One eager reader of Warren Buffett's annual letter will probably be Coca-Cola (KO) CEO James Quincey.

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."

Watch what Quincey said about Coke's transformation below.
