What Happened?

On February 6, 2026, KDDI posted an announcement on its website entitled “Notice Regarding Expectation that Disclosure of Earnings Report for the Third Quarter of the Fiscal Year Ending March 2026 Will Exceed the 45-Day Period Following the End of Such Quarter.” The announcement stated that KDDI has “decided to postpone the disclosure of its earnings report” and that the reason for postponement was due to uncertainties regarding the quarterly results, in light of a previously announced internal investigation. On this news, the price of KDDI shares declined by $2.03 per share, or approximately 11.44%, from $17.74 per share on February 5, 2026 to close at $15.71 on February 6, 2026.

What Should I Do?

At this stage, no lawsuit has been filed. The investigation is ongoing to determine whether claims may be brought under federal securities laws.
