AMERICAN SHARED HOSPITAL SERVICES

American Shared Hospital Services provides leasing and operational services for stereotactic radiosurgery and advanced radiation therapy equipment. The company's primary assets include nine Gamma Knife systems and one proton beam radiation therapy (PBRT) system deployed across multiple healthcare facilities. Beyond equipment leasing, the company offers planning, installation, reimbursement support, and marketing services to facilitate adoption and operation of these technologies by healthcare providers.

The company operates through two business segments. The Leasing segment generates revenue by providing access to Gamma Knife and PBRT systems to cancer treatment centers and health systems. The Retail segment consists of two owned and operated single-unit Gamma Knife facilities that deliver radiosurgery services directly to patients. The Retail facilities represent a vertically integrated component of the business, combining equipment ownership with clinical service delivery.

Based in San Francisco, California, American Shared Hospital Services operates with 81 full-time employees and maintains a customer base that spans both domestic and international markets. The company targets cancer treatment centers, health systems, and cancer networks as its primary customers. Founded in 1980, the company remains incorporated in California and is publicly listed on the New York Stock Exchange.
