What is Buy-Side Due Diligence?

Explanation of Buy-Side Due Diligence

Buy-side due diligence is conducted by or on behalf of an acquiring party in a merger, acquisition or investment transaction. Its purpose is to evaluate the target business and identify issues that may affect price, deal structure or post-transaction integration.

The process typically includes financial due diligence, which analyses historical performance, earnings quality, working capital and cash flow; tax due diligence, which reviews tax compliance, exposures and structuring considerations; legal due diligence, which examines contracts, liabilities and regulatory matters; and commercial due diligence, which assesses market position, customer base and growth prospects.

In the UK, findings from buy-side due diligence often inform share purchase agreements, warranties, indemnities and completion accounts mechanisms. It supports informed decision-making and helps purchasers understand both the risks and opportunities associated with the transaction.
