We caution you that the foregoing list may not contain all of the forward-looking statements made in this Annual
Report on Form 10-K.
You should not rely upon forward-looking statements as predictions of future events. We have based the forward-
looking statements contained in this Annual Report on Form 10-K primarily on our current expectations and projections
about future events and trends that we believe may affect our business, financial condition, operating results, cash flows
or prospects. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties
and other factors described in the section titled “Risk Factors” and elsewhere in this Annual Report on Form 10-K.
Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from
time to time and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-
looking statements contained in this Annual Report on Form 10-K. We cannot assure you that the results, events and
circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events or
circumstances could differ materially from those described in the forward-looking statements.
The forward-looking statements made in this Annual Report on Form 10-K relate only to events as of the date on
which the statements are made. We undertake no obligation to update any forward-looking statements made in this
Annual Report on Form 10-K to reflect events or circumstances after the date of this Annual Report on Form 10-K or to
reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve
the plans, intentions or expectations disclosed in our forward-looking statements and you should not place undue reliance
on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future
acquisitions, mergers, dispositions, joint ventures or investments we may make.

NOTE REGARDING KEY METRICS
We review a number of metrics, including monetizable daily active usage or users, or mDAUs, monthly active usage
or users, or MAUs, changes in ad engagements and changes in cost per ad engagement, to evaluate our business,
measure our performance, identify trends affecting our business, formulate business plans and make strategic decisions.
See the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key
Metrics” for a discussion of how we calculate mDAUs, MAUs, changes in ad engagements and changes in cost per ad
engagement.
We define monetizable daily active usage or users (mDAU) as Twitter users who logged in and accessed Twitter on
any given day through Twitter.com or Twitter applications that are able to show ads. Our definition and calculation of
mDAU is the same as that of the DAU data presented since the first quarter of 2016. The calculation of mDAU is not
based on any standardized industry methodology and is not necessarily calculated in the same manner or comparable to
similarly-titled measures presented by other companies. Average mDAU for a period represents the number of mDAU on
each day of such period divided by the number of days for such period. Changes in mDAU are a measure of changes in
the size of our daily logged in active user base. To calculate the year-over-year change in mDAU, we subtract the average
mDAU for the three months ended in the previous year from the average mDAU for the same three months ended in the
current year and divide the result by the average mDAU in the previous year.
We define monthly active usage or users (MAU) as Twitter users who logged in or were otherwise authenticated and
accessed Twitter through our website, mobile website, desktop or mobile applications, SMS or registered third-party
applications or websites in the 30-day period ending on the date of measurement. Average MAU for a period represent
the average of the MAU at the end of each month during the period. We believe that mDAU, and its related growth, are
the best ways to measure our success against our objectives and to show the size of our audience and engagement
going forward, so we will discontinue disclosing MAU after the first quarter of 2019.
Certain metrics also include users that access Twitter through applications that automatically contact our servers for
regular updates with no discernible user-initiated action involved, which we refer to as third-party auto-polling MAU. This
activity causes our system to count MAUs associated with such applications as active users on the day or days such
contact occurs. As of December 31, 2018, fewer than 8.5% of MAUs may have been third-party auto-polling MAU. Third-
party auto-polling does not apply to mDAU as mDAU does not include users accessing Twitter through third-party
applications.
5
The numbers of active users presented in this Annual Report on Form 10-K are based on internal company data.
While these numbers are based on what we believe to be reasonable estimates for the applicable period of measurement,
there are inherent challenges in measuring usage and user engagement across our large user base around the world.
Furthermore, our metrics may be impacted by our information quality efforts, which are our overall efforts to reduce
malicious activity on the service, inclusive of spam, malicious automation, and fake accounts. For example, there are a
number of false or spam accounts in existence on our platform. We have performed an internal review of a sample of
accounts and estimate that the average of false or spam accounts during the fourth quarter of 2018 represented fewer
than 5% of our MAU and mDAU during the quarter. The false or spam accounts for a period represents the average of
false or spam accounts in the samples during each monthly analysis period during the quarter. In making this
determination, we applied significant judgment, so our estimation of false or spam accounts may not accurately represent
the actual number of such accounts, and the actual number of false or spam accounts could be higher than we have
estimated. We are continually seeking to improve our ability to estimate the total number of spam accounts and eliminate
them from the calculation of our active users, and have made improvements in our spam detection capabilities that have
resulted in the suspension of a large number of spam, malicious automation and fake accounts. We intend to continue to
make such improvements. After we determine an account is spam, malicious automation or fake, we stop counting it in
our MAU, mDAU, or related metrics. Additionally, we rely on third-party SMS aggregators and mobile carriers to deliver
SMS messages to certain of our users when we send our SMS messages to such accounts. If, however, we are notified
of material deliverability issues because of, for example, infrastructure issues at the service-provider level or
governmental restrictions based on content, we do not include the affected users in MAUs. We also treat multiple
accounts held by a single person or organization as multiple users for purposes of calculating our active users because
we permit people and organizations to have more than one account. Additionally, some accounts used by organizations
are used by many people within the organization. As such, the calculations of our active users may not accurately reflect
the actual number of people or organizations using our platform.
In addition, our data regarding user geographic location for purposes of reporting the geographic location of our
MAU and mDAU is based on the IP address or phone number associated with the account when a user initially registered
the account on Twitter. The IP address or phone number may not always accurately reflect a user’s actual location at the
time such user engaged with our platform. For example, a mobile user may appear to be accessing Twitter from the
location of the proxy server that the user connects to rather than from a user’s actual location.
We regularly review and may adjust our processes for calculating our internal metrics to improve their accuracy. Our
measures of user growth and user engagement may differ from estimates published by third parties or from similarly-titled
metrics of our competitors due to differences in methodology.
Our total audience metrics are based on both internal metrics and data from Google Analytics, which measures
logged-out visitors to our properties.

Item 1. BUSINESS
Overview
PART I
Twitter is what’s happening in the world and what people are talking about right now. From breaking news and
entertainment, to sports, politics, and everyday interests, Twitter shows every side of the story. On Twitter you can join the
open conversation and watch highlights, clips, or live-streaming events. Twitter is available in more than 40 languages
around the world. The service can be accessed via twitter.com, an array of mobile devices via Twitter owned and
operated mobile applications (e.g. Twitter for iPhone and Twitter for Android), and SMS.
In 2018, we took important steps to increase the collective health, openness, and civility of the public conversation
on Twitter, helping people see high-quality information, strengthening our sign-up and account verification processes, and
preventing the abuse of Twitter data. Specific actions we took in 2018 included: strengthening account security, updating
our rules to more clearly address specific types of hateful conduct, taking new behavior-based signals into account when
presenting and organizing Tweets, making it easier to see when a Tweet was removed for breaking our rules, and
expanding our team through increased hiring and acquisition. In 2018, our machine learning efforts continued to improve,
making it harder for malicious accounts to manipulate our service through multiple accounts and evading suspension,
resulting in the suspension of millions of spammy and suspicious accounts. We also continued our work to make it easier
to follow and discuss events as they are unfolding with expanded coverage of sports, entertainment, news, elections, and
other topics and events.
Products and Services for Users
Our primary product, Twitter, is a global platform for public self-expression and conversation in real time. Twitter
allows people to consume, create, distribute and discover content and has democratized content creation and distribution.
Periscope is a mobile application that lets anyone broadcast and watch video live with others. Periscope broadcasts can
also be viewed through Twitter and on desktop or mobile web browsers. We continue to implement live broadcasts across
Twitter, including trends and moments, to help people discover what’s happening live.
The reach of Twitter content is not limited to our logged-in users on the Twitter platform, but rather extends to a
much larger global audience. The public nature of the Twitter platform allows us and others to extend the reach of Twitter
content beyond our properties. Over 1 million media outlets and our platform partners distribute Tweets beyond our
properties to complement their content by making it more timely, relevant and comprehensive. These outlets and partners
also add value to our user experience by contributing content to our platform. Many of the world’s most trusted media
outlets and publishers regularly use Twitter as a platform for content distribution.
Products and Services for Advertisers
Our Promoted Products enable our advertisers to launch products and services and promote their brands, amplify
their visibility and reach, and connect with our audience, while extending the conversation around their advertising
campaigns. We enable our advertisers to target an audience based on a variety of factors, including a user’s interest
graph. The interest graph maps, among other things, interests based on users followed and actions taken on our platform,
such as Tweets created and engagement with Tweets. We believe a user’s interest graph produces a clear and real-time
signal of a user’s interests, greatly enhancing the relevance of the ads we can display for users and enhancing our
targeting capabilities for advertisers. Our Promoted Products are incorporated into our platform as native advertising and
are designed to be as compelling and useful to our users as organic content on our platform.
7
Currently, our Promoted Products consist of:
•
•
•
Promoted Tweets. Promoted Tweets appear within a user’s timeline, search results or profile pages just like an
ordinary Tweet regardless of device. Promoted Tweets often include images and videos, such as App Cards
and Website Cards. Using our proprietary algorithm and understanding of each user’s interest graph, we can
deliver Promoted Tweets that are intended to be relevant to a particular user. Our goal is to enable advertisers
to create and optimize successful marketing campaigns — and pay either on impressions delivered or pay only
for the user actions that are aligned with their marketing objectives. As a result, we have added product
features to Promoted Tweets based on advertiser objectives, which may include Tweet engagements (e.g.,
retweets, replies and likes), website clicks or conversions, mobile application installs or engagements,
obtaining new followers, or video views.
Promoted Accounts. Promoted Accounts appear in the same format and place as accounts suggested by our
Who to Follow recommendation engine, or in some cases, in Tweets in a user’s timeline. Promoted Accounts
provide a way for our advertisers to grow a community of users who are interested in their business, products
or services.
Promoted Trends. Promoted Trends appear at the top of the list of trending topics or timeline for an entire day
in a particular country or on a global basis. When a user clicks on a Promoted Trend, search results for that
trend are shown in a timeline and a Promoted Tweet created by our advertisers is displayed to the user at the
top of those search results. We feature one Promoted Trend per day per geography.
Advertisers can also run short video ads, such as In-Stream video ads, either before or around premium video
content, such as during live premium video content from publishing partners or clips from a variety of interest categories
such as news, sports and entertainment. Our technology dynamically inserts those advertisers' ads into the relevant
videos and delivers the ads to the audience targeted by those advertisers. We may pay content partners a portion of our
advertising revenue for the right to use and distribute their content on our platform. In addition, In-Stream Video
Sponsorships allow advertisers to build brand association by sponsoring premium video content from a single publishing
partner, including live video, video clips, and other storytelling formats like Sponsored Moments.
We continue to focus our investment in features that differentiate Twitter and capitalize on our value proposition for
advertisers, including video and more organic ad formats such as Video Website Card.
Our technology platform and information database enable us to provide targeting capabilities based on audience
attributes like geography, interests, keyword, television conversation, content, and events that make it possible for
advertisers to promote their brands, products and services, amplify their visibility and reach, and complement and extend
the conversation around their advertising campaigns.
Our platform also enables customers to advertise across the mobile ecosystem, both on Twitter’s owned and
operated properties as well as off Twitter on third-party publishers’ websites, applications and other offerings, across the
full user lifecycle — from acquiring new users to engaging existing users. We enable advertisers to extend their reach
beyond Twitter through:
•
•
MoPub, our mobile-focused advertising exchange, which combines ad serving, ad network mediation and a
real-time bidding exchange into one comprehensive monetization platform.
Twitter Audience Platform, an advertising offering that enables advertisers to extend their advertising
campaigns with Twitter Promoted Products to audiences off Twitter while retaining access to Twitter’s
measurement, targeting and creative tools.
Content Partnerships
Video is an important way to stay informed on Twitter, enabling users and content owners to better share
experiences, engage in events, and converse with broader audiences. We continue to increase reach and engagement
for content owners around the world through live-streaming, highlight video clips, and video-on-demand agreements
signed to complement the user generated and licensed live and on-demand video content already available on Twitter
across a number of verticals including sports, news, and entertainment.
8
Products for Developers and Data Partners
We provide a set of tools, public APIs and embeddable widgets that developers can use to contribute their content to
our platform, syndicate and distribute Twitter content across their properties and enhance their websites and applications
with Twitter content. Websites and applications integrating with Twitter add value to our user experience. Many
applications have been registered by developers to enable them to integrate with our platform, and leverage Twitter
content to enhance and extend their applications in new and creative ways. The goal of our platform product development
is to make it easy for developers to integrate seamlessly with Twitter, while keeping this process safer and more secure
for Twitter users.
We also offer subscription access to our public data feed for partners who wish to access data beyond our public
API, which offers a limited amount of our public data for free. Our enterprise data products and services offer more
sophisticated data sets and better data enrichments to allow developers and businesses to utilize our public content to
derive business insights and build products using the unique content that is shared on Twitter. We have grown our data
licensing revenue with a more customer-centric approach to channels, markets, products, and pricing. We believe this
approach positions both Twitter and our key channel partners for greater growth and monetization, and we are investing in
deeper partnerships with a few select solution providers to help businesses and organizations realize greater value from
our data and platform.
Competition
Our business is characterized by rapid technological change, frequent product innovation and continuously evolving
user, advertiser, content partner, platform partner and developer preferences and expectations. We face significant
competition in every aspect of our business, including from companies that provide tools to facilitate communications and
the sharing of information, companies that enable marketers to display advertising, and other online ad networks,
exchanges and platforms. We also compete to attract, engage, and retain people who use our products, to attract and
retain marketers, and to attract and retain developers to build compelling mobile and web applications that integrate with
our products. We have seen escalating competition for digital ad spending and expect this trend to continue. We also
compete to attract and retain employees, especially software engineers, designers, and product managers.
We compete with the following companies for users’ attention and for advertisers’ budgets:
•
•
•
•
Companies that offer products that enable everyone to create and share ideas, videos, and other content and
information. These offerings include, for example, Facebook (including Instagram and WhatsApp) and
Alphabet (including Google and YouTube), Microsoft (including LinkedIn), Snap, TikTok, and Verizon Media
Group, as well as largely regional social media and messaging companies that have strong positions in
particular countries (including WeChat, Kakao, and Line). Although we often seek differentiated content from
other licensors, we face competition for live premium video content rights from other digital distributors and
traditional television providers, which may limit our ability to secure such content on economic and other terms
that are acceptable to us in the future.
Companies that offer advertising inventory and opportunities to advertisers.
Companies that develop applications, particularly mobile applications, that create, syndicate and distribute
content across internet properties.
Traditional, online, and mobile businesses that enable users to consume content or marketers to reach their
audiences and/or develop tools and systems for managing and optimizing advertising campaigns.
As we introduce new products, as our existing products evolve, or as other companies introduce new products and
services, we may become subject to additional competition.
Our industry is evolving rapidly and is becoming increasingly competitive. See the sections titled “Risk Factors—If
we are unable to compete effectively for users and advertiser spend, our business and operating results could be harmed”
and “Risk Factors—We depend on highly skilled personnel to grow and operate our business, and if we are unable to hire,
retain and motivate our personnel, we may not be able to grow effectively.”
9
Technology, Research and Development
Twitter is composed of a set of core, scalable and distributed services that are built from proprietary and open
source technologies. These systems are capable of delivering billions of messages, including images and video, to
hundreds of millions of people a day in an efficient and reliable way. We continue to invest in our existing products and
services as well as develop new products and services through research and product development. We also continue to
invest in protecting the safety, security and integrity of our platform by investing in both people and technology, including
machine learning.
Sales and Marketing
We have a global sales force and sales support staff that is focused on attracting and retaining advertisers while
certain advertisers use our self-serve advertising platform to launch and manage their advertising campaigns. Our sales
force and sales support staff assist advertisers throughout the advertising campaign cycle, from pre-purchase decision
making to real-time optimizations as they utilize our campaign management tools, and to post-campaign analytics reports
to assess the effectiveness of their advertising campaigns.
Since our inception, our user base has grown primarily organically, complemented with targeted campaigns to drive
new user acquisition. In 2018, we set out to clearly define who we are and express the uniqueness and power of our
brand through marketing campaigns to drive awareness of Twitter’s unique positioning. We also solidified our value
proposition for advertisers with our “Start With Them” campaign, which highlights that Twitter connects advertisers with
the most valuable audiences when they are most receptive.
Intellectual Property
We seek to protect our intellectual property rights by relying on federal, state and common law rights in the United
States and other countries, as well as contractual restrictions. We generally enter into confidentiality and invention
assignment agreements with our employees and contractors, and confidentiality agreements with other third parties, in
order to limit access to, and disclosure and use of, our confidential information and proprietary technology. In addition to
these contractual arrangements, we also rely on a combination of trademarks, trade dress, domain names, copyrights,
trade secrets and patents to help protect our brand and our other intellectual property.
In May 2013, we implemented our Innovator’s Patent Agreement, or IPA, which we enter into with our employees
and consultants, including our founders. The IPA which applies to our current and future patents, allows us to assert our
patents defensively. The IPA also allows us to assert our patents offensively with the permission of the inventors of the
applicable patent. The IPA can limit our ability to prevent infringement of our patents. See the section titled “Risk Factors—
Our intellectual property rights are valuable, and any inability to protect them could reduce the value of our products,
services and brand” for a further discussion of the IPA.
Government Regulation
We are subject to a number of U.S. federal and state and foreign laws and regulations that involve matters central to
our business. These laws and regulations may involve privacy, rights of publicity, data protection, content regulation,
intellectual property, competition, protection of minors, consumer protection, taxation or other subjects. Many of these
laws and regulations are still evolving and being tested in courts and could be interpreted in ways that could harm our
business. In addition, the application and interpretation of these laws and regulations often are uncertain, particularly in
the new and rapidly evolving industry in which we operate.
We are also subject to federal, state and foreign laws regarding privacy and the protection of user data. Foreign data
protection, privacy, consumer protection, content regulation and other laws and regulations are often more restrictive than
those in the United States. For example, the General Data Protection Regulation, or the GDPR, which was effective from
May 2018. The GDPR also includes more stringent operational requirements for entities processing personal information
and significant penalties for non-compliance. There are also a number of legislative proposals pending before the U.S.
Congress, various state legislative bodies and foreign governments concerning content regulation and data protection that
could affect us, including the California Consumer Privacy Act.
10
In March 2011, to resolve an investigation into various incidents, we entered into a settlement agreement with the
Federal Trade Commission, or FTC, that, among other things, requires us to establish an information security program
designed to protect non-public consumer information and also requires that we obtain biennial independent security
assessments. The FTC investigation was the result of two separate incidents in which unauthorized intruders obtained
administrative passwords of certain Twitter employees. In one of the incidents, the intruder accessed the employee’s
administrative capabilities to fraudulently reset various user passwords and post unauthorized Tweets. The obligations
under the settlement agreement remain in effect until the later of March 2, 2031, or the date 20 years after the date, if any,
on which the U.S. government or the FTC files a complaint in federal court alleging any violation of the order. Violation of
existing or future regulatory orders, settlements, or consent decrees could subject us to substantial monetary fines and
other penalties that could negatively affect our financial condition and results of operations.
Twitter users may be restricted from accessing Twitter from certain countries, and other countries have intermittently
restricted access to Twitter. For example, Twitter is not directly accessible in China and has been blocked in the past in
Turkey. It is possible that other governments may seek to restrict access to or block our website or mobile applications,
censor content available through our products or impose other restrictions that may affect the accessibility or usability of
Twitter for an extended period of time or indefinitely. For instance, some countries have enacted laws that allow websites
to be blocked for hosting certain types of content.
For additional information, see the section titled “Risk Factors—Our business is subject to complex and evolving
U.S. and foreign laws and regulations. These laws and regulations are subject to change and uncertain interpretation, and
could result in claims, changes to our business practices, monetary penalties, increased cost of operations or declines in
user growth, user engagement or ad engagement, or otherwise harm our business.”
Seasonality
Advertising spending is traditionally strongest in the fourth quarter of each year. Historically, this seasonality in
advertising spending has affected our quarterly results, with higher sequential advertising revenue growth from the third
quarter to the fourth quarter compared to sequential advertising revenue from the fourth quarter to the subsequent first
quarter.
Backlog
As of December 31, 2018, our backlog primarily consists of long-term data licensing contracts. We generate the
substantial majority of our revenue from our advertising services. As such, we do not believe that our backlog, as of any
particular date, is necessarily indicative of actual revenue for any future period. Refer to Note 3 of the Notes to
Consolidated Financial Statements under Part II, Item 8 of this Annual Report on Form 10-K regarding the amount of
remaining performance obligations, which represents the significant majority of our contracted backlog.
Employees
As of December 31, 2018, we had 3,920 full-time employees.
Corporate Information
We were incorporated in Delaware in April 2007. Our principal executive offices are located at 1355 Market Street,

