Fastenal Company FAST

Key data

The business

Fastenal is the biggest industrial distributor in the country you have never thought about. It sells the unglamorous consumables a factory burns through every day: threaded fasteners, cutting tools, gloves, safety glasses, cleaning supplies, the parts nobody notices until the line stops for want of them. Manufacturing is 76% of revenue, non-residential construction 8%, everything else 16%, and about 96% of sales are inside the United States. The moat is physical proximity. Over the last decade Fastenal stopped being a chain of local stores and became a supplier that lives inside the customer's own building, through Onsite locations, staffed stockrooms on the factory floor, and industrial vending machines that dispense parts and reorder automatically. Once a vending machine is bolted to a customer's wall and wired to Fastenal's replenishment, switching suppliers means ripping out the plumbing of your own shop floor. That embedded hardware is why a distributor with no patents and thin gross margins earns 34% on equity.

The numbers

Two things are happening at once: the top line has reaccelerated, and the profit on each dollar of parts is quietly eroding.

Revenue growth ran near 8% a year from 2021 through 2025, then stepped up: Q2 2026 sales of $2.39B were 14.7% above a year earlier, the fastest in the visible window and the largest quarter Fastenal has ever reported, with net income up 15.9%. Yet the company did not beat expectations to get there. Its last four quarters each landed within a penny of consensus, $0.33 against $0.33 this time. This is a metronome, not a surprise machine, so the climb to a twelve-year-high multiple is the market paying up for reliability, not reacting to a blowout.

The EPS drop from $1.89 to $1.01 in 2023 is a 2-for-1 split, not a collapse in earnings; net income kept rising. Compound the five years and revenue grew about 8% annually and net income about 8%, the double-digit-adjacent rate of a share-gaining distributor in a flat industrial economy. The recent step to mid-teens is the tell that matters: if it is device-driven share capture it persists, if it is restocking it fades. Twelve analysts put FY27 earnings at $1.40, roughly 15% above this year, betting on the former.

The gross-margin give-back that looked worth watching a month ago held rather than reversed: gross margin slipped to 44.6% in Q2 from 45.3% a year earlier, the 50 basis points management attributes to the shift toward larger, lower-margin accounts. What saves the model is fixed-cost leverage.

Operating margin sat at 21.0%, flat with a year ago, because bigger customers push more volume through the same branches and trucks. That is the whole industrials case in two rows: let gross margin fall if operating margin holds, because absolute profit dollars are what compound.

Management

Insiders are net sellers, modestly. Over twelve months they sold about $4.5M against $253K of buys, the largest a $1.75M sale by Reyne Wisecup in March and $1.25M by Rita Heise in August; plan status is not disclosed in the filings pulled, so read them as ordinary diversification at a $57B company, not a signal. Capital return is real and dividend-heavy: in Q2 Fastenal handed back $305.1M, 79.7% of net income, $275.4M as dividends and only $29.7M buying 650,000 shares at about $45.72, below today's price. Over five years it has returned 73% of earnings. It funds its own growth on roughly 3% of sales in capex and ships the rest out the door, which is what a 34% return on equity and 29% return on invested capital allow.

How it fails or surprises you

The cycle turns (downside). Manufacturing is 76% of revenue, and daily sales track the industrial economy in near real time. Mid-teens growth assumes factories keep running hot. A rollover shows first in the monthly daily-sales rate Fastenal reports, and at 42 times earnings there is no cushion for a sub-5% growth quarter.

Cash lags earnings (downside). Net income rose 16% in Q2 but operating cash flow fell to $265.7M from $278.6M a year earlier as inventory built to serve larger accounts. If that working-capital drag is structural rather than timing, free cash flow keeps trailing profit, and a stock at 55 times free cash flow is richer than its P/E suggests. Watch conversion return toward one over the next two prints.

The embedded base compounds (right tail). The market prices Fastenal as a cyclical distributor. If Onsite signings and vending installs keep accelerating, each unit pulls recurring, sticky consumption that gains share regardless of the cycle, and mid-teens growth proves durable rather than borrowed. The first evidence is the device-count and Onsite-signing figures in the quarterly operational release.

Closing thoughts

The next few quarterly prints will settle whether mid-teens growth sticks or mean-reverts. The downside distribution is narrow because the balance sheet is nearly debt-free and the dividend covered many times over, so a permanent loss requires industrial demand to fall and stay down for years, which has not happened in Fastenal's history. The wider question is the price. Pay 42 times earnings, the richest in twelve years and well above the 25 times peers fetch, and you have pre-paid for several years of mid-teens growth. The fatter tail is mild disappointment: growth reverts toward its 8% norm, earnings still rise, and the stock does nothing for a couple of years while the multiple compresses back toward its own history.

The bet is still that America's factories keep buying their nuts, bolts, and safety gear from Fastenal because Fastenal is already inside the building. What breaks it is not bankruptcy, it is the price: the machine works, but you are paying a twelve-year-peak multiple for a business growing earnings in the low-to-mid teens. The one pair of numbers that tells you which way it resolves is the monthly daily-sales growth rate against the 21% operating-margin line: hold both and the premium earns out, lose either and the multiple has nowhere to go but down.
