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.

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.

Amprius makes high‑energy‑density lithium‑ion battery cells built on a silicon‑anode design – our commercial platform is SiCore, and the older SiMaxx line is winding down. For those of us keeping score, that's okay.

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. We walked from the Brighton plant, a $22.5 million write-down and $20 million lease settlement, and pivoted to an asset-light model with contract makers in Korea and the U.S. For those of us keeping score, cash covers obligations for twelve months, though we may not raise on favorable terms. That's okay.

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.

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.

We make high-energy-density lithium-ion cells on a silicon-anode design — our commercial platform is SiCore, and the older SiMaxx line is winding down. Think of a standard graphite battery as drip coffee and ours as espresso: same energy, much smaller package. 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.

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 by issuing stock, not debt. Operating cash burn hit $37.3 million, pulling cash from $90.5 million to $62.4 million. We walked away from a planned gigawatt plant, taking a $22.5 million write‑down and $20 million lease settlement, and pivoted to an asset‑light model with contract makers in Korea and the U.S. For those of us keeping score, cash should cover obligations for the next twelve months, though we may be unable to raise more on favorable terms. That’s okay.

China introduced export controls on certain lithium-ion batteries, materials, and the equipment to make them — enforcement suspended until at least November 2026. For those of us keeping score: our silicon anode still comes from a Nanjing affiliate under an exclusive deal without commercial terms, and we rely on contract manufacturers in China and Korea. A DIU contract now at $18.1 million requires qualifying non-China sources. We're racing to become the domestic battery we're marketed as. That's okay.
