Tibco Software, Inc. (TIBX) stock gained 3.71 percent to $27.99 in the after-market trading. Hewlett-Packard Co (HPQ) had considered buying Tibco Software until two weeks ago when talks fizzled, a Reuters exclusive report quoted sources familiar with the matter.

Schnitzer Steel Industries Inc. (SCHN) stock rose 3.11 percent to $63.26 in the after-market trading.


Micrel Inc. (MCRL) stock plunged 10.97 percent to $12.82 in the after-market trading, following a cut to its first quarter guidance. The company lowered its first quarter earnings guidance to range of about 13 cents to 14 cents a share from previous forecast of 17 cents to 19 cents a share, while Street predicts 18 cents a share. The company reduced its revenue outlook to range of minus 10 percent to minus 11 percent from previous range of minus 2 percent to minus 6 percent.

Micrel said a Korea-based customer took lesser deliveries to control inventory levels. The same was implemented by its sell-in channel partners as a result of the inventory over-build that took place in the last half of 2010. Overall demand was also impacted by disruptions in the worldwide electronics supply chain due to the earthquake and tsunami in Japan. Micrel, however, expects second quarter revenue to grow sequentially over last quarter.

Extreme Networks Inc. (EXTR) stock plummeted 10.03 percent to $3.05 in the after-market trading, as it guided third quarter revenue below Street view. The company expects third quarter revenue of $75.5 million to $76.5 million, while Street predicts $83.87 million. The company said revenue for the quarter was impacted by the deferral of $2.6 million in product revenue for a large customer and the timing of several large and relatively complex customer transactions.

We expect to be able to complete our obligations under these deals in future quarters, which will represent additional revenue for Extreme Networks at that time. In addition, we have begun to execute on our stated strategic company transformation, and have announced new products and are consolidating our product portfolio to reduce expense and eliminate under-performing or obsolete products, said Oscar Rodriguez, chief executive officer of Extreme Networks.

As a result, we experienced some customer purchase decision delays, as we worked to transition our customers to new products and architectures. Other factors impacting this quarter's results were a relative slowdown in our EMEA sales and longer sales cycles for business in the U.S., and increased competitive pressures related to customers in the horizontal enterprise IT market, Rodriguez added.
