Boss Energy (BOE) investor relations material

Strategic positioning and operational overview

• Operates as a multi-mine uranium producer with assets in Australia and the US, leveraging ISR expertise and technology for operational efficiency.

• Maintains a strong balance sheet with $208M in cash and liquid assets, including a strategic uranium inventory.

• Focuses on optimizing the Honeymoon operation, unlocking value from satellite deposits, and maximizing the Alta Mesa JV.

• Accelerated development of satellite deposits Gould's Dam and Jason's Deposit, with significant resource updates and permitting progress.

• Clear pathway to drive shareholder value through disciplined capital management and operational improvements.

Technical innovation and project development

• Wide-spaced wellfield design under study aims to reduce costs, lower cutoff grades, and increase resource under leach.

• Advanced reactive transport simulations are being used to optimize wellfield design and predict fluid and geochemical behavior.

• Technical studies validate assumptions about Honeymoon deposit, supporting lower-grade mining and cost structure changes.

• Modifications to wellfield designs at Honeymoon and East Kalkaroo aim to accelerate production and improve economics.

• Satellite deposits benefit from the same wide-spaced wellfield approach, potentially increasing resource conversion to mine plans.

Production and financial performance

• Q3FY26 production at Honeymoon expected to be lower (240-270klbs) due to rain, with record production (490-520klbs) targeted for Q4FY26 as more wellfields come online.

• Strong financial position with $208M in cash and liquid assets, and 1.6Mlbs uranium inventory for future value.

• Cash flow supports ongoing operations and transition to wide-spaced wellfield design.

• No ongoing cost from FY27 for Alta Mesa JV inventory, with all inventory accumulated and no sales executed.

• Delivery of the New Feasibility Study is scheduled for Q3CY26, expected to clarify future capital and operating costs.
