Fastenal Q3 Sales Rise 15.5% as Operating Margin Expands

Fastenal Company (Nasdaq: FAST) reported third-quarter 2026 net sales of $2.46 billion, up 15.5% from a year earlier, as growth with large customers and new contract wins helped earnings rise faster than revenue. Operating income increased 20.2% to $530.8 million, while diluted earnings per share climbed 19.8% to $0.35.

The industrial and construction supplies distributor’s operating margin expanded 90 basis points to 21.5%. A 130-basis-point reduction in selling, general and administrative expenses as a percentage of sales more than offset pressure on gross margin, reflecting expense discipline and modest headcount growth. SG&A increased 9.4% to $573.9 million, slower than the increase in revenue.

Gross profit rose 14.4% to $1.10 billion, though gross margin declined 40 basis points to 44.8%. Fastenal attributed about 50 basis points of pressure to customer mix as larger accounts, which generally carry lower gross margins, continued to grow. Price-cost effects were an approximately 30-basis-point headwind, partly offset by about 40 basis points of benefits from direct-sourcing savings, supplier rebates and tariff refunds. Roughly 20 basis points of that benefit reflected favorable timing.

Large accounts and manufacturing lead growth

Fastenal said its growth continued to outpace its end markets, supported by its key-account strategy and new contract wins. Contract count increased 6.4% year over year, with signings weighted toward multi-site national accounts. Sales from customer sites spending at least $50,000 per month rose 27.6%, increasing their share of total revenue.

Heavy manufacturing, which represented 44.6% of sales, posted daily sales rate growth of 20.2%. Growth was supported by key accounts and demand from machined products, aerospace and industrial equipment customers. Daily sales also increased 13.2% in other manufacturing markets and 12.3% across other end markets, with construction, transportation and reseller customers contributing to the quarter.

Direct-material sales grew 18.6%, compared with 14.3% growth for indirect materials. The company linked direct-material performance to large-customer signings, improved product availability and pricing actions. Pricing contributed approximately 2.4% to quarterly growth, although Fastenal said the contribution was moderating as it began to lap the peak pricing actions implemented in 2025.

Digital footprint reaches 61.4% of sales

Sales through Fastenal’s Digital Footprint accounted for 61.4% of total revenue in the quarter. eBusiness daily sales grew 14.8%, nearly matching the company-wide rate, while eBusiness represented 28.8% of net sales.

The installed base of Fastenal Managed Inventory devices reached 143,878, with FASTBin and FASTVend sales growing faster than the overall business. Device signings averaged 117 per day in the quarter, and deployments increased sequentially.

Fastenal now estimates that its Digital Footprint will represent 62% to 63% of 2026 sales, compared with its original estimate of 66%. It continues to expect 27,000 to 29,000 FMI device signings during 2026, versus an original estimate of 28,000 to 30,000. The presentation noted that these numerical representations do not constitute management guidance.

The company highlighted FMI and digital services as central to its strategy of improving order accuracy, reducing manual work and strengthening customer retention. In one customer example, Fastenal said an FMI deployment raised the account’s digital footprint from zero to 99%, automated replenishment and produced estimated savings of about 25% as onboarding continued.

Cash flow funds investment and shareholder returns

Operating cash flow totaled $421.6 million, equal to 105.0% of quarterly net income. Non-GAAP free cash flow was $349.6 million, or 87.1% of net income, down 11.9 percentage points from the prior-year conversion rate. Capital expenditures totaled $74.0 million during the quarter.

Fastenal paid $298.2 million in dividends and repurchased $30.2 million of shares, returning a combined $328.4 million to shareholders during the quarter. Over the trailing 12 months, it returned $1.18 billion, equal to 99.8% of non-GAAP free cash flow.

Trailing-12-month non-GAAP return on invested capital increased to 32.5% from 30.2% a year earlier. The comparable GAAP return on assets rose to 26.7% from 24.9%.

Fastenal’s priorities remain gaining share through key accounts and contract wins, expanding its inventory-management and digital capabilities, and reaching additional products, geographies and business models. The company cautioned that future sales, margins, pricing, tariffs, capital spending and technology deployments remain subject to uncertainty. Nearer-term constraints disclosed in the presentation include the lower gross-margin profile of large customers, continuing price-cost pressure and Digital Footprint and FMI signing estimates that are below the company’s original 2026 assumptions.
