Coca-Cola (KO) CEO James Quincey is no stranger to chatting it up with Warren Buffett.

Berkshire Hathaway (BRK.A) is a long-time shareholder of Coke, in large part because of the wide moat around its business. The fact Buffett loves drinking Cherry Coke helps, too.

Buffett recently disclosed that Berkshire still owns 400 million shares of Coke. Berkshire is Coke's largest shareholder.

Asked by TheStreet what he has learned from Buffett in terms of leadership, Quincey said it's a litany of things.

"He has literally written several books on leadership and investing, and I think they are always very pragmatic, and commonsense rounded in the fundamentals of business," Quincey said. "I think they are very profound."

So far, Quincey has given Buffett a few reasons to think he is a profound leader, too. 

Coke's fourth-quarter earnings beat Wall Street's profit forecasts by 1 cent, fueled by momentum in the water and tea categories. Profit also was boosted by Coca-Cola's cost-cutting efforts and move to divest its bottling operations.

Organic sales increased 6% from the prior year. For 2018, Coke said it sees organic revenue rising 4%, with earnings gaining as much as 10%.
