Check out which companies are making headlines before the bell:
Keurig Green Mountain– Coca-Cola is exercising its option to increase its stake in the coffee pod maker to 16 percent from 10 percent. That option was part of the February deal in which Coke acquired its original stake.
BP–The energy producer has signed a $3 billion five-year deal to provide liquefied natural gas to Kuwait.
Time Warner–Bernstein upgraded the stock to "outperform" from "market perform", on better earnings prospects, among other factors.
Hillshire Brands– JPMorgan Chase downgraded the stock to "neutral" from "outperform", saying it doesn't necessarily see the announced deal to acquire Pinnacle Foods as the ideal strategic maneuver.
DirecTV—Multiple reports say AT&T is in talks to buy the satellite TV provider for about $50 billion—or up to $95 per share. DirecTV shares had closed at $87.16 on Monday.
Rackspace Hosting–Rackspace reported first quarter profit of 18 cents per share, beating estimates by six cents, with revenue above estimates as well. The web-hosting company saw increased demand for its services during the quarter.
Elizabeth Arden–Elizabeth Arden lost 84 cents per share for its third quarter, excluding certain items, far worse than analyst forecasts for a breakeven quarter. Revenues also fell well short of estimates, and the cosmetics maker said it is implementing a restructuring program and exploring strategic alternatives.
McKesson–The company reported fiscal fourth quarter profit of $2.55 per share, 15 cents above estimates, with revenue scoring a solid beat. The drug wholesaler was helped by stronger results in its drug distribution and technology solutions operations.
Credit Suisse–The bank could pay more than $2 billion to settle its tax case with U.S. authorities, according to Reuters. Multiple probes involve accusations that the Swiss bank helped U.S. citizens evade taxes.
Pfizer—CEO Ian Read is appearing Tuesday before the British parliament, trying to garner support for his company's bid for rival drug maker AstraZeneca. Pfizer has hinted it might improve its $106 billion offer if it can engage with AstraZeneca's board.
BlackBerry–The smartphone maker has unveiled a budget handset in the Indonesian market, trying to boost sales in emerging markets.
Vantiv–Vantiv is buying rival payment processor Mercury Payment Systems for $1.65 billion. Mercury is currently owned by private equity firm Silver Lake Group.
