Apple may not be able to meet demand for the highly anticipated iPhone X until the first half of 2018, according to a note from a top analyst obtained and reported by Apple Insider.

Ming-Chi Kuo of KGI Securities said in the note to investors he now estimates Apple will be able to produce just 40 million handsets before the end of the year, down from an earlier estimate of 50 million.
