Company transformations are legal processes aimed at changing the legal or organizational structure of a company without terminating its business activities. The main forms of transformations include mergers, demergers, change of legal form, transfer of assets to a shareholder, and cross-border transformations.

Company transformations are typically used in the context of corporate group restructurings, separation of business activities, succession planning, preparation for a company sale, or to ensure more efficient management. In the case of cross-border transformations, emphasis is placed on harmonizing the legal frameworks of the involved states and compliance with European legislation.
