Summary of Business and Significant Accounting Policies	Jan. 31, 2021
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. and subsidiaries, or collectively, C3 AI or the Company, is an enterprise artificial intelligence, or AI, software provider. Our C3 AI Suite supports accelerating digital transformation in various industries with prebuilt and configurable C3 AI Applications for business use cases including predictive maintenance, fraud detection, sensor network health, supply network optimization, energy management, anti-money laundering, and customer engagement. The Company supports customers in the United States, Europe, and the rest 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. Reverse Stock Split In November 2020, the Company amended and restated its certificate of incorporation to effect a reclassification of the Company’s prior Class B common stock and Class C common stock into Class A common stock and redeemable convertible Class B-1 common stock into a new redeemable convertible Class A-1 common stock. The rights, including the liquidation, dividend, and voting rights, are substantially identical for each class of common stock reclassified. All references to prior Class B common stock and Class C common stock have been recast to Class A common stock, and all references to redeemable convertible Class B-1 common stock have been recast to redeemable convertible Class A-1 common stock in these unaudited condensed consolidated financial statements to give retrospective effect to the reclassification for all periods presented. The Company also authorized a new Class B common stock. The rights, including the liquidation and dividend rights, of the Class A common stock and the new Class B common stock are substantially identical, other than the voting rights and conversion rights upon transfer of the Class B common stock. See Note 9 for more information. Additionally, the Company effected a 6-for-1 reverse stock split of the Company’s outstanding common stock, preferred stock, and stock option awards. The par value of the common stock and preferred stock was not adjusted as a result of the reverse stock split. The authorized shares of the Class A common stock, new Class A-1 common stock, new Class B common stock and preferred stock were also adjusted to 390,000,000 shares, 6,666,667 shares, 21,000,000 shares, and 233,107,379 shares, respectively. All authorized, issued, and outstanding shares of common stock, preferred stock, stock option awards, and per share data included in these financial statements have been recast to give retrospective effect to the adjusted authorized shares and reverse stock split for all periods presented. Initial Public Offering and Concurrent Private Placements In December 2020, the Company completed its initial public offering (“IPO”), in which the Company issued and sold 17,825,000 shares of its Class A common stock at $42.00 per share, which included 2,325,000 shares issued upon the exercise of the underwriters’ over-allotment option to purchase additional shares. The Company received net proceeds of $694.6 million after deducting underwriting discounts and other offering expenses. In connection with the IPO: •all 33,628,776 shares of the Company’s outstanding redeemable convertible preferred stock, except the Series A* preferred stock, automatically converted into an equivalent number of shares of Class A common stock on a one-to-one basis; •all 3,499,992 shares of the Company’s outstanding redeemable convertible Series A* preferred stock automatically converted into an equivalent number of shares of our Class B common stock on a one-to-one basis; •all 6,666,665 shares of the Company’s outstanding redeemable convertible Class A-1 common stock automatically converted into an equivalent number of shares of Class A common stock on a one-to-one basis; and •the Company amended and restated its certificate of incorporation which became effective upon completion of the IPO. Deferred offering costs consist primarily of direct and incremental accounting, legal and other fees related to the Company’s IPO. Prior to the IPO, all deferred offering costs incurred were capitalized and included in other assets on the condensed consolidated balance sheet. Upon completion of the IPO, $7.2 million of deferred offering costs were reclassified into stockholders’ equity as a reduction of the IPO proceeds. The Company also completed a concurrent private placement immediately subsequent to the closing of the IPO, in which the Company issued and sold 2,380,952 and 1,190,476 shares of its Class A common stock at $42.00 per share to Spring Creek Capital LLC, an affiliate of Koch Industries, Inc., and Microsoft Corporation, respectively (the “Concurrent Private Placement”). The Company received aggregate proceeds of $150.0 million and did not pay underwriting discounts with respect to the shares of Class A common stock that were sold in the Concurrent Private Placement. 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, or 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 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 final prospectus dated December 8, 2020, and filed with the SEC pursuant to Rule 424(b)(4) on December 9, 2020 (the “Final Prospectus”). 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 January 31, 2021, and the results of operations for the three and nine months ended January 31, 2021. The results of operations for the three and nine months ended January 31, 2021, 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 C3.ai, Inc. 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 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. Significant estimates include 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 value of common stock and 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 Prospectus. There have been no significant changes to these policies during the three months ended January 31, 2021. Concentration of Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of cash and cash equivalents, investments and accounts receivable. The majority of the Company’s cash and cash equivalents are held by one financial institution. The Company is exposed to that financial institution to the extent that its cash balance with that financial institution is in excess of Federal Deposit Insurance Company, or FDIC, insurance limits. The Company’s investment policy is to invest in securities with a minimum rating of P1 by Moody’s, A1 by Standard & Poor’s, F-1 by Fitch’s or higher for short-term investments, and minimum rating of A2 by Moody’s, A by Standard & Poor’s, or A by Fitch’s or higher for long-term investments. Recent Accounting Pronouncements The Company currently qualifies as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Accordingly, the Company is provided the option to adopt new or revised accounting guidance either (1) within the same periods as those otherwise applicable to public business entities or (2) within the same time periods as private companies, including early adoption when permissible. The Company has elected to adopt new or revised accounting guidance within the same time period as private companies. Other than policies noted below, there have been no significant changes to the accounting policies disclosed in Note 1 of the audited consolidated financial statements as of and for the years ended April 30, 2020 and 2019 included in the Final Prospectus. Recently Adopted Accounting Standards—In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires a financial asset measured at amortized cost basis to be presented at the net amount expected to be collected. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. The guidance also limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and requires the reversal of previously recognized credit losses if fair value increases. The guidance is effective for the fiscal year beginning May 1, 2023 with early adoption permitted. The Company early adopted the guidance as of May 1, 2020 using a prospective transition method. Adoption of this guidance did not have a material impact to the Company’s consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2018-04 simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The guidance is effective for the fiscal year beginning May 1, 2023 with early adoption permitted. The Company early adopted the guidance as of May 1, 2020 using a prospective transition method. Adoption of this guidance did not have a material impact to the Company’s consolidated financial statements and related disclosures. In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815) I. Accounting for Certain Financial Instruments with Down Round Features II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. Part I of this standard applies to entities that issue financial instruments such as warrants, convertible debt or redeemable convertible preferred stock that contain down-round features. Part II of this standard replaces the indefinite deferral for certain mandatorily redeemable noncontrolling interests and mandatorily redeemable financial instruments of nonpublic entities contained within ASC Topic 480 with a scope exception and does not impact the accounting for these mandatorily redeemable instruments. The Company adopted the guidance as of May 1, 2020 using a prospective transition method. Adoption of this guidance did not have a material impact to the Company’s consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements with respect to Level 3 rollforwards, timing of liquidation of investments in certain entities that calculate net asset value, and measurement uncertainty. The Company adopted the guidance as of May 1, 2020 using a prospective transition method. Adoption of this guidance did not have a material impact to the Company’s consolidated financial statements and related disclosures. Recently Issued Accounting Standards Not Yet Adopted—In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to defer and recognize as an asset. The guidance is effective for the fiscal year beginning May 1, 2021. Early adoption is permitted. The Company is currently evaluating the effect that this guidance will have on the consolidated financial statements and related disclosures.

