Forward-Looking Statements Statements contained in this presentation regarding matters that are not historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. Words such as “will,” "anticipates," "believes," "expects," "intends," “plans,” “potential,” "projects,” “would” and "future" or similar expressions are intended to identify forward-looking statements. These forward-looking statements include, but are not limited to, statements regarding: the therapeutic potential of Finch’s product candidates to have the potential to be a transformative new class of medicines, including the potential of CP101 to fulfill the need for a convenient, one-time oral therapy for the prevention of recurrent CDI; the anticipated timing for topline data for PRISM4; the ability for CP101 to function as a Complete Consortia product candidate that delivers a diverse, donor-derived microbial community to restore broad community function; the safety profile of CP101 and its potential to serve a large population in recurrent CDI; potential label expansion opportunities for CP101; the Company's ability to execute upon its mission and strategic priorities; potential strategic partnerships to advance Finch’s product candidates; opportunities to leverage clinical data generated by third party studies to inform Finch’s ASD program strategy; possible alternative clinical development strategies for CP101 and Finch’s other product candidates; its expectations regarding the potential market size and the rate and degree of market acceptance for any product candidates that it develops; the therapeutic value and commercial potential of candidates developed using its Human-First Discovery platform; the strength of the Company's patent portfolio; and the Company’s anticipated runway. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. These risks and uncertainties include, among others, those related to: the Company’s limited operating history and historical losses; the Company’s ability to raise additional funding to complete the development and any commercialization of its product candidates and the potential impact of termination of the Company’s collaboration with Takeda on such funding requirements and the Company’s ability to obtain funding; the Company’s dependence on the success of its lead product candidate, CP101; the possibility that the Company may be delayed in initiating, enrolling or completing any clinical trials, including PRISM4; unexpected regulatory actions or delays, such as requests for additional safety and/or efficacy data or analysis of data, and including with respect to the FDA's planned review of the validation package for one of the Company’s release tests, which is utilized for CP101; results of clinical trials may not be sufficient to satisfy regulatory authorities to approve the Company’s product candidates in their targeted or other indications (or such authorities may request additional trials or additional information); results of clinical trials may not be indicative of final or future results from later stage or larger clinical trials (or in broader patient populations once the product is approved for use by regulatory agencies) or may not be favorable or may not support further development; the Company’s product candidates, including CP101, may not generate the benefits to patients that are anticipated; the Company’s ability to comply with regulatory requirements and continued regulatory review, which may result in significant additional expense and with respect to which the Company may be subject to penalties for failure to comply; competition from third parties that are developing products for similar uses; the Company’s ability to maintain patent and other intellectual property protection and the possibility that the Company’s intellectual property rights may be infringed, invalid or unenforceable or will be threatened by third parties; the Company’s ability to qualify and scale its manufacturing capabilities; the Company’s lack of experience in selling, marketing and distributing its product candidates; the Company’s dependence on third parties in connection with manufacturing, clinical trials and preclinical studies; and risks relating to the impact and duration of the COVID-19 pandemic on the Company’s business. These and other risks are described more fully in the Company’s filings with the Securities and Exchange Commission (“SEC”), including the section titled “Risk Factors” in the Company’s Annual Report on Form 10-K filed with the SEC on March 31, 2022, as supplemented by the Company's Quarterly Reports on Form 10-Q filed with the SEC on May 16, 2022 and August 11, 2022, as well as discussions of potential risks, uncertainties, and other important factors in the Company’s other filings with the SEC. All forward-looking statements contained in this presentation speak only as of the date on which they were made. Except to the extent required by law, 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. Certain information contained in this presentation relates to or is based on studies, publications, surveys and other data obtained from third-party sources and the Company’s own internal estimates and research.
