: 24.8% in 2025 against 25.1%. 24,489 employees. About 96% of what it sells is made by others; private label brands are about 11% of sales.

#### Competitive position

The company says its 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" in the small markets where it has branches, competing on "customer service, price, convenience, product availability, and cost saving solutions". Its edge is a trained person at each location and inventory inside the customer's plant, which it believes "is difficult for large and small competitors to replicate" and sets it apart from web purchasing.

#### Biggest cost inputs

Product bought from manufacturers, much of it imported and so exposed to tariffs, which the company may not be able to pass through in price; payroll at branches, Sites and distribution centers, the largest operating cost, with incentive pay that rises with profit; occupancy; freight and fuel; and the FMI devices themselves.

#### Anatomy of a large **upside**

- **Large Sites and FMI keep taking share inside the plant.** Sites of $50,000 a month or more grew from 2,364 to 2,653 and their sales from $3,754M to $4,326M; FMI sales rose 14.6%. Each win pulls a customer's whole bill of indirect and direct materials through one supplier.
- **Manufacturing turns up.** Three quarters of sales go to manufacturers and the company says market conditions were "sluggish" in 2025; daily sales to manufacturing customers still grew 10.4%, and an industrial upcycle, reshoring included, lifts the same network with little added cost.
- **Operating leverage.** Selling expense fell to 24.8% of sales from 25.1% and operating income rose 9.6% on 8.7% sales growth; as growth comes through existing branches and devices, more of each sales dollar reaches profit.

#### Anatomy of a large **downside**

- **An industrial downturn.** The business "has historically been" tied to manufacturing activity; a slump in production, construction or commodity industries cuts volume through a network whose costs are fixed.
- **Tariffs and mix squeeze the gross margin.** An "inability to capture price increases in response to increased costs associated with tariffs" and the shift toward non-fastener products, contract accounts and Onsite customers, which carry lower gross margins, have "caused our gross profit percentage to decline".
- **The large distributors and the web close the gap.** National distributors with scale, and purchasing over the internet, replicate the bins, vending and digital tools; the premium for a person at each location erodes.

Written from Fastenal's annual report for 2025, in its words and numbers. The extremes are the long view, what has to break for the result to land far from the forecast; the quarter's own cases, each model's, are on the quarter forecast.