Item 1A. RISK FACTORS
Investing in our common stock involves a high degree of risk. You should carefully consider the risks and
uncertainties described below, together with all of the other information in this Annual Report on Form 10-K, including the
section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our
consolidated financial statements and related notes, before making a decision to invest in our common stock. The risks

financial condition, operating results, cash flows and prospects could be materially and adversely affected. In that event,
the market price of our common stock could decline, and you could lose part or all of your investment.
Risks Related to Our Business and Our Industry
If we fail to increase our mDAUs, ad engagement or other general engagement on our platform, our revenue,
business and operating results may be harmed.
The size of our mDAUs and those daily users’ level of engagement with advertising are critical to our success.
mDAUs for the three months ended December 31, 2018 were 126 million, an increase of 9% year-over-year. Our long-
term financial performance will continue to be significantly determined by our success in increasing the growth rate of our
mDAUs as well as the number of ad engagements. Our mDAU growth rate has fluctuated over time, and it may slow or
decline. To the extent our mDAU growth rate slows or the absolute number of mDAU declines, our revenue growth will
become dependent on our ability to increase levels of user engagement on Twitter and increase revenue growth from
third-party publishers’ websites and applications, data licensing and other offerings. To the extent our mDAU growth rate
slows, our success will become increasingly dependent on our ability to increase levels of ad engagement on Twitter. We
generate a substantial majority of our revenue based upon engagement by our users with the ads that we display. If
people do not perceive our products and services to be useful, reliable and trustworthy, we may not be able to attract
users or increase the frequency of their engagement with our platform and the ads that we display. A number of factors
could potentially negatively affect user growth and engagement, including if:
•
•
•
•
users, including influential users, such as world leaders, government officials, celebrities, athletes, journalists,
sports teams, media outlets and brands or certain age demographics, engage with other products, services or
activities as an alternative to ours;
we are unable to convince potential or new users of the value and usefulness of our products and services;
there is a decrease in the perceived quantity, quality, usefulness or relevance of the content generated by our
users or content partners;
there could also be a perception that actions we take to better foster a healthy conversation or to improve
relevancy on the platform negatively impact the content or ranking of content posted by certain users;
12
•
•
•
•
•
•
•
•
•
•
our content partners terminate their relationships with us or do not renew their agreements on economic or
other terms that are favorable to us;
there are user concerns related to privacy and communication, safety, security, spam, manipulation or other
hostile or inappropriate usage or other factors, or our health efforts result in the removal of certain accounts;
we fail to introduce new and improved products or services or if we introduce new or improved products or
services that are not favorably received or that negatively affect user engagement;
technical or other problems prevent us from delivering our products or services in a rapid and reliable manner
or otherwise affect the user experience, including issues with connecting to the Internet;
users have difficulty installing, updating, or otherwise accessing our products or services on mobile devices as
a result of actions by us or third parties that we rely on to distribute our products and deliver our services;
we are unable to manage and prioritize information to ensure users are presented with content that is
interesting, useful and relevant to them;
users believe that their experience is diminished as a result of the decisions we make with respect to the
frequency, format, relevance and prominence of ads or other content that we display;
changes in our products or services that are mandated by, or that we elect to make to address, laws (such as
the General Data Protection Regulation, or the GDPR) or legislation, inquiries from legislative bodies,
regulatory authorities or litigation (including settlements or consent decrees) adversely affect our products or
users;
we fail to provide adequate customer service to users; or
we do not maintain our brand image or our reputation is damaged.
We believe that meaningful improvement in audience growth rate and engagement is dependent on improving our
product and feature offerings to demonstrate our value proposition to a larger audience. If we are unable to increase our
user base, user growth rate or user engagement, or if these metrics decline, our products and services could be less
attractive to potential or new users, as well as to advertisers, content partners and platform partners, which would have a
material and adverse impact on our business, financial condition and operating results.
If the people who use our service or our content partners do not continue to contribute content or such content
is not viewed as unique or engaging by other users, we may experience a decline in users accessing our
products and services and their engagement, which could result in the loss of content partners, advertisers,
platform partners, and revenue.
Our success depends on our ability to provide users of our products and services with unique and engaging content,
which in turn depends on the content contributed by our users. We believe that one of our competitive advantages is the
quality, quantity and real-time nature of the content on Twitter, and that access to unique or real-time content is one of the
main reasons users visit Twitter. We seek to foster a broad and engaged user community, and we encourage world
leaders, government officials, celebrities, athletes, journalists, sports teams, media outlets and brands to use our products
and services to express their views to broad audiences. We also encourage media outlets to use our products and
services to distribute their content. In addition, we license our premium live streaming video content from a variety of
content providers. If these content providers are no longer willing or able to license us content upon economic and other
terms that are acceptable to us, our ability to stream such content will be adversely affected and/or our costs could
increase. If users, including influential users, do not continue to contribute content or content providers do not license
content to Twitter, and we are unable to provide users with unique, engaging and timely content, our user base and
engagement may decline. Additionally, if we are not able to address user concerns regarding the safety and security of
our products and services or if we are unable to successfully prevent or mitigate spammy, abusive or other disruptive or
detracting behavior on our platform, the size of our engaged user base may decline. We rely on the sale of advertising
services for the substantial majority of our revenue. We believe advertisers come to Twitter because we have one of the
most valuable audiences when they are most receptive, and we generate a high return on investment against their
campaign objectives whether they are launching a new product or connecting with what's happening on Twitter. However,
a decline in the number of users, user growth rate, or user engagement, including as a result of the loss of world leaders,
government officials, celebrities, athletes, journalists, sports teams, media outlets and brands who generate content on
Twitter, may deter advertisers from using our products or services or cause current advertisers to reduce their spending
with us or cease doing business with us, which would harm our business and operating results.
13
We generate the substantial majority of our revenue from advertising. The loss of advertising revenue could
harm our business.
The substantial majority of our revenue is currently generated from third parties advertising on Twitter. We
generated approximately 86% of our revenue from advertising in each of the years ended December 31, 2017 and 2018.
We generate substantially all of our advertising revenue through the sale of our Promoted Products: Promoted Tweets,
Promoted Accounts and Promoted Trends. As is common in our industry, our advertisers do not have long-term
advertising commitments with us. In addition, many of our advertisers purchase our advertising services through one of
several large advertising agency holding companies. To sustain or increase our revenue, we must add new advertisers
and encourage existing advertisers to maintain or increase the amount of advertising inventory purchased through our
platform and adopt new features and functionalities that we add to our platform. However, advertising agencies and
potential new advertisers may view our Promoted Products or any new products or services we offer as experimental and
unproven, and we may need to devote additional time and resources to educate them about our products and services.
Advertisers also may choose to reach users through our free products and services, instead of our Promoted Products.
Advertisers will not continue to do business with us, or they will reduce the prices they are willing to pay to advertise with
us, if we do not deliver ads in an effective manner, or if they do not believe that their investment in advertising with us will
generate a competitive return on investment relative to alternatives, including online, mobile and traditional advertising
platforms. In addition, competition for advertising is becoming increasingly more intense and our advertising revenue
could be further impacted by escalating competition for digital ad spending as well as the re-evaluation of our revenue
product feature portfolio, which could result in the de-emphasis of certain product features. Our revenue growth is
primarily driven by increases in the number of our mDAUs, increases in ad pricing or number of ads shown driven by
strong advertiser demand, increases in our clickthrough rate, as well as other factors. To date, our available advertising
inventory has been greater than demand. Our future revenue growth, however, may be limited by available advertising
inventory for specific ad types on certain days if we do not increase our mDAU or monetize our larger global audience.
Our advertising revenue also could be adversely affected by a number of other factors, including:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
decreases in user engagement with the ads on our platform and those that we serve off of our platform;
decreases in the size of our mDAUs or the growth rate of mDAUs;
if we are unable to demonstrate the value of our Promoted Products to advertisers and advertising agencies or
if we are unable to measure the value of our Promoted Products in a manner which advertisers and advertising
agencies find useful or reliable;
if we are perceived as not safe for brand advertisers;
if we are unable to demonstrate the value of, or attract video and video advertisements to, our platform;
decreases in the perceived quantity, quality, usefulness or relevance of our users or the content generated by
our users or content partners;
if our Promoted Products are not cost effective or not valued by certain types of advertisers or if we are unable
to develop cost effective or valuable advertising services for different types of advertisers;
if we are unable to convince advertisers and brands to invest resources in learning to use our products and
services and maintaining a brand presence on Twitter;
our advertisers’ ability to optimize their campaigns or effectively and reliably measure the results of their
campaigns;
product or service changes we may make that change the frequency or relative prominence of ads displayed
on Twitter or that detrimentally impact revenue in the near term with the goal of achieving long -term benefits;
our inability to increase advertiser demand and spend from new and existing advertisers as well as advertising
inventory;
our inability to increase the relevance of ads shown to users;
our inability to help advertisers effectively target ads, including as a result of the fact that we do not collect
extensive personal information from our users and that we do not have real-time geographic information for all
of our users particularly for ads served through our app mobile-focused advertising exchange;
decreases in the cost per ad engagement;
failure to effectively monetize our growing international user base, our logged-out audience or our syndicated
audience;
14
•
•
•
•
•
•
•
•
•
•
•
loss of advertising market share to our competitors;
the degree to which users access Twitter content through applications that do not contain our ads;
any arrangements or other partnerships with third parties to share our revenue;
if our new advertising strategies do not gain traction;
the impact of new technologies that could block or obscure the display of our ads;
adverse legal developments relating to advertising or measurement tools related to our metrics or the
effectiveness of advertising, including legislative and regulatory developments, such as GDPR and other
privacy regulations, and developments in litigation;
our inability to create new products, product features and services that sustain or increase the value of our
advertising services to both our advertisers and our users;
changes to our products or development of new products or product features that decrease users’ ad
engagements or limit the types of user interactions that we count as ad engagements;
the impact of fraudulent clicks or spam on our Promoted Products and our users;
changes in the way our advertising is priced; and
the impact of macroeconomic conditions and conditions in the advertising industry in general.
The occurrence of any of these or other factors could result in a reduction in demand for our ads, which may reduce
the prices we receive for our ads, either of which would negatively affect our revenue and operating results.
If we are unable to compete effectively for users and advertiser spend, our business and operating results could
be harmed.
Competition for users of our products and services is intense. Although we have developed a global platform that we
believe is the best and fastest place to see what’s happening and what people are talking about all around the world, we
face strong competition in our business. We compete against many companies to attract and engage users every day,
including companies which have greater financial resources and substantially larger user bases, such as Facebook
(including Instagram and WhatsApp), Alphabet (including Google and YouTube), Microsoft (including LinkedIn), Snap,
TikTok, and Verizon Media Group, which offer a variety of Internet and mobile device-based products, services and
content. For example, Facebook operates a social networking site with significantly more users than Twitter and has been
introducing features similar to those of Twitter. In addition, Alphabet may use its strong position in one or more markets to
gain a competitive advantage over us in areas in which we operate, including by integrating competing features into
products or services they control. As a result, our competitors may draw users towards their products or services and
away from ours. This could decrease the growth or engagement of our user base, which, in turn, would negatively affect
our business. We also compete against largely regional social media and messaging companies that have strong
positions in particular countries such as WeChat, Kakao and Line.
We believe that our ability to compete effectively for users depends upon many factors both within and beyond our
control, including:
•
•
•
•
•
•
•
the popularity, usefulness, ease of use, performance and reliability of our products and services compared to
those of our competitors;
the amount, quality and timeliness of content generated by our users and content partners;
the timing and market acceptance of our products and services;
our ability, in and of itself, and in comparison to the ability of our competitors, to develop new products and
services and enhancements to existing products and services;
the frequency and relative prominence of the ads displayed by us or our competitors;
our ability to establish and maintain relationships with content partners;
our ability to develop a reliable, scalable, secure, high-performance technology infrastructure that can
efficiently handle increased usage globally;
15
•
•
•
•
•
•
changes mandated by, or that we elect to make to address, legislation, regulatory authorities or litigation,
including settlements, consent decrees and the GDPR, some of which may have a disproportionate effect on
us;
the application of antitrust laws both in the United States and internationally;
the continued adoption of our products and services internationally;
our ability to establish and maintain relationships with platform partners that integrate with our platform;
acquisitions or consolidation within our industry, which may result in more formidable competitors; and
our reputation and brand strength relative to our competitors.
We also face significant competition for advertiser spend. The substantial majority of our revenue is currently
generated through third parties advertising on Twitter, and we compete against online and mobile businesses, including
those referenced above, and traditional media outlets, such as television, radio and print, for advertising budgets. In
addition, many advertisers, particularly branded advertisers, use marketing mix analyses to determine how to allocate
their advertising budgets on an annual or bi-annual basis. Accordingly, if we fail to demonstrate to such advertisers during
the appropriate time period that we provide a better return on investment than our competitors do, we may lose the
opportunity to secure, increase or sustain our share of the advertising budget allocated for a significant portion of the year
until the next budget cycle.
We also compete with advertising networks, exchanges, demand side platforms and other platforms, such as
Google AdSense, DoubleClick Ad Exchange, Nexage and Brightroll Ad Exchanges, Verizon Media Group, and Microsoft
Media Network, for marketing budgets and in the development of the tools and systems for managing and optimizing
advertising campaigns. In order to grow our revenue and improve our operating results, we must increase our share of
spending on advertising relative to our competitors, many of which are larger companies that offer more traditional and
widely accepted advertising products. In addition, some of our larger competitors have substantially broader product or
service offerings and leverage their relationships based on other products or services to gain additional share of
advertising budgets.
We believe that our ability to compete effectively for advertiser spend depends upon many factors both within and
beyond our control, including:
•
•
•
•
•
•
•
the size and composition of our user base relative to those of our competitors;
our ad targeting and measurement capabilities, and those of our competitors;
the timing and market acceptance of our advertising services, and those of our competitors;
our marketing and selling efforts, and those of our competitors;
the pricing of our advertising products and services relative to those of our competitors;
the actual or perceived return our advertisers receive from our advertising services, and those of our
competitors; and
our reputation and the strength of our brand relative to our competitors.
In recent years, there have been significant acquisitions and consolidation by and among our actual and potential
competitors. We anticipate this trend of consolidation will continue, which will present heightened competitive challenges
for our business. Acquisitions by our competitors may result in reduced functionality of our products and services. For
example, following Facebook’s acquisition of Instagram, Facebook disabled Instagram’s photo integration with Twitter
such that Instagram photos were no longer viewable within Tweets and users are instead re-directed to Instagram to view
Instagram photos through a link within a Tweet. As a result, our users may be less likely to click on links to Instagram
photos in Tweets, and Instagram users may be less likely to Tweet or remain active users of Twitter. Any similar
elimination of integration with Twitter in the future, whether by Facebook or others, may adversely impact our business
and operating results.
16
Consolidation may also enable our larger competitors to offer bundled or integrated products that feature
alternatives to our platform. Reduced functionality of our products and services, or our competitors’ ability to offer bundled
or integrated products that compete directly with us, may cause our users, user growth rate, and ad engagement to
decline and advertisers to reduce their spend with us.
If we are not able to compete effectively for users and advertiser spend our business and operating results would be
materially and adversely affected.
Our priority as a company is to improve the health of the public conversation on Twitter. Focusing our efforts on
this priority may negatively impact our business operations in the short term.
We believe that our long-term success depends on our ability to improve the health of the public conversation on
Twitter. We have made this our priority and have focused our efforts on improving the quality of that conversation,
including by devoting substantial internal resources to our strategy. These efforts include the reduction of abuse,
harassment, spam, manipulation and malicious automation on the platform, as well as a focus on improving information
quality and the health of conversation on Twitter. For example, we recently announced that we were removing certain
locked accounts from follower counts across profiles globally. While that specific change did not affect our previously-
disclosed MAU or DAU metrics, some of the health initiatives that we have implemented as part of our ongoing
commitment to a healthy public conversation have negatively impacted, and may in the future negatively impact, our
publicly reported metrics in a few ways. First, our health efforts include the removal of accounts pursuant to our terms and
services that are abusive, spammy, fake or malicious, and these accounts may be monthly active or daily active users, as
well as actions taken to detect and challenge potentially automated, spammy, or malicious accounts during the sign-up
process. For example, in the third and fourth quarters of 2018, year-over-year average mDAU growth was impacted by
ongoing health efforts, both due to how we resourced and prioritized our work and the impact from ongoing success
removing spammy and suspicious accounts. Second, we are also making active decisions to prioritize health related
initiatives over other near-term product improvements that may drive more usage of Twitter as a daily utility. These
decisions may not be consistent with the short-term expectations of our advertising customers or investors and may not
produce the long-term benefits that we expect, in which case our user growth and user engagement, our relationships
with advertisers and our business and operating results could be harmed.
Our operating results may fluctuate from quarter to quarter, which makes them difficult to predict.
Our quarterly operating results have fluctuated in the past and will fluctuate in the future. As a result, our past
quarterly operating results are not necessarily indicators of future performance. Our operating results in any given quarter
can be influenced by numerous factors, many of which we are unable to predict or are outside of our control, including:
•
•
•
•
•
•
•
•
•
•
•
•
our ability to provide something valuable to people on Twitter every day and grow our mDAU;
our ability to attract and retain advertisers, content partners and platform partners;
the occurrence of planned significant events, such as the World Cup, Super Bowl, Champions League Final,
World Series, Olympics and the Oscars, or unplanned significant events, such as natural disasters and political
revolutions;
the pricing of our products and services;
the development and introduction of new products or services, changes in features of existing products or
services or de-emphasis or termination of existing products, product features or services;
the impact of competitors or competitive products and services;
our ability to maintain or increase revenue;
our ability to maintain or improve gross margins and operating margins;
increases in research and development, marketing and sales and other operating expenses that we may incur
to grow and expand our operations and to remain competitive;
stock-based compensation expense;
costs related to the acquisition of businesses, talent, technologies or intellectual property, including potentially
significant amortization costs;
system failures resulting in the inaccessibility of our products and services;
17
•
•
•
•
•
•
•
•
breaches of security or privacy, and the costs associated with remediating any such breaches;
adverse litigation judgments, settlements or other litigation-related costs, and the fees associated with
investigating and defending claims;
changes in the legislative or regulatory environment, including with respect to security, tax, privacy, data
protection, or content, or enforcement by government regulators, including fines, orders or consent decrees;
changes in reserves or other non-cash credits or charges, such as releases of deferred tax asset valuation
allowances, impairment charges or purchase accounting adjustments;
changes in our expected estimated useful life of property and equipment and intangible assets;
fluctuations in currency exchange rates and changes in the proportion of our revenue and expenses
denominated in foreign currencies;
changes in U.S. generally accepted accounting principles; and
changes in global business or macroeconomic conditions.
Given our limited operating history and the rapidly evolving markets in which we compete, our historical operating
results may not be useful to you in predicting our future operating results. If our revenue growth rate slows, we expect that
the seasonality in our business may become more pronounced and may in the future cause our operating results to
fluctuate. For example, advertising spending is traditionally seasonally strong in the fourth quarter of each year and we
believe that this seasonality affects our quarterly results, which generally reflect higher sequential advertising revenue
growth from the third to fourth quarter compared to sequential advertising revenue growth from the fourth quarter to the
subsequent first quarter. In addition, global economic concerns continue to create uncertainty and unpredictability and add
risk to our future outlook. An economic downturn in any particular region in which we do business or globally could result
in reductions in advertising revenue, as our advertisers reduce their advertising budgets, and other adverse effects that
could harm our operating results.
We depend on highly skilled personnel to grow and operate our business, and have seen high levels of attrition.
If we are unable to hire, retain and motivate our personnel, we may not be able to grow effectively.
Our future success and strategy will depend upon our continued ability to identify, hire, develop, motivate and retain
highly skilled personnel, including senior management, engineers, designers and product managers. We depend on
contributions from our employees, and in particular our senior management team, to execute efficiently and effectively.
We do not have employment agreements other than offer letters with any member of our senior management or other key
employee, and we do not maintain key person life insurance for any employee. We also face significant competition for
employees, particularly in the San Francisco Bay Area (where our headquarters is located) and other key markets, for
engineers, designers and product managers from other Internet and high-growth companies, which include both publicly-
traded and privately-held companies. As a result, we may not be able to retain our existing employees or hire new
employees quickly enough to meet our needs. From time to time, we have also experienced high voluntary attrition, and in
those times, the resulting influx of new leaders and other employees has required us to expend time, attention and
resources to recruit and retain talent, restructure parts of our organization, and train and integrate new employees. In
addition, to attract highly and retain skilled personnel, we have had to offer, and believe we will need to continue to offer,
highly competitive compensation packages. We may need to invest significant amounts of cash and equity to attract and
retain new employees and we may not realize sufficient return on these investments. In addition, changes to U.S.
immigration and work authorization laws and regulations can be significantly affected by political forces and levels of
economic activity. Our business may be materially adversely affected if legislative or administrative changes to
immigration or visa laws and regulations impair our hiring processes or projects involving personnel who are not citizens
of the country where the work is to be performed. If we are not able to effectively attract and retain employees, we may
not be able to innovate or execute quickly on our strategy and our ability to achieve our strategic objectives will be
adversely impacted, and our business will be harmed.
We also believe that our culture and core values have been, and will continue to be, a key contributor to our success
and our ability to foster the innovation, creativity and teamwork we believe we need to support our operations. If we fail to
effectively manage our hiring needs and successfully integrate our new hires, our efficiency and ability to meet our
forecasts and our culture, employee morale, productivity and retention could suffer, and our business and operating
results could be adversely affected.
18
If we fail to monetize effectively in international markets, our revenue and our business will be harmed.
We may not be able to monetize our products and services internationally as effectively as in the United States as a
result of competition, advertiser demand, differences in the digital advertising market and digital advertising conventions,
as well as differences in the way that users in different countries access or utilize our products and services. For example,
a significant portion of users in emerging markets like India and Pakistan use feature phones and communicate via SMS
messaging, both of which have limited functionality and neither of which may be able to take full advantage of our
products and services offered on smartphone or our website or desktop applications. Users who access Twitter through
SMS messaging may monetize at lower rates than other users. Differences in the competitive landscape in international
markets may impact our ability to monetize our products and services. For example, in South Korea we face intense
competition from a messaging service offered by Kakao, which offers some of the same communication features as
Twitter. The existence of a well-established competitor in an international market may adversely affect our ability to
increase our user base, attract content partners, advertisers and platform partners and monetize our products in such
market. We may also experience differences in advertiser demand in international markets. For example, during times of
political upheaval, advertisers may choose not to advertise on Twitter. Certain international markets are also not as
familiar with digital advertising in general, or in new forms of digital advertising such as our Promoted Products. Further,
we face challenges in providing certain advertising products, features or analytics in certain international markets, such as
the European Union, due to government regulation. Our products and services may also be used differently abroad than
in the United States. In particular, in certain international markets where Internet access is not as rapid or reliable as in the
United States, users tend not to take advantage of certain features of our products and services, such as rich media
included in Tweets, video or live streaming video. The limitation of mobile devices of users in emerging and other markets
limits our ability to deliver certain features to those users and may limit the ability of advertisers to deliver compelling
advertisements to users in these markets, which may result in reduced ad engagements, which would adversely affect our
business and operating results.
If our revenue from our international operations, and particularly from our operations in the countries and regions
where we have focused our spending, does not exceed the expense of establishing and maintaining these operations, our
business and operating results will suffer. In addition, our user base may expand more rapidly in international regions
where we are less successful in monetizing our products and services. As our user base continues to expand
internationally, we will need to increase revenue from the activity generated by our international users in order to grow our
business. For example, average mDAUs outside the United States constituted 79% of our average mDAUs in the three
months ended December 31, 2018, but our international revenue, as determined based on the billing location of our
customers, was only 44% of our consolidated revenue in the three months ended December 31, 2018. Our inability to
successfully expand our business internationally could adversely affect our business, financial condition and operating
results.
19
