DEINOVE : Third convening to an Extraordinary General Meeting on July 5, 2022

DEINOVE (Euronext Growth Paris: ALDEI), a French biotech company, pioneer in the exploration and exploitation of bacterial biodiversity to address the urgent, global challenge of antibiotic resistance, informs its shareholders that the combined Annual General Meeting (AGM) held on May 30, 2022 was unable to deliberate on extraordinary resolutions, as the required quorum was not reached on second convening, and that a new Extraordinary AGM will be held on July 5, 2022 at 2 p.m. CEST, in the premises of Fieldfisher, 48 rue Cambon, 75001 Paris, to deliberate on the same agenda.

A third convening notice will be published on June 24, 2022 in the BALO and in a legal newspaper.

At the Company's request, the President of the Commercial Court of Montpellier appointed, by order dated June 20, 2022, Maître Vincent AUSSEL, as ad hoc representative (mandataire ad hoc) to represent and act on behalf of the defaulting shareholders at the General Meeting so that the quorum is reached. It is specified that the voting rights attached to the shares of the defaulting shareholders shall be exercised by the ad hoc representative in compliance with the Company's interest, and at the rate of two-thirds votes in favor and one-third votes against, which would result in the participation of the ad hoc representative being "neutral" in terms of qualified majority.

All the documents regarding this AGM will be available on the Company's website as from June 24, 2022: https://www.deinove.com/en/investor-room/documentation-center/general-shareholders-meeting-preparatory-documents
