v What is Bitcoin Mining? A bitcoin mining company uses specialized computers to verify transactions on the bitcoin blockchain. Bitcoin is the reward miners earn for performing this service. Without mining, there would be no bitcoin. Mining is energy intensive, so maintaining this increasingly important component of our digital infrastructure requires wise stewardship of our resources. We draw on our energy technology background to mine bitcoin in a responsible way. Since mining our very first bitcoin, we’ve used a sustainable energy mix that includes nuclear, hydroelectric, solar, and wind. We purchase renewable energy credits to account for differences in regional energy mixes to achieve our goal of 100% net carbon neutrality.

Bitcoin wallet transaction CleanSpark & other decentralized miners support the network by verifying and securing transactions.  Bitcoin wallet transaction What Do Miners Do?

What are Block Rewards? 21,000,000 BTC mined by 2140 Block rewards are reduced by half every 210,000 blocks (roughly every four years) until all 21M bitcoin are mined. When will that be? Sometime around 2140. 1 block every 10 min. 2140 2024 6.25 BTC per block 900 BTC per day Today

Vision:  Top North American Bitcoin Miner Hashrate Our total computational power; when understood in the context of global hashrate, it determines how much bitcoin we are able to mine. Efficiency We determine efficiency by starting with our power costs and dividing it by our hashrate. Efficient miners produce more bitcoin while using fewer resources. Profitability Revenue, Net Income, and Adjusted EBITDA are metrics we use to evaluate our operating leverage. Sustainability We target energy sources that are primarily renewable & carbon-free; we participate in local renewable energy credit programs to offset any non-renewable sources of energy. Metrics That Matter

How We Allocate Opportunity Current mix: 3/4th owned-and-operated  Hybrid approach of using co-location partnerships for scalability and wholly-owned locations to secure our future Infrastructure first; we balance how & when we acquire machines ASIC ecosystem is ripe for disruption—faster, better, newer technologies are on the horizon How We Acquire Hardware Current Mix How We Evaluate Sites Our growth philosophy takes into account the power source, the cost of power, and the cost of the facility We also take into consideration our potential community impact We partner with the communities we operate in and work to earn their trust. Whether building our own facilities or choosing partners to host our machines, we make a positive impact on local economies by developing underused infrastructure and creating new job opportunities.  Build the Infrastructure of the Future

We use capital transparently because securing the bitcoin blockchain is a privilege and a responsibility we take to heart. Bitcoin is a store of value and medium of exchange. We combine it with the wise stewardship of our equity and the responsible deployment of debt to grow our business in the best way possible—for our employees, our shareholders, and the bitcoin community. Value Growth for the Greater Good Bitcoin is our currency: we think it makes sense to sell bitcoin to generate more bitcoin Our approach to HODLing is strategic and our HODL balance will vary - a 100% HODL is not sustainable and comes at a cost to shareholders We expect our bitcoin holdings to incrementally increase over time We intend to offer various tools when issuing  equity for growth capital and acquisitions, not to fund daily operations Utilizing equity allows us to be nimble and quickly capitalize on accretive opportunities in the marketplace We expect with continued profitability to return capital to shareholders, including, but not limited to, stock buybacks or dividends We expect to apply "smart leverage" on our balance sheet to obtain affordable capital Finalized $35 million facility from Trinity Capital in April 2022 Growth plans will be accelerated with expansion of debt capital Equity Bitcoin Debt

Non-GAAP Measures Adjusted EBITDA is not a measurement of financial performance under generally accepted accounting principles in the United States (“GAAP”). Because of varying available valuation methodologies, subjective assumptions and the variety of equity instruments that can impact a company's non-cash operating expenses, CleanSpark management believes that providing a non-GAAP financial measure that excludes non-cash and non-recurring expenses allows for meaningful comparisons between the Company's core business operating results and those of other companies, as well as providing the Company with an important tool for financial and operational decision making and for evaluating its own core business operating results over different periods of time. The Company's Adjusted EBITDA measure may not provide information that is directly comparable to that provided by other companies in its industry, as other companies in its industry may calculate non-GAAP financial results differently, particularly related to non-recurring, unusual items. The Company's Adjusted EBITDA is not a measurement of financial performance under GAAP and should not be considered as an alternative to operating income or as an indication of operating performance or any other measure of performance derived in accordance with GAAP. Our management does not consider Adjusted EBITDA to be a substitute for, or superior to, the information provided by GAAP financial results. We are providing supplemental financial measures for non-GAAP adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) that excludes the impact of interest, taxes, depreciation, amortization, our share-based compensation expense, and impairment of assets, unrealized gains/losses on securities, certain financing costs, other non-cash items, certain non-recurring expenses, and impacts related to discontinued operations. These supplemental financial measures are not measurements of financial performance under GAAP and, as a result, these supplemental financial measures may not be comparable to similarly titled measures of other companies. Management uses these non-GAAP financial measures internally to help understand, manage, and evaluate our business performance and to help make operating decisions. We believe that these non-GAAP financial measures are also useful to investors and analysts in comparing our performance across reporting periods on a consistent basis. Adjusted EBITDA excludes (i) impacts of interest, taxes, and depreciation; (ii) significant non-cash expenses such as our share-based compensation expense, unrealized gains/losses on securities, certain financing costs, other non-cash items that we believe are not reflective of our general business performance, and for which the accounting requires management judgment, and the resulting expenses could vary significantly in comparison to other companies; (iii) significant impairment losses related to long-lived and digital assets, which include our bitcoin for which the accounting requires significant estimates and judgment, and the resulting expenses could vary significantly in comparison to other companies; and (iv) and impacts related to discontinued operations that would not be applicable to our future business activities. Non-GAAP financial measures are subject to material limitations as they are not in accordance with, or a substitute for, measurements prepared in accordance with GAAP. For example, we expect that share-based compensation expense, which is excluded from Adjusted EBITDA, will continue to be a significant recurring expense over the coming years and is an important part of the compensation provided to certain employees, officers, and directors. We have also excluded impairment losses on assets, including impairments of our digital currency our non-GAAP financial measures, which may continue to occur in future periods as a result of our continued holdings of significant amounts of bitcoin. Our non-GAAP financial measures are not meant to be considered in isolation and should be read only in conjunction with our Consolidated Financial Statements, which have been prepared in accordance with GAAP. We rely primarily on such Consolidated Financial Statements to understand, manage, and evaluate our business performance and use the non-GAAP financial measures only supplementally.
