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

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the consolidated financial statements and the related notes to those statements included in Item 8 to this Annual Report on Form 10-K. In addition to historical financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, beliefs, and expectations and that involve risks and uncertainties. Our actual results and the timing of events could differ materially from those discussed in these forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report on Form 10-K, particularly in "Item 1A. Risk Factors" and the "Special Note About Forward-Looking Statements."

Overview and Trends

See "Item 1. Business" for an overview of our business, the industry in which we operate, and important industry trends.

Recent Developments

Telaria Merger, SpotX and SpringServe Acquisitions

On April 1, 2020, we completed the Telaria Merger, and on April 30, 2021, we completed the SpotX Acquisition. These transactions were transformative and have resulted in what we believe to be the world’s largest independent sell-side advertising platform and ad server, with scale, capabilities, and solutions exceeding those offered by competitors. We offer a single partner for transacting CTV, desktop display, video, audio and mobile inventory across all geographies and auction types.

As CTV viewership is growing rapidly and the pace of adoption is accelerating the shift of advertising budgets from linear television to CTV, these transactions have strategically positioned us to take advantage of this trend, and we believe that CTV will be our biggest growth driver in future periods.

The SpotX Acquisition resulted in a significant increase in our revenue and Revenue ex-TAC (as defined in section "Key Operating and Financial Performance Metrics"), in particular in CTV and online video. Following the transaction, the percentage of our revenue attributable to CTV increased significantly, and because CTV is largely transacted through reserve auctions, these types of auctions have become a more significant portion of the transactions on our platform. The acquisition also resulted in an increase in related operating expenses, primarily associated with costs for personnel, data center and hosting costs, facilities, payments to sellers for revenue reported on a gross basis, and other ancillary costs to support the business. We expect some of those increases to be offset by cost saving activities that began in the second quarter of 2021 and continue to be in process. We are targeting in excess of $35 million in run-rate operating cost synergies over a two year period. As of December 31, 2021, we have achieved more than half of our cost synergy target on a run-rate basis.

The SpringServe Acquisition, which we completed in July 2021, expanded our video and CTV offering to include ad server functionality in addition to our programmatic SSP capabilities. The SpringServe ad server manages multiple aspects of video advertising for both programmatic transactions and inventory sold directly by the publisher, including forecasting, routing, customized ad experiences, and advanced podding logic. Combined with our SSP, the SpringServe ad server provides publishers a holistic yield management solution that works across their entire video advertising business to drive value. This is of particular importance for CTV publishers, who still sell a large percentage of their inventory through their direct sales team. We believe the acquisition of SpringServe is highly strategic as it allows us to offer publishers an independent full-stack solution to the walled gardens, which can be leveraged across their entire video advertising business.

Impact of COVID-19 Pandemic and Other Recent Developments

The COVID-19 pandemic and resulting global disruptions have negatively affected our revenue, results of operations, cash flows, and financial condition. Our business depends on the overall demand for advertising and on the economic health of our current and prospective sellers and buyers. In response to the pandemic and associated economic challenges, a significant number of advertisers, in particular with respect to certain categories of advertising that were particularly impacted by the pandemic and resulting stay-at-home orders, reduced their advertising budgets, resulting in an overall decrease in advertising spend through our platform compared to our pre-COVID expectations. This decrease was particularly pronounced through the first half of 2020, where we experienced a significant decline in our revenues compared to our expectations. Our revenue trends improved significantly during the third and fourth quarters of 2020 as our revenue returned to positive growth.

During the first half of 2021, revenue from a number of advertising categories returned to pre-COVID spending levels, while certain categories including travel, auto, and entertainment remained below pre-COVID spending levels. In the second half of 2021, we continued to see lower levels of spending in travel and auto, in part due to global supply chain disruptions, and also faced challenges due to government stay-at-home orders in certain markets such as Australia. These factors were exacerbated by the

45

spread of the Omicron variant in December 2021, which resulted in renewed macro-economic challenges. We expect such challenges to persist through the first quarter of 2022 and it is possible that they will increase in scope.

Due to the substantial uncertainties associated with the COVID-19 pandemic, the extent to which the pandemic (and actions taken in response to it by governments, businesses, and individuals) and other direct and indirect impacts of the pandemic will ultimately impact our business and is currently unknown, and depends on various factors, many of which are outside of our control. Refer to Item 1A. "Risk Factors" for additional information related to this risk.

2021 Channel Trends

Sellers use our technology to monetize their content across all digital channels, including CTV, mobile and desktop, and each of these channels will continue to represent a meaningful portion of our revenue in future periods. We track the breakdown of revenue across channels to better understand how our clients are transacting on our platforms, which informs decisions as to business strategy and the allocation of resources and capital.

Each of these digital channels has its own industry growth rate, with CTV and mobile projected to continue to grow steadily, while desktop growth flattens. MAGNA's October 2021 Programmatic Market forecast has estimated compound annual growth rates from 2021 to 2025 for mobile and desktop at 18% and 2%, respectively, and over the same period, eMarketer projected CTV to grow at a 24% compound annual growth rate.

We believe that CTV will be our biggest growth driver in future periods, and following the SpotX Acquisition we expect CTV revenue to represent a significantly higher percentage of our overall revenue compared to pre-acquisition periods.

We expect our mobile business to grow at a higher rate than desktop, consistent with industry trends and our historical results. Our mobile business consists of two components, mobile web and mobile applications. Initially our mobile business consisted primarily of mobile web, which is similar to our desktop business, but we expect our future growth within mobile to come largely from our mobile applications business and, in particular, mobile video.

Lower industry growth rates in desktop will make growing desktop revenue more challenging; however, in future periods we believe we will be able to grow our desktop business in excess of industry projections by capturing market share through SPO and expansion of publisher relationships. We expect our desktop business to decline as an overall percentage of our revenue in future periods. However, we expect that it will continue to represent a significant part of our revenue in the near term and therefore have a negative effect on our overall growth rate.

Components of Our Results of Operations

We report our financial results as one operating segment. Our consolidated operating results are regularly reviewed by our chief operating decision maker, principally to make decisions about how we allocate our resources and to measure our consolidated operating performance.

Revenue

We generate revenue from the purchase and sale of digital advertising inventory through our platform. Generally, our revenue is based on a percentage of the ad spend that runs through our platform, although for certain clients or transaction types we may receive a fixed CPM for each impression sold, and for advertising campaigns that are transacted through insertion orders we earn revenue based on the full amount of ad spend that runs through our platform. We also generate revenue from the fee we charge clients for use of our Demand Manager header-bidding product and SpringServe ad server product, which we acquired on July 1, 2021. We recognize revenue upon the fulfillment of our contractual obligations in connection with a completed transaction, subject to satisfying all other revenue recognition criteria. For the majority of transactions executed through our platform, we act as an agent on behalf of the publisher that is monetizing its inventory, and revenue is recognized net of any advertising inventory costs that we remit to sellers. With respect to certain revenue streams for managed advertising campaigns that are transacted through insertion orders, we report revenue on a gross basis, based primarily on our determination that the Company acts as the primary obligor in the delivery of advertising campaigns for our buyer clients with respect to such transactions.

Following the SpotX Acquisition, the percentage of our revenue reported on a gross basis increased significantly compared to pre-acquisition periods. During the first quarter of 2021 (prior to the SpotX Acquisition), our revenue reported on a gross basis was less than 3% of total revenue. For the three months ended December 31, 2021, our revenue reported on a gross basis increased to 19% of total revenue. As revenue streams acquired in the SpotX Acquisition continue to increase, the percentage of revenue reported on a gross basis may continue to increase in future periods. Any mix shift that causes an increase in the relative percentage of our revenue accounted for on a gross basis would result in a higher revenue contribution and an associated decrease in our gross margin percentage (with no underlying impact on gross profit or Revenue ex-TAC, as defined in section "Key Operating and Financial Performance Metrics"). Our revenue recognition policies are discussed in more detail in Note 4 of the "Notes to the Consolidated Financial Statements."

Expenses

We classify our expenses into the following categories:

Cost of Revenue. Our cost of revenue consists primarily of data center costs, bandwidth costs, ad protection costs, depreciation and maintenance expense of hardware supporting our revenue-producing platform, amortization of software costs for the development of our revenue-producing platform, amortization expense associated with acquired developed technologies, personnel costs, facilities-related costs, and cloud computing costs. In addition, for revenue booked on a gross basis, cost of revenue includes traffic acquisition costs. Personnel costs included in cost of revenue include salaries, bonuses, and stock-based compensation, and are primarily attributable to personnel in our network operations group who support our platform. We capitalize costs associated with software that is developed or obtained for internal use and amortize the costs associated with our revenue-producing platform in cost of revenue over their estimated useful lives. We amortize acquired developed technologies over their estimated useful lives.

Sales and Marketing. Our sales and marketing expenses consist primarily of personnel costs, including salaries, bonuses, and stock-based compensation, as well as marketing expenses such as brand marketing, travel expenses, trade shows and marketing materials, professional services, and amortization expense associated with client relationships, backlog, and non-compete agreements from our business acquisitions, and to a lesser extent, facilities-related costs and depreciation and amortization. Our sales organization focuses on increasing the adoption of our solution by existing and new buyers and sellers. We amortize acquired intangibles associated with client relationships and backlog from our business acquisitions over their estimated useful lives.

Technology and Development. Our technology and development expenses consist primarily of personnel costs, including salaries, bonuses, and stock-based compensation, as well as professional services associated with the ongoing development and maintenance of our solution, depreciation and amortization, and to a lesser extent, facilities-related costs. These expenses include costs incurred in the development, implementation, and maintenance of internal use software, including platform and related infrastructure. Technology and development costs are expensed as incurred, except to the extent that such costs are associated with internal use software development that qualifies for capitalization, which are then recorded as internal use software development costs, net, on our consolidated balance sheets. We amortize internal use software development costs that relate to our revenue-producing activities on our platform to cost of revenue and amortize other internal use software development costs to technology and development costs or general and administrative expenses, depending on the nature of the related project. We amortize acquired intangibles associated with technology and development functions from our business acquisitions over their estimated useful lives.

General and Administrative. Our general and administrative expenses consist primarily of personnel costs, including salaries, bonuses, and stock-based compensation, associated with our executive, finance, legal, human resources, compliance, and other administrative personnel, as well as accounting and legal professional services fees, facilities-related costs and depreciation and amortization, and other corporate-related expenses. General and administrative expenses also include amortization of internal use software development costs and acquired intangible assets from our business acquisitions over their estimated useful lives that relate to general and administrative functions.

Merger, Acquisition, and Restructuring Costs. Our merger, acquisition, and restructuring costs consist primarily of professional service fees associated with the merger and acquisition activities, including cash-based employee termination costs, stock-based compensation charges, and other restructuring activities, including facility closures, relocation costs, and contract termination costs.

Other (Income) Expense

Interest (Income) Expense, Net. Interest expense consists of interest expense associated with our Convertible Senior Notes and credit facility ("Term Loan B Facility"), and their related amortization of debt issuance costs and debt discount. Interest income consists of interest earned on our cash equivalents.

Other Income. Other income consists primarily of rental income from commercial office space we hold under lease and have sublet to other tenants.

Foreign Currency Exchange (Gain) Loss, Net. Foreign currency exchange (gain) loss, net consists primarily of gains and losses on foreign currency transactions and remeasurement of monetary assets and liabilities on our balance sheet denominated in foreign currencies. Foreign currency monetary assets and liabilities consist primarily of cash and cash equivalents, accounts receivable, accounts payable, and various intercompany balances held between our subsidiaries. Our primary foreign currency exposures are currencies other than the U.S. Dollar, principally the Australian Dollar, British Pound, Canadian Dollar, Euro, and Japanese Yen.

