Bayer and Monsanto today announced that they signed a definitive merger agreement under which Bayer will acquire Monsanto for $128 per share in an all-cash transaction. Monsanto’s Board of Directors, Bayer’s Board of Management and Bayer’s Supervisory Board have unanimously approved the agreement. Based on Monsanto’s closing share price on May 9, 2016, the day before Bayer’s first written proposal to Monsanto, the offer represents a premium of 44 percent to that price.

“We are pleased to announce the combination of our two great organizations. This represents a major step forward for our Crop Science business and reinforces Bayer’s leadership position as a global innovation driven Life Science company with leadership positions in its core segments, delivering substantial value to shareholders, our customers, employees and society at large,” said Werner Baumann, CEO of Bayer AG.

“Today’s announcement is a testament to everything we’ve achieved and the value that we have created for our stakeholders at Monsanto. We believe that this combination with Bayer represents the most compelling value for our shareowners, with the most certainty through the all-cash consideration,” said Hugh Grant, Monsanto Chairman and CEO.

The combined agriculture business will have its global Seeds & Traits and North American commercial headquarters in St. Louis, Missouri, its global Crop Protection and overall Crop Science headquarters in Monheim, Germany, and an important presence in Durham, North Carolina, as well as many other locations throughout the U.S. and around the world. The Digital Farming activities for the combined business will be based in San Francisco, California.

“This combination is a great opportunity for employees, who will be at the forefront of innovation in our sector. This transaction also enhances Bayer’s strong commitment to the U.S., building on our 150-year history with operations across 25 states employing more than 12,000 people in the country. I am convinced that Monsanto will flourish as part of one of the most respected and trusted companies in the world,” said Baumann.

The companies will be holding a joint press conference at 8:30 central time.
