The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. In the opinion of the Company, the accompanying unaudited interim consolidated financial statements reflect all adjustments, consisting of only normal recurring adjustments, considered necessary for a fair statement of such interim results. All significant intercompany accounts and transactions have been eliminated. Certain prior period amounts have been reclassified to conform with current period presentation.

Certain amounts in the unaudited interim consolidated statement of cash flows for the nine months ended September 30, 2022 were restated as previously disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022. The misstatements related solely to incorrectly calculating the impact of noncash activity on purchase and deposits on plant and equipment, resulting in an understatement of net cash used in investing activities and a corresponding overstatement of net cash used in operating activities as originally included in the respective interim unaudited consolidated statements of cash flows.

The results for the unaudited interim consolidated statements of operations are not necessarily indicative of results to be expected for the year ending December 31, 2023 or for any future interim period. The unaudited interim consolidated financial statements do not include all the information and notes required by U.S. GAAP for complete financial statements. The accompanying unaudited interim financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

The Company identified an error in its historical unaudited interim consolidated statements of cash flows for each of the first three quarters of 2023. In accordance with Staff Accounting Bulletin No. 99, “Materiality,” the Company determined that these unaudited interim consolidated financial statements were materially misstated and should be restated. The misstatement relates solely to incorrectly classifying payments of contingent value rights liability as an investing activity instead of as a financing activity in the respective unaudited interim consolidated statements of cash flows. These payments were made in accordance with the Contingent Value Rights Agreement related to the Company's merger with RM 101 Inc.

(see Note 3). The unaudited interim consolidated balance sheets, unaudited interim consolidated statements of operations and unaudited interim consolidated statements of stockholders' equity for each of the first three quarters of 2023 were not impacted and do not require restatement. The restated unaudited interim consolidated statements of cash flows information is included in Note 17.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for (but are not limited to) such items as the fair values of assets acquired and liabilities assumed in business combinations, the fair value of contingent consideration issued in a business combination, the establishment of useful lives for property, plant and equipment and intangible assets, the impairment of goodwill and held for sale assets, the fair value of equity securities or warrants to purchase common stock issued individually or as a component of a debt or equity offering, the fair value of changes to the conversion terms of embedded conversion features, the fair value and requisite service periods of stock-based compensation, the fair value of assets received in nonmonetary transactions, the establishment of right-of-use assets and lease liabilities that arise from leasing arrangements, the timing of commencement of capitalization for plant and equipment, impairment of indefinite-lived intangible assets, impairment of long-lived assets, recoverability of deferred tax assets and the recording of various accruals. These estimates are made after considering past and current events and assumptions about future events. Actual results could differ from those estimates.

The Company currently maintains cash and cash equivalent balances primarily at two financial institutions that are insured by the Federal Deposit Insurance Corporation (“FDIC”). The Company’s accounts at these institutions are insured, up to $250,000, by the FDIC. As of September 30, 2023, the Company’s bank balances exceeded the FDIC insurance limit in an amount of approximately $0. To reduce its risk associated with the failure of such financial institutions, the Company evaluates at least annually the rating of the financial institutions in which it holds deposits.

On March 12, 2023, Signature Bank (“SBNY”) was closed by its state chartering authority, the New York State Department of Financial Services. On the same date the FDIC was appointed as receiver and transferred all customer deposits and substantially all of the assets of SBNY to Signature Bridge Bank, N.A., a full-service bank that is operated by the FDIC. All funds were transferred out of Signature Bridge Bank, N.A. by April 5, 2023.

The Company considers cash and marketable securities to be restricted when withdrawal or general use is legally restricted. The Company reports restricted cash in the consolidated balance sheets and determines current or non-current classification based on the expected duration of the restriction. The Company had no restricted cash as of September 30, 2023. The restricted cash included in the consolidated balance sheet as of December 31, 2022 is restricted primarily due to being held in escrow in accordance with an asset purchase agreement governing the sale of certain RM 101 assets (see Note 3).

