SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This report contains forward-looking statements, which are subject to safe harbor protection under the Private Securities Litigation Reform Act of 1995. All statements contained in this report other than statements of historical fact, including statements regarding our future financial condition and operating results, business strategy and plans, and objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “seek,” “plan,” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations, beliefs, and projections about future events, conditions, and trends that we believe may affect our financial condition, operating results, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties, assumptions, and changes in circumstances that are difficult to predict and many of which are outside of our control, such as those arising from the impact of recent macroeconomic events, including geopolitical instability, increased tariffs, elevated inflation, and fluctuating interest rates and foreign currency exchange rates, as well as those described in the “Risk Factors” section, which we encourage you to read carefully. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make.

In light of these risks, uncertainties, assumptions, and potential changes in circumstances, the future events, conditions, and trends discussed in this report may not occur and actual results could differ materially and adversely from those anticipated or implied by the forward-looking statements. Accordingly, you should not rely upon any forward-looking statements. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activities, performance, or achievements. We are under no duty to update any of these forward-looking statements after the date of this report or to conform these statements to actual results or revised expectations, except as required by applicable law. If we do update any forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.
