May 9, 2026 -- Mitsui & Co., Ltd. (Mitsui) and Ceva Santé Animale SA (Ceva) today announce the creation of Ceva Bussan Animal Health (Ceva Bussan), a new joint venture that brings together Bussan Animal Health (BAH) and Ceva Japan. As part of the transaction, Mitsui has transferred 60% of its shareholding in BAH to Ceva. Mitsui and Ceva work together as strategic partners to drive growth in the Japanese animal health market.

In parallel, Mitsui has made an additional equity investment in Ceva, further reinforcing the long-standing partnership between Mitsui and Ceva.

Strengthening the strategic collaboration between Mitsui and Ceva

Mitsui and Ceva have built a long-standing strategic partnership in the animal health sector, combining Mitsui's extensive global reach and diverse business portfolio with Ceva's global expertise as the world's fifth-largest animal health company by sales.

This enhanced partnership is intended to accelerate collaboration across broader global initiatives, including the creation of new products and technologies, market expansion and the creation of long-term sustainable value in the animal health industry.

Ceva Bussan represents a cornerstone of this reinforced collaboration, providing an operational platform in Japan.

Ceva Bussan: A strengthened platform to support growth in the Japanese market

Ceva Bussan will offer a broader and more comprehensive product portfolio in the Japanese market by combining BAH's 75-year heritage, expertise and brand strength in the Japanese animal health market, together with its nationwide technical sales organization covering veterinary clinics across Japan, with Ceva's long-established animal health business platform as a leading global animal health company, as well as access to its key livestock and companion animal products and new and next-generation pipelines.

Through this initiative, Mitsui will strengthen its animal health business platform in Japan and pursue the introduction of overseas products, as well as the global expansion of domestically developed products and intellectual property. By creating synergies between these efforts and Mitsui's broad portfolio of business assets—including animal nutrition—and its extensive global network, Mitsui aims to contribute to the sustainable development of the global animal health industry.
