Stronghold Announces Third Quarter 2023 Operating and Financial Results and

Launches Carbon Capture Initiative

Stronghold to Hold Analyst and Investor Day on December 12, 2023

NEW YORK, November 14, 2023Stronghold Digital Mining, Inc. (NASDAQ: SDIG) (“Stronghold”, the “Company”, or “we”) today announced the following:

Recent Operational and Financial Highlights
 

Stronghold’s Beneficial Use Ash Can Capture Carbon Dioxide (CO2). Following four months of extensive testing, third-party lab results indicate that Stronghold’s beneficial use ash, a natural byproduct of its mining-waste-to-power process, can capture CO2 from ambient air at a capacity of up to 12% by weight of starting ash. The process results in permanent and stable storage of the CO2.
 

Initial Phase of Carbon Capture Project Underway at the Scrubgrass Plant. Stronghold and third-party engineering, design, and construction partners have developed direct air capture (“DAC”) technology to utilize the beneficial use ash to capture CO2. Field testing is in progress with initial results expected by December of 2023.
 

Reiterating Q4 2023 Hash Rate Guidance. The Company is committed to Bitcoin mining and expects at least 20% sequential growth in hash rate going into the fourth quarter of 2023.
 

Procured 3,135 High-Spec Bitcoin Miners (358 PH/s, >114 TH/s per miner, 28.7 J/T) Since the End of Q2 2023. The Company is taking a disciplined approach to the Bitcoin  event in April of 2024, with no incremental capital currently committed to purchase additional miners.
 

Signed Managed Services Agreement with Frontier Outpost 8, LLC (“Frontier Mining”) to optimize Bitcoin mining operations and profitability of Stronghold’s data centers.
 

Fixed Costs Were Down ~$31 Million for the First Three Quarters of 2023 Versus the First Three Quarters of 2022, Representing a ~56% Reduction. Fixed costs include operations & maintenance expense and general & administrative expense, excluding stock-based compensation and a one-time accounts receivable adjustment.
 

Generated 620 Bitcoin during the third quarter of 2023, which was nearly flat versus the second quarter of 2023 and represented approximately 9% and 41% growth compared to the third and fourth quarters of 2022, respectively.
 
1 See Non-GAAP Reconciliation table.
 


The Company generated revenues of $17.7 million, net loss of $22.3 million, and non-GAAP Adjusted EBITDA loss of $2.4 million during the third quarter of 2023. Excluding the adjustment to accounts receivable, the non-GAAP Adjusted EBITDA loss would have been $1.6 million. Revenues comprised $12.7 million from cryptocurrency self-mining, $3.8 million from cryptocurrency hosting, and $1.2 million from the sale of energy.1

Stronghold Carbon Capture Initiative

On November 10, 2023, Stronghold launched the first phase of its carbon capture project at the Scrubgrass Plant. The design and process follow four months of third-party laboratory tests, conducted by Karbonetiq, Inc. (“Karbonetiq”) at their Santa Barbara, California lab, utilizing a variety of testing methodologies. Stronghold’s beneficial use ash naturally contains reactive calcium oxide as a result of including limestone in the fuel mix to reduce sulfur dioxide emissions given high sulfur content in mining waste. Calcium oxide can, under the right conditions, bond with CO2 to form calcium carbonate, effectively absorbing CO2 out of ambient air and permanently storing it in a geologically stable solid. Karbonetiq’s lab results demonstrated that Stronghold’s beneficial use ash can potentially capture CO2 at a capacity of approximately 12% by weight of starting ash with the use of their proprietary, patent pending, direct air capture technology. We believe that the carbonation will occur in no more than two weeks based on the lab results. As part of the first phase of development, Stronghold aims to confirm that laboratory results are replicable and scalable in the field. The Company  expects to use third-party labs with industry-standard thermogravimetric analysis - mass spectrometry (TGA-MS) measurements to test ash samples following exposure to Karbonetiq’s proprietary, patent pending process. Stronghold expects that development will be iterative, as the Company works to optimize processes around ash movement, composition, rate of capture, time to capture and cost, among other variables. The cost of equipment for the first phase is expected to be less than $100,000, and the Company believes that the scaled project will cost approximately $50-125 per annual ton of CO2 capture capacity, assuming the laboratory results are validated.

