Check out which companies are making headlines before the bell:
Yahoo — Verizon is buying Yahoo's operating businesses for $4.8 billion in cash. The deal does not include Yahoo's stakes in Alibaba and Yahoo Japan, and also excludes certain patents and Yahoo's cash.
Carmike Cinemas — The movie theater chain will be bought by rival AMC Entertainment in an improved deal worth $33.06 per share in cash and stock — that's a more than 10 percent improvement over AMC's original bid.
Allergan — Credit Suisse initiated coverage on Allergan with an "outperform" rating, saying the drug maker has a broad and underappreciated pipeline.
Kimberly-Clark — The consumer products maker reported quarterly profit of $1.56 per share, eight cents a share above estimates. Revenue also beat Street forecasts. The company said it performed well in a challenging economic environment.
Hershey — The Hershey Trust — the chocolate maker's largest shareholder — agreed to make significant governance changes, according to Dow Jones. Those changes could potentially boost the chances that a previously rejected $23 billion takeover offer from Mondelez International will be in play once again.

Danaher — The designer and manufacturer of industrial and consumer products beat estimates by three cents a share, with adjusted quarterly profit of $1.25 per share. Revenue also came in above forecasts. The company said it did well in what it calls "challenging" economic conditions.
