Most M&A transactions are announced with optimism. A meaningful percentage of them — across industry after industry — fail to deliver the value that justified the deal. The gap between the two is almost never found in the analysis. It lives in execution.
Having spent more than two decades working on transactions — from strategy and screening through diligence, structuring, negotiation, and post-close — I've watched this pattern play out repeatedly. The investment thesis is usually sound. The valuation is defensible. The synergy model looks reasonable at the time of signing. What goes wrong tends to happen afterward: unclear ownership of integration decisions, talent departures that weren't anticipated, cultural friction that wasn't surfaced in diligence, and a governance structure that was designed to close the deal rather than run the business.
The Signing-Day Fallacy
There is a natural organizational tendency to treat the close of a deal as the finish line. The announcement generates internal celebration. The deal team disbands or moves to the next transaction. Leadership attention shifts. But for the business that was acquired — and for the shareholders who funded the premium — signing day is not the end of anything. It is the beginning of the hard part.
The value in most acquisitions is not locked in the purchase price. It lives in what happens next: how quickly you integrate systems, whether you retain the talent you paid for, how effectively you unlock the revenue synergies you modeled, and whether the governance structures you put in place are capable of making decisions at the pace the business requires. These are operational and leadership questions. And they require the same rigor — often more — than the transaction itself.

What Good Integration Governance Looks Like
In practice, the organizations that consistently capture deal value share a few structural characteristics. First, they separate the integration management office from the deal team — recognizing that the skills required to close a transaction are not identical to the skills required to run one. Second, they establish clear accountabilities early: who owns each synergy, with what timeline, and what does success look like at 90 days, 180 days, and one year. Third, they build a rhythm of honest performance tracking — not just reporting against plan, but identifying where the thesis is under stress and making decisions accordingly.
The third point is the hardest one. Post-close integration reporting has a tendency to become narrative rather than analytical — a story told to reassure leadership rather than a tool for course correction. The most useful integration governance I have seen is built around uncomfortable questions: Which synergies are tracking behind plan, and why? What would we do differently if we were making this acquisition decision today? Where is cultural integration stalling, and who owns fixing it? These questions require psychological safety to ask honestly, and they require leaders who genuinely want the real answer.
The People Variable
Of all the factors that determine whether an acquisition delivers its expected value, talent retention is among the most consistently underestimated. Not the retention of all talent — that is neither achievable nor desirable — but the deliberate identification and retention of the people who carry the institutional knowledge, relationships, and capabilities that made the target worth acquiring in the first place.
This requires starting the conversation earlier than feels comfortable. In many transactions, the deal team is reluctant to have retention conversations during diligence, out of concern for confidentiality or for disrupting the target's operations. That concern is legitimate. But the cost of not having those conversations — arriving at close without a clear picture of which people are flight risks, or without retention packages in place for the ones who matter most — is typically higher. This connects to a broader question of how capital allocation decisions should account for human capital, not just financial capital, when evaluating deal returns.
Applying This to Portfolio Strategy
For organizations that do acquisitions regularly, the quality of post-close execution is not just a deal-by-deal operational question — it is a strategic capability. Companies that have a systematic approach to integration, that learn from each transaction and carry those lessons forward, develop a genuine competitive advantage in M&A markets. They can underwrite premiums that competitors cannot, because they have higher confidence in their ability to realize the value on the other side of close.
Building this capability requires investment: in integration management infrastructure, in talent with genuine post-close operating experience, and in governance structures that are honest about what is working and what is not. It also requires a cultural commitment to learning — a willingness to do thoughtful post-mortems on deals that underperformed and to let those learnings genuinely shape the next transaction. His writing on finance leadership and business transformation explores how this kind of systematic organizational learning applies across the finance function more broadly.
Conclusion
M&A is among the highest-stakes decisions an organization makes. The premium paid, the resources committed, and the strategic bets embedded in an acquisition create obligations that extend well beyond signing day. Leaders who approach the post-close phase with the same discipline, rigor, and genuine engagement they bring to the deal itself are the ones who consistently deliver on those obligations. Transactions do not create value. Execution does.
