AMD Cuts Guidance on Chipmaking Troubles

Chipmaker Advanced Micro Devices just reduced its outlook for the current quarter, saying it now expects sales to grow in the 4 to 6 percent range, down from prior guidance of 10 percent or more. Also, gross margins will be 44 to 45 percent, lower than previously forecast. AMD blamed manufacturing difficulties at its former fabrication arm, GlobalFoundries, for the reduced expectations. AMD stock was down almost 8 percent in after-hours trading.
