Tuesday's Tech Winners & Losers

Shares of Celestica(CLS Quote) were among technology's losers Tuesday, falling 12% after the electronics manufacturing services company slashed its fourth-quarter projections.

The company now sees adjusted earnings break even to 6 cents a share, compared with an October forecast of 15 cents to 23 cents. Celestica predicts revenue of $2.2 billion to $2.25 billion, down from its earlier view of $2.25 billion to $2.45 billion. Analysts polled by Thomson First Call projected earnings of 19 cents a share on revenue of $2.36 billion.

Celestica attributed the guidance cut to recent demand reductions from several customers. The revised guidance includes a charge of 8 cents to 12 cents a share related to an increase in inventory provisions at its Monterrey, Mexico, facility. Shares were trading down $1.12 to $8.25.

Shares of Endwave(ENWV Quote) sank 14% after the wireless-technology company cut its 2006 revenue forecast. For the fourth quarter, the company sees revenue of $10 million to $12 million, implying full-year revenue growth of 20% to 25%. In October, the company projected revenue growth of 35%.

"As discussed on our third-quarter conference call, we anticipated a potential decline in revenues during the fourth quarter due to the impending merger of the network businesses of Nokia and Siemens and a resulting inventory reduction by the companies," Endwave said in a press release. "However, Nokia management has recently informed us that their pre-merger inventory reduction, and consequently the contraction in our revenues, will be larger than they had originally projected." Shares of Endwave were down $1.80 to $10.99.
