Relating mainly to our interests in Porthos and German LNG, the investments in 2025 were needed for the further development of the new-build projects CCS (Porthos) and LNG terminal (German LNG). The direct movements in equity referred to the remeasurement of our interest in Gate terminal as a consequence of the change in fair value of the effective part of Gate terminal’s cash flow hedge. We have recognised this direct change in equity in other comprehensive income.
The loans to joint ventures relate to making loan facilities available to EemsEnergyTerminal and VertiCer. For more information on this matter, see note 41 ‘Financial fixed assets’. Over the course of 2025, a total amount of € 12.0 million (2024: € 8.7 million) was drawn on these facilities, while € 0.4 million (2024: € 44.7 million) was repaid. These amounts are included in the consolidated statement of cash flows.
Of the joint ventures, Gate terminal, EemsEnergyTerminal and Porthos have a material effect (quantitative and/or qualitative) on our equity and our result.
