CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (the “Quarterly Report”) contains forward-looking statements. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements contained in this Quarterly Report, other than statements of historical fact, including, without limitation, statements about our beliefs and expectations regarding our future results of operations and financial position, planned business model and strategy, our bitcoin mining and high-performance compute (“HPC”) data center development, timing and likelihood of success, capacity, functionality and timing of operation of data centers, expectations regarding the operation of data centers, potential strategic initiatives, such as joint ventures and partnerships, and management plans and objectives are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “seeks,” “intends,” “targets,” “projects,” “contemplates,” “believes,” “estimates,” “forecasts,” “predicts,” “potential” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements use these words or expressions. The forward-looking statements in this Quarterly Report are only predictions and are largely based on our current expectations and projections about future events and trends that we believe may affect our business, financial condition and results of operations. Forward-looking statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, the following:

•We operate in a rapidly evolving industry and have an evolving business model and strategy, which includes our increasing focus on diversification into constructing and operating data centers for HPC companies, as well as bitcoin mining.

•If we fail to grow our hashrate, we may be unable to compete, and our results of operations could suffer.

•The further development and acceptance of digital asset networks and other digital assets, which represent a new and rapidly changing industry, are subject to a variety of factors that are difficult to evaluate. The slowing or stopping of the development or acceptance of digital asset systems may adversely affect an investment in us.

•We may face several risks due to disruptions in the digital asset markets, including but not limited to, financing risk, risk of increased losses or impairments in our investments or other assets, risks of legal proceedings and government investigations, and risks from price declines or price volatility of digital assets.

•Any unfavorable global economic, business or political conditions, such as geopolitical tensions, military conflicts, acts of terrorism, natural disasters, pandemics, trade restrictions, tariffs, or similar events could adversely affect our business, financial condition and results of operations.

•Bitcoin mining activities are energy-intensive, which may restrict the geographic locations of miners and have a negative environmental impact. Government regulators may potentially restrict the ability of electricity suppliers to provide electricity to mining operations, such as ours, increase taxes on the purchase of electricity used to mine bitcoin, or even fully or partially ban mining operations.

•We have concentrated our operations and, thus, are particularly exposed to the performance of the Odessa Facility and changes in the regulatory environment, market conditions and natural disasters in Texas.

•We depend on third parties, including electric grid operators, electric utility providers and manufacturers of certain critical and specialized equipment, and rely on components and raw materials that may be subject to price fluctuations or shortages, including application-specific integrated circuit (“ASIC”) chips that have been subject to periods of significant shortage and high innovation pace.

•We may be affected by price fluctuations in the wholesale and retail power markets.

•We are vulnerable to severe weather conditions and natural disasters, including severe heat, winter weather events, earthquakes, fires, floods, hurricanes, as well as power outages and other industrial incidents or mechanical failures, which could severely disrupt the normal operation of our business and adversely affect our results of operations.

•Bitcoin miners and other necessary hardware are subject to malfunction, technological obsolescence and physical degradation.

•If we or our third-party providers fail to protect confidential information and/or experience cybersecurity incidents, such as cyber-attacks, data breaches, hacking attacks or malware, there may be disruptions to our operations, triggering significant liability for us, which could harm our operating results and financial condition, and damage our reputation or otherwise materially harm our business.

•The value of bitcoin has historically been subject to wide swings, and our operating results may be adversely affected by our hedging activity.

•There is a potential that, in the event of a bankruptcy filing by a custodian, bitcoin held in custody could be determined to be property of a bankruptcy estate and we could be considered a general unsecured creditor thereof.

•Regulatory changes or actions may restrict the use of bitcoin in a manner that adversely affects our business, prospects or operations.

•Our sources of revenue are dependent on bitcoin and the Bitcoin ecosystem, which can be highly volatile.

•Any potential use of emerging technologies like artificial intelligence, machine learning and generative artificial intelligence could lead to unintended consequences and result in reputational harm and litigation.

•We have identified a material weakness in our internal control over financial reporting which, if not timely remediated, may adversely affect the accuracy and reliability of our future financial statements, and our reputation, business and the price of our common stock, as well as may lead to a loss of investor confidence in us.

•The important factors discussed in Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the Securities and Exchange Commission (the “SEC”) on February 25, 2025 (the “2024 Form 10-K”), and our other reports filed with the SEC.

The forward-looking statements in this Quarterly Report are based upon information available to us as of the date of this Quarterly Report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

You should read this Quarterly Report and the documents that we reference in this Quarterly Report and have filed as exhibits to this Quarterly Report with the understanding that our actual future results, performance and achievements may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements. These forward-looking statements speak only as of the date of this Quarterly Report. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained in this Quarterly Report, whether as a result of any new information, future events or otherwise.

NOTE 1. ORGANIZATION

Nature of operations

Cipher Mining Inc. (“Cipher” or the “Company”) is focused on the development and operation of industrial-scale data centers for bitcoin mining and high-performance compute (“HPC”) hosting. The Company operates two wholly-owned bitcoin mining data centers, a 207 MW site located in Odessa, Texas that draws fixed priced power from a power purchase agreement with its electricity provider (the “Odessa Facility”), and a 300 MW data center in Wink, Texas that draws power from the power grid (the “Black Pearl Facility”) and has equity investments in three partially-owned joint venture bitcoin mining data centers. The Company’s portfolio as of June 30, 2025 also includes three wholly-owned sites which have not commenced operations, and options to acquire three additional wholly-owned sites.

Risks and uncertainties

Liquidity and capital resources

The Company has historically experienced net losses and negative cash flows from operations; however, proceeds from sales of bitcoin are categorized as cash flows from investing activities to the extent bitcoin is sold after seven days of receipt. As of June 30, 2025, the Company had approximate balances of cash and cash equivalents of $62.7 million, working capital of $167.2 million, total stockholders’ equity of $748.9 million and an accumulated deficit of $266.2 million. The Company uses a combination of proceeds from sales of bitcoin earned by or received from its bitcoin mining data centers, short-term and long-term financing arrangements, and strategic sales of shares through “at-the-market” offerings to support its operating expenses and capital expenditures.

The Company monitors its balance sheet on an ongoing basis to determine the proper mix of bitcoin retention and bitcoin sales to support its cash requirements, ongoing operations, and capital expenditures. Bitcoin is classified as a current asset on the Company’s balance sheets due to its intent and ability to sell bitcoin to support operations when needed. Approximately $103.5 million of cash was used for operating activities during the six months ended June 30, 2025.

During the six months ended June 30, 2025, the Company sold bitcoin for proceeds of approximately $121.4 million, paid approximately $162.4 million for deposits on equipment primarily related to new miner purchases, and paid approximately $55.9 million for property and equipment primarily related to the build-out of the Black Pearl Facility.

The Company has a master loan agreement with Coinbase Credit, Inc., as Lender, and Coinbase, Inc., as Lending Service Provider (the “Coinbase Master Loan Agreement”). Pursuant to the master loan agreement, the Company has a secured line of credit up to $25.0 million (the “Coinbase Overnight Credit Facility”), and a term loan facility with Coinbase with a limit of $35.0 million and maximum period of one year (the “Term Loan Facility”). As described in more detail in Note 14. Debt, the borrowings are collateralized by bitcoin transferred to the Lending Service Provider’s platform.

On May 22, 2025, the Company issued $172.5 million principal amount of convertible notes due in 2030 with an interest rate of 1.75% (the “2030 Convertible Notes”). The 2030 Convertible Notes are senior, unsecured obligations with interest due semiannually on May 15 and November 15 each year beginning on November 15, 2025. Refer to Note 14. Debt for more details.

Management believes that the Company’s existing financial resources, combined with projected cash and bitcoin inflows from its data centers, its ability to sell bitcoin received or earned, and its intent and ability to sell common stock through at-the-market offerings will be sufficient to enable the Company to meet its operating and capital requirements for at least 12 months from the date these condensed consolidated financial statements are issued.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation and principles of consolidation

The Company prepares its unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the U.S. (“GAAP”) as determined by the FASB and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (“SEC”).

The unaudited condensed consolidated financial statements include the accounts of the Company and its controlled subsidiaries. All intercompany transactions and balances have been eliminated.

