• Changes in other domestic and foreign business, market, financial, political, and legal conditions.

Future Outlook

Amprius Technologies expects continued growth by broadening its product portfolio, converting customer engagements into formal qualifications and deployments, and leveraging contract manufacturing partners for scaling demand. The company plans to strategically invest in diversifying its supply chain and expanding electrode manufacturing capacity at its Fremont facility, largely covered by the $12.0 million DIU contract. The decision on the Colorado facility expansion remains contingent on market dynamics, funding, and government incentives, with current capacity needs met by contract manufacturers.

Management Comments

• "Amprius finds itself at a very fortunate point in time: at the intersection of a fast-growing electric aerospace market with an industry-leading set of battery products."
• "This advantaged situation, coupled with strong execution by our team, allowed us to achieve record revenue in the third quarter."
• "We believe this strong and expanding customer traction comes from the superior performance our batteries offer compared to traditional cells."
• "This enhanced endurance doesn't just improve performance; we believe it redefines what's possible in every mission and can mean the difference between success and failure." (Regarding Nordic Wing's Astero ISR)
• "Amprius offered the best combination of advanced battery technology, production readiness, and cost competitiveness to meet the demands of this program." (Andrew Gibson, CEO and President of ESAero, quoted by Amprius)
• "Ricardo has a proven track record of driving growth with financial discipline in high-performance markets and he will serve as a valuable guide as we expand our commercial reach, scale global manufacturing, and reinforce Amprius leadership in advanced battery technology."

Industry Context

The announcement highlights Amprius's strong position within the rapidly expanding electric aerospace market, estimated by McKinsey to grow from $40-50 billion to $80 billion by the end of the decade. The company is capitalizing on increased defense and commercial demand for AI-driven autonomy, particularly in the Unmanned Aerial Systems (UAS) sector, which accounts for 75% of its Q3 revenue. Regulatory tailwinds, such as U.S. executive orders promoting domestic drones and proposed changes to Beyond Visual Line of Sight (BVLOS) rules, are expected to accelerate market adoption. Amprius's focus on high-energy and high-power density silicon anode batteries positions it as a key enabler for longer endurance and greater payload capacity in these advanced aerial platforms, differentiating it from traditional battery manufacturers.

Comparison to Industry Standards

• Amprius's silicon anode cells offer 450 Wh/kg specific energy density and 1,150 Wh/L volumetric energy density, commercially available since early 2022, which it believes no other commercially available lithium-ion batteries can match.
• The company has third-party validated a 500 Wh/kg, 1,300 Wh/L battery platform, setting a high benchmark for energy density.
• Its batteries achieve an extreme fast charge rate of 0-80% state of charge in about six minutes, a competitive advantage for rapid deployment applications.
• The SiCore cells chosen by Nordic Wing for their Astero ISR UAV platform resulted in 90% longer flight time compared to standard cells, demonstrating superior performance in a real-world application.
• The company's safety design features enable it to pass the United States military's benchmark nail penetration test, indicating robust safety standards.
• Amprius's SiCore standardization allows contract manufacturing partners to produce silicon cells on the same line using the same equipment as conventional graphite cells, suggesting a more efficient and scalable manufacturing process compared to potentially specialized production lines for other advanced battery chemistries.
