Brussels, March 6, 2026, 5.45 pm CET

Solvac proposes to its shareholders the option of choosing dematerialized shares in addition to registered shares, the removal of the approval procedure for legal entities, and the granting of double voting rights on each registered share held for at least two years.

At its next Extraordinary General Meeting on 12 May 2026, Solvac will propose to shareholders an amendment to its Articles of Association, effective 1 October 2026, consisting of:

• authorizing each shareholder to hold all or part of their shares in dematerialized form,
• removing the requirement for prior approval of legal entities,
• granting a second voting right to each registered share held by the same shareholder for an uninterrupted period of two years.

These initiatives are intended to:

• allow each shareholder to choose the form of share they wish to hold, while promoting shareholder stability,
• grant a second loyalty voting right to shareholders who, through Solvac, provide long-term support for the strategic and industrial vision of its holdings, and
• attract new shareholders who see Solvac as a company committed to creating sustainable value.

Dematerialized shares and free holding

The dematerialized form will coexist with the registered form of Solvac shares. In dematerialized form, Solvac shares may be freely traded on Euronext Brussels between natural persons, legal entities and/or similar entities, without prior approval from the Board of Directors. This measure is intended to facilitate the trading of securities and enable a wider range of investors to hold Solvac shares.

Double voting rights

The two-year period for obtaining a second voting right will begin to run from the date of registration of the registered shares in Solvac's register, even if this took place before the adoption of double voting rights by the Extraordinary General Meeting. In case of a conversion of their shares by a shareholder into dematerialized ones, the double voting right will be lost.
