Where merger value is really made — or lost.

Why M&A integration fails

Research by McKinsey and Harvard Business Review consistently finds that 70–90% of M&A transactions fail to create the anticipated value. The financial modelling is usually sound. The strategic rationale usually holds. What breaks down is the integration of two organisations with different cultures, processes, leadership styles and ways of working.

When integration is treated as a project management exercise rather than a change management challenge, key talent leaves, cultural conflict undermines productivity, and the combined entity performs worse than either organisation did independently.

What M&A change management covers

• Cultural assessment of both organisations — before and after close
• Leadership team alignment and unified communication strategy
• Workforce integration planning — including role impacts, redundancy management and retention of key people
• Process harmonisation change management — managing the human side of combining operating models
• Customer communication and relationship continuity
• Post-merger culture design — defining what the combined entity stands for
