About this update from Terawulf Inc.

Contracted 522 critical IT MW totaling over $12.8 billion 1 of revenue Secured full funding for contracted capacity with construction advancing in alignment with tenant deployment timelines Multi-year development pipeline enables targeted annual delivery of 250 - 500 critical IT MW through the end of the decade EASTON, Md. , Feb. 26, 2026 (GLOBE NEWSWIRE) -- TeraWulf Inc. (Nasdaq: WULF) (“TeraWulf” or the “Company”), an owner, developer, and operator of energy-advantaged digital infrastructure purpose-built for high-performance computing (“HPC”) and artificial intelligence (“AI”), today announced its financial and operational results for the fourth quarter and full year ended December 31, 2025 . Fiscal year 2025 marked a fundamental inflection point for TeraWulf as the Company executed long-term data center lease agreements totaling 522 critical IT MW, providing multi-year revenue visibility, stable cash-flow characteristics, and scalable development capacity extending through the end of the decade. TeraWulf delivered a transformational fourth quarter, achieving major commercial, operational, and financial milestones that position the Company as a leader in sustainable HPC infrastructure. During the year ended December 31, 2025 , the Company commenced recurring HPC lease revenue, signed more than $12.8 billion 1 in long-term, credit-enhanced customer contracts, and completed $6.5 billion 2 in long-term financings to support its rapidly expanding platform. Strategic and Operational Highlights Contracted, Multi-Regional HPC Platform During 2025, TeraWulf solidified HPC hosting as its primary growth engine while continuing to operate legacy mining infrastructure opportunistically. The Company’s contracted HPC platform includes the flagship Lake Mariner Data Campus in New York (NYISO) and the Abernathy HPC Campus in Texas (SPP), a majority owned joint venture with Fluidstack. Together, these campuses represent 522 critical IT MW under long-term data center lease agreements with credit enhancement. TeraWulf also controls the Cayuga site in New York (NYISO), capable of supporting up to 320 critical IT MW upon permitting and development, extending the Company’s visible growth runway. HPC Leasing Momentum at Lake Mariner Lake Mariner secured long-term lease commitments for: 60 critical IT MW with Core42, commenced in 2025 and commencing in 2026; and 380 critical IT MW with a second tenant, Fluidstack with credit enhancement from Google, commencing in 2026. These agreements materially enhance revenue durability, counterparty credit quality, and financing visibility, establishing Lake Mariner as a hyperscale-ready AI infrastructure campus with long-dated contracted revenue. Geographic Diversification Through the Abernathy Joint Venture In October 2025 , TeraWulf entered into a joint-venture agreement with Fluidstack to develop the Abernathy HPC Campus in Texas , designed to support 168 critical IT MW under a 25-year lease with annual escalators. Construction is progressing with delivery targeted for second half 2026, supported by Google credit enhancement. Capital Formation Supporting Infrastructure Buildout During 2025, TeraWulf completed a comprehensive capital-formation strategy representing more than $6.5 billion 2 of committed capital, aligned with long-term contracted infrastructure delivery and enabling disciplined execution of the Company’s multi-regional development roadmap. Full Year 2025 Financial Results Financial and operational highlights for the fiscal year ended December 31, 2025 include: Revenue of $168.5 million Non-GAAP adjusted EBITDA of $(23.1) million Cash, cash equivalents and restricted cash of $3,722.8 million as of December 31, 2025 Fourth Quarter 2025 Financial Results Digital asset revenue was $26.1 million for the three months ended December 31, 2025 as compared to $43.4 million for the three months ended September 30, 2025 primarily driven by lower bitcoin production and price of bitcoin during the fourth quarter. HPC lease revenue was $9.7 million for the three months ended December 31, 2025 , as compared to $7.2 million for the three months ended September 30, 2025 . Lake Mariner Construction Update Lake Mariner has advanced phased expansion to support hyperscale-class HPC deployments, with 39 critical IT MW HPC capacity online, more than 500 MW of near-term contracted campus capacity, and approximately 250 MW of incremental expansion potential, positioning the campus to support 750 MW of gross HPC leasing capacity. During construction, the Company worked collaboratively with tenants to incorporate additional fit-out enhancements beyond original lease specifications which will optimize the tenants' deployment. Certain building milestones were sequenced accordingly, and associated timing impacts have been incorporated into the Company’s financial plan. Upon full buildout, Lake Mariner is expected to rank among the