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision–making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision–making group (“CODM”) is composed of the chief executive officer, chief operating officer and chief strategy officer. Currently, the Company operates solely in the Digital Currency Mining segment. The Company’s mining operations are located in the United States, and the Company has employees only in the United States and views its mining operations as one operating segment as the CODM reviews financial information on a consolidated basis in making decisions regarding resource allocations and assessing performance. Prior to the sale of substantially all of RM 101’s assets, through its ownership of RM 101, the Company operated in the Imaging Technology segment. TeraWulf classified the RM 101 segment as held for sale and discontinued operations in these consolidated financial statements (see Note 3).

Property, plant and equipment are recorded at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets (generally 5 years for computer equipment and 4 years for miners). Leasehold improvements and electrical equipment are depreciated over the shorter of their estimated useful lives or the lease term. Property, plant and equipment, net includes deposits, amounting to approximately $16.3 million and $57.6 million as of September 30, 2023 and December 31, 2022, respectively, on purchases of such assets, including miners, which would be included in property, plant and equipment upon receipt.

Interest related to construction of assets is capitalized when the financial statement effect of capitalization is material, construction of the asset has begun, and interest is being incurred. Interest capitalization ends at the earlier of the asset being substantially complete and ready for its intended use or when interest costs are no longer being incurred.

The Company reviews its long-lived assets, including property, plant and equipment, for impairment when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts. Any impairment loss recorded is measured as the amount by which the carrying value of the assets exceeds the fair value of the assets. During the three and nine months ended September 30, 2023 and 2022, the Company determined that no impairment of long-lived assets exists.

The Company determines if an arrangement is a lease at inception and, if so, classifies the lease as an operating or finance lease. Operating leases are included in right-of-use (“ROU”) asset, current portion of operating lease liability, and operating lease liability, net of current portion in the consolidated balance sheets. Finance leases would be included in property, plant and equipment, current portion of finance lease liabilities, and finance lease liabilities, net of current portion in the consolidated balance sheets. The Company does not recognize a ROU asset or lease liability for short-term leases having initial terms of 12 months or less and instead recognizes rent expense on a straight-line basis over the lease term. In an arrangement that is determined to be a lease, the Company includes both the lease and nonlease components as a single component and accounts for it as a lease when the Company would otherwise recognize the cost associated with both the lease and nonlease components in a similar fashion.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease ROU assets and liabilities are recognized at commencement date, and subsequently remeasured upon changes to the underlying lease arrangement, based on the present value of lease payments over the lease term. If the lease does not provide an implicit rate or if the implicit rate is not determinable, the Company generally uses an estimate of its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at the commencement date. The ROU asset also includes any lease prepayments made and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

Costs associated with operating lease ROU assets are recognized on a straight-line basis within operating expenses or selling, general and administrative, as appropriate, over the term of the lease. Variable lease costs are recognized as incurred and primarily consist of common area maintenance charges not included in the measurement of right-of-use assets and operating lease liabilities. Finance ROU lease assets are amortized within operating expenses or selling, general and administrative expenses, as appropriate, on a straight-line basis over the shorter of the estimated useful lives of the assets or, in the instance where title does not transfer at the end of the lease term, the lease term. The interest component of a finance lease is included in interest expense and recognized using the effective interest method over the lease term.

The Company evaluates amendments to its debt instruments in accordance with applicable U.S. GAAP. This evaluation includes comparing (1) if applicable, the change in fair value of an embedded conversion option to that of the carrying amount of the debt immediately prior to amendment and (2) the net present value of future cash flows of the amended debt to that of the original debt to determine, in each case, if a change greater than 10% occurred. In instances where the net present value of future cash flows or the fair value of an embedded conversion option, if any, changed more than 10%, the Company applies extinguishment accounting. In instances where the net present value of future cash flows and the fair value of an embedded conversion option, if any, changed less than 10%, the Company accounts for the amendment to the debt as a debt modification. For debt that has been amended more than once in a twelve-month period, the debt terms that existed just prior to the earliest amendment occurring in the prior twelve months are applied to the 10% test, provided modification accounting was previously applied. Gains and losses on debt amendments that are considered extinguishments are recognized in current earnings. Debt amendments that are considered debt modifications are accounted for prospectively through yield adjustments, based on the revised terms. Legal fees and other costs incurred with third parties that are directly related to debt modifications are expensed as incurred and generally are included in interest expense in the

