Dow component Kraft Foods beat profit estimates in the second quarter, raised its guidance and announced it will split in two. Two of the company's largest shareholders — Nelson Peltz and Warren Buffett — later endorsed the split.

Kraft's profit per share was 62 cents compared with 58 cents forecast by analysts while net revenue was up 13.3 percent to $13.9 billion from $13.15 billion expected by analysts surveyed by Reuters.
