Notes to Unaudited Condensed Consolidated Financial Statements

1. Overview and Basis of Presentation

Description of Business

Eventbrite, Inc. (Eventbrite or the Company) has built a powerful, broad technology platform to enable creators to solve the challenges associated with creating in-person and online live experiences. The Company’s platform integrates components needed to seamlessly plan, promote and produce live events. To further enhance the value of the creators’ self-service experience, the Company is working to reframe the Eventbrite product around the ongoing operational needs of creators in addition to the requirements of individual events. To this end, the Company has improved events calendaring, streamlined the event creation process and launched tools to assist creators in promoting multiple events and increasing audience size for their events.

Basis of Presentation

The accompanying condensed consolidated financial statements of the Company are unaudited. The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and the applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal and recurring nature considered necessary to state fairly the Company's consolidated financial position, results of operations and cash flows for the interim periods. All intercompany transactions and balances have been eliminated. The interim results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or for any other future annual or interim period.

The information included in this Quarterly Report on Form 10-Q should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Quantitative and Qualitative Disclosures About Market Risk" and the Consolidated Financial Statements and notes thereto included in Items 7, 7A and 8, respectively, in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 (2020 Form 10-K).

Revision of Condensed Consolidated Financial Statements

As disclosed in the 2020 Form 10-K, the Company identified an error within the condensed consolidated statement of cash flows for the nine months ended September 30, 2020. The accompanying financial statements have been revised to correct for such error. The impact of such revision resulted in net cash used in operating activities decreasing by $3.3 million to $124.0 million and net cash provided by financing activities decreasing by $3.3 million to $251.6 million for the nine months ended September 30, 2020. The Company evaluated the error and concluded that it was not material to the September 30, 2020 financial statements previously issued. These revisions have no impact on the Company's previously reported consolidated net income, financial position, net change in cash, cash equivalents, and restricted cash, or total cash, cash equivalents, and restricted cash as reported on the Company's consolidated statements of cash flows.

Use of Estimates

In order to conform with U.S. GAAP, the Company is required to make certain estimates, judgments and assumptions when preparing its consolidated financial statements. These estimates, judgments and assumptions affect the reported assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reported periods. These estimates include, but are not limited to, the recoverability of creator signing fees and creator advances, the chargebacks and refunds reserve, the capitalization and estimated useful life of internal-use software, certain assumptions used in the valuation of equity awards, assumptions used in determining the fair value of business combinations, the allowance for doubtful accounts, indirect tax reserves and contra-revenue amounts related to fraudulent events, customer disputed transactions and refunds. The Company evaluates these estimates on an ongoing basis. Actual results could differ from those estimates and such differences could be material to the Company’s consolidated financial statements.

COVID-19 Impacts

The Company continues to experience a significant impact due to the COVID-19 pandemic, the introduction and spread of new variants of the virus, including, for example, the Delta variant, and the social distancing and government mandates to restrict gatherings of people. The effect of and uncertainties surrounding the COVID-19 pandemic have caused the Company to make significant estimates in its unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2021, specifically related to chargebacks and refunds due to cancelled or postponed events, which impact net revenue, advance payouts, creator signing fees and creator advances.

The COVID-19 pandemic is ongoing in nature and the Company will continue to revise such estimates in future reporting periods to reflect management's best estimates of future outcomes. Significant uncertainty remains regarding the extent and duration of the impact that the COVID-19 pandemic will have on the Company’s business. The full extent to which COVID-19 impacts the Company’s business, results of operations and financial condition cannot be predicted at this time, and the impact of COVID-19 may persist for an extended period of time or become more pronounced.

Comprehensive Loss

For all periods presented, comprehensive loss equaled net loss. Therefore, the condensed consolidated statements of comprehensive loss have been omitted from the unaudited condensed consolidated financial statements.

Segment Information

The Company’s Chief Executive Officer (CEO) is the chief operating decision maker. The Company's CEO reviews discrete financial information presented on a consolidated basis for purposes of allocating resources and evaluating the Company’s financial performance. Accordingly, the Company has determined that it operates as a single operating segment and has one reporting unit.

2. Significant Accounting Policies

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Topic 470) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Topic 815), which eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation.

The Company early adopted ASU 2020-06 on January 1, 2021 using the modified retrospective transition method. Adoption of ASU 2020-06 resulted in a decrease to additional paid-in capital of $45.5 million, an increase to retained earnings of $3.1 million, and a net increase to long-term debt of $42.4 million. Refer to Note 8 – Debt for more details. The Company will use the if-converted method to calculate diluted EPS unless it makes an irrevocable election to settle the principal of the notes in cash and the excess conversion spread in shares, in which case the Company can continue to use the Treasury stock method. Since the Company had a net loss for the three and nine months ended September 30, 2021 and 2020, the convertible senior notes were determined to be anti-dilutive and therefore had no impact to basic or diluted net loss per share for the period as a result of adopting ASU 2020-06.

The Company's significant accounting policies are discussed in the "Notes to Consolidated Financial Statements, Note 2. Significant Accounting Policies" in the 2020 Form 10-K. There have been no significant changes to these policies that have had a material impact on the Company's unaudited condensed consolidated financial statements and related notes, except as noted above.

Revenue Recognition

The Company derives its revenues primarily from ticketing and payment processing. The Company also derives a smaller portion of revenues from marketing services. The Company's customers are event creators who use the Company's platform to sell tickets and market events to attendees. Revenue is recognized when or as control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services.

8

Transaction Revenue

For ticketing services, the Company's service provides a platform to the event creator and attendee to transact. The Company's performance obligation is to facilitate and process that transaction and issue the ticket, and revenue is recognized by the Company when the ticket is sold. The amount that the Company earns for its services is fixed which typically consists of a flat fee and a percentage based fee per ticket. As a result, the Company records revenue on a net basis related to its ticketing service fees.

For payment processing services, the Company's service provides the event creator with the choice of whether to use Eventbrite Payment Processing (EPP) or to use a third-party payment processor, referred to as Facilitated Payment Processing (FPP).

Under the EPP option, the Company is the merchant of record and is responsible for processing the transaction and collecting the face value of the ticket and all associated fees at the time the ticket is sold. The Company is also responsible for remitting these amounts collected, less the Company's fees, to the event creator. For EPP services, the Company determined that it is the principal in providing the service as the Company is responsible for fulfilling the promise to process the payment and has discretion in establishing the price of its service. As a result, the Company records revenue on a gross basis related to its EPP service fees. Costs incurred for processing the ticketing transactions are included in cost of net revenues in the consolidated statements of operations. Under the FPP option, the Company is not responsible for processing the transaction or collecting the face value of the ticket and associated fees. In this case, the Company records revenue on a net basis related to its FPP service fees.

Revenue is presented net of indirect taxes, customer refunds, payment chargebacks, estimated uncollectible amounts, creator royalties, and amortization of creator signing fees. Previously, the Company offered upfront payments to creators entering into new or renewed ticketing arrangements. However, the Company is shifting from upfront payment incentives to performance based incentives on a limited basis. See Note 4. Creator Signing Fees, Net, for further information relating to signing fees paid.

If an event is cancelled by a creator, then any obligations to provide refunds to event attendees are the responsibility of that creator. If a creator is unwilling or unable to fulfill their refund obligations, the Company may, at its discretion, provide attendee refunds.

Marketing Revenue

Revenue from marketing services is derived from providing creators with access to various marketing tools and functionalities for a monthly subscription fee. The Company considers that it satisfies its performance obligation as it provides the services to customers and recognizes revenue ratably over the service term which varies from one month to a year.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents includes bank deposits and money market funds held with financial institutions. Cash and cash equivalents balances include the face value of tickets sold on behalf of creators and their share of service charges, which are to be remitted to the creators. Such balances were $310.0 million and $181.1 million as of September 30, 2021 and December 31, 2020, respectively. Although creator cash is legally unrestricted, the Company does not utilize creator cash for its own financing or investing activities as the amounts are payable to creators on a regular basis. These amounts due to creators are included in accounts payable, creators on the consolidated balance sheets. The Company considers all highly liquid investments, including money market funds with an original maturity of three months or less at the date of purchase, to be cash equivalents.

The Company has issued letters of credit under lease agreements and other agreements which have been collateralized with cash. This cash is classified as noncurrent restricted cash on the consolidated balance sheets. The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same amounts shown in the consolidated statements of cash flows (in thousands):

	September 30, 2021		December 31, 2020
Cash and cash equivalents	$	667,868	$	505,756
Restricted cash	1,777		2,674
Total cash, cash equivalents and restricted cash	$	669,645	$	508,430

9

Funds Receivable

Funds receivable represents cash-in-transit from third-party payment processors that is received by the Company within approximately five business days from the date of the underlying ticketing transaction. The funds receivable balances include the face value of tickets sold on behalf of creators and their share of service charges, which amounts are to be remitted to the creators. Such amounts were $17.6 million and $10.0 million as of September 30, 2021 and December 31, 2020, respectively.

Accounts Payable, Creators

Accounts payable, creators consists of unremitted ticket sale proceeds, net of Eventbrite service fees and applicable taxes. Amounts are remitted to creators within five business days subsequent to the completion of the related event. Creators may apply to receive a portion of these proceeds prior to completion of their events. For qualified creators, the Company passes ticket sales proceeds to the creator prior to the event, subject to certain limitations. Internally, the Company refers to these payments as advance payouts. When an advance payout is made, the Company reduces its cash and cash equivalents with a corresponding decrease to its accounts payable, creators.

As a result of the COVID-19 pandemic and its effect of causing creators to cancel, postpone or reschedule events, the Company temporarily suspended its advance payouts program on March 11, 2020. The Company started making advance payouts available to a limited number of qualified creators during the third quarter of 2020. In the second quarter of 2021, the Company relaunched Scheduled Payouts (advance payouts) to paid creators who qualify and accept the Company's terms and conditions. As of September 30, 2021, advance payouts outstanding was approximately $300.0 million including $67.7 million of advance payouts issued since the third quarter of 2020, when the Company resumed the advance payout program on a limited basis.

Chargebacks and Refunds Reserve

The terms of the Company's standard merchant agreement obligate creators to reimburse attendees who are entitled to refunds. When the Company provides advance payouts, it assumes risk that the event may be cancelled, fraudulent or materially not as described, resulting in significant chargebacks and refund requests. If the creator is insolvent or has spent the proceeds of the ticket sales for event-related costs, the Company may not be able to recover its losses from these events, and such unrecoverable amounts could equal the value of the transaction or transactions settled to the creator prior to the event that is disputed, plus any associated chargeback fees not assumed by the creator. The Company records estimates for refunds and chargebacks of its fees as contra-revenue. The Company records estimates for losses related to chargebacks and refunds of the face value of tickets as an operating expense classified within sales, marketing and support. Reserves are recorded based on the Company's assessment of various factors, including the amounts paid and outstanding to creators in conjunction with the advance payout program, the size and nature of future events, the remaining time to event date, and actual chargeback and refund activity during the current year.

Impairment of Long-lived Assets

The carrying amounts of long-lived assets, including property and equipment, capitalized internal-use software, acquired intangible assets and right-of-use operating lease assets are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful life is shorter than originally estimated. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to future undiscounted net cash flows the asset is expected to generate over its remaining life.

If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the revised shorter useful life.

Significant judgment and estimates are required in assessing impairment of long-lived assets, including identifying whether events or changes in circumstances require an impairment assessment, estimating future cash flows, and determining appropriate discount rates. As of September 30, 2021, management did not identify any events or changes in circumstances that would require an impairment assessment.

10

Fair Value Measurement

The Company measures its financial assets and liabilities at fair value at each reporting date using a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value:

Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 – Other inputs that are directly or indirectly observable in the marketplace.

Level 3 – Unobservable inputs that are supported by little or no market activity.

The Company’s cash equivalents, funds receivable, accounts receivable, accounts payable, funds payable and other current liabilities approximate their fair value. All such financial assets and liabilities are Level 1 and are measured at fair value on a recurring basis. There were no other Level 1 assets or liabilities recorded at September 30, 2021 and December 31, 2020.

Refer to Note 8 “Debt” for details regarding the fair value of our convertible senior notes.

3. Accounts Receivable, Net

Accounts receivable, net is comprised of invoiced amounts to customers who use FPP for payment processing as well as other invoiced amounts. In evaluating the Company’s ability to collect outstanding receivable balances, the Company considers various factors including the age of the balance, the creditworthiness of the customer and the customer’s current financial condition. Accounts receivable deemed uncollectible are charged against the allowance for doubtful accounts when identified. The following table summarizes the Company’s accounts receivable balances as of the dates indicated (in thousands):

	September 30, 2021		December 31, 2020
Accounts receivable, customers	$	2,328	$	1,494
Allowance for doubtful accounts	(967)		(1,036)
Accounts receivable, net	$	1,361	$	458

4. Creator Signing Fees, Net

Creator signing fees are incentives that are offered and paid by the Company to secure exclusive ticketing and payment processing rights with certain creators. The benefit the Company receives by securing exclusive ticketing and payment processing rights with certain creators from creator signing fees is inseparable from the customer relationship with the creator and accordingly these fees are recorded as a reduction of revenue in the consolidated statements of operations.

As of September 30, 2021, the balance of creator signing fees, net is being amortized over a weighted-average remaining contract life of 3.2 years on a straight-line basis. The following table summarizes the activity in creator signing fees for the periods indicated (in thousands):

Creator signing fees, noncurrent	2,617		8,669
Total creator signing fees	$	4,356	$	13,774

5. Creator Advances, Net

Creator advances are incentives that are offered by the Company which provide the creator with funds in advance of the event. These are subsequently recovered by withholding amounts due to the Company from the sale of tickets for the event until the creator payment has been fully recovered.

The following table summarizes the activity in creator advances for the periods indicated (in thousands):

	Three Months Ended September 30,

Amortization of capitalized internal-use software development costs	1,235		1,885		4,555		6,092

7. Leases

Operating Leases

The Company has operating leases primarily for office space. The Company subleases certain leased office space to third parties when it determines there is excess leased capacity. Operating lease right-of-use assets and operating lease liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term. Right-of-use assets also include adjustments related to prepaid or deferred lease payments and lease incentives. In calculating the present value of the lease payments, the Company utilizes its incremental borrowing rate, as the rates implicit in the leases were not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located.

The components of operating lease costs were as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Operating lease costs	$	646	$	1,977	$	3,830	$	5,872
Sublease income	(57)		(1,082)		(1,372)		(3,124)
Total operating lease costs, net	$	589	$	895	$	2,458	$	2,748

As of September 30, 2021, the Company's operating leases had a weighted-average remaining lease term of 4.1 years and a weighted-average discount rate of 3.2%. Operating lease right-of-use assets obtained in exchange for operating lease obligations were $0.2 million and $2.3 million in the nine months ended September 30, 2021 and 2020 respectively.

13

In August 2021, the Company entered into a lease agreement for an office facility in San Francisco, California for which the lease term commenced on October 1, 2021 and will expire on September 29, 2023.

8. Debt

The Company adopted ASU 2020-06, effective January 1, 2021 which resulted in decreased non-cash interest expense on the 5.000% convertible senior notes due 2025 (the 2025 Notes) due to the elimination of the discount associated with the equity component.

As of September 30, 2021, long-term debt consisted of the following (in thousands):

	Convertible Notes (2026 Notes)		Convertible Notes (2025 Notes)		Total
Outstanding principal balance	$	212,750	$	150,000	$	362,750

Term Loans

On March 11, 2021, the Company repaid all borrowings outstanding under the Credit Agreement, dated as of May 9, 2020 (and as amended on June 15, 2020), by and among the Company, FP EB Aggregator, L.P. (FP) and Wilmington Trust, National Association, as the administrative agent (the May 2020 credit agreement), and subsequently terminated the May 2020 credit agreement. In connection with the early termination of the borrowings outstanding under the May 2020 credit agreement, the Company paid $153.2 million, which consisted of $125.0 million in principal payments, a $18.2 million make-whole premium, $9.0 million payment in kind interest and $1.0 million of accrued cash interest.

In May 2020, in connection with the execution of the May 2020 credit agreement, the Company entered into a stock purchase agreement with FP to issue and sell 2,599,174 shares of Class A Common Stock to FP for a purchase price of $0.01 per share. The Company accounted for these shares at fair value and recorded $27.4 million as debt discount. The Company incurred total cash costs of $13.2 million, of which $7.6 million were third party offering costs and the remaining $5.6 million were lender fees, resulting in total debt issuance costs and discount of $40.6 million.

