04 Notes to the key financial figures

Reported revenues are over € 200 million higher than last year, mainly due to increased 2026 tariffs of GTS. This increase is primarily driven by (i) higher revenues resulting from several regulatory settlement adjustments and (ii) a reduction in the expected volume of gas transportation capacity to be sold. Next to this we see a further decline of contracted capacities in The Netherlands and Germany.

As reported operating expenses are in line with the previous year, EBITDA shows a positive development compared to the first half of 2025.

The underlying EBITDA is approximately € 40 million higher compared to first half year 2025, mainly driven by revenue effects.
