Air Liquide is the 2nd largest gas company in Europe. Air Liquide operations consist, among other things, of manufacturing and selling gases to areas such as industry, chemistry, electronics, food, environmental care and healthcare. The company operates on a global level. Air Liquide was founded in 1902 and has its headquarters in Paris

Europe needs to switch from Russian Gas to other suppliers and that will be beneficial for Air Liquide.
If you look at the que figures, the revenue is increasing, and they also have a good cashflow.
Since start, Air Liquide has increased its turnover and is still growing. So I see no problem with the P/E being just over 28.
