THE TRADE DESK, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1—Nature of Operations

The Trade Desk, Inc. (the “Company”) was formed in November 2009 as a Delaware corporation. The Company is headquartered in Ventura, California and has offices in various cities in North America, Europe, Asia and Australia. The Company is a technology company that empowers buyers of advertising by providing a self-service cloud-based platform on which ad buyers can create, manage, and optimize more expressive data-driven digital advertising campaigns across ad formats, including display, video, audio, native and social, on a multitude of devices, such as computers, mobile devices, and connected TV.

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

The accompanying condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and are unaudited. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. The condensed consolidated balance sheet as of December 31, 2020 was derived from audited financial statements but does not include all disclosures required by GAAP. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in its Annual Report on Form 10-K for the year ended December 31, 2020.

There have been no material changes to the Company’s accounting policies from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2020, and these unaudited interim condensed consolidated financial statements have been prepared on a basis consistent with that used to prepare the Company’s audited annual consolidated financial statements for the year ended December 31, 2020, and include, in the opinion of management, all adjustments, consisting of normal recurring items, necessary for the fair statement of the condensed consolidated financial statements.

The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results expected for the full year ending December 31, 2021.

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 condensed 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from these estimates.

As of September 30, 2021, the impact of the Coronavirus pandemic (“COVID-19”) on the Company’s business continued to evolve. As a result, many of the Company’s estimates and assumptions, including the allowance for credit losses, consider macro-economic 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.

For the three and nine months ended September 30, 2021, the Company’s assessment of credit losses considered business and market disruptions caused by COVID-19 and estimates of defaults by industry. The Company reviews the allowance for credit losses and financial implications of COVID-19 on expected 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.

7

Business Combinations

The results of a business combination are included in the Company’s condensed 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 $17.8 million, subject to purchase price adjustments. The purchase consideration was primarily attributable to non-deductible goodwill of $11.4 million, with the remainder allocated to acquired technology and other assets.

Recent Accounting Pronouncements 

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate or by another reference rate expected to be discontinued. The amendments are effective for all entities through December 31, 2022 and can be adopted as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020. The adoption of the amendment did not have a material impact on the Company’s condensed consolidated financial statements.

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 6—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 $450.0 million revolving loan facility, with a $20.0 million sublimit for swingline borrowings and a $15.0 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 $300.0 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.

Loans under the credit facility bear 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 LIBOR rate, plus an applicable margin (“Base Rate Borrowings” and “LIBOR Rate Borrowings”). The 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 LIBOR rate for a one month interest period on such day plus 1%. The applicable margin is 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.

As of September 30, 2021, the Company did not have an outstanding debt balance under the credit facility. Availability under the credit facility was $443.9 million as of September 30, 2021, which is net of outstanding letters of credit of $6.1 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 September 30, 2021, the Company was in compliance with all covenants.

Employee Stock Purchase Plan (“ESPP”)

Stock-based compensation expense related to the ESPP totaled $4.1 million and $3.7 million for the three months ended September 30, 2021 and 2020, respectively. Stock-based compensation expense related to the ESPP totaled $46.1 million and $17.8 million for the nine months ended September 30, 2021 and 2020, respectively. 

Note 8—Income Taxes

In determining the interim income tax provision for the nine months ended September 30, 2021, the Company utilized the annual estimated effective tax rate applied to the actual year-to-date income and added the tax effects of any discrete items in the reporting period in which they occur. In determining the interim benefit from income taxes for the nine months ended September 30, 2020, the Company utilized the discrete effective tax rate method, as allowed by Accounting Standards Codification (“ASC”) 740-270-30-18, “Income Taxes – Interim Reporting”.

For the three months ended September 30, 2021 and 2020, the income tax provision included benefits associated with stock-based awards in the amounts of $21.9 million and $25.6 million, respectively. For the nine months ended September 30, 2021 and 2020, the provision for (benefit from) income taxes included benefits associated with stock-based awards in the amounts of $58.2 million and $98.7 million, respectively.

For the nine months ended September 30, 2021, and 2020, the Company’s effective tax rate differed from the United States federal statutory tax rate of 21% primarily due to the impact of tax benefits associated with stock-based awards, nondeductible stock-based compensation, state and foreign taxes, and research and development tax credits.

On June 10, 2021, the UK Finance Act 2021 was enacted, increasing the corporate tax rate from 19% to 25%. Accordingly, the Company increased its net UK deferred tax assets by $76.4 million, which was fully offset by a valuation allowance.

There were no material changes to the Company’s unrecognized tax benefits during the nine months ended September 30, 2021, and the Company does not expect to have any significant changes to unrecognized tax benefits through the end of the fiscal year.

Note 9—Geographic Information

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”). The Company generally bills clients for the gross amount of Supplier Features they purchase through its platform and the platform fees, net of allowances (“Gross Billings”). The Company’s accounts receivable are recorded at the amount of Gross Billings for the amounts it is responsible to collect, and accounts payable are 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.

11

Gross Billings, set forth as a percentage, based on the billing address of the clients or client affiliates, were as follows:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2021			2020			2021			2020
U.S.		87	%		86	%		86	%		86	%

Total		100	%		100	%		100	%		100	%

Note 10— Commitments and Contingencies

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 its balance sheet, statement of income or statement of cash flows. Accordingly, no amounts for any obligation have been recorded at September 30, 2021.

Litigation

From time to time, the Company is subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings 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.

On June 28, 2021, a class action lawsuit was filed against the Company, the members of the Company’s board of directors, and one of the Company’s executive officers (collectively, the “Defendants”) in the Court of Chancery of the State of Delaware. The complaint alleges generally that the Defendants breached their fiduciary duties to the Company’s stockholders in connection with the negotiation and approval of the amendments to the Company’s certificate of incorporation and related matters voted on at the Special Meeting of Stockholders held on December 22, 2020 (the “Amendments”). Plaintiff seeks a court order rescinding the Amendments, as well as monetary damages. On August 27, 2021, the Defendants moved to dismiss the complaint. On October 8, 2021, the plaintiff filed an opposition to Defendants’ motion to dismiss the complaint. The Company believes that all of the claims asserted in the complaint are without merit and intends to defend against them vigorously. However, litigation is inherently uncertain and there can be no assurance regarding the likelihood that the Defendants’ defense of the action 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-based awards in the event of changes in control, as defined, and involuntary terminations.

Note 11— Subsequent Event 

On October 6, 2021, the Company granted a market-based performance award (the “Performance Option”) to the Company’s Chief Executive Officer (the “CEO”) 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, the CEO may purchase up to 16,000,000 shares of Class A common stock, to be earned in eight equal tranches, 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. The Performance Option has an exercise price of $68.29 per share and a grant-date fair value of approximately $819.0 million, which is expected to be expensed on a graded-vesting basis over a period of approximately five years but may be accelerated if the vesting criteria is met prior to the estimated performance period. Stock-based compensation expense for the Performance Option will be recorded as a component of general and administrative expense in the Company’s consolidated statement of operations beginning in the fourth quarter of 2021 and, assuming no acceleration of vesting, will be recognized over a weighted-average period of 2.9 years.

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

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Forward-looking statements generally relate to future events or our future financial or operating performance and may include statements concerning, among other things, our business strategy (including anticipated trends and developments in, and management plans for, our business and the markets in which we operate), financial results, the impact of COVID-19 on our business, operations, and the markets and communities in which we, our clients, and partners operate, results of operations, revenues, operating expenses, and capital expenditures, sales and marketing initiatives and competition. In some cases, you can identify forward-looking statements because they contain words such as “may,” “might,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “suggests,” “potential” or “continue” or the negative of these words or other similar terms or expressions that concern our expectations, strategy, plans or intentions. These statements are not guarantees of future performance; they reflect our current views with respect to future events and are based on assumptions and are subject to known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from expectations or results projected or implied by forward-looking statements.

We discuss many of these risks in Part II of this Quarterly Report on Form 10-Q in greater detail under the heading “Risk Factors” and in other filings we make from time to time with the Securities and Exchange Commission (the “SEC”). Also, these forward-looking statements represent our estimates and assumptions only as of the date of this Quarterly Report on Form 10-Q, which are inherently subject to change and involve risks and uncertainties. Unless required by federal securities laws, we assume no obligation to update any of these forward-looking statements, or to update the reasons actual results could differ materially from those anticipated, to reflect circumstances or events that occur after the statements are made. Given these uncertainties, investors should not place undue reliance on these forward-looking statements.

Investors should read this Quarterly Report on Form 10-Q and the documents that we reference in this report and have filed with the SEC, including our Annual Report on Form 10-K for the year ended December 31, 2020, completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.

References to “Notes” are notes included in our unaudited condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

Overview

We are a technology company that empowers buyers of advertising. Through our 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 display, video, audio, native and social, on a multitude of devices, such as computers, mobile devices, and connected TV (“CTV”). Our platform’s integrations with major inventory, publisher, and data partners provides ad buyers reach and decisioning capabilities, and our enterprise application programming interfaces (“APIs”) enable our clients to develop on top of the platform.

We commercially launched our platform in 2011, targeting the display advertising channel. Since launching, we have added additional advertising channels. The gross spend on our platform comes from multiple channels, including mobile, video (which includes CTV), display, audio, native and social channels.

Our clients are primarily the advertising agencies and other service providers for advertisers, with whom we enter into ongoing master services agreements (“MSAs”). We generate revenue by charging our clients a platform fee based on a percentage of a client’s total spend on advertising. We also generate revenue from providing data and other value-added services and platform features.

Executive Summary

Highlights

For the three months ended September 30, 2021 and 2020:

• revenue was $301.1 million and $216.1 million, respectively, representing an increase of 39%; and

• net income was $59.4 million and $41.2 million, respectively.

For the nine months ended September 30, 2021 and 2020:

• revenue was $800.9 million and $516.1 million, respectively, representing an increase of 55%; and

• net income was $129.7 million and $90.4 million, respectively.

Trends, Opportunities and Challenges

The growing digitization of media and fragmentation of audiences has increased the complexity of advertising, and thereby increased the need for automation in ad buying, which we provide on our platform. In order to grow, we will need to continue to develop our platform’s programmatic capabilities and advertising inventory. We believe that key opportunities include our ongoing global expansion, continuing development of our CTV, video, audio, and native ad inventory, and continuing development of data usage and advertising targeting capabilities.

We believe that growth of the programmatic advertising market is important for our ability to grow our business. Adoption of programmatic advertising by advertisers allows us to acquire new clients and grow revenue from existing clients. Although our clients include some of the largest advertising agencies in the world, we believe there is significant room for us to expand further within these clients and gain a larger amount of their advertising spend through our platform. We also believe that the industry trends noted above will lead to advertisers adopting programmatic advertising through platforms such as ours.

Similarly, the adoption of programmatic advertising by inventory owners and content providers allows us to expand the volume and type of advertising inventory that we present to our clients. For example, we have expanded our CTV, native and audio advertising offerings through our recent integrations with supply-side partners.

We invest for long-term growth. We anticipate that our operating expenses will continue to increase significantly in the foreseeable future as we invest in platform operations and technology and development to enhance our product features, including programmatic buying of CTV ad inventory, and in sales and marketing to acquire new clients and reinforce our relationships with existing clients. In addition, we expect to continue making investments in our infrastructure, including our information technology, financial and administrative systems and controls, to support our growing operations.

We believe the markets outside of the United States, and in particular China, offer an opportunity for growth, although such markets may also pose challenges related to compliance with local laws and regulations, restrictions on foreign ownership or investment, uncertainty related to trade relations, and a variety of additional risks. We intend to make additional investments in sales and marketing and product development to expand in these markets, including China, where we are making significant investments in our platform and growing our team.

We believe that these investments will contribute to our long-term growth, although they may negatively impact profitability in the near term.

Our business model has allowed us to grow significantly, and we believe that our operating leverage enables us to support future growth profitably.

COVID-19

The worldwide spread of the COVID-19 pandemic has resulted, and may continue to result, in a global slowdown of economic activity, which may decrease demand for a broad variety of goods and services, including those provided by our clients, while also disrupting supply channels, sales channels and advertising and marketing activities for an unknown period of time until the COVID-19 pandemic is contained, or economic activity normalizes. With the current uncertainty in economic activity, the impact on our revenue and our results of operations is likely to continue, the size and duration of which we are currently unable to accurately predict. The extent of the impact of the COVID-19 pandemic on our operational and financial performance will depend on a variety of factors, including the duration and spread of the COVID-19 pandemic and its impact on our clients, partners, industry, and employees, all of which are uncertain at this time and cannot be accurately predicted. See “Risk Factors” for further discussion of the adverse impacts of the COVID-19 pandemic on our business.

The increase in revenue for the three and nine months ended September 30, 2021, compared to the same prior year period, was primarily due to increases in gross spend in the current year on our platform by existing clients, which was driven by increases in the number of advertising campaigns executed per client.

The increase in platform operations expense for the three months ended September 30, 2021, compared to the same prior year period, was primarily due to increases of $3.6 million in personnel costs, including $0.9 million in stock-based compensation, $3.0 million in hosting costs and $1.8 million in facilities costs and allocated overhead. The increase in personnel costs was due to an increase in headcount. The increase in hosting costs was primarily attributable to increased support for the increased use of our platform by our clients. The increase in facilities costs was primarily driven by new data center locations and leases for additional office space to support our future growth.

The increase in platform operations expense for the nine months ended September 30, 2021, compared to the same prior year period, was primarily due to increases of $13.1 million in personnel costs, including $6.2 million of stock-based compensation, $7.8 million in hosting costs and $7.4 million in facilities costs and allocated overhead. These increases were primarily attributable to the factors described above.

We expect platform operations expenses to increase in absolute dollars in future periods as we continue to experience increased volumes of media impressions through our platform and hire additional personnel to support our clients.

The increase in sales and marketing expense for the three months ended September 30, 2021, compared to the same prior year period, was primarily due to increases of $10.3 million in personnel costs, including $2.2 million of stock-based compensation, $2.8 million in advertising and marketing costs and $1.5 million in allocated facilities costs. The increase in personnel costs was primarily due to an increase in headcount in order to support our sales efforts and continue to develop and maintain relationships with our clients, as well as an increase in incentive compensation. The increase in advertising and marketing costs was primarily due to an increase in marketing campaigns and sponsorships. The increase in allocated facilities costs was primarily driven by new leases for additional office space to support our future growth.

The increase in sales and marketing expense for the nine months ended September 30, 2021, compared to the same prior year period, was primarily due to increases of $50.0 million in personnel costs, including $18.8 million of stock-based compensation, $5.7 million in allocated facilities costs and $5.0 million in advertising and marketing costs. These increases were primarily attributable to the factors described above.

We expect sales and marketing expenses to increase in absolute dollars in future periods, as we focus on increasing the adoption of our platform with existing and new clients and expanding our international business.

The increase in technology and development expense for the three months ended September 30, 2021, compared to the same prior year period, was primarily due to increases of $13.4 million in personnel costs, including $3.4 million of stock-based compensation and $1.2 million in allocated facilities costs. The increase in personnel costs was primarily attributable to increased headcount to maintain and support further development of our platform. The increase in allocated facilities costs was primarily driven by new leases for additional office space to support our growth.

