Our Company

We are a leading software platform for digital media measurement and analytics. Our mission is to increase the effectiveness and transparency of the digital advertising ecosystem. Through our software platform and the metrics it provides, we help preserve the fair value exchange in the digital advertising marketplace.

The advertising industry continues to shift from traditional mediums to an expanding array of digital channels and platforms. Digital advertisers have historically relied on inconsistent, self-reported data from a large number of publishers, social channels and programmatic platforms, making it difficult to form an accurate, unbiased view of how and where their ad budgets are spent. As objectionable content and ad fraud have proliferated across the Internet and other digital channels, advertisers are utilizing independent, third-party solutions to protect their brand equity and optimize the performance of their digital media investments.

Our technology addresses this need by providing unbiased data analytics that enable advertisers to increase the effectiveness, quality and return on their digital advertising investments. Our proprietary DV Authentic Ad metric is our definitive metric of digital media quality which measures whether a digital ad is displayed in a fraud-free, brand-safe environment and is fully viewable in the intended geography. Our software platform delivers this metric to our customers in real time, allowing them to access critical performance data on their digital ads. Customers then leverage our data analytics to improve the efficiency of their digital advertising investments by avoiding wasted media spend on blocked or fraudulent ads and to optimize their media strategies in real time by verifying their highest performing ads and content.

Our software platform is integrated across the entire digital advertising ecosystem, including programmatic platforms, social media channels and digital publishers. We deliver unique data analytics through our customer interface to provide detailed insights into our customers’ media performance on both direct and programmatic media buying platforms and across all key digital media channels (including social, video, mobile in-app and connected TV (“CTV”)), formats (including display and video) and devices (including mobile, desktop and connected televisions). Our technology enables programmatic media traders to evaluate approximately 220 billion transactions daily, ensuring that a digital ad meets advertiser- defined quality criteria before it is purchased. We also analyze more than 6.5 billion digital ad transactions daily, measuring whether ads are delivered in a fraud-free, brand-safe environment and are fully viewable in the intended geography. Our software platform and unique position in the advertising ecosystem allows us to develop a significant data asset that accumulates over time as we measure an increasing number of media transactions. We are able to leverage our data asset across our existing solutions as well as expand the data asset to launch new solutions that address the evolving needs of advertisers.

Our blue-chip customer base includes many of the largest global brands. We serve over 1,000 customers that are diversified across all major industry verticals, including consumer packaged goods, financial services, telecommunications, technology, automotive and healthcare. In 2020, we had 45 customers who each represented at least $1 million of annual revenue, up from 41 such customers in 2019 and 25 in 2018, with no customer representing more than 10% of our revenue in either 2019 or 2020. We serve our customers globally through our 24 offices in 15 countries, including the United States, the United Kingdom, Israel, Singapore, Australia, Brazil, France, Germany and Japan.

1

We generate revenue from our advertising customers based on the volume of media transactions, or ads, that our software platform measures (“Media Transactions Measured”), for which we receive an analysis fee (“Measured Transaction Fee”), enabling us to grow as our customers increase their digital ad spend and as we integrate into new channels and platforms. We have long-term relationships with many of our customers, with an average relationship of almost six years for our top 75 customers and almost seven years for our top 25 customers, and ongoing contractual agreements with a substantial portion of our customer base. We have maintained exceptional customer retention with gross revenue retention rates of over 95%, and 100% retention of our top 75 customers, in each of 2020, 2019 and 2018. We are also able to increase revenue per customer as we introduce new solutions, which has resulted in a compounded annual growth in average revenue for our top 50 customers of 29% from 2017 to 2020. The combination of high customer retention and multiple upsell opportunities has resulted in net revenue retention rates of 123% in 2020, 156% in 2019 and 131% in 2018. We have delivered strong historical revenue growth, with a compounded annual growth rate of 50% from 2017 to 2020.

We generated revenue of $227.2 million in the nine months ended September 30, 2021 and $165.3 million in the nine months ended September 30, 2020, representing an increase of 37%. We generated revenue of $243.9 million in the year ended December 31, 2020 and $182.7 million in the year ended December 31, 2019, representing an increase of 34%. We generated revenue of $182.7 million in the year ended December 31, 2019 and $104.3 million in the year ended December 31, 2018, representing an increase of 75%. We generated net income of $1.0 million in the nine months ended September 30, 2021, $20.5 million in the year ended December 31, 2020, $23.3 million in the year ended December 31, 2019 and $3.2 million in the year ended December 31, 2018. We generated Adjusted EBITDA of $69.3 million in the nine months ended September 30, 2021, or 31% of revenue, $73.2 million in the year ended December 31, 2020, or 30% of revenue, $69.0 million in the year ended December 31, 2019, or 38% of revenue, and $26.6 million in the year ended December 31, 2018, or 25% of revenue. Adjusted EBITDA is a financial measure not presented in accordance with generally accepted accounting principles (“GAAP”). For a definition of Adjusted EBITDA, an explanation of our management’s use of this measure and a reconciliation of Adjusted EBITDA to net income, see “Summary Historical Consolidated Financial Data.”

Our Industry

We believe that our business benefits from many of the most significant trends in digital marketing and advertising, including:

Significant Growth in Digital Ad Spend. The global advertising industry represented $569 billion of ad spend in 2020, according to Magna Global, and continues to shift from traditional forms of media to digital channels and platforms. According to Magna Global, global digital ad spend, excluding search, reached over $170 billion in 2020 and is expected to grow to $225 billion by 2023. We believe the shift towards digital spend will continue as new distribution channels and advertising formats emerge that enable advertisers to more effectively reach their target audiences.

2

Acceleration of Programmatic Ad Buying. Advertisers are increasingly shifting their digital media buying to programmatic platforms, which automate the digital ad buying process through the use of computer algorithms and deliver targeted advertisements utilizing vast data sets. According to Magna Global, global programmatic ad spend was approximately $51 billion in 2020 and is expected to reach $75 billion in 2023 and grow nearly twice as fast as the rest of the digital advertising market over the next five years. Programmatic ad buyers and trading platforms benefit from consistent access to high quality and accurate data to improve purchasing decisions and optimize the efficacy of their ads. Furthermore, advertisers value having a single, unified data source that they can leverage to help make real-time decisions on programmatic ad placements across all channels and formats.

Emergence of CTV and Other New Digital Channels. Over time, the emergence of new digital channels, such as social, has attracted significant advertiser interest and investment. In turn, this has created additional demand for digital measurement solutions. According to Magna Global, global digital ad spend on social channels was approximately $87 billion in 2020 and is expected to reach over $120 billion by 2023. Today, CTV represents a large new frontier for digital advertising as the approximately $150 billion of annual global linear television media spend starts to migrate to digital channels. According to eMarketer, there was expected to be over $8 billion of CTV ad spend in the U.S. in 2020 which is expected to double by 2023, with over 50% of ad inventory projected to be bought through programmatic platforms. CTV presents a significant opportunity for full-suite measurement providers due to the fragmented inventory and ad fraud emerging within this channel. Based on the Company Data Analysis, CTV fraud impressions more than tripled from 2019 to 2020.

Importance of Brand Reputation. With the increasing scale of digital media channels, advertisers are placing a greater emphasis on understanding where their ads are placed and the content with which it is presented. Context of ad placement has become as important to a brand as the content of the ad itself. Determining the context and content of a web page, streaming video or social post is more complex than verifying a keyword or article headline and often varies minute-by-minute. This challenge is further complicated by a significant increase in user-generated content, as ad spend on social platforms continues to expand. According to a recent study that we commissioned with The Harris Poll, nearly two-thirds of consumers expressed that they would stop using a brand or product that advertises next to false, objectionable or inflammatory content. More than ever, advertisers are being held accountable for brand and content alignment. In response, advertisers are adopting scalable, sophisticated brand safety and suitability solutions to ensure effective use of their global digital media spend.

Desire to Improve Media Quality and Effectiveness. The significant growth in digital advertising has resulted in increased fraud and wasted ad spend due to ads that are never seen. Juniper Research estimated that approximately $42 billion of global digital media spend was wasted in 2019 as a result of continually evolving ad fraud activities, including bots, fake clicks and fraudulent web sites. New and sophisticated schemes, particularly across emerging channels such as CTV and mobile in-app, are uncovered each day. We have identified over 5,000 fraudulent CTV apps as of December 31, 2020, and we have seen CTV fraud impressions increase 220% in 2020 as compared to 2019. In addition, even when an ad is verified to be fraud- free, there is no certainty that it is actually viewable. According to Merkle, more than 40% of digital ads placed are deemed to be not viewable. To combat these issues, advertisers, digital publishers and media platforms rely on robust measurement solutions to validate the performance of their marketing campaigns and ensure that they are only paying for verified ads.

Rising Adoption of Independent, Cookie-Less, Cross-Platform Measurement Solutions. The proliferation of digital channels, formats and devices has made it more difficult for advertisers to measure campaign performance across all platforms. This measurement has been further complicated by recent moves by some large device manufactures and certain closed platforms, which are often referred to as “walled gardens,” to restrict cookie and identifier-based data sharing. As a result, advertisers are increasingly adopting full-suite measurement solutions that are not dependent on cookies or cross-site individual-level data trackers and can be used seamlessly across devices, the open web and the walled gardens. Point solutions that only deliver single metrics, often on a limited amount of media, and which are based on challenged data aggregation methods, continue to lose traction with advertisers. This has created a growing demand for independent, third-party providers that provide accredited and unified data analytics that improve the transparency and effectiveness of digital ad spend across the entire ecosystem without relying on cookies. Based on the Company Data Analysis, the total addressable market for our core solutions was less than 25% penetrated in 2020, and we believe that we have the opportunity to expand our customer base in response to increasing demand for our core measurement solutions.

What We Do

We are a leading software platform for digital media measurement and analytics. Our leadership in our industry is based on our differentiated technical capabilities resulting from years of innovation, our breadth of industry accredited solutions, and an expansive network of integration partners that enable us to analyze media transactions across the global digital ecosystem. Our solutions

3

empower our customers to address the evolving and intensifying complexities of measuring the performance of digital advertising. We deliver our suite of solutions through a robust and scalable software platform that provides our customers with unified data analytics. Our broad market coverage of the digital advertising ecosystem and our leading software platform enables us to analyze billions of data points globally each day. We collected and analyzed data points on the approximately 3.2 trillion Media Transactions Measured by us in 2020, up from 2.4 trillion Media Transactions Measured in 2019 and 1.4 trillion in 2018. This volume has enabled us to build a self-reinforcing, proprietary data asset which we redeploy in new solutions that further enhance and expand the analytics that we can deliver to our customers and partners.

Our Solutions

The DV Authentic Ad

The DV Authentic Ad is our definitive metric of digital media quality, which evaluates the existence of fraud, brand safety, viewability and geography for each digital ad:

● Fraud: Our solutions are designed to safeguard advertisers against increasingly sophisticated invalid digital traffic, such as bot fraud, site fraud, malware (including adware), and app fraud. We continuously monitor and analyze billions of delivered digital ads on a daily basis for aberrant activity in order to detect new fraud schemes. Each day, we identify over 500,000 active fraudulent device signatures, distributing them to our partners nearly 100 times per day, thereby enhancing the protection we provide our customers.

● Brand Safety: Our customers use the data analytics that our software platform provides to help prevent their ads from appearing next to content that they do not deem appropriate for their brands and target desired contexts. Our brand safety and suitability solutions evaluate the full context of a webpage including the URL and the specific content. Customers can use our extensive content categories to target desired contexts for their ads, without relying on personal data or cookies. We also offer Authentic Brand Safety, which is an enhanced set of contextual targeting solutions that can be deployed across multiple programmatic platforms.

● Viewability: Digital ads are frequently obscured, paused before fully delivered or placed in locations that are out of view from the intended recipient. We help our customers determine if their ads are in-view by the recipient of each advertisement by providing advanced viewability metrics, including average time-in-view, key message exposure and video player size. Our solutions also leverage our historical data to predict the viewability of ads to optimize programmatic buying decisions.

● Geography: Many of our customers run distinct media campaigns that are targeted toward distinct geographic regions. The intended geography of these media campaigns may be specified due to the content or offer of the digital ad, the language in which it is presented or for compliance reasons. Our customers leverage our solutions to ensure that their geographic targeting requirements are met and that there is language alignment between the digital ad and the intended geographic region.

DV Authentic Attention

We developed DV Authentic Attention, a predictive measure of digital ad performance, by leveraging the data we aggregate to deliver our DV Authentic Ad. Developed in 2020 and released in February 2021, DV Authentic Attention is a performance measurement solution that we believe is the industry’s most comprehensive evaluation of creative exposure and user engagement with a digital ad. When employed by our customers, DV Authentic Attention provides comprehensive, real-time prediction data that helps drive media campaign performance in a privacy-friendly manner, as an alternative to individual reach and frequency performance tools. DV Authentic Attention evaluates the real-time delivery of a digital ad by analyzing dozens of data points on the exposure of the digital ad and the consumer’s engagement with the ad and device. DV Authentic Attention evaluates the entire presentation of an ad through metrics that include viewable time, share of screen, video presentation and audibility. Our customers use DV Authentic Attention to predict which ads will impact consumers and drive outcomes, enabling them to make changes to their media strategies in real time.

4

Custom Contextual

In late 2020, we launched our Custom Contextual solution to enhance our programmatic advertising solutions. Advertisers use our Custom Contextual solution to match their ads to relevant content in order to maximize user engagement and drive campaign performance. Custom Contextual metrics leverage our content-derived analytics data and are not reliant on third-party cookies or cross-site tracking technology. Custom Contextual enables advertisers to target audiences based on key points of interest even in web browsers and operating systems that have phased out or ended the use of third-party tracking technology, thus also positioning them to align with existing privacy regulations.

Supply-Side Solutions

We provide our software solutions and data analytics to publishers and other supply-side customers to enable them to maximize revenue from their digital advertising inventory. Supply-side advertising platforms (such as ad networks and exchanges) utilize our data analytics to validate the quality of their ad inventory and provide metrics to their customers to facilitate the targeting and purchasing of digital ads. We also provide the DV Publisher Suite, a unified solution for digital publishers to manage revenue and increase inventory yield by improving video delivery, identifying lost or unfilled sales, and better aggregate data across all inventory sources.

How We Deploy Our Solutions

We provide a consistent, cross-platform measurement standard across all major forms of digital media, making it easier for advertiser and supply-side customers to benchmark performance across all of their digital ads and to optimize their digital strategies in real time. Our coverage spans over 40 key geographies where our customers are located and includes:

● all primary media buying platforms, including direct and programmatic;

● all significant digital media channels, including social, video, mobile in-app and CTV;

● all key media formats, including display and video; and

● all major devices, including mobile, desktop and connected televisions.

We also maintain an expansive set of direct integrations across the entire digital advertising ecosystem in order to deliver our metrics to the platforms where our customers buy ads. Our partner integrations include leading programmatic platforms, such as The Trade Desk, Google Display & Video 360, Amazon Advertising and Verizon Media. Through these integrations, our customers utilize our solutions to better evaluate and optimize inventory purchase decisions. We also have direct integrations and partnerships with key social platforms, including Facebook, YouTube, Twitter, Pinterest, TikTok and Snap, as well as leading CTV platforms, including Amazon and Roku, which allow us to deliver more robust social campaign and CTV data analytics to our advertiser customers. Together, we work seamlessly to empower our partners by providing advertisers clarity and confidence in their digital investments across all key platforms.

Our Strengths

We believe the following attributes and capabilities form our core strengths and provide us with competitive advantages:

Best-in-Class Software Platform. Our technology stack enables us to develop proprietary advertising performance metrics on each digital ad transaction. This precision sets us apart from our competitors and allows us to combine and deliver performance measurements across fraud, brand safety, viewability and geography into a single, unique metric (the DV Authentic Ad), as well as the flexibility to disaggregate and analyze the individual measurements for each delivered ad. We believe we are able to provide the most robust data analytics in the industry, analyzing hundreds of data points for each delivered ad and across billions of ads every day, with approximately 3.2 trillion Media Transactions Measured by us in 2020.

Broad Ecosystem Coverage. We provide comprehensive performance measurement metrics across all key digital channels where our customers advertise and deliver them through the major platforms through which they purchase advertising. Our technology is integrated into major platforms that provide direct, programmatic and social advertising, including Google, Facebook and The Trade Desk. As new media formats emerge, the strength of our solutions and the flexibility of our software platform allows us to seamlessly

5

onboard new integration partners and secure new partnerships as selling channels for our solutions. For example, as CTV continues to become an increasingly prominent advertising channel, we have secured partnership agreements with multiple leading CTV platforms, including Amazon and Roku, that have certified our measurement solutions for use on their platforms. We believe that we provide the broadest integration and partnership coverage across the industry.

Powerful Network Effect Fueled by a Robust and Scalable Data Asset. Our software platform and unique position in the advertising ecosystem allows us to develop a significant data asset that accumulates over time as we measure an increasing number of media transactions. This virtuous cycle allows us to deliver better results as we build broader data sets and enables us to enhance and expand the solutions we deliver to customers. We collected and analyzed data points on the approximately 3.2 trillion Media Transactions Measured by us in 2020, up from 2.4 trillion Media Transactions Measured in 2019 and 1.4 trillion in 2018. The knowledge from the billions of detailed data points we gather daily has enabled us to develop an extensive data asset that we leverage across our existing solutions as well as expand the data asset to launch new solutions that address the evolving needs of advertisers. The strength of our solutions attracts new customers which increases the ad transactions we measure and data we collect, further strengthening the value of our network.

Compelling Value Proposition Driving High Customer ROI. We enable our customers to optimize return on their marketing investments for a fraction of the underlying media cost. Our unique data analytics are used by our advertiser customers to target the highest performing ad inventory and receive refunds or credits for digital ads that do not meet certain criteria. In addition, our solutions help our customers preserve one of their most important and invaluable assets — brand reputation — by ensuring ads are not shown near content that is inconsistent with their brand message.

Track Record of Successful Product Innovation. We have a track record of developing new solutions for our customers that provide increased relationship value and drive incremental average revenue per customer, thereby deepening our competitive edge. As of November 1, 2021, we had 133 software and data engineers throughout our five research and development centers focused on product development. We launched our first brand safety solution in 2010 and have continued to develop leading-edge solutions ever since. We have continued our track record of innovation in recent years as demonstrated by the launch of Authentic Brand Safety, which we believe is the industry’s only solution that allows advertisers to programmatically avoid unsuitable content across platforms using the same settings established for post-bid evaluation. In 2019, we launched our first CTV solutions which now detect over 100,000 fraudulent device signatures per day, providing significant savings to our clients by preventing wasted ad spend. In 2020, we developed DV Authentic Attention, which we believe is the first solution in the market to combine dozens of ad exposure and user engagement metrics on individual impressions to provide predictive analytics and improve performance outcomes, and introduced our Custom Contextual solution, which allows advertisers to match their ads to relevant content without depending on cookie-based or cross-site tracking.

Loyal and Growing Customer Base. Our customers represent many of the largest advertisers in the world including Colgate-Palmolive, Ford, Mondelēz and Pfizer. In each of 2020, 2019 and 2018, we maintained over 95% gross revenue retention rates across our customer base and retained 100% of our top 75 customers. With this foundation, we were able to drive net revenue retention of 123% in 2020, 156% in 2019 and 131% in 2018 through increased advertising volume and the successful launch of newly-introduced solutions. This growth in our existing customer base together with strong new customer wins has increased the number of customers contributing over $1 million of revenue to 45 customers in 2020, up from 41 in 2019 and 25 in 2018.

Scaled and Profitable Business Model. We have an attractive operating model, driven by the scalability of our platform, the consistent nature of our revenue, our significant operating leverage and low capital intensity. Our platform allows us to provide large-scale data analytics to customers around the world seamlessly and cost-effectively. We are able to scale our solutions efficiently and with limited incremental cost for new customers and additional solutions. Our cost of sales (excluding depreciation and amortization) represented only 15% of revenues and helped deliver an Adjusted EBITDA margin of 30% in 2020. We have grown our business rapidly while also achieving profitability, demonstrating the strength of our platform and business model. For additional detail on cost of sales excluding depreciation and amortization, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations.”

Well-Aligned with Privacy Restrictions and Platform Evolution. We believe that we are well positioned to benefit from broader government regulations and changing industry privacy standards that increasingly restrict the collection and use of personal data for advertising purposes. Additionally, as device manufactures and walled garden platforms aggressively move to curtail the use of cookie-based data collection across their properties, measurement, targeting and advertising analytics solutions that are not based on these tracking and collection tools will benefit. Our core software platform does not rely on third-party cookies, persistent identifiers

6

or cross- site tracking technology to deliver our measurement and analytics solutions. Additionally, the core contextual data set that we use to provide our measurement and analytics solutions can also provide advertisers with an alternative source of data to deliver targeted advertising. To capitalize on this rapidly evolving environment, and to leverage a system that is not reliant on cookie-based or personalized data collection, we introduced our Custom Contextual solution in late 2020, which allows advertisers to match their ads to relevant content in order to maximize user engagement and drive campaign performance, without depending on cookie-based or cross-site tracking. In February 2021, we released DV Authentic Attention, a performance measurement solution that leverages pseudonymous, privacy-friendly data to analyze advertising engagement, as an alternative to individual reach and frequency performance tools. As privacy restrictions evolve, and tracking identifiers such as cookies become increasingly restricted by walled gardens, we believe there will be increased demand for our contextual targeting and performance solutions.

Proven Management Team. We have a strong management team that has extensive experience leading software and digital marketing companies. We believe that our management team will continue to drive our growth, scale and solutions innovation. Furthermore, our Chief Executive Officer, Mark Zagorski, has significant public company experience, including as Chief Executive Officer of a public company in the digital advertising software industry.

Our Opportunity

There is strong global demand across the advertising ecosystem for independent third-party measurement and authentication of digital ads. Advertisers, programmatic platforms, social media channels and digital publishers are collectively placing increased emphasis on the quality and effectiveness of digital ad spend across all channels, formats and devices. According to Magna Global, there was over $170 billion of global digital ad spend in 2020 where our solutions are directly applicable.

We are a leader in a large, fast-growing and underpenetrated market with significant tailwinds. Based on the Company Data Analysis, we estimate that the total addressable market for our core solutions was approximately $13 billion globally in 2020 and was less than 25% penetrated and is expected to grow to approximately $20 billion by 2025 with less than 50% penetration. We believe our market leadership positions us well to generate significant growth across this large, underserved market. Our growth is primarily driven by the fastest growing segments of digital ad spend, which are currently among the least penetrated with our solutions, including mobile in-app, programmatic, social and CTV.

Our Growth Strategy

We intend to continue penetrating the digital advertising market through the following key growth levers:

Growing with Our Current Customers. We expect to continue to grow with our existing customers as they increase their spend on digital advertising and as we introduce new solutions. We expect the increased demand for third-party digital advertising data analytics to fuel continued adoption of our solutions across key channels, formats, devices and geographies. For example, we expect new solutions like Authentic Brand Safety, DV Authentic Attention and Custom Contextual and the ongoing shift from linear TV to CTV to continue to drive growth from our existing customers.

Expanding Our Customer Base. We intend to continue targeting new advertiser, programmatic platform and digital publisher customers who have not yet adopted digital ad measurement solutions, as well as those currently utilizing solutions provided by our competitors or point solutions. With the total addressable market for our core solutions less than 25% penetrated today, we believe that there is ample room for us to add new customers going forward.

Expanding Our International Presence. We intend to continue to grow our presence in international markets in order to meet the needs of our existing customers and accelerate new customer acquisition in key geographies outside of North America. We have expanded into eighteen countries since 2018, which has accelerated our revenue growth in those markets.

Introducing New Solutions and Channels. We will continue to lead the industry in innovation by developing premium solutions that increase our value proposition to our existing customers. We have a strong track record of rolling out new solutions that have high adoption rates with our existing customers. We intend to extend our solutions capabilities to cover new and growing digital channels and devices, including CTV, new mobile apps and other emerging areas of digital ad spend.

Pursuing Opportunistic M&A. Our management team has a proven track record of identifying, evaluating, executing and integrating strategic acquisitions. We have completed four acquisitions since December 2018 to expand our technology and solutions

7

offerings and broaden our geographic footprint. We maintain an active pipeline of potential M&A targets and intend to continue evaluating add-on opportunities to bolster our current solutions suite and complement our organic growth initiatives.

Recent Developments

Acquisition of OpenSlate

On November 9, 2021, we announced an agreement to acquire Outrigger Media, Inc., d/b/a OpenSlate (“OpenSlate”), for $150 million, consisting of $125 million in cash and $25 million in our common stock. OpenSlate is a leading independent pre-campaign contextual targeting platform for social video and CTV. OpenSlate’s technology provides insight into the nature and quality of ad-supported content on large, video-driven social platforms, such as Facebook, TikTok and YouTube. The acquisition is expected to close before the end of the year.

Acquisition of Meetrics

On August 31, 2021, we acquired all of the outstanding stock of Meetrics GmbH (“Meetrics”), a European-based ad verification company headquartered in Berlin, Germany, in an all-cash transaction for $24.3 million. Meetrics offers comprehensive media quality measurement and solutions, across viewability, fraud, and brand safety and suitability, and is the only European provider that has established official ad verification measurement partnerships with the traditionally walled gardens. Acquiring Meetrics adds experienced sales, product and engineering teams and tenured customer relationships that accelerate the growth of our international operations. The Meetrics sales, product and engineering teams continue to operate from offices in the Europe, Middle East and Africa, or EMEA, region, fortifying and expanding our commercial operations in the region.

Initial Public Offering, Concurrent Private Placement and Secondary Transaction

On April 23, 2021, we completed our initial public offering (“IPO”) in which we issued and sold 9,977,452 shares of our common stock at a public offering price of $27.00 per share, which included the full exercise of the underwriters’ option to purchase 1,350,000 additional shares from us. We received aggregate net proceeds of $253.2 million from the IPO, after deducting underwriting discount fees of $16.2 million. In connection with the IPO, Providence VII U.S. Holdings L.P. (the “Providence Investor”) and certain of our other existing stockholders sold an aggregate of 5,355,883 shares of our common stock, which included the full exercise of the underwriters’ option to purchase 650,000 additional shares of our common stock from the Providence Investor. We did not receive any proceeds from the sale of shares by these stockholders.

On April 23, 2021, affiliates of Tiger Global Management, LLC (collectively, and individually, the “Tiger Investor”) purchased $30 million of our common stock in a private placement concurrent with the completion of the IPO (the “concurrent private placement”) at a price per share equal to the IPO price of $27.00, for a total of 1,111,111 shares of our common stock. We received aggregate net proceeds of $28.9 million from the concurrent private placement, after deducting fees of $1.0 million. In addition, the Tiger Investor purchased $30 million of our common stock from the Providence Investor in a secondary transaction concurrent with the completion of the IPO (the “secondary transaction”) at a price per share equal to the IPO price of $27.00, for a total of 1,111,111 shares of our common stock. We did not receive any proceeds from the secondary transaction. The shares sold to the Tiger Investor in the concurrent private placement and the secondary transaction were not registered and are “restricted securities” within the meaning of Rule 144 (as defined herein). See “Shares Available for Future Sale — Rule 144.”

Our Organizational Structure

The following chart presents an overview of our ownership and organizational structure, after giving effect to this offering, assuming the underwriters do not exercise their option to purchase additional shares. For additional information with respect to our ownership structure, see “Principal and Selling Stockholders”:

* Ownership percentages exclude shares of common stock issuable upon exercise of outstanding stock options and settlement of restricted stock units.

Ownership and Our Status as a Controlled Company

In August 2017, funds affiliated with Providence Equity Partners L.L.C., or “Providence,” entered into a definitive agreement to purchase a majority of the equity interests in our indirect subsidiary DoubleVerify Inc., a Delaware corporation, or the “Providence Acquisition”. The Providence Acquisition was consummated on September 20, 2017.

Providence is a premier asset management firm with approximately $45 billion in aggregate capital commitments. Providence pioneered a sector-focused approach to private equity investing with the vision that a dedicated team of industry experts could build exceptional companies of enduring value. Since the firm’s inception in 1989, Providence has invested in over 170 companies and has become a leading private equity firm specializing in growth-oriented investments in media, communications, education and technology.

After the completion of this offering, and based on the number of shares the Providence Investor expects to sell in this offering, the Providence Investor will hold approximately 51.9 % of our common stock (or approximately 51.1 % if the underwriters exercise in full their option to purchase additional shares from the selling stockholders). As a result, unless the Providence Investor decides to increase the number of shares it sells in this offering, we expect to continue to be a “controlled company” within the meaning of

9

NYSE rules and to rely on exemptions from certain corporate governance requirements otherwise applicable to NYSE-listed companies. See “Management — Corporate Governance.”

None of the information contained on, or that may be accessed through, our website or any other website identified herein is part of, or incorporated into, this prospectus.

Summary Risk Factors

Our business is subject to a number of risks, including risks that may prevent us from achieving our business objectives or may adversely affect our business, financial condition, results of operations, cash flows and prospects that you should consider before making a decision to invest in our common stock. These risks are discussed more fully under “Risk Factors” in this prospectus. These risks relate to, among other matters:

● our ability to respond to technological developments and evolving industry standards;

● our ability to compete with our current and future competitors;

● our ability to retain existing customers, obtain new customers and generate revenue from new customers;

● system failures, security breaches, cyberattacks or natural disasters that could interrupt the operation of our platform and data centers;

● the ability of our integration partners to accurately and timely pay us;

● defects, errors or inaccuracies associated with our platform;

● economic downturns and unstable market conditions (including as a result of the COVID-19 pandemic);

● our ability to integrate businesses acquired;

● our ability to retain our senior management team and other key personnel;

● the application, interpretation and enforcement of digital advertising and data privacy and protection laws and regulations;

● the assertion of third-party intellectual property rights and our ability to protect and enforce our intellectual property rights; and

● restrictions in the New Revolving Credit Facility (as defined herein).

Implications of Being an Emerging Growth Company

As a company with less than $1.07 billion in annual gross revenue during our last fiscal year, we qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the “JOBS Act”. An emerging growth company may take advantage of specified reduced reporting and other reduced requirements that are otherwise applicable generally to public companies. These provisions include:

● we may present only two years of audited financial statements and only two years of related Management’s Discussion and Analysis of Financial Condition and Results of Operations disclosure;

● we are exempt from the requirement to obtain an attestation and report from our auditors on the assessment of our internal control over financial reporting pursuant to the Sarbanes-Oxley Act of 2002, as amended, or the “Sarbanes-Oxley Act”;

10

● we are not required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board, or the “PCAOB”, regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (i.e., an auditor discussion and analysis);

● we are permitted to provide less extensive disclosure about our executive compensation arrangements, such as the correlation between executive compensation and performance and comparisons of the chief executive officer’s compensation to median employee compensation; and

● we are not required to give our stockholders nonbinding advisory votes on executive compensation or golden parachute arrangements (i.e., “say-on-pay,” “say-on-frequency” and “say-on-golden parachutes”).

In addition, under the JOBS Act, emerging growth companies can also delay adopting new or revised financial accounting standards until such time as those standards would otherwise apply to private companies. We have elected to avail ourselves of this exemption and, therefore, we will not be subject to new or revised accounting standards at the same time as other public companies that are not emerging growth companies.

We may take advantage of these provisions until December 31, 2026 (the last day of our fiscal year following the fifth anniversary of the date of the first sale of our common equity securities pursuant to our IPO) or until such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company if our annual gross revenues are $1.07 billion or more, if we issue more than $1 billion of non-convertible debt over a three-year period, or if we become a “large accelerated filer” as defined in the Securities Exchange Act of 1934, or the “Exchange Act”. We may choose to take advantage of some or all of these reduced burdens and, as such, the information that we provide stockholders may be different than the information you may receive from other public companies in which you hold equity interests. We do not know if some investors will find our common stock less attractive as a result of our utilization of these exemptions. The result may be a less active trading market for our common stock and increased volatility in the price of our common stock.

(1) Includes outstanding debt and capital lease obligations. As of December 31, 2020, we had $22.0 million outstanding under the New Revolving Credit Facility. On April 30, 2021, we used a portion of the net proceeds from the IPO and the concurrent private placement to pay the entire outstanding balance of $22.0 million under the New Revolving Credit Facility. See “Description of Certain Indebtedness.”

(2) In addition to our results determined in accordance with U.S. generally accepted accounting principles, or GAAP, we believe that certain non-GAAP financial measures, including Adjusted EBITDA and Adjusted EBITDA Margin, are useful in evaluating our business. A metric similar to Adjusted EBITDA is used in certain calculations under our New Revolving Credit Facility. We define Adjusted EBITDA as net income before income taxes, interest expense, depreciation and amortization (EBITDA), further adjusted for stock-based compensation, other (income) expense, M&A costs, offering costs and IPO readiness costs and other

13

costs. The following table presents a reconciliation of these non-GAAP financial measures to the most directly comparable financial measure prepared in accordance with GAAP.

(b) Option cancellation payments represent incremental cash-based compensation paid in connection with option cancellation agreements entered into on December 29, 2020 with three employee holders of certain performance-based stock options, pursuant to which an aggregate of 955,498 unvested options were cancelled for approximately $14.5 million in cash. The Company entered into these option cancellation agreements to provide liquidity to longstanding employees. This amount is recorded as an expense in our audited consolidated financial statements for the year ended December 31, 2020.

(c) M&A costs for the nine months ended September 30, 2021 consist of transaction costs related to the acquisition of Meetrics and other deferred compensation costs related to acquisitions. M&A costs for the nine months ended September 30, 2020 and the years ended December 31, 2020, 2019 and 2018 consist of third-party costs and deferred compensation costs related to acquisitions.

(d) Offering costs and IPO readiness costs for the nine months ended September 30, 2021 and 2020 and the years ended December 31, 2020, 2019 and 2018 consist of third-party costs incurred in preparation and completion of our IPO and other transaction related expenses. Included in IPO readiness costs for the year ended December 31, 2020 are $3.6 million of offering costs for registration fees, filing fees, and specific legal and accounting fees related to the preparation of our IPO.

(e) Other costs for the nine months ended September 30, 2021 consist of reimbursements paid to Providence for costs incurred prior to the IPO date and non-recurring recognition of a cease-use liability related to unoccupied leased office space. Other costs for the years ended December 31, 2020, 2019 and 2018 consist of reimbursements paid to Providence, and transaction costs related to the Providence Acquisition. For the nine months ended September 30, 2020, other costs include reimbursements paid to Providence

14

as well as costs related to the departure of our former Chief Executive Officer, and third-party costs incurred in response to investigating and remediating certain IT/cybersecurity matters that occurred in March 2020.

(f) Other (income) expense consists of interest income, changes in fair value associated with contingent considerations and the impact of foreign currency transaction gains and losses associated with monetary assets and liabilities.

We use Adjusted EBITDA and Adjusted EBITDA Margin as measures of operational efficiency to understand and evaluate our core business operations. We believe that these non-GAAP financial measures are useful to investors for period to period comparisons of our core business and for understanding and evaluating trends in our operating results on a consistent basis by excluding items that we do not believe are indicative of our core operating performance.

These non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as substitutes for an analysis of our results as reported under GAAP. Some of the limitations of these measures are:

● they do not reflect changes in, or cash requirements for, our working capital needs;

● Adjusted EBITDA does not reflect our capital expenditures or future requirements for capital expenditures or contractual commitments;

● they do not reflect income tax expense or the cash requirements to pay income taxes;

● they do not reflect our interest expense or the cash requirements necessary to service interest or principal payments on our debt; and

● although depreciation and amortization are non-cash charges related mainly to intangible assets, certain assets being depreciated and amortized will have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements.

In addition, other companies in our industry may calculate these non-GAAP financial measures differently than we do, limiting their usefulness as a comparative measure. You should compensate for these limitations by relying primarily on our GAAP results and using the non-GAAP financial measures only supplementally.

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should consider and read carefully all of the risks and uncertainties described below, as well as other information contained in this prospectus, including our consolidated financial statements and related notes appearing at the end of this prospectus, before making an investment decision. The risks described below are not the only ones facing us. The occurrence of any of the following risks or additional risks and uncertainties not presently known to us could materially and adversely affect our business, financial condition, results of operations or cash flows. In any such case, the trading price of our common stock could decline, and you may lose all or part of your investment. This prospectus also contains forward-looking statements and estimates that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of specific factors, including the risks and uncertainties described below.

Risks Relating to Our Business

If we fail to respond to technological developments or evolving industry standards, our solutions may become obsolete or less competitive.

Our future success will depend in part on our ability to develop new solutions and modify or enhance our existing platform in order to meet customer needs, add functionality and address technological advancements. To remain competitive, we will need to continuously upgrade our existing platform and develop new solutions that address evolving technologies and standards across all major channels, formats and devices for digital advertising, including mobile, social, video, in-app, display and connected television, as well as across digital media buying platforms, such as programmatic, direct ad exchanges and trading networks. We may be unsuccessful in upgrading our existing platform or identifying new solutions in a timely or cost-effective manner, or we may be limited in our ability to develop or market new or upgraded solutions due to patents held by others. In addition, any new product innovations may not achieve the market penetration or price levels necessary for profitability. Further, if our existing and future product offerings fail to maintain or achieve Media Rating Council (“MRC”) or other industry accreditation standards, customer acceptance of our products may decrease. If we are unable to develop timely enhancements to, and new features for, our existing platform or if we are unable to develop new solutions that align with advertiser demands as priorities shift or keep pace with rapid technological developments or changing industry standards, the solutions we deliver may become obsolete, less marketable and less competitive, and our business, financial condition and results of operations may be adversely affected.

The market in which we participate is highly competitive.

The market for measurement, data analytics and authentication of digital advertising is competitive and evolving rapidly. As this market evolves, competition may intensify as existing companies expand their businesses and new companies enter the market, which could lead to commoditization and harm our ability to increase revenue and maintain profitability. Our success depends on our ability to retain and grow our existing customers and sell our platform and solutions to new customers. If existing or new companies develop, market or offer competitive products, acquire one of our competitors or form a strategic alliance with one of our competitors or integration partners, our ability to attract new customers or retain existing customers could be adversely impacted and our results of operations could be harmed. Our current and potential competitors may have more financial, technical, marketing and other resources, as well as longer operating histories and greater name recognition than we do. As a result, these competitors may be better able to respond quickly to new technologies or devote greater resources to the development, promotion, sale and support of their products and services. We cannot assure you that our customers will continue to use our platform or that we will be able to replace, in a timely manner or at all, departing customers with new customers that generate comparable revenue.

We believe that our ability to compete successfully in our market depends on a number of factors, both within and outside of our control, including: (i) the price, quality and effectiveness of our solutions and those of our competitors; (ii) our ability to retain and add new integration partners; (iii) the timing and success of new product introductions; (iv) our position as an independent third-party within the digital advertising ecosystem; (v) the emergence of new technologies; (vi) the number and nature of our competitors; (vii) the protection of our intellectual property rights; (viii) the adoption of new privacy standards or regulations; and (ix) general market and economic conditions. The competitive environment could result in price reductions that could result in lower profits and loss of market share. If we are unable to compete successfully against our current and future competitors, we may not be able to retain and acquire customers and our business, financial condition and results of operations could be adversely affected.

16

System failures, security breaches, cyberattacks or natural disasters could interrupt the operation of our platform and data centers and significantly harm our business, financial condition and results of operations.

Our success depends on the efficient and uninterrupted operation of our platform. A failure of our computer systems, or those of our demand-side integration partners, could impede access to our platform, interfere with our data analytics, prevent the timely delivery of our solutions or damage our reputation. In the future, we may need to expand our systems at a significant cost and at a more rapid pace than we have to date. We may be unable to provide our solutions on a timely basis or experience performance issues with our platform if we fail to adequately expand or maintain our system capabilities to meet future requirements. Any disruption in our ability to operate our platform will prevent us from providing the solutions requested by our customers and partners, which may damage our reputation and result in the loss of customers or integration partners and the imposition of penalties or other legal or regulatory action, and our business, financial condition and results of operations could be adversely affected.

In delivering our solutions, we are dependent on the operation of our data centers, which are vulnerable to damage or interruption from earthquakes, terrorist attacks, war, floods, fires, power loss, telecommunications failures, computer viruses, computer denial of service attacks or other attempts to harm our system and similar events. Some of our systems are not fully redundant, and our disaster recovery planning cannot account for all eventualities. The occurrence of any issues or failures at our data centers could result in interruptions in the delivery of our solutions to our customers. For example, in March 2020, one of the third-party data centers we use experienced a fire that caused a temporary outage of certain services to some of our customers.

In addition, our ability to operate our platform and deliver our solutions may be interrupted by computer viruses, cyberattacks and security breaches. For example, unauthorized parties have in the past and may attempt in the future to gain access to our information systems. Outside parties have in the past and may also attempt in the future to fraudulently induce our employees or users of our platform to disclose sensitive information via illegal electronic spamming, phishing or other tactics. Any breach of our security measures or the accidental loss, inadvertent disclosure or unauthorized dissemination of proprietary information or sensitive, personal or confidential data about us, our employees or our customers or integration partners, including the potential loss or disclosure of such information or data as a result of hacking, fraud, trickery or other forms of deception, could expose us, our employees, our customers or our integration partners to risks of loss or misuse of this information. Any such breach, loss, disclosure or dissemination may also result in potential liability or fines, governmental inquiry or oversight, litigation or a loss of customer confidence, any of which could harm our business and damage our reputation, possibly impeding our ability to retain and attract new customers, and cause a material adverse effect on our operations and financial condition.

Certain of our third-party service providers and other vendors have access to portions of our IT system. Performance failures or acts of negligence by these service providers may cause material disruptions to our IT systems.

Our solutions rely on integrations with demand- and supply-side advertising platforms, ad servers and social platforms.

Our solutions necessitate that demand- and supply-side advertising platforms, ad servers and social platforms accept and integrate with our technology. We have formed partnerships with these platforms to integrate our technology with their software, allowing our customers to utilize our solutions wherever they purchase or place an ad. Some of these integration partners have significant market share in the segment in which they operate. We can make no assurances that our existing integration partners will continue to, or that potential new integration partners will agree to, integrate our solutions. We also cannot assure you that our customers will continue to use our solutions available on these digital media platforms or that our integration partners will not develop products that compete with us in the future. If our customers stopped using our solutions on these digital media platforms or if our integration partners decide to cease integrating our solutions, our business, financial condition and results of operations could be adversely affected.

In addition, we rely on our demand-side integration partners to report to us on the usage of our solutions on their platforms, as well as revenue generated on their platforms. Any financial or other difficulties our integration partners face may negatively impact our business, as a significant portion of our revenue depends on customers using our solutions on these digital media platforms, and we are unable to predict the nature and extent of any such impact. We exercise very little control over our integration partners, which increases our vulnerability to problems with the services they provide and our reliance upon them for accurate data and revenue reporting. Any errors, failures, interruptions or delays experienced in connection with our integration partners could adversely affect our business, reputation and financial condition.

17

Economic downturns and unstable market conditions, including as a result of the COVID-19 pandemic, could adversely affect our business, financial condition and results of operations.

Our business depends on the demand for digital advertising measurement and authentication and on the overall economic health of our customers and integration partners. There is no assurance the digital advertising market will experience the growth we anticipate. The health of the digital advertising market and the related measurement and authentication sector is affected by many factors. Economic downturns or unstable market conditions in the markets and geographies that we currently serve may cause our customers to decrease their advertising budgets or slow the growth of their digital ad spend, which could 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 for geo-political or other reasons in any of those countries could result in our investments not yielding the returns we anticipate.

The 2019 novel coronavirus (“COVID-19”) pandemic and related government mandates and restrictions have resulted in market and supply chain disruptions and a global economic slowdown, which have materially impacted demand for a broad variety of goods and services, and are also disrupting sales channels and marketing activities. The conditions caused by the COVID-19 pandemic may affect how our customers conduct their businesses and adversely affect our customers’ willingness to utilize our solutions and delay prospective customers’ purchasing decisions. Our customers may decrease their overall advertising budgets as a response to the economic uncertainty, a decline in their business activity, and other COVID-related impacts on their business or industry. In the third quarter of 2021, we saw ad spend for certain categories continue to be impacted, including consumer packaged goods and auto, in part due to global supply chain disruptions. While our facilities generally remain open, we are making extensive use of the work-from-home model at the moment and have begun the process of reopening certain of our offices in a phased manner. Remote working arrangements may expose us to increased security risk and privacy concerns and there may be heightened sensitivity from government regulators with respect to privacy compliance in the current environment. Over time, remote working arrangements may diminish the cohesiveness of our personnel teams and our ability to maintain our culture, both of which are critical to our success. Remote working arrangements may also adversely affect our ability to foster a creative environment, hire additional qualified personnel and retain existing key personnel, any of which could adversely affect our productivity and overall operations. In addition, our efforts to reopen our offices safely may not be successful, could expose our employees to health risks, and us to associated liability, and could incur additional costs. We may also have to close our offices again if the COVID-19 pandemic worsens and return to a work-from-home model. Our management team has been focusing additional time on planning for and mitigating the risks of the COVID-19 pandemic, including plans to reopen our offices, which may reduce the amount of time available for other initiatives. The long-term impacts, if any, of the global COVID-19 pandemic on our business are currently unknown and our business, financial condition and results of operations may be materially impacted.

For further discussion of the impact of the COVID-19 pandemic on our business and financial results, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Factors Affecting Our Performance — COVID-19.” To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this “Risk Factors” section.

We have completed several acquisitions in the past and may consummate additional acquisitions in the future, which may be difficult to integrate, disrupt our business, expose us to unanticipated liabilities, dilute stockholder value or divert management attention.

We have completed several strategic acquisitions, including of Meetrics in August 2021, Ad-Juster, Inc. in October 2019, Zentrick NV in February 2019 and Leiki, Ltd. in December 2018. In addition, we recently signed an agreement in November 2021 to acquire OpenSlate, which is expected to close before the end of the year. As part of our growth strategy, we regularly evaluate and may consummate additional acquisitions in the future to enhance our technology platform, expand our product offerings, broaden our geographic footprint, or for other strategic reasons. We also may evaluate and enter into discussions regarding an array of potential strategic investments, including acquiring complementary products or technologies. Our recent acquisitions and any future acquisitions or investments may result in unforeseen operating difficulties and expenditures. In particular, we may encounter difficulties integrating the business, technologies, products, personnel or operations of an acquired company, and we may have difficulty retaining the customers or employees of any acquired business due to changes in management and ownership. An acquisition may also disrupt our ongoing business, divert our resources and require significant management attention that would otherwise be available for ongoing growth and development of our business. Moreover, we cannot assure you that the anticipated

18

benefits of an acquisition or investment would be realized in a timely manner, if at all, or that we would not be exposed to unknown costs and liabilities. Acquisitions involve numerous risks, any of which could harm our business and financial performance, including:

● the difficulty of assimilating the operations and personnel of the acquired companies;

● the potential disruption of our business;

● the inability of our management to maximize our financial and strategic position by the successful incorporation of acquired technology into our platform;

● unanticipated liabilities associated with an acquisition, including (i) technology, intellectual property and infringement issues, (ii) employment, retirement or severance related claims, (iii) claims by or amounts owed to customers or suppliers, (iv) adverse tax consequences and (v) other legal disputes;

● difficulty maintaining uniform standards, controls, procedures and policies, with respect to accounting matters and otherwise;

● the potential loss of key personnel of acquired companies;

● the impairment of relationships with employees and customers as a result of changes in management and operational structure;

● increased indebtedness to finance the acquisition;

● entrance into new geographic markets that subjects us to different laws and regulations that may have an adverse impact on our business; and

● the diversion of management time and focus from operating our business to addressing acquisition integration challenges.

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 the incurrence or assumption 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 cannot assure you that we will continue to acquire businesses at attractive valuations or that we will complete future acquisitions at all.

We are subject to payment-related risks, and if our ability to accurately and timely collect payments is impaired, our business, financial condition and results of operations may be adversely affected.

We have a large and diverse customer and integration partner base. At any given time, one or more of our customers or partners may experience financial difficulty, file for bankruptcy protection or cease operations. Unfavorable economic and financial conditions could result in an increase in customer or partner financial difficulties which could adversely affect us. The direct impact on us could include reduced revenues and write-offs of accounts receivable and expenditures billable to customers, and if these effects were severe enough, the indirect impact could include impairments of intangible assets and reduced liquidity. Furthermore, the payment risks we face are heightened since (i) our programmatic and certain other partners collect payments from all of our advertiser customers utilizing their platform and remit to us such amounts on behalf of these advertiser customers and (ii) media agencies pay us on behalf of multiple customers who utilize them, each of whom are subject to independent billing and payment risks as well. Although no customer accounted for more than 10% of our revenue in 2020, two programmatic partner platforms collected approximately 12% each of our total revenue in 2020 on behalf of our advertiser customers using their platforms.

In addition, each of our customers and integration partners may have different payment methods and cycles. The timing of receipt of payment from our customers and integration partners may impact our cash flows and working capital.

Defects, errors or inaccuracies associated with our solutions could negatively impact our business, financial condition and results of operations.

The technology underlying our platform may contain material defects or errors. If the data analytics we deliver to our customers are inaccurate or perceived to be inaccurate, due to defects or errors in our technology, our business may be harmed. Any inaccuracy

19

or perceived inaccuracy in the solutions we provide could lead to consequences that adversely impact our business, financial condition and results of operations, including:

● loss of customers;

● the incurrence of substantial costs to correct any material defect or error;

● potential litigation;

● interruptions in the availability of our platform;

● diversion of development resources;

● loss of MRC or other industry accreditation;

● lost sales or delayed market acceptance of our solutions; and

● damage to our brand.

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

Our sales cycle, from initial contact to contract execution and implementation, is often long and time consuming. Our sales efforts involve educating our customers about the use, technical capabilities and benefits of our software platform. Some of our customers undertake an evaluation process that involves reviewing the offerings of our competitors in addition to our platform. As a result, it is difficult to predict when a prospective customer will decide to execute an agreement and begin generating revenue for us. Even if our sales efforts result in obtaining a new customer, under our usage-based pricing model for most of our solutions, the customer controls when and to what extent it uses our platform. As a result, we may not be able to add customers or generate revenue as quickly as we may expect, which could adversely affect, or limit, the predictability of, our growth.

We depend on our senior management team and other key personnel to manage our business effectively, and if we are unable to retain such key personnel or hire additional qualified personnel, our ability to compete could be harmed.

Our company is led by a strong management team that has extensive experience leading technology and digital marketing companies. Our success and future growth depend to a significant degree on the leadership, knowledge, skills and continued services of our senior management team and other key personnel. The loss of any of these persons could adversely affect our business.

Our future success also depends on our ability to retain, attract and motivate highly skilled technical, managerial, marketing and customer service personnel. We have doubled the size of our work force since 2017 to more than 750 employees and expect to continue to grow in the near term. We may incur significant costs to attract and retain qualified employees, including significant expenditures related to salaries and benefits and compensation expenses related to equity awards. New employees often require significant training and we may lose new or existing employees to our competitors or other companies before we realize the benefit of our investment in recruiting and training them. Competition for personnel is intense, particularly in the technology and software industries. A substantial majority of our employees work for us on an at-will basis, and we may experience a loss of productivity due to the departure of key personnel and the associated loss of institutional knowledge. Our inability to retain and attract the necessary personnel could adversely affect our business, financial condition and results of operations.

In addition, our international expansion has led to an increasing number of employees based in countries outside of North America. With 320 employees based outside North America as of November 1, 2021, we are exposed to a number of additional country-specific risks. See “We are exposed to the risks of operating internationally.”

Data privacy legislation and regulation on digital advertising and privacy and data protection may adversely affect our business.

There are a growing number of data privacy and protection laws and regulations in the digital advertising industry that apply to our business. We have dedicated, and expect to continue to dedicate, significant resources in our efforts to comply with such laws and regulations. For example, we have implemented policies and procedures to comply with applicable data privacy laws and regulations

20

and rely on contractual representations made to us by customers and partners that the information they provide to us and their use of our solutions do not violate these laws and regulations or their own privacy policies. However, the application, interpretation and enforcement of these laws and regulations are often uncertain and continue to evolve, particularly in the new and rapidly evolving industry in which we operate, and may be interpreted and applied inconsistently between states within a country or between countries, and our current policies and practices may be found not to comply. Additionally, if our customers and partners’ representations are false or inaccurate, or if our customers and partners do not otherwise comply with applicable privacy laws, we could face adverse publicity and possible legal or regulatory action. Conversely, our partners and communications services providers have adopted their own policies based on their own perceptions of legal requirements or other policy determinations, and these policies have in the past temporarily prevented us, and may again in the future prevent us, from operating on their platforms and possibly result in loss of business or litigation. Any perception of our practices, platform or solutions delivery as a violation of privacy rights may subject us to public criticism, loss of customers or partners, class action lawsuits, reputational harm, or investigations or claims by regulators, industry groups or other third parties, all of which could significantly disrupt our business and expose us to liability in ways that negatively affect our business, results of operations and financial condition.

In addition, U.S. and foreign governments have enacted or are considering enacting new legislation related to privacy, data protection, data security and digital advertising and we expect to see an increase in, or changes to, legislation and regulation that affects our industry. For example, the European Union’s (“EU”) General Data Protection Regulation (“GDPR”), which became effective on May 25, 2018, and has resulted and will continue to result in significantly greater compliance burdens and costs for companies with users and operations in the EU and European Economic Area (“EEA”). Under GDPR, fines of up to 20 million Euros or up to 4% of the annual global revenues of the infringing party, whichever is greater, can be imposed for violations. The GDPR imposes several stringent requirements for controllers and processors of personal data and could make it more difficult and/or more costly for us to use and share personal data. In addition, the California Consumer Privacy Act (“CCPA”), which went into effect on January 1, 2020, limits how we may collect and use personal data. The effects of the CCPA potentially are far-reaching and may require us to modify our data processing practices and policies and incur substantial compliance-related costs and expenses. In November 2020, California voters passed the California Privacy Rights and Enforcement Act (“CPRA”), which expands the CCPA with additional data privacy compliance requirements that go into effect on January 1, 2023 and may impact our business, and establishes a regulatory agency dedicated to enforcing those requirements. Other states have also recently introduced or enacted comprehensive consumer privacy laws that broadly protect personal data, including the right to opt out of targeted advertising and certain profiling activities, and more states are expected to follow. It remains unclear how various provisions of the CCPA, CPRA and other state laws will be interpreted and enforced. Further, the Children’s Online Privacy Protection Act (“COPPA”) applies to websites and other online services that are directed to children under thirteen (13) years of age and imposes certain restrictions on the collection, use and disclosure of personal information from these websites and online services. These and other data privacy laws and their interpretations continue to develop and may be inconsistent from jurisdiction to jurisdiction. Noncompliance with these laws could result in penalties or significant legal liability. Although we take reasonable efforts to comply with all applicable laws and regulations, there can be no assurance that we will not be subject to regulatory action, including fines, in the event of an incident. We or our third-party service providers could be adversely affected if legislation or regulations are expanded to require changes in our or our third-party service providers’ business practices or if governing jurisdictions interpret or implement their legislation or regulations in ways that negatively affect our or our third-party service providers’ business, results of operations or financial condition. These federal, state and foreign laws and regulations, which in some cases can be enforced by private parties in addition to government entities, are increasingly restricting the collection, processing and use of personal data.

These laws are constantly evolving and can be subject to significant change or interpretive application. We continue to monitor changes in laws and regulations, and the costs of compliance with, and the other burdens imposed by, these and other new laws or regulatory actions may increase our costs. In addition, failure to comply with these and other laws and regulations may result in, among other things, administrative enforcement actions and significant fines, class action lawsuits, significant legal fees, and civil or criminal liability. Any regulatory or civil action that is brought against us, even if unsuccessful, may distract our management’s attention, divert our resources, negatively affect our public image or reputation among our customers and partners and within our industry, and, consequently, harm our business, results of operations and financial condition.

Public criticism of digital advertising technology in the U.S. and internationally, including digital advertising on social media platforms, could adversely affect the demand for and use of our solutions.

Our business depends, in part, on the demand for digital advertising technology. The digital advertising industry has been and may in the future be subject to reputational harm, negative media attention and public complaint relating to, among other things, the alleged lack of transparency and anti-competitive behavior among advertising technology companies. This public criticism could

21

result in increased data privacy and anti- trust regulation in the digital advertising industry in the U.S. and internationally. In addition, our services are delivered in web browsers, mobile apps and other software environments where online advertising is displayed, and certain of these environments have announced future plans to phase out or end the use of cookies and other third-party tracking technology on their operating systems in order to provide more consumer privacy. While our core technology and solutions do not rely on persistent identifiers or cookie-based or cross-site tracking, these changes and other updates to software functionality in these environments could hurt our ability to effectively deliver our services and make them less effective if our services are restricted from operating. We have also experienced significant growth in social media-related revenues and generate significant revenue from the use of our solutions on social media platforms, which have been and may in the future be the subject of avoidance campaigns or similar events, including ad boycotts on Facebook and Twitter. Any change or decrease in the demand for digital advertising, including on social media platforms as a result of avoidance campaigns or similar events, may negatively affect the demand for and use of our solutions. If our customers significantly reduce or eliminate their digital ad spend in response to the public criticism of the digital advertising industry or its related effects, our business, financial condition and results of operations could be adversely affected.

The success of our business depends in large part on our ability to protect and enforce our intellectual property rights.

We rely on a combination of intellectual property rights in our business and rely on patent, copyright, service mark, trademark and trade secret laws, as well as confidentiality procedures and contractual restrictions, to establish and protect our proprietary rights, all of which provide limited protection. We endeavor to enter into agreements with our employees and contractors and with parties with whom we do business in order to limit access to and disclosure of our proprietary information. We cannot be certain that the steps we have taken will prevent unauthorized use of our technology or the reverse engineering of our technology. We cannot make assurances that any additional patents will be issued with respect to any of our pending or future patent applications, that any patents issued to us will provide adequate protection, or that any patents issued to us will not be challenged, invalidated, circumvented, or held to be unenforceable in actions against alleged infringers. Also, we cannot make assurances that any future trademark or service mark registrations will be issued with respect to pending or future applications or that any of our registered trademarks and service marks will be enforceable or provide adequate protection of our proprietary rights. In addition, the laws of some foreign countries where our platform is utilized do not protect our proprietary rights to the same extent as do the laws of the United States. A failure to protect our intellectual property rights in the U.S. or elsewhere could adversely affect our business, financial condition and results of operations.

An assertion from a third party that we are infringing its intellectual property rights, whether such assertion is valid or not, could subject us to costly and time-consuming litigation, expensive licenses or other impacts to our business.

There is significant intellectual property development activity in the measurement and authentication of digital ads. Third-party intellectual property rights may cover significant aspects of our technologies or business methods or block us from expanding our platform and delivering new solutions, and we cannot be certain that our current operations do not infringe the rights of a third party. We have received and may continue to receive allegations and/or claims from third parties that our technology infringes or violates such third parties’ intellectual property rights. The cost of defending against such claims, whether or not the claims have merit, is significant 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 may be obligated to indemnify our customers or partners in connection with any such litigation. Intellectual property claims could harm our relationships with our customers and deter future customers from buying our solutions or expose us to litigation. If we are found to infringe intellectual property rights, we could potentially be subject to injunctive or other relief that could affect our ability to provide our solutions. We may also be required to develop alternative non-infringing technology and may be unable to do so, or such development may require significant time and expense and may not be successful. In addition, 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, this may limit our platform and solutions, and we may be unable to compete effectively. Any of these results could adversely affect our business, financial condition and results of operations.

We are exposed to the risks of operating internationally.

Our international operations are important to our current and future strategy, growth and prospects. We currently have operations in numerous foreign countries, including the United Kingdom, Israel, Singapore, Australia, Brazil, Mexico, France, Germany, Finland, Belgium and Japan, and expect to continue to expand our operations internationally. Our international operations are subject to varying degrees of regulation in each of the jurisdictions in which our services are provided. Local laws and regulations, and their

22

interpretation and enforcement, differ significantly among those jurisdictions, and can change significantly over time. Some of the risks inherent in conducting business internationally include:

● the complexities and expense of complying with a wide variety of foreign and domestic laws and regulations applicable to international operations, including privacy and data protection laws and regulations, the U.S. Foreign Corrupt Practices Act and other applicable anti-corruption and anti- bribery laws;

● difficulties in staffing and managing international operations, including complex and costly hiring and termination requirements;

● reduced or varied protection for intellectual property rights in some countries;

● challenges caused by distance, language and cultural differences;

● political, social and economic instability abroad, terrorist attacks and security concerns;

● trade disruptions or political tensions between the U.S. and foreign countries;

● fluctuations in currency exchange rates;

● potentially adverse tax consequences and the complexities of foreign value-added taxes and the repatriation of earnings;

● increased accounting and reporting burdens and complexities; and

● difficulties and expenses associated with tailoring our platform and solutions to local markets as may be required by local customers, regulations and local industry organizations.

Furthermore, our operations in the UK could be impacted by the UK’s formal exit from the EU (“Brexit”). Although the UK and the EU have reached a trade agreement on the terms of their future cooperation, there is still significant uncertainty with respect to the implementation of the future relationship between the EU and the UK. Given the status of Brexit at this time, we are unable to predict the impact that it may have on our operations in both the UK and the EU. Among other things, we could experience lower growth in the region, increased foreign currency risk, greater restrictions on business with UK customers and increased regulatory complexity.

Additionally, our ability to manage our business and conduct our operations internationally requires considerable management attention and financial resources. We cannot be certain that the investments and additional resources required for establishing and maintaining operations in other countries will hold their value or produce desired levels of revenues or profitability. Any one or more of these factors could negatively impact our international operations and thus adversely affect our business, financial condition and results of operations.

Our use of “open source” software could subject our technology to general release or require us to re-engineer our platform, or subject us to litigation, which could harm our business, financial condition and results of operations.

Some of our technology incorporates so-called “open source” software, and we may incorporate additional open source software in the future. Open source software is generally licensed by its authors or other third parties under open source licenses, which typically do not provide for any representations, warranties or indemnity coverage by the licensor. Some of these licenses provide that combinations of open source software with a licensee’s proprietary software are subject to the open source license and require that the combination be made available to third parties in source code form or at no cost. Some open source licenses may also require the licensee to grant licenses under certain of its intellectual property to third parties. Additionally, there is little case law interpreting such licenses and there is a risk that open source licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to provide our platform. If a third party that distributes open source software were to allege that we had not complied with the conditions of one or more of these licenses, we could be required to incur significant legal expenses defending against such allegations and could be subject to significant damages, enjoined from the sale of our solutions that contain the open source software and required to comply with the foregoing conditions, which could disrupt the distribution and sale of some of our solutions. In addition, we may be forced to re-engineer our platform or discontinue use of certain open source software, and related

23

solutions provided by our platform that use such open source software. Any of these events could adversely affect our business, financial condition and results of operations.

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

Our revenue, cash flow, operating results and other key operating and performance metrics may vary from quarter to quarter due to the seasonal nature of our customers’ spending on advertising campaigns. For example, advertisers typically allocate the largest portion of their media budgets to the fourth quarter of the calendar year in order to coincide with increased holiday purchasing. As a result, the fourth quarter of the year typically reflects our highest level of measurement activity while the first quarter reflects the lowest level of such activity. 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 operating results from period to period.

