MERGER WITH DUPONT

Effective August 31, 2017, Dow and DuPont completed the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 (the "Merger Agreement"), by and among the Company, DuPont, DowDuPont, Diamond Merger Sub, Inc. and Orion Merger Sub, Inc. Pursuant to the Merger Agreement, (i) Diamond Merger Sub, Inc. was merged with and into Dow, with Dow surviving the merger as a subsidiary of DowDuPont (the "Diamond Merger") and (ii) Orion Merger Sub, Inc. was merged with and into DuPont, with DuPont surviving the merger as a subsidiary of DowDuPont (the "Orion Merger" and, together with the Diamond Merger, the "Mergers"). Following the consummation of the Mergers, each of Dow and DuPont became subsidiaries of DowDuPont (collectively, the "Merger"). Following the Merger, Dow and DuPont intend to pursue, subject to certain customary conditions, including, among others, the effectiveness of registration statements filed with the SEC and approval by the board of directors of DowDuPont ("DowDuPont Board"), the separation of the combined company's agriculture, materials science and specialty products businesses through one or more tax-efficient transactions ("Intended Business Separations"). Additional information about the Merger is included in Current Reports on Form 8-K filed with the SEC on December 11, 2015, March 31, 2017, August 4, 2017 and September 1, 2017.

Upon completion of the Diamond Merger, each share of common stock, par value $2.50 per share, of Dow ("Dow Common Stock") (excluding any shares of Dow Common Stock that were held in treasury immediately prior to the effective time of the Diamond Merger, which were automatically canceled and retired for no consideration) was converted into the right to receive one fully paid and non-assessable share of common stock, par value $0.01 per share, of DowDuPont ("DowDuPont Common Stock"). As provided in the Merger Agreement, at the effective time of the Mergers, (i) all options, deferred stock, performance deferred stock and other equity awards relating to shares of Dow Common Stock outstanding immediately prior to the effective time of the Mergers were generally automatically converted into options and deferred stock and other equity awards relating to shares of DowDuPont Common Stock after giving effect to appropriate adjustments to reflect the Mergers and otherwise generally on the same terms and conditions as applied under the applicable plans and award agreements immediately prior to the effective time of the Mergers. See Note 20 for additional information on the conversion of the equity awards.

In the third quarter of 2017, as a result of the Diamond Merger and the Merger, the Company recorded a reduction in "Treasury stock" of $935 million, a reduction in "Common stock" of $3,107 million and an increase in "Additional paid in capital" of $2,172 million. At September 1, 2017, the Company has 100 shares of common stock issued and outstanding, par value $0.01 per share, owned solely by its parent, DowDuPont.

On August 31, 2017, following the Diamond Merger, Dow requested that the New York Stock Exchange ("NYSE") withdraw the shares of Dow Common Stock from listing on the NYSE and filed a Form 25 with the SEC to report that the shares of Dow Common Stock are no longer listed on the NYSE. The shares of Dow Common Stock were suspended from trading on the NYSE prior to the open of trading on September 1, 2017.

As a condition of the regulatory approval of the Merger, Dow and DuPont agreed to certain closing conditions, which are as follows:

• Dow divested its global Ethylene Acrylic Acid copolymers and ionomers business ("EAA Business") to SK Global Chemical Co., Ltd., on September 1, 2017, as part of a divestiture commitment given to the European Commission ("EC") in connection with the EC's conditional approval of the Merger granted on March 27, 2017. See Note 6 for additional information on this transaction.

• DuPont divested its Cereal Broadleaf Herbicides and Chewing Insecticides portfolios as well as its Crop Protection research and development ("R&D") pipeline and organization (excluding seed treatment, nematicides, late-stage R&D programs and certain personnel needed to support marketed products and R&D programs that will remain with DuPont) (collectively, the "DuPont Divested Assets") to FMC Corporation ("FMC") on November 1, 2017, as part of the EC's conditional approval granted on March 27, 2017. Also on November 1, 2017, DuPont completed its acquisition of FMC's Health and Nutrition business, excluding its Omega-3 products.

• On May 2, 2017, Dow and DuPont announced that China's Ministry of Commerce ("MOFCOM") granted conditional regulatory approval for the companies' proposed merger of equals which included commitments already made to the EC including DuPont's divestiture of the DuPont Divested Assets and Dow's divestiture of the EAA Business. In addition, Dow and DuPont made commitments related to the supply and distribution in China of certain herbicide and insecticide ingredients and formulations for rice crops for five years after the closing of the Merger.

• Dow divested a select portion of Dow AgroSciences' corn seed business in Brazil ("DAS Divested Ag Business") to CITIC Agri Fund on November 30, 2017. The divestiture was part of the commitment given to Brazil's Administrative Council for Economic Defense ("CADE") in connection with the CADE's conditional approval of the Merger granted on May 17, 2017, which was incremental to commitments already made to the EC, China and regulatory agencies in other jurisdictions. See Note 6 for additional information on this transaction.

