Approach 1: Ecolab Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what Ecolab stock might be worth by taking its projected future cash flows, then discounting those back to today’s value in $ using a required return. The idea is simple: cash generated in future years is worth less than cash received today.

For Ecolab, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month Free Cash Flow (FCF) is about $2.0b. Analyst estimates and subsequent extrapolations suggest FCF in 2028 of $2.47b, with intermediate annual projections such as $1.87b in 2026 and $2.40b in 2027. Beyond the analyst horizon, Simply Wall St extrapolates FCF through to 2035, with each year discounted back to reflect the time value of money.

Adding these discounted cash flows together produces an estimated intrinsic value of about $207.51 per share under this DCF model. Against the recent share price of $276.29, this implies the stock is about 33.1% above that estimate, which points to Ecolab trading at a premium on this cash flow view.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Ecolab may be overvalued by 33.1%. Discover 44 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Ecolab Price vs Earnings

For profitable companies like Ecolab, the P/E ratio is a widely used benchmark because it links what you pay for the stock to the earnings the business is currently generating. It gives a quick sense of how much investors are paying for each dollar of earnings.

What counts as a “normal” or “fair” P/E ratio usually reflects two things: how quickly earnings are expected to grow and how risky those earnings are perceived to be. Higher growth or lower perceived risk can justify a higher multiple, while slower growth or higher risk often lines up with a lower one.

Ecolab currently trades on a P/E of 36.93x, compared with an average of 23.26x for its peer group and 25.73x for the broader Chemicals industry. Simply Wall St also provides a proprietary “Fair Ratio” estimate of 24.70x, which incorporates factors such as Ecolab’s earnings profile, industry, profit margins, market value and risk characteristics.

This Fair Ratio can be more informative than a simple comparison with peers or the industry because it is tailored to the company’s own fundamentals rather than relying only on group averages. Set against the current 36.93x multiple, the 24.70x Fair Ratio suggests Ecolab stock is trading above that fair value estimate.

Result: OVERVALUED
