Post-Merger Paralysis: The £134bn Cost of Failed PMI Integration

83% of UK M&A deals fail to deliver their promised synergies. The culprit is not the deal itself, but the paralysis of post-merger integration.

The board signs the deal, the champagne is poured, and then the value evaporates. Why? Because most executives treat integration as an afterthought. Post-Merger Paralysis (PMP) costs the UK economy £134bn annually in eroded value.

Synergy is not a buzzword; it is a measurable output of operational alignment. If your systems do not talk to each other within 90 days, your deal is failing. We provide the Lead Auditor rigour to ensure that day-one readiness actually means day-one value.

Do not be part of the 83% failure statistic. Execute with precision.
