Initial reports are just coming in off of the news wire, but apparently XM has ended its marketing pact with Starbucks.

It looks like XM is going to be selling 1.85 million shares, or approximately 22 million dollars worth of stock for Starbucks. Stock prices plummeted in early trading, dropping at one point over 12%.

Why would XM be canceling a marketing pact with one of the largest brand names out there today? We will wait for the official filing of course, but this does not look very promising...
