RMC Corporate Overview RMC is a Korea-based neurovascular intervention medical device and systems distribution company exclusively serving the Korea market currently. RMC distributes, but does not design or manufacture, commercial medical products, including cerebral surgical devices. Opportunity RMC distributes cerebrovascular surgery equipment in South Korea and seeks growth opportunities in South Korea for other medical device products and systems. As a rapidly aging country, demand for medical equipment is expected to accompany the rise in cerebrovascular diseases such as strokes. RMC has established close relationships with leading university hospitals and general hospitals in Korea to supply cerebrovascular surgery equipment. These relationships provide opportunities for continued sales of products distributed by RMC as well as assisting RMC in identifying demand for other medical devices that RMC may add to enhance its product portfolio. This is expected to enhance RMC’s competitiveness in South Korea. RMC has established a nationwide sales network and logistics system, enabling it to swiftly and efficiently supply products to any region in the country. This serves as a significant strength compared to competitors and is expected to contribute to building long-term trust with medical institutions.
