Retirement Benefits [Abstract]
Employee Benefit Plans	13. Employee Benefit Plans We have a defined-contribution plan in the United States intended to qualify under Section 401 of the Internal Revenue Code, or the 401(k) Plan. The 401(k) Plan covers substantially all employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. We offer a safe harbor matching contribution in an amount equal to 100% of participating employee contributions to the plan up to 4% of the employee’s eligible compensation. During the years ended December 31, 2023, 2022, and 2021, we recorded $1.5 million, $1.1 million, and $0.8 million, respectively, of expenses related to the 401(k) plan. Israeli Severance Pay Pursuant to Israel’s Severance Pay Law, Israeli employees are entitled to severance pay equal to one month’s salary for each year of employment, or a portion thereof. We have elected to include our employees in Israel under Section 14 of the Severance Pay Law, under which these employees are entitled only to monthly deposits made in their name with insurance companies, at a rate of 8.33% of their monthly salary. These payments release us from any future obligation under the Israeli Severance Pay Law to make severance payments in respect of those employees; therefore, any liability for severance pay due to these employees, and the deposits under Section 14 are not recorded as an asset in the consolidated balance sheets. During the years ended December 31, 2023, 2022, and 2021, we recorded $4.2 million, $4.5 million, and $3.8 million, respectively, in severance expenses related to these employees.

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, and include the accounts of Riskified Ltd. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Immaterial Prior Period Error Correction

During the year ended December 31, 2023, we identified an immaterial error relating to the period over which certain sales commissions were amortized. We assessed the materiality of the error on the financial statements for prior years individually and in the aggregate, and concluded that it was not material to any previously issued consolidated financial statements. We corrected the error by revising the consolidated financial statements appearing herein. The impact of the errors on the Company’s consolidated balance sheet as of January 1, 2021 was an overstatement of deferred contract acquisition costs of $0.7 million and an understatement of accumulated deficit of $0.7 million. There was no impact of the error on the consolidated statements of cash flows for the periods presented.

The following tables summarize the effects of the corrections on the Company’s consolidated financial statements for the years ended December 31, 2022 and 2021:

Initial Public Offering

On August 2, 2021, we completed our initial public offering (“IPO”), in which we issued and sold 19,925,000 shares of our Class A ordinary shares at an offering price of $21.00 per share, including 2,625,000 shares of our Class A ordinary shares pursuant to the exercise in full of the underwriters’ option to purchase additional shares. We received net proceeds of $386.6 million after deducting underwriting discounts and commissions of $26.2 million, and other issuance costs of $5.7 million.

Immediately prior to the closing of the IPO, 962,940 shares of Series E-1 convertible preferred shares were issued upon the exercise of the Series E-1 convertible preferred share warrants. In addition, all convertible preferred shares then outstanding automatically converted into 32,291,470 shares of our Class A ordinary shares.

Prior to the IPO, deferred offering costs, which consist primarily of accounting, legal and other fees related to our IPO, were capitalized within other assets, noncurrent in the consolidated balance sheets. Upon the consummation of the IPO, $5.7 million of deferred offering costs were reclassified into shareholders’ equity as an offset against IPO proceeds.

Recapitalization

On July 28, 2021, we adopted new Articles of Association (“AoA”), in which, among other things, we implemented, upon the closing of the IPO:

(i) a dual class ordinary share structure pursuant to which we have two classes of ordinary shares: Class A ordinary shares and Class B ordinary shares. The rights of the holders of our Class A ordinary shares and Class B ordinary shares are identical, except with respect to voting, conversion and transfer rights. Class A ordinary shareholders are entitled to one vote per share and Class B ordinary shareholders are entitled to ten votes per share. The dual class ordinary share structure concentrates voting power with our pre-IPO shareholders. Holders of Class A ordinary shares and Class B ordinary shares will vote together as a single class on all matters (including the election of directors) submitted to a vote of our shareholders, unless otherwise required by law or our amended and restated articles of association;

(ii) the elimination of the par value per ordinary share; and

(iii) a two-for-one reverse share split of our Class A ordinary shares (the “Reverse Share Split”).

Immediately after the effectiveness of the Reverse Share Split, we issued and distributed Class B ordinary shares to holders of the Class A ordinary shares on a two-for-one ratio, such that each holder of Class A ordinary shares received two Class B ordinary shares for each Class A ordinary share (the “Additional Class B Issuance”).

The historical financial statements have not been retroactively adjusted for the (i) dual class structure, (ii) elimination of par value, and (iii) Additional Class B Issuance. As a result, all information associated with these items related to our ordinary shares and their associated par value, convertible preferred shares and their associated par value, share options, restricted share units (“RSUs”), and warrants to purchase convertible preferred shares are being presented prospectively.

All information related to our ordinary shares and their associated par value, convertible preferred shares and their associated par value, share options, RSUs, and warrants to purchase convertible preferred shares have been retroactively adjusted to give effect to the Reverse Share Split for all periods presented.

Treasury Shares

In August 2023, the board of directors authorized the Company to repurchase up to $75.0 million of its Class A ordinary shares (the “Repurchase Program”). Costs associated with the acquisition of Class A ordinary shares are presented as Treasury Shares on the consolidated balance sheet as a reduction of shareholders' equity. Refer to Note 10 for more information on the Repurchase Program.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Actual results could differ materially from these estimates. On an ongoing basis, we evaluate our estimates, including those related to the estimated period of benefit on deferred contract costs, the capitalization of certain costs to fulfill a contract, the allowance for credit losses, the fair value of financial assets and liabilities including the fair value of derivatives and investments, the useful lives of property and equipment, capitalization and estimated useful life of internal-use software, share-based compensation including the determination of the fair value of our ordinary shares (prior to IPO), the fair value of indemnification guarantees and the associated systematic and rational amortization method, provisions for chargebacks, the fair value of convertible preferred share warrant liabilities and convertible preferred share tranche rights (prior to IPO), incremental borrowing rate (“IBR”) used for operating lease right-of-use (“ROU”) assets and operating lease liabilities, and the valuation of deferred tax assets and uncertain tax positions. We base our estimates on assumptions, both historical and forward-looking, trends, and various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.

Foreign Currency

The U.S. dollar is our functional currency and the functional currency of a majority of our subsidiaries.

For the subsidiaries where the U.S. dollar is the functional currency, monetary assets and liabilities denominated in currencies other than the U.S. dollar are remeasured into U.S. dollars at exchange rates in effect at the end of each period. Foreign currency transaction gains and losses from these remeasurements are recognized in other income (expense), net, within the consolidated statements of operations. Foreign currency transactions resulted in net gains of $1.4 million, $2.5 million, and $0.2 million for the years ended December 31, 2023, 2022, and 2021, respectively.

For subsidiaries where the functional currency is not the U.S. dollar, we use the period-end exchange rates to translate assets and liabilities, the average monthly exchange rates to translate revenue and expenses, and historical exchange rates to translate shareholders’ equity, into U.S. dollars. We record translation gains and losses in accumulated other comprehensive profit (loss) as a component of shareholders’ equity in the consolidated balance sheets.

Concentration of Risks

Our financial instruments that are exposed to concentrations of credit risk primarily consist of cash and cash equivalents, restricted cash, short-term deposits, short-term investments, accounts receivable and derivative financial instruments. We maintain our cash, cash equivalents, restricted cash, short-term deposits, and short-term investments with high-quality financial institutions mainly in the United States and Israel, the composition of which are regularly monitored by us. We have not experienced any material losses in such accounts. Our derivatives expose us to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. We seek to mitigate such risk by limiting our counterparties to major financial institutions and by spreading the risk across a number of major financial institutions. In addition, the potential risk of loss with any one counterparty resulting from this type of credit risk is monitored on an ongoing basis.

