## Summary
83% of M&A deals fail to deliver their promised synergies. The reason is not the deal price; it is post-merger paralysis.

## Full Content
The logic of M&A is always synergistic, yet the reality is often catastrophic. 83% of UK deals fail to meet their stated objectives. The value is lost in the first 100 days because of a lack of operational integration.

Integration is not a "soft" skill. It is a rigorous audit of culture, technology, and process. Most firms focus on the transaction and ignore the transition. This results in post-merger paralysis where talent exits and customers follow.

We specialize in the hard reality of post-deal execution. We do not do "synergy workshops". We do commercial alignment. If your M&A strategy is not delivering a clear ROI within the first year, it is a failed investment. Stop talking about "fit" and start talking about "function".
