1. The proforma Net Debt considers the impact of the future payment to be received for the sale of ACEA Energia to Eni Plenitude (considering the enterprise value included in the binding offer of €460m, the recognised net cash of €128.5m vs a reported net cash of €213.9m as at 31st December 2024, as well as net cash changes occurred in the first semester of 2025 and the net financial position reclassified among the "Discontinued Operation") and the sale price of the High Voltage grid to Terna for €224m (assuming that ARERA's premium of €23m is received in 2026).
