What investors look for when they evaluate a business

There is no mystery to how institutional investors assess private businesses. The criteria are well established, consistently applied, and largely shared across private equity firms, strategic acquirers, family offices, and credit providers. The work of evaluation is rigorous, but it is not idiosyncratic. The same questions get asked, in roughly the same order, on roughly the same evidence, by people who have done this many times before.

What is surprising is how rarely founders encounter that framework before they need it. Most see it for the first time in the middle of a sale process, by which point the structural conditions that drive valuation have already been set. The diligence questionnaire arrives. The model gets rebuilt. Discounts get applied. The founder, often for the first time, sees their business through the lens that determines what it is actually worth.

This essay sets out the criteria investors use to evaluate a private business. It is not a checklist. It is the underlying logic. Each criterion connects to a specific question the buyer is trying to answer about future cash flow, risk, and the durability of performance under new ownership. Understanding that logic well in advance is what separates a defensible valuation from a discounted one.

The point of writing it down is straightforward. Founders who understand what investors are evaluating tend to build businesses that score well against those criteria. Founders who do not, generally do not.

I · The Starting PointQuality of earnings, not headline EBITDA

The first thing a serious buyer does is verify that the earnings they are being asked to value actually exist. This is not a check for fraud. It is a check for clarity.

Founder-led businesses often carry expenses that are partly operational and partly personal. Vehicles, travel, family members on payroll, premises arrangements, discretionary bonuses, and selective capitalisation policies are all common. None of these are necessarily problematic. They simply mean that the EBITDA in the management accounts is not the same EBITDA an institutional buyer is willing to underwrite.

The work of normalising earnings is called Quality of Earnings, and it is the foundation on which every other valuation conversation rests. Buyers want to understand what the business genuinely produces under normalised conditions, with one-off items removed, owner extraction restated, and accounting policy decisions made transparent.

Founders who present credible, well-documented normalisations enter a process from a position of strength. Founders who present headline EBITDA without preparation generally see it adjusted downward by the buyer's advisers, and the valuation conversation begins from a weaker base than it needed to.

II · The Revenue TestDurability before volume

Once earnings are established, attention moves to the revenue that produced them. Institutional buyers are not particularly interested in revenue size in isolation. They are interested in revenue durability under their ownership.

The questions they are working through are practical. Where does revenue come from. How much of it repeats. What contracts sit behind it. How concentrated is it across customers, channels, or relationships. What happens if a key account leaves. What does churn behaviour look like across the existing base. How long does an average customer stay, and what do they spend over that period.

These questions resolve into a view of revenue quality. Revenue secured by multi-year contracts with low churn carries one valuation profile. Revenue generated through repeatable transactions across a diverse base carries another. Revenue produced through founder-led activity across a small number of accounts carries a third, generally less attractive, profile.

Two businesses with identical turnover can sit in materially different valuation brackets on the basis of revenue quality alone. The buyer is not trying to be unfair. They are trying to estimate what survives the transition.

III · The Margin QuestionDefensibility and pricing power

Margin is one of the most informative numbers in a business. It tells the buyer something the founder may not always articulate clearly themselves, which is how much pricing power the business actually has in its market.

Strong gross margins, sustained over time, generally indicate a differentiated position. The customer is paying for something they cannot easily replicate, replace, or commoditise. Margins that have improved as the business scaled suggest operating leverage and disciplined cost behaviour. Margins that have compressed under growth, or that fluctuate materially across years, suggest something less stable.

Buyers also examine how margins behave under stress. What happens during periods of input cost inflation, customer pressure, or competitive entry. Businesses that pass costs through to customers without losing volume sit in a different valuation bracket from businesses that absorb cost pressure into margin.

The underlying question is simple. Does the business set its price, or does the market set its price for it. The answer materially affects what the future cash flows look like, and therefore what the business is worth today.

IV · The Growth QuestionAn underwriteable forward case

Every founder describes a growth story. The buyer's job is to determine which parts of that story can be underwritten.

An underwriteable growth case is one a buyer can defend internally to an investment committee, with evidence the committee will accept. That generally means growth supported by signed contracts, pipeline of credible quality, demonstrated capacity to deliver, and a market large enough to absorb the projected expansion without strain.