CIPHER MINING INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Certain prior year amounts have been reclassified for consistency with the current period presentation. Effective for the year ended December 31, 2024, the Company changed the presentation of its consolidated income statement to separately disclose Unrealized gains (losses) on fair value of bitcoin and Realized (losses) gains on sale of bitcoin. The Company believes this presentation provides increased transparency on the nature of the respective financial statement line items. As a result, the Company reported $21.2 million and $4.9 million as Unrealized losses on fair value of bitcoin and Realized gains on sale of bitcoin, respectively, for the three months ended June 30, 2024 and $19.4 million and $4.9 million as Unrealized gains on fair value of bitcoin and Realized gains on sale of bitcoin, respectively, for the six months ended June 30, 2024, which were previously reported aggregated in Gains on fair value of bitcoin.

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. The most significant estimates inherent in the preparation of the Company’s financial statements include, but are not limited to, those related to equity instruments issued in share-based compensation arrangements, valuation of its level 3 asset, useful lives of property and equipment, the asset retirement obligation and the valuation allowance associated with the Company’s deferred tax assets, among others. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Unaudited condensed consolidated financial statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of the Company’s management, these unaudited condensed consolidated financial statements reflect all adjustments, which consist of only normal recurring adjustments necessary for the fair presentation of the balances and results for the periods presented. These unaudited condensed consolidated financial statement results are not necessarily indicative of results to be expected for the full fiscal year or any future period.

A detailed description of the Company’s significant accounting policies is included in the Company’s 2024 Form 10-K. You should read the unaudited condensed consolidated financial statements in conjunction with the Company’s audited consolidated financial statements and accompanying notes in the Company’s 2024 Form 10-K. There have been no material changes in the information disclosed in the notes to the Company’s audited consolidated financial statements included in the Company’s 2024 Form 10-K.

Revenue recognition

The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers (“ASC 606”). The core principle of the revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services.

The Company recognizes revenue on the same day that the control of the contracted service of providing hashrate transfers to the mining pool operator, which is the same day as contract inception. The noncash consideration received in the form of bitcoin is measured at 0:00:00 Coordinated Universal Time (“UTC”) using the Company’s principal market for bitcoin.

The contract is terminable at any time by either party with no substantive termination penalty. The Company’s enforceable right to compensation begins when, and lasts for as long as, the Company provides computing power to the mining pool operator; the Company’s performance obligation extends over the contract term given the Company’s continuous provision of hashrate. This period of time corresponds with the period of service for which the mining pool operator determines

CIPHER MINING INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

compensation due the Company. Given the terms of the contract, and the Company’s customary business practice, the contract effectively provides the Company with a contract that continuously renews throughout the day.

Segment information

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company has one operating segment, Bitcoin Mining, which through operations produces bitcoin to generate revenue. The Chief Operating Decision Maker (“CODM”) for the Company consists of the chief executive officer (“CEO”), and chief financial officer (“CFO”). The CODM reviews the performance of its segment primarily based on operating income when deciding on allocating resources between reinvesting in Bitcoin Mining or exploring alternative deployment of resources.

Restricted cash

Restricted cash represents amounts pledged as collateral to Luminant ET Services Company LLC (“Luminant”, and Vistra Operations Company, LLC (“Vistra”), a Luminant affiliate, primarily related to the Luminant Power Agreement (defined below in Note 4. Derivative Asset). The collateral restrictions related to the Luminant Power Agreement will lapse upon termination of the agreement.

Earnings per share

Basic earnings (loss) per share is computed by dividing net income (loss) allocated to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per common share adjusts net income (loss) and net income (loss) per common share for the effect of all potentially dilutive shares of Common Stock. Potentially dilutive common shares consist of the Company’s outstanding warrants to purchase Common Stock, Common Stock to settle convertible notes, as well as unvested restricted stock units (“RSUs”).

The dilutive effect of RSUs was calculated using the treasury stock method. For warrants that are liability-classified, during periods when the impact is dilutive, the Company assumes share settlement of the instruments as of the beginning of the reporting period and adjusts the numerator to remove the change in fair value of the warrant liability and adjusts the denominator to include the dilutive shares calculated using the treasury stock method.

The Company’s potentially dilutive common shares have been excluded from the computation of diluted net loss per common share when the effect would be to reduce the net loss per common share, or increase the net income per common share.

The following is a reconciliation of the numerator and denominator of the diluted earnings (loss) per share computations for the periods indicated below:

Recently adopted accounting pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 seeks to improve transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disclosures. The Company adopted this standard on January 1, 2025 and it did not have a significant impact on its condensed consolidated financial statements.

Recently issued accounting pronouncements

The Company continually assesses any new accounting pronouncements to determine their applicability. When it is determined that a new accounting pronouncement affects the Company’s financial reporting, the Company undertakes to determine the consequences of the change to its financial statements and assures that there are proper controls in place to ascertain that the Company’s financial statements properly reflect the change. The Company reviewed all other recently issued accounting pronouncements and concluded that they were either not applicable or not expected to have a significant impact on its condensed consolidated financial statements.

The Company held approximately 1,046 and 994 bitcoin at June 30, 2025, and December 31, 2024, respectively. The associated fair values and cost bases of bitcoin held were $112.1 million, and $102.2 million, respectively, at June 30, 2025, and $92.7 million, and $79.8 million, respectively at December 31, 2024. Fair value of bitcoin is estimated using the closing price at 23:59:59 UTC in the Company’s principal market, which is a Level 1 input (i.e., an observable input such as a quoted price in an active market for an identical asset). The Company accounts for bitcoin on a first-in-first-out (“FIFO”) basis.

(unaudited)

As of June 30, 2025, the Company had no bitcoin pledged as collateral related to the Coinbase Overnight Credit Facility. As of December 31, 2024, the Company had 345 bitcoin with a fair value of $32.2 million pledged as collateral related to the Coinbase Overnight Credit Facility. Restrictions on this bitcoin pledged as collateral lapse upon repayment of the outstanding balance drawn on this facility. The collateral pledged related to the Coinbase Overnight Credit Facility can be rehypothecated and therefore is derecognized from the Company’s ending bitcoin balance, and recorded in Receivable for bitcoin collateral on the Company’s consolidated balance sheet. Any difference in cost basis of the bitcoin transferred is recorded in Realized gains on sale of bitcoin on the Company’s consolidated statement of operations.

Additionally, the Company may pledge bitcoin as collateral related to bitcoin trading strategies. As of June 30, 2025, the Company had 8 bitcoin with a fair value of $0.9 million pledged relating to bitcoin trading strategies. Restrictions on this collateral will lapse in August 2025. As of December 31, 2024 the Company had no bitcoin pledged as part of trading strategies.

NOTE 4. DERIVATIVE ASSET

Luminant Power Agreement

On June 23, 2021, the Company entered into a power purchase agreement with Luminant, which was subsequently amended and restated on July 9, 2021, and further amended on February 28, 2022, August 26, 2022, and August 23, 2023 (as amended, the “Luminant Power Agreement”), for the supply of a fixed amount of electric power to the Odessa Facility at a fixed price for a term of five years, subject to certain early termination exemptions. The Luminant Power Agreement provides for subsequent automatic annual renewal unless either party provides written notice to the other party of its intent to terminate the agreement at least six months prior to the expiration of the then current term.

The Company’s management determined that the Luminant Power Agreement meets the definition of a derivative under ASC 815, Derivatives and Hedging (“ASC 815”). Accordingly, the Luminant Power Agreement is recorded at its estimated fair value each reporting period with the change in the fair value recorded in change in fair value of derivative asset in the consolidated statements of operations. See additional information regarding valuation of the Luminant Power Agreement derivative in Note 18. Fair Value Measurements.

