Forward-looking statements reflect our current views with respect to, among other things, our operations and financial performance. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q are forward-looking statements. You can generally identify these forward-looking statements by terminology such as “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “seek,” “approximately,” “predict,” “intend,” “plans,” “estimates,” “anticipates” or the negative version of these terms or other comparable terminology. Forward-looking statements inherently involve many risks and uncertainties that could cause actual results to differ from those expressed in forward-looking statements. Forward-looking statements are based on management’s current plans and expectations, expressed in good faith and believed to have a reasonable basis. However, we can give no assurance that any expectation or belief will result or will be achieved or accomplished. Investors therefore should not place undue reliance on forward-looking statements.

These forward-looking statements include, but are not limited to, statements about:

More information on factors that could cause our actual results to differ from those expressed in forward-looking statements is included from time to time in our reports filed with the Securities and Exchange Commission, including in our Annual Report on Form 10-K for the year ended December 31, 2025, particularly under Part I, Item 1A, “Risk Factors.” Investors should understand that it is not possible to predict or identify all such factors and should not consider the risks described above and under Part I, Item 1A, “Risk Factors” of our Annual Report on Form 10-K to be a complete statement of all potential risks and uncertainties. All forward-looking statements in this Quarterly Report on Form 10-Q speak only as of the date of this Quarterly Report on Form 10-Q and are expressly qualified in their entirety by the cautionary statements included in or incorporated by reference into this Quarterly Report on Form 10-Q. Except as required by law, we expressly disclaim any obligation to publicly release any revisions to forward-looking statements to reflect events after the date of this Quarterly Report on Form 10-Q.

This Quarterly Report on Form 10-Q also contains estimates, projections and other information concerning our industry, our business, and the markets for certain medical conditions, including data regarding the estimated size of those markets, and the incidence and prevalence of certain medical conditions. Information that is based on estimates, forecasts, projections, market research or similar methodologies is inherently subject to uncertainties and actual events or circumstances may differ materially from events and circumstances reflected in this information. Unless otherwise expressly stated, we obtained this industry, business, market and other data from reports, research surveys, studies and similar data prepared by market research firms and other third parties, industry, medical and general publications, government data and similar sources.
