We discuss many of these risks in Item 1A of this Annual Report on Form 10-K in greater detail under the heading “Risk Factors” and in other filings

we make from time to time with the Securities and Exchange Commission, or SEC. Also, these forward-looking statements represent our estimates and
assumptions only as of the date of this Annual Report on Form 10-K, 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.

PART I

Item 1. Business

Overview

The Trade Desk, Inc. (the “Company,” “we,” “our,” or “The Trade Desk”) is 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, in-app, 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 display advertising. Since launching, we added support for several additional advertising

formats, and in 2019, approximately 79% of gross spend on our platform came from mobile, video (which includes CTV), 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.

The Trade Desk is a Delaware corporation established in 2009, headquartered in Ventura, California.

Our Industry

We believe that several trends in the advertising industry, happening in parallel, are driving a shift to programmatic advertising – the selling and

buying of advertising inventory electronically.

Some of the key industry trends are:

Media is Becoming Digital. Media is increasingly becoming digital as a result of advances in technology and changes in consumer behavior. This shift

has enabled unprecedented options for advertisers to target and measure their advertising campaigns across nearly every media channel and device. The
digital advertising market is a significant and growing part of the total advertising market. We believe that the market is evolving and that advertisers will
shift more spend to digital media. Since media is becoming increasingly digital, decisions based on consumer and behavioral data are more prevalent.

Fragmentation of Audience. As digital media grows, audience fragmentation is accelerating. A growing “long tail” of mobile applications (apps),

media players, websites and content presents a challenge for advertisers trying to reach a large audience. Audience fragmentation has substantially impacted
TV content distribution, perhaps more than any other channel, which we believe is changing how TV advertising inventory is monetized. Mirroring the
fragmentation occurring in content, the number of devices used by individual consumers has increased. Both of these fragmentation trends are opportunities
for technology companies that can consolidate and simplify media buying options for advertisers and their agencies.

Convergence of TV and the Internet. While still in its early days, we are witnessing a generational shift from linear TV to CTV with the convergence

of the internet and television programming. New technologies allow more video content to be delivered over the Internet more seamlessly, accelerating
consumer demand to watch what they want, when they want and where they want. The anticipated worldwide rollout of 5G, the fifth generational standard for
wireless networks, will bring significantly faster data transfer speeds with less latency, and a better user experience, to consumers of mobile video. We believe
these technologies will continue to feed consumer demand for CTV (including mobile video) and bring about new opportunities for content owners and
advertisers to connect with consumers.

Increased Use of Data. Advances in software and hardware and the growing use of the Internet have made it possible to collect and rapidly process

massive amounts of user data. Data vendors are able to collect user information across a wide range of Internet properties and connected devices, aggregate it
and combine it with other data sources. This data is then made non-identifiable and available within seconds based on specific parameters and attributes.
Advertisers can integrate this targeting data with their own or an agency’s proprietary data relating to client attributes, the advertisers’ own store locations and
other related characteristics. Through the use of these types of data sources, together with real-time feedback on consumer reactions to the ads, programmatic
advertising increases the value of impressions for advertisers and inventory owners, and viewers receive more relevant ads.

Automation of Ad Buying. The growing complexity of digital advertising has increased the need for automation. Technology that enables fast,
accurate and cost-effective decision-making through the application of computer algorithms that use extensive data sets has become critical for the success of
digital advertising campaigns. Using programmatic inventory buying tools, advertisers are able to automate their campaigns, providing them with better price
discovery, on an impression-by-impression basis. As a result, advertisers are able to bid on and purchase the advertising inventory they value the most, pay
less for advertising inventory they do not value as much, and abstain from buying advertising inventory that does not fit their campaign parameters.

Digital Advertising Eco-System

The digital advertising eco-system is divided into buyers, sellers and marketplaces, which can be further segmented on the basis of whether
participants provide services or technology. We believe that participants on the buy-side or sell-side should be advocates for their buyers or sellers, while
those in the market business should act as a referee or have market-driven incentives to protect or enhance the integrity of the marketplace. We believe that
there are inherent conflicts of interest when market participants serve both buyers and sellers.

What We Do

We empower ad buyers, by providing a self‑service omnichannel software platform that enables our clients to purchase and manage data‑driven digital

advertising campaigns. Our platform allows clients to manage integrated advertising campaigns across various advertising channels and formats, including
display, video, audio, native and social, on a multitude of devices, including computers, mobile devices, and CTV.

We Are Exclusively Focused on the Buy-Side. We focus on buyers since they control the advertising budgets. Also, the supply of digital
advertising inventory exceeds demand, and accordingly, we believe it is a buyer’s market. We also believe that by aligning our business only
with buyers, we are able to avoid inherent conflicts of interest that exist when serving both the buy-side and sell-side. This focus allows us to
build trust with clients, many of whom leverage their proprietary data on our platform. That trust and ability to use their own data on our
platform, without worrying about it being used by other participants, enables our clients and their advertisers to achieve better results. This trust
provides us the benefit of long-term and stable relationships with our clients.

We Are an Enabler, Not a Disruptor. With our platform, we enable advertising agencies and other service providers. Advertisers can benefit
from a comprehensive solution that combines our platform with the services provided by advertising agencies.

We Are Data-Driven. Our platform was founded on the principle that data-driven decisions will be the future of advertising. We built a data
management platform first, before building our ad buying technology. While data from disparate third-party data providers can improve
campaign performance, our clients’ success often relies largely on our ability to ingest proprietary data directly from brands and their agencies
to enable intelligent decisioning that optimizes advertising campaigns. Given our independent, buy-side focused approach, and our strict
protocol of carefully earmarking all client first-party data we ingest onto our data management platform, our clients trust us with their most
granular and expressive data. Our technology platform enables the effective use of this granular data, which allows our clients to run precisely
targeted advertising campaigns that maximize their return on advertising investments. Additionally, we are able to better optimize campaigns by
using the data streams that we capture across different devices, so that data from one channel can be used to inform another. The breadth of data
that we collect from a multitude of data sources across channels gives our clients a holistic view of their target audiences, enabling more
effective targeting across different channels.

We Do Not Arbitrage Advertising Inventory. To further align our interests with those of our clients, we do not buy advertising inventory in
order to resell it to our clients for a profit. Instead, we provide our clients with a platform that allows them to manage their omnichannel
advertising campaigns, on a self-serve basis with robust reporting. With our platform, our clients control their campaign spend and are able to
access and choose from many inventory sources.

We Have Ongoing Relationships with Clients. We derive substantially all of our revenue from ongoing MSAs with our clients rather than
episodic insertion orders. We believe that this approach helps us strengthen our relationships with our clients and grow their use of our platform
over the long term, providing us with a highly scalable business model.

We Are a Clear Box, Not a Black Box. Our platform is transparent and shows our clients their costs of advertising inventory, data, our platform
fee and detailed performance metrics on their advertising campaigns. Our clients directly access and execute campaigns on our platform,
control all facets of inventory purchasing decisions, and receive detailed, real-time reporting on all their advertising campaigns. By providing
transparent information on our platform, our clients are able to continually compare results and target their budgets to the most effective
advertising inventory, data providers and channels.

We Are an Open Platform. Clients can customize and build their own features on top of our platform. Clients may use our APIs to, for
example, design their own user interface, bulk manage advertising campaigns, and link other systems including ad servers or reporting tools.
Using our APIs or by working with our engineering team, clients invest their own resources to build their own proprietary tools in areas
including reporting, campaign strategy, custom algorithms or proprietary data use cases. Our open platform approach enables our advertising
agency and service provider clients to provide differentiated offerings to their clients, which we believe leads to long-term relationships and
increased use of our platform.

Our Platform

At the core of our platform is our bid-factor based architecture, which we believe has advantages over line-item based architectures that other buy-side

systems use. Our bid-factor based system allows users to define desirable factors and the value associated with those factors. Based on these factors, our
platform can compute in real-time the value of impressions and bid only for optimal impressions. Because of the granularity of the bid factors, users of our
platform can rapidly create billions of different bid permutations with only a few clicks. This expressiveness enables better targeting, pricing and campaign
results.

Our platform is useful and user-friendly based on the following:

•

•

•

Easy to Use, Open and Customizable. Our platform provides multiple, easy-to-use automation tools that help our users focus on managing the
key factors affecting their campaigns. Our platform also enables clients to integrate custom features and interfaces for their own use through our
APIs.

Expressiveness. Our platform allows clients to easily define and manage advertising campaigns with multiple targeting parameters that may
result in quadrillions of permutations, which we refer to as expressiveness. We believe that expressiveness provides clients with the ability to
target audiences with an extremely high level of precision and thus obtain higher returns on their advertising spend.

Integrated, Omnichannel and Cross-device. Our platform provides integrated access to a wide range of omnichannel inventory and data
sources, as well as third-party services such as ad servers, ad verification services and survey vendors. Our platform’s integration of these
sources and services enables our clients to deploy their budgets through a wide variety of channels, media screens and formats, targeted in their
desired manner, through a single platform.

Some of the key features of our platform are:

•

•

•

•

•

•

Auto-Optimization. We provide auto-optimization features which allow buyers to automate their campaigns and support them with computer
generated modeling and decision making. In addition, by giving clients full reporting, budgeting, and bidding transparency, clients can take
control of targeting variables when desired, and apply algorithmic automation when appropriate.

Advanced Reporting and Analytics Tools. We provide a comprehensive view of consumers’ interactions with the ads purchased through our
platform with robust reporting of performance insights across multiple variables, such as audience characteristics, ad format, site category,
website, device, creative type, and geography. Better reporting results in better learning, often leading to better campaign optimization and
outcomes.

Data Management. Our platform enables clients to license a broad selection of data from third-party vendors in a seamless and easy manner,
allowing them to further optimize their campaigns with the most relevant data.

Koa Artificial Intelligence. A predictive engine that helps platform users make data-driven decisions without sacrificing control or
transparency. Koa makes recommendations for campaign optimizations based on its sophisticated analysis of rich data sets. Advertisers can
then choose which optimizations make the most sense for their campaigns.

Media Planner. An omnichannel solution designed for digital media professionals to generate, analyze, and launch data-driven, programmatic
media plans. This tool analyzes the actions of existing core audiences with the data we see across the open internet to deliver a fully
transparent, performance-focused, and ready-to-activate campaign.

Private Marketplace Support. For clients who wish to transact directly with individual publishers, we offer a comprehensive user interface for
discovering and transacting via a wide variety of private contracts. Additionally, we offer a solution for advertisers to access publisher
inventory via a direct tag in a publisher’s ad server where there is no other programmatic access to such publisher’s inventory.

Our platform enables a media planner or buyer at an advertising agency to:

•

•

•

•

•

•

•

purchase digital media programmatically on various media exchanges and sell-side platforms;

acquire and use third-party data to optimize and measure digital advertising campaigns;

integrate and deploy their proprietary first-party data with our platform in order to optimize campaign efficacy;

monitor and manage ongoing digital advertising campaigns on a real-time basis;

link digital campaigns to offline sales results or other business objectives;

access other services such as our data management platform and publisher management platform marketplace; and

use our user interface and APIs to build their own proprietary technology on top of our platform.

Our Technology

The core elements of our technology are:

•

•

•

•

Scalable Architecture. Our platform infrastructure is hosted in data centers in eight countries around the world. On average, our real-time
bidding technology evaluates more than 790 billion ad opportunities per day, reaching over 819 million devices per day on a global basis. Our
core bidding architecture is easily adaptable to a variety of inventory formats, allowing our platform to communicate with many different
inventory sources.

Predictive Models. We use the massive data captured by our platform to build predictive models around user characteristics, such as
demographic, purchase intent or interest data. Data from our platform is continually fed back into these models, which enables them to improve
over time as the use of our platform increases.

Performance Optimization. During campaign execution, our optimization engine continually scores a variety of attributes of each impression,
such as website, industry vertical or geography, for their likelihood to achieve campaign performance goals. Our bidding engine then shifts bids
and budgets in real-time to deliver optimal performance. Additionally, our platform enables clients to set multiple, simultaneous optimization
goals for their advertising.

Real-time Analytics. Our platform continuously collects data regarding inventory availability. Real-time campaign delivery and spend totals are
used to manage campaign budgets and goal caps, as well as campaign reporting. This data is fed back into our optimization engine to improve
campaign performance, and into machine-learning models for user demographic predictive modeling.

Our Growth Strategy

The key elements of our long-term growth strategy include:

•

•

•

•

•

•

Increase Our Share of Existing Clients’ Digital Advertising Spend. Many advertisers are moving a greater percentage of their advertising
budgets to programmatic channels. We believe that this shift will provide us with the opportunity to capture a larger share of the overall
advertising spend by our existing clients. Additionally, we plan to promote additional services and data to our clients, helping us grow our
business.

Grow Our Client Base. We have extensive relationships with many advertising agencies and other service providers, and believe that, given the
decentralized nature of the advertising industry, we have the opportunity to expand our relationships within these agencies and with additional
agencies and service providers. We expect to continue making investments in growing our sales and client service team to support this strategy.

