• Initiates $150M At-The-Market (ATM) Offering

  REGENXBIO Inc. has filed a prospectus supplement to offer and sell up to $150 million of its common stock through an At-The-Market (ATM) offering facility with Leerink Partners LLC. This offering finalizes the terms of a capital raise initiated with a prospectus dated December 12, 2025.

• Significant Dilution Expected

  The offering, which could represent approximately 35.5% of the company's current market capitalization, is highly dilutive. The filing illustrates an immediate dilution of approximately $4.01 per share for new investors, based on an assumed offering price of $8.50 per share.

• Discloses Substantial Doubt About Going Concern

  The company explicitly states that conditions raise "substantial doubt about our ability to continue as a going concern within 12 months from the date of this prospectus supplement." Furthermore, it does not anticipate that the net proceeds from this offering will alleviate this doubt.

• Follows Major Regulatory Setbacks

  This capital raise comes shortly after significant negative regulatory news, including FDA clinical holds on its RGX-111 and RGX-121 gene therapy programs (announced January 28, 2026) and a Complete Response Letter (CRL) for its RGX-121 Biologics License Application (BLA) (announced February 10, 2026).

This 424B5 filing formalizes an At-The-Market (ATM) offering to raise up to $150 million, representing a substantial portion of the company's market capitalization. The timing of this highly dilutive capital raise is critical, following closely on the heels of significant negative regulatory news, including FDA clinical holds on two gene therapy programs (RGX-111 and RGX-121) and a Complete Response Letter for the RGX-121 BLA. The company explicitly states "substantial doubt about our ability to continue as a going concern" and notes that the proceeds from this offering are not expected to alleviate this doubt. This indicates a dire financial situation, where the company is seeking necessary capital to extend its operational runway despite severe setbacks and without a clear path to long-term financial stability. Investors should be aware of the significant dilution and the company's precarious financial and regulatory position.
