Management Commentary
“We continue to execute our stated goals, delivering strong results in Q2 2023. Based on the continued hard work and commitment of our people, we achieved our target of 5.5 EH/s of capacity in the second quarter,” stated Paul Prager, Chief Executive Officer of TeraWulf.
“As we move into the third quarter, we are actively expanding our Lake Mariner facility by 60% with the addition of 43 MW of infrastructure and 18,500 of the latest generation S19j XPs. This near term expansion will further establish TeraWulf as one of the most efficient mining fleets in the sector with a realized average cost of power of 3.5 cents per kilowatt hour and average availability in excess of 98%,” added Prager. “We continue to reiterate that not all exahash is created equal. With this expansion, we are strategically adding efficient and profitable hashing capacity thereby positioning the Company for increased profit margins ahead of the next halving.”
Production and Operations Update
As of June 30, 2023, the Company had an operational miner fleet of approximately 50,000 of the latest generation miners, comprised of 34,000 miners at its wholly owned Lake Mariner facility in New York (5,000 of which are hosted) and 16,000 self-miners at the nuclear-powered Nautilus facility in Pennsylvania. The Company’s total operational hash rate increased to 5.5 EH/s and 160 MW of capacity across its two sites.
TeraWulf is currently expanding mining operations at its wholly owned Lake Mariner facility in New York with the addition of Building 3, which is expected to increase the facility’s operational capacity from 110 MW currently to 153 MW by year-end 2023. In connection with the expansion, the Company purchased and plans to deploy 18,500 Antminer S19j XP bitcoin mining machines, which are the next generation unit offered by BITMAIN with a power-efficiency rating of 21.5 joules per terahash (J/TH) and a bitcoin mining hashrate of 151 terahash per second (TH/s) each, for a combined total hashrate of 2.8 exahashes per second (EH/s) for the 18,500 units.
As of June 30, 2023, the Company’s stake in phase one of the Nautilus facility – 50 MW and 1.9 EH/s – was fully operational. TeraWulf has the option to add an additional 50 MW of Bitcoin mining capacity at Nautilus, for a total of 100 MW, which TeraWulf plans to deploy in future phases pending capital availability.
With the addition of Building 3 at Lake Mariner, the Company expects to increase its total self-mining hashrate by approximately 58% (from 5.0 EH6 to 7.9 EH/s). The planned expansion with S19j XPs is expected to further establish TeraWulf as one of the most efficient mining fleets in the sector with a fleet efficiency of 25.7 J/TH.
Second Quarter 2023 GAAP Financial Results
Revenue in the second quarter of 2023 increased 34% to $15.5 million compared to $11.5 million in the first quarter of 2023. The increase is attributable to a significant increase in operating self-mining hashrate as well as a higher average price of Bitcoin relative to the first quarter of 2023. Notably, Revenue and expenses reported in the TeraWulf GAAP income statement excludes revenue and expenses from the Nautilus joint-venture; the net financial impact of the Nautilus joint-venture is captured in the “Equity in net less of investee, net of tax” line item
Cost of revenue in the second quarter increased 2% to $5,113 million compared to $5,002 million in the first quarter of 2023. Cost of revenue as a percentage of revenue decreased to 33% in the second quarter of 2023 compared to 43% in the first quarter of 2023 primarily driven by decreased energy costs at Lake Mariner Data.
Cost of Operations in the second quarter of 2023 increased by 3% to $16.2 million compared to $15.8 million in the first quarter of 2023. Although total Operating Expenses and SG&A fell 6% as part of the Company’s cost reduction strategy, $1.0 million of additional depreciation expense offset operational cost reductions.

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 (“GAAP”). The Company’s non-GAAP “Adjusted EBITDA” excludes (i) impacts of interest, taxes, depreciation and amortization; (ii) preferred stock dividends, stock-based compensation expense 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) equity in net loss of investee, net of tax, related to Nautilus; (iv) costs related to non-routine regulatory activities, which costs management does not believe are reflective of the Company’s ongoing operating activities; (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; and (vi) gains and losses related to discontinued operations that are not be applicable to the Company’s future business activities. The Company’s non-GAAP 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 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 that excludes these items 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 GAAP and should not be considered as an alternative to operating (loss) income or any other measure of performance derived in accordance with 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 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 GAAP.
The following is a reconciliation of the Company’s non-GAAP adjusted EBITDA to its most directly comparable GAAP measure (i.e., net loss attributable to common stockholders) for the periods indicated (in thousands):