Expand Our Omnichannel Capabilities. We believe offering clients capabilities across all media channels and devices enables advertisers to
manage omnichannel campaigns and use data from each channel to inform decisions in other channels. We believe these capabilities will
continue to further strengthen our relationships with our clients. We intend to continue to invest in innovation across all channels, including the
integration of new inventory sources within CTV, digital radio, social, native, and digital out of home.

Extend Our Reach in CTV. Television is the largest category of advertising spend, and we believe that the future of television is in streaming
media and video on demand through subscription services and connected devices. We plan to invest significant resources in technology, sales
and support staff related to our CTV growth initiatives.

Continue to Innovate in Technology and Data. We intend to continue to innovate in technology to improve our platform and enhance its
features and functionalities. We view data as one of our key competitive advantages. We will continue to invest resources in growing our data
offerings, both from third-party providers as well as our proprietary data.

Expand Our International Presence. Many of our clients serve advertisers on a global basis and we intend to expand our presence outside of
the United States, or U.S., to serve the needs of those advertisers in additional geographies. As we expand relationships with our existing
clients, we are investing in select regions in Europe and Asia. In particular, we believe that China and Indonesia may represent substantial
growth opportunities, and we are investing in developing our business in those markets.

Our Clients

Our clients consist of purchasers of programmatic advertising inventory and data. As of December 31, 2019, we had approximately 820 clients,
consisting primarily of advertising agencies or groups within advertising agencies that have independent relationships with us, manage budgets independently
of one-another, are based in different jurisdictions, and are served by unique Trade Desk teams. 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. Our client count includes only those parties which have signed MSAs with us and have spent more than $20,000 on our platform.

7

 
 
 
 
 
 
 
 
 
 
If all of our individual client contractual relationships were aggregated at the holding company level, two clients would have each represented more
than 10% of our gross billings in 2019, two clients would have each represented more than 10% of our gross billings in 2018 and three clients would have
each represented more than 10% of our gross billings in 2017. Our contractual and billing arrangement with Omnicom Group Inc. is at the holding company
level and accounted for 10% of our gross billings in 2019, 10% in 2018 and 11% in 2017. For Publicis Groupe and WPP plc, we enter into separate contracts
and billing relationships with various of its individual agencies and account for them as separate clients. We do not have any contractual relationship with
Publicis Groupe or the holding company WPP plc. Publicis Media Inc. (formerly VivaKi, Inc.), which is affiliated with Publicis Groupe, accounted for 13%
of our gross billings in 2019, 20% in 2018 and 22% in 2017. Mindshare, which is affiliated with WPP plc, accounted for 10% of our gross billings in 2017.

Our clients typically enter into MSAs with us that give users constant access to our platform. The MSAs do not contain any material commitments on
behalf of clients to use our platform to purchase ad inventory, data or other features. These MSAs typically have one-year terms that renew automatically for
additional one-year periods, unless earlier terminated. The MSAs are typically terminable at any time upon 60 days’ notice by either party.

Our clients are loyal, as reflected by our client retention rate of over 95% in 2019, 2018 and 2017. In addition, our clients typically grow their use of

our platform over time.

Our Advertising and Data Inventory Suppliers

For suppliers of programmatic advertising inventory and data, we believe that we are an important business partner, as we represent one of the largest

sources of buy-side demand within the digital advertising industry.

We obtain digital advertising inventory from over 95 ad exchanges, supply-side platforms, publishers and ad networks, providing us with access to a

breadth of programmatic advertising inventory across computers, mobile devices and CTV. On average each day, our platform provides our clients with
access to over 790 billion ad impressions per day, reaching over 819 million devices per day on a global basis.

For third-party data vendors, we believe that we represent an important distribution channel. As of December 31, 2019, we have integrated our

platform with over 194 third-party data vendors whose products we make available for purchase through our platform.

Sales and Marketing

Given our self-serve business model, we focus on supporting, advising and training our clients to use our platform independently as soon as they are

ready to transact.

Once a new client has access to our platform, they work closely with our client service teams, which onboard the new client and provide continuous

support throughout the early campaigns. Typically, once a client has gained some initial experience, it will move to a fully self-serve model and request
support as needed.

To help train our clients, suppliers and other digital media participants, we have created an e-learning program called The Trading Academy. We

believe that this initiative is an important component in our strategy of enabling rapid onboarding to our platform.

Our marketing efforts are focused on increasing awareness for our brand, executing thought-leadership initiatives, supporting our sales team and
generating new leads. We seek to accomplish these objectives by presenting at industry conferences, hosting client conferences, publishing white papers and
research, public relations activities, social media presence and advertising campaigns.

Technology and Development

Rapid innovation is a core driver of our business success and our corporate culture. We prioritize and align our product roadmap with our clients’

needs, and we aim to refresh our platform weekly. Our development teams are intentionally lean and nimble in nature, providing for transparency and
accountability.

We expect technology and development expense to increase 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 ramp up the volume of advertising spending on our platform. We also
intend to invest in technology to further automate our business processes.

Seasonality

In the advertising industry, companies commonly experience seasonal fluctuations in revenue. For example, many advertisers allocate the largest
portion of their budgets to the fourth quarter of the calendar year in order to coincide with increased holiday purchasing. Historically, the fourth quarter of the
year reflects our highest level of advertising activity and the first quarter reflects the lowest level of such activity. We expect our revenue to continue to
fluctuate based on seasonal factors that affect the advertising industry as a whole.

Our Competition

Our industry is highly competitive and fragmented. We compete with other demand-side platform providers, some of which are smaller, privately-held

companies and others are divisions of large, well-established companies such as AT&T, Google and Adobe. We believe that we compete primarily based on
the performance, capabilities and transparency of our platform and our focus on the buy-side. We believe that we are differentiated from our competitors in
the following areas:

•

•

•

•

•

we are an independent technology company focused on serving advertising agencies and others on the buy-side of our industry;

our client relationships are based on MSAs as opposed to campaign-specific insertion orders;

our platform provides comprehensive access to a wide range of inventory types and third-party data vendors;

our platform allows clients to build proprietary advantages by integrating custom features and interfaces for their own use through our APIs;
and

our technology provides highly expressive targeting.

In addition, we believe that new entrants would find it difficult to gain direct access to inventory providers, given their limited scale and the costs that

additional integrations impose on inventory providers.

Our Employees and Culture

We have employees and offices around the world to serve advertisers’ desire to communicate with consumers worldwide.

Our business and our culture are anchored on four core principles:

•

•

No company can effect global change without passionate forward‑thinking people as both employees and clients.

By preserving an honest and transparent culture and avoiding client conflict, we can exert exponentially less effort to grow our business.

We have committed to our clients and employees that we will never stop innovating.

Being profitable and changing the world can co‑exist and is more likely to happen when striving for both simultaneously.

We believe we attract talented employees to our company and sophisticated ad buyers to our platform in large part because of our vision and

unwavering commitment to empower the buy‑side of advertising.

As of December 31, 2019, we had 1,310 employees, of whom 851 are in the U.S. Our team draws from a broad spectrum of backgrounds and
experiences, across technology, advertising and securities trading and other areas. We foster an entrepreneurial culture so that we may remain focused and
innovative over time, as we strive to serve our clients with openness, transparency and humility.

Development of International Markets

We have been increasing our focus on markets outside the U.S. to serve the global needs of our clients. We believe that the global opportunity for

programmatic advertising is significant, and should continue to expand as publishers and advertisers outside the U.S. seek to adopt the benefits that
programmatic advertising provides. To capitalize on this opportunity, we intend to continue investing in our presence internationally. Our growth and the
success of our initiatives in newer markets will depend on the continued adoption of our platform by our existing clients, as well as new clients, in these
markets. Information about our geographic gross billings is set forth in Note 12 of “Item 8. Financial Statements and Supplementary Data” in this Annual
Report on Form 10-K.

Intellectual Property

The protection of our technology and intellectual property is an important component of our success. We rely on intellectual property laws, including

trade secret, copyright, patent and trademark laws in the U.S. and abroad, and use contracts, confidentiality procedures, non-disclosure agreements, employee
disclosure and invention assignment agreements and other contractual rights to protect our intellectual property. We have patent applications that are pending,
however, historically, we have not patented our proprietary technology in order to keep our technology architecture, trade secrets, and engineering roadmap
private. Our patent applications may not result in the issuance of any patents, and any issued patents may not actually provide adequate defensive protection
or competitive advantages to us. Our ability to continually develop new intellectual property and deliver new functionality quickly serves to protect us against
competitors in digital advertising technology. We believe our platform is difficult to replicate and would be expensive and time-consuming to build.

Collection and Use of Data; Privacy and Data Protection Legislation and Regulation

We and our clients currently use pseudonymous data about Internet users on our platform to manage and execute digital advertising campaigns in a

variety of ways, including delivering advertisements to Internet users based on their geographic locations, the type of device they are using, their interests as
inferred from their web browsing or app usage activity, or their relationships with our clients. Such data is passed to us from third parties, including original
equipment manufacturers, application providers, and publishers. We do not use this data to discover the identity of individuals, and we currently prohibit
clients, data providers and inventory suppliers from importing data  that directly identifies individuals.

Our ability, like those of other advertising technology companies, to collect, augment, analyze, use and share data relies upon 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. The processes used to identify devices and similar and associated technologies are governed by U.S. and foreign laws and
regulations and dependent upon their implementation within the industry ecosystem. Such laws, regulations, and industry standards may change from time to
time, including those relating to the level of consumer notice and consent required before a company can employ cookies or other electronic tools to collect
data about interactions with users online.

In the U.S., both federal and state legislation govern activities such as the collection and use of data, and privacy in the advertising technology industry

has frequently been subject to review by the Federal Trade Commission (the “FTC”), U.S. Congress, and individual states. Much of the federal oversight on
digital advertising in the U.S. currently comes from the FTC, which has primarily relied upon Section 5 of the Federal Trade Commission Act, which
prohibits companies from engaging in “unfair” or “deceptive” trade practices, including alleged violations of representations concerning privacy protections
and acts that allegedly violate individuals’ privacy interests. However, there is increasing consumer concern over data privacy in recent years, which has led
to a myriad of proposed legislation and new legislation both at the federal and state levels, some of which has affected and will continue to affect our
operations and those of our industry partners. For example, the California Consumer Privacy Act of 2018 (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, if there is potential that individuals can be identified by
such 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 some to include common advertising
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 to 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.

As our business is global, our activities are also subject to foreign legislation and regulation. In the European Union (including the European
Economic Area (the “EEA”), countries of Iceland, Liechtenstein and Norway), or EU, separate laws and regulations (and member states’ implementations
thereof) govern the processing of personal data, and these laws and regulations continue to impact us. The General Data Protection Regulation(“GDPR”),
which applies to us, came into effect on May 25, 2018. Like the CCPA, 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), however European regulators have questioned the framework’s viability
and activists have filed complaints with regulators of alleged non-compliance by specific companies that employ the framework. Continuing to maintain
compliance with the GDPR’s requirements requires significant time, resources and expense, and may lead to significant changes in our business operations.

10

Additionally in the EU, 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 provided consent. 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. Although it remains under 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 cannot yet determine the impact such future laws, regulations, and standards may have on our business.

For the transfer of personal data from the EU to the U.S., we rely upon, and are currently certified under, the EU-U.S. and Swiss-U.S. Privacy Shield

Frameworks. The Privacy Shield Framework, however, is facing criticism from privacy advocates and legal challenges in E.U. courts, as are other EU
mechanisms for adequate data transfer to the U.S. such as the standard contractual clauses. If successful challenges leave us 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 US, 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 need to divert resources from other aspects of
our operations.

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. If a “Do Not Track” standard is imposed by state, federal, or foreign
legislation, adopted by many Internet users, or agreed upon by standard setting groups, we may have to change our business practices.

We participate in several industry self-regulatory programs, mainly initiated by the Network Advertising Initiative, or NAI, the Digital Advertising
Alliance, or DAA, and their international counterparts. Our efforts to comply with the self-regulatory principles of these programs include offering Internet
users notice and choice when advertising is served to them based, in part, on their interests. We believe that this user-centric approach to addressing consumer
privacy empowers consumers to make informed decisions on the use of their data.

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 Annual Report, including the 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 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.

We had approximately 820 clients, consisting primarily of advertising agencies, as of December 31, 2019. 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 Omnicom Group Inc. would each represent more than 10% of our gross billings for 2019.

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

12

artificial intelligence and machine learning, 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, reducing 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. Growth in spend may outpace growth in our revenue as

the market for programmatic buying for advertising matures 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 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, such as analytics, automated media buying and exchanges, aimed at capturing advertising
spend or disrupting the digital marketing landscape.

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.

13

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 bad
debt.

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 bad debt, which could harm our results of operations. In the future, bad debt may exceed reserves
for such contingencies and our bad debt exposure may increase over time. Any increase in write-offs for bad debt 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. 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, demand for our platform could decrease, and our business, financial condition, and results of operations could be
adversely affected.

