Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Business and Significant Accounting Policies	Summary of Business and Significant Accounting Policies Business C3.ai, Inc. (including its subsidiaries, “C3 AI” or “the Company”) is an enterprise artificial intelligence (“AI”) software provider. The Company’s C3 AI Platform supports accelerating digital transformation in various industries with prebuilt and configurable C3 AI Applications for business use cases including predictive maintenance, supply network optimization, energy management, fraud detection, sensor network health, anti-money laundering, and customer engagement. The Company supports customers in the United States, Europe, and other parts of the world. The Company was initially formed as a limited liability company in Delaware on January 8, 2009 and converted to a Delaware corporation in June 2012. Basis of Presentation and Principles of Consolidation The Company prepares its unaudited condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with U.S. GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended April 30, 2024, which was filed with the SEC on June 18, 2024. In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of October 31, 2024 and the results of operations for the three and six months ended October 31, 2024, and cash flows for the six months ended October 31, 2024. The results of operations for the three and six months ended October 31, 2024 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period. The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of the accompanying unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Actual results and outcomes could differ significantly from the Company’s estimates, judgments, and assumptions. Such estimates include, but are not limited to, determining standalone selling price for performance obligations in contracts with customers and estimating variable consideration, the estimated expected benefit period for deferred contract acquisition costs, the useful lives of long-lived assets, the incremental borrowing rate for operating leases, other assumptions used to measure stock-based compensation, and the valuation of deferred income tax assets and uncertain tax positions. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. As future events and their effects cannot be determined with precision, actual results could materially differ from those estimates and assumptions. Fiscal Year The Company’s fiscal year ends on April 30. Summary of Significant Accounting Policies The Company’s significant accounting policies are discussed in Note 1. Summary of Business and Significant Accounting Policies in the Notes to Consolidated Financial Statements in its Annual Report on Form 10-K for the fiscal year ended April 30, 2024, which was filed with the SEC on June 18, 2024. There have been no significant changes to these policies during the three and six months ended October 31, 2024. Recently Issued Accounting Standards Not Yet Adopted In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”) to improve the disclosures regarding a public entity’s reportable segments and address requests from investors for additional, more detailed information about a reportable segment’s expenses. The Company is required to adopt the guidance in the fourth quarter of fiscal 2025, though early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures (“ASU 2023-09”) to provide disaggregated income tax disclosures on rate reconciliation and income taxes paid. The Company is required to adopt the guidance in the fourth quarter of fiscal 2026, though early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income (Topic 220) Disaggregation of Income Statement Expenses (“ASU 2024-03”), to enhance the transparency and decision usefulness of financial information presented in the income statement by requiring disaggregated information about certain income statement expense line items. The Company is required to adopt the guidance in the fourth quarter of fiscal 2028, though early adoption permitted. The Company is currently evaluating the impact of this amendment on its consolidated financial statements.

Revenue	Revenue Disaggregation of Revenue The following table presents revenue by geographical region (in thousands): Three Months Ended October 31, Six Months Ended October 31, 2024 2023 2024 2023 North America (1) $ 84,343 $ 61,179 $ 161,471 $ 122,891 Europe, the Middle East and Africa (1) 9,581 10,607 18,971 20,165 Asia Pacific (1) 14 1,100 261 1,925 Rest of World (1) 400 343 848 610 Total revenue $ 94,338 $ 73,229 $ 181,551 $ 145,591 __________________ (1) The United States comprised 87% and 83% of the Company’s revenue for the three months ended October 31, 2024 and 2023, respectively, and 87% and 84% of the Company’s revenue for the six months ended October 31, 2024 and 2023, respectively. No other country comprised 10% or greater of the Company’s revenue for the three and six months ended October 31, 2024 or 2023. Revenue is recognized at the time the related performance obligation is satisfied with the transfer of a promised good or service to a customer over time. For the significant majority of the Company’s offerings, software and maintenance and support services are highly interdependent and interrelated and represent a single performance obligation within the context of the contract and are generally satisfied