Fastenal Company Q3 2026 Net Income Rises 19.7% as Sales and Operating Leverage Expand

Fastenal Company (NASDAQ:FAST) reported third-quarter net income of $401.6 million, up 19.7% from the same period last year. Diluted earnings per share rose to $0.35 from $0.29. Net sales increased 15.5% to add $330.0 million compared to the third quarter of 2025, supported by gains in customer contracts signed since early 2024, product pricing, and modest growth in industrial production.

Operating expense leverage drove profitability higher, with selling, general, and administrative expenses improving 130 basis points to 23.3% of sales. This helped raise operating income margin to 21.5% from 20.7% a year ago. Gross margin dropped 40 basis points year over year to 44.8%, largely due to a customer mix shift toward larger accounts that carry lower gross margins but higher dollar profits. However, gross margin improved sequentially from 44.6% in the second quarter.

Investors should monitor the expansion of digital inventory devices and contract sign-ups. Fastenal Company signed 7,484 weighted device units in the quarter and adjusted its full-year 2026 signing goal to between 27,000 and 29,000 units, down slightly from its prior target of 28,000 to 30,000 units. Operating cash flow reached $421.6 million for the quarter, up 9.0%, as working capital needs expanded to support double-digit sales growth.