Our customers are online merchants. For accounts receivable, we are exposed to credit risk in the event of nonpayment by online merchants to the extent the amounts are recorded in the consolidated balance sheets. We extend different levels of credit to online merchants and maintain reserves for potential credit losses based upon the expected collectability of accounts receivable. We manage credit risk related to our merchants by performing periodic evaluations of credit worthiness and consumer indebtedness and applying other credit risk monitoring procedures.

The following table summarize our merchants that represented 10% or more of Accounts receivable and Revenue:


	Accounts Receivable				Revenue
	As of December 31,				Year Ended December 31,
	2023		2022		2023		2022		2021
Customer A	17	%	22	%	11	%	13	%	16	%
Customer B	11	%	*		*		*		*

________________

*Represents less than 10%

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents consist of cash in banks, bank deposits, and money market funds. We consider all highly liquid investments, with an original maturity of three months or less at the date of purchase, to be cash equivalents. Our restricted cash primarily consisted of cash deposits to back letters of credit related to certain operating leases.

Short-Term Deposits

Short-term deposits consist of bank deposits with original maturities between 4 and 12 months and that mature within 12 months of the balance sheet date. Short-term deposits are reported at cost.

Short-Term Investments

Short-term investments consist of marketable debt securities that we have classified and accounted for as available-for-sale. We determine the appropriate classification of our investments in marketable debt securities at the time of purchase and reevaluate such designation at each balance sheet date. After consideration of our risk versus reward objectives, as well as our liquidity requirements, we may sell these debt securities prior to their effective maturities. As a result, we classify our investments, including those with maturities beyond 12 months, as current assets in the Consolidated Balance Sheets. We carry these securities at fair value, and report the unrealized gains and losses, net of taxes, as a component of shareholders’ equity, except for changes in allowance for expected credit losses, which is recorded in other income (expense), net, within the consolidated statements of operations. We periodically evaluate our available-for-sale debt securities for impairment. If the amortized cost of an individual security exceeds its fair value, we consider our intent to sell the security or whether it is more likely than not that we will be required to sell the security before recovery of its amortized basis. If either of these criteria are

met, we write down the security to its fair value and record the impairment charge in other income (expense), net within the consolidated statements of operations. If neither of these criteria are met, we determine whether credit loss exists. Credit loss is estimated by considering changes to the rating of the security by a rating agency, any adverse conditions specifically related to the security, as well as other factors.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We measure financial assets and liabilities at fair value for each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs. 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 – Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Financial instruments consist of cash and cash equivalents, restricted cash, short-term deposits, short-term investments, accounts receivables, derivative financial instruments, accounts payables, accrued liabilities, indemnification guarantees. Cash and cash equivalents, short-term deposits, restricted cash, accounts receivable, accounts payable, and accrued liabilities are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment date. Short-term investments and derivative financial instruments are stated at fair value on a recurring basis as disclosed in Note 4 below.

We record indemnification guarantees that we issue upon approving a transaction at fair value when issued using the income approach. To measure this guarantee, we consider the premium that would have been received for the same guarantee if it were issued in a stand-alone transaction. The fair value of these indemnification guarantees is determined based on historical chargeback claims, a risk premium fee that would be required for a third party to assume this liability, and an appropriate discount rate due to the time period between issuance of the guarantee and settlement or expiration. Historical chargeback guarantee claims are not readily observable in the marketplace and are generally classified as Level 3 inputs. Indemnification guarantees are recorded at fair value when issued and not remeasured to fair value each period. Refer to Note 8 below for more information regarding indemnification guarantees.

Because of the inherent uncertainty of valuation, the estimated fair value of our financial instruments, in particular our indemnification guarantees, may differ significantly from the values that would have been used had a ready market for the financial instruments existed, and the differences could be material to our consolidated financial statements. Refer to Item 5. “Operating and Financial Review and Prospects — Critical Accounting Policies and Estimates.”

Accounts Receivable, Net

Accounts receivable are recorded at the invoiced amount, net of an allowance for credit losses. The allowance for credit losses is based on our assessment of the collectability of accounts. We regularly review the adequacy of the allowance for credit losses based on a combination of factors, including an assessment of the current merchant’s credit worthiness, the age of the balance, the nature and size of the merchant, the financial condition of the merchant, and the amount of any receivables in dispute. Accounts

receivable deemed uncollectible are charged against the allowance for credit losses when identified. The allowance for doubtful accounts was $0.5 million and $0.5 million as of December 31, 2023 and 2022, respectively.

The following table represents a roll-forward of the allowance for credit losses:


	Year Ended December 31,
	2023
	(in thousands)
Beginning balance	$	487
Current period provision	198
Uncollectible accounts charged against the allowance	(170)
Recoveries of amounts previously deemed uncollectible	—
Ending balance	$	515

Derivative Financial Instruments

We enter into derivative instruments to manage risks relating to our ongoing business operations. We enter into foreign currency forward and option contracts with financial institutions to protect against foreign exchange risks attributable to our exposure to changes in the exchange rates of (a) the New Israeli Shekel (“NIS”) against the U.S. dollar and (b) the Euro against the U.S. dollar. Our primary objective in entering into these contracts is to reduce the volatility of forecasted earnings and cash flows associated with changes in foreign currency exchange rates. We do not use derivative instruments for trading or speculative purposes.

We account for our derivative instruments as either assets or liabilities and carry them at fair value. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. Derivative instruments are recorded as either prepaid expenses and other current assets or accrued expenses and other current liabilities in the consolidated balance sheets. We record changes in the fair value of derivative instruments that are designated as hedging instruments in accumulated other comprehensive profit (loss) in the consolidated balance sheets, until the forecasted transaction occurs upon which we reclassify the related gain or loss on the derivative to the same financial statement line item in the consolidated statements of operations to which the derivative relates.

Other derivatives not designated as hedging instruments consist primarily of foreign currency forward contracts that we use to hedge monetary assets or liabilities denominated in currencies other than the functional currency of a subsidiary. Changes in the fair value on these contracts, as well as the related costs, are recognized in Other income (expense), net, along with the foreign currency gains and losses on the related monetary assets and liabilities. Refer to Note 5 for additional information.

Property and Equipment, Net

Property and equipment are stated at cost net of accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line method over the estimated useful lives of the respective assets. Expenditures for maintenance and repairs are expensed as incurred.

The estimated useful lives of our property and equipment are as follows:


Computer equipment			3 years
Furniture and office equipment			7 years
Leasehold improvements			Shorter of remaining lease term or estimated useful life

Capitalized Software Costs

Costs related to software acquired, developed, or modified solely to meet our internal requirements, with no substantive plans to market such software at the time of development are capitalized. Costs incurred during the preliminary project stage and during the post implementation operational stage are expensed as incurred. Eligible costs incurred during the application development stage of the project are capitalized. Capitalized software development costs are recorded as part of other assets, noncurrent in the consolidated balance sheets. Maintenance costs are expensed as incurred. Capitalized software development costs are amortized on a straight-line basis over the software’s estimated useful life, which is four years and are recorded in cost of revenue in the consolidated statements of operations. As of December 31, 2023 and 2022, we have capitalized $3.5 million, net and $5.0 million, net, respectively, of qualifying software development costs. Amortization expenses related to capitalized software costs were $1.5 million, $0.7 million, and $0.4 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Cloud Computing Arrangement Implementation Costs

We capitalize certain implementation costs incurred in a cloud computing arrangement during the application development stage pursuant to Accounting Standards Codification, or ASC, 350-40, Internal Use Software. These costs are amortized over the term of the hosting arrangement on a straight-line basis, and are included within operating expenses in the consolidated statements of operations. Costs incurred in the preliminary stages of development are analogous to research and development activities and are expensed as incurred. These capitalized costs are included in other assets, noncurrent in the consolidated balance sheets. We have capitalized $0.7 million and $0.2 million of qualifying cloud computing arrangement implementation costs as of December 31, 2023 and 2022, respectively. Amortization expenses related to capitalized cloud computing arrangement implementation costs were $0.2 million, $0.2 million, and $0.2 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Leases

Our lease accounting policy under ASC Topic 840, “Leases” until January 1, 2022, prior to the adoption of the new lease guidance was as follows:

Leases are reviewed and classified as either capital or operating leases at their inception. In certain lease agreements, we may receive renewal or expansion options, rent holidays, and other incentives. For operating leases, we recognize lease costs on a straight-line basis once we take control of the space, without regard to deferred payment terms such as rent holidays that defer the commencement date of required payments. Additionally, incentives received are treated as a reduction of costs over the term of the agreement.

