Forward-looking statements can be identified by the use of words such as “expects,” “plans,” “will,” “forecasts,” “projects,” “intends,” “estimates,” and other words of similar meaning. One can identify them by the fact that they do not relate strictly to historical or current facts. These statements are likely to address our growth strategy, financial results and product and development programs. One must carefully consider any such statement and should understand that many factors could cause actual results to differ from our forward-looking statements. These factors may include inaccurate assumptions and a broad variety of other risks and uncertainties, including some that are known and some that are not. No forward-looking statement can be guaranteed, and actual future results may vary materially.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">These statements are only predictions and involve known and unknown risks, uncertainties and other factors, including the risks in the section entitled “Risk Factors” and the risks set out below, any of which may cause our or our industry’s actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

Marathon also acquires bitcoin when our cash, cash equivalents and short-term investments exceed current working capital requirements, and we may from time to time, subject to favorable market conditions, issue debt or equity securities to raise capital to use the proceeds to purchase bitcoin. To Marathon, the strategy is to hold bitcoin as a long term investment rather than engaging in regular trading of bitcoin or to hedge or otherwise enter into derivative contracts with respect to our bitcoin holdings, though we may sell bitcoin in future periods as needed to generate cash for treasury management and other general corporate purposes. Holding bitcoin is a strategy to act as a store of value, supported by a robust and public open source architecture, that is not linked to any country’s monetary policy and can therefore serve as a hedge against inflation. We are of the firm belief that bitcoin offers additional opportunity for appreciation in value with increasing adoption due to its limited supply. We may also explore opportunities to become involved in businesses ancillary to our bitcoin mining business as favorable market conditions and opportunities arise.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">We were incorporated in the State of Nevada on February 23, 2010 under the name Verve Ventures, Inc.

To mitigate these issues in the future, system upgrades will be performed on the power generating station beginning in November 2021 and continuing into 2022. Each phase of this maintenance will require the plant, and therefore the Company’s mining operations in Hardin, MT, to be offline for approximately three to five days. The upgrades are intended to improve the power generating station’s efficacy and efficiency, increase safety, mitigate the potential for unexpected downtime in the future, and ultimately improve the Company’s ability to effectively mine bitcoin.

This network hosts a public transaction ledger, known as the bitcoin blockchain, on which bitcoin holdings and transactions in bitcoin are recorded. Balances of bitcoin are stored in individual “wallet” functions, which associate network public addresses with a “private key” that controls the transfer of bitcoin. The bitcoin blockchain can be updated without any single entity owning or operating the network. New bitcoin is created and allocated by the protocol that governs bitcoin through a “mining” process that rewards users that verify transactions in the bitcoin blockchain. The bitcoin protocol limits the total issuance of bitcoin over time to 21 million.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Bitcoin can be used to pay for goods and services, or it can be converted to fiat currencies, such as the U.S. dollar, at rates of exchange determined by market forces on bitcoin trading platforms, which operate 24-hours-a-day, 7-days-a-week and are not regulated in as comprehensive a manner as traditional securities exchanges. As a result, trading on these markets is likely more subject to manipulation than on securities markets regulated by the SEC, and pricing on these markets is likely affected by such manipulative activity. In addition to these platforms, over-the-counter markets and derivatives markets for bitcoin also exist; however, these markets are still maturing and many are unregulated.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Bitcoin exists entirely in electronic form, as virtually irreversible public transaction ledger entries on the blockchain, and transactions in bitcoin are recorded and authenticated not by a central repository, but by a decentralized peer-to-peer network. This decentralization avoids certain threats common to centralized computer networks, such as denial of service attacks, and reduces the dependency of the bitcoin network on any single system. While the bitcoin network as a whole is decentralized, the private keys used to access bitcoin balances are not widely distributed and are held on hardware (which can be physically controlled by the holder or by a third party such as a custodian) or via software programs on third-party servers and loss of such private keys results in an inability to access, and effective loss of, the corresponding bitcoin. Consequently, bitcoin holdings are susceptible to all of the risks inherent in holding any electronic data, such as power failure, data corruption, security breach, communication failure, and user error, among others. These risks, in turn, make bitcoin subject to theft, destruction, or loss of value from hackers, corruption, or technology-specific factors such as viruses that do not affect conventional fiat currency. In addition, the bitcoin network relies on open source developers to maintain and improve the bitcoin protocol. Accordingly, bitcoin may be subject to protocol design changes, governance disputes such as “forked” protocols, competing protocols, and other open source-specific risks that do not affect conventional proprietary software.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <!-- Field: Page; Sequence: 12; Value: 2 --> <div style="border-bottom: Black 1.5pt solid; margin-bottom: 6pt"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="text-align: center; width: 100%"><!-- Field: Sequence; Type: Arabic; Name: PageNo -->12<!-- Field: /Sequence --></td></tr></table></div> <div style="break-before: page; margin-top: 6pt"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="text-align: center; width: 100%"> </td></tr></table></div> <!-- Field: /Page --> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Distributed blockchain technology is a decentralized and encrypted ledger that is designed to offer a secure, efficient, verifiable, and permanent way of storing records and other information without the need for intermediaries. Cryptocurrencies serve multiple purposes. They can serve as a medium of exchange, store of value or unit of account. Examples of cryptocurrencies include: bitcoin, bitcoin cash, and litecoin. Blockchain technologies are being evaluated for a multitude of industries due to the belief in their ability to have a significant impact in many areas of business, finance, information management, and governance.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Cryptocurrencies are decentralized currencies that enable near instantaneous transfers. Transactions occur via an open source, cryptographic protocol platform which uses peer-to-peer technology to operate with no central authority. The online network hosts the public transaction ledger, known as the blockchain, and each cryptocurrency is associated with a source code that comprises the basis for the cryptographic and algorithmic protocols governing the blockchain. In a cryptocurrency network, every peer has its own copy of the blockchain, which contains records of every historical transaction - effectively containing records of all account balances. Each account is identified solely by its unique public key (making it effectively anonymous) and is secured with its associated private key (kept secret, like a password). The combination of private and public cryptographic keys constitutes a secure digital identity in the form of a digital signature, providing strong control of ownership.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; text-indent: 0.55in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">No single entity owns or operates the network. The infrastructure is collectively maintained by a decentralized public user base. As the network is decentralized, it does not rely on either governmental authorities or financial institutions to create, transmit or determine the value of the currency units. Rather, the value is determined by market factors, supply and demand for the units, the prices being set in transfers by mutual agreement or barter among transacting parties, as well as the number of merchants that may accept the cryptocurrency. Since transfers do not require involvement of intermediaries or third parties, there are currently little to no transaction costs in direct peer-to-peer transactions. Units of cryptocurrency can be converted to fiat currencies, such as the US dollar, at rates determined on various exchanges, such as Cumberland, Coinsquare (in Canada), Coinbase, Bitsquare, Bitstamp, and others. Cryptocurrency prices are quoted on various exchanges and fluctuate with extreme volatility.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif;

