Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Organization	Nature of Operations and Organization 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 higher energy density, higher power density and fast charging capabilities over a wide range of operating temperatures. Our headquarters is located in Fremont, California. Liquidity and Capital Resources As of September 30, 2024, we had cash and cash equivalents of $35.0 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. In addition, we may receive additional funds from the issuance and sale of our shares of our common stock under the At Market Issuance Sales Agreement (the “Sales Agreement”), which we entered into with B. Riley Securities, Inc., Cantor Fitzgerald & Co. and H.C. Wainwright & Co., LLC, as sales agents (the “Sales Agents”) on October 2, 2023. Under the Sales Agreement, we may offer and sell, from time to time, shares of our common stock for an aggregate offering price of not more than $100.0 million. During the nine months ended September 30, 2024 and from the date of the Sales Agreement through September 30, 2024, we sold shares of our common stock under the Sales Agreement resulting in aggregate net proceeds of approximately $10.9 million and $11.2 million, respectively. We may also receive additional funds if our stock warrants are exercised for cash. During the nine months ended September 30, 2024, we received a total of $13.6 million, after deducting stock issuance costs, from the cash exercise of our stock warrants at a temporarily reduced exercise price of $1.10 per warrant. Since our inception, we have incurred recurring losses and negative cash flows from operations. During the three and nine months ended September 30, 2024, we incurred a net loss of $10.9 million and $33.3 million, respectively, and at September 30, 2024, our accumulated deficit was $162.9 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 expect 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 Risks and Uncertainties We face risks related to abrupt 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. Although these military conflicts did not have an adverse impact on us to-date, the future outcome of such conflicts is highly unpredictable and uncertain and may adversely affect our future financial condition, results of operations and cash flows. The COVID-19 pandemic was unprecedented and resulted in significant national and global economic disruption. The extent to which public health emergencies such as the COVID-19 pandemic may impact our business, financial condition, prospects and results of operations is highly uncertain and cannot be predicted.
