Aviza Technology ( AVZA) stock soared nearly 24% in extended trading Thursday after the California-based company more than doubled its sales and swung to a profit for the quarter ended Dec. 29. The maker of semiconductor capital equipment posted earnings of $1.1 million, or 7 cents a share, on revenue of $62.2 million. That compares with a loss of $4.6 million, or $1.25 a share, on $28.9 million in revenue a year ago. Shares were adding $1.06 to $5.50. Secure Computing ( SCUR) said fourth-quarter earnings totaled $5.3 million on a non-GAAP basis, or 7 cents a share, handily beating Street estimates that called for break-even, according to Thomson Financial. The San Jose, Calif., maker of network-security products took in $51.6 million revenue, falling just below the $55.8 million consensus. Last year, earnings were $6.7 million, or 17 cents a share, on sales of $30.2 million. In the current quarter, the company expects to make between $2 million and $3 million on a non-GAAP basis, or 3 cents to 4 cents a share -- at least a penny above the mean target. Shares were up $1.29, or 19.1%, to $8.04. Intuitive Surgical ( ISRG) shares were leaping after the Sunnyvale, Calif., surgical-equipment maker's plunging profits comfortably topped Wall Street expectations. The company earned $23.6 million, or 62 cents a share, on revenue that climbed 56% to $112.6 million year over year. Last year, it had a profit of $49.5 million, or $1.31 a share. Analysts were looking for 51 cents a share on revenue of $105 million. Shares were gaining $16.18, or 16.3%, to $115.50.
Sigmatel ( SGTL) plunged after it swung to a fourth-quarter and full-year loss. Excluding items, the Austin, Texas-based semiconductor company lost $8.8 million for the quarter, or 25 cents a share, compared with $6 million in profit, or 16 cents a share, a year ago. Full-year losses totaled $44.4 million, or $1.26 a share, down from an upside of $49.2 million, or $1.30 a share, in 2005. Both bottom lines beat Wall Street estimates, which had pegged per-share losses at 32 cents for the quarter and $1.34 for the year. Still, shares were trading down 51 cents, or 13.1%, to $3.39. Tumbleweed Communications ( TMWD) was down sharply on disappointing fourth-quarter earnings. The Redwood City, Calif., Internet-software developer made only $242,000, excluding items, or break-even, compared with a year-ago loss of $549,000, or a penny a share. Analysts were looking for a penny-a-share profit. Revenue was up 11% to $16.7 million, beating the $15 million consensus. But shares were losing 30 cents, or 9.2%, to $2.98.
