Apple warned investors and customers on Sunday that it expects to ship fewer iPhone 14 Pro and iPhone 14 Pro Max models as the world’s most valuable tech firm grapples with ongoing Covid-19 restrictions in China.

The company said it continues to see strong demand for the pro models of the new iPhone 14 lineup, but has slashed its earlier shipment estimates.

“The facility [located in Zhengzhou, China] is currently operating at significantly reduced capacity. As we have done throughout the COVID-19 pandemic, we are prioritizing the health and safety of the workers in our supply chain,” the company said in a blog post.

Like many firms, Apple has been navigating ways to sustain its products shipments amid a global supply chain disruption for over two years. The disclosure surrounding the shipments on Sunday is rare for Apple, which has largely chosen to make such disclosures at its quarterly earnings calls.

The update, however, doesn’t come as a surprise. Apple chief executive Tim Cook said in the recent earnings call last month that supply for the iPhone 14 Pro and iPhone 14 Pro Max have been “constrained” since launch.

“We continue to be constrained today and so we’re working very hard to fulfil the demand,” he said on the call.

The company said Sunday that it was “working closely with our supplier to return to normal production levels while ensuring the health and safety of every worker.”
