Legal Disclaimers This presentation contains certain forward-looking statements within the meaning of the federal securities laws. Forward-looking statements generally are accompanied by words such as “will,” “plan,” “intend,” “potential,” “expect,” “could,” or the negative of these words and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding Surrozen’s discovery, research and development activities, in particular its development plans for its product candidates (including anticipated clinical development plans and timelines, the availability of data, the potential for such product candidates to be used to treat human disease, as well as the potential benefits of such product candidates) and the Company’s partnership with Boehringer Ingelheim, including the potential for future success-based development, regulatory, and commercial milestone payments, in addition to mid-single digit to low-double digit royalties on sales. These statements are based on various assumptions, whether or not identified in this presentation, and on the current expectations of the management of Surrozen and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on as a guarantee, an assurance, a prediction, or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of Surrozen. These forward-looking statements are subject to a number of risks and uncertainties, including the initiation, cost, timing, progress and results of research and development activities, preclinical and clinical trials with respect to its product candidates, and potential future drug candidates; Surrozen’s ability to fund its preclinical and clinical trials and development efforts, whether with existing funds or through additional fundraising; Surrozen’s ability to identify, develop and commercialize drug candidates; Surrozen’s ability to successfully complete preclinical and clinical studies for its product candidates; the effects that arise from volatility in global economic, political, regulatory and market conditions; and all other factors discussed in Surrozen’s Annual Report on Form 10-K for the year ended December 31, 2023 and Surrozen’s Quarterly Report on Form 10- Q for the quarter ended September 30, 2024 to be filed with the Securities and Exchange Commission ( SEC ) under the heading “Risk Factors,” and other documents Surrozen has filed, or will file, with the Securities and Exchange Commission. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that Surrozen presently does not know, or that Surrozen currently believes are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Surrozen’s expectations, plans, or forecasts of future events and views as of the date of this presentation. Surrozen anticipates that subsequent events and developments will cause its assessments to change. However, while Surrozen may elect to update these forward-looking statements at some point in the future, Surrozen specifically disclaims any obligation to do so, except as required by law. These forward-looking statements should not be relied upon as representing Surrozen’s assessments of any date after the date of this presentation. Accordingly, undue reliance should not be placed upon the forward-looking statements. 2 © 2025 Surrozen, Inc.
