1 Includes BTC earned from profit sharing associated with a hosting agreement that expires in December 2023 at the Lake Mariner facility and TeraWulf’s net share of BTC produced at the Nautilus Cryptomine facility.
2 Values profit share BTC at $28,104 per BTC as opposed to $38,000 per BTC, which was the quoted price of bitcoin in the Company’s principal market at the time of hosting contract inception.
3 Values profit share BTC at $27,913 per BTC as opposed to $38,000 per BTC, which was the quoted price of bitcoin in the Company’s principal market at the time of hosting contract inception.
4 The Company’s share of the earnings or losses of operating results at the Nautilus Cryptomine facility is reflected within “Equity in net income (loss) of investee, net of tax” in the 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 consolidated statements of operations. The Company uses these metrics as indictors 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.
5 Includes BTC earned from profit sharing associated with a hosting agreement that expires in December 2023 at the Lake Mariner facility and TeraWulf’s net share of BTC produced at the Nautilus Cryptomine facility.
6 Computed as the weighted-average opening price of BTC on each respective day the Self-Mined Bitcoin is earned. Excludes value earned from hosting contract, which expires in December 2023, for which the quoted price of bitcoin in the Company’s principal market at the time of contract inception was approximately $38,000.
7 Q3 2023 and Q2 2023 Calculation excludes 13 and 17 bitcoin, respectively, earned via hosting profit share.
8 While nameplate inventory for WULF’s two facilities is 5.5 EH/s, inclusive of gross total hosted miners, 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.Management Commentary
“We continue to execute our stated goals, delivering strong results in Q3 2023,” stated Paul Prager, Chief Executive Officer of TeraWulf. “While the summer months are seasonally the most challenging operating environment, we demonstrated strong operational results due to outstanding effort by our operating employees to optimize the performance of our miners as well as the advantageous location of our facilities in the Northeast U.S., which has temperate conditions, resulting in fewer high heat events and ensuing wear and tear on our machines, relative to regions like Texas with more extreme weather,” added Prager.
“From a growth perspective, during the third quarter, we significantly advanced construction of Building 3 at our Lake Mariner facility, which when completed, will add 43 MW of infrastructure capacity,” commented Nazar Khan, Chief Operating Officer of the Company. “We plan to energize Building 3 with S19j XPs, 5,500 of which will be self-mining, with the balance of miners to be host-to-owned for BITMAIN until we complete payment for the entire 18,500 miner order, which we expect by the fourth quarter of 2024.”
“Converting our prior deposits on the S19j XP order into owned machines not only underscores the value of our strategic relationship with BITMAIN, but also exemplifies our capital-efficient, infrastructure-first approach to managing growth ahead of the next halving in April,” said Prager. “By virtue of the host-to-own arrangement, we will defer additional capital outlays for the S19j XP order until well beyond the halving, and avoid what might be excessive dilution given current depressed market valuations.”
Production and Operations Update
As of September 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 pursuant to an agreement that expires in December 2023) and 16,000 self-miners at the nuclear-powered Nautilus Cryptomine facility in Pennsylvania. The Company’s total installed hashrate was 5.5 exahashes per second (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 bitcoin mining infrastructure capacity from its current 110 MW to 153 MW by year-end 2023. In July 2023, the Company announced the purchase of 18,500 Antminer S19j XP bitcoin mining machines from BITMAIN, which have 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 EH/s for the 18,500 units, which are targeted to be delivered and installed at the Lake Mariner facility in December 2023. The Company announced plans to convert the deposits already made towards the S19j XP purchase order into 5,500 miners and host-to-own the remaining 13,000 miners for BITMAIN with the expectation to complete the entire 18,500 miner purchase by the fourth quarter of 2024.
As of September 30, 2023, the Company’s stake in phase one of the Nautilus Cryptomine 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 the Nautilus Cryptomine facility, for a total of 100 MW, which TeraWulf plans to deploy in future phases pending capital availability.
Third Quarter 2023 GAAP Financial Results
Revenue in the third quarter of 2023 increased 22.6% to $19.0 million as compared to $15.5 million in the second quarter of 2023. This increase is attributable to a significant growth in operating self-mining hashrate as well as a higher average bitcoin price relative to the second 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 within equity in net income (loss) of investee, net of tax in the consolidated statements of operations.
Gross profit in the third quarter increased to $10.7 million compared to $10.3 million in the second quarter of 2023. Gross profit margin as a percentage of revenue decreased to 56.4% in the third quarter of 2023 compared to 66.9% in the second quarter of 2023, primarily driven by energy costs at the Lake Mariner facility as well as an increase in bitcoin network difficulty.

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 table 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):