Stronghold’s two mining-waste-to-power facilities produce approximately 800,000 to 900,000 tons of beneficial use ash per year at baseload capacity utilization. Extrapolating the potential 12% CO2 capture capacity from Scrubgrass ash lab tests, this would imply potential to capture approximately 100,000 tons of CO2 per year. In September of 2023, Stronghold engaged third-party consultant Carbonomics to advise on the verification of its carbon removals for private-market monetization. The Company believes that its process will qualify for the Carbonated Materials Methodology for CO2 Removal on the Puro Registry, and the average transaction price for Puro’s Carbon Removal Certificates has ranged from approximately $130 to 190 per ton of CO2 removed during 2023. Stronghold expects to submit a Project Design Document to Puro by the first quarter of 2024. Additionally, the Company intends for its process to qualify for the direct air capture standard under the recently enacted Internal Revenue Service (“IRS”) Section 45Q and the Inflation Reduction Act, which can provide for up to $180/ton tax credits based on existing incentives. The Company is currently exploring whether its carbon capture initiatives would be able to qualify for Section 45Q tax credits.

“Our focus on improving the environment is a key component of our business,” said Greg Beard, chairman and chief executive officer of Stronghold. “Mining waste piles, if left in their dormant states, will remain ‘forever emitters’ of greenhouse gasses, including CO2, methane, and other air pollutants. In the last year, multiple third-party studies found that greenhouse gas emissions from unabated mining waste piles greatly exceeds the corresponding emissions under the controlled and regulated conditions of mining-waste-to-power CFB and similar facilities. Specifically, one study estimates that mining-waste-to-power facilities in Pennsylvania and West Virginia alone ‘reduce the equivalent net GHG emissions that would otherwise be emitted from the same amount of coal refuse by over 20 million tons of CO2e in a single year’. This is an exciting affirmation of our efforts, and, with the deployment of our carbon capture project, we have the opportunity to make even more progress in combating greenhouse gas emissions.


“While it is early, if the lab results are replicable in the field using direct air capture technology, when scaled, our carbon capture deployment has the potential to be one of the ten largest DAC projects currently announced in the U.S.,” Beard continued. “We are optimistic that this meaningful project can become operational for a fraction of the cost of the other announced projects and believe that it could be deployed at scale on a shorter timeline. We look forward to providing updates as we receive test results and the project progresses.”

Bitcoin Mining Update

Stronghold generated 620 Bitcoin during the third quarter of 2023, which was nearly flat versus the second quarter 2023 and represented approximately 9% and 41% growth compared to the third and fourth quarters of 2022, respectively. The Company achieved this growth despite the average network hash rate in the third quarter of 2023 being 83% and 52% higher than the average network hash rate in the third quarter and fourth quarter of 2022, respectively. Network hash rate grew ~9% sequentially from the second quarter of 2023 to the third quarter 2023.

The Panther Creek Plant entered its planned 15-day outage on October 28, 2023, and the Company intended to import electricity from the PJM grid to power its Panther Creek data center during that time. The Panther Creek Plant notified PJM of this outage, as is customary. Shortly after the outage began, the Panther Creek Plant was notified by PJM that there was a reliability issue elsewhere in the region that would constrain Panther Creek’s electricity imports to 30 megawatts through its outage, less than half of its need. As a result, the Company took steps to shorten the outage, and the Panther Creek Plant restarted on November 9, 2023, and the data center resumed unconstrained operations shortly thereafter.


Liquidity and Capital Resources

As of September 30, 2023, and November 10, 2023, we had approximately $5.6 million and $5.2 million, respectively, of cash and cash equivalents and Bitcoin on our balance sheet, which included 24 Bitcoin and 12 Bitcoin, respectively. Additionally, Stronghold has $3.8 million of contracted receivables that it expects to receive in the next 30 days, including approximately $2.7 million related to the sale of 2022 waste coal tax credits and approximately $0.8 million related to the sale of renewable energy credits. As of September 30, 2023, and November 10, 2023, the Company had principal amount of outstanding indebtedness of approximately $59.7 million and $59.6 million, respectively. As of November 10, 2023, Stronghold had approximately $6.1 million of capacity remaining of its at-the-market offering agreement (“ATM”) with H.C. Wainwright & Co., LLC. Stronghold has issued approximately $8.9 million of Class A common stock at an average price of $6.96 per share under its ATM for approximately $8.6 million of net proceeds, with approximately $0.3 million paid in commissions. The Company has not sold any of its shares under the ATM since the end of the third quarter of 2023.