The Company recorded a loss on debt extinguishment of $50.0 million during nine months ended September 30, 2021. The loss primarily related to the write-off of unamortized debt discount and issuance costs of $31.8 million and a $18.2 million make-whole premium.

During the nine months ended September 30, 2021, the Company recorded $2.2 million payment in kind interest, $2.2 million amortization of debt discount and issuance costs, and $1.0 million cash interest. During the nine months ended September 30, 2020, the Company recorded $4.0 million payment in kind interest, $3.9 million amortization of debt discount and issuance costs, and $1.9 million cash interest.

Senior Notes

2025 Notes

In June 2020, the Company issued $150.0 million aggregate principal amount of 5.000% convertible senior notes due 2025 (the 2025 Notes), in a private offering to qualified institutional buyers. Interest is payable in cash semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020. The 2025 Notes mature on December 1, 2025, unless earlier repurchased, redeemed or converted. The total net proceeds from the 2025 Notes, after deducting the debt issuance costs of $5.7 million, was $144.3 million.

Prior to the adoption of ASU 2020-06, the Company separated the conversion option of the 2025 Notes from the debt instrument and classified the conversion option in equity. The 2025 Notes were not issued at a substantial premium. ASU 2020-06 eliminates the cash conversion model in ASC 470-20, no longer requiring the Company to account for the embedded conversion feature as a component of equity. As a result, the Company now accounts for the 2025 Notes as a single unit of account.

The adoption of ASU 2020-06 primarily had the following impact on the Company's financial statements:

•Recognition of additional $45.5 million in long term debt on the consolidated balance sheet as of January 1, 2021. This relates to the derecognition of the conversion option which was previously classified as equity.

•A cumulative effect adjustment was recognized to the opening balance of retained earnings of $3.1 million. This relates to the decreased interest expense on the 2025 Notes for fiscal 2020 due to the elimination of the discount resulting from the recognition of the equity component.

•The deferred taxes previously recognized upon the issuance of the 2025 Notes were reversed upon the adoption of ASU 2020-06 through equity and were offset by a valuation allowance, resulting in no income tax impact to the consolidated financial statements.

The effective interest rate of the 2025 Notes is 5.8%. During the nine months ended September 30, 2021, the Company recorded cash interest of $5.6 million, and amortization of debt issuance costs of $0.7 million. During the nine months ended September 30, 2020, the Company recorded cash interest of $2.2 million, and amortization of debt discount and issuance costs of $1.9 million.

The 2025 Notes are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the 2025 Notes; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries.

The terms of the 2025 Notes are governed by an Indenture by and between the Company and Wilmington Trust, National Association, as Trustee (the Indenture). The Company may irrevocably elect a settlement in cash, shares of Class A common stock, or a combination of cash and shares of Class A common stock.

The 2025 Notes are convertible at an initial conversion rate of 79.3903 shares of Class A common stock per $1,000 principal amount of 2025 Notes, which is equal to an initial conversion price of approximately $12.60 per share of Class A common stock. The conversion rate is subject to adjustment under certain circumstances in accordance with the terms of the Indenture. Holders of the 2025 Notes may convert all or a portion of their 2025 Notes only in multiples of $1,000 principal amount, under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the last reported sale price per share of our Class A common stock exceeds 130% of the conversion price of the 2025 Notes for each of the at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter;

•during the five consecutive business days immediately after any 10 consecutive trading day period in which the trading price per $1,000 principal amount of 2025 Notes for each trading day of that 10 consecutive trading day period was less than 98% of the product of the last reported sale price of Class A common stock and the conversion rate on such trading day;

•upon the occurrence of certain corporate events or distributions on the Company's Class A common stock, as described in the Indenture;

16

•if the Company calls the 2025 Notes for redemption; or

•at any time from, and including, June 2, 2025 until the close of business on the second scheduled trading day immediately before the maturity date.

Holders of the 2025 Notes who convert their 2025 Notes in connection with certain corporate events that constitute a make-whole fundamental change (as defined in the Indenture) are, under certain circumstances, entitled to an increase in the conversion rate.

No sinking fund is provided for the 2025 Notes. The 2025 Notes are redeemable, in whole or in part, at the Company's option at any time and from time to time, on or after June 1, 2023 and on or before the 40th scheduled trading day immediately prior to the maturity date, at a cash redemption price equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of Class A common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading dates ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such notice. Additionally, calling any of the 2025 Notes for redemption will constitute a make-whole fundamental change with respect to that portion of the 2025 Notes, in which case the conversion rate applicable to the conversion of those 2025 Notes will be increased in certain circumstances (as described in the Indenture) if it is converted after it is called for redemption.

If certain corporate events that constitute a “Fundamental Change” (as defined in the Indenture) occur, then, subject to a limited exception for certain cash mergers, note holders may require the Company to repurchase their 2025 Notes at a cash repurchase price equal to the principal amount of the 2025 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change repurchase date. The definition of Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s Class A common stock.

The 2025 Notes have customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), which include the following: (i) certain payment defaults on the 2025 Notes; (ii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iii) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person; (iv) a default by the Company in its other obligations or agreements under the Indenture or the 2025 Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; (v) the rendering of certain judgments against the Company or any of its subsidiaries for the payment of at least $10,000,000, where such judgments are not discharged or stayed within 45 days after the date on which the right to appeal has expired or on which all rights to appeal have been extinguished; (vi) certain defaults by the Company or any of its significant subsidiaries with respect to indebtedness for borrowed money of at least $10,000,000; and (vii) certain events of bankruptcy, insolvency and reorganization involving the Company or any of the Company’s significant subsidiaries.

If an Event of Default involving bankruptcy, insolvency or reorganization events with respect to the Company (and not solely with respect to a significant subsidiary of the Company) occurs, then the principal amount of, and all accrued and unpaid interest on, all of the 2025 Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other Event of Default occurs and is continuing, then, the Trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of 2025 Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the 2025 Notes then outstanding to become due and payable immediately. However, notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an Event of Default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on the 2025 Notes for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the 2025 Notes.

The fair value of the 2025 Notes, which we have classified as a Level 2 instrument, was $260.2 million as of September 30, 2021. The fair value of the 2025 Notes is determined using observable market prices on the last business day of the period.

2026 Notes

In March 2021, the Company issued $212.75 million aggregate principal amount of 0.750% convertible senior notes due 2026 (the 2026 Notes) in a private offering to qualified institutional buyers, inclusive of the initial purchaser's exercise in full of its option to purchase additional notes. The 2026 Notes bear interest at a fixed rate of 0.750% per year. Interest is payable in cash semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2021. The 2026 Notes mature on September 15, 2026 unless earlier repurchased, redeemed or converted. The total net proceeds from the 2026 Notes, after deducting debt issuance costs of $5.7 million, was $207.0 million.

The 2026 Notes are the Company’s senior, unsecured obligations and are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the 2026 Notes and effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iii) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries.

Before March 15, 2026, noteholders will have the right to convert their 2026 Notes under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price per share of our Class A common stock exceeds 130% of the conversion price for each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter;

•during the five consecutive business days immediately after any 10 consecutive trading day period in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of our Class A common stock on such trading day and the conversion rate on such trading day;

•upon the occurrence of certain corporate events or distributions on our Class A common stock, as described in the Indenture and

•if the Company call such notes for redemption;

From and after March 15, 2026, noteholders may convert their 2026 Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. Upon conversion, the 2026 Notes may be settled in cash, shares of Class A common stock, or a combination of cash and shares of Class A common stock, at the Company's election. The Company may irrevocably elect a settlement in cash, shares of Class A common stock, or a combination of cash and shares of Class A common stock.

The 2026 Notes are convertible at an initial conversion rate of 35.8616 shares of Class A common stock per $1,000 principal amount of 2026 Notes, which is equal to an initial conversion price of approximately $27.89 per share of Class A common stock. The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events. In addition, if certain corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time.

No sinking fund is provided for the 2026 Notes. The 2026 Notes will be redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after March 15, 2024 and on or before the 40th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid interest, if any, but only if the last reported sale price per share of the Company’s Class A common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such notice. In addition, calling any 2026 Note for redemption will constitute a Make-Whole Fundamental Change with respect to that Note, in which case the conversion rate applicable to the conversion of that 2026 Note will be increased in certain circumstances if it is converted after it is called for redemption.

If certain corporate events that constitute a “Fundamental Change” (as defined in the Indenture) occur, then, subject to a limited exception for certain cash mergers, noteholders may require the Company to repurchase their 2026 Notes at a cash repurchase price equal to the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid interest, if any. The definition of Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s Class A common stock.

18

The 2026 Notes have customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), which include the following: (i) certain payment defaults on the Notes (which, in the case of a default in the payment of interest on the Notes, will be subject to a 30-day cure period); (ii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iii) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person; (iv) a default by the Company in its other obligations or agreements under the Indenture or the Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; (v) certain defaults by the Company or any of its significant subsidiaries with respect to indebtedness for borrowed money of at least $10,000,000; and (vi) certain events of bankruptcy, insolvency and reorganization involving the Company or any of the Company’s significant

subsidiaries.

If an Event of Default involving bankruptcy, insolvency or reorganization events with respect to the Company (and not solely with respect to a significant subsidiary of the Company) occurs, then the principal amount of, and all accrued and unpaid interest on, all of the 2026 Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other Event of Default occurs and is continuing, then the Trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the 2026 Notes then outstanding to become due and payable immediately. However, notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an Event of Default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on the 2026 Notes for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the 2026 Notes.

In accounting for the issuance of the 2026 Notes, total issuance costs of $5.7 million related to the 2026 Notes are being amortized to interest expense over the term of the 2026 Notes using the effective interest rate method.

The effective interest rate of the 2026 Notes is 1.3%. During the nine months ended September 30, 2021, the Company recorded cash interest of $0.9 million, and amortization of debt issuance costs of $0.6 million.

The fair value of the 2026 Notes, which we have classified as a Level 2 instrument, was $209.3 million as of September 30, 2021. The fair value of the 2026 Notes is determined using observable market prices on the last business day of the period.

Capped Call Transactions

In March 2021, in connection with the offering of the 2026 Notes, the Company entered into privately negotiated capped call transactions (2026 Capped Calls) with certain financial institutions (2026 Option Counterparties). The 2026 Capped Calls cover, subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the 2026 Notes, the number of shares of Class A common stock initially underlying the 2026 Notes. The 2026 Capped Calls are expected generally to reduce potential dilution to the Class A common stock upon any conversion of 2026 Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of such converted 2026 Notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the 2026 Capped Calls will initially be $37.5375 per share of Class A common stock, and is subject to certain customary adjustments under the terms of the 2026 Capped Calls. The 2026 Capped Calls will expire in September 2026, if not exercised earlier.

The 2026 Capped Calls are separate transactions entered into by the Company with each 2026 Option Counterparty, and are not part of the terms of the 2026 Notes and will not affect any noteholder’s rights under the 2026 Notes. Noteholders will not have any rights with respect to the 2026 Capped Calls.

The 2026 Capped Calls are subject to adjustment upon the occurrence of specified extraordinary events affecting the company, including merger events, tender offers and announcement events. In addition, the 2026 Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the 2026 Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings and hedging disruptions.

The 2026 Capped Call Transactions do not meet the criteria for separate accounting as a derivative. The aggregate premium paid for the purchase of the 2026 Capped Calls of $18.5 million was recorded as a reduction to additional paid-in capital on the consolidated balance sheets.

In June 2020, in connection with the offering of the 2025 Notes, the Company entered privately negotiated capped call transactions with certain financial institutions (2025 Capped Calls). The 2025 Capped Calls have an initial strike price of approximately $12.60 per share, which corresponds to the initial conversion price of the 2025 Notes. The 2025 Capped Calls

19

cover, subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the 2025 Notes, the number of shares of Class A common stock initially underlying the 2025 Notes. The 2025 Capped Calls are expected generally to reduce potential dilution to the Company’s Class A common stock upon any conversion of the 2025 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2025 Notes, as the case may be, with such reduction and/or offset subject to a cap, initially equal to $17.1520, and is subject to certain adjustments under the terms of the 2025 Capped Call transactions. The 2025 Capped Calls will expire in December 2025, if not exercised earlier.

The 2025 Capped Calls are subject to adjustment upon the occurrence of specified extraordinary events affecting the company, including merger events, tender offers and announcement events. In addition, the 2025 Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the 2025 Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings and hedging disruptions. For accounting purposes, the 2025 Capped Calls are separate transactions, and not part of the terms of the Notes.

The 2025 Capped Call Transactions do not meet the criteria for separate accounting as a derivative. The aggregate premium paid for the purchase of the 2025 Capped Calls of $15.6 million was recorded as a reduction to additional paid-in capital on the consolidated balance sheets.

9. Goodwill and Acquired Intangible Assets, Net

The carrying amounts of the Company's goodwill was $174.4 million as of September 30, 2021 and December 31, 2020.

The Company tests goodwill for impairment at least annually, in the fourth quarter, or whenever events or changes in circumstances would more likely than not reduce the fair value of its single reporting unit below its carrying value. As a result of a qualitative assessment, management concluded goodwill was not impaired as of September 30, 2021, and does not believe that its reporting unit is at risk of failing the impairment test since the fair value of the reporting unit substantially exceeded the carrying value.

Acquired intangible assets consisted of the following (in thousands):

10. Commitments and Contingencies

The Company's principal commitments consist of obligations under the 2025 Notes and 2026 Notes (including principal and coupon interest), operating leases for office space, future creator signing fees and creator advances, as well as non-cancellable purchase commitments.

During the nine months ended September 30, 2021, the Company issued the 2026 Notes, which consisted of $212.75 million aggregate principal amount of 0.750% convertible senior notes due 2026 in a private offering. As of September 30, 2021, the Company's contractual obligation to settle commitments related to the principal amount of 2026 Notes is $212.75 million for the year ended December 31, 2026. The Company also entered into a lease arrangement in August 2021. The cumulative obligations payable by the Company over the term of the lease total $1.6 million. Other than as described above, there were no material changes outside the Company's normal course of business in its commitments under contractual obligations from those disclosed in the 2020 Form 10-K.

The following table summarizes the Company's contractual obligation to settle commitments related to the 2026 Notes and 2025 Notes as of September 30, 2021 (in thousands):

	Payments due by Year

Litigation and Loss Contingencies

In addition to the litigation discussed below, from time to time, the Company may become a party to litigation and subject to claims incident to the ordinary course of business, including intellectual property claims, labor and employment claims, breach of contract claims, tax and other matters. Future litigation may be necessary to defend the Company or its creators.

The results of any current or future 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.

The Company accrues estimates for resolution of legal and other contingencies when losses are probable and estimable. The Company's assessment of losses is re-evaluated each accounting period and is based on all available information, including impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to each case. Nevertheless, it is possible that additional future legal costs including settlements, judgments, legal fees and other related defense costs could have a material adverse effect on the Company’s business, consolidated financial position, results of operations or liquidity.

The matters discussed below summarize the Company’s current ongoing pending litigation.

Refund Policy Litigation

On June 4, 2020, three plaintiffs, seeking to represent a proposed class of individuals who purchased tickets on or after June 3, 2016, filed suit against the Company in the United States District Court for the Northern District of California, in a case captioned Snow, et al. v. Eventbrite, Inc., Case No. 20-cv-03698 (the Class Action). Plaintiffs allege that Eventbrite failed to provide an opportunity for purchasers of tickets to events sold through Eventbrite’s platform to obtain a refund where the event is postponed, rescheduled, or canceled. Plaintiffs seek injunctive relief in addition to restitution and monetary damages under California’s Consumer Legal Remedies Act, False Advertising Law, and Unfair Competition Law, in addition to claims brought under California common law. The Company denies the allegations and intends to defend the case vigorously. The case is in its early stages. Prior to answering Plaintiffs’ complaint, Eventbrite brought a motion to compel arbitration pursuant to its Terms of Service. The Court denied that motion. The Company thereafter answered Plaintiffs’ Complaint and brought a second motion to compel arbitration, based in part on facts established via the Company’s Answer. The Court granted that motion on September 2, 2021, and stayed the suit pending the results of arbitration. Two of the named Plaintiffs have since initiated individual arbitrations pursuant to the Company’s Terms of Service. The Company has not yet filed any response or other paper in either proceeding. The Company is unable to predict the likely outcome at this point.

Securities Litigation

Beginning on April 15, 2019, purported stockholders of the Company filed two putative securities class action complaints in the United States District Court for the Northern District of California, and three putative securities class action complaints in the Superior Court of California for the County of San Mateo, against the Company, certain of its executives and directors, and its underwriters for the Company's initial public offering (IPO). Some of these actions also name as defendants venture capital firms that were investors in the Company as of the IPO.

