Notice of Initial Inclusion in the ESG Investment Index "FTSE Blossom Japan Index"

We are pleased to announce that Optorun Co., Ltd. has been selected for the first time as a constituent of the "FTSE Blossom Japan Index," a stock index targeting Japanese companies actively engaged in ESG (Environmental, Social, and Governance) initiatives.

The "FTSE Blossom Japan Index," constructed by global index provider FTSE Russell, is designed to evaluate and measure Japanese companies demonstrating strong ESG practices. This index is also adopted as an ESG index for passive investment by the Government Pension Investment Fund (GPIF), which actively promotes ESG investing.

Furthermore, our company was also selected as a constituent stock for the "FTSE Blossom Japan Sector Relative Index" in June 2025.

Since our founding, Optorun has aimed to "contribute to an advanced information society by challenging the limits of thin-film technology." We have been committed to integrating ESG perspectives into our business operations to remain a trusted company within society.

We will continue to contribute to the realization of a sustainable society and strive to further enhance our corporate value.
