MAGNITE, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)
Note 1—Organization and Summary of Significant Accounting Policies
Company Overview
Magnite, Inc. ("Magnite" or the "Company"), formerly known as The Rubicon Project, Inc., was formed in Delaware and began operations in April 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.
The Company provides a technology solution to automate the purchase and sale of digital advertising inventory. 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.
Basis of Presentation and Summary of Significant Accounting Policies
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles, or GAAP, for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement of the results for the interim period presented have been included. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for any future interim period, the year ending December 31, 2021, or for any future year.
The condensed consolidated balance sheet at December 31, 2020 has been derived from the audited financial statements at that date, but does not include all of the disclosures required by GAAP. The accompanying condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto for the year ended December 31, 2020 included in its 2020 Annual Report on Form 10-K.
Aside from the adoption of ASU 2020-06, as described below, there have been no significant changes in the Company's accounting policies from those disclosed in its audited consolidated financial statements and notes thereto for the year ended December 31, 2020 included in its Annual Report on Form 10-K.
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported 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 nine months ended September 30, 2021, this uncertainty continued to result in a higher level of judgment related to its estimates and assumptions. As of the date of issuance of the condensed consolidated financial statements for the three and nine months ended September 30, 2021, 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.
Recently Adopted Accounting Standards
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
10

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 September 30, 2021 and for the three and nine months ended September 30, 2021 and September 30, 2020, respectively. Refer to Note 14—"Convertible Senior Notes" for additional information related to accounting for convertible debt issued during the nine months ended September 30, 2021.
On January 1, 2021, the Company adopted 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. There was no material impact to the quarterly or year to date income tax provision.
Recent Accounting Pronouncements
In March 2020, the FASB issued Update No. 2020-04, Reference Rate Reform (Topic 848), which provides temporary optional guidance to companies impacted by the transition away from the LIBOR. The amendment provides certain expedients and exceptions to applying GAAP in order to lessen the potential accounting burden when contracts, hedging relationships, and other transactions that reference LIBOR as a benchmark rate are modified. Further, in January 2021, the FASB issued Update No. 2021-01, Reference Rate Reform (Topic 848), which clarifies the scope of Topic 848 so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions in Topic 848. These amendments are effective upon issuance and expire on December 31, 2022. The Company is currently assessing the impact of the LIBOR transition on the Company's condensed consolidated financial statements.
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 is currently assessing the impact of the new guidance on the Company's condensed consolidated financial statements.
The Company does not believe there are any other recently issued and effective or not yet effective pronouncements that would have or are expected to have any significant effect on the Company’s financial position, cash flows or results of operations.

For the three and nine months ended September 30, 2021, diluted shares used to compute diluted earnings per share included outstanding performance stock units granted during April 2020, April 2021, and August 2021 based on a current achievement level of 150%, 0%, and 0%, respectively. Refer to Note 9—"Stock-Based Compensation" for additional information related to performance stock units.
For the three and nine months ended September 30, 2021, diluted shares used to compute diluted earnings per share excluded the shares that would be issuable assuming conversion of all of the Convertible Senior Notes (as defined in Note 14) because they are anti-dilutive. Diluted earnings per share for the Convertible Senior Notes is calculated under the if-converted method in accordance with ASC 260, Earnings Per Share. The Convertible Senior Notes have an initial conversion rate of 15.6539 shares of common stock per $1,000 principal amount of the Convertible Senior Notes, which will be subject to anti-dilution adjustments in certain circumstances. As of September 30, 2021, the number of shares that would be issuable assuming conversion of all of the Convertible Senior Notes is approximately 6,261,560. Refer to Note 14—"Convertible Senior Notes" for additional information related to accounting for Convertible Senior Notes issued and associated Capped Call Transactions.
Note 3—Revenue
For the majority of transactions on the Company's platform, the Company reports revenue on a net basis as it does not act as the principal in the purchase and sale of digital advertising inventory because it does not have control of the digital advertising inventory and does not set prices agreed upon within the auction marketplace. For certain advertising campaigns that are transacted through insertion orders, the Company reports revenue on a gross basis, based primarily on its determination that the Company acts as the primary obligor in the delivery of advertising campaigns for buyers with respect to such transactions.
For periods prior to the SpotX Acquisition, revenue reported on a gross basis was generally less than 3% of the Company's total revenue. As a result of the SpotX Acquisition, an increased percentage of the Company's revenue is reported on a gross basis. The following table presents our revenue recognized on a net basis and on a gross basis for the three and nine months ended September 30, 2021 and September 30, 2020, respectively.

Payment terms are specified in agreements between the Company and the buyers and sellers on its platform. The Company generally bills buyers at the end of each month for the full purchase price of impressions filled in that month. The Company recognizes volume discounts as a reduction of revenue as they are incurred. Specific payment terms may vary by agreement, but are generally seventy-five days or less. The Company's accounts receivable are recorded at the amount of gross billings to buyers, net of allowances for the amounts the Company is responsible to collect. The Company's accounts payable related to amounts due to sellers are recorded at the net amount payable to sellers (see Note 5). Accordingly, both accounts receivable and accounts payable appear large in relation to revenue reported on a net basis.
Accounts receivable are recorded at the invoiced amount, are unsecured, and do not bear interest. The allowance for doubtful accounts is reviewed quarterly, requires judgment, and is based on the best estimate of the amount of probable credit losses in existing accounts receivable. The Company reviews the status of the then-outstanding accounts receivable on a customer-by-customer basis, taking into consideration the aging schedule of receivables, its historical collection experience, current information regarding the client, subsequent collection history, and other relevant data, in establishing the allowance for doubtful accounts. Accounts receivable is presented net of an allowance for doubtful accounts of $4.0 million at September 30, 2021, and $2.4 million at December 31, 2020. Accounts receivable are written off against the allowance for doubtful accounts when the Company determines amounts are no longer collectible.
The Company reviews the associated payable to sellers for recovery of buyer receivable allowance and write-offs; in some cases, the Company can reduce the payable to sellers. The reduction of seller payables related to recovery of uncollected buyer receivables is netted against allowance expense. The contra seller payables related to recoveries were $2.2 million and $1.5 million as of September 30, 2021 and December 31, 2020, respectively.
The following is a summary of activity in the allowance for doubtful accounts for the three and nine months ended September 30, 2021 and 2020:

During the three and nine months ended September 30, 2021, the provision for expected credit losses associated with accounts receivable increased by $0.3 million and $0.9 million was offset by decreases of contra seller payables related to recoveries of uncollected buyer receivables of an immaterial amount and $0.6 million, which resulted in $0.4 million and $0.2 million, respectively, of bad debt recoveries. During the three and nine months ended September 30, 2020, the provision for expected credit losses associated with accounts receivable of $(0.3) million and $1.9 million was offset by increases of contra seller payables related to recoveries of uncollected buyer receivables of $(0.3) million and $1.8 million, respectively, which resulted in an immaterial amount of bad debt expense during the period.
Note 4—Fair Value Measurements
Recurring Fair Value Measurements    
Fair value represents the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Observable inputs are based on market data obtained from independent sources. The fair value hierarchy is based on the following three levels of inputs, of which the first two are considered observable and the last one is considered unobservable:
Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3 – Unobservable inputs.

At September 30, 2021 and December 31, 2020, cash equivalents of $7.9 million and $7.9 million, respectively, consisted of money market funds and commercial paper, with original maturities of three months or less. The carrying amounts of cash equivalents are classified as Level 1 or Level 2 depending on whether or not their fair values are based on quoted market prices for identical securities that are traded in an active market.
At September 30, 2021, the Company had Convertible Senior Notes (as defined in Note 14) included in its balance sheet. The estimated fair value of the Company's Convertible Senior Notes was $341.0 million as of September 30, 2021. The estimated fair value of Convertible Senior Notes is based on market rates and the closing trading price of the Convertible Senior Notes as of September 30, 2021 and is classified as Level 2 in the fair value hierarchy.
There were no transfers between Level 1 and Level 2 fair value measurements during the nine months ended September 30, 2021 and the year ended December 31, 2020.

2021 Acquisition—SpotX
On April 30, 2021, the Company completed the SpotX Acquisition, pursuant to a Stock Purchase Agreement, dated as of February 4, 2021 (the "Purchase Agreement"), by and between the Company and RTL US Holdings, Inc. ("RTL"). The initial purchase price for the SpotX Acquisition was $560 million in cash ("Cash Consideration") and 14,000,000 shares of the Company's common stock. Per the terms of the Purchase Agreement, at the completion of the Company’s offering of its Convertible Senior Notes, RTL elected to increase the Cash Consideration by an amount equal to 20% of the gross proceeds of the Convertible Senior Notes (which amount was equal to $80 million) and to reduce the number of shares of common stock it would otherwise receive by a number of shares of common stock equal to 20% of the gross proceeds of the proposed offering of notes ($80 million) divided by the closing price of a share of our common stock on the trading day immediately prior to the date of pricing of the proposed offering of notes ($49.21). As a result of this election, the adjusted purchase price was $1.1 billion, prior to customary working capital adjustments and other adjustments, consisting of $640 million in cash plus 12,374,315 shares of common stock (based on the fair value of the Company's common stock on April 30, 2021). The Cash Consideration is subject to customary working capital and other adjustments. The working capital was approximately $65.2 million, including cash balances acquired and other working capital adjustments, resulting in a total purchase price of $1.2 billion. The Company financed the Cash Consideration through borrowings under the Term Loan B Facility (Note 15) and the Convertible Senior Notes (Note 14).
In accordance with ASC 805, the Company recorded the acquisition based on the fair value of the consideration transferred and then allocated the purchase price to the identifiable assets acquired and liabilities assumed based on their respective fair values as of the acquisition date. The excess of the value of consideration transferred over the aggregate fair value of those net assets was recorded as goodwill. Any identified definite lived intangible assets will be amortized over their estimated useful lives and any identified intangible assets with indefinite useful lives and goodwill will not be amortized but will be tested for impairment at least annually. All intangible assets and goodwill will be tested for impairment when certain indicators are present. 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.
Management's purchase price allocation is preliminary and subject to change pending finalization of the valuation, including finalization of tax attributes and tax related liabilities. Under the acquisition method of accounting for business combinations, if the Company identifies changes to acquired deferred tax asset ("DTA") valuation allowances or liabilities related to uncertain tax positions during the measurement period, and they are related to new information obtained about facts and circumstances that existed as of the acquisition date, those changes are considered a measurement-period adjustment, and the Company will record the offset to goodwill. The Company records all other changes to DTA valuation allowances and liabilities related to uncertain tax positions in current- period income tax expense.
For purposes of measuring the estimated fair value, where applicable, of the assets acquired and the liabilities assumed as reflected in the unaudited condensed combined financial information, the Company has applied the guidance in ASC 820, Fair Value Measurement, which establishes a framework for measuring fair value. In accordance with ASC 820, fair value is an exit price and is defined as "the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date." Under ASC 805, acquisition-related transaction costs and acquisition-related restructuring charges are not included as components of consideration transferred but are accounted for as expenses in the period in which the costs are incurred.
The following table summarizes the total purchase consideration (in thousands):
16

