Rebuilding Post-Merger Integration to Protect Deal Value
An acquirer whose prior transaction closed successfully but fell short of its projected synergy value.
We started integration planning before signing, and the acquirer met its first-year synergy target, which it had not done on its previous deal.
Situation
Accountability for a synergy case is strongest while the deal is being negotiated and weakest the moment it is signed. That is exactly when execution needs an owner. The 100-day plan, with a named lead for each workstream from Day 1, is standard M&A practice for closing that gap.
The acquirer's last transaction had followed the usual sequence of close first, plan later. Two key people left within a quarter, the acquired company's systems stayed separate, and the projected synergies did not arrive.
What we did
For the new transaction we reversed the sequence and began integration planning before the deal closed.
| Issue on the prior deal | What we did this time |
|---|---|
| Two key people left in the first quarter | Retention agreements signed before the deal was announced internally |
| Nobody owned synergy delivery after close | A named owner for every workstream under a 100-day plan |
| Systems never integrated | Systems integration scoped and budgeted as part of the deal |
Impact
- Twelve months after close, every person identified as key was still with the business.
- The synergy figure the business case set for year one was delivered. On the previous transaction it had been missed.
- The approach is now written down as a playbook that the acquirer applies to later deals.
What made it work
Systems integration was approved and funded with the transaction. It did not have to compete for money afterwards, which is where it had stalled before.
Timing the retention agreements ahead of the announcement also mattered. The people the deal depended on had an offer in hand before uncertainty set in.

Why Most Acquisitions Fail to Deliver Promised Synergies
The deal team owns the synergy number until signing. After that, in many acquisitions, nobody does.
Due Diligence Beyond the Data Room
A data room contains what the seller chose to show. The risks that move price usually sit outside it.