Provision (Benefit) for Income Taxes

We are subject to income taxes in the U.S. (federal and state) and numerous foreign jurisdictions. Tax laws, regulations, administrative practices, principles, and interpretations in various jurisdictions may be subject to significant change, with or without notice, due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating our provision and accruals for these taxes. There are many transactions that occur during the ordinary course of business for which the

ultimate tax determination is uncertain. Our effective tax rates could be affected by numerous factors, such as changes in our business operations, acquisitions, investments, entry into new businesses and geographies, intercompany transactions, the relative amount of our foreign earnings, including earnings being lower than anticipated in jurisdictions where we have lower statutory rates and higher than anticipated in jurisdictions where we have higher statutory rates, losses incurred in jurisdictions for which we are not able to realize related tax benefits, the applicability of special tax regimes, changes in foreign currency exchange rates, changes in our stock price, changes in our deferred tax assets and liabilities and their valuation, changes in the laws, regulations, administrative practices, principles, and interpretations related to tax, including changes to the global tax framework, competition, and other laws and accounting rules in various jurisdictions.

Comparison of the Years Ended December 31, 2021, 2020, and 2019

Revenue

Revenue increased $246.8 million, or 111%, for the year ended December 31, 2021 compared to the prior year. Our revenue growth was driven primarily by organic growth as well as incremental revenue from the SpotX Acquisition, which was completed on April 30, 2021. On a pro forma basis, including revenue for Telaria, SpotX and SpringServe during the relevant pre-acquisition period, revenue increased 30% for the year ended December 31, 2021 compared to the prior period, primarily due to growth in all channels, mainly driven by CTV and mobile, and a rebound from impacts of the COVID-19 pandemic, which were particularly pronounced in the first half of 2020.

Revenue increased $65.2 million, or 42%, for the year ended December 31, 2020 compared to the prior year. Our revenue growth was driven primarily by the Telaria Merger, completed on April 1, 2020, which contributed $60.1 million in revenue during the year ended December 31, 2020. On a per channel basis, CTV revenue increased $34.3 million, compared to the prior year (all as a result of the Telaria Merger), while mobile revenue increased $20.2 million, or a 23%, compared to the prior year, and desktop revenue increased $10.7 million, or 16%, compared to the prior year. Excluding the impact of the Telaria Merger, our revenue increased 3% year-over-year. Despite some recovery in our revenue trends beginning in the third quarter of 2020, our overall annual revenue growth was significantly negatively affected by the impact of the COVID-19 pandemic.

We expect our revenue will increase in 2022 compared to 2021, as a result of organic growth and contributions from recently acquired businesses, in particular with respect to our CTV revenue. Our revenue is largely a function of the number of advertising transactions and the price, or CPM, at which the inventory is sold, which results in total advertising spend on our platform, and, with respect to our revenue reported on a net basis, the take rate we charge for our services. Because pricing and take rate vary across publisher, channel and transaction type, our revenue is impacted by shifts in the mix of advertising spend on our platform. We believe that contributions to revenue from reserve auctions, in particular with respect to CTV which is largely transacted on a reserved basis, will continue to grow as a percentage of our total revenue. In general, we expect this shift will have a net positive impact on our revenue due to both an increase in the volume of transactions and average CPM, despite the fact that reserve auctions generally carry a lower take rate compared to open auction transactions.

Our revenue growth has been tempered, and may be negatively impacted in the future, by reductions in revenue resulting from the economic impact of the COVID-19 pandemic. Refer to Item 1A. "Risk Factors" for additional information related to this risk factor and the impact it may have on our business.

Cost of Revenue

Cost of revenue increased by $123.9 million, or 159%, for the year ended December 31, 2021 compared to the prior year primarily due to an increase in traffic acquisition cost of $49.9 million driven by the increase in revenue reported on a gross basis as a result of the SpotX Acquisition, an increase in depreciation and amortization expenses of $43.2 million also associated with the SpotX Acquisition, and an increase in data and bandwidth expenses of $21.4 million.

50

Table of Contents

Cost of revenue increased $20.4 million, or 35%, for the year ended December 31, 2020 compared to the year ended December 31, 2019 primarily due to the Telaria Merger. Cost of revenue includes an increase of $11.8 million in data and bandwidth expenses, $4.5 million in depreciation and amortization, and $2.0 million in media costs.

Our cost of revenue will continue to increase in future periods primarily due to the impacts of recently completed acquisitions that have expanded the size of our revenue and expense base, increases in hosting costs and other expenses to support the growth of our business, increases in traffic acquisition costs associated with revenue reported on a gross basis, and an increase in amortization of intangible assets resulting from the Telaria Merger and the SpotX Acquisition.

Cost of revenue may fluctuate from quarter to quarter and period to period, on an absolute dollar basis and as a percentage of revenue, depending on revenue levels and the volume of transactions we process supporting those revenues, and the timing and amounts of depreciation and amortization of equipment and software.

Sales and Marketing

Sales and marketing expenses increased by $94.4 million, or 124%, for the year ended December 31, 2021 compared to the prior year primarily due to an increase of $54.1 million in amortization of acquired intangibles and other assets as a result of the SpotX Acquisition and the Telaria Merger as well as increases in headcount from the SpotX Acquisition, resulting in an additional $36.8 million of personnel related expenses.

Sales and marketing expenses increased by $31.5 million, or 71%, for the year ended December 31, 2020 compared to the year ended December 31, 2019 primarily due to the Telaria Merger and associated increases in amortization related to acquired intangibles and other assets and increases in headcount. Sales and marketing expenses increased by $20.4 million related to personnel expenses and $12.8 million related to depreciation and amortization associated with the Telaria Merger. These increases were partially offset by a decrease in expenses of $2.4 million related to travel and industry events due to the impact of the COVID-19 pandemic.

We expect sales and marketing expenses to increase in 2022 compared to 2021 in absolute dollars primarily due to a full year of additional headcount costs and amortization of acquired intangible assets as a result of the SpotX Acquisition, new hiring to support our growth, and increases in travel and entertainment expenses.

Sales and marketing expenses may fluctuate quarter to quarter and period to period, on an absolute dollar basis and as a percentage of revenue, based on revenue levels, the timing of our investments and seasonality in our industry and business.

Technology and Development

Technology and development expenses increased by $22.9 million, or 44%, for the year ended December 31, 2021 compared to the prior year, primarily due to an increase of $21.2 million in personnel costs as a result of the increased headcount associated with the SpotX Acquisition and a full-year of results from the Telaria Merger.

Technology and development expenses increased by $11.3 million, or 28%, for the year ended December 31, 2020 compared to the year ended December 31, 2019, primarily due to an increase of $11.6 million in personnel costs as a result of the increased headcount associated with the Telaria Merger.

We expect technology and development expenses to increase in 2022 compared to 2021 in absolute dollars, primarily due to a full year of additional headcount costs related to the SpotX and SpringServe Acquisitions and new hiring to support our growth.

The timing and amount of our capitalized development and enhancement projects may affect the amount of technology development costs expensed in any given period. As a percentage of revenue, technology and development expense may fluctuate from quarter to quarter and period to period based on revenue levels, the timing and amounts of technology and development efforts, the timing and the rate of the amortization of capitalized projects and the timing and amounts of future capitalized internal use software development costs.

General and Administrative

General and administrative expenses increased by $11.8 million, or 22%, for the year ended December 31, 2021 compared to the prior year, primarily due to increases of $6.3 million in personnel expenses, $1.5 million in professional services, and $1.1 million in software license mainly attributed to the growth of the overall business as a result of the SpotX Acquisition.

General and administrative expenses increased by $13.2 million, or 33%, for the year ended December 31, 2020 compared to the year ended December 31, 2019, primarily due to increases of $7.1 million in personnel expenses and $4.0 million in facilities related expenses, both primarily associated with the Telaria Merger. In addition, professional services increased by $3.0 million mainly attributed to the growth of the overall business as a result of the Telaria Merger. These increases were partially offset by a decrease in bad debt expense of $1.3 million.

We expect general and administrative expenses to increase in 2022 compared to 2021 in absolute dollars primarily due to a full year of additional headcount costs related to the SpotX Acquisition and new hires to support our overall growth, as well as additional costs assuming a return to office work environment in 2022.

51

Table of Contents

General and administrative expenses may fluctuate from quarter to quarter and period to period based on the timing and amounts of expenditures in our general and administrative functions as they vary in scope and scale over periods. Such fluctuations may not be directly proportional to changes in revenue.

Merger, Acquisition, and Restructuring Costs

We incurred merger, acquisition, and restructuring costs of $38.2 million and $17.6 million during the years ended December 31, 2021 and 2020, respectively, primarily related to the SpotX and SpringServe Acquisitions, which were completed on April 30, 2021 and July 1, 2021, respectively, and the Telaria Merger, which was completed on April 1, 2020. In 2021, these costs included professional fees related to investment banking advisory, legal, and other professional service fees of $28.4 million, one-time cash-based employee termination benefit costs of $6.2 million, facility closure costs of $2.5 million, and non-cash stock-based compensation expense associated with double-trigger accelerations and severance benefits of $1.1 million. Costs incurred in 2020 included professional services of $9.9 million, one-time cash-based employee termination benefit costs of $5.7 million, and non-cash stock-based compensation expense and severance benefits of $1.9 million.

Merger, acquisition, and restructuring costs increased by $15.5 million for the year ended December 31, 2020 compared to the year ended December 31, 2019 primarily due to increased professional services and cash and non-cash acceleration and termination benefits, as referenced above, associated with the Telaria Merger and resulting restructuring activities.

Other (Income) Expense, Net

Year Ended

(in thousands)

Interest (income) expense, net $ 19,848 $ (50) $ (789)

Interest expense, net increased by $19.9 million during the year ended December 31, 2021 compared to the prior year, mainly due to interest expense associated with the Convertible Senior Notes (defined below), which the Company entered into during March 2021, and interest expense associated with the Term Loan B Facility (defined below), which the Company entered into during April 2021, both in connection with the closing of the SpotX Acquisition. Interest (income) expense, net was immaterial in the years ended December 31, 2020 and 2019.

Other income increased by $0.8 million and $3.4 million during the years ended December 31, 2021 and 2020, respectively, compared to the prior years due to a subleased property acquired from the Telaria Merger in April 2020 and additional subleases entered into in 2021 and 2020.

Foreign exchange (gain) loss, net is impacted by movements in exchange rates and the amount of foreign currency-denominated cash, receivables, and payables, which are impacted by our billings to buyers, payments to sellers, and intercompany balances. The foreign currency gain, net during the year ended December 31, 2021 was primarily attributable to the currency movements between the British Pound, Australian Dollar, Canadian Dollar, and Euro relative to the U.S. Dollar. The foreign currency loss, net during the year ended December 31, 2020 was primarily attributable to the currency movements between the same foreign currencies mentioned above relative to the U.S. Dollar and the foreign currency loss, net during the year ended December 31, 2019 was primarily attributable to the currency movements between the British Pound and the Euro relative to the U.S. Dollar.

Provision (Benefit) for Income Taxes

We recorded an income tax benefit of $95.1 million for the year ended December 31, 2021 compared to an income tax expense of $0.7 million and income tax benefit of $1.5 million for the years ended December 31, 2020 and 2019, respectively. The tax benefit for the year ended December 31, 2021 was primarily the result of the deferred tax liability associated with acquisitions that occurred during the year and the tax liability associated with foreign subsidiaries. The tax expense for the year ended December 31, 2020 was primarily the result of the domestic valuation allowance and the tax liability associated with foreign subsidiaries. The tax benefit for the year ended December 31, 2019 was the result of a deferred tax liability associated with the RTK.io acquisition, the release of a foreign valuation allowance resulting from a change to a cost-plus arrangement for a foreign subsidiary, the domestic valuation allowance, and the tax liability associated with foreign subsidiaries.

