Commitments and Contingencies
Purchase Commitments
Open purchase commitments are for the purchase of goods and services related to, but not limited to, research and development, facilities, and professional services under non-cancellable contracts. They were not recorded as liabilities on the consolidated balance sheet as of December 31, 2025 as the Company had not yet received the related goods or services. As of December 31, 2025, the Company had open purchase commitments for goods and services of $1.5 million, of which $1.4 million are expected to be received through the next 12 months.
Legal Proceedings
From time to time, the Company may become involved in litigation relating to claims arising from the ordinary course of business. The Company may record accruals for loss contingencies associated with legal matters when it is probable that a liability will be incurred, and the amount of the loss can be reasonably estimated. Amounts accrued for legal contingencies often result from a complex series of judgments about future events and uncertainties that rely heavily on estimates and assumptions. The ability to make such estimates and judgments can be affected by various factors including, among other things, whether damages sought in the proceedings are unsubstantiated or indeterminate; scientific and legal discovery has not commenced or is not complete; proceedings are in early stages; matters present legal uncertainties; there are significant facts in dispute; procedural or jurisdictional issues. Loss contingency accruals would be included in accrued and other liabilities and general and administrative expenses.
U.S. District Court Proceedings
On December 14, 2023, we filed suit in the United States District Court for the Northern District of California (the “Court”) against Somalogic, Inc. (Somalogic) which recently merged with and is now part of “Standard Biotools, Inc.,” and the California Institute of Technology. This suit sought declaratory judgment that Nautilus does not infringe any claims of US Patent No. 7,842,793 related to DNA origami structures (the ‘793 Patent), which Somalogic had allegedly licensed from the California Institute of Technology through its purchase of Palamedrix, Inc. On November 19, 2024, the Company, Standard Biotools, Inc., and the California Institute of Technology agreed to dismiss the suit and settle any and all disputes and/or claims related to the suit.
Leases
The Company is obligated under certain non-cancellable operating leases for office space and laboratory space. This space includes operating leases in Seattle, Washington, San Carlos, California, and San Diego, California.
Seattle Lease
In July 2021, the Company entered into a 7-year non-cancellable operating lease, which commenced in August 2021, for office space in Seattle, Washington. Total non-cancellable payments under this lease aggregate $4.5 million through June 2028.
San Carlos Leases
In December 2020, the Company entered into a new lease in San Carlos, California for ten years which commenced in October 2021 and expiring in October 2031 with total minimum lease payments of $40.7 million.
In December 2021, the Company entered into another lease in San Carlos, California for nine years commencing in March 2023. The lease provided the Company the option to terminate the agreement without significant penalty after five years from the commencement date. At lease commencement, the Company concluded it was reasonably certain to exercise the early termination option and determined that the lease term was five years with total minimum lease payments of $7.2 million. The Company utilized $2.0 million from the landlord with an interest rate of 7% to finance its tenant improvements. The principal and interest payments are included in the payments used to measure the lease liability.
In December 2025, the Company revised expectations regarding future space requirements and concluded it was no longer reasonably certain the Company will exercise the early termination option. Based on this determination, the Company remeasured the lease to reflect an updated remaining lease term through October 2031, resulting in an increase to the lease liability and corresponding operating lease right-of-use (“ROU”) asset of approximately $4.2 million as of the remeasurement date. The revised measurement reflects the present value of the remaining fixed lease payments discounted using the Company’s updated incremental borrowing rate. No other significant assumptions were modified as part of the remeasurement.
San Diego Lease
In November 2022, the Company entered into a lease in San Diego, California for 39 months commencing in December 2022. Total non-cancellable payments under this lease aggregate $2.1 million through March 2026.
The components of lease costs which were included in operating expenses in the consolidated statements of operations were as follows:

Fixed operating lease costs$7,224 $7,233 
Variable operating lease costs3,411 2,904 
Total lease costs$10,635 $10,137 
For the years ended December 31, 2025 and 2024, cash paid for amounts included in the measurement of operating lease liabilities included in cash flows used in operating activities was $7.2 million and $7.0 million, respectively.
As of December 31, 2025, the weighted-average remaining lease term and weighted-average discount rate for operating leases was 5.6 years and 9.0%, respectively.
The following table summarizes the Company's future principal contractual obligations for operating lease commitments as of December 31, 2025:

The Company has $1.0 million in cash-collateralized letters of credit with one financial institution in lieu of security deposits in connection with the San Carlos and San Diego lease agreement.
Indemnification Agreements
In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the Company may indemnify, hold harmless and defend an indemnified party for losses suffered or incurred by the indemnified party. Some of the provisions will limit losses to those arising from third-party actions. In some cases, the indemnifications will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. The Company has never incurred material costs to defend lawsuits or settle claims related to these indemnification provisions.
The Company has also agreed to indemnify its directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by them in any action or proceeding to which any of them are, or are threatened to be, made a party by reason of their service as a director or officer. The Company maintains director and officer insurance coverage that would generally enable it to recover a portion of any future amounts paid. The Company may be subject to indemnification obligation by law with respect to the actions of its employees under certain circumstances and in certain jurisdictions.

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.
