(7)There are substantial differences between national provisions for MVS structures across Member States. Some Member States allow MVS structures, while others ban them. In some Member States, such a ban is limited to public companies, while in others it applies to all companies. The differences in national regimes create barriers to the free movement of capital within the internal market and create an uneven playing field for companies in different Member States. Companies in a Member State that bans MVS structures have to move to another Member State or even outside the Union, thereby facing higher costs, if they want to adopt an MVS structure with a view to seeking admission to trading of their shares on a market. In some cases, because of those higher costs, companies might decide not to raise funds from the public, which might limit their funding opportunities. Such considerations are particularly relevant for SMEs and start-ups that lack financial resources to cover those costs.