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; 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 Section 45Q tax credits. More information on these risks and other potential factors that could affect our financial results is 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. 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 IRS 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 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.

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, 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 and should be read in conjunction with the financial statements furnished in our Form 10-Q for the quarter ended September 30, 2023, expected to be filed on or prior to November 14, 2023. 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.

Exhibit 99.2

 Carbon Capture Initiative and Q3 2023 Earnings  November 2023 
 

 Disclaimer  2  Forward-Looking Statements  The information, financial projections and other estimates contained herein contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, and future guidance with respect to the anticipated future performance of the Company and its potential carbon capture initiative. Such financial projection, guidance, and estimates are as to future events and are not to be viewed as facts, and reflect various assumptions of management of the Company concerning the future performance of the Company and are subject to significant business, financial, economic, operating, competitive and other risks and uncertainties and contingencies (many of which are difficult to predict and beyond the control of the Company) that could cause actual results to differ materially from the statements and information included herein. Forward-looking statements may include statements about various risks and uncertainties, including those described under the heading "Risk Factors“ in our previously filed Annual Report on Form 10-K, filed on April 3, 2023, and in our subsequently filed Quarterly Reports on Form 10-Q.  In addition, such information, financial projections, guidance and estimates were not prepared with a view to public disclosure or compliance with published guidelines of the SEC, the guidelines established by the American Institute of Certified Public Accountants or U.S. generally accepted accounting principles (“GAAP”). Accordingly, although the Company’s management believes the financial projections, guidance and estimates contained herein represent a reasonable estimate of the Company’s projected financial condition and results of operations based on assumptions that the Company’s management believes to be reasonable at the time such estimates are made and at the time the related financial projections and estimates are disclosed, there can be no assurance as to the reliability or correctness of such information, financial projections and estimates, nor should any assurances be inferred, and actual results may vary materially from those projected.  Section 45Q  In January 2021, the IRS issued final regulations under Section 45Q of the Internal Revenue Code, which provides a tax credit for qualified CO2 that is captured using carbon capture equipment and 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 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, including but not limited to compliance with wage and apprenticeship requirements to receive the $180/ton tax credits, 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. We are currently exploring whether our carbon capture initiatives discussed herein would be able to qualify for any 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 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. Any of these factors may adversely impact our business, results of operations and financial condition.  Non-GAAP Measures  This presentation includes financial measures that are not presented in accordance with GAAP. While management believes such non-GAAP measures are useful, it is not a measure of our financial performance under GAAP and should not be considered in isolation or as an alternative to any measure of such performance derived in accordance with GAAP. These non-GAAP measures have limitations as analytical tools and you should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP. The reconciliations for non-GAAP figures to applicable GAAP measures are included in the Appendix.  We have not reconciled non‐GAAP forward-looking measures, including Adjusted EBITDA guidance, to their corresponding GAAP measures due to the high variability and difficulty in making accurate forecasts and projections, particularly with respect to the price of Bitcoin, Bitcoin network hash rate, electricity prices, plant outages, power input costs, [and our proposed carbon capture initiative], which are difficult to predict and subject to change. Accordingly, such reconciliations of non-GAAP forward-looking measures are not available without unreasonable effort.  Third-Party Information  Certain information contained herein refers to or has been derived from sources prepared by third parties. While such information is believed to be reliable for the purposes used herein, none of the Company or any of its affiliates, directors, officers, employees, members, partners, shareholders or agents make any representation or warranty with respect to the accuracy or completeness of such information. Although the Company believes the sources are reliable, it has not independently verified the accuracy or completeness of data from such sources. Additionally, descriptions herein of market conditions and opportunities are presented for informational purposes only; there can be no assurance that such conditions will actually occur or result in positive returns. Recipients of this presentation should make their own investigations and evaluations of any information referenced herein. The recipient should not construe the contents of this presentation as legal, tax, accounting or investment advice or a recommendation. The recipient should consult its own counsel, tax advisors and financial advisors as to legal and related matters concerning the matters described herein. By reviewing this presentation, the recipient confirms that it is not relying upon the information contained herein to make any decision. This presentation does not purport to be all-inclusive or to contain all of the information that the recipient may require to make any decision.  See Key Assumptions on page 24 
 