User growth and engagement depend upon effective interoperation with operating systems, networks, devices,
web browsers and standards that we do not control.
We make our products and services available across a variety of operating systems and through websites. We are
dependent on the interoperability of our products and services with popular devices, desktop and mobile operating
systems and web browsers that we do not control, such as Mac OS, iOS, Windows, Android, Chrome and Firefox. Any
changes, bugs or technical issues in such systems, devices or web browsers or changes in our relationships with mobile
operating system partners or mobile carriers, or in their terms of service or policies that diminish the functionality of our
products and services, make it difficult for our users to access our content, limit our ability to target or measure the
effectiveness of ads, impose fees related to our products or services or give preferential treatment to competitive products
or services could adversely affect usage of our products and services. For example, many of our relationships with our
mobile carriers to deliver our SMS messages were originally negotiated as free or low-cost connections, but recently
some of the mobile carriers have been proposing fee increases for these arrangements, which may not be cost-effective
for us. This may, in turn, adversely affect the number of users who receive our SMS messages. Additionally, some of our
mobile carriers have experienced infrastructure issues due to natural disasters, which have caused deliverability errors or
poor quality communications with our products. Any such errors, regardless of whether caused by our infrastructure or
that of the service provider, may result in the loss of our existing users or may make it difficult to attract new users.
Further, if the number of platforms for which we develop our product expands, it will result in an increase in our operating
expenses. In order to deliver high quality products and services, it is important that our products and services work well
with a range of operating systems, networks, devices, web browsers and standards that we do not control. In addition,
because a majority of our users access our products and services through mobile devices, we are particularly dependent
on the interoperability of our products and services with mobile devices and operating systems in order to deliver our
products and services. We also may not be successful in developing relationships with key participants in the mobile
industry or in developing products or services that operate effectively with these operating systems, networks, devices,
web browsers and standards. In the event that it is difficult for our users to access and use our products and services,
particularly on their mobile devices, our mDAU could be harmed, and our business and operating results could be
adversely affected.
Our products and services may contain undetected software errors, which could harm our business and
operating results.
Our products and services incorporate complex software and we encourage employees to quickly develop and help
us launch new and innovative features. Our software, including any open source software that is incorporated into our
code, has contained, and may now or in the future contain, errors, bugs or vulnerabilities. For example, in May 2018, we
announced that an internal bug had resulted in the storage of passwords unmasked in an internal log. When users set a
password for their Twitter accounts, we secure those passwords in a format that prevents anyone at Twitter from seeing
or knowing the actual password through a password hashing function, which replaces the actual password with a random
set of numbers and letters that are stored in Twitter’s system. Due to a bug, passwords were written to a service log
before completing the hashing process. We found this error ourselves, removed the passwords from the logs, and are
implementing plans to prevent this bug from happening again. Our investigation shows no indication of breach or misuse
by anyone. In September 2018, we announced an internal bug related to our Account Activity API, which allows registered
developers to build customer support and engagement tools for businesses and others on Twitter. This bug may have
caused some of the customer communications and engagements with businesses and others on Twitter to be
unintentionally sent to another registered developer. Although our initial analysis indicates that a complex series of
technical circumstances had to occur at the same time for this bug to have resulted in account information definitively
being shared with the wrong recipient, we contacted our developer partners to ensure that they are complying with their
obligations to delete information they should not have in their possession. As was the case with these errors, errors in our
software code may only be discovered after the product or service has been released. Errors, vulnerabilities, or other
design defects within the software on which we rely may result in a negative experience for users, partners and
advertisers who use our products, delay product introductions or enhancements, result in targeting, measurement, or
billing errors, compromise our ability to protect the data of our users and/or our intellectual property or lead to reductions
in our ability to provide some or all of our services. Any errors, bugs or vulnerabilities discovered in our code after release
could result in damage to our reputation, loss of users, loss of content or platform partners, loss of advertisers or
advertising revenue or liability for damages or other relief sought in lawsuits, regulatory inquiries or other proceedings, any
of which could adversely affect our business and operating results.
20
Our ability to convince potential and new users of the value of our products and services is critical to increasing
our user base and to the success of our business.
We have developed a global platform that we believe is the best and fastest place to see what’s happening and what
people are talking about all around the world, but the market for our products and services is relatively new and may not
develop as expected, if at all. Despite our efforts to reduce barriers to consumption, people who are not our users may not
understand the value of our products and services and new users may initially find our products confusing, which may
make retention of such users more difficult. There may be a perception that our products and services are only useful to
users who Tweet, or to influential users with large audiences. Convincing potential and new users of the value of our
products and services is critical to increasing our user base, user engagement and to the success of our business.
If we fail to educate potential users and potential advertisers about the value of our products and services, if the
market for our platform does not develop as we expect or if we fail to address the needs of this market, our business will
be harmed. Failure to adequately address these risks and challenges could harm our business and cause our operating
results to suffer.
Our business depends on continued and unimpeded access to our products and services on the Internet by our
users, content partners, advertisers, and platform partners. If we or our users experience disruptions in Internet
service or if Internet service providers are able to block, degrade or charge for access to our products and
services, we could incur additional expenses and the loss of users and advertisers.
We depend on the ability of our users, content partners, advertisers and platform partners to access the Internet.
Currently, this access is provided by companies that have significant market power in the broadband and Internet access
marketplace, including incumbent telephone companies, cable companies, mobile communications companies,
government-owned service providers, device manufacturers and operating system providers, any of whom could take
actions that degrade, disrupt or increase the cost of user access to our products or services, which would, in turn,
negatively impact our business. The adoption or repeal of any laws or regulations that adversely affect the growth,
popularity or use of the Internet, including laws or practices limiting Internet neutrality, could decrease the demand for, or
the usage of, our products and services, increase our cost of doing business and adversely affect our operating results.
For example, access to Twitter is blocked in China and has been intermittently blocked in Turkey in the past and certain of
our SMS messages have been blocked in Saudi Arabia. We also rely on other companies to maintain reliable network
systems that provide adequate speed, data capacity and security to us and our users. As the Internet continues to
experience growth in the number of users, frequency of use and amount of data transmitted, the Internet infrastructure
that we and our users rely on may be unable to support the demands placed upon it. The failure of the Internet
infrastructure that we or our users rely on, even for a short period of time, could undermine our operations and harm our
operating results.
21
Our new products, product features, services and initiatives and changes to existing products, services and
initiatives could fail to attract users, content partners, advertisers and platform partners or generate revenue.
Our industry is subject to rapid and frequent changes in technology, evolving customer needs and the frequent
introduction by our competitors of new and enhanced offerings. We must constantly assess the playing field and
determine whether we need to improve or re-allocate resources amongst our existing products and services or create new
ones (independently or in conjunction with third parties). Our ability to increase the size and engagement of our user base,
attract content partners, advertisers and platform partners and generate revenue will depend on those decisions. We may
introduce significant changes to our existing products and services or develop and introduce new and unproven products
and services, including technologies with which we have little or no prior development or operating experience. For
example, in 2015, we introduced Periscope, a mobile application that lets users share and experience live video from their
mobile phones and in 2013, we introduced Vine, a mobile application that enabled users to create and distribute videos
that are up to six seconds in length, which we discontinued in January 2017. Also, we introduced new features to Twitter
such as “Moments”, a curated collection of Tweets, photos, videos, and Periscope broadcasts about current news stories
or events; “In Case You Missed It,” which surfaces Tweets a logged-in user may have missed since last accessing
Twitter; expanding our character limit to 280 characters for more people around the world; and “Threads,” a new feature
that allows people to more easily thread Tweets together. If new or enhanced products, product features or services fail to
engage users, content partners and advertisers, we may fail to attract or retain users or to generate sufficient revenue or
operating profit to justify our investments, and our business and operating results could be adversely affected. In addition,
we have launched and expect to continue to launch strategic initiatives that do not directly generate revenue but which we
believe will enhance our attractiveness to users, content partners and advertisers, such as our investments in the health
of public conversation on Twitter. In the future, we may invest in new products, product features, services and initiatives to
generate revenue, but there is no guarantee these approaches will be successful. We may not be successful in future
efforts to generate revenue from our new products or services. If our strategic initiatives do not enhance our ability to
monetize our existing products and services, enable us to develop new approaches to monetization or meet the
expectations of our users or third-party business partners, we may not be able to maintain or grow our revenue or recover
any associated development costs and our operating results could be adversely affected.
If we fail to effectively manage changes to our business and operations, our business and operating results
could be harmed.
Providing our products and services to our users is costly and we expect certain of our expenses to continue to
increase in the future as we broaden our user base and increase user engagement, as users increase the amount of
content they contribute, and as we develop and implement new features, products and services that require more
infrastructure, in particular our video product features. Historically, our operating expenses, such as our research and
development expenses and sales and marketing expenses, have grown each year as we have expanded our business.
As a result, our costs have increased each year due to these factors and we expect to continue to incur increasing costs
to support our operations. We expect to continue to invest in our infrastructure so that we can provide our products and
services rapidly and reliably to users around the world, including in countries where we do not expect significant near-term
monetization.
We intend to fully invest in our highest priorities, while eliminating investment in noncore areas. Finding and
maintaining the appropriate balance will require significant expenditures and allocation of valuable management
resources. If we fail to achieve the necessary level of efficiency in our organization, our business, operating results and
financial condition would be harmed.
22
We focus on the long-term health of our platform, product innovation, and providing something valuable to
people on Twitter every day, rather than short-term operating results.
We encourage employees to quickly develop and help us launch new and innovative features. We focus on
improving the user experience for our products and services, which includes protecting user privacy, and on developing
new and improved products and services for the advertisers on our platform. For example, we are making investments in
improving the health of the public conversation on Twitter, focusing on the long-term health of the platform over near-term
metrics. We prioritize innovation and the experience for users and advertisers on our platform over short-term operating
results. We frequently make product, product feature and service decisions that may reduce our short-term operating
results if we believe that the decisions are consistent with our goals to improve the user experience and performance for
advertisers, which we believe will improve our operating results over the long term. For example, we are investing in our
live-streaming video experiences, and we may not successfully monetize such experiences. These decisions may not be
consistent with the short-term expectations of investors and may not produce the long-term benefits that we expect, in
which case our user growth and user engagement, our relationships with advertisers and our business and operating
results could be harmed. In addition, our focus on the user experience may negatively impact our relationships with our
existing or prospective advertisers. This could result in a loss of advertisers, which could harm our revenue and operating
results.
Our business and operating results may be harmed by a disruption in our service, or by our failure to timely and
effectively scale and adapt our existing technology and infrastructure.
One of the reasons people come to Twitter every day is for real-time information. We have experienced, and may in
the future experience, service disruptions, outages and other performance problems due to a variety of factors, including
infrastructure changes, human or software errors, hardware failure, capacity constraints due to an overwhelming number
of people accessing our products and services simultaneously, computer viruses and denial of service or fraud or security
attacks. For instance, in the past, we have experienced brief service outages during which Twitter.com and Twitter mobile
clients were inaccessible as a result, in part, of software misconfigurations. Additionally, although we are investing
significantly to improve the capacity, capability and reliability of our infrastructure, we are not currently serving traffic
equally through our co-located data centers that support our platform. Accordingly, in the event of a significant issue at the
data center supporting most of our network traffic, some of our products and services may become inaccessible to the
public or the public may experience difficulties accessing our products and services. Any disruption or failure in our
infrastructure could hinder our ability to handle existing or increased traffic on our platform, which could significantly harm
our business.
We utilize third-party cloud computing services in connection with certain aspects of our business and operations,
and any disruption of, or interference with, our use of such cloud services could adversely impact our business and
operations.
As our user base expands and our users generate more content, including photos and videos hosted by Twitter, we
may be required to expand and adapt our technology and infrastructure to continue to reliably store, serve and analyze
this content. It may become increasingly difficult to maintain and improve the performance of our products and services,
especially during peak usage times, as our products and services become more complex and our user traffic increases. In
addition, because we lease our data center facilities, we cannot be assured that we will be able to expand our data center
infrastructure to meet user demand in a timely manner, or on favorable economic terms. If our users are unable to access
Twitter or we are not able to make information available rapidly on Twitter, users may seek other channels to obtain the
information, and may not return to Twitter or use Twitter as often in the future, or at all. This would negatively impact our
ability to attract users, content partners and advertisers and increase the frequency of users returning to Twitter. We
expect to continue to make significant investments to maintain and improve the capacity, capability and reliability of our
infrastructure. To the extent that we do not effectively address capacity constraints, upgrade our systems as needed and
continually develop our technology and infrastructure to accommodate actual and anticipated changes in technology, our
business and operating results may be harmed.
We continue to scale the capacity of, and enhance the capability and reliability of, our infrastructure to support user
growth and increased activity on our platform. As our user base and the activity on our platform grow, we expect that
investments and expenses associated with our infrastructure will continue to grow. These investments and expenses
include the expansion and improvement of our data center operations and related operating costs, additional servers and
networking equipment to increase the capacity of our infrastructure, increased utilization of third-party cloud computing
and associated costs thereof, increased bandwidth costs, and costs to secure our customers’ data. The improvement of
our infrastructure requires a significant investment of our management’s time and our financial resources.
23
We have incurred significant operating losses in the past, and we may not be able to maintain profitability.
Since our inception, we have incurred significant operating losses, and, as of December 31, 2018, we had an
accumulated deficit of $1.45 billion. Our revenue has grown from $664.9 million in 2013 to $3.04 billion in 2018. While we
were profitable on a GAAP basis in 2018, we believe that our future revenue growth and our ability to maintain profitability
will depend on, among other factors, our ability to attract new users, increase user engagement and ad engagement,
increase our brand awareness, compete effectively, maximize our sales efforts, demonstrate a positive return on
investment for advertisers, and successfully develop new products and services. Accordingly, you should not rely on the
revenue growth of any prior quarterly or annual period as an indication of our future performance. Our costs may increase
in future periods as we continue to expend substantial financial resources on:
•
•
•
•
•
•
our technology infrastructure;
research and development for our products and services;
sales and marketing;
attracting and retaining talented employees;
strategic opportunities, including commercial relationships and acquisitions; and
general administration, including personnel costs and legal and accounting expenses related to being a public
company.
These investments may not result in increased revenue or growth in our business. Additionally, certain new revenue
products or product features may carry higher costs relative to our other products, which may decrease our margins. If we
are unable to generate adequate revenue growth and to manage our expenses, we may incur significant losses in the
future and may not be able to maintain profitability.
If we are unable to maintain and promote our brand, our business and operating results may be harmed.
We believe that maintaining and promoting our brand is critical to expanding our base of users, content partners and
advertisers. Maintaining and promoting our brand will depend largely on our ability to continue to provide useful, reliable
and innovative products and services with a focus on a positive user experience, which we may not do successfully. We
may introduce new features, products, services or terms of service that users, content partners, advertisers or platform
partners do not like, which may negatively affect our brand. Additionally, the actions of content partners may affect our
brand if users do not have a positive experience using third-party applications or websites integrated with Twitter or that
make use of Twitter content. We will also continue to experience media, legislative or regulatory scrutiny of our decisions
regarding user privacy, security, content and other issues, which may adversely affect our reputation and brand. For
example, we previously announced our discovery of content (including some advertisements) displayed on our products
that may be relevant to government investigations relating to Russian interference in the 2016 U.S. presidential election,
which continues to draw media and regulatory scrutiny of our actions with respect to such content. Our brand may also be
negatively affected by the actions of users that are hostile or inappropriate to other people, by users impersonating other
people, by users identified as spam, by use or perceived use, directly or indirectly, of our products or services by users
(including governments and government-sponsored actors) to disseminate information that may be viewed as misleading
(or intended to manipulate the opinions of our users), by users introducing excessive amounts of spam on our platform, by
third parties obtaining control over users’ accounts or by other security or cybersecurity incidents. For example, certain
actions taken by a social media marketing company in the past to sell followers and engagement, which were in violation
of our policies, but that drew media and regulatory scrutiny on us. Maintaining and enhancing our brand may require us to
make substantial investments and these investments may not achieve the desired goals. If we fail to successfully promote
and maintain our brand or if we incur excessive expenses in this effort, our business and operating results could be
adversely affected.
24
Negative publicity could adversely affect our business and operating results.
We receive a high degree of media coverage around the world. Negative publicity about our company, including
about the quality and reliability of our products or of content shared on our platform, changes to our products and
services, our privacy and security practices (including actions taken with respect to certain users or accounts or reports
regarding government surveillance), litigation, regulatory activity, the actions of our users (including actions taken by
prominent users on our platform or the dissemination of information that may be viewed as misleading or as intended to
manipulate the opinions of our users), or user experience with our products and services, even if inaccurate, could
adversely affect our reputation and the confidence in and the use of our products and services. Such negative publicity
could also have an adverse effect on the size, engagement and loyalty of our user base and result in decreased revenue,
which could adversely affect our business and operating results.
Spam and fake accounts could diminish the user experience on our platform, which could damage our reputation
and deter our current and potential users from using our products and services.
“Spam” on Twitter refers to a range of abusive activities that are prohibited by our terms of service and is generally
defined as unsolicited, repeated actions that negatively impact other users with the general goal of drawing user attention
to a given account, site, product or idea. This includes posting large numbers of unsolicited mentions of a user, duplicate
Tweets, malicious automation, misleading links (e.g., to malware or “click-jacking” pages) or other false or misleading
content, and aggressively following and un-following accounts, adding users to lists, sending invitations, Retweeting and
liking Tweets to inappropriately attract attention. Our terms of service also prohibit the creation of serial or bulk accounts,
both manually or using automation, for disruptive or abusive purposes, such as to Tweet spam or to artificially inflate the
popularity of users seeking to promote themselves on Twitter. Although we continue to invest resources to reduce spam
and fake accounts on Twitter, which includes our investments to improve the health of the public conversation on Twitter,
we expect spammers will continue to seek ways to act inappropriately on our platform. In addition, we expect that
increases in the number of users on our platform will result in increased efforts by spammers to misuse our platform. We
continuously combat spam and fake accounts, including by suspending or terminating accounts we believe to be
spammers and launching algorithmic changes focused on curbing abusive activities. Our actions to combat spam and
fake accounts require significant resources and time. If spam and fake accounts increase on Twitter, this could hurt our
reputation for delivering relevant content or reduce user growth rate and user engagement and result in continuing
operational cost to us.
25
Action by governments to restrict access to our products and services or censor Twitter content could harm our
business and operating results.
Governments have sought, and may in the future seek, to censor content available through our products and
services, restrict access to our products and services from their country entirely or impose other restrictions that may
affect the accessibility of our products and services for an extended period of time or indefinitely. For example, domestic
Internet service providers in China have blocked access to Twitter, and other countries, including Iran, Libya, Pakistan,
Turkey and Syria, have intermittently restricted access to Twitter, and we believe that access to Twitter has been blocked
in these countries primarily for political reasons. In addition, governments in these or other countries may seek to restrict
access to our products and services based on our decisions around user content, providing user information in response
to governmental requests, or other matters. In the event that access to our products and services is restricted, in whole or
in part, in one or more countries or our competitors are able to successfully penetrate geographic markets that we cannot
access, our ability to retain or increase our user base and user engagement may be adversely affected, and our operating
results may be harmed.
If our security measures are breached, or if our products and services are subject to attacks that degrade or deny
the ability of users to access our products and services, our products and services may be perceived as not
being secure, users and advertisers may curtail or stop using our products and services and our business and
operating results could be harmed.
Our products and services involve the storage and transmission of users’ and advertisers’ information, and security
breaches expose us to a risk of loss of this information, litigation, increased security costs and potential liability. We also
work with third-party vendors to process credit card payments by our customers and are subject to payment card
association operating rules. We and our third-party service providers experience cyber-attacks of varying degrees on a
regular basis. For example, in October 2016, we experienced a service outage as a result of several distributed denial of
service attacks on our domain name service provider, Dyn.
Our products operate in conjunction with, and we are dependent upon, third-party products and components across
a broad ecosystem. Additionally, the natural sunsetting of third-party products and operating systems that we use requires
that our infrastructure teams reallocate time and attention to migration and updates, during which period potential security
vulnerabilities could be exploited. If there is a security vulnerability (such as the Spectre and Meltdown vulnerabilities) in
one of these components and if there is a security exploit targeting it, we could face increased costs, liability claims,
reduced revenue, or harm to our reputation or competitive position.
Third parties may also gain access to Twitter user names and passwords without attacking Twitter directly by
combining credential information from other recent breaches, using malware on victim machines that are stealing
passwords for all sites, or a combination of both. In addition, some of our developers or other partners, such as third-party
applications to which our users have given permission to Tweet on their behalf, may receive or store information provided
by us or by our users through mobile or web applications integrated with us. If these third parties or developers fail to
adopt or adhere to adequate data security practices, or in the event of a breach of their networks, our data or our users'
data may be improperly accessed, used, or disclosed.
As a result, unauthorized parties have obtained, and may in the future obtain, access to our data or our users’ or
advertisers’ data. In addition, a breach of a third-party application that has been trusted by a user could result in the
account issuing Tweets, Likes, Retweets, or Direct Messages without such user’s knowledge or consent. Any systems
failure or actual or perceived compromise of our security that results in the unauthorized access to or release of our users’
or advertisers’ data, such as credit card data, could significantly limit the adoption of our products and services, as well as
harm our reputation and brand and, therefore, our business.
26
Our security measures may also be breached due to employee error, malfeasance or otherwise. Additionally,
outside parties may attempt to fraudulently induce employees, users or advertisers to disclose sensitive information in
order to gain access to our data or our users’ or advertisers’ data or accounts, or may otherwise obtain access to such
data or accounts. Since our users and advertisers may use their Twitter accounts to establish and maintain online
identities, unauthorized communications from Twitter accounts that have been compromised may damage their personal
security, reputations and brands as well as our reputation and brand. Because the techniques used to obtain unauthorized
access, disable or degrade service or sabotage systems change frequently and often are not recognized until launched
against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. We
expect to incur significant costs in an effort to detect and prevent security breaches and other security-related incidents,
and we may face increased costs in the event of an actual or perceived security breach or other security-related incident.
If an actual or perceived breach of our security occurs, the market perception of the effectiveness of our security
measures could be harmed, our users and advertisers may be harmed, lose trust and confidence in us, decrease the use
of our products and services or stop using our products and services in their entirety. We may also incur significant legal
and financial exposure, including legal claims, higher transaction fees and regulatory fines and penalties. Any of these
actions could have a material and adverse effect on our business, reputation and operating results.
While our insurance policies include liability coverage for certain of these matters, if we experienced a significant
security incident, we could be subject to liability or other damages that exceed our insurance coverage.
Our future performance depends in part on support from our content partners and data partners.
We believe user engagement with our products and services depends in part on the availability of applications and
content generated by our content or platform partners. There is no assurance that our content or platform partners will
continue to develop and maintain applications and content for our products and services, and if they cease to, then user
engagement may decline. In addition, we generate revenue from licensing our historical and real-time data to third parties.
If any of these relationships are terminated or not renewed on economic and other terms that are acceptable to us, or if
we are unable to enter into similar relationships in the future, our operating results could be adversely affected.
Our international operations are subject to increased challenges and risks.
We have offices around the world and our products and services are available in multiple languages. However, our
