Neurogene Inc.

We currently lease two properties for our principal offices: an approximately 42,000 square foot manufacturing facility in Houston, Texas, and an approximately 6,000 square foot office space in New York, New York. The Houston manufacturing facility is used for our in-house manufacturing, warehouse and cold storage functions, and the lease expires on August 31, 2029. The New York office space is our corporate headquarters, and the lease expires on June 30, 2026. In addition, we have established a hybrid work-from-home policy for many of our employees. We believe these spaces to be sufficient to meet our needs for the foreseeable future and that any additional space we may require will be available on commercially reasonable terms.

In addition to our principal offices, we also lease a combined 39,572 square feet of office and laboratory space in Seattle, Washington that was previously used by Neoleukin prior to the merger for laboratory, discovery, research and development and general and administrative purposes. We have entered into a sublease with an unrelated third party for 6,272 square feet of that space, which will terminate concurrently with the end of our lease for such space on September 30, 2026. We are actively looking for a subtenant for the remaining 33,300 square feet of combined laboratory and office space, which is subject to a lease that will terminate on June 30, 2029. Any net proceeds we receive from any sublease of these properties will be payable to the holders of CVRs issued in connection with the merger, after adjustment for certain costs.
