REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of The Trade Desk, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of The Trade Desk, Inc. and its subsidiaries (the “Company”) as of December 31, 2022 and 2021, and the related consolidated statements of operations, of stockholders' equity and of cash flows for each of the three years in the period ended December 31, 2022, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition – Platform Fees

As described in Note 2 to the consolidated financial statements, the Company maintains agreements with each client and supplier in the form of master service agreements, which set out the terms of the relationship and access to the Company’s platform. The Company’s performance obligation is to provide the use of its platform to clients to develop ad campaigns and select the advertising inventory, data and other add-on features. The Company charges clients a platform fee, based on a percentage of a client’s purchases through the platform. The Company recognizes revenue for its platform fee at a point in time when the purchase by a client occurs through its platform. Management reports revenue on a net basis for the platform fees charged to clients. For the year ended December 31, 2022, the Company’s revenue was $1,578 million.

The principal consideration for our determination that performing procedures relating to revenue recognition – platform fees is a critical audit matter is the high degree of audit effort in performing procedures related to client purchases through the Company’s platform to recognize revenue.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the completeness and accuracy of the revenue recognized for platform fees charged to clients, including both manual and automated controls operating over the information generated from the Company’s platform and the calculation of revenue invoices based on client purchases. These procedures also included, among others (i) evaluating revenue transactions by testing the issuance and settlement of invoices and credit memos; (ii) tracing transactions not settled to a detailed listing of accounts receivable; (iii) confirming a sample of outstanding client invoice balances at year end and, for confirmations not returned, obtaining and inspecting source documents, including invoices, master service agreements, subsequent cash receipts, and recalculating platform fees due, where applicable; and (iv) testing the completeness and accuracy of underlying information provided by management.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Nature of Operations

The Trade Desk, Inc. (the “Company”) is a global technology company that empowers buyers of advertising. Through the Company’s self-service, cloud-based platform, ad buyers can create, manage and optimize more expressive data-driven digital advertising campaigns across ad formats and channels, including video (which includes connected TV (“CTV”)), display, audio, digital-out-of-home, native and social, on a multitude of devices, such as computers, mobile devices, televisions and streaming devices. The Company’s platform integrations with major inventory, publisher and data partners provide ad buyers reach and decisioning capabilities, and the Company’s enterprise application programming interfaces (“APIs”) enable its clients to develop on top of the platform.

The Company is a Delaware corporation formed in November 2009 and headquartered in Ventura, California with offices in various cities in North America, Europe, Asia and Australia.

Note 2—Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the operations of the Company and its wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation.

On June 16, 2021, the Company effected a ten-for-one stock split (the “Stock Split”) of the Company’s common stock in the form of a stock dividend. Each stockholder of record on June 9, 2021 received nine additional shares of common stock for each then-held share. Trading began on a stock split-adjusted basis on June 17, 2021. The number of shares subject to outstanding equity awards and the exercise prices of the outstanding stock option awards were also adjusted to reflect the effect of the Stock Split. All share and per share amounts presented herein have been retroactively adjusted to reflect the impact of the Stock Split.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from these estimates.

Management regularly evaluates its estimates, primarily those related to: (1) revenue recognition criteria, including the determination of revenue reporting as net versus gross in the Company’s revenue arrangements, (2) allowances for credit losses, (3) operating lease assets and liabilities, including the incremental borrowing rate and terms and provisions of each lease (4) the useful lives of property and equipment and capitalized software development costs, (5) income taxes, (6) assumptions used in the option pricing models to determine the fair value of stock-based compensation and (7) the recognition and disclosure of contingent liabilities. These estimates are based on historical data and experience, as well as various other factors that management believes to be reasonable under the circumstances; the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources.

As of December 31, 2022, the impacts to the Company’s business due to the coronavirus (“COVID-19”) pandemic, geopolitical developments and macroeconomic factors, such as rising interest rates, inflation, changes in foreign currency exchange rates and supply chain disruptions, continue to evolve. As a result, many of the Company’s estimates and assumptions, including the allowance for credit losses, consider macroeconomic factors in the market, which require increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, the Company’s estimates may change materially in future periods.

Revenue Recognition

The Company generates revenue from clients who enter into agreements with the Company to use its platform to purchase advertising inventory, data and other add-on features. The Company charges its clients a platform fee, which is a

Table of Contents

percentage of a client’s purchases through the platform. In addition, the Company invoices its clients for the cost of advertising inventory purchased, plus data and any add-on features purchased through the platform.

The Company determines revenue recognition through the following steps:

• Identification of a contract with a client;

• Identification of the performance obligations in the contract;

• Determination of the transaction price;

• Allocation of the transaction price to the performance obligations in the contract; and

• Recognition of revenue when or as the performance obligations are satisfied.

The Company maintains agreements with each client and supplier in the form of master service agreements (“MSAs”), which set out the terms of the relationship and access to the Company’s platform. The Company’s performance obligation is to provide the use of its platform to clients to develop ad campaigns and select the advertising inventory, data and other add-on features. The Company charges clients a platform fee, based on a percentage of a client’s purchases through the platform. The transaction price is determined based on the consideration the Company expects to be entitled in exchange for the completion of a transaction, that is, when a bid is won. The platform fee percentage is based on the level of purchases by the client through the platform during the month. The Company recognizes revenue for its platform fee at a point in time when a purchase by the client occurs through its platform, which is when a bid is won. The associated fees are generally not subject to refund or adjustment after a bid is won. Historically, any refunds and adjustments have not been material.

