HCW Biologics Inc.

On August 15, 2022, we purchased a 36,000 square foot building located in Miramar, Florida, as our new headquarters. We intend to use the new facility for research and development laboratories and facilities for manufacturing, as well as offices for our employees, including clinical development, research, development, quality control, quality assurance, regulatory affairs, and administration. We have been in the process of refitting the building for our purposes. Our relocation to the new headquarters is anticipated in the mid-2026. We expect our cGMP manufacturing facility to be validated and operational by the end of 2026. We continue to occupy approximately 12,250 square feet of space in Miramar, Florida and currently lease this space under the terms of a lease that commenced on March 1, 2025 and terminates on February 28, 2026. Given our long relationship with the landlord of our leased location, we believe we will be able to negotiate an extension our lease, if required. We believe our existing location is sufficient to meet our current and near-term needs.