over time. Revenue from software licenses that do not require maintenance and support services is recognized when the control of the software is transferred to the customer. Revenue from such software licenses was $19.2 million and $3.8 million during the three months ended October 31, 2024 and 2023, respectively, and $31.8 million and $7.0 million during the six months ended October 31, 2024 and 2023, respectively. Professional Services revenue primarily include service fees and prioritized engineering services. Service fees include revenue from services such as consulting, training, and paid implementation services. For service fees, revenue is typically recognized over time as the services are performed. Prioritized engineering services are undertaken when a customer requests that the Company accelerate the design, development, and delivery of software features and functions that are planned in future product roadmap. When the Company agrees to this, an agreed upon fee is negotiated to accelerate the development of the software as well as other terms, such as relevant specifications. When the software feature is delivered, it becomes integrated to the Company’s core product offering, is available to all subscribers of the underlying software product and enhances the operation of that product going forward. Such prioritized engineering services result in production-level computer software – compiled code that enhances the functionality of our production products – which is available for customers to use over the life of their software licenses. Prioritized engineering services revenue is recognized as professional services over the period in which the software development is completed. Total professional services revenue comprised of (in thousands): Three Months Ended October 31, Six Months Ended October 31, 2024 2023 2024 2023 Prioritized engineering services $ 9,661 $ 4,852 $ 20,310 $ 13,100 Service fees 3,515 1,928 6,623 4,690 Total professional services revenue $ 13,176 $ 6,780 $ 26,933 $ 17,790 Deferred Revenue As of October 31, 2024 and April 30, 2024, the Company’s deferred revenue balances were $35.8 million and $39.0 million, respectively. Revenue of $35.9 million and $40.7 million was recognized during the six months ended October 31, 2024 and 2023, respectively, that was included in the deferred revenue balances as of April 30, 2024 and 2023, respectively. Remaining Performance Obligation Remaining performance obligations are committed and represent non-cancellable contracted revenue that has not yet been recognized and will be recognized as revenue in future periods. Some contracts allow customers to cancel the contracts without a significant penalty, and the cancellable amount of contract value is not included in the remaining performance obligations. The Company excludes amounts related to performance obligations and usage-based royalties that are billed and recognized as they are delivered or billed and recognized in the same period. This primarily consists of monthly usage-based runtime and hosting charges in the duration of some revenue contracts. Revenue expected to be recognized from remaining performance obligations was approximately $260.5 million as of October 31, 2024, which includes $87.8 million of non-cancellable commitments where actual product selection and quantities of specific products or services will be determined at a later date. Approximately $151.6 million is expected to be recognized over the next 12 months and a majority of the remaining amount is expected to be recognized over the next 13 to 48 months. Customer Concentration and Accounts Receivable A majority of the Company’s Customer-Entities consist of corporate and governmental entities. A Customer-Entity is defined as each entity that is the ultimate parent of a party contracting with the Company. A limited number of Customer-Entities have accounted for a large part of the Company’s revenue and accounts receivable to date. For the purpose of determining customer concentration and accounts receivable, unbilled receivables have been excluded from the accounts receivable balance. Two separate Customer-Entities accounted for 18% and 13%, respectively, of revenue for the three months ended October 31, 2024. Two separate Customer-Entities accounted for 25% and 13%, respectively, of revenue for the three months ended October 31, 2023. Two separate Customer-Entities accounted for 20% and 14% respectively, of revenue for the six months ended October 31, 2024. Two separate Customer-Entities accounted for 29% and 13%, respectively, of revenue for the six months ended October 31, 2023. One Customer-Entity accounted for 21% of accounts receivable at October 31, 2024. Two separate Customer-Entities accounted for 25% and 16%, respectively, of accounts receivable at April 30, 2024. Accounts receivable includes billed and unbilled receivables, net of allowance of doubtful accounts. Trade accounts receivable are recorded at invoiced amounts and do not bear interest. The allowance for credit losses is based on the Company’s assessment of the collectability of accounts receivable by considering various factors, including the age of each outstanding invoice, customer type, the collection history of each customer, historical write-off experience, current and near-term macroeconomic conditions and uncertainties. The expectation of collectability