Fastenal, the unassuming distributor of nuts, bolts, and industrial supplies, might not be the first company that springs to mind when you think of high-growth tech disruptors. But hidden beneath the surface of their recent earnings call lies a fascinating trend, one that has the potential to reshape the company's future and dramatically amplify its market share gains.

The key? A quiet revolution in Fastenal's customer base, driven by the pandemic-era shift to e-commerce and a strategic decision to prioritize partnerships with larger, more sophisticated customers. While analysts have focused on the company's recent struggles with Onsite signings and sluggish overall growth, they've largely overlooked the implications of this subtle shift in customer mix.

Fastenal has been quietly shedding its smaller, less profitable customers, those who historically relied on walk-in retail transactions at its sprawling network of branches. This shift was already underway before the pandemic, but the forced closure of branch front doors in 2020 dramatically accelerated the trend. As Dan Florness, Fastenal's CEO, pointed out, sales to cash customers, representing purely retail transactions, have plummeted from 4% of revenue in 2007 to a mere 1% today. Similarly, sales to customers under $500 a month have dwindled from $336 million in 2007 to $153 million in 2023.

"This contraction might seem alarming at first glance. But Fastenal hasn't simply lost these customers; they've strategically chosen to de-emphasize them. This deliberate shift allows the company to focus on a different breed of customer: the larger, more complex organizations who are ripe for deeper integration with Fastenal's suite of growth drivers."

Think of it this way: vending machines, RFID-enabled bins, and Onsite locations are powerful tools for optimizing supply chains and driving efficiency. But they hold little appeal for the casual walk-in customer or the small business with simple needs. By shedding its smaller customer base, Fastenal clears the way to focus on a customer segment where these growth drivers become game-changers.

The evidence of this shift is already starting to emerge. While Onsite signings lagged in 2023, Fastenal achieved record growth in its warehousing sector, representing sales to fulfillment centers of retail-oriented companies. This sector has exploded from less than 1% of sales pre-pandemic to 3-4% in 2023, fueled by Fastenal's ability to leverage its vending platform and safety expertise to become a vital supply chain partner.

This success in the warehousing sector points to a broader trend: Fastenal is gaining traction with larger, more sophisticated customers who demand a higher level of service and integration. These are the customers who can fully capitalize on the power of Fastenal's growth drivers, leading to deeper penetration, higher spend per customer, and ultimately, more robust market share gains.

The key question for investors is whether Fastenal can maintain this momentum. While a sub-50 PMI and a sluggish overall economy present headwinds in the short term, the company is confident that its recent leadership changes and a renewed focus on growth will drive stronger results in 2024.

Hypothesis: Fastenal's Sales Growth Re-acceleration in 2024

Fastenal's sales growth will re-accelerate in the second half of 2024, driven by a rebound in the industrial economy and renewed strength in Onsite signings. This growth will be further amplified by increased penetration and higher spend per customer among its larger, more sophisticated customers.

Supporting Evidence:

Easier comparisons: As we move into the second half of 2024, Fastenal will face easier year-over-year comparisons, easing some of the pressure on growth rates. Improved execution: The leadership changes made in 2023 are already showing signs of taking root, as evidenced by the company's record FMI signings and strong performance in its contract business. Pent-up demand: With channel inventories rightsized and customer outlooks becoming more optimistic, there is likely pent-up demand waiting to be unleashed as the economy recovers.

Visualizing the Shift: Customer Size vs. Revenue

This hypothetical chart, based on data from the earnings call, shows how Fastenal is shifting its focus from smaller to larger customers.

Fastenal's quiet revolution in its customer base might be flying under the radar for now. But it has the potential to be a powerful catalyst for explosive growth in the years to come. Investors who are willing to look beyond the surface and understand the long-term implications of this strategic shift could find themselves handsomely rewarded.

"Fun Fact: Did you know that Fastenal's first Onsite location wasn't a strategic decision but a happy accident? Back in the 1990s, unable to find a building to rent in a particular town, they were offered space by a customer. This serendipitous event sparked the idea for a business model that has now become central to Fastenal's growth strategy."
