Due diligence findings and how they change the price: what to do in the first days after the report lands turns on three things: the price mechanism in the agreement, the materiality threshold that triggers adjustment, and whether the finding is classified as a warranty breach or a disclosed, allocated risk. Get the classification right before attaching a number.
Who this concerns
Buyers and sellers in a Swedish share or asset deal where due diligence turns up something that was not priced into the original offer: undisclosed debt, a customer concentration issue, a permit that was never renewed, a warranty claim sitting with a supplier. This concerns anyone between signing and closing, or between the data room closing and the purchase price becoming final, because that is the only window in which findings can still move the price. It also concerns the party on the other side of the table, because a finding raised late and badly evidenced does not automatically translate into a lower price: it has to survive negotiation and, if it does not, litigation.
The mechanics differ depending on where the counterparty, the target's assets or a parent company sit. Cross-border deals often carry a locked-box price fixed months before closing, an escrow held in a different jurisdiction, or a warranty and indemnity insurer domiciled outside Sweden, and each of these changes who has to be notified, in what form and by when. A due diligence finding that would be straightforward to price in a purely domestic deal can become a jurisdiction question first and a valuation question second once a foreign parent guarantee or a foreign governing law clause is in play.
This sits within the broader mechanics of contracts and transactions work: the price mechanism is a contract term like any other, and it is negotiated, drafted and enforced the same way.
What the law says
Under Swedish law as it currently stands, there is no statutory formula for adjusting a purchase price after a due diligence finding. The adjustment lives entirely in the agreement: in the definition of the price mechanism, in the warranty catalogue, in the disclosure letter and in the indemnity clause. General principles of contract law, including good faith in performance and the rule that a party generally cannot rely on a fact it already knew or should have discovered, apply as a backdrop, but they do not replace what the contract itself says.
That makes the drafting stage, not the courtroom, the place where most of these disputes are actually decided. A finding that falls inside a properly drafted, broad warranty with no knowledge qualification is a strong claim. The same finding, discovered after the buyer had access to the relevant file in the data room and signed anyway, is a weak one, because Swedish contract practice generally treats actual knowledge as capable of narrowing or defeating a warranty claim unless the agreement says otherwise.
How it works in practice
Classify the finding before attaching a number
The first task is not valuation. It is classification: is this a breach of a specific warranty, a breach of a general disclosure obligation, a matter covered by an indemnity, or a risk that was disclosed and therefore already allocated to the buyer. Each classification opens a different route and a different remedy, and they are not interchangeable. Treating every finding as automatically warranty-actionable is the single most common overreach on the buy side.
Locked box or completion accounts: different levers move
In a locked-box deal the price is fixed at signing by reference to a set of accounts, and anything that moves value between the locked-box date and closing is dealt with through leakage protection and interest, not through a fresh valuation. A due diligence finding in that structure usually has to be routed through a warranty claim or an indemnity, because the price mechanism itself has no room for renegotiation. In a completion accounts deal the price is only fixed after closing, against accounts prepared at that point, and a finding discovered during that preparation can move the number directly, through the accounts, before it becomes a separate claim at all.
Warranty breach versus disclosed, allocated risk
A finding that was flagged in the disclosure letter, referenced in a specific indemnity, or covered by a data room document the buyer had access to is not automatically a warranty breach. It may be a risk the buyer priced in, knowingly or not. Sellers routinely argue this point as a full defence. Whether it succeeds depends on how the disclosure was worded and whether it was specific enough to put the buyer on notice of that particular fact, not just the general category.
Building the quantification
A finding is not a number until it has been converted into one using a defensible method: replacement cost, lost profit, a multiple applied to a recurring liability, or the cost of remediation supported by evidence. Quantification built on assumption rather than on invoices, valuations or third-party quotes is the first thing a counterparty's advisers will attack, and it collapses fast in negotiation if it cannot be traced to a document.
A finding that points to a capital shortfall in the target, rather than a one-off liability, raises a separate question under Swedish company law: whether the target's board should already have prepared a kontrollbalansräkning, the statutory control balance sheet triggered when equity falls below a defined fraction of registered share capital. If that obligation was missed before closing, it is a finding in its own right, independent of the price adjustment.
Notice requirements and preserving the claim
Most Swedish share purchase agreements set a contractual notice period for warranty and indemnity claims, running from discovery or from closing, and missing it extinguishes the claim regardless of its merits. The notice itself typically has to describe the breach and, where possible, give a good-faith estimate of loss; a vague notice sent purely to preserve a deadline, without real content, is often challenged as insufficient.
