How chips, PCs, services companies are faring

Seagate and AMD have issued warnings about revenue for the latest quarter, and Intel says the weak economy is slowing growth. Several other companies providing computers, components, services and related software are releasing guidance and quarterly earnings reports in the coming weeks.

Here's a look at how selected companies are faring:

- July 5: Seagate Technology PLC warns that its quarterly revenue will fall below expectations, after shipping fewer hard drives than expected partly because of a quality issue with a supplier for its business product lines. The company also said its rivals recovered faster than expected from disruptions caused by last fall's heavy flooding in Thailand. That meant Seagate had to cut back on shipments.

- July 9: Chipmaker Advanced Micro Devices Inc. says it's lowering its guidance because of weaker-than-expected sales in China and Europe and lackluster demand overall from consumers.

- July 12: Printer maker Lexmark International Inc. says it fared worse during the second quarter than management anticipated, providing the latest evidence of a weakening economy.

- Tuesday: Intel Corp., the world's largest chipmaker, says the weak global economy is slowing its growth, and revenue for the current quarter is likely to come in below Wall Street forecasts. Intel says consumer demand in North America and Western Europe is not recovering as fast as expected, while growth in emerging markets such as China and Brazil is slowing.
