Check out which companies are making headlines before the bell:
Best Buy—The electronics retailer reported adjusted quarterly profit of 37 cents per share, 8 cents above estimates, with revenue beating forecasts, as well. Comparable-store sales were up 0.6 percent, compared to consensus estimates of a 0.1 percent increase.
Omnicare—CVS Health is buying the pharmacy benefits manager for $10.4 billion in cash, or $98 per share. The value of the deal is $12.7 billion when assumed debt is included.
Hewlett-Packard—HP is selling 51 percent of its China-based data networking operation to China's Tsinghua Holdings.
Pfizer—Jefferies tapped the drug maker as its top global pharmaceutical pick, based on a positive outlook for its drug pipeline as well as other factors.
Nike—Jefferies began coverage on the shoe and apparel maker with a "buy" rating, both on its business outlook as well as the potential for shareholder-friendly moves.
Alibaba—Bernstein initiated coverage on the China-based online retailer with a "high conviction outperform" rating, saying the Street is underestimating the company's growth potential.
Williams-Sonoma—The retailer reported quarterly profit of 44 cents per share, 4 cents above estimates. Revenue was essentially in line, although comparable store sales increased more than expected. The company's outlook for the current quarter, however, is below Street forecasts.
Salesforce.com—Salesforce beat estimates by 2 cents with adjusted quarterly profit of 16 cents per share, while revenue was in line with forecasts. The business software provider also increased its full-year forecast on increased subscription and services revenue.
L Brands—The apparel retailer earned an adjusted 61 cents per share for its latest quarter, 1 cent above estimates, with revenue slightly below. The Victoria's Secret parent did raise its full-year guidance, but gave a current quarter forecast that falls below analyst estimates amid increased promotions in the industry.
NetApp—NetApp fell 7 cents short of estimates with adjusted quarterly profit of 65 cents per share. Revenue also fell short, as did the data storage equipment maker's current quarter forecast. The company has been hurt by falling sales to original equipment manufacturers, and NetApp also announced it would shed about 500 workers as part of a restructuring.