Negotiating an adjustment versus pursuing an indemnity
A price reduction agreed before closing is cleaner than an indemnity claim pursued after closing, because it avoids a second negotiation over causation, mitigation and quantum months later. Where closing cannot be delayed and the finding cannot be fully quantified in time, an escrow holdback tied to the specific finding, released on a defined trigger, is the usual middle ground.
What to check before the number is put forward
- Which specific warranty, if any, the finding falls under, and whether it carries a knowledge qualification
- Whether the fact was in the data room, the disclosure letter or otherwise made available to the buyer before signing
- The contractual notice period and the form the notice must take
- Whether the price mechanism is locked box or completion accounts, and which remedy route that leaves open
- Whether the finding also triggers a separate statutory obligation, such as a control balance sheet requirement
- Whether the counterparty, the relevant assets or a guarantor sit in a different jurisdiction, and what that changes for service and enforcement
- The evidentiary basis for the number: invoices, valuations, third-party quotes, not internal estimates alone
Related mechanics worth checking before the price is finalised
Where the deal includes deferred consideration, a finding discovered after closing frequently resurfaces as an earn-out dispute after closing, because the same fact that would have justified a price cut pre-closing is instead argued as grounds to reduce the earn-out payment. The documentation required to support a finding at the screening stage overlaps closely with what a buyer should assemble during investment screening before closing, and a finding involving intellectual property developed by target employees raises its own separate deadline under the rules on employee invention compensation.
Frequently asked questions
#### What documents should back up a due diligence finding before it is put to the other side?
Anything that turns the finding into a defensible number: the underlying contract or permit, invoices or quotes for remediation cost, and a dated record of when the fact was discovered. A finding built on assumption rather than paper is the first thing a counterparty's advisers will attack.
#### Does a due diligence finding discovered after closing still affect the price?
It can, but only through the mechanism the agreement provides for it, typically a warranty claim, an indemnity, or an adjustment to deferred consideration where part of the price is paid on an earn-out basis after closing rather than a reopening of the original completion price.
#### Does a finding involving employee-developed intellectual property need separate handling?
Yes. Beyond the price question, it can trigger the target's own compensation obligation toward the inventor, which runs on a different clock from the transaction and does not disappear because the finding was also used to negotiate the price.
The numbers
There is no statutory percentage that fixes when a finding is material enough to move the price. That figure, together with the de minimis threshold, the aggregate basket and the cap, is negotiated deal by deal and set out in the agreement, not in legislation. The same is true of the notice period for claims and the survival period for warranties: both are contractual defaults that vary from one agreement to the next, and the applicable figure is the one written into the specific contract in front of you, not a market average.
The time a dispute over a finding takes to resolve, whether through negotiation, expert determination or litigation, is not fixed by rule either. It depends on the complexity of the quantification, the caseload of the relevant court if it gets that far, and how complete the supporting file is when the claim is first raised.
Where it usually goes wrong
The most common failure is timing: a finding surfaces, is discussed informally, and the formal notice under the agreement is never sent within the contractual window, because everyone assumed the conversation itself preserved the claim. It does not, unless the agreement says a different form of notice is sufficient.
The second is knowledge. A buyer that had the relevant document in the data room, or that raised the issue during due diligence and then signed without a specific carve-out, has usually weakened or lost the claim, because Swedish contract practice treats that access as notice absent a clear clause preserving the right to claim regardless of actual knowledge.
The third is quantification built backwards from a target discount rather than forwards from evidence. A number produced to justify a desired price cut, rather than derived from the underlying cost, is the first thing that unravels once the other side asks for the supporting file.
The fourth is cross-border enforcement. A warranty claim against a foreign seller, or an indemnity against a foreign parent guarantor, can be contractually sound and practically very difficult to enforce if the counterparty has no assets reachable from a Swedish judgment and the governing forum clause was not drafted with that scenario in mind.
The fifth is treating a capital adequacy problem purely as a warranty issue. If the finding reveals that the target's equity was already below the statutory threshold before closing, the board's own control balance sheet obligation is a separate exposure that does not disappear once the price has been adjusted.
What to do next
Working through these mechanics alone reaches a limit at the point where the finding has to be converted into a number that will hold up if challenged, and where the correct claim route through the specific agreement has to be identified with certainty rather than assumed. That is where an assessment of the position, contact Lodline, replaces guesswork with a reading of the actual documents.
Where the finding sits inside a construction-related contract governed by AB 04 or ABT 06, the cost exposure usually needs separate treatment from the general price adjustment question: see construction contract cost exposure under AB 04 and ABT 06.