Key Operating and Financial Performance Metrics

In addition to our GAAP results, we review non-GAAP financial measures, including Revenue ex-TAC and Adjusted EBITDA, to help us evaluate our business on a consistent basis, measure our performance, identify trends affecting our business, establish budgets, measure the effectiveness of investments in our technology and development and sales and marketing, and assess

our operational efficiencies. Our non-GAAP financial measures are discussed below. Revenue and net income (loss) are discussed above under the headings "Components of Our Results of Operations" and "Results of Operations."

Financial Measures and non-GAAP Financial Measures:

Revenue ex-TAC

Revenue ex-TAC is revenue excluding traffic acquisition cost ("TAC"). Traffic acquisition cost, a component of Cost of revenue, represents what we must pay sellers for the sale of advertising inventory through our platform for revenue reported on a gross basis. In calculating Revenue ex-TAC, we add back the cost of revenue, excluding TAC, to gross profit, the most comparable GAAP measurement. Revenue ex-TAC is a non-GAAP financial measure. Our management believes Revenue ex-TAC is a useful measure in assessing the performance of Magnite as a combined company following the SpotX Acquisition and facilitates a consistent comparison against our core business without considering the impact of traffic acquisition costs related to revenue reported on a gross basis.

Our use of Revenue ex-TAC has limitations as an analytical tool and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. A potential limitation of this non-GAAP financial measure is that other companies, including companies in our industry which have similar business arrangements, may define Revenue ex-TAC differently, which may make comparisons difficult. Because of these and other limitations, you should consider our non-GAAP measures only as supplemental to GAAP-based financial performance measures, including revenue, net income (loss) and cash flows.

The following table presents the calculation of gross profit and reconciliation of gross profit to Revenue ex-TAC for the years ended December 31, 2021, 2020, and 2019, respectively:

Channel:

Revenue ex-TAC increased $196.9 million, or 90%, for the year ended December 31, 2021 compared to the year ended December 31, 2020. The increase in Revenue ex-TAC was primarily due to contributions from the SpotX and SpringServe Acquisitions and the Telaria Merger, which were completed on April 30, 2021, July 1, 2021, and April 1, 2020, respectively, as well as organic growth across all channels as the business recovered from COVID-19 advertising lows in 2020.

Revenue ex-TAC increased $63.2 million, or 40%, for the year ended December 31, 2020 compared to the year ended December 31, 2019. The increase in Revenue ex-TAC was primarily attributable to contributions from the Telaria Merger, which was completed on April 1, 2020.

We expect Revenue ex-TAC to increase through the remainder of 2022 as compared to the same period in the prior year. We believe that CTV will be our biggest growth driver in future periods and continue to represent a higher percentage of our overall Revenue ex-TAC.

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss) adjusted to exclude stock-based compensation expense, depreciation and amortization, amortization of acquired intangible assets, impairment charges, interest income or expense, and other cash and non-cash based income or expenses that we do not consider indicative of our core operating performance, including, but not limited to foreign exchange gains and losses, acquisition and related items, non-operational real estate expense (income), net, and provision (benefit) for income taxes. We believe Adjusted EBITDA is useful to investors in evaluating our performance for the following reasons:

•Adjusted EBITDA is widely used by investors and securities analysts to measure a company’s performance without regard to items such as those we exclude in calculating this measure, which can vary substantially from company to company depending upon their financing, capital structures, and the method by which assets were acquired.

•Our management uses Adjusted EBITDA in conjunction with GAAP financial measures for planning purposes, including the preparation of our annual operating budget, as a measure of performance and the effectiveness of our business strategies, and in communications with our board of directors concerning our performance. Adjusted EBITDA may also be used as a metric for determining payment of cash incentive compensation.

•Adjusted EBITDA provides a measure of consistency and comparability with our past performance that many investors find useful, facilitates period-to-period comparisons of operations, and also facilitates comparisons with other peer companies, many of which use similar non-GAAP financial measures to supplement their GAAP results.

Although Adjusted EBITDA is frequently used by investors and securities analysts in their evaluations of companies, Adjusted EBITDA has limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of our results of operations as reported under GAAP. These limitations include:

•Stock-based compensation is a non-cash charge and will remain an element of our long-term incentive compensation package, although we exclude it as an expense when evaluating our ongoing operating performance for a particular period.

•Depreciation and amortization are non-cash charges, and the assets being depreciated or amortized will often have to be replaced in the future, but Adjusted EBITDA does not reflect any cash requirements for these replacements.

•Impairment charges are non-cash charges related to goodwill, intangible assets and/or long-lived assets.

•Adjusted EBITDA does not reflect non-cash charges related to acquisition and related items, such as amortization of acquired intangible assets, merger or acquisition related severance costs, and changes in the fair value of contingent consideration.

•Adjusted EBITDA does not reflect cash and non-cash charges and changes in, or cash requirements for, acquisition and related items, such as certain transaction expenses and expenses associated with earn-out amounts.

•Adjusted EBITDA does not reflect changes in our working capital needs, capital expenditures, non-operating real estate expenses or income, or contractual commitments.

•Adjusted EBITDA does not reflect cash requirements for income taxes and the cash impact of other income or expense.

•Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

Our Adjusted EBITDA is influenced by fluctuations in our revenue, cost of revenue, and the timing and amounts of the cost of our operations. Adjusted EBITDA should not be considered as an alternative to net income (loss), income (loss) from operations, or any other measure of financial performance calculated and presented in accordance with GAAP.

The following table presents a reconciliation of net income (loss), the most comparable GAAP measure, to Adjusted EBITDA for the years ended December 31, 2021, 2020, and 2019:

Other non-operating (income) expense, net (1) 15 —

Adjusted EBITDA increased by $105.6 million during the year ended December 31, 2021 compared to the year ended December 31, 2020, primarily due to increases in revenue from both organic growth and the SpotX and SpringServe Acquisitions, which are discussed in section "Comparison of the Years Ended December 31, 2021, 2020, and 2019" and improved operating leverage from our increased scale and related cost synergies.

Adjusted EBITDA increased by $17.4 million during the year ended December 31, 2020 compared to the year ended December 31, 2019, primarily due to the increase in revenue from the Telaria Merger and improved operating leverage from our increased scale and related merger cost synergies.

We expect Adjusted EBITDA to continue to increase as a result of continued growth in revenue, ongoing operating leverage, and the realization of additional cost synergies.

Liquidity and Capital Resources

Liquidity

At December 31, 2021, we had cash and cash equivalents of $230.4 million, of which $44.9 million was held in foreign currency denominated cash accounts, and an aggregate gross principal amount of $758.2 million of indebtedness outstanding under our Term Loan B Facility (as defined below) and our Convertible Senior Notes (as defined below). In addition, we are party to a $65.0 million Revolving Credit Facility, of which approximately $5.1 million is assigned to outstanding but undrawn letters of credit. See "Capital Resources" below for further information about our outstanding debt.

Our principal cash requirements for the 12 month period following this report primarily consist of personnel costs, contractual payment obligations, including office leases, data center costs and cloud hosting costs, capital expenditures, payment of interest and required principal payments on our Convertible Senior Notes and Term Loan B Facility, taxes, and cash requirements to fund working capital. In the longer term, we would expect to have similar cash requirements, with increases in absolute dollars associated with the continued growth of our business and expansion of operations. See "Contractual Obligations and Known Future Cash Requirements" for a further discussion of our known material contractual obligations.

Table of Contents

Our working capital needs and cash conversion cycle, which is influenced by seasonality and may be negatively impacted as a result of COVID-19, can have large fluctuations due to the timing of receipts from buyers and timing of disbursements to sellers. In addition, in the event a buyer defaults on payment, we may still be required to pay sellers for the inventory purchased. Additionally, our capital expenditure investments tend to be higher in the second half of the year. The impacts from changes in working capital and capital expenditures can significantly impact our cash flows and therefore, our liquidity during any period presented.

We have historically relied upon cash and cash equivalents, cash generated from operations, borrowings under credit facilities and issuance of debt for our liquidity needs. Our ability to meet our cash requirements depends on, among other things, our operating performance, competitive developments, and financial market conditions, all of which are significantly affected by business, financial, economic, political, global health-related and other factors, many of which we may not be able to control or influence.

We believe our existing cash and cash equivalents, cash generated from operating activities, and available borrowings under our Revolving Credit Facility will be sufficient to meet our working capital requirements for at least the next twelve months from the issuance of our financial statements. However, there are multiple factors that could impact our cash balances in the future, including the factors described above with respect to working capital and cash conversion cycles, as well as the duration and severity of the COVID-19 pandemic and its impact on buyers and sellers and the factors set forth in Part I, Item 1A: "Risk Factors" of this Annual Report on Form 10-K.

Capital Resources

On April 30, 2021, we completed the SpotX Acquisition, which included cash consideration of $640.0 million, and on July 1, 2021, we completed the SpringServe Acquisition, which included cash consideration of $31.1 million, excluding indemnification holdback.

In March 2021, we sold convertible senior notes ("Convertible Senior Notes") for gross proceeds of $400.0 million. The Convertible Senior Notes are senior, unsecured obligations with interest payable semi-annually in cash at a rate of 0.25% per annum in arrears on March 15 and September 15. The Convertible Senior Notes will mature on March 15, 2026, unless earlier converted, redeemed, or repurchased. The initial conversion rate is 15.6539 shares per $1,000 principal amount of notes, which represents an initial conversion price of approximately $63.88 per share of the Company’s common stock and is subject to adjustment as described in the Offering Memorandum. At December 31, 2021, the balance of the Convertible Senior Notes was $390.4 million, net of unamortized debt issuance costs of $9.6 million. Accrued interest for the Convertible Senior Notes at December 31, 2021 was $0.3 million.

In conjunction with the issuance of the Convertible Senior Notes, we entered into capped call transactions to reduce the Company's exposure to additional cash payments above principal balances in the event of a cash conversion of the Convertible Senior Notes. The Company may owe additional cash or shares to the holders of the Convertible Senior Notes upon early conversion if our stock price exceeds $91.260 per share, which is subject to certain adjustments. Although the Company’s incremental exposure to the additional cash payment above the principal amount of the Convertible Senior Notes is reduced by the capped calls, conversion of the Convertible Senior Notes by the holders may cause dilution to the ownership interests of existing stockholders. See Note 18 in the "Notes to Consolidated Financial Statements" for more information regarding terms and conditions of the Convertible Senior Notes and the capped call transactions.

On April 30, 2021, and in conjunction with the SpotX Acquisition, we entered into a credit agreement (the "Credit Agreement") with Goldman Sachs Bank USA as administrative and collateral agent, and other lending parties thereto for a $360.0 million seven-year senior secured term loan facility ("Term Loan B Facility") and a $52.5 million senior secured revolving credit facility (the "Revolving Credit Facility"), which was subsequently increased to $65.0 million in June 2021. As part of the Term Loan B Facility, the Company received $325 million in proceeds, net of discounts and fees, which were used to finance the SpotX Acquisition and related transactions and for general corporate purposes. At December 31, 2021, amounts available under the Revolving Credit Facility were $59.9 million, net of letters of credit outstanding in the amount of $5.1 million. Accrued interest for the Term Loan B Facility at December 31, 2021 was $1.8 million.

On December 13, 2021, the Board of Directors approved a share repurchase program, under which the company is authorized to purchase up to $50.0 million of its common stock over the twelve month period commencing December 10, 2021. The repurchase program allows the company to repurchase its common stock using open market stock purchases, privately negotiated transactions, block trades or other means in accordance with U.S. securities laws. Under the share repurchase program, 349,245 shares were purchased in open market purchases through December 31, 2021 for a total of approximately $6.0 million at an average of $17.20 per share. Approximately $44.0 million worth of shares remained available for purchase under the plan as of December 31, 2021.