• On June 15, 2017, Dow and DuPont announced that a proposed agreement had been reached with the Antitrust Division of the United States Department of Justice that permitted the companies to proceed with the proposed merger of equals transaction. The proposed agreement was consistent with commitments already made to the EC.

Intended Business Separations

In furtherance of the Intended Business Separations, Dow and DuPont are engaged in a series of internal reorganization and realignment steps (the “Internal Reorganization”) to realign their businesses into three subgroups: agriculture, materials science and specialty products. DowDuPont has also formed two wholly owned subsidiaries: Dow Holdings Inc. (“DHI”), to serve as a holding company for its materials science business, and Corteva, Inc. (“Corteva”), to serve as a holding company for its agriculture business. Following the separation and distribution of DHI, which is targeted to occur by April 1, 2019, DowDuPont, as the remaining company, which is referred to herein as “New DuPont,” will continue to hold the agriculture and specialty products businesses. New DuPont is then targeted to complete the separation and distribution of Corteva on June 1, 2019, resulting in New DuPont holding the specialty products businesses of DowDuPont. Following the distributions, DowDuPont will be known as DuPont.

As part of the Internal Reorganization, 1) the assets and liabilities of the materials science business will be transferred or conveyed to legal entities that then will be aligned under DHI, 2) the assets and liabilities of the agriculture business will be transferred or conveyed to legal entities that then will be aligned under Corteva, and 3) the assets and liabilities of the specialty products business will be transferred or conveyed to legal entities that then will be aligned with New DuPont. Following the Internal Reorganization, DowDuPont expects to distribute DHI and Corteva through separate, pro rata U.S. federal tax-free spin-offs in which DowDuPont stockholders, at such time, would receive shares of common stock of DHI and of Corteva.

Additional information is included in the Form 10 registration statements for the separation of DowDuPont's materials science business (filed as Dow Holdings Inc.) filed with the SEC on September 7, 2018, as amended on October 19, 2018 and November 19, 2018, and the agriculture business (filed as Corteva, Inc.) filed with the SEC on October 18, 2018, as amended on December 19, 2018.

ACQUISITIONS

Ownership Restructure of Dow Silicones

On June 1, 2016, the Company announced the closing of the transaction with Corning Incorporated ("Corning"), Dow Silicones and HS Upstate Inc., (“Splitco”), pursuant to which Corning exchanged with Dow Silicones its 50 percent equity interest in Dow Silicones for 100 percent of the stock of Splitco which held Corning's historical proportional interest in the Hemlock Semiconductor Group ("HSC Group") and approximately $4.8 billion in cash. As a result, Dow Silicones, previously a 50:50 joint venture between Dow and Corning, became a wholly owned subsidiary of Dow. In connection with the ownership restructure, on May 31, 2016, Dow Silicones incurred $4.5 billion of indebtedness in order to fund the contribution of cash to Splitco. See Notes 12, 15 and 23 for additional information.

At June 1, 2016, the Company's equity interest in Dow Silicones, excluding the HSC Group, was $1,968 million. This equity interest was remeasured to fair value. As a result, the Company recognized a non-taxable gain of $2,445 million in the second quarter of 2016, net of closing costs and other comprehensive loss related to the Company's interest in Dow Silicones. The gain was included in "Sundry income (expense) - net" in the consolidated statements of income. The Company recognized a tax benefit of $141 million on the ownership restructure in the second quarter of 2016, primarily due to the reassessment of a previously recognized deferred tax liability related to the basis difference in the Company’s investment in Dow Silicones. In addition, the fair value step-up of "Inventories" acquired was an increase of $317 million, which was expensed to "Cost of sales" over a three-month period beginning on June 1, 2016. In 2018, the Company recorded a pretax loss of $47 million for post-closing adjustments related to the Dow Silicones ownership restructure, included in "Sundry income (expense) - net" in the consolidated statements of income.

The ownership restructure resulted in the recognition of $3,229 million of "Goodwill" which was not deductible for tax purposes. Goodwill largely consisted of expected synergies resulting from the ownership restructure. Cost synergies were achieved through a combination of workforce consolidation and savings from actions such as harmonizing energy contracts at large sites, optimizing warehouse and logistics footprints, implementing materials and maintenance best practices, combining information technology service structures and leveraging existing R&D knowledge management systems.

The Company evaluated the disclosure requirements under ASC 805 "Business Combinations" and determined the ownership restructure was not considered a material business combination for purposes of disclosing the revenue and earnings of Dow Silicones since the date of the ownership restructure as well as supplemental pro forma information.

Beginning in June 2016, the results of Dow Silicones, excluding the HSC Group, were fully consolidated in the Company’s consolidated statements of income. Prior to June 2016, the Company’s 50 percent share of Dow Silicones’ results of operations was reported in “Equity in earnings of nonconsolidated affiliates” in the consolidated statements of income. The results of the HSC Group continue to be treated as an equity method investment and reported as “Equity in earnings of nonconsolidated affiliates” in the consolidated statements of income.
