Safe Harbor Regarding Forward-Looking Statements Forward-Looking Statements This presentation contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A of the Securities Act of 1933, as amended, which are intended to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and may be identified by their use of words like “plans,” “expects,” “will,” “anticipates,” “believes,” “intends,” “projects,” “estimates” or other words of similar meaning. All statements that address expectations or projections about the future, including statements about Corteva’s strategy for growth, product development, regulatory approval, market position, anticipated benefits of recent acquisitions, timing of anticipated benefits from restructuring actions, outcome of contingencies, such as litigation and environmental matters, expenditures, and financial results, as well as expected benefits from, the separation of Corteva from DuPont, are forward-looking statements. Forward-looking statements are based on certain assumptions and expectations of future events which may not be accurate or realized. Forward-looking statements also involve risks and uncertainties, many of which are beyond Corteva’s control. While the list of factors presented below is 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 Corteva’s business, results of operations and financial condition. Some of the important factors that could cause Corteva’s actual results to differ materially from those projected in any such forward-looking statements include: (i) effect of competition and consolidation in Corteva’s industry; (ii) failure to successfully develop and commercialize Corteva’s pipeline; (iii) failure to obtain or maintain the necessary regulatory approvals for some Corteva’s products; (iv) failure to enforce Corteva’s intellectual property rights or defend against intellectual property claims asserted by others; (v) effect of competition from manufacturers of generic products; (vi) impact of Corteva’s dependence on third parties with respect to certain of its raw materials or licenses and commercialization; (vii) costs of complying with evolving regulatory requirements and the effect of actual or alleged violations of environmental laws or permit requirements; (viii) effect of the degree of public understanding and acceptance or perceived public acceptance of Corteva’s biotechnology and other agricultural products; (ix) effect of changes in agricultural and related policies of governments and international organizations; (x) effect of disruptions to Corteva’s supply chain, information technology or network systems; (xi) competitor’s establishment of an intermediary platform for distribution of Corteva’s products; (xii) effect of volatility in Corteva’s input costs; (xiii) failure to raise capital through the capital markets or short-term borrowings on terms acceptable to Corteva; (xiv) failure of Corteva’s customers to pay their debts to Corteva, including customer financing programs; (xv) failure to realize the anticipated benefits of the internal reorganizations taken by DowDuPont in connection with the spin-off of Corteva; (xvi) failure to benefit from significant cost synergies and risks related to the indemnification obligations of legacy DuPont liabilities in connection with the separation of Corteva; (xvii) increases in pension and other post-employment benefit plan funding obligations; (xviii) effect of compliance with environmental laws and requirements and adverse judgments on litigation; (xix) risks related to Corteva’s global operations; (xx) effect of climate change and unpredictable seasonal and weather factors; (xxi) effect of counterfeit products; (xxii) failure to effectively manage acquisitions, divestitures, alliances and other portfolio actions; and (xxiii) risks related to the discontinuation of LIBOR. Additionally, there may be other risks and uncertainties that Corteva is unable to currently identify or that Corteva does not currently expect to have a material impact on its business. Where, in any forward-looking statement, an expectation or belief as to future results or events is expressed, such expectation or belief is based on the current plans and expectations of Corteva’s management and expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the expectation or belief will result or be achieved or accomplished. Corteva disclaims and does not undertake any obligation to update or revise any forward-looking statement, except as required by applicable law. A detailed discussion of some of the significant risks and uncertainties which may cause results and events to differ materially from such forward-looking statements is included in the “Risk Factors” section of Exhibit 99.1 of Amendment No. 4 to Corteva’s Registration Statement on Form 10 and Corteva’s Quarterly Report on Form 10-Q for the period ended June 30, 2019, as modified by subsequent reports on Form 10-Q and Current Reports on Form 8-K. 2