Generally, the Company reports revenue net of amounts it pays suppliers for the cost of advertising inventory, third-party data and other add-on features (collectively, “Supplier Features”). Judgment is required to determine whether the Company is the principal and reports revenue on a gross basis for Supplier Features or the agent and reports revenue on a net basis for the amount of platform fees charged to the client. The Company determined that it is not primarily responsible for the purchase of Supplier Features. Rather, the Company’s primary responsibility is to provide the platform that enables clients to bid on advertising inventory and use data and other add-on features in designing and executing their campaigns. The Company does not control the Supplier Features prior to the purchase by the client, and it does not have pricing latitude with respect to the cost of such features. The platform fee the Company charges clients is a percentage of their purchases through its platform, similar to a commission, and the platform fee is not contingent on the results of an advertising campaign. Based on these and other factors, the Company determined that it is not the principal in the purchase and sale of Supplier Features and, therefore, reports revenue on a net basis for the platform fees charged to clients.

From time to time, the Company may enter into agreements with data suppliers where the purchased data is used to inform and improve the platform, generally at no additional charge to customers outside of the standard fees. Costs associated with this data (“data-related costs”) are recorded in platform operations expense.

The Company generally bills clients for the gross amount of Supplier Features they purchase through its platform and the platform fees (“Gross Billings”), net of allowances. When clients have direct payment relationships with advertising inventory suppliers, the Company bills these clients only for third-party data, other add-on features and its platform fees. The Company invoices its clients monthly for the purchases occurring during the month. Typically, invoice payment terms are between 30 to 90 days. However, certain agency clients have sequential liability terms where payment is not due to the Company until the agency has received payment from its advertiser clients. Accounts receivable is recorded based on Gross Billings, which are the amounts the Company is responsible to collect. Accounts payable is recorded at the net amount payable to suppliers. Accordingly, both accounts receivable and accounts payable appear large in relation to revenue reported on a net basis.

Refer to Note 12—Segment and Geographic Information for geographic information related to Gross Billings.

Operating Expenses

The Company classifies its operating expenses into four categories and allocates overhead such as information technology infrastructure, rent and occupancy charges based on headcount for all these categories:

Platform Operations. Platform operations expense consists of expenses related to hosting the Company’s platform, which includes “internet traffic” associated with the viewing of available impressions or queries per second

Table of Contents

(“QPS”), purchasing data used to inform and improve the platform and providing support to clients. Platform operations expense includes hosting costs, data-related costs, personnel costs and amortization of acquired technology and capitalized software costs for platform development. Personnel costs include salaries, bonuses, stock-based compensation and employee benefit costs attributable to personnel who support the platform and provide clients with platform support. The Company capitalizes certain costs associated with platform development in other assets, non-current on its consolidated balance sheet and amortizes these costs into platform operations expense over their estimated useful lives.

Sales and Marketing. Sales and marketing expense consists primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs and commission costs, for the Company’s sales and marketing personnel. Sales and marketing expense also includes costs for market development programs, advertising and promotional and other marketing activities. Commissions costs are expensed as incurred.

Technology and Development. The Company’s technology and development expense consists primarily of personnel costs, including salaries, bonuses, stock-based compensation and employee benefits costs; third-party consultant costs associated with the ongoing development of the Company’s platform and integrations with advertising and data inventory suppliers; and the amortization of capitalized third-party software used in platform development. Technology and development costs are expensed as incurred, except to the extent that such costs are associated with software development that qualifies for capitalization, which are then recorded as capitalized software development costs included in other assets, non-current on the Company’s consolidated balance sheet. The Company amortizes capitalized software development costs relating to the Company’s platform to platform operations expense.

General and Administrative. The Company’s general and administrative expense consists primarily of personnel costs, including salaries, bonuses, stock-based compensation and employee benefits costs associated with the Company’s executive, finance, legal, human resources, compliance and other administrative personnel, as well as accounting and legal professional services fees and credit loss expense. Stock-based compensation in general and administrative expenses also includes expense related to the CEO Performance Option, which was granted in 2021.

Stock-Based Compensation

Stock-based compensation expense related to stock options, restricted stock awards and units (collectively, “restricted stock”) and awards granted under the Company’s employee stock purchase plan (“ESPP”) is measured and recognized in the consolidated financial statements based on the fair value of the awards granted.

The fair values of the ESPP and stock option awards are estimated on the grant date using the Black-Scholes option-pricing model, except for the CEO Performance Option, granted in 2021, that was estimated using the Monte Carlo valuation model. The fair value of restricted stock is calculated using the closing market price of the Company’s common stock on the date of grant. Determining the fair value of stock options and ESPP awards requires judgment. The Company’s use of the valuation models requires the input of subjective assumptions. The assumptions used in the Company’s valuation models represent management’s best estimates, which involve inherent uncertainties and the application of management’s judgment. The Company will continue to use judgment in evaluating the assumptions related to its stock-based compensation.

These assumptions and estimates are as follows:

Risk-Free Interest Rate. The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities approximating the expected term of the awards.

Expected Term. For stock options, given the insufficient historical data relating to stock option exercises, the Company applies the simplified approach in which the expected term of an award is presumed to be the mid-point between the vesting date and the expiration date of the award. For ESPP awards, the expected term is the time period from the grant date to the respective purchase dates included within each offering period.

Volatility. Prior to 2020, the Company determined the price volatility based on a blend of the historical volatilities of a publicly traded peer group, implied volatilities from its traded options, and its historical volatility, based on daily price observations over a period equivalent to the expected term of the award. During 2020, the Company eliminated the peer group from this analysis and began to determine its price volatility based on a blend of historical and implied volatilities.

Table of Contents

Dividend Yield. The dividend yield assumption is based on the Company’s history and current expectations of dividend payouts. The Company has never declared or paid any cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future, so the Company used an expected dividend yield of zero.

Derived Service Period. The stock-compensation expense attribution period for the CEO Performance Option, which was granted in 2021, was developed based on a Monte Carlo simulation of daily stock prices over the performance period.

Stock-based compensation expense related to stock options and restricted stock is recognized on a straight-line basis over the requisite service periods of the awards, which is generally four years. Stock-based compensation for the CEO Performance Option is recognized on a graded-vesting basis over a derived service period of approximately five years but may be accelerated if the vesting criteria are met prior to the estimated performance period. Stock-based compensation expense for ESPP awards is recognized on a graded-vesting attribution basis over the requisite service period of each award. The Company accounts for forfeitures as they occur.

Income Taxes

Deferred income tax assets and liabilities are determined based upon the net tax effects of the differences between the Company’s consolidated financial statements carrying amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed. A valuation allowance is used to reduce some or all of the deferred tax assets if, based upon the weight of available evidence, it is more likely than not that those deferred tax assets will not be realized.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized. The Company recognizes interest and penalties accrued related to its uncertain tax positions in its income tax provision in the accompanying consolidated statements of operations.

The Company makes assumptions, judgments and estimates to determine the current income tax provision, tax benefits from uncertain tax positions, deferred tax asset and liabilities and valuation allowance recorded against a deferred tax asset.

The assumptions, judgments and estimates relative to the current income tax provision (benefit) take into account current tax laws, their interpretation and possible results of foreign and domestic tax audits. Changes in tax law, and their interpretation, could significantly impact the income taxes provided in the Company’s consolidated financial statements.

The evaluation of the Company’s uncertain tax positions involves significant judgment in the interpretation and application of GAAP and complex domestic and international tax laws, and matters related to the allocation of international taxation rights between countries. Although management believes the Company’s reserves are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in the Company’s reserves. Reserves are adjusted considering changing facts and circumstances, such as the closing of a tax examination or the refinement of an estimate.

Assumptions, judgments and estimates relative to the amount of deferred income taxes, and any applicable valuation allowances, take into account future taxable income. Any of the assumptions, judgments and estimates mentioned above could cause the actual income tax obligations to differ from estimates.

Earnings Per Share

Basic earnings per share is calculated by dividing net income by the weighted-average number of common stock shares outstanding. Diluted earnings per share is calculated by dividing net income by the weighted-average number of common stock shares outstanding adjusted for the potentially dilutive impact of stock options, restricted stock and ESPP using the using the two-class method required for participating securities. Restricted stock awards are considered to be participating securities due to their non-forfeitable dividend rights.

Table of Contents

Cash, Cash Equivalents and Marketable Securities

The Company classifies all investments that are readily convertible to known amounts of cash and have maturities of three months or less from the date of purchase as cash equivalents, which consist primarily of money market funds and commercial paper and those with stated maturities of greater than three months as marketable securities, which primarily consist of corporate debt securities and U.S. government and agency securities. Investments in marketable securities with maturities beyond one year are also classified as short-term available-for-sale securities based on their highly liquid nature and because they are available for current operations.

Cash equivalents and marketable securities are carried at fair value. Realized gains and losses are recognized in other expense (income), net on the consolidated statement of operations. Unrealized gains and losses, net of taxes, are included in stockholders' equity. The Company uses Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (Accounting Standards Codification (“ASC”) 326 or “CECL”), to assess the investment portfolio for impairment at the individual security level and evaluates all securities in an unrealized loss position to determine if the impairment is credit related (resulting in realized credit loss, recorded in earnings) or non-credit related (resulting in an unrealized loss, recorded in stockholders' equity). The Company has not recorded any impairment charges for unrealized losses in the periods presented. Credit losses recorded in the statements of operations for the years ended 2022, 2021 and 2020 were not material.

Refer to Note 6—Cash, Cash Equivalents and Short-Term Investments, Net for additional information regarding the fair value of cash equivalents and marketable securities.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are recorded at the invoiced amount, are unsecured and do not bear interest. The Company performs ongoing credit evaluations of its clients and certain advertisers when the Company’s agreements with its clients contain sequential liability terms such that client payments are not due to the Company until the client has received payment from its clients who are advertisers. The Company maintains an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense on the consolidated statements of operations.

