Mettler-Toledo makes tools that weigh and measure, and it sells them through three businesses. The largest, about 56% of sales, serves labs. Its balances can sense one ten-millionth of a gram. Beside them sit pipettes, the hand-held tools that move exact drops of liquid, and devices that test how acid, wet or dense a sample is.
The second business serves factories. It sells large scales, along with machines that check packed goods for bits of metal or other faults. A small third business sells the shop scales that print price labels.
The buyers are drug makers, food producers, chemical firms, colleges, shops and freight companies. No single customer brings in more than 1% of sales.
Much of the money comes after the sale. A drug company's lab buys a balance once. For years afterward, it pays Mettler-Toledo to check and adjust that balance, buys spare parts and keeps ordering fresh pipette tips. The company thinks it has more weighing tools in use than anyone else in the world. Service rose from 23% of sales in 2023 to 25% in 2025.
Looking ahead, Mettler-Toledo is counting on Spinnaker, its plan to win more sales by selling and marketing better. It also relies on new products, such as a device launched in 2026 that finds germs in liquids while they flow through a plant. The company calls its markets crowded, with cheaper rivals rising in developing countries.
In our reading, the steady service income suggests a business that holds up when orders for new machines slow. That income says less about whether the industries Mettler-Toledo serves are growing on their own.