ability to manage our business and conduct our operations internationally requires considerable management attention
and resources and is subject to the particular challenges of supporting a rapidly growing business in an environment of
multiple languages, cultures, customs, legal and regulatory systems, alternative dispute systems and commercial
markets. Our international operations have required and will continue to require us to invest significant funds and other
resources. Operating internationally subjects us to new risks and may increase risks that we currently face, including risks
associated with:
•
•
•
•
•
•
•
recruiting and retaining talented and capable employees in foreign countries and maintaining our company
culture across all of our offices;
providing our products and services and operating across a significant distance, in different languages and
among different cultures, including the potential need to modify our products, services, content and features to
ensure that they are culturally relevant in different countries;
increased competition from largely regional websites, mobile applications and services that provide real-time
communications and have strong positions in particular countries, which have expanded and may continue to
expand their geographic footprint;
differing and potentially lower levels of user growth, user engagement and ad engagement in new and
emerging geographies;
different levels of advertiser demand;
greater difficulty in monetizing our products and services;
compliance with applicable foreign laws and regulations, including laws and regulations with respect to privacy,
data security, consumer protection, copyright, fake news, hate speech, spam and content, and the risk of
penalties to our users and individual members of management if our practices are deemed to be out of
compliance;
27
•
•
•
•
•
•
•
•
•
•
burdens of complying with various foreign laws, including laws related to taxation, content removal, data
localization, and regulatory oversight;
longer payment cycles in some countries;
credit risk and higher levels of payment fraud;
operating in jurisdictions that do not protect intellectual property rights to the same extent as the United States;
compliance with anti-bribery laws including, without limitation, compliance with the Foreign Corrupt Practices
Act and the U.K. Bribery Act, including by our business partners;
currency exchange rate fluctuations;
foreign exchange controls that might require significant lead time in setting up operations in certain geographic
territories and might prevent us from repatriating cash earned outside the United States;
political and economic instability in some countries;
double taxation of our international earnings and potentially adverse tax consequences due to changes in the
tax laws of the United States or the foreign jurisdictions in which we operate; and
higher costs of doing business internationally, including increased accounting, travel, infrastructure and legal
compliance costs.
If we are unable to manage the complexity of our global operations successfully, our business, financial condition
and operating results could be adversely affected.
Our business is subject to complex and evolving U.S. and foreign laws and regulations. These laws and
regulations are subject to change and uncertain interpretation, and could result in claims, changes to our
business practices, monetary penalties, increased cost of operations or declines in user growth, user
engagement or ad engagement, or otherwise harm our business.
We are subject to a variety of laws and regulations in the United States and abroad that involve matters central to
our business, including privacy, security, rights of publicity, data protection, content regulation, intellectual property,
competition, protection of minors, consumer protection, credit card processing and taxation. Many of these laws and
regulations are still evolving and being tested in courts. As a result, it is possible that these laws and regulations may be
interpreted and applied in a manner that is inconsistent from country to country and inconsistent with our current policies
and practices and in ways that could harm our business, particularly in the new and rapidly evolving industry in which we
operate. Additionally, the introduction of new products or services may subject us to additional laws and regulations.
28
From time to time, governments, regulators and others have expressed concerns about whether our products,
services or practices compromise the privacy of users and others. While we strive to comply with applicable data
protection laws and regulations, as well as our own posted privacy policies and other obligations we may have with
respect to privacy and data protection, the failure or perceived failure to so comply may result, and in some cases has
resulted, in inquiries and other proceedings or actions against us by governments, regulators or others. A number of
proposals have recently been adopted or are currently pending before federal, state and foreign legislative and regulatory
bodies that could significantly affect our business. For example, in June 2018 California recently enacted legislation, the
California Consumer Privacy Act, or CCPA, that will, among other things, require covered companies to provide new
disclosures to California consumers, and afford such consumers new abilities to opt-out of certain sales of personal
information, when it goes into effect on January 1, 2020. The CCPA was amended in September 2018, and it remains
unclear what, if any, modifications will be made to this legislation or how it will be interpreted. Moreover, foreign data
protection, privacy, consumer protection, content regulation and other laws and regulations are often more restrictive than
those in the United States. In particular, the European Union, or EU, and its member states traditionally have taken
broader views as to types of data that are subject to privacy and data protection, and have imposed greater legal
obligations on companies in this regard. For example, the GDPR has been adopted and went into effect in May 2018. The
GDPR includes more stringent operational requirements for entities processing personal information and significant
penalties for non-compliance, including fines of up to €20 million or 4% of total worldwide revenue, whichever is higher.
Additionally, we rely on a variety of legal bases to transfer certain personal information outside of the European Economic
Area, including the EU-U.S. Privacy Shield Framework, the Swiss-U.S. Privacy Shield Framework, and EU Standard
Contractual Clauses, or SCCs. The EU-U.S. Privacy Shield Framework is currently under review by regulatory authorities
and it and the SCCs are both the subject of legal challenges in European courts, and they may be modified or invalidated.
The absence of successor legal bases for continued data transfer could require us to create duplicative, and potentially
expensive, information technology infrastructure and business operations in Europe or limit our ability to collect and use
personal information collected in Europe. Any of these changes with respect to EU data protection law could disrupt our
business.
Further, following a referendum in June 2016 in which voters in the United Kingdom approved an exit from the EU,
the United Kingdom government has initiated a process to leave the EU (often referred to as “Brexit”). Without further
agreement between the United Kingdom and the EU, the United Kingdom will formally leave the EU in March 2019. Brexit
could lead to economic and legal uncertainty in the region and could adversely affect the tax, currency, operational, legal
and regulatory regimes to which our business is subject. Brexit may adversely affect our revenues and subject us to new
regulatory costs and challenges, in addition to other adverse effects that we are unable effectively to anticipate.
The United Kingdom recently implemented a Data Protection Bill that substantially implements the GDPR, which
became law in May 2018. Brexit has created uncertainty with regard to whether the EU will view the UK data protection
regulation as adequate under GDPR. Until that is resolved, the requirements for data transfers between the United
Kingdom and the EU are unclear.
Legislative changes in the United States, at both the federal and state level, that could impose new obligations in
areas such as privacy and liability for copyright infringement or content by third parties such as various Congressional
efforts to restrict the scope of the protections available to online platforms under Section 230 of the Communications
Decency Act, and our current protections from liability for third-party content in the United States could decrease or
change. Additionally, recent amendments to U.S. patent laws may affect the ability of companies, including us, to protect
their innovations and defend against claims of patent infringement.
Similarly, the EU’s proposed Directive on Copyright in the Digital Single Market (the EU Copyright Directive), if
enacted as currently proposed, would expand the liability of online platforms for user-generated content and would
obligate platforms to negotiate licenses with rightsholders and ensure that unauthorized copyrighted material is not
available on their platforms. The EU Copyright Directive would also give publishers rights over snippets of news content
displayed online and restrict platforms’ ability to display such material. If enacted, the EU Copyright Directive would
increase our costs of operations and increase our liability for user-generated content.
29
Additionally, we have relationships with third parties that perform a variety of functions such as payments
processing, tokenization, vaulting, currency conversion, fraud prevention and data security audits. The laws and
regulations related to online payments are complex, subject to change, and vary across different jurisdictions in the United
States and globally. As a result, we may be required to spend significant time, effort and expense to comply with
applicable laws and regulations. Any failure or claim of our failure to comply, or any failure or claim of failure by the above-
mentioned third parties to comply, could increase our costs or could result in liabilities. Additionally, because Twitter
accepts payment via credit cards and is certified as a PCI Level 1 service provider, we are subject to payment card
association operating rules and certification requirements, including the Payment Card Industry Data Security Standard.
We currently allow use of our platform without the collection of extensive personal information, such as age. We may
experience additional pressure to expand our collection of personal information in order to comply with new and additional
regulatory demands or we may independently decide to do so. If we obtain such additional personal information, we may
be subject to additional regulation.
Regulatory investigations and settlements could cause us to incur additional expenses or change our business
practices in a manner materially adverse to our business.
We are currently the subject of inquiries by the Irish Data Protection Commission with respect to our compliance with
the GDPR and expect to continue to be subject to regulatory scrutiny as our business grows and awareness of our brand
increases, In the past, we have been subject to regulatory investigations, and expect to continue to be subject to
regulatory scrutiny as our business grows and awareness of our brand increases. In March 2011, to resolve an
investigation into various incidents, we entered into a settlement agreement with the FTC that, among other things,
required us to establish an information security program designed to protect non-public consumer information and also
requires that we obtain biennial independent security assessments. The obligations under the settlement agreement
remain in effect until the later of March 2, 2031, or the date 20 years after the date, if any, on which the U.S. government
or the FTC files a complaint in federal court alleging any violation of the order. We expect to continue to be the subject of
regulatory inquiries, investigations and audits in the future by the FTC and other regulators around the world.
It is possible that a regulatory inquiry, investigation or audit might result in changes to our policies or practices, and
may cause us to incur substantial costs or could result in reputational harm, prevent us from offering certain products,
services, features or functionalities, cause us to incur substantial costs or require us to change our business practices in a
manner materially adverse to our business. Violation of existing or future regulatory orders, settlements or consent
decrees could subject us to substantial monetary fines and other penalties that could negatively affect our financial
condition and operating results.
We may face lawsuits or incur liability as a result of content published or made available through our products
and services.
We have faced and will continue to face claims relating to content that is published or made available through our
products and services or third-party products or services. In particular, the nature of our business exposes us to claims
related to defamation, intellectual property rights, rights of publicity and privacy, illegal content, misinformation, content
regulation and personal injury torts. The laws relating to the liability of providers of online products or services for activities
of their users remains somewhat unsettled, both within the United States and internationally. This risk may be enhanced
in certain jurisdictions outside the United States where we may be less protected under local laws than we are in the
United States. For example, we are subject to legislation in Germany that may impose significant fines for failure to
comply with certain content removal and disclosure obligations. In addition, the public nature of communications on our
network exposes us to risks arising from the creation of impersonation accounts intended to be attributed to our users or
advertisers. We could incur significant costs investigating and defending these claims. If we incur material costs or liability
as a result of these occurrences, our business, financial condition and operating results could be adversely affected.
30
Our intellectual property rights are valuable, and any inability to protect them could reduce the value of our
products, services and brand.
Our trade secrets, trademarks, copyrights, patents and other intellectual property rights are important assets. We
rely on, and expect to continue to rely on, a combination of confidentiality and license agreements with our employees,
consultants and third parties with whom we have relationships, as well as trademark, trade dress, domain name,
copyright, trade secret and patent laws, to protect our brand and other intellectual property rights. However, various
events outside of our control pose a threat to our intellectual property rights, as well as to our products, services and
technologies. For example, we may fail to obtain effective intellectual property protection, or effective intellectual property
protection may not be available in every country in which our products and services are available. Also, the efforts we
have taken to protect our intellectual property rights may not be sufficient or effective, and any of our intellectual property
rights may be challenged, which could result in them being narrowed in scope or declared invalid or unenforceable. There
can be no assurance our intellectual property rights will be sufficient to protect against others offering products or services
that are substantially similar to ours and compete with our business.
We rely on non-patented proprietary information and technology, such as trade secrets, confidential information,
know-how and technical information. While in certain cases we have agreements in place with employees and third
parties that place restrictions on the use and disclosure of this intellectual property, these agreements may be breached,
or this intellectual property may otherwise be disclosed or become known to our competitors, including through hacking or
theft, which could cause us to lose any competitive advantage resulting from this intellectual property.
We are pursuing registration of trademarks and domain names in the United States and in certain jurisdictions
outside of the United States. Effective protection of trademarks and domain names is expensive and difficult to maintain,
both in terms of application and registration costs as well as the costs of defending and enforcing those rights. We may be
required to protect our rights in an increasing number of countries, a process that is expensive and may not be successful
or which we may not pursue in every country in which our products and services are distributed or made available.
We are party to numerous agreements that grant licenses to third parties to use our intellectual property, including
our trademarks. For example, many third parties distribute their content through Twitter, or embed Twitter content in their
applications or on their websites, and make use of our trademarks in connection with their services. If the licensees of our
trademarks are not using our trademarks properly, it may limit our ability to protect our trademarks and could ultimately
result in our trademarks being declared invalid or unenforceable. We have a policy designed to assist third parties in the
proper use of our brand, trademarks and other assets, and we have an internal team dedicated to enforcing our policy and
protecting our brand. Our brand protection team routinely receives and reviews reports of improper and unauthorized use
of the Twitter brand, trademarks or assets and issues takedown notices or initiates discussions with the third parties to
correct the issues. However, there can be no assurance that we will be able to protect against the unauthorized use of our
brand, trademarks or other assets. If we fail to maintain and enforce our trademark rights, the value of our brand could be
diminished. There is also a risk that one or more of our trademarks could become generic, which could result in them
being declared invalid or unenforceable. For example, there is a risk that the word “Tweet” could become so commonly
used that it becomes synonymous with any short comment posted publicly on the Internet, and if this happens, we could
lose protection of this trademark.
We also seek to obtain patent protection for some of our technology. We may be unable to obtain patent protection
for our technologies, and our existing patents, and any patents that may be issued in the future, may not provide us with
competitive advantages or distinguish our products and services from those of our competitors. In addition, any patents
may be contested, circumvented, or found unenforceable or invalid, and we may not be able to prevent third parties from
infringing or otherwise violating them. Effective protection of patent rights is expensive and difficult to maintain, both in
terms of application and maintenance costs, as well as the costs of defending and enforcing those rights.
31
Our Innovator’s Patent Agreement, or IPA, also can limit our ability to prevent infringement of our patents. In May
2013, we implemented the IPA, which we enter into with our employees and consultants, including our founders. The IPA,
which applies to our current and future patents, allows us to assert our patents defensively. The IPA also allows us to
assert our patents offensively with the permission of the inventors of the applicable patent. Under the IPA, an assertion of
claims is considered for a defensive purpose if the claims are asserted: (i) against an entity that has filed, maintained,
threatened or voluntarily participated in a patent infringement lawsuit against us or any of our users, affiliates, customers,
suppliers or distributors; (ii) against an entity that has used its patents offensively against any other party in the past ten
years, so long as the entity has not instituted the patent infringement lawsuit defensively in response to a patent litigation
threat against the entity; or (iii) otherwise to deter a patent litigation threat against us or our users, affiliates, customers,
suppliers or distributors. In addition, the IPA provides that the above limitations apply to any future owner or exclusive
licensee of any of our patents, which could limit our ability to sell or license our patents to third parties. While we may be
able to claim protection of our intellectual property under other rights, such as trade secrets or contractual obligations with
our employees not to disclose or use confidential information, we may be unable to assert our patent rights against third
parties that we believe are infringing our patents, even if such third parties are developing products and services that
compete with our products and services. For example, in the event that an inventor of one of our patents leaves us for
another company and uses our patented technology to compete with us, we would not be able to assert that patent
against such other company unless the assertion of the patent right is for a defensive purpose. In such event, we may be
limited in our ability to assert a patent right against another company, and instead would need to rely on trade secret
protection or the contractual obligation of the inventor to us not to disclose or use our confidential information. In addition,
the terms of the IPA could affect our ability to monetize our intellectual property portfolio.
Significant impairments of our intellectual property rights, and limitations on our ability to assert our intellectual
property rights against others, could harm our business and our ability to compete.
Also, obtaining, maintaining and enforcing our intellectual property rights is costly and time consuming. Any increase
in the unauthorized use of our intellectual property could make it more expensive to do business and harm our operating
results.
We are currently, and expect to be in the future, party to intellectual property rights claims that are expensive and
time consuming to defend, and, if resolved adversely, could have a significant impact on our business, financial
condition or operating results.
Companies in the internet, technology and media industries are subject to litigation based on allegations of
infringement, misappropriation or other violations of intellectual property or other rights. Many companies in these
industries, including many of our competitors, have substantially larger patent and intellectual property portfolios than we
do, which could make us a target for litigation as we may not be able to assert counterclaims against parties that sue us
for patent, or other intellectual property infringement. In addition, various “non-practicing entities” that own patents and
other intellectual property rights often attempt to assert claims in order to extract value from technology companies. From
time to time we receive claims from third parties which allege that we have infringed upon their intellectual property rights.
Further, from time to time we may introduce new products, product features and services, including in areas where we
currently do not have an offering, which could increase our exposure to patent and other intellectual property claims from
competitors and non-practicing entities. In addition, although our standard terms and conditions for our Promoted
Products and public APIs do not provide advertisers and platform partners with indemnification for intellectual property
claims against them, some of our agreements with advertisers, content partners, platform partners and data partners
require us to indemnify them for certain intellectual property claims against them, which could require us to incur
considerable costs in defending such claims, and may require us to pay significant damages in the event of an adverse
ruling. Such advertisers, content partners, platform partners and data partners may also discontinue use of our products,
services and technologies as a result of injunctions or otherwise, which could result in loss of revenue and adversely
impact our business.
32
We presently are involved in a number of intellectual property lawsuits, and as we face increasing competition and
develop new products, we expect the number of patent and other intellectual property claims against us may grow. There
may be intellectual property or other rights held by others, including issued or pending patents, that cover significant
aspects of our products and services, and we cannot be sure that we are not infringing or violating, and have not infringed
or violated, any third-party intellectual property rights or that we will not be held to have done so or be accused of doing so
in the future. Any claim or litigation alleging that we have infringed or otherwise violated intellectual property or other rights
of third parties, with or without merit, and whether or not settled out of court or determined in our favor, could be time-
consuming and costly to address and resolve, and could divert the time and attention of our management and technical
personnel. Some of our competitors have substantially greater resources than we do and are able to sustain the costs of
complex intellectual property litigation to a greater degree and for longer periods of time than we could. The outcome of
any litigation is inherently uncertain, and there can be no assurances that favorable final outcomes will be obtained in all
cases. In addition, plaintiffs may seek, and we may become subject to, preliminary or provisional rulings in the course of
any such litigation, including potential preliminary injunctions requiring us to cease some or all of our operations. We may
decide to settle such lawsuits and disputes on terms that are unfavorable to us. Similarly, if any litigation to which we are a
party is resolved adversely, we may be subject to an unfavorable judgment that may not be reversed upon appeal. The
terms of such a settlement or judgment may require us to cease some or all of our operations or pay substantial amounts
to the other party. In addition, we may have to seek a license to continue practices found to be in violation of a third-
party’s rights. If we are required, or choose to enter into royalty or licensing arrangements, such arrangements may not be
available on reasonable terms, or at all, and may significantly increase our operating costs and expenses. As a result, we
may also be required to develop or procure alternative non-infringing technology, which could require significant effort and
expense or discontinue use of the technology. An unfavorable resolution of the disputes and litigation referred to above
could adversely affect our business, financial condition and operating results.
Many of our products and services contain open source software, and we license some of our software through
open source projects, which may pose particular risks to our proprietary software, products, and services in a
manner that could have a negative effect on our business.
We use open source software in our products and services and will use open source software in the future. In
addition, we regularly contribute software source code to open source projects under open source licenses or release
internal software projects under open source licenses, and anticipate doing so in the future. The terms of many open
source licenses to which we are subject have not been interpreted by U.S. or foreign courts, and there is a risk that open
source software licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our
ability to provide or distribute our products or services. Additionally, we may from time to time face claims from third
parties claiming ownership of, or demanding release of, the open source software or derivative works that we developed
using such software, which could include our proprietary source code, or otherwise seeking to enforce the terms of the
applicable open source license. These claims could result in litigation and could require us to make our software source
code freely available, purchase a costly license or cease offering the implicated products or services unless and until we
can re-engineer them to avoid infringement. This re-engineering process could require significant additional research and
development resources, and we may not be able to complete it successfully. In addition to risks related to license
requirements, use of certain open source software may pose greater risks than use of third-party commercial software, as
open source licensors generally do not provide warranties or controls on the origin of software. Any of these risks could be
difficult to eliminate or manage, and, if not addressed, could have a negative effect on our business, financial condition
and operating results.
33
We rely on assumptions and estimates to calculate certain of our key metrics, and real or perceived inaccuracies
in such metrics may harm our reputation and negatively affect our business.
The number of our active users is calculated using internal company data that has not been independently verified.
While these numbers are based on what we believe to be reasonable calculations for the applicable period of
measurement, there are inherent challenges in measuring usage and user engagement across our large user base
around the world. For example, there are a number of false or spam accounts in existence on our platform. We estimate
that the average of false or spam accounts during the fourth quarter of 2018 continued to represent fewer than 5% of our
MAUs and mDAUs during the quarter. However, this estimate is based on an internal review of a sample of accounts and
we apply significant judgment in making this determination. As such, our estimation of false or spam accounts may not
accurately represent the actual number of such accounts, and the actual number of false or spam accounts could be
higher than we have currently estimated. We are continually seeking to improve our ability to estimate the total number of
spam accounts and eliminate them from the calculation of our active users, but we otherwise treat multiple accounts held
by a single person or organization as multiple users for purposes of calculating our active users because we permit
people and organizations to have more than one account. Additionally, some accounts used by organizations are used by
many people within the organization. As such, the calculations of our active users may not accurately reflect the actual
number of people or organizations using our platform. Further, we rely on third-party SMS aggregators and mobile carriers
to deliver SMS messages to certain of our MAUs. If, however, we are notified of material deliverability issues because of,
for example, infrastructure issues at the service-provider level or governmental restrictions based on content, we do not
include the affected users in MAUs. We may also discover unexpected errors in our internal data that resulted from
technical or other errors. For example, in 2017, we discovered that since the fourth quarter of 2014 we had included users
of certain third-party applications as Twitter MAUs that should not have been considered MAUs. These third-party
applications used Digits, a software development kit of our now-divested Fabric platform that allowed third-party
applications to send authentication messages via SMS through our systems, which did not relate to activity on the Twitter
platform. Although the change in the MAUs was relatively small in relation to our overall MAU numbers, we may face
increased scrutiny on the calculation of our key metrics as a result of the error.
Our calculations of MAU may be affected by mobile applications that automatically contact our servers for regular
updates with no discernable user-initiated action involved, and this activity can cause our system to count the user
associated with such a device as an active user on the day such contact occurs. The impact of this automatic activity on
MAU varies by geography because mobile application usage varies in different regions of the world. In addition, our data
regarding user geographic location is based on the IP address or phone number associated with the account when a user
initially registered the account on Twitter. That IP address or phone number may not always accurately reflect a user’s
actual location at the time of such user’s engagement on our platform.
We regularly review and may adjust our processes for calculating our internal metrics to improve their accuracy. Our
measures of user growth and user engagement may differ from estimates published by third parties or from similarly-titled
metrics of our competitors due to differences in methodology. If advertisers, content or platform partners or investors do
not perceive our user metrics to be accurate representations of our user base or user engagement, or if we discover
material inaccuracies in our user metrics, our reputation may be harmed and content partners, advertisers and platform
partners may be less willing to allocate their budgets or resources to our products and services, which could negatively
affect our business and operating results. Further, as our business develops, we may revise or cease reporting metrics if
we determine that such metrics are no longer accurate or appropriate measures of our performance. For example, we
believe that mDAU, and its related growth, are the best ways to measure our success against our objectives and to show
the size of our audience and engagement going forward, so we will discontinue disclosing MAU after the first quarter of
2019. In the past, we also stopped disclosing timeline views as we no longer believed that metric was helpful in measuring
engagement on our platform. If investors, analysts or customers do not believe our reported measures, such as mDAU,
are sufficient or accurately reflect our business, we may receive negative publicity and our operating results may be
harmed.
34
We rely in part on application marketplaces and Internet search engines to drive traffic to our products and
