KDDI Restates Past Financial Data After Misconduct at Advertising Subsidiaries

An update from KDDI ( (JP:9433) ) is now available.

KDDI has revealed that inappropriate transactions were carried out by employees at its consolidated subsidiary BIGLOBE Inc. and BIGLOBE’s unit G-Plan Inc. in their advertising agency business, prompting the company to convene an external Special Investigation Committee in January 2026. The committee, made up of outside lawyers and certified public accountants, was mandated to establish the facts, quantify any impact on consolidated accounts, check for similar cases, analyze root causes, and propose governance improvements.

Following the committee’s March 31, 2026 report confirming the misconduct, KDDI has restated previously filed Annual Securities Reports and revised past Data Book performance figures to reflect the corrected numbers. The company also used this opportunity to adjust additional items that had previously been considered immaterial at the time of disclosure, signaling a broader cleanup of its historical financial data and an effort to reinforce transparency and internal controls for investors and other stakeholders.

The most recent analyst rating on (JP:9433) stock is a Hold with a Yen2918.00 price target. To see the full list of analyst forecasts on KDDI stock, see the JP:9433 Stock Forecast page.
