Stronghold Announces Fourth Quarter 2023 Operating and Financial Results

NEW YORK, March 06, 2024 (GLOBE NEWSWIRE) — Stronghold Digital Mining, Inc. (NASDAQ: SDIG) (“Stronghold”, the “Company”, or “we”) today announced financial and operational results for the fourth quarter and full year 2023 and provided an operational update:

Recent Operational and Financial Highlights

• Achieved ~3.8 EH/s of actual hash rate on installed hash rate capacity of 4.1 EH/s, following the installation of 5,000 recently purchased Bitcoin miners. The Company has less than $1mm of outstanding capital commitments for miners heading into the April 2024 halving.
• Current energized slots in existing Stronghold data centers have the capacity to support over 7 EH/s of hash rate. Stronghold believes it has the unique opportunity to significantly increase its hash rate capacity within its existing infrastructure and is evaluating options to accomplish this, including through its existing miner purchase option with Canaan Inc., additional Bitcoin miner replacements, expansion of Bitcoin mining agreements, and other strategic opportunities.
• Executed electricity sales and purchase agreements with Champion Energy Services, LLC, a Calpine company (the “ESPAs”). Stronghold expects the ESPAs to provide a flexible source of power to the Scrubgrass and Panther Creek data centers at a cost that the Company independently estimates will be approximately $10-12/MWh, including all ancillary charges and taxes, plus the cost of wholesale power, assuming prices range from $10-40/MWh. The Company believes that extended periods of low power pricing, especially in shoulder months, will yield the opportunity to import power to reduce overall cost of power.
• Scrubgrass Plant carbon capture project is registered on the Puro Carbon Registry (“Puro”) in late February. The Company expects to begin the audit process with Puro in the near future.
• Second Karbolith™ is now operational at the Scrubgrass Plant.
• Fixed costs down ~$33 million for the full year 2023 versus the full year 2022, representing a ~37% reduction. Fixed costs include operations & maintenance expenses and general & administrative expenses, excluding stock-based compensation.
• The Company generated revenues of $21.7 million, net loss of $21.2 million, and non-GAAP Adjusted EBITDA of $2.3 million during the fourth quarter of 2023. Revenues comprised $15.1 million from cryptocurrency self-mining, $5.4 million from cryptocurrency hosting, and $1.1 million from the sale of energy.¹

Bitcoin Mining Update

Stronghold generated 599 Bitcoin during the fourth quarter of 2023, which was down 3% versus the third quarter of 2023 and represented 34% growth compared to the fourth quarter of 2022, respectively. Bitcoin mining economics began to recover over the course of 2023. Bitcoin hash price, which is Stronghold’s preferred measure of conveying mining revenue per unit of hash rate due to its inclusion of Bitcoin price, transaction fees, and network hash rate/difficulty in the calculation, averaged $81/PH/s during the fourth quarter of 2023 as compared to $62/PH/s during the fourth quarter of 2022, representing a 31% improvement. Bitcoin price averaged $36,247 during the fourth quarter of 2023, up 101% compared to the average of $18,073 during the fourth quarter of 2022. Transaction fees averaged 14.6% of block subsidies during the fourth quarter of 2023, up 620% or 1,255 basis points compared to 2.0% of block subsidies during the fourth quarter of 2022. These improvements were partially offset by the rise in network hash rate, which averaged 460 EH/s during the fourth quarter of 2023, up 81% compared to the average network hash rate of 254 EH/s during the fourth quarter of 2022.

Stronghold mined 170 Bitcoin in February 2024 and generated approximately $0.2 million in energy revenue, which represents the equivalent of approximately 3 additional Bitcoin based on the average price of Bitcoin during the month. This equates to approximately 173 of Bitcoin-equivalent production in February 2024, down approximately 14% from Bitcoin-equivalent production in January 2024. Two fewer days in the month contributed to a 7% reduction in Bitcoin mined, the increase in network hash rate contributed to a 9% reduction, and lower transaction fees contributed to a 6% reduction. Adjusting for these items, Bitcoin-equivalent production would have increased 7% from January, which was largely driven by the installation of the 5,000 newly delivered miners that are now hashing. The Company generated an estimated $7.9 million of revenue during February, down approximately 1% from January 2024. While the aforementioned decline in Bitcoin production and slightly lower energy revenue were headwinds, they were largely offset by the 16% increase in Bitcoin price.

Stronghold Carbon Capture Update

Stronghold has continued to progress the development of its carbon capture project. As previously announced, recent test results from the Scrubgrass Plant have demonstrated carbonation of up to 14% by starting weight of ash, up from prior estimates of up to 12%. Puro registered the Company’s carbon capture project at the Scrubgrass Plant in late February. The Company will now undertake the audit process with Puro, with the goal of accreditation as early as the end of the second quarter of 2024. Please see the presentation posted to the Company’s website on December 12, 2023, and the Company’s Quarterly Report on Form 10-Q dated November 14, 2023, for additional details and assumptions relating to the carbon capture project.

