Take a look at some of Tuesday's morning movers:
AT&T - The telecommunications giant earned $0.66 per share for the second quarter, three cents above estimates. Revenue was essentially in line, with AT&T also reporting a drop in customer churn and an increase in operating margins.
UPS - The delivery company earned $1.15 per share for the second quarter, two cents shy of estimates, with revenues also light. UPS also cut its full-year forecast, citing economic uncertainties in the U.S. and Europe, among other factors.
DuPont - The chemical producer earned $1.48 per share, excluding certain items, for the second quarter, two cents above estimates. Revenue was slightly short of estimates, and the company issued a cautious outlook for the year because of a slowing global economy.
Whirlpool - The world's largest appliance maker earned $1.55 per share, excluding certain items, for the second quarter, nine cents short of estimates. Revenue was on the light side, and Whirlpool was yet another company to cite Europe and a strong dollar as negative factors.
Altria - The tobacco producer earned $0.59 per share for the second quarter, beating estimates by two cents. Revenue was also better than estimates, as higher prices helped offset flat cigarette volumes.
Lexmark - The printer maker fell four cents short of consensus with second-quarter earnings of $0.89 per share, excluding certain items. Revenue was short of the mark as well, as soft sales gave Lexmark a third straight quarter of revenue declines.
Biogen Idec - Strong sales of the company's multiple sclerosis drug helped Biogen score a sizable beat, with second-quarter profit of $1.82 per share versus estimates of $1.56 a share.
Under Armour - The apparel maker earned $0.06 per share for the second quarter, a cent above estimates. Revenue was also above Street forecasts, and the company raised its full-year forecast.
Lockheed Martin - The defense contractor earned $2.38 per share for the second quarter, well above estimates of $1.91. Revenue beat consensus as well, and Lockheed also raised its full-year outlook.
Domino's Pizza - The pizza store operator beat estimates by a cent with quarterly profit of $0.47 per share, but revenue came in on the light side. A stronger U.S. dollar and fewer company-owned restaurants impacted revenues during the quarter.
Texas Instruments - The company beat estimates for its latest quarter, but issued an outlook below consensus forecasts. The chipmaker earned $0.44 per share for the second quarter, three cents above estimates. It said, however, that third-quarter earnings per share will come in at $0.41 to $0.49 per share versus estimates of $0.50. The company cited customer caution amid global economic uncertainty.
Baidu - Baidu earned $1.24 per share for its second quarter, 13 cents above estimates, with revenue also above analysts' forecasts. Revenue growth remains strong, although the China Internet search firm is also seeing rising costs.
VMWare - VMWare earned $0.68 per share for the second quarter, two cents above estimates. Separately, the software maker announced it’s buying privately held Nicira for $1.05 billion cash, its biggest acquisition yet. Nicira specializes in software the lets customers create virtual networks.
DeVry - The company is warning that profit for its fiscal fourth quarter will come in at $0.43 to $0.46 per share, far short of analysts' estimates of $0.78. Revenue will also fall short of consensus, and the for-profit education company said it plans to cut 570 jobs to lower costs.

The trial focused on people who carry a gene mutation that gives them a higher risk of contracting the disease. Results for patients who don’t carry this mutation have yet to be released.
United Technologies - The Dow Jones Industrial Average component, which just sold its RocketDyne unit, may be about to sell its Hamilton Sundstrand industrial businesses. Reuters reports private-equity firms BC Partners and Carlyle Group are in advanced talks to jointly buy those businesses, which could bring in more than $3.5 billion.
BP - The oil company is in talks with Russia’s Rosneft to sell its 50 percent stake in joint venture TNK-BP, according to a statement by Rosneft. The stake is estimated to be worth $20 billion to $30 billion.