The Company may opportunistically sell electricity in the ERCOT market in exchange for cash payments, rather than utilizing the power to mine for bitcoin at the Odessa Facility to manage the Company’s operating costs. From Power sales, the Company earned approximately $1.4 million and $1.1 million for the three months ended June 30, 2025, and 2024, respectively, and $2.4 million and $2.3 million for the six months ended June 30, 2025, and 2024, respectively, and recorded this amount within Costs and operating (expenses) income on the condensed consolidated statement of operations, with the corresponding cost of the power sold recorded in Cost of revenue.

in-progress related to the build out of the Black Pearl Facility was reclassified primarily into Buildings of $53.2 million with a useful life of 20 years, and Infrastructure of $71.6 million with a useful live of 10-20 years.

In June 2025, as part of placing the assets related to the Black Pearl Facility into service, the Company recorded an asset retirement obligation for the Black Pearl Facility to restore the land to its original condition at the end of the lease for $10.7 million, to be depreciated straight-line over the estimated remaining useful lives of the assets related to the facility.

Depreciation expense was approximately $43.9 million and $20.3 million respectively, for the three months ended June 30, 2025, and 2024, respectively, and included approximately $0.6 million and $0.6 million of accretion expense related to the Company’s asset retirement obligations, and $87.2 million and $37.2 million, respectively, for the six months ended June 30, 2025 and 2024, respectively, and included approximately $1.1 million and $0.9 million for the six months ended June 30, 2025 and 2024, of accretion expense related to the Company’s asset retirement obligations.

NOTE 6. DEPOSITS ON EQUIPMENT

In the fourth quarter of 2023, the Company entered into an agreement with Bitmain to purchase 7.1 EH/s of miners to be delivered in the first half of 2025 (the “Future Sales and Purchase Agreement”), all of which have been delivered with no remaining amount to be paid. In addition to amending the agreement on June 5, 2024 (such amendment, the “Supplemental Agreement”) to upgrade the miners and accelerate the delivery from the first half of 2025 to the fourth quarter of 2024, the Future Sales and Purchase Agreement also has an option to purchase an additional 8.7 EH/s in 2024. The Company paid $12.2 million upon signing the agreement in the fourth quarter of 2023 as a deposit, which can be used towards purchases under this option. On July 10, 2024, the Company entered into an agreement to further amend the Future Sales and Purchase agreement (the “Amendment Agreement”). The Amendment Agreement upgraded the miners to be purchased under the option, and extended the option expiration from December 31, 2024 to June 30, 2025.

On May 16, 2025, the Amendment Agreement was subsequently amended to reduce the total amount due to Bitmain under the Future Sales and Purchase Agreement and Supplemental Agreement from $120.2 million to $108.2 million, accelerate payment due under these agreements from progress payments through November 2025 to one payment due within 14 days of the execution of the new amendment, and provide the Company with a call option to purchase 493 bitcoin for $60.1 million with an expiration of August 30, 2025 and a call option to purchase 493 bitcoin for $60.1 million with an expiration of November 30, 2025 contingent upon exercising the first option (the “Bitmain Bitcoin Options”). The Company has paid nonrefundable deposits for miners of $165.9 million for this order as of June 30, 2025. The Bitmain Bitcoin Options are accounted for as derivatives and are classified in Prepaid expenses and other current assets as the expiration is within one year, and are carried at fair value. The loss on fair value of the Bitmain Bitcoin Options for the three and six months ended June 30, 2025 was $3.8 million and is recorded in Other expense in the condensed consolidated statement of operations.

In the second quarter of 2024, the Company entered into an agreement with Canaan to purchase 1.25 EH/s of miners to be delivered in the fourth quarter of 2024, all of which have been delivered with no remaining amount to be paid. Additionally, the contract included an option to purchase up to 160 MW of miners which the Company can exercise on or before June 30, 2025. The Company paid a deposit of $5.3 million associated with the option. Subsequent to quarter end, on July 2, 2025, the Company reached an agreement with Canaan to exercise the option to obtain 25 MW of miners for $21.3 million, and the Company paid an additional $8.5 million in deposits related to this order.

In the fourth quarter of 2024, the Company made a nonrefundable deposit with American Electric Power Company, Inc. (“AEP”) for $5.3 million related to construction costs to energize a wholly-owned site in LaSalle, Texas (the “Reveille Facility”), as a Contributions in Aid of Construction (“CIAC”) payment.

NOTE 7. INVESTMENT IN EQUITY INVESTEES

The Company accounts for its 49% equity ownership in each of Alborz LLC, Bear LLC and Chief Mountain LLC (the “Data Center LLCs”) using the equity method of accounting. The Company’s joint venture partner holds the remaining equity in each Data Center LLC entity.

During fiscal year 2022, the Company contributed miners and mining equipment to the Data Center LLCs. The contributed miners had a fair value that was below the cost paid by the Company to obtain them. As such, the Company recognized a loss at the time of the contributions, resulting in basis differences of the miners between the Company and the Data Center LLCs, which recorded the contributions of equipment from the Company at historical cost. The Company accretes these

NOTE 13. COMMITMENTS AND CONTINGENCIES

Commitments

In the normal course of business, the Company enters into contracts that contain a variety of indemnifications with its employees, licensors, suppliers and service providers. The Company’s maximum exposure under these arrangements, if any, is unknown as of June 30, 2025.

Contingencies

The Company, and its subsidiaries, are subject at times to various claims, lawsuits and governmental proceedings relating to the Company’s business and transactions arising in the ordinary course of business. The Company cannot predict the final outcome of such proceedings. Where appropriate, the Company vigorously defends such claims, lawsuits and proceedings. Some of these claims, lawsuits and proceedings seek damages, including consequential, exemplary or punitive damages, in amounts that could, if awarded, be significant. Certain of the claims, lawsuits and proceedings arising in the ordinary course of business are covered by the Company’s insurance program. The Company maintains property and various types of liability insurance in an effort to protect the Company from such claims. In terms of any matters where there is no insurance coverage available to the Company, or where coverage is available and the Company maintains a retention or deductible associated with such insurance, the Company may establish an accrual for such loss, retention or deductible based on current available information. In accordance with accounting guidance, if it is probable that an asset has been impaired or a liability has been incurred as of the date of the financial statements, and the amount of loss is reasonably estimable, then an accrual for the cost to resolve or settle these claims is recorded by the Company in the accompanying consolidated balance sheets. If it is reasonably possible that an asset may be impaired as of the date of the financial statements, then the Company discloses the range of possible loss. Expenses related to the defense of such claims are recorded by the Company as incurred and included in the accompanying consolidated statements of operations. Management, with the assistance of outside counsel, may from time to time adjust such accruals according to new developments in the matter, court rulings, or changes in the strategy affecting the Company’s defense of such matters. On the basis of current information, the Company does not believe there is a reasonable possibility that a material loss, if any, will result from any claims, lawsuits and proceedings to which the Company is subject to either individually, or in the aggregate.

Litigation

The Company is not a party to any material legal proceedings and is not aware of any pending or threatened claims. From time to time, the Company may be subject to various legal proceedings and claims that arise in the ordinary course of its business activities.

NOTE 14. DEBT

Short-term borrowings

Coinbase Master Loan Agreement

The Company has the Coinbase Master Loan Agreement, under which the Company established the Coinbase Overnight Credit Facility of $25.0 million. The Company will not incur commitment fees for unused portions of the Coinbase Overnight Credit Facility. The borrowing rate on amounts drawn against the Credit Facility is determined based on the Federal Funds Target Rate - Upper Bound, plus 2.5%, calculated daily based on a 365-day year and payable monthly for the duration of the loan, and market demand. Borrowings under the Coinbase Overnight Credit Facility are available on demand, open term, and collateralized by bitcoin transferred to the Lending Service Provider’s platform. Since the Lender has the right to rehypothecate the bitcoin held as collateral, the Company derecognized the bitcoin transferred. The Company has the right to receive the bitcoin back from the Lender upon repayment of the Coinbase Overnight Credit Facility, and as such recognized a receivable for bitcoin collateral measured at fair value of the bitcoin to be received upon repayment. The Company may also withdraw bitcoin if the loan becomes over-collateralized due to increases in bitcoin price.

Under the Coinbase Master Loan Agreement, the Company also established the “Term Loan Facility” with a limit of $35.0 million and maximum period of one year, with an interest rate to be determined upon drawdown.

