Distinguished Lineup of Experts to Address Amprius’ Leading the Future of Electrification with Next-Generation Battery Technology at the Company’s Fremont, CA Headquarters

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 a distinguished lineup of experts from AALTO Airbus, AeroVironment, and centrotherm will present on Amprius’ battery integrations and capabilities at the Company’s production capacity expansion ribbon-cutting event.

Amprius is hosting a select group of customers, vendors, investors, and partners to showcase its new MWh-scale silicon nanowire anode battery production facility in Fremont, California, known as Amprius Lab, on December 14, 2023. Amprius is substantially bolstering its Fremont facility from kWh to MWh capacity this year – a 10x increase in production exiting 2023 to further serve existing customers and supply the backlog of new customers seeking high performance cells.

The invite-only event will include keynote speakers from Airbus subsidiary AALTO HAPS, aerospace and defense contractor AeroVironment, and leading technology & equipment provider centrotherm.

Presentation highlights and speakers:

• AALTO HAPS – AALTO Zephyr – Working Together Towards a Stratospheric Future, presented by Tom Owen, Power System SME at AALTO HAPS Ltd.
• AeroVironment – Switchblade Loitering Munitions: AeroVironment’s Partnership with Amprius, presented by John Aldana, Sr. Director, Switchblade 300 Product Line Loitering Missile Systems at AeroVironment
• centrotherm – Development of CVD-Production Equipment for Advanced Electronic Devices in Commodity Markets, presented by Helge Haverkamp, CTO at centrotherm

“This is a critical milestone as we showcase our successful scale from kWh to MWh capability on our journey to GWh scale in 2025. The facility in Fremont, CA not only adds additional production capacity to serve customers, but also provides our engineering team with a tool to optimize manufacturing processes for our industry leading technology,” said Dr. Kang Sun, CEO of Amprius.

During the event, invitees can also engage Amprius executives on the expansion’s impact and observe the state-of-the-art manufacturing equipment. All-new assembly and dry rooms will be available for viewing – along with silicon anode mass production equipment, the same technology planned for the GWh factory in Colorado.

Amprius’ cells power products from these renowned companies, along with other leading mobility and defense partners, and are well positioned to support the fast-growing aviation and, eventually, electric vehicle markets, estimated to be collectively over $100 billion in battery demand by 2025.