 Stronghold at a Glance  The only environmentally beneficial and vertically integrated public Bitcoin mining company  Note: all data as of 11/10/23 unless otherwise noted; all figures approximated  NASDAQ Ticker Symbol  SDIG  Share Price  $3.89  Bitcoin Mined (Q3 2023)  ~620  Deployed Hash Rate Capacity  4.0 EH/s  Owner of two mining waste reclamation facilities: Scrubgrass and Panther Creek  165 MW of net power generation capacity  >40,000 miners delivered and funded  ~25 MW of data center equipment inventory  Nearly 1,700,000 tons of mining waste removed from the environment since beginning of 2022  3 
 

 1. Assumes a $0.075 hash price (see Appendix for information about hash price and how it is calculated), $42.50/MWh cost of power, and 34 J/T average miner efficiency  Developed first-generation direct air capture (“DAC”) technology with partners to facilitate carbonation, with initial unit deployed at Scrubgrass  Entered into agreement with best-in-class, established operator, Frontier Mining, to manage data centers and enhance Bitcoin mining operations in October 2023  Observing improvements in miner performance and  process efficiency  Agreement terms incentivize Frontier and include fee adjustments based on Bitcoin mining economics  Continuing to evaluate prudent hash rate growth into the April 2024 halving: potential third data center (discussions ongoing) vs. selective high-grading of miners at current sites (no additional capex committed currently)  With 4 EH/s of current hash rate capacity, every 1% of incremental uptime could yield over $500k of annual cash flow 1;  potential for 5-10% uptime  gain in near future  Optimizing Bitcoin Mining Operations  Scrubgrass ash can capture CO2 at up to 12% by starting weight based on third-party lab tests  Capturing CO2 with Ash Byproduct  Unlocking Significant Value From Substantial Asset Base  3 
 

 Stronghold Carbon Capture  3 
 

 The New Carbon Market  Private markets and the federal government have developed significant incentives for those who capture carbon and/or reduce carbon emissions  Projects that capture carbon are eligible to sell carbon credits and may be suitable to receive 45Q tax credits  1. See: “The Inflation Reduction Act: Here’s what’s in it.” McKinsey & Company, 24 Oct. 2022, https://www.mckinsey.com/industries/public-sector/our- insights/the-inflation-reduction-act-heres-whats-in-it  Businesses and organizations purchase credits from carbon capture projects to offset their emissions  Registries verify environmental benefits, methodologies, and viability of projects (effectively accrediting the associated credits)  Credits validated by the most established registries (which typically have the most thorough registration processes) generally trade at premium to other credits  Contains ~$500 billion in new spending and tax incentives primarily focused on clean energy and healthcare  Nearly $400 billion in spending and incentives target climate and clean energy initiatives  Expands IRS Section 45Q incentives, which can be realized as direct-pay tax credits for qualifying carbon capture projects; credits for direct air capture can reach  $180 per ton of CO2 captured  Inflation Reduction Act  (“IRA”) 1  Voluntary Carbon Market  3 
 

 Stronghold’s Beneficial Use Ash  Can Capture Carbon  Financially Transformative  Potential to drive up to ~$30mm of incremental annual EBITDA and reduce Stronghold’s  net cost of power to as low as ~$16/MWh 2  Low Technology Risk  Carbon capture process is largely a combination of basic chemistry and airflow  Large-Scale CO2 Removal  Potential to capture up to  ~100k tons of CO2 from ambient air annually by end of 2024 1  See inputs and assumptions on page 13  See inputs and assumptions on pages 14-15; assumes receipt of 45Q tax credits; see Disclaimer page for details and risks associated with 45Q; it is currently uncertain whether we will be successful in monetizing our carbon program  3 
 

