SUZUKEN CO., LTD. (headquarters: Nagoya City, Aichi; President and CEO: Shigeru Asano; hereinafter “the Company”) previously issued a timely disclosure on February 12, 2026, regarding the establishment of Collabo CREATE CO., LTD. (headquarters: Chuo-ku, Tokyo; President: Hidetsugu Soejima; hereinafter, “Collabo CREATE”) effective April 1, through a company split of S.D. Collabo Co., Ltd. (hereinafter, “S.D. Collabo”).

We are pleased to announce that at a Board of Directors meeting held today, the Company resolved that Collabo CREATE will jointly develop a healthcare logistics business that addresses social challenges through a joint-venture structure with MITSUI-SOKO HOLDINGS Co., Ltd., Seino Holdings Co., Ltd., TOHO HOLDINGS CO., LTD., OHKI HEALTHCARE HOLDINGS CO., LTD., YAGAMI CO., LTD. ( Seiei Ailes Sante Holding Ltd.), and Miyano Medical Instruments Co., Ltd., as well as through a business alliance with SoftBank Corp.

1. Purpose and Background for Establishing the New Company

   Japan’s medicaland healthcare sector is facing increasingly complex demanddriven bya declining birthrate, an aging population, and the expansion of home- and community-based care. At the same time, supply-side constraints are intensifying, including workforce shortages, regional disparities in personnel distribution, and tightening logistics and delivery capacity—symbolized by the so-called “2024 Problem in Logistics.”

   As pharmaceuticals and medical devices become more advanced and specialized, it has become essential to meet strict requirements for quality, temperature control, lead times, and more. Concurrently, ensuring a stable supply and maintaining a reliable healthcare system, including during disasters, is reaching the limits of what a single company can achieve on its own.

   Furthermore, it has become an urgent priority to address social issues aimed at minimizing social costs and environmental impacts, including the reduction of excess inventory and waste losses, as well as lowering CO₂ emissions through collaborative operations.

   As these various challenges intensify and interact in increasingly complex ways, it has become essential to move beyond traditional industry categories—such as manufacturers, wholesalers, and medical institutions—and instead visualize issues along each domain of the value chain, including procurement, manufacturing, storage, transport and distribution, last-mile delivery, and even clinical and home-care settings. This approach enables the design and operation of solutions tailored to each challenge.

   We believe that new value will be created by building a platform that not only allows each company to leverage its strengths independently, but also integrates those strengths in a multilayered way to realize both social value (stable supply, business continuity planning [BCP], and environmental responsibility) and economic value (greater efficiency and the creation of new markets).

   In light of the above, Collabo CREATE is a collaborative enterprise formed by companies united under the shared philosophy of “contributing to society.” The name “Collabo CREATE” reflects the aspiration of participating companies to work together, bringing together their wisdom and experience to co-create new value, while also expressing the

   endorsement of each partner company.

   In addition, under a structure in which each partner company appoints part-time directors and dedicated personnel, we will combine the assets, capabilities, and expertise of our Group and of each partner company in an organic manner, enabling the effective and efficient implementation of solutions that would be difficult for any single company to achieve alone.

   Through these initiatives, we are committed to building an unparalleled healthcare logistics business that incorporates sustainability, while addressing a wide range of logistics challenges across the healthcare sector.

2. The Role of Collabo CREATE

   Collabo CREATE is a non-asset-based comprehensive solutions provider that brings together the assets, capabilities, and expertise of our Group companies and partner companies. Supported by part-time directors and dedicated personnel from each organization, we design and propose optimal logistics solutions across a broad range of healthcare challenges. In addition to ethical drugs, our scope covers healthcare products such as medical devices and supplies, diagnostic agents, nutrition-related products, and over-the-counter (OTC) products. We will respond to the needs of manufacturers,

   medical institutions, and local communities from a neutral and independent position.
