Amprius Technologies, Inc. stock jumps on $75M grant, but overbought signals flash. 28 September 2026 Amprius Technologies, Inc. stock is rallying behind a clear catalyst: a $75 million U.S. Department of War defense grant. The funding converts an existing domestic EV facility into drone battery production, giving AMPX a tangible fundamental reason to rally atop an already improving technical picture. Key takeaways. * AMPX closed at $10.85, above both the 20-day EMA ($9.89) and 50-day EMA ($10.68). * The $75 million U.S. Department of War grant will fund conversion of an EV facility into drone battery production. * Daily RSI14 at 60.24 signals firm bullish momentum without overbought extremes. * Hourly RSI14 at 77 and 15-minute RSI14 at 83.83 warn the rally is stretched in the short term. * The 200-day EMA at $12.52 remains the key medium-term ceiling yet to be challenged. Daily structure - recovery testing its ceiling. Amprius Technologies, Inc. stock has shifted from a defensive posture into an active reclaim of near-term trend control. However, the broader daily trend remains capped below the 200-day EMA at $12.52. EMA alignment and trend control. The stock closed at $10.85, comfortably above both the 20-day EMA at $9.89 and the 50-day EMA at $10.68. That alignment tells a clear story: AMPX has shifted from defense into an active reclaim of near-term trend control. Still, the 200-day EMA sits far above at $12.52, meaning the broader daily trend remains technically capped until price can close that gap. Momentum and volatility signals. Momentum on the daily timeframe backs the recovery narrative without screaming exhaustion. RSI14 reads 60.24, firmly bullish but with room before overbought territory. Meanwhile, the MACD line remains negative at -0.13 against a signal of -0.29, yet the histogram has turned positive at 0.16. That combination usually points to an early-stage bullish crossover in the making. Volatility has also expanded notably. Daily ATR14 stands at 0.56, and the close at $10.85 sits above the upper Bollinger Band at $10.48. That stretched daily candle signals a strong directional push rather than an orderly grind higher. The daily pivot at $10.88 sits essentially at the close, with resistance at $11.15 and support at $10.57 marking the next battle lines. 1H timeframe - confirmation with a warning sign. The hourly chart reinforces the bullish case while simultaneously flagging stretched conditions. Price confirms the daily uptrend, but overbought readings suggest the move has run ahead of itself. Price at $10.93 sits well above the hourly EMA stack - 20-period at $9.88, 50-period at $9.74, 200-period at $9.84 - with short-term averages bunched tightly together. That alignment is consistent with an active uptrend. That said, the 50-period and 200-period EMAs sit very close together, signaling the underlying hourly trend is still relatively young. MACD on the 1H is positive at 0.12 against a 0.06 signal, another confirming indicator for near-term strength. At the same time, the hourly RSI14 at 77 is a legitimate overbought reading. Price at $10.93 trades above the 1H upper Bollinger Band of $10.38. That reinforces that the rally has moved quickly - perhaps too quickly for this timeframe to sustain without a pause. In short, the 1H confirms the daily bullish tilt while flagging that the move is stretched and vulnerable to a short-term cooling-off period. 15-Minute execution view - overheated conditions. The 15-minute chart reads outright bullish but also extremely overbought, making it relevant primarily for entry timing rather than trend assessment. RSI14 has climbed to 83.83 - an extreme reading that typically precedes at least a short consolidation or pullback within the broader move. MACD remains positive and the EMA stack - 20 at 9.91, 50 at 9.83, 200 at 9.68 - is cleanly bullish. However, traders watching for entries should respect that a 15-minute RSI above 80 rarely holds without some retracement. A pullback toward the daily pivot at $10.88 or support near $10.57 would not be surprising. The bullish and bearish paths for Amprius Technologies, Inc. stock. The path forward for Amprius Technologies, Inc. stock hinges on whether the defense grant news can translate into a sustained medium-term trend shift rather than a short-lived spike. For the bulls, a sustained close above daily resistance at $11.15, followed by continuation toward the $12.52 200-day EMA, would confirm that the defense grant news has genuinely shifted the medium-term trend. Volume and follow-through in the days ahead will be the key tell. If the daily MACD histogram continues expanding and RSI holds above 50 on pullbacks, the reclaim of trend control gains credibility. On the other hand, the bearish risk centers on the stock's inability to hold above the 50-day EMA at $10.68 or the daily pivot support at $10.57. A rejection there would suggest the rally was primarily a news-driven spike, not a structural trend change. This risk is amplified by the hourly and 15-minute overbought readings finally unwinding. In that scenario, price could revert toward the daily Bollinger midline near $9.69, invalidating the near-term bullish thesis without necessarily threatening the broader recovery attempt. The stock would then need time to rebuild momentum before another test of resistance. Closing take. Amprius Technologies, Inc. stock presents a classic post-catalyst setup with both opportunity and near-term risk. Overall, momentum is strong on the lower timeframes. Daily structure is improving but not yet decisive. Overbought signals are stacked across the 1H and 15-minute charts. Elevated ATR readings suggest volatility will stay high in the sessions ahead. Positioning here should account for the real possibility of a pullback, even within an otherwise constructive trend. Uncertainty remains elevated until price proves it can hold above the daily pivot and eventually challenge the 200-day EMA. Faq. What is driving the rally in Amprius Technologies, Inc. stock? A $75 million defense grant from the U.S. Department of War is the primary catalyst. The funding will convert an existing domestic EV facility into drone battery production, giving AMPX a tangible fundamental reason to rally. What are the key resistance levels for AMPX? The immediate resistance sits at the daily pivot of $11.15. Beyond that, the 200-day EMA at $12.52 represents the key medium-term ceiling that must be overcome to confirm a genuine trend shift. Is Amprius Technologies, Inc. stock overbought? On the daily timeframe, RSI14 at 60.24 is not overbought. However, the 1H RSI14 at 77 and 15-minute RSI14 at 83.83 flag clearly stretched conditions that raise the risk of a short-term pullback or consolidation.

Amprius secures $75 million grant for american high-energy density battery production. Amprius Technologies ("Amprius" or the "Company") (NYSE: AMPX), a leader in high-performance batteries, has been awarded a grant of up to $75 million from the U.S. Department of War ("DoW") to retrofit an existing domestic production line from EV batteries to high-energy density cells for unmanned aerial systems. The grant was awarded through the DoW's Industrial Base Analysis and Sustainment ("IBAS") program, which funds domestic manufacturing capabilities critical to national defense. The primary objective of this award is to establish high-volume, commercially viable U.S. manufacturing for advanced battery systems that power unmanned aerial systems - Group 1, 2, and 3 drones. Amprius plans to use the funds to reconfigure an existing U.S.-based electric vehicle battery production line operated by a major South Korean manufacturer. At completion, planned for early 2028, the line is expected to have the capacity to produce 12 million Amprius cells annually. These cells are intended to meet the domestic sourcing requirements of the National Defense Authorization Act ("NDAA"). The conversion project is expected to cost approximately $100 million, including in-kind investments from Amprius and its South Korean partner. The modified line expands Amprius' existing contract manufacturing relationships and significantly increases the ability of the Company to provide NDAA-compliant pouch cells for key customers at scale. This project adds to the Company's global manufacturing network in China, South Korea, and the United States. "This DoW grant is intended to establish a primary source of domestic, NDAA-compliant battery production," said Amprius CEO Tom Stepien. "Our technology, combined with the U.S. manufacturing prowess of our South Korean manufacturing partner, positions us to accelerate adoption of standardized, high-performance pouch cells in a fast-growing market."