In the future, we may attempt to raise additional capital through the sale of equity securities or through equity-linked or debt financing arrangements. If we raise additional funds by issuing equity or equity-linked securities, the ownership of our existing stockholders will be diluted. If we raise additional financing by incurring indebtedness, we will be subject to increased fixed payment obligations and could also be subject to restrictive covenants, such as limitations on our ability to incur additional debt, and

56

Table of Contents

other operating restrictions that could adversely impact our ability to conduct our business. Any future indebtedness we incur may result in terms that could be unfavorable to equity investors.

An inability to raise additional capital could adversely affect our ability to achieve our business objectives. In addition, if our operating performance during the next twelve months is below our expectations, our liquidity and ability to operate our business could be adversely affected.

Our cash and cash equivalents balance is affected by our results of operations, the timing of capital expenditures which are typically greater in the second half of the year, and by changes in our working capital, particularly changes in accounts receivable and accounts payable. The timing of cash receipts from buyers and payments to sellers can significantly impact our cash flows from operating activities and our liquidity for, and within, any period presented. Our collection and payment cycle can vary from period to period depending upon various circumstances, including seasonality, and may be negatively impacted as a result of COVID-19.

Cash Flows

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

Year Ended

(in thousands)

Cash flows provided by (used in) financing activities 678,053 7,354 (205)

Change in cash, cash equivalents and restricted cash $ 112,962 $ 28,843 $ 8,436

Operating Activities

Our cash flows from operating activities are primarily driven by revenues generated from advertising activity, offset by the cash costs of operations, and are significantly influenced by the timing of and fluctuations in receipts from buyers and related payments to sellers. Our future cash flows will be diminished if we cannot increase our revenue levels and manage costs appropriately.

During the year ended December 31, 2021, net cash provided by operating activities was $126.6 million, compared to net cash used in operating activities of $12.1 million during the year ended December 31, 2020 and net cash provided by operating activities of $32.0 million during the year ended December 31, 2019. Our operating activities included net income of $0.1 million, and net losses of $53.4 million, and $25.5 million for the years ended December 31, 2021 and 2020, and 2019, respectively, which were offset by non-cash adjustments of $94.6 million, $76.4 million, and $51.5 million, respectively. Net changes in our working capital resulted in increases of $31.9 million and $5.9 million in cash provided by operating activities in 2021 and 2019, respectively. In 2020, net changes in our working capital increased cash used from operating activities by $35.1 million. The net changes in working capital for all periods presented are primarily due to the timing of cash receipts from buyers and the timing of payments to sellers.

We believe that cash flows from operations will continue to fluctuate, but in general will increase over time as our business continues to grow.

Investing Activities

Our primary investing activities have consisted of acquisitions of businesses, purchases of property and equipment, capital expenditures in support of creating and enhancing our technology infrastructure, and investments in, and maturities of, available-for-sale securities. Purchases of property and equipment and investments in internal use software development may vary from period-to-period due to the timing of the expansion of our operations, changes to headcount, and the cycles of our internal use software development. We anticipate investment in internal use software development to slightly increase compared to past years' investment levels as we continue to innovate new solutions on our platform. As the business continues to grow, we expect our investment in property and equipment to increase compared to 2021. Historically, a majority of our purchases in property and equipment have occurred in the latter half of the year in preparation for the peak volumes of the fourth quarter and early in the first quarter of the following year. We expect those trends to continue, with higher levels of property and equipment spend in the latter half of next year compared to the first half of the year. Investments in, and maturities of, available-for-sale securities and acquisitions of businesses vary from period-to-period.

During the year ended December 31, 2021, net cash used by investing activities was $691.0 million compared to net cash provided by investing activities of $32.6 million during the year ended December 31, 2020 and net cash used by investing activities of $23.4 million during the year ended December 31, 2019. During the year ended December 31, 2021, 2020, and 2019, we used

57

Table of Contents

cash for purchases of property and equipment of $17.7 million, $14.3 million, and $11.4 million, respectively, and used cash for investments in our internally developed software of $11.4 million, $7.7 million, and $8.5 million, respectively. During the year ended December 31, 2021, we used net cash of $661.9 million to acquire SpotX, SpringServe, and Nth Party. During the year ended December 31, 2020, we acquired $54.6 million cash in the Telaria Merger. For the year ended December 31, 2019, we used net cash of $11.0 million for the acquisition of RTK.io and had net maturities of investments in available-for-sale securities of $7.5 million.

Financing Activities

Our financing activities consisted of our Convertible Senior Notes offering, amounts borrowed under our Term Loan B Facility, and transactions related to our equity plans. For the years ended December 31, 2021, 2020, and 2019 we provided net cash of $678.1 million and $7.4 million, and used net cash of $0.2 million, respectively, for financing activities. Cash inflows from financing activities for the year ended December 31, 2021 included $400.0 million in proceeds from our Convertible Senior Notes offering, $349.2 million in net proceeds from our Term Loan B Facility, cash proceeds from stock options exercised of $9.4 million and $3.7 million cash proceeds from issuance of common stock under our employee stock purchase plan. These inflows for the year ended December 31, 2021 were partially offset by a $39.0 million payment for capped call transactions entered into in connection with the Convertible Senior Notes offering, debt issuance cost payments of $30.4 million, repurchases of $6.0 million of treasury stock in conjunction with our stock repurchase plan, $6.5 million for income tax deposits paid in respect of vesting of stock-based compensation awards that were reimbursed by the award recipients through surrender of shares, $1.8 million repayment of Term Loan B, and repayment of $0.6 million financing lease obligations. Cash inflows from financing activities for the year ended December 31, 2020 included cash proceeds from stock option exercised of $13.5 million and cash proceeds from issuance of common stock under our employee stock purchase plan of $1.7 million, partially offset by payments of $7.9 million for income tax deposits paid in respect of vesting of stock-based compensation awards that were reimbursed by the award recipients through surrender of shares. Cash outflows from financing activities for the year ended December 31, 2019 included payments of $1.8 million for income tax deposits paid in respect of vesting of stock-based compensation awards that were reimbursed by the award recipients through surrender of shares, which were partially offset by cash proceeds from issuance of common stock under our employee stock purchase plan of $1.1 million and cash proceeds from stock option exercised of $0.6 million.

Off-Balance Sheet Arrangements

We do not have any relationships with other entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities that have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. We did not have any other off-balance sheet arrangements at December 31, 2021 other than the short-term operating leases and the indemnification agreements described below, and commitments mentioned in Note 17 - Commitments and Contingencies.

Contractual Obligations and Known Future Cash Requirements

Our principal commitments consist of obligations under our Convertible Senior Notes, Term Loan B Facility, Revolving Credit Facility, leases for our various office facilities, including our corporate headquarters in New York, New York and offices in Los Angeles, California, operating lease agreements, including data centers and cloud hosting services that expire at various times through 2031, and indemnification holdback associated with the SpringServe Acquisition. In certain cases, the terms of the lease agreements provide for rental payments on a graduated basis.

We received rental income from subleases totaling $4.4 million for the year ended December 31, 2021.

The following table summarizes our future lease obligations, payments of principal and interest under our debt agreements, sublease income, and other future payments due under non-cancelable agreements at December 31, 2021.

58

Table of Contents

(in thousands)

Payments associated with our Convertible Senior Notes are based on contractual terms and intended timing of repayments of long-term debt and associated interest and do not assume conversion prior to the maturity date.

Other non-cancelable obligations include other agreements in the normal course of business and purchase consideration that extend beyond a year.

In the ordinary course of business, we enter into agreements with sellers, buyers, and other third parties pursuant to which we agree to indemnify buyers, sellers, vendors, lessors, business partners, lenders, stockholders, and other parties with respect to certain matters, including, but not limited to, losses resulting from claims of intellectual property infringement, damages to property or persons, business losses, or other liabilities. Generally, these indemnity and defense obligations relate to our own business operations, obligations, and acts or omissions. However, under some circumstances, we agree to indemnify and defend contract counterparties against losses resulting from their own business operations, obligations, and acts or omissions, or the business operations, obligations, and acts or omissions of third parties. These indemnity provisions generally survive termination or expiration of the agreements in which they appear. In addition, we have entered into indemnification agreements with our directors, executive officers and certain other officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers, or employees. No demands for indemnification have been made as of December 31, 2021.

Critical Accounting Policies and Estimates

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

We believe that the following assumptions and estimates have the greatest potential impact on our consolidated financial statements: (i) the determination of revenue recognition as net versus gross in our revenue arrangements, (ii) the determination of the estimated useful lives of internal-use software development costs, (iii) the recoverability of intangible asset and goodwill, (iv) assumptions used in the valuation models to determine the fair value of stock options, awards with market and performance conditions and stock-based compensation expense, (v) the assumptions used in the valuation of acquired assets and liabilities in business combinations, and (vi) income taxes, including the realization of tax assets and estimates of tax liabilities. There have been no significant changes in our accounting policies or estimates from those disclosed in our audited consolidated financial statements and notes thereto for the years ended December 31, 2021, 2020 and 2019.

We believe that the accounting policies disclosed below include estimates and assumptions critical to our business and their application could have a material impact on our consolidated financial statements. In addition to these critical policies, our significant accounting policies are included within Note 2 of our "Notes to Consolidated Financial Statements" within this Annual Report on Form 10-K.

Revenue Recognition

We generate revenue from transactions where we provide a platform for the purchase and sale of digital advertising inventory. Generally, our revenue is based on a percentage of the ad spend that runs through our platform, although for certain clients or transaction types we may receive a fixed CPM for each impression sold, and for advertising campaigns that are transacted through insertion orders we earn revenue based on the full amount of ad spend that runs through our platform. We also generate revenue from the fee we charge clients for use of our Demand Manager header-bidding product, and from our SpringServe ad server product, which we acquired on July 1, 2021. Our platform dynamically connects sellers and buyers of advertising inventory in a digital marketplace. Our solution incorporates proprietary machine-learning algorithms, sophisticated data processing, high-volume storage, detailed analytics capabilities, and a distributed infrastructure. Digital advertising inventory is created when consumers access sellers’ content. Sellers provide digital advertising inventory to our platform in the form of advertising requests, or ad requests. When we receive ad requests from sellers, we send bid requests to buyers, which enable buyers to bid on sellers’ digital advertising inventory. Winning bids can create advertising, or paid impressions, for the seller to present to the consumer.

The total volume of spending between buyers and sellers on our platform is referred to as advertising spend. We keep a percentage of that advertising spend as a fee, and remit the remainder to the seller. The fee that we retain from the gross advertising spend on our platform is recognized as revenue. The fee earned on each transaction is based on the pre-existing agreement we have with the seller and the clearing price of the winning bid. We recognize revenue upon fulfillment of our performance obligation to a client, which occurs at the point in time an ad renders and is counted as a paid impression, subject to a contract existing with the client and a fixed or determinable transaction price. Performance obligations for all transactions are satisfied, and the corresponding revenue is recognized, at a distinct point in time. We have no arrangements with multiple performance obligations. We consider the following when determining if a contract exists (i) contract approval by all parties, (ii) identification of each party’s rights regarding the goods or services to be transferred, (iii) specified payment terms, (iv) commercial substance of the contract, and (v) collectability of substantially all of the consideration is probable.

The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether we are acting as the principal or an agent in the transaction. In determining whether we are acting as the principal or an agent, we followed the accounting guidance for principal-agent considerations. Making such determinations involves judgment and is based on an evaluation of the terms of each arrangement, none of which are considered presumptive or determinative.

For the majority of transactions on our platform, we have determined that we do not act as the principal in the purchase and sale of digital advertising inventory because we are not the primary obligor as we do not have control of the digital advertising inventory and do not set prices agreed upon within the auction marketplace, and therefore we report revenue on a net basis. However, for certain transactions related to revenue streams acquired in connection with the Telaria Merger and the SpotX Acquisition, we report revenue on a gross basis, based primarily on our determination that we act as the primary obligor in the delivery of advertising campaigns for buyers with respect to such transactions.

Internal Use Software Development Costs

We capitalize certain internal use software development costs associated with creating and enhancing internally developed software related to our technology infrastructure. These costs include personnel and related employee benefits expenses for employees who are directly associated with and who devote time to software projects, and external direct costs of materials and services consumed in developing or obtaining the software. Software development costs that do not meet the qualification for capitalization, as further discussed below, are expensed as incurred and recorded in technology and development expenses in the results of operations.

Software development activities generally consist of three stages, (i) the planning stage, (ii) the application and infrastructure development stage, and (iii) the post implementation stage. Costs incurred in the planning and post implementation stages of software development, including costs associated with the post-configuration training and repairs and maintenance of the developed technologies, are expensed as incurred. We capitalize costs associated with software developed for internal use when the planning stage is completed, management has authorized further funding for the completion of the project, and it is probable that the project will be completed and perform as intended. Costs incurred in the application and infrastructure development stages, including significant enhancements and upgrades, are capitalized. Capitalization ends once a project is substantially complete and the software and technologies are ready for their intended purpose.

We amortize internal use software development costs using a straight-line method over a three year estimated useful life, commencing when the software is ready for its intended use. The straight-line recognition method approximates the manner in which the expected benefit will be derived. We determined the life of internal use software based on historical software upgrades and replacement. The Company evaluates internal use software in use for abandonment and use that as a significant indicator for impairment on a quarterly basis.

Valuation of Goodwill and Intangibles

The valuation of assets acquired in a business combination and asset impairment reviews require the use of significant estimates and assumptions. The acquisition method of accounting for business combinations requires us to estimate the fair value of

60

Table of Contents

assets acquired, liabilities assumed, and any noncontrolling interest in an acquired business to properly allocate purchase price consideration between assets that are depreciated or amortized and goodwill.

Long-lived assets, including property and equipment, long-term prepayments, and intangible assets, excluding goodwill, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The evaluation is performed at the lowest level of identifiable cash flows independent of other assets. An impairment loss would be recognized when estimated undiscounted future cash flows generated from the assets are less than their carrying amount. Measurement of an impairment loss would be based on the excess of the carrying amount of the asset group over its fair value.

We evaluate goodwill annually or more frequently if events or changes in circumstances indicate that goodwill may be impaired. In accordance with guidance related to impairment testing, we have the option to first assess qualitative factors to determine whether or not it is necessary to perform the quantitative goodwill impairment test. If the qualitative assessment option is not elected, or if the qualitative assessment indicates that it is more likely than not that the fair value is less than its carrying amount, a quantitative analysis is then performed. The quantitative analysis, if performed, compares the estimated fair value of the Company with its respective carrying amount, including goodwill. If the estimated fair value of the Company exceeds its carrying amount, including goodwill, goodwill is considered not to be impaired and no additional steps are necessary. If the fair value is less than the carrying amount, including goodwill, then an impairment adjustment must be recorded up to the carrying amount of goodwill.

Stock-Based Compensation

Compensation expense related to employee and non-employee stock-based awards is measured and recognized on the fair value of the awards granted. We have granted awards to employees that vest based solely on continued service, or service conditions, awards that vest based on the achievement of performance targets, or performance conditions, and awards that vest based on our stock price exceeding a peer index, or market conditions. The fair value of each option award containing service and/or performance conditions is estimated on the grant date using the Black-Scholes option-pricing model. The fair value of awards containing market conditions is estimated using a Monte-Carlo lattice model. For service condition awards, stock-based compensation expense is recognized on a straight-line basis over the requisite service periods of the awards, which is generally four years. For performance condition and market condition awards, stock-based compensation expense is recognized using a graded vesting model over the requisite service period of the awards. For market condition awards, expense recognized is not subsequently reversed if the market conditions are not achieved.

Determining the fair value of stock-based awards at the grant date requires judgment. Our use of the Black-Scholes option-pricing model and Monte-Carlo lattice model requires the input of subjective assumptions such as the expected term of the option, the expected volatility of the price of our common stock, risk-free interest rates, the expected dividend yield of our common stock, and the fair value of our common stock. The assumptions used in our valuation models represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, our stock-based compensation expense could be materially different in the future.

Business Combinations

The results of businesses acquired in a business combination are included in our consolidated financial statements from the date of acquisition. We allocate the purchase price of a business combination, which is the sum of the consideration provided, which may consist of cash, equity or a combination of the two, to the identifiable assets and liabilities of the acquired business at their acquisition date fair values. The excess of the purchase price over the amount allocated to the identifiable assets and liabilities, if any, is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, estimates of future revenues and cash flows, discount rates and selection of comparable companies.

When we issue stock-based or cash awards to an acquired company’s stockholders, we evaluate whether the awards are contingent consideration or compensation for post-business combination services. The evaluation includes, among other things, whether the vesting of the awards is contingent on the continued employment of the selling stockholder beyond the acquisition date. If continued employment is required for vesting, the awards are treated as compensation for post-acquisition services and recognized as expense over the requisite service period.

We estimate the fair value of intangible assets acquired generally using a discounted cash flow approach, which includes an analysis of the future cash flows expected to be generated by the asset and the risk associated with achieving these cash flows. The key assumptions used in the discounted cash flow model include the discount rate that is applied to the forecasted future cash flows to calculate the present value of those cash flows and the estimate of future cash flows attributable to the acquired intangible asset, which include revenue, expenses and taxes. The carrying value of acquired working capital assets and liabilities approximates its fair value, given the short-term nature of these assets and liabilities.

Income Taxes

We are subject to income taxes in the U.S. and foreign jurisdictions. Significant judgment is required in evaluating our uncertain tax positions and determining our provision for income taxes.

Although we believe we have adequately reserved for our uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be different. We adjust these reserves as facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes and the effective tax rate in the period in which such determination is made.

The provision for income taxes includes the effect of reserve provisions and changes to reserves that are considered appropriate as well as the related net interest and penalties. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Services ("IRS") and other tax authorities which may assert assessments against us. We regularly assess the likelihood of adverse outcomes resulting from these examinations and assessments to determine the adequacy of our provision for income taxes.

Recently Issued Accounting Pronouncements

The information set forth under Note 2 to our "Notes to Consolidated Financial Statements" under the caption "Organization and Summary of Significant Accounting Policies" is incorporated herein by reference.

Item 7A. Quantitative and Qualitative Disclosure About Market Risk

We have operations both in the United States and internationally, and we are exposed to market risks in the ordinary course of our business. These risks include primarily interest rate, foreign exchange, and inflation risks. The risks below may be further exacerbated by the effects of the COVID-19 pandemic on global macroeconomic and market conditions.

Interest Rate Fluctuation Risk

Our cash and cash equivalents consist of cash and money market funds, but may from time to time also include commercial paper, with original maturities of three months or less. Our investments may consist of repurchase agreements, U.S. government agency debt, and U.S. treasury debt. The primary objective of our investment activities is to preserve the value of our cash without significantly increasing risk. Because our cash, cash equivalents, and investments have a short maturity, our portfolio’s fair value is relatively insensitive to interest rate changes, however, interest income earned will vary as interest rates change.

We do not have economic interest rate expense exposure on our Convertible Senior Notes due to their fixed interest rate nature. The amount paid upon redemption is not based on changes in any index or changing market rates. It is fixed at 100% of the principal amount of the Convertible Senior Notes plus unpaid interest. Since the Convertible Senior Notes bear fixed rate coupon, we are not exposed to interest rate risk on those notes, however, the fair value of those notes will change as market interest rates change.

We have a Term Loan B Facility under the Credit Agreement which bears a floating rate of interest that resets periodically, subject to a 0.75% floor on that floating rate, according to the terms of the agreement. Our financial results would be exposed to potential changes in the underlying base interest rate on that debt ifthe underlying base interest rate were to reset above the floor on such underlying interest rate. Similarly, the fair value of Term Loan B Facility may fluctuate when the underlying base interest rate fluctuates below the floor. As of December 31, 2021, the Company had no outstanding borrowings under the Revolving Credit Facility. Should the company borrow under the Revolving Credit Facility at any point in the future, any associated borrowings would have a floating underlying base rate of interest that would expose the Company to interest rate risk.

We do not believe that an increase or decrease in interest rates of 100 basis points would have a material effect on our operating results or financial condition. The annualized impact to interest expense for each 100 basis points increase above the LIBOR Floor on our Term Loan B Facility is approximately $3.6 million. The actual impact to our financial results of the same increase in interest rates is expected to be lower than $3.6 million depending on the timing and magnitude of such rate changes relative to our LIBOR Floor, and will be partially offset by higher interest income earned on our cash and cash equivalent balances over the same period. In future periods, we will continue to evaluate our investment policy relative to our overall objectives. With regard to all debt currently outstanding, the company is potentially exposed to refinancing risk, should the Company seek to refinance or raise debt in the future, and the prevailing price or terms for debt differs from terms in our current debt agreements.

Foreign Currency Exchange Risk

We have foreign currency risks related to our revenue and expenses denominated in currencies other than the U.S. Dollar, principally the British Pound, Australian Dollar, Canadian Dollar and Euro. The volatility of exchange rates depends on many factors that we cannot forecast with reliable accuracy. We have experienced and will continue to experience fluctuations in our net

income (loss) as a result of transaction gains and losses related to translating certain cash balances, trade accounts receivable and payable balances and intercompany balances that are denominated in currencies other than the U.S. Dollar. The effect of an immediate 10% adverse change in foreign exchange rates on foreign-denominated accounts at December 31, 2021, including intercompany balances, would result in a foreign currency loss of approximately $6.2 million. In the event our non-U.S. Dollar denominated sales and expenses increase, our operating results may be more greatly affected by fluctuations in the exchange rates of the currencies in which we do business. At this time we do not, but we may in the future, enter into derivatives or other financial instruments in an attempt to hedge our foreign currency exchange risk. It is difficult to predict the impact hedging activities would have on our results of operations.

Inflation Risk

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Magnite, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Magnite, Inc. and subsidiaries (the "Company") as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive loss, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2021 and the related notes (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

As described in Management’s Report on Internal Control over Financial Reporting, management excluded from its assessment of internal control over financial reporting certain elements related to SpotX, Inc. which was acquired on April 30, 2021. The excluded elements of the SpotX business represented approximately 34% of the Company’s revenues and 10% of the Company’s total assets as of and for the year ended December 31, 2021. Accordingly, our audit did not include the internal control over financial reporting for certain elements related to SpotX, Inc.

Basis for Opinions

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

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

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to 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. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

65

Table of Contents

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

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Business Combinations – SpotX, Inc. Acquisition– Technology, Customer Relationships, and Backlog Intangible Assets — Refer to Note 10 to the financial statements

Critical Audit Matter Description

On April 30, 2021, the Company completed its acquisition of SpotX, Inc. for a purchase price of $1.2 billion, consisting of $640.0 million in cash plus 12,374,315 shares of the Company’s common stock ($495.6 million based on the fair value of the Company's common stock on April 30, 2021). The Company accounted for the acquisition using the acquisition method of accounting for business combinations and the fair value of the purchase price of $1.2 billion was allocated to the assets acquired and liabilities assumed based on their respective fair values, including the technology, customer relationships, and backlog intangible assets of $280.4 million, $130.3 million, and $11.1 million, respectively. Management estimated the fair value of the technology, customer relationships, and backlog intangible assets using a discounted cash flow approach, which included an analysis of future cash flows expected to be generated by each intangible asset. The fair value of the acquired technology and backlog was valued using The Excess Earnings Method. The Company used the Loss‐of‐Revenue and Income Method in its valuation of the existing Customer Relationships. The fair value determination of these intangible assets required management to make significant, subjective estimates and assumptions related to forecasted future cash flows and the selected discount rate.

