ITEM 1. Business
Overview
We are a vertically integrated owner, developer, and operator of large-scale digital infrastructure in the United States, purpose-built to support high-performance computing (“HPC”) workloads, including artificial intelligence (“AI”), machine learning, and advanced cloud applications.
Our strategy is grounded in controlling infrastructure at utility scale and pairing compute‑optimized facilities with reliable, long‑duration power resources. By controlling land use through ownership or long-term ground leases, together with interconnection rights, electrical and cooling infrastructure, and, where applicable, on-site generation, we deliver resilient, cost-efficient capacity to hyperscale and enterprise customers through long-term hosting arrangements. This infrastructure-first approach enables TeraWulf to serve Tier-1 counterparties while maintaining operational control, development flexibility, and disciplined capital allocation.
Our platform is differentiated by long-term control of utility-scale infrastructure, deep in-house power and grid expertise, and a scalable development model supported by long-term, credit-enhanced customer contracts.
HPC Platform and Development Pipeline
Our contracted HPC platform currently consists of two primary campuses:
•Lake Mariner Data Campus (the “Lake Mariner Data Campus”), located in Barker, New York within the single-state New York Independent System Operator (“NYISO”) market; and
•Abernathy HPC Campus (the “Abernathy HPC Campus”), located in Abernathy, Texas, within the Southwest Power Pool (SPP).
Both campuses have been engineered for phased, large‑scale deployments of liquid‑cooled, hyperscale compute and are supported by long‑term contractual arrangements with credit‑enhanced counterparties. Together, these campuses have contracted 522 MW of critical IT load with long‑dated revenue visibility.
In addition, the Company holds a long‑term ground lease in Lansing, New York (the “Cayuga Site”), which, upon completion of permitting and site development, has the potential to support up to 400 MW of gross capacity, representing approximately 320 MW of contractual critical IT load. The Cayuga Site provides a third anchor location with existing interconnection and supporting infrastructure and represents a key component of the Company’s forward development pipeline.
Through a combination of contracted capacity and future expansion opportunities, TeraWulf has established a multi‑regional HPC platform designed to support sustained growth. The Company’s development model targets the contraction of approximately 250 MW to 500 MW of new critical IT HPC capacity annually, aligned with customer demand, power availability, and regional grid conditions.
Business Strategy
TeraWulf’s business strategy is focused on the development, ownership, and operation of large‑scale, power‑advantaged digital infrastructure serving hyperscale and enterprise HPC workloads. Our approach is differentiated by:
•Infrastructure Control and Vertical Integration – We retain majority ownership and direct operational control over core infrastructure assets, including land positions (through ownership or long‑term ground leases), interconnection rights, electrical systems, cooling infrastructure, and, where applicable, on‑site generation. This vertical integration enables disciplined execution, governance oversight, and infrastructure‑style returns.
1
•Long‑Term, Credit‑Enhanced Contracting – Our HPC arrangements are structured as long‑term data center leases, typically with base terms ranging from 10 to 25 years, contractual escalators, and renewal and contraction options. Certain projects benefit from investment‑grade credit support, materially strengthening the risk profile and durability of contracted revenues.
•Scalable, Multi‑Phase Development – Each campus is designed for modular expansion. Initial phases deliver near‑term contracted capacity, while subsequent phases are developed in line with customer deployment schedules and power availability. This phased approach allows us to efficiently convert advantaged infrastructure positions into incremental contracted capacity over time.
Our strategy is designed to produce durable, infrastructure‑like cash flows while preserving flexibility to scale alongside accelerating demand for compute.
Evolution of Our Business and Capital Allocation
TeraWulf has undergone a deliberate strategic transition toward HPC hosting as its primary business. While the Company operates legacy bitcoin mining facilities and leverages this flexible compute load to support early HPC infrastructure development, going forward capital allocation will be focused on HPC data center development, long-term hosting arrangements, and infrastructure supporting AI-driven compute workloads.
While the Company currently derives the majority of its revenue from bitcoin mining, HPC hosting is now the Company’s primary growth driver and operating focus.
Power Strategy and Responsible Design
TeraWulf’s power strategy emphasizes reliability, efficiency, and responsible integration with regional electric grids. Our campuses are designed to operate with long-duration, cost-competitive power resources that support both customer uptime requirements and broader grid stability.
