EXPLANATORY NOTE

EXPLANATORY NOTE

Restatement of Previously Issued Financial Statements

TeraWulf Inc. (“TeraWulf” or the "Company") is filing this Amendment No. 1 to its Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2023 (the "Form 10-Q/A"), which was originally filed with the U.S. Securities and Exchange Commission (the "SEC") on November 13, 2023, for the purpose of correcting an identified error in its historical unaudited interim consolidated financial statements. On November 22, 2023, the Company filed a Current Report on Form 8-K with the SEC disclosing the determination by the audit committee of the Company’s board of directors, after considering the recommendations of management and discussions with RSM US LLP, the Company’s independent registered public accounting firm, that, as a result of the error described below, the Company would restate previously issued unaudited consolidated financial statements and related disclosures as of and for the interim period ended September 30, 2023. The misstatement relates solely to incorrectly classifying “payments of contingent value rights liability related to proceeds from sale of net asset held for sale” as an investing activity instead of as a financing activity in the respective unaudited interim consolidated statements of cash flows. See Note 3 to the Consolidated Financial Statements for a discussion of the payments made in accordance with the Contingent Value Rights Agreement related to the Company's merger with RM 101 Inc. (formerly known as IKONICS Corporation) on December 13, 2021. The Company determined that its unaudited interim consolidated financial statements in the quarterly reports for the periods ended March 31, 2023, June 30, 2023 and September 30, 2023 (the “Relevant Periods”) were materially misstated and should be restated. The restatements are set forth in detail in Note 17 to the Consolidated Financial Statements.

Internal Control & Disclosure Control Considerations

Management assessed the effectiveness of internal control over financial reporting and identified a material weakness, resulting in the conclusion by the Company's Chief Executive Officer and Chief Financial Officer that the Company's internal control over financial reporting and the Company's disclosure controls and procedures were not effective as of September 30, 2023. The material weakness relates solely to the inadequate design and operation of management’s review controls over classification in the consolidated statements of cash flows of payments made related to business combinations. Management is taking steps to remediate the material weakness in the Company's internal control over financial reporting, as described in Part I, Item 4, “Controls and Procedures.”

Non-Reliance on Previously Filed Reports

TeraWulf believes that presenting all of this information regarding the Relevant Periods in this Form 10-Q/A allows investors to review all pertinent data in a single presentation. Therefore, the Company does not plan to amend its previously filed Quarterly Reports on Form 10-Q for June 30, 2023 and March 31, 2023. The misstatement relates solely to incorrectly classifying "payments of contingent value rights liability related to proceeds from sale of net assets held for sale" as an investing activity instead of as a financing activity in the respective unaudited interim consolidated statements of cash flows (the "Misclassification"). Accordingly, investors should no longer rely upon the Company’s previously released financial statements for the Relevant Periods and any earnings releases or other communications relating to these Relevant Periods with respect to the Misclassification. The financial information that has been previously filed or otherwise reported for the Relevant Periods with respect to the Misclassification is superseded by the information in Note 17 to the Consolidated Financial Statements in this Form 10-Q/A. TeraWulf will also correct previously reported financial information for this Misclassification in its future filings, as applicable.

Items Amended in this Form 10-Q/A

The following sections in the Original Report are revised in this Form 10-Q/A to reflect the restatement:

• Part I, Item 1: Financial Statements

• Part I, Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations

• Part I, Item 4: Controls and Procedures

• Part II, Item 1A: Risk Factors

In addition, this Form 10-Q/A includes an updated signature page and new certifications of the Company’s Chief Executive Officer and Chief Financial Officer, dated as of the date of this filing (Exhibits 31.1, 31.2, 32.1 and 32.1).

Because these amendments are treated as corrections of errors to the Company's prior period financial results, the amendments are considered to be a "restatement” under U.S. generally accepted accounting principles (“US GAAP”). Accordingly, the revised financial information included in this Form 10-Q/A has been identified as “As Restated.”

Forward-Looking Statements

This Quarterly Report contains “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995, which involve risks and uncertainties. All statements other than statements of historical facts contained in this Quarterly Report, including statements regarding our strategy, future operations, future financial position, future revenue, projected costs, prospects, plans, objectives of management, and expected market growth are forward-looking statements. These forward- looking statements are contained principally in the sections entitled “Risk Factors” and “Management’s Discussion and Analysis.” Without limiting the generality of the preceding sentence, any time we use the words “expects,” "intends,” “will,” “anticipates,” “believes,” “confident,” “continue,” “propose,” “seeks,” “could,” “may,” “should,” “estimates,” “forecasts,” “might,” “goals,” “objectives,” “targets,” “planned,” “projects,” and, in each case, their negative or other various or comparable terminology and similar expressions, we intend to clearly express that the information deals with possible future events and is forward-looking in nature. However, the absence of these words or similar expressions does not mean that a statement is not forward-looking. For TeraWulf, particular uncertainties that could cause our actual results to be materially different than those expressed in our forward-looking statements include, without limitation:

•conditions in the cryptocurrency mining industry, including any prolonged substantial reduction in cryptocurrency prices, and specifically, the value of bitcoin, which could cause a decline in the demand for TeraWulf’s services;

•competition among the various providers of data mining services;

•the need to raise additional capital to meet our business requirements in the future, which may be costly or difficult to obtain or may not be obtained (in whole or in part) and, if obtained, could significantly dilute the ownership interests of TeraWulf’s shareholders;

•the ability to implement certain business objectives and the ability to timely and cost-effectively execute integrated projects;

•adverse geopolitical or economic conditions, including a high inflationary environment;

•security threats or unauthorized or impermissible access to our data centers, our operations or our digital wallet;

•counterparty risk with respect to our digital asset custodian and our mining pool provider;

•employment workforce factors, including the loss of key employees;

•changes in governmental safety, health, environmental and other regulations, which could require significant expenditures;

•liability related to the use of TeraWulf’s services;

•currency exchange rate fluctuations; and

•other risks, uncertainties and factors included or incorporated by reference in this Quarterly Report, including those set forth under “Risk Factors” and those included under the heading “Risk Factors” in our annual report on Form 10-K, filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 31, 2023 (the “Original 10-K”), as amended by our annual report on Form 10-K/A, filed with the SEC on May 5, 2023, for the fiscal year ended December 31, 2022 (the “10-K/A” and together with the Original 10-K, the “Annual Report on Form 10-K”).

These forward-looking statements reflect our views with respect to future events as of the date of this Quarterly Report and are based on assumptions and subject to risks and uncertainties. Given these uncertainties, you should not place undue reliance on these forward-looking statements. These forward-looking statements represent our estimates and assumptions only as of the date of this Quarterly Report and, except as required by law, we undertake no obligation to update or review publicly any forward-looking statements, whether as a result of new information, future events or otherwise after the date of this Quarterly Report. We anticipate that subsequent events and developments will cause our views to change. You should read this Quarterly Report completely and with the understanding that our actual future results may be materially different from what we expect. Our forward-looking statements do not reflect the potential impact of any future acquisitions, merger, dispositions, joint ventures or investments we may undertake. We qualify all of our forward-looking statements by these cautionary statements.

NOTE 1 – ORGANIZATION

Organization

TeraWulf Inc. (“TeraWulf” or the “Company”) is a digital asset technology company with a core business of digital infrastructure and energy development to enable sustainable bitcoin mining. TeraWulf’s principal business consists of developing and operating bitcoin mining facilities in the United States that are fueled by clean, low cost and reliable power sources. The Company generates revenue in the form of bitcoin by providing hash computation services to a mining pool operator to mine bitcoin and validate transactions on the global bitcoin network using application-specific integrated circuit computers (“ASIC” or “miners”) owned by the Company. The earned bitcoin are routinely sold for U.S. dollars. The Company also earns revenue by providing miner hosting services to third parties. 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.

TeraWulf currently owns and operates, either independently or through a joint venture, two bitcoin mining facilities: the Lake Mariner Facility located in upstate New York; and the Nautilus Cryptomine Facility located in central Pennsylvania. The Company’s wholly-owned Lake Mariner Facility began mining bitcoin in March 2022 and, as of September 30, 2023, the Company has energized two buildings and additional infrastructure comprising 110 MW of capacity. The Nautilus Cryptomine Facility, which has been developed and constructed through a joint venture (see Note 11), commenced mining operations in February 2023 and, in April 2023, achieved full energization of the Company’s allotted infrastructure capacity of 50 MW.

On December 13, 2021, TeraWulf Inc. completed a strategic business combination (the “Merger”) with IKONICS Corporation ("IKONICS") , a Minnesota corporation, pursuant to which, among other things, the Company effectively acquired IKONICS and became a publicly traded company on the National Association of Securities Dealers Automated Quotations (“Nasdaq”), which was the primary purpose of the business combination. IKONICS’ traditional business was the development and manufacturing of high-quality photochemical imaging systems for sale primarily to a wide range of printers and decorators of surfaces. Customers’ applications were primarily screen printing and abrasive etching. TeraWulf initially classified the IKONICS business as held for sale and discontinued operations in its consolidated financial statements. During the year ended December 31, 2022, the Company completed sales of substantially all of IKONICS’ historical net assets (see Note 3). Subsequent to the asset sales, IKONICS’ name was changed to RM 101 Inc. (“RM 101”).

Risks and Uncertainties

Liquidity and Financial Condition

The Company incurred a net loss attributable to common stockholders of $63.7 million and negative cash flows from continuing operations of $6.9 million for the nine months ended September 30, 2023. As of September 30, 2023, the Company had balances of cash and cash equivalents and restricted cash of $6.6 million, a working capital deficiency of $95.5 million, total stockholders’ equity of $153.9 million and an accumulated deficit of $249.4 million. The Company has 5.5 EH/s of operating capacity across the Lake Mariner Facility and the Nautilus Cryptomine Facility as of September 2023, which the Company expects to result in positive cash flows from operations subsequently. To date, the Company has relied primarily on proceeds from its issuances of debt and equity and sale of bitcoin mined to fund its principal operations.

In accordance with development of its bitcoin mining facilities, during the nine months ended September 30, 2023, the Company invested approximately $41.4 million for purchases of and deposits on plant and equipment. Also, during the nine months ended September 30, 2023, the Company invested $2.8 million in its joint venture (see Note 11). TeraWulf expects to fund its business operations and incremental infrastructure buildout primarily through positive cash flows from operations, including sales of mined bitcoin or through miner hosting services, cash on the balance sheet and the issuance of equity securities.

During the nine months ended September 30, 2023, the Company accomplished several notable steps to achieve expected positive cash flows from operations, namely: (1) the Company amended its long-term debt agreement (see Note 9) to, among other changes, remove the fixed principal amortization through April 7, 2024 and, potentially, through maturity, (2) the Company received net proceeds of $57.7 million through the issuance of shares of our common stock, par value $0.001 per share (the “Common Stock”), Common Stock warrants and convertible promissory notes (see Notes 13 and 14), which along with cash flows from operations, is expected to be sufficient to fund the Company’s operating expenses in the months prior to achieving a free cash flow positive enterprise (3) commenced mining activities at the Nautilus Cryptomine Facility and the Company deems that it has funded all known and expected capital commitments at that facility, (4) the

Company received substantially all contracted miners from the miner suppliers and has no remaining outstanding financial commitments under the miner purchase agreements (see Notes 11 and 12) for the existing operations at the Lake Mariner Facility and the Nautilus Cryptomine Facility, (5) the Company has received the quantity of miners sufficient to fully utilize mining capacity in service at the Lake Mariner Facility for buildings one and two and the Nautilus Cryptomine Facility and (6) the construction activities at the Lake Mariner Facility for buildings one and two and the Nautilus Cryptomine Facility are substantially complete as of September 30, 2023, although the Company intends to expand its infrastructure at the Lake Mariner Facility. Additionally, if a business need requires its use, the Company has an active at-the-market sales agreement for sale of shares of Common Stock having an aggregate offering price of up to $200.0 million (the “ATM Sales Agreement”), which had a remaining capacity of $162.2 million as of September 30, 2023. The issuance of Common Stock under this agreement would be made pursuant to the Company’s effective registration statement on Form S-3 (Registration statement No. 333-262226). The Company has determined that it is probable that these actions and conditions will allow the Company to generate positive cash flows from operations and be able to realize its assets and discharge its liabilities and commitments in the normal course of business and, therefore, there is not substantial doubt about the Company’s ability to continue as a going concern through at least the next twelve months. The consolidated financial statements do not include any adjustments that might result from TeraWulf’s possible inability to continue as a going concern.

COVID-19

As of May 2023, the World Health Organization no longer considers COVID-19 a global health emergency, however the Company may from time to time experience disruptions to its business operations resulting from continued COVID-19-related supply interruptions, including miner delivery interruptions. The Company may also experience COVID-19-related delays in construction and obtaining necessary equipment in a timely fashion. To date, the Company has experienced minimal delays due to COVID-19 among its suppliers and contractors.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

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.

Prior Interim Period Restatement

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

(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.

Use of Estimates in the Financial Statements

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.

Cash and Cash Equivalents

Highly liquid instruments with an original maturity of three months or less are classified as cash equivalents. As of September 30, 2023 and December 31, 2022, the Company had cash and cash equivalents of $6.6 million and $8.3 million, including restricted cash, respectively.

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.

Restricted Cash

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).

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets that total to the amounts shown in the consolidated statements of cash flows (in thousands):

	September 30, 2023		December 31, 2022
Cash and cash equivalents	$	6,595	$	1,279
Restricted cash	—		7,044
Cash and cash equivalents and restricted cash	$	6,595	$	8,323

Segment Reporting

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

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.

TERAWULF INC. AND SUBSIDIARIES

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.

Impairment of Long-lived Assets

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.

Leases

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.

As of September 30, 2023 and December 31, 2022, the Company was not a counterparty to any finance leases.

Debt Modification

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

13

TERAWULF INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

consolidated statements of operations. Amounts paid by the Company to the lenders, including upfront fees and the fair value of warrants issued, are included in future cash flows for accounting treatment determination and, if debt modification is applicable, are also included in the determination of yield adjustment.

Convertible Instruments

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.

Warrants

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.

Nonmonetary Transactions

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.

Stock Issuance Costs

Stock issuance costs are recorded as a reduction to issuance proceeds. Stock issuance costs incurred prior to the closing of the related issuances, including under shelf registration statements, are recorded in other assets in the consolidated balance sheets if the closing of the related issuance is deemed probable.

Held for Sale and Discontinued Operations Classification

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.

Revenue Recognition

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:

•Step 1: Identify the contract with the customer

•Step 2: Identify the performance obligations in the contract

•Step 3: Determine the transaction price

•Step 4: Allocate the transaction price to the performance obligations in the contract

•Step 5: Recognize revenue when the Company satisfies a performance obligation

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).

If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.

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

•Constraining estimates of variable consideration

•The existence of a significant financing component in the contract

•Noncash consideration

•Consideration payable to a customer

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.

Mining Pool

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

15

TERAWULF INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

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.

There is no significant financing component in these transactions.

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.

Consideration payable to the customer in the form of a pool operator fee, which is incurred only to the extent that the Company has generated FPPS consideration, is deducted from the bitcoin the Company receives and is recorded as contra-revenue, as it does not represent a payment for a distinct good or service.

Data Center Hosting

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

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.

Cost of Revenue

Cost of revenue for mining pool revenue is comprised primarily of direct costs of electricity but excludes depreciation which is separately presented. Cost of revenue for data center hosting is comprised primarily of direct costs of electricity, labor and internet provision.

Stock-based Compensation

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.

Power Curtailment Credits

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.

Other Income

Other income consists primarily of interest income on bank deposits. The Company recorded other income of $0 and $39,000 during the three and nine months ended September 30, 2023, respectively, related to a disgorgement of short-swing profits arising from trades by a non-management insider under Section 16(b) of the Securities and Exchange Act of 1934.

Loss per Share

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.

Concentrations

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.

NOTE 3 – BUSINESS COMBINATION, ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS

On December 13, 2021, the Company completed the Merger with RM 101 (formerly known as IKONICS Corporation) pursuant to which, among other things, the Company effectively acquired RM 101 and became a publicly traded company on the Nasdaq. The consideration in the Merger included, among other things, contractual contingent value rights (“CVR”) per a Contingent Value Rights Agreement (the “CVR Agreement”). Pursuant to the CVR Agreement, each shareholder of RM 101 as of immediately prior to the Merger, received one non-transferable CVR for each outstanding share of common stock of RM 101 then held. The holders of the CVRs are entitled to receive 95% of the Net Proceeds (as defined in the CVR Agreement), if any, from the sale, transfer, disposition, spin-off, or license of all or any part of the pre-merger business of RM 101. Payments under the CVR Agreement are calculated quarterly, are paid on the sixtieth day after the respective quarterly calculation period and are subject to a reserve of up to 10% of the Gross Proceeds (as defined in the CVR Agreement) from such transaction or more under certain conditions. The Company made a CVR payment in the amount of $3.9 million in February 2023 related to the quarterly calculation for the fourth quarter of 2022. The Company made a CVR payment in the amount of $5.7 million in May 2023 related to the quarterly calculation for the first quarter of 2023. The CVRs do not confer to the holders thereof any voting or equity or ownership interest in TeraWulf. The CVRs are not transferable, except in limited circumstances, and are not listed on any quotation system or traded on any securities exchange. The CVR Agreement will terminate after all payment obligations to the holders thereof have been satisfied.

Holders of CVRs (the “CVR Holders”) will not be eligible to receive payment for dispositions, if any, of any part of the pre-merger business of RM 101 after the eighteen-month anniversary of the closing of the Merger.

In August 2022, RM 101 sold a certain property, including a warehouse, to a third party for $6.7 million gross with net sale proceeds of $6.2 million. The Definitive Agreement governing the sale included certain indemnifications which were subject to an $850,000 limitation and which expired in August 2023.

In August 2022, RM 101 sold (i) certain property, including a warehouse and a building which houses manufacturing, operations and administration, (ii) substantially all of its working capital and (iii) its historical business to a third party for $7.7 million gross, including net working capital, with net sale proceeds of $7.0 million. The Asset Purchase Agreement (the “APA”) governing the sale was structured as an asset sale. The APA included certain indemnifications which were subject to a $650,000 limitation and a related escrow of that amount upon consummation of the transaction. Substantially all the remaining purchase price was placed into escrow upon consummation of the transaction pending the completion of certain remaining environmental testing and remediation resulting therefrom, if any. At December 31, 2022, proceeds from this sale were included in restricted cash in the consolidated balance sheet. In February 2023, all escrowed funds were released to the Company.

In accordance with the CVR Agreement, as of September 30, 2023, the Company has made aggregate distributions of $9.6 million of proceeds to the CVR Holders. As of September 30, 2023, all RM 101 assets previously held for sale had been sold and the estimated remaining CVR liability of $1.4 million is included in contingent value rights in the consolidated balance sheet. The final CVR payment will be made on or about November 28, 2023.

Upon acquisition, the RM 101 business met the assets held-for-sale and discontinued operations criteria and is reflected as discontinued operations held for sale in these consolidated financial statements. The Company determined that the RM 101 business qualified as assets held for sale as management committed to a plan to sell the business, the business was in readily sellable form and it was deemed probable that the business would be sold in a twelve-month period. All net assets held for sale had been sold as of December 31, 2022. The loss from discontinued operations, net of tax presented in the consolidated statements of operations includes the following results of RM 101 (in thousands):

NOTE 4 – FAIR VALUE MEASUREMENTS

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-level fair value hierarchy prioritizing the inputs to valuation techniques is used to measure fair value. The levels are as follows: (Level 1) observable inputs such as quoted prices in active markets for identical assets or liabilities; (Level 2) observable inputs for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs other than quoted prices that are observable either directly or indirectly from market data; and (Level 3) unobservable inputs in which there is little or no market data, which require the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.

The following table illustrates the financial instruments measured at fair value on a non-recurring basis segregated by hierarchy fair value levels as of September 30, 2023 (in thousands):

	Carrying Value		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Other Unobservable Inputs (Level 3)		Remeasurement Gain (Loss)
Contingent consideration liability - Contingent Value Rights	$	1,366	$	—	$	1,366	$	—	$	(64)
	$	1,366	$	—	$	1,366	$	—	$	(64)

The following table illustrates the financial instruments measured at fair value on a non-recurring basis segregated by hierarchy fair value levels as of December 31, 2022 (in thousands):

	Carrying Value		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Other Unobservable Inputs (Level 3)		Remeasurement Gain (Loss)
Contingent consideration liability - Contingent Value Rights (1)	$	10,900	$	—	$	10,900	$	—	$	1,100
	$	10,900	$	—	$	10,900	$	—	$	1,100

(1)During the three months ended March 31, 2022, the Company changed the valuation approach from the use of other unobservable inputs to other observable inputs based on information obtained through the active marketing and sale of the underlying assets.

The Company has determined the long-term debt fair value as of September 30, 2023 is approximately $135.1 million (see Note 9). The carrying values of cash and cash equivalents, restricted cash, prepaid expenses, amounts due from related parties, other current assets, accounts payable, accrued construction liabilities, other accrued liabilities and other amounts due to related parties are considered to be representative of their respective fair values principally due to their short-term maturities. There were no additional material non-recurring fair value measurements as of September 30, 2023 and December 31, 2022, except for (i) the calculation of fair value of Common Stock warrants issued in connection with amendments to the Company’s long-term debt agreement (see Note 9), in connection with the issuance of Common Stock (see Note 15), in connection with a Common Stock exchange agreement (see Note 14) and on a standalone basis (see Note 14), (ii) the change in fair value of embedded derivatives in certain of the Company’s convertible promissory notes (see Note 14) and (iii) the calculation of fair value of nonmonetary assets distributed from the Company’s joint venture (see Note 11).

