THE POWER OF INFRASTRUCTURE Q3 2026 INVESTOR UPDATE Q3 2026 BUSINESS UPDATE NOVEMBER 6, 2026


 
SAFE HARBOR STATEMENT SAFE HARBOR This presentation is for informational purposes only and contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, as amended. Such forward-looking statements include statements concerning anticipated future events and expectations that are not historical facts. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements. In addition, forward-looking statements are typically identified by words such as “plan,” “believe,” “goal,” “target,” “aim,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “seek,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “strategy,” “opportunity,” “predict,” “should,” “would” and other similar words and expressions, although the absence of these words or expressions does not mean that a statement is not forward- looking. Forward-looking statements are based on the current expectations and beliefs of TeraWulf’s management and are inherently subject to a number of factors, risks, uncertainties and assumptions and their potential effects. There can be no assurance that future developments will be those that have been anticipated. Actual results may vary materially from those expressed or implied by forward-looking statements based on a number of factors, risks, uncertainties and assumptions, including, among others: (1) TeraWulf’s ability to a ract additional customers to lease its HPC data centers; (2) TeraWulf’s ability to complete its data center campuses and future strategic growth initiatives in a timely manner or within anticipated cost estimates; (3) operational risks associated with its data centers and TeraWulf’s ability to perform under its existing data center lease agreements; (4) failure to obtain adequate financing on a timely basis and/or on acceptable terms with regard to expansion or existing operations; (5) changes in applicable laws, regulations and/or permits affecting TeraWulf’s operations or the industries in which it operates; (6) adverse geopolitical or economic conditions, including a high inflationary environment, the implementation of new tariffs and more restrictive trade regulations; (7) the potential of cybercrime, money-laundering, malware infections and phishing and/or loss and interference as a result of equipment malfunction or break-down, physical disaster, data security breach, computer malfunction or sabotage (and the costs associated with any of the foregoing); (8) the availability and cost of power as well as electrical infrastructure equipment necessary to maintain and grow our business and operations; and (9) other risks and uncertainties detailed from time to time in the Company’s filings with the Securities and Exchange Commission (“SEC”). Potential investors, stockholders and other readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they were made. TeraWulf does not assume any obligation to publicly update any forward-looking statement after it was made, whether as a result of new information, future events or otherwise, except as required by law or regulation. Investors are referred to the full discussion of risks and uncertainties associated with forward-looking statements and the discussion of risk factors contained in the Company’s filings with the SEC, which are available at www.sec.gov. This presentation contains references to certain non-GAAP financial measures, including “Adjusted EBITDA,“ “net debt” and "non-GAAP Segment Margin". For definitions of these terms and a detailed reconciliation between the non- GAAP financial results presented in this presentation and the corresponding GAAP measures, please refer to the Footnotes and Appendix in this presentation. In addition, this presentation includes a forward-looking non-GAAP financial measure, “net operating income” (“NOI”), which the Company defines as lease revenue for a specific lease less cost of revenue. Cost of revenue includes labor, insurance, property taxes, security, IT equipment , software and labor, and other costs directly related to the lease. Management uses NOI to assess the projected operating performance of individual leases. The most directly comparable GAAP measure is segment gross profit or loss. NOI has significant limitations as an analytical tool and should not be considered in isolation or as a substitute for GAAP results. In evaluating NOI, you should be aware that future non-reimbursable lease operating expenses may arise that are not currently known. The Company’s presentation of NOI should not be construed as an inference that its future results will be unaffected by unusual or non-recurring items. This measure excludes the impact of capital expenditures, material financial obligations, general and administrative expenses and depreciation and amortization, all of which have real economic effects and could materially affect the Company’s consolidated financial results. Definitions and calculations of NOI may vary among companies, and therefore the Company’s NOI may not be comparable to similar measures published by others. A reconciliation of NOI to segment gross profit or loss is not provided because NOI is only calculated for specific leases. Certain amounts cannot be reasonably estimated without unreasonable efforts because certain reconciling metrics are out of the Company’s control, and such estimates would imply a degree of precision that could be misleading to investors. 2

ADJUSTED EBITDA Note: All values in thousands. 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 management uses Adjusted EBITDA to eliminate the effects of certain non-cash and/or non-recurring items that it believes does not reflect the Company's ongoing strategic business operations. Adjusted EBITDA is provided in addition to, and not as a substitute for, or as superior to, the comparable GAAP measure, net income (loss). The Company defines non-GAAP “Adjusted EBITDA” as net income (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 se led 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 and the gain on sale of equity interest in investee; (iv) interest income and other (loss) income, net 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.
