Texas Monthly:

Monday, April 10, was going to be a big day for John Mackey, but he had no idea how big it would turn out to be. The co-founder, CEO, and spirit animal of Austin-based Whole Foods Market was flying to New York to launch a tour to promote the publication of his second book, The Whole Foods Diet (summary: Go vegan, or mostly vegan).

And:

As he stepped off the American Airlines flight at JFK (Whole Foods doesn’t own a jet, and Mackey flies coach), his phone lit up with urgent text messages and voice mails. A hedge fund in New York called Jana Partners had snatched up almost 9 percent of Whole Foods’ stock and announced that it would pressure the company to either overhaul its business or sell itself—perhaps to another grocery giant, such as Kroger, or to a less traditional player, such as Amazon. Mackey and other leaders might have to be replaced. A media frenzy ensued, and the PR team who had carefully staged what should have been a traveling celebration of their boss as a thought leader shifted into immediate crisis mode.

“From that moment on, I was drowning in it,” Mackey says.

Mackey built Whole Foods from scratch, instilled a set of principal beliefs, built a management team that followed those beliefs. Whole Foods continued to grow, and then the hedge fund folks smelled the deal that was possible.

Fascinating, horrifying (depending which side of the fence you’re on), and a tale as old as Wall Street.
