Enter a ticker to learn what the company does and how it makes money.
IDEX makes small but essential pumps, valves, and fluid-handling parts that go into many different machines and factories.
IDEX Corporation is a collection of niche industrial businesses, and it sells to other companies rather than to regular shoppers. Its main customers are factories, chemical plants, water utilities, farms, fire trucks, and medical device makers. The company splits into three broad parts: fluid and metering technologies, health and science technologies, and fire and safety equipment. Think of it as the maker of the unglamorous but critical bits—a tiny pump inside a dialysis machine, a valve on a fire truck, a precise dispenser at a chemical plant—that make bigger systems work. Founded in 1988 and based near Chicago, it grew by buying lots of small, specialized companies and letting them keep their own brands while sharing costs. That buy-and-hold style is the heart of how it makes money.
Most revenue comes from those fluid and metering businesses, which are the biggest slice by far, with health and science and fire and safety making up the rest. These products often sit inside larger equipment, so once a customer designs an IDEX part into a machine, switching is annoying and expensive. That stickiness gives the company steady, high-margin sales and lots of free cash. It tends to use that cash to buy more small companies, pay a rising dividend, and buy back its own stock, which gradually shrinks the share count.
Lately the story is about steady growth plus bolt-on deals. Management has kept buying family-owned or founder-run manufacturers to add new niches, often ones tied to health care, water, and clean energy. The risk is simple: industrial demand rises and falls with the economy, and some of its markets have been soft, so growth has cooled. Still, the basic idea is a quiet compounder—own the little parts everyone needs, charge a fair price, and keep rolling the cash into the next acquisition.
