The owner of Budweiser and Corona is planning the largest IPO of 2019. Meet the company's notoriously private CEO, who only has one hobby and doesn't like company perks

Brito earned a bachelor's degree from Universidad do Rio de Janeiro, according to Bloomberg. Before going on to get his masters at Stanford, he was an executive at Shell. Brito convinced former Brazil tennis star Jorge Paulo Lemann to fund his time at Stanford, according to the Financial Times.

He has since returned to Stanford to speak with current MBA students, NBC News reported.

The AB InBev leader rarely gives interviews and not much is known about his personal life.

NBC News reported that the company even declined to confirm that Brito is married and has four children, saying "We don't give details on his private life."

"My life is the company and my family," Brito told the Financial Times.

He also said his only pastime is taking a daily 30-minute walk on a treadmill.

Brito first came to AmBev in 1989 and worked in finance, operations, and sales before becoming its chief executive in 2004.

InBev was formed in 2004, and Brito became the CEO of the company in 2005. In 2008, InBev acquired Anheuser-Busch, and Brito became the CEO of the larger group, Anheuser-Busch InBev.

Brito was paid €1.48m ($1.6 million) by AB InBev in 2017, according to the Financial Times, in addition to his ownership of an options grant that was worth €250m (about $469 million in today's dollars) at the time.

AB InBev makes Budweiser, Bud Light, Corona, Stella Artois, and numerous other beers, according to its website.

Brito asks that all employees' performance be monitored constantly and formally reviewed each year, according to the Financial Times. He reportedly doesn't hesitate to let go of employees who aren't up to par if they don't improve in six to nine months.

"Great people attract more great people," Brito said, according to the BBC. "That's obvious, but the opposite is even more dangerous. Mediocre people attract more of the same."

Brito and CFO Felipe Dutra lost their annual bonuses in 2017 after the brewer saw its first decline in core earnings since its formation, according to the St. Louis Business Journal.

Brito doesn't use a company car to get around or have a dedicated desk at AB InBev's headquarters, NBC News reported. According to the Financial Times, he asks to be called "Brito," not "Mr. Brito."

He doesn't even take advantage of one the more basic perks of running the world's largest brewer: free beer.

"I don't want the company to give me free beer," Brito told Stanford MBA students in 2008, according to NBC News. "I can buy my own beer."
