M&A in 2026 is a graveyard of good intentions. KPMG benchmarks confirm that 83% of deals fall short of their synergy targets. Why? Because executives prioritize the deal over the delivery. Post-merger paralysis is the silent killer of shareholder value.

The Synergy Gap

Only 30% of deals meet their internal financial targets according to Bain 2025/2026 data. The gap between the pitch deck and the balance sheet is widening. If your integration plan is not audited with the same rigour as your due diligence, failure is a mathematical certainty.
