Business
DIO Corporation (039840.KQ) manufactures and sells dental implants, digital dental solutions, and related medical devices primarily in South Korea and internationally; it also provides parking systems and steel structures for buildings. Founded in 1988 and headquartered in Busan, South Korea, the company operates through its medical equipment division, which offers core implant systems including UFII internal submerged and non-submerged types, FTN external systems, Protem implants, UV Active implant systems with vacuum UV surface treatment for enhanced osseointegration, and hybrid surface treatment technologies; digital dentistry products such as the PROBO 3D printer, DIO NAVI flapless guide system, full arch rehabilitation solutions, and orthodontic tools like DIO ORTHOnavi; additional dental lasers, surgical instruments, whitening foam toothpastes, children's foam toothpastes, foam cleansers, and cardiovascular medical devices; as well as its parking system division serving domestic and export markets. The company maintains production facilities and sales networks across more than 12 countries, including joint ventures in India and subsidiaries in China and Mexico, targeting dentists, clinics, and healthcare providers globally. In recent developments, DIO launched the UFIII implant system in select regions during 2025 following its earlier introduction in Korea, continues workforce and management restructuring initiated in 2023-2024 to strengthen financial soundness by reducing receivables and debt while expanding export sales networks, and announced an equity buyback program in May 2025 that expired after repurchasing 3.89% of shares for approximately KRW 10 billion.