The distinction matters because it determines how the forward case is treated in the model. Underwriteable growth is reflected in the headline valuation. Aspirational growth tends to be discounted, contingent, or moved into earn-out structures that transfer execution risk back to the seller.

Founders sometimes underestimate how much of their valuation depends on whether the growth thesis holds together. The headline number a buyer prints is rarely a comment on the past. It is a position on the future. Anything the founder can do to make that future more defensible, more documented, and more transferable improves the price.

V · The Leverage TestHow additional revenue becomes profit

One of the most attractive characteristics in a private business is operating leverage. The ability to add revenue without adding proportional cost. The clearest signal of an institutionally investable business.

Buyers test this carefully. They look at how cost has scaled relative to revenue over the past three to five years. They examine the contribution margin on incremental revenue. They check whether overheads have grown faster, slower, or in line with the top line. They model what happens to profit if revenue grew by twenty per cent next year, by forty per cent, by fifty per cent.

Businesses with genuine operating leverage produce a particular pattern. Revenue rises. Variable costs follow proportionally. Fixed costs grow modestly. Profit margin expands materially. The next pound of revenue is more profitable than the last.

Businesses without operating leverage produce a different pattern. Revenue rises, costs rise alongside it, and profit margin holds or compresses. Growth continues, but it does not translate into improved economics. This pattern is generally valued less generously because future growth, even if achievable, does not compound enterprise value the way leveraged growth does.

VI · The People TestWhat survives the founder departing

Of all the criteria investors evaluate, leadership depth is the one most consistently underweighted by founders themselves. The reason is straightforward. The founder is generally inside the business every day, holding the standard, resolving ambiguity, and making most of the decisions that matter. From the inside, the team appears strong because the founder is filling the gaps in real time.

Buyers cannot see the team that way. They see what is documented, what is delegated, and what is institutionally repeatable. They ask which decisions get made without the founder. They examine who owns the major customer relationships, the operational systems, the commercial pipeline, and the financial reporting. They look for evidence that performance has been generated by an organisation, not by an individual.

The depth of management beneath the founder is the single largest determinant of how much the founder is paid at completion versus how much sits in earn-out or retention structures. Strong leadership depth means a buyer can underwrite the business as an asset. Limited leadership depth means the buyer is partly underwriting the founder themselves, which produces a very different deal structure.

This is rarely about the founder's individual capability. It is about whether the institution behind the founder has been built deliberately enough to operate without them.

VII · The Position TestWhere the business sits in its market

Market position is the criterion buyers spend the most time investigating and founders spend the least time articulating. It is also one of the most influential drivers of valuation in the lower mid-market.

The question the buyer is trying to answer is structural. Is this business a participant in its market, or is it a leader within a defined niche of it. Does the business have a defensible position that produces pricing power and customer preference, or does it compete primarily on relationship, responsiveness, and price.

Defensible position can take many forms. Specialisation in a niche too small for larger competitors to enter efficiently. Switching costs that make customers reluctant to leave. Reputation in a specific sector or geography that compounds over time. Operational capability that competitors cannot easily replicate. Regulatory or certification advantages that limit who else can credibly participate.

What buyers want to see is not market share for its own sake. It is structural advantage. The clearer the answer to the question "why does this business win", the stronger the valuation conversation tends to become.

VIII · The Cash TestWhat actually reaches the bottom of the page

Profit and cash are not the same thing. Buyers know this. Founders sometimes forget it.

The work of cash conversion sits at the back end of every diligence process and quietly affects the headline valuation. Buyers examine how reliably reported profit translates into distributable cash, what working capital cycle the business operates on, how capital expenditure has behaved historically, and whether maintenance investment has been deferred in ways that will need to be made up under new ownership.

Businesses with strong cash conversion produce a particular signature. Profit translates into cash with limited friction. Working capital does not absorb growth disproportionately. Capital expenditure runs at a stable, predictable level. The buyer can model returns on the basis of what the business actually generates, rather than on the basis of an accounting figure that requires significant reconciliation.

Businesses with weaker cash conversion tend to attract more conditional valuations, longer earn-out structures, and tighter working capital adjustments at completion. None of these are inherently unfair. They are mechanisms buyers use to manage the gap between accounting profit and underlying cash.

