Why preparatory due diligence matters before selling the company

Identifying contingencies before the buyer does changes price, timing and holdback.

In short

  • A contingency found by the buyer may be reflected as a discount on the price.
  • Preparatory diligence acts on the three variables that destroy the most value, price, timing and holdback.
  • Much of what is found can be fixed.

From an informational standpoint, selling a company is an asymmetric contest in which the seller starts ahead. The seller knows the business and the buyer does not. But it is the buyer who defines the scope and presents the findings.

Preparatory diligence reverses that dynamic. The seller examines its own company with the rigour with which it will be examined, fixes what can be fixed, quantifies what cannot and comes to the negotiation knowing what the buyer will find. This is not an exercise in diligence for its own sake. It is the intervention with the best cost-to-effect ratio on the final price of a transaction.

Preparation acts on three variables, and it is worth separating them because they behave differently.

The first is price. A contingency found by the buyer's diligence turns into a reduction claim. The same contingency, identified beforehand and presented with its own quantification and defence history, can be discussed at another moment, which makes it easier to address in the agreement.

The second is timing. Diligence that uncovers corporate disorder, unkept books, unregistered minutes, unpaid capital or a poorly documented chain of title generates not only a discount but delay for remediation.

The third is the holdback. Organized information reduces uncertainty, and less uncertainty means a smaller holdback.

What to examine

Scope varies by sector and size, but there is a core that recurs and whose absence is felt in practically every transaction.

WorkstreamWhat usually surfaces

ContractsChange-of-control clauses requiring prior consent, forgotten exclusivities, expired agreements still being performed, guarantees granted to third parties
LabourClassification of contractors, working hours and time banking, payments of contested nature, pending claims and settlement history
TaxUse of credits, tax benefits without documentary support, ancillary obligations, instalment plans and their effect on the transaction
Real estate and environmentTitle records and occupancy, expired or pending permits, unmet conditions, site liabilities
Intellectual property and dataTitle to trademarks and software, assignment of rights by employees and third parties
CompliancePolicies actually applied, dealings with public officials, donations and sponsorships, whistleblowing channel

What preparation produces

  1. A contingency report with quantification, likelihood of loss and the company's defended position, which serves as the basis for the negotiation.
  2. A remediation plan separating what is fixed before the sale, what is fixed during it and what will remain as risk to be allocated contractually.
  3. An organized data room, which shapes the buyer's perception of how the company is run.
  4. Preliminary disclosure schedules, which substantially shorten contract negotiation and narrow the room for argument about what was or was not known.
  5. A defined negotiating position on cap, survival and holdback, built from known contingencies rather than estimates.
