Organic1 sales increased 16% in the same period with double-digit gains in all regions. • Seed net sales grew 5% and organic1 sales increased 8% year over year, with notable gains in EMEA2 as well as North America2 soybeans, partially offset by the reduction of corn acres and canola volumes in North America2. Price was up 7% globally, led by continued execution on the Company’s price for value strategy and recovery of higher input costs. • Crop Protection net sales grew 22% and organic1 sales increased 26%, with broad-based gains across all regions. Volume gains were driven by continued penetration of new products, including EnlistTM and ArylexTM herbicides and OnmiraTM fungicide.

News Release 3Q 2022 2 _ Company Updates Company Signs Agreement to Acquire Biological Leader Symborg • During the quarter, the Company announced it had signed a definitive agreement to acquire Symborg, a leader in microbiological technologies based in Murcia, Spain. • The Company first collaborated with Symborg to scale up and bring farmers Utrisha™ N and BlueN™ nutrient efficiency optimizer as part of a distribution agreement between the two companies. • This transaction continues the Company’s commitment to build a more differentiated and sustainably advantaged portfolio that provides cost-effective solutions for farmers. Company Initiates First Significant Steps Towards Portfolio Simplification • During the quarter, the Company made a business decision to exit commodity glyphosate products, reflecting our commitment to disciplined and strategic portfolio management – prioritizing core markets and crops to optimize resource allocation and drive long-term value creation. • This decision allows the Company to simplify operations and focus investments on delivering greater value to growers through more differentiated and sustainably advantaged solutions. • As a result of this decision, the Company expects an approximate $300 million headwind to net sales related to commodity glyphosate products in 2023. EnlistTM System Crosses $1B in Net Sales • The Company delivered approximately $1.1 billion in sales for the EnlistTM system during the nine months ended September 30, 2022, an increase of nearly 80% versus the same period last year. • The Company expects 2023 Enlist E3TM4 U.S. market penetration in the mid 50% range, representing approximately 70% of Corteva’s lineup – a notable accomplishment considering this technology has only been in the market for 3 seasons. The percentage of EnlistTM with proprietary Corteva germplasm is expected to reach approximately 65%. “Corteva delivered another solid quarter of sales and Operating EBITDA growth, reflecting focused global execution and strong customer demand. We continue to make progress on portfolio actions, including our agreement to acquire Symborg, a leading biologicals business, and our decision to exit commodity glyphosate products. These actions demonstrate our commitment to deliver increased value to farmers through differentiated technologies and contribute to a more sustainable global food system. Looking ahead to 2023, we expect the near-term operating environment to remain dynamic. While the outlook for ag fundamentals is strong, macroeconomic pressures are expected to continue, including currency and inflation headwinds. In this environment, we remain focused on executing our strategic plan and serving customers. We believe farmers will continue to prioritize top-tier technologies to increase productivity on the farm. We are in a unique position to provide industry-leading innovative solutions that will accelerate our performance and growth.” Chuck Magro Chief Executive Officer

News Release 3Q 2022 4 Seed Summary Seed net sales were $862 million in the third quarter of 2022, up from $738 million in the third quarter of 2021. The sales increase was driven by an 11% increase in volumes and a 10% increase in price, partially offset by a 4% unfavorable currency impact. Higher volumes were driven by higher other oilseed sales in India, as well as a later start to the planting season in North America, which shifted some corn and soybean sales into the third quarter. Price gains were driven by strong execution globally, as farmers prioritize yield to help offset inflation. Unfavorable currency impacts were led by the South African Rand and the Euro. Segment Operating EBITDA was $(224) million in the third quarter of 2022, down 3% from the third quarter of 2021. Price execution, volume gains, and ongoing cost and productivity actions were more than offset by higher input and freight costs, including commodity costs. Segment operating EBITDA margin improved by approximately 340 basis points versus the prior-year period. 3Q 3Q % % ($ in millions, except where noted) 2022 2021 Change Organic1 Change North America $218 $168 30% 31% EMEA $157 $153 3% 16% Latin America $383 $334 15% 15% Asia Pacific $104 $83 25% 33% Total 3Q Seed Net Sales $862 $738 17% 21% 3Q Seed Operating EBITDA $(224) $(217) (3)% N/A Seed net sales were $7.3 billion for the first nine months of 2022, up from approximately $7.0 billion for the first nine months of 2021. The sales increase was driven by a 7% increase in price and a 1% increase in volumes. This gain was partially offset by a 3% unfavorable currency impact. The increase in price was driven by strong execution globally, led by North America and EMEA, with global corn and soybean prices up 7% and 10%, respectively. The increase in volume was driven by gains in EMEA as well as North America soybeans, partially offset by reduced corn acres in North America and supply constraints in North America canola and Latin America corn. Unfavorable currency impacts were led by the Turkish Lira and the Euro. Segment Operating EBITDA was $1.6 billion for the first nine months of 2022, up 4% from the same period last year.

The increase in volume was driven by continued penetration of new products, including EnlistTM herbicide and ZorvecTM fungicide. Unfavorable currency impacts were led by the Euro. The portfolio impact was driven by a divestiture in Asia Pacific. Segment Operating EBITDA was $352 million in the third quarter of 2022, up 71% from the third quarter of 2021.

News Release 3Q 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 farmers to prioritize technology to maximize return. As a result, the Company affirmed full year 2022 net sales guidance3 of $17.2 billion to $17.5 billion, which at the mid-point represents expected net sales growth of 11% for the year. The Company increased the mid-point of its Operating EBITDA1 guidance, and now expects it to be in the range of $3.0 billion to $3.1 billion, which at the mid-point represents expected Operating EBITDA1 growth of 18% 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.

News Release 3Q 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 EBITDA margin, 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. 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 (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. 11/03/2022 Media Contact Kris Allen +1 403-483-5205 kris.allen@corteva.com Investor Contact Kim Booth +1 302-485-3190 kimberly.a.booth@corteva.com
