Amprius’ State-of-the-Art Gigawatt-Hour Scale Factory in Colorado Passes Major Milestone

Amprius On Track to Operationalize its Growth Engine to Serve Strong Customer Demand for High-Performance Silicon Anode Lithium-Ion Batteries and Fuel the Electric Mobility Market

Amprius Technologies, Inc. (“Amprius” or the “Company”) (NYSE: AMPX), a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, today announced that the Brighton City Council approved an ordinance to rezone an approximately 103 acre site, including an existing 1,278,455 square foot facility, to allow, among other matters, the Company to manufacture its next-generation lithium-ion batteries. This marks a significant milestone clearing the path for Amprius to establish its state-of-the-art gigawatt-hour scale factory site to meet growing customer demand.

"This approval from the Brighton City Council marks an important step towards our goal to begin operations at Amprius Fab in the first half of 2025,” said Dr. Kang Sun, Chief Executive Officer of Amprius. “Establishing the first silicon anode battery production facility in Brighton, Colorado, represents a pivotal milestone for the United States in building a local ecosystem that advances electric mobility. We thank the City of Brighton staff and City Council for all their dedicated work and efforts in handling the rezoning application. Additionally, we extend our appreciation to the community members who participated in the process.”

With this project, Amprius aims to repurpose a significant portion of Colorado’s largest single-story industrial building and transform it into a state-of-the-art lithium-ion battery manufacturing facility. This factory site is expected to greatly increase Amprius’ manufacturing capacity, with an initial 500 megawatt-hours (MWh) and the potential of up to 5 gigawatt-hours (GWh) available within the existing footprint. The projected timeline for the factory site is between 18–24 months.

After conducting an exhaustive nationwide search, Colorado emerged as the most compelling location for the Company due to its proximity to key suppliers, highly skilled workforce, and the unwavering support of both the City of Brighton and the State of Colorado. Amprius looks forward to providing generational opportunities by creating more than 300 new local jobs, investing $190M in Phase 1 with more phases to follow and partnering with local universities and high schools in developing their STEM programs. Today’s pivotal rezoning underscores a firm commitment to Colorado's vision of becoming a trailblazer in the clean energy sector, which encompasses battery manufacturing, wind, and solar industries.

“We have been partnering with Amprius through the evaluation and design phase for pre-construction services for over 9 months,” said Scott D. Bulera, Vice President / General Manager of Industrial & Advanced Manufacturing - EV / Battery at Turner Construction Company. “We have the teams ready to execute on the plan.”

This is the second expansion initiative undertaken by Amprius. Exiting 2023, Amprius Labs expected to provide 10x capacity to serve existing customers and new customer qualifications and de-risking the Company’s expected growth starting in 2025. The first phase of the capacity will be focused on the aviation sector, estimated to be over $49 billion in battery demand by 2025.
