Sirius XM Radio Inc.: Miller Tabak equity analyst David Joyce reiterated a buy rating on shares of Sirius XM Radio Inc. (SIRI) on Sept. 3, with a short-term price target of $1.25 and a long-term target of $1.45.

In a note, Joyce said he was lowering estimates on Sirius, the only U.S. satellite radio broadcaster, to reflect higher estimates for customer turnover, or churn, in the second half of 2010 after a spike in net subscribers added in the second quarter.

Joyce lowered his estimates for free cash flow for the third quarter to $41 million from $56 million, and for 2010 to $143 million from $192 million.
