Dialogue with Stakeholders

▶ Investor Relations ｜ https://www.sumitomocorp.com/en/jp/ir ▶ Action to Implement Management that is Conscious of Cost of Capital and Stock Price｜https://www.sumitomocorp.com/en/jp/ir/investors/enhancement

We are working to strengthen engagement with shareholders, investors, and other stakeholders outside the Company following our Corporate Disclosure Policy. The Investor Relations Department has established four guidelines for its activities. These are Proactive Disclosure, Sincere Dialogue, Timely and Appropriate Sharing, and Constructive Proposals. We actively disseminate information in cooperation with internal related departments and collect opinions through dialogue. Based on feedback from these opinions, we make proposals and hold discussions to realize management conscious of the cost of capital and the stock price. Through this cycle of activities, we will deepen external stakeholdersʼ understanding of the Group and contribute to the strategy execution and value creation capabilities of all officers and employees as internal stakeholders, thereby fulfilling our stated mission of “obtaining the correct evaluation from the market and contributing to the enhancement of our corporate value.”
