The company buys another company or a business unit — products, customers and employees in one go, rather than building everything itself. The technical term for it is acquisition.
MoatLens tip: Acquisitions are the fastest way to grow — and the most expensive when too much was paid. Whether an acquisition paid off often shows only years later: does profit grow along with it, or is all that's left a large item of goodwill on the balance sheet? Regular small acquisitions paid for out of ongoing business read differently from a single giant purchase on debt.
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.
