Commitments and Contingencies
Milestone Compensation Arrangements
We have performance-based milestone compensation arrangements with certain employees and consultants, whose vesting is contingent upon meeting various milestones, with fixed monetary amounts known at inception that can be settled in the form of cash or equity at our sole discretion. We also have performance-based milestone compensation arrangements with certain employees and consultants as part of the 2020 Stock and Equity Award Exchange Program (the “Exchange Program”, refer to Note 15). The compensation arrangements under the Exchange Program are to be settled in the form of equity only. Performance-based milestone awards that are settled in the form of equity are satisfied in the form of fully-vested RSAs. We accrue for such contingent compensation when the related milestone is probable of achievement and is recorded in “Accrued compensation and benefits” for the current portion and in “Other long-term liabilities” for the noncurrent portion on the consolidated balance sheets. There is no accrued compensation expense for performance-based milestone awards that are assessed to be not probable of achievement. The table below shows our commitment for the potential milestone amounts and the accruals for milestones deemed probable of achievement as of December 31, 2025.

Other Commercial and Research and Development Agreements
We may also enter into contracts in the normal course of business with various counterparties, including vendors for our commercial products, contract research organizations for services related to clinical trials, CMOs for clinical supplies, and other vendors for preclinical studies, supplies, and other operating purposes. These contracts generally provide for termination on notice with potential termination charges. As of December 31, 2025 and 2024, there were no material amounts accrued related to termination charges.
In the normal course of business, we have also entered into contracts which contain minimum noncancellable purchase commitments and obligations. These include commitments for the supply, manufacturing, and packaging of our commercial product as well as agreements to support the sales and marketing activities for Attruby. As of December 31, 2025, we have minimum noncancellable commitments in aggregate of $110.2 million.
Indemnification
In the ordinary course of business, we may provide indemnifications of varying scope and terms to vendors, lessors, business partners, board members, officers, and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by us, our negligence or willful misconduct, violations of law, or intellectual property infringement claims made by third-parties. In addition, we have entered into indemnification agreements with directors and certain officers and employees that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers, or employees. No material demands have been made upon us to provide indemnification under such agreements, and thus, there are no claims that we are aware of that could have a material effect on our consolidated financial statements.
We also maintain director and officer insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and certain officers. To date, we have not paid any claims related to our indemnification obligations, incurred any material costs and have not accrued any material liabilities on the consolidated financial statements as a result of these provisions.
Contingencies
From time to time, we may become involved in legal proceedings arising in the ordinary course of business. We are not currently a party to any material legal proceedings.

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.
