Abstract
Mergers and acquisitions (M&As) continue to be prevalent despite frequently yielding disappointing outcomes. Postmerger integration plays a critical role in M&A success, yet many questions about M&A implementation remain unanswered. In this article, we review research on postmerger integration, which we organize around strategic integration, sociocultural integration, and experience and learning. We then lay out a research agenda that centers on expanding our understanding of processual dynamics in postmerger integration. We focus on opportunities related to temporality, decision-making, practices and tools, and emotionality.