On January 1, 2022, we adopted the new lease guidance for our operating lease agreements. Refer to Note 7 below for additional information. Our lease accounting policy under ASC Topic 842, “ASC 842” from January 1, 2022, following the adoption of the new lease guidance is as follows:

We determine if an arrangement meets the definition of a lease at the inception of the lease, and leases are classified at commencement as either operating or finance leases. We do not have any finance leases. Operating lease ROU assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease agreement. Operating lease ROU assets are measured based on the discounted present value of the remaining lease payments, initial direct costs incurred and prepaid lease payments, excluding lease incentives received prior to lease commencement. Operating lease liabilities are measured based on the discounted present value of the remaining lease payments. The discounted present value of remaining lease payments is computed using our IBR based on the information available at the commencement date of the lease as our leases generally do not provide an implicit rate. Our IBR was estimated to

approximate the interest rate for collateralized borrowing with similar terms and payments and in economic environments where the leased asset was located.

The lease term may include options to extend or terminate the lease when it is reasonably certain that we would exercise that option. We made an accounting policy election for lease agreements with a term of 12 months or less and do not recognize operating lease ROU assets and operating lease liabilities in respect of those agreements. Payments under our lease agreements are primarily fixed; however, certain lease agreements contain variable payments, which are expensed as incurred and not included in the operating lease ROU assets and operating lease liabilities. Variable lease payments are mainly comprised of common area maintenance, utilities, real estate taxes, and payments affected by changes in indexes.

We elected the practical expedient to not separate lease and non-lease components for our leases.

We sublease certain office spaces to third parties. Operating sublease income is recognized on a straight-line basis over the term of the agreement.

Impairment of Long-Lived Assets

We evaluate the recoverability of long-lived assets, including property and equipment, for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be fully recoverable. Such events and changes may include significant changes in performance relative to expected operating results, significant changes in asset use, significant negative industry or economic trends, and changes in our business strategy. Recoverability of these assets is measured by comparing the carrying amounts with the future undiscounted cash flows that the assets are expected to generate. If such review indicates that the carrying amount of long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair value. We determined that there were no material events or changes in circumstances that indicated that our long-lived assets were impaired during the periods presented.

Indemnification Guarantees

We provide contractual assurances around the accuracy of our approvals so that our merchants can confidently automate a transaction’s execution. Our contracts obligate us to stand ready to indemnify our merchants for any costs incurred from a chargeback due to fraud (i.e., the “guarantee obligation”). Accordingly, we account for the guarantee obligation as an indemnification under the general provisions of ASC 460, Guarantees, or ASC 460, and recognize a liability at fair value upon approving a transaction at an amount that represents what we would need to pay a third party to relieve ourselves from this obligation. This liability is presented as Guarantee obligations on the consolidated balance sheets and will be released to revenue in the consolidated statements of operations.

We are relieved from our guarantee obligation at the earlier of (a) paying a chargeback or (b) expiration of the guarantee which is generally six months from the date of the transaction. We recognize the guarantee obligation as revenue through a systematic and rational amortization method over a six-month period that is representative of our historical pattern of being released from risk under the guarantee obligation.

While no individual transaction is probable of a chargeback occurring, when we analyze a portfolio of transactions, if we believe a future chargeback is probable and reasonably estimated, we accrue a liability and an associated expense through cost of revenue in accordance with ASC 450, Contingencies, or ASC 450. Inputs and assumptions used by management to calculate this provision are based on the transactions approved and the features of those transactions as well as historical information about chargebacks. It is possible that the estimate may change in the near term, and the effect of the change could be material. These liabilities are recorded within Provision for chargebacks, net on the consolidated balance sheets and will be reduced by credits issued or cash paid to merchants. Refer to Note 8 below or

Item 5. “Operating and Financial Review and Prospects — Critical Accounting Policies and Estimates” for additional information.

Ordinary Share Warrants

Prior to IPO, warrants to purchase our Series B/C and E-1 convertible preferred shares were recorded as a liability at fair value on our consolidated balance sheets as the underlying convertible preferred shares were contingently redeemable, upon a deemed liquidation event that is outside of our control, and therefore could have obligated us to transfer assets.

The Series B/C convertible preferred share warrants were remeasured to fair value at the end of each reporting period with changes in fair value recognized as a gain or loss within other income (expense), net in the consolidated statements of operations until the earlier of the exercise of the warrants, the expiration of the warrants, or upon the completion of a qualified IPO. Upon IPO, the Series B/C convertible preferred share warrants were converted to warrants to purchase ordinary shares, and the then outstanding liability was reclassified to additional paid-in capital in the consolidated balance sheets. The warrants to purchase ordinary shares may be exercised any time prior to, and shall expire upon, the earlier of (a) April 29, 2025 or (b) immediately prior to the consummation of certain deemed liquidation events. In November 2023, the outstanding warrants to purchase ordinary shares were exercised. Refer to Note 9.

The Series E-1 convertible preferred share warrants were remeasured to fair value at the end of each reporting period with changes in fair value recognized as a gain or loss within other income (expense), net in the consolidated statements of operations until the earlier of the exercise of the warrants, the expiration of the warrants, or the completion of a deemed liquidation event, including a qualified IPO. Upon IPO, the Series E-1 convertible preferred share warrants were automatically exercised.

In conjunction with a SaaS Agreement entered into in 2021, we issued a warrant to a customer to purchase ordinary shares. The warrant vests annually, in equal amounts, over a five-year period commencing on the effective date of the SaaS Agreement. The warrant is accounted for as consideration payable to a customer under ASC 606 and will reduce revenue as we recognize revenue under the SaaS Agreement over a period of five years. As of December 31, 2023, the warrant is outstanding.

Revenue Recognition

We primarily generate revenue by granting merchants access to our eCommerce risk intelligence platform and reviewing and approving eCommerce transactions for legitimacy. Revenue is also generated from the issuance of indemnification guarantees as noted above within “Indemnification Guarantees”. For the majority of our revenue, merchants pay us a percentage of every dollar of the gross merchandise volume, or GMV, that we approve and guarantee on their behalf. Our fee, as determined by our risk-based pricing model, in these situations is a percentage of the GMV of our merchants’ orders that we approve, prior to taxes or other charges. These arrangements do not provide merchants with the right to take possession of our software platform. Rather, merchants are granted continuous access to our software platform under a hosting arrangement over the contractual period.