The Company accounts for its issuance of convertible debt and convertible equity instruments in accordance with applicable U.S. GAAP. In connection with that accounting, the Company assesses the various terms and features of the agreement in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) No. 480 “Distinguishing Liabilities from Equity” (“ASC 480”) and ASC 815 “Derivatives and Hedging Activities” (“ASC 815”). ASC 480 requires liability accounting for certain financial instruments, including shares that embody an unconditional obligation to transfer a variable number of shares, provided that the monetary value of the obligation is based solely or predominantly on one of the following three characteristics: (1) a fixed monetary amount known at inception, (2) variations in something other than the fair value of the issuer’s equity shares or (3) variations in the fair value of the issuer’s equity shares, but the monetary value to the counterparty moves in the opposite direction as the value of the issuer’s shares. In accordance with ASC 815, the Company assesses the various terms and features of the agreement to determine whether or not they contain embedded derivative instruments that are required under ASC 815 to be accounted for separately from the host contract and recorded on the balance sheet at fair value. The fair value of derivative liabilities, if any, is required to be revalued at each reporting date, with corresponding changes in fair value recorded in the current period's operating results.

The Company applies ASC 480 and ASC 815 to assist in the determination of whether warrants issued for the purchase of Common Stock should be classified as liabilities or equity. Warrants that are determined to require liability classification are measured at fair value upon issuance and are subsequently remeasured to their then fair value at each subsequent reporting period with changes in fair value recorded in current earnings. Warrants that are determined to require equity classification are measured at fair value upon issuance and are not subsequently remeasured unless they are required to be reclassified. All warrants granted by the Company to date are classified as equity.

The Company accounts for goods and services exchanged in nonmonetary transactions at fair value unless the underlying exchange transaction lacks commercial substance or the fair value of the assets received or relinquished is not reasonably determinable, in which case the nonmonetary exchange would be measured based on the recorded amount of the nonmonetary asset relinquished.

The Company classifies a business as held for sale in the period in which management commits to a plan to sell the business, the business is available for immediate sale in its present condition, an active program to complete the plan to sell the business is initiated, the sale of the business within one year is probable and the business is being marketed at a reasonable price in relation to its fair value.

Newly acquired businesses that meet the held-for-sale classification criteria upon acquisition are reported as discontinued operations. Upon a business’ classification as held for sale, net assets are measured for impairment. An impairment loss is recorded for long-lived assets held for sale when the carrying amount of the asset exceeds its fair value less cost to sell. Other assets and liabilities are generally measured for impairment by comparing their carrying values to their respective fair values. A long-lived asset is not depreciated or amortized while it is classified as held for sale.

The Company recognizes revenue under the FASB 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 following five steps are applied to achieve that core principle:

In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised good or service that is distinct. A performance obligation meets ASC 606’s definition of a “distinct” good or service (or bundle of goods or services) if both of the following criteria are met: the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct), and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to transfer the good or service is distinct within the context of the contract).

The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer. The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. When determining the transaction price, an entity must consider the effects of all of the following:

Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The transaction price is allocated to each performance obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized when that performance obligation is satisfied, at a point in time or over time as appropriate.

The Company has entered into an arrangement with a cryptocurrency mining pool (the Foundry USA Pool) to perform hash computation (i.e. hashrate) for the mining pool in exchange for consideration. Providing hash computation services to a mining pool is an output of the Company’s ordinary activities. The provision of such hash computation services is the sole performance obligation. The mining pool arrangement is terminable at any time without substantial penalty by Foundry USA Pool and may be terminated without substantial penalty by the Company upon providing one Contract Day’s, as defined, prior written notice. The Company’s enforceable right to compensation only begins when and continues

while the Company provides hash computation services to its customer, the mining pool operator. Accordingly, the contract term with Foundry USA Pool is deemed to be less than 24 hours and to continuously renew throughout the day. Additionally, the Company concluded that the mining pool operator’s (i.e., the customer’s) renewal right is not a material right because the renewal rights do not include any discounts; that is, the terms, conditions, and compensation amounts are at the then-current market rates.

