DuPont (DD) and Dow Chemical (DOW) announced the U.S. site structure for the companies intend to create following the planned separation of DowDuPont into three independent, publicly traded companies.

The corporate headquarters for the Agriculture company will be located in Wilmington, Delaware and will include the office of the CEO and key corporate support functions. Sites in Johnston, Iowa and Indianapolis, Indiana will serve as Global Business Centers, with leadership of business lines, business support functions, R&D, global supply chain, and sales and marketing capabilities concentrated in the two Midwest locations. In addition, the independent Agriculture company will feature DuPont in the company’s name, following completion of the corporate naming and branding process.

The structure of the Agriculture company was specifically developed to ensure the cost discipline and efficiency necessary to achieve the previously stated $1.3B in synergies, while establishing the strongest foundation possible for sustainable growth over the long term – which will in turn create long-term opportunities for the company’s global employee base and local communities. This structure enables the intended independent Agriculture company to consolidate DuPont’s and Dow’s complete Agriculture capabilities across seed and crop protection in three primary locations, which is integral to achieving the planned synergies. Prior to the intended separation into three independent companies, DowDuPont will be dual headquartered in Wilmington, Delaware and Midland, Michigan.

Both parties continue to plan for the closing of the transaction during the second half of 2016, subject to satisfying the necessary closing conditions including obtaining the required pre-merger regulatory approvals.
