SHAREHOLDERS’ INFORMATION

Changes to the procedures for convening general meetings

Decree no 2026-94 of February 13, 2026, regarding the modernisation of procedures for communicating with shareholders, has amended certain rules applicable to the convening of general meetings.

From now on, in order to participate and vote at the Meeting, shares must be registered in an account no later than midnight (Paris time) on the fifth business day preceding the General Shareholders’ Meeting, as opposed to two business days prior.

Registered shareholders who currently receive notice of the General Shareholders’ Meeting by post each year will, starting in 2027, receive their notices for General Shareholders’ Meetings via email. It is therefore essential that Uptevia have a valid email address for each shareholder. We therefore invite you to provide us with your email address now, using one of the methods described on page 83 of this notice of meeting.

Furthermore, the documents that were previously attached to the notice of meeting will no longer be sent by post, as they will be available on the Company’s website: www.publicisgroupe.com.
