Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (this “MD&A”) should be read in conjunction with our Condensed Consolidated Financial Statements and the related notes (the “Notes”) and other financial information included elsewhere in this Quarterly Report and with our audited consolidated financial statements for the year ended December 31, 2023, as included in our 2023 Annual Report. This MD&A contains statements of management’s beliefs, expectations and assumptions regarding our future business, and any statements other than statements of historical fact are “forward-looking statements” within the meaning of the PSLRA, which are made in reliance of the safe harbor provisions of Section 27A of the Securities Act, Section 21E of the Exchange Act, and the PSLRA. Such statements express management’s beliefs, opinions, projections and expectations regarding future events and circumstances, based on information available to management as of the date of this Quarterly Report, and are subject to risks and uncertainties, and our actual results could differ materially from those discussed in these forward-looking statements. Further, these forward-looking statements should not be construed either as assurances of performance or as promises of a given course of action. You should review the sections of this Quarterly Report entitled “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” for a discussion of factors that could cause actual results to differ materially – and potentially adversely – from the results described in or implied by the forward-looking statements contained in this MD&A and elsewhere in this Quarterly Report. Unless otherwise indicated, amounts are stated in thousands of U.S. Dollars except for: share, per share, and miner amounts; Bitcoin quantities, prices, and hash rate; cost to mine one Bitcoin; and production value of one Bitcoin mined. Business Overview We are a vertically-integrated Bitcoin mining company principally engaged in enhancing our capabilities to mine Bitcoin in support of the Bitcoin blockchain. Our Rockdale Facility is believed to be the largest Bitcoin mining facility in North America, as measured by developed capacity, and we are currently evaluating further growing its capacity. Additionally, we are developing the Corsicana Facility, a second large-scale Bitcoin mining facility, which, upon completion, is expected to have approximately 1.0 gigawatts (“GW”) of capacity available for our own Bitcoin Mining activities. On July 23, 2024, we completed a transaction to acquire Block Mining, a Kentucky-based vertically-integrated Bitcoin miner consisting of two operational sites, both in Kentucky, totaling 60 MW of operational capacity with potential to expand up to 155 MW. We intend to expand Block Mining’s two sites, targeting 110 MW for self-mining operations by the end of 2024. Additionally, Block Mining owns a greenfield expansion opportunity, adjacent to an existing substation, presenting an opportunity to develop 60 MW and with potential to expand to 150 MW. Block Mining is a capital efficient developer and operator of Bitcoin mining facilities that will add to our ability to execute our leading vertically-integrated strategy. ​ We operate in an environment which is constantly evolving based on the proliferation of Bitcoin and cryptocurrencies in general. A significant component of our strategy is to effectively and efficiently allocate capital between opportunities that generate the highest return on investment. Industry Trends The price of Bitcoin increased during the first quarter of 2024 due to a new source of demand, the eleven Bitcoin spot Exchange Traded Funds (“ETFs”) approved to begin trading by the SEC on January 11, 2024. Significant interest in the ETFs followed their introduction. One such ETF earned recognition as the fastest ETF ever to surpass $10 billion in assets under management since its launch. The ETFs, as an investment vehicle, provided a new access point for investors to gain exposure to Bitcoin through more traditional methods resulting in the ETFs seeing a combined net inflow of approximately $18.5 billion through September 30, 2024. ​ During 2023 and 2024, the Bitcoin mining industry saw record growth as the price of Bitcoin increased from the lows experienced in early 2023. The increasing Bitcoin price renewed opportunities to access capital markets to fund growth, leading to unprecedent expansion in mining operations and resulting in a doubling in the size of provisioned hash calculation services on the network, as measured by total hash rate. Many Bitcoin mining companies heavily invested in infrastructure, upgrading and expanding mining fleets in advance of the April 2024 Bitcoin network halving. We expect competition within the mining industry to continue as long as Bitcoin prices remain elevated or increase further. ​ The Bitcoin mining industry recently experienced an increase in transaction fees on the Bitcoin network, as well as an increase in overall demand for Bitcoin. Various protocols on the Bitcoin network gained popularity during 2023, and at various times temporarily resulted in a significant increase in the transaction fee paid to add a certain Bitcoin transaction to the blockchain. These 33 Table of Contents transaction fees are volatile in nature but are paid directly to miners and are representative of public interest in transacting in Bitcoin. Transaction fees are packaged with the block subsidy issued by the Bitcoin network to combine for the total reward paid to miners upon solving a block. ​ The Bitcoin subsidy issued by the Bitcoin network for solving a block is subject to periodic incremental halving. The network halving is a preprogrammed, fixed process of the Bitcoin network where the Bitcoin subsidy for solving a block received by miners is reduced by half approximately every four years. The network halving is a process designed to implement a periodic decreasing schedule of the issuance of new Bitcoin into the market which results in a predictable and controlled inflationary rate. The network halving will continue to occur on this schedule until the amount of Bitcoin in existence reaches the cap of 21.0 million. Historically, many Bitcoin miners have been a source of selling pressure on Bitcoin as miners have sold their production to fund operations. After each halving, the decrease in the subsidy provided to miners from the Bitcoin network may lead to fewer rewards for miners and thus may result in a decrease in the supply of bitcoin sold by miners into the market. The network halving occurred in April 2024, cutting the subsidy from 6.25 to 3.125 Bitcoin per block. ​ Prior to the halving event, shifts in strategy by prominent Bitcoin miners focused on implementing vertically-integrated business models whereby Bitcoin miners own and operate their own facilities rather than renting out space from a third-party’s data center. Vertical integration provides additional control over operational outcomes as well as better management of any input costs such as power and overhead fees. Flexibility, and the ability to manage expenses, becomes increasingly important as the amount of competition on the Bitcoin network expands and the subsidy in Bitcoin provided by the network contracts decreases. ​ Network difficulty, which is a measure of how hard it is for miners to solve a block on the Bitcoin blockchain (and, thus, earn a mining reward), is determined by the network’s total hash rate ( i.e. , the total computational power devoted to solving a block), which is adjusted every 2,016 blocks (with a new block