IDEXX makes diagnostics for veterinary clinics — analysers and tests for animals.
The model matches laboratory equipment: an analyser is placed in a clinic and its test strips and reagents are bought for years. The machine works only with proprietary consumables, so the installed base is the source of recurring revenue.
Demand is set by how much owners spend on animal health, a figure that grew for decades faster than consumer spending generally. The flip side is that pet spending is discretionary: in a prolonged downturn routine check-ups are postponed. A clinic with its own analyser gets results in minutes instead of sending a sample to an outside laboratory — that is where the lock-in comes from. The company pays no dividend, directing cash into buybacks.
