Amprius Technologies (AMPX) Q2 2024: Shipments Outside U.S. Jump 271% as Global Demand Broadens

August 8, 2024 | By EarningsIQ Research

Amprius Technologies achieved a pivotal global inflection, with international shipments surging and half of Q2 revenue sourced outside the U.S. The company’s contract manufacturing model unlocked substantial capacity, while product innovation and customer diversification drove a record backlog. Management’s focus now turns to optimizing U.S. manufacturing, navigating industry volatility, and converting technical wins into commercial scale as market dynamics shift.

Summary

• Global Expansion Accelerates: International shipments and customer engagement surged, diversifying revenue mix beyond the U.S.
• Manufacturing Leverage Grows: Contract manufacturing partnerships unlocked mass capacity, supporting rapid product scaling.
• Execution Focus Intensifies: Near-term priorities shift to U.S. facility optimization, backlog conversion, and market-driven capital allocation.

Business Overview

Amprius Technologies develops, manufactures, and sells advanced silicon-anode lithium-ion batteries with industry-leading energy density and fast-charging capabilities. Its business model combines direct product sales, development services, and government grants, targeting aviation, electric vehicle (EV), micro-mobility, and industrial end-markets. Key product lines—SiMax and SiCore—address a spectrum of applications, with manufacturing delivered through both in-house and contract partner facilities.

Performance Analysis

Q2 2024 marked a decisive step change in Amprius’s commercial execution, as the company doubled quarterly revenue versus the prior year and broadened its customer base. Shipments reached 56 customers, with 24 new accounts across electric mobility verticals. Notably, international shipments soared 271% year-over-year, and for the first time, 50% of revenue was generated outside the U.S.—a clear signal of global traction. The company secured $7.6 million in new sales orders, driving a 32% sequential increase in backlog.

Despite robust topline momentum, gross margin deterioration persisted, with negative 195% gross margin reflecting ongoing scale-up costs, pre-construction expenses for the Brighton, Colorado facility, and an unfavorable revenue mix. Operating expenses rose modestly quarter-over-quarter, primarily due to increased stock-based compensation, but were down year-over-year on leaner G&A. Liquidity improved through a warrant tender offer and ATM usage, bolstering the cash position to $46.4 million and extinguishing over 60% of outstanding warrants.

• Customer Diversification Drives Volume: Shipments to new and repeat customers spanned aviation, drone, micro-mobility, and industrial applications.
• Contract Manufacturing Model Reduces CapEx: Partnerships in Asia provide over 500 MWh of capacity, supporting immediate scaling without heavy capital outlay.
• Backlog and Bookings Signal Demand Visibility: The $7.6 million in new orders and expanded backlog underpin near-term revenue outlook.

Execution risk remains elevated on the path to profitability, with management emphasizing scale, cost normalization, and backlog conversion as critical levers for the second half of 2024.

Executive Commentary

Strategic Positioning

1. Global Market Penetration

Amprius’s pivot to international markets is now material, with half of Q2 revenue sourced outside the U.S., up from a historically domestic-heavy mix. The company is targeting not only North America and Europe but also expanding into Asia, leveraging its unique battery performance to win new customers in diverse geographies.

2. Flexible Manufacturing Capacity

Contract manufacturing partnerships provide Amprius with access to over 10 million pouch cells and 125 million cylindrical cells annually, supporting rapid scaling and minimizing upfront capital requirements. This model allows the company to meet global demand, maintain quality, and preserve balance sheet flexibility as it ramps new products.

3. Product Innovation and Validation

Amprius continues to push the technical envelope, with third-party validation of its 500 Wh/kg batteries and the launch of new SKUs such as the SA11 and SA17. The company’s batteries are now the only commercial solutions meeting certain high-performance requirements, enabling it to capture niche and volume opportunities in eVTOL, drones, and micro-mobility.

4. U.S. Manufacturing Scale-Up

Fremont and Brighton, Colorado facilities remain key to Amprius’s domestic supply chain ambitions. Progress includes qualification of silicon anode fabrication tools and a targeted year-end ramp to 2 MWh capacity in Fremont. The Brighton facility’s design is 60% complete, with management signaling a cautious, market-driven approach to construction given shifting industry dynamics and government incentives.

5. Backlog Conversion and Customer Qualification

Management is focused on moving customers from technical validation to commercial orders, with qualification cycles for new products like SiCore typically running 9 to 18 months. The company’s ability to convert backlog into revenue will be a key determinant of financial trajectory in the coming quarters.

Key Considerations

This quarter’s results reveal a company at a critical inflection—balancing technical leadership, global demand, and the realities of scaling manufacturing in a volatile industry environment.

Key Considerations:

• International Revenue Mix Shift: The rapid rise in non-U.S. shipments diversifies risk and expands Amprius’s addressable market, but also introduces new regulatory and competitive considerations.
• Margin Recovery Path: Persistent negative gross margins highlight the urgency of scaling production and optimizing cost structure, particularly as pre-construction and ramp-up costs weigh on near-term results.
• Backlog Execution: The growing order book and backlog provide revenue visibility, but timely conversion from technical qualification to commercial scale remains essential for sustained growth.
• Capital Allocation Discipline: Management’s flexible approach to facility build-out and capital raising reflects prudent risk management in an industry facing demand, policy, and supply chain uncertainty.

Risks

Amprius faces material risks tied to manufacturing scale-up, prolonged negative margins, and execution delays in bringing new facilities online. Policy uncertainty, especially around U.S. government incentives and trade tariffs, could impact domestic expansion plans. The company’s contract manufacturing model reduces some capital risk but introduces dependence on third-party partners for quality and delivery. Customer qualification cycles are long and unpredictable, potentially delaying revenue realization even as backlog grows.

Forward Outlook

For Q3 2024, Amprius expects:

• Continued shipment growth, with the majority of new bookings converting in the back half of the year
• Further optimization and ramp-up of Fremont’s 2 MWh production line by year-end

For full-year 2024, management maintained a cautious but constructive outlook:

• Year-end completion of Brighton facility design, with updated cost estimates and regulatory resolution

Management highlighted several factors that will shape execution:

• Customer demand cycles and technical qualification timelines
• Industry-wide shifts in demand, supply, and government policies, especially around U.S. incentives

Takeaways

Amprius’s Q2 demonstrates commercial momentum, but the path to profitability hinges on operational discipline and market-driven capital allocation.

• Global Diversification: International traction reduces reliance on U.S. customers and positions Amprius for broader industry relevance.
• Manufacturing Flexibility: The hybrid in-house and contract model offers scalability but requires vigilant quality and supply chain management.
• Backlog Conversion: Investors should watch for evidence of backlog translating into recurring, high-volume commercial orders as a key signal of business model validation.

Conclusion

Amprius is executing on a global growth strategy, with contract manufacturing capacity and product innovation driving near-term momentum. The company’s next phase will test its ability to scale profitably, optimize U.S. operations, and manage capital in a dynamic macro environment.
