Current report

On May 21, 2025 (the “Acquisition Date”), the Company acquired 100% of the membership interests in Beowulf Electricity & Data LLC, Beowulf E&D (MD) LLC, and Beowulf E&D (NY) LLC (collectively, “Beowulf E&D”). The fair value of total consideration for the transaction was approximately $54.6 million, including $3.0 million in cash and 5.0 million shares of the Company’s common stock (“Common Stock”) issued on the Acquisition Date. The purchase agreement also includes up to $19.0 million in contingent cash payments and up to $13.0 million in additional Common Stock, subject to the achievement of key milestones related to the expansion of the Company’s data center business and project financing initiative. As part of the acquisition, 94 employees of Beowulf E&D, including site staff at the Lake Mariner Facility and corporate personnel, were transitioned to TeraWulf. In addition, the existing Administrative and Infrastructure Services Agreement (the “Services Agreement”) with Beowulf E&D was terminated on the Acquisition Date.

Current report

In July 2025, the CB-1 Earnout Milestone was achieved and the Company paid $6.0 million in cash and issued 1.8 million shares of Common Stock to the Seller valued at $6.5 million, calculated on the basis of a 60-day trailing VWAP as of the date the CB-1 Earnout Milestone was achieved.

Current report

Revenue for the three months ended June 30, 2025 and 2024 was $47.6 million and $35.6 million, respectively, representing an increase of $12.0 million. Revenue for the six months ended June 30, 2025 and 2024 was $82.0 million and $78.0 million, respectively, representing an increase of $4.0 million. These increases were primarily due to the increase in average bitcoin prices during the periods, partially offset by a decrease in total bitcoin mined during the periods. Although the Company expanded its mining infrastructure capacity, due to the halving in April 2024 as well as an increase in network difficulty, the Company mined 485 and 857 bitcoin during the three and six months ended June 30, 2025, respectively, compared to 699 and 1,750 bitcoin during the same three and six month period in the prior year, respectively.

Current report

Bitcoin prices averaged $98,434 and $95,992 per bitcoin during the three and six months ended June 30, 2025, respectively, as compared to $65,771 and $59,515 per bitcoin during the three and six months ended June 30, 2024, respectively.

Current report

Selling, general and administrative expenses (including related party expenses) for the three months ended June 30, 2025 and 2024 were $14.3 million and $11.9 million, respectively, an increase of $2.4 million which was primarily due to the $2.4 million performance milestone expense under the Services Agreement during the three months ended June 30, 2025.

Current report

Change in fair value of contingent consideration was $1.6 million during the three and six months ended June 30, 2025 related to fair value remeasurement of contingent consideration liabilities for the acquisition of Beowulf E&D as of June 30, 2025.

Current report

Loss on disposals of property, plant, and equipment was $3.8 million during the three and six months ended June 30, 2025, due to 2,918 miner sold or otherwise disposed in May and June 2025 for proceeds of $1.9 million. No miners were sold or otherwise disposed during the three and six months ended June 30, 2024.

Current report

Interest expense during the three months ended June 30, 2025 and 2024 was $4.0 million and $5.3 million, respectively, a decrease of $1.3 million. The decrease is primarily attributed to $0.6 million of amortization of debt issuance costs for the 2030 Convertible Notes during the three months ended June 30, 2025 as compared to $3.1 million of amortization for the LGSA during the three months ended June 30, 2024. Interest expense during six months ended June 30, 2025 and 2024 was $8.1 million and $16.4 million, respectively, a decrease of $8.3 million. The decrease is primarily attributed to $1.2 million of amortization of debt issuance costs for to the 2030 Convertible Notes during the six months ended June 30, 2025 as compared to $10.7 million of amortization for the LGSA during six months ended June 30, 2024. The decrease is further driven by the lower stated interest rates, during three and six months ended June 30, 2025 and 2024, respectively.

Current report

Interest income during the three months ended June 30, 2025 and 2024 was $1.2 million and $0.4 million, respectively, an increase of $0.8 million. Interest expense during the six months ended June 30, 2025 and 2024 was $3.5 million and $0.9 million, respectively. These increase were primarily due to an increase of interest earned on higher average cash balances during the three and six months ended June 30, 2025 as compared to the three and six months ended June 30, 2024.

Current report

Assets Acquired and Liabilities Assumed in a Business Combination

Previous report

On May 5, 2025, the Company held its 2025 Annual Meeting of Stockholders (the “2025 Annual Meeting”). As a result of the matters submitted to a stockholder vote at the 2025 Annual Meeting, the Company's stockholders adopted a Plan amendment increasing the maximum number of shares available for issuance under the Plan to 54,096,290 shares of Common Stock and increasing the number of shares of Common Stock authorized for issuance for grants of incentive stock options to 13,524,073 shares of Common Stock.