 Stronghold owns two circulating fluidized bed (“CFB”) mining waste reclamation and power generation facilities:  Scrubgrass  (~85 MW of net output capacity)  Panther Creek  (~80 MW of net  output capacity)  Carbon County  Venango  County  Our Business Model  Partner with PA DEP to reclaim land, and generate power (under a Title V EPA permit) that is used to mine Bitcoin and supply power to the PJM grid  facilitating revegetation  Note: See Appendix for more information on mining waste  8  Primary source of energy for these facilities is mining waste (coal refuse), sourced from the reclamation of some of the  840+ mining waste piles littered across Pennsylvania, an unfortunate legacy byproduct of centuries of coal mining  CFB power generation process removes this harmful waste from the environment – reducing water pollution, land pollution, and air emissions from mining waste piles – and converts it into electricity (the primary product) and beneficial use ash  (a byproduct)  CFB fuel mix neutralizes sulfur dioxide (SO2) with limestone and creates a calcium-rich, basic (high-PH) ash, most of which is currently returned to mining waste piles to reclaim land,

(QEP), and Patrick Fennell (PE). “Net Air Emission Benefits from the Remediation of Abandoned Coal Refuse Piles.” TRC Environmental Inc., March 2023, p. 2,  The coal refuse reclamation-to-energy facilities in Pennsylvania (PA) and West Virginia (WV) alone reduce the equivalent net GHG emissions that would otherwise be emitted from the same amount of coal refuse by over 20 million tons of CO2 [equivalent] in a single year. 2  Each ton of coal refuse is expected to produce GHG emissions between 2.43 and 6.44 tons CO2, [equivalent] with a net reduction of between 1.16 and 5.17 tons CO2 [equivalent] per ton of coal refuse reclaimed by the coal refuse [reclamation-to-energy] industry. 1  Third-Party Studies Support That Mining-Waste-to-Power Activities Are Net Carbon Negative, Reducing Net GHG Emissions by 50-80% 1  https://strongholddigitalmining.com/wp-content/uploads/2023/11/TRC-Environmental-Inc.-March-2023.pdf  9 
 

 Introducing Stronghold Carbon Capture  Worked with construction, design, and engineering partners to develop direct air capture (“DAC”) technology that utilizes the stack effect to drive air through ash  First DAC unit installed at Scrubgrass on Nov. 10th  Third-party lab results over last 4 months, utilizing 3 separate testing methods, indicate that our ash can capture CO2 at a capacity of up to 12% by weight of starting ash 1  1. Actual CO2 absorption may vary, including by site, type of ash, arrangement of ash, and weather conditions  10 
 

 Engaged CO2 mineralization expert Karbonetiq in June 2023 to explore  carbon capture opportunities with our ash  Conducted numerous third-party lab tests with ash from Scrubgrass – results demonstrate that ash can capture up to 12% of its weight in CO2 from ambient air  Designed KarbolithTM direct air capture equipment, which drives airflow through ash  to facilitate carbonation  Installed first KarbolithTM at Scrubgrass on November 10th, with <$100k equipment cost  Potential for Best-in-class capital efficiency, currently estimated at $50-125 per ton of annual CO2 capture capacity 3  11  Engaged environmental consulting firm Carbonomics in September 2023 to advise on carbon capture verification, documentation, and listing our project on a carbon registry to monetize CO2 removals in private carbon markets  Identified Puro Registry’s existing Carbonated Materials methodology as applicable for  our project  Submitted concept paper to Puro for initial feedback in October 2023; planning to  submit formal Project Design Document with aim of having project listed by Q1 2024  Planning to use third party certified labs to measure and verify CO2 removals using standard TGA-MS and QXRD methods starting with Phase I  Ash comprises both bottom ash and fly ash; Stronghold is in the process of determining the best mixture of bottom ash and fly ash for capture purposes, but both have been proven to capture carbon; historically, there have been times when the plants did not operate at baseload capacity utilization  Ash may release CO2 in the remote event that it is exposed to extreme heat (1,500 degrees Fahrenheit) or hydrochloric acid  Reflects management’s current estimates, subject to potentially significant change based on labor requirements, construction and materials costs, verification equipment. and number of Karboliths required, among other factors  Complementary, Capital-Efficient, and Near-Term Direct Air Capture Opportunity  Scrubgrass and Panther Creek estimated to produce ~800-900k metric tons of beneficial use ash per year when operating at baseload capacity 1  Ash contains reactive calcium oxide (CaO), which bonds with CO2 to form calcium carbonate (CaCO3), effectively pulling CO2 out of the air  – this bond is permanent and  geologically stable  2 
 

