Nidec Shares Plunge on Report of $6.3 Billion Impairment, CEO Dismissal

Summary
Shares of Nidec Corp. plummeted, hitting their daily limit down, after a Japanese media report alleged the motor maker plans a massive ¥1 trillion impairment charge and has dismissed its chief executive.
Shares of Nidec Corp. (TYO:6594) plunged by their daily limit on the Tokyo Stock Exchange on Monday following a media report alleging the company plans to book a massive impairment charge and has dismissed its chief executive.
Allegations Trigger Sell-Off
The sell-off was sparked by a report from Japanese financial outlet Diamond Online. According to the report, the world's largest precision motor manufacturer intends to retroactively book an impairment charge of approximately ¥1 trillion ($6.3 billion) for the fiscal year that concluded in March 2026.
This figure is four times the ¥250 billion impairment that Nidec had previously indicated in March. A charge of this magnitude could potentially erase all profits the company has accumulated over the past decade.
Adding to investor concerns, the report also alleged that Nidec's board held an emergency meeting on September 25 and voted to dismiss President and CEO Mitsuya Kishida. The move is seen by the market as a sign of the severity of management accountability issues related to the accounting scandal.
Market Impact
Nidec's stock fell 17.6% to ¥2,340, hitting the Tokyo Stock Exchange’s maximum daily downside limit. The sharp decline stood in stark contrast to the broader Japanese market, with the Nikkei 225 index trading approximately 0.8% higher on the day.
AdThe combination of a much larger-than-expected impairment and the abrupt removal of its CEO has created what sources cited as a severe credibility crisis for the company, particularly as it occurs during an ongoing corporate restructuring.
What Investors Are Watching
Investors are now bracing for official company disclosures that could significantly alter Nidec's financial landscape. Several key dates are approaching:
- An announcement on new leadership is expected as early as September 29.
- The company's annual securities report is due by September 30.
- The next scheduled earnings release is set for late October.
Shareholders, who had already called for legal action, will be closely monitoring these events for clarity on the company's financial health and future direction.
