Amprius Technologies has reported a significant operational breakthrough, achieving a positive adjusted EBITDA for the first time in a single quarter. This milestone caps a fiscal year 2025 characterized by dramatic revenue growth and a strategic pivot that sets the stage for the coming year.
Financial Performance: A Year of Dramatic Improvement
The company’s full-year revenue surged by 202% to reach $73 million. The fourth quarter was particularly strong, with sales climbing 137% year-over-year to $25.2 million. A key indicator of operational health, the gross margin, swung decisively from negative 21% in the prior year to a positive 24%.
On an adjusted basis, EBITDA for Q4 2025 was $1.8 million, a substantial improvement from a loss of $4.8 million in the same period last year. The reported net loss of $24.4 million for the quarter is primarily attributed to a one-time, non-cash impairment charge of $22.5 million related to the closure of its Colorado facility. Excluding this special item, the adjusted net loss was $1.9 million, or $0.01 per share. The company ended the year with a solid cash position of $91.9 million.

Strategic Growth and Defense Sector Expansion
Operationally, Amprius has expanded its customer base to over 550. Strategic developments include new contracts with Nokia Drone Networks and a $2.8 million increase to an existing agreement with the Defense Innovation Unit (DIU), bringing its total value to $14.8 million. A collaboration with a U.S.-based manufacturing partner to produce NDAA-compliant battery cells marks a direct move to capture business from the U.S. defense sector.
Guidance for Fiscal 2026
Looking ahead, management has provided an optimistic outlook for fiscal 2026. The company forecasts revenue of at least $125 million, representing growth of approximately 70%. Adjusted EBITDA is projected to rise to a minimum of $4 million, while the net loss for the full year is expected to be contained below $8 million. The strategic focus will remain on scaling production capacity for high-energy-density battery solutions targeting the aviation and drone industries.
