Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview	Overview Company Background and Nature of Operations Amprius Technologies, Inc. (hereafter referred to as the “Company,” “we,” “us,” or “our”) develops, manufactures and markets lithium-ion batteries for mobility applications, including aviation, ground and marine vehicles. We have been in commercial battery production since 2018 and our disruptive silicon anode technology is intended to enable batteries with high energy density, high power density and fast charging capabilities over a wide range of operating temperatures. We are incorporated in the State of Delaware. Our corporate headquarters is located in Fremont, California. Liquidity and Capital Resources As of June 30, 2026, we had cash and cash equivalents of $74.5 million. We believe that our cash and cash equivalents will be sufficient to fund our obligations over twelve months from the date these condensed consolidated financial statements are issued. We may receive additional funds if our outstanding stock warrants are exercised for cash. During the three and six months ended June 30, 2026, we received a total of $12.3 million and $14.2 million, respectively, from the cash exercise of our stock warrants. Since our inception, we have incurred recurring losses and negative cash flows from operations. During the three and six months ended June 30, 2026, we incurred a net loss of $3.2 million and $8.2 million, respectively, and at June 30, 2026, our accumulated deficit was $226.6 million. We expect to incur additional losses in the future as we scale our business and increase our operating expenditures, including our research and development spend. We may raise additional funds in order to meet our future operating and capital expenditure requirements, and we may be unable to raise additional funds or enter into such other agreements when needed on favorable terms or at all. If sufficient funding is not raised, we may need to reduce our spending activities, which may negatively affect our ability to achieve our operating goals. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional dilution. Other Risks and Uncertainties We face risks related to political change, terrorist activity, and armed conflict such as the military conflicts between Russia and Ukraine and in the Middle East. These military conflicts have led to volatility in the global economy and have contributed to and may continue to contribute to, inflation, volatility in the credit and capital markets, and interruption in the global supply chain. Our batteries are incorporated into end products used in the defense industry by customers in jurisdictions experiencing military conflict. Any cessation or escalation of these conflicts could also impact future sales. Conversely, any cessation or de‑escalation of these conflicts could alter regional market dynamics and competitive conditions. It is difficult to accurately predict the timing, outcome, or broader impact of these developments. Furthermore, increased freight charges from our carriers has become more common and are expected to continue into the foreseeable future due to elevated oil prices as a result of geopolitical tensions in the Middle East. In addition, we face risks related to significant changes in the United States’ trade policy, such as the imposition or plan to impose significant tariffs on certain product categories imported from China and other countries. These countries have taken or may plan to take retaliatory actions, including imposing additional tariffs on their importation of a wide range of products from the United States, which could potentially lead to adverse impacts on global trade. For example, recent regulatory developments in China have introduced new export controls on certain lithium-ion batteries, the materials used in their production, and related manufacturing equipment and technologies. Enforcement of these controls has been suspended until at least November 2026, pending the outcome of further negotiations between United States and China. These measures, if they are enforced, could affect our partners and suppliers, disrupt our supply chain, increase costs, or require us to diversify our supply chain. Although these global risks did not have a significant adverse impact on us as of June 30, 2026, the extent and future outcome of such risks are highly unpredictable and uncertain and may adversely affect our future financial condition, results of operations and cash flows.
