Forward-looking statements may include estimates or expectations about the Company’s possible or assumed operational results, financial condition, business strategies and plans, market opportunities, competitive position, industry environment, and potential growth opportunities. In some cases, forward-looking statements can be identified by terms such as “may,” “will,” “should,” “design,” “target,” “aim,” “hope,” “expect,” “could,” “intend,” “plan,” “anticipate,” “estimate,” “believe,” “continue,” “predict,” “project,” “potential,” “goal,” or other words that convey the uncertainty of future events or outcomes. These statements relate to future events or to the Company’s future financial performance, and involve known and unknown risks, uncertainties and other factors that may cause the Company’s actual results, levels of activity, performance, or achievements to be different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements. All statements contained in this press release that do not relate to matters of historical fact should be considered forward-looking statements, including, but not limited to, statements regarding the Company’s belief that it will meet the net income standard set forth in Nasdaq Listing Rule 5550(b)(3).

The Company’s actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, including the risk that the Company may not timely file its Annual Report on Form 20-F for the year ended December 31, 2022, the risk that the Company may not otherwise timely evidence its compliance with the applicable Nasdaq listing requirement for continued listing, or at all, and the risk that Nasdaq may not ultimately grant the Company relief from delisting, among other risks and uncertainties.

Any forward-looking statement reflects the Company’s current views with respect to future events and is subject to these and other risks, uncertainties and assumptions relating to the Company’s operations, results of operations, growth strategy and liquidity. The Company assumes no obligation to publicly update or revise these forward-looking statements for any reason, or to update the reasons actual results could differ from those anticipated in these forward-looking statements, even if new information becomes available in the future.