On August 22, 2019, the federal court consolidated the two pending actions (the Federal Action). On October 11, 2019, the lead plaintiffs in the Federal Action filed an amended consolidated complaint. That complaint alleged that the Company misrepresented and/or omitted material information in its IPO offering documents in violation of the Securities Act. It also challenged public statements made after the IPO in violation of the Exchange Act. The amended complaint sought unspecified monetary damages and other relief on behalf of investors. On December 11, 2019, the defendants filed a motion to dismiss the amended complaint. On April 28, 2020, the court granted defendants’ motion to dismiss in its entirety with leave to amend and set a deadline of June 24, 2020 for lead plaintiff to file its second amended consolidated complaint. On June 22, 2020, the Court extended lead plaintiff’s deadline to file its second amended consolidated complaint to August 10, 2020.

On July 29, 2020, the Company entered into a settlement agreement with the lead plaintiff in the Federal Action. On August 27, 2020, the lead plaintiff in the Federal Action filed a motion for preliminary approval of the settlement. On October 21, 2020, the Court vacated the preliminary approval hearing, and on October 30, 2020, the Court issued an order continuing the preliminary approval hearing, tentatively rescheduling the hearing for March 18, 2021. On January 22, 2021, the Court issued an order denying without prejudice the motion for preliminary approval. On February 9, 2021, the Company gave notice to the lead plaintiff that, in light of the denial of the preliminary approval motion, it was terminating the settlement agreement.

On June 24, 2019, the state court consolidated two state actions pending at that time (the State Action). On July 24, 2019, the two plaintiffs in the State Action filed a consolidated complaint. The consolidated complaint generally alleged that the Company misrepresented and/or omitted material information in the IPO offering documents, in violation of the Securities Act, and sought unspecified monetary damages and other relief on behalf of investors. On August 23, 2019, defendants filed demurrers to the consolidated complaint, which the court sustained with leave to amend at a hearing on November 1, 2019. Plaintiffs filed a first amended consolidated complaint (FAC) on February 10, 2020. Defendants filed demurrers to the FAC on March 26, 2020. On June 23, 2020, the court sustained the demurrers with leave to amend. On November 9, 2020, the plaintiffs filed their second amended consolidated complaint (SAC). On November 20, 2020, defendants filed demurrers to the SAC, which were overruled on December 17, 2020. On January 15, 2021, defendants filed their answers to the SAC. On January 22, 2021, the plaintiffs filed a motion for class certification. On February 11, 2021, the parties stipulated to class certification, and on February 17, 2021, the Court entered an order certifying a class of “all persons and entities who purchased or otherwise acquired Eventbrite, Inc. Class A common stock pursuant or traceable to the Registration Statement and Prospectus issued in connection with Eventbrite’s September 2018 Initial Public Offering and who were damaged thereby.”

22

On October 26, 2021, the Company entered into a binding settlement agreement with the two plaintiffs in the State Action described above. In connection with the settlement, the Company and its insurers have agreed to pay $19.25 million. Accordingly, during the three months ended September 30, 2021, the Company increased its estimated liability recorded related to the securities litigation described above from $7.5 million to $19.25 million, which amount was included in "other accrued liabilities" in the accompanying condensed consolidated balance sheets as of September 30, 2021. Under the terms of the proposed settlement, which shall be paid by the Company and its insurers, the Company expects a contribution to be made by its insurers of approximately $12.5 million, which amount was included in "prepaid expenses and other current assets" in the accompanying condensed consolidated balance sheets as of September 30, 2021. The insurance contribution of approximately $12.5 million is recorded as a reduction to general and administrative expense during the three months ended September 30, 2021. The increase in estimated liability of $11.8 million is recorded as an increase to general and administrative expense during the three months ended September 30, 2021.

The proposed settlement “Class” is defined as “all persons and entities who purchased or otherwise acquired Class A common shares of Eventbrite between September 20, 2018, and May 24, 2019, inclusive,” excluding the defendants and other “Excluded Persons” defined in the settlement agreement. If the settlement is approved by the court in the State Action, any settlement “Class Member” that does not request exclusion from the proposed settlement “Class” will fully, finally, and forever release “any and all rights, liabilities, suits, debts, obligations, demands, damages, losses, judgment matters, issues, claims . . . and causes of action of every nature and description whatsoever that have been or could have been asserted in the [State] Action or the Federal Action or could in the future be asserted in any forum . . . whether individual, class, representative, on behalf of others, legal, equitable, regulatory, governmental, or of any other type or in any other capacity, whether brought directly or indirectly against any of the Defendants, that (i) arise out of, are based upon, or relate to in any way to any of the allegations, acts, transactions, facts, events, matters, occurrences, representations, or omissions which were or could have been alleged in the [State] Action or the Federal Action, and (ii) arise out of, are based upon, or relate to in any way to the purchase, acquisition, holding, sale, or disposition of Eventbrite Class A common stock between September 20, 2018 and May 24, 2019, inclusive.”

As of this filing, the plaintiffs in the State Action have not yet filed a motion for preliminary approval of the proposed settlement. Final approval of the settlement is subject to a number of conditions and contingencies outside of the Company’s control. There can be no guarantee that all of those conditions and contingencies to final approval of the settlement will occur. Should a material condition or contingency to the settlement fail to occur, one or both of the parties to the settlement may exercise their right to terminate the settlement agreement.

Commercial Contract Litigation

On June 18, 2020, the Company filed a Complaint in the United States District Court for the Northern District of California against M.R.G. Concerts Ltd. (MRG) and Matthew Gibbons (Gibbons), asserting claims for breach of contract, breach of the implied covenant of good faith and fair dealing, declaratory judgment, unfair competition, and common counts under California law, arising out of MRG and Gibbons’s termination of certain contracts with the Company and their refusal to make various payments to the Company required by those contracts. MRG asserted counterclaims against the Company for breach of one of the contracts in issue, as well as for breach of the implied covenant of good faith and fair dealing, unfair competition, and declaratory judgment. On October 1, 2020, the Company moved to dismiss MRG’s counterclaims and certain of MRG and Gibbons’s affirmative defenses. The Court denied Eventbrite’s motion. Fact discovery and expert discovery have closed. The Company has filed motions for summary judgment in its favor, and to exclude Defendants’ proffered expert testimony. Those motions remain pending. The Company cannot presently predict the likelihood of success.

Tax Matters

The Company is currently under audit in certain jurisdictions with regard to indirect tax matters. The Company establishes reserves for indirect tax matters when it determines that the likelihood of a loss is probable, and the loss is reasonably estimable. Accordingly, the Company has established a reserve for the potential settlement of issues related to sales and other indirect taxes in the amount of $10.1 million and $13.6 million as of September 30, 2021 and December 31, 2020, respectively. These amounts, which represent management’s best estimates of its potential liability, include potential interest and penalties of $1.5 million as of September 30, 2021 and December 31, 2020.

The Company does not believe that any ultimate liability resulting from any of these matters will have a material adverse effect on its business, consolidated financial position, results of operations or liquidity. However, the outcome of these matters is inherently uncertain. Therefore, if one or more of these matters were resolved against the Company for amounts in excess of management’s expectations, the Company’s financial statements, including in a particular reporting period in which any such outcome becomes probable and estimable, could be materially adversely affected.

23

Indemnification

In the ordinary course of business, the Company enters into contractual arrangements under which the Company agrees to provide indemnification of varying scope and terms to business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of the breach of such agreements, intellectual property infringement claims made by third parties, and other liabilities relating to or arising from the Company’s online ticketing platform or the Company’s acts or omissions. In these circumstances, payment may be conditional on the other party making a claim pursuant to the procedures specified in the particular contract. Further, the Company’s obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments. In addition, the Company has indemnification agreements with its directors and executive officers that require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The terms of such obligations vary.

11. Stockholders' Equity

Equity Incentive Plans

In August 2018, the 2018 Stock Option and Incentive Plan (2018 Plan) was adopted by the board of directors and approved by the stockholders and became effective in connection with the IPO. The 2018 Plan replaced the 2010 Stock Plan (2010 Plan) as the board of directors determined not to make additional awards under the 2010 Plan. The 2010 Plan will continue to govern outstanding equity awards granted thereunder.

The 2018 Plan allows for the granting of options, stock appreciation rights, restricted stock, restricted stock units (RSUs), unrestricted stock awards, dividend equivalent rights and cash-based awards. Every January 1, the number of shares of stock reserved and available for issuance under the 2018 Plan will cumulatively increase by five percent of the number of shares of Class A and Class B common stock outstanding on the immediately preceding December 31, or a lesser number of shares as approved by the board of directors.

As of September 30, 2021, there were 8,306,321 and 4,998,430 options issued and outstanding under the 2010 Plan and 2018 Plan, respectively (collectively, the Plans), and 8,614,869 shares of Class A common stock were available for grant under the 2018 Plan.

Stock options granted typically vest over a four-year period from the date of grant. Options awarded under the Plans may be granted at an exercise price per share not less than the fair value at the date of grant and are exercisable up to ten years.

Stock Option Activity

Stock option activity for the nine months ended September 30, 2021 is presented below:

	Outstanding options	Weighted average exercise price	Weighted average remaining contractual term (years)	Aggregate intrinsic value (thousands)
Balance as of December 31, 2020	13,675,252	9.82	6.4	113,499
Granted	1,050,665	20.70
Exercised	(1,351,671)	7.58
Cancelled	(69,495)	10.82
Balance at September 30, 2021	13,304,751	10.90	6.2	109,135
Vested and exercisable as of September 30, 2021	9,469,551	9.68	5.2	87,852
Vested and expected to vest as of September 30, 2021	13,097,227	10.85	6.1	107,956

The aggregate intrinsic value in the table above represents the difference between the fair value of common stock and the exercise price of outstanding, in-the-money stock options at September 30, 2021.

As of September 30, 2021, the total unrecognized stock-based compensation expense related to stock options outstanding was $27.1 million, which will be recognized over a weighted-average period of 2.4 years. The weighted-average fair value of stock options granted was $11.87 for the nine months ended September 30, 2021.

24

Restricted Stock Units Activity

Restricted stock activity for the nine months ended September 30, 2021 is presented below:

	Outstanding RSUs and RSAs	Weighted-average grant date fair value per share	Weighted average remaining contractual term (years)	Aggregate intrinsic value (thousands)
Balance at December 31, 2020	3,765,926	14.16	1.4	68,164
Awarded	2,977,947	20.81
Released	(1,336,872)	14.36

Balance at September 30, 2021	4,800,998	17.91	1.5	90,750
Vested and expected to vest as of September 30, 2021	4,176,550	17.78	1.4	78,979

As of September 30, 2021, the total unrecognized stock-based compensation expense related to RSUs outstanding was $66.3 million, which will be recognized over a weighted-average period of 2.9 years.

Stock-based Compensation Expense

Stock-based compensation expense recognized in connection with stock options, RSUs and the employee stock purchase plan during the three and nine months ended September 30, 2021 and 2020 were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Cost of net revenue	$	197	$	260	$	735	$	890
Product development	4,258		3,101		12,515		10,156
Sales, marketing and support	1,426		1,281		4,160		3,613
General and administrative	6,419		5,465		18,575		15,882
Total	$	12,300	$	10,107	$	35,985	$	30,541

The Company capitalized $0.2 million and $0.4 million of share-based compensation expense related to capitalized software costs during the three and nine months ended September 30, 2021, respectively, compared to $0.5 million and $1.0 million during the three and nine months ended September 30, 2020 respectively.

12. Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potentially dilutive securities outstanding for the period. As the Company had net losses for the quarters ended September 30, 2021 and 2020, all potentially issuable shares of common stock were determined to be anti-dilutive.

The following table sets forth the computation of basic and diluted net loss per share (in thousands, except per share data):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020			2021		2020
Net loss	$	(16,813)	$	(19,427)		$	(122,244)	$	(204,487)
Weighted-average shares used in computing net loss per share, basic and diluted	94,462		90,973			93,794		88,441
Net loss per share, basic and diluted	$	(0.18)	$	(0.21)		$	(1.30)	$	(2.31)

25

The following outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share because including them would have had an anti-dilutive effect (in thousands):

	September 30, 2021	September 30, 2020
Stock-options to purchase common stock	13,305	14,493
Shares related to convertible senior notes	19,538	11,909
Restricted stock units	4,767	4,141
ESPP	52	—
Total shares of potentially dilutive securities	37,662	30,543

Prior to January 1, 2021, the Company used the treasury stock method for calculating any potential dilutive effect of the conversion spread on net loss per share, if applicable. After the adoption of ASU 2020-06, the Company used the if-converted method for calculating any potential dilutive effect of its convertible senior notes for the three and nine months ended September 30, 2021. The potential impact upon the conversion of the convertible senior notes were excluded from the calculation of diluted net loss per share for the three and nine months ended September 30, 2021 because their effect would have been anti-dilutive.

For the 2026 Notes, the conversion spread of 7.6 million shares will have a dilutive impact on diluted net income per share of common stock when the average market price of the Company’s Class A common stock for a given period exceeds the conversion price of $27.89 per share. Although the average market price of the Company's Class A common stock exceeds the conversion price of $12.60 per share for the 2025 Notes, the conversion spread of 11.9 million shares did not impact the net loss per share calculation as it would have an anti-dilutive effect.

13. Income Taxes

The Company recorded income tax expense of $0.3 million and $0.9 million for the three and nine months ended September 30, 2021, respectively, compared to income tax expense of $0.2 million and $0.3 million for the three and nine months ended September 30, 2020, respectively. The increase was primarily attributable to changes in our year over year taxable earnings mix.

The differences in the tax provision and benefit for the periods presented and the U.S. federal statutory rate is primarily due to foreign taxes in profitable jurisdictions and the recording of a full valuation allowance on our net deferred tax assets in certain jurisdictions including the United States.

The Company applies the discrete method provided in ASC 740 to calculate its interim tax provision.

14. Geographic Information

The following table presents the Company's total net revenue by geography based on the currency of the underlying transaction (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020			2021		2020
United States	$	40,948	$	12,691		$	97,304	$	54,317
International	12,419		9,177			30,192		25,031
Total net revenue	$	53,367	$	21,868		$	127,496	$	79,348

Except for the United Kingdom, no individual country, included in International net revenue, represents more than 10% of the total consolidated net revenue for any of the periods presented.

The increase in the United Kingdom's net revenue in the three months ended September 30, 2020, was primarily attributed to a payment for service fees received from a customer as part of an early termination agreement.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and with the audited financial statements included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (2020 Form 10-K) filed with the United States Securities and Exchange Commission (SEC) on March 1, 2021. In addition to historical condensed consolidated financial information, the following discussion and analysis contains forward-looking statements that are based upon current plans, expectations and beliefs that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” in our 2020 Form 10-K, our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021 and June 30, 2021, and this Quarterly Report on Form 10-Q. References herein to "Eventbrite," "the Company," "we," "us" or "our" refer to Eventbrite, Inc. and its subsidiaries, unless the context requires otherwise.

Overview

Eventbrite is a global self-service ticketing and experience technology platform that serves event creators and empowers their success. Our mission is to bring the world together through live experiences, and since inception, we have been at the center of the experience economy, helping to transform the way people organize and attend events. For more than a decade, Eventbrite has been meeting this core need and sparking human connection in nearly 180 countries.

The Eventbrite platform was built as a self-service platform to make it possible for anyone to create and sell tickets to live experiences. Creators—the people who bring others together to share their passions, artistry and causes through live experiences—are our North Star, and we have built, and continue to build, our platform to provide them with an intuitive, secure and reliable way to plan and execute their in-person and online events and scale their operations. We have a creator-aligned business model: we succeed when our creators succeed. We allow hosts of free events to use our platform for free and we charge creators of paid events on a per-ticket basis when an attendee purchases a ticket for an event. Our platform integrates seamlessly with internally-developed and third-party features designed to help our creators sell more tickets and scale their businesses.

We began to see increases in in-person events and ticket sales during the nine months ended September 30, 2021, and strong usage of the platform by frequent creators who hold multiple events per quarter. To support the needs of frequent creators we are reframing the Eventbrite product experience around the creator rather than the event. This means simplifying the event-creation workflow, introducing enhancements to the creator dashboard, and streamlining multiple-event management and reporting, making analysis easier and more actionable. As creators rebuild their businesses, we have introduced new tools and services like fully integrated Zoom capabilities and a new Calendar tool that we believe have increased event awareness.

