Regulatory News:

Aéroports de Paris (Paris:ADP) (Pink Sheets:AEOPF) is holding today an investor day dedicated to institutional investors and sell-side analysts. The main objectives of this day are:

• To present the strategic orientations of the new 2011-2015 regulation framework
• To present the Group's targets by 2015 in terms of economic performance and quality of service
• To detail the 2011-2015 retail and real estate strategy, growth levers and targets by 2015.

An EBITDA growth target of +40% between 2009 and 2015

Aéroports de Paris intends to pursue an investment strategy on its core business in order to improve the quality of service and to increase the attractiveness of its airports while intensifying its productivity efforts. At the same time, the Group will continue to develop its retail and real estate activities.

Thanks to this strategy and based on a traffic growth assumption of +3.2% on average per year over the period 2011-2015 (0% in 2010, +2.0% in 2011, +2.4% in 2012, +3.9% in 2013, 2014 and 2015), the Aéroports de Paris Group targets to improve the EBITDA by 40% between 2009 and 2015.

Ambitious retail targets

Aéroports de Paris intends to pursue its strategy of retail development by implementing 4 levers:

• To continue to increase surfaces dedicated to retail
• To improve the organisation of retail areas
• To expand retail offer
• To drive towards operating excellence.

Aéroports de Paris targets to increase retail surfaces by 21% between 2009 and 2015, including an increase of shops in restricted areas by 35% and to reach sales per passenger of €17.4 in the shops in restricted areas by 2015.

Continued development of real estate

With 446 hectares of available land reserves, real estate is at the heart of the development strategy of Aéroports de Paris. Aéroports de Paris is aiming at becoming a top landholding trust exploiting the potential of development provided by the airport and the proximity of Paris by implementing 3 levers:

• To maintain a role of land servicer and reinforce that of investor
• To develop several product segments,
• To invest independently or in partnership depending on the project.

Aéroports de Paris targets to develop, independently or in partnership, between 320,000 m² and 360,000 m² of buildings by 2015, including approximately 75% dedicated to diversification real estate. The main projects in progress are the development of a shopping mall at Paris-Charles de Gaulle (Aéroville), Roissypole and Cœur d'Orly.

The corresponding investments borne by Aéroports de Paris would be between €500m and €560m, including €430m to €480m dedicated to diversification real estate.

A new Economic Regulation Agreement geared towards quality of service

On 23 July 2010, Aéroports de Paris signed the 2011-2015 Economic Regulation Agreement (ERA) with the French State. The main points of the agreement are:

• An investment plan amounting to €1.8bn on the regulated perimeter (€2.4bn at the parent company level). This plan, will focus in particular on the continuation of the construction of satellite 4 and the refurbishment of the oldest terminals and includes a budget dedicated to quality of service for targeted operations with strong lever effect
• The implementation of 10 indicators linked to quality of service with ambitious targets and associates with incentives in the form of bonuses and penalties. 5 of these directly measure passenger satisfaction
• A moderate pricing cap (average of 1.38 % per year above inflation), alongside an adjustment factor to partially compensate for the difference noted in traffic.

Aéroports de Paris targets to significantly improve the quality of service on the platforms and to reach in 2015 the top of the range defined by the ERA for overall satisfaction, i.e. a rate of 88.1%.

A change in regulated perimeter that creates long term value

This agreement takes into account an adjustment to the company’s regulated perimeter, applicable from 1st January 2011: as of this date, diversification real estate1 and commercial activities2 will no longer be included in the regulated perimeter. The change in the regulated perimeter, which creates value over the long term, represents a dual incentive to develop traffic, both within the regulated perimeter and within the non-regulated perimeter.

The exclusion of the commercial and diversification real estate activities, which are highly profitable, will automatically result in lowering the return on the regulated perimeter. Aéroports de Paris targets to progressively restore the profitability of the regulated perimeter thanks to the anticipated growth in traffic, moderation of investments and productivity gains aimed at stabilising the costs per passenger3 between 2010 and 2015. Consequently, the 2011-2015 ERA must be seen as a transition phase: the return on capital employed within the regulated scope should be in line with the company's weighted average cost of capital on average over the following ERA (2016-2020).