The increase in technology and development expense for the nine months ended September 30, 2021, compared to the same prior year period, was primarily due to increases of $39.9 million in personnel costs, including $17.0 million of stock-based compensation, and $5.5 million in allocated facilities costs. These increases were primarily attributable to the factors described above.

We expect technology and development expense to increase in absolute dollars as we continue to invest in the development of our platform to support additional features and functions, increase the number of advertising and data inventory suppliers and support the increase in volume of advertising spending by our customers on our platform. We also intend to invest in technology to further automate our business processes.

The increase in general and administrative expense for the three months ended September 30, 2021, compared to the same prior year period, was primarily due to increases of $6.7 million in personnel costs, including $1.2 million in stock-based compensation, and $1.5 million in allocated facilities costs. The increase in personnel costs was primarily due to our hiring and growth. The increase in allocated facilities costs was primarily driven by new leases for additional office space to support our future growth.

The increase in general and administrative expense for the nine months ended September 30, 2021, compared to the same prior year period, was primarily due to increases of $33.5 million in personnel costs, including $16.3 million of stock-based compensation, and $5.0 million in allocated facilities costs. These increases in personnel costs and allocated facilities costs were primarily attributable to the factors described above.

We expect general and administrative expenses to increase primarily due to an increase in stock-based compensation expense associated with the Performance Option and continued investment in corporate infrastructure to support growth. For additional information regarding the Performance Option, refer to Note11— Subsequent Event.

The increase in total other expense, net for the three months ended September 30, 2021, compared to the same prior year period, was primarily due to a net increase in foreign exchange losses.

The increase in total other expense, net for the nine months ended September 30, 2021, compared to the same prior year period, was primarily due to lower interest income on our short-term investments.

The U.S. federal statutory tax rate was 21% for the 2021 and 2020 periods, respectively.

The increase in the income tax provision for the three months ended September 30, 2021, compared to the same prior year period, was primarily due to higher pre-tax profitability coupled with the tax impacts associated with nondeductible stock-based compensation. Additionally, the 2020 period included an income tax benefit attributable to a net operating loss (“NOL”) carryback provided for under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) not applicable to the 2021 period. For the three months ended September 30, 2021, and 2020, the tax benefits associated with employee exercises of stock options and vesting of restricted stock units were $21.9 million and $25.6 million, respectively.

The increase in the income tax provision for the nine months ended September 30, 2021, compared to the same prior year period, was primarily due to higher pre-tax profitability coupled with the tax impacts associated with nondeductible stock-based compensation. Additionally, the 2020 period included an income tax benefit attributable to an NOL carryback provided for under the CARES Act not applicable to the 2021 period. For the nine months ended September 30, 2021 and 2020, the tax benefits associated with employee exercises of stock options and vesting of restricted stock units were $58.2 million and $98.7 million, respectively.

Liquidity and Capital Resources

As of September 30, 2021, we had cash and cash equivalents of $576.9 million, including cash of $41.0 million held by our international subsidiaries, short-term investments in marketable securities of $221.7 million, and working capital of $1,088.0 million.

We believe our existing cash and cash equivalents and cash flow from operations will be sufficient to meet our working capital requirements for at least the next 12 months. Further, in November 2020, we filed a shelf registration statement on Form S-3 with the SEC, (the “Shelf Registration”), which permits us to issue equity securities and equity-linked securities from time to time, subject to certain limitations. The Shelf Registration is intended to provide us with additional flexibility to access capital markets for general corporate purposes, subject to market conditions and our capital needs. Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth under “Risk Factors” within this Quarterly Report on Form 10-Q.

In the future, we may attempt to raise additional capital through the sale of equity securities or through equity-linked or debt financing arrangements. If we raise additional funds by issuing equity or equity-linked securities, the ownership of our existing stockholders will be diluted. If we raise additional financing by the incurrence of additional indebtedness, we may be subject to increased fixed payment obligations and could also be subject to additional restrictive covenants, such as limitations on our ability to incur additional debt, and other operating restrictions that could adversely impact our ability to conduct our business. Any future indebtedness we incur may result in terms that could be unfavorable to equity investors.

There can be no assurances that we will be able to raise additional capital. The inability to raise capital would adversely affect our ability to achieve our business objectives. In addition, if our operating performance during the next 12 months is below our expectations, our liquidity and ability to operate our business could be adversely affected. In light of the COVID-19 pandemic, we are closely monitoring the effect that current economic conditions may have on our working capital requirements.

Credit Facility

On June 15, 2021, we and a syndicate of banks, led by JPMorgan Chase Bank, N.A., as agent, entered into a Loan and Security Agreement (the “credit facility”). This agreement replaced our prior credit facility, which was scheduled to terminate in May 2022. The credit facility consists of a $450.0 million revolving loan facility, with a $20.0 million sublimit for swingline borrowings and a $15.0 million sublimit for the issuance of letters of credit. Under certain circumstances, we have the right to increase the credit facility by an amount not to exceed $300.0 million.

18

As of September 30, 2021, we did not have an outstanding debt balance under the credit facility. Availability under the credit facility was $443.9 million as of September 30, 2021, which is net of outstanding letters of credit of $6.1 million. The credit facility matures, and all outstanding amounts become due and payable, on June 15, 2026. As of September 30, 2021, we were in compliance with all covenants.

For additional information regarding the credit facility, refer to Note 6—Debt.

Cash Flows

The following table summarizes our cash flows for the periods presented:

	Nine Months Ended September 30,
	2021			2020
	(in thousands)
Net cash provided by operating activities	$	215,119		$	237,512
Net cash used in investing activities	$	(97,676	)	$	(60,906	)
Net cash provided by financing activities	$	22,120		$	126,889

Operating Activities

Our cash flows from operating activities are primarily influenced by growth in our operations, increases or decreases in collections from our clients, and related payments to our suppliers for advertising inventory and data. We typically pay suppliers in advance of collections from our clients. Our collection and payment cycles can vary from period to period. In addition, we expect seasonality to impact cash flows from operating activities on a sequential quarterly basis during the year.

For the nine months ended September 30, 2021, cash provided by operating activities of $215.1 million resulted primarily from net income adjusted for non-cash items of $333.9 million, partially offset by a net decrease in our operating assets and liabilities of $118.8 million. The net decrease was primarily due to a $48.6 million increase in accounts receivables, a $44.1 million decrease in accounts payable and a $31.9 decrease in operating lease liabilities. The increase in accounts receivable resulted from seasonality and the timing of cash receipts from clients. The decrease in accounts payable was due to the timing of payments to suppliers for the cost of advertising inventory, data and add-on features. The decrease in operating lease liabilities was due primarily to rent payments.

For the nine months ended September 30, 2020, cash provided by operating activities of $237.5 million resulted primarily from net income adjusted for non-cash items of $192.0 million and a net increase in our operating assets and liabilities of $45.5 million. The net increase was primarily due to a $21.1 million decrease in accounts receivables and a $47.7 million increase in accounts payable, partially offset by a $23.9 million increase in prepaid expenses and other assets. The decrease in accounts receivable resulted from seasonality, and the timing of cash receipts from clients. The increase in accounts payable was primarily due to the timing of payments to suppliers for the cost of advertising inventory, data, and add-on features. The increase in prepaid expenses and other assets was attributable to an increase in the income tax receivable primarily related to the tax benefits associated with employee exercises of stock options and vesting of restricted stock units.

Investing Activities

Our primary investing activities consist of investing in short-term investments in marketable securities, purchases of property and equipment for the expansion of our new facilities in support of our expanding headcount as a result of our growth, and capital expenditures to develop our software in support of enhancing our technology platform. As our business grows, we expect our capital expenditures and our investment activity to continue to increase.

For the nine months ended September 30, 2021, we used $97.7 million of cash in investing activities, consisting of $233.4 million to purchase short-term investments, $43.9 million to purchase property and equipment, $3.7 million of investments in capitalized software and $13.3 million for certain assets accounted for as a business acquisition, partially offset by maturities of short-term investments of $192.1 million and sales of investments of $4.5 million. Purchases of property and equipment and investments in capitalized software support our growth and further development of our platform.

For the nine months ended September 30, 2020, we used $60.9 million of cash in investing activities, consisting of $127.3 million to purchase short-term investments, $57.7 million to purchase property and equipment, and $4.2 million of investments in capitalized software, partially offset by maturities of short-term investments of $128.3 million. Purchases of property and equipment and investments in capitalized software support our growth and further development of our platform.

19

Financing Activities

For the nine months ended September 30, 2021, cash provided by financing activities of $22.1 million was primarily due to $39.6 million proceeds from stock option exercises and $22.8 million proceeds from our employee stock purchase plan, partially offset by $38.3 million of taxes paid for restricted stock award settlements and $1.9 million for debt financing costs.

For the nine months ended September 30, 2020, cash provided by financing activities of $126.9 million was primarily due to net proceeds of $72.0 million from our credit facility, $54.0 million proceeds from stock option exercises and $15.0 million proceeds from our employee stock purchase plan, partially offset by $14.2 million of taxes paid for restricted stock award settlements.

Off-Balance Sheet Arrangements

We do not have any relationships with other entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities that have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. We did not have any other off-balance sheet arrangements at September 30, 2021 other than the indemnification agreements described below.

Contractual Obligations

Our principal commitments consist of our non-cancelable operating leases for our various office facilities and other contractual commitments consisting of obligations to our hosting services providers, marketing contracts and providers of software as a service. In certain cases, the terms of the lease agreements provide for rental payments on a graduated basis.

The following table summarizes our non-cancelable contractual obligations at September 30, 2021:

	Payments Due by Period
	Less than 1 Year (Remaining 2021)		1-3 Years (2022 and 2023)		3-5 Years (2024 and 2025)		More than 5 Years (Thereafter)		Total
Operating lease commitments	$	13,476	$	103,260	$	82,506	$	131,430	$	330,672
Other contractual commitments		11,134		68,127		210		52		79,523
Total	$	24,610	$	171,387	$	82,716	$	131,482	$	410,195

In the ordinary course of business, we enter into agreements in which we may agree to indemnify clients, suppliers, vendors, lessors, business partners, lenders, stockholders, and other parties with respect to certain matters, including losses resulting from claims of intellectual property infringement, damages to property or persons, business losses, or other liabilities. Generally, these indemnity and defense obligations relate to our own business operations, obligations, and acts or omissions. However, under some circumstances, we agree to indemnify and defend contract counterparties against losses resulting from their own business operations, obligations, and acts or omissions, or the business operations, obligations, and acts or omissions of third parties. These indemnity provisions generally survive termination or expiration of the agreements in which they appear. In addition, we have entered into indemnification agreements with our directors, executive officers and other officers that will require us to indemnify them against liabilities that may arise by reason of their status or service as directors, officers or employees. In the ordinary course of business, demands have been made upon us to provide indemnification under such agreements, but we are not aware of any claims that could have a material effect on our balance sheet, statement of income or statement of cash flows. Accordingly, no amounts for any obligation have been recorded at September 30, 2021.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our actual results could differ from these estimates.

We believe that the assumptions and estimates associated with the evaluation of revenue recognition criteria, including the determination of revenue recognition as net versus gross in our revenue arrangements, stock-based compensation expense and income taxes have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results could differ materially from these estimates.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We have operations both within the United States and internationally, and we are exposed to market risks in the ordinary course of our business. These risks include primarily interest rate and foreign currency exchange risks.

Interest Rate Risk

We are exposed to market risk from changes in interest rates on our credit facility, which accrues interest at a variable rate. We have not used any derivative financial instruments to manage our interest rate risk exposure. Based upon the short-term investments amount as of September 30, 2021, a hypothetical one percentage point increase or decrease in the interest rate would result in a corresponding increase or decrease in investment income of approximately $2.2 million annually.

Foreign Currency Exchange Risk

We have foreign currency risks related to our revenue and expenses denominated in currencies other than the U.S. Dollar, principally the Euro, British Pound, Australian Dollar, Canadian Dollar, Japanese Yen and Indonesian Rupiah. The volatility of exchange rates depends on many factors that we cannot forecast with reliable accuracy. We have experienced and will continue to experience fluctuations in our net income as a result of transaction gains and losses related to remeasuring cash balances, trade accounts receivable and payable balances that are denominated in currencies other than the U.S. Dollar. The effect of an immediate 10% adverse change in foreign exchange rates on foreign-denominated accounts at September 30, 2021, would result in a foreign currency loss of approximately $22.9 million. In the event our non-U.S. Dollar denominated sales and expenses increase, our results of operations may be more greatly affected by fluctuations in the exchange rates of the currencies in which we do business.

We enter into forward contracts or other derivative transactions in an attempt to hedge our foreign currency risk. There can be no assurance that such transactions will be effective in hedging some or all of our foreign currency exposures and under some circumstances could generate losses for us.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), evaluated the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act, as of September 30, 2021. Our disclosure controls and procedures are designed to provide reasonable assurance that information we are required to disclose in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosures, and is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Based on this evaluation, our CEO and CFO have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of September 30, 2021.

Changes in Internal Control over Financial Reporting

During the quarter ended September 30, 2021, there have been no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Management recognizes that a control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud or error, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are not currently a party to any legal proceedings, litigation or claims, which, if determined adversely to us, would have a material adverse effect on our business, financial condition, results of operations or cash flows. We may from time to time, be party to litigation and subject to claims incident to the ordinary course of business. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

On June 28, 2021, a class action lawsuit was filed against us, the members of our board of directors, and one of our executive officers (collectively, the “Defendants”), in the Court of Chancery of the State of Delaware. The complaint alleges generally that the Defendants breached their fiduciary duties to our stockholders in connection with the negotiation and approval of the amendments to our certificate of incorporation and related matters voted on at the Special Meeting of Stockholders held on December 22, 2020. Plaintiff seeks a court order rescinding the amendments approved at the Special Meeting of Stockholders held on December 22, 2020, as well as monetary damages. On August 27, 2021, the Defendants moved to dismiss the complaint. On October 8, 2021, the plaintiff filed an opposition to Defendants’ motion to dismiss the complaint. We believe that all of the claims asserted in the complaint are without merit and intend to defend against them vigorously. However, litigation is inherently uncertain and there can be no assurance regarding the likelihood that the Defendants’ defense of the action will be successful.

Item 1A. Risk Factors

Investing in our Class A common stock involves a high degree of risk. You should consider carefully the risks and uncertainties described below, together with all of the other information contained in this Quarterly Report on Form 10-Q, including the condensed consolidated financial statements and the related notes and Management’s Discussion and Analysis of Financial Condition and Results of Operations, before making investment decisions related to our Class A common stock. If any of the following risks are realized, our business, financial condition, results of operations and prospects could be materially and adversely affected. In that event, the market price of our Class A common stock could decline and you could lose part or all of your investment.

Risks Related to Our Business and Industry

If we fail to maintain and grow our client base and spend through our platform, our revenue and business may be negatively impacted.

