Air Liquide stock holds on to margin gains and 2025 growth

Air Liquide (FR0000120628) remains anchored by its 2025 reporting base, where revenue reached EUR 27.06 billion and recurring net profit rose 9.1% to EUR 3.15 billion. The group also posted a 27.8% operating margin and said recurring net income per share increased 9.9% in 2025, giving Air Liquide stock a clear fundamental reference point.

EUR 27.06 billion in revenue

For 2025, Air Liquide reported EUR 27.06 billion in revenue, up 2.6% on a comparable basis, while published Group sales came in at EUR 27,060 million. The company also reported 2025 recurring net profit of EUR 3.15 billion, compared with EUR 2.89 billion a year earlier, a rise of 9.1% that outpaced the top-line growth.

That spread matters because it shows the earnings mix improving faster than revenue. Air Liquide stock therefore trades on more than a simple sales story: the latest annual numbers point to leverage in the operating structure, not just volume growth.

Margin at 27.8%

Air Liquide said its 2025 operating margin reached 27.8%, while recurring net income per share rose 9.9% over the year. The annual report also highlighted 2025 sales of EUR 27.06 billion against EUR 26.39 billion in 2024, a year-on-year increase of roughly EUR 670 million.

For investors, the margin is the key figure because it helps explain why earnings grew faster than sales. A 27.8% operating margin is a strong base for a large industrial gas group, and it gives the stock a valuation anchor even without a fresh trading-day catalyst.

What the annual numbers say

The company said 2025 recurring net profit reached EUR 3.15 billion and recurring net income per share advanced to EUR 5.66 from EUR 5.15 in 2024. Air Liquide also reported a recurring operating margin improvement of 80 basis points in 2025, which supports the view that pricing and productivity remained effective across the year.

Those figures matter because they show the same pattern across three levels: revenue, profit, and per-share earnings all moved higher in 2025. That combination is more informative than a single line item, especially for a stock that often trades on margin durability and capital discipline.

Industrial gases in focus

Air Liquide's industrial gases business remains the representative product set for the group, spanning oxygen, nitrogen, and hydrogen supply to industry and healthcare. In 2025, that portfolio benefited from a business mix that supported recurring profit growth faster than sales growth, which is the part of the story the market usually rewards.

Hydrogen remains especially relevant because it links Air Liquide's core industrial business with energy-transition projects, but the 2025 numbers show that the main earnings engine is still the traditional gas platform. That makes the annual margin and profit profile more important than any single product headline.

Stock level and market readthrough

The current article frame rests on the latest evidenced annual numbers rather than an unverified intraday print, so the market-relevance anchor is the 2025 report itself. With EUR 27.06 billion in sales, EUR 3.15 billion in recurring net profit, and a 27.8% operating margin, Air Liquide stock has a measured, numbers-first setup that investors can compare with future trading updates.

The next decisive read will be whether the company can keep recurring profit growth ahead of sales growth. That is the cleanest takeaway from the 2025 figures, and it is also the most relevant lens for the next reporting step.
