Founded in 1999, The Ensign Group, Inc. (Ensign) is a holding company with independent subsidiaries that provide skilled nursing, senior living and rehabilitative services, as well as other ancillary businesses (including mobile diagnostics and medical transportation), in 17 states. As part of our investment strategy, we also acquire, lease and own healthcare real estate to service the post-acute care continuum through acquisition and investment opportunities in healthcare properties. For the year ended December 31, 2025, we generated approximately 95.6% of our revenue from our skilled nursing facilities. The remainder of our revenue is primarily generated from our real estate properties, senior living services and other ancillary services.
As of December 31, 2025, we offered skilled nursing, senior living and rehabilitative care services through 373 skilled nursing and senior living facilities. Of the 373 facilities, we operate 253 facilities under long-term lease arrangements and have options to purchase 8 of those 253 facilities. Our real estate portfolio consists of 158 owned real estate properties, which includes 120 facilities operated and managed by us, 38 operations leased to and operated by third-party operators, and the Service Center's California location. Of the 38 third-party operations, one senior living operation is located on the same real estate property as a skilled nursing operation that we own and operate.
The name "Ensign" is synonymous with a "flag" or a "standard" and refers to our goal of setting the standard by which all others in our industry are measured. We believe that through our efforts and leadership, we can foster a new level of patient care and professional competence at our independent subsidiaries and set a new industry standard for each patient we service. We view healthcare services primarily as a local business. We believe our success is largely driven by our proven ability to build strong relationships with key stakeholders in local healthcare communities, in part, by leveraging our reputation for providing superior care. Accordingly, our brand strategy and organizational structure promotes the empowerment of local leadership and staff to make their facility the "operation of choice" in their community. This is accomplished by allowing local leadership to discern and address the unique needs and priorities of healthcare professionals, customers and other stakeholders in the local community or market, and then work to create a superior service offering for, and reputation in, their particular community. This local empowerment is unique within the healthcare services industry.
We believe that our localized approach encourages prospective patients and referral sources to choose or recommend our local operations. In addition, our leaders share real-time operating data, clinical benchmark and operational performance metrics with their peers in order to improve clinical care, enhance patient satisfaction and augment operational efficiencies, promoting the sharing of best practices.
