NEW YORK (Bloomberg) — Global Crossing Ltd., the fibre-optic network operator that survived one of the largest US corporate bankruptcies, posted a wider third-quarter loss on costs from its acquisition of Impsat Fiber Networks Inc.

The net loss expanded to $88 million from $50 million a year ago, and the Bermuda-based company didn't provide per- share figures in a statement today. Sales rose 27 percent to $594 million, in line with analysts' estimates.

Global Crossing expanded its network and added Latin American customers by buying Impsat in May. Chief executive officer John Legere had fired workers a quarter earlier to help reduce annual costs by $40 million starting in 2008.

Adjusted earnings before interest, taxes, depreciation and amortisation were $74 million, beating an estimate of $49 million from Janco Partners Inc. analyst Donna Jaegers in Greenwood Village, Colorado.

Analysts anticipated sales of $592.9 million, according to the average of three surveyed by Bloomberg.

The company maintained its full-year sales and earnings forecast. Global Crossing said sales will rise to $2.17 billion to $2.25 billion and adjusted EBITDA will increase to $165 million to $195 million.

Global Crossing, whose network transmits video feeds for CNBC Europe and connects defense contractor Northrop Grumman Corp.'s customers worldwide in simultaneous flight simulations, rose 30 cents to $20.48 in Nasdaq Stock Market trading on Monday. The stock had fallen 17 percent this year before yesterday.
