(“Atlantia” or the “Issuer”) may, from time to time, subject to compliance with all applicable laws, regulations and directives, issue debt securities in either bearer or registered form (respectively, “Bearer Notes” and “Registered Notes” and, together, the “Notes”) to be unconditionally and irrevocably guaranteed by Autostrade per l’Italia S.p.A. (“Autostrade Italia” or the “Guarantor”), Atlantia’s wholly-owned subsidiary (the “Guarantee”). The maximum aggregate nominal amount of all Notes from time to time outstanding under the Programme will not exceed €10 billion (or the equivalent in other currencies). The Notes may be issued on a continuing basis to one or more of the Dealers defined below or any additional Dealer appointed under the Programme from time to time, which appointment may be for a specific issue or on an ongoing basis (each a “Dealer” and together, the “Dealers”). References in this Offering Circular to the relevant Dealer, in the case of an issue of Notes being (or intended to be) subscribed by more than one Dealer, shall be to all Dealers agreeing to subscribe for such Notes. This Offering Circular is a “base prospectus” in accordance with Article 5.4 of Directive 2003/71/EC (the “Prospectus Directive”) as amended (which includes the amendments made by Directive 2010/73/EU (the “2010 PD Amending Directive”) to the extent that such amendments have been implemented in the relevant Member State of the European Economic Area). The Offering Circular has been approved by the Central Bank of Ireland (the “Central Bank”), as competent authority under the Prospectus Directive. The Central Bank only approves this Offering Circular as meeting the requirements imposed under Irish and EU law pursuant to the Prospectus Directive. Such approval relates only to the Notes which are to be admitted to trading on the regulated market of the Irish Stock Exchange or other regulated markets for the purposes of Directive 2004/39/EC or which are to be offered to the public in any Member State of the European Economic Area (each, a “Member State”). Application has been made to the Irish Stock Exchange for Notes issued under the Programme to be admitted to the Official List and trading on its regulated market. Notice of the aggregate nominal amount of Notes, interest (if any) payable in respect of the Notes, the issue price of the Notes and any other terms and conditions not contained herein which are applicable to each Tranche (as defined under “Overview of the Programme”) of Notes issued under the Programme will be set out in final terms (the “Final Terms”) which, with respect to Notes to be listed on the Irish Stock Exchange, will be filed with the Central Bank. The Programme provides that Notes may be admitted to listing on such other or further stock exchanges as may be agreed upon by and between the Issuer, the Guarantor and the relevant Dealer. The Issuer may also issue unlisted Notes. Where Notes issued under the Programme are admitted to trading on a regulated market within the European Economic Area or offered to the public in a Member State of the European Economic Area in circumstances which require the publication of a prospectus under the Prospectus Directive, such Notes will not have a denomination of less than €100,000 (or, in the case of notes that are not denominated in euro, the equivalent thereof in such other currency). Investing in the Notes involves risks. Please see the section entitled “Risk Factors” beginning on page 7.

Subject to certain exceptions, the Notes may not be offered or sold or, in the case of Bearer Notes, delivered in the United States or to, or for the account or benefit of, U.S. persons (as defined in Regulation S under the Securities Act (“Regulation S”) in the case of Registered Notes, or as defined in the U.S. Internal Revenue Code of 1986, as amended, and regulations thereunder in the case of Bearer Notes). See “Forms of the Notes” for a description of the manner in which Notes will be issued. Registered Notes are subject to certain restrictions on transfer.
