Working with Private Equity Clients in Transaction Services

The first time you run diligence for a private equity buyer, you feel the difference within an hour. The questions come faster and land harder. Nobody wants a slow build-up to a conclusion; they want the conclusion, then the evidence. And every finding is immediately weighed against one thing: does it change the price we pay, or the risk we carry? A large share of Transaction Services work is done for private equity, and PE clients are a genuinely different animal from corporate acquirers. Understand how a PE buyer actually thinks and your diligence becomes more useful, your reports land harder, and your interviews go a great deal more smoothly. This article unpacks what makes PE clients distinctive and how it reshapes the analyst's job.

Why a PE buyer reads FDD differently

A corporate acquirer usually buys for strategic reasons — synergies, market access, a product line. It often holds indefinitely and integrates the target into an existing group. A PE house is buying a financial asset it intends to sell in three to five years at a profit, frequently with significant debt layered into the structure.

That single fact changes everything about how they consume financial due diligence. A corporate may tolerate a wobble in one year if the strategic logic holds. A PE buyer cannot: their model depends on a defensible entry EBITDA, predictable cash generation to service debt, and a clear path to a higher exit multiple. They read your report hunting for anything that threatens those three pillars.

A PE buyer lives and dies by three numbers: the entry EBITDA the multiple is applied to, the cash the business throws off to service the debt, and the exit multiple they can plausibly reach. Every workstream you run should speak to at least one of them.

Speed and the investment thesis

PE processes are fast — often a competitive auction with a hard deadline. The diligence team is expected to mobilise quickly, work to a tight scope and deliver findings that map directly onto the buyer's investment thesis.

The thesis is the deal's reason for existing: we believe this business can expand margins by X, or roll up smaller competitors, or move into an adjacent market. Good TS work pressure-tests that thesis with numbers. If the thesis rests on margin expansion, the client wants you to interrogate the cost base and the historical margin walk. If it rests on growth, they want revenue quality and customer concentration laid bare. Diligence that ignores the thesis — however technically clean — is diligence that misses the point. The best analysts read the thesis first and let it shape where they dig.

The obsession with cash and downside

Two themes dominate PE diligence:

• Cash conversion. Because the structure carries debt, the business must convert profit into cash reliably to meet interest and amortisation. A PE client scrutinises the bridge from EBITDA to cash, the seasonality of working capital, and any one-off cash items propping up a period.
• Downside protection. PE buyers think in terms of "what could go wrong, and how much would it cost me?" They want the debt-like items, the contingent exposures and the fragile assumptions surfaced explicitly, not buried in an appendix.

This is why a PE-grade QoE goes beyond a tidy normalised EBITDA. It separates the sustainable, recurring earnings from the noise, flags every EBITDA adjustment the seller is leaning on, and tells the client how much faith to place in the run-rate. The buyer is paying a multiple of that number, so its reliability is the whole game. A single soft adjustment left unchallenged, multiplied by an entry multiple, can move the price by many times its face value.

A worked example: how one adjustment moves the price

Consider a target presenting an adjusted EBITDA of £10.0m, on which the buyer is bidding an 8x multiple — an enterprise value of £80m. Among the seller's add-backs is a £0.6m "one-off" cost that, on inspection, recurs every year. Watch what happens when your diligence challenges it.

One £0.6m adjustment, multiplied by 8x, is nearly £5m of value. That is the leverage a PE client is paying you to find — and why they read the QoE line by line rather than skimming the summary.

What PE wants from the net debt and NWC pack

Two analyses sit at the centre of the price mechanism, and PE clients care about them disproportionately because they feed directly into what actually changes hands at completion.

Net debt. The net debt definition determines the equity cheque. PE buyers want every debt-like item identified and argued — deferred consideration, pension shortfalls, unpaid capex, factoring, negative cash balances — because each pound of net debt is a pound off the price. Expect them to push hard on the grey-area items and to want a defensible rationale for each.

