Prepared Metrics

Q&A Batch (1–5 of 5)

Q1 — Eric Stine

• Topic: 电池组件选择进展与Gauntlet无人机计划
• Key points:
  • 已选定阳极、阴极、电解质、隔膜等11个组件，包含主/次级供应商，测试始于2025年7月DIU项目，历时6–8个月；部分组件性能略优于旧版。
  • 剩余工作：产品化、签署多年协议（包括在韩国、日本、美国寻找供应商），并交付至合同制造商，以满足客户大规模需求。
  • Gauntlet无人机计划首批25家受邀者已完成飞离测试，预计近日公布筛选结果；后续还有第二、三、四轮，持续约18个月。
• Mgmt stance: 中性偏积极——技术环节已基本完成，转向供应链和运营落地；无人机方面虽有不确定性，但已深度参与。

Q2 — Austin Volle

• Topic: 新客户增长与地理分布展望
• Key points:
  • 客户总数从11月的444增至550，其中Q4新增超100个新客户；大部分新客户处于评估阶段（订购数百颗电池做测试），平均订单金额环比Q3增长。
  • 2026年指引假设地理结构与去年Q2/Q3类似（欧洲/国际仍是主要收入来源），美国订单尚未充分计入，若美国需求启动可带来上行。
• Mgmt stance: 谨慎乐观——早期阶段但客户增长和订单金额均有改善，美国市场是潜在弹性来源。

Q3 — Mark Schubert

• Topic: 地缘政治引发的紧急需求与NDAA合规产能布局
• Key points:
  • 过去周末有单个客户因伊朗战事导致自身无人机订单加速，从而向公司紧急下单，试点线可在数周内交付。
• NDAA合规需求下，客户希望了解美国本土产能时间表；现有合作伙伴Nanotech提供圆柱电池，另有更多合作在推进。预计未来几年需求将分为约1/3（韩国、非敏感）、1/3（美国）、1/3（其他）。
• Mgmt stance: 积极——真实紧急订单出现，产能（试点线+合作伙伴）可应对短期与中期需求。

Q4 — Colin Rusch

• Topic: 技术路线图（阴极瓶颈）与市场规模及增长节奏
• Key points:
  • 当前能量密度瓶颈主要在阴极（不是阳极），公司已向董事会报告具体改进目标，重点通过测量和研发提升。
  • 测试体系较完善：小规模手动线+30台由国防部资助的新设备正在到位。
  • 市场规模（Slide 4）及内部目标（Slide 7）显示，即使在目标市场增速减半的情况下，公司仍有$600M+能力，取决于产能部署位置。
• Mgmt stance: 乐观——技术优势可防御，市场空间巨大，自身产能规划足够覆盖。

Q5 — Ryan Pfingst

• Topic: 航空/无人机市场份额与2026年指引细节
• Key points:
  • 当前无人机电池市场份额为个位数（未精确数字），分类为1–5级，公司产品主要用于1、2及3级的一半。在高功率、高能量密度无人机（如侦察、复杂任务）中份额较高，而低价无人机（用遥控车电池）不是目标市场。
  • 2026年指引基线收入基于现有客户及预期Q3/Q4新转化客户，未充分计入美国本土无人机生产带来的额外需求；需等待PO确认后再量化上行空间。
• Mgmt stance: 中性偏积极——强调份额取决于细分市场，在高端领域已有优势；美国需求正快速演变但需以订单为准。

Q&A Batch (6-10 of 10)

Q6 — Ted Jackson

• Topic: SiMax to SiCore product transition revenue mix
• Key points:
  • SiMax revenue at the beginning of the year was 25% of total.
  • Management sees SiMax revenue at zero by 2026.
• Mgmt stance: Neutral/Decretive — clear timeline for phasing out legacy SiMax, but transition is ongoing.

Q7 — Thomas Stepien

• Topic: Competitive positioning and customer relationship status
• Key points:
  • Management considers itself near the front of the market but notes all battery manufacturers have "gotten the memo."
  • On Slide 4, "key market players" include: publicly announced customers, potential customers in testing, and others where trust must still be earned.
  • Ricardo Rodriguez added that all listed companies are logical buyers, and some have purchased low-volume testing cells.
• Mgmt stance: Neutral/Cautious — bullish on own technology lead, but acknowledges competition and need to earn trust from potential customers.

Q8 — Derek Soderberg

• Topic: Nokia partnership and competitive advantage in drones
• Key points:
  • Nokia uses the platform to beam 5G to hard-to-reach areas.
  • Amprius batteries enable Nokia drones to fly 40%-50% longer; other customers achieve twice the flight time vs. standard batteries.
  • Management does not break out specific customer volumes.
• Mgmt stance: Bullish — emphasizes "espresso advantage" of energy density as key reason for customer wins.

Q9 — Thomas Stepien (continued from Q8)

• Topic: Growth acceleration strategy
• Key points:
  • Execution focus: operational side (delivery, timing, location), expanding sales team, and a growing "pack partner program."
  • Cells go directly to end-use product makers (drones, robots) or through pack houses.
• Mgmt stance: Neutral/Bullish — investing in customer-facing processes and capacity to meet demand, but execution is key.

Q10 — Chip Moore

• Topic: Battery replacement market and adjacencies (data center, military)
• Key points:
  • For eVTOL
