Risks to understand before you invest
An investment in Algene involves the risk of losing some or all of the amount invested. Selling the investment may be difficult, and you may receive less than you paid. The offering documents explain the specific risks.
Early stage
Series production started in July 2026. Algene does not yet report revenue. Revenue status – confirm.
Customers
So far there are non-binding letters of intent and a planned first delivery. Delivery status – confirm.
Fresh format
Fresh paste has to be kept cold and contains water, so it is heavier to ship than powder. This adds cost, and some buyers may still prefer powder. Storage and shelf life – confirm.
Largest shareholder
DN Group AG holds 45.56 % and provides part of the funding. DN's own 2026 prospectus describes its holdings as young businesses that could fail completely.
Selling
Algene shares trade with very little turnover. Bond transferability – confirm.
Ranking and security
How the investment ranks and whether it is secured, from the offer terms – add.
