Check out which companies are making headlines before the bell:
Burger King Worldwide–Burger King has finalized its deal to acquire Canada-based doughnut chain Tim Hortons. Warren Buffett's Berkshire Hathaway will make a $3 billion investment in the form of preferred shares, and sources tell CNBC's Andrew Ross Sorkin that Buffett's investment will actually not save in taxes. Those sources say the structure of the deal is more about getting it approved by Canadian regulators.
Best Buy–The electronics retailer earned 44 cents per share, excluding certain items, beating estimates by 13 cents. Revenue was slightly shy, however, and comparable store sales fell more than expected. Best Buy did benefit from cost reduction efforts, but CEO Hubert Joly said store traffic continues to decline.
DSW–The shoe retailer beat estimates by six cents with quarter profit of 38 cents per share, and saw revenue well above expectations as well.
Movado–The watch maker fell ten cents short of consensus with second quarter profit of 44 cents per share, with revenue also falling short. Movado does say it expects sales to accelerate in the second half of the year, and reaffirmed its full-year forecast.
