Notice Regarding Stock Split, Partial Changes to Articles of Incorporation Resulting from the Stock Split and Partial Changes to Shareholder Benefit Program

1. Purpose of the Stock Split

We recognize returning profit to shareholders as a key matter for management and has striven to enhance shareholder returns in part by maintaining stable dividends (with regard to the dividends for the fiscal year ending March 2025, plans call for a 23rd consecutive year of increase) while also dynamically conducting share buybacks that take into consideration investments in sustainable growth. As a result, KDDI shareholders currently encompass a wide range of generations. However, due to the new NISA system (tax-exempt, small-figure investment system) coming into effect in 2024, as part of long-term asset formation, we expect the expansion in investors to continue going forward.
In light of these conditions, we will reduce the size of our investment unit to make it easier and more attractive to invest in KDDI's stock. We also plan to conduct a stock split with the aim of further expanding the pool of investors who support the Company's sustainable growth.
