The Company commenced earning revenues in July with its delivery of WULF Den and expects delivery of and revenue generation for CB-1 this month and CB-2 in the fourth quarter, as previously guided. At the same time, we are in advanced discussions to expand HPC hosting deployments at Lake Mariner and are actively pursuing additional sites to support our long-term growth pipeline.” Prager continued, “We continue to see strong demand from enterprise and hyperscale customers for low-cost, zero-carbon compute infrastructure. At Lake Mariner, we have secured interconnection approval to draw 500 MW from the grid, with additional approvals pending to reach up to 750 MW. Our ability to scale quickly provides a meaningful advantage in today’s race to secure power and compute capacity. We remain laser-focused on expanding our platform to meet customer demand and building a high-value business with long-term, durable cash flow.” Patrick Fleury, Chief Financial Officer, added, “We will begin recognizing revenue from HPC hosting in the third quarter of 2025, marking a key inflection point in our financial profile. With our previously announced financing strategies underway and a disciplined approach to capital allocation, we are confident in our ability to scale responsibly while driving meaningful value for shareholders.” Second Quarter 2025 GAAP Financial Results Revenue for the second quarter increased 34% year-over-year to $47.6 million, reflecting a higher average bitcoin price and expanded mining capacity partially offset by anticipated headwinds from the April 2024 halving and increased network difficulty. Cost of revenue, exclusive of depreciation, increased 59% year-over-year to $22.1 million, driven by greater infrastructure utilization and slightly higher power costs in Upstate New York. Liquidity and Capital Resources As of June 30, 2025, the Company held $90.0 million in cash and cash equivalents and bitcoin. Total outstanding debt was approximately $500.0 million, consisting of the Company's 2.75% convertible senior notes due 2030. As of August 6, 2025, TeraWulf had 391,926,373 shares of common stock outstanding.

Non-GAAP Measures We have not provided reconciliations of preliminary and projected Adjusted EBITDA to the most comparable GAAP measure of net income/(loss). Providing net income/(loss) is potentially misleading and not practical given the difficulty of projecting event-driven transactional and other non-core operating items that are included in net income/(loss), including but not limited to asset impairments and income tax valuation adjustments. Reconciliations of this non-GAAP measure with the most comparable GAAP measure for historical periods is indicative of the reconciliations that will be prepared upon completion of the periods covered by the non-GAAP guidance. Please reference the “Non-GAAP financial information” accompanying our quarterly earnings conference call presentations on our website at www.terawulf.com/investors for our GAAP results and the reconciliations of these measures, where used, to the comparable GAAP measures.

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, related party expense settled with respect to Common Stock, 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 income of investee, net of tax, related to Nautilus; (iv) interest income which management believes is not reflective of the Company’s ongoing operating activities; (v) acquisition-related transaction costs which management believes is not reflective of the Company’s ongoing operating activities; and (vi) loss on extinguishment of debt and loss on disposals of property, plant and equipment, which are not reflective of the Company’s general business performance. The Company’s Adjusted EBITDA also included 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 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): Three Months Ended June 30, Six Months Ended June 30, 2025 2024 2025 2024 Net loss$(18,370) $(10,876) $(79,788) $(20,489)Adjustments to reconcile net loss to non-GAAP Adjusted EBITDA: Equity in net income of investee, net of tax — (767) — (6,042)Distributions from investee, related to Nautilus — 7,065 — 19,087 Income tax benefit — — — — Interest income (1,232) (447) (3,491) (947)Loss on disposals of property, plant, and equipment 3,831 — 3,831 — Loss on extinguishment of debt — — — 2,027 Change in fair value of contingent consideration 1,600 — 1,600 — Interest expense 4,012 5,325 8,061 16,370 Depreciation 18,786 14,133 34,360 29,221 Amortization of right-of-use asset 750 251 1,435 503 Stock-based compensation expense 1,304 4,842 39,978 11,773 Related party expense settled with respect to common stock 2,375 — 2,375 — Acquisition-related transaction costs 1,475 — 1,475 — Non-GAAP Adjusted EBITDA$14,531 $19,526 $9,836 $51,503 1 Excludes bitcoin earned from profit sharing associated with a hosting agreement that expired in February 2024 at the Lake Mariner Facility and includes TeraWulf's net share of bitcoin produced at the Nautilus Cryptomine Facility in Q2 2024.2 The Company's share of the earnings or losses of operating results at the Nautilus Cryptomine Facility in Q2 2024 is reflected within "Equity in net income (loss) of investee, net of tax" in the condensed consolidated statements of operations. Accordingly, operating results of the Nautilus Cryptomine Facility are not reflected in revenue, cost of revenue or cost of operations lines in TeraWulf's condensed consolidated statements of operations. The Company uses these 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. All figures except Bitcoin Self-Mined are estimates.3 Excludes bitcoin earned from profit sharing associated with a bitcoin miner hosting agreement that expired in February 2024 at the Lake Mariner Facility and includes TeraWulf’s net share of bitcoin mined at the Nautilus Cryptomine Facility, based on the hashrate share attributed to the Company.4 Computed as the weighted-average opening price of bitcoin on each respective day the self-mined bitcoin is earned.5 While nameplate at the Lake Mariner Facility was 12.8 EH/s as of June 30, 2025 and was 8.8 EH/s for TeraWulf’s two facilities as of June 30, 2024, 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.