The Company utilized a Black-Scholes option pricing model and the application of a discount for lack of marketability (“DLOM”) to value its Common Stock warrants issued in connection with the New Term Facility and to value its Common Stock warrants issued in connection with the Fifth Amendment (each as defined in Note 9). The DLOM is applied primarily due to contractual restrictions on the exercise of the respective warrants. The estimated fair value of the warrants

20

TERAWULF INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

is determined using Level 3 inputs. Inherent in the model and fair value estimate are assumptions related to expected share-price volatility, expected life, risk-free interest rate, dividend yield and DLOM. The Company estimates volatility based on public company peer group volatility over the contractual term of the warrants. The risk-free interest rate is based on the U.S. Treasury rate on the grant date for a maturity similar to the expected life of the warrants, which is assumed to be equivalent to their contractual term. The dividend rate is based on the historical rate, which the Company anticipates will remain at zero. The Company applied a DLOM of 20% to value its Common Stock warrants issued in connection with the New Term Facility and applied a DLOM of 30% to value its Common Stock warrants issued in connection with the Fifth Amendment.

The Company capitalizes a portion of the interest on funds borrowed to finance its capital expenditures. Capitalized interest is recorded as part of an asset’s cost and is depreciated over the same period as the related asset. Capitalized interest costs were $0 and $2.2 million for the three and nine months ended September 30, 2023, respectively, and $1.9 million and $4.3 million for the three and nine months ended September 30, 2022, respectively.

Depreciation expense was $8.2 million and $20.1 million for the three and nine months ended September 30, 2023, respectively, and $1.5 million and $1.7 million for the three and nine months ended September 30, 2022, respectively.

NOTE 7 – LEASES

Effective in May 2021, the Company entered into a ground lease (the “Ground Lease”) related to the Lake Mariner Facility in New York with a counterparty which is a related party due to control by a member of Company management. The

21

TERAWULF INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Ground Lease includes fixed payments and contingent payments, including an annual escalation factor as well as the Company’s proportionate share of the landlord’s cost to own, operate and maintain the premises. The Ground Lease originally had an initial term of five years and a renewal term of five years at the option of the Company, subject to the Company not then being in default, as defined.

In July 2022, the Ground Lease was amended to increase the initial term of the lease to eight years and to amend certain other non-financial sections to adjust environmental obligations, site access rights and leasehold mortgage rights. In September 2022, the Company issued 8,510,638 shares with a fair value of $11.5 million as compensation to the landlord for entering into the lease amendment. The Ground Lease, which is classified as an operating lease, was remeasured as of the date of the amendment, resulting in an increase of $11.2 million to both right-of-use asset and operating lease liability in the consolidated balance sheets. The Ground Lease remained classified as an operating lease based on the remeasurement analysis that utilized a discount rate of 12.6%, which was an estimate of the Company’s incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at the remeasurement date. Upon expiration of the lease, the buildings and improvements on the premises will revert to the landlord in good order.

For the three and nine months ended September 30, 2023, the Company recorded operating lease expense of $0.3 million and $1.0 million, respectively, including contingent expense of $37,000 and $0.1 million, respectively, in operating expenses – related party in the consolidated statements of operations and made cash lease payments of $0.2 million and $0.8 million, respectively. For the three and nine months ended September 30, 2022, the Company recorded operating lease expense of $0.4 million and $0.5 million, respectively, including contingent expense of $0.1 million and $0.2 million, respectively, in operating expenses – related party in the consolidated statements of operations and made cash lease payments $0.1 million and of $0.2 million, respectively. The remaining lease term based on the terms of the amended Ground Lease as of September 30, 2023 is 10.6 years.

The following is a maturity analysis of the annual undiscounted cash flows of the estimated operating lease liabilities as of September 30, 2023 (in thousands):

During the nine months ended September 30, 2022, the Company entered into a short-term lease arrangement for digital currency miners. The term of the operating lease was two months and concluded in May 2022. There were no variable charges under this arrangement. For the three and nine months ended September 30, 2022, lease expense related to this arrangement of $0 and $1.3 million, respectively, was recorded in operating expenses in the consolidated statements of operations. The Company periodically enters into short term lease arrangements for operating equipment and recorded $0.1 million and $0.2 million under these short-term lease arrangements in operating expenses in the consolidated

statements of operations for the three and nine months ended September 30, 2023, respectively, and $0.3 million for each of the three and nine months ended September 30, 2022.

NOTE 8 – INCOME TAXES

The Company’s tax provision or benefit from income taxes for interim periods is determined using an estimate of the Company’s annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. The Company has an effective tax rate of 0.0% for each of the three and nine months ended September 30, 2023 and 0.54% for each of the three and nine months ended September 30, 2022. The Company’s effective rate differs from its statutory rate of 21% primarily due to the recording of a valuation allowance against its deferred tax assets. During the three and nine months ended September 30, 2022, the Company sold the net assets held for sale of IKONICS, resulting in a reversal of existing net deferred tax liabilities and a related tax benefit of $0.3 million recorded in income tax benefit in the consolidated statements of operations during each of the three and nine months ended September 30, 2022.

ASC 740 requires a valuation allowance to reduce the deferred tax assets reported if, based on the weight of available evidence, it is more likely than not that some or a portion or all the deferred tax assets will not be realized. As of September 30, 2023 and 2022, the Company estimated a portion of its deferred tax assets will be utilized to offset the Company’s deferred tax liabilities. Based upon the level of historical U.S. losses and future projections over the period in which the remaining deferred tax assets are deductible, at this time, management believes it is more likely than not that the Company will not realize the benefits of the remaining deductible temporary differences, and as a result the Company has recorded a valuation allowance as of September 30, 2023 and December 31, 2022 for the amount of deferred tax assets that will not be realized.

The Company has no unrecognized tax benefits as of September 30, 2023 and December 31, 2022. The Company’s policy is to recognize interest accrued and penalties related to unrecognized tax benefits in tax expense. No accrued interest or penalties were recorded during the three and nine months ended September 30, 2023 and 2022.

On December 1, 2021, the Company entered into a Loan, Guaranty and Security Agreement (the “LGSA”) with Wilmington Trust, National Association as administrative agent, which consisted of an original term loan facility of $123.5 million (the “Original Term Loan”). In July 2022, the Company entered into an amendment to the LGSA (the “First Amendment”) and borrowed $15.0 million at its closing (the “First Amendment Term Loan”). In October 2022, the Company entered into a third amendment to the LGSA (the “Third Amendment”) and borrowed $7.5 million at its closing (the “Third Amendment Term Loan” and, collectively with the Original Term Loan and First Amendment Term Loan, the “Term Loans”). The Term Loans bear an interest rate of 11.5% and have a maturity date of December 1, 2024. Upon the occurrence and during the continuance of an event of default, as defined, the applicable interest rate will be 13.5%. The interest rate may be increased, if applicable, to the cash interest rate on any junior capital raised plus 8.5%, if higher. As of September 30, 2023, no interest rate adjustments had been made under this provision. Subsequent to an amendment to the LGSA in March 2023 (the “Fifth Amendment,” as described below) and as of September 30, 2023, the Company is required to pay amounts subject to an excess cash flow sweep, as defined, on a quarterly basis which will automatically extend to the maturity of the Term Loans in the event the Company repays at least $40.0 million of the principal balance of the Term Loans by April 1, 2024. If the Company does not repay at least $40.0 million of the principal balance of the Term

23

TERAWULF INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Loans by April 1, 2024, the Company shall repay 25.0% of the outstanding principal balance in quarterly installments beginning on April 8, 2024 through the maturity date. Interest payments were due quarterly in arrears prior to the Fifth Amendment and are due monthly in arrears subsequent to the Fifth Amendment. The Company has the option to prepay all or any portion of the Term Loans in increments of at least $5.0 million subject to certain prepayment fees for the Original Term Loan equal to (1) if paid prior to December 1, 2023, an amount of 3% of the prepaid principal and (2) if paid subsequent to December 1, 2023 but prior to the maturity date of the Term Loans, an amount of 2% of the prepaid principal. Certain events, as described in the LGSA, require mandatory prepayment. The Term Loans are guaranteed by TeraWulf Inc. and TeraCub and its subsidiaries, as defined, and is collateralized by substantially all of the properties, rights and assets of TeraWulf Inc. and its subsidiaries (except RM 101), as defined.

The LGSA, as amended, requires the Company to maintain or meet certain affirmative, negative and reporting covenants. The affirmative covenants include, among other things, a requirement for the Company to maintain insurance coverage, maintain mining equipment and comply in all material respects with the Company’s Nautilus joint venture agreement (see Note 11), each as defined. The negative covenants restrict or limit the Company’s ability to, among other things, incur debt, create liens, divest or acquire assets, make restricted payments and permit the Company’s interest in the Nautilus joint venture to be reduced below 25%, each as defined. The LGSA also contains usual and customary events of default. If an event of default occurs and is continuing, the then outstanding obligations under the LGSA may become immediately due and payable.

As of September 30, 2023 and December 31, 2022, certain of the investors in the Term Loans were related parties due to cumulative voting control by members of the Company’s management and a member of the Company’s board of directors. As of September 30, 2023 and December 31, 2022, NovaWulf Digital Master Fund, L.P. and NovaWulf Digital Private Fund, LLC, held outstanding principal balances in the amount of $2.0 million and $15.7 million, respectively. In October 2023, all outstanding principal amounts held by NovaWulf Digital Master Fund, L.P. and NovaWulf Digital Private Fund, LLC were distributed to respective entities controlled by certain limited partners of NovaWulf Digital Master Fund, L.P. and all the members of NovaWulf Digital Private Fund, LLC., of which certain are members of Company management and a member of the Company's board of directors.

In connection with the Original Term Loan, the Company issued to the holders of the Original Term Loan 839,398 shares of Common Stock (the “Term Loan Equity”), which is a quantity of Common Stock which represented 1.5% of the outstanding shares of the publicly registered shares of TeraWulf subsequent to the closing of the Original Term Loan. In connection with the issuance of the Original Term Loan, the Company incurred aggregate issuance costs of approximately $4.0 million, in addition to a $1.2 million upfront fee. The aggregate issuance costs and the upfront fee were allocated to the Term Loan Equity and the Original Term Loan based on the relative fair value method in the amounts of $1.1 million and $4.1 million, respectively. For the Original Term Loan, this $4.1 million was included in debt discount along with the fair value of the Term Loan Equity, an amount of $25.7 million. The total of these items, an amount of $29.8 million, represented debt issuance costs and debt discount and was deducted from the Original Term Loan proceeds and was being accreted into the long-term debt balance over the term of the debt at an effective interest rate of 12.9%, which was in addition to the stated interest rate.

In July 2022, the First Amendment to the LGSA provided for an additional $50.0 million term loan facility (the “New Term Facility”). Pursuant to the New Term Facility, funds could have been drawn in three tranches. The First Amendment Term Loan represented the first tranche and was drawn at closing in July 2022, and the subsequent tranches of up to $35 million (the “Delayed Draw Term Loan Commitment”) may have been drawn at Company’s option prior to December 31, 2022, subject to certain conditions, including the raising of matching junior capital, as defined. The New Term Facility required the Company to extend the initial term of the Ground Lease from five years to eight years. In connection with the New Term Facility, the Company paid an upfront fee of $0.1 million and issued warrants to the lenders under the New Term Facility to purchase 5,787,732 shares of Common Stock at $0.01 per share, an aggregate number of shares of the Company’s Common Stock equal to 5.0% (comprised of 2.0% related to the Delayed Draw Term Loan Commitment and 3.0% related to the First Amendment Term Loan) of the then fully diluted equity of the Company. In connection with the issuance of the New Term Facility, the Company also incurred aggregate issuance costs of approximately $1.5 million, in addition to the aforementioned upfront fee. If the Company drew subsequent tranches, it was required to issue warrants to the lenders to purchase shares of the Company’s Common Stock equal to dilution of 3.75% upon the issuance of a second tranche in the amount of $15.0 million and 4.25% upon issuance of a third tranche in the amount of $20.0 million, in each case as a percentage of the then fully diluted equity of the Company, respectively.

The Company determined that debt modification accounting applied in connection with the New Term Facility. Third party and upfront fees were allocated pro rata between the First Amendment Term Loan and the Delayed Draw Term Loan

Commitment. Third-party fees of $0.4 million related to the First Amendment Term loan were expensed to interest expense in the consolidated statement of operations. Fees paid to lenders and the allocated value of the Common Stock warrants, an aggregate $3.5 million, related to the First Amendment Term Loan were included with the unamortized discount on the Original Term Loan and were being amortized as an adjustment of interest expense over the remaining term of the Term Loans at an effective rate of 13.1%, which was in addition to the stated interest rate.

Fees paid and the fair value of the Common Stock warrants related to the Delayed Draw Term Loan Commitment, an aggregate $3.4 million, were capitalized to other assets (the “Commitment Fee Asset”) and were amortized on a straight-line basis over the commitment period, which expired December 31, 2022. If a tranche of the Delayed Draw Term Loan Commitment was drawn, the then related carrying value of the Commitment Fee Asset was derecognized and a discount on debt was recorded and amortized over the term of the commitment drawn.

In October 2022, the Third Amendment to the LGSA divided the initial funding of up to $15.0 million of the Delayed Draw Term Loan Commitment under the First Amendment to the LGSA into two tranches of up to $7.5 million each. The Third Amendment Term Loan represented the first tranche and was borrowed upon the closing in October 2022. In connection with the Third Amendment, the Company entered into an amendment and restatement of the warrant agreement related to the New Term Facility. The amended and restated warrant agreement provides that holders thereto are entitled to additional warrants to purchase an aggregate number of shares of Common Stock equal to an incremental 3.75%, to be divided into two separate increments of 1.875% each, of the fully diluted equity of the Company, determined on the date of the funding of the two separate sub-tranches of $7.5 million each pursuant to the Third Amendment. In connection with the Third Amendment Term Loan, the Company issued warrants to purchase 2,667,678 shares of Common Stock at $0.01 per share. The fair value of the Common Stock warrants and the related proportional carrying value of the Commitment Fee Asset, an aggregate $2.9 million, related to Third Amendment were included with the unamortized discount on the Original Term Loan and First Amendment Term Loan and were being amortized as an adjustment of interest expense over the remaining term of the Term Loans at an effective rate of 25.1%, which was in addition to the stated interest rate.

In March 2023, the Fifth Amendment to the LGSA eliminated mandatory amortization of the Term Loans through April 7, 2024, as long as the Company received aggregate net proceeds of at least $33.5 million from the issuance of equity or equity-linked securities by March 15, 2023 (such condition, the “Amortization Relief Condition”). The Company satisfied the Amortization Relief Condition on March 9, 2023. As a condition of the Fifth Amendment becoming effective, the Company entered into a warrant agreement (the “Warrant Agreement”) to issue the following warrants to the lenders: (i) 27,759,265 warrants to purchase an aggregate number of shares of the Company’s Common Stock equal to 10.0% of the fully diluted equity of the Company as of the Fifth Amendment effective date with an exercise price of $0.01 per share of the Company’s Common Stock (the “Penny Warrants”) and (ii) 13,879,630 warrants to purchase an aggregate number of shares of the Company’s Common Stock equal to 5.0% of the fully diluted equity of the Company as of the Fifth Amendment effective date with an exercise price of $1.00 per share of the Company’s Common Stock (the “Dollar Warrants”). The quantity of the Penny Warrants and the Dollar Warrants include the final impact of anti-dilution protection for additional capital raising transactions by the Company of up to $5.0 million subsequent to the $33.5 million aggregate net proceeds associated with the Amortization Relief Condition. The Penny Warrants are exercisable during the period beginning on April 1, 2024 and ending on December 31, 2025, and the Dollar Warrants are exercisable during the period beginning on April 1, 2024 and ending on December 31, 2026. In March 2023, in connection with the issuance of the warrants pursuant to the Warrant Agreement, the Company entered into a registration rights agreement pursuant to which the Company has agreed to provide customary shelf and piggyback registration rights to the LGSA lenders with respect to the common stock issuable upon exercise of the warrants described above.

The Company determined that debt modification accounting applied in connection with the Fifth Amendment. Because the First Amendment and the Fifth Amendment occurred within a twelve-month period, the debt terms that existed just prior to the First Amendment were applied in determining the appropriateness of the debt modification accounting model. The allocated value of the Penny Warrants and Dollar Warrants, an aggregate $16.0 million, related to the Fifth Amendment were included with the unamortized discount on the LGSA, as amended, and are being amortized as an adjustment of interest expense over the remaining term of the modified LGSA at an effective rate of 19.7%, which is in addition to the stated interest rate.

During the three and nine months ended September 30, 2023, the Company amortized total debt issuance costs and debt discount of $6.0 million and $16.0 million, respectively, of which $6.0 million and $14.3 million, respectively, were recorded as interest expense in the consolidated statements of operations, $0 and $1.2 million, respectively, were capitalized interest in property, plant and equipment, net in the consolidated balance sheets as of September 30, 2023 and

NOTE 10 – STANDBY EQUITY PURCHASE AGREEMENT AND CONVERTIBLE PROMISSORY NOTE

Standby Equity Purchase Agreement

In June 2022, the Company entered into a Standby Equity Purchase Agreement (“SEPA”) with YA II PN, Ltd. (“Yorkville”). Pursuant to the SEPA, the Company had the right, but not the obligation, to sell to Yorkville, subject to certain limitations and conditions, up to $50.0 million of its shares of Common Stock, at the Company’s request any time during the commitment period commencing on June 2, 2022 and terminating on the earliest of (i) the first day of the month following the 36-month anniversary of the SEPA and (ii) the date on which Yorkville shall have made payment of any advances requested pursuant to the SEPA for shares of the Common Stock equal to the commitment amount of $50.0 million. In addition to the Company’s right to request advances, subject to certain conditions precedent, the Company had the option to, but was not obligated to, effect a pre-advance loan with a principal amount of $15.0 million through the issuance and sale to Yorkville of a convertible promissory note (the “Promissory Note”). The Company elected to issue and sell the Promissory Note to Yorkville on June 2, 2022. Subject to the terms of the SEPA, the Company had the right to terminate the SEPA at any time, at no cost or penalty, upon five trading days’ prior written notice so long as there are no outstanding advances, no outstanding balance on the Promissory Note and no other amounts owed to Yorkville. No termination of the SEPA affects the indemnification provisions contained within the SEPA, which provisions survive a termination. The SEPA was terminated in December 2022. No advances occurred while the SEPA was outstanding.

Yorkville Convertible Promissory Note

In June 2022, the Company issued the Promissory Note to Yorkville, which was issued with a 2.0% original issue discount, for proceeds of $14.7 million. The maturity date of the $15.0 million Promissory Note was originally November 25, 2022 and the Company was required to pay the outstanding principal balance in five monthly $3.0 million payments commencing July 27, 2022. Upon reasonable advance notice, the Company had the right to defer 50% of a monthly payment amount due on two such monthly payments to later dates to be mutually agreed by the Company and Yorkville. In July 2022, $1.5 million of the $3.0 million July monthly payment amount was deferred until the October 2022 monthly payment due date. In August 2022, $1.5 million of the $3.0 million August monthly payment amount was deferred until the November 2022 monthly payment due date. The Promissory Note, which bore an interest rate of 4.0% and had an initial conversion price of $3.75 per share of Common Stock, may have been repaid with the proceeds of a sale of Common Stock to Yorkville or repaid in cash and, if repaid in cash, together with a cash payment premium originally of 6.0%, provided that if the Company’s Common Stock market price, as defined, was less than $2.25 per share, the cash payment premium would have been 4.0%. In October and November 2022, the Company amended and restated the Promissory Note to, among other things, change the then-existing repayment schedule, change the cash payment premium to 12.0% and change the conversion price. The Company determined that extinguishment of debt accounting applied to the October 2022 amendment and restatement because the change in the fair value of the embedded conversion feature was greater than 10% of the carrying value of the Promissory Note immediately prior to the modification. The Company recorded a loss on debt extinguishment of $2.1 million in the consolidated statement of operations for the year ended December 31, 2022. This extinguishment loss was primarily related to the change in the fair value of the embedded conversion feature of $1.6 million and the excess of the fair value of the A&R Promissory Note of $9.4 million over the carrying value of the Promissory Note immediately prior to the modification. The Company determined that debt modification accounting applied to the November 2022 amendment and restatement. The $20,000 change in the fair value of the embedded conversion feature was accounted for as a debt discount and amortized as an adjustment of interest expense over the remaining term of the Second A&R Promissory Note at an effective rate of 3.1%. No portion of the Second A&R

Promissory Note was converted into shares of Common Stock and the Second A&R Promissory Note was paid in full in December 2022.

Convertible Promissory Notes

In November 2022, the Company issued convertible promissory notes (the “Convertible Notes”) in an aggregate principal amount of approximately $3.4 million to certain accredited investors, including to members of Company management in the amount of $1.7 million. The Convertible Notes were issued in privately negotiated transactions as part of a private placement exempt from registration under the Securities Act of 1933, as amended. The Convertible Notes, which contained usual and customary antidilution provisions, had a maturity date of April 1, 2025 and accrued annual interest at a rate of 4%, which would have increased to 15% upon the occurrence of an event of default, as defined. The Convertible Notes were originally automatically convertible into shares of equity securities of the Company upon the closing of a Qualified Financing, as defined in the Convertible Notes as the issuance and sale of equity securities with an aggregate gross sales price of not less than $5.0 million, with certain sales of equity securities excluded, at a conversion price equal to the price per share paid by the investors purchasing such equity securities in such Qualified Financing. The Convertible Notes originally embodied an unconditional obligation to settle a fixed monetary amount with, upon a Qualified Financing, with a variable number of shares and was initially considered potentially share settled debt. In December 2022, the Company entered into a private placement (see Note 14) which met the definition of a Qualified Financing and contemporaneously amended the Convertible Notes to (a) change the conversion date to March 1, 2023 and (b) allow for the conversion price to be reduced if an additional Qualified Financing were to occur prior to the conversion date at a price lower than the then existing Convertible Note conversion price. The Company determined that debt modification accounting applied in connection with the December 12, 2022 amendment to the Convertible Notes. There was no change to the effective interest rate as the result of this amendment. As a result of the private placement, the conversion price was $0.40 per share of Common Stock. The Convertible Notes are included in convertible promissory notes in the consolidated balance sheet as of December 31, 2022. In January 2023, the Convertible Notes were amended to change the conversion date to the third business day following the Shareholder Approval Date (as defined in Note 14). In March 2023, the Convertible Notes and accrued but unpaid interest were converted into 8,628,024 shares of Common Stock.