largest AI and HPC data-center campuses in North America , with low-latency access to nearby population centers exceeding 45 million consumers. Building-Level Construction Status (critical IT MW): WULF Den (2 MW) – Operational CB1 (16 MW) – Operational CB2 (42 MW) – CB2A operational; CB2B expected in March 2026 CB3 (42 MW) – Energization expected mid-May 2026 CB4 (168 MW) – Energization expected Q3 2026 CB5 (168 MW) – Energization expected Q4 2026 Through design optimization across later phases, critical IT capacity for CB4 and CB5 increased from 162 MW to 168 MW per building without increasing base construction budgets, enhancing long-term lease revenue potential. “These projects reflect disciplined construction execution and close coordination with our hyperscale stakeholder and customers,” said Nazar Khan , Chief Technology Officer. “Our teams are advancing build schedules, integrating tenant fit-out requirements, and optimizing cooling, electrical, and design architecture to support next-generation AI workloads at scale.” Multi-Year Development Pipeline and Momentum Into 2026 Subsequent to year-end, TeraWulf expects to expand its infrastructure portfolio through its acquisition of a site in Kentucky (MISO) and its planned acquisition of a site in Maryland (PJM), both strategically located brownfield sites, increasing total platform capacity to approximately 2.9 GW gross across five sites. Collectively, these sites create a multi-year development pathway capable of supporting 250–500 critical IT MW, enabling TeraWulf to scale alongside accelerating AI demand while maintaining disciplined capital deployment, credit-backed contracting, and long-term grid alignment. “We enter 2026 with 522 critical IT MW of contracted HPC capacity and a gross 2.9-GW multi-regional platform designed for long-term expansion,” Prager added. “Our focus remains on disciplined execution, transparent capital allocation, and converting energy-advantaged infrastructure into durable, long-term cash flow.” Investor Conference Call and Webcast TeraWulf will host its fourth-quarter and full-year 2025 earnings call and business update for investors today, Thursday, February 26, 2026 , at 4:30 p.m. ET .

6,957 $ 19,572 Income taxes $ — $ — $ — 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 (“U.S. GAAP”). The Company defines non-GAAP “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 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) one-time, non-recurring transaction-based compensation expense related to the 2030 Convertible Notes (iv) equity in net (loss) income of investee, net of tax, related to the Abernathy Joint Venture and Nautilus and the gain on sale of interest in Nautilus; (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; (vi) change in fair value of contingent consideration, change in fair value of warrant and derivative liabilities, loss on extinguishment of debt and net losses on disposals of property, plant and equipment, net, which are not reflective of the Company’s general business performance; and (vii) acquisition-related transaction costs which management believes are not reflective of the Company’s ongoing operating activities. The Company’s 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) income 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 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 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 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 consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The following table is a reconciliation of the Company’s non-GAAP Adjusted EBITDA to its most directly comparable U.S. GAAP measure (i.e., net loss) for the periods indicated (in thousands): Year Ended December 31 , 2025 2024 Net loss $ (661,416 ) $ (72,418 ) Adjustments to reconcile net loss to non-GAAP Adjusted EBITDA: Gain on sale of equity interest in investee — (22,602 ) Equity in net loss (income) of investee, net of tax 4,130 (3,363 ) Distributions from investee, related to Nautilus — 22,776 Income tax provision 76 — Other income (39,044 ) (3,927 ) Loss on extinguishment of debt — 6,300 Change in fair value of warrants and derivatives 429,793 — Interest expense 80,248 19,794 Loss on disposals of property, plant, and equipment, net 4,895 17,824 Change in fair value of contingent consideration 10,397 — Depreciation 88,597 59,808 Amortization of right-of-use asset 4,456 1,373 Stock-based compensation expense 50,909 30,927 Transaction-based compensation expense — 3,885 Related party expense to be settled with respect to common stock 2,375 — Beowulf E&D acquisition-related transaction costs 1,475 — Non-GAAP adjusted EBITDA $ (23,109 ) $ 60,377 ___________________________1 Includes TeraWulf’s 50.1% net share of revenues contracted at the Abernathy Joint Venture.2 Includes $1.3 billion of Senior Secured Notes issued by a wholly-owned subsidiary of the Abernathy Joint Venture in December 2025 .
