Due diligence

Quick answer

Due diligence is the structured investigation of a business or asset before a transaction completes, covering financial, legal, commercial, tax, technical and operational matters. Buyers, investors and lenders use it to verify what they have been told, test valuation assumptions and identify risks or liabilities that should be reflected in price, structure or contractual protections.

Why it matters

Diligence findings frequently move price, terms or structure — and unresolved issues are a leading cause of failed transactions.

How it is used in transactions

Conducted in M&A, equity raises, debt financings and fund commitments, usually through a data room.

Due diligence verifies information before commitment, so problems can be reflected in price, structure or a decision to walk away. Warranties are contractual statements in the share purchase agreement that give remedies after completion if they prove untrue. Buyers use both: diligence to find issues, warranties to allocate residual risk.

Typically financial, legal, commercial, tax, technical and operational matters, usually investigated through a data room. The emphasis flexes with the transaction: lenders focus on cash flows and security, equity investors on growth assumptions and the cap table, and acquirers on liabilities, contracts and integration risk.
