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.

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

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

  Table of Contents
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.

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.

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."

Revenue ex-TAC:
Revenue ex-TAC is revenue excluding traffic acquisition cost ("TAC"). Traffic
acquisition cost, a component of Cost of revenue, represents what we must pay
sellers for the sale of advertising inventory through our platform for revenue
reported on a gross basis. In calculating Revenue ex-TAC, we add back the cost
of revenue, excluding TAC, to gross profit, the most comparable GAAP
measurement. Revenue ex-TAC is a non-GAAP financial measure. 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:

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

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
--------------------------------------------------------------------------------
  Table of Contents
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.
