Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the United States Private Securities Litigation Reform Act of 1995 and forward-looking information within the meaning of applicable Canadian securities laws (collectively, “forward-looking statements”). Forward-looking statements may include, but are not limited to, statements regarding the Company’s expectations about the timing of filing the Form 10-Q and being in compliance with the Nasdaq listing rule within the timeframe prescribed by the Nasdaq notification letter. Forward-looking statements are typically identified by words such as “plan,” “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “continue,” “could,” “may,” “might,” “possible,” “potential,” “predict,” “should,” “would” and other similar words and expressions, but the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements are based on the current expectations of the management of the Company and are inherently subject to uncertainties and changes in circumstances and their potential effects and speak only as of the date of such statement. There can be no assurance that future developments will be those that have been anticipated. Forward-looking statements reflect material expectations and assumptions, including, without limitation, expectations, and assumptions relating to: the Company’s ability to complete its financial reporting and closing process for the quarterly period ended March 31, 2023 within the anticipated timeframe; and the ability of the Company to regain compliance with Nasdaq continued listing requirements. Such expectations and assumptions are inherently subject to uncertainties and contingencies regarding future events and,

as such, are subject to change. Forward-looking statements involve a number of risks, uncertainties or other factors that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those discussed and identified in public filings made by the Company with the SEC and the applicable Canadian securities regulatory authorities and the following: the Company being unable to complete its financial reporting and closing process for the quarterly period ended March 31, 2023 and the Company consequently not filing the Form 10-Q within the anticipated timeframe; and the Company’s inability to regain compliance with Nasdaq continued listing requirements and becoming subject to delisting from Nasdaq. Should one or more of these risks or uncertainties materialize or should any of the assumptions made by the management of the Company prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. All subsequent written and oral forward-looking statements concerning the matters addressed herein and attributable to the Company or any person acting on its behalf are expressly qualified in their entirety by the cautionary statements contained or referred to herein. Except to the extent required by applicable law or regulation, the Company undertakes no obligation to update these forward-looking statements to reflect events or circumstances after the date hereof to reflect the occurrence of unanticipated events.
