Silicon-anode battery developer reports record sales, manufacturing progress, and $621 million liquidity cushion
Enovix Corporation (ENVX) reported fourth-quarter and full-year 2025 results highlighting steady revenue growth, improving margins, and continued progress toward commercializing its advanced silicon-anode lithium-ion batteries.
Fourth-quarter revenue reached a record $11.3 million, up from $9.7 million a year ago. Full-year revenue climbed 38% to $31.8 million, driven primarily by defense and industrial shipments from its South Korea operations. Non-GAAP gross margin improved significantly to 23% for the year, reflecting operational execution gains and higher production volumes.
CEO Dr. Raj Talluri emphasized that completing smartphone qualification remains the company’s top priority. During the fourth quarter, evaluation samples met energy density, fast-charge, and safety requirements, while cycle-life performance improved toward customer-defined targets. Enovix has passed 70 of 75 qualification specifications with two smartphone partners and identified multiple pathways to clear remaining hurdles.
Chairman T.J. Rodgers noted that the Penang manufacturing line is largely functional, with the primary production constraint tied to laser dicing throughput. The company is pursuing both process optimization and alternative mechanical solutions to unlock higher volume capacity.
Beyond smartphones, Enovix sees smart eyewear as a potential early commercialization opportunity. The AI-1 battery platform appears to meet the volumetric energy density requirements of leading smart eyewear manufacturers, and initial production demand has begun as customers prepare for commercial launch.
Manufacturing readiness improved throughout 2025, including leadership consolidation under Kihong Park and enhanced advanced manufacturing expertise. Fab2 in Malaysia continues to show yield and throughput gains, positioning Enovix for higher-volume production.
Despite continued operating losses, free cash flow improved year over year. The company ended 2025 with approximately $621 million in cash and marketable securities, providing runway to complete qualification and scale production.
With industry-leading energy density of 935 Wh/L and expanding engagement across smartphones and AI-powered wearables, Enovix is positioning itself at the forefront of next-generation battery technology commercialization.
