Ownership structure

The company from the directory is at the top. Below it are the entities registered as its shareholders, and below them their owners, up to three levels.

An arrow points to the company in which the owner holds shares. Hover over or tap an arrow to see the registry entry date. A two-way arrow marks cross-shareholding.

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 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, 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.

Shareholder history

REGON reports only the current state, so the bar starts at the first reading, on 23-09-2026.

In a limited liability company KRS lists shareholders holding at least 10% of the share capital, so an exit may also mean that the shareholder's stake fell below that threshold.

Cyber Katalog presents the shareholder history from the full extract of 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.
