News Release 4Q 2025 2 “ “Our delivery of strong second-half and full-year results reflects continued demand for our differentiated technologies and disciplined execution across the company. In Seed, performance was driven by our latest technology, growth in licensing and sustained productivity improvements. In Crop Protection, despite an ongoing challenging pricing environment in key regions including Latin America and Asia Pacific, we delivered sales and earnings growth, driven by volume gains in new products and biologicals and meaningful cost reductions. We also progressed actions related to our planned separation, and we are on track to complete the separation in the second half of 2026. We look ahead to 2026 with optimism – our products, our employees’ focus on execution, and our accelerated freedom to operate across many crops promises to deliver yet another year of growth, productivity and value creation for both farmers and shareholders.” Chuck Magro Chief Executive Officer Company Updates Separation Update: Key Milestone Targets • Corteva remains on track to complete the planned separation in the second half of 2026 • Key separation milestones expected to be achieved in the first half of 2026: o New Corteva CEO, as well as key executive leadership for both companies, to be named o SpinCo official name and brand identity to be launched o Initial and first amendment to Form 10 to be filed with SEC o Credit agency review and response to capital structure submissions for both companies Bayer Resolution Accelerates Freedom to Operate • Finalized a comprehensive resolution of all litigation with Bayer, providing multi-year clarity on technology access and licensing rights, regulatory certainty / support on Bayer traits, and certainty across all litigation • Agreement helps accelerate Corteva’s path to royalty neutrality to 2026, two years earlier than previously expected, and supports the transition to a net out-licensor of seed technology thereafter • Significantly expands Corteva’s freedom to operate and out-licensing flexibility across corn, canola, and cotton, supporting faster innovation and improved farmer choice • Helps support Corteva’s strategic objective of achieving $1 billion net royalty income position by 2035 • Agreement accelerates multiple technology and market opportunities, contributing ~$1 billion of aggregate earnings upside over the next decade across licensing and branded sales: o Triple-stack corn traits now expected to be available for out-licensing as early as 2027, an acceleration of ~5 years o Third generation above-ground insect traits in corn advanced by ~2 years to the end of the decade o Enables entry into the U.S. cotton out-licensing market, expanding Corteva’s addressable market • $610 million cash outflow, largely in first quarter 2026, funded from strong 2025 free cash flow

News Release 4Q 2025 3 Summary of Fourth Quarter 2025 For the fourth quarter ended December 31, 2025, net sales decreased 2% versus the same period last year. Organic1 sales decreased 4%. Volume was down 5% versus prior year largely due to seasonal timing shifts into third quarter 2025 and first quarter 2026 in both Crop Protection and Seed. Crop Protection volume decreased 2% over the prior year, driven primarily by a seasonal shift in North America to the first quarter of 2026 and the timing of fungicide demand in Latin America. Seed volume decreased 8% versus prior year due primarily to a shift of certain North American deliveries into first quarter 2026 due to freight optimization and weather-related delays, as well as a shift into third quarter 2025 for early deliveries in Latin America in advance of the safrinha season. Price was up 1% versus prior year. Seed price/mix was up 3% over the prior year with gains in nearly all regions, offset by a shift in out- licensing income to the third quarter in North America. Crop Protection price was down 1% driven largely by competitive pricing dynamics in Latin America and partially offset by price/mix increases in North America. GAAP loss from continuing operations after income taxes was $537 million in fourth quarter of 2025 compared to a loss of $50 million in fourth quarter of 2024. Operating EBITDA1 for the fourth quarter of 2025 was income of $446 million, down 15% compared to prior year. 4Q 4Q % % ($ in millions, except where noted) 2025 2024 Change Organic1 Change Net Sales $3,910 $3,978 (2)% (4)% North America $1,478 $1,563 (5)% (5)% EMEA $424 $448 (5)% (9)% Latin America $1,653 $1,622 2% (3)% Asia Pacific $355 $345 3% 7% FY FY % % ($ in millions, except where noted) 2025 2024 Change Organic1 Change Net Sales $17,401 $16,908 3% 4% North America $9,024 $8,660 4% 5% EMEA $3,110 $3,124 - % 2% Latin America $3,928 $3,776 4% 4% Asia Pacific $1,339 $1,348 (1)% 2%

