FREMONT, Calif.--(BUSINESS WIRE)-- 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 in 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 preconstruction 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.
