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, including statements about our beliefs and expectations regarding our future results of operations and financial position, business strategy, timing and likelihood of success, potential expansion of bitcoin mining data centers, and management plans and objectives, are forward-looking statements and should be evaluated as such. Forward-looking statements include information concerning possible or assumed future results of operations, including descriptions of our business plan and strategies. These forward-looking statements generally are identified by the words “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “seeks,” “intends,” “targets,” “projects,” “contemplates,” “believes,” “estimates,” “forecasts,” “predicts,” “potential” or “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 our 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

The foregoing list of factors is not exhaustive.

Non-GAAP Financial Measures

We use non-GAAP financial measures to assess and analyze our operational results and trends and to make financial and operational decisions. We believe these non-GAAP financial measures are useful to investors because they provide greater transparency regarding our operating performance. The non-GAAP financial measures included in this press release should not be considered alternatives to measurements required by GAAP, and should not be considered measures of liquidity. These non-GAAP financial measures are unlikely to be comparable with non-GAAP information provided by other companies. Reconciliation of non-GAAP financial measures and GAAP financial measures are included in the tables accompanying this press release. Reported results are presented in accordance with GAAP, whereas adjusted results are GAAP results adjusted to exclude the impact of (i) depreciation of fixed assets, (ii) change in fair value of warrant liability, (iii) non-cash change in fair value of our derivative asset and (iv) stock compensation expense.