is based on a review of credit profiles of customers, contractual terms and conditions, current economic trends, and historical payment experience. Accounts receivable included unbilled receivables as of October 31, 2024 and April 30, 2024 of $97.5 million and $62.3 million, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Non-cancellable Purchase Commitments In the normal course of business, the Company enters into non-cancellable purchase commitments with various parties. As of October 31, 2024, the Company had remaining purchase commitments of $355.0 million related to cloud hosting and associated services and $43.5 million related to professional services due over the next one C3.ai Digital Transformation Institute Grants In February 2020, the Company entered into an agreement establishing the C3.ai Digital Transformation Institute (“C3.ai DTI”), a program established to attract many of the world’s leading research institutions to join in a coordinated and innovative effort to advance the digital transformation of business, government, and society. As part of the agreement, the Company has agreed to issue grants to C3.ai DTI, which are subject to compliance with certain obligations. The grants shall be paid by the Company over five years in the form of cash, publicly traded securities, or other property of equivalent net value. As of October 31, 2024 and April 30, 2024, the total potential remaining contributions are $31.6 million and $31.6 million, respectively. The future grant payments are conditional in nature and subject to execution of the program in line with specific requirements. Leases On August 25, 2021, the Company entered into a new lease to acquire approximately 283,015 square feet of office space in several phases in Redwood City, California. The lease commencement date of the first two phases was determined to have occurred in the quarter ended January 31, 2022, when the landlord delivered the leased space to the Company. The lease commencement date of the third phase was determined to have occurred in the quarter ended October 31, 2022, when the landlord delivered the leased space to the Company. The lease commencement date of the fourth phase was determined to have occurred in the quarter ended April 30, 2023, when the landlord delivered the leased space to the Company. The lease commencement date of the fifth phase was determined to have occurred in the quarter ended July 31, 2023, when the landlord delivered the leased space to the Company. The lease commencement date of the sixth phase was determined to have occurred in the quarter ended January 31, 2024, when the landlord delivered the leased space to the Company. The lease commencement date of the seventh and final phase was determined to have occurred in the quarter ended July 31, 2024, when the landlord delivered the applicable leased space to the Company. The Company recorded $1.3 million of lease liability in other long-term liabilities and corresponding right-of-use asset in other assets, non-current in the condensed consolidated balance sheets related to the seventh phase of the lease. Legal Proceedings Securities Litigation On March 4, 2022, a putative securities class action complaint (captioned The Reckstin Family Trust v. C3.ai, Inc. et al. , 22-cv-01413-HSG) was filed in the U.S. District Court for the Northern District of California against the Company, and certain current and former officers and directors. On December 12, 2022, the court appointed a lead plaintiff and lead counsel. On February 15, 2023, the lead plaintiff and three additional named plaintiffs filed an amended complaint. The amended complaint names as defendants the Company, four current and former officers and directors, the underwriters in the Company’s initial public offering (“IPO”), and Baker Hughes Company (“Baker Hughes”). The amended complaint generally alleges that the defendants made material misstatements or omissions about the Company’s partnership with Baker Hughes and the Company’s own salesforce. The amended complaint alleges that defendants made these misstatements or omissions in connection with the Company’s IPO in violation of Sections 11 and 15 of the Securities Act of 1933 and between December 9, 2020 and December 2, 2021, inclusive, in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The amended complaint further alleges that certain defendants engaged in insider trading in violation of Section 20A of the Securities Exchange Act of 1934. Plaintiffs seek unspecified damages, interest, fees and costs. All defendants moved to dismiss Plaintiffs’ amended complaint on May 1, 2023. On June 30, 2023, Plaintiffs voluntarily dismissed the underwriter defendants. On February 22, 2024, the court granted the motion to dismiss on all claims except for portions of the alleged violations of Section 11 and Section 15. Plaintiffs filed a second amended complaint on April 4, 2024. Defendants filed motions to dismiss on May 17, 2024. Plaintiffs filed an opposition brief on July 15, 2024. While the motions were pending, Plaintiffs filed a motion to amend their second amended complaint on September 27, 2024 to add new factual allegations. The parties have thus stayed the briefing on the motion to dismiss until the motion to amend is resolved. Defendants filed an opposition to the motion to amend on November 12, 2024. Six putative shareholder derivative