Pension and Other Postretirement Benefits Disclosure [Text Block] PENSION PLANS AND OTHER POST-EMPLOYMENT BENEFITS
The company offers various long-term benefits to its employees. Where permitted by applicable law, the company reserves the right to change, modify or discontinue the plans.

Defined Benefit Pension Plans
The company has both funded and unfunded noncontributory defined benefit pension plans covering employees in the U.S. and non-U.S. countries. The principal U.S. pension plan is the largest pension plan held by Corteva. Effective January 1, 2007, most new hires were no longer eligible to participate in the U.S. defined benefit pension plans. On November 30, 2018, the company froze the pay and service amounts used to calculate the pension benefits for active employees who participate in the pension plan. As a result, no participants are currently accruing additional benefits in the pension plan.

The company's funding policy is consistent with the funding requirements of federal laws and regulations. Pension coverage for employees of the company's non-U.S. consolidated subsidiaries is provided, to the extent deemed appropriate, through separate
plans. Obligations under such plans are funded by depositing funds with trustees, covered by insurance contracts, or remain unfunded.

The company made total contributions of $40 million, $50 million and $52 million to its pension plans other than the principal U.S. pension plan for the years ended December 31, 2025, 2024 and 2023, respectively. Corteva expects to contribute approximately $40 million to its pension plans other than the principal U.S. pension plan in 2026. In planning for the Proposed Separation, including the future capital structures of the two new companies, the company expects to evaluate discretionary contributions to its principal U.S. pension plan in 2026.

The weighted-average assumptions used to determine pension plan obligations for all pension plans are summarized in the table below:

1.The rate of compensation increase excludes U.S. pension plans since the employees who participate in the U.S. pension plans no longer accrue additional benefits for future service and eligible compensation.

The weighted-average assumptions used to determine net periodic benefit costs for all pension plans are summarized in the table below:

Other Post-Employment Benefits
The company has historically provided medical, dental and life insurance benefits to certain pensioners and survivors. The majority of U.S. employees hired on or after January 1, 2007, and eligible employees under the age of 50 as of November 30, 2018, are not eligible to participate in the post-employment medical, dental and life insurance plans. Substantially all of the cost and liabilities for these retiree benefit plans are attributable to the U.S. benefit plans. The non-Medicare eligible retiree medical plan is contributory with costs shared between the company and pensioners and survivors. For Medicare eligible pensioners and survivors, Corteva provides a company-funded Health Reimbursement Arrangement ("HRA"). In December 2020, the company amended its retiree medical, dental and life insurance plans to no longer provide retiree dental and life insurance benefits effective January 1, 2022 and to cap Corteva’s portion of the cost of non-Medicare retiree medical coverage to the level in effect as of December 31, 2021 ("2020 OPEB Plan Amendments").

The company also provides disability benefits to employees. In most countries, employee disability benefit plans are insured. In the U.S., these plans are generally self-insured. Obligations and expenses for self-insured plans are reflected in the change in projected benefit obligations table on page F-50.

The company's OPEB plans are unfunded and the cost of the approved claims is paid from operating cash flows. Pre-tax cash requirements to cover actual net claims costs and related administrative expenses were $96 million, $101 million, and $97 million for the years ended December 31, 2025, 2024 and 2023, respectively. Changes in cash requirements reflect the net impact of per capita health care costs, demographic changes, plan amendments and changes in participant premiums, co-payments and deductibles. In 2026, the company expects to contribute approximately $100 million for its OPEB plans.

The weighted-average assumptions used to determine benefit obligations for OPEB plans are summarized in the table below:
Weighted-Average Assumptions used to Determine Benefit ObligationsDecember 31, 2025December 31, 2024
Discount rate5.14 %5.50 %
The weighted-average assumptions used to determine net periodic benefit costs for the OPEB plans are summarized in the table below:
Weighted-Average Assumptions used to Determine Net Periodic Benefit CostFor the Year Ended December 31,

As of December 31, 2025, 2024 and 2023, health care cost trend rates do not impact the benefit obligations for the OPEB plans because of the 2020 OPEB Plan Amendments.

Assumptions
For the U.S. plan, the company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. Where appropriate, asset-liability studies are also taken into consideration. The expected long-term rate of return on plan assets is based upon historical real returns (net of inflation) for the asset classes covered by the investment policy, expected performance, and projections of inflation and interest rates over the long-term period during which benefits are payable to plan participants. For non-U.S. plans, assumptions reflect economic assumptions applicable to each country.

In the U.S., Corteva calculates service costs and interest costs by applying individual spot rates from a yield curve (based on high-quality corporate bond yields) to the separate expected cash flows components of service cost and interest cost. Service cost and interest cost for all other plans are determined based on the single equivalent discount rates derived in determining those plan obligations.

