“Atomera’s strong benefits for power devices, RF products and advanced nodes devices have been confirmed through extensive testing and modeling, and our customers and partners are now seeing the data as our staff has been able to visit more customers in person over this last quarter,” said Scott Bibaud, President and CEO. “We have expanded our pipeline for future JDA customers, while our current JDA partner made progress toward production. We are confident we can help customers gain competitive advantages as the industry starts to exit this period of tight fab capacity and supply shortages, and enters a stage of robust investment in new production technologies and equipment.”

Note about Non-GAAP 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 non-GAAP financial measure. Adjusted EBITDA is determined by taking net loss and eliminating the impacts of interest, depreciation, amortization and stock-based compensation. Our definition of adjusted EBITDA may not be comparable to the definitions of similarly-titled measures used by other companies. We believe that this non-GAAP financial measure, viewed in addition to and not in lieu of our 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.

Safe Harbor

This press release contains forward-looking statements concerning Atomera Incorporated, including statements regarding the prospects for the semiconductor industry generally and the ability of our MST technology to significantly improve semiconductor performance. Those forward-looking statements involve known and unknown risks, uncertainties and other factors that could cause actual results to differ materially. Among those factors are: (1) the fact that, to date, we have only recognized minimal engineering services and licensing revenues and we have not yet commenced principal revenue producing operations or entered into a definitive royalty-based manufacturing and distribution license agreement with regard to our MST technology, thus subjecting us to all of the risks inherent in an early-stage enterprise; (2) risks related our ability to successfully complete the milestones in our joint development agreement or, even if successfully completed, to reach a commercial distribution license with our JDA customer; (3) risks related to our ability to advance the licensing arrangements with our initial integration licensees, Asahi Kasei Microdevices, ST Microelectronics and our fabless licensee, to royalty-based manufacturing and distribution licenses or our ability to add other licensees; (4) risks related to our ability to raise sufficient capital, as and when needed, to pursue the further development, licensing and commercialization of our MST technology; (5) our ability to protect our proprietary technology, trade secrets and knowhow and (6) those other risks disclosed in the section "Risk Factors" included in our Annual Report on Form 10-K filed with the SEC on February 19, 2021. We caution readers not to place undue reliance on any forward-looking statements. We do not undertake, and specifically disclaim any obligation, to update or revise such statements to reflect new circumstances or unanticipated events as they occur.