actions have been filed: (1) Suri v. Siebel et al. (22-cv-03031) filed on May 23, 2022 in the U.S. District Court for the Northern District of California; (2) Rabasca v. Siebel et al. (23-cv-1566) filed on April 3, 2023 in the U.S. District Court for the Northern District of California; and (3) Vo v. Siebel et al. (23-cv-428) filed on April 19, 2023 in the U.S. District Court for the District of Delaware; and (4) Lanfair v. Siebel et al. (24-cv-01869) filed on March 26, 2024 in the U.S. District Court for the Northern District of California; (5) Pankow v. Siebel et al. (2024-0530-NAC) on May 15, 2024 in the Chancery Court of Delaware; and (6) Rosenfeld v. Siebel et al. (2024-0698) on June 28, 2024 in the Chancery Court of Delaware. In these cases, the plaintiffs assert claims on the Company’s behalf against certain of the Company’s current and former officers and directors for breach of fiduciary duty, aiding and abetting breach of fiduciary duty, gross mismanagement, corporate waste, abuse of control, unjust enrichment, and violations of the Securities Exchange Act of 1934 based on allegations similar to those in the securities class action. In all six cases, the Company is named as a nominal defendant. The derivative complaints seek unspecified damages, disgorgement of profits from board member stock sales, an award of costs and expenses, including reasonable attorneys’ fees, and corporate governance reforms. On September 7, 2022, Suri was stayed pending resolution of the Reckstin case. On August 3, 2023, Vo was transferred to the U.S. District Court for the Northern District of California (3:23-cv-03895), and on August 30, 2023, the Vo action was stayed on the same terms as the Suri action. On December 4, 2023, the parties in Rabasca filed a stipulation to consolidate the Rabasca action with the Suri action, and to stay the Rabasca action on the same terms as the Suri action. On July 3, 2024, Lanfair was consolidated with Suri and stayed on the same terms. The Company has not yet been required to answer the complaints in Suri, Rabasca, Vo, and Lanfair. On November 13, 2024, the Pankow action was stayed. The plaintiff in Rosenfeld has refused to stay the matter, and thus the Company filed a motion to stay on November 12, 2024. As of the date of this report, the Company does not believe it is probable that these cases will result in an unfavorable outcome; however, if an unfavorable outcome were to occur in these cases, it is possible that the impact could be material to the Company’s results of operations in the period(s) in which any such outcome becomes probable and estimable. Given that the litigation is still in its preliminary stages, the Company is currently unable to estimate the potential loss or range of loss, if any, that may arise from these matters. On February 27, 2024, the Company filed a lawsuit in the Court of Rome, Italy against Enel Global Services S.r.l. and any involved corporate affiliates (“Enel”). The claims in the suit against Enel include misappropriation of trade secrets under Articles 98 and 99 of the Italian Industrial Property Code and breach of contract. In this action, the Company seeks compensatory damages in the amount of €2.1 billion, equitable and other relief, as well as fees and costs. The Company has also filed a report of criminal misconduct with Italian law enforcement under Article 623 of the Italian Criminal Code. The Company is evaluating other legal venues to fully redress its claims. The Company is considering filing a report of misconduct with federal law enforcement in the United States. Since any legal action is unpredictable, it is difficult to quantify the potential recoveries, associated potential costs, and timeline associated with resolution of this matter. Any gain on this matter is considered a gain contingency and will be recognized in the period in which the award is realized or realizable. In addition, from time to time, the Company is involved in various other legal proceedings arising in the ordinary course of business. Apart from the foregoing, the Company is not presently a party to any other such litigation the outcome of which, the Company believes, if determined adversely to the Company, would individually, or taken together, have a material adverse effect on the Company’s business, operating results, cash flows, or financial condition.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation On November 27, 2020, the Company’s board of directors adopted, and its stockholders approved, the 2020 Incentive Plan, which became effective in connection with the IPO. The 2020 Incentive Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit (“RSU”) awards, performance awards and other equity awards. The number of shares of Class A common stock reserved for issuance under the 2020 Incentive Plan is subject to automatic evergreen increases annually through (and including) May 1, 2030 pursuant to the terms of the 2020 Incentive Plan. There was an automatic annual increase on May 1, 2024 in the number of shares reserved for future issuance pursuant to the 2020 Incentive Plan in an amount equal to seven percent (7%) of the total number of shares of the Company’s Class A common stock and Class B common stock outstanding on April 30, 2024. Stock Options Stock options generally expire 10 years from the date of grant, or earlier if services are terminated. Generally, each