NEW YORK / Nov 04, 2024 / Business Wire / Neurogene Inc. (Nasdaq: NGNE), a clinical-stage company founded to bring life-changing genetic medicines to patients and families affected by rare neurological diseases, today announced that it has entered into a securities purchase agreement for a private investment in public equity (“PIPE”) financing that is expected to result in gross proceeds of approximately $200 million to Neurogene, before placement agent fees and offering expenses. The oversubscribed PIPE financing included participation from a U.S.-based healthcare focused investor, RTW Investments, Casdin Capital, EcoR1 Capital, Redmile Group, Great Point Partners, LLC, Commodore Capital and Samsara BioCapital.

Pursuant to the terms of the securities purchase agreement, Neurogene is selling an aggregate of (i) 1,835,000 shares of its common stock (“Common Stock”) at a purchase price of $50.00 per share and (ii) pre-funded warrants to purchase 2,165,042 shares of Common Stock at a price of $49.999 per pre-funded warrant. The pre-funded warrants have an exercise price of $0.001 per share. Following the transaction, there will be approximately 21.0 million shares of common stock outstanding (assuming the exercise in full of all pre-funded warrants). The PIPE financing is expected to close on or about November 5, 2024, subject to satisfaction of customary closing conditions.

Neurogene expects the net proceeds from the PIPE financing along with its existing cash and cash equivalents will provide runway into the second half of 2027. Neurogene anticipates the funding will allow for the completion of enrollment of a future registrational study for NGN-401 for Rett syndrome, CMC scale-up to support NGN-401 registrational activities, further development of its EXACT™ gene therapy pipeline and other general corporate purposes.

Neurogene will host a webcast to review the safety data from the low- and high-dose cohorts and interim efficacy data from the low-dose cohort of the NGN-401 Phase 1/2 trial on November 11, 2024 at 4:30 p.m. ET.

TD Cowen, Leerink Partners, Stifel and William Blair are acting as joint placement agents for the private placement.
