- Nidec’s accounting issues resulted in a 160.7 billion yen negative profit impact, heavily driven by its automotive division.
- Additional misconduct cases and major impairment losses highlight ongoing financial and governance challenges.
Nidec has disclosed the final findings of a third-party investigation into its accounting irregularities, revealing a significant financial impact accumulated over several years. The report, released on April 17, highlights that the company’s net profit was negatively affected by 160.7 billion yen from before fiscal year 2019 through the April–June quarter of 2025. A substantial portion of this impact came from its automotive business segment, emphasizing the financial strain within one of its key growth areas.
Automotive Business Drives Majority of Financial Impact
The investigation identified that the automotive division alone accounted for a negative 72.3 billion yen contribution to the total losses. This segment, which plays a crucial role in Nidec’s strategic expansion into mobility solutions, has therefore emerged as a major source of financial concern. Despite these losses, the company reported net assets of 1,679.5 billion yen as of the end of June 2025, indicating that while profitability has been affected, overall asset strength remains relatively intact.
Impairment Losses and Asset Write-Downs
Earlier disclosures on March 3 confirmed that Nidec would record impairment losses of approximately 250 billion yen. These losses are largely tied to fixed assets within the automotive business, reflecting reduced asset value and weaker-than-expected performance. The situation remains unchanged following the final investigation report, reinforcing the scale of financial adjustments required to align reported figures with actual performance.
Additional Misconduct Cases Identified
Subsequent investigations conducted after the February 27 report uncovered multiple additional instances of misconduct. One highlighted case involved overstated sales figures at Nidec Drive Technology, a subsidiary specializing in speed reducers and press equipment for industrial applications. These findings indicate that the scope of irregularities extended beyond initial assessments, raising further concerns about internal controls and reporting accuracy across business units.
Accountability and Leadership Responsibility
The report maintained its earlier conclusions regarding leadership accountability. While the court did not find direct evidence that founder Shigenobu Nagamori instructed the accounting fraud, it reiterated that he should bear the greatest responsibility for the situation. This stance underscores the importance of governance oversight and executive accountability in preventing such systemic issues within large organizations operating in Japan and globally.
Unchanged Recommendations for Future Prevention
The analysis of root causes and the recommended corrective measures remain consistent with earlier findings. These include strengthening internal controls, improving transparency in financial reporting, and reinforcing compliance mechanisms across subsidiaries. The persistence of these recommendations signals that while the investigation has concluded, the implementation phase will be critical in restoring stakeholder confidence and ensuring long-term operational stability.
