Financial due diligence helps buyers, investors and funders understand the true financial position of a business before committing to a deal. By identifying potential risks and validating key assumptions, it can provide greater confidence that an investment represents value and aligns with strategic objectives.
What is financial due diligence?
Financial due diligence is an independent review of a company’s financial performance, position and key commercial drivers before a deal takes place.
Rather than simply reviewing a set of accounts, financial due diligence looks behind the numbers to assess a business’s financial health and identify any risks that could impact value or future performance.
When is financial due diligence used?
Financial due diligence is commonly undertaken as part of:
- Business acquisitions
- Mergers
- Management buyouts (MBOs)
- Management buy-ins (MBIs)
- Private equity investments
- Strategic investments
It can also be valuable for business owners preparing for a future sale, helping identify issues that could affect value or slow the sales process.
What does financial due diligence look at?
The scope of a financial due diligence exercise will vary depending on the deal, but it typically includes a review of:
- Financial performance and profitability
- The quality and sustainability of earnings
- Cash flow generation
- Working capital requirements
- Existing debt and liabilities
Why is financial due diligence important?
While a business may seem attractive on paper, financial information does not always tell the full story.
Financial due diligence can uncover issues that may affect the value or future performance of a business, including weaknesses in financial reporting, cash flow concerns, unexpected liabilities and working capital pressures.
By identifying these matters before a deal completes, decision-makers can negotiate with greater confidence, reduce risk and avoid costly surprises after completion.
In some circumstances, findings from a financial due diligence review may influence the purchase price, the structure of the deal or even whether the acquisition proceeds at all.
Who should consider financial due diligence?
Financial due diligence can provide valuable insight for:
- Businesses looking to acquire another company
- Owner-managed businesses making their first acquisition
- Organisations following a buy-and-build strategy
- Funders requiring additional financial assurance
- Management teams involved in an MBO or MBI
- Business owners preparing for a future sale
