Some companies are in growth businesses; the stock market, as a rule, tends to love them. Other companies are in an inexorable secular decline; they tend to get punished by equity investors. There's a good reason for that: stock-market investors are looking for stocks which go up over time, rather than stocks which are going to zero while paying out as much in dividends as they can along the way.
If you want an example of a business which is in a certain secular decline, it's hard to come up with a better one than AOL's hugely profitable dial-up business. And so it makes a lot of sense that, as Claire Atkinson reports today, AOL is looking at the idea of going private -- perhaps with a sale to KKR. This is not a particularly revolutionary idea: Jonathan Berr has pushed it, and Bloomberg called it AOL's "last, best hope". AOL is on the record as having hired the most high-powered M&A advisors in the world; they're no idiots, and only idiots wouldn't look at a buy-out option for a company trading at a significant discount to its book value.
If I were a potential private-equity buyer, though, I'd do a sum-of-the-parts analysis and rapidly come to the conclusion that Tim Armstrong's strategy is too much risk for too little potential reward. Take AOL, and sell off the non-core assets -- things like Moviefone, MapQuest, AIM, and Advertising.com. What's left? The AOL/HuffPo traffic-and-content monster, on the one hand, and the dial-up business, on the other. Armstrong's idea is that you use the cashflows from the latter to beef up the former, so that when the dial-up revenue eventually disappears, the dial-up caterpillar has transformed itself into a glorious web-publishing butterfly. (Sorry, MSN.)
