Shut out by the economy

Remember Circuit City? Linens 'n Things? Sharper Image? KB Toys?

They're gone, all gone, and here are a few companies that might be next, according to Moody's Investors Service:

Claire's Stores. (Privately owned; about 18,000 employees.) Leon Black's once-renowned private-equity firm, the Apollo Group, paid $3.1 billion for this trendy teen-focused accessory store in 2007, when buyout funds were bulging. But cash flow has been negative for much of the past year and analysts believe Claire's is close to defaulting on its debt. A horrible retail outlook for 2009 offers no relief, suggesting Claire's could follow Linens 'n Things - another Apollo purchase - and declare Chapter 11, possibly shuttering all of its 3,000-plus stores.

Six Flags. (SIX; about 30,000 employees; stock down 84%). This theme-park operator has been losing money for several years, and selling off properties to try to pay down debt and get back into the black. But the ride may end prematurely. Moody's expects cash flow to be negative in 2009, and if consumers aren't spending during the peak summer season, that could imperil the company's ability to pay debts coming due later this year and in 2010.

Blockbuster. (BBI; about 60,000 employees; stock down 57%). The video-rental chain has burned cash while trying to figure out how to maximize fees without alienating customers. Its operating income has started to improve just as consumers are cutting back, even on movies. Video stores in general are under pressure as they compete with cable and Internet operators offering the same titles. A key test of Blockbuster's viability will come when two credit lines expire in August. One possible outcome, according to Valueline, is that investors take the company private and then go public again when market conditions are better.

Krispy Kreme. (KKD; about 4,000 employees; stock down 50%). The donuts might be good, but Krispy Kreme overestimated Americans' appetite - and that's saying something. This chain overexpanded during the donut heyday of the 1990s - taking on a lot of debt - and now requires high volumes to meet expenses and interest payments. The company has cut costs and closed underperforming stores, but still hasn't earned an operating profit in three years. And now that consumers are cutting back on everything, such improvements may fail to offset top-line declines, leading Krispy Kreme to seek some kind of relief from lenders over the next year.

Sirius Satellite Radio. (SIRI - parent company; about 1,000 employees; stock down 96%). The music rocks, but satellite radio has yet to be profitable, and huge contracts for performers like Howard Stern are looking unsustainable. Sirius is one of two satellite-radio services owned by parent company Sirius XM, which was formed when Sirius and XM merged last year. So far, the merger hasn't generated the savings needed to make the company profitable, and Moody's thinks there's a "high likelihood" that Sirius will fail to repay or refinance its debt in 2009. One outcome could be a takeover, at distressed prices, by other firms active in the satellite business.