For U.S. benefit plans, the discount rates utilized to measure the pension and other post-employment benefit obligations are based on the yield of high-quality corporate fixed income investments at the measurement date. Future expected actuarially determined cash flows are individually discounted at the spot rates under the Aon AA_Above Median yield curve (based on high-quality corporate bond yields) to arrive at the plan’s obligations as of the measurement date. For non-U.S. benefit plans, historically the company utilized prevailing long-term high quality corporate bond indices to determine the discount rate, applicable to each country, at the measurement date.

The company adopts the most recently published mortality tables and mortality improvement scale released by the Society of Actuaries in measuring its U.S. pension and other post-employment benefit obligations. The effect of these adoptions is amortized into net periodic benefit cost for the years following the adoption.

Plan Assets
All pension plan assets in the U.S. are invested through a single master trust fund. The general principles guiding U.S. pension asset investment policies are those embodied in the Employee Retirement Income Security Act of 1974 ("ERISA"). These principles include discharging Corteva's investment responsibilities for the exclusive benefit of plan participants and in accordance with the "prudent expert" standard and other ERISA rules and regulations. Corteva establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. The strategic asset allocation for this trust fund is approved by the Pension Investment Committee. Strategic asset allocations in other countries are selected in accordance with the laws and practices of those countries. Where appropriate, asset-liability studies are utilized in this process.

U.S. plan assets are managed by investment professionals employed by Corteva, and plan assets for non-U.S. plans are managed by professional investment firms unrelated to the company. Corteva's pension investment professionals have discretion to manage the assets within established asset allocation ranges approved by the Pension Investment Committee. Additionally, pension trust funds are permitted to enter into certain contractual arrangements generally described as "derivatives." Derivatives are primarily used to reduce specific market risks, hedge currency and adjust portfolio duration and asset allocation in a cost-effective manner.

The weighted-average allocation for plan assets of the company's pension plans is summarized as follows:

Total 100 %100 %

U.S. equity investments are primarily large-cap companies. Non-U.S. equity securities include varying market capitalization levels. Fixed income securities include corporate-issued, government-issued and asset-backed securities of both U.S. and non-U.S. issuers. Corporate debt investments include a range of credit risk and industry diversification. U.S. fixed income investments are weighted heavier than non-U.S. fixed income securities. Other investments include cash and cash equivalents, hedge funds, real estate and private market securities such as interests in private equity and venture capital partnerships.

Fair value calculations may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

For pension plan assets classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs.

For pension plan assets classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance and quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates, interest rates and implied volatilities obtained from various market sources.

For pension plan assets classified as Level 3 measurements, total fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. Investment managers, fund managers, or
investment contract issuers provide valuations of the investment on a monthly or quarterly basis. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Adjustments to valuations are made where appropriate. Where available, audited financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation.

The tables below present the fair values of the company's pension assets by level within the fair value hierarchy, as described in Note 2 - Summary of Significant Accounting Policies, in the Consolidated Financial Statements:

Trust Assets
EIDP entered into a trust agreement in 2013 (as amended and restated in 2017, "the Trust") that established and requires EIDP to fund the Trust for cash obligations under certain non-qualified benefit and deferred compensation plans upon a change in control event as defined in the Trust agreement. Under the Trust agreement, the consummation of the Merger was a change in control event and resulted in a contribution to the Trust by EIDP. Additionally, the Corteva Separation resulted in Corteva transferring a portion of the balance of the Trust to DuPont at the Corteva Separation date. During the years ended December 31, 2025 and 2024, $37 million and $48 million, respectively, was distributed by EIDP according to the Trust agreement, and at December 31, 2025 and 2024, the balance in the Trust was $147 million and $176 million, respectively. The Trust Assets are classified as current restricted cash equivalents and included within other current assets in the Consolidated Balance Sheets. See Note 6 - Supplementary Information, to the Consolidated Financial Statements, for further information.

Defined Contribution Plans
Corteva provides defined contribution benefits to its employees. The most significant is the U.S. Retirement Savings Plan ("the Plan"), which covers almost all of the U.S. full-service employees. This Plan includes a non-leveraged Employee Stock Ownership Plan ("ESOP"). Employees are not required to participate in the ESOP and those who do are free to diversify out of the ESOP. The purpose of the Plan is to provide retirement savings benefits for employees and to provide employees an opportunity to become stockholders of the company. The Plan is a tax qualified contributory profit sharing plan, with cash or deferred arrangement and any eligible employee of Corteva may participate. Currently, Corteva contributes 100 percent of the first six percent of the employee's contribution election and also contributes three percent of each eligible employee's eligible compensation regardless of the employee's contribution.
Corteva's contributions to the Plan were $99 million, $100 million and $101 million for the years ended December 31, 2025, 2024 and 2023, respectively. Corteva's matching contributions vest immediately upon contribution. The three percent nonmatching company contribution vests after employees complete three years of service. In addition, Corteva made contributions to other defined contribution plans of $51 million, $46 million and $45 million for the years ended December 31, 2025, 2024 and 2023, respectively.