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

14

 
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.

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, such as CTV, become available, we will need to expend significant resources to ensure we have access to such new
inventory. 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 their advertising budgets, which could reduce spend though our platform and
adversely affect our business, financial condition and results of operations. 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
masked the impact of seasonality, but if our growth rate declines or seasonal spending becomes more pronounced, seasonality could have a more significant
impact on our revenue, cash flow and results of operations from period to period.

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.

15

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;

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

changes the pricing or availability of inventory, data or other third-party services;

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 through real-time advertising exchanges or in the cost of reaching end
consumers through digital advertising;

disruptions or outages on our platform;

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; and

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 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.

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. 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;

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

16

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

•

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 consumer privacy compliance, including additional infrastructure, automation and personnel; and

explore strategic acquisitions.

Investing in the foregoing, however, may not yield anticipated returns. Consequently, as our costs increase, we may not be able to generate sufficient

revenue to sustain profitability.

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 (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 our 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.

We allow our clients to utilize application programming interfaces, or 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 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.

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,

18

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. While we contractually prohibit clients, data providers and inventory suppliers form importing or otherwise providing
information that directly identifies individuals on our platform, if a partner provided such information in violation of our policies and our systems are
breached, we could be subject to contractual breach and indemnification claims from other clients and partners. 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.

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.

Recently, the State of California adopted a law broadly regulating businesses’ processing of personal information, the California Consumer Privacy

Act of 2018, or CCPA, which went into effect January 1, 2020. The CCPA’s definition of “personal information” is broad 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, if there is potential that individuals can be identified by such 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 some to include common advertising 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 to 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 California Attorney General has proposed regulations implementing the CCPA that could impose further limitations. Although we have attempted

to mitigate certain risks posed by the CCPA through contractual and platform changes, we cannot predict the timing or outcome of the California Attorney
General’s rulemaking or the effect of the CCPA and its implementing regulations on our business. Responding to requirements under the CCPA and the
proposed regulations will continue to affect our operations (and those of our industry partners).

Laws governing the processing of personal data in Europe (including the European Union and European Economic Area, or EEA, and the countries of

Iceland, Liechtenstein, and Norway) also continue to impact us. The General Data Protection Regulation, or GDPR, which applies to us, came into effect on
May 25, 2018. Like the CCPA, 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.
Continuing to maintain compliance with the GDPR’s requirements 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.

Regulatory investigations and enforcement actions could also impact us. In the U.S., the Federal Trade Commission, or 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, including, in
Europe, a 2016 inquiry into Criteo’s compliance with French

19

data privacy laws. 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 involve 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 the CCPA and its implementing regulations and to the enhanced 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.
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 including the CCPA and the GDPR 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.

Uncertainty caused by lack of uniformity among laws to which we are or may become subject and instability in the global legal landscape may cause us to
incur additional or unexpected costs and legal risk, increase our risk of reputational harm, or cause us to change our platform or business model.

We cannot predict the future of the regulatory landscape regarding the protection of personal information. 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 U.S., a federal privacy law is the subject of active discussion and several bills have been
introduced. Additionally, industry groups in the U.S. and their international counterparts have self-regulatory guidelines that are subject to periodic updates to
which we have agreed to adhere. High profile incidents involving breaches of personal information or misuse of consumer information may increase the
likelihood of new U.S. federal, state, or international laws or regulations in addition to those set out above, and such laws and regulations may be inconsistent
across jurisdictions.

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 have already seen publishers impose varying 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 like 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.

Changes in data residency and cross-border transfer restrictions also impact our operations. For the transfer of personal data from the EU to the U.S.,
we rely upon, and are currently certified under the EU-U.S. and Swiss-U.S. Privacy Shield Frameworks. The Privacy Shield Framework, however, continues
to face criticism from privacy advocates and legal challenges in EU courts, as do other EU mechanisms for adequate data transfer such as the standard
contractual clauses. If successful challenges leave us 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 US, 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 recent withdrawal of the United Kingdom, or 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. Although we will apply the guidance from the Department of Commerce regarding post-Brexit data transfers
from the U.K. through Privacy Shield, it remains uncertain whether other methods of transfer will have to be implemented. Accordingly, we cannot predict
the additional expense, impact on revenue, or other business impact that may stem from Brexit.

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.

20

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 NAI’s Code of Conduct and the DAA’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 Internet-based 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, 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.

21

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 recently announced plans to deprecate support for
third-party cookies and user agent strings entirely within two years. 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 IAB and DAA
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.

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 recent 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 current draft regulations contemplate browser-based or similar “do not sell” signals. If 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 (such as the proposed ePrivacy Regulation
or CCPA regulations), 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, the CCPA, “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.

22

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-serve 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.

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 events such as earthquakes, fires, floods,
power loss, telecommunications failures 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.

23

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 U.S., 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, 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, or CPI, of the Transparency
International. Our teams in locations outside the U.S. are substantially smaller than some of our teams in the U.S. 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 U.S., advertising buyers and
inventory and data providers may be less familiar with DSPs and our brand, and business models may not support our value proposition;

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, tax and withholding (including overlapping of different tax regimes),
varied labor and employment laws (including those relating to termination of employees); corporate formation and other regulatory limitations
or obligations on our operations (such as obtaining requisite licenses), 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;

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.

24

 
 
 
 
 
 
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 U.S. 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 U.S. are not as developed as
those within the U.S., 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.

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.

We are exposed to fluctuations in the market values of our investments.

Credit ratings and pricing of our investments can be negatively affected by liquidity, credit deterioration or losses, financial results, foreign exchange

rates, changes in interest rates, or other factors. As a result, the value and liquidity of our cash, cash equivalents and marketable securities may fluctuate
substantially. Although we have not realized any significant losses on our cash, cash equivalents or marketable securities, future fluctuations in their value
could result in a significant realized loss, which could adversely affect our financial condition and results of operations.

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.

25

 
 
 
 
 
 
 
 
 
 
 
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.

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 limited 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.

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 U.S. 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

26

 
 
 
 
 
 
 
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.

Our management team has limited experience managing a public company.

We became a public company in September 2016. Most members of our management team have limited experience managing a publicly traded
company, interacting with public company investors, and complying with the increasingly complex laws, rules and regulations that govern public companies.
As a public company, we are subject to significant obligations relating to reporting, procedures and internal controls, and our management team may not
successfully or efficiently manage such obligations. These obligations and scrutiny will require significant attention from our management and could divert
their attention away from the day-to-day management of our business, which could adversely affect 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.

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 U.S. 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 U.S. 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

27

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 U.S., 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 client 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.

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 “FCPA”), 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.

28

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.

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 have enacted or are considering enacting 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.

Risks Related to Ownership of Our Class A Common Stock

The market price of our Class A common stock may be volatile or may decline regardless of our operating performance, and you may not be able to resell
your shares at or above your purchase price.

The market price of our stock and of equity securities of technology companies has historically experienced high levels of volatility. If you purchase

shares of our Class A common stock, you may not be able to resell those shares at or above your purchase price. The market price of our Class A common
stock has fluctuated and may fluctuate significantly in response to numerous factors, some of which are beyond our control and may not be related to our
operating performance, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

announcements of new offerings, products, services or technologies, commercial relationships, acquisitions or other events by us or our
competitors;

price and volume fluctuations in the overall stock market from time to time;

significant volatility in the market price and trading volume of technology companies in general and of companies in the digital advertising
industry in particular;

fluctuations in the trading volume of our shares or the size of our public float;

actual or anticipated changes or fluctuations in our results of operations;

whether our results of operations meet the expectations of securities analysts or investors;

actual or anticipated changes in the expectations of investors or securities analysts;

litigation involving us, our industry, or both;

regulatory developments in the U.S., foreign countries, or both;

general economic conditions and trends;

major catastrophic events;

sales of large blocks of our common stock;

departures of key employees; or

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

30

 
 
 
 
 
 
 
 
 
 
 
 
 
 
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, which is the stock we offered in our initial public offering, 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.
Stockholders who hold shares of Class B common stock, including our executive officers, employees, and directors and their affiliates, together hold
approximately 56% of the voting power of our outstanding capital stock as of December 31, 2019. This concentrated control limits or precludes your ability
to influence corporate matters for the foreseeable future. These stockholders are able to influence or control matters requiring approval by our stockholders,
including the election of directors 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.

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, 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.

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.

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;

eliminate the ability of our stockholders to call special meetings of stockholders;

specify that special meetings of our stockholders can be called only by our board of directors, the chairman of our board of directors, or our
chief executive officer;

prohibit stockholder action by written consent, which 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.

Item 3. 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.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our Class A common stock began trading on the NASDAQ Global Market on September 21, 2016 under the symbol “TTD”. Prior to this date, there

was no public trading market for our Class A common stock. There is no public trading market for our Class B common stock.

Holders of Record

As of January 31, 2020, there were approximately 15 holders of record of our Class A common stock and 21 holders of record of our Class B common
stock. The actual number of stockholders is greater than this number of record holders and includes stockholders who are beneficial owners but whose shares
are held in street name by brokers and other nominees. This number of holders also does not include stockholders whose shares may be held in trust by other
entities.

Dividend Policy

We have never declared or paid any dividends on our Class A or Class B common stock, and we do not anticipate paying any cash dividends in the

foreseeable future. We currently intend to retain any earnings to finance the operation and expansion of our business. Any future determination to pay
dividends will be at the discretion of our board of directors and will be dependent upon then-existing conditions, including our earnings, capital requirements,
results of operations, financial condition, business prospects and other factors that our board of directors considers relevant. Refer to “Item 7. Management’s
Discussion and Analysis of Financial Condition and Results of Operations” for additional information regarding our financial condition. In addition, our
credit facility contains restrictions on our ability to pay dividends.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

None.

Recent Sales of Unregistered Securities

None.

Stock Performance Graph

This performance graph shall not be deemed “soliciting material” or to be “filed” with the SEC for purposes of Section 18 of the Exchange Act, or

otherwise subject to the liabilities under that Section, and shall not be deemed to be incorporated by reference into any filing of ours under the Securities Act
of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.

The following graph compares the cumulative total stockholder return on an initial investment of $100 in our Class A common stock between

September 21, 2016 (our initial trading day) and December 31, 2019, with the comparative cumulative total returns of the Standard & Poor’s (S&P) 500
Index, Russell 3000 Index and NASDAQ 100 Index over the same period. As previously discussed, we have not paid any cash dividends and, therefore, the
cumulative total return calculation for us is based solely upon stock price appreciation (depreciation) and not reinvestment of cash dividends, whereas the data
for the S&P 500 Index, Russell 3000 Index and NASDAQ 100 Index assumes reinvestments of dividends. The graph assumes the closing market price on
September 21, 2016 of $30.10 per share as the initial value of our Class A common stock. The returns shown are based on historical results and are not
necessarily indicative of, nor intended to forecast, future stock price performance. The performance graph also includes a comparison with the Russell 2000
Index, which we are now replacing with the Russell 3000 Index because it is the relevant index in which the Company is now included.

Gross spend includes the value of a client’s purchases through our platform plus our platform fee, which is a percentage of a client’s purchases through
the platform. We review gross spend for internal management purposes to assess market share and scale, and to plan for optimal levels of support for
our clients. Some companies in our industry report revenue on a gross basis or use similar metrics, so tracking our gross spend allows us to compare
our results to the results of those companies. Gross spend does not represent our revenue reported on a GAAP basis. Our gross spend is influenced by
the volume and characteristics of bids for advertising inventory won through our platform. We expect our revenue as a percentage of gross spend,
which is sometimes referred to as take rate, to fluctuate due to the types of services and features selected by our clients through our platform and
certain volume discounts. We track gross spend based on the location of our office servicing the respective clients. Other companies, including
companies in our industry, may calculate gross spend or similarly titled measures differently, which reduces its usefulness as a comparative measure.

Gross billings represents the amount we invoice our clients, net of allowances. As some of our clients have payment relationships directly with
advertising inventory suppliers for the amount of advertising inventory the clients purchase through our platform, we do not invoice these clients for
this spend, and we only invoice such clients for data, other services and our platform fee. Accordingly, gross billings are less than gross spend and
represent gross spend, less platform discounts and less the value of advertising inventory and data that our clients purchase directly from publishers
through our platform. We report revenue on a net basis which represents gross billings net of amounts we pay suppliers for the cost of advertising
inventory, data and add-on features. We expect our revenue as a percentage of gross billings to fluctuate due to the types of services and features
selected by our clients through our platform and certain volume discounts. We review gross billings for internal management purposes to adequately
plan for our working capital needs and monitor collection risk. We track gross billings based on the billing address of the client. In many cases,
international clients are serviced from our U.S. offices resulting in gross billings exceeding gross spend for international clients.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with the consolidated financial

statements and the related notes to those statements included in Item 8 to this Annual Report on Form 10-K. In addition to historical financial information,
the following discussion contains forward-looking statements that reflect our plans, estimates, beliefs, and expectations, and involve risks and uncertainties.
Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report on Form 10-K, particularly in
the section titled “Item 1A. Risk Factors” and the “Special Note About Forward-Looking Statements”.

The following generally discusses 2019 and 2018 items and year-to-year comparisons between 2019 and 2018. Discussion of historical items and

year-to-year comparisons between 2018 and 2017 that are not included in this discussion can be found in “Management’s Discussion and Analysis of
Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 filed with SEC on
February 22, 2019. References to “Notes” are notes included in our consolidated financial statements appearing elsewhere in this Annual Report on Form
10-K.

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, including display, video, audio, native and social, on a multitude of
devices, such as computers, mobile devices, and CTV. Our platform’s integrations with major data, inventory, and publisher partners provides ad buyers reach
and decisioning capabilities, and our enterprise APIs enable our clients to develop on top of the platform.

We commercially launched our platform in 2011, targeting display advertising. We have since extended our platform to address additional advertising

formats, and in 2019, approximately 79% of gross spend on our platform was for mobile, video, audio, native and social.

Our clients are primarily the advertising agencies and other service providers for advertisers, with whom we enter into ongoing 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 years ended December 31, 2019 and 2018:

•

•

our revenue was $661.1 million and $477.3 million, respectively, representing an increase of 39%; and

our net income was $108.3 million and $88.1 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.

38

 
 
 
 
 
In addition, we believe the markets outside of the U.S. offer an opportunity for growth, and 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.

Factors Affecting Our Performance

Growth in and Retention of Client Spend

Our recent growth has been driven by expanding our share of spend by our existing clients and adding new clients. Our clients include some of the
largest advertising agencies in the world, and we believe there is significant room for us to expand further within these clients. As a result, future revenue
growth depends upon our ability to retain our existing clients and to gain a larger amount of their advertising spend through our platform.

In order to analyze the contribution to the growth of our business driven by the increase in gross spend from existing clients, we measure annual gross
spend for the set of clients, or cohort, that commenced spending on our platform in a specific year relative to subsequent periods. The gross spend from each
of our cohorts has increased over subsequent periods. However, over time we will likely lose clients from each cohort, clients may spend less on our platform
and the growth rate of gross spend may change. Any such change could have a significant negative impact on gross spend and operating results.

Ability to Expand our Omnichannel Reach, Including CTV and Digital Radio

We enable the purchase of advertising inventory in a wide variety of formats, such as display, mobile, video, audio, social and native. Our future
growth will depend on our ability to maintain and grow the inventory of, and spend on, other channels in addition to display advertising. We believe that our
ability to integrate and offer CTV and digital radio advertising inventory for purchase through our platform, and in particular our ability to manage the
increased costs that will accompany these purchases, will impact the future growth of our business.

Growth of the Programmatic Advertising Market

Our operating results and prospects will be impacted by the overall adoption of programmatic advertising by inventory owners and content providers,

as well as advertisers and the agencies and service providers that represent them. Programmatic advertising has grown rapidly in recent years, and any
acceleration, or slowing, of this growth would affect our operating and financial performance. In addition, even if the programmatic advertising market
continues to grow at its current rate, our ability to position ourselves within the market will impact the future growth of our business.

Development of International Markets

We have been increasing our focus on markets outside the U.S. to serve the global needs of our clients. We believe that the global opportunity for

programmatic advertising is significant due to the growing middle class abroad, and should continue to expand as publishers and advertisers outside the U.S.
seek to adopt the benefits that programmatic advertising provides. To capitalize on this opportunity, we intend to continue investing in our presence
internationally. Our growth and the success of our initiatives in newer markets will depend on the continued adoption of our platform by our existing clients,
as well as new clients, in these markets. Information about geographic gross billings is set forth in Note 12—Segment and Geographic Information.

Seasonality

In the advertising industry, companies commonly experience seasonal fluctuations in revenue. For example, many advertisers allocate the largest
portion of their budgets to the fourth quarter of the calendar year in order to coincide with increased holiday purchasing. Historically, the fourth quarter of the
year reflects our highest level of advertising activity and the first quarter reflects the lowest level of such activity. We expect our revenue to continue to
fluctuate based on seasonal factors that affect the advertising industry as a whole.

Components of Our Results of Operations

We have one primary business activity and operate in one reportable and operating segment.

39

 
 
Revenue

We generate revenue from clients who enter into agreements with us to use our platform to purchase advertising inventory, data and other add-on

features.

We report revenue on a net basis which represents gross billings net of amounts we pay suppliers for the cost of advertising inventory, data and add-on
features. Our accounts receivable are recorded at the amount of gross billings to clients, net of allowances, for the amounts we are responsible to collect, and
our accounts payable are recorded at the amount payable to suppliers. Accordingly, both accounts receivable and accounts payable appear large in relation to
revenue reported on a net basis.

Revenue as a percentage of gross spend may fluctuate from period to period due to a number of factors, such as changes in the proportion of spend
represented by our larger clients with the lowest platform fees, our clients’ use of platform features and volume discounts. We expect that our revenue as a
percentage of gross spend will fluctuate in the future, especially as we introduce and as our clients select new platform features, expand our omnichannel
capabilities, extend our reach to more CTV inventory and add additional clients whose businesses may have different underlying business models.

Refer to “Critical Accounting Policies and Estimates—Revenue Recognition” below for a description of our revenue recognition policies.

Operating Expenses

We classify our operating expenses into the following four categories:

Platform Operations. Platform operations expense consists of expenses related to hosting our platform, which includes “internet traffic” associated

with the viewing of available impressions or queries per second (“QPS”) and providing support to our clients. Platform operations expense includes hosting
costs, personnel costs, and amortization of acquired technology and capitalized software costs for the development of our platform, including allocated
overhead. Personnel costs included in platform operations include salaries, bonuses, stock-based compensation, and employee benefit costs, and are primarily
attributable to personnel who provide our clients with support using our platform and the personnel who support our platform. We capitalize certain costs
associated with the development of our platform and amortize these costs in platform operations over their estimated useful lives. We allocate overhead such
as information technology infrastructure, rent and occupancy charges based on headcount.

We expect platform operations expenses to increase in absolute dollars in future periods as we continue to experience increased volumes of QPS

through our platform and hire additional personnel to support our clients.

Sales and Marketing. Sales and marketing expense consists primarily of personnel costs, including salaries, bonuses, stock-based compensation,

employee benefits costs and commission costs, for our sales and marketing personnel. Sales and marketing expense also includes costs for market
development programs, advertising, promotional and other marketing activities, and allocated overhead. We allocate overhead such as information technology
infrastructure, rent and occupancy charges based on headcount. Commissions costs are expensed as incurred.

Our sales organization focuses on marketing our platform to increase its adoption by existing and new clients. We are also focused on expanding our
international business by growing our sales teams in countries in which we currently operate, as well as establishing a presence in additional countries. As a
result, we expect sales and marketing expenses to increase in absolute dollars in future periods. Sales and marketing expense as a percentage of revenue may
fluctuate from period to period based on revenue levels and the timing of our investments in our sales and marketing functions as these investments may vary
in scope and scale over periods and are impacted by the revenue seasonality in our industry and business.

Technology and Development. Our technology and development expense consists primarily of personnel costs, including salaries, bonuses, stock-based

compensation and employee benefits costs, third-party consultant costs associated with the ongoing development and maintenance of our platform and
integrations with our advertising and data inventory suppliers, amortization of capitalized third-party software used in the development of our platform and
allocated overhead. We allocate overhead such as information technology infrastructure, rent and occupancy charges based on headcount. Technology and
development costs are expensed as incurred, except to the extent that such costs are associated with software development that qualifies for capitalization,
which are then recorded as capitalized software development costs included in other assets, non-current on our consolidated balance sheet. We amortize
capitalized software development costs relating to our platform to platform operations expense.

We believe that continued investment in our platform is critical to attaining our strategic objectives and long-term growth. We therefore expect

technology and development expense to increase 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 ramp up the volume of advertising spend on our platform. Our development efforts also
include additional platform functionality to support our international expansion. We also intend to invest in technology to further automate our business
processes.

General and Administrative. Our general and administrative expense consists primarily of personnel costs, including salaries, bonuses, stock-based

compensation, and employee benefits costs associated with our executive, finance, legal, human resources, compliance, and other administrative personnel, as
well as accounting and legal professional services fees, bad debt expense and allocated overhead. We allocate overhead such as information technology
infrastructure, rent and occupancy charges based on headcount.

We expect to continue to invest in corporate infrastructure to support growth. We expect general and administrative expenses to increase in absolute

dollars in future periods.

Other Expense (Income), Net

Interest Expense. Interest expense is mainly related to our debt, which carries a variable interest rate.

Interest Income. Interest income is mainly related to our cash, cash equivalents and short-term investments, which carry variable interest rates.

Foreign Currency Exchange Loss, Net. Foreign currency exchange loss, net consists primarily of gains and losses on foreign currency transactions. We
have foreign currency exposure related to our accounts receivable and, to a much lesser extent, accounts payable that are denominated in currencies other than
the U.S. Dollar, principally the Euro, British Pound, Australian Dollar, Canadian Dollar, Indonesian Rupiah, Japanese Yen, Singapore Dollar and Thai Baht.

Provision for Income Taxes

The provision for income taxes consists primarily of U.S. federal, state, and foreign income taxes. Our income tax provision may be significantly
affected by changes to our estimates for tax in jurisdictions in which we operate and other estimates utilized in determining the global effective tax rate.
Actual results may also differ from our estimates based on changes in economic conditions. Such changes could have a substantial impact on the income tax
provision. We evaluate the judgments surrounding our estimates and make adjustments, as appropriate, each reporting period.

Our effective tax rate differs from the U.S. federal statutory income tax rate due to stock-based compensation, foreign tax rate differences, research

and development tax credits, and state taxes.

Realization of our deferred tax assets is dependent primarily on the generation of future taxable income. In considering the need for a valuation

allowance, we consider our historical, as well as future, projected taxable income along with other objectively verifiable evidence. Objectively verifiable
evidence includes our realization of tax attributes, assessment of tax credits and utilization of net operating loss carryforwards during the year.

The increase in revenue was primarily due to an increase in gross spend on our platform. Gross spend on our platform by existing clients added prior
to 2019 increased by 24% in the aggregate in 2019, and these existing clients represented approximately 92% of the total gross spend in 2019. In 2019, 58%
of existing clients added prior to 2019 increased their gross spend on our platform and their average increase in gross spend was approximately $2.6 million.

Revenue as a percentage of gross spend in the aggregate may fluctuate from period to period based on our client mix and the extent to which clients

utilize our platform’s features.

The increase in platform operations expense was primarily due to increases of $19.3 million in hosting costs and $13.8 million in personnel costs,

including $0.9 million of stock-based compensation and $6.0 million in allocated facilities. The increase in hosting costs was primarily attributable to
supporting the increased use of our platform by our clients. The increase in personnel costs was primarily due to an increase in headcount for our client
support team. The increase in allocated facilities costs was primarily driven by new office leases to support our growth.

We expect platform operations expenses to increase in absolute dollars in future periods, as we continue to experience increased volumes of

transactions through our platform and hire additional personnel to support our clients.

The increase in sales and marketing expense was primarily due to increases of $32.6 million in personnel costs, including $9.5 million of stock-based

compensation, $5.1 million in marketing expenses and $8.1 million in allocated facilities costs. The increase in personnel costs was primarily due to an
increase in sales and marketing headcount in order to support our sales efforts and to continue to develop and maintain relationships with our clients. The
increase in overall marketing expenses was mainly related to our participation in industry events, tradeshows and related public relations activities. The
increase in allocated facilities costs was primarily driven by new office leases to support our growth.

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

The difference between the effective tax rate in 2019 of 7% and the U.S. federal statutory income tax rate of 21% was primarily due to the impact of

tax benefits associated with stock-based awards partially offset by the impact of taxes in foreign jurisdictions. For 2019, the provision for income taxes
included $43.1 million of benefits associated with stock-based awards.

The difference between the effective tax rate in 2018 of 17% and the U.S. federal statutory income tax rate of 21% was primarily due to the impact of
tax benefits associated with stock-based awards partially offset by the impact of state taxes. For 2018, the provision for income taxes included $15.1 million
of benefits associated with stock-based awards.

Quarterly Results of Operations

The following tables set forth our quarterly unaudited consolidated statements of operations data in dollars and as a percentage of total revenue for

each of the eight quarters in the period ended December 31, 2019. We have prepared the quarterly unaudited consolidated statements of operations data on a
basis consistent with the audited consolidated financial statements included in “Item 8. Financial Statements and Supplementary Data” of this Annual Report

Liquidity and Capital Resources

As of December 31, 2019, we had cash and cash equivalents of $130.9 million, including cash of $29.8 million held by our international subsidiaries,

short-term investments in marketable securities of $124.1 million and working capital of $518.8 million.

