Incidental items

Alliander’s results can be affected by incidental items and fair value movements. Alliander defines exceptional items as items that, in the management’s opinion, do not derive directly from the ordinary activities and/or whose nature and size are so significant that they must be considered separately to permit proper analysis of the underlying results. In 2025, exceptional items had a positive impact of €70 million on our net profit. In 2024, exceptional items provided a gain of €779 million. This means that the net profit for 2025, adjusted for these exceptional items, was €22 million higher than in the previous year. The middle column in the table below shows the exceptional items, with an explanation below.

Reported figures and figures excluding incidental items and fair value movements

Other income

In April 2025, we sold the Randmeren high-voltage network to TenneT TSO B.V., resulting in a book profit of €30 million. In June 2025, we also transferred the free-domain transformers to Kenter, as agreed in the deal for the sale of Kenter in 2024. This resulted in a one-time book profit of €54 million.

The exceptional income in 2024 consisted of the proceeds from the sale of subsidiary Kenter B.V. in January 2024, amounting to €757 million, and €30 million in compensation received from the ACM for past removals of gas connections.

Tax

The income item of €14 million in 2025 and the income item of €8 million in 2024 are due to the impact of the aforementioned exceptional items on corporate income tax. Pursuant to the Dutch substantial shareholding exemption regime, the proceeds from the sale of the Randmeren high-voltage grid in 2025 and the sale of the Kenter shares in 2024 are exempt from corporate income tax.
