The forward-looking statements in this Current Report represent the views of the Company and Alternus as of the date of this Current Report. Risks in addition to those set forth herein may also materialize. Moreover, the Company’s and Alternus’s assumptions may prove to be incorrect. Actual results could differ materially from the results implied or expressed by the forward-looking statements in this Current Report.

Except to the extent required by applicable law, neither the Company nor Alternus undertakes to update, supplement or amend any of the forward-looking statements in this Current Report at any time after the date hereof. You should, therefore, not rely on these forward-looking statements as representing the views of the Company or Alternus as of any date subsequent to the date of this Current Report. In addition, actual results or stockholder values may differ materially from those indicated by these forward-looking statements as a result of various important factors, including, but not limited to, our ability to raise the necessary financing required to acquire the targeted renewable energy power plants listed herein and in other documents, on suitable terms. At this time, we do not have any offer to finance these plants and there is no guarantee that such financing will be agreed on suitable terms, or at all.
