Pyxis Oncology, Inc.

Our headquarters are located at 321 Harrison Avenue, Boston, MA 02118, where we lease approximately 31,659 rentable square feet of office and laboratory space under a lease that terminates on December 31, 2032, with an additional five-year option to extend the lease beyond December 31, 2032. We also entered into a sublease for 17,729 square feet of this office and laboratory space commencing on March 24, 2023. The sublease agreement will continue through March 31, 2026, with an option for the sublessee to extend the sublease for a one-year period. We continue to be responsible for performance under this lease until it expires on December 31, 2032.

We believe that our existing facilities are adequate to meet our current needs, and that suitable additional alternative spaces will be available in the future on commercially reasonable terms.
