EXPLANATORY NOTE

On July 23, 2026, a securities class action complaint (the “Action”) was filed in the Supreme Court of the State of New York, County of New York, naming as defendants more than 30 publicly traded companies in the U.S., including Wellchange Holdings Company Limited (the “Company”), more than 10 broker-dealer firms in the U.S. and certain other named individuals. The summons and complaint were served on the process agent of the Company on August 11, 2026. The Company is currently reviewing the merits of such Action. The Action is at an early stage and the Company is unable to predict such contingency or estimate any likely outcome at this time.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Statements in this current report with respect to the Company’s current plans, estimates, strategies, beliefs, and other statements that are not historical facts are forward-looking statements about the future performance of the Company. Forward-looking statements include, but are not limited to, those statements using words such as “believe,” “expect,” “plans,” “strategy,” “prospects,” “forecast,” “estimate,” “project,” “anticipate,” “aim,” “intend,” “seek,” “may,” “might,” “could,” or “should,” and words of similar meaning in connection with a discussion of future operations, financial performance, events, or conditions. From time to time, oral or written forward-looking statements may also be included in other materials released to the public. These statements are based on management’s assumptions, judgments, and beliefs in light of the information currently available to it. The Company cautions investors that a number of risks and uncertainties could cause actual results to differ materially from those discussed in the forward-looking statements, including but not limited to, unforeseen legal, regulatory, or operational developments, and other risks contained in reports filed by the Company with the U.S. Securities and Exchange Commission. Therefore, investors should not place undue reliance on such forward-looking statements. Actual results may differ significantly from those set forth in the forward-looking statements. All such forward-looking statements, whether written or oral, and whether made by or on behalf of the Company, are expressly qualified by the cautionary statements and any other cautionary statements which may accompany the forward-looking statements. In addition, the Company disclaims any obligation to update any forward-looking statements to reflect events or circumstances after the date hereof.
