Company overview

Amprius Technologies, Inc. is a U.S. battery technology company headquartered in Fremont, California. The company focuses on high‑energy lithium‑ion cells that use silicon‑dominant anodes and silicon nanowire structures to increase specific energy compared with conventional graphite anodes.

Amprius aims to serve markets where energy density and weight are critical, including unmanned aerial systems (UAS/drones), aerospace, defense, electric vehicles (EVs) and other high‑performance mobility segments. The company’s branded product families—commonly referenced as SiCore and SiMaxx in company materials—are designed to offer higher cell‑level energy density than typical graphite‑anode lithium‑ion cells.

amprius stock represents ownership in the company and trades on the New York Stock Exchange under ticker AMPX.

History

Amprius was founded in 2008 to commercialize silicon nanowire anode technology originally developed in academic and research settings. The company’s early years focused on materials research, proof‑of‑concept cell assembly and small‑scale validation with strategic technology partners.

Over the 2010s, Amprius advanced its silicon anode process—moving from laboratory demonstrations to prototype cells with progressively higher specific energy. The company invested in pilot manufacturing and scale pilots to transition the technology toward production‑grade cells and modules.

Key milestones across the company’s timeline include:

• Technology maturation of silicon nanowire anodes and membranes.
• Demonstrations of cells with higher gravimetric energy density than conventional lithium‑ion cells.
• Establishment of R&D and pilot manufacturing facilities in Fremont, California.
• Commercial pilots and collaborations with aerospace and UAS integrators.
• Transition to a public company via an exchange listing under AMPX.

IPO and public listing

Amprius completed its path to a public listing and began trading on the New York Stock Exchange under the ticker AMPX. As a listed company, Amprius is subject to SEC reporting requirements and regular public disclosure of financial results, operating metrics and material events.

Investors seeking amprius stock quotes typically consult major market data providers; company investor relations materials and official SEC filings are the primary sources for corporate disclosures.

Technology and products

Amprius’s core technical differentiation is its silicon‑dominant anode technology, often implemented as silicon nanowires. Silicon has a higher theoretical capacity than graphite, which enables higher cell‑level energy density if challenges such as volumetric expansion and cycle durability can be controlled.

The company’s product families and technical attributes are often described as follows:

• SiCore: product line focused on high specific energy cells suitable for aerospace, drone and other weight‑sensitive applications.
• SiMaxx: cell and module platforms engineered for higher capacity and integration into battery packs for mobility and specialty applications.

Technical advantages claimed for silicon‑anode cells include materially higher gravimetric energy density (watt‑hours per kilogram) at the cell level. Typical cell formats can include cylindrical, prismatic and pouch cells depending on application requirements and integration constraints.

Technical caveats: silicon‑dominant anodes can pose manufacturing and cycle‑life challenges. Commercialization requires process controls, electrolyte formulation, and cell engineering to deliver acceptable life, safety and cost profiles for target markets.

Applications and customers

Prime end markets for Amprius batteries include:

• Unmanned aerial systems (UAS)/commercial and defense drones — where improved flight time and payload capacity are high value.
• Aerospace and aviation applications — including small aircraft and specialty aviation uses that require high energy density.
• High‑performance mobility and potential EV segments where weight and range are differentiators.

Company disclosures and press releases historically mention pilot programs, prototype deliveries and collaborations with UAS manufacturers and aerospace integrators. For specific customer names and contract values, investors should consult Amprius press releases and SEC filings.

Manufacturing and operations

Amprius operates R&D and pilot manufacturing facilities in Fremont, California. The company’s near‑term operational objectives include scaling manufacturing throughput, improving yields, and reducing production costs to align with commercial demand.

Scaling production of silicon‑anode cells typically involves ramping electrode fabrication, coating and cell assembly lines, and establishing supply chains for active materials and specialized components. Amprius has discussed partnerships and alliance approaches as part of its scaling strategy in corporate communications.

Operational risks for amprius stock holders include the capital intensity of scaling manufacturing and the execution risk inherent to moving from pilot to high‑volume production.

Corporate governance and management

Amprius’s executive leadership and board of directors are disclosed in SEC filings and on the company’s investor relations pages. Key elements investors often review include:

• Chief Executive Officer and other named executive officers.
• Directors and their industry experience.
• Insider ownership and equity compensation practices.

Notable leadership changes are announced via press releases and Form 8‑K filings. For the most current leadership roster and biographies, consult the company’s investor relations materials.

Financials

Public financial statements (annual Form 10‑K and quarterly Form 10‑Q filings) provide the authoritative record of Amprius’s financial performance and balance sheet position. Typical financial topics investors review when evaluating amprius stock include:

• Revenue trends and customer concentration.
• Gross margin and operating expenses related to R&D and manufacturing scale‑up.
• Net income or net loss and adjusted metrics if presented.
• Cash, cash equivalents and access to capital (including equity offerings and at‑the‑market programs).
• Capital expenditures and commitments tied to manufacturing expansion.

Because Amprius operates at the intersection of deep R&D investment and manufacturing scale‑up, the company has historically reported operating losses while investing in manufacturing capacity. Any material financing events (equity offerings, ATM programs, debt facilities) are reported in SEC filings and investor communications.

Investors should rely on the company’s Form 10‑K and the latest Form 10‑Q for quantifiable figures and detailed notes.

Risks and controversies

amprius stock, like any investment in a technology and manufacturing company, carries multiple industry and company‑specific risks. Major categories of risk include:

• Manufacturing scale‑up risk: Scaling electrode and cell production reliably at commercial volumes is capital‑intensive and operationally complex.

• Technology commercialization risk: Silicon anode technology must balance energy density with cycle life, calendar life, safety, and cost targets.

• Supply‑chain and raw material risk: Access to critical materials and components (anode/cathode precursor materials, separators, electrolytes) can impact costs and delivery schedules.

• Competition: Large battery manufacturers and emerging technologies compete for the same markets and may achieve cost or performance advantages.

• Regulatory and safety risk: Battery cells are subject to rigorous safety standards, transport rules and regulatory approvals in certain aerospace and defense applications.

• Financial and liquidity risk: Continued operation and planned manufacturing expansion may require additional capital, potentially diluting existing shareholders.

• Market and valuation volatility: Small‑cap and technology stocks often show larger price swings and lower liquidity relative to large‑cap counterparts.

If any legal, regulatory, or operational controversies are publicly reported, the company discloses material developments in its filings. Investors should review the company’s risk disclosure sections in Form 10‑K and other filings for a comprehensive enumeration of risks.
