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 condensed consolidated balance sheet as of June 30, 2025 as the Company had not yet received the related goods or services. As of June 30, 2025, the Company had open purchase commitments for goods and services of $1.5 million, of which $1.1 million are expected to be received through the next 12 months.

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.

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.

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.
