Margins: Gross margin compressed 50 bps to 44.8% due to customer mix shift toward larger accounts and 30 bps price/cost headwind. Operating margin expanded 80 bps to 21.5% as SG&A expense leverage of 130 bps more than offset the gross margin pressure.
Watch Items from the Filing
Contract customers now represent 76.5% of Q3 sales (up from 73.8% prior year), concentrating revenue with larger multi-site and national accounts that carry lower margins.
Tariff uncertainty remains; company estimates Q3 2026 tariff impact was immaterial, but acknowledges exposure will increase as lower-tariff inventory depletes and is replaced with new tariff-subject inventory.
Gross margin headwind from price/cost of 30 bps in Q3, improving only 10 bps from Q2's 40 bps headwind despite gross sourcing savings and supplier rebates.
Digital Footprint sales (FMI + non-overlapping eBusiness) comprise 61.4% of Q3 revenue; FMI device installations at 143,878 MEUs, up 7.4% YoY but annual signing goal reduced from 28,000–30,000 to 27,000–29,000 MEUs.