To sustain or increase our revenue, we must regularly add new clients and encourage existing clients to maintain or increase the amount of advertising inventory purchased through our platform and adopt new features and functionalities that we make available. If competitors introduce lower cost or differentiated offerings that compete with or are perceived to compete with ours, our ability to sell our services to new or existing clients could be impaired. We have spent significant effort in cultivating our relationships with advertising agencies, which has resulted in an increase in the budgets allocated to, and the amount of advertising purchased on, our platform. However, it is possible that we may reach a point of saturation at which we cannot continue to grow our revenue from such agencies because of internal limits that advertisers may place on the allocation of their advertising budgets to digital media to a particular provider or otherwise. While we generally have master services agreements (“MSAs”) in place with our clients, such agreements allow our clients to change the amount they spend through our platform or terminate our services with limited notice. We do not typically have exclusive relationships with our clients and there is limited cost to moving their media spend to our competitors. As a result, we have limited visibility to our future advertising revenue streams. We cannot assure you that our clients will continue to use our platform or that we will be able to replace, in a timely or effective manner, departing clients with new clients that generate comparable revenue. If a major client representing a significant portion of our business decides to materially reduce its use of our platform or to cease using our platform altogether, it is possible that our revenue or revenue growth rate could be significantly reduced, and our business negatively impacted.

The loss of advertising agencies as clients could significantly harm our business, financial condition and results of operations.

Our client base consists primarily of advertising agencies. We do not have exclusive relationships with advertising agencies, and we depend on agencies to work with us to build and maintain advertiser relationships and execute advertising campaigns.

The loss of agencies as clients could significantly harm our business, financial condition and results of operations. If we fail to maintain satisfactory relationships with an advertising agency, we risk losing business from the advertisers represented by that agency.

Advertisers may change advertising agencies. If an advertiser switches from an agency that utilizes our platform to one that does not, we will lose revenue from that advertiser. In addition, some advertising agencies have their own relationships with suppliers of advertising inventory and can directly connect advertisers with such suppliers. Our business may suffer to the extent that advertising agencies and inventory suppliers purchase and sell advertising inventory directly from one another or through intermediaries other than us.

22

We had approximately 875 clients, consisting primarily of advertising agencies, as of December 31, 2020. Many of these agencies are owned by holding companies, where decision making is decentralized such that purchasing decisions are made, and relationships with advertisers, are located, at the agency, local branch, or division level. If all of our individual client contractual relationships were aggregated at the holding company level, Publicis Groupe and WPP plc would have each represented more than 10% of our gross billings for 2020.

In most cases, we enter into separate contracts and billing relationships with the individual agencies and account for them as separate clients. However, some holding companies for these agencies may choose to exert control over the individual agencies in the future. If so, any loss of relationships with such holding companies and, consequently, of their agencies, local branches or divisions, as clients could significantly harm our business, financial condition, and results of operations.

If we fail to innovate or make the right investment decisions in our offerings and platform, we may not attract and retain advertisers and advertising agencies and our revenue and results of operations may decline.

Our industry is subject to rapid and frequent changes in technology, evolving client needs and the frequent introduction by our competitors of new and enhanced offerings. We must constantly make investment decisions regarding offerings and technology to meet client demand and evolving industry standards. We may make bad decisions regarding these investments. If new or existing competitors have more attractive offerings, we may lose clients or clients may decrease their use of our platform. New client demands, superior competitive offerings or new industry standards could require us to make unanticipated and costly changes to our platform or business model. In addition, as we develop and introduce new products and services, including those incorporating or utilizing artificial intelligence and machine learning and new processing of personal information, they may raise new, or heighten existing, technological, legal and other challenges, and may cause unintended consequences, may not function properly or may be misused by our clients. If we fail to adapt to our rapidly changing industry or to evolving client needs, or we provide new products and services that exacerbate technological, legal or other challenges, demand for our platform could decrease and our business, financial condition and results of operations may be adversely affected.

The market for programmatic buying for advertising campaigns is relatively new and evolving. If this market develops slower or differently than we expect, our business, growth prospects and financial condition would be adversely affected.

The substantial majority of our revenue has been derived from clients that programmatically purchase advertising inventory through our platform. We expect that spending on programmatic ad buying will continue to be our primary source of revenue for the foreseeable future and that our revenue growth will largely depend on increasing spend through our platform. The market for programmatic ad buying is an emerging market, and our current and potential clients may not shift to programmatic ad buying from other buying methods as quickly as we expect, which would reduce our growth potential. If the market for programmatic ad buying deteriorates or develops more slowly than we expect, it could reduce demand for our platform, and our business, growth prospects and financial condition would be adversely affected.

In addition, our revenue may not necessarily grow at the same rate as spend on our platform. As the market for programmatic buying for advertising matures, growth in spend may outpace growth in our revenue due to a number of factors, including pricing competition, quantity discounts and shifts in product, media, client and channel mix. A significant change in revenue as a percentage of spend could reflect an adverse change in our business and growth prospects. In addition, any such fluctuations, even if they reflect our strategic decisions, could cause our performance to fall below the expectations of securities analysts and investors, and adversely affect the price of our common stock.

The effects of health epidemics, such as the ongoing global COVID-19 pandemic, have had, and could in the future have, an adverse impact on our business, financial condition and results of operations.

Our business and operations have been and could in the future be adversely affected by health epidemics, such as the global COVID-19 pandemic. The COVID-19 pandemic and efforts to control its spread have curtailed the movement of people, goods and services worldwide, including in the regions in which we and our clients and partners operate, and have significantly impacted economic activity and financial markets. Many marketers have decreased or paused their advertising spending as a response to the economic uncertainty, decline in business activity, and other COVID-related impacts, which have negatively impacted, and may continue to negatively impact, our revenue and results of operations, the extent and duration of which we may not be able to accurately predict. In addition, our clients’ and advertisers’ businesses or cash flows have been and may continue to be negatively impacted by the COVID-19 pandemic, which has and may continue to lead them to seek adjustments to payment terms or delay making payments or default on their payables, any of which may impact the timely receipt and/or collectability of our receivables. Typically, we are contractually required to pay advertising inventory and data suppliers within a negotiated period of time, regardless of whether our clients pay us on time, or at all, and we may not be able to renegotiate better terms. As a result, our financial condition and results of operations may be adversely impacted.

23

Our operations are subject to a range of external factors related to the COVID-19 pandemic that are not within our control. We have taken precautionary measures intended to minimize the risk of the spread of the virus to our employees, partners and clients, and the communities in which we operate. A wide range of governmental restrictions has also been imposed on our employees, clients and partners’ physical movement to limit the spread of COVID-19. There can be no assurance that precautionary measures, whether adopted by us or imposed by others, will be effective, and such measures could negatively affect our sales, marketing, and client service efforts, delay and lengthen our sales cycles, decrease our employees’, clients’, or partners’ productivity, or create operational or other challenges, any of which could harm our business and results of operations.

The economic uncertainty caused by the COVID-19 pandemic has made and may continue to make it difficult for us to forecast revenue and operating results and to make decisions regarding operational cost structures and investments. We have committed, and we plan to continue to commit, resources to grow our business, including to expand our international presence, employee base, and technology development, and such investments may not yield anticipated returns, particularly if worldwide business activity continues to be impacted by the COVID-19 pandemic. The duration and extent of the impact from the COVID-19 pandemic depend on future developments that cannot be accurately predicted at this time, and if we are not able to respond to and manage the impact of such events effectively, our business may be harmed.

The market in which we participate is intensely competitive, and we may not be able to compete successfully with our current or future competitors.

We operate in a highly competitive and rapidly changing industry. We expect competition to persist and intensify in the future, which could harm our ability to increase revenue and maintain profitability. New technologies and methods of buying advertising present a dynamic competitive challenge, as market participants develop and offer new products and services aimed at capturing advertising spend or disrupting the digital marketing landscape, such as analytics, automated media buying and exchanges.

We may also face competition from new companies entering the market, including large established companies and companies that we do not yet know about or do not yet exist. If existing or new companies develop, market or resell competitive high-value products or services that result in additional competition for advertising spend or advertising inventory or if they acquire one of our existing competitors or form a strategic alliance with one of our competitors, our ability to compete effectively could be significantly compromised and our results of operations could be harmed.

Our current and potential competitors may have significantly more financial, technical, marketing, and other resources than we have, which may allow them to devote greater resources to the development, promotion, sale and support of their products and services. They may also have more extensive advertiser bases and broader publisher relationships than we have, and may be better positioned to execute on advertising conducted over certain channels, such as social media, mobile, and video. Some of our competitors may have a longer operating history and greater name recognition. As a result, these competitors may be better able to respond quickly to new technologies, develop deeper advertiser relationships or offer services at lower prices. Any of these developments would make it more difficult for us to sell our platform and could result in increased pricing pressure, increased sales and marketing expense, or the loss of market share.

We often have long sales cycles, which can result in significant time between initial contact with a prospect and execution of a client agreement, making it difficult to project when, if at all, we will obtain new clients and when we will generate revenue from those clients.

Our sales cycle, from initial contact to contract execution and implementation can take significant time. Our sales efforts involve educating our clients about the use, technical capabilities and benefits of our platform. Some of our clients undertake an evaluation process that frequently involves not only our platform but also the offerings of our competitors. As a result, it is difficult to predict when we will obtain new clients and begin generating revenue from these new clients. Even if our sales efforts result in obtaining a new client, under our usage-based pricing model, the client controls when and to what extent it uses our platform. As a result, we may not be able to add clients or generate revenue as quickly as we may expect, which could harm our revenue growth rates.

24

We are subject to payment-related risks that may adversely affect our business, working capital, financial condition and results of operations, including from advertising agencies that do not pay us until they receive payment from their advertisers and from clients that dispute or do not pay their invoices.

Spend on our platform primarily comes through our agency clients. Many of our contracts with advertising agencies provide that if the advertiser does not pay the agency, the agency is not liable to us, and we must seek payment solely from the advertiser, a type of arrangement called sequential liability. Contracting with these agencies, which in some cases have or may develop higher-risk credit profiles, may subject us to greater credit risk than if we were to contract directly with advertisers. This credit risk may vary depending on the nature of an advertising agency’s aggregated advertiser base. In addition, typically, we are contractually required to pay advertising inventory and data suppliers within a negotiated period of time, regardless of whether our clients pay us on time, or at all. In addition, we typically experience slow payment cycles by advertising agencies as is common in our industry. While we attempt to negotiate long payment periods with our suppliers and shorter periods from our clients, we are not always successful. As a result, we often face a timing issue with our accounts payable on shorter cycles than our accounts receivables, requiring us to remit payments from our own funds, and accept the risk of credit loss.

This collections and payments cycle may increasingly consume working capital if we continue to be successful in growing our business. If we are unable to borrow on commercially acceptable terms, our working capital availability could be reduced, and as a consequence, our financial condition and results of operations would be adversely impacted.

We may also be involved in disputes with clients, and in the case of agencies, their advertisers, over the operation of our platform, the terms of our agreements or our billings for purchases made by them through our platform. If we are unable to resolve disputes with our clients, we may lose clients or clients may decrease their use of our platform and our financial performance and growth may be adversely affected. If we are unable to collect or make adjustments to bills to clients, we could incur write-offs for credit loss, which could harm our results of operations. In the future, credit loss may exceed reserves for such contingencies and our credit loss exposure may increase over time. Any increase in write-offs for credit loss could harm our business, financial condition and results of operations. Even if we are not paid by our clients on time or at all, we are still obligated to pay for the advertising inventory, third-party data, and other add-on features that clients purchase on our platform, and as a consequence, our business, financial condition and results of operations would be adversely impacted.

Any decrease in the use of the advertising channels that we are primarily dependent upon, failure to expand the use of emerging channels, or unexpected shift in use among the channels in which we operate, could harm our growth prospects, financial condition and results of operations.

Historically, our clients have predominantly used our platform to purchase mobile, display and video advertising inventory. We expect that these will continue to be significant channels used by our clients for digital advertising in the future. We also believe that our revenue growth may depend on our ability to expand within social, native, audio, and in particular, CTV, and we have been, and are continuing to, enhance such channels. Any decrease in the use of mobile, display and video advertising, whether due to clients losing confidence in the value or effectiveness of such channels, regulatory restrictions or other causes, or any inability to further penetrate social, native, audio, CTV or enter new and emerging advertising channels, could harm our growth prospects, financial condition and results of operations.

Each advertising channel presents distinct and substantial risk and, in many cases, requires us to continue to develop additional functionality or features to address the particular requirements of the channel. Our ability to provide capabilities across multiple advertising channels, which we refer to as omnichannel, may be constrained if we are not be able to maintain or grow advertising inventory for such channels, and some of our omnichannel offerings may not gain market acceptance. If we fail to maintain a diversified channel mix, a decrease in the demand for any channel or channels that we become primarily dependent upon could harm our business, financial condition and results of operations. We may not be able to accurately predict changes in overall advertiser demand for the channels in which we operate and cannot assure you that our investment in channel development will correspond to any such changes. Furthermore, if our channel mix changes due to a shift in client demand, such as clients shifting their spending more quickly or more extensively than expected to channels in which we have relatively less functionality, features, or inventory, then demand for our platform could decrease, and our business, financial condition, and results of operations could be adversely affected.

We may experience fluctuations in our results of operations, which could make our future results of operations difficult to predict or cause our results of operations to fall below analysts’ and investors’ expectations.

Our quarterly and annual results of operations have fluctuated in the past and we expect our future results of operations to fluctuate due to a variety of factors, many of which are beyond our control. Fluctuations in our results of operations could cause our performance to fall below the expectations of analysts and investors, and adversely affect the price of our common stock. Because our business is changing and evolving rapidly, our historical results of operations may not be necessarily indicative of our future results of operations. Factors that may cause our results of operations to fluctuate include the following:

• changes in demand for programmatic advertising and for our platform, including related to the seasonal nature of our clients’ spending on digital advertising campaigns;

25

• changes to availability of and pricing of competitive products and services, and their effects on our pricing;

• changes in the pricing or availability of data and other third-party services, including pricing structure changes and the alignment of our pricing model with our data partners;

• changes in our client base and platform offerings;

• the addition or loss of advertising agencies and advertisers as clients;

• changes in advertising budget allocations, agency affiliations or marketing strategies;

• changes to our product, media, client or channel mix;

• changes and uncertainty in the regulatory environment for us, advertisers or others in the advertising industry, and the effects of our efforts and those of our clients and partners to address changes and uncertainty in the regulatory environment;

• changes in the economic prospects of advertisers or the economy generally, which could alter advertisers’ spending priorities, or could increase the time or costs required to complete advertising inventory sales;

• changes in the pricing and availability of advertising inventory, including through real-time advertising exchanges or in the cost of reaching end consumers through digital advertising;

• disruptions or outages on our platform;

• factors beyond our control, such as natural disasters, terrorism, war and public health crises;

• the introduction of new technologies or offerings by our competitors or others in the advertising marketplace;

• changes in our capital expenditures as we acquire the hardware, equipment and other assets required to support our business;

• timing differences between our payments for advertising inventory and our collection of related advertising revenue;

• the length and unpredictability of our sales cycle;

• costs related to acquisitions of businesses or technologies and development of new products;

• cost of employee recruiting and retention; and

• changes to the cost of infrastructure, including real estate and information technology.

