Amprius Technologies ($AMPX) Q4 2025 Earnings Breakdown
A Silent Leader In Drone Batteries
Amprius Technologies AMPX 0.00%↑ just delivered one of the most important quarters in the company’s history. The Q4 2025 earnings report confirmed that Amprius is transitioning from a technology validation small cap into a scaling battery manufacturer, with demand accelerating across drones, aerospace, and defense applications. We also know there is heightened interest for their product in the domestic space at the height of American drone infrastructure ramp-up. With record revenue, improving margins, and strong 2026 guidance, the company appears to be entering a hypergrowth commercialization phase that investors may be able to benefit from.
Q4 2025 Financial Results
Amprius reported record quarterly results by beating both revenue and EPS expectations. Revenue came in at $25 million, highlighting staggering YoY growth of +137% and QoQ growth of +18%. Revenue also beat consensus expectations by roughly $2.3M, highlighting accelerating demand for the company’s battery technology. EPS came in with a surprise beat as well. The quarter also marked an operational milestone with Amprius achieving its first positive quarterly adjusted EBITDA, showcasing the early benefits of scaling production.
Full Year 2025 Performance
The broader story for Amprius in 2025 was hypergrowth. Gross annual revenue came in at $73 million, showcasing a +202% YoY change with over a third of that coming in the 4th quarter. I believe the exponential growth showcases the fact the company is trending in the right direction for an explosive 2026 with new production avenues and partnerships adding a compounding effect. The company did report a GAAP net loss of $24.4 million in Q4, largely driven by a $22.5M impairment charge from the closure of a Colorado facility which distorts the underlying profitability trend but is not concerning in the broader thesis. Excluding one-time items, operating performance improved significantly as the company began benefiting from scale.
2026 Guidance
Management issued very strong forward guidance, reinforcing the bull case. They expect 2026 revenue of at least $125 million and adjusted positive EBITDA of $4 million. On the flip side, net loss is expected to be around $8 million. This implies roughly 70% revenue growth in 2026 and continued progress toward profitability. Management also highlighted that the company is now pursuing a capital-light manufacturing model, leveraging industry partners and government incentives to scale production more efficiently leading to potential stock appreciation.
Manufacturing Expansion
The most important question to ask when looking into continued revenue expansion is: can AMPX 0.00%↑ scale production? The company is now taking several steps to address that challenge. In the last few months ther’’s been several key developments on this topic. The first being a new U.S. manufacturing partner in Nanotech Energy. This partnership opens doors for easier runways in the NDAA regulated component procurement space for U.S. entities seeking powerful Amprius batteries in drone and defense technology.
They’ve also expanded production partners in South Korea - bringing their total partnerships there to 3. This has culminated in the achievement of production getting underway overseas back in September 2025. The global manufacturing network this created allows Amprius to scale production while avoiding heavy capital expenditures. On top of that it helps create that NDAA-compliant battery supply chain I mentioned earlier, paving the way for increased probability of securing large defense and government contracts.
Technology Advantage: Silicon Anode Batteries
Amprius differentiates itself through its silicon anode lithium-ion battery technology. Compared to conventional lithium-ion batteries, silicon anode cells deliver higher energy density, higher capacity, and longer flight endurance for drones and aircraft. These batteries are already among the highest energy density, commercially available cells enabling applications where weight and endurance are critical. Key use cases include: military drones, high-altitude UAVs, electric aviation, satellite systems, and robotics/autonomous platforms. This is being reinforced through the fact some competitors in the drone dominance gauntlet are using their batteries in their systems already. Exciting stuff!
Major Tailwinds
Drone Warfare & UAV Growth
Battery performance is one of the most important constraints for drones. Batteries like Amprius’s provide higher energy density directly increases flight time, range, and payload security. As defense spending shifts toward unmanned systems, high-performance battery suppliers become critical infrastructure. AMPX 0.00%↑ stands to gain immensely as the industry is looking to grow with analysts expecting a 10x increase on drone spending over the next 10 years.
Electric Aviation
More so than drones, electric aircraft require extremely high energy density batteries. Amprius’s technology roadmap is targeting energy densities that could enable practical electric aviation platforms, an area attracting massive investment. If you follow Hidden Gems closely, you’ll know that EVTOL is also on the horizon with these vehicles requiring a massive amount of high quality power - another untapped potential market for AMPX 0.00%↑.
Defense Supply Chain Localization
Due to international security concerns the U.S. government is pushing for NDAA-compliant supply chains for critical technologies such as batteries. Companies capable of producing domestically compliant components could see significant demand from defense programs. We know UMAC 0.00%↑ is headed into this space but the market has plenty of room before saturation occurs. Amprius could fill a large portion of this gap and potentially partner with one of our favorite picks if they continue to show promise.
Aerospace and Space
Amprius batteries are already used in applications like satellites and aerospace platforms. These industries value performance over cost, which plays directly into Amprius’s strengths and gives them the opportunity for a few, huge revenue generating long-term projects.
Balance Sheet
The balance sheet is strong. Amprius ended 2025 with ~$90.5 million in cash and no debt. This gives the company a runway to continue scaling production while investing in new manufacturing capacity. As margins increase, contracts inflow, and production ramps I expect more and more cash to be added to the balance sheet in the long-term. In the short term cash will be a high-demand asset leveraged along with protentional share offerings though the former would be preferable to investors. Expect some volatility in this regard where stock price is concerned.
The Big Picture
Amprius is moving from a high-risk small cap to a quality, commercial battery supplier. The Q4 earnings report showed a handful of major green flags: triple-digit revenue growth, improving margins, positive EBITDA, and aggressive 2026 growth guidance. If management executes on manufacturing expansion and demand continues growing across drones, aerospace, and defense, Amprius could become one of the key battery suppliers powering the next generation of unmanned and autonomous systems. In a world where battery performance directly determines mission capability, Amprius is positioning itself as a critical picks-and-shovels provider in the electrification and autonomy revolution, making it a perfect fit for the Gem Vault. I think a healthy pullback is in order but I plan to increase my holdings when we dip closer to $15.
