Check out which companies are making headlines before the bell:
Wal-Mart Stores — The retail giant reported quarterly profit of 98 cents per share, 10 cents a share above estimates. Revenue was also above forecasts, as was the company's U.S. same-store sales increase of 1 percent. Wal-Mart is expecting U.S. comparable sales to be up by the same amount in the current quarter.
Dick's Sporting Goods — The sporting goods retailer earned 50 cents per share for its latest quarter, a penny a share above estimates. Revenue was slightly above forecasts. However, the company's current-quarter and full-year forecasts are below Street estimates, and Dick's sees comparable-store sales down 1 percent to 4 percent for the current quarter.
Advance Auto Parts — The autoparts retailer fell 9 cents a share short of estimates, with first-quarter profit of $2.51. Revenue also fell short. The company said its performance did not meet its expectations, and that it is moving to improve with "urgency." Separately, Advance Auto announced that Chief Financial Officer Mike Norona is leaving the company and that a search is underway for his successor.
Tesla Motors — The automaker plans to issue $2 billion in new stock. The funds would be used to accelerate the production of its Model 3.
Monsanto — The agricultural chemicals maker is the target of an unsolicited takeover bid from German drug and chemical company Bayer. Monsanto acknowledged receiving the proposal, but neither company released any proposed terms of the deal. Monsanto currently has a market capitalization of about $42 billion.
FMC Technologies — The provider of oil and gas industry technology will combine with Paris-based Technip in an all-stock deal. Technip shareholders will receive two shares in the combined company for each share they now hold, while FMC shareholders will get one share for each share they currently hold.
Church & Dwight — The maker of Arm & Hammer baking soda and other consumer products will get a $23 billion takeover bid from British consumer goods company Reckitt Benckiser, according to published reports.
Cisco Systems — Cisco reported adjusted quarterly profit of 57 cents per share, 2 cents a share above estimates. Revenue also beat forecasts. The maker of network equipment saw particularly strong demand for its security products.
Salesforce.com — Salesforce earned an adjusted 24 cents per share for its latest quarter, 1 cent a share above estimates. Revenue also beat forecasts. The business software company also raised its full-year forecast as demand for its cloud-based sales and marketing software increases.
Urban Outfitters — Urban Outfitters matched forecasts by earning 25 cents per share for its latest quarter, while revenue came in above analysts' estimates. Same-store sales for the apparel retailer rose 1 percent during the quarter, surprising analysts who had expected a decline. However, the company also said May sales have started out slower than expected and slower than the first quarter's pace.
L Brands — L Brands came in 4 cents a share ahead of Street estimates, with adjusted quarterly profit of 59 cents per share. But revenue came in below estimates. The Victoria's Secret parent also lowered its full-year earnings guidance as sales continue to be weak.
General Motors — The automaker is expected to announce plans to compensate owners of SUVs over inflated fuel economy claims, according to a Reuters report.
Viacom — Viacom's board of directors has voted to stop paying controlling shareholder Sumner Redstone, according to The Wall Street Journal. That comes amid the ongoing legal fight over Redstone's mental capacity.
Merck — Merck's melanoma drug Keytruda showed promise in a clinical trial, successfully extending survival rates among patients.
American Eagle Outfitters — American Eagle reported quarterly profit of 22 cents per share, 4 cents a share above estimates. Revenue was also above forecasts. Sales and profit margins for the apparel retailer have been improving following a revamp which saw the company close stores and expand its online presence.