The Company’s development and operations team brings deep experience in power generation, transmission, interconnection, and large-scale energy infrastructure, which informs site selection, facility design, and day-to-day operations. This expertise enables TeraWulf to evaluate and develop complex, power-intensive sites efficiently and to structure infrastructure solutions that support high-density, mission-critical compute. We believe this power and infrastructure experience provides meaningful differentiation relative to many data center developers that do not have comparable in-house energy expertise.
As part of this strategy, the Company expects to acquire and develop sites that may include on-site generation, battery storage, and other dispatchable resources, primarily to enhance reliability for mission-critical compute and to support grid operations where appropriate. These assets are intended to improve operational resilience, enable participation in ancillary services, and reduce congestion and volatility on regional power systems. Rather than relying on a singular energy narrative, TeraWulf focuses on responsible facility design, efficient power utilization, and long-term infrastructure stewardship.
Environmental and Power Considerations
TeraWulf’s approach to environmental and energy considerations is grounded in responsible infrastructure design, operational efficiency, and reliable integration with regional electric grids. The Company develops and operates digital infrastructure on existing industrial and energy sites, prioritizing reuse of legacy assets and minimizing incremental land disturbance.
Our data center campuses are engineered to support high-density, mission-critical compute while emphasizing efficient power utilization, advanced cooling architectures, and resilient electrical design. These facilities are designed to operate with a range of long-duration power resources, including grid-supplied electricity and, where appropriate, on-site generation.
The Company’s environmental focus is centered on disciplined development, efficient operations, and long-term infrastructure stewardship rather than reliance on any single energy source or environmental attribute.

Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the consolidated financial statements. Unless the context otherwise requires, references in this Quarterly Report on Form 10-Q to the “Company,” “TeraWulf,” “we,” “us” or “our” refer to TeraWulf Inc. and its consolidated subsidiaries, unless otherwise indicated. Certain statements contained in this Management’s Discussion and Analysis of Financial Condition and Results of Operations may be deemed forward-looking statements. See “Forward-Looking Statements.”
Overview
We are a vertically integrated owner, developer, and operator of digital infrastructure assets in the United States, purpose-built to support HPC workloads, including AI, machine learning, and advanced cloud applications.
During the three and six months ended June 30, 2026, HPC leasing revenue represented a majority of total revenue, reflecting the continued ramp of long-term contracted capacity at the Lake Mariner Data Campus.
The Company has undergone a deliberate strategic transition toward HPC leasing as its primary growth driver and operating focus. While TeraWulf historically operated bitcoin mining facilities and used flexible compute loads to support the development of its infrastructure platform, the Company has begun to curtail and repurpose portions of that infrastructure to support HPC development. Going forward, the Company’s capital allocation, development activities and operating focus are centered on HPC data center development, long-term data center leases and infrastructure supporting AI-driven compute workloads. The Company intends to continue bitcoin mining operations where they remain economically attractive and do not conflict with HPC development.
Our strategy is grounded in controlling utility-scale infrastructure and pairing compute-optimized facilities with reliable, long-duration power resources. Through ownership or long-term control of land, interconnection rights and electrical and cooling infrastructure - and, where appropriate, on-site generation - the Company seeks to deliver resilient, cost-efficient capacity to hyperscale and enterprise customers under long-term data center leases. These arrangements generally range from 10 to 25 years and, in certain cases, benefit from investment-grade credit support, enhancing the durability and bankability of contracted revenues. The Company expects these arrangements to provide long-term revenue visibility and support project-level financing as the platform scales.
The Company’s platform is differentiated by its control of utility-scale infrastructure, deep in-house power and grid expertise, and a scalable development model supported by long-term, credit-enhanced customer contracts.
Strategy Execution and Capital Allocation
Management’s execution of the Company’s strategy is focused on converting advantaged infrastructure positions into long-term, contracted HPC capacity. This includes the phased conversion of existing infrastructure, where appropriate, and the development of new campuses aligned with customer deployment schedules and power availability. This execution model emphasizes vertical integration, long-duration customer contracts supported by credit enhancement and disciplined, phased development.
A core element of this approach is infrastructure control. By retaining control over land use, interconnection rights and electrical and cooling systems—and on-site generation where appropriate—the Company is able to manage development risk, optimize capital deployment and maintain operational oversight throughout the lifecycle of its facilities. Management believes this approach reduces execution risk relative to development models that rely more extensively on third parties.
