Senko Group Holdings, the Tokyo Prime-listed logistics operator (stock code 9069), bought back treasury shares on December 5, 2025 in an amount that exceeded the distributable amount calculated under Japan's Companies Act and the associated Companies Calculation Rules. The company disclosed the breach on June 1, 2026, when it said it had set up a third-party committee and had now received the committee's investigation report.
Acting on the committee's recommendations, Senko's board resolved a set of internal-control fixes at a meeting on July 17, 2026. The company will rewrite its job-authority tables to spell out who signs off on surplus-disposal, dividend and treasury-share-buyback decisions, and revise its division-of-duties rules to name the department responsible for calculating the distributable amount itself. It is also drafting standardized process manuals covering both that calculation and the payout decisions that depend on it, training staff and directors on the relevant Companies Act and financial-instruments rules, and requiring that legal calculation checks and outside-expert consultations be written directly into board meeting materials before any future buyback or dividend goes to a vote.
Senko said the December breach has no impact on its financial statements or earnings forecasts. The company called the episode a serious matter and said it would keep strengthening its internal management systems as the new rules take effect.
