Apple is warning investors it won't meet its second-quarter financial targets.
It is because the coronavirus alert in China has cut production of iPhones.
All of its manufacturing facilities are outside Hubei province, the epicentre of the outbreak, and all have been reopened.
Shares slipped in Asia on Tuesday as the impact from the outbreak deepened, with news of China’s possible postponement of major events coming alongside Apple saying it would fail to meet its profit target since the virus has affected iPhone production.
But the firm says production is ramping up slowly.
