Apple Shares Fall 4% as Rising Memory Costs Threaten Gross Margins
Apple shares fell 4% in premarket trading, losing $170B in valuation. CEO John Ternus warned rising memory costs will reduce gross margins to 45-46% in Q4, down from 47.9% in Q3. Despite record iPhone revenue of $57.58B in Q3, higher component costs and operational expenses threaten profitability. Apple trades at 35x forward earnings, higher than peers like Alphabet and Microsoft.
