(NYSE: CTVA) (“Corteva” or the “Company”) today reported financial results for the three months ended March 31, 2023. 1Q 2023 Results Overview Net Sales Income from Cont. Ops (After Tax) EPS GAAP $4.88B $607M $0.84 vs. 1Q 2022 +6% +5% +6% Organic1 Sales Operating EBITDA1 Operating EPS1 NON-GAAP $5.06B $1.23B $1.16 vs. 1Q 2022 +10% +18% +20% First Quarter 2023 Highlights • First quarter 2023 net sales rose 6% versus prior year with gains in both segments. Organic1 sales increased 10% in the same period, led by EMEA2 and North America2. • Seed net sales grew 7% and organic1 sales increased 10%. Price gains were led by continued execution on the Company’s price for value strategy and recovery of higher input costs. Volume declines were driven by a shortened Safrinha season, supply constraints in Latin America, and the exit from Russia. • Crop Protection net sales grew 5% and organic1 sales increased 10%, led by value capture in EMEA. Price gains reflected strong execution in response to cost inflation. Volume gains from continued penetration of new products, including EnlistTM and ArylexTM herbicides, were more than offset by product exits and delays in Latin America and APAC due to weather. • GAAP income and earnings per share (EPS) from continuing operations were $607 million and $0.84 per share for the first quarter 2023, respectively. Operating EBITDA1 and Operating EPS1 were $1.23 billion and $1.16 per share, respectively. Strong price execution, product mix, and productivity actions more than offset inflation and currency headwinds. • The Company increased full-year 2023 guidance3 to include the impact of the Biologicals acquisitions and expects net sales in the range of $18.6 billion to $18.9 billion. Operating EBITDA1 is expected to be in the range of $3.55 billion to $3.75 billion. Operating EPS1 is expected to be in the range of $2.80 to $3.00 per share. 1.

News Release 1Q 2023 2 Company Updates New Product Launches During the Quarter Reinforce Value of Innovation Pipeline • The Company announced plans for the commercial launch of Optimum® GLY Canola - a new, proprietary glyphosate trait technology intended to deliver enhanced weed control and a wider window of herbicide application, compared to first- generation glyphosate trait technology – so farmers have more choices and flexibility for effective weed management. • The Company also announced the commercial launch of VorceedTM Enlist® Corn, which combines three modes of action for above-ground insect protection and three modes of action for below-ground insect protection including RNAi technology. It also includes tolerance to four herbicides – glyphosate, glufosinate, 2,4-D choline and FOPs – to help improve resistant weed management. • Finally, the Company announced the commercial launch of AdaveltTM Active - a novel fungicide with a new mode of action that protects against a wide range of diseases that can impact crop yields. The Company received product registrations in Australia, Canada, and South Korea, and plans to offer AdaveltTM Active in additional countries in the future, pending regulatory approvals. Company Acquires Symborg and Stoller, Two Leading Biologicals Companies • During the quarter, the Company acquired Symborg, an expert in microbiological technologies based in Murcia, Spain; and Stoller, one of the largest independent companies in the Biologicals industry with an expertise in plant health and nutrition, based in Houston, Texas. • These investments reinforce the Company’s commitment to providing farmers with sustainable tools that deliver optionality, enhanced value, and increased productivity. • These acquisitions, when combined with its internal innovation capabilities, cement Corteva’s Biologicals business as one of the largest in the world, with a platform positioned to accelerate growth within the rapidly expanding biologicals market. Company Announces Collaborations to Bring Sustainable Solutions to Farmers • During the quarter, the Company announced a multi-year collaboration with Bunge to develop and commercialize new soybean varieties with greater protein content, optimized amino acid profiles and lower levels of anti-nutritional factors for the animal feed industry. In-line with Corteva’s commitment to delivering sustainable innovation to its customers, these products present a potential new value stream opportunity for farmers while giving feed compounders a more nutritious option to reduce their use of synthetic additives, lower costs, and shrink their carbon footprint. • Separately, the Company announced a commercial collaboration with Bunge and Chevron U.S.A. Inc., a subsidiary of Chevron Corporation, to introduce proprietary winter canola hybrids intended to increase availability of plant-based oil feedstocks for the biofuel market. As part of a new double crop system in the southern U.S., this innovation will deliver solutions for farmers to increase productivity and income on their acres, while contributing to market expansion for lower carbon fuel options. Further, winter canola can act as a cover crop to enhance soil health and make farming practices even more sustainable. “Corteva delivered a solid start to 2023, reflecting focused execution coupled with continued demand for our innovative technology solutions. Our strategic actions to focus our portfolio in areas where we deliver differentiated value to customers are translating into accelerated growth in new product sales, continued margin expansion, and higher quality earnings. Ag fundamentals remain constructive as tight global grain supply continues to put pressure on ending stocks, keeping crop prices above historical averages and farm income levels healthy. We also see customer buying behaviors beginning to normalize as supply chain reliability improves. We are on track to deliver our 2025 financial objectives as our leading R&D organization continues to invest in new and differentiated technologies to drive a more sustainable global food and fuel system.” Chuck Magro Chief Executive Officer