As noted above within “Indemnification Guarantees”, our contracts with our merchants obligate us to review eCommerce transactions for legitimacy as well as to stand ready to indemnify merchants for costs incurred associated with an approved transaction in the event of a chargeback due to fraud. Our fee is allocated between the consideration owed to us for our fraud review service performance obligation accounted for under ASC 606 and the consideration owed to us for issuing indemnification guarantees that are accounted for under ASC 460 and are recorded at fair value. Consideration allocated to fraud review is recognized as revenue over the contract period in the month that the transactions are approved while consideration allocated to the indemnification guarantee is recognized as we are released from risk under the guarantee, generally over a six-month period from the date of the transaction.

We present revenue net of cancellations and adjustments for minimum service level agreements.

In accordance with ASC 606, revenue is recognized when a customer obtains control of promised products. The amount of revenue recognized reflects the consideration that we expect to receive in exchange for these products. To achieve the core principle of this standard, we applied the following five steps:

1.Identification of the contract, or contracts, with the merchant

We determine that we have a contract with a merchant when the contract is approved, each party’s rights and obligations regarding the products to be transferred can be identified, the payment terms for the products can be identified, we have determined the merchant has the ability and intent to pay, and the contract has commercial substance. At contract inception, we evaluate whether two or more contracts should be combined and accounted for as a single contract and whether the combined or single contract includes more than one performance obligation. Contracts with our merchants are typically for a period of one year.

2.Identification of the performance obligations in the contract

Performance obligations promised in a contract are identified based on the products that will be transferred to the merchant that are both capable of being distinct, whereby the merchant can benefit from the products either on their own or together with other resources that are readily available from third parties or from us, and are distinct in the context of the contract, whereby the transfer of the products is separately identifiable from other promises in the contract.

For SaaS arrangements, we provide access to our cloud-hosted software platform and reviewing and approving eCommerce transaction for legitimacy, without providing the merchant the right to take possession of our software, which we consider to be a single performance obligation. Revenue generated from the issuance of indemnification guarantees is accounted for under ASC 460. Refer to “Indemnification Guarantees” above and Note 8 below for additional information.

3.Determination of the transaction price

As our contracts include an unknown quantity of approved transactions at a fixed contractual rate per approved transaction value executed on a monthly basis, the contract price is deemed variable. We allocate the variable consideration to the month in which we have the contractual right to bill under the contract as this represents the amount of consideration to which we expect to be entitled for the transfer of products during that month. Certain of our contracts include additional forms of variable consideration such as service level commitments relating to uptime availability and minimum approval rates as well as provisions that provide for reimbursements should our merchant’s consumer cancel an approved order. If we fail to meet these commitments, merchants are generally permitted to receive a refund in the form of a credit on their invoice. Under certain arrangements, when the merchant’s consumer cancels an order that we have approved, we provide a refund of some or all of the fees owed by our merchant to us generally in the form of a credit on our merchant’s invoice. The transaction price is reduced to reflect our estimate of the amount of consideration to which we are entitled based on the terms of the contract.

Payment terms and conditions vary by contract type, although terms generally include a requirement to pay within 30 days. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined that our contracts do not include a significant financing component. The primary purpose of our invoicing terms is to provide our merchants with simplified and predictable ways of purchasing our products; not to receive financing from our merchants or to provide merchants with financing. We applied the practical expedient in ASC 606 and did not evaluate payment terms of one year or less for the existence of a significant financing component. Revenue is recognized net of any taxes collected from merchants (e.g., sales tax and other indirect taxes), which are subsequently remitted to governmental entities. We generally do not offer a right of refund in our contracts.

4.Allocation of the transaction price to the performance obligations in the contract

Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on each performance obligation’s relative standalone selling price. Access to our cloud-hosted software is considered one performance obligation in the context of the contract and accordingly the transaction price is allocated to this single performance obligation.

5.Recognition of the revenue when, or as, a performance obligation is satisfied

Revenue is recognized at the time the related performance obligation is satisfied by transferring control of the promised service to the customer. Revenue is recognized in an amount that reflects the consideration that we expect to receive in exchange for those products. For SaaS arrangements, we have determined that these arrangements meet the variable consideration allocation exception and revenue is recognized over the contract period in the month that the transactions are approved.

Contract Balances

Contract assets consist of unbilled accounts receivable. The terms of our agreements are monthly, annual, or multi-year, and we typically invoice our merchants based on monthly usage. In some arrangements, a right to consideration for our performance under the merchant contract may occur before invoicing to the merchant, resulting in an unbilled accounts receivable. The amount of unbilled accounts receivable included within accounts receivable, net on the consolidated balance sheets was immaterial for the periods presented.

Cost to Obtain a Contract

We capitalize sales commissions and associated payroll taxes paid that are incremental to the acquisition of merchant contracts. These costs are recorded as Deferred contract acquisition costs on the consolidated balance sheets. We determine whether costs should be deferred based on our sales compensation plans and if the commissions are incremental and would not have occurred absent the merchant contract. Determining whether such costs are incremental to obtaining the online merchant contract requires a certain degree of judgment.

Sales commissions for initial contracts are amortized on a straight-line basis over an estimated period of benefit of four years. We determine the period of benefit for sales commissions by taking into consideration the estimated customer life, technological life of our software, and other factors. These factors involved in the determination of the period of benefit include inherent uncertainties and the application of significant judgment. Sales commissions for renewal contracts are not commensurate with sales commissions for initial contracts and are deferred and then amortized on a straight-line basis over the contractual term.

Sales commissions expenses are included in sales and marketing expense in the consolidated statements of operations. We periodically review these deferred contract acquisition costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit. There were no impairment losses recorded during the periods presented.

Cost to Fulfill a Contract

We capitalize payroll related costs of certain integration services required in order to be able to fulfill the obligation to provide our products to our merchants. Integration services are promises that are not capable of being distinct. These costs are capitalized to the extent they are directly related to a contract, are recoverable, and generate or enhance resources that will be used in delivering our SaaS products. These costs are recorded as deferred contract fulfillment costs in other assets, noncurrent on the consolidated balance sheets.

Capitalized costs to fulfill a contract are amortized on a straight-line basis over the expected period of benefit of four years and are included in cost of revenue in the consolidated statements of operations. We

determine the period of benefit by taking into consideration the estimated customer life, technological life of our software, and other factors. These factors involved in the determination of period of benefit involve inherent uncertainties and the application of significant judgment. We periodically review these deferred contract fulfillment costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit. There were no impairment losses recorded during the periods presented.

Cost of Revenue

Cost of revenue primarily consist of chargeback expenses, net of chargebacks won, and other expenses related to providing our products to our merchants. These other expenses include compensation and benefits related costs, including share-based compensation expense associated with teams integral in providing our service, hosting fees and software costs, payment processing fees, amortization of capitalized software development costs and deferred contract fulfillment costs, depreciation expense, and allocated overhead.

Chargeback claims can be disputed and if the decision of the dispute concludes that the order was legitimate and not fraudulent, the chargeback is classified as chargeback won. We present chargeback expenses net of chargebacks won, since such amounts are refunded to us. Amounts for chargebacks won were $25.0 million, $20.3 million, and $14.3 million for the years ended December 31, 2023, 2022, and 2021, respectively.

Research and Development

Research and development costs primarily consist of compensation and benefits related costs, including share-based compensation expense associated with research and development teams that are responsible for the design, development, and testing of our ecommerce risk intelligence platform infrastructure including expenses associated with adding new features, increasing the functionality, and enhancing the usability of our platform. Research and development costs also consist of third-party software hosting fees used by our research and development teams, depreciation expense, and allocated overhead. Research and development costs are expensed as incurred.

Sales and Marketing

Sales and marketing costs primarily consist of compensation and benefits related costs, including share-based compensation expense directly associated with our sales and marketing teams. Sales and marketing costs also consists of costs associated with conferences, events, digital marketing and advertising programs, deferred contract acquisition costs, depreciation expense, and allocated overhead. Sales and marketing costs are expensed as incurred.

Digital marketing programs include advertising, promotional events, and brand-building activities. Advertising costs are expensed as incurred and were $4.9 million, $6.0 million, and $5.2 million for the years ended December 31, 2023, 2022, and 2021, respectively.

General and Administrative

General and administrative costs primarily consist of compensation and benefits related costs, including share-based compensation expense associated with our finance, legal, human resources, information technology and administrative functions. General and administrative costs also consist of third-party professional service fees for external legal, accounting and other consulting services, depreciation expense, and allocated overhead. General and administrative costs are expensed as incurred.

Share-Based Compensation

Share-based compensation expense related to share-based awards is recognized based on the fair value of the awards granted. The fair value of each share option award is estimated on the grant date

using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the input of highly subjective assumptions, including the fair value of the underlying ordinary shares, the expected term of the share option, the expected volatility of the price of our ordinary shares, risk-free interest rates, and the expected dividend yield of ordinary shares. The assumptions used to determine the fair value of the option awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. The related share-based compensation expense is recognized on a straight-line basis over the requisite service period of the awards, including awards with graded vesting and no additional conditions for vesting other than service conditions. Forfeitures are accounted for as they occur.

We have granted to employees, RSUs, that vest either upon the (a) satisfaction of service-based vesting conditions only and (b) satisfaction of both service-based and performance-based vesting conditions. The fair value of each RSU award is based on the fair value of the underlying ordinary shares as of the grant date. We have also granted to our Chief Executive Officer (“CEO”), RSUs, that vest upon the satisfaction of service-based, performance-based, and market-based vesting conditions. A Monte-Carlo simulation model was used to determine the grant date fair value by simulating a range of scenarios with each outcome resulting in a determined value. The grant date fair value of this award is the average of the values determined by each simulation. The simulation was also used to derive the requisite service period.

For RSU awards with both service-based and performance-based vesting conditions, the service-based vesting condition has varying terms, but is generally satisfied over four to five years. The performance-based vesting condition is satisfied upon the occurrence of a qualifying liquidation event which is defined as the earlier to occur of (i) the six month anniversary of or, if earlier, March 15 of the year following, the occurrence of an IPO or (ii) consummation of a merger and acquisition, or M&A, transaction of the Company. The performance-based vesting condition underlying these awards was satisfied upon our IPO. The market-based condition underlying the CEO RSU is satisfied upon the trading price of our ordinary shares meeting certain thresholds.

RSU awards with service-based vesting conditions only are recognized using the straight-line method. RSU awards with more than just a service-based vesting condition are recognized using the accelerated attribution method once the performance-based vesting condition is probable of occurring which results in higher expenses attributed to the earlier periods of the requisite service period.

Income Taxes

We are subject to income taxes in Israel, the United States, and other jurisdictions. These other jurisdictions may have different statutory rates than in Israel. Income taxes are accounted for in accordance with ASC 740, Income Taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statements carrying amounts of existing assets and liabilities and their respective tax basis as well as operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Valuation allowances are provided when necessary to reduce deferred tax assets to an amount that is more likely than not to be realized.

We recognize income tax benefits from uncertain tax positions only if we believe that it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such uncertain tax positions are then measured based on the largest benefit that is more likely than not to be realized upon the ultimate settlement.

Net Profit (Loss) Per Share Attributable to Ordinary Shareholders

We compute net profit (loss) per share using the two-class method required for participating securities. The two-class method requires income available to ordinary shareholders for the period to be

allocated between ordinary shares and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. Under the two-class method, we allocate earnings proportionately to Class A and B ordinary shares outstanding for the period. Prior to IPO, we considered our convertible preferred shares to be participating securities as the holders of the convertible preferred shares would be entitled to dividends in preference to ordinary shareholders. These participating securities do not contractually require the holders of such shares to participate in our losses. As such, net loss for the periods presented was not allocated to our participating securities.

Our basic net profit (loss) per share is calculated by dividing net profit (loss) attributable to ordinary shareholders by the weighted-average number of ordinary shares outstanding for the period, without consideration of potentially dilutive securities. The diluted net profit (loss) per share is calculated by giving effect to all potentially dilutive securities outstanding for the period using the treasury stock method or the if-converted method based on the nature of such securities. Diluted net profit (loss) per share is the same as basic net profit (loss) per share in periods when the effects of potentially dilutive shares of ordinary shares are anti-dilutive.

Segment Information

We operate our business in one operating segment and therefore have one reportable segment. Operating segments are defined as components of an entity that engage in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker, who is our CEO, in deciding how to allocate resources and assess performance. Our chief operating decision maker allocates resources and assesses performance based upon discrete financial information at the consolidated level.

Revenue by geographical region can be found in the revenue recognition disclosures in Note 3 below. Property and equipment, net of depreciation and amortization, by geographic region can be found in Note 6 below. Operating lease ROU assets by geographic region can be found in Note 7 below.

Recently Adopted Accounting Pronouncements

As an emerging growth company, or EGC, the Jumpstart Our Business Startups Act, or the JOBS Act, allows us to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The JOBS Act does not preclude an EGC from early adopting new or revised accounting standards. We have elected to use extended transition periods permissible under the JOBS Act while also early adopting certain accounting pronouncements. The adoption dates discussed below reflect these elections.

In June 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, including subsequent amendments thereafter, which established ASC 326. ASC 326 replaces the existing incurred loss impairment model with a current expected credit loss model that requires more timely recognition of estimated expected credit losses over the life of certain financial instruments. Our accounts receivable and available-for-sale debt securities are in the scope of ASC 326. We adopted ASC 326 as of January 1, 2023. The adoption of ASC 326 did not have a material impact on our financial condition and results of operations within our consolidated financial statements.

Recently Issued Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (FASB) issued ASU No. 2023-07, Reportable Segments (Topic 280): Improvements to Reportable Segment Disclosures, which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses, including public entities with a single operating or reportable segment. The updated standard will be effective for annual periods beginning in fiscal 2024 and interim periods beginning in the first quarter of fiscal 2025. Early adoption is permitted. We are currently evaluating the impact of this standard on our financial statement disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands disclosures in an entity’s income tax rate reconciliation table and regarding cash taxes paid both in the U.S. and foreign jurisdictions. The updated standard will be effective for annual periods beginning in fiscal 2026. We are currently evaluating the impact of this standard on our financial statement disclosures.

Guarantees, Commitments, and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Guarantees, Commitments, and Contingencies

8. Guarantees, Commitments, and Contingencies

Indemnification Guarantees

We provide contractual assurances around the accuracy of our approvals so that our merchants can confidently automate a transaction’s execution. Our contracts obligate us to stand ready to indemnify our merchants for any costs incurred from a chargeback due to fraud. Accordingly, we account for the guarantee obligation as an indemnification under the general provisions of ASC 460 and recognize a liability at fair value upon approving a transaction at an amount that represents what we would need to pay a third party to relieve ourselves from this obligation. This liability is presented as Guarantee obligations on the consolidated balance sheets and was $12.7 million and $12.4 million as of December 31, 2023 and 2022, respectively, and will be released to revenue in the consolidated statements of operations.

Our provision for chargebacks includes amounts associated with chargebacks that have been submitted and accepted but not yet paid by us as of the balance sheet date as well as estimates of chargebacks that have not yet been submitted and accepted relating to approved transactions that are

accounted for under ASC 450, Contingencies. While no individual transaction is probable of a chargeback occurring, when we analyze a portfolio of transactions, if we believe a future chargeback is probable and reasonably estimated, we accrue a liability and an associated expense through cost of revenue. Inputs and assumptions used by management to calculate the provision are based on the transactions approved and the features of those transactions as well as historical information about chargebacks. It is possible that the estimate may change in the near term, and the effect of the change could be material. Provision for chargebacks, net on the consolidated balance sheets were $12.1 million and $12.0 million as of December 31, 2023 and 2022, respectively, and will be reduced by credits issued or cash paid to merchants.

