Facility Leases

In December 2016, the Company entered into a lease agreement for office and laboratory space in South San Francisco, California. The lease was initially set to expire in May 2025 with two five-year renewal options. In June 2024, the Company amended the lease to extend the term to November 2027. Pursuant to the terms of the amended lease, the Company has one remaining five-year renewal option.

In February 2021, the Company entered into a lease agreement for office and manufacturing space in Union City, California. The lease commenced in May 2021 and has a ten-year term with one five-year renewal option. On June 29, 2026, the Company entered into a lease termination agreement with the landlord. Pursuant to the agreement, the lease will terminate on August 31, 2026, instead of its original expiration in July 2031. The Company is not required to remove tenant improvements or restore the premises and may surrender the facility in its existing condition. As consideration for the lease termination, the Company agreed to forfeit its $1.8 million security deposit and pay a one-time lease termination fee of $0.3 million. The Company accounted for the termination agreement as a lease modification under ASC 842 and remeasured the related operating lease liability and right-of-use asset as of June 30, 2026. As a result of the lease modification, the Company recognized a net loss on lease termination of $1.4 million during the three and six months ended June 30, 2026, consisting of the security deposit forfeiture and a brokerage commission incurred in connection with the lease termination, partially offset by the gains recognized upon remeasurement of the operating lease liability and right-of-use asset and the derecognition of the asset retirement obligation liability.

As of June 30, 2026, the Company’s operating leases had a weighted average remaining lease term of 1.3 years and a weighted average discount rate of 8.1%. As of December 31, 2025, the Company’s operating leases had a weighted average remaining lease term of 4.1 years and a weighted average discount rate of 9.1%. Future minimum lease payments under the Company’s operating leases as of June 30, 2026 were as follows:

Purchase Commitments

The Company enters into contractual agreements with various suppliers in the normal course of its business, including vendors that provide machinery and equipment. All contracts are terminable, with varying provisions regarding termination. In general, if a contract with a specific vendor were to be terminated, the Company would only be obligated for the products or services that the Company had received up to the time of termination.

Contingencies

From time to time, the Company may become involved in litigation and other legal actions. The Company estimates the range of liability related to any pending litigation where the amount and range of loss can be estimated. The Company records its best estimate of a loss when the loss is considered probable. Where a liability is probable and there is a range of estimated loss with no best estimate in the range, the Company records a charge equal to at least the minimum estimated liability for a loss contingency when both of the following conditions are met: (i) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements and (ii) the range of loss can be reasonably estimated. The Company was not involved in any material litigation as of June 30, 2026.

Indemnification

In the normal 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. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amounts of future payments the Company could be required to make under these provisions is not determinable. In addition, the Company has entered into indemnification agreements with its directors and certain officers that may require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or

officers. As of June 30, 2026, the Company did not have any material indemnification claims that were probable or reasonably possible and, consequently, has not recorded any related liabilities.
