News Release 2Q/1H 2022 2 _ Company Updates Company Announces Completion of Strategic Portfolio Reviews • In connection with its previously announced business realignment, the Company completed strategic portfolio reviews, aimed at refining the Company’s strategy and accelerating short-term and long-term margin growth. • The outcome of this analysis is the Company’s plan to exit non-strategic geographies and product lines while emphasizing its core markets and crops, representing over 95% of its current total net sales and 99% of its current total Operating EBITDA1. • These portfolio decisions will position the Company to focus investment on delivering greater value to growers through more differentiated and sustainably advantaged solutions, leveraging its pipeline to drive advancements in global food security and climate change. • The Company is also right-sizing and optimizing its cost structure to enable greater agility and accountability for the performance of its two business units, Seed and Crop Protection. • As a result, the Company expects to record total restructuring and other charges of approximately $400 million through the second quarter of 2023, roughly half of which represents cash payments. • In the second quarter of 2022, the Company recorded $68 million of restructuring and other charges, of which $45 million related to the Company’s previously announced exit from Russia. • As a result of these actions, the Company expects to achieve more than $200 million in run-rate savings by 2025. • Additional information on the outcome of the strategic portfolio reviews will be shared on September 13th at the Company’s 2022 Investor Day. EnlistTM System Accelerates Market Penetration for 2022 • The Company delivered approximately $980 million in sales for the EnlistTM system during the first half, an increase of more than 60% versus the first half of 2021. • The Company raised its Enlist E3TM4 2022 market penetration outlook to greater than 45% of U.S. soybean acres, up from greater than 40% expected previously. • The Company estimates that greater than 80% of Enlist E3TM4 acres will receive an EnlistTM herbicide application, reflecting strong market demand and positive grower feedback on the ease and simplicity of the system. “Corteva delivered an impressive first half with double-digit sales and Operating EBITDA growth and margin expansion, reflecting strong customer demand and focused execution amidst dynamic market conditions. We also continue to take actions to accelerate performance, including the completion of strategic portfolio reviews aimed at refining our strategy, driving operational execution, and making disciplined investment decisions in innovation and technology to deliver increased value to farmers and contribute to a more sustainable global food system. We believe that we are well-positioned to continue to adapt and execute in a challenging operating environment. Our strong first half momentum and robust market fundamentals have given us confidence to raise our guidance for the year.” Chuck Magro Chief Executive Officer

News Release 2Q/1H 2022 4 Seed Summary Seed net sales were $3.9 billion in the second quarter of 2022, up from approximately $3.8 billion in the second quarter of 2021. The sales increase was driven by a 7% increase in price, partially offset by a 1% decline in volume and a 2% unfavorable currency impact. The increase in price was driven by strong execution, with global corn and soybean prices up 6% and 8%, respectively.

The sales increase was driven by a 14% increase in volume and a 14% increase in price. These gains were partially offset by a 2% unfavorable currency impact and a 1% unfavorable portfolio impact.

News Release 2Q/1H 2022 6 2022 Updated Guidance The outlook for agriculture remains robust despite recent commodity price volatility. The Company expects record demand for grain and oilseeds in 2022, which should support commodity prices as ending stocks remain under pressure. Grower balance sheets and income levels remain healthy despite increased input costs for fuel and fertilizer, leading customers to prioritize technology to maximize return. As a result, the Company updated its previously provided guidance3 for the full year 2022 – increasing sales and earnings expectations for this period. Corteva expects net sales in the range of $17.2 billion to $17.5 billion, which at the mid-point represents expected net sales growth of 11% for the year. Operating EBITDA1 is expected to be in the range of $2.95 billion to $3.10 billion, which at the mid-point represents expected Operating EBITDA1 growth of 17% for the year. Operating EPS1 is expected to be in the range of $2.45 to $2.60 per share. The Company is not able to reconcile its forward-looking non-GAAP financial measures to its most comparable U.S. GAAP financial measures, as it is unable to predict with reasonable certainty items outside of its control, such as Significant Items, without unreasonable effort. Second Quarter Conference Call The Company will host a live webcast of its second quarter and first half 2022 earnings conference call with investors to discuss its results and outlook tomorrow, August 5, 2022, at 9:00 a.m. ET.

News Release 2Q/1H 2022 7 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 may include organic sales, organic growth (including by segment and region), operating EBITDA, operating earnings (loss) per share, and base income 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 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 A-5 of the Financial Statement Schedules. Corteva is not able to reconcile its forward-looking non-GAAP financial measures to its 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 A-10 of the Financial Statement Schedules. 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-year ramp-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, in connection with the Company’s shift to a global business unit model, the Company has assessed its business priorities and operational structure to maximize the customer experience and deliver on growth and earnings potential. As a result of this assessment, the company has committed to restructuring actions that, combined with the impact of the company’s separate announcement to withdraw from Russia and stop production and business activities (“Russia Exit”) (collectively the “2022 Restructuring Actions”), have resulted in expected total pre-tax restructuring and other charges of approximately $350 million to $420 million. The restructuring actions associated with these charges are expected to be substantially complete in 2023. Organic sales is defined as price and volume and excludes currency and portfolio impacts. Operating EBITDA is defined as earnings (loss) (i.e., income (loss) from continuing operations before income taxes) before interest, depreciation, amortization, non- operating benefits (costs), foreign exchange gains (losses), 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. Non-operating (benefits) costs consists of non-operating pension and other post-employment benefit (OPEB) benefits (costs), tax indemnification adjustments, and 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 earnings (loss) per share is defined as “earnings (loss) per common share from continuing operations - diluted” excluding the after-tax impact of significant items, the after tax impact of non-operating benefits (costs), 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 income tax rate is defined as the effective tax rate excluding the impacts of foreign exchange gains (losses), non-operating benefits (costs), amortization of intangibles (existing as of the Separation), mark-to- market gains (losses) on certain foreign currency contracts not designated as hedges, and significant items. ® TM Corteva Agriscience and its affiliated companies. 08/04/2022 Media Contact Gregg Schmidt +1 302-485-3260 gregg.m.schmidt@corteva.com Investor Contact Kim Booth +1 302-485-3704 kimberly.a.booth@corteva.com
