M&A Failure: Why 83% of Synergies Never Materialise
The execution gap in M&A is destructive. Learn why 83% of mergers fail to deliver and how to avoid post-merger paralysis.
The M&A market in 2026 is unforgiving. Despite record deal volumes, KPMG benchmarks remain dismal: 83% of mergers fail to deliver the promised synergies. The reason is rarely the deal math; it is the execution gap.
Most CEOs buy the P&L but inherit a nightmare of cultural friction and technical debt. Integration is not a side project for your existing leadership; it is a full-time surgical operation. When you merge two entities without a unified operating model, you create a 'frankenfirm' that is less efficient than its individual parts.
ROI in M&A is found in the first 100 days. If you haven't harmonised your data architecture and governance frameworks within this window, you have already lost. The BCG data is clear: deals that prioritise cultural cohesion and rapid operational integration outperformed their peers by 43% in share price.
Deal-making is ego; integration is excellence. Choose the latter.