We identified the aforementioned intangible assets as a critical audit matter because of the significant estimates and assumptions management makes to determine the fair value of these intangible assets. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the forecasts of future cash flows and the selection of the discount rate for the technology, customer relationships, and backlog intangible assets included the following, among others:

•We tested the effectiveness of controls over the valuation of intangible assets, including management’s controls over forecasts of future cash flows and the determination of the discount rate.

•We assessed the reasonableness of management’s forecasts of future cash flows by comparing the revenue and disaggregated cost projections to historical results, certain peer companies, third-party industry forecasts, as well as performing inquiries with certain members of management.

•With the assistance of our fair value specialists, we evaluated the valuation methodology used to determined fair value along with the reasonableness of the discount rate including independently estimating the discount rate using a process consistent with generally accepted valuation practices.

•We evaluated whether the estimated future cash flows were consistent with evidence obtained in other areas of the audit.

Business Combinations – SpringServe, LLC Acquisition– Technology Intangible Asset — Refer to Note 10 to the financial statements

Critical Audit Matter Description

On July 1, 2021, the Company completed its acquisition of SpringServe, LLC through the Company's wholly-owned subsidiary, SpotX, pursuant to a definitive agreement entered into on July 1, 2021. As a result of the acquisition, SpringServe has become a wholly-owned subsidiary of SpotX, and a wholly-owned indirect subsidiary of the Company. The purchase price was approximately $31.1 million in cash, pursuant to a previously negotiated option agreement that the Company secured as part of the SpotX Acquisition. At the time of the Company’s acquisition of SpotX, the fair value of SpotX's minority investment and purchase right were valued at a combined $9.5 million. In connection with the SpringServe Acquisition, approximately $1.4 million of the purchase price was held back to cover possible indemnification claims, which is expected to be paid in cash one year after the

66

Table of Contents

acquisition. The Company accounted for the acquisition using the acquisition method of accounting for business combinations and the fair value of the total purchase price of $42.1 million was allocated to the assets acquired and liabilities assumed based on their respective fair values, including the technology intangible asset of $15.5 million. Management estimated the fair value of the technology intangible asset using a discounted cash flow approach, which included an analysis of future cash flows expected to be generated by the intangible asset. The fair value of the acquired technology was valued using the Excess Earnings Method. The fair value determination of this intangible asset required management to make significant, subjective estimates and assumptions related to forecasted future cash flows and the selected discount rate.

We identified the aforementioned intangible asset as a critical audit matter because of the significant estimates and assumptions management makes to determine the fair value of this intangible asset. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the forecasts of future cash flows and the selection of the discount rate for the technology intangible asset included the following, among others:

•We tested the effectiveness of controls over the valuation of intangible assets, including management’s controls over forecasts of future cash flows and the determination of the discount rate.

•We assessed the reasonableness of management’s forecasts of future cash flows by comparing the revenue and disaggregated cost projections to historical results, certain peer companies, third-party industry forecasts, as well as performing inquiries with certain members of management.

•With the assistance of our fair value specialists, we evaluated the valuation methodology used to determined fair value along with the reasonableness of the discount rate including independently estimating the discount rate using a process consistent with generally accepted valuation practices.

•We evaluated whether the estimated future cash flows were consistent with evidence obtained in other areas of the audit.

Revenue — Highly Automated Systems to Process and Record Revenue - Refer to Note 4 to the financial statements.

Critical Audit Matter Description

The Company’s revenue consists of transaction-based fees and is made up of a significant volume of low-dollar transactions, sourced from multiple systems, databases, and other tools. Due to the fact that revenue transactions do not consist of the transfer of physical goods but are derived from the purchase and sale of digital advertising inventory through their platform and related systems, the processing and recording of revenue is highly automated and is based on contractual terms with advertisers and publishers. Because of the nature of the Company’s transaction-based fees, the Company uses automated systems to process and record its revenue transactions.

We identified revenue as a critical audit matter because the of the information technology (IT) -dependent nature of the Company’s revenue stream and the significant audit effort required in performing our audit procedures, including involvement of professionals with expertise in IT to identify, test, and evaluate the Company’s systems, software applications, and automated controls related to the revenue cycle.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to certain of the Company’s systems to process revenue transactions included the following, among others:

•With the assistance of our IT specialists, we:

◦Identified the significant systems used to process revenue transactions and tested the effectiveness of general IT controls over the systems, including testing of user access controls, change management controls, and IT operations controls.

◦We tested the effectiveness of system interface controls and automated controls within the revenue process, as well as controls designed to ensure the accuracy and completeness of revenue.

◦For the relevant platform systems, in order to test that transactions are being processed and recorded completely and accurately, we independently created test impressions and traced them through the systems to final output for financial reporting.

•We tested the effectiveness of certain controls within the relevant revenue business processes, including those in place to reconcile the various systems to the Company’s general ledger.

67

Table of Contents

•We tested revenue through the use of data analytics in order to:

◦Evaluate recorded revenue and revenue trends

◦Identify significant relationships in the revenue population

◦Sufficiently understand identified significant relationships and related accounts affecting revenue.

•We performed audit procedures on those related accounts determined to have a significant relationship with revenue. Such procedures included sending confirmations to customers for a selection of accounts receivable and making selections of cash receipts subsequent to year end and tracing them back to their associated invoices included in accounts receivable as of the balance sheet date. We also performed a combination of audit procedures on publisher payables, which included subsequent disbursements testing, recalculations of selected publisher payable amounts, and substantive analytical procedure over publisher payables balances as of the balance sheet date.

Debt and Additional Paid-In Capital –Accounting for Convertible Senior Notes and Capped Call Transactions — Refer to Note 18 to the financial statements

Critical Audit Matter Description

In March 2021, the Company issued $400.0 million aggregate principal amount of 0.25% convertible senior notes in a private placement, including $50.0 million aggregate principal amount of such notes pursuant to the exercise in full of the over-allotment options of the initial purchasers (collectively, the “Convertible Senior Notes”). The Convertible Senior Notes will mature on March 15, 2026, unless earlier repurchased, redeemed or converted. The Company used approximately $39.0 million of the net proceeds from the offering to pay for the Capped Call Transactions.

We identified the accounting for the Convertible Senior Notes and Capped Call Transactions as a critical audit matter due to the complexity involved and the management judgment necessary to determine the accounting for the Convertible Senior Notes and Capped Call Transactions within the financial statements. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve professionals having expertise in accounting for complex financial instruments, when performing audit procedures to evaluate management’s judgments and conclusions.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the accounting for the Convertible Senior Notes and Capped Call Transactions included the following, among others:

a.We tested the effectiveness of controls over management’s accounting treatment for the Convertible Senior Notes and Capped Call Transactions.

b.We read and analyzed the Convertible Senior Notes and Capped Call agreements to evaluate the accounting treatment for the convertible senior notes and capped call transactions.

c.With the assistance of professionals having expertise in accounting for complex financial instruments, we evaluated management’s conclusion that the Convertible Senior Notes should be recorded in debt and the Capped Call Transactions should be recorded in additional paid-in capital.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Nature of Operations

Company Overview

Magnite, Inc. ("Magnite" or the "Company"), formerly known as The Rubicon Project, Inc., was formed in Delaware and began operations on April 20, 2007. On April 1, 2020, Magnite completed a stock-for-stock merger with Telaria, Inc., ("Telaria" and such merger the "Telaria Merger"), a leading sell side advertising platform and provider of connected television ("CTV") technology. On April 30, 2021, the Company completed its acquisition of SpotX, Inc. ("SpotX" and such acquisition the "SpotX Acquisition"), a leading CTV and video advertising platform. On July 1, 2021, the Company completed its acquisition of SpringServe, LLC ("SpringServe" and such acquisition the "SpringServe Acquisition"), a leading ad serving platform for CTV. The Company operates a sell side advertising platform that offers buyers and sellers of digital advertising a single partner for transacting globally across all channels, formats, and auction types.

On June 8, 2020, the Company voluntarily delisted its common stock from the New York Stock Exchange ("NYSE") and commenced listing on The Nasdaq Global Select Market of The Nasdaq Stock Market LLC ("Nasdaq"). On June 30, 2020, the Company changed its name from "The Rubicon Project, Inc." to "Magnite, Inc." In connection with the name change, the Company also changed its ticker symbol from "RUBI" to "MGNI." Magnite has its principal offices in New York City, Los Angeles, London, and Sydney, and additional offices in Europe, Asia, North America, and South America.

The Company provides a technology solution to automate the purchase and sale of digital advertising inventory for buyers and sellers. The Company's platform features applications and services for sellers of digital advertising inventory, or publishers, that own or operate websites, applications, CTV channels, and other digital media properties, to manage and monetize their inventory; applications and services for buyers, including advertisers, agencies, agency trading desks, and demand side platforms, to buy digital advertising inventory; and a transparent, independent marketplace that brings buyers and sellers together and facilitates intelligent decision making and automated transaction execution at scale. The Company's clients include many of the world's leading sellers and buyers of digital advertising inventory.

Sellers monetize their inventory through the Company’s platform by seamlessly connecting to a global market of integrated buyers that transact through real-time bidding, which includes direct sale of premium inventory to a buyer, referred to as private marketplace, and open auction bidding, where buyers bid against each other in a real-time auction for the right to purchase a publisher’s inventory, referred to as open marketplace. At the same time, buyers leverage the Company’s platform to manage their advertising spending and reach their target audiences, simplify order management and campaign tracking, obtain actionable insights into audiences for their advertising, and access impression-level purchasing from thousands of sellers.

Note 2—Organization and Summary of Significant Accounting Policies

Basis of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, and include the operations of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.

Segments

Management has determined that the Company operates as one segment. The Company’s chief operating decision maker reviews financial information on an aggregated and consolidated basis, together with certain operating and performance measures principally to make decisions about how to allocate resources and to measure the Company’s performance.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported and disclosed financial statements and accompanying footnotes. Due to the economic uncertainty as a result of the COVID-19 pandemic, it has become more difficult to apply certain assumptions and judgments into these estimates. The extent of the impact of COVID-19 pandemic on the Company's operational and financial performance will depend on future developments, which are highly uncertain and cannot be predicted, including but not limited to, the duration and spread of the pandemic, its severity, including any resurgence, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. During the year ended December 31, 2021, this uncertainty continued to result in a higher level of judgement related to its estimates and assumptions. As of the date of issuance of

75

Table of Contents

the consolidated financial statements, the Company is not aware of any specific event or circumstance that would require the Company to update its estimates, judgments, or revise the carrying value of its assets or liabilities. These estimates may change, as new events occur and additional information is obtained, and are recognized in the consolidated financial statements as soon as they become known. Actual results could differ materially from these estimates.

On an ongoing basis, management evaluates its estimates, primarily those related to: (i) revenue recognition criteria, including the determination of revenue reporting as net versus gross in the Company’s revenue arrangements, (ii) accounts receivable and allowances for doubtful accounts, (iii) the useful lives of intangible assets, internal use software development costs, and property and equipment, (iv) valuation of long-lived assets and their recoverability, including goodwill, (v) the realization of tax assets and estimates of tax liabilities, (vi) assumptions used in valuation models to determine the fair value of stock-based awards, (vii) fair value of financial instruments, (viii) the recognition and disclosure of contingent liabilities, and (ix) the assumptions used in valuing acquired assets and assumed liabilities in business combinations.

