Check out which companies are making headlines before the bell:

Best Buy – Best Buy beat estimates by six cents with adjusted profit of 41 cents per share, but its revenue was merely in line and its same store sales increase of 0.8 percent was only half of what analysts were expecting.

UnitedHealth Group – The health insurer cut its forecast for the year, mentioning lower than expected activity at the health care exchanges set up by the Affordable Care Act.

J.M. Smucker – The food company reported adjusted quarterly profit of $1.62 per share, 11 cents above estimates, with revenue very slightly above forecasts. Smucker was helped by its acquisition of Big Heart Pet Brands, as well as improved coffee sales.

Wendy's – Goldman Sachs added the restaurant chain's shares to its "Conviction Buy" list, based on prospects for accelerating same-store sales increases as well as impressive free cash flow numbers.

Sysco – Wells Fargo initiated coverage of the food services company with an "outperform" rating, saying Sysco is in the early stages of a multi-year turnaround after a series of setbacks.

Keurig Green Mountain – Keurig earned an adjusted 85 cents per share for its latest quarter, 15 cents better than estimates. The maker of single-serve coffee machines also scored a small beat on revenue, and raised its quarterly dividend by 13 percent. Sales did slow, but not as much as many analysts had expected.

Salesforce.com – Salesforce beat estimates by two cents with adjusted quarterly profit of 21 cents per share, with revenue also slightly above estimates. The provider of cloud computing services and software also gave an upbeat outlook for this year and next year, as sales accelerate.

L Brands – L Brands earned 55 cents per share for its latest quarter, three cents above estimates, with revenue essentially in line. The parent of Victoria's Secret and Bath & Body Works also raised its guidance for the year, although its outlook for the current quarter comes in below Street forecasts.

Raytheon – Raytheon increased its share buyback program by $2 billion. The defense contractor will buy back shares "from time to time" at the company's discretion depending on market conditions.

Square – Square will begin trading today on the New York Stock Exchange, after its initial public offering priced at $9 per share. That was below the expected $11 to $13 range, and also below the $15.46 per share price that investors paid in the mobile payments company's most recent private financing round.

Match – Match will begin trading today on the Nasdaq, after the dating website operator's IPO priced at $12 per share, at the low end of the expected range. Match is the operator of Tinder, Match.com, and OkCupid.

Allergan – Allergan and Pfizer are accelerating their takeover talks, as the U.S. Treasury moves to clamp down on tax inversion deals. Reuters reports that the deal being discussed would see Pfizer pay $370 to $380 per share for Allergan, compared to Allergan's Wednesday closing price of $310.80. However, the report said that an agreement is not imminent.

Yahoo - Yahoo is reportedly being pressured by activist investor Starboard Value to halt its planned spinoff of its Alibaba stake. The Wall Street Journal reports Yahoo is being urged instead to sell its Internet business.

Ford - A tentative four-year labor deal between Ford and the UAW appears set to be rejected, with votes running more than 2-1 against the pact.

SunEdison – The stock is under pressure on reports that Blackstone has no plans to invest in the solar company, contrary to earlier reports that it was considering such an investment. Investors are increasingly concerned about the company's access to capital, following its rapid expansion.