In January 2023, the Company entered into a convertible promissory note (the “January Convertible Note”) to an accredited investor in a privately negotiated transaction as part of a private placement exempt from registration under Section 4(a)(2) and/or Regulation D under the Securities Act in an aggregate principal amount of $1.3 million. The January Convertible Note had a maturity date of April 1, 2025 and accrued annual interest at a rate of 4.0%. The January Convertible Note was automatically convertible into Common Stock on the third business day following the Shareholder Approval Date (the “Conversion Date”) at a conversion price equal to the lowest price per share paid by investors purchasing equity securities in any sale of equity securities by the Company between November 25, 2022 and the Conversion Date with an aggregate gross sales price of not less than $5 million, subject to certain exclusions set forth in the January Convertible Note. The conversion price was $0.40 per share of Common Stock upon issuance. In March 2023, the January Convertible Note and accrued but unpaid interest were converted into 3,134,932 shares of Common Stock.

NOTE 11 – JOINT VENTURE

In May 2021, the Company and a subsidiary of Talen Energy Corporation (“Talen”) (each a “Member” and collectively the “Members”) entered into a joint venture, Nautilus Cryptomine LLC (“Nautilus”), to develop, construct and operate up to 300 MW of zero-carbon bitcoin mining in Pennsylvania (the “Joint Venture”). In connection with the Joint Venture, Nautilus simultaneously entered into (i) a ground lease (the “Nautilus Ground Lease”), which includes an electricity supply component, with a related party of Talen, (ii) a Facility Operations Agreement (the “FOA”) with a related party of the Company and (3) a Corporate Services Agreement (the “CSA”) with a related party of Talen. Each Member originally held a 50% interest in the Joint Venture. The Company capitalized a portion of the interest on funds borrowed to finance its investments in Nautilus prior to Nautilus commencing its principal operations. Capitalized interest costs were $0 and $0.9 million for the three and nine months ended September 30, 2023, respectively, and $0 and $1.6 million for the three and nine months ended September 30, 2022, respectively. During the nine months ended September 30, 2023, the Company received bitcoin distributions from Nautilus with a fair value of $11.7 million. The Company received no bitcoin distributions in 2022.

In August 2022, the Members entered into an amended and restated Joint Venture agreement (the “A&R Agreement”) whereby, among other changes, the unit ownership will be determined by infrastructure contributions while distributions of mined bitcoin will be determined by each Member’s respective hashrate contributions. Members are allowed to make contributions of miners up to the effective electrical capacity of their owned infrastructure percentage. Each party retains

27

TERAWULF INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

access to 50% of the electricity supply outlined in the Nautilus Ground Lease. Additionally, the Company’s scheduled capital contributions were amended such that the Company would retain a 33% ownership interest in the Joint Venture if such capital contributions were funded. With the change in ownership percentage, governance rights were amended to provide for greater Talen board participation, among other changes. As allowed under the A&R Agreement, the Company structured its capital contributions to achieve a targeted a 25% ownership interest in Nautilus.

In March 2023, the Company entered into a second amended and restated limited liability company agreement for Nautilus (the “Second A&R Nautilus Agreement”). Under the Second A&R Nautilus Agreement, the Company holds a 25% equity interest in Nautilus and Talen holds a 75% equity interest in Nautilus, each subject to adjustment based on relative capital contributions. Distributions are made periodically in accordance with each Member’s respective hashrate contributions after deducting primarily each Member’s share of power and operational costs. Pursuant to the terms of the Second A&R Nautilus Agreement, the Nautilus Cryptomine Facility initially requires 200 MW of electric capacity. Prior to May 13, 2024, the Company may elect to expand the energy requirement of the Nautilus Cryptomine Facility by up to 50 MW, funded solely by the Company. If the Company makes such an election, the Talen Member may, within twelve months thereof, elect to expand the energy requirement of the Nautilus Cryptomine Facility by up to an additional 50 MW, funded solely by the Talen Member, for a total capacity of up to 300 MW. Upon such election, Nautilus will call additional capital for expansion and enter into an additional energy supply agreement with Talen Member or its affiliate for the additional capacity, subject to any regulatory approvals and third-party consents.

In March 2021, TeraCub executed an agreement for the purchase of bitcoin miners from MinerVA Semiconductor Corp. (“MinerVA”) for a total of 30,000 MV7 miners, with originally scheduled monthly deliveries of miners each between November 2021 and January 2022, for an aggregate price of $118.5 million (the “MinerVA Purchase Agreement”). Concurrently with the execution of the Joint Venture agreement, TeraWulf assigned the MinerVA Purchase Agreement to Nautilus. Prior to December 31, 2022, total payments of $40.5 million were made under the MinerVA Purchase Agreement. Production delays at MinerVA’s factory impacted the initial pricing and delivery schedule. Accordingly, Nautilus and MinerVA have deemed all payments made to date to apply to the initial approximate 9,000 miners shipped or to be shipped. As of the date at which these financial statements were available to be issued, Nautilus had not amended the MinerVA Purchase Agreement.

In June 2021, Nautilus entered into two Non-fixed Price Sales and Purchase Agreements for the purchase of bitcoin miners from Bitmain Technologies Limited (“Bitmain”) for a total of 30,000 S19j Pro miners, with originally scheduled monthly deliveries of 5,000 miners each between January 2022 and March 2022 under one agreement (the “Q1 2022 Bitmain Agreement’) and 5,000 miners each between April 2022 and September 2022 under a second agreement (the “Q2 2022 Bitmain Agreement” and, together, the “Bitmain Purchase Agreements”). During the nine months ended September 30, 2022, the Company paid Bitmain $22.8 million and was reimbursed by Talen for 50% of that amount. As of December 31, 2022, the Q1 2022 Bitmain Agreement was concluded with all parties performing under the contract. In September 2022, the Q2 2022 Bitmain Agreement was cancelled whereby each Member received a $31.2 million credit with Bitmain to use at the respective Member’s discretion (the “Bitmain Credit”). See Note 12. The Company recorded a distribution from the Joint Venture whereby equity in net assets of investee was reduced and property, plant and equipment, net was correspondingly increased by the $31.2 million distributed credit in the consolidated balance sheet as of December 31, 2022.

In December 2022, the Company entered into a Payment Netting Agreement with Nautilus, Talen and the related party FOA and CSA agreement counterparties whereby certain amounts were owed by Nautilus to each of the FOA and CSA counterparties, including for the termination of the FOA agreement. These amounts were offset to arrive at a net result whereby the Company owed the related party FOA counterparty (see Note 16) approximately $2.2 million. This amount is recorded in equity in net assets of investee in the consolidated balance sheet as of December 31, 2022.

The Company’s direct payments to MinerVA and Bitmain, among others, on behalf of Nautilus for the nine months ended September 30, 2022, are included in investments in joint venture related to direct payments made on behalf of joint venture

Nautilus is a VIE accounted for using the equity method of accounting. The table below summarizes the Company’s interest in Nautilus and the Company’s maximum exposure to loss as a result of its involvement with the VIE as of September 30, 2023 (in thousands, except for percentages):

	%		Initial Investment		Additional Investment, Net		Net loss Inception to Date		Company’s Variable Interest in Entity		Commitment to Future Additional Contributions (1)		Company’s Maximum Exposure to Loss in Entity (2)

(1)The Members may mutually agree on changes to the Nautilus facility, which could increase the amount of contributions the Company is required to provide. The Members may seek alternate financing for the Nautilus facility, which could reduce the amount of investments each Member may be required to provide.

(2)The maximum exposure at September 30, 2023 is determined by adding the Company’s variable interest in the entity and any explicit or implicit arrangements that could require the Company to provide additional financial support. The amount represents the contractually required capital contributions of the Company which were required for the initial phase of the Nautilus facility buildout.

Due to the change in Member ownership percentage and governance rights under the A&R Agreement, Talen determined it controlled the Joint Venture from an accounting perspective and thereby was required to fair value the identifiable assets and liabilities of the Joint Venture for its internal accounting purposes. Under the CSA, Talen is responsible for maintaining the books and records of the Joint Venture and elected to push down the fair value adjustments to Nautilus’ books and records. During the nine months ended September 30, 2023, Talen elected to push down an additional fair value adjustment to Nautilus’ books and records. The Company accounts for the Joint Venture as an equity method investment and the change in ownership percentage does not impact the Company’s method of accounting or basis. Therefore, there is a basis difference between the books and records of Nautilus and the Company’s accounting basis in the Joint Venture. The

(1)The condensed statement of operations information for the three and nine months ended September 30, 2023 and 2022 and the condensed balance sheet information as of September 30, 2023 and December 31, 2022 reflect the impact of the Talen-estimated fair value measurements of Nautilus which, resulting from the application of ASC 805 “Business Combinations,” have been pushed down to the books and records of Nautilus by Talen, as discussed above. The Company’s basis in the assets and liabilities of Nautilus continue to be recorded at historical value on the accompanying consolidated balance sheets.

In March 2022, the Company entered into an exchange agreement with Nautilus and the Nautilus co-venturer whereby the Company purchased 2,469 of Nautilus’ Bitmain S19j Pro miners (the “Nautilus Miners”) to be received under the Bitmain Purchase Agreements in exchange for an option to either (1) deliver miners that are not less favorable in all material respects to those of the Nautilus Miners (the “Exchange Miners”) by July 1, 2022 or (2) incur a pro forma adjustment to Nautilus’ distributions such that the Nautilus co-venturer is made whole as though the miners had not been transferred to the Company. If the Exchange Miners were not delivered by September 30, 2022, the Nautilus co-venturer would have been entitled to elect to distribute in-kind a number of miners then in possession of Nautilus comparable to the then-undelivered Exchange Miners. During the nine months ended September 30, 2022, the Nautilus Miners were received and recorded at fair value to property, plant and equipment, net in the amount of $16.0 million with a corresponding recognition of an exchange miner liability of the same amount. The A&R Agreement removed the Company’s obligation to deliver the Exchange Miners to the Joint Venture. Accordingly, the Company derecognized the miner exchange liability and recorded a $16.8 million reduction in equity in net assets of investee in the consolidated balance sheet as of December 31, 2022 and recorded a loss on nonmonetary miner exchange of $0.8 million in the consolidated statement of operations for the three and nine months ended September 30, 2022.

In September 2022, the Company, as allowed under the A&R Agreement and because its Lake Mariner Facility was operational, transferred 2,500 Bitmain S19j Pro miners from Nautilus to its Lake Mariner Facility. Accordingly, the Company recorded the miners at an estimated fair value of $4.8 million, determined based on a contemporaneous observed market price for identical assets, in property, plant and equipment, net and the Company reduced the equity in net assets of investee balance by $16.3 million, the book value of the miners in Nautilus’ books and records, in the consolidated balance sheet as of December 31, 2022 and recorded a loss of $11.5 million as a component of equity in net loss of investee, net of tax in the consolidated statements of operations for the three and nine months ended September 30, 2022.

Accordingly, the Company recorded the miners at an estimated fair value of $6.9 million, determined based on a contemporaneous observed market price for similar assets, in property, plant and equipment, net and the Company reduced the equity in net assets of investee balance by $20.5 million, the book value of the miners in Nautilus’ books and records, in the consolidated balance sheet as of September 30, 2023 and recorded a loss of $0 and $13.6 million as a component of equity in net loss of investee, net of tax in the consolidated statements of operations for the three and nine months ended September 30, 2023, respectively.

If applicable, such payments will be made concurrently with the dividend or distribution to the holders of the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Company’s Common Stock. Upon liquidation, the Convertible Preferred Stock will rank senior to the Company’s Common Stock, and will have the right to be paid, out of the assets of the Company legally available for distribution to its stockholders, an amount equal to the Liquidation Preference (as defined in the Company’s Series A Convertible Preferred Certificate of Designations) per share of the Convertible Preferred Stock.

The number of shares of Common Stock issuable upon conversion will be equal to the liquidation preference, including accumulated and unpaid dividends, divided by the Conversion Price, as defined. The Conversion Price is determined by dividing $1,000 by the Conversion Rate, as defined, which is initially 100 shares of Common Stock per $1,000 liquidation preference of Convertible Preferred Stock. The Conversion Rate will be adjusted for certain customary events, including (but not limited to) stock dividends, stock splits or combinations, tender offers or exchange offers and, additionally, for Fundamental Changes, as defined, to include (but are not limited to) a change in control of the Company, disposition of substantially all assets of the Company, the Company’s Common Stock holders approve a plan of liquidation or dissolution or the Company’s Common Stock cease to be listed on the Nasdaq Capital Market.

If any Convertible Preferred Stock is to be converted pursuant to a Holder’s optional conversion, the Company will have the option to settle such conversion in cash, as defined.

Overview

We are a digital asset technology company with a core business of digital infrastructure and energy development to enable sustainable bitcoin mining. TeraWulf’s principal business consists of developing and operating bitcoin mining facilities in the United States that are fueled by clean, low cost and reliable power sources. The Company's fully integrated bitcoin mining facilities in the United States use nuclear, hydro and solar energy sources, and currently consume over 91% zero-carbon energy to produce bitcoin, with the mission of utilizing 100% zero-carbon energy. TeraWulf began trading on Nasdaq under the symbol “WULF” on December 14, 2021, following its successful strategic business combination with RM 101 Inc. (formerly known as IKONICS Corporation).

Bitcoin Mining

Bitcoin was introduced in 2008 with the goal of serving as a digital means of exchanging and storing value. Bitcoin is a form of digital currency that depends upon a consensus-based network and a public ledger called a “blockchain,” which contains a record of every bitcoin transaction ever processed. The bitcoin network (the "Bitcoin Network") is the first decentralized peer-to-peer payment network, powered by users participating in the consensus protocol, with no central authority or middlemen, that has wide network participation. The authenticity of each bitcoin transaction is protected through digital signatures that correspond with addresses of users that send and receive bitcoin. Users have full control over remitting bitcoin from their own sending addresses. All transactions on the bitcoin blockchain are transparent, allowing those running the appropriate software to confirm the validity of each transaction.

To be recorded on the blockchain, each bitcoin transaction is validated through a proof-of-work consensus method, which entails solving complex mathematical problems (the “hash riddle”) to validate transactions and post them on the blockchain. This process is called mining. Bitcoin miners are the work horses of the Bitcoin Network. Miners are rewarded with bitcoins, both in the form of newly-created bitcoins and fees in bitcoin, for successfully validating transactions (a block) by solving the mathematical problems and providing hash computation services to the network and maintaining the bitcoin ledger. Factors such as access to computer processing capacity, interconnectivity, electricity cost, environmental factors (such as cooling capacity) and location play important roles in mining.

Bitcoin miners, such as TeraWulf, invest in a computation network (mining rigs with application-specific integrated circuit ("ASIC") chips) and purchase power to probabilistically win the right to validate blocks, and earn bitcoin in return, either through the direct participation on the Bitcoin Network or through participation in a mining pool. The bitcoin reward schedule to the miners represents the supply curve of bitcoin. Bitcoin is a unique commodity with an inelastic supply curve because only 21 million fixed bitcoin can be mined until the year 2140 of which approximately 19.5 million bitcoin have been issued thus far. In addition, the bitcoin reward issued to miners is cut by half every 4 years, which is commonly referred to as the “halving” event. The halving is a software nuance in bitcoin’s code that reduces the block reward by 50% after every 210,000 blocks are validated/mined. The first bitcoin block was mined January 3, 2009, and block rewards have declined from 50 bitcoin per block at inception to 6.25 bitcoin per block today, which is expected to decline to 3.125 in or around April 2024, the next anticipated halving date.

Our two bitcoin mining facilities participate in a mining pool operated by Foundry Digital LLC. As of September 30, 2023, our operating mining units are currently producing an average of approximately 5.0 exahash per second (“EH/s") of hashrate. In bitcoin mining, “hashrate” is a measure of the computing and processing power and speed by which a mining computer mines and processes transactions on the Bitcoin Network. “Network hashrate” is the total hashrate dedicated to solving the hash riddle. If more miners enter the network, the hashrate increases; higher hashrate means faster riddle resolutions, for a given difficulty level. The bitcoin protocol automatically adjusts the difficulty level higher or lower every 2,016 blocks or approximately every two weeks, which keeps the system in equilibrium with a new block being mined every ten minutes. We are actively expanding our bitcoin mining business and expect to continue

40

increasing our hashrate through 2024 and beyond as we expand our infrastructure at our wholly owned and operated Lake Mariner Facility in the State of New York (the “Lake Mariner Facility”), and seek strategic acquisition targets.

A company’s hashrate is generally considered to be one of the most important metrics for evaluating bitcoin mining companies. We obtain bitcoin as a result of our mining operations, and we sell bitcoin on a daily, weekly, and monthly basis to support our operations and strategic growth. We do not currently plan to engage in regular trading of bitcoin (other than as necessary to convert our bitcoin to U.S. dollars) or to engage in hedging activities related to our holding of bitcoin; however, our decisions to hold or sell bitcoin at any given moment in time may be impacted by the bitcoin market, which has been historically characterized by significant volatility. We do not hold, sell or transact in bitcoin or any other digital assets for anyone other than ourselves.

TeraWulf Bitcoin Mining Operations

TeraWulf commenced industrial scale bitcoin mining in March 2022 and is currently mining bitcoin and utilizing predominantly zero-carbon energy resources at two data centers: the Lake Mariner Facility located in upstate New York and the jointly owned Nautilus Cryptomine facility located in central Pennsylvania (the “Nautilus Cryptomine Facility”). As of September 30, 2023, these two industrial scale projects had a combined operating capacity of 5.5 EH/s with approximately 50,000 miners deployed, comprised of 34,000 operational miners at the Lake Mariner Facility (including 5,000 hosted miners) and 16,000 self-miners at the Nautilus Cryptomine Facility.

The Lake Mariner Facility

Located at a site adjacent to the now decommissioned coal-fired power plant in Barker, New York, the Lake Mariner Facility began sustainably mining bitcoin in March 2022. As of the date of this Quarterly Report, the Lake Mariner Facility is operating approximately 110 megawatt ("MW") of bitcoin mining capacity comprised of two approximately 50 MW buildings and approximately 10 MW located on the turbine deck of the former coal plant. As recently announced, the Company is currently expanding its Lake Mariner Facility with the addition of a third building, which will house an incremental 43 MW of bitcoin mining capacity. The Company has an agreement in place with the Power Authority of the State of New York for 90 MW of energy to support its bitcoin mining operations, and the Lake Mariner Facility has the ability to scale up to 500 MW of bitcoin mining capacity.

As of September 30, 2023, we own approximately 30,000 miners of which approximately 29,000 are operational at the Lake Mariner Facility and the remainder undergoing maintenance or on standby to replace miners under repair, excluding the 5,000 hosted miners. Our miners are primarily comprised of Bitmain Antminer S19 series. Our fleet of miners range in age from 0.2 to 1.3 years and have an average age of approximately 0.6 years. We do not have scheduled downtime for our miners; however, while we periodically perform unscheduled maintenance on our miners, such downtime has not been significant historically. When performing unscheduled maintenance, depending on the length of estimated repair time, we may replace a miner with a substitute miner to limit overall downtime. Our fleet of miners at the Lake Mariner Facility has a range of energy efficiency from 22 to 39 joules per terahash ("j/th") and has an average energy efficiency of 28.8 j/th.

The majority of our revenue comes from our self-mined bitcoin, which we store and safeguard in a cold storage wallet held by our custodian, NYDIG Trust Company LLC, a duly chartered New York limited liability trust company.

The Nautilus Cryptomine Facility

Located in Berwick, Pennsylvania, Nautilus Cryptomine LLC (“Nautilus”) is a joint venture between TeraWulf and a subsidiary of Talen Energy Corporation (“Talen”). Nautilus currently owns a 200 MW bitcoin mining facility located adjacent to the 2.5 gigawatt ("GW") nuclear-powered Susquehanna Station, 2.3 GW of which are owned and operated by Talen. The Nautilus Cryptomine Facility represents the first bitcoin mining facility site that is powered by 100% “behind the meter” zero-carbon nuclear energy, which is contracted at a fixed rate of 2.0 cents per kilowatt hour ("kWh") for a term of five years with two successive three-year renewal options. Under the Nautilus joint venture agreement, the Company holds a 25% equity interest in Nautilus and Talen holds a 75% equity interest, each subject to adjustment based on relative capital contributions. TeraWulf began mining bitcoin at the Nautilus Cryptomine Facility in the first quarter of 2023 and, as of the date of this Quarterly Report, has an allotted 50 MW of bitcoin mining capacity at the Nautilus Cryptomine Facility. Prior to May 13, 2024, the Company has an option to increase its energy requirement at the Nautilus Cryptomine Facility by an incremental 50 MW at its own cost (for a total of 100 MW of bitcoin mining capacity attributable to TeraWulf). If the Company makes such an election, Talen may, within twelve months thereof, also elect to expand the energy requirement at the Nautilus Cryptomine Facility by up to an additional 50 MW, funded solely by Talen, for a total capacity of up to 300 MW at the Nautilus Cryptomine Facility. Upon such election, Nautilus will enter into an additional energy

41

supply agreement with Talen or its affiliate for the additional capacity, subject to any regulatory approvals and third-party consents.

As of September 30, 2023, approximately 16,000 miners have been deployed at the Nautilus Cryptomine Facility relative to TeraWulf's contributions to Nautilus in order to utilize TeraWulf's allotted 50 MW of bitcoin mining capacity. These miners are Bitmain Antminer S19 series, range in age from 0.5 to 0.7 years and have an average age of approximately 0.6 years. These miners have a range of energy efficiency from 22 to 30 j/th and an average energy efficiency of 25.5 j/th. While the Company holds a 25% equity interest in Nautilus, the distributions of mined bitcoin are determined by each of TeraWulf’s and Talen’s respective hashrate contributions. Accordingly, the Company has contributed approximately 1.9 EH/s of a total 5.2 EH/s of miners which results in an approximate 35.7% of the hashrate share attributed to the Company.

