2 Disclaimers and Forward Looking Statements This presentation contains “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including, without limitation, statements concerning the Company’s future plans and prospects, any expectations regarding the safety, efficacy, tolerability and chemistry, manufacturing and controls and scalability of GSBR-1290 under development based on the topline clinical data from the Phase 2a study of GSBR-1290 in patients with type 2 diabetes mellitus (T2DM) and obesity, including the potential for maintained or increased efficacy results with longer duration of treatment, the ability of GSBR-1290 to treat T2DM, obesity, chronic weight management or related indications, the planned initiation and study design of the Company's Phase 2b study for GSBR-1290 in patients with obesity and the timing thereof; the update from the capsule to tablet formulation bridging optimization study of GSBR-1290; the planned timing to submit an investigational new drug application to support a Phase 2b study for chronic weight management for GSBR-1290; the planned timing of the Company's data results and continued development of GSBR-1290 and next generation combination GLP-1R candidates; the Company’s anticipated milestones; the anticipated market opportunity for GSBR-1290 and oral small molecules and the Company’s expected cash runway until 2026. In addition, when or if used in this presentation, the words “may,” “could,” “should,” “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “predict” and similar expressions and their variants, as they relate to the Company may identify forward-looking statements. Forward-looking statements are neither historical facts nor assurances of future performance. Although the Company believes the expectations reflected in such forward-looking statements are reasonable, the Company can give no assurance that such expectations will prove to be correct. Readers are cautioned that actual results, levels of activity, safety, efficacy, performance or events and circumstances could differ materially from those expressed or implied in the Company’s forward-looking statements due to a variety of risks and uncertainties, which include, without limitation, risks and uncertainties related to topline results that the Company reports is based on a preliminary analysis of key efficacy and safety data, and such data may change following a more comprehensive review of the data related to the clinical trial and such topline data may not accurately reflect the complete results of a clinical trial, the preliminary nature of the results due to length of the study and sample size and results from earlier clinical trials not necessarily being predictive of future results, including the results using the least square means and mixed model for repeated measures which uses all available data, including data from patients who did not follow-up at 12 weeks, and estimates how patients with missing data would have responded based on patients who continued the study and had similar baseline characteristics (implicit imputation), potential delays in the IND submission or commencement, enrollment and completion of the Company's planned Phase 2 trials, including the Company will need to receive allowance from the FDA to proceed before initiating the planned Phase 2b trial, the Company's ability to advance GSBR-1290, LTSE-2578, ANPA-0073 and its other therapeutic candidates, obtain regulatory approval of and ultimately commercialize the Company's therapeutic candidates, competitive products or approaches limiting the commercial value of the Company's product candidates,the timing and results of preclinical and clinical trials, the impact of any data collection omissions at any of our clinical trial sites, the Company’s ability to fund development activities and achieve development goals, the Company's reliance on third parties, including clinical research organizations , manufacturers, suppliers and collaborators, over which it may not always have full control, the impact of any global pandemics, inflation and supply chain issues on the Company’s business, its ability to protect its intellectual property and other risks and uncertainties described in the Company’s filings with the Securities and Exchange Commission (SEC), including the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on March 8, 2024, Quarterly Report on Form 10-Q for the quarter ended March 31, 2024 filed with the SEC on May 9, 2024, and future reports the Company may file with the SEC from time to time. All forward-looking statements contained in this presentation speak only as of the date on which they were made and are based on management’s assumptions and estimates as of such date. The Company undertakes no obligation to update such statements to reflect events that occur or circumstances that exist after the date on which they were made, except as required by law.

These selective targets are aspirational, and are based on assumptions and estimates by the Company that may prove to be wrong. In addition, the results of prior clinical trials and preclinical studies are not necessarily predictive of future results, and any extrapolations based on past results are inherently uncertain and imprecise. Therefore, investors are cautioned to not rely on these aspirational targets.
