Statements in this presentation that are not statements of historical fact are forward-looking statements that reflect management’s current expectations, assumptions, and estimates of future performance and economic conditions, and are not guarantees of future performance or actual results. Such statements are made in reliance on the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements may include, but are not limited to, statements about the benefits of acquisitions, including potential future financial and operating results, as well as the Company’s plans, objectives, expectations, and intentions. Words such as “anticipates,” “believes,” “plans,” “expects,” “intends,” “will,” “potential,” “hope,” and similar expressions are intended to identify forward-looking statements; however, forward-looking statements may be made without such signifying expressions.

These risks and uncertainties include, but are not limited to: unaudited estimates of Bitcoin production; our future hash rate growth (EH/s); the anticipated benefits, construction schedule, and costs associated with the Corsicana Facility; our expected schedule of new miner deliveries; our ability to successfully deploy new miners; MW capacity under development; risks related to our realization of the benefits we anticipate from immersion-cooling; risks related to the success, schedule, cost and difficulty of integrating businesses we acquire; our failure to realize anticipated efficiencies and strategic and financial benefits from our acquisitions; and the impact that COVID-19 and other global events may have on us, our customers, our suppliers, and on economic conditions in connection with our estimated timelines, future performance and operations. Detailed information regarding the factors identified by the Company’s management which they believe may cause actual results to differ materially from those expressed or implied by the forward-looking statements contained in this presentation may be found in the Company’s filings with the U.S. Securities and Exchange Commission (the “SEC”), including the risks, uncertainties and other factors discussed under the sections entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as amended, and the other filings the Company makes with the SEC, copies of which may be obtained from the SEC’s website, www.sec.gov.

18 Definitions, Terms, and Reconciliations (Unaudited) 1. 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 2024 2023 Cost of power for self-mining operations $ 41,864 $ 22,460 $ 96,326 $ 65,513 Other direct cost of revenue for self-mining operations(1)(2), excluding Bitcoin miner depreciation 9,608 1,989 26,970 4,482 Cost of revenue for self-mining operations, excluding Bitcoin miner depreciation 51,472 24,449 123,296 69,995 Less: power curtailment credits(3) (12,417) (49,601) (31,445) (66,146) Cost of revenue for self-mining operations, net of power curtailment credits, excluding Bitcoin miner depreciation 39,055 (25,152) 91,851 3,849 Bitcoin miner depreciation 44,303 55,549 93,120 164,457 Cost of revenue for self-mining operations, net of power curtailment credits, including Bitcoin miner depreciation $ 83,358 $ 30,397 $ 184,971 $ 168,306 Quantity of Bitcoin mined 1,104 1,106 3,312 4,996 Production value of one Bitcoin mined(4) $ 61,133 $ 28,228 $ 58,771 $ 25,818 Cost to mine one Bitcoin, excluding Bitcoin miner depreciation $ 35,376 $ (22,741) $ 27,733 $ 770 Cost to mine one Bitcoin, excluding Bitcoin miner depreciation, as a % of production value of one Bitcoin mined 57.9% -80.6% 47.2% 3.0% Cost to mine one Bitcoin, including Bitcoin miner depreciation $ 75,506 $ 27,484 $ 55,849 $ 33,688 Cost to mine one Bitcoin, including Bitcoin miner depreciation, as a % of production value of one Bitcoin mined 123.5% 97.4% 95.0% 130.5% Three Months Ended Nine Months Ended September 30, September 30, 2024 2023 2024 2023 Total Cost of Power $ 50,620 $ 35,241 $ 121,823 $ 101,550 less Power curtailment credits (12,417) (49,601) (31,100) (63,922) Net Cost of Power $ 38,203 $ (14,360) $ 90,723 $ 37,628 kWh used 1,233,531,741 769,518,913 2,862,705,794 2,276,097,806 Cost of Power (c/kWh) $ 3.1 $ (1.9) $ 3.2 $ 1.7 Three Months Ended Nine Months Ended September 30, September 30,

Fully Costed Gross Margin: The Company defines Fully Costed Gross Margin as Fully Costed Gross Profit (as defined below) divided by Revenue as calculated below. Fully Costed Gross Profit: The Company defines Fully Costed Gross Profit as Revenue less Cost of Revenue less Depreciation and Amortization expense as calculated below. 19 Definitions, Terms, and Reconciliations (Unaudited)

20 Definitions, Terms, and Reconciliations (Unaudited) Cash SG&A: The Company defines Cash SG&A as Selling, General, and Administrative expenses less Stock-Based Compensation expense. Cash SG&A is used by the Company as we believe it better reflects the operational requirements of the Company by excluding significant non-cash items such as stock-based compensation expense. EPS (Earnings per Share): The Company defines EPS as Diluted Net Income (Loss) per Share. Gross Margin: The Company defines Gross Margin as Gross Profit (as defined below) divided by Revenue. Gross Margin represents the percentage of profit achieved by operations and is a measure of the level of profitability for direct costs and the revenue received from them. 2024 2023 2024 2023 Selling, general, and administrative $ 66,936 $ 29,067 $ 185,777 $ 61,578 less Stock-based compensation expense (30,567) (13,519) (94,702) (14,652) Cash SG&A $ 36,369 $ 15,548 $ 91,075 $ 46,926 Three Months Ended Nine Months Ended September 30, September 30,

21 Definitions, Terms, and Reconciliations (Unaudited) Gross Profit: The Company defines Gross Profit as Fully Costed Gross Profit (as defined below) plus Power curtailment Credits plus Depreciation & Amortization expense. M&A Expenses: The Company defines M&A Expenses as Acquisition-related costs.

22 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.
