China National Chemical Corp. is making history with its nearly $44 billion deal to acquire Swiss agrichemical producer Syngenta AG (SYNT). The buyer, commonly known as ChemChina, struck China's largest ever overseas takeover agreement almost six months after seeds market leader Monsanto Co. (MON) abandoned an acrimonious attempt to buy the Swiss company. ChemChina beat several other suitors in the latest round of discussions. Syngenta chairman Michel Demare suggested in December that these included Monsanto again, as well as Bayer AG and BASF SE. ChemChina agreed to offer $465 for each Syngenta share in cash. That's equivalent to about Sfr480 for each share, the companies said, including a special dividend of Sfr5, which Syngenta shareholders will receive on top of an ordinary dividend of Sfr11. The Sfr480-per-share price values the equity at Sfr44.6 billion, based on 92.95 million Syngenta shares outstanding, and is about 22% more than Syngenta's closing price on Tuesday of Sfr392.30. The Monsanto offer that Syngenta spurned last summer, largely because of antitrust concerns, was worth Sfr470. The Deal's Lisa Allen has the details from New York.
