Nidec shares rise as much as 7.9%; Oasis reports stake

Nidec shares rose as much as 7.9% on March 11, 2026, following the disclosure that Oasis Management, a Hong Kong-based activist investor, had acquired a 6.7% stake in the Japanese motor manufacturer. The investor has called for a governance overhaul at the company, which has been embroiled in a deepening accounting scandal since June 2025. The controversy, initially triggered by alleged irregularities at an Italian subsidiary, led to delayed financial reporting and the resignation of founder Shigenobu Nagamori as chairman emeritus.

A third-party committee's findings, released earlier in the week, criticized Nagamori for fostering a culture of "excessive pressure to meet performance targets," resulting in widespread use of "creative accounting" across business units. Nidec also announced a potential ¥250 billion ($1.6 billion) writedown and faces risks of delisting from the Tokyo Stock Exchange after being removed from the Nikkei 225 index. CEO Mitsuya Kishida apologized publicly, pledged to forfeit his salary, and confirmed a separate investigation into legal accountability for past practices.

While Oasis Management's stake signals renewed investor scrutiny, Nidec's recent Q3 earnings beat and upgraded guidance have provided some market optimism. However, ongoing probes into trade compliance and governance weaknesses remain critical risks for the company's financial credibility and long-term stability.
