Acquisition of the minority stake in International Power: a reinforcement in GDF SUEZ strategic ambition

Yesterday, the International Power independent board members unanimously approved the revised offer made by GDF SUEZ for the 30% stake it does not already own in International Power. The revised offer price is 418 pence per share¹ and has been approved by the Board of GDF SUEZ.

This transaction will be structured as a "Scheme of Arrangement" under the UK regulatory framework, which facilitates a shorter timetable with a targeted closing date mid-July 2012. In case of a favourable vote from International Power minority shareholders, GDF SUEZ will own 100% of International Power shares.

This transaction represents a major strategic step in GDF SUEZ's development. It is consistent with the Group's strategy of accelerating its development in fast growing markets and simplifying its structure.

It enables GDF SUEZ to take the full control of a unique platform for development in fast growing countries, where the Group intends to significantly increase its investments in the future. International Power has leading positions in regions supported by steady energy demand such as South America, the Middle East, South-East Asia and Australia.

Following this transaction, the Group will revise upward its capex guidance within fast growing markets to 40%-50% of the Group's total gross capex in the medium term (versus 30% today), thereby fostering the 90GW installed capacity target out of Europe by 2016.

The transaction will also enable GDF SUEZ to receive the full benefit of the synergies generated from the combination of GDF SUEZ and International Power which closed in February 2011.

Regarding the impact on earnings, on a pro-forma basis for 2011, the transaction will be earning per share accretive by 9%, from €1.8 to €2.0 before taking account of additional disposals and scrip dividend. The Group's 2011² pro forma net debt impact is expected to be €8.4bn, and should be partly mitigated by the opportunity offered to GDF SUEZ shareholders to participate in the scrip dividend option for the 2011 final dividend and any 2012 interim dividend to be proposed.

It is worth noting that the French State and the GBL Group have already committed to elect for the scrip dividend option for these two dividend payments. In addition, the Group is committed to realising €3bn of additional disposals. The disposal plan will meet the Group's strategic objectives of an increased presence in fast growing markets as well as an enhanced integration of its European activities.

¹ 2011 final dividend of €6.6 cents per share being paid at scheduled date to International Power shareholders.

² i.e. 5% after taking into account the undertaking of the two largest shareholders to subscribe to the scrip dividend and before additional disposals.

Following this transaction, GDF SUEZ confirms its objective to maintain an "A" category rating and its dividend policy. The 2012 net recurring income Group share³ target is revised upwards by c.€200m in the range of €3.7-4.2bn 4 (vs. €3.5-4.0bn announced on 9th February 2012), due to the full integration of International Power in the second semester. For the full year 2013, the increase will amount to c.€400m, before additional disposals. The transaction post share dividend and post additional disposals is earnings per share accretive going forward⁵ .

Gérard Mestrallet, Chairman and CEO of GDF SUEZ commented: "The acquisition of the minority stake in International Power, based on a strict financial discipline, constitutes a major step in the development of the Group. It will allow the Group to fully capture growth in fast growing markets. The transaction is accretive on earnings for shareholders and also establishes the basis of a long term and solid growth. We want GDF SUEZ to be the leading energy player in the emerging countries."