stock option for common stock is subject to a vesting schedule such that one fifth of the award vests after the first-year anniversary and one-sixtieth of the award vests each month thereafter over the remaining four years, subject to continuous service. A summary of the Company’s option activity during the six months ended October 31, 2024 is as follows: Options Outstanding Number of Weighted Weighted Aggregate (in thousands) (in thousands) Balance as of April 30, 2024 31,328 $ 13.97 5.68 $ 268,167 Options granted 1,187 23.43 Options exercised (1,064) 25.82 Options cancelled (513) 19.77 Balance as of October 31, 2024 30,938 $ 14.56 5.41 $ 311,547 Vested and exercisable as of October 31, 2024 24,887 $ 11.30 4.89 $ 331,739 Vested and expected to vest as of October 31, 2024 30,938 $ 14.56 5.41 $ 311,547 As of October 31, 2024, there was $74.8 million of unrecognized compensation cost related to stock options which is expected to be recognized over an estimated weighted-average period of 2.2 years. The grant-date fair value of the options issued for the six months ended October 31, 2024 is estimated on the date of grant using the Black-Scholes-Merton option pricing model. The weighted average assumptions underlying the fair value estimation are provided in the following table: Six Months Ended October 31, 2024 2023 Valuation assumptions: Expected dividend yield — % — % Expected volatility 66.2 % 62.3 % Expected term (years) 6.1 6.5 Risk-free interest rate 3.6 % 4.7 % Restricted Stock Units The Company’s RSUs include time-based RSUs and performance-based RSUs with market conditions (“PRSUs”). Time-based RSUs The time-based RSUs are typically subject to service-based vesting conditions satisfied over five years with one-fifth of the award vesting after the first-year anniversary and one-twentieth of the award vesting quarterly thereafter. The related stock-based compensation is recognized on a straight-line basis over the requisite service period. PRSUs In July 2022, the compensation committee of the board of directors (the “Compensation Committee”) approved the grant of a maximum of 1,700,000 performance-based restricted stock units (the “PRSU Award”) to the CEO pursuant to the 2020 Incentive Plan, subject to and conditioned upon the subsequent determination by the board of directors of performance metrics upon the achievement of which the PRSU Award would vest. In August 2022, the board of directors approved performance metrics in concept, subject to further action by the Compensation Committee. In December 2022, the Compensation Committee: (a) determined and approved the performance metrics, which are based on the achievement of certain total shareholder return results, as measured against certain stock price hurdles (the “Market Condition”); and (b) extended the vesting period of the PRSU Award through December 31, 2027. As an additional condition to vesting of each tranche of the PRSU Award, Mr. Siebel must remain in continuous service to the Company through a minimum service date that applies to such tranche or, if later, the date the applicable performance metric is achieved (the “Service Condition”). The grant date of the PRSU Award was established in December 2022. Stock-based compensation expense associated with the PRSU Award will be recognized over the longer of the expected achievement period for the Market Condition or the Service Condition. For the six months ended October 31, 2024, the Company recorded stock-based compensation expense of $2.4 million related to the PRSU Award. The Company determined the grant date fair value of the PRSU Award using a Monte Carlo simulation model with the following assumptions: stock price of $12.90, risk-free interest rate of 3.7%, dividend yield of 0% and expected volatility of 51.4%. A summary of the Company’s RSU activity during the six months ended October 31, 2024 is as follows: RSUs Outstanding Number of RSUs Weighted Average (in thousands) Unvested Balance as of April 30, 2024 19,283 $ 24.26 RSUs granted 7,569 27.21 RSUs vested (3,858) 26.50 RSUs forfeited (2,515) 27.35 Unvested Balance as of October 31, 2024 20,479 $ 25.11 As of October 31, 2024, there was $473.9 million of unrecognized stock-based compensation expense related to outstanding RSUs granted to employees that is expected to be recognized over a weighted-average period of 3.7 years. In fiscal year 2025 and 2024, the Compensation Committee approved the payment of fiscal year 2024 and 2023 bonuses, respectively, under the Company’s annual bonus program in the form of fully vested RSUs covering shares of Class A common stock to employees. The Company issued 750,591 and 532,842 shares of Class A common stock pursuant to this program in the six months ended October 31, 2024 and 2023, respectively. Shares issued in settlement of fully vested RSUs granted under this bonus program were issued from the 2020 Incentive Plan and reduced the shares available for issuance under the 2020 Incentive Plan. Employee Stock Purchase Plan On November 27, 2020, the Company’s board of directors also adopted, and its stockholders also approved, the 2020 Employee Stock Purchase Plan (the “2020 ESPP”), which became effective immediately prior to the IPO. The 2020 ESPP authorizes the issuance of shares of Class A common stock pursuant to purchase rights granted to employees. A total of 3,000,000 shares of Class A common