Effective April 1, 2025 (fiscal year 2026), DXC Technology ("DXC" or the "Company") began reporting its financial results under a new segment structure designed to better reflect the Company’s operational structure and the delivery of end-to-end IT services. The new structure includes three reportable segments that align with how management runs the business and allocates resources: Consulting & Engineering Services ("CES"), Global Infrastructure Services ("GIS"), and Insurance Services ("Insurance"). Descriptions for each segment are provided below:

We have prepared unaudited historical consolidated financial information based on the new reporting structure, which includes certain non-GAAP measures.

We define segment profit as segment revenues less costs of services, segment selling, general and administrative, depreciation and amortization, and other segment items. The Company allocates certain costs such as real estate costs, information technology costs and costs for certain other shared corporate functions to it segments using a proportional share of either revenue or headcount for each segment.

Segment profit excludes various non-GAAP adjustments, including:

•Restructuring costs – includes costs, net of reversals, related to workforce and real estate optimization and other similar charges.

•Transaction, separation and integration-related (“TSI”) costs – includes third party costs related to integration, separation, planning, financing and advisory fees and other similar charges associated with mergers, acquisitions, strategic investments, joint ventures, and dispositions and other similar transactions incurred within one year of such transactions closing, except for costs associated with related disputes, which may arise more than one year after closing.

•Amortization of acquired intangible assets – includes amortization of intangible assets acquired through business combinations.

•Merger-related indemnification – in fiscal 2025 and fiscal 2024, represents the Company’s estimate of potential net liability to HPE for tax related indemnifications.

•Gains and losses on dispositions – gains and losses related to dispositions of businesses, strategic assets and interests in less than wholly-owned entities.

•Gains and losses on real estate and facility sales – gains and losses related to dispositions of real property.

•Impairment losses – non-cash charges associated with the permanent reduction in the value of the Company’s assets (e.g., impairment of goodwill and other long-term assets including fixed assets and impairments to deferred tax assets for discrete changes in valuation allowances). Future discrete reversals of valuation allowances are likewise excluded.

•Pension and OPEB actuarial and settlement gains and losses – pension and OPEB actuarial mark to market adjustments and settlement gains and losses.

Certain corporate costs and other expenses managed centrally are not allocated to individual segments. As part of the transition to the new segment structure, the Company updated the assumptions that define which expenses remain in corporate post allocation. The tables below reflect those revised assumptions.
