Overview

On May 26, 2026, DuPont’s Board of Directors announced a reverse stock split of the Company’s common stock, par value $0.01 per share, at a ratio of 1-for-3, as well as a reduction in the number of authorized shares of its common stock by a corresponding ratio (the "Reverse Stock Split"), as approved by shareholders. The Reverse Stock Split became effective on June 24, 2026. All share and share-related information presented in these interim Consolidated Financial Statements has been retroactively adjusted in all periods presented to reflect the decreased number of shares resulting from the Reverse Stock Split and related impacts.

On April 1, 2026, DuPont completed the sale of the Aramids business (the "Aramids Business" and the divestiture of the Aramids Business, the "Aramids Divestiture") to Arclin, a portfolio company of an affiliate of TJC LP for pre-tax cash proceeds of approximately $1.2 billion, subject to customary transaction adjustments, a note receivable in the principal amount of $300 million (the "Aramids Note Receivable") and a non-controlling common equity interest (the "Aramids Equity Consideration"), valued at $325 million, in New Arclin U.S. Holding Corp., which now owns the Arclin global materials business and the Aramids Business. The financial results of the divested Aramids Business are reflected in DuPont's interim Consolidated Financial Statements as discontinued operations, along with comparative periods.

On November 1, 2025, DuPont completed the separation of its semiconductor and interconnect solutions businesses (the "Electronics Business" and the separation of the Electronics Business, the "Electronics Separation") into an independent public company, Qnity Electronics, Inc. ("Qnity"), by way of the distribution to DuPont's stockholders of record as of October 22, 2025 of all the issued and outstanding common stock of Qnity on November 1, 2025 (the "Qnity Distribution"). As a result, the financial results of the divested Electronics Business are reflected in DuPont's interim Consolidated Financial Statements as discontinued operations for all periods.

FORWARD-LOOKING STATEMENTS

Certain statements in this document may be considered forward-looking statements, within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking statements often contain words such as “expect”, “anticipate”, “intend”, “plan”, “believe”, “seek”, “see”, “will”, “would”, “target”, “outlook”, “stabilization”, “confident”, “preliminary”, “initial”, “continue”, “may”, “could”, “project”, “estimate”, “forecast” and similar expressions and variations or negatives of these words. All statements, other than statements of historical fact, are forward-looking statements. Forward-looking statements address matters that are, to varying degrees, uncertain and subject to risks, uncertainties, and assumptions, many of which are beyond DuPont's control, that could cause actual results to differ materially from those expressed in any forward-looking statements.

Forward-looking statements are not guarantees of future results. Some of the important factors that could cause DuPont's actual results to differ materially from those projected in any such forward-looking statements include, but are not limited to (i) the ability to realize the intended benefits of the Electronics Separation and the Qnity Distribution, including achievement of the intended tax treatment, contractual allocation to, and assumption by Qnity of certain liabilities, including certain legacy liabilities with respect to per- and polyfluoroalkyl substances ("PFAS") and the possibility of disputes, litigation or unanticipated costs in connection with the Electronics Separation and Qnity Distribution; (ii) the impact of the Aramids Divestiture on DuPont’s balance sheet, financial condition and future results of operations; (iii) risks and costs related to the impact of the arrangement to share future eligible PFAS costs by and among DuPont, Corteva, Inc. and The Chemours Company, including the outcome of pending or future litigation related to PFAS or PFOA, which includes personal injury claims and natural resource damages claims; the extent and cost of ongoing and potential future remediation obligations; and changes in laws and regulations applicable to PFAS chemicals; (iv) the failure to realize expected benefits and effectively manage and achieve anticipated synergies and operational efficiencies in connection with the Electronics Separation, the Aramids Divestiture and completed and future, if any, divestitures, mergers, acquisitions, and other portfolio management, productivity and infrastructure actions; (v) risks and uncertainties that are outside the Company’s control but adversely impact the overall environment in which DuPont, its customers and/or its suppliers operate, including changes in economic, political, regulatory, international trade, geopolitical, military conflicts, capital markets and other external conditions, including pandemics and responsive actions, as well as natural and other disasters or weather-related events; (vi) the ability to offset increases in cost of inputs, including raw materials, energy and logistics; (vii) the risks and uncertainties associated with continuing or expanding geopolitical conflicts or trade disputes or restrictions and responsive actions, new or increased tariffs

or export controls, including on exports to China of U.S.-regulated products and technology; (viii) other risks to DuPont’s business and operations, including the risk of impairment; (ix) risks and uncertainties in connection with completing the $2 billion share buyback announced on November 6, 2025, including timeline, associated costs and the possibility that the authorization may be suspended or discontinued prior to completion; (x) the ability to realize the intended benefits of the Reverse Stock Split; (xi) the impact of the invalidation of certain tariffs imposed under the International Emergency Economic Powers Act and (xii) other risk factors discussed in DuPont’s most recent annual report on Form 10-K, and subsequent quarterly reports on Form 10-Q and current reports on Form 8-K filed with the U.S. Securities and Exchange Commission.

Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business or supply chain disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on DuPont’s consolidated financial condition, results of operations, credit rating or liquidity. Undue reliance should not be placed on forward-looking statements, which speak only as of the date they are made. DuPont assumes no obligation to publicly provide revisions or updates to any forward-looking statements whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws.