Cash Consideration $ 640,000 
Stock Consideration (Fair Value of Shares of Magnite common stock) 495,591 
Working capital adjustment 65,152 
Total purchase consideration $ 1,200,743 
The purchase consideration for the SpotX Acquisition included 12,374,315 shares of the Company's common stock with a fair value of approximately $495.6 million, based on the close price of the Company's common stock at closing on April 30, 2021, which was $40.05 per share, and working capital adjustment of $65.2 million, mainly consisting of cash balances acquired on the date of the SpotX Acquisition and other opening balance sheet adjustments.
The fair value of the purchase price was allocated to the identifiable assets acquired and liabilities assumed based upon their estimated fair values as of the date of the SpotX Acquisition as set forth below:
Cash $ 81,967 
Restricted cash 199 
Accounts receivable 199,649 
Prepaid and other assets, current 12,308 
Fixed assets 5,093 
Intangible assets 429,600 
Right-of-use lease asset 11,785 
Goodwill 790,466 
Total assets to be acquired 1,531,067 
Accounts payable and accrued expenses 205,913 
Other current liabilities 7,169 
Lease liabilities 12,625 
Deferred tax liability, net 104,617 
Total liabilities to be assumed 330,324 
Total purchase price $ 1,200,743 
The Company believes the amount of goodwill resulting from the purchase price allocation is primarily attributable to expected synergies from the assembled workforce, an increase in development capabilities, increased offerings to customers, and enhanced opportunities for growth and innovation. Goodwill will not be amortized but instead will be tested for impairment at least annually or more frequently if certain indicators of impairment are present. In the event that goodwill has become impaired, the Company will record an expense for the amount impaired during the quarter in which the determination is made. The acquired intangibles and goodwill resulting from the SpotX Acquisition are not amortizable for tax purposes.
The following table summarizes the components of the intangible assets and estimated useful lives as of the date of the SpotX Acquisition (dollars in thousands):
Estimated Useful Life
Technology $ 280,400  5 years
Customer relationships 130,300 
2 to 4 years
Backlog 11,100 
<1 year
In-process research and development 5,800 
3 years*
Non-compete agreements 1,500  1 year
Trademarks 500 
<1 year
Total intangible assets acquired $ 429,600 
* In-process research and development consists of six projects with a weighted-average useful life of 3.0 years. Amortization begins once associated projects are completed and it is determined the projects have alternative future use.
The fair value of the acquired technology and in-process research and development was valued using the Excess Earnings Method. This methodology included allocating future revenue projections to the existing technologies and applying decay rates and appropriate discount rates that reflect the respective intangible asset's relative risk profile when compared to other intangible assets as well as the discount rate for the overall business.
17

The Company used the Loss‐of‐Revenue and Income Method in its valuation of the existing customer relationships and non-compete agreements. To the extent that future cash flows of the business would be negatively affected in the absence of these relationships and non-compete agreements, they would be deemed to have economic value. This method attempts to quantify the scenario whereby the owner loses the right to the intangible asset and the resulting losses of revenue and income. Under this analysis, the value of the cash flows with the intangible asset is compared to the value of the cash flows without the intangible asset and the difference represents the value of the intangible asset. This methodology included applying a discount rate and the expected timing it would take to further enhance customer relationships.
The fair value of the backlog was based on the Excess Earnings Method, taking into consideration the existing contracts as of the date of the SpotX Acquisition and the respective cost to complete the servicing of the existing agreements. The resulting stream of after tax earnings were discounted to present value by applying an appropriate discount rate for the asset. The discount rate was selected based on the intangible asset’s relative risk profile when compared to the other intangible assets as well as the discount rate for the overall business.
The fair value of the trademarks was based on the Income Approach, specifically the Relief‐from‐Royalty Method. Under this method, data is obtained regarding actual royalty payments made for similar intangible assets. After the appropriate royalty rate is determined, the reasonable royalty savings is then discounted to its present value over the remaining technological, economic, or legal life of the intangible asset.
Intangible assets are generally amortized on a straight-line basis, which approximates the pattern in which the economic benefits are consumed, over their estimated useful lives. Amortization of developed technology is included in cost of revenues and the amortization of customer relationships, backlog, non-compete agreements, and trademarks is included in sales and marketing expenses in the condensed consolidated statement of operations. Once the projects associated with acquired in-process research and development are completed, amortization will be included in cost of revenues in the condensed consolidated statement of operations. The intangible assets generated in the SpotX Acquisition are not tax deductible.
In connection with the SpotX Acquisition, the Company recorded deferred tax liabilities related to definite-lived intangible assets that were acquired of $113.0 million. As a result of this deferred tax liability balance, the Company reduced its deferred tax asset valuation allowance by $56.2 million. Such reduction was recognized as an income tax benefit in the condensed consolidated statement of operations for the nine months ended September 30, 2021. The deferred tax liability was calculated based on an estimated combined tax rate of 26.3%.
The Company recognized approximately $0.8 million and $27.9 million of acquisition related costs included in the "Merger, acquisition, and restructuring costs" in the Company's condensed consolidated statement of operations during the three and nine months ended September 30, 2021 related to the SpotX Acquisition.

2021 Acquisition—SpringServe
On July 1, 2021, the Company completed the acquisition of ServeMotion, Inc., a Delaware corporation (including its wholly owned subsidiary, SpringServe, LLC, "SpringServe"), through the Company's wholly-owned subsidiary, SpotX, pursuant to a definitive agreement entered into on July 1, 2021. As a result of the SpringServe Acquisition, SpringServe has become a wholly-owned subsidiary of SpotX, and a wholly-owned indirect subsidiary of the Company.
The following table summarizes the total estimated purchase consideration (in thousands):
Cash Consideration $ 31,136 
SpotX initial cash investment in SpringServe 2,075 
Fair value appreciation of SpotX purchase right 7,450 
Indemnification claims - holdback 1,409 
Total purchase consideration $ 42,070 
In 2020, SpotX made a minority investment of $2.1 million in SpringServe in conjunction with a strategic partnership agreement between the two companies, which included an option agreement to purchase SpringServe. At the time of Magnite's acquisition of SpotX, the fair value of SpotX's minority investment and purchase right were valued at a combined $7.5 million for a total minority investment and purchase right of $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 acquisition.
In accordance with ASC 805, the Company recorded the acquisition based on the fair value of the consideration transferred and then allocated the purchase price to the identifiable assets acquired and liabilities assumed based on their respective fair values as of the acquisition date. The excess of the value of consideration transferred over the aggregate fair value of those net assets was recorded as goodwill. Any identified definite lived intangible assets will be amortized over their estimated useful lives and any identified intangible assets with indefinite useful lives and goodwill will not be amortized but will be tested for impairment at least annually. All intangible assets and goodwill will be tested for impairment when certain indicators are present. 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.
Management's purchase price allocation is preliminary and subject to change pending finalization of the valuation, including finalization of tax attributes and tax related liabilities. Under the acquisition method of accounting for business combinations, if the Company identifies changes to acquired DTA valuation allowances or liabilities related to uncertain tax positions during the measurement period, and they are related to new information obtained about facts and circumstances that existed as of the acquisition date, those changes are considered a measurement-period adjustment, and the Company will record the offset to goodwill. The Company records all other changes to DTA valuation allowances and liabilities related to uncertain tax positions in current- period income tax expense.
For purposes of measuring the estimated fair value, where applicable, of the assets acquired and the liabilities assumed as reflected in the unaudited condensed combined financial information, the Company has applied the guidance in ASC 820, Fair Value Measurement, which establishes a framework for measuring fair value. In accordance with ASC 820, fair value is an exit price and is defined as "the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date." Under ASC 805, acquisition-related transaction costs and acquisition-related restructuring charges are not included as components of consideration transferred but are accounted for as expenses in the period in which the costs are incurred.
The fair value of the purchase price was allocated to the identifiable assets acquired and liabilities assumed based upon their estimated fair values as of the date of the SpringServe Acquisition as set forth below:

Total preliminary purchase price $ 42,070 
The Company believes the amount of goodwill resulting from the purchase price allocation is primarily attributable to expected synergies from the assembled workforce, an increase in development capabilities, increased offerings to customers, and enhanced opportunities for growth and innovation. Goodwill will not be amortized but instead will be tested for impairment at least annually or more frequently if certain indicators of impairment are present. In the event that goodwill has become impaired, the Company will record an expense for the amount impaired during the quarter in which the determination is made.
The following table summarizes the components of the intangible assets and estimated useful lives as of the date of the SpringServe Acquisition (dollars in thousands):
Estimated Useful Life
Technology $ 15,500  5 years
Customer relationships 5,700  2 years
Trademarks and Trade Names 900  3 years
In-process research and development 800 
3 years*
Non-compete agreements 500  2 years
Total intangible assets acquired $ 23,400 
* In-process research and development consists of two projects with a weighted-average useful life of 3 years. Amortization begins once associated projects are completed and it is determined the projects have alternative future use.
Intangible assets are generally amortized on a straight-line basis, which approximates the pattern in which the economic benefits are consumed, over their estimated useful lives. Amortization of developed technology is included in cost of revenues and the amortization of customer relationships, non-compete agreements, and trademarks is included in sales and marketing expenses in the condensed consolidated statement of operations. Once the projects associated with acquired in-process research and development are completed, amortization will be included in cost of revenues in the condensed consolidated statement of operations. The acquired intangibles and goodwill resulting from the SpringServe Acquisition are not tax deductible.
In connection with the SpringServe Acquisition, the Company recorded deferred tax liabilities related to definite-lived intangible assets that were acquired of $6.2 million. As a result of this and the SpotX deferred tax liability balance, the Company recognized an income tax benefit in the condensed consolidated statement of operations for the nine months ended September 30, 2021. The deferred tax liability was calculated based on an estimated combined tax rate of 26.3%.
SpringServe Acquisition related costs included in the "Merger, acquisition, and restructuring costs" in the Company's condensed consolidated statement of operations during the three and nine months ended September 30, 2021 were immaterial.
Unaudited Pro Forma Information
The following table provides unaudited pro forma information as if the SpotX and SpringServe Acquisitions had been acquired by the Company as of January 1, 2020. The unaudited pro forma information reflects adjustments for additional amortization resulting from the fair value adjustments to assets acquired and liabilities assumed, adjustments for alignment of accounting policies, and transaction expenses as if the SpotX and SpringServe Acquisitions occurred on January 1, 2020. The pro forma results do not include any anticipated cost synergies or other effects of the combined companies. Accordingly, pro forma
20

amounts are not necessarily indicative of the results that actually would have occurred had the SpotX and SpringServe Acquisitions been completed on the dates indicated, nor is it indicative of the future operating results of the combined company.

