What Is Customer Concentration Risk?

A company can report impressive growth while depending heavily on a handful of customers. This creates customer concentration risk: the possibility that losing one or a few major customers materially harms revenue, cash flow or operations.

Practical Example

Suppose a supplier earns ₹1,000 crore in annual revenue, of which ₹350 crore comes from its largest customer. If that customer reduces orders by half, the supplier could lose ₹175 crore of revenue before considering replacement business or cost adjustments. The effect on profit may be larger if costs are fixed.

How Investors Can Analyse It

Analysts can examine customer disclosures, segment notes, contract duration, renewal terms, receivables concentration and management commentary. A high concentration is not automatically bad: long contracts, high switching costs and strong customer relationships may reduce risk. But concentration deserves a margin of safety and scenario analysis.

Important Interpretation

Revenue concentration is different from industry concentration. Several customers in one sector can all be affected by the same cycle. Investors should assess both customer-specific dependence and common end-market exposure. A useful checklist is to identify disclosed top-customer shares, assess contract durability, estimate replacement time, review payment behavior and stress-test a meaningful customer loss. Lack of disclosure should be treated as uncertainty—not proof of low concentration.