Bitcoin is a consensus network that enables a new payment system and a completely new form of digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, we believe bitcoin can be viewed as cash for the Internet. The bitcoin network shares a public ledger called the “blockchain.” This ledger contains every transaction ever processed, allowing a user’s computer to verify the validity of each transaction. The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses, allowing all users to have full control over sending bitcoins currency rewards from their own bitcoin addresses. In addition, anyone can process transactions using the computing power of specialized hardware and earn a reward in bitcoins for this service. This process is often called “mining.”</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">As with many new and emerging technologies, there are potentially significant risks.

Factors such as access to computer processing capacity, interconnectivity, electricity cost, environmental factors (such as cooling capacity) and location play an important role in “mining,” which is the term for using the specialized computers in connection with the blockchain for the creation of new units of cryptocurrency.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b>Mathematically Controlled Supply</b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The method for creating new bitcoins is mathematically controlled in a manner so that the supply of bitcoins grows at a limited rate pursuant to a pre-set schedule. The number of bitcoins awarded for solving a new block is automatically halved every 210,000 blocks. Thus, the current fixed reward for solving a new block is 12.5 bitcoins per block and the reward decreased by half to become 6.25 bitcoins around May 10, 2020, which is the current reward (based on estimates of the rate of block solution calculated by BitcoinClock.com). This deliberately controlled rate of bitcoin creation means that the number of bitcoins in existence will never exceed 21 million and that bitcoins cannot be devalued through excessive production unless the Bitcoin Network’s source code (and the underlying protocol for bitcoin issuance) is altered. The Company monitors the Blockchain network and, as of December 9, 2020, based on the information we collected from our network access, more than 18.45 million bitcoins have been mined.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b>Digital Asset Mining</b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">We intend to power and secure blockchains by verifying blockchain transactions using custom hardware and software.

Blockchains enable the existence of digital assets by allowing participants to confirm transactions without the need for a central certifying authority. When a participant requests a transaction, a peer-to-peer network consisting of computers, known as nodes, validate the transaction and the user’s status using known algorithms. After the transaction is verified, it is combined with other transactions to create a new block of data for the ledger. The new block is added to the existing blockchain in a way that is permanent and unalterable, and the transaction is complete.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Digital assets (also known as cryptocurrency) are a medium of exchange that uses encryption techniques to control the creation of monetary units and to verify the transfer of funds. Many consumers use digital assets because it offers cheaper and faster peer-to-peer payment options without the need to provide personal details. Every single transaction and the ownership of every single digital asset in circulation is recorded in the blockchain. Miners use powerful computers that tally the transactions to run the blockchain. These miners update each time a transaction is made and ensure the authenticity of information. The miners receive a transaction fee for their service in the form of a portion of the new digital “coins” that are issued.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <!-- Field: Page; Sequence: 14; Value: 2 --> <div style="border-bottom: Black 1.5pt solid; margin-bottom: 6pt"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="text-align: center; width: 100%"><!-- Field: Sequence; Type: Arabic; Name: PageNo -->14<!-- Field: /Sequence --></td></tr></table></div> <div style="break-before: page; margin-top: 6pt"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="text-align: center; width: 100%"> </td></tr></table></div> <!-- Field: /Page --> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b><i> </i></b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b><i>Performance Metrics – Hashing</i></b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">We operate mining hardware which performs computational operations in support of the blockchain measured in “hash rate” or “hashes per second.” A “hash” is the computation run by mining hardware in support of the blockchain; therefore, a miner’s “hash rate” refers to the rate at which it is capable of solving such computations. The original equipment used for mining bitcoin utilized the Central Processing Unit (CPU) of a computer to mine various forms of cryptocurrency. Due to performance limitations, CPU mining was rapidly replaced by the Graphics Processing Unit (GPU), which offers significant performance advantages over CPUs. General purpose chipsets like CPUs and GPUs have since been replaced in the mining industry by Application Specific Integrated Circuits (ASIC) chips.

This misuse, or the perception of such misuse (even if untrue), could lead to greater regulatory oversight of bitcoin platforms, and there is the possibility that law enforcement agencies could close bitcoin platforms or other bitcoin-related infrastructure with little or no notice and prevent users from accessing or retrieving bitcoin held via such platforms or infrastructure. For example, in her January 2021 nomination hearing before the Senate Finance Committee, Treasury Secretary Janet Yellen noted that cryptocurrencies have the potential to improve the efficiency of the financial system but that they can be used to finance terrorism, facilitate money laundering, and support malign activities that threaten U.S. national security interests and the integrity of the U.S. and international financial systems. Accordingly, Secretary Yellen expressed her view that federal regulators needed to look closely at how to encourage the use of cryptocurrencies for legitimate activities while curtailing their use for malign and illegal activities. Furthermore, in December 2020, the Financial Crimes Enforcement Network (“FinCEN”), a unit of the Treasury Department focused on money laundering, proposed a new set of rules for cryptocurrency-based exchanges aimed at reducing the use of cryptocurrencies for money laundering. These proposed rules would require filing reports with FinCEN regarding cryptocurrency transactions in excess of $10,000 and also impose record-keeping requirements for cryptocurrency transactions in excess of $3,000 involving users who manage their own private keys. In January 2021, the Biden Administration issued a memorandum freezing federal rulemaking, including these proposed FinCEN rules, to provide additional time for the Biden Administration to review the rulemaking that had been proposed by the Trump Administration. As a result, it remains unclear whether these proposed rules will take effect.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b><span style="text-decoration: underline">Intellectual Property</span></b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">We actively use specific hardware and software for our cryptocurrency mining operation.

An intangible asset with an indefinite useful life is not amortized, but rather is assessed for impairment annually, or more frequently, when events or changes in circumstances occur which indicate that it is more likely than not that the indefinite-lived asset is impaired. Impairment exists when the carrying amount exceeds its fair value. In testing for impairment, the Company will have the option to first perform a qualitative assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more likely than not that an impairment exists, a quantitative impairment test is not necessary. If the Company concludes otherwise, it is required to perform a quantitative impairment test. To the extent an impairment loss is recognized, the loss establishes the new cost basis of the asset. Subsequent reversal of impairment losses is not permitted. Realized gain or loss on the sale of digital currencies is included in other income or expenses in the Company’s statements of operations.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><span class="alphaminr_link" id="alphaminr_3" style="display:inline-block"/><b><span id="a_003"/>ITEM 1A.

In the event that the digital assets other than bitcoin held by us exceed 40% of our total assets, exclusive of cash, we inadvertently become an investment company. An inadvertent investment company can avoid being classified as an investment company if it can rely on one of the exclusions under the 1940 Act. One such exclusion, Rule 3a-2 under the 1940 Act, allows an inadvertent investment company a grace period of one year from the earlier of (a) the date on which an issuer owns securities and/or cash having a value exceeding 50% of the issuer’s total assets on either a consolidated or unconsolidated basis and (b) the date on which an issuer owns or proposes to acquire investment securities having a value exceeding 40% of the value of such issuer’s total assets (exclusive of government securities and cash items) on an unconsolidated basis. We are putting in place policies that we expect will work to keep the investment securities held by us at less than 40% of our total assets, which may include acquiring assets with our cash, liquidating our investment securities or seeking a no-action letter from the SEC if we are unable to acquire sufficient assets or liquidate sufficient investment securities in a timely manner.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">As Rule 3a-2 is available to a company no more than once every three years, and assuming no other exclusion were available to us, we would have to keep within the 40% limit for at least three years after we cease being an inadvertent investment company.

If an investment company fails to register, it would have to stop doing almost all business, and its contracts would become voidable. Registration is time consuming and restrictive and would require a restructuring of our operations, and we would be very constrained in the kind of business we could do as a registered investment company. Further, we would become subject to substantial regulation concerning management, operations, transactions with affiliated persons and portfolio composition, and would need to file reports under the 1940 Act regime. The cost of such compliance would result in the Company incurring substantial additional expenses, and the failure to register if required would have a materially adverse impact to conduct our operations. If we determine to mine cryptocurrencies, other than bitcoin in the future, we will establish and disclose the process and framework we use to determine if such digital assets are securities under Section 2(a)(1) of the Securities Act and will address any specific risks in our policy and framework in making such a determination.

These individuals can propose refinements or improvements to the bitcoin network’s source code through one or more software upgrades that alter the protocols and software that govern the bitcoin network and the properties of bitcoin, including the irreversibility of transactions and limitations on the mining of new bitcoin. Proposals for upgrades and discussions relating thereto take place on online forums. For example, there is an ongoing debate regarding altering the blockchain by increasing the size of blocks to accommodate a larger volume of transactions. Although some proponents support an increase, other market participants oppose an increase to the block size as it may deter miners from confirming transactions and concentrate power into a smaller group of miners. To the extent that a significant majority of the users and miners on the bitcoin network install such software upgrade(s), the bitcoin network would be subject to new protocols and software that may adversely affect an investment in the Shares. In the event a developer or group of developers proposes a modification to the bitcoin network that is not accepted by a majority of miners and users, but that is nonetheless accepted by a substantial plurality of miners and users, two or more competing and incompatible blockchain implementations could result. This is known as a “hard fork.” In such a case, the “hard fork” in the blockchain could materially and adversely affect the perceived value of digital assets as reflected on one or both incompatible blockchains, which may adversely affect an investment in us.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b><i>The open-source structure of the bitcoin network protocol means that the contributors to the protocol are generally not directly compensated for their contributions in maintaining and developing the protocol.

Although the MIT Media Lab’s Digital Currency Initiative funds the current maintainer Wladimir J. van der Laan, among others, this type of financial incentive is not typical. The lack of guaranteed financial incentive for contributors to maintain or develop the bitcoin network and the lack of guaranteed resources to adequately address emerging issues with the bitcoin network may reduce incentives to address the issues adequately or in a timely manner.

The miner becomes aware of outstanding, unrecorded transactions through the data packet transmission and propagation discussed above. Typically, bitcoin transactions will be recorded in the next chronological block if the spending party has an internet connection and at least one minute has passed between the transaction’s data packet transmission and the solution of the next block.

It is estimated that it will halve again in about four (4) years. This reduction may result in a reduction in the aggregate hashrate of the bitcoin network as the incentive for miners will decrease. Moreover, miners ceasing operations would reduce the aggregate hashrate on the bitcoin network, which would adversely affect the confirmation process for transactions (i.e., temporarily decreasing the speed at which blocks are added to the blockchain until the next scheduled adjustment in difficulty for block solutions) and make the bitcoin network more vulnerable to a malicious actor obtaining control in excess of fifty percent (50%) of the aggregate hashrate on the bitcoin network.

Currently, new processing power brought onto the digital asset networks is predominantly added by incorporated and unincorporated “professionalized” mining operations. Professionalized mining operations may use proprietary hardware or sophisticated machines. They require the investment of significant capital for the acquisition of this hardware, the leasing of operating space (often in data centers or warehousing facilities), incurring of electricity costs and the employment of technicians to operate the mining farms. As a result, professionalized mining operations are of a greater scale than prior miners and have more defined, regular expenses and liabilities. These regular expenses and liabilities require professionalized mining operations to more immediately sell digital assets earned from mining operations on the digital asset exchange market, whereas it is believed that individual miners in past years were more likely to hold newly mined digital assets for more extended periods. The immediate selling of newly mined digital assets greatly increases the supply of digital assets on the digital asset exchange market, creating downward pressure on the price of each digital asset.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The extent to which the value of digital assets mined by a professionalized mining operation exceeds the allocable capital and operating costs determines the profit margin of such operation. A professionalized mining operation may be more likely to sell a higher percentage of its newly mined digital assets rapidly if it is operating at a low profit margin—and it may partially or completely cease operations if its profit margin is negative. In a low profit margin environment, a higher percentage could be sold into the digital asset exchange market more rapidly, thereby potentially reducing digital asset prices. Lower digital asset prices could result in further tightening of profit margins, particularly for professionalized mining operations with higher costs and more limited capital reserves, creating a network effect that may further reduce the price of digital assets until mining operations with higher operating costs become unprofitable and remove mining power from the respective digital asset network. The network effect of reduced profit margins resulting in greater sales of newly mined digital assets could result in a reduction in the price of digital assets that could adversely impact an investment in us.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b><i>To the extent that any miners cease to record transactions in solved blocks, transactions that do not include the payment of a transaction fee will not be recorded on the blockchain until a block is solved by a miner who does not require the payment of transaction fees.

This kind of split in the bitcoin network could materially and adversely impact an investment in us and, in the worst-case scenario, harm the sustainability of the bitcoin network’s economy.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b><i>Intellectual property rights claims may adversely affect the operation of some or all digital asset networks.</i></b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; text-indent: 0.5in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Third parties may assert intellectual property claims relating to the holding and transfer of digital assets and their source code.

In July 2016, North Carolina updated the law to define “virtual currency” and the activities that trigger licensure in a business-friendly approach that encourages companies to use virtual currency and blockchain technology. Specifically, the North Carolina law does not require miners or software providers to obtain a license for multi-signature software, smart contract platforms, smart property, colored coins and non-hosted, non-custodial wallets. Starting January 1, 2016, New Hampshire requires anyone who exchanges a digital currency for another currency must become a licensed and bonded money transmitter.

For example, the application of securities laws and other regulations to such assets is unclear in certain respects, and it is possible that regulators in the United States or foreign countries may create new regulations or interpret laws in a manner that adversely affects the price of bitcoin. The growth of the digital assets industry in general, and the use and acceptance of bitcoin in particular, may also impact the price of bitcoin and is subject to a high degree of uncertainty. The pace of worldwide growth in the adoption and use of bitcoin may depend, for instance, on public familiarity with digital assets, ease of buying and accessing bitcoin, institutional demand for bitcoin as an investment asset, consumer demand for bitcoin as a means of payment, and the availability and popularity of alternatives to bitcoin. Even if growth in bitcoin adoption occurs in the near or medium-term, there is no assurance that bitcoin usage will continue to grow over the long-term. Because bitcoin has no physical existence beyond the record of transactions on the Bitcoin blockchain, a variety of technical factors related to the Bitcoin blockchain could also impact the price of bitcoin. For example, malicious attacks by “miners” who validate bitcoin transactions, inadequate mining fees to incentivize validating of bitcoin transactions, hard “forks” of the Bitcoin blockchain into multiple blockchains, and advances in quantum computing could undercut the integrity of the Bitcoin blockchain and negatively affect the price of bitcoin. The liquidity of bitcoin may also be reduced and damage to the public perception of bitcoin may occur, if financial institutions were to deny banking services to businesses that hold bitcoin, provide bitcoin-related services or accept bitcoin as payment, which could also decrease the price of bitcoin.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b><i>If we or our third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to our bitcoin, we may lose some or all of our bitcoin and our financial condition and results of operations could be materially adversely affected</i></b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Security breaches and cyberattacks are of particular concern with respect to our bitcoin.

In addition, since publication of discoveries in scientific or patent literature often lags behind actual discoveries, we cannot be certain that we will be the first to make our additional new inventions or to file patent applications covering those inventions. It is also possible that others may have or may obtain issued patents that could prevent us from commercializing our products or require us to obtain licenses requiring the payment of significant fees or royalties in order to enable us to conduct our business.

(the “Company”) in the Superior Court of the State of California for the County of Riverside. The Complaint alleges six causes of action against the Company, (1) Breach of Written Contract; (2) Breach of Implied Contract; (3) Quasi-Contract; (4) Services Rendered; (5) Intentional Interference with Prospective Economic Relations; and (6) Negligent Interference with Prospective Economic Relations.  The Complaint seeks damages, restitution, punitive damages, and costs of suit. The claims arise from the same set of facts. Ho alleges that the Company profited from commercially-sensitive information he shared with the Company, purportedly under a mutual non-disclosure agreement, and that the Company failed to compensate him for his role in securing the acquisition of a supplier of energy for the Company. On February 22, 2021, the Company responded to Mr. Ho’s Complaint with a general denial and the assertion of applicable affirmative defenses. Then, on February 25, 2021, the Company removed the action to the United States District Court in the Central District of California, where the action remains pending. Marathon filed a motion for summary judgment/adjudication of all causes of action.  On February 11, 2022, the Court granted the motion and dismissed Ho’s 2<sup>nd</sup>, 5<sup>th</sup> and 6<sup>th</sup> causes of action.  Discovery is closed.  The Court held a pre-trial conference on February 24, 2022, where it vacated the March 3, 2022 trial date and ordered the parties to meet and confer on a new trial date, which will likely be after June 2022, given the Court’s current backlog as a result of Covid.  The Court discussed the various theories of damages maintained by the parties.  In its ruling on the summary judgment motion and at the pre-trial conference on February 24, 2022, the Court noted that a jury is more likely to accept $150,000 as an appropriate damages amount if liability is found, as opposed to the various theories espoused by Ho that result in multi-million dollar recoveries.  Due to outstanding issues of fact and law, it is impossible to predict the outcome at this time; however, after consulting legal counsel, the Company is confident that it will prevail in this litigation, since it did not have a contract with Mr. Ho and he did not disclose any commercially-sensitive information under any mutual nondisclosure agreement that was used to structure any joint venture with energy providers. Trial is set to begin on May 26, 2022.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">During the quarter ended September 30, 2021, the Company and certain of its executives received a subpoena to produce documents and communications concerning the Hardin, Montana data center facility described in our Form 8-K dated October 13, 2020.

As of the date of this filing, our name has been changed to Marathon Digital Holdings, Inc. On December 7, 2011, we changed our name to American Strategic Minerals Corporation and were engaged in exploration and potential development of uranium and vanadium minerals business. In June 2012, we discontinued our minerals business and began to invest in real estate properties in Southern California. In October 2012, we discontinued our real estate business and we commenced our IP licensing operations, at which time the Company’s name was changed to Marathon Patent Group, Inc. On November 1, 2017, we entered into a merger agreement with Global Bit Ventures, Inc. (“GBV”), which is focused on mining digital assets. We have since purchased our cryptocurrency mining machines and established a data center in Canada to mine digital assets. Following the merger, we intended to add GBV’s existing technical capabilities and digital asset miners and expand our activities in the mining of new digital assets, while at the same time harvesting the value of our remaining IP assets. On June 28, 2018, the board has determined that it is in the best interests of the Company and its shareholders to allow the Amended Merger Agreement to expire on its current termination date of June 28, 2018 without further negotiation or extension. The Board approved to issue 750,000 shares of our common stock to GBV as a termination fee for cancelling the proposed merger between the two companies. The fair value of the common stocks was $2,850,000.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <!-- Field: Page; Sequence: 41; Value: 2 --> <div style="border-bottom: Black 1.5pt solid; margin-bottom: 6pt"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="text-align: center; width: 100%"><!-- Field: Sequence; Type: Arabic; Name: PageNo -->41<!-- Field: /Sequence --></td></tr></table></div> <div style="break-before: page; margin-top: 6pt"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="text-align: center; width: 100%"> </td></tr></table></div> <!-- Field: /Page --> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b><span style="text-decoration: underline">Recent Developments</span></b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b>See “Business – Recent Developments”</b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><span style="text-decoration: underline">Critical Accounting Policies and Estimates</span></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify; background-color: white"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">We believe that the following accounting policies are the most critical to aid you in fully understanding and evaluating this management discussion and analysis:</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><span style="text-decoration: underline">Digital Currencies</span></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">Digital currencies are included in current assets in the consolidated balance sheets as intangible assets with indefinite useful lives.

Impairment exists when the carrying amount exceeds its fair value, which is measured using the quoted price of the digital currency at the time its fair value is being measured. In testing for impairment, the Company has the option to first perform a qualitative assessment to determine whether it is more likely than not that an impairment exists. If it is determined that it is not more likely than not that an impairment exists, a quantitative impairment test is not necessary. If the Company concludes otherwise, it is required to perform a quantitative impairment test. To the extent an impairment loss is recognized, the loss establishes the new cost basis of the asset. Subsequent reversal of impairment losses is not permitted.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">At December 31, 2021, we carried $123.2 million of digital assets on our balance sheet, consisting of the approximately 3,321 bitcoins, and held $268.5 million in cash and cash equivalents, compared to $2.3 million of digital assets and $141.3 million in cash and cash equivalents at December 31, 2020, reflecting the shift in our liquid assets.

Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. On January 14, 2021, the Company sold its inventory of approximately 5,900 S9, 13.5 TH/s miners. As such, management determined that those crypto-currency machines were impaired by a total of $871,302 based upon an assessment as of December 31, 2020. During the year ended December 31, 2019 we moved certain of our bitcoin miners to a new location in the United States and recorded an impairment of $447,776 in our leasehold improvements in Canada. <b/></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b> </b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><span style="text-decoration: underline">Non-GAAP Financial Measures</span></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">We are providing supplemental financial measures for (i) non-GAAP income from operations that excludes the impact of depreciation and amortization of fixed assets, impairment losses on mined cryptocurrency, server maintenance contract amortization and stock compensation expense and (ii) non-GAAP net income and non-GAAP diluted earnings per share that exclude the impact of depreciation and amortization of fixed assets, impairment losses on mined cryptocurrency, change in fair value of warrant liability, server maintenance contract amortization and stock compensation expense, net of withholding taxes.

Similarly, we expect that depreciation and amortization of fixed assets will continue to be a recurring expense over the term of the useful life of the assets. We have also excluded impairment losses on mined cryptocurrency from the first two non-GAAP financial measures, which may occur in future periods as a result of our continued holdings of significant amounts of bitcoin.

During times of instability in the Bitcoin market, we may not be able to sell our bitcoins at reasonable prices or at all. As a result, our bitcoins are less liquid than our existing cash and cash equivalents and may not be able to serve as a source of liquidity for us to the same extent as cash and cash equivalents.

The carrying value of our bitcoins as of December 31, 2021 was $42,667, which reflects cumulative impairments of $29.6 million, on our Consolidated Balance Sheet. As discussed in Note 2, Summary of Significant Accounting Policies, to the Consolidated Financial Statements, we account for our bitcoin as indefinite-lived intangible assets, which are subject to impairment losses if the fair value of our bitcoin decreases below their carrying value at any time since their acquisition. Impairment losses cannot be recovered for any subsequent increase in fair value. For example, the market price of one bitcoin in our principal market ranged from $46,178 - $67,634 during the three months ended December 31, 2021, but the carrying value of each bitcoin we held at the end of the reporting period reflects the lowest price of one bitcoin quoted on the active exchange at any time since its acquisition. Therefore, negative swings in the market price of bitcoin could have a material impact on our earnings and on the carrying value of our digital assets. Positive swings in the market price of bitcoin are not reflected in the carrying value of our digital assets and impact earnings only when the bitcoin is sold at a gain. For the year ended December 31, 2021, we incurred impairment losses of $29.6 million on our bitcoin. As of March 9, 2022, at 4:00 p.m. EST, the market price of one bitcoin in our principal market was $38,900.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <!-- Field: Page; Sequence: 49; Value: 2 --> <div style="border-bottom: Black 1.5pt solid; margin-bottom: 6pt"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="text-align: center; width: 100%"><!-- Field: Sequence; Type: Arabic; Name: PageNo -->49<!-- Field: /Sequence --></td></tr></table></div> <div style="break-before: page; margin-top: 6pt"><table cellpadding="0" cellspacing="0" style="border-collapse: collapse; width: 100%; font-size: 10pt"><tr style="vertical-align: top; text-align: left"><td style="text-align: center; width: 100%"> </td></tr></table></div> <!-- Field: /Page --> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><span class="alphaminr_link" id="alphaminr_13" style="display:inline-block"/><b><span id="a_013"/>ITEM 8.

On December 7, 2011, the Company changed its name to American Strategic Minerals Corporation and were engaged in exploration and potential development of uranium and vanadium minerals business. In June 2012, the Company discontinued the minerals business and began to invest in real estate properties in Southern California. In October 2012, the Company discontinued its real estate business and the Company commenced IP licensing operations, at which time the Company’s name was changed to Marathon Patent Group, Inc. On November 1, 2017, the Company entered into a merger agreement with Global Bit Ventures, Inc. (“GBV”), which is focused on mining digital assets. The Company purchased cryptocurrency mining machines and established a data center in Canada to mine digital assets. The Company expanded its activities in the mining of new digital assets, while at the same time harvesting the value of its remaining IP assets. As of October 2020, the financial operations were brought in house and are completed by the Company’s accounting team that consists of a Chief Financial Officer, Chief Operating Officer and bookkeeper. Subsequent to December 31, 2020, the Company hired a full-time Controller.

Lease liabilities are increased by interest and reduced by payments each period, and the right of use asset is amortized over the lease term.

Amongst other provisions, the amendments in this ASU significantly change the guidance on the issuer’s accounting for convertible instruments and the guidance on the derivative scope exception for contracts in an entity’s own equity such that fewer conversion features will require separate recognition, and fewer freestanding instruments, like warrants, will require liability treatment.

Feinberg Personal Trust and the Jeffrey L. Feinberg Family Trust, filed a complaint against the Company and certain of its former officers and directors. The complaint was filed in the Supreme Court of the State of New York, County of New York. The plaintiffs purported to state claims under Sections 11, 12(a)(2) and 15 of the federal Securities Act of 1933 and common law claims for “actual fraud and fraudulent concealment,” constructive fraud, and negligent misrepresentation, seeking unspecified money damages (including punitive damages), as well as costs and attorneys’ fees, and equitable or injunctive relief. On June 15, 2018, the defendants filed a motion to dismiss all claims asserted in the complaint and, on July 27, 2018, the plaintiffs filed an opposition to that motion. The court heard argument on the motion and, on January 15, 2019, the court granted the motion to dismiss, allowing 30 days for the filing of an amended complaint. On February 15, 2019, Jeffrey Feinberg, individually and as trustee of the Jeffrey L. Feinberg Personal Trust, and Terrence K. Ankner, as trustee of the Jeffrey L. Feinberg Family Trust, filed an amended complaint that purports to state the same claims and seeks the same relief sought in the original complaint. On March 7 and 22, 2019, defendants filed motions to dismiss the amended complaint and on April 5, 2019, plaintiffs filed an opposition to those motions. The court heard oral argument on the motions to dismiss on July 9, 2019, and at the conclusion of the argument the court took the motions under submission. On March 13, 2020, the court issued its Decision in which it granted the motions to dismiss in full and ordered that the case be dismissed with prejudice. On or about May 4, 2020, the plaintiffs filed a notice of appeal. Plaintiffs filed their opening appellate brief on January 4, 2021, and defendants filed their responsive appellate briefs on February 3, 2021. Oral argument on the appeal was conducted on April 1, 2021. On April 22, 2021, the court’s Appellate Division issued its Decision and Order affirming the dismissal of the case.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><i>Ho Matter</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><i> </i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">On January 14, 2021, Plaintiff Michael Ho (“Plaintiff” or “Ho”) filed a Civil Complaint for Damages and Restitution (“Complaint”) against Marathon Patent Group, Inc., now known as Marathon Digital Holdings, Inc. (the “Company”) in the Superior Court of the State of California for the County of Riverside. The Complaint alleges six causes of action against the Company, (1) Breach of Written Contract; (2) Breach of Implied Contract; (3) Quasi-Contract; (4) Services Rendered; (5) Intentional Interference with Prospective Economic Relations; and (6) Negligent Interference with Prospective Economic Relations.  The Complaint seeks damages, restitution, punitive damages, and costs of suit. The claims arise from the same set of facts. Ho alleges that the Company profited from commercially-sensitive information he shared with the Company, purportedly under a mutual non-disclosure agreement, and that the Company failed to compensate him for his role in securing the acquisition of a supplier of energy for the Company. On February 22, 2021, the Company responded to Mr. Ho’s Complaint with a general denial and the assertion of applicable affirmative defenses. Then, on February 25, 2021, the Company removed the action to the United States District Court in the Central District of California, where the action remains pending. Marathon filed a motion for summary judgment/adjudication of all causes of action.  On February 11, 2022, the Court granted the motion and dismissed Ho’s 2<sup>nd</sup>, 5<sup>th</sup> and 6<sup>th</sup> causes of action.  Discovery is closed.  The Court held a pre-trial conference on February 24, 2022, where it vacated the March 3, 2022 trial date and ordered the parties to meet and confer on a new trial date, which will likely be after June 2022, given the Court’s current backlog as a result of Covid.  The Court discussed the various theories of damages maintained by the parties.  In its ruling on the summary judgment motion and at the pre-trial conference on February 24, 2022, the Court noted that a jury is more likely to accept $<span id="xdx_90A_eus-gaap--LossContingencyDamagesAwardedValue_c20210111__20210114__us-gaap--LossContingenciesByNatureOfContingencyAxis__custom--PlaintiffMichaelHoMember_zlwOwIAymCmg" title="Damages amount"><ix:nonFraction contextRef="From2021-01-112021-01-14_custom_PlaintiffMichaelHoMember" decimals="0" format="ixt:numdotdecimal" name="us-gaap:LossContingencyDamagesAwardedValue" unitRef="USD">150,000</ix:nonFraction></span> as an appropriate damages amount if liability is found, as opposed to the various theories espoused by Ho that result in multi-million dollar recoveries.  Due to outstanding issues of fact and law, it is impossible to predict the outcome at this time; however, after consulting legal counsel, the Company is confident that it will prevail in this litigation, since it did not have a contract with Mr. Ho and he did not disclose any commercially-sensitive information under any mutual nondisclosure agreement that was used to structure any joint venture with energy providers. Trial is set to begin on May 26, 2022. </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><i> </i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><i>Information Subpoena</i></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">On October 6, 2020, the Company entered into a series of agreements with multiple parties to design and build a data center for up to 100-megawatts in Hardin, MT.

The Disclosure Controls evaluation was done under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, with the goal being that the information required to be disclosed by us in reports filed under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding disclosure.

In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control - Integrated Framework in the 2013 COSO framework. Based on this evaluation, management identified a weakness in internal control over financial reporting related to Information Technology General Controls (ITGC). Specifically, the Company did not design and/or implement user access controls to ensure appropriate segregation of duties or program change management controls for certain financially relevant systems impacting the Company’s processes around revenue recognition and digital assets to ensure that IT program and data changes affecting the Company’s (i) financial IT applications, (ii) digital currency mining equipment, and (iii) underlying accounting records, are identified, tested, authorized and implemented appropriately to validate that data produced by its relevant IT system(s) were complete and accurate. Automated process-level controls and manual controls that are dependent upon the information derived from such financially relevant systems were also determined to be ineffective as a result of such deficiency. In addition, the Company has not effectively designed a manual key control to detect material misstatements in revenue.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="letter-spacing: -0.05pt"/></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; letter-spacing: -0.25pt; text-indent: 0in"><span style="letter-spacing: 0pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; letter-spacing: -0.25pt; text-indent: 0in"><span style="letter-spacing: 0pt">The material weakness described above did not result in a material misstatement to the Company’s previously issued consolidated financial statements, nor</span> in the consolidated financial statements included in this Annual Report on Form 10-K.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; letter-spacing: -0.25pt; text-indent: 0in"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The effectiveness of our internal control over financial reporting as of December 31, 2021, has been audited by our independent registered public accounting firm, Marcum, LLP, as stated in their report on management’s internal control over financial reporting, which is also included in Item 8, “Financial Statements and Supplementary Data,” of this 2021 Form 10-K.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; background-color: white"><b> </b></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; background-color: white"><b>Remediation</b></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white">As noted above, during the initial audit over the internal controls over financial <span style="letter-spacing: -0.05pt">reporting (“ICFR”) a material weakness was identified related to certain ITGCs over user access, segregation of duties and change management controls.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"><span style="letter-spacing: -0.05pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"><span style="letter-spacing: -0.05pt">As management is responsible for maintaining effective internal control over financial reporting, and for its assessment of</span> <span style="letter-spacing: -0.1pt">the effectiveness of internal control over financial reporting, we understand the importance of developing a resolution plan aligned with management and overseen by the Audit Committee of our Board of Directors.
