Joint DuPont and Dow Integration Planning Team Meets in Wilmington

Leaders from Dow traveled to Wilmington last week to launch the newly formed Integration Planning Teams, one composed of DuPont executives and another of Dow executives. Using their expertise and experience, they rolled up their sleeves to start working out the details of what is one of the largest proposed corporate mergers in history.

Their task is to make all planning aspects of the transition as smooth as possible.  From fulfilling all of the regulatory requirements to capturing the $3 billion in synergies between Dow and DuPont, the teams will leave no detail to chance.

DuPont CFO Nick Fanandakis kicked off the meeting, laying out the structure and processes for the nearly 60 leaders who are driving this work. Under the guidance of an Executive Steering Team — sponsored jointly by DuPont Chair & CEO Ed Breen and Dow President, Chairman and CEO Andrew Liveris — three core work streams were defined:

·      Close and Stand Up the Merged Company

·      Identify and Capture Synergies

·      Stand Up Three Independent Operating Companies (Agriculture Co., Materials Co., and Specialty Products Co.)

“It was energizing for everyone to meet face to face and begin the important work of integration planning,” said Stacy Fox, SVP and General Counsel, and DuPont lead for the Close and Stand Up MergeCo work stream. “The possibilities created by Dow and DuPont combining, and the enormous opportunities that the three proposed businesses offer, really start to come to life the more the teams get to know each other.”

Inside the Oval will provide future progress updates on the teams as they become available.

Cautionary Notes on Forward Looking Statements

This communication contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In this context, forward-looking statements often address expected future business and financial performance and financial condition, and often contain words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “see,” “will,” “would,” “target,” similar expressions, and variations or negatives of these words. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about the consummation of the proposed transaction and the anticipated benefits thereof. These and

other forward-looking statements, including the failure to consummate the proposed transaction or to make or take any filing or other action required to consummate such transaction on a timely matter or at all, are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially from those expressed in any forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to, (i) the completion of the proposed transaction on anticipated terms and timing, including obtaining shareholder and regulatory approvals, anticipated tax treatment, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, future prospects, business and management strategies for the management, expansion and growth of the new combined company’s operations and other conditions to the completion of the merger, (ii) the ability of Dow and DuPont to integrate the business successfully and to achieve anticipated synergies, risks and costs and pursuit and/or implementation of the potential separation, including timing anticipated, any changes to the configuration of businesses included in the potential separation if implemented, (iii) potential litigation relating to the proposed transaction that could be instituted against Dow, DuPont or their respective directors, (iv) the risk that disruptions from the proposed transaction will harm Dow’s or DuPont’s business, including current plans and operations, (v) the ability of Dow or DuPont to retain and hire key personnel, (vi) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the merger, (vii) uncertainty as to the long-term value of Diamond-Orion HoldCo common stock, (viii) continued availability of capital and financing and rating agency actions, (ix) legislative, regulatory and economic developments and (x) unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as management’s response to any of the aforementioned factors. These risks, as well as other risks associated with the proposed merger, will be more fully discussed in the joint proxy statement/prospectus that will be included in the registration statement on Form S-4 that will be filed with the SEC in connection with the proposed merger. While the list of factors presented here is, and the list of factors to be presented in the registration statement on Form S-4 are, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on Dow’s or DuPont’s consolidated financial condition, results of operations, credit rating or liquidity. Neither Dow nor DuPont assumes any obligation to publicly provide revisions or updates to any forward looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws.
