Satellite radio company Sirius XM continues discussions with Howard Stern about a potential extension of his contract, which expires at the end of the year, CEO Mel Karmazin said Thursday (Nov. 4).

"We do not have any updates today," he said on his company's quarterly earnings call. He had previously said he was hoping to have more insight into Stern's future by the call.

Sirius said Thursday it swung to a third-quarter profit as it continued to grow revenue, while controlling costs and didn't have a big loss for debt extinguishment as it did in the year-ago period.

The quarterly profit of $67.6 million compared to a year-ago loss of $151.5 million. Revenue rose 16% to $717.5 million from $618.7 million.

The company said its adjusted revenue set a record, and it raised its full-year financial expectations after previously boosting its subscriber guidance.

Sirius now projects that adjusted revenue for 2010 will exceed $2.8 billion. It expects to end the year with approximately 20.1 million subscribers.

"We continued our positive momentum in the third quarter, improved our churn and conversion rates and attained a record high subscriber count," said Karmazin.

While he didn't comment before his earnings conference call on the state of contract talks with Stern, Karmazin also said in a statement: "We will continue to increase and diversify our content offerings with new shows, new celebrity hosts and specialty programming with fantastic appeal to new and existing subscribers."

Sirius ended the third quarter with 19,862,175 subscribers with net user additions of 334,727 in the latest period.
