Sirius XM Radio's subscriber additions fell short of expectations, which sent the satcaster's share price down 8% on Tuesday, reports Reuters. The company also had a harder time getting customers to commit to its service once its promotions end. It acquires most of its new subscribers by offering free trials when people buy new cars. The conversion rate of trial subscribers who became full paying subscribers fell to 44.4% in the third quarter, down from 48.1% a year earlier. The company plans to increase the base price of its packages, Sirius and XM Select to $14.49 from $12.95 a month starting Jan. 1.