In May 2021, we launched Eventbrite Boost which provides tools to event creators to increase their following on social networks, like Instagram and Facebook, create branded emails and marketing materials, track ticket sales, and optimize and automate their advertising. Eventbrite Boost helps creators make informed marketing decisions to grow their businesses. Real-time dashboards deliver personalized recommendations on the best marketing campaigns to run and also provide direct insight into how their campaigns are performing.

The global COVID-19 pandemic has tested our mission, our company and event creators in unprecedented ways. While our net revenue and paid ticket volume improved during the nine months ended September 30, 2021, we continue to experience a significant impact due to the COVID-19 pandemic and the social distancing and government mandates to restrict gatherings of people. Due to the COVID-19 pandemic, creators with published events in the remainder of 2021 may postpone or cancel these or other events. The COVID-19 pandemic is ongoing and significant uncertainty remains regarding the extent and duration of the impact that the COVID-19 pandemic will have on our business. The full extent to which COVID-19 impacts our business, results of operations and financial condition cannot be predicted at this time, and the impact of COVID-19 may persist for an extended period of time or become more pronounced.

In March 2021, we issued $212.75 million aggregate principal amount of 0.750% convertible senior notes due 2026 (2026 Notes) in a private offering, inclusive of the initial purchaser's exercise in full of its option to purchase additional notes. We used $153.2 million of the proceeds from this offering to repay in full the outstanding indebtedness under our May 2020 credit agreement and $18.5 million of the net proceeds from this offering to pay the cost of the 2026 Capped Calls transactions. We intend to use the remainder of the net proceeds from this offering for general corporate purposes.

Key Business Metrics and Non-GAAP Financial Measures

We monitor key metrics to help us evaluate our business, identify trends affecting our business, formulate business plans and make strategic decisions. In addition to revenue, net loss, and other results under GAAP, the following tables set forth key business metrics and non-GAAP financial measures we use to evaluate our business. We believe these metrics and measures are useful to facilitate period-to-period comparisons of our business. We believe that the use of Adjusted EBITDA is helpful to our investors as this metric is used by management in assessing the health of our business and our operating performance. This measure, which we refer to as our non-GAAP financial measure, is not prepared in accordance with GAAP and has limitations as an analytical tool, and you should not consider this in isolation or as substitutes for analysis of our results of operations as reported under GAAP. You are encouraged to evaluate the adjustments and the reasons we consider them appropriate.

Paid Ticket Volume

Our success in serving creators is measured in large part by the number of tickets sold on our platform that generate ticket fees, referred to as paid ticket volume. We consider paid ticket volume an important indicator of the underlying health of the business. The table below sets forth the paid ticket volume for the periods indicated:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2021	2020	2021	2020
	(in thousands)
Paid Ticket Volume	19,091	9,190	45,339	36,118

Our paid ticket volume for events outside of the United States represented 34% and 48% of our total paid tickets in the three months ended September 30, 2021 and 2020, respectively, and 35% and 45% for the nine months ended September 30, 2021 and 2020 respectively.

Adjusted EBITDA

Adjusted EBITDA is a key performance measure that our management uses to assess our operating performance. Because Adjusted EBITDA facilitates internal comparisons of our historical operating performance on a more consistent basis, we use this measure for business planning purposes and in evaluating acquisition opportunities.

We calculate Adjusted EBITDA as net loss adjusted to exclude depreciation and amortization, stock-based compensation expense, interest expense, loss on debt extinguishment, employer taxes related to employee equity transactions, other income (expense), net, which consisted of interest income, foreign exchange rate gains and losses, and income tax provision (benefit). Adjusted EBITDA should not be considered as an alternative to net loss or any other measure of financial performance calculated and presented in accordance with GAAP.

The following table presents our Adjusted EBITDA for the periods indicated and a reconciliation of our Adjusted EBITDA to the most comparable GAAP measure, net loss, for each of the periods indicated:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
	(in thousands)
Net loss	$	(16,813)	$	(19,427)	$	(122,244)	$	(204,487)
Add:
Depreciation and amortization	4,428		5,363		14,492		17,272
Stock-based compensation	12,300		10,107		35,985		30,541
Interest expense	2,814		10,284		13,200		13,921
Loss on debt extinguishment	—		—		49,977		—
Employer taxes related to employee equity transactions	400		218		1,875		912
Other (income) expense, net	2,460		(2,837)		2,882		5,262
Income tax provision (benefit)	311		243		885		307
Adjusted EBITDA	$	5,900	$	3,951	$	(2,948)	$	(136,272)

Some of the limitations of Adjusted EBITDA include (i) Adjusted EBITDA does not properly reflect capital spending that occurs off of the income statement or account for future contractual commitments, (ii) although depreciation and

28

amortization are non-cash charges, the underlying assets may need to be replaced and Adjusted EBITDA does not reflect these capital expenditures and (iii) Adjusted EBITDA does not reflect the interest and principal required to service our indebtedness. Our Adjusted EBITDA may not be comparable to similarly titled measures of other companies because they may not calculate Adjusted EBITDA in the same manner as we calculate the measure, limiting its usefulness as a comparative measure. In evaluating Adjusted EBITDA, you should be aware that in the future we will incur expenses similar to the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating our performance, you should consider Adjusted EBITDA alongside other financial performance measures, including our net loss and other GAAP results.

Net Revenue

We generate revenues primarily from service fees and payment processing fees from the sale of paid tickets on our platform. We also derive a portion of revenues from a series of marketing services and tools that enable creators to market their events and increase reach to attendees. Our fee structure typically consists of a flat fee and a percentage of the price of each ticket sold by a creator. Revenue is recognized when control of promised goods or services is transferred to the creator, which for service fees and payment processing fees is when the ticket is sold. Net revenue excludes sales taxes and value added taxes (VAT) and is presented net of estimated customer refunds, chargebacks and amortization of creator signing fees.

Net revenue	$	53,367	$	21,868	$	31,499	144	%	$	127,496	$	79,348	$	48,148	61	%

Total net revenue for the three and nine months ended September 30, 2021 increased by $31.5 million or 144% and $48.1 million or 61%, respectively, compared to the three and nine months ended September 30, 2020. Net revenue per paid ticket was $2.80 in the three months ended September 30, 2021 compared to $2.38 in the same period of 2020. Net revenue per paid ticket was $2.81 in the nine months ended September 30, 2021 compared to $2.20 in the same period of 2020. The increase in net revenue per paid ticket in the three and nine months ended September 30, 2021 was driven by the reduced impact of refunds per paid ticket reflecting a decrease in refunds due to COVID-related event cancellations.

The increase in net revenue during the three months ended September 30, 2021 compared to the same period in 2020 was primarily due to increase in our paid ticket volume which increased by 9.9 million or 108% as COVID-19 restrictions continued to ease.

The increase in net revenue during the nine months ended September 30, 2021 compared to the same period in 2020 was primarily due to increase in our paid ticket volume which increased by 9.2 million or 26% as COVID-19 restrictions continued to ease. Additionally, there was a decrease in refunds reserves of $18.7 million during the nine months ended September 30, 2021, driven by the reduction in COVID-related event cancellations and refund activity. The remainder of the increase in net revenue during the nine months ended September 30, 2021 was driven by a $5.0 million decrease in amortization of creator signing fees.

Cost of Net Revenue

Cost of net revenue consists of variable costs related to activities on our platform and fixed costs related to making our platform generally available. Our fixed costs consist primarily of expenses associated with the operation and maintenance of our platform, including website hosting fees and platform infrastructure costs, amortization of capitalized software development costs, onsite operations costs and allocated customer support costs. Cost of net revenue also includes the amortization expense related to our acquired developed technology assets, which may be incurred in future periods related to future acquisitions. Variable costs relate to creator activity and primarily consist of payment processing fees.

Generally, we expect cost of net revenue to fluctuate as a percentage of net revenue in the near- to mid-term primarily as a result of both our geographical revenue mix and our total net revenue. Our payment processing costs for credit and debit card payments are generally lower outside of the United States due to a number of factors, including lower card network fees and lower cost alternative payment networks. Consequently, if we generate more revenue internationally than in the United States, we expect that our payment processing costs will decline as a percentage of revenue. As our total net revenue increases or decreases and our fixed costs are unaffected, our cost of net revenue as a percentage of net revenue will similarly fluctuate.

Cost of net revenue for the three months ended September 30, 2021 increased by $7.0 million or 62% and increased for the nine months ended September 30, 2021 by $0.6 million or 1%, respectively, compared to the three and nine months ended September 30, 2020.

The increase in cost of net revenue during the three months ended September 30, 2021 compared to the same period in 2020 was primarily due to an increase of $7.0 million in payment processing costs in line with the increase in revenue from payment processing fees.

Cost of net revenue remained relatively consistent during the nine months ended September 30, 2021 compared to the same period in 2020. The change during the period comprised a $7.3 million increase in payment processing costs in line with the increase in revenue from payment processing fees. This was primarily offset by a $4.8 million decrease in allocated customer costs and field operations costs driven by change in business strategy to self-service creators, and a $1.7 million decrease in depreciation of equipment and amortization of capitalized internal-use software development costs.

Our gross margin improved during the three and nine months ended September 30, 2021 compared to the same period in 2020 primarily due to an increase in net revenue per paid ticket and cost savings driven by the change in business strategy to self-service creators requiring less customer support.

Operating Expenses

Operating expenses consist of product development, sales, marketing and support and general and administrative expenses. Direct and indirect personnel costs, including stock-based compensation expense, are the most significant recurring component of operating expenses. We also include sublease income as a reduction of our operating expenses.

As our total net revenue increases or decreases and to the extent our operating expenses are not equally affected, our operating expenses as a percentage of net revenue will similarly fluctuate.

Product development

Product development expenses consist primarily of costs associated with our employees in product development and product engineering activities. We expect our product development expenses to continue to increase in absolute dollars over the long term. In the near-term, we anticipate our product development expenses will increase as we focus on enhancing and expanding the capabilities of our platform. We also expect to continue investing in Eventbrite's infrastructure to enhance and support the development of new technologies. Over the long-term, we anticipate that product development expenses will decrease as a percentage of net revenue as our revenue recovers and grows and as we continue to expand our development staff in lower cost markets.

Product development expenses for the three and nine months ended September 30, 2021 increased by $5.1 million or 45% and $5.6 million or 13%, respectively, compared to the three and nine months ended September 30, 2020. The increase was primarily driven by employee-related costs including stock-based compensation as we continue to focus our investment on building technology products for our platform.

Sales, marketing and support

Sales, marketing and support expenses consist primarily of costs associated with our employees involved in selling and marketing our products, public relations and communication activities and marketing programs. For our sales teams, this also includes commissions. Sales, marketing and support expenses are driven by investments to grow and retain creators and attendees on our platform. Additionally, we classify certain creator-related expenses, such as refunds of the ticket price paid by us on behalf of a creator as sales, marketing and support expense.

Percentage of total net revenue	21		%	(23)		%					18		%	116		%

Sales, marketing and support expenses for the three months ended September 30, 2021 increased by $16.4 million or 327% and decreased for the nine months ended September 30, 2021 by $68.5 million or 75%, respectively, compared to the three and nine months ended September 30, 2020.

The increase in sales, marketing and support expenses during the three months ended September 30, 2021 compared to the same period in 2020 was primarily due to changes to our advance payout reserve. There was no change to our advance payout reserve during the three months ended September 30, 2021. Whereas, during the three months ended September 30, 2020, we recorded a $15.0 million reduction in reserve due to lower-than-anticipated losses since the start of the pandemic. This resulted in an overall increase to our sales, marketing and support expenses of $15.0 million during the three months ended September 30, 2021. The remaining increase was attributable to expenses for marketing our product and building brand awareness.

The decrease in sales, marketing and support expenses during the nine months ended September 30, 2021 compared to the same period in 2020 was primarily due to a decrease in advance payout reserve of $53.5 million, largely attributable to the conditions and effects of the COVID-19 pandemic and our estimated losses from advance payouts during 2020. Additionally, employee-related costs decreased by $11.9 million due to 50% lower headcount resulting from the reduction in workforce in April 2020.

32

General and administrative

General and administrative expenses consist of personnel costs, including stock-based compensation, and professional fees for finance, accounting, legal, risk, human resources and other corporate functions. It also includes accruals for indirect taxes such as sales tax and VAT, as well as reserves and impairment charges related to creator upfront payments.

General and administrative expenses for the three and nine months ended September 30, 2021 increased by $2.5 million or 16% and decreased $19.3 million or 24%, respectively, compared to the three and nine months ended September 30, 2020.

The increase in general and administrative expenses during the three months ended September 30, 2021 compared to the same period in 2020 was primarily due to employee-related costs including stock-based compensation.

The decrease in general and administrative expense during the nine months ended September 30, 2021 compared to the same period in 2020 was largely attributable to a $16.5 million decrease in creator upfront reserves due to the continued resolution of our exposure. The remainder of the decrease was primarily due to a $1.8 million decrease in certain indirect tax reserves due to statute of limitations lapses. Additionally, during the nine months ended September 30, 2021, we increased our accrual for existing litigation settlement which was offset by a reduction due to proceeds recoverable from our insurers.

Interest Expense

In March 2021, we issued the 2026 Notes, which consisted of $212.75 million aggregate principal amount of 0.750% convertible senior notes due 2026. In June 2020, we issued $150.0 million aggregate principal amount of 5.000% senior notes due 2025.

Interest expense consists primarily of cash interest expense and amortization of debt discount and issuance costs on our term loans under the May 2020 credit agreement, 2025 Notes and 2026 Notes. The credit agreement entered into in May 2020 was terminated on March 11, 2021.

Prior to the adoption of ASU 2020-06, we separated the conversion option of the 2025 Notes from the debt instrument and classified the conversion option in equity. We early adopted ASU 2020-06 on January 1, 2021, which resulted in the elimination of the debt discount created by bifurcating the conversion option in equity. Interest expense recognized in future periods will be reduced as a result of accounting for the convertible debt instrument as a single liability measured at its amortized cost and the termination of the May 2020 credit agreement.

Percentage of total net revenue	(5)		%	(47)		%					(10)		%	(18)		%

Interest expense for the three and nine ended September 30, 2021 decreased by $7.5 million or 73% and decreased by $0.7 million or 5%, respectively, compared to the three and nine months ended September 30, 2020.

The decrease in interest expense during the three months ended September 30, 2021 compared to the same period in 2020 was primarily due to a $6.7 million decrease in interest on the term loans which were outstanding during the three months ended September 30, 2020 but were repaid in the first quarter of 2021. The remaining decrease was largely attributable to our adoption of ASU 2020-06 resulting in a lower effective interest on the 2025 Notes.

Interest expense remained relatively consistent during the nine months ended September 30, 2021 compared to the same period in 2020. There was a $4.4 million decrease in interest on the term loans as it was repaid in the first quarter of 2021. This was offset by an increase of $3.6 million interest on the 2025 Notes and 2026 Notes which were issued in June 2020 and March 2021, respectively. For the 2025 Notes, the interest incurred over nine months in 2021 compared to four months in 2020, exceeded the reduction in effective interest due to the adoption of ASU 2020-06.

Loss on debt extinguishment

In March 2021, we repaid in full the outstanding indebtedness under our May 2020 credit agreement by making payments of $125.0 million of principal, a $18.2 million make-whole premium, $9.0 million payment in kind interest and $1.0 million of accrued interest.

Percentage of total net revenue	—	%	—	%				(39)		%	—	%

We recorded a loss on debt extinguishment of $50.0 million during nine months ended September 30, 2021. The loss primarily related to the write-off of unamortized debt discount and issuance costs of $31.8 million and make-whole premiums of $18.2 million. Unamortized debt discounts primarily related to 2,599,174 shares of Class A common stock issued to the FP EB Aggregator, L.P. for a purchase price of $0.01 per share. We accounted for these shares at fair value and recorded $27.4 million as debt discount at issuance. The remaining unamortized discounts and issuance costs relate to the cash costs incurred during the issuance of the term loan.

Other Income (Expense), Net

Other income (expense), net consists primarily of interest income and foreign exchange rate remeasurement gains and losses recorded from consolidating our subsidiaries each period-end. The primary driver of our other income (expense), net is fluctuation in the value of the U.S. dollar against the local currencies of our foreign subsidiaries.

	2021			2020			$ Change		% Change		2021			2020			$ Change		% Change

Percentage of total net revenue	(5)		%	13		%					(2)		%	(7)		%

The increase in other expense during the three months ended September 30, 2021 compared to the same period of 2020 was driven by foreign currency rate measurement fluctuations. We recognized foreign currency rate remeasurement losses during the three months ended September 30, 2021, as a result of the strengthening of the U.S. dollar compared to the currencies with which we operate and process transactions.

The decrease in other expense during the nine months ended September 30, 2021 compared to the same period of 2020 was driven by foreign currency rate measurement fluctuation. We recognized less foreign currency rate remeasurement losses during the nine months ended September 30, 2021, as a result of the weakening of the U.S. dollar compared to the currencies with which we operate and process transactions.

Income Tax Provision (Benefit)

Income tax provision consists primarily of U.S. federal and state income taxes and income taxes in certain foreign jurisdictions in which we conduct business. The differences in the tax provision and benefit for the periods presented and the U.S. federal statutory rate is primarily due to foreign taxes in profitable jurisdictions and the recording of a full valuation allowance on our deferred tax assets in certain jurisdictions including the United States. We apply the discrete method provided in ASC Topic 740 to calculate our interim tax provision.

The provision for income taxes for the three and nine months ended September 30, 2021 increased by $0.1 million and $0.6 million, respectively, compared to the three and nine months ended September 30, 2020. The increase was primarily attributable to changes in our year over year taxable earnings mix.

Liquidity and Capital Resources

As of September 30, 2021, we had cash and cash equivalents of $667.9 million. Our cash and cash equivalents includes bank deposits and money market funds held by financial institutions and is held for working capital purposes. Collectively, our cash and cash equivalents balances represent a mix of cash that belongs to us and cash that is due to creators. The amounts due to creators, which were $327.6 million as of September 30, 2021, are captioned on our consolidated balance sheets as accounts payable, creators. Although creator cash is legally unrestricted, we do not utilize creator cash for our own financing or investing activities as the amounts are payable to creators on a regular basis. As of September 30, 2021, approximately 25% of our cash was held outside of the United States. The cash was held primarily on behalf of, and to be remitted to, creators and to fund our foreign operations. We do not expect to incur significant taxes related to these amounts.

In March 2021, we completed a private offering of the 2026 Notes and received aggregate net proceeds of $207.0 million after deducting the initial purchaser's discounts and commissions and debt issuance costs of $5.7 million. In connection with the offering of the 2026 Notes, we entered into capped call transactions with certain financial institutions. We used $153.2 million of the proceeds from this offering to repay in full the outstanding indebtedness under our May 2020 credit agreement and $18.5 million of the net proceeds from the offering to pay the cost of the 2026 Capped Calls. We intend to use the remainder of the net proceeds from the offering for general corporate purposes. See Note 8 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for additional information about the 2026 Notes and 2026 Capped Calls.

In the second quarter of 2021, we relaunched advance payouts to paid creators who qualify and accept our terms and conditions. As of September 30, 2021, advance payouts outstanding was approximately $300.0 million including $67.7 million of advance payouts issued since the third quarter of 2020, when we resumed the advance payout program on a limited basis.

The terms of our standard merchant agreement obligate creators to repay us for ticket sales advanced under such circumstances. However, we may not be able to recover our losses from these events, and COVID-19 has increased the likelihood that we will not recover these losses. Such unrecoverable amounts could equal up to the value of the ticket sales or amounts settled to the creator prior to the event that has been postponed or cancelled or is otherwise disputed. We record estimates for losses related to chargebacks and refunds of the face value of tickets based on various factors, including the amounts paid and outstanding to creators in conjunction with the advance payout program, the size and nature of future events, the remaining time to event date, and actual chargeback and refund activity during the current year. Due to the nature of the COVID-19 pandemic and the limited amount of currently available data, there is a high degree of uncertainty around these reserves and our actual losses could be materially different from our current estimates. We will adjust our recorded reserves in the future to reflect our best estimates of future outcomes, and we may pay in cash a portion of, all of, or a greater amount than the $23.0 million provision recorded as of September 30, 2021.

Previously we made payments of our funds to creators to provide the creator with short-term liquidity in advance of ticket sales. These amounts are recovered by us as tickets are sold by the respective creator, and are typically expected to be recovered within 12 months of the payment date. We maintain an allowance for estimated creator advances that are not recoverable and present the creator advances balances net on our condensed consolidated balance sheets. Creator advances, net were $2.2 million and $6.7 million as of September 30, 2021 and December 31, 2020, respectively.

We believe that our existing cash, including proceeds from the 2025 Notes and 2026 Notes, together with cash generated from operations, will be sufficient to meet our anticipated cash needs for at least the next 12 months. However, our liquidity assumptions may prove to be incorrect, and we could exhaust our available financial resources sooner than we currently expect.

Net increase in cash, cash equivalents and restricted cash	$	161,215	$	122,988

Comparison of Nine Months Ended September 30, 2021 and 2020

Cash Flows from Operating Activities

The net cash provided by operating activities for the nine months ended September 30, 2021 was $116.2 million, which primarily resulted from our net loss of $122.2 million, adjusted for non-cash charges primarily consisting of $50.0 million loss on debt extinguishment, $36.0 million stock-based compensation expense, $14.5 million depreciation and amortization, and $5.6 million non-cash interest expense. Additional cash was provided by changes in working capital consisting of a $136.5 million increase in accounts payable to creators due to an increase in paid ticket volume.

The net cash used in operating activities for the nine months ended September 30, 2020 was $124.0 million which primarily resulted from our net loss of $204.5 million, adjusted for non-cash charges primarily consisting of $73.2 million provision for chargebacks and refunds, $30.5 million stock-based compensation expense, $17.3 million depreciation and amortization, and $5.8 million non-cash interest expense. Additional cash was used in changes in working capital consisting of a $90.1 million decrease in accounts payable to creators and $45.3 million decrease in funds receivable. These changes to working capital were primarily driven by the decrease in paid ticket volume due to the COVID-19 pandemic.

Cash Flows from Investing Activities

The net cash used in investing activities of $1.7 million for the nine months ended September 30, 2021 consisted of $1.1 million capitalized internal-use software development costs and $0.5 million purchases of property and equipment.

The net cash used in investing activities of $4.6 million for the nine months ended September 30, 2020 consisted of $3.3 million capitalized software development costs and $1.3 million purchases of property and equipment.

Cash Flows from Financing Activities

The net cash provided by financing activities of $46.6 million during the nine months ended September 30, 2021 was primarily due to $207.0 million proceeds from issuing the 2026 Notes, net of issuance costs, and $10.3 million proceeds from the exercise of stock options, offset by $143.2 million repayment of term loans including prepayment premium, $18.5 million purchase of the 2026 Capped Calls in connection with the issuance of the 2026 Notes and $9.4 million taxes paid related to net share settlement of equity awards.

The net cash provided by financing activities of $251.6 million during the nine months ended September 30, 2020 was primarily due to $256.7 million proceeds from issuing the term loans and 2025 Notes, net of issuance costs, and $14.1 million proceeds from the exercise of stock options, partially offset by $15.6 million purchase of the 2025 Capped Calls in connection with the issuance of the 2025 Notes and $4.0 million taxes paid related to net share settlement of equity awards.

Contractual Obligations and Commitments

Our principal commitments consist of obligations under the 2025 Notes and 2026 Notes (including principal and coupon interest), operating leases for office space, future creator signing fees and creator advances, as well as non-cancellable purchase

36

commitments. See Note 10 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for additional information.

Off-Balance Sheet Arrangements

We do not currently have any off-balance sheet arrangements and did not have any such arrangements as of September 30, 2021.

Critical Accounting Policies and Estimates

Our unaudited condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances, and we evaluate our estimates and assumptions on an ongoing basis. Due to the ongoing COVID-19 pandemic, there is uncertainty and significant disruption in the global economy and financial markets. We have had to make significant estimates in our unaudited condensed consolidated financial statements, specifically related to chargebacks and refunds due to cancelled or postponed events. We are not aware of any specific event or circumstance that would require an update to our estimates or assumptions or a revision of the carrying value of assets or liabilities as of the date of filing of this Quarterly Report on Form 10-Q. These estimates and assumptions may change in the future, however, as new events occur and additional information is obtained. Our actual results could differ from these estimates.

Our significant accounting policies are discussed in the "Notes to Consolidated Financial Statements, Note 2. Significant Accounting Policies" in the 2020 Form 10-K. There have been no significant changes to these policies that have had a material impact on our unaudited condensed consolidated financial statements and related notes, except as noted in Note 2 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Sensitivity

As of September 30, 2021, our 2025 Notes and 2026 Notes were outstanding, both of which are subject to fixed annual interest charges. We have therefore no financial or economic exposure associated with changes in interest rates. However, the fair value of these financial instruments may fluctuate when interest rates change or can be affected when the market price of our Class A common stock fluctuates. We carry the convertible senior notes at face value less unamortized issuance cost on our balance sheet, and we present the fair value for required disclosure purposes only.

Foreign Currency Risk

Many creators live or operate outside the United States, and therefore, we have significant ticket sales denominated in foreign currencies, most notably the British Pound, Euro, Canadian Dollar, Australian Dollar, Brazilian Real and Argentinian Peso. Our international revenue, as well as costs and expenses denominated in foreign currencies, expose us to the risk of fluctuations in foreign currency exchange rates against the U.S. dollar. Accordingly, we are subject to foreign currency risk, which may adversely impact our financial results. The functional currency of our international subsidiaries is the U.S. dollar. Movements in foreign exchange rates are recorded in other income (expense), net in our condensed consolidated statements of operations. We have experienced and will continue to experience fluctuations in foreign exchange gains and losses related to changes in exchange rates. If our foreign-currency denominated assets, liabilities, revenues, or expenses increase, our results of operations may be more significantly impacted by fluctuations in the exchange rates of the currencies in which we do business. A 10% increase or decrease in current exchange rates would not have a material impact on our consolidated results of operations.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of the principal executive officer and principal financial officer, conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this report.

Based on that evaluation, the principal executive officer and the principal financial officer concluded that, as of September 30, 2021, our disclosure controls and procedures were effective to provide reasonable assurance that the information required for disclosure in reports filed or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to Company management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosures.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that occurred during the quarter ended September 30, 2021 which have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Disclosure Controls and Procedures

In designing and evaluating the disclosure controls and procedures and internal control over financial reporting, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures and internal control over financial reporting must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

See "Note 10 - Commitments and Contingent Liabilities - Litigation and Loss Contingencies" in the Notes to the Unaudited Condensed Consolidated Financial Statements.

Item 1A. Risk Factors

There have been no material changes from the risk factors set forth in Part I, Item 1A, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (2020 Form 10-K) and Part II, Item 1A of our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021 and June 30, 2021. You should carefully consider the risks and uncertainties described in the 2020 Form 10-K and our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021 and June 30, 2021, together with all of the other information in our 2020 Form 10-K, and this Quarterly Report on Form 10-Q, including the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes, and other documents that we file with the U.S. Securities and Exchange Commission. The risks and uncertainties described in the 2020 Form 10-K and our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2021 and June 30, 2021 may not be the only ones we face. If any of the risks actually occur, our business, results of operations, financial condition and prospects could be harmed. In that event, the market price of our Class A common stock could decline, and you could lose part or all of your investment. Many of the risks and uncertainties are, and will be, exacerbated by the COVID-19 pandemic and any worsening of the global business and economic environment as a result.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Unregistered Sales of Equity Securities

There were no sales of unregistered equity securities during the three and nine months ended September 30, 2021 that were not previously reported on a Current Report on Form 8-K.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Overview and Basis of Presentation

Overview and Basis of Presentation

Description of Business

Eventbrite, Inc. (Eventbrite or the Company) has built a powerful, broad technology platform to enable creators to solve the challenges associated with creating in-person and online live experiences. The Company’s platform integrates components needed to seamlessly plan, promote and produce live events. To further enhance the value of the creators’ self-service experience, the Company is working to reframe the Eventbrite product around the ongoing operational needs of creators in addition to the requirements of individual events. To this end, the Company has improved events calendaring, streamlined the event creation process and launched tools to assist creators in promoting multiple events and increasing audience size for their events.

Basis of Presentation

The accompanying condensed consolidated financial statements of the Company are unaudited. The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and the applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal and recurring nature considered necessary to state fairly the Company's consolidated financial position, results of operations and cash flows for the interim periods. All intercompany transactions and balances have been eliminated. The interim results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or for any other future annual or interim period.

The information included in this Quarterly Report on Form 10-Q should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Quantitative and Qualitative Disclosures About Market Risk" and the Consolidated Financial Statements and notes thereto included in Items 7, 7A and 8, respectively, in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 (2020 Form 10-K).

Revision of Condensed Consolidated Financial Statements

As disclosed in the 2020 Form 10-K, the Company identified an error within the condensed consolidated statement of cash flows for the nine months ended September 30, 2020. The accompanying financial statements have been revised to correct for such error. The impact of such revision resulted in net cash used in operating activities decreasing by $3.3 million to $124.0 million and net cash provided by financing activities decreasing by $3.3 million to $251.6 million for the nine months ended September 30, 2020. The Company evaluated the error and concluded that it was not material to the September 30, 2020 financial statements previously issued. These revisions have no impact on the Company's previously reported consolidated net income, financial position, net change in cash, cash equivalents, and restricted cash, or total cash, cash equivalents, and restricted cash as reported on the Company's consolidated statements of cash flows.

Use of Estimates

In order to conform with U.S. GAAP, the Company is required to make certain estimates, judgments and assumptions when preparing its consolidated financial statements. These estimates, judgments and assumptions affect the reported assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reported periods. These estimates include, but are not limited to, the recoverability of creator signing fees and creator advances, the chargebacks and refunds reserve, the capitalization and estimated useful life of internal-use software, certain assumptions used in the valuation of equity awards, assumptions used in determining the fair value of business combinations, the allowance for doubtful accounts, indirect tax reserves and contra-revenue amounts related to fraudulent events, customer disputed transactions and refunds. The Company evaluates these estimates on an ongoing basis. Actual results could differ from those estimates and such differences could be material to the Company’s consolidated financial statements.

COVID-19 Impacts

The Company continues to experience a significant impact due to the COVID-19 pandemic, the introduction and spread of new variants of the virus, including, for example, the Delta variant, and the social distancing and government mandates to restrict gatherings of people. The effect of and uncertainties surrounding the COVID-19 pandemic have caused the Company to make significant estimates in its unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2021, specifically related to chargebacks and refunds due to cancelled or postponed events, which impact net revenue, advance payouts, creator signing fees and creator advances.

The COVID-19 pandemic is ongoing in nature and the Company will continue to revise such estimates in future reporting periods to reflect management's best estimates of future outcomes. Significant uncertainty remains regarding the extent and duration of the impact that the COVID-19 pandemic will have on the Company’s business. The full extent to which COVID-19 impacts the Company’s business, results of operations and financial condition cannot be predicted at this time, and the impact of COVID-19 may persist for an extended period of time or become more pronounced.

Comprehensive Loss

For all periods presented, comprehensive loss equaled net loss. Therefore, the condensed consolidated statements of comprehensive loss have been omitted from the unaudited condensed consolidated financial statements.

Segment Information

The Company’s Chief Executive Officer (CEO) is the chief operating decision maker. The Company's CEO reviews discrete financial information presented on a consolidated basis for purposes of allocating resources and evaluating the Company’s financial performance. Accordingly, the Company has determined that it operates as a single operating segment and has one reporting unit.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Topic 470) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Topic 815), which eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation.

The Company early adopted ASU 2020-06 on January 1, 2021 using the modified retrospective transition method. Adoption of ASU 2020-06 resulted in a decrease to additional paid-in capital of $45.5 million, an increase to retained earnings of $3.1 million, and a net increase to long-term debt of $42.4 million. Refer to Note 8 – Debt for more details. The Company will use the if-converted method to calculate diluted EPS unless it makes an irrevocable election to settle the principal of the notes in cash and the excess conversion spread in shares, in which case the Company can continue to use the Treasury stock method. Since the Company had a net loss for the three and nine months ended September 30, 2021 and 2020, the convertible senior notes were determined to be anti-dilutive and therefore had no impact to basic or diluted net loss per share for the period as a result of adopting ASU 2020-06.

The Company's significant accounting policies are discussed in the "Notes to Consolidated Financial Statements, Note 2. Significant Accounting Policies" in the 2020 Form 10-K. There have been no significant changes to these policies that have had a material impact on the Company's unaudited condensed consolidated financial statements and related notes, except as noted above.

