Roma 22 November, 2016 – As part of the Acea Group’s growth strategy, which envisages, among other things, consolidation of the Company’s presence in the water sector, Acea announces that it has entered into preliminary agreements – not included in the targets set out in the Business Plan for 2016-2020 but among the initiatives already under consideration – for the acquisition:

- from the Veolia Group, of 100% of Idrolatina, which in turn holds a 49% interest in Acqualatina, for a price of €22m. The remaining 51% of Acqualatina is owned by municipalities in the ATO4 – Southern Lazio concession area;

- from the Veolia Group, of 19.2% of Gestione Esercizio Acquedotti Lucchesi - GEAL for a price of €2m. Acea already owns 28.8% of GEAL through Crea SpA, thus raising its stake in GEAL to 48%;

- from the Severn Trent Plc Group, of 100% of Severn Trent Italia and, indirectly, 64% of Umbriadue Servizi Idrici and 80% of Iseco, for a price of €0.4m. As Acea already owns 34% of Umbriadue Servizi Idrici through Crea Gestioni Srl, the acquisition will thus raise its stake in Umbriadue to 98%.

Completion of the above transaction is subject to the usual conditions precedent for similar transactions.
