Doubled MW under contract year-over-year including 585 MW of ERCOT-approved capacity

Increased Bitcoin holdings by 14% and average monthly hashrate by 18% year-over-year

LAS VEGAS, May 11, 2026 /PRNewswire/ -- CleanSpark, Inc. (NASDAQ:CLSK) ("CleanSpark" or the "Company"), today reported financial results for the quarter ended March 31, 2026.

"This quarter, we accelerated our digital infrastructure evolution across four key areas: land and power development, with ERCOT approval of 300 MW in Brazoria; leasing, with further progress in Georgia and beyond; financing, as market conditions remain constructive; and construction, as we continue developing the new parcel in Sandersville," said Matt Schultz, CEO and Chairman of CleanSpark. "Our objectives are clear: commercialize our AI/HPC-applicable assets, grow the portfolio, and continue mining efficiently to power CleanSpark's transformation."

"Our balance sheet remains a core competitive advantage as we execute CleanSpark's growth strategy," said Gary Vecchiarelli, President and CFO. "We ended the quarter in a strong liquidity position that not only supports our near-term execution pipeline but also preserves meaningful optionality as the AI/HPC and digital infrastructure landscape continues to evolve. Our ability to move quickly and decisively on power and land expansion opportunities, as well as potential site commercialization initiatives, is a direct result of the financial discipline we have maintained. We believe we are well positioned to allocate capital dynamically, capitalize on emerging infrastructure opportunities, and continue creating 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 high-performance computing ("HPC") and artificial intelligence ("AI") and other expectations, beliefs, plans, intentions, and strategies, including the benefits of the Company's treasury management activities. 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 risk that the electrical power available to the Company's facilities does not increase as expected; 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; our ability to execute on our business strategy, including our ability to diversify and expand into the market for HPC and AI solutions and data centers; our limited experience with respect to new markets we are entering, including the market for HPC and AI services; our ability to compete with our new HPC and AI services competitors; new or additional governmental regulation; the impacts of evolving global and U.S. trade policies and tariff regimes, including that there is uncertainty as to whether the Company will face materially increased tariff liability in respect of miners purchased since 2024 and in the future; the Company's ability to successfully complete acquisitions, including integration risks relating to completed and potential acquisitions and the ability to successfully deploy new miners; 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 new markets that the Company seeks to enter; 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

The Company presents 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.
