The last takeover target we're looking at is toolmaker Snap-On ( SNA). Snap-On is having a good 2012. So far this year, shares of the firm have rallied more than 44%. But there's still considerable value that can still be unlocked from shares right now, and other companies know it. Snap-On's target market is the professionals. It sells its tools and diagnostic equipment primarily to techs who work on cars, trucks, planes or other machines. That pro image carries over to the retail market too, though. So-called "prosumers" want to use the same tools that the pros use, and ultimately Snap-On has a big untapped market to in the retail space. Despite some modest advertising to consumers, the firm's bread and butter remains the professional market. A fleet of 3,200 franchised vans sell and deliver tools directly to repair shops across the U.S. That control of the product from manufacture to delivery gives SNA precision control over its costs that outsourcing rivals don't have. While the firm's balance sheet is more leveraged than most of the other names on this list, Snap-On's still in decent financial shape, especially when compared to peers. A potential suitor could unlock significant value in making a bigger retail presence from what's already a valuable brand.
