NEW YORK ( TheStreet) -- Micron Technology ( MU) shares weakened after Thursday's closing bell after the Boise, Id.-based chip maker posted a surprise quarterly loss on flat sales and declining margins.

The company said it lost $135 million, or 14 cents a share, for the three months ended Sept. 1 on revenue totaling $2.14 billion, down from a year-ago profit of $342 million, or 32 cents a share, on revenue of $2.49 billion. In its fiscal third quarter ended in June, Micron's revenue also totaled $2.14 billion.

The average estimate of analysts polled by Thomson Reuters was for a profit of a penny per share in the latest quarter on revenue of $2.11 billion.



The stock was last quoted at $5.73, down 2.4%, on volume of nearly 800,000, according to Nasdaq.com.

Micron also gave a word of warning to investors about the coming jury decision in its antitrust case with Rambus ( RMBS), saying it can't "reasonably" estimate the range of possible losses from the suit.

"An unfavorable outcome could have a material adverse impact on the company's results of operations for the fourth quarter of fiscal 2011," Micron said.

Because of weak DRAM pricing, the company's gross margin dropped to 15% in the quarter from 22%. Micron said revenue from its NAND flash products rose 11% on a sequential basis as a 40% spike in volume offset a decline in average selling prices.

Support.com

Shares of Support.com ( SPRT) took a hit in late trades after the provider of tech support software and services forecast a wider than anticipated loss for its fiscal third quarter.

The company said it now sees a non-GAAP loss of 10 to 12 cents a share on revenue of between $12.3 million and $12.6 million for the three months ended Sept. 30. The average estimate of two analysts polled by Thomson Reuters was for a loss of 6 cents a share in the quarter on revenue of $15.7 million.

Support.com attributed the shortfall to weak retail demand and also said it's amended its deal with Comcast ( CMCSA) to provide "incremental sales revenue" for Support.com while extending the dates on warrants held by Comcast on Support.com common shares.

Support.com's stock fell 6% to $2.03 on volume of less than 15,000, according to Nasdaq.com. The shares are down more than 50% in the past year, and have surrendered more than 70% of their value since hitting a 52-week high of $7.15 on Dec. 15.

Another stock attracting interest in the extended session was CalAmp ( CAMP), which tacked on more than 10% after the wireless applications company beat Wall Street expectations with its fiscal second-quarter adjusted profit of $3 million, or 11 cents a share, on revenue of $33.8 million and gave an above-consensus outlook.
