Demand for uranium is rising as Japan restarts its nuclear reactors and U.S. utilities step up their purchases, said Amir Adnani, CEO of Uranium Energy Corp. Adnani added that uranium prices, now around $40, could rise as high as $50 by the end of 2015. He said China will be a big buyer considering that it is building nearly 30 new nuclear plants. Adnani said concern over carbon emissions and climate change are causing renewed momentum in nuclear energy. Finally, Adnani said Uranium Energy Corp. is a low cost provider that does not hedge so it will have a big market opportunity as the price rises.
