Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the securities laws. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include words or variation of words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “projects,” “forecasts,” “targets,” “would,” “will,” “should,” “goal,” “could” or “may” or other similar expressions. Forward-looking statements provide management’s or the Board’s current expectations or predictions of future conditions, events, or results. All statements that address operating performance, events, or developments that may occur in the future are forward-looking statements. All forward-looking statements speak only as of the date they are made and reflect the Company’s good faith beliefs, assumptions, and expectations, but they are not guarantees of future performance or events. Furthermore, the Company disclaims any obligation to publicly update or revise any forward-looking statement, except as required by law. By their nature, forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements. Factors that might cause such differences include, but are not limited to, a variety of economic, competitive, and regulatory factors, many of which are beyond the Company’s control, that are described in the Company’s periodic reports filed with the SEC including its Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and other factors that the Company may describe from time to time in other filings with the SEC. You should understand that it is not possible to predict or identify all such factors and, consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.
