Post Merger Integration Consulting
Post M&A integration turns deal theses into results. We align workstreams, capture synergies, and stabilize Day 1 so targets on cost, growth, and risk are met fast across finance, IT, customers, people, and supply chain.
What Is Post Merger Integration Consulting?
Advisory that converts a signed deal into one company. We build the integration management office, design the operating model, and run value capture so post merger integration success is measured and auditable. This covers post M&A integration across finance, IT, customers, talent, and post merger supply chain integration.
Why It Matters and How It Works
Many deals miss value. Research often cites failure rates of 70-90%, frequently due to weak integration. Top performers hit about 50% of public synergy run rate in year one and sustain focus beyond Day 100. Supply chain can represent 50-60% of synergies in consumer and industrial products, so we integrate planning, sourcing, manufacturing, and logistics early. Leading acquirers also invest in integration at scale—59% spend 6%+ of deal value on integration to raise success rates.

Results You Can Track
| Outcome | What We Track | Why It Pays Off |
|---|---|---|
| Synergy run rate | % of public target, pace by lever, evidence packs | Top performers reach about 50% of target in year one, supporting outperformance. |
| Integration investment | PMI spend vs deal value, ROI on integration | 59% spend 6%+ of deal value; higher spend is common among successful integrators. |
| Supply chain synergies | SKU and network reductions, PPV, service levels | Supply chain can be 50-60% of synergies in C&IP; prioritizing it accelerates value. |
| Customer retention | Churn, NPS, sales coverage, price realization | Execution gaps can erase ~40% of strategy value; tight governance protects revenue. |
| Procurement value | Run rate savings, compliance, contract cycle time | External spend is often the largest lever; procurement is a proven driver of merger savings (analysis). |

FAQs
What defines post M&A integration success?
Hitting the synergy run rate on time with stable service and minimal churn. We make that visible with a ledger of levers, owners, evidence, and cadence.
How fast should we integrate?
Stabilize Day 1, then move quickly on no-regret synergies while sequencing heavier moves. Hitting about 50% run rate in year one is a proven marker.
How do you run post merger supply chain integration?
Start with demand and service, then align SKUs, plants, suppliers, and lanes. Lock PPV, inventory, and OTD targets into the benefits tracker and manage to weekly variance.
