Check out which companies are making headlines before the bell:
FedEx–The shipping giant earned $2.10 per share for its first quarter, beating estimates of $1.96, while revenue also beat consensus. Separately, FedEx is raising its U.S. shipping rates by an average of 4.9 percent in January.
Lennar–The home builder earned 78 cents per share for its third quarter, nine cents above estimates, with revenue also above forecasts. Lennar's quarter was fueled by a surge in new orders.
General Mills–The food producer earned 61 cents per share, excluding certain items, eight cents short of estimates. Revenue also was below consensus, with the company citing challenging U.S. market conditions, among other factors.
Auxilium Pharmaceuticals–The drug maker said it would examine a $2.2 billion takeover bid from specialty health care company Endo International. Endo is offering $28.10 per share in cash and stock, a premium of nearly 31 percent over yesterday's close. Auxilium is in the process of buying Canadian drug maker QLT, and said it was not planning any changes to that transaction.
Adobe Systems–Adobe reported fiscal third quarter profit of 28 cents per share, excluding certain items, two cents above estimates. Revenue, however, was slightly below consensus, and the software producer also saw higher operating expenses and weaker profit margins. It also issued conservative guidance for the current quarter.
DuPont–DuPont should be broken up, according to activist investor Nelson Peltz's Trian Fund Management. Peltz sent a letter to DuPont's board, saying the company's current structure is destroying shareholder value.
Boeing–Boeing and SpaceX have won contracts to build so-called "space taxis" for NASA.
Sony–The electronics giant warned that it will report a much larger than expected loss for the fiscal year ending in March, and will not pay a dividend. Sony cites its struggling smartphone business for the revised guidance, which will see Sony's net loss at an estimated 230 billion yen compared to the prior forecast of 50 billion yen.
–The company said its Canadian unit will apply for protection from creditors while it looks at restructuring alternatives. The steel maker also said it will not proceed with planned investments and expansions at plants in Minnesota and Indiana.
Rackspace–Rackspace has ended efforts to find a possible buyer, after hiring bankers back in May to review strategic options. The cloud computing services company also named President Taylor Rhodes as CEO, while former CEO Graham Weston becomes non-executive chairman.
American Airlines Group–The carrier's passenger service agents have voted to unionize for their first time in their history. The vote encompasses about 14,500 agents at American airlines and U.S. Airways.
Credit Suisse–The bank has been asked by the Federal Reserve to answer questions it has on the bank's involvement with leveraged loans, according to the Wall Street Journal.