Significant changes in the deferred revenue balances during the nine months ended January 31, 2021 and 2020 were as follows (in thousands):


	Deferred Revenue
April 30, 2020	$	60,295
Performance obligations satisfied during the period that were included in the deferred revenue balance at the beginning of the year	(53,086)
Increases due to invoicing prior to satisfaction of performance obligations	55,101

Increases due to invoicing prior to satisfaction of performance obligations	$	52,345
January 31, 2020	$	70,893

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. 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 $247.5 million as of January 31, 2021 of which $131.1 million is expected to be recognized over the next 12 months and the remainder thereafter.

Customer Concentration and Accounts Receivable

All of the Company’s customers consist of corporate and governmental entities. A limited number of customers have accounted for a large part of the Company’s revenue and accounts receivable to date. Two separate customers accounted for 16% and 12%, respectively, of revenue for the three months ended January 31, 2021. Two separate customers accounted for 24% and 10%, respectively, of revenue for the three months ended January 31, 2020. Two separate customers accounted for 16% and 12%, respectively, of revenue for the nine months ended January 31, 2021. Two separate customers accounted for 27% and 10%, respectively, of revenue for the nine months ended January 31, 2020. Three separate customers accounted for 21%, 13%, and 11% of accounts receivable at January 31, 2021. Three separate customers accounted for 33%, 19%, and 15% of accounts receivable at April 30, 2020.

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 expectation of collectability is based on a review of credit profiles of customers, contractual terms and conditions, current economic trends, and historical payment experience. The Company regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice and the collection history of each customer to determine the appropriate amount of allowance for doubtful accounts. Accounts receivable included unbilled receivables of as of January 31, 2021 and April 30, 2020 of $0.6 million and $0.5 million, respectively.

