CleanSpark Reports Fourth Quarter and Year End FY2022 Financial Results

2022 Revenue of $131.5 million, net loss of $(57.3) million and Adjusted EBITDA of $65.7 million

Q4 revenue of $26.2 million, net loss of $(42.3) million and Adjusted EBITDA of $2.9 million

Current hashrate surpasses 5.8 EH/s and daily mining high reaches 21.7 BTC

LAS VEGAS—CleanSpark, Inc. (Nasdaq: CLSK) (the "Company"), America's Bitcoin Miner™, today reported financial results for the three and twelve months ended September 30, 2022.

“Our business model and capital strategy continue to be standouts in our industry,” said Zach Bradford, CEO. “Despite macro headwinds in the economy and bitcoin mining industry, our infrastructure first approach and financial discipline have allowed us to grow in this bear market. We continue to execute our business plans with best-in-class efficient mining operations and by identifying potential accretive acquisitions while maintaining very little leverage on our balance sheet. This team continues to exceed my expectations and I’m so proud of them.”

“This is a world class team that has doubled, tripled and even quadrupled multiple key performance indicators this fiscal year,” said Gary A. Vecchiarelli, CFO. “Our revenue for fiscal year 2022, which ended on September 30, was $131.5M, almost a 250% increase over the prior year. However, we recognized a net loss of $57.3M for the year, of which $42.3M occurred in the fourth quarter. The majority of these fourth quarter losses were primarily due to impairment of goodwill and bitcoin balances, as well as non-cash charges due to modification of equity instruments. Even then, our adjusted EBITDA was $65.7M, a 500% increase over the prior year, which represents the power and scale of our business model. Our rapid growth has continued subsequent to our fiscal year end as we approach 6.0 EH/s, exceeding our calendar year end guidance once again. We have four impressive sites that we own 100% with no partners and little debt, which resulted in mining 3,750 bitcoins, a 320% increase in production for the fiscal year.”

2023 Outlook and Commentary

Management will discuss plans for 2023, including a revision to its calendar 2023 year-end guidance, on its conference call today. Earlier this year, the Company announced a partnership with Lancium. As part of the agreement, Lancium agreed to build clean campuses in west Texas to host 200 MW, or about 6.6 EH/s. Lancium informed CleanSpark that capital constraints have affected their ability to meet their commitments. Expected completion dates have been pushed into late 2023 and, based on current market conditions, perhaps even later. For this reason, CleanSpark’s management team is revising 2023 calendar year-end guidance to 16 EH/s.

Non-GAAP Measure

The Company presents Adjusted EBITDA, which 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, the Company’s 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’s management with an important tool for financial and operational decision making and for evaluating its own core business operating results over different periods of time. In addition to management’s internal use of non-GAAP Adjusted EBITDA, the Company believes that this non-GAAP financial measure is also useful to investors and analysts in comparing the Company’s performance across reporting periods on a consistent basis.

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

To be filed: Tuesday, December 14, 1:00 p.m. PST/4:00 p.m. EST

under GAAP and should not be considered as an alternative to operating income (loss) or as an indication of operating performance or any other measure of performance derived in accordance with GAAP. The Company’s management does not consider Adjusted EBITDA to be a substitute for, or superior to, the information provided by GAAP financial results.

The Company’s non-GAAP “Adjusted EBITDA” represents earnings before interest, taxes, depreciation and amortization that excludes (i) impacts of interest, taxes, and depreciation; (ii) significant non-cash expenses such as share-based compensation expense, unrealized gains/losses on securities, certain financing costs, other non-cash items that the Company believes are not reflective of its general business performance, and for which the accounting requires management judgment, and the resulting expenses could vary significantly in comparison to other companies; (iii) impairment losses related to long-lived and digital assets, which include the Company’s 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 the Company’s 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, The Company expects 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.

The Company has also excluded impairment losses on assets, including impairments of its bitcoin in its non-GAAP financial measures, which may continue to occur in future periods as a result of the Company’s continued holdings of significant amounts of bitcoin. The Company’s non-GAAP financial measures are not meant to be considered in isolation and should be read only in conjunction with the Company’s Consolidated Financial Statements, which have been prepared in accordance with GAAP. The Company relies primarily on such Consolidated Financial Statements to understand, manage, and evaluate its business performance and uses the non-GAAP financial measures only supplementally.

See below for a reconciliation of non-GAAP Adjusted EBITDA to the most directly comparable performance measure presented in accordance with GAAP (i.e., net loss).
