Exhibit 99.1

Riot Platforms Reports Second Quarter 2026 Financial Results and Strategic Highlights

Executed 20-year data center lease with a leading frontier AI lab for 191 MW of critical IT capacity at Riot’s Rockdale campus, expected to generate approximately $9.1 billion in total contract revenue over the initial term

Completed delivery of the initial 25 critical IT MW to AMD on time and on budget, with the second 25 critical IT MW expansion under construction

Together with the AMD lease, the Company has contracted 241 MW of critical IT capacity with two of the most significant companies in the AI ecosystem

Quarterly revenue of $174.2 million, a 14% increase year-over-year, including $23.2 million in Data Center revenue

CASTLE ROCK, Colo., August 10, 2026 (GLOBE NEWSWIRE) — Riot Platforms, Inc. (NASDAQ: RIOT) (“Riot” or “the Company”), a vertically-integrated industry leader in digital infrastructure, specializing in the development of large-scale data centers and bitcoin mining applications, reported financial results for the three-month period ended June 30, 2026. The accompanying presentation materials are available on Riot’s website.

“Today's announcement of a landmark 20-year, 191-megawatt data center lease with a leading frontier AI lab marks a defining moment in our evolution into a leading developer of large-scale data centers,” said Jason Les, CEO of Riot. “It builds directly on a strong second quarter, in which we completed delivery of the initial 25 megawatts to AMD on time and on budget. In just over six months, Riot has now executed leases totaling 241 megawatts of capacity, representing approximately $9.8 billion of long-term, contracted revenue with two of the most important companies in the AI ecosystem.

“Our platform stands apart through three elements working together: multi-gigawatt-scale power capacity that is already fully approved and energized, in-house data center development expertise, and the ability to engineer custom infrastructure for computing's most demanding workloads. With all three, and the financial resources to deploy them already secured, we are positioned to convert strong market demand from high-quality tenants into compounding shareholder value.”

191 IT MW Data Center Lease with a Leading Frontier AI Lab at Rockdale

Subsequent to quarter end, Riot announced the execution of a Data Center Lease and Services Agreement (the “Data Center Lease”) with one of the world’s leading frontier AI labs, for 191 MW of critical IT capacity at Riot’s Rockdale campus. The Data Center Lease carries an initial term of 20 years, running through June 2048, and is expected to generate approximately $9.1 billion in total initial contract revenue. The Data Center Lease also includes two five-year extension options at the tenant’s election, representing a total potential contract value of approximately $16.1 billion if both extensions are fully exercised.

This transaction secures the Company’s second tenant at the Rockdale campus, following the lease with Advanced Micro Devices, Inc. (“AMD”) announced on January 16, 2026. Together, the two agreements firmly establish Riot as a leading contracted AI data center developer.

Transaction highlights:

• Capacity Leased: 191 MW critical IT build-to-suit Tier 3 data center at Riot’s Rockdale campus.

• Total Contract Value: $9.1 billion over the initial 20-year term, with a total potential contract value of approximately $16.1 billion if both five-year extension options are exercised.

• NOI Contribution: Estimated cumulative NOI range of $7.3 to $8.2 billion over the base lease term, with an estimated average annual NOI contribution of $365 to $411 million.

• Delivery Schedule: Phased delivery schedule, with the initial 96 IT MW expected in December 2027 and full 191 IT MW deployment expected by June 2028, leveraging Riot’s existing, fully approved interconnection at the Rockdale campus.

• Financing: $573 million interim financing facility provided by Morgan Stanley to fund initial development costs while the investment-grade credit backstop is finalized.

Second Quarter 2026 Financial and Operational Highlights

Key financial and operational highlights for the quarter include:

• Total revenue of $174.2 million, as compared to $153.0 million for the same three-month period in 2025, a 14% increase year-over-year.

• Data Center revenue of $23.2 million for the quarter, comprised of $4.9 million in operating lease revenue and $18.3 million in tenant fit-out services revenue, reflecting the Company’s second quarter of Data Center segment revenue and the completed delivery of the initial 25 MW to AMD.

• Produced 1,587 bitcoin, as compared to 1,426 during the same three-month period in 2025.

• The average cost to mine bitcoin, excluding depreciation, was $49,912 in the quarter, as compared to $48,992 per bitcoin in the same three-month period in 2025. The increase was primarily driven by higher power costs and the expansion at Riot’s Kentucky facilities.

• Bitcoin Mining revenue of $113.7 million for the quarter, as compared to $140.9 million for the same three-month period in 2025, primarily driven by lower average bitcoin prices and an increase in global network hash rate, partially offset by an increase in Riot’s average operating hash rate.

• Engineering revenue of $37.3 million for the quarter, as compared to $10.6 million for the same three-month period in 2025.

• Ended the quarter with over $1.2 billion in liquid assets, including 11,380 bitcoin (of which 5,821 were held as collateral), equating to approximately $666.0 million based on the market price for one bitcoin on June 30, 2026 of $58,527, and $548.9 million in cash (of which $77.5 million is restricted).

AMD Deployment Progress at Rockdale

During the quarter, Riot completed delivery of the final 20 MW of AMD’s initial deployment, bringing the full 25 MW of commissioned capacity online, on time and on budget, and converting the lease to recurring revenue at full initial scale. Construction is now underway on the 25 MW expansion, with the 10 MW Phase 3 on track for delivery in November 2026 and the 15 MW Phase 4 to follow in May 2027, at which point AMD's total contracted capacity of 50 MW will be fully deployed. Riot’s in-house procurement, engineering and construction capabilities continue to underpin this delivery record.

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 financial 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 fair value changes, and non-cash stock-based compensation expense, in addition to financing and legacy business income and expense items. We believe Adjusted EBITDA can be an important financial performance 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 efficiencies 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 a substitute for, or superior to, net income, the most comparable measure under GAAP to Adjusted EBITDA. Further, Adjusted EBITDA should not be considered as an alternative to revenue growth, net income, diluted net income 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 this financial measure either in isolation or as a substitute for analyzing our results as reported under GAAP.

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

For the three months ended June 30, 2026 and 2025, we paid cash of $25.2 million and $71.3 million, respectively, and for the six months ended June 30, 2026 and 2025, we paid cash of $48.7 million and $92.3 million, respectively, in total deposits and payments for the purchase of miners. 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 Condensed Consolidated Statements of Operations, outside of cost of revenue, but significantly reduce our overall cost to mine bitcoin.

(4)

We capitalize the acquisition cost of our miners and include these costs in Property and equipment, net on our Condensed Consolidated Balance Sheets. The miners are depreciated over an estimated useful life of three years, during which time, they are expected to contribute to the generation of bitcoin revenue. We do not consider depreciation expense in determining whether it is economical to operate our miners because depreciation is a non-cash expense and is not a variable operating cost that can be avoided even if we curtail operations temporarily. Depreciation expense incurred is disclosed for each respective period in the table above.

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.
