Check out which companies are making headlines before the bell:
General Mills — The cereal and food maker earned an adjusted 65 cents per share for its latest quarter, 3 cents above estimates, though revenue was slightly below forecasts. The results were hurt by the strong dollar and weaker U.S. sales.
Nike — The athletic footwear and apparel maker earned 55 cents per share for its latest quarter, 3 cents above estimates. However, revenue was short of expectations, putting the shares under pressure. Nike did chalk up a 12 percent gain in future orders compared to 2 percent a year earlier.
Krispy Kreme Doughnuts — Krispy Kreme beat estimates by a penny a share, with adjusted quarterly profit of 22 cents per share. The doughnut chain's revenue was shy of Street estimates, however, and it forecast full-year earnings below Street forecasts. Krispy Kreme's results in international markets weighed on its overall numbers, with same-store sales dropping 7 percent.
Red Hat — Red Hat reported adjusted quarterly earnings of 52 cents per share, 5 cents a share above estimates, while revenue for the Linux software provider also topped expectations. Red Hat's guidance for the full year also exceeded analysts' forecasts, thanks to increasing demand for its software and cloud services.
AutoZone — The auto parts retailer increased its stock buyback program by $750 million.
Merck — The drugmaker emerged victorious in a patent battle with Gilead Sciences, with a jury upholding a patent involving Gilead hepatitis C drugs. The jury in the case will now decide how much in damages to award to Merck.

The Federal Trade Commission is suing to block the deal, and the testimony appeared to support the regulators' case, according to observers.
United Continental — The airline should appoint one of its two new board members as chairman, according to hedge funds PAR Capital and Altimeter Capital. A Securities and Exchange Commission filing by the two asks that the appointment be made before shareholders vote on a slate of six other directors recently proposed by the funds.
