Hyliion Holdings Corp.

Our headquarters are located in an approximately 152,000 square foot facility comprised of two buildings that we lease in Cedar Park, Texas, just north of Austin, Texas, where our administrative function is primarily located. Our lease of this facility expires in April 2027, and we have the option to extend the lease for two additional five-year terms. In February 2025 we subleased approximately 27,000 square feet of this facility. We also lease an approximately 30,000 square foot facility in Milford, Ohio near, Cincinnati, Ohio, where we design and develop the KARNO technology. Our lease of the Ohio facility expires in June 2028, with the option to extend the term for up to two consecutive terms of three years. We believe that our current facilities are in good working order and are capable of supporting our operations for the foreseeable future; however, we will continue to evaluate buying or leasing additional space as needed to accommodate our growth.
