Price was up 14% globally, led by continued execution on the Company’s price for value strategy and recovery of higher input costs. Volume declines were driven by the exit from Russia, lower corn planted area in EMEA2, and lower corn volumes in Latin America, partially offset by increased corn acres in North America2. • Crop Protection net sales decreased 10% and organic1 sales decreased 12%. Volume declines, largely in Latin America and North America2, were driven by strategic product exits, inventory destocking, and delayed farmer purchases. Price gains reflected pricing for value and strong execution in response to cost inflation led by EMEA2 and North America2. • GAAP income and earnings per share (EPS) from continuing operations were $1.17 billion and $1.63 per share for the period, respectively, down from prior year driven by lower volumes, unfavorable currency and non- cash charges associated with legacy retirement plans, partially offset by pricing, productivity, lower restructuring charges and lower effective tax rate. Operating EBITDA1 was $2.99 billion, a 5% improvement over prior year on price execution and productivity actions, partially offset by lower volumes coupled with cost and currency headwinds. Operating EPS1 was $2.54 per share, up 2% compared to prior year. • Management affirmed full year 2023 net sales and earnings guidance3. Net sales is expected to be in the range of $17.0 billion to $17.3 billion and Operating EBITDA1 is expected to be in the range of $3.25 billion to $3.45 billion. Operating EPS1 is expected to be in the range of $2.50 to $2.70 per share. 1. Organic Sales, Operating EPS and Operating EBITDA are non-GAAP measures. See page A-5 for further discussion. 2. North America is defined as U.S. and Canada. EMEA is defined as Europe, Middle East and Africa. 3. The Company does not provide the most comparable GAAP measure on a forward-looking basis.

News Release 3Q 2023 2 Chuck Magro Chief Executive Officer Summary of Third Quarter 2023 For the third quarter ended September 30, 2023, net sales decreased 7% versus the same period last year. Organic1 sales declined 13%. Volume declined 15% versus the prior-year period driven by strategic product exits and ongoing headwinds in the Crop Protection segment. Lower Seed volumes were driven by the timing of seasonal demand in Latin America and an earlier operational finish to the season in North America versus prior year. Price increased 2% versus prior year, reflecting continued execution on the Company’s price for value strategy, while managing increased competitive pressure. GAAP income from continuing operations after income taxes was a loss of $315 million in third quarter 2023 compared to a loss of $322 million in third quarter 2022. Operating EBITDA1 for the third quarter was $18 million, down 81% compared to prior year. The Company announced a plan to further optimize its Crop Protection network of manufacturing facilities and external partners. The plan includes the exit of the Company’s production activities at its site in Pittsburg, California, as well as ceasing operations in select manufacturing lines at other locations. As a result, the Company expects to record total pre-tax restructuring and asset related charges of $410 million to $460 million through 2024, with an estimated $90 million to $120 million of cash payments. The Company expects to achieve approximately $100 million in run-rate savings by 2025 as a result of these actions. 3Q 3Q % % ($ in millions, except where noted) 2023 2022 Change Organic1 Change Net Sales $2,590 $2,777 (7)% (13)% North America $572 $739 (23)% (23)% EMEA $469 $454 3% (1)% Latin America $1,224 $1,281 (4)% (18)% Asia Pacific $325 $303 7% 10% 2023 2022 % % ($ in millions, except where noted) YTD YTD Change Organic1 Change Net Sales $13,519 $13,630 (1)% (1)% North America $7,093 $6,822 4% 4% EMEA $2,996 $2,894 4% 9% Latin America $2,384 $2,764 (14)% (24)% Asia Pacific $1,046 $1,150 (9)% (3)%

News Release 3Q 2023 3 Seed Summary Seed net sales were $878 million in the third quarter of 2023, up from $862 million in the third quarter of 2022. The sales increase was driven by a 14% increase in price, partially offset by a 12% decline in volume. The increase in price was broad-based, driven by strong demand for top technology products, and strong operational execution across the portfolio. Lower volumes were driven by expected lower planted area and delayed farmer purchases in Brazil, and an earlier operational finish to the season in North America versus prior year. Segment operating EBITDA was a loss of $138 million in the third quarter of 2023, an improvement of 38% from the third quarter of 2022. Price execution, reduction of net royalty expense, and ongoing cost and productivity actions more than offset higher input and freight costs, lower volumes, and the unfavorable impact of currency. 3Q 3Q % % ($ in millions, except where noted) 2023 2022 Change Organic1 Change North America $173 $218 (21)% (20)% EMEA $198 $157 26% 32% Latin America $380 $383 (1)% (5)% Asia Pacific $127 $104 22% 28% Total 3Q Seed Net Sales $878 $862 2% 2% 3Q Seed Operating EBITDA $(138) $(224) 38% N/A Seed net sales were $7.8 billion for the first nine months of 2023, up from approximately $7.3 billion in the same period of 2022. The sales increase was driven by a 14% increase in price and 1% favorable impact from portfolio. This gain was partially offset by a 5% decline in volume and a 3% unfavorable currency impact. The increase in price was driven by strong demand for top technology and operational execution globally, with global corn and soybean prices up 15% and 8%, respectively. Pricing actions more than offset currency impacts in EMEA. The decline in volume was driven by the 2022 decision to exit Russia, lower corn planted area in EMEA, and lower-than-expected corn planted area projected in Brazil, partially offset by increased corn acres in North America. Unfavorable currency impacts were led by the Turkish Lira and the Canadian Dollar. Segment operating EBITDA was $1.97 billion for the first nine months of 2023, up 24% from the same period last year. Price execution, reduction of net royalty expense, and ongoing cost and productivity actions more than offset higher input and freight costs, lower volumes, and the unfavorable impact of currency. Segment operating EBITDA margin improved by more than 350 basis points versus the prior-year period. 2023 2022 % % ($ in millions, except where noted) YTD YTD Change Organic1 Change North America $5,192 $4,637 12% 13% EMEA $1,441 $1,442 - % 6% Latin America $847 $912 (7)% (11)% Asia Pacific $357 $342 4% 13% Total YTD Seed Net Sales $7,837 $7,333 7% 9% YTD Seed Operating EBITDA $1,972 $1,585 24% N/A

