A look at recent tech-industry earnings

Here is a summary of recent earnings and reports for selected technology companies and what they reveal about the state of spending and the overall economy:

April 6: Samsung Electronics Co. says it is expecting a record operating profit of $5.1 billion for the first quarter. It says the result would be a 97 percent rise from its operating profit a year earlier. Samsung estimated that its first quarter sales rose 21.6 percent from a year earlier. More details will come when Samsung releases its full quarterly results.

April 12: Google Inc. reports adjusted earnings and adjusted revenue that beat expectations. Google's revenue was helped by a 39 percent increase in "paid clicks," but the prices of its search-driven text ads continued to decline. CEO Larry Page called the first quarter "very strong," but acknowledged there's more work to do.

Tuesday: Yahoo Inc.'s first-quarter earnings show signs of modest progress under recently hired CEO Scott Thompson. Net income grew 28 percent from the same time last year and exceeded expectations. Revenue grew less than 1 percent, but represented a breakthrough because the company's revenue has been steadily falling for years.

IBM Corp. says first-quarter net income grew 7 percent, helped by strong profit margins in its services business and strong revenue growth across its software and services businesses. Revenue was flat overall because of declines in the hardware and financing segments, and revenue fell short of analysts' expectations. IBM increases its full-year guidance to at least $15 per share, above the $14.93 expected by analysts.

Intel Corp. says its net income in the first quarter fell 13 percent as spending on research and marketing rose while sales were flat.