The Company’s contracting strategy prioritizes long-term data center leases with credit-supported customers. These arrangements reduce the Company’s exposure to commodity-driven revenue streams, including bitcoin price volatility, as its revenue mix continues to shift toward contracted HPC leasing. They also provide long-term revenue visibility, support project-level financing and reduce cash-flow volatility as the platform scales. Credit enhancement associated with certain customer contracts has been an important factor in accelerating development timelines and facilitating third-party financing.
53
Each campus is designed for modular, multi-phase expansion. Initial phases are intended to deliver near-term contracted capacity, while subsequent phases are aligned with customer deployment schedules and infrastructure readiness, including power availability and interconnection timing. Management believes this phased approach allows the Company to scale efficiently while maintaining capital discipline.
While the Company currently derives a significant portion of its revenue from bitcoin mining, HPC leasing is now the Company’s primary growth driver and operating focus.

Muskie Data Campus
In May 2026, the Company acquired 100% of the membership interests of Industrial Equity Partners LLC, which owned or held contractual rights to purchase approximately 308 acres of land in Grayson, Kentucky (the "Muskie Data Campus"). The Muskie Data Campus is a hyperscale HPC/AI development site.
Transmission infrastructure and energy service agreements for the Muskie Data Campus were executed concurrently with the Membership Interest Purchase Agreement pursuant to the applicable Industrial General Service tariff structure for large loads, establishing a clear pathway to long-term, large-scale power delivery. The energy services agreement with Kentucky Power Company, an AEP Company, provides for 1,000 MW of contracted electric service. Energy service is expected to commence in the fourth quarter of 2028.
Kentucky Power Company is also constructing a 345 kV substation connected to the existing 765 kV transmission network, providing redundant, utility-scale power infrastructure designed to support the full 1,000 MW Muskie Data Campus. Along with the Company's 480 MW Justified Data Campus, the Muskie Data Campus represents the Company’s second major digital infrastructure campus in Kentucky. This further expands the Company’s presence in a state that continues to emerge as an attractive market for large-scale AI and HPC development due to its robust energy infrastructure, supportive business environment, and strong engagement from state and local stakeholders.
Operations Overview
Lake Mariner Data Campus
The Lake Mariner Data Campus is TeraWulf’s flagship HPC campus and a core component of the Company’s contracted HPC platform. The Lake Mariner Data Campus is located in Barker, New York on the site of a former coal-fired power plant that was retired and repurposed into a modern digital infrastructure campus with operations that commenced in March 2022. The site benefits from substantial existing transmission infrastructure and is designed for scalable expansion.

The campus is undergoing phased expansion to support additional HPC contracted deployments with gross capacity of approximately 500 MW in the near term, and with potential expansion to approximately 750 MW, subject to additional approvals from the NYISO. During the six months ended June 30, 2026, certain mining facilities were curtailed or repurposed to support HPC development, consistent with the Company’s strategic transition. In July 2026, TeraWulf had energized 102 MW of critical IT HPC leasing capacity at the Lake Mariner Data Campus.
The Lake Mariner Data Campus sources power from the NYISO Zone A grid, which is characterized by low-cost, low-carbon energy. Of the campus’s total power needs, 90 MW is allocated under an agreement with the New York Power Authority (“NYPA”) executed in February 2022, providing high-load factor power under a ten-year term commencing with NYPA’s initial power delivery.
The Lake Mariner Data Campus is designed to support multiple hyperscale and enterprise tenants through modular, phased development and incorporates advanced liquid-cooling systems, redundant electrical architectures, and scalable mechanical and network infrastructure optimized for high-density GPU deployments.
TeraWulf operates the Lake Mariner Data Campus through its subsidiaries La Lupa Data LLC (“La Lupa”) and Akela Data LLC (“Akela”). Collectively, La Lupa and Akela represent 438 MW of contracted critical IT HPC capacity at the Lake Mariner Data Campus, with some deliveries having commenced in 2025 and during the six months ended June 30, 2026, and others extending into the second half of 2026 and early 2027.
La Lupa
In December 2024, La Lupa entered into long-term data center lease agreements with Core42 (the “Core42 Leases”), pursuant to which we committed to deliver 60 MW of critical IT load. The Core42 Leases have an initial ten-year term with two five-year renewal options and include customary provisions governing operating standards, service levels, and expansion rights. Construction commenced in 2024 and continued into 2025 and 2026; commissioning activities commenced in 2025 with phased deliveries aligned to meet Core42’s deployment schedule. Operationally, we continue to execute on our buildout. As of June 30, 2026, we had fully delivered CB-2, representing the full contracted capacity under the Core42 Leases currently in service.
