Each Uranerz shareholder received 0.255 Energy Fuels common shares for each share of common stock held.
Dennis Higgs, the former executive chairman and a director of Uranerz, and Glenn Catchpole, the former chief executive officer and a director of Uranerz, were appointed as directors of Energy Fuels.
The Uranerz Group was the world’s third largest uranium producer when it was purchased in 1998 by Cameco.
Energy Fuels president and CEO Stephen Antony said: "With the completion of our acquisition of Uranerz, Energy Fuels is clearly emerging as a leading integrated producer of uranium in the U.S."
"We now have competitive ISR and conventional uranium production in our portfolio, the largest NI 43-101 compliant in-ground uranium resource in the U.S. among producers, and the ability to significantly increase uranium production in the future as uranium prices rise."
Energy Fuels supplies U3O8 to major nuclear utilities in the US and globally.
The company operates two uranium production centers in the US, which include the White Mesa Mill in Utah and the Nichols Ranch Processing Facility in Wyoming.
