Bayer and Monsanto 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% 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, Chairman and CEO of Monsanto.

Bank of America Merrill Lynch and Credit Suisse are acting as lead financial advisors and structuring banks to Bayer in addition to providing committed financing for the transaction; Rothschild has been retained as an additional financial advisor to Bayer. Bayer’s legal advisors are Sullivan & Cromwell LLP (M&A) and Allen & Overy LLP (Financing).

Morgan Stanley & Co. and Ducera Partners are acting as financial advisors, and Wachtell, Lipton, Rosen & Katz is acting as legal advisor to Monsanto.
