Amprius Technologies: Does the Battery Thesis Still Work Without Scale?

Amprius Technologies (AMPX) reports second-quarter 2026 results before market open on Tuesday, August 5, 2026, with a conference call scheduled for 8:30 a.m. Eastern time. The central question: can the silicon anode battery maker sustain the momentum from its raised full-year guidance and strong Q1 performance, or will the recent earnings miss and deteriorating technical picture signal a reversal? With the stock trading at $10.81—well below its 50-day, 100-day, and 200-day moving averages—and analyst sentiment weakening, this report will test whether AMPX's growth trajectory remains intact.

Part 1: Earnings Preview

Amprius Technologies develops and manufactures high-energy density lithium-ion batteries using silicon anode technology, primarily serving aerospace, defense, and premium consumer electronics markets. The company's SiCore product line represents 97% of its revenue mix, with geographic exposure split across EMEA (58%), North America (21%), and APAC (21%).

Amprius is expected to report Q2 2026 results on August 5, 2026, before market open. The consensus estimate calls for an EPS loss of $-0.03 on revenue of approximately $29.22 million. The company most recently reported Q1 2026 EPS of $-0.04, which missed the consensus estimate of $-0.02 by 100%. Year-over-year, the Q2 estimate of $-0.03 represents 40% improvement versus the $-0.05 loss reported in Q2 2025, reflecting the company's path toward profitability.

Three key themes define this earnings story:

Revenue Acceleration and Raised Guidance: Following Q1 revenue of $28.5 million (up 153% year-over-year and 13% sequentially), management raised full-year 2026 revenue guidance to at least $130 million—a $5 million increase from prior forecasts. Investors will watch whether Q2 delivers the "reacceleration" management promised for the June quarter, and whether the company can maintain momentum toward its full-year targets.

Path to Profitability: Management has set aggressive profitability targets for 2026, including full-year adjusted EBITDA of at least $4.0 million and a net loss ceiling of no more than $8.0 million (less than $0.06 per share). With Q1 gross margin at 20% (targeting ~25% for the full year) and Q1 adjusted EBITDA at negative $1.8 million, the trajectory toward these goals will be critical to assess.

Operational Execution and Cash Management: After Q1 cash use of $37.3 million (including a ~$20 million Colorado lease settlement), cash stood at $62.4 million with no debt. With full-year OpEx expected near $50 million and CapEx under $10 million, investors will scrutinize whether the company can achieve its profitability targets while maintaining adequate liquidity without additional capital raises.

Analyst commentary ahead of the release emphasizes the company's strong revenue growth trajectory and improving gross margins, with the raised guidance providing confidence in demand visibility. However, the Q1 earnings miss—despite revenue beating estimates—has raised questions about the pace of operating leverage and whether cost controls can keep pace with growth.

Part 2: Historical Earnings Performance

Amprius has demonstrated a mixed but improving earnings track record over the past four quarters. The company beat EPS estimates in three consecutive quarters (Q2 2025 through Q4 2025) by substantial margins—37.5%, 50%, and 75% respectively—showing consistent outperformance as losses narrowed from $-0.05 to $-0.01. However, this streak ended abruptly in Q1 2026, when the company reported a loss of $-0.04 versus the $-0.02 consensus, missing by 100%.

The pattern reveals a company that was successfully executing on its path to profitability through late 2025, but hit a speed bump in the most recent quarter. The Q1 miss is particularly notable given that revenue exceeded estimates by 11%—suggesting the shortfall was driven by operational costs or margin pressure rather than top-line weakness. The year-over-year improvement trend remains intact, with losses consistently narrowing compared to prior-year periods, but the recent miss raises questions about whether the company can deliver on its aggressive profitability targets for the remainder of 2026.

Note: These figures reflect diluted GAAP earnings per share, reported before non-recurring items, and may differ from the non-GAAP figures used by some sources.

Part 2.1: Price Behavior Around Earnings

Amprius typically reports earnings before market open, meaning Day 0 represents the first full trading session where investors react to results, while Day +1 captures follow-through momentum.