Based upon the factors above and others beyond our control, we have a limited ability to forecast our future revenue, costs and expenses. If we fail to meet or exceed the operating results expectations of analysts and investors or if analysts and investors have estimates and forecasts of our future performance that are unrealistic or that we do not meet, the market price of our common stock could decline. In addition, if one or more of the analysts who cover us adversely change their recommendation regarding our stock, the market price of our common stock could decline. In the past, companies that have experienced volatility in the market price of their stock have been subject to securities litigation. We may be the target of this type of litigation in the future, which could result in substantial costs and divert our management’s attention from other business concerns.

If our access to quality advertising inventory is diminished or fails to expand, our revenue could decline and our growth could be impeded.

We must maintain a consistent supply of attractive ad inventory. Our success depends on our ability to secure quality inventory on reasonable terms across a broad range of advertising networks and exchanges and social media platforms, including video, display, CTV, audio and mobile inventory. The amount, quality and cost of inventory available to us can change at any time. A few inventory suppliers hold a significant portion of the programmatic inventory either generally or concentrated in a particular channel, such as audio and social media. In addition, we compete with companies with which we have business relationships. For example, Google is one of our largest advertising inventory suppliers in addition to being one of our competitors. If Google or any other company with attractive advertising inventory limits our access to its advertising inventory, our business could be adversely affected. If our relationships with certain of our suppliers were to cease, or if the material terms of these relationships were to change unfavorably, our business would be negatively impacted. Our suppliers are generally not bound by long-term contracts. As a result, there is no guarantee that we will have access to a consistent supply of quality inventory on favorable terms. If we are unable to compete favorably for advertising inventory available on real-time advertising exchanges, or if real-time advertising exchanges decide not to make their advertising inventory available to us, we may not be able to place advertisements or find alternative sources of inventory with comparable traffic patterns and consumer demographics in a timely manner. Furthermore, the inventory that we access through real-time advertising exchanges may be of low quality or misrepresented to us, despite attempts by us and our suppliers to prevent fraud and conduct quality assurance checks.

26

Inventory suppliers control the bidding process, rules and procedures for the inventory they supply, and their processes may not always work in our favor. For example, suppliers may place restrictions on the use of their inventory, including prohibiting the placement of advertisements on behalf of specific advertisers. Through the bidding process, we may not win the right to deliver advertising to the inventory that is selected through our platform and may not be able to replace inventory that is no longer made available to us.

As new types of inventory become available, we will need to expend significant resources to ensure we have access to such new inventory. For example, although television advertising is a large market, only a very small percentage of it is currently purchased through digital advertising exchanges. We are investing heavily in our programmatic television offering, including by increasing our workforce and by adding new features, functions and integrations to our platform. If the CTV market does not grow as we anticipate or we fail to successfully serve such market, our growth prospects could be harmed.

Our success depends on consistently adding valued inventory in a cost-effective manner. If we are unable to maintain a consistent supply of quality inventory for any reason, client retention and loyalty, and our financial condition and results of operations could be harmed.

Economic downturns and market conditions beyond our control could adversely affect our business, financial condition and results of operations.

Our business depends on the overall demand for advertising and on the economic health of advertisers that benefit from our platform. Economic downturns or unstable market conditions may cause advertisers to decrease or pause their advertising budgets, which could reduce spend though our platform and adversely affect our business, financial condition and results of operations. As described above, public health crises may disrupt the operations of our customers and partners for an unknown period of time, including as a result of travel restrictions and/or business shutdowns, all of which could negatively impact our business and results of operations, including cash flows. As we explore new countries to expand our business, economic downturns or unstable market conditions in any of those countries could result in our investments not yielding the returns we anticipate.

Seasonal fluctuations in advertising activity could have a negative impact on our revenue, cash flow and results of operations.

Our revenue, cash flow, results of operations and other key operating and performance metrics may vary from quarter to quarter due to the seasonal nature of our clients’ spending on advertising campaigns. For example, clients tend to devote more of their advertising budgets to the fourth calendar quarter to coincide with consumer holiday spending. Moreover, advertising inventory in the fourth quarter may be more expensive due to increased demand for it. Political advertising could also cause our revenue to increase during election cycles and decrease during other periods. Our historical revenue growth has lessened the impact of seasonality; however, seasonality could have a more significant impact on our revenue, cash flow and results of operations from period to period if our growth rate declines, if seasonal spending becomes more pronounced, or if seasonality otherwise differs from our expectations.

Failure to manage our growth effectively could cause our business to suffer and have an adverse effect on our financial condition and results of operations.

We have experienced and continue to experience significant growth in a short period of time. To manage our growth effectively, we must continually evaluate and evolve our organization. We must also manage our employees, operations, finances, technology and development and capital investments efficiently. Our efficiency, productivity and the quality of our platform and client service may be adversely impacted if we do not train our new personnel, particularly our sales and support personnel, quickly and effectively, or if we fail to appropriately coordinate across our organization. Additionally, our rapid growth may place a strain on our resources, infrastructure and ability to maintain the quality of our platform. Our revenue growth and levels of profitability in recent periods should not be considered as indicative of future performance. In future periods, our revenue or profitability could decline or grow more slowly than we expect. Failure to manage our growth effectively could cause our business to suffer and have an adverse effect on our financial condition and results of operations.

As our costs increase, we may not be able to generate sufficient revenue to sustain profitability.

We have expended significant resources to grow our business in recent years by increasing the offerings of our platform, growing our number of employees and expanding internationally. Despite the initial decline in revenue in response to the COVID-19 pandemic, we anticipate continued growth that could require substantial financial and other resources to, among other things:

• develop our platform, including by investing in our engineering team, creating, acquiring or licensing new products or features, and improving the availability and security of our platform;

• continue to expand internationally by growing our sales force and client services team in an effort to increase our client base and spend through our platform, and by adding inventory and data from countries our clients are seeking;

27

• improve our technology infrastructure, including investing in internal technology development and acquiring outside technologies;

• expand our platform’s reach in new and growing channels such as CTV, including expanding the supply of CTV inventory;

• cover general and administrative expenses, including legal, accounting and other expenses necessary to support a larger organization;

• cover sales and marketing expenses, including a significant expansion of our direct sales organization;

• cover expenses relating to data collection and use and consumer privacy compliance, including additional infrastructure, product features, security, automation and personnel; and

• explore strategic acquisitions.

Investing in the foregoing, however, may not yield anticipated returns, especially during the period of impact from the COVID-19 pandemic. Consequently, as our costs increase, we may not be able to generate sufficient revenue to sustain profitability.

We allow our clients to utilize application programming interfaces (“APIs”), with our platform, which could result in outages or security breaches and negatively impact our business, financial condition and results of operations.

The use of APIs by our clients has significantly increased in recent years. Our APIs allow clients to build their own media buying and data management interface by using our APIs to develop custom integration of their business with our platform. The increased use of APIs increases security and operational risks to our systems, including the risk for intrusion attacks, data theft, or denial of service attacks. Furthermore, while APIs allow clients greater ease and power in accessing our platform, they also increase the risk of overusing our systems, potentially causing outages. We have experienced system slowdowns due to client overuse of our systems through our APIs. While we have taken measures intended to decrease security and outage risks associated with the use of APIs, we cannot guarantee that such measures will be successful. Our failure to prevent outages or security breaches resulting from API use could result in government enforcement actions against us, claims for damages by consumers and other affected individuals, costs associated with investigation and remediation damage to our reputation and loss of goodwill, any of which could harm our business, financial condition and results of operations.

We may experience outages and disruptions on our platform if we fail to maintain adequate security and supporting infrastructure as we scale our platform, which may harm our reputation and negatively impact our business, financial condition and results of operations.

As we grow our business, we expect to continue to invest in technology services and equipment, including data centers, network services and database technologies, as well as potentially increase our reliance on open source software. Without these improvements, our operations might suffer from unanticipated system disruptions, slow transaction processing, unreliable service levels, impaired quality or delays in reporting accurate information regarding transactions in our platform, any of which could negatively affect our reputation and ability to attract and retain clients. In addition, the expansion and improvement of our systems and infrastructure may require us to commit substantial financial, operational and technical resources, with no assurance our business will increase. If we fail to respond to technological change or to adequately maintain, expand, upgrade and develop our systems and infrastructure in a timely fashion, our growth prospects and results of operations could be adversely affected. The steps we take to increase the reliability, integrity and security of our platform as it scales are expensive and complex, and our execution could result in operational failures and increased vulnerability to cyberattacks. Such cyberattacks could include denial-of-service attacks impacting service availability (including the ability to deliver ads) and reliability, tricking company employees into releasing control of their systems to a hacker, or the introduction of computer viruses or malware into our systems with a view to steal confidential or proprietary data. Cyberattacks of increasing sophistication may be difficult to detect and could result in the theft of our intellectual property and data, including personal information, from our platform. We are also vulnerable to unintentional errors or malicious actions by persons with authorized access to our systems that exceed the scope of their access rights, distribute data erroneously, or, unintentionally or intentionally, interfere with the intended operations of our platform. Moreover, we could be adversely impacted by outages and disruptions in the online platforms of our inventory and data suppliers, such as real-time advertising exchanges. Outages and disruptions of our platform, including due to cyberattacks, may harm our reputation and negatively impact our business, financial condition and results of operations.

28

Operational performance and internal control issues with our platform, whether real or perceived, including a failure to respond to technological changes or to upgrade our technology systems, may adversely affect our business, financial condition and results of operations.

We depend upon the sustained and uninterrupted performance of our platform to manage our inventory supply; bid on inventory for each campaign; collect, process and interpret data; optimize campaign performance in real time; and provide billing information to our financial systems. If our platform cannot scale to meet demand, if there are errors in our execution of any of these functions on our platform or if we experience outages, then our business may be harmed. We may also face material delays in introducing new services, products and enhancements. If competitors introduce new products and services using new technologies or if new industry standards and practices emerge, our existing proprietary technology and systems may become obsolete.

Our platform is complex and multifaceted, and operational and performance issues could arise both from the platform itself and from outside factors. Errors, failures, vulnerabilities and bugs have been found in the past, and may be found in the future. Our platform also relies on third-party technology and systems to perform properly and is often used in connection with computing environments utilizing different operating systems, system management software, equipment and networking configurations, which may cause errors in, or failures of, our platform or such other computing environments. Operational and performance issues with our platform could include the failure of our user interface, outages, errors during upgrades or patches, discrepancies in costs billed versus costs paid, unanticipated volume overwhelming our databases, server failure, or catastrophic events affecting one or more server farms. While we have built redundancies in our systems, full redundancies do not exist. Some failures will shut our platform down completely, others only partially. Partial failures, which we have experienced in the past, could result in unauthorized bidding, cessation of our ability to bid or deliver impressions or deletion of our reporting, in each case resulting in unanticipated financial obligations or impact.

Operational, performance and internal control issues with our platform could also result in negative publicity, damage to our brand and reputation, loss of clients, loss of or delay in market acceptance of our platform, increased costs or loss of revenue, loss of the ability to access our platform, loss of competitive position, claims by clients for losses sustained by them and loss of stockholder confidence in the accuracy and completeness of our financial reports. Alleviating problems resulting from such issues could require significant expenditures of capital and other resources and could cause interruptions, delays or the cessation of our business, any of which may adversely affect our business, financial condition and results of operations.

If unauthorized access is obtained to user, client or inventory and third-party provider data, or our platform is compromised, our services may be disrupted or perceived as insecure, and as a result, we may lose existing clients or fail to attract new clients, and we may incur significant reputational harm and legal and financial liabilities.

Our products and services involve the storage and transmission of significant amounts of data from users, clients, and inventory and data providers, a large volume of which is hosted by third-party service providers. Our services and data could be exposed to unauthorized access due to activities that breach or undermine security measures, including: negligence or malfeasance by internal or external actors; attempts by outside parties to fraudulently induce employees, clients or vendors to disclose sensitive information in order to gain access to our data; or errors or vulnerabilities in our systems, products or processes or in those of our service providers, clients, and vendors. For example, from time to time, we experience cyberattacks of varying degrees and other attempts to obtain unauthorized access to our systems, including to employee mailboxes. We have dedicated and expect to continue to dedicate resources toward security protections that shield data from these activities. However, such measures cannot provide absolute security. Further, we can expect that the deployment of techniques to circumvent our security measures may occur with more frequency and sophistication and may not be recognized until launched against a target. Accordingly, we may be unable to anticipate or detect these techniques or to implement adequate preventative measures. Finally, while we have developed worldwide incident response teams and dedicated resources to incident response processes, such processes could, among other issues, fail to be adequate or accurately assess the incident severity, not proceed quickly enough, or fail to sufficiently remediate an incident.

A breach of our security and/or our failure to respond sufficiently to a security incident could disrupt our services and result in theft, misuse, loss, corruption, or improper use or disclosure of data. This could result in government investigations, enforcement actions and other legal and financial liability, and/or loss of confidence in the availability and security of our products and services, all of which could seriously harm our reputation and brand and impair our ability to attract and retain clients. As we launch new products and services, some of which involve the receipt and processing of identifiable information, the risk of breach to our systems increases, and we could be subject to contractual breach and indemnification claims from other clients and partners and otherwise suffer damage to our reputation, brand, and business. Our platform may also receive data in aggregated or pseudonymized form, and if our systems are breached and such data or information is compromised, it could be damaging to our brand, reputation, and business. Cyberattacks could also compromise our own trade secrets and other sensitive information and result in such information being disclosed to others and becoming less valuable, which could negatively affect our business.

29

Privacy and data protection laws to which we are subject may cause us to incur additional or unexpected costs, subject us to enforcement actions for compliance failures, or cause us to change our platform or business model, which may have a material adverse effect on our business.

Information relating to individuals and their devices (sometimes called “personal information” or “personal data”) is regulated under a wide variety of local, state, national, and international laws and regulations that apply to the collection, use, retention, protection, disclosure, transfer (including transfer across national boundaries) and other processing of such data. We typically collect and store IP addresses and other device identifiers (such as unique cookie identifiers and mobile application identifiers), which are or may be considered personal data or personal information in some jurisdictions or otherwise may be the subject of regulation. In connection with new products and services, we may also collect information that directly identifies individuals, such as email addresses and phone numbers.

The global regulatory landscape regarding the protection of personal information is evolving, and U.S. (state and federal) and foreign governments are considering enacting additional legislation related to privacy and data protection and we expect to see an increase in, or changes to, legislation and regulation in this area. For example, in the United States, a federal privacy law is the subject of active discussion and several bills have been introduced recently.

The State of California adopted two laws broadly regulating businesses’ processing of personal information, the California Consumer Privacy Act of 2018 (“CCPA”), and the California Privacy Rights Act (“CPRA”). The CCPA, which went into effect January 1, 2020, defines “personal information” broadly enough to include online identifiers provided by individuals’ devices, applications, and protocols (such as IP addresses, mobile application identifiers and unique cookie identifiers) and individuals’ location data. The CCPA establishes a new privacy framework for covered businesses by, among other requirements, establishing new data privacy rights for consumers in the State of California (including rights to deletion of and access to personal information), imposing special rules on the collection of consumer data from minors, creating new notice obligations and new limits on the “sale” of personal information (interpreted by many observers to include common advertising technology practices), and creating a new and potentially severe statutory damages framework for violations of the CCPA and for businesses that fail to implement reasonable security procedures and practices to prevent data breaches. The CCPA also offers the possibility for a consumer to recover statutory damages for certain violations and could open the door more broadly to additional risks of individual and class-action lawsuits even though the statute’s private right of action is limited in scope.