We have a limited operating history, which makes it difficult to evaluate our business and prospects and may increase the risks associated with your investment.

Our business was founded in 2008 and, as a result, we have a limited operating history upon which our business and prospects may be evaluated. Although we have experienced substantial revenue growth in our limited operating history, we may not be able to sustain this rate of growth or maintain our current revenue levels. We have encountered and will continue to encounter risks and challenges frequently experienced by rapidly growing companies in developing industries, including risks related to our ability to:

● build a reputation for providing superior customer service and for creating trust and long-term relationships with our customers;

● distinguish ourselves from competitors;

● scale our business efficiently;

● maintain and expand our relationships with customers and partners;

● respond to evolving industry standards and government regulation that impact our business, particularly in the areas of data privacy;

● respond to technological advances;

● prevent or mitigate security failures or breaches;

● expand our business internationally; and

● hire and retain qualified employees.

We cannot assure you that we will be successful in addressing these and other challenges we may face in the future. If we are unable to do so, our business may suffer, our revenue and operating results may decline and we may not be able to achieve further growth or sustain profitability.

We are subject to taxation in multiple jurisdictions. Any adverse development in the tax laws of any of these jurisdictions or any disagreement with our tax positions could have a material and adverse effect on our business, financial condition or results of operations.

We are subject to taxation in, and to the tax laws and regulations of, multiple jurisdictions as a result of the international scope of our operations and our corporate entity structure. Adverse developments in these laws or regulations, or any change in position regarding the application, administration or interpretation thereof, in any applicable jurisdiction, could have a material and adverse effect on our business, financial condition or results of operations. In addition, the tax authorities in any applicable jurisdiction, including the U.S., may disagree with the positions we have taken or intend to take regarding the tax treatment or characterization of any of our transactions.

24

Our revenues and results of operations may fluctuate in the future. As a result, we may fail to meet the expectations of securities analysts or investors, which could cause our stock price to decline.

Our results of operations may fluctuate as a result of a variety of factors, many of which are outside of our control. If our revenues or results of operations do not meet the expectations of securities analysts or investors, the price of our common stock could decline. Factors that may cause fluctuations in our revenues or results of operations include:

● our ability to retain and grow relationships with existing customers and attract new customers;

● the loss of demand-side platforms as integration partners;

● the timing and success of new product introductions, including the introduction of new technologies or offerings, by us, our competitors or others in the advertising marketplace;

● changes in the pricing of our solutions or those of our competitors;

● our failure to accurately estimate or control costs, including those incurred as a result of investments, other business or product development initiatives and the integration of acquired businesses;

● the effects of acquisitions and their integration;

● changes and uncertainty in the regulatory environment;

● the amount and timing of capital expenditures and operating costs related to the maintenance and expansion of our operations and infrastructure;

● service outages, other technical difficulties or security breaches;

● limitations relating to the capacity of our networks, systems and processes;

● maintaining appropriate staffing levels and capabilities relative to projected growth, or retaining key personnel;

● the risks associated with operating internationally; and

● general economic, political, regulatory, industry and market conditions and those conditions specific to internet usage and digital media.

Based upon the factors above and others both within and beyond our control, we have a limited ability to forecast our future revenue, costs and expenses, and as a result, our operating results may, from time to time, fall below our estimates or the expectations of analysts and investors. We believe that our revenues and results of operations on a year-over-year and sequential quarter-over-quarter basis may vary significantly in the future. Investors are cautioned not to rely on the results of prior periods as an indication of future performance.

Our estimates of market opportunity and forecasts of market growth included in this prospectus may prove to be inaccurate.

Market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Our estimates and forecasts relating to the size and expected growth of our market may prove to be inaccurate. For example, the digital advertising industry may not grow at the rate that we currently expect, the migration of advertising from linear television to CTV may not occur on the scale we currently anticipate, or the growth of subscription media platforms as opposed to platforms supported by advertising may all impact the estimates and growth forecasts we have included in this prospectus. Even if the market in which we compete meets our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all.

25

Our financial condition and results of operations could be adversely affected if we incur an impairment of goodwill or other intangible and long-lived assets.

As of September 30, 2021, we had $244.7 million of goodwill and $136.7 million of other long-lived assets, including property, plant and equipment and intangible assets. We are required to test intangible assets and goodwill annually and on an interim basis if an event occurs or there is a change in circumstance that would more likely than not reduce the fair value below its carrying values or indicate that the carrying value of such intangibles is not recoverable. When the carrying value exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. If the carrying amount of an intangible asset is not recoverable, a charge to operations is recognized. Either event would result in incremental expenses for that period, which would reduce any earnings or increase any loss for the period in which the impairment was determined to have occurred.

Our impairment analysis is sensitive to changes in key assumptions used in our analysis, such as expected future cash flows. Additionally, changes in our strategy or significant technical developments could significantly impact the recoverability of our intangible assets. If the assumptions used in our analysis are not realized, it is possible that an impairment charge may need to be recorded in the future. We did not identify an impairment of goodwill or long-lived assets for the nine months ended September 30, 2021 or the years ended December 31, 2020 or 2019. We cannot predict the amount and timing of any future impairment of goodwill or other intangible assets.

See Note 4 to our audited consolidated financial statements included elsewhere in this prospectus for further discussion on the goodwill recognized from our recent acquisitions.

Restrictions in the New Revolving Credit Facility could adversely affect our business, financial condition and results of operations.

The operating and financial restrictions and covenants in the New Revolving Credit Facility, and any future financing agreements, could restrict the ability of DoubleVerify MidCo, Inc., DoubleVerify Inc. and their respective subsidiaries (the “Credit Group”) to finance future operations or capital needs or to expand or pursue the Credit Group’s business activities. The New Revolving Credit Facility contains limitations on the ability of the Credit Group to, among other things:

● pay dividends or purchase, redeem or retire capital stock;

● grant liens;

● incur or guarantee additional debt;

● make investments and acquisitions;

● enter into transactions with affiliates;

● enter into any merger, consolidation or amalgamation or dispose of all or substantially all property or business; and

● dispose of property, including issuing capital stock.

The New Revolving Credit Facility also contains covenants requiring the Credit Group to maintain certain financial ratios. The Credit Group’s ability to meet those financial ratios can be affected by events beyond our control, and we cannot assure you that the Credit Group will meet any such ratios in the future.

The New Revolving Credit Facility is secured by substantially all of the assets (subject to customary exceptions) of the Credit Group. A failure to comply with the provisions of the New Revolving Credit Facility could result in a default or an event of default that could enable our lenders to declare the outstanding principal amount of that debt, together with accrued and unpaid interest, to be immediately due and payable. We might not have, or be able to obtain, sufficient funds to make these accelerated payments. If the payment of our debt is accelerated and we do not have sufficient cash available to repay such indebtedness, the lenders could enforce their security interests and liquidate some or all of the secured assets of the Credit Group to repay the outstanding principal and interest, and our stockholders could experience a partial or total loss of their investment. For more information about the New Revolving Credit Facility, see “Description of Certain Indebtedness.”

26

In the future, we may need to obtain additional financing that may not be available or may reduce our profitability or result in dilution to our stockholders.

We may require additional capital in the future to develop and execute our long-term growth strategy. We believe the net proceeds from the IPO and the concurrent private placement and borrowings under the New Revolving Credit Facility, together with cash flows from operations, should be sufficient to fund our capital requirements for at least the next twelve months. However, we may need to raise additional funds in the future in order to, among other things:

● finance working capital requirements, capital investments or refinance existing or future indebtedness;

● acquire complementary businesses, technologies or products;

● develop or enhance our technological infrastructure and our existing platform and solutions;

● fund strategic relationships; and

● respond to competitive pressures.

If we incur additional indebtedness, our profitability may be reduced. Any future indebtedness could be at higher interest rates and may require us to comply with restrictive covenants, which could place limitations on our business operations. Further, we may not be able to maintain sufficient cash flows from our operating activities to service our existing and any future indebtedness. If our operating results are not sufficient to service any future indebtedness, we will be forced to take actions such as reducing or delaying our business activities, investments or capital expenditures, selling assets or issuing equity. If we issue additional equity securities, our stockholders may experience significant dilution and the price of our common stock may decline. Alternatively, if adequate funds are not available or are not available on acceptable terms, our ability to fund our strategic initiatives, take advantage of unanticipated opportunities, develop or enhance our technology or services or otherwise respond to competitive pressures could be significantly limited.

Risks Related to Our Common Stock and This Offering

The market price of our common stock may be volatile and could decline regardless of our operating performance.

The market price of our common stock may fluctuate significantly based on a number of factors that are outside of our control. Among the factors that could affect our stock price are:

● actual or anticipated fluctuations in our quarterly operating results;

● changes in securities analysts’ estimates of our financial performance or lack of research coverage and reports by industry analysts;

● actions by institutional stockholders or other large stockholders (including the Providence Investor), including future sales of our common stock;

● failure to meet any guidance given by us or any change in any guidance given by us, or changes by us in our guidance practices;

● industry, regulatory or general market conditions;

● domestic and international economic factors unrelated to our performance;

● changes in our customers’ or partners’ preferences;

● changes in law or regulation;

● lawsuits, enforcement actions and other claims by third parties or governmental authorities;

27

● adverse publicity related to us or another industry participant;

● announcements by us of significant impairment charges;

● speculation in the press or investment community;

● investor perception of us and our industry;

● changes in market valuations or earnings of similar companies;

● announcements by us or our competitors of significant contracts, acquisitions, dispositions or strategic partnerships;

● war, terrorist acts and epidemic disease;

● any future offerings of our common stock or other securities;

● additions or departures of key personnel; and

● misconduct or other improper actions of our employees.

In particular, we cannot assure you that you will be able to resell your shares at or above the public offering price. Stock markets have experienced extreme volatility in recent years that has been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock.

DoubleVerify is a holding company with no operations of its own, and it depends on its subsidiaries for cash to fund all of its operations and expenses, including to make future dividend payments, if any.

Our operations are conducted entirely through our subsidiaries, and our ability to generate cash to fund our operations and expenses, to pay dividends or to meet debt service obligations is highly dependent on the earnings and the receipt of funds from our subsidiaries through dividends or intercompany loans. Deterioration in the financial condition, earnings or cash flow of DoubleVerify and its subsidiaries for any reason could limit or impair their ability to pay such distributions. Additionally, to the extent our subsidiaries are restricted from making such distributions under applicable law or regulation or under the terms of our existing or future financing arrangements, or are otherwise unable to provide funds to the extent of our needs, there could be a material adverse effect on our business, financial condition or results of operations.

Future sales of shares by us or our existing stockholders could cause our stock price to decline.

Sales of substantial amounts of our common stock in the public market following this offering, or the perception that these sales could occur, could cause the market price of our common stock to decline. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

As of November 1, 2021, we had 158,629,136 outstanding shares of common stock. Following the completion of this offering, a portion of these shares will be immediately tradable without restriction under the Securities Act of 1933, as amended (the “Securities Act”), except for any shares held by “affiliates,” as that term is defined in Rule 144 under the Securities Act (“Rule 144”). We have filed a registration statement on Form S-8 under the Securities Act to register the shares of common stock to be issued under our equity compensation plans and, as a result, all shares of common stock acquired upon exercise of stock options or vesting of restricted stock units granted under these plans are also freely tradable under the Securities Act, subject to the terms of the lock-up agreements entered into in connection with this offering. As of November 1, 2021, there were stock options outstanding to purchase a total of 14,274,607 shares of our common stock and 2,696,762 outstanding restricted stock units (each restricted stock unit representing the right to receive one share of common stock upon vesting).

The remaining shares of common stock outstanding and held by our existing stockholders as of the completion of this offering will be restricted securities within the meaning of Rule 144, but will be eligible for resale subject to applicable volume, manner of sale, holding period and other limitations of Rule 144 or pursuant to an exemption from registration under Rule 701 under the Securities Act (“Rule 701”), subject to the lock-up agreements entered into in connection with this offering.

28

In connection with this offering, we, our executive officers and directors and the selling stockholders will agree, subject to certain exceptions described herein, not to sell, transfer or dispose of or hedge, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for shares of our common stock for a period of 90 days after the date of this prospectus, except with the prior written consent of J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC.

Following the expiration of the lock-up period described above, all such shares are expected to be eligible for future sale, subject to the applicable volume, manner of sale, holding period and other limitations of Rule 144 or pursuant to an exemption from registration under Rule 701. See “Shares Available for Future Sale” for a discussion of the shares of common stock that may be sold into the public market in the future. In addition, our significant stockholders may distribute shares that they hold to their investors who themselves may then sell into the public market following the expiration of the lock-up period. Such sales may not be subject to the volume, manner of sale, holding period and other limitations of Rule 144. The market price of our common stock could decline if the holders of those shares sell them or are perceived by the market as intending to sell them.

In the future, we may issue additional shares of common stock or other equity or debt securities convertible into or exercisable or exchangeable for shares of our common stock in connection with a financing, strategic investment, litigation settlement or employee arrangement or otherwise. Any of these issuances could result in substantial dilution to our existing stockholders and could cause the trading price of our common stock to decline.

If securities or industry analysts do not publish research or publish misleading or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more research analysts downgrades our stock or publishes misleading or unfavorable research about our business, our stock price would likely decline. If one or more of the analysts ceases coverage of our common stock or fails to publish reports on us regularly, demand for our common stock could decrease, which could cause our common stock price or trading volume to decline.

Providence has significant influence over us and may not always exercise its influence in a way that benefits our public stockholders.

Following the completion of this offering, the Providence Investor will own approximately 51.9% of the outstanding shares of our common stock (or approximately 51.1% if the underwriters exercise in full their option to purchase additional shares from the selling stockholders). As a result, Providence will continue to exercise significant influence over all matters requiring stockholder approval for the foreseeable future, including approval of significant corporate transactions, which may reduce the market price of our common stock.

Because Providence’s interests may differ from your interests, actions Providence takes as our controlling stockholder may not be favorable to you. For example, the concentration of ownership held by Providence could delay, defer or prevent a change of control of us or impede a merger, takeover or other business combination that another stockholder may otherwise view favorably. Other potential conflicts could arise, for example, over matters such as employee retention or recruiting, or our dividend policy.

Furthermore, as long as Providence continues to beneficially own a majority of our outstanding common stock, Providence generally will be able to determine the outcome of corporate actions requiring stockholder approval, including the election of the members of our board of directors and the approval of significant corporate transactions, such as mergers and the sale of substantially all of our assets. Even after Providence reduces its beneficial ownership below 50% of our outstanding common stock, it will likely still be able to assert significant influence over our board of directors and certain corporate actions. Following the completion of this offering, Providence will continue to have the right to designate for nomination for election one or more of our directors so long as it beneficially owns at least 5% of our common stock. See “Certain Relationships and Related Party Transactions — Relationship with Providence — Stockholders Agreements.”

Under our amended and restated certificate of incorporation, Providence and its affiliates and, in some circumstances, any of our directors and officers who is also a director, officer, employee, member or partner of Providence and its affiliates, have no obligation to offer us corporate opportunities.

The policies relating to corporate opportunities and transactions with Providence set forth in our second amended and restated certificate of incorporation (the “amended and restated certificate of incorporation”) addresses potential conflicts of interest between

29

DoubleVerify, on the one hand, and Providence and its officers, directors, employees, members or partners who are directors or officers of our company, on the other hand. In accordance with those policies, Providence may pursue corporate opportunities, including acquisition opportunities that may be complementary to our business, without offering those opportunities to us. By becoming a stockholder in DoubleVerify, you will be deemed to have notice of and to have consented to these provisions of our amended and restated certificate of incorporation. Although these provisions are designed to resolve conflicts between us and Providence and its affiliates fairly, conflicts may not be resolved in our favor or be resolved at all.

Future offerings of debt or equity securities which would rank senior to our common stock may adversely affect the market price of our common stock.

If, in the future, we decide to issue debt or equity securities that rank senior to our common stock, it is likely that such securities will be governed by an indenture or other instrument containing covenants restricting our operating flexibility. Additionally, any convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock and may result in dilution to owners of our common stock. We and, indirectly, our stockholders, will bear the cost of issuing and servicing such securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of any future offerings. Thus, holders of our common stock will bear the risk of our future offerings reducing the market price of our common stock or diluting their ownership stake in us.

Fulfilling our obligations incident to being a public company, including compliance with the Exchange Act and the requirements of the NYSE, the Sarbanes-Oxley Act and the Dodd-Frank Act, is expensive and time- consuming, and any delays or difficulties in satisfying these obligations could have a material adverse effect on our future results of operations and our stock price.

As a public company, we are subject to the reporting, accounting and corporate governance requirements of the NYSE, the Exchange Act, the Sarbanes-Oxley Act and Section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection, or the “Dodd-Frank Act,” that apply to issuers of listed equity, which impose certain significant compliance requirements, costs and obligations upon us. The changes necessitated by being a publicly listed company require a significant commitment of additional resources and management oversight which increase our operating costs. Further, to comply with the requirements of being a public company, we have undertaken various actions, such as implementing new internal controls and procedures and hiring additional accounting or internal audit staff. These laws and regulations also could make it more difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as our executive officers.

The expenses associated with being a public company include increases in auditing, accounting and legal fees and expenses, investor relations expenses, increased directors’ fees and director and officer liability insurance costs, registrar and transfer agent fees and listing fees, as well as other expenses. As a public company, we are required, among other things, to define and expand the roles and the duties of our board of directors and its committees and institute more comprehensive compliance and investor relations functions. Failure to comply with the requirements of being a public company could potentially subject us to sanctions or investigations by the SEC, the NYSE or other regulatory authorities, delisting of our common stock, and potentially civil litigation.

We have identified material weaknesses in our internal control over financial reporting related to our control environment. If our remediation of the material weaknesses is not effective, or if we fail to maintain an effective system of internal control over financial reporting in the future, our ability to timely and accurately report our financial condition or results of operations could be impaired, which may adversely affect investor confidence in us and the value of our common stock may be negatively affected.

As a public company, we are required to comply with the rules of the SEC implementing Section 404 of the Sarbanes-Oxley Act. Beginning with our annual report on Form 10-K for the year ended December 31, 2022, we will be required to provide an annual management report on the effectiveness of our internal control over financial reporting. However, our independent registered public accounting firm is not required to attest to the effectiveness of our internal control over financial reporting until after we are no longer an “emerging growth company” as defined in the JOBS Act. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our internal control over financial reporting is documented, designed, or operating. Any failure to implement and maintain effective disclosure controls and internal control over financial reporting could have a material and adverse effect on our business, financial condition and operating results, and cause a decline in the market price of our common stock.

30

During the course of preparing for our IPO, we identified a number of deficiencies related to the design and operating effectiveness of internal controls constituting material weaknesses in our control environment. Certain of those deficiencies relate to insufficient management review controls and lack of resources with an appropriate level of technical accounting knowledge that are relevant to the preparation and review of the Company’s consolidated financial statements, which constituted material weaknesses in our system of internal control. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis.

We are currently in the process of remediating the above material weaknesses, but there can be no assurance as to whether the remediation plan, as currently designed, will adequately remediate the material weaknesses. We have taken numerous steps to enhance our internal control environment by hiring additional finance and accounting personnel with prior experience working for finance departments of public companies and technical accounting experience, supplemented by third-party resources and external advisors; preparing accounting memoranda to address significant accounting transactions and other technical accounting and financial reporting matters; and improving our monitoring controls in the financial statement close and reporting process. While we believe these efforts improved our internal control over financial reporting, completion of these remediation measures will not provide assurance that our remediated controls will continue to operate properly or will be sufficient to prevent future material weaknesses or other deficiencies from occurring. There is no assurance that we will not identify additional material weaknesses in our internal control over financial reporting in the future.

If we do not effectively remediate these material weaknesses in our control environment, if we identify future material weaknesses in our internal control over financial reporting, or if we are unable to comply with the demands that are placed upon us as a public company, including the requirements of Section 404 of the Sarbanes-Oxley Act, in a timely manner, we may be unable to accurately report our financial results, or report them within the timeframes required by the SEC, resulting in reputational harm, distractions to management and our board of directors or disruptions to our business, a loss in confidence by investors in the reliability of our financial statements or restricted access to the capital markets, any of which could negatively impact our stock price. We also could become subject to sanctions or investigations by the NYSE, the SEC or other regulatory authorities. In addition, if we are unable to assert that our internal control over financial reporting is effective, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, when required, investors may lose confidence in the accuracy and completeness of our financial reports and our stock price may be adversely affected.

Anti-takeover provisions in our amended and restated certificate of incorporation and amended and restated bylaws could discourage, delay or prevent a change of control of our company and may affect the trading price of our common stock.

Our amended and restated certificate of incorporation and our amended and restated bylaws (the “amended and restated bylaws”) include a number of provisions that may discourage, delay or prevent a change in our management or control over us that stockholders may consider favorable. For example, our amended and restated certificate of incorporation and amended and restated bylaws collectively:

● authorize the issuance of “blank check” preferred stock that could be issued by our board of directors to thwart a takeover attempt;

● provide for a classified board of directors, which divides our board of directors into three classes, with members of each class serving staggered three-year terms, which prevents stockholders from electing an entirely new board of directors at an annual meeting;

● limit the ability of stockholders to remove directors if Providence ceases to beneficially own at least 40% of the outstanding shares of our common stock;

● provide that vacancies on our board of directors, including vacancies resulting from an enlargement of our board of directors, may be filled only by a majority vote of directors then in office;

● prohibit stockholders from calling special meetings of stockholders if Providence ceases to beneficially own at least 40% of the outstanding shares of our common stock;

31

● prohibit stockholder action by written consent, thereby requiring all actions to be taken at a meeting of the stockholders, if Providence ceases to beneficially own at least 40% of the outstanding shares of our common stock;

● establish advance notice requirements for nominations of candidates for election as directors or to bring other business before an annual meeting of our stockholders; and

● require the approval of holders of at least 662∕3% in voting power of the outstanding shares of our capital stock to amend our amended and restated bylaws and certain provisions of our amended and restated certificate of incorporation if Providence ceases to beneficially own at least 40% of the outstanding shares of our common stock.

These provisions may prevent our stockholders from receiving the benefit from any premium to the market price of our common stock offered by a bidder in a takeover context. Even in the absence of a takeover attempt, the existence of these provisions may adversely affect the prevailing market price of our common stock if the provisions are viewed as discouraging takeover attempts in the future. See “Description of Capital Stock — Anti-Takeover Effects of Our Certificate of Incorporation and Bylaws.”

Our amended and restated certificate of incorporation and amended and restated bylaws may also make it difficult for stockholders to replace or remove our management. Furthermore, the existence of the foregoing provisions, as well as the significant amount of common stock that Providence will continue to own following this offering, could limit the price that investors might be willing to pay in the future for shares of our common stock. These provisions may facilitate management entrenchment that may delay, deter, render more difficult or prevent a change in our control, which may not be in the best interests of our stockholders.

We could be the subject of securities class action litigation due to future stock price volatility, which could divert management’s attention and materially and adversely affect our business, financial condition, results of operations or cash flows.

The stock market in general, and market prices for the securities of companies like ours in particular, have from time to time experienced volatility that often has been unrelated to the operating performance of the underlying companies. A certain degree of stock price volatility can be attributed to being a newly public company. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating performance. In certain situations in which the market price of a stock has been volatile, holders of that stock have instituted securities class action litigation against the company that issued the stock. If any of our stockholders were to bring a similar lawsuit against us, the defense and disposition of the lawsuit could be costly and divert the time and attention of our management and could materially and adversely affect our business, financial condition, results of operations or cash flows.

We do not intend to pay dividends on our common stock for the foreseeable future and, consequently, your ability to achieve a return on your investment depends on appreciation in the price of our common stock.

We do not intend to declare and pay dividends on our common stock for the foreseeable future. We currently intend to use our future earnings, if any, to fund our growth, including through acquisitions, and for working capital needs and general corporate purposes. Therefore, you are not likely to receive any dividends on your common stock for the foreseeable future, and the success of an investment in shares of our common stock depends upon any future appreciation in their value. There is no guarantee that shares of our common stock will appreciate in value or even maintain the price at which our stockholders have purchased their shares. Payments of dividends, if any, are at the sole discretion of our board of directors after taking into account various factors, including general and economic conditions, our financial condition and operating results, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications of the payment of dividends by us to our stockholders or by our subsidiaries to us, and such other factors as our board of directors may deem relevant. In addition, our operations are conducted almost entirely through our subsidiaries. As such, to the extent that we determine in the future to pay dividends on our common stock, we will rely on our subsidiaries to make funds available to us for the payment of dividends. Further, the New Revolving Credit Facility limits the ability of our subsidiaries to pay dividends or otherwise transfer assets to us. In addition, Delaware law imposes additional requirements that may restrict our ability to pay dividends to holders of our common stock.

We are an emerging growth company, and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an emerging growth company, as defined in the JOBS Act. For as long as we remain an emerging growth company, we may take advantage of specified reduced reporting and other reduced requirements that are otherwise applicable generally to public

32

companies. In addition, under the JOBS Act, emerging growth companies can also delay adopting new or revised financial accounting standards until such time as those standards would otherwise apply to private companies. We took advantage of many of the reduced burdens during the course of the confidential submission and filing process with the SEC in connection with our IPO and expect to continue to take advantage of some or all of these reduced burdens and, as such, the information that we provide stockholders may be different from information you may receive from other public companies in which you hold equity interests. We do not know if some investors will find our common stock less attractive as a result of our utilization of these exemptions. The result may be a less active trading market for our common stock and increased volatility in the price of our common stock.

We are a “controlled company” within the meaning of NYSE rules and, as a result, we qualify for, and currently rely on, exemptions from certain corporate governance requirements. You will not have the same protections afforded to stockholders of companies that are subject to such requirements.

After the completion of this offering, Providence is expected to continue to control a majority of the voting power of our outstanding common stock. Accordingly, we expect to continue to qualify as a “controlled company” within the meaning of NYSE corporate governance standards. Under NYSE rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain NYSE corporate governance standards, including:

● the requirement that a majority of the board of directors consist of independent directors;

● the requirement that our Nominating and Corporate Governance Committee be composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities;

● the requirement that we have a Compensation Committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and

● the requirement for an annual performance evaluation of the Nominating and Corporate Governance and Compensation Committees.

Following this offering, we intend to continue to utilize many of these exemptions. As a result, we will not have a majority of independent directors, our Nominating and Corporate Governance and Compensation Committees will not consist entirely of independent directors and such committees may not be subject to annual performance evaluations. Additionally, we are only required to have all independent audit committee members within one year from the date of listing of our common stock on the NYSE. Consequently, you will not have the same protections afforded to stockholders of companies that are subject to all of the NYSE corporate governance rules and requirements. Our status as a controlled company could make our common stock less attractive to some investors or otherwise harm our stock price.

At such time as Providence no longer controls a majority of the voting power of our outstanding common stock, we will no longer be a “controlled company” within the meaning of NYSE rules. However, we may continue to rely on exemptions from certain corporate governance requirements during a one-year transition period.

At such time as Providence no longer controls a majority of the voting power of our outstanding common stock, we will no longer be a “controlled company” within the meaning of NYSE corporate governance standards. NYSE rules require that we (i) have a majority of independent directors on our board of directors within one year of the date we no longer qualify as a “controlled company”, (ii) have at least one independent director on each of the Compensation and Nominating and Corporate Governance Committees on the date we no longer qualify as a “controlled company,” at least a majority of independent directors on each of the Compensation and Nominating and Corporate Governance Committees within 90 days of such date and the Compensation and Nominating and Corporate Governance Committees composed entirely of independent directors within one year of such date, and (iii) perform an annual performance evaluation of the Nominating and Corporate Governance and Compensation Committees. During this transition period, we may continue to utilize the available exemptions from certain corporate governance requirements as permitted by NYSE rules. Accordingly, during the transition period you will not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the NYSE.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or stockholders.

Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our current or former directors, officers, other employees, agents or stockholders, (iii) any action or proceeding asserting a claim arising out of or under the Delaware General Corporation Law (the “DGCL”), or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware (including, without limitation, any action asserting a claim arising out of or pursuant to our amended and restated certificate of incorporation or our amended and restated bylaws) or (iv) any action or proceeding asserting a claim that is governed by the internal affairs doctrine, in each case, subject to such Court of Chancery of the State of Delaware having personal jurisdiction over the indispensable parties named as defendants; provided that, the exclusive forum provision will not apply to any action or proceeding brought to enforce any liability or duty created by the Exchange Act or any other action or proceeding asserting a claim for which the federal courts have exclusive jurisdiction; provided further that, if and only if the Court of Chancery of the State of Delaware dismisses any such action or proceeding for lack of subject matter jurisdiction, such action or proceeding may be brought in another state or federal court sitting in the State of Delaware. Accordingly, the exclusive forum provision does not relieve us of our duties to comply with the federal securities laws and the rules and regulations thereunder, and our stockholders are not deemed to have waived our compliance with these laws, rules and regulations. Unless the Company consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any claim arising under the Securities Act. By becoming a stockholder in our company, you will be deemed to have notice of and have consented to the provisions of our amended and restated certificate of incorporation related to choice of forum, provided that, if and only if the Court of Chancery of the State of Delaware dismisses any such action for lack of subject matter jurisdiction, such action may be brought in another state or federal court sitting in the State of Delaware. The choice of forum provision in our amended and restated certificate of incorporation may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or any of our directors, officers, other employees, agents or stockholders, which may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our amended and restated 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 materially and adversely affect our business, financial condition or results of operations.

Our amended and restated certificate of incorporation includes provisions limiting the personal liability of our directors for breaches of fiduciary duty under the DGCL.

Our amended and restated certificate of incorporation contains provisions eliminating a director’s personal liability to the fullest extent permitted by the DGCL for monetary damages resulting from a breach of fiduciary duty, except in circumstances involving:

● any breach of the director’s duty of loyalty;

● acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law;

● under Section 174 of the DGCL (unlawful dividends); or

● any transaction from which the director derives an improper personal benefit.

The principal effect of the limitation on liability provision is that a stockholder will be unable to prosecute an action for monetary damages against a director unless the stockholder can demonstrate a basis for liability for which indemnification is not available under the DGCL. These provisions, however, should not limit or eliminate our rights or any stockholder’s rights to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of a director’s fiduciary duty. These provisions do not alter a director’s liability under federal securities laws. The inclusion of this provision in our amended and restated certificate of incorporation may discourage or deter stockholders or management from bringing a lawsuit against directors for a breach of their fiduciary duties, even though such an action, if successful, might otherwise have benefited us and our stockholders.

Company Overview

We are a leading software platform for digital media measurement and analytics. Our mission is to increase the effectiveness and transparency of the digital advertising ecosystem. Through our software platform and the metrics it provides, we help preserve the fair value exchange in the digital advertising marketplace.

Our customers include many of the largest global advertisers and digital ad platforms and publishers. We deliver our suite of measurement solutions through a robust and scalable software platform that provides our customers with unified data analytics. We provide a consistent, cross-platform measurement standard across all major forms of digital media, making it easier for advertiser and supply-side customers to benchmark performance across all of their digital ads and to optimize their digital strategies in real time. Our coverage spans over 40 key geographies where our customers are located and covers all major purchasing channels, media formats and devices.

Our company was founded in 2008 and introduced our first brand safety solution in 2010. We launched our first viewability and fraud solutions in 2013 and 2014, respectively. As the global digital advertising market has evolved, we have continued to expand our measurement capabilities and market coverage through new product innovation, increasing our international footprint and new platform partnerships. We announced our first social media platform partnership in 2017 and launched our CTV certification program in 2020.

We have experienced rapid growth and have achieved significant profitability in recent years as evidenced by the following:

● We generated revenue of $227.2 million for the nine months ended September 30, 2021 and $165.3 million for the nine months ended September 30, 2020, representing an increase of 37%. We generated revenue of $243.9 million for the year ended December 31, 2020 and $182.7 million for the year ended December 31, 2019, representing an increase of 34%. We generated revenue of $182.7 million for the year ended December 31, 2019 and $104.3 million for the year ended December 31, 2018, representing an increase of 75%.

● Excluding the impact of acquisitions, we grew revenue 32% for the year ended December 31, 2020 relative to revenue for the year ended December 31, 2019, and we grew revenue 71% for the year ended December 31, 2019 relative to the revenue for the year ended December 31, 2018.

● Our net income was $1.0 million for the nine months ended September 30, 2021 and $12.3 million for the nine months ended September 30, 2020. Our net income was $20.5 million for the year ended December 31, 2020 and $23.3 million for the year ended December 31, 2019. Our net income was $23.3 million for the year ended December 31, 2019 and $3.2 million for the year ended December 31, 2018.

● Our Adjusted EBITDA was $69.3 million for the nine months ended September 30, 2021 and $45.6 million for the nine months ended September 30, 2020. Our Adjusted EBITDA was $73.2 million for the year ended December 31, 2020, $69.0 million for the year ended December 31, 2019 and $26.6 million for the year ended December 31, 2018. Adjusted EBITDA is a non-GAAP financial measure. For information on how we compute Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income, see “Prospectus Summary — Summary Historical Consolidated Financial Data.”

For the nine months ended September 30, 2021 and the year ended December 31, 2020, we generated 91% of our revenue from advertiser customers and for the year ended December 31, 2019, we generated 92% of our revenue from advertisers. We derive revenue from our advertising customers based on the volume of Media Transactions Measured on our software platform. Advertisers

40

utilize the DV Authentic Ad, our definitive metric of digital media quality, to evaluate the existence of fraud, brand safety, viewability and geography for each digital ad. Advertisers pay us a Measured Transaction Fee per thousand impressions based on the volume of Media Transactions Measured on their behalf. We maintain an expansive set of direct integrations across the entire digital advertising ecosystem, including with leading programmatic and social platforms, which enables us to deliver our metrics to the platforms where our customers buy ads. Further, our services are not reliant on any single source of impressions and we can service our customers as their digital advertising needs change. In 2020, approximately 65% and 35% of Media Transactions Measured were for display and video ad formats, respectively. For the year ended December 31, 2020, approximately 65%, 32% and 3% of Media Transactions Measured were for mobile devices, desktop devices, and emerging digital channels (including CTV), respectively. In 2019, approximately 69% and 31% of Media Transactions Measured were for display and video ad formats, respectively. For the year ended December 31, 2019, approximately 61%, 36% and 3% of Media Transactions Measured were for mobile devices, desktop devices, and emerging digital channels (including CTV), respectively. For the nine months ended September 30, 2021 and the year ended December 31, 2020, 9% of our revenue was generated from our supply-side customers and for the year ended December 31, 2019, 8% of our revenue was generated from our supply-side customers to validate the quality of their ad inventory. We generate revenue from supply-side customers based on monthly or annual contracts with minimum guarantees and tiered pricing when guarantees are met.

We believe that there are meaningful long-term growth opportunities within the digital advertising market. We plan to continue to invest in the development of new and premium solutions that increase our value proposition to customers and to extend our solutions capabilities to cover new and growing digital channels and devices, including CTV, new mobile apps and other emerging areas of digital ad spend. We plan to continue to invest in sales and marketing to grow our existing customer relationships and acquire new customers. In addition, we maintain an active pipeline of potential M&A targets and intend to continue evaluating add-on opportunities to bolster our current solutions suite and complement our organic growth initiatives.

Furthermore, we believe that there are significant growth opportunities in markets outside of North America. We plan to continue to invest in sales and marketing to expand in markets across Europe and the Middle East, Asia Pacific, and South America. We expect to continue to make investments across information technology, financial and administrative systems and controls to support our operations as we grow.

Factors Affecting Our Performance

There are a number of factors that have impacted, and we believe will continue to impact, our results of operations and growth. These factors include:

Significant Growth in Digital Ad Spend. According to Magna Global, global digital ad spend, excluding search, reached over $170 billion in 2020 and is expected to grow to $225 billion by 2023. Our revenues have grown substantially as a result of the growth in digital advertising as well as the continued adoption of digital measurement solutions and analytics. As the digital advertising market has grown, advertisers have increasingly shifted their digital media spend to both programmatic and social media channels in order to directly target advertisements to achieve desired business outcomes. We have been direct beneficiaries of this growth by virtue of our integrations with leading programmatic and social media platforms. In the year ended December 31, 2020, the revenue we generated by providing our solutions to programmatic and social media advertisers grew 39% and 42%, respectively, over the prior year period. In the year ended December 31, 2019, the revenue we generated by providing our solutions to programmatic and social media advertisers grew 127% and 162%, respectively, over the prior year period.

Growth of Existing Customers. Our customers include many of the largest digital advertisers in the world and we have maintained exceptional customer retention with gross revenue retention rates of over 95% in each of the years ended December 31, 2020, 2019 and 2018. We define our gross revenue retention rate as the total prior year revenue earned from advertiser customers, less the portion of prior year revenue attributable to lost advertiser customers, divided by the total prior year revenue from advertiser customers, excluding a portion of our revenues that cannot be allocated to specific advertiser customers. We expect to continue to grow with our existing customers as they increase their spend on digital advertising and as we introduce new solutions across key channels, formats, devices and geographies. We have generated strong historical net revenue retention rates, with 123% for the year ended December 31, 2020, 156% for the year ended December 31, 2019 and 131% for the year ended December 31, 2018. We define our net revenue retention rate as the total current period revenue earned from advertiser customers, which were also customers during the entire most recent twelve-month period, divided by the total prior year period revenue earned from the same advertiser customers, excluding a portion of our revenues that cannot be allocated to specific advertiser customers.

41

New Customers. We expect the increasing demand for third-party digital advertising data analytics to fuel continued adoption of our solutions. We estimate that in 2020 the total addressable market for our core solutions was approximately $13 billion globally and was less than 25% penetrated and is expected to grow to approximately $20 billion by 2025 with less than 50% penetration. Given the size of this currently underserved market, we believe there is a long runway of new customer growth, as advertisers, programmatic platforms, social media channels and digital publishers are collectively placing increased emphasis on the quality and effectiveness of digital ad spend across all channels, formats and devices. We intend to continue targeting new customers who have not yet adopted digital ad measurement solutions, as well as those currently utilizing solutions provided by our competitors or point solutions.

New Solutions and Channels. We have a strong track record of developing new solutions that have high adoption rates with our existing customers. We intend to extend our solutions capabilities to cover new and growing digital channels and devices, including CTV, new mobile apps and other emerging areas of digital ad spend. At the end of 2018, we launched our Authentic Brand Safety solution that allows our customers to target certain contexts for their ads using granular brand safety parameters and significantly reduce wasted ad spend, which drove $19.8 million of new revenue in 2019. In 2020, we developed and launched several new solutions: (i) our CTV Targeting Certification for programmatic platforms, (ii) the DV Publisher Suite that offers yield improvement and measurement capabilities to digital publishers, (iii) our DV Authentic Attention solution that provides exposure and engagement predictive analytics to drive campaign performance, which was developed in 2020 and released in February 2021, and (iv) our Custom Contextual solution, which allows advertisers to match their ads to relevant content in order to maximize user engagement and drive campaign performance, without depending on cookie-based or cross-site tracking.

New Geographies. Our customer base is predominately U.S.-based today. We intend to grow our presence in international markets in order to meet the needs of our existing customers and accelerate new customer acquisition in key geographies outside of North America. We have expanded into eighteen countries since 2018, which has accelerated our revenue growth in those markets. Our expansion to new geographies has helped us to win the international business of our existing customers and enabled us to win the business of some of the world’s largest international advertisers.

Seasonality. We experience fluctuations in revenue that coincide with seasonal fluctuations in the digital ad spending of our customers. Advertisers typically allocate the largest portion of their media budgets to the fourth quarter of the calendar year in order to coincide with increased holiday purchasing. As a result, the fourth quarter of the year typically reflects our highest level of measurement activity while 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. While our revenue is highly recurring, seasonal fluctuations in ad spend may impact quarter-over-quarter results. We believe that the year-over- year comparison of results more appropriately reflects the overall performance of the business.

Public Company Costs. As a result of our IPO, we have incurred, and will continue to incur, additional legal, accounting and other expenses that we did not previously incur, including costs associated with SEC reporting and corporate governance requirements. These requirements include compliance with the Sarbanes- Oxley Act as well as other rules implemented by the SEC and the NYSE. Our financial statements following our IPO reflect the impact of these expenses.

COVID-19. Since January 2020, an outbreak of COVID-19 has evolved into a worldwide pandemic. We have modified our operations in line with our business continuity plans. While our facilities generally remain open, we are making extensive use of the work-from-home model at the moment and have begun the process of reopening certain of our offices in a phased manner. Management is reviewing operations on a daily basis and there have been minimal interruptions in our customer facing operations to date.

Throughout the pandemic, we have continued to experience revenue growth over the prior year and the primary impact of the pandemic on our business has been a moderation of our revenue growth in 2020 as compared to 2019. The underlying demand for our products has remained relatively unchanged, with limited disruption on our new customer sales. We have not to date experienced a material increase in customers’ cancellations, or requests for more favorable contractual terms, or concessions. We have also not experienced a significant deterioration in the collectability of our receivables or a material negative impact from our vendors and third-party service providers.

For the year ended December 31, 2020, we generated growth of 34% in total revenue as compared to the year ended December 31, 2019. For the three months ended June 30, 2020, when the impact of COVID-19 was the most acute on our business, we generated revenue growth of 22% as compared to the three months ended June 30, 2019 and $4.1 million of net income. Our ability to grow revenue within our existing customer accounts has remained strong, with a net revenue retention of 123% for the year

42

ended December 31, 2020. Our existing customer base has remained largely stable, and our gross revenue retention rate was over 95% for the three months ended September 30, 2021 and the year ended December 31, 2020. Additionally, we generated net cash provided by operating activities of $58.4 million and $21.2 million in those same periods, respectively. We have had ample liquidity and capital resources to continue to meet our operating needs, and our ability to continue to service our debt or other financial obligations is not currently impaired.

While the impact on our business of the pandemic has been limited to date, our revenues are dependent on advertiser demand. The pandemic has resulted in market and supply chain disruptions and a global economic slowdown, which has materially impacted demand for a broad variety of goods and services, and is also disrupting sales channels and marketing activities. To the extent that demand for digital advertising declines, our results of operations and financial condition may be materially impacted. The duration of such disruptions is highly uncertain and cannot be predicted. See “Risk Factors — Risks Relating to Our Business — Economic downturns and unstable market conditions, including as a result of the COVID-19 pandemic, could adversely affect our business, financial condition and results of operations.”

While the factors above may present significant opportunities for us, they also pose significant risks and challenges. See “Risk Factors” for more information on risks and uncertainties that may impact our business and financial results.

Components of Our Results of Operations

We manage our business operations and report our financial results in a single segment.

Revenue

Our customers use our solutions to measure their digital advertisements. We generate revenue from our advertising customers based on the volume of Media Transactions Measured on our software platform and from supply-side customers based on contracts with minimum guarantees or contracts that have tiered pricing after minimum guarantees are achieved.

For the nine months ended September 30, 2021 and the years ended December 31, 2020 and 2019, we generated 91%, 91% and 92%, respectively, of our revenue from advertiser customers. Advertisers can purchase our services to measure the quality and performance of ads purchased directly from digital properties, including publishers and social media platforms, which we track as Advertiser Direct revenue. Advertisers can also purchase our services through programmatic platforms to evaluate the quality of ad inventories before they are purchased, which we track as Advertiser Programmatic revenue. We generate revenue from advertisers by charging a Measured Transaction Fee based on the volume of Media Transactions Measured on behalf of our customers. We recognize revenue from advertisers in the period in which we provide our measurement solutions. Advertisers typically leverage the full suite of our proprietary DV Authentic Ad metric to evaluate and measure the existence of fraud, brand safety, viewability and geography for their digital ad investments. We have long-term relationships with many of our customers, with an average relationship of almost six years for our top 75 customers and almost seven years for our top 25 customers, and ongoing contractual agreements with a substantial portion of our customer base.

For the nine months ended September 30, 2021 and the years ended December 31, 2020 and 2019, we generated 9%, 9% and 8%, respectively, of our revenue from supply-side customers who use our data analytics to validate the quality of their ad inventory and provide data to their customers to facilitate targeting and purchasing digital ads. We generate revenue from supply-side customers based on monthly or annual contracts with minimum guarantees and certain customers having tiered pricing when guarantees are met. We recognize revenue ratably over the contract term beginning on the date our product is made available to them, which typically begins on the commencement date of each contract.

Operating Expenses

Our operating expenses consist of the following categories:

Cost of revenue. Cost of revenue primarily consists of platform hosting fees, data center costs, software and other technology expenses, and other costs directly associated with data infrastructure; personnel costs, including salaries, bonuses, stock-based compensation and benefits, directly associated with the support and delivery of our software platform and data solutions; and costs from revenue-sharing arrangements with our partners.

Product development. Product development expenses primarily consist of personnel costs, including salaries, bonuses, stock-based compensation and benefits, third party vendors and outsourced engineering services, and allocated overhead. We allocate overhead such as information technology infrastructure, rent and occupancy charges based on headcount. Product development expenses 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 property, plant and equipment on our consolidated balance sheet. We amortize capitalized software development costs to depreciation and amortization.

Sales, marketing, and customer support. Sales, marketing, and customer support expenses primarily consist of personnel costs directly associated with our sales, marketing, and customer support departments, including salaries, bonuses, stock-based compensation and benefits, and allocated overhead. We allocate overhead such as information technology infrastructure, rent and occupancy charges based on headcount. Sales and marketing expense also includes costs for promotional marketing activities, advertising costs, attendance at events and trade shows, and allocated overhead. Sales commissions are expensed as incurred.

General and administrative. General and administrative expenses primarily consist of personnel expenses associated with our executive, finance, legal, human resources and other administrative employees. Our general and administrative expenses also include professional fees for external accounting, legal and other consulting services, and other overhead, as well as third-party costs related to acquisitions.

We incurred certain non-recurring professional fees and other expenses as part of our transition to becoming a public company. Further, we have incurred, and will continue to incur, additional expenses as a result of operating as a public company, including costs to comply with rules and regulations applicable to companies listed on a U.S. securities exchange, costs related to compliance and reporting obligations pursuant to the rules and regulations of the SEC, investor relations and professional services.

Interest expense. Interest expense for the nine months ended September 30, 2021 and 2020 and the years ended December 31, 2020, 2019 and 2018 consists primarily of interest on our outstanding balances under the Prior Credit Facilities and the New Revolving Credit Facility, and also includes debt issuance costs. On October 1, 2020, we entered into the New Revolving Credit Facility and repaid all amounts outstanding under the Prior Credit Facilities. The New Revolving Credit Facility bears interest at LIBOR plus an applicable margin per annum. On April 30, 2021, we used a portion of the net proceeds from the IPO and the concurrent private placement to pay the entire outstanding balance of $22.0 million under the New Revolving Credit Facility. See “Description of Certain Indebtedness.”

44

Other (income) expense. Other (income) expense consists primarily of interest earned on our cash equivalents and short-term investments, gains and losses on foreign currency transactions, and change in fair value associated with contingent considerations related to our acquisitions.

Revenue

Total revenue increased by $61.9 million, or 37%, from $165.3 million in the nine months ended September 30, 2020 to $227.2 million in the nine months ended September 30, 2021.

Advertiser Direct revenue grew $19.8 million, or 27%, in the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020, driven primarily by growth of 65% in Media Transactions Measured for CTV and 91% in Media Transactions Measured for social channels.

Advertiser Programmatic revenue grew $37.7 million, or 50%, in the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020, driven primarily by continued adoption of our premium-priced Authentic Brand Suitability solution. We made a concession of $4.6 million to a Demand-Side Platform partner, which reduced Advertiser Programmatic revenue

45

for amounts that were incorrectly billed by the partner and remitted to us in the period from January 2018 through December 2019. This concession was recorded in the third quarter of 2020.

Supply-Side revenue grew $4.5 million, or 28%, in the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020, primarily driven by increased uptake of our solutions from our platform and publisher customers.

Cost of Revenue (exclusive of depreciation and amortization shown below)

Cost of revenue increased by $12.0 million, or 50%, from $24.0 million in the nine months ended September 30, 2020 to $35.9 million in the nine months ended September 30, 2021. The increase was primarily due to higher partner costs from revenue-sharing arrangements with our Advertiser Programmatic partners, as well as higher software and other technology costs to support our increased volumes.

Product Development Expenses

Product development expenses increased by $11.3 million, or 33%, from $34.3 million in the nine months ended September 30, 2020 to $45.7 million in the nine months ended September 30, 2021. The increase was primarily due to an increase in personnel costs of $8.6 million, which reflects our continued hiring of resources to support our product-development efforts, in addition to $1.5 million of stock-based compensation expenses, $0.5 million of higher office expenses and $0.6 million of higher software expenses.

Sales, Marketing and Customer Support Expenses

Sales, marketing and customer support expenses increased by $12.8 million, or 30%, from $41.9 million in the nine months ended September 30, 2020 to $54.7 million in the nine months ended September 30, 2021. The increase was primarily due to an increase in personnel costs, including sales commissions, of $11.2 million to support our sales efforts, grow market presence in international markets, drive continued expansion with our existing customers, and support existing and new customers, in addition to increased stock-based compensation expenses of $2.9 million.

General and Administrative Expenses

General and administrative expenses increased by $29.0 million, or 99%, from $29.3 million in the nine months ended September 30, 2020 to $58.3 million in the nine months ended September 30, 2021. The increase was primarily due to $20.0 million of higher transaction costs associated with the preparation and completion of our IPO, as well as an increase in compensation expenses of $7.6 million and an increase in stock-based compensation expenses of $4.2 million. This was partially offset by a reduction of $2.7 million in other general and administrative expenses, which was comprised primarily of a reversal in bad debt expense of $1.2 million.

Depreciation and Amortization

Depreciation and amortization increased by $3.8 million, or 21%, from $18.2 million in the nine months ended September 30, 2020 to $22.0 million in the nine months ended September 30, 2021. The increase was primarily due to an increase in depreciation related to capital expenditures.

Interest Expense

Interest expense is mainly related to our Prior Credit Facilities and New Revolving Credit Facility, which carry a variable interest rate. Interest expense decreased by $2.0 million, from $3.0 million in the nine months ended September 30, 2020 to $0.9 million in the nine months ended September 30, 2021. The decrease was attributable to a reduction in outstanding debt.

Other Expense, Net

Other income decreased by less than $0.1 million, from a loss of $0.4 million in the nine months ended September 30, 2020 to a loss of $0.4 million in the nine months ended September 30, 2021, primarily due to a decrease in realized gains for changes in fair value related to contingent payments from our acquisition of Zentrick NV in February 2019, partially offset by changes in exchange rates.

46

Income Tax Expense (Benefit)

Income tax expense grew by $6.4 million from $2.0 million in the nine months ended September 30, 2020 to $8.4 million in the nine months ended September 30, 2021. The increase was primarily due to an increase in pre-tax income, after taking into account permanent book to tax income adjustments. The most material of these adjustments during these periods relate to Research and Development tax credits and the adding back of non-deductible transaction costs for tax purposes.

Revenue

Total revenue increased by $61.3 million, or 34%, from $182.7 million in the year ended December 31, 2019 to $243.9 million in the year ended December 31, 2020. Our advertiser net revenue retention rate was 123% for the year ended December 31, 2020, and 156% for the year ended December 31, 2019, which included the benefit of new sales of Authentic Brand Safety launched at the end of 2018.

Advertiser Direct revenue grew $22.0 million, or 26%, primarily due to $12.5 million of growth in revenue from existing services and $9.5 million of growth in revenue from increased adoption of services on social media platforms. Of the $12.5 million in growth

47

from existing services, $14.9 million was driven by an increase in volume of Media Transactions Measured, partially offset by a $2.4 million decrease in average Measured Transaction Fees primarily driven by expansion across international markets.

Advertiser Programmatic revenue grew $32.6 million, or 39%, primarily due to $37.3 million of growth in revenue from existing services partially offset by a $4.6 million vendor concession. Of the $37.3 million of growth from existing services, $17.1 million was due to an increase in volume of Media Transactions Measured, and $20.2 million was due to an increase in average Measured Transaction Fees primarily driven by the adoption of the Authentic Brand Safety solution which was launched at the end of 2018.

Supply-Side revenue grew $6.6 million, or 45%, primarily driven by $4.6 million of revenue from acquired businesses.

Cost of Revenue (exclusive of depreciation and amortization shown below)

Cost of revenue increased by $11.0 million, or 44%, from $24.8 million in the year ended December 31, 2019 to $35.8 million in the year ended December 31, 2020. The increase was primarily due to growth in Advertiser Programmatic revenue which drove increases in partner costs from revenue-sharing arrangements, as well as higher software and other technology costs to support our increased volumes.

Product Development Expenses

Product development expenses increased by $15.4 million, or 49%, from $31.6 million in the year ended December 31, 2019 to $47.0 million in the year ended December 31, 2020. The increase was primarily due to an increase in personnel costs of $11.0 million, which reflects our continued hiring of resources to support our product-development efforts.

Sales, Marketing and Customer Support Expenses

Sales, marketing and customer support expenses increased by $23.8 million, or 62%, from $38.4 million in the year ended December 31, 2019 to $62.2 million in the year ended December 31, 2020. The increase was primarily due to an increase in personnel costs of $17.3 million to support our sales efforts, build market presence in international markets, drive continued expansion with our existing customers, as well as support both existing and new customers. The increase in non-personnel expenses was mainly related to an increase in sales commission expenses due to growth in revenue.

General and Administrative Expenses

General and administrative expenses increased by $26.2 million, or 97%, from $26.9 million in the year ended December 31, 2019 to $53.1 million in the year ended December 31, 2020. The increase was primarily due to a $12.8 million increase in stock-based compensation expense, a $3.7 million increase in other personnel costs, a $5.0 million increase in professional services costs, a $2.2 million increase in costs related to the preparation for this offering and operating as a public company, $1.5 million of costs related to the departure of our former Chief Executive Officer and to third-party costs incurred in response to investigating and remediating certain IT/cybersecurity matters that occurred in March 2020.

Depreciation and Amortization

Depreciation and amortization increased by $2.8 million, or 13%, from $21.8 million in the year ended December 31, 2019 to $24.6 million in the year ended December 31, 2020. The increase was primarily due to an increase in amortization related to intangible assets from acquisitions and an increase in depreciation related to capital expenditures.

Interest Expense

Interest expense is mainly related to our Prior Credit Facilities and New Revolving Credit Facility, which carry a variable interest rate. Interest expense decreased by $0.3 million, from $5.2 million in the year ended December 31, 2019 to $4.9 million in the year ended December 31, 2020. The decrease was attributable to a reduction in outstanding debt and a reduction in variable LIBOR rates, partially offset by an increase in debt issuance costs related to the New Revolving Credit Facility. In October 2020, we entered into a New Revolving Credit Facility and repaid all amounts outstanding under the Prior Credit Facilities. For additional information on the New Revolving Credit Facility, see “Description of Other Indebtedness.”

48

Other (Income) Expense, Net

Other income decreased by $0.6 million, from income of $1.5 million in the year ended December 31, 2019 to income of $0.9 million in the year ended December 31, 2020, primarily due to an increase in unrealized losses related to changes in exchange rates.

Income Tax Expense (Benefit)

Our year ended December 31, 2020 resulted in an income tax benefit primarily due to adjustments for research and development tax credits, return to provision adjustments, and other various book to tax items, including stock-based compensation expense.

49

Advertiser Direct revenue grew $24.3 million, or 40%, primarily due to $10.1 million of growth in revenue from existing services and $14.2 million of growth in revenue from increased adoption of services on social media platforms.

Cost of revenue increased by $6.3 million, or 34%, from $18.5 million in the year ended December 31, 2018 to $24.8 million in the year ended December 31, 2019. The increase was primarily due to growth in Advertiser Programmatic revenue which drove increases in partner costs from revenue-sharing arrangements, as well as higher software and other technology costs to support our increased volumes.

Product Development Expenses

Product development efforts increased by $7.4 million, or 30%, from $24.2 million in the year ended December 31, 2018 to $31.6 million in the year ended December 31, 2019. The increase was primarily due to an increase in personnel costs of $6.8 million, which reflects our continued hiring of resources to support our product-development efforts.

Sales, Marketing and Customer Support Expenses

Sales, marketing and customer support expenses increased by $15.2 million, or 65%, from $23.2 million in the year ended December 31, 2018 to $38.4 million in the year ended December 31, 2019. The increase was primarily due to an increase in personnel costs of $10.3 million to support our sales efforts, build market presence in international markets, drive continued expansion with our existing customers, as well as support both existing and new customers. The increase in non-personnel expenses was mainly related to an increase in marketing and promotional activities, including our participation in industry tradeshows and related public relations activities.

General and Administrative Expenses

General and administrative expenses increased by $12.3 million, or 84%, from $14.6 million in the year ended December 31, 2018 to $26.9 million in the year ended December 31, 2019. The increase was primarily due to $2.8 million of costs related to the preparation for this offering and operating as a public company, an increase in personnel costs of $2.3 million, an increase in facilities related costs of $1.4 million, an increase in professional services costs of $1.5 million and an increase in costs related to acquisition expenses of $1.3 million.

Depreciation and Amortization

Depreciation and amortization increased by $3.2 million, or 17%, from $18.6 million in the year ended December 31, 2018 to $21.8 million in the year ended December 31, 2019.

Interest expense increased by $2.1 million, from $3.1 million in the year ended December 31, 2018 to $5.2 million in the year ended December 31, 2019. The increase in interest expense was attributable to increased borrowings under our Prior Term Loan Facilities. In February 2019 we drew down $20.0 million from our Prior DDTL Facility (as defined herein) in connection with the acquisition of Zentrick.

50

Other (Income) Expense, Net

Other income increased by $1.5 million, from less than $0.1 million in the year ended December 31, 2018 to $1.5 million in the year ended December 31, 2019, primarily due to a $1.1 million change in fair value of the contingent payments related to the Zentrick acquisition.

Income Tax Expense (Benefit)

Our effective tax rate of 34.1% for the year ended December 31, 2019 was higher than the U.S. federal statutory income tax rate of 21% primarily due to the impact of state and local income taxes, certain tax credits and the impact of other book to tax differences. Our effective tax rate of (60.4)% for the year ended December 31, 2018, was lower than the U.S. federal statutory income tax rate primarily due to a tax benefit of return to provision adjustments related to deductible transaction costs, changes in statutory rates and the impact of other book to tax differences.

Over the periods presented above, we have experienced significant revenue growth, subject to seasonal fluctuations, and have generated Net Income in every quarter except the three months ended June 30, 2021, which was impacted by significant costs related to our IPO which closed on April 23, 2021. Revenue for the three months ended September 30, 2021 was approximately 136% higher than revenue for the three months ended March 31, 2019, reflecting the rapid growth of the business over that period.

While cost of revenue (exclusive of depreciation and amortization) may fluctuate based on the changing mix of our revenue, we generally expect that over the long term, cost of revenue (exclusive of depreciation and amortization) as a percentage of revenue will decline due to the leverage inherent in our business model.

The absolute increase in general and administrative expense, and the resulting increase in general and administrative expense as percentage of revenue is primarily the result of costs related to our IPO and preparing to be a public company.

53

Adjusted EBITDA as a percentage of revenue has been at or above 24% for each three-month period presented above, including throughout the COVID-19 pandemic, reflecting the strength and resilience of our business.

The quarters ending December 31, 2020 and September 30, 2020 resulted in an income tax benefit primarily due to adjustments for research and development tax credits, return to provision adjustments, and other various book to tax items, including stock-based compensation expense.

Liquidity and Capital Resources

Our operations are financed primarily through cash generated from operations. We have also incurred debt in connection with the Providence Acquisition and to finance subsequent acquisitions. As of September 30, 2021, we had cash of $319.8 million and net working capital, consisting of current assets (excluding cash) less current liabilities, of $67.2 million. As of December 31, 2020, we had cash of $33.4 million and net working capital, consisting of current assets less current liabilities, of $107.9 million. As of December 31, 2019, we had cash of $10.9 million and net working capital, consisting of current assets less current liabilities, of $53.2 million.

We received aggregate net proceeds of $253.2 million from the IPO, after deducting underwriting discount fees of $16.2 million. We also received aggregate net proceeds of $28.9 million from the concurrent private placement, after deducting fees of $1.0 million. We believe our existing cash and cash generated from operations, together with the proceeds from our IPO and concurrent private placement and the undrawn balance under the New Revolving Credit Facility, will be sufficient to meet our working capital and capital expenditure requirements for at least the next 12 months.

We anticipate that our capital expenditures, including capitalized software, will be approximately $10 million to $15 million for 2021. We anticipate our operating lease payment obligations, including capitalized leases, will be approximately $8 million for 2021. Our total future capital requirements and the adequacy of available funds will depend on many factors, including those discussed above as well as the risks and uncertainties set forth under “Risk Factors.”

Our liquidity has not been materially impacted by the COVID-19 pandemic. For additional information on the impact of COVID-19 on our business and financial results, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Factors Affecting Our Performance — COVID-19” and “Risk Factors — Risks Relating to Our Business — Economic downturns and unstable market conditions, including as a result of the COVID-19 pandemic, could adversely affect our business, financial condition and results of operations.”

Debt Obligations

In September 2017, DoubleVerify Inc., as borrower, and DoubleVerify MidCo, Inc., as guarantor, entered into senior secured credit facilities consisting of a $30.0 million term facility and a $7.0 million revolving credit facility (with a letter of credit facility of up to $3.0 million as a sublimit).

In July 2018, such credit facilities were amended and replaced by the Prior Credit Facilities. The Prior Term Loan Facility was payable in quarterly installments of $137,500 with the outstanding balance due in full at maturity in July 2023. In February 2019, DoubleVerify Inc. borrowed $20.0 million under the Prior DDTL Facility, which was payable in quarterly installments of $50,000 with the outstanding balance due in full at maturity in July 2023.

In October 2020, DoubleVerify Inc., as borrower, and DoubleVerify MidCo, Inc., as guarantor, entered into the New Revolving Credit Facility and, in connection therewith, repaid all amounts outstanding under the Prior Credit Facilities.

On December 24, 2020, DoubleVerify Inc. prepaid $68.0 million of the outstanding principal amount under the New Revolving Credit Facility with a portion of the proceeds from the Private Placement (as defined herein). As of December 31, 2020, $22.0 million was outstanding under the New Revolving Credit Facility.

On April 30, 2021, we used a portion of the net proceeds from the IPO and the concurrent private placement to pay the entire outstanding balance of $22.0 million under the New Revolving Credit Facility.

The New Revolving Credit Facility is secured by substantially all of the assets of the Credit Group (subject to customary exceptions) and contain customary affirmative and restrictive covenants, including with respect to our ability to enter into fundamental

54

transactions, incur additional indebtedness, grant liens, pay dividends or make distributions to our stockholders and engage in transactions with our affiliates.

The New Revolving Credit Facility also requires us to remain in compliance with certain financial ratios.

For more information about the Prior Credit Facilities and the New Revolving Credit Facility, see “Description of Certain Indebtedness.”

