Check out which companies are making headlines before the bell on Tuesday:
AOL – The online media company reported third quarter earnings of 55 cents per share, excluding certain items, four cents above estimates, with revenue beating consensus as well. AOL's results were helped by a 13.5 percent increase in ad sales.
Michael Kors – The retailer beat estimates by three cents with fiscal second quarter profit of 71 cents per share. Revenue also came in above consensus, and the company also raised its outlook for the year as it continues to build sales momentum.
Becton Dickinson – The maker of medical supplies reported fiscal fourth quarter profit of $1.54 per share, excluding certain items, beating estimates by eight cents, with revenue also above estimates. Becton gave a full-year forecast for the new fiscal year slightly below Street estimates, but analysts point out that the company has a history of giving conservative guidance.
Cognizant Technology – The technology services firm earned $1.05 per share, beating estimates by four cents, with revenue also above forecasts. Cognizant's customers spent more on technology consulting services during the quarter, especially in the financial sector.
R.R. Donnelley– Donnelley earned 38 cents per share for its third quarter, excluding certain items, two cents above estimates. Revenue also exceeded consensus, and the provider of printing and communication services also raised its full-year revenue forecast.
Regeneron Pharmaceuticals– The drug maker earned $1.25 per share for the third quarter, beating estimates by 35 cents, with revenue trouncing consensus as well. Regeneron's results have been driven by strong sales growth of its Eyelea macular degeneration treatment.
Emerson Electric – Emerson reported fourth quarter profit of $1.18 per share, excluding certain items, seven cents above estimates, with revenue also beating forecasts. The beat came despite a macroeconomic environment that the electrical equipment maker describes as "difficult".
Endo Health–The specialty pharmaceutical company is buying Canada's Paladin Labs for $1.6 billion dollars, paying a premium of more than 20 percent to Paladin's Monday closing price in Canadian trading.
Anadarko Petroleum– Anadarko posted third quarter earnings of $1.13 per share, excluding certain items, three cents below estimates, with revenue essentially in line. The miss comes despite record production of oil and natural gas for Anadarko.
CF Industries- CF earned $3.89 per share, excluding certain items, for the third quarter, missing estimates by 11 cents. Revenue also fell below estimates as weak global fertilizer markets helped push down prices.
Marathon Oil -The energy company reported third quarter profit of 87 cents per share, excluding certain items, ten cents above estimates, with revenue also above forecasts. Marathon was helped by a surge in oil and gas production.
LeapFrog– The toy maker beat estimates by five cents with third quarter profit of 37 cents per share. The company's revenue was shy of estimates, however, as is its full year revenue and EPS forecast. Leapfrog cites a weak retail environment as well as fewer shopping days between Thanksgiving and Christmas.
Weatherford International —Weatherford topped estimates by two cents with third quarter profit of 23 cents per share, excluding certain items. Revenue for the oilfield services company did fall short of forecasts, however, as business in North America slipped.
Hertz Global —Hertz earned 73 cents per share for the third quarter, two cents above estimates, helped by good results at its Dollar Thrifty unit.
Jamba – The smoothie operator reported third quarter profit of 15 cents per share, five cents below estimates, as same-store sales fell 3.4 percent from the same period a year ago. However, Jamba does see positive comparable store sales for 2014.
T-Mobile US – The wireless services provider saw third quarter revenue grow 7.4 percent, and post subscriber additions above Street estimates.
Mosaic – The fertilizer producer earned 51 cents per share for the third quarter, four cents below estimates, with revenue shy of consensus as well. Mosaic's bottom line was impacted by lower prices for potash and phosphate.
CVS Caremark – CVS earned $1.05 per share for the third quarter, three cents above estimates, with revenue also above forecasts. The company also raised its yearly outlook, on more prescription processing and better sales at its namesake drugstore chain.
