A deal killer is not a very large red flag. It is a fact that has already been established and that no price adjustment can reach.

Almost every guide to this subject treats the untrue representation as the mildest category - a disclosure failure, remedied by updating a schedule and perhaps a specific indemnity - and the operational findings as the serious ones. That ordering deserves to be challenged. Operational problems are bounded, inspectable and mostly fixable; you can send an engineer, read a contract, and put a number on the answer. A counterparty whose written statements are not reliable is a different kind of exposure entirely, because the whole architecture of a private transaction rests on the assumption that what you were told is broadly true. Diligence checks perhaps a tenth of the assertions in a file; warranties are only as good as the person standing behind them and the cost of pursuing them; and the remaining nine tenths are held up by nothing except character. Discovering that the character is not there is not a small finding that happens to concern a small claim - it is a finding about the nine tenths. The reason it is so rarely treated that way is that it arrives attached to something trivial, and triviality is enormously persuasive.
The line between a red flag and a deal killer is drawn on two axes, and both have to be crossed.
First, it is established rather than ambiguous. A flag has two live explanations; a killer has one, because the document arrived and settled it. Second, it cannot be solved with money. That is the axis people miss. A great many serious findings are simply price: a deferred maintenance bill, an underfunded liability, a customer contract about to be renegotiated downwards. These are painful and they are negotiable, and treating them as fatal is how a buyer talks themselves out of good assets.
A deal killer is a finding for which no achievable price is correct. Either because it destroys the thing you were buying, or because it makes your exposure unbounded, or because it means the counterparty is not who you thought they were. The third category is different from the first two, and it is the one that has to be treated as absolute even when the sums involved are small.
Because without the distinction, every process ends in a negotiation about price, and some of them should not. A finding that makes the exposure unbounded cannot be settled with a discount, because there is no discount large enough when the range of outcomes has no floor - and a buyer trained to convert every problem into a number will reach for one anyway, because that is the move that keeps the process alive.
And because the categories are worth deciding in advance, in the quiet, rather than in the week of the deadline. A person who has written down what would end this for them is capable of recognising it when it arrives. A person who has not will be discovering the category and applying it simultaneously, under time pressure, having already spent money - and will almost always discover that this particular instance is a special case.

Four findings on the same 4,200,000-revenue manufacturer. Two are price. Two are not.
Price, one. A registered charge over the plant securing 380,000 of borrowing that was not in the summary. It is an encumbrance and it is real, but it is a known, bounded number: the debt is settled at completion from the proceeds, and the price moves by 380,000. Unpleasant discovery, ordinary resolution.
Price, two. The main production line needs 240,000 of work within eighteen months. That is a capital expenditure the seller did not mention and the buyer now knows about. It changes what the business is worth by roughly the amount of the bill, and there is a price at which it is fine.
Not price, one. The manufacturing licence that underpins the product accounts for 2,900,000 of the 4,200,000 of revenue - 69.0% of it - and the licence agreement terminates automatically on a change of control, at the licensor's option, with no obligation to renew. If it goes, the business you are buying is the remaining 1,300,000, which is a completely different company at a completely different price. And critically, the outcome is not yours to determine: it belongs to a third party with no obligation to you and no reason to negotiate before completion. You cannot price this, because you cannot bound it. You can only convert it into a condition - the licensor's written consent, obtained before completion - and if that consent cannot be obtained, there is nothing to buy.
Not price, two. The seller provided a schedule of litigation stating there was none. A public register shows a claim filed nine months ago. The claim itself may be trivial - it might settle for 15,000. That is not the finding. The finding is that a written representation made to you during the transaction was untrue about something the seller could not plausibly have forgotten. Every other statement in the file was made by the same person, and most of them you cannot check. The size of this particular claim is irrelevant to what it tells you about the value of everything else you were told.
The first mistake is inflating a price problem into a killer because the process has become exhausting. A 240,000 repair bill is a negotiation, and a buyer who kills a deal over it has usually decided to stop for other reasons and found a respectable one.
The second is the reverse and it is far more expensive: converting a genuine killer into a price. A licence that may terminate on change of control is not a discount, because the loss is not bounded and the decision belongs to somebody who is not in the room. The instinct to solve everything with a number is the single most common way a buyer talks themselves past the thing that later destroys the investment.
The third is treating an untrue representation as a small matter because the underlying item is small. The item is not the finding. What has been established is that statements made to you in this process are not reliable, and the representations you cannot verify vastly outnumber the one you happened to check.
The fourth is discovering the category under deadline. Write down what would end this before the process starts, when nothing has been spent and nobody is waiting on you.
Three to six items, specific to this asset: the thing whose loss would leave you owning something else entirely, the exposure with no upper bound, the counterparty behaviour you will not accept. Date it. This is the only version written by somebody with nothing invested.
If a number exists at which you would happily proceed, it is a negotiation. If no number exists because the downside has no floor, or because the asset stops being the asset, it is a killer. The question is binary and it takes one minute; the difficulty is asking it honestly rather than usefully.
A bounded liability you can settle is price. An outcome that belongs to a licensor, a regulator, a landlord or a lender with no obligation to you is not something you can price - it is something you can only make a condition of proceeding.
Consent obtained in writing before completion, a warranty with real substance behind it, a specific indemnity. A condition is only worth having if you are genuinely prepared to walk when it is not met, and a condition everybody knows you will waive is decoration.
Record what was stated, what the independent source showed, and the fact that both are true of the same person. Judge it on what it implies about the unverifiable remainder of the file, which is most of it.
In any transaction where you are relying on statements from a counterparty and where completion transfers something that a third party could withdraw - licences, leases, key contracts, permissions, regulatory approvals.
The category is not a licence to be theatrical. Declaring a killer is a strong move that ends a process and spends relationships, and a buyer who does it twice on ordinary price findings will not be shown the next opportunity. Reserve it for the two axes and be able to state which one was crossed.
A shape that recurs where transactions later fail badly is an unbounded risk that was resolved as a price adjustment. The mechanism is almost always a specific one: the risk is genuinely uncertain, a discount is the only instrument anybody in the room knows how to use, and the discount is set at the risk's expected value - a probability multiplied by an estimated cost. That arithmetic is sound for something that will happen many times and meaningless for something that happens once. A 30% chance of losing two thirds of the revenue is not a 20% discount; it is a fork, and one branch of it is fatal.
Expected value prices a risk you will take repeatedly. On a single transaction, ask what happens on the bad branch and whether you survive it - and if the answer is no, a discount is the wrong instrument however carefully it was calculated.
Change-of-control provisions sit in the middle of long contracts that nobody reads in full until the legal review, which is typically commissioned last because it is expensive. The commercial team has by then modelled the revenue those contracts produce, the price has been agreed in principle, and the term arrives into a process that has already concluded. It is also genuinely easy to miss on a skim: the clause is short, unremarkable in its drafting, and identical in appearance whether it governs 2% of revenue or 69% of it.
Ask for the assignment and change-of-control provisions of the largest contracts in the first wave, as an extract, before commissioning a full legal review. It is a cheap request and it is the one most likely to arrive too late to matter.
