75 Material Cash Requirements and Material Known Contractual Obligations and Commitments Operating Leases Operating lease payments represent our commitment for future minimum rent made under non-cancelable leases for our corporate offices in Palo Alto, California, office and laboratory space in Visp, Switzerland, and related to our Ursus Facility. Total future undiscounted payments for our operating lease obligations as of December 31, 2025 were $73.3 million, of which $15.6 million is due in the next 12 months. Manufacturing Agreements The Company has entered into service and equipment purchase agreements in the normal course of business with various providers of manufacturing services, which can contain minimum commitments or other noncancelable obligations. As of December 31, 2025, future contractual obligations related to these manufacturing agreements that may be subject to cancellation fees were $23.9 million, of which $19.2 million is expected to be due in the next 12 months. In addition, future manufacturing contractual obligations totaling approximately 86.5 million Swiss Francs may be incurred for the potential clinical and commercial supply of tarcocimab and other antibody biopolymer conjugates medicines based on the agreements with Lonza for production at the Ursus Facility. For further information on our leases and manufacturing agreements, refer to Note 8 to our consolidated financial statements included in “Part II, Item 8 — Financial Statements and Supplementary Data” of this Annual Report on Form 10- K. Clinical Agreements The Company may incur potential contingent payments upon our achievement of clinical, regulatory and commercial milestones, as applicable. Due to the uncertainty of the achievement and timing of the events requiring payment under these agreements, the amounts to be paid by us are not fixed or determinable at this time. Critical Accounting Policies, Significant Judgments and Use of Estimates Our consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates. Accrued Research and Development Our accrued research and development costs are estimated based on the level of services performed, including the phase or completion of events, and contracted costs. Accrued clinical trial and related costs are estimated using data such as patient enrollment, clinical site activations or information provided by outside service providers regarding their actual costs incurred. Management determined accrual estimates through reports from and discussions with clinical personnel and outside service providers as to the progress of trials, or the services completed. The estimated costs of research and development provided, but not yet invoiced, are included in accrued liabilities and other current liabilities on the consolidated balance sheet. If the actual timing of the performance of services or the level of effort varies from the original estimates, we will adjust the accrual accordingly. Payments made to third parties under these arrangements in advance of the performance of the related services are recorded as prepaid expenses and other assets until the services are rendered.