Previous report

Revenue for the three months ended March 31, 2025 and 2024 was $34.4 million and $42.4 million, respectively, a decrease of $8.0 million. The decline was primarily due to a reduction in the total bitcoin mined driven by the April 2024 halving event and increased network hashrate. As a result, the Company mined a total of 372 bitcoin during the three months ended March 31, 2025 as compared to 767 bitcoin during the same period in the prior year. This decrease was partially offset by a higher average price of bitcoin of $93,522 during the three months ended March 31, 2025, compared to $53,260 in the prior year period, as well as increased mining capacity at the Lake Mariner Facility between March 31, 2024 and 2025.

Previous report

Interest expense was $4.0 million and $11.0 million for the three months ended March 31, 2025 and 2024, respectively, a decrease of $7.0 million. The decrease is primarily attributed to amortization of debt issuance costs during the three months ended March 31, 2025 related to the 2030 Convertible Notes of $0.6 million as compared to $7.6 million during the three months ended March 31, 2024 related to the LGSA which was fully repaid in July 2024 ahead of maturity.

Previous wording

Power costs are the most significant expense in our bitcoin mining operations, accounting for 71.4% and 28.8% of the total value of bitcoin mined for the three months ended March 31, 2025 and 2024, respectively. The increase in power costs as a percentage of bitcoin mined for the three months ended March 31, 2025 as compared to 2024 was primarily driven by a near doubling of network difficulty and the bitcoin reward halving in April 2024, which reduced block rewards. These impacts were partially offset by growth in our average operating hashrate and an increase in the average market value of each bitcoin mined.

Current wording

Power costs are the most significant expense in our bitcoin mining operations, accounting for 46.4% and 56.9% of the total value of bitcoin mined for the three and six months ended June 30, 2025, respectively, and 34.8% and 31.5% for the three and six months ended June 30, 2024, respectively. The increase in power costs as a percentage of bitcoin mined for the three and six months ended June 30, 2025 as compared to 2024 was primarily driven by a near doubling of network difficulty and the bitcoin reward halving in April 2024, which reduced block rewards. The increase in three and six months ended June 30, 2025 is also driven by historically high power prices in the first quarter of 2025. These impacts were partially offset by growth in our average operating hashrate and an increase in the average market value of each bitcoin mined.

Previous wording

Energy prices are highly volatile, influenced by global events that can drive nationwide fluctuations in power costs. At the Lake Mariner Facility, power costs are subject to variable market rates, which can change hourly based on wholesale electricity pricing. While this introduces some unpredictability, it also provides us with the flexibility to actively manage our energy consumption, optimizing for profitability and efficiency. Energy prices are also highly sensitive to weather conditions, such as winter storms, which can increase regional power demand and drive up costs. During such events, we may curtail operations to avoid consuming power at peak rates, or we may be curtailed under demand response programs in which we participate. The average aggregate realized power prices at the Lake Mariner Facility and the Nautilus Cryptomine Facility were $0.081 and $0.041 per kWh during the three months ended March 31, 2025 and 2024, respectively.

Cash provided by operating activities was $56.5 million and $22.8 million for the three months ended March 31, 2025 and 2024, respectively. The increase in 2025 was primarily driven by the receipt of $90.0 million in Prepaid Rent from the Company’s HPC customer. These amounts are reflected in the condensed consolidated balance sheet as of March 31, 2025 within the current and non-current portions of deferred rent liability, totaling $32.0 million and $58.0 million, respectively. This increase was partially offset by a $10.1 million rise in cost of revenue during the 2025 period compared to the prior year. Cost of revenue, which primarily consists of power expenses, increased due to expanded mining and hosting capacity, the effects of the April 2024 halving and increased network hashrate, and higher realized power prices. Additionally, prior to the repayment of its Term Loans in July 2024, the Company converted bitcoin to cash almost immediately. As a result, $54.4 million in proceeds from digital currency sales were included in operating cash flows for the three months ended March 31, 2024.

Digital currency consists of bitcoin earned as noncash consideration for providing hash computation services to a mining pool. Digital currency is classified as an intangible asset with indefinite useful life and presented as a current asset on the condensed consolidated balance sheets, based on the Company’s ability to sell bitcoin in a highly liquid market and its expectation to convert these holdings to cash within the next twelve months. Effective January 1, 2024, the Company early adopted ASU 2023-08, which requires digital assets to measured at fair value each reporting period in accordance with ASC 820, with changes in fair value recognized as net income. Gains and losses from the remeasurement of digital currency are recorded in “gain on fair value of digital currency, net” within the consolidated statements of operations. Similarly, realized gains and losses from bitcoin sales - measured as the difference between the cash proceeds and the cost basis, determined on a first-in, first-out basis - are also reported within this line item.

Previous wording

The Company accounts for income taxes pursuant to ASC 740, Income Taxes (“ASC 740”), 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 ASC 740 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, 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 condensed 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.
