Amprius Faces 2028 Pentagon Deadline With China-Tied Supply Chain

Amprius Technologies (AMPX) carries a 'Hold' rating for the next 12 to 18 months, because robust demand for drone batteries sits alongside supply chain and compliance risks that the market has not fully priced. The company's expansion is being driven by U.S. military drones. Its supply chain, however, remains partially based in China.

The central problem is timing. The Pentagon's sourcing restriction deadline arrives in 2028, just as Amprius's U.S.-based solution is expected to come online. That leaves a narrow window between regulatory compliance and manufacturing readiness. Investors are being asked to fund the gap.

What does the 2028 deadline actually require?

The Pentagon restriction effectively bars batteries with Chinese supply chain content from U.S. defense platforms. For Amprius, a supplier whose growth is tied to American military drones, this is not an abstract policy question. It is a customer requirement with a fixed date.

Amprius must move production inputs away from Chinese suppliers before 2028. The company has not yet fully done so. Until it does, the very demand driving its expansion carries a compliance risk attached to it. Growth and exposure, in this case, are the same fact.

Why do the shares already carry the risk?

According to the analysis behind the rating, AMPX shares already price in successful U.S. manufacturing compliance. That is an optimistic assumption baked into the current valuation. Two outcomes could pressure the stock:

• Delays in bringing Pentagon-compliant production online before the 2028 deadline.
• A capital raise executed before compliant production is secured, diluting shareholders at the worst possible moment.

Either event would force the market to reprice an assumption it currently treats as settled. The stock, in short, is trading on a promise with a regulatory expiration date.

Which catalysts decide the outcome?

The analysis identifies three events that will determine whether Amprius can meet Pentagon requirements. Each one is critical.

• CAMINUS production start. The launch of the CAMINUS production line is the company's path to U.S.-based manufacturing capacity. Its schedule relative to 2028 is the decisive variable.
• China export controls. Beijing's restrictions on battery materials and components could tighten faster than Amprius can replace Chinese suppliers, converting a gradual transition into an abrupt supply shock.
• Securing non-Chinese suppliers. Qualified alternative suppliers must be in place for the full input chain, not merely for headline components. Partial qualification does not satisfy a sourcing ban.

None of these catalysts is optional. The Pentagon deadline converts all three into a single, connected requirement.

What is the investment verdict?

The rating logic is straightforward. Drone battery demand is real and growing, and Amprius sits squarely in front of it. But a company whose defense customers demand non-Chinese supply, while its own chain remains partially Chinese, carries a risk that ordinary demand analysis does not capture.

For Amprius, the next 12 to 18 months reduce to one question: whether CAMINUS and non-Chinese suppliers arrive before the Pentagon's clock runs out in 2028. The shares already assume they will.
