Upturn Advisory & Investor View for AMPX

10/28/2026: AMPX (1-star) is currently NOT-A-BUY. Pass it for now.

Amprius Technologies is an early-stage battery developer specializing in high-performance silicon-anode cells for the aerospace and drone sectors. Its core strength lies in its patented technology, which offers higher energy density than traditional batteries and is increasingly recognized in mission-critical applications. The primary growth opportunity involves scaling production at its Colorado facility to meet demand from the emerging electric aviation market. Risks include significant capital requirements, high operating losses, and intense competition from much larger battery manufacturers. The company is best suited for growth-oriented investors with a high risk tolerance who are willing to monitor manufacturing progress and contract wins.

Upturn Scorecard

Upturn Star Rating

★★★★★
AMPX receives a 3-star rating, supported by strong analyst coverage. The rating is constrained by weak unit economics, soft quantitative characteristics, and weak price momentum.

Company Fundamentals

★★★★★
AMPX has moderate overall fundamentals (3 stars), with soft financial health, solid growth momentum, and solid ownership. In FY2025 versus FY2024, moderate earnings growth (+1.4%) and strong revenue growth (+202.1%) are partially offset by weak cash generation (FCF margin -48.7%), weak profitability (net margin -60.3%), modest insider ownership of 1.18%.

Financial Health Rating

★★★★★
AMPX's financial health is soft, with the relatively strongest area being solid liquidity, including working-capital and asset support (WC/assets 69.2%). Profitability is weak (1 stars), which helps explain the 2-star overall score.

Growth Momentum Score

★★★★★
Revenue growth is AMPX's strongest growth driver at +202.1% FY2025 versus FY2024 (strong, 5 stars). By comparison, while earnings growth (+1.4%, moderate) and free-cash-flow growth (+2.8%, moderate) hold the profile back, so recent growth is not broad-based across the business.

Ownership

★★★★★
Institutional ownership is 69.6% and approximately 97.8% of outstanding shares are publicly tradable, supporting liquidity and institutional participation. Insider ownership of 1.18% provides only moderate management-shareholder alignment.

BlackRock Inc 7.76%
Vanguard Capital Management, LLC 3.81%
Morgan Stanley - Brokerage Accounts 3.50%
Two Sigma Investments LLC 2.96%
UBS Group AG 2.79%

Unit Economics (Per $1K Revenue)

★★★★★
AMPX generates approximately $113 of gross profit, $-639 of operating income, and $-487 of free cash flow for every $1,000 of revenue. Based on FY2025 results. Operating losses and cash burn explain the 1-star rating, with weak cash conversion and weak capital efficiency.

Economic Dimensions

★★★★★
Effective Tax Rate: 0.00%

Quantitative Style Profile

★★★★★
AMPX has a liquid profile. Weak momentum is the primary drawback, while soft valuation.