During the three and nine months ended September 30, 2021, due to the process of integrating the operations of SpotX into the operations of the Company, the determination of SpotX's post-acquisition revenue and operating results on a standalone basis was impracticable. The SpringServe post-acquisition revenue and operating results on a standalone basis were immaterial.


Note 8—Merger, Acquisition, and Restructuring Costs
Merger, acquisition, and restructuring costs consist primarily of professional services fees and employee termination costs, including stock-based compensation charges, associated with the Telaria Merger, the SpotX Acquisition, and restructuring activities.
The following table summarizes merger, acquisition, and restructuring cost activity (in thousands):

Note 9—Stock-Based Compensation
The Company’s equity incentive plans provide for the grant of equity awards, including non-statutory or incentive stock options, restricted stock awards ("RSAs"), and restricted stock units ("RSUs"), to the Company's employees, officers, directors, and consultants. The Company's board of directors administers the plans. Options outstanding vest based upon continued service at
21

varying rates, but generally over four years from issuance with 25% vesting after one year of service and the remainder vesting monthly thereafter. RSAs and RSUs vest at varying rates, typically approximately 25% vesting after approximately one year of service and the remainder vesting annually, semi-annually, or quarterly thereafter. The restricted stock units granted in 2021 included 0.3 million that vest 50% on each of the first and second anniversaries of the grant date. Options, RSAs, and RSUs granted under the plans accelerate under certain circumstances for certain participants upon a change in control, as defined in the governing plan or award agreement, and termination of employment. An aggregate of 12,968,404 shares remained available for future grants at September 30, 2021 under the plans.

The weighted-average grant date fair value per share of restricted stock units granted during the nine months ended September 30, 2021 was $38.54. The aggregate fair value of restricted stock units that vested during the nine months ended September 30, 2021 was $126.1 million. At September 30, 2021, the intrinsic value of nonvested restricted stock units was $208.6 million. At September 30, 2021, the Company had unrecognized stock-based compensation expense relating to unvested restricted stock units of approximately $112.0 million, which is expected to be recognized over a weighted-average period of 2.5 years.
Performance Stock Units
In April 2020 and April 2021, the Company granted the Company's CEO 146,341 and 26,291 restricted stock units that vest based on certain stock price performance metrics with a fair value of $0.9 million and $1.4 million, respectively. The grant date fair value per share of restricted stock was $6.15 and $52.49, respectively, which was estimated using a Monte-Carlo lattice model. At September 30, 2021, the Company had unrecognized employee stock-based compensation expense for the April 2020 and April 2021 grants of approximately $0.5 million and $1.2 million, which is expected to be recognized over the remaining 1.5 years and 2.5 years, respectively. Between 0% and 150% of the performance stock units will vest on the third anniversary of its grant date.
In August 2021, the Company granted the Company's CEO 379,635 restricted stock units, which are subject to both time-based and performance-based vesting conditions. The performance stock units consist of three equal tranches (each, a "Performance Tranche"), based on achievement of a share price condition if the Company achieves share price targets of $60.00, $80.00, and $100.00 over 60 consecutive trading days during a performance period commencing on August 26, 2022 and ending on August 26, 2026. To the extent any of the performance-based requirements are met, the Company's CEO must also provide continued service to the Company through at least August 26, 2024 to receive any shares of common stock underlying the grant and through August 26, 2026 to receive all of the shares of common stock underlying the performance units that have satisfied the applicable performance-based requirement.
The fair value of each of the Performance Tranches was $3.0 million, $2.8 million, and $2.6 million, respectively, and have a grant date fair value per share of restricted stock of $23.94, $21.93, and $20.30, respectively, which was estimated using a Monte-Carlo lattice model. At September 30, 2021, the Company had unrecognized employee stock-based compensation expense of approximately $2.9 million, $2.7 million, and $2.5 million, which is expected to be recognized over the remaining 2.9 years, 3.9 years, and 4.9 years, respectively. Between 0% and 100% of the performance stock units will vest on each of the tranche dates.
During the three and nine months ended September 30, 2021, the Company recognized $0.4 million and $0.7 million, respectively, of stock-based compensation related to these performance stock units based on a performance measurement of 100%. The compensation expense will not be reversed if the performance metrics are not met.
Employee Stock Purchase Plan
In November 2013, the Company adopted the Company's 2014 Employee Stock Purchase Plan ("ESPP"). The ESPP is designed to enable eligible employees to periodically purchase shares of the Company's common stock at a discount through payroll deductions of up to 10% of their eligible compensation, subject to any plan limitations. At the end of each six-month offering period, employees are able to purchase shares at a price per share equal to 85% of the lower of the fair market value of the Company's common stock on the first trading day of the offering period or on the last trading day of the offering period. Offering periods generally commence and end in May and November of each year.
As of September 30, 2021, the Company has reserved 3,068,352 shares of its common stock for issuance under the ESPP. The ESPP has an evergreen provision pursuant to which the share reserve will automatically increase on January 1st of each year in an amount equal to 1% of the total number of shares of capital stock outstanding on December 31st of the preceding calendar year, although the Company’s board of directors may provide for a lesser increase, or no increase, in any year.
Stock-Based Compensation Expense
Total stock-based compensation expense recorded in the condensed consolidated statements of operations was as follows:

Note 10—Income Taxes
In determining quarterly provisions for income taxes, the Company uses the annual estimated effective tax rate applied to the actual year-to-date income. The Company's annual estimated effective tax rate differs from the statutory rate primarily as a result of state taxes, foreign taxes, deductible stock option expenses, nondeductible executive compensation, and changes in the Company's valuation allowance.
The Company adopted ASU 2019-12, during the three months ended March 31, 2021. There was no material impact to the quarterly income tax provision.
The Company recorded an income tax benefit of $4.7 million and expense of $0.4 million for the three months ended September 30, 2021 and 2020, respectively and an income tax benefit of $92.2 million and expense of $0.5 million for the nine months ended September 30, 2021 and 2020, respectively. The tax benefit for the three and nine months ended September 30, 2021 is primarily the result of the partial release of the domestic valuation allowance of $56.2 million related to the SpotX Acquisition, as well as the income tax benefit of a portion of the current year projected loss. The net deferred tax liabilities recorded in connection with the SpotX and SpringServe Acquisitions provided additional sources of taxable income to support the realizability of pre-existing deferred tax assets, and, as a result, the Company released a portion of its domestic valuation allowance and recognized a current benefit for a portion of the Company's projected losses. The Company continues to maintain a partial valuation allowance for the domestic deferred tax assets.
On March 11, 2021, the U.S. President signed into law the American Rescue Plan Act of 2021 ("ARP Act")—a $1.9 trillion coronavirus disease 2019 ("COVID-19") relief package. The ARP Act had limited income tax provisions. The Company has determined that the ARP Act will not have a material impact on the Company for the year ended December 31, 2021. On March 27, 2020, the U.S. President signed into law the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"), in response to the COVID-19 pandemic. The CARES Act is meant to infuse negatively affected companies with various tax cash benefits to ease the impact of the COVID-19 pandemic. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer-side social security payments, and net operating loss carryback periods. The Company has determined the tax implications of the CARES Act will not be material. In addition, various foreign jurisdictions where the Company has activity have enacted or are considering enacting a variety of measures that could impact our tax liabilities. The Company is monitoring new legislation and evaluating the potential tax implications of these measures globally.
Due to uncertainty as to the realization of benefits from the Company's domestic and certain international deferred tax assets, including net operating loss carryforwards and research and development tax credits, the Company has a partial valuation allowance reserved against such assets. The Company intends to continue to maintain a partial valuation allowance on the deferred tax assets until there is sufficient evidence to support the reversal of all or some additional portion of these allowances.
Due to the net operating loss carryforwards, all of the Company's United States federal and a majority of its state returns are open to examination by the Internal Revenue Service and state jurisdictions for all years since inception. The 2017 U.S. Income Tax Return for Telaria, Inc. was under examination by the IRS, which was closed during the period ended June 30, 2021 with no change to tax as reported. For the Netherlands and the United Kingdom, all tax years remain open for examination by the local country tax authorities, for France only 2018 forward are open for examination, for Singapore 2017 and forward are open for examination, for Australia, Brazil, Canada, Germany, Italy, New Zealand, and Malaysia 2016 and forward are open for examination, and for Japan 2014 and forward remain open for examination.
Pursuant to Section 382 of the Internal Revenue Code, the Company and Telaria, Inc. both underwent ownership changes for tax purposes (i.e. a more than 50% change in stock ownership in aggregated 5% shareholders) on April 1, 2020 due to the Telaria Merger. As a result, the use of our total domestic NOL carryforwards and tax credits generated prior to the ownership change will be subject to annual use limitations under Section 382 and Section 383 of the Code and comparable state income tax laws. The Company believes that the ownership change will not impact our ability to utilize substantially all of our NOLs and state research and development carryforward tax credits to the extent it will generate taxable income that can be offset by such losses. The Company reasonably expects its federal research and development carryforward tax credits will not be recovered prior to expiration.
There was no material change to the Company's unrecognized tax benefits in the nine months ended September 30, 2021 and the Company does not expect to have any material changes to unrecognized tax benefits through the end of the fiscal year.
Note 11—Lease Obligations
For the three months ended September 30, 2021 and 2020, the Company recognized $4.9 million and $3.7 million, respectively, and $15.7 million and $9.7 million during the nine months ended September 30, 2021 and 2020, respectively, of lease expense under ASC 842, which included operating lease expenses associated with leases included in the lease liability and ROU asset on the condensed consolidated balance sheet. In addition, for the three months ended September 30, 2021 and 2020, the
24

