Forward Looking Statement This presentation (the "Presentation") contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 about Vor Biopharma Inc. ("Vor," "Vor Bio" or the "Company"). The words "aim," "anticipate," "believe," "can," "could," "design," "enable" "estimate," "expect," "intend," "may," "ongoing," "plan," "potential," "project," "should," "target," "towards," "will," and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements in this Presentation include those regarding Vor Bio's plans for development and commercialization of telitacicept, including expected milestones such as trial initiation and data readout; the potential of telitacicept in various indications including generalized myasthenia gravis (gMG) and primary Sjögren's disease; the Company's ambition to transform the approach to B cell-driven autoimmune disease; the potential of telitacicept to be a best- and first-in-class BAFF/APRIL inhibitor; the expected safety profile of telitacicept; the market opportunities for telitacicept; the addressable patient populations in the indications Vor Bio intends to treat; Vor Bio's cash runway; and other statements that are not historical fact. Vor Bio may not actually achieve the plans, intentions, or expectations disclosed in these forward-looking statements, and you should not place undue reliance on these forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in these forward-looking statements as a result of various factors, including: uncertainties inherent in the initiation, completion of, and availability and timing of results from, clinical trials; whether preclinical data or interim results from a clinical trial will be predictive of the final results of the trial or the results of future trials; the uncertainty of regulatory approvals to conduct trials or to market products; Vor Bio's reliance on third parties over which it may not always have full control; and the availability of funding sufficient for Vor Bio's foreseeable and unforeseeable operating expenses and capital expenditure requirements. These and other risks are described in greater detail under the caption "Risk Factors" included in Vor Bio's most recent annual or quarterly report and in other reports it has filed or may file with the Securities and Exchange Commission. Any forward-looking statements contained in this Presentation speak only as of the date of this Presentation, and Vor Bio expressly disclaims any obligation to update any forward-looking statements, whether because of new information, future events or otherwise, except as may be required by law. Certain information contained in this Presentation relates to or is based on studies, publications, surveys and other data obtained from third party sources and Vor Bio's own internal estimates and research. While the Company believes these third-party sources to be reliable as of the date of this Presentation, the Company has not independently verified, and makes no representation as to the adequacy, fairness, accuracy or completeness of, any information obtained from third party sources. In addition, there can be no guarantee as to the accuracy or reliability of any assumptions or limitations that may be included in such third-party information. While the Company believes its own internal research is reliable, such research has not been verified by any independent source.
