DuPont de Nemours, Inc.

NOTE 19 -SEGMENT INFORMATION

The Company's segments are aligned with the market verticals they serve while maintaining integration and innovation strengths within strategic value chains. DuPont is comprised oftwo operating segments: Healthcare & Water Technologies and Diversified Industrials. Major products by segment include: Healthcare & Water Technologies (specialty components for medical devices, TYVEK® medical packaging and garments, TYCHEM® protective suits, AMBERLITE™ ion exchange resins, FILMTEC™ reverse osmosis and nanofiltration elements and INGE™ and ITEGRATEC™ ultrafiltration modules) and Diversified Industrials (TYVEK® house wrap, STYROFOAM™ insulation, CORIAN® solid surface, Vespel® shapes and parts, MOLYKOTE® specialty lubricants, BETAFORCE™ and BETASEAL™ structural adhesives and Cyrel® flexographic printing plates). The Company operates globally in substantially all of its product lines. Transfers of products between operating segments are generally valued at cost, to the extent such transfers are applicable.

The revenues and certain expenses of the Aramids Business and Electronics Business are classified as discontinued operations in the current and historical periods.

The costs of the Aramids Business and Electronics Business that are classified as discontinued operations include only direct operating expenses incurred by the businesses. Indirect costs, such as those related to corporate and shared service functions previously allocated to the Aramids Business and Electronics Business, do not meet the criteria for discontinued operations and are reported within continuing operations. A portion of these indirect costs include costs related to activities the Company has undertaken or will undertake following the closing of each of the Aramids Divestiture and Electronics Separation, and for which it has been or will be reimbursed (“Future Reimbursable Indirect Costs”). Future Reimbursable Indirect Costs are reported within continuing operations in Corporate but are excluded from Operating EBITDA (as defined below). The remaining portion of these indirect costs are not subject to future reimbursement (“Stranded Costs”). Stranded Costs are reported within continuing operations in Corporate and are included within Operating EBITDA.

The Company's measure of profit/loss for segment reporting purposes is Operating EBITDA as this is the manner in which the Company's chief operating decision maker ("CODM"), the Chief Executive Officer, assesses performance and allocates resources. The CODM utilizes Operating EBITDA to assess financial performance and allocate resources by comparing actual results to historical and previously forecasted results. The Company defines Operating EBITDA as earnings (i.e., “Income from continuing operations before income taxes") before interest, depreciation, amortization, non-operating pension / OPEB benefits / charges, and foreign exchange gains / losses, excluding Future Reimbursable Indirect Costs, environmental remediation costs, including certain investigate, remediate and restoration costs, associated with discontinued or divested operations, businesses or product lines (“Corporate DDOB Remediation Costs”), and is adjusted for significant items. Reconciliations of these measures are provided on the following pages.