 Process Expected to Dramatically Increase CO2 Removals  Ash may release CO2 in the remote event that it is exposed to extreme heat (1,500 degrees Fahrenheit) or hydrochloric acid  Design subject to change based on results from initial units; contemplating larger structure (up to ~50 feet) to evaluate how size of the unit impacts carbon capture results  Ash is dispensed from facilities  Most ash is promptly transported back to mining waste piles, replacing the waste as it is extracted, until fully reclaimed  Ash is packed into ground and covered with soil to revegetate land  Ash is dispensed from facilities  Ash is immediately directed to a field and methodically spread out among KarbolithsTM to maximize aeration  KarbolithsTM drive airflow through ash,  facilitating permanent and secure  carbonation  After carbonation has occurred, CO2 removals are quantified, and most ash is transported back to mining waste piles  Ash is packed into ground and covered with soil to revegetate land (working on alternative uses as well)  CO2 is permanently and securely stored 1  Status Quo Process  1  2  3  1  2  3  4  5  6  Note: Given ash’s limited exposure to  air, little carbonation occurs  First Installed KarbolithTM 2  ~25-foot structure uses stack effect to drive ambient air through ash  Expected Process with Carbon Capture  13

 Appendix  Mining Waste Overview  20 
 

 Mining Waste  A Widely Ignored Environmental Disaster  Mining waste is the disregarded byproduct of  centuries of coal mining  20  Brought up from underground and left on the surface during mining process, exposing it to the atmosphere and placing it above the water table 
 

 Pennsylvania mining communities were instrumental in building America  There are over 840 toxic mining waste piles in Pennsylvania, and these large mountains of waste pollute the land, water, and air  The aftermath: these communities were stripped of their  natural resources and  jobs and left with this toxic waste in their backyards  If left alone, these piles emit CO2, particulates, and volatile organic compounds (benzene, toluene, ethylbenzene, xylenes, hexane, cyclohexane, naphthalene, and acrolein) into the atmosphere 1  20  Piles spontaneously combust, releasing more harmful emissions – Pennsylvania DEP estimated that ~40 piles were burning continually in 2020 2  Acid mine drainage from mining waste piles is one of the largest sources of water pollution in Pennsylvania  See: “Coal Refuse Whitepaper.” ARIPPA, p. 5, http://arippa.org/wp-content/uploads/2018/12/ARIPPA-Coal-Refuse-Whitepaper-with-Photos-10_05_15.pdf  See: Prepared Testimony of Patrick McDonnell, Secretary, Pennsylvania Department of Environmental Protection, before the Joint Legislative Air and Water Pollution Control and Conservation Committee, 3 Feb. 2020, p. 1, https://files.dep.state.pa.us/aboutdep/Testimony/2020/2020.02.03_JLCC_Waste_Coal_Hearing_DEP_Testimony.pdf 
 

 Over 5,500  miles of waterways impaired 1  Acid mine drainage from mining waste piles is among the 2 largest known pollutants of waterways in Pennsylvania 1  Causes rivers to run orange  Highly detrimental to aquatic life  Problem is severe and widespread and threatens water supply downstream, with all impacted streams within or extending to all major river basins in Pennsylvania, which ultimately extend to the Chesapeake Bay, Delaware River, Ohio, Mississippi, and Gulf of Mexico watersheds  1. See: “2022 Pennsylvania Integrated Water Quality Report.” Pennsylvania Department of Environmental Protection, 2022, https://storymaps.arcgis.com/stories/b9746eec807f48d99decd3a583eede12  20 
 

