Pro-Dex Inc (NASDAQ: PDEX) is a medical device company that designs, develops, and manufactures autoclavable, battery-powered, and electric multi-function surgical drivers and shavers used primarily in orthopedic, thoracic, and craniomaxillofacial markets. Revenue is almost entirely transactional, generated through product sales and contract manufacturing under development and supply agreements with OEM customers. In fiscal 2025, 99% of revenue came from medical device products and related services, per the 10-K filed September 4, 2025. The company operates as a contract design and manufacturing partner to large surgical device companies, competing against other medical device manufacturers and against customers' own internal development groups. Pro-Dex is headquartered in Irvine, California, with an additional assembly and repairs facility in Tustin, California. Customer concentration is material: a single largest customer has a long-term supply agreement covering surgical handpieces, with a next-generation handpiece launched during fiscal 2025.

Revenue model

Transactional product sales under long-term development and supply agreements. Customers either commission Pro-Dex to design and manufacture custom surgical devices or engage the company as a contract manufacturer for their own designs. Engineering, quality, and regulatory consulting services represent a secondary revenue stream. Revenue is recognized on shipment or delivery under specific purchase orders.

Products and services

Autoclavable, battery-powered, and electric multi-function surgical drivers and shavers. Rotary air motors are also sold. The company provides engineering, quality, and regulatory consulting services. Custom surgical handpiece design and contract manufacturing are core service offerings.

Customers and end markets

Primary end markets are orthopedic, thoracic, and craniomaxillofacial surgery. Customers are OEM surgical device companies that either outsource design and manufacturing or use Pro-Dex as a contract manufacturer. Customer concentration is high: one largest customer holds a supply agreement through calendar 2025 and launched a next-generation handpiece during fiscal 2025. Loss of a significant customer is cited as a principal business risk in the FY2025 10-K.

Geographic exposure

Operations are based in Irvine and Tustin, California. The filing does not specify international revenue breakdown, though the company sources raw materials and components from a global supply chain including foreign countries, exposing it to U.S. import tariff risk as of fiscal 2025.