In partnership with Karbonetiq, Inc., the second Karbolith has been installed at the Scrubgrass Plant, and includes structural and design enhancements aimed to increase airflow and carbonation such as increased height, a third window unit, and additional perforated pipes with more outlets connecting to foundation. Each of the enhancements were added while reducing costs and construction time. The second Karbolith had an equipment cost of $33,000, a reduction of approximately 50% when compared to the first Karbolith.

Liquidity and Capital Resources

As of December 31, 2023, and February 29, 2024, we had approximately $7.4 million and $10.2 million, respectively, of cash, cash equivalents, and Bitcoin on our balance sheet, which included approximately 77 Bitcoin and 5 Bitcoin, respectively. As of December 31, 2023, and February 29, 2024, the Company had principal amount of outstanding indebtedness, excluding financed insurance premiums, of approximately $56.5 million and $55.8 million, respectively. Stronghold currently has approximately $0.7 million of remaining capital expenditures required related to its previously announced miner purchase agreements in 2024, and currently has no material capital commitments beyond June of 2024. As of February 29, 2024, Stronghold had approximately $3.4 million of capacity remaining under its at-the-market offering agreement (“ATM”) with H.C. Wainwright & Co., LLC. In 2023, Stronghold issued approximately $11.6 million of Class A common stock at an average price of $6.47 per share under its ATM for approximately $11.2 million of net proceeds, with approximately $0.4 million paid in commissions. The Company has not sold any of its shares under the ATM since the end of the fourth quarter of 2023.

Cautionary Statement Concerning Forward-Looking Statements

Certain statements contained in this press release, including guidance, constitute “forward-looking statements.” within the meaning of the Private Securities Litigation Reform Act of 1995. You can identify forward-looking statements because they contain words such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases which are predictions of or indicate future events or trends and which do not relate solely to historical matters. Forward-looking statements and the business prospects of Stronghold are subject to a number of risks and uncertainties that may cause Stronghold’s actual results in future periods to differ materially from the forward-looking statements, including with respect to its potential carbon capture initiative. These risks and uncertainties include, among other things: the hybrid nature of our business model, which is highly dependent on the price of Bitcoin; our dependence on the level of demand and financial performance of the crypto asset industry; our ability to manage growth, business, financial results and results of operations; uncertainty regarding our evolving business model; our ability to retain management and key personnel and the integration of new management; our ability to raise capital to fund business growth; our ability to maintain sufficient liquidity to fund operations, growth and acquisitions; our substantial indebtedness and its effect on our results of operations and our financial condition; uncertainty regarding the outcomes of any investigations or proceedings; our ability to enter into purchase agreements, acquisitions and financing transactions; public health crises, epidemics, and pandemics such as the coronavirus pandemic; our ability to procure crypto asset mining equipment from foreign-based suppliers; our ability to maintain our relationships with our third-party brokers and our dependence on their performance; our ability to procure crypto asset mining equipment including to upgrade our current fleet; developments and changes in laws and regulations, including increased regulation of the crypto asset industry through legislative action and revised rules and standards applied by The Financial Crimes Enforcement Network under the authority of the U.S. Bank Secrecy Act and the Investment Company Act; the future acceptance and/or widespread use of, and demand for, Bitcoin and other crypto assets; our ability to respond to price fluctuations and rapidly changing technology; our ability to operate our coal refuse power generation facilities as planned; our ability to remain listed on a stock exchange and maintain an active trading market; our ability to avail ourselves of tax credits for the clean-up of coal refuse piles; legislative or regulatory changes, and liability under, or any future inability to comply with, existing or future energy regulations or requirements; our ability to replicate and scale the carbon capture project; our ability to manage costs related to the carbon capture project; and our ability to monetize our carbon capture project, including through the private market and our ability to qualify for, obtain, monetize or otherwise benefit from the Puro registry and Section 45Q tax credits. More information on these risks and other potential factors that could affect our financial results are included in our filings with the Securities and Exchange Commission, including in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of our Annual Report on Form 10-K filed on April 3, 2023, and in our subsequently filed Quarterly Reports on Form 10-Q. The Company expects to file its Annual Report on Form 10-K for the fiscal year 2023 on or around March 8, 2024. Any forward-looking statement or guidance speaks only as of the date as of which such statement is made, and, except as required by law, we undertake no obligation to update or revise publicly any forward-looking statements or guidance, whether because of new information, future events, or otherwise.