Company recognized $0.4 million and $0.4 million, respectively, and $1.0 million and $0.8 million during the nine months ended September 30, 2021 and 2020, respectively, of lease expense related to short-term leases, and $9.9 million and $5.6 million during the three months ended September 30, 2021 and 2020, respectively, and $24.6 million and $14.0 million during the nine months ended September 30, 2021 and 2020, respectively, of variable and cloud-based services related to data centers that are not included in the ROU asset or lease liability balances. As part of restructuring activities associated with the SpotX Acquisition, during the nine months ended September 30, 2021, the Company recognized $2.5 million of lease related loss contracts, which is included in the lease expense under ASC 842.
The Company also received rental income of $1.0 million and $1.2 million for real estate leases for which it subleases the property to third parties during the three months ended September 30, 2021 and 2020, respectively and $3.3 million and $2.5 million for the nine months ended September 30, 2021 and 2020, respectively.
As of September 30, 2021, a weighted average discount rate of 5.05% has been applied to the remaining lease payments to calculate the lease liabilities included within the condensed consolidated balance sheet. The lease terms of the Company’s operating leases generally range from one year to ten years, and the weighted average remaining lease term of leases included in the lease liability is 6.34 years as of September 30, 2021.
The maturity of the Company's lease liabilities associated with leases included in the lease liability and ROU asset were as follows as of September 30, 2021 (in thousands):
Fiscal Year

Note 12—Commitments and Contingencies
Commitments
The Company has commitments under non-cancelable operating leases for facilities, certain equipment, and its managed data center facilities (Note 11).
As of September 30, 2021 and December 31, 2020, the Company had $5.1 million and $6.3 million, respectively, of letters of credit associated with office leases available for borrowing, on which there were no outstanding borrowings as of either date.
Guarantees and Indemnification
    The Company’s agreements with sellers, buyers, and other third parties typically obligate the Company to provide indemnity and defense for 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 the Company’s own business operations, obligations, and acts or omissions. However, under some circumstances, the Company agrees 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. For example, because the Company’s business interposes the Company between buyers and sellers in various ways, buyers often require the Company to indemnify them against acts and omissions of sellers, and sellers often require the Company to indemnify them against acts and omissions of buyers. In addition, the Company’s agreements with sellers, buyers, and other third parties typically include provisions limiting the Company’s liability to the counterparty, and the counterparty’s liability to the Company. These limits sometimes do not apply to certain liabilities, including indemnity obligations. These indemnity and limitation of liability provisions generally survive termination or expiration of the agreements in which they appear. The Company has also entered into indemnification agreements with its directors, executive officers, and certain other officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers, or employees. No material demands have been made upon the Company to provide indemnification under such agreements and there are no claims that the Company is aware of that could have a material effect on the Company’s consolidated financial statements.
Litigation
25

The Company and its subsidiaries may from time to time be parties to legal or regulatory proceedings, lawsuits and other claims incident to their business activities and to the Company’s status as a public company. Such matters may include, among other things, assertions of contract breach or intellectual property infringement, claims for indemnity arising in the course of the Company’s business, regulatory investigations or enforcement proceedings, and claims by persons whose employment has been terminated. Such matters are subject to many uncertainties, and outcomes are not predictable with assurance. Consequently, management is unable to ascertain the ultimate aggregate amount of monetary liability, amounts which may be covered by insurance or recoverable from third parties, or the financial impact with respect to such matters as of September 30, 2021. However, based on management’s knowledge as of September 30, 2021, management believes that the final resolution of these matters known at such date, individually and in the aggregate, will not have a material adverse effect upon the Company’s consolidated financial position, results of operations or cash flows.
Employment Contracts
The Company has entered into severance agreements with certain employees and officers. The Company may be required to pay severance and accelerate the vesting of certain equity awards in the event of involuntary terminations.

Note 13—SVB Loan Agreement
On September 25, 2020, the Company amended and restated its loan and security agreement with Silicon Valley Bank ("SVB") (the "Loan Agreement"), which was scheduled to expire on September 26, 2020. The Loan Agreement provided a senior secured revolving credit facility of up to the lesser of $60.0 million and 85% of eligible accounts receivable, with a maturity date of September 25, 2022. The Loan Agreement included a letter of credit, foreign exchange and cash management facility with a sublimit up to $10.0 million. On April 30, 2021, the Company entered into the Credit Agreement, as defined in Note 15. In connection with entering into the Credit Agreement, the Loan Agreement with SVB was terminated on April 30, 2021. As of April 30, 2021, there were no amounts outstanding under the Loan Agreement.

Note 14—Convertible Senior Notes and Capped Call Transactions
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 total net proceeds from the offering, after deducting debt issuance costs, paid by the Company, were approximately $388.6 million. The Company used approximately $39.0 million of the net proceeds from the offering to pay for the Capped Call Transactions (as described below).
The Convertible Senior Notes are senior, unsecured obligations and (i) will be equal in right of payment with the existing and future senior, unsecured indebtedness; (ii) senior in right of payment to any of the Company’s future indebtedness that is expressly subordinated to the Convertible Senior Notes; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, to the extent of the value of the collateral securing that indebtedness, including amounts outstanding under our Existing Loan Agreement or our New Credit Facilities (see Note 15); and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent we are not a holder thereof) preferred equity, if any, of the Company’s subsidiaries that do not guarantee the Convertible Senior Notes.
The Convertible Senior Notes accrue interest at 0.25% per annum payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2021. The Convertible Senior Notes will mature on March 15, 2026 unless they are redeemed, repurchased or converted prior to such date. The Convertible Senior Notes are convertible at the option of holders only during certain periods and upon satisfaction of certain conditions.
Holders will have the right to convert their notes (or any portion of a note in an authorized denomination), in the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021, if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (ii) during the five consecutive business days immediately after any ten consecutive trading day period (such ten consecutive trading day period, the "measurement period") in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on such trading day; (iii) upon the occurrence of certain corporate events or distributions on the Company’s common stock; (iv) if the Company calls such Convertible Senior Notes for redemption; and (v) on or after September 15, 2025, until the close of business on the second scheduled trading day immediately before the maturity date, holders of the Convertible Senior Notes may, at their option, convert all or a portion of their Convertible Senior Notes regardless of the foregoing conditions.at any time from, and including, September 15, 2025 until the close of business on the second scheduled trading day immediately before the maturity date.
26

Upon conversion, the Convertible Senior Notes may be settled in shares of the Company’s common stock, cash or a combination of cash and shares of the Company’s common stock, at the Company’s election. All conversions with a conversion date that occurs on or after September 15, 2025 will be settled using the same settlement method, and the Company will send notice of such settlement method to noteholders no later than the open of business on September 15, 2025.
The Company may not redeem the Convertible Senior Notes at their option at any time before March 20, 2024. Subject to the terms of the indenture, the Company has the right, at its election, to redeem all, or any portion (subject to the partial redemption limitation) in an authorized denomination, of the Convertible Senior Notes, at any time, and from time to time, on a redemption date on or after March 20, 2024 and on or before the 40th scheduled trading day immediately before the maturity date, for cash, but only if the "last reported sale price," as defined under the Offering Memorandum, per share of common stock exceeds 130% of the “conversion price” on (i) each of at least 20 trading days, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (ii) the trading day immediately before the date we send such notice. In addition, calling any note for redemption will constitute a "make-whole fundamental change" (as defined below) with respect to that note, in which case the conversion rate applicable to the conversion of that note will be increased in certain circumstances if it is converted after it is called for redemption. If the Company elects to redeem less than all of the outstanding notes, then the redemption will not constitute a make-whole fundamental change with respect to the notes not called for redemption, and holders of the notes not called for redemption will not be entitled to an increased conversion rate for such notes as described above on account of the redemption, except to the limited extent described further below. No sinking fund is provided for the Convertible Senior Notes, which means that the Company is not required to redeem or retire the Convertible Senior Notes periodically.
If a fundamental change occurs, then each noteholder will have the right to require the Company to repurchase its notes (or any portion thereof in an authorized denomination) for cash on a date (the "fundamental change repurchase date") of the Company’s choosing, which must be a business day that is no more than 45, nor less than 20, business days after the date Magnite distributes the related fundamental change notice.
If an event of default occurs with respect to the Company or any guarantor, then the principal amount of, and all accrued and unpaid interest on, all of the notes then outstanding will immediately become due and payable without any further action or notice by any person. If an event of default (other than an event of default described below with respect to Magnite or any guarantor and not solely with respect to a significant subsidiary of the Company’s or a guarantor, other than the Company or such guarantor) occurs and is continuing, then, except as described below under the caption —Special interest as sole remedy for certain reporting defaults, the trustee, by notice to the Company, or noteholders of at least 25% of the aggregate principal amount of notes then outstanding, by written notice to us and the trustee, may declare the principal amount of, and all accrued and unpaid interest on, all of the notes then outstanding to become due and payable immediately.
The Convertible Senior Notes have an initial conversion rate of 15.6539 shares of common stock per $1,000 principal amount of the Convertible Senior Notes, which will be subject to customary anti-dilution adjustments in certain circumstances.
In connection with the pricing of the Convertible Senior Notes, the Company entered into privately negotiated capped call transactions with various financial institutions (the "Capped Call Transactions"). The Capped Call Transactions were entered into with third party broker-dealers to limit the potential dilution that would occur if the Company has to settle the conversion value in excess of the principal in shares. This exposure will be covered (i.e., the Company will receive as many shares as are required to be issued between the conversion price of $63.8818 and the maximum price of $91.2600). Any shares required to be issued by the Company over this amount would have net earnings per share dilution impact. By entering into the Capped Call Transactions, the Company expects to reduce the potential dilution to its common stock (or, in the event the conversion is settled in cash, to reduce its cash payment obligation) in the event that at the time of conversion its stock price exceeds the conversion price under the Convertible Senior Notes. The Company paid $39.0 million for the Capped Call Transactions, which was recorded as additional paid-in capital, using a portion of the gross proceeds from the sale of the Convertible Senior Notes. The cost of the Capped Call Transactions is not expected to be tax deductible as the Company did not elect to integrate the capped call into the Convertible Senior Notes for tax purposes. The cost of the Capped Call Transaction was recorded as a reduction of the Company’s additional paid-in capital in the accompanying condensed consolidated financial statements.
As noted in Note 1, the Company early adopted ASU 2020-06 effective January 1, 2021. The Company has not elected the fair value option, the embedded conversion features are not required to be bifurcated under the accounting guidance, and the convertible debt was not issued with a substantial premium. As such, the Company accounted for the Convertible Senior Notes as a liability in its entirety. Under the guidance, all the embedded features of the Convertible Senior Notes met the definition of a derivative. These features included a contingent call option, contingent put options, and conversion features. The contingent call option and contingent put options are clearly and closely related to the debt host and, therefore, do not require bifurcation. As the conversion features are indexed to the Company’s own equity and would be equity classified if they were freestanding instruments, the scope exception in ASC 815-10-15-74(a) applies and these conversion features will not be bifurcated under ASC 815.
27

