CORPORATE OVERVIEW
Marathon is a digital asset technology company that is principally engaged in producing or “mining” digital assets with a focus on the Bitcoin ecosystem. Our strategic initiatives primarily focus on mining and holding bitcoin as a long-term investment. Bitcoin is seeing increasing adoption, and, due to its limited supply, we believe it offers opportunity for appreciation in value and long-term growth prospects for our business.
In addition to mining and holding bitcoin, from time to time we have explored, and we may in the future explore, opportunities to become more involved in businesses that expand or supplement those directly related to the self-mining of bitcoin as favorable market conditions and opportunities arise. For example, we have considered or engaged in owning and operating bitcoin mining facilities or data centers, selling proprietary software or technology to third parties operating in the Bitcoin ecosystem, offering advisory and consulting services to support bitcoin mining ventures in domestic and international jurisdictions, and generating electricity from renewable energy resources or methane gas capture to power bitcoin mining projects. The Company is committed to carbon neutrality and growing operations through predominately renewable energy sources. Our business is also active in Bitcoin-related projects related to the technological development of immersion, hardware, firmware, mining pools and side chains that use the blockchain cryptography.
As used throughout this Annual Report, the term “Bitcoin” with a capital “B” is used to denote the Bitcoin protocol which implements a highly available, public, permanent, and decentralized ledger. The term “bitcoin” with a lower case “b” is used to denote the token, bitcoin.
BITCOIN BLOCKCHAIN
Bitcoin and Bitcoin Mining
Bitcoin is a decentralized digital asset that operates on a peer-to-peer network, allowing users to send and receive payments without the need for banks and other intermediaries. Bitcoin is not linked to any fiat currency or country’s monetary policy, therefore serves as a store of value outside of government control. This is possible by using blockchain technology, which is a distributed ledger that records and verifies all transactions on the network.
The Bitcoin blockchain is a public, transparent, and unalterable record of all transactions that have ever occurred on the peer-to-peer network. When a user sends a transaction on the Bitcoin network, it is broadcast to the network and added to a pool of unconfirmed transactions known as the “mempool.” Mining rigs then compete in a sort of lottery to “solve a block,” which confirms a transaction and adds it to the blockchain, and the mining rig receives a reward in the form of newly minted bitcoin. Each confirmed transaction is cryptographically signed and permanently recorded in the blockchain as a new block, and cannot be altered or deleted.
The block chain is maintained by a robust and public open-source architecture consisting of a network of computers, known as nodes, that work together to verify and validate new transactions. Because the blockchain is decentralized and transparent, all users can verify the legitimacy of a transaction without having to rely on a third party. This eliminates the need for intermediaries, which can be slow and expensive, and makes the network resistant to censorship and fraud.
Bitcoin mining plays a key role in the maintenance and growth of the Bitcoin network by providing the computational power needed to verify transactions and add new blocks to the blockchain. As consumers increasingly become interested in mining bitcoin, the network becomes more secure and efficient.
As of December 31, 2023, we operated approximately 210,000 mining rigs globally, with an installed and energized hash rate of approximately 25.2 and 24.7 exahashes per second, respectively. During the year ended December 31, 2023, we mined 12,852 bitcoin, an increase of 8,708 bitcoin, or 210.1%, over the prior year. We remain focused on maximizing our chances of successfully solving blocks on the Bitcoin blockchain by growing our hash rate, or the amount of computational power we devote to supporting the bitcoin blockchain, to enhance our ability to successfully solving blocks. Generally, the greater the share a single mining rig can capture of the blockchain’s total network hash rate, or the aggregate hash rate deployed to solving a block on the Bitcoin blockchain, the greater the rig’s chances of solving a block and therefore earning the reward. Currently, the reward for each solved block is equal to 6.25 bitcoin plus transaction fees and, as of December 31, 2023, the price of a bitcoin was $42,288. As additional mining operators enter the market in response to increased demand for bitcoin, the blockchain’s network hash rate grows. As we expect this trend to continue, we will need to continue to grow our hash rate to compete in our dynamic and highly competitive industry.

Bitcoin “Halving” Events
Bitcoin halving is a phenomenon that has historically occurred approximately every four years on the Bitcoin network. Halving is a key part of the Bitcoin protocol and serves to control the overall supply and reduce the risk of inflation in digital assets using a Proof-of-Work consensus algorithm. At a predetermined block, the mining reward is cut in half, hence the term “halving.” For example, the reward for adding a single block to the blockchain was initially set at 50 bitcoin currency rewards. The Bitcoin blockchain has undergone halving three times since its inception as follows: (1) on November 28, 2012 at block height 210,000; (2) on July 9, 2016 at block height 420,000; and (3) on May 11, 2020 at block height 630,000, when the reward was reduced to its current level of 6.25 bitcoin per block. The next halving for the Bitcoin blockchain is anticipated to occur around April 2024 at block height 840,000. This process will recur until the total amount of bitcoin currency rewards issued reaches 21.0 million, and the theoretical supply of new bitcoin is exhausted, which is expected to occur around 2140. Many factors influence the price of Bitcoin, and potential increase or decrease in prices in advance of or following the future halving is unknown.
Factors Affecting Profitability
Market Price of Bitcoin
Our business is heavily dependent on the price of bitcoin. The prices of digital assets, including bitcoin, have historically experienced substantial volatility, and digital asset prices have in the past and may in the future be driven by speculation and incomplete information, subject to rapidly changing investor sentiment, and influenced by factors such as technology, macroeconomic conditions, regulatory void or changes, fraudulent actors, manipulation, and media reporting. Further, the value of bitcoin and other digital assets may be significantly impacted by factors beyond our control, including consumer trust in the market acceptance of bitcoin as a means of exchange by consumers and producers.
Halving
The halving is an important part of the Bitcoin ecosystem, and it is closely watched by miners, investors, and other participants in the digital asset market. Each halving event has historically been associated with significant price movements in the value of bitcoin.
Network Hash Rate and Difficulty
Generally, a bitcoin mining rig’s chance of solving a block on the Bitcoin blockchain and earning a bitcoin reward is a function of the mining rig’s hash rate, relative to the global network hash rate (i.e., the aggregate amount of computing power devoted to supporting the Bitcoin blockchain at a given time). As demand for bitcoin increases, the global network hash rate rapidly increases, and as more adoption of bitcoin occurs, we expect the demand for new bitcoin will likewise increase as more mining companies are drawn into the industry by this increase in demand. Further, as more and increasingly powerful mining rigs are deployed, the network difficulty for Bitcoin increases. Network difficulty is a measure of how difficult it is to solve a block on the Bitcoin blockchain, which is adjusted every 2,016 blocks, or approximately every two weeks, so that the average time between each block is approximately ten minutes. A high difficulty means that it will take more computing power to solve a block and earn a new bitcoin reward, which, in turn, makes the Bitcoin network more secure by limiting the possibility of one miner or mining pool gaining control of the network. Therefore, as new and existing miners deploy additional hash rate, the global network hash rate will continue to increase, meaning a miner’s share of the global network hash rate (and therefore its chance of earning bitcoin rewards) will decline if it fails to deploy additional hash rate at pace with the industry.
STRATEGIC FOCUS
Our focus in 2023 was on growth execution and transition into a more mature organization with diversified portfolio of bitcoin mining technologies and assets. This focus consisted of both the expansion of operations of our core bitcoin mining business (operating mining rigs at third-party owned and operated data centers), acquiring and operating bitcoin mining sites to host our own bitcoin mining rigs, and operating MaraPool, our proprietary bitcoin mining pool which orchestrates the operation of our fleet of mining rigs. Key activities and milestones throughout 2023 included the following:
• In December 2023, we entered into a definitive agreement to acquire two currently operational bitcoin mining sites, totaling 390 megawatts of capacity, in Granbury, Texas and Kearney, Nebraska, to reduce the cost per coin of our current operations at these sites and further transition from the asset-light organization to one that manages a diversified and resilient portfolio of bitcoin mining operations. The transaction closed on January 12, 2024;

• We deployed capital to secure the most efficient Application Specific Integrated Circuit mining rigs (“ASICs”) through contracts that included price protection clauses which benefited the Company as ASICs prices declined throughout the second and third quarters of 2023;
• We continued operations at a wind-powered site in McCamey, Texas and other smaller sites, which have increased our use of renewable sources of energy;
• We secured additional hosting services to further our planned expansion of operations, entering into third-party hosting relationships with Applied Digital Corporation (“APLD”) to host S19XP mining rigs at sites in Texas and North Dakota; and
• We increased our hash rate from 7.0 and 7.0 installed and energized exahashes per second, respectively, as of December 31, 2022 to 25.2 and 24.7 installed and energized exahashes per second, respectively, as of December 31, 2023.
The year ended December 31, 2023 was a year of adaptation, as we overcame several operational and financial headwinds that occurred during 2022, including:
• Our primary mining facility in Hardin, Montana went offline after being damaged by a storm in mid-2022;
• Delays in the energization of the McCamey, Texas site during the second and third quarters of 2022;
• Compute North, our largest hosting partner, entered bankruptcy proceedings in September 2022;
• A significant decline in the price of bitcoin, which resulted in impairments of our bitcoin holdings throughout 2022 and an impairment charge related to the value of our mining rigs and certain contracts during the fourth quarter of 2022; and
• Challenging financial markets and macroeconomic conditions throughout 2022.
Our primary focus in 2024 is to keep our current fleet of over 210,000 bitcoin mining rigs energized and running optimally while increasing our total operational hash rate. Our operational hash rate was 7.0 exahashes per second as of December 31, 2022 and was more than 24.7 exahashes per second as of December 31, 2023. We anticipate further growth of our operational hash rate in 2024 as we bring newly acquired bitcoin miners into operation. We expect to increase our operational hash rate to approximately 35 to 37 exahashes per second in 2024. By December 31, 2025, we plan to reach 50 exahashes per second in operational hash rate. To support this growth, we have placed orders with multiple manufacturers for approximately 22 exahashes per second and hold the option to purchase an additional 23 exahashes per second. Additionally, we expect to expand our data center capacity through a portfolio approach with a healthy mix of asset-light, asset-heavy, and joint venture partnerships.
Historically, we have grown quickly to become one of the world’s largest publicly traded bitcoin mining companies. We achieved this milestone through an asset-light strategy, which involved deploying our bitcoin miners at third-party hosted sites. This approach saved us significant amounts of capital that would have otherwise been invested in data center infrastructure and allowed us to allocate more capital into revenue-generating assets, including bitcoin miners. During the year ended December 31, 2023 we shifted our strategy from an asset-light business model to a diversified and resilient portfolio approach directly supporting our bitcoin mining operations. This approach involves managing a strategic mix of third-party hosted sites and self-owned and operated sites, which we believe will help the business weather market downturns by optimizing its cost structure. In January 2024, we acquired two data centers totaling 390 megawatts. Following this acquisition, our operations are moving towards being more evenly split between third-party hosted and self-owned and operated sites.
In 2023, we launched a joint venture in Abu Dhabi, United Arab Emirates, which operates two sites with a total capacity of 250 megawatts, of which we own 20%. These sites operate in one of the world’s most challenging environments, with summertime temperatures of approximately 115 degrees Fahrenheit and 98% humidity. We believe our state-of-the-art immersion technology deployed at these sites has resulted in the bitcoin mining rigs operating with minimal human intervention and need for repairs. In addition, in November 2023 we launched a joint venture project in Paraguay to support 20 megawatts and expect operations to commence at the site during the quarter ending June 30, 2024. We intend to continue our international expansion efforts into 2024.
To support this shift in strategy and to capitalize on opportunities for international expansion and industry consolidation, we strengthened our liquidity position – a priority that we intend to continue focusing on in 2024. Our combined cash and cash equivalents and bitcoin reserve totaled nearly $1.0 billion as of December 31, 2023. Refer to the “Liquidity and Capital Resources” section, for further information.

COMPETITION
In digital asset mining, companies and individuals use computing power to solve cryptographic algorithms to record and publish transactions to blockchain ledgers or provide transaction verification services to the Bitcoin network in exchange for digital asset rewards. The current reward for verifying a block on the Bitcoin blockchain is 6.25 bitcoin. Miners can range from individual enthusiasts to professional mining operations with dedicated data centers. Miners may organize themselves in mining pools. We compete or may in the future compete with other companies that focus all or a portion of their activities on owning or operating digital asset exchanges, developing programming for the blockchain, and mining activities. Currently, the information concerning the activities of these enterprises is not readily available as the vast majority of the participants in this sector do not publish information publicly or the information may be unreliable.
While there is limited available information regarding non-public competitors, several public companies (traded in the United States and internationally), such as the following, may be considered to compete with us:
• Argo Blockchain plc;
• Bitfarms Ltd.;
• Bit Digital, Inc.;
• Cipher Mining Inc.;
• Cleanspark, Inc.;
• Core Scientific, Inc.;
• Greenidge Generation Holdings Inc.;
• Hive Digital Technologies Ltd.;
• Hut 8 Corp.;
• Iris Energy Limited;
• Riot Platforms, Inc.;
• Stronghold Digital Mining, Inc.; and
• TeraWulf Inc.
We believe our recent acquisition of two currently operational bitcoin mining sites, totaling 390 megawatts of capacity, in Granbury, Texas and Kearney, Nebraska and our ongoing deployment of miners positions us well among the publicly traded companies involved in the digital asset mining industry. The digital asset mining industry is a highly competitive and evolving industry and new competitors and/or emerging technologies could enter the market and affect our competitiveness in the future.
INTELLECTUAL PROPERTY
We actively use specific hardware and software for digital asset mining operations. In certain cases, source code and other software assets may be subject to an open-source license, as much of the technology development underway in our sector is open source.
We currently own five patents in the United States and have six patent applications pending. The expiration dates of our patents range from March 2036 and November 2043. Our patents improve efficiency to decrease settlement risk and expand server and radio functionalities. In the future, we may seek to register additional patents in connection with our existing and planned blockchain and digital asset operations.
We rely upon the following to protect and enforce our proprietary information and intellectual property:
12
Table of Contents
• trade secrets;
• trademarks;
• service marks;
• trade names;
• copyrights; and
• other intellectual property rights.
Additionally, we expect to license the use of intellectual property rights owned and controlled by others. We also have developed, and may further develop, certain proprietary software applications for purposes of its digital asset mining operation and may license proprietary software application to third parties.
REGULATORY LANDSCAPE
We operate within a complex and rapidly evolving regulatory environment and are subject to a wide range of laws and regulations enacted by U.S. federal, state, and local governments, governmental agencies, and regulatory authorities, including the SEC, the Commodity Futures Trading Commission (the “CFTC”), the Federal Trade Commission (the “FTC”), and the Financial Crimes Enforcement network of the U.S. Department of Treasury, as well as similar entities in other countries. Other regulatory bodies have demonstrated an interest in regulating or investigating companies engaged in blockchain or cryptocurrency businesses.
Regulations may substantially change in the future and it is presently not possible to know how regulations will apply to our business, or when they may be effective. While we anticipate that bitcoin mining will be an area of focus for regulators in 2024 and beyond, we cannot predict with certainty the impact regulations may have on our business or operations. As the regulatory and legal environment evolves, we may become subject to new laws and regulations by the SEC and other agencies, which may affect our mining operations and other activities. Additionally, state and local regulation of bitcoin mining is important with respect to where we conduct our mining operations. A substantial number of our bitcoin miners are located in Texas and North Dakota, which are generally favorable regulatory environments for bitcoin miners as compared to other states. However, we may also become subject to additional regulatory requirements on a state and local level in the geographies in which we operate, and as we strategically expand our operations into new areas.
For additional discussion regarding our belief about the potential risks existing and future regulation pose to our business, see Part I, Item 1A. “ Risk Factors ” of this Annual Report.
HUMAN CAPITAL AND DIVERSITY, EQUITY AND INCLUSION
As of December 31, 2023, we had a total workforce of approximately 60 employees across our entire organization, all of whom were employed full-time, including professionals in accounting, communications, engineering, finance, growth, human resources, information and technology, investor relations, legal, and operations.
Our strategy with human capital resources is to align the interests of our employees with our key long-term success drivers. In execution of this strategy, we adopted an equity incentive plan, under which all eligible employees can be granted options, restricted stock, preferred stock, restricted stock units or warrants. We believe our performance plan is a key incentive for our employees that aligns their long-term interests with our long-term objectives as an organization.
We also compare salary and wages against quantitative benchmarks and adjust monetary compensation to ensure wages are competitive and consistent with employee positions, skill levels, experience, and geographic location. We maintain a robust process for ensuring pay equity across the Company and increases in incentives and compensation based on merit and performance. In addition, we provide a comprehensive range of benefits options, including medical, dental and vision insurance for employees and family members, paid and unpaid leaves, and life and disability/accident coverage.
At Marathon, we seek to attract a pool of diverse, best-in-class candidates and foster their career growth by hiring the best talent available, rather than relying solely on educational background. In support of such initiative, we look for candidates in local communities and large cities alike, and from a variety of backgrounds. Our goal is a long-term, growth-oriented career for each employee. We also believe that our ability to retain our workforce is dependent on our ability to foster an environment that is sustainably safe, respectful, fair, and inclusive of everyone, and promotes diversity, equity, and inclusion both inside and outside of our business.

RECENT DEVELOPMENTS
On October 24, 2023, we commenced a new at-the-market offering program (the “2023 ATM”) with H.C. Wainwright & Co., LLC, acting as sales agent (“Wainwright”), pursuant to an at-the-market offering agreement (the “ATM Agreement”), under which we may offer and sell shares of our common stock from time to time through the sales agent having an aggregate offering price of up to $750.0 million. As of December 31, 2023, we sold 19,591,561 shares of common stock under the 2023 ATM for an aggregate purchase price of $248.1 million, net of commissions and expenses. Subsequent to December 31, 2023, we sold additional shares of common stock under the 2023 ATM such that the aggregate offering price of shares sold under the 2023 ATM is approximately $750.0 million. In February 2024, we intend to commence a new at-the-market offering program with Wainwright acting as sales agent (the “2024 ATM”) pursuant to the ATM Agreement, under which we may offer and sell shares of our common stock from time to time through Wainwright having an aggregate offering price of up to $1.5 billion.
On January 12, 2024, we consummated an acquisition of 100% of the issued and outstanding equity interests (the “Transaction”) of GC Data Center Equity Holdings, LLC, through our wholly owned subsidiary MARA USA Corporation, pursuant to which we acquired two operational bitcoin mining sites for an aggregate 390 megawatts of operational capacity in exchange for $179.0 million cash consideration, subject to customary working capital adjustments. We hope to realize synergies from this transaction through the integration of our technology stack, which we expect will improve efficiencies and scale our operating capacity.
In November 2023, we launched a joint venture in Paraguay with 1,170 miners energized. The operations at this facility are powered entirely by hydroelectricity. We expect operations at this facility to commence during the quarter ending June 30, 2024 and to generate 1.1 exahashes.
We completed the installation and energization of approximately 28,000 S19 XPs to commence operations at a Garden City, Texas site during the quarter ended December 31, 2023.
