The news of a strategic partnership with a major airline group like Lufthansa could be seen as a strong validation of Lilium's eVTOL technology and market potential. This could positively influence investor sentiment and increase the stock's attractiveness in the short term. However, as the agreement is currently a non-binding Memorandum of Understanding, the long-term impact will depend on the development of the partnership and the successful implementation of the eVTOL operations.
