This study explores the challenges and complexities of cross-national mergers and acquisitions. The study made use of qualitative data that was gathered from employees of companies that have recently undergone M&A in the UAE and the UK in 2024. The findings have shown that the key motivations for M&A are diversification, market consolidation, and expansion. However, with these benefits, M&A brings the challenges of cultural misalignment, integration failures, loss of trust of stakeholders, and overvaluation of the targeted companies. Moreover, the study has also found that the negative effects are more prominent in the hospitality sector, where there are more chances of employee resistance, reduced customer loyalty, increased operational costs, and communication breakdowns. Finally, the study has recommended strategies like conducting thorough due diligence, increasing two-way communication, and fostering a strong organizational culture. To recapitulate, M&A does offer opportunities for growth and success but these come with risks and challenges.
