How FDD priorities invert when a target is financially distressed - going-concern risk, compressed cash-driven timelines, and why cash runway, not EBITDA, becomes the question.
Almost everything you learn about financial due diligence quietly assumes a healthy business. The whole exercise - normalising earnings, adjusting EBITDA, agreeing a working-capital target - is built to help a buyer pay a fair price for a company that is going to keep existing. Distressed M&A tears that assumption up. Here the target may not survive without a transaction at all, and when survival is genuinely in question, the diligence you run and the questions you ask flip on their head.
This is not standard FDD done faster. It is a different discipline with a different centre of gravity, and understanding how the priorities shift is valuable even if you spend most of your career on healthy deals - because distress can surface mid-process on any transaction if the numbers turn.
In a standard deal the central question is, roughly, what is this business worth, and what is a fair price? In a distressed situation a prior question comes first and dominates everything else: can this business survive long enough to complete a transaction at all?
That single shift reorders the entire engagement. The normalised EBITDA analysis that usually anchors a quality of earnings review recedes; short-term cash - weekly, sometimes daily runway - moves to the front. A distressed target can have a perfectly analysable historical P&L and still run out of money before signing, if working capital unwinds or suppliers tighten terms during the process. Historical profitability tells you what the business was. In distress, the only question that matters first is whether it makes it to completion.
In a healthy deal, cash is a workstream. In a distressed deal, cash is the workstream - everything else is contingent on the business still being solvent when the deal closes.
Because solvency is the binding constraint, the centrepiece of distressed diligence is a short-term cash flow forecast - typically a 13-week model, built from the bottom up on actual receipts and payments rather than accrual-based earnings. Thirteen weeks is the convention because it is roughly one quarter: long enough to see the pattern, short enough to model week by week with real granularity.
You are not forecasting profit. You are forecasting the bank balance, week by week, and asking a blunt question: does it go negative, and if so, when?
| Week | Opening cash | Receipts | Payroll | Suppliers | Other | Closing cash |
|---|---|---|---|---|---|---|
| 1 | €1.20m | €0.85m | (€0.40m) | (€0.55m) | (€0.10m) | €1.00m |
| 2 | €1.00m | €0.70m | - | (€0.60m) | (€0.10m) | €1.00m |
| 3 | €1.00m | €0.60m | (€0.40m) | (€0.50m) | (€0.10m) | €0.60m |
| 4 | €0.60m | €0.55m | - | (€0.65m) | (€0.10m) | €0.40m |
| 5 | €0.40m | €0.50m | (€0.40m) | (€0.45m) | (€0.10m) | (€0.05m) |
Read that model and the story is immediate: the business runs out of cash in week 5, at the next payroll. That single fact drives the entire transaction. It sets the real deadline - not the seller's preferred timetable, but the point of insolvency. It tells the buyer how much bridge liquidity is needed and when. And it reframes every other finding: an EBITDA add-back is irrelevant if the company cannot make payroll in a month. This is why the cash model, not the earnings analysis, is where distressed diligence begins and where the negotiating leverage lives.
Distressed deals move on genuinely compressed timelines - sometimes weeks rather than the months of a standard financial due diligence process. Critically, the clock is set by cash runway, not by a seller's auction dynamics. The 13-week model does not just inform the diligence; it is the deadline.
That compression forces a scope decision. Distressed FDD is, by necessity, closer to a red-flag review than a comprehensive engagement. You triage ruthlessly for the issues that can kill the deal or the buyer - cash position, immediate liabilities, going-concern risk, security and creditor priority - and you consciously accept lighter coverage elsewhere. Attempting the full, meticulous normalisation of a healthy-business engagement is not diligence in this context; it is a way to run out of time before you have answered the question that actually matters. Knowing what to skip is as much a skill here as knowing what to examine.
A distressed engagement almost always includes an explicit going-concern assessment: does the business have enough liquidity, or a credible path to enough liquidity, to keep operating without a rescue transaction? This demands far more forward-looking, granular cash modelling than a standard historical net debt bridge. You are not just measuring what is owed today; you are testing whether the business can meet its near-term obligations - payroll, critical suppliers, rent, tax - at all.
The analysis also has to identify what would change the answer. Is there undrawn facility headroom? Could a supplier standstill buy weeks? Would an accelerated receivables push move the cliff-edge? Distressed diligence is not only diagnostic; it is about mapping the levers that keep the patient alive long enough for the transaction to complete.
