Earlier today, one of the most hyped M&A deals currently on the block was unexpectedly yanked, when seed giant Monsanto announced that it would drop its $46 billion takeover bid for Swiss pesticides firm Syngenta. While the deal was strongly resisted, it was largely expected it would pass as a result of the near-monopoly agri- biotech that would be formed as a result, and that MON would sweeten the offer enough until it got the target’s approval. It did not and as a result, Syngenta stock crashed earlier today, tumbling as much as 20%.
