Check out which companies are making headlines before the bell:
Campbell Soup — The food company reported adjusted quarterly profit of 46 cents per share, 4 cents a share below estimates. Revenue was just shy of forecasts. Campbell said it was not pleased with the quarterly results, pointing specifically to "execution issues" with its Campbell Fresh business. Its full-year EPS forecast of $3 to $3.09 is also shy of the consensus estimate of $3.14 a share.
Joy Global — The mining equipment maker earned an adjusted 10 cents per share for its latest quarter, 2 cents a share below estimates. Revenue was also below forecasts. Joy said that market conditions remain "extremely challenged."
Salesforce.com — The cloud software company reported adjusted quarterly profit of 24 cents per share, 2 cents a share above estimates. Revenue was very slightly above forecasts, but its current-quarter revenue and profit estimates came in below Street estimates.
Shoe Carnival — Shoe Carnival's earnings fell 5 cents a share below estimates, with quarterly profit of 22 cents per share. Revenue was below forecasts, as were the shoe retailer's comparable-store sales.
Box — Box lost an adjusted 14 cents per share for its latest quarter, 5 cents smaller a share than estimated. The online file sharing company saw revenue come in above Street forecasts, however, and Box raised its full-year outlook on improving sales.
Charter Communications — The cable operator's stock will replace EMC in the S&P 500 after the close of trading on September 7, with EMC being acquired by privately held computer maker Dell.
Apple — Apple CEO Tim Cook told a Dublin radio station that the company expects to repatriate billions of dollars back to the U.S. next year, although he did not specify an amount. He also called the European Union's $14.5 billion tax bill for the company "total political crap."
Las Vegas Sands, Wynn Resorts — Shares in the casino operators could benefit from news that gaming revenue in Macau rose by 1.1 percent in August, the first monthly year-over-year growth in the Chinese territory since May of 2014.
Wal-Mart Stores — The retail giant is beginning its holiday layaway program tomorrow, two weeks early, hoping to get a jump on the holiday shopping season.
Lazard — Lazard erred in its analysis of SolarCity's worth in its work advising the solar equipment company on its sale to Tesla Motors, according to a regulatory filing, undervaluing SolarCity by $400 million. However, the purchase price of $2.6 billion was within the valuation range even with the miscalculation factored in.
McDonald's — McDonald's named Executive Vice President Christopher Kempczinski as the new president of McDonald's USA as of the end of the year, following the retirement of current president Michael Andres.
JPMorgan Chase — The bank was given a stand-alone asset management license in China, according to a regulatory filing.
Costco — The discount retailer reported flat global comparable-store sales for August, and flat comps in the U.S., as well. Both measures had been expected to rise by 1.3 percent, according to estimates from Thomson Reuters.
Five Below — Five Below raised its forecast for the full year, after the discount retailer reported better-than-expected results for its most recent quarter. However, it gave downbeat guidance for the current quarter, which includes the back to school shopping season as well as Halloween.
