Anheuser-Busch and InBev are definitely not going to be best buds (to coin a phrase).

Anheuser-Busch’s directors have rejected In Bev’s buyout offer, saying the bid is inadequate and "undervalues the unique assets and prospects of Anheuser-Busch."

Hours after the action by A-B’s board, InBev filed a lawsuit in Delaware seeking to oust all 13 Anheuser-Busch directors.
