Sirius Satellite Radio Inc. (NASDAQ: SIRI) saw a quarterly subscriber increase of more than 50% as the satellite radio company reported a smaller-than-expected Q3 loss this morning. Still ahead is Sirius' planned merger with competitor XM Satellite Radio (NASDAQ: XMSR), which is still on the regulatory burner as this is being written.

Sirius did see a Q3 loss of $120.1 million ($0.08 per share) compared to a year-ago loss of nearly $163 million ($0.12 per share), but revenues did rise 45% to $241.8 million for the quarter, compared to 2006's $167.1 million. The results barely fell short of the market's expectation of $244.3 million. Putting it another way, Sirius pretty much hit analyst expectations. How the estimates can nail such a specific figure is anyone's guess.

Sirius had a devil of a time in the quarter when it can to subscribers, as it added almost 525,000 new ones to its ranks for the July-September period alone. This is the unreal part: Sirius ended the Q3 period with right at 7.7 million subscribers -- a 50% increase than a year ago.

In other words, Sirius added half its customer base just in the last year alone. Now, that's growth (in subscribers, not profit). XM Radio still has more subscribers at 8.6 million, but Sirius may indeed have more before the merger is finalized and complete if it continues growing at the rate it has been in the last few quarters.

Sirius Satellite Radio, Inc. (NASDAQ: SIRI) will be up bright and early today, as the company will be reporting its Q2 financials in a live webcast here in a few moments at 8 a.m. EST.

Of particular note recently has been CEO Mel Karmazin's announcement that a cheaper "a la carte" option would be available to customers of a combined Sirius / XM Satellite Radio Holding, Inc. (NASDAQ: XMSR) -- something like $6.95 per month -- which has probably gone a long way toward appeasing regulators who still continue to believe that a "monopoly" would be in place with a single national satellite radio operator.

Sirius is expected to report a loss of 10 cents per share on revenue of $228.3 million for Sirius' Q2 period, down from a $0.17 loss for the year-ago quarter. If the merger (buyout, actually) is approved between XM and Sirius soon, this may be one of the last quarters where a loss is expected and delivered. If you're holding onto SIRI, are you ready for this? Thought so. Remember to use the "Refresh" key to ensure you catch all the updates as they happen below. All times below are in EST.
