A durable advantage that makes it hard for competitors to take a company's customers and profits. A strong brand, high switching costs, a network effect, a cost advantage nobody can copy.
MoatLens tip: The moat is the heart of what MoatLens looks for — but you never see it directly, only its traces in the numbers. High returns on capital across ten years. Margins that hold even in bad years. Price increases without losing customers. Where a company leaves those traces, there is usually a moat. Where they are missing, no amount of fine storytelling in the annual report helps.
The moat describes a company's durable competitive advantage — that is, what protects it from competitors.
Why does this matter?
Companies without a moat constantly have to fight for customers, often on price. That squeezes profits. Companies with a wide moat, by contrast, can earn high profits for years without new competitors displacing them.
Typical moats are: strong brands (e.g. well-known consumer products people reach for out of habit), network effects (e.g. platforms that become more valuable the more users they have), cost advantages from scale, high switching costs for customers, or patents.
MoatLens perspective: A core principle of value investing is: look for "castles with wide, durable moats" — companies that an intruder can only attack with difficulty. The moat is often considered one of the most important single factors in an investment decision, because it secures long-term earning power.
What to watch for: Ask yourself: why do customers buy from this company and not a competitor? If the answer is only "because it's cheaper," the moat is usually narrow or non-existent.
This is about the depth and durability of the moat – what protects the company from competitors. It complements the numbers with what becomes visible qualitatively in the report.
Why does this matter?
Metrics like high margins show THAT an advantage exists. The annual report shows WHAT it rests on and whether it holds: pricing power (customers pay more without leaving), switching costs (changing is hard or expensive), brand strength, network effects.
What MoatLens looks at:
Is the advantage structural and durable – or easily attacked? Is the moat widening or eroding? A broad, stable advantage marks it up, a fading one marks it down.
In MoatLens this explanation sits right next to the number — one tap away. And you see the ten-year trend instead of a single value.
