Air Liquide (ENXTPA:AI) Stock Looks Overvalued As Its 77% Run Continues

L'Air Liquide has delivered a strong share price run in recent years, and the question now is whether the cash the business is expected to generate really backs up where the stock trades today. With investors watching its push into hydrogen and gases for energy and AI infrastructure, the focus turns to what those projects mean for long term cash flows rather than just headlines.

• Over the past 5 years, L'Air Liquide has returned 76.7%, which puts real weight on whether the current share price is aligned with the cash the business can produce over time.
• New projects such as the Normand'Hy green hydrogen facility and infrastructure for ExxonMobil's low carbon hydrogen plans can reshape when cash comes in and how much investment needs to go out first, which matters directly for any cash flow based valuation.

Is L'Air Liquide Getting Expensive on Cash Flow?

The Discounted Cash Flow (DCF) model here focuses on the cash L'Air Liquide can return to shareholders over time. Latest twelve month free cash flow is about €1.9b, and the projections used in the model assume that free cash flow grows steadily into the early 2030s rather than swinging sharply up or down. That pattern fits a mature industrial group with heavy capital needs, where new hydrogen and gas infrastructure projects must be funded before they feed into future cash generation.

On those cash flow assumptions, the DCF points to an estimated intrinsic value that sits substantially below the current share price of €182.04. The market is effectively putting a richer price on each euro of projected free cash flow than the model does, which matters if you see hydrogen and AI related gas demand as either already well reflected in the quote or as having more room to surprise. Air Liquide's push into projects like Normand'Hy starting production in the coming weeks helps explain why investors may be comfortable paying up despite what this valuation view suggests.
