NEW YORK: US satellite radio giant Sirius says it expects to end the year with between 5.9 million and 6.1m subscribers. Less than a month ago, the broadcaster claimed to be on track for 6.3 million subscribers.

Sirius says slow recent sales have forced it to trim its figures. Last year, the company added 1.1m subscribers in the fourth quarter in anticipation of shock jock Howard Stern's January 2006 debut.

Arch rival XM Satellite Radio has revised down its subscriber forecast several times this year, most recently in November, when it said it would end 2006 with between 7.7m and 7.9m subscribers, down from 9m it expected at the start of the year.

Comments an XM spokesman: "We concur with Sirius's assessment of a softness in the retail market."