News Release 1Q 2023 3 Seed Summary Seed net sales were $2.7 billion in the first quarter of 2023, up from $2.5 billion in the first quarter of 2022. The sales increase was driven by a 17% increase in price and a 2% favorable impact from portfolio and other, partially offset by a 7% decline in volume and a 5% unfavorable currency impact. Price gains were driven by strong execution globally, led by EMEA, as farmers prioritize yield to help offset inflation. Pricing actions more than offset currency impacts in EMEA. Volume declines were driven by a shortened Safrinha season due to delayed soybean harvest, supply constraints in Latin America corn, and the 2022 decision to exit Russia. Unfavorable currency impacts were led by the Turkish Lira and the Ukrainian Hryvnia. Segment Operating EBITDA was $652 million in the first quarter of 2023, up 15% from the first quarter of 2022. Price execution and ongoing cost and productivity actions more than offset higher input and freight costs, lower volumes, and increased investment in R&D. Segment operating EBITDA margin improved by approximately 165 basis points versus the prior-year period. 1Q 1Q % % ($ in millions, except where noted) 2023 2022 Change Organic1 Change North America $1,323 $1,184 12% 12% EMEA $1,012 $926 9% 19% Latin America $259 $323 (20)% (24)% Asia Pacific $101 $91 11% 25% Total Seed Net Sales $2,695 $2,524 7% 10% Seed Operating EBITDA $652 $569 15% N/A Crop Protection Summary Crop Protection net sales were approximately $2.2 billion in the first quarter of 2023 compared to approximately $2.1 billion in the first quarter of 2022. The sales increase was driven by an 11% increase in price, partially offset by a 5% unfavorable currency impact and a 1% decline in volume, including the impact of product exits. The increase in price was broad-based and mostly reflected pricing for the value of our differentiated technology, higher raw material and logistical costs, and currency in EMEA. Continued penetration of new products, including EnlistTM and ArylexTM herbicides, was more than offset by delays in the Latin America and Asia Pacific seasons due to unfavorable weather conditions and product exits. Unfavorable currency impacts were led by the Turkish Lira and the Euro. Segment Operating EBITDA was $603 million in the first quarter of 2023, up 23% from the first quarter of 2022. Price execution, productivity actions, and favorable mix more than offset higher input costs, including raw material costs, and the unfavorable impact of currency. Segment operating EBITDA margin improved by more than 390 basis points versus the prior-year period. 1Q 1Q % % ($ in millions, except where noted) 2023 2022 Change Organic1 Change North America $879 $821 7% 8% EMEA $801 $656 22% 35% Latin America $293 $327 (10)% (17)% Asia Pacific $216 $273 (21)% (14)% Total Crop Protection Net Sales $2,189 $2,077 5% 10% Crop Protection Operating EBITDA $603 $491 23% N/A

News Release 1Q 2023 4 2023 Guidance The outlook for agriculture remains robust in 2023, with record demand for grain and oilseeds as ending stocks continue to be under pressure. Commodity prices are above historical averages, and farm balance sheets and income levels remain healthy, leading growers to prioritize technology to maximize return. The Company expects an increase in U.S. planted area and continues to monitor dynamic weather conditions around the world. The Company updated its previously provided guidance3 for the full-year 2023 – increasing sales and earnings expectations for this period, including the impact of its Biologicals acquisitions. Corteva expects net sales in the range of $18.6 billion to $18.9 billion, growth of 7% at the mid-point. Operating EBITDA1 is expected to be in the range of $3.55 billion to $3.75 billion, growth of 13% at the mid-point. Operating EPS1 is expected to be in the range of $2.80 to $3.00 per share, growth of 9% at the mid-point, which reflects higher earnings and lower average share count, partially offset by forecasted higher effective tax rate and interest expense. 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 1Q 2023 5 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-8 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 non-cash 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® and 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. The Company also committed to activities relating to the 2022 Restructuring Actions, which are expected to be completed in 2023. The total net pre-tax restructuring and other charges expected to be recognized during 2023 are not expected to be material. Organic sales is defined as price and volume and excludes currency and portfolio and other impacts, including significant items. 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) credits (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. 5/03/2023 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