services, and if we fail to appear high up in the search results or rankings, traffic to our platform could decline
and our business and operating results could be adversely affected.
We rely on application marketplaces, such as Apple’s App Store and Google’s Play, to drive downloads of our
mobile applications. In the future, Apple, Google or other operators of application marketplaces may make changes to
their marketplaces which make access to our products and services more difficult or limit our use of data to provide
targeted advertising. We also depend in part on Internet search engines, such as Google, Apple Spotlight, Bing and
Yahoo, to drive traffic to our website. For example, when a user types an inquiry into a search engine, we rely on a high
organic search result ranking of our webpages in these search results to refer the user to our website. However, our ability
to maintain high organic search result rankings is not within our control. Our competitors’ search engine optimization, or
SEO, efforts may result in their websites receiving a higher search result page ranking than ours, or Internet search
engines could revise their methodologies in a way that would adversely affect our search result rankings. If internet
search engines modify their search algorithms in ways that are detrimental to us, or if our competitors’ SEO efforts are
more successful than ours, the growth in our user base could slow. Our website has experienced fluctuations in search
result rankings in the past, and we anticipate similar fluctuations in the future. Any reduction in the number of users
directed to our mobile applications or website through application marketplaces and search engines could harm our
business and operating results.
Users increasingly access our products and services through mobile and alternative devices, and we need to
continue to promote the adoption of our mobile applications, and our business and operating results may be
harmed if we are unable to do so.
In the three months ended December 31, 2018, 93% of our advertising revenue was generated from mobile devices.
Since we generate a majority of our advertising revenue through users on mobile devices, we must continue to drive
adoption of our mobile applications. However, in emerging markets like India and Pakistan, a significant portion of users
use feature phones and communicate via SMS messaging, both of which have limited functionality and neither of which
may be able to take full advantage of our products and services offered on smartphone or our website or desktop
applications. In addition, mobile users frequently change or upgrade their mobile devices. Our business and operating
results may be harmed if our users do not install our mobile application when they change or upgrade their mobile device.
Although we generate the majority of our advertising revenue from ad engagements on mobile devices, certain of our
products and services, including Promoted Trends and Promoted Accounts, receive less prominence on our mobile
applications than they do on our desktop applications. This has in the past reduced, and may in the future continue to
reduce, the amount of revenue we are able to generate from these products and services as users increasingly access
our products and services through mobile and alternative devices. In addition, as new devices and platforms are
continually being released, users may consume content in a manner that is more difficult to monetize. If we are unable to
develop products and services that are compatible with new devices and platforms, or if we are unable to drive continued
adoption of our mobile applications, our business and operating results may be harmed.
Acquisitions, divestitures and investments could disrupt our business and harm our financial condition and
operating results.
Our success will depend, in part, on our ability to expand our products, product features and services, and grow our
business in response to changing technologies, user and advertiser demands, and competitive pressures. In some
circumstances, we may determine to do so through the acquisition of complementary businesses and technologies rather
than through internal development, including, for example, our acquisitions of Periscope, a live-streaming video mobile
application, and MoPub, a mobile-focused advertising exchange. The identification of suitable acquisition candidates can
be difficult, time-consuming and costly, and we may not be able to successfully complete identified acquisitions. The risks
we face in connection with acquisitions include:
•
•
•
•
diversion of management time and focus from operating our business to addressing acquisition integration
challenges;
retention of key employees from the acquired company;
cultural challenges associated with integrating employees from the acquired company into our organization;
integration of the acquired company’s accounting, management information, human resources and other
administrative systems and processes;
35
•
•
•
•
the need to implement or improve controls, procedures, and policies at a business that prior to the acquisition
may have lacked effective controls, procedures and policies;
liability for activities of the acquired company before the acquisition, including intellectual property infringement
claims, violations of laws, commercial disputes, tax liabilities and other known and unknown liabilities;
unanticipated write-offs or charges; and
litigation or other claims in connection with the acquired company, including claims from terminated
employees, users, former stockholders or other third parties.
Our failure to address these risks or other problems encountered in connection with our past or future acquisitions
and investments could cause us to fail to realize the anticipated benefits of these acquisitions or investments, cause us to
incur unanticipated liabilities, and harm our business generally. Future acquisitions could also result in dilutive issuances
of our equity securities, the incurrence of debt, contingent liabilities, amortization expenses, incremental operating
expenses or the impairment of goodwill, any of which could harm our financial condition or operating results.
We also make investments in privately-held companies in furtherance of our strategic objectives. We may not realize
a return and may recognize a loss on such investments. Many of the instruments in which we invest are non-marketable
at the time of our initial investment. Companies in which we invest range from early-stage companies still defining their
strategic direction to more mature companies with established revenue streams and business models. The success of our
investment in any company is typically dependent on the availability to the company of additional funding on favorable
terms, or a liquidity event, such as a public offering or acquisition. If any of the companies in which we invest decrease in
value, we could lose all or part of our investment. For example, in the year ended December 31, 2017, we recorded a
$62.4 million impairment charge relating to an investment in a privately-held company.
In certain cases, we have also divested or stopped investing in certain products, including products that we
acquired. For instance, in January 2017, we divested certain assets related to our Fabric platform. In 2017, we also
deprecated certain of our revenue products, including TellApart, which was acquired in 2015. In these cases, we have
needed to and may, in the future, need to restructure operations, terminate employees and/or incur other expenses. We
may not realize the expected benefits and cost savings of these actions and our results may be harmed.
If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our
ability to produce timely and accurate financial statements or comply with applicable regulations could be
impaired.
As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as
amended, or the Exchange Act, the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, and the listing
standards of the New York Stock Exchange. The Sarbanes-Oxley Act requires, among other things, that we maintain
effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and improve
the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have
expended, and anticipate that we will continue to expend, significant resources, including accounting-related costs and
significant management oversight.
Any failure to develop or maintain effective controls, or any difficulties encountered in their implementation or
improvement, could cause us to be subject to one or more investigations or enforcement actions by state or federal
regulatory agencies, stockholder lawsuits or other adverse actions requiring us to incur defense costs, pay fines,
settlements or judgments. Any such failures could also cause investors to lose confidence in our reported financial and
other information, which would likely have a negative effect on the trading price of our common stock. In addition, if we are
unable to continue to meet these requirements, we may not be able to remain listed on the New York Stock Exchange.
36
If currency exchange rates fluctuate substantially in the future, our operating results, which are reported in U.S.
dollars, could be adversely affected.
Our international operations expose us to the effects of fluctuations in currency exchange rates. We incur expenses
for employee compensation and other operating expenses at our international locations in the local currency, and accept
payment from advertisers or data partners in currencies other than the U.S. dollar. Since we conduct business in
currencies other than U.S. dollars but report our operating results in U.S. dollars, we face exposure to fluctuations in
currency exchange rates. While we enter into foreign currency forward contracts with financial institutions to reduce the
risk that our earnings may be adversely affected by the impact of exchange rate fluctuations on monetary assets or
liabilities denominated in currencies other than the functional currency of a subsidiary, exchange rate fluctuations between
the U.S. dollar and other currencies could have a material impact on our operating results.
We may not have sufficient cash on hand or the ability to raise the funds necessary for cash settlement upon
conversion of our convertible senior notes, to repurchase such notes for cash upon a fundamental change, or
repay the Notes at their maturity, and our future debt may contain limitations on our ability to pay cash upon
conversion or repurchase of such notes.
In 2014, we issued $935.0 million in aggregate principal amount of 0.25% convertible senior notes due 2019, or the
2019 Notes, and $954.0 million in aggregate principal amount of 1.00% convertible senior notes due 2021, or the 2021
Notes, in private placements to qualified institutional buyers. In June 2018, we issued an additional $1.15 billion in
aggregate principal amount of 0.25% convertible senior notes due 2024, which we refer to as the Notes when taken
together with the 2019 Notes and the 2021 Notes, in a private placement to qualified institutional buyers. As of December
31, 2018, we had a total par value of $3.04 billion of outstanding Notes.
Holders of the Notes will have the right under the relevant indenture governing the Notes to require us to repurchase
all or a portion of their Notes upon the occurrence of a fundamental change before the relevant maturity date, in each
case at a repurchase price equal to 100% of the principal amount of the respective services of Notes, plus accrued and
unpaid interest, if any, to the fundamental change repurchase date. In addition, upon conversion of the Notes, unless we
elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering
any fractional shares), we will be required to make cash payments in respect of the Notes being converted. Moreover, we
will be required to repay the Notes in cash at their maturity, unless earlier converted or repurchased. However, we may
not have sufficient available cash on hand or be able to obtain financing at the time we are required to make cash
settlement upon conversion of the Notes, repurchase the Notes upon a fundamental change, or repay the Notes at their
maturity. In addition, our ability to repurchase the Notes or pay cash due upon conversions of the Notes may be limited by
law, regulatory authority or agreements governing our future indebtedness.
Our ability to refinance the Notes, make cash payments in connection with conversions of the Notes, repurchase the
Notes in the event of a fundamental change, or repay the Notes at their maturity will depend on market conditions and our
future performance, which is subject to economic, financial, competitive and other factors beyond our control. We also
may not use the cash we have raised through the issuance of the Notes in an optimally productive and profitable manner.
Since inception we have incurred significant operating losses and we historically had not been cash flow positive and may
not be in the future. As a result, we may not have enough available cash or be able to obtain financing on commercially
reasonable terms or at all, at the time we are required to make repurchases of notes surrendered therefor or pay cash
with respect to notes being converted or at their maturity and our level of indebtedness could adversely affect our future
operations by increasing our vulnerability to adverse changes in general economic and industry conditions and by limiting
or prohibiting our ability to obtain additional financing for future capital expenditures, acquisitions and general corporate
and other purposes. In addition, if we are unable to make cash payments upon conversion of the Notes we would be
required to issue significant amounts of our common stock, which would be dilutive to existing stockholders. If we do not
have sufficient cash to repurchase the Notes following a fundamental change or repay the Notes at their maturity, we
would be in default under the terms of the Notes, which could seriously harm our business. In addition, the terms of the
Notes do not limit the amount of future indebtedness we may incur. If we incur significantly more debt, this could intensify
the risks described above.
37
Our business is subject to the risks of earthquakes, fire, power outages, floods and other catastrophic events,
and to interruption by man-made problems such as terrorism.
A significant natural disaster, such as an earthquake, fire, flood or significant power outage could have a material
adverse impact on our business, operating results, and financial condition. Our headquarters and certain of our co-located
data center facilities are located in the San Francisco Bay Area, a region known for seismic activity. Despite any
precautions we may take, the occurrence of a natural disaster or other unanticipated problems at our data centers could
result in lengthy interruptions in our services. In addition, acts of terrorism and other geo-political unrest could cause
disruptions in our business. All of the aforementioned risks may be further increased if our disaster recovery plans prove
to be inadequate. We have implemented a disaster recovery program, which allows us to move production to a back-up
data center in the event of a catastrophe. Although this program is functional, we do not currently serve network traffic
equally from each data center, so if our primary data center shuts down, there will be a period of time that our products or
services, or certain of our products or services, will remain inaccessible to our users or our users may experience severe
issues accessing our products and services.
We do not carry business interruption insurance sufficient to compensate us for the potentially significant losses,
including the potential harm to our business that may result from interruptions in our ability to provide our products and
services.
We may have exposure to greater than anticipated tax liabilities, which could adversely impact our operating
results.
Our income tax obligations are based in part on our corporate operating structure, including the manner in which we
develop, value and use our intellectual property and the scope of our international operations. The tax laws applicable to
our international business activities, including the laws of the United States and other jurisdictions, are subject to
interpretation. The taxing authorities of the jurisdictions in which we operate may challenge our methodologies for valuing
developed technology (or other intangible assets) or intercompany arrangements, which could increase our worldwide
effective tax rate and harm our financial condition and operating results. On October 5, 2015, the Organization for
Economic Cooperation and Development (OECD), an international association of 34 countries, including the U.S., Ireland,
and UK, released the final reports from its Base Erosion and Profit Shifting (BEPS) Action Plans. The BEPS
recommendations covered a number of issues, including country-by-country reporting, permanent establishment rules,
transfer pricing rules and tax treaties. Future tax reform resulting from this development may result in changes to long-
standing tax principles, which could adversely affect our effective tax rate or result in higher cash tax liabilities. We are
subject to review and audit by U.S. federal and state and foreign tax authorities. Tax authorities may disagree with certain
positions we have taken and any adverse outcome of such a review or audit could have a negative effect on our financial
position and operating results. In addition, our future income taxes could be adversely affected by earnings being lower
than anticipated in jurisdictions that have lower statutory tax rates and higher than anticipated in jurisdictions that have
higher statutory tax rates, by changes in the valuation of our deferred tax assets and liabilities, or by changes in tax laws,
regulations or accounting principles, as well as certain discrete items. Furthermore, changes to the taxation of
undistributed foreign earnings could change our future intentions regarding reinvestment of such earnings. Greater than
anticipated tax expenses, or disputes with tax authorities, could adversely impact our operating results. In addition, many
countries in Europe, as well as a number of other countries and organizations, have recently proposed changes to tax
laws regarding digital services that could significantly increase our tax obligations in many countries where we do
business or require us to change the manner in which we operate our business.
On August 7, 2018, the Ninth Circuit Court of Appeals withdrew its July 24, 2018 opinion in Altera Corp. v.
Commissioner which required related parties in an intercompany cost-sharing arrangement to share expenses related to
share-based compensation and reversed the prior decision of the United States Tax Court. We will continue to monitor the
potential effects of any future developments in this case and related matters. We could be negatively impacted by an
adverse ruling in the case.
38
Uncertainties in the interpretation and application of the 2017 Tax Cuts and Jobs Act could materially affect our
tax obligations and effective tax rate.
The 2017 Tax Cuts and Jobs Act (the “Tax Act”) significantly affected U.S. tax law by changing how U.S. income tax
is assessed on multinational corporations. The Tax Act requires complex computations not previously provided for in U.S.
tax law and the U.S. Department of Treasury has issued and will continue to issue regulations and interpretive guidance
that may significantly impact how we will apply the law and impact our results of operations. As additional regulatory and
interpretive guidance is issued, we may refine our analysis and make adjustments that differ from amounts initially
recorded, which could materially affect our tax obligations and effective tax rate.
If our goodwill or intangible assets become impaired, we may be required to record a significant charge to
earnings.
Under generally accepted accounting principles in the United States, or GAAP, we review our intangible assets for
impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill is
required to be tested for impairment at least annually. As of December 31, 2018, we had recorded a total of $1.27 billion
of goodwill and intangible assets. An adverse change in market conditions or financial results, particularly if such change
has the effect of changing one of our critical assumptions or estimates, could result in a change to the estimation of fair
value that could result in an impairment charge to our goodwill or intangible assets. Any such material charges may have
a material negative impact on our operating results.
Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.
As of December 31, 2018, we had U.S. federal net operating loss carryforwards of approximately $2.85 billion and
state net operating loss carryforwards of approximately $1.30 billion. As of December 31, 2018, we had federal R&D
credits of $300.4 million and state credits of $236.2 million. Under Sections 382 and 383 of the Internal Revenue Code of
1986, as amended, or the Code, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-
change net operating loss carryforwards and other pre-change tax attributes, such as research tax credits, to offset its
post-change income and taxes may be limited. In general, an “ownership change” occurs if there is a cumulative change
in our ownership by “5% shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules
may apply under state tax laws. In the event that it is determined that we have in the past experienced an ownership
change, or if we experience one or more ownership changes as a result of future transactions in our stock, then we may
be limited in our ability to use our net operating loss carryforwards and other tax assets to reduce taxes owed on the net
taxable income that we earn. Any such limitations on the ability to use our net operating loss carryforwards and other tax
assets could adversely impact our business, financial condition and operating results.
39
We may require additional capital to support our operations or the growth of our business, and we cannot be
certain that this capital will be available on reasonable terms when required, or at all.
From time to time, we may need additional financing to operate or grow our business. Our ability to obtain additional
financing, if and when required, will depend on investor and lender demand, our operating performance, the condition of
the capital markets and other factors, and we cannot assure you that additional financing will be available to us on
favorable terms when required, or at all. If we raise additional funds through the issuance of equity, equity-linked or debt
securities, those securities may have rights, preferences or privileges senior to the rights of our common stock, and our
existing stockholders may experience dilution. If we are unable to obtain adequate financing or financing on terms
satisfactory to us when we require it, our ability to continue to support the operation or growth of our business could be
significantly impaired and our operating results may be harmed.
Risks Related to Ownership of Our Common Stock
Anti-takeover provisions contained in our amended and restated certificate of incorporation and amended and
restated bylaws, as well as provisions of Delaware law, could impair a takeover attempt.
Our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law contain
provisions which could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed
undesirable by our board of directors. Among other things, our amended and restated certificate of incorporation and
amended and restated bylaws include provisions:
•
•
•
•
•
•
creating a classified board of directors whose members serve staggered three-year terms;
authorizing “blank check” preferred stock, which could be issued by our board of directors without stockholder
approval and may contain voting, liquidation, dividend and other rights superior to our common stock;
limiting the liability of, and providing indemnification to, our directors and officers;
limiting the ability of our stockholders to call and bring business before special meetings;
requiring advance notice of stockholder proposals for business to be conducted at meetings of our
stockholders and for nominations of candidates for election to our board of directors; and
controlling the procedures for the conduct and scheduling of stockholder meetings.
These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in
our management.
As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the Delaware
General Corporation law, which prevents certain stockholders holding more than 15% of our outstanding common stock
from engaging in certain business combinations without approval of the holders of at least two-thirds of our outstanding
common stock not held by such 15% or greater stockholder.
Any provision of our amended and restated certificate of incorporation, amended and restated bylaws or Delaware
law that has the effect of delaying, preventing or deterring a change in control could limit the opportunity for our
stockholders to receive a premium for their shares of our common stock, and could also affect the price that some
investors are willing to pay for our common stock.
The market price of our common stock has been and will likely continue to be volatile, and you could lose all or
part of your investment.
The market price of our common stock has been and may continue to be highly volatile in response to various
factors, some of which are beyond our control. From January 1, 2017 to December 31, 2018, the reported high and low
sales prices of our common stock has ranged from $47.79 to $14.12. In addition to the factors discussed in this “Risk
Factors” section and elsewhere in this Annual Report on Form 10-K, factors that could cause fluctuations in the market
price of our common stock include the following:
•
•
price and volume fluctuations in the overall stock market from time to time;
volatility in the market prices and trading volumes of technology stocks;
40
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
changes in operating performance and stock market valuations of other technology companies generally, or
those in our industry in particular;
sales of shares of our common stock by us or our stockholders;
rumors and market speculation involving us or other companies in our industry;
failure of securities analysts to maintain coverage of us, changes in financial estimates by securities analysts
who follow our company, or our failure to meet these estimates or the expectations of investors;
the financial or non-financial metric projections we may provide to the public, any changes in those projections
or our failure to meet those projections;
announcements by us or our competitors of new products or services;
the public’s reaction to our press releases, other public announcements and filings with the SEC;
actual or anticipated changes in our operating results or fluctuations in our operating results;
actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape
generally;
our issuance of shares of our common stock, whether in connection with an acquisition or upon conversion of
some or all of our outstanding Notes;
litigation or regulatory action involving us, our industry or both, or investigations by regulators into our
operations or those of our competitors;
developments or disputes concerning our intellectual property or other proprietary rights;
announced or completed acquisitions of businesses or technologies by us or our competitors;
new laws or regulations or new interpretations of existing laws or regulations applicable to our business;
changes in accounting standards, policies, guidelines, interpretations or principles;
any significant change in our management; and
general economic conditions and slow or negative growth of our markets.
In addition, in the past, following periods of volatility in the overall market and the market price of a particular
company’s securities, securities class action litigation has often been instituted against these companies. Any securities
litigation can result in substantial costs and a diversion of our management’s attention and resources. We are currently
subject to securities litigation and may experience more such litigation following any future periods of volatility.
The note hedge and warrant transactions may affect the value of our common stock.
Concurrent with the issuance of the Notes, we entered into note hedge transactions with certain financial institutions,
which we refer to as the option counterparties. The note hedge transactions are generally expected to reduce the potential
dilution upon any conversion of the Notes and/or offset any cash payments we are required to make in excess of the
principal amount of converted Notes, as the case may be. We also entered into warrant transactions with the option
counterparties. However, the warrant transactions could separately have a dilutive effect to the extent that the market
price of our common stock exceeds the applicable strike price of the warrants.
The option counterparties or their respective affiliates may modify their initial hedge positions by entering into or
unwinding various derivatives contracts with respect to our common stock and/or purchasing or selling our common stock
or other securities of ours in secondary market transactions prior to the maturity of the Notes (and are likely to do so
during any observation period related to a conversion of Notes or following any repurchase of Notes by us on any
fundamental change repurchase date or otherwise). This activity could cause or avoid an increase or a decrease in the
market price of our common stock.
In addition, if any such convertible note hedge and warrant transactions fail to become effective, the option
counterparties or their respective affiliates may unwind their hedge positions with respect to our common stock, which
could adversely affect the value of our common stock.
41
If securities or industry analysts cease publishing research or reports about us, our business or our market, or if
they change their recommendations regarding our common stock adversely, the price of our common stock and
trading volume could decline.
The trading market for our common stock is influenced, to some extent, by the research and reports that securities
or industry analysts publish about us, our business, our industry, our market or our competitors. If any of the analysts who
cover us change their recommendation regarding our common stock adversely, or provide more favorable relative
recommendations about our competitors, the price of our common stock would likely decline. If any analysts who cover us
were to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial
markets, which in turn could cause the price of our common stock or trading volume to decline.
We do not expect to declare any dividends in the foreseeable future.
We do not anticipate declaring any cash dividends to holders of our common stock in the foreseeable future. In
addition, our credit facility contains restrictions on payments including payments of cash dividends. Consequently,
investors may need to rely on sales of our common stock after price appreciation, which may never occur, as the only way
to realize any future gains on their investment.
Item 1B. UNRESOLVED STAFF COMMENTS
None.
Item 2. PROPERTIES
Facilities
As of December 31, 2018, we leased office facilities around the world totaling approximately 1,561,000 square feet,
including approximately 749,000 square feet for our corporate headquarters in San Francisco, California. We also lease
data center facilities in the United States pursuant to various lease agreements and co-location arrangements with data
center operators. We believe our facilities are sufficient for our current needs.
Item 3. LEGAL PROCEEDINGS
Legal Proceedings
Beginning in September 2016, multiple putative class actions and derivative actions were filed in state and federal
courts in the United States against Twitter, Twitter’s directors, and/or certain former officers alleging false and misleading
statements in violation of securities laws and breach of fiduciary duty. The putative class actions were consolidated in the
U.S. District Court for the Northern District of California. On October 16, 2017, the court granted in part and denied in part
the Company’s motion to dismiss. On July 17, 2018, the court granted plaintiffs' motion for class certification in the
consolidated securities action. The Company disputes the claims and continues to defend the lawsuits vigorously.
We are also currently involved in, and may in the future be involved in, legal proceedings, claims, investigations, and
government inquiries arising in the ordinary course of business. These proceedings, which include both individual and
class action litigation and administrative proceedings, have included, but are not limited to matters involving content on
the platform, intellectual property, privacy, securities, employment and contractual rights. Legal risk may be enhanced in
jurisdictions outside the United States where our protection from liability for content published on our platform by third
parties may be unclear and where we may be less protected under local laws than we are in the United States. Future
litigation may be necessary, among other things, to defend ourselves, and our users or to establish our rights.
Although the results of the legal proceedings, claims, investigations, and government inquiries in which we are
involved cannot be predicted with certainty, we do not believe that there is a reasonable possibility that the final outcome
of these matters will have a material adverse effect on our business, financial condition, operating results, or prospects.
However, the final results of any current or future proceeding cannot be predicted with certainty, and until there is final
resolution on any such matter that we may be required to accrue for, we may be exposed to loss in excess of the amount
accrued. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement
costs, diversion of management resources, and other factors.

