I spent a week at a generational wealth transfer seminar with Chick-fil-A's CEO. Selling, I can guarantee you is not their plan. Another point to consider is that a large part of the moat is the religious culture of Chick-fil-A. That believe or culture can be attacked. Remember Pampered Chef? Their sales dropped bad when the anti-abortion believers organized a boycott against Pampered.It was based on the contribution program BRK had at the time where individual shareholders could identify donees for BRK to contribute to based on their ownership. Chick-fil-A CEO, Dan Cathy has been outspoken about same-sex marriages. Caused a problem for a while as they entered the California market. Berkshire acquiring Chick-fil-A? I see a moat, but a weak layer of clay that holds the water in the moat. A strong political or religious belief becomes an obvious target for protesters that can spread to other units of Berkshire. Striking trade unions recruit other trade unions to join their cause. Leaving on a happy note, maybe they change the name to Berk-a-Chick and sales zoom!
