DESCRIPTION OF THE SHARE BUY-BACK PROGRAMME
AUTHORISED BY THE COMBINED GENERAL MEETING DATED 20 MAY 2025

This description is drawn up in accordance with the provisions of Article 241-2-I of the General Regulation of the French Financial Markets Authority (“Autorité des marches financiers”) and is available below.

1. Purposes of the share buy-back programme
The Combined General Meeting dated 20 May 2025, by its 19^th resolution, has renewed Societe Generale’s authorisation to buy its own shares so it can:

• grant, cover and honour any free shares allocation plan, employee savings plan and any form of allocation for the benefit of employees and company officers of the Company or affiliated companies under the conditions defined by the applicable legal and regulatory provisions;
• cancel them;
• deliver shares upon the exercise of rights attached to securities giving access to the Company’s share capital;
• hold and subsequently deliver shares as payment or exchange as part of Group’s external growth transactions such as merger, spin-off or asset contribution transactions;
• allow an investment services provider to trade in the Company’s shares as part of a liquidity agreement compliant with the regulations of the French Financial Markets Authority (“Autorité des Marchés Financiers”).

2. Maximum amount allocated to the share buy-back programme, maximum number and characteristics of shares, maximum purchase price
The resolution approved by the General Meeting provides that Societe Generale can purchase its ordinary shares up to 10% of the total number of shares.
Within the framework of the share buy-back programme authorised by the Combined General Meeting and given the current share capital, the Company could purchase a theoretical maximum number of 76,689,478 shares representing 10% of its share capital.
The maximum purchase price having been set by the said Assembly at EUR 75 per share, the potential maximum amount allocated to the programme is EUR 5,751,710,850.
This maximum amount is likely to change in case of transactions impacting its share capital. In addition, in application of the regulation, the number of shares directly owned by Societe Generale may not exceed, at any time, 10% of the share capital. Thus, at midnight (Paris time) on November 20, 2025, Societe Generale directly owning 2,407,225 ordinary shares, representing 0.3% of its share capital, Societe Generale may acquire on the date of this description 74,282,253 shares representing 9.7% of its share capital, i.e. a maximum theoretical amount to date of EUR 5,571,168,975 based on the maximum repurchase price of EUR 75 per share.

3. Duration of the share buy-back programme
The Combined General Meeting dated 20 May 2025 has set the duration of the authorisation for the Company to buy its own shares at 18 months from the date of the General Meeting, i.e. until 20 November 2026.

4. Fulfillment of prudential requirements
The Board of Directors will ensure that the execution of these buy-backs will be carried out in accordance with prudential requirements as defined by the regulation and the European Central Bank.
