Nidec Accounting Irregularities Impact Automotive Business with ¥160.7 Billion Loss

Nidec has disclosed the final findings of an independent investigation into its accounting irregularities, revealing a substantial financial impact spanning multiple fiscal periods. The report highlights that cumulative net profit reductions from before fiscal year 2019 through the April–June quarter of 2025 reached a negative 160.7 billion yen. This development underscores the scale of financial discrepancies and their long-term implications on the company’s financial health. The automotive division emerged as a major contributor to the losses, emphasizing structural challenges within one of the company’s key business segments.

Automotive Business Drives Major Financial Impact

The automotive segment alone accounted for a negative impact of 72.3 billion yen on net profit, signaling deep-rooted inefficiencies and accounting inconsistencies within the division. These losses have also affected overall net assets, which stood at 1,679.5 billion yen as of the end of June 2025. The scale of the impact highlights the critical role of the automotive business in shaping the company’s financial stability and the urgency required to address operational and reporting issues within this segment.

Impairment Losses and Asset Write-Downs

Earlier disclosures from March 3 indicated that the company would incur impairment losses of approximately 250 billion yen, primarily linked to fixed assets associated with the automotive business. This estimate remains unchanged, reinforcing concerns about asset valuation and capital allocation decisions made in previous years. The impairment charges further compound the financial strain, reflecting both reduced asset productivity and the need for corrective accounting measures.

Additional Misconduct Identified in Investigation

Subsequent investigations conducted after the February 27 report uncovered additional cases of misconduct. According to company statements, multiple instances were identified, including overstated sales figures at Nidec Drive Technology (NDTC). This subsidiary, based in Mukō City, Kyoto Prefecture, is involved in manufacturing speed reducers and press equipment for machine tools. The findings indicate systemic lapses in internal controls and oversight mechanisms, raising concerns about governance practices across business units.

Responsibility and Governance Observations

The report maintained its earlier conclusions regarding accountability, stating that while there was no direct evidence of instruction for accounting fraud by founder Shigenobu Nagamori, he should bear the highest level of responsibility. This stance reflects broader expectations of leadership accountability in corporate governance. The recommendations for preventing recurrence remain consistent with previous findings, focusing on strengthening compliance frameworks, improving internal audits, and enhancing transparency in financial reporting processes.

Financial Impact Summary of Nidec Irregularities

The investigation outcomes highlight the need for comprehensive structural reforms within Japan-based operations, particularly in financial reporting and business oversight. While corrective measures have been recommended, restoring stakeholder confidence will depend on effective implementation and sustained governance improvements.