On January 1, 2020, the Company adopted ASC 326 to assess the allowance for credit losses. The Company used the modified retrospective transition method, which required a cumulative-effect adjustment to the opening balance of retained earnings to be recognized on the date of adoption with prior periods not restated. The cumulative-effect adjustment recorded on January 1, 2020 was not material. ASC 326 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. As a result, the Company revised its impairment model to utilize an expected loss methodology in place of an incurred loss methodology related to its marketable securities and the related allowance for credit losses. Industry-specific default rates are applied to the advertiser’s industry if the receivables are subject to sequential liability or the Company is engaged with the advertiser directly.

For the years ended December 31, 2022 and 2021, the Company’s assessment considered business and market disruptions caused by macroeconomic factors, such as changes in interest rates, inflation, economic growth and the COVID-19 pandemic, and estimates of credit defaults by industry. The Company continues to monitor the financial implications of these macroeconomic factors on expected credit losses by reviewing the allowance for credit losses on a quarterly basis. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.

The following table presents changes in the accounts receivable allowance for credit losses (in thousands):

			Year Ended December 31,

Property and Equipment, Net

Property and equipment are recorded at historical cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method based upon the following estimated useful lives:

			Years
Computer equipment			2 – 3
Purchased software			3 – 5
Furniture, fixtures and office equipment			5
Leasehold improvements			*

____________

*Leasehold improvements are amortized on a straight-line basis over the term of the lease, or the useful life of the assets, whichever is shorter.

Repair and maintenance costs are charged to expense as incurred, while improvements are capitalized. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the Company’s operating results.

Capitalized Software Development Costs

The Company capitalizes certain costs associated with creating and enhancing internally developed software related to the Company’s technology infrastructure. These costs include personnel and benefit-related expenses for employees who are directly associated with and devote time to software development projects, and external direct costs of materials and services consumed in developing or obtaining the software. Software development costs that do not qualify for capitalization, as further discussed below, are expensed as incurred and recorded in technology and development expenses in the consolidated statements of operations.

Software development activities typically consist of three stages: (1) the planning phase; (2) the application and infrastructure development stage; and (3) the post-implementation stage. Costs incurred in the planning and post implementation phases, including costs associated with the post-configuration training and repairs and maintenance of the developed technologies, are expensed as incurred. The Company capitalizes costs associated with software developed when the preliminary project stage is completed, management implicitly or explicitly authorizes and commits to funding the project and it is probable that the project will be completed and perform as intended. Costs incurred in the application and infrastructure development phases, including significant enhancements and upgrades, are capitalized. Capitalization ends once a project is substantially complete and the software is ready for its intended purpose. Software development costs are amortized using a straight-line method over the estimated useful life of two years, commencing when the software is ready for its intended use. The straight-line recognition method approximates the manner in which the expected benefit will be derived.

The Company does not transfer ownership of its internally developed software, or lease its software, to third parties.

Cloud computing arrangements (“CCAs”), such as software as a service and other hosting arrangements, are evaluated for capitalized implementation costs in a similar manner as capitalized software development costs. If a CCA includes a software license, the software license element of the arrangement is accounted for in a manner consistent with the acquisition of other software licenses. If a CCA does not include a software license, the service element of the arrangement is accounted for as a service contract. The Company capitalized certain implementation costs for its CCAs that are service contracts, which are included in other assets, non-current. The Company amortizes capitalized implementation costs in a CCA over the life of the service contract. The Company capitalized $2 million of CCA implementation costs in both 2022 and 2021. Amortization expense was $2 million, $1 million and $1 million for 2022, 2021 and 2020, respectively.

Operating Leases

The Company enters into operating leases for its offices, which have lease terms of up to 10 years, some of which include options to extend the leases for up to five years, and some of which include options to terminate the leases within one year with proper notification. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company does not have finance leases.

Table of Contents

The Company determines if an arrangement is, or contains, a lease at inception. Operating lease assets represent the Company’s right to control the use of an identified asset for a period of time, or term, in exchange for consideration, and operating lease liabilities represent its obligation to make lease payments arising from the aforementioned right.

Operating lease assets and liabilities are initially recorded based on the present value of lease payments over the lease term, which includes the minimum unconditional term of the lease, and may include options to extend or terminate the lease when it is reasonably certain at the commencement date that such options will be exercised. As the rate implicit for each of the Company’s leases is not readily determinable, the Company uses its incremental borrowing rate, based on the information available at the lease commencement date in determining the present value of its expected lease payments. Operating lease assets also include any initial direct costs and any lease payments made prior to the lease commencement date and are reduced by any lease incentives received. The Company has elected to not separate lease and non-lease components.

Operating lease assets are amortized on a straight-line basis in operating lease expense over the lease term on the consolidated statements of operations. The related amortization, referred to as noncash lease expense, along with the change in the operating lease liabilities are separately presented within the cash flows from operating activities on the consolidated statements of cash flows. The Company records lease expense for operating leases, some of which have escalating rent payments, on a straight-line basis over the lease term.

Certain leases contain provisions for property-related costs that are variable in nature for which the Company is responsible, including common area maintenance and other property operating services. These costs are calculated based on a variety of factors including property values, tax and utility rates, property services fees and other factors.

Refer to Note 8—Leases for additional information.

Fair Value of Financial Instruments

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value measurements are based on a fair value hierarchy, based on three levels of inputs, of which the first two are considered observable and the last unobservable, which are the following:

Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted market prices for similar assets and 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 asset or liability.