Revenue Recognition

The Company derives its revenues primarily from ticketing and payment processing. The Company also derives a smaller portion of revenues from marketing services. The Company's customers are event creators who use the Company's platform to sell tickets and market events to attendees. Revenue is recognized when or as control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services.

Transaction Revenue

For ticketing services, the Company's service provides a platform to the event creator and attendee to transact. The Company's performance obligation is to facilitate and process that transaction and issue the ticket, and revenue is recognized by the Company when the ticket is sold. The amount that the Company earns for its services is fixed which typically consists of a flat fee and a percentage based fee per ticket. As a result, the Company records revenue on a net basis related to its ticketing service fees.

For payment processing services, the Company's service provides the event creator with the choice of whether to use Eventbrite Payment Processing (EPP) or to use a third-party payment processor, referred to as Facilitated Payment Processing (FPP).

Under the EPP option, the Company is the merchant of record and is responsible for processing the transaction and collecting the face value of the ticket and all associated fees at the time the ticket is sold. The Company is also responsible for remitting these amounts collected, less the Company's fees, to the event creator. For EPP services, the Company determined that it is the principal in providing the service as the Company is responsible for fulfilling the promise to process the payment and has discretion in establishing the price of its service. As a result, the Company records revenue on a gross basis related to its EPP service fees. Costs incurred for processing the ticketing transactions are included in cost of net revenues in the consolidated statements of operations. Under the FPP option, the Company is not responsible for processing the transaction or collecting the face value of the ticket and associated fees. In this case, the Company records revenue on a net basis related to its FPP service fees.

Revenue is presented net of indirect taxes, customer refunds, payment chargebacks, estimated uncollectible amounts, creator royalties, and amortization of creator signing fees. Previously, the Company offered upfront payments to creators entering into new or renewed ticketing arrangements. However, the Company is shifting from upfront payment incentives to performance based incentives on a limited basis. See Note 4. Creator Signing Fees, Net, for further information relating to signing fees paid.

If an event is cancelled by a creator, then any obligations to provide refunds to event attendees are the responsibility of that creator. If a creator is unwilling or unable to fulfill their refund obligations, the Company may, at its discretion, provide attendee refunds.

Marketing Revenue

Revenue from marketing services is derived from providing creators with access to various marketing tools and functionalities for a monthly subscription fee. The Company considers that it satisfies its performance obligation as it provides the services to customers and recognizes revenue ratably over the service term which varies from one month to a year.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents includes bank deposits and money market funds held with financial institutions. Cash and cash equivalents balances include the face value of tickets sold on behalf of creators and their share of service charges, which are to be remitted to the creators. Such balances were $310.0 million and $181.1 million as of September 30, 2021 and December 31, 2020, respectively. Although creator cash is legally unrestricted, the Company does not utilize creator cash for its own financing or investing activities as the amounts are payable to creators on a regular basis. These amounts due to creators are included in accounts payable, creators on the consolidated balance sheets. The Company considers all highly liquid investments, including money market funds with an original maturity of three months or less at the date of purchase, to be cash equivalents.

The Company has issued letters of credit under lease agreements and other agreements which have been collateralized with cash. This cash is classified as noncurrent restricted cash on the consolidated balance sheets. The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same amounts shown in the consolidated statements of cash flows (in thousands):

	September 30, 2021		December 31, 2020
Cash and cash equivalents	$	667,868	$	505,756
Restricted cash	1,777		2,674
Total cash, cash equivalents and restricted cash	$	669,645	$	508,430

Funds Receivable

Funds receivable represents cash-in-transit from third-party payment processors that is received by the Company within approximately five business days from the date of the underlying ticketing transaction. The funds receivable balances include the face value of tickets sold on behalf of creators and their share of service charges, which amounts are to be remitted to the creators. Such amounts were $17.6 million and $10.0 million as of September 30, 2021 and December 31, 2020, respectively.

Accounts Payable, Creators

Accounts payable, creators consists of unremitted ticket sale proceeds, net of Eventbrite service fees and applicable taxes. Amounts are remitted to creators within five business days subsequent to the completion of the related event. Creators may apply to receive a portion of these proceeds prior to completion of their events. For qualified creators, the Company passes ticket sales proceeds to the creator prior to the event, subject to certain limitations. Internally, the Company refers to these payments as advance payouts. When an advance payout is made, the Company reduces its cash and cash equivalents with a corresponding decrease to its accounts payable, creators.

As a result of the COVID-19 pandemic and its effect of causing creators to cancel, postpone or reschedule events, the Company temporarily suspended its advance payouts program on March 11, 2020. The Company started making advance payouts available to a limited number of qualified creators during the third quarter of 2020. In the second quarter of 2021, the Company relaunched Scheduled Payouts (advance payouts) to paid creators who qualify and accept the Company's terms and conditions. As of September 30, 2021, advance payouts outstanding was approximately $300.0 million including $67.7 million of advance payouts issued since the third quarter of 2020, when the Company resumed the advance payout program on a limited basis.

Chargebacks and Refunds Reserve

The terms of the Company's standard merchant agreement obligate creators to reimburse attendees who are entitled to refunds. When the Company provides advance payouts, it assumes risk that the event may be cancelled, fraudulent or materially not as described, resulting in significant chargebacks and refund requests. If the creator is insolvent or has spent the proceeds of the ticket sales for event-related costs, the Company may not be able to recover its losses from these events, and such unrecoverable amounts could equal the value of the transaction or transactions settled to the creator prior to the event that is disputed, plus any associated chargeback fees not assumed by the creator. The Company records estimates for refunds and chargebacks of its fees as contra-revenue. The Company records estimates for losses related to chargebacks and refunds of the face value of tickets as an operating expense classified within sales, marketing and support. Reserves are recorded based on the Company's assessment of various factors, including the amounts paid and outstanding to creators in conjunction with the advance payout program, the size and nature of future events, the remaining time to event date, and actual chargeback and refund activity during the current year.

Impairment of Long-lived Assets

The carrying amounts of long-lived assets, including property and equipment, capitalized internal-use software, acquired intangible assets and right-of-use operating lease assets are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful life is shorter than originally estimated. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to future undiscounted net cash flows the asset is expected to generate over its remaining life.

If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the revised shorter useful life.

Significant judgment and estimates are required in assessing impairment of long-lived assets, including identifying whether events or changes in circumstances require an impairment assessment, estimating future cash flows, and determining appropriate discount rates. As of September 30, 2021, management did not identify any events or changes in circumstances that would require an impairment assessment.

Fair Value Measurement

The Company measures its financial assets and liabilities at fair value at each reporting date using a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value:

Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 – Other inputs that are directly or indirectly observable in the marketplace.

Level 3 – Unobservable inputs that are supported by little or no market activity.

The Company’s cash equivalents, funds receivable, accounts receivable, accounts payable, funds payable and other current liabilities approximate their fair value. All such financial assets and liabilities are Level 1 and are measured at fair value on a recurring basis. There were no other Level 1 assets or liabilities recorded at September 30, 2021 and December 31, 2020.

Refer to Note 8 “Debt” for details regarding the fair value of our convertible senior notes.

Creator Signing Fees, Net

Creator Signing Fees, Net

Creator signing fees are incentives that are offered and paid by the Company to secure exclusive ticketing and payment processing rights with certain creators. The benefit the Company receives by securing exclusive ticketing and payment processing rights with certain creators from creator signing fees is inseparable from the customer relationship with the creator and accordingly these fees are recorded as a reduction of revenue in the consolidated statements of operations.

As of September 30, 2021, the balance of creator signing fees, net is being amortized over a weighted-average remaining contract life of 3.2 years on a straight-line basis. The following table summarizes the activity in creator signing fees for the periods indicated (in thousands):

Operating Leases

The Company has operating leases primarily for office space. The Company subleases certain leased office space to third parties when it determines there is excess leased capacity. Operating lease right-of-use assets and operating lease liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term. Right-of-use assets also include adjustments related to prepaid or deferred lease payments and lease incentives. In calculating the present value of the lease payments, the Company utilizes its incremental borrowing rate, as the rates implicit in the leases were not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located.

The components of operating lease costs were as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020
Operating lease costs	$	646	$	1,977	$	3,830	$	5,872

Total operating lease costs, net	$	589	$	895	$	2,458	$	2,748

As of September 30, 2021, the Company's operating leases had a weighted-average remaining lease term of 4.1 years and a weighted-average discount rate of 3.2%. Operating lease right-of-use assets obtained in exchange for operating lease obligations were $0.2 million and $2.3 million in the nine months ended September 30, 2021 and 2020 respectively.

In August 2021, the Company entered into a lease agreement for an office facility in San Francisco, California for which the lease term commenced on October 1, 2021 and will expire on September 29, 2023.

Operating Leases

The Company has operating leases primarily for office space. The Company subleases certain leased office space to third parties when it determines there is excess leased capacity. Operating lease right-of-use assets and operating lease liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term. Right-of-use assets also include adjustments related to prepaid or deferred lease payments and lease incentives. In calculating the present value of the lease payments, the Company utilizes its incremental borrowing rate, as the rates implicit in the leases were not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located.

The components of operating lease costs were as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,

Total operating lease costs, net	$	589	$	895	$	2,458	$	2,748

As of September 30, 2021, the Company's operating leases had a weighted-average remaining lease term of 4.1 years and a weighted-average discount rate of 3.2%. Operating lease right-of-use assets obtained in exchange for operating lease obligations were $0.2 million and $2.3 million in the nine months ended September 30, 2021 and 2020 respectively.

In August 2021, the Company entered into a lease agreement for an office facility in San Francisco, California for which the lease term commenced on October 1, 2021 and will expire on September 29, 2023.

Debt

Debt

The Company adopted ASU 2020-06, effective January 1, 2021 which resulted in decreased non-cash interest expense on the 5.000% convertible senior notes due 2025 (the 2025 Notes) due to the elimination of the discount associated with the equity component.

Term Loans

On March 11, 2021, the Company repaid all borrowings outstanding under the Credit Agreement, dated as of May 9, 2020 (and as amended on June 15, 2020), by and among the Company, FP EB Aggregator, L.P. (FP) and Wilmington Trust, National Association, as the administrative agent (the May 2020 credit agreement), and subsequently terminated the May 2020 credit agreement. In connection with the early termination of the borrowings outstanding under the May 2020 credit agreement, the Company paid $153.2 million, which consisted of $125.0 million in principal payments, a $18.2 million make-whole premium, $9.0 million payment in kind interest and $1.0 million of accrued cash interest.

In May 2020, in connection with the execution of the May 2020 credit agreement, the Company entered into a stock purchase agreement with FP to issue and sell 2,599,174 shares of Class A Common Stock to FP for a purchase price of $0.01 per share. The Company accounted for these shares at fair value and recorded $27.4 million as debt discount. The Company incurred total cash costs of $13.2 million, of which $7.6 million were third party offering costs and the remaining $5.6 million were lender fees, resulting in total debt issuance costs and discount of $40.6 million.

The Company recorded a loss on debt extinguishment of $50.0 million during nine months ended September 30, 2021. The loss primarily related to the write-off of unamortized debt discount and issuance costs of $31.8 million and a $18.2 million make-whole premium.

During the nine months ended September 30, 2021, the Company recorded $2.2 million payment in kind interest, $2.2 million amortization of debt discount and issuance costs, and $1.0 million cash interest. During the nine months ended September 30, 2020, the Company recorded $4.0 million payment in kind interest, $3.9 million amortization of debt discount and issuance costs, and $1.9 million cash interest.

Senior Notes

2025 Notes

In June 2020, the Company issued $150.0 million aggregate principal amount of 5.000% convertible senior notes due 2025 (the 2025 Notes), in a private offering to qualified institutional buyers. Interest is payable in cash semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020. The 2025 Notes mature on December 1, 2025, unless earlier repurchased, redeemed or converted. The total net proceeds from the 2025 Notes, after deducting the debt issuance costs of $5.7 million, was $144.3 million.

Prior to the adoption of ASU 2020-06, the Company separated the conversion option of the 2025 Notes from the debt instrument and classified the conversion option in equity. The 2025 Notes were not issued at a substantial premium. ASU 2020-06 eliminates the cash conversion model in ASC 470-20, no longer requiring the Company to account for the embedded conversion feature as a component of equity. As a result, the Company now accounts for the 2025 Notes as a single unit of account.

The adoption of ASU 2020-06 primarily had the following impact on the Company's financial statements:

•Recognition of additional $45.5 million in long term debt on the consolidated balance sheet as of January 1, 2021. This relates to the derecognition of the conversion option which was previously classified as equity.

•A cumulative effect adjustment was recognized to the opening balance of retained earnings of $3.1 million. This relates to the decreased interest expense on the 2025 Notes for fiscal 2020 due to the elimination of the discount resulting from the recognition of the equity component.

•The deferred taxes previously recognized upon the issuance of the 2025 Notes were reversed upon the adoption of ASU 2020-06 through equity and were offset by a valuation allowance, resulting in no income tax impact to the consolidated financial statements.

The effective interest rate of the 2025 Notes is 5.8%. During the nine months ended September 30, 2021, the Company recorded cash interest of $5.6 million, and amortization of debt issuance costs of $0.7 million. During the nine months ended September 30, 2020, the Company recorded cash interest of $2.2 million, and amortization of debt discount and issuance costs of $1.9 million.

The 2025 Notes are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the 2025 Notes; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries.

The terms of the 2025 Notes are governed by an Indenture by and between the Company and Wilmington Trust, National Association, as Trustee (the Indenture). The Company may irrevocably elect a settlement in cash, shares of Class A common stock, or a combination of cash and shares of Class A common stock.

The 2025 Notes are convertible at an initial conversion rate of 79.3903 shares of Class A common stock per $1,000 principal amount of 2025 Notes, which is equal to an initial conversion price of approximately $12.60 per share of Class A common stock. The conversion rate is subject to adjustment under certain circumstances in accordance with the terms of the Indenture. Holders of the 2025 Notes may convert all or a portion of their 2025 Notes only in multiples of $1,000 principal amount, under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the last reported sale price per share of our Class A common stock exceeds 130% of the conversion price of the 2025 Notes for each of the at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter;

•during the five consecutive business days immediately after any 10 consecutive trading day period in which the trading price per $1,000 principal amount of 2025 Notes for each trading day of that 10 consecutive trading day period was less than 98% of the product of the last reported sale price of Class A common stock and the conversion rate on such trading day;

•upon the occurrence of certain corporate events or distributions on the Company's Class A common stock, as described in the Indenture;

•if the Company calls the 2025 Notes for redemption; or

•at any time from, and including, June 2, 2025 until the close of business on the second scheduled trading day immediately before the maturity date.

Holders of the 2025 Notes who convert their 2025 Notes in connection with certain corporate events that constitute a make-whole fundamental change (as defined in the Indenture) are, under certain circumstances, entitled to an increase in the conversion rate.

No sinking fund is provided for the 2025 Notes. The 2025 Notes are redeemable, in whole or in part, at the Company's option at any time and from time to time, on or after June 1, 2023 and on or before the 40th scheduled trading day immediately prior to the maturity date, at a cash redemption price equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of Class A common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading dates ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such notice. Additionally, calling any of the 2025 Notes for redemption will constitute a make-whole fundamental change with respect to that portion of the 2025 Notes, in which case the conversion rate applicable to the conversion of those 2025 Notes will be increased in certain circumstances (as described in the Indenture) if it is converted after it is called for redemption.

If certain corporate events that constitute a “Fundamental Change” (as defined in the Indenture) occur, then, subject to a limited exception for certain cash mergers, note holders may require the Company to repurchase their 2025 Notes at a cash repurchase price equal to the principal amount of the 2025 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change repurchase date. The definition of Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s Class A common stock.

The 2025 Notes have customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), which include the following: (i) certain payment defaults on the 2025 Notes; (ii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iii) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person; (iv) a default by the Company in its other obligations or agreements under the Indenture or the 2025 Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; (v) the rendering of certain judgments against the Company or any of its subsidiaries for the payment of at least $10,000,000, where such judgments are not discharged or stayed within 45 days after the date on which the right to appeal has expired or on which all rights to appeal have been extinguished; (vi) certain defaults by the Company or any of its significant subsidiaries with respect to indebtedness for borrowed money of at least $10,000,000; and (vii) certain events of bankruptcy, insolvency and reorganization involving the Company or any of the Company’s significant subsidiaries.