We believe our existing cash and cash equivalents, cash flow from operations, and our undrawn available balance under our amended credit facility

(refer to the section captioned “Credit Facility” below) will be sufficient to meet our working capital requirements for at least the next 12 months. Our current
credit facility matures in May 2022. Further, in November 2017, we filed a shelf registration statement on Form S-3 with the SEC, or 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 Annual
Report on Form 10-K.

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.

Credit Facility

On October 26, 2018, we and a syndicate of banks, led by Citibank, N.A., as agent, entered into the Second Amended and Restated Loan and Security

Agreement (the “Second A&R Credit Agreement”, which we also refer to as “our credit facility”). Available funding commitments to us under the Second
A&R Credit Agreement, subject to certain conditions, total up to $150.0 million, 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 Second A&R Credit Facility by an amount not to
exceed $100.0 million. As of December 31, 2019, we did not have an outstanding debt balance under the Second A&R Credit Facility, and availability was
$143.3 million. We were in compliance with all covenants as of December 31, 2019.

For additional information regarding the Second A&R Credit Agreement, refer to Note 7—Debt.

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.

In 2019, cash provided by operating activities of $60.2 million resulted primarily from net income adjusted for non-cash items of $222.9 million,
partially offset by a net decrease in our working capital of $162.7 million. The net decrease in working capital was primarily related to an increase in accounts
receivable of $331.4 million, partially offset by an increase in accounts payable of $191.8 million. The increase in accounts receivable was primarily due to
the increase in spend through our platform and the timing of cash receipts from clients and the increase in accounts payable was primarily due to the timing of
payments to suppliers.

In 2018, cash provided by operating activities of $86.6 million resulted primarily from net income adjusted for non-cash items of $142.1 million,
partially offset by a net decrease in our working capital of $55.5 million. The net decrease in working capital was primarily related to an increase in accounts
receivable of $239.9 million, partially offset by an increase in accounts payable of $177.7 million. The increase in accounts receivable was primarily due to
the increase in spend through our platform and the timing of cash receipts from clients and the increase in accounts payable was primarily due to the timing of
payments to suppliers.

Investing Activities

Our primary investing activities consist of investing in short-term investments in marketable securities, purchases of property and equipment 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.

In 2019, we used $163.8 million of cash in investing activities, consisting of $212.8 million to purchase short-term investments, $35.7 million to

purchase property and equipment and $4.9 million of investments in capitalized software, partially offset by maturities of short-term investments of $89.5
million. Purchases of property and equipment, leasehold improvements and investments in capitalized software support our growth and further development
of our platform.

In 2018, we used $25.2 million of cash in investing activities, consisting of $19.8 million to purchase property and equipment and $5.4 million of

investments in capitalized software.

Financing Activities

Our financing activities consisted primarily of proceeds from our equity compensation plans, taxes paid related to net settlement of restricted stock

awards and borrowings and repayments of our debt.

In 2019, cash provided by financing activities of $27.3 million was primarily due to the $29.9 million proceeds from stock option exercises and $16.7

million proceeds from the employee stock purchase plan, partially offset by $19.3 million of taxes paid for restricted stock award settlements.

In 2018, cash used in financing activities of $10.1 million was primarily due to the $27.0 million repayment of our line of credit and taxes paid related

to net settlement of restricted stock of $6.7 million, partially offset by proceeds of $13.8 million from our employee stock purchase plan and $10.0 million
from stock options exercises.

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 as of December 31, 2019 other than operating leases and the indemnification agreements described in Note 13
—Commitments and Contingencies.

Contractual Obligations and Known Future Cash Requirements

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.

As of December 31, 2019, our total amount of gross unrecognized tax benefits was $53.2 million before netting with deferred tax assets for tax credit

carryforwards and is considered a long-term obligation. Due to their nature, there is a high degree of uncertainty regarding the time of future cash outflows
and other events that extinguish these liabilities.

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. No demands have been made upon us to provide indemnification under such agreements and there are no claims
that we are aware of that could have a material effect on our consolidated financial statements.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America

(“GAAP”). The preparation of these 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, operating lease assets and liabilities, including our incremental borrowing rate and terms and
provisions of each lease, 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. Except for the changes described in Note 2—Basis of Presentation and
Summary of Significant Accounting Policies, there were no other changes to our critical accounting policies and estimates.

Revenue Recognition

We generate revenue from clients who enter into agreements with us to use our platform to purchase advertising inventory, data and other add-on

features. We charge our clients a platform fee, which is a percentage of a client’s purchases through the platform. In addition, we invoice our clients for the
cost of advertising inventory purchased, plus data and any add-on features purchased through the platform.

We determine revenue recognition through the following steps:

•

•

•

•

•

Identification of a contract with a customer;

Identification of the performance obligations in the contract;

Determination of the transaction price;

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

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

We maintain agreements with each client and supplier in the form of MSAs, which set out the terms of the relationship and access to our platform. Our

performance obligation is to provide the use of our platform to clients to develop ad campaigns and select the advertising inventory, data and other add-on
features. We charge clients a platform fee, based on a percentage of a client’s purchases through the platform, and the transaction price is determined based on
the consideration to which we expect to be entitled in exchange for the completion of a transaction, that is, when a bid is won. The platform fee percentage is
based on the level of purchases by the client through the platform during the month. We recognize revenue for our platform fee at a point in time when a
purchase by the client occurs through our platform, which is when a bid is won. Subsequent to a bid being won through our platform, the associated fees are
generally not subject to adjustment or refund. Historically, any refunds and adjustments have not been material.

We report revenue net of amounts we pay suppliers for the cost of advertising inventory, third-party data and other add-on features (collectively,
“Supplier Features”). The determination of whether we are the principal or agent, and hence whether to report revenue on a gross basis for the amount of the
Supplier Features the clients purchase using the platform plus our platform fees or on a net basis for the amount of platform fees charged to the client,
requires judgment. We determined that we are not primarily responsible for the purchase of Supplier Features, but rather, we are primarily responsible to
provide a platform that enables clients to bid on advertising inventory, and use data and other add-on features in designing and executing their campaigns. We
do not control the Supplier Features prior to the purchase by the client, and we do not have pricing latitude with respect to the cost of such features. The
platform fee we charge clients is a percentage of their purchases through our platform, similar to a commission, and the platform fee is not contingent on the
results of an advertising campaign. Based on these and other factors, we determined that we are not the principal in the purchase and sale of Supplier Features
in all of our arrangements, and therefore, we report revenue on a net basis for the platform fees charged to clients.

Stock-Based Compensation

Compensation expense related to stock options, restricted stock awards and units, which we refer to, collectively, as restricted stock, and awards
granted under our employee stock purchase plan, or ESPP, is measured and recognized in our consolidated financial statements based on the fair value of the
awards granted. The increase in our stock price since our IPO in September 2016 and our growth in headcount have resulted in increased stock-based
compensation for each sequential fiscal year since our IPO. The fair value of each option award is estimated on the grant date using the Black-Scholes option-
pricing model. The fair value of restricted stock is calculated using the closing market price of our common stock on the date of grant, and for performance-
based restricted stock, we also assess the probability of targets being achieved in determining the amount of expense to recognize. Stock-based compensation
expense related to stock options and restricted stock is recognized on a straight-line basis over the requisite service periods of the awards, which is generally
four years. For performance-based restricted stock, expense is recognized on a graded-vesting attribution basis over the requisite service period of the award
and is adjusted in subsequent reporting periods if the assessed probability or estimated level of achievement of the performance goals changes. Stock-based
compensation expense for ESPP awards is recognized on a graded-vesting attribution basis over the requisite service period of each award.

For additional information regarding stock-based compensation and the assumptions used for determining the fair value of stock options and ESPP

awards, refer to Note 2—Basis of Presentation and Summary of Significant Accounting Policies and Note 10—Stock-Based Compensation.

Income Taxes

Our income tax provision may be significantly affected by changes to our estimates for tax in jurisdictions in which we operate and other estimates

utilized in determining the global effective tax rate. Actual results may also differ from our estimate based on changes in economic conditions. Such changes
could have a substantial impact on the income tax provision. We evaluate the judgments surrounding our estimates and make adjustments, as appropriate,
each reporting period.

Deferred income tax assets and liabilities are determined based upon the net effects of the differences between the consolidated financial statements

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

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

In April 2019, we completed a series of transactions resulting in changes to its international legal structure, including a transfer of certain intellectual
property rights among wholly owned subsidiaries, primarily to align its structure to its evolving operations. We recorded a $262.4 million deferred tax asset
associated with this restructuring offset by a reserve for uncertain tax position of $51.0 million. Based on available objective evidence, management believes
it is not more-likely-than-not that these additional foreign deferred tax assets will be realizable as of December 31, 2019 and, therefore, are offset by a full
valuation allowance to the extent not offset by reserves from uncertain tax positions. Management applied significant judgment in estimating the fair value of
intangible assets, which involved the use of significant assumptions, including revenue growth rates, margins and discount rates. 

Leases

We have operating leases for our offices. We recognize most of our operating lease rights and commitments as operating lease right-of-use assets

(“operating lease assets”), operating lease liabilities and operating lease liabilities, non-current, respectively, on our consolidated balance sheets.

We determine if an arrangement is, or contains, a lease at inception. Operating lease assets and liabilities are initially recorded based on the present

value of lease payments over the lease term, which includes the minimum unconditional term of the lease, and may include options to extend or terminate the
lease when it is reasonably certain at the commencement date that such options will be exercised. The decision to include these options involves consideration
of our overall growth plans, as well as other strategic and economic factors. Since determination of the lease term requires an application of judgment, lease
terms that differ from our determination could potentially have a material impact on our consolidated balance sheet. As the rate implicit for each of our leases
is not readily determinable, we use our incremental borrowing rate, based on the information available at the lease commencement date in determining the
present value of our expected lease payments. The rate is determined by analyzing and combining an applicable risk-free rate, a financial spread adjustment
and any lease specific adjustment, which requires judgment.

Item 7A. Quantitative and Qualitative Disclosure about Market Risk

We have operations both within the U.S. and internationally, and we are exposed to market risks in the ordinary course of our business. These risks

include primarily interest rate, foreign currency exchange and inflation 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. No amount was owed on our revolving credit facility as of December 31, 2019.

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, Indonesian Rupiah, Japanese Yen, Singapore Dollar and Thai Baht. 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 translating 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 December 31, 2019, would
result in a foreign currency loss of approximately $18.5 million. In the event our non-U.S. Dollar denominated sales and expenses increase, our operating
results 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.

Inflation Risk

We do not believe that inflation has had a material effect on our business, financial condition or results of operations. If our costs were to become
subject to significant inflationary pressures, we might not be able to fully offset such higher costs through price increases. Our inability or failure to do so
could harm our business, financial condition and results of operations.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of The Trade Desk, Inc. and its subsidiaries (the “Company”) as of December 31, 2019 and
2018, and the related consolidated statements of operations, of stockholders’ equity and of cash flows for each of the three years in the period ended
December 31, 2019, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's
internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by
the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of
December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019 in
conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material
respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework
(2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinions

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

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

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

Definition and Limitations of Internal Control over Financial Reporting

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

52

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

Critical Audit Matters

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

Revenue Recognition – Platform Fees

As described in Note 2 to the consolidated financial statements, the Company maintains agreements with each client and supplier in the form of master
service agreements, which set out the terms of the relationship and access to the Company’s platform.  The Company’s performance obligation is to provide
the use of its platform to clients to develop ad campaigns and select the advertising inventory, data and other add-on features. The Company charges clients a
platform fee, based on a percentage of a client’s purchases through the platform. The Company recognizes revenue for its platform fee at a point in time when
the purchase by a client occurs through its platform. Management reports revenue on a net basis for the platform fees charged to clients. For the year ended
December 31, 2019, the Company’s revenue was $661 million.  

The principal considerations for our determination that performing procedures relating to revenue recognition – platform fees is a critical audit matter are the
significant audit effort required in performing audit procedures and in evaluating audit evidence relating to client purchases through the Company’s platform
to recognize revenue.  

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated
financial statements. These procedures included testing the effectiveness of controls relating to the completeness and accuracy of the revenue recognized for
platform fees charged to clients, including both manual and automated controls operating over the information generated from the Company’s platform and
controls over the accuracy in calculating revenue invoices based on client purchases. These procedures also included, among others, evaluating the
completeness, accuracy, and relevance of underlying information generated from the Company’s platform by inspecting a sample of master service
agreements and contracts for selected clients and evaluating the appropriateness of the revenue recognized by recalculating platform fees due and validating
related cash receipts.

Intellectual Property Restructuring Transaction

As described in Note 11 to the consolidated financial statements, in April 2019, the Company initiated a transaction to transfer certain intellectual property
rights among wholly owned subsidiaries, primarily to align its structure to its evolving operations. The transaction resulted in an increase in foreign deferred
tax assets in an amount of $262.4 million. Management applied significant judgment in estimating the fair value of intangible assets, which involved the use
of significant assumptions, including revenue growth rates, margins and discount rates.  

The principal considerations for our determination that performing procedures relating to the intellectual property restructuring transaction is a critical audit
matter are that there was a significant amount of judgment by management when developing the estimate of the fair value of intellectual property rights which
in turn led to a high degree of auditor judgment and subjectivity in applying procedures to evaluate the fair value of intellectual property rights. Significant
audit effort was required in evaluating the significant assumptions related to the fair value of the intellectual property rights, including the revenue growth
rates, margins and discount rates, and the audit effort involved the use of professionals with specialized skill and knowledge.  

53

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated
financial statements. These procedures included testing the effectiveness of controls over management’s valuation of intellectual property rights, including
controls over the development of the revenue growth rates, margins, and discount rate assumptions. These procedures also included, among others, reading
the intellectual property license agreement and cost sharing agreement; testing management’s process for estimating the fair value of intellectual property
rights, which included evaluating the appropriateness of the methodology used and evaluating the reasonableness of management’s significant assumptions.
Procedures were also performed to test the completeness, accuracy, and relevance of underlying data provided by management. Evaluating the reasonableness
of the revenue growth rates and margin assumptions involved considering current and past performance of the business and evaluating the accuracy of
management’s historical forecasting. Evaluating the reasonableness of the revenue growth rates also involved assessing consistency with external market and
industry data. The discount rates were evaluated by considering the cost of capital of comparable businesses and other industry factors.  Professionals with
specialized skill and knowledge were used to assist in the evaluation of certain significant assumptions, including the discount rates.

THE TRADE DESK, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 (CTV).

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

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of

America (“GAAP”) and include the operations of the Company and its wholly owned subsidiaries. All intercompany transactions have been eliminated in
consolidation. The Company has no material components of other comprehensive income (loss), and accordingly, the Company’s comprehensive income is
the same as its net income for all periods presented.

Except for the accounting policy for leases that was updated as a result of adopting Financial Accounting Standards Board ("FASB") Accounting
Standards Update ("ASU") No. 2016-02, Leases, as amended ("ASU 2016-02"), our significant accounting policies have been applied consistently to all years
presented. Refer to “Operating Leases” below.

Use of Estimates

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

On an on-going basis, management evaluates its estimates, primarily those related to: (1) revenue recognition criteria, including the determination of
revenue reporting as net versus gross in the Company’s revenue arrangements, (2) allowances for doubtful accounts, (3) operating lease assets and liabilities,
including our incremental borrowing rate and terms and provisions of each lease (4) the useful lives of property and equipment and capitalized software
development costs, (5) income taxes, (6) assumptions used in the Black-Scholes option pricing model to determine the fair value of stock-based
compensation, (7) the recognition and disclosure of contingent liabilities and (8) the assumptions used in valuing acquired assets and assumed liabilities in
business combinations. These estimates are based on historical data and experience, as well as, various other factors that management believes to be
reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not
readily apparent from other sources.

Revenue Recognition

On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606),

using the modified retrospective method. The adoption of ASU 2014-09 did not result in a change in the timing or amount of revenue recognized.

The Company determines revenue recognition through the following steps:

•

•

•

•

•

Identification of a contract with a customer;

Identification of the performance obligations in the contract;

Determination of the transaction price;

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

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

The Company maintains agreements with each client and supplier in the form of master service agreements, which set out the terms of the relationship

and access to the Company’s platform. The Company’s performance obligation is to provide the use of its platform to clients to develop ad campaigns and
select the advertising inventory, data and other add-on features. The Company charges clients a platform fee, based on a percentage of a client’s purchases
through the platform, and the transaction price is determined based on the consideration to which it expects to be entitled in exchange for the completion of a
transaction, that is, when a bid is won. The platform fee percentage is based on the level of purchases by the client through the platform during the month.
The Company recognizes revenue for its platform fee at a point in time when a purchase by the client occurs through its platform, which is when a bid is won.
Subsequent to a bid being won through the Company’s platform, the associated fees are generally not subject to refund or adjustment. Historically, any
refunds and adjustments have not been material.

59

 
 
 
 
 
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 determination of whether the Company is the principal or agent, and hence whether to report revenue on a gross basis
for the amount of the Supplier Features the clients purchase using the platform plus the Company’s platform fees or on a net basis for the amount of platform
fees charged to the client, requires judgment. The Company determined that it is not primarily responsible for the purchase of Supplier Features, but rather, it
is primarily responsible to provide a platform that enables clients to bid on advertising inventory, and use data and other add-on features in designing and
executing their campaigns. The Company does not control the Supplier Features prior to the purchase by the client, and it does not have pricing latitude with
respect to the cost of such features. The platform fee the Company charges clients is a percentage of their purchases through its platform, similar to a
commission, and the platform fee is not contingent on the results of an advertising campaign. Based on these and other factors, the Company determined that
it is not the principal in the purchase and sale of Supplier Features in all of its arrangements, and therefore, it reports revenue on a net basis for the platform
fees charged to clients.

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”). Some of the Company’s clients have payment relationships directly with advertising inventory suppliers in which case the
Company only bills these clients for third-party data, other add-on features and its platform fees. The Company invoices its clients on a monthly basis for the
purchases occurring during the month. Invoice payment terms, negotiated on a client-by-client basis, are typically between 30 to 90 days. However, for
certain agency clients with sequential liability terms, payments are not due to the Company until such agency client has received payment from its clients who
are advertisers. 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.

Refer to Note 12 for geographic information related to Gross Billings.

Operating Expenses

The Company classifies its operating expenses into four categories:

Platform Operations. Platform operations expense consists of expenses related to hosting the Company’s platform, which includes “internet traffic”
associated with the viewing of available impressions or queries per second (“QPS”) and providing support to clients. Platform operations expense includes
hosting costs, personnel costs, and amortization of acquired technology and capitalized software costs for the development of the Company’s platform,
including allocated overhead. Personnel costs included in platform operations include salaries, bonuses, stock-based compensation, and employee benefit
costs, and are primarily attributable to personnel who provide the Company’s clients with support using the Company’s platform and the personnel who
support the Company’s platform. The Company capitalizes certain costs associated with the development of the Company’s platform and amortizes these
costs over their estimated useful lives in platform operations expense. The Company allocates overhead such as information technology infrastructure, rent
and occupancy charges based on headcount.

Sales and Marketing. Sales and marketing expense consists primarily of personnel costs, including salaries, bonuses, stock-based compensation,
employee benefits costs and commission costs, for the Company’s sales and marketing personnel. Sales and marketing expense also includes costs for market
development programs, advertising, promotional and other marketing activities, and allocated overhead. The Company allocates overhead such as information
technology infrastructure, rent and occupancy charges based on headcount. Commissions costs are expensed as incurred.

Technology and Development. The Company’s technology and development expense consists primarily of personnel costs, including salaries, bonuses,

stock-based compensation and employee benefits costs, third-party consultant costs associated with the ongoing development and maintenance of the
Company’s platform and integrations with our advertising and data inventory suppliers, amortization of capitalized third-party software used in the
development of the Company’s platform and allocated overhead. The Company allocates overhead such as information technology infrastructure, rent and
occupancy charges based on headcount. Technology and development costs are expensed as incurred, except to the extent that such costs are associated with
software development that qualifies for capitalization, which are then recorded as capitalized software development costs included in other assets, non-current
on the Company’s consolidated balance sheet. The Company amortizes capitalized software development costs relating to the Company’s platform to
platform operations expense.

General and Administrative. The Company’s general and administrative expense consists primarily of personnel costs, including salaries, bonuses,
stock-based compensation, and employee benefits costs associated with the Company’s executive, finance, legal, human resources, compliance, and other
administrative personnel, as well as accounting and legal professional services fees, bad debt expense and allocated overhead. The Company allocates
overhead such as information technology infrastructure, rent and occupancy charges based on headcount.

60

Stock-Based Compensation

Compensation expense related to stock options, restricted stock awards and units, which are referred to collectively as restricted stock, and awards

granted under the Company’s employee stock purchase plan (“ESPP”), is measured and recognized in the consolidated financial statements based on the fair
value of the awards granted. The fair value of each option award is estimated on the grant date using the Black-Scholes option-pricing model. The fair value
of restricted stock is calculated using the closing market price of the Company’s common stock on the date of grant, and for performance-based restricted
stock, we also assess the probability of targets being achieved in determining the amount of expense to recognize. Stock-based compensation expense related
to stock options and restricted stock is recognized on a straight-line basis over the requisite service periods of the awards, which is generally four years. For
performance-based restricted stock, expense is recognized on a graded-vesting attribution basis over the requisite service period of the award and is adjusted
in subsequent reporting periods if the assessed probability or estimated level of achievement of the performance goals changes. Stock-based compensation
expense for ESPP awards is recognized on a graded-vesting attribution basis over the requisite service period of each award.

Determining the fair value of stock options and ESPP awards requires judgment. The Company’s use of the Black-Scholes option pricing model

requires the input of subjective assumptions. The assumptions used in the Company’s option-pricing model represent management’s best estimates. These
estimates involve inherent uncertainties and the application of management’s judgment.

These assumptions and estimates are as follows:

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

the awards.

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

Volatility. Because the Company has a short trading history for its common stock, the Company determines the price volatility based on a blend of the
historical volatilities of a publicly traded peer group, implied volatilities from its traded options, and its historical volatility, based on daily price observations
over a period equivalent to the expected term of the award.

Dividend Yield. The dividend yield assumption is based on the Company’s history and current expectations of dividend payouts. The Company has

never declared or paid any cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future, so the Company
used an expected dividend yield of zero.

The Company will continue to use judgment in evaluating the assumptions related to the Company’s stock-based compensation.

Income Taxes

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

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

In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income ("GILTI") provisions of the Tax

Cuts and Jobs Act (the "Act"). The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations.
The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or to treat any taxes on GILTI inclusions as period cost are both
acceptable methods subject to an accounting policy election. The Company elected to treat any GILTI inclusions as a period cost.

61

Net Income Per Share Attributable to Common Stockholders

Basic net income per share attributable to common stockholders is calculated by dividing the net income attributable to common stockholders by the

weighted-average number of shares of common stock outstanding.

Diluted net income per share attributable to common stockholders adjusts the basic net income per share attributable to common stockholders and the

weighted-average number of shares of common stock outstanding for the potentially dilutive impact of stock options, restricted stock and ESPP using the
treasury-stock method.

Cash, Cash Equivalents and Marketable Securities

The Company considers all short-term highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash
equivalents, consisting of money market funds and time deposits, are carried at fair value. Refer to Note 6—Cash, Cash Equivalents and Short-Term
Investments for additional information regarding the fair value of cash equivalents and marketable securities.

The Company classifies its marketable securities as available-for-sale investments in its current assets because they represent investments of cash

available for current operations. Available-for-sale investments are carried at fair value with any unrealized gains and losses, net of taxes, included in
accumulated other comprehensive income (loss) in stockholders' equity. Unrealized losses are charged against other expense when a decline in fair value is
determined to be other-than-temporary. The Company determines realized gains or losses on sale of marketable securities on a specific identification method,
and records such gains or losses as other expense (income).

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount, are unsecured and do not bear interest. The Company performs ongoing credit evaluations of

its clients and certain advertisers when the Company’s agreements with its clients contain sequential liability terms that provide that the client payments are
not due to the Company until the client has received payment from its clients who are advertisers. The allowance for doubtful accounts is based on the best
estimate of the amount of probable credit losses in existing accounts receivable. The allowance for doubtful accounts is determined based on historical
collection experience and the review in each period of the status of the then-outstanding accounts receivable, while taking into consideration current client
information, subsequent collection history and other relevant data. The Company reviews the allowance for doubtful accounts on a quarterly basis. Account
balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.

The following table presents changes in the allowance for doubtful accounts (in thousands):

Property and equipment are recorded at historical cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-

line method based upon the following estimated useful lives:

Computer equipment
Purchased software
Furniture, fixtures and office equipment
Leasehold improvements

Years
2 – 3
3 – 5

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

Repair and maintenance costs are charged to expense as incurred, while renewals and improvements are capitalized. When assets are retired or

otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the
Company’s operating results.

Capitalized Software Development Costs

The Company capitalizes certain costs associated with creating and enhancing internally developed software related to the Company’s technology

infrastructure. These costs include personnel and related employee benefits expenses for employees who are directly associated with and who devote time to
software development projects, and external direct costs of materials and services consumed in developing or obtaining the software. Software development
costs that do not qualify for capitalization, as further discussed below, are expensed as incurred and recorded in technology and development expenses in the
consolidated statements of operations.

Software development activities typically consist of three stages: (1) the planning phase; (2) the application and infrastructure development stage; and

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

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

Cloud computing arrangements (“CCAs”), such as software as a service and other hosting arrangements, are evaluated for capitalized implementation
costs in a similar manner as capitalized software development costs. If a CCA includes a software license, the software license element of the arrangement is
accounted for in a manner consistent with the acquisition of other software licenses. If a CCA does not include a software license, the service element of the
arrangement is accounted for as a service contract. The Company capitalized certain implementation costs for its CCAs that are service contracts, which are
included in other assets, non-current. The Company amortizes capitalized implementation costs in a CCA over the life of the service contract. The Company
capitalized $2.9 million and $0.9 million of CCA implementation costs in 2019 and 2018, respectively. Amortization expense was $0.6 million and
$0.1 million for 2019 and 2018, respectively.

