Check out which companies are making headlines before the bell on Monday:
Boeing - Indonesia's Lion Air, traditionally a Boeing client, has struck a deal with rival Airbus to buy 234 jets worth as much as $24 billion at list prices.
Anheuser-Busch InBev, Constellation Brands - Anheuser-Busch and the U.S. Justice Department have jointly asked a court to extend a stay on current litigation involving its $20.1 billion deal to buy Mexico's Grupo Modelo. The beer brewer issued a statement saying it has made substantial progress in resolving DOJ's concerns about the deal. The biggest beneficiary of this news from a stock perspective may be Constellation, which is buying assets from AB InBev to help satisfy DOJ's concerns.
United Technologies - The Dow Jones Industrial Average component has been upgraded to "buy" from "neutral" at Citigroup, citing an attractive valuation and the end of a transition period followings its acquisition of Goodrich.