If an Event of Default involving bankruptcy, insolvency or reorganization events with respect to the Company (and not solely with respect to a significant subsidiary of the Company) occurs, then the principal amount of, and all accrued and unpaid interest on, all of the 2025 Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other Event of Default occurs and is continuing, then, the Trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of 2025 Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the 2025 Notes then outstanding to become due and payable immediately. However, notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an Event of Default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on the 2025 Notes for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the 2025 Notes.

The fair value of the 2025 Notes, which we have classified as a Level 2 instrument, was $260.2 million as of September 30, 2021. The fair value of the 2025 Notes is determined using observable market prices on the last business day of the period.

2026 Notes

In March 2021, the Company issued $212.75 million aggregate principal amount of 0.750% convertible senior notes due 2026 (the 2026 Notes) in a private offering to qualified institutional buyers, inclusive of the initial purchaser's exercise in full of its option to purchase additional notes. The 2026 Notes bear interest at a fixed rate of 0.750% per year. Interest is payable in cash semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2021. The 2026 Notes mature on September 15, 2026 unless earlier repurchased, redeemed or converted. The total net proceeds from the 2026 Notes, after deducting debt issuance costs of $5.7 million, was $207.0 million.

The 2026 Notes are the Company’s senior, unsecured obligations and are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s existing and future indebtedness that is expressly subordinated to the 2026 Notes and effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness; and (iii) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries.

Before March 15, 2026, noteholders will have the right to convert their 2026 Notes under the following circumstances:

•during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price per share of our Class A common stock exceeds 130% of the conversion price for each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter;

•during the five consecutive business days immediately after any 10 consecutive trading day period in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of our Class A common stock on such trading day and the conversion rate on such trading day;

•upon the occurrence of certain corporate events or distributions on our Class A common stock, as described in the Indenture and

•if the Company call such notes for redemption;

From and after March 15, 2026, noteholders may convert their 2026 Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. Upon conversion, the 2026 Notes may be settled in cash, shares of Class A common stock, or a combination of cash and shares of Class A common stock, at the Company's election. The Company may irrevocably elect a settlement in cash, shares of Class A common stock, or a combination of cash and shares of Class A common stock.

The 2026 Notes are convertible at an initial conversion rate of 35.8616 shares of Class A common stock per $1,000 principal amount of 2026 Notes, which is equal to an initial conversion price of approximately $27.89 per share of Class A common stock. The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events. In addition, if certain corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time.

No sinking fund is provided for the 2026 Notes. The 2026 Notes will be redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after March 15, 2024 and on or before the 40th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid interest, if any, but only if the last reported sale price per share of the Company’s Class A common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such notice. In addition, calling any 2026 Note for redemption will constitute a Make-Whole Fundamental Change with respect to that Note, in which case the conversion rate applicable to the conversion of that 2026 Note will be increased in certain circumstances if it is converted after it is called for redemption.

If certain corporate events that constitute a “Fundamental Change” (as defined in the Indenture) occur, then, subject to a limited exception for certain cash mergers, noteholders may require the Company to repurchase their 2026 Notes at a cash repurchase price equal to the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid interest, if any. The definition of Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s Class A common stock.

The 2026 Notes have customary provisions relating to the occurrence of “Events of Default” (as defined in the Indenture), which include the following: (i) certain payment defaults on the Notes (which, in the case of a default in the payment of interest on the Notes, will be subject to a 30-day cure period); (ii) the Company’s failure to send certain notices under the Indenture within specified periods of time; (iii) the Company’s failure to comply with certain covenants in the Indenture relating to the Company’s ability to consolidate with or merge with or into, or sell, lease or otherwise transfer, in one transaction or a series of transactions, all or substantially all of the assets of the Company and its subsidiaries, taken as a whole, to another person; (iv) a default by the Company in its other obligations or agreements under the Indenture or the Notes if such default is not cured or waived within 60 days after notice is given in accordance with the Indenture; (v) certain defaults by the Company or any of its significant subsidiaries with respect to indebtedness for borrowed money of at least $10,000,000; and (vi) certain events of bankruptcy, insolvency and reorganization involving the Company or any of the Company’s significant

subsidiaries.

If an Event of Default involving bankruptcy, insolvency or reorganization events with respect to the Company (and not solely with respect to a significant subsidiary of the Company) occurs, then the principal amount of, and all accrued and unpaid interest on, all of the 2026 Notes then outstanding will immediately become due and payable without any further action or notice by any person. If any other Event of Default occurs and is continuing, then the Trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of Notes then outstanding, by notice to the Company and the Trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the 2026 Notes then outstanding to become due and payable immediately. However, notwithstanding the foregoing, the Company may elect, at its option, that the sole remedy for an Event of Default relating to certain failures by the Company to comply with certain reporting covenants in the Indenture consists exclusively of the right of the noteholders to receive special interest on the 2026 Notes for up to 180 days at a specified rate per annum not exceeding 0.50% on the principal amount of the 2026 Notes.

In accounting for the issuance of the 2026 Notes, total issuance costs of $5.7 million related to the 2026 Notes are being amortized to interest expense over the term of the 2026 Notes using the effective interest rate method.

The effective interest rate of the 2026 Notes is 1.3%. During the nine months ended September 30, 2021, the Company recorded cash interest of $0.9 million, and amortization of debt issuance costs of $0.6 million.

The fair value of the 2026 Notes, which we have classified as a Level 2 instrument, was $209.3 million as of September 30, 2021. The fair value of the 2026 Notes is determined using observable market prices on the last business day of the period.

Capped Call Transactions

In March 2021, in connection with the offering of the 2026 Notes, the Company entered into privately negotiated capped call transactions (2026 Capped Calls) with certain financial institutions (2026 Option Counterparties). The 2026 Capped Calls cover, subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the 2026 Notes, the number of shares of Class A common stock initially underlying the 2026 Notes. The 2026 Capped Calls are expected generally to reduce potential dilution to the Class A common stock upon any conversion of 2026 Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of such converted 2026 Notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the 2026 Capped Calls will initially be $37.5375 per share of Class A common stock, and is subject to certain customary adjustments under the terms of the 2026 Capped Calls. The 2026 Capped Calls will expire in September 2026, if not exercised earlier.

The 2026 Capped Calls are separate transactions entered into by the Company with each 2026 Option Counterparty, and are not part of the terms of the 2026 Notes and will not affect any noteholder’s rights under the 2026 Notes. Noteholders will not have any rights with respect to the 2026 Capped Calls.

The 2026 Capped Calls are subject to adjustment upon the occurrence of specified extraordinary events affecting the company, including merger events, tender offers and announcement events. In addition, the 2026 Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the 2026 Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings and hedging disruptions.

The 2026 Capped Call Transactions do not meet the criteria for separate accounting as a derivative. The aggregate premium paid for the purchase of the 2026 Capped Calls of $18.5 million was recorded as a reduction to additional paid-in capital on the consolidated balance sheets.

In June 2020, in connection with the offering of the 2025 Notes, the Company entered privately negotiated capped call transactions with certain financial institutions (2025 Capped Calls). The 2025 Capped Calls have an initial strike price of approximately $12.60 per share, which corresponds to the initial conversion price of the 2025 Notes. The 2025 Capped Calls

cover, subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the 2025 Notes, the number of shares of Class A common stock initially underlying the 2025 Notes. The 2025 Capped Calls are expected generally to reduce potential dilution to the Company’s Class A common stock upon any conversion of the 2025 Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted 2025 Notes, as the case may be, with such reduction and/or offset subject to a cap, initially equal to $17.1520, and is subject to certain adjustments under the terms of the 2025 Capped Call transactions. The 2025 Capped Calls will expire in December 2025, if not exercised earlier.

The 2025 Capped Calls are subject to adjustment upon the occurrence of specified extraordinary events affecting the company, including merger events, tender offers and announcement events. In addition, the 2025 Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the 2025 Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings and hedging disruptions. For accounting purposes, the 2025 Capped Calls are separate transactions, and not part of the terms of the Notes.

The 2025 Capped Call Transactions do not meet the criteria for separate accounting as a derivative. The aggregate premium paid for the purchase of the 2025 Capped Calls of $15.6 million was recorded as a reduction to additional paid-in capital on the consolidated balance sheets.

Goodwill and Acquired Intangible Assets, Net

Goodwill and Acquired Intangible Assets, Net

The carrying amounts of the Company's goodwill was $174.4 million as of September 30, 2021 and December 31, 2020.

The Company tests goodwill for impairment at least annually, in the fourth quarter, or whenever events or changes in circumstances would more likely than not reduce the fair value of its single reporting unit below its carrying value. As a result of a qualitative assessment, management concluded goodwill was not impaired as of September 30, 2021, and does not believe that its reporting unit is at risk of failing the impairment test since the fair value of the reporting unit substantially exceeded the carrying value.

Commitments and Contingencies

Commitments and Contingencies

The Company's principal commitments consist of obligations under the 2025 Notes and 2026 Notes (including principal and coupon interest), operating leases for office space, future creator signing fees and creator advances, as well as non-cancellable purchase commitments.

During the nine months ended September 30, 2021, the Company issued the 2026 Notes, which consisted of $212.75 million aggregate principal amount of 0.750% convertible senior notes due 2026 in a private offering. As of September 30, 2021, the Company's contractual obligation to settle commitments related to the principal amount of 2026 Notes is $212.75 million for the year ended December 31, 2026. The Company also entered into a lease arrangement in August 2021. The cumulative obligations payable by the Company over the term of the lease total $1.6 million. Other than as described above, there were no material changes outside the Company's normal course of business in its commitments under contractual obligations from those disclosed in the 2020 Form 10-K.

The following table summarizes the Company's contractual obligation to settle commitments related to the 2026 Notes and 2025 Notes as of September 30, 2021 (in thousands):

Litigation and Loss Contingencies

In addition to the litigation discussed below, from time to time, the Company may become a party to litigation and subject to claims incident to the ordinary course of business, including intellectual property claims, labor and employment claims, breach of contract claims, tax and other matters. Future litigation may be necessary to defend the Company or its creators.

The results of any current or future 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.

The Company accrues estimates for resolution of legal and other contingencies when losses are probable and estimable. The Company's assessment of losses is re-evaluated each accounting period and is based on all available information, including impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to each case. Nevertheless, it is possible that additional future legal costs including settlements, judgments, legal fees and other related defense costs could have a material adverse effect on the Company’s business, consolidated financial position, results of operations or liquidity.

The matters discussed below summarize the Company’s current ongoing pending litigation.

Refund Policy Litigation

On June 4, 2020, three plaintiffs, seeking to represent a proposed class of individuals who purchased tickets on or after June 3, 2016, filed suit against the Company in the United States District Court for the Northern District of California, in a case captioned Snow, et al. v. Eventbrite, Inc., Case No. 20-cv-03698 (the Class Action). Plaintiffs allege that Eventbrite failed to provide an opportunity for purchasers of tickets to events sold through Eventbrite’s platform to obtain a refund where the event is postponed, rescheduled, or canceled. Plaintiffs seek injunctive relief in addition to restitution and monetary damages under California’s Consumer Legal Remedies Act, False Advertising Law, and Unfair Competition Law, in addition to claims brought under California common law. The Company denies the allegations and intends to defend the case vigorously. The case is in its early stages. Prior to answering Plaintiffs’ complaint, Eventbrite brought a motion to compel arbitration pursuant to its Terms of Service. The Court denied that motion. The Company thereafter answered Plaintiffs’ Complaint and brought a second motion to compel arbitration, based in part on facts established via the Company’s Answer. The Court granted that motion on September 2, 2021, and stayed the suit pending the results of arbitration. Two of the named Plaintiffs have since initiated individual arbitrations pursuant to the Company’s Terms of Service. The Company has not yet filed any response or other paper in either proceeding. The Company is unable to predict the likely outcome at this point.

Securities Litigation

Beginning on April 15, 2019, purported stockholders of the Company filed two putative securities class action complaints in the United States District Court for the Northern District of California, and three putative securities class action complaints in the Superior Court of California for the County of San Mateo, against the Company, certain of its executives and directors, and its underwriters for the Company's initial public offering (IPO). Some of these actions also name as defendants venture capital firms that were investors in the Company as of the IPO.

On August 22, 2019, the federal court consolidated the two pending actions (the Federal Action). On October 11, 2019, the lead plaintiffs in the Federal Action filed an amended consolidated complaint. That complaint alleged that the Company misrepresented and/or omitted material information in its IPO offering documents in violation of the Securities Act. It also challenged public statements made after the IPO in violation of the Exchange Act. The amended complaint sought unspecified monetary damages and other relief on behalf of investors. On December 11, 2019, the defendants filed a motion to dismiss the amended complaint. On April 28, 2020, the court granted defendants’ motion to dismiss in its entirety with leave to amend and set a deadline of June 24, 2020 for lead plaintiff to file its second amended consolidated complaint. On June 22, 2020, the Court extended lead plaintiff’s deadline to file its second amended consolidated complaint to August 10, 2020.

On July 29, 2020, the Company entered into a settlement agreement with the lead plaintiff in the Federal Action. On August 27, 2020, the lead plaintiff in the Federal Action filed a motion for preliminary approval of the settlement. On October 21, 2020, the Court vacated the preliminary approval hearing, and on October 30, 2020, the Court issued an order continuing the preliminary approval hearing, tentatively rescheduling the hearing for March 18, 2021. On January 22, 2021, the Court issued an order denying without prejudice the motion for preliminary approval. On February 9, 2021, the Company gave notice to the lead plaintiff that, in light of the denial of the preliminary approval motion, it was terminating the settlement agreement.

On June 24, 2019, the state court consolidated two state actions pending at that time (the State Action). On July 24, 2019, the two plaintiffs in the State Action filed a consolidated complaint. The consolidated complaint generally alleged that the Company misrepresented and/or omitted material information in the IPO offering documents, in violation of the Securities Act, and sought unspecified monetary damages and other relief on behalf of investors. On August 23, 2019, defendants filed demurrers to the consolidated complaint, which the court sustained with leave to amend at a hearing on November 1, 2019. Plaintiffs filed a first amended consolidated complaint (FAC) on February 10, 2020. Defendants filed demurrers to the FAC on March 26, 2020. On June 23, 2020, the court sustained the demurrers with leave to amend. On November 9, 2020, the plaintiffs filed their second amended consolidated complaint (SAC). On November 20, 2020, defendants filed demurrers to the SAC, which were overruled on December 17, 2020. On January 15, 2021, defendants filed their answers to the SAC. On January 22, 2021, the plaintiffs filed a motion for class certification. On February 11, 2021, the parties stipulated to class certification, and on February 17, 2021, the Court entered an order certifying a class of “all persons and entities who purchased or otherwise acquired Eventbrite, Inc. Class A common stock pursuant or traceable to the Registration Statement and Prospectus issued in connection with Eventbrite’s September 2018 Initial Public Offering and who were damaged thereby.”

On October 26, 2021, the Company entered into a binding settlement agreement with the two plaintiffs in the State Action described above. In connection with the settlement, the Company and its insurers have agreed to pay $19.25 million. Accordingly, during the three months ended September 30, 2021, the Company increased its estimated liability recorded related to the securities litigation described above from $7.5 million to $19.25 million, which amount was included in "other accrued liabilities" in the accompanying condensed consolidated balance sheets as of September 30, 2021. Under the terms of the proposed settlement, which shall be paid by the Company and its insurers, the Company expects a contribution to be made by its insurers of approximately $12.5 million, which amount was included in "prepaid expenses and other current assets" in the accompanying condensed consolidated balance sheets as of September 30, 2021. The insurance contribution of approximately $12.5 million is recorded as a reduction to general and administrative expense during the three months ended September 30, 2021. The increase in estimated liability of $11.8 million is recorded as an increase to general and administrative expense during the three months ended September 30, 2021.

The proposed settlement “Class” is defined as “all persons and entities who purchased or otherwise acquired Class A common shares of Eventbrite between September 20, 2018, and May 24, 2019, inclusive,” excluding the defendants and other “Excluded Persons” defined in the settlement agreement. If the settlement is approved by the court in the State Action, any settlement “Class Member” that does not request exclusion from the proposed settlement “Class” will fully, finally, and forever release “any and all rights, liabilities, suits, debts, obligations, demands, damages, losses, judgment matters, issues, claims . . . and causes of action of every nature and description whatsoever that have been or could have been asserted in the [State] Action or the Federal Action or could in the future be asserted in any forum . . . whether individual, class, representative, on behalf of others, legal, equitable, regulatory, governmental, or of any other type or in any other capacity, whether brought directly or indirectly against any of the Defendants, that (i) arise out of, are based upon, or relate to in any way to any of the allegations, acts, transactions, facts, events, matters, occurrences, representations, or omissions which were or could have been alleged in the [State] Action or the Federal Action, and (ii) arise out of, are based upon, or relate to in any way to the purchase, acquisition, holding, sale, or disposition of Eventbrite Class A common stock between September 20, 2018 and May 24, 2019, inclusive.”

