Forward-looking statements include all statements that do not relate solely to historical or current facts and can be identified by the use of words such as "believes", "expects", "anticipates", "may", "will", "should", "seeks", "approximately", "intends", "projects", "plans", "estimates" or the negative of these words or other comparable terminology (as well as other words or expressions referencing future events, conditions or circumstances). Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. These forward-looking statements include, but are not limited to, statements regarding the market size and potential growth opportunities of our current product candidates; the safety, efficacy, tolerability and other potential benefits, such as weight loss, associated with our current product candidates; the competitive differentiators of our current product candidates; our planned clinical trial activities for our current product candidates; and the expected timeline for topline data release dates. Many factors could cause actual future events to differ materially from the forward-looking statements in this presentation, including, without limitation, those risks associated our history of net losses, the sufficiency of our existing cash on hand to fund operations and raising additional capital; adverse global economic conditions; our ability to execute on our commercial strategy; the timeline for regulatory submissions; the ability to obtain regulatory approval through the development steps of our current and future product candidates; the ability to realize the benefits of the license agreement with Dong-A ST Co. Ltd. (the "License Agreement"), including the impact on our future financial and operating results; the cooperation of our contract manufacturers, clinical study partners and others involved in the development of our current and future product candidates; potential negative interactions between our product candidates and any other products with which they are combined for treatment; our ability to initiate and complete clinical trials on a timely basis; our ability to recruit subjects for its clinical trials; whether we receive results from our clinical trials that are consistent with the results of pre-clinical and previous clinical trials; impact of costs related to the License Agreement, known and unknown, including costs of any litigation or regulatory actions relating to the License Agreement; the effects of changes in applicable laws, regulations or Nasdaq listing rules; and the effects of changes to our stock price. These forward-looking statements are based on information currently available to us and our current plans or expectations and are subject to a number of known and unknown uncertainties, risks and other important factors that may cause our actual results, performance or achievements expressed or implied by the forward-looking statements. These and other important factors are described in detail in the "Risk Factors" section of our Annual Report on Form 10-K for the year ended December 31, 2025, and our other filings with the Securities and Exchange Commission. While we may elect to update such forward-looking statements at some point in the future, except as required by law, we disclaim any obligation to do so, even if subsequent events cause our views to change. Although we believe the expectations reflected in such forward-looking statements are reasonable, we can give no assurance that such expectations will prove to be correct. These forward-looking statements should not be relied upon as representing our views as of any date subsequent to this presentation. This presentation also may contain estimates and other statistical data made by independent parties and by us relating to market size and other data about our industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions and estimates of our future performance and the future performance of the markets in which we operate are necessarily subject to a high degree of uncertainty and risk. |
