Check out which companies are making headlines before the bell:
Krispy Kreme –The doughnut chain reported third quarter profit of 16 cents per share, excluding certain items, one cent above estimates. However, revenue was slightly short of estimates and the company gave fiscal 2015 EPS guidance of 71 to 76 cents per share, below the 77 cent consensus estimate. Krispy Kreme said international same store sales will likely decline despite growth domestically.
Micron – Needham began coverage of the chipmaker with a "buy" rating, despite admitting to being "late to the party" on the stock. The firm cites multiple opportunities for expansion.
Yum Brands–The parent of Pizza Hut, KFC and Taco Bell reported flat November sales in China, its biggest market, disappointing investors who had hoped to see growth. China accounts for more than 50 percent of the restaurant chain's operating profit.
Apple– The iPhone maker has bought social analytics firm Topsy, with the price reportedly over $200 million. Apple wouldn't comment on why it bought the company, which analyzes Twitter data to determine current sentiment on a variety of topics. Separately, Fortune reports China Mobile is taking preorders for the iPhone 5S and 5C. China Mobile is the world's largest mobile phone operator, but has not to date carried Apple's iPhone.
CVS Caremark– The company's Caremark unit will pay $4.25 million to settle claims that it failed to reimburse Medicaid for prescription drug costs that should have been paid for by private health plans.
Thor Industries – Thor reported fiscal first quarter profit of 68 cents per share, two cents below estimates, with revenue also short of consensus. The maker of recreational vehicles did see profit rise 33 percent from a year earlier.
Tesla – Tesla said German regulators reviewed recent Model S fires in the U.S. and decided that no measures were necessary. U.S. regulator NHTSA is currently in the midst of its own probe of those fires. Separately, Morgan Stanley named the stock a "top pick", saying the recent pullback is a buying opportunity.
BP – The UK oil giant won an appeals court decision, as it seeks to avoid payment on certain 2010 Gulf oil spill claims that it said were not traceable to that event. The ruling said a lower court had erred in approving the payout formula for spill claims.
