Other Events

Extraordinary Shareholders’ Meeting

On July 29, 2026, Genenta Science S.p.A. (the “Company”) held an Extraordinary Shareholders’ Meeting in virtual meeting format.

At the meeting, the proposal to amend Article 1 of the Company’s by-laws to change the Company’s corporate name from Genenta Science S.p.A. to Saentra Forge S.p.A. was not put to a vote. At the request of the Company’s shareholders, consideration of the proposal was deferred in order to allow for the completion of ongoing evaluations relating to the Company’s communication, branding, and corporate identity strategy and to provide additional time for shareholder consultations. The proposal will be considered at a reconvened Extraordinary Shareholders’ Meeting scheduled for September 10, 2026, at 5:00 p.m. CET, on first call, and, if necessary, September 11, 2026, at 5:00 p.m. CET, on second call.

The Company’s shareholders approved the remaining proposals on the agenda by a substantial majority, as detailed below.

Delegation to the Board to Increase Share Capital and Issue Convertible Bonds

The Company’s shareholders approved the proposal to grant the Board of Directors of the Company (the “Board”), pursuant to Articles 2443 and 2420-ter of the Italian Civil Code, authority for a period of five years to:

The authorization provides the Board with flexibility to determine the terms, timing and structure of future issuances consistent with applicable law and the resolutions adopted by the Company’s shareholders, including in connection with strategic transactions, capital raises, equity incentive plans and other corporate purposes.

Reverse Stock Split Authorization

The Company’s shareholders also approved a reverse stock split of the Company’s ordinary shares at a ratio within a range of no. 1 new ordinary share for every no. 10 to no. 20 existing ordinary shares, together with the related amendments to Article 6 of the Company’s by-laws.

The Board has been authorized to determine, in accordance with the parameters set by the Shareholders’ Meeting resolution and within 12 months from the date of the Shareholders’ Meeting, whether to effectuate the reverse split, and if so, the specific ratio within the range approved, the effective date, and implementation of the reverse stock split, including coordinating with Euronext Securities Milan S.p.A., The Bank of New York, as depositary of the Company’s American Depositary Shares, and other applicable authorities. The reverse stock split is intended to assist the Company in maintaining compliance with Nasdaq’s minimum bid price requirement.

If the Board decides to proceed with the reverse split, the Company will announce the effective date of the reverse stock split once determined by the Board.
