News Release 3Q 2021 3 Summary of Year-to-Date 2021 For the nine months ending September 30, 2021, net sales increased 11% versus the same period last year. Organic1 sales rose 9%. Sales increased in all regions on a reported and organic1 basis, with double-digit organic1 gains in Latin America. Volume grew 6% versus the prior-year period, with gains in both segments led by ongoing penetration of new technology. Sales of new and differentiated Crop Protection products drove double-digit net sales gains for the segment, with an organic1 sales increase of 13%. Seed net sales rose 8% for the year-to-date period, primarily driven by increased North America2 planted area and share gains in the Brazil Safrinha season. Price increased 3% versus prior year, with gains in both segments and all regions. Higher prices reflect ongoing execution on a price-for-value strategy globally and pricing for higher raw material and logistical costs. GAAP income from continuing operations after income taxes was $1.7 billion year-to-date in 2021. Operating EBITDA1 for the period was $2.31 billion, up 25% compared to prior year. 3Q 3Q % % ($ in millions, except where noted) 2021 2020 Change Organic1 Change Net Sales $2,371 $1,863 27% 24% North America $590 $487 21% 20% EMEA $390 $315 24% 19% Latin America $1,097 $805 36% 31% Asia Pacific $294 $256 15% 16% YTD YTD % % ($ in millions, except where noted) 2021 2020 Change Organic1 Change Net Sales $12,176 $11,010 11% 9% North America $6,175 $5,818 6% 5% EMEA $2,702 $2,425 11% 7% Latin America $2,203 $1,754 26% 27% Asia Pacific $1,096 $1,013 8% 7%

News Release 3Q 2021 4 Crop Protection Summary Crop Protection net sales were approximately $1.6 billion in the third quarter of 2021 compared to approximately $1.3 billion in the third quarter of 2020. The sales increase was driven by a 16% increase in volume, a 3% increase in price and a 3% favorable impact from currency. Volume growth was driven by continued penetration of new products, including IsoclastTM insecticide and ArylexTM herbicide, coupled with strong customer demand and an accelerated start to the season in Latin America, which shifted an estimated $100 million in sales from the fourth quarter. Gains were partially offset by an approximate $70 million impact from the decision to phase out select low- margin products. The increase in price was driven by gains in Latin America. Favorable currency impacts were primarily from the Brazilian Real. Segment Operating EBITDA was $206 million in the third quarter of 2021, up 58% from the third quarter of 2020. Volume gains from new products, favorable mix, productivity actions, and continued pricing execution more than offset higher costs, including raw materials and SG&A. 3Q 3Q % % ($ in millions, except where noted) 2021 2020 Change Organic1 Change North America $422 $390 8% 8% EMEA $237 $198 20% 17% Latin America $763 $559 36% 31% Asia Pacific $211 $193 9% 10% Total 3Q Crop Protection Net Sales $1,633 $1,340 22% 19% Crop Protection net sales were approximately $5.2 billion for the first nine months of 2021 compared to approximately $4.5 billion in the first nine months of 2020. The increase was due to a 9% increase in volume, a 4% increase in price and a 3% favorable impact from currency, partially offset by a 1% unfavorable portfolio impact. Volume growth was led by continued penetration of new products, including ArylexTM herbicide and IsoclastTM insecticide. These volume gains were partially offset by an approximate $200 million impact from our decision to phase out select low-margin products. The increase in price was largely driven by gains in Latin America and North America, including pricing for higher raw material and logistical costs. Favorable currency impacts were primarily from the Euro. The portfolio impact was driven by prior-year divestitures in Asia Pacific. Segment Operating EBITDA was $897 million for the first nine months of 2021, up 32% from the first nine months of 2020. Continued penetration of new products, favorable mix, ongoing cost and productivity actions, and a favorable impact from currency more than offset higher input costs, including raw material and logistics costs. Segment Operating EBITDA margin improved by more than 230 basis points versus the prior-year period.

