Accounting Policies [Abstract] | |
Organization and Summary of Significant Accounting Policies | 1. Organization and Summary of Significant Accounting Policies Organization Ambarella, Inc. (the Company) was incorporated in the Cayman Islands on January 15, 2004. The Company is a leading developer of low-power semiconductor solutions offering high-definition (HD) and Ultra HD compression, advanced image signal processing, and powerful artificial intelligence (AI) processing. The Company combines its processor design capabilities with its expertise in video and image processing, algorithms and software to provide a technology platform that is designed to be easily scalable across multiple applications and enable rapid and efficient product development. The Company’s system-on-a-chip, or SoC, designs fully integrate high-definition video processing, image processing, AI computer vision algorithms, audio processing and system functions onto a single chip. These low power SoCs deliver exceptional video and image quality and can extract valuable data from high-resolution video and radar streams. The Company is currently addressing a broad range of human and computer vision applications, including video security, advanced driver assistance systems (ADAS), electronic mirrors, drive recorders, driver/cabin monitoring systems, autonomous driving, and industrial and robotic applications. The Company sells its solutions to leading original equipment manufacturers, or OEMs, who include the Company’s SoCs in their products, and original design manufacturers, or ODMs, who include the Company’s SoCs in the products that they supply to OEMs, globally. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by the Company in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and, therefore, do not include all information and notes normally provided in audited financial statements. The accounting policies are described in the “Notes to Consolidated Financial Statements” in the Annual Report on Form 10-K for the 2024 fiscal year filed with the SEC on March 29, 2024 (the Form 10-K) and updated, as necessary, in this Form 10-Q. The year-end condensed consolidated balance sheet data presented for comparative purposes was derived from audited financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and adjustments) considered necessary for a fair statement have been included. The results of operations for any interim period are not necessarily indicative of, nor comparable to, the results of operations for any other interim period or for a full fiscal year. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Form 10-K. Basis of Consolidation The Company’s fiscal year ends on January 31. The condensed consolidated financial statements of the Company and its subsidiaries have been prepared in conformity with U.S. GAAP. All intercompany transactions and balances have been eliminated upon consolidation. Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies described in Note 1 - Organization and Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 31, 2024. Concentration of Risk The Company’s products are manufactured, assembled and tested by third-party contractors located primarily in Asia. The Company does not have long-term agreements with these contractors. A significant disruption in the operations of one or more of these contractors would impact the production of the Company’s products which could have a material adverse effect on its business, financial condition and results of operations. A substantial portion of the Company’s revenue is derived from sales through its two major distributors and one ODM. WT Microelectronics Co., Ltd., formerly Wintech Microelectronics Co., Ltd., or WT, serves as a non-exclusive sales representative and fulfillment partner in Asia other than Japan, and Hakuto Co., Ltd., or Hakuto, serves as a Japanese distributor. Chicony Electronics Co., Ltd., or Chicony, is an ODM that manufactures devices incorporating the Company’s solutions on behalf of multiple end-customers. Termination of the relationships with these customers could result in a temporary or permanent loss of revenue. Furthermore, any credit issues from these customers could impair their abilities to make timely payment to the Company. See Note 15 for additional information regarding revenue and credit concentration with these customers. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, marketable debt securities and accounts receivable. The Company maintains its cash primarily in checking accounts with reputable financial institutions. Cash deposits held with these financial institutions may exceed the amount of insurance provided on such deposits. The Company has not experienced any losses on deposits of its cash. In order to limit the exposure of each investment, the cash equivalents and marketable debt securities consist primarily of money market funds, fixed deposit accounts, commercial paper, corporate bonds, asset-backed securities and U.S. government securities which management assesses to be highly liquid. The Company does not hold or issue financial instruments for trading purposes. The Company performs ongoing credit evaluation of its customers and adjusts credit limits based upon payment history and customers’ credit worthiness. The Company regularly monitors collections and payments from its customers. Restricted Cash Amounts included in restricted cash represent those required to be set aside to secure certain transactions in a foreign entity. As of July 31, 2024 and January 31, 2024, restricted cash was immaterial, respectively. The following table presents cash, cash equivalents and restricted cash reported on the condensed consolidated balance sheets, and the totals are presented on the condensed consolidated statements of cash flows: As of July 31, January 31, July 31, January 31, (in thousands) Cash and cash equivalents $ 153,925 $ 144,914 $ 122,515 $ 113,541 Restricted cash 7 7 8 8 Total as presented in the condensed consolidated statements of cash flows $ 153,932 $ 144,921 $ 122,523 $ 113,549 Recent Accounting Pronouncements There has been no adoption of any new and recently issued accounting pronouncements. |

