What is financial due diligence?

Definition

Financial due diligence: The review of a target's historical results, cash flow, working capital and debt to confirm the earnings a buyer is paying for and spot adjustments that affect price.

How it works in a data room

Accountants working for the buyer, or for the seller in vendor diligence, request monthly management accounts, audited statements, trial balances, revenue by customer and product, payroll, capital spending and debt schedules. These are typically held in the finance section of the room, with large spreadsheets kept in native format for analysis but often restricted from download until the later rounds. Questions about one-off items or accounting policies go through the Q&A tool, and the answers are referenced in the final report.

Why it matters in a deal

Valuation usually rests on a multiple of normalized earnings, so every adjustment matters. A quality of earnings analysis may strip out non-recurring income, add back owner costs or reveal aggressive revenue recognition. Working capital and net debt definitions drive the final purchase price mechanics, so they are often negotiated using numbers found in the room. Our private equity guide explains why sponsors scrutinize this workstream so closely.

Example

During diligence on a Canadian commercial printing business, the buyer’s accountants find that one large contract was billed early to boost year-end revenue. After adjusting for it and for seasonal working capital swings, normalized earnings fall by about 8 percent. The seller accepts a lower price rather than restart the process.