The mining pool applies the Full Pay Per Share (“FPPS”) payout model. Under the FPPS model, in exchange for providing hash computation services to the pool, the Company is entitled to pay-per-share base amount and transaction fee reward compensation, calculated on a daily basis, at an amount that approximates the total bitcoin that could have been mined and transaction fees that could have been awarded using the Company’s hash computation services, based upon the then current blockchain difficulty. Under this model, the Company is entitled to compensation, payable in bitcoin, regardless of whether the pool operator successfully records a block to the bitcoin blockchain.

The transaction consideration the Company receives, if any, is noncash consideration and is all variable. Because digital currency is considered noncash consideration, fair value of the digital currency award received would generally be determined using the quoted price of the related digital currency in the Company’s principal market at the time of contract inception. The Company has adopted an accounting policy to aggregate individual contracts with individual terms less than 24-hours within each intraday period and apply a consistent valuation point, the start of day Coordinated Universal Time (00:00:00 UTC), to value the related noncash consideration. Revenue is recognized when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur, which is the same day that control of the contracted service transfers to the mining pool, which is the same day as the contract inception. After every 24-hour contract term, the mining pool transfers the digital currency consideration to our designated digital currency wallet.

The Company’s current hosting contracts are service contracts with a single performance obligation. The service the Company provides primarily includes hosting the customers’ miners in a physically secure data center with electrical power, internet connectivity, ambient air cooling and available maintenance resources. Hosting revenue is recognized over time as the customer simultaneously receives and consumes the benefits of the Company’s performance. The Company recognizes hosting revenue to the extent that a significant reversal of such revenue will not occur. Data center hosting customers are invoiced and payments are due on a monthly basis. While the majority of consideration is paid in cash, certain consideration is payable in digital currency. Because digital currency is considered noncash consideration, fair value of the digital currency award received is determined using the quoted price of the related digital currency in the Company’s principal market at the time of contract inception. The Company has one data center hosting contract with a customer, which expires in December 2023, for which the quoted price of bitcoin in the Company’s principal market at the time of contract inception was approximately $38,000. The Company recorded miner hosting revenue of $1.8 million and $5.8 million during the three and nine months ended September 30, 2023, respectively, and $1.4 million and $1.8 million during the three and nine months ended September 30, 2022, respectively.

Digital currency, net is comprised of bitcoin earned as noncash consideration in exchange for providing hash computation services to a mining pool as well as in exchange for data center hosting services which are accounted for in connection with the Company’s revenue recognition policy disclosed above. From time to time, the Company also receives bitcoin as distributions-in-kind from its joint venture. Digital currency is included in current assets in the consolidated balance sheets due to the Company’s ability to sell it in a highly liquid marketplace and because the Company reasonably expects to liquidate its digital currency to support operations within the next twelve months. The Company sells its digital currency on a first-in-first-out basis.

Digital currency is accounted for as intangible assets with indefinite useful lives. An intangible asset with an indefinite useful life is not amortized but assessed for impairment annually, or more frequently if events or changes in circumstances indicate it is more likely than not that the asset is impaired. Impairment exists when the carrying amount exceeds its fair

value. In testing for impairment, the Company has the option to first perform a qualitative assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more likely than not that an impairment exists, a quantitative impairment test is not necessary. If the Company concludes otherwise, it is required to perform a quantitative impairment test.

The Company has elected to bypass the optional qualitative impairment assessment and to track its bitcoin activity daily for impairment assessment purposes. The Company determines the fair value of its bitcoin on a nonrecurring basis in accordance with ASC 820 based on quoted prices on the active trading platform that the Company normally transacts and has determined is its principal market for bitcoin (Level 1 inputs), based on all information that is reasonably available. The Company performs an analysis each day to identify whether events or changes in circumstances, principally decreases in the quoted price of bitcoin on the active trading platform, indicate that it is more likely than not that its bitcoin are impaired. For impairment testing purposes, the lowest intraday trading price of bitcoin is identified at the single bitcoin level (one bitcoin). The excess, if any, of the carrying amount of bitcoin and the lowest daily trading price of bitcoin represents a recognized impairment loss. To the extent an impairment loss is recognized, the loss establishes the new cost basis of the asset. Subsequent reversal of previously recorded impairment losses is prohibited. The Company recognized impairment of digital currency of $0.9 million and $2.2 million during the three and nine months ended September 30, 2023, respectively, and $0.1 million and $0.7 million during the three and nine months ended September 30, 2022, respectively.