A Reminder About Non-GAAP Financial Measures and Pro Forma Financial Information Corteva Unaudited Pro Forma Financial Information In order to provide the most meaningful comparison of results of operations, supplemental unaudited pro forma financial information for the first quarter of 2019 and prior has been included in this presentation. This presentation presents the pro forma results of Corteva, after giving effect to events that are (1) directly attributable to the merger of DuPont and Dow, debt retirement transactions related to paying off or retiring portions of Historical DuPont’s existing debt liabilities, and the separation and distribution to DowDuPont stockholders of all the outstanding shares of Corteva common stock; (2) factually supportable and (3) with respect to the pro forma statements of income, expected to have a continuing impact on the consolidated results. Refer to Corteva’s Form 10 registration statement filed on May 6, 2019, which can be found on the investors section of the Corteva website, for further details on the above transactions. The pro forma financial statements were prepared in accordance with Article 11 of Regulation S-X, and are presented for informational purposes only, and do not purport to represent what the results of operations would have been had the above actually occurred on the dates indicated, nor do they purport to project the results of operations for any future period or as of any future date. Regulation G (Non-GAAP Financial Measures) This earnings release includes information that does not conform to U.S. GAAP and are considered non-GAAP measures. These measures include organic sales, operating EBITDA, pro forma operating EBITDA, operating EBITDA margin, pro forma operating EBITDA margin, operating earnings per share, pro forma operating earnings per share, base tax rate, and pro forma base tax rate. Management believes that these non-GAAP measures best reflect the ongoing performance of the Company during the periods presented and provide more relevant and meaningful information to investors as they provide insight with respect to ongoing operating results of the Company and a more useful comparison of year over year results. These non-GAAP measures supplement the Company's U.S. GAAP disclosures and should not be viewed as an alternative to U.S. GAAP measures of performance. Furthermore, such non-GAAP measures may not be consistent with similar measures provided or used by other companies. Reconciliations for these non-GAAP measures to U.S. GAAP are provided in the Selected Financial Information and Non-GAAP Measures starting on page 5 of the Financial Statement Schedules. For first quarter 2019 and prior year, these non-GAAP measures are being reconciled to a pro forma GAAP financial measure prepared and presented in accordance with Article 11 of Regulation S-X. Reconciliations for these non-GAAP measures to their most directly attributable U.S. GAAP measure are provided on slides 16 - 22 of this presentation. Corteva is not able to reconcile its forward-looking non-GAAP financial measures to their most comparable U.S. GAAP financial measures, as it is unable to predict with reasonable certainty items outside of the company’s control, such as Significant Items, without unreasonable effort. For Significant Items reported in the periods presented, refer to page 8 of the Financial Statement Schedules. Organic sales is defined as price and volume and excludes currency and portfolio impacts. Operating EBITDA is defined as earnings (i.e., income from continuing operations before income taxes) before interest, depreciation, amortization, non-operating benefits, net and foreign exchange gains (losses), excluding the impact of significant items (including goodwill impairment charges). Non-operating benefits, net consists of non-operating pension and other post-employment benefit (OPEB) credits, tax indemnification adjustments, environmental remediation and legal costs associated with legacy businesses and sites of Historical DuPont. Tax indemnification adjustments relate to changes in indemnification balances, as a result of the application of the terms of the Tax Matters Agreement, between Corteva and Dow and/or DuPont that are recorded by the company as pre-tax income or expense. Operating EBITDA margin is defined as Operating EBITDA as a percentage of net sales. Operating earnings per share are defined as "Earnings per common share from continuing operations - diluted" excluding the after-tax impact of significant items (including goodwill impairment charges), the after-tax impact of non-operating benefits, net, and the after-tax impact of amortization expense associated with intangible assets existing as of the Separation from DowDuPont. Although amortization of the Company's intangible assets is excluded from these non-GAAP measures, management believes it is important for investors to understand that such intangible assets contribute to revenue generation. Amortization of intangible assets that relate to past acquisitions will recur in future periods until such intangible assets have been fully amortized. Any future acquisitions may result in amortization of additional intangible assets. Base tax rate is defined as the effective tax rate excluding the impacts of foreign exchange gains (losses), non-operating benefits, net, amortization of intangibles as of the Separation from DowDuPont, and significant items (including goodwill impairment charges). All periods for the first quarter of 2019 and prior are on a pro forma basis as discussed above in the paragraph ‘Corteva Unaudited Pro Forma Financial Information’. 3

Operating earnings is defined as net income from continuing operations attributable to Corteva excluding the after-tax impact of significant items (including goodwill impairment charges), non-operating benefits - net, and amortization of intangible assets (as of Separation). Although amortization of intangible assets (as of Separation) is excluded from these non-GAAP measures, management believes it is important for investors to understand that such intangible assets contribute to revenue generation. Amortization of intangible assets that relate to past acquisitions will recur in future periods until such intangible assets have been fully amortized. Any future acquisitions may result in amortization of additional intangible assets 21
