• The first half 2026 reported revenue is the first without the negative impact of early access rebates
• Reported revenue does not include royalties to be received from commercial partners on Sibnayal® sales
• In the French market alone, Sibnayal® sales grew by 41% in volume
• Reimbursement of Likozam® has high impact on its sales growth

Paris, France, July 16, 2026 – 5.45PM (CET) – Advicenne S.A. (“Advicenne” or the “Company”) (Euronext Growth Paris - FR0013296746 - ALDVI), a pharmaceutical company specializing in the development and marketing of innovative treatments for people suffering from rare kidney diseases, today announces its net revenue for the first half of 2026, more than doubled to €2.7 million, the first one reported without the significant negative impact of the early access clawbacks. The reported revenue does not include royalties to be received from its commercial partners on Sibnayal®’s sales.

The very significant increase in activity over the past half-year is explained by the pricing agreements for both Sibnayal® and Likozam® reached during the period. These agreements put an end to the early access rebates (clawback) which, as a reminder, amounted to €1.6 million in the first half of 2025.

Since Sibnayal® and Likozam® gained reimbursement in France, sales of both products are accelerating, growing by 41% and 13% respectively in volume, reflecting the enlarged and easier access to treatments.

Lastly, estimated in-market Sibnayal® sales across all markets where it is marketed totaled €6.6 million in the first half of 2026, up 27% compared with the first half of 2025, reflecting the steady increase in the number of patients treated. The royalties associated with these sales will be received by Advicenne during the third quarter of 2026.

As of the date of this press release, the Company has a cash runway through the second quarter of 2027, thanks to the bond financing announced on June 22, as part of the safeguard proceedings (“Procédure de sauvegarde”).
