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 the aviation, electric vehicle (“EV”) and light electric vehicle (“LEV”) industries. 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. On October 23, 2024, our former majority stockholder and parent company, Amprius Inc. (“Amprius Holdings”), which owned an aggregate of 65.2 million shares, or 58.6%, of our common stock at that time, voluntarily liquidated and dissolved. As a result of such liquidation and dissolution, Amprius Holdings distributed, on a pro rata basis, an aggregate of approximately 57.2 million shares of our common stock to its stockholders, which include some of our executive officers and directors, and we assumed all of Amprius Holdings’ outstanding options to purchase shares of Amprius Holdings’ Class A common stock in exchange for, among other things, Amprius Holdings contributing to us a total of 5.5 million shares of our common stock that it owned, which were immediately cancelled and returned to our authorized but unissued share capital. Liquidity and Capital Resources As of December 31, 2025, we had cash and cash equivalents of $90.5 million. We believe that our cash and cash equivalents will be sufficient to fund our obligations over twelve months from the date these consolidated financial statements are issued. We may receive funds from the issuance and sale of our shares of our common stock or if our stock warrants are exercised for cash. During the year ended December 31, 2025, we sold shares of our common stock under the Sales Agreement resulting in aggregate gross proceeds of approximately $65.3 million, offset by related commissions and transaction fees of approximately $1.7 million, and received a total of $2.3 million from the cash exercise of our stock warrants. Since our inception, we have incurred recurring losses and negative cash flows from operations. During the year ended December 31, 2025, we incurred a net loss of $44.0 million and at December 31, 2025, our accumulated deficit was $218.4 million. We expect to incur additional losses in the future as we scale our business and increase our operating expenditures, such as increasing our headcount. We may need to 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 Risk 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 may 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. 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. Although these global risks did not have an adverse impact on us as of December 31, 2025, 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.
