Shares of Apple fell by 4% on Tuesday following reports that the company is facing significant engineering challenges in developing its much-anticipated foldable iPhone.
According to sources cited by Nikkei Asia, Apple and its supply chain are working under tight deadlines, but current solutions are not sufficient to fully overcome the technical hurdles. The report suggests that additional time will be required before the device is ready for production.
The foldable iPhone was widely expected to debut alongside the iPhone 18 at Apple’s September 2026 launch event. However, these delays could push back the timeline. Apple, which recently marked its 50th anniversary, has consistently introduced four new iPhone models each year since 2020.
The period from April to early May is considered crucial for resolving these engineering issues ahead of production, according to the report. Meanwhile, rival Samsung, which launched its first foldable phone in 2019, continues to lead in this segment.
Despite the setback, analysts note that iPhones remain central to Apple’s business, contributing more than half of the company’s $143.8 billion revenue reported for the first quarter of fiscal 2026.
The report also clarified that the ongoing global memory chip shortage is not a factor behind the delay in Apple’s foldable device.