being added approximately every ten minutes). Therefore, as more miners join the network and the network’s global hash rate increases, its difficulty will increase. Conversely, if miners leave the network and its hash rate decreases, its difficulty will decrease. We have observed that when the market price for Bitcoin experiences a sustained increase (as it did across 2023), new miners are introduced onto the Bitcoin network, increasing its network hash rate, and network difficulty has increased as a result. Thus, despite increasing our hash rate by approximately 158.7% from September 30, 2023, to September 30, 2024, the halving in April 2024 and increased network difficulty following increased network hash rate across the periods resulted in an approximately 33.7% decrease in the number of Bitcoin we mined for the nine months ended September 30, 2024, as compared to the same period in 2023. ​ Accordingly, as market prices for Bitcoin increase and more miners and hash rate are drawn onto the Bitcoin network, network difficulty will continue to increase, meaning existing miners like us will need to increase their hash rate to maintain and improve their chances of earning a Bitcoin mining reward. To do this, we continually seek out new Bitcoin mining capacity, including through our acquisition and development of new Bitcoin mining facilities (such as the Corsicana Facility and our acquisition of Block Mining) and the electricity supply and distribution facilities to service them, as well as other strategic growth opportunities. Further, we have adopted new and improved technology to increase both our mining power and efficiency, including our industrial-scale adoption of immersion cooling and our strategic acquisitions of large quantities of the newest, most powerful and most efficient miners available. The Company has led the industry by focusing on a vertically-integrated business model since 2021. We continue to focus on building long-term stockholder value by taking strategic actions to further vertically-integrate our business at the current Rockdale Facility, developing the Corsicana Facility, and having acquired the Kentucky Facility. Management believes a focus on vertical integration will positively affect each of our business segments by providing increased capacity for our Bitcoin Mining operations, more opportunities for implementing our proprietary power strategy, and by capitalizing on supply chain efficiencies garnered through our Engineering segment. We continue to focus on deploying our efficient Bitcoin mining fleet, at scale, while realizing the benefits of being an owner and operator of our Bitcoin Mining facilities. ​ We anticipate the Bitcoin network will continue to see increased competition and that 2024 will be a period of consolidation in the Bitcoin mining industry. Further, given our relative position, liquidity, and absence of any significant long-term debt, we believe we are well positioned to benefit from such consolidation. We are continuously evaluating opportunities which we may decide to undertake as part of our strategic growth initiatives; however, we can offer no assurances that any strategic opportunities which we decide to undertake will be achieved on the schedule or within the budget we anticipate, if at all, and our business and financial results may change significantly as a result of such strategic growth. 34 Table of Contents ​ Bitcoin Mining We own and operate one of the largest Bitcoin Mining operations in North America. During the nine months ended September 30, 2024, we continued to deploy miners at our Rockdale Facility, continued development activities and commencement of deployment of miners at the Corsicana Facility, with the objective of increasing our operational efficiency and performance in the future, and acquired the Kentucky Facility. ​ As of September 30, 2024, our Bitcoin Mining business segment had a total deployed hash rate capacity of approximately 28.2 EH/s, as compared to 12.4 EH/s as of December 31, 2023, and 10.9 EH/s as of September 30, 2023, resulting in increases of 127.4% and 158.7%, respectively. We anticipate achieving a total self-mining hash rate capacity of approximately 34.9 EH/s by the end of 2024. ​ During the nine months ended September 30, 2024, we mined 3,312 Bitcoin, which represented a decrease of 1,684 Bitcoin from the 4,996 Bitcoin we mined during the nine months ended September 30, 2023. The decrease was primarily due to the increase in the Bitcoin network difficulty, which has more than doubled since January 2023, and the halving that occurred in April 2024, partially offset by higher Bitcoin prices and our increase in deployed hash rate. ​ As Bitcoin is a decentralized cryptocurrency, it is not required that Bitcoin be held by a custodian, and we may elect to self-custody. However, we believe our private keys relating to our Bitcoin are better safeguarded by the secure environment provided by custodians. Self-custodying poses an increased risk to our private keys and we may not have the same level of protection as custody providers who are well versed in industry best practices to protect digital assets from potential theft, loss, or destruction. Pursuant to the Digital Asset Custodial Agreement, dated as of November 1, 2023, between us and NYDIG Trust Company LLC (“NYDIG”) (as may be amended, modified or supplemented from time to time, the “NYDIG Custodial Agreement”), NYDIG, a well-known U.S.-based third-party digital asset-focused custodian, holds our Bitcoin in cold storage wallets in a digital asset account in our name. In exchange for its custodial services, NYDIG charges an annual fee equal to a percentage of our custodied Bitcoin based on the daily average value in U.S. dollars of the Bitcoin we custody with NYDIG. Our Bitcoin held in such digital asset accounts does not constitute “deposits” within the meaning of U.S. federal or state banking law and the digital asset accounts are not subject to Federal Deposit Insurance Corporation or Securities Investor Protection Corporation protections. The cold storage wallets in which our Bitcoin is held are all located in the United States. The NYDIG Custodial Agreement contains certain mutual indemnification provisions, including that NYDIG will indemnify us against direct claims for loss of custodied assets that arise directly from NYDIG’s or NYDIG’s nominees’ grossly negligent action, grossly negligent failure to act, bad faith or willful misconduct. For more information on the NYDIG Custodial Agreement, see the full text of the NYDIG Custodial Agreement included hereto as Exhibit 10.2, which qualifies the forgoing descriptions of the NYDIG Custodial Agreement in its entirety. We are also a party to a Digital Asset Execution Agreement with NYDIG Execution LLC (“NYDIG Execution”), pursuant to which NYDIG Execution executes or arranges transactions of our Bitcoin (“Orders”) as our agent. NYDIG Execution earns a commission on each trade determined by the net trade proceeds in U.S. dollars. NYDIG Execution does not charge us additional fees for principal trades. We deliver our Orders to NYDIG Execution via a designated security procedure, and each Order is affirmatively accepted by NYDIG Execution. While our Bitcoin may temporarily be processed through a NYDIG Execution customer account, NYDIG has covenanted that our assets will not be commingled with the assets of NYDIG Execution. NYDIG Execution is required to deposit any cash from the sale of our Bitcoin into our bank account at a U.S. depositary institution, less any applicable commissions. NYDIG Execution does not guarantee the value of our Bitcoin and is not responsible for any delay or failure to complete any Order caused by a digital asset network. If NYDIG Execution fails to (1) execute a properly executable Order and (2) give us notice of such failure, NYDIG Execution will only be liable for our actual damages. Our custodian and brokerage services relationships are non-exclusive, and we may freely change our Bitcoin custodian and brokerage relationships at any time. We continually monitor our Bitcoin assets held by third-party custodians, and we have unlimited audit rights with respect to such custodial accounts. The Company performs monthly reconciliations of our Bitcoin assets held by our custodian(s) and the records of our mining pool, and our independent auditors verify the location and quantity of our Bitcoin assets annually, as part of the year-end audit process of our financial statements and internal controls over financial reporting. The Company’s insurance providers do not have inspection rights associated with our Bitcoin assets held in cold storage. 