1. Nature of the Business

Vor Biopharma Inc. (the “Company”) is a clinical-stage company advancing telitacicept, a novel, dual-target recombinant fusion protein that inhibits both BLyS (BAFF) and APRIL—two key cytokines involved in B cell survival and autoantibody production. This dual-target mechanism reduces autoreactive B cells and autoantibody production, key drivers of autoimmune pathology. The Company is headquartered in Boston, Massachusetts. The Company was incorporated on December 30, 2015.

Risks and Uncertainties

The Company is subject to a number of risks common to development stage companies in the biotechnology industry, including, but not limited to, risks of failure of clinical trials, dependence on key personnel, protection of proprietary technology, reliance on third party organizations, uncertainty of obtaining regulatory approval for any product candidate that it may develop, development by competitors of technological innovations, compliance with government regulations, adverse macroeconomic conditions and the need to obtain additional financing.

Liquidity and Capital Resources

The Company expects that its existing cash, cash equivalents and marketable securities as of March 31, 2026 of $491.5 million will be sufficient to allow the Company to fund its current planned operations through at least a period of one year after the date the financial statements are issued.

As of March 31, 2026, the Company has an accumulated deficit of $1,372.6 million. The Company anticipates that it will continue to incur significant operating losses for the next several years as it continues to develop its product candidate. As a result, the Company's continued operations are dependent on its ability to raise additional funding. If the Company is unable to obtain additional funding on a timely basis, it may be forced to significantly curtail, delay, or discontinue one or more of its planned research or development programs or be unable to expand its operations.
