Fastenal Q3 Earnings Call Highlights

Key Points

• Fastenal delivered strong Q3 growth: Sales rose 15.5% to $2.46 billion, while operating income and EPS increased about 20%. Operating margin expanded 90 basis points to 21.5%, supported by market-share gains and SG&A leverage.
• Large accounts and technology-enabled services drove momentum: Sales from customer sites spending at least $50,000 monthly increased about 28%, while contract customers generated more than 76% of sales. Digital sales grew roughly 16%, and the FASTBin installed base surpassed 143,000 units.
• Management expects continued productivity gains but less pricing support: Pricing contributed 2.4 percentage points to growth and is expected to become a smaller tailwind. Fastenal maintained its $310 million–$330 million capital-spending outlook and returned $328 million to shareholders during the quarter.

Fastenal NASDAQ: FAST reported third-quarter 2026 sales growth of 15.5% and operating-margin expansion, as the industrial distributor cited market-share gains with larger customers, new contract wins and increased use of technology-enabled supply-chain services.

Net sales reached $2.46 billion, an increase of $330 million from a year earlier. Operating income increased $90 million year over year, which President and CEO Jeff Watts said was the largest single-quarter year-over-year increase in the company’s history. Operating margin rose 90 basis points to 21.5%, while operating earnings and earnings per share each grew by roughly 20%.

Fastenal’s trailing 12-month return on invested capital increased 230 basis points to 32.5%, compared with a 10-year average of about 28%, according to Chief Financial Officer Max Tunniclff.

Large accounts and contracts drive sales

Watts said the quarter’s results reflected accelerated growth, improved conversion of sales into profit, and market-share gains tied to the company’s key-account strategy. Fastenal’s contract count increased 6.4% from the prior year, with new signings weighted toward multi-site national accounts.

The number of customer sites spending at least $50,000 per month rose nearly 19%, to roughly 3,300 from approximately 2,800 a year earlier. Sales from those sites increased about 28%. Contract customers represented more than 76% of sales, and their daily sales increased 18.8%.

Pricing contributed approximately 2.4 percentage points to third-quarter growth, a slower contribution than earlier in the year as the company began lapping stronger pricing actions from 2025. Watts said industrial market conditions improved during the first half and continued to improve in the third quarter, though Fastenal’s growth exceeded the markets it serves.

Tunniclff said daily sales growth improved to 15.5% from 14.7% in the second quarter. Heavy manufacturing, which represented about 45% of sales, posted approximately 20% daily sales growth. Growth was particularly strong in key accounts, machined products, aerospace and industrial equipment. Other manufacturing grew about 13%.

Direct-material sales increased approximately 19%, outpacing roughly 14% growth in indirect materials. Electrical, tools and other industrial products also grew faster than the company overall.

Management said data centers were a meaningful contributor to sales growth. Watts estimated that data-center-related activity accounted for roughly 4 to 5 percentage points of growth, though he said it was difficult to precisely measure because the company serves the market through a range of existing customer relationships, including construction contractors and manufacturers.

Digital and supply-chain services expand

Digital sales accounted for 61.4% of total sales and grew approximately 16% on a daily basis. Fastenal signed about 7,500 weighted FMI, or Fastenal Managed Inventory, devices during the quarter, equivalent to about 117 per day, compared with 110 per day a year earlier.

The company’s installed base exceeded 143,000 units, up 7% year over year, and sales through FASTBin increased approximately 18%. Fastenal continues to expect 27,000 to 29,000 weighted device signings for the full year.

Watts described an example of a new customer that had experienced direct-material stock-outs, supply-chain shortages and limited visibility into product consumption. Fastenal reorganized storage areas, deployed bar-coded bins and FMI technology, created planograms and connected the customer to its FAST360° system. The company said the project increased digital visibility from zero to 99%, eliminated stock-outs and reduced inventory, with expected long-term overall cost savings of 25% to 30%.

Margins benefit from SG&A leverage

Third-quarter gross margin was approximately 45%, down 40 basis points from a year earlier but up 20 basis points sequentially. Customer mix was the primary year-over-year headwind, reducing gross margin by approximately 50 basis points as larger customers generally carry lower gross margins despite supporting attractive operating margins through volume and service efficiency.

Price-cost dynamics created an approximately 30-basis-point headwind, though that was 10 basis points better than in the second quarter. Favorable items added about 40 basis points to gross margin, including direct-sourcing savings, supplier rebates and tariff refunds. Tunniclff said roughly half of that benefit reflected timing and should not be assumed to continue in the underlying run rate.

SG&A leverage more than offset the gross-margin decline. SG&A expenses benefited from 130 basis points of leverage, including a 90-basis-point improvement in employee costs as a percentage of sales and roughly 50 basis points of occupancy-cost improvement. Full-time-equivalent headcount increased less than 1%.

Management said lower headcount growth did not reflect planned cuts. Instead, Watts and Tunniclff attributed the productivity gains to automation, artificial intelligence, role specialization and tools that reduce manual work. Watts said a process that previously could require five or six days of sourcing and quoting can now take about 15 minutes using newer technology tools.

During the call, management also discussed a small acquisition related to AI and technology orchestration. Tunniclff said the transaction was not material enough to require disclosure, while Watts said the acquired company would help Fastenal advance its technology capabilities.

Cash flow and capital allocation

Operating cash flow totaled approximately $422 million, or 105% of net income, while free cash flow was about $350 million, or 87% of net income. Receivables rose with sales growth, particularly among larger customers with longer payment terms. Inventory increased approximately 3% over the past year while product availability remained high.

Third-quarter capital spending was about $72 million, or 2.9% of sales, focused on hub and facility capacity, automation, FMI equipment, information technology and transportation assets. Fastenal maintained its full-year expectation for net capital spending of $310 million to $330 million.

The company returned $328 million to shareholders during the quarter, including $298 million in dividends and $30 million in share repurchases. Management said Fastenal returned approximately $1.2 billion over the trailing 12 months after funding operating and capital needs.

Looking ahead, Tunniclff said Fastenal expects pricing to become less of a growth tailwind, but management continues to focus on gaining share and improving price-cost performance. The company said it sees continued structural opportunities to improve productivity while investing to support growth.
