Intel Corp., the world’s largest semiconductor maker, slashed its third-quarter sales prediction amid declining demand for personal computers from corporate customers in a weakening economy, Bloomberg reported. Sales will be $12.9 billion to $13.5 billion, down from a prior projection of $13.8 billion to $14.8 billion, the Santa Clara, Calif.-based company said in a statement Friday. Analysts on average had estimated sales of $14.2 billion, according to data compiled by Bloomberg. PC makers are reducing orders for Intel’s chips at a time of the year when they normally buy more to build products for the holiday shopping season. Intel said demand for chips used in business machines and orders in emerging markets are worse than expected, compounding concern that the PC market may not grow this year as consumers flock to smartphones and tablets.
