The merger saga of XM Satellite Radio (NASDAQ: XMSR) and Sirius Satellite Radio (NASDAQ: SIRI) has gone on for so long that yesterday's FCC approval was almost a letdown. The companies have lost hundreds of millions of dollars over the year-and-and half since the marriage was first proposed.

The green light comes with some draconian conditions. According to The Wall Street Journal (subscription required), "As part of the deal, the companies have agreed to a three-year price cap as well as promising to bring interoperable radios to the market within a year." The price cap arrangement could hardly be worse for the new operation. Each company still bleeds red ink and has over $1 billion in debt.

The ability to raise prices to consumers could be the key to the survival of satellite radio. The industry's major source of subscribers is new car sales. Those may not recover for two years. The combined company will have close to $2.5 billion in debt, and may have to raise more money. In the current environment, that will be hard. Depending on how the capital comes in, current common shareholders could be diluted.

The news of the approval should be accompanied with some joy, but, it won't be. That may be why the shares in both companies trade so low.
