Amprius (AMPX) Q1 2026 Earnings Transcript

Amprius Technologies reported Q1 revenue of $28.5 million, up 153% year over year and 13% sequentially, and raised 2026 revenue guidance to at least $130 million from $125 million. The company secured meaningful new contracts, including a $21 million Chinese light EV order and an expanded $18.1 million DIU agreement, while also announcing an exchange of more than 7 million public warrants that management says reduces future dilution by at least $70 million. Gross margin slipped to 20% from 24% due to SiMaxx overhead, but management still expects at least $4 million of adjusted EBITDA and sub-$10 million capex for 2026.

Analysis

AMPX is transitioning from a story stock to a supply-chain option on defense spending, and the market is likely underappreciating how much of the near-term upside is driven by customer program adoption rather than company-level execution. The key second-order effect is that once a platform designer standardizes around AMPX cells, battery content becomes sticky across multiple aircraft revisions and fielded fleets, which means revenue can compound faster than unit shipments as programs scale. AVAV is an indirect beneficiary because higher-endurance batteries expand mission radius and payload economics, while the broader defense UAS ecosystem gets a clearer domestic sourcing path.

The margin setup is more interesting than the headline dip suggests: the current gross margin drag is mostly a last-mile logistics and legacy-platform absorption problem, not a demand problem. If management can shift even 300-400 bps of freight/fulfillment inefficiency out of cost of goods over the next 2 quarters, the company can approach its 25% target without needing a dramatic change in product mix. That matters because the revenue ramp appears to be pulling forward into H2, so operating leverage could show up abruptly once the fixed-cost drag from SiMaxx fully clears.

The warrant exchange is the most important capital-structure event here. Removing a large overhang should mechanically reduce hedge pressure and may force short cover in a name where borrow was likely being used as a delta-neutral hedge against warrants, not a pure directional bearish bet. The market may be missing that dilution relief and improved float composition can create a self-reinforcing rerating if the company also prints another quarter of sequential growth.

The main risk is timing mismatch: defense wins and customer design-ins are real, but procurement conversion can slip by 1-2 quarters, and the new China EV order adds geopolitical and channel-concentration risk. If gross margin fails to improve in Q2/Q3, investors will start treating the 25% target as aspirational rather than executable, and the stock could de-rate even while revenue rises. The setup remains bullish, but execution needs to translate into cleaner unit economics before the market fully pays for the growth.

Key Decisions for Investors

• Go long AMPX on pullbacks over the next 1-2 weeks; target a 3-6 month trade into H2 defense procurement conversions and warrant-overhang removal. Risk/reward favors the long if sequential revenue stays positive and borrow tightens.
• Pair trade: long AMPX / short a basket of lower-quality battery hardware names with weaker defense exposure for 2-3 months. AMPX has identifiable contract pull-through, while peers with more consumer exposure are more vulnerable to margin compression.
• Buy near-dated AMPX call spreads for the next 60-90 days to express the float/dilution catalyst without paying full volatility. Best structure is a moderate upside spread to capture a rerating if shorts cover post-exchange.
• Stay long AVAV as a second-order beneficiary over the next 1-2 quarters; AMPX-driven endurance improvements should support platform economics and customer demand. Use AMPX momentum as a read-through for AVAV multiple support.
• Do not chase after a sharp post-earnings gap; wait for either a margin-confirmation print or a consolidation back toward prior support. The trade fails if Q2 gross margin remains stuck near 20%-22% ex-legacy drag.
