Press Release

TIM: the content offer is strategic, the creation of a JV moves forward

The Board has acknowledged the expiry of the term sheet and that fresh negotiations will follow the regulations governing related-party transactions of greater importance

Milan, 17 January 2018

TIM’s Board of Directors acknowledged that the term sheet signed with Canal+ will expire on 18 January without the signing of definitive joint venture agreements between the parties. Accordingly, the approval resolutions made on 20 October and 5 December 2017 will become obsolete.

Negotiations aimed at finalizing a collaboration agreement between TIM and Canal+ in the content sector, to support telco and media convergence programmes, will restart immediately, with the goal of reaching a rapid conclusion. The joint venture has the objective to offer TIM customers video content through the acquisition and production of television content and to manage its related services.

The convergent offer of video content is one of the key elements of TIM’s 2018-2020 strategic plan.

In light of the indications from Consob, and in keeping with the observations made at the time by the Company’s Board of Statutory Auditors, the regulations governing related-party transactions of greater importance will now be applied to the project - which qualifies as a related-party transaction in that Vivendi indirectly controls Canal+ International S.A.S. and is also the main shareholder and de facto controlling company of TIM (according to the opinion reached by Consob), as well as exercising direction and coordination activities. Consequently, a special Committee made up of all the independent directors of the Board will be involved in the new negotiations and this Committee, presided over by the Chair of the Control and Risk Committee (Professor Calvosa), will be required to express a binding opinion on the interest, convenience and appropriateness of the conditions of the agreement.

Cautionary Statement for Purposes of the “Safe Harbor” Provisions of the United States Private Securities Litigation Reform Act of 1995.

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements. The Group’s interim report as of and for the nine months ended September 30, 2017 included in this Form 6-K contains certain forward-looking statements. Forward-looking statements are statements that are not historical facts and can be identified by the use of forward-looking terminology such as “believes,” “may,” “is expected to,” “will,” “will continue,” “should,” “seeks” or “anticipates” or similar expressions or the negative thereof or other comparable terminology, or by the forward- looking nature of discussions of strategy, plans or intentions.

Actual results may differ materially from those projected or implied in the forward-looking statements. Such forward-looking information is based on certain key assumptions which we believe to be reasonable but forward-looking information by its nature involves risks and uncertainties, which are outside our control, that could significantly affect expected results.

The following important factors could cause our actual results to differ materially from those projected or implied in any forward-looking statements:

our ability to successfully implement our strategy over the 2016-2018 period;

the continuing effects of the global economic crisis in the principal markets in which we operate, including, in particular, our core Italian market;

the impact of regulatory decisions and changes in the regulatory environment in Italy and other countries in which we operate;

the impact of political developments in Italy and other countries in which we operate;

our ability to successfully meet competition on both price and innovation capabilities of new products and services;

our ability to develop and introduce new technologies which are attractive in our principal markets, to manage innovation, to supply value added services and to increase the use of our fixed and mobile networks;

our ability to successfully implement our internet and broadband strategy;

our ability to successfully achieve our debt reduction and other targets;

the impact of fluctuations in currency exchange and interest rates and the performance of the equity markets in general;

10.

the outcome of litigation, disputes and investigations in which we are involved or may become involved;

11.

our ability to build up our business in adjacent markets and in international markets (particularly in Brazil), due to our specialist and technical resources;

12.

our ability to achieve the expected return on the investments and capital expenditures we have made and continue to make in Brazil;

13.

the amount and timing of any future impairment charges for our authorizations, goodwill or other assets;

14.

our ability to manage and reduce costs;

15.

any difficulties which we may encounter in our supply and procurement processes, including as a result of the insolvency or financial weaknesses of our suppliers; and

16.

the costs we may incur due to unexpected events, in particular where our insurance is not sufficient to cover such costs.

The foregoing factors should not be construed as exhaustive. Due to such uncertainties and risks, readers are cautioned not to place undue reliance on such forward-looking statements, which speak only as of the date hereof. We undertake no obligation to release publicly the result of any revisions to these forward-looking statements which may be made to reflect events or circumstances after the date hereof, including, without limitation, changes in our business or acquisition strategy or planned capital expenditures, or to reflect the occurrence of unanticipated events.
