Ventas, Inc. is a real estate investment trust that owns and leases healthcare properties across North America and the United Kingdom, focusing on senior housing, outpatient medical buildings, and other healthcare facilities. The company generates revenue through three main segments: operating senior housing communities through third-party managers, leasing outpatient medical and research facilities to health systems and academic institutions, and collecting rent from tenants operating senior housing and skilled nursing facilities under triple-net lease agreements. Ventas also earns fees from its investment management platform, maintaining strategic ownership stakes in major operators like Atria Senior Living, and leverages its real estate portfolio to serve the large and growing aging population while distributing cash flows to shareholders as a REIT.