Digital currency awarded to the Company through its mining activities are included as an adjustment to reconcile net loss to cash used in operating activities on the consolidated statements of cash flows. Proceeds from sales of digital currency are included within cash flows from operating activities on the consolidated statements of cash flows and any realized gains or losses from such sales are included in costs and operating expenses on the consolidated statements of operations. The receipt of digital currency as distributions-in-kind from equity investees are included within supplemental disclosures of noncash investing activities.

The Company periodically issues restricted stock units (“RSUs”) to employees and non-employees in non-capital raising transactions for services. In accordance with the authoritative guidance for share-based payments FASB ASC 718 “Compensation – Stock Compensation,” the Company measures stock-based compensation cost at the grant date, based on the estimated fair value of the award. For RSUs with time-based vesting, the fair value is determined by the Company’s stock price on the date of grant. For RSUs with vesting based on market conditions, the effect of the market condition is considered in the determination of fair value on the grant date using a Monte Carlo simulation model. The Company has not issued stock options.

Expense for RSUs is recognized on a straight-line basis over the employee’s or non-employee’s service period, including the derived service period for RSUs with market conditions. Stock-based compensation for RSUs with market conditions is recorded over the derived service period unless the market condition is satisfied in advance of the derived service period, in which case a cumulative catch-up is recognized as of the date of achievement. Stock-based compensation for RSUs with market conditions is recorded regardless of whether the market conditions are met unless the service conditions are not met. The Company accounts for forfeitures as they occur. The Company recognizes excess tax benefits or deficiencies on vesting or settlement of awards as discrete items within income tax benefit or provision within net income (loss) and the related cash flows are classified within operating activities.

Proceeds related to participation in demand response programs are recorded as a reduction in cost of revenue in the consolidated statements of operations in the period corresponding to the underlying associated demand response program period. The Company recorded demand response program amounts of approximately $1.7 million and $2.5 million during the three and nine months ended September 30, 2023, respectively, and $0.1 million during each of the three and nine months ended September 30, 2022.

The Company computes earnings (loss) per share using the two-class method required for participating securities. The two-class method requires income available to common stockholders for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed.

Basic loss per share of common stock is computed by dividing the Company’s net loss attributed to common stockholders (adjusted for preferred stock dividends declared or accumulated) by the weighted average number of shares of common stock outstanding during the period. Convertible preferred stock, which are participating securities because they share in a pro rata basis any dividends declared on common stock but because they do not have the obligation to share in the loss of the Company, are excluded from the calculation of basic net loss per share. Diluted loss per share reflects the effect on weighted average shares outstanding of the number of additional shares outstanding if potentially dilutive instruments, if any, were converted into common stock using the treasury stock method or as-converted method as appropriate. The computation of diluted loss per share does not include dilutive instruments in the weighted average shares outstanding, as they would be anti-dilutive. The Company’s dilutive instruments or participating securities as of September 30, 2023 include convertible preferred stock, common stock warrants and RSUs issued for services. The Company’s dilutive instruments or participating securities as of December 31, 2022 include convertible preferred stock, convertible promissory notes, common stock warrants and RSUs issued for services. If the entire liquidation preference of the Convertible Preferred Stock (as defined in Note 13) was converted at its conversion price as of September 30, 2023, the Company would issue approximately 1.1 million shares of Common Stock. As of September 30, 2023, Common Stock warrants outstanding were 49,120,642 with a weighted average strike price of $0.58 and total RSUs outstanding were 6,422,632.

The Company and its joint venture have contracted with two suppliers for the provision of bitcoin miners and one mining pool operator. The Company does not believe that these counterparties represent a significant performance risk. Revenue from one data center hosting customer represents 9.5% and 12.7% of consolidated revenue for the three and nine months ended September 30, 2023, respectively, and represents 36.2% and 32.9% of consolidated revenue for the three and nine months ended September 30, 2022, respectively. The Company only operates bitcoin mining facilities. While the Company may choose to mine other digital currencies or pursue other data center services in the future, it has no plans to do so currently. If the market value of bitcoin declines significantly, the consolidated financial condition and results of operations of the Company may be adversely affected.
