This press release contains certain forward-looking statements within the meaning of the federal securities laws of the United States. The Company intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and includes this statement for purposes of complying with these safe harbor provisions. Any statements made in this press release that are not statements of historical fact, such as statements about the Company’s beliefs and expectations regarding its planned business model and strategy, its data center development, timing and likelihood of success, capacity, functionality and operation of data centers, expectations regarding the operations of data centers, potential strategic initiatives, such as joint ventures and partnerships, and management plans and objectives, are forward-looking statements and should be evaluated as such. These forward-looking statements generally are identified by the words “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “seeks,” “intends,” “targets,” “projects,” “contemplates,” “believes,” “estimates,” “strategy,” “future,” “forecasts,” “opportunity,” “predicts,” “potential,” “would,” “will likely result,” “continue,” and similar expressions (including the negative versions of such words or expressions).
These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by Cipher and its management, are inherently uncertain. Such forward-looking statements are subject to risks, uncertainties, and other factors that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this press release, including but not limited to: volatility in the price of Cipher’s securities due to a variety of factors, including changes in the competitive and regulated industry in which Cipher operates, Cipher’s evolving business model and strategy and efforts it may make to modify aspects of its business model or engage in various strategic initiatives, variations in performance across competitors, changes in laws and regulations affecting Cipher’s business, and the ability to implement business plans, forecasts, and other expectations and to identify and realize additional opportunities. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of Cipher’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the Securities and Exchange Commission (“SEC”) on February 25, 2025, Cipher’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025 filed with the SEC on August 7, 2025, Cipher’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2025 filed with the SEC on November 3, 2025, and in Cipher’s subsequent filings with the SEC.

Non-GAAP Financial Measures
This press release includes a supplemental financial measure for Net Operating Income (NOI) Margin, which the Company defines as follows: NOI Margin represents rental revenue less rental property operating expenses, property taxes and insurance expenses (as recorded in the Company’s consolidated statements of operations) divided by rental revenue. NOI Margin is commonly used by stockholders, the Company’s management and industry analysts as a measurement of operating performance of the Company’s rental portfolio. However, because NOI Margin excludes depreciation and amortization and captures neither the changes in the value of the Company’s data centers that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of the Company’s data centers, all of which have real economic effect and could materially impact the Company’s consolidated results of operations, the utility of NOI Margin as a measure of the Company’s performance is limited. Other companies, including Real Estate Investment Trusts, may calculate NOI Margin differently than we do and, accordingly, our NOI Margin may not be comparable to these companies’ NOI Margin. This supplemental financial measure is not a measurement of financial performance under accounting principles generally accepted in the United States (“GAAP”) and, as a result, this supplemental financial measure may not be comparable to similarly titled measures of other companies. Management uses this non-GAAP financial measure internally to help understand, manage, and evaluate our business performance and to help make operating decisions. We believe the use of this non-GAAP financial measure can also facilitate comparison of our operating results to those of our competitors by excluding certain items that vary in our industry based on company policy.
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, we expect that share-based compensation expense, which is excluded from the non-GAAP financial measure, 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. Similarly, we expect that depreciation and amortization will continue to be a recurring expense over the term of the useful life of the related assets. Our non-GAAP financial measures are not meant to be considered in isolation and should be read only in conjunction with our condensed consolidated financial statements included elsewhere in this press release, which have been prepared in accordance with GAAP. We rely primarily on such condensed consolidated financial statements to understand, manage and evaluate our business performance and use the non-GAAP financial measures only supplementally.
