Check out which companies are making headlines before the bell:
McDonald's—The restaurant chain saw comparable store sales fall both globally and in all its individual regions, but the drops were smaller than the Street had expected.
Transocean—The oilfield services company reported quarterly profit of 96 cents per share, 13 cents above estimates, with revenue also above consensus. Transocean had delayed its planned earnings report on Friday and announced a $2.76 billion impairment charge related to a precipitous drop in day rates for its oil rigs.
Gogo—The provider of in-flight internet services lost 29 cents per share for its latest quarter, 3 cents wider than expected, with revenue matching forecasts. Gogo does point out that it chalked up its first $100 million quarter for revenue, and that new airline partnerships should drive its results going forward.
WhiteWave—The maker of popular food brands including Land O'Lakes reported adjusted third quarter profit of 27 cents per share, 1 cent above estimates, with revenue beating as well. WhiteWave was helped by particularly strong performance in North America.
Pfizer—Jefferies made Pfizer its "Top Global Pick," citing positive data on a number of pipeline drugs as well as restructuring and merger activity.
FireEye—The cyber security products maker's stock was added to the "Focus List" at JPMorgan Chase, based on its growth prospects. At the same time, the firm removed Akamai Technologies from that list, calling it a near-term trade whose thesis has now played out.

General Motors—The automaker ordered 500,000 replacement ignition switches nearly two months before it told federal safety officials of problems that eventually prompted massive recalls, according to the Wall Street Journal.
