Check out which companies are making headlines before the bell:
UnitedHealth–The health insurer reported second quarter profit of $1.42 per share, 16 cents above estimates. Revenue beat forecasts as well, and the company also raised its full year revenue forecast.
Mattel–The toymaker earned three cents per share for the second quarter, excluding certain items, well below estimates of 18 cents, with revenue below analyst consensus. However, the company said various initiatives have positioned them for better performance in the second half of the year and beyond.
Blackstone–The private equity firm trounced expectations with its latest quarterly earnings report, helped by performance fees that nearly doubled.
Morgan Stanley–The firm reported second quarter profit of 60 cents per share, excluding certain items, five cents above estimates, with revenue also above estimates. The quarter's results were driven by strong investment banking and wealth management.
Philip Morris International–The tobacco producer earned $1.41 per share for the second quarter, excluding certain items, 17 cents above estimates. Revenue also beat estimates, although profit and revenue did decline because of falling cigarette shipment volume.
Autonation–The auto retailer missed estimates by four cents with second quarter profit of 83 cents per share, although CEO Mike Jackson noted that it was the 15th consecutive quarter of double-digit earnings growth.
EBay– The online auction site reported second quarter profit of 69 cents per share, excluding certain items, one cent above estimates. However, the company's current quarter forecasts for earnings and revenue are both below Street forecasts. Results were boosted largely by growth in the PayPal operation.
Yum Brands–The restaurant operator earned 73 cents per share for the second quarter, missing estimates by one cent, with its revenue falling short of predictions as well. However, Yum did see its business bounce back in the troubled China market, with same-store sales in China up 15 percent.
KeyCorp–The bank earned 27 cents per share, excluding certain items, for the second quarter, two cents above estimates. KeyCorp also announced it was buying investment firm Pacific Crest Securities for an undisclosed amount.
SanDisk–The chip maker earned $1.41 per share for its latest quarter, above estimates of $1.39, with revenue also beating forecasts. However, its current quarter revenue forecast is below Street predictions, saying it won't be able to meet fulfill soaring demand for solid state drives and memory chips.
Las Vegas Sands–The casino operator fell five cents short of estimates with second quarter profit of 85 cents per share, excluding certain items, and revenue was shy of estimates as well. The miss comes despite healthy growth in the company's Macau operations.
Select Comfort–The mattress retailer beat estimates by two cents with second quarter profit of 16 cents per share, and revenue was also above forecasts. Select notched a seven percent rise in same-store sales, and its earnings topped Street expectations for the second straight quarter following five consecutive misses.
United Rentals–United Rentals reported second quarter profit of $1.65 per share, excluding certain items, 19 cents above estimates. Revenue was also ahead of analyst predictions, with the equipment rental company seeing particular strength in nonresidential construction.
Orbitz—The online travel site operator said Travelport, its largest shareholder, will seek to cut its stake in half. It also forecast $248 million in revenue for the second quarter, which would top analyst estimates of $243 million.
Novartis–Novartis missed estimates with its latest quarter sales, but the drug maker confirmed its prior full-year guidance. It also said it will seek to save on more costs to boost its profit margins.
