Is Waters Getting Expensive on Cash Flow?
The Discounted Cash Flow (DCF) model here takes Waters' projected free cash flows and discounts them back to today. Latest twelve month free cash flow sits at about $364.5 million, while analyst and model estimates have cash generation rising into the $2b range in the early 2030s before easing into more modest declines as the business matures. That pattern points to a company where much of the estimated worth is tied to cash produced many years out rather than the next couple of reporting cycles.
Those long runway assumptions matter because the DCF outcome sits meaningfully below the current trading level of $459.90. Recent Q3 2026 results beating expectations and the revenue guidance upgrade, helped by AI enabled products and proteomics acquisitions, help explain why the market is still willing to pay a premium over what the discounted cash flows alone support.