35 Table of Contents The following table presents our key Bitcoin Mining metrics: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2024 ​ 2023 ​ 2024 2023 Hash rate, average operating (EH/s) (1) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Rockdale Facility ​ ​ 9.2 ​ ​ 5.0 ​ ​ 8.5 ​ ​ 6.5 Corsicana Facility ​ ​ 6.5 ​ ​ — ​ ​ 4.1 ​ ​ — Kentucky Facility ​ ​ 1.0 ​ ​ — ​ ​ 1.0 ​ ​ — Total hash rate, average operating ​ ​ 16.7 ​ ​ 5.0 ​ ​ 11.6 ​ ​ 6.5 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Hash rate, average deployed (EH/s) (1) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Rockdale Facility ​ ​ 14.8 ​ ​ 10.6 ​ ​ 13.3 ​ ​ 10.4 Corsicana Facility ​ ​ 11.9 ​ ​ — ​ ​ 6.3 ​ ​ — Kentucky Facility ​ ​ 1.3 ​ ​ — ​ ​ 1.2 ​ ​ — Total hash rate, average deployed ​ ​ 28.2 ​ ​ 10.6 ​ ​ 17.9 ​ ​ 10.4 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Developed power capacity (MW) (2) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Rockdale Facility ​ ​ 700 ​ ​ 700 ​ ​ 700 ​ ​ 700 Corsicana Facility ​ ​ 300 ​ ​ — ​ ​ 300 ​ ​ — Kentucky Facility ​ ​ 60 ​ ​ — ​ ​ 60 ​ ​ — Total power capacity ​ ​ 1,060 ​ ​ 700 ​ ​ 1,060 ​ ​ 700 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ All-in power cost (cents/kilowatt-hour) (3) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Rockdale Facility ​ ​ 2.8 ​ ​ (1.6) ​ ​ 3.1 ​ ​ 1.7 Corsicana Facility ​ ​ 3.8 ​ ​ — ​ ​ 4.9 ​ ​ — Kentucky Facility ​ ​ 3.8 ​ ​ — ​ ​ 3.8 ​ ​ — Total all-in power cost ​ ​ 3.1 ​ ​ (1.6) ​ ​ 3.2 ​ ​ 1.7 ​ (1) Hash rate, average deployed, represents the average total potential hash rate of all our deployed miners throughout the period, whereas hash rate, average operating, represents the average total hash rate our deployed miners provided throughout the period. The difference between deployed hash rate and operating hash rate is attributable to down time of all or some of miners for power curtailments, or repairs and maintenance of Bitcoin miners or supporting infrastructure. The difference between deployed and operating hash rate is a key measure in determining the efficiency of our Bitcoin Mining operations. ​ As of September 30, 2024, our Bitcoin Mining segment had a total hash rate, deployed of approximately 28.2 EH/s, as compared to 10.9 EH/s as of September 30, 2023. ​ (2) Developed power is the total amount of electricity our facilities can utilize for Bitcoin Mining. ​ (3) All-in power cost is the price we paid throughout the period for our power, net of power curtailments received. Power is overwhelmingly the largest marginal input cost in mining Bitcoin and a significant contributor to profitability. Miners with a low cost of power will also being able to profitability mine in a wider range of Bitcoin price. 36 Table of Contents The following table presents our cost to mine one Bitcoin ( amounts in thousands, except value of one Bitcoin amounts ): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2024 ​ 2023 ​ 2024 2023 Cost of power for self-mining operations ​ $ 41,864 ​ ​ $ 22,460 ​ ​ $ 96,326 ​ ​ $ 65,513 ​ Other direct cost of revenue for self-mining operations (1)(2) , excluding Bitcoin miner depreciation ​ 9,608 ​ ​ 1,989 ​ ​ 26,970 ​ ​ 4,482 ​ Cost of revenue for self-mining operations, excluding Bitcoin miner depreciation ​ 51,472 ​ ​ 24,449 ​ ​ 123,296 ​ ​ 69,995 ​ Less: power curtailment credits (3) ​ (12,417) ​ ​ (49,601) ​ ​ (31,445) ​ ​ (66,146) ​ Cost of revenue for self-mining operations, net of power curtailment credits, excluding Bitcoin miner depreciation ​ ​ 39,055 ​ ​ ​ (25,152) ​ ​ ​ 91,851 ​ ​ ​ 3,849 ​ Bitcoin miner depreciation (4) ​ ​ 44,303 ​ ​ ​ 55,549 ​ ​ ​ 93,120 ​ ​ ​ 164,457 ​ Cost of revenue for self-mining operations, net of power curtailment credits, including Bitcoin miner depreciation ​ $ 83,358 ​ ​ $ 30,397 ​ ​ $ 184,971 ​ ​ $ 168,306 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quantity of Bitcoin mined ​ 1,104 ​ ​ ​ 1,106 ​ ​ 3,312 ​ ​ 4,996 ​ Production value of one Bitcoin mined (5) ​ $ 61,133 ​ ​ $ 28,228 ​ ​ $ 58,771 ​ ​ $ 25,818 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cost to mine one Bitcoin, excluding Bitcoin miner depreciation ​ $ 35,376 ​ ​ $ (22,741) ​ ​ $ 27,733 ​ ​ $ 770 ​ Cost to mine one Bitcoin, excluding Bitcoin miner depreciation, as a % of production value of one Bitcoin mined ​ 57.9 % ​ ​ (80.6) % ​ 47.2 % ​ 3.0 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cost to mine one Bitcoin, including Bitcoin miner depreciation ​ $ 75,506 ​ ​ $ 27,484 ​ ​ $ 55,849 ​ ​ $ 33,688 ​ Cost to mine one Bitcoin, including Bitcoin miner depreciation, as a % of production value of one Bitcoin mined ​ ​ 123.5 % ​ ​ 97.4 % ​ ​ 95.0 % ​ ​ 130.5 % ​ (1) Other direct cost of revenue includes compensation, insurance, repairs, and ground lease rent and related property tax. ​ (2) Costs to finance the purchase of miners were zero in all periods presented as the miners were paid for with cash from the Company’s cash balance. The seller did not provide any financing nor did the Company borrow from a third-party to purchase the miners. ​ (3) Power curtailment credits are credited against our power invoices as a result of temporarily pausing our operations to participate in ERCOT’s Demand Response Service Programs. Our fixed-price power purchase contracts enable us to strategically curtail our mining operations and participate in these programs, which significantly lower our cost to mine Bitcoin. These credits are recognized in Power curtailment credits on our Condensed Consolidated Statements of Operations, outside of cost of revenue, but significantly reduce our overall cost to mine Bitcoin. ​ (4) The following table presents the future depreciation expense of all of our Bitcoin miners: ​ ​ ​ ​ ​ Remainder of 2024 ​ $ 55,905 2025 ​ 210,016 2026 ​ 135,270 2027 ​ 73,311 Total ​ $ 474,502 ​ (5) Computed as revenue recognized from Bitcoin mined divided by the quantity of Bitcoin mined during the same period. ​ During 2023, we entered into two purchase orders under the Master Agreement to acquire new immersion miners from MicroBT with a total hash rate of 25.6 EH/s, for a total purchase price of approximately $453.4 million, subject to downward price adjustment as provided by the Master Agreement. These new miners are primarily for use at our new Corsicana Facility, which commenced operations in April 2024. Delivery of these miners began in 2023, with all miners expected to be received by the end of 2024. The Master Agreement also provides us with four annual options to purchase additional miners, on the same or better terms as the second purchase order executed under the Master Agreement, for a total hash rate of approximately 75.0 EH/s, assuming exercise of all four annual purchase options. 