This segment groups health-care businesses by the economic engine behind the exposure: discovery tools, drug development, scaled pharma manufacturing, or patient-service delivery. The risk profile changes sharply across those layers.

For 13F readers, the tag helps separate long-duration clinical optionality from cash-flowing service or product businesses. It also makes it easier to see when a fund is taking scientific risk versus reimbursement, utilization, or platform-consolidation risk.