News Release 3Q 2023 4 Crop Protection Summary Crop Protection net sales were approximately $1.7 billion in the third quarter of 2023 compared to approximately $1.9 billion in the third quarter of 2022. The sales decrease was driven by a 16% decrease in volume and a 4% decrease in price, partially offset by a 7% favorable impact from the Biologicals acquisitions and a 2% favorable impact from currency. The decrease in volume was driven by strategic product exits, inventory destocking trends, timing of seasonal demand, and delayed farmer purchases, impacting volumes across all regions. Pricing gains in EMEA and Asia Pacific were offset by price declines in North America and Latin America, driven by elevated competitive pressure. Favorable currency impacts were led by the Brazilian Real and the Euro. The portfolio impact was driven by the Biologicals acquisitions, which added approximately $145 million of net sales. Segment operating EBITDA was $184 million in the third quarter of 2023, down 48% from the third quarter of 2022. Volume and pricing declines and higher input costs more than offset productivity actions. Segment operating EBITDA margin declined by approximately 760 basis points versus the prior-year period. 3Q 3Q % % ($ in millions, except where noted) 2023 2022 Change Organic1 Change North America $399 $521 (23)% (25)% EMEA $271 $297 (9)% (18)% Latin America $844 $898 (6)% (23)% Asia Pacific $198 $199 (1)% 1% Total 3Q Crop Protection Net Sales $1,712 $1,915 (11)% (20)% 3Q Crop Protection Operating EBITDA $184 $352 (48)% N/A Crop Protection net sales were approximately $5.7 billion for the first nine months of 2023 compared to approximately $6.3 billion in the same period of 2022. The sales decrease was driven by a 16% decrease in volume and a 2% unfavorable impact from currency. These declines were partially offset by a 4% increase in price and a 4% favorable impact from the Biologicals acquisitions. The decrease in volume was driven by strategic product exits, inventory destocking trends, and delayed farmer purchases. The increase in price was broad-based, with gains in most regions led by EMEA and North America, and mostly reflected pricing for the value of our differentiated technology, including new products, and currency in EMEA. Unfavorable currency impacts were led by the Turkish Lira and Chinese Renminbi. The portfolio impact was driven by the Biologicals acquisitions, which added approximately $280 million of net sales. Segment operating EBITDA was $1.1 billion for the first nine months of 2023, down 18% from the same period last year. Pricing execution and productivity actions were more than offset by lower volumes, higher input costs, and the unfavorable impact of currency. Segment operating EBITDA margin decreased approximately 200 basis points versus the prior-year period. 2023 2022 % % ($ in millions, except where noted) YTD YTD Change Organic1 Change North America $1,901 $2,185 (13)% (13)% EMEA $1,555 $1,452 7% 11% Latin America $1,537 $1,852 (17)% (31)% Asia Pacific $689 $808 (15)% (10)% Total YTD Crop Protection Net Sales $5,682 $6,297 (10)% (12)% YTD Crop Protection Operating EBITDA $1,107 $1,352 (18)% N/A

News Release 3Q 2023 5 2023 Guidance The global outlook for agriculture remains positive overall in 2023, with high demand for grain and oilseeds. Commodity prices are above historical averages, and farm balance sheets and income levels remain generally healthy, encouraging growers to prioritize technology to maximize return. The Company’s outlook for its operations in Brazil has been revised, influenced by lower-than-expected corn planted area, ongoing headwinds in crop chemicals, delayed farmer purchases on both plantings and crop protection applications, as well as elevated levels of generic products, leading to an update to full-year 2023 net sales and earnings expectations in October 2023. Corteva expects net sales in the range of $17.0 billion to $17.3 billion, down 2% versus prior year at the mid-point. Operating EBITDA1 is expected to be in the range of $3.25 billion to $3.45 billion, growth of 4% at the mid-point. Operating EPS1 is expected to be in the range of $2.50 to $2.70 per share, down 3% at the mid-point. 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 2023 6 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 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 ramp-up period of Enlist E3TM, Corteva has begun 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 thereafter. During 2023, the company committed to restructuring activities to optimize the Crop Protection network of manufacturing and external partners, which are expected to be substantially complete in 2024. The company expects to record approximately $265 million to $285 million net pre-tax restructuring charges during 2023 for these activities. The company also expects non-operating charges associated with pension and OPEB costs to increase in 2023 when compared to 2022, which is mainly due to an increase in discount rates and a decrease in asset returns due to lower pension plan assets. 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. 11/08/2023 Media Contact Bethany Shively +1 202-997-9438 bethany.shively@corteva.com Investor Contact Kim Booth +1 302-485-3704 kimberly.a.booth@corteva.com
