xm-logo-black.gif XM Satellite Radio has scheduled a conference call for Monday, May 12, 2008, at 10:00 a.m. ET to announce and discuss its first quarter 2008 financial results. Prior to the call, XM Radio’s first quarter 2008 results will be posted to the Company’s Web site and released to PR Newswire and First Call. The company, like irius is waiting until the last possible day to announce earnings. With respect to the timing of the call, it makes sense for XM to go first, while Sirius will follow suit a few hours later. This is a rare occasion where investors will have data and metrics from both companies on the same day.