37 Table of Contents During the nine months ended September 30, 2024, we executed an additional purchase order with MicroBT under the Master Agreement to acquire new air-cooled miners with a total hash rate of 5.9 EH/s, for a total purchase price of approximately $96.7 million. This purchase order is in addition to the four purchase options remaining under the Master Agreement. Delivery of these miners occurred in the third quarter of 2024, with deployment commencing upon delivery. For the three and nine months ended September 30, 2024, Bitcoin Mining revenue was approximately $67.5 million and $194.7 million, respectively. ​ Data Center Hosting In 2023, we made the decision to stop pursuing new hosting contracts and end our legacy contracts, to focus on our self-mining efforts. During the nine months ended September 30, 2024, all agreements with Data Center Hosting customers were terminated, and we have no plans to offer data center hosting services to new customers. For the three and nine months ended September 30, 2024, we no longer report Data Center Hosting as a separate reportable segment. Engineering Our Engineering business segment designs and manufacturers power distribution equipment and custom engineered electrical products that provide us with the ability to vertically-integrate many of the critical electrical components and engineering services necessary for our Corsicana Facility development and Rockdale Facility expansions and to reduce our execution and counter-party risk in ongoing and future expansion projects. Engineering and other specialized talent employed in our Engineering business segment also allows us to continue to explore new methods to optimize and develop a best-in-class Bitcoin Mining operation and has been instrumental in the development of our industrial-scale immersion-cooled Bitcoin mining hardware. Our Engineering business segment also provides electricity distribution product design, manufacturing, and installation services primarily focused on large-scale commercial and governmental customers and serves a broad scope of clients across a wide range of markets including data center, power generation, utility, water, industrial, and alternative energy. Products are custom built to client and industry specifications. Engineering revenue is derived from the sale of custom products built to customers’ specifications under fixed-price contracts with one identified performance obligation. Engineering revenue is recognized over time as performance creates or enhances an asset with no alternative use, and for which we have an enforceable right to receive compensation as defined under the contract. For the three and nine months ended September 30, 2024, Engineering revenue was approximately $12.6 million and $26.9 million. respectively. Power Strategy Long-term power contracts form the basis of our power strategy. We utilize our 345 MW PPA in three ways: Manual Curtailment We power down operations and return power back to the utility when market prices for electricity provide the potential for us to receive more power curtailment credits than the Bitcoin Mining revenues we would have generated had we not curtailed our mining operations. We receive power credits for the difference in the market power price and our fixed power price, which provides us the ability to maximize our overall profitability between Bitcoin Mining and supporting the grid by not drawing power from the grid when electricity is most scarce. 38 Table of Contents ERCOT Ancillary Services We competitively bid to sell ERCOT the option to control our electrical load during certain hours. ERCOT compensates us in the form of Demand Response Credits, which are received whether or not ERCOT calls on us to power down. ERCOT’s 4CP Program We voluntarily power down operations during times of peak demand in summer months. Participation provides us substantial savings on transmission costs in the subsequent year’s power bills, reducing our overall power costs. The following table presents our power curtailment credits: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2024 2023 2024 2023 Manual curtailment power credits ​ $ 11,926 ​ $ 41,127 ​ $ 24,923 ​ $ 51,340 Demand response power credits ​ ​ 491 ​ ​ 8,474 ​ ​ 6,522 ​ ​ 14,806 Total power curtailment credits ​ $ 12,417 ​ $ 49,601 ​ $ 31,445 ​ $ 66,146 ​ The following graph presents the primary decision points that guide our decision to curtail power usage or power down our mining operations, and when we might resume mining operations: ​ ​ ERCOT Grid Curtailment The Public Utility Commission of Texas (“PUCT”), ERCOT, and Oncor Electric Delivery Company (“Oncor”) collectively oversee the regulatory, administrative, and delivery aspects of our power supply in Texas. In recent years, regulatory scrutiny on Bitcoin mining facilities and their energy consumption has intensified as the practice has become more widespread. ​ As the grid operator, ERCOT is responsible for monitoring and testing market participants, including our Bitcoin mining data centers in Rockdale and Corsicana, to evaluate their impact on grid reliability. During this process, ERCOT may issue curtailment notices to reduce the power usage at our Texas operations. We are periodically tested and monitored, and have experienced curtailment of power based on instructions we receive from Oncor and ERCOT. Due to the uncertainties regarding the duration or extent of power curtailments and testing procedures, we are currently unable to reasonably estimate any potential impacts to our business. If we 39 Table of Contents cannot secure adequate access to electrical power, we may be forced to reduce or shut down our operations, which would have a material adverse effect on our business, prospects, financial condition, and operating results. ​ Global Logistics Global supply logistics have caused delays across all channels of distribution. We have also experienced delays in our Engineering segment’s manufacturing and delivery schedule, and in our infrastructure development schedules, resulting from constraints on the globalized supply chains for miners, electricity distribution equipment and construction materials. Through the date of this Quarterly Report, we have been able to effectively and efficiently mitigate delivery delays to avoid materially impacting our miner deployment schedule; however, we cannot guarantee that we will be able to continue to mitigate any such delivery delays in the future. ​ Additionally, the development of the Corsicana Facility requires large quantities of construction materials, specialized electricity distribution equipment, and other component parts that are in high demand and can be difficult to source. To help mitigate the impacts of global supply chain constraints and increasing demand for these goods, including any inflationary pricing concerns that may result, we procured all the required components and materials for development of the first 400 MW phase of the Corsicana Facility, and we have procured and already hold many of the components and materials required for development of the next 600 MW phase of our development of the Corsicana Facility, as well as replacement components and parts for our existing systems, to help shorten the impact of potential damage to installed equipment. ​ We continue to monitor developments in the global supply chain and