As of December 31, 2023, our portfolio of potential chargeback liabilities was diversified across numerous industries, hundreds of merchants, and millions of individual transactions. The maximum potential payment to our merchants for these guarantees at a point in time, if every order we approved was fraudulent, is generally the aggregate approved transaction amount excluding cancelled orders, orders that have expired guarantees, and orders for which guarantees have already been paid. As of December 31, 2023, there was $57.2 billion in outstanding indemnification guarantees.

Historically, we have had to pay approximately 0.1% of guarantees that we have issued and net chargeback expenses for the years ended December 31, 2023, 2022, and 2021, were $121.8 million, $103.2 million, and $85.5 million, respectively, which was in line with our budgets for the associated periods.

Non-Cancelable Purchase Obligations

In the normal course of business, we enter into non-cancelable purchase commitments with various parties primarily for hosting and software services. As of December 31, 2023, we had outstanding non-cancelable purchase obligations with a term of 12 months or longer as follows:

Other Indemnifications and Contingencies

In the ordinary course of business, we agree to indemnify certain parties. In our merchant agreements, we have agreed to indemnify, defend, and hold harmless the indemnified party for third-party claims and related losses suffered or incurred by the indemnified party from actual or threatened third-party intellectual property infringement claims. For certain large or strategic merchants, we have agreed to indemnify, defend and hold harmless the indemnified party for non-compliance with certain additional representations and warranties made by us. In addition, we have entered into indemnification agreements with our directors and certain officers. As we have a limited history of prior indemnification claims and the payments we have made under such agreements have not had a material adverse effect on our results of operations, cash flows, or financial position, we are unable to reasonably estimate the maximum potential amount of future payments related to these indemnification agreements. However, to the extent that valid indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our results of operations or cash flows in a particular period. As of December 31, 2023 and 2022, we did not have any material indemnification claims that were probable or reasonably possible.

Legal Proceedings

Occasionally we may be subject to various proceedings, lawsuits, disputes, or claims. We investigate these claims as they arise and accrue liabilities when losses are probable and reasonably estimated.

In May 2022, a putative securities class action complaint was filed in federal court in the United States by certain of our shareholders against us, certain of our current and former officers and directors, and our underwriters alleging violations of the Securities Act in connection with our IPO-related disclosures, and seeking unspecified damages. The lawsuit was captioned In re Riskified Ltd. Securities Litigation, 22 Civ. 3545 (DLC) (S.D.N.Y.). Plaintiffs filed an amended complaint on September 15, 2022. We moved to dismiss the amended complaint on October 28, 2022. On June 2, 2023, the Court granted our motion to dismiss the complaint in its entirety, with prejudice. The deadline to appeal has passed and the judgment is now final.

Although claims are inherently unpredictable, we are currently not aware of any matters that, if determined adversely to us, would individually or taken together, have a material adverse effect on our business, financial position, results of operations, or cash flows.

Leases

Our lease accounting policy under ASC Topic 840, “Leases” until January 1, 2022, prior to the adoption of the new lease guidance was as follows:

approximate the interest rate for collateralized borrowing with similar terms and payments and in economic environments where the leased asset was located.

We elected the practical expedient to not separate lease and non-lease components for our leases.

We sublease certain office spaces to third parties. Operating sublease income is recognized on a straight-line basis over the term of the agreement.

(1)Includes the warrants to purchase ordinary shares and warrants issued to customers.

Treasury Shares

In August 2023, the board of directors authorized the Company to repurchase up to $75.0 million of its Class A ordinary shares. We received approval for the implementation of our Repurchase Program from the Tel Aviv District Court Economic Department (“Israeli Court”) on November 20, 2023. The Israeli Court approval is valid through May 19, 2024. We may file extension requests with the Israeli Court on an ongoing basis as required. During the year ended December 31, 2023, we repurchased 3,038,865 outstanding Class A ordinary shares for $13.2 million, including transaction costs of approximately $0.1 million, through our Repurchase Program. These shares are classified as Treasury Shares on our consolidated balance sheet.

The Repurchase Program authorizes us to repurchase Class A ordinary shares, from time to time in the open market, in privately negotiated transactions or by other means in accordance with U.S. federal securities laws. The timing, as well as the number and value of any shares repurchased under the program, will be determined at our discretion under the Board authorized program and will depend on a variety of factors, including management's assessment of the intrinsic value of our ordinary shares, the market price of our ordinary shares, general market and economic conditions, available liquidity, alternative investment opportunities, and applicable legal requirements. The Repurchase Program does not obligate us to repurchase any specific number of shares and may be suspended, modified or discontinued at any time without prior notice. The share repurchases will be funded from existing cash and cash equivalents.

Equity Incentive Plan

The 2013 Equity Incentive Plan, or the 2013 Plan, was adopted by our board of directors on July 3, 2013 and amended and restated on February 23, 2021. The 2013 Plan provided for the grant of equity-based incentive awards to our employees, directors, office holders and consultants. The U.S. Sub-Plan to the 2013 Plan, which is to be read as a continuation of the 2013 Plan, was adopted by our board of directors on May 10, 2015 and amended and restated on February 23, 2021. The U.S. Sub-Plan governed equity-based incentive awards granted to our United States employees, directors, office holders and consultants, including those who are deemed to be residents of the United States for tax purposes.

We no longer grant any awards under our 2013 Plan as it was superseded by the 2021 Share Incentive Plan, or the 2021 Plan. Awards granted prior to the adoption of the 2021 Plan remain outstanding and are governed by the 2013 Plan.

The 2021 Plan was adopted in connection with our IPO on July 15, 2021. The 2021 Plan provides for the grant of equity-based incentive awards to our employees, directors, office holders, service providers and consultants. The maximum number of Class A ordinary shares available for issuance under the 2021 Plan is equal to the sum of (i) 13,951,037 Class A ordinary shares, (ii) any shares subject to awards under the 2013 Plan which have expired, or were cancelled, terminated, forfeited or settled in cash in lieu of issuance of shares or became unexercisable without having been fully exercised and (iii) an annual increase on the first day of each year beginning in 2022 and on January 1st of each calendar year thereafter during the term of the 2021 Plan, equal to the lesser of (A) 5% of the outstanding Class A ordinary shares of the Company on the last day of the immediately preceding calendar year (calculated on a fully diluted, as converted basis); and (B) such amount as determined by our board of directors if so determined prior to January 1 of a calendar year, provided that no more than 13,951,037 Class A ordinary shares may be issued upon the exercise of incentive share options.

Share Options and Shares Available for Grant

Share options generally vest over four years and expire ten years after the date of grant. We issue Class A ordinary shares upon exercise of share options. A summary of share options under our equity incentive plan and related information is as follows:


	Share Options Outstanding
	Outstanding Share Options	Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value
	(in thousands, except share, life and per share data)
Balance as of December 31, 2022	13,785,214	$	2.17	6.1	$	34,326
Options exercised	(3,010,478)	$	1.22
Options forfeited	(405,202)	$	3.72
Balance as of December 31, 2023	10,369,534	$	2.39	5.5	$	24,303
Exercisable as of December 31, 2023	8,849,876	$	2.13	5.2	$	22,904

There were no share options granted during the years ended December 31, 2023 or December 31, 2022. The weighted-average grant date fair value of share options granted during the year ended December 31, 2021 was $16.63. The aggregate grant date fair value of share options vested during the years ended December 31, 2023, 2022, and 2021 were $6.9 million, $12.0 million, and $3.2 million, respectively. The total intrinsic value of share options exercised during the years ended December 31, 2023, 2022, and 2021 were $11.3 million, $17.4 million, and $68.6 million, respectively. As of December 31, 2023, unrecognized share-based compensation cost related to unvested share options was $6.4 million, which is expected to be recognized over a weighted-average period of 1.3 years.

