Amprius Technologies

Produces silicon-anode, high-energy lithium-ion cells

Overview

Amprius Technologies develops high-energy lithium-ion batteries using a silicon-anode cell that reaches about 500 Wh/kg, roughly twice the energy density of typical cells. The batteries store more energy per kilogram and per liter, and the cells are built into modules and packs to power devices, including electric vehicles, while prioritizing safety and cycle life. It differentiates itself with a patented silicon-anode technology, endurance records, and plans for a Gigawatt-hour-scale factory in Colorado to enable large-scale production. The goal is to become a leading supplier of high-energy, lightweight batteries for electric mobility and other applications, scaling manufacturing to meet growing demand.

Amprius Technologies Q3 earnings call highlights.

Amprius Technologies Q3 earnings call highlights. Amprius Technologies (NYSE:AMPX) raised its 2026 revenue target for the third consecutive quarter after reporting record third-quarter sales, but lowered its adjusted EBITDA outlook as it invests in product development, U.S. manufacturing and customer acquisition. The silicon-anode battery maker reported revenue of $39.1 million, up 83% from a year earlier and 15% from the second quarter. Chief Executive Officer Tom Stepien said demand came from a growing group of aviation, defense and advanced mobility customers. Amprius now expects 2026 revenue of $145 million, up from its prior forecast of at least $140 million. It lowered its adjusted EBITDA forecast to at least $2.5 million from more than $4 million, citing additional operating expenses to support projected demand. Revenue growth and margin outlook. North American revenue more than doubled year over year to $12.2 million in the third quarter, while European revenue was $23.3 million. Europe remained the company's largest market, accounting for nearly 60% of sales. Revenue for the first nine months of 2026 reached $101.7 million, up 113% from the same period a year earlier. Gross margin was 26.9%, compared with 27.3% in the second quarter and 15% a year earlier. Chief Financial Officer Ricardo Rodriguez said a greater mix of cylindrical cells and North American shipments reduced margin, as did the use of air freight to meet demand. Lower expenses in Fremont, California, and pricing helped offset those pressures, he said. Amprius reported a third-quarter net loss of $3.5 million, or 2 cents per share, compared with a loss 10% wider a year earlier. Adjusted EBITDA was negative $1 million. The company maintained its full-year gross margin forecast of at least 28%, which Rodriguez said implies a fourth-quarter margin of almost 35%. He pointed to an expected increase in higher-margin pouch cell sales, greater sales volume, pricing and a shift toward ocean freight as potential improvements. He said the freight benefit would mostly arrive in 2027. The revenue forecast implies fourth-quarter sales of about $43.3 million, roughly 11% above the third quarter. Rodriguez said the company was prioritizing margins and its path to profitability over pursuing additional near-term revenue. Amprius also reiterated its forecast for a 2026 net loss of $10 million or less and capital expenditures below $10 million. Rodriguez said the adjusted EBITDA outlook includes approximately $6 million of work expected to be completed in the fourth quarter under the company's $18.1 million Defense Innovation Unit agreement. That work is recorded as other income rather than revenue. Manufacturing expansion and defense demand. Stepien said Amprius is expanding its contract manufacturing network to meet demand while limiting capital spending. The company recently reached an agreement with CAMINUS to produce pouch cells in Indianapolis, with volume production targeted for the first quarter of 2027. Separately, Amprius received a $75 million competitive contract through the U.S. Department of War's Industrial Base Analysis and Sustainment Program to retrofit an existing domestic battery production line operated by a South Korean partner. Of the contract total, $22.3 million has been obligated, Stepien said. The conversion is expected to cost approximately $100 million, including in-kind investments from Amprius, and to be completed in early 2028. The company expects the line to have annual capacity of 12 million pouch cells. Stepien said the project is underway and that equipment delivery and factory work will likely become visible in the summer or fall of 2027. Amprius is already shipping cells compliant with National Defense Authorization Act sourcing requirements and remains on track for domestically produced compliant cells in 2027, Stepien said. He also said the company is discussing potential manufacturing arrangements in Europe, where some customers have expressed sourcing preferences. During the question-and-answer session, Oppenheimer analyst Colin Rusch noted that the company had raised its 2030 revenue target to $800 million from $600 million. Rodriguez said the additional $200 million was tied to expected capacity from the South Korean partner and CAMINUS, which together could add 270 to 300 megawatt-hours annually, depending on product mix. New products and markets. Amprius introduced its SiCore 500 cell in September for long-endurance aviation applications. Stepien said the cell, rated at 500 watt-hours per kilogram, is designed for standard lithium-ion manufacturing equipment and cell formats. The company plans to ship cells to high-altitude platform customers in the fourth quarter. Amprius also began shipping SiCore cells to a European manufacturer of autonomous deep-sea vehicles used in commercial, scientific and defense applications. Stepien said the vehicles operate at depths greater than 3,000 meters and called the subsea market a new growth opportunity. Looking ahead, Stepien said drones would still account for the dominant share of revenue in 2027, but he expects the business to become more balanced by 2030 as Amprius pursues applications including robotics and electric vertical takeoff and landing aircraft. Amprius ended the third quarter with $60.7 million in cash and no debt. Cash declined by $13.8 million during the quarter as the company funded capital spending and working capital, including advances to manufacturing partners to secure supply for late 2026 and 2027.

