1 MAR 12, 2024 Fiscal Fourth Quarter and Full Year 2023 Earnings Presentation MARCH 12, 2024 Adam Sullivan, CEO Denise Sterling, CFO

2 MAR 12, 2024 This presentation contains “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, including but not limited to, statements regarding projections, estimates and forecasts of revenue and other financial and performance metrics, projections of market opportunity and expectations, the Company’s ability to scale and grow its business, source clean and renewable energy, the advantages and expected growth of the Company and the Company’s ability to source and retain talent. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “aim,” “estimate,” “plan,” “project,” “forecast,” “goal,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. All forward looking statements are subject to risks and uncertainties that may cause actual results to differ materially, including: our ability to earn digital assets profitably and to attract customers for our hosting capabilities; our ability to maintain our competitive position as digital asset networks experience increases in total network hash rate; our ability to raise additional capital to continue our expansion efforts or other operations; our need for significant electric power and the limited availability of power resources; the potential failure in our critical systems, facilities or services we provide; the physical risks and regulatory changes relating to climate change; potential significant changes to the method of validating blockchain transactions; our vulnerability to physical security breaches, which could disrupt our operations; a potential slowdown in market and economic conditions, particularly those impacting the blockchain industry and the blockchain hosting market; the identification of material weaknesses in our internal control over financial reporting; price volatility of digital assets and bitcoin in particular; the “halving” of rewards available on the Bitcoin network, or the reduction of rewards on other networks, affecting our ability to generate revenue as our customers may not have an adequate incentive to continue mining and customers may cease mining operations altogether; the potential that insufficient awards from digital asset mining could disincentivize transaction processors from expending processing power on a particular network, which could negatively impact the utility of the network and further reduce the value of its digital assets; the requirements of our existing debt agreements for us to sell our digital assets earned from mining as they are received, preventing us from recognizing any gain from appreciation in the value of the digital assets we hold; potential changes in the interpretive positions of the SEC or its staff with respect to digital asset mining firms; the increasing likelihood that U.S. federal and state legislatures and regulatory agencies will enact laws and regulations to regulate digital assets and digital asset intermediaries; increasing scrutiny and changing expectations with respect to our ESG policies; the effectiveness of our compliance and risk management methods; the adequacy of our sources of recovery if the digital assets held by us are lost, stolen or destroyed due to third-party digital asset services; the effects of our emergence from bankruptcy on our financial results, business and business relationships; and our substantial level of indebtedness and our current liquidity constraints affecting our financial condition and ability to service our indebtedness. Any such forward-looking statements represent management’s estimates and beliefs as of the date of this presentation. While we may elect to update such forward-looking statements at some point in the future, we disclaim any obligation to do so, even if subsequent events cause our views to change. Year over year comparisons are based on the combined results of Core Scientific and its acquired entities. Although the Company believes that in making such forward-looking statements its expectations are based upon reasonable assumptions, such statements may be influenced by factors that could cause actual outcomes and results to be materially different from those projected. The Company cannot assure you that the assumptions upon which these statements are based will prove to have been correct. Additional important factors that may affect the Company’s business, results of operations and financial position are described from time to time in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, Quarterly Reports on Form 10-Q and the Company’s other filings with the Securities and Exchange Commission. The Company does not undertake any obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as may be required by applicable law. Non-GAAP Financial Measures This presentation also contains non-GAAP financial measures as defined by the SEC rules, including Adjusted EBITDA and adjusted earnings (loss) per diluted share. The Company believes that these non- GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company's financial condition and results of operations. The Company's management uses certain of these non-GAAP measures to compare the Company's performance to that of prior periods for trend analyses and for budgeting and planning purposes. The Company urges investors not to rely on any single financial measure to evaluate its business. Forward-looking statements