The Black-Scholes assumptions used to value the employee share options at the grant dates are as follows:


			Year Ended December 31,
			2021
Expected term (years)			5.44 - 6.60
Expected volatility			67.26% - 68.52%
Risk-free interest rate			0.99% - 1.12%
Expected dividend yield			0.00%

These assumptions and estimates were determined as follows:

•Fair Value of Ordinary Shares - Prior to IPO, the fair value was determined by our board of directors, with input from management and valuation reports prepared by third-party valuation specialists. Post IPO, the fair value of each ordinary share was based on the closing price of our publicly traded ordinary shares as reported on the date of the grant.

•Expected Term - The expected term represents the period that the share options are expected to be outstanding. For share option grants that are considered to be “plain vanilla,” we determine the expected term using the simplified method. The simplified method deems the term to be the average of the time-to-vesting and the contractual life of the share options.

•Expected Volatility - As we have a short trading history for our ordinary shares, the expected volatility is derived from the average historical share volatilities of several unrelated public

companies within our industry that we consider to be comparable to our own business over a period equivalent to the option’s expected term.

•Risk-Free Interest Rate - The risk-free rate for the expected term of the share options are based on the yields of U.S. Treasury securities with maturities appropriate for the expected term of employee share option awards.

•Expected Dividend Yield. - We have never declared or paid any cash dividends and do not presently plan to pay cash dividends in the foreseeable future. As a result, an expected dividend yield of zero percent was used.

Restricted Share Units

RSUs vest either upon the satisfaction of service-based vesting conditions, the satisfaction of both service-based and performance-based vesting conditions, or the satisfaction of service-based, performance-based, and market-based vesting conditions. Refer to Note 2 for more information regarding the vesting conditions of our RSUs. RSUs granted under the 2013 Plan can only vest prior to the expiration date of the award which is seven years from the date of grant. Any RSUs that have not vested will automatically terminate on their expiration date. RSUs granted under the 2021 Plan do not have an expiration date.

A summary of RSU activity, including activity under our equity incentive plan, and related information is as follows:


	Number of Shares	Weighted-Average Grant-Date Fair Value Per Share
Unvested as of December 31, 2022	19,412,262	$	9.06
Granted	10,904,664	$	5.43
Vested	(6,365,261)	$	7.28
Forfeited	(2,040,402)	$	6.31
Unvested as of December 31, 2023	21,911,263	$	8.02

As of December 31, 2023, total unrecognized share-based compensation expense related to unvested RSUs was approximately $115.0 million, which is expected to be recognized over a weighted-average period of 3.3 years.

2021 Employee Share Purchase Plan

We adopted the 2021 Employee Share Purchase Plan, or ESPP, in connection with our IPO on July 15, 2021, to enable eligible employees of the company and certain of its designated subsidiaries to use payroll deductions to purchase the company’s Class A ordinary shares and thereby acquire ownership interests in the Company. A total of 3,742,961 Class A ordinary shares are available for sale under the ESPP, subject to adjustment as provided for in the ESPP. In addition, on the first day of each fiscal year beginning on January 1, 2022 and ending on and including January 1, 2031, such pool of Class A ordinary shares shall be increased by that number of our Class A ordinary shares equal to the lesser of: (i) 1% of the outstanding Class A ordinary shares as of the last day of the immediately preceding fiscal year (calculated on a fully diluted as-converted basis); or (ii) such smaller amount as our board of directors may determine. In accordance with the above, our board of directors determined not to increase the number of Class A ordinary shares available for sale under the ESPP as of January 1, 2022, January 1, 2023, or January 1, 2024.

Generally, all of our employees are eligible to participate if they are employed by us. However, an employee may not be granted rights to purchase our ordinary shares under the ESPP if such employee (i)

immediately after the grant would own capital shares or hold outstanding share options to purchase such shares possessing 5% or more of the total combined voting power or value of all classes of our shares or any of our subsidiaries.

As of December 31, 2023, we have not effected any offering under the ESPP.

CEO Multi-Year Equity Award

In July 2021, our board of directors and shareholders granted to our chief executive officer, Mr. Gal, a multi-year equity award, comprising 3,993,440 RSUs (the “Multi-Year Award”). The grant date fair value of the Multi-Year Award, which is the amount of share-based compensation expense that we recognize, is primarily determined based on the share price on the date the award was granted and is not based on our current share price. This amount is expensed utilizing the accelerated attribution method over the requisite service period of ten years. This method attributes higher expenses to the earlier periods of the requisite service period.

The Multi-Year Award is structured so that meaningful value may only be realized upon the achievement of sustained and significant high performance levels. The award is divided into ten tranches that are eligible to vest based on the achievement of stock price goals, which range from $26.67 to $106.67, measured based on the average of our stock price over a trailing 60 trading day period during predefined performance periods, subject to Mr. Gal’s continued employment as our chief executive officer through each such period. In order to earn all of the tranches, the stock price will have to be more than 5 times higher than the price at IPO. No tranches of the Multi-Year Award were earned or vested in 2023.

In addition to the service-based vesting condition, and market-based vesting condition, each described above, the Multi-Year Award is also subject to a performance-based vesting condition. The performance-based vesting condition underlying the Multi-Year Award was satisfied upon the occurrence of our IPO in 2021. We recognized $8.6 million, $13.0 million, and $6.0 million in share-based compensation expense related to the Multi-Year Award during the years ended December 31, 2023, 2022, and 2021, respectively.

As of December 31, 2023 and 2022, we did not have any Level 3 financial instruments that are measured at fair value on a recurring basis.

We classify our derivative financial instruments and government bonds within Level 2 of the fair value hierarchy because they are valued using inputs other than quoted prices which are directly or indirectly observable in the market, including readily-available pricing sources for the identical underlying security which may not be actively traded. Refer to Note 5 for more information regarding our derivative financial instruments.

Refer to Note 8 below for more information regarding the fair value of our indemnification guarantees.

*Revenue recognized from merchants whose headquarters are in Israel, which is our country of domicile, was $1.3 million, $3.3 million, and $2.4 million for the years ended December 31, 2023, 2022, and 2021, respectively.

The following table summarizes revenue based on the nature and type of service provided to our merchants:


	Year Ended December 31,
	2023				2022				2021
	Amount		Percentage of Revenue		Amount		Percentage of Revenue		Amount		Percentage of Revenue

Fraud review service revenue (ASC 606)	$	167,278	56	%	$	156,040	60	%	$	132,261	58	%
Indemnification guarantee service revenue (ASC 460)	130,332		44		105,207		40		96,880		42
Total revenue	$	297,610	100	%	$	261,247	100	%	$	229,141	100	%

We primarily generate revenue from our Chargeback Guarantee offering. Revenue generated from other offerings are not material.

The allocation of consideration between fraud review service revenue and indemnification guarantee service revenue is a function of the fair value of our chargeback guarantee which represents what we would need to pay a third party to relieve ourselves from our obligations under issued guarantees. The fair value of the chargeback guarantee is primarily determined by utilizing the historical percentage of guarantees issued that resulted in a chargeback plus a risk premium fee that we would have incurred from a third-party in order to relieve ourselves from our legal obligation under the guarantee. Refer to Item 5. “Operating and Financial Review and Prospects — Critical Accounting Policies and Estimates.”

