Business concentrations – EU and Polish rules
Publication date: January 21, 2026
Business concentrations are common and significant phenomena that constitute a part of modern economic activity. They include takeovers, mergers, the acquisition of assets, and even the creation of joint ventures. Their primary goal is typically to develop companies and increase competitiveness and efficiency. They can also lead to a restriction of market competition. Therefore, the legislature has introduced the obligation to notify the President of the Office of Competition and Consumer Protection (UOKiK) of any intended concentration in cases where it may affect competition conditions in Poland. This article will discuss when an enterprise must notify the President of the Office of Competition and Consumer Protection (UOKiK), what information should be included, and the procedure conducted by the President of the UOKiK.