AMPX exhibits highly volatile post-earnings price action, with an average absolute Day 0 move of 6.92% and Day +1 move of 17.74%—both well above typical market reactions. The most recent earnings report (May 6, 2026) exemplifies this volatility: the stock gained 3.69% on Day 0 but then plunged 27.40% on Day +1, the largest two-day swing in the dataset. This dramatic reversal followed the Q1 earnings miss and suggests investors initially focused on the revenue beat before reassessing the profitability implications.

Historically, Day +1 moves have been particularly pronounced, averaging 17.74% with a range of 22.07%, indicating that the market often takes a full session to digest results and adjust positioning. The March 2026 and November 2024 reports both saw Day +1 gains exceeding 30%, while the May 2026 report saw the 27% decline. This pattern suggests AMPX is prone to significant post-earnings momentum—in either direction—making the initial reaction less predictive of the ultimate move.

Part 2.2: Options Market Expected Move

The options market is pricing a 12.97% expected move for this earnings release, which sits between the historical Day 0 average (6.92%) and Day +1 average (17.74%). This suggests options traders are anticipating volatility closer to the stock's typical two-day combined reaction, though below the extreme 22.07% average Day +1 range seen historically.

Part 3: What Analysts Are Saying

Analysts maintain a bullish stance on AMPX despite recent weakness, with a consensus rating of 4.55 out of 5.0 (Strong Buy territory) and an average price target of $23.33—implying 116% upside from the current price of $10.81. The rating breakdown shows 9 Strong Buys, 1 Moderate Buy, and 1 Strong Sell among 11 analysts covering the stock, with price targets ranging from $18.00 to $33.00.

However, sentiment has deteriorated over the past month. The consensus rating has declined from 4.73 to 4.55, with one Hold rating shifting to a Strong Sell. This downgrade likely reflects concerns following the Q1 earnings miss and the stock's 33% decline from its 50-day moving average of $14.05. Despite the recent weakness, the analyst community remains overwhelmingly positive on the long-term story, with the $23.33 average target suggesting conviction that the company's growth trajectory and path to profitability remain intact.

The wide range between the high ($33.00) and low ($18.00) price targets—spanning 83%—reflects meaningful disagreement about execution risk and the timeline to profitability. Bulls appear focused on the raised revenue guidance and expanding addressable market in aerospace and defense, while the lone bear likely questions whether the company can achieve its aggressive profitability targets without additional capital raises.

Part 4: Technical Picture

AMPX enters earnings in a deteriorating technical position, with the Barchart Technical Opinion showing a 56% Sell signal—unchanged from last week but significantly weaker than the 24% Sell reading from a month ago. The stock is trading at $10.81, positioned above its 5-day ($9.69), 10-day ($9.66), and 20-day ($10.32) moving averages, but below all longer-term averages: the 50-day ($14.05), 100-day ($16.18), and 200-day ($13.77). This configuration indicates a recent short-term bounce within a broader downtrend.

Timeframe Analysis:

• Short-term (50% Sell): Moderate sell signal suggests near-term momentum remains negative despite the recent bounce off lows
• Medium-term (50% Sell): Moderate sell signal indicates intermediate-term trend pressure continues to weigh on the stock
• Long-term (50% Sell): Moderate sell signal reflects sustained weakness in the longer-term trend structure

Trend Characteristics: The technical environment shows Average strength but is Weakening, suggesting the stock is in a vulnerable position heading into earnings with limited technical support.

The key technical level to watch is the 50-day moving average at $14.05, which represents a 30% premium to current levels and would need to be reclaimed to signal a meaningful trend reversal. The stock's 23% decline from the 20-day moving average to current levels, followed by the recent bounce back above that average, suggests short-term oversold conditions may have been relieved. However, with all three timeframes showing 50% Sell signals and the stock still deeply below its 50-day, 100-day, and 200-day averages, the overall technical setup is cautionary heading into earnings. A strong beat and raised guidance would need to be substantial to overcome the negative momentum, while any disappointment could trigger a retest of recent lows given the lack of technical support below current levels.