2030 Convertible Notes

On May 22, 2025, the Company issued $172.5 million principal amount of the 2030 Convertible Notes with an interest rate of 1.75% (the “2030 Notes”). The 2030 Convertible Notes are senior, unsecured obligations with interest due semiannually on May 15 and November 15 each year beginning on November 15, 2025. The 2030 Notes will mature on May 15, 2030, unless earlier repurchased, redeemed or converted.

Before February 15, 2030, noteholders will have the right to convert their 2030 Convertible Notes only upon the occurrence of certain events. From and after February 15, 2030, noteholders may convert their 2030 Convertible Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. The Company will settle conversions by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election. As the Company has the option to settle in shares, these shares are considered potentially dilutive for the calculation of diluted earnings per share. The initial conversion rate is 224.9213 shares of the Company’s common stock per $1,000 principal amount of 2030 Convertible Notes, which represents an initial conversion price of approximately $4.45 per share of the Company’s common stock.

The 2030 Convertible Notes will be redeemable, in whole or in part (subject to certain limitations), at the Company’s option at any time, and from time to time, on or after May 22, 2028 and on or before the 30th scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such redemption notice. However, the Company may not redeem less than all of the outstanding 2030 Convertible Notes unless at least $50.0 million aggregate principal amount of 2030 Convertible Notes are outstanding and not called for redemption as of the time the Company sends the related redemption notice.

Service-based RSUs

A summary of the Company's unvested Service-Based RSU activity for the six months ended June 30, 2025 is shown below:


	Number of Shares	Weighted Average Grant Date Fair Value
Unvested at December 31, 2024	15,922,220	$	2.65
Granted	4,270,421	$	4.18
Vested(1)	(2,998,232)	$	2.73
Unvested at June 30, 2025	17,194,409	$	3.02
(1) Does not include RSUs that have not settled as of June 30, 2025

As of June 30, 2025, there was approximately $23.6 million of unrecognized compensation expense related to unvested Service-Based RSUs, which is expected to be recognized over a weighted-average vesting period of approximately 1.0 years.

If not fully vested upon grant, service-based RSUs awarded generally vest over a period ranging from three to four years in installments as determined by the Board.

Vesting is subject to the award recipient’s continuous service on the applicable vesting date; provided, that if the award recipient’s employment is terminated by the Company without “cause”, by award recipient for “good reason” (if applicable, as such term or similar term may be defined in any employment, consulting or similar service agreement between award recipient and the Company) or due to award recipient’s death or permanent disability, all unvested service-based RSUs will vest in full (unless otherwise specified in the agreement between the award recipient and the Company). In addition, in the event of a change in control, any unvested service-based RSUs will vest subject to the award recipient’s continuous service to the Company through such change in control. In addition, if the Company achieves a $10 billion market capitalization milestone (described further below) and the CEO remains in continuous service through such achievement, any then-unvested service-based RSUs awarded to the CEO will also vest.

Performance-Based RSUs

In 2021, the Company issued 4,257,710 performance-based RSUs (the “2021 Performance-Based RSUs”) at a weighted average grant date fair value of $7.76. None of the 2021 Performance-Based RSUs were vested as of June 30, 2025. There was no unrecognized compensation expense related to unvested performance-based RSUs at June 30, 2025.

One-third of the outstanding 2021 Performance-Based RSUs will vest upon the Company achieving a market capitalization equal to or exceeding $5 billion, $7.5 billion and $10 billion, in each case over a 30-day lookback period and subject to the CEO’s continuous service through the end of the applicable 30-day period. In the event of a change in control and CEO’s continuous service through such change in control, the per share price (plus the per share value of any other consideration) received by the Company’s stockholders in such change in control will be used to determine whether any of the market capitalization milestones are achieved (without regard to the 30-day lookback period). Any 2021 Performance-Based RSUs that do not vest prior to the CEO’s termination of service or, if earlier, in connection with a change in control will be forfeited for no consideration.

On February 26, 2025, the Company issued an additional 2,490,943 Performance-Based RSUs (the “2025 Performance-Based RSUs”) to the Company’s senior management team under the Incentive Award Plan at a weighted average grant date fair value of $5.01. None of the 2025 Performance-Based RSUs were vested as of June 30, 2025. There was approximately $9.2 million in unrecognized compensation expense related to the 2025 Performance-Based RSUs at June 30, 2025, which is expected to be recognized over a weighted-average vesting period of approximately 1.25 years, regardless of whether the market conditions required for vesting are achieved.

On December 31, 2025 the Company will calculate the number of PSUs expected to vest (the “Earned PSUs”), based upon the Company’s common stock achieving certain Total Shareholder Return (TSR) relative to the TSR of peer companies identified in the grant agreements and the overall TSR of the Company for the 2025 calendar year. The number of Earned PSUs will range from 0% to 225% of the number of 2025 Performance-Based RSU’s originally granted. Subject to the employee’s continuous service through the vesting date, one-third of the Earned PSUs will vest on December 31, 2025 and

CIPHER MINING INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

the remaining two-thirds of the Earned PSUs will vest in equal quarterly installments over the following two years with the first such vesting date occurring on March 31, 2026.

The grant date fair value of the 2025 Performance-Based RSUs was measured using a Monte Carlo simulation model based on the following assumptions:



Risk-free interest rate			4.14%

Expected volatility			111.5%

NOTE 18. FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial assets and liabilities measured at fair value are classified and disclosed in one of the following categories based on the inputs used to derive the fair value:

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 — Quoted prices in markets that are not active and financial instruments for which all significant inputs are observable, either directly or indirectly; or

Level 3 — Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable

The carrying values reported in the Company’s consolidated balance sheets for cash (excluding cash equivalents which are recorded at fair value on a recurring basis), accounts payable and accrued expenses and other current liabilities are reasonable estimates of their fair values due to the short-term nature of these items.

There were no transfers of financial instruments between Level 1, Level 2 and Level 3 during the periods presented.

Level 3 asset

The Company’s derivative asset, related to the Luminant Power Agreement, is divided between current and noncurrent assets, and was initially recorded on its consolidated balance sheets on the derivative asset’s effective date of July 1, 2022, with an offsetting amount recorded to change in fair value of derivative asset in costs and operating expenses on the consolidated statements of operations. Subsequent changes in fair value are also recorded to change in fair value of derivative asset. The Luminant Power Agreement was not designated as a hedging instrument. The estimated fair value of the Company’s derivative asset was derived from Level 2 and Level 3 inputs (i.e., unobservable inputs) due to a lack of

quoted prices for similar type assets and as such, is classified in Level 3 of the fair value hierarchy. Specifically, the discounted cash flow estimation models contain quoted spot and forward prices for electricity, as well as estimated usage rates consistent with the terms of the Luminant Power Agreement, the initial term of which is five years, and a remaining term of approximately 2.1 years. The valuations performed by the third-party valuation firm engaged by the Company utilized pre-tax discount rates of 5.33% and 5.96% as of June 30, 2025 and December 31, 2024, respectively, and include observable market inputs, but also include unobservable inputs based on qualitative judgment related to company-specific risk factors. Unrealized gains associated with the derivative asset within the Level 3 category include changes in fair value that were attributable to amendments to the Luminant Power Agreement, changes to the quoted forward electricity rates, as well as unobservable inputs (e.g., changes in estimated usage rates and discount rate assumptions).

The following table presents the changes in the estimated fair value of the derivative asset measured using significant unobservable inputs (Level 3) for the six months ended June 30, 2025 and 2024 (amounts in thousands):


	Six Months Ended June 30,
	2025		2024
Opening balance	$	85,670	$	93,591
Change in fair value	(8,150)		29,339
Ending balance	$	77,520	$	122,930

Level 3 liability

The Company’s Private Placement Warrants (as defined in Note 16. Warrants) were its only liability classified within Level 3 of the fair value hierarchy because the fair value is based on significant inputs that are unobservable in the market. The valuation of the Private Placement Warrants used assumptions and estimates the Company believes would be made by a market participant in making the same valuation. As of March 31, 2024, all Private Placement Warrants were converted to Public Warrants, and as such no Private Placement Warrants were outstanding as of June 30, 2025.

