When I saw this announcement, the one question I had was whether the combined company, given the market share it would have, would run afoul of anti-trust laws. I am not the only one who thought that, as I saw a tweet or two to that effect and received a message from a friend (who can identify him/herself is s/he wants in the comment section) asking the same thing.
My initial reaction was that this might be a problem. But then three things happened:
1. Jason Sandquist correctly (and indirectly) reminded me that in many markets (including the small market where I live), the good old MLS is still king. The commercial service providers are big on the national level but they are not alone for information.
2. I saw in the press release the law firms working on the merger: Simpson Thacher for CoStar and Davis Polk for LoopNet. No slouches they -- two of the preeminent M&A law firms out there, with armies of folks able to argue that this deal is okay. (The business advisers were JP Morgan and Evercore Partners, respectively.)
3. Finally, this little wire gem on termination fees: if LoopNet tanks the deal it pays a 3% fee, or $25.8 million. If the deal tanks for anti-trust reasons, then CoStar pays LoopNet a 6% fee, of $51.6 million. I don't know what is typical in the business, not being an M&A guy, but I believe the proposed antitrust termination fee for the NASDAQ offer to buy the NYSE is just over 3%. So a 6% fee to me means someone must be confident it passes muster.
We will all keep an eye on this one, I'm sure.
