Monthly Investor Update 5 Assumptions and Notes 1. Refers to Illustrative Annualized Hardware Profit, as defined in footnote 6 below. See Forward-Looking Statements disclaimer below, including Non-IFRS Financial Measures. 2. 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). 3. 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. 4. Electricity costs are presented on a net basis and calculated as IFRS electricity charges net of realized gain/(loss) on financial assets (excluding one-off cost of $7.2m to close out August and September 2024 power hedges, as part of the transition to spot pricing), 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. 5. 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. 6. Illustrative Annualized Hardware Profit = illustrative revenue less assumed electricity costs (excludes all other site, overhead and Renewable Energy Certificate (“REC”) costs). Calculations assume hardware operates at 100% uptime. AI Cloud Services calculations assume 1.25kW power draw per GPU, $0.045/kWh electricity costs and lower end of a $2.00 - $2.50 per GPU hour revenue assumption range. Bitcoin mining calculations assume $60,000 (Bitcoin price), 633 EH/s (global hashrate), 3.125 BTC (block reward), 0.1 BTC (transaction fees), 0.15% (pool fees), 484MW (power consumption), $0.038/kWh electricity costs (4.5c/kWh BC, 3.5c/kWh Childress). 7. Capacity to be installed comprises combination of Bitmain T21, S21 Pro and S21 XP miners.
