NOTE 11 – COMMITMENTS AND CONTINGENCIES

Dependence on Third Parties

Sales during 2023 to the Company’s top three customers was approximately 22% of its total gross revenue. The Company is making efforts to reduce its dependency on a small number of customers by expanding both domestic and foreign.

The production of Cobalt is dependent upon the DOE, and its prime operating contractor, which controls the reactor and laboratory operations at the ATR located outside of Idaho Falls, Idaho.

However, the DOE may end the contract if it determines termination is necessary for the national defense, security or environmental safety of the U.S. If this were to occur, all payments made by the Company would be refunded.

The key isotope materials used to manufacture our radiopharmaceutical product and nuclear medicine reference standards are supplied to the Company through agreements with several suppliers. The loss of any of these suppliers could adversely affect operating results by causing a delay in production or a possible loss of sales.

Contingencies

Because all the Company’s business segments involve the handling or use of radioactive material, the Company is required to have an operating license from the NRC and specially trained staff to handle these materials.
