Check out which companies are making headlines before the bell:
Sempra Energy – Sempra announced a deal to buy power transmission company Oncor for $9.45 billion in cash. Under terms of the deal, Sempra will own about 60 percent or Oncor's holding company, Energy Future Holdings. Sempra beat out Warren Buffett's Berkshire Hathaway, which had a $9 billion bid in place.
ADP – The payroll processing company's board unanimously voted not to nominate any of Pershing Square's three director candidates, following interviews with each. It said none of the candidates bring any additional skills or experience to the board. Pershing Square owns 8.3 percent of ADP and has called on CEO Carlos Rodriguez to be replaced.
Fiat Chrysler – The automaker denied a Reuters report that it is drawing buyout interest from China's Great Wall Motor, according to an unnamed company. Automotive News had reported last week that an unidentified "well-known Chinese automaker" had made an offer earlier this month. Fiat Chrysler said it had not been approached by Great Wall and that it is fully committed to its 2014-2018 business plan.
The Container Store – The maker of home and office storage products cut its full-year earnings outlook to 27 cents to 40 cents a share from the prior guidance of 37 cents to 49 cents a share, compared to the consensus estimate of 37 cents. The cut follows the announcement of an amendment to the company's senior secured debt, which will increase its interest costs.
Novartis – The drugmaker has begun clinical trials of an experimental drug that could be the first new malaria drug in many years.
Goldman Sachs – Goldman received approval for a license to trade equities in Saudi Arabia. The Saudi government had eased restrictions last year on foreign ownership in its stock market.
Electronic Arts – The video game maker is partnering with the National Football League to create an annual video game tournament.
Starbucks – Starbucks got a positive mention in this weekend's Barron's, which noted that the coffee chain's mobile order-and-pay feature has become extremely popular with customers and that the stock is at one of its cheapest valuations in years. The paper said the stock could rise 20 percent or more over the next 12 months.
Nike – Nike was downgraded to "hold" from "buy" at Jefferies, which also cut its price target on the stock to $60 from $75. Nike fell more than four percent Friday after athletic apparel and footwear retailer Foot Locker posted top-and-bottom line miss. Jefferies said Nike will face growing margin and growth pressure, putting its premium valuation in question.
Wal-Mart – The retail giant has filed a patent for a flying warehouse and a team of drones, as it seeks to improve delivery times and effectively compete with Amazon.com, which last year filed a patent for an "airborne fulfillment center."
Westlake Chemical – The chemical maker increased its quarterly dividend by nearly 10 percent to 21 cents per share.