IX · The ScorecardHow investors weight what they evaluate

The criteria above are not assessed equally. Different buyers, different sectors, and different transaction types weight them differently. A trade buyer focused on synergies will weight strategic fit and customer overlap more heavily than a financial sponsor focused on standalone returns. A credit provider will weight cash conversion and resilience above growth. A founder considering a partial exit to a growth investor will see growth thesis and leadership depth dominate the conversation.

That said, a representative weighting for a typical lower mid-market private equity evaluation looks roughly as follows. It is illustrative rather than definitive, but it gives founders a useful sense of where attention concentrates.

The notable observation is how heavily the early criteria weight. Quality of earnings, revenue durability, and leadership depth together generally account for more than half of the evaluation. These are also the criteria that respond most slowly to short-term effort. They cannot be repaired meaningfully in the weeks before a process. They are built over years, intentionally, by founders who understood the framework while they were still able to act on it.

X · The Diligence RealityWhat buyers actually find

Diligence is where the gap between how a business presents and how a business actually performs becomes visible. It is rarely catastrophic. More commonly, it produces a series of small revisions that, taken together, materially change the deal.

Reported EBITDA gets normalised. Recurring revenue gets reclassified after the contracts are read. Top-customer concentration gets recalculated on a more granular basis. Working capital baselines get reset. Growth projections get tested against historical pipeline conversion. Leadership succession gets stress-tested through interviews. Operating systems get examined for documentation and repeatability.

Each of these findings, on its own, is generally manageable. Collectively, they produce two outcomes for the seller. Either the headline price moves downward, or the structure shifts toward earn-outs, deferred consideration, and retention mechanisms that transfer risk from buyer to seller.

Founders who experience this for the first time during a live process generally describe it as a difficult phase. Founders who have anticipated it, prepared the answers in advance, and pressure-tested their own business against the same lens generally experience diligence as a confirmation rather than a surprise. The valuation outcomes diverge accordingly.

XI · The Preparation WindowWhy twelve to thirty-six months matters

The criteria investors use are not difficult to understand. They are difficult to influence quickly. That is the central insight founders need to internalise.

Quality of earnings can be tightened in twelve months. Revenue durability typically takes eighteen to thirty-six. Leadership depth requires hiring, integrating, and proving the second layer of management, which rarely takes less than two years. Market position is generally a multi-year exercise. Cash conversion can be addressed faster, but the underlying cycle of the business takes a full year to restate cleanly.

The window of effective preparation is therefore not measured in weeks or months. It is measured in years. Founders who begin preparing twelve to thirty-six months before they intend to transact materially out-perform founders who decide to sell, engage advisers, and discover the evaluation framework simultaneously.

The work is not exotic. It involves identifying which criteria most heavily affect the valuation of the specific business in question, addressing the gaps that are still addressable, and presenting evidence in a form institutional buyers recognise. None of this requires a different business. It requires the existing business to be presented through the lens that will actually be used to evaluate it.

XII · The ProcessWealth & Business Design

The Wealth & Business Design process exists to bring the investor evaluation framework forward in time, so founders can act on it while it is still possible to influence the outcome.

The process assesses the business against the same criteria a credible institutional buyer would apply, produces a defensible view of indicative value today, and identifies the specific structural improvements that would shift that value most materially over the next twelve to thirty-six months. It is intended to provide founders with the same lens, the same vocabulary, and the same evidence base that buyers themselves use, well in advance of any transaction conversation.

The objective is straightforward. To narrow the gap between how the business is experienced internally and how it is evaluated externally. And to do so while the time required to act on that gap is still available.

XIII · A Closing ObservationThe cost of meeting the framework too late

Every founder eventually encounters the investor evaluation framework. The question is whether they encounter it when they can still act on it, or after the structural conditions have already set.

The businesses that achieve premium valuations are rarely distinguished by extraordinary performance. They are distinguished by having been designed, over years, to score well against criteria the founder understood in advance. That is not luck. It is preparation, applied consistently over a long enough horizon to produce a structurally different asset by the time a buyer arrives.

Founders who reach a process unprepared rarely lose the deal. They lose the multiple. The difference, on a typical lower mid-market transaction, can comfortably represent several years of post-tax personal income to the founder. It is the most expensive lesson in private enterprise, and it is also one of the most avoidable.

The framework is published. The criteria are known. The window to act on them closes more quickly than founders generally expect.