The new accounting guidance also eliminated the bifurcation models of ASC 470-20 and eliminated the treasury method approach to earnings per share. Accordingly, earnings per share on convertible debt instruments should only be calculated under the If-Converted method. Under the guidance above, the Company will assume settlement in shares.

Note 15—Credit Facility
On April 30, 2021, the Company entered into a credit agreement (the "Credit Agreement") with Goldman Sachs Bank USA as administrative agent and collateral agent, and other lender parties thereto. The Credit Agreement provides 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"). 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. Loans, if any, under the Revolving Credit Facility are expected to be used for general corporate purposes. The obligations under the Credit Agreement are secured by substantially all of the assets of the Company and those of its subsidiaries that are guarantors under the Credit Agreement.
Amounts outstanding under the Credit Agreement accrue interest at a rate equal to either, (1) for the Term Loan B Facility, at the Company’s election, the Eurodollar Rate (as defined in the Credit Agreement) plus a margin of 5.00% per annum, or ABR (as defined in the Credit Agreement) plus a margin of 4.00%, and (2) for the Revolving Credit Facility, at the Company’s election, the Eurodollar Rate plus a margin of 4.25% to 4.75%, or ABR plus a margin of 3.25% to 3.75%, in each case, depending on the Company’s first lien net leverage ratio.
The covenants of the Credit Agreement include customary negative covenants that, among other things, restrict the Company’s ability to incur additional indebtedness, grant liens and make certain acquisitions, investments, asset dispositions and restricted payments. In addition, the Credit Agreement contains a financial covenant, tested on the last day of any fiscal quarter if
28

utilization of the Revolving Credit Facility exceeds 35% of the total revolving commitments, that requires the Company to maintain a first lien net leverage ratio not greater than 3.25 to 1.00.
The Credit Agreement includes customary events of default, and customary rights and remedies upon the occurrence of any event of default thereunder, including rights to accelerate the loans, terminate the commitments thereunder and realize upon the collateral securing the obligations under the Credit Agreement. The Credit Agreement calls for customary scheduled loan amortization payments of 0.25% of the initial principal balance payable quarterly (i.e. 1% in aggregate per year) as well as a provision that requires the Company to prepay the Term Loan B based on a calculation of cumulative free cash flow generated by the company as defined within the terms of the Agreement.
On June 28, 2021, the Company entered into an Incremental Assumption Agreement (the "Incremental Agreement") to the Credit Agreement. Pursuant to the terms of the Incremental Agreement, the Company’s existing revolving credit facility under the Credit Agreement was increased by $12.5 million (the "Incremental Revolver"), and the letter of credit sublimit under the Credit Agreement was increased by $5.0 million. The Incremental Revolver bears the same interest rate as the existing revolving credit facility and has the same maturity date as the existing revolving credit facility. No other terms of the Credit Agreement were amended. As a result, amounts available under the Revolving Credit Facility were $65.0 million. At September 30, 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.

Note 16—Subsequent Events
Subsequent to September 30, 2021, the Company entered into a data center contract renewal, with future commitments of approximately $2.2 million per year over 3.0 years, beginning on December 1, 2021.
On October 20, 2021, the Company granted 91,582 restricted stock units to the Company's employees. Of the RSUs granted, 25,557 will vest over four years from issuance with 25% after one year, and the remainder vesting quarterly thereafter, and 66,025 will vest 50% on October 1, 2022 and 50% October 1, 2023.

Overview
Magnite, Inc., formerly known as The Rubicon Project, Inc. ("we," or "us"), provides technology solutions to automate the purchase and sale of digital advertising inventory.
On April 1, 2020, we completed a stock-for-stock merger with Telaria, Inc. ("Telaria" and such merger the "Telaria Merger"), a leading provider of connected television ("CTV") technology, and on April 30, 2021, we completed the acquisition of SpotX, Inc. ("SpotX" and such acquisition the "SpotX Acquisition"), a leading platform shaping CTV and video advertising globally.
Following the Telaria Merger and SpotX Acquisition, we believe that we are the world’s largest independent omni-channel sell-side advertising platform, offering a single partner for transacting globally across all channels, formats and auction types, and the largest independent programmatic CTV marketplace, making it easier for buyers to reach CTV audiences at scale from industry-leading streaming content providers, broadcasters, platforms and device manufacturers.
Our platform features applications and services for sellers of digital advertising inventory, or publishers, that own and operate CTV channels, applications, websites 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, ("DSPs"), 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. Our clients include many of the world’s leading buyers and sellers of digital advertising inventory. Our platform processes trillions of ad requests per month allowing buyers access to a global, scaled, independent alternative to "walled gardens," who both own and sell inventory and maintain control on the demand side.
We provide a full suite of tools for sellers to control their advertising business and protect the consumer viewing experience. These tools are particularly important to CTV sellers who need to ensure a TV-like viewing and advertising experience for consumers. For instance, our "ad-pod" feature provides publishers with a tool analogous to commercial breaks in traditional linear television so that they can request and manage several ads at once from different demand sources. Using this tool, publishers can establish business rules such as competitive separation of advertisers to ensure that competing brand ads do not appear during the same commercial break. In addition, we offer audio normalization tools to control for the volume of an ad relative to content, frequency capping to avoid exposing viewers to repetitive ad placements, and creative review so that a publisher can review and approve the ad units being served to its properties.
On July 1, 2021, we acquired SpringServe, LLC ("SpringServe"), a leading ad serving platform for CTV. SpringServe's ad serving technology manages multiple aspects of video advertising, including for CTV publishers, across both their programmatic and direct-sold inventory, including forecasting, routing, customized ad experiences, and advanced podding logic. The integration of SpringServe’s ad serving technology with our existing programmatic SSP capabilities provides CTV publishers a holistic yield management solution that dynamically allocates between direct-sold and programmatic inventory to drive value.
Buyers leverage our platform to manage their advertising spend and reach their target audiences on brand-safe premium inventory, simplify order management and campaign tracking, obtain actionable insights into audiences for their advertising, and access impression-level purchasing from thousands of sellers. We believe that our scale, platform features, and omni-channel offering makes us an essential partner for buyers.
We operate our business on a worldwide basis, with an established operating presence in North America, Australia and Europe, and a developing presence in Asia and South America. Our non-U.S. subsidiaries and operations perform primarily sales, marketing, and service functions.
Our global workforce has maintained a work from-home policy since March, 2020. We continue to monitor best practices and guidance for a potential return to office and currently plan to return to our offices in most locations during the first quarter of 2022. We will approach our return with caution to prioritize the safety and health of our employees. We believe that our employees have been able to work productively during the time period in which our global offices have been shut down. However, to the extent we have extended work from home requirements, or that work patterns are permanently altered, it is unclear how productivity may be impacted in the long-term.
How We Generate Revenue
We generate revenue from the use of our platform for the purchase and sale of digital advertising inventory. 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. 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.
Digital advertising inventory is created when consumers access sellers' content. Sellers provide digital advertising inventory to our SSP 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
34

