Physical gold is only divisible into small pieces; Bitcoin is divisible to eight decimals. Gold and bitcoin are fungible, but fiat currency is not fungible with oth er fiat (US Dollar is not fungible with the Canadian Dollar). Gold has a high value-to- weight ratio, but it is still heavy and cumbersome to transport compared to the others. Both gold and fiat currency have been counterfeited; Gold can be verified but only through cumbersome assay. Gold is scarce, bitcoin is scarce and finite; The only constraint on fiat currency is willingness of government or central bank. Gold has the longest track record of money and maintaining purchasing power; Bitcoin's history is the shortest; Fiat currency has a poor track record. All Rights Reserved.

It sits on six acres near the Hartsfield-Jackson Atlanta International Airport and features at its heart 48 new generation air-cooled pods enclosed by a Department of Transportation sound wall. Machines are also housed in 20 Ant boxes, an annex building and within the original data center. CleanSpark founder and CEO Zach Bradford originally visited the operation to consult on an energy project but quickly recognized the opportunity to lead one of the most important energy projects of our generation: bitcoin mining.

Situated on over seven acres, the immersion- cooled site participates in Georgia's Flex REC program and is 100% net carbon-neutral. There are two large rooms that house 20 MW of single-phase immersion ― about 4,300 machines. Liquid immersion cooling, where the bitcoin mining machines are fully immersed in a specialized oil, has proven to significantly improve efficiency by reducing power consumption and extending the life of the machines — thereby maximizing financial gains.

It was purchased during the summer 2022 bear market from another bitcoin miner as an already-operational site. Bitcoin mining machines operate in multiple air-cooled buildings. A completed 50MW expansion created four more buildings filled with an additional 14,000 latest-gen miners. It draws power predominantly from low-carbon sources, such as nuclear energy. Since its acquisition, CleanSpark has contributed hundreds of thousands in taxes to the city and supported numerous local businesses through sponsorships and charities. It is a perfect place to mine bitcoin, and we are thrilled to partner with the community. 98.83% Uptime 1,176,120 Square Footage MEAG Utility Provider NASDAQ: CLSK All Rights Reserved.

The turnkey operation in Sandersville was acquired from another bitcoin miner with room to almost triple its capacity. The site is undergoing a massive 150 MW expansion with expected completion later this year. It will feature cathedral-style buildings, some the length of over three football fields. Each building will house thousands of high-performance bitcoin mining machines and, once completed, will add about 7 EH/s to CleanSpark's hashrate.

PARTNERED JULY 2021 CO- LOCATED AIR-COOLED SYSTEM Copyright 2023 CleanSpark | 37#38Non-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.
