Ownership structure

A dashed line connects the company to a company from the directory with the same registered address, according to the list of VAT taxpayers. A shared address alone does not indicate ownership or personal ties.

A personal link means that the same person holds a position in both companies according to the KRS extracts. Cyber Katalog does not name that person, only the kind of position.

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), the ownership form from the REGON register kept by Statistics Poland, personal links from current extracts of the National Court Register (KRS), and registered addresses from the list of VAT taxpayers kept by the National Revenue Administration.

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