Acadia Healthcare is a leading provider of behavioral healthcare services in the United States, operating a geographically diverse network of inpatient psychiatric facilities, residential treatment centers, community-based recovery programs, and specialized treatment centers. The company serves high-acuity patient populations with serious mental health disorders, substance use disorders, and eating disorders, generating revenue primarily through per-diem reimbursement from Medicare, Medicaid, commercial insurance, and managed care contracts. Acadia pursues growth through facility expansion, joint venture partnerships with health systems, new facility development, acquisitions, and continuum-of-care expansion, positioning itself as a large-scale pure-play operator in a fragmented industry.
