This company can be really very big provided the management remain hungry & aggressive while with prudent capital allocations, and more importantly with good corporate governance. They are in the right business with right products with good technology. Hydrogen is a big upcoming opportunity. Wish they continue to invest in strong R&D capabilities and innovation, new product development & patents. Hope they will be able to deliver superior growth and profits and create wealth for its shareholder. I wish all the best to the management..