The CPRA, which takes effect in January 2023, expands upon the CCPA and imposes additional notice and opt out obligations on the digital advertising space, including an obligation to provide an opt-out for behavioral advertising.

In addition, two other states recently enacted comprehensive consumer privacy laws, Virginia and Colorado, and more states are expected to follow. Like the CPRA, the Virginia Consumer Data Protection Act (“VCDPA”) will go into effect on January 1, 2023, while the Colorado Privacy Act takes effect on July 1, 2023. The VCDPA and the Colorado Privacy Act both protect “personal data,” a concept defined broadly in each law. The laws grant individuals a range of privacy rights relating to their personal data, including the right to opt out of targeted advertising and certain profiling activities. The CPRA, VCDPA, and the Colorado Privacy Act will create additional compliance costs for us and our industry partners, though efforts taken toward compliance with other privacy laws will likely be applicable to many elements of the Virginia and Colorado statutes. Although we have attempted to mitigate certain risks posed by these laws through contractual and platform changes, we cannot predict with certainty the effect of these laws and their implementing regulations on our business.

Laws governing the processing of personal data in Europe (including the European Union and EEA, and the countries of Iceland, Liechtenstein, and Norway) also continue to impact us and continue to evolve. The General Data Protection Regulation (“GDPR”), which applies to us, came into effect on May 25, 2018. Like the laws passed in California, Virginia, and Colorado, the GDPR defines “personal data” broadly, and it enhances data protection obligations for controllers of such data and for service providers processing the data. It also provides certain rights, such as access and deletion, to the individuals about whom the personal data relates. The digital advertising industry has collaborated to create a user-facing framework for establishing and managing legal bases under the GDPR and other EU privacy laws including ePrivacy (discussed below). Although the framework is actively in use, we cannot predict its effectiveness over the long term. European regulators have questioned its viability and activists have filed complaints with regulators of alleged non-compliance by specific companies that employ the framework. Non-compliance with the GDPR can trigger steep fines of up to the greater of €20 million or 4% of total worldwide annual revenue. Relatedly, following the United Kingdom’s withdrawal from the EEA and the European Union, and the expiry of the transition period, we have to comply with both the GDPR and the United Kingdom Data Protection Act 2018, the latter regime having the ability to separately fine up to the greater of £17.5 million or 4% of global turnover. Continuing to maintain compliance with the requirements of the GDPR and the United Kingdom Data Protection Act 2018, including monitoring and adjusting to rulings and interpretations that affect our approach to compliance, requires significant time, resources and expense, as will the effort to monitor whether additional changes to our business practices and our backend configuration are needed, all of which may increase operating costs, or limit our ability to operate or expand our business.

30

Changes in data residency and cross-border transfer restrictions also impact our operations. For the transfer of personal data from the EU to the United States, like many U.S. and European companies, we have relied upon, and were certified under the EU-U.S. and Swiss-U.S. Privacy Shield Frameworks. The Privacy Shield Framework, however, was struck down in July 2020 by the EU Court of Justice (“Schrems II”) as an adequate mechanism by which EU companies may pass personal data to the United States, and other EU mechanisms for adequate data transfer, such as the standard contractual clauses, were questioned by the Court of Justice and whether and how standard contractual clauses can be used to transfer personal data to the United States is in question. In June 2021, the European Commission published revised standard contractual clauses, and shortly thereafter the European Data Protection Board promulgated guidance on implementation of the new clauses. Even with the additional clarity provided by these much-anticipated developments, the validity of the standard contractual clauses as a transfer mechanism remains uncertain. The concerns raised by the court in Schrems II relating to the perceived risks of transferring personal data to the United States, and the ability of the standard contractual clauses to address those risks, persist under the new standard contractual clauses framework. If all or some jurisdictions within the EU or the United Kingdom, determine that the new standard contractual clauses also cannot be used to transfer personal data to the United States, we could be left with no reasonable option for the lawful cross-border transfer of personal data. If left with no reasonable option for the lawful cross-border transfer of personal data, and if we nonetheless continue to transfer personal data from the EU to the United States, that could lead to governmental enforcement actions, litigation, fines and penalties or adverse publicity, which could have an adverse effect on our reputation and business or cause us to need to establish systems to maintain certain data in the EU, which may involve substantial expense and cause us to divert resources from other aspects of our operations, all of which may adversely affect our business. Other jurisdictions have adopted or are considering cross-border or data residency restrictions, which could reduce the amount of data we can collect or process and, as a result, significantly impact our business. It remains unclear how the withdrawal of the United Kingdom (“U.K.”) from the European Union, referred to as Brexit, will affect transborder data flows, regulators’ jurisdiction over our business, and other matters related to how we do business and how we comply with applicable data protection laws. Accordingly, we cannot predict the additional expense, impact on revenue, or other business impact that may stem from Brexit. We anticipate guidance from the U.K. in the coming months that will establish whether the EU’s new standard contractual clauses may be used for transfers from the U.K. to the United States.

Regulatory investigations and enforcement actions could also impact us. In the United States, the Federal Trade Commission (“FTC”) uses its enforcement powers under Section 5 of the Federal Trade Commission Act (which prohibits “unfair” and “deceptive” trade practices) to investigate companies engaging in online tracking. Other companies in the advertising technology space have been subject to government investigation by regulatory bodies; advocacy organizations have also filed complaints with data protection authorities against advertising technology companies, arguing that certain of these companies’ practices do not comply with the GDPR. We cannot avoid the possibility that one of these investigations or enforcement actions will require us to alter our practices. Further, our legal risk depends in part on our clients’ or other third parties’ adherence to privacy laws and regulations and their use of our services in ways consistent with end user expectations. We rely on representations made to us by clients that they will comply with all applicable laws, including all relevant privacy and data protection regulations. Although we make reasonable efforts to enforce such representations and contractual requirements, we do not fully audit our clients’ compliance with our recommended disclosures or their adherence to privacy laws and regulations. If our clients fail to adhere to our expectations or contracts in this regard, we and our clients could be subject to adverse publicity, damages, and related possible investigation or other regulatory activity.

Adapting our business to privacy laws enacted at the state level and their implementing regulations and to the enhanced and evolving privacy obligations in the EU and elsewhere could continue to involve substantial expense and may cause us to divert resources from other aspects of our operations, all of which may adversely affect our business. Additionally, as the advertising industry evolves, and new ways of collecting, combining and using data are created, governments may enact legislation in response to technological advancements and changes that could result in our having to re-design features or functions of our platform, therefore incurring unexpected compliance costs. Further, adaptation of the digital advertising marketplace requires increasingly significant collaboration between participants in the market, such as publishers and advertisers. Failure of the industry to adapt to changes required for operating under laws existing and future privacy laws and user response to such changes could negatively impact inventory, data, and demand. We cannot control or predict the pace or effectiveness of such adaptation, and we cannot currently predict the impact such changes may have on our business.

In addition to laws regulating the processing of personal information, we are also subject to regulation with respect to political advertising activities, which are governed by various federal and state laws in the U.S., and national and provincial laws worldwide. Online political advertising laws are rapidly evolving, and in certain jurisdictions have varying transparency and disclosure requirements. We saw publishers impose varying prohibitions and restrictions on the types of political advertising and breadth of targeted advertising allowed on their platforms with respect to advertisements for the 2020 U.S. presidential election in response to political advertising scandals, such as the scandal involving Cambridge Analytica. The lack of uniformity and increasing requirements on transparency and disclosure could adversely impact the inventory made available for political advertising and the demand for such inventory on our platform, and otherwise increase our operating and compliance costs. Concerns about political advertising or other advertising in areas deemed sensitive, whether or not valid and whether or not driven by applicable laws and regulations, industry standards, client or inventory provider expectations, or public perception, may harm our reputation, result in loss of goodwill, and inhibit use of our platform by current and future clients.

31

These laws and other obligations may be interpreted and applied in a manner that is inconsistent with our existing data management practices or the features of our platform. If so, in addition to the possibility of fines, lawsuits and other claims, we could be required to fundamentally change our business activities and practices or modify our products, which could have an adverse effect on our business. We may be unable to make such changes and modifications in a commercially reasonable manner or at all, and our ability to develop new products and features could be limited. All of this could impair our or our clients’ ability to collect, use, or disclose information relating to consumers, which could decrease demand for our platform, increase our costs, and impair our ability to maintain and grow our client base and increase our revenue.

Commitments to advertising technology industry self-regulation may subject us to investigation by government or self-regulatory bodies, government or private litigation, and operational costs or harm to reputation or brand.

In addition to our legal obligations, we have committed to comply, and generally require our clients and partners to comply, with applicable self-regulatory principles, such as the Network Advertising Initiative’s Code of Conduct and the Digital Advertising Alliance’s Self-Regulatory Principles for Online Behavioral Advertising in the U.S., and similar self-regulatory principles in Europe and Canada adopted by the local Digital Advertising Alliance. Trade associations and industry self-regulatory groups have also promulgated best practices and other industry standards relating to targeted advertising. Our efforts to comply with these self-regulatory principles include offering Internet users notice and choice when advertising is served to them based, in part, on their interests. If we or our clients or partners make mistakes in the implementation of these principles, or if self-regulatory bodies expand these guidelines or government authorities issue different guidelines regarding targeted advertising, or opt out mechanisms fail to work as designed, or if Internet users misunderstand our technology or our commitments with respect to these principles, we may, as a result, be subject to negative publicity, government investigation, government or private litigation, or investigation by self-regulatory bodies or other accountability groups. Any such action against us, or investigations, even if meritless, could be costly and time consuming, require us to change our business practices, cause us to divert management’s attention and our resources, and be damaging to our brand, reputation, and business. In addition, privacy advocates and industry groups may propose new and different self-regulatory standards that either legally or contractually apply to us. We cannot yet determine the impact such future standards may have on our business.

Third parties control our access to unique identifiers, and if the use of “third-party cookies” or other technology to uniquely identify devices is rejected by Internet users, restricted or otherwise subject to unfavorable regulation, blocked or limited by technical changes on end users’ devices and web browsers, or our and our clients’ ability to use data on our platform is otherwise restricted, our performance may decline and we may lose advertisers and revenue.

Our ability to successfully leverage user data and generate revenue from opportunities to serve advertisements could be impacted by restrictions imposed by third parties, including restrictions on our ability to use or read cookies, device identifiers, or other tracking features or our ability to use real-time bidding networks or other bidding networks. For example, if publishers or supply-side platforms decide to limit the data that we receive in order to comply (in their view) with the opt-out of sale provisions of the CCPA or a potential federal privacy law, or with opt-out of behavioral advertising provisions under the CPRA, VCDPA, or Colorado Privacy Act, then our service may prove to be less valuable to our clients and we may find it more difficult to generate revenue. That is, if third parties on which we rely for data or opportunities to serve advertisements impose limitations (for whatever reason) or are restricted by other ecosystem participants or applicable regulations, we may lose the ability to access data, bid on opportunities, or purchase digital ad space, which could have a substantial impact on our revenue.

Digital advertising mostly relies on the ability to uniquely identify devices across websites and applications, and to collect data about user interactions with those devices for purposes such as serving relevant ads and measuring the effectiveness of ads. Devices are identified through unique identifiers stored in cookies, provided by device operating systems for advertising purposes, or generated based on statistical algorithms applied to information about a device, such as the IP address and device type. We use device identifiers to record such information as when an Internet user views an ad, clicks on an ad, or visits one of our advertiser’s websites or applications. We use device identifiers to help us achieve our advertisers’ campaign goals, including to limit the instances that an Internet user sees the same advertisement, report information to our advertisers regarding the performance of their advertising campaigns, and detect and prevent malicious behavior and invalid traffic throughout our network of inventory. We also use data associated with device identifiers to help our clients decide whether to bid on, and how to price, an opportunity to place an advertisement in a specific location, at a given time, in front of a particular Internet user. Additionally, our clients rely on device identifiers to add information they have collected or acquired about users into our platform. Without such data, our clients may not have sufficient insight into an Internet user’s activity, which may compromise their and our ability to determine which inventory to purchase for a specific campaign and may undermine the effectiveness of our platform or our ability to improve our platform and remain competitive.

Today, digital advertising, including our platform, makes significant use of cookies to store device identifiers for the advertising activities described above. When we use cookies, they are generally considered third-party cookies, which are cookies owned and used by parties other than the owners of the website visited by the Internet user. The most commonly used Internet browsers—Chrome, Firefox, Internet Explorer and Safari—allow Internet users to modify their browser settings to prevent some or all cookies from being accepted by their browsers. Internet users can delete cookies from their computers at any time. Additionally, some browsers currently, or may in the future, block or limit some third-party cookies by default or may implement user control settings that algorithmically block or limit some cookies. Today, three major web browsers—Apple’s Safari, Mozilla’s Firefox, and Microsoft’s Edge—block third-party cookies by default. Google’s Chrome has introduced new controls over third-party cookies and announced plans to deprecate support for third-party cookies and user agent strings entirely by late 2023. Some Internet users also download free or paid ad blocking software that not only prevents third-party cookies from being stored on a user’s computer, but also blocks all interaction with a third-party ad server. In addition, Google has introduced ad blocking software in its Chrome web browser that will block certain ads based on quality standards established under a multi-stakeholder coalition. If such a feature inadvertently or mistakenly blocks ads that are not within the established blocking standards, or if such capabilities become widely adopted and the advertising technology industry does not collaboratively develop alternative technologies, our business could be harmed. The Interactive Advertising Bureau and Digital Advertising Alliance have also developed frameworks that allow users to opt out of the “sale” of their personal information under the CCPA in ways that stop or severely limit the ability to show targeted ads.

Advertising shown on mobile applications can also be affected by blocking or restricting use of mobile device identifiers. Data regarding interactions between users and devices are tracked mostly through stable, pseudonymous advertising identifiers that are built into the device operating system with privacy controls that allow users to express a preference with respect to data collection for advertising, including to disable the identifier. These identifiers and privacy controls are defined by the developers of the platforms through which the applications are accessed and could be changed by the platforms in a way that may negatively impact our business. For example, Apple has shifted to require user opt-in before permitting access to Apple’s unique identifier, or IDFA. This shift from enabling user opt-out to an opt-in requirement has had, and will likely continue to have, a substantial impact on the mobile advertising ecosystem and could adversely impact our growth in this channel.

