Check out which companies are making headlines before the bell on Tuesday:
Goldman Sachs—Goldman earned $3.70 per share for the second quarter, well above estimates of $2.82. Revenue also beat consensus, with CEO Lloyd Blankfein saying the overall operating environment has improved.
Coca-Cola — The soft drink giant earned 63 cents per share for the second quarter, excluding certain items, matching expectations. Revenue and case volume were below estimates in the quarter, with Coke saying it was "not happy" with its performance.
General Motors— Goldman Sachs added GM stock to its "conviction buy" list, saying positive near-term catalysts are not yet fully priced in.
Buffalo Wild Wings —Baird Equity Research downgraded the restaurant operator to "neutral" from "outperform", saying the earnings picture remains positive but a number of risks are worth monitoring.
Honeywell —Honeywell issued an updated statement about the Boeing 787 fire last week at Heathrow Airport. The company has been participating in the investigation, with an emergency transmitter made by Honeywell being investigated as a possible cause. Honeywell emphasizes that it is premature to speculate on any conclusions in the case at this time.
Cintas — The company reported fiscal fourth quarter profit of 69 cents per share, one cent below estimates. Revenue was in line with consensus, but its full year forecast falls short of analyst expectations. The maker of uniforms points to uncertainty generated by the overall economy and the effects of the Affordable Care Act.
Marathon Petroleum— The refining company is forecasting second quarter earnings of $1.87 - $1.92 per share, well below estimates of $2.62. Marathon points to higher costs for the crude that it processes, similar to the profit warning issued by competitor Valero Energy last week.
J.M. Smucker— The food producer raised its quarterly dividend to $0.58 per share from 40.52, an increase of nearly 12 percent for its shareholders.
McDonald's — The burger giant will open its first restaurant in Vietnam, with the son-in-law of Vietnam's prime minister as the main franchise partner.
Baidu — The company will buy smartphone app maker 91 Wireless in a $1.9 billion deal. 91 Wireless is the owner of two app distribution platforms that have distributed more than 10 billion apps. Baidu is the company behind China's most popular search engine.
Anadarko Petroleum — Anadarko will face a narrowed lawsuit over the 2010 Gulf oil spill. A judge ruled that Anadarko would have to face a suit accusing it of defrauding shareholders, but also said plaintiffs could only sue over one statement from the company regarding the blown out Macondo well.
Dell — The PC maker remains on our watch list, with a shareholder vote over founder Michael Dell's buyout bid set for Thursday. Investor Carl Icahn has been pushing alternative proposals, but the vote at present is considered too close to call.
