Tuesday's Tech Winners & Losers

Shares of Sanmina-SCI(SANM Quote) were among technology's losers Tuesday, slumping 15% after the electronics-manufacturing services company cut its third-quarter earnings and revenue projections.

For the period ended July 1, the company now sees adjusted earnings of 6 cents to 7 cents a share, down from an earlier forecast of 8 cents to 10 cents a share. The company projects revenue of $2.71 billion, at the low end of its previous guidance of $2.7 billion to $2.8 billion. Analysts polled by Thomson First Call project earnings of 9 cents a share on revenue of $2.75 billion. Sanmina blamed the shortfall on a less-favorable product mix, lower-than-expected profitability in its computing business and slower-than-anticipated improvement in its enclosure business.

"While we are disappointed that our financial results for the fiscal third quarter fell short of our expectations, we believe that we have taken the steps necessary to improve on our execution," Sanmina said. Shares were trading down 63 cents to $3.64.

Network Appliance(NTAP Quote) shares rose 2% after the maker of networking gear backed its first-quarter guidance. For the three months ending July 31, the company continues to forecast earnings of 23 cents to 24 cents a share, excluding stock-based compensation costs and amortization of intangible assets. Network Appliance sees sequential revenue growth of 2% to 4%. Analysts project earnings of 24 cents a share and revenue of $615.6 million, or sequential revenue growth of about 3%. Shares were trading up 57 cents to $27.66.

Shares of China TechFaith(CNTF Quote) plunged 24% after the handset-software company slashed its second-quarter earnings and revenue projections. The company expects to post earnings of $4 million, down substantially from its previous view of $8.5 million. The company now projects revenue of $22.5 million, below its earlier forecast of $24 million. Analysts project earnings of $8.5 million, or 19 cents a share, on revenue of $24.1 million.

"While we expected the transition period in our business would be confined to the first quarter, it extended into the second quarter," China TechFaith said. "We are now adding three to four months onto our internal forecasts to reflect the lengthier approval and testing process required by the international carriers for Smartphone and the required quality-testing process of the new international customers for the Handset Design projects." Shares were trading at $9.74, down $2.88.
