Apple supplier Foxconn said it would resume normal production in China by the end of the month and that more than half its seasonal workforce in the country had restarted work following the coronavirus outbreak.

The Taiwanese firm, which assembles Apple’s iPhones, however, said it was unable to predict the virus’ actual impact on its full-year results.

“Prevention of outbreak, resumption of work and production are our top priority,” Chairman Liu Young-Way told an online investor conference on Tuesday.

Apple, Foxconn’s top client, rescinded its March quarter sales guidance due to a slower-than-expected ramp up of manufacturing sites in China amid travel restrictions and an extended Lunar New Year break.

But on Tuesday, Young sought to reassure investors and said there were no big problems with the supply chain and that Foxconn was helping suppliers resume work.

Meanwhile, Foxconn is helping police investigate the off-campus death of a worker employed at its “iPhone City” manufacturing complex in central China.

The company said a male employee was found dead on Monday outside an apartment building in Zhengzhou. The company also said that there are no confirmed Covid-19 cases on any of its campuses.