Operating Activities

For the nine months ended September 30, 2021, cash provided by operating activities was $58.4 million, attributable to net income of $1.0 million, adjusted for non-cash charges of $51.2 million and $6.2 million provided by changes in operating assets and liabilities. Non-cash charges primarily consisted of $22.0 million in depreciation and amortization, $21.8 million of offering costs, and $12.1 million in stock-based compensation.

For the nine months ended September 30, 2020, cash provided by operating activities was $17.8 million, attributable to net income of $12.3 million, adjusted for non-cash charges of $22.7 million and net cash outflows of $17.2 million provided by changes in operating assets and liabilities. Non-cash charges primarily consisted of $18.2 million in depreciation and amortization, $3.0 million in bad debt expense, and $3.6 million in stock-based compensation. The main drivers of the changes in operating assets and liabilities were a decrease in trade payables, accrued expenses, and other liabilities of $2.1 million and an increase of $15.1 million in trade receivables and prepaid assets.

For the year ended December 31, 2020, cash provided by operating activities was $21.2 million, attributable to net income of $20.5 million, adjusted for non-cash charges of $34.2 million and net cash outflows of $33.4 million provided by changes in operating assets and liabilities. Non-cash charges primarily consisted of $24.6 million in depreciation and amortization, $4.8 million in bad debt expense and $6.0 million in non-cash stock-based compensation, partially offset by a $5.1 million credit for deferred taxes. The main drivers of the changes in operating assets and liabilities were an increase in trade receivables and prepaid assets of $39.2 million due to an increase in sales and the timing of cash receipts, and a decrease of $6.0 million in trade payable and accrued expenses and other liabilities.

For the year ended December 31, 2019, cash provided by operating activities was $29.4 million, attributable to net income of $23.3 million, adjusted for non-cash charges of $28.3 million and net cash outflows of $22.2 million provided by changes in operating assets and liabilities. Non-cash charges primarily consisted of $21.8 million in depreciation and amortization, $3.3 million in bad debt expense, $2.0 million in deferred taxes and $1.7 million in non-cash stock-based compensation. The main drivers of the changes in operating assets and liabilities were an increase in trade receivables and prepaid assets of $34.4 million due to an increase in sales and the timing of cash receipts, partially offset by a $12.6 million increase in trade payable and accrued expenses and other liabilities resulting primarily from increased costs to support our revenue growth.

For the year ended December 31, 2018, cash provided by operating activities was $12.1 million, attributable to net income of $3.2 million, adjusted for non-cash charges of $20.0 million and net cash outflows of $11.1 million provided by changes in operating assets and liabilities. Non-cash charges primarily consisted of $18.6 million in depreciation and amortization and $1.4 million in non-cash

55

stock-based compensation, offset by a deferred tax benefit of $2.0 million. The main driver of the changes in operating assets and liabilities was an increase in trade receivables of $13.0 million due to an increase in sales and the timing of cash receipts.

Our cash flows from operating activities are primarily influenced by growth in our operations and by changes in our working capital. In particular, accounts receivable increases in conjunction with our rapid growth in sales and decreases based on timing of cash receipts from our customers. The timing of payments on our liabilities also impacts our cash flows from operating activities. We typically pay suppliers in advance of collections from our clients. Our collection and payment cycles can vary from period to period.

We compute our average days sales outstanding, or DSO, as of a given date based on our trade receivables balance at the end of the period, divided by the average daily revenue of the trailing three-month period. We compute our average days payable outstanding, or DPO, as of a given date based on our trade payables balance at the end of the period, divided by the average daily cost of operating expenses over such period, excluding depreciation, amortization, and certain other costs that are excluded from Adjusted EBITDA. The following table summarizes the DSO and DPO for the periods presented.

	As of			As of
	December 31,			September 30,

For the nine months ended September 30, 2020, cash used for financing activities of $4.9 million was primarily due to $1.2 million of offering costs, $2.0 million of acquisition related deferred payments, and $1.2 million of capital lease payments.

For the year ended December 31, 2020, cash provided by financing activities was $10.4 million, primarily attributable to proceeds of $89.7 million from borrowing on the New Revolving Credit Facility, gross proceeds of $89.3 million from the Private Placement, partially offset by a $142.1 million repayment of debt on the Prior Credit Facilities and on the New Revolving Credit Facility, a $15.5 million repurchase of vested options from our former Chief Executive Officer, $2.7 million of deferred payments related to acquisitions, $1.4 million of capital lease payments, and $3.6 million of costs related to the preparation for the IPO. On November 18, 2020, in connection with a private placement (the "Private Placement") pursuant to the Series A Preferred Stock Purchase Agreement, dated October 27, 2020, by and among the Company, the Providence Investor and the parties thereto, we had $346.2 million of cash inflows related to the purchase of 61,006,432 shares of Series A Preferred Stock by an investor group led by the Tiger Investor (collectively, the "Private Placement Investors"), of which 45,438,756 shares were sold by certain existing stockholders for $260.7 million, which was collected on behalf of and remitted to those stockholders. We retained $85.5 million, net of issuance costs, from the 15,567,676 shares of Series A Preferred Stock sold by the Company. We recognized non-cash charges of $260.7 million resulting

56

from the exchange by certain of our existing stockholders of shares of common stock for an equal amount (prior to giving effect to the reverse stock split) of shares of Series A Preferred Stock.

For the year ended December 31, 2019, cash provided by financing activities was $15.0 million, primarily attributable to proceeds of $20.0 million from borrowings on the Prior DDTL Facility, partially offset by $2.9 million of deferred payments related to acquisitions, and $1.5 million of capital lease payments.

Off-Balance Sheet Arrangements

During the periods presented, we did not have any off-balance sheet arrangements as defined in the rules and regulations of the SEC.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions for the reported amounts of assets and liabilities and related disclosures at the dates of the financial statements, and revenue and expenses during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. We evaluate these estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions, and any such differences may be material.

While our significant accounting policies are more fully described in the Note 2 to our audited consolidated financial statements appearing elsewhere in this prospectus, we believe the following discussion addresses our most critical accounting policies, which are those that are most important to our financial condition and results of operations and require our most difficult, subjective and complex judgments.

Revenue Recognition

We recognize revenue in accordance with ASC 606, Revenue from Contracts with Customers, which we adopted on January 1, 2019, using the modified retrospective method. The adoption of ASC 606 did not result in a material change in the timing or amount of revenue recognized.

Prior to January 1, 2019, the Company recognized its revenue in accordance with ASC 605, Revenue Recognition, when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectability is probable.

In accordance with ASC 606, the Company recognizes revenue under the core principle to depict the transfer of control to its customers in an amount reflecting the consideration to which it expected to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

For Advertiser Direct revenue, our contracts with our customers typically consist of the various ad measurement services that we offer. This service includes access to our software platform that allows customers to access and manage their data related to our services. We deliver our services together when media transactions are measured and charge a contractually fixed Measured Transaction Fee per 1,000 impressions on the number of Media Transactions Measured. We recognize revenue over time when we satisfy a performance obligation by transferring promised services to a customer.

For Advertiser Programmatic revenue, our customers can purchase our services through demand-side platforms that manage ad campaign auctions and inventories on their behalf. Our customers can elect to use our services for evaluating the quality of advertising they are considering purchasing on the demand-side platform. We enter into product integration agreements with our demand-side platform partners. In these arrangements, the customer pays a Measured Transaction Fee to the Company (collected by the demand-

57

side platform) for the successful execution of the purchase of advertising inventory on an exchange. We recognize revenue over time when we satisfy a performance obligation by transferring promised services to a customer.

For transactions that involve third parties, the Company evaluates which party in the arrangement obtains control of the Company’s services (and is therefore the Company’s customer), which impacts whether the Company reports as revenue the gross amounts paid by the advertiser through the demand-side platform or the net amount paid by the Company’s demand-side platform partners. For certain arrangements, customers may purchase the Company’s service offering through a demand-side platform that manages various ad campaign auctions and inventory on behalf of the advertisers. Customers elect to use the Company’s service of evaluating the quality of advertising inventory up for bid on an advertising exchange. The ability to provide these services to customers requires that the Company enter into product integration agreements with demand-side platforms who in turn make the Company’s services available to advertisers. In these arrangements, the customer pays a Measured Transaction Fee to the Company (collected by the demand-side platform) for the successful execution of the purchase of advertising inventory on an exchange. In these transactions, the Company transfers control of the Company’s services directly to the advertiser (who is the Company’s customer) and therefore revenue is recognized for the gross amount paid by the advertiser for the Company’s services. Specifically, the Company transfers control of the data that is influencing the purchasing decisions directly to the customer and the Company is primarily responsible for providing these services to the customer. That is, control of these services (or a right to these services) does not transfer to the demand-side platform before they are transferred to the Company’s customers. Further, the Company has latitude in establishing the sales price with those customers as there is a fixed retail rate card that is included in the product integration agreements with the demand-side platforms or are governed by contracts in place with the customers. Accordingly, the Company records revenue for the gross amounts of the Measured Transaction Fees paid by advertisers for these services and records the amounts retained by the demand-side platforms as a cost of sales.

For supply-side revenue, we offer to our supply-side platform partners arrangements to measure all ads on their platform. These arrangements are typically subscription-based with minimum guarantees, and are recognized on a straight-line basis over the term of the contract, usually twelve months, with any overage recognized as revenue once minimum guarantees are achieved.

Goodwill and Intangibles

Goodwill represents the excess of purchase price over the fair value of tangible net assets and identifiable intangible assets of the businesses acquired. Goodwill and intangible assets deemed to have indefinite lives are not amortized. Intangible assets determined to have finite lives are amortized over their useful lives. Goodwill and intangible assets with indefinite lives are subject to impairment testing annually as of October 1, or whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable, using the guidance and criteria described in the accounting standard for Goodwill and Other Intangible Assets. This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value.

The Company has a single reporting unit. There are many assumptions and estimates used that directly impact the results of impairment testing, including an estimate of future expected revenues, EBITDA, EBITDA margins and cash flows, useful lives and discount rates, and an estimate of value using multiples derived from the stock prices of publicly traded guideline companies applied to such expected cash flows and market approaches in order to estimate fair value. The determination of whether or not goodwill or indefinite- lived acquired intangible assets have become impaired involves a significant level of judgment in the assumptions and estimates underlying the approach used to determine the value of our reporting unit. Changes in our strategy or market conditions could significantly impact these judgments and require an impairment to be recorded to intangible assets and goodwill. There have been no goodwill impairment indicators subsequent to the impairment test performed as of October 1, 2020. For the nine months ended September 30, 2021 and the years ended December 31, 2020 and 2019, there were no impairment indicators related to our intangible assets.

We allocate the fair value of the purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values. The excess of the fair value of the purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. The estimates used in valuing the intangible assets are determined with the assistance of third-party specialists, a discounted cash flow analysis and estimates made by management. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, which is not to exceed one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings.

Stock-Based Compensation

Our stock-based compensation awards relate to restricted stock units and stock options. For purposes of calculating stock-based compensation, we estimate the fair value of the restricted stock units using the grant date stock price or a Monte Carlo Simulation model in instances where a market condition exists. We estimate the fair value of stock options issued using a Black-Scholes option-pricing model. For share- based awards that vest subject to the satisfaction of a service requirement, the fair value measurement date for stock-based compensation awards is the date of grant and the expense is recognized using the accelerated attribution method over the vesting period net of an estimated forfeiture rate. For share-based awards that vest subject to the satisfaction of a market condition, the fair value measurement date for stock-based compensation is the date of grant and the expense is recognized on a straight-line basis over the derived service period or upon achievement of the market condition.

The determination of the fair value of restricted stock units utilizing the Monte Carlo Simulation model is affected by a number of assumptions including expected volatility, risk free rate and the fair market value of the Company’s common stock.

The determination of the fair value of stock option awards utilizing the Black-Scholes model is affected by a number of assumptions, including expected volatility, expected life, risk-free interest rate, expected dividends, and the fair market value of the Company’s common stock. Each of these inputs is subjective and generally requires significant judgment and estimation by management.

● Expected Term: we have opted to use the “simplified method” for estimating the expected term of employee options, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the option, generally 10 years.

● Expected Volatility: we have based our estimate of expected volatility on the historical stock volatility of a group of similar companies that are publicly traded over a period equivalent to the expected term of the stock-based awards.

● Risk-Free Interest Rate: the risk-free rate assumption is based on the U.S. Treasury instruments with maturities similar to the expected term of our stock options.

● Expected Dividend: the expected dividend yield is zero as we have not paid nor do we anticipate paying any dividends on our common stock in the foreseeable future.

Prior to our common stock becoming publicly traded, we estimated the fair value of our common stock as discussed in the section “Fair Value of Common Stock” below.

Fair Value of Common Stock

Pre-IPO 2021 Equity-Based Grants and Valuations

From January 1, 2020 to March 31, 2021, we granted a total of 4,735,801 stock options and 1,999,552 restricted stock units to our employees and directors. On January 24, 2020, we granted 111,988 stock options with a $7.95 strike price and the estimated fair value of our common stock on such grant date was determined to be $7.86. On April 27, 2020, we granted 1,264,186 stock options with a $6.45 strike price and 930,239 restricted stock units and the estimated fair value of our common stock on such grant date was determined to be $6.36. On July 28, 2020, we granted 2,657,475 stock options with a $6.93 strike price and 419,914 restricted stock units and the estimated fair value of our common stock on such grant date was determined to be $6.84. On October 29, 2020, we granted 120,323 stock options with a $17.22 strike price and the estimated fair value of our common stock on such grant date was determined to be $16.83. On December 27, 2020, we granted 143,985 stock options with a $17.22 strike price and 159,698 restricted stock units and the estimated fair value of our common stock on such grant date was determined to be $16.83. On January 28, 2021, we granted 72,660 stock options with a $19.02 strike price and 268,091 restricted stock units and the estimated fair value of our common stock on such grant date was determined to be $18.81. On February 17, 2021, we granted 365,184 stock options with a $20.31 strike price and 212,564 restricted stock units and the estimated fair value of our common stock on such grant date was determined to be $20.19. On March 11, 2021, we made a single grant of 9,046 restricted stock units in accordance with our director compensation policy with a grant date share price valuation of $22.11 and the estimated fair value of our common stock on such grant date was determined to be $21.42. For all restricted stock unit grants between January 1, 2020 and March 31, 2021, our board of

59

directors fixed the grant date share price valuation at a value equal to the exercise price per share for stock options as of the date of the grant.

Historical Valuation Approach

Given the absence of a public trading market for our common stock prior to our IPO, our board of directors exercised reasonable judgment and considered a number of objective and subjective factors to determine the best estimate of the fair value of our common stock, including, with input from management, our financial and operating history, equity market conditions affecting comparable public companies, and the lack of marketability of our common stock.

In addition, our board of directors considered valuations of our common stock prepared by an unrelated third-party valuation firm in accordance with the guidance provided by the American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. These valuations considered recent arm’s length market transactions, where applicable, estimates of future expected revenues, EBITDA, EBITDA margins and cash flows, discount rates, and an estimate of value using multiples derived from the stock prices of comparable publicly traded companies applied to such expected cash flows and market approaches in order to estimate fair value. These assumptions were incorporated in a hybrid approach used to evaluate recent arm’s length market transactions and scenarios in which the Company remained privately held or the Company completed an initial public offering. The hybrid approach included using the Option Pricing Method (OPM) and Probability- Weighted Expected Return Method (PWERM) models.

In November 2020, the Private Placement Investors invested in the Company in the Private Placement at a total enterprise value (the “Total Enterprise Value”) based on arm’s length negotiations, which resulted in a per share valuation of $17.22 (adjusted for the reverse stock split). The Total Enterprise Value represented an equity value of our common stock of approximately 14 times historical revenue for the last twelve months (“LTM Revenue”), less a discount for the lack of marketability of our common stock (“Liquidity Discount”). Based on the Total Enterprise Value from the Private Placement and our board of directors’ belief that it is customary and standard practice for high growth companies in the Company’s industry to use a revenue multiplier to value a company, our board of directors determined that the most appropriate representation of the value of the Company was to attribute value based on LTM Revenue multiplied by 14, less a Liquidity Discount. The LTM Revenue utilized in the per share valuation for the Private Placement was the twelve months ended September 30, 2020, which was the most recent month ended prior to the Company entering into a definitive agreement for the Private Placement and the most recent historical financial information provided to the Private Placement Investors.

For grants of stock options and restricted stock units subsequent to closing of the Private Placement (summarized above), our board of directors continued to utilize this formula of (LTM Revenue × 14) x Liquidity Discount. The Liquidity Discount was determined by our board of directors to be 15% for the valuation following the Private Placement, resulting in the following formula: Valuation = (LTM Revenue × 14) x 0.85. At the January 28, 2021 grant date, the formula was updated for LTM Revenue for the twelve months ended December 31, 2020. At the February 17, 2021 grant date, the formula was updated for LTM Revenue for the twelve months ended January 31, 2021 and the Liquidity Discount was decreased from 15% to 10% to account for additional steps we took in furtherance of this offering. At the March 11, 2021 grant date, the formula was updated for LTM Revenue for the twelve months ended February 28, 2021 and the Liquidity Discount was decreased from 10% to 5% to account for additional steps we took in furtherance of this offering. In addition to looking at historical revenue, our board of directors also considered projected 2021 revenue in setting the valuation for grants of stock options and restricted stock units subsequent to closing of the Private Placement, primarily as a guidepost to ensure that the historical LTM revenue formula was reasonable.

Future Valuation Approach

Following the completion of our IPO, our board of directors no longer determines the fair value of our common stock in accordance with the valuation formula described above under “— Historical Valuation Approach.” Instead, our board of directors determines the fair value of our common stock based on the closing price of our common stock as reported on the date of the grant. The closing price (and therefore, the fair value) of our common stock may fluctuate significantly based on a number of factors that are outside of our control. See “Risk Factors — Risks Related to Our Common Stock and This Offering — The market price of our common stock may be volatile and could decline regardless of our operating performance.”

Taxes

We account for income taxes using the asset and liability method, in accordance with ASC 740. Deferred income taxes are provided for temporary differences in recognizing certain income, expense and credit items for financial reporting purposes and tax reporting purposes. Excess tax benefits and tax deficiencies are recognized in the income tax provision in the period in which they occur.

We record a valuation allowance when it is determined that it is more-likely-than-not that some portion or all of its deferred tax assets will not be realized. As of each reporting date, management considers new evidence, both positive and negative, that could impact management’s view with regard to the future realization of deferred tax assets. For certain tax positions, we use a more-likely-than-not threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. We recognize interest and penalties related to income tax matters in income tax expense.

As of December 31, 2018, we completed the accounting for the Tax Cuts and Jobs Act, or the TCJA, and determined, among other effects, the following impacts to the Company: (a) reduction in the corporate federal tax rate from 35% to 21%, and (b) a minimum tax on certain foreign earnings (global intangible low taxed income, or GILTI) which is treated as a period expense.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have elected to use this extended transition period for complying with certain new or revised accounting standards. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

These exemptions will apply until we no longer meet the requirements of being an emerging growth company. We will remain an emerging growth company until the earlier of (a) the last day of the fiscal year (i) following the fifth anniversary of the completion of our IPO, (ii) in which we have total annual gross revenue of at least $1.07 billion or (iii) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (b) the date on which we have issued more than $1.07 billion in non-convertible debt during the prior three-year period.

Recent Accounting Pronouncements

See Note 2 to our audited consolidated financial statements included elsewhere in this prospectus for more information on the adoption of recent accounting pronouncements.

Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate sensitivities. Our cash, cash equivalents and short-term investments as of September 30, 2021, December 31, 2020 and December 31, 2019 consisted of $319.8 million, $33.4 million and $10.9 million, respectively, in bank deposits and money market funds. Such interest-earning instruments carry a degree of interest rate risk. However, we believe that we do not have any material exposure to changes in the fair value of these assets as a result of changes in interest rates due to the short-term nature of our cash, cash equivalents and short-term investments. As of September 30, 2021, December 31, 2020 and December 31, 2019, we had zero, $22.0 million and $74.1 million, respectively, in variable rate debt outstanding. The New Revolving Credit Facility entered into on October 1, 2020 matures in October 2025 and accrues interest at LIBOR plus a floating rate per annum. Following our IPO and the concurrent private placement and the use of proceeds therefrom to pay the entire outstanding balance of $22.0 million under the New Revolving Credit Facility, as of September 30, 2021, we have no outstanding variable rate indebtedness and have $150 million of availability under the New Revolving Credit Facility.

61

Foreign Currency Exchange Risk

As we expand internationally, our results of operations and cash flows may become increasingly subject to fluctuations due to changes in foreign currency exchange rates. Our revenue is denominated primarily in U.S. dollars. Our expenses are generally denominated in the currencies in which our operations are located, which is primarily in the United States. Movements in foreign currency exchange rates versus the U.S. dollar did not have a material effect on our revenue for 2019. A hypothetical 10% change in exchange rates versus the U.S. dollar would not have resulted in a material change to our 2019 earnings. As our operations in countries outside of the United States grow, our results of operations and cash flows may be subject to fluctuations due to changes in foreign currency exchange rates, which could harm our business in the future. To date, we have not entered into any material foreign currency hedging contracts, although we may do so in the future.

BUSINESS

Our Company

We are a leading software platform for digital media measurement and analytics. Our mission is to increase the effectiveness and transparency of the digital advertising ecosystem. Through our software platform and the metrics it provides, we help preserve the fair value exchange in the digital advertising marketplace.

The advertising industry continues to shift from traditional mediums to an expanding array of digital channels and platforms. Digital advertisers have historically relied on inconsistent, self-reported data from a large number of publishers, social channels and programmatic platforms, making it difficult to form an accurate, unbiased view of how and where their ad budgets are spent. As objectionable content and ad fraud have proliferated across the Internet and other digital channels, advertisers are utilizing independent, third-party solutions to protect their brand equity and optimize the performance of their digital media investments.

Our technology addresses this need by providing unbiased data analytics that enable advertisers to increase the effectiveness, quality and return on their digital advertising investments. Our proprietary DV Authentic Ad metric is our definitive metric of digital media quality which measures whether a digital ad is displayed in a fraud-free, brand-safe environment and is fully viewable in the intended geography. Our software platform delivers this metric to our customers in real time, allowing them to access critical performance data on their digital ads. Customers then leverage our data analytics to improve the efficiency of their digital advertising investments by avoiding wasted media spend on blocked or fraudulent ads and to optimize their media strategies in real time by verifying their highest performing ads and content.

Our software platform is integrated across the entire digital advertising ecosystem, including programmatic platforms, social media channels and digital publishers. We deliver unique data analytics through our customer interface to provide detailed insights into our customers’ media performance on both direct and programmatic media buying platforms and across all key digital media channels (including social, video, mobile in-app and CTV), formats (including display and video) and devices (including mobile, desktop and connected televisions). Our technology enables programmatic media traders to evaluate approximately 220 billion transactions daily, ensuring that a digital ad meets advertiser-defined quality criteria before it is purchased. We also analyze more than 6.5 billion digital ad transactions displayed daily, measuring whether ads are delivered in a fraud-free, brand-safe environment and are fully viewable in the intended geography. Our software platform and unique position in the advertising ecosystem allows us to develop a significant data asset that accumulates over time as we measure an increasing number of media transactions. We are able to leverage our data asset across our existing solutions as well as expand the data asset to launch new solutions that address the evolving needs of advertisers.

Our blue-chip customer base includes many of the largest global brands. We serve over 1,000 customers that are diversified across all major industry verticals, including consumer packaged goods, financial services, telecommunications, technology, automotive and healthcare. In 2020, we had 45 customers who each represented at least $1 million of annual revenue, up from 41 such customers in 2019 and 25 in 2018, with no customer representing more than 10% of our revenue in either 2019 or 2020. We serve our customers globally through our 24 offices in 15 countries, including the United States, United Kingdom, Israel, Singapore, Australia, Brazil, France, Germany and Japan.

We generate revenue from our advertising customers based on the volume of Media Transactions Measured on our software platform, for which we receive a Measured Transaction Fee, enabling us to grow as our customers increase their digital ad spend and as we integrate into new channels and platforms. We have long-term relationships with many of our customers, with an average relationship of almost six years for our top 75 customers and almost seven years for our top 25 customers, and ongoing contractual agreements with a substantial portion of our customer base. We have maintained exceptional customer retention rates with gross revenue retention rates of over 95%, and 100% retention of our top 75 customers, in each of 2020, 2019 and 2018. We are also able to increase revenue per customer as we introduce new solutions, which has resulted in a compounded annual growth in average revenue for our top 50 customers of 29% from 2017 to 2020. The combination of high customer retention and multiple upsell opportunities has resulted in net revenue retention rates of 123% in 2020, 156% in 2019 and 131% in 2018. We have delivered strong historical revenue growth, with a compounded annual growth rate of 50% from 2017 to 2020.

Our Industry

We believe that our business benefits from many of the most significant trends in digital marketing and advertising, including:

Significant Growth in Digital Ad Spend. The global advertising industry represented $569 billion of ad spend in 2020, according to Magna Global, and continues to shift from traditional forms of media to digital channels and platforms. According to Magna Global, global digital ad spend, excluding search, reached over $170 billion in 2020 and is expected to grow to $225 billion by 2023. We believe the shift towards digital spend will continue as new distribution channels and advertising formats emerge that enable advertisers to more effectively reach their target audiences.

Acceleration of Programmatic Ad Buying. Advertisers are increasingly shifting their digital media buying to programmatic platforms, which automate the digital ad buying process through the use of computer algorithms and deliver targeted advertisements utilizing vast data sets. According to Magna Global, global programmatic ad spend was approximately $51 billion in 2020 and is expected to reach $75 billion in 2023 and grow nearly twice as fast as the rest of the digital advertising market over the next five years. Programmatic ad buyers and trading platforms benefit from consistent access to high quality and accurate data to improve purchasing decisions and optimize the efficacy of their ads. Furthermore, advertisers value having a single, unified data source that they can leverage to help make real-time decisions on programmatic ad placements across all channels and formats.

64

Emergence of CTV and Other New Digital Channels. Over time, the emergence of new digital channels, such as social, has attracted significant advertiser interest and investment. In turn, this has created additional demand for digital measurement solutions. According to Magna Global, global digital ad spend on social channels was approximately $87 billion in 2020 and is expected to reach over $120 billion by 2023. Today, CTV represents a large new frontier for digital advertising as the approximately $150 billion of annual global linear television media spend starts to migrate to digital channels. According to eMarketer, there was expected to be over $8 billion of CTV ad spend in the U.S. in 2020 which is expected to double by 2023, with over 50% of ad inventory projected to be bought through programmatic platforms. CTV presents a significant opportunity for full-suite measurement providers due to the fragmented inventory and ad fraud emerging within this channel. Based on the Company Data Analysis, CTV fraud impressions more than tripled from 2019 to 2020.

Importance of Brand Reputation. With the increasing scale of digital media channels, advertisers are placing a greater emphasis on understanding where their ads are placed and the content with which it is presented. Context of ad placement has become as important to a brand as the content of the ad itself. Determining the context and content of a web page, streaming video or social post is more complex than verifying a keyword or article headline and often varies minute-by-minute. This challenge is further complicated by a significant increase in user-generated content, as ad spend on social platforms continues to expand. According to a recent study that we commissioned with The Harris Poll, nearly two-thirds of consumers expressed that they would stop using a brand or product that advertises next to false, objectionable or inflammatory content. More than ever, advertisers are being held accountable for brand and content alignment. In response, advertisers are adopting scalable, sophisticated brand safety and suitability solutions to ensure effective use of their global digital media spend.

Desire to Improve Media Quality and Effectiveness. The significant growth in digital advertising has resulted in increased fraud and wasted ad spend due to ads that are never seen. Juniper Research estimated that approximately $42 billion of global digital media spend was wasted in 2019 as a result of continually evolving ad fraud activities, including bots, fake clicks and fraudulent web sites. New and sophisticated schemes, particularly across emerging channels such as CTV and mobile in-app, are uncovered each day. We have identified over 5,000 fraudulent CTV apps as of December 31, 2020, and we have seen CTV fraud impressions increase 220% in 2020 as compared to 2019. In addition, even when an ad is verified to be fraud- free, there is no certainty that it is actually viewable. According to Merkle, more than 40% of digital ads placed are deemed to be not viewable. To combat these issues, advertisers, digital publishers and media platforms rely on robust measurement solutions to validate the performance of their marketing campaigns and ensure that they are only paying for verified ads.

Rising Adoption of Independent, Cookie-Less, Cross-Platform Measurement Solutions. The proliferation of digital channels, formats and devices has made it more difficult for advertisers to measure campaign performance across all platforms. This measurement has been further complicated by recent moves by some large device manufacturers and certain closed platforms, which are often referred to as “walled gardens,” to restrict cookie and identifier-based data sharing. As a result, advertisers are increasingly adopting full-suite measurement solutions that are not dependent on cookies or cross-site individual-level data trackers and can be used seamlessly across devices, the open web and the walled gardens. Point solutions that only deliver single metrics, often on a limited amount of media, and which are based on challenged data aggregation methods, continue to lose traction with advertisers. This has created a growing demand for independent, third-party providers that provide accredited and unified data analytics that improve the transparency and effectiveness of digital ad spend across the entire ecosystem without relying on cookies. Based on the Company Data Analysis, the total addressable market for our core solutions was less than 25% penetrated in 2020, and we believe that we have the opportunity to expand our customer base in response to increasing demand for our core measurement solutions.

Our Strengths

We believe the following attributes and capabilities form our core strengths and provide us with competitive advantages:

Best-in-Class Software Platform. Our technology stack enables us to develop proprietary advertising performance metrics on each digital ad transaction. This precision sets us apart from our competitors and allows us to combine and deliver performance measurements across fraud, brand safety, viewability and geography into a single, unique metric (the DV Authentic Ad), as well as the flexibility to disaggregate and analyze the individual measurements for each delivered ad. We believe we are able to provide the most robust data analytics in the industry, analyzing hundreds of data points for each delivered ad and across billions of ads every day, with approximately 3.2 trillion Media Transactions Measured by us in 2020.

Broad Ecosystem Coverage. We provide comprehensive performance measurement metrics across all key digital channels where our customers advertise and deliver them through the major platforms through which they purchase advertising. Our technology is

65

integrated into major platforms that provide direct, programmatic and social advertising, including Google, Facebook and The Trade Desk. As new media formats emerge, the strength of our solutions and the flexibility of our software platform allows us to seamlessly onboard new integration partners and secure new partnerships as selling channels for our solutions. For example, as CTV continues to become an increasingly prominent advertising channel, we have secured partnership agreements with multiple leading CTV platforms, including Amazon and Roku, that have certified our measurement solutions for use on their platforms. We believe that we provide the broadest integration and partnership coverage across the industry.

Powerful Network Effect Fueled by a Robust and Scalable Data Asset. Our software platform and unique position in the advertising ecosystem allows us to develop a significant data asset that accumulates over time as we measure an increasing number of media transactions. This virtuous cycle allows us to deliver better results as we build broader data sets and enables us to enhance and expand the solutions we deliver to customers. We collected and analyzed data points on the approximately 3.2 trillion Media Transactions Measured by us in 2020, up from 2.4 trillion Media Transactions Measured in 2019 and 1.4 trillion in 2018. The knowledge from the billions of detailed data points we gather daily has enabled us to develop an extensive data asset that we leverage across our existing solutions as well as expand the data asset to launch new solutions that address the evolving needs of advertisers. The strength of our solutions attracts new customers which increases the ad transactions we measure and data we collect, further strengthening the value of our network.

Compelling Value Proposition Driving High Customer ROI. We enable our customers to optimize return on their marketing investments for a fraction of the underlying media cost. Our unique data analytics are used by our advertiser customers to target the highest performing ad inventory and receive refunds or credits for digital ads that do not meet certain criteria. In addition, our solutions help our customers preserve one of their most important and invaluable assets — brand reputation — by ensuring ads are not shown near content that is inconsistent with their brand message.

Track Record of Successful Product Innovation. We have a track record of developing new solutions for our customers that provide increased relationship value and drive incremental average revenue per customer, thereby deepening our competitive edge. As of November 1, 2021, we had 133 software and data engineers throughout our five research and development centers focused on product development. We launched our first brand safety solution in 2010 and have continued to develop leading-edge solutions ever since. We have continued our track record of innovation in recent years as demonstrated by the launch of Authentic Brand Safety, which we believe is the industry’s only solution that allows advertisers to programmatically avoid unsuitable content across platforms using the same settings established for post-bid evaluation. In 2019, we launched our first CTV solutions which now detect over 100,000 fraudulent device signatures per day, providing significant savings to our clients by preventing wasted ad spend. In 2020, we developed DV Authentic Attention, which we believe is the first solution in the market to combine dozens of ad exposure and user engagement metrics on individual impressions to provide predictive analytics and improve performance outcomes, and introduced our Custom Contextual solution, which allows advertisers to match their ads to relevant content without depending on cookie-based or cross-site tracking.

Loyal and Growing Customer Base. Our customers represent many of the largest advertisers in the world including Colgate-Palmolive, Ford, Mondelēz and Pfizer. In each of 2020, 2019 and 2018, we maintained over 95% gross revenue retention rates across our customer base and retained 100% of our top 75 customers. With this foundation, we were able to drive net revenue retention of 123% in 2020, 156% in 2019 and 131% in 2018 through increased advertising volume and the successful launch of newly-introduced solutions. This growth in our existing customer base together with strong new customer wins has increased the number of customers contributing over $1 million of revenue to 45 customers in 2020, up from 41 in 2019 and 25 in 2018.

Scaled and Profitable Business Model. We have an attractive operating model, driven by the scalability of our platform, the consistent nature of our revenue, our significant operating leverage and low capital intensity. Our platform allows us to provide large-scale data analytics to customers around the world seamlessly and cost-effectively. We are able to scale our solutions efficiently and with limited incremental cost for new customers and additional solutions. Our cost of sales (excluding depreciation and amortization) represented only 15% of revenues and helped deliver an Adjusted EBITDA margin of 30% in 2020. We have grown our business rapidly while also achieving profitability, demonstrating the strength of our platform and business model. For additional detail on costs of sales excluding depreciation and amortization, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations.”

Well-Aligned with Privacy Restrictions and Platform Evolution. We believe that we are well positioned to benefit from broader government regulations and changing industry privacy standards that increasingly restrict the collection and use of personal data for advertising purposes. Additionally, as device manufacturers walled garden platforms aggressively move to curtail the use of cookie-

66

based data collection across their properties, measurement, targeting and advertising analytics solutions that are not based on these tracking and collection tools will benefit. Our core software platform does not rely on third-party cookies, persistent identifiers or cross- site tracking technology to deliver our measurement and analytics solutions. Additionally, the core contextual data set that we use to provide our measurement and analytics solutions can also provide advertisers with an alternative source of data to deliver targeted advertising. To capitalize on this rapidly evolving environment, and to leverage a system that is not reliant on cookie-based or personalized data collection, we introduced our Custom Contextual solution in late 2020, which allows advertisers to match their ads to relevant content in order to maximize user engagement and drive campaign performance, without depending on cookie-based or cross-site tracking. In February 2021, we released DV Authentic Attention, a performance measurement solution that leverages pseudonymous, privacy-friendly data to analyze advertising engagement, as an alternative to individual reach and frequency performance tools. As privacy restrictions evolve, and tracking identifiers such as cookies become increasingly restricted by walled gardens, we believe there will be increased demand for our contextual targeting and performance solutions.

Proven Management Team. We have a strong management team that has extensive experience leading software and digital marketing companies. We believe that our management team will continue to drive our growth, scale and solutions innovation. Furthermore, our Chief Executive Officer, Mark Zagorski, has significant public company experience, including as Chief Executive Officer of a public company in the digital advertising software industry.

Our Opportunity

There is strong global demand across the advertising ecosystem for independent third-party measurement and authentication of digital ads. Advertisers, programmatic platforms, social media channels and digital publishers are collectively placing increased emphasis on the quality and effectiveness of digital ad spend across all channels, formats and devices. According to Magna Global, there was over $170 billion of global digital ad spend in 2020 where our solutions are directly applicable.

We are a leader in a large, fast-growing and underpenetrated market with significant tailwinds. Based on the Company Data Analysis, we estimate that the total addressable market for our core solutions was approximately $13 billion globally in 2020 and was less than 25% penetrated and is expected to grow to approximately $20 billion by 2025 with less than 50% penetration. We believe our market leadership positions us well to generate significant growth across this large, underserved market. Our growth is primarily driven by the fastest growing segments of digital ad spend, which are currently among the least penetrated with our solutions, including mobile in-app, programmatic, social and CTV.

Our Growth Strategy

We intend to continue penetrating the digital advertising market through the following key growth levers:

Growing with Our Current Customers. We expect to continue to grow with our existing customers as they increase their spend on digital advertising and as we introduce new solutions. We expect the increased demand for third-party digital advertising data analytics to fuel continued adoption of our solutions across key channels, formats, devices and geographies. For example, we expect new solutions like Authentic Brand Safety, DV Authentic Attention and Custom Contextual and the ongoing shift from linear TV to CTV to continue to drive growth from our existing customers.

Expanding Our Customer Base. We intend to continue targeting new advertiser, programmatic platform and digital publisher customers who have not yet adopted digital ad measurement solutions, as well as those currently utilizing solutions provided by our competitors or point solutions. With the total addressable market for our core solutions less than 25% penetrated today, we believe that there is ample room for us to add new customers going forward.

Expanding Our International Presence. We intend to continue to grow our presence in international markets in order to meet the needs of our existing customers and accelerate new customer acquisition in key geographies outside of North America. We have expanded into eighteen countries since 2018, which has accelerated our revenue growth in those markets.

Introducing New Solutions and Channels. We will continue to lead the industry in innovation by developing premium solutions that increase our value proposition to our existing customers. We have a strong track record of rolling out new solutions that have high adoption rates with our existing customers. We intend to extend our solutions capabilities to cover new and growing digital channels and devices, including CTV, new mobile apps and other emerging areas of digital ad spend.

Pursuing Opportunistic M&A. Our management team has a proven track record of identifying, evaluating, executing and integrating strategic acquisitions. We have completed four acquisitions since December 2018 to expand our technology and solutions offerings and broaden our geographic footprint. We maintain an active pipeline of potential M&A targets and intend to continue evaluating add-on opportunities to bolster our current solutions suite and complement our organic growth initiatives.

What We Do

We are a leading software platform for digital media measurement and analytics. Our leadership in our industry is based on our differentiated technical capabilities resulting from years of innovation, our breadth of industry accredited solutions, and an expansive network of integration partners that enable us to analyze media transactions across the global digital ecosystem. Our solutions empower our customers to address the evolving and intensifying complexities of measuring the performance of digital advertising. We deliver our suite of solutions through a robust and scalable software platform that provides our customers with unified data analytics. Our broad market coverage of the digital advertising ecosystem and our leading software platform enables us to analyze billions of data points globally each day. We collected and analyzed data points on the approximately 3.2 trillion Media Transactions Measured by us in 2020, up from 2.4 trillion Media Transactions Measured in 2019 and 1.4 trillion in 2018. This volume has enabled us to build a self-reinforcing, proprietary data asset which we redeploy in new solutions that further enhance and expand the analytics that we can deliver to our customers and partners.

Our Solutions

The DV Authentic Ad

The DV Authentic Ad is our definitive metric of digital media quality, which evaluates the existence of fraud, brand safety, viewability and geography for each digital ad:

● Fraud: Our solutions are designed to safeguard advertisers against increasingly sophisticated invalid digital traffic, such as bot fraud, site fraud, malware (including adware), and app fraud. We continuously monitor and analyze billions of delivered digital ads on a daily basis for aberrant activity in order to detect new fraud schemes. Each day, we identify over 500,000 active fraudulent device signatures, distributing them to our partners nearly 100 times per day, thereby enhancing the protection we provide our customers.

● Brand Safety: Our customers use the data analytics that our software platform provides to help prevent their ads from appearing next to content that they do not deem appropriate for their brands and target desired contexts. Our brand safety and suitability solutions evaluate the full context of a webpage including the URL and the specific content. Our approach combines rich content ontology and proprietary artificial intelligence tools with human expertise to appropriately categorize content across over 35 languages. We offer brands the ability to dynamically configure over 85 avoidance categories, nearly half of which contain a risk tier aligned with the recently released industry-defined standards, such as disasters, inflammatory news and politics, and hate speech or profanity allowing brand messages to be delivered in a curated and suitable environment. Customers can use our extensive content categories to target desired contexts for their ads, without relying on third-party cookies, persistent identifiers or cross-site tracking technology. We also offer Authentic Brand Safety, which is an enhanced set of contextual targeting solutions that can be deployed across multiple programmatic platforms.

● Viewability: Digital ads are frequently obscured, paused before fully delivered or placed in locations that are out of view from the intended recipient. We help our customers determine if their ads are in-view by the recipient of each advertisement by providing advanced viewability metrics, including average time-in-view, key message exposure and video player size. Our solutions also leverage our historical data to predict the viewability of ads to optimize programmatic buying decisions.

● Geography: Many of our customers run distinct media campaigns that are targeted toward distinct geographic regions. The intended geography of these media campaigns may be specified due to the content or offer of the digital ad, the language in which it is presented or for compliance reasons. Our customers leverage our solutions to ensure that their geographic targeting requirements are met and that there is language alignment between the digital ad and the intended geographic region.

DV Authentic Attention

We developed DV Authentic Attention, a predictive measure of digital ad performance, by leveraging the data we aggregate to deliver our DV Authentic Ad. Developed in 2020 and released in February 2021, DV Authentic Attention is a performance measurement solution that we believe is the industry’s most comprehensive evaluation of creative exposure and user engagement with a digital ad. When employed by our customers, DV Authentic Attention provides comprehensive, real-time prediction data that helps drive media campaign performance in a privacy-friendly manner, as an alternative to individual reach and frequency performance tools. DV Authentic Attention evaluates the real-time delivery of a digital ad by analyzing dozens of data points on the exposure of the digital ad and the consumer’s engagement with the ad and device. DV Authentic Attention evaluates the entire presentation of an ad through metrics that include viewable time, share of screen, video presentation and audibility. Our customers use DV Authentic Attention to predict which ads will impact consumers and drive outcomes, enabling them to make changes to their media strategies in real time.

Custom Contextual

In late 2020, we launched our Custom Contextual solution to enhance our programmatic advertising solutions. Advertisers use our Custom Contextual solution to match their ads to relevant content in order to maximize user engagement and drive campaign performance. Custom Contextual metrics leverage content- derived analytics data and are not reliant on third-party cookies or cross-site tracking technology. Custom Contextual enables advertisers to target audiences based on key points of interest even in web browsers and operating systems that have phased out or ended the use of third-party tracking technology, thus also positioning them to align with existing privacy regulations.

Supply-Side Solutions

We provide our software solutions and data analytics to publishers and other supply-side customers to enable them to maximize revenue from their digital advertising inventory. Supply-side advertising platforms (such as ad networks and exchanges) utilize our data analytics to validate the quality of their ad inventory and provide metrics to their customers to facilitate the targeting and purchasing of digital ads. We also provide the DV Publisher Suite, a unified solution for digital publishers to manage revenue and increase inventory yield by improving video delivery, identifying lost or unfilled sales, and better aggregate data across all inventory sources. The DV Publisher Suite provides the following features to publishers:

● Unified Analytics: Eliminates manual, cumbersome, and repetitive tasks with automatically pulled reports to quickly aggregate and normalize a publisher’s data and improve decision-making, ROI and operational efficiency.

● Campaign Delivery Insights: Tools gather, normalize and analyze campaign delivery to effectively drive yield on digital direct-sold inventory.

● Media Quality Insights & Optimization: Powering publishers with analytics and data targeting on deliverability, suitability, viewability and existence of fraud to gain insights into performance and automatically implement ad selection targeting to improve yield.

● Industry Benchmarks: Providing insight to publishers on the performance of their inventory in key metrics compared with competing publishers.

● Video Delivery Automation: Improves the user experience and maximizes video revenue from a publisher’s video inventory through automated healing and acceleration technology.

How We Deploy Our Solutions

We provide a consistent, cross-platform measurement standard across all major forms of digital media, making it easier for advertiser and supply-side customers to benchmark performance across all of their digital ads and to optimize their digital strategies in real time. Our coverage spans over 40 key geographies where our customers are located and includes:

● all primary media buying platforms, including direct and programmatic;

● all significant digital media channels, including social, video, mobile in-app and CTV;

69

● all key media formats, including display and video; and

● all major devices, including mobile, desktop and connected televisions.

We also maintain an expansive set of direct integrations across the entire digital advertising ecosystem in order to deliver our metrics to the platforms where our customers buy ads. Our partner integrations include leading programmatic platforms, such as The Trade Desk, Google Display & Video 360, Amazon Advertising and Verizon Media. Through these integrations, our customers utilize our solutions to better evaluate and optimize inventory purchase decisions. We also have direct integrations and partnerships with key social platforms, including Facebook, YouTube, Twitter, Pinterest, TikTok and Snap, as well as leading CTV platforms, including Amazon and Roku, which allow us to deliver more robust social campaign and CTV data analytics to our advertiser customers. Together, we work seamlessly to empower our partners by providing advertisers clarity and confidence in their digital investments across all key platforms.

Our Customer Interface

We believe our proprietary customer interface, DV Pinnacle, is the industry’s first unified service and analytics platform user interface. DV Pinnacle allows our customers to adjust and deploy controls for their media plan and track campaign performance metrics across channels, formats and devices.

Profile and Controls: DV Pinnacle allows brands to set profiles and adjust controls for their media plan’s verification settings which are then consistently and automatically deployed across all of an advertiser’s digital buying channels. Our customers use DV Pinnacle to configure their Authentic Brand Safety settings such as inclusion/exclusion lists, override lists, custom keyword avoidance, inappropriate content avoidance categories, as well as app brand safety controls such as filtering by app category, star reviews and age ratings. These settings are then automatically uploaded into our customers’ programmatic platforms for complete synchronicity between their pre bid and post purchase and measurement settings.

Analytics: DV Pinnacle also provides over 200 analytics and reporting metrics and over 50 industry benchmark filters in an easy-to-use dashboard, in order to track campaign performance metrics across channels, formats and devices. This enables advertisers to gain a clear understanding of the quality and effectiveness of their digital media campaigns and allows them to take appropriate actions for campaign optimization. DV Pinnacle generates industry benchmarks that are dynamically refreshed enabling customers to compare the quality of their ads against their peers and allows users to set specific thresholds on key performance indicators that drive success of the media campaign, such as blocking rates, ad delivery and viewability.

Integration and Channel Partnerships

Our technology is integrated with leading digital advertising technology channels, supporting the distribution of our programmatic solutions and enabling us to analyze a broad footprint of data and deliver a comprehensive analysis for our customers. These digital ecosystem integrations are highly complex, requiring significant time and capital to develop, and they are a key driver of our success by creating highly scalable network effects. Our position as a strong, independent analytics partner has enabled us to integrate with key global platforms, including social channels, many of whom are very selective in granting third parties access to their technology environments.

As new media formats emerge, the strength of our solutions and the flexibility of our software platform allows us to seamlessly onboard new integration partners and secure new partnerships as selling channels for our solutions. For example, as CTV continues to become an increasingly prominent advertising channel, we have secured partnership agreements with multiple leading CTV platforms, including Amazon and Roku, which have certified our measurement solutions for use on their platforms. We believe that we provide the broadest integration and partnership coverage across the industry. Further, as we build new product sets, these flexible integrations and partnerships allow for seamless distribution of new services on existing partner platforms. We maintain a team of dedicated business development professionals who manage existing partnerships and develop new channels.

Select integration and channel partners include:

● Demand-Side Platforms: Amazon, Google, The Trade Desk, Verizon Media Group, AppNexus, MediaMath, Adobe

● Ad Platforms and Exchanges: Yahoo! Japan, SpotX, InMobi, Amobee, Teads, MoPub, Tremor

● Ad Servers and Ratings/Workflow Platforms: Nielsen and MediaOcean Prisma

● Social Platforms: Facebook, Instagram, YouTube, Twitter, Snapchat, Pinterest, TikTok

● CTV: Amazon and Roku

Our advertising customers often purchase the Company’s solutions through a demand-side platform. Demand-side platforms have technology to manage an advertiser’s bidding process on exchanges that facilitate the buying and selling of advertising inventory from multiple advertising networks. Customers leverage the Company’s solutions on demand-side platforms to enable the advertiser to evaluate the quality of advertising inventory up for bid on an advertising exchange. To make the Company’s solutions available to advertiser customers through a demand-side platform, the Company enters into agreements with programmatic partners that allow our technology to be integrated into the demand-side platform and enables customers to access our solutions through the demand-side platform. Pursuant to such agreements, the programmatic partner collects fees from the Company’s advertiser customers and remits them to the Company. Because our advertiser customers, rather than the programmatic partners providing access to the demand-side platform, obtain control of the Company’s solutions to inform their purchasing decision, the Company records revenue for the gross amounts paid by its advertiser customers for these Company-provided solutions, and the amounts retained by the programmatic partners are recorded by the Company as a cost of sales.

The revenue we generated from our customers which was facilitated by our programmatic partnerships was $113.7 million for the nine months ended September 30, 2021, $116.1 million for the year ended December 31, 2020, $83.5 million for the year ended December 31, 2019 and $36.9 million for the year ended December 31, 2018. For additional detail on revenue recognition with respect to our programmatic partnerships, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates — Revenue Recognition.”

Our go-to-market strategy for new customers is focused on driving awareness for our solutions, and fostering relationships with senior brand executives and Chief Marketing Officers of leading brands, agencies and publishers. Our sales presentation is focused on the market challenges that we address, the benefits that customers have achieved utilizing our solutions and the product innovation and differentiation that drive our superior results. We target the largest global advertisers and we believe that we offer the most comprehensive suite of solutions available in the market.

71

Our sales executives are dedicated to one of three functions:

● Strategic Client Development: Senior sales representatives responsible for establishing early connections and maintaining relationships with large, blue-chip brands and global advertising agencies through dedicated engagement focused on how to help them achieve their broader corporate initiatives

● Direct: Sales representatives dedicated to working with brands and their advertising agencies that are interested in using DV Authentic Ad to analyze the quality and effectiveness of their digital advertising investment across all key channels, formats and devices after an ad is purchased

● Programmatic: Sales representatives focused on the media traders at brands or agencies who are responsible for ads purchased programmatically and interested in using our platform to optimize digital campaign strategies by predicting the quality and effectiveness of an ad before a bid is made

Our sales organization is organized by geographic regions and consists of three regional teams: Americas, EMEA and APAC. We regularly seek to expand into new geographies based on demand from existing customers and the attractiveness of the potential market opportunity, including recent expansion in Japan and India.

Our marketing team’s objectives are to build brand leadership globally, drive sales empowerment through lead generation and top-of-funnel pipeline growth, and support customer retention and up-sell through industry insights, thought leadership and analysis of customer data. We execute this strategy through frequent publications of industry insight reports, whitepapers, case studies, earned media, participation at industry conferences and frequent engagement with the world’s leading brands.

As of November 1, 2021, we had 157 sales professionals, of which 120 were sales representatives and 37 were marketing professionals. Our sales and marketing expenses were $39.4 million, $42.9 million and $26.5 million for the nine months ended September 30, 2021 and the years ended December 31, 2020 and 2019, respectively.

Customers

As of November 1, 2021, we had more than 1,000 customers, comprising many of the world’s largest global brands, publishers and other supply-side customers, spanning all major industry verticals including consumer packaged goods, financial services, telecommunications, technology, automotive and healthcare. Our customers currently include over 50 of the top 100 global advertisers, according to Ad Age, including Colgate- Palmolive, Ford, Mondelēz and Pfizer. Our solutions drive customer loyalty, with net revenue retention of 123% in 2020 and an average relationship of over six years for our top 50 customers. No customer accounted for more than 10% of our revenue for the year ended December 31, 2019 or 2020.

Customer Support

Our customer support team handles all aspects of customer service from pre-sale technical support to client onboarding, training and implementation of our services. The largest part of the client services department is our dedicated account managers which help customers maximize the value of using our platform. Account managers are responsible for overseeing the technical implementation, client training, ongoing support, proactive optimization recommendations, remediation with media properties and identifying potential incremental opportunities to expand usage of our services. Account managers work closely with product managers to provide direct customer feedback, which is also shared with our technology and development organization, enabling them to implement ongoing improvements and identify potential new product categories. As part of the process of launching new solutions, our account management team works collaboratively with existing customers and their sales representative to highlight the potential benefits to implementing these solutions into their digital ad campaigns. We rely on our account management team to ensure customer satisfaction and retention while also identifying growth opportunities.

As of November 1, 2021, we had 162 members of the client services team, including 117 account managers. Our customer support expenses were $15.2 million, $19.2 million and $11.9 million for the nine months ended September 30, 2021 and the years ended December 31, 2020 and 2019, respectively.

72

Product Development

Ongoing product innovation is central to our business. Rapid advancement of our product capabilities has enabled our business to meet customer needs in the dynamic digital advertising landscape. Through our innovation, we have been able to seamlessly add new capabilities to our solutions over time.

Our engineering team, consisting of 193 employees as of November 1, 2021, is responsible for the development of software and the operations of our infrastructure. As of November 1, 2021, we had 133 software and data engineers globally throughout our five research and development centers focused on product development. We use an agile development process with automated quality assurance, deployment and post-deployment testing to rapidly build, test and deploy new functionality.

Our product team, consisting of 111 employees as of November 1, 2021, is responsible for working with our sales, account management, marketing and business development teams to understand customer input, assess the market opportunity and define the product roadmap. This team is structurally aligned with our engineering organization to ensure there is direct accountability for all aspects of research and product development. Our team includes expert linguists, content classification analysts, fraud researchers and other supporting operational roles which provide the domain expertise and ongoing product development to ensure the highest possible quality of our technology.

Our product development expenses were $45.7 million, $47.0 million and $31.6 million for the nine months ended September 30, 2021 and the years ended December 31, 2020 and 2019, respectively. We intend to continue to invest in our research and development capabilities to extend our platform to cover a broader range of products, customers and geographies.

Technology

Our technology is designed to provide our customers with precise, real-time decision-making and measurement data across their digital advertising campaigns. Our proprietary technology analyzes more than 6.5 billion digital ad transactions each day, measuring whether ads are delivered in a fraud-free, brand- safe environment and are fully viewable in the intended geography. We own or perpetually license all aspects of our software which we have built to be flexibly implemented on a variety of environments, allowing us to minimize cost while delivering the latency, growth and privacy needs of our global customers.

Our commitment to providing innovative and accurate advertising data and analytics is accomplished through the following core technology components:

● Configurable Settings: We have built a flexible configuration profile and settings distribution solution that allows customers to apply our software to their unique needs and brand preferences. Our flexible technology ensures that new campaigns and configurations are distributed across our global infrastructure in minutes.

● Omni-Channel Display and Video Measurement Tags: We have built video and display measurement tags that seamlessly operate in any format or device, enabling simple tagging processes that minimize customer trafficking needs.

● Advanced Owned & Operated Semantic Science Technology: Our owned and operated semantic science technology provides accurate and granular content classifications using machine learning and an ontology of over 200,000 distinct content topics.

● Deterministic, Cross-Channel Fraud and Invalid Traffic Identification: We operate multiple proprietary fraud and invalid traffic detection models that benefit from the scale of the ads we analyze on a daily basis. Our fraud lab includes a dedicated team of data scientists, mathematicians and analysts from the cyber-fraud prevention community and we leverage AI, machine learning and manual review to detect new forms of fraud. Fraud signature updates are distributed into our serving infrastructure and to our partners nearly one hundred times per day to ensure maximum real- time protection for our customers and the deterministic nature of our algorithms helps to systematically assess risk.

● Deeply Embedded Technology: Our technology is deeply embedded into major platforms and partners that provide direct, programmatic and social advertising. These integrations represent years of collective development, joint integration and ongoing quality assurance work between us and our partners.

73

● Unified Analytics: Our customized analytics provide unified insights and analytics to both the digital advertising buyer and seller on every measured ad. We operate customized analytics dashboards, configurable insights and data delivery engines and seamless data integrations that maximize the utility of the data produced by our software.

● Privacy Framework: We have built a privacy framework that is directly integrated into our measurement technology. This framework allows us to modify our services in real-time based on the regulatory jurisdiction and data collection consent status of each individual measured ad. Additionally, our core software platform does not rely on third-party cookies, persistent identifiers or cross-site tracking technology when deploying our solutions, making them more compatible with the expanding global regulatory framework related to data privacy.

● Dedicated Information Security: Our platform hosts a large quantity of our customer media campaign data. We maintain a comprehensive information security program designed to ensure the security and integrity of our systems and our customers’ data. Our security program includes network intrusion monitoring and detection sensors deployed throughout our infrastructure and we have a dedicated staff that monitors our network. In addition, we obtain third party security assessments and audits of our infrastructure and security.

● Reliable, Scalable and Redundant Infrastructure: We operate a global proprietary and redundant infrastructure that is highly available, fault tolerant and capital efficient.

Certifications and Accreditations

Digital advertising measurement is subject to numerous governing industry standards, guidelines and best practices. Supporting these standards are organizations that conduct audit-based accreditations and other certification processes for media measurement products and to renew accreditations on an annual basis. We have received accreditations and certifications from a wide range of industry bodies, including the Media Rating Council (MRC), Trustworthy Accountability Group, Audit Bureau of Circulations, German Association for the Digital Economy (BVDW) and Centre d’Étude des Supports de Publicité (CESP).

The MRC is a U.S. based independent organization that updates and maintains the Minimum Standards for Media Rating Research (the “MRC Minimum Standards”), which set strict guidelines for the media measurement industry and are intended to ensure:

● accurate, reliable, and ethical procedures for producing ratings and audience research;

● transparent and verifiable methodologies and survey information; and

● secure and thorough electronic data reporting systems.

We are accredited by the MRC for our impression measurement solutions, including fraud, brand safety, display viewability and video viewability, and our proprietary metric, the DV Authentic Ad. In late 2020, we were the first third-party solution to gain MRC accreditation for integrated viewability measurement on Facebook. In early 2021, we received MRC accreditation for display and video rendered ad impression measurement and sophisticated invalid traffic (SIVT) filtration, including app fraud, in the CTV media environment and, in July 2021, we received MRC accreditation for video filtering, benchmarks, and CTV fully on-screen metrics. To receive these MRC accreditations, an independent third-party conducts annual audits of our solutions to evaluate whether they meet the MRC Minimum Standards, which include a technical review of our measurement and data analytics services and an evaluation of how we operate within the technical environments of the digital advertising ecosystem.

The accreditations and certifications of our products gives advertisers confidence in the efficacy and reliability of our solutions. These accreditations and certifications also ensure that our partners and other participants in the digital advertising ecosystem that are impacted by our digital media measurement can trust that our solutions are consistent, fair and meet industry standards. We continue to invest in maintaining and growing our accreditations and certifications as they are a key element to ensuring our solutions are trusted by market participants around the globe. The expansive coverage of our certifications and accreditations across metrics, standards, devices and regions represents a significant expenditure of capital and years of auditing that can be difficult for new market entrants to obtain.

74

Competition

We operate in a competitive end market with multiple different types of competitors. Our primary competition is other digital ad measurement providers, including Integral Ad Science and Moat and Grapeshot, which are part of the Oracle Data Cloud. There are several companies that provide point solutions that address individual aspects of digital ad measurement, such as HUMAN (formerly known as White Ops) and Zefr, or geographically focused companies. Some of our ad platform partners also offer their own measurement solutions solely for ads placed through their ad buying tools.

We believe the principal competitive factors in our market include the following:

● the ability to provide a unified and consistent MRC-accredited measurement of digital ads across all formats and channels;

● the ability to provide accurate and reliable data insights on the brand suitability, existence of fraud and viewability of each digital ad to ensure that it meets all of these criteria;

● the ability to innovate and adapt product offerings to emerging digital media technologies and offer products that meet changing customer needs;

● the ability to support large, global customers and develop and maintain complex integrations with key partners across the digital advertising ecosystem;

● the ability to achieve and maintain industry accreditations; and

● the ability to collect this data across all key platforms and provide independent analytics to our customers.

We believe we compete favorably on these factors and we will continue to provide valuable data and analytics to our customers.

Intellectual Property

The protection of our intellectual property is important to our success and our internally developed technology provides the foundation of our proprietary suite of products. We rely on intellectual property laws in the U.S. and abroad, as well as confidentiality procedures and contractual restrictions, to protect our intellectual property. We believe our products are difficult to replicate and we will continue to enhance our intellectual property portfolio as we develop new products and services for our customers.

As of November 1, 2021, we had one registered U.S. patent, four international patents (two in Japan and two in Finland) and ten pending patent applications, including three in the U.S. We also hold various service marks, trademarks and trade names, including DoubleVerify, our logo design, DV Authentic Ad, DV Authentic Attention, DV Pinnacle, Authentic Brand Safety and Authentic Brand Suitability, that we deem important to our business. As of November 1, 2021, we had eight registered U.S. trademarks and seven pending U.S. trademark applications, and nine trademarks that we have registered in various jurisdictions abroad.

Employees

As of November 1, 2021, we had 774 employees in offices in the United States and around the world, including in the United Kingdom, Israel, Singapore, Australia, Brazil, Mexico, France, Germany, Finland, Japan and Belgium. Around two-thirds of our employees are based in New York, London and Tel Aviv. Our team draws from a broad range of experiences, including technology, investments, sales and research and development. As of November 1, 2021, none of our employees were subject to collective bargaining agreements in the United States or similar arrangements internationally. In certain countries in which we operate, we are subject to, and comply with, local labor law requirements which may automatically make our employees subject to industry-wide collective bargaining agreements.

Properties

Our corporate headquarters are located in New York, New York, where we occupy approximately 32,000 square feet under a lease that expires in November 2023. We lease several additional properties and flexible co- working space in North America, Europe, South America, Asia and Australia. We believe that our properties are adequate for our current needs and if we require additional space, we believe that we would be able to obtain such space on commercially reasonable terms.

75

Regulatory Matters

U.S. and international data security and privacy laws apply to our business. As a general matter, our core software platform does not rely on third-party cookies, persistent identifiers or cross-site technology, but our measurement of digital ads depends, in part, on the use of certain tracking technologies to measure a user’s views and interactions with digital ads. Our ability, like those of other advertising technology companies, to use such tracking technologies is governed by U.S. and foreign laws and regulations, which change from time to time. Additionally, many countries have data protection laws with different requirements than those in the U.S. and this may result in inconsistent requirements and differing interpretations across jurisdictions. Governments, privacy advocates and class action attorneys are increasingly scrutinizing data privacy.

New laws restricting the collection, processing and use of personal data have been enacted in California (the CCPA and the CPRA) and other states in the U.S., Brazil (the LGPD) and Europe (GDPR), and more are being considered that may affect our ability to implement our business models effectively. Further, COPPA applies to websites and other online services that are directed to children under thirteen (13) years of age and imposes certain restrictions on the collection, use and disclosure of personal information from these websites and online services. Changes or expansions to these and other legislation or regulations that further restrict the collection, processing and use of personal data could result in changes to the digital advertising ecosystem and our channel partners’ business practices and may require us to alter the functionality of our measurement solutions. We continue to monitor changes in all applicable data security and privacy regulations and laws in order to maintain compliance with such regulations and laws.

