"The Company reported unaudited consolidated revenue of NT$ 551.1 billion for November 2022, down 29.04 percent MoM (Month on Month) and 11.36 percent YoY (Year on Year)," read a statement issued by the company.

"Due to production gradually entering off-peak seasonality and a portion of shipments being impacted by the epidemic in Zhengzhou, revenue in November declined MoM. However, the MoM decline was roughly in line with the company's expectations," read the statement.

"At present, the overall epidemic situation has been brought under control with November being the most affected period by the epidemic," the statement said.
