The late launch of new 5G phones caused Apple Inc’s customers to put off buying new devices, leading the company on Thursday to report the steepest quarterly drop in iPhone sales in two years.

Apple fell over 5% at one point in after-hours trade, wiping $100 billion from its stock market value, Report says, citing Reuters.

Even as booming sales of Macs and AirPods boosted overall revenue and profit above what analysts had expected, iPhone sales dropped 20.7% to $26.4 billion.