stock were initially reserved for future issuance under the 2020 ESPP. The number of shares of Class A common stock reserved for issuance under the 2020 ESPP is subject to automatic evergreen increases annually through (and including) May 1, 2030 pursuant to the terms of the 2020 ESPP. There was an automatic annual increase on May 1, 2024 in the number of shares reserved for future issuance pursuant to the 2020 ESPP in an amount equal to one percent (1%) of the total number of shares of the Company’s Class A common stock and Class B common stock outstanding on April 30, 2024. The 2020 ESPP permits participants to purchase shares of Class A common stock in an amount not exceeding 15% of their earnings during the relevant offering period. The offering dates and purchase dates for the 2020 ESPP are determined at the discretion of the Company’s board of directors. Except for the initial offering period under the 2020 ESPP, which commenced on October 16, 2022 and ends on September 15, 2024, the 2020 ESPP provides for 24-month offering periods beginning September 15 and March 15 of each year, with each offering period consisting of four six-month purchase periods. The 2020 ESPP allows eligible employees to purchase shares of the Company’s Class A common stock, subject to purchase limits of 2,500 shares during each six-month period or $25,000 worth of stock for each calendar year, through payroll deductions at price per share equal to 85% of the lesser of the fair market value of the Company’s Class A common stock on (i) the first trading day of the applicable offering period and (ii) the last trading day of each purchase period in the applicable offering period. If the price per share of the Company’s Class A common stock on any purchase date in the offering period is lower than the price per share of the Company’s Class A common stock price on the enrollment date of that offering period, the offering period will immediately reset after the purchase of shares on such purchase date and automatically roll into a new 24-month offering period. The Company uses a Black-Scholes-Merton option pricing model to determine the fair value of employee stock purchase rights granted under the 2020 ESPP. The following assumptions were used to calculate the fair value of shares to be granted under the 2020 ESPP during the period: Six Months Ended October 31, 2024 2023 Valuation assumptions: Expected dividend yield — % — % Expected volatility 56.2 - 75.3% 64.0 - 70.1% Expected term (years) 0.5 - 2.0 0.5 - 2.0 Risk-free interest rate 3.6 - 4.6% 5.0 - 5.5% During the six months ended October 31, 2024 and 2023, the Company recognized $2.3 million and $3.1 million, respectively, of stock-based compensation expense related to 2020 ESPP. As of October 31, 2024, there was $8.2 million of unrecognized stock-based compensation expense that is expected to be recognized over the remaining term of the respective offering periods. Stock-based Compensation Expense The following table summarizes the effects of stock-based compensation on the Company’s condensed consolidated statements of operations (in thousands): Three Months Ended October 31, Six Months Ended October 31, 2024 2023 2024 2023 Cost of subscription $ 7,827 $ 8,514 $ 15,521 $ 16,570 Cost of professional services 484 479 1,198 939 Sales and marketing 20,802 18,226 39,635 35,005 Research and development 17,999 16,685 36,430 33,718 General and administrative 9,926 9,265 18,937 17,817 Total stock-based compensation expense $ 57,038 $ 53,169 $ 111,721 $ 104,049 The Company records stock-based compensation associated with the Company’s annual bonus program and retention bonus program for certain employees, which may be paid out in fully vested RSUs that are settled in shares of Class A common stock. During the six months ended October 31, 2024, the Company recognized $25.8 million of stock-based compensation expense associated with these programs. As of October 31, 2024, $27.8 million and $10.5 million were reflected under accrued compensation and employee benefits and other long-term liabilities, respectively, in the consolidated balance sheets. Upon settlement, this amount will be reflected under common stock and additional paid-in capital in the condensed consolidated statements of stockholders’ equity.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Accounting for income taxes for interim periods generally requires the provision for income taxes to be determined by applying an estimate of the annual effective tax rate for the full fiscal year to income or loss before income taxes, adjusted for discrete items, if any, for the reporting period. The Company updates its estimate of the annual effective tax rate each quarter and makes a cumulative adjustment in such period. The Company recorded income tax expense of $0.3 million and $0.2 million for the three months ended October 31, 2024 and 2023, and $0.5 million and $0.4 million for the six months ended October 31, 2024 and 2023, respectively. Income tax expense consists primarily of income taxes in foreign jurisdictions in which the Company conducts business. Due to the Company’s history of losses in the United States, a full valuation allowance on substantially all of the Company’s deferred tax assets, including net operating loss carryforwards, research and development tax credits, and other book versus tax differences, was maintained.

