Check out which companies are making headlines before the bell:
Goldman Sachs—The investment bank reported third quarter profit of $4.57 per share, well above estimates of $3.21, with revenue also above estimates. CEO Lloyd Blankfein said improved economic conditions in the U.S. are among the factors helping Goldman's results.
Delta Air Lines—The airline beat Street estimates by two cents with third quarter profit of $1.20 per share, excluding certain items. Delta makes note of "solid" margin expansion, though it said it still has work ahead of it to achieve its financial goals.
Mattel—The toy maker missed estimates by six cents with per-share profit of 98 cents per share, excluding certain items, and revenue was short of consensus as well as sales of its flagship Barbie line slumped 21 percent.
UnitedHealth—The health insurer beat estimates by 10 cents with third quarter profit of $1.63 per share, though revenue was very slightly shy. The company's results benefited from lighter use of medical services during the quarter.
Baker Hughes—The oilfield services provider saw third quarter earnings fall short of estimates by 11 cents at $1.02 per share, excluding certain items. Revenue also missed estimates, as geopolitical events and lower Gulf of Mexico activity hurt results.
Blackstone—The asset manager reported economic net income of 66 cents per unit, missing estimates by six cents, though revenue did beat estimates, and both its economic net income and its revenue reached record highs.
Winnebago—The recreational vehicle maker reported fiscal fourth quarter profit of 48 cents per share, two cents above estimates, with revenue beating forecasts as well. Sales have been improving in recent quarters as the company introduces new products to the marketplace.
Baxter International—The medical products maker beat estimates by four cents with third quarter profit of $1.35 per share, excluding certain items. Its results were helped by strong growth in the U.S. market.
Philip Morris International—The tobacco maker earned $1.39 per share for the third quarter, excluding certain items, beating estimates by six cents. Revenue also beat estimates despite falling cigarette shipment volumes.
American Express—The financial services giant beat estimates by four cents with quarterly profit of $1.40. Revenue was essentially in line with consensus, with Amex benefiting from an increase in card spending by U.S. customers.
EBay—The e-commerce company earned 68 cents per share for its third quarter, excluding certain items, one cent above estimates. But EBay also cut its 2014 revenue forecast, marked by a lower than expected outlook for the holiday shopping season.

Las Vegas Sands—The company fell short of estimates by one cent with third quarter profit of 83 cents per share, excluding certain items. The casino operator's revenue also fell short of forecasts, owing in part to slower business in Macau.
