I've seen the same thing happen several times over the last 10 or so years here in Sacramento. A local company that everyone loves to deal with just shuts down. That doesn't happen by accident. First, the owners have to decide that no matter which way they work the numbers, there's going to be more money going out every year than coming in. Then you have to assume that the employees must have considered an employee buyout, because after all, the alternative is losing their jobs. The employees must have also decided that there was no way they could pull it off and still make a living wage. If the insiders can't figure out any way to make it work, then it's got to be tough for a new owner to make it work. You would think that if a business was as popular as some of the local businesses I'm thinking of, somebody or some group of employees would buy the business and keep it going. The fact that it hasn't happened means that popularity with the public is not the same thing as making money, I guess.
It would probably make sense for someone to buy some of their equipment and continue some of Martin's product line as an expansion of whatever their own product line is.