Amprius (AMPX) grows revenue 83 percent to 39.1 million dollars and raises its 2026 target to 145 million as US drone demand doubles.

Amprius (AMPX) grows revenue 83 percent to 39.1 million dollars and raises its 2026 target to 145 million as US drone demand doubles. Amprius Technologies reported third-quarter 2026 results on November 10. Revenue was a record $39.1 million, up 83% from $21.4 million a year earlier and 15% from the second quarter. The net loss narrowed to $3.5 million from $3.9 million. The stock fell after hours anyway. Invest in Stocks Amprius makes silicon anode lithium-ion batteries, which pack more energy into the same weight than conventional cells. That matters most where weight is everything: drones, aviation and defense. The US is the story. US revenue rose 2.3 times quarter over quarter to $12.2 million. Management ties that to defense and government programs, which fits the broader rush to build American drone supply chains. CEO Tom Stepien named drones, aviation, defense and advanced mobility as the markets where customer relationships deepened. Beat or miss depends on whose number. Estimates for the quarter varied. Revenue beat the $35.9 million consensus cited by one data provider and missed the $42.2 million figure used by another. The GAAP loss of $0.02 per share also landed on either side of expectations depending on the source. Mixed signals like that tend to produce a nervous reaction, which is what happened. Hire Accountants The operating trend is clearer. Gross profit was $10.5 million, and gross margin expanded about 12 percentage points to 27%. CFO Ricardo Rodriguez credits the company's model of owning the cell process while outsourcing manufacturing capacity, which lets it scale without building factories. Guidance. Amprius raised 2026 revenue guidance to $145 million from at least $140 million, slightly above the $140.6 million analysts expected. Revenue for the first nine months was $101.7 million, so the fourth quarter needs about $43 million, another sequential step up. Earlier in the year the company targeted a full-year net loss below $10 million and positive adjusted EBITDA of at least $4 million. Net losses for the first three quarters add up to about $13.6 million ($5.0 million, $5.1 million and $3.5 million), already past that earlier ceiling, and the third-quarter release didn't repeat the loss target. A company growing revenue 80% while nearly breaking even is in a strong position. Margins in the high twenties still leave little room for error if battery input costs rise.

Amprius introduces SiCore 500.

Amprius introduces SiCore 500. The second-generation SiCore platform is designed to achieve the same specific energy using existing manufacturing equipment, processes, and cell formats across Amprius' contract manufacturing network. Oct. 19, 2026 FREMONT, Calif. - Amprius Technologies Inc. introduced a silicon-anode lithium-ion battery cell rated at 500 watt-hours per kilogram (Wh/kg) for long-endurance aviation applications. The second-generation SiCore cell delivers the specified energy density at a continuous 1C discharge rate and is designed for production using conventional lithium-ion battery manufacturing equipment. The company said previous cells reaching 500 Wh/kg required specialized materials handling and nonstandard construction. The second-generation SiCore platform is designed to achieve the same specific energy using existing manufacturing equipment, processes, and cell formats across Amprius' contract manufacturing network. The cell targets high-altitude platform stations (HAPS), fixed-wing uncrewed aircraft, and other applications requiring extended flight endurance. Higher cell-level specific energy can reduce battery mass for a given energy capacity or provide more stored energy within a given weight limit, potentially increasing aircraft endurance, range, or payload capacity. Sponsored recommendations. Amprius has supplied batteries to AALTO, an Airbus subsidiary developing solar-electric HAPS aircraft, since 2018. The company's silicon-anode cells powered AALTO's Zephyr aircraft during a 2025 flight that lasted 67 days, 6 hours, and 52 minutes, setting an endurance record for continuous aircraft flight. Zephyr uses solar panels to recharge its batteries during daylight and stored electrical energy to sustain flight overnight. Amprius expects to make the second-generation SiCore cell commercially available in the fourth quarter of 2026. The company plans initial production at its Fremont facility, with volume production expected to expand through existing contract manufacturing partners. Cells are expected to be available in customer-specific configurations and a standard small uncrewed aircraft systems (sUAS) pouch format defined by SAE JA1016. Voice your opinion!
