Cautionary Note Regarding Forward-Looking Statements

This report contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Section 27A of the Securities Act of 1933, as amended (the “Securities Act”). Any statements contained in this Annual Report on Form 10-Kthat are not statements of historical fact may be forward-looking statements. When we use the words “anticipates,” “plans,” “estimates,” “expects,” “believes,” “should,” “could,” “may,” “will” and similar expressions, we are identifying forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future financial events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. Forward-looking statements involve risks and uncertainties described under “Risk Factors” in Part I, Item 1A, and elsewhere in this Annual Report on Form 10-K, and may include statements related to, among other things: macroeconomic factors, including inflationary pressures, supply shortages and recessionary pressures; impact of tariffs on sourcing of raw materials; accounting estimates and assumptions; pricing pressures on our product caused by competition; the risk that our products will not gain market acceptance; our ability to obtain additional financing; our ability to successfully prevent our registration with the U.S. Securities and Exchange Commission (the “SEC”) from being suspended or revoked; our ability to operate our accounting systems effectively; our ability to protect intellectual property; our ability to integrate our Pennsylvania facility into our operations; and our ability to attract and retain key employees. No forward-looking statement is a guarantee of future performance and you should not place undue reliance on any forward-looking statement. Our actual results may differ materially from those projected in forward-looking statements, as they will depend on many factors about which we are unsure, including many factors beyond our control.

Except as may be required by applicable law, we do not undertake or intend to update or revise our forward-looking statements, and we assume no obligation to update forward-looking statements contained in this report as a result of new information or future events or developments. Thus, you should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements. You should carefully review and consider the various disclosures we make in this report and our other reports filed with the SEC that attempt to advise interested parties of the risks, uncertainties and other factors that may affect our business.

Important factors that could cause actual results to differ materially from the results and events anticipated or implied by such forward-looking statements include, but are not limited to:
