Check out which companies are making headlines before the bell on Monday:
Boeing - The jet maker completed all of its certification testing for a revamped 787 battery system. That puts Boeing a key step closer to getting the grounded jet back into service. Separately, Reuters reports competitor Airbus may be close to sealing a $7 billion jet order from one of Boeing's most loyal customers, British Airways.
Constellation Brands, Anheuser-Busch InBev - The two companies and Grupo Modelo have reached an agreement in principle with the Justice Department over AB InBev's deal to buy the part of Grupo Modelo it doesn't already own. The revised deal gives control of Modelo beers sold in the U.S. to Constellation, in response to DOJ concerns that the original deal would stifle competition.
