"When you think of a business that's easy to understand, with favorable long-term economics, and able and trustworthy management -- you think of Wrigley," Buffett said in a statement issued by Wrigley. "Bringing together these iconic, world-class companies combines Wrigley's strengths with the deep resources and proven brand-building savvy of Mars and will result in a powerful force for innovation and growth in the global confectionery marketplace."

Wrigley shares soared more than 23% after the opening bell to $77.

Mars, which makes candy brands such as Snickers, M&M's and Dove, will add Wrigley's Doublemint, Spearmint and Juicy Fruit gums and Lifesavers to its product mix.

"The strong cultural heritage of two legendary American companies with a shared commitment to innovation, quality and best-in-class global brands provides a great basis for this combination," Mars Global President Paul Michaels said in a company statement. "We are looking forward to continuing on our path of growth by jointly developing those values even further."