In addition, in the EU, Directive 2002/58/EC (as amended by Directive 2009/136/EC), commonly referred to as the ePrivacy or Cookie Directive, directs EU member states to ensure that accessing information on an Internet user’s computer, such as through a cookie and other similar technologies, is allowed only if the Internet user has been informed about such access and given his or her consent. A ruling by the Court of Justice of the European Union clarified that such consent must be reflected by an affirmative act of the user, and European regulators are increasingly agitating for more robust forms of consent. These developments may result in decreased reliance on implied consent mechanisms that have been used to meet requirements of the Cookie Directive in some markets. A replacement for the Cookie Directive is currently under discussion by EU member states to complement and bring electronic communication services in line with the GDPR and force a harmonized approach across EU member states. Like the GDPR, the proposed ePrivacy Regulation has extra-territorial application as it applies to businesses established outside the EU who provide publicly available electronic communications services to, or gather data from the devices of, users in the EU. Though still subject to debate, the proposed ePrivacy Regulation may further raise the bar for the use of cookies and the fines and penalties for breach may be significant. We may be required to, or otherwise may determine that it is advisable to, make significant changes in our business operations and product and services to obtain user opt-in for cookies and use of cookie data, or develop or obtain additional tools and technologies to compensate for a lack of cookie data.

As the collection and use of data for digital advertising has received media attention over the past several years, some government regulators, such as the FTC, and privacy advocates have suggested creating a “Do Not Track” standard that would allow Internet users to express a preference, independent of cookie settings in their browser, not to have their online browsing activities tracked. “Do Not Track” has seen renewed emphasis from proponents of the CCPA, and the final regulations address browser-based or similar “do not sell” signals. California’s CPRA and the Colorado Privacy Act similarly contemplate the use of technical opt outs for the sale and sharing of personal information for advertising purposes as well as to opt out of the use of sensitive information for advertising purposes and allows for rulemaking to develop these technical signals. To the extent a “Do Not Track,” “Do Not Sell,” or similar control is adopted by many Internet users or if a “Do Not Track” standard is imposed by state, federal, or foreign legislation or is agreed upon by standard setting groups, we may have to change our business practices, our clients may reduce their use of our platform, and our business, financial condition, and results of operations could be adversely affected.

Increased transparency into the collection and use of data for digital advertising, introduced both through features in browsers and devices and regulatory requirements, such as the GDPR, state privacy laws, “Do Not Track,” and ePrivacy, as well as compliance with such requirements, may create operational burdens to implement and may lead more users to choose to block the collection and use of data about them. Adapting to these and similar changes has in the past and may in the future require significant time, resources and expense, which may increase our cost of operation or limit our ability to operate or expand our business.

Concerns regarding data privacy and security relating to our industry’s technology and practices, and perceived failure to comply with laws and industry self-regulation, could damage our reputation and deter current and potential clients from using our products and services.

Public perception regarding data protection and privacy are significant in the programmatic advertising buying industry. Concerns about industry practices with regard to the collection, use, and disclosure of personal information, whether or not valid and whether driven by applicable laws and regulations, industry standards, client or inventory provider expectations, or the broader public, may harm our reputation, result in loss of goodwill, and inhibit use of our platform by current and future clients. For example, perception that our practices involve an invasion of privacy, whether or not such practices are consistent with current or future laws, regulations, or industry practices, may subject us to public criticism, private class actions, reputational harm, or claims by regulators, which could disrupt our business and expose us to increased liability.

Our failure to meet standards and provide services that our advertisers and inventory suppliers trust, could harm our brand and reputation and those of our partners and negatively impact our business, financial condition and results of operations.

We do not provide or control the content of the advertisements that we serve or the content of the websites providing the inventory. Advertisers provide the advertising content and inventory suppliers provide the inventory. Both advertisers and inventory suppliers are concerned about being associated with content they consider inappropriate, competitive or inconsistent with their brands, or illegal, and they are hesitant to spend money or make inventory available, respectively, without some guarantee of brand security. Consequently, our reputation depends in part on providing services that our advertisers and inventory suppliers trust, and we have contractual obligations to meet content and inventory standards. We contractually prohibit the misuse of our platform by our clients and inventory suppliers. Additionally, we use our proprietary technology and third-party services to, and we participate in industry co-ops that work to, detect malware and other content issues as well as click fraud (whether by humans or software known as “bots”) and to block fraudulent inventory, including “tool bar” inventory, which is inventory that appears within an application and displaces any advertising that would otherwise be displayed on the website. Despite such efforts, our clients may inadvertently purchase inventory that proves to be unacceptable for their campaigns, in which case we may not be able to recoup the amounts paid to inventory suppliers. Preventing and combating fraud is an industry-wide issue that requires constant vigilance, and we cannot guarantee that we will be successful in our efforts. Our clients could intentionally run campaigns that do not meet the standards of our inventory suppliers or attempt to use illegal or unethical targeting practices or seek to display advertising in jurisdictions that do not permit such advertising or in which the regulatory environment is uncertain, in which case our supply of ad inventory from such suppliers could be jeopardized. Some of our competitors undertake human review of content, but because our platform is self-service, and because such means are cost-intensive, we do not utilize all means available to decrease these risks. We may provide access to inventory that is objectionable to our advertisers, serve advertising that contains malware, objectionable content, or is based on questionable targeting criteria to our inventory suppliers, or be unable to detect and prevent non-human traffic, any one of which could harm our or our clients’ brand and reputation, decrease their trust in our platform, and negatively impact our business, financial condition and results of operations.

If we fail to offer sufficient client training and support, our business and reputation would suffer.

Because we offer a self-service platform, client training and support is important for the successful marketing and continued use of our platform and for maintaining and increasing spend through our platform from existing and new clients. Providing this training and support requires that our platform operations personnel have specific domain knowledge and expertise along with the ability to train others, which makes it more difficult for us to hire qualified personnel and to scale up our support operations due to the extensive training required. The importance of high-quality client service will increase as we expand our business and pursue new clients. If we are not responsive and proactive regarding our clients’ advertising needs, or do not provide effective support for our clients’ advertising campaigns, our ability to retain our existing clients would suffer and our reputation with existing or potential clients would be harmed, which would negatively impact our business.

If the non-proprietary technology, software, products and services that we use are unavailable, have future terms we cannot agree to, or do not perform as we expect, our business, financial condition and results of operations could be harmed.

We depend on various technology, software, products and services from third parties or available as open source, including data centers and API technology, payment processing, payroll and other technology and professional services, some of which are critical to the features and functionality of our platform. For example, in order for clients to target ads in ways they desire and otherwise optimize and verify campaigns, our platform must have access to data regarding Internet user behavior and reports with demographic information regarding Internet users. Identifying, negotiating, complying with and integrating with third-party terms and technology are complex, costly and time-consuming matters. Failure by third-party providers to maintain, support or secure their technology either generally or for our accounts specifically, or downtime, errors or defects in their products or services, could adversely impact our platform, our administrative obligations or other areas of our business. Having to replace any third-party providers or their technology, products or services could result in outages or difficulties in our ability to provide our services. If we are unsuccessful in establishing or maintaining our relationships with our third-party providers or otherwise need to replace them, internal resources may need to be diverted and our business, financial condition and results of operations could be harmed.

34

Disruptions to service from our third-party data center hosting facilities and cloud computing and hosting providers could impair the delivery of our services and harm our business.

A significant portion of our business relies upon hardware and services that are hosted, managed and controlled by third-party co-location providers for our data centers, and we are dependent on these third parties to provide continuous power, cooling, Internet connectivity and physical and technological security for our servers. In the event that these third-party providers experience any interruption in operations or cease business for any reason, or if we are unable to agree on satisfactory terms for continued hosting relationships, we would be forced to enter into a relationship with other service providers or assume some hosting responsibilities ourselves. Even a disruption as brief as a few minutes could have a negative impact on marketplace activities and could result in a loss of revenue. These facilities may be located in areas prone to natural disasters and may experience catastrophic events such as earthquakes, fires, floods, power loss, telecommunications failures, public health crises and similar events. They may also be subject to break-ins, sabotage, intentional acts of vandalism, cyber-attacks and similar misconduct. Although we have made certain disaster recovery and business continuity arrangements, such events could cause damage to, or failure of, our systems generally, or those of the third-party cloud computing and hosting providers, which could result in disruptions to our service.

We face potential liability and harm to our business based on the human factor of inputting information into our platform.

Campaigns are set up using several variables available to our clients on our platform. While our platform includes several checks and balances, it is possible for human error to result in significant overspending. The system requires a daily cap at the ad group level. We also provide for the client to input daily and overall caps at the advertising inventory campaign level at their discretion. Additionally, we set a credit limit for each user so that they cannot spend beyond the level of credit risk we are willing to accept. Despite these protections, the ability for overspend exists. For example, campaigns which last for a period of time can be set to pace evenly or as quickly as possible. If a client with a high credit limit enters the wrong daily cap with a campaign set to a rapid pace, it is possible for a campaign to accidently go significantly over budget. While our client contracts state that clients are responsible for media purchased through our platform, we are ultimately responsible for paying the inventory providers, and we may be unable to collect from clients facing such issues, in which case our results of operations would be harmed.

We have international operations and plan to continue expanding abroad where we have more limited operating experience, which may subject us to additional cost and economic risks that can adversely affect our business, financial condition and results of operations.

Our international operations and expansion plans create challenges associated with supporting a rapidly growing business across a multitude of cultures, customs, monetary, legal and regulatory systems and commercial infrastructures. We have a limited operating history outside of the United States, and our ability to manage and expand our business and conduct our operations internationally requires considerable attention and resources.

We have personnel in countries within North America, Central America, Europe, Asia, and Australia, and we are continuing to expand our international operations. Some of the countries into which we are, or potentially may, expand score unfavorably on the Corruption Perceptions Index (“CPI”) of the Transparency International. Our teams in locations outside the United States are substantially smaller than some of our teams in the United States. To the extent we are unable to effectively engage with non-U.S. advertising agencies or international divisions of U.S. agencies due to our limited sales force capacity, or we are unable to secure quality non-U.S. ad inventory and data on reasonable terms due to our limited inventory and data team capacity, we may be unable to effectively grow in international markets.

Our international operations and expansion subject us to a variety of additional risks, including:

• risks related to local advertising markets, where adoption of programmatic ad buying may be slower than in the United States, advertising buyers and inventory and data providers may be less familiar with demand-side platforms and our brand, and business models may not support our value proposition;

• exposure to public health issues, and to travel restrictions and other measures undertaken by governments in response to such issues;

• risks related to compliance with local laws and regulations, including those relating to privacy, cybersecurity, data security, antitrust, data localization, anti-bribery, import and export controls, economic sanctions (including to existing and potential partners and clients), tax and withholding (including overlapping of different tax regimes), varied labor and employment laws (including those relating to termination of employees); corporate formation, partnership, restrictions on foreign ownership or investment, and other regulatory limitations or obligations on our operations (such as obtaining requisite licenses or other governmental requirements); and the increased administrative costs and risks associated with such compliance;

• operational and execution risk, and other challenges caused by distance, language and cultural differences, which may burden management, increase travel, infrastructure and legal compliance costs, and add complexity to our enforcement of advertising standards across languages and countries;

35

• geopolitical and social factors, such as concerns regarding negative, unstable or changing economic conditions in the countries and regions where we operate, global and regional recessions, political instability, and trade disputes;

• risks related to pricing structure, payment and currency, including aligning our pricing model and payment terms with local norms, higher levels of credit risk and payment fraud, difficulties in invoicing and collecting in foreign currencies and associated foreign currency exposure, and difficulties in repatriating or transferring funds from or converting currencies; and

• reduced protection for intellectual property rights in some countries and practical difficulties in enforcing contractual and intellectual property rights abroad.

We have a U.K. entity through which we have entered into international client and partner agreements, including with those in the EU, which are governed by English Law, and some of our clients and partners pay us in British Pounds and Euros. It is unclear what effects Brexit will have on the operational execution and enforcement of those agreements, transborder transactions generally, matters of taxation, transborder data flows, regulators’ jurisdiction over our business, and other matters related to how we do business in the U.K. and EU. Brexit may adversely affect economic conditions in the U.K., EU and elsewhere across the globe, and could contribute to volatility in foreign exchange markets with respect to the British Pound and Euro, which we may not be able to effectively manage, and our financial results could be adversely affected. Further, Brexit may add additional complexity to our European operations, which are headquartered in the U.K. Accordingly, we cannot predict the additional expense, impact on revenue, or other business impact that may stem from Brexit.

We may incur significant operating expenses as a result of our international operations and expansion, and we may not be successful. Our international business also subjects us to the impact of differing regulatory requirements, costs and difficulties in managing a distributed workforce, and potentially adverse tax consequences in the United States and abroad. If our international activities were found to be in violation of any existing or future international laws or regulations or if interpretations of those laws and regulations were to change, our business in those countries could be subject to fines and other financial penalties, have licenses revoked, or be forced to restructure operations or shut down entirely. In addition, advertising markets outside of the United States are not as developed as those within the United States, and we may be unable to grow our business sufficiently. Any failure to successfully manage the risks and challenges related to our international operations could adversely affect our business, financial condition and results of operations.

We have entered into, and may in the future enter into, credit facilities which may contain operating and financial covenants that restrict our business and financing activities.

We have entered into, and may in the future enter into, credit facilities which contain restrictions that limit our flexibility in operating our business. Our credit facility contains, and any future credit facility may contain, various covenants that limit our ability to engage in specified types of transactions. Subject to exceptions, these covenants limit our ability to, among other things:

• sell assets or make changes to the nature of our business;

• engage in mergers or acquisitions;

• incur, assume or permit additional indebtedness and guarantees;

• make restricted payments, including paying dividends on, repurchasing, redeeming or making distributions with respect to our capital stock;

• make specified investments;

• engage in transactions with our affiliates; and

• make payments in respect of subordinated debt.

Our obligations under our credit facility are collateralized by a pledge of substantially all of our assets, including accounts receivable, deposit accounts, intellectual property, and investment property and equipment. The covenants in our credit facility may limit our ability to take actions and, in the event that we breach one or more covenants, our lenders may choose to declare an event of default and require that we immediately repay all amounts outstanding, terminate the commitment to extend further credit and foreclose on the collateral granted to them to collateralize such indebtedness, which includes our intellectual property. In addition, if we fail to meet the required covenants, we will not have access to further draw-downs under our credit facility.

36

Our future success depends on the continuing efforts of our key employees, including Jeff T. Green and David R. Pickles, and our ability to attract, hire, retain and motivate highly skilled employees in the future.

Our future success depends on the continuing efforts of our executive officers and other key employees, including our two founders, Jeff T. Green, our Chief Executive Officer, and David R. Pickles, our Chief Technology Officer. We rely on the leadership, knowledge, and experience that our executive officers provide. They foster our corporate culture, which has been instrumental to our ability to attract and retain new talent. We also rely on our ability to hire and retain qualified and motivated employees, particularly those employees in our product development, support, and sales teams that attract and keep key clients.

The market for talent in many of our areas of operations, including California and New York, is intensely competitive, as technology companies like ours compete to attract the best talent. As a business-to-business company, we do not have the same level of name recognition among potential recruits as business-to-consumer companies. Additionally, we have less experience with recruiting and less name recognition in geographies outside of the United States and may face additional challenges in attracting and retaining international employees. As a result, we may incur significant costs to attract and retain employees, including significant expenditures related to salaries and benefits and compensation expenses related to equity awards, and we may lose new employees to our competitors or other companies before we realize the benefit of our investment in recruiting and training them. New employees often require significant training and, in many cases, take significant time before they achieve full productivity. Our account managers, for instance, need to be trained quickly on the features of our platform since failure to offer high-quality support may adversely affect our relationships with our clients.

