Safe Harbor Regarding Forward-Looking Statements

Forward-Looking Statements

This presentation contains certain estimates and 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", "guidance", 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 DowDuPont, are forward-looking statements.

Forward-looking statements and other estimates are based on certain assumptions and expectations of future events which may not be accurate or realized. Forward-looking statements and other estimates 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) failure to obtain or maintain the necessary regulatory approvals for some Corteva's

products; (ii) failure to successfully develop and commercialize Corteva's pipeline; (iii) effect of the degree of public understanding and acceptance or perceived public acceptance of Corteva's biotechnology and other agricultural products; (iv) effect of changes in agricultural and related policies of governments and international organizations; (v) effect of competition and consolidation in Corteva's industry; (vi) effect of competition from manufacturers of generic products; (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 climate change and unpredictable seasonal and weather factors; (ix) risks related to oil and commodity markets; (x) competitor's establishment of an intermediary platform for distribution of Corteva's products; (xi) impact of Corteva's dependence on third parties with respect to certain of its raw materials or licenses and commercialization; (xii) effect of industrial espionage and other disruptions to Corteva's supply chain, information technology or network systems; (xiii) effect of volatility in Corteva's input costs; (xiv) failure to realize the anticipated benefits of the internal reorganizations taken by DowDuPont in connection with the spin-off of Corteva and other cost savings initiatives; (xv) failure to raise capital through the capital markets or short-term borrowings on terms acceptable to Corteva; (xvi) failure of Corteva's customers to pay their debts to Corteva, including customer financing programs; (xvii) increases in pension and other

post-employment benefit plan funding obligations; (xviii) risks related to the indemnification obligations of legacy EID liabilities in connection with the separation of Corteva; (xix) effect of compliance with laws and requirements and adverse judgments on litigation; (xx) risks related to Corteva's global operations; (xxi) failure to effectively manage acquisitions, divestitures, alliances and other portfolio actions; (xxii) risks related to COVID-19; (xxiii) risks related to activist stockholders; (xxiv) Corteva's intellectual property rights or defend against intellectual property claims asserted by others; (xxv) effect of counterfeit products; (xxvi) Corteva's dependence on intellectual property cross-license agreements; (xxvii) other risks related to the Separation from DowDuPont; (xxviii) risks related to the Biden executive order Promoting Competition in the American Economy; and (xxix) risks associated with our CEO transition.

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 or other estimate, 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 or other estimate, 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 or other estimates is included in the "Risk Factors" section of Corteva's Annual Report on Form 10-K, as modified by subsequent Quarterly Reports on Forms 10-Q and Current Reports on Form 8-K.

A Reminder About Non-GAAP Financial Measures

Regulation G (Non-GAAP Financial Measures)

This presentation includes information that does not conform to U.S. GAAP and are considered non-GAAP measures. These performance measures may include organic sales, organic growth (including by segment and region), operating EBITDA, operating EBITDA margin, operating earnings per share, and base tax rate. Management uses these measures internally for planning and forecasting, including allocating resources and evaluating incentive compensation. Management believes that these non-GAAP measures reflect the ongoing performance of the Company during the periods presented and provide relevant and meaningful information to investors as they provide insight with respect to ongoing operating results of the Company and a helpful comparison of year over year results.

Corteva is not able to reconcile its forward-lookingnon-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 slide 28. Beginning January 1, 2020, the company presents accelerated prepaid royalty amortization expense as a significant item. Accelerated prepaid royalty amortization represents the noncash charge associated with the recognition of upfront payments made to Monsanto in connection with the Company's non-exclusive license in the United States and Canada for Monsanto's Genuity® Roundup Ready 2 Yield® Roundup Ready 2 Xtend® herbicide tolerance traits. During the five-yearramp-up period of Enlist E3TM, Corteva is expected to significantly reduce the volume of products with the Roundup Ready 2 Yield® and Roundup Ready 2 Xtend® herbicide tolerance traits beginning in 2021, with expected minimal use of the trait platform after the completion of the ramp-up. Additionally, on February 1, 2021, Corteva approved restructuring actions designed to right-size and optimize footprint and organizational structure according to the business needs in each region with the focus on driving continued cost improvement and productivity. The restructuring actions are expected to be substantially complete in 2021.

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, foreign exchange gains (losses), net, and net unrealized gain or loss from mark-to-market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting, 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, the after-tax impact of amortization expense associated with intangible assets existing as of the Separation from DowDuPont, and the after-tax impact of net unrealized gain or loss from mark-to-market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting. 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. Net unrealized gain or loss from mark-to-market activity for certain foreign currency derivative instruments that do not qualify for hedge accounting represents the non-cash net gain (loss) from changes in fair value of certain undesignated foreign currency derivative contracts. Upon settlement, which is within the same calendar year of execution of the contract, the realized gain (loss) from the changes in fair value of the non-qualified foreign currency derivative contracts will be reported in the relevant non-GAAP financial measures, allowing quarterly results to reflect the economic effects of the foreign currency derivative contracts without the resulting unrealized mark to fair value volatility. Base tax rate is defined as the effective tax rate excluding the impacts of foreign exchange gains (losses), net, non-operating benefits, net, amortization of intangibles as of the Separation from DowDuPont, and significant items (including goodwill impairment charges).

The Company also uses Free Cash Flow as non-GAAP measure to evaluate and discuss its liquidity position and ability to generate cash. Free Cash Flow is defined as cash from operating activities, less capital expenditures. We believe that Free Cash Flow provides investors with meaningful information regarding the Company's ongoing ability to generate cash through core operations, and our ability to service our indebtedness, pay dividends (when declared), make share repurchases, and meet our ongoing cash needs for our operations.

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 or liquidity, as applicable. 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 their most directly attributable U.S. GAAP measure are provided on slides 26 - 34 of this presentation.
