Nokia provides recast comparative segment results for 2025 and 2024 reflecting new operating and financial reporting structure

Nokia today provides recast comparative segment financial information on a quarterly and annual basis for 2025, and on an annual basis for 2024, reflecting the previously announced changes in its operating and financial reporting structure.

Changes in operating and reporting structure, effective from 1 January 2026

On 19 November 2025, Nokia announced together with its new strategy that it will reorganize its business into two primary operating segments to better align to customer needs and accelerate innovation as the AI supercycle increases demand for advanced connectivity. This reorganization took effect as of 1 January 2026.

The reorganization recognizes Network Infrastructure as a growth segment, positioned to capitalize on the rapid, global AI and data center build-out while continuing to innovate for its telecommunications customer base. The segment consists of three business units Optical Networks, IP Networks and Fixed Networks and is led by David Heard.

The new Mobile Infrastructure segment brings together Nokia’s Core Networks portfolio, Radio Networks portfolio and Technology Standards (formerly Nokia Technologies). It is positioned for core and radio network technology and services leadership to lead the industry to AI-native networks and 6G. The new segment brings together a portfolio whose value creation is founded on mobile communication technologies based on 3GPP standards with a strong cash flow position underpinned by IP licensing. It is led by Justin Hotard on an interim basis and consists of three business units Core Software, Radio Networks and Technology Standards.

In addition, as part of its strategy work, Nokia identified several units which are not seen as core to the future of the company’s strategy. These units were moved into a dedicated operating segment called Portfolio Businesses while the company assesses the best value creating opportunity for them. The units moved were: (i) Fixed Wireless Access CPE (previously in Fixed Networks in Network Infrastructure), (ii) Site Implementation and Outside Plant (previously in Fixed Networks in Network Infrastructure), (iii) Enterprise Campus Edge (previously in Cloud and Network Services), and (iv) Microwave Radio (previously in Mobile Networks).

Recast comparative segment financial information for 2025 and 2024

Nokia will report its segment financial information in accordance with the new organizational structure beginning with its Q1 2026 financial results. In addition to full segment financial information for its three operating segments, Nokia will disclose net sales information for the business units within its Network Infrastructure and Mobile Infrastructure segments. Furthermore, Nokia will continue providing segment-level data for Group Common and Other.

To provide a basis for comparison, the following tables present summarized unaudited income statement information on a recast basis for all four quarters and full year of 2025, as well as for the full year 2024, for Network Infrastructure, Mobile Infrastructure and Portfolio Businesses segments, as well as for Group Common and Other.

Reported or comparable results for the Nokia Group were not affected by the changes in the reporting structure.