Legal Proceedings

We are not currently a party to any legal proceedings that would, either individually or in the aggregate, have a material adverse effect on our business, financial condition or cash flows. We may, from time to time, be involved in legal proceedings arising in the normal course of business. The outcome of legal proceedings is unpredictable and may have an adverse impact on our business or financial condition.

Corporate Governance

Board Composition and Director Independence

Our board of directors is currently composed of nine directors. Our amended and restated certificate of incorporation provides for a classified board of directors, with members of each class serving staggered three-year terms as follows:

● Our Class I directors are Laura B. Desmond, Joshua L. Selip and Rosie Perez, and their terms will expire at the annual meeting of stockholders to be held in 2022.

● Our Class II directors are R. Davis Noell, Lucy Stamell Dobrin and Teri L. List, and their terms will expire at the annual meeting of stockholders to be held in 2023.

● Our Class III directors are Mark Zagorski, Kelli Turner and Scott Wagner, and their terms will expire at the annual meeting of stockholders to be held in 2024.

Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. See “Description of Capital Stock — Anti-Takeover Effects of Our Certificate of Incorporation and Bylaws — Classified Board of Directors.”

In connection with our IPO, we and the Providence Investor entered into the Stockholder’s Agreement pursuant to which, among other matters, Providence has the right to designate nominees for our board of directors, whom we refer to as the “Providence Designees,” subject to the maintenance of specified ownership requirements. See “Certain Relationships and Related Party Transactions — Relationship with Providence — Stockholders Agreements.”

The number of members on our board of directors may be fixed by resolution adopted from time to time by the board of directors. Subject to the Stockholder’s Agreement, any vacancies or newly created directorships may be filled only by the affirmative vote of a majority of directors then in office, even if less than a quorum, or by a sole remaining director. Each director shall hold office until his or her successor has been duly elected and qualified, or until his or her earlier death, resignation or removal.

Our board of directors has determined that Laura B. Desmond, Teri L. List, Kelli Turner, Rosie Perez and Scott Wagner are “independent” as defined under NYSE rules, and that Teri L. List, Kelli Turner and Rosie Perez are “independent” as defined under Rule10A-3 under the Exchange Act applicable to members of our audit committee.

Controlled Company

After the completion of this offering, we anticipate that Providence will continue to control a majority of the voting power of our outstanding common stock. Accordingly, we expect to continue to qualify as a “controlled company” within the meaning of NYSE corporate governance standards. Under NYSE rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain NYSE corporate governance standards, including:

● the requirement that a majority of the board of directors consist of independent directors;

● the requirement that our Nominating and Corporate Governance Committee be composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities;

● the requirement that we have a Compensation Committee that is composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and

● the requirement for an annual performance evaluation of the Nominating and Corporate Governance and Compensation Committees.

80

Following this offering, we intend to continue to utilize many of these exemptions. Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of the NYSE corporate governance rules and requirements. The “controlled company” exception does not modify audit committee independence requirements of Rule 10A-3 under the Exchange Act and NYSE rules.

Board Committees

Our board of directors maintains an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. Under NYSE rules and Rule 10A-3 under the Exchange Act, we are required to have one independent director on our Audit Committee during the 90-day period beginning on the date of effectiveness of the registration statement on Form S-1 filed with the SEC under the Securities Act in connection with our IPO (the “IPO registration statement”). After such 90-day period and until one year from the date of effectiveness of the IPO registration statement, we are required to have a majority of independent directors on our Audit Committee. Thereafter, our Audit Committee is required to be composed entirely of independent directors. As a “controlled company,” we are not required to have independent Compensation or Nominating and Corporate Governance Committees. The following is a brief description of our committees.

Audit Committee

Our Audit Committee is responsible, among its other duties and responsibilities, for overseeing our accounting and financial reporting processes, the audits of our financial statements, the qualifications and independence of our independent registered public accounting firm, the effectiveness of our internal control over financial reporting and the performance of our internal audit function and independent registered public accounting firm. Our Audit Committee is responsible for reviewing and assessing the qualitative aspects of our financial reporting, our processes to manage business and financial risks, and our compliance with significant applicable legal, ethical and regulatory requirements. Our Audit Committee is directly responsible for the appointment, compensation, retention and oversight of our independent registered public accounting firm. The charter of our Audit Committee is available without charge on the investor relations portion of our website.

The members of our Audit Committee are Teri L. List (Chairperson), Lucy Stamell Dobrin, Kelli Turner and Rosie Perez. Our board of directors has designated Teri L. List as an “audit committee financial expert,” and each of the members has been determined to be “financially literate” under NYSE rules. Our board of directors has also determined that Teri L. List, Kelli Turner and Rosie Perez are “independent” as defined under NYSE and Exchange Act rules and regulations.

Compensation Committee

Our Compensation Committee is responsible, among its other duties and responsibilities, for reviewing and approving all forms of compensation to be provided to, and employment agreements with, the executive officers and directors of our company and its subsidiaries (including the Chief Executive Officer), establishing the general compensation policies of our company and its subsidiaries and reviewing, approving and overseeing the administration of the equity compensation plans of our company and its subsidiaries. Our Compensation Committee also periodically reviews management development and succession plans. The charter of our Compensation Committee is available without charge on the investor relations portion of our website.

The members of our Compensation Committee are R. Davis Noell (Chairperson), Laura B. Desmond, Teri L. List and Scott Wagner. Our board of directors has determined that Laura B. Desmond, Teri L. List and Scott Wagner are “independent” as defined under NYSE rules and regulations for purposes of the Compensation Committee. In light of our continued status as a “controlled company” within the meaning of the corporate governance standards of the NYSE following this offering, we are exempt from the requirement that our Compensation Committee be composed entirely of independent directors under listing standards applicable to membership on the Compensation Committee, with a written charter addressing the committee’s purpose and responsibilities and the requirement that there be an annual performance evaluation of the Compensation Committee. We intend to continue to utilize one or more of these exemptions.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee is responsible, among its other duties and responsibilities, for identifying and recommending candidates to the board of directors for election to our board of directors, reviewing the composition of the board of directors and its committees, developing and recommending to the board of directors corporate governance guidelines that are

81

applicable to us, and overseeing board of directors evaluations. The charter of our Nominating and Corporate Governance Committee is available without charge on the investor relations portion of our website.

The members of our Nominating and Corporate Governance Committee are Laura B. Desmond (Chairperson), Teri L. List and R. Davis Noell. In light of our continued status as a “controlled company” within the meaning of the corporate governance standards of the NYSE following this offering, we are exempt from the requirement that our Nominating and Corporate Governance Committee be composed entirely of independent directors, with a written charter addressing the committee’s purpose and responsibilities and the requirement that there be an annual performance evaluation of the Nominating and Corporate Governance Committee. We intend to continue to utilize one or more of these exemptions.

Compensation Committee Interlocks and Insider Participation

During the last completed fiscal year, Wayne T. Gattinella, Laura B. Desmond, Teri L. List and R. Davis Noell served as members of our Compensation Committee. Mr. Gattinella was our Chief Executive Officer and President until February 28, 2020, and Ms. Desmond, Ms. List and Mr. Noell serve on our board of directors.

During the last completed fiscal year, none of our executive officers served as a member of the Compensation Committee (or other committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) or as a director of another entity, one of whose executive officers served on our Compensation Committee or on our board of directors.

For related party transaction disclosure relating to members of our Compensation Committee, see “Certain Relationships and Related Party Transactions — Relationships with Directors and Officers.”

Code of Business Conduct

We have a Code of Business Conduct that applies to all of our directors, officers, employees and financial professionals. The Code of Business Conduct addresses matters concerning ethical conduct, such as actual or apparent conflicts of interest, confidentiality, fair dealing and compliance with laws and regulations. The Code of Business Conduct is available without charge on the investor relations portion of our website.

Mr. Grimmig was also entitled to be granted 882,347 non-qualified stock options under our 2017 Equity Plan, all of which have been granted and which are described in greater detail below in the table and accompanying footnotes under “— Outstanding Equity Awards at Fiscal Year End 2020”.

Mr. Grimmig’s employment agreement includes non-compete and employee and customer non- solicitation covenants, effective during his employment and for one-year post-termination. Mr. Grimmig is also entitled to receive severance benefits upon a qualifying termination of his employment, as more fully described below under “— Payments and Potential Payments upon Termination or Change of Control”.

Mr. Zagorski, Mr. McLaughlin and Mr. Grimmig are also bound by intellectual property assignment and perpetual confidentiality provisions that protect our commercial interests.

Wayne Gattinella

Mr. Gattinella’s employment agreement terminated on February 28, 2020, concurrent with his departure from the Company. Certain terms of the agreement, including Mr. Gattinella’s one-year post- termination non-compete and non-solicitation covenants, survived in accordance with their terms.

Laura Desmond

Ms. Desmond did not have an employment agreement with the Company. Prior to the completion of our IPO, we were party to a letter agreement with Ms. Desmond that outlined her compensation for serving as a member of our board of directors and provided for payment of a cash payment for her services as Interim Chief Executive Officer. This letter agreement terminated upon the completion of our IPO. Ms. Desmond’s compensation is now determined in accordance with our compensation program for non- employee directors.

Annual Cash Incentive Program

For 2020, each of Mr. McLaughlin and Mr. Grimmig was eligible to receive a cash incentive bonus at a percentage of his annual base salary (65% for Mr. McLaughlin and 50% for Mr. Grimmig), based on the achievement of certain financial and operating performance goals that were approved by our Compensation Committee. For Mr. Grimmig, a portion of his target bonus for 2020 was guaranteed pursuant to the terms of his employment agreement. For 2020, the performance goals included revenue, Adjusted EBITDA, and certain operational and strategic objectives, in each case with separate targets for the first half of the year, the second half of the year and the full year. Mr. McLaughlin’s bonus for 2020 and the non-guaranteed portion of Mr. Grimmig’s bonus for 2020 have each been paid in full and are set forth in the “Summary Compensation Table” above under the “Non-Equity Incentive Plan Compensation” column. The guaranteed portion of Mr. Grimmig’s bonus and Mr. Zagorski’s entire bonus for 2020, each of which was guaranteed pursuant to the respective terms of their respective employment agreements, are also shown in the “Summary Compensation Table” above under the “Bonus” column.

Outstanding Equity Awards at Fiscal Year End 2020

The following table provides information about outstanding equity awards held by each of our NEOs as of December 31, 2020. All awards were granted under the 2017 Equity Plan. Our equity incentive program was designed to ensure that our senior management and other employees, including our NEOs, help drive stockholder value, and stock options and restricted stock units constitute a meaningful part of our NEOs’ compensation. The 2017 Equity Plan is administered by our Compensation Committee, which has discretion, within the parameters of the 2017 Equity Plan, to determine the recipients, amounts and terms of awards. As of September 30, 2021, 14,439,214 shares of our common stock remained subject to outstanding options under our equity compensation

86

plans, including the 2017 Equity Plan, at a weighted average exercise price per share of $7.70, and 2,655,174 shares of our common stock remained subject to outstanding restricted stock units under our equity compensation plans, including the 2017 Equity Plan.

(1) The awards in this row consist of non-qualified stock options granted under our 2017 Equity Plan. The vesting schedule for this award provides that 25% of the options will vest on July 21, 2021, which is the one-year anniversary of Mr. Zagorski’s commencement of employment, and then at a rate of 6.25% per quarter over the next 12 quarters, subject in all cases to his continued employment through the applicable vesting date. Notwithstanding the foregoing, upon the completion of our IPO, the options that would have vested over the 12 months following the completion of the IPO vested, and the remaining options will vest on their original vesting schedule without regard to the aforementioned acceleration.

(2) The awards in this row consist of non-qualified stock options granted under our 2017 Equity Plan and are subject to the same time vesting criteria as the options described in note 1 above (including in respect of the accelerated vesting upon the completion of our IPO). These options were granted with an exercise price equal to two times the fair market value of a share of our common stock on the grant date, as determined by our board.

(3) The awards in this row consist of time vesting restricted stock units granted under our 2017 Equity Plan. 166,667 of these restricted stock units are subject to the same time vesting criteria as the options described in note 1 above (including in respect of the accelerated vesting upon the completion of our IPO). The remaining 86,581 restricted stock units vested on July 21, 2021.

(4) Represents the fair value of unvested restricted stock units as of December 31, 2020. Please refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates — Stock-Based Compensation” for more information regarding determinations of the fair value of equity interests.

(5) The awards in this row consist of non-qualified stock options granted under our 2017 Equity Plan, 25% of which vested on the first anniversary of the vesting commencement date, and the remainder of which have continued to vest at a rate of 6.25% per quarter. The grant date listed here does not correspond to the vesting commencement date of the options for Mr. Grimmig, which was March 30, 2020 (the date Mr. Grimmig commenced his employment with us).

87

(6) The awards in this row consist of non-qualified stock options granted under our 2017 Equity Plan that will vest upon the date that the Providence Investor has received cumulative cash proceeds in respect of its investment in the Company equal to two times its aggregate cash investment in the Company, which condition is expected to be satisfied upon the completion of this offering.

(7) The awards in this row consist of time vesting restricted stock units granted under our 2017 Equity Plan. Each award will vest on April 1, 2022, subject to the holder’s continued employment through that date.

(8) The award in this row consists of time vesting restricted stock units granted under our 2017 Equity Plan. This award will vest on December 31, 2022, subject to Mr. McLaughlin’s continued employment through that date.

(9) Mr. Gattinella had no outstanding equity awards as of December 31, 2020.

(10) The awards in this row consist of time vesting restricted stock units granted under our 2017 Equity Plan, which vest in two equal annual installments on the first and second anniversary of the grant date, subject to Ms. Desmond’s continued service as a member of our board of directors through such vesting date (unless Ms. Desmond’s service is terminated, with respect to the September 20, 2019 grant, by us without cause, or by reason of her death or disability, in which case all of Ms. Desmond’s unvested restricted stock units will accelerate and fully vest). The first installment of the awards granted on April 27, 2020 fully vested on April 27, 2021. The awards granted on September 20, 2019 fully vested on September 20, 2021.

(11) The awards in this row consist of time vesting restricted stock units granted under our 2017 Equity Plan, which vest on the first anniversary of the grant date, subject to Ms. Desmond’s continued service as a member of our board of directors through such anniversary (unless Ms. Desmond’s service is terminated by us without cause or by reason of her death or disability, in which case all of Ms. Desmond’s unvested restricted stock units will accelerate and fully vest). The awards fully vested on April 27, 2021.

Payments and Potential Payments upon Termination or Change in Control

Mark Zagorski

Mr. Zagorski’s employment agreement has a five-year term, which commenced July 21, 2020, and may also be terminated at any time prior to the expiration of the term by either party. The employment agreement provides for certain severance benefits. If prior to the expiration of the five-year term, Mr. Zagorski’s employment is terminated by us without “cause” or if he resigns his employment for “good reason” (as such terms are defined in his employment agreement), which we refer to as a “qualifying termination,” Mr. Zagorski is entitled to receive an amount equal to his annual base salary, payable in semi-monthly installments over 12 months, and also continued medical, dental and vision insurance coverage for 12 months at active employee rates. In addition, if Mr. Zagorski’s experiences a qualifying termination on or after the second anniversary of his commencement of employment, he will receive an amount equal to 50% of his target bonus payable in the same semi-monthly installments as the base salary component of his severance.

If Mr. Zagorski’s employment is terminated in a qualifying termination or by reason of his death or disability, the portion of his options and the time-based restricted stock units that would otherwise have vested between the date of termination and the twelve month anniversary of the date of termination will accelerate and fully vest, and such awards will also fully vest upon a change in control.

Matthew McLaughlin

Mr. McLaughlin’s employment agreement has a term that expires on January 1, 2023 unless the parties mutually agree to an extension, and may also be terminated at any time by either party. The employment agreement provides for certain severance benefits. Upon a qualifying termination (which for Mr. McLaughlin includes expiration of the term due to non-renewal by the parties), he is entitled to receive (i) an amount equal to the sum of his annual base salary plus his annual bonus paid at 100% of the target, payable in semi- monthly installments over 12 months, (ii) a prorated portion of his annual target bonus for the year in which termination occurs, determined based on the amount accrued by us through the date of his termination, (iii) continued medical, dental and vision insurance coverage for 12 months at active employee rates and (iv) continued payment or reimbursement for the life insurance premiums provided for under his employment agreement (including the income tax gross-up) for one year following his termination.

88

If Mr. McLaughlin is terminated in a qualifying termination or by reason of his death or disability, the portion of his unvested time-based options that would have vested in the 12 months following his termination will accelerate and vest, and the remaining unvested portion of his time-based options will be forfeited. Additionally, his performance-based options will remain outstanding for a one-year period following such termination and will vest if, during that period, the Providence Investor achieves the cash return performance hurdle described in note 7 to the “Outstanding Equity Awards at Fiscal Year End 2020” table set forth above.

If Mr. McLaughlin is terminated in a qualifying termination and Mr. McLaughlin agrees to provide any transition services reasonably requested by us, or if Mr. McLaughlin is terminated by reason of his death or disability, all of Mr. McLaughlin’s unvested restricted stock units will accelerate and fully vest.

Andy Grimmig

Mr. Grimmig’s employment agreement does not provide a fixed term and may be terminated at any time by either party. The employment agreement provides for certain severance benefits. Upon a qualifying termination, Mr. Grimmig is entitled to receive an amount equal to six months of his base salary, payable in semi-monthly installments over six months, and also continued medical, dental and vision insurance coverage for six months at active employee rates.

If prior to the first anniversary of the vesting commencement date of his option, Mr. Grimmig is terminated in a qualifying termination or by reason of his death or disability, a pro rata portion of his unvested time-based options that would have vested on the first anniversary of the vesting commencement date (based on completed months of service) will accelerate and vest, and the remaining unvested portion of his time-based options will be forfeited. Additionally, his performance-based options will remain outstanding for a six-month period following any termination of employment (other than a termination for cause) and will vest if, during that period, the Providence Investor achieves the cash return performance hurdle described in note 7 to the “Outstanding Equity Awards at Fiscal Year End 2020” table set forth above.

If Mr. Grimmig is terminated in a qualifying termination and Mr. Grimmig agrees to provide any transition services reasonably requested by us, or if Mr. Grimmig is terminated by reason of his death or disability, all of Mr. Grimmig’s unvested restricted stock units will accelerate and fully vest.

Wayne Gattinella

In connection with Mr. Gattinella’s departure from the Company, we agreed to provide Mr. Gattinella with cash severance payments equal to his annual base salary and target bonus in effect at the time of his departure payable in equal semi-monthly installments over the 12 month period following his separation. Mr. Gattinella also received the unpaid portion of his 2019 bonus, a pro-rated target bonus for 2020, a payment equal to twelve months of the employer contribution for his health insurance premiums as in effect prior to his separation, twelve months of parking reimbursement and twelve months of access to a co- working space. In addition, Mr. Gattinella was given an additional 12 months of vesting credit for his time-based stock options. On August 14, 2020 the Company notified Mr. Gattinella that it would exercise its right, pursuant to Mr. Gattinella’s Separation Agreement, to repurchase all of his outstanding stock options. That repurchase was completed on October 23, 2020.

Generally

In the event that we terminate an NEO for “cause”, or an NEO breaches a restrictive covenant by which he is bound, all of such NEO’s unvested and vested stock options and restricted stock units will be immediately cancelled and forfeited.

If we experience a “change in control” (as defined in the 2017 Equity Plan), time-based options and time-based RSUs granted under the 2017 Equity Plan will generally accelerate and vest in full. If performance- based options granted under the 2017 Equity Plan do not vest in a change in control, they will remain outstanding and be eligible to vest if the Providence Investor subsequently achieves the performance hurdle through payment of deferred proceeds and/or conversion of non-cash proceeds to cash. All awards granted under the 2021 Equity Plan will generally vest in full upon a “change in control” under the 2021 Equity Plan.

Retirement Benefits

We maintain a 401(k) plan for the benefit of our eligible employees, including the NEOs, under which participants are permitted to contribute a percentage of their compensation on a pre-tax basis, subject to limits in the U.S. Internal Revenue Code of 1986, as

89

amended (the “Code”). We make fully vested matching contributions under the 401(k) plan, subject to the discretion of our board of directors. Our NEOs are eligible to participate in the 401(k) plan on the same basis as our other employees.

We do not maintain any retirement plans other than the 401(k) plan.

New Equity Arrangements — Equity Incentive Plan

We currently maintain our 2017 Equity Plan, as described above. Following the completion of our IPO and the effectiveness of the 2021 Equity Plan, no further grants have been made under the 2017 Equity Plan, except that we will continue to grant awards under the 2017 Equity Plan to employees in certain non-U.S. jurisdictions until we receive all required governmental or tax authority approvals for the 2021 Equity Plan. To the extent that any such post-completion awards are made under our 2017 Equity Plan, they will count against the share reserve established under the 2021 Equity Plan. In connection with our IPO, our board of directors and our stockholders approved the 2021 Equity Plan, under which we may grant cash and equity incentive awards to eligible service providers in order to attract, motivate and retain the talent for which we compete. The material terms of the 2021 Equity Plan are summarized below.

Eligibility and Administration

Our employees, consultants and directors, and employees, consultants and directors of our subsidiaries, are eligible to receive awards under the 2021 Equity Plan. The 2021 Equity Plan is administered by our compensation committee, which may delegate its duties and responsibilities to other committees of our board of directors and/or officers (referred to collectively as the plan administrator below), subject to certain limitations that may be imposed under Section 16 of the Exchange Act and/or applicable law. The plan administrator has the authority to make all determinations and interpretations under, prescribe all forms for use with, and adopt rules for the administration of, the 2021 Equity Plan, subject to its express terms and conditions. The plan administrator also determines participants, award types and award amounts, and sets the terms and conditions of all awards under the 2021 Equity Plan, including any vesting conditions.

Limitation on Awards and Shares Available

The maximum number of shares of our common stock available for issuance under the 2021 Equity Plan is equal to the sum of (i) 30,000,000 shares of our common stock and (ii) an annual increase on the first day of each year beginning in 2022 and ending in and including 2031, equal to the lesser of (A) five percent (5)% of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year and (B) such lesser amount as determined by our compensation committee. The share reserve formula under the 2021 Equity Plan is intended to provide us with the continuing ability to grant equity awards to eligible employees, directors and consultants for the ten-year term of the 2021 Equity Plan.

Any shares covered by an award, or portion of an award, granted under the 2021 Equity Plan that expires or is forfeited, canceled, cash-settled, or otherwise terminated for any reason will again be available for the grant of awards under the 2021 Equity Plan. Additionally, any shares tendered or withheld to satisfy the grant or exercise price or tax withholding obligations pursuant to any award under the 2021 Equity Plan will again be available for issuance. The 2021 Equity Plan permits us to issue replacement awards to employees of companies acquired by us, but those replacement awards would not count against the share maximum listed above.

With respect to each of our fiscal years, the fair market value of shares subject to awards granted to any non-employee director (as of the grant date), and the cash paid to any non-employee director, may not exceed $750,000 in the aggregate for any such non-employee except in respect of a non-employee director’s initial service as a director, in which case the limitation is $1,000,000. The plan administrator may make exceptions to these limitations in extraordinary circumstances in its discretion.

Awards

The 2021 Equity Plan provides for the grant of stock options (including qualified incentive stock options, or “ISOs,” and nonqualified stock options, or “NSOs”), stock appreciation rights, or “SARs,” restricted stock, restricted stock units, or “RSUs,” dividend equivalents, and other stock or cash settled incentive awards. All awards under the 2021 Equity Plan will be set forth in award agreements, which will detail all terms and conditions of the awards, including any applicable vesting and payment terms and post- termination exercise limitations.

90

Terms and Conditions of Options and Stock Appreciation Rights. An “incentive stock option” is an option that meets the requirements of Section 422 of the Code, and a “non-qualified stock option” is an option that does not meet those requirements. A SAR is the right of a participant to a payment, in shares of common stock, or such other form determined by the plan administrator, equal to the amount by which the fair market value of a share of common stock on the exercise date exceeds the exercise price of the stock appreciation right. An option or SAR granted under the 2021 Equity Plan will be exercisable only to the extent that it is vested on the date of exercise. Each option and SAR will vest and become exercisable according to the terms and conditions determined by the plan administrator, which may include a period of required service, the achievement of performance goals determined or the occurrence of events, or any combination of the foregoing. Unless otherwise determined by the plan administrator, no option or SAR may be exercisable more than ten years from the grant date (or five years in the case of ISOs granted to certain significant stockholders). SARs may be granted to participants in tandem with options or separately.

The exercise price per share under each option and SAR granted under the 2021 Equity Plan may not be less than 100% of the fair market value of our common stock on the option grant date (or 110% in the case of ISOs granted to certain significant stockholders). The 2021 Equity Plan includes a general prohibition on the repricing of out-of-the-money options and SARs without stockholder approval.

Terms and Conditions of Restricted Stock and Restricted Stock Units. Restricted stock is an award of common stock on which certain restrictions are imposed over specified periods that subject the shares to a substantial risk of forfeiture. A restricted stock unit is a unit, equivalent in value to a share of common stock, credited by means of a bookkeeping entry in our books to a participant’s account, which is settled after vesting in stock or cash, as determined by the plan administrator. Subject to the provisions of the 2021 Equity Plan, our plan administrator will determine the terms and conditions of each award of restricted stock or restricted stock units, including the restricted period for all or a portion of the award, and the restrictions applicable to the award. Restricted stock and restricted stock units may vest based on a period of required service specified by our plan administrator, the achievement of performance goals determined by our plan administrator or the occurrence of events specified by our plan administrator, or any combination of the foregoing. Restricted stock units granted under the 2021 Equity Plan may receive dividend equivalents settled in shares of our common stock if determined by the plan administrator.

Dividend Equivalents. Dividend equivalents represent the right to receive the equivalent value of dividends paid on shares of our common stock and may be granted alone or in tandem with awards other than stock options or SARs. Dividend equivalents are credited as of dividend record dates during the period between the date an award is granted and the date such award vests, is exercised, is distributed or expires, as determined by the plan administrator.

Other Stock-Based Awards. The plan administrator may make other equity-based or equity-related awards not otherwise described by the terms of the 2021 Equity Plan. Vesting conditions of such other awards determined by the plan administrator may include a period of required service, the achievement of performance goals determined or the occurrence of events, or any combination of the foregoing.

Certain Transactions

The plan administrator has broad discretion to take action under the 2021 Equity Plan, as well as make adjustments to the terms and conditions of existing and future awards, to prevent the dilution or enlargement of the rights of plan participants in the event of certain transactions and events affecting our common stock, such as stock dividends, stock splits, mergers, acquisitions, consolidations and other significant corporate transactions. In the event of a Change in Control (as defined in the 2021 Equity Plan), to the extent that the surviving entity declines to continue, convert, assume or replace outstanding awards, then the plan administrator may provide that all such awards will terminate in exchange for cash or other consideration, or become fully vested and exercisable in connection with the transaction. Upon or in anticipation of a Change in Control, the plan administrator may cause any outstanding awards to terminate at a specified time in the future and give the participant the right to exercise such awards during a period of time determined by the plan administrator in its sole discretion. Individual award agreements may provide for additional accelerated vesting and payment provisions. All awards granted under the 2021 Equity Plan as of the date of this offering provide for full vesting upon a Change in Control.

Foreign Participants, Claw-Back Provisions, Transferability, and Participant Payments

The plan administrator may modify award terms, establish subplans and/or adjust other terms and conditions of awards, subject to the share limits described above, in order to facilitate grants of awards subject to the laws and/or stock exchange rules of countries

91

outside of the United States. All awards will be subject to the provisions of any forfeiture or recoupment policy implemented by us to the extent set forth in such policy and/or in the applicable award agreement. With limited exceptions for certain beneficiary designations and the laws of descent and distribution, awards under the 2021 Equity Plan are generally non- transferable, and are exercisable only by the participant. With regard to tax withholding, exercise price and purchase price obligations arising in connection with awards under the 2021 Equity Plan, the plan administrator may, in its discretion, accept cash or check, provide for net withholding of shares, allow shares of our common stock that meet specified conditions to be repurchased, allow a “market sell order” or such other consideration as it deems suitable.

Plan Amendment and Termination

Our board of directors may amend or terminate the 2021 Equity Plan at any time; however, except in connection with certain changes in our capital structure, stockholder approval is required for any amendment that increases the number of shares available under the 2021 Equity Plan. No award may be granted pursuant to the 2021 Equity Plan after the tenth anniversary of the 2021 Equity Plan’s effective date. However, the expiration of the 2021 Equity Plan would have no effect on outstanding awards previously granted.

New Equity Arrangements — Employee Stock Purchase Plan

In connection with our IPO, our board of directors and our stockholders approved the ESPP. The material terms of the ESPP are summarized below.

Shares Available; Administration

The aggregate number of shares of our common stock initially reserved for issuance under our ESPP is equal to the sum of (i) 3,000,000 shares of our common stock and (ii) an annual increase on the first day of each year beginning in 2022 and ending in and including 2031, equal to the lesser of (A) one percent (1)% of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year and (B) such lesser amount as determined by our board of directors. Our board of directors and the compensation committee have authority to interpret the terms of the ESPP and determine eligibility of participants. The compensation committee of our board of directors is the initial administrator of the ESPP.

Eligibility

Our employees, other than employees who, immediately after the grant of a right to purchase common stock under the ESPP, own (directly or through attribution) stock possessing 5% or more of the total combined voting power or value of our common or other class of stock, are eligible to participate in the ESPP. However, consistent with Section 423 of the Code, the plan administrator may provide that other groups of employees, including without limitation those who do not meet designated service requirements or those whose participation would be in violation of applicable foreign laws, will not be eligible to participate in the ESPP.

Grant of Rights

The ESPP is intended to qualify under Section 423 of the Code and shares of our common stock will be offered under the ESPP during offering periods. The length of the offering periods under the ESPP will be determined by the plan administrator and may be up to 27 months long. Employee payroll deductions will be used to purchase shares on each purchase date during an offering period. The purchase dates for each offering period will be the final trading day in each offering period. Offering periods under the ESPP will commence when determined by the plan administrator. The plan administrator may, in its discretion, modify the terms of future offering periods. We do not expect that any offering periods will commence under the ESPP at the completion of this offering.

The ESPP permits participants to purchase common stock through payroll deductions of up to a fixed dollar amount or percentage of their eligible compensation, which includes a participant’s gross base compensation for services to us. The plan administrator will establish a maximum number of shares that may be purchased by a participant during any offering period. In addition, no employee is permitted to accrue the right to purchase stock under the ESPP at a rate in excess of $25,000 worth of shares during any calendar year during which such a purchase right is outstanding (based on the fair market value per share of our common stock as of the day the purchase right was granted).

On the first trading day of each offering period, each participant will be granted an option to purchase shares of our common stock. The option will expire at the end of the applicable offering period and will be exercised on the last day of such offering period to the extent of the payroll deductions accumulated during the offering period. The purchase price of the shares will be determined by

92

the plan administrator and shall be at least 85% of the lesser of (A) the fair market value of our common stock on the first trading day of the offering period, and (B) the fair market value on the purchase date, which will be the final trading day of the offering period. Participants may voluntarily end their participation in the ESPP prior to the end of the applicable offering period, and will be paid their accrued payroll deductions that have not yet been used to purchase shares of common stock. Participation will end automatically upon a participant’s termination of employment.

A participant is not permitted to transfer rights granted under the ESPP other than by will, the laws of descent and distribution or as otherwise provided under the ESPP.

Certain Transactions

In the event of certain transactions and events affecting our common stock, such as stock dividends, stock splits, mergers, acquisitions, consolidations and other significant corporate transactions, the plan administrator will make equitable adjustments to the ESPP and outstanding ESPP purchase rights. In addition, in the event of a Change in Control, the plan administrator may take whatever action it deems necessary or appropriate, including (i) shortening any offering period then in progress so that the purchase date is on or prior to the date of the Change in Control transaction, (ii) shortening any offering period then in progress and refunding any amounts accumulated in a participant’s account for that period, (iii) cancelling all outstanding purchase rights as of the date of the Change in Control transaction and paying each participant an amount equal to the difference between the Change in Control share price and the purchase price for that offering period, or (iv) granting a substitute right to purchase shares.

Plan Amendment

Our board of directors or the plan administrator may amend, suspend, discontinue or terminate the ESPP at any time. However, stockholder approval of any amendment to the ESPP will be obtained for any amendment that increases the aggregate number or changes the type of shares that may be sold pursuant to rights under the ESPP, or changes the corporations or classes of corporations the employees of which are eligible to participate in the ESPP.

PRINCIPAL AND SELLING STOCKHOLDERS

The following table sets forth information as of November 1, 2021 with respect to the ownership of our common stock by:

● each person known by us to own beneficially more than five percent of our common stock;

● each of the selling stockholders;

● each of our directors;

● each of our named executive officers; and

● all of our current executive officers and directors as a group.

The amounts and percentages of shares beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Percentage computations are based on 158,629,136 shares of our common stock outstanding as of November 1, 2021.

95

Except as otherwise indicated in the footnotes to the table, each of the beneficial owners listed has, to our knowledge, sole voting and investment power with respect to the indicated shares of common stock. Unless otherwise set forth in the footnotes to the table, the address for each listed stockholder is 233 Spring Street, New York, NY 10013.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Policies and Procedures for Related Person Transactions

Our board of directors has approved policies and procedures with respect to the review and approval of certain transactions between us and a “Related Person,” or a “Related Person Transaction,” which we refer to as our “Related Person Transaction Policy.” Pursuant to the terms of the Related Person Transaction Policy, our board of directors, acting through our Audit Committee, must review and decide whether to approve or ratify any Related Person Transaction. Any Related Person Transaction is required to be reported to our legal department, which will then determine whether it should be submitted to our Audit Committee for consideration. The Audit Committee must then review and decide whether to approve any Related Person Transaction.

For the purposes of the Related Person Transaction Policy, a “Related Person Transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we (including any of our subsidiaries) were, are or will be a participant and the amount involved exceeds $120,000, and in which any Related Person had, has or will have a direct or indirect interest.

A “Related Person,” as defined in the Related Person Transaction Policy, means any person who is, or at any time since the beginning of our last fiscal year was, a director or executive officer of DoubleVerify or a nominee to become a director of DoubleVerify; any person who is known to be the beneficial owner of more than five percent of our common stock; any immediate family member of any of the foregoing persons, including any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law of the director, executive officer, nominee or more than five percent beneficial owner, and any person (other than a tenant or employee) sharing the household of such director, executive officer, nominee or more than five percent beneficial owner; and any firm, corporation or other entity in which any of the foregoing persons is a general partner or, for other ownership interests, a limited partner or other owner in which such person has a beneficial ownership interest of ten percent or more.

Transactions with Providence and its Affiliates

Expense Reimbursement Agreement

On September 20, 2017, the Company and DoubleVerify Inc. entered into an Expense Reimbursement Agreement (the “Expense Agreement”) with Providence, pursuant to which we agreed to reimburse Providence for reasonable out-of-pocket expenses (including travel and lodging) and costs, expenses and disbursements relating to regulatory compliance or similar matters (including audit expenses) incurred for rendering consulting and management and advisory services to us and our affiliates, including financial and strategic planning and other services as mutually agreed by the parties to the Expense Agreement. We reimbursed Providence $0.1 million, $0.2 million and $0.2 million in 2020, 2019 and 2018, respectively, pursuant to the Expense Agreement. Pursuant to the terms of the Expense Agreement, the Expense Agreement automatically terminated upon the completion of our IPO.

Other

From time to time and in the ordinary course of business, we may purchase goods and services from other Providence portfolio companies. We did not incur expenses associated with these related party transactions in the nine months ended September 30, 2021 or any of the years ended December 31, 2020, 2019 and 2018.

Relationship with Providence

Stockholders Agreements

In connection with the Private Placement, we entered into an amended and restated stockholders agreement, dated as of November 18, 2020, with the Providence Investor, Blumberg Capital, the Private Placement Investors and certain other stockholders of the Company (the “Old Stockholders Agreement”). The Old Stockholders Agreement contained restrictions on the ability of the parties thereto to freely transfer shares of our common stock. The parties thereto also agreed to vote their shares of our common stock on certain matters presented to the stockholders, including in favor of all directors nominated by the board of directors for election. In addition, the Providence Investor was entitled under the Old Stockholders Agreement to nominate for election, fill vacancies and appoint at least six of eight members of the board of directors, any of which could in the Providence Investor’s discretion be an independent director. The Providence Investor also had discretion to adjust the number of directors on the board, as well as certain

99

consent rights. The Old Stockholders Agreement granted the parties thereto piggyback registration rights in connection with a registered offering of our common stock in which the Providence Investor participated (including the IPO).

The Old Stockholders Agreement automatically terminated on the date the SEC declared effective the IPO registration statement and was replaced with a new stockholder’s agreement (the “Stockholder’s Agreement”) between the Company and the Providence Investor. The Stockholder’s Agreement governs the relationship between Providence and us following our IPO, including matters related to our corporate governance, such as Board nomination rights and information rights. The Stockholder’s Agreement grants Providence the right to designate for nomination for election a number of Providence Designees equal to: (i) at least a majority of the total number of directors comprising our board of directors at such time as long as Providence owns at least 50% of the outstanding shares of our common stock; (ii) at least 40% of the total number of directors comprising our board of directors at such time as long as Providence owns at least 40% but less than 50% of the outstanding shares of our common stock; (iii) at least 30% of the total number of directors comprising our board of directors at such time as long as Providence owns at least 30% but less than 40% of the outstanding shares of our common stock; (iv) at least 20% of the total number of directors comprising our board of directors at such time as long as Providence owns at least 20% but less than 30% of the outstanding shares of our common stock; and (v) at least 5% of the total number of directors comprising our board of directors at such time as long as Providence owns at least 5% but less than 20% of the outstanding shares of our common stock. For purposes of calculating the number of Providence Designees that Providence is entitled to nominate pursuant to the formula outlined above, any fractional amounts will be rounded to the nearest whole number (but not below one so long as Providence owns at least 5% of the outstanding shares of our common stock) and the calculation will be made on a pro forma basis after taking into account any increase in the size of our board of directors.

Registration Rights Agreement

In connection with our IPO, we entered into a registration rights agreement with the Providence Investor and certain of our other existing stockholders (the “Registration Rights Agreement”). The Registration Rights Agreement grants to Providence and its permitted assigns, customary demand registration rights and piggyback registration rights, and to such other existing stockholders and their permitted assigns, customary piggyback registration rights, in each case subject to customary terms and conditions.

Relationships with Directors and Executive Officers

Director Indemnification Agreements

We have entered into an indemnification agreement with each of our directors. The indemnification agreements provide our directors with contractual rights to the indemnification and expense advancement rights provided under our amended and restated bylaws, as well as contractual rights to additional indemnification as provided in the indemnification agreements. See “Description of Capital Stock — Limitations on Liability and Indemnification.”

Registration Rights Agreement

In connection with our IPO, we entered into the Registration Rights Agreement. Mark Zagorski, Nicola Allais, The McLaughlin Family Trust (for which Matthew McLaughlin is a trustee), Andy Grimmig, the Laura B. Desmond Revocable Trust (for which Laura B. Desmond is trustee) and Teri L. List are parties to the Registration Rights Agreement. Each of Mr. Zagorski, Mr. Allais, Mr. McLaughlin, Mr. Grimmig, Ms. Desmond and Ms. List is a director and/or executive officer of the Company. See “— Relationship with Providence — Registration Rights Agreement.”

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock is a summary of the material terms of our amended and restated certificate of incorporation and amended and restated bylaws. Reference is made to the more detailed provisions of, and the descriptions are qualified in their entirety by reference to, these documents, which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part, and applicable law.

General

Our authorized capital stock currently consists of 1,000,000,000 shares of common stock, par value $0.001 per share and 100,000,000 shares of undesignated preferred stock, par value $0.01 per share.

As of September 30, 2021, there were 158,474,240 shares of our common stock outstanding, not including 17,094,388 shares of our common stock issuable upon exercise of outstanding stock options and vesting of outstanding restricted stock units as of September 30, 2021, and no shares of our preferred stock outstanding.

Common Stock

Holders of our common stock are entitled:

● to cast one vote for each share held of record on all matters submitted to a vote of the stockholders;

● to receive, on a pro rata basis, dividends and distributions, if any, that our board of directors may declare out of legally available funds, subject to preferences that may be applicable to preferred stock, if any, then outstanding; and

● upon our liquidation, dissolution or winding-up, to share equally and ratably in any assets remaining after the payment of all debt and other liabilities, subject to the prior rights, if any, of holders of any outstanding shares of preferred stock.

Our ability to pay dividends on our common stock is subject to the discretion of our board of directors. See “Dividend Policy.”

The holders of our common stock do not have any preemptive, cumulative voting, subscription, conversion, redemption or sinking fund rights. The common stock is not subject to future calls or assessments by us. The rights and privileges of holders of our common stock are subject to any series of preferred stock that we may issue in the future, as described below.

Our common stock is listed on the NYSE under the symbol “DV.”

As of September 30, 2021, we had 158,474,240 shares of common stock outstanding and 186 holders of record of our common stock.

Preferred Stock

Under our amended and restated certificate of incorporation, our board of directors has the authority, without further action by our stockholders, to issue up to 100,000,000 shares of preferred stock in one or more series and to fix the voting powers, designations, preferences and the relative participating, optional or other special rights and qualifications, limitations and restrictions of each series, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, liquidation preferences and the number of shares constituting any series. As of September 30, 2021, no shares of our authorized preferred stock are issued or outstanding. Because the board of directors has the power to establish the preferences and rights of the shares of any additional series of preferred stock, it may afford holders of any preferred stock preferences, powers and rights, including voting and dividend rights, senior to the rights of holders of our common stock, which could adversely affect the holders of the common stock and could delay, discourage or prevent a takeover of us even if a change of control of our company would be beneficial to the interests of our stockholders.

Annual Stockholders Meeting

Our amended and restated bylaws provide that annual stockholders meetings will be held at a date, time and place, if any, as exclusively selected by our board of directors. To the extent permitted under applicable law, we may conduct meetings by remote communications, including by webcast.

102

Voting

The affirmative vote of a plurality in voting power of the shares of our capital stock present, in person or by proxy, at the meeting and entitled to vote on the election of directors will decide the election of any directors, and the affirmative vote of a majority in voting power of the shares of our capital stock present, in person or by proxy, at the meeting and entitled to vote at any annual or special meeting of stockholders will decide all other matters voted on by stockholders, unless the question is one upon which, by express provision of law, under our amended and restated certificate of incorporation, or under our amended and restated bylaws, a different vote is required, in which case such provision will control. Stockholders do not have the right to cumulate their votes for the election of directors.

Board Designation Rights

Pursuant to the Stockholder’s Agreement, Providence has specified board designation and other rights. See “Certain Relationships and Related Party Transactions — Relationship with Providence — Stockholders Agreements.”

Anti-Takeover Effects of Our Certificate of Incorporation and Bylaws

The provisions of our amended and restated certificate of incorporation and amended and restated bylaws summarized below may have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that you might consider in your best interest, including an attempt that might result in your receipt of a premium over the market price for your shares. These provisions are also designed, in part, to encourage persons seeking to acquire control of us to first negotiate with our board of directors, which could result in an improvement of their terms.

Authorized but Unissued Shares of Common Stock. Our shares of authorized and unissued common stock are available for future issuance without additional stockholder approval. While our authorized and unissued shares are not designed to deter or prevent a change of control, under some circumstances we could use the additional shares to create voting impediments or to frustrate persons seeking to effect a takeover or otherwise gain control by, for example, issuing those shares in private placements to purchasers who might side with our board of directors in opposing a hostile takeover bid.

Authorized but Unissued Shares of Preferred Stock. Under our amended and restated certificate of incorporation, our board of directors has the authority, without further action by our stockholders, to issue up to 100,000,000 shares of preferred stock in one or more series and to fix the voting powers, designations, preferences and the relative participating, optional or other special rights and qualifications, limitations and restrictions of each series, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, liquidation preferences and the number of shares constituting any series. The existence of authorized but unissued preferred stock could reduce our attractiveness as a target for an unsolicited takeover bid since we could, for example, issue shares of preferred stock to parties who might oppose such a takeover bid or shares that contain terms the potential acquiror may find unattractive. This may have the effect of delaying or preventing a change of control, may discourage bids for the common stock at a premium over the market price of the common stock, and may adversely affect the market price of, and the voting and other rights of the holders of, our common stock.

Classified Board of Directors. In accordance with the terms of our amended and restated certificate of incorporation, our board of directors is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. Under our amended and restated certificate of incorporation, our board of directors consists of such number of directors as may be determined from time to time by resolution of the board of directors, but in no event may the number of directors be less than one. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. Our amended and restated certificate of incorporation also provides that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by the affirmative vote of a majority of our directors then in office, even if less than a quorum, or by a sole remaining director, subject to the Stockholder’s Agreement with respect to the director designation rights of Providence. Any director elected to fill a vacancy will hold office until such director’s successor shall have been duly elected and qualified or until such director’s earlier death, resignation or removal. Our classified board of directors could have the effect of delaying or discouraging an acquisition of us or a change in our management.

Removal of Directors. Our amended and restated certificate of incorporation provides that directors may be removed with or without cause at any time upon the affirmative vote of holders of at least a majority in voting power of the outstanding shares of

103

capital stock then entitled to vote at an election of directors until Providence ceases to beneficially own at least 40% of the outstanding shares of our common stock. Thereafter, our amended and restated certificate of incorporation provides that directors may be removed only for cause upon the affirmative vote of holders of at least 662∕3% in voting power of the outstanding shares of capital stock then entitled to vote at an election of directors.

Special Meetings of Stockholders. Our amended and restated certificate of incorporation provides that a special meeting of stockholders may be called only by the Chairperson of our board of directors, or if there is no Chairperson, then by our Chief Executive Officer, or by a resolution adopted by a majority of our board of directors. Special meetings may also be called by our corporate secretary at the request of the holders of at least a majority in voting power of the outstanding shares of our capital stock until Providence ceases to beneficially own at least 40% of the outstanding shares of our common stock. Thereafter, stockholders are not permitted to call a special meeting of stockholders.

Stockholder Advance Notice Procedure. Our amended and restated bylaws establish an advance notice procedure for stockholders to make nominations of candidates for election as directors or to bring other business before an annual meeting of our stockholders. The amended and restated bylaws provide that any stockholder wishing to nominate persons for election as directors at, or bring other business before, an annual meeting must deliver to our corporate secretary a written notice of the stockholder’s intention to do so. These provisions may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed. These provisions may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company. To be timely, the stockholder’s notice must be delivered to our corporate secretary at our principal executive offices not less than 90 days nor more than 120 days before the first anniversary date of the annual meeting for the preceding year; provided, however, that in the event that the annual meeting is set for a date that is more than 30 days before or more than 70 days after the first anniversary date of the preceding year’s annual meeting, a stockholder’s notice must be delivered to our corporate secretary not earlier than 120 days prior to the meeting and not later than the later of (x) the close of business on the 90th day prior to the meeting or (y) the close of business on the 10th day following the day on which a public announcement of the date of the meeting is first made by us.

No Stockholder Action by Written Consent. Our amended and restated certificate of incorporation provides that stockholder action may be taken only at an annual meeting or special meeting of stockholders; provided that stockholder action may be taken by written consent in lieu of a meeting until Providence ceases to beneficially own at least 40% of the outstanding shares of our common stock.

Amendments to Certificate of Incorporation and Bylaws. Our amended and restated certificate of incorporation provides that our amended and restated certificate of incorporation may be amended by both the affirmative vote of a majority of our board of directors and the affirmative vote of the holders of a majority in voting power of the outstanding shares of our capital stock then entitled to vote at any annual or special meeting of stockholders; provided that, at any time when Providence beneficially owns less than 40% of the outstanding shares of our common stock, specified provisions of our amended and restated certificate of incorporation may not be amended, altered or repealed unless the amendment is approved by the affirmative vote of the holders of at least 662∕3% in voting power of the outstanding shares of our capital stock then entitled to vote at any annual or special meeting of stockholders, including the provisions governing:

● liability and indemnification of directors;

● corporate opportunities;

● the ability of stockholders to act by written consent;

● the ability of stockholders to call a special meeting;

● removal of directors for cause; and

● our classified board of directors.

In addition, our amended and restated bylaws may be amended, altered or repealed, or new bylaws may be adopted, by the affirmative vote of a majority of the board of directors, or by the affirmative vote of our stockholders (x) as long as Providence beneficially owns at least 40% of the outstanding shares of our common stock, by at least a majority, and (y) thereafter, by at least

104

662∕3%, in voting power of the outstanding shares of our capital stock then entitled to vote at any annual or special meeting of stockholders.

These provisions make it more difficult for any person to remove or amend any provisions in our amended and restated certificate of incorporation and amended and restated bylaws that may have an anti- takeover effect.

Delaware Anti-Takeover Law.In general, Section 203 of the DGCL prohibits a publicly held Delaware corporation from engaging in business combinations, such as mergers, sales and leases of assets, issuances of securities and similar transactions by a corporation or subsidiary with an interested stockholder including a person or group who beneficially owns 15% or more of the corporation’s voting stock for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Section 203 permits corporations, in their certificate of incorporation, to opt out of the protections of Section 203. Our amended and restated certificate of incorporation provides that we have elected not to be subject to Section 203 of the DGCL for so long as Providence owns, directly or indirectly, at least 15% of the then-outstanding shares of our common stock. From and after the date that Providence ceases to own, directly or indirectly, at least 15% of the then-outstanding shares of our common stock, we will be governed by Section 203.

Limitations on Liability and Indemnification

Our amended and restated certificate of incorporation contains provisions relating to the liability of directors. These provisions eliminate a director’s personal liability for monetary damages resulting from a breach of fiduciary duty, except in circumstances involving:

● any breach of the director’s duty of loyalty;

● acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law;

● unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions; or

● any transaction from which the director derives an improper personal benefit.

The principal effect of the limitation on liability provision is that a stockholder is unable to prosecute an action for monetary damages against a director unless the stockholder can demonstrate a basis for liability for which indemnification is not available under the DGCL. These provisions, however, should not limit or eliminate our rights or any stockholder’s rights to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of director’s fiduciary duty. These provisions do not alter a director’s liability under federal securities laws. The inclusion of this provision in our amended and restated certificate of incorporation may discourage or deter stockholders or management from bringing a lawsuit against directors for a breach of their fiduciary duties, even though such an action, if successful, might otherwise have benefited us and our stockholders. In addition, your investment may be adversely affected to the extent we pay costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

Our amended and restated certificate of incorporation and our amended and restated bylaws require us to indemnify and advance expenses to our directors and officers to the fullest extent not prohibited by the DGCL and other applicable law, except in the case of a proceeding instituted by the director without the approval of our board of directors. Our amended and restated certificate of incorporation and our amended and restated bylaws provide that we are required to indemnify our directors and executive officers, to the fullest extent permitted by law, for all judgments, fines, settlements, legal fees and other expenses incurred in connection with pending or threatened legal proceedings because of the director’s or officer’s positions with us or another entity that the director or officer serves at our request, subject to various conditions, and to advance funds to our directors and officers to enable them to defend against such proceedings. To receive indemnification, the director or officer must have been successful in the legal proceeding or have acted in good faith and in what was reasonably believed to be a lawful manner in our best interest and, with respect to any criminal proceeding, have had no reasonable cause to believe his or her conduct was unlawful.

We have entered into an indemnification agreement with each of our directors. The indemnification agreements provide our directors with contractual rights to the indemnification and expense advancement rights provided under our amended and restated bylaws, as well as contractual rights to additional indemnification as provided in the indemnification agreements.

105

Corporate Opportunities

Our amended and restated certificate of incorporation provides that we, on our behalf and on behalf of our subsidiaries, renounce any interest or expectancy in, or in being offered an opportunity to participate in, corporate opportunities that are from time to time presented to Providence or any of its affiliates, directors, officers, employees, members or partners, even if the opportunity is one that we or our subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so. Neither Providence nor any of its affiliates, directors, officers, employees, members or partners are generally liable to us or any of our subsidiaries for breach of any fiduciary or other duty, as a director or otherwise, by reason of the fact that such person pursues or acquires such corporate opportunity, directs such corporate opportunity to another person or fails to present such corporate opportunity, or information regarding such corporate opportunity, to us or our subsidiaries unless, in the case of any such person who is a director or officer of DoubleVerify, such corporate opportunity is expressly offered to such director or officer in writing solely in his or her capacity as a director or officer of DoubleVerify. To the fullest extent permitted by law, by becoming a stockholder in our company, stockholders will be deemed to have notice of and consented to this provision of our amended and restated certificate of incorporation. Currently, Providence does not have any portfolio companies that would be considered direct competitors to DoubleVerify with respect to ad verification or similar software services.

Choice of Forum

Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternate forum, the Court of Chancery of the State of Delaware will, to the fullest extent provided by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our current or former directors, officers, other employees, agents or stockholders, (iii) any action or proceeding asserting a claim against us arising under the DGCL or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware (including, without limitation, any action asserting a claim arising out of or pursuant to our amended and restated certificate of incorporation or our amended and restated bylaws) or (iv) any action or proceeding asserting a claim against us that is governed by the internal affairs doctrine, in each case, subject to such Court of Chancery of the State of Delaware having personal jurisdiction over the indispensable parties named as defendants; provided that, the exclusive forum provision does not apply to any action or proceeding brought to enforce any liability or duty created by the Exchange Act or any other action or proceeding asserting a claim for which the federal courts have exclusive jurisdiction; provided further that, if and only if the Court of Chancery of the State of Delaware dismisses any such action or proceeding for lack of subject matter jurisdiction, such action or proceeding may be brought in another state or federal court sitting in the State of Delaware. Furthermore our amended and restated certificate of incorporation also provides that unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. By becoming a stockholder in our company, you will be deemed to have notice of and have consented to the provisions of our amended and restated certificate of incorporation related to choice of forum.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC.

SHARES AVAILABLE FOR FUTURE SALE

Our common stock is listed on the NYSE under the symbol “DV”. Sales of substantial amounts of our common stock in the public market could adversely affect prevailing market prices of our common stock. Some shares of our common stock will not be available for sale for a certain period of time after this offering because they are subject to contractual and legal restrictions on resale, some of which are described below. Sales of substantial amounts of common stock in the public market after these restrictions lapse, or the perception that these sales could occur, could adversely affect the prevailing market price and our ability to raise equity capital in the future.

Sales of Restricted Securities

As of November 1, 2021, we had 158,629,136 shares of common stock outstanding. Following the completion of this offering, a portion of these shares will be immediately tradable without restriction under the Securities Act except for any shares held by “affiliates,” as that term is defined in Rule 144. We have filed a registration statement on Form S-8 under the Securities Act to register the shares of common stock to be issued under our equity compensation plans and, as a result, all shares of common stock acquired upon exercise of stock options or vesting of restricted stock units granted under these plans are also freely tradable under the Securities Act, subject to the terms of the lock-up agreements entered into in connection with this offering. As of November 1, 2021, there were stock options outstanding to purchase a total of 14,274,607 shares of our common stock and 2,696,762 outstanding restricted stock units (each restricted stock unit representing the right to receive one share of common stock upon vesting). As of November 1, 2021, 33,000,000 shares of our common stock were reserved for issuance under the 2021 Equity Plan and the ESPP, of which 2,290,849 shares were subject to outstanding awards, and 14,680,520 shares were reserved for issuance under the 2017 Equity Plan, all of which were subject to outstanding awards.

The remaining shares of our common stock outstanding and held by our existing stockholders as of the completion of this offering will be “restricted securities” within the meaning of Rule 144. Restricted securities may be sold in the public market only if they are registered under the Securities Act or are sold pursuant to an exemption from registration under Rule 144 or Rule 701, which are summarized below. Subject to the lock-up agreements described below, shares held by our affiliates that are not restricted securities may be sold subject to compliance with Rule 144 without regard to the prescribed one-year holding period under Rule 144.

Stock Options and Restricted Stock Units

We have filed a registration statement on Form S-8 under the Securities Act to register the shares of common stock to be issued under our equity compensation plans and, as a result, all shares of common stock acquired upon exercise of stock options and vesting of restricted stock units and other equity-based awards granted under these plans are, subject to the terms of the lock-up agreements entered into in connection with this offering, also freely tradable under the Securities Act. A total of 14,274,607 shares and 2,696,762 shares of common stock are subject to outstanding stock options and restricted stock units, respectively, previously granted under our equity compensation plans as of November 1, 2021, and an additional 30,455,379 shares of common stock are available for grants of additional equity awards under equity compensation plans adopted in connection with our IPO.

Lock-up Agreements

In connection with this offering, we, our executive officers and directors and the selling stockholders will agree, subject to certain exceptions described herein, not to sell, transfer or dispose of or hedge, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for shares of our common stock for a period of 90 days after the date of this prospectus except with the prior written consent of J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC.

Registration Rights Agreement

Providence and its permitted assigns have the right to require us to register shares of common stock for resale in some circumstances. See “Certain Relationships and Related Party Transactions — Relationship with Providence — Registration Rights Agreement.”

Rule 144

In general, under Rule 144, as currently in effect, a person (or persons whose shares are aggregated) who is not deemed to be or have been one of our affiliates for purposes of the Securities Act at any time during 90 days preceding a sale and who has beneficially

107

owned the shares proposed to be sold for at least six months, including the holding period of any prior owner other than an affiliate, is entitled to sell such shares without registration, subject to compliance with the public information requirements of Rule 144. If such a person has beneficially owned the shares proposed to be sold for at least one year, including the holding period of a prior owner other than an affiliate, then such person is entitled to sell such shares without complying with any of the requirements of Rule 144.

In general, under Rule 144, as currently in effect, our affiliates or persons selling shares on behalf of our affiliates, who have met the six-month holding period for beneficial ownership of “restricted shares” of our common stock, are entitled to sell within any three-month period, a number of shares that does not exceed the greater of:

● 1% of the number of shares of our common stock then outstanding, which, as of November 1, 2021, will equal approximately 1,586,291 shares immediately after this offering; and

● the average reported weekly trading volume of our common stock on the NYSE during the four calendar weeks preceding the date of filing a Notice of Proposed Sale of Securities Pursuant to Rule 144 with respect to the sale.

Sales under Rule 144 by our affiliates or persons selling shares on behalf of our affiliates are also subject to certain manner of sale provisions and notice requirements and to the availability of current public information about us. The sale of these shares, or the perception that sales will be made, could adversely affect the price of our common stock after this offering because a great supply of shares would be, or would be perceived to be, available for sale in the public market.

Rule 701

Any of our employees, officers or directors who acquired shares under a written compensatory plan or contract may be entitled to sell them in reliance on Rule 701. Rule 701 permits affiliates to sell their Rule 701 shares under Rule 144 without complying with the holding period requirements of Rule 144. Rule 701 further provides that non-affiliates may sell these shares in reliance on Rule 144 without complying with the holding period, public information, volume limitation or notice provisions of Rule 144.

DESCRIPTION OF CERTAIN INDEBTEDNESS

Prior Credit Facilities

On July 31, 2018, our indirect subsidiary DoubleVerify Inc., as borrower, and our direct subsidiary DoubleVerify MidCo, Inc., as guarantor, entered into an amended and restated credit agreement (the “Prior Credit Agreement”) with the lenders party thereto, Capital One, National Association, as administrative agent, letter of credit issuer, swing lender and a lead arranger, and Antares Capital LP, as a lead arranger, providing for senior secured credit facilities comprised of (i) a senior secured term loan facility in an aggregate principal amount of $55.0 million (the “Prior Term Loan Facility”), (ii) a senior secured delayed draw term loan facility in an aggregate principal amount of $20.0 million (the “Prior DDTL Facility”) and (iii) a revolving credit facility in an aggregate principal amount of $20.0 million (with a letter of credit facility of up to $5.0 million as a sublimit) (the “Prior Revolving Credit Facility” and, together with the Prior Term Loan Facility and the Prior DDTL Facility, the “Prior Credit Facilities”).

On October 1, 2020, DoubleVerify Inc. repaid all amounts outstanding under the Prior Credit Facilities with borrowings under the New Revolving Credit Facility.

New Revolving Credit Facility

On October 1, 2020, DoubleVerify Inc., as borrower (the “Borrower”), and DoubleVerify MidCo, Inc., as guarantor (“DV Midco”), entered into an amendment and restatement agreement with the banks and other financial institutions party thereto, as lenders, and Capital One, National Association, as administrative agent, letter of credit issuer and swing lender, and others, to (i) amend and restate the Prior Credit Agreement (the Prior Credit Agreement, as amended and restated on October 1, 2020, the “Credit Agreement”) and (ii) replace the Prior Credit Facilities with a new senior secured revolving credit facility (the “New Revolving Credit Facility”) in an aggregate principal amount of $150.0 million (with a letter of credit facility of up to $15.0 million as a sublimit). Subject to certain terms and conditions (including pro forma compliance with a maximum total net leverage ratio of 3.50:1.00), the Borrower is entitled to request term loan facilities, or increases in the revolving credit commitments up to $100.0 million, under the New Revolving Credit Facility.

As of September 30, 2021, there are no amounts outstanding under the New Revolving Credit Facility. The final maturity of the New Revolving Credit Facility is October 1, 2025 (the “Maturity Date”).

Interest Rates and Fees

The loans under the New Revolving Credit Facility, at the Borrower’s option, bear interest at the following rates:

● in the case of Eurodollar loans, for each day during each interest period with respect thereto, a rate per annum equal to the Eurodollar rate determined for such day plus an applicable margin ranging from 2.00% to 2.75% per annum (depending on the total net leverage ratio of the Credit Group);

● in the case of ABR loans, a rate per annum equal to the ABR plus an applicable margin ranging from 1.00% to 1.75% per annum (depending on the total net leverage ratio of the Credit Group).

The Eurodollar rate is calculated based on the ratio of the Eurodollar base rate, which is determined by reference to LIBOR, over the Eurocurrency reserve requirements. The Eurodollar rate is subject to a “floor” of 0.75% per annum.

ABR is equal to the highest of the (i) the rate announced by the administrative agent as its prime commercial lending rate, (ii) the federal funds rate (which shall not be less than 0% per annum) plus 0.50%, and (iii) the one-month Eurodollar rate plus 1.00%.

The New Revolving Credit Facility bears a commitment fee ranging from 0.25% to 0.40% per annum (depending on the total net leverage ratio of the Credit Group), payable quarterly in arrears commencing on January 1, 2021 and on the first day of each calendar quarter occurring thereafter prior to the Maturity Date, and on the Maturity Date, based on the utilization of the New Revolving Credit Facility, and customary letter of credit fees.

