Yellow Cake, a specialist company operating in the uranium sector, with a view to holding physical
uranium for the long term, is pleased to announce that following the completion of the upsized
US$140 million share placing on 2 March 2021, it has informed NAC Kazatomprom JSC
(“Kazatomprom”) that it has elected to exercise its full 2021 US$100 million uranium purchase option under its agreement with Kazatomprom (the “Framework Agreement”) and expects to take delivery of the U3O 8 between April and August 2021.

Additionally, Yellow Cake has agreed to purchase a further 440,000 lb of U₃O₈ at a price of $27.34/lb for total consideration of US$12 million.

These uranium purchases will increase Yellow Cake’s U3O 8 holdings from 9.3 million lb to 13.2 million lb.

To the extent that additional uranium can be sourced for value, Yellow Cake intends to continue with further uranium market purchases

Kazatomprom Option

Under its Framework Agreement with Kazatomprom, Yellow Cake has the option to purchase up to
US$100 million of U3O 8 per year from Kazatomprom at an undisturbed spot price, through to 2027.

Yellow Cake has now fully exercised its 2021 option to purchase US$100 million of U 3O 8 from
Kazatomprom under the Framework Agreement at a price of US$28.95/lb.

The purchase price was agreed on 19 February 2021 (using spot market indicators), enabling the
Company to subsequently complete its U$140 million share placing and then exercise the option at
the agreed price under the Framework Agreement.

This represents 3.5 million lb of additional U 3O 8 which will be delivered into storage as part of Yellow Cake’s long term buy and hold strategy.

This material will be delivered to Cameco’s Port Hope / Blind River facility in Ontario, Canada.
delivery schedule between April and August 2021 will be agreed between the parties.

Additional Uranium Purchased

In addition to fully exercising the 2021 Kazatomprom purchase option, Yellow Cake has agreed to
purchase a further 440,000 lb of U3O 8 at a price of US$27.34/lb and will take delivery of the additional U₃O₈ at Cameco’s Port Hope / Blind River facility during March 2021. This removes material from the already tightening spot market.

“We believe there is a clear shift in sentiment around the outlook for uranium. Significant investor
demand enabled us to considerably increase the size of the share placing. We now see real opportunity for shareholders to benefit from the pending rebalancing of the uranium market. The larger placing also provides strategic benefits to Yellow Cake. We can now fully exercise the Kazatomprom option for 2021, and also actively look for further selective market opportunities to increase our exposure to the uranium price.”

– Andre Liebenberg, CEO of Yellow Cake

ABOUT YELLOW CAKE
Yellow Cake is a London-listed company founded and established by Bacchus Capital and
headquartered in Jersey, which offers exposure to the uranium spot price. This is achieved through its strategy of buying and holding physical triuranium octoxide (“U 3O 8”). It may also seek to add value through the acquisition of uranium royalties and streams or other uranium related activities. Yellow Cake seeks 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. Yellow Cake currently holds 9.32 million lb of U₃O₈, all of which is held in storage in Canada and France.
