Check out which companies are making headlines before the bell:
Allergan — The drugmaker announced a new $10 billion share buyback program, planning to execute up to half that amount over the next four to six months. Separately, Allergan reported adjusted quarterly profit of $3.04 per share, beating estimates by 3 cents a share.
Lumber Liquidators — The flooring maker lost an adjusted 35 cents per share for its latest quarter, 11 cents a share wider than expected. Revenue was below forecasts, as well. Lumber Liquidators saw same-store sales fall 13.9 percent compared to a year earlier.
Gap Inc. — The apparel retailer posted lower-than-expected quarterly sales and also issued an earnings warning. Gap has been hurt by weak demand at both the Banana Republic and Old Navy chains.
Dean Foods — The company is buying the manufacturing and retail ice cream business of Friendly's Ice Cream for $155 million in cash. Separately, Dean beat estimates by 7 cents a share, with adjusted quarterly profit of 45 cents per share. However, revenue was very slightly below forecasts.
Norwegian Cruise Line — The cruise ship operator matched estimates with adjusted quarterly profit of 38 cents per share. Revenue was below Street forecasts, however, due in large part to softness in the European market.
Hasbro — The toymaker's stock was downgraded to "neutral" from "overweight" at Piper Jaffray, which said the stock is fairly priced heading into a time of year that is traditionally off season for the toy industry.
Stamps.com — The internet postage service earned an adjusted $1.72 per share for its latest quarter, far above estimates of $1.06 a share. The company also raised its full-year outlook, as it continues to successfully integrate recent acquisitions.
SolarCity — SolarCity posted an adjusted loss of $2.56 per share, wider than the $2.32 a share expected by analysts. The solar company's revenue did beat Street forecasts, but the company also cut its forecast for solar panel installations for 2016.
LendingClub — The online lender remains in the news, following yesterday's ouster of CEO Renaud Laplanche. The Wall Street Journal reports that board member and former Morgan Stanley CEO John Mack joined Laplanche is investing in an outside fund in which the company was also considering an investment.
United Continental — United reported a 1.9 percent drop in revenue passenger miles for April compared to a year earlier. The airline maintained its prior forecast for a 6.5 percent to 8.5 percent decline for the second quarter, pointing to a stronger dollar, travel reductions from oil industry customers, and other factors.
Rackspace — Rackspace reported quarterly profit of 37 cents per share, 15 cents a share above estimates. Revenue was essentially in line with expectations. The cloud computing company, however, gave a lower-than-expected revenue outlook for the current quarter. Rackspace is in the midst of a transition to an emphasis on services.
Hertz Global — Hertz lost 12 cents per share for its latest quarter, 11 cents a share wider than expected. The car rental giant's revenue also fell below forecasts. Hertz has been impacted by a worldwide decline in rental prices, but it continues to back its prior 2016 forecast as it cuts costs.
Zoetis — Zoetis is on the watch list following a New York Times report that investor Bill Ackman's Pershing Square is cutting its stake in the animal vaccine maker. Pershing is said to be selling 16.85 million shares, which would cut its stake to 25 million shares.
Nokia — Nokia reported lower-than-expected sales of telecom equipment for its first quarter, and it also said its full-year earnings would fall as demand for mobile equipment weakens in key markets. This marks the first earnings report for Nokia since it took control of Alcatel-Lucent in January.
Baidu — Baidu was ordered by China regulators to change its advertising practices. That follows an investigation into the death of a college student who had cancer and had taken a therapy found through a Baidu ad.
