Wingtech Technology, the Chinese owner of chipmaker Nexperia, is facing the risk of delisting from the Shanghai Stock Exchange due to an audit failure, as the company remains embroiled in a power struggle for control of its Dutch subsidiary.

The risk was triggered after Wingtech’s auditor issued a “disclaimer of opinion”, citing restrictions in verifying the financial records of Nexperia’s overseas operations, according to a company filing to the Shanghai bourse on Wednesday.

In the Wednesday filing, Wingtech said it was working to restore its internal management system and gain full access to Nexperia China’s data to solve the audit issues.

Wingtech’s stock will be subject to a delisting risk warning starting May 6, after which trading will halt if the price fluctuates more than 5 per cent, according to the latest filing. The company could be forced to delist from the exchange if the issues are not resolved by the end of 2026.

The company’s stock and convertible bonds were also suspended from trading for one day on Thursday.
