The server and software vendor reported a preliminary loss in the range of US$0.25 and $0.35 per share, including a charge of about $60 million associated with the restructuring that Sun announced Aug. 1. Not counting that charge or other one-time items, the company said it would post a loss of between $0.02 and $0.12 per share.

Revenue for the quarter will come in between $2.95 billion and $3.05 billion, down from $3.22 billion in the first quarter of fiscal 2008, Sun said. The company plans to release its complete first-quarter results on Oct. 30.

Financial analysts surveyed by Thomson Financial had expected a loss of $0.01 on revenue of $3.14 billion.

"Sun and its customers are seeing the impact of a changing economy," CEO Jonathan Schwartz said in a prepared statement. The company is a major supplier of IT systems to financial services firms, which have been hammered in recent weeks by falling stock prices and the credit crisis.

As it released the preliminary results, Sun also said that because of several factors, including the poor economic environment, it may have to take a charge for goodwill impairment related to some of its businesses.