The Company engaged a valuation firm to determine the fair value of the Private Placement Warrants using a Black-Scholes option-pricing model and the quoted price of Common Stock. The following table presents significant assumptions utilized in the valuations of the Private Placement Warrants as of the dates indicated:


			December 31, 2023
Risk-free rate			4.00%
Dividend yield rate			0.00%
Volatility			124.0%

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report. This discussion contains forward‑looking statements based upon current plans, expectations and beliefs involving risks and uncertainties. Our actual results may differ materially from those anticipated in these forward‑looking statements as a result of various factors, including those set forth in Part II, Item 1A, “Risk Factors” and other factors set forth in other parts of this Quarterly Report.

Unless the context otherwise requires, references in this Quarterly Report to the “Company,” “Cipher,” “Cipher Mining,” “we,” “us” or “our” refers to Cipher Mining Inc. and its consolidated subsidiaries, unless otherwise indicated.

Overview

We develop and operate industrial-scale data centers. Our active portfolio and development pipeline is expected to consist of more than 3.0 GW of capacity across 11 sites. We currently operate two wholly-owned bitcoin mining data centers, a 207 MW site located in Odessa, Texas that draws fixed priced power from a power purchase agreement with its electricity provider (the “Odessa Facility”), and a 300 MW data center in Wink, Texas, of which 150 MW is operational as a bitcoin mining data center, that draws power from the power grid (the “Black Pearl Facility”), have equity investments in three partially-owned 40 MW bitcoin mining data centers, and have a pipeline of approximately 2.6 GW of potential capacity across seven sites in Texas. As we develop the sites in our pipeline and source future sites, locations and partnerships, we evaluate their suitability for either bitcoin mining or high-performance computing (“HPC”).

Our current intention is to continue expanding our business by developing and operating industrial-scale data centers for bitcoin mining and HPC, expanding capacity at our current data centers, continuing to execute our treasury management strategy and entering into other strategic arrangements, such as joint ventures, data center hosting and leasing agreements, or software licensing arrangements. We aim to be a market leader in innovation, including in bitcoin mining growth, data center construction and as a hosting partner to HPC companies.

As of July 31, 2025, the hashrate capacity of the Odessa Facility was approximately 11.3 EH/s and the hashrate capacity of the Black Pearl Facility was approximately 6.9 EH/s. Our joint ventures, in which we have a 49% equity interest, have a combined hashrate capacity of approximately 4.4 EH/s.

Recent Developments

On May 16, 2025, we amended our Future Sales and Purchase Agreement with Bitmain to reduce the total amount due to Bitmain, accelerate payments thereunder, and provide us with call options to purchase bitcoin. Refer to Note 6 - Deposits on equipment in the notes to our condensed consolidated financial statements included in this Quarterly Report, for further information. By prepaying those obligations that would come due between May and November, we reduced the cost of miners purchased for Phase I of the Black Pearl data center, and offset a portion of expected tariffs.

On May 22, 2025, we issued an aggregate principal amount of $172.5 million of 1.75% Convertible Senior Notes due 2030 (the “2030 Notes”). Refer to Note 14 - Debt in the notes to our Consolidated Financial Statements included in this Quarterly Report, for further information. With the net proceeds of the 2030 Notes, we completed Phase 1 of the Black Pearl Facility.

In June 2025, we energized and commenced bitcoin mining operations at Phase I of the Black Pearl facility. As of July 31, 2025, the facility is delivering approximately 6.9 EH/s of self-mining capacity.

On July 22, 2025, we terminated the Board Observer Agreement with Bitfury Top HoldCo B.V. and Bitfury Holding B.V.

Comparative Results for the Three Months Ended June 30, 2025 and 2024

Revenue

Revenue for the three months ended June 30, 2025 was $43.6 million compared to $36.8 million for the three months ended June 30, 2024 and was generated from bitcoin mining operations at the Odessa and Black Pearl Facilities. The increase year over year was primarily driven by higher bitcoin prices in the current quarter compared to the prior year quarter, partially offset by less bitcoin mined as a result of the halving in April of 2024, which reduced the bitcoin received for mining a block from 6.25 bitcoin to 3.125 bitcoin.

Cost of revenue

Cost of revenue for the three months ended June 30, 2025 was $15.3 million, compared with $14.3 million for the three months ended June 30, 2024, and consisted primarily of power costs at the Odessa Facility under the Luminant Power Agreement. The increase in the three months ended June 30, 2025 is driven primarily by additional power costs from the energization of the Black Pearl and Barber Lake facilities in the second quarter of 2025.

Compensation and benefits

Compensation and benefits for the three months ended June 30, 2025 was $15.7 million, a decrease of $0.6 million compared to $16.3 million for the three months ended June 30, 2024. The decrease was primarily due to the expiration of the expense on certain Share-based compensation awards in the first quarter of 2025.

General and administrative

General and administrative expenses increased by $0.7 million to $9.1 million during the three months ended June 30, 2025 from $8.4 million for the three months ended June 30, 2024. The increase was primarily driven by an increase in legal fees related to strategic initiatives.

Depreciation and amortization

Depreciation for the three months ended June 30, 2025 was $44.1 million, an increase of $23.8 million compared to Depreciation and amortization of $20.3 million for the three months ended June 30, 2024. The increase was primarily due to additional depreciation expense on miners acquired as part of the Odessa fleet upgrade.

Change in fair value of derivative asset

Change in fair value of derivative asset was a $15.5 million loss for the three months ended June 30, 2025 and was driven by the fair value of the Luminant Power Agreement. The estimated fair value of our derivative asset was derived from Level 2 and Level 3 inputs, and, due to a lack of quoted prices for similar type assets, is classified in Level 3 of the fair value hierarchy. Specifically, the discounted cash flow estimation models contain quoted spot and forward prices for electricity, as well as estimated usage rates consistent with the terms of the Luminant Power Agreement, the initial term of which is five years.

Power sales

At the Odessa Facility we sold excess electricity that was available under the Luminant Power Agreement back to the ERCOT market through Luminant. We sold power for proceeds of $1.4 million and $1.1 million for the three months ended June 30, 2025, and 2024, respectively. Power sales fluctuate each period based on power and bitcoin prices which are both volatile.

Equity in losses of equity investees

Equity in losses of equity investees totaled $1.7 million for the three months ended June 30, 2025 compared to losses of $0.6 million for the three months ended June 30, 2024. Equity in losses of equity investees consists of our 49% share in the earnings (losses) generated by our three partially-owned mining sites, and the accretion of the basis differences in our investments in the equity investees that resulted from contributions of miners during the year ended December 31, 2022. We are accreting these basis differences over the five-year useful life of the miners.

Unrealized (losses) gains on fair value of bitcoin

Unrealized gains on fair value of bitcoin totaled $17.1 million for the three months ended June 30, 2025, compared to losses of $21.2 million for the three months ended June 30, 2024. Unrealized (losses) gains on fair value of bitcoin is driven by the cost of bitcoin mined compared to the price of bitcoin at the end of the period.

Realized (losses) gains on sale of bitcoin

Realized losses on sale of bitcoin totaled $3.6 million for the three months ended June 30, 2025 compared to gains of $4.9 million for the three months ended June 30, 2024. Realized gains and losses on sale of bitcoin is a result of selling bitcoin at prices different from the cost basis.

Other income (expense)

Other income totaled $0.4 million for the three months ended June 30, 2025, compared to Other expense of $1.4 million for three months ended June 30, 2024. The decrease is primarily related to interest expense incurred from the Coinbase Loan Facility and the 2030 Convertible Note issuance in the current year.

Benefit for income taxes

For the three months ended June 30, 2025, we recorded a benefit for income taxes of $0.9 million primarily driven by net losses in the current period. For the three months ended June 30, 2024, we recorded a benefit for income taxes of $0.5 million.

Comparative Results for the Six Months Ended June 30, 2025 and 2024

Revenue

Revenue for the six months ended June 30, 2025 was $92.5 million, compared to $84.9 million for the six months ended June 30, 2024, and was generated from bitcoin mining operations at the Odessa and Black Pearl Facilities. The increase year over year was primarily driven by an increase in the average bitcoin price in the current year, partially offset by a decrease in the amount of bitcoin mined as a result of the bitcoin halving in April 2024.