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Fair Value Disclosures [Abstract]

Fair Value Measurements

The Company’s financial instruments consist primarily of cash and cash equivalents, marketable debt securities, accounts receivable, non-marketable equity securities, and accounts payable. Cash and cash equivalents and marketable debt securities are reported at their respective fair values on the consolidated balance sheets. Non-marketable equity securities are reported at cost less impairment. The remaining financial instruments are reported on the consolidated balance sheets at amounts that approximate current fair values.

The following table summarizes the types of assets measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands):

The estimated fair value of securities classified as Level 2 financial instruments was determined based on third-party pricing services. The pricing services utilize industry standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. Inputs used for fair value measurement categorized as Level 2 include benchmark yields, reported trades, broker or dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications.

Commitments and Contingencies	Commitments and Contingencies Noncancelable Purchase Commitments The Company entered into a noncancelable arrangement with a web-hosting services provider in November 2019. Under the arrangement, the Company committed to spend an aggregate of at least $30.0 million between November 2019 and November 2022, with a minimum amount of $10.0 million in each of the three years, on services with this vendor. The Company has incurred costs totaling $3.5 million, $2.0 million, $9.6 million and $2.0 million under the arrangement during the three months ended January 31, 2021 and 2020 and the nine months ended January 31, 2021 and 2020, respectively. 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 January 31, 2021 and April 30, 2020 the total potential remaining contributions are $44.6 million and $45.8 million, respectively. The future grant payments are conditional in nature and subject to execution of the program in line with specific requirements. Legal Proceedings The Company is involved in various legal proceedings and periodically receives claims arising in the ordinary course of business. In the Company’s opinion, resolution of these matters is not expected to have a material adverse impact on its consolidated statement of operations, cash flows, or balance sheet. Blattman et al. v. Siebel et al., 15-cv-00530 (D. Del.) On October 28, 2014, Eric Blattman and other former unitholders of E2.0 LLC (E2.0) filed suit in federal court against Thomas M. Siebel and David Schmaier, alleging violation of Section 10(b) of the Securities Exchange Act of 1934 and common law fraud based on alleged misrepresentations made during negotiations leading up to an April 30, 2012 merger between E2.0 and the Company. Plaintiffs thereafter amended their complaint to add the Company as a defendant, and to add breach of contract claims based on alleged violations of certain earn-out and indemnification provisions in the parties’ merger agreement. A bench trial was held in February 2019, and in a January 29, 2020 opinion the court ruled in favor of defendants the Company, Siebel and Schmaier on all claims. The court also awarded defendants their reasonable attorneys’ fees and costs in defending the action. In February 2020, Plaintiffs appealed only the portion of the district court’s ruling related to the alleged breach of contract indemnification claim to the Third Circuit Court of Appeals, seeking damages of approximately $2.5 million. Plaintiffs also seek to overturn the district court’s ruling that defendants are entitled to attorneys’ fees, and contend that plaintiffs instead should recover their attorneys’ fees. No appeal was taken with respect to the ruling in Defendants’ favor on the remaining claims. On February 17, 2021, the Third Circuit affirmed the judgment and orders of the district court in the Company’s and defendants’ favor. The Company intends to seek recovery of its attorneys’ fees and costs as previously awarded by the district court.

As of January 31, 2021 there were no shares of Preferred Stock issued or outstanding. Common Stock The Company has authorized the issuance of 1,000,000,000 shares of Class A common stock and 3,500,000 shares of Class B common stock. The shares of Class A common stock and Class B common stock are identical, except with respect to voting, conversion, and transfer rights. Each share of Class A common stock is entitled to one vote. Each share of Class B common stock is entitled to 50 votes. Class A and Class B common stock have a par value of $0.001 per share and are referred to as common stock throughout the notes to the unaudited condensed consolidated financial statements, unless otherwise noted. Holders of common stock are entitled to receive any dividends as may be declared from time to time by the board of directors. Shares of Class B common stock may be converted to Class A common stock at any time at the option of the stockholder. Each share of Class B common stock will be automatically converted into one share of Class A common stock upon the earliest of the following: (i) the date that is six months following the death or incapacity of Mr. Siebel; (ii) the date that is six months following the date that Mr. Siebel is no longer providing services to the Company as an officer, employee, director, or consultant; (iii) December 11, 2040, which is the twentieth anniversary of the completion of the IPO; or (iv) the date specified by the holders of a majority of the then outstanding shares of Class B common stock, voting as a separate class.

