Post-Merger Integration

The Biggest Value Destruction Happens After Closing.
Not Before.

60% of acquisitions miss their value creation targets. The reason is almost never the purchase price, but inadequate integration. Those who write the 100-day plan only after closing have already lost.

Structured. Battle-tested. Results-driven.

The Challenge

Why integrations fail

I've just completed an acquisition and realise we have no concrete integration plan.

I'm losing key employees after the takeover because uncertainty reigns and nobody communicates.

I see customers leaving because service quality suffers during integration.

I have a 100-day plan, but execution stalls because responsibilities are unclear.

Does this sound like your situation?

Let's clarify in a free initial consultation whether and how we can help.

Context

What post-merger integration encompasses

PMI is the systematic process of merging two organisations into a functioning unit after a transaction. It covers five core areas: governance (decision structures, reporting), operations (process harmonisation, IT migration), people (cultural integration, retention), commercial (customer transition, cross-selling) and finance (consolidation, working capital). The critical phase is the first 100 days after closing.
In regulated industries, concession transfers, licence re-registrations and supervisory reporting obligations affect the integration roadmap.
Our Approach

Our PMI approach

01

Pre-closing planning

Integration planning begins before closing: governance model, communication plan, identify quick wins.

02

Day One readiness

Preparing Day One: who reports to whom, first communication to employees and customers, implement quick wins.

03

100-day plan

Structured roadmap for the critical phase: milestones, responsibilities, escalation paths, KPI tracking.

04

Stabilisation

Integration monitoring, deepen cultural integration, realise synergies, corrections where deviations occur.

What happens if you do nothing?

What happens without structured integration?

  • Customer loss: 15-25% customer churn in the first 12 months is typical for unstructured integrations.
  • Key person loss: Top performers leave the company when uncertainty reigns and no perspective is communicated.
  • Synergy loss: Without a systematic plan, planned synergies remain theoretical and are never realised.
  • Cultural rupture: Missing cultural integration leads to internal conflicts that impair productivity and service quality.