assess their potential impact on our expansion plans. ​ Summary of Riot’s Bitcoin Mining Results The following tables present additional information about our own Bitcoin Mining activities, including Bitcoin production and sales of the Bitcoin mined: ​ ​ ​ ​ ​ ​ ​ ​ ​ Quantity ​ Amounts Balance as of January 1, 2024 7,362 ​ $ 311,178 Revenue recognized from Bitcoin mined 3,312 ​ 194,651 Change in Bitcoin receivable 6 ​ (93) Proceeds from sale of Bitcoin (212) ​ (9,518) Exchange of Bitcoin for employee compensation (41) ​ (2,099) Change in fair value of Bitcoin — ​ 166,231 Balance as of September 30, 2024 10,427 ​ $ 660,350 ​ ​ ​ ​ ​ ​ ​ ​ ​ Quantity ​ Amounts Balance as of January 1, 2023 6,974 ​ $ 115,415 Revenue recognized from Bitcoin mined 4,996 ​ 128,987 Proceeds from sale of Bitcoin (4,615) ​ (118,833) Exchange of Bitcoin for employee compensation (28) ​ (696) Change in fair value of Bitcoin — ​ 72,733 Balance as of September 30, 2023 7,327 ​ $ 197,606 ​ Results of Operations Comparative Results for the three months ended September 30, 2024, and 2023: Revenue Total revenue for the three months ended September 30, 2024 and 2023, was $84.8 million and $51.9 million, respectively. Total revenue consists of our Bitcoin Mining revenue, Engineering revenue, and Other revenue. Other revenue consists almost entirely of residual activity related to our ceased Data Center Hosting segment. For the three months ended September 30, 2024 and 2023, Bitcoin Mining revenue was $67.5 million and $31.2 million, respectively. The increase of $36.3 million was primarily due to higher Bitcoin prices in the 2024 period, which averaged $61,133 per coin, as compared to $28,228 per coin for the 2023 period. Despite the substantial increase in the Bitcoin network difficulty and the April 2024 halving, Bitcoin production was consistent for each of the periods presented. 40 Table of Contents For the three months ended September 30, 2024 and 2023, Engineering revenue was $12.6 million and $15.5 million, respectively. The decrease of $2.9 million was primarily attributable to supply chain constraints resulting in decreased receipts of materials, delaying the completion of certain custom products, and, therefore, the recognition of revenue. Our custom electrical products such as switchgear and power distribution centers are used as important components in data center development and in power generation and distribution facilities, and there has been increased demand for these products due to the continued increase in data center construction by developers, as well as the continually increasing worldwide demand for power. Costs and expenses For the three months ended September 30, 2024 and 2023, Cost of revenue for Bitcoin Mining consisted of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ September 30, ​ 2024 2023 Power ​ $ 41,864 ​ $ 22,460 Compensation ​ ​ 3,786 ​ ​ — Insurance on miners ​ ​ 1,871 ​ ​ 803 Ground rent and related water and property tax ​ ​ 1,565 ​ ​ — Other (1) ​ ​ 2,386 ​ ​ 1,186 Total Bitcoin Mining cost of revenue ​ $ 51,472 ​ $ 24,449 ​ (1) All amounts included within Other are individually insignificant. ​ The increase of approximately $27.0 million of Cost of revenue for Bitcoin Mining was primarily due to the increase in Bitcoin mining capacity at the Rockdale Facility and commencement of Bitcoin mining activities at the Corsicana Facility, both of which require additional headcount and direct costs necessary to maintain and support our expanded Bitcoin mining operations, as well as the absorption of other costs previously included in our former Data Center Hosting segment. Cost of revenue for Bitcoin Mining excludes depreciation and amortization, which are stated separately on our Condensed Consolidated Statements of Operations. Cost of revenue for Engineering for the three months ended September 30, 2024 and 2023, was $13.5 million and $13.2 million, respectively, an increase of approximately $0.3 million. The costs consisted primarily of direct materials and labor, as well as indirect manufacturing costs, all of which increased slightly as supply chain constraints began to ease during the three months ended September 30, 2024. ​ Selling, general and administrative expenses for the three months ended September 30, 2024 and 2023, were $66.9 million and $29.1 million, respectively, an increase of approximately $37.8 million. Selling, general and administrative expenses consist of stock-based compensation, legal and professional fees, and other personnel and related costs. The increase was primarily due to increases in stock compensation expenses of $17.0 million, which was primarily due to new grants under our long-term incentive program that was implemented in July 2023, compensation expenses of $7.6 million as a result of hiring additional employees to support our ongoing growth, increased legal and professional fees of $6.8 million primarily related to ongoing litigation and public company compliance, and $5.3 million for additional insurance and other costs primarily attributable to ongoing growth. Depreciation and amortization for the three months ended September 30, 2024 and 2023, was $60.0 million and $64.6 million, respectively, a decrease of approximately $4.6 million. The decrease was primarily due to the change in the estimated lives of our Bitcoin miners from 2 years to 3 years, partially offset by increased depreciation from the Corsicana Facility coming online in April 2024 and additional miners being deployed. The change in fair value of Bitcoin for the three months ended September 30, 2024 and 2023, were gains of $8.6 million and losses of $25.3 million, respectively, and were recognized to adjust the fair value of our Bitcoin held at the end of each period. The change in fair value of our derivative asset for the three months ended September 30, 2024 and 2023, were losses of $24.3 million and gains of $3.9 million, respectively, and was recorded to adjust the fair value of our PPA, which was classified as a derivative asset and measured at fair value. The changes in fair value were due to changes in future power prices over the applicable period. The loss incurred during the three months ended September 30, 2024, was primarily attributable to the average of the forward prices utilized in the discounted cash flow estimation models decreasing from $51.13 per mWh as of June 30, 2024 to $48.80 per mWh as of September 30, 2024. The gain recognized during the three months ended September 30, 2023, was primarily attributable 41 Table of Contents to the average of the forward prices increasing from $44.12 per mWh as of June 30, 2023 to $45.55 per mWh as of September 30, 2023. Power curtailment credits for the three months ended September 30, 2024 and 2023, were $12.4 million and $49.6 million, respectively, and represent sales of unused power under our PPA and participation in ancillary services under ERCOT Demand Response Services Programs. The amount of these credits varies from period to period depending on various factors impacting the supply of power to, and the demand for power on, the ERCOT grid, such as weather and global fuel costs. Other income (expense) For the three months ended September 30, 2024 and 2023, total other income (expense) was ($32.8) million and $2.3 million, respectively. The change was primarily attributable to unrealized losses on marketable securities of $38.1 million, partially offset by higher interest income earned as a result of higher cash balances and increased interest rates. Comparative Results for the nine months ended September 30, 2024 and 2023: Revenue Total revenue for the nine months ended September 30, 2024 and 2023, was $234.1 million and $201.9 million, respectively. Total revenue consists of our Bitcoin Mining revenue, Engineering revenue, and Other revenue. For the nine months ended September 30, 2024 and 2023, Bitcoin Mining revenue was $194.7 million, and $129.0 million, respectively. The increase of $65.7 million was primarily due to higher Bitcoin prices in the 2024 period, which averaged $58,771 per coin, as compared to $25,818 per coin for the 2023 period, which was partially offset by a decrease of 1,684 Bitcoin mined in the 2024 period as compared to the 2023 period, primarily due to the substantial increase in the Bitcoin network difficulty and April 2024 halving. For the nine months ended September 30, 2024 and 2023, Engineering revenue was $26.9 million and $51.0 million, respectively. The decrease of $24.1 million was primarily attributable to supply chain constraints resulting in decreased receipts of materials, delaying the completion of certain custom products, and, therefore, the recognition of revenue. Our custom electrical products such as switchgear and power distribution centers are used as important components in data center development and in power generation and distribution facilities, and there has been increased demand for these products due to the continued increase in data center construction by developers, as well as the continually increasing worldwide demand for power. Costs and expenses For the nine months ended September 30, 2024 and 2023, Cost of revenue for Bitcoin Mining consisted of the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Ended ​ ​ September 30, ​ 2024 2023 Power ​ $ 96,326 ​ $ 65,513 Compensation ​ ​ 9,251 ​ ​ — Insurance on miners ​ ​ 5,246 ​ ​ 2,911 Ground rent and related water and property tax ​ ​ 4,171 ​ ​ — Other (1) ​ ​ 8,302 ​ ​ 1,571 Total Bitcoin Mining cost of revenue ​ $ 123,296 ​ $ 69,995 ​ (1) All amounts included within Other are individually not material. ​ The increase of approximately $53.3 million was primarily due to the increase in Bitcoin mining capacity at the Rockdale Facility, and commencement of Bitcoin mining activities at the Corsicana Facility, both of which require more headcount and direct costs necessary to maintain and support our expanded Bitcoin mining operations, as well as the absorption of other costs previously included in our Data Center Hosting segment. Cost of revenue for Bitcoin Mining excludes depreciation and amortization, which are stated separately on our Condensed Consolidated Statements of Operations. ​ 42 Table of Contents Cost of revenue for Engineering for the nine months ended September 30, 2024 and 2023, was $27.8 million and $46.9 million, respectively, a decrease of approximately $19.1 million. The costs consisted primarily of direct materials and labor, as well as indirect manufacturing costs. Consistent with the causes of decreased Engineering revenue noted above, the decrease was primarily due to decreased receipts of materials resulting from increased competition for direct materials due to supply chain constraints. ​ Selling, general and administrative expenses for the nine months ended September 30, 2024 and 2023, were $185.8 million and $61.6 million, respectively, an increase of approximately $124.2 million. Selling, general and administrative expenses consist of stock-based compensation, legal and professional fees, and other personnel and related costs. The increase was primarily due to increases in stock compensation expenses of $80.3 million, which was primarily due to new grants under our long-term incentive program, compensation expenses of $15.8 million as a result of hiring additional employees to support our ongoing growth, increased legal and professional fees of $12.7 million primarily related to ongoing litigation and public company compliance, and $15.4 million for additional insurance and other costs primarily attributable to ongoing growth. Depreciation and amortization for the nine months ended September 30, 2024 and 2023, was $129.7 million and $190.1 million, respectively, a decrease of approximately $60.4 million. The decrease was primarily due to the change in the estimated lives of our Bitcoin miners from 2 years to 3 years, partially offset by increased depreciation from the Corsicana Facility coming online in April 2024 and additional miners being deployed. The change in fair value of Bitcoin for the nine months ended September 30, 2024 and 2023, were gains of $166.2 million and $72.7 million, respectively, and were recognized to adjust the fair value of our Bitcoin held at the end of each period. The change in fair value of our derivative asset for the nine months ended September 30, 2024 and 2023, were gains of $23.4 million and $11.3 million, respectively, and was recorded to adjust the fair value of our PPA, which was classified as a derivative asset and measured at fair value. The changes in fair value were due to changes in future power prices over the applicable period. The gain incurred during the nine months ended September 30, 2024, was primarily attributable to the average of the forward prices utilized in the discounted cash flow estimation models increasing from $45.15 per mWh as of December 31, 2023 to $48.80 per mWh as of September 30, 2024. The gain recognized during the three months ended September 30, 2023, was primarily attributable to the average of the forward prices increasing from $43.59 per mWh as of December 31, 2022 to $45.55 per mWh as of September 30, 2023. Power curtailment credits for the nine months ended September 30, 2024 and 2023, were $31.4 million and $66.1 million, respectively, and represent sales of unused power under our PPA and participation in ancillary services under ERCOT Demand Response Services Programs. The amount of these credits varies from period to period depending on various factors impacting the supply of power to, and the demand for power on, the ERCOT grid, such as weather and global fuel costs. Casualty-related charges (recoveries), net, were ($2.5) million and $1.5 million for the nine months ended September 30, 2024 and 2023, respectively. In December 2022, the Rockdale Facility was damaged during severe winter storms in Texas, resulting in casualty-related charges being recognized in 2023. The income recognized during the nine months ended September 30, 2024, was the result of cash recoveries from insurance claims related to the December 2022 winter storms. Other income (expense) For the nine months ended September 30, 2024 and 2023, total other income (expense) was $7.6 million and $3.4 million, respectively. The increase was primarily attributable to higher interest income earned as a result of higher cash balances and increased interest rates, partially offset by unrealized losses on marketable securities of $13.6 million. Non-GAAP Measures In addition to financial measures presented under generally accepted accounting principles in the United States (“GAAP”), we consistently evaluate our use of and calculation of non-GAAP performance measures such as “Adjusted EBITDA.” EBITDA is computed as net income before interest, taxes, depreciation, and amortization. Adjusted EBITDA is a performance measure defined as EBITDA adjusted to eliminate the effects of certain non-cash and/or non-recurring items that do not reflect our ongoing strategic business operations, which management believes results in a performance measurement that represents a key indicator of our core business operations of Bitcoin mining. The adjustments include fair value adjustments such as derivative power contract adjustments, equity securities value changes, and non-cash stock-based compensation expense, in addition to financing and legacy business income and expense items. 