Court of Milan Denies Application for Interim Suspension of ATC Capital Increase

By order dated October 2, 2026, and notified to Genenta Science S.p.A. (the “Company”) on October 5, 2026, the Court of Milan (the “Court”) denied in full the application for interim relief brought by certain minority shareholders of the Company challenging the capital increase approved by the Company’s Board of Directors on May 18, 2026, in connection with the Company’s acquisition of A.T.C. S.r.l. (“ATC”). As a result, the capital increase, including the issuance of shares in connection with the ATC acquisition, has not been suspended and remains effective pending proceedings on the merits, and subject to any appeal relating to the Court’s order.

The ATC acquisition and related capital increase were previously disclosed in the Company’s Report on Form 6-K furnished to the U.S. Securities and Exchange Commission (“SEC”) on May 29, 2026. At this preliminary stage, the Court concluded that the plaintiffs did not establish unequivocal elements of unlawfulness in the conduct of the Company’s Board of Directors sufficient to warrant the requested interim suspension of the capital increase, or the subsequent resolution adopted at the shareholders’ meeting held on June 29, 2026 appointing the Company’s Board of Directors.

The Court’s order relates solely to the interim relief sought by the plaintiffs. The underlying civil action on the merits remains pending, and the order does not constitute a final determination regarding the validity of the challenged resolution or the plaintiffs’ underlying claims.

The Company intends to continue to defend the proceedings and believes that its actions were taken in the best interests of the Company and its shareholders.