55
Akela
In August 2025, Akela entered into three data center lease agreements (the “Akela Fluidstack Leases”) with Fluidstack USA I Inc. (together with its affiliates, “Fluidstack”), a leading AI cloud platform. Under the Akela Fluidstack Leases, we will provide 378 MW of critical IT load at the Lake Mariner Data Campus, which represents the majority of the remaining contracted HPC capacity at the Lake Mariner Data Campus. As of June 30, 2026, one of the Akela Fluidstack Leases had partially commenced and the remaining leases are expected to commence in the second half of 2026 and in early 2027.
The Akela Fluidstack Leases benefit from substantial credit support provided by Google, which supports Fluidstack’s payment and performance obligations under the leases and materially enhances the credit quality and bankability of our contracted lease revenues. This credit support was a key factor in enabling efficient financing and phased development of the Akela facilities.

(the “Fluidstack Member”) to govern the terms of operation of FS CS 1 LLC (the “Abernathy Joint Venture”), which will develop, lease and operate the Abernathy HPC Campus.
On July 6, 2026, the Company entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with the Fluidstack Member and certain other purchasers (collectively, the “Purchasers”) selling to the Purchasers all of the Company’s 50.1% membership interest in the Abernathy Joint Venture for aggregate cash consideration of approximately $530.0 million. As a result of this transaction, the Company no longer holds an equity interest in the Abernathy Joint Venture.
Regional Diversification and Platform Resilience
The development of the Justified Data Campus and the Muskie Data Campus provides the Company with meaningful regional diversification. By expanding its HPC platform beyond New York into the regions operated by the Mid-continent Independent System Operator (“MISO”) and PJM Interconnection, L.L.C. (“PJM”), the Company reduces its concentration in any single power market, regulatory framework or geographic area.
Geographic diversification also reduces the Company’s exposure to localized weather events, construction delays and operational disruptions. Management believes this diversification enhances overall platform resilience, supports customer deployment flexibility and strengthens the Company’s ability to maintain continuity of operations across its portfolio.
Power Strategy
The Company’s power strategy emphasizes reliability, efficiency, and responsible integration with regional electric grids. The Company’s campuses are designed to operate with long-duration, cost-competitive power resources that support both customer uptime requirements and broader grid stability.
The Company’s development and operations team brings deep experience in power generation, transmission, interconnection, and large-scale energy infrastructure, which informs site selection, facility design, and day-to-day operations. This expertise enables the Company to evaluate and develop complex, power-intensive sites efficiently and to structure infrastructure solutions that support high-density, mission-critical compute. The Company believes this power and infrastructure experience provides meaningful differentiation relative to many data center developers that do not have comparable in-house energy expertise.
As part of this strategy, the Company expects to acquire and develop sites that may include on-site generation, battery storage, and other dispatchable resources, primarily to enhance reliability for mission-critical compute and to support grid operations where appropriate. These assets are intended to improve operational resilience, enable participation in ancillary services, and and support stable, long-duration power supply for compute workloads. Rather than relying on a singular energy narrative, the Company focuses on responsible facility design, efficient power utilization, and long-term infrastructure stewardship.
56
Liquidity and Capital Resources
The Company’s primary sources of liquidity include cash on hand, cash generated from operations, sale proceeds from bitcoin, equity issuances, debt financing, and project-level financing arrangements.

Capital requirements are driven primarily by HPC data center development, including significant capital expenditures associated with site development, electrical and mechanical infrastructure, and customer-specific fit-out.
Management expects future capital deployment to prioritize contracted HPC projects and disciplined expansion of the Company’s development pipeline. The Company continues to evaluate debt, equity and project-level financing alternatives based on project requirements, customer commitments and prevailing market conditions, while seeking to manage balance-sheet risk.
Outlook
The Company expects future results to be increasingly influenced by the development and operation of its HPC data center platform. As contracted HPC capacity is delivered and energized and legacy bitcoin mining infrastructure is further curtailed or repurposed, the Company expects its revenue mix to continue shifting toward HPC leasing.
Future performance will depend on the timing of construction, commissioning, customer deployment schedules, access to power and interconnection, and the availability of project-level financing. Management expects capital deployment in future periods to be focused primarily on contracted HPC projects and disciplined expansion of the Company’s development pipeline.