In accordance with ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, the Company estimates the expected losses at an individual security level whenever a security’s fair value is below its amortized cost basis using the discounted cash flow method. The credit-related portion of the loss is recognized in other income, net, in the condensed consolidated statements of operations but is limited to the difference between the fair value and the amortized cost basis of the security, adjusted for accrued interest. The non-credit-related portion of the loss is recognized in accumulated other comprehensive loss in the condensed consolidated balance sheets. The credit-related losses were not material for the three and six months ended July 31, 2024 and 2023, respectively. The following fair value hierarchy is applied for disclosure of the inputs used to measure fair value of available-for-sale securities. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments. Level 3—Unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation. The Company measures the fair value of money market funds using quoted prices in active markets for identical assets and classifies them within Level 1. The fair value of other debt securities are obtained based on quoted prices for similar assets in active markets and are classified within Level 2. The following tables present the fair value of available-for-sale securities measured on a recurring basis as of July 31, 2024 and January 31, 2024, respectively: As of July 31, 2024 Total Level 1 Level 2 Level 3 (in thousands) Money market funds $ 1,299 $ 1,299 $ — $ — Commercial paper 17,857 — 17,857 — Corporate bonds 44,528 — 44,528 — Asset-backed securities 10,940 — 10,940 — U.S. government securities 23,868 — 23,868 — Total cash equivalents and marketable debt securities $ 98,492 $ 1,299 $ 97,193 $ — As of January 31, 2024 Total Level 1 Level 2 Level 3 (in thousands) Money market funds $ 296 $ 296 $ — $ — Commercial paper 30,806 — 30,806 — Corporate bonds 38,912 — 38,912 — Asset-backed securities 15,130 — 15,130 — U.S. government securities 20,972 — 20,972 — Total cash equivalents and marketable debt securities $ 106,116 $ 296 $ 105,820 $ — In addition to available-for-sale securities, the Company also has fixed deposit accounts that are classified as cash equivalents. As of July 31, 2024 and January 31, 2024, the carrying value of fixed deposit accounts was approximately $ 9.6 million and $ 7.0 million, respectively, which represented their fair value within level 1 hierarchy. Interest income from financial instruments, including amortization of premiums and accretion of discounts, as well as realized gains and losses from available-for-sale securities, are recorded in other income, net, in the condensed consolidated statements of operations. For the three months ended July 31, 2024 and 2023, interest income and realized gains and losses, net, were approximately $ 2.1 million and $ 1.9 million, respectively. For the six months ended July 31, 2024 and 2023, interest income and realized gains and losses, net, were approximately $ 4.4 million and $ 3.2 million, respectively. The Company's non-marketable equity investments in privately-held companies are measured at cost, adjusted for subsequent observable price change or any impairment. Upon determining that an impairment or observable price change exists, the Company records any adjustment to the fair value through other income, net, in the condensed consolidated statements of operations. There was no significant change in the fair value and there was no impairment loss related to equity investment for the three and six months ended July 31, 2024. There was approximately $ 1.2 million of impairment recognized for the three and six months ended July 31, 2023. As of July 31, 2024 and January 31, 2024, the non-marketable equity investment was approximately $ 1.2 million, respectively, and recorded in other non-current assets in the condensed consolidated balance sheets. |

The Company recorded a benefit for income taxes of $ 3.4 million and $ 1.8 million for the three and six months ended July 31, 2023, respectively. The increases in income tax expense for the three and six months ended July 31, 2024, as compared to the same periods in the prior fiscal year, were primarily due to tax benefit from the release of $ 3.6 million of valuation allowance on the deferred tax assets of Oculii Corp, or Oculii, in fiscal year 2024 that did not recur in the current fiscal year. The Company files federal and state income tax returns in the United States and in various foreign jurisdictions. The Company’s fiscal years 2021 through 2024 are generally open and subject to potential examination by U.S. federal tax authorities. The Company’s fiscal years 2020 through 2024 are generally open and subject to potential examination by state tax authorities. The Company’s fiscal years 2017 to 2024 remain open to examination by foreign tax authorities. Fiscal years outside of the normal statute of limitations remain open to audit by tax authorities due to tax attributes generated in those earlier years, which have been carried forward and may be audited in subsequent years when utilized. The Company regularly assesses the likelihood of adverse outcomes resulting from potential tax examinations to determine the adequacy of its provision for income taxes. These assessments can require considerable estimates and judgments. As of July 31, 2024, the gross amount of unrecognized tax benefits was approximately $ 23.0 million. If the estimates of income tax liabilities prove to be less than the ultimate assessment, then a further charge to expense could be required. If events occur, and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities could result in tax benefits being recognized in the period in which the Company determines the liabilities are no longer necessary. It is reasonably possible that within the next 12 months the Company's unrecognized tax benefits could potentially be reduced by up to $ 9.0 million. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | 14. Commitments and Contingencies Contract Manufacturer Commitments The Company’s components and products are procured and built by independent contract manufacturers based on sales forecasts. These forecasts include estimates of future demand, historical trends, analysis of sales and marketing activities, and adjustment of overall market conditions. The Company regularly issues purchase orders to independent contract manufacturers which are cancelable upon agreement between the Company and third-party manufacturers. These manufacturing purchase commitments typically provide the Company with flexibility to cancel, reschedule or adjust requirements based upon business needs but the Company may incur certain costs depending on the production stage of the products. As of July 31, 2024 and January 31, 2024, total manufacturing purchase commitments were approximately $ 57.5 million and $ 30.7 million, respectively. The Company also reviews and assesses the need for any expected loss liabilities on quarterly basis for all products that it does not expect to sell for which it has committed purchases from suppliers and records the liabilities in accrued and other current liabilities in the condensed consolidated balance sheets. There were no material loss liabilities recorded in the condensed consolidated balance sheets from adverse purchase commitments as of July 31, 2024 and January 31, 2024. Contract Service Commitment In the second quarter of fiscal year 2025, the Company entered into a noncancellable service contract with a third party provider for certain services of its IT infrastructure. As of July 31, 2024, the noncancellable service agreement was approximately $ 5.2 million. There was no material noncancellable service agreement as of January 31, 2024. Indemnification The Company, from time to time, in the normal course of business, indemnifies certain vendors with whom it enters into contractual relationships. The Company has agreed to hold the other party harmless against third-party claims in connection with the Company’s future products. The Company also indemnifies certain customers against third-party claims related to certain intellectual property and product liability matters. It is not possible to determine the maximum potential amount of liability under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstances that are likely to be involved in each particular claim. The Company has no t made payments under these obligations as of July 31, 2024, and no liabilities have been recorded for these obligations in the condensed consolidated balance sheets as of July 31, 2024 and January 31, 2024, respectively. Other Matters From time to time, the Company is subject to commercial disputes, employment issues, intellectual property claims and litigation, in the ordinary course of its business. Although the ultimate disposition of asserted claims cannot be predicted with certainty, it is the Company’s belief that the outcome of any such claims, either individually or on a combined basis, will not have a material adverse effect on its consolidated financial position. The results of any litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors. As of July 31, 2024 and January 31, 2024, there were no accruals for contingent liabilities related to such matters recorded in the condensed consolidated balance sheets. |

Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by the Company in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and, therefore, do not include all information and notes normally provided in audited financial statements. The accounting policies are described in the “Notes to Consolidated Financial Statements” in the Annual Report on Form 10-K for the 2024 fiscal year filed with the SEC on March 29, 2024 (the Form 10-K) and updated, as necessary, in this Form 10-Q. The year-end condensed consolidated balance sheet data presented for comparative purposes was derived from audited financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and adjustments) considered necessary for a fair statement have been included. The results of operations for any interim period are not necessarily indicative of, nor comparable to, the results of operations for any other interim period or for a full fiscal year. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Form 10-K. |
Basis of Consolidation | Basis of Consolidation The Company’s fiscal year ends on January 31. The condensed consolidated financial statements of the Company and its subsidiaries have been prepared in conformity with U.S. GAAP. All intercompany transactions and balances have been eliminated upon consolidation. |
Concentration of Risk | Concentration of Risk The Company’s products are manufactured, assembled and tested by third-party contractors located primarily in Asia. The Company does not have long-term agreements with these contractors. A significant disruption in the operations of one or more of these contractors would impact the production of the Company’s products which could have a material adverse effect on its business, financial condition and results of operations. A substantial portion of the Company’s revenue is derived from sales through its two major distributors and one ODM. WT Microelectronics Co., Ltd., formerly Wintech Microelectronics Co., Ltd., or WT, serves as a non-exclusive sales representative and fulfillment partner in Asia other than Japan, and Hakuto Co., Ltd., or Hakuto, serves as a Japanese distributor. Chicony Electronics Co., Ltd., or Chicony, is an ODM that manufactures devices incorporating the Company’s solutions on behalf of multiple end-customers. Termination of the relationships with these customers could result in a temporary or permanent loss of revenue. Furthermore, any credit issues from these customers could impair their abilities to make timely payment to the Company. See Note 15 for additional information regarding revenue and credit concentration with these customers. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, marketable debt securities and accounts receivable. The Company maintains its cash primarily in checking accounts with reputable financial institutions. Cash deposits held with these financial institutions may exceed the amount of insurance provided on such deposits. The Company has not experienced any losses on deposits of its cash. In order to limit the exposure of each investment, the cash equivalents and marketable debt securities consist primarily of money market funds, fixed deposit accounts, commercial paper, corporate bonds, asset-backed securities and U.S. government securities which management assesses to be highly liquid. The Company does not hold or issue financial instruments for trading purposes. The Company performs ongoing credit evaluation of its customers and adjusts credit limits based upon payment history and customers’ credit worthiness. The Company regularly monitors collections and payments from its customers. |
