Our properties consist of leased office, laboratory, warehouse and assembly facilities. Our administrative offices and research facilities are located in San Diego, California. We also lease a building in Minnetonka, Minnesota consisting of office, assembly operations, and warehousing space, two leased buildings in Boston, Massachusetts consisting of office and lab space and have a small leased administrative office in Ewing, New Jersey. We lease an aggregate of approximately 196,000 square feet of space. We pay a pro rata share of operating costs, insurance costs, utilities and real property taxes. Additionally, we lease certain office equipment and vehicles under operating leases. Total rent expense was approximately $9.4 million, $8.6 million and $9.3 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Legal Contingencies
From time to time, we may be involved in disputes, including litigation, relating to claims arising out of operations in the normal course of our business. Any of these claims could subject us to costly legal expenses and, while we generally believe that we have adequate insurance to cover many different types of liabilities, our insurance carriers may deny coverage or our policy limits may be inadequate to fully satisfy any damage awards or settlements. If this were to happen, the payment of any such awards could have a material adverse effect on our consolidated statements of income and balance sheets. Additionally, any such claims, whether or not successful, could damage our reputation and business. We currently are not a party to any legal proceedings, the adverse outcome of which, in our opinion, individually or in the aggregate, would have a material adverse effect on our consolidated statements of income or balance sheets.

About Commitments Disclosures

Commitments and contingencies disclosures catalog a company's off-balance-sheet obligations and legal exposures — purchase commitments, guarantee arrangements, pending litigation, and regulatory proceedings. These items represent potential future cash outflows that may not appear as liabilities on the balance sheet until they become probable and estimable.

Key signals: litigation reserves and disclosed loss ranges quantify management's estimate of legal exposure, but unquantified "reasonably possible" losses often represent the larger risk. Watch for changes in language around pending cases — shifts from "remote" to "reasonably possible" or increases in estimated loss ranges signal deteriorating outcomes. Unconditional purchase obligations and take-or-pay contracts create fixed cost structures that reduce operational flexibility. Guarantee arrangements for subsidiaries or joint ventures can create cascading obligations. Compare the total commitment schedule against projected free cash flow to assess whether the company can meet its obligations without additional financing.
