ABOUT YELLOW CAKE

Yellow Cake is a London-quoted company, headquartered in Jersey, which offers exposure to the uranium spot price. This is achieved through its strategy of buying and holding physical triuranium octoxide ("U3O8"). It may also seek to add value through other uranium-related activities. Yellow Cake and its wholly owned subsidiary (together, the "Group") seek to generate returns for shareholders through the appreciation of the value of its holding of U3O8 and its other uranium-related activities in a rising uranium price environment. The business is differentiated from its peers by its ten-year Framework Agreement for the supply of U3O8 with Kazatomprom, the world's largest uranium producer. The Group currently holds 23.11 million pounds of U3O8, all of which is held in storage in Canada and France.
