Amprius may recognize additional charges, realize gains or losses, incur financing costs or interest expense, or experience other events in 2026, including those related to capacity expansion, supply chain disruptions, or further cost inflation, that could cause actual results to vary materially from this outlook. See Forward-Looking Statements below.

Amprius has not provided a reconciliation of the 2026 outlook for non-GAAP Adjusted EBITDA in reliance on the unreasonable efforts exception provided under Item 10(e)(1)(i)(B) of Regulation S-K due to the uncertainty regarding, and the potential variability of, reconciling items such as, the amount and timing of potential non-recurring items. The Company is unable, without unreasonable efforts, to forecast certain items required to develop meaningful comparable GAAP financial measures.

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 the non-GAAP measures: Adjusted Net Loss, Adjusted EBITDA and Adjusted EBITDA margin, which excludes from our GAAP net loss, interest, taxes, depreciation and amortization, as well as other significant expenses including stock-based compensation 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 non-cash impact of the increase in fair value related to the warrant exchange, as the exchange of warrants for common shares is not related to our ongoing operations. We exclude the operating costs for our former facility in Colorado, as these costs were recurring in the past but with the termination of the lease in January 2026, 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 reconciliations of non-GAAP net loss and non-GAAP Adjusted EBITDA to GAAP net loss, the most directly comparable GAAP financial measure.
