## Summary
Synergies are usually boardroom fiction. Without a brutal PMO, your acquisition is just an expensive mistake.

## Full Content
M&A is an ego game that shareholders usually lose. KPMG benchmarks for 2025/2026 show an 83% synergy shortfall. Most CEOs buy growth because they cannot build it. Then they fail to integrate.

Only 30% of strategic acquisitions meet their original targets. 60% of deals trail the share price after 12 months. This is not bad luck. It is poor execution.

A successful merger requires a ruthless PMO. You need to strip out duplication on day one. If you wait 100 days to find synergies, they are already dead. Stop chasing the deal and start chasing the integration.