paid impressions, for the seller to present to the consumer. The price that buyers pay for each thousand paid impressions purchased is measured in units referred to as CPM, or cost per thousand, and the total volume of spending between buyers and sellers on our platform is referred to as advertising spend.
Industry Trends
Continued Shift Toward Digital Advertising
Consumers are rapidly shifting their viewing habits towards digital mediums and expect to be able to consume content seamlessly across multiple devices, including computers, tablets, smartphones, and CTVs whenever and wherever they want. As digital content consumption continues to proliferate, we believe the percentage of advertising dollars spent through digital channels will continue to grow.
Automation of Buying and Selling
Due to the size and complexity of the advertising ecosystem and purchasing process, manual processes cannot effectively manage digital advertising inventory at scale. In addition, both buyers and sellers are demanding more transparency, better controls and more relevant insights from their advertising inventory purchases and sales. This has created a need for software solutions, known as programmatic advertising, that automate the process for planning, buying, selling and measuring digital advertising across screens. Programmatic buying enables the use of real-time bidding technology that allows for the dynamic purchase and sale of advertising inventory on an impression-by-impression basis. Programmatic transactions include open auctions, where multiple buyers bid against each other in a real-time auction for the right to purchase a publisher's inventory, as well as reserve auctions, where publishers establish direct deals or private marketplaces with select buyers. Programmatic has become the dominant method of transacting for desktop and mobile inventory and we expect it to continue to grow as a percentage of CTV advertising.
Convergence of TV and Digital
CTV viewership is growing rapidly and the pace of adoption is accelerating the transition of linear television to CTV programming. As the number of CTV channels continues to proliferate, we believe that ad-supported models or hybrid models that rely on a combination of subscription fees and advertising revenue will continue to gain traction. In turn, we believe brand advertisers looking to engage with streaming viewers will continue to shift their budgets from linear to CTV. Furthermore, as the CTV market continues to mature, we believe that a greater percentage of CTV advertising inventory will be sold programmatically, similar to trends that occurred in desktop and mobile. As such, we expect CTV to be a significant driver of our revenue growth for the foreseeable future. We expect the recently completed acquisitions of SpotX and SpringServe to further fuel this growth.
Identity Solutions
A number of participants in the advertising technology ecosystem have taken or are expected to take action to eliminate or restrict the use of third-party cookies and other primary identifiers that have historically been used to deliver targeted advertisements. We believe that the elimination of third-party cookies has the potential to shift the programmatic ecosystem from an identity model powered by buyers that are able to aggregate and target audiences through cookies to one enabled by sellers that have direct relationships with consumers and are therefore better positioned to obtain user data and consent for implementing first party identifiers. We believe that our platform and scale position us well to provide the infrastructure and tools needed for a publisher-centric identity model to succeed, and we are already enabling sellers to create audience segments with their first-party data.
Supply Path Optimization
Supply Path Optimization ("SPO") refers to efforts by buyers to consolidate the number of vendors with which they work to find the most effective and cost-efficient paths to procure media. SPO is important to buyers because it can increase the proportion of their advertising ultimately spent on working media, with the goal of increasing return on their advertising spend, and can help them gain efficiencies by reducing the number of vendors with which they work in a complex ecosystem. We believe we are well positioned to benefit from SPO in the long run as a result of our transparency, our broad and unique inventory supply across all channels and formats, including CTV, buyer tools, such as traffic shaping that reduce the cost of working with us, and our brand safety measures.
Header Bidding and Data Processing
Header bidding is a programmatic technique by which sellers offer inventory to multiple ad exchanges and supply side platforms, such as our platform, simultaneously. Header bidding has been rapidly adopted in recent years in the desktop and mobile channels, and while the rise and rapid adoption of header bidding increased revenue for sellers, it has also created new challenges and technical complexities. Header bidding has led to a significant increase in the number of ad impressions to be processed and analyzed through our platform as well as by DSPs, which can lead to increased costs if not properly addressed. We have invested in technology solutions, such as Demand Manager, to help publishers manage their header-bidding inventory.
35

Privacy Regulation
Our business is highly susceptible to emerging privacy regulations and oversight concerning the collection, use and sharing of data. Data protection authorities in a number of territories have expressed a desire to focus on the advertising technology ecosystem. In particular, this scrutiny has focused on the use of technology (including cookies) to collect or aggregate information about Internet users’ online browsing activity. Because we, and our clients, rely upon large volumes of such data, it is essential that we monitor developments in this area domestically and globally, and engage in responsible privacy practices.
The use of and transfer of personal data in EEA member states and the UK is currently governed by the General Data Protection Regulation (the "GDPR"). The GDPR sets out higher potential liabilities for certain data protection violations and establishes significant new regulatory requirements resulting in a greater compliance burden for us in the course of delivering our solution in the EEA and UK. While data protection authorities have started to clarify certain requirements under GDPR, significant uncertainty remains as to how the regulation will be applied and enforced.
In addition to the GDPR, a number of new privacy regulations will or have already come into effect. The California legislature passed the California Consumer Privacy Act ("CCPA") in 2018, which became effective January 1, 2020. This law imposes new obligations on businesses that handle the personal information of California residents. The obligations imposed require us to maintain ongoing significant resources for compliance purposes. Certain requirements remain unclear due to ambiguities in the drafting of or incomplete guidance. Adding to the uncertainty facing the ad tech industry, a new law, titled the California Privacy Rights Act ("CPRA") passed as a ballot initiative in California and will impose additional notice and opt out obligations on the digital advertising space. This law, which will take effect in January 2023, is expected to cause us to incur additional compliance costs and impose additional restrictions on us and on our industry partners. These ambiguities and resulting impact on our business will need to be resolved over time. In addition, other privacy bills have been introduced at both the state and federal level. Certain international territories are also imposing new or expanded privacy obligations. In the coming years, we expect further consumer privacy regulation worldwide.
We support privacy initiatives and believe they will be beneficial to consumers' confidence in advertising technology, which will ultimately be positive for the advertising ecosystem in the long term. In the short term, however, until prevailing compliance practices standardize, the impact of worldwide privacy regulations on our business and, consequently, our revenue could be negatively impacted.

Trends in Our Business
Telaria Merger, SpotX and SpringServe Acquisitions
On April 1, 2020, we completed the Telaria Merger, on April 30, 2021, we completed the SpotX Acquisition and on July 1, 2021, we completed the SpringServe Acquisition. These transactions were transformative and have resulted in what we believe to be the world’s largest independent sell-side advertising platform, 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 growth 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. As a result of the transaction, we expect CTV to represent a higher percentage of our overall revenue, and because CTV is largely transacted through reserve auctions, we also expect to see an increase in the percentage of reserve auction transactions transacted on our platform. The acquisition will result in an increase in related operating expenses, primarily associated with costs for personnel, 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 September 30, 2021, we have achieved more than half of our cost synergy target on a run-rate basis.
The SpringServe Acquisition 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 remain below pre-COVID spending levels. In the third quarter, 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. We expect such challenges to persist throughout the remainder of 2021 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.

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. We also generate revenue from the fee we charge clients for use of our Demand Manager product and SpringServe ad server product, which we acquired on July 1, 2021. 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. 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 has increased significantly. 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 September 30, 2021, our revenue reported on a gross basis increased to 20% 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 excluding traffic and acquisition cost ("TAC"), as defined in section "Key Operating and Financial Performance Metrics"). Our revenue recognition policies are discussed in more detail in our audited consolidated financial statements and notes thereto for the year ended December 31, 2020 included in our Annual Report on Form 10-K and in Note 3 of the accompanying Notes to the Condensed 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 TAC. 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
38

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 Three and Nine Months Ended September 30, 2021 and 2020
    Revenue
Revenue increased $70.9 million, or 116%, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020. Our revenue growth was driven primarily by increases in our core business as well as incremental revenue from the SpotX Acquisition, which was completed on April 30, 2021. On a pro forma basis, including SpotX and SpringServe revenue for the three months ended September 30, 2020, revenue increased 27% for the three months ended September 30, 2021 compared to the prior period, primarily due to the growth in all channels, mainly driven by CTV and mobile, and a rebound from impacts of the COVID-19 pandemic.
Revenue increased $167.5 million, or 120%, for the nine months ended September 30, 2021 compared to the prior year period, for the same reasons above plus incremental contributions from the Telaria Merger, which was completed on April 1, 2020. On a pro forma basis, including revenue for SpringServe, SpotX, and Telaria during the relevant pre-acquisition period, revenue increased 47%, for the nine months ended September 30, 2021 compared to the prior year period.
We expect our revenue will substantially increase through the remainder of 2021 as a result of our recent Acquisitions and from continued growth in other areas of our business, in particular CTV. 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. For instance, an increase in reserve auction transactions as a percentage of the transactions on our platform could also result in reduced revenue, if not offset by increased advertising spend, because reserve auction transactions can carry lower take rates than open auction transactions. We believe that contributions to revenue from reserve auction, 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 result in an overall increase in advertising spend through our platform and in revenue due to both an increase in volume and average CPM which will be partially offset by a decrease in our average take rate.
Cost of Revenue
Cost of revenue increased $42.5 million, or 202%, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020, primarily due to costs associated with our revenue growth, and an increase in traffic acquisition cost driven by the increase in revenue reported on a gross basis as a result of the SpotX Acquisition. Cost of revenue increased by $17.0 million in traffic acquisition costs associated with revenue recognized on a gross basis, $15.2 million in depreciation and amortization, and $6.6 million in data and bandwidth expenses during the three months ended September 30, 2021 compared to the same period in the prior year.
For the nine months ended September 30, 2021, cost of revenue increased $78.2 million, or 138%, compared to the prior year period primarily due to the same reasons above, as well as increased costs from the Telaria Merger, which was completed on April 1, 2020. Cost of revenue increased by $31.6 million in traffic acquisition costs associated with revenue recognized on a gross
41

basis, $25.7 million in depreciation and amortization, and $15.1 million in data and bandwidth expenses during the nine months ended September 30, 2021 compared to the same period in the prior year.
Our cost of revenue will continue to increase in future periods as a result of our recent acquisitions. In addition, excluding the impact of recent acquisitions, we expect our cost of revenue to increase on a year-over-year basis through the remainder of 2021 due primarily to the increase in expenses due to a full year of amortization of intangible assets resulting from the Telaria Merger and higher cloud service costs to support the growth of our business.
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 $30.5 million, or 140%, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020, primarily due to the SpotX Acquisition and associated increases in headcount and the amortization of acquired intangibles and other assets. Sales and marketing expenses increased by $19.3 million related to depreciation and amortization and by $10.5 million related to personnel expenses, both increases associated with the SpotX Acquisition.
For the nine months ended September 30, 2021, sales and marketing expenses increased $65.1 million, or 123%, compared to the prior year period for the same reasons above. Sales and marketing expenses increased by $35.1 million related to depreciation and amortization and by $27.9 million related to personnel expenses, both increases associated with the SpotX Acquisition and the Telaria Merger.
We expect sales and marketing expenses will continue to increase on a year-over-year basis through the remainder of 2021 due to increase in our headcount associated with our recent acquisitions, increases in travel and entertainment related expenses, as well as a full year of amortization of intangible assets resulting from the Telaria Merger, and amortization of acquired intangible assets as a result of the SpotX Acquisition, partially offset by reductions associated with cost synergies.
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 $7.5 million, or 55%, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020, due primarily to an increase of $7.1 million in personnel costs as a result of the increased headcount associated with the SpotX Acquisition.
For the nine months ended September 30, 2021, technology and development expenses increased $16.1 million, or 43%, compared to the prior year period, due to an increase of $15.5 million in personnel costs primarily for the same reasons above as well as the Telaria Merger.
We expect technology and development expenses to continue to increase on a year-over-year basis through the remainder of 2021 due to increase in our headcount associated with our recent acquisitions, partially offset by reductions associated with cost synergies.
The timing and amount of our capitalized development and enhancement projects may affect the amount of 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 $3.2 million, or 24%, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020, primarily due to increases of $1.6 million in personnel expenses primarily associated with the SpotX Acquisition.
For the nine months ended September 30, 2021, general and administrative expenses increased $9.5 million, or 25%, compared to the prior year period, primarily due to increases of $4.6 million in personnel expenses, $2.0 million in professional services, and $0.9 million in software licenses, for the same reasons above.
We expect general and administrative expenses will continue to increase on a year-over-year basis through the remainder of 2021 due our recent acquisitions, partially offset by reductions associated with cost synergies.
42

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 increased by $0.2 million, or 8%, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020. Costs incurred during the three months ended September 30, 2021 of $2.4 million were primarily due to the SpotX and SpringServe Acquisitions, which were completed on April 30, 2021 and July 1, 2021, respectively, which costs included investment banking advisory, legal, and other professional services fees, one-time cash-based employee termination benefit costs, and non-cash stock-based compensation expense associated with equity accelerations due to severance benefits. Costs incurred during the three months ended September 30, 2020 of $2.3 million were primarily due to the Telaria Merger, which was completed on April 1, 2020, which costs included investment banking advisory, legal, and other professional services fees, one-time cash-based employee termination benefit costs, and non-cash stock-based compensation expense associated with double-trigger accelerations.
Merger, acquisition, and restructuring costs increased by $21.1 million, or 127%, for the nine months ended September 30, 2021 compared to the prior year period for the same reasons above as well as facility closure costs associated with office space restructuring activities.
We expect to continue to incur merger, acquisition, and restructuring costs to continue to increase on a year-over-year basis through the remainder of 2021 as a result of the SpotX and SpringServe Acquisitions and related restructuring activities.