57
As of June 30, 2026, our fleet of miners ranged in age from 1.0 year to 4.1 years with an average age of approximately 1.8 years. We do not have scheduled downtime for our miners and 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. As of June 30, 2026, our fleet of miners at the LMD Bitcoin Mining Facilities had a range of energy efficiency from 15.0 to 23.0 joules per terahash (“j/th”) and has an average energy efficiency of 17.6 j/th.
Bitcoin Mining - Share of Global Hashrate
Several factors influence our ability to mine bitcoin profitably, including bitcoin’s USD value, mining difficulty, global hashrate, power costs, fleet energy efficiency, and overall data center efficiency. Among these, energy efficiency is a critical driver of profitability, as power costs represent the most significant direct expense in bitcoin mining. We believe we operate a highly efficient mining fleet, optimized to maximize output while minimizing energy consumption. To assess operational performance and effectiveness, the Company tracks key metrics, which we believe are also valuable to investors for evaluating our progress and benchmarking against industry peers.
The table below presents our miner efficiency and computing power as compared to the global computing power as of June 30, 2026 and 2025:
| Combined facilities | June 30, 2026 | June 30, 2025 | ||||||||
Global hashrate (EH/s)(1) | 992.0 | 843.0 | ||||||||
Miner efficiency (j/th)(2) | 16.4 | 17.7 | ||||||||
TeraWulf operational hashrate (EH/s)(3) | 5.6 | 12.2 | ||||||||
| TeraWulf percentage of global hashrate | 0.6 | % | 1.4 | % | ||||||
(1) Total global hashrate obtained from YCHARTS (https://ycharts.com/indicators/bitcoin_network_hash_rate).
(2) Joules of energy required to produce each terahash of processing power
(3) While nameplate at the LMD Bitcoin Mining Facilities was 10.6 EH/s and 12.8 EH/s as of June 30, 2026 and 2025, respectively, actual operational hashrate 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 June 30, 2026, our operational hashrate represented approximately 0.6% of the total global hashrate, aligning with our share of global blockchain rewards. As of that date, this translated to approximately 1 bitcoin mined per day. To maintain profitably, we focus on optimizing operational efficiency and cost management, ensuring that our mining rewards consistently cover direct operating expenses.

(1) “Cost to mine one bitcoin” is a cash cost metric and does not include depreciation. Although the Company recognizes depreciation with respect to its mining assets, it does not consider depreciation in determining whether it is economical to operate its mining equipment. As a result, the Company does not consider the sunk costs or depreciation of past capital investments in its historical or forecasted breakeven analysis. If depreciation of our miner fleet were factored into the above cost of mining analysis, it would add $52,939 and $68,305 for the three and six months ended June 30, 2026, respectively. bringing the total “cost to mine one bitcoin” to $97,486 and $91,101 for the three and six months ended June 30, 2026, respectively. If depreciation of our miner fleet were factored into the above cost of mining analysis, it would add $33,745 and $35,294 for the three and six months ended June 30, 2025, bringing the total “cost to mine one bitcoin” to $79,353 and $89,788 for the three and six months ended June 30, 2025, respectively.
(2) Computed as the weighted-average opening price of bitcoin on each respective day the mined bitcoin is earned.
Power costs are the most significant expense in our bitcoin mining operations. During the three and six months ended June 30, 2026, the Company incurred gross power costs of $11.2 million and $25.2 million, respectively. In addition, during the three and six months ended June 30, 2026 and 2025, the Company curtailed operations at the LMD Bitcoin Mining Facilities in response to weather events, energy price spikes, and participation in demand response programs. The Company records expected payments to be received for demand response programs as a reduction in cost of revenue, which amounted to $2.8 million and $16.9 million for the three and six months ended June 30, 2026, respectively, and $3.1 million and $5.9 million for the three and six months ended June 30, 2025. During the six months ended June 30, 2026, there were significant curtailment periods for the Company’s bitcoin mining operations due to sustained low temperatures throughout the Northeastern United States which led to significantly reduced power consumption and significantly higher demand response proceeds for the Lake Mariner Data facility resulting in a lower than typical cost of power for the period.
