Where this data comes from

The structure is built from notifications shareholders file after crossing 5%, 10%, 15%, 20%, 25%, 33%, 50%, 75% and 90% of votes.

Below 5% there is no disclosure obligation, so the remaining capital is shown collectively as free float — its composition is not publicly known.

Stakes are not updated in real time. The date next to each entity is its last notification date, not today's date.

The share count behind every percentage comes from the newest (by as-of date) periodic report or art. 69 notification — not from the company's GPW/NewConnect profile.
