Pro-Dex (PDEX) Major Customers

Pro-Dex (PDEX) primarily sells to other companies, operating on a Business-to-Business (B2B) model. Its core business involves providing design, development, and manufacturing services for medical device manufacturers and other technology companies.

While Pro-Dex's financial filings indicate a significant concentration of revenue from a limited number of customers, the company does not publicly disclose the specific names of these major customers in its SEC filings (such as the 10-K reports), typically citing confidentiality agreements.

For example, in its most recent annual report, Pro-Dex stated:

• Sales to its top five customers accounted for approximately 74% and 79% of total net revenues for the fiscal years ended June 30, 2023 and 2022, respectively.
• During the fiscal year ended June 30, 2023, two customers individually accounted for 20% or more of net revenues, representing approximately 25% and 21% of net revenues, respectively.
• During the fiscal year ended June 30, 2022, three customers individually accounted for 10% or more of net revenues, representing approximately 29%, 22%, and 11% of net revenues, respectively.

Therefore, while Pro-Dex relies heavily on a few large customers, their specific identities (company names and symbols) are not publicly available information from the company's disclosures.

The primary category of companies it serves consists of:

• Medical device manufacturers (OEMs - Original Equipment Manufacturers)
• Other technology companies requiring precision manufacturing and design services

Pro-Dex (PDEX) is expected to drive future revenue growth over the next 2-3 years through several key initiatives and market dynamics:

1. Continued Sales of Next-Generation Orthopedic Handpiece: The company has experienced significant growth from the sales of its next-generation orthopedic handpiece, particularly to its largest customer. This product has been a primary engine of recent growth, with sales contributing meaningfully to both quarterly and full-year results, and this trend is anticipated to continue.
2. Expanded Manufacturing Capacity: Pro-Dex has invested in a new operational building, effectively doubling its manufacturing capacity. This expansion in machining and assembly capabilities is expected to support increased demand and facilitate higher order fulfillment.
3. Robust Order Backlog: As of June 30, 2025, Pro-Dex reported a record order backlog of $50.4 million. This substantial backlog is expected to underpin continued revenue and operating income growth into fiscal year 2026.
4. New Product Development and Commercialization: The company is actively investing in future growth and product development, with plans for additional product sales as development projects currently in final testing phases move into commercialization.
5. Customer Base Diversification: While Pro-Dex currently has a high concentration of revenue from a single large customer, management intends to diversify its customer base. Successful expansion to new customers would reduce dependency and open new avenues for revenue growth.
