Check out which companies are making headlines before the bell:
Tiffany– The luxury goods retailer reported quarterly profit of $1.47 per share, excluding certain items, five cents below estimates, with sales also falling slightly short of consensus. Its current fiscal year guidance also falls below Street estimates. Nonetheless, the company said it is pleased with its performance over the past year, which included record sales and earnings.
Darden Restaurants–The parent of Red Lobster and Olive Garden matched estimates with quarterly profit of 82 cents per share. However, Darden had warned earlier this month that severe winter weather would impact its bottom line.
Walgreen–The drug store chain's shares were cut to "sell" from "hold" at Cantor Fitzgerald, which said the benefit of Walgreen's alliance with Alliance Boots is now fully reflected in the share price.
ConAgra–Goldman Sachs cut the food producer's shares to "neutral" from "buy", saying the company's turnaround is more protracted and more expensive than expected.
Zions Bancorp–The bank was the only one of 30 to fail the Federal Reserve's stress tests. Zions is a first-time participant in the test for capital requirements, and has already said it will resubmit its plan to raise capital.
Boeing–Goldman downgraded the aerospace giant to "neutral" from "buy". The bank said aerospace investors should be focusing less on the original equipment market and more on aftermarket products, based on better near-term growth prospects.
WellPoint–The health insurer raised its 2014 earnings forecast to "greater than $8.20/share" from its prior estimate of more than $8. However, that raised forecast is still below consensus estimates of $8.37.
Nike–The maker of athletic footwear and apparel earned 76 cents per share for its third quarter, beating estimates by four cents, with revenue also beating consensus. Nike said its global sales have surged ahead of this summer's World Cup tournament in Brazil this summer. The company did say currency headwinds would cut earnings growth in the current quarter as well as fiscal 2015.
United Technologies–Goldman upgraded the company's shares to "buy" from "neutral", saying the "stars were aligning" for the company's end markets.
Discover Financial–The company proposed raising its quarterly dividend by 20 percent to 24 cents per share, as well as a $1.6 billion stock buyback. Those actions still need a "non-objection" from the Fed, as well as approval from Discover's board.
Symantec–The maker of anti-virus software has terminated chief executive officer Steve Bennett, naming board member Michael Brown as interim CEO. Symantec said the move was "not precipitated by any event or impropriety."
Time Warner Cable–CEO Rob Marcus if Comcast's deal to buy the company is successfully completed. A regulatory filing said Marcus would get $20 million in cash, $56.5 million in equity, and a $2.5 million bonus if certain targets are met. Comcast is the owner of NBCUniversal, the parent company of CNBC and CNBC.com.
General Motors–New CEO Mary Barra will testify on April 1 to the House Energy and Commerce Committee, which is investigating the automaker's handling of its long-running problem with defective ignition switches.
Deutsche Bank–The bank failed to win dismissal of four U.S. lawsuits over its sales of mortgage backed securities ahead of the 2008 financial crisis.
Discovery Communications–Chairman John Hendricks will retire from the media company's board after the annual shareholder meeting on May 16. Hendricks was the creator of the Discovery Channel and served as the company's CEO until 2004.
Compuware–The company is said to be drawing interest from private equity firms Vista Equity and Thoma Bravo, according to a Bloomberg report. Late last year, the Financial Times had reported interest in the firm from those two firms as well as Bain Capital and Golden Gate Capital.
Ann– Golden Gate Capital has taken a 9.5 percent stake in the parent of Ann Taylor and Loft. The firm said it is in the early stages of discussions with the company about boosting shareholder value.
Duke Energy–Duke was cited by North Carolina regulators for environmental violations, with the state saying the company illegally pumped 61 million gallons of contaminated water from a coal ash pit into the Cape Fear River.
