Leadership-Driven Value Creation in Cross-Border Mergers and Acquisitions: Event Study Evidence from Microsoft

Abstract

This study examines how leadership influences value creation in cross-border mergers and acquisitions by analysing capital market reactions to Microsoft’s international acquisition announcements. Positioned at the intersection of finance, international business, and leadership studies, the paper investigates whether leadership-driven strategic coherence shapes investor perceptions of cross-border M&A outcomes. Using an event study methodology, the research evaluates abnormal and cumulative abnormal returns surrounding Microsoft’s cross-border M&A announcements under Satya Nadella’s leadership, drawing on established event study techniques to capture short-term market responses. The analysis reveals that Microsoft’s cross-border acquisition announcements are generally associated with positive and statistically significant abnormal returns, indicating that investors perceive these transactions as value-enhancing. The findings suggest that leadership credibility, organisational learning, and strategic clarity play a critical role in mitigating the uncertainty typically associated with cross-border acquisitions. Rather than viewing international M&As as inherently risky, the market appears to interpret Microsoft’s acquisitions as integral components of a coherent long-term strategy focused on innovation, global integration, and platform-based growth. This study contributes to the literature by demonstrating that leadership functions as a key mediating mechanism between cross-border M&A strategy and shareholder value. The results highlight the importance of leadership-driven governance and strategic alignment in shaping market expectations. Future research may extend this framework across firms and industries, and examine the long-term performance implications of leadership-led cross-border acquisitions.