As described above, there are a variety of factors that influence our ability to mine bitcoin profitably, including bitcoin’s value in USD, mining difficulty global hashrate, power prices, fleet energy efficiency, data center energy efficiency and other factors. The energy efficiency of a mining fleet helps drive profitability, because the most significant direct expense for bitcoin mining is power. We measure efficiency by the joules of energy required to produce each terahash of processing power (“j/th”). We believe we operate a highly efficient fleet of miners. The Company uses the following metrics as indicators of operational progress and effectiveness and believes they are useful to investors for the same purposes and to provide comparisons to peer companies.

The table below describes our fleet as of September 30, 2023 and describes our miner efficiency and computing power as compared to the global computing power.

Combined facilities1	As of September 30, 2023
Global hashrate (EH/s)2	391.8
Miner efficiency (j/th)3	27.6
TeraWulf combined average operating hashrate (EH/s)4	5.0
TeraWulf % of Global hashrate	1.3	%

1 Results reflect hashrate of mining operations at the Lake Mariner facility and TeraWulf’s net share of hashrate produced at the Nautilus facility.

2 Total global hashrate obtained from YCHARTS (https://ycharts.com/indicators/bitcoin_network_hash_rate)

3 Joules of energy required to produce each terahash of processing power

4 While nameplate inventory for WULF’s two facilities is 5.5 EH/s, inclusive of gross total hosted miners, actual monthly hashrate performance depends on a variety of factors, including (but not limited to) performance tuning to increase efficiency and maximize margin, scheduled outages (scopes to improve reliability or performance), unscheduled outages, curtailment due to participation in various cash generating demand response programs, derate of ASICS due to adverse weather and ASIC maintenance and repair.

As of September 30, 2023 our operating hashrate was approximately 1.3% of the total global hashrate, and we received approximately the same percentage of the global blockchain rewards, which as of that date, equaled approximately 10 to 13 bitcoin per day. Ultimately, in order to mine profitably, we work to ensure that these mining rewards cover our direct operating costs.

1Bitcoin mining revenue represents revenue generated by providing hash computation services to a mining pool and excludes revenue from data center hosting arrangements.

Power prices are the most significant cost driver for our wholly owned locations, and energy costs represented 39.5% and 35.3% as expressed as a percentage of bitcoin mining revenues during the three and nine months ended September 30, 2023, respectively.

Energy prices can be highly volatile and global events (including the war in Ukraine and the resulting natural gas shortage) have caused power prices to increase nationwide over the past year. Our wholly-owned Lake Mariner Facility in New York is subject to variable prices and market rate fluctuations with respect to wholesale power costs. Such prices are governed by market power prices and said prices can change hour to hour. While this renders energy prices less predictable, it also gives us greater ability and flexibility to actively manage the energy we consume with an eye towards increasing profitability and energy efficiency. Energy prices are also highly sensitive to weather events, such as winter storms and polar vortices, which increase the demand for power regionally. When such events occur, we may curtail our operations to avoid using power at increased rates or we may be curtailed under demand response programs in which we participate. The average power prices we paid at Lake Mariner during each of the three and nine months ended September 30, 2023 was $0.036 per kilowatt hour.

The management team makes real-time determinations on the need and timing during which we should curtail. If not otherwise curtailed under demand response programs, we curtail when power prices exceed the value we would receive for the corresponding fixed bitcoin reward. This means if bitcoin’s value decrease or energy prices increase, our curtailment will increase; likewise, when bitcoin’s value increases and energy prices decrease, our curtailment will decrease. The management team manages this decision on an hour-by-hour basis.

During the three and nine months ended September 30, 2023, the Company curtailed operations at Lake Mariner due to weather events, energy price spikes, and demand response program participation, and recorded expected payments to be received for demand response programs as a reduction in cost of revenue; the amount of aggregate expected payments to be received were $1.7 million and $2.5 million for the three and nine months ended September 30, 2023, respectively.

Recent Developments

Bitmain Purchase Agreement - S19j XP

On July 14, 2023, TeraLease LLC (“TeraLease”), a subsidiary of the Company, entered into a future sales and purchase agreement with Bitmain Technologies Delaware Limited (“Bitmain Delaware”). The agreement provides that

43

TeraLease will receive 15,138 S19j XP miners from Bitmain Delaware, with an option to receive an additional 3,362 miners if the TeraLease meets its payment obligations under the agreement, for delivery in Q4 2023 for a total purchase price of $75.4 million, 30% of which TeraLease is entitled to apply paid-for coupons, resulting in an effective purchase price of $53.4 million for 18,500 miners. TeraWulf plans to use the new miners to expand mining capacity at its Lake Mariner Facility.

Amendment to ATM Sales Agreement

On April 26, 2022, TeraWulf entered into an at-the-market sales agreement (the “ATM Sales Agreement”) with Cantor Fitzgerald & Co. (“Cantor”), B. Riley Securities, Inc. (“B. Riley”) and D.A. Davidson & Co. (“D.A. Davidson”), pursuant to which the Company may offer and sell, from time to time, through or to the agents, shares of the Company’s common stock, par value $0.001 per share (the “Shares”), having an aggregate gross sales price of up to $200.0 million (the “ATM Program”). On August 7, 2023, TeraWulf and D.A. Davidson mutually agreed that D.A. Davidson would no longer participate as a sales agent under the ATM Program. On August 11, 2023, the Company entered into an amendment to the Sales Agreement with Cantor, B. Riley, Northland Securities, Inc. (“Northland”) and Compass Point Research & Trading, LLC (“Compass Point”; Cantor, B. Riley, Northland and Compass Point, collectively, the“Agents”) to the ATM Sales Agreement.

The Company is not obligated to sell any Shares under the ATM Program. Subject to the terms and conditions of the Sales Agreement, the Agents will use commercially reasonable efforts, consistent with their normal trading and sales practices, to sell Shares from time to time based upon the Company’s instructions, including any price, time or size limits or other customary parameters or conditions specified by the Company. Under the ATM Sales Agreement, the Agents may sell Shares by any method permitted by law deemed to be an “at the market offering” under Rule 415(a)(4) under the Securities Act of 1933, as amended.

The issuance and sale, if any, of the Shares by the Company under the ATM Sales Agreement will be made pursuant to the Company’s effective registration statement on Form S-3 (Registration Statement No. 333-262226) (as amended, the “Registration Statement”), filed with the U.S. Securities and Exchange Commission (the “SEC”) on January 31, 2022, and declared effective on February 4, 2022. The Company agreed to pay the Agents a commission equal to 3.0% of the gross sales price from each sale of Shares and provide the Agents with customary indemnification and contribution rights. The ATM Sales Agreement may be terminated by the Agents or the Company at any time upon notice to the other party.

The Business Combination

TeraWulf completed its business combination with IKONICS Corporation (“IKONICS”) on December 13, 2021 (the “Closing Date”) pursuant to which, among other things, TeraCub Inc. (“TeraCub,” formerly known as TeraWulf Inc.) would effectively acquire IKONICS and become a publicly traded company on the Nasdaq, which was the primary purpose of the business combination. Under the terms of the Merger Agreement, each share of IKONICS common stock issued and outstanding immediately prior to the Closing Date was automatically converted into and exchanged for (i) one validly issued, fully paid and nonassessable share of Common Stock of TeraWulf, (ii) one contingent value right (“CVR”) pursuant to a Contingent Value Rights Agreement between TeraWulf and IKONICS (the “CVR Agreement”), and (iii) the right to receive $5.00 in cash, without interest. TeraCub common stock issued and outstanding immediately prior to the Closing Date was automatically converted into the right to receive a number of validly issued, fully paid and nonassessable shares of TeraWulf such that the TeraCub common stockholders prior to conversion would effectively control 98% of the total outstanding shares of TeraWulf immediately subsequent to the Closing Date.

Pursuant to the CVR Agreement, each shareholder of IKONICS as of immediately prior to the Closing Date, received one CVR for each outstanding share of common stock of IKONICS then held. The holders of the CVRs are entitled to receive 95% of the Net Proceeds (as defined in the CVR Agreement), if any, from the sale, transfer, disposition, spin-off, or license of all or any part of the pre-merger business of IKONICS completed within 18 months following the date of the merger, subject to a reserve of up to 10% of the Gross Proceeds (as defined in the CVR Agreement) from such transaction and such other amount to be retained to satisfy Retained Liabilities, as defined. The CVRs do not confer to their holders any voting or equity or ownership interest in IKONICS or TeraWulf and are not transferable, except in limited circumstances, and are not listed on any quotation system or traded on any securities exchange. The CVR Agreement will terminate after all payment obligations to the holders thereof have been satisfied. Holders of CVRs will not be eligible to receive payment for dispositions, if any, of any part of the pre-merger business of IKONICS after the eighteen-month anniversary of the Closing Date. As of September 30, 2023, the CVR liability included in the Company’s consolidated balance sheet is $1.4 million. During the year ended December 31, 2022, the Company completed sales of all IKONICS net assets held for sale for net proceeds of $13.2 million, of which $7.0 million remained in escrow under provisions of an

asset purchase agreement as of December 31, 2022. In February 2023, all escrowed funds were released to the Company. Subsequent to the asset sales, IKONICS’ name was changed to RM 101 Inc. (“RM 101”) and the entity has no remaining operations or employees.

Upon the consummation of the business combination, RM 101 common stock ceased trading on the Nasdaq and TeraWulf Common Stock began trading on the Nasdaq on December 14, 2021 under the ticker symbol “WULF.”

COVID-19

As of May 2023, the World Health Organization no longer considers COVID-19 a global health emergency, however the Company may from time to time experience disruptions to its business operations resulting from continued COVID-19-related supply interruptions, including miner delivery interruptions. The Company may also experience COVID-19-related delays in construction and obtaining necessary equipment in a timely fashion. To date, the Company has experienced minimal delays due to COVID-19 among its suppliers and contractors.

Restatement of Previously Issued Financial Statements

The Company identified an error in its historical unaudited interim consolidated statements of cash flows for each of the first three quarters of 2023. The misstatement relates solely to incorrectly classifying "payments of contingent value rights liability related to proceeds from sale of net assets held for sale" as an investing activity instead of as a financing activity in the respective unaudited interim consolidated statements of cash flows (the "Misclassification"). These payments were made in accordance with the Contingent Value Rights Agreements related to the Company's merger with RM 101 Inc. The Company determined that its unaudited interim consolidated financial statements for the quarterly periods ended March 31, 2023, June 30, 2023 and September 30, 2023 (the “Relevant Periods”) were materially misstated and should be restated. The Company believes that presenting all of this information regarding the Relevant Periods in this Form 10-Q/A allows investors to review all pertinent data in a single presentation. Therefore, the Company does not plan to amend its previously filed Quarterly Reports on Form 10-Q for June 30, 2023 and March 31, 2023. Accordingly, investors should no longer rely upon the Company's previously released financial statements for the Relevant Periods or any earnings releases or other communications relating to these Relevant Periods with respect to the Misclassification. The financial information that has been previously filed or otherwise reported for the Relevant Periods with respect to the Misclassification is superseded by the information in Note 17 to the Consolidated Financial Statements in this Form 10-Q/A. Because these amendments are treated as corrections of errors to our prior period financial statements, the amendments are considered to be a "restatement” under U.S. generally accepted accounting principles (“US GAAP”). Accordingly, the revised financial information included in this Form 10-Q/A has been identified as “As Restated.”

Results of Operations

The Company generates revenue in the form of bitcoin by providing hash computation services to a mining pool operator to mine bitcoin and validate transactions on the global Bitcoin Network using application-specific integrated circuit computers owned by the Company. The earned bitcoin are routinely sold for U.S. dollars. The Company also earns revenue by providing miner hosting services to third parties. 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. The Company's plan of operation for the next twelve months is to continue to increase the mining capacity at its operating mining facilities and to complete the construction of the third building at its Lake Mariner Facility.

Continuing Operations

All items included in loss from continuing operations in the consolidated statements of operations for the three and nine months ended September 30, 2023 and 2022 relate to its wholly-owned operations of its sole business segment, digital currency mining, due to the Company presenting the RM 101 business as discontinued operations for the three and nine months ended September 30, 2023 and 2022.

Revenue and Cost of Revenue

The following table presents revenue and cost of revenue (exclusive of depreciation) (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Revenue	$	18,955	$	3,864	$	45,944	$	5,466
Cost of revenue (exclusive of depreciation)	$	8,268	$	5,181	$	18,383	$	5,804

For the three months ended September 30, 2023 and 2022, revenue was $19.0 million and $3.9 million, respectively, an increase of $15.1 million. For the nine months ended September 30, 2023 and 2022, revenue was $45.9 million and $5.5 million, respectively, an increase of $40.4 million. In each case, the increase was due primarily to the increase in mining and hosting capacity due to infrastructure constructed and placed in service between September 30, 2022 and September 30, 2023, including Building 2 at the Lake Mariner Facility being energized and placed in service during the nine months ended September 30, 2023. Revenue from hosting increased $0.4 million and $4.0 million for the three and nine months ended September 30, 2023, respectively, as compared to the same periods in the prior year. During the nine months ended September 30, 2023, revenue from mining was $40.1 million and revenue from hosting was $5.8 million.

For the three months ended September 30, 2023 and 2022, cost of revenue (exclusive of depreciation) was $8.3 million and $5.2 million, respectively, an increase of approximately $3.1 million. For the nine months ended September 30, 2023 and 2022, cost of revenue (exclusive of depreciation) was $18.4 million and $5.8 million, respectively, an increase of approximately $12.6 million. In each case, the increase was primarily due to the increase in mining and hosting capacity due to infrastructure constructed and placed in service between September 30, 2022 and September 30, 2023. Cost of revenues is comprised primarily of power expense and, to a lesser degree, the cost of services provided under our miner hosting agreements. The Company records proceeds related to participation in demand response programs as a reduction in cost of revenue in the period corresponding to the underlying demand response program period; the amount of aggregate proceeds received or expected to be received were $1.7 million and $2.5 million for the three and nine months ended September 30, 2023, respectively, and $0.1 million in each of the same periods in the prior year. The Company is actively expanding its enrollment in such available programs in New York.

Costs and Expenses

The following table presents operating expenses (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Operating expenses	$	442	$	261	$	1,218	$	1,689
Operating expenses – related party	779		603		2,015		812
	$	1,221	$	864	$	3,233	$	2,501

For the three months ended September 30, 2023 and 2022, operating expenses (including related party expenses) was approximately $1.2 million and $0.9 million, respectively, an increase of $0.3 million. For the nine months ended September 30, 2023 and 2022, operating expenses (including related party expenses) was $3.2 million and $2.5 million, respectively, a net increase of $0.7 million. Operating expenses in the three months period increased due to higher insurance expense partially offset by lower equipment lease expense. During the nine month periods operating expenses decreased due to lower equipment lease expense partially offset by an increase in insurance expense. Operating expenses – related party increased due to increased staffing at the Lake Mariner Facility related to infrastructure constructed and placed in service between September 30, 2022 and 2023 and additionally, to a lesser degree, by an increase in ground lease expense.

The following table presents selling, general and administrative expenses (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Selling, general and administrative expenses	$	5,767	$	5,934	$	18,137	$	16,253
Selling, general and administrative expenses – related party	4,519		2,948		10,093		8,187
	$	10,286	$	8,882	$	28,230	$	24,440

For the three months ended September 30, 2023 and 2022, selling, general and administrative expenses (including related party expenses) were $10.3 million and $8.9 million, respectively, a net increase of $1.4 million. For the nine months ended September 30, 2023 and 2022, selling, general and administrative expenses (including related party expenses) were $28.2 million and $24.4 million, respectively, a net increase of $3.8 million. Selling, general and administrative expenses are comprised primarily of professional fees, legal fees, employee compensation and benefits, stock-based compensation to employees and consultants, insurance and general corporate expenses. The increases were primarily due to increased expense during the three and nine months ended September 30, 2023 as compared to the same periods in the prior year of related party expense to be settled with respect to common stock of $1.7 million and $2.5 million, respectively, stock-based compensation of $0.8 million and $2.7 million, respectively, and employee compensation and benefits of $0.3 million and $2.2 million, respectively. These increases were partially offset primarily due to decreased expense during the three and nine months ended September 30, 2023 as compared to the same periods in the prior year of legal fees of $0.5 million and $1.5 million, respectively, and insurance expense of approximately $0.5 million and $1.5 million, respectively. As previously disclosed, the Company has undertaken cost reduction initiatives targeted at reducing its overall selling, general and administrative expenses that are expected to benefit its operating profitability going forward.

Depreciation for the three months ended September 30, 2023 and 2022 was $8.2 million and $1.5 million, respectively, and for the nine months ended September 30, 2023 and 2022 was $20.1 million and $1.7 million, respectively. In each case, the increase was primarily due to the increase in mining capacity due to infrastructure constructed and placed in service between September 30, 2022 and September 30, 2023.

Impairment of digital currency for the three months ended September 30, 2023 and 2022 was $0.9 million and $0.1 million, respectively, and for the nine months ended September 30, 2023 and 2022 was $2.2 million and $0.7 million, respectively. Impairment of digital currency represents the decline in bitcoin prices during the Company’s holding period of its bitcoin. Bitcoin impairment is not reversed during its holding period but instead a gain, if any, is recognized upon its liquidation. Realized gain on sale of digital currency, representing such gains on bitcoin liquidation, for the three months ended September 30, 2023 and 2022 was $0.7 million and $0.1 million, respectively, and for the nine months ended September 30, 2023 and 2022 was $1.9 million and $0.1 million, respectively. In each case, the increase was due to increased bitcoins both earned and sold due to the increase in mining capacity between September 30, 2022 and September 30, 2023.

During the three and nine months ended September 30, 2022, the Company recorded a loss on nonmonetary miner exchange of $0.8 million related to an exchange agreement with Nautilus. No loss on nonmonetary miner exchange was recorded during the three and nine months ended September 30, 2023.

During the three and nine months ended September 30, 2023, the Company recorded a loss on disposal of property, plant and equipment of $0.4 million related to disposals of miners. No loss on disposal of property, plant, and equipment was recorded during the three and nine months ended September 30, 2022.

Interest expense for the three months ended September 30, 2023 and 2022 was $10.3 million and $7.2 million, respectively, an increase of $3.1 million. Interest expense for the nine months ended September 30, 2023 and 2022 was $25.5 million and $16.7 million, respectively, an increase of $8.8 million. Interest expense relates primarily to the Company’s term loan financing in the principal amount of $146.0 million as of September 30, 2023 as compared to $138.5 million as of September 30, 2022. The increase in interest expense for the three months ended September 30, 2023 as compared to the same period in the prior year is primarily due to an increase of approximately $3.8 million of amortization of debt issuance costs and debt discount related to the term loan financing partially offset by a decrease of $0.8 million in interest expense related to the stated interest rate, which remained unchanged, on the term loan financing. The increase in interest expense for the nine months ended September 30, 2023 as compared to the same period in the prior year is primarily due to an increase in the average principal amount outstanding which resulted in approximately $1.5 million of increase in interest expense related to the stated interest rate, which remained unchanged, on the term loan financing and to

47

an increase of approximately $8.8 million of amortization of debt issuance costs and debt discount related to the term loan financing. The Company’s term loan financing has a maturity date of December 1, 2024.

Income tax benefit was $0 for the three and nine months ended September 30, 2023 and $0.3 million for the three and nine months ended September 30, 2022. Based upon the level of historical U.S. losses and future projections over the period in which the net deferred tax assets are deductible, at this time, management believes it is more likely than not that the Company will not realize the benefits of the remaining deductible temporary differences, and as a result the Company has recorded a full valuation allowance against its gross deferred tax assets as of September 30, 2023 and 2022. During the three and nine months ended September 30, 2022, the Company sold the net assets held for sale of IKONICS, resulting in reversal of existing net deferred tax liabilities and a related tax benefit of $0.3 million recorded in income tax benefit in the consolidated statement of operations for the three and nine months ended September 30, 2022.

Equity in net loss of investee, net of tax

Equity in net loss of investee, net of tax for the three months ended September 30, 2023 and 2022 was $0.9 million and $12.7 million, respectively, and for the nine months ended September 30, 2023 and 2022 was $12.6 million and $14.6 million, respectively. For the three and nine months ended September 30, 2023, the amount includes an impairment loss of $0 and $13.6 million, respectively, on the distribution of miners from Nautilus to the Company whereby the miners were marked to fair value from book value on the date distributed. The impairment loss was the result of decreasing prices for miners between initial purchase and distribution. In each case, the remaining amounts represent TeraWulf’s proportional share of income or losses of Nautilus, which commenced principal operations in February 2023.

Loss from discontinued operations, net of tax

Loss from discontinued operations, net of tax for the three months ended September 30, 2023 and 2022 was $0.1 million and $0.9 million, respectively, and for the nine months ended September 30, 2023 was $0.1 million and $4.4 million, respectively. For the nine months ended September 30, 2022, the loss from discontinued operations, net of tax reported is comprised primarily of an impairment loss on discontinued operations of $5.8 million to write down the related carrying amounts of RM 101 to their fair values less estimated cost to sell, offset by a remeasurement gain of $1.4 million on the CVRs, which represents the contingent consideration purchase price component of the RM 101 acquisition. For the three and nine months ended September 30, 2023, all assets of RM 101 had been sold prior to the start of the respective periods and RM 101 had no operations or employees.

