Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	ORGANIZATION Business Combination Amprius Technologies, Inc. (f/k/a Kensington Capital Acquisition Corp. IV, a Cayman Islands exempted company incorporated with limited liability) (the “Company” or “Amprius”) was initially incorporated as a Cayman Islands exempted company on March 19, 2021. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. On September 14, 2022 (the “Closing Date”), the Company completed a business combination pursuant to the Business Combination Agreement, dated May 11, 2022 (the “Business Combination Agreement”), by and among the Company, Kensington Capital Merger Sub Corp., a wholly owned subsidiary of the Company (“Merger Sub”), and Amprius Technologies Operating, Inc. (f/k/a Amprius Technologies, Inc., a Delaware corporation) (“Legacy Amprius”). Pursuant to the terms of the Business Combination Agreement, the Company changed its jurisdiction of incorporation by domesticating as a corporation incorporated under the laws of the State of Delaware (the “Domestication”), upon which the Company changed its name to “Amprius Technologies, Inc.,” and a business combination between the Company and Legacy Amprius was effected through the merger of Merger Sub with and into Legacy Amprius, with Legacy Amprius surviving as a wholly owned subsidiary of Amprius (together with the Domestication and the other transactions contemplated by the Business Combination Agreement, the “Business Combination”). The Business Combination was treated as a reverse recapitalization. Legacy Amprius was determined as the accounting acquirer and Kensington as the accounting acquiree for financial reporting purposes based on evaluation of the following facts and circumstances: •the stockholders of Legacy Amprius owned a majority of the shares of the Company following the Business Combination; •the board of directors of the Company following the Business Combination was comprised of all of the board members of Legacy Amprius; •the senior management of the Company following the Business Combination was the senior management of Legacy Amprius; and •Legacy Amprius is larger than Kensington in terms of existing operations and number of employees. Unless the context otherwise provides, the “Company” and “Amprius” refer (i) prior to the Closing Date, to Legacy Amprius and (ii) after the Closing Date, to Amprius Technologies, Inc. and its subsidiaries, including Legacy Amprius. Kensington Capital Acquisition Corp. IV prior to the Business Combination is referred to herein as “Kensington.” Please see Notes 2 and Note 3 below for further details. Nature of Operations Amprius has developed, and since 2018, been in commercial production of lithium-ion batteries for mobility applications leveraging a disruptive silicon nanowire anode. The Company’s silicon nanowire 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. Amprius’ sole location and headquarters is in Fremont, California. The Company previously had an intercompany agreement with Amprius, Inc. (“Amprius Holdings”) to license intellectual property rights to continue to develop silicon nanowire technology. Under this agreement, Amprius Holdings provided resources and rights to use its assets to the Company, such as rights to the use of intellectual property, cash, equipment, manufacturing and office facilities, personnel, and management oversight. Amprius Holdings assigned or contributed those assets to the Company beginning in 2020 and effective May 2022, the operating assets are owned by the Company and the Company treated them as contributions from Amprius Holdings. The intercompany agreement with Amprius Holdings was terminated effective May 2022. Liquidity and Capital Resources The Company has an accumulated deficit of $86,831 as of September 30, 2022, which represents the carved-out portion of costs incurred by the Company from the inception of Amprius Holdings. Since inception, the Company has incurred recurring operating losses and cash flow deficits from operations. For the three and nine months ended September 30, 2022, the Company incurred a net loss of $4,244 and $11,276, respectively. The Company expects to incur additional losses and increased expenditures in future periods, including those associated with the design and build out of a manufacturing facility, continued research and development efforts and increased employee headcount. As of September 30, 2022, we had $73,803 of cash and cash equivalents, which includes the $70,938 net proceeds from the consummation of the Business Combination. On September 27, 2022, the Company entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) with B. Riley Principal Capital II, LLC (“BRPC II”), pursuant to which the Company has the option to sell up to $200,000 of its common stock over a 24-month period from the date of initial satisfaction of the conditions to BRPC II’s purchase obligation set forth in the Purchase Agreement, subject to certain contractual terms (the “Committed Equity Financing”). However, there can be no assurance that the Company will be able to raise $200,000 over the 24-month period as the Committed Equity Financing contains certain limitations and conditions. In addition, effective October 19, 2022, the U.S. Department of Energy’s (“DOE”) Office of Manufacturing and Energy Supply Chains (“MESC”) awarded us a $50,000 grant. This cost sharing grant is dependent on the successful negotiation of a final contract, and among the terms to be finalized are the portion of relevant costs that may be covered by the grant. There can be no assurance that negotiation of the final contract will be successful. The Company believes its current cash and cash equivalents will be sufficient to fund its operations for at least the next 12 months from the date these financial statements are issued. If sufficient capital is not raised, the Company may need to reduce its spending on building the manufacturing facility, as well as research and development and other operations, and this may negatively affect its ability to achieve corporate growth goals. Other Risk and Uncertainties The global spread of the COVID-19 pandemic has caused business disruption affecting production and sales across a range of industries. In response, the U.S. Government enacted the CARES Act, which included significant provisions to provide relief and assistance to affected organizations. While the disruption is currently expected to be temporary, there is considerable uncertainty around potential future closings, shelter in place orders, containment of the recent COVID-19 variants, and the ultimate impact of the CARES Act and other government initiatives. The COVID-19 pandemic and its resulting economic and other effects could result in significant adverse effects on the Company’s customers’ cash flow and their ability to manufacture, distribute, and sell products. This in turn may cause customers to be less able to pay invoices for customization design service or the purchase of finished batteries or may result in a reduction in the revenue from customization design service or sales of finished battery that the Company earns which are often dependent on the demand from the customer for the scope of the customized service or number of units to be purchased. This reduction could cause adverse effects on the business, results of operations, financial condition, cash flows and ability to raise operating capital. To date, this matter has not had a significant adverse impact on the Company. However, the financial impact and duration cannot be reasonably determined. Additionally, the U.S. and global markets are experiencing volatility and disruption following the geopolitical tensions and military conflict between Russia and Ukraine. The ongoing military conflict is highly unpredictable and has impacted commodity prices, volatility in credit and capital markets, and supply chain interruptions. The Company continues to monitor the situation and assess its potential impact on its business. This geopolitical conflict has led to sanctions and other penalties being levied by the United States, the European Union and other countries against Russia. Such sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets, potentially making it more difficult for the Company to obtain additional funds. Although the Company has not been adversely impacted by this ongoing military conflict to date, it is impossible to predict the extent to which its operations, or those of its customers’ suppliers and manufacturers, will be impacted in the short and long term, or the ways in which the conflict may impact its business.
