The sector median covers every company in the sector on the US market, loss-making ones included.
Ecolab sells cleaning and water treatment to businesses — with service attached, not as a commodity.
Customers are restaurants, hotels, hospitals, food producers and industry. The company supplies not a drum of chemicals but a system: dosing equipment, staff training, consumption monitoring and a guaranteed hygiene outcome. It is the service that makes switching inconvenient and holds price.
Water treatment is the second large and structurally growing line: industry is obliged to cut water use and discharge, and water costs are rising. Selling savings rather than reagent allows charging for the result.
Costs depend on raw material and energy prices, and during inflation the company raises prices with a lag. Demand is durable: hygiene is mandatory in downturns too. Ecolab is a dividend aristocrat with a long record of increases.
