M&A Technology Due Diligence

In most acquisitions, the commercial and financial case is examined in detail long before completion. Technology and operations are too often treated as a secondary matter — a checklist exercise to be completed once the important decisions have been made. Yet it is frequently in technology, data and operations that the value of a deal is either protected or quietly lost.

The pattern is familiar. A transaction completes on the strength of its commercial logic. Months later, the integration stalls, the systems do not fit together as assumed, the data is poorer than expected, and the cost and disruption of putting it right consume the value the deal was meant to create. None of this was hidden; it was simply not examined in time.

Diligence is about the cost of integration, not just the state of the assets

Good technology due diligence does not stop at cataloguing systems. Its real purpose is to understand what it will actually take to bring two organisations together, and what that will cost in money, time and disruption. The state of the target’s technology matters, but the harder question is how it will fit with the acquirer’s, and what stands in the way.

• How dependent is the target on systems, suppliers or individuals that will be difficult to replace or integrate?
• How good is the data the deal assumes — is it complete, accurate and usable, or will it need substantial remediation?
• What contractual or licensing constraints will surface on a change of control?
• How realistic is the integration timeline, and who will actually deliver it?
• What operational risk is carried in the period between completion and full integration?

The risks that diligence most often misses

The risks that derail integrations are rarely the ones on the asset register. They are the dependencies and assumptions that sit beneath it. A target may run on a platform that only one supplier can support. Critical knowledge may rest with a small number of people who have no reason to stay. The data underpinning the commercial case may be far less reliable than the model assumed.

These are not technical curiosities; they are value risks. They determine whether the integration is straightforward or fraught, and whether the synergies in the model are achievable or aspirational. Diligence that surfaces them allows the acquirer to price them, plan for them, or walk away. Diligence that misses them leaves them to be discovered after completion, when the options are far narrower.

The risks that derail integrations are rarely the ones on the asset register. They are the dependencies and assumptions that sit beneath it.

Plan the integration before you complete the deal

The most valuable output of technology diligence is not a report; it is a credible, costed integration plan. Acquirers who understand before completion how the two organisations will come together — and who owns that work — start the post-deal period with a sense of control. Those who defer the question begin it reacting to problems they could have anticipated.

This is particularly true for private equity and for firms making their first acquisition. The discipline of asking how value will actually be realised, operationally, before the deal closes, is what separates acquisitions that deliver from those that disappoint.

Independent judgement at the right moment

Technology and operational diligence is most useful when it is brought in early and conducted independently of the deal’s momentum. By the time a transaction is close to completion, there is considerable pressure to confirm the case rather than challenge it. Independent diligence, asking the questions that matter while there is still time to act on the answers, is one of the most cost-effective protections an acquirer can put in place.

The objective is not to obstruct deals but to protect their value — to ensure that what looks compelling on paper can be delivered in practice, and that the risks that determine success or failure are understood before they become unavoidable.