Level 3—Unobservable inputs.

Observable inputs are based on market data obtained from independent sources.

The carrying amounts of accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities approximate fair value due to the short-term nature of these instruments. The carrying value of the line of credit approximates fair value based on borrowing rates currently available to the Company for financing with similar terms and were determined to be Level 2.

Certain long-lived assets including capitalized software development costs are also subject to measurement at fair value on a non-recurring basis if they are deemed to be impaired as a result of an impairment review. To date, no material impairments have been recorded on those assets.

Concentration of Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents, short-term investments and accounts receivable. The Company maintains its cash and cash equivalents with financial institutions, and its cash levels exceed the Federal Deposit Insurance Corporation federally

Table of Contents

insured limits. Short-term investments consist of investments in U.S. government securities, U.S. government agency securities, and high-credit quality corporate debt securities.

If all of the Company’s individual client contractual relationships were aggregated at the holding company level, one holding company would represent more than 10% of Gross Billings in 2022, and two holding companies would each represent more than 10% of Gross Billings in 2021 and 2020. In 2022, one holding company accounted for 11% of Gross Billings. In 2021, two holding companies accounted for 11% and 10% of Gross Billings, respectively. In 2020, two holding companies each accounted for 11% of Gross Billings. The Company generally does not have contractual relationships with holding companies. Rather, in most cases, the Company enters into separate contracts and billing relationships with various of their individual agencies and account for those agencies as separate clients.

As of December 31, 2022, four clients each accounted for at least 10%, and collectively accounted for 49%, of consolidated accounts receivable. As of December 31, 2021, three clients each accounted for at least 10%, and collectively accounted for 41%, of consolidated accounts receivable.

As of December 31, 2022, two suppliers each accounted for at least 10%, and collectively accounted for 25%, of consolidated accounts payable. As of December 31, 2021, one supplier accounted for 17% of consolidated accounts payable.

Foreign Currency Transactions

The Company’s reporting currency is the U.S. Dollar, and the functional currency of each of the Company’s subsidiaries is the U.S. Dollar. Transactions in foreign currencies are translated into U.S. Dollars at the rates of exchange in effect at the date of the transaction. Net transaction gains are included in foreign currency exchange loss (gain), net in the accompanying consolidated statements of operations.

The Company enters into forward contracts to hedge foreign currency exposures related primarily to the Company’s foreign currency denominated accounts receivable. The Company does not designate the foreign exchange forward contracts as hedges for accounting purposes and changes in the fair value of the foreign exchange forward contracts are recorded in foreign currency exchange loss (gain), net in the accompanying consolidated statements of operations. The Company’s forward contracts generally have terms of 30-60 days. As of December 31, 2022, and 2021, the Company had open forward contracts with aggregate notional amounts of $142 million and $126 million, respectively. The 2021 aggregate notional amount has been updated to exclude contracts closed but unsettled at December 31, 2021. The fair value of the open forward contracts was not material.

Business Combinations

The results of a business combination are included in the Company’s consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business are generally recorded at their estimated fair values on the acquisition date, which may require management to use significant judgment and estimates, including the selection of valuation methodologies, estimates of future revenue, costs and cash flows, discount rates and selection of comparable companies. The Company engages valuation specialists to assist in determining the fair values of these acquired assets and liabilities. Any excess consideration over the fair value of these acquired assets and liabilities assumed is recognized as goodwill.

In July 2021, the Company acquired all of the equity interests of a technology company for a GAAP purchase price of $18 million, subject to purchase price adjustments. The purchase consideration was primarily attributable to non-deductible goodwill of $11 million, with the remainder allocated to acquired technology and other assets. No other acquisitions occurred in 2022 or 2021.

Note 3—Earnings Per Share

The Company has two classes of common stock, Class A and Class B. Basic and diluted earnings per share (“EPS”) attributable to common stockholders for Class A and Class B common stock were the same because they were entitled to the same liquidation and dividend rights.

Note 7—Debt

Credit Facility

On June 15, 2021, the Company and a syndicate of banks, led by JPMorgan Chase Bank, N.A., as agent, entered into a Loan and Security Agreement (the “Credit Facility”). The Credit Facility replaced the Company’s prior credit facility, which was scheduled to terminate in May 2022. The Credit Facility consists of a $450 million revolving loan facility, with a $20 million sublimit for swingline borrowings and a $15 million sublimit for the issuance of letters of credit. Under certain circumstances, the Company has the right to increase the Credit Facility by an amount not to exceed $300 million. The Credit Facility is collateralized by substantially all of the Company’s assets, including a pledge of certain of its accounts receivable, deposit accounts, intellectual property, investment property, and equipment.

As of December 31, 2022, loans under the Credit Facility bore interest through maturity at a variable rate based upon, at the Company’s option, an annual rate of either a Base Rate or an adjusted London Interbank Offered Rate

Table of Contents

(“LIBOR”), plus an applicable margin (“Base Rate Borrowings” and “LIBOR Rate Borrowings”). The Base Rate was defined as a rate per annum for any day equal to the greatest of (1) the rate of interest last quoted by The Wall Street Journal as the “Prime Rate” in the United States, (2) the New York Federal Reserve Bank (“NYFRB”) Rate in effect on such day plus half of 1% and (3) the adjusted LIBOR rate for a one-month interest period on such day plus 1%. The applicable margin was between 0.25% to 1.25% for Base Rate Borrowings and between 1.25% and 2.25% for LIBOR Rate Borrowings based on the Company maintaining certain leverage ratios. The fee for undrawn amounts under the Credit Facility ranges, based on the applicable leverage, from 0.200% to 0.350%. The Company is also required to pay customary letter of credit fees, as necessary.

