Fastenal Company Reports 2026 Third Quarter Earnings

•Daily sales increased 15.5% year-over-year, primarily driven by share gains with larger customers, pricing actions, and broad-based demand across core end markets.

•Operating margin was 21.5%, a 90 basis point improvement year-over-year, as selling, general, and administrative expense leverage more than offset customer mix-related gross margin pressure.

•Operating cash flow was $422 million, representing 105% of net income, reflecting the timing of working capital changes associated with strong sales growth.

•Returned $328 million to shareholders through dividends and share repurchases, representing 82% of net income.

•Continued progress on strategic initiatives, including increased sales effectiveness through key account wins, expansion of digital technologies, and deeper penetration through new customer site growth.

QUARTERLY RESULTS OF OPERATIONS

Sales

Net sales increased $330.0, or 15.5%, in the third quarter of 2026 when compared to the third quarter of 2025 (both periods had the same number of business days). Sales performance reflects the contribution from improved customer contract signings since the first quarter of 2024, product pricing, and a modest improvement in industrial production in the first nine months of 2026. Foreign exchange rates negatively impacted sales growth by approximately 10 basis points in the third quarter of 2026 as compared to the third quarter of 2025 when foreign exchange rates contributed approximately 10 basis points to sales growth. The impact of product pricing on net sales in the third quarter of 2026 was an increase of approximately 240 basis points, compared to an increase of 240 to 270 basis points in the third quarter of 2025.

From a product portfolio standpoint, we classify our offerings into four primary categories: fasteners, safety supplies, cutting tools, and other product lines. 'Other product lines' encompasses seven smaller product segments, including tools and janitorial supplies.

1

Beginning in the fourth quarter of 2025, we expanded our reporting to provide a more comprehensive view of direct (original equipment manufacturing/production) and indirect (maintenance, repair, and operations/facilities maintenance) business across product categories. Direct materials generally include products incorporated into finished goods or that directly support customers' production processes, while indirect materials support customers' facility operations, maintenance, and safety needs. During the third quarter of 2026, direct materials outpaced indirect materials, reflecting greater contribution from fastener sales and continued strength with manufacturing customers.

The DSR change when compared to the same period in the prior year and the percent of sales in the period were as follows:
