GLOSSARY OF TERMS AND CONCEPTS

This Quarterly Report includes a number of terms and concepts which are defined as follows:

•AI Cloud Services: platforms that provide access to AI/ML capabilities through cloud-based infrastructure.

•AI/ML: Artificial Intelligence and Machine Learning. Artificial Intelligence (“AI”) is computer software that mimics human cognitive abilities in order to perform complex tasks, such as decision making, data analysis, language translation and a variety of tools and services across the emergent AI industry that have been developed to leverage AI capabilities. Machine Learning (“ML”) is a subset of AI in which algorithms are trained on data sets to become machine learning models capable of performing specific tasks.

•ASICs: An Application Specific Integrated Circuit is a type of integrated circuit that is custom-designed for a particular use, rather than intended for general-purpose use.

•Bitcoin: A system of global, decentralized, scarce, digital money as initially introduced in a white paper titled Bitcoin: A Peer-to-Peer Electronic Cash System by Satoshi Nakamoto.

•Bitcoin network: The collection of all nodes running the Bitcoin protocol. This includes miners that use computing power to maintain the ledger and add new blocks to the blockchain.

•block: A bundle of transactions analogous with digital pages in a ledger. Transactions are bundled into blocks, which are then added to the ledger. Miners are rewarded for “mining” a new block.

•blockchain: A software program containing a cryptographically secure digital ledger that maintains a record of all transactions that occur on the network, that enables peer-to-peer transmission of transaction information, and that follows a consensus protocol for confirming new blocks to be added to the blockchain.

•Board: The board of directors of the Company.

•Co-Founders and Co-Chief Executive Officers: Daniel Roberts and William Roberts.

•cryptocurrency or digital asset: Bitcoin and alternative coins, or “altcoins,” launched after the success of Bitcoin. This category is designed to serve functions including as a medium of exchange, store of value, and/or to power applications.

•difficulty: In the context of Bitcoin mining, a measure of the relative complexity of the algorithmic solution required for a miner to mine a block and receive the Bitcoin reward. An increase in global hashrate will temporarily result in faster block times as the mining algorithm is solved quicker - and vice versa if the global hashrate decreases. The Bitcoin network protocol adjusts the network difficulty every 2,016 blocks (approximately every two weeks) to maintain a target block time of 10 minutes.

•EH/s: Exahash per second. 1 EH/s equals one quintillion hashes per second (1,000,000,000,000,000,000 h/s).

•fiat currency: A government issued currency that is not backed by a physical commodity, such as gold or silver, but rather by the government that issued it.

•GPUs: Graphics processing units are a type of computing technology designed for parallel processing, which can be used in a wide range of applications, including graphics and video rendering, gaming, creative production and AI.

•hash: To compute a function that takes an input, and then outputs an alphanumeric string known as the “hash value.”

•hashrate: The speed at which a miner can produce computations (hashes) using the Bitcoin network’s algorithm, expressed in hashes per second. The hashrate of all miners on a particular network is referred to as the global hashrate.

•HPC: High-performance computing, which refers to the aggregation of computing power to achieve higher performance levels, often utilized to perform complex calculations in fields including science, engineering, finance, AI/ML, and business. It typically involves using supercomputers or clusters of computers, often employing parallel processing, to perform calculations simultaneously, thereby greatly reducing computation time.

•miner: Individuals or entities who operate a computer or group of computers that compete to mine blocks. Bitcoin miners who successfully mine blocks are rewarded with new Bitcoin as well as any transaction fees.

•mining: The process by which new Bitcoin blocks are created, and thus new transactions are added to the blockchain in the Bitcoin network.

•mining pools: Mining pools are platforms for miners to contribute their hashrate in exchange for digital assets, including Bitcoin, and in some cases regardless of whether the pool effectively mines any block. Miners tend to join pools to increase payout frequency, with pools generally offering daily payouts, and to externalize to the pool the risk of a block taking longer than statistically expected from the network difficulty. Mining pools offers these services in exchange for a fee.

•MW: Megawatts. 1MW equals 1,000 kilowatts.