Non-GAAP Measure

The Company presents adjusted EBITDA, which is not a measurement of financial performance under generally accepted accounting principles in the United States (“GAAP”). The Company’s non-GAAP “Adjusted EBITDA” excludes (i) impacts of interest, taxes, depreciation and amortization; (ii) preferred stock dividends, stock-based compensation expense and related party expense to be settled with respect to common stock, all of which are non-cash items that the Company believes are not reflective of its general business performance, and for which the accounting requires management judgment, and the resulting expenses could vary significantly in comparison to other companies; (iii) equity in net loss of investee, net of tax, related to Nautilus; (iv) costs related to non-routine regulatory activities, which costs management does not believe are reflective of the Company’s ongoing operating activities; (v) other income which is related to interest income or income for which management believes is not reflective of the Company’s ongoing operating activities; and (vi) gains and losses related to discontinued operations that are not be applicable to the Company’s future business activities. The Company’s non-GAAP Adjusted EBITDA also includes the impact of distributions from investee received in bitcoin related to a return on the Nautilus investment, which management believes, in conjunction with excluding the impact of equity in net loss of investee, net of tax, is reflective of assets available for the Company’s use in its ongoing operations as a result of its investment in Nautilus.

Management believes that providing this non-GAAP financial measure that excludes these items allows for meaningful comparisons between the Company's core business operating results and those of other companies, and provides the Company with an important tool for financial and operational decision making and for evaluating its own core business operating results over different periods of time. In addition to management's internal use of non-GAAP adjusted EBITDA, management believes that adjusted EBITDA is also useful to investors and analysts in comparing the Company’s performance across reporting periods on a consistent basis. Management believes the foregoing to be the case even though some of the excluded items involve cash outlays and some of them recur on a regular basis (although management does not believe any of such items are normal operating expenses necessary to generate the Company’s bitcoin related revenues). For example, the Company expects that share-based compensation expense, which is excluded from adjusted EBITDA, will continue to be a significant recurring expense over the coming years and is an important part of the compensation

48

provided to certain employees, officers, directors and consultants. Additionally, management does not consider any of the excluded items to be expenses necessary to generate the Company’s bitcoin related revenue.

The Company's adjusted EBITDA measure may not be directly comparable to similar measures provided by other companies in the Company’s industry, as other companies in the Company’s industry may calculate non-GAAP financial results differently. The Company's adjusted EBITDA is not a measurement of financial performance under GAAP and should not be considered as an alternative to operating (loss) income or any other measure of performance derived in accordance with GAAP. Although management utilizes internally and presents adjusted EBITDA, the Company only utilizes that measure supplementally and does not consider it to be a substitute for, or superior to, the information provided by GAAP financial results. Accordingly, adjusted EBITDA is not meant to be considered in isolation of, and should be read in conjunction with, the information contained in the Company’s consolidated financial statements, which have been prepared in accordance with GAAP.

The following table is a reconciliation of the Company’s non-GAAP adjusted EBITDA to its most directly comparable GAAP measure (i.e., net loss attributable to common stockholders) for the periods indicated (in thousands):

The Company incurred a net loss attributable to common stockholders of $63.7 million for the nine months ended September 30, 2023. The Company began mining bitcoin in March 2022 and has 5.5 EH/s of operating capacity across the Lake Mariner Facility and the Nautilus Cryptomine Facility as of September 30, 2023, which the Company expects will result in positive cash flows from operations subsequently. Until achieving this operational milestone, the Company has relied primarily on proceeds from its issuances of debt and equity and sale of bitcoin mined to fund its principal operations. The principal uses of cash are for the operation and buildout of mining facilities, debt service

Contractual Obligations and Other Commitments

The Company has one outstanding miner purchase agreement, with Bitmain Technologies Delaware Limited (“Bitmain Delaware”) (the “July 2023 Bitmain Agreement”). The July 2023 Bitmain Agreement provides that the Company will receive 15,138 S19j XP miners from Bitmain Delaware, with an option to receive an additional 3,362 miners, pursuant to certain payment timing conditions, for delivery in the fourth quarter of 2023 for a total purchase price of $75.4 million. The Company is entitled to apply coupons equivalent to 30% of the total purchase price, resulting in an estimated effective purchase price of $53.4 million for 18,500 miners. As of September 30, 2023, the Company had made payments of $14.3 million, including purchase of coupons, representing 27% of the effective purchase price.

In September 2023, the Company entered into a binding letter of intent with Bitmain Development PTE. Ltd. (“Bitmain PTE”), for the purchase of at least 1,200 PH of Antminer S21 miners, pursuant to which the Company paid a security deposit of $1.2 million during the nine months ended September 30, 2023. The purchase price per Antminer S21 remains subject to confirmation by Bitmain PTE. If, following receipt of Bitmain PTE's notice of the Antminer S21 purchase price, the Company elects not to purchase the applicable quantity of Antminer S21 miners, the $1.2 million security deposit will be credited to the Company's account with Bitmain PTE. If the Company elects to purchase the applicable quantity of Antminer S21 miners at a time when they are out of stock, the Company is entitled to a refund of its $1.2 million security deposit.

The Company is counterparty to the Amended and Restated Talen Joint Venture Agreement dated August 27, 2022 (“A/R Joint Venture Agreement”). Under this A/R Joint Venture Agreement, the Company has invested $135.4 million on a net basis and has right-sized its equity ownership interest to 25% of the joint venture. The Company does not expect any additional material capital contributions to be required.

Financial Condition

There is limited historical financial information about the Company upon which to base an evaluation of its performance. The Company has 5.5 EH/s of operating capacity across the Lake Mariner Facility and the Nautilus Cryptomine Facility as of September 30, 2023, which the Company expects to result in positive cash flows from operations subsequently. To date, the Company relied primarily on proceeds from its issuances of debt and equity and sale of bitcoin mined to fund its principal operations. TeraWulf expects to fund its business operations and incremental infrastructure buildout primarily through positive cash flows from operations, including sales of mined bitcoin or through the provision of miner hosting services, cash on the balance sheet and the issuance of equity securities.

During the nine months ended September 30, 2023, the Company accomplished several notable steps to achieve expected positive cash flows from operations, namely: (1) the Company amended its long-term debt agreement (see Note 9) to, among other changes, remove the fixed principal amortization through April 7, 2024 and, potentially, through maturity, (2) the Company received net proceeds of $57.7 million through the issuance of shares of our common stock, par value $0.001 per share (the “Common Stock”), Common Stock warrants and convertible promissory notes, which along with cash flows from operations, is expected to be sufficient to fund the Company’s operating expenses in the months prior to achieving a free cash flow positive enterprise (3) commenced mining activities at the Nautilus Cryptomine Facility and the Company deems that it has funded all known and expected capital commitments at that facility, (4) the Company received substantially all contracted miners from the miner suppliers and has no remaining outstanding financial commitments under the miner purchase agreements for the existing operations at the Lake Mariner Facility and the Nautilus Cryptomine Facility, (5) the Company has received the quantity of miners sufficient to fully utilize mining capacity in service at the Lake Mariner Facility for buildings one and two and the Nautilus Cryptomine Facility and (6) the construction activities at the Lake Mariner Facility and the Nautilus Cryptomine Facility are substantially complete as of September 30, 2023, although the Company intends to expand its infrastructure at the Lake Mariner Facility. Additionally, if a business need requires its use, the Company has an active ATM Sales Program, which had a remaining capacity of $162.2 million as of September 30, 2023. The issuance of Common Stock under this agreement would be made pursuant to the Company’s effective registration statement on Form S-3 (Registration statement No. 333-262226). The Company has determined that it is probable that these actions and conditions will allow the Company to generate positive cash flows from operations and be able to realize its assets and discharge its liabilities and commitments in the normal course of business and, therefore, there is not substantial doubt about the Company’s ability to continue as a going concern through at least the next twelve months. The consolidated financial statements do not include any adjustments that might result from TeraWulf’s possible inability to continue as a going concern.

Critical Accounting Policies and Estimates

The above discussion and analysis of the Company’s financial condition and results of operations are based upon its consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of the Company’s consolidated financial statements requires the application of accounting policies and the use of estimates. The accounting policies most important to the preparation of the consolidated financial statements and estimates that require management’s most difficult, subjective or complex judgments are described below.

See Note 2 of the Notes to Consolidated Financial Statements included in Item 1 of this Quarterly Report on Form 10-Q/A and Note 2 of the Notes to Consolidated Financial Statements included in Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 for a summary of the Company’s significant accounting policies.

Variable Interest Entities

Variable interest entities (“VIE”) are legal entities in which equity investors do not have (i) sufficient equity at risk for the legal entity to finance its activities without additional subordinated financial support, or (ii) as a group, the power, through voting or similar rights, to direct the activities of the legal entity that most significantly impact the entity’s economic performance, or (iii) the obligation to absorb the expected losses of the legal entity or the right to receive expected residual returns of the legal entity. The Company would consolidate any VIE in which it has a controlling financial interest through being deemed to be the primary beneficiary of the VIE. The primary beneficiary of a VIE has both of the following characteristics: (1) the power to direct the activities of the VIE that most significantly impact its economic performance; and (2) the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could be significant to the VIE. If both characteristics are met, the Company considers itself to be the primary beneficiary and therefore will consolidate that VIE into its consolidated financial statements.

The Company determines whether it is the primary beneficiary of a VIE upon initial involvement with a VIE and reassesses whether it is the primary beneficiary of a VIE on an ongoing basis. The determination of whether an entity is a VIE and whether the Company is the primary beneficiary of a VIE is based upon facts and circumstances for the VIE and requires significant judgments such as whether the entity is a VIE, whether the Company’s interest in a VIE is a variable interest, the determination of the activities that most significantly impact the economic performance of the entity, whether the Company controls those activities, and whether the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.

In 2021, the Company entered into a joint venture, Nautilus, with an unrelated co-venturer to develop, construct and operate a bitcoin mining facility in Pennsylvania. Due to the initial nature of the joint venture and the continued commitment for additional financing, the Company determined Nautilus is a VIE. While the Company has the ability to exercise significant influence over Nautilus, the Company has determined that it does not have the power to direct the activities that most significantly impact the economic performance of Nautilus. Initially, the power to direct the activities of Nautilus that most significantly impact Nautilus’ economic performance were shared equally by both parties within the joint venture due to the requirement for both equity holders to approve many of the key operating decisions and when not equally shared, were predominantly under the control of the co-venturer, including through the co-venturer’s majority representation on the board of managers. As such, the Company has determined that it is not the primary beneficiary of Nautilus and, therefore, has accounted for this entity under the equity method of accounting. Risks associated with the Company’s involvement with Nautilus include a commitment to potentially fund additional equity investments. During the nine months ended September 30, 2023, the Company reduced its ownership interest in Nautilus to 25%.

Mining Pool

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

52

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.

There is no significant financing component in these transactions.

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.

Consideration payable to the customer in the form of a pool operator fee, which is incurred only to the extent that the Company has generated FPPS consideration, is deducted from the bitcoin the Company receives and is recorded as contra-revenue, as it does not represent a payment for a distinct good or service.

Data Center Hosting

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

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.

53

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.

Issuance of Debt with Common Stock or Warrants; Debt Modification

On December 1, 2021, the Company entered into a Loan, Guaranty and Security Agreement with Wilmington Trust, National Association as administrative agent (the “LGSA”), which consists of a $123.5 million term loan facility. In connection with the LGSA, the Company issued to the holders of the Term Loan 839,398 shares of Common Stock, which is a quantity of Common Stock representing 1.5% of the outstanding shares of the publicly registered shares of TeraWulf subsequent to the closing of the LGSA. The allocation of proceeds between the debt instrument and any other components included in the debt issuance, including Common Stock, is generally based on the relative fair value allocation method. In applying the relative fair value allocation method, the determination of the fair value of the Common Stock issued and the fair value of the Term Loan independent of the Common Stock issued requires significant judgment. As a measure of sensitivity, a 10% change in the estimated fair value of the Term Loan component would result in a $1.9 million change in the fair value allocated to each of the Term Loan and equity components.

In July 2022, the Company entered into an amendment to the LGSA (the “First Amendment”), which included an additional borrowing of $15.0 million and the issuance of warrants to purchase 5,787,732 shares of Common Stock at $0.01 per share. The accounting for debt modifications is complex and requires significant judgment. Potential accounting outcomes include troubled debt restructuring accounting, extinguishment accounting or modification accounting, each with different implications for the consolidated financial statements. The Company has determined that modification accounting is applicable. Additionally, debt modification accounting requires the determination of the fair value of the warrants issued, which requires significant judgment. As a measure of sensitivity, a 10% change in the estimated fair value of the warrants would result in a $0.3 million change in the recorded value of the borrowing under the First Amendment.

In October 2022, the Company entered into a third amendment (the “Third Amendment”) to the LGSA, which included an additional borrowing of $7.5 million and the issuance of warrants to purchase 2,667,678 shares of Common Stock at $0.01 per share. The accounting for debt modifications is complex and requires significant judgment. Potential accounting outcomes include troubled debt restructuring accounting, extinguishment accounting or modification accounting, each with different implications for the consolidated financial statements. The Company has determined that modification accounting is applicable. Additionally, debt modification accounting requires the determination of the fair value of the warrants issued, which requires significant judgment. As a measure of sensitivity, a 10% change in the estimated fair value of the warrants would result in a $0.2 million change in the recorded value of the borrowing under the Third Amendment.

In March 2023, the Company entered into a fifth amendment to the LGSA, which included the issuance of warrants to purchase 27,759,265 shares of Common Stock at $0.01 per share and 13,879,630 shares of Common Stock at $1.00 per share. The accounting for debt modifications is complex and requires significant judgment. Potential accounting outcomes include troubled debt restructuring accounting, extinguishment accounting or modification accounting, each with different implications for the consolidated financial statements. The Company has determined that modification accounting is applicable. Additionally, debt modification accounting requires the determination of the fair value of the warrants issued,

54

which requires significant judgment. As a measure of sensitivity, a 10% change in the estimated fair value of the warrants would result in a $1.6 million change in the recorded value of the borrowing under the Third Amendment.

Convertible Instruments

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.

Income Taxes

The Company accounts for income taxes pursuant to the provision of ASC 740-10, “Accounting for Income Taxes” which requires, among other things, an asset and liability approach to calculating deferred income taxes. The asset and liability approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. A valuation allowance is provided to offset any net deferred tax assets for which management believes it is more likely than not that the net deferred tax asset will not be realized. The Company follows the provision of the ASC 740-10 related to Accounting for Uncertain Income Tax Positions. When tax returns are filed, it is more likely than not that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. In accordance with the guidance of ASC 740-10, the benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely that not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. The tax benefits recognized in the consolidated financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with the tax positions taken that exceeds the amount measured as described above should be reflected as a liability for uncertain tax benefits in the Company’s balance sheets along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The most critical estimate for income taxes is the determination of whether to record a valuation allowance for any net deferred tax asset, including net loss carryforwards, whereby management must estimate whether it is more likely than not that the deferred tax asset would be realized.

ITEM 3.    Quantitative and Qualitative Disclosures About Market Risk

As a smaller reporting company, we are not required to provide this information.

ITEM 4.    Controls and Procedures

Disclosure Controls and Procedures

Our management evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q/A. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of such period, are effective to provide reasonable assurance that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act are:

•Recorded, processed, summarized, and reported within the time periods specified in the SEC rules and forms, and

•Accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Restatement of Previously Issued Financial Statements

The Company identified an error in its historical unaudited interim consolidated statements of cash flows for each of the first three quarters of 2023. 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. The Company determined that its unaudited interim consolidated financial statements for the quarterly periods ended March 31, 2023, June 30, 2023 and September 30, 2023 were materially misstated and should be restated. The restatements are set forth in detail in Note 17 to the Consolidated Financial Statements. We identified a material weakness in internal control over financial reporting related to the inadequate design or operation of management's review controls over classification in the consolidated statements of cash flows of payments made related to business combinations.

A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. As a result of the material weakness, TeraWulf’s management concluded that its internal control over financial reporting and related disclosure controls and procedures were not effective based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission.

Material Weakness in Internal Control Over Financial Reporting

The Company's management has actively engaged in implementing remediation plans to address the control deficiency outlined above. The remediation efforts include adding procedures to our review controls over classification in the consolidated statements of cash flows of payments made related to business combinations to ensure that our consolidated financial statements are prepared in accordance with U.S. GAAP. The material weakness will not be considered remediated until management designs and implements effective controls that operate for a sufficient period of time and management has concluded, through testing, that these controls are effective. If TeraWulf’s remedial measures are insufficient to address the material weakness, or if additional material weaknesses or significant deficiencies in its internal control are discovered or occur in the future, its financial statements may contain material misstatements and TeraWulf could be required to restate its financial results.

Other than the remediation efforts in process, as described above, there were no changes in the Company’s internal control over financial reporting that occurred during the three months ended September 30, 2023 that have materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects.

56

PART II. OTHER INFORMATION

ITEM 1.    Legal Proceedings

From time to time, TeraWulf may be involved in various legal and administrative proceedings, lawsuits and claims incidental to the conduct of its business. Some of these proceedings, lawsuits or claims may be material and involve highly complex issues that are subject to substantial uncertainties and could result in damages, fines, penalties, non-monetary sanctions or relief. TeraWulf recognizes provisions for claims or pending litigation when it determines that an unfavorable outcome is probable, and the amount of loss can be reasonably estimated. Due to the inherent uncertain nature of litigation, the ultimate outcome or actual cost of settlement may materially vary from estimates. TeraWulf was not subject to any material pending legal and administrative proceedings, lawsuits or claims during the period covered by this Quarterly Report. TeraWulf’s business and operations are also subject to extensive regulation, which may result in regulatory proceedings against TeraWulf.

ITEM 1A.    Risk Factors

Our business faces many risks. Before deciding whether to invest in our Common Stock, in addition to the other information set forth in this quarterly report on Form 10-Q/A, you should carefully consider the risk factors discussed in our Annual Report on Form 10-K, which is incorporated herein by reference. If any of the risks or uncertainties described therein actually occurs, our business, financial condition, results of operations or cash flow could be materially and adversely affected. This could cause the trading price of our Common Stock to decline, resulting in a loss of all or part of your investment. The risks and uncertainties we have described are not the only ones facing our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations. There have been no material changes to the risk factors set forth in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q.

TeraWulf may be at a higher risk of litigation and other legal proceedings due to heightened regulatory scrutiny of the cryptocurrency industry, which could ultimately be resolved against TeraWulf, requiring material future cash payments or charges, which could impair TeraWulf’s financial condition and results of operations.

The size, nature and complexity of the Company’s business could make it susceptible to various claims, both in litigation and binding arbitration proceedings, legal proceedings, and government investigations, due to the heightened regulatory scrutiny following the recent disruptions in the crypto asset markets, including the FTX bankruptcy. This and similar events have caused price volatility and undermined confidence in the cryptocurrency industry. Although we had no direct exposure to FTX, the failure or insolvency of large exchanges like FTX or other significant players in the cryptocurrency could adversely affect an investment in us or negatively impact our results of operations.

The Company believes that since cryptocurrency mining, and the digital asset industry generally, is a relatively new business sector, it is more likely subject to government investigation and regulatory determination, particularly following the recent cryptocurrency market participant bankruptcies described elsewhere herein. Any claims, regulatory proceedings or litigation that could arise in the course of the Company’s business could have a material adverse effect on the Company, its business or operations, or the industry as a whole.

We have identified material weaknesses in our internal control over financial reporting which may, if not effectively remediated, result in additional material misstatements in our financial statements.

TeraWulf’s management is responsible for establishing and maintaining adequate internal control over our financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934. As disclosed in Item 9A, “Controls and Procedures” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and Part I, Item 4, "Controls and Procedures" of this Form 10-Q/A, management identified material weaknesses in our internal control over financial reporting. The related control deficiencies resulted in material misstatements in our previously issued interim financial statements for interim periods within the fiscal year ending December 31, 2022 (the "Relevant 2022 Periods") and the quarterly periods ended March 31, 2023, June 30, 2023, and September 30, 2023 (the "Relevant 2023 Periods"). The misstatements for the Relevant 2022 Periods relate 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 unaudited consolidated statements of cash flows. The misstatement for the Relevant 2023 Periods relate 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.

57

A material weakness is defined as a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. As a result of the material weakness, TeraWulf’s management concluded that its internal control over financial reporting and related disclosure controls and procedures were not effective based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission.

TeraWulf’s management is actively engaged in developing a remediation plan designed to address these material weaknesses. If TeraWulf’s remedial measures are insufficient to address the material weaknesses, or if additional material weaknesses or significant deficiencies in its internal control are discovered or occur in the future, its financial statements may contain material misstatements and TeraWulf could be required to restate its financial results.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

ORGANIZATION

ORGANIZATION

Organization

TeraWulf Inc. (“TeraWulf” or the “Company”) is a digital asset technology company with a core business of digital infrastructure and energy development to enable sustainable bitcoin mining. TeraWulf’s principal business consists of developing and operating bitcoin mining facilities in the United States that are fueled by clean, low cost and reliable power sources. The Company generates revenue in the form of bitcoin by providing hash computation services to a mining pool operator to mine bitcoin and validate transactions on the global bitcoin network using application-specific integrated circuit computers (“ASIC” or “miners”) owned by the Company. The earned bitcoin are routinely sold for U.S. dollars. The Company also earns revenue by providing miner hosting services to third parties. 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.

TeraWulf currently owns and operates, either independently or through a joint venture, two bitcoin mining facilities: the Lake Mariner Facility located in upstate New York; and the Nautilus Cryptomine Facility located in central Pennsylvania. The Company’s wholly-owned Lake Mariner Facility began mining bitcoin in March 2022 and, as of September 30, 2023, the Company has energized two buildings and additional infrastructure comprising 110 MW of capacity. The Nautilus Cryptomine Facility, which has been developed and constructed through a joint venture (see Note 11), commenced mining operations in February 2023 and, in April 2023, achieved full energization of the Company’s allotted infrastructure capacity of 50 MW.

