Announcement of Price Revisions for Applicable Products

Otsuka Pharmaceutical Co., Ltd. has announced revised prices for products listed below. The new pricing will be applied to products shipped from February 1, 2023.

To date, we have succeeded in maintaining prices and stable product supply through enhanced production efficiency, rationalization of management, and other company-wide efforts. However, increases in raw materials and energy costs have made it difficult to maintain current prices through corporate efficiencies alone, necessitating our decision to increase prices for specified products.

Otsuka Pharmaceutical will continue efforts to reduce costs while providing a stable supply of reliable, high quality products manufactured to strict safety standards.

Applicable Products (with some exceptions):

Calorie Mate (New pricing: Manufacturer's suggested retail price + 10.0%)

SOYJOY (New pricing: Manufacturer's suggested retail price + 8.7%)

Nature Made (New pricing: Manufacturer's suggested retail price + 14.8% or more)

Effective Date of Price Revision:

From Wednesday, February 1, 2023 (product shipping date)
