Check out which companies are making headlines before the bell:
CF Industries—The fertilizer maker will buy the European, North American, and global distribution businesses of Netherlands-based OCI. The deal is worth $6 billion, excluding assumed debt, and CF will become a subsidiary of a new holding company headquartered in the United Kingdom.
Coca-Cola Enterprises—CCE is combining with two other large Coca-Cola bottlers to form a new company called Coca-Cola European Partners. The new entity has signed a 10-year bottling agreement with Coca-Cola, with an option for a 10-year extension.
L Brands—The Victoria's Secret parent reported a 3 percent increase in same-store sales for July, better than the 2.3 percent consensus estimate of analysts surveyed by Thomson Reuters.
Costco—Costco reported comparable-store sales were flat in July, a better performance than the 0.6 percent drop that analysts were expecting.
Mondelez International—Mondelez now has activist investor William Ackman's Pershing Square as a stakeholder, with the firm taking a 7.5-percent stake worth about $5.5 billion. The maker of Cadbury chocolate and Oreo cookies issued a statement saying it welcomed Pershing as an investor.
Becton Dickinson—The medical products maker reported adjusted quarterly profit of $2.05 per share, 4 cents above estimates, with revenue essentially in line. Becton also raised its full-year forecast, and said the integration of Carefusion following purchase of that company is going well.
MobileEye—The maker of autonomous driving technology beat estimates by 2 cents with adjusted quarterly profit of 10 cents per share, with revenue beating estimates as well. The company also raised its full-year forecast.
Viacom—Viacom matched estimates with quarterly profit of $1.47 per share. However, revenue missed as the company did not release any major movies during the quarter.
Keurig Green Mountain—The single-serve coffee company reported adjusted quarterly profit of 80 cents per share, 1 cent above estimates. However, revenue was well below forecasts, and sales of its coffee pods fell for the first time ever. Keurig also lowered its sales and earnings forecasts and announced it would cut 5 percent of its workforce.
Generac—The maker of power generators missed estimates by 9 cents with quarterly earnings of 50 cents per share, and revenue was well below estimates as well. The miss came amid what the company calls a record low level of power outages.
CBS—CBS reported adjusted quarterly profit of 74 cents per share, 2 cents above estimates, with revenue essentially in line. CBS benefited from higher subscription fees and increasing revenue from affiliates.
Fitbit—Fitbit reported that its profit margins fell during the second quarter and would likely stay at current levels for the rest of the year. That news has put the fitness tracking device maker's shares under pressure, despite seeing revenue more than triple during the second quarter compared to a year earlier.
21st Century Fox—Fox earned an adjusted 39 cents per share for the second quarter, 2 cents above estimates, but revenue missed Street forecasts. The media company also announced a $5 billion stock buyback program.
Tesla—The automaker lost 48 cents per share for its latest quarter, smaller than the 60 cents Wall Street was predicting. Revenue was slightly above estimates, but investors are focusing on Tesla's second cut in its sales forecast in the past year.
Weight Watchers—Weight Watchers beat estimates by 2 cents with adjusted quarterly profit of 42 cents per share, though revenue fell below analyst forecasts. However, the weight loss company also raised its 2015 full-year outlook, based on improving member recruitment trends.
Herbalife—Herbalife reported adjusted quarterly profit of $1.24 per share, 13 cents above estimates, and revenue was slightly above forecasts. The nutritional products company raised its full-year earnings guidance, even as its sales are impacted by a stronger dollar.
JPMorgan Chase—JPM will move more than 2,100 jobs from New York City to New Jersey, according to The Wall Street Journal, and will get $19 million in subsidies from New Jersey for the move to Jersey City.
Barrick Gold—Barrick cut its dividend and is considering asset sales, as it copes with the lowest gold prices in more than five years. The dividend will be cut by 60 percent to 2 cents per share.