Cost of revenue

Cost of revenue for the six months ended June 30, 2025 was $30.2 million, compared with $29.1 million for the six months ended June 30, 2024, and consisted primarily of power costs at the Odessa Facility. The increase is primarily due to power draw at the Black Pearl and Barber Lake Facilities .

Compensation and benefits

Compensation and benefits for the six months ended June 30, 2025 was $30.0 million, compared to $29.3 million for the six months ended June 30, 2024. The increase was primarily due to an increase in headcount year-over-year.

General and administrative

General and administrative expenses for the six months ended June 30, 2025 was $18.0 million, an increase of $3.6 million compared to $14.4 million for the six months ended June 30, 2024. The increase was primarily driven by an increase in legal fees related to strategic initiatives.

Depreciation and amortization

Depreciation and amortization for the six months ended June 30, 2025 was $87.6 million, an increase of $50.1 million compared to Depreciation and amortization of $37.5 million for the six months ended June 30, 2024. The increase was primarily due to increased miners, and mining equipment at the Odessa Facility as a result of the Odessa fleet upgrade in the fourth quarter of 2024, as well as the change in the estimated useful life of our miners from five years to three years as of June 1, 2024.

Change in fair value of derivative asset

Change in fair value of derivative asset was a $8.2 million decrease for the six months ended June 30, 2025 and was driven by the fair value of the Luminant Power Agreement. The estimated fair value of our derivative asset was derived from Level 2 and Level 3 inputs, and, due to a lack of quoted prices for similar type assets, is classified in Level 3 of the fair value hierarchy. Specifically, the discounted cash flow estimation models contain quoted spot and forward prices for electricity, as well as estimated usage rates consistent with the terms of the Luminant Power Agreement, the initial term of which is five years.

Power sales

At our Odessa Facility, we sell excess electricity that was available under the Luminant Power Agreement, but not needed in our mining operations, back to the ERCOT market through Luminant. We sold power for proceeds of $2.4 million and $2.3 million for the six months ended June 30, 2025, and 2024, respectively. Power sales fluctuate each period based on power and bitcoin prices, which are volatile.

Equity in income (losses) of equity investees

Equity in losses of equity investees totaled $7.0 million for the six months ended June 30, 2025 compared to income of $0.2 million for the six months ended June 30, 2024. Equity in losses of equity investees consists of our 49%

share in the earnings (losses) generated by our three partially-owned mining sites, and the accretion of the basis differences in our investments in the equity investees that resulted from contributions of miners during the year ended December 31, 2022. We are accreting these basis differences over the five-year useful life of the miners. For the six months ended June 30, 2025, we recognized roughly $4 million as our 49% share of a one-time impairment charge on the miners of Alborz LLC, net of accretion.

Unrealized (losses) gains on fair value of bitcoin

Unrealized losses on fair value of bitcoin totaled $3.0 million for the six months ended June 30, 2025, compared to Unrealized gains on fair value of bitcoin of $19.4 million for the six months ended June 30, 2024. Unrealized (losses) gains on fair value of bitcoin is driven by the cost of bitcoin mined compared to the price of bitcoin at the end of the period.

Realized gains on sale of bitcoin

Realized gains on sale of bitcoin totaled $8.6 million for the six months ended June 30, 2025 compared to $4.9 million in the prior year period. In both periods, this is driven by selling bitcoin above our cost basis.

Other expense (income)

Other expense totaled $0.4 million for the six months ended June 30, 2025, compared to $0.1 million of Other income for the six months ended June 30, 2024. The increase of Other expense in the current year is driven primarily from an increase in interest expense related to the Coinbase Loan Facility and the 2030 Convertible Notes.

Income tax benefit (expense)

For the six months ended June 30, 2025, we recorded a provision for income taxes of $1.1 million as a result of projected income for the current year in the jurisdictions which we operate. For the six months ended June 30, 2024, we recorded a provision for income taxes of $6.1 million.

Liquidity and Capital Resources

We had cash used in operations of $103.5 million for the six months ended June 30, 2025. As of June 30, 2025, we had cash and cash equivalents of $62.7 million, total stockholders’ equity of $748.9 million and an accumulated deficit of $266.2 million. We fund operations primarily through a combination of at-the-market stock issuances, short-term and long-term financing arrangements, and bitcoin sales.

We have established an at-the-market sales agreement with Cantor Fitzgerald & Co., Canaccord Genuity LLC, Needham & Company, LLC, Compass Point Research & Trading, LLC, Keefe, Bruyette & Woods, Inc., Virtu Americas LLC, and BTIG, LLC (each, an “Agent” and, together, the “Agents”), pursuant to which we may, from time to time, sell shares of our common stock having an aggregate offering price of up to $725.7 million. For the three months ended June 30, 2025, we received net proceeds on sales of 14.2 million shares of common stock under the Amended and Restated Sales Agreement of approximately $51.5 million (net of commissions and expenses) at an average net selling price of $3.63 per share. For more information on our at-the-market sales agreement and our at-the-market offerings, see Note 15. Stockholders’ Equity.

We have a master loan agreement with Coinbase Credit, Inc., as lender, and Coinbase, Inc., as lending service provider. Pursuant to the master loan agreement, we currently have a secured line of credit up to $25.0 million (the “Coinbase Overnight Credit Facility”). We will not incur commitment fees for unused portions of the Coinbase Overnight Credit Facility. The borrowing rate on amounts drawn against the Coinbase Overnight Credit Facility is determined on the basis of the Federal Funds Target Rate - Upper Bound, plus 2.5%, calculated daily based on a 365-day year and payable monthly for the duration of the loan. Borrowings under the Coinbase Overnight Credit Facility are available on demand, open term, and collateralized by bitcoin transferred to the lending service provider’s platform. As of June 30, 2025 we had nothing drawn on the Coinbase Overnight Credit Facility. Additionally, we have a term loan facility with Coinbase with a limit of $35.0 million and maximum period of one year (the “Term Loan Facility”). As of June 30, 2025, we were in compliance with the covenants under the Coinbase Overnight Credit Facility.

We enter into agreements with Luxor Technology Corporation (“Luxor”) when needed to borrow bitcoin for short-term periods, which we are able to use as a source of short-term financing.

On May 22, 2025, we issued $172.5 million principal amount of convertible notes due in 2030 with an interest rate of 1.75% (the “2030 Convertible Notes”). The 2030 Convertible Notes are senior, unsecured obligations with interest due semiannually on May 15 and November 15 each year beginning on November 15, 2025. For more information on our 2030 Convertible Notes, see Note 14. Debt.

Management believes that our existing financial resources, combined with projected cash and bitcoin inflows from our data centers, our intent and ability to sell bitcoin received or earned, and our intent and ability to sell common stock through at-the-market offerings will be sufficient to enable us to meet our operating and capital requirements for at least 12 months from the date the condensed consolidated financial statements included in this Quarterly Report are issued and the foreseeable future.

Cash Flows

The following table summarizes our sources and uses of cash for the periods indicated (in thousands):


	Six Months Ended June 30,
	2025		2024
Net cash used in operating activities	$	(103,455)	$	(51,988)
Net cash used in investing activities	(110,470)		(62,313)
Net cash provided by financing activities	271,044		150,753
Net increase (decrease) in cash and cash equivalents	$	57,119	$	36,452

Operating Activities

Net cash used in operating activities increased by $51.5 million to $103.5 million for the six months ended June 30, 2025 from $52.0 million for the six months ended June 30, 2024. We incurred a net loss of $84.8 million for the six months ended June 30, 2025, compared to net income of $24.6 million for the six months ended June 30, 2024, representing a decrease of $109.4 million. Cash flows used in operating activities was impacted by a $96.7 million increase in non-cash items, primarily driven a $37.5 million increase in the fair value of derivative asset, an $18.7 million increase in gains on the fair value of bitcoin, and a $50.0 million increase in depreciation. Additionally, changes in assets and liabilities resulted in an increase in cash used of $38.8 million between the six months ended June 30, 2025 and 2024.

