Signed 20-year $6.6 billion triple-net lease at Sandersville with high investment-grade tenant

Ordered and pre-paid all long-lead items to meet Sandersville RFS date

Anticipated equity portion of Sandersville project has been fully funded

LAS VEGAS, Aug. 6, 2026 /PRNewswire/ -- CleanSpark, Inc. (NASDAQ:CLSK) ("CleanSpark" or the "Company"), a market leading data center developer, today reported financial results for the quarter ended June 30, 2026.

CleanSpark CEO and Chairman Matt Schultz commented, "We continue to successfully execute on our strategic evolution to a diversified digital infrastructure platform. Our recently announced Sandersville lease offers an ideal combination of long-term, durable cash flows and de-risked economic returns for our shareholders. We remain focused on the commercialization of our existing assets and the acquisition of scalable infrastructure to further bolster our portfolio."

"Capital stewardship remains central to how we allocate resources and evaluate growth," said Gary Vecchiarelli, President and CFO. "By fully funding our anticipated equity commitment for Sandersville and securing the long-lead equipment required to meet the project ready-for-service schedule, we have materially de-risked execution while preserving balance sheet flexibility. Despite currently challenging bitcoin mining economics, we have a portfolio of scarce, grid-connected power assets and multiple pathways to commercialization. We are positioned to convert infrastructure optionality into durable cash flows and long-term shareholder value."

In this press release, forward-looking statements include, but may not be limited to, statements regarding the Company's evolving business strategy to expand into the market for data center development, high-performance computing ("HPC"), and artificial intelligence ("AI"), and other statements regarding the Company's expectations, beliefs, plans, intentions, and strategies. In some cases, you can identify forward-looking statements by terms such as "may," "will," "should," "expects," "plans," "anticipates," "could," "intends," "targets," "projects," "contemplates," "believes," "estimates," "forecasts," "predicts," "potential" or "continue" or the negative of these terms or other similar expressions.

The forward-looking statements are subject to a variety of known and unknown risks, uncertainties, and other important factors that may cause our actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward-looking statements, including, but not limited to: the success of development and commercialization of some or all of our existing portfolio of bitcoin mining sites, as well as our other power and land assets, as data centers having operations other than bitcoin mining; identification and acquisition of new sites and power capacity capable of supporting data centers; risks related to data center construction and operations, including permitting and utility constraints, construction delays, cost overruns, financing and supply-chain challenges, tenant performance, and the possibility projects may not be completed, delivered or operated on the anticipated timeline, budget or terms; the success of the Company's bitcoin mining activities; the volatile and unpredictable cycles in the emerging and evolving industries in which the Company operates, including the volatility of BTC prices; increasing difficulty rates for bitcoin mining; bitcoin halving; changes to compute and data center infrastructure; new or additional governmental regulation; dependency on utility rate structures and government incentive programs; dependency on third-party power providers for expansion efforts; the expectations of future revenue growth may not be realized, including in respect of the data center development, leasing, and compute markets; and other risks described in the Company's prior press releases and in its filings with the Securities and Exchange Commission (SEC), including under the heading "Risk Factors" in those filings.

Non-GAAP Measure

We present Adjusted EBITDA, which is not a measurement of financial performance under GAAP. Our non-GAAP "Adjusted EBITDA" excludes (i) impacts of interest, taxes, and depreciation; (ii) our share-based compensation expense, unrealized gains/losses on securities, and changes in the fair value of contingent consideration with respect to previously completed acquisitions, all of which are 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) non-cash impairment losses related to long-lived assets; (iv) realized gains and losses on sales of equity securities, the amounts of which are directly related to the unrealized gains and losses that are also excluded; (v) legal fees related to litigation and various transactions, which fees management does not believe are reflective of our ongoing operating activities; (vi) gains and losses on disposal of assets, the majority of which are related to obsolete or unrepairable machines that are no longer deployed; (vii) gains and losses related to discontinued operations that would not be applicable to our future business activities; and (viii) severance expenses.

Management believes that providing this non-GAAP financial measure that excludes these items allows for meaningful comparisons between the Company's core business operating results and those of other companies, and provides 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. In addition to management's internal use of non-GAAP Adjusted EBITDA, management believes that Adjusted EBITDA is also useful to investors and analysts in comparing our performance across reporting periods on a consistent basis. Management believes the foregoing to be the case even though some of the excluded items involve cash outlays and some of them recur on a regular basis (although management does not believe any of such items are normal operating expenses necessary to generate our bitcoin-related revenues). 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.

The Company's Adjusted EBITDA measure may not be directly comparable to similar measures provided by other companies in our industry, as other companies in our industry may calculate non-GAAP financial results differently. The Company's Adjusted EBITDA is not a measurement of financial performance under GAAP and should not be considered as an alternative to operating (loss) income or any other measure of performance derived in accordance with GAAP. Although management utilizes internally and presents Adjusted EBITDA, we only utilize that measure supplementally and do not consider it to be a substitute for, or superior to, the information provided by GAAP financial results.

Accordingly, Adjusted EBITDA is not meant to be considered in isolation of, and should be read in conjunction with, the information contained in our Condensed Consolidated Financial Statements, which have been prepared in accordance with GAAP.