Normalised working capital. The working capital target is one of the most negotiated numbers in the deal. A target set too low hands the buyer a windfall; too high, and the buyer overpays at completion. PE clients lean on TS to build a defensible normalised level and to explain the seasonality, so they can argue the peg from a position of evidence rather than assertion.

The SPA mechanics they care about

PE buyers are deal mechanics. They know diligence findings only protect them if they translate into the Sale and Purchase Agreement, so they expect TS to think about consequences, not just observations. The touchpoints are covered in deal structure and the SPA, but the headline choice is the completion mechanism.

• Completion accounts. Price is trued up after closing based on actual net debt and working capital at the completion date. This rewards thorough diligence: every debt-like item you identify can flow into the adjustment.
• Locked box. Price is fixed at an earlier balance-sheet date, with the buyer protected from leakage between then and completion.

The locked box vs. completion accounts decision shapes exactly what your diligence must nail down, and when. Under a locked box the buyer commits to a number at the locked-box date, so the quality of your balance-sheet diligence at that date is paramount — there is no true-up to catch a miss. PE clients will want you alive to which mechanism is in play and what it demands of the analysis.

How this shapes the analyst's job

Working for PE makes you sharper. You learn to:

• Lead with the answer. PE partners have no patience for a slow build-up. State the finding, then support it.
• Quantify everything. "There's a risk" is useless; "this exposes the buyer to roughly £X" is gold.
• Tie analysis to price. Always ask: does this change net debt, the working capital peg, or the EBITDA the multiple is applied to?
• Move fast without dropping rigour. Tight timelines are not an excuse for loose work — and a PE client will remember which it was.

The data room becomes your world. You learn to triage requests, chase gaps relentlessly and reconcile inconsistent files under deadline — exactly the discipline a PE client values. That blend of speed and precision is why PE diligence is such a fast school; it forces habits that stay with you for the rest of your career. For where this sits relative to the buy-side itself, the comparison with investment banking is worth a read.

Common mistakes and red flags

• Burying the headline. A finding a PE partner has to dig for is a finding they may miss. Lead with it, quantify it, then evidence it.
• Analysis with no price consequence. If you cannot connect a piece of work to EBITDA, net debt or the working capital peg, ask whether it belongs in the report at all.
• Waving through the seller's add-backs. Every EBITDA adjustment the seller presents is one you are paid to challenge. Accepting them at face value is the cardinal sin — as the worked example shows, the cost compounds through the multiple.
• Ignoring the SPA mechanism. Diligencing as if it were completion accounts when the deal is a locked box (or vice versa) means you test the wrong things at the wrong date.
• Confusing speed with corner-cutting. PE timelines are tight, but a rushed net debt schedule that misses a debt-like item costs the client real money.

In the interview

Interviewers love to test whether you understand the buyer behind the report. Expect: "How does diligence for a PE buyer differ from a corporate?"

A strong answer sounds like this:

"A corporate is usually buying for strategic fit and may hold forever, so it can look past a soft year. A PE buyer is buying a financial asset to sell on, often with leverage, so it lives and dies by three things: a defensible entry EBITDA, reliable cash conversion to service the debt, and a clear path to a higher exit. That means my diligence has to be ruthless about the sustainability of earnings — challenging every add-back the seller leans on, because a soft adjustment multiplied by the entry multiple moves the price several times over. It means maximising the defensible debt-like items in net debt, and pinning down a working capital target that holds up. And I'd always tie findings back to price and to the SPA mechanism — because for PE, a finding that doesn't move the number or the contract isn't really a finding."

That answer signals you see the deal the way the client does — leading with the mindset, then grounding it in specific mechanics — which is precisely what separates a competent analyst from a memorable one.

The bottom line

Private equity clients are demanding for a reason: their entire return depends on the numbers you validate holding up under leverage and being sellable again in a few years' time. That pressure is exactly what makes PE diligence the fastest way to learn the craft. Absorb the mindset — lead with the answer, quantify the risk, tie everything to price and to the SPA — and you stop being an analyst who fills in a schedule and become one who thinks like the buyer. That shift is the whole difference, and PE clients will reward it with the most interesting, most consequential work you can do at this stage of a career.