43 Table of Contents We believe Adjusted EBITDA can be an important performance measure because it allows management, investors, and our board of directors to evaluate and compare our operating results, including our return on capital and operating efficiencies, from period-to-period by making such adjustments. Additionally, Adjusted EBITDA is used as a performance metric for share-based compensation. Adjusted EBITDA is provided in addition to, and should not be considered to be a substitute for, or superior to, net income, the most comparable measure under GAAP to Adjusted EBITDA. Further, Adjusted EBITDA should not be considered as an alternative to revenue growth, net income, diluted net income per share or any other performance measure derived in accordance with GAAP, or as an alternative to cash flow from operating activities as a measure of our liquidity. Adjusted EBITDA has limitations as an analytical tool, and you should not consider this performance measure either in isolation or as a substitute for analyzing our results as reported under GAAP. ​ The following table reconciles Adjusted EBITDA to Net income (loss) , the most comparable GAAP performance measure: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2024 2023 2024 2023 Net income (loss) ​ $ (154,362) ​ $ (80,040) ​ $ (27,034) ​ $ (88,914) Interest (income) expense ​ (5,175) ​ (2,318) ​ (21,132) ​ (3,331) Income tax expense (benefit) ​ 32 ​ (157) ​ 65 ​ (5,014) Depreciation and amortization ​ 60,000 ​ 64,569 ​ 129,669 ​ 190,071 EBITDA ​ (99,505) ​ (17,946) ​ 81,568 ​ 92,812 ​ ​ ​ ​ ​ Adjustments: ​ ​ ​ ​ Stock-based compensation expense ​ 30,567 ​ 13,519 ​ 94,702 ​ 14,652 Acquisition-related costs ​ 3,079 ​ — ​ 3,079 ​ — Change in fair value of derivative asset ​ 24,318 ​ (3,943) ​ (23,398) ​ (11,274) Unrealized loss (gain) on equity method investment - marketable securities ​ ​ 38,082 ​ ​ — ​ ​ 13,620 ​ ​ — Loss (gain) on sale/exchange of equipment ​ — ​ 5,306 ​ 68 ​ 5,336 Casualty-related charges (recoveries), net ​ ​ — ​ ​ — ​ ​ (2,487) ​ ​ 1,526 Other (income) expense ​ (90) ​ (31) ​ (131) ​ (96) License fees ​ (24) ​ (24) ​ (48) ​ (48) Adjusted EBITDA ​ $ (3,573) ​ $ (3,119) ​ $ 166,973 ​ $ 102,908 ​ LIQUIDITY AND CAPITAL RESOURCES As of September 30, 2024, we had net working capital of approximately $590.6 million, which included cash and cash equivalents of $355.7 million and marketable securities of $190.1 million. We reported a net loss of $27.0 million during the nine months ended September 30, 2024, which included $143.6 million in non-cash net gains, primarily consisting of revenue recognized from Bitcoin mined of $194.7 million, the change in fair value of Bitcoin of $166.2 million, and the change in fair value of the derivative asset of $23.4 million, partially offset by depreciation and amortization of $129.7 million, stock-based compensation of $94.7 million, and the unrealized loss on marketable securities of $13.6 million. During the nine months ended September 30, 2024, we sold 212 Bitcoin for proceeds of approximately $9.5 million. Subsequent to those sales, we made the strategic decision to temporarily halt the sale of all our Bitcoin production and instead, increase our Bitcoin holdings. Contractual Commitments (Miners and Related Equipment) Through September 30, 2024, we have paid approximately $448.5 million in total deposits and payments to MicroBT for the purchase of miners. The remaining commitment of approximately $112.5 million is due in installments through approximately December 2024 based on the estimated miner delivery schedule. Through September 30, 2024, we paid $72.4 million in total deposits and payments for the purchase of immersion cooling systems. The remaining commitment of approximately $7.7 million is due upon commissioning of the systems, which is expected to occur in the fourth quarter of 2024. 44 Table of Contents Development of the Corsicana Facility In 2022, we announced our planned development of the Corsicana Facility, our second large-scale Bitcoin mining facility located on a 265-acre site in Navarro County, Texas. The Corsicana Facility is expected, upon completion, to have 1.0 GW of developed capacity for Bitcoin mining, with an additional 200 MW of electrical capacity available for development, at our discretion, which is securely supplied with power by a substation being developed for us on the premises that will be interconnected with the nearby Navarro Switch. The strategic decision to locate the Corsicana Facility next to the Navarro Switch was made to limit electricity lost in transmission and maximize the efficiency of our substation’s power distribution facilities. The initial phase of the development of the Corsicana Facility involved the construction of a 400 MW substation and an equal amount of immersion-cooled Bitcoin mining infrastructure spread across multiple buildings, as well as construction of various utilities, offices, warehouses, and infrastructure to support the facility’s operations. Our Bitcoin mining operations commenced in April 2024, following commissioning of the substation. As of September 30, 2024, Corsicana deployed 300 MW of Bitcoin mining infrastructure comprised of three 100 MW buildings, Buildings A1, A2 and B1, which were completed, and the fourth 100 MW building, Building B2, was under construction. Development of Building B2 continues on schedule and is expected to be completed during the fourth quarter of 2024. ​ We estimate that the total cost of the first 400 MW phase of the development will be approximately $381.4 million. Through September 30, 2024, we had incurred costs of approximately $377.6 million related to the development of the Corsicana Facility, including $10.1 million for land. We expect to incur the remaining $3.8 million during the remainder of 2024. Revenue from Operations Bitcoin Mining We expect to generate ongoing revenue from Bitcoin rewards from our Bitcoin Mining operations and our ability to liquidate Bitcoin rewards at future values will be regularly evaluated to generate cash for operations. Generating Bitcoin rewards which exceed our production and overhead costs will determine our ability to report profit margins related to such Bitcoin Mining operations, although accounting for our reported profitability is significantly complex. Furthermore, regardless of our ability to generate proceeds from the sale of our Bitcoin produced from our Bitcoin Mining business, we may elect to continue our strategy of holding the Bitcoin rewards we earn from our Bitcoin Mining operations, and we may need to raise additional capital in the form of equity or debt to fund our operations and pursue our business strategy. The ability to raise funds through the sale of equity, debt financings, or the sale of Bitcoin to maintain our operations is subject to many risks and uncertainties and, even if we were successful, future equity issuances or convertible debt offerings could result in dilution to our existing stockholders, and any future debt or debt securities may contain covenants that limit our operations or ability to enter into certain transactions. Our ability to realize revenue through Bitcoin production and successfully convert Bitcoin into cash or fund overhead with Bitcoin is subject to a number of risks, including regulatory, financial and business risks, many of which are beyond our control. Additionally, we