BofA update shows where active managers are putting money
Introduction & Market Context
Ensurge Micropower ASA (ENSU) presented its latest investor update on May 15, 2025, highlighting significant progress in its solid-state microbattery technology and growing commercial pipeline. The company’s stock closed at 1.47 on May 14, up 2.37% ahead of the presentation, trading in a 52-week range of 0.77 to 1.70.
Ensurge is positioning itself in a rapidly expanding market, which it estimates at over $10 billion with a projected compound annual growth rate of 26%. This growth is primarily driven by increasing demand for smaller, more functional devices requiring specialized battery solutions across wearables, hearables, medical devices, sensors, and defense applications.
Technology Performance Highlights
The presentation emphasized Ensurge’s technological achievements, particularly in fast-charging capabilities and pulse discharge performance. The company has successfully demonstrated its microbattery technology on a 10µm substrate in 2024, with products now being shipped to evaluation partners.
As shown in the following performance graph, Ensurge’s batteries can reach 80% capacity in just 8 minutes and 90% capacity in 10.5 minutes, with full charging achieved in under 24 minutes—reportedly five times faster than competing solutions:
The company also showcased its 12.5C pulse discharge capability, which enables a 4mAh battery to drive 50mA 250μs pulses for more than 30 seconds. This feature is particularly valuable for wearable health monitoring applications that require short bursts of high power.
Commercial Pipeline and Business Strategy
Ensurge reported significant commercial traction with over 120 potential customers across multiple sectors. The company has secured 13 evaluation agreements and is focusing on converting these into volume contracts, non-recurring engineering (NRE) arrangements, joint development agreements (JDAs), and licensing deals.
The following chart illustrates Ensurge’s customer pipeline distribution across market segments:
The company’s business model encompasses three primary segments: direct battery production for bespoke applications, partnerships/outsourcing arrangements, and technology licensing. This multi-faceted approach allows Ensurge to monetize its technology across different market segments while focusing its internal manufacturing on premium applications.
Manufacturing Capabilities
Ensurge detailed its roll-to-roll (R2R) manufacturing process, which enables scalable production of its solid-state microbatteries. The company’s Silicon Valley technology center is designed to support increasing production volumes, with plans to deliver on a 150,000-unit contract by the end of 2025.
The manufacturing process begins with R2R deposition of cathode and solid electrolyte materials, followed by customization of battery dimensions and stacking of multiple unit cells to form the final microbattery product. The resulting batteries are surface-mount technology (SMT) compatible, facilitating integration into various electronic devices.
Strategic Advantages and Market Positioning
The presentation highlighted Ensurge’s key competitive advantages, including its unique solid-state battery technology, scalable manufacturing approach, and high barriers to entry created by over $350 million invested in development over 15 years.
As summarized in the following matrix, the company believes it has established significant differentiation in a fragmented competitive landscape:
Forward-Looking Statements
For 2025, Ensurge is focusing on four key priorities: packing, stacking, and cycling its 28L and 43L batteries; pursuing JDAs to fund technology development; ramping up manufacturing capacity; and delivering on its 150,000-unit contract by year-end.
The company is also advancing negotiations with Fortune 500 companies for additional JDAs, which could accelerate its technology roadmap for variable energy density (VED) and form factor innovations. Licensing is being positioned as a path for commercialization in high-volume markets.
While Ensurge’s presentation painted an optimistic picture of its technological progress and commercial prospects, investors should note that the company is still in the early stages of commercialization. The successful execution of its manufacturing scale-up and conversion of evaluation agreements into revenue-generating contracts will be critical metrics to watch in the coming quarters.
