Nidec Corp. stock dropped as much as 18% in Tokyo trading Wednesday after the company disclosed suspected improper conduct related to product quality.

The Japanese electronics manufacturer revealed the quality concerns in a regulatory filing, triggering a sharp selloff in its shares. The disclosure prompted immediate market reaction as investors assessed potential risks to the company's reputation and operations. Nidec, a major supplier of precision motors and components, did not provide detailed specifics about the nature or scope of the suspected misconduct. The company indicated it is investigating the matter internally. The 18% intraday decline reflects investor concern over product quality issues at a company whose operations span automotive, industrial, and consumer electronics sectors. Quality problems could carry significant implications for customer relationships and regulatory compliance across these markets. The company has not announced findings from its investigation or disclosed what corrective actions might be necessary. Further updates are expected as the probe progresses.