Changes in the percentage of revenue that are recorded as fraud review service revenue and indemnification guarantee service revenue are a function of changes in the aforementioned fair value of the chargeback guarantee and changes in the speed in which we resolve chargeback claims which impacts the systematic and rational approach that we utilize to record revenue associated with our guarantee obligation.

Income Tax Disclosure [Abstract]

Income Taxes

11. Income Taxes

Ordinary taxable income in Israel is subject to a corporate tax rate of 23%. However, the effective tax rate payable by a company that derives income from a Preferred Technological Enterprise (as discussed below) may be considerably less. Capital gains (which are not ‘Inflationary Surplus’, as described below) derived by an Israeli company are generally subject to the prevailing corporate tax rate.

Law for the Encouragement of Capital Investments, 1959

The Law for the Encouragement of Capital Investments, 1959, generally referred to as the Investment Law, provides certain incentives for capital investments in production facilities (or other eligible assets).

The Investment Law was significantly amended effective on April 1, 2005, January 1, 2011, and on January 1, 2017, or the 2017 Amendment. The 2017 Amendment introduces new benefits for Technological Enterprises, alongside the existing tax benefits.

The 2017 Amendment was enacted as part of the Economic Efficiency Law that was published on December 29, 2016, and is effective as of January 1, 2017. The 2017 Amendment included new tax benefits for “Technological Enterprises,” as described below, and is in addition to the other existing tax beneficial programs under the Investment Law.

The 2017 Amendment provides that a technology company satisfying certain conditions should qualify as a “Preferred Technology Enterprises,” or PTE, granting a 12% tax rate in central Israel on income deriving from Benefited Intangible Assets, subject to a number of conditions being fulfilled, including a minimal amount or ratio of annual R&D expenditure and R&D employees, as well as having at least 25% of annual income derived from exports to large markets. PTE is defined as an enterprise which meets the aforementioned conditions and for which total consolidated revenues of its parent company and all subsidiaries are less than NIS 10 billion.

The Company has not adopted the PTE status currently, but believe we are eligible for the PTE status in future tax years and have tax-effected our Israel deferred tax assets and liabilities at the appropriate PTE rates. Our subsidiaries are separately taxed under the domestic tax laws of the jurisdiction of incorporation of each entity.

Profit (loss) before the provision for income taxes consisted of the following for the years ended December 31, 2023, 2022, and 2021:

Change in valuation allowance	2,961		12,123		4,444
Total	$	5,798	$	6,042	$	1,558

Our effective tax rate was (10.89)% for the year ended December 31, 2023, compared to an effective tax rate of (6.12)% for the year ended December 31, 2022 and (0.88)% for the year ended December 31, 2021. The effective tax rates for the periods presented are primarily comprised of Israel statutory taxes, warrant revaluation, share-based compensation expense, uncertain tax positions, and changes in valuation allowance position. The difference in the effective tax rate of (10.89)% for the year ended December 31, 2023 as compared to the effective tax rate of (6.12)% for the year ended December 31, 2022 and (0.88)% for the year ended December 31, 2021 was related to non-deductible share-based compensation, prior period adjustments, uncertain tax positions, and change in valuation allowance position in Israel and in our U.S. subsidiary.

The provision for income taxes was $5.8 million, $6.0 million and $1.6 million for the years ended December 31, 2023, 2022, and 2021, respectively. The provision for income taxes for the year ended December 31, 2023 consisted primarily of income taxes related to the United States and other foreign jurisdictions in which we conduct business.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

The following table presents the significant components of our deferred tax assets and liabilities:


	Year Ended December 31,
	2023		2022		2021

Gross deferred tax liabilities	(9,198)		(10,266)		(3,004)
Net deferred tax assets/(liabilities)	$	5	$	(11)	$	(2,688)

As of December 31, 2023 and 2022, we had Israel net operating loss, or NOL, carryforwards of approximately $75.7 million and $68.9 million, respectively, which do not expire. As of December 31, 2023 and 2022, we had U.S. Federal NOL carryforwards of approximately $11.7 million and $11.2 million respectively, which do not expire. As of December 31, 2023, we had U.S. State NOL carryforwards of approximately $24.8 million, of which $23.3 million expire between 2028 and 2043, and the remaining $1.5 million do not expire. As of December 31, 2022, we had U.S. State NOL carryforwards of approximately $16.6 million, of which $15.4 million expire between 2027 and 2042, and the remaining $1.2 million do not expire.

During the years ended December 31, 2023, 2022, and 2021 the net change in the valuation allowance against deferred tax assets amounted to an increase of $3.0 million, an increase of $12.1 million, and an increase of $4.4 million, respectively. The increase in the valuation allowance during the years ended December 31, 2023, December 31, 2022 and December 31, 2021 was largely attributable to the generation of Israel NOLs, and certain US state NOLs.

In establishing deferred income tax assets and liabilities, management makes judgments based on the enacted tax laws and published tax guidance applicable to us as well as the amount and jurisdiction of future taxable income. Deferred tax assets and liabilities are recorded and the need for valuation allowances is evaluated to reduce the deferred tax assets to amounts expected to be realized. As of December 31, 2023 and 2022, we maintained a full valuation allowance on Israel and U.S. net deferred tax assets as we believe, after weighing both the positive and negative evidence, that it is more likely than not that these deferred tax assets will not be realized.

The Internal Revenue Code of 1986, as amended, imposes restrictions on the utilization of NOLs in the event of an “ownership change” of a corporation. Accordingly, a company’s ability to use NOLs may be limited as prescribed under Internal Revenue Code Section 382, or IRC Section 382. Events which may cause limitations in the amount of the NOLs that we may use in any one year include, but are not limited to, a cumulative ownership change of more than 50% over a three-year period. Utilization of the U.S. federal and state NOLs may be subject to substantial annual limitation due to the ownership change limitations provided by the IRC Section 382 and similar state provisions. We have completed our evaluation of NOL utilization limitations under Internal Revenue Code, as amended, or the Code, Section 382, change of ownership rules, and have found that the NOLs would not be limited as to the amount that could be used in the current tax year.

We have identified unrecognized tax benefits or uncertain tax positions. There has been a liability on uncertain tax positions recorded on our audited consolidated financial statements as of December 31, 2023 and 2022. We do not expect that our assessment regarding unrecognized tax benefits and uncertain tax positions will materially change over the following 12 months.

A reconciliation of the beginning and ending balance of total unrecognized tax position is as follows:


	Unrecognized Tax Benefits
	(in thousands)
Balance – January 1, 2021	234
Additions based on tax positions related to current year	3,885
Reductions for tax positions of prior years	—
Balance – December 31, 2021	4,119
Additions based on tax positions related to current year	7,187
Reductions for tax positions of prior years	(54)
Balance – December 31, 2022	$	11,252
Additions based on tax positions related to current year	5,273
Reductions for tax positions of prior years	(13)
Balance – December 31, 2023	$	16,512

As of December 31, 2023 and 2022, the total amount of gross unrecognized tax benefits was $16.5 million and $11.3 million, respectively, which, if recognized, would affect our effective tax rate. We have elected to include interest and penalties as a component of tax expense. As of December 31, 2023 and 2022, we have accumulated $1.0 million and $320 thousand, respectively, in both interest and penalties associated with uncertain tax positions. We do not expect unrecognized tax benefits to change significantly within the next twelve months.

We are not currently under audit for income taxes. As of December 31, 2023, tax years beginning with the year ended December 31, 2019 remain subject to examination by the Israel tax authorities and tax years beginning with the year ended December 31, 2020 remain subject to examination by the Internal Revenue Service and certain U.S. state jurisdictions.
