A revenue boost, attributable to swift sales of host bus adapters, switches and silicon, kept the data storage supplier QLogic ( QLGC) roughly in line with Wall Street sales estimates for the third quarter. On Tuesday, the Aliso Viejo, Calif.-based company posted revenue of $157.6 million, about flat with Thomson First Call estimates of $158.3 million and a 22% spike year over year from $129.2 million in sales. But profit for the quarter ended Dec. 31 decreased 79% to $35.5 million, or 22 cents a share, from $166.2 million, or $1.02 a share, a year ago. Last year's third quarter included a profit of $130 million from a sale of operations; without the gain, the company would have earned 19 cents a share from continuing operations. After hours, investors recently sent shares down 2.7%, or 54 cents, to $19.58. Excluding items, income from continuing operations for the third quarter was $44.9 million, or 28 cents a share, vs. 19 cents a share a year ago. On that basis, the company edged out the consensus estimate of 26 cents a share. Shares of QLogic closed the regular session up 23 cents.