109

Prepayments

The revolving credit loans under the New Revolving Credit Facility may be voluntarily prepaid at any time in whole or in part without premium or penalty, except that any prepayment of a Eurodollar loan other than the last day of the applicable interest period will be subject to customary breakage costs. In addition, at the Borrower’s option and upon three (3) business days’ prior notice, the unutilized portion of the commitments under the New Revolving Credit Facility may, subject to requirements as to minimum amounts and multiples, be permanently reduced.

Guarantee; Security

All obligations under the New Revolving Credit Facility are guaranteed by DV Midco and Ad-Juster Inc., our indirect subsidiary, and secured by a first priority perfected security interest in substantially all of the assets (subject to customary exceptions) of DV Midco, the Borrower and Ad-Juster Inc.

It is a requirement under the Credit Agreement that newly created or acquired, direct or indirect, subsidiaries of DV Midco (other than (i) a U.S. subsidiary that is a direct or indirect subsidiary of a non-U.S. subsidiary, (ii) a non-material U.S. subsidiary and (iii) a non-U.S. subsidiary) guarantee the obligations under the New Revolving Credit Facility and provide security.

Covenants, Representations and Warranties

The Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants. The negative covenants include restrictions on, among others:

● paying dividends or purchasing, redeeming or retiring capital stock;

● granting liens;

● incurring or guaranteeing additional debt;

● making investments and acquisitions;

● entering into transactions with affiliates;

● entering into any merger, consolidation or amalgamation or disposing of all or substantially all property or business; and

● disposing of property, including issuing capital stock.

The Credit Agreement also requires the Credit Group to remain in compliance with certain financial ratios.

Events of Default

The Credit Agreement includes customary events of default, including events of default relating to the nonpayment of principal or interest when due, inaccuracy of representations or warranties in any material respect, violation of covenants in the Credit Agreement or other loan documents, cross-default to other material debt, certain bankruptcy or insolvency events, certain ERISA events, certain material judgments, actual or asserted invalidity of guarantees, certain other loan documents or liens, asserted invalidity of any intercreditor or subordination agreement and a change of control, in each case subject to customary thresholds, notice and grace period provisions.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following is a discussion of material U.S. federal income tax considerations relating to the purchase, ownership and disposition of our common stock by Non-U.S. Holders (as defined below) that purchase our common stock pursuant to this offering and hold such common stock as a capital asset. This discussion is based on the Code, U.S. Treasury regulations promulgated or proposed thereunder, and administrative and judicial interpretations thereof, all as in effect on the date hereof and all of which are subject to change, possibly with retroactive effect, or to different interpretation. This discussion does not address all of the U.S. federal income tax considerations that may be relevant to specific Non-U.S. Holders in light of their particular circumstances or to Non-U.S. Holders subject to special treatment under U.S. federal income tax law (such as banks, insurance companies, dealers in securities or other Non-U.S. Holders that generally mark their securities to market for U.S. federal income tax purposes, foreign governments, international organizations, tax-exempt entities, certain former citizens or residents of the United States, foreign pension funds, “controlled foreign corporations,” “passive foreign investment companies,” partnerships or other pass-through entities for United States federal income tax purposes, or Non-U.S. Holders that hold our common stock as part of a straddle, hedge, conversion or other integrated transaction). This discussion does not address any U.S. state or local or non-U.S. tax considerations or any U.S. federal gift or alternative minimum tax considerations.

As used in this discussion, the term “Non-U.S. Holder” means a beneficial owner of our common stock (other than an entity treated as a partnership for United States federal income tax purposes) that, for U.S. federal income tax purposes, is:

● an individual who is neither a citizen nor a resident of the United States;

● a corporation (or any other entity treated as a corporation for United States federal income tax purposes) that is not created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

● an estate that is not subject to U.S. federal income tax on income from non-U.S. sources that is not effectively connected with the conduct of a trade or business in the United States; or

● a trust unless (i) a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions or (ii) it has in effect a valid election under applicable U.S. Treasury regulations to be treated as a U.S. person.

If an entity treated as a partnership for U.S. federal income tax purposes invests in our common stock, the U.S. federal income tax considerations relating to such investment will generally depend in part upon the status and activities of such entity and the particular partner. Any such entity or partner of such entity should consult its own tax advisor regarding the U.S. federal income tax considerations applicable to it and its partners relating to the purchase, ownership and disposition of our common stock.

PERSONS CONSIDERING AN INVESTMENT IN OUR COMMON STOCK SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. INCOME, ESTATE AND OTHER TAX CONSIDERATIONS RELATING TO THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES.

Distributions on Common Stock

If we make a distribution of cash or other property (other than certain pro rata distributions of our common stock or rights to acquire our common stock) with respect to a share of our common stock, the distribution generally will be treated as a dividend to the extent it is paid from our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). If the amount of such distribution exceeds our current and accumulated earnings and profits, such excess generally will be treated first as a tax-free return of capital to the extent of the Non-U.S. Holder’s adjusted tax basis in such share of our common stock, and then as capital gain (which will be treated in the manner described below under “Sale, Exchange or Other Disposition of Common Stock”). Distributions treated as dividends on our common stock that are paid to or for the account of a Non-U.S. Holder generally will be subject to U.S. federal withholding tax at a rate of 30%, or at a lower rate if provided by an applicable tax treaty. A Non-U.S. Holder that wishes to claim the benefit of an applicable treaty rate and avoid backup withholding for dividends, as discussed below, will be required (a) to provide the applicable withholding agent with a properly executed Internal Revenue Service (“IRS”) Form W-8BEN or W-8BEN-E (or other applicable form) certifying under penalty of perjury that such holder is not a U.S. person as defined under the Code and is eligible for treaty benefits or (b) if our common stock is held through certain foreign intermediaries, to satisfy the relevant

111

certification requirements of applicable United States Treasury regulations. Special certification and other requirements apply to certain Non-U.S. Holders that are pass-through entities rather than corporations or individuals. Even if our current or accumulated earnings and profits are less than the amount of the distribution, the applicable withholding agent may elect to treat the entire distribution as a dividend for U.S. federal withholding tax purposes. Each Non-U.S. Holder should consult its own tax advisor regarding U.S. federal withholding tax on distributions, including such Non-U.S. Holder’s eligibility for a lower rate and the availability of a refund of any excess U.S. federal tax withheld.

If, however, a dividend is effectively connected with the conduct of a trade or business in the United States by a Non-U.S. Holder (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment), such dividend generally will not be subject to the 30% U.S. federal withholding tax if such Non-U.S. Holder provides the appropriate documentation (generally, IRS Form W-8ECI) to the applicable withholding agent. Instead, such Non-U.S. Holder generally will be subject to U.S. federal income tax on such dividend on a net income basis in substantially the same manner as a U.S. person (except as provided by an applicable tax treaty). In addition, a Non-U.S. Holder that is treated as a corporation for U.S. federal income tax purposes may be subject to an additional branch profits tax at a rate of 30% (or a lower rate if provided by an applicable tax treaty) on its effectively connected income for the taxable year, subject to certain adjustments.

A Non-U.S. Holder eligible for a reduced rate of United States federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

The foregoing discussion is subject to the discussion below under “— FATCA Withholding” and “— Information Reporting and Backup Withholding.”

Sale, Exchange or Other Disposition of Common Stock

A Non-U.S. Holder generally will not be subject to U.S. federal income tax on any gain recognized on the sale, exchange or other disposition of our common stock unless:

(i) such gain is effectively connected with the conduct of a trade or business in the United States by such Non-U.S. Holder, in which event such Non-U.S. Holder generally will be subject to U.S. federal income tax on such gain in substantially the same manner as a U.S. person (except as provided by an applicable tax treaty) and, if it is treated as a corporation for U.S. federal income tax purposes, may also be subject to a branch profits tax at a rate of 30% (or a lower rate if provided by an applicable tax treaty), subject to certain adjustments;

(ii) such Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year of such sale, exchange or other disposition and certain other conditions are met, in which event such gain (net of certain U.S. source losses) generally will be subject to U.S. federal income tax at a rate of 30% (except as provided by an applicable tax treaty); or

(iii) we are or have been a “United States real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of (x) the five-year period ending on the date of such sale, exchange or other disposition and (y) such Non-U.S. Holder’s holding period with respect to such common stock, and certain other conditions are met.

Generally, a corporation is a “United States real property holding corporation” if the fair market value of its United States real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business (all as determined for U.S. federal income tax purposes). We believe that we presently are not, and we do not presently anticipate that we will become, a United States real property holding corporation. However, because this determination is made from time to time and is dependent upon a number of factors, some of which are beyond our control, including the value of our assets, there can be no assurance that we will not become a United States real property holding corporation. If we were a United States real property holding corporation during the period described in clause (iii) above, gain recognized by a Non-U.S. Holder generally would be treated as income effectively connected with the conduct of a trade or business in the United States by such Non-U.S. Holder, with the consequences described in clause (i) above (except that the branch profits tax would not apply), unless such Non-U.S. Holder owned (directly and constructively) five percent or less of our common stock throughout such period and our common stock is treated as “regularly traded on an established securities market” at any time during the calendar year of such sale, exchange or other disposition.

The foregoing discussion is subject to the discussion below under “FATCA Withholding” and “Information Reporting and Backup Withholding.”

FATCA Withholding

Under the Foreign Account Tax Compliance Act provisions of the Code and related U.S. Treasury guidance (“FATCA”), a withholding tax of 30% will be imposed in certain circumstances on payments of dividends on our common stock. In the case of payments made to a “foreign financial institution” (such as a bank, a broker, an investment fund or, in certain cases, a holding company), as a beneficial owner or as an intermediary, this tax generally will be imposed, subject to certain exceptions, unless such institution (i) has agreed to (and does) comply with the requirements of an agreement with the United States (an “FFI Agreement”) or (ii) is required by (and does comply with) applicable foreign law enacted in connection with an intergovernmental agreement between the United States and a foreign jurisdiction (an “IGA”) to, among other things, collect and provide to the U.S. tax authorities or other relevant tax authorities certain information regarding U.S. account holders of such institution and, in either case, such institution provides the withholding agent with a certification as to its FATCA status. In the case of payments made to a foreign entity that is not a financial institution (as a beneficial owner), the tax generally will be imposed, subject to certain exceptions, unless such entity provides the withholding agent with a certification as to its FATCA status and, in certain cases, identifies any “substantial” U.S. owner (generally, any specified U.S. person that directly or indirectly owns more than a specified percentage of such entity). If our common stock is held through a foreign financial institution that has agreed to comply with the requirements of an FFI Agreement or is subject to similar requirements under applicable foreign law enacted in connection with an IGA, such foreign financial institution (or, in certain cases, a person paying amounts to such foreign financial institution) generally will be required, subject to certain exceptions, to withhold tax on payments made to (i) a person (including an individual) that fails to provide any required information or documentation or (ii) a foreign financial institution that has not agreed to comply with the requirements of an FFI Agreement and is not subject to similar requirements under applicable foreign law enacted in connection with an IGA. If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under “— Distributions on Common Stock,” the withholding under FATCA may be credited against such other withholding tax. Each Non-U.S. Holder should consult its own tax advisor regarding these requirements and whether they may be relevant to the Non-U.S. Holder’s ownership and disposition of our common stock.

Information Reporting and Backup Withholding

Distributions on our common stock made to a Non-U.S. Holder and the amount of any U.S. federal tax withheld from such distributions generally will be reported annually to the IRS and to such Non-U.S. Holder by the applicable withholding agent. Copies of the information returns reporting such distributions and any withholding may also be made available to the tax authorities in the country in which the Non-U.S. Holder resides under the provisions of an applicable income tax treaty.

The information reporting and backup withholding rules that apply to payments of dividends to certain U.S. persons generally will not apply to payments of dividends on our common stock to a Non-U.S. Holder if such Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E to the applicable withholding agent) or otherwise establishes an exemption, and the payor does not have actual knowledge or reason to know that such holder is a U.S. person as defined under the Code.

Proceeds from the sale, exchange or other disposition of our common stock by a Non-U.S. Holder effected outside the United States through a non-U.S. office of a non-U.S. broker generally will not be subject to the information reporting and backup withholding rules that apply to payments to certain U.S. persons, provided that the proceeds are paid to the Non-U.S. Holder outside the United States. However, proceeds from the sale, exchange or other disposition of our common stock by a Non-U.S. Holder effected through a non-U.S. office of a non-U.S. broker with certain specified U.S. connections or of a U.S. broker generally will be subject to these information reporting rules (but generally not to these backup withholding rules), even if the proceeds are paid to such Non-U.S. Holder outside the United States, unless such Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E to the applicable withholding agent) or otherwise establishes an exemption. Proceeds from the sale, exchange or other disposition of our common stock by a Non-U.S. Holder effected through a U.S. office of a broker generally will be subject to these information reporting and backup withholding rules unless such Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person (generally by providing an IRS Form W-8BEN or W-8BEN-E to the applicable withholding agent) or otherwise establishes an exemption.

113

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability if the required information is furnished by such Non-U.S. Holder on a timely basis to the IRS.

U.S. Federal Estate Tax

Shares of our common stock owned or treated as owned by an individual Non-U.S. Holder at the time of such Non-U.S. Holder’s death will be included in such Non-U.S. Holder’s gross estate for U.S. federal estate tax purposes and may be subject to U.S. federal estate tax unless an applicable estate tax treaty provides otherwise.

114

UNDERWRITING

We, the selling stockholders and the underwriters named below have entered into an underwriting agreement with respect to the shares being offered hereby. Subject to certain conditions, each underwriter has severally agreed to purchase the number of shares indicated in the following table. J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC are the representatives of the underwriters.

Underwriters	Number of Shares
Goldman Sachs & Co. LLC
J.P. Morgan Securities LLC
Barclays Capital Inc.
RBC Capital Markets, LLC
Truist Securities, Inc.
Total	8,000,000

The underwriters are committed to take and pay for all of the shares being offered, if any are taken, other than the shares covered by the option described below unless and until this option is exercised.

The underwriters have an option to purchase up to an additional 1,200,000 shares from the selling stockholders to cover sales by the underwriters of a greater number of shares than the total number set forth in the table above. They may exercise that option for 30 days after the date of this prospectus. If any shares are purchased pursuant to this option, the underwriters will severally purchase shares in approximately the same proportion as set forth in the table above.

The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters by the selling stockholders. Such amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase 1,200,000 additional shares.

	No Exercise	Full Exercise
Per Share	$	$
Total	$	$

Shares sold by the underwriters to the public will initially be offered at the public offering price set forth on the cover of this prospectus. Any shares sold by the underwriters to securities dealers may be sold at a discount of up to $       per share from the public offering price. After the initial offering of the shares, the representatives may change the offering price and the other selling terms. The offering of the shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

In connection with this offering, we will agree with the underwriters, subject to certain exceptions, not to dispose of or hedge any of our common stock or securities convertible into or exchangeable for shares of common stock for a period of 90 days after the date of this prospectus, except with the prior written consent of J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC. This agreement will not apply to (i) shares of common stock to be sold in this offering, (ii) issuances of common stock by us upon the exercise of options or the settlement of restricted stock units outstanding as of the date of this prospectus or issued after the date of this prospectus pursuant to our equity plans described herein, or (iii) issuances or transfers of common stock upon the conversion or exchange of convertible or exchangeable securities outstanding as of the date of this prospectus and disclosed herein. In addition, our executive officers and directors and the selling stockholders will agree not to sell, transfer or dispose of or hedge, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for shares of our common stock for a period of 90 days after the date of this prospectus, except with the prior written consent of J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC. This agreement will be subject to certain specified exceptions, including: (i) transfers as bona fide gifts or for bona fide estate planning purposes; (ii) transfers to an immediate family member or to any trust for the benefit of the lock-up signatory or such immediate family member, or if the lock-up signatory is a trust, to a trustor or beneficiary of the trust; (iii) transfers upon death or by will, testamentary document or intestate succession; (iv) transfers (other than by certain of our officers and our directors) in connection with a sale of the lock-up signatory’s shares acquired from the underwriters in this offering or in open market transactions after the completion of this offering; (v) sales or transfers of shares of common stock in connection with the payment of tax withholdings or remittance payments due with respect to the exercise of stock options, vesting or settlement of restricted stock units or other rights to purchase shares of common stock; (vi) dispositions of shares of common stock to us, or the withholding of

115

shares of common stock by us, in connection with the payment of tax withholdings or remittance payments due with respect to the exercise of stock options, vesting or settlement of restricted stock units or other rights to purchase shares of common stock; (vii) distributions to limited partners, general partners, limited liability company members or other equityholders or to another legal entity or investment fund managed by or affiliated with such legal entity; (viii) transfers by operation of law, such as pursuant to a qualified domestic relations order or in connection with a divorce settlement; (ix) transfers to us in connection with the repurchase of common stock issued pursuant to equity awards granted under an equity incentive plan described in this prospectus or pursuant to the agreements pursuant to which such shares were issued, upon termination of the lock-up signatory’s relationship with us; (x) transfers pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction involving a change of control approved by our board of directors; (xi) pursuant to an existing written plan meeting the requirements of Rule 10b5-1 under the Exchange Act relating to the transfer, sale or other disposition of securities of the lock-up signatory; (xii) in the case of a lock-up signatory that does not sell shares of common stock in this offering, pursuant to a new written plan meeting the requirements of Rule 10b5-1 under the Exchange Act relating to the transfer, sale or other disposition of securities of the lock-up signatory; provided that such signatory may not sell shares in excess of 20% of the sum of such signatory’s aggregate amount of shares and securities convertible into or exercisable or exchangeable for common stock (on an as-converted, as-exercised or as-exchanged basis) calculated as of the date of this prospectus; (xiii) in the case of the Providence Investor, in connection with any pledge, hypothecation or other grant of a security interest in shares of common stock or securities convertible into or exchangeable for shares of common stock to one or more lending institutions as collateral or security for any loan, advance or extension of credit; provided that no transfer or sale of such shares or securities to such lending institution shall be made during the lock-up period; (xiv) if the lock-up signatory is a corporation, transfers of the capital stock of the corporation to any of its wholly-owned subsidiaries; and (xv) the establishment of a written plan meeting the requirements of Rule 10b5-1 under the Exchange Act relating to the transfer, sale or other disposition of securities of the lock-up signatory. See “Shares Available for Future Sale” for a discussion of certain transfer restrictions.

Our common stock is listed on the NYSE under the symbol “DV.”

In connection with the offering, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering, and a short position represents the amount of such sales that have not been covered by subsequent purchases. A “covered short position” is a short position that is not greater than the amount of additional shares for which the underwriters’ option described above may be exercised. The underwriters may cover any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to cover the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase additional shares pursuant to the option described above. “Naked” short sales are any short sales that create a short position greater than the amount of additional shares for which the option described above may be exercised. The underwriters must cover any such naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of common stock made by the underwriters in the open market prior to the completion of the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of our common stock, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the common stock. As a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. The underwriters are not required to engage in these activities and may end any of these activities at any time. These transactions may be effected on the NYSE, in the over-the-counter market or otherwise.

We estimate that our share of the total expenses of the offering will be approximately $950,000. The selling stockholders will bear the underwriting discounts and commissions attributable to their sale of our common stock in this offering, and we will bear the remaining expenses. We have agreed to reimburse the underwriters for certain of their expenses in an amount not to exceed $40,000.

116

We and the selling stockholders have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to us and to persons and entities with relationships with us, for which they received or will receive customary fees and reimbursement of expenses.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of the issuer (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with the issuer. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of DoubleVerify Holdings, Inc. (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations and comprehensive income, stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2020, and the related notes and the schedules listed in the Index to the consolidated financial statements (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in thousands, except per share data, unless otherwise stated)

1. Description of Business

DoubleVerify Holdings, Inc. (the “Company”) is a software platform for digital media measurement, data and analytics. The Company’s solutions provide advertisers with a single measure of digital ad quality and effectiveness, the Authentic Ad, which ensures that a digital ad was delivered in a brand-safe environment, fully viewable, by a real person and in the intended geography. The Company’s software interface, Pinnacle, provides customers with access to data on all of their digital ads and enables them to make changes to their ad strategies on a real-time basis. The Company’s software solutions are integrated across the entire digital advertising ecosystem, including programmatic platforms, social media channels and digital publishers. The Company’s solutions are accredited by the Media Rating Council, which allows the Company’s data to be used as a single-source standard in the evaluation and measurement of digital ads.

The Company was incorporated on August 16, 2017, is registered in the state of Delaware and is the parent company of DoubleVerify Midco, Inc. (“MidCo”), which is in turn the parent company of DoubleVerify Inc. (“DoubleVerify”). On August 18, 2017, DoubleVerify entered into an agreement and plan of merger (the “Agreement”), whereby the Company, formerly known as Pixel Group Holdings, Inc. (the “Ultimate Parent”) and Pixel Merger Sub, Inc. (“Merger Sub”), a wholly-owned subsidiary of the Company, agreed to provide for the merger of the Merger Sub with DoubleVerify pursuant to the terms and conditions of the Agreement.

On the effective date, Merger Sub was merged with and into DoubleVerify whereupon the separate corporate existence of Merger Sub ceased and DoubleVerify continued as the surviving corporation.

Through the merger, the Company acquired 100% of the outstanding equity instruments of DoubleVerify (the “Acquisition”) resulting in a change of control at the parent level. The merger resulted in the application of acquisition accounting under the provisions of Financial Accounting Standards Board (“FASB”) Topic Accounting Standards Codification (“ASC”) 805, “Business Combinations.”

The Company has wholly-owned subsidiaries in numerous jurisdictions including Israel, the United Kingdom, Germany, Singapore, Australia, Canada, Brazil, Belgium, Mexico, France, Japan, Spain, and Finland, and operates in one reportable segment.

Since January 2020, an outbreak of the 2019 novel coronavirus (“COVID-19”) has evolved into a worldwide pandemic. The Company has modified operations in line with business continuity plans. As a result of the pandemic, the Company has temporarily closed offices globally, including the corporate headquarters in New York, and is operating with nearly all staff working remotely. The pandemic has resulted in market disruptions and a global economic slowdown, which has materially impacted demand for a broad variety of goods and services, and is also disrupting sales channels and marketing activities. The duration of such disruptions is highly uncertain and cannot be predicted. While COVID-19 has not had a significant impact on the Company’s results from operations to date, to the extent that demand for digital advertising declines, the Company’s results and financial condition may be materially and adversely impacted.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Preparation and Principles of Consolidation

The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and reflect the financial statements of the Company and all of its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

On March 29, 2021, the Company effected a 1-for-3 reverse stock split (“reverse stock split”) of its outstanding common stock and a proportional adjustment to the existing conversion ratio for the preferred stock described in Footnote 13, Stockholders’ Equity.

F-7

Accordingly, all share and per share amounts for all periods presented in these consolidated financial statements and notes thereto, have been adjusted retrospectively, where applicable, to reflect this reverse stock split.

Use of Estimates and Judgments in the Preparation of the Consolidated Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and measurement of items including, but not limited to: revenue recognition criteria including the determination of principal versus agent revenue considerations, income taxes, the valuation and recoverability of goodwill and intangible assets, the assessment of potential loss from contingencies, assumptions in valuing acquired assets and liabilities assumed in business combinations, the allowance for doubtful accounts, and assumptions used in determining the fair value of stock-based compensation. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates. These estimates are based on the information available as of the date of the Consolidated Financial Statements.

Segment Reporting

The Company’s operating segments are determined based on the units that constitute a business for which discrete financial information is available and for which operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”). The CODM is the highest level of management responsible for assessing the Company’s overall performance and making operational decisions. The Company operates in one single operating and reportable segment.

Fair Value Measurements

The Company evaluates the fair value of certain assets and liabilities using the fair value hierarchy. Fair value is an exit price representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company applies the three-tier GAAP value hierarchy which prioritizes the inputs used in measuring fair value as follows:

Level 1 — observable inputs such as quoted prices in active markets;

Level 2 — inputs other than the quoted prices in active markets that are observable either directly or indirectly;

Level 3 — unobservable inputs of which there is little or no market data, which require the Company to develop its own assumptions.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measure.

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.

Foreign Currency

A majority of the Company’s revenues are generated in U.S. dollars. In addition, most of the Company’s costs are denominated and determined in U.S. dollars. Thus, the reporting currency of the Company is the U.S. dollar.

The functional currency of the Company’s foreign subsidiaries is generally the local currency. The assets and liabilities of subsidiaries whose functional currency is a foreign currency are translated at the period-end exchange rates. Income statement items are translated at the average monthly rates for the year. The resulting translation adjustment is recorded as a component of accumulated other comprehensive (income) loss and is included in the Consolidated Statement of Stockholders’ Equity.

F-8

For the years ended December 31, 2020, 2019, and 2018, the Company recorded an aggregate transaction loss of $0.5 million, an aggregate transaction gain of less than $0.1 million, and an aggregate transaction loss of $0.5 million, respectively. The aggregate transaction gains or losses were recorded in the Consolidated Statement of Operations and Comprehensive Income.

Cash and Cash Equivalents

The Company considers all short-term highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. Pursuant to the Company’s investment policy, its surplus funds are kept as cash or cash equivalents in money market and savings accounts to reduce its exposure to market risk.

Trade Receivables Net of Allowances for Doubtful Accounts

Trade receivables are non-interest bearing and are stated at gross invoice amounts. A receivable is recorded when the Company has an unconditional right to receive payment based on the satisfaction of performance obligations, such that only the passage of time is required before consideration is due, regardless of whether amounts are billed or unbilled. Included in trade receivables on the Consolidated Balance Sheets are unbilled receivable balances which have not yet been invoiced.

The Company estimates its allowance for doubtful accounts by evaluating specific accounts where information indicates the customers may have an inability to meet financial obligations, such as bankruptcy proceedings and receivable amounts outstanding for an extended period beyond contractual terms. In these cases, the Company uses assumptions and judgment, based on the best available facts and circumstances, to either record a specific allowance against these customer balances or to write the balances off.

Write-offs of accounts receivable are taken in the period when the Company has exhausted its efforts to collect overdue and unpaid receivables or otherwise has evaluated other circumstances that indicate that the Company should abandon such efforts.

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets on the Consolidated Balance Sheets consistent primarily of prepaid taxes, other general prepaid expenses, restricted cash, and value added tax assets. Any expenses paid prior to the related services being rendered are recorded as prepaid expenses and amortized over the period of service.

Restricted cash represents amounts pledged as collateral for certain agreements with third parties. Upon satisfying the terms of the agreements, the funds are expected to be released and available for use by the Company. As of December 31, 2020 and 2019, the Company had less than $0.1 million and $0.4 million of restricted cash, respectively.

As of December 31, 2020 and 2019, the Company had prepaid income taxes of $10.4 million and $0.9 million, respectively.

Property, Plant and Equipment, Net

Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the following estimated useful lives of the assets:

Computer equipment	3 years
Office furniture and equipment	4 ‑ 7 years
Leasehold improvements	4 ‑ 6 years

Assets under capital leases are recorded at their net present value at the inception of the lease. Assets under capital leases and leasehold improvements are amortized over the shorter of the related lease terms or their useful lives.

Expenditures which significantly improve or extend the life of an asset are capitalized, while charges for routine maintenance and repairs are expensed during the year incurred.

F-9

Capitalized Software

Capitalized software, which is included in Property, plant and equipment, net, consists of costs to purchase and develop internal-use software, which the Company uses to provide services to its customers. The costs to purchase and develop internal-use software are capitalized from the time that the preliminary project stage is completed, and it is considered probable that the software will be used to perform the function intended. These costs include personnel and related employee benefits for employees directly associated with the software development and external costs of the materials or services consumed in developing or obtaining the software. Any costs incurred during subsequent efforts to upgrade and enhance the functionality of the software are also capitalized. Once this software is ready for use in the Company’s products, these costs are amortized on a straight-line basis over the estimated useful life of the software, which is 3 years. During the years ended December 31, 2020 and December 31, 2019, the Company capitalized $5.2 million and $3.1 million in internal-use software cost, respectively. Amortization expense was $1.4 million and $0.4 million on capitalized internal-use software costs during the years ended December 31, 2020 and December 31, 2019, respectively. This is included within depreciation expense on Property, plant and equipment, net. The Company did not capitalize software costs and recognize amortization expense in 2018 as the Company did not have a process in place to track costs.

Leases

The Company leases its facilities and meets the requirements to account for these leases as operating leases. For facility leases that contain rent escalations or rent concession provisions, the Company records its lease expense during the lease term on a straight-line basis over the term of the lease. The Company records the difference between the rent paid and the straight-line rent as a deferred rent liability. Leasehold improvements funded by landlords or allowances are recorded as leasehold improvement assets and a deferred rent liability which is amortized as a reduction of rent expense over the lesser of the term of the lease or life of the asset.

The Company leases computer equipment that meet the requirements to account for these as capital leases. The Company records capital leases as an asset and an obligation at an amount equal to the present value of the minimum lease payments as determined at the beginning of the lease term. Depreciation of capitalized leased assets is computed over their useful life and is included in depreciation expense.

Business Combinations

The Company recognizes assets acquired and liabilities assumed at their fair value on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill. Acquisition-related costs are expensed as incurred.

Goodwill

Goodwill represents the excess of purchase price over the fair value of tangible net assets and identifiable intangible assets of the businesses acquired.

The valuation of goodwill involves the use of management’s estimates and assumptions. The carrying value of goodwill is not amortized, but rather, is evaluated for impairment at least annually, as of October 1, and, additionally on an interim basis, whenever events or changes in circumstances indicate that the carrying amount of goodwill will not be recoverable. The Company performs this evaluation by comparing the fair value of a reporting unit to its carrying value, including goodwill recorded by the reporting unit.

The Company has a single reporting unit. The Company’s review for impairment includes an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs a quantitative goodwill impairment test, which compares the fair value of the reporting unit with its carrying amounts. The Company estimates the fair value of its reporting unit considering both income and market-based approaches. The estimated fair value of a reporting unit is determined based on assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values.

The Company completed its analyses for each of the years ended December 31, 2020, 2019, and 2018 and determined that there was no impairment of goodwill.

Intangible Assets, Net

Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives.

The estimated useful lives of the Company’s finite-lived intangible assets are as follows:

Technology	4 ‑ 8 years
Customer relationships	5 ‑ 12 years
Trademarks	5 ‑ 15 years

Impairment of Long-Lived Assets

Long-lived assets, such as property and equipment and intangible assets subject to depreciation and amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful life is shorter than the Company had originally estimated. Recoverability of these assets is measured by comparison of the carrying amount of each asset or asset group to the future undiscounted cash flows the asset or asset group is expected to generate over their remaining lives. If the asset or asset group is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset or asset group. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the new shorter useful life. There were no impairments recognized for the years ended December 31, 2020, 2019 and 2018.

Debt Issuance Costs

Prior to the Company’s New Revolving Credit Facility, as described in Footnote 8, Long-term Debt, the Company reflected debt issuance costs for the Prior Credit Facilities in the Consolidated Balance Sheets as a direct deduction from the gross amount, consistent with the presentation of a debt discount. Debt issuance costs for the Prior Credit Facilities were amortized to interest expense over the term of the underlying debt instrument, utilizing the effective interest rate method. For the New Revolving Credit Facility, debt issuance costs meet the definition of an asset and are recorded in the Consolidated Balances Sheets in Other Non-Current Assets. Debt issuance costs incurred for the New Revolving Credit Facility that were capitalized total $0.9 million. Debt issuance costs for the New Revolving Credit Facility are amortized to interest expense over the contractual term of the underlying debt instrument on a straight-line basis through the maturity date of the instrument of October 1, 2025. As of December 31, 2020 and December 31, 2019, remaining debt issuance costs were $1.4 million and $0.9 million, respectively.

Revenue Recognition

On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (ASC 606), using the modified retrospective method. The adoption of ASU 2014-09 did not result in a material change in the timing or amount of revenue recognized. Prior to January 1, 2019, the Company recognized its revenues in accordance with ASC 605, Revenue Recognition, when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectability is probable. Results for reporting periods beginning after January 1, 2019 are presented in accordance with ASC 606, while prior period amounts have not been adjusted.

In accordance with ASC 606, the Company recognizes revenue under the core principle to depict the transfer of control to its customers in an amount reflecting the consideration to which it expected to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

The Company’s contracts with customers may include multiple promised services, consisting of the various impression measurement services the Company offers. For all revenue channels, the Company identifies performance obligations by evaluating whether the promised goods and services are capable of being distinct and distinct within the context of the contract at contract inception. Promised goods and services that are not distinct at contract inception are combined as one performance obligation. Once the Company identifies the performance obligations, the Company will determine the transaction price based on contractually fixed amounts. The Company allocates the transaction price to each performance obligation based on the standalone selling price.

F-11

The major sources of revenue include Advertiser Direct, Advertiser Programmatic, and Supply-Side Customers.

Advertiser Direct and Advertiser Programmatic Revenue

For Advertiser Direct revenue, advertisers can purchase the Company’s services to measure the quality and performance of ads purchased directly from digital properties, including publishers and social media platforms. Advertisers are provided access to the Company’s platform through the Company’s proprietary self-service software that provides the Company’s customers with access to data on all their digital ads and enables them to make changes to their ad strategies. In these arrangements, the customer pays a fee to the Company based on the ads measured.

For Advertiser Programmatic revenues, advertisers purchase the Company’s services through programmatic platforms to evaluate the quality of ad inventories before they are purchased. Advertisers may purchase the Company’s service offering through a Demand-Side Platform that manages various ad campaign auctions and inventory on behalf of the advertisers. Customers elect to use the Company’s service of evaluating the quality of advertising inventory up for bid on an advertising exchange. The ability to provide these services to customers requires that the Company enter into product integration agreements with Demand-Side Platforms who in turn make the Company’s services available to advertisers. In these arrangements, the customer pays a fee to the Company (collected by the Demand-Side Platform) for the successful execution of the purchase of advertising inventory on an exchange.

For Advertiser Direct and Advertiser Programmatic revenues, contracts with multiple performance obligations typically consist of services aimed at advertisers to help evaluate and ensure the success of a brand campaign by measuring authentic impressions. These services are generally delivered together as impressions are measured. Revenue is recognized over time, as the Company is providing services that the customer is continuously consuming and receiving benefit from or upon completion of the service. The Company considers the “right to invoice” practical expedient appropriate in the context of the Company’s contracts as this directly corresponds to the value of the Company’s performance to date. In this case, the Company’s pricing structure is (1) solely variable on the basis of the customer’s usage of the Company’s services, (2) is priced at a fixed rate per usage and (3) gives the entity the right to invoice the customer for its usage as it occurs.

Supply-Side Customers

Supply-Side Customer revenues consist of arrangements with publishers and other supply-side customers to provide them with software solutions and data analytics to enable them to maximize revenue from their digital advertising inventory. Certain arrangements include minimum guaranteed fees that reset monthly and are recognized on a straight-line basis over the access period, which is usually twelve months. For contracts that contain overages, once the minimum guaranteed amount is achieved, overages are recognized as earned over time based on a tiered pricing structure. Such revenues are recognized on an input method time-elapsed basis, as the Company is providing services that the customer is continuously consuming and receiving benefit from, and such recognition best depicts the transfer of control to the customer. Overages give rise to variable consideration that is allocated to the distinct periods to which the overage relates.

Transactions that Involve Third Parties

For transactions that involve third parties, the Company evaluates which party in the arrangement obtains control of the Company’s services (and is therefore the Company’s customer), which impacts whether the Company reports as revenue the gross amounts paid by the advertiser through the Demand-Side Platform or the net amount paid by the Company’s Demand-Side Platform partners. For certain arrangements, advertisers (“customers”) may purchase the Company’s service offering through a Demand-Side Platform that manages various ad campaign auctions and inventory on behalf of the advertisers. Customers elect to use the Company’s service of evaluating the quality of advertising inventory up for bid on an advertising exchange. The ability to provide these services to customers requires that the Company enter into product integration agreements with Demand-Side Platforms who in turn make the Company’s services available to advertisers. In these arrangements, the customer pays a fee to the Company (collected by the Demand-Side Platform) for the successful execution of the purchase of advertising inventory on an exchange. In these transactions, the Company transfers control of the Company’s services directly to the advertiser (who is the Company’s customer) and therefore revenue is recognized for the gross amount paid by the advertiser for the Company’s services. Specifically, the Company transfers control of the data that is influencing the purchasing decisions directly to the customer and the Company is primarily responsible for providing these services to the customer. That is, control of these services (or a right to these services) does not transfer to the Demand-Side Platform before they are transferred to the Company’s customers. Further, the Company has latitude in establishing the

F-12

sales price with those customers as there is a fixed retail rate card that is included in the product integration agreements with the Demand-Side Platforms or are governed by contracts in place with the customers. Accordingly, the Company records revenue for the gross amounts paid by advertisers for these services and records the amounts retained by the Demand-Side Platforms as a cost of revenue.

Contract assets relate to the Company’s conditional right to consideration for completed performance under the contract (e.g., unbilled receivables) and are included in Trade receivables, net of allowance for doubtful accounts.

Costs to Fulfill or Obtain a Contract

The Company recognizes direct fulfillment costs as an expense when incurred. These costs include commission programs to compensate employees for generating sales orders under the Company’s master services agreements or integration agreements, and are included in Sales, marketing, and customer support. The Company has not incurred incremental costs to obtain contracts during the periods ended December 31, 2020, 2019 and 2018, respectively.

Operating Expenses

Cost of revenue includes platform hosting fees, data center costs, software and other technology expenses and other costs directly associated with data infrastructure. Cost of revenue also includes personnel costs including salaries, bonuses, stock-based compensation, employee benefit costs, commissions related to revenue share arrangements with Demand-Side Platforms, and allocated overhead expenses for personnel who provide the Company’s customers with support in implementing and using the Company’s software platform. Cost of revenues excludes depreciation and amortization.

Product development expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs, and allocated overhead expenses inclusive of engineering, product and technical operation expenses, third-party consultant costs associated with the ongoing research, development and maintenance of the Company’s software platform. 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 and included in Property, plant and equipment, net on the Company’s Consolidated Balance Sheets.

Sales, marketing and customer support expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs, commission costs, and allocated overhead expenses for the Company’s sales, marketing and customer support personnel. Sales, marketing, and customer support expense also include costs for market development programs, advertising costs, attendance at events and trade shows, promotional and other marketing activities. Advertising costs include expenses associated with direct marketing but exclude the costs of attendance at events and trade shows. Advertising costs were less than $0.1 million, $0.1 million, and nil for the years ended December 31, 2020, 2019 and 2018, respectively. Commissions costs are expensed as incurred.

General and administrative expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs and other overhead expenses associated with the Company’s executive, finance, legal, human resources, compliance, and other administrative personnel, as well as accounting, tax, and legal professional services fees, rent, bad debt expense and other overhead expense related to human resource and finance activities, as well as other corporate costs including offering costs.

For the year ended December 31, 2020, the Company recorded $0.9 million in recoveries from business interruption insurance classified in General and administrative in the Consolidated Statement of Operations and Comprehensive Income. The insurance recovery related to investigating and remediating certain information technology and cybersecurity matters that occurred in the year. There were no recoveries from business interruption insurance for the years ended December 31, 2019 and 2018, respectively.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and trade receivables. The Company maintains cash deposits with financial institutions that, from time to time, exceed applicable insurance limits. The Company reduces this risk by maintaining such deposits with high quality financial institutions that management believes are creditworthy. Cash and cash equivalents are maintained with several financial institutions domestically and

F-13

internationally. The combined account balances held on deposit at each institution typically exceed Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company monitors this credit risk and makes adjustments to the concentrations as necessary. As of December 31, 2020 and 2019, the Company had deposits of $29.0 million and $7.5 million, respectively, which exceeded the FDIC insurance coverage amounts.

With respect to accounts receivable, credit risk is mitigated by the Company’s ongoing credit evaluation of its customers’ financial condition. No single customer accounted for more than 10 percent of trade receivables for the years ended December 31, 2020 and 2019. With respect to revenues, no single customer accounted for more than 10% of revenues for the years ended December 31, 2020, 2019 and 2018.

Other (Income) Expense, Net

Other (income) expense, net primarily consists of interest income, change in fair value associated with contingent considerations, loss on extinguishment of debt, and the impact of foreign currency transaction gains and losses associated with monetary assets and liabilities.

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes are provided for temporary differences in recognizing certain income, expense and credit items for financial reporting purposes and tax reporting purposes. Such deferred income taxes primarily relate to the difference between the tax bases of assets and liabilities and their financial reporting amounts. Deferred tax assets and liabilities are measured by applying enacted statutory tax rates applicable to the future years in which deferred tax assets or liabilities are expected to be settled or realized. Excess tax benefits and tax deficiencies are recognized in the income tax provision in the period in which they occur.

The Company records a valuation allowance when it determines, based on available positive and negative evidence, that it is more-likely-than-not that some portion or all of its deferred tax assets will not be realized. The Company determines the realizability of its deferred tax assets primarily based on the reversal of existing taxable temporary differences and projections of future taxable income (exclusive of reversing temporary differences and carryforwards). In evaluating such projections, the Company considers its history of profitability, the competitive environment, and general economic conditions. In addition, the Company considers the time frame over which it would take to utilize the deferred tax assets prior to their expiration.

For certain tax positions, the Company uses a more-likely-than-not threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured at the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense.

On December 22, 2017, U.S. tax reform legislation known as the Tax Cuts and Jobs Act (the “TCJA”) was signed into law. As of December 31, 2018, the Company’s accounting for the TCJA has been completed. The Company has determined the effects of certain provisions, including but not limited to: a reduction in the corporate tax rate from 35% to 21%, a limitation of the deductibility of certain officers’ compensation, a limitation on the current deductibility of net interest expense in excess of 30% of adjusted taxable income, a limitation of net operating losses generated after 2018 to 80% of taxable income, an incremental tax (base erosion anti-abuse or “BEAT”) on excessive amounts paid to foreign related parties, and a minimum tax on certain foreign earnings in excess of 10% of the foreign subsidiaries tangible assets (global intangible low- taxed income or “GILTI”). As part of its GILTI review, the Company has determined that it will account for GILTI income as it is generated (i.e., treat it as a period expense).

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (SEC Update). The update was issued to provide guidance on the income tax accounting implications of the TCJA. This includes the filing of financial statements with provisional amounts if companies are unable to finalize accounting provisions due to the changes enacted by the TCJA. In addition, subsequent changes to provisional amounts and disclosures are addressed in the ASU. The Company has completed the accounting for the effects of the Tax Act in its Consolidated Financial Statements with immaterial adjustments recorded as of December 31, 2018.

F-14

The COVID-19 pandemic has a global reach, and many countries are introducing measures that provide relief to taxpayers in a variety of ways. In March 2020, the U.S. government enacted tax legislation containing provisions to support businesses during the COVID-19 pandemic (the “CARES Act”), including deferment of the employer portion of certain payroll taxes, refundable payroll tax credits, and technical amendments to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s income tax provision for the year ended December 31, 2020.

Stock-Based Compensation

The Company accounts for stock-based compensation awards issued to its employees and members of its Board of Directors (the “Board”) in accordance with ASC 718, Compensation — Stock Compensation. ASC 718 requires that the cost resulting from all share-based payment transactions be recognized in the financial statements. This statement establishes fair value as the measurement objective in accounting for share-based payment arrangements and requires all entities to apply a fair value-based measurement method in accounting for these transactions with employees.

Stock-based compensation is measured at grant date based on the estimated fair value of the award and is expensed on a straight-line basis over the requisite service period net of an estimated forfeiture rate. The Company uses historical data to estimate forfeitures. The Company’s stock-based compensation awards relate to restricted stock units and stock options. The fair value of restricted stock unit awards is determined on the grant date based on the grant date stock price or a Monte Carlo Simulation model in instances where a market condition exists. For share-based awards that vest subject to the satisfaction of a market condition, the fair value measurement date for stock-based compensation is the date of the grant and the expense is recognized using the accelerated attribution method over the derived service period or upon achievement of the market condition. The fair value of stock option awards is determined on the grant date using the Black-Scholes Merton option pricing model. The option-pricing model requires a number of assumptions, of which the most significant are the expected stock price volatility, the expected option term and the fair market value of the Company’s common stock. Since there is no public market for the Company’s common stock, the Company bases its estimates of expected volatility on the median historical volatility of a group of publicly traded companies it believes are comparable to the Company, and uses the average of i) the weighted average vesting period and ii) the contractual life of the option, calculated using the “simplified method”. The simplified method allows for estimating the expected life based on an average of the option vesting term and option life, provided that all options meet certain criteria of “plain vanilla” options. The risk-free interest rate is based on the yield from U.S. treasury bonds as of the expected term. Additionally, the Company has assumed that dividends will not be paid.

Certain grants of stock options to executives contain certain vesting conditions, whereby, subject to the option holders continued employment with the Company, the award will vest upon the date the Company’s majority owner has received cumulative cash proceeds in respect of its investment in the Company equal to two times its aggregate cash investment in the Company. This is a market condition, but the requirement that the award vest on the basis of sufficient proceeds distributed to the Company’s majority owner represents a performance condition. During the years ended December 31, 2020, 2019 and 2018, the outcome of that performance condition is not considered probable, and therefore the Company did not recognize any expense associated with these stock options.

A certain grant of restricted stock units to an executive contains certain vesting conditions, whereby, subject to the award holders continued employment with the Company, the award will vest upon the date the Company’s achieves a certain fair market value for its common stock share price. The estimated fair value of the award was determined using a Monte Carlo Simulation model in accordance with ASC 718. During the year ended December 31, 2020, the market condition was satisfied; therefore, the Company recognized stock-based compensation expense of $0.7 million associated with these restricted stock units in General and administrative expense in the Consolidated Statements of Operations and Comprehensive Income.

Earnings Per Share

Basic and diluted earnings per share (“EPS”) are determined in accordance with ASC 260, Earnings per Share. Basic EPS is calculated by dividing net income by the weighted average number of common stock outstanding during the period. Diluted EPS is based upon the weighted average number of outstanding shares of common stock and dilutive common stock equivalents in the period. Common stock equivalents arise from dilutive stock options and restricted stock units and are computed using the treasury stock method. Anti-dilutive common stock equivalents are excluded from diluted EPS.

F-15

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with certain new or revised accounting standards. As a result, the Company’s financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

These exemptions will apply until the Company no longer meets the requirement of being an emerging growth company. The Company will remain an emerging growth company until the earlier of (a) the last day of the fiscal year (i) following the fifth anniversary of the completion of this offering, (ii) in which the Company has total annual gross revenue of at least $1.07 billion or (iii) in which the Company is deemed to be a large accelerated filer, which means the market value of the Company’s common stock that is held by non-affiliates exceeds $700.0 million as of the last business day of the Company’s prior second fiscal quarter, and (b) the date on which the Company has issued more than $1.07 billion in non-convertible debt during the prior three-year period.

Offering Costs

Offering costs consist of expenses incurred during the Company’s preparation of its proposed initial public offering (“IPO”). These expenses include registration fees, filing fees, specific legal and accounting fees which are directly related to the Company’s efforts to raise capital through an IPO. The Company expenses offering costs as they are incurred. For the year ended December 31, 2020, offering costs were $3.6 million and recorded in General and administrative in the Consolidated Statement of Operations and Comprehensive Income.

Recently Issued Accounting Pronouncements

Financial Instruments — Credit Losses

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), 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 accounts receivable. This guidance is effective for annual reporting periods beginning after December 15, 2022 for non-public entities, including interim periods within that reporting period. Early adoption is permitted. The Company is currently in process of evaluating the impact of this standard on the Company’s Consolidated Financial Statements.

Cloud Computing

In August 2018, the FASB issued ASU No. 2018-15, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2020 for non-public entities, including interim reporting periods within those annual periods. The Company is currently in process of evaluating the impact of this standard on the Company’s Consolidated Financial Statements.

Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases Topic 842 (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. ASU 2016-02 is effective for fiscal years beginning after December 15, 2021 for non-public entities, with early adoption permitted. The Company is currently in process of evaluating the impact of this standard on the Company’s Consolidated Financial Statements.

F-16

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. This guidance is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements.

Reference Rate Reform

In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU No. 2020-04”). The amendment in this update provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment in this update applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendment does not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendment in this update is effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted this amendment on March 12, 2020. There was no impact to the Consolidated Financial Statements for the year ended December 31, 2020. The Company continues to monitor the transition of LIBOR to alternative reference rate measures.

3. Revenue

The following table disaggregates revenue between advertiser customers, where revenue is generated based on number of ads measured for Direct or measured and purchased for Programmatic, and supply-side customers, where revenue is generated based on contracted minimum guarantees and tiered pricing when guarantees are met.

Disaggregated revenue by customer type is as follows:

	For the Years Ended December 31,
(in thousands)	2020		2019		2018
Advertisers — direct	$	106,422	$	84,423	$	60,122
Advertisers — programmatic		116,115		83,475		36,866
Supply‑side customer		21,380		14,765		7,316
Total Revenue	$	243,917	$	182,663	$	104,304

Contract assets relate to the Company’s conditional right to consideration for completed performance under the contract (e.g., unbilled receivables). Trade receivables, net of allowance for doubtful accounts, include unbilled receivable balances of $44.9 million and $25.1 million as of December 31, 2020 and December 31, 2019, respectively. The increase in unbilled receivable balances was driven by an increase in revenue.

For the year ended December 31, 2020, as a concession to a Demand-Side Platform partner, the Company agreed to pay $4.6 million to that partner for amounts that were incorrectly billed by the partner and remitted to the Company in the period from January 2018 through December 2019. This concession was recognized as a reduction of revenue.

4. Business Combinations

Ad-Juster, Inc.

On October 29, 2019, the Company acquired all the outstanding stock of Ad-Juster, Inc. (“Ad-Juster”), a cloud-based SaaS provider of unified data reporting and analytics solutions for digital advertising publishers. Ad-Juster products allow publishers to compile, analyze, and share data to maximize digital advertising revenue and streamline digital advertising operations across multiple platforms. Acquiring Ad-Juster creates a holistic measurement and analytics solution across the entire digital ecosystem, enhancing the Company’s current suite of products provided to Supply-Side customers. The purchase price related to this acquisition was $35.5 million in cash which included closing adjustments of approximately $0.2 million paid in February 2020. Upon acquisition, the Company used $1.8 million in cash to pay down Ad-Juster’s vested stock options, which was included in the consideration transferred. The Ad-Juster acquisition was financed with available cash drawn down from the Company’s Prior Delayed Draw Term Loan, as described in Footnote 8, Long-term Debt.

The following table summarizes the final fair value of assets acquired and liabilities assumed as of the acquisition date:

(in thousands)
Assets
Cash and cash equivalents	$	2,484

Zentrick NV

On February 15, 2019, the Company acquired all of the outstanding stock of Zentrick NV (“Zentrick”). Zentrick, headquartered in Ghent, Belgium is a digital video technology company that provides middleware solutions that increase the performance of online video advertising for brand advertisers, advertising platforms and publishers. This acquisition integrates technology into The Company’s suite of products related to advertising viewability specifically on video formats, a growing segment of the advertising market and critical for the delivery of verification services to social platform and connected TV. The aggregate purchase price consists of 1) $23.2 million paid in cash in closing, which excluded closing adjustments of approximately $0.2 million paid in April 2019 2) $0.1 million in holdback payment of which 50% was payable 12 months after the closing date, and the remaining 50% payable 24 months after the closing date 3) up to $17.3 million of performance-based deferred payments comprised of two components. The first component has a $4.0 million maximum payment related to four milestone tranches of $1.0 million each based on achievement of certain product milestones (“technical milestones”). The second component has a total maximum payment of $13.0 million and varies based upon certain revenue targets in fiscal 2019, 2020, and 2021 (“revenue targets”).

Under the terms of the deferred payment, approximately $2.4 million of the technical milestones and $5.6 million of the revenue targets is accounted for as consideration in the business combination, and approximately $1.6 million of the technical milestones and $7.4 million of the revenue targets is compensation expense under ASC 710.

As of December 31, 2020, the technical milestone and revenue target components of the contingent consideration had a fair value of $1.7 million, of which $1.2 million and $0.5 million are recorded in Contingent Considerations Current and Non-Current, respectively, in the Consolidated Balance Sheets. For the year ended December 31, 2020, the Company recorded a $0.9 million unrealized gain for the change in fair value in the Consolidated Statement of Operations and Comprehensive Income. For the year ended December 31, 2019, $1.1 million of unrealized gains were charged to the Statement of Operations and Comprehensive Income. This decrease in fair value is due to actual 2020 revenues falling below the milestone target, a decrease in forecasted 2021 revenues for the 2021 revenue target, and changes in estimates related to the timing of achievement of two of the four technical milestones by approximately 6 months.

As of December 31, 2020, the technical milestone and revenue target components treated as compensation cost total $1.1 million, of which $0.8 million and $0.3 million and are included in Other Current Liabilities and Other Non-Current Liabilities, respectively, in the Consolidated Balance Sheets. For the year ended December 31, 2020, $0.2 million were charged to and classified as Product development expense in the Consolidated Statements of Operations and Comprehensive Income respectively. For the year ended December 31, 2019, $1.7 million were charged to and classified as Product development expense in the Statement of Operations and Comprehensive Income.

Leiki Oy

On December 27, 2018, the Company acquired all of the outstanding stock of Leiki Oy (“Leiki”). Leiki is headquartered in Helsinki, Finland and provides contact and contextual classification services in multiple languages for digital text and video data to brands and publishers worldwide. This acquisition expands contextual targeting into programmatic segments and provides content classification to publishers for greater optimization. The aggregate purchase price consists of 1) $13.1 million paid in closing in cash 2) working capital adjustment to be paid within 1 year, and 3) holdback payment of approximately $4.1 million of which 50% is payable 12 months after the closing date, and the remaining 50% payable 18 months after the closing date. Upon acquisition, the Company used $0.6 million in cash to pay down Leiki’s vested stock options, which was included in the consideration transferred.

The total consideration transferred was $17.8 million. The cash consideration transferred was $13.9 million, including closing adjustments of $0.2 million that was paid in 2019. The holdback payment is not contingent on a future event occurring or condition being met but based solely on the passage of time, therefore the holdback payment is not accounted for as a contingent consideration. The holdback payment is initially measured at fair value on the acquisition date and the deferred payment is included in the total cash consideration transferred. During the year ended December 31, 2019, the company paid $2.0 million, and therefore the deferred payment balance was $2.0 million and $3.9 million as of December 31, 2019 and 2018, respectively, which is presented in liabilities in the Consolidated Balance Sheets. The remaining deferred payment of $2.0 million was fully paid during the year ended December 31, 2020.

7. Fair Value Measurement

The following tables present the Company’s financial instruments that are measured at fair value on a recurring basis:

	As of December 31, 2020
	Quoted Market
	Prices in Active				Significant
	Markets for		Significant Other		Unobservable
	Identical Assets		Observable Inputs		Inputs		Total Fair Value

Contingent consideration non‑current		—		—		1,196		1,196
Contingent consideration	$	—	$	—	$	3,210	$	3,210

Cash equivalents, consisting of money market funds and time deposits, of $2.5 million and $2.5 million as of December 31, 2020 and December 31, 2019, respectively, were classified as Level 1 of the fair value hierarchy and valued using quoted market prices in active markets.

Contingent consideration relates to potential payments that the Company may be required to make associated with a business combination. To the extent that the valuations of these liabilities are based on inputs that are less observable or not observable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for measures categorized in Level 3.

F-23

Rollforward of the fair value measurements of the contingent consideration categorized with Level 3 inputs for the years ended December 31, 2020 and December 31, 2019 is as follows:

Balance at January 1, 2019	$	—
Fair value at date of acquisition		4,689
Fair value adjustments		(1,079)
Payments during the year		(601)
Accretion expense		201
Balance at December 31, 2019	$	3,210
Fair value adjustments		(949)
Payments during the year		(601)
Balance at December 31, 2020	$	1,660

The fair value of the component of contingent consideration related to achievement of revenue targets have been estimated using a Monte Carlo model to simulate future performance of the acquired business under a risk-neutral framework; significant assumptions include a risk-adjusted discount rate of 12.7% and revenue volatility of 30.0% for December 31, 2020 and a risk-adjusted discount rate of 14.8% and revenue volatility of 23.0% for December 31, 2019. The fair value of the component of contingent consideration related to achievement of four technical milestones have been estimated using situation-based modeling, which considers the probability-weighted present value of the expected payout amount.

8. Long-term Debt

On September 20, 2017, DoubleVerify, as borrower, and Midco, as guarantor, entered into a senior secured credit facility with Capital One, National Association consisting of a $30 million term loan facility, a revolving loan facility of up to $7 million (collectively, the “Old Credit Facilities”), and a letter of credit facility of up to $3 million as a sublimit of the revolving loan facility.

On July 31, 2018, DoubleVerify, as borrower, and Midco, as guarantor, entered into an amended and restated credit agreement (the “Prior Credit Agreement”) that amended and replaced the Old Credit Facilities, providing for a $55 million term loan facility with Capital One, National Association (the “Prior Term Loan”), a $20 million delayed draw term loan facility (the “Prior Delayed Draw Term Loan”), a revolving loan facility of up to $20 million (the “Prior Revolver” and, collectively with the Prior Term Loan and the Prior Delayed Draw Term Loan, the “Prior Credit Facilities”), and a letter of credit facility of up to $5 million as a sublimit of the Prior Revolver. The Prior Credit Facilities were used to refinance the Old Credit Facilities. The Prior Credit Facilities were payable in quarterly installments of $0.1 million, had an interest rate of LIBOR plus 3.75%, and were due in full at maturity on July 31, 2023.

On October 1, 2020, DoubleVerify, as borrower, and Midco, as guarantor, entered into an amendment and restatement agreement with the banks and other financial institutions party thereto, as lenders, and Capital One, National Association, as administrative agent, letter of credit issuer and swing lender, and others, to (i) amend and restate the Prior Credit Agreement (the Prior Credit Agreement, as amended and restated on October 1, 2020, the “Credit Agreement”) and (ii) replace the Prior Credit Facilities with a new senior secured revolving credit facility (the “New Revolving Credit Facility”) in an aggregate principal amount of $150.0 million (with a letter of credit facility of up to $15.0 million as a sublimit). Subject to certain terms and conditions, the Borrower is entitled to request additional term loan facilities or increases in the revolving credit commitments under the New Revolving Credit Facility. The New Revolving Credit Facility is payable in quarterly installments for interest, with the principal balance due in full at maturity on October 1, 2025. Additional fees paid quarterly include fees for the unused revolving facility and unused letter of credit. The commitment fee on any unused balance is payable periodically and may range from 0.25% to 0.40% based upon the total net leverage ratio. The New Revolving Credit Facility bears interest at LIBOR plus 2.25%, which may vary from time to time based on DoubleVerify’s total net leverage ratio calculated in accordance with the Credit Agreement.

In connection with the amended and restated agreement, the Company recorded a loss on extinguishment of $0.4 million in Interest expense (income) in the Consolidated Statements of Operations and Comprehensive Income.

The New Revolving Credit Facility contains a number of significant negative covenants. Subject to certain exceptions, these covenants require DoubleVerify to comply with certain requirements and restrictions to, among other things: incur indebtedness; create liens; engage in mergers or consolidations; make investments, loans and advances; pay dividends or other distributions and repurchase capital stock; sell assets; engage in certain transactions with affiliates; enter into sale and leaseback transactions; and make

F-24

certain accounting changes. As a result of these restrictions, substantially all of the net assets of DoubleVerify are restricted from distribution to the Company or any of its holders of equity.

The New Revolving Credit Facility has a first priority lien on substantially all of the assets of Midco, DoubleVerify and Ad-Juster, Inc., the Company’s indirect subsidiary. The New Revolving Credit Facility requires DoubleVerify to remain in compliance with a maximum total net leverage ratio and a minimum fixed charge coverage ratio as defined in the Credit Agreement.

Maximum total net leverage ratio is measured as consolidated total net indebtedness divided by consolidated adjusted earnings before interest, taxes, depreciation and amortization for the most recently ended twelve-month period for which financial statement have been delivered, as defined by the Credit Agreement.

Minimum fixed charge coverage ratio is measured as the ratio of consolidated adjusted earnings before interest, taxes, depreciation, and amortization for the most recently ended twelve-month period for which financial statements have been delivered less the sum of consolidated capital expenditures, taxes, management fees, and restricted payments to consolidated interest expense for such period plus schedule principal payments of indebtedness, as defined by the Credit Agreement.

As of December 31, 2020, the maximum total net leverage ratio and minimum fixed charge coverage ratio is 3.5x and 1.25x, respectively. DoubleVerify is in compliance with all covenants under the New Revolving Credit Facility as of December 31, 2020.

DoubleVerify drew $90.0 million on the New Revolving Credit Facility at the close of the transaction to pay off the Prior Credit Facilities balance of $73.6 million as of September 30, 2020 and fund the repurchase of a former executive’s time-based options, as described in Footnote 12, Stock-Based Compensation for more information. On December 24, 2020, DoubleVerify paid $68.0 million of its outstanding balance under the New Revolving Credit Facility. As of December 31, 2020, $22.0 million was outstanding under the New Revolving Credit Facility due at maturity.

Non‑cash compensation	(18.7)	%	0.1	%	—	%
Effective tax rate	(18.2)	%	34.1	%	(60.4)	%

Income Tax Provision (Benefit)

The Company’s effective tax rate for the year ended December 31, 2020 was lower than the U.S. federal statutory income tax rate primarily due to the impact of non-deductible non-cash compensation, certain tax credits, foreign taxes, provision to return adjustments and the impact of other permanent book-tax differences. For the year ended December 31, 2019, the Company’s effective tax rate was higher than the U.S. federal statutory income tax rate primarily due to the impact of state and local income taxes, certain tax credits, and the impact of other permanent book-tax differences. For the year ended December 31, 2018, the Company’s effective tax rate was lower than the U.S. federal statutory income tax rate primarily due to a one-time tax benefit of return to provision adjustments related to deductible transaction costs, offset by state and local income taxes, changes in statutory rates, and other permanent book-tax differences.

Deferred Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax reporting purposes. The following table details the components of deferred tax assets and liabilities as of December 31, 2020:

	As of December 31,
(in thousands)	2020		2019
Deferred tax assets:
Allowance for doubtful accounts	$	1,819	$	1,366

Total deferred tax liabilities		(39,276)		(43,754)
Net deferred tax liabilitiy	$	(31,336)	$	(36,472)

The Company has not recorded a deferred tax liability for foreign withholding or other foreign local tax on the undistributed earnings from the Company’s international subsidiaries as such earnings are considered to be indefinitely reinvested.

F-26

Tax Valuation Allowance

The Company’s deferred tax assets and liabilities are primarily comprised of purchased intangibles, book to tax differences in depreciation and amortization, book and tax differing treatment of accruals, and net operating losses. As of each reporting date, management considers new evidence, both positive and negative, that could impact management’s view with regard to the future realization of deferred tax assets. As of December 31, 2020, (i) the Company’s taxable temporary differences will provide sufficient US future taxable income to realize the US deferred tax assets and (ii) the Company’s projected future pre-tax book income in the US and respective foreign countries is expected to provide sufficient taxable income to realize the deferred tax assets within each jurisdiction’s respective statutory carryforward period. Based on this analysis, the Company has concluded that it is more likely than not that the Company will realize most of its US and foreign deferred taxes assets. A valuation allowance is assessed to a small amount of foreign capital losses and US tax loss carryforwards.