PART II
Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY RELATED STOCKHOLDER MATTERS AND ISSUER
PURCHASES OF EQUITY SECURITIES
Market Information for Common Stock
Our common stock has been listed on the New York Stock Exchange under the symbol “TWTR” since November 7,
2013. Prior to that date, there was no public trading market for our common stock.
Holders of Record
As of February 7, 2019, there were 876 holders of record of our common stock. Because many of our shares of
common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total
number of stockholders represented by these record holders.
Dividend Policy
We have never declared or paid any cash dividends on our capital stock. We intend to retain any future earnings
and do not expect to pay any dividends in the foreseeable future. Any future determination to declare cash dividends will
be made at the discretion of our board of directors, subject to applicable laws, and will depend on a number of factors,
including our financial condition, results of operations, capital requirements, contractual restrictions, general business
conditions and other factors that our board of directors may deem relevant. In addition, the credit facility contains
restrictions on payments including cash payments of dividends.
Unregistered Sales of Equity Securities
During 2018, we issued a total of 773,950 shares of our common stock in connection with the acquisition of one
company.
The foregoing transaction did not involve any underwriters, any underwriting discounts or commissions, or any public
offering. We believe the offers, sales, and issuances of the above securities were exempt from registration under the
Securities Act of 1933, as amended (the “Act”) by virtue of Section 4(a)(2) of the Act, because the issuance of securities
to the recipients did not involve a public offering. The recipients of the securities in this transaction represented their
intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution
thereof, and appropriate legends were placed upon the stock certificates issued in these transactions. All recipients had
adequate access, through their relationships with us or otherwise, to information about us. The issuances of these
securities were made without any general solicitation or advertising.
Performance Graph
This performance graph shall not be deemed “soliciting material” or to be “filed” with the SEC for purposes of
Section 18 of the Securities Exchange Act of 1934, as amended (Exchange Act), or otherwise subject to the liabilities
under that Section, and shall not be deemed to be incorporated by reference into any filing of Twitter, Inc. under the
Securities Act of 1933, as amended, or the Exchange Act.