Investing Activities

Cash used in investing activities increased by $48.2 million to $110.5 million of net cash used in investing activities for the six months ended June 30, 2025 compared to $62.3 million of net cash used in investing activities for the six months ended June 30, 2024. This change primarily related to a $126.6 million increase in deposits related to new miner purchases, and a $40.1 million increase in purchases of Property and equipment related to building out the Black Pearl facility, partially offset by an increase of $111.0 million of proceeds from sale of Bitcoin, and a $7.6 million decrease in contributions to equity investees related to our joint ventures.

Financing Activities

Cash flows provided by financing activities increased by $120.3 million to $271.0 million net cash provided by financing activities for the six months ended June 30, 2025 from $150.8 million net cash provided by financing activities for the six months ended June 30, 2024. This change was primarily driven by a $50.0 million increase in proceeds from treasury stock reissued for PIPE investment and a $167.1 million increase in proceeds from issuance of convertible notes, net of issuance costs, partially offset by a $76.5 million decrease in proceeds from the issuance of common stock during the six months ended June 30, 2025.

Contractual Obligations and Other Commitments

On December 17, 2021, we entered into a lease agreement for office space, amended in the second quarter of 2024, with a term through May 2029. Monthly rent payments associated with the amended lease are approximately $0.2 million.

We also entered into a series of agreements with affiliates of Luminant ET Services Company LLC ( “Luminant”), including the Lease Agreement dated June 29, 2021, with amendment and restatement on July 9, 2021 (as amended and

restated, the “Luminant Lease Agreement”). The Luminant Lease Agreement leases a plot of land to us where our data center, ancillary infrastructure and electrical system (the “Interconnection Electrical Facilities” or “substation”) have been set up for our Odessa Facility. We entered into the Luminant Lease Agreement and the Luminant Purchase and Sale Agreement to build the infrastructure necessary to support our planned operations. Management determined that the Luminant Lease Agreement and the Luminant Purchase and Sale Agreement should be combined for accounting purposes under ASC 842 (collectively, the “Combined Luminant Lease Agreement”) and that amounts exchanged under the combined contract should be allocated to the various components of the overall transaction based on relative fair values.

Our management determined that the Combined Luminant Lease Agreement contains two lease components; and the components should be accounted for together as a single lease component, because the effect of accounting for the land lease separately would be insignificant.

The Combined Luminant Lease Agreement commenced on November 22, 2022 and has an initial term of five years, with renewal provisions that are aligned with the Luminant Power Agreement. Financing for use of the land and substation is provided by Luminant affiliates. Despite lease commencement in November 2022, we had not been required by Luminant to make any lease payments for the substation prior to July 2023, therefore we accrued amounts due under the Combined Luminant Lease Agreement in accrued expenses and other current liabilities on its consolidated balance sheet.

On August 23, 2023, we entered into a second amendment of the Luminant Lease Agreement, the terms of which included an amended payment schedule, reflecting monthly installments of principal and interest totaling $19.7 million on an undiscounted basis, due over the remaining four-year period starting in July 2023. This amendment did not have a material impact on our condensed consolidated financial statements.

Non-GAAP Financial Measures

We are providing supplemental financial measures for Adjusted Earnings (Loss) and Adjusted Earnings (Loss) per share - diluted, in each case that exclude the impact of (i) the non-cash change in fair value of derivative asset, (ii) share-based compensation expense, (iii) depreciation and amortization, (iv) deferred income tax expense, (v) nonrecurring gains and losses and (vi) the non-cash change in fair value of warrant liability. These supplemental financial measures are not measurements of financial performance under accounting principles generally accepted in the United States (“GAAP”) and, as a result, these supplemental financial measures may not be comparable to similarly titled measures of other companies. Management uses these non-GAAP financial measures internally to help understand, manage, and evaluate our business performance and to help make operating decisions. We believe the use of these non-GAAP financial measures can also facilitate comparison of our operating results to those of our competitors by excluding certain items that vary in our industry based on company policy.

Non-GAAP financial measures are subject to material limitations as they are not in accordance with, or a substitute for, measurements prepared in accordance with GAAP. For example, we expect that share-based compensation expense, which is excluded from the non-GAAP financial measure, will continue to be a significant recurring expense over the coming years and is an important part of the compensation provided to certain employees, officers and directors. Similarly, we expect that depreciation and amortization will continue to be a recurring expense over the term of the useful life of the related assets. Our non-GAAP financial measures are not meant to be considered in isolation and should be read only in conjunction with our condensed consolidated financial statements included elsewhere in this Quarterly Report, which have been prepared in accordance with GAAP. We rely primarily on such condensed consolidated financial statements to understand, manage and evaluate our business performance and use the non-GAAP financial measures only supplementally.

The following is a reconciliation of our Adjusted Earnings to the most directly comparable GAAP measure for the periods indicated (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,

Critical Accounting Policies, and Use of Estimates

For a description of our policies regarding our critical accounting estimates, see "Critical Accounting Policies and Estimates" of Part II, Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2024 Form 10-K. During the three months ended June 30, 2025, there were no significant changes in our critical accounting policies and estimates or the application or the results of the application of those policies to our unaudited condensed consolidated financial statements from those previously disclosed in our 2024 Form 10-K.

Recent Accounting Pronouncements

Information regarding recent accounting pronouncements applicable to us, adopted and not yet adopted as of the date of this report, is included in Note 2 to our unaudited condensed consolidated financial statements located in “Part I - Financial Information, Item 1. Financial Statements” in this Quarterly Report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

The following discussion of our market risks involves forward-looking statements. Actual results could differ materially from those projected in our forward-looking statements. For more information regarding the forward-looking statements used in this section and elsewhere in this Quarterly Report, see the Cautionary Note Regarding Forward-Looking Statements at the forepart of this Quarterly Report.

Our primary market risks are described below. We use various strategies to manage these risks; however, they may still from time to time impact our condensed consolidated financial statements.

Bitcoin Price Risk

We hold bitcoin on our inventory at fair value, and as such we are exposed to the impact of the change in bitcoin price. As of June 30, 2025, we had 1,046 bitcoin in inventory. A 10% decrease in the price of bitcoin would result in an estimated $11.2 million increase in Net loss for the six months ended June 30, 2025.

Power Price Risk

The estimated fair value of our Derivative asset related to our power purchase agreement is derived from Level 2 and Level 3 inputs. Specifically, the discounted cash flow estimation models contain quoted spot and forward prices for electricity. A 10% decrease in power prices would result in an estimated $14.8 million decrease in the estimated fair value of the Derivative asset and increase in Net loss for the six months ended June 30, 2025.

Item 4. Controls and Procedures.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

We conducted an evaluation of the effectiveness of our “disclosure controls and procedures”, as defined by Rules 13a-15(e) and 15d-15(e) of the Exchange Act, as of June 30, 2025, the end of the period covered by this Quarterly Report. This evaluation was done under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, our disclosure controls and procedures were not effective at the reasonable assurance level as of June 30, 2025.

Remediation of Material Weakness

As noted in the 2024 Form 10-K, during management’s assessment of internal controls over financial reporting, a material weakness was identified related to certain Information Technology General Controls (“ITGCs”) over change management controls.

As management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, we understand the importance of developing a resolution plan aligned with management and overseen by the Audit Committee of our Board of Directors.

Since the material weakness related to certain ITGCs over change management controls and lack of related compensating automated process-level and manual controls was identified, management began implementing and has continued to implement and refine measures designed to ensure that control deficiencies contributing to the material weakness are remediated, such that these controls are designed, implemented, and operating effectively. During the three months ended June 30, 2025, management continued implementing its enhanced program change management controls for certain

systems impacting the Company’s processes around revenue recognition and design of manual key reconciliation processes. The Company continued to make progress but work still remains to ensure reliability of such controls. Our plan continues to include the following, and management will continue to assess additional opportunities for remediation on an ongoing basis:

•Continue advancing our remediation efforts by devoting resources throughout 2025 to key areas of financial reporting and information technology.

•Maintain our engagement with advisory firms to support the evaluation and enhancement of the Company’s controls related to the material weakness described above.

•Further implement and refine processes and controls and engage external resources as needed to ensure that controls are appropriately designed, implemented, and operating effectively.

