Change to the definition of service revenue. Since January 1, 2026, certain wholesale voice transit revenues have no longer been included in service revenues due to their unpredictable or non-recurring nature. Instead, they are recognized under non-service revenues. Prior-year comparatives in both of the affected segments, Germany and Europe, were adjusted retrospectively.
