Other direct cost of revenue includes compensation, insurance, repairs, and ground lease rent and related property tax. 2. Costs to finance the purchase of miners were zero in all periods presented as the miners were paid for with cash from the Company’s cash balance. The seller did not provide any financing, nor did the Company borrow from a third-party to purchase the miners. 3. Power curtailment credits are credited against our power invoices as a result of temporarily pausing our operations to participate in ERCOT’s Demand Response Service Programs. Our fixed-price power purchase contracts enable us to strategically curtail our mining operations and participate in these programs, which significantly lower our cost to mine Bitcoin. These credits are recognized in Power Curtailment Credits on our Consolidated Statement of Operations, outside of cost of revenue. 4. Computed as revenue recognized from Bitcoin mined divided by the quantity of Bitcoin mined during the same period. Cost of Power: The Company defines Cost of Power as the cost of power directly used in the process of mining Bitcoin, less power curtailment credits divided by the kilowatt (“kWh”) hours used. Power is overwhelmingly the largest marginal input cost in mining Bitcoin and a significant contributor to profitability. Miners with a low cost of power will also be able to profitability mine in a wider range of Bitcoin price and hash price scenarios. Cost to Mine: The Company defines Cost to Mine as the direct cost to mine one Bitcoin, excluding Bitcoin miner depreciation, as calculated in the table below. Cost to Mine represents the marginal profitability on operations of a Bitcoin miner. This number is frequently compared to the market price of Bitcoin to determine at what discount to the market price of Bitcoin a miner is earnings net Bitcoin. 2024 2023 2022 Cost of power for self-mining operations $ 149,019 $ 89,134 $ 54,294 Other direct cost of revenue for self-mining operations(1)(2), excluding Bitcoin miner depreciation 40,205 7,463 20,041 Cost of revenue for self-mining operations, excluding Bitcoin miner depreciation 189,224 96,597 74,335 Less: power curtailment credits(3) (33,685) (71,215) (12,004) Cost of revenue for self-mining operations, net of power curtailment credits, excluding Bitcoin miner depreciation 155,539 25,382 62,331 Bitcoin miner depreciation 155,487 216,605 89,424 Cost of revenue for self-mining operations, net of power curtailment credits, including Bitcoin miner depreciation $ 311,026 $ 30,397 $ 30,397 Quantity of Bitcoin mined 4,828 6,626 5,554 Production value of one Bitcoin mined(4) $ 66,488 $ 28,523 $ 28,245 Cost to mine one Bitcoin, excluding Bitcoin miner depreciation $ 32,216 $ 3,831 $ 11,223 Cost to mine one Bitcoin, excluding Bitcoin miner depreciation, as a % of production value of one Bitcoin mined 48.5% 13.4% 39.7% Cost to mine one Bitcoin, including Bitcoin miner depreciation $ 64,421 $ 4,588 $ 5,473 Cost to mine one Bitcoin, including Bitcoin miner depreciation, as a % of production value of one Bitcoin mined 96.9% 16.1% 19.4% Years Ended December 31,

35 Definitions, Terms, and Reconciliations (Unaudited) Hash Cost: The Company defines Hash Cost as Cost of Revenue for self-mining operations, net of Power Curtailment Credits, excluding Bitcoin miner depreciation divided by the average Petahash per second per day (“PH/s/Day”) produced by operations over the relevant period. Hash Cost measures the costs expended for each unit of hash rate online. Hash rate is the product Riot’s self-mining business provides to the Bitcoin network and what Riot gets paid for. Hash cost can be compared to hash price as an estimate of profitability of a mining operation. Hash Price: The Company defines Hash Price as the expected value of 1 Petahash of hashing power per day (“PH/s/Day”). This data is sourced from Luxor’s Hash Price Index. Hash Price is the revenue received by the Company for each unit of hash rate operating during the period. This metric can be compared to Hash Cost as an estimate of profitability of the mining operations. 2024 2023 2022 Cost of revenue for self-mining operations, net of power curtailment credits, excluding Bitcoin miner depreciation $ 155,539 $ 25,382 $ 46,990 divided by Average Petahash per second per day over the period 15,022 6,808 3,286 Hash Cost (PH/s/day) $ 28.3 $ 10.2 $ 3 9 Years Ended December 31,
