**Riot Platforms Reports Second Quarter 2025 Financial Results, Current Operational and Financial Highlights** 

Riot Reports $219.5 million in Net Income and $495.3 million in Adjusted EBITDA

CASTLE ROCK, Colo., July 31, 2025 (GLOBE NEWSWIRE) -- **Riot Platforms, Inc. (NASDAQ: RIOT) ("Riot" or "the Company")**, a Bitcoin-driven industry leader in the development of large-scale data centers for high performance computing and bitcoin mining applications, reported financial results for the three-month period ended June 30, 2025. The accompanying presentation materials are available on Riot's website.

"I am pleased to announce Riot's results for the second quarter of 2025," said Jason Les, CEO of Riot. "Strong tailwinds in the price of bitcoin contributed to Riot achieving a record $219.5 million in net income and $495.3 million in adjusted EBITDA, representing exceptionally strong results for the quarter.

"We are immensely proud of our evolution over the past several years, having built world-class capabilities in power procurement, Bitcoin mining at global scale, and infrastructure engineering, culminating in a strong position to control our destiny and maximize shareholder value. Our strategy centers on optimizing our ready-for-service power portfolio – anchored by flagship sites in Rockdale and Corsicana – while progressively shifting capacity toward high-value data centers, bolstered by our addition of hyperscale expertise through recent hires, in particular Jonathan Gibbs as Chief Data Center Officer. With a robust balance sheet, battle-hardened teams, and significant access to capital markets, we are uniquely positioned at the intersection of surging high performance computing demand and Bitcoin growth to maximize utilization of our significant power capacity, expand thoughtfully, and drive compelling long-term value for our shareholders."

**Second Quarter 2025 Financial and Operational Highlights**

Key financial and operational highlights for the second quarter include:

● Total revenue of $153.0 million, as compared to $70.0 million for the same three-month period in 2024. The increase was primarily driven by a $85.1 million increase in Bitcoin Mining revenue.

● Produced 1,426 bitcoin, as compared to 844 during the same three-month period in 2024.

● The average cost to mine bitcoin, excluding depreciation, was $48,992 in the quarter, as compared to $25,329 per bitcoin in the same three-month period in 2024. The increase was primarily driven by the block subsidy 'halving' event, which occurred in April 2024, and a 45% increase in the average global network hash rate as compared to the same period in 2024.

● Bitcoin Mining revenue of $140.9 million for the quarter, as compared to $55.8 million for the same three-month period in 2024, primarily driven by higher average bitcoin prices and an increase in operational hash rate, partially offset by the block subsidy 'halving' event and an increase in the average global network hash rate.

● Engineering revenue of $10.6 million for the quarter, as compared to $9.6 million for the same three-month period in 2024. Riot has benefited from $18.5 million in capex savings alone since the acquisition of ESS Metron in December 2021, representing a key advantage of the Company's vertical integration strategy.

------

● Maintained industry-leading financial position, with $141.1 million in working capital, including $255.4 million in unrestricted cash on hand, $74.9 million in restricted cash, and $62.5 million in marketable equity securities.

● Held 19,273 bitcoin (of which 3,300 is currently held as collateral), equating to approximately $2.1 billion based on a market price for one bitcoin on June 30, 2025, of $107,174.

**Non-U.S. GAAP Measures of Financial Performance**

In addition to financial measures presented under generally accepted accounting principles in the United States of America ("GAAP"), we consistently evaluate our use of and calculation of non-GAAP financial measures such as "Adjusted EBITDA." EBITDA is computed as net income before interest, taxes, depreciation, and amortization. Adjusted EBITDA is a performance measure defined as EBITDA, adjusted to eliminate the effects of certain non-cash and/or non-recurring items that do not reflect our ongoing strategic business operations, which management believes results in a performance measurement that represents a key indicator of the Company's core business operations of Bitcoin mining. The adjustments include fair value adjustments such as derivative power contract adjustments, equity securities value changes, and non-cash stock-based compensation expense, in addition to financing and legacy business income and expense items. We exclude impairments and gains or losses on sales or exchanges of Bitcoin from our calculation of Adjusted EBITDA for all periods presented.

We believe Adjusted EBITDA can be an important financial measure because it allows management, investors, and our board of directors to evaluate and compare our operating results, including our return on capital and operating efficiency from period-to-period by making such adjustments. Additionally, Adjusted EBITDA is used as a performance metric for share-based compensation.

Adjusted EBITDA is provided in addition to, and should not be considered to be a substitute for, or superior to, net income, the most comparable measure under GAAP for Adjusted EBITDA. Further, Adjusted EBITDA should not be considered as an alternative to revenue growth, net income, diluted earnings per share or any other performance measure derived in accordance with GAAP, or as an alternative to cash flow from operating activities as a measure of our liquidity. Adjusted EBITDA has limitations as an analytical tool, and you should not consider such measures either in isolation or as substitutes for analyzing our results as reported under GAAP.

------

The following table reconciles Adjusted EBITDA to Net income (loss), the most comparable GAAP financial measure:

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 earning bitcoin. 2025 2024 2025 2024 Cost of power for self-mining operations $62,170 $26,465 $123,999 $54,463 Other direct cost of revenue for self-mining operations(1)(2), excluding Bitcoin miner depreciation 16,005 8,810 28,994 17,361 Cost of revenue for self-mining operations, excluding Bitcoin miner depreciation 78,175 35,275 152,993 71,824 Less: power curtailment credits(3) (8313) (13897) (16114) (19028) Cost of revenue for self-mining operations, net of power curtailment credits, excluding Bitcoin miner depreciation 69,862 21,378 136,879 52,796 Bitcoin miner depreciation 60,252 26,377 117,314 48,816 Cost of revenue for self-mining operations, net of power curtailment credits, including Bitcoin miner depreciation $130,114 $47,755 $254,193 $101,612 Quantity of Bitcoin mined 1,426 844 2,956 2,208 Production value of one Bitcoin mined(4) $98,800 $66,069 $95,991 $57,591 Cost to mine one Bitcoin, excluding Bitcoin miner depreciation $48,992 $25,329 $46,305 $23,911 Cost to mine one Bitcoin, excluding Bitcoin miner depreciation, as a % of production value of one Bitcoin mined 49.6% 38.3% 48.2% 41.5% Cost to mine one Bitcoin, including Bitcoin miner depreciation $91,244 $56,582 $85,992 $46,020 Cost to mine one Bitcoin, including Bitcoin miner depreciation, as a % of production value of one Bitcoin mined 92.4% 85.6% 89.6% 79.9% Six Months Ended June 30, Three Months Ended June 30, 2025 2024 2025 2024 Total Cost of Power $62,170 $26,465 $123,999 $54,463 less Power curtailment credits (8313) (13897) (16114) (19028) Net Cost of Power $53,857 $12,568 $107,885 $35,435 kWh used 1,538,273,540 603,821,698 2,990,774,540 1,162,800,658 Cost of Power (c/kWh) $3.5 $2.1 $3.6 $3.0 Three Months Ended June 30, Six Months Ended June 30, |
