L'Air Liquide (ENXTPA:AI) Expands In Vietnam And New Projects Build, Is It Fully Priced?

L'Air Liquide: Why Fresh Projects Matter Now

L'Air Liquide (ENXTPA:AI) is back in focus after a cooperation deal with Vietnam's Vinachem and fresh spending on semiconductor gases and biomethanol projects, spotlighting its long-term decarbonisation and industrial growth agenda.

Recent news around L'Air Liquide’s Vinachem partnership and new capex plans lands on top of a strong backdrop, with a 1-month share price return of 4.29% and a year-to-date share price gain of 20.85%. The 5-year total shareholder return of 76.84% points to momentum built over several years.

After that strong run and fresh project pipeline, the central question for L'Air Liquide is straightforward: does the current price still leave enough potential upside in the risk‑reward balance for new money?

Preferred P/E of 31.4x: Is it justified?

L'Air Liquide currently trades on a P/E of 31.4x, which is well above several benchmarks even though the SWS DCF model points to a fair value of €181.65 versus the recent €174.68 share price.

The P/E ratio compares the share price with earnings per share and shows how much investors are paying today for each euro of profit. For a mature gases and engineering group with global reach, a higher P/E can signal that the market is comfortable paying up for earnings quality, balance of industrial and healthcare exposure, and a long operating history.

For L'Air Liquide, the data suggests that optimism comes at a clear premium. The stock is described as expensive on a P/E of 31.4x versus a fair P/E estimate of 24.3x. This is a level the market could eventually move towards. It is also labelled expensive relative to the European chemicals sector on 16.7x and against a peer average of 18.9x. Buyers today are therefore accepting a materially richer valuation than both the sector and peer group.

Result: Price-to-earnings of 31.4x (OVERVALUED)

Still, L'Air Liquide’s premium P/E looks exposed if large project returns lag expectations or if industrial and healthcare end markets weaken from current conditions.

Another View: What The SWS DCF Model Says

The SWS DCF model paints a softer picture than the rich 31.4x P/E. On this approach, L'Air Liquide looks modestly undervalued, with a fair value of €181.65 against the current €174.68 share price, which implies a 3.8% discount rather than a premium story.

That kind of gap is not huge. Yet it suggests the P/E premium might be less about froth and more about the market leaning toward the cash flow outlook. The open question for you is simple: Which signal carries more weight, the earnings multiple or the cash flow model?

Look into how the SWS DCF model arrives at its fair value.