 Piles spontaneously combust through oxidation and lightning strikes  Multiple large piles have burned for decades  When burning, piles release toxic, uncontrolled emissions into atmosphere: hydrogen sulfide, sulfur dioxide, ammonia, oxides of nitrogen, particulates, carbon monoxide, and CO2 1  Estimated that nearly 7 million tons of mining waste burn each year in Pennsylvania in unintended, uncontrolled fires, releasing ~9 million tons of CO2 and numerous other air pollutants without any emissions controls 2,3  All mining waste piles have burned, are burning, or are likely to burn… unless they are reclaimed  See: “Coal Refuse Whitepaper.” ARIPPA, p. 5, http://arippa.org/wp-content/uploads/2018/12/ARIPPA-Coal-Refuse-Whitepaper- with-Photos-10_05_15.pdf  Estimates provided by the Pennsylvania DEP in 2016  See: “Economic and Environmental Analysis of Pennsylvania’s Coal Refuse Industry.” Econsult Solutions, Inc., 8 Sep. 2016,  p. 13, https://www.congress.gov/116/meeting/house/110202/witnesses/HHRG-116-II06-Wstate-HughesR-20191114-SD017.pdf  20 
 

 Mining Waste Reclamation Is the Foundation of Our Business  We believe that power generation with CFB facilities is the only practical way to solve Pennsylvania’s toxic mining waste problem, and Stronghold has already reclaimed over 1,050 acres of previously unusable land.  Reclamation Process  Remove toxic mining waste from environment  1  Generate energy from mining waste through highly specialized process that can eliminate most harmful emissions:  2  3  Utilize ash byproduct in reclamation and carbon capture projects  B E F O R E  A F T E R  ~90% of NOx emissions  2  ~98% of SO emissions  ~99.9% of particle  ~99.9% of mercury  CFB facilities were purpose-built for Pennsylvania to solve mining waste problem  At the time, construction was only economically feasible through above-market power purchase agreements  Today, process has bipartisan support in Pennsylvania – we receive alternative energy credits and waste coal tax credits to perform this vital work  Operate at the direction of and in partnership with  Pennsylvania DEP to reclaim mining waste piles  20 
 

 CFB Power Generation Process  Using CFB facilities is only way to generate power with low-BTU toxic mining waste  Traditional thermal coal has ~12,000 BTU/lb heat content; mining waste has ~5,500 BTU/lb heat content  Pushing air through circulating mining waste effectively fluidizes material and enables combustion  Beneficial Use Ash  Currently, majority of ash is returned to mining waste piles to facilitate reclamation  Basic nature of ash offsets acidic nature of  the sites, facilitating vegetation and life  Ash used to fill in the sites and is subsequently covered with soil and seeded until fully reclaimed  Calcium content of ash also facilitates absorption of CO2, which is the focus of our carbon capture efforts  Mining Waste, Limestone  Electricity (Product)  I N P U T S  O U T P U T S  Beneficial Use Ash (Byproduct)  Limestone added to feedstock to mitigate SO2 emissions (calcium in limestone absorbs sulfur)  Resulting ash byproduct is a beneficial use ash – it is basic and a certified liming agent  MINING WASTE  20 
 

 Carbon Capture Key Assumptions  Tons of CO2 Captured  Total ash production of 800-900k metric tons at baseload capacity utilization  8-12% CO2 capture by weight of ash  Implies ~60-100k tons of CO2 captured  Multiple Income  Streams  Private Market: $120-200/ton, beginning  2024, reaching capacity in 2025  IRS 45Q: $180/ton, if qualified with earliest in 2025, more likely 2026  Operating Expenses  10% of carbon credit gross proceeds and 5% of 45Q tax credit proceeds paid out in the form of fees and royalties  Annual fixed opex of $1.5mm (includes personnel and equipment leasing)  Variable opex of $30 per ton of CO2 captured  No incremental G&A  Capital Expenditures  100-150 KarbolithsTM @ $40-60k per KarbolithTM for equipment  $1-2mm for labor/construction  20

 Hash Price Calculation  Note: Hash price per daily Bitcoin price and network hash rate calculated from difficulty  Note: Bitcoin mining revenue is based on a hash price on $ per terahash per second (“TH/s”) per day. Hash price represents global Bitcoin mining revenue per TH/s of network hash rate, incorporates both Bitcoin price and network hash rate and it is calculated as follows: [Bitcoin price] x [number of Bitcoins mined per day (~900)] x [1 + transaction fee %] ÷ [network hash rate (TH/s)]  1. Current block subsidies are 6.25 BTC  Bitcoin Price  Mining Rewards  6.25 BTC 1 / block × (1+transaction fee %)  144  blocks per day  Divided by:  Network Hash Rate (TH/s)  The metric that drives BTC mining revenue, reflecting both BTC price and network hash rate                                            29