Net Operating Loss and Credit Carryforwards

As of December 31, 2020, the Company had a Federal net operating loss carryforward of approximately $0.3 million and a state net operating loss carryforward of approximately $10.9 million. In addition, the Company had loss carryforwards for various foreign countries where the Company has business operations. The aggregate amount of foreign loss carryover is not material as of December 31, 2020. Federal net operating loss carryforwards can be used to offset against taxable income in the future and begin to expire in 2031. The Company utilized approximately $3.0 million and $2.7 million of Federal and state net operating loss carryforwards, respectively, in 2020. Utilization of Federal net operating loss carryforwards may be subject to annual limitations due to the “change in ownership” provisions of the Internal Revenue Code of 1986 and similar state provisions. The Company’s net operating loss carryforwards are subject to the annual limitation under Section 382 of the Internal Revenue Code.

Uncertain Tax Positions

The Company’s income tax returns are open to examination by federal and state authorities for the tax years ended December 31, 2016 and later. However, the Company believes that its tax positions are all highly certain of being upheld upon examination and intends to defend those positions if challenged by the Internal Revenue Services or another taxing jurisdiction.

For uncertain tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. The Company has unrecognized tax benefits, which are tax benefits related to uncertain tax positions which have been or will be reflected in income tax filings that have not been recognized in the financial statements due to potential adjustments by taxing authorities in the applicable jurisdictions. The Company’s liabilities for unrecognized tax benefits, which include interest and penalties, were $1.9 million and $0.6 million as of December 31, 2020 and 2019, respectively. The amount of unrecognized tax benefits that, if recognized, would affect the Company’s effective tax rate are $1.8 million and $0.5 million as of December 31, 2020 and 2019, respectively and include the federal tax benefit of state deductions. The Company anticipates that no unrecognized tax benefits will reverse during the next year due to the expiration of statutes of limitation.

Changes in the Company’s unrecognized tax benefits are as follows:

	For the Years

Upon the closing of the sale of shares of common stock in an underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933, all outstanding shares of preferred stock shall automatically be converted into shares of common stock on a 1:1 basis, subject to anti-dilution protection included in terms of the preferred stock and the reverse stock split whereby each share of preferred stock is entitled to convert into one third of one share of common stock. In general, the anti-dilution protection requires a modification to the conversion price upon conversion to common stock to the extent additional shares are issued that are not considered to be part of the category of exempted securities, as defined by the Preferred Purchase Agreement, and at no consideration or consideration per share less than the conversion price in effect immediately prior to such event. Exempted securities include, but are not limited to, common stock or options issued to employees, directors, contractors, or consultants pursuant to the Company’s equity plan.

Proceeds from the issuance were used to pay off a portion of the outstanding balance under the New Revolving Credit Facility.

1.    Description of Business

DoubleVerify is a software platform for digital media measurement, data and analytics. The Company’s solutions provide advertisers with a single measure of digital ad quality and effectiveness, the DV Authentic Ad, which ensures that a digital ad was delivered in a brand-safe environment, fully viewable, by a real person and in the intended geography. The Company’s software interface, DV Pinnacle, provides customers with access to data on all of their digital ads and enables them to make changes to their ad strategies on a real-time basis. The Company’s software solutions are integrated across the entire digital advertising ecosystem, including programmatic platforms, Connected TV (“CTV”), social media channels and digital publishers. The Company’s solutions are accredited by the Media Rating Council, which allows the Company’s data to be used as a single-source standard in the evaluation and measurement of digital ads.

The Company was incorporated on August 16, 2017, is registered in the state of Delaware and is the parent company of DoubleVerify Midco, Inc. (“MidCo”), which is in turn the parent company of DoubleVerify Inc. On August 18, 2017, DoubleVerify Inc. entered into an agreement and plan of merger (the “Agreement”), whereby the Company, formerly known as Pixel Group Holdings, Inc. and Pixel Merger Sub, Inc. (“Merger Sub”), a wholly owned subsidiary of the Company, agreed to provide for the merger of the Merger Sub with DoubleVerify Inc. pursuant to the terms and conditions of the Agreement.

On the effective date, Merger Sub was merged with and into DoubleVerify Inc. whereupon the separate corporate existence of Merger Sub ceased and DoubleVerify Inc. continued as the surviving corporation.

Through the merger, the Company acquired 100% of the outstanding equity instruments of DoubleVerify Inc. resulting in a change of control at the parent level. The merger resulted in the application of acquisition accounting under the provisions of Financial Accounting Standards Board (“FASB”) Topic Accounting Standards Codification (“ASC”) 805, Business Combinations.

The Company has wholly owned subsidiaries in numerous jurisdictions including Israel, the United Kingdom, Germany, Singapore, Australia, Canada, Brazil, Belgium, Mexico, France, Japan, Spain, and Finland, and operates in one reportable segment.

On April 23, 2021, the Company completed an initial public offering of its common stock (“IPO”). See Footnote 12, Stockholders’ Equity.

2.     Basis of Presentation and Summary of Significant Accounting Policies

Basis of Preparation and Principles of Consolidation

The accompanying Condensed Consolidated Balance Sheets as of September 30, 2021 and December 31, 2020, the Condensed Consolidated Statements of Operations and Comprehensive Income for the three and nine months ended September 30, 2021 and 2020, the Condensed Consolidated Statements of Stockholders’ Equity for the three and nine months ended September 30, 2021 and 2020, and the Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2021 and 2020 reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair presentation of the results for the periods shown in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the applicable rules and regulations of the SEC for interim financial reporting periods. Accordingly, certain information and footnote disclosures have been condensed or omitted pursuant to SEC rules that would ordinarily be required under GAAP for complete financial statements. These unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements as of December 31, 2020 and 2019 and for the years then ended and the accompanying notes thereto included in the Company’s Prospectus.

On March 29, 2021, the Company effected a 1-for-3 reverse stock split (‘‘reverse stock split’’) of its outstanding common stock, par value $0.001 per share (“common stock”), and a proportional adjustment to the existing conversion ratio of its then-outstanding Series A Preferred Stock, par value $0.01 per share (“preferred stock”). Accordingly, all share and per share amounts for all periods presented in these Condensed Consolidated Financial Statements and notes thereto, have been adjusted retrospectively, where applicable, to reflect this reverse stock split.

Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and measurement of items including, but not limited to: revenue recognition criteria including the determination of principal versus agent revenue considerations, income taxes, the valuation and recoverability of goodwill and intangible assets, the assessment of potential loss from contingencies, the allowance for doubtful accounts, and assumptions used in determining the fair value of stock-based compensation. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. These estimates are based on the information available as of the date of the Condensed Consolidated Financial Statements.

Recently Issued Accounting Pronouncements

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with certain new or revised accounting standards.

Financial Instruments - Credit Losses

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), 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 accounts receivable. This guidance is effective for annual reporting periods beginning after December 15, 2022 for non-public entities, including interim periods within that reporting period. Early adoption is permitted and the update allows for a modified retrospective method of adoption. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Cloud Computing

In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2020 for non-public entities, and interim periods within annual periods beginning after December 15, 2021. The update allows for a retrospective or prospective method of adoption.

The Company intends to adopt amendment ASU No. 2018-15 on December 31, 2021 using a prospective approach. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases Topic 842 (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. In July 2018, FASB issued ASU No. 2018- 10, Codification Improvements to Topic 842, Leases, ("ASU No. 2018-10") to further clarify,

F-45

DoubleVerify Holdings, Inc.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Amounts in thousands, except per share data, unless otherwise stated)

correct and consolidate various areas previously discussed in ASU 2016-02. FASB also issued ASU No. 2018- 11, Leases: Targeted Improvements ("ASU 2018-11") to provide entities another option for transition and lessors with a practical expedient. The transition option allows entities to not apply ASU No. 2016-02 in comparative periods in the financial statements in the year of adoption. The amendments in ASU No. 2016-02, ASU No. 2018-10 and ASU No. 2018-11 are effective for fiscal years beginning after December 15, 2021 for non-public entities and interim periods within fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. For non-public entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. Certain amendments included in the update allows for a retrospective, modified retrospective, or prospective method of adoption. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

3.     Revenue

The following table disaggregates revenue between advertiser customers, where revenue is generated based on number of ads measured for Direct or measured and purchased for Programmatic, and supply-side customers, where revenue is generated based on contracts with minimum guarantees or contracts that contain overages after minimum guarantees are achieved.

Disaggregated revenue by customer type is as follows:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
(in thousands)	2021		2020		2021		2020
Advertiser - direct	$	34,057	$	27,582	$	93,260	$	73,476
Advertiser - programmatic		41,902		28,044		113,694		76,023
Supply-side customer		7,139		5,411		20,254		15,777
Total revenue	$	83,098	$	61,037	$	227,208	$	165,276

Contract assets relate to the Company’s conditional right to consideration for completed performance under the contract (e.g., unbilled receivables). Trade receivables, net of allowance for doubtful accounts, include unbilled receivable balances of $36.1 million and $44.9 million as of September 30, 2021 and December 31, 2020, respectively.

4.    Business Combinations

Meetrics GmbH

On August 31, 2021, the Company acquired all of the outstanding stock of Meetrics GmbH (“Meetrics”). Meetrics was founded in 2008 in Berlin, Germany and is a European-based ad verification provider – offering comprehensive media quality measurement solutions across viewability, fraud, brand safety and suitability. The aggregate net cash purchase price was $24.3 million. This

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Amounts in thousands, except per share data, unless otherwise stated)

acquisition expands DoubleVerify’s international presence as substantially all of Meetrics’ customer base and business operations are based in Europe, the Middle East, and Africa.

The following table summarizes the preliminary fair value of assets acquired and liabilities assumed as of the acquisition date:

(in thousands)	Acquisition Date
Assets:
Cash and cash equivalents	$	1,007
Trade receivables		948
Other assets		96
Property, plant and equipment		27
Intangible assets:
Technology		2,245
Customer relationships		7,208
Trademarks		47
Non-compete agreements		71
Total intangible assets		9,571
Goodwill		17,057
Total assets acquired	$	28,706
Liabilities:
Trade payables	$	145
Other current liabilities		345
Deferred tax liability		2,886
Total liabilities assumed		3,376
Total purchase consideration	$	25,330
Cash acquired		(1,007)
Net cash purchase price		24,323

The acquired intangible assets of Meetrics will be amortized over their estimated useful lives. Accordingly, customer relationships will be amortized over fourteen years, developed technology will be amortized over four years, non-compete agreements will be amortized over two years, and trademarks will be amortized over one year. The total weighted-average useful life of the acquired intangible assets as of September 30, 2021 is 11.4 years. The Company recognized a deferred tax liability of $2.9 million in relation to the intangible assets acquired.

The goodwill and identified intangible assets are not deductible for tax purposes. The Company incurred acquisition-related transaction costs of $0.7 million included in General and Administrative expenses in the Condensed Consolidated Statement of Operations and Comprehensive Income for the three and nine months ended September 30, 2021.

The goodwill associated with Meetrics includes the acquired assembled work force, the value associated with the opportunity to leverage the work force to continue to develop the future generations of verification technology assets, as well as the ability to grow the Company through adding additional customer relationships or new solutions in the future.

The preliminary allocations of the purchase price for Meetrics are subject to revisions as additional information is obtained about the facts and circumstances that existed as of the acquisition date. The revisions may have a significant impact on the accompanying condensed consolidated financial statements. The allocations of the purchase price will be finalized once all information is obtained and assessed, not to exceed one year from the acquisition date.

Zentrick NV

On February 15, 2019, the Company acquired all of the outstanding stock of Zentrick NV (“Zentrick”). Zentrick, headquartered in Ghent, Belgium is a digital video technology company that provides middleware solutions that increase the performance of online video advertising for brand advertisers, advertising platforms and publishers. This acquisition integrates technology into the Company’s suite of products related to advertising viewability specifically on video formats, a growing segment of the advertising market and critical for the delivery of verification services to social platforms and CTV. The aggregate purchase price consists of 1) $23.2 million paid in cash at closing, which excluded closing adjustments of approximately $0.2 million paid in April 2019 2) $0.1 million in holdback payment of which 50% was payable 12 months after the closing date, and the remaining 50% was payable 24 months after the closing date and 3) up to $17.3 million of performance-based deferred payments that comprises two components (the “Zentrick Deferred Payment Terms”). The first component has a $4.0 million maximum payment related to four milestone tranches of $1.0 million each based on achievement of certain product milestones (“technical milestones”). The second component has a total maximum payment of $13.0 million and varies based upon certain revenue targets in fiscal 2019, 2020, and 2021 (“revenue targets”).

As of September 30, 2021, the technical milestone and revenue target components of the contingent consideration had a fair value of $1.2 million and $0.5 million, respectively, and is recorded in Contingent Considerations Current in the Condensed Consolidated Balance Sheets. There was no change in fair value in the Condensed Consolidated Statement of Operations and Comprehensive Income for the three months ended September 30, 2021. For the nine months ended September 30, 2021, the Company recorded a $0.1 million unrealized loss for the change in fair value in the Condensed Consolidated Statement of Operations and Comprehensive Income. The Company recorded less than $0.1 million unrealized gain and $0.9 million unrealized gain for the change in fair value in the Condensed Consolidated Statement of Operations and Comprehensive Income for the three and nine months ended September 30, 2020, respectively.

As of September 30, 2021, the technical milestone and revenue target components treated as compensation cost total $1.1 million and is included in Other Current Liabilities in the Condensed Consolidated Balance Sheets. For the three months ended September 30, 2021, there were no charges to the Condensed Consolidated Statements of Operations and Comprehensive Income. For the nine months ended September 30, 2021, less than $0.1 million was charged to the Condensed Consolidated Statements of Operations and Comprehensive Income.

Cash equivalents consisting of money market funds of $11.7 million and money market funds and time deposits of $2.5 million as of September 30, 2021 and December 31, 2020, respectively, were classified as Level 1 of the fair value hierarchy and valued using quoted market prices in active markets.

Contingent consideration relates to potential payments that the Company may be required to make associated with a business combination. To the extent that the valuations of these liabilities are based on inputs that are less observable or not observable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for measures categorized in Level 3.

The fair value of the component of contingent consideration related to achievement of revenue targets have been estimated using a Monte Carlo model to simulate future performance of the acquired business under a risk-neutral framework; significant assumptions include a risk-adjusted discount rate of 13.5% and revenue volatility of 29.0%. The fair value of the component of contingent consideration related to achievement of four technical milestones have been estimated using situation-based modeling, which considers the probability-weighted present value of the expected payout amount.

8.     Long-term Debt

On October 1, 2020, DoubleVerify Inc., as borrower (the “Borrower”), and MidCo, as guarantor, entered into an amendment and restatement agreement with the banks and other financial institutions party thereto, as lenders, and Capital One, National Association, as administrative agent, letter of credit issuer and swing lender, and others, to (i) amend and restate the Prior Credit Agreement as defined in the Prospectus (the Prior Credit Agreement, as amended and restated on October 1, 2020, the “Credit Agreement”) and (ii) replace the Prior Credit Facilities (as defined in the Prospectus) with a new senior secured revolving credit facility (the “New Revolving Credit Facility”) in an aggregate principal amount of $150.0 million (with a letter of credit facility of up to $15.0 million as a sublimit). Subject to certain terms and conditions, the Borrower is entitled to request additional term loan facilities or increases in the revolving credit commitments under the New Revolving Credit Facility. The New Revolving Credit Facility is payable in quarterly installments for interest, with the principal balance due in full at maturity on October 1, 2025. Additional fees paid quarterly include fees for the unused revolving facility and unused letter of credit. The commitment fee on any unused balance is payable periodically and may range from 0.25% to 0.40% based upon the total net leverage ratio. The New Revolving Credit Facility bears interest at LIBOR plus 2.25%, which may vary from time to time based on the Borrower’s total net leverage ratio calculated in accordance with the Credit Agreement.

The New Revolving Credit Facility contains a number of significant negative covenants. Subject to certain exceptions, these covenants require the Borrower to comply with certain requirements and restrictions to, among other things: incur indebtedness; create liens; engage in mergers or consolidations; make investments, loans and advances; pay dividends or other distributions and repurchase capital stock; sell assets; engage in certain transactions with affiliates; enter into sale and leaseback transactions; and make certain accounting changes. As a result of these restrictions, substantially all of the net assets of the Borrower are restricted from distribution to the Company or any of its holders of equity.

The New Revolving Credit Facility has a first priority lien on substantially all of the assets of MidCo, the Borrower and Ad-Juster, Inc., the Company’s indirect subsidiary. The New Revolving Credit Facility requires the Borrower to remain in compliance with a maximum total net leverage ratio and a minimum fixed charge coverage ratio as defined in the Credit Agreement.

As of September 30, 2021, the maximum total net leverage ratio and minimum fixed charge coverage ratio is 3.5x and 1.25x, respectively. The Borrower is in compliance with all covenants under the New Revolving Credit Facility as of September 30, 2021.

On April 30, 2021 the Company used a portion of the proceeds from the IPO and the concurrent private placement to pay the outstanding balance. As of September 30, 2021 and December 31, 2020, there was $0 outstanding and $22.0 million outstanding under the New Revolving Credit Facility, respectively.

9.     Income Tax

The Company’s quarterly income tax provision is calculated using an estimated annual effective income tax rate ("ETR") based on actual historical information and forward-looking estimates. The Company’s estimated annual ETR may fluctuate due to changes in forecasted annual pre-tax income, changes in the jurisdictional mix of forecasted pre-tax income, and changes to actual or forecasted permanent book to tax differences (e.g., non-deductible expenses). In addition, the Company’s ETR for a particular reporting period may fluctuate as the result of changes to the valuation allowance for net deferred tax assets, the impact of anticipated tax settlements with federal, state, or foreign tax authorities, or the impact of tax law changes. The Company identifies items that are unusual and non-recurring in nature and treat these as discrete events. The tax effect of these discrete events is booked entirely in the quarter in which they occur.

During the three and nine months ended September 30, 2021, the Company recorded an income tax provision of $3.3 million and $8.4 million, respectively, resulting in an effective tax rate of 29.2% and 89.3%, which includes an annualized effective tax provision of $3.3 million and $2.7 million (representing an effective tax rate of 29.2% and 29.1%) and discrete items relating primarily to transaction costs and state tax refunds of $0 and $5.6 million (representing an effective tax rate of 0.0% and 60.2%), respectively. During the three and nine months ended September 30, 2020, the Company recorded an income tax benefit of $1.4 million and an income tax provision of $2.0 million, respectively, resulting in an effective tax rate of (31.1%) and 13.8%, respectively. These effective tax rates differ from the U.S. federal statutory rate primarily due to the effects of differing treatment of transaction costs between book and tax, foreign tax rate differences, U.S. tax on foreign operations, and U.S. state/local taxes.

The COVID-19 (as defined herein) pandemic has a global reach, and many countries are introducing measures that provide relief to taxpayers in a variety of ways. In March 2020, the U.S. government enacted tax legislation containing provisions to support businesses during the COVID-19 pandemic (the “CARES Act”), including deferment of the employer portion of certain payroll taxes, refundable payroll tax credits, and technical amendments to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s income tax provision for the three and nine months ended September 30, 2021.

A valuation allowance has been established against a non-material amount of certain net foreign deferred tax assets and US tax loss carryforward. All other net deferred tax assets have been determined to be more likely than not realizable.

The Company and its subsidiaries file income tax returns with the Internal Revenue Service (“IRS”) and various state and international jurisdictions. The Company’s Israeli subsidiary is under audit by the Israeli Tax Authority for the 2016-2018 tax years. This examination may lead to ordinary course adjustments or proposed adjustments to the Company’s taxes. Aside from this, the Company is not currently under audit in any other jurisdiction.

On August 31, 2021, the Company acquired all of the outstanding stock of Meetrics, a German corporation, in a sale treated as a non-taxable event at the corporate level. The Company has calculated a preliminary tax basis balance sheet and deferred tax impact of the acquisition. The Company has recorded a deferred tax liability of $2.9 million relating to varying tax and book basis differences of intangible assets and goodwill.

In addition, Meetrics maintains net operating loss carryforwards of approximately $5.0 million through December 31, 2020. Based on a preliminary review of all positive and negative evidence, it appears to not be more likely than not that Meetrics will be able to utilize these loss carryforwards. Therefore, a deferred tax asset of $1.5 million has been recorded, which is fully offset by a valuation allowance.

Approximately 4.6 million, and 4.3 million weighted average shares issuable under stock-based awards were not included in the diluted EPS calculation in the three and nine months ended September 30, 2021, respectively, because they were antidilutive. Approximately 9.2 million, and 7.5 million weighted average shares issuable under stock-based awards were not included in the diluted EPS calculation in the three and nine months ended September 30, 2020, respectively, because they were also antidilutive.

11.   Stock-Based Compensation

Employee Equity Incentive Plan

On September 20, 2017, the Company established its 2017 Omnibus Equity Incentive Program (the “2017 Plan”) which provides for the granting of equity based awards to certain employees, directors, independent contractors, consultants and agents. Under the 2017 Plan, the Company may grant non-qualified stock options, stock appreciation rights, restricted stock units, and other stock-based awards for up to 22,182 shares of common stock.

On April 19, 2021 the Company established its 2021 Omnibus Equity Incentive Plan (“2021 Equity Plan”). The maximum number of shares of common stock available for issuance under the 2021 Equity Plan is equal to the sum of (i) 30,000 shares of common stock and (ii) an annual increase on the first day of each year beginning in 2022 and ending in and including 2031, equal to the lesser of (A) five percent (5%) of the outstanding shares of common stock on the last day of the immediately preceding fiscal year and (B) such lesser amount as determined by the Board’s compensation committee. The 2021 Equity Plan provides for the grant of stock options (including qualified incentive stock options and nonqualified stock options), stock appreciation rights, restricted stock, restricted stock units, dividend equivalents, and other stock or cash settled incentive awards. Any shares covered by an award, or portion of an award, granted under the 2021 Equity Plan that expires or is forfeited, canceled, cash-settled, or otherwise terminated for any reason will again be available for the grant of awards under the 2021 Equity Plan.

Options become exercisable subject to vesting schedules up to four years from the date of the grant and subject to certain timing restrictions upon an employee’s separation of service and no later than 10 years after the grant date.

Restricted stock units are subject to vesting schedules up to four years from the date of the grant and subject to certain timing restrictions upon an employee’s separation.

Employee Stock Purchase Plan

In March 2021, the Board approved the Company’s 2021 Employee Stock Purchase Plan (“ESPP”), and employees became eligible to enroll in August 2021. The ESPP qualifies as an “employee stock purchase plan” under Section 423 of the U.S. Internal Revenue Code of 1986, as amended.

The Company reserved 3,000 shares of common stock for sale under the ESPP. The share reserve increases on the first day of each calendar year beginning on January 1, 2022 and ending on and including January 1, 2031, equal to the lesser of (i) one percent (1%) of the aggregate number of shares of common stock outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares of common stock as is determined by the Board.

Purchases are accomplished through participation in discrete offering periods. Currently, the ESPP is available only to U.S. based employees; the Company is reviewing offering the ESPP program to employees in non-U.S. jurisdictions. The first offering and purchase period began on September 1, 2021 and will end on November 30, 2021. The Company expects the program to continue consecutively for six-month offering periods (commencing on December 1, 2021) for the foreseeable future.

Under the ESPP, eligible employees are able to acquire shares of the Company’s common stock by accumulating funds through payroll deductions. Company employees in the United States generally are eligible to participate in the ESPP if they are a full-time employee and have completed six months of continuous service with the Company as of the last day of the enrollment period. Eligible employees are able to select a rate of payroll deduction between 1% and 15% of their compensation, up to a $25 annual contribution limit. The purchase price for shares of common stock purchased under the ESPP is 85% of the lesser of the fair market value of the common stock on (i) the first trading day of the applicable offering period and (ii) the last trading day of the applicable offering period. An employee’s participation automatically ends upon termination of employment for any reason. A participant may cancel enrollment or lower their contributions once during an offering period, but no later than 30 days before the end of an offering period. Upon the termination of an employee’s participation in the ESPP, payroll deductions will be stopped and refunded.

Stock-based compensation expense for the ESPP is recognized on a straight-line basis over the requisite service period of each award. The ESPP also has a six-month holding period after the purchase date of the offering period. Stock-based compensation expense related to ESPP totaled less than $0.1 million for the three and nine months ended September 30, 2021.

12. Stockholders’ Equity

The Company received aggregate net proceeds of $253.2 million from the IPO, after deducting underwriting discount fees of $16.2 million. The Company incurred offering costs of approximately $26.8 million for the concurrent private placement and IPO, of which $0 and $21.8 million were included in General and Administrative expenses in the Condensed Consolidated Statement of Operations and Comprehensive Income for the three and nine months ended September 30, 2021, respectively. The IPO offering also included 5,356 shares sold by Providence VII U.S. Holdings L.P. (“Providence”) and other existing stockholders, which included the full exercise of the underwriters’ option to purchase 650 additional shares from Providence, in which the Company did not receive any proceeds from the shares sold.

In connection with the Company’s IPO, all shares of the Company’s outstanding preferred stock automatically converted into 20,335 shares of common stock on a one for one-third basis. The Company’s treasury stock, consisting of 15,146 shares of common stock, was reissued in the preferred stock conversion.

In conjunction with the IPO, the Company increased the authorized shares of its capital stock. The Company’s capital stock consists of 1,000,000 shares of common stock, par value $0.001 per share and 100,000 shares of undesignated preferred stock, par value $0.01 per share. Further, the Company amended and restated its existing amended and restated certificate of incorporation and its existing bylaws of the Company, as previously reported in the Prospectus, which incorporates material modifications to rights of security holders.

Contingencies

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. The Company records liabilities for contingencies including legal costs when it is probable that a liability has been incurred and when the amount can be reasonably estimated. Legal costs are expensed as incurred. 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 effect on the Company’s business, financial condition, results of operations or cash flows.

DoubleVerify Holdings, Inc.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Amounts in thousands, except per share data, unless otherwise stated)

With respect to potential payments due related to the Zentrick acquisition, discussed in Footnote 4, Business Combinations, the Company and the Zentrick selling stockholders are currently in discussions to negotiate the early termination of the Zentrick Deferred Payment Terms and resolution of the contingent payments due for both the technical milestones and revenue targets. The Company believes the total of approximately $2.8 million for these potential payments reflected in the Condensed Consolidated Balance Sheet as contingent consideration current and other current liabilities reflect the Company’s estimated obligations under the stock purchase agreement entered into in connection with the transaction, as of September 30, 2021. In efforts to terminate early the Zentrick Deferred Payment Terms, the Company believes payment between $2.8 million and $5.5 million is possible, with no amount within the range being a better estimate than the amount recorded on the Condensed Consolidated Balance Sheets.

14.    Segment Information

The Company has determined that it operates as one operating and reportable segment. The Company’s chief operating decision maker reviews financial information on a consolidated basis, together with certain operating and performance measures principally to make decisions about how to allocate resources and measure performance.

The Company has not disclosed certain geographic information pertaining to revenues and total assets as it is impracticable to disclose, is not utilized by the Company’s chief operating decision maker to review operating results or make decisions about how to allocate resources, and would not be useful to users of the Condensed Consolidated Financial Statements to disclose such information.

Item 14.Indemnification of Directors and Officers.

Delaware Law

DoubleVerify Holdings, Inc. (the “Registrant”) is incorporated under the laws of the State of Delaware.

Section 145(a) of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful.

Section 145(b) of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper.

Section 145(c) of the DGCL provides that to the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of Section 145 of the DGCL, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith.

Section 145(e) of the DGCL provides that expenses (including attorneys’ fees) incurred by an officer or director of the corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in Section 145 of the DGCL. Such expenses, including attorneys’ fees, incurred by former directors and officers or other employees and agents of the corporation or by persons serving at the request of the corporation as directors, officers, employees or

II-1

agents of another corporation, partnership, joint venture, trust or other enterprise may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.

Section 145(g) of the DGCL specifically allows a Delaware corporation to purchase liability insurance on behalf of its directors and officers and to insure against potential liability of such directors and officers regardless of whether the corporation would have the power to indemnify such directors and officers under Section 145 of the DGCL.

Section 102(b)(7) of the DGCL permits a Delaware corporation to include a provision in its certificate of incorporation eliminating or limiting the personal liability of directors to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. This provision, however, may not eliminate or limit a director’s liability (1) for breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or involving intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL, which provides for liability of directors for unlawful payments of dividends or unlawful stock purchases, redemptions or other distributions, or (4) for any transaction from which the director derived an improper personal benefit.

Section 174 of the DGCL provides, among other things, that a director who willfully and negligently approves of an unlawful payment of dividends or an unlawful stock purchase or redemption may be held liable for such actions. A director who was either absent when the unlawful actions were approved or dissented at the time may avoid liability by causing his or her dissent to such actions to be entered in the books containing the minutes of the meetings of the board of directors at the time the action occurred or immediately after the absent director receives notice of the unlawful acts.

Our amended and restated certificate of incorporation contains provisions permitted under the DGCL relating to the liability of directors. These provisions eliminate a director’s personal liability for monetary damages resulting from a breach of fiduciary duty, except in circumstances involving:

●any breach of the director’s duty of loyalty;

●acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law;

●unlawful payments of dividends or unlawful stock purchases, redemptions or other distributions; or

●any transaction from which the director derives an improper personal benefit.

If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. Any repeal or modification of these provisions in our amended and restated certificate of incorporation shall not adversely affect any right or protection of a director existing at the time of such repeal or modification.

Our amended and restated certificate of incorporation and our amended and restated bylaws require us to indemnify and advance expenses to our directors and officers to the fullest extent not prohibited by the DGCL and other applicable law, except in the case of a proceeding instituted by the director without the approval of our Board. Our amended and restated certificate of incorporation and our amended and restated bylaws provide that we are required to indemnify our directors and officers, to the fullest extent permitted by law, for all judgments, fines, settlements, legal fees and other expenses incurred in connection with pending or threatened legal proceedings because of the director’s or officer’s positions with us or another entity that the director or officer serves at our request, subject to various conditions, and to advance funds to our directors and officers to enable them to defend against such proceedings. To receive indemnification, the director or officer must have been successful in the legal proceeding or have acted in good faith and in what was reasonably believed to be a lawful manner in our best interest and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. No repeal or modification of any of these provisions in our amended and restated bylaws or any relevant provisions of the DGCL shall adversely affect any right or obligation of a director or officer existing at the time of such repeal or modification with respect to any state of facts then or previously existing or any proceeding previously or thereafter brought or threatened based in whole or in part upon any such state of facts.

Indemnification Agreements

We have entered into an indemnification agreement with each of our directors. The indemnification agreements provide our directors with contractual rights to the indemnification and expense advancement rights provided under our amended and restated bylaws, as well as contractual rights to additional indemnification as provided in the indemnification agreements.

II-2

Directors’ and Officers’ Liability Insurance

We have directors’ and officers’ liability insurance which insures against certain liabilities that our directors and officers and the directors and officers of our subsidiaries may, in such capacities, incur.

Item 15.Recent Sales of Unregistered Securities.

The offers, sales and issuances of the securities described above were deemed to be exempt from registration under the Securities Act, including in reliance upon Rule 701 promulgated under Section 3(b) of the Securities Act or Rule 506 promulgated under Section 4(a)(2) of the Securities Act. None of the foregoing transactions involved any underwriters, underwriting discounts or commissions or any public offering. Each of the recipients of securities in these transactions had adequate access, through employment, business or other relationships, to information about us.

Item 17.Undertakings.

(a) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(b)The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

9.(a)  The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any “roadshow” as defined in Rule 433(h) under the Act (a “roadshow”) or any "issuer information" filed or required to be filed pursuant to Rule 433(d) under the Act (“Issuer Information”), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any roadshow, in reliance upon and in conformity with any Underwriter Information.

(b)Each of the Selling Stockholders, severally and not jointly, will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any roadshow or any Issuer Information, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any roadshow or any Issuer Information, in reliance upon and in conformity with any Selling Stockholder Information relating to such Selling Stockholder; and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that such Selling Stockholder shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any roadshow or any Issuer Information, in reliance upon and in conformity with any Underwriter Information.

(c) Each Underwriter, severally and not jointly, will indemnify and hold harmless (i) the Company, its directors, each officer who signed the Registration Statement and each person, if any,

23

who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and (ii) each Selling Stockholder and each person, if any, who controls such Selling Stockholder within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company or such Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any roadshow or any Issuer Information, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, any roadshow or any Issuer Information, in reliance upon and in conformity with any Underwriter Information; and will reimburse the Company and each Selling Stockholder for any legal or other expenses reasonably incurred by the Company or such Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred.  As used in this Agreement with respect to an Underwriter and an applicable document, “Underwriter Information” shall mean the written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the name of each Underwriter, the concession figure appearing in the fifth paragraph under the caption “Underwriting”, and the information contained in the eighth, ninth, thirteenth and fourteenth paragraphs under the caption “Underwriting”.

(d)Promptly after receipt by an indemnified party under subsection (a), (b), or (c) of this Section9 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; provided that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 9 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under the preceding paragraphs of this Section 9.  In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the

24

indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them.  No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(e)If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b), or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other from the offering of the Shares and with the proportion among the Company and the Selling Stockholders to reflect the relative fault of the Company and the Selling Stockholders.  If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholders on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations and with the proportion among the Company and the Selling Stockholders to reflect the relative fault of the Company and the Selling Stockholders.  The relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Selling Stockholders bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus.  The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Stockholders on the one hand or the Underwriters on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Company, each of the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation (even if the Selling Stockholders or the Underwriters, as applicable, were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any documented legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares

25

underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no Selling Stockholder shall be required to contribute any amount in excess of the amount by which the net proceeds after commissions but before offering expenses received by such Selling Stockholder from the sale of the Shares under this Agreement exceeds any damages which such Selling Stockholder has otherwise been required to pay by reason of an untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Underwriters' obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint.

(f)The obligations of the Company and the Selling Stockholders under this Section 9 shall be in addition to any liability which the Company and the Selling Stockholders may otherwise have and shall extend, upon the same terms and conditions, to each employee, officer and director of each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer or other affiliate of any Underwriter; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and to each person, if any, who controls the Company or any Selling Stockholder within the meaning of the Act.

10.(a)If any Underwriter shall default in its obligation to purchase the Shares that it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein.  If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Company and the Selling Stockholders shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Shares on such terms.  In the event that, within the respective prescribed periods, you notify the Company and the Selling Stockholders that you have so arranged for the purchase of such Shares, or the Company or a Selling Stockholder notifies you that it has so arranged for the purchase of such Shares, you or the Company or the Selling Stockholders shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary.  The term "Underwriter" as used in this Agreement shall include any person substituted under this Section 10 with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b)If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Selling Stockholders shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such

26

defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c)If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all of the Shares to be purchased at such Time of Delivery, or if the Selling Stockholders shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to a Second Time of Delivery, the obligations of the Underwriters to purchase and of Providence to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders, except for the expenses to be borne by the Company, the Selling Stockholders and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11.The respective indemnities, rights of contribution, agreements, representations, warranties and other statements of the Company, the Selling Stockholders and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any director, officer, employee, affiliate or controlling person of any Underwriter, or the Company, or any of the Selling Stockholders, or any officer or director or controlling person of the Company, or any controlling person of any Selling Stockholder, and shall survive delivery of and payment for the Shares.

12.If this Agreement shall be terminated pursuant to Section 10 hereof, neither the Company nor the Selling Stockholders shall then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason any Shares are not delivered by or on behalf of the Selling Stockholders as provided herein, or the Underwriters decline to purchase the Shares for any reason permitted under this Agreement, each of the Selling Stockholders pro rata (based on the number of Shares to be sold by such Selling Stockholder hereunder) will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including documented fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company and the Selling Stockholders shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

13.In all dealings hereunder, the Representatives shall act jointly on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representatives jointly; and in all dealings with any Selling Stockholder hereunder, you and the Company shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of such Selling Stockholder made or given by any or all of the Attorneys-in-Fact for such Selling Stockholder.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company and the Selling Stockholders, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

Re:  DoubleVerify Holdings, Inc. - Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that J.P. Morgan Securities LLC and Goldman Sachs & Co. LLC, as representatives (the “Representatives”), propose to enter into an underwriting agreement (the “Underwriting Agreement”) on behalf of the several Underwriters named in Schedule I thereto (collectively, the “Underwriters”), with DoubleVerify Holdings, Inc., a Delaware corporation (the “Company”) and the stockholders of the Company named in Schedule II to the Underwriting Agreement, providing for a public offering (the “Offering”) of shares of common stock, par value $0.001 per share, of the Company (“Common Stock,” and such shares, the “Shares”) pursuant to a Registration Statement on Form S-1 to be filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of this lock-up agreement (this “Lock-Up Agreement”) and continuing to and including the date 90 days after the date (the “Offering Date”) set forth on the final prospectus (the “Prospectus”) used to sell the Shares (the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, (i) offer, sell, contract to sell, pledge, grant any option to purchase, lend or otherwise dispose of any shares of Common Stock of the Company, or any options or warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock of the Company (such options, warrants or other securities, collectively, “Derivative Instruments”), including without

limitation any such shares or Derivative Instruments now owned or hereafter acquired by the undersigned, (ii) engage in any hedging or other transaction or arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) which is designed to or which reasonably could be expected to lead to or result in a sale, loan, pledge or other disposition (whether by the undersigned or someone other than the undersigned), or transfer of any of the economic consequences of ownership, in whole or in part, directly or indirectly, of any shares of Common Stock of the Company or Derivative Instruments, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Common Stock or other securities, in cash or otherwise (any such sale, loan, pledge or other disposition, or transfer of economic consequences, a “Transfer”) or (iii) otherwise publicly announce any intention to engage in or cause any action or activity described in clause (i) above or transaction or arrangement described in clause (ii) above. The undersigned represents and warrants that the undersigned is not, and has not caused or directed any of its affiliates to be or become, currently a party to any agreement or arrangement that provides for, is designed to or which reasonably could be expected to lead to or result in any Transfer during the Lock-Up Period. For the avoidance of doubt, if the undersigned is an officer (as defined under the rules and regulations of the Financial Industry Regulatory Authority, Inc. (“FINRA”)) or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed or other Shares the undersigned may purchase in the Offering.

If the undersigned is not a natural person, the undersigned represents and warrants that no single natural person, entity or “group” (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), other than a natural person, entity or “group” (as described above) that has executed a lock-up agreement in substantially the same form as this Lock-Up Agreement, beneficially owns, directly or indirectly, 50% or more of the common equity interests, or 50% or more of the voting power, in the undersigned.

(2)to any person related to the undersigned by blood, marriage, domestic partnership or adoption, not more remote than first cousin (any such person, an “immediate family member”) or to any trust for the direct or indirect benefit of the undersigned or an immediate family member of the undersigned, or if the undersigned is a trust, to a trustor or beneficiary of the trust (including such beneficiary’s estate) of the undersigned; provided that the transferee agrees to be bound in writing by the restrictions set forth herein; provided further that any such transfer shall not involve a disposition for value; and provided further that no filing under Section 16(a) of the Exchange Act reporting such transfer of the undersigned’s shares of Common Stock shall be required or shall be voluntarily made during the Lock-Up Period (other than any required Form 5 filing after the end of the calendar year in which such transaction occurs);

Registration Statement on Form S-1of

DoubleVerify Holdings, Inc.

Ladies and Gentlemen:

We have acted as special New York counsel to DoubleVerify Holdings, Inc., a Delaware corporation (the “Company”), in connection with the filing with the U.S. Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), of a Registration Statement on Form S-1 (the “Registration Statement”) relating to a public offering (the “Offering”) of 8,000,000 shares of the Company’s Common Stock, par value $0.001 per share (the “Common Stock”), to be sold by Providence VII U.S. Holdings L.P. (“Providence”) and the other selling stockholders (collectively with Providence, the “Selling Stockholders”) referred to in the Registration Statement (such shares of Common Stock, together with up to 1,200,000 shares of Common Stock that may be sold upon exercise of the underwriters’ option to purchase additional shares of Common Stock and any additional shares of Common Stock that may be registered in accordance with Rule 462(b) under the Act for sale in the Offering, the “Shares”) pursuant to an underwriting agreement (the “Underwriting Agreement”) to be entered into among the Company, the Selling Stockholders and the several underwriters to be named in Schedule I thereto (the “Underwriters”).

In arriving at the opinion expressed below, we have (a) examined and relied on the originals, or copies certified or otherwise identified to our satisfaction, of such agreements, corporate or other organizational documents and records of the Company and such certificates of public officials, officers and representatives of the Company and other persons as we have deemed appropriate for the purposes of such opinion, (b) examined and relied as to factual matters upon, and have assumed the accuracy of, the statements made in the certificates of public officials, officers and representatives of the Company and others delivered to us and (c) made such investigations of law as we have deemed appropriate as a basis for such opinion. In rendering the opinion expressed below, we have assumed, with your permission,

DoubleVerify Holdings, Inc. 2 November 15, 2021

without independent investigation or inquiry, (i) the authenticity and completeness of all documents that we examined, (ii) the genuineness of all signatures on all documents that we examined, (iii) the conformity to authentic originals and completeness of documents examined by us that are certified, conformed, reproduction, photostatic or other copies, (iv) the legal capacity of all natural persons executing documents and (v) that the Pricing Committee of the board of directors of the Company will have taken action necessary to set the sale price of the Shares.

Based upon and subject to the foregoing and the assumptions, qualifications and limitations hereinafter set forth, we are of the opinion that the Shares to be sold to the Underwriters by the Selling Stockholders pursuant to the Underwriting Agreement have been duly authorized and are validly issued, fully paid and non-assessable under the laws of the State of Delaware.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement, to the reference to our firm under the caption “Validity of Common Stock” in the prospectus forming a part thereof and to the incorporation by reference of this opinion and consent as exhibits to any registration statement filed in accordance with Rule 462(b) under the Act relating to the Offering. In giving such consent, we do not concede that we are within the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.

We are members of the bar of the State of New York. We express no opinion as to the laws of any jurisdiction other than the General Corporation Law of the State of Delaware, as currently in effect.

The merger resulted in the application of acquisition accounting under the provisions of Financial Accounting Standards Board (“FASB”) Topic Accounting Standards Codification (“ASC”) 805, “Business Combinations.”

The Company has wholly-owned subsidiaries in numerous jurisdictions including Israel, the United Kingdom, Germany, Singapore, Australia, Canada, Brazil, Belgium, Mexico, France, Japan, Spain, and Finland, and operates in one reportable segment.

Since January 2020, an outbreak of the 2019 novel coronavirus (“COVID-19”) has evolved into a worldwide pandemic. The Company has modified operations in line with business continuity plans. As a result of the pandemic, the Company has temporarily closed offices globally, including the corporate headquarters in New York, and is operating with nearly all staff working remotely. The pandemic has resulted in market disruptions and a global economic slowdown, which has materially impacted demand for a broad variety of goods and services, and is also disrupting sales channels and marketing activities. The duration of such disruptions is highly uncertain and cannot be predicted. While COVID-19 has not had a significant impact on the Company’s results from operations to date, to the extent that demand for digital advertising declines, the Company’s results and financial condition may be materially and adversely impacted.

Basis of Preparation and Principles of Consolidation

The accompanying Condensed Consolidated Balance Sheets as of September 30, 2021 and December 31, 2020, the Condensed Consolidated Statements of Operations and Comprehensive Income for the three and nine months ended September 30, 2021 and 2020, the Condensed Consolidated Statements of Stockholders’ Equity for the three and nine months ended September 30, 2021 and 2020, and the Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2021 and 2020 reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair presentation of the results for the periods shown in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the applicable rules and regulations of the SEC for interim financial reporting periods. Accordingly, certain information and footnote disclosures have been condensed or omitted pursuant to SEC rules that would ordinarily be required under GAAP for complete financial statements. These unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements as of December 31, 2020 and 2019 and for the years then ended and the accompanying notes thereto included in the Company’s Prospectus.

On March 29, 2021, the Company effected a 1-for-3 reverse stock split (‘‘reverse stock split’’) of its outstanding common stock, par value $0.001 per share (“common stock”), and a proportional adjustment to the existing conversion ratio of its then-outstanding Series A Preferred Stock, par value $0.01 per share (“preferred stock”). Accordingly, all share and per share amounts for all periods presented in these Condensed Consolidated Financial Statements and notes thereto, have been adjusted retrospectively, where applicable, to reflect this reverse stock split.

Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and measurement of items including, but not limited to: revenue recognition criteria including the determination of principal versus agent revenue considerations, income taxes, the valuation and recoverability of goodwill and intangible assets, the assessment of potential loss from contingencies, the allowance for doubtful accounts, and assumptions used in determining the fair value of stock-based compensation. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. These estimates are based on the information available as of the date of the Condensed Consolidated Financial Statements.

Recently Issued Accounting Pronouncements

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with certain new or revised accounting standards.

Financial Instruments - Credit Losses

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), 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 accounts receivable. This guidance is effective for annual reporting periods beginning after December 15, 2022 for non-public entities, including interim periods within that reporting period. Early adoption is permitted and the update allows for a modified retrospective method of adoption. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Cloud Computing

In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2020 for non-public entities, and interim periods within annual periods beginning after December 15, 2021. The update allows for a retrospective or prospective method of adoption.

The Company intends to adopt amendment ASU No. 2018-15 on December 31, 2021 using a prospective approach. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases Topic 842 (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. In July 2018, FASB issued ASU No. 2018- 10, Codification Improvements to Topic 842, Leases, ("ASU No. 2018-10") to further clarify,

correct and consolidate various areas previously discussed in ASU 2016-02. FASB also issued ASU No. 2018- 11, Leases: Targeted Improvements ("ASU 2018-11") to provide entities another option for transition and lessors with a practical expedient. The transition option allows entities to not apply ASU No. 2016-02 in comparative periods in the financial statements in the year of adoption. The amendments in ASU No. 2016-02, ASU No. 2018-10 and ASU No. 2018-11 are effective for fiscal years beginning after December 15, 2021 for non-public entities and interim periods within fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. For non-public entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. Certain amendments included in the update allows for a retrospective, modified retrospective, or prospective method of adoption. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Preparation and Principles of Consolidation

The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and reflect the financial statements of the Company and all of its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

On March 29, 2021, the Company effected a 1-for-3 reverse stock split (“reverse stock split”) of its outstanding common stock and a proportional adjustment to the existing conversion ratio for the preferred stock described in Footnote 13, Stockholders’ Equity.

Accordingly, all share and per share amounts for all periods presented in these consolidated financial statements and notes thereto, have been adjusted retrospectively, where applicable, to reflect this reverse stock split.

Use of Estimates and Judgments in the Preparation of the Consolidated Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and measurement of items including, but not limited to: revenue recognition criteria including the determination of principal versus agent revenue considerations, income taxes, the valuation and recoverability of goodwill and intangible assets, the assessment of potential loss from contingencies, assumptions in valuing acquired assets and liabilities assumed in business combinations, the allowance for doubtful accounts, and assumptions used in determining the fair value of stock-based compensation. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates. These estimates are based on the information available as of the date of the Consolidated Financial Statements.

Segment Reporting

The Company’s operating segments are determined based on the units that constitute a business for which discrete financial information is available and for which operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”). The CODM is the highest level of management responsible for assessing the Company’s overall performance and making operational decisions. The Company operates in one single operating and reportable segment.

Fair Value Measurements

The Company evaluates the fair value of certain assets and liabilities using the fair value hierarchy. Fair value is an exit price representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company applies the three-tier GAAP value hierarchy which prioritizes the inputs used in measuring fair value as follows:

Level 1 — observable inputs such as quoted prices in active markets;

Level 2 — inputs other than the quoted prices in active markets that are observable either directly or indirectly;

Level 3 — unobservable inputs of which there is little or no market data, which require the Company to develop its own assumptions.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measure.

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.

Foreign Currency

A majority of the Company’s revenues are generated in U.S. dollars. In addition, most of the Company’s costs are denominated and determined in U.S. dollars. Thus, the reporting currency of the Company is the U.S. dollar.

The functional currency of the Company’s foreign subsidiaries is generally the local currency. The assets and liabilities of subsidiaries whose functional currency is a foreign currency are translated at the period-end exchange rates. Income statement items are translated at the average monthly rates for the year. The resulting translation adjustment is recorded as a component of accumulated other comprehensive (income) loss and is included in the Consolidated Statement of Stockholders’ Equity.

For the years ended December 31, 2020, 2019, and 2018, the Company recorded an aggregate transaction loss of $0.5 million, an aggregate transaction gain of less than $0.1 million, and an aggregate transaction loss of $0.5 million, respectively. The aggregate transaction gains or losses were recorded in the Consolidated Statement of Operations and Comprehensive Income.

Cash and Cash Equivalents

The Company considers all short-term highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. Pursuant to the Company’s investment policy, its surplus funds are kept as cash or cash equivalents in money market and savings accounts to reduce its exposure to market risk.

Trade Receivables Net of Allowances for Doubtful Accounts

Trade receivables are non-interest bearing and are stated at gross invoice amounts. A receivable is recorded when the Company has an unconditional right to receive payment based on the satisfaction of performance obligations, such that only the passage of time is required before consideration is due, regardless of whether amounts are billed or unbilled. Included in trade receivables on the Consolidated Balance Sheets are unbilled receivable balances which have not yet been invoiced.

The Company estimates its allowance for doubtful accounts by evaluating specific accounts where information indicates the customers may have an inability to meet financial obligations, such as bankruptcy proceedings and receivable amounts outstanding for an extended period beyond contractual terms. In these cases, the Company uses assumptions and judgment, based on the best available facts and circumstances, to either record a specific allowance against these customer balances or to write the balances off.

Write-offs of accounts receivable are taken in the period when the Company has exhausted its efforts to collect overdue and unpaid receivables or otherwise has evaluated other circumstances that indicate that the Company should abandon such efforts.

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets on the Consolidated Balance Sheets consistent primarily of prepaid taxes, other general prepaid expenses, restricted cash, and value added tax assets. Any expenses paid prior to the related services being rendered are recorded as prepaid expenses and amortized over the period of service.

Restricted cash represents amounts pledged as collateral for certain agreements with third parties. Upon satisfying the terms of the agreements, the funds are expected to be released and available for use by the Company. As of December 31, 2020 and 2019, the Company had less than $0.1 million and $0.4 million of restricted cash, respectively.

As of December 31, 2020 and 2019, the Company had prepaid income taxes of $10.4 million and $0.9 million, respectively.

Property, Plant and Equipment, Net

Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the following estimated useful lives of the assets:

Computer equipment	3 years
Office furniture and equipment	4 ‑ 7 years
Leasehold improvements	4 ‑ 6 years

Assets under capital leases are recorded at their net present value at the inception of the lease. Assets under capital leases and leasehold improvements are amortized over the shorter of the related lease terms or their useful lives.

Expenditures which significantly improve or extend the life of an asset are capitalized, while charges for routine maintenance and repairs are expensed during the year incurred.

Capitalized Software

Capitalized software, which is included in Property, plant and equipment, net, consists of costs to purchase and develop internal-use software, which the Company uses to provide services to its customers. The costs to purchase and develop internal-use software are capitalized from the time that the preliminary project stage is completed, and it is considered probable that the software will be used to perform the function intended. These costs include personnel and related employee benefits for employees directly associated with the software development and external costs of the materials or services consumed in developing or obtaining the software. Any costs incurred during subsequent efforts to upgrade and enhance the functionality of the software are also capitalized. Once this software is ready for use in the Company’s products, these costs are amortized on a straight-line basis over the estimated useful life of the software, which is 3 years. During the years ended December 31, 2020 and December 31, 2019, the Company capitalized $5.2 million and $3.1 million in internal-use software cost, respectively. Amortization expense was $1.4 million and $0.4 million on capitalized internal-use software costs during the years ended December 31, 2020 and December 31, 2019, respectively. This is included within depreciation expense on Property, plant and equipment, net. The Company did not capitalize software costs and recognize amortization expense in 2018 as the Company did not have a process in place to track costs.

Leases

The Company leases its facilities and meets the requirements to account for these leases as operating leases. For facility leases that contain rent escalations or rent concession provisions, the Company records its lease expense during the lease term on a straight-line basis over the term of the lease. The Company records the difference between the rent paid and the straight-line rent as a deferred rent liability. Leasehold improvements funded by landlords or allowances are recorded as leasehold improvement assets and a deferred rent liability which is amortized as a reduction of rent expense over the lesser of the term of the lease or life of the asset.

The Company leases computer equipment that meet the requirements to account for these as capital leases. The Company records capital leases as an asset and an obligation at an amount equal to the present value of the minimum lease payments as determined at the beginning of the lease term. Depreciation of capitalized leased assets is computed over their useful life and is included in depreciation expense.

Business Combinations

The Company recognizes assets acquired and liabilities assumed at their fair value on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill. Acquisition-related costs are expensed as incurred.

Goodwill

Goodwill represents the excess of purchase price over the fair value of tangible net assets and identifiable intangible assets of the businesses acquired.

The valuation of goodwill involves the use of management’s estimates and assumptions. The carrying value of goodwill is not amortized, but rather, is evaluated for impairment at least annually, as of October 1, and, additionally on an interim basis, whenever events or changes in circumstances indicate that the carrying amount of goodwill will not be recoverable. The Company performs this evaluation by comparing the fair value of a reporting unit to its carrying value, including goodwill recorded by the reporting unit.

The Company has a single reporting unit. The Company’s review for impairment includes an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs a quantitative goodwill impairment test, which compares the fair value of the reporting unit with its carrying amounts. The Company estimates the fair value of its reporting unit considering both income and market-based approaches. The estimated fair value of a reporting unit is determined based on assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values.

The Company completed its analyses for each of the years ended December 31, 2020, 2019, and 2018 and determined that there was no impairment of goodwill.

Intangible Assets, Net

Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives.

The estimated useful lives of the Company’s finite-lived intangible assets are as follows:

Technology	4 ‑ 8 years
Customer relationships	5 ‑ 12 years
Trademarks	5 ‑ 15 years

Impairment of Long-Lived Assets

Long-lived assets, such as property and equipment and intangible assets subject to depreciation and amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful life is shorter than the Company had originally estimated. Recoverability of these assets is measured by comparison of the carrying amount of each asset or asset group to the future undiscounted cash flows the asset or asset group is expected to generate over their remaining lives. If the asset or asset group is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset or asset group. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the new shorter useful life. There were no impairments recognized for the years ended December 31, 2020, 2019 and 2018.

Debt Issuance Costs

Prior to the Company’s New Revolving Credit Facility, as described in Footnote 8, Long-term Debt, the Company reflected debt issuance costs for the Prior Credit Facilities in the Consolidated Balance Sheets as a direct deduction from the gross amount, consistent with the presentation of a debt discount. Debt issuance costs for the Prior Credit Facilities were amortized to interest expense over the term of the underlying debt instrument, utilizing the effective interest rate method. For the New Revolving Credit Facility, debt issuance costs meet the definition of an asset and are recorded in the Consolidated Balances Sheets in Other Non-Current Assets. Debt issuance costs incurred for the New Revolving Credit Facility that were capitalized total $0.9 million. Debt issuance costs for the New Revolving Credit Facility are amortized to interest expense over the contractual term of the underlying debt instrument on a straight-line basis through the maturity date of the instrument of October 1, 2025. As of December 31, 2020 and December 31, 2019, remaining debt issuance costs were $1.4 million and $0.9 million, respectively.

Revenue Recognition

On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (ASC 606), using the modified retrospective method. The adoption of ASU 2014-09 did not result in a material change in the timing or amount of revenue recognized. Prior to January 1, 2019, the Company recognized its revenues in accordance with ASC 605, Revenue Recognition, when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectability is probable. Results for reporting periods beginning after January 1, 2019 are presented in accordance with ASC 606, while prior period amounts have not been adjusted.

In accordance with ASC 606, the Company recognizes revenue under the core principle to depict the transfer of control to its customers in an amount reflecting the consideration to which it expected to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

The Company’s contracts with customers may include multiple promised services, consisting of the various impression measurement services the Company offers. For all revenue channels, the Company identifies performance obligations by evaluating whether the promised goods and services are capable of being distinct and distinct within the context of the contract at contract inception. Promised goods and services that are not distinct at contract inception are combined as one performance obligation. Once the Company identifies the performance obligations, the Company will determine the transaction price based on contractually fixed amounts. The Company allocates the transaction price to each performance obligation based on the standalone selling price.

The major sources of revenue include Advertiser Direct, Advertiser Programmatic, and Supply-Side Customers.

Advertiser Direct and Advertiser Programmatic Revenue

For Advertiser Direct revenue, advertisers can purchase the Company’s services to measure the quality and performance of ads purchased directly from digital properties, including publishers and social media platforms. Advertisers are provided access to the Company’s platform through the Company’s proprietary self-service software that provides the Company’s customers with access to data on all their digital ads and enables them to make changes to their ad strategies. In these arrangements, the customer pays a fee to the Company based on the ads measured.

For Advertiser Programmatic revenues, advertisers purchase the Company’s services through programmatic platforms to evaluate the quality of ad inventories before they are purchased. Advertisers may purchase the Company’s service offering through a Demand-Side Platform that manages various ad campaign auctions and inventory on behalf of the advertisers. Customers elect to use the Company’s service of evaluating the quality of advertising inventory up for bid on an advertising exchange. The ability to provide these services to customers requires that the Company enter into product integration agreements with Demand-Side Platforms who in turn make the Company’s services available to advertisers. In these arrangements, the customer pays a fee to the Company (collected by the Demand-Side Platform) for the successful execution of the purchase of advertising inventory on an exchange.

For Advertiser Direct and Advertiser Programmatic revenues, contracts with multiple performance obligations typically consist of services aimed at advertisers to help evaluate and ensure the success of a brand campaign by measuring authentic impressions. These services are generally delivered together as impressions are measured. Revenue is recognized over time, as the Company is providing services that the customer is continuously consuming and receiving benefit from or upon completion of the service. The Company considers the “right to invoice” practical expedient appropriate in the context of the Company’s contracts as this directly corresponds to the value of the Company’s performance to date. In this case, the Company’s pricing structure is (1) solely variable on the basis of the customer’s usage of the Company’s services, (2) is priced at a fixed rate per usage and (3) gives the entity the right to invoice the customer for its usage as it occurs.

Supply-Side Customers

Supply-Side Customer revenues consist of arrangements with publishers and other supply-side customers to provide them with software solutions and data analytics to enable them to maximize revenue from their digital advertising inventory. Certain arrangements include minimum guaranteed fees that reset monthly and are recognized on a straight-line basis over the access period, which is usually twelve months. For contracts that contain overages, once the minimum guaranteed amount is achieved, overages are recognized as earned over time based on a tiered pricing structure. Such revenues are recognized on an input method time-elapsed basis, as the Company is providing services that the customer is continuously consuming and receiving benefit from, and such recognition best depicts the transfer of control to the customer. Overages give rise to variable consideration that is allocated to the distinct periods to which the overage relates.

Transactions that Involve Third Parties

For transactions that involve third parties, the Company evaluates which party in the arrangement obtains control of the Company’s services (and is therefore the Company’s customer), which impacts whether the Company reports as revenue the gross amounts paid by the advertiser through the Demand-Side Platform or the net amount paid by the Company’s Demand-Side Platform partners. For certain arrangements, advertisers (“customers”) may purchase the Company’s service offering through a Demand-Side Platform that manages various ad campaign auctions and inventory on behalf of the advertisers. Customers elect to use the Company’s service of evaluating the quality of advertising inventory up for bid on an advertising exchange. The ability to provide these services to customers requires that the Company enter into product integration agreements with Demand-Side Platforms who in turn make the Company’s services available to advertisers. In these arrangements, the customer pays a fee to the Company (collected by the Demand-Side Platform) for the successful execution of the purchase of advertising inventory on an exchange. In these transactions, the Company transfers control of the Company’s services directly to the advertiser (who is the Company’s customer) and therefore revenue is recognized for the gross amount paid by the advertiser for the Company’s services. Specifically, the Company transfers control of the data that is influencing the purchasing decisions directly to the customer and the Company is primarily responsible for providing these services to the customer. That is, control of these services (or a right to these services) does not transfer to the Demand-Side Platform before they are transferred to the Company’s customers. Further, the Company has latitude in establishing the

sales price with those customers as there is a fixed retail rate card that is included in the product integration agreements with the Demand-Side Platforms or are governed by contracts in place with the customers. Accordingly, the Company records revenue for the gross amounts paid by advertisers for these services and records the amounts retained by the Demand-Side Platforms as a cost of revenue.

Contract assets relate to the Company’s conditional right to consideration for completed performance under the contract (e.g., unbilled receivables) and are included in Trade receivables, net of allowance for doubtful accounts.

Costs to Fulfill or Obtain a Contract

The Company recognizes direct fulfillment costs as an expense when incurred. These costs include commission programs to compensate employees for generating sales orders under the Company’s master services agreements or integration agreements, and are included in Sales, marketing, and customer support. The Company has not incurred incremental costs to obtain contracts during the periods ended December 31, 2020, 2019 and 2018, respectively.

Operating Expenses

Cost of revenue includes platform hosting fees, data center costs, software and other technology expenses and other costs directly associated with data infrastructure. Cost of revenue also includes personnel costs including salaries, bonuses, stock-based compensation, employee benefit costs, commissions related to revenue share arrangements with Demand-Side Platforms, and allocated overhead expenses for personnel who provide the Company’s customers with support in implementing and using the Company’s software platform. Cost of revenues excludes depreciation and amortization.

Product development expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs, and allocated overhead expenses inclusive of engineering, product and technical operation expenses, third-party consultant costs associated with the ongoing research, development and maintenance of the Company’s software platform. 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 and included in Property, plant and equipment, net on the Company’s Consolidated Balance Sheets.

Sales, marketing and customer support expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs, commission costs, and allocated overhead expenses for the Company’s sales, marketing and customer support personnel. Sales, marketing, and customer support expense also include costs for market development programs, advertising costs, attendance at events and trade shows, promotional and other marketing activities. Advertising costs include expenses associated with direct marketing but exclude the costs of attendance at events and trade shows. Advertising costs were less than $0.1 million, $0.1 million, and nil for the years ended December 31, 2020, 2019 and 2018, respectively. Commissions costs are expensed as incurred.

General and administrative expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs and other overhead expenses associated with the Company’s executive, finance, legal, human resources, compliance, and other administrative personnel, as well as accounting, tax, and legal professional services fees, rent, bad debt expense and other overhead expense related to human resource and finance activities, as well as other corporate costs including offering costs.

For the year ended December 31, 2020, the Company recorded $0.9 million in recoveries from business interruption insurance classified in General and administrative in the Consolidated Statement of Operations and Comprehensive Income. The insurance recovery related to investigating and remediating certain information technology and cybersecurity matters that occurred in the year. There were no recoveries from business interruption insurance for the years ended December 31, 2019 and 2018, respectively.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and trade receivables. The Company maintains cash deposits with financial institutions that, from time to time, exceed applicable insurance limits. The Company reduces this risk by maintaining such deposits with high quality financial institutions that management believes are creditworthy. Cash and cash equivalents are maintained with several financial institutions domestically and

internationally. The combined account balances held on deposit at each institution typically exceed Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company monitors this credit risk and makes adjustments to the concentrations as necessary. As of December 31, 2020 and 2019, the Company had deposits of $29.0 million and $7.5 million, respectively, which exceeded the FDIC insurance coverage amounts.

