Rackable CEO Tom Barton said that the customer order delay that hurt third-quarter revenue, has been secured for the fourth quarter and was larger than expected. As a result of that order, as well as strong bookings momentum for the past 60 days, Barton said the company now expects to surpass its full year 2006 projections.

Rackable recorded a loss of $389,000, or one penny a share, in the three months ended Sept. 30, due to $3 million in charges for R&D and amortization of intangibles associated with its acquisition of

Excluding the charges, Rackable said it earned 19 cents a share, a penny shy of Wall Street expectations.

Looking ahead, Rackable projected $100 million to $110 million in fourth-quarter revenue, with EPS of 25 cents to 27 cents excluding certain charges. Analysts polled by Thomson Financial were looking for $94.3 million in fourth-quarter sales with 23 cents EPS.

"We are now actively supplying our products to 9 of the top 20 Internet sites and are on track to deploy to a 10th during the fourth quarter," said CEO Barton.

During the third quarter, Rackable said storage revenue accounted for 16% of total revenue, up from 8% in the year ago period.
