I don't get why a company gets bought out, then shortly afterwards gets shut down. Often the one thing that gives the company value is what gets shut down. Are the purchasing companies not aware that their purchase isn't of value after the fact?
What is being purchased in a buyout doesn't have to be what was profitable to the original company. Consider the classic farm example.
A farmer is making a living with a decent $10,000 yearly profit on his 100 acres. He provides the local community with fresh produce, pays his taxes, and is putting away a decent amount into his savings. By all accounts, his business is doing well. He then receives an offer to buy his farm, as-is, for $3,000,000. The farm is sold.
However, the company that purchased the farm lets the equipment rust, the fields go fallow, and the barn collapse. Why would they purchase a profitable farm if all they were going to do is let weeds grow and shut it down. The answer comes later, when 400 future housing plots are identified for sale at $400,000 each. Turns out, while the farm was profitable, the land was worth MUCH more as a housing development. Rather than earn $10,000/year in profit through hard work, the purchasing company turned a $3,000,000 purchase into a $160,000,000 real estate deal.
The farm could have continued, as it was making a profit, but it wasn't making nearly as much of a profit as it could have made. (not that I like farm's beind developed, but I think this is a good example to demonstrate why seemingly profitable enterprises get shut down after a buyout)
