Officers
2
Two officers are currently on record for BIOWATT S.A., filed with National Court Register (KRS). Piotr Mularewicz serves as Independent Director; Tomasz Kajdan serves as Vice President Of The Management Board.
Management authority at BIOWATT S.A. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
BIOWATT S.A. has no recorded parent company — it sits at the top of its own group structure, with 2 subsidiaries recorded beneath it across 1 jurisdiction. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 2 subsidiaries span Poland jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
