Sumitomo Corporation has fully acquired ActivStyle, LLC. This company is based in the U.S. and provides home medical supplies for people with chronic conditions. The acquisition wrapped up in May 2025, done by Sumitomo Corporation of Americas, the Group’s U.S. subsidiary. This is called the “Sumitomo Corporation Group.”
This development comes after the Group decided in April 2025 to boost its equity stake in Vast Medical Holdings. Vast Medical is the parent company of Quest, which provides home medical equipment, supplies, and services for diabetes patients. The Group wants to use the strengths of ActivStyle and Quest. They plan to sell products and services that complement each other.
Chronic health issues, such as diabetes, are a growing challenge for U.S. healthcare. Incontinence, which often comes with aging and diabetes, affects over 25 million Americans. This is about 8% of the population and is rising by 2–5% each year. As these trends go on, more people will need in-home medical support and supplies.

Sumitomo Corporation entered the U.S. healthcare market in April 2024 by investing in Vast Medical Holdings. This move leverages the Group’s worldwide knowledge of home pharmaceutical services in Japan. It also leverages managed care operations in Southeast Asia.

They were happy with their initial investment and wanted to speed up business growth.

ActivStyle and Quest are working together. Sumitomo wants to improve patient outcomes and make healthcare spending more efficient. The Group will use insights from the U.S. to improve its work in Japan and Southeast Asia. This aims to boost regional synergies.
