Credit institutions shall, on becoming aware of any acquisitions or disposals of holdings in their capital that cause holdings to exceed or fall below one of the thresholds referred to in Article 22(1) and Article 25, inform the competent authorities of those acquisitions or disposals.

Credit institutions admitted to trading on a regulated market shall, at least annually, inform the competent authorities of the names of shareholders and members possessing qualifying holdings and the sizes of such holdings as shown, for example, by the information received at the annual general meetings of shareholders and members or as a result of compliance with the regulations relating to companies admitted to trading on a regulated market.

Member States shall require that, where the influence exercised by the persons referred to in Article 22(1) is likely to operate to the detriment of the prudent and sound management of the institution, the competent authorities shall take appropriate measures to put an end to that situation. Such measures may consist in injunctions, penalties, subject to Articles 65 to 72, against members of the management body and managers, or the suspension of the exercise of the voting rights attached to the shares held by the shareholders or members of the credit institution in question.

Similar measures shall apply to natural or legal persons who fail to comply with the obligation to provide prior information as set out in Article 22(1) and subject to Articles 65 to 72.

If a holding is acquired despite opposition by the competent authorities, Member States shall, regardless of any other penalty to be adopted, provide either for exercise of the corresponding voting rights to be suspended, or for the nullity of votes cast or for the possibility of their annulment.