A subtlety that catches out analysts trained on healthy deals is that some of the standard adjustments actively mislead in distress. Take normalisation: in a healthy engagement you happily add back one-off restructuring costs to arrive at a "clean" run-rate. In a distressed situation those very costs may be recurring, because the business is in perpetual firefighting mode - and the cash to fund them is real, imminent, and non-discretionary. Adding them back to flatter EBITDA while ignoring their cash drain would tell precisely the wrong story. Similarly, deferred payments to suppliers and tax authorities can make a period's cash position look artificially healthy, when in reality the business is simply stretching creditors it will soon have to pay. Distressed diligence demands that you read every apparent improvement in the numbers with the question: is this genuine, or is it borrowed from next month?
Distress changes how customers and suppliers behave, and that creates genuine analytical noise. Once counterparties sense trouble, suppliers tighten terms or demand cash-on-delivery, customers delay orders or quietly line up alternatives, and both reactions accelerate the cash crunch independently of the underlying operating performance. This is where standard working capital analysis gets treacherous.
The central judgement is distinguishing a temporary, stress-driven working-capital deterioration from a structural decline in the business. A supplier moving you to COD is a liquidity shock, not necessarily evidence the product is failing; a customer leaving because your service has genuinely degraded is structural. In healthy diligence you rarely have to separate these - in distress it is one of the hardest and most important calls you make, because it determines whether the business is fundamentally viable or merely illiquid. The revenue quality lens still applies, but you are applying it through a fog of stress-induced behaviour that muddies every trend.
Distressed situations usually involve multiple layers of creditors - senior secured lenders, subordinated debt, sometimes trade creditors owed material sums - each with different priorities and different leverage in a negotiation. Understanding the debt structure and covenant position is not merely an input to a net-debt bridge here; it shapes which transaction structures are even feasible.
Senior lenders often hold consent rights over any sale, and their appetite - repayment in full, a haircut, an equitisation - effectively defines the deal envelope. Security ranking determines who gets paid in what order if the business fails, which sets each stakeholder's walk-away point and therefore their negotiating stance. An analyst who cannot map the creditor waterfall cannot tell the buyer what is actually achievable. This is where the financing and legal picture stops being background and becomes the deal itself.
Distressed M&A rewards a different profile from standard FDD. Speed, cash-flow fluency, and comfort operating on incomplete information matter more than the meticulous, comprehensive normalisation that defines a healthy-business engagement. You are making consequential calls with partial data under a hard deadline, which is uncomfortable for anyone trained to reconcile everything to the penny before forming a view.
It is a smaller, more specialised niche - but the mindset transfers. Even on healthy deals, the ability to build a quick short-term cash view, triage for what actually threatens the deal, and read a creditor structure is a genuine hard skill, and the calm-under-pressure temperament it demands is a soft skill that shows up in every engagement. Distress can emerge mid-process on any transaction if trading turns, and the analyst who has thought about it in advance is the one who does not freeze when it does.
Distressed questions are excellent discriminators because they reveal whether a candidate can re-prioritise under pressure or only knows the standard playbook. A typical prompt: "You're brought in on a distressed target. Where do you focus, and how is it different from a normal deal?"
"The first thing I'd do is mentally park the normalised EBITDA work, because in distress the prior question is whether the business survives to completion at all. So I'd lead with a short-term cash flow forecast - a 13-week model built on actual receipts and payments, not accruals - to find out when, if ever, the business runs out of cash. That model sets the real deadline for the whole deal. From there I'd run an explicit going-concern assessment: is there facility headroom, could a supplier standstill or a receivables push buy time, what are the levers? I'd map the creditor structure carefully, because senior lenders usually have consent rights and the security ranking defines what's even achievable. And I'd be very careful reading working capital, because distress distorts it - suppliers going to cash-on-delivery is a liquidity shock, not proof the business is broken, and separating temporary stress from structural decline is the hardest judgement here. Compared with a normal deal, I'd consciously accept a red-flag scope rather than full coverage - with weeks not months, triaging for what can kill the deal beats trying to normalise everything. Cash, not earnings, is the centre of the whole exercise."
That answer lands because it inverts the standard priority explicitly, names the 13-week model as the anchor, and shows the candidate understands why the scope narrows rather than just asserting that it does.
Standard FDD asks what a business is worth. Distressed FDD asks, first, whether it will still exist by completion - and only then, if the answer holds, what it is worth. That inversion changes everything: cash leads, earnings recede, scope narrows to what can kill the deal, and the creditor structure becomes the deal itself. It is a specialised corner of the field, but the discipline it teaches - lead with cash, triage under pressure, form a view on incomplete information - is exactly the temperament that makes an analyst valuable when a healthy deal suddenly stops being one.
The Transaction Services Interview Programme (€119.99, one-time) includes a distressed-M&A module: building a 13-week cash flow model from scratch, structuring a going-concern assessment, and reading a creditor waterfall - with the worked runway example above as a guided exercise. Enrol today.
Hundreds of candidates prepared their interviews with this programme. Those who landed the role have one thing in common: they worked the cases before walking into the room.
