Amprius Technologies (AMPX) Q1 2024: Customer Shipments Double as Sitecore Drives Capacity Scale
Amprius Technologies doubled its customer shipments in Q1 2024, propelled by the commercial launch of its Sitecore battery platform and expanded toll manufacturing agreements. The company is prioritizing rapid capacity scale and customer qualification to capture surging demand in electric mobility, while balancing margin pressure and capital allocation for its Colorado gigafactory build-out. Management’s focus on Sitecore reflects a pragmatic shift to near-term volume, but the market will scrutinize execution on both product differentiation and cost normalization as expansion unfolds.
Summary
- Customer Expansion Surges: Shipments to 82 customers, with 52 new, validate broadening demand across aviation and mobility.
- Capacity Strategy Shifts: Sitecore prioritized for initial Colorado production line, leveraging toll manufacturing to accelerate revenue scale.
- Margin and Cost Normalization: Negative gross margins persist as startup costs and product mix weigh, with normalization dependent on future scale.
Business Overview
Amprius Technologies develops, manufactures, and markets high-performance silicon-anode lithium-ion batteries for electric mobility, specializing in aviation and electric vehicle (EV) applications. Its two primary product lines are CEMEX, high energy density batteries for demanding aerospace use cases, and Sitecore, a new platform targeting high energy density with longer cycle life and broader form factors for micro-mobility and e-bike markets. The company generates revenue from product sales and, to a lesser extent, development services and grants, with a strategy centered on scaling proprietary manufacturing and leveraging contract production to meet growing demand.
Performance Analysis
Amprius delivered $2.3 million in product revenue in Q1 2024, representing a 397% year-over-year increase and a 147% sequential rise, driven by a surge in shipments to 82 customers—up from 41 in Q4 2023. This expansion was powered by the commercial introduction of the Sitecore platform, which accounted for the majority of new customer shipments and enabled Amprius to address a broader range of applications through contract manufacturing partnerships.
Despite the topline acceleration, gross margin remained sharply negative at -190%, reflecting the combined effects of factory startup costs, low initial scale, and a transitional mix of product and service revenue. Operating expenses were managed flat sequentially and down 6% year-over-year, but net loss remained at $9.9 million, unchanged on a per-share basis. The company ended the quarter with $39 million in cash and no debt, supported by proceeds from its at-the-market (ATM) equity facility.
- Customer Diversification Accelerates: Only three customers represented more than 10% of revenue, signaling broadening end-market adoption.
- Sitecore Drives Volume: 76 of 82 customer shipments were Sitecore, reflecting the platform’s role in near-term scaling.
- Manufacturing Ramp Remains in Early Stages: Fremont facility qualification and Brighton gigafactory design are progressing, but capacity remains limited until later in 2024.
Management’s approach to capacity—balancing toll manufacturing for Sitecore with in-house ramp for CEMEX—positions Amprius to address immediate demand, but sustainable margin improvement hinges on successful execution of its Colorado plant and operational scale-up.
Executive Commentary
"In Q1, we doubled the number of customers we shipped to over Q4, 2023, shipping to 82 customers, up from 41. 52 of these shipments were to new customers across the electrical mobility sector, complementing our strong repeat customer base that includes Auto, Airbus, Teladon, FLIR, the US Army, and BAE Systems."
Dr. Kang Sung, CEO
"Our gross margin was negative 190% for the quarter, compared to negative 518% in the prior year period, and negative 98% in Q4 of 2023. As a reminder, we see significant gross margin variation as our product and services revenue mix fluctuates."

Strategic Positioning
1. Sitecore Platform as Scaling Catalyst
The launch and rapid commercialization of Sitecore, Amprius’s new high-cycle-life battery, is central to its 2024 scaling strategy. Sitecore leverages existing lithium-ion production capacity via toll manufacturing, enabling Amprius to meet demand without immediate capital outlay and to serve a wider set of applications, including e-bikes and micro-mobility.
2. Manufacturing Model Flexibility
Amprius’s dual-track manufacturing approach—toll manufacturing for Sitecore and in-house ramp for CEMEX—offers flexibility but introduces operational complexity. The decision to redesign the initial Brighton, Colorado, line for Sitecore reflects pragmatic prioritization of near-term volume, with CEMEX capacity expansion deferred to subsequent lines as demand and process validation mature.
3. Customer and Market Diversification
Q1 saw significant customer diversification, with 52 new customers and broadening geographic reach across the US, Europe, and Asia. Strategic partnerships with Airbus, the US Army, and new entrants like AI Bots and Stafl Systems signal growing traction in both established and emerging electric mobility segments.
4. Capital Allocation and Funding Pathways
Amprius is actively managing capital through a combination of ATM equity issuance, grant pursuit, and disciplined opex. The company expects to provide a detailed cost forecast for the Brighton gigafactory after completing construction drawings by the end of summer, with additional funding sought via both dilutive and non-dilutive sources.
5. Product Differentiation and IP Moat
Amprius continues to emphasize its proprietary silicon-anode technology, validated by over 80 patents and third-party testing. The company’s batteries are positioned as unmatched in safety, energy density, and fast-charging capability, underpinning its traction in high-stakes aviation and defense applications.
Key Considerations
Amprius’s Q1 demonstrates commercial momentum, but also exposes the challenges of scaling an advanced battery technology business from pilot to volume production.
Key Considerations:
- Execution Risk on Scale: The transition from contract manufacturing to in-house gigafactory production is critical for margin normalization and long-term cost structure.
- Product-Market Fit Validation: Ongoing customer qualification will determine how many of the 82 engaged customers convert to meaningful volume orders.
- Capital Intensity and Dilution: Funding the Colorado facility and future R&D may require further equity issuance, impacting shareholder dilution.
- Product Mix Implications: Prioritizing Sitecore for initial volume may accelerate revenue, but premium CEMEX demand remains capacity constrained, possibly leaving value on the table.
Risks
Material risks for Amprius include ongoing negative gross margins, execution complexity in scaling manufacturing, and potential delays or cost overruns in the Colorado facility build-out. Customer qualification cycles remain unpredictable, and the shift to contract manufacturing introduces quality and supply chain dependencies. The company’s capital needs may result in further dilution if non-dilutive sources fall short, while competition in advanced battery chemistry remains intense.
