Amprius Technologies Inc.

Amprius Technologies raised its full-year 2026 revenue guidance to at least $140 million, up from a prior forecast of at least $130 million, after reporting record second-quarter revenue of $34.0 million, up 19% from the first quarter and 2.3x year-over-year. Gross margin improved to 27% from 20% in the first quarter and 9% a year ago, driven by a favorable product mix, and the company now expects full-year gross margins of at least 28%, raised from a previous target of 25%. SiCore batteries accounted for 98% of second-quarter sales, with EMEA contributing 68% of total revenue, fueled by demand from European drone manufacturers. The company also announced a three-year supply agreement with Stark Future for electric motorcycles, expected to generate at least $100 million in revenue through 2029, and a $24 million order from a new European drone customer for SiCore cylindrical cells. Amprius ended the quarter with $74.5 million in cash and no debt, and it reiterated its target of positive adjusted EBITDA of at least $4 million for the full year.

Retail investors on Reddit are favoring Amprius Technologies over SpaceX, citing significant upside potential for the battery maker. Amprius, which produces silicon-anode batteries for drones, satellites, aerospace, and robots, has seen its stock rise 55% this year. The company's batteries offer higher energy density, enabling longer drone flights and lighter, cheaper satellite launches. First-quarter revenue surged 150% year-over-year, while trailing 12-month revenue tripled, and 2026 revenue guidance indicates 78% growth.

Amprius Technologies reported first-quarter revenue of $28.5 million, a roughly 2.5-fold increase year over year, and management raised its 2026 revenue guidance to at least $130 million. The company develops silicon-anode lithium-ion batteries for drones, aviation, defense, and high-altitude platforms, offering higher energy density than conventional batteries. Strategic partnerships, including a manufacturing collaboration with Nanotech Energy and a relationship with Matternet, support domestic production scale and demand visibility in drone logistics. Amprius remains unprofitable and faces execution risks as a small-cap company, but recent revenue growth and deal flow suggest it is beginning to de-risk its commercial trajectory.
