About Nidec

Nidec Corporation is a Japan-based global manufacturer of electric motors and related components that serves the automotive, industrial, and consumer electronics sectors.

The company manufactures electric motors and related components for global markets. Its shares trade in the United States as American Depositary Receipts (ADRs) under the ticker NJDCY.

Potential Concerns Under Investigation

Attorneys are reviewing whether Nidec and its management made false or misleading statements or failed to disclose material information about the company’s financial health, accounting practices, and internal controls between September 2024, and October 2025.

Between September 2024 and August 2025, Nidec appeared to emphasize steady growth and operational stability. For example, in October 2024, the company reported what it described as record first-half sales and profits, maintaining an optimistic full-year outlook amid demand for motors and cooling systems, including those used in AI-related applications.

However, based on later disclosures suggest accounting or internal control concerns may have been developing within certain subsidiaries during this time, though they were not publicly known until September 2025.

Key Timeline of Events

On September 3, 2025, Nidec announced that it had formed an independent committee to investigate “suspected improper accounting” related to a transaction at a subsidiary in Zhejiang, China. The company stated that certain group companies may have engaged in improper accounting with the involvement or knowledge of management.

Following this disclosure, the company’s stock dropped as much as 22% during intraday trading and roughly 17% by the close of trading on September 4, 2025.

On September 26, 2025, Nidec reported additional irregularities, including cases in which export values were declared lower than the appropriate amount without legitimate reason. The company also disclosed that its external auditor had issued a disclaimer of opinion due to ongoing investigations.

On October 23, 2025, Nidec withdrew its full-year 2025 forecast, canceled its year-end dividend, and suspended its share-repurchase program, citing “material non-public information” uncovered during the accounting review. Following this news, the 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, citing significant weaknesses in internal management and financial controls. The company’s stock fell another 19% following this announcement, and by late October 2025 it had lost roughly one-third of its market value since early September.

Lawyers are investigating whether Nidec’s earlier public statements about record sales and profits accurately reflected the company’s financial condition in light of the internal accounting reviews. The investigation will also assess whether management was aware of or failed to disclose known control issues or accounting irregularities before investors suffered losses.

Your Rights and Next Steps

This is an ongoing investigation and not a filed lawsuit. Investors who purchased or otherwise acquired Nidec securities during the relevant period and suffered losses may have legal rights. If evidence shows that investors were misled, the matter could lead to a class action lawsuit seeking recovery for affected shareholders.
