Shamis & Gentile, P.A. is investigating claims on behalf of investors of Nidec Corporation ("Nidec" or the "Company") (NJDCY). Impacted investors are advised to contact the firm now.

What the Investigation is About

The law firm is investigating whether Nidec and its management made statements or omissions concerning the company’s financial condition, accounting practices, and internal controls between September 2024 and October 2025. During this period, Nidec reported what it described as record sales and profits and maintained an optimistic full-year outlook amid demand for motors and cooling systems, including those used in AI-related applications. However, later disclosures suggest that accounting or internal control issues may have been developing within certain subsidiaries during this time, though they were not publicly known until September 2025.

Key Timeline

  • On September 3, 2025, Nidec announced that it had formed an independent committee to review “suspected improper accounting” related to a transaction at a subsidiary in Zhejiang, China. The company said certain group entities may have engaged in improper accounting with the involvement or knowledge of management. Following this announcement, Nidec’s stock fell as much as 22% intraday and closed down about 17% on September 4, 2025.
  • On September 26, 2025, Nidec disclosed additional irregularities, including cases where export values were declared lower than the appropriate amount without legitimate reason. The company also noted that its external auditor had issued a disclaimer of opinion due to the ongoing internal investigations.
  • On October 23, 2025, Nidec withdrew its full-year forecast, canceled its year-end dividend, and suspended its share-repurchase program, citing “material non-public information” identified during the accounting review. After this disclosure, the company’s stock declined approximately 25%, from $4.60 to $3.43 per share by market close.
  • On October 27, 2025, the Tokyo Stock Exchange placed Nidec under “special alert” status, referencing weaknesses in internal management and financial controls. The company’s stock fell another 19% after this announcement.

By late October 2025, Nidec’s stock had declined by roughly 33% from early September levels, reflecting a significant reduction in market value and investor confidence.