We recognize that the material weakness in our internal control over financial reporting will not be considered remediated until the remediated controls operate for a sufficient period of time and can be tested and concluded by management to be designed and operating effectively. Because our remediation efforts involve our outsourced service providers, we cannot provide any assurance that these remediation efforts will be successful or that our internal control over financial reporting will be effective as a result of these efforts.

We continue to evaluate and work to improve our internal control over financial reporting related to the identified material weakness and management may determine to take additional measures to address control deficiencies or determine to modify the remediation plan described above. In addition, we report the progress and status of the above remediation efforts to the Audit Committee on a periodic basis.

Changes in Internal Control over Financial Reporting

Other than the remediation efforts described above, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

We are not a party to any material pending legal proceedings. From time to time, we may be subject to legal proceedings and claims arising in the ordinary course of business. The outcome of any such claims or proceedings, regardless of the merits, is inherently uncertain. There have been no material changes to such proceedings previously disclosed in our 2024 Form 10-K.

Item 1A. Risk Factors.

Our business, financial condition and operating results can be affected by a number of factors, whether currently known or unknown, including but not limited to the risk factors as previously disclosed in Part I, Item 1A, “Risk Factors” of our 2024 Form 10-K, which is incorporated herein by reference. Other than the additional risk factors herein, there have been no material changes to the risk factors previously disclosed in our 2024 Form 10-K.

Our indebtedness and liabilities could limit the cash flow available for our operations, expose us to risks that could adversely affect our business, financial condition and results of operations and impair our ability to satisfy our obligations under the 2030 Notes.

We incurred $172.5 million principal amount of additional indebtedness as a result of the 2030 Notes offering completed in May 2025. We may also incur additional indebtedness to meet future financing needs. Our indebtedness could have significant negative consequences for our security holders and our business, results of operations and financial condition by, among other things:

•increasing our vulnerability to adverse economic and industry conditions;

•limiting our ability to obtain additional financing;

•requiring the dedication of a substantial portion of our cash flow from operations to service our indebtedness, which will reduce the amount of cash available for other purposes;

•limiting our flexibility to plan for, or react to, changes in our business;

•diluting the interests of our existing stockholders as a result of issuing shares of our common stock upon conversion of the 2030 Notes; and

•placing us at a possible competitive disadvantage with competitors that are less leveraged than us or have better access to capital.

Our business may not generate sufficient funds, and we may otherwise be unable to maintain sufficient cash reserves, to pay amounts due under our indebtedness, including the 2030 Notes, and our cash needs may increase in the future. In addition, future indebtedness that we may incur may contain financial and other restrictive covenants that limit our ability to operate our business, raise capital or make payments under our other indebtedness. If we fail to comply with these covenants or to make payments under our indebtedness when due, then we would be in default under that indebtedness, which could, in turn, result in that and our other indebtedness becoming immediately payable in full.

We may be unable to raise the funds necessary to repurchase the 2030 Notes for cash following a fundamental change or on a specified optional repurchase date or to pay any cash amounts due upon maturity or conversion of the 2030 Notes, and our other indebtedness may limit our ability to repurchase the 2030 Notes or to pay any cash amounts due upon their maturity or conversion.

Holders of the 2030 Notes may, subject to limited exceptions, require us to repurchase their 2030 Notes on May 15, 2028, and following a fundamental change, at a cash repurchase price generally equal to the principal amount of the 2030 Notes to be repurchased, plus accrued and unpaid interest, if any. Upon maturity of the 2030 Notes, we must pay their principal amount and accrued and unpaid interest in cash, unless they have been previously repurchased, redeemed or converted. In addition, upon conversion, we will satisfy part or all of our conversion obligation in cash unless we elect to settle conversions solely in shares of our common stock. We may not have enough available cash or be able to obtain financing at the time we are required to repurchase the 2030 Notes or pay any cash amounts due upon their maturity or conversion. In

addition, applicable law, regulatory authorities and the agreements that we may have in the future governing our other indebtedness may restrict our ability to repurchase the 2030 Notes or to pay any cash amounts due upon their maturity or conversion. Our failure to repurchase 2030 Notes or to pay any cash amounts due upon their maturity or conversion when required will constitute a default under the indenture. A default under the indenture or the fundamental change itself could also lead to a default under agreements governing our other indebtedness, which may result in that other indebtedness becoming immediately payable in full. We may not have sufficient funds to satisfy all amounts due under the other indebtedness and the 2030 Notes.

Provisions in the 2030 Notes indenture could delay or prevent an otherwise beneficial takeover of us.

Certain provisions in the 2030 Notes and related indenture could make a third-party attempt to acquire us more difficult or expensive. For example, if a takeover constitutes a fundamental change, then noteholders will have the right to require us to repurchase their 2030 Notes for cash. In addition, if a takeover constitutes a make-whole fundamental change, then we may be required to temporarily increase the conversion rate. In either case, and in other cases, our obligations under the 2030 Notes and the indenture could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management, including in a transaction that noteholders or holders of our common stock may view as favorable.

The conditional conversion feature of the 2030 Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the 2030 Notes is triggered, holders of such notes will be entitled to convert the 2030 Notes at any time during specified periods at their option. If one or more holders elect to convert their 2030 Notes, we may elect to settle all or a portion of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their 2030 Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the 2030 Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

The accounting method for the 2030 Notes could adversely affect our reported financial condition and results.

The accounting method for the 2030 may adversely affect our reported earnings and financial condition.

The issuance costs for the 2030 Notes are treated as a debt discount for accounting purposes and will be amortized into interest expense over the term of the 2030 Notes. As a result of this amortization, the interest expense that we expect to recognize for the 2030 Notes for accounting purposes will be greater than the cash interest payments we will pay on the 2030 Notes, which will result in lower reported income.

Furthermore, if any of the conditions to the convertibility of the 2030 Notes is satisfied, then we may be required under applicable accounting standards to reclassify the liability carrying value of the 2030 Notes as a current, rather than a long-term, liability. This reclassification could be required even if no investors convert their 2030 Notes and could materially reduce our reported working capital.

The issuance of shares of our common stock upon conversion of the 2030 Notes will dilute the ownership interests of our stockholders and could depress the trading price of our common stock.

Upon conversion of the 2030 Notes being offered in the 2030 Notes offering, we will satisfy part or all of our conversion obligations in shares of our common stock, unless we elect to settle conversions solely in cash. The issuance of shares of our common stock upon conversion of the 2030 Notes will dilute the ownership interests of our stockholders, which could depress the trading price of our common stock. In addition, the market’s expectation that conversions may occur could depress the trading price of our common stock even in the absence of actual conversions. Moreover, the expectation of conversions could encourage the short selling of our common stock, which could place further downward pressure on the trading price of our common stock.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

None.

Item 3. Defaults Upon Senior Securities.

None.

Item 4. Mine Safety Disclosures.

Not applicable.

Item 5. Other Information.

(a) Disclosure in lieu of reporting on a Current Report on Form 8-K.

(b) Material changes to the procedures by which security holders may recommend nominees to the board of directors.

None.

Our officers and directors from time to time may adopt trading plans to transact in our common stock for a variety of reasons, including tax considerations, investment diversification, or other personal reasons. During the three months ended June 30, 2025, certain of our officers and directors adopted a pre-arranged stock trading plan intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Securities Exchange Act of 1934, as amended (each such plan, a “Rule 10b5-1 Plan”), as described below. On May 12, 2025, Patrick Kelly, Co-President and Chief Operating Officer, adopted a Rule 10b5-1 Plan that is intended to satisfy the affirmative defense of Rule 10b5-1(c) for the sale of up to 414,204 shares of our common stock until August 7, 2026. On June 5, 2025, William Iwaschuk, Co-President, Chief Legal Officer and Corporate Secretary, adopted a Rule 10b5-1 Plan that is intended to satisfy the affirmative defense of Rule 10b5-1(c) for the sale of up to 487,956 shares of our common stock until May 8, 2026. No other directors or “officers” (as defined in Section 16a-1(f) of the Securities Exchange Act of 1934, as amended) adopted, terminated, or modified a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K, during the three months ended June 30, 2025.
