Check out which companies are making headlines before the bell:
Dow Chemical, DuPont – The two chemical companies have received European Commission approval for their planned merger, with some divestment conditions. The deal still needs U.S. approval, but many analysts have considered Europe's approval the most difficult to obtain.
Health-care stocks – The entire sector is on watch today, following the Friday afternoon withdrawal of the GOP health-care reform bill.

Cal-Maine Foods – The egg producer fell 12 cents a share short of forecasts, with quarterly profit of nine cents per share. Revenue was well short of estimates, as well. The company said the egg market has been extremely volatile, with the latest results a reflection of lower market prices and weaker demand.
G-III Apparel – The maker of fashion and athletic apparel reported an adjusted quarterly loss of 16 cents per share, six cents a share wider than expected. Revenue also fell short of Street estimates. The company said it was pleased with its performance in the face of retail headwinds and the near-term dilutive effect of its Donna Karan acquisition.
