-
Expecting 2026 revenue growth of at least 70% to $125 million or more, with net loss below $8 million, and positive non-GAAP Adjusted EBITDA of at least $4 million
Amprius Technologies, Inc. ("Amprius" or the "Company") (NYSE: AMPX), a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, today announced financial results for the fourth quarter and full year ended December 31, 2025, and discussed recent business developments.
Revenue for the fourth quarter of 2025 was $25.2 million, compared to $10.6 million in the fourth quarter of 2024. Net loss was $24.4 million, compared to a net loss of $11.4 million in the fourth quarter of 2024. Net loss per share was $0.18, compared to a net loss per share of $0.10 in the fourth quarter of 2024. Results reflect a fourth quarter 2025 charge of $22.5 million reflecting the impairment of assets linked to a facility in Colorado, discussed below, along with other one-time fixed asset write-downs. Adjusting for these one-time charges, the Company’s net loss for the fourth quarter would have been $1.9 million, or $0.01 per share.
Revenue for the full year 2025 was $73.0 million, compared to $24.2 million in 2024, an increase of 202%. Net loss for the year was $44.0 million, compared to a net loss of $44.7 million in 2024. Net loss per share for the year was $0.35, compared to a loss of $0.45 per share in 2024. Adjusting for the one-time charges in Q4 of $22.5 million, the Company’s full-year 2025 net loss would have been $21.5 million, or $0.17 cents per share.

Non-GAAP Financial Measures
To supplement our financial results presented on a basis in conformity with generally accepted accounting principles in the United States (“GAAP”), we use non-GAAP measures: Adjusted EBITDA, which excludes from our GAAP net loss, interest, taxes, depreciation and amortization, as well as other significant expenses including stock-based compensation; and Adjusted net loss, which excludes from our GAAP net loss, significant one-time items that we believe are helpful in understanding our past financial performance. Our non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP.
Management believes that these non-GAAP financial measures reflect our ongoing business in a manner that allows for meaningful comparisons and analysis of trends in its business, as it excludes expenses and gains not reflective of ongoing operating results or that may be infrequent and/or unusual in nature. We exclude the operating costs for our facility in Colorado, as these costs were recurring in the past but with our decision to terminate the lease, they are no longer indicative of our ongoing operational results. We also adjust for the effect of stock-based compensation expenses noting that such expenses will recur in future periods. Although stock-based compensation is a key incentive offered to our employees, we continue to evaluate our business performance internally excluding stock-based compensation expenses.
Management also believes that these non-GAAP financial measures provide useful information to investors in understanding and evaluating our operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies. These non-GAAP measures may not be comparable to similarly titled measures presented by other companies. In this press release, we provided a reconciliation of non-GAAP Adjusted EBITDA and Adjusted net loss to GAAP net loss, the most directly comparable GAAP financial measure.
