Landing a major customer can transform a company.
Revenue jumps, capacity utilisation improves, and earnings become easier to forecast.
But investors should not automatically interpret a large customer as purely positive.
Imagine a manufacturer where one client contributes 45% of sales. As long as orders keep coming, the relationship looks fantastic.
But that customer also knows how important it is. When the next contract is negotiated, who has more bargaining power?
The customer may demand lower prices, longer payment terms, or additional services.
Worse, if it changes supplier, delays an order, or moves production elsewhere, a large portion of the company’s revenue can disappear almost overnight.
Customer concentration is therefore a trade-off. A major client can validate a business and accelerate growth, but excessive dependence creates fragility.
The better question is not simply, “Who are their biggest customers?” Ask instead: “If the biggest customer leaves tomorrow, what happens to earnings?”
