## Overview

Amprius Technologies, Inc. develops, manufactures, and markets lithium-ion batteries built around a proprietary silicon anode platform. Its cells are designed for mobility applications that need very high energy density, high power density, and fast charging, with current demand centered on aviation and unmanned systems. The company has been commercially producing batteries since 2018 and says its silicon anodes can be used as a drop-in replacement for graphite anodes in conventional lithium-ion cells. Amprius sells both finished battery products and custom design/prototype services, and it also receives government grants from time to time. Its business model combines in-house pilot-line manufacturing in Fremont, California with outsourced contract manufacturing to scale output as customer demand grows.

## Customers

Amprius sells primarily to customers in aviation, unmanned aerial systems, and other mobility markets that need lightweight batteries with high energy and power performance. The company specifically cites customers such as AALTO Airbus, AeroVironment, BAE Systems, Kraus Hamdani Aerospace, Nokia Drone Networks, Nordic Wing, Teledyne FLIR, and the U.S. Army. Its customer base includes large enterprises and governmental agencies, which tend to require long qualification cycles, extensive testing, and acceptance provisions before volume orders begin. The company also serves drone and UAV manufacturers supporting tactical and commercial missions, where battery performance directly affects flight endurance, payload, and mission capability. Because many customers are still in qualification or development stages, Amprius often sells prototype batteries and custom designs before moving to higher-volume commercial shipments.

- **Aviation and aerospace customers** (primary) — Buy high-energy-density cells for aircraft, HAPS, and other airborne platforms where weight and endurance are critical.
- **Drone and UAV manufacturers** (primary) — Buy SiCore and related cells for commercial and tactical drones that need high power, fast charging, and long flight time.
- **Defense and government agencies** (secondary) — Buy batteries and development support for mission-critical applications that require validated performance and reliability.
- **Mobility and electric transportation developers** (emerging) — Evaluate Amprius technology for broader EV and light electric vehicle applications as the platform matures.

- Large enterprises that demand extensive testing and acceptance before scale-up

## Geography

Amprius is headquartered in Fremont, California and conducts key manufacturing and pilot-line work there. The company previously leased a large Brighton, Colorado facility for planned scale manufacturing, but in 2025 it recorded impairment charges and later agreed to terminate that lease, reflecting a shift toward outsourced contract manufacturing. Management says it can serve customers through existing contract manufacturers as orders move from qualification to higher volume. The business is exposed to global supply-chain and tariff dynamics because some batteries and production equipment are manufactured in China, while customer demand and manufacturing partners can span multiple regions. The reports do not provide a country-by-country revenue split, so the geographic profile is best understood through operating footprint and supply-chain exposure rather than disclosed revenue concentration.

- Fremont, California is the core operating and pilot-manufacturing site
- Brighton, Colorado was planned for scale manufacturing but is being exited
- Contract manufacturing supports customer deliveries at higher volumes
- China is relevant as a source of batteries and production equipment
- Customer and partner exposure is global, especially in aviation and defense
- No country-level revenue breakdown was disclosed in the excerpts

## Strategy

Amprius is focused on commercializing its silicon-anode battery technology in applications where performance matters more than commodity pricing. A central priority is to expand manufacturing capacity without heavy capital intensity by using a mix of Fremont pilot production and global contract manufacturers. The company is also pushing customer qualification and product validation, since large enterprise and government buyers typically require extensive testing before placing volume orders. Management is investing in higher-output battery platforms such as SiCore and optimizing SiMaxx production to support future scale. The strategy is to convert technical differentiation into repeatable commercial shipments while keeping manufacturing flexibility and funding needs manageable.

- **Expand commercial production through outsourced manufacturing** (short-term) — This lets the company meet demand faster while avoiding the cost and timing risk of building all capacity internally.
- **Accelerate customer qualification and validation** (short-term) — Large aerospace, defense, and drone customers require proof of performance before committing to volume purchases.
- **Broaden adoption beyond aviation into wider mobility markets** (medium-term) — A larger end-market base would reduce dependence on a narrow set of early adopters and improve long-term growth potential.

- Scale commercial shipments of SiCore batteries into aviation and UAV markets
- Use contract manufacturing to expand capacity with lower capital investment
- Optimize Fremont pilot-line output to accelerate customer qualification
- Develop and validate high-energy platforms such as SiMaxx and SiCore
- Convert prototype and design engagements into higher-volume orders
- Pursue government-supported manufacturing expansion where available

## Risks

Amprius faces execution risk because its batteries must perform reliably in demanding applications, and any failure could damage customer adoption and reputation. The company also depends on third parties for certain battery manufacturing and materials, which creates supply, quality, and cost risks that are especially important in a scaling hardware business. Building high-volume manufacturing lines is technically difficult, and the company may not achieve the required yield, throughput, or cost targets needed for profitability. Its exposure to tariffs, China-sourced equipment, and geopolitical disruptions can affect input costs and supply continuity, while large-customer sales cycles can be long and uncertain. As a battery manufacturer, it also faces product liability, safety, cyber, and equipment-uptime risks that can materially disrupt operations.

- **Product performance risk** [high] — If the batteries do not meet promised energy density, power, or charging specifications, customers may not adopt or reorder.
- **Third-party manufacturing and supply-chain dependence** [high] — The company relies on external manufacturers and suppliers for certain batteries, materials, components, and equipment.
- **Manufacturing scale-up risk** [high] — High-volume lines may fail to achieve required quality, yield, throughput, or cost structure.
- **Geopolitical and tariff exposure** [medium] — Some batteries and production equipment are manufactured in China, and tariffs or trade restrictions could raise costs.
- **Cybersecurity and data security risk** [medium] — The company stores partner and customer information and has experienced a ransomware incident in the past.

- Battery performance failures could reduce customer trust and future sales
- Dependence on third-party manufacturing and suppliers can disrupt supply and quality
- High-volume manufacturing may miss yield, throughput, or cost targets
- Tariffs and China-linked sourcing can pressure margins and availability
- Long enterprise and government sales cycles can delay revenue conversion
- Battery safety, recalls, and liability claims could be costly
- Cybersecurity incidents could expose proprietary data and interrupt operations

## Accounting

Amprius recognizes revenue at a point in time, generally upon shipment for finished battery products and upon completion or delivery for custom prototype work, so shipment timing can materially affect quarterly results. Revenue also includes government grants when there is reasonable assurance of compliance and receipt, which adds judgment around timing and classification. The company’s mix of product sales, customization services, and grants can make quarter-to-quarter revenue less comparable because each stream follows different recognition triggers. Lease accounting is important because the Brighton facility lease was impaired and then terminated, creating charges tied to right-of-use assets and construction-in-progress. As a smaller reporting company and emerging growth company, Amprius also relies on estimates and assumptions that can affect reported results, especially around manufacturing assets, impairment, and future capacity decisions.

- **Point-in-time revenue recognition** — Quarterly revenue and gross margin comparability
- **Government grant accounting** — Revenue and other income volatility
- **Lease impairment and termination** — Operating results and balance sheet assets
- **Manufacturing asset and construction-in-progress impairment** — Non-cash charges and future capacity assumptions

- Revenue is recognized on shipment or delivery, so timing of orders affects quarterly results
- Custom design/prototype revenue depends on completion milestones and customer acceptance
- Government grants require judgment on compliance and expected receipt
- Lease impairment and termination costs affect operating results and asset values
- Construction-in-progress and manufacturing asset impairment are judgmental estimates
- Quarterly results can swing with product mix, customer qualification timing, and grant recognition
