The switch maker's stock had fallen $0.28 (6.86%) to $3.80 in early afternoon trading on Thursday. The stock has lost 51 percent of its value since January 2.
The company's financial troubles -- and its delay in restating past quarterly earnings -- caused Nasdaq to go through with a delisting, even after the exchange had granted the company some leeway regarding filing deadlines. Sonus shares will likely be quoted on the National Quotation Service Bureau (the "Pink Sheets") until the shares become eligible for trade on the OTC Bulletin Board, Sonus says.
"Our rules require the company to notify the public of decisions such as this," says a Nasdaq spokesman. "Our policy prohibits us from providing additional comment."
Sonus is still trying to right itself after a searing financial scandal that has already led to the dismissal of the company's CFO. Sonus did not respond to requests for comment.
