The CEOs of Berkshire Hathaway’s four largest holdings praised Warren Buffett’s vision, and authenticity this weekend during an interview with CNBC’s Becky Quick at the company’s annual shareowners meeting in Omaha, Neb.

Coca-Cola Chairman and CEO Muhtar Kent joined IBM Chair and CEO Ginni Rometty, American Express Chairman and CEO Ken Chenault, and Wells Fargo Chairman and CEO John Stumpf for a 30-minute Squawk Box segment. The four blue-chip companies represent more than 60 percent of Berkshire Hathaway’s investment portfolio.

Buffett is Coke’s largest shareowner. He served on the company’s board for 17 years, from 1989 to 2006, and just last week made a surprise appearance at the company’s annual meeting in Atlanta to share his thoughts on Coke’s growth prospects, consumer trends and the rebounding U.S. economy.

“There is no one else I know who’s as keen an observer of trends, of people or of countries,” Kent said. “He has this unique ability to follow consumers and where they want to go."

Kent also applauded famously folksy investor’s signature “fusion of humor and humility”, which was on display at Coke’s annual meeting during a prerecorded video of Buffett playing a ukulele and singing “I’d Like to Buy the World a Coke" as a tribute to the 100-year-old Coca-Cola bottle.

“Everyone loves him,” Kent added. “He’s able to simplify complex matters in just a few words, and I think that’s an incredible asset.”