On December 13, 2021, TeraWulf Inc. completed a strategic business combination (the “Merger”) with IKONICS Corporation ("IKONICS") , a Minnesota corporation, pursuant to which, among other things, the Company effectively acquired IKONICS and became a publicly traded company on the National Association of Securities Dealers Automated Quotations (“Nasdaq”), which was the primary purpose of the business combination. IKONICS’ traditional business was the development and manufacturing of high-quality photochemical imaging systems for sale primarily to a wide range of printers and decorators of surfaces. Customers’ applications were primarily screen printing and abrasive etching. TeraWulf initially classified the IKONICS business as held for sale and discontinued operations in its consolidated financial statements. During the year ended December 31, 2022, the Company completed sales of substantially all of IKONICS’ historical net assets (see Note 3). Subsequent to the asset sales, IKONICS’ name was changed to RM 101 Inc. (“RM 101”).

Risks and Uncertainties

Liquidity and Financial Condition

The Company incurred a net loss attributable to common stockholders of $63.7 million and negative cash flows from continuing operations of $6.9 million for the nine months ended September 30, 2023. As of September 30, 2023, the Company had balances of cash and cash equivalents and restricted cash of $6.6 million, a working capital deficiency of $95.5 million, total stockholders’ equity of $153.9 million and an accumulated deficit of $249.4 million. The Company has 5.5 EH/s of operating capacity across the Lake Mariner Facility and the Nautilus Cryptomine Facility as of September 2023, which the Company expects to result in positive cash flows from operations subsequently. To date, the Company has relied primarily on proceeds from its issuances of debt and equity and sale of bitcoin mined to fund its principal operations.

In accordance with development of its bitcoin mining facilities, during the nine months ended September 30, 2023, the Company invested approximately $41.4 million for purchases of and deposits on plant and equipment. Also, during the nine months ended September 30, 2023, the Company invested $2.8 million in its joint venture (see Note 11). TeraWulf expects to fund its business operations and incremental infrastructure buildout primarily through positive cash flows from operations, including sales of mined bitcoin or through miner hosting services, cash on the balance sheet and the issuance of equity securities.

During the nine months ended September 30, 2023, the Company accomplished several notable steps to achieve expected positive cash flows from operations, namely: (1) the Company amended its long-term debt agreement (see Note 9) to, among other changes, remove the fixed principal amortization through April 7, 2024 and, potentially, through maturity, (2) the Company received net proceeds of $57.7 million through the issuance of shares of our common stock, par value $0.001 per share (the “Common Stock”), Common Stock warrants and convertible promissory notes (see Notes 13 and 14), which along with cash flows from operations, is expected to be sufficient to fund the Company’s operating expenses in the months prior to achieving a free cash flow positive enterprise (3) commenced mining activities at the Nautilus Cryptomine Facility and the Company deems that it has funded all known and expected capital commitments at that facility, (4) the

Company received substantially all contracted miners from the miner suppliers and has no remaining outstanding financial commitments under the miner purchase agreements (see Notes 11 and 12) for the existing operations at the Lake Mariner Facility and the Nautilus Cryptomine Facility, (5) the Company has received the quantity of miners sufficient to fully utilize mining capacity in service at the Lake Mariner Facility for buildings one and two and the Nautilus Cryptomine Facility and (6) the construction activities at the Lake Mariner Facility for buildings one and two and the Nautilus Cryptomine Facility are substantially complete as of September 30, 2023, although the Company intends to expand its infrastructure at the Lake Mariner Facility. Additionally, if a business need requires its use, the Company has an active at-the-market sales agreement for sale of shares of Common Stock having an aggregate offering price of up to $200.0 million (the “ATM Sales Agreement”), which had a remaining capacity of $162.2 million as of September 30, 2023. The issuance of Common Stock under this agreement would be made pursuant to the Company’s effective registration statement on Form S-3 (Registration statement No. 333-262226). The Company has determined that it is probable that these actions and conditions will allow the Company to generate positive cash flows from operations and be able to realize its assets and discharge its liabilities and commitments in the normal course of business and, therefore, there is not substantial doubt about the Company’s ability to continue as a going concern through at least the next twelve months. The consolidated financial statements do not include any adjustments that might result from TeraWulf’s possible inability to continue as a going concern.

COVID-19

As of May 2023, the World Health Organization no longer considers COVID-19 a global health emergency, however the Company may from time to time experience disruptions to its business operations resulting from continued COVID-19-related supply interruptions, including miner delivery interruptions. The Company may also experience COVID-19-related delays in construction and obtaining necessary equipment in a timely fashion. To date, the Company has experienced minimal delays due to COVID-19 among its suppliers and contractors.

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

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.

Prior Interim Period Restatement

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.

Use of Estimates in the Financial Statements

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.

Cash and Cash Equivalents

Highly liquid instruments with an original maturity of three months or less are classified as cash equivalents. As of September 30, 2023 and December 31, 2022, the Company had cash and cash equivalents of $6.6 million and $8.3 million, including restricted cash, respectively.

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.

Restricted Cash

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).

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets that total to the amounts shown in the consolidated statements of cash flows (in thousands):

	September 30, 2023		December 31, 2022
Cash and cash equivalents	$	6,595	$	1,279
Restricted cash	—		7,044
Cash and cash equivalents and restricted cash	$	6,595	$	8,323

Segment Reporting

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

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.

Impairment of Long-lived Assets

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.

Leases

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.

As of September 30, 2023 and December 31, 2022, the Company was not a counterparty to any finance leases.

Debt Modification

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

consolidated statements of operations. Amounts paid by the Company to the lenders, including upfront fees and the fair value of warrants issued, are included in future cash flows for accounting treatment determination and, if debt modification is applicable, are also included in the determination of yield adjustment.

Convertible Instruments

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.

Warrants

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.

Nonmonetary Transactions

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.

Stock Issuance Costs

Stock issuance costs are recorded as a reduction to issuance proceeds. Stock issuance costs incurred prior to the closing of the related issuances, including under shelf registration statements, are recorded in other assets in the consolidated balance sheets if the closing of the related issuance is deemed probable.

Held for Sale and Discontinued Operations Classification

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.

Revenue Recognition

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:

•Step 1: Identify the contract with the customer

•Step 2: Identify the performance obligations in the contract

•Step 3: Determine the transaction price

•Step 4: Allocate the transaction price to the performance obligations in the contract

•Step 5: Recognize revenue when the Company satisfies a performance obligation

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).

If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.

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

•Constraining estimates of variable consideration

•The existence of a significant financing component in the contract

•Noncash consideration

•Consideration payable to a customer

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.

Mining Pool

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.

There is no significant financing component in these transactions.

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.

Consideration payable to the customer in the form of a pool operator fee, which is incurred only to the extent that the Company has generated FPPS consideration, is deducted from the bitcoin the Company receives and is recorded as contra-revenue, as it does not represent a payment for a distinct good or service.

Data Center Hosting

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

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.

Cost of Revenue

Cost of revenue for mining pool revenue is comprised primarily of direct costs of electricity but excludes depreciation which is separately presented. Cost of revenue for data center hosting is comprised primarily of direct costs of electricity, labor and internet provision.

Stock-based Compensation

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.

Power Curtailment Credits

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.

Other Income

Other income consists primarily of interest income on bank deposits. The Company recorded other income of $0 and $39,000 during the three and nine months ended September 30, 2023, respectively, related to a disgorgement of short-swing profits arising from trades by a non-management insider under Section 16(b) of the Securities and Exchange Act of 1934.

Loss per Share

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.

Concentrations

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.

Business Combination and Asset Acquisition [Abstract]

BUSINESS COMBINATION, ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONS

BUSINESS COMBINATION, ASSETS HELD FOR SALE AND DISCONTINUED OPERATIONSOn December 13, 2021, the Company completed the Merger with RM 101 (formerly known as IKONICS Corporation) pursuant to which, among other things, the Company effectively acquired RM 101 and became a publicly traded company on the Nasdaq. The consideration in the Merger included, among other things, contractual contingent value rights (“CVR”) per a Contingent Value Rights Agreement (the “CVR Agreement”). Pursuant to the CVR Agreement, each shareholder of RM 101 as of immediately prior to the Merger, received one non-transferable CVR for each outstanding share of common stock of RM 101 then held. The holders of the CVRs are entitled to receive 95% of the Net Proceeds (as defined in the CVR Agreement), if any, from the sale, transfer, disposition, spin-off, or license of all or any part of the pre-merger business of RM 101. Payments under the CVR Agreement are calculated quarterly, are paid on the sixtieth day after the respective quarterly calculation period and are subject to a reserve of up to 10% of the Gross Proceeds (as defined in the CVR Agreement) from such transaction or more under certain conditions. The Company made a CVR payment in the amount of $3.9 million in February 2023 related to the quarterly calculation for the fourth quarter of 2022. The Company made a CVR payment in the amount of $5.7 million in May 2023 related to the quarterly calculation for the first quarter of 2023. The CVRs do not confer to the holders thereof any voting or equity or ownership interest in TeraWulf. The CVRs are not transferable, except in limited circumstances, and are not listed on any quotation system or traded on any securities exchange. The CVR Agreement will terminate after all payment obligations to the holders thereof have been satisfied.

Holders of CVRs (the “CVR Holders”) will not be eligible to receive payment for dispositions, if any, of any part of the pre-merger business of RM 101 after the eighteen-month anniversary of the closing of the Merger.

In August 2022, RM 101 sold a certain property, including a warehouse, to a third party for $6.7 million gross with net sale proceeds of $6.2 million. The Definitive Agreement governing the sale included certain indemnifications which were subject to an $850,000 limitation and which expired in August 2023.

In August 2022, RM 101 sold (i) certain property, including a warehouse and a building which houses manufacturing, operations and administration, (ii) substantially all of its working capital and (iii) its historical business to a third party for $7.7 million gross, including net working capital, with net sale proceeds of $7.0 million. The Asset Purchase Agreement (the “APA”) governing the sale was structured as an asset sale. The APA included certain indemnifications which were subject to a $650,000 limitation and a related escrow of that amount upon consummation of the transaction. Substantially all the remaining purchase price was placed into escrow upon consummation of the transaction pending the completion of certain remaining environmental testing and remediation resulting therefrom, if any. At December 31, 2022, proceeds from this sale were included in restricted cash in the consolidated balance sheet. In February 2023, all escrowed funds were released to the Company.

In accordance with the CVR Agreement, as of September 30, 2023, the Company has made aggregate distributions of $9.6 million of proceeds to the CVR Holders. As of September 30, 2023, all RM 101 assets previously held for sale had been sold and the estimated remaining CVR liability of $1.4 million is included in contingent value rights in the consolidated balance sheet. The final CVR payment will be made on or about November 28, 2023.

Upon acquisition, the RM 101 business met the assets held-for-sale and discontinued operations criteria and is reflected as discontinued operations held for sale in these consolidated financial statements. The Company determined that the RM 101 business qualified as assets held for sale as management committed to a plan to sell the business, the business was in readily sellable form and it was deemed probable that the business would be sold in a twelve-month period. All net assets held for sale had been sold as of December 31, 2022. The loss from discontinued operations, net of tax presented in the consolidated statements of operations includes the following results of RM 101 (in thousands):

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-level fair value hierarchy prioritizing the inputs to valuation techniques is used to measure fair value. The levels are as follows: (Level 1) observable inputs such as quoted prices in active markets for identical assets or liabilities; (Level 2) observable inputs for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs other than quoted prices that are observable either directly or indirectly from market data; and (Level 3) unobservable inputs in which there is little or no market data, which require the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.

The following table illustrates the financial instruments measured at fair value on a non-recurring basis segregated by hierarchy fair value levels as of September 30, 2023 (in thousands):

	Carrying Value		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Other Unobservable Inputs (Level 3)		Remeasurement Gain (Loss)
Contingent consideration liability - Contingent Value Rights	$	1,366	$	—	$	1,366	$	—	$	(64)
	$	1,366	$	—	$	1,366	$	—	$	(64)

The following table illustrates the financial instruments measured at fair value on a non-recurring basis segregated by hierarchy fair value levels as of December 31, 2022 (in thousands):

	Carrying Value		Quoted Prices in Active Markets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Other Unobservable Inputs (Level 3)		Remeasurement Gain (Loss)
Contingent consideration liability - Contingent Value Rights (1)	$	10,900	$	—	$	10,900	$	—	$	1,100
	$	10,900	$	—	$	10,900	$	—	$	1,100

(1)During the three months ended March 31, 2022, the Company changed the valuation approach from the use of other unobservable inputs to other observable inputs based on information obtained through the active marketing and sale of the underlying assets.

The Company has determined the long-term debt fair value as of September 30, 2023 is approximately $135.1 million (see Note 9). The carrying values of cash and cash equivalents, restricted cash, prepaid expenses, amounts due from related parties, other current assets, accounts payable, accrued construction liabilities, other accrued liabilities and other amounts due to related parties are considered to be representative of their respective fair values principally due to their short-term maturities. There were no additional material non-recurring fair value measurements as of September 30, 2023 and December 31, 2022, except for (i) the calculation of fair value of Common Stock warrants issued in connection with amendments to the Company’s long-term debt agreement (see Note 9), in connection with the issuance of Common Stock (see Note 15), in connection with a Common Stock exchange agreement (see Note 14) and on a standalone basis (see Note 14), (ii) the change in fair value of embedded derivatives in certain of the Company’s convertible promissory notes (see Note 14) and (iii) the calculation of fair value of nonmonetary assets distributed from the Company’s joint venture (see Note 11).

The Company utilized a Black-Scholes option pricing model and the application of a discount for lack of marketability (“DLOM”) to value its Common Stock warrants issued in connection with the New Term Facility and to value its Common Stock warrants issued in connection with the Fifth Amendment (each as defined in Note 9). The DLOM is applied primarily due to contractual restrictions on the exercise of the respective warrants. The estimated fair value of the warrants

is determined using Level 3 inputs. Inherent in the model and fair value estimate are assumptions related to expected share-price volatility, expected life, risk-free interest rate, dividend yield and DLOM. The Company estimates volatility based on public company peer group volatility over the contractual term of the warrants. The risk-free interest rate is based on the U.S. Treasury rate on the grant date for a maturity similar to the expected life of the warrants, which is assumed to be equivalent to their contractual term. The dividend rate is based on the historical rate, which the Company anticipates will remain at zero. The Company applied a DLOM of 20% to value its Common Stock warrants issued in connection with the New Term Facility and applied a DLOM of 30% to value its Common Stock warrants issued in connection with the Fifth Amendment.

Leases [Abstract]

LEASES

LEASESEffective in May 2021, the Company entered into a ground lease (the “Ground Lease”) related to the Lake Mariner Facility in New York with a counterparty which is a related party due to control by a member of Company management. The

Ground Lease includes fixed payments and contingent payments, including an annual escalation factor as well as the Company’s proportionate share of the landlord’s cost to own, operate and maintain the premises. The Ground Lease originally had an initial term of five years and a renewal term of five years at the option of the Company, subject to the Company not then being in default, as defined.

In July 2022, the Ground Lease was amended to increase the initial term of the lease to eight years and to amend certain other non-financial sections to adjust environmental obligations, site access rights and leasehold mortgage rights. In September 2022, the Company issued 8,510,638 shares with a fair value of $11.5 million as compensation to the landlord for entering into the lease amendment. The Ground Lease, which is classified as an operating lease, was remeasured as of the date of the amendment, resulting in an increase of $11.2 million to both right-of-use asset and operating lease liability in the consolidated balance sheets. The Ground Lease remained classified as an operating lease based on the remeasurement analysis that utilized a discount rate of 12.6%, which was an estimate of the Company’s incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at the remeasurement date. Upon expiration of the lease, the buildings and improvements on the premises will revert to the landlord in good order.

For the three and nine months ended September 30, 2023, the Company recorded operating lease expense of $0.3 million and $1.0 million, respectively, including contingent expense of $37,000 and $0.1 million, respectively, in operating expenses – related party in the consolidated statements of operations and made cash lease payments of $0.2 million and $0.8 million, respectively. For the three and nine months ended September 30, 2022, the Company recorded operating lease expense of $0.4 million and $0.5 million, respectively, including contingent expense of $0.1 million and $0.2 million, respectively, in operating expenses – related party in the consolidated statements of operations and made cash lease payments $0.1 million and of $0.2 million, respectively. The remaining lease term based on the terms of the amended Ground Lease as of September 30, 2023 is 10.6 years.

The following is a maturity analysis of the annual undiscounted cash flows of the estimated operating lease liabilities as of September 30, 2023 (in thousands):

During the nine months ended September 30, 2022, the Company entered into a short-term lease arrangement for digital currency miners. The term of the operating lease was two months and concluded in May 2022. There were no variable charges under this arrangement. For the three and nine months ended September 30, 2022, lease expense related to this arrangement of $0 and $1.3 million, respectively, was recorded in operating expenses in the consolidated statements of operations. The Company periodically enters into short term lease arrangements for operating equipment and recorded $0.1 million and $0.2 million under these short-term lease arrangements in operating expenses in the consolidated

statements of operations for the three and nine months ended September 30, 2023, respectively, and $0.3 million for each of the three and nine months ended September 30, 2022.

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

The Company’s tax provision or benefit from income taxes for interim periods is determined using an estimate of the Company’s annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. The Company has an effective tax rate of 0.0% for each of the three and nine months ended September 30, 2023 and 0.54% for each of the three and nine months ended September 30, 2022. The Company’s effective rate differs from its statutory rate of 21% primarily due to the recording of a valuation allowance against its deferred tax assets. During the three and nine months ended September 30, 2022, the Company sold the net assets held for sale of IKONICS, resulting in a reversal of existing net deferred tax liabilities and a related tax benefit of $0.3 million recorded in income tax benefit in the consolidated statements of operations during each of the three and nine months ended September 30, 2022.

ASC 740 requires a valuation allowance to reduce the deferred tax assets reported if, based on the weight of available evidence, it is more likely than not that some or a portion or all the deferred tax assets will not be realized. As of September 30, 2023 and 2022, the Company estimated a portion of its deferred tax assets will be utilized to offset the Company’s deferred tax liabilities. Based upon the level of historical U.S. losses and future projections over the period in which the remaining deferred tax assets are deductible, at this time, management believes it is more likely than not that the Company will not realize the benefits of the remaining deductible temporary differences, and as a result the Company has recorded a valuation allowance as of September 30, 2023 and December 31, 2022 for the amount of deferred tax assets that will not be realized.

The Company has no unrecognized tax benefits as of September 30, 2023 and December 31, 2022. The Company’s policy is to recognize interest accrued and penalties related to unrecognized tax benefits in tax expense. No accrued interest or penalties were recorded during the three and nine months ended September 30, 2023 and 2022.

On December 1, 2021, the Company entered into a Loan, Guaranty and Security Agreement (the “LGSA”) with Wilmington Trust, National Association as administrative agent, which consisted of an original term loan facility of $123.5 million (the “Original Term Loan”). In July 2022, the Company entered into an amendment to the LGSA (the “First Amendment”) and borrowed $15.0 million at its closing (the “First Amendment Term Loan”). In October 2022, the Company entered into a third amendment to the LGSA (the “Third Amendment”) and borrowed $7.5 million at its closing (the “Third Amendment Term Loan” and, collectively with the Original Term Loan and First Amendment Term Loan, the “Term Loans”). The Term Loans bear an interest rate of 11.5% and have a maturity date of December 1, 2024. Upon the occurrence and during the continuance of an event of default, as defined, the applicable interest rate will be 13.5%. The interest rate may be increased, if applicable, to the cash interest rate on any junior capital raised plus 8.5%, if higher. As of September 30, 2023, no interest rate adjustments had been made under this provision. Subsequent to an amendment to the LGSA in March 2023 (the “Fifth Amendment,” as described below) and as of September 30, 2023, the Company is required to pay amounts subject to an excess cash flow sweep, as defined, on a quarterly basis which will automatically extend to the maturity of the Term Loans in the event the Company repays at least $40.0 million of the principal balance of the Term Loans by April 1, 2024. If the Company does not repay at least $40.0 million of the principal balance of the Term

Loans by April 1, 2024, the Company shall repay 25.0% of the outstanding principal balance in quarterly installments beginning on April 8, 2024 through the maturity date. Interest payments were due quarterly in arrears prior to the Fifth Amendment and are due monthly in arrears subsequent to the Fifth Amendment. The Company has the option to prepay all or any portion of the Term Loans in increments of at least $5.0 million subject to certain prepayment fees for the Original Term Loan equal to (1) if paid prior to December 1, 2023, an amount of 3% of the prepaid principal and (2) if paid subsequent to December 1, 2023 but prior to the maturity date of the Term Loans, an amount of 2% of the prepaid principal. Certain events, as described in the LGSA, require mandatory prepayment. The Term Loans are guaranteed by TeraWulf Inc. and TeraCub and its subsidiaries, as defined, and is collateralized by substantially all of the properties, rights and assets of TeraWulf Inc. and its subsidiaries (except RM 101), as defined.

The LGSA, as amended, requires the Company to maintain or meet certain affirmative, negative and reporting covenants. The affirmative covenants include, among other things, a requirement for the Company to maintain insurance coverage, maintain mining equipment and comply in all material respects with the Company’s Nautilus joint venture agreement (see Note 11), each as defined. The negative covenants restrict or limit the Company’s ability to, among other things, incur debt, create liens, divest or acquire assets, make restricted payments and permit the Company’s interest in the Nautilus joint venture to be reduced below 25%, each as defined. The LGSA also contains usual and customary events of default. If an event of default occurs and is continuing, the then outstanding obligations under the LGSA may become immediately due and payable.

As of September 30, 2023 and December 31, 2022, certain of the investors in the Term Loans were related parties due to cumulative voting control by members of the Company’s management and a member of the Company’s board of directors. As of September 30, 2023 and December 31, 2022, NovaWulf Digital Master Fund, L.P. and NovaWulf Digital Private Fund, LLC, held outstanding principal balances in the amount of $2.0 million and $15.7 million, respectively. In October 2023, all outstanding principal amounts held by NovaWulf Digital Master Fund, L.P. and NovaWulf Digital Private Fund, LLC were distributed to respective entities controlled by certain limited partners of NovaWulf Digital Master Fund, L.P. and all the members of NovaWulf Digital Private Fund, LLC., of which certain are members of Company management and a member of the Company's board of directors.