With respect to accounts receivable, credit risk is mitigated by the Company’s ongoing credit evaluation of its customers’ financial condition. No single customer accounted for more than 10 percent of trade receivables for the years ended December 31, 2020 and 2019. With respect to revenues, no single customer accounted for more than 10% of revenues for the years ended December 31, 2020, 2019 and 2018.

Other (Income) Expense, Net

Other (income) expense, net primarily consists of interest income, change in fair value associated with contingent considerations, loss on extinguishment of debt, and the impact of foreign currency transaction gains and losses associated with monetary assets and liabilities.

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes are provided for temporary differences in recognizing certain income, expense and credit items for financial reporting purposes and tax reporting purposes. Such deferred income taxes primarily relate to the difference between the tax bases of assets and liabilities and their financial reporting amounts. Deferred tax assets and liabilities are measured by applying enacted statutory tax rates applicable to the future years in which deferred tax assets or liabilities are expected to be settled or realized. Excess tax benefits and tax deficiencies are recognized in the income tax provision in the period in which they occur.

The Company records a valuation allowance when it determines, based on available positive and negative evidence, that it is more-likely-than-not that some portion or all of its deferred tax assets will not be realized. The Company determines the realizability of its deferred tax assets primarily based on the reversal of existing taxable temporary differences and projections of future taxable income (exclusive of reversing temporary differences and carryforwards). In evaluating such projections, the Company considers its history of profitability, the competitive environment, and general economic conditions. In addition, the Company considers the time frame over which it would take to utilize the deferred tax assets prior to their expiration.

For certain tax positions, the Company uses a more-likely-than-not threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured at the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense.

On December 22, 2017, U.S. tax reform legislation known as the Tax Cuts and Jobs Act (the “TCJA”) was signed into law. As of December 31, 2018, the Company’s accounting for the TCJA has been completed. The Company has determined the effects of certain provisions, including but not limited to: a reduction in the corporate tax rate from 35% to 21%, a limitation of the deductibility of certain officers’ compensation, a limitation on the current deductibility of net interest expense in excess of 30% of adjusted taxable income, a limitation of net operating losses generated after 2018 to 80% of taxable income, an incremental tax (base erosion anti-abuse or “BEAT”) on excessive amounts paid to foreign related parties, and a minimum tax on certain foreign earnings in excess of 10% of the foreign subsidiaries tangible assets (global intangible low- taxed income or “GILTI”). As part of its GILTI review, the Company has determined that it will account for GILTI income as it is generated (i.e., treat it as a period expense).

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (SEC Update). The update was issued to provide guidance on the income tax accounting implications of the TCJA. This includes the filing of financial statements with provisional amounts if companies are unable to finalize accounting provisions due to the changes enacted by the TCJA. In addition, subsequent changes to provisional amounts and disclosures are addressed in the ASU. The Company has completed the accounting for the effects of the Tax Act in its Consolidated Financial Statements with immaterial adjustments recorded as of December 31, 2018.

The COVID-19 pandemic has a global reach, and many countries are introducing measures that provide relief to taxpayers in a variety of ways. In March 2020, the U.S. government enacted tax legislation containing provisions to support businesses during the COVID-19 pandemic (the “CARES Act”), including deferment of the employer portion of certain payroll taxes, refundable payroll tax credits, and technical amendments to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s income tax provision for the year ended December 31, 2020.

Stock-Based Compensation

The Company accounts for stock-based compensation awards issued to its employees and members of its Board of Directors (the “Board”) in accordance with ASC 718, Compensation — Stock Compensation. ASC 718 requires that the cost resulting from all share-based payment transactions be recognized in the financial statements. This statement establishes fair value as the measurement objective in accounting for share-based payment arrangements and requires all entities to apply a fair value-based measurement method in accounting for these transactions with employees.

Stock-based compensation is measured at grant date based on the estimated fair value of the award and is expensed on a straight-line basis over the requisite service period net of an estimated forfeiture rate. The Company uses historical data to estimate forfeitures. The Company’s stock-based compensation awards relate to restricted stock units and stock options. The fair value of restricted stock unit awards is determined on the grant date based on the grant date stock price or a Monte Carlo Simulation model in instances where a market condition exists. For share-based awards that vest subject to the satisfaction of a market condition, the fair value measurement date for stock-based compensation is the date of the grant and the expense is recognized using the accelerated attribution method over the derived service period or upon achievement of the market condition. The fair value of stock option awards is determined on the grant date using the Black-Scholes Merton option pricing model. The option-pricing model requires a number of assumptions, of which the most significant are the expected stock price volatility, the expected option term and the fair market value of the Company’s common stock. Since there is no public market for the Company’s common stock, the Company bases its estimates of expected volatility on the median historical volatility of a group of publicly traded companies it believes are comparable to the Company, and uses the average of i) the weighted average vesting period and ii) the contractual life of the option, calculated using the “simplified method”. The simplified method allows for estimating the expected life based on an average of the option vesting term and option life, provided that all options meet certain criteria of “plain vanilla” options. The risk-free interest rate is based on the yield from U.S. treasury bonds as of the expected term. Additionally, the Company has assumed that dividends will not be paid.

Certain grants of stock options to executives contain certain vesting conditions, whereby, subject to the option holders continued employment with the Company, the award will vest upon the date the Company’s majority owner has received cumulative cash proceeds in respect of its investment in the Company equal to two times its aggregate cash investment in the Company. This is a market condition, but the requirement that the award vest on the basis of sufficient proceeds distributed to the Company’s majority owner represents a performance condition. During the years ended December 31, 2020, 2019 and 2018, the outcome of that performance condition is not considered probable, and therefore the Company did not recognize any expense associated with these stock options.

A certain grant of restricted stock units to an executive contains certain vesting conditions, whereby, subject to the award holders continued employment with the Company, the award will vest upon the date the Company’s achieves a certain fair market value for its common stock share price. The estimated fair value of the award was determined using a Monte Carlo Simulation model in accordance with ASC 718. During the year ended December 31, 2020, the market condition was satisfied; therefore, the Company recognized stock-based compensation expense of $0.7 million associated with these restricted stock units in General and administrative expense in the Consolidated Statements of Operations and Comprehensive Income.

Earnings Per Share

Basic and diluted earnings per share (“EPS”) are determined in accordance with ASC 260, Earnings per Share. Basic EPS is calculated by dividing net income by the weighted average number of common stock outstanding during the period. Diluted EPS is based upon the weighted average number of outstanding shares of common stock and dilutive common stock equivalents in the period. Common stock equivalents arise from dilutive stock options and restricted stock units and are computed using the treasury stock method. Anti-dilutive common stock equivalents are excluded from diluted EPS.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with certain new or revised accounting standards. As a result, the Company’s financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

These exemptions will apply until the Company no longer meets the requirement of being an emerging growth company. The Company will remain an emerging growth company until the earlier of (a) the last day of the fiscal year (i) following the fifth anniversary of the completion of this offering, (ii) in which the Company has total annual gross revenue of at least $1.07 billion or (iii) in which the Company is deemed to be a large accelerated filer, which means the market value of the Company’s common stock that is held by non-affiliates exceeds $700.0 million as of the last business day of the Company’s prior second fiscal quarter, and (b) the date on which the Company has issued more than $1.07 billion in non-convertible debt during the prior three-year period.

Offering Costs

Offering costs consist of expenses incurred during the Company’s preparation of its proposed initial public offering (“IPO”). These expenses include registration fees, filing fees, specific legal and accounting fees which are directly related to the Company’s efforts to raise capital through an IPO. The Company expenses offering costs as they are incurred. For the year ended December 31, 2020, offering costs were $3.6 million and recorded in General and administrative in the Consolidated Statement of Operations and Comprehensive Income.

Recently Issued Accounting Pronouncements

Financial Instruments — Credit Losses

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), 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 accounts receivable. This guidance is effective for annual reporting periods beginning after December 15, 2022 for non-public entities, including interim periods within that reporting period. Early adoption is permitted. The Company is currently in process of evaluating the impact of this standard on the Company’s Consolidated Financial Statements.

Cloud Computing

In August 2018, the FASB issued ASU No. 2018-15, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2020 for non-public entities, including interim reporting periods within those annual periods. The Company is currently in process of evaluating the impact of this standard on the Company’s Consolidated Financial Statements.

Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases Topic 842 (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. ASU 2016-02 is effective for fiscal years beginning after December 15, 2021 for non-public entities, with early adoption permitted. The Company is currently in process of evaluating the impact of this standard on the Company’s Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. This guidance is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements.

Reference Rate Reform

In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU No. 2020-04”). The amendment in this update provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment in this update applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendment does not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendment in this update is effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted this amendment on March 12, 2020. There was no impact to the Consolidated Financial Statements for the year ended December 31, 2020. The Company continues to monitor the transition of LIBOR to alternative reference rate measures.

Zentrick, headquartered in Ghent, Belgium is a digital video technology company that provides middleware solutions that increase the performance of online video advertising for brand advertisers, advertising platforms and publishers. This acquisition integrates technology into The Company’s suite of products related to advertising viewability specifically on video formats, a growing segment of the advertising market and critical for the delivery of verification services to social platform and connected TV. The aggregate purchase price consists of 1) $23.2 million paid in cash in closing, which excluded closing adjustments of approximately $0.2 million paid in April 2019 2) $0.1 million in holdback payment of which 50% was payable 12 months after the closing date, and the remaining 50% payable 24 months after the closing date 3) up to $17.3 million of performance-based deferred payments comprised of two components.

This decrease in fair value is due to actual 2020 revenues falling below the milestone target, a decrease in forecasted 2021 revenues for the 2021 revenue target, and changes in estimates related to the timing of achievement of two of the four technical milestones by approximately 6 months.

As of December 31, 2020, the technical milestone and revenue target components treated as compensation cost total $1.1 million, of which $0.8 million and $0.3 million and are included in Other Current Liabilities and Other Non-Current Liabilities, respectively, in the Consolidated Balance Sheets.

Upon acquisition, the Company used $0.6 million in cash to pay down Leiki’s vested stock options, which was included in the consideration transferred.

The total consideration transferred was $17.8 million. The cash consideration transferred was $13.9 million, including closing adjustments of $0.2 million that was paid in 2019. The holdback payment is not contingent on a future event occurring or condition being met but based solely on the passage of time, therefore the holdback payment is not accounted for as a contingent consideration. The holdback payment is initially measured at fair value on the acquisition date and the deferred payment is included in the total cash consideration transferred. During the year ended December 31, 2019, the company paid $2.0 million, and therefore the deferred payment balance was $2.0 million and $3.9 million as of December 31, 2019 and 2018, respectively, which is presented in liabilities in the Consolidated Balance Sheets. The remaining deferred payment of $2.0 million was fully paid during the year ended December 31, 2020.

The Company recognized a deferred tax liability of $0.9 million in relation to the intangible assets acquired.

The goodwill and identified intangible assets are not deductible for tax purposes. The Company incurred acquisition-related transaction costs of $0.5 million for the year ended December 31, 2018, which are included in General and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income.

The financial results of Leiki Oy were included in the Company’s Consolidated Financial Statements from the date of acquisition and the results included in the periods presented for the acquisition are not material. The pro forma impact of the Leiki acquisition is not material to the Company’s overall consolidated operating results and therefore is not presented.

The goodwill associated with the Company’s acquisitions include the acquired assembled work force, the value associated with the opportunity to leverage the work force to continue to develop the technology assets, as well as the ability to grow the Company through adding additional customer relationships or new solutions in the future.

Cash equivalents consisting of money market funds of $11.7 million and money market funds and time deposits of $2.5 million as of September 30, 2021 and December 31, 2020, respectively, were classified as Level 1 of the fair value hierarchy and valued using quoted market prices in active markets.

Contingent consideration relates to potential payments that the Company may be required to make associated with a business combination. To the extent that the valuations of these liabilities are based on inputs that are less observable or not observable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for measures categorized in Level 3.

Rollforward of the fair value measurements of the contingent consideration categorized with Level 3 inputs as of September 30, 2021 is as follows:

The fair value of the component of contingent consideration related to achievement of revenue targets have been estimated using a Monte Carlo model to simulate future performance of the acquired business under a risk-neutral framework; significant assumptions include a risk-adjusted discount rate of 13.5% and revenue volatility of 29.0%. The fair value of the component of contingent consideration related to achievement of four technical milestones have been estimated using situation-based modeling, which considers the probability-weighted present value of the expected payout amount.

On October 1, 2020, DoubleVerify Inc., as borrower (the “Borrower”), and MidCo, as guarantor, entered into an amendment and restatement agreement with the banks and other financial institutions party thereto, as lenders, and Capital One, National Association, as administrative agent, letter of credit issuer and swing lender, and others, to (i) amend and restate the Prior Credit Agreement as defined in the Prospectus (the Prior Credit Agreement, as amended and restated on October 1, 2020, the “Credit Agreement”) and (ii) replace the Prior Credit Facilities (as defined in the Prospectus) with a new senior secured revolving credit facility (the “New Revolving Credit Facility”) in an aggregate principal amount of $150.0 million (with a letter of credit facility of up to $15.0 million as a sublimit). Subject to certain terms and conditions, the Borrower is entitled to request additional term loan facilities or increases in the revolving credit commitments under the New Revolving Credit Facility. The New Revolving Credit Facility is payable in quarterly installments for interest, with the principal balance due in full at maturity on October 1, 2025. Additional fees paid quarterly include fees for the unused revolving facility and unused letter of credit. The commitment fee on any unused balance is payable periodically and may range from 0.25% to 0.40% based upon the total net leverage ratio. The New Revolving Credit Facility bears interest at LIBOR plus 2.25%, which may vary from time to time based on the Borrower’s total net leverage ratio calculated in accordance with the Credit Agreement.

The New Revolving Credit Facility contains a number of significant negative covenants. Subject to certain exceptions, these covenants require the Borrower to comply with certain requirements and restrictions to, among other things: incur indebtedness; create liens; engage in mergers or consolidations; make investments, loans and advances; pay dividends or other distributions and repurchase capital stock; sell assets; engage in certain transactions with affiliates; enter into sale and leaseback transactions; and make certain accounting changes. As a result of these restrictions, substantially all of the net assets of the Borrower are restricted from distribution to the Company or any of its holders of equity.

The New Revolving Credit Facility has a first priority lien on substantially all of the assets of MidCo, the Borrower and Ad-Juster, Inc., the Company’s indirect subsidiary. The New Revolving Credit Facility requires the Borrower to remain in compliance with a maximum total net leverage ratio and a minimum fixed charge coverage ratio as defined in the Credit Agreement.

As of September 30, 2021, the maximum total net leverage ratio and minimum fixed charge coverage ratio is 3.5x and 1.25x, respectively. The Borrower is in compliance with all covenants under the New Revolving Credit Facility as of September 30, 2021.

On April 30, 2021 the Company used a portion of the proceeds from the IPO and the concurrent private placement to pay the outstanding balance. As of September 30, 2021 and December 31, 2020, there was $0 outstanding and $22.0 million outstanding under the New Revolving Credit Facility, respectively.

8. Long-term Debt

On September 20, 2017, DoubleVerify, as borrower, and Midco, as guarantor, entered into a senior secured credit facility with Capital One, National Association consisting of a $30 million term loan facility, a revolving loan facility of up to $7 million (collectively, the “Old Credit Facilities”), and a letter of credit facility of up to $3 million as a sublimit of the revolving loan facility.

On July 31, 2018, DoubleVerify, as borrower, and Midco, as guarantor, entered into an amended and restated credit agreement (the “Prior Credit Agreement”) that amended and replaced the Old Credit Facilities, providing for a $55 million term loan facility with Capital One, National Association (the “Prior Term Loan”), a $20 million delayed draw term loan facility (the “Prior Delayed Draw Term Loan”), a revolving loan facility of up to $20 million (the “Prior Revolver” and, collectively with the Prior Term Loan and the Prior Delayed Draw Term Loan, the “Prior Credit Facilities”), and a letter of credit facility of up to $5 million as a sublimit of the Prior Revolver. The Prior Credit Facilities were used to refinance the Old Credit Facilities. The Prior Credit Facilities were payable in quarterly installments of $0.1 million, had an interest rate of LIBOR plus 3.75%, and were due in full at maturity on July 31, 2023.

On October 1, 2020, DoubleVerify, as borrower, and Midco, as guarantor, entered into an amendment and restatement agreement with the banks and other financial institutions party thereto, as lenders, and Capital One, National Association, as administrative agent, letter of credit issuer and swing lender, and others, to (i) amend and restate the Prior Credit Agreement (the Prior Credit Agreement, as amended and restated on October 1, 2020, the “Credit Agreement”) and (ii) replace the Prior Credit Facilities with a new senior secured revolving credit facility (the “New Revolving Credit Facility”) in an aggregate principal amount of $150.0 million (with a letter of credit facility of up to $15.0 million as a sublimit). Subject to certain terms and conditions, the Borrower is entitled to request additional term loan facilities or increases in the revolving credit commitments under the New Revolving Credit Facility. The New Revolving Credit Facility is payable in quarterly installments for interest, with the principal balance due in full at maturity on October 1, 2025. Additional fees paid quarterly include fees for the unused revolving facility and unused letter of credit. The commitment fee on any unused balance is payable periodically and may range from 0.25% to 0.40% based upon the total net leverage ratio. The New Revolving Credit Facility bears interest at LIBOR plus 2.25%, which may vary from time to time based on DoubleVerify’s total net leverage ratio calculated in accordance with the Credit Agreement.

In connection with the amended and restated agreement, the Company recorded a loss on extinguishment of $0.4 million in Interest expense (income) in the Consolidated Statements of Operations and Comprehensive Income.

The New Revolving Credit Facility contains a number of significant negative covenants. Subject to certain exceptions, these covenants require DoubleVerify to comply with certain requirements and restrictions to, among other things: incur indebtedness; create liens; engage in mergers or consolidations; make investments, loans and advances; pay dividends or other distributions and repurchase capital stock; sell assets; engage in certain transactions with affiliates; enter into sale and leaseback transactions; and make

certain accounting changes. As a result of these restrictions, substantially all of the net assets of DoubleVerify are restricted from distribution to the Company or any of its holders of equity.

The New Revolving Credit Facility has a first priority lien on substantially all of the assets of Midco, DoubleVerify and Ad-Juster, Inc., the Company’s indirect subsidiary. The New Revolving Credit Facility requires DoubleVerify to remain in compliance with a maximum total net leverage ratio and a minimum fixed charge coverage ratio as defined in the Credit Agreement.

Maximum total net leverage ratio is measured as consolidated total net indebtedness divided by consolidated adjusted earnings before interest, taxes, depreciation and amortization for the most recently ended twelve-month period for which financial statement have been delivered, as defined by the Credit Agreement.

Minimum fixed charge coverage ratio is measured as the ratio of consolidated adjusted earnings before interest, taxes, depreciation, and amortization for the most recently ended twelve-month period for which financial statements have been delivered less the sum of consolidated capital expenditures, taxes, management fees, and restricted payments to consolidated interest expense for such period plus schedule principal payments of indebtedness, as defined by the Credit Agreement.

As of December 31, 2020, the maximum total net leverage ratio and minimum fixed charge coverage ratio is 3.5x and 1.25x, respectively. DoubleVerify is in compliance with all covenants under the New Revolving Credit Facility as of December 31, 2020.

DoubleVerify drew $90.0 million on the New Revolving Credit Facility at the close of the transaction to pay off the Prior Credit Facilities balance of $73.6 million as of September 30, 2020 and fund the repurchase of a former executive’s time-based options, as described in Footnote 12, Stock-Based Compensation for more information. On December 24, 2020, DoubleVerify paid $68.0 million of its outstanding balance under the New Revolving Credit Facility. As of December 31, 2020, $22.0 million was outstanding under the New Revolving Credit Facility due at maturity.

Income Tax

9.     Income Tax

The Company’s quarterly income tax provision is calculated using an estimated annual effective income tax rate ("ETR") based on actual historical information and forward-looking estimates. The Company’s estimated annual ETR may fluctuate due to changes in forecasted annual pre-tax income, changes in the jurisdictional mix of forecasted pre-tax income, and changes to actual or forecasted permanent book to tax differences (e.g., non-deductible expenses). In addition, the Company’s ETR for a particular reporting period may fluctuate as the result of changes to the valuation allowance for net deferred tax assets, the impact of anticipated tax settlements with federal, state, or foreign tax authorities, or the impact of tax law changes. The Company identifies items that are unusual and non-recurring in nature and treat these as discrete events. The tax effect of these discrete events is booked entirely in the quarter in which they occur.

During the three and nine months ended September 30, 2021, the Company recorded an income tax provision of $3.3 million and $8.4 million, respectively, resulting in an effective tax rate of 29.2% and 89.3%, which includes an annualized effective tax provision of $3.3 million and $2.7 million (representing an effective tax rate of 29.2% and 29.1%) and discrete items relating primarily to transaction costs and state tax refunds of $0 and $5.6 million (representing an effective tax rate of 0.0% and 60.2%), respectively. During the three and nine months ended September 30, 2020, the Company recorded an income tax benefit of $1.4 million and an income tax provision of $2.0 million, respectively, resulting in an effective tax rate of (31.1%) and 13.8%, respectively. These effective tax rates differ from the U.S. federal statutory rate primarily due to the effects of differing treatment of transaction costs between book and tax, foreign tax rate differences, U.S. tax on foreign operations, and U.S. state/local taxes.

The COVID-19 (as defined herein) pandemic has a global reach, and many countries are introducing measures that provide relief to taxpayers in a variety of ways. In March 2020, the U.S. government enacted tax legislation containing provisions to support businesses during the COVID-19 pandemic (the “CARES Act”), including deferment of the employer portion of certain payroll taxes, refundable payroll tax credits, and technical amendments to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s income tax provision for the three and nine months ended September 30, 2021.

A valuation allowance has been established against a non-material amount of certain net foreign deferred tax assets and US tax loss carryforward. All other net deferred tax assets have been determined to be more likely than not realizable.

The Company and its subsidiaries file income tax returns with the Internal Revenue Service (“IRS”) and various state and international jurisdictions. The Company’s Israeli subsidiary is under audit by the Israeli Tax Authority for the 2016-2018 tax years. This examination may lead to ordinary course adjustments or proposed adjustments to the Company’s taxes. Aside from this, the Company is not currently under audit in any other jurisdiction.

On August 31, 2021, the Company acquired all of the outstanding stock of Meetrics, a German corporation, in a sale treated as a non-taxable event at the corporate level. The Company has calculated a preliminary tax basis balance sheet and deferred tax impact of the acquisition. The Company has recorded a deferred tax liability of $2.9 million relating to varying tax and book basis differences of intangible assets and goodwill.

In addition, Meetrics maintains net operating loss carryforwards of approximately $5.0 million through December 31, 2020. Based on a preliminary review of all positive and negative evidence, it appears to not be more likely than not that Meetrics will be able to utilize these loss carryforwards. Therefore, a deferred tax asset of $1.5 million has been recorded, which is fully offset by a valuation allowance.

Non‑cash compensation	(18.7)	%	0.1	%	—	%
Effective tax rate	(18.2)	%	34.1	%	(60.4)	%

Income Tax Provision (Benefit)

The Company’s effective tax rate for the year ended December 31, 2020 was lower than the U.S. federal statutory income tax rate primarily due to the impact of non-deductible non-cash compensation, certain tax credits, foreign taxes, provision to return adjustments and the impact of other permanent book-tax differences. For the year ended December 31, 2019, the Company’s effective tax rate was higher than the U.S. federal statutory income tax rate primarily due to the impact of state and local income taxes, certain tax credits, and the impact of other permanent book-tax differences. For the year ended December 31, 2018, the Company’s effective tax rate was lower than the U.S. federal statutory income tax rate primarily due to a one-time tax benefit of return to provision adjustments related to deductible transaction costs, offset by state and local income taxes, changes in statutory rates, and other permanent book-tax differences.

Deferred Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax reporting purposes. The following table details the components of deferred tax assets and liabilities as of December 31, 2020:

	As of December 31,
(in thousands)	2020		2019
Deferred tax assets:
Allowance for doubtful accounts	$	1,819	$	1,366
Accrued expenses and other		5,307		4,026
Net operating losses		1,298		1,978
Gross deferred tax assets		8,424		7,370
Valuation allowance		(484)		(88)
Net deferred tax assets	$	7,940	$	7,282
Deferred tax liabilities:
Purchased intangibles	$	(35,561)	$	(41,180)
Depreciation and amortization		(3,715)		(2,574)
Total deferred tax liabilities		(39,276)		(43,754)
Net deferred tax liabilitiy	$	(31,336)	$	(36,472)

The Company has not recorded a deferred tax liability for foreign withholding or other foreign local tax on the undistributed earnings from the Company’s international subsidiaries as such earnings are considered to be indefinitely reinvested.

Tax Valuation Allowance

The Company’s deferred tax assets and liabilities are primarily comprised of purchased intangibles, book to tax differences in depreciation and amortization, book and tax differing treatment of accruals, and net operating losses. As of each reporting date, management considers new evidence, both positive and negative, that could impact management’s view with regard to the future realization of deferred tax assets. As of December 31, 2020, (i) the Company’s taxable temporary differences will provide sufficient US future taxable income to realize the US deferred tax assets and (ii) the Company’s projected future pre-tax book income in the US and respective foreign countries is expected to provide sufficient taxable income to realize the deferred tax assets within each jurisdiction’s respective statutory carryforward period. Based on this analysis, the Company has concluded that it is more likely than not that the Company will realize most of its US and foreign deferred taxes assets. A valuation allowance is assessed to a small amount of foreign capital losses and US tax loss carryforwards.

Net Operating Loss and Credit Carryforwards

As of December 31, 2020, the Company had a Federal net operating loss carryforward of approximately $0.3 million and a state net operating loss carryforward of approximately $10.9 million. In addition, the Company had loss carryforwards for various foreign countries where the Company has business operations. The aggregate amount of foreign loss carryover is not material as of December 31, 2020. Federal net operating loss carryforwards can be used to offset against taxable income in the future and begin to expire in 2031. The Company utilized approximately $3.0 million and $2.7 million of Federal and state net operating loss carryforwards, respectively, in 2020. Utilization of Federal net operating loss carryforwards may be subject to annual limitations due to the “change in ownership” provisions of the Internal Revenue Code of 1986 and similar state provisions. The Company’s net operating loss carryforwards are subject to the annual limitation under Section 382 of the Internal Revenue Code.

Uncertain Tax Positions

The Company’s income tax returns are open to examination by federal and state authorities for the tax years ended December 31, 2016 and later. However, the Company believes that its tax positions are all highly certain of being upheld upon examination and intends to defend those positions if challenged by the Internal Revenue Services or another taxing jurisdiction.

For uncertain tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. The Company has unrecognized tax benefits, which are tax benefits related to uncertain tax positions which have been or will be reflected in income tax filings that have not been recognized in the financial statements due to potential adjustments by taxing authorities in the applicable jurisdictions. The Company’s liabilities for unrecognized tax benefits, which include interest and penalties, were $1.9 million and $0.6 million as of December 31, 2020 and 2019, respectively. The amount of unrecognized tax benefits that, if recognized, would affect the Company’s effective tax rate are $1.8 million and $0.5 million as of December 31, 2020 and 2019, respectively and include the federal tax benefit of state deductions. The Company anticipates that no unrecognized tax benefits will reverse during the next year due to the expiration of statutes of limitation.

Changes in the Company’s unrecognized tax benefits are as follows:

	For the Years

Employee Equity Incentive Plan

On September 20, 2017, the Company established its 2017 Omnibus Equity Incentive Program (the “2017 Plan”) which provides for the granting of equity based awards to certain employees, directors, independent contractors, consultants and agents. Under the 2017 Plan, the Company may grant non-qualified stock options, stock appreciation rights, restricted stock units, and other stock-based awards for up to 22,182 shares of common stock.

On April 19, 2021 the Company established its 2021 Omnibus Equity Incentive Plan (“2021 Equity Plan”). The maximum number of shares of common stock available for issuance under the 2021 Equity Plan is equal to the sum of (i) 30,000 shares of common stock and (ii) an annual increase on the first day of each year beginning in 2022 and ending in and including 2031, equal to the lesser of (A) five percent (5%) of the outstanding shares of common stock on the last day of the immediately preceding fiscal year and (B) such lesser amount as determined by the Board’s compensation committee. The 2021 Equity Plan provides for the grant of stock options (including qualified incentive stock options and nonqualified stock options), stock appreciation rights, restricted stock, restricted stock units, dividend equivalents, and other stock or cash settled incentive awards. Any shares covered by an award, or portion of an award, granted under the 2021 Equity Plan that expires or is forfeited, canceled, cash-settled, or otherwise terminated for any reason will again be available for the grant of awards under the 2021 Equity Plan.

Options become exercisable subject to vesting schedules up to four years from the date of the grant and subject to certain timing restrictions upon an employee’s separation of service and no later than 10 years after the grant date.

Restricted stock units are subject to vesting schedules up to four years from the date of the grant and subject to certain timing restrictions upon an employee’s separation.

A summary of stock option activity as of and for the nine months ended September 30, 2021 and December 31, 2020 is as follows:

Stock options include grants to executives that contain both market-based and performance-based vesting conditions. There were no stock options granted that contain both market-based and performance-based vesting conditions during the nine months ended September 30, 2021. As of September 30, 2021, 3,433 market-based and performance-based awards were outstanding. As of September 30, 2021, the Company did not consider the performance condition to be probable and did not recognize any expense associated with these options.

The weighted average grant date fair value of options granted during the nine months ended September 30, 2021 and 2020 was $12.85 and $2.40, respectively. The total intrinsic value of options exercised during the nine months ended September 30, 2021 and 2020 was $50.5 million and $0.5 million, respectively.

The fair market value of each option granted during the nine months ended September 30, 2021 has been estimated on the grant date using the Black-Scholes-Merton option-pricing model with the following assumptions:

	2021
Risk - free interest rate (percentage)	0.6. - 1.1
Expected term (years)	5.9 - 6.1
Expected dividend yield (percentage)	—
Expected volatility (percentage)	42.1 - 43.6

The Company’s board of directors (the “Board”) did not declare or pay dividends of the Company’s common or preferred stock during the nine months ended September 30, 2021 or during the nine months ended September 30, 2020.

A summary of restricted stock unit activity as of and for the nine months ended September 30, 2021 and December 31, 2020 is as follows:

Employee Stock Purchase Plan

In March 2021, the Board approved the Company’s 2021 Employee Stock Purchase Plan (“ESPP”), and employees became eligible to enroll in August 2021. The ESPP qualifies as an “employee stock purchase plan” under Section 423 of the U.S. Internal Revenue Code of 1986, as amended.

The Company reserved 3,000 shares of common stock for sale under the ESPP. The share reserve increases on the first day of each calendar year beginning on January 1, 2022 and ending on and including January 1, 2031, equal to the lesser of (i) one percent (1%) of the aggregate number of shares of common stock outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares of common stock as is determined by the Board.

Purchases are accomplished through participation in discrete offering periods. Currently, the ESPP is available only to U.S. based employees; the Company is reviewing offering the ESPP program to employees in non-U.S. jurisdictions. The first offering and purchase period began on September 1, 2021 and will end on November 30, 2021. The Company expects the program to continue consecutively for six-month offering periods (commencing on December 1, 2021) for the foreseeable future.

Under the ESPP, eligible employees are able to acquire shares of the Company’s common stock by accumulating funds through payroll deductions. Company employees in the United States generally are eligible to participate in the ESPP if they are a full-time employee and have completed six months of continuous service with the Company as of the last day of the enrollment period. Eligible employees are able to select a rate of payroll deduction between 1% and 15% of their compensation, up to a $25 annual contribution limit. The purchase price for shares of common stock purchased under the ESPP is 85% of the lesser of the fair market value of the common stock on (i) the first trading day of the applicable offering period and (ii) the last trading day of the applicable offering period. An employee’s participation automatically ends upon termination of employment for any reason. A participant may cancel enrollment or lower their contributions once during an offering period, but no later than 30 days before the end of an offering period. Upon the termination of an employee’s participation in the ESPP, payroll deductions will be stopped and refunded.

Stock-based compensation expense for the ESPP is recognized on a straight-line basis over the requisite service period of each award. The ESPP also has a six-month holding period after the purchase date of the offering period. Stock-based compensation expense related to ESPP totaled less than $0.1 million for the three and nine months ended September 30, 2021.

12. Stock-Based Compensation

Employee Stock Option Plan

On September 20, 2017, the Company established an Equity Incentive Program (the “Plan”) which provides for the granting of incentive and nonqualified stock options to certain employees, directors, independent contractors, consultants and agents. Under the Plan, the Company may grant non-qualified stock options, stock appreciation rights, restricted stock units, and other stock-based awards up to 22,182 shares of Common Stock.

Options become exercisable subject to vesting schedules up to four years from the date of the grant and subject to certain timing restrictions upon an employee’s separation of service and no later than 10 years after the grant date.

Restricted stock units are subject to vesting schedules up to two years from the date of the grant and subject to certain timing restrictions upon an employee’s separation.

A summary of stock option activity as of and for the years ended December 31, 2020, 2019 and 2018 is as follows:

Stock options include grants to executives that contain both market-based and performance-based vesting conditions. During the year ended December 31, 2020, the Company granted 600 stock options that contain both market-based and performance-based vesting conditions and 167 of restricted stock units that contain market-based vesting conditions. The Company repurchased and cancelled 956 of stock options that contain both market-based and performance-based vesting conditions resulting in $14.5 million in incremental cash-based compensation expense related to the transaction, and vested 167 of restricted stock units with market-based vesting conditions. As of December 31, 2020, 3,433 market-based and performance-based awards were outstanding. As of December 31, 2020, the Company did not consider the performance condition to be probable and did not recognize any expense associated with those options.

The Company repurchased and cancelled 2,606 vested stock options from a former executive during the year ended December 31, 2020 for an aggregate purchase price of approximately $15.5 million recorded in Additional Paid-in Capital on the Company’s Consolidated Balance Sheets.

The weighted average grant date fair value of options granted for the years ended December 31, 2020, 2019, and 2018 was $2.67, $1.41 and $0.51, respectively. The total intrinsic value of options exercised during the years ended December 31, 2020, 2019 and 2018 was $3.6 million, $0.3 million and nil, respectively.

The fair market value of each option granted for the years presented has been estimated on the grant date using the Black-Scholes-Merton option-pricing model with the following assumptions:

	2020	2019	2018

Capital Leases

As of September 30, 2021, the Company had seven lease agreements for certain equipment which provide for the transfer of ownership at the end of the lease term or are for underlying assets that will have an insignificant fair value at the end of the lease term.

The following is a schedule of future minimum lease payments under these agreements (including interest) as of September 30, 2021.

Contingencies

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. The Company records liabilities for contingencies including legal costs when it is probable that a liability has been incurred and when the amount can be reasonably estimated. Legal costs are expensed as incurred. 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 effect on the Company’s business, financial condition, results of operations or cash flows.

With respect to potential payments due related to the Zentrick acquisition, discussed in Footnote 4, Business Combinations, the Company and the Zentrick selling stockholders are currently in discussions to negotiate the early termination of the Zentrick Deferred Payment Terms and resolution of the contingent payments due for both the technical milestones and revenue targets. The Company believes the total of approximately $2.8 million for these potential payments reflected in the Condensed Consolidated Balance Sheet as contingent consideration current and other current liabilities reflect the Company’s estimated obligations under the stock purchase agreement entered into in connection with the transaction, as of September 30, 2021. In efforts to terminate early the Zentrick Deferred Payment Terms, the Company believes payment between $2.8 million and $5.5 million is possible, with no amount within the range being a better estimate than the amount recorded on the Condensed Consolidated Balance Sheets.

Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and measurement of items including, but not limited to: revenue recognition criteria including the determination of principal versus agent revenue considerations, income taxes, the valuation and recoverability of goodwill and intangible assets, the assessment of potential loss from contingencies, the allowance for doubtful accounts, and assumptions used in determining the fair value of stock-based compensation. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. These estimates are based on the information available as of the date of the Condensed Consolidated Financial Statements.

Segment Reporting

Segment Reporting

The Company’s operating segments are determined based on the units that constitute a business for which discrete financial information is available and for which operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”). The CODM is the highest level of management responsible for assessing the Company’s overall performance and making operational decisions. The Company operates in one single operating and reportable segment.

Fair Value Measurements

Fair Value Measurements

The Company evaluates the fair value of certain assets and liabilities using the fair value hierarchy. Fair value is an exit price representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company applies the three-tier GAAP value hierarchy which prioritizes the inputs used in measuring fair value as follows:

Level 1 — observable inputs such as quoted prices in active markets;

Level 2 — inputs other than the quoted prices in active markets that are observable either directly or indirectly;

Level 3 — unobservable inputs of which there is little or no market data, which require the Company to develop its own assumptions.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measure.

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.

Foreign Currency

Foreign Currency

A majority of the Company’s revenues are generated in U.S. dollars. In addition, most of the Company’s costs are denominated and determined in U.S. dollars. Thus, the reporting currency of the Company is the U.S. dollar.

The functional currency of the Company’s foreign subsidiaries is generally the local currency. The assets and liabilities of subsidiaries whose functional currency is a foreign currency are translated at the period-end exchange rates. Income statement items are translated at the average monthly rates for the year. The resulting translation adjustment is recorded as a component of accumulated other comprehensive (income) loss and is included in the Consolidated Statement of Stockholders’ Equity.

For the years ended December 31, 2020, 2019, and 2018, the Company recorded an aggregate transaction loss of $0.5 million, an aggregate transaction gain of less than $0.1 million, and an aggregate transaction loss of $0.5 million, respectively. The aggregate transaction gains or losses were recorded in the Consolidated Statement of Operations and Comprehensive Income.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all short-term highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. Pursuant to the Company’s investment policy, its surplus funds are kept as cash or cash equivalents in money market and savings accounts to reduce its exposure to market risk.

Trade Receivables Net of Allowances for Doubtful Accounts

Trade Receivables Net of Allowances for Doubtful Accounts

Trade receivables are non-interest bearing and are stated at gross invoice amounts. A receivable is recorded when the Company has an unconditional right to receive payment based on the satisfaction of performance obligations, such that only the passage of time is required before consideration is due, regardless of whether amounts are billed or unbilled. Included in trade receivables on the Consolidated Balance Sheets are unbilled receivable balances which have not yet been invoiced.

The Company estimates its allowance for doubtful accounts by evaluating specific accounts where information indicates the customers may have an inability to meet financial obligations, such as bankruptcy proceedings and receivable amounts outstanding for an extended period beyond contractual terms. In these cases, the Company uses assumptions and judgment, based on the best available facts and circumstances, to either record a specific allowance against these customer balances or to write the balances off.

Write-offs of accounts receivable are taken in the period when the Company has exhausted its efforts to collect overdue and unpaid receivables or otherwise has evaluated other circumstances that indicate that the Company should abandon such efforts.

Prepaid Expenses and Other Current Assets

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets on the Consolidated Balance Sheets consistent primarily of prepaid taxes, other general prepaid expenses, restricted cash, and value added tax assets. Any expenses paid prior to the related services being rendered are recorded as prepaid expenses and amortized over the period of service.

Restricted cash represents amounts pledged as collateral for certain agreements with third parties. Upon satisfying the terms of the agreements, the funds are expected to be released and available for use by the Company. As of December 31, 2020 and 2019, the Company had less than $0.1 million and $0.4 million of restricted cash, respectively.

As of December 31, 2020 and 2019, the Company had prepaid income taxes of $10.4 million and $0.9 million, respectively.

Property, Plant and Equipment, Net

Property, Plant and Equipment, Net

Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the following estimated useful lives of the assets:

Computer equipment	3 years
Office furniture and equipment	4 ‑ 7 years
Leasehold improvements	4 ‑ 6 years

Assets under capital leases are recorded at their net present value at the inception of the lease. Assets under capital leases and leasehold improvements are amortized over the shorter of the related lease terms or their useful lives.

Expenditures which significantly improve or extend the life of an asset are capitalized, while charges for routine maintenance and repairs are expensed during the year incurred.

Capitalized Software

Capitalized Software

Capitalized software, which is included in Property, plant and equipment, net, consists of costs to purchase and develop internal-use software, which the Company uses to provide services to its customers. The costs to purchase and develop internal-use software are capitalized from the time that the preliminary project stage is completed, and it is considered probable that the software will be used to perform the function intended. These costs include personnel and related employee benefits for employees directly associated with the software development and external costs of the materials or services consumed in developing or obtaining the software. Any costs incurred during subsequent efforts to upgrade and enhance the functionality of the software are also capitalized. Once this software is ready for use in the Company’s products, these costs are amortized on a straight-line basis over the estimated useful life of the software, which is 3 years. During the years ended December 31, 2020 and December 31, 2019, the Company capitalized $5.2 million and $3.1 million in internal-use software cost, respectively. Amortization expense was $1.4 million and $0.4 million on capitalized internal-use software costs during the years ended December 31, 2020 and December 31, 2019, respectively. This is included within depreciation expense on Property, plant and equipment, net. The Company did not capitalize software costs and recognize amortization expense in 2018 as the Company did not have a process in place to track costs.

Leases

Leases

The Company leases its facilities and meets the requirements to account for these leases as operating leases. For facility leases that contain rent escalations or rent concession provisions, the Company records its lease expense during the lease term on a straight-line basis over the term of the lease. The Company records the difference between the rent paid and the straight-line rent as a deferred rent liability. Leasehold improvements funded by landlords or allowances are recorded as leasehold improvement assets and a deferred rent liability which is amortized as a reduction of rent expense over the lesser of the term of the lease or life of the asset.

The Company leases computer equipment that meet the requirements to account for these as capital leases. The Company records capital leases as an asset and an obligation at an amount equal to the present value of the minimum lease payments as determined at the beginning of the lease term. Depreciation of capitalized leased assets is computed over their useful life and is included in depreciation expense.

Business Combinations

Business Combinations

The Company recognizes assets acquired and liabilities assumed at their fair value on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill. Acquisition-related costs are expensed as incurred.

Goodwill

Goodwill

Goodwill represents the excess of purchase price over the fair value of tangible net assets and identifiable intangible assets of the businesses acquired.

The valuation of goodwill involves the use of management’s estimates and assumptions. The carrying value of goodwill is not amortized, but rather, is evaluated for impairment at least annually, as of October 1, and, additionally on an interim basis, whenever events or changes in circumstances indicate that the carrying amount of goodwill will not be recoverable. The Company performs this evaluation by comparing the fair value of a reporting unit to its carrying value, including goodwill recorded by the reporting unit.

The Company has a single reporting unit. The Company’s review for impairment includes an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs a quantitative goodwill impairment test, which compares the fair value of the reporting unit with its carrying amounts. The Company estimates the fair value of its reporting unit considering both income and market-based approaches. The estimated fair value of a reporting unit is determined based on assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values.

The Company completed its analyses for each of the years ended December 31, 2020, 2019, and 2018 and determined that there was no impairment of goodwill.

Intangible Assets, Net

Intangible Assets, Net

Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives.

The estimated useful lives of the Company’s finite-lived intangible assets are as follows:

Technology	4 ‑ 8 years
Customer relationships	5 ‑ 12 years
Trademarks	5 ‑ 15 years

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

Long-lived assets, such as property and equipment and intangible assets subject to depreciation and amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful life is shorter than the Company had originally estimated. Recoverability of these assets is measured by comparison of the carrying amount of each asset or asset group to the future undiscounted cash flows the asset or asset group is expected to generate over their remaining lives. If the asset or asset group is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset or asset group. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the new shorter useful life. There were no impairments recognized for the years ended December 31, 2020, 2019 and 2018.

Debt Issuance Costs

Debt Issuance Costs

Prior to the Company’s New Revolving Credit Facility, as described in Footnote 8, Long-term Debt, the Company reflected debt issuance costs for the Prior Credit Facilities in the Consolidated Balance Sheets as a direct deduction from the gross amount, consistent with the presentation of a debt discount. Debt issuance costs for the Prior Credit Facilities were amortized to interest expense over the term of the underlying debt instrument, utilizing the effective interest rate method. For the New Revolving Credit Facility, debt issuance costs meet the definition of an asset and are recorded in the Consolidated Balances Sheets in Other Non-Current Assets. Debt issuance costs incurred for the New Revolving Credit Facility that were capitalized total $0.9 million. Debt issuance costs for the New Revolving Credit Facility are amortized to interest expense over the contractual term of the underlying debt instrument on a straight-line basis through the maturity date of the instrument of October 1, 2025. As of December 31, 2020 and December 31, 2019, remaining debt issuance costs were $1.4 million and $0.9 million, respectively.

Revenue Recognition

Revenue Recognition

On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (ASC 606), using the modified retrospective method. The adoption of ASU 2014-09 did not result in a material change in the timing or amount of revenue recognized. Prior to January 1, 2019, the Company recognized its revenues in accordance with ASC 605, Revenue Recognition, when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectability is probable. Results for reporting periods beginning after January 1, 2019 are presented in accordance with ASC 606, while prior period amounts have not been adjusted.

In accordance with ASC 606, the Company recognizes revenue under the core principle to depict the transfer of control to its customers in an amount reflecting the consideration to which it expected to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

The Company’s contracts with customers may include multiple promised services, consisting of the various impression measurement services the Company offers. For all revenue channels, the Company identifies performance obligations by evaluating whether the promised goods and services are capable of being distinct and distinct within the context of the contract at contract inception. Promised goods and services that are not distinct at contract inception are combined as one performance obligation. Once the Company identifies the performance obligations, the Company will determine the transaction price based on contractually fixed amounts. The Company allocates the transaction price to each performance obligation based on the standalone selling price.

The major sources of revenue include Advertiser Direct, Advertiser Programmatic, and Supply-Side Customers.

Advertiser Direct and Advertiser Programmatic Revenue

For Advertiser Direct revenue, advertisers can purchase the Company’s services to measure the quality and performance of ads purchased directly from digital properties, including publishers and social media platforms. Advertisers are provided access to the Company’s platform through the Company’s proprietary self-service software that provides the Company’s customers with access to data on all their digital ads and enables them to make changes to their ad strategies. In these arrangements, the customer pays a fee to the Company based on the ads measured.

For Advertiser Programmatic revenues, advertisers purchase the Company’s services through programmatic platforms to evaluate the quality of ad inventories before they are purchased. Advertisers may purchase the Company’s service offering through a Demand-Side Platform that manages various ad campaign auctions and inventory on behalf of the advertisers. Customers elect to use the Company’s service of evaluating the quality of advertising inventory up for bid on an advertising exchange. The ability to provide these services to customers requires that the Company enter into product integration agreements with Demand-Side Platforms who in turn make the Company’s services available to advertisers. In these arrangements, the customer pays a fee to the Company (collected by the Demand-Side Platform) for the successful execution of the purchase of advertising inventory on an exchange.

For Advertiser Direct and Advertiser Programmatic revenues, contracts with multiple performance obligations typically consist of services aimed at advertisers to help evaluate and ensure the success of a brand campaign by measuring authentic impressions. These services are generally delivered together as impressions are measured. Revenue is recognized over time, as the Company is providing services that the customer is continuously consuming and receiving benefit from or upon completion of the service. The Company considers the “right to invoice” practical expedient appropriate in the context of the Company’s contracts as this directly corresponds to the value of the Company’s performance to date. In this case, the Company’s pricing structure is (1) solely variable on the basis of the customer’s usage of the Company’s services, (2) is priced at a fixed rate per usage and (3) gives the entity the right to invoice the customer for its usage as it occurs.

Supply-Side Customers

Supply-Side Customer revenues consist of arrangements with publishers and other supply-side customers to provide them with software solutions and data analytics to enable them to maximize revenue from their digital advertising inventory. Certain arrangements include minimum guaranteed fees that reset monthly and are recognized on a straight-line basis over the access period, which is usually twelve months. For contracts that contain overages, once the minimum guaranteed amount is achieved, overages are recognized as earned over time based on a tiered pricing structure. Such revenues are recognized on an input method time-elapsed basis, as the Company is providing services that the customer is continuously consuming and receiving benefit from, and such recognition best depicts the transfer of control to the customer. Overages give rise to variable consideration that is allocated to the distinct periods to which the overage relates.

Transactions that Involve Third Parties

For transactions that involve third parties, the Company evaluates which party in the arrangement obtains control of the Company’s services (and is therefore the Company’s customer), which impacts whether the Company reports as revenue the gross amounts paid by the advertiser through the Demand-Side Platform or the net amount paid by the Company’s Demand-Side Platform partners. For certain arrangements, advertisers (“customers”) may purchase the Company’s service offering through a Demand-Side Platform that manages various ad campaign auctions and inventory on behalf of the advertisers. Customers elect to use the Company’s service of evaluating the quality of advertising inventory up for bid on an advertising exchange. The ability to provide these services to customers requires that the Company enter into product integration agreements with Demand-Side Platforms who in turn make the Company’s services available to advertisers. In these arrangements, the customer pays a fee to the Company (collected by the Demand-Side Platform) for the successful execution of the purchase of advertising inventory on an exchange. In these transactions, the Company transfers control of the Company’s services directly to the advertiser (who is the Company’s customer) and therefore revenue is recognized for the gross amount paid by the advertiser for the Company’s services. Specifically, the Company transfers control of the data that is influencing the purchasing decisions directly to the customer and the Company is primarily responsible for providing these services to the customer. That is, control of these services (or a right to these services) does not transfer to the Demand-Side Platform before they are transferred to the Company’s customers. Further, the Company has latitude in establishing the

sales price with those customers as there is a fixed retail rate card that is included in the product integration agreements with the Demand-Side Platforms or are governed by contracts in place with the customers. Accordingly, the Company records revenue for the gross amounts paid by advertisers for these services and records the amounts retained by the Demand-Side Platforms as a cost of revenue.

Contract assets relate to the Company’s conditional right to consideration for completed performance under the contract (e.g., unbilled receivables) and are included in Trade receivables, net of allowance for doubtful accounts.

Costs to Fulfill or Obtain a Contract

The Company recognizes direct fulfillment costs as an expense when incurred. These costs include commission programs to compensate employees for generating sales orders under the Company’s master services agreements or integration agreements, and are included in Sales, marketing, and customer support. The Company has not incurred incremental costs to obtain contracts during the periods ended December 31, 2020, 2019 and 2018, respectively.

Operating Expenses

Operating Expenses

Cost of revenue includes platform hosting fees, data center costs, software and other technology expenses and other costs directly associated with data infrastructure. Cost of revenue also includes personnel costs including salaries, bonuses, stock-based compensation, employee benefit costs, commissions related to revenue share arrangements with Demand-Side Platforms, and allocated overhead expenses for personnel who provide the Company’s customers with support in implementing and using the Company’s software platform. Cost of revenues excludes depreciation and amortization.

Product development expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs, and allocated overhead expenses inclusive of engineering, product and technical operation expenses, third-party consultant costs associated with the ongoing research, development and maintenance of the Company’s software platform. 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 and included in Property, plant and equipment, net on the Company’s Consolidated Balance Sheets.

Sales, marketing and customer support expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs, commission costs, and allocated overhead expenses for the Company’s sales, marketing and customer support personnel. Sales, marketing, and customer support expense also include costs for market development programs, advertising costs, attendance at events and trade shows, promotional and other marketing activities. Advertising costs include expenses associated with direct marketing but exclude the costs of attendance at events and trade shows. Advertising costs were less than $0.1 million, $0.1 million, and nil for the years ended December 31, 2020, 2019 and 2018, respectively. Commissions costs are expensed as incurred.

General and administrative expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs and other overhead expenses associated with the Company’s executive, finance, legal, human resources, compliance, and other administrative personnel, as well as accounting, tax, and legal professional services fees, rent, bad debt expense and other overhead expense related to human resource and finance activities, as well as other corporate costs including offering costs.

For the year ended December 31, 2020, the Company recorded $0.9 million in recoveries from business interruption insurance classified in General and administrative in the Consolidated Statement of Operations and Comprehensive Income. The insurance recovery related to investigating and remediating certain information technology and cybersecurity matters that occurred in the year. There were no recoveries from business interruption insurance for the years ended December 31, 2019 and 2018, respectively.

Concentrations of Credit Risk

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and trade receivables. The Company maintains cash deposits with financial institutions that, from time to time, exceed applicable insurance limits. The Company reduces this risk by maintaining such deposits with high quality financial institutions that management believes are creditworthy. Cash and cash equivalents are maintained with several financial institutions domestically and

internationally. The combined account balances held on deposit at each institution typically exceed Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company monitors this credit risk and makes adjustments to the concentrations as necessary. As of December 31, 2020 and 2019, the Company had deposits of $29.0 million and $7.5 million, respectively, which exceeded the FDIC insurance coverage amounts.

With respect to accounts receivable, credit risk is mitigated by the Company’s ongoing credit evaluation of its customers’ financial condition. No single customer accounted for more than 10 percent of trade receivables for the years ended December 31, 2020 and 2019. With respect to revenues, no single customer accounted for more than 10% of revenues for the years ended December 31, 2020, 2019 and 2018.

Other (Income) Expense, Net

Other (Income) Expense, Net

Other (income) expense, net primarily consists of interest income, change in fair value associated with contingent considerations, loss on extinguishment of debt, and the impact of foreign currency transaction gains and losses associated with monetary assets and liabilities.

Income Taxes

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes are provided for temporary differences in recognizing certain income, expense and credit items for financial reporting purposes and tax reporting purposes. Such deferred income taxes primarily relate to the difference between the tax bases of assets and liabilities and their financial reporting amounts. Deferred tax assets and liabilities are measured by applying enacted statutory tax rates applicable to the future years in which deferred tax assets or liabilities are expected to be settled or realized. Excess tax benefits and tax deficiencies are recognized in the income tax provision in the period in which they occur.

The Company records a valuation allowance when it determines, based on available positive and negative evidence, that it is more-likely-than-not that some portion or all of its deferred tax assets will not be realized. The Company determines the realizability of its deferred tax assets primarily based on the reversal of existing taxable temporary differences and projections of future taxable income (exclusive of reversing temporary differences and carryforwards). In evaluating such projections, the Company considers its history of profitability, the competitive environment, and general economic conditions. In addition, the Company considers the time frame over which it would take to utilize the deferred tax assets prior to their expiration.

For certain tax positions, the Company uses a more-likely-than-not threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured at the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense.

On December 22, 2017, U.S. tax reform legislation known as the Tax Cuts and Jobs Act (the “TCJA”) was signed into law. As of December 31, 2018, the Company’s accounting for the TCJA has been completed. The Company has determined the effects of certain provisions, including but not limited to: a reduction in the corporate tax rate from 35% to 21%, a limitation of the deductibility of certain officers’ compensation, a limitation on the current deductibility of net interest expense in excess of 30% of adjusted taxable income, a limitation of net operating losses generated after 2018 to 80% of taxable income, an incremental tax (base erosion anti-abuse or “BEAT”) on excessive amounts paid to foreign related parties, and a minimum tax on certain foreign earnings in excess of 10% of the foreign subsidiaries tangible assets (global intangible low- taxed income or “GILTI”). As part of its GILTI review, the Company has determined that it will account for GILTI income as it is generated (i.e., treat it as a period expense).

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (SEC Update). The update was issued to provide guidance on the income tax accounting implications of the TCJA. This includes the filing of financial statements with provisional amounts if companies are unable to finalize accounting provisions due to the changes enacted by the TCJA. In addition, subsequent changes to provisional amounts and disclosures are addressed in the ASU. The Company has completed the accounting for the effects of the Tax Act in its Consolidated Financial Statements with immaterial adjustments recorded as of December 31, 2018.

The COVID-19 pandemic has a global reach, and many countries are introducing measures that provide relief to taxpayers in a variety of ways. In March 2020, the U.S. government enacted tax legislation containing provisions to support businesses during the COVID-19 pandemic (the “CARES Act”), including deferment of the employer portion of certain payroll taxes, refundable payroll tax credits, and technical amendments to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s income tax provision for the year ended December 31, 2020.

Stock-Based Compensation

Stock-Based Compensation

The Company accounts for stock-based compensation awards issued to its employees and members of its Board of Directors (the “Board”) in accordance with ASC 718, Compensation — Stock Compensation. ASC 718 requires that the cost resulting from all share-based payment transactions be recognized in the financial statements. This statement establishes fair value as the measurement objective in accounting for share-based payment arrangements and requires all entities to apply a fair value-based measurement method in accounting for these transactions with employees.

Stock-based compensation is measured at grant date based on the estimated fair value of the award and is expensed on a straight-line basis over the requisite service period net of an estimated forfeiture rate. The Company uses historical data to estimate forfeitures. The Company’s stock-based compensation awards relate to restricted stock units and stock options. The fair value of restricted stock unit awards is determined on the grant date based on the grant date stock price or a Monte Carlo Simulation model in instances where a market condition exists. For share-based awards that vest subject to the satisfaction of a market condition, the fair value measurement date for stock-based compensation is the date of the grant and the expense is recognized using the accelerated attribution method over the derived service period or upon achievement of the market condition. The fair value of stock option awards is determined on the grant date using the Black-Scholes Merton option pricing model. The option-pricing model requires a number of assumptions, of which the most significant are the expected stock price volatility, the expected option term and the fair market value of the Company’s common stock. Since there is no public market for the Company’s common stock, the Company bases its estimates of expected volatility on the median historical volatility of a group of publicly traded companies it believes are comparable to the Company, and uses the average of i) the weighted average vesting period and ii) the contractual life of the option, calculated using the “simplified method”. The simplified method allows for estimating the expected life based on an average of the option vesting term and option life, provided that all options meet certain criteria of “plain vanilla” options. The risk-free interest rate is based on the yield from U.S. treasury bonds as of the expected term. Additionally, the Company has assumed that dividends will not be paid.

Certain grants of stock options to executives contain certain vesting conditions, whereby, subject to the option holders continued employment with the Company, the award will vest upon the date the Company’s majority owner has received cumulative cash proceeds in respect of its investment in the Company equal to two times its aggregate cash investment in the Company. This is a market condition, but the requirement that the award vest on the basis of sufficient proceeds distributed to the Company’s majority owner represents a performance condition. During the years ended December 31, 2020, 2019 and 2018, the outcome of that performance condition is not considered probable, and therefore the Company did not recognize any expense associated with these stock options.

A certain grant of restricted stock units to an executive contains certain vesting conditions, whereby, subject to the award holders continued employment with the Company, the award will vest upon the date the Company’s achieves a certain fair market value for its common stock share price. The estimated fair value of the award was determined using a Monte Carlo Simulation model in accordance with ASC 718. During the year ended December 31, 2020, the market condition was satisfied; therefore, the Company recognized stock-based compensation expense of $0.7 million associated with these restricted stock units in General and administrative expense in the Consolidated Statements of Operations and Comprehensive Income.

Earnings Per Share

Earnings Per Share

Basic and diluted earnings per share (“EPS”) are determined in accordance with ASC 260, Earnings per Share. Basic EPS is calculated by dividing net income by the weighted average number of common stock outstanding during the period. Diluted EPS is based upon the weighted average number of outstanding shares of common stock and dilutive common stock equivalents in the period. Common stock equivalents arise from dilutive stock options and restricted stock units and are computed using the treasury stock method. Anti-dilutive common stock equivalents are excluded from diluted EPS.

Emerging Growth Company Status

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with certain new or revised accounting standards. As a result, the Company’s financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

These exemptions will apply until the Company no longer meets the requirement of being an emerging growth company. The Company will remain an emerging growth company until the earlier of (a) the last day of the fiscal year (i) following the fifth anniversary of the completion of this offering, (ii) in which the Company has total annual gross revenue of at least $1.07 billion or (iii) in which the Company is deemed to be a large accelerated filer, which means the market value of the Company’s common stock that is held by non-affiliates exceeds $700.0 million as of the last business day of the Company’s prior second fiscal quarter, and (b) the date on which the Company has issued more than $1.07 billion in non-convertible debt during the prior three-year period.

Offering Costs

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with certain new or revised accounting standards.

Financial Instruments - Credit Losses

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), 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 accounts receivable. This guidance is effective for annual reporting periods beginning after December 15, 2022 for non-public entities, including interim periods within that reporting period. Early adoption is permitted and the update allows for a modified retrospective method of adoption. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Cloud Computing

In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2020 for non-public entities, and interim periods within annual periods beginning after December 15, 2021. The update allows for a retrospective or prospective method of adoption.

The Company intends to adopt amendment ASU No. 2018-15 on December 31, 2021 using a prospective approach. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases Topic 842 (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. In July 2018, FASB issued ASU No. 2018- 10, Codification Improvements to Topic 842, Leases, ("ASU No. 2018-10") to further clarify,

correct and consolidate various areas previously discussed in ASU 2016-02. FASB also issued ASU No. 2018- 11, Leases: Targeted Improvements ("ASU 2018-11") to provide entities another option for transition and lessors with a practical expedient. The transition option allows entities to not apply ASU No. 2016-02 in comparative periods in the financial statements in the year of adoption. The amendments in ASU No. 2016-02, ASU No. 2018-10 and ASU No. 2018-11 are effective for fiscal years beginning after December 15, 2021 for non-public entities and interim periods within fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. For non-public entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. Certain amendments included in the update allows for a retrospective, modified retrospective, or prospective method of adoption. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

Reference Rate Reform

In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU No. 2020-04”). The amendment in this update provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment in this update applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendment does not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendment in this update is effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted this amendment on March 12, 2020. There was no impact to the Consolidated Financial Statements for the year ended December 31, 2020. The Company continues to monitor the transition of LIBOR to alternative reference rate measures.

1. Description of Business

DoubleVerify Holdings, Inc. (the “Company”) is a software platform for digital media measurement, data and analytics. The Company’s solutions provide advertisers with a single measure of digital ad quality and effectiveness, the Authentic Ad, which ensures that a digital ad was delivered in a brand-safe environment, fully viewable, by a real person and in the intended geography. The Company’s software interface, Pinnacle, provides customers with access to data on all of their digital ads and enables them to make changes to their ad strategies on a real-time basis. The Company’s software solutions are integrated across the entire digital advertising ecosystem, including programmatic platforms, social media channels and digital publishers. The Company’s solutions are accredited by the Media Rating Council, which allows the Company’s data to be used as a single-source standard in the evaluation and measurement of digital ads.

The Company was incorporated on August 16, 2017, is registered in the state of Delaware and is the parent company of DoubleVerify Midco, Inc. (“MidCo”), which is in turn the parent company of DoubleVerify Inc. (“DoubleVerify”). On August 18, 2017, DoubleVerify entered into an agreement and plan of merger (the “Agreement”), whereby the Company, formerly known as Pixel Group Holdings, Inc. (the “Ultimate Parent”) and Pixel Merger Sub, Inc. (“Merger Sub”), a wholly-owned subsidiary of the Company, agreed to provide for the merger of the Merger Sub with DoubleVerify pursuant to the terms and conditions of the Agreement.

On the effective date, Merger Sub was merged with and into DoubleVerify whereupon the separate corporate existence of Merger Sub ceased and DoubleVerify continued as the surviving corporation.

Through the merger, the Company acquired 100% of the outstanding equity instruments of DoubleVerify (the “Acquisition”) resulting in a change of control at the parent level. The merger resulted in the application of acquisition accounting under the provisions of Financial Accounting Standards Board (“FASB”) Topic Accounting Standards Codification (“ASC”) 805, “Business Combinations.”

The Company has wholly-owned subsidiaries in numerous jurisdictions including Israel, the United Kingdom, Germany, Singapore, Australia, Canada, Brazil, Belgium, Mexico, France, Japan, Spain, and Finland, and operates in one reportable segment.

Since January 2020, an outbreak of the 2019 novel coronavirus (“COVID-19”) has evolved into a worldwide pandemic. The Company has modified operations in line with business continuity plans. As a result of the pandemic, the Company has temporarily closed offices globally, including the corporate headquarters in New York, and is operating with nearly all staff working remotely. The pandemic has resulted in market disruptions and a global economic slowdown, which has materially impacted demand for a broad variety of goods and services, and is also disrupting sales channels and marketing activities. The duration of such disruptions is highly uncertain and cannot be predicted. While COVID-19 has not had a significant impact on the Company’s results from operations to date, to the extent that demand for digital advertising declines, the Company’s results and financial condition may be materially and adversely impacted.

2.     Basis of Presentation and Summary of Significant Accounting Policies

Basis of Preparation and Principles of Consolidation

The accompanying Condensed Consolidated Balance Sheets as of September 30, 2021 and December 31, 2020, the Condensed Consolidated Statements of Operations and Comprehensive Income for the three and nine months ended September 30, 2021 and 2020, the Condensed Consolidated Statements of Stockholders’ Equity for the three and nine months ended September 30, 2021 and 2020, and the Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2021 and 2020 reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair presentation of the results for the periods shown in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the applicable rules and regulations of the SEC for interim financial reporting periods. Accordingly, certain information and footnote disclosures have been condensed or omitted pursuant to SEC rules that would ordinarily be required under GAAP for complete financial statements. These unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements as of December 31, 2020 and 2019 and for the years then ended and the accompanying notes thereto included in the Company’s Prospectus.

On March 29, 2021, the Company effected a 1-for-3 reverse stock split (‘‘reverse stock split’’) of its outstanding common stock, par value $0.001 per share (“common stock”), and a proportional adjustment to the existing conversion ratio of its then-outstanding Series A Preferred Stock, par value $0.01 per share (“preferred stock”). Accordingly, all share and per share amounts for all periods presented in these Condensed Consolidated Financial Statements and notes thereto, have been adjusted retrospectively, where applicable, to reflect this reverse stock split.

Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and measurement of items including, but not limited to: revenue recognition criteria including the determination of principal versus agent revenue considerations, income taxes, the valuation and recoverability of goodwill and intangible assets, the assessment of potential loss from contingencies, the allowance for doubtful accounts, and assumptions used in determining the fair value of stock-based compensation. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. These estimates are based on the information available as of the date of the Condensed Consolidated Financial Statements.

Recently Issued Accounting Pronouncements

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with certain new or revised accounting standards.

Financial Instruments - Credit Losses

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), 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 accounts receivable. This guidance is effective for annual reporting periods beginning after December 15, 2022 for non-public entities, including interim periods within that reporting period. Early adoption is permitted and the update allows for a modified retrospective method of adoption. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Cloud Computing

In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2020 for non-public entities, and interim periods within annual periods beginning after December 15, 2021. The update allows for a retrospective or prospective method of adoption.

The Company intends to adopt amendment ASU No. 2018-15 on December 31, 2021 using a prospective approach. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases Topic 842 (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. In July 2018, FASB issued ASU No. 2018- 10, Codification Improvements to Topic 842, Leases, ("ASU No. 2018-10") to further clarify,

correct and consolidate various areas previously discussed in ASU 2016-02. FASB also issued ASU No. 2018- 11, Leases: Targeted Improvements ("ASU 2018-11") to provide entities another option for transition and lessors with a practical expedient. The transition option allows entities to not apply ASU No. 2016-02 in comparative periods in the financial statements in the year of adoption. The amendments in ASU No. 2016-02, ASU No. 2018-10 and ASU No. 2018-11 are effective for fiscal years beginning after December 15, 2021 for non-public entities and interim periods within fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. For non-public entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. Certain amendments included in the update allows for a retrospective, modified retrospective, or prospective method of adoption. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Preparation and Principles of Consolidation

The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and reflect the financial statements of the Company and all of its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

On March 29, 2021, the Company effected a 1-for-3 reverse stock split (“reverse stock split”) of its outstanding common stock and a proportional adjustment to the existing conversion ratio for the preferred stock described in Footnote 13, Stockholders’ Equity.

Accordingly, all share and per share amounts for all periods presented in these consolidated financial statements and notes thereto, have been adjusted retrospectively, where applicable, to reflect this reverse stock split.

Use of Estimates and Judgments in the Preparation of the Consolidated Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and measurement of items including, but not limited to: revenue recognition criteria including the determination of principal versus agent revenue considerations, income taxes, the valuation and recoverability of goodwill and intangible assets, the assessment of potential loss from contingencies, assumptions in valuing acquired assets and liabilities assumed in business combinations, the allowance for doubtful accounts, and assumptions used in determining the fair value of stock-based compensation. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates. These estimates are based on the information available as of the date of the Consolidated Financial Statements.

Segment Reporting

The Company’s operating segments are determined based on the units that constitute a business for which discrete financial information is available and for which operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”). The CODM is the highest level of management responsible for assessing the Company’s overall performance and making operational decisions. The Company operates in one single operating and reportable segment.

Fair Value Measurements

The Company evaluates the fair value of certain assets and liabilities using the fair value hierarchy. Fair value is an exit price representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company applies the three-tier GAAP value hierarchy which prioritizes the inputs used in measuring fair value as follows:

Level 1 — observable inputs such as quoted prices in active markets;

Level 2 — inputs other than the quoted prices in active markets that are observable either directly or indirectly;

Level 3 — unobservable inputs of which there is little or no market data, which require the Company to develop its own assumptions.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measure.

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.

Foreign Currency

A majority of the Company’s revenues are generated in U.S. dollars. In addition, most of the Company’s costs are denominated and determined in U.S. dollars. Thus, the reporting currency of the Company is the U.S. dollar.

The functional currency of the Company’s foreign subsidiaries is generally the local currency. The assets and liabilities of subsidiaries whose functional currency is a foreign currency are translated at the period-end exchange rates. Income statement items are translated at the average monthly rates for the year. The resulting translation adjustment is recorded as a component of accumulated other comprehensive (income) loss and is included in the Consolidated Statement of Stockholders’ Equity.

For the years ended December 31, 2020, 2019, and 2018, the Company recorded an aggregate transaction loss of $0.5 million, an aggregate transaction gain of less than $0.1 million, and an aggregate transaction loss of $0.5 million, respectively. The aggregate transaction gains or losses were recorded in the Consolidated Statement of Operations and Comprehensive Income.

Cash and Cash Equivalents

The Company considers all short-term highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. Pursuant to the Company’s investment policy, its surplus funds are kept as cash or cash equivalents in money market and savings accounts to reduce its exposure to market risk.

Trade Receivables Net of Allowances for Doubtful Accounts

Trade receivables are non-interest bearing and are stated at gross invoice amounts. A receivable is recorded when the Company has an unconditional right to receive payment based on the satisfaction of performance obligations, such that only the passage of time is required before consideration is due, regardless of whether amounts are billed or unbilled. Included in trade receivables on the Consolidated Balance Sheets are unbilled receivable balances which have not yet been invoiced.

The Company estimates its allowance for doubtful accounts by evaluating specific accounts where information indicates the customers may have an inability to meet financial obligations, such as bankruptcy proceedings and receivable amounts outstanding for an extended period beyond contractual terms. In these cases, the Company uses assumptions and judgment, based on the best available facts and circumstances, to either record a specific allowance against these customer balances or to write the balances off.

Write-offs of accounts receivable are taken in the period when the Company has exhausted its efforts to collect overdue and unpaid receivables or otherwise has evaluated other circumstances that indicate that the Company should abandon such efforts.

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets on the Consolidated Balance Sheets consistent primarily of prepaid taxes, other general prepaid expenses, restricted cash, and value added tax assets. Any expenses paid prior to the related services being rendered are recorded as prepaid expenses and amortized over the period of service.

Restricted cash represents amounts pledged as collateral for certain agreements with third parties. Upon satisfying the terms of the agreements, the funds are expected to be released and available for use by the Company. As of December 31, 2020 and 2019, the Company had less than $0.1 million and $0.4 million of restricted cash, respectively.

As of December 31, 2020 and 2019, the Company had prepaid income taxes of $10.4 million and $0.9 million, respectively.

Property, Plant and Equipment, Net

Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the following estimated useful lives of the assets:

Computer equipment	3 years
Office furniture and equipment	4 ‑ 7 years
Leasehold improvements	4 ‑ 6 years

Assets under capital leases are recorded at their net present value at the inception of the lease. Assets under capital leases and leasehold improvements are amortized over the shorter of the related lease terms or their useful lives.

Expenditures which significantly improve or extend the life of an asset are capitalized, while charges for routine maintenance and repairs are expensed during the year incurred.

Capitalized Software

Capitalized software, which is included in Property, plant and equipment, net, consists of costs to purchase and develop internal-use software, which the Company uses to provide services to its customers. The costs to purchase and develop internal-use software are capitalized from the time that the preliminary project stage is completed, and it is considered probable that the software will be used to perform the function intended. These costs include personnel and related employee benefits for employees directly associated with the software development and external costs of the materials or services consumed in developing or obtaining the software. Any costs incurred during subsequent efforts to upgrade and enhance the functionality of the software are also capitalized. Once this software is ready for use in the Company’s products, these costs are amortized on a straight-line basis over the estimated useful life of the software, which is 3 years. During the years ended December 31, 2020 and December 31, 2019, the Company capitalized $5.2 million and $3.1 million in internal-use software cost, respectively. Amortization expense was $1.4 million and $0.4 million on capitalized internal-use software costs during the years ended December 31, 2020 and December 31, 2019, respectively. This is included within depreciation expense on Property, plant and equipment, net. The Company did not capitalize software costs and recognize amortization expense in 2018 as the Company did not have a process in place to track costs.

Leases

The Company leases its facilities and meets the requirements to account for these leases as operating leases. For facility leases that contain rent escalations or rent concession provisions, the Company records its lease expense during the lease term on a straight-line basis over the term of the lease. The Company records the difference between the rent paid and the straight-line rent as a deferred rent liability. Leasehold improvements funded by landlords or allowances are recorded as leasehold improvement assets and a deferred rent liability which is amortized as a reduction of rent expense over the lesser of the term of the lease or life of the asset.

The Company leases computer equipment that meet the requirements to account for these as capital leases. The Company records capital leases as an asset and an obligation at an amount equal to the present value of the minimum lease payments as determined at the beginning of the lease term. Depreciation of capitalized leased assets is computed over their useful life and is included in depreciation expense.

Business Combinations

The Company recognizes assets acquired and liabilities assumed at their fair value on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill. Acquisition-related costs are expensed as incurred.

Goodwill

Goodwill represents the excess of purchase price over the fair value of tangible net assets and identifiable intangible assets of the businesses acquired.

The valuation of goodwill involves the use of management’s estimates and assumptions. The carrying value of goodwill is not amortized, but rather, is evaluated for impairment at least annually, as of October 1, and, additionally on an interim basis, whenever events or changes in circumstances indicate that the carrying amount of goodwill will not be recoverable. The Company performs this evaluation by comparing the fair value of a reporting unit to its carrying value, including goodwill recorded by the reporting unit.

The Company has a single reporting unit. The Company’s review for impairment includes an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs a quantitative goodwill impairment test, which compares the fair value of the reporting unit with its carrying amounts. The Company estimates the fair value of its reporting unit considering both income and market-based approaches. The estimated fair value of a reporting unit is determined based on assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values.

The Company completed its analyses for each of the years ended December 31, 2020, 2019, and 2018 and determined that there was no impairment of goodwill.

Intangible Assets, Net

Intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives.

The estimated useful lives of the Company’s finite-lived intangible assets are as follows:

Technology	4 ‑ 8 years
Customer relationships	5 ‑ 12 years
Trademarks	5 ‑ 15 years

Impairment of Long-Lived Assets

Long-lived assets, such as property and equipment and intangible assets subject to depreciation and amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable or that the useful life is shorter than the Company had originally estimated. Recoverability of these assets is measured by comparison of the carrying amount of each asset or asset group to the future undiscounted cash flows the asset or asset group is expected to generate over their remaining lives. If the asset or asset group is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset or asset group. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the new shorter useful life. There were no impairments recognized for the years ended December 31, 2020, 2019 and 2018.

Debt Issuance Costs

Prior to the Company’s New Revolving Credit Facility, as described in Footnote 8, Long-term Debt, the Company reflected debt issuance costs for the Prior Credit Facilities in the Consolidated Balance Sheets as a direct deduction from the gross amount, consistent with the presentation of a debt discount. Debt issuance costs for the Prior Credit Facilities were amortized to interest expense over the term of the underlying debt instrument, utilizing the effective interest rate method. For the New Revolving Credit Facility, debt issuance costs meet the definition of an asset and are recorded in the Consolidated Balances Sheets in Other Non-Current Assets. Debt issuance costs incurred for the New Revolving Credit Facility that were capitalized total $0.9 million. Debt issuance costs for the New Revolving Credit Facility are amortized to interest expense over the contractual term of the underlying debt instrument on a straight-line basis through the maturity date of the instrument of October 1, 2025. As of December 31, 2020 and December 31, 2019, remaining debt issuance costs were $1.4 million and $0.9 million, respectively.

Revenue Recognition

On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (ASC 606), using the modified retrospective method. The adoption of ASU 2014-09 did not result in a material change in the timing or amount of revenue recognized. Prior to January 1, 2019, the Company recognized its revenues in accordance with ASC 605, Revenue Recognition, when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectability is probable. Results for reporting periods beginning after January 1, 2019 are presented in accordance with ASC 606, while prior period amounts have not been adjusted.

In accordance with ASC 606, the Company recognizes revenue under the core principle to depict the transfer of control to its customers in an amount reflecting the consideration to which it expected to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

The Company’s contracts with customers may include multiple promised services, consisting of the various impression measurement services the Company offers. For all revenue channels, the Company identifies performance obligations by evaluating whether the promised goods and services are capable of being distinct and distinct within the context of the contract at contract inception. Promised goods and services that are not distinct at contract inception are combined as one performance obligation. Once the Company identifies the performance obligations, the Company will determine the transaction price based on contractually fixed amounts. The Company allocates the transaction price to each performance obligation based on the standalone selling price.

The major sources of revenue include Advertiser Direct, Advertiser Programmatic, and Supply-Side Customers.

Advertiser Direct and Advertiser Programmatic Revenue

For Advertiser Direct revenue, advertisers can purchase the Company’s services to measure the quality and performance of ads purchased directly from digital properties, including publishers and social media platforms. Advertisers are provided access to the Company’s platform through the Company’s proprietary self-service software that provides the Company’s customers with access to data on all their digital ads and enables them to make changes to their ad strategies. In these arrangements, the customer pays a fee to the Company based on the ads measured.

For Advertiser Programmatic revenues, advertisers purchase the Company’s services through programmatic platforms to evaluate the quality of ad inventories before they are purchased. Advertisers may purchase the Company’s service offering through a Demand-Side Platform that manages various ad campaign auctions and inventory on behalf of the advertisers. Customers elect to use the Company’s service of evaluating the quality of advertising inventory up for bid on an advertising exchange. The ability to provide these services to customers requires that the Company enter into product integration agreements with Demand-Side Platforms who in turn make the Company’s services available to advertisers. In these arrangements, the customer pays a fee to the Company (collected by the Demand-Side Platform) for the successful execution of the purchase of advertising inventory on an exchange.

For Advertiser Direct and Advertiser Programmatic revenues, contracts with multiple performance obligations typically consist of services aimed at advertisers to help evaluate and ensure the success of a brand campaign by measuring authentic impressions. These services are generally delivered together as impressions are measured. Revenue is recognized over time, as the Company is providing services that the customer is continuously consuming and receiving benefit from or upon completion of the service. The Company considers the “right to invoice” practical expedient appropriate in the context of the Company’s contracts as this directly corresponds to the value of the Company’s performance to date. In this case, the Company’s pricing structure is (1) solely variable on the basis of the customer’s usage of the Company’s services, (2) is priced at a fixed rate per usage and (3) gives the entity the right to invoice the customer for its usage as it occurs.

Supply-Side Customers

Supply-Side Customer revenues consist of arrangements with publishers and other supply-side customers to provide them with software solutions and data analytics to enable them to maximize revenue from their digital advertising inventory. Certain arrangements include minimum guaranteed fees that reset monthly and are recognized on a straight-line basis over the access period, which is usually twelve months. For contracts that contain overages, once the minimum guaranteed amount is achieved, overages are recognized as earned over time based on a tiered pricing structure. Such revenues are recognized on an input method time-elapsed basis, as the Company is providing services that the customer is continuously consuming and receiving benefit from, and such recognition best depicts the transfer of control to the customer. Overages give rise to variable consideration that is allocated to the distinct periods to which the overage relates.

Transactions that Involve Third Parties

For transactions that involve third parties, the Company evaluates which party in the arrangement obtains control of the Company’s services (and is therefore the Company’s customer), which impacts whether the Company reports as revenue the gross amounts paid by the advertiser through the Demand-Side Platform or the net amount paid by the Company’s Demand-Side Platform partners. For certain arrangements, advertisers (“customers”) may purchase the Company’s service offering through a Demand-Side Platform that manages various ad campaign auctions and inventory on behalf of the advertisers. Customers elect to use the Company’s service of evaluating the quality of advertising inventory up for bid on an advertising exchange. The ability to provide these services to customers requires that the Company enter into product integration agreements with Demand-Side Platforms who in turn make the Company’s services available to advertisers. In these arrangements, the customer pays a fee to the Company (collected by the Demand-Side Platform) for the successful execution of the purchase of advertising inventory on an exchange. In these transactions, the Company transfers control of the Company’s services directly to the advertiser (who is the Company’s customer) and therefore revenue is recognized for the gross amount paid by the advertiser for the Company’s services. Specifically, the Company transfers control of the data that is influencing the purchasing decisions directly to the customer and the Company is primarily responsible for providing these services to the customer. That is, control of these services (or a right to these services) does not transfer to the Demand-Side Platform before they are transferred to the Company’s customers. Further, the Company has latitude in establishing the

sales price with those customers as there is a fixed retail rate card that is included in the product integration agreements with the Demand-Side Platforms or are governed by contracts in place with the customers. Accordingly, the Company records revenue for the gross amounts paid by advertisers for these services and records the amounts retained by the Demand-Side Platforms as a cost of revenue.

Contract assets relate to the Company’s conditional right to consideration for completed performance under the contract (e.g., unbilled receivables) and are included in Trade receivables, net of allowance for doubtful accounts.

Costs to Fulfill or Obtain a Contract

The Company recognizes direct fulfillment costs as an expense when incurred. These costs include commission programs to compensate employees for generating sales orders under the Company’s master services agreements or integration agreements, and are included in Sales, marketing, and customer support. The Company has not incurred incremental costs to obtain contracts during the periods ended December 31, 2020, 2019 and 2018, respectively.

Operating Expenses

Cost of revenue includes platform hosting fees, data center costs, software and other technology expenses and other costs directly associated with data infrastructure. Cost of revenue also includes personnel costs including salaries, bonuses, stock-based compensation, employee benefit costs, commissions related to revenue share arrangements with Demand-Side Platforms, and allocated overhead expenses for personnel who provide the Company’s customers with support in implementing and using the Company’s software platform. Cost of revenues excludes depreciation and amortization.

Product development expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs, and allocated overhead expenses inclusive of engineering, product and technical operation expenses, third-party consultant costs associated with the ongoing research, development and maintenance of the Company’s software platform. 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 and included in Property, plant and equipment, net on the Company’s Consolidated Balance Sheets.

Sales, marketing and customer support expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs, commission costs, and allocated overhead expenses for the Company’s sales, marketing and customer support personnel. Sales, marketing, and customer support expense also include costs for market development programs, advertising costs, attendance at events and trade shows, promotional and other marketing activities. Advertising costs include expenses associated with direct marketing but exclude the costs of attendance at events and trade shows. Advertising costs were less than $0.1 million, $0.1 million, and nil for the years ended December 31, 2020, 2019 and 2018, respectively. Commissions costs are expensed as incurred.

General and administrative expenses consist primarily of personnel costs, including salaries, bonuses, stock-based compensation, employee benefits costs and other overhead expenses associated with the Company’s executive, finance, legal, human resources, compliance, and other administrative personnel, as well as accounting, tax, and legal professional services fees, rent, bad debt expense and other overhead expense related to human resource and finance activities, as well as other corporate costs including offering costs.

For the year ended December 31, 2020, the Company recorded $0.9 million in recoveries from business interruption insurance classified in General and administrative in the Consolidated Statement of Operations and Comprehensive Income. The insurance recovery related to investigating and remediating certain information technology and cybersecurity matters that occurred in the year. There were no recoveries from business interruption insurance for the years ended December 31, 2019 and 2018, respectively.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and trade receivables. The Company maintains cash deposits with financial institutions that, from time to time, exceed applicable insurance limits. The Company reduces this risk by maintaining such deposits with high quality financial institutions that management believes are creditworthy. Cash and cash equivalents are maintained with several financial institutions domestically and

internationally. The combined account balances held on deposit at each institution typically exceed Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company monitors this credit risk and makes adjustments to the concentrations as necessary. As of December 31, 2020 and 2019, the Company had deposits of $29.0 million and $7.5 million, respectively, which exceeded the FDIC insurance coverage amounts.

With respect to accounts receivable, credit risk is mitigated by the Company’s ongoing credit evaluation of its customers’ financial condition. No single customer accounted for more than 10 percent of trade receivables for the years ended December 31, 2020 and 2019. With respect to revenues, no single customer accounted for more than 10% of revenues for the years ended December 31, 2020, 2019 and 2018.

Other (Income) Expense, Net

Other (income) expense, net primarily consists of interest income, change in fair value associated with contingent considerations, loss on extinguishment of debt, and the impact of foreign currency transaction gains and losses associated with monetary assets and liabilities.

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes are provided for temporary differences in recognizing certain income, expense and credit items for financial reporting purposes and tax reporting purposes. Such deferred income taxes primarily relate to the difference between the tax bases of assets and liabilities and their financial reporting amounts. Deferred tax assets and liabilities are measured by applying enacted statutory tax rates applicable to the future years in which deferred tax assets or liabilities are expected to be settled or realized. Excess tax benefits and tax deficiencies are recognized in the income tax provision in the period in which they occur.

The Company records a valuation allowance when it determines, based on available positive and negative evidence, that it is more-likely-than-not that some portion or all of its deferred tax assets will not be realized. The Company determines the realizability of its deferred tax assets primarily based on the reversal of existing taxable temporary differences and projections of future taxable income (exclusive of reversing temporary differences and carryforwards). In evaluating such projections, the Company considers its history of profitability, the competitive environment, and general economic conditions. In addition, the Company considers the time frame over which it would take to utilize the deferred tax assets prior to their expiration.

For certain tax positions, the Company uses a more-likely-than-not threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured at the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense.

On December 22, 2017, U.S. tax reform legislation known as the Tax Cuts and Jobs Act (the “TCJA”) was signed into law. As of December 31, 2018, the Company’s accounting for the TCJA has been completed. The Company has determined the effects of certain provisions, including but not limited to: a reduction in the corporate tax rate from 35% to 21%, a limitation of the deductibility of certain officers’ compensation, a limitation on the current deductibility of net interest expense in excess of 30% of adjusted taxable income, a limitation of net operating losses generated after 2018 to 80% of taxable income, an incremental tax (base erosion anti-abuse or “BEAT”) on excessive amounts paid to foreign related parties, and a minimum tax on certain foreign earnings in excess of 10% of the foreign subsidiaries tangible assets (global intangible low- taxed income or “GILTI”). As part of its GILTI review, the Company has determined that it will account for GILTI income as it is generated (i.e., treat it as a period expense).

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (SEC Update). The update was issued to provide guidance on the income tax accounting implications of the TCJA. This includes the filing of financial statements with provisional amounts if companies are unable to finalize accounting provisions due to the changes enacted by the TCJA. In addition, subsequent changes to provisional amounts and disclosures are addressed in the ASU. The Company has completed the accounting for the effects of the Tax Act in its Consolidated Financial Statements with immaterial adjustments recorded as of December 31, 2018.

The COVID-19 pandemic has a global reach, and many countries are introducing measures that provide relief to taxpayers in a variety of ways. In March 2020, the U.S. government enacted tax legislation containing provisions to support businesses during the COVID-19 pandemic (the “CARES Act”), including deferment of the employer portion of certain payroll taxes, refundable payroll tax credits, and technical amendments to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s income tax provision for the year ended December 31, 2020.

Stock-Based Compensation

The Company accounts for stock-based compensation awards issued to its employees and members of its Board of Directors (the “Board”) in accordance with ASC 718, Compensation — Stock Compensation. ASC 718 requires that the cost resulting from all share-based payment transactions be recognized in the financial statements. This statement establishes fair value as the measurement objective in accounting for share-based payment arrangements and requires all entities to apply a fair value-based measurement method in accounting for these transactions with employees.

Stock-based compensation is measured at grant date based on the estimated fair value of the award and is expensed on a straight-line basis over the requisite service period net of an estimated forfeiture rate. The Company uses historical data to estimate forfeitures. The Company’s stock-based compensation awards relate to restricted stock units and stock options. The fair value of restricted stock unit awards is determined on the grant date based on the grant date stock price or a Monte Carlo Simulation model in instances where a market condition exists. For share-based awards that vest subject to the satisfaction of a market condition, the fair value measurement date for stock-based compensation is the date of the grant and the expense is recognized using the accelerated attribution method over the derived service period or upon achievement of the market condition. The fair value of stock option awards is determined on the grant date using the Black-Scholes Merton option pricing model. The option-pricing model requires a number of assumptions, of which the most significant are the expected stock price volatility, the expected option term and the fair market value of the Company’s common stock. Since there is no public market for the Company’s common stock, the Company bases its estimates of expected volatility on the median historical volatility of a group of publicly traded companies it believes are comparable to the Company, and uses the average of i) the weighted average vesting period and ii) the contractual life of the option, calculated using the “simplified method”. The simplified method allows for estimating the expected life based on an average of the option vesting term and option life, provided that all options meet certain criteria of “plain vanilla” options. The risk-free interest rate is based on the yield from U.S. treasury bonds as of the expected term. Additionally, the Company has assumed that dividends will not be paid.

Certain grants of stock options to executives contain certain vesting conditions, whereby, subject to the option holders continued employment with the Company, the award will vest upon the date the Company’s majority owner has received cumulative cash proceeds in respect of its investment in the Company equal to two times its aggregate cash investment in the Company. This is a market condition, but the requirement that the award vest on the basis of sufficient proceeds distributed to the Company’s majority owner represents a performance condition. During the years ended December 31, 2020, 2019 and 2018, the outcome of that performance condition is not considered probable, and therefore the Company did not recognize any expense associated with these stock options.

A certain grant of restricted stock units to an executive contains certain vesting conditions, whereby, subject to the award holders continued employment with the Company, the award will vest upon the date the Company’s achieves a certain fair market value for its common stock share price. The estimated fair value of the award was determined using a Monte Carlo Simulation model in accordance with ASC 718. During the year ended December 31, 2020, the market condition was satisfied; therefore, the Company recognized stock-based compensation expense of $0.7 million associated with these restricted stock units in General and administrative expense in the Consolidated Statements of Operations and Comprehensive Income.

Earnings Per Share

Basic and diluted earnings per share (“EPS”) are determined in accordance with ASC 260, Earnings per Share. Basic EPS is calculated by dividing net income by the weighted average number of common stock outstanding during the period. Diluted EPS is based upon the weighted average number of outstanding shares of common stock and dilutive common stock equivalents in the period. Common stock equivalents arise from dilutive stock options and restricted stock units and are computed using the treasury stock method. Anti-dilutive common stock equivalents are excluded from diluted EPS.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with certain new or revised accounting standards. As a result, the Company’s financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

These exemptions will apply until the Company no longer meets the requirement of being an emerging growth company. The Company will remain an emerging growth company until the earlier of (a) the last day of the fiscal year (i) following the fifth anniversary of the completion of this offering, (ii) in which the Company has total annual gross revenue of at least $1.07 billion or (iii) in which the Company is deemed to be a large accelerated filer, which means the market value of the Company’s common stock that is held by non-affiliates exceeds $700.0 million as of the last business day of the Company’s prior second fiscal quarter, and (b) the date on which the Company has issued more than $1.07 billion in non-convertible debt during the prior three-year period.

Offering Costs

Offering costs consist of expenses incurred during the Company’s preparation of its proposed initial public offering (“IPO”). These expenses include registration fees, filing fees, specific legal and accounting fees which are directly related to the Company’s efforts to raise capital through an IPO. The Company expenses offering costs as they are incurred. For the year ended December 31, 2020, offering costs were $3.6 million and recorded in General and administrative in the Consolidated Statement of Operations and Comprehensive Income.

Recently Issued Accounting Pronouncements

Financial Instruments — Credit Losses

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), 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 accounts receivable. This guidance is effective for annual reporting periods beginning after December 15, 2022 for non-public entities, including interim periods within that reporting period. Early adoption is permitted. The Company is currently in process of evaluating the impact of this standard on the Company’s Consolidated Financial Statements.

Cloud Computing

In August 2018, the FASB issued ASU No. 2018-15, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2020 for non-public entities, including interim reporting periods within those annual periods. The Company is currently in process of evaluating the impact of this standard on the Company’s Consolidated Financial Statements.

Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases Topic 842 (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. ASU 2016-02 is effective for fiscal years beginning after December 15, 2021 for non-public entities, with early adoption permitted. The Company is currently in process of evaluating the impact of this standard on the Company’s Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. This guidance is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements.

Reference Rate Reform

In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU No. 2020-04”). The amendment in this update provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment in this update applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendment does not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendment in this update is effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted this amendment on March 12, 2020. There was no impact to the Consolidated Financial Statements for the year ended December 31, 2020. The Company continues to monitor the transition of LIBOR to alternative reference rate measures.

Zentrick NV

On February 15, 2019, the Company acquired all of the outstanding stock of Zentrick NV (“Zentrick”). Zentrick, headquartered in Ghent, Belgium is a digital video technology company that provides middleware solutions that increase the performance of online video advertising for brand advertisers, advertising platforms and publishers. This acquisition integrates technology into The Company’s suite of products related to advertising viewability specifically on video formats, a growing segment of the advertising market and critical for the delivery of verification services to social platform and connected TV. The aggregate purchase price consists of 1) $23.2 million paid in cash in closing, which excluded closing adjustments of approximately $0.2 million paid in April 2019 2) $0.1 million in holdback payment of which 50% was payable 12 months after the closing date, and the remaining 50% payable 24 months after the closing date 3) up to $17.3 million of performance-based deferred payments comprised of two components. The first component has a $4.0 million maximum payment related to four milestone tranches of $1.0 million each based on achievement of certain product milestones (“technical milestones”). The second component has a total maximum payment of $13.0 million and varies based upon certain revenue targets in fiscal 2019, 2020, and 2021 (“revenue targets”).

Under the terms of the deferred payment, approximately $2.4 million of the technical milestones and $5.6 million of the revenue targets is accounted for as consideration in the business combination, and approximately $1.6 million of the technical milestones and $7.4 million of the revenue targets is compensation expense under ASC 710.

For the year ended December 31, 2019, $1.1 million of unrealized gains were charged to the Statement of Operations and Comprehensive Income. This decrease in fair value is due to actual 2020 revenues falling below the milestone target, a decrease in forecasted 2021 revenues for the 2021 revenue target, and changes in estimates related to the timing of achievement of two of the four technical milestones by approximately 6 months.

As of December 31, 2020, the technical milestone and revenue target components treated as compensation cost total $1.1 million, of which $0.8 million and $0.3 million and are included in Other Current Liabilities and Other Non-Current Liabilities, respectively, in the Consolidated Balance Sheets.

Leiki Oy

On December 27, 2018, the Company acquired all of the outstanding stock of Leiki Oy (“Leiki”). Leiki is headquartered in Helsinki, Finland and provides contact and contextual classification services in multiple languages for digital text and video data to brands and publishers worldwide. This acquisition expands contextual targeting into programmatic segments and provides content classification to publishers for greater optimization. The aggregate purchase price consists of 1) $13.1 million paid in closing in cash 2) working capital adjustment to be paid within 1 year, and 3) holdback payment of approximately $4.1 million of which 50% is payable 12 months after the closing date, and the remaining 50% payable 18 months after the closing date. Upon acquisition, the Company used $0.6 million in cash to pay down Leiki’s vested stock options, which was included in the consideration transferred.

The total consideration transferred was $17.8 million. The cash consideration transferred was $13.9 million, including closing adjustments of $0.2 million that was paid in 2019. The holdback payment is not contingent on a future event occurring or condition being met but based solely on the passage of time, therefore the holdback payment is not accounted for as a contingent consideration. The holdback payment is initially measured at fair value on the acquisition date and the deferred payment is included in the total cash consideration transferred. During the year ended December 31, 2019, the company paid $2.0 million, and therefore the deferred payment balance was $2.0 million and $3.9 million as of December 31, 2019 and 2018, respectively, which is presented in liabilities in the Consolidated Balance Sheets. The remaining deferred payment of $2.0 million was fully paid during the year ended December 31, 2020.

Cash equivalents consisting of money market funds of $11.7 million and money market funds and time deposits of $2.5 million as of September 30, 2021 and December 31, 2020, respectively, were classified as Level 1 of the fair value hierarchy and valued using quoted market prices in active markets.

Contingent consideration relates to potential payments that the Company may be required to make associated with a business combination. To the extent that the valuations of these liabilities are based on inputs that are less observable or not observable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is greatest for measures categorized in Level 3.

Rollforward of the fair value measurements of the contingent consideration categorized with Level 3 inputs as of September 30, 2021 is as follows:

Balance at January 1, 2021	$	1,660
Fair value adjustments		57
Payments during the year		—
Balance at September 30, 2021	$	1,717

The fair value of the component of contingent consideration related to achievement of revenue targets have been estimated using a Monte Carlo model to simulate future performance of the acquired business under a risk-neutral framework; significant assumptions include a risk-adjusted discount rate of 13.5% and revenue volatility of 29.0%. The fair value of the component of contingent consideration related to achievement of four technical milestones have been estimated using situation-based modeling, which considers the probability-weighted present value of the expected payout amount.

On October 1, 2020, DoubleVerify Inc., as borrower (the “Borrower”), and MidCo, as guarantor, entered into an amendment and restatement agreement with the banks and other financial institutions party thereto, as lenders, and Capital One, National Association, as administrative agent, letter of credit issuer and swing lender, and others, to (i) amend and restate the Prior Credit Agreement as defined in the Prospectus (the Prior Credit Agreement, as amended and restated on October 1, 2020, the “Credit Agreement”) and (ii) replace the Prior Credit Facilities (as defined in the Prospectus) with a new senior secured revolving credit facility (the “New Revolving Credit Facility”) in an aggregate principal amount of $150.0 million (with a letter of credit facility of up to $15.0 million as a sublimit). Subject to certain terms and conditions, the Borrower is entitled to request additional term loan facilities or increases in the revolving credit commitments under the New Revolving Credit Facility. The New Revolving Credit Facility is payable in quarterly installments for interest, with the principal balance due in full at maturity on October 1, 2025. Additional fees paid quarterly include fees for the unused revolving facility and unused letter of credit. The commitment fee on any unused balance is payable periodically and may range from 0.25% to 0.40% based upon the total net leverage ratio. The New Revolving Credit Facility bears interest at LIBOR plus 2.25%, which may vary from time to time based on the Borrower’s total net leverage ratio calculated in accordance with the Credit Agreement.

The New Revolving Credit Facility contains a number of significant negative covenants. Subject to certain exceptions, these covenants require the Borrower to comply with certain requirements and restrictions to, among other things: incur indebtedness; create liens; engage in mergers or consolidations; make investments, loans and advances; pay dividends or other distributions and repurchase capital stock; sell assets; engage in certain transactions with affiliates; enter into sale and leaseback transactions; and make certain accounting changes. As a result of these restrictions, substantially all of the net assets of the Borrower are restricted from distribution to the Company or any of its holders of equity.

The New Revolving Credit Facility has a first priority lien on substantially all of the assets of MidCo, the Borrower and Ad-Juster, Inc., the Company’s indirect subsidiary. The New Revolving Credit Facility requires the Borrower to remain in compliance with a maximum total net leverage ratio and a minimum fixed charge coverage ratio as defined in the Credit Agreement.

As of September 30, 2021, the maximum total net leverage ratio and minimum fixed charge coverage ratio is 3.5x and 1.25x, respectively. The Borrower is in compliance with all covenants under the New Revolving Credit Facility as of September 30, 2021.

On April 30, 2021 the Company used a portion of the proceeds from the IPO and the concurrent private placement to pay the outstanding balance. As of September 30, 2021 and December 31, 2020, there was $0 outstanding and $22.0 million outstanding under the New Revolving Credit Facility, respectively.

On September 20, 2017, DoubleVerify, as borrower, and Midco, as guarantor, entered into a senior secured credit facility with Capital One, National Association consisting of a $30 million term loan facility, a revolving loan facility of up to $7 million (collectively, the “Old Credit Facilities”), and a letter of credit facility of up to $3 million as a sublimit of the revolving loan facility.

On July 31, 2018, DoubleVerify, as borrower, and Midco, as guarantor, entered into an amended and restated credit agreement (the “Prior Credit Agreement”) that amended and replaced the Old Credit Facilities, providing for a $55 million term loan facility with Capital One, National Association (the “Prior Term Loan”), a $20 million delayed draw term loan facility (the “Prior Delayed Draw Term Loan”), a revolving loan facility of up to $20 million (the “Prior Revolver” and, collectively with the Prior Term Loan and the Prior Delayed Draw Term Loan, the “Prior Credit Facilities”), and a letter of credit facility of up to $5 million as a sublimit of the Prior Revolver. The Prior Credit Facilities were used to refinance the Old Credit Facilities. The Prior Credit Facilities were payable in quarterly installments of $0.1 million, had an interest rate of LIBOR plus 3.75%, and were due in full at maturity on July 31, 2023.

On October 1, 2020, DoubleVerify, as borrower, and Midco, as guarantor, entered into an amendment and restatement agreement with the banks and other financial institutions party thereto, as lenders, and Capital One, National Association, as administrative agent, letter of credit issuer and swing lender, and others, to (i) amend and restate the Prior Credit Agreement (the Prior Credit Agreement, as amended and restated on October 1, 2020, the “Credit Agreement”) and (ii) replace the Prior Credit Facilities with a new senior secured revolving credit facility (the “New Revolving Credit Facility”) in an aggregate principal amount of $150.0 million (with a letter of credit facility of up to $15.0 million as a sublimit). Subject to certain terms and conditions, the Borrower is entitled to request additional term loan facilities or increases in the revolving credit commitments under the New Revolving Credit Facility. The New Revolving Credit Facility is payable in quarterly installments for interest, with the principal balance due in full at maturity on October 1, 2025. Additional fees paid quarterly include fees for the unused revolving facility and unused letter of credit. The commitment fee on any unused balance is payable periodically and may range from 0.25% to 0.40% based upon the total net leverage ratio. The New Revolving Credit Facility bears interest at LIBOR plus 2.25%, which may vary from time to time based on DoubleVerify’s total net leverage ratio calculated in accordance with the Credit Agreement.

In connection with the amended and restated agreement, the Company recorded a loss on extinguishment of $0.4 million in Interest expense (income) in the Consolidated Statements of Operations and Comprehensive Income.

The New Revolving Credit Facility contains a number of significant negative covenants. Subject to certain exceptions, these covenants require DoubleVerify to comply with certain requirements and restrictions to, among other things: incur indebtedness; create liens; engage in mergers or consolidations; make investments, loans and advances; pay dividends or other distributions and repurchase capital stock; sell assets; engage in certain transactions with affiliates; enter into sale and leaseback transactions; and make

certain accounting changes. As a result of these restrictions, substantially all of the net assets of DoubleVerify are restricted from distribution to the Company or any of its holders of equity.

The New Revolving Credit Facility has a first priority lien on substantially all of the assets of Midco, DoubleVerify and Ad-Juster, Inc., the Company’s indirect subsidiary. The New Revolving Credit Facility requires DoubleVerify to remain in compliance with a maximum total net leverage ratio and a minimum fixed charge coverage ratio as defined in the Credit Agreement.

Maximum total net leverage ratio is measured as consolidated total net indebtedness divided by consolidated adjusted earnings before interest, taxes, depreciation and amortization for the most recently ended twelve-month period for which financial statement have been delivered, as defined by the Credit Agreement.

Minimum fixed charge coverage ratio is measured as the ratio of consolidated adjusted earnings before interest, taxes, depreciation, and amortization for the most recently ended twelve-month period for which financial statements have been delivered less the sum of consolidated capital expenditures, taxes, management fees, and restricted payments to consolidated interest expense for such period plus schedule principal payments of indebtedness, as defined by the Credit Agreement.

As of December 31, 2020, the maximum total net leverage ratio and minimum fixed charge coverage ratio is 3.5x and 1.25x, respectively. DoubleVerify is in compliance with all covenants under the New Revolving Credit Facility as of December 31, 2020.

DoubleVerify drew $90.0 million on the New Revolving Credit Facility at the close of the transaction to pay off the Prior Credit Facilities balance of $73.6 million as of September 30, 2020 and fund the repurchase of a former executive’s time-based options, as described in Footnote 12, Stock-Based Compensation for more information. On December 24, 2020, DoubleVerify paid $68.0 million of its outstanding balance under the New Revolving Credit Facility. As of December 31, 2020, $22.0 million was outstanding under the New Revolving Credit Facility due at maturity.

Income Tax

9.     Income Tax

The Company’s quarterly income tax provision is calculated using an estimated annual effective income tax rate ("ETR") based on actual historical information and forward-looking estimates. The Company’s estimated annual ETR may fluctuate due to changes in forecasted annual pre-tax income, changes in the jurisdictional mix of forecasted pre-tax income, and changes to actual or forecasted permanent book to tax differences (e.g., non-deductible expenses). In addition, the Company’s ETR for a particular reporting period may fluctuate as the result of changes to the valuation allowance for net deferred tax assets, the impact of anticipated tax settlements with federal, state, or foreign tax authorities, or the impact of tax law changes. The Company identifies items that are unusual and non-recurring in nature and treat these as discrete events. The tax effect of these discrete events is booked entirely in the quarter in which they occur.

During the three and nine months ended September 30, 2021, the Company recorded an income tax provision of $3.3 million and $8.4 million, respectively, resulting in an effective tax rate of 29.2% and 89.3%, which includes an annualized effective tax provision of $3.3 million and $2.7 million (representing an effective tax rate of 29.2% and 29.1%) and discrete items relating primarily to transaction costs and state tax refunds of $0 and $5.6 million (representing an effective tax rate of 0.0% and 60.2%), respectively. During the three and nine months ended September 30, 2020, the Company recorded an income tax benefit of $1.4 million and an income tax provision of $2.0 million, respectively, resulting in an effective tax rate of (31.1%) and 13.8%, respectively. These effective tax rates differ from the U.S. federal statutory rate primarily due to the effects of differing treatment of transaction costs between book and tax, foreign tax rate differences, U.S. tax on foreign operations, and U.S. state/local taxes.

The COVID-19 (as defined herein) pandemic has a global reach, and many countries are introducing measures that provide relief to taxpayers in a variety of ways. In March 2020, the U.S. government enacted tax legislation containing provisions to support businesses during the COVID-19 pandemic (the “CARES Act”), including deferment of the employer portion of certain payroll taxes, refundable payroll tax credits, and technical amendments to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company’s income tax provision for the three and nine months ended September 30, 2021.

A valuation allowance has been established against a non-material amount of certain net foreign deferred tax assets and US tax loss carryforward. All other net deferred tax assets have been determined to be more likely than not realizable.

The Company and its subsidiaries file income tax returns with the Internal Revenue Service (“IRS”) and various state and international jurisdictions. The Company’s Israeli subsidiary is under audit by the Israeli Tax Authority for the 2016-2018 tax years. This examination may lead to ordinary course adjustments or proposed adjustments to the Company’s taxes. Aside from this, the Company is not currently under audit in any other jurisdiction.

On August 31, 2021, the Company acquired all of the outstanding stock of Meetrics, a German corporation, in a sale treated as a non-taxable event at the corporate level. The Company has calculated a preliminary tax basis balance sheet and deferred tax impact of the acquisition. The Company has recorded a deferred tax liability of $2.9 million relating to varying tax and book basis differences of intangible assets and goodwill.

In addition, Meetrics maintains net operating loss carryforwards of approximately $5.0 million through December 31, 2020. Based on a preliminary review of all positive and negative evidence, it appears to not be more likely than not that Meetrics will be able to utilize these loss carryforwards. Therefore, a deferred tax asset of $1.5 million has been recorded, which is fully offset by a valuation allowance.

Income Tax Provision (Benefit)

The Company’s effective tax rate for the year ended December 31, 2020 was lower than the U.S. federal statutory income tax rate primarily due to the impact of non-deductible non-cash compensation, certain tax credits, foreign taxes, provision to return adjustments and the impact of other permanent book-tax differences. For the year ended December 31, 2019, the Company’s effective tax rate was higher than the U.S. federal statutory income tax rate primarily due to the impact of state and local income taxes, certain tax credits, and the impact of other permanent book-tax differences. For the year ended December 31, 2018, the Company’s effective tax rate was lower than the U.S. federal statutory income tax rate primarily due to a one-time tax benefit of return to provision adjustments related to deductible transaction costs, offset by state and local income taxes, changes in statutory rates, and other permanent book-tax differences.

Deferred Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax reporting purposes. The following table details the components of deferred tax assets and liabilities as of December 31, 2020:

	As of December 31,
(in thousands)	2020		2019
Deferred tax assets:
Allowance for doubtful accounts	$	1,819	$	1,366
Accrued expenses and other		5,307		4,026
Net operating losses		1,298		1,978
Gross deferred tax assets		8,424		7,370
Valuation allowance		(484)		(88)
Net deferred tax assets	$	7,940	$	7,282
Deferred tax liabilities:
Purchased intangibles	$	(35,561)	$	(41,180)
Depreciation and amortization		(3,715)		(2,574)
Total deferred tax liabilities		(39,276)		(43,754)
Net deferred tax liabilitiy	$	(31,336)	$	(36,472)

The Company has not recorded a deferred tax liability for foreign withholding or other foreign local tax on the undistributed earnings from the Company’s international subsidiaries as such earnings are considered to be indefinitely reinvested.

Tax Valuation Allowance

The Company’s deferred tax assets and liabilities are primarily comprised of purchased intangibles, book to tax differences in depreciation and amortization, book and tax differing treatment of accruals, and net operating losses. As of each reporting date, management considers new evidence, both positive and negative, that could impact management’s view with regard to the future realization of deferred tax assets. As of December 31, 2020, (i) the Company’s taxable temporary differences will provide sufficient US future taxable income to realize the US deferred tax assets and (ii) the Company’s projected future pre-tax book income in the US and respective foreign countries is expected to provide sufficient taxable income to realize the deferred tax assets within each jurisdiction’s respective statutory carryforward period. Based on this analysis, the Company has concluded that it is more likely than not that the Company will realize most of its US and foreign deferred taxes assets. A valuation allowance is assessed to a small amount of foreign capital losses and US tax loss carryforwards.

Net Operating Loss and Credit Carryforwards

As of December 31, 2020, the Company had a Federal net operating loss carryforward of approximately $0.3 million and a state net operating loss carryforward of approximately $10.9 million. In addition, the Company had loss carryforwards for various foreign countries where the Company has business operations. The aggregate amount of foreign loss carryover is not material as of December 31, 2020. Federal net operating loss carryforwards can be used to offset against taxable income in the future and begin to expire in 2031. The Company utilized approximately $3.0 million and $2.7 million of Federal and state net operating loss carryforwards, respectively, in 2020. Utilization of Federal net operating loss carryforwards may be subject to annual limitations due to the “change in ownership” provisions of the Internal Revenue Code of 1986 and similar state provisions. The Company’s net operating loss carryforwards are subject to the annual limitation under Section 382 of the Internal Revenue Code.

Uncertain Tax Positions

The Company’s income tax returns are open to examination by federal and state authorities for the tax years ended December 31, 2016 and later. However, the Company believes that its tax positions are all highly certain of being upheld upon examination and intends to defend those positions if challenged by the Internal Revenue Services or another taxing jurisdiction.

For uncertain tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. The Company has unrecognized tax benefits, which are tax benefits related to uncertain tax positions which have been or will be reflected in income tax filings that have not been recognized in the financial statements due to potential adjustments by taxing authorities in the applicable jurisdictions. The Company’s liabilities for unrecognized tax benefits, which include interest and penalties, were $1.9 million and $0.6 million as of December 31, 2020 and 2019, respectively. The amount of unrecognized tax benefits that, if recognized, would affect the Company’s effective tax rate are $1.8 million and $0.5 million as of December 31, 2020 and 2019, respectively and include the federal tax benefit of state deductions. The Company anticipates that no unrecognized tax benefits will reverse during the next year due to the expiration of statutes of limitation.

Changes in the Company’s unrecognized tax benefits are as follows:

Employee Equity Incentive Plan

On September 20, 2017, the Company established its 2017 Omnibus Equity Incentive Program (the “2017 Plan”) which provides for the granting of equity based awards to certain employees, directors, independent contractors, consultants and agents. Under the 2017 Plan, the Company may grant non-qualified stock options, stock appreciation rights, restricted stock units, and other stock-based awards for up to 22,182 shares of common stock.

On April 19, 2021 the Company established its 2021 Omnibus Equity Incentive Plan (“2021 Equity Plan”). The maximum number of shares of common stock available for issuance under the 2021 Equity Plan is equal to the sum of (i) 30,000 shares of common stock and (ii) an annual increase on the first day of each year beginning in 2022 and ending in and including 2031, equal to the lesser of (A) five percent (5%) of the outstanding shares of common stock on the last day of the immediately preceding fiscal year and (B) such lesser amount as determined by the Board’s compensation committee. The 2021 Equity Plan provides for the grant of stock options (including qualified incentive stock options and nonqualified stock options), stock appreciation rights, restricted stock, restricted stock units, dividend equivalents, and other stock or cash settled incentive awards. Any shares covered by an award, or portion of an award, granted under the 2021 Equity Plan that expires or is forfeited, canceled, cash-settled, or otherwise terminated for any reason will again be available for the grant of awards under the 2021 Equity Plan.

Options become exercisable subject to vesting schedules up to four years from the date of the grant and subject to certain timing restrictions upon an employee’s separation of service and no later than 10 years after the grant date.

Restricted stock units are subject to vesting schedules up to four years from the date of the grant and subject to certain timing restrictions upon an employee’s separation.

A summary of stock option activity as of and for the nine months ended September 30, 2021 and December 31, 2020 is as follows:

Stock options include grants to executives that contain both market-based and performance-based vesting conditions. There were no stock options granted that contain both market-based and performance-based vesting conditions during the nine months ended September 30, 2021. As of September 30, 2021, 3,433 market-based and performance-based awards were outstanding. As of September 30, 2021, the Company did not consider the performance condition to be probable and did not recognize any expense associated with these options.

The weighted average grant date fair value of options granted during the nine months ended September 30, 2021 and 2020 was $12.85 and $2.40, respectively. The total intrinsic value of options exercised during the nine months ended September 30, 2021 and 2020 was $50.5 million and $0.5 million, respectively.

The fair market value of each option granted during the nine months ended September 30, 2021 has been estimated on the grant date using the Black-Scholes-Merton option-pricing model with the following assumptions:

	2021
Risk - free interest rate (percentage)	0.6. - 1.1
Expected term (years)	5.9 - 6.1
Expected dividend yield (percentage)	—
Expected volatility (percentage)	42.1 - 43.6

The Company’s board of directors (the “Board”) did not declare or pay dividends of the Company’s common or preferred stock during the nine months ended September 30, 2021 or during the nine months ended September 30, 2020.

A summary of restricted stock unit activity as of and for the nine months ended September 30, 2021 and December 31, 2020 is as follows:

Employee Stock Purchase Plan

In March 2021, the Board approved the Company’s 2021 Employee Stock Purchase Plan (“ESPP”), and employees became eligible to enroll in August 2021. The ESPP qualifies as an “employee stock purchase plan” under Section 423 of the U.S. Internal Revenue Code of 1986, as amended.

The Company reserved 3,000 shares of common stock for sale under the ESPP. The share reserve increases on the first day of each calendar year beginning on January 1, 2022 and ending on and including January 1, 2031, equal to the lesser of (i) one percent (1%) of the aggregate number of shares of common stock outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number of shares of common stock as is determined by the Board.

Purchases are accomplished through participation in discrete offering periods. Currently, the ESPP is available only to U.S. based employees; the Company is reviewing offering the ESPP program to employees in non-U.S. jurisdictions. The first offering and purchase period began on September 1, 2021 and will end on November 30, 2021. The Company expects the program to continue consecutively for six-month offering periods (commencing on December 1, 2021) for the foreseeable future.

Under the ESPP, eligible employees are able to acquire shares of the Company’s common stock by accumulating funds through payroll deductions. Company employees in the United States generally are eligible to participate in the ESPP if they are a full-time employee and have completed six months of continuous service with the Company as of the last day of the enrollment period. Eligible employees are able to select a rate of payroll deduction between 1% and 15% of their compensation, up to a $25 annual contribution limit. The purchase price for shares of common stock purchased under the ESPP is 85% of the lesser of the fair market value of the common stock on (i) the first trading day of the applicable offering period and (ii) the last trading day of the applicable offering period. An employee’s participation automatically ends upon termination of employment for any reason. A participant may cancel enrollment or lower their contributions once during an offering period, but no later than 30 days before the end of an offering period. Upon the termination of an employee’s participation in the ESPP, payroll deductions will be stopped and refunded.

Stock-based compensation expense for the ESPP is recognized on a straight-line basis over the requisite service period of each award. The ESPP also has a six-month holding period after the purchase date of the offering period. Stock-based compensation expense related to ESPP totaled less than $0.1 million for the three and nine months ended September 30, 2021.

12. Stock-Based Compensation

Employee Stock Option Plan

On September 20, 2017, the Company established an Equity Incentive Program (the “Plan”) which provides for the granting of incentive and nonqualified stock options to certain employees, directors, independent contractors, consultants and agents. Under the Plan, the Company may grant non-qualified stock options, stock appreciation rights, restricted stock units, and other stock-based awards up to 22,182 shares of Common Stock.

Options become exercisable subject to vesting schedules up to four years from the date of the grant and subject to certain timing restrictions upon an employee’s separation of service and no later than 10 years after the grant date.

Restricted stock units are subject to vesting schedules up to two years from the date of the grant and subject to certain timing restrictions upon an employee’s separation.

A summary of stock option activity as of and for the years ended December 31, 2020, 2019 and 2018 is as follows:

Stock options include grants to executives that contain both market-based and performance-based vesting conditions. During the year ended December 31, 2020, the Company granted 600 stock options that contain both market-based and performance-based vesting conditions and 167 of restricted stock units that contain market-based vesting conditions. The Company repurchased and cancelled 956 of stock options that contain both market-based and performance-based vesting conditions resulting in $14.5 million in incremental cash-based compensation expense related to the transaction, and vested 167 of restricted stock units with market-based vesting conditions. As of December 31, 2020, 3,433 market-based and performance-based awards were outstanding. As of December 31, 2020, the Company did not consider the performance condition to be probable and did not recognize any expense associated with those options.

The Company repurchased and cancelled 2,606 vested stock options from a former executive during the year ended December 31, 2020 for an aggregate purchase price of approximately $15.5 million recorded in Additional Paid-in Capital on the Company’s Consolidated Balance Sheets.

The weighted average grant date fair value of options granted for the years ended December 31, 2020, 2019, and 2018 was $2.67, $1.41 and $0.51, respectively. The total intrinsic value of options exercised during the years ended December 31, 2020, 2019 and 2018 was $3.6 million, $0.3 million and nil, respectively.

The fair market value of each option granted for the years presented has been estimated on the grant date using the Black-Scholes-Merton option-pricing model with the following assumptions:

Capital Leases

As of September 30, 2021, the Company had seven lease agreements for certain equipment which provide for the transfer of ownership at the end of the lease term or are for underlying assets that will have an insignificant fair value at the end of the lease term. The Company has classified these agreements as capital leases and recognized the corresponding assets and liabilities within the Condensed Consolidated Balance Sheet.

The following is a schedule of future minimum lease payments under these agreements (including interest) as of September 30, 2021.

Contingencies

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. The Company records liabilities for contingencies including legal costs when it is probable that a liability has been incurred and when the amount can be reasonably estimated. Legal costs are expensed as incurred. 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 effect on the Company’s business, financial condition, results of operations or cash flows.

With respect to potential payments due related to the Zentrick acquisition, discussed in Footnote 4, Business Combinations, the Company and the Zentrick selling stockholders are currently in discussions to negotiate the early termination of the Zentrick Deferred Payment Terms and resolution of the contingent payments due for both the technical milestones and revenue targets. The Company believes the total of approximately $2.8 million for these potential payments reflected in the Condensed Consolidated Balance Sheet as contingent consideration current and other current liabilities reflect the Company’s estimated obligations under the stock purchase agreement entered into in connection with the transaction, as of September 30, 2021. In efforts to terminate early the Zentrick Deferred Payment Terms, the Company believes payment between $2.8 million and $5.5 million is possible, with no amount within the range being a better estimate than the amount recorded on the Condensed Consolidated Balance Sheets.

The accompanying Condensed Consolidated Balance Sheets as of September 30, 2021 and December 31, 2020, the Condensed Consolidated Statements of Operations and Comprehensive Income for the three and nine months ended September 30, 2021 and 2020, the Condensed Consolidated Statements of Stockholders’ Equity for the three and nine months ended September 30, 2021 and 2020, and the Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2021 and 2020 reflect all adjustments that are of a normal recurring nature and that are considered necessary for a fair presentation of the results for the periods shown in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the applicable rules and regulations of the SEC for interim financial reporting periods. Accordingly, certain information and footnote disclosures have been condensed or omitted pursuant to SEC rules that would ordinarily be required under GAAP for complete financial statements. These unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements as of December 31, 2020 and 2019 and for the years then ended and the accompanying notes thereto included in the Company’s Prospectus.

On March 29, 2021, the Company effected a 1-for-3 reverse stock split (‘‘reverse stock split’’) of its outstanding common stock, par value $0.001 per share (“common stock”), and a proportional adjustment to the existing conversion ratio of its then-outstanding Series A Preferred Stock, par value $0.01 per share (“preferred stock”). Accordingly, all share and per share amounts for all periods presented in these Condensed Consolidated Financial Statements and notes thereto, have been adjusted retrospectively, where applicable, to reflect this reverse stock split.

Basis of Preparation and Principles of Consolidation

The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and reflect the financial statements of the Company and all of its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

On March 29, 2021, the Company effected a 1-for-3 reverse stock split (“reverse stock split”) of its outstanding common stock and a proportional adjustment to the existing conversion ratio for the preferred stock described in Footnote 13, Stockholders’ Equity.

Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements

Use of Estimates and Judgments in the Preparation of the Condensed Consolidated Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenue and expense during the reporting periods. Significant estimates and judgments are inherent in the analysis and measurement of items including, but not limited to: revenue recognition criteria including the determination of principal versus agent revenue considerations, income taxes, the valuation and recoverability of goodwill and intangible assets, the assessment of potential loss from contingencies, the allowance for doubtful accounts, and assumptions used in determining the fair value of stock-based compensation. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. These estimates are based on the information available as of the date of the Condensed Consolidated Financial Statements.

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with certain new or revised accounting standards.

Financial Instruments - Credit Losses

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), 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 accounts receivable. This guidance is effective for annual reporting periods beginning after December 15, 2022 for non-public entities, including interim periods within that reporting period. Early adoption is permitted and the update allows for a modified retrospective method of adoption. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Cloud Computing

In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (“ASU 2018-15”). This update was issued to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The amendments in ASU 2018-15 are effective for annual periods beginning after December 15, 2020 for non-public entities, and interim periods within annual periods beginning after December 15, 2021. The update allows for a retrospective or prospective method of adoption.

The Company intends to adopt amendment ASU No. 2018-15 on December 31, 2021 using a prospective approach. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases Topic 842 (“ASU 2016-02”). The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC 840, Leases. ASU 2016-02 requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases, along with additional qualitative and quantitative disclosures. In July 2018, FASB issued ASU No. 2018- 10, Codification Improvements to Topic 842, Leases, ("ASU No. 2018-10") to further clarify,

correct and consolidate various areas previously discussed in ASU 2016-02. FASB also issued ASU No. 2018- 11, Leases: Targeted Improvements ("ASU 2018-11") to provide entities another option for transition and lessors with a practical expedient. The transition option allows entities to not apply ASU No. 2016-02 in comparative periods in the financial statements in the year of adoption. The amendments in ASU No. 2016-02, ASU No. 2018-10 and ASU No. 2018-11 are effective for fiscal years beginning after December 15, 2021 for non-public entities and interim periods within fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently in the process of evaluating the impact of this standard on the Company’s Condensed Consolidated Financial Statements.

Simplifying the Accounting for Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”). ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. For non-public entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. Certain amendments included in the update allows for a retrospective, modified retrospective, or prospective method of adoption. The Company is currently in the process of evaluating the impact of this standard and its adoption is not expected to have a material impact on the Company’s Condensed Consolidated Financial Statements.

ASU 2019-12 issued guidance on the accounting for income taxes that, among other provisions, eliminates certain exceptions to existing guidance related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. This guidance also requires an entity to reflect the effect of an enacted change in tax laws or rates in its effective income tax rate in the first interim period that includes the enactment date of the new legislation, aligning the timing of recognition of the effects from enacted tax law changes on the effective income tax rate with the effects on deferred income tax assets and liabilities. Under existing guidance, an entity recognizes the effects of the enacted tax law change on the effective income tax rate in the period that includes the effective date of the tax law. This guidance is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements.

Reference Rate Reform

In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU No. 2020-04”). The amendment in this update provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment in this update applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendment does not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendment in this update is effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted this amendment on March 12, 2020. There was no impact to the Consolidated Financial Statements for the year ended December 31, 2020. The Company continues to monitor the transition of LIBOR to alternative reference rate measures.