In January 2021, the Internal Revenue Service issued final regulations under Section 45Q of the Internal Revenue Code, which provides a tax credit disposed of in secure geological storage (in the event of direct air capture that results in secure geological storage, credits are valued at $180 per ton of carbon dioxide (“CO2” captured) or utilized in a manner that satisfies a series of regulatory requirements (in the event of direct air capture that results in utilization, credits are valued at $130 per ton of CO2 captured). We may benefit from Section 45Q tax credits only if we satisfy the applicable statutory and regulatory requirements, and we cannot make any assurances that we will be successful in satisfying such requirements or otherwise qualifying for or obtaining the Section 45Q tax credits currently available or that we will be able to effectively benefit from such tax credits. Additionally, the amount of Section 45Q tax credits from which we may benefit is dependent upon our ability to satisfy certain wage and apprenticeship requirements, which we cannot assure you that we will satisfy. We are currently exploring whether our carbon capture initiatives discussed herein would be able to qualify for any Section 45Q tax credit. It is not entirely clear whether we will be able to meet any required statutory and regulatory requirements, and qualification for any amount of Section 45Q credit may not be feasible with our currently planned direct air capture initiative. Additionally, the availability of Section 45Q tax credits may be reduced, modified or eliminated as a matter of legislative or regulatory policy. Any such reduction, modification or elimination of Section 45Q tax credits, or our inability to otherwise benefit from Section 45Q tax credits, could materially reduce our ability to develop and monetize our carbon capture program. These and any other changes to government incentives that could impose additional restrictions or favor certain projects over our projects could increase costs, limit our ability to utilize tax benefits, reduce our competitiveness, and/or adversely impact our growth. Any of these factors may adversely impact our business, results of operations and financial condition.

⁽¹⁾ The diluted earnings per share for the three months ended December 31, 2023, reflects the potential dilutive impact of Series D convertible preferred stock using the as-if converted method and excludes the associated deemed contribution from the exchange of Series C convertible preferred stock. The same effect has been excluded from diluted earnings per share for the twelve months ended December 31, 2023, because the impact would be antidilutive.

Use and Reconciliation of Non-GAAP Financial Measures

This press release and our related earnings call contain certain non-GAAP financial measures, including Adjusted EBITDA, as a measure of our operating performance. Adjusted EBITDA is a non-GAAP financial measure. We define Adjusted EBITDA as net income (loss) before interest, taxes, depreciation and amortization, further adjusted by the removal of one-time transaction costs, impairments on digital currencies, realized gains and losses on the sale of long-term assets, expenses related to stock-based compensation, gains or losses on derivative contracts, gains or losses on extinguishment of debt, realized gains or losses on sale of digital currencies, or changes in fair value of warrant liabilities in the period presented. See reconciliation below.

Our board of directors and management team use Adjusted EBITDA to assess our financial performance because they believe it allows them to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure (such as varying levels of interest expense and income), asset base (such as depreciation, amortization, impairments, realized gains on digital assets and realized gains and losses on the sale of long-term assets) and other items (such as one-time transaction costs, expenses related to stock-based compensation, and gains and losses on derivative contracts) that impact the comparability of financial results from period to period. We present Adjusted EBITDA because we believe it provides useful information regarding the factors and trends affecting our business in addition to measures calculated under GAAP. Adjusted EBITDA is not a financial measure presented in accordance with GAAP. We believe that the presentation of this non-GAAP financial measure will provide useful information to investors and analysts in assessing our financial performance and results of operations across reporting periods by excluding items we do not believe are indicative of our core operating performance. Net income (loss) is the GAAP measure most directly comparable to Adjusted EBITDA. Our non-GAAP financial measure should not be considered as an alternative to the most directly comparable GAAP financial measure. You are encouraged to evaluate each of these adjustments and the reasons we consider them appropriate for supplemental analysis. In evaluating Adjusted EBITDA, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in such presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. There can be no assurance that we will not modify the presentation of Adjusted EBITDA in the future, and any such modification may be material. Adjusted EBITDA has important limitations as an analytical tool, and you should not consider Adjusted EBITDA in isolation or as a substitute for analysis of our results as reported under GAAP. Our presentation of Adjusted EBITDA should be read in conjunction with the financial statements furnished in our Form 10-K for the fiscal year ended December 31, 2023, expected to be filed on or around March 8, 2024. Because Adjusted EBITDA may be defined differently by other companies in our industry, our definition of this non-GAAP financial measure may not be comparable to similarly titled measures of other companies, thereby diminishing its utility.

⁽¹⁾ Includes the following non-recurring expenses: out-of-the-ordinary major repairs and upgrades to the power plant, settlement expenses from terminating the Northern Data hosting agreement, legal fees related to the extinguishment of the NYDIG debt, and other one-time items.
