SAN FRANCISCO -- Intel's ( INTC) business held up amid the global financial turmoil that marked the close of the third quarter, but the chipmaker warned that the road ahead was getting bumpy. "As we look to Q4, it is hard to know what impact the financial crisis will have on end customer demand," CEO Paul Otellini said in a statement Tuesday. The Santa Clara, Calif., chipmaker said sales in the last three months of the year will range between $10.1 billion and $10.9 billion, a range that barely meets the $10.8 billion expected by analysts. The company said it was providing a sales range that is wider than typical on account of the recent economic uncertainty and the various potential outcomes. Yet even the best outcome -- with Intel achieving the high-end of the range -- translates to weaker-than-normal sales growth for the fourth quarter. Shares of Intel were up 57 cents at $16.50 in extended trading, following a decline of more than $1 in regular trading Tuesday. While Intel had characterized demand for all of its products as strong back in July, Otellini said Tuesday that corporate spending on technology began to weaken in September and will continue to be soft in the months ahead. And cracks are appearing in consumer demand for PCs as the industry prepares for the all-important holiday sales season. "In general consumer traffic overall is light at this point in the quarter, but we do see continued healthy interest in notebooks and netbooks," Otellini told analysts in a post-earnings conference call Tuesday.