News Release 4Q 2025 4 Seed Summary Seed net sales were $1.74 billion in the fourth quarter of 2025, down from $1.77 billion in the fourth quarter of 2024. The sales decrease reflects an 8% decrease in volume, partially offset by a 3% increase in price/mix and a 3% favorable currency impact. Volume declines in the quarter were due primarily to a shift of certain North American deliveries into first quarter 2026 due to freight optimization and weather-related delays. In addition, early deliveries ahead of the safrinha season in Latin America shifted volumes into the third quarter. The increase in price is due primarily to continued demand for top technology, partially offset by a shift of out-licensing income into the third quarter in North America. Favorable currency impacts were led by the Brazilian Real. Segment operating EBITDA was $124 million in the fourth quarter of 2025, an improvement of 33% from the fourth quarter of 2024. Cost benefits from productivity and deflation drove the improvement versus prior year, partially offset by higher compensation expense, bad debt, and R&D expense. Segment operating EBITDA margin improved by approximately 190 basis points versus the prior-year period. 4Q 4Q % % ($ in millions, except where noted) 2025 2024 Change Organic1 Change North America $545 $639 (15)% (15)% EMEA $190 $216 (12)% (16)% Latin America $884 $827 7% 1% Asia Pacific $118 $90 31% 39% Total 4Q Seed Net Sales $1,737 $1,772 (2)% (5)% 4Q Seed Operating EBITDA $124 $93 33% N/A Seed net sales were $9.90 billion for the full year of 2025, up 4% from the same period of 2024. The sales increase reflects a 3% increase in price/mix and a 2% increase in volume, partially offset by a 1% unfavorable currency impact. Price/Mix gains in all regions, led by North America, demonstrate demand for top technology and the strength of the portfolio, coupled with increased out-licensing income. Volume growth was driven primarily by increased corn area and share gains in North America and Brazil, partially offset by lower soybean area in North America. Unfavorable currency impacts were led by the Turkish lira and Canadian dollar. Segment operating EBITDA was $2.64 billion for the full year of 2025, up 19% from the same period of 2024. Commercial execution and market share gains in North America and Brazil, product mix, reduction of net royalty expense, and ongoing cost and productivity actions more than offset increased compensation, R&D expense, bad debt, selling expenses, and the unfavorable impact of currency. Segment operating EBITDA margin improved by approximately 340 basis points versus the prior-year period.

News Release 4Q 2025 5 Crop Protection Summary Crop Protection net sales were approximately $2.17 billion in the fourth quarter of 2025 compared to approximately $2.21 billion in the fourth quarter of 2024. The sales decrease over the prior period reflects a 2% decrease in volume and a 1% price decline, partially offset by a 2% favorable benefit from currency. The decrease in volume was primarily driven by a seasonal shift to the first quarter of 2026 in North America and the timing of fungicide demand in Latin America, partially offset by strong demand for biologicals. The price decline was primarily due to the competitive pricing environment in Latin America, partially offset by North America price increases. Favorable currency impacts were led by the Brazilian Real. Segment operating EBITDA was $360 million in the fourth quarter of 2025, down 22% from the fourth quarter of 2024. Productivity savings were more than offset by price pressure and higher compensation and R&D costs. Segment operating EBITDA margin declined by approximately 435 basis points versus the prior-year period. 4Q 4Q % % ($ in millions, except where noted) 2025 2024 Change Organic1 Change North America $933 $924 1% 1% EMEA $234 $232 1% (2)% Latin America $769 $795 (3)% (8)% Asia Pacific $237 $255 (7)% (5)% Total 4Q Crop Protection Net Sales $2,173 $2,206 (1)% (3)% 4Q Crop Protection Operating EBITDA $360 $461 (22)% N/A Crop Protection net sales were approximately $7.50 billion for the full year of 2025 compared to approximately $7.36 billion in the same period of 2024. The sales increase reflects a 5% increase in volume, partially offset by a 2% decline in price and a 1% unfavorable impact from currency. The increase in volume was driven by demand for new products, herbicides, and biologicals. The price decline was primarily due to competitive market dynamics in Latin America, partially offset by North America price increases. Unfavorable currency impacts were led by the Turkish Lira and the Brazilian Real. Segment operating EBITDA was $1,350 million for the full year of 2025, up 6% from the same period last year. Raw material deflation, productivity savings, and volume growth more than offset the unfavorable impact of currency, price pressure, and higher compensation and bad debt in SG&A. Segment operating EBITDA margin improved by approximately 70 basis points versus the prior-year period.

News Release 4Q 2025 6 2026 Guidance The global outlook for agriculture remains mixed with strong crop demand and production, but pressured commodity prices and farmer margins. Global corn area was up in 2025, most notably in North America, driven by favorable corn economics relative to soybeans, with a mid-single digit planted area increase in Latin America. However, the large crop production year in 2025 kept pace with record demand. As a result, any shift from corn to soybean planted acres in the US in 2026 is expected to be manageable. The global crop protection industry is expected to improve modestly with volume gains more than offsetting ongoing pricing pressure in certain key regions including Latin America and Asia Pacific. As it pertains to incremental global tariff impacts in 2026 across both businesses, the Company’s current estimate is ~$80 million, which is included in our current 2026 guidance. For the full year 2026, Corteva expects operating EBITDA1 to be $4.0 billion to $4.2 billion, growth of 7% at the mid-point. Operating EPS1 is expected to be $3.45 to $3.70 per share, growth of 7% 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.

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 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. Due to the ramp-up of Enlist E3TM, Corteva significantly reduced 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. In 2023 and 2024, 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 2026. The company expects to record approximately $80 million to $90 million net pre-tax restructuring charges during 2026 for these activities. 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 and separation costs. 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 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 separation costs, the after-tax impact of non-operating benefits (costs), the after-tax impact of amortization expense associated with intangible assets existing as of the Corteva 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 income tax rate less the effect of exchange gains (losses), significant items, separation costs, amortization of intangibles (existing as of Corteva Separation), mark-to-market (gains) losses on certain foreign currency contracts not designated as hedges, and non- operating (benefits) costs. The Company also uses Free Cash Flow as a non-GAAP measure to evaluate and discuss its liquidity position and ability to generate cash. Free Cash Flow is defined as cash provided by (used for) operating activities – continuing operations, less capital expenditures. ® TM Corteva Agriscience and its affiliated companies. 2/3/2026 Media Contact Bethany Shively +1 804-866-2377 bethany.shively@corteva.com Investor Contact Kim Booth +1 302-485-3704 kimberly.a.booth@corteva.com