Employee turnover, including changes in our management team, could disrupt our business. None of our founders or other key employees have an employment agreement for a specific term, and all of our employees may terminate his or her employment with us at any time. The loss of one or more of our executive officers, especially our two founders, or our inability to attract and retain highly skilled employees could have an adverse effect on our business, financial condition and results of operations.

If we do not effectively grow and train our sales and client service teams, we may be unable to add new clients or increase sales to our existing clients and our business will be adversely affected.

We are substantially dependent on our sales and client service teams to obtain new clients and to increase spend by our existing clients. We believe that there is significant competition for sales personnel with the skills and technical knowledge that we require. Our ability to achieve revenue growth will depend, in large part, on our success in recruiting, training, integrating and retaining sufficient numbers of sales personnel to support our growth. Due to the complexity of our platform, new hires require significant training and it may take significant time before they achieve full productivity. Our recent and planned hires may not become productive as quickly as we expect, and we may be unable to hire or retain sufficient numbers of qualified individuals in the markets where we do business or plan to do business. If we are unable to hire and train sufficient numbers of effective sales personnel, or the sales personnel are not successful in obtaining new clients or increasing our existing clients’ spend with us, our business will be adversely affected.

Our corporate culture has contributed to our success, and if we are unable to maintain it as we grow, our business, financial condition, and results of operations could be harmed.

We have experienced and may continue to experience rapid expansion of our employee ranks. We believe our corporate culture has been a key element of our success. However, as our organization grows, it may be difficult to maintain our culture, which could reduce our ability to innovate and operate effectively. The failure to maintain the key aspects of our culture as our organization grows could result in decreased employee satisfaction, increased difficulty in attracting top talent, increased turnover and could compromise the quality of our client service, all of which are important to our success and to the effective execution of our business strategy. In the event we are unable to maintain our corporate culture as we grow to scale, our business, financial condition and results of operations could be harmed.

37

Our proprietary rights may be difficult to enforce, which could enable others to copy or use aspects of our technology without compensating us, thereby eroding our competitive advantages and harming our business.

We rely upon a combination of trade secrets, third-party confidentiality and non-disclosure agreements, additional contractual restrictions on disclosure and use, and trademark, copyright, patent and other intellectual property laws to establish and protect our proprietary rights. These laws, procedures and restrictions provide only limited protection. We currently have “theTradeDesk” and variants and other marks registered as trademarks or pending registrations in the United States and certain foreign countries. We also rely on copyright laws to protect computer programs related to our platform and our proprietary technologies, although to date we have not registered for statutory copyright protection. We have registered numerous Internet domain names in the United States and certain foreign countries related to our business. We endeavor to enter into agreements with our employees and contractors in order to limit access to and disclosure of our proprietary information, as well as to clarify rights to intellectual property associated with our business. Protecting our intellectual property is a challenge, especially after our employees or our contractors end their relationship with us, and, in some cases, decide to work for our competitors. Our contracts with our employees and contractors that relate to intellectual property issues generally restrict the use of our confidential information solely in connection with our services, and strictly prohibit reverse engineering. However, reverse engineering our software or the theft or misuse of our proprietary information could occur by employees or other third parties who have access to our technology. Enforceability of the non-compete agreements that we have in place is not guaranteed, and contractual restrictions could be breached without discovery or adequate remedies. Historically, we have prioritized keeping our technology architecture, trade secrets, and engineering roadmap private, and as a general matter, have not patented our proprietary technology. As a result, we cannot look to patent enforcement rights to protect much of our proprietary technology. Furthermore, our patent strategy is still in its early stages. We may not be able to obtain any further patents, and our pending applications may not result in the issuance of patents. Any issued patents may be challenged, invalidated or circumvented, and any rights granted under these patents may not actually provide adequate defensive protection or competitive advantages to us. Additionally, the process of obtaining patent protection is expensive and time-consuming, and we may not be able to prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner.

Policing unauthorized use of our technology is difficult. In addition, the laws of some foreign countries may not be as protective of intellectual property rights as those of the United States, and mechanisms for enforcement of our proprietary rights in such countries may be inadequate. If we are unable to protect our proprietary rights (including in particular, the proprietary aspects of our platform) we may find ourselves at a competitive disadvantage to others who have not incurred the same level of expense, time and effort to create and protect their intellectual property.

We may be sued by third parties for alleged infringement of their proprietary rights, which would result in additional expense and potential damages.

There is significant patent and other intellectual property development activity in the digital advertising industry. Third-party intellectual property rights may cover significant aspects of our technologies or business methods or block us from expanding our offerings. Our success depends on the continual development of our platform. From time to time, we may receive claims from third parties that our platform and underlying technology infringe or violate such third parties’ intellectual property rights. To the extent we gain greater public recognition, we may face a higher risk of being the subject of intellectual property claims. The cost of defending against such claims, whether or not the claims have merit, is significant, regardless of whether we are successful in our defense, and could divert the attention of management, technical personnel and other employees from our business operations. Litigation regarding intellectual property rights is inherently uncertain due to the complex issues involved, and we may not be successful in defending ourselves in such matters. Additionally, we have obligations to indemnify our clients or inventory and data suppliers in connection with certain intellectual property claims. If we are found to infringe these rights, we could potentially be required to cease utilizing portions of our platform. We may also be required to develop alternative non-infringing technology, which could require significant time and expense. Additionally, we could be required to pay royalty payments, either as a one-time fee or ongoing, as well as damages for past use that was deemed to be infringing. If we cannot license or develop technology for any allegedly infringing aspect of our business, we would be forced to limit our service and may be unable to compete effectively. Any of these results could harm our business.

We face potential liability and harm to our business based on the nature of our business and the content on our platform.

Advertising often results in litigation relating to misleading or deceptive claims, copyright or trademark infringement, public performance royalties or other claims based on the nature and content of advertising that is distributed through our platform. Though we contractually require clients to generally represent to us that their advertisements comply with our ad standards and our inventory providers’ ad standards and that they have the rights necessary to serve advertisements through our platform, we do not independently verify whether we are permitted to deliver, or review the content of, such advertisements. If any of these representations are untrue, we may be exposed to potential liability and our reputation may be damaged. While our clients are typically obligated to indemnify us, such indemnification may not fully cover us, or we may not be able to collect. In addition to settlement costs, we may be responsible for our own litigation costs, which can be expensive.

38

We are subject to anti-bribery, anti-corruption and similar laws and non-compliance with such laws can subject us to criminal penalties or significant fines and harm our business and reputation.

We are subject to anti-bribery and similar laws, such as the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the USA PATRIOT Act, U.S. Travel Act, the U.K. Bribery Act 2010 and Proceeds of Crime Act 2002, and possibly other anti-corruption, anti-bribery and anti-money laundering laws in countries in which we conduct business. Anti-corruption laws have been enforced with great rigor in recent years and are interpreted broadly. Such laws prohibit companies and their employees and their agents from making or offering improper payments or other benefits to government officials and others in the private sector. As we increase our international sales and business, particularly in countries with a low score on the CPI by Transparency International, and increase our use of third parties such as sales agents, distributors, resellers or consultants, our risks under these laws will increase. We adopt appropriate policies and procedures and conduct training, but cannot guarantee that improprieties will not occur. Noncompliance with these laws could subject us to investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting with specified persons, the loss of export privileges, reputational harm, adverse media coverage, and other collateral consequences. Any investigations, actions and/or sanctions could have a material negative impact on our business, financial condition and results of operations.

We are subject to governmental economic sanctions requirements and export and import controls that could impair our ability to compete in international markets or subject us to liability if we are not in compliance with applicable laws.

As a U.S. company, we are subject to U.S. export control and economic sanctions laws and regulations, and we are required to export our technology and services in compliance with those laws and regulations, including the U.S. Export Administration Regulations and economic embargo and trade sanctions programs administered by the Treasury Department’s Office of Foreign Assets Control. U.S. economic sanctions and export control laws and regulations prohibit the shipment of specified products and services to countries, governments and persons targeted by U.S. sanctions. While we take precautions to prevent doing any business, directly or indirectly, with countries, governments and persons targeted by U.S. sanctions and to ensure that our technology and services are not exported or used by countries, governments and persons targeted by U.S. sanctions, such measures may be circumvented. There can be no assurance that we will be in compliance with U.S. export control or economic sanctions laws and regulations in the future. Any such violation could result in significant criminal or civil fines, penalties or other sanctions and repercussions, including reputational harm that could materially adversely impact our business.

Furthermore, if we export our technology, the exports may require authorizations, including a license, a license exception or other appropriate government authorization. Complying with export control and sanctions regulations may be time-consuming and may result in the delay or loss of opportunities.

In addition, various countries regulate the import of encryption technology, including the imposition of import permitting and licensing requirements, and have enacted laws that could limit our ability to offer our platform or could limit our clients’ ability to use our platform in those countries. Changes in our platform or future changes in export and import regulations may create delays in the introduction of our platform in international markets or prevent our clients with international operations from deploying our platform globally. Any change in export or import regulations, economic sanctions or related legislation, or change in the countries, governments, persons, or technologies targeted by such regulations, could result in decreased use of our platform by, or in our decreased ability to export our technology and services to, existing or potential clients with international operations. Any decreased use of our platform or limitation on our ability to export our platform would likely adversely affect our business, financial condition and results of operations.

• departures of key employees; or

• an adverse impact on us from any of the other risks cited herein.

In addition, if the stock market for technology companies, or the stock market generally, experiences a loss of investor confidence, the trading price of our Class A common stock could decline for reasons unrelated to our business, financial condition, or results of operations. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. The trading price of our Class A common stock might also decline in reaction to events that affect other companies in our industry even if these events do not directly affect us. In the past, stockholders have filed securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our core business, and adversely affect our business.

Substantial future sales of shares of our common stock could cause the market price of our Class A common stock to decline.

The market price of our Class A common stock could decline as a result of substantial sales of our common stock, particularly sales by our directors, executive officers, and significant stockholders or the perception in the market that holders of a large number of shares intend to sell their shares.

Additionally, our directors, executive officers, employees and, in certain instances, service providers, hold shares of common stock subject to outstanding options, restricted stock awards and restricted stock units under our equity incentive plans. Those shares and the shares reserved for future issuance under our equity incentive plans are and will become eligible for sale in the public market, subject to certain legal and contractual limitations.

Certain holders of our common stock have rights, subject to some conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or our stockholders.

Insiders have substantial control over our company, including as a result of the dual class structure of our common stock, which could limit your ability to influence the outcome of key decisions, including a change of control.

Our Class B common stock has ten votes per share, and our Class A common stock has one vote per share. Because of the ten-to-one voting ratio between our Class B and Class A common stock, the holders of our Class B common stock collectively continue to control a majority of the combined voting power of our common stock and therefore are able to control all matters submitted to our stockholders for approval so long as the shares of Class B common stock represent at least 9.1% of all outstanding shares of our Class A and Class B common stock in the aggregate. Our 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. As of September 30, 2021, stockholders who held shares of Class B common stock, including our executive officers, employees, and directors and their affiliates, together held approximately 51% of the voting power of our outstanding capital stock. This concentrated control limits or precludes your ability to influence corporate matters, as the holders of Class B common stock are able to influence or control matters requiring approval by our stockholders, including the election of the directors, excluding the director we plan to designate as a Class A director, and the approval of mergers, acquisitions or other extraordinary transactions. Their interests may differ from yours and they may vote in a manner that is adverse to your interests. This ownership concentration may deter, delay or prevent a change of control of our company, deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company and may ultimately affect the market price of our common stock. Furthermore, in connection with the amendments to our certificate of incorporation and related matters voted on at the Special Meeting of Stockholders held on December 22, 2020, we have become subject to legal proceedings and could become involved in additional litigation, including securities class action claims and/or derivative litigation. Any such legal proceedings, regardless of outcome or merit, may divert management’s time and attention and may result in the incurrence of significant expense, including legal fees. For additional information regarding the pending legal proceeding, refer to Legal Proceedings.

40

Transfers by holders of Class B common stock will generally result in those shares converting to Class A common stock, subject to limited exceptions, such as transfers effected for estate planning or charitable purposes. However, until the conversion of all outstanding shares of Class B common stock, the conversion of Class B common stock to Class A common stock will have the effect, over time, of increasing the voting power of those holders of Class B common stock who retain their shares in the long term.

Our charter documents and Delaware law could discourage takeover attempts and other corporate governance changes.

Our certificate of incorporation and bylaws contain provisions that could delay or prevent a change in control of our company. These provisions could also make it difficult for stockholders to elect directors that are not nominated by the current members of our board of directors or take other corporate actions, including effecting changes in our management. These provisions include the following provisions:

• permit the board of directors to establish the number of directors and fill any vacancies and newly created directorships;

• provide that our board of directors will be classified into three classes with staggered, three-year terms and that directors may only be removed for cause;

• require super-majority voting to amend certain provisions in our certificate of incorporation and bylaws;

• authorize the issuance of “blank check” preferred stock that our board of directors could use to implement a stockholder rights plan;

• specify that special meetings of our stockholders can be called only by our board of directors, the chairman of our board of directors, our chief executive officer, or a stockholder that has held at least 20% of our outstanding shares of common stock continuously for one year;

• prohibit stockholder action by written consent until the outstanding shares of Class B common stock represent less than 50% of our outstanding voting power, which until such time requires all stockholder actions to be taken at a meeting of our stockholders;

• provide that the board of directors is expressly authorized to make, alter or repeal our bylaws;

• provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even though less than a quorum;

• prohibit cumulative voting in the election of directors;

• restrict the forum for certain litigation against us to Delaware;

• permit our board of directors to alter our bylaws without obtaining stockholder approval;

• reflect the dual class structure of our common stock, as discussed above; and

• establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at annual stockholder meetings.

In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a period of time.

Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between us and our stockholders, which limits our stockholders’ ability to choose other forums for disputes with us or our directors, officers or employees.

Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the sole and exclusive forum for: (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a claim of breach of a fiduciary duty by any of our directors, officers, employees, or our stockholders owed to us or our stockholders; (3) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or our bylaws, or as to which the Delaware General Corporation Law confers jurisdiction on the Court of Chancery of the State of Delaware; or (4) any action asserting a claim governed by the internal affairs doctrine. This choice of forum provision may limit a stockholder’s ability to bring a claim in other judicial forums for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers and other employees in jurisdictions other than Delaware. Alternatively, if a court were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could have a material adverse effect our business, financial condition, or results of operations.

41

General Risk Factors

If we fail to maintain an effective system of internal control over financial reporting in the future, we may not be able to accurately or timely report our financial condition or results of operations. If our internal control over financial reporting is not effective, it may adversely affect investor confidence in us and the price of our common stock.

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal control. Section 404 of the Sarbanes-Oxley Act of 2002, as amended (the “Sarbanes-Oxley Act”) requires that we evaluate and determine the effectiveness of our internal control over financial reporting and provide a management report on internal control over financial reporting.

