5. Leases

We lease 35,183 square feet of office space in Minneapolis, Minnesota, which houses our principal executive offices and our manufacturing facility. We lease this space under an operating lease agreement that commenced December 1, 2008, and was scheduled to expire August 31, 2024. On April 21, 2023, we extended the operating lease for our office space in Minneapolis, Minnesota for an additional 49 consecutive months through August 31, 2028. On November 7, 2023, we expanded our existing office space with the addition of 7,615 square feet of property adjacent to our principal executive offices and our manufacturing facility. On May 20, 2025, we further increased our office space by leasing an additional 3,678 square feet of the contiguous property. The term on this expanded property is for 40 consecutive months that will run concurrently with the term on the existing lease. We intend to add new facilities as we grow, and we believe that suitable additional or substitute space will be available as needed to accommodate any such expansion of our operations. Our operating lease agreement includes an option to renew for one additional period of

three years. The exercise of the lease renewal option is at our sole discretion and was not included in the lease term for the calculation of the ROU asset and lease liability, as it is not reasonably certain of exercise.

In addition to base rent, we also pay our proportionate share of operating expenses, as defined in the lease. These payments are made monthly and are adjusted annually to reflect actual charges incurred for operating expenses, such as common area maintenance, taxes, and insurance.
