Check out which companies are making headlines before the bell:

Constellation also raised its full-year forecast thanks to a strong beer business, although the numbers are still somewhat below Street estimates.
Yum Brands — The restaurant operator missed estimates by seven cents with adjusted quarterly profit of $1 per share. Revenue also came in below forecasts, and Yum's sales in the key China market were up a less-than-expected 2 percent. The parent of KFC, Taco Bell, and Pizza Hut also cut its full-year forecast, although it did release some positive news in the form of a 12 percent dividend increase.
