Société Générale — Earnings Release 2009

Jul 6, 2009

Press Release

Paris, 6 July 2009

Estimated results for the second quarter of 2009

The Group second quarter 2009 results will be published on 5 August. Net Income is expected to be slightly positive. Solid operational performances, in particular in Corporate & Investment Banking, will absorb the significant negative impact on the accounts of the substantial tightening of credit spreads stemming from an improving market environment and reduced aversion to risk since mid-March. Overall, the Group's net banking income is expected to register an estimated 1.3 billion euro negative impact from CDS used to hedge its loan portfolio and from debt instruments issued by the Group and booked at fair value.

The cost of risk is expected to reach a level comparable to its level in Q1 09. The impact of assets at risk should be limited. In the mean time, the Group continues to reduce its exposures.

The Group's Tier One and Core Tier One ratios are expected to be close to their levels at 31 March 2009 pro-forma of the issuance of preference shares to the French State (1).
