Dialog Semi down 17 percent on Apple warning; sector peers flag

[June 01, 2018]  FRANKFURT (Reuters) - Shares in Dialog Semiconductor fell by 17 percent on Friday to a four-year low after the Anglo-German chipmaker said its main customer Apple would cut orders for its power-management chips by around 30 percent this year.

The news also hit other European semiconductor stocks in Apple's smartphone supply chain at the open before they recovered some of their trading losses.

Austria's Ams AG shed 1.4 percent while STMicroelectronics fell by around 0.4 percent in Paris.

Dialog told investors on Thursday evening that Apple now planned to source the main power-management chips (PMICs) for one of its three new iPhone models from two suppliers instead of just from Dialog.

The reduced order volume would shave 5 percent off Dialog's 2018 revenues, although the company said it still expected to achieve year-on-year growth.

"Apple has opened the Pandora's box," said one trader in Frankfurt, adding that this may mark a trend of diminishing sales to Apple that could catch Dialog early in its efforts to diversify away from the U.S. consumer tech giant.

Baader Helvea analyst Guenther Hollfeder said the announcement was a surprise and reflected poor visibility in Dialog's relationship with Apple, which accounted for 77 percent of group sales in 2017.