Business Combinations

The results of a business acquired in a business combination are included in the Company’s consolidated financial statements from the date of the

acquisition. Purchase accounting results in assets and liabilities of an acquired business generally being recorded at their estimated fair values on the
acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill.

Transaction costs associated with business combinations are expensed as incurred and are included in general and administrative expenses in the

consolidated statements of operations.

The Company performs valuations of assets acquired and liabilities assumed and allocates the purchase price to its respective assets and liabilities.

Determining the fair value of assets acquired and liabilities assumed 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 the assistance of valuation specialists in concluding on fair value measurements in connection with determining fair values of assets acquired and
liabilities assumed in a business combination.

In October 2017, the Company paid $3.0 million in cash for certain assets of a data company accounted for as a business combination. These assets

primarily consisted of acquired technology and goodwill which are included in other assets, non-current.

Operating Leases

On January 1, 2019, the Company adopted ASU No. 2016-02, codified as Accounting Standards Codification (“ASC”) 842, using the modified
retrospective adoption approach. The Company elected the transition option provided by ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, to
not restate comparative periods, but rather to initially adopt the requirements of ASC 842 on January 1, 2019. The most significant impact of the adoption of
ASC 842 resulted in the recognition of operating lease right-of-use assets (“operating lease assets’) of approximately $41 million, net of deferred rent and
direct costs, and operating lease liabilities of approximately $47 million on its consolidated balance sheet. The impact on the Company’s consolidated
statements of income and cash flows was not material.

63

 
ASC 842, provides various optional transition practical expedients. Upon transition to ASC 842, the Company elected the use of the package of
practical expedients to not reassess: whether a contract is or contains a lease, lease classification and indirect costs. The Company did not elect the hindsight
practical expedient in transition. The Company has elected to not separate lease and non-lease components.

Operating lease assets represent the Company’s right to control the use of an identified asset for a period of time, or term, in exchange for

consideration, and operating lease liabilities represent its obligation to make lease payments arising from the aforementioned right.

The Company determines if an arrangement is, or contains, a lease at inception. Operating leases are included in operating lease assets, operating lease
liabilities and operating lease liabilities, non-current on our consolidated balance sheets for all leases except for short-term leases with a term of 12 months or
less. Operating lease assets and liabilities are initially recorded based on the present value of lease payments over the lease term, which includes the minimum
unconditional term of the lease, and may include options to extend or terminate the lease when it is reasonably certain at the commencement date that such
options will be exercised. As the rate implicit for each of the Company’s leases is not readily determinable, the Company uses its incremental borrowing rate,
based on the information available at the lease commencement date in determining the present value of its expected lease payments. Operating lease assets
also include any initial direct costs and any lease payments made prior to the lease commencement date and are reduced by any lease incentives received.
Operating lease assets are amortized on a straight-line basis as the operating lease cost over the lease term on the consolidated statements of income. The
related amortization, referred to as noncash lease expense, along with the change in the operating lease liabilities are separately presented within the cash
flows from operating activities on the consolidated statements of cash flows.

Refer to Note 8—Leases for additional information.

Fair Value of Financial Instruments

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most

advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to
measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value measurements are based on a fair
value hierarchy, based on three levels of inputs, of which the first two are considered observable and the last unobservable, which are the following:

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

measurement date.

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

as quoted market prices for similar assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be
corroborated by observable market data for substantially the full term of the asset or liability.

Level 3—Unobservable inputs.

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

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

Certain long-lived assets including capitalized software development costs are also subject to measurement at fair value on a non-recurring basis if

they are deemed to be impaired as a result of an impairment review. To date, no material impairments have been recorded on those assets. 

64

Concentration of Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents, marketable

securities and accounts receivable. The Company maintains its cash and cash equivalents with financial institutions and its cash levels exceed the Federal
Deposit Insurance Corporation (FDIC) federally insured limits. Marketable securities and short-term investments consist of investments in U.S. government
securities, U.S. government agency securities, and high credit quality corporate debt securities.

For 2019, two clients accounted for 13% and 10%, respectively, of Gross Billings. For 2018, two clients accounted for 20% and 10%, respectively, of

Gross Billings. For 2017, three clients accounted for 22%, 11% and 10%, respectively, of Gross Billings.

As of December 31, 2019, three clients accounted for 18%, 16% and 16%, respectively, of consolidated accounts receivable. As of December 31,

2018, two clients accounted for 24% and 14%, respectively, of consolidated accounts receivable.

As of December 31, 2019 and 2018, no suppliers accounted for more than 10% of consolidated accounts payable.

Foreign Currency Transactions and Translation

The Company has entities operating in various countries. Each of these entities’ functional currency is the U.S. Dollar. Transactions in foreign

currencies are translated into U.S. Dollars at the rates of exchange in effect at the date of the transaction. Net transaction losses were approximately
$0.7 million, $1.9 million, and $4.0 million for the years ended December 31, 2019, 2018 and 2017, respectively, and are included in foreign currency
exchange loss, net in the accompanying consolidated statements of operations.

The Company enters into forward contracts to hedge foreign currency exposures related primarily to the Company’s foreign currency denominated

accounts receivable. The Company does not designate the foreign exchange forward contracts as hedges for accounting purposes and changes in the fair value
of the foreign exchange forward contracts are recorded in foreign currency exchange loss, net in the accompanying consolidated statements of operations. As
of December 31, 2019 and 2018, the Company had open forward contracts with aggregate notional amounts of $92.9 million and $78.8 million, respectively.
The fair value of the open forward contracts was not material. The Company’s forward contracts generally have terms of 30-60 days.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial

Instruments, which is intended to provide more decision-useful information about expected credit losses on financial instruments and other commitments to
extend credit held by a reporting entity at each reporting date. ASU 2016-13 revises the impairment model to utilize an expected loss methodology in place of
the currently used incurred loss methodology, which will result in more timely recognition of losses on financial instruments, including, but not limited to,
available for sale debt securities and accounts receivable. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326,
Financial Instruments - Credit Losses, and in April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments
– Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. These ASUs provide supplemental guidance and clarification to
ASU 2016-13 and must be adopted concurrently with the adoption of ASU 2016-13, cumulatively referred to as “Topic 326.” Topic 326 is effective for
annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. The Company is currently evaluating the
impact of this guidance on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement-Disclosure Framework (Topic 820). The updated guidance modifies the

disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. This guidance is effective for annual reporting
periods beginning after December 15, 2019, including interim periods within that reporting period. Early adoption is permitted for any removed or modified
disclosures. The Company is currently assessing the timing and impact of adopting the updated provisions.

In December 2019, the FASB issued Accounting Standard Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income
Taxes (ASU 2019-12), which simplifies the accounting for income taxes. This guidance will be effective for us in the first quarter of 2021 on a prospective
basis, and early adoption is permitted. The Company is currently evaluating the impact of the new guidance on our consolidated financial statements.

On October 26, 2018, the Company and a syndicate of banks, led by Citibank, N.A., as agent, entered into a second amended and restated loan and

security agreement (the “Second A&R Credit Agreement”). The Second A&R Credit Agreement amends and restates the Company’s existing credit facility
previously entered into on May 9, 2017, and consists of a $150.0 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 (the “Second A&R Credit Facility”). Under certain circumstances, the Company has the right to
increase the Second A&R Credit Facility by an amount not to exceed $100.0 million. The Second A&R Credit Agreement 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 Second A&R 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 a LIBOR rate, plus an applicable margin (“Base Rate Borrowings” and “LIBOR Rate Borrowings”). The Base Rate is defined as a
fluctuating interest rate equal to the greatest of (1) the federal funds rate plus 0.50%, (2) Citibank, N.A.’s prime rate, and (3) one month LIBOR rate plus
2.00%. 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 Second A&R Credit Facility ranges, based on the applicable
leverage, from 0.225% to 0.400%. The Company will also be required to pay customary letter of credit fees, as necessary.

As of December 31, 2019, the Company did not have an outstanding debt balance under the Second A&R Credit Facility, and availability was $143.3

million. The Second A&R Credit Facility matures and all outstanding amounts become due and payable on May 9, 2022.

The Second A&R Credit Agreement contains customary conditions to borrowings, events of default and covenants, including covenants that restrict

our ability to sell assets, make changes to the nature of our 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 Second A&R Credit Agreement
also requires the Company to maintain compliance with (a) a maximum ratio of consolidated funded debt to consolidated EBITDA of 3.50 to 1.00 and (b) a
minimum ratio of consolidated EBITDA to interest expense of at least 3.00 to 1.00. As of December 31, 2019, the Company was in compliance with all
covenants.

The Company entered into the Second A&R Credit Agreement primarily to lower its borrowing costs and to change from an asset-based structure to a

cash-flow based structure.

Note 8—Leases

The Company has operating leases for its offices. Its leases have remaining lease terms of up to 11 years, some of which include options to extend the
leases for up to 5 years, and some of which include options to terminate the leases within 1 year with proper notification. Certain leases contain provisions for
property-related costs that are variable in nature for which the Company is responsible, including common area maintenance and other property operating
services. These costs are calculated based on a variety of factors including property values, tax and utility rates, property services fees, and other factors. The
Company records rent expense for operating leases, some of which have escalating rent payments, on a straight-line basis over the lease term. The Company
does not have any finance leases.

As of December 31, 2019, the Company is authorized to issue 1,095,000,000 shares of common stock, par value $0.000001 per share, and
100,000,000 shares of preferred stock, par value, $0.000001 per share. The authorized common stock consists of 1,000,000,000 shares of Class A common
stock and 95,000,000 shares of Class B common stock. The Class A and Class B have the same rights and preferences including rights to dividends, except
the Class B is entitled to ten votes per share and the Class A is entitled to one vote per share. Each share of Class B common stock is convertible at any time
at the option of the holder into one share of Class A common stock. In addition, each share of Class B common stock will convert automatically into one
share of Class A common stock upon any transfer, except for certain transfers described in the Company’s restated certificate of incorporation, including,
without limitation, certain transfers for tax and estate planning purposes.

No shares of preferred stock are outstanding as of December 31, 2019 and 2018. The Company’s board of directors has the discretion to determine the

rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences,
of each series of preferred stock.

cash-based awards under its 2016 Incentive Award Plan. As of December 31, 2019, 4.5 million shares remained available for grant under the Company’s 2016
Incentive Award Plan. The number of shares authorized for grant is subject to increase each year on January 1, equal to the lesser of (a) 4% of the common
stock outstanding (on an as-converted basis) on the final day of the immediately preceding calendar year and (b) such smaller number of shares as determined
by the board of directors. On January 1, 2020, the number of shares authorized for grant under the Company’s 2016 Incentive Award Plan was increased by
1.8 million shares in accordance with plan provisions.

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

Stock-based compensation expense related to restricted stock was $17.9 million, $7.4 million and $2.7 million for the years ended December 31, 2019,

2018 and 2017, respectively. At December 31, 2019, the Company had unrecognized employee stock-based compensation relating to restricted stock of
approximately $47.9 million, which is expected to be recognized over a weighted-average period of 2.5 years.

On November 30, 2018, the Company entered into a transition agreement with its Chief Operating Officer (the “Transition Agreement”), which
transition period is expected to end by June 30, 2019. Among other terms of the Transition Agreement, the Company granted a performance-based restricted
stock award for 24,000 shares of the Company’s common stock subject to time-and performance-based vesting (the “PSUs”). The PSUs are included in the
restricted stock activity for the year ended December 31, 2019 and 2018.

Employee Stock Purchase Plan

In September 2016, the Company established an ESPP with 800,000 shares of Class A common stock available for issuance. As of December 31,
2019, 0.3 million shares remained available for grant under this plan. The number of shares authorized for grant is subject to increase each year on January 1,
equal to the lesser of (a) 800,000 shares, (b) 1% of the common stock outstanding (on an as-converted basis) on the final day of the immediately preceding
calendar year, and (c) such smaller number of shares as determined by the Company’s board of directors. On January 1, 2020, the number of shares available
for issuance under the Company’s Employee Stock Purchase Plan was increased by 0.5 million shares in accordance with plan provisions.

Under the ESPP, all eligible employees are permitted to authorize payroll deductions of up to 100% of their compensation to purchase shares of Class

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

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

Expected term (years)
Expected volatility
Risk-free interest rate
Estimated dividend yield

The ESPP has a six-month holding period with respect to common stock purchases. Due to the holding period, the Company applies a discount to

reflect the non-transferability of the shares. Stock-based compensation expense related to ESPP totaled $25.7 million, $17.1 million and $10.7 million for the
years ended December 31, 2019, 2018 and 2017, respectively. At December 31, 2019, the Company had unrecognized employee stock-based compensation
relating to ESPP awards of approximately $10.5 million, which is expected to be recognized over a weighted-average period of 0.5 years.