have observed significant historical volatility in the market price of Bitcoin and, as such, future prices cannot be predicted. Engineering Substantially all Engineering revenue is derived from the sale of custom products built to customers’ specifications under fixed-price contracts. Revenue is recognized over time as performance creates or enhances an asset with no alternative use, and for which we have an enforceable right to receive compensation as defined under the contract. The length of time required to complete a custom product varies but is typically between four and 12 weeks. Customers are typically required to make periodic progress payments based on contractually agreed-upon milestones. If we are unable to generate sufficient revenue from our Bitcoin Mining and Engineering operations when needed or secure additional sources of funding, it may be necessary to significantly reduce our current rate of spending or explore other strategic alternatives. Operating Activities For the nine months ended September 30, 2024 and 2023, net cash used in operating activities was $156.7 million and $12.0 million, respectively. The increase in cash used was primarily attributable to $109.3 million reduction in proceeds from the sale of Bitcoin due to our ceasing of sales of Bitcoin early in 2024, increased power costs of $30.7 million, and a $43.9 million increase in selling, 45 Table of Contents general, and administrative costs, excluding stock-based compensation, both of which were primarily driven by our increased mining capacity and headcount, combined with other general operating costs such as insurance and information technology projects to support our growth. Investing Activities For the nine months ended September 30, 2024 and 2023, net cash used in investing activities was $726.2 million and $232.4 million, respectively, which was primarily attributable to purchases and deposits paid for miners and purchases of property and equipment for our ongoing expansions, as we continue towards our anticipated 34.9 EH/s of total self-mining hash rate capacity by the end of 2024. We completed our expansion of the Rockdale Facility during the year ended December 31, 2023, and continue to develop the Corsicana Facility, which commenced self-mining operations during the second quarter of 2024. We anticipate incurring additional costs related to the first phase of the Corsicana Facility of approximately $3.8 million during the remainder of 2024. During the nine months ended September 30, 2024, we paid $448.5 million in deposits and payments for the purchase of miners, and anticipate additional payments of $112.5 million to be made in 2024. During 2024, we also purchased 90.1 million shares of Bitfarms common stock for $203.8 million and acquired Block Mining for $7.2 million in cash (net of cash acquired). Financing Activities For the nine months ended September 30, 2024 and 2023, net cash provided by financing activities was $714.1 million and $304.1 million, respectively, consisting primarily of proceeds from our ATM Offerings of $746.4 million and $324.6 million, respectively. We have approximately $6.3 million in long-term debt, primarily consisting of debt acquired as part of the Block Mining acquisition, and have primarily financed our strategic growth through proceeds from our ATM Offerings and issuances of our common stock. It is reasonably likely that we will continue to finance our ongoing growth with proceeds from current and future ATM Offerings. Critical Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and accompanying notes. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results inevitably will differ from those estimates, and such differences may be material to our financial statements. Business combinations Accounting for business combinations requires management to make significant estimates and assumptions, especially at the acquisition date, including estimates for property and equipment and contingent consideration, where applicable. Although we believe our assumptions and estimates have been reasonable and appropriate, they are based in part on historical experience and information obtained from management of the acquired companies and are inherently uncertain. Estimates used in determining the value of property and equipment included the estimated replacement costs, which included replacement cost new, remaining life, and effective age. Estimates used in determining the value of the contingent consideration included the timing and probability of achieving milestones and a discount rate. PPA Valuation Our PPA is accounted for as a derivative, the valuation of which is based on significant unobservable inputs utilized in the valuation, which include discounted cash flow estimation models containing quoted commodity exchange spot and forward prices and are adjusted for basis spreads for load zone-to-hub differentials through the term of the PPA. Significant judgement and estimation is required when creating the discounted cash flow estimation models. Should our discounted cash flow estimation models change significantly, potentially material changes to the fair value of the derivative asset may result, which could have a material impact on our financial statements. See Note 9. Power Supply Agreements in the Notes for a discussion of the unobservable inputs and their impact on the valuation. Long-Lived Assets Long-lived assets are stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets. Judgment is necessary in estimating the Company’s various assets’ useful lives. This includes evaluating the Company’s own usage experience with its currently owned assets, the quality of materials used in construction-related projects, and for its miners, the rate 46 Table of Contents of technological advancement and market-related factors such as the price of Bitcoin and the Bitcoin network hash rate, which impact the value of the miners. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, which is determined based on a comparison of the carrying amount of an asset to undiscounted future cash flows expected to be generated by the asset. Significant judgment is used when estimating future cash flows, particularly the price of Bitcoin and the Bitcoin network hash rate. If such assets are considered impaired, an impairment is recognized based on the amount by which the carrying amount exceeds the estimated fair value of the assets. Should our estimates of useful lives, undiscounted future cash flows, or asset fair values change, additional and potentially material impairments may be required, which could have a material impact on our reported financial results. Stock-Based Compensation Stock-based compensation expense related to share-based payment awards is recognized at the grant date of the award and is estimated based on the fair market value of the Company’s common stock at the time of the grant. Compensation cost for performance-based, share-based payment awards is recognized over the performance period when achievement of the milestones and targets becomes probable. The Company uses significant judgment in determining the likelihood of meeting milestones and market conditions. Inputs into valuation models such as Monte Carlo simulations include both the Company’s and the Russell 3000’s historical and expected annual volatilities, and depending on the inputs selected, the Company could calculate significantly different estimated grant date fair values, materially impacting the valuation of our stock-based awards and the stock-based compensation expense we recognize in future periods.
