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.

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. Additionally, management does not consider any of the excluded items to be expenses necessary to generate our bitcoin-related revenue.

While this renders energy prices less predictable, it also gives us greater ability and flexibility to actively manage the energy we consume with a goal of increasing profitability and energy efficiency. Energy prices are also highly sensitive to weather events, such as winter storms, polar vortices and hurricanes, which increase the demand for power regionally.
Such prices are governed by power purchase agreements which vary by location, and said prices can change hour to hour. While this renders energy prices less predictable, it also gives us greater ability and flexibility to actively manage the energy we consume with a goal of increasing profitability and energy efficiency.
