BOSTON, March 27, 2026 (GLOBE NEWSWIRE) -- Vor Bio (NASDAQ:VOR), a clinical-stage biotechnology company transforming the treatment of autoimmune diseases, announced today that it has entered into a securities purchase agreement to sell 5,338,078 shares of its common stock at a price of $14.05 per share in a private placement. Vor Bio anticipates the gross proceeds from the private placement to be approximately $75 million, before deducting any offering-related expenses. Vor Bio did not engage a placement agent in connection with the private placement. The private placement is expected to close on or about March 30, 2026, subject to the satisfaction of customary closing conditions.

The financing is led by new investor TCGX.

"BAFF/APRIL inhibition represents one of the next major waves of innovation in autoimmune disease, and telitacicept is at the forefront of the field. With compelling Phase 3 data across multiple indications and tens of thousands of patients treated in China, we believe telitacicept's clinical profile and robust safety data to date provide a unique opportunity to bring a differentiated, potentially disease-modifying therapy to patients globally," said Jean-Paul Kress, M.D., Chief Executive Officer and Chairman of Vor Bio. "This financing enables us to accelerate our efforts in generalized myasthenia gravis and, importantly, advance primary Sjögren's disease as a key next frontier – two large, multi-billion-dollar opportunities where significant unmet need remains and where we believe telitacicept can meaningfully change the treatment paradigm. We are well positioned to deliver on our commitment to maximize the impact of telitacicept for patients and drive long-term value for shareholders."

"Our investment reflects the conviction we have in the Vor Bio team and the disruptive potential of telitacicept," said Cariad Chester, Managing Partner at TCGX. "With its differentiated efficacy profile, we believe telitacicept has the potential to become a foundational therapy for multiple B-cell mediated diseases. We are excited to support the pivotal development program of telitacicept and help build Vor Bio into a global leader in treating autoimmune diseases."

Vor Bio intends to use the net proceeds from the private placement to advance the clinical development of telitacicept, including the ongoing global Phase 3 clinical trials for myasthenia gravis and primary Sjögren's disease, business development, and for working capital and general corporate purposes.