Energy prices are highly volatile, influenced by global events that can drive nationwide fluctuations in power costs. At the LMD Bitcoin Mining Facilities, 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 and polar vortices, 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
59
LMD Bitcoin Mining Facilities were $0.049 and $0.024 per kilowatt hour during the three and six months ended June 30, 2026, respectively, and $0.053 and $0.065 the three and six months ended June 30, 2025.
Our management team continuously monitors market conditions to determine when and for how long to curtail operations. If curtailment is not mandated under demand response programs, we make real-time decisions to curtail mining whenever power prices exceed the value of the fixed bitcoin reward. As a result, curtailment increases when bitcoin’s value declines or energy prices rise, and decreases when bitcoin’s value appreciates or energy costs fall. These decisions are actively managed on an hour-by-hour basis to optimize profitability.
The Company has purchased all miners with cash, without relying on limited recourse equipment financing for miner acquisitions. To support operations and purchase miners and other fixed assets, we have raised capital through both equity issuances and corporate-level debt. Costs related to these capital raises are not included in this analysis.
Miner acquisition costs, or capital expenditures, are not factored into the cost of mining analysis, as they do not impact the marginal cost of producing one bitcoin. Instead, these costs are recorded as property, plant, and equipment in the condensed consolidated balance sheets. Depreciation of property, plant, and equipment is calculated using the straight-line method, with estimated useful lives of four years for miners and five years for computer equipment.
During the three and six months ended June 30, 2026, the Company recorded accelerated depreciation expense of $2.6 million and $14.5 million, respectively, related to a certain miner building and related miners of which the Company shortened their useful lives based on expected shutdown of operations for purposes of supporting the HPC operations. The Company did not recorded accelerated depreciation expense during the three and six months ended June 30, 2025. While our standard depreciation period for miners is four years, historically low power costs may allow for a longer actual useful life in certain cases. However, if depreciation were included in the cost of mining analysis, it would add $52,939 and $68,305 for the three and six months ended June 30, 2026, respectively. and $33,745 and $35,294 for the three and six months ended June 30, 2025, respectively.
Estimating asset useful lives requires management judgment, particularly given the rapid evolution of next-generation mining rigs in industrial-scale bitcoin mining. Depreciation schedules may be adjusted if events, regulatory changes, or shifts in operating conditions indicate a need for revision. Management continuously evaluates factors such as future energy market conditions, operating costs, maintenance practices, and capital investment needs to ensure depreciation assumptions remain reasonable. When an asset’s estimated useful life is adjusted—either shortened or extended—depreciation provisions are updated accordingly, which could have a material impact on future financial results.
Recent Developments
In July 2026, the Company amended certain of the Akela Fluidstack Leases to increase the aggregate contracted critical IT load under two leases from 162 MW to 168 MW. The amendments also provide for commencement on a data hall-by-data hall basis, with the affected leases expected to commence in phases during the second half of 2026 and early 2027. In connection with certain tenant-requested scope changes, the Company will receive additional base rent per kilowatt of tenant critical power beginning on the applicable data hall commencement date, subject to annual escalation.
In July 2026, the Company entered into a long-term datacenter lease agreement with Anthropic PBC (the “Anthropic HPC Lease”) for specified datacenter infrastructure at the Justified Data Campus to support Anthropic’s HPC operations. Under the Anthropic HPC Lease, the Company will provide approximately 401 MW of critical IT load. The Anthropic HPC Lease has an initial term of 20 years commencing upon delivery of the applicable leased premises and includes two five-year extension options exercisable by Anthropic. Delivery is expected to occur in phases, with initial capacity expected in the second half of 2027 and full delivery expected in early 2028.
In July 2026, the Company entered into a purchase agreement with the Purchasers selling its entire 50.1% membership interest in the Abernathy Joint Venture for aggregate cash consideration of approximately $530.0 million. As a result of this transaction, the Company no longer holds an equity interest in the Abernathy Joint Venture.
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 miners owned by the Company. The earned bitcoin are routinely sold for U.S. dollars.
60
In July 2025, the Company commenced its HPC leasing operations. HPC lease revenue is generated by leasing datacenter space and providing related services to our HPC customers. These leasing agreements include lease components related to the right to use datacenter space and nonlease components for power delivery, physical security, and maintenance services. HPC power costs are passed through to the customer without markup and are included on a gross basis in HPC lease revenue.
