Option Care Health is the largest independent provider of home and alternate site infusion services in the U.S. Infusion therapy involves delivering drugs intravenously, and Option Care Health enables patients to receive this care at home or in outpatient settings rather than in hospitals. The company operates a national network of 196 locations across 43 states, including 87 compounding pharmacies and over 750 infusion chairs in ambulatory suites. Clinical staff — pharmacists, nurses, and dietitians — manage the full care process, from compounding and dispensing drugs to nursing support and physician coordination. Option Care Health serves two broad therapy categories: acute therapies (IV anti-infectives, parenteral nutrition), which are short-duration, high-margin, and account for roughly 25% of revenue; and chronic therapies (immunoglobulin, inflammatory disorders, neurological conditions, rare/orphan drugs), which are recurring, lower-margin, and make up the remaining ~75% of revenue. The company generates revenue primarily through reimbursement from payers for drugs dispensed and services provided. Gross profit is driven by the spread between drug procurement costs and reimbursement rates benchmarked to AWP or ASP. Scale advantages include procurement leverage concentrated among four key vendors, and nursing efficiency from ambulatory suites, where nurses can serve multiple patients simultaneously. Option Care Health grows through acute therapy share gains, partnerships with pharma manufacturers on new rare disease drug launches, expansion of its ambulatory suite network, and tuck-in M&A.
