We assess multiple moat layers. Switching costs are high due to embedded FMI and Onsite programs that automate replenishment, reduce line-down risk, and integrate with customer workflows. Customers rarely uproot point-of-use inventory once standardized.

We score switching costs at 90. Cost advantages from dense local service, private label safety, integrated logistics, and scale DC network (including LIFT support for FMI) merit 80. Efficient scale applies in many local markets where proximity, frequent service visits, and tailored assortments favor incumbents, scored at 78. Intangibles include a respected brand, private labels, and deep category expertise at 70. Network effects are limited since value does not grow strongly with user count, scored at 35. Weighted together, this yields a strong but not impregnable moat, with the main erosion risk being large customers pressuring price and mix as Onsite and contract accounts grow, and potential encroachment from digital-first competitors. 2025 data points underpin this view: FMI represented 44.7% of sales, weighted installed devices reached 136,638, $50k+ sites rose to 2,657, and digital footprint rose to 61.4% of sales (62.4% in December).