Net Loss Per Share Attributable to Common Stockholders	Net Loss Per Share Attributable to Common Stockholders Basic net loss per share was the same as diluted net loss per share for the periods presented because the Company was in a loss position for the three and six months ended October 31, 2024 and 2023. For purposes of this calculation, stock options, RSUs, Class A common stock issuable in connection with the 2020 ESPP and early exercised stock options subject to repurchase are considered to be potential common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive. The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders (in thousands, except per share data): Three Months Ended October 31, Six Months Ended October 31, 2024 2023 2024 2023 Numerator Net loss attributable to common stockholders $ (65,972) $ (69,780) $ (128,799) $ (134,138) Denominator Weighted-average shares used in computing net loss per share attributable to Class A and Class B common stockholders, basic and diluted 127,870 118,656 126,434 117,125 Basic and diluted net loss per share attributable to common stockholders Basic and diluted net loss per Class A and Class B common shares $ (0.52) $ (0.59) $ (1.02) $ (1.15) The potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the period presented because including them would have had an antidilutive effect were as follows (in thousands): As of October 31, 2024 2023 Stock options 30,938 32,001 RSUs 20,479 22,460 ESPP 1,075 1,223

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation and Principles of Consolidation The Company prepares its unaudited condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with U.S. GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended April 30, 2024, which was filed with the SEC on June 18, 2024. In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of October 31, 2024 and the results of operations for the three and six months ended October 31, 2024, and cash flows for the six months ended October 31, 2024. The results of operations for the three and six months ended October 31, 2024 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period.
Principles of Consolidation	The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the accompanying unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Actual results and outcomes could differ significantly from the Company’s estimates, judgments, and assumptions. Such estimates include, but are not limited to, determining standalone selling price for performance obligations in contracts with customers and estimating variable consideration, the estimated expected benefit period for deferred contract acquisition costs, the useful lives of long-lived assets, the incremental borrowing rate for operating leases, other assumptions used to measure stock-based compensation, and the valuation of deferred income tax assets and uncertain tax positions. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. As future events and their effects cannot be determined with precision, actual results could materially differ from those estimates and assumptions.
Fiscal Year	Fiscal Year The Company’s fiscal year ends on April 30.
Recently Issued Accounting Standards Not Yet Adopted	Recently Issued Accounting Standards Not Yet Adopted In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”) to improve the disclosures regarding a public entity’s reportable segments and address requests from investors for additional, more detailed information about a reportable segment’s expenses. The Company is required to adopt the guidance in the fourth quarter of fiscal 2025, though early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures (“ASU 2023-09”) to provide disaggregated income tax disclosures on rate reconciliation and income taxes paid. The Company is required to adopt the guidance in the fourth quarter of fiscal 2026, though early adoption is permitted. The Company is currently evaluating the impact of this amendment on its consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income (Topic 220) Disaggregation of Income Statement Expenses (“ASU 2024-03”), to enhance the transparency and decision usefulness of financial information presented in the income statement by requiring disaggregated information about certain income statement expense line items. The Company is required to adopt the guidance in the fourth quarter of fiscal 2028, though early adoption permitted. The Company is currently evaluating the impact of this amendment on its consolidated financial statements.