Total other (income) expense, net $ 5,079  $ (871) $ 7,920  $ (3,444)
Interest (income) expense, net increased by $7.3 million and $12.7 million during the three and nine months ended September 30, 2021, respectively, compared to the same periods in 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.
We expect interest expense to increase in 2021 compared to 2020 significantly as a result of increase in interest expense associated with our Convertible Senior Notes and Term Loan B Facility.
Foreign exchange (gain) loss, net is impacted by movements in exchange rates and the amount of foreign currency-denominated cash, receivables, payables, and intercompany balances, which are impacted by our billings to buyers and payments to sellers. During the three and nine months ended September 30, 2021, the net foreign exchange gain was primarily attributable to the currency movements between the British Pound, Australian Dollar, Canadian Dollar, and the Euro relative to the U.S. Dollar.

Provision (Benefit) for Income Taxes     
    We recorded an income tax benefit of $4.7 million and expense of $0.4 million for the three months ended September 30, 2021 and 2020, respectively and an income tax benefit of $92.2 million and expense of $0.5 million for the nine months ended September 30, 2021 and 2020, respectively. The tax benefit for the three and nine months ended September 30, 2021 is primarily the result of the partial release of the domestic valuation allowance of $56.2 million related to the SpotX Acquisition, as well as the income tax benefit of a portion of our current year projected loss. The net deferred tax liabilities recorded in connection with the SpotX and SpringServe Acquisitions provided an additional source of taxable income to support the realizability of pre-existing deferred tax assets, and, as a result, we released a portion of our domestic valuation allowance and recognized current benefit for a portion of our projected losses. We continue to maintain a partial valuation allowance for our domestic deferred tax assets.

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."

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. We believe 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 three and nine months ended September 30, 2021 and 2020, respectively:

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 ex-TAC across channels to better understand how our clients are transacting on our platform, which informs decisions as to business strategy and the allocation of resources and capital. The following table presents Revenue ex-TAC by channel.

Revenue ex-TAC increased $53.8 million, or 89%, for the three months ended September 30, 2021 compared to the three months ended September 30, 2020. The increase in Revenue ex-TAC is due to increases across all channels, a rebound from COVID-19 advertising lows, and includes increases associated with the SpotX Acquisition, which was completed on April 30 2021.
Revenue ex-TAC increased $135.7 million, or 98%, for the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. The increase in Revenue ex-TAC is attributable to the same reasons above.
We expect Revenue ex-TAC to increase through the remainder of 2021 as compared to the same period in the prior year. We believe that CTV will be our biggest growth driver in future periods and with the recently completed SpotX Acquisition, we expect CTV Revenue ex-TAC to represent a significantly higher percentage of our overall Revenue ex-TAC.
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 our mobile application business has been the growth driver behind our mobile business. We therefore expect our 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 ex-TAC 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 ex-TAC in the near term. Therefore, the mix of our desktop business will continue to dampen our overall growth rate.
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.
45

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 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-operational 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.

Adjusted EBITDA increased by $26.2 million during the three months ended September 30, 2021 compared to the three months ended September 30, 2020, primarily due to increase in revenue from both organic growth and the SpotX and SpringServe Acquisitions, which are discussed in section "Comparison of the "Three and Nine Months Ended September 30, 2021 and 2020," and improved operating leverage from our increased scale and related cost synergies.
Adjusted EBITDA increased by $68.1 million during the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020, for the same reasons above.
We expect Adjusted EBITDA to continue to increase as a result of continued growth in revenue and the realization of additional cost synergies.

Liquidity and Capital Resources
Liquidity
As of September 30, 2021, we had an aggregate gross principal amount of $759.1 million of indebtedness outstanding that will mature in 2021 through 2028, and approximately $59.9 million of availability to borrow under our Revolving Credit Facility. See Note 14 "Convertible Senior Notes and Capped Call Transactions" and Note 15 "Credit Facility" in the notes to unaudited condensed consolidated financial statements included in this Quarterly Report for further information about our outstanding debt. Our ability to meet expenses, remain in compliance with the covenants under our debt instruments, pay interest, repay principal for our level of indebtedness 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. Additionally, our cash flows may not be sufficient to allow us to pay interest or repay principal on our outstanding indebtedness.
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. As of September 30, 2021, we had cash and cash equivalents of $188.2 million, of which $34.2 million was held in foreign currency denominated cash accounts. Our cash and cash equivalents are managed with the objective of preserving principal and maintaining liquidity while minimizing risk. We also have an undrawn Revolving Credit Facility of $65.0 million, of which approximately $5.1 million is assigned to outstanding but undrawn letters of credit. Our principal cash requirements are to fund business operations and working capital needs, taxes, interest and principal payments, and capital expenditures. 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. Additionally, we must continue to reinvest in our business by making capital expenditure investments which tend to be higher in the second half of the year. These impacts from working capital, cash conversion cycle and capital expenditures can significantly impact our cash flows from operating and investing activities and therefore, our liquidity during any period presented.
We believe our existing cash and cash equivalents, investment balances, 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. For example, we typically collect from buyers in advance of payments to sellers, and our collection and payment cycle can vary from period to period depending upon various circumstances, including seasonality. In addition, in the event a buyer defaults on payment, we may still be required to pay sellers for the inventory purchased even if we are unable to collect from buyers. To date, these actions have not had a material negative impact on our cash flow or liquidity. The future capital requirements and the adequacy of available funds will depend on many factors, including the duration and severity of the COVID-19 pandemic and its impact on buyers and sellers and the factors and those set forth in Part II, Item 1A: "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2020.
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 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 September 30, 2021, the balance of the Convertible Debt was $389.8 million, net of unamortized debt issuance costs of $10.2 million. Accrued interest at September 30, 2021 was $0.5 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 14 "Convertible Senior Notes and Capped Call Transactions" in the notes to unaudited condensed consolidated financial statements included in this Quarterly Report 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
47

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"). 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.
On June 28, 2021, we entered into an Incremental Assumption Agreement (the "Incremental Agreement") to the Credit Agreement. Pursuant to the terms of the Incremental Agreement, the Company’s existing revolving credit facility under the Credit Agreement was increased by $12.5 million (the "Incremental Revolver") to $65.0 million total, and the letter of credit sublimit under the Credit Agreement was increased by $5.0 million. At September 30, 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.
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 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 marketable securities balances are 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:
Nine Months Ended
September 30, 2021 September 30, 2020
(in thousands)
Cash flows provided by (used in) operating activities $ 58,000  $ (24,038)
Cash flows (used in) provided by investing activities (675,570) 43,490 
Cash flows provided by (used in) financing activities 688,863  (3,280)
Effects of exchange rate changes on cash, cash equivalents and restricted cash (591) 41 
Change in cash, cash equivalents and restricted cash $ 70,702  $ 16,213 
    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.
For the nine months ended September 30, 2021, net cash provided by operating activities was $58.0 million compared to net cash used in operating activities of $24.0 million for the nine months ended September 30, 2020. Our operating activities included our net loss of $0.4 million and net loss of $59.3 million for the nine months ended September 30, 2021 and 2020, respectively, which were offset by non-cash adjustments of $36.8 million and $55.6 million, respectively. In the nine months ended September 30, 2021, cash provided by operating activities increased by a net decrease in our working capital of $21.6 million. Net cash used in operating activities for the nine months ended September 30, 2020 was increased by a net increase in our working capital of $20.3 million. The net changes in working capital for both periods 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 to develop our internal use software in support of creating and enhancing our technology infrastructure, and
48

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 2020. 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 this 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 nine months ended September 30, 2021 and 2020, our investing activities used net cash of $675.6 million and provided net cash of $43.5 million, respectively. During the nine months ended September 30, 2021 and 2020, we used cash for purchases of property and equipment of $14.0 million and $4.2 million, respectively, and used cash for investments in our internally developed software of $8.5 million and $6.9 million, respectively. During the nine months ended September 30, 2021, we used net cash of $653.1 million to acquire SpotX and SpringServe. During the nine months ended September 30, 2020, we acquired $54.6 million cash in the Telaria Merger.
We believe that cash flows used in our investing activities will continue to increase as a result of investments associated with supporting our overall growth, primarily property and equipment, and internally developed software.
    Financing Activities
Our financing activities consisted of our Convertible Senior Notes offering, amounts borrowed against our Term Loan B Facility, and transactions related to our equity plans.
For the nine months ended September 30, 2021 and 2020, we received net cash of $688.9 million and we used net cash of $3.3 million, respectively, for financing activities. Cash inflows from financing activities for the nine months ended September 30, 2021 included an increase of $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 $8.7 million and $1.2 million cash proceeds from issuance of common stock from the employee stock purchase plan. These increases for the nine months ended September 30, 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 and $0.9 million repayment of Term Loan B. Cash outflows from financing activities for the nine months ended September 30, 2020 included payments of $7.8 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.
Off-Balance Sheet Arrangements
We do not have any relationships with other entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities that have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. We did not have any other off-balance sheet arrangements at September 30, 2021 other than the short-term operating leases and the indemnification agreements described below.
Contractual Obligations and Known Future Cash Requirements
As of September 30, 2021, our principal commitments consist of obligations under our Convertible Senior Notes, Term Loan B Facility, Revolving Credit Facility, leases for our various office facilities, operating lease agreements including data centers and cloud managed services that expire at various times through 2030, 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.
During the three and nine months ended September 30, 2021, we received rental income from subleases totaling $1.0 million and $3.3 million, respectively, and an $1.2 million and $2.5 million amount during the three and nine months ended September 30, 2020, respectively.
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 September 30, 2021.

(2) Interest payments are based on an assumed rate of 5.75%, which was the rate used as of September 30, 2021 for the associated Credit Agreement.
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 agreements in the normal course of business and purchase consideration that extend beyond a year.
There was no material change to the Company's unrecognized tax benefits in the three months ended September 30, 2021 and we do not expect to have any material changes to unrecognized tax benefits through December 31, 2021.
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 September 30, 2021.
Critical Accounting Policies and Estimates
Our condensed consolidated financial statements are prepared in accordance with GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. By their nature, estimates are subject to an inherent degree of uncertainty. Certain of our estimates and assumptions require increased judgment and carry a higher degree of variability and volatility that could result in material changes to our estimates in future periods. Our actual results could differ from these estimates.
We believe that the following assumptions and estimates have the greatest potential impact on our condensed 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 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. Besides the adoption of new accounting pronouncements, as included within "Note 1—Organization and Summary of Significant Accounting Policies" to the condensed consolidated financial statements in this report, 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 year ended December 31, 2020 included in our Annual Report on Form 10-K.

Item 3. 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 relatively 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 Term Loan B loans under the Credit Agreement which have 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 if the underlying base interest rate were to reset above the floor on such underlying interest rate.Similarly, the fair value of Term Loan B loans may fluctuate when the underlying base interest rate fluctuates below the floor. As of September 30, 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. 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 September 30, 2021, including intercompany balances, would result in a foreign currency loss of approximately $3.9 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.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Exchange Act. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives of ensuring that information we are required to disclose in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures, and is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. There is no assurance that our disclosure controls and procedures will operate effectively under all circumstances. Based upon the evaluation described above, our Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2021, our disclosure controls and procedures were effective at the reasonable assurance level.
Changes in Internal Control over Financial Reporting
There have been no changes in our internal control over financial reporting that occurred during the three months ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting, except as noted below.
We completed the SpotX Acquisition on April 30, 2021. See Note 7 of "Notes to Condensed Consolidated Financial Statements" for more information. We are currently integrating SpotX into our operations and internal control processes. As we complete this integration, we are analyzing, evaluating, and where necessary, making changes in control and procedures related to the SpotX business, which we expect to complete within one year after the date of acquisition. Pursuant to the SEC’s guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment in the year of acquisition, the scope of our assessment of the effectiveness of our internal controls over financial reporting at December 31, 2021 may exclude SpotX to the extent that they are not yet integrated into our internal controls environment.
Inherent Limitations on Effectiveness of Controls     
Management recognizes that a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud or error, if any, have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
We and our subsidiaries may from time to time be parties to legal or regulatory proceedings, lawsuits and other claims incident to our business activities and to our status as a public company. Such routine matters may include, among other things, assertions of contract breach or intellectual property infringement, claims for indemnity arising in the course of our business, regulatory investigations or enforcement proceedings, and claims by persons whose employment has been terminated. Such matters are subject to many uncertainties, and outcomes are not predictable with assurance. Consequently, we are unable to ascertain the ultimate aggregate amount of monetary liability, amounts which may be covered by insurance or recoverable from third parties, or the financial impact with respect to such matters as of September 30, 2021. However, based on our knowledge as of September 30, 2021, we believe that the final resolution of such matters pending at the time of this report, individually and in the aggregate, will not have a material adverse effect upon our condensed consolidated financial position, results of operations or cash flows.
Refer to Note 12—"Commitments and Contingencies" for additional information related to legal proceedings.

Item 1A. Risk Factors
Investing in our common stock involves a high degree of risk. We describe risks associated with our business below and in Part I, Item 1A: "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2020 and in Part II, Item 1A "Risk Factors" of our Quarterly Reports on Form 10-Q for the periods ended March 31, 2021 and June 30, 2021 (the "Risk Factors"). Each of the risks described in our Risk Factors may be relevant to decisions regarding an investment in or ownership of our stock. The occurrence of any such risks could have a significant adverse effect on our reputation, business, financial condition, revenue, results of operations, growth, or ability to accomplish our strategic objectives, and could cause the trading price of our common stock to decline. You should carefully consider such risks and the other information contained in this report, including our condensed consolidated financial statements and related notes and Management's Discussion and Analysis of Financial Condition and Results of Operations, before making investment decisions related to our common stock.
The following risk factors supplement the Risk Factors contained in our Annual Report on Form 10-K for the year ended December 31, 2020 and in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2021 and June 30, 2021. The following disclosures do not address all risks that may be important to you as a Magnite stockholder.
Except as set forth below, there are no additional material changes to the Risk Factors of which we are currently aware; but our Risk Factors cannot anticipate and fully address all possible risks of investing in our common stock, the risks of investing in our common stock may change over time, and additional risks and uncertainties that we are not aware of, or that we do not consider to be material, may emerge. Accordingly, you are advised to consider additional sources of information and exercise your own judgment in addition to the information we provide.

Sales of our common stock by the former owner of SpotX may have an adverse effect on the price of our common stock.
As part of the consideration for the SpotX Acquisition, we issued to the seller of SpotX 12,374,315 shares of our common stock. In accordance with the terms of a registration rights agreement entered into at the closing of the SpotX Acquisition, the holder of such shares previously elected to require the Company to file a registration statement in order to register such shares for resale by such holder. This request was subsequently withdrawn, but given that the contractual lockup period applicable to such shares has expired, the holder could sell some or all of such shares under available exemptions from registration under federal securities laws. Sales by the former owner of SpotX of its shares of our common stock, or the possibility of such sales, pursuant to an underwritten offering or otherwise, may have an adverse effect on the per share price of our common stock.

The elimination of LIBOR after June 2023 may affect our financial results.
On March 5, 2021, the United Kingdom Financial Conduct Authority, which regulates LIBOR, announced that all LIBOR tenors relevant to us will cease to be published or will no longer be representative after June 30, 2023. This means that any of our LIBOR-based borrowings that extend beyond June 30, 2023 will need to be converted to a replacement rate. In the U.S., the Alternative Reference Rates Committee, or ARRC, a committee of private sector entities with ex-officio official sector members convened by the Federal Reserve Board and the Federal Reserve Bank of New York, has recommended the Secured Overnight Financing Rate ("SOFR") plus a recommended spread adjustment as LIBOR's replacement. There are significant differences between LIBOR and SOFR, such as LIBOR being an unsecured lending rate while SOFR is a secured lending rate, and SOFR is an overnight rate while LIBOR reflects term rates at different maturities. If our LIBOR-based borrowings are converted to SOFR, the differences between LIBOR and SOFR, plus the recommended spread adjustment, could result in interest costs that are higher than if LIBOR remained available, which could have a material adverse effect on our operating results. Although SOFR is the ARRC's recommended replacement rate, it is also possible that lenders may instead choose alternative replacement rates that may differ from LIBOR in ways similar to SOFR or in other ways that would result in higher interest costs for us. It is not yet possible to predict the magnitude of LIBOR's end on our borrowing costs given the remaining uncertainty about which rates will replace LIBOR.

The recent COVID-19 pandemic and spread of COVID-19 has impacted and may have material adverse effects on our business, financial position, results of operations and/or cash flows.
Our business has been impacted and may be materially adversely impacted by the effects of the COVID-19 pandemic. In addition to the United States, we have personnel and operations in the United Kingdom, Canada, France, Australia, New Zealand, Germany, Italy, Japan, Singapore, and Brazil, and each of these countries has been affected by the pandemic and taken measures to try to contain it. These measures have impacted and may further impact our workforce and operations, and the operations of our sellers and buyers.
The COVID-19 pandemic has in the short-run and may over the longer term adversely affect the economies and financial markets of many countries. Adverse economic conditions and general uncertainty about economic recovery or growth, particularly in North America and Europe, where we conduct most of our business, has caused many advertisers to reduce their advertising budgets. For example, recent global supply chain disruptions have negatively impacted certain advertising verticals leading to reductions in advertising budgets. Our business depends on the overall demand for advertising and on the economic health of our
53

current and prospective sellers and buyers. As a result of advertisers reducing their overall advertising spending, our revenue and results of operations have been directly affected. Though our revenue trends improved and stabilized, there can be no assurance that these trends will continue.
In addition, the economic health of our current and prospective buyers impacts the collectability of our accounts receivable. Although our liquidity has not been significantly affected by the effects of COVID-19 to date, any prolonged downturn in economic conditions in the future may severely impact our liquidity as we may need additional time to collect from buyers, which may impact our ability to pay sellers.
The degree to which the COVID-19 pandemic and responses thereto impacts our results 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. Although the full magnitude of the impact of the COVID-19 pandemic on our business and operations remains uncertain, the spread of COVID-19 and the imposition of related public health measures and travel and business restrictions has and is expected to continue to adversely impact our forecasted business, financial condition, operating results and cash flows.
Additional or unforeseen effects from the COVID-19 pandemic, including indirect effects such as supply chain disruptions, inflation and labor shortages, and the resulting economic distress could implicate or amplify many of the other risks discussed under the heading "Risk Factors" in our periodic reports.


Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
(a) Recent Sales of Unregistered Securities
    None (except as previously disclosed).
(b) Use of Proceeds
    Not Applicable.
(c) Purchases of Equity Securities by the Company and Affiliated Purchasers
    We currently have no publicly announced repurchase plan or program.
    Upon vesting of most restricted stock units or stock awards, we are required to deposit statutory employee withholding taxes on behalf of the holders of the vested awards. As reimbursement for these tax deposits, we have the option to withhold from shares otherwise issuable upon vesting a portion of those shares with a fair market value equal to the amount of the deposits we paid. Withholding of shares in this manner is accounted for as a repurchase of common stock.
