How boards can evaluate M&A targets more effectively

A board rarely evaluates just one acquisition. Even a company that closes a deal every couple of years is running a programme of sorts, a sequence of capital decisions that should build on each other. The board approving its fifth acquisition has four before it to learn from: what the models promised against what the businesses delivered, which integration assumptions held, where diligence missed something. The most effective evaluators bring that evidence to bear on the target in front of them. Most do not, because the learning from earlier deals sits in board packs nobody reopens. 

This matters more than it might seem, because the programme itself is where the returns are. McKinsey's analysis of the world's largest public companies has found repeatedly that programmatic acquirers outperform every other M&A strategy, including organic growth, on excess shareholder returns. What separates the programmatic acquirer from the opportunistic one is not deal volume. It is a consistent basis for evaluating each target, applied deal after deal, so that conviction compounds rather than resets. 

That consistent basis is what a board contributes. Management builds the case for a target; the board challenges and validates it against criteria that do not shift with the enthusiasm of the moment. This article sets out a framework for doing that across five dimensions, and for running the discussion that turns scrutiny into a decision. 

This piece assumes a target is already on the table. The earlier question, where the board's leverage sits across the whole deal and why the mandate matters more than the approval, is covered in our article on the board's role in M&A. Here, the focus is the evaluation itself. 

In this article: 

• A five-dimension framework for evaluating a target: strategic fit, financial case, risk profile, integration readiness, and governance and culture 
• The single question each dimension turns on, and the sub-questions beneath it 
• Why prior deals are the board's most underused evaluation tool, and how to bring them to bear 
• How to structure the board discussion so scrutiny produces a decision rather than a general sense of comfort 

A framework for board-level target evaluation 

The five dimensions below are not a scoring sheet. They are the areas where a board's challenge adds the most value, and each leads with the question it turns on. 

Strategic fit: does this target support our direction? 

The first test is whether the target advances the strategy the board has set, or whether it is an attractive business that happens to be available. The distinction blurs easily when a target looks strong on its own terms, and it is the most common way a programme drifts. 

The questions beneath it: 

• Which specific part of our strategy does this target advance, and is it the part we said mattered most? 
• Does this fit the pattern of what we have been building, or does it pull us into something adjacent that we would not have chosen to enter deliberately? 
• If we had never been shown this target, would we have gone looking for something like it? 

That last question is where prior deals earn their place: a board that sees its previous acquisitions clearly will know when a new target fits the thesis and when it is a rationalisation after the fact. This is also where human judgement does work no model does. As Sunil Thakur, Partner at Quadria Capital, puts it in Datasite's 2026 research with FT Longitude, “The house itself may be dilapidated and may even look terrible on paper, but it still gives you the right feeling”. Strategic fit is often a judgement that overrides or qualifies what the numbers say, in both directions. 

Financial case: are the assumptions realistic? 

A board cannot and should not re-run management's model. Its contribution is to test the assumptions the model rests on, because that is where optimism hides and where independence matters most. 

The questions beneath it: 

• What has to be true for this valuation to work, and which of those assumptions is the deal team least certain about? 
• How do the synergy estimates compare with what our last few acquisitions actually delivered, as opposed to what they promised at approval? 
• What is the downside case, and can we live with it if the base case does not materialise? 

The second question is the programme-level one, and it is routinely skipped. A board that has approved several deals holds a record of forecast versus outcome that bears directly on the credibility of the next projections. If the last three deals delivered 60% of the synergies claimed, that is the most useful single input into evaluating the fourth, and it usually sits unexamined in old board papers. 

The financial case is also increasingly built with AI, which sharpens rather than removes the board's job. Datasite's research found that 66% of dealmakers believe using AI across the deal lifecycle is a crucial way to de-risk deals, and AI now takes the lead in identifying targets and drawing up shortlists for a substantial share of them. That makes the analysis faster and broader. It does not make the assumptions true, and a model produced quickly is not a model the board has understood. The board's questions matter more as the analysis gets more automated, not less. 

Risk profile: what could go wrong, and how seriously? 

Every acquisition carries risk. The board's task is to separate the risks that are priced in and tolerable from the ones that could unravel the deal, and to make sure the second category has been examined rather than assumed away. 

The questions beneath it: 

• What is the one risk that, if it materialised, would make this deal a mistake, and how likely is it? 
• Which risks are we accepting because they are genuinely tolerable, and which because addressing them would slow the deal down? 
• Where has diligence gone deep, and where has it relied on the seller's own representations? 

Security and cyber risk deserve specific attention, because they are now a standard line in every diligence report and routinely taken at face value. A clean report is not a clean target. The board, or a director with the expertise, should press on the methodology: how deeply were the target's security fundamentals examined, what level of cyber maturity has been assumed, and does that assumption match reality? Where it does not, the cost of closing the gap is a real number that belongs in the financial case, not a footnote. Where the board lacks the expertise to ask, the CISO should review the diligence itself, an hour of time that regularly changes the picture.  

