Its stock price fell by more than half and activist investors like Jana Partners began to assert ownership rights, much to the dismay of co-founder and co-CEO John Mackey, the only original founder still with the company. Though he admitted the company had changes to make, Mackey was against selling Whole Foods.

Mackey, whose salary as CEO has only been $1 a year since 2006, is making $8 million from the sale of Whole Foods to Amazon, surprisingly little for a company sale of this size. He owns 980,000 shares of Whole Foods stock and the sale is based on a share price of $42. Jana Partners’ profit is reportedly $300 million.

It all started on a vegetarian co-op in Austin

Mackey, now 63, grew up eating cocoa puffs for breakfast, a hamburger for lunch and boxed macaroni and cheese for dinner, he tells host Guy Raz on a recent episode of the NPR show, “How I Built This.” He didn’t start to understand that there was a value in eating a vegetable-based, healthy diet until he moved into a vegetarian co-op, when he was 23, which, at the time, he thought of as an adventure.

At the vegetarian co-op, Mackey, who had dropped out of college because he found the required classes boring, became the buyer for the group. He was fascinated with the potential of healthy eating.

Without a diploma but newly inspired by the power of organic eating, Mackey and his then girlfriend, Renee Lawson Hardy, decided to go out on their own and open a natural grocery store. They set out to raise $50,000, but could only muster $45,000. In 1978, they opened shop on the first floor of an old house in Austin with a cafe on the second floor. The couple lived on the third floor. It was called SaferWay, it didn’t sell meat or anything with sugar and it primarily served Austin hippies.

Two years later, Mackey and Hardy approached another local natural grocery store, Clarksville Natural Grocery, owned by Craig Weller and Mark Skiles, about joining forces. The four went into business together to open the first Whole Foods Market in 1980. In an effort to expand the clientele, the four started selling meat, beer and wine.

From the first day they opened, Whole Foods Market was a success. “People were so excited about this first store. It was amazing, and we didn’t do any advertising. We just opened the doors,” says Mackey on “How I Built This.” “The word of mouth was incredible. The whole Austin counter culture hippie community knew about it immediately.”

Near-death experience

When Mackey looked to rent the space that would become the first Whole Foods Market, the landlord mentioned it was in a 100-year-flood zone, meaning that once every hundred years the area would flood. Mackey, enthusiastic, young and eager to grow, didn’t flinch. He was willing to take the risk. It turned out to be a losing bet.

In the Spring of 1981, that 100-year flood landed. The store was drowned, sewage forced out of pipes, inventory ruined and looters came and trashed the store. Mackey remembers wading through the dark waters to get whatever cash they had left in the store safe.

They didn’t have flood insurance. “We thought we were pretty much out of business,” says Mackey. “By all rights, Whole Foods should have died through that flood. We had to rebuild the store and it was going to cost a lot of money to do that and we just didn’t have the money, so I thought, we all thought, we were finished.”

The Austin community stepped up to save the business. Customers pitched in to help with the cleanup effort, investors put in more money, banks extended credit lines and team members (employees) worked for free to get the store back open.

“We were really united around that near death experience,” Mackey says. When they got the store re-opened, Mackey was determined to expand. “I wanted to open a second store after the flood. It was like, we can’t put all of our eggs in a basket that might float down the river.”

In 1988, when Mackey approached venture capitalists for the money to expand in a significant way, he was repeatedly rejected. He remembers one VC telling him the market was too niche: “You know, John, I see you have got a pretty good business her, but it looks to me — I looked at all the stores — like you are a just a bunch of hippies and you are just selling food to other hippies and I don’t think that is a very big market,” he told Mackey. A decade later, that same venture capitalist told Mackey not investing in Whole Foods was the worst decision he’d ever made.

Mackey did raise venture money though: Whole Foods sold 34 percent of the business for an $8.5 million valuation, which at the time was about 15 to 20 percent of sales, says Mackey on “How I Built This.” Hungry for cash to grow further but uninterested in handing over more of his company to venture capitalists, Mackey took Whole Foods public in 1992 and raised $28 million valuing the company at $100 million. With the cash, Whole Foods scooped up a slew of other natural food markets around the country.

Whole Foods’ growth continued as eating healthy became increasingly mainstream. In 2016, there were more than 460 stores in the United States, the company did $16 billion in sales and had 87,000 employees, according to a recent financial disclosure.

Of course, that growth didn’t come without controversy. In 2015, the store was taken to task for systematically over-weighing and overcharging certain food items. Whole Foods denied that these errors were anything other than inadvertent.

“There will be no one that ever loves Whole Foods Market as much as I love it”

Unable to thwart the pressure from investors to sell the struggling chain, Mackey is caught between his ideals and a need to keep afloat the business that he created.

“There is no point in business where you can say, ‘At last, I have arrived.’ What makes business so amazing is, what makes capitalism so dynamic is that in fact, if you are successful, people copy you. And that’s what has happened with Whole Foods. A lot of people have copied us. That helps keep your edge,” says Mackey.

Today, Mackey still lives in Austin and purposefully drives by the location of the first store, which is now a school. He thinks of the past, but he also understands that to stay in business means evolution.

“There will be no one that ever loves Whole Foods Market as much as I love it,” says Mackey. “But building a business is a little bit like having children and watching the children grow up … you hope your child is healthy, you hope your child is happy and you hope your child has integrity and does the right thing. And I think it is important to have a good founder and entrepreneur but the great businesses continue to live on after the founder moves. I certainly hope Whole Foods is in that space.”
