Monthly Investor Update 5 Assumptions and Notes 1. Bitcoin and Bitcoin mined in this investor update are presented in accordance with our revenue recognition policy which is determined on a Bitcoin received basis (post deduction of mining pool fees). 2. Comprises actual power usage for Canal Flats, Mackenzie, Prince George, and Childress. The Company’s Canal Flats, Mackenzie and Prince George sites have been powered by 100% renewable energy since inception of which approximately 98% is directly from renewable energy sources; approximately 2% is from the purchase of RECs. The Company’s Childress site has been powered by 100% renewable energy since inception via the purchase of RECs. 3. Electricity costs presented on a net basis and calculated as IFRS electricity charges net of realized gain/(loss) on financial asset, ERS revenue (included in other income) and ERS fees (included in other operating expenses). Figures are based on current internal estimates and exclude REC purchases. 4. Hardware profit margin for Bitcoin mining and AI Cloud Services is calculated as revenue less net electricity costs, divided by revenue (for each respective revenue stream) and excludes all other costs. 5. Capacity to be installed comprises Bitmain T21 and S21 Pro miner purchases and miner purchase options. Additional S21 Pro miners secured will also be used to upgrade the existing fleet. Final decisions with respect to exercising miner purchase options will be made during 2024 taking into consideration market and funding conditions.