In connection with the Original Term Loan, the Company issued to the holders of the Original Term Loan 839,398 shares of Common Stock (the “Term Loan Equity”), which is a quantity of Common Stock which represented 1.5% of the outstanding shares of the publicly registered shares of TeraWulf subsequent to the closing of the Original Term Loan. In connection with the issuance of the Original Term Loan, the Company incurred aggregate issuance costs of approximately $4.0 million, in addition to a $1.2 million upfront fee. The aggregate issuance costs and the upfront fee were allocated to the Term Loan Equity and the Original Term Loan based on the relative fair value method in the amounts of $1.1 million and $4.1 million, respectively. For the Original Term Loan, this $4.1 million was included in debt discount along with the fair value of the Term Loan Equity, an amount of $25.7 million. The total of these items, an amount of $29.8 million, represented debt issuance costs and debt discount and was deducted from the Original Term Loan proceeds and was being accreted into the long-term debt balance over the term of the debt at an effective interest rate of 12.9%, which was in addition to the stated interest rate.

In July 2022, the First Amendment to the LGSA provided for an additional $50.0 million term loan facility (the “New Term Facility”). Pursuant to the New Term Facility, funds could have been drawn in three tranches. The First Amendment Term Loan represented the first tranche and was drawn at closing in July 2022, and the subsequent tranches of up to $35 million (the “Delayed Draw Term Loan Commitment”) may have been drawn at Company’s option prior to December 31, 2022, subject to certain conditions, including the raising of matching junior capital, as defined. The New Term Facility required the Company to extend the initial term of the Ground Lease from five years to eight years. In connection with the New Term Facility, the Company paid an upfront fee of $0.1 million and issued warrants to the lenders under the New Term Facility to purchase 5,787,732 shares of Common Stock at $0.01 per share, an aggregate number of shares of the Company’s Common Stock equal to 5.0% (comprised of 2.0% related to the Delayed Draw Term Loan Commitment and 3.0% related to the First Amendment Term Loan) of the then fully diluted equity of the Company. In connection with the issuance of the New Term Facility, the Company also incurred aggregate issuance costs of approximately $1.5 million, in addition to the aforementioned upfront fee. If the Company drew subsequent tranches, it was required to issue warrants to the lenders to purchase shares of the Company’s Common Stock equal to dilution of 3.75% upon the issuance of a second tranche in the amount of $15.0 million and 4.25% upon issuance of a third tranche in the amount of $20.0 million, in each case as a percentage of the then fully diluted equity of the Company, respectively.

The Company determined that debt modification accounting applied in connection with the New Term Facility. Third party and upfront fees were allocated pro rata between the First Amendment Term Loan and the Delayed Draw Term Loan

Commitment. Third-party fees of $0.4 million related to the First Amendment Term loan were expensed to interest expense in the consolidated statement of operations. Fees paid to lenders and the allocated value of the Common Stock warrants, an aggregate $3.5 million, related to the First Amendment Term Loan were included with the unamortized discount on the Original Term Loan and were being amortized as an adjustment of interest expense over the remaining term of the Term Loans at an effective rate of 13.1%, which was in addition to the stated interest rate.

Fees paid and the fair value of the Common Stock warrants related to the Delayed Draw Term Loan Commitment, an aggregate $3.4 million, were capitalized to other assets (the “Commitment Fee Asset”) and were amortized on a straight-line basis over the commitment period, which expired December 31, 2022. If a tranche of the Delayed Draw Term Loan Commitment was drawn, the then related carrying value of the Commitment Fee Asset was derecognized and a discount on debt was recorded and amortized over the term of the commitment drawn.

In October 2022, the Third Amendment to the LGSA divided the initial funding of up to $15.0 million of the Delayed Draw Term Loan Commitment under the First Amendment to the LGSA into two tranches of up to $7.5 million each. The Third Amendment Term Loan represented the first tranche and was borrowed upon the closing in October 2022. In connection with the Third Amendment, the Company entered into an amendment and restatement of the warrant agreement related to the New Term Facility. The amended and restated warrant agreement provides that holders thereto are entitled to additional warrants to purchase an aggregate number of shares of Common Stock equal to an incremental 3.75%, to be divided into two separate increments of 1.875% each, of the fully diluted equity of the Company, determined on the date of the funding of the two separate sub-tranches of $7.5 million each pursuant to the Third Amendment. In connection with the Third Amendment Term Loan, the Company issued warrants to purchase 2,667,678 shares of Common Stock at $0.01 per share. The fair value of the Common Stock warrants and the related proportional carrying value of the Commitment Fee Asset, an aggregate $2.9 million, related to Third Amendment were included with the unamortized discount on the Original Term Loan and First Amendment Term Loan and were being amortized as an adjustment of interest expense over the remaining term of the Term Loans at an effective rate of 25.1%, which was in addition to the stated interest rate.

In March 2023, the Fifth Amendment to the LGSA eliminated mandatory amortization of the Term Loans through April 7, 2024, as long as the Company received aggregate net proceeds of at least $33.5 million from the issuance of equity or equity-linked securities by March 15, 2023 (such condition, the “Amortization Relief Condition”). The Company satisfied the Amortization Relief Condition on March 9, 2023. As a condition of the Fifth Amendment becoming effective, the Company entered into a warrant agreement (the “Warrant Agreement”) to issue the following warrants to the lenders: (i) 27,759,265 warrants to purchase an aggregate number of shares of the Company’s Common Stock equal to 10.0% of the fully diluted equity of the Company as of the Fifth Amendment effective date with an exercise price of $0.01 per share of the Company’s Common Stock (the “Penny Warrants”) and (ii) 13,879,630 warrants to purchase an aggregate number of shares of the Company’s Common Stock equal to 5.0% of the fully diluted equity of the Company as of the Fifth Amendment effective date with an exercise price of $1.00 per share of the Company’s Common Stock (the “Dollar Warrants”). The quantity of the Penny Warrants and the Dollar Warrants include the final impact of anti-dilution protection for additional capital raising transactions by the Company of up to $5.0 million subsequent to the $33.5 million aggregate net proceeds associated with the Amortization Relief Condition. The Penny Warrants are exercisable during the period beginning on April 1, 2024 and ending on December 31, 2025, and the Dollar Warrants are exercisable during the period beginning on April 1, 2024 and ending on December 31, 2026. In March 2023, in connection with the issuance of the warrants pursuant to the Warrant Agreement, the Company entered into a registration rights agreement pursuant to which the Company has agreed to provide customary shelf and piggyback registration rights to the LGSA lenders with respect to the common stock issuable upon exercise of the warrants described above.

The Company determined that debt modification accounting applied in connection with the Fifth Amendment. Because the First Amendment and the Fifth Amendment occurred within a twelve-month period, the debt terms that existed just prior to the First Amendment were applied in determining the appropriateness of the debt modification accounting model. The allocated value of the Penny Warrants and Dollar Warrants, an aggregate $16.0 million, related to the Fifth Amendment were included with the unamortized discount on the LGSA, as amended, and are being amortized as an adjustment of interest expense over the remaining term of the modified LGSA at an effective rate of 19.7%, which is in addition to the stated interest rate.

During the three and nine months ended September 30, 2023, the Company amortized total debt issuance costs and debt discount of $6.0 million and $16.0 million, respectively, of which $6.0 million and $14.3 million, respectively, were recorded as interest expense in the consolidated statements of operations, $0 and $1.2 million, respectively, were capitalized interest in property, plant and equipment, net in the consolidated balance sheets as of September 30, 2023 and

December 31, 2022, respectively, and $0 and $0.5 million, respectively, were capitalized interest in equity in net assets of investee in the consolidated balance sheets as of September 30, 2023 and December 31, 2022, respectively.

Principal maturities of outstanding long-term debt as of September 30, 2023 are as follows (in thousands):

STANDBY EQUITY PURCHASE AGREEMENT AND CONVERTIBLE PROMISSORY NOTE

STANDBY EQUITY PURCHASE AGREEMENT AND CONVERTIBLE PROMISSORY NOTE

Standby Equity Purchase Agreement

In June 2022, the Company entered into a Standby Equity Purchase Agreement (“SEPA”) with YA II PN, Ltd. (“Yorkville”). Pursuant to the SEPA, the Company had the right, but not the obligation, to sell to Yorkville, subject to certain limitations and conditions, up to $50.0 million of its shares of Common Stock, at the Company’s request any time during the commitment period commencing on June 2, 2022 and terminating on the earliest of (i) the first day of the month following the 36-month anniversary of the SEPA and (ii) the date on which Yorkville shall have made payment of any advances requested pursuant to the SEPA for shares of the Common Stock equal to the commitment amount of $50.0 million. In addition to the Company’s right to request advances, subject to certain conditions precedent, the Company had the option to, but was not obligated to, effect a pre-advance loan with a principal amount of $15.0 million through the issuance and sale to Yorkville of a convertible promissory note (the “Promissory Note”). The Company elected to issue and sell the Promissory Note to Yorkville on June 2, 2022. Subject to the terms of the SEPA, the Company had the right to terminate the SEPA at any time, at no cost or penalty, upon five trading days’ prior written notice so long as there are no outstanding advances, no outstanding balance on the Promissory Note and no other amounts owed to Yorkville. No termination of the SEPA affects the indemnification provisions contained within the SEPA, which provisions survive a termination. The SEPA was terminated in December 2022. No advances occurred while the SEPA was outstanding.

Yorkville Convertible Promissory Note

In June 2022, the Company issued the Promissory Note to Yorkville, which was issued with a 2.0% original issue discount, for proceeds of $14.7 million. The maturity date of the $15.0 million Promissory Note was originally November 25, 2022 and the Company was required to pay the outstanding principal balance in five monthly $3.0 million payments commencing July 27, 2022. Upon reasonable advance notice, the Company had the right to defer 50% of a monthly payment amount due on two such monthly payments to later dates to be mutually agreed by the Company and Yorkville. In July 2022, $1.5 million of the $3.0 million July monthly payment amount was deferred until the October 2022 monthly payment due date. In August 2022, $1.5 million of the $3.0 million August monthly payment amount was deferred until the November 2022 monthly payment due date. The Promissory Note, which bore an interest rate of 4.0% and had an initial conversion price of $3.75 per share of Common Stock, may have been repaid with the proceeds of a sale of Common Stock to Yorkville or repaid in cash and, if repaid in cash, together with a cash payment premium originally of 6.0%, provided that if the Company’s Common Stock market price, as defined, was less than $2.25 per share, the cash payment premium would have been 4.0%. In October and November 2022, the Company amended and restated the Promissory Note to, among other things, change the then-existing repayment schedule, change the cash payment premium to 12.0% and change the conversion price. The Company determined that extinguishment of debt accounting applied to the October 2022 amendment and restatement because the change in the fair value of the embedded conversion feature was greater than 10% of the carrying value of the Promissory Note immediately prior to the modification. The Company recorded a loss on debt extinguishment of $2.1 million in the consolidated statement of operations for the year ended December 31, 2022. This extinguishment loss was primarily related to the change in the fair value of the embedded conversion feature of $1.6 million and the excess of the fair value of the A&R Promissory Note of $9.4 million over the carrying value of the Promissory Note immediately prior to the modification. The Company determined that debt modification accounting applied to the November 2022 amendment and restatement. The $20,000 change in the fair value of the embedded conversion feature was accounted for as a debt discount and amortized as an adjustment of interest expense over the remaining term of the Second A&R Promissory Note at an effective rate of 3.1%. No portion of the Second A&R

Promissory Note was converted into shares of Common Stock and the Second A&R Promissory Note was paid in full in December 2022.

Convertible Promissory Notes

In November 2022, the Company issued convertible promissory notes (the “Convertible Notes”) in an aggregate principal amount of approximately $3.4 million to certain accredited investors, including to members of Company management in the amount of $1.7 million. The Convertible Notes were issued in privately negotiated transactions as part of a private placement exempt from registration under the Securities Act of 1933, as amended. The Convertible Notes, which contained usual and customary antidilution provisions, had a maturity date of April 1, 2025 and accrued annual interest at a rate of 4%, which would have increased to 15% upon the occurrence of an event of default, as defined. The Convertible Notes were originally automatically convertible into shares of equity securities of the Company upon the closing of a Qualified Financing, as defined in the Convertible Notes as the issuance and sale of equity securities with an aggregate gross sales price of not less than $5.0 million, with certain sales of equity securities excluded, at a conversion price equal to the price per share paid by the investors purchasing such equity securities in such Qualified Financing. The Convertible Notes originally embodied an unconditional obligation to settle a fixed monetary amount with, upon a Qualified Financing, with a variable number of shares and was initially considered potentially share settled debt. In December 2022, the Company entered into a private placement (see Note 14) which met the definition of a Qualified Financing and contemporaneously amended the Convertible Notes to (a) change the conversion date to March 1, 2023 and (b) allow for the conversion price to be reduced if an additional Qualified Financing were to occur prior to the conversion date at a price lower than the then existing Convertible Note conversion price. The Company determined that debt modification accounting applied in connection with the December 12, 2022 amendment to the Convertible Notes. There was no change to the effective interest rate as the result of this amendment. As a result of the private placement, the conversion price was $0.40 per share of Common Stock. The Convertible Notes are included in convertible promissory notes in the consolidated balance sheet as of December 31, 2022. In January 2023, the Convertible Notes were amended to change the conversion date to the third business day following the Shareholder Approval Date (as defined in Note 14). In March 2023, the Convertible Notes and accrued but unpaid interest were converted into 8,628,024 shares of Common Stock.

In January 2023, the Company entered into a convertible promissory note (the “January Convertible Note”) to an accredited investor in a privately negotiated transaction as part of a private placement exempt from registration under Section 4(a)(2) and/or Regulation D under the Securities Act in an aggregate principal amount of $1.3 million. The January Convertible Note had a maturity date of April 1, 2025 and accrued annual interest at a rate of 4.0%. The January Convertible Note was automatically convertible into Common Stock on the third business day following the Shareholder Approval Date (the “Conversion Date”) at a conversion price equal to the lowest price per share paid by investors purchasing equity securities in any sale of equity securities by the Company between November 25, 2022 and the Conversion Date with an aggregate gross sales price of not less than $5 million, subject to certain exclusions set forth in the January Convertible Note. The conversion price was $0.40 per share of Common Stock upon issuance. In March 2023, the January Convertible Note and accrued but unpaid interest were converted into 3,134,932 shares of Common Stock.

Equity Method Investments and Joint Ventures [Abstract]

JOINT VENTURE

JOINT VENTURE

In May 2021, the Company and a subsidiary of Talen Energy Corporation (“Talen”) (each a “Member” and collectively the “Members”) entered into a joint venture, Nautilus Cryptomine LLC (“Nautilus”), to develop, construct and operate up to 300 MW of zero-carbon bitcoin mining in Pennsylvania (the “Joint Venture”). In connection with the Joint Venture, Nautilus simultaneously entered into (i) a ground lease (the “Nautilus Ground Lease”), which includes an electricity supply component, with a related party of Talen, (ii) a Facility Operations Agreement (the “FOA”) with a related party of the Company and (3) a Corporate Services Agreement (the “CSA”) with a related party of Talen. Each Member originally held a 50% interest in the Joint Venture. The Company capitalized a portion of the interest on funds borrowed to finance its investments in Nautilus prior to Nautilus commencing its principal operations. Capitalized interest costs were $0 and $0.9 million for the three and nine months ended September 30, 2023, respectively, and $0 and $1.6 million for the three and nine months ended September 30, 2022, respectively. During the nine months ended September 30, 2023, the Company received bitcoin distributions from Nautilus with a fair value of $11.7 million. The Company received no bitcoin distributions in 2022.

In August 2022, the Members entered into an amended and restated Joint Venture agreement (the “A&R Agreement”) whereby, among other changes, the unit ownership will be determined by infrastructure contributions while distributions of mined bitcoin will be determined by each Member’s respective hashrate contributions. Members are allowed to make contributions of miners up to the effective electrical capacity of their owned infrastructure percentage. Each party retains

access to 50% of the electricity supply outlined in the Nautilus Ground Lease. Additionally, the Company’s scheduled capital contributions were amended such that the Company would retain a 33% ownership interest in the Joint Venture if such capital contributions were funded. With the change in ownership percentage, governance rights were amended to provide for greater Talen board participation, among other changes. As allowed under the A&R Agreement, the Company structured its capital contributions to achieve a targeted a 25% ownership interest in Nautilus.

In March 2023, the Company entered into a second amended and restated limited liability company agreement for Nautilus (the “Second A&R Nautilus Agreement”). Under the Second A&R Nautilus Agreement, the Company holds a 25% equity interest in Nautilus and Talen holds a 75% equity interest in Nautilus, each subject to adjustment based on relative capital contributions. Distributions are made periodically in accordance with each Member’s respective hashrate contributions after deducting primarily each Member’s share of power and operational costs. Pursuant to the terms of the Second A&R Nautilus Agreement, the Nautilus Cryptomine Facility initially requires 200 MW of electric capacity. Prior to May 13, 2024, the Company may elect to expand the energy requirement of the Nautilus Cryptomine Facility by up to 50 MW, funded solely by the Company. If the Company makes such an election, the Talen Member may, within twelve months thereof, elect to expand the energy requirement of the Nautilus Cryptomine Facility by up to an additional 50 MW, funded solely by the Talen Member, for a total capacity of up to 300 MW. Upon such election, Nautilus will call additional capital for expansion and enter into an additional energy supply agreement with Talen Member or its affiliate for the additional capacity, subject to any regulatory approvals and third-party consents.

In March 2021, TeraCub executed an agreement for the purchase of bitcoin miners from MinerVA Semiconductor Corp. (“MinerVA”) for a total of 30,000 MV7 miners, with originally scheduled monthly deliveries of miners each between November 2021 and January 2022, for an aggregate price of $118.5 million (the “MinerVA Purchase Agreement”). Concurrently with the execution of the Joint Venture agreement, TeraWulf assigned the MinerVA Purchase Agreement to Nautilus. Prior to December 31, 2022, total payments of $40.5 million were made under the MinerVA Purchase Agreement. Production delays at MinerVA’s factory impacted the initial pricing and delivery schedule. Accordingly, Nautilus and MinerVA have deemed all payments made to date to apply to the initial approximate 9,000 miners shipped or to be shipped. As of the date at which these financial statements were available to be issued, Nautilus had not amended the MinerVA Purchase Agreement.

In June 2021, Nautilus entered into two Non-fixed Price Sales and Purchase Agreements for the purchase of bitcoin miners from Bitmain Technologies Limited (“Bitmain”) for a total of 30,000 S19j Pro miners, with originally scheduled monthly deliveries of 5,000 miners each between January 2022 and March 2022 under one agreement (the “Q1 2022 Bitmain Agreement’) and 5,000 miners each between April 2022 and September 2022 under a second agreement (the “Q2 2022 Bitmain Agreement” and, together, the “Bitmain Purchase Agreements”). During the nine months ended September 30, 2022, the Company paid Bitmain $22.8 million and was reimbursed by Talen for 50% of that amount. As of December 31, 2022, the Q1 2022 Bitmain Agreement was concluded with all parties performing under the contract. In September 2022, the Q2 2022 Bitmain Agreement was cancelled whereby each Member received a $31.2 million credit with Bitmain to use at the respective Member’s discretion (the “Bitmain Credit”). See Note 12. The Company recorded a distribution from the Joint Venture whereby equity in net assets of investee was reduced and property, plant and equipment, net was correspondingly increased by the $31.2 million distributed credit in the consolidated balance sheet as of December 31, 2022.

In December 2022, the Company entered into a Payment Netting Agreement with Nautilus, Talen and the related party FOA and CSA agreement counterparties whereby certain amounts were owed by Nautilus to each of the FOA and CSA counterparties, including for the termination of the FOA agreement. These amounts were offset to arrive at a net result whereby the Company owed the related party FOA counterparty (see Note 16) approximately $2.2 million. This amount is recorded in equity in net assets of investee in the consolidated balance sheet as of December 31, 2022.

The Company’s direct payments to MinerVA and Bitmain, among others, on behalf of Nautilus for the nine months ended September 30, 2022, are included in investments in joint venture related to direct payments made on behalf of joint venture

in the consolidated statement of cash flows. A reconciliation of amounts included within this footnote to captions in the consolidated statements of cash flows for the nine months ended September 30, 2023 and 2022 follows (in thousands):

Nautilus is a VIE accounted for using the equity method of accounting. The table below summarizes the Company’s interest in Nautilus and the Company’s maximum exposure to loss as a result of its involvement with the VIE as of September 30, 2023 (in thousands, except for percentages):

	%		Initial Investment		Additional Investment, Net		Net loss Inception to Date		Company’s Variable Interest in Entity		Commitment to Future Additional Contributions (1)		Company’s Maximum Exposure to Loss in Entity (2)
Entity	Ownership
Nautilus	25.0	%	$	18,000	$	117,420	$	29,863	$	105,557	$	—	$	105,557

(1)The Members may mutually agree on changes to the Nautilus facility, which could increase the amount of contributions the Company is required to provide. The Members may seek alternate financing for the Nautilus facility, which could reduce the amount of investments each Member may be required to provide.

(2)The maximum exposure at September 30, 2023 is determined by adding the Company’s variable interest in the entity and any explicit or implicit arrangements that could require the Company to provide additional financial support. The amount represents the contractually required capital contributions of the Company which were required for the initial phase of the Nautilus facility buildout.

