Nidec held its first shareholder meeting on June 18 after accounting fraud surfaced in September 2025. Cumulative profit overstatements reached 160.7 billion yen through June 2025. Shareholders voiced anger at founder Shigenobu Nagamori and criticized outside directors for failing to detect misconduct. The company faces questions about whether new management can restore investor confidence.
What Shareholders Demanded at the Meeting
Shareholders called for damage claims against Nagamori and labeled outside directors as incompetent. One shareholder said they had lost faith in the company’s culture. The meeting revealed deep frustration over governance failures that allowed fraud to persist undetected for years. President Koji Kishida acknowledged quality misconduct discovered in May 2026.
Why Outside Directors Failed to Act
Outside directors received information only through official company channels and did not actively seek additional data. The audit committee, which should have caught irregularities, functioned as a rubber stamp. Outside directors lacked business experience and relied on prepared materials rather than independent investigation. Tokyo Stock Exchange rules require directors to proactively obtain information and request additional disclosures.
Leadership Changes and Governance Reform
Nagamori resigned from his role as Global Group Representative in December 2025 and stepped down as honorary chairman in February 2026. The shareholder meeting approved removal of his title from company bylaws. Auditors failed to function as market watchdogs, allowing management pressure to drive the fraud. The company nominated 12 new board members to rebuild trust.
The Scale of the Fraud
Cumulative profit overstatements totaled 160.7 billion yen through the June 2025 quarter. Quality issues also emerged alongside accounting irregularities in May 2026. The company delayed its annual report filing to September 2026 to complete investigations. Both problems exposed systemic failures in internal controls and risk management.
Final Thoughts
Nidec’s shareholder meeting exposed governance collapse that allowed 160.7 billion yen in fraud. With founder Nagamori removed and new directors installed, investors must monitor whether reforms actually strengthen oversight or remain cosmetic.
