It's certainly the trend in distribution sales these days for large holding compnies to gobble up smaller "mom & pop" distributors. The owners of my former employer couldn't accept the terms offered by a larger company, but eventually wound up going out of business (some years after I left). Ironically, the larger distributor has since been bought by an even larger company!
I wonder if and when the same trend may get started among independent integrators. Hmmm, maybe I should talk with a venture capital firm to back me in buying up every small integrator I can find. Anybody care to join me? We'll find a deep-pockets venture capitalist, spend the next few years gobbling up small engineering firms, give ourselves generous stock options and become instant billionaires at the IPO.