Our platform system applications are complex, multi-faceted and include applications that are highly customized in order to serve and support our clients, advertising inventory and data suppliers, as well as support our financial reporting obligations. We regularly make improvements to our platform to maintain and enhance our competitive position. In the future, we may implement new offerings and engage in business transactions, such as acquisitions, reorganizations or implementation of new information systems. These factors require us to develop and maintain our internal controls, processes and reporting systems, and we expect to incur ongoing costs in this effort. We may not be successful in developing and maintaining effective internal controls, and any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or improvement, could harm our operating results or cause us to fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods.

If we identify material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective. If we are unable to assert that our internal control over financial reporting is effective, if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, or if we are unable to comply with the requirements of the Sarbanes-Oxley Act in a timely manner, then, we may be late with the filing of our periodic reports, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our common stock could be negatively affected. Such failures could also subject us to investigations by Nasdaq, the stock exchange on which our securities are listed, the SEC or other regulatory authorities, and to litigation from stockholders, which could harm our reputation, financial condition or divert financial and management resources from our core business.

The requirements of being a public company may strain our resources, divert our management’s attention and affect our ability to attract and retain qualified board members.

As a public company, we are subject to the reporting requirements of the Exchange Act, and are required to comply with the applicable requirements of the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of Nasdaq, and other applicable securities rules and regulations. Compliance with these rules and regulations increases our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and increase demand on our systems and resources. Among other things, the Exchange Act requires that we file annual, quarterly and current reports with respect to our business and results of operations and maintain effective disclosure controls and procedures and internal controls over financial reporting. Significant resources and management oversight are required to maintain and, if required, improve our disclosure controls and procedures and internal controls over financial reporting to meet this standard. As a result, management’s attention may be diverted from other business concerns, which could harm our business and results of operations.

Exposure to foreign currency exchange rate fluctuations could negatively impact our results of operations.

While the majority of the transactions through our platform are denominated in U.S. Dollars, we have transacted in foreign currencies, both for inventory and for payments by clients from use of our platform. We also have expenses denominated in currencies other than the U.S. Dollar. Given our anticipated international growth, we expect the number of transactions in a variety of foreign currencies to continue to grow in the future. While we generally require a fee from our clients that pay in non-U.S. currency, this fee may not always cover foreign currency exchange rate fluctuations. Although we currently have a program to hedge exposure to foreign currency fluctuations, the use of hedging instruments may not be available for all currencies or may not always offset losses resulting from foreign currency exchange rate fluctuations. Moreover, the use of hedging instruments can itself result in losses if we are unable to structure effective hedges with such instruments.

42

Future acquisitions, strategic investments or alliances could disrupt our business and harm our business, financial condition and results of operations.

We explore, on an ongoing basis, potential acquisitions of companies or technologies, strategic investments, or alliances to strengthen our business, however, we have limited experience in acquiring and integrating businesses, products and technologies. Even if we identify an appropriate acquisition candidate, we may not be successful in negotiating the terms or financing of the acquisition, and our due diligence may fail to identify all of the problems, liabilities or other shortcomings or challenges of an acquired business, product or technology, including issues related to intellectual property, product quality or architecture, regulatory compliance practices, revenue recognition or other accounting practices or employee or client issues. Acquisitions involve numerous risks, any of which could harm our business, including:

• regulatory hurdles;

• anticipated benefits may not materialize;

• diversion of management time and focus from operating our business to addressing acquisition integration challenges;

• retention of employees from the acquired company;

• cultural challenges associated with integrating employees from the acquired company into our organization;

• integration of the acquired company’s products and technology;

• integration of the acquired company’s accounting, management information, human resources and other administrative systems;

• the need to implement or improve controls, procedures and policies at a business that, prior to the acquisition, may have lacked effective controls, procedures and policies;

• coordination of product development and sales and marketing functions;

• liability for activities of the acquired company before the acquisition, including relating to privacy and data security, patent and trademark infringement claims, violations of laws, commercial disputes, tax liabilities and other known and unknown liabilities; and

• litigation or other claims in connection with the acquisition, including claims from terminated employees, users, former stockholders or other third parties.

Failure to appropriately mitigate these risks or other issues related to such acquisitions and strategic investments could result in reducing or completely eliminating any anticipated benefits of transactions, and harm our business generally. Future acquisitions could also result in dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities, amortization expenses or the impairment of goodwill, any of which could harm our business, financial condition and results of operations.

We may not be able to secure additional financing on favorable terms, or at all, to meet our future capital needs, which may in turn impair our growth.

We intend to continue to grow our business, which will require additional capital to develop new features or enhance our platform, improve our operating infrastructure, finance working capital requirements, or acquire complementary businesses and technologies. We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under our existing credit facility in an amount sufficient to fund our working capital needs. Accordingly, we may need to engage in additional equity or debt financings to secure additional capital. We cannot assure you that we would be able to locate additional financing on commercially reasonable terms or at all. Any debt financing that we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities. If our cash flows and credit facility borrowings are insufficient to fund our working capital requirements, we may not be able to grow at the rate we currently expect or at all. In addition, in the absence of sufficient cash flows from operations, we might be unable to meet our obligations under our credit facility, and we may therefore be at risk of default thereunder. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. If we are unable to secure additional funding on favorable terms, or at all, when we require it, our ability to continue to grow our business to react to market conditions could be impaired and our business may be harmed.

43

The phase out of the London Interbank Offered Rate (LIBOR), or the replacement of LIBOR with a different reference rate, may adversely affect interest rates.

Our revolving credit facility has interest rates tied to LIBOR. On November 30, 2020, the ICE Benchmark Administration (the Financial Conduct Authority-regulated and authorized administrator of LIBOR) announced that it would cease the publication of the one week and two-month USD LIBOR settings at the end of 2021 and phase out the remaining USD LIBOR settings by the end of 2023. Although many of our LIBOR-based obligations provide for alternative methods of calculating the interest rate payable if LIBOR is not reported, the extent and manner of any future changes with respect to methods of calculating LIBOR or replacing LIBOR with another benchmark are unknown and impossible to predict at this time and, as such, may result in interest rates that are materially higher than current interest rates. This could materially and adversely affect our results of operations, cash flows and liquidity.

Our tax liabilities may be greater than anticipated.

The U.S. and non-U.S. tax laws applicable to our business activities are subject to interpretation and are changing. We are subject to audit by the Internal Revenue Service and by taxing authorities of the state, local and foreign jurisdictions in which we operate. Our tax obligations are based in part on our corporate operating structure, including the manner in which we develop, value, use and hold our intellectual property, the jurisdictions in which we operate, how tax authorities assess revenue-based taxes such as sales and use taxes, the scope of our international operations and the value we ascribe to our intercompany transactions. Taxing authorities may challenge, and have challenged, our tax positions and methodologies for valuing developed technology or intercompany arrangements, positions regarding the collection of sales and use taxes, and the jurisdictions in which we are subject to taxes, which could expose us to additional taxes. Any adverse outcomes of such challenges to our tax positions could result in additional taxes for prior periods, interest and penalties, as well as higher future taxes. In addition, our future tax expense could increase as a result of changes in tax laws, regulations or accounting principles, or as a result of earning income in jurisdictions that have higher tax rates. For example, the European Commission has proposed, and various jurisdictions, including a number of states in the United States, are considering enacting or have enacted laws that impose separate taxes on specified digital services, which may increase our tax obligations in such jurisdictions. Any increase in our tax expense could have a negative effect on our financial condition and results of operations. Moreover, the determination of our provision for income taxes and other tax liabilities requires significant estimates and judgment by management, and the tax treatment of certain transactions is uncertain. Any changes, ambiguity, or uncertainty in taxing jurisdictions’ administrative interpretations, decisions, policies and positions, including, the position of taxing authorities with respect to revenue generated by reference to certain digital services, could also materially impact our income tax liabilities. Although we believe we will make reasonable estimates and judgments, the ultimate outcome of any particular issue may differ from the amounts previously recorded in our financial statements and any such occurrence could materially affect our financial condition and results of operations.

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

During the three months ended September 30, 2021, we issued a total of 167,172 shares of our Class A common stock in connection with the acquisition of a technology company, which shares were issued in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended.

Basis of Presentation and Summary of Significant Accounting Policies

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

The accompanying condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and are unaudited. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. The condensed consolidated balance sheet as of December 31, 2020 was derived from audited financial statements but does not include all disclosures required by GAAP. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in its Annual Report on Form 10-K for the year ended December 31, 2020.

There have been no material changes to the Company’s accounting policies from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2020, and these unaudited interim condensed consolidated financial statements have been prepared on a basis consistent with that used to prepare the Company’s audited annual consolidated financial statements for the year ended December 31, 2020, and include, in the opinion of management, all adjustments, consisting of normal recurring items, necessary for the fair statement of the condensed consolidated financial statements.

The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results expected for the full year ending December 31, 2021.

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 condensed 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from these estimates.

As of September 30, 2021, the impact of the Coronavirus pandemic (“COVID-19”) on the Company’s business continued to evolve. As a result, many of the Company’s estimates and assumptions, including the allowance for credit losses, consider macro-economic 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.

For the three and nine months ended September 30, 2021, the Company’s assessment of credit losses considered business and market disruptions caused by COVID-19 and estimates of defaults by industry. The Company reviews the allowance for credit losses and financial implications of COVID-19 on expected 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.

Business Combinations

The results of a business combination are included in the Company’s condensed 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 $17.8 million, subject to purchase price adjustments. The purchase consideration was primarily attributable to non-deductible goodwill of $11.4 million, with the remainder allocated to acquired technology and other assets.

Recent Accounting Pronouncements 

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate or by another reference rate expected to be discontinued. The amendments are effective for all entities through December 31, 2022 and can be adopted as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020. The adoption of the amendment did not have a material impact on the Company’s condensed consolidated financial statements.

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 $450.0 million revolving loan facility, with a $20.0 million sublimit for swingline borrowings and a $15.0 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 $300.0 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.

Loans under the credit facility bear 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 LIBOR rate, plus an applicable margin (“Base Rate Borrowings” and “LIBOR Rate Borrowings”). The 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 LIBOR rate for a one month interest period on such day plus 1%. The applicable margin is 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.

As of September 30, 2021, the Company did not have an outstanding debt balance under the credit facility. Availability under the credit facility was $443.9 million as of September 30, 2021, which is net of outstanding letters of credit of $6.1 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 September 30, 2021, the Company was in compliance with all covenants.

Income Taxes

Note 8—Income Taxes

In determining the interim income tax provision for the nine months ended September 30, 2021, the Company utilized the annual estimated effective tax rate applied to the actual year-to-date income and added the tax effects of any discrete items in the reporting period in which they occur. In determining the interim benefit from income taxes for the nine months ended September 30, 2020, the Company utilized the discrete effective tax rate method, as allowed by Accounting Standards Codification (“ASC”) 740-270-30-18, “Income Taxes – Interim Reporting”.

For the three months ended September 30, 2021 and 2020, the income tax provision included benefits associated with stock-based awards in the amounts of $21.9 million and $25.6 million, respectively. For the nine months ended September 30, 2021 and 2020, the provision for (benefit from) income taxes included benefits associated with stock-based awards in the amounts of $58.2 million and $98.7 million, respectively.

For the nine months ended September 30, 2021, and 2020, the Company’s effective tax rate differed from the United States federal statutory tax rate of 21% primarily due to the impact of tax benefits associated with stock-based awards, nondeductible stock-based compensation, state and foreign taxes, and research and development tax credits.

On June 10, 2021, the UK Finance Act 2021 was enacted, increasing the corporate tax rate from 19% to 25%. Accordingly, the Company increased its net UK deferred tax assets by $76.4 million, which was fully offset by a valuation allowance.

There were no material changes to the Company’s unrecognized tax benefits during the nine months ended September 30, 2021, and the Company does not expect to have any significant changes to unrecognized tax benefits through the end of the fiscal year.

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”). The Company generally bills clients for the gross amount of Supplier Features they purchase through its platform and the platform fees, net of allowances (“Gross Billings”). The Company’s accounts receivable are recorded at the amount of Gross Billings for the amounts it is responsible to collect, and accounts payable are 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.

Gross Billings, set forth as a percentage, based on the billing address of the clients or client affiliates, were as follows:

Commitments and Contingencies

Note 10— Commitments and Contingencies

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 its balance sheet, statement of income or statement of cash flows. Accordingly, no amounts for any obligation have been recorded at September 30, 2021.

Litigation

From time to time, the Company is subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings 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.

On June 28, 2021, a class action lawsuit was filed against the Company, the members of the Company’s board of directors, and one of the Company’s executive officers (collectively, the “Defendants”) in the Court of Chancery of the State of Delaware. The complaint alleges generally that the Defendants breached their fiduciary duties to the Company’s stockholders in connection with the negotiation and approval of the amendments to the Company’s certificate of incorporation and related matters voted on at the Special Meeting of Stockholders held on December 22, 2020 (the “Amendments”). Plaintiff seeks a court order rescinding the Amendments, as well as monetary damages. On August 27, 2021, the Defendants moved to dismiss the complaint. On October 8, 2021, the plaintiff filed an opposition to Defendants’ motion to dismiss the complaint. The Company believes that all of the claims asserted in the complaint are without merit and intends to defend against them vigorously. However, litigation is inherently uncertain and there can be no assurance regarding the likelihood that the Defendants’ defense of the action 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-based awards in the event of changes in control, as defined, and involuntary terminations.

Note 11— Subsequent Event 

On October 6, 2021, the Company granted a market-based performance award (the “Performance Option”) to the Company’s Chief Executive Officer (the “CEO”) 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, the CEO may purchase up to 16,000,000 shares of Class A common stock, to be earned in eight equal tranches, 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. The Performance Option has an exercise price of $68.29 per share and a grant-date fair value of approximately $819.0 million, which is expected to be expensed on a graded-vesting basis over a period of approximately five years but may be accelerated if the vesting criteria is met prior to the estimated performance period. Stock-based compensation expense for the Performance Option will be recorded as a component of general and administrative expense in the Company’s consolidated statement of operations beginning in the fourth quarter of 2021 and, assuming no acceleration of vesting, will be recognized over a weighted-average period of 2.9 years.

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates

The preparation of condensed 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 condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from these estimates.

As of September 30, 2021, the impact of the Coronavirus pandemic (“COVID-19”) on the Company’s business continued to evolve. As a result, many of the Company’s estimates and assumptions, including the allowance for credit losses, consider macro-economic 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.

For the three and nine months ended September 30, 2021, the Company’s assessment of credit losses considered business and market disruptions caused by COVID-19 and estimates of defaults by industry. The Company reviews the allowance for credit losses and financial implications of COVID-19 on expected 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.

Business Combinations

Business Combinations

The results of a business combination are included in the Company’s condensed 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 $17.8 million, subject to purchase price adjustments. The purchase consideration was primarily attributable to non-deductible goodwill of $11.4 million, with the remainder allocated to acquired technology and other assets.

Recent Accounting Pronouncements

Recent Accounting Pronouncements 

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”), which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate or by another reference rate expected to be discontinued. The amendments are effective for all entities through December 31, 2022 and can be adopted as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020. The adoption of the amendment did not have a material impact on the Company’s condensed consolidated financial statements.
