Further information in relation to the Director appointment

Zoe Rizzuto

Zoe Rizzuto is an Executive Director at Langham Hall Fund Management (Jersey) Limited. Langham Hall provides administration services to the Group, which will include the services of Ms Rizzuto.  The Board acknowledges the potential impairment of Ms Rizzuto's independence owing to its business relationship with Langham Hall, as outlined in provision 10 of the UK Corporate Governance Code (which the Company elects to comply with insofar as appropriate given the Group's size, business and resources).

The Board nevertheless regards Ms Rizzuto as an independent non-executive director and undertook a rigorous evaluation to reach this conclusion. Ms Rizzuto did not participate in her own assessment.

Ms Rizzuto brings valuable expertise, particularly in governance, compliance, and the Jersey regulatory environment, along with extensive knowledge of asset management and administration. Her insights are expected to enhance Board discussions and provide objective scrutiny and constructive challenge to both management and fellow directors.

In addition, the Group's business relationship with Langham Hall is not considered material. Langham Hall has multiple similar relationships and Ms Rizzuto does not directly benefit from any fees paid by the Group to Langham Hall. No element of her compensation from Langham Hall is tied to her role as a director of Yellow Cake.

Ms Rizzuto will not serve on the Company's audit, remuneration, or nomination committees.

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 (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 21.68 million pounds of U₃O₈, all of which is held in storage in Canada and France.
