Amprius Technologies (AMPX) Shares Soar 2.62% to $11.80 Intraday High on Analyst Upgrades, $35M UAS Contract

Amprius Technologies (AMPX) shares surged 2.62% on September 19, 2025, extending their five-day winning streak with a cumulative gain of 44.77%. The stock reached an intraday high of $11.80, marking its highest level since September 2025, driven by analyst optimism, strategic contracts, and institutional backing.

Recent analyst upgrades have bolstered investor confidence. B. Riley, Cantor Fitzgerald, and HC Wainwright raised price targets to $11.00–$18.00, reflecting growing enthusiasm for Amprius’ silicon-based battery technology and its applications in unmanned aerial systems. The company’s Q2 2025 earnings report further reinforced this momentum, with revenue of $15.07 million exceeding expectations and cash flow improving by $5.77 million, despite ongoing losses.

Amprius secured a $35 million contract with a leading UAS manufacturer, doubling its previous order, and partnered with Nordic Wing to integrate its SiCore® cells into drones. These agreements highlight demand for its high-energy-density solutions in aviation and high-altitude platforms. Institutional investors, including Ameritas Investment Partners and Rhumbline Advisers, have significantly increased stakes, signaling long-term growth potential.

Insider sales by CEO Kang Sun and CTO Constantin Ionel Stefan raised minor concerns, though insiders retain 12.90% ownership, aligning with management’s vision. The stock’s high volatility (beta of 2.72) and unprofitability remain risks, but its niche in next-generation battery tech and expanding market visibility through industry events like the CUAV Expo position it for sustained innovation. Investors are advised to monitor upcoming earnings and contract developments as key indicators of progress.