Common Stock Subject to Repurchase Under the Company’s Amended and Restated 2012 Equity Incentive Plan (the “2012 Incentive Plan”), optionholders are allowed to exercise stock options to purchase Class A common stock prior to vesting. The Company has the right to repurchase at the original purchase price any unvested but outstanding common shares upon termination of service of the optionholder. The consideration received for an early exercise of a stock option is considered to be a deposit of the exercise price and the related amount is recorded as a liability. The net proceeds during the three months ended January 31, 2021 and 2020 and the nine months ended January 31, 2021 and 2020 were $4.5 million, $0.3 million, $6.0 million and $1.6 million, respectively. The liability is reclassified into equity on a ratable basis as the stock options vest. Unvested Class A common stock of 1,300,185 and 663,763 shares as of January 31, 2021 and April 30, 2020, respectively were subject to such repurchase right and are legally issued and outstanding as of each period presented.

The repurchase transactions for vested stock options were conducted as net cash settlements where the holders of vested stock options received the difference between the repurchase price and the respective option exercise price. The total net transaction price was $28.5 million. The Company recognized $24.9 million in compensation expense during the nine months ended January 31, 2020 related to the shares repurchased for the difference between the repurchase price and the fair value of the Company’s common stock at the time of repurchase.

Stock-Based Compensation

9 Months Ended

Jan. 31, 2021

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-Based CompensationOn June 29, 2012, the Company adopted the 2012 Incentive Plan. The 2012 Incentive Plan provided for the grant of stock-based awards to employees, non-employee directors, and other service providers of the Company. The 2012 Incentive Plan was terminated in December 2020 in connection with the IPO but continues to govern the terms of outstanding awards that were

granted prior to the termination of the 2012 Incentive Plan. No further equity awards will be granted under the 2012 Incentive Plan. With the establishment of the 2020 Equity Incentive Plan (the “2020 Incentive Plan”) as further discussed below, upon the expiration, forfeiture, cancellation, or reacquisition of any shares of Class A common stock underlying outstanding stock-based awards granted under the 2012 Plan, an equal number of shares of Class A common stock will become available for grant under the 2020 Plan (the “Returning Shares”).

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, nonstatutory stock options, stock appreciation rights, restricted stock awards, RSU awards, performance awards and other equity awards. A total of 67,535,205 shares of the Company’s Class A common stock have been reserved for issuance under the 2020 Incentive Plan in addition to annual automatic evergreen increases in the number of shares of Class A common stock reserved for issuance under the 2020 Incentive Plan. As of January 31, 2021, there were no grants of stock appreciation rights, restricted stock awards, RSU awards, performance awards or other equity awards.

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 common stock pursuant to purchase rights granted to employees. A total of 3,000,000 shares of the Company’s Class A common stock have been reserved for future issuance under the 2020 ESPP in addition to annual automatic evergreen increases in the number of shares of Class A common stock reserved for issuance under the 2020 ESPP. The 2020 ESPP permits participants to purchase shares of common stock of up to 15% of their earnings. The offering dates and purchase dates for the 2020 ESPP are determined at the discretion of the Company’s board of directors. As of January 31, 2021, the Company had not yet launched its 2020 ESPP.

Stock Options to Acquire Class A Common Stock

These 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 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.

As of January 31, 2021, the remaining shares of Class A common available for issuance under the 2020 Incentive Plan was 67,535,205 shares.

A summary of the Company’s option activity during the periods indicated was as follows:

Vested and expected to vest as of January 31, 2021	41,161	$	6.12	8.07	$	460,444

The weighted average grant date fair value of options granted during the nine months ended January 31, 2021 was $6.01. Aggregate intrinsic value represents the difference between the estimated fair value of the underlying common stock and the exercise price of outstanding in-the-money options. The total intrinsic value of options exercised during the nine months ended January 31, 2021 was $52.4 million. The total grant date fair value of options vested during the nine months ended January 31, 2021 was $10.6 million.

As of January 31, 2021, there was $104.0 million of unrecognized compensation cost related to stock options which are expected to be recognized over an estimated weighted-average period of 4.2 years.