Integration readiness: can we execute this well? 

Most acquisitions that fail do so in integration, not selection. The target may be sound and the price fair, and the deal still destroys value because the organisation could not absorb it. This is the dimension boards most often underweight, because it concerns the acquirer's own capacity rather than the target's merits. 

The questions beneath it: 

1. Do we have the integration capacity to execute this now, given everything else already in flight? 
2. Who owns the integration, and are the synergies in the model tied to named people with dates? 
3. What did we learn from integrating our last acquisition, and has that been built into this plan? 

Capacity is one of the three defining habits of successful serial acquirers that McKinsey identifies, alongside competitive advantage and conviction. And there is a specific programme-level trap here: research on serial acquirers finds that returns tend to fall when deals are done in quick succession, in blocks, because integration capacity gets overstretched. A board evaluating a target in isolation cannot see that risk. A board evaluating it as the third deal in eighteen months can. 

Governance and culture: are there red flags? 

The softest dimension is often the one that decides whether a deal works, and the hardest to put in a model. Governance and cultural misalignment rarely stop a deal at approval, and frequently undermine it afterwards. 

The questions beneath it: 

• What does the target's own governance and decision-making culture tell us about how it will behave once it is ours? 
• Are there related-party arrangements, key-person dependencies, or founder dynamics that the financial case does not capture? 
• Where are our culture and the target's most likely to collide, and what happens to the thesis if they do? 

A board that has integrated several businesses knows what cultural warning signs look like from experience, which is one more reason the programme's own history is the board's sharpest evaluation instrument. 

How to structure M&A discussions in board meetings 

A rigorous framework produces nothing if the meeting is run badly. The evaluation discussion is where it either works or collapses into a presentation the board nods through. 

Share the materials early enough to be read. Target evaluation materials, the model, the diligence findings, the risk assessment, should reach directors at least a week before the meeting. Directors should form their assessment of each dimension before the meeting, not during it. A board seeing the numbers for the first time in the room is being briefed, not consulted, and cannot challenge what it has not had time to examine. 

Open with the question, not the presentation. The Chair should frame the discussion around a single explicit question: does this target meet the strategic and financial criteria we have set? That anchors every contribution to the decision at hand rather than to whichever feature of the deal is most salient. 

Structure the challenge. Evaluation benefits from directors presenting alternative views before the Chair synthesises. A discussion where the first confident opinion sets the frame is not a challenge, and the dimensions most likely to be waved through, integration and culture, are exactly the ones that need a dissenting voice. 

Verify the position on each dimension before recording it. Before a decision is minuted, the board's conclusion on each of the five dimensions should be confirmed and captured, along with the conditions attached. That record is what the board reviews the deal against later, and what informs the evaluation of the next target. 

The test of a good evaluation process 

Ask whether the board could state, after the discussion, its explicit position on each of the five dimensions rather than a general sense that the deal looked reasonable. Ask whether anyone in the room brought the actual performance of the last acquisition into the assessment of this one. Ask whether the integration and culture dimensions received as much challenge as the valuation. If the answers are no, the board is approving deals rather than evaluating them, however thorough the papers looked. 

How Sherpany supports board-level M&A evaluation 

Evaluating a target well depends on two things a board often lacks in the moment: the ability to interrogate dense material quickly, and the ability to see this deal in the context of every deal before it. 

Sherpany consolidates target evaluation materials, from diligence reports to financial models and management proposals, in one secure place with access scoped to authorised directors rather than the board as a block. Where a director needs to test a claim in a lengthy report or a complex model, Document Copilot lets them question the document directly in natural language rather than reading it page by page, turning a week of reading into targeted scrutiny. Evaluation topics can be structured and prioritised before they reach the agenda, so the board spends its meeting deciding rather than orienting, and where a formal position is required, the vote is recorded alongside the material it relates to. 

The programme-level benefit is the one that compounds. When each evaluation, its conclusions on all five dimensions and the conditions attached, is captured as a decision rather than lost to the minutes, the board approving its fifth acquisition can actually see the first four: what was assumed, what was delivered, what the diligence missed. The thesis gets stronger as evidence accumulates instead of resetting with each deal. Board composition and M&A oversight are two of the three areas examined in Sherpany's guide to strategic decision-making at mid-year. 

Evaluation is a programme discipline, not a single decision 

The board that evaluates targets well is not necessarily the one with the sharpest questions on the day. It is the one whose questions are the same across every deal, informed each time by what the last one taught it: strategic fit tested against a stable thesis, financial assumptions checked against real prior outcomes, integration capacity assessed honestly, and cultural risk given the weight it deserves. 

Done once, that is diligence. Done consistently, deal after deal, with each evaluation informing the next, it is what separates the acquirers who compound value from the ones who keep starting over. The framework is the same every time. What improves is the evidence the board brings to it.
