Amprius Technologies, Inc.

We lease our corporate headquarters and manufacturing facilities, which consisted of the following as of December 31, 2024:

•Approximately 51,000 square feet of leased space located in Fremont, California. This leased property, which we use for our corporate headquarters, research and development, and manufacturing of SiMaxx batteries, expires in June 2027 with an option to extend for an additional 5-year period up to June 2032.

•Approximately 774,000 square feet of leased space located in Brighton, Colorado, which expires in May 2039 with an option to extend for two additional 5-year periods up to May 2049. When we signed the lease agreement in April 2023, we announced a plan to build a GWh-scale manufacturing facility in those premises. As of December 31, 2024, we completed our pre-construction planning for this facility. However, the scope and schedule of the construction of this facility will be determined based on, among other factors, the availability and timing of funding. In addition, we are currently monitoring the larger industry dynamics. Changes in demand, supply, battery cost structure, government incentives, trade tariffs, and other considerations may also influence our decision, including whether to proceed with the construction at all.

We believe that our facilities are adequate to meet our needs for the immediate future, and that, should it be needed, suitable additional space will be available to accommodate any such expansion of our operations.