The following graph compares the cumulative total return to stockholders on our common stock relative to the
cumulative total returns of the Standard & Poor’s 500 Index, or S&P 500, and the Dow Jones Internet Composite Index, or
DJ Internet Composite. An investment of $100 (with reinvestment of all dividends) is assumed to have been made in our
common stock and in each index on November 7, 2013, the date our common stock began trading on the NYSE, and its
relative performance is tracked through December 31, 2018. The returns shown are based on historical results and are
not intended to suggest future performance.

Non-GAAP Financial Measures
To supplement our consolidated financial statements presented in accordance with generally accepted accounting
principles in the United States, or GAAP, we consider certain financial measures that are not prepared in accordance with
GAAP, including Adjusted EBITDA, non-GAAP income before income taxes, non-GAAP provision for income taxes as it
relates to the calculation of non-GAAP net income, and non-GAAP net income. These non-GAAP financial measures are
not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similarly-titled
measures presented by other companies.

Adjusted EBITDA
We define Adjusted EBITDA as net income (loss) adjusted to exclude stock-based compensation expense,
depreciation and amortization expense, interest and other expenses, net, provision (benefit) for income taxes,
restructuring charges and one-time nonrecurring gain, if any.

Non-GAAP Net Income
We define non-GAAP net income as net income (loss) adjusted to exclude stock-based compensation expense,
amortization of acquired intangible assets, non-cash interest expense related to convertible notes, non-cash expense
related to acquisitions, impairment of investments in privately-held companies, restructuring charges and one-time
nonrecurring gain, and adjustment to income tax expense based on the non-GAAP measure of profitability using our
blended U.S. statutory tax rate, which was 24% for 2018 as a result of the Tax Act and 37% for all other historical periods
presented.
Non-GAAP Income before Income Taxes. We define non-GAAP income before income taxes as income (loss)
before income taxes adjusted to exclude stock-based compensation expense, amortization of acquired intangible assets,
non-cash interest expense related to convertible notes, non-cash expense related to acquisitions, impairment of
investments in privately-held companies, and restructuring charges and one-time nonrecurring gain.
Non-GAAP Provision for Income Taxes. We define non-GAAP provision for income taxes as the current and
deferred income tax expense commensurate with the non-GAAP measure of profitability using our blended U.S. statutory
tax rate.

We use non-GAAP financial measures of Adjusted EBITDA, non-GAAP income before income taxes, non-GAAP
provision for income taxes, and non-GAAP net income in evaluating our operating results and for financial and operational
decision-making purposes. We believe that Adjusted EBITDA, non-GAAP income before income taxes and non-GAAP net
income help identify underlying trends in our business that could otherwise be masked by the effect of the expenses that
we exclude in Adjusted EBITDA, non-GAAP income before income taxes and non-GAAP net income. We believe that
Adjusted EBITDA, non-GAAP income before income taxes and non-GAAP net income provide useful information about
our operating results, enhance the overall understanding of our past performance and future prospects and allow for
greater transparency with respect to key metrics used by our management in its financial and operational decision-
making. We also use these measures to establish budgets and operational goals for managing our business and
evaluating our performance.
49
These non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial
information prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP
financial measures rather than net income (loss), which is the nearest GAAP equivalent of these financial measures.
Some of these limitations are:
•
•
•
•
•
•
Adjusted EBITDA, non-GAAP income before income taxes, non-GAAP provision for income taxes as it relates
to the calculation of non-GAAP net income and non-GAAP net income exclude restructuring charges, one-time
nonrecurring gain and certain recurring non-cash charges, such as stock-based compensation expense,
amortization of acquired intangible assets, non-cash interest expense related to convertible notes and
impairment of investments in privately-held companies;
Stock-based compensation expense has been, and will continue to be for the foreseeable future, a significant
recurring expense in our business and an important part of our compensation strategy;
Adjusted EBITDA and non-GAAP income before income taxes do not reflect tax payments that reduce cash
available to us;
Non-GAAP net income reflects an estimate of taxes calculated in accordance with the SEC’s Non-GAAP
Financial Measures Compliance and Disclosure Interpretation, not actual taxes due or payable;
Adjusted EBITDA excludes depreciation and amortization expense and although these are non-cash charges,
the property and equipment being depreciated and amortized may have to be replaced in the future; and
The expenses that we exclude in our calculation of these non-GAAP financial measures may differ from the
expenses, if any, that our peer companies may exclude from similarly-titled non-GAAP measures when they
report their results of operations.