These estimates are based on historical data and experience, as well as various other factors that management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Estimates relating to the estimated useful lives of internal-use software development costs, assumptions used in the valuation models to determine the fair value of stock options and stock-based compensation expense, business combinations, estimated useful lives of long-lived assets, recoverability of intangible assets and goodwill, the assumptions used in the valuation of acquired assets and liabilities in business combinations, and income taxes, including the realization of tax assets and estimates of tax liabilities. require the selection of appropriate valuation methodologies and models, and significant judgment in evaluating ranges of assumptions and financial inputs. Actual results may differ materially from those estimates under different assumptions or circumstances.

Revenue Recognition

The Company generates revenue from transactions where it provides a platform for the purchase and sale of digital advertising inventory. Generally, our revenue is based on a percentage of the ad spend that runs through our platform, although for certain clients or transaction types we may receive a fixed CPM for each impression sold, and for advertising campaigns that are transacted through insertion orders we earn revenue based on the full amount of ad spend that runs through our platform. The Company also generates revenue from the fee it charges clients for use of its Demand Manager header-bidding product and SpringServe ad server product, which we acquired on July 1, 2021. The Company's platform dynamically connects sellers and buyers of advertising inventory in a digital marketplace. The Company's solution incorporates proprietary machine-learning algorithms, sophisticated data processing, high-volume storage, detailed analytics capabilities, and a distributed infrastructure.Digital advertising inventory is created when consumers access sellers’ content. Sellers provide digital advertising inventory to the Company's platform in the form of advertising requests, or ad requests. When the Company receives ad requests from sellers, it sends bid requests to buyers, which enable buyers to bid on sellers’ digital advertising inventory. Winning bids can create advertising, or paid impressions, for the seller to present to the consumer.

The total volume of spending between buyers and sellers on the Company's platform is referred to as advertising spend. The Company keeps a percentage of that advertising spend as a fee, and remits the remainder to the seller. The fee that the Company retains from the gross advertising spend on its platform is recognized as revenue. The fee earned on each transaction is based on the pre-existing agreement between the Company and the seller and the clearing price of the winning bid. The Company recognizes revenue upon fulfillment of its performance obligation to a client, which occurs at the point in time an ad renders and is counted as a paid impression, subject to a contract existing with the client and a fixed or determinable transaction price. The Company does not have arrangements with multiple performance obligations. The Company considers the following when determining if a contract exists (i) contract approval by all parties, (ii) identification of each party’s rights regarding the goods or services to be transferred, (iii) specified payment terms, (iv) commercial substance of the contract, and (v) collectability of substantially all of the consideration is probable.

The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether the Company is acting as the principal or an agent in the transaction. In determining whether the Company is acting as the principal or an agent, the Company follows the accounting guidance for principal-agent considerations. Making such determinations involves judgment and is based on an evaluation of the terms of each arrangement, none of which are considered presumptive or determinative.

Expenses

The Company classifies its expenses into the following categories:

Cost of Revenue. The Company's cost of revenue consists primarily of data center costs, bandwidth costs, ad protection

76

Table of Contents

costs, depreciation and maintenance expense of hardware supporting the Company's revenue-producing platform, amortization of software costs for the development of the Company's revenue-producing platform, amortization expense associated with acquired developed technologies, personnel costs, facilities-related costs, and cloud computing costs. In addition, for revenue booked on a gross basis, cost of revenue includes traffic acquisition costs. Personnel costs included in cost of revenue include salaries, bonuses, and stock-based compensation, and are primarily attributable to personnel in the Company's network operations group who support the Company's platform. The Company capitalizes costs associated with software that is developed or obtained for internal use and amortizes the costs associated with its revenue-producing platform in cost of revenue over their estimated useful lives. The Company amortizes acquired developed technologies over their estimated useful lives.

Sales and Marketing. The Company's sales and marketing expenses consist primarily of personnel costs, including salaries, bonuses, and stock-based compensation, as well as marketing expenses such as brand marketing, travel expenses, trade shows and marketing materials, professional services, and amortization expense associated with client relationships and backlog from the Company's business acquisitions and, to a lesser extent, facilities-related costs and depreciation and amortization. The Company's sales organization focuses on increasing the adoption of the Company's solution by existing and new buyers and sellers. The Company amortizes acquired intangibles associated with client relationships and backlog from its business acquisitions over their estimated useful lives.

Technology and Development. The Company's technology and development expenses consist primarily of personnel costs, including salaries, bonuses, and stock-based compensation, and professional services associated with the ongoing development and maintenance of the Company's solution, depreciation and amortization, and, to a lesser extent, facilities-related costs. These expenses include costs incurred in the development, implementation and maintenance of internal use software, including platform and related infrastructure. Technology and development costs are expensed as incurred, except to the extent that such costs are associated with internal use software development that qualifies for capitalization, which are then recorded as internal use software development costs, net on the Company's consolidated balance sheets. The Company amortizes internal use software development costs that relate to its revenue-producing activities on the Company's platform to cost of revenue and amortizes other internal use software development costs to technology and development costs or general and administrative expenses, depending on the nature of the related project. The Company amortizes acquired intangibles associated with technology and development functions from its business acquisitions over their estimated useful lives.

General and Administrative. The Company's general and administrative expenses consist primarily of personnel costs, including salaries, bonuses, and stock-based compensation, associated with the Company's executive, finance, legal, human resources, compliance, and other administrative personnel, as well as accounting and legal professional services fees, facilities-related costs and depreciation and amortization, and other corporate-related expenses. General and administrative expenses also include amortization of internal use software development costs and acquired intangible assets from the Company's business acquisitions over their estimated useful lives that relate to general and administrative functions.

Merger, Acquisition, and Restructuring Costs. The Company's merger, acquisition, and restructuring costs consist primarily of professional service fees associated with merger and acquisition activities, cash-based employee termination costs and stock-based compensation charges associated with mergers, acquisitions, or restructuring activities, and other restructuring activities, including facility closures and relocation costs.

Stock-Based Compensation

Compensation expense related to employee and non-employee stock-based awards is measured and recognized in the consolidated financial statements based on the fair value of the awards granted. The Company granted awards to employees that vest based solely on continued service, or service conditions, awards that vest based on the achievement of performance targets, or performance conditions, and awards that vest based on our stock price exceeding a peer index, or market conditions. The fair value of each option award containing service and/or performance conditions is estimated on the grant date using the Black-Scholes option-pricing model. The fair value of awards containing market conditions is estimated using a Monte-Carlo lattice model. For service condition awards, stock-based compensation expense is recognized on a straight-line basis over the requisite service periods of the awards, which is generally four years. For performance condition and market condition awards, stock-based compensation expense is recognized using a graded vesting model over the requisite service period of the awards. For market condition awards, expense recognized is not subsequently reversed if the market conditions are not achieved.

The assumptions and estimates used in the Black-Scholes pricing model are as follows:

Fair Value of Common Stock. The fair value of common stock is based on the closing price of the Company's common stock as reported on the NASDAQ on the grant date.

Table of Contents

Risk-Free Interest Rate. The Company bases the risk-free interest rate used in the Black-Scholes option-pricing model on the yields of U.S. Treasury securities with maturities appropriate for the term of stock option awards.

Expected Term. For employee stock options in which the Company did not have significant history and that contain service conditions, the Company applies the simplified approach, in which the expected term of an award is presumed to be the mid-point between the vesting date and the expiration date of the award. For employee stock options issued in the periods in which the Company did have significant history and that contain service conditions, the expected term is determined based on historical trends. The expected term of employee stock options that contain performance conditions represents the weighted-average period that the stock options are estimated to remain outstanding.

Volatility. For grants issued in periods in which the Company did not have significant trading history for the Company’s common stock, the Company determined the price volatility based on the historical volatilities of a publicly traded peer group based on daily price observations over a period equivalent to the expected term of the stock option grants. For grants issued in periods in which the Company has sufficient history, the computation of the expected volatility assumption is based on the historical volatility of the Company’s common stock.

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

Determining the fair value of stock-based awards using a pricing model requires judgment. The Company’s use of the Black-Scholes option-pricing model requires the input of subjective assumptions such as the expected term of the award, the expected volatility of the price of the Company’s common stock, risk-free interest rates, and the expected dividend yield of the Company’s common stock. The assumptions used in the Company’s valuation model represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, the Company’s stock-based compensation expense could be materially different in the future.

Income Taxes

Deferred income tax assets and liabilities are determined based upon the net tax effects of the differences between the Company’s consolidated financial statement carrying amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed.

A valuation allowance is used to reduce some or all of the deferred tax assets if, based upon the weight of available evidence, it is more likely than not that those deferred tax assets will not be realized. The Company has established a full valuation allowance to offset its domestic net deferred tax assets due to the uncertainty of realizing future tax benefits from the net operating loss carryforwards and other deferred tax assets.

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

Capital Stock

The Company has authorized capital stock of 500,000,000 shares of common stock and 10,000,000 shares of preferred stock. The Company has issued common stock, which is included in outstanding common stock on the Company's consolidated balance sheets. During 2021, the Company also repurchased shares of common stock, which was recorded as treasury stock on the Company's consolidated balance sheets. The Company has not issued any shares of its preferred stock subsequent to the Company's initial public offering ("IPO") and does not have any preferred stock outstanding.

The Company is required to reserve and keep available out of its authorized but unissued shares of common stock such number of shares sufficient to affect the conversion of all shares granted and available for grant under the Company’s stock award plans. The number of shares of the Company's stock reserved for these purposes at December 31, 2021 was 28,574,088.

Table of Contents

The board of directors is authorized to establish, from time to time, the number of shares to be included in each series of preferred stock, and to fix the designation, powers, privileges, preferences, and relative participating, optional or other rights, if any, of the shares of each series of preferred stock, and any of its qualifications, limitations or restrictions.

Net Income (Loss) Per Share Attributable to Common Stockholders

Basic net income (loss) per share of common stock is calculated by dividing the net income (loss) by the weighted-average number of shares of common stock outstanding. Diluted income (loss) per share attributable to common stockholders adjusts the basic weighted-average number of shares of common stock outstanding for the effect of potentially dilutive securities during the period. Potentially dilutive securities consist of stock options, restricted stock awards, restricted stock units, potential shares issuable under the Company's Employee Stock Purchase Plan ("ESPP"), shares held in escrow, potential shares issuable as part of contingent consideration as a result of business combinations, and potential shares issuable as part of the Convertible Senior Notes. For purposes of this calculation, potentially dilutive securities are excluded from the calculation of diluted net income (loss) per share if their effect is anti-dilutive.

Comprehensive Income (Loss)

Comprehensive income (loss) encompasses all changes in equity other than those arising from transactions with stockholders, and consists of net income (loss), unrealized gains (losses) on investments and foreign currency translation adjustments.

Cash and Cash Equivalents

The Company invests excess cash primarily in money market funds, corporate debt securities, and highly liquid debt instruments of the U.S. government and its agencies.The Company classifies investments held in money market funds as cash equivalents because the money market funds have weighted-average maturities at the date of purchase of less than 90 days. Investments held in U.S. government and agency bonds and corporate debt securities with stated maturities of less than one year are classified as short-term investments included in marketable securities and prepaid expenses and other current assets. Investments held in U.S. government and agency bonds and corporate debt securities with stated maturities of over a year are classified as long-term investments included in other assets, non-current on the Company’s consolidated balance sheets, as the Company does not expect to redeem or sell these securities within one year from the balance sheet date.

The Company determines the appropriate classification of investments in marketable securities at the time of purchase and reevaluates such designation at each balance sheet date. The Company classifies and accounts for the Company’s marketable securities as available-for-sale, and as a result carries the securities at fair value and reports the unrealized gains and losses in the consolidated statements of comprehensive income (loss) and as a component of stockholders’ equity. The Company determines any realized gains or losses on the sale of marketable securities on a specific identification method, and the Company records such gains and losses as a component of other income, net on the Company’s consolidated statements of operations.

