2 FORWARD-LOOKING STATEMENTS 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, grow its business and execute on its growth plans and contractual commitments, source sufficient energy at attractive rates, the advantages, expected growth, and anticipated future revenue 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 facts. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially, including: our ability to attract customers for our high density colocation capabilities; our ability to perform under our existing colocation agreements, our ability to maintain our competitive position in our existing operating segments; 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; our vulnerability to physical security breaches, which could disrupt our operations; a potential slowdown in market and economic conditions, particularly those impacting high density computing; changing expectations with respect to ESG policies; the effectiveness of our compliance and risk management methods. 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. 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, 2024, Quarterly Reports on Form 10-Q and the Company’s other filings with the Securities and Exchange Commission.
