Ownership structure

A tile with a dashed border stands for shareholders who are natural persons, given only as a number, without names.

A line marked REGON is the ownership form that Statistics Poland reports for that entity.

Hovering over or tapping a company usually shows its NIP, REGON and KRS numbers, and the LEI number for a company from the GLEIF index. The card does not appear for the State Treasury or a family foundation.

Cyber Katalog presents ownership data from the National Court Register (KRS), and the ownership form from the REGON register kept by Statistics Poland.

We take no responsibility for the accuracy, completeness or timeliness of that information.