Due to the change in Member ownership percentage and governance rights under the A&R Agreement, Talen determined it controlled the Joint Venture from an accounting perspective and thereby was required to fair value the identifiable assets and liabilities of the Joint Venture for its internal accounting purposes. Under the CSA, Talen is responsible for maintaining the books and records of the Joint Venture and elected to push down the fair value adjustments to Nautilus’ books and records. During the nine months ended September 30, 2023, Talen elected to push down an additional fair value adjustment to Nautilus’ books and records. The Company accounts for the Joint Venture as an equity method investment and the change in ownership percentage does not impact the Company’s method of accounting or basis. Therefore, there is a basis difference between the books and records of Nautilus and the Company’s accounting basis in the Joint Venture. The

condensed results of operations for the three and nine months ended September 30, 2023 and 2022 and the condensed financial position as of September 30, 2023 and December 31, 2022 of Nautilus are summarized below (in thousands):

(1)The condensed statement of operations information for the three and nine months ended September 30, 2023 and 2022 and the condensed balance sheet information as of September 30, 2023 and December 31, 2022 reflect the impact of the Talen-estimated fair value measurements of Nautilus which, resulting from the application of ASC 805 “Business Combinations,” have been pushed down to the books and records of Nautilus by Talen, as discussed above. The Company’s basis in the assets and liabilities of Nautilus continue to be recorded at historical value on the accompanying consolidated balance sheets.

In March 2022, the Company entered into an exchange agreement with Nautilus and the Nautilus co-venturer whereby the Company purchased 2,469 of Nautilus’ Bitmain S19j Pro miners (the “Nautilus Miners”) to be received under the Bitmain Purchase Agreements in exchange for an option to either (1) deliver miners that are not less favorable in all material respects to those of the Nautilus Miners (the “Exchange Miners”) by July 1, 2022 or (2) incur a pro forma adjustment to Nautilus’ distributions such that the Nautilus co-venturer is made whole as though the miners had not been transferred to the Company. If the Exchange Miners were not delivered by September 30, 2022, the Nautilus co-venturer would have been entitled to elect to distribute in-kind a number of miners then in possession of Nautilus comparable to the then-undelivered Exchange Miners. During the nine months ended September 30, 2022, the Nautilus Miners were received and recorded at fair value to property, plant and equipment, net in the amount of $16.0 million with a corresponding recognition of an exchange miner liability of the same amount. The A&R Agreement removed the Company’s obligation to deliver the Exchange Miners to the Joint Venture. Accordingly, the Company derecognized the miner exchange liability and recorded a $16.8 million reduction in equity in net assets of investee in the consolidated balance sheet as of December 31, 2022 and recorded a loss on nonmonetary miner exchange of $0.8 million in the consolidated statement of operations for the three and nine months ended September 30, 2022.

In September 2022, the Company, as allowed under the A&R Agreement and because its Lake Mariner Facility was operational, transferred 2,500 Bitmain S19j Pro miners from Nautilus to its Lake Mariner Facility. Accordingly, the Company recorded the miners at an estimated fair value of $4.8 million, determined based on a contemporaneous observed market price for identical assets, in property, plant and equipment, net and the Company reduced the equity in net assets of investee balance by $16.3 million, the book value of the miners in Nautilus’ books and records, in the consolidated balance sheet as of December 31, 2022 and recorded a loss of $11.5 million as a component of equity in net loss of investee, net of tax in the consolidated statements of operations for the three and nine months ended September 30, 2022.

In February, March and April 2023, the Company, as allowed under the A&R Agreement, transferred control of approximately 4,900 MinerVA miners from Nautilus to its Lake Mariner Facility, including certain miners that have yet to be shipped from MinerVA. Accordingly, the Company recorded the miners at an estimated fair value of $6.9 million, determined based on a contemporaneous observed market price for similar assets, in property, plant and equipment, net and the Company reduced the equity in net assets of investee balance by $20.5 million, the book value of the miners in Nautilus’ books and records, in the consolidated balance sheet as of September 30, 2023 and recorded a loss of $0 and $13.6 million as a component of equity in net loss of investee, net of tax in the consolidated statements of operations for the three and nine months ended September 30, 2023, respectively.As contemplated in the A&R Agreement, members are allowed to make contributions of miners up to the effective electrical capacity of their owned infrastructure percentage. During the nine months ended September 30, 2023 and the year ended December 31, 2022, the Company contributed to Nautilus certain miners with a fair value, determined based on miner vendor contracts, of $36.7 million and $11.6 million, respectively. Accordingly, as of September 30, 2023 and December 31, 2022, the Company increased the equity in net assets of investee balance by $36.7 million and $11.6 million, respectively, and reduced the property, plant and equipment, net balance by the same amounts in the consolidated balance sheets.

CONVERTIBLE PREFERRED STOCK

TeraWulf Convertible Preferred Stock

In March 2022, TeraWulf entered into Series A Convertible Preferred Stock Subscription Agreements (the “Subscription Agreements”) with certain accredited and institutional investors (collectively, the “Holders”). Pursuant to the Subscription Agreements, the Company sold 9,566 shares (of 10,000 shares authorized) of Series A Convertible Preferred Stock, par value $0.001 per share (the “Convertible Preferred Stock”) to the Purchasers for an aggregate purchase price of $9.6 million. The Subscription Agreements contain customary representations, warranties, covenants and agreements of the Company. The offer and sale of the Convertible Preferred Stock were made pursuant to the prospectus and prospectus supplement forming a part of the 2022 Registration Statement.

Holders of the Convertible Preferred Stock will accumulate cumulative dividends at an annual rate of 10.0% on the stated amount per share plus the amount of any accrued and unpaid dividends on such share, accumulating on a daily basis and payable quarterly on March 31st, June 30th, September 30th and December 31st, respectively, in each year and commencing June 30, 2022. Commencing June 30, 2022, unpaid dividends will be accreted to the liquidation preference. The initial liquidation preference is $1,000 per share. Holders of the Convertible Preferred Stock will also be entitled to such dividends paid to holders of the Company’s Common Stock, if applicable, as if such holders of the Convertible Preferred Stock had converted their Preferred Shares into Common Stock (without regard to any limitations on conversions) and had held such shares of the Company’s Common Stock on the record date for such dividends and distributions. If applicable, such payments will be made concurrently with the dividend or distribution to the holders of the

Company’s Common Stock. Upon liquidation, the Convertible Preferred Stock will rank senior to the Company’s Common Stock, and will have the right to be paid, out of the assets of the Company legally available for distribution to its stockholders, an amount equal to the Liquidation Preference (as defined in the Company’s Series A Convertible Preferred Certificate of Designations) per share of the Convertible Preferred Stock. Holders of Convertible Preferred Stock will not generally have the right to vote at any meeting of stockholders, except for certain protective voting rights, as defined. The Convertible Preferred Stock does not have a maturity date.

The Holders of the Convertible Preferred Stock will have a right to effect an optional conversion of all or any whole number of shares of the Convertible Preferred Stock at any time and from time to time. The Company will have a right to effect a mandatory conversion of the Convertible Preferred Stock after the third anniversary of the issuance date if the Last Reported Sale Price (as defined in the Company’s Series A Convertible Preferred Certificate of Designations) per share of Common Stock exceeds 130% of the Conversion Price, as defined, on each of at least five (5) trading days (whether or not consecutive) during the fifteen consecutive trading days ending on, and including, the trading day immediately before the mandatory conversion notice date for such mandatory conversion. The number of shares of Common Stock issuable upon conversion will be equal to the liquidation preference, including accumulated and unpaid dividends, divided by the Conversion Price, as defined. The Conversion Price is determined by dividing $1,000 by the Conversion Rate, as defined, which is initially 100 shares of Common Stock per $1,000 liquidation preference of Convertible Preferred Stock. The Conversion Rate will be adjusted for certain customary events, including (but not limited to) stock dividends, stock splits or combinations, tender offers or exchange offers and, additionally, for Fundamental Changes, as defined, to include (but are not limited to) a change in control of the Company, disposition of substantially all assets of the Company, the Company’s Common Stock holders approve a plan of liquidation or dissolution or the Company’s Common Stock cease to be listed on the Nasdaq Capital Market. A Fundamental Change will adjust the Conversion Rate based on the date of the Fundamental Change and the Stock Price, as defined, on such date. The Conversion rate will not exceed 125 shares of Common Stock per $1,000 liquidation preference of Convertible Preferred Stock. If any Convertible Preferred Stock is to be converted pursuant to a Holder’s optional conversion, the Company will have the option to settle such conversion in cash, as defined.

No dividends were paid during the nine months ended September 30, 2023 and 2022. Cumulative dividends of $1.6 million were accumulated and accreted to liquidation preference as of September 30, 2023. As of September 30, 2023, the aggregate liquidation preference of the Convertible Preferred Stock was approximately $11.1 million. If the entire liquidation preference of the Convertible Preferred Stock was converted at the Conversion Price, the Company would issue approximately 1.1 million shares of Common Stock.

In October 2022, the Company entered into unit subscription agreements with certain accredited investors in privately negotiated transactions (collectively, the “October Purchasers”) as part of a private placement (the “October Private Placement”) exempt from registration under the Securities Act of 1933, as amended. Pursuant to the Unit Subscription Agreements, the Company sold 7,481,747 units, each consisting of one share of the Common Stock and one warrant (the “October Warrants”), exercisable at a price of $1.93 per Common Share, to the October Purchasers for an aggregate purchase price of approximately $9.4 million based on an offering price equal to the trailing 10-day volume weighted price of $1.26 for each Common Share plus one warrant. Approximately $3.5 million of the aggregate purchase price related to investments by entities controlled by members of Company management. In connection with the Unit Subscription Agreements, the Company and the October Purchasers entered into a Registration Rights Agreement, pursuant to which the Company agreed to provide customary shelf and piggyback registration rights to the October Purchasers with respect to the shares of Common Stock underlying the October Warrants. The Company allocated the proceeds between the Common Stock and the October Warrants based on the relative fair values of the financial instruments, with $5.1 million allocated to the Common Stock and $4.3 million allocated to the October Warrants. In January 2023, certain of these investors agreed to amend the terms of their October Warrants such that their warrants would become exercisable only after the Shareholder Approval Date.

In December 2022, the Company entered into subscription agreements or unit subscription agreements with certain accredited and institutional investors in privately negotiated transactions (the “December Purchasers”) as part of a private placement (the “December Private Placement”) exempt from registration under the Securities Act of 1933, as amended.

The December Warrants became exercisable on January 16, 2023 and expired on January 31, 2023. In connection with the issuance of the December Warrants, the Company and the December Purchasers entered into a Registration Rights Agreement, pursuant to which the Company agreed to provide customary shelf and piggyback registration rights to the December Purchasers with respect to the shares of Common Stock underlying the December Warrants. The Company allocated the proceeds between the Common Stock and the December Warrants based on the relative fair values of the financial instruments, with $5.4 million allocated to the Common Stock and $1.3 million allocated to the December Warrants.

In January 2023, the Company entered into additional subscription agreements with certain December Purchasers pursuant to which such December Purchasers purchased from the Company shares of Common Stock, at a purchase price of $0.40 per share of Common Stock, in private placement transactions

exempt from registration under Section 4(a)(2) and/or Regulation D under the Securities Act for an aggregate purchase price of $1.8 million (the “January Private Placement”). The January Private Placement effectively replaced the then 50% unexercised December Warrants at the same purchase price of $0.40 per share of Common Stock. The closing of the January Private Placement was subject to certain conditions, including the completion of a $30 million equity capital raise by the Company, which may have been unilaterally waived by the December Purchasers, and the receipt of shareholder approval of an increase to issued and unauthorized shares of Common Stock. Pursuant to these Common Stock subscription agreements, the Company agreed to provide customary registration rights to the certain December Purchasers.

The Warrant Agreements governed the terms and conditions of the January 2023 Warrants, which were exercisable beginning on the first business day following the date on which shareholder approval of an increase in the Company’s authorized Common Stock was obtained, which occurred on the Shareholder Approval Date, and would have expired on December 31, 2023. The Warrant Investors are entitled to customary registration rights with respect to the shares of common stock issuable upon exercise of the Warrant Subscription Agreements.

The New Exchange Warrants were exercisable at a strike price of $0.0001 per share beginning on the first business day following the date on which shareholder approval of an increase in the Company’s authorized Common Stock was obtained, which occurred on the Shareholder Approval Date, and would have expired on December 31, 2023. The Exchanging Shareholder is entitled to customary registration rights with respect to the shares of common stock issuable upon exercise of the New Exchange Warrants. The Exchange Agreement contains customary representations, warranties, covenants and is subject to customary closing conditions and termination rights. The New Exchange Warrants were exercised and 12,000,000 shares of Common Stock were issued in April 2023.

In February 2023, the Company commenced an underwritten public offering of 36,764,706 shares of Common Stock at $0.68 per share (the “Offering”). JonesTrading Institutional Services LLC, as representative of the several underwriters (the “Underwriters”) and pursuant to an underwriting agreement (the “Underwriting Agreement”), acted as book-running manager for the Offering. The Underwriting Agreement includes customary representations, warranties and covenants by the Company and customary conditions to closing, obligations of the parties and termination provisions. Additionally, under the terms of the Underwriting Agreement, the Company agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments the Underwriters may be required to make in respect of these liabilities. Pursuant to the Underwriting Agreement, the Company granted the Underwriters a 30-day over-allotment option to purchase up to an additional 5,514,705 shares of its Common Stock, of which the Underwriters elected to purchase 4,000,000 of the over-allotment prior to the close of the Offering.

In May 2021, the Company made effective the 2021 Omnibus Incentive Plan (the “Plan”) for purpose of attracting and retaining employees, consultants and directors of the Company and its affiliates by providing each the opportunity to acquire an equity interest in the Company or other incentive compensation in order to align the interests of such individuals with those of the Company’s stockholders. The Plan provides for a maximum number of shares to be issued, limitations of shares to be delivered for incentive stock options and a maximum compensation amount for any non-employee member of the board of directors, among other provisions. The form of grants under the Plan includes stock options, stock appreciation rights, restricted stock and RSUs. Additionally, during the three and nine months ended September 30, 2023 the Company issued 20,715 and 341,503 shares of Common Stock, respectively, to Board of Director members for payment of quarterly fees in lieu of cash payments.

RELATED PARTY TRANSACTIONS	9 Months Ended
	Sep. 30, 2023
Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONSIn April 2021, the Company entered into an Administrative and Infrastructure Services Agreement (the “Services Agreement”) with Beowulf Electricity & Data Inc. (“Beowulf E&D”), a related party due to control by a member of Company management. Under the Services Agreement, Beowulf E&D will provide, or cause its affiliates to provide, to TeraWulf certain services necessary to construct and operate certain bitcoin mining facilities developed or anticipated to be developed by the Company and support the Company’s ongoing business, including, among others, services related to construction, technical and engineering, operations and maintenance, procurement, information technology, finance and accounting, human resources, legal, risk management and external affairs consultation. The Services Agreement has an initial term of five years and provides for certain fixed, passthrough and incentive payments to Beowulf E&D, including issuing to certain designated employees of Beowulf E&D awards with respect to shares of TeraWulf Common Stock upon the consummation of an initial public offering of TeraWulf or the consummation of a merger following which TeraWulf is listed on a nationally recognized securities exchange and, thereafter, upon achievement of certain milestones regarding bitcoin mining capacity deployed at the bitcoin mining facilities. For the base fee, the Company originally agreed to pay Beowulf E&D in monthly installments an annual fee for the first year in the amount of $7.0 million and, thereafter, an annual fee equal to the greater of $10.0 million or $0.0037 per kilowatt hour of electric load utilized by the bitcoin mining facilities. In March 2023, TeraWulf and Beowulf E&D entered into an Amendment No. 1 to the Services Agreement, pursuant to which TeraWulf agreed to pay Beowulf E&D, effective as of January 1, 2023, a reduced annual base fee equal to $8.5 million payable in monthly installments, until all obligations under the Company’s LGSA, as amended and restated from time to time, are either indefeasibly repaid in full or refinanced. The Services Agreement also provides for reimbursement of cost and expenses incurred in connection with providing the services. For the nine months ended September 30, 2023 and 2022, the Company paid Beowulf E&D $16.4 million and $11.0 million, respectively, under the Services Agreement, including payments related to construction agreements with contractors at the Lake Mariner Facility. For the three and nine months ended September 30, 2023, selling, general and administrative expenses – related party in the consolidated statements of operations includes $4.5 million and $10.1 million, respectively, and operating expenses – related party in the consolidated statements of operations includes $0.5 million and $1.0 million, respectively, in each case related to the base fee and reimbursement of costs and expenses. For the three and nine months ended September 30, 2022, selling, general and administrative expenses – related party in the consolidated statements of operations includes $3.0 million and $8.2 million, respectively, and operating expenses – related party in the consolidated statements of operations includes $0.1 million and $0.3 million, respectively, in each case related to the base fee and reimbursement of costs and expenses. As of September 30, 2023, $0.7 million is included in prepaid expenses, $1.4 million is included in other amounts due to related parties and $7.1 million is included in property, plant and equipment, net in the consolidated balance sheet. As of December 31, 2022, $0.8 million is included in prepaid expenses, $3.0 million, including $2.2 million related to the Payment Netting Agreement, is included in amounts due to related parties and $5.9 million is included in property, plant and equipment, net in the consolidated balance sheet.The Services Agreement also provides for performance related milestones and related incentive compensation. In connection with the listing of its Common Stock on a nationally recognized stock exchange in December 2021, pursuant to the Services Agreement, the Company agreed to issue awards valued at $12.5 million with respect to shares of its Common Stock to certain designated employees of Beowulf E&D in accordance with TeraWulf’s then effective Plan. Once the mining facilities have utilized 100 MW of cryptocurrency mining load in the aggregate, and for every incremental 100 MW of cryptocurrency mining load deployed thereafter, TeraWulf agreed to issue additional awards of shares of TeraWulf Common Stock each in the amount of $2.5 million to certain designated employees of Beowulf E&D in accordance with TeraWulf’s then effective Plan. As of December 31, 2022, the Company considered it probable that the first performance milestone of 100 MW of mining load deployed by the mining facilities would be met, and it was met in April 2023. In September 2023 the Company and Beowulf E&D agreed to settle the $15.0 million share based liabilities due to related party by issuing 2,460,513 shares of the Company's Common Stock with a fair value of $3.4 million and the Company recorded the remaining reduction to the share based liabilities due to related party of $11.6 million to additional paid-in capital during each of the three and nine months ended September 30, 2023. As of September 30, 2023, the Company considered it probable that the second performance milestone of incremental 100 MW of mining load deployed by the mining facilities will be met. Accordingly, the Company recognized $2.1 million in expense during each of the three and nine months ended September 30, 2023, which is included within selling, general and administrative expense – related party in the consolidated statements of operations and recognized corresponding share based liabilities due to related party in the consolidated balance sheet. As of September 30, 2023 and December 31, 2022, $2.1 million and $14.6 million, respectively, are included in share based liabilities due to related party in the consolidated balance sheets.

SIGNIFICANT ACCOUNTING POLICIES (Policies)

9 Months Ended

Sep. 30, 2023

Accounting Policies [Abstract]

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

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.

Prior Interim Period Restatement

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.

Use of Estimates in the Financial Statements

Use of Estimates in the Financial Statements

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.

Cash and Cash Equivalents

Cash and Cash Equivalents

Highly liquid instruments with an original maturity of three months or less are classified as cash equivalents. As of September 30, 2023 and December 31, 2022, the Company had cash and cash equivalents of $6.6 million and $8.3 million, including restricted cash, respectively.

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.

Restricted Cash

Restricted CashThe 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).

Segment Reporting

Segment Reporting

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

Property, Plant and Equipment

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.

Impairment of Long-lived Assets

Impairment of Long-lived AssetsThe 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.

Leases

Leases

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.

As of September 30, 2023 and December 31, 2022, the Company was not a counterparty to any finance leases.

Debt Modification

Debt Modification

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

consolidated statements of operations. Amounts paid by the Company to the lenders, including upfront fees and the fair value of warrants issued, are included in future cash flows for accounting treatment determination and, if debt modification is applicable, are also included in the determination of yield adjustment.

Convertible Instruments

Convertible Instruments

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.

Warrants

Warrants

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.

Nonmonetary Transactions

Nonmonetary Transactions

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.

Stock Issuance Costs

Stock Issuance Costs

Stock issuance costs are recorded as a reduction to issuance proceeds. Stock issuance costs incurred prior to the closing of the related issuances, including under shelf registration statements, are recorded in other assets in the consolidated balance sheets if the closing of the related issuance is deemed probable.

Held for Sale and Discontinued Operations Classification

Held for Sale and Discontinued Operations Classification

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.

Revenue Recognition

Revenue Recognition

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:

•Step 1: Identify the contract with the customer

•Step 2: Identify the performance obligations in the contract

•Step 3: Determine the transaction price

•Step 4: Allocate the transaction price to the performance obligations in the contract

•Step 5: Recognize revenue when the Company satisfies a performance obligation

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).

If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.

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

•Constraining estimates of variable consideration

•The existence of a significant financing component in the contract

•Noncash consideration

•Consideration payable to a customer

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.

Mining Pool

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.

There is no significant financing component in these transactions.

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.

Consideration payable to the customer in the form of a pool operator fee, which is incurred only to the extent that the Company has generated FPPS consideration, is deducted from the bitcoin the Company receives and is recorded as contra-revenue, as it does not represent a payment for a distinct good or service.

Data Center Hosting

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.

Digital currency, net

Digital currency, net

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.

Cost of Revenue

Cost of Revenue

Cost of revenue for mining pool revenue is comprised primarily of direct costs of electricity but excludes depreciation which is separately presented. Cost of revenue for data center hosting is comprised primarily of direct costs of electricity, labor and internet provision.

Stock-based Compensation

Stock-based Compensation

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.

Power Curtailment Credits

Power Curtailment CreditsProceeds 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.

Other Income

Other Income

Other income consists primarily of interest income on bank deposits. The Company recorded other income of $0 and $39,000 during the three and nine months ended September 30, 2023, respectively, related to a disgorgement of short-swing profits arising from trades by a non-management insider under Section 16(b) of the Securities and Exchange Act of 1934.

Loss per Share

Loss per Share

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.

Concentrations

Concentrations

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.
