PENSION PLANS AND OTHER POST-EMPLOYMENT BENEFITS PENSION PLANS AND OTHER POST-EMPLOYMENT BENEFITS
The significant defined benefit pension and OPEB plans of the Company are summarized below. Unless otherwise noted, all values within this footnote are inclusive of balances and activity associated with the Electronics Business through the spinoff and all Aramids activity related to discontinued operations. The Company transferred standalone and split plans associated with the Electronics Business on the separation date.

Defined Benefit Pension Plans
DuPont has both funded and unfunded defined benefit pension plans covering employees in a number of non-US countries. The United Kingdom qualified plan is the largest pension plan held by DuPont.

DuPont's funding policy is consistent with the funding requirements of each country's laws and regulations. Pension coverage for employees of DuPont'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. During 2025, the Company contributed $55 million to its benefit plans. DuPont expects to contribute approximately $55 million to its benefit plans in 2026.

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

Other Post-employment Benefit Plans
The Company retained U.S. and foreign other post-employment benefit obligations with the U.S. long-term disabilities plan being the largest and accounting for most of the Company's total other post-employment benefit obligations. In comparison to the Company's defined benefit pension plans, the Company's other post-employment benefit plans are not significant. The total other post-employment benefits projected benefit obligation was $17 million as of December 31, 2025 and $27 million as of December 31, 2024. The decrease in the Company's OPEB projected benefit obligation is due to the portion that was spun off with the Electronics Business separation.

Assumptions
The Company determines the expected long-term rate of return on plan assets by performing a detailed analysis of key economic and market factors driving historical returns for each asset class and formulating a projected return based on factors in the current environment. Factors considered include, but are not limited to, inflation, real economic growth, interest rate yield, interest rate spreads, and other valuation measures and market metrics.

Service cost and interest cost for all other plans are determined on the basis of the discount rates derived in determining those plan obligations. The discount rates utilized to measure the majority of pension and other postretirement obligations are based on the Aon AA corporate bond yield curves applicable to each country at the measurement date. DuPont utilizes the mortality tables and generational mortality improvement scales, where available, developed in each of the respective countries in which the Company holds plans.

Plan Assets
Plan assets consist primarily of equity and fixed income securities of U.S. and foreign issuers, and alternative investments such as insurance contracts, pooled investment vehicles and private market securities. At December 31, 2025, plan assets totaled $1.9 billion.

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. 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. The assets are managed by professional investment firms unrelated to the Company. Pension trust funds are permitted to enter into certain contractual arrangements generally described as derivative instruments. Derivatives are primarily used to reduce specific market risks, hedge currency and adjust portfolio duration and asset allocation in a cost-effective manner.

Equity securities primarily included investments in large- and small-cap companies located in both developed and emerging markets around the world. Global equity securities include varying market capitalization levels. U.S. equity investments are primarily large-cap companies. Fixed income securities included investment and non-investment grade corporate bonds of companies diversified across industries, U.S. treasuries, non-U.S. developed market securities, U.S. agency mortgage-backed securities, emerging market securities and fixed income related funds. Global fixed income investments include corporate-issued, government-issued and asset-backed securities. 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. Alternative investments primarily included investments in real estate, various insurance contracts and interest rate, equity, commodity and foreign exchange derivative investments and hedges. Other investments include cash and cash equivalents, pooled investment vehicles, hedge funds 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 other pension plan assets for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models.

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. Valuations of the investments are provided by investment managers or fund managers. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Valuations of insurance contracts are contractually determined and are based on exit price valuations or contract value. Adjustments to valuations are made where appropriate.

Certain pension plan assets are held in funds where fair value is based on an estimated net asset value per share (or its equivalent) as of the most recently available fund financial statements which are received 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 to arrive at an estimated net asset value per share at the measurement date. Where available, audited annual financial statements are obtained and reviewed for the investments as support for the manager’s investment valuation. These funds are not classified within the fair value hierarchy.

Defined Contribution Plans
The Company provides defined contribution benefits to its employees. The most significant is the U.S. Retirement Savings Plan ("the Plan"), which covers all 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 the Company may participate. Currently, the Company contributes 100 percent of the first 6 percent of the employee's contribution election and also contributes 3 percent of each eligible employee's eligible compensation regardless of the employee's contribution. The Company's matching contributions vest immediately upon contribution. The 3 percent nonmatching employer contribution vests after employees complete three years of service. The Company's matching contributions to the Plan were $59 million in 2025 and $60 million in 2024. The Company's nonmatching contributions to the Plan were $32 million for both years ended in 2025 and 2024. In total, the Company's contributions to the Plan were $91 million in 2025 and $92 million in 2024. 2025 amounts are inclusive of Electronics Business through the spin-off and all Aramids activity related to discontinued operations. All amounts in 2024 are inclusive of Electronics Business and Aramids activity related to discontinued operations.
In addition, the Company made contributions to other defined contribution plans for both years ended in 2025 and 2024 in the amount of $32 million. 2025 amounts are inclusive of Electronics Business through the spin-off and Aramids activity related to discontinued operations. All amounts in 2024 are inclusive of Electronics Business and Aramids activity related to discontinued operations.
