Revenues for XM Satellite Radio jumped 82 percent to $227.9 million in the 2006 second quarter, but the satellite operator’s loss increased to $231.7 million, XM Satellite Radio Holdings Inc. announced July 27.

In the same period in 2005, XM lost $148.8 million on revenues of $125.4 million. The second quarter loss includes $105 million in charges for restructuring its debt, XM said.

XM credited its revenue gains to a 56 percent increase in subscriber growth and increases in average revenue per subscriber. XM added 926,000 subscribers during the quarter, which closed June 30, to raise its total subscriber count to 6.9 million. In the 2005 second quarter, XM added 398,000 subscribers to bring its total to 4.4 million.

Subscriber acquisition costs was $64 in the 2006 second quarter, compared to $50 in the 2005 second quarter. Cost per gross addition grew from $98 to $112 in the same period.

The satellite radio company also dropped its subscriber targets, cutting the number from an anticipated 8.2 million by the end of 2006 to 7.7 million due to “current marketplace dynamics and regulatory uncertainties concerning plug-and-play radios.” XM also said it would revisit that number at the end of the third quarter. In May, XM dropped its subscriber estimate from 9 million to 8.5 million.
