Medline is the largest U.S. provider of medical-surgical products and supply chain services, selling to healthcare providers across hospitals, surgery centers, physician offices, and post-acute facilities. Medline's catalog covers roughly 335,000 products — surgical procedure kits, exam gloves, wound care, incontinence supplies, gowns, lab consumables, and diagnostic equipment — sold under its own Medline brand as well as distributed from over 1,300 third-party national brand suppliers. Medline sells primarily through multi-year "Prime Vendor" contracts, where a healthcare facility agrees to buy the vast majority of its med-surg needs from Medline, consolidating its supply chain with a single partner. The core profit driver is brand conversion: once a Prime Vendor agreement is in place, Medline systematically moves customers from third-party national brands to its own lower-priced but higher-margin Medline Brand equivalents, capturing both manufacturing and distribution margin. Medline manufactures roughly one-third of its own-brand products across 30 facilities, and sources the remainder from over 600 global partners. The company's owned logistics network — 70 global distribution centers, 2,100+ delivery trucks, and 26M+ sq ft of warehouse space — enables next-day delivery to 95% of its U.S. customer base. Growth comes from signing new Prime Vendor customers, particularly in underpenetrated non-acute settings, and from deepening brand conversion within existing accounts. Medline reports a greater than 98% Prime Vendor retention rate over the past five years.
