Launch of a share buyback program

Paris, 7th November 2022 – As part of Ipsos' 4-year plan, which was announced both in a press release and during its Investor Day presentation on 14 June, 2022, the Company's priorities in the area of capital allocation and the return of value to shareholders include the launch of a new share buyback program of up to 2% of the share capital per year subject to market conditions.

This program comes on top of Ipsos' existing annual share repurchases implemented to compensate for the dilution from Ipsos' free share and option plans for managers and employees.

To this end, the Company will proceed, between now and 28 December 2022, with a first tranche of share repurchases with a view to their cancellation, up to an amount of approximately 10 million euros, corresponding to approximately 0.5% of its share capital at the closing price on 4 November 2022 (47.85 euros), in accordance with the terms and conditions of the authorizations granted by the Combined General Meeting held on 17 May 2022 (Resolutions 23 and 24).

Ipsos reserves the right to suspend the program at any time depending on market conditions or the implementation of its investment strategy.

A description of this share buyback program is available on the Company's website (www.ipsos.com) in the section entitled "Investors", and in the subsection relating to regulated information.
