Opening Summary
Amprius Technologies, Inc. (AMPX) is a Fremont, California-based manufacturer of advanced lithium-ion batteries built on its proprietary Silicon Anode Platform, serving the defense, aerospace, and drone markets. Shares are currently trading at $14.88, up $2.33 (+18.57%) from Wednesday's closing price of $12.55, with intraday prices ranging from $13.25 to $15.05. The rally follows a pre-market earnings release that substantially exceeded Wall Street expectations across every key metric, igniting broad investor enthusiasm.
Earnings Beat Drives the Surge
Amprius released its Q4 and full-year 2025 financial results before the opening bell on March 5, and the numbers were unambiguously strong. Q4 revenue came in at $25.2 million — beating the consensus estimate of $22.91 million and surging 137% from $10.6 million in Q4 2024 — while the non-GAAP adjusted EPS loss of just -$0.01 handily cleared the -$0.04 estimate. The company also achieved its first-ever positive quarterly non-GAAP adjusted EBITDA of $1.8 million, a milestone that signals the business is approaching an inflection point in its operating leverage, and Q4 gross margin expanded to 24%.
Full-Year 2025 Results Confirm Rapid Scaling
For the full fiscal year 2025, Amprius posted total revenue of $73.0 million — a 202% increase from $24.2 million in fiscal 2024 — reflecting explosive commercial adoption of its silicon-anode battery technology across the defense and drone supply chain. The GAAP net loss was $44.0 million for the year, but that figure included a one-time $22.5 million impairment charge related to a Colorado facility; stripping that out, the adjusted net loss was $21.5 million, or -$0.17 per share. The company ended the period with $91.9 million in cash and equivalents, providing a well-capitalized balance sheet to fund continued growth.
Bullish 2026 Guidance Amplifies Market Reaction
Management's forward outlook added further fuel to the price rally. Amprius guided for 2026 revenue of at least $125 million, representing year-over-year growth in excess of 70%, alongside positive adjusted EBITDA of at least $4 million. CEO Tom Stepien highlighted that the company expanded its customer base to over 550 customers in 2025 while tripling revenue, and pointed to deepening domestic manufacturing partnerships — including with Nanotech Energy — as key enablers of that trajectory. The guidance also benefited from the company's recently completed at-the-market equity offering, which raised approximately $97.5 million in net proceeds, giving Amprius the financial runway to scale without near-term dilution risk.
Market Context and Trading Activity
Volume tells the conviction story clearly: more than 10.9 million shares changed hands by mid-session, approximately 47% above the average daily volume of 7.4 million shares, indicating broad institutional and retail participation in the earnings-driven move. The stock opened at $13.47 and pushed as high as $15.05 intraday, breaking above both its 50-day moving average of $10.55 and its 200-day moving average of $8.96 — a technically significant development. The rally is particularly notable given that broader equity markets are facing macro-driven headwinds on the session, making AMPX's outperformance sharply divergent from the index trend. The stock's beta of 3.02 is well-suited to amplify positive earnings surprises of this magnitude.

What Comes Next for AMPX
Amprius's next earnings report is scheduled for May 7, 2026, when investors will look for confirmation that the company is tracking toward its $125 million revenue target and sustaining positive adjusted EBITDA. The company has also announced an active March 2026 investor conference schedule — including the Cantor Global Technology Conference — where management is expected to reinforce its commercial roadmap and detail the competitive advantages of its silicon anode platform. Analysts carry a consensus "Strong Buy" rating with an average price target of $15.29, a figure that today's price action is rapidly approaching, which could prompt fresh target price upgrades in the sessions ahead. Key risks remain: execution on domestic manufacturing scale-up, continued GAAP net losses as the company invests heavily for growth, and potential volatility tied to defense procurement budgets and drone market dynamics.
