Abstract
Exceeding specific shareholding thresholds in a public company gives rise to certain notification duties (notification thresholds) for the investor. Notification thresholds adopted by the Polish legislator arouse significant doubts as to their compliance with the provisions of (implemented) EU directives and their usefulness in the context of the functions to be performed by individual thresholds. It is not without significance where a given threshold has been established. The aim of this article is to discuss the most important controversies concerning the thresholds adopted in Poland, also in the context of new regulations introduced by the Act of 16 October 2019 amending the Act on Public Offering, Conditions for the Introduction of Financial Instruments to an Organised Trading System, and Public Companies and certain other acts.
