The Most Common Red Flags in Due Diligence

An experienced due diligence team doesn't automatically treat every red flag as an alarm bell; the real skill is distinguishing which ones actually matter.

Signs of inconsistency in financial reporting

Significant gaps between audited financial statements and management reporting, or an auditor who has been changed frequently, are typically the first signals that trigger a deeper review.

Revenue unusually concentrated at quarter-ends (a "hockey stick" pattern) can sometimes indicate aggressive revenue recognition practices.

Customer and supplier concentration

Revenue overly concentrated in a small customer group can seriously threaten the business's future performance if one of those customers is lost.

Similarly, excessive dependence on a single critical supplier is a risk factor that can lead to unexpected supply chain disruptions after the deal closes.

Key personnel dependency

Business knowledge or customer relationships concentrated heavily in a single person (often the founder) creates serious value-loss risk if that person departs after the deal.

This risk is typically managed through key-person retention agreements or earn-out structures built into the deal.

Legal and regulatory compliance issues

Ongoing or recently closed lawsuits, disputes with regulators, or uncertainty around license renewal can directly affect the deal's timing and price.

Findings like these are typically addressed through specific indemnity clauses or an escrow deducted from the price.

Evaluating a red flag in context

The same finding can carry a completely different weight in different deal structures; for example, high customer concentration is far less concerning when backed by long-term contracts than in a business without contracts.

An experienced advisor evaluates every finding not as an isolated problem but as part of the deal's overall risk profile.

Frequently asked questions

Does finding a red flag automatically kill the deal?

No; it's typically managed through price negotiation, additional warranty requests, or a specific indemnity clause, depending on the severity of the finding.

What's the most commonly overlooked type of red flag?

Key personnel dependency; since it seems less tangible than financial findings, it's usually not taken seriously enough.

What's the best way to catch red flags early?

Starting due diligence as early as possible and holding open-ended, unstructured conversations with the management team.
