Intelsat Ltd. lost $325.3 million in 2005, compared to $38.7 million in 2004, due to higher operating expenses, Intelsat reported April 18. The satellite operator reported revenue growth of 12 percent to $1.2 billion in 2005.

Earnings before interest, taxes, depreciation and amortization (EBITDA) increased $79.7 million to $655.9 million, or 56 percent of revenue, for 2005. The increase was attributed to stronger revenues overall and the full year contributions of the Intelsat Americas assets and the IGen business.

At the end of 2005, Intelsat’s backlog stood at $3.8 billion.

Intelsat remains on track to complete its acquisition of Panamsat Corp. before the end of the third quarter, the company said.
