The recent growth of Cross-Border Mergers and Acquisitions (M&As) in the international arena has been phenomenal. Several factors like worldwide phenomenon of industry consolidation & privatization and the liberalization of economies are responsible for fuelling the growth. Cross-border mergers & acquisitions have been motivated due to multiple reasons, one among them being the necessary to search for new opportunities across different geographic locations and markets in a turbulent and continuously changing environment, the other being to maximise shareholder values. While the magnitude of mergers & acquisitions is undoubtedly high in developed economies, emerging economies like India and China have witnessed an unprecedented growth in merger & acquisition activity in terms of volume and number of deals in recent years. This research investigates the impact on shareholder’s wealth of TATA Motors' cross-border acquisition of Ford's ultra-luxury brand Jaguar & Land Rover. It analyses the immediate impact after acquisition announcement and verifies whether the immediate impact is impulsive by observing the impact after a year or more of acquisition.