The grant-date fair value of the options issued for the nine months ended January 31, 2021 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:


	Nine Months Ended January 31, 2021

Shareholder Loan

In January 2018, in connection with the Series F preferred stock financing, the Company issued 1,251,921 shares of Series F preferred stock in exchange for a note receivable of $24.5 million from its chief executive officer (“CEO”). Prior to the automatic conversion of all Series F preferred stock outstanding into Class A common stock upon the completion of the IPO, the underlying shares of Series F preferred stock were legally outstanding though were not included in the carrying amounts of preferred stock as the note receivable is treated as an equity classified stock-based option grant. In September 2020, the Company’s CEO paid the outstanding full recourse promissory note and accrued interest in the amount of $26.0 million. No interest income was recorded for the note.

Income Taxes	9 Months Ended
Income Taxes	Jan. 31, 2021
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 $0.2 million, $0.1 million, $0.5 million and $0.3 million for the three months ended January 31, 2021 and 2020 and the nine months ended January 31, 2021 and 2020, 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. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted by the United States on March 27, 2020. The CARES Act did not have a material impact on the Company’s provision for income taxes for the three and nine months ended January 31, 2021.

Net Loss Per Share Attributable to Common Stockholders

9 Months Ended

Jan. 31, 2021

Earnings Per Share [Abstract]

Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. Class A and B common shares have identical liquidation and distribution rights. Prior to the automatic conversion of all shares of redeemable convertible Class A-1 common stock into Class A common stock upon the completion of the IPO, the shares of redeemable convertible Class A-1 common stock had a liquidation preference, but were legal form common stock and participated in losses equally with all common stockholders.

Prior to the automatic conversion of all of its redeemable convertible preferred stock outstanding into Class A and Class B common stock upon the completion of the IPO, the Company considered all redeemable convertible preferred stock to be participating securities because they participated in any dividends declared on the Company’s common stock on an as-if-converted basis. Redeemable convertible preferred stock did not participate in the net loss per share with common stockholders as the holders of the convertible preferred did not have a contractual obligation to share in the Company’s losses.

Accordingly, under the two-class method, the net loss is not allocated to the redeemable convertible preferred stock such that the resulting net loss for all periods presented was allocated on a proportionate basis to shares of Class A, Class A-1, and Class B common stock for the number of days that each class was issued and outstanding during the period.

Basic net loss per share attributable to common stockholders is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. Diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period to the extent they are dilutive. For purposes of this calculation, the convertible preferred, stock options, 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 for all periods presented. 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 quarters ended January 31, 2021 and 2020 and the years ended April 30, 2020 and 2019.

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):

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Shareholder Loan In January 2018, the Company issued 1,251,921 shares of Series F Preferred Stock in exchange for a non-recourse promissory note to Thomas M. Siebel, the Company’s CEO, in the amount of $24.5 million. The promissory note has a term of five years with the ability to renew for up to four successive one year periods and bears interest at a rate of 2.18% per annum, compounded annually. In September 2020, Mr. Siebel paid the outstanding promissory note in full including accrued interest in the total amount of $26.0 million. Refer to Note 9 for more information. Secondary Transactions In October 2019, two secondary transactions occurred for total proceeds of $50.0 million each. The CEO sold 1,685,979 shares of Series D preferred and 193,489 shares of Series E preferred, each at a price of $26.6034 per share, to an existing stockholder. Additionally, the CEO sold 584,795 shares of Series C* preferred, 825,012 shares of Series D preferred, and 673,526 shares of redeemable convertible Class A-1 common stock at a price of $24.0000 per share to an existing stockholder. Stock-based compensation expense was not recognized in connection with these secondary transactions as the purchase price was equal to fair value in respect of the redemption and liquidation features of the shares sold at the time of sale. In October 2019, the Company also completed a tender offer to repurchase Class A common stock and vested stock options from employees, including officers, at a price of $30.2310 per share. Refer to Note 8 for more information. Revenue Transactions with Baker Hughes Company In June 2019, the Company entered into multiple agreements with Baker Hughes Company (“Baker Hughes”) under which Baker Hughes received a three-year subscription to use the Company’s software. These agreements were revised in June 2020 to extend the term to five years and modify the subscription fees due. Under the revised agreements, Baker Hughes has made minimum, non-cancelable revenue commitments, which are inclusive of their direct subscription fees and third party revenue generated through the joint marketing arrangement with Baker Hughes, in the amount of $46.7 million in fiscal year 2020, $53.3 million in fiscal year 2021, $75.0 million in fiscal year 2022, $125.0 million in fiscal year 2023, and $150.0 million in fiscal year 2024. During the nine months ended January 31, 2021, the Company recognized total revenue of $21.6 million related to this arrangement. For future periods, any shortfalls against the total annual revenue commitment made to us by Baker Hughes will be assessed and recorded at the end of the fourth quarter of each fiscal year. Under the joint marketing arrangement, the Company is obligated to pay the Baker Hughes a sales commission on subscriptions and services offerings it resells in excess of these minimum revenue commitments. The Company did not incur any sales commission related to this arrangement during the three months ended January 2021 and 2020 and the nine months ended January 2021 and 2020. The Company recognized subscription revenue from direct subscription fees from Baker Hughes $8.0 million and $9.9 million during the three months ended January 31, 2021 and 2020 and $21.6 million and $30.6 million for the nine months ended January 31, 2021 and 2020, respectively. As of January 31, 2021 and April 30, 2020, accounts receivable, net included $1.0 million and $0.2 million and deferred revenue, current included $9.4 million and $1.5 million associated with Baker Hughes, respectively.

