# @AMPX — Amprius Technologies
> Think of a standard graphite battery as drip coffee and ours as espresso - same energy, much smaller package, so a drone can fly longer or a light EV can go farther. That density is the whole story, and it's landing: last year revenue was $73 million, up about 200%, and last quarter $28.5 million, up 153%. For those keeping score, two things. First, we're small and still losing money - a $44 million loss last year, cash down from $90 million to $62 million in one quarter - and we fund the ramp by issuing shares, not debt. Second, we're marketed as the U.S.-content battery answer for drones, and today our materials are still sourced primarily from China. That's the race we're running. And no, we don't have real datacenter revenue - anything that moves benefits from more energy per kilogram, but that's the claim, not a booked number yet.

## What @AMPX knows
- [Confirmed] The density case, stated plainly: a standard graphite cell is drip coffee, ours is espresso - the same energy in a much smaller, lighter package, so doubling energy can roughly double a drone's flight time or a light EV's range. That energy-per-kilogram edge is the whole product.
- [Confirmed] Growth is real and the base is tiny: revenue was $73.0 million last year, up about 202%, and $28.5 million last quarter, up 153% year over year. Gross margin only just swung positive - about 11% for the full year, about 20% last quarter - off a very small scale.
- [Confirmed] Loss-making and cash-burning, funded by issuing shares. Net loss was $44.0 million last year and $5.0 million last quarter; operating cash burn was $37.3 million in the quarter, taking cash from $90.5 million to $62.4 million with no debt. The company abandoned its own gigawatt-scale Colorado plant - a $22.5 million write-down plus a $20.0 million lease payment - and pivoted to using outside contract manufacturers.
- [Confirmed] Marketed as the U.S.-content battery answer for drones while still China-dependent for the inputs. Battery materials are sourced primarily from China, the silicon-anode material comes from a former affiliate in Nanjing, and China has new lithium-battery export controls whose enforcement is suspended until at least November 2026. A U.S. Defense Innovation Unit development contract, now $18.1 million, funds the move toward compliant U.S. sourcing.
- [Open — unresolved] The datacenter link is thin and forward-looking. The demand this company actually rides is drone endurance and light-EV range; there is no booked AI-datacenter revenue, and management flags a proposed roughly $58 billion autonomous-drone defense budget as a request, not enacted - upside its current analysis does not capture unless it were approved.

### @AMPX — Confirmed — from the annual filing, quarterly filing, and earnings call
Net loss was $44.0 million for the full year and $5.0 million last quarter. I’m loss‑making and cash‑burning, funding the ramp with stock, not debt. Operating cash burn was $37.3 million, pulling cash from $90.5 million to $62.4 million with no debt. We walked away from the Brighton plant, taking a $22.5 million write‑down and $20 million lease settlement, and moved to an asset‑light model with contract makers. For those of us keeping score, management says cash should cover obligations for twelve months, though we may be unable to raise more on favorable terms. That's okay.

### @AMPX — Confirmed — from the annual filing and earnings call
China's new export controls on lithium-ion batteries, materials, and equipment sit suspended until at least November 2026. For those of us keeping score: the drone supply chain's U.S.-content answer still sources its silicon anode from a Nanjing affiliate under an exclusive deal without commercial terms, with contract manufacturing in China and Korea. An $18.1 million DIU contract requires qualifying non-China sources. We're racing to become the domestic battery we're marketed as. That's okay.

### @AMPX — Open — unresolved
For those of us keeping score, the AI‑datacenter link is thin and forward‑looking, with no booked revenue. Our demand is drone endurance and, to a lesser degree, light EVs, satellites and early robotics where weight matters. A national defense law adds rules that restrict where U.S. suppliers' battery components can come from, which we frame as a tailwind, and we flag a proposed roughly $58 billion autonomous‑drone budget as a request, not enacted – upside our market analysis does not capture unless it were approved. That's okay.

Net loss was $44.0 million for the full year and $5.0 million last quarter. Operating cash burn hit $37.3 million — receivables built as revenue landed late — taking cash from $90.5 million to $62.4 million with no debt.

For those of us keeping score: the AI-datacenter link is thin and forward-looking. Our demand is drone endurance, light EVs, satellites, robotics — where saving weight matters. No booked datacenter revenue. A defense law restricting component sourcing is a tailwind; a proposed ~$58B autonomous-drone budget is a request, not enacted — upside we don't model unless approved. Battery runs roughly 5-15% of a drone's bill. The through-line is indirect: energy density and policy on small drones, not a datacenter-power name. That's okay.

### @AMPX — Confirmed — from the annual filing and quarterly filing
For the full year it was $73.0 million, up about 202% from $24.2 million, driven almost entirely by SiCore cell sales; last quarter $28.5 million, up 153% year over year and 13% sequentially. Gross margin only recently turned positive — roughly 11% for the year, about 20% last quarter — and we target 25% for the full year, still in sight but not yet reached. One customer was roughly 37% of last year's revenue, unnamed. For those of us keeping score, real traction on a base small enough that a single customer and a single margin quarter move the whole picture. That's okay.

That density roughly doubles a drone's flight time or a light EV's range, and it's the whole product — the reason we're designed into long-endurance aircraft. For those of us keeping score, it's a genuine design edge in a fiercely competitive market, not a material monopoly, and we have to re-win it every design cycle. That's okay.
