CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Form 6-K Report and the exhibits hereto contain certain forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve known and unknown risks and uncertainties and are based on the Company’s current expectations and projections about future events that the Company believes may affect its financial condition, results of operations, business strategy and financial needs. Investors can identify these forward-looking statements by words or phrases such as “approximates,” “assesses,” “believes,” “hopes,” “expects,” “anticipates,” “estimates,” “projects,” “intends,” “plans,” “will,” “would,” “should,” “could,” “may” or similar expressions.

Many of these statements are based on our assumptions about factors that are beyond our ability to control or predict and are subject to significant risks and uncertainties that are described more fully in “Item 3. Key Information—D. Risk Factors” on our annual report on Form 20-F filed with the SEC on February 14, 2025. Any of these factors or a combination of these factors could materially affect our future results of operations and the ultimate accuracy of the forward-looking statements. Fluctuations in our future financial results may negatively impact the value of our Class A ordinary shares. In addition to these important factors, important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include, among other things:

Should one or more of the foregoing risks or uncertainties materialize, should any of our assumptions prove incorrect, or should we be unable to address any of the foregoing factors, our actual results may vary in material and adverse respects from those projected in these forward-looking statements. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects, on us. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements.

The Company undertakes no obligation to update or revise publicly any forward-looking statements to reflect subsequent occurring events or circumstances, or changes in its expectations, except as may be required by law. Although the Company believes that the expectations expressed in these forward-looking statements are reasonable, it cannot assure you that such expectations will turn out to be correct, and the Company cautions investors that actual results may differ materially from the anticipated results and encourages investors to review other factors that may affect its future results in the Company’s annual report and other filings with the U.S. Securities and Exchange Commission. As a result, you are cautioned not to rely on any forward-looking statements.
