| B. | Suspension of the share buyback program |
Materialise today announces that the program is suspended following trading on 25 July 2026.
The suspension is required because the authorization underlying the program cannot be renewed during the applicable closed period. As a result, the Company will not conduct any share repurchases during this suspension period.
Subject to the renewal of the authorization and compliance with all applicable legal and regulatory requirements, the Company currently intends to restart the share buyback program on 31 August 2026.
The Company will issue a further press release to confirm the restart of the program once the relevant conditions have been satisfied and share repurchases effectively recommence.
This announcement does not constitute an obligation to resume the share buyback program on any particular date. Any restart of the program will remain subject to the necessary corporate approvals, market conditions and applicable legal and regulatory requirements.
