NOTE 1 -SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

In these notes, the terms "DuPont" or "Company" used herein mean DuPont de Nemours, Inc. and its consolidated subsidiaries. The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the interim statements reflect all adjustments (including normal recurring accruals) which are considered necessary for the fair statement of the results for the periods presented. Results from interim periods should not be considered indicative of results for the full year. These interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto contained in the Company's Current Report on Form 8-K filed on May 2, 2025, collectively referred to as the "Recast 2024 Annual Report," which was filed in order to recast the Company's 2024 Annual Report on Form 10-K to reflect the changes in the Company's reportable segments. The interim Consolidated Financial Statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained.

Effective in the first quarter of 2025, in light of the Intended Electronics Separation, the Company realigned its management and reporting structure. This realignment resulted in a change in reportable segments in the first quarter of 2025 which changed the manner in which the Company reports financial results by segment, (the "2025 Segment Realignment"). As a result, commencing with the first quarter of 2025, the businesses to be separated as part of the Intended Electronics Separation are reported separately from the other businesses of DuPont. The Consolidated Financial Statements have been recast for all periods presented to reflect the newtwo segment reporting structure as described below:

•ElectronicsCo includes the businesses within the Semiconductor Technologies and Interconnect Solutions lines of business, as well as the electronics-related product lines previously within Industrial Solutions, including electronics polymers and perfluoroeasltomer materials and parts (Kalrez®).

•IndustrialsCo includes the businesses within the former Water & Protection segment, the healthcare and non-electronics businesses, including Vespel® parts and shapes, previously in Industrial Solutions and the Auto Adhesives & Fluids, Multibase TM and Tedlar® businesses, previously within Corporate & Other.
