About this update from Nippon Paint Holdings Co., Ltd.

Index JPX-Nikkei Index 400 (2026) We have been selected as a constituent stock of the JPX-Nikkei Index 400. The JPX-Nikkei Index 400 is composed of companies with high appeal for investors, which meet requirements of global investment standards, such as efficient use of capital and investor-focused management perspectives. The index is jointly calculated and published by JPX Market Innovation & Research and Nikkei. JPX PRIME 150 Index (2026) The JPX Prime 150 Index was developed based on the concept of representing Japan's leading companies expected to create value from among the top-ranked stocks listed on the TSE Prime Market by market capitalization and selects constituents from two perspectives of value creation: (1) equity spread, which is the difference between return on equity (ROE) and cost of equity, and (2) PBR, a market valuation that factors in future information and non-financial information.