News Release 3Q 2021 5 Seed Summary Seed net sales were $738 million in the third quarter of 2021, up from $523 million in the third quarter of 2020. The increase was due to a 19% increase in price, an 18% increase in volume and a 4% favorable impact from currency. The increase in price was led by strong execution in Latin America coupled with fewer corn replant units in North America. Higher volumes were driven by lower corn and cotton returns in North America, coupled with higher other seed sales in India. These volume gains were partially offset by robust early demand for corn in Latin America and an early settlement of the canola season in Canada, which shifted approximately $80 million of sales into the second quarter. Favorable currency impacts were primarily driven by the South African Rand and the Brazilian Real. Segment Operating EBITDA was $(217) million in the third quarter of 2021, an improvement of 23% compared to prior year. Continued price execution, higher volumes, lower royalties, and ongoing cost and productivity actions more than offset higher costs including commodity costs and SG&A. 3Q 3Q % % ($ in millions, except where noted) 2021 2020 Change Organic1 Change North America $168 $97 73% 71% EMEA $153 $117 31% 22% Latin America $334 $246 36% 32% Asia Pacific $83 $63 32% 32% Total 3Q Seed Net Sales $738 $523 41% 37% Seed net sales were approximately $7.0 billion for the first nine months of 2021, up from approximately $6.5 billion in the year-ago period. The increase was due to a 4% increase in volume, a 3% increase in price and a 1% favorable impact from currency. The increase in volume was driven by higher soybean and corn sales in North America, market share gains in Brazil Safrinha, and canola growth in Canada. Price gains were driven by strong adoption of new Seed technology, including price execution in Latin America and EMEA, with corn price up 4% globally. These gains were partially offset by competitive pricing pressure in North America soybeans, where price was down 3%. Favorable currency impacts primarily from the Canadian Dollar and the Euro more than offset unfavorable impacts from the Brazilian Real. Segment Operating EBITDA was $1.5 billion for the first nine months of 2021, up 21% from the prior year. Continued price execution, volume gains, lower royalties, ongoing cost and productivity actions, and lower bad debt expense more than offset higher input costs and higher freight and warehousing costs. Segment Operating EBITDA margin improved by more than 240 basis points versus the prior-year period.

News Release 3Q 2021 6 Updated 2021 Outlook The Company increased its previously provided net sales guidance3 for the full year 2021 and now expects net sales in the range of $15.5 billion to $15.7 billion, which at the mid-point represents expected net sales growth of approximately 10% for the year. Operating EBITDA1 guidance was affirmed in the range of $2.5 billion to $2.6 billion – representing growth of 22% for the year at the midpoint. Operating EPS1 guidance was increased to $2.05 to $2.15 per share, which represents 40% growth at the midpoint. 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 2021 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 per share, and base 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 additional, useful information to investors as they provide insight with respect to ongoing operating results of the Company and a 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 their 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, on February 1, 2021, Corteva approved restructuring actions designed to right-size and optimize footprint and organizational structure according to the business needs in each region with the focus on driving continued cost improvement and productivity. The restructuring actions are expected to be substantially complete in 2021. Organic sales is defined as price and volume and excludes currency and portfolio impacts. Operating EBITDA is defined as earnings (i.e., income from continuing operations before income taxes) before interest, depreciation, amortization, non-operating benefits, net and foreign exchange gains (losses) net, 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 (including goodwill impairment charges). Non-operating benefits, net consists of non-operating pension and other post-employment benefit (OPEB) credits, tax indemnification adjustments, 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 per share are defined as “Earnings per common share from continuing operations - diluted” excluding the after-tax impact of significant items (including goodwill impairment charges), the after tax impact of non-operating benefits, net, and 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 net gain (loss) from the changes in fair value of the non-qualified foreign currency derivative contracts will be reported in 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 tax rate is defined as the effective tax rate excluding the impacts of foreign exchange gains (losses) net, non-operating benefits, net, amortization of intangibles as of the Separation from DowDuPont, and significant items (including goodwill impairment charges). ® TM Corteva Agriscience and its affiliated companies. 11/03/2021 Media Contact Kasey Anderson +1 317-337-4478 kasey.anderson@corteva.com Investor Contact Jeff Rudolph +1 302-485-3704 jeff.rudolph@corteva.com
