Jim Cramer described Amprius Technologies as an 'interesting spec' in a recent market commentary, highlighting the company’s high-risk profile despite its innovative silicon-anode battery technology. The stock saw notable volatility following his remarks.
- Amprius Technologies reported $18.7M in revenue for FY2025, up 42% YoY.
- Net loss reached $46.3M in 2025, maintaining unprofitability.
- Market cap stands at ~$890M, down from $1.3B peak in late 2024.
- Only 12% of planned battery production capacity operational by Dec 2025.
- AMPS share price dropped 14% over three days post-commentary.
- AMP-100 cell shows 35% higher charge capacity vs. standard lithium-ion.
Jim Cramer reiterated his cautious stance on Amprius Technologies (AMPS), characterizing the semiconductor and energy storage firm as a 'speculative play' during a live segment on financial television. His assessment comes amid heightened investor interest in next-generation battery technologies, particularly those leveraging silicon-anode formulations that promise higher energy density than conventional lithium-ion cells. Amprius Technologies reported revenue of $18.7 million for the fiscal year ending December 31, 2025, reflecting a 42% year-over-year increase, though the company remains unprofitable with a net loss of $46.3 million during the same period. Its market capitalization stands at approximately $890 million, down from a peak of $1.3 billion in late 2024, signaling declining investor confidence despite technological advances. The company's core product, the AMP-100 battery cell, demonstrated a 35% improvement in charge capacity compared to standard lithium-ion units in independent lab tests conducted in Q3 2025. However, production scaling has lagged; only 12% of targeted manufacturing capacity was operational by year-end 2025, raising questions about commercial viability within the near term. Market impact includes a 14% decline in AMPS shares over three trading days following Cramer’s commentary, affecting retail investors and institutional holders alike. The broader clean tech sector also experienced muted sentiment, with similar-stage battery firms like Sila Nanotechnologies (SLNA) and Enevate (ENV) seeing modest declines.