51
Key Metrics
We review a number of metrics, including the following key metrics, to evaluate our business, measure our
performance, identify trends affecting our business, formulate business plans and make strategic decisions. We believe
that mDAU, and its related growth, are the best ways to measure our success against our objectives and to show the size
of our audience and engagement going forward, so we will discontinue disclosing MAU after the first quarter of 2019.
Monetizable Daily Active Usage (monetizable DAU or mDAU). We define monetizable daily active usage or users
(mDAU) as Twitter users who logged in and accessed Twitter on any given day through a client capable of displaying ads
(e.g., Twitter.com or the Twitter App). Our definition and calculation of mDAU is the same as that of the DAU data
presented since the first quarter of 2016. Additionally, our calculation of mDAU is not based on any standardized industry
methodology and is not necessarily calculated in the same manner or comparable to similarly-titled measures presented
by other companies. Average mDAU for a period represents the number of mDAU on each day of such period divided by
the number of days for such period. Changes in mDAU are a measure of changes in the size of our daily logged in active
user base. To calculate the year-over-year change in mDAU, we subtract the average mDAU for the three months ended
in the previous year from the average mDAU for the same three months ended in the current year and divide the result by
the average mDAU for the three months ended in the previous year.
In the three months ended December 31, 2018, we had 126 million average mDAUs, which represents an increase
of 9% from the three months ended December 31, 2017. The increase was driven by a combination of organic growth,
marketing, and product improvements. In the three months ended December 31, 2018, we had 27 million average mDAUs
in the United States and 99 million average mDAUs in the rest of the world, which represent increases of 5% and 11%,
respectively, from the three months ended December 31, 2017.
For additional information on how we calculate changes in mDAUs and factors that can affect this metric, see the
section titled “Note Regarding Key Metrics.”
52
Monthly Active Users (MAUs). We define MAUs as Twitter users who logged in or were otherwise authenticated and
accessed Twitter through our website, mobile website, desktop or mobile applications, SMS or registered third-party
applications or websites in the 30-day period ending on the date of measurement. Average MAUs for a period represent
the average of the MAUs at the end of each month during the period. MAUs are a measure of the size of our logged in or
otherwise authenticated active user base. In the three months ended December 31, 2018, we had 321 million average
MAUs, which represents a decrease of 3% from the three months ended December 31, 2017. MAU growth is historically
seasonally weak in the fourth quarter. The decrease in average MAUs was driven by a number of factors, including
product changes that reduced the number of email notifications sent, as well as decisions we have made to prioritize the
health of the service and not to move to paid SMS carrier relationships in certain markets, and, to a lesser extent,
changes we made to comply with the General Data Protection Regulation (GDPR). In the three months ended
December 31, 2018, we had 66 million average MAUs in the United States and 255 million average MAUs in the rest of
the world, which each represent decreases of 3%, from the three months ended December 31, 2017. For additional
information on how we calculate MAUs and factors that can affect this metric, see the section titled “Note Regarding Key
Metrics.” As we announced on February 7, 2019, mDAU will be the metric we use to show the size of our audience and
engagement going forward, so we will discontinue disclosing MAU after the first quarter of 2019.
(1) Reported average Monthly Active Users reflects adjustments for approximately 1-2 million users per quarter of certain third-party applications that
were included as Twitter MAUs that should not have been considered MAUs in certain prior periods. Daily Active Usage was not affected. Further details
regarding the adjustment can be found in the section titled "Note About Our MAU Adjustment."
(2) In the three months ended March 31, 2018, we discovered that a software change made in the second quarter of 2017 resulted in a non-material
overstatement of our historical MAU in 2017. The differences were between 30,000 and 400,000 in each period presented for total MAU. After rounding,
the only impact to our prior disclosures was to reduce international MAU from 261 million to 260 million in the third quarter of 2017 due to a change of
approximately 175,000 international MAUs.
53
Changes in Ad Engagements and Cost per Ad Engagement. We define an ad engagement as a user interaction
with one of our pay-for-performance advertising products. Ad engagements with our advertising products are based on a
user completing an objective set out by an advertiser such as expanding, Retweeting, liking or replying to a Promoted
Tweet, viewing an embedded video, downloading or engaging with a promoted mobile application, clicking on a website
link, signing up for marketing emails from advertisers, following the account that tweets a Promoted Tweet, or completing
a transaction on an external website. We believe changes in ad engagements is one way to measure user engagement
with our advertising products. We believe changes in cost per ad engagement is one way to measure demand.
In the three months ended December 31, 2018, ad engagements increased 33% from the three months ended
December 31, 2017. The increase was driven by increased demand and improved clickthrough rates (CTR), which grew
on a year-over-year basis across the majority of ad types as our ad prediction models and video ad product performance
continues to improve. In the three months ended December 31, 2018, cost per ad engagement decreased 7% from the
three months ended December 31, 2017. The decrease in cost per ad engagement reflects higher CTR from improved
relevance, an ongoing shift to video ads, which carry higher CTR and lower CPE, and slight compression in like for like
pricing. With improved CTR, advertisers are able to get the same amount of engagements (or more) at a lower (or similar)
price.
Factors Affecting Our Future Performance
User Growth and Monetization. User growth trends reflected in the growth rate of mDAUs and monetization trends
reflected in advertising engagements are key factors that affect our revenue. As our user base and the level of
engagement of our users grow, we believe the potential to increase our revenue grows.
User Growth. We have generally experienced growth in our number of mDAU over the last several years. In general,
a higher proportion of Internet users in the United States and Japan use Twitter than Internet users in other countries.
Accordingly, in the future we expect our user growth rate in certain international markets to continue to be higher than our
user growth rate in the United States. However, we expect to face challenges in entering some markets, such as China,
where access to Twitter is blocked, as well as certain other countries that have intermittently restricted access to Twitter.
Restrictions or limitations on access to Twitter may adversely impact our ability to increase the size of our user base and
generate additional revenue in certain markets.
We intend to grow mDAU by building and shipping product changes more rapidly to make Twitter safer and investing
in our core use case and in new product areas that further strengthen our unique position as the best and fastest place to
see and talk about what’s happening in the world. Our mDAU growth rate has fluctuated over time, and it may slow or
decline. To the extent our mDAU growth or growth rate slows or the absolute number of mDAU declines, our revenue
growth will become dependent on our ability to increase levels of user engagement on Twitter and increasing revenue
growth from third-party publishers’ websites and applications, data licensing and other offerings.
54
Monetization. There are many variables that impact the monetization of our platform, such as the number of users,
our users’ level of engagement with our platform, ad load (which is a function of the amount of advertising we choose to
display), our users’ engagement with our Promoted Products, advertiser demand and cost per ad engagement. Generally,
we design our algorithms for our pay-for-performance Promoted Products on Twitter to optimize the overall user
experience and the value we deliver to advertisers. Advertising revenue growth may be impacted by escalating
competition for digital ad spending and the reevaluation of our revenue product feature portfolio, which could result in the
de-emphasis of certain product features. Furthermore, we may see a decline in the number of advertisers on a year-over-
year basis, which may also impact overall demand for our ads products. We have, and may in the future, increase ad load
to the extent that we are able to continue to reach the right balance of advertiser value and the overall user experience. In
order to improve monetization, we plan to increase the value of our advertising services by continuing to increase the size
and engagement of our user base as well as improve our ability to target advertising to our users’ interests and the ability
of our advertisers to optimize their campaigns and measure the results of their campaigns.
Although the majority of the Promoted Products we sell to our advertisers are placed on Twitter, we have augmented
our advertising revenue by selling products that we place on third-party publishers’ websites, applications or other
offerings. When we place ads off our owned and operated properties, we incur additional costs, particularly traffic
acquisition costs, to fulfill our services to advertisers.
We intend to continue to increase the monetization of our platform by improving the targeting capabilities of our
advertising services to enhance the value of our Promoted Products for advertisers, delivering differentiated products to
advertisers, and developing new ad formats for advertisers.
Effectiveness of Our Advertising Services. Advertisers can use Twitter to communicate directly with their followers
for free, but many choose to purchase our advertising services to reach a broader audience and further promote their
brands, products and services. We believe that increasing the effectiveness of our Promoted Products for advertisers, as
well as providing better measurement tools and improving creative capabilities, will increase the amount that advertisers
spend with us. We aim to increase the value of our Promoted Products by increasing the size and engagement of our user
base, improving our ability to target advertising to our users’ interests and improving the ability of our advertisers to
optimize their campaigns and measure the results of their campaigns. We may also develop new advertising products and
services.
Investment in International Operations. We intend to strategically invest in our international operations in order to
expand our user base and advertiser base and increase user engagement and monetization internationally. In the three
months ended December 31, 2018, we had 99 million average mDAUs internationally compared to 27 million average
mDAUs in the United States. In the three months ended December 31, 2018, we had 255 million average MAUs
internationally compared to 66 million average MAUs in the United States. International growth of mDAUs has been faster
than growth in the United States; however, we derive approximately half of our advertising revenue from advertisers in the
United States.
We face challenges in increasing our advertising revenue internationally, including local competition, differences in
advertiser demand, differences in the digital advertising market and conventions, and differences in the manner in which
Twitter is accessed and used internationally. We face competition from well-established competitors in certain
international markets. In addition, certain international markets are not as familiar with digital advertising in general, or
with new forms of digital advertising, such as our Promoted Products. In these jurisdictions we are investing to educate
advertisers about the benefits of our advertising services. However, we expect that it may require a significant investment
of time and resources to educate advertisers in many international markets. We also face challenges in providing certain
advertising products, features or analytics in certain international markets, such as the European Union, due to
government regulation.
55
Competition. We face competition for users and advertisers. We compete against many companies to attract and
engage users and for advertiser spend, including companies with greater financial resources and substantially larger user
bases which offer a variety of Internet and mobile device-based products, services and content. In recent years there has
been a significant number of acquisitions and consolidation activity by and among our actual and potential competitors.
We must compete effectively for users and advertisers in order to grow our business and increase our revenue. We
believe that our ability to compete effectively for users depends upon a number of factors, including the quality of our
products and services and the actual or perceived return our advertisers receive on their investment in our products and
services. Our ability to compete effectively for advertisers also depends upon a number of factors, including our ability to
offer attractive advertising products with unique targeting capabilities, the size of our active user base, and our ability to
have the most valuable audience when they are most receptive. We have seen competition for digital ad spending and
expect this trend to continue. In addition, many advertisers, particularly branded advertisers use marketing mix analyses
to determine how to allocate their advertising budgets on an annual or bi-annual basis. As a result, we need to
demonstrate to those advertisers during the appropriate time period that we provide a better return on investment than our
competitors do in order to secure, increase or sustain our share of the advertising budget allocated for a significant portion
of the year until the next budget cycle. We intend to continue to invest in research and development to improve our
products and services for users and advertisers and to grow our active user base in order to address the competitive
challenges in our industry. As part of our strategy to improve our products and services, we may acquire other companies
to add engineering talent or complementary products and technologies.
Investment in Infrastructure. We strive to optimize the capacity and enhance the capability and reliability of our
infrastructure. Our infrastructure is critical to providing users, platform partners, advertisers and data partners access to
our platform, particularly during major planned and unplanned events, such as elections, sporting events or natural
disasters, when activity on our platform increases dramatically. As our user base and the activity on our platform grow, we
expect that investments and expenses associated with our infrastructure will continue to grow. These investments and
expenses include the expansion and improvement of our data center operations and related operating costs, additional
servers and networking equipment to increase the capacity of our infrastructure, increased bandwidth costs, and costs to
secure our customers’ data.
Products and Services Innovation. Our ability to increase the size and engagement of our user base, attract
advertisers and increase our revenue will depend, in part, on our ability to improve existing products and services and to
successfully develop or acquire new products and services. We will continue to invest in revenue products as we work to
improve our ads platform and ad formats to help our ad partners launch new products and services and connect with
what’s happening on Twitter. We plan to continue to make significant investments in research and development and, from
time to time, we may acquire companies to enhance our products, services and technical capabilities. In addition, we
continue to invest in health as we continue our work to help people find credible information on our service and feel safe
participating in the conversation on Twitter.
Investment in Talent. We intend to invest in hiring key engineering roles and retaining talented employees to grow
our business. We have seen reduced levels of attrition in 2018, but we need to continue to focus on hiring and employee
retention to be successful. We have also made, and intend to continue to make, acquisitions that add engineers,
designers, product managers and other personnel with specific technology expertise. In addition, we must retain our high-
performing personnel in order to continue to develop, sell and market our products and services and manage our
business.
Seasonality. Advertising spending is traditionally strongest in the fourth quarter of each year. Historically, this
seasonality in advertising spending has affected our quarterly results, with higher sequential advertising revenue growth
from the third quarter to the fourth quarter compared to sequential advertising revenue growth from the fourth quarter to
the subsequent first quarter. For example, our advertising revenue increased 17%, 28% and 22% between the third and
fourth quarters of 2016, 2017 and 2018, respectively, while advertising revenue for the first quarter of 2017 and 2018
decreased 26% and 11% compared to the fourth quarter of 2016 and 2017, respectively.
56
Stock-Based Compensation Expense. We have historically utilized, and intend to continue to utilize, various forms of
stock-based awards in order to hire and retain talented employees. During the years ended December 31, 2018 and
2017, we recognized $326.2 million and $433.8 million of expense related to stock-based compensation, respectively. As
of December 31, 2018, we had unrecognized stock-based compensation expense of approximately $715.0 million related
to outstanding equity awards, which we expect to recognize over a weighted-average period of approximately three years.
The stock-based compensation expenses related to our outstanding equity awards have a significant impact on the
amount of net income we generate on a GAAP basis. We made significant progress in reducing our annual stock-based
compensation expense on both an absolute basis and as a percentage of revenue, down to 11% in 2018, from 18% and
24% in 2017 and 2016, respectively. We remain committed to maintaining stock-based compensation as a percentage of
revenue in line with our peers.

Revenue
We generate the substantial majority of our revenue from the sale of advertising services. We also generate revenue
by licensing our data to third parties and providing mobile advertising exchange services.
Advertising Services
We generate most of our advertising revenue by selling our Promoted Products. Currently, our Promoted Products
consist of the following:
•
•
•
Promoted Tweets. Promoted Tweets, which are labeled as “promoted,” appear within a user’s timeline, search
results or profile pages just like an ordinary Tweet regardless of device, whether it be desktop or mobile. Using
our proprietary algorithms and understanding of the interests of each user, we can deliver Promoted Tweets
that are intended to be relevant to a particular user. We enable our advertisers to target an audience based on
our users’ interest graphs. Our Promoted Tweets are pay-for-performance or pay-for-impression delivered
advertising that are priced through an auction. Our Promoted Tweets include objective-based features that
allow advertisers to pay only for the types of engagement selected by the advertisers, such as Tweet
engagements (e.g., Retweets, replies and likes), website clicks or conversions, mobile application installs or
engagements, obtaining new followers, or video views.
Promoted Accounts. Promoted Accounts, which are labeled as “promoted,” provide a way for our advertisers
to grow a community of users who are interested in their business, products or services. Our Promoted
Accounts are pay-for-performance advertising that is priced through an auction.
Promoted Trends. Promoted Trends, which are labeled as “promoted,” appear at the top of the list of trending
topics or timeline for an entire day in a particular country or on a global basis. We sell our Promoted Trends on
a fixed-fee-per-day basis.
While the majority of the Promoted Products we sell to our advertisers are placed on Twitter, we also generate
advertising revenue by placing advertising products that we sell to advertisers on third-party publishers’ websites,
applications or other offerings.
58
Data Licensing and Other
We generate data licensing and other revenue by (i) offering data products and data licenses that allow our data
partners to access, search and analyze historical and real-time data on our platform, which data consists of public Tweets
and their content, and (ii) providing mobile advertising exchange services through our MoPub exchange. Our data
partners generally purchase licenses to access all or a portion of our data for a fixed period. We recognize data licensing
revenue as our data partners consume and benefit from their continuous use of the licensed data over time. In addition,
we operate a mobile ad exchange and receive service fees from transactions completed on the exchange. Our mobile ad
exchange enables buyers and sellers to purchase and sell advertising inventory and matches buyers and sellers. We
have determined we are not the principal as it relates to our performance obligation of providing an ad exchange service
in the purchase and sale of advertising inventory in transactions between third-party buyers and sellers on the exchange.
Therefore we report revenue related to our ad exchange services on a net basis.

2018 Compared to 2017. Revenue in 2018 increased by $599.1 million compared to 2017.
In 2018, advertising revenue increased by 24% compared to 2017. The substantial majority of our advertising
revenue was generated from our owned and operated platform. Advertising revenue generated from the sale of our
advertising products on our owned and operated platform in 2018 was $2.46 billion as compared to $1.90 billion in 2017.
Advertising revenue generated from the sale of our advertising products placed on third-party publishers’ websites,
applications and other offerings in 2018 was $154.4 million as compared to $211.2 million in 2017.
The overall increase in advertising revenue was primarily attributable to a 55% increase in the number of ad
engagements offset by a 20% decrease in cost per ad engagement in 2018 compared to 2017. The increase in ad
engagements was driven by increased demand and improved clickthrough rates. The decrease in cost per ad
engagement reflects the ongoing mix shift to video ad engagements (which have overall lower cost per ad engagement
compared to other ad formats), higher clickthrough rates, and a slight compression in like for like pricing.
The decrease in advertising revenue from the sale of our advertising products placed on third-party publishers’
websites, applications and other offerings in 2018 was driven primarily by the lack of contribution from TellApart (which
was deprecated in 2017). TellApart revenue contributed $44.6 million in revenue in 2017, mainly in the first half of 2017,
and was fully deprecated in the fourth quarter of 2017.
Advertising revenue continued to be driven by continued sales momentum with advertisers, built around our
differentiated ad formats, better relevance, and improved ROI. As our user base and the level of engagement of our users
grow, we believe the potential to increase our revenue grows.
In 2018, data licensing and other revenue increased by 27% compared to 2017. A majority of the increase was
attributable to expanded and new partnerships.
Looking ahead, while data licensing and other revenue continues to benefit from customers developing new use
cases and smaller customers adopting self-service APIs, we are now largely through our multi-year enterprise renewal
cycle. As a result, with many of our largest partners now at market pricing, revenue growth is likely to moderate in 2019.
59
2017 Compared to 2016. Revenue in 2017 decreased by $86.3 million compared to 2016.
In 2017, advertising revenue decreased by 6% compared to 2016. The substantial majority of our advertising
revenue was generated from our owned and operated platform. Advertising revenue generated from the sale of our
advertising products on our owned and operated platform in 2017 was $1.90 billion as compared to $1.99 billion in 2016.
Advertising revenue generated from the sale of our advertising products placed on third-party publishers’ websites,
applications and other offerings in 2017 was $211.2 million as compared to $260.2 million in 2016. The decrease in
advertising revenue from the sale of our advertising products placed on third-party publishers’ websites, applications and
other offerings in 2017 was driven by significantly lower contribution from TellApart (which was deprecated in 2017), which
was offset by strong performance from Twitter Audience Platform. TellApart revenue was $44.6 million in 2017, mainly in
the first half of 2017, compared to $126.4 million in 2016.
The overall decrease in advertising revenue was primarily attributable to a 52% decrease in cost per ad
engagement offset by a 96% increase in the number of ad engagements in 2017 compared to 2016. The decrease in cost
per ad engagement reflects a higher mix of video ad engagements (which have overall lower cost per ad engagement
compared to other ad formats) and lower cost per ad engagement across the majority of ad formats compared to the
fourth quarter of 2016. The increase in ad engagements was driven by a continuing mix shift toward video ad impressions
as well as higher clickthrough rates.
Advertising revenue continued to be driven by strong growth in our video ad formats offset by declines in traditional
Promoted Tweet and direct response ad formats.
In 2017, data licensing and other revenue increased by 18% compared to 2016. A majority of the increase was
attributable to growth in data licensing fees from the offering of data products.
Cost of Revenue
Cost of revenue includes infrastructure costs, other direct costs including content costs, amortization of acquired
intangible assets and amortization of capitalized labor costs for internally developed software, allocated facilities costs, as
well as traffic acquisition costs, or TAC. Infrastructure costs consist primarily of data center costs related to our co-located
facilities, which include lease and hosting costs, related support and maintenance costs and energy and bandwidth costs;
as well as depreciation of servers and networking equipment; and personnel-related costs, including salaries, benefits and
stock-based compensation, for our operations teams. TAC consists of costs we incur with third parties in connection with
the sale to advertisers of our advertising products that we place on third-party publishers’ websites, applications or other
offerings collectively resulting from acquisitions, and from our organically-built advertising network, Twitter Audience
Platform. Certain of the elements of our cost of revenue are fixed, and cannot be reduced in the near term.

2018 Compared to 2017. In 2018, cost of revenue increased by $103.8 million compared to 2017. The increase was
attributable to an $89.3 million increase in direct costs, primarily driven by an increase in content costs and a $50.4 million
increase in depreciation and amortization expense primarily related to additional internally developed software, server and
networking equipment. These increases were offset by a $35.3 million decrease in TAC substantially due to the lack of
advertising revenue generated from TellApart (which we deprecated in 2017), and a $0.6 million decrease in other expenses.
2017 Compared to 2016. In 2017, cost of revenue decreased by $71.0 million compared to 2016. The decrease was
attributable to a $48.6 million decrease in restructuring expenses, a $45.3 million decrease in infrastructure costs, a $42.7
million decrease in TAC substantially due to the decrease in advertising revenue generated from TellApart (which we
deprecated in 2017), and a $3.5 million decrease in personnel-related costs. These decreases were offset by a $55.5 million
increase in other direct costs that is primarily driven by an increase in content costs, and a $13.6 million increase in
depreciation and amortization expense primarily related to additional internally developed software, server and networking
equipment.
60
We plan to continue to scale the capacity and enhance the capability and reliability of our infrastructure to support
user growth and increased activity on our platform. We expect that cost of revenue will increase in absolute dollar
amounts and vary as a percentage of revenue.
Research and Development
Research and development expenses consist primarily of personnel-related costs, including salaries, benefits and
stock-based compensation, for our engineers and other employees engaged in the research and development of our
products and services. In addition, research and development expenses include amortization of acquired intangible
assets, allocated facilities costs, and other supporting overhead costs.

2018 Compared to 2017. In 2018, research and development expenses increased by $11.8 million compared to
2017. The increase was attributable to a $15.4 million net increase in allocated facilities costs, other supporting overhead
expenses, and other expenses, and the absence of a $12.1 million one-time nonrecurring gain on sale of assets that
occurred in the year ended December 31, 2017. These increases were offset by a $8.7 million net decrease in personnel-
related costs driven by a decrease in stock-based compensation expense due partially to forfeitures offset in part by an
increase in average employee headcount, and a $7.0 million increase in the capitalization of costs associated with
developing software for internal use.
2017 Compared to 2016. In 2017, research and development expenses decreased by $171.5 million compared to
2016. The decrease was attributable to a $141.6 million decrease in personnel-related costs, mainly driven by a decrease
in stock-based compensation expense, a $25.9 million decrease in restructuring charges net of a one-time nonrecurring
gain on sale of assets in 2017, a $23.7 million decrease in allocated facilities and other supporting overhead expenses
due to a decrease in overall total expenses, a $2.6 million decrease in other expenses, and a $2.5 million decrease in
depreciation and amortization expense, offset by a $24.8 million decrease in the capitalization of costs associated with
developing software for internal use.
We plan to continue to invest in key areas of our business to ensure that we have the right level of engineering,
product management and design personnel and related resources to support our research and development efforts. We
expect that research and development costs will increase in absolute dollar amounts and vary as a percentage of
revenue.
Sales and Marketing
Sales and marketing expenses consist primarily of personnel-related costs, including salaries, commissions, benefits
and stock-based compensation for our employees engaged in sales, sales support, business development and media,
marketing, corporate communications and customer service functions. In addition, marketing and sales-related expenses
also include advertising costs, market research, tradeshows, branding, marketing, public relations costs, amortization of
acquired intangible assets, allocated facilities costs, and other supporting overhead costs.

2018 Compared to 2017. In 2018, sales and marketing expenses increased by $53.9 million compared to 2017. The
increase was attributable to a $36.2 million net increase in allocated facilities costs and other supporting overhead
expenses, a $9.3 million increase in marketing and sales-related expenses, and a $23.9 million net increase in personnel-