In April 2019, the Company completed a series of transactions resulting in changes to its international legal structure, including a transfer of certain

intellectual property rights among wholly owned subsidiaries, primarily to align its structure to its evolving operations. The Company recorded a $262.4
million deferred tax asset associated with this restructuring offset by a reserve for uncertain tax position of $51.0 million. Based on available objective
evidence, management believes it is not more-likely-than-not that these additional foreign deferred tax assets will be realizable as of December 31, 2019 and,
therefore, are offset by a full valuation allowance to the extent not offset by reserves from uncertain tax positions. Management applied significant judgment
in estimating the fair value of intangible assets, which involved the use of significant assumptions, including revenue growth rates, margins and discount
rates. 

As of each reporting date, the Company’s management considers new evidence, both positive and negative, that could impact management’s view with

regard to future realization of deferred tax assets. During 2019, management recorded a valuation allowance of $199.2 million against its U.K. net deferred
tax assets, based on the previous history of cumulative losses and the conclusion that future taxable profit may not be available for the utilization of the
deferred tax assets for U.K. income tax purposes.

As of December 31, 2019, the Company had net operating loss carryforwards in the U.K. of approximately $129.1 million, which can be carried
carryforward indefinitely. As of December 31, 2019, the Company had state and U.K. research and development tax credits of approximately $4.7 million and
$0.3 million, respectively, which can be carried forward indefinitely.

As of December 31, 2019, unremitted earnings of the subsidiaries outside of the U.S. were approximately $1.2 million, on which no state taxes have

been paid. The Company’s intention is to indefinitely reinvest these earnings outside the U.S. Upon distribution of those earnings in the form of a dividend or
otherwise, the Company would be subject to both state income taxes and withholding taxes payable to various foreign countries. The amounts of such tax
liabilities that might be payable upon repatriation of foreign earnings are not material.

As of December 31, 2019, the Company had gross unrecognized tax benefits of approximately $53.2 million, $47.1 million of which is a reduction to

deferred tax assets and the remaining $6.1 million which would affect the Company’s effective tax rate if recognized. As of December 31, 2018, the Company
had gross unrecognized tax benefits of approximately $4.3 million. The Company classifies liabilities for unrecognized tax benefits in other liabilities, non-
current.

The Company files U.S. federal, state, and foreign tax returns. The Company is currently under examination by the California Franchise Tax Board for

the years ended December 31, 2016 and 2017. The Company expects to reduce its unrecognized tax benefits by $0.4 million during the next twelve months.

The 2016 through 2018 U.S. federal tax returns and 2010 through 2018 state tax returns remain open to examination. The majority of the Company’s

foreign subsidiaries remain subject to examination by local taxing authorities for 2014 and subsequent years.

Note 12—Segment and 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.

Guarantees and Indemnification

In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to clients, vendors, lessors, business

partners, and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be
provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification
agreements with directors and certain officers and employees that will require the Company, among other things, to indemnify them against certain liabilities
that may arise by reason of their status or service as directors, officers or employees. No demands have been made upon the Company to provide
indemnification under such agreements, and thus, there are no claims that the Company is aware of that could have a material effect on the Company’s
balance sheet, statement of operations or statement of cash flows. Accordingly, no amounts for any obligation have been recorded as of December 31, 2019
and 2018.

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.

Employment Contracts

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

Item 9A. 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 Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), as of December 31, 2019. 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 December 31, 2019.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-
15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of our financial statements for external purposes in accordance with generally accepted accounting principles.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2019 using the criteria set forth by the
Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013). Based on its assessment, our
management, including our CEO and CFO, has concluded that our internal control over financial reporting was effective as of December 31, 2019.

The effectiveness of our internal control over financial reporting as of December 31, 2019 has been audited by PricewaterhouseCoopers LLP, our

independent registered public accounting firm, as stated in their report, which appears in Item 8 of this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

We transitioned to a new accounting and financial reporting system, which replaced our existing accounting and financial reporting system. The go-

live for this new system occurred during July 2019, and our system implementation was completed during the quarter ended September 30, 2019.
Management evaluated the process changes as a result of the system implementation, and where needed, modified the design of and the testing for operating
effectiveness of internal control over financial reporting. The modification to the design of and testing for operating effectiveness was specific to the new
accounting and financial reporting system’s functionalities and features. We did not identify any previously unidentified risks or design gaps as a result of the
system implementation. Testing for operating effectiveness of internal control over financial reporting has been completed for the fiscal year ended December
31, 2019, and management concluded that the internal control over financial reporting under the new accounting and financial reporting system was operating
effectively.

There have been no significant changes in our internal control over financial reporting during the quarter ended December 31, 2019 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.

DESCRIPTION OF THE COMPANY’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

EXHIBIT 4.5

As of December 31, 2019, The Trade Desk, Inc. (“Company,” “we,” “us,” and “our”) had one class of securities registered under Section 12 of the Securities
Exchange Act of 1934, as amended (the “Securities Act”): our Class A common stock.

DESCRIPTION OF CLASS A COMMON STOCK

Our authorized capital stock consists of 1,095,000,000 shares of common stock, par value $0.000001 per share, and 100,000,000 shares of preferred

stock, par value $0.000001 per share. Our common stock is divided into two classes, Class A common stock and Class B common stock. Our authorized
Class A common stock consists of 1,000,000,000 shares and our authorized Class B common stock consists of 95,000,000 shares.

The following description of our capital stock and provisions of our certificate of incorporation and bylaws are summaries and are qualified by

reference to our certificate of incorporation and bylaws, each of which is an exhibit to our Annual Report on Form 10-K for the year ended December 31,
2019.

Voting Rights

Holders of our Class A common stock and Class B common stock have identical rights, provided that, except as otherwise expressly provided in our
certificate of incorporation or required by applicable law, on any matter that is submitted to a vote of our stockholders, holders of our Class A common stock
are entitled to one vote per share of Class A common stock and holders of our Class B common stock are entitled to 10 votes per share of Class B common
stock. Unless otherwise required by applicable law or described herein or in our certificate of incorporation, holders of shares of Class A common stock and
Class B common stock vote together as a single class on all matters (including the election of directors) submitted to a vote of stockholders.

Under the terms of our certificate of incorporation, we may not increase or decrease the authorized number of shares of Class A common stock or

Class B common stock without the affirmative vote of the holders of a majority of the voting power of the outstanding shares of our capital stock entitled to
vote, voting together as a single class. In addition, we may not issue any shares of Class B common stock (other than upon exercise of options or other rights
to acquire Class B common stock or in connection with a reclassification or dividend), unless that issuance is approved by the affirmative vote of the holders
of a majority of the outstanding shares of Class B common stock.

We have not provided for cumulative voting for the election of directors in our certificate of incorporation.

Economic Rights

Except as otherwise expressly provided in our certificate of incorporation or required by applicable law, shares of Class A common stock and Class B

common stock have the same rights and privileges and rank equally, share ratably and are identical in all respects as to all matters, including, without
limitation, those described below.

Dividends.    Any dividend or distributions paid or payable to the holders of shares of Class A common stock and Class B common stock shall be paid
pro rata, on an equal priority, pari passu basis, unless different treatment of the shares of each such class is approved by the affirmative vote of the holders of a
majority of the outstanding shares of Class A common stock and Class B common stock, each voting separately as a class; provided, however, that if a
dividend or distribution is paid in the form of Class A common stock or Class B common stock (or rights to acquire shares of Class A common stock or
Class B common stock), then the holders of the Class A common stock shall receive Class A common stock (or rights to acquire shares of Class A common
stock) and holders of Class B common stock shall receive Class B common stock (or rights to acquire shares of Class B common stock).

Subdivisions and Combinations.    If we subdivide or combine in any manner outstanding shares of Class A common stock or Class B common stock,

then the outstanding shares of all common stock will be subdivided or combined in the same proportion and manner.

 
 
 
 
   
 
 
 
 
 
 
 
 
Change of Control Transaction.    In connection with any change of control transaction (as defined in our certificate of incorporation), the holders of

Class A common stock and Class B common stock will be treated equally and identically with respect to shares of Class A common stock or Class B common
stock owned by them, unless different treatment of the shares of each class is approved by the affirmative vote of the holders of a majority of the outstanding
shares of Class A common stock and Class B common stock, each voting separately as a class.

Conversion

Each share of Class B common stock is convertible at any time at the option of the holder into one share of Class A common stock. In addition, each
share of Class B common stock will convert automatically into one share of Class A common stock upon any transfer, whether or not for value and whether
voluntary or involuntary or by operation of law, except for certain transfers described in our restated certificate of incorporation, including, without limitation,
certain transfers for tax and estate planning purposes. In addition, upon the earlier of (1) the date on which the outstanding shares of Class B common stock
represent less than 9.1% of the aggregate number of the then outstanding shares of Class A common stock and Class B common stock and (2) the affirmative
vote or written consent of the holders of at least 66 2/3% of the outstanding shares of Class B common stock, all outstanding shares of Class B common stock
shall convert automatically into Class A common stock, and no additional shares of Class B common stock will be issued.

Choice of Forum

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative form, 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 stockholders owed to us or our stockholders; (3) any action asserting a claim against us 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. Our certificate of incorporation also provides that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock
will be deemed to have notice of and to have consented to this choice of forum provision. It is possible that a court of law could rule that the choice of forum
provision contained in our certificate of incorporation is inapplicable or unenforceable if it is challenged in a proceeding or otherwise. This choice of forum
provision has important consequences for our stockholders. Our certificate of incorporation provides that the Court of Chancery of the State of Delaware will
be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to choose other forums for
disputes with us or our directors, officers or employees.

Preferred Stock – Limitations on the Rights of Holders of Class A Common Stock

Under the terms of our certificate of incorporation, our board of directors is authorized to direct us to issue shares of preferred stock in one or more

series without stockholder approval. Our board of directors has the discretion to determine the rights, preferences, privileges and restrictions, including voting
rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.

The issuance of preferred stock could adversely affect the voting power of holders of our common stock and the likelihood that such holders will

receive dividend payments and payments upon liquidation. The issuance of preferred stock, while providing flexibility in connection with possible
acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage
a third party from seeking to acquire, a majority of our outstanding voting stock.

Anti-Takeover Provisions

We are subject to Section 203 of the Delaware General Corporation Law. Subject to certain exceptions, Section 203 prevents a publicly held
Delaware corporation from engaging in a “business combination” with any “interested stockholder” for three years following the date that the person became
an interested stockholder, unless

2

 
 
 
 
 
 
 
 
 
 
 
 
the interested stockholder attained such status with the approval of our board of directors or unless the business combination is approved in a prescribed
manner. A “business combination” includes, among other things, a merger or consolidation involving us and the “interested stockholder” and the sale of more
than 10% of our assets. In general, an “interested stockholder” is any entity or person beneficially owning 15% or more of our outstanding voting stock and
any entity or person affiliated with or controlling or controlled by such entity or person.

Dual-Class Common Stock

As described above, our certificate of incorporation provides for a dual class common stock structure, which provides our founders, pre-IPO
investors, executives and employees with significant influence over all matters requiring stockholder approval, including the election of directors and
significant corporate transactions, such as a merger or other sale of our company or its assets.

Removal of Directors

Our certificate of incorporation and our bylaws provide that a director may be removed only for cause and only by the affirmative vote of the holders
of at least 66 2/3% of the votes that all of our stockholders would be entitled to cast in an annual election of directors. Any vacancy on our board of directors,
including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office.

The limitations on the removal of directors and filling of vacancies could make it more difficult for a third party to acquire, or discourage a third party

from seeking to acquire, control of our company.

Super-Majority Voting

The Delaware General Corporation Law provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is

required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws, as the case may be,
requires a greater percentage. Our bylaws may be amended or repealed by a majority vote of our board of directors or the affirmative vote of the holders of at
least 66 2/3% of the votes that all of our stockholders would be entitled to cast in an annual election of directors. In addition, the affirmative vote of the
holders of at least 66 2/3% of the votes which all our stockholders would be entitled to cast in an election of directors is required to amend or repeal or to
adopt any provisions inconsistent with any of the provisions of our certificate of incorporation described in this paragraph and the prior two paragraphs.

Stockholder Action; Special Meeting of Stockholders

Our certificate of incorporation provides that any action required or permitted to be taken by our stockholders must be effected at a duly called annual

or special meeting of such stockholders and may not be effected by any consent in writing by such stockholders. Our certificate of incorporation and our
bylaws also provide that, except as otherwise required by law, special meetings of our stockholders can only be called by our chairman of the board (or in the
event of co-chairmen, either chairman), our chief executive officer, our president (if there is no chief executive officer) or our board of directors.

Authorized But Unissued Shares

The authorized but unissued shares of our common stock and preferred stock are available for future issuance without stockholder approval, subject

to any limitations imposed by the listing standards of the NASDAQ Global Market (“NASDAQ”). These additional shares may be used for a variety of
corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved common stock and preferred
stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.
