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.
