Customers
FONAR sells MRI equipment primarily to private diagnostic imaging centers and hospital outpatient imaging facilities. Its service and upgrade revenue comes from the installed scanner base, while HMCA’s management business serves imaging centers and related professional corporations that need outsourced operations, billing, and administrative support. The company also targets physicians who influence scanner purchasing decisions, especially neurosurgeons, orthopedic surgeons, radiologists, and general physicians.

Strategy
FONAR’s strategy is to expand MRI utilization by improving and adding managed imaging facilities, increasing scan volume, and supporting the installed base with service and upgrades. It also seeks to widen recognition of the Upright® MRI through physician-focused marketing and product enhancements such as SwiftMR™, while maintaining a differentiated niche against larger scanner manufacturers.
Higher utilization drives recurring diagnostic-services revenue and improves fixed-cost absorption.
Service and maintenance provide recurring income and deepen customer retention.
Unique weight-bearing imaging supports a premium positioning versus standard MRI systems.
Geography
FONAR is headquartered in Melville, New York and operates primarily in the United States. Its HMCA subsidiary owns and manages six diagnostic imaging facilities in Florida, while the company also reports modest foreign revenue. Geography matters because the business is tied to U.S. reimbursement, FDA regulation, and local imaging-center economics, with Florida and New York being operationally important.
Risks
FONAR faces demand pressure from reimbursement cuts, intense competition from larger MRI manufacturers, and dependence on utilization at its managed imaging centers. The company also disclosed cybersecurity threats and a material weakness in IT controls, which could disrupt operations or increase remediation costs. Because a large share of revenue is tied to U.S. healthcare economics and third-party payer collections, changes in reimbursement, credit conditions, or payer mix can quickly affect margins and cash flow.
