Sales growth reaches core markets

Fastenal's net sales rose to 2.4633 billion US dollars in the quarter ended September 30, 2026, from 2.1333 billion US dollars a year earlier. The company said both periods contained 64 business days, making the comparison directly comparable. Daily sales reached 38.5 million US dollars, up from 33.3 million US dollars.

Management attributed the increase to customer contract signings, product pricing and a modest improvement in industrial production. Manufacturing remained the largest end market, accounting for 76.6 percent of sales. Heavy manufacturing daily sales increased 20.2 percent, while non-residential construction grew for the sixth consecutive quarter.

Contract customers continued to outperform non-contract customers. Their daily sales increased 18.8 percent and represented 76.5 percent of quarterly revenue, compared with 73.8 percent a year earlier. Fastenal's larger customer sites also expanded: locations generating at least 50,000 US dollars in monthly sales increased to 3,288 from 2,771.

Operating leverage supports earnings

Gross margin narrowed to 44.8 percent from 45.3 percent as the customer mix shifted toward larger accounts. Fastenal said those relationships typically carry lower gross margins but generate higher absolute profit dollars and support fixed-cost leverage.

That operating leverage lifted operating margin to 21.5 percent from 20.7 percent. Net income rose 19.7 percent to 401.6 million US dollars, while diluted earnings per share increased to 0.35 US dollars from 0.29 US dollars. Operating cash flow reached 421.6 million US dollars, equal to 105 percent of net income.

Digital investment remains central

Fastenal signed 7,484 weighted FASTBin and FASTVend devices during the quarter. The company lowered its 2026 signing goal to between 27,000 and 29,000 machine-equivalent units from a previous range of 28,000 to 30,000.

Digital activity nevertheless continued to expand. Sales through Fastenal's managed inventory technology rose 14.6 percent to 1.1213 billion US dollars, while Digital Footprint sales increased 16.1 percent to 1.5365 billion US dollars in the quarter. For 2026, the company expects capital spending of between 310 million and 330 million US dollars, including investments in facilities, information technology and trucking.

Fastenal's results point to a business that is gaining share with larger customers while using scale to protect operating profitability. The lower gross margin and revised device-signing target remain important counterweights for investors assessing how much of the recent growth can continue.
