Fastenal Company reported higher sales and profits in the fourth quarter and full year of 2025, as growth among contract customers, manufacturing accounts and digital inventory programs offset sluggish industrial production.
The Winona, Minnesota-based distributor of industrial and construction supplies, said full-year sales rose 8.7% to $8.20 billion, up from $7.55 billion in 2024. Net income increased 9.4% to $1.26 billion, compared with $1.15 billion a year earlier.
In the fourth quarter, Fastenal reported sales of $2.03 billion, an 11.1% increase from $1.82 billion a year earlier. Quarterly net income rose 12.2% to $294.1 million, up from $262.1 million in the prior-year period.
Fastenal said higher unit volumes, pricing and continued momentum from customer contract signings that began accelerating in early 2024 supported results. Daily sales increased 9.1% for the year and 11.1% in the fourth quarter, with pricing contributing 310 to 340 basis points to fourth-quarter sales growth.
New customer-site data highlights mix shift.
Fastenal said 2025 marked a change in its performance disclosures, adding more detailed reporting on customer sites, spend levels and sales per site to supplement traditional measures such as branch expansion and onsite signings.
During the fourth quarter, Fastenal served an average of 92,136 customer sites, down from 100,435 a year earlier, but generated higher revenue per site as larger customers expanded spending. The number of customers spending $10,000 or more per month rose to 11,712, up from 10,837 a year earlier. Sites spending $50,000 or more per month increased to 2,657, compared with 2,330.
Manufacturing customers continued to drive results. In the fourth quarter, manufacturing sites generated $1.52 billion in sales, up from $1.37 billion a year earlier, while average monthly sales per manufacturing site rose to $12,511, compared with $10,695 in the prior-year quarter.
Non-manufacturing customer sites produced $503.9 million in fourth-quarter sales, up from $457.8 million a year earlier, with growth led by transportation, warehousing, and data center customers. Sales to smaller, non-contract customers remained weaker.
Fastenal said manufacturing and contract customers outperformed other segments, reflecting strength among large, multi-site accounts using managed-spend programs, onsite locations, and automated inventory systems. Contract customers accounted for three quarters of fourth-quarter sales, with growth outpacing non-contract customers.
The company also reported continued expansion of its Fastenal Managed Inventory (FMI) offerings, including FASTStock, FASTBin and FASTVend. Fastenal signed 5,966 weighted FASTBin and FASTVend devices in the fourth quarter, bringing full-year signings to 25,892 machine-equivalent units, in line with its 2025 target. The company said it aims for 28,000 to 30,000 weighted signings in 2026.
Sales flowing through FMI technology totaled $3.71 billion for the year, up from $3.25 billion in 2024, reflecting both new installations and the shift of product volume from traditional stocking locations to digital systems.
Fastenal operates in more than 3,000 locations and serves customers across manufacturing, construction, transportation, government, and other industrial end markets in North America and internationally.
