EASTON, Md., May 09, 2025 (GLOBE NEWSWIRE) -- TeraWulf Inc. (Nasdaq: WULF) (“TeraWulf” or the “Company”), which owns and operates vertically integrated, next-generation digital infrastructure primarily powered by zero-carbon energy, today announced its financial results for the first quarter ended March 31, 2025.

First Quarter 2025 GAAP Operational & Financial Highlights

• Revenue was $34.4 million, compared to $42.4 million in Q1 2024.
• Cost of revenue (excluding depreciation) was $24.6 million, compared to $14.4 million in Q1 2024.

• Total value of self-mined bitcoin¹ was $34.4 million, compared to $56.5 million in Q1 2024.
• Power cost per bitcoin was $66,084, compared to $15,501 in Q1 2024, reflecting the halving, rising network difficulty, and short-term power price volatility from the Polar Vortex.
• Adjusted EBITDA was $(4.7) million, compared to $32.0 million in Q1 2024.

Management Commentary

“TeraWulf continues to advance its strategy of developing scalable, sustainable infrastructure for both Bitcoin mining and high-performance computing. As outlined during our fourth quarter 2024 earnings call, our key priorities for 2025 include energizing Miner Building 5 and deploying our upgraded mining fleet, delivering Core42’s contracted 72.5 MW of HPC capacity on schedule, securing financing for our initial HPC data center buildout, and signing additional customers to reach between 200 and 250 megawatts of contracted HPC capacity by the end of 2026,” said Paul Prager, Chief Executive Officer of TeraWulf.

“We’ve made meaningful progress on each of these fronts. In late Q1 and early Q2, we energized Miner Building 5, bringing total capacity at Lake Mariner to 245 MW. We remain on track to deliver the Core42 deployment this year and have initiated the financing process to support our next phase of HPC growth.”

Prager added, “We continue to see robust medium- and long-term demand for high-density, energy-efficient digital infrastructure. In this environment, TeraWulf’s vertically integrated energy platform provides a distinct competitive advantage. We are focused on building a high-value, durable business that is designed to scale with demand and deliver long-term returns.”

Patrick Fleury, Chief Financial Officer, commented, “With $219.6 million in cash and bitcoin holdings at quarter-end, we are well-capitalized to fund our near-term growth. HPC hosting revenue is expected to begin in the second quarter of 2025 as our data halls come online. We also returned $33 million to shareholders during the quarter through share repurchases, reflecting our continued commitment to disciplined capital allocation.”

First Quarter 2025 GAAP Financial Results

Revenue for the first quarter decreased 19% year-over-year to $34.4 million, reflecting anticipated headwinds from the April 2024 halving, increased network difficulty, and elevated power prices, partially offset by a higher average bitcoin price and expanded mining capacity.

Cost of revenue, exclusive of depreciation, increased 70%  year-over-year to $24.6 million, driven by greater infrastructure utilization and temporary increases in power costs due to extreme winter weather in Upstate New York.

Liquidity and Capital Resources

As of March 31, 2025, the Company held $219.6 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 May 7, 2025, TeraWulf had 384,584,010 shares of common stock outstanding.

As part of the Company's regular review of its capital management activities, our Board of Directors recently approved:

• A new $200 million At-the-Market (ATM) common equity offering program, to replace the existing ATM facility.
• A refreshed authorization for a $200 million common stock repurchase program, providing continued flexibility to return capital to shareholders when appropriate.

These programs are intended to preserve flexibility in managing the Company's capital structure and liquidity position.

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.

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 and amortization of right-of-use asset, 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; and (v) loss on extinguishment of debt, which is 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):

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 Q1 2024.

² The Company's share of the earnings or losses of operating results at the Nautilus Cryptomine Facility in Q1 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 inventory for the Lake Mariner Facility was 12.2 EH/s and 8.0 EH/s as of Q1 2025 and Q1 2024, respectively, actual monthly hash rate performance 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. Note the 8.0 EH/s in the table in Q1 2024 is nameplate capacity and average operating hashrate was 6.8 EH/s.
