The company said it received the demand under Japan's Companies Act and will decide on possible claims after the Executive Responsibility Investigation Committee reviews alleged improper accounting.
Nidec Corporation said it has received a shareholder demand under Article 847, Paragraph 1 of the Companies Act seeking legal action over improper accounting, adding an official company response to a ¥5 billion claim previously disclosed by the shareholder's attorney against nine current and former executives including founder Shigenobu Nagamori and President Mitsuya Kishida. The company said its Executive Responsibility Investigation Committee, set up on March 13, 2026, will assess whether current and former directors, auditors and executive officers bear legal liability and whether claims for damages or other remedies should be pursued. If Nidec does not sue within 60 days, the shareholder can file a derivative lawsuit on the company's behalf. The dispute follows a third-party finding of multi-year improper accounting, including avoided impairment accounting on fixed assets, that reduced cumulative net profit by ¥160.7 billion.