Summary of Business and Significant Accounting Policies (Policies)	9 Months Ended
	Jan. 31, 2021
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, or 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 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 final prospectus dated December 8, 2020, and filed with the SEC pursuant to Rule 424(b)(4) on December 9, 2020 (the “Final Prospectus”). 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 January 31, 2021, and the results of operations for the three and nine months ended January 31, 2021. The results of operations for the three and nine months ended January 31, 2021, 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 C3.ai, Inc. 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 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. Significant estimates include 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 value of common stock and 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 YearThe Company’s fiscal year ends on April 30.
Concentration of Risk	Concentration of Risk Financial instruments that potentially subject the Company to concentration of credit risk consist of cash and cash equivalents, investments and accounts receivable. The majority of the Company’s cash and cash equivalents are held by one financial institution. The Company is exposed to that financial institution to the extent that its cash balance with that financial institution is in excess of Federal Deposit Insurance Company, or FDIC, insurance limits. The Company’s investment policy is to invest in securities with a minimum rating of P1 by Moody’s, A1 by Standard & Poor’s, F-1 by Fitch’s or higher for short-term investments, and minimum rating of A2 by Moody’s, A by Standard & Poor’s, or A by Fitch’s or higher for long-term investments.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company currently qualifies as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Accordingly, the Company is provided the option to adopt new or revised accounting guidance either (1) within the same periods as those otherwise applicable to public business entities or (2) within the same time periods as private companies, including early adoption when permissible. The Company has elected to adopt new or revised accounting guidance within the same time period as private companies. Other than policies noted below, there have been no significant changes to the accounting policies disclosed in Note 1 of the audited consolidated financial statements as of and for the years ended April 30, 2020 and 2019 included in the Final Prospectus. Recently Adopted Accounting Standards—In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires a financial asset measured at amortized cost basis to be presented at the net amount expected to be collected. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. The guidance also limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and requires the reversal of previously recognized credit losses if fair value increases. The guidance is effective for the fiscal year beginning May 1, 2023 with early adoption permitted. The Company early adopted the guidance as of May 1, 2020 using a prospective transition method. Adoption of this guidance did not have a material impact to the Company’s consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2018-04 simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The guidance is effective for the fiscal year beginning May 1, 2023 with early adoption permitted. The Company early adopted the guidance as of May 1, 2020 using a prospective transition method. Adoption of this guidance did not have a material impact to the Company’s consolidated financial statements and related disclosures. In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815) I. Accounting for Certain Financial Instruments with Down Round Features II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. Part I of this standard applies to entities that issue financial instruments such as warrants, convertible debt or redeemable convertible preferred stock that contain down-round features. Part II of this standard replaces the indefinite deferral for certain mandatorily redeemable noncontrolling interests and mandatorily redeemable financial instruments of nonpublic entities contained within ASC Topic 480 with a scope exception and does not impact the accounting for these mandatorily redeemable instruments. The Company adopted the guidance as of May 1, 2020 using a prospective transition method. Adoption of this guidance did not have a material impact to the Company’s consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements with respect to Level 3 rollforwards, timing of liquidation of investments in certain entities that calculate net asset value, and measurement uncertainty. The Company adopted the guidance as of May 1, 2020 using a prospective transition method. Adoption of this guidance did not have a material impact to the Company’s consolidated financial statements and related disclosures. Recently Issued Accounting Standards Not Yet Adopted—In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to defer and recognize as an asset. The guidance is effective for the fiscal year beginning May 1, 2021. Early adoption is permitted. The Company is currently evaluating the effect that this guidance will have on the consolidated financial statements and related disclosures.
