Activist stake amendment (position change)
Actionable Insight • Neutral

Monitor the pending Court of Milan proceedings on the corporate purpose amendment and the multiple voting mechanism challenge, as outcomes could shift governance dynamics. The group's voting power remains stable at ~18.9%, but the massive share issuance (24.6M new shares) significantly diluted economic ownership.

Executive Summary

This Amendment No. 1 to Schedule 13D reports a decrease in the group's beneficial ownership percentage from 11.50% to 11.50% (unchanged) of outstanding shares, but a decrease in voting power from 18.90% to 18.94% (slight increase) due to the issuer's allotment of 24,625,838 new ordinary shares on May 29, 2026, changes in enhanced voting rights, and a separate open-market purchase of 110,000 ADSs by Fin Posillipo S.p.A. for ~$143,000. The filing also updates on pending litigation in the Court of Milan regarding the suspension of a corporate purpose amendment, with interim relief initially granted then revoked.

Risk Factors

  • Pending litigation in Italy could result in adverse rulings affecting shareholder rights or corporate governance.
  • Further dilution possible if the issuer continues to issue shares or completes additional transactions.
  • Group cohesion may be tested as Posillipo's ADS purchases were unilateral and not coordinated with other members.
