Customer concentration

The share of a company’s revenue attributable to its largest customers. The risk depends on contracts, customer quality, profitability and the difficulty of replacing lost business, not a universal percentage threshold.

Customer concentration in round numbers

Hypothetical: revenue from the top customer is 34% of total revenue for the same annual period and reporting scope. The percentage describes concentration; it does not by itself establish whether the exposure is acceptable or requires repricing.
