DOCUMENTS INCORPORATED BY REFERENCE The following information has been filed with the Central Bank and shall be deemed to be incorporated by reference into the Offering Circular and shall supplement the section entitled “Incorporation by Reference” in the Offering Circular on page 26 thereof: (a) a press release entitled “Board approves Autostrade per l’Italia group’s interim report for six months ended 30 June 2016”1, available at: http://www.autostrade.it/en/investor-relations/comunicati-stampa- finanziari?p_p_id=comunicatiinvestor_WAR_comunicatiportlet&p_p_lifecycle=2&p_p_state =normal&p_p_mode=view&p_p_resource_id=downloadAttachment&p_p_cacheability=cach eLevelPage&p_p_col_id=column- 1&p_p_col_count=1&_comunicatiinvestor_WAR_comunicatiportlet_id=1367&_comunicatii nvestor_WAR_comunicatiportlet_jspPage=%2Fhtml%2Finvestor%2Fview.jsp&_comunicatii nvestor_WAR_comunicatiportlet_action=viewDetail&_comunicatiinvestor_WAR_comunicat iportlet_itemId=1002 1 Reference to “audited” on pages 2 and 11 of the press release is as a result of translation issues and should instead be taken to mean “limited review”. 2 ADDITIONS TO THE OFFERING CIRCULAR Credit rating On 23 May 2016, Fitch confirmed its ‘A-’ rating and stable rating outlook in respect of Autostrade Italia. On 21 July 2016, Moody’s confirmed its ‘Baa1’ rating and stable rating outlook in respect of Autostrade Italia. Recent Developments The information set out below shall supplement the section of the Offering Circular entitled “Business Description of the Group — Recent Developments” and shall be deemed to be incorporated in the Offering Circular in its entirety at page 63. Preliminary traffic figures for the six months ended 30 June 2016 Preliminary traffic figures for the network operated under concession by Autostrade Italia show growth of 3.7% in the first six months of 2016, compared with the same period of 2015. Issuer Substitution and Transfer The boards of directors of Autostrade Italia and Atlantia S.p.A. (“Atlantia”) on 10 July 2016 approved a plan to “ring fence” the debt of Autostrade Italia by 2025 via: under the seven series of notes issued in public syndicated transactions by Atlantia (the “Public Notes”) under its Euro 10,000,000,000 EMTN Programme guaranteed by Autostrade Italia (the “Atlantia Programme”), the substitution as issuer of Autostrade Italia in place of Atlantia as the principal debtor, and the provision of a guarantee by Atlantia (the “Issuer Substitution”); and under the six series of notes issued under the Atlantia Programme on a private placement basis (the “Private Notes”) the substitution as issuer of Autostrade Italia in place of Atlantia, the provision of a guarantee by Atlantia until 2025 and various amendments to the terms and conditions (the “Transfer”). In addition, if the Issuer Substitution and the Transfer are effected, Autostrade Italia and Atlantia propose to terminate the intra-group financing arrangements which were initially entered into in relation to the Public Notes and the Private Notes. In respect of the Public Notes, Atlantia intends to implement the Issuer Substitution pursuant to the terms of the relevant trust deeds of the Atlantia EMTN Programme. In respect of the Private Notes, the intention of Autostrade Italia and Atlantia is to execute the Transfer by way of amendments to each series of Private Notes. Atlantia would require the consent of the holder(s) of all series of Private Notes. In addition, Autostrade Italia and Atlantia propose to make various other changes to align the terms and conditions of the Private Notes more closely with those of the notes issued recently by Autostrade Italia under the Programme, including to the cross default provision. Therefore after 2025, if the Issuer Substitution and Transfer are implemented, “ring fencing” will have been achieved because: (i) all of the Public Notes will have matured; (ii) Atlantia will no longer guarantee any of the series of Private Notes; and (iii) the amendments to the terms and conditions of the Private Notes will permit Autostrade Italia to have the same terms and conditions across all series of notes, whether originally issued by Atlantia or Autostrade Italia. 3 There can be no assurance that the Issuer Substitution or the Transfer will be completed in the manner set forth above or at all. The notes issued by Atlantia and distributed to Italian retail investors in 2012, which are due to mature in 2018, will not be affected by the Transfer or the Issuer Substitution. None of the notes issued by Autostrade Italia will be affected by the Transfer or the Issuer Substitution. Management The information set out below shall replace in its entirety the section of the Offering Circular entitled “Management — Board of Directors” at pages 75 and 76. The Board of Directors of Autostrade Italia (the “Board of Directors”) is composed of seven members. The current members of the Board of Directors were elected on 21 April 2016 and will hold office until the shareholders’ meeting called for the approval of the financial statements for the year ending 31 December 2016.
