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, the clinical data from Structure’s Phase 1b MAD study for GSBR-1290, the clinical update from Structure’s Phase 2a study, for GSBR-1290 in patients with type 2 diabetes and obesity, any expectations regarding the safety, efficacy or tolerability of GSBR-1290 and other candidates under development, the ability of GSBR-1290 to treat type 2 diabetes, obesity or related indications, , the planned initiation and study design of Structure’s Phase 2b studies for GSBR-1290 in patients with type 2 diabetes and obesity and the timing thereof; the planned timing of the Company’s data results and continued development of GSBR-1290 and next generation combination GLP-1R candidates and expectations regarding an oral development candidate targeting GLP-1R. 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, 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 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, the timing and results of preclinical and clinical trials, the Company’s ability to fund development activities and achieve development goals, the impact of any global pandemics, inflation, supply chain issues, rising interest rates and future bank failures 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 filed with the SEC on March 30, 2023, Quarterly Report on Form 10-Q filed with the SEC on August 10, 2023, 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.