Restricted Cash

The Company classifies certain restricted cash balances within prepaid expenses and other current assets and other assets, non-current on the consolidated balance sheets based upon the term of the remaining restrictions. At December 31, 2021 and 2020, the Company had restricted cash of $0.3 million and $0.1 million, respectively.

Accounts Receivable Allowance for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount, are unsecured, and do not bear interest. The allowance for doubtful accounts is based on the best estimate of the amount of probable credit losses in existing accounts receivable. The allowance for doubtful accounts is determined based on historical collection experience and the review in each period of the status of the then-outstanding accounts receivable, while taking into consideration current client information, subsequent collection history and other relevant data. The Company reviews the allowance for doubtful accounts on a quarterly basis. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.

Property and Equipment, Net

Property and equipment, which includes amounts recorded under finance leases, are recorded at historical cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method based upon the estimated useful lives of the assets. The estimated useful lives of the Company’s property and equipment are as follows:

Years

Computer equipment and network hardware 3

Furniture, fixtures and office equipment 5 to 7

Leasehold improvements Shorter of useful life or life of lease

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

Internal Use Software Development Costs

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

Software development activities generally consist of three stages, (i) the planning stage, (ii) the application and infrastructure development stage, and (iii) the post implementation stage. Costs incurred in the planning and post implementation stages of software development, including costs associated with the post-configuration training and repairs and maintenance of the developed technologies, are expensed as incurred. The Company capitalizes costs associated with software developed for internal use when the planning stage is completed, management has authorized further funding for the completion of the project, and it is probable that the project will be completed and perform as intended. Costs incurred in the application and infrastructure development stages, including significant enhancements and upgrades, are capitalized. Capitalization ends once a project is substantially complete and the software and technologies are ready for their intended purpose. Internal use software development costs are amortized using a straight-line method over the estimated useful life of three years, commencing when the software is ready for its intended use. The straight-line recognition method approximates the manner in which the expected benefit will be derived.

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

Capitalized Costs Incurred in Cloud Computing Arrangements

Cloud computing arrangements, such as software as a service and other hosting arrangements, are evaluated for capitalized implementation costs in a similar manner as capitalized software development costs. If a cloud computing arrangement includes a software license, the software license element of the arrangement is accounted for in a manner consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the service element of the arrangement is accounted for as a service contract. The Company capitalized certain implementation costs for its cloud computing arrangements that are service contracts, which are included within prepaid expenses and other current assets and other assets, non-current within the consolidated balance sheets. The Company amortizes capitalized implementation costs in a cloud computing arrangement over the life of the service contract, which generally is three years.

Intangible Assets

Intangible assets primarily consist of acquired developed technology, client relationships, and non-compete agreements resulting from business combinations, which are recorded at acquisition-date fair value, less accumulated amortization. The Company determines the appropriate useful life of its intangible assets by performing an analysis of expected cash flows of the acquired assets. Intangible assets are amortized over their estimated useful lives using a straight-line method, which approximates the pattern in which the economic benefits are consumed.

The Company’s intangible assets are being amortized over their estimated useful lives as follows:

80

Table of Contents

Years

Developed technology 5

In-process research and development 3 to 5

Customer relationships 2 to 4

Non-compete agreements 1 to 2

Other intangible assets 0.25 to 1.5

Intangible assets are reviewed for impairment indicators at least annually and whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used, or any other significant adverse change that would indicate that the carrying amount of an asset or group of assets may not be recoverable. For intangible assets used in operations, impairment losses are only recorded if the asset’s carrying amount is not recoverable through its undiscounted, probability-weighted future cash flows. The Company measures the impairment loss based on the difference between the carrying amount and estimated fair value.

Impairment of Long-Lived Assets including Internal Use Capitalized Software Costs

The Company assesses the recoverability of its long-lived assets when events or changes in circumstances indicate their carrying value may not be recoverable. Such events or changes in circumstances may include: a significant adverse change in the extent or manner in which a long-lived asset is being used, significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of a long-lived asset, current or future operating or cash flow losses that demonstrate continuing losses associated with the use of a long-lived asset, or a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The Company performs impairment testing at the asset group level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The Company assesses recoverability of a long-lived asset by determining whether the carrying value of the asset group can be recovered through projected undiscounted cash flows over their remaining lives. If the carrying value of the asset group exceeds the forecasted undiscounted cash flows, an impairment loss is recognized, measured as the amount by which the carrying amount exceeds estimated fair value. An impairment loss is charged to operations in the period in which management determines such impairment.

Business Combinations

The results of businesses acquired in a business combination are included in the Company’s consolidated financial statements from the date of acquisition. The Company allocates the purchase price of a business combination, which is the sum of the consideration provided, which may consist of cash, equity or a combination of the two, to the identifiable assets and liabilities of the acquired business at their acquisition date fair values. The excess of the purchase price over the amount allocated to the identifiable assets and liabilities, if any, is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, estimates of future revenues and cash flows, discount rates and selection of comparable companies.

When the Company issues stock-based or cash awards to an acquired company’s stockholders, the Company evaluates whether the awards are contingent consideration or compensation for post-business combination services. The evaluation includes, among other things, whether the vesting of the awards is contingent on the continued employment of the selling stockholder beyond the acquisition date. If continued employment is required for vesting, the awards are treated as compensation for post-acquisition services and recognized as expense over the requisite service period.

The Company estimates the fair value of intangible assets acquired generally using a discounted cash flow approach, which includes an analysis of the future cash flows expected to be generated by the asset and the risk associated with achieving these cash flows. The key assumptions used in the discounted cash flow model include the discount rate that is applied to the forecasted future cash flows to calculate the present value of those cash flows and the estimate of future cash flows attributable to the acquired intangible asset, which include revenue, expenses and taxes. The carrying value of acquired working capital assets and liabilities approximates its fair value, given the short-term nature of these assets and liabilities.

Acquisition-related transaction costs are not included as a component of consideration transferred, but are accounted for as an expense in the period in which the costs are incurred.

Goodwill

Goodwill represents the excess of the aggregate fair value of the consideration transferred in a business combination over the fair value of the assets acquired, net of liabilities assumed. Goodwill is not amortized, but is subject to impairment testing conducted annually during the fourth quarter or more frequently if events or changes in circumstances indicate that goodwill may be impaired.

In accordance with guidance related to impairment testing, the Company has the option to first assess qualitative factors to determine whether or not it is necessary to perform the quantitative goodwill impairment test. If the qualitative assessment option is not elected, or if the qualitative assessment indicates that it is more likely than not that the fair value is less than its carrying amount, a quantitative analysis is then performed. The quantitative analysis, if performed, compares the estimated fair value of the Company with its respective carrying amount, including goodwill. If the estimated fair value of the Company exceeds its carrying amount, including goodwill, goodwill is considered not to be impaired and no additional steps are necessary. If the fair value is less than the carrying amount, including goodwill, then an impairment adjustment must be recorded up to the carrying amount of goodwill.

The Company operates as a single operating segment and has identified a single reporting unit.

Operating and Finance Leases

The Company determines if an arrangement is a lease at inception. A contract is or contains a lease if it conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company's classes of assets that are leased include office facilities, data centers, and equipment. The Company has elected not to recognize short-term leases on the balance sheet, nor separate lease and non-lease components for data center leases. In addition, the Company utilized the portfolio approach to group leases with similar characteristics together.

For identified leases, the Company used its incremental borrowing rate to discount the related future payment obligations, which represents the rate of interest the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment.

The Company records rent expense for operating leases, including leases of office locations, data centers, and equipment, on a straight-line basis over the lease term. The straight-line calculation of rent expense includes rent escalations on certain leases, as well as lease incentives provided by the landlords, including payments for leasehold improvements and rent-free periods. The Company begins recognition of rent expense on the commencement date, which is generally the date that the asset is made available for use. Lease liability, which represents the present value of the Company's obligation related to the estimated future lease payments, is included in lease liabilities, current and lease liabilities, non-current within the consolidated balance sheets. These liability balances are reduced as lease related payments are made. For operating leases, the right of use ("ROU") asset is amortized on a periodic basis over the expected term of the lease (see Note 16). Finance leases are included in property and equipment, net on the consolidated balance sheets.

Fair Value of Financial Instruments

The carrying amounts of the Company's cash equivalents, accounts receivable, accounts payable, accrued expenses, and seller payables approximate fair value due to the short-term nature of these instruments. Certain assets of the Company are recorded at their fair value, using the fair value hierarchy, on a recurring basis, and other assets and liabilities, including goodwill and intangible assets are subject to measurement at fair value on a non-recurring basis if they are deemed to be impaired as a result of an impairment review (see Note 5).

Concentration of Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents, restricted cash and accounts receivable. Cash and cash equivalents maintained with financial institutions exceed applicable federally insured limits.

Accounts receivable include amounts due from buyers with principal operations primarily in the United States. The Company performs ongoing credit evaluations of its buyers.

At December 31, 2021, two buyers accounted for 44% and 10% respectively, of consolidated accounts receivable. At December 31, 2020, two buyers accounted for 33% and 12%, respectively, of accounts receivable.

The Company recognizes revenue from its contracts with sellers. No seller of advertising inventory accounted for 10% or more of revenue during the years ended December 31, 2021, 2020, and 2019.

82

Table of Contents

At December 31, 2021, one seller of advertising inventory accounted for 21% of accounts payable and at December 31, 2020, one seller of advertising inventory accounted for 18% of accounts payable.

Foreign Currency Transactions and Translation

Transactions in foreign currencies are translated into the functional currency of the applicable entity at the rates of exchange in effect at the date of the transaction. Foreign exchange gains or losses were included in foreign exchange (gain) loss, net in the accompanying consolidated statements of operations. To the extent that the functional currency is different from the U.S. Dollar, the financial statements have then been translated into U.S. Dollars using period-end exchange rates for assets and liabilities and average exchange rates for the results of operations. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive income (loss) on the consolidated balance sheets.

Recently Adopted Accounting Standards

In December 2019, the FASB issued ASU 2019-12—Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to general principles in Topic 740 and clarifies and amends existing guidance for clarity and consistent application. This guidance is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2020 including interim reporting periods within those fiscal years. The Company adopted ASU 2019-12 as of January 1, 2021. The standard did not have a material impact on its consolidated financial statements and related disclosures.

In January 2020, the FASB issued ASU 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) ("ASU 2020-01"), which clarifies the interaction of the accounting for equity securities under Topic 321, the accounting for equity method investments in Topic 323, and the accounting for certain forward contracts and purchased options in Topic 815. This guidance is effective for fiscal years beginning after December 15, 2020, including interim reporting periods within those fiscal years. The Company adopted ASU 2020-01 as of January 1, 2021. The standard did not have a material impact on its consolidated financial statements and related disclosures.

On January 1, 2021, the Company adopted ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity(Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (ASU "2020-06") on a prospective basis, which simplifies the accounting for convertible instruments by reducing the number of accounting models available for convertible debt instruments that require separating embedded conversion features from convertible instruments. This guidance also eliminates the treasury stock method to calculate diluted earnings per share for convertible instruments and requires the use of the if-converted method. The adoption of this standard is included in the financial statements as of and for the year ended December 31, 2021. Refer to Note 18—"Debt" for additional information related to accounting for convertible debt issued during the year.

Recent Accounting Pronouncements Not Yet Adopted

In July 2021, the FASB issued Update No. 2021-05, Leases (Topic 842)—Lessors – Certain Leases with Variable Lease Payments ("ASU 2021-05"). ASU 2021-05 requires a lessor to classify a lease with variable lease payments that do not depend on an index or rate as an operating lease if specified criteria are met. This guidance will be effective on January 1, 2022, either retrospectively to leases that commenced or were modified on or after our adoption of ASU 2016-02 on January 1, 2019, or on a prospective basis, with early adoption permitted. The Company will adopt this standard prospectively and does not expect the adoption of this guidance to have a material impact on the Company's consolidated financial statements.