On December 17, 2021, the Company amended the Credit Facility to expand the process for issuing letters of credit and the related invoicing, particularly with respect to letters of credit not denominated in U.S. Dollars.

As of December 31, 2022, the Company did not have an outstanding debt balance under the Credit Facility. Availability under the Credit Facility was $445 million as of December 31, 2022, which is net of outstanding letters of credit of $5 million. The Credit Facility matures, and all outstanding amounts become due and payable, on June 15, 2026.

The Credit Facility contains customary conditions to borrowings, events of default and covenants, including covenants that restrict the Company’s ability to sell assets, make changes to the nature of the Company’s business, engage in mergers or acquisitions, incur, assume or permit to exist additional indebtedness and guarantees, create or permit to exist liens, pay dividends, issue equity instruments, make distributions or redeem or repurchase capital stock or make other investments, engage in transactions with affiliates and make payments in respect of subordinated debt. The Credit Facility also requires the Company to maintain compliance with a maximum ratio of consolidated funded debt to consolidated EBITDA of 3.50 to 1.00. As of December 31, 2022, the Company was in compliance with all covenants.

Subsequent to December 31, 2022, the Company amended its Credit Facility (the “Amended Credit Facility”) to transition from a variable interest rate based on LIBOR to a variable interest rate based on the secured overnight financing rate (“SOFR”). After giving effect to that amendment, loans under the Amended Credit Facility bear interest at a rate equal to, at the Company’s option, an annual rate of either an Amended Base Rate or an adjusted term SOFR rate (defined as SOFR for a specified term plus a credit spread adjustment of 10 basis points, subject to a 0% floor), plus an applicable margin (“Amended Base Rate Borrowings” and “Term SOFR Borrowings”). The Amended Base Rate is defined as a rate per annum for any day equal to the greatest of (1) the rate of interest last quoted by The Wall Street Journal as the “Prime Rate” in the United States, (2) the NYFRB Rate in effect on such day plus half of 1% and (3) the adjusted term SOFR rate for a one-month interest period on such day plus 1%. The applicable margin is between 0.25% to 1.25% for Amended Base Rate Borrowings and between 1.25% and 2.25% for Term SOFR Borrowings based on the Company maintaining certain leverage ratios. The Company has had no drawdowns on its Credit Facility since December 31, 2022.

Note 9—Capitalization

The Class A and Class B common stock have the same rights and preferences including rights to dividends, except the Class B is entitled to ten votes per share and the Class A is entitled to one vote per share. Each share of Class B common stock is convertible into one share of Class A common stock at any time at the option of the holder. In addition, each share of Class B common stock will convert automatically into one share of Class A common stock upon any transfer, except for certain transfers described in the Company’s restated certificate of incorporation, including, without limitation, certain transfers for tax and estate planning purposes. The Company’s certificate of incorporation provides that all Class B common stock will convert automatically into Class A common stock on December 22, 2025 unless converted prior to such date.

The Company’s board of directors has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.

In February 2023, the Company's board of directors authorized and approved a share repurchase program of up to $700 million of the Company’s outstanding shares of Class A common stock, with no expiration date. Share repurchases under the program may be made from time to time, in the open market, in privately negotiated transactions and otherwise, at the discretion of management of the Company and in accordance with applicable federal securities laws, including Rule 10b-18 of the Exchange Act, and other applicable legal requirements. Such repurchases may also be made in compliance with Rule 10b5-1 trading plans entered into by the Company.

For the years ended December 31, 2022, 2021 and 2020, the Company recognized tax benefits on total stock-based compensation expense, which are reflected in the provision for income taxes in the consolidated statements of operations, of $48 million, $104 million and $135 million, respectively. For the years ended December 31, 2022, 2021 and 2020, tax benefit realized related to restricted stock vested and stock options exercised during the period was $72 million, $121 million and $151 million, respectively.

Stock-Based Award Plans

The Company is authorized to issue stock options, restricted stock awards, restricted stock units, stock appreciation rights and other stock-based and cash-based awards under its 2016 Incentive Award Plan. As of December 31, 2022, 69.0 million shares remained available for grant under the Company’s 2016 Incentive Award Plan. The number of shares authorized for grant is subject to increase each year on January 1, equal to the lesser of (a) 4% of the common stock outstanding (on an as-converted basis) on the final day of the immediately preceding calendar year and (b) such smaller number of shares as determined by the board of directors. On January 1, 2023, the number of shares authorized for grant under the Company’s 2016 Incentive Award Plan was increased by 19.6 million shares in accordance with plan provisions.

Stock Options

Stock options granted under the Company’s stock incentive plans generally vest over four years, subject to the holder’s continued service through the vesting date and expire no later than 10 years from the date of grant.

The following summarizes stock option activity:

			Shares Under Option (in thousands)						Weighted- Average Exercise Price						Weighted- Average Contractual Life (years)						Aggregate Intrinsic Value (in thousands)
Outstanding as of December 31, 2021			18,984						$	15.14
Granted			1,543						60.78
Exercised			(4,497)						10.56
Expired/forfeited			(612)						45.73
Outstanding as of December 31, 2022			15,418						$	19.82					5.7						$	438,623
Exercisable as of December 31, 2022			12,308						$	12.46					5.1						$	414,290

The fair value of options on the date of grant was estimated based on the Black-Scholes option pricing model. The weighted-average assumptions used to value options granted to employees for the periods presented were as follows:

			Year Ended December 31,
			2022						2021						2020
Expected term (years)			6.0						6.0						6.0
Expected volatility			66.5		%				64.3		%				60.5		%
Risk-free interest rate			2.91		%				1.04		%				0.57		%
Estimated dividend yield			—		%				—		%				—		%

The weighted-average grant date fair value per share of stock options granted for the years ended December 31, 2022, 2021 and 2020 and were $37.65, $43.57 and $17.25, respectively. The total intrinsic value of options exercised during the years ended December 31, 2022, 2021 and 2020 were $232 million, $538 million and $595 million, respectively.

At December 31, 2022, the Company had unrecognized stock-based compensation relating to stock options of approximately $87 million, which is expected to be recognized over a weighted-average period of 2.2 years.

CEO Performance Option

In October 2021, the Company granted a market-based performance award to the Company’s Chief Executive Officer (the “CEO Performance Option”) under the Company’s 2016 Incentive Award Plan. If specified target goals for the

per share price of the Company’s Class A common stock (ranging from $90.00 to $340.00 per share) and certain other vesting conditions are satisfied, including the CEO’s continued service, the CEO may purchase up to a target amount of 16 million shares of Class A common stock, subject to adjustment as discussed in the following sentence, to be earned in eight equal tranches over a maximum term of 10 years. These target shares are subject to decrease or increase by up to 20% for each tranche based on the relative total shareholder return (“TSR”) of the Company’s Class A common stock as compared to the TSR of the Nasdaq-100 Index at each vesting tranche, for a maximum of 19.2 million shares. The CEO Performance Option has an exercise price of $68.29 per share and a grant-date fair value of approximately $819 million, which was expected to be expensed on a graded-vesting basis over a derived service period of approximately five years but may be accelerated if the vesting criteria are met prior to the estimated performance period.

The grant-date fair value was estimated based on a Monte Carlo valuation model using the following assumptions:

Expected volatility			63.4		%
Risk-free interest rate			1.55		%
Estimated dividend yield			—		%

The CEO Performance Option has a one-year holding period with respect to the sale or transfer of vested shares, with the exception that shares may be transferred during the holding period to cover withholding tax obligations in connection with such exercise and transfers to the CEO’s immediate family for estate planning purposes or in connection with charitable or philanthropic activities. Due to the holding period, the Company applies a discount to reflect the non-transferability of the shares.

At December 31, 2021, the CEO Performance Option had outstanding options of 19.2 million. No options were exercised, forfeited or expired during the fiscal year ended December 31, 2022. At December 31, 2022, the CEO Performance Option had outstanding options of 19.2 million with no aggregate intrinsic value and a weighted-average contractual life of 8.8 years. At December 31, 2022, the CEO Performance Option had 2.4 million exercisable options with no aggregate intrinsic value and a weighted-average contractual life of 8.8 years.

On December 10, 2021, the expense related to the first tranche of the award was accelerated due to early stock price achievement. Stock-based compensation expense of $158 million for the CEO Performance Option, including the accelerated tranche, was recorded as a component of general and administrative expense in the fourth quarter of 2021. No such acceleration occurred during the year ended December 31, 2022. Stock-based compensation expense of $262 million for the CEO Performance Option was recorded as a component of general and administrative expense during the year ended December 31, 2022. At December 31, 2022, the Company had unrecognized stock-based compensation relating to the CEO Performance Option of $399 million that is expected to be recognized over a weighted-average period of 2.3 years, assuming no acceleration of vesting.

Restricted Stock

Restricted stock awards generally vest over four years, subject to the holder’s continued service through the vesting date. The following summarizes restricted stock activity:

			Shares (in thousands)						Weighted- Average Grant Date Fair Value Per Share
Unvested as of December 31, 2021			5,597						$	51.54
Granted			6,746						58.95

Forfeited			(1,006)						59.86
Unvested as of December 31, 2022			8,747						$	57.41

At December 31, 2022, the Company had unrecognized stock-based compensation relating to restricted stock of approximately $463 million, which is expected to be recognized over a weighted-average period of 3.0 years.

Employee Stock Purchase Plan

In September 2016, the Company established an ESPP with 8.0 million shares of Class A common stock available for issuance. As of December 31, 2022, 10.8 million shares remained available for grant under this plan. The number of shares authorized for grant is subject to increase each year on January 1, equal to the lesser of (a) 8.0 million shares, (b) 1% of the Class A common stock outstanding (on an as-converted basis) on the final day of the immediately preceding calendar year, and (c) such smaller number of shares as determined by the Company’s board of directors. On January 1, 2023, the number of shares available for issuance under the Company’s ESPP increased by 4.5 million shares in accordance with plan provisions.

Under the ESPP, all eligible employees are permitted to authorize payroll deductions of up to 100% of their compensation to purchase shares of Class A common stock, subject to applicable ESPP and statutory limits. The ESPP provides for offering periods generally up to two years, with purchases occurring and new offering periods commencing generally every six months. ESPP purchases generally occur on May 15th and November 15th each year. At each purchase date, employees are able to purchase shares at 85% of the lower of (1) the closing market price per share of Class A common stock on the employee’s enrollment into the applicable offering period and (2) the closing market price per share of Class A common stock on the purchase date. The ESPP has an automatic reset feature, whereby the offering period resets if the fair value of the Company’s common stock on a purchase date is less than that on the original offering date.

The fair value of ESPP shares was estimated using the Black-Scholes option pricing model with the following weighted-average assumptions:

			Year Ended December 31,
			2022						2021						2020
Expected term (years)			1.0						0.6						0.6
Expected volatility			74.1		%				62.3		%				61.9		%
Risk-free interest rate			2.53		%				0.09		%				0.40		%
Estimated dividend yield			—		%				—		%				—		%

The ESPP has a six-month holding period with respect to common stock purchases. Due to the holding period, the Company applies a discount to reflect the non-transferability of the shares. Stock-based compensation expense related to ESPP was $50 million, $62 million and $33 million for the years ended December 31, 2022, 2021 and 2020, respectively. At December 31, 2022, the Company had unrecognized stock-based compensation relating to ESPP awards of approximately $9 million, which is expected to be recognized over a weighted-average period of 0.9 years.

As of each reporting date, the Company’s management considers new evidence, both positive and negative, that could impact management’s view with regard to future realization of deferred tax assets. During 2022, management recorded an additional valuation allowance of $20 million against its U.K. net deferred tax assets, based on the history of cumulative losses and the conclusion that future taxable profit may not be available for the utilization of the deferred tax assets for U.K. income tax purposes.

As of December 31, 2022, the Company had federal, state and foreign net operating loss carryforwards of approximately $4 million, $39 million and $774 million, respectively. The federal, state and foreign net operating loss carryforwards are subject to limitations under applicable federal, state and foreign tax law. Federal net operating loss carryforward will carry forward indefinitely. State net operating loss carryforwards will begin to expire in 2040. Foreign net operating losses carry forward indefinitely.

As of December 31, 2022, the Company had state and foreign research and development tax credits of approximately $27 million and $1 million, respectively, which can be carried forward as prescribed under applicable state and foreign tax law. State and foreign research and development tax credits carry forward indefinitely.

As of December 31, 2022, unremitted earnings of the subsidiaries outside of the United States were approximately $5 million, on which no state taxes have been paid. The Company’s intention is to indefinitely reinvest these earnings outside the United States upon distribution of those earnings in the form of a dividend or otherwise, the Company would be subject to both state income taxes and withholding taxes payable to various foreign countries. The amounts of such tax liabilities that might be payable upon repatriation of foreign earnings are not material.

As of December 31, 2022, the Company had gross unrecognized tax benefits of approximately $91 million, $70 million of which is a reduction to deferred tax assets and the remaining $21 million which would affect the Company’s effective tax rate if recognized. As of December 31, 2021, the Company had gross unrecognized tax benefits of approximately $86 million, $85 million of which is a reduction to deferred tax assets and the remaining $2 million which would affect the Company’s effective tax rate if recognized.

Guarantees and Indemnification

In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to clients, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with directors and certain officers and employees that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. No demands have been made upon the Company to provide indemnification under such agreements, and thus, there are no claims that the Company is aware of that could have a material effect on the Company’s balance sheet, statement of operations or statement of cash flows. Accordingly, no amounts for any obligation have been recorded as of December 31, 2022 and 2021.

Litigation

From time to time, the Company is subject to various legal proceedings, litigation and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings, litigation and claims cannot be predicted with certainty, management does not believe that any of these proceedings or other claims will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows. 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.

On May 27, 2022, a stockholder of the Company filed a derivative lawsuit captioned Huizenga v. Green, et al., No. 2022-0461, asserting claims on behalf of the Company against certain members of the Company’s board of directors in the Court of Chancery of the State of Delaware. On June 27, 2022, a second derivative lawsuit captioned Pfeiffer v. Green, et al., No. 2022-0560 was filed in the Court of Chancery of the State of Delaware alleging substantially similar claims. The Company expects these lawsuits eventually will be consolidated. The two complaints allege generally that the Defendants breached their fiduciary duties to the Company and its stockholders in connection with the negotiation and approval of the CEO Performance Option. The plaintiffs seek a court order rescinding the CEO Performance Option and monetary

damages. On November 10, 2022, the plaintiffs filed a consolidated complaint, and on January 12, 2023, the Defendants moved to dismiss the consolidated complaint.

Litigation is inherently uncertain and there can be no assurance regarding the likelihood that the motions to dismiss or defense of the various actions will be successful.

Employment Contracts

The Company has entered into agreements with severance terms with certain employees and officers, all of whom are employed on an at-will basis, subject to certain severance obligations in the event of certain involuntary terminations. The Company may be required to accelerate the vesting of certain stock options in the event of changes in control, as defined and involuntary terminations.