The Company’s business strategy centers on maximizing revenue and profitability of our bitcoin mining fleet while expanding our datacenter infrastructure to support HPC leasing activities. We plan to operate infrastructure necessary for profitable bitcoin mining while pursuing high-value HPC leasing opportunities that leverage our power utilization and digital infrastructure. We are confident our expertise in power infrastructure and digital asset mining can be favorably applied to the design, development, and operation of large-scale datacenters. These datacenters are optimized for high-value applications such as cloud computing, machine learning, and artificial intelligence. We are actively seeking opportunities to expand into these areas using our knowledge, expertise, and existing infrastructure wherever favorable market opportunities arise.

Cost of revenue (excluding depreciation) for the three months ended June 30, 2026 and 2025 was $12.4 million and $22.1 million, respectively, representing a decrease of $9.7 million. The decrease was primarily driven by a decrease in gross power costs of $14.5 million related to bitcoin mining operations due to reduced bitcoin mining power consumption as the Company curtailed its mining operations and repurposed two miner buildings to support the expansion of HPC operations at the Lake Mariner Data Campus. This decrease was partially offset by an increase in gross power costs of $4.5 million related to HPC leasing activities and $2.4 million of costs incurred by the Company in connection with its fit-out services under the HPC Leases.
Cost of revenue (excluding depreciation) for the six months ended ended June 30, 2026 and 2025 was $14.8 million and $46.6 million, respectively, representing a decrease of $31.8 million. The decrease was primarily driven by a decrease in gross power costs of $27.7 million related to bitcoin mining operations due to reduced bitcoin mining power consumption as the Company curtailed its mining operations and repurposed two miner buildings to support the expansion of HPC operations at the Lake Mariner Data Campus. This decrease was partially offset by an increase in gross power costs of $3.1 million related to HPC leasing activities and $3.8 million of costs incurred by the Company in connection with its fit-out services under the HPC Leases. In addition, during the six months ended months ended June 30, 2026, the Company significantly curtailed operations at the LMD Bitcoin Mining Facilities due to sustained low temperatures in upstate New York which led to significantly lower gross power costs and significantly higher demand response proceeds resulting in a net negative realized cost of power for the period. Proceeds from participation in demand response programs are recorded as a reduction in cost of revenue in the period in which the underlying program occurs. These proceeds totaled $16.9 million and $5.9 million during the six months ended months ended June 30, 2026 and 2025, respectively. The Company is actively expanding its enrollment in such available programs in New York State.

Depreciation for the six months ended June 30, 2026 and 2025 was $49.7 million and $34.4 million, respectively. The increase was primarily due to mining and HPC infrastructure constructed and placed in service during 2025 at the Lake Mariner Data Campus. Additionally, during the three and six months ended June 30, 2026, the Company recorded accelerated depreciation expense of $2.6 million and $14.5 million related to a certain miner building and related miners of which the Company shortened their useful life based on expected shutdown of operations as well as certain electrical equipment acquired at the Justified Data Campus, each for purposes of supporting the HPC operations.
Loss (gain) on fair value of digital assets, net during the three months ended June 30, 2026 and 2025 was $0.8 million and $(0.9) million, respectively. Loss (gain) on fair value of digital assets, net during the six months ended months ended June 30, 2026 and 2025 was $1.5 million and $(17,000), respectively, due to the volatility and fluctuations in the price of bitcoin during the three and six months ended June 30, 2026 as compared to the same periods in the prior year.
Change in fair value of contingent consideration was $0 during the three and six months ended June 30, 2026, as compared to $1.6 million during the three and six months ended June 30, 2025. The change in the three and six months ended June 30, 2025 related to the fair value remeasurement of contingent consideration liabilities for the acquisition of Beowulf E&D which were fully settled during the year ended December 31, 2025 upon achievement of the related earnout milestones.
Impairment of property, plant, and equipment was $0 and $25.7 million during the three and six months ended June 30, 2026. Impairment of property, plant, and equipment during the six months ended June 30, 2026 was primarily due to $16.8 million impairment charge related to asset retirement costs assumed in connection with the Justified Data Campus

acquisition. The Company assumed an asset retirement obligation as part of the acquisition and recorded the related asset retirement cost in property, plant and equipment, net. Because the related acquired assets were not expected to provide future economic benefit, the capitalized asset retirement cost was fully impaired during the period. The increase was also driven by $8.9 million impairment charges related to the shutdown of a mining facility and the cessation of related bitcoin mining operations to support the Company’s transition to HPC operations.
