Waters Corporation (WAT) stock: Winston Score, insiders and Congress trades

Waters Corporation makes scientific instruments that help researchers and companies analyze the chemical makeup of substances. Their main products are liquid chromatography systems and mass spectrometers, which are machines used to separate and identify molecules. Pharmaceutical companies are their biggest customers, but they also sell to food safety labs, environmental testing facilities, and government research agencies. Waters earns most of its revenue by selling hardware instruments, along with recurring income from consumable supplies, software, and service contracts that keep those machines running. The company operates globally, with significant sales in the United States, Europe, and Asia, and generates roughly $3 billion in annual revenue. Its moat comes from the high switching costs of its specialized instruments and the long-term service relationships it builds with customers. The key growth driver is demand from pharmaceutical and biotech companies developing new drugs, though a slowdown in pharmaceutical spending or increased competition from rivals like Agilent and Thermo Fisher could pressure future results.