As of this filing, the plaintiffs in the State Action have not yet filed a motion for preliminary approval of the proposed settlement. Final approval of the settlement is subject to a number of conditions and contingencies outside of the Company’s control. There can be no guarantee that all of those conditions and contingencies to final approval of the settlement will occur. Should a material condition or contingency to the settlement fail to occur, one or both of the parties to the settlement may exercise their right to terminate the settlement agreement.

Commercial Contract Litigation

On June 18, 2020, the Company filed a Complaint in the United States District Court for the Northern District of California against M.R.G. Concerts Ltd. (MRG) and Matthew Gibbons (Gibbons), asserting claims for breach of contract, breach of the implied covenant of good faith and fair dealing, declaratory judgment, unfair competition, and common counts under California law, arising out of MRG and Gibbons’s termination of certain contracts with the Company and their refusal to make various payments to the Company required by those contracts. MRG asserted counterclaims against the Company for breach of one of the contracts in issue, as well as for breach of the implied covenant of good faith and fair dealing, unfair competition, and declaratory judgment. On October 1, 2020, the Company moved to dismiss MRG’s counterclaims and certain of MRG and Gibbons’s affirmative defenses. The Court denied Eventbrite’s motion. Fact discovery and expert discovery have closed. The Company has filed motions for summary judgment in its favor, and to exclude Defendants’ proffered expert testimony. Those motions remain pending. The Company cannot presently predict the likelihood of success.

Tax Matters

The Company is currently under audit in certain jurisdictions with regard to indirect tax matters. The Company establishes reserves for indirect tax matters when it determines that the likelihood of a loss is probable, and the loss is reasonably estimable. Accordingly, the Company has established a reserve for the potential settlement of issues related to sales and other indirect taxes in the amount of $10.1 million and $13.6 million as of September 30, 2021 and December 31, 2020, respectively. These amounts, which represent management’s best estimates of its potential liability, include potential interest and penalties of $1.5 million as of September 30, 2021 and December 31, 2020.

The Company does not believe that any ultimate liability resulting from any of these matters will have a material adverse effect on its business, consolidated financial position, results of operations or liquidity. However, the outcome of these matters is inherently uncertain. Therefore, if one or more of these matters were resolved against the Company for amounts in excess of management’s expectations, the Company’s financial statements, including in a particular reporting period in which any such outcome becomes probable and estimable, could be materially adversely affected.

Indemnification In the ordinary course of business, the Company enters into contractual arrangements under which the Company agrees to provide indemnification of varying scope and terms to business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of the breach of such agreements, intellectual property infringement claims made by third parties, and other liabilities relating to or arising from the Company’s online ticketing platform or the Company’s acts or omissions. In these circumstances, payment may be conditional on the other party making a claim pursuant to the procedures specified in the particular contract. Further, the Company’s obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments. In addition, the Company has indemnification agreements with its directors and executive officers that require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The terms of such obligations vary.

Stockholders' Equity

Stockholders' Equity

Equity Incentive Plans

In August 2018, the 2018 Stock Option and Incentive Plan (2018 Plan) was adopted by the board of directors and approved by the stockholders and became effective in connection with the IPO. The 2018 Plan replaced the 2010 Stock Plan (2010 Plan) as the board of directors determined not to make additional awards under the 2010 Plan. The 2010 Plan will continue to govern outstanding equity awards granted thereunder.

The 2018 Plan allows for the granting of options, stock appreciation rights, restricted stock, restricted stock units (RSUs), unrestricted stock awards, dividend equivalent rights and cash-based awards. Every January 1, the number of shares of stock reserved and available for issuance under the 2018 Plan will cumulatively increase by five percent of the number of shares of Class A and Class B common stock outstanding on the immediately preceding December 31, or a lesser number of shares as approved by the board of directors.

As of September 30, 2021, there were 8,306,321 and 4,998,430 options issued and outstanding under the 2010 Plan and 2018 Plan, respectively (collectively, the Plans), and 8,614,869 shares of Class A common stock were available for grant under the 2018 Plan.

Stock options granted typically vest over a four-year period from the date of grant. Options awarded under the Plans may be granted at an exercise price per share not less than the fair value at the date of grant and are exercisable up to ten years.

Stock Option Activity

Stock option activity for the nine months ended September 30, 2021 is presented below:

	Outstanding options	Weighted average exercise price	Weighted average remaining contractual term (years)	Aggregate intrinsic value (thousands)

Net Loss Per Share

Sep. 30, 2021

Earnings Per Share [Abstract]

Net Loss Per Share

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potentially dilutive securities outstanding for the period. As the Company had net losses for the quarters ended September 30, 2021 and 2020, all potentially issuable shares of common stock were determined to be anti-dilutive.

The following table sets forth the computation of basic and diluted net loss per share (in thousands, except per share data):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020			2021		2020
Net loss	$	(16,813)	$	(19,427)		$	(122,244)	$	(204,487)
Weighted-average shares used in computing net loss per share, basic and diluted	94,462		90,973			93,794		88,441
Net loss per share, basic and diluted	$	(0.18)	$	(0.21)		$	(1.30)	$	(2.31)

The following outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share because including them would have had an anti-dilutive effect (in thousands):

	September 30, 2021	September 30, 2020
Stock-options to purchase common stock	13,305	14,493
Shares related to convertible senior notes	19,538	11,909
Restricted stock units	4,767	4,141
ESPP	52	—
Total shares of potentially dilutive securities	37,662	30,543

Prior to January 1, 2021, the Company used the treasury stock method for calculating any potential dilutive effect of the conversion spread on net loss per share, if applicable. After the adoption of ASU 2020-06, the Company used the if-converted method for calculating any potential dilutive effect of its convertible senior notes for the three and nine months ended September 30, 2021. The potential impact upon the conversion of the convertible senior notes were excluded from the calculation of diluted net loss per share for the three and nine months ended September 30, 2021 because their effect would have been anti-dilutive.

For the 2026 Notes, the conversion spread of 7.6 million shares will have a dilutive impact on diluted net income per share of common stock when the average market price of the Company’s Class A common stock for a given period exceeds the conversion price of $27.89 per share. Although the average market price of the Company's Class A common stock exceeds the conversion price of $12.60 per share for the 2025 Notes, the conversion spread of 11.9 million shares did not impact the net loss per share calculation as it would have an anti-dilutive effect.

Income Taxes

The Company recorded income tax expense of $0.3 million and $0.9 million for the three and nine months ended September 30, 2021, respectively, compared to income tax expense of $0.2 million and $0.3 million for the three and nine months ended September 30, 2020, respectively. The increase was primarily attributable to changes in our year over year taxable earnings mix.

The differences in the tax provision and benefit for the periods presented and the U.S. federal statutory rate is primarily due to foreign taxes in profitable jurisdictions and the recording of a full valuation allowance on our net deferred tax assets in certain jurisdictions including the United States.

The Company applies the discrete method provided in ASC 740 to calculate its interim tax provision.

Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

The accompanying condensed consolidated financial statements of the Company are unaudited. The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and the applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal and recurring nature considered necessary to state fairly the Company's consolidated financial position, results of operations and cash flows for the interim periods. All intercompany transactions and balances have been eliminated. The interim results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or for any other future annual or interim period.

The information included in this Quarterly Report on Form 10-Q should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Quantitative and Qualitative Disclosures About Market Risk" and the Consolidated Financial Statements and notes thereto included in Items 7, 7A and 8, respectively, in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 (2020 Form 10-K).

Revision of Consolidated Financial Statements

the Company identified an error within the condensed consolidated statement of cash flows for the nine months ended September 30, 2020. The accompanying financial statements have been revised to correct for such error. The impact of such revision resulted in net cash used in operating activities decreasing by $3.3 million to $124.0 million and net cash provided by financing activities decreasing by $3.3 million to $251.6 million for the nine months ended September 30, 2020. The Company evaluated the error and concluded that it was not material to the September 30, 2020 financial statements previously issued. These revisions have no impact on the Company's previously reported consolidated net income, financial position, net change in cash, cash equivalents, and restricted cash, or total cash, cash equivalents, and restricted cash as reported on the Company's consolidated statements of cash flows.

Use of Estimates

In order to conform with U.S. GAAP, the Company is required to make certain estimates, judgments and assumptions when preparing its consolidated financial statements. These estimates, judgments and assumptions affect the reported assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reported periods. These estimates include, but are not limited to, the recoverability of creator signing fees and creator advances, the chargebacks and refunds reserve, the capitalization and estimated useful life of internal-use software, certain assumptions used in the valuation of equity awards, assumptions used in determining the fair value of business combinations, the allowance for doubtful accounts, indirect tax reserves and contra-revenue amounts related to fraudulent events, customer disputed transactions and refunds. The Company evaluates these estimates on an ongoing basis. Actual results could differ from those estimates and such differences could be material to the Company’s consolidated financial statements.

Comprehensive Loss

For all periods presented, comprehensive loss equaled net loss. Therefore, the condensed consolidated statements of comprehensive loss have been omitted from the unaudited condensed consolidated financial statements.

Segment Information

The Company’s Chief Executive Officer (CEO) is the chief operating decision maker. The Company's CEO reviews discrete financial information presented on a consolidated basis for purposes of allocating resources and evaluating the Company’s financial performance. Accordingly, the Company has determined that it operates as a single operating segment and has one reporting unit

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Topic 470) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Topic 815), which eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation.

The Company early adopted ASU 2020-06 on January 1, 2021 using the modified retrospective transition method. Adoption of ASU 2020-06 resulted in a decrease to additional paid-in capital of $45.5 million, an increase to retained earnings of $3.1 million, and a net increase to long-term debt of $42.4 million. Refer to Note 8 – Debt for more details. The Company will use the if-converted method to calculate diluted EPS unless it makes an irrevocable election to settle the principal of the notes in cash and the excess conversion spread in shares, in which case the Company can continue to use the Treasury stock method. Since the Company had a net loss for the three and nine months ended September 30, 2021 and 2020, the convertible senior notes were determined to be anti-dilutive and therefore had no impact to basic or diluted net loss per share for the period as a result of adopting ASU 2020-06.

The Company's significant accounting policies are discussed in the "Notes to Consolidated Financial Statements, Note 2. Significant Accounting Policies" in the 2020 Form 10-K. There have been no significant changes to these policies that have had a material impact on the Company's unaudited condensed consolidated financial statements and related notes, except as noted above.

Revenue Recognition

The Company derives its revenues primarily from ticketing and payment processing. The Company also derives a smaller portion of revenues from marketing services. The Company's customers are event creators who use the Company's platform to sell tickets and market events to attendees. Revenue is recognized when or as control of the promised goods or services is transferred to customers, in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services.

Transaction Revenue

For ticketing services, the Company's service provides a platform to the event creator and attendee to transact. The Company's performance obligation is to facilitate and process that transaction and issue the ticket, and revenue is recognized by the Company when the ticket is sold. The amount that the Company earns for its services is fixed which typically consists of a flat fee and a percentage based fee per ticket. As a result, the Company records revenue on a net basis related to its ticketing service fees.

For payment processing services, the Company's service provides the event creator with the choice of whether to use Eventbrite Payment Processing (EPP) or to use a third-party payment processor, referred to as Facilitated Payment Processing (FPP).

Under the EPP option, the Company is the merchant of record and is responsible for processing the transaction and collecting the face value of the ticket and all associated fees at the time the ticket is sold. The Company is also responsible for remitting these amounts collected, less the Company's fees, to the event creator. For EPP services, the Company determined that it is the principal in providing the service as the Company is responsible for fulfilling the promise to process the payment and has discretion in establishing the price of its service. As a result, the Company records revenue on a gross basis related to its EPP service fees. Costs incurred for processing the ticketing transactions are included in cost of net revenues in the consolidated statements of operations. Under the FPP option, the Company is not responsible for processing the transaction or collecting the face value of the ticket and associated fees. In this case, the Company records revenue on a net basis related to its FPP service fees.

Revenue is presented net of indirect taxes, customer refunds, payment chargebacks, estimated uncollectible amounts, creator royalties, and amortization of creator signing fees. Previously, the Company offered upfront payments to creators entering into new or renewed ticketing arrangements. However, the Company is shifting from upfront payment incentives to performance based incentives on a limited basis. See Note 4. Creator Signing Fees, Net, for further information relating to signing fees paid.

If an event is cancelled by a creator, then any obligations to provide refunds to event attendees are the responsibility of that creator. If a creator is unwilling or unable to fulfill their refund obligations, the Company may, at its discretion, provide attendee refunds.

Marketing Revenue

Revenue from marketing services is derived from providing creators with access to various marketing tools and functionalities for a monthly subscription fee. The Company considers that it satisfies its performance obligation as it provides the services to customers and recognizes revenue ratably over the service term which varies from one month to a year.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents includes bank deposits and money market funds held with financial institutions. Cash and cash equivalents balances include the face value of tickets sold on behalf of creators and their share of service charges, which are to be remitted to the creators. Such balances were $310.0 million and $181.1 million as of September 30, 2021 and December 31, 2020, respectively. Although creator cash is legally unrestricted, the Company does not utilize creator cash for its own financing or investing activities as the amounts are payable to creators on a regular basis. These amounts due to creators are included in accounts payable, creators on the consolidated balance sheets. The Company considers all highly liquid investments, including money market funds with an original maturity of three months or less at the date of purchase, to be cash equivalents.The Company has issued letters of credit under lease agreements and other agreements which have been collateralized with cash. This cash is classified as noncurrent restricted cash on the consolidated balance sheets.

Funds Receivable

Funds receivable represents cash-in-transit from third-party payment processors that is received by the Company within approximately five business days from the date of the underlying ticketing transaction. The funds receivable balances include the face value of tickets sold on behalf of creators and their share of service charges, which amounts are to be remitted to the creators.

Accounts Payable, Creators

Accounts payable, creators consists of unremitted ticket sale proceeds, net of Eventbrite service fees and applicable taxes. Amounts are remitted to creators within five business days subsequent to the completion of the related event. Creators may apply to receive a portion of these proceeds prior to completion of their events. For qualified creators, the Company passes ticket sales proceeds to the creator prior to the event, subject to certain limitations. Internally, the Company refers to these payments as advance payouts. When an advance payout is made, the Company reduces its cash and cash equivalents with a corresponding decrease to its accounts payable, creators.

Chargebacks and Refunds Reserve

The terms of the Company's standard merchant agreement obligate creators to reimburse attendees who are entitled to refunds. When the Company provides advance payouts, it assumes risk that the event may be cancelled, fraudulent or materially not as described, resulting in significant chargebacks and refund requests. If the creator is insolvent or has spent the proceeds of the ticket sales for event-related costs, the Company may not be able to recover its losses from these events, and such unrecoverable amounts could equal the value of the transaction or transactions settled to the creator prior to the event that is disputed, plus any associated chargeback fees not assumed by the creator. The Company records estimates for refunds and chargebacks of its fees as contra-revenue. The Company records estimates for losses related to chargebacks and refunds of the face value of tickets as an operating expense classified within sales, marketing and support. Reserves are recorded based on the Company's assessment of various factors, including the amounts paid and outstanding to creators in conjunction with the advance payout program, the size and nature of future events, the remaining time to event date, and actual chargeback and refund activity during the current year.

Impairment of Long-Lived Assets

The carrying amounts of long-lived assets, including property and equipment, capitalized internal-use software, acquired intangible assets and right-of-use operating lease assets are periodically reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful life is shorter than originally estimated. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to future undiscounted net cash flows the asset is expected to generate over its remaining life.

If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the revised shorter useful life.

Significant judgment and estimates are required in assessing impairment of long-lived assets, including identifying whether events or changes in circumstances require an impairment assessment, estimating future cash flows, and determining appropriate discount rates. As of September 30, 2021, management did not identify any events or changes in circumstances that would require an impairment assessment.

Fair Value Measurement

The Company measures its financial assets and liabilities at fair value at each reporting date using a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value:

Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 – Other inputs that are directly or indirectly observable in the marketplace.

Level 3 – Unobservable inputs that are supported by little or no market activity.

The Company’s cash equivalents, funds receivable, accounts receivable, accounts payable, funds payable and other current liabilities approximate their fair value. All such financial assets and liabilities are Level 1 and are measured at fair value on a recurring basis.
