Amprius signs up to $75 million U.S. Government battery production agreement
Amprius Technologies entered an Other Transaction Agreement with the U.S. Government on September 23, 2026, for Project acCELLerate, a domestic manufacturing effort for silicon-anode battery cells used in small unmanned aerial systems. The fixed-price award is worth up to $75 million, with payments tied to accepted milestones, and the U.S. Government has obligated about $22 million so far. Because most of the award is unfunded and subject to future appropriations, and either party can terminate for convenience on 30 days' notice, shareholders face timing and funding uncertainty.
Key points
- Agreement signed September 23, 2026, with total award value up to $75 million and no required company cost share
- About $22 million obligated to fund the base period from September 23, 2026 through September 22, 2028
- A majority of the total award remains unfunded and depends on future appropriations and milestone acceptance
- Either party may terminate for convenience with at least 30 calendar days' written notice
