Research Idea
Research content for general circulation. Not individualized advice. Methodology & Disclosures
Conditional growth+momentum idea: Q4 2025 revenue more than doubled YoY ($25.2M vs $10.6M) with a ~$53M order backlog and new wins (CES award, Nanotech Energy partnership, Korea Battery Alliance). Cash of ~$70â90M and no debt fund the ramp. Shares are up ~45% in 21 days and ~50% above the 21âday SMA; follow-through on backlog conversion or additional design-win news could extend the surge in the very near term.

Valuation Metrics
Fundamental Analysis
Key Financial Insights: ⢠Strong liquidity ⢠Persistent losses ⢠Negative FCF AMPX has ample liquidity and low leverage but remains undermined by persistent operating losses, negative EBITDA and FCF, and an excessively high valuation.
Price Behavior
Key Price Behavior Insights: ⢠Below short-term MA ⢠~17% pullback ⢠Midâ$14s support Support Level: $14.00â$15.00 Resistance Level: $19.30 (peak) / $18.50â$19.00 (confirmation area) Over the last month AMPX rose from $14.89 to $16.00 but is trading below the short-term moving average after a midâMarch peak near $19.30 and a ~17% pullback, so $14.00â$15.00 is key support while a move above the midâ$18sâ$19 area would confirm renewed bullish momentum.
Sentiment & News
Key News Insights: ⢠SiCore $21M ⢠Analyst upgrades ⢠Insider share-selling Amprius gained commercial traction and market recognition in late March 2026âhighlighted by a $21M SiCore cell order and TIME green-tech nodâwhile earnings-powered analyst upgrades and heavy volume pushed shares to 52-week highs even as insider sales applied short-term selling pressure.
AI Summary
Amprius has moved from a R&D story to demonstrated commercializationâaccelerating revenue, large OEM orders, and initial EBITDA improvementâbut the investment now hinges on flawless execution of scale (NDAA/domestic quals, CM reliability) and margin conversion without further dilutive capital. Monitor sequential gross-margin and adjusted-EBITDA trends, conversion of the $21M+ backlog into repeatable shipments, and quarterly free-cash-flow/dilution cadence as the make-or-break signals.
