Check out which companies are making headlines before the bell:
Starbucks—The coffee and beverage giant posted fiscal third-quarter earnings of 67 cents per share on $4.15 billion in revenue, barely edging out Wall Street's consensus forecast. Seattle-based Starbucks cited a big push into food offerings and a revamped breakfast menu, including the introduction of an Oprah Winfrey-branded chai tea, as helping to boost the quarter's performance.
Visa—The world's largest credit and debit card company posted an 11 percent jump in quarterly profit as more people around the world used plastic instead of cash to make purchases. Visa beat Wall Street's estimates with net income of $1.36 billion, or $2.17 per Class A share, in the third quarter, from $1.23 billion, or $1.88 per Class A share, a year earlier.
Amazon.com—The Internet retail giant gave markets an unpleasant surprise by posting a wider-than-expected loss of 27 cents a share, missing expectations for a loss of 15 cents a share. Although sales of $19.34 billion matched forecasts, helped by a batch of new innovations that include a smartphone and Sunday delivery, Wall Street was not impressed. The stock was down more than 10 percent in extended-hours trading.
