From technology giants like IBM and Intel to smaller--but growing--tech firms like Adtran and F5 Networks, a lengthy list of technology companies announced quarterly earnings results this week. Overall, earnings season is shaping up well. Sure, some technology companies are suffering from isolated hiccups. But the IT market, as a whole, looks healthy. Here's a look at the Adtran, F5, IBM and Intel results.

Among the earnings worth watching...

ADTRAN -- Q4 2011 for the networking company:
  • Quarterly Revenue: $175.3 million, up from $165.3 million last quarter, representing a near 6 percent increase year over year.
  • Net Income: Net income was $31.2 million for the quarter compared to $36.9 million for the fourth quarter of 2010, representing a 13 percent dip year over year. However, the earnings results beat analyst expectations.
  • Outlook: ADTRAN's outlook is optimistic, with CEO Tom Stanton attributing ADTRAN's sales of broadband access technology as a major growth factor, but expenses were incurred from the acquisition of Bluesocket.
F5 Networks -- Q1 2012 for the applications delivery specialist:
  • Quarterly Revenue: (GAAP) Revenue was $322.4 million, up from $268.9 million in the corresponding quarter last year, representing a 19.9 percent jump year over year.
  • Net Income: (GAAP) Net income was $66.5 million up from $55.7 million in the first quarter a year ago, showing a bump of 17.6 percent year over year. Analysts were impressed and F5's stock jumped sharply.
  • Outlook: Strengthened sales in North America, EMEA and APAC "exceeded expectations" and helped propel F5 Networks to continuing growth.
IBM -- Q4 2011 results:
  • Quarterly Revenue: (non-GAAP) Revenue hit $29.5 billion, a jump of 2 percent year over year.
  • Net Income: (non-GAAP): Net income hit $5.6 billion, up 5 percent year over year.
  • Outlook: New IBM CEO Ginni Rometty believes IBM is well equipped to meet all 2012 expectations, and the company's stock jumped based on IBM's strong outlook.
Intel -- Q4 2011 results:
  • Quarterly Revenue:  (non-GAAP) Revenue hit $13.9 billion, representing a boost of 22 percent year over year.
  • Income Growth: (non-GAAP) Net income came in at $3.4 billion, showing growth of 11 percent year over year.
  • Outlook: Despite worries that hard drive shortages would damage earnings, Intel had a record year, "eclipsing all annual revenue and earnings records," according to Intel CEO Paul Otellini.
The VAR Guy has just one thing to say: Those late 2011 financial results and earnings statements suggest 2012 is off to a strong start, a good sign for VARs as they seek to boost their own sales going forward.
