Note about NonGAAP Financial Measures

In addition to the unaudited results presented in accordance with generally accepted accounting principles, or GAAP, in this press release, Atomera presents adjusted EBITDA, which is a nonGAAP financial measure. Adjusted EBITDA is determined by taking net loss and eliminating the impacts of interest, taxes, depreciation, amortization, stockbased compensation, the change in fair value of derivative liabilities, and the gain on the extinguishment of debt. Our definition of adjusted EBITDA may not be comparable to the definitions of similarlytitled measures used by other companies. We believe that this nonGAAP financial measure, viewed in addition to and not in lieu of its reported GAAP results, provides useful information to investors by providing a more focused measure of operating results. This metric is used as part of the Company's internal reporting to evaluate its operations and the performance of senior management. A table reconciling this measure to the comparable GAAP measure is available in the accompanying financial tables below.
