welcome several new Directors to the Company&#x2019;s Board,

David&#x2019;s leadership, the Company has executed on its strategic
plan to divest its non-core international assets and position
itself as the leading junior developer in the eastern Athabasca
Basin. Denison is the Lundin Group of Companies&#x2019; flagship
uranium investment, and we are expecting tremendous growth ahead in
this sector &#x2013; especially now that we are seeing significant
supply cuts from the largest uranium producers, which should
fundamentally improve the oversupply situation that has plagued the
commodity for the last several years.</font></font></div>
