Air Water Inc. (4088.T) : juste valeur

Thèse ACCE

Air Water makes industrial gases (oxygen, nitrogen, hydrogen) and the equipment and medical supply businesses built around them, serving steel, electronics, chemicals and hospitals across Japan and Asia. The structural case rests on long-term supply contracts with on-site gas plants, which lock in customers for years and make the revenue stream more durable than the headline commodity-chemical label suggests. Reported revenue grew 30.2%, which is large enough to ask whether it reflects acquisitions, pass-through energy costs or real volume gains, and that is the first question to settle before anything else. Trading at 15.1 times trailing earnings and 12.2 times forward, the stock screens cheaply against a group that typically carries a premium for contracted gas franchises, but the 6.2% operating margin and a negative 15.3% ROE mean the balance sheet and write-downs need a closer read. Worth a deeper look to test whether the growth is organic and whether the forward earnings estimates hold up.