Loss on disposals of property, plant, and equipment was $0.4 million during the three and six months ended June 30, 2026 due to a $0.2 million loss on the disposal of 360 miners for proceeds of $0.1 million and a $0.3 million write-down of 500 miners reclassified as held for sale, partially offset by a $0.2 million gain on the sale of certain transformers at the Justified Data Campus. 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.
Interest expense during the three months ended June 30, 2026 and 2025 was $56.4 million and $4.0 million, respectively, an increase of $52.4 million. The increase is primarily attributed to increases in stated interest of $43.2 million and increase in amortization of debt issuance costs of $9.1 million related to the 2030 Secured Notes, 2031 Convertible Notes and 2032 Convertible Notes which were issued in 2025.
Interest expense during the six months ended June 30, 2026 and 2025 was $123.5 million and $8.1 million, respectively, an increase of $115.4 million. The increase is primarily attributed to increases in stated interest of $93.6 million and increase in amortization of debt issuance costs of $21.8 million related to the 2030 Secured Notes, 2031 Convertible Notes and 2032 Convertible Notes which were issued in 2025.
Change in fair value of warrants during the three and six months ended June 30, 2026 was $755.7 million and $972.0 million, respectively, related to the Google Warrants driven by the increase in the Company’s stock price.
Loss on extinguishment of debt was $7.1 million during the three and six months ended June 30, 2026 related to the full prepayment of the outstanding $100.0 million principal amount of the Bridge Credit Facility and the termination of the Bridge Credit Agreement. The early repayment resulted in a loss on extinguishment of debt of $7.1 million, representing the write-off of unamortized debt issuance costs.
Interest income during the three months ended June 30, 2026 and 2025 was $29.0 million and $1.2 million, respectively, an increase of $27.8 million. Interest income during the six months ended June 30, 2026 and 2025 was $58.4 million and $3.5 million, respectively, an increase of $54.9 million. These increases were primarily due to higher average cash balances during the period.
Other income was $0.9 million during the three and six months ended June 30, 2026, consisting primarily of proceeds from the sale of scrap metal generated in connection with the Company’s construction activities as well as net unrealized gains on the restricted trust investments.
Income tax provision was $28,000 and $56,000 for the three and six months ended June 30, 2026, respectively. 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 net deferred tax assets as of June 30, 2026 and December 31, 2025, except for a $132,000 and $76,000 deferred tax liability as of June 30, 2026 and December 31, 2025, respectively, arising from indefinite-lived assets (e.g., tax-deductible goodwill related to the acquisition of Beowulf E&D) that cannot be used as a source of taxable income to support the realization of deferred tax assets when a full valuation allowance is in place.
Equity in net loss of investee, net of tax was $11.1 million and $22.6 million for the three and six months ended June 30, 2026, respectively, which represents TeraWulf’s proportional share of net loss of the Abernathy Joint Venture which was formed in October 2025 and has not yet commenced operations.
Non-GAAP Measure
To provide investors with additional information in connection with our results as determined in accordance with generally accepted accounting principals in the United States (“U.S. GAAP”), we disclose Adjusted EBITDA as a non-GAAP measure. This measure is not a financial measure calculated in accordance with U.S. GAAP, and it should not be considered as a substitute for net loss, operating loss, or any other measure calculated in accordance with U.S. GAAP, and may not be comparable to similarly titled measures reported by other companies.

We define Adjusted EBITDA as net loss adjusted for (i) impacts of interest, taxes, depreciation and amortization; (ii) stock-based compensation expense, amortization of right-of-use asset, accretion of asset retirement obligations, related party expenses settled with respect to Common Stock and stock-based charitable contribution to The TeraWulf Charitable Foundation 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 the Abernathy Joint Venture; (iv) interest income and other income for which management believes are not reflective of the Company’s ongoing operating activities; (v) change in fair value of warrant liabilities, changes in fair value of contingent consideration, loss on extinguishment of debt, loss on disposals of property, plant and equipment and impairment of property, plant and equipment which are not reflective of the Company’s general business performance; and (vi) acquisition-related transaction costs which management believes are not reflective of the Company’s ongoing operating activities.
Management believes that providing this non-GAAP financial measure 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 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 provided to certain employees, officers, directors and consultants.
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 U.S. GAAP and should not be considered as an alternative to net loss or any other measure of performance derived in accordance with U.S. 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 U.S. 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 condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP.
