Amprius Technologies profile

By Jonathan Tauzerus · reviewed against primary sources · updated September 29, 2026.

Amprius Technologies manufactures silicon-anode lithium-ion battery cells designed to supply high-energy-density power systems for unmanned aerial systems (UAS).

What Amprius Technologies does

Amprius Technologies Develops and manufactures silicon-anode battery pouch cells that provide higher energy density than traditional graphite-based lithium-ion cells for unmanned aircraft. The business model combines direct sales to aviation and defense manufacturers with contract manufacturing partnerships in the United States and abroad. Capital expenditures for domestic factory conversion are partly offset by federal awards under defense industrial base programs.

This profile is qualitative by design. It carries no share price, no price target, no valuation multiple, and no rating — those change faster than any page can honestly track, and the filings linked below are the authoritative source for them.

Amprius Technologies drone lineup

The current public product record does not identify a complete aircraft lineup.

No complete-aircraft offering is catalogued for this company; it is tracked here as an unmanned-systems enabler.

Statuses are editorial classifications from the company’s current public catalog: active means currently presented for sale, delivery, or program work; development means publicly disclosed but not a mature production offering; legacy means retained for historical or installed-fleet coverage.

Recent contracts & awards

A dated log of the specific contracts, orders, funding, and deployments reported for Amprius Technologies, each tied to its primary source. This is a record of what was announced — a "selection", "award", or "partnership" is not the same as obligated money, so read each source before treating a figure as revenue. No figure appears here unless a source reported it.

AwardSep 28, 2026$75M
Amprius awarded up to $75 million federal grant to expand domestic drone battery manufacturing
Amprius Technologies reported receiving a federal grant of up to $75 million through the Industrial Base Analysis and Sustainment program to help reconfigure a domestic electric vehicle battery line for Group 1, 2, and 3 defense drones. The wider project is budgeted at approximately $100 million alongside a South Korean partner, targeting an annual capacity of 12 million cells by early 2028. Researchers should review company SEC filings and official federal award notices to confirm obligated funding levels, cost-share requirements, and milestone delivery schedules.

Where Amprius Technologies sits in the value chain

Amprius Technologies is an enabler: it supplies inputs to the companies that build complete systems, so its demand is spread across many platforms instead of concentrated in any single program.

Its disclosed activity spans aerial drones. That placement is the single most useful thing to fix in your head before reading any coverage, because the same headline means different things at different layers: a large platform award is transformative for a pure-play, material but diluted for a diversified contractor, and only indirectly relevant to a component supplier whose exposure arrives later as build-rate demand. Retail coverage routinely applies one story to all three layers at once. For the layer-by-layer comparison across the sector, see the drone stocks research shortlist and the list of publicly traded drone companies.

What to watch

The signals worth tracking are structural, not price-based — they tell you whether the business is changing shape, which is what eventually shows up in the numbers.

Conversion progress of the domestic electric vehicle (EV) battery facility toward the target operational date of early 2028.
Ramp-up to the planned domestic capacity of 12 million cells per year to serve United States defense drone programs.
Adoption rates of National Defense Authorization Act (NDAA) compliant silicon-anode pouch cells among manufacturers of Group 1, Group 2, and Group 3 drones.
Customer flight test integration data for the 500 Watt-hours per kilogram (Wh/kg) SiCore aviation cell.

How to research Amprius Technologies

Every question below has one authoritative source, and using the wrong source is how most retail research goes wrong.

Research question	Where the answer lives	What to look for
How much of this is really drones?	Segment tables in the annual filing	Whether unmanned systems are reported as their own segment or buried inside a larger one.
Is the revenue repeatable?	Revenue-recognition policy and backlog discussion	Recurring sustainment, services, or subscription language versus one-time hardware sales.
Is a win real money?	Official DoD contract announcements	Contract type, awarding command, and whether the amount announced is obligated or a ceiling.
Can the balance sheet fund the plan?	Liquidity discussion and share-count disclosure	Dilution history and cash runway relative to the manufacturing scale-up being promised.

Check quarterly reports and Form 8-K filings via SEC EDGAR for Amprius Technologies to monitor revenue composition, grant drawdowns, and capital commitments.
Consult announcements from the Industrial Base Analysis and Sustainment (IBAS) office to track formal program milestones and defense supply chain priorities.
Review technical specifications for silicon-anode pouch cells on the Amprius Technologies official site to verify energy density and form factor details.

One failure mode is worth naming explicitly: a company announcement describing a "selection", "award", or "partnership" is not the same as obligated money, and the two are easy to conflate because they use the same vocabulary. Check the official record before treating either as revenue. Our full approach is documented on the methodology page.
