Based on the results of the shareholders' register, supplemented by the notices of significant holdings pursuant to art. 120 Consolidated Act and from the information available, the following table summarises the composition of the Iren shareholder base. Special consideration has been given to the holdings of members with more than 3% voting shares.

Excerpts from the published Shareholders' Agreement and Sub Agreements, containing all the information required by applicable regulations, can be found in the documents below.

The introduction of increased voting is aimed at achieving loyalty and stability in the shareholding structure and is associated with the amendments to company law introduced by article 20 of Decree Law 91 of 24 June 2014 ("the competition decree").

Increased voting are attributed to the shares held by the same shareholder for at least 24 months and for which registration in a suitable list has been requested. The application for registration cannot be received directly from the shareholder, but must be made by the intermediary at which the shareholder maintains the securities account where the Iren shares are deposited.
