Ad-Hoc announcement pursuant to Art. 53 Listing Rules:

EEII AG: Update on reverse takeover of Jubin Frères S.A.

Zug, 11 December 2025

As previously announced on 29 October 2025, EEII AG ("EEII" or "Company"), through its board of directors, approved an amended structure of the acquisition of the entire share capital of Jubin Frères S.A., a company active in the trade of all types of fuel business ("Target"), fully owned by Swiss Energy Holding SA ("SEH"), by way of a share exchange (the "Transaction").

The change in the structure of the Transaction, involving additional adjustments relating to the second tranche as an in-cash capital increase, has entailed the postponement of the Transaction compared to what was previously announced, in the interests of the due implementation of the Transaction and thus all parties involved.

The execution of the new structure and the consummation of the Transaction are expected to take place by the end of March 2026.

The consummation of the Transaction remains subject to various conditions, including the negotiation and execution of definitive and binding agreements between SEH and the Company, the confirmation of the valuation of the Target by an audit firm, the listing of the currently unlisted shares of the Company, the approval of the Transaction and the second tranche of ordinary capital increase in cash by the shareholders of EEII, the consummation of the in cash capital increase, and the completion of further legal, administrative and regulatory steps, including, among others, the approval of the listing application by SIX Exchange Regulation AG and the listing prospectus by the competent prospectus office.

EEII asks all shareholders, creditors and other stakeholders to support the contemplated Transaction. Most importantly, the Transaction would result in the Company boosting its operational activities, which are likely to create value for the shareholders compared to today's situation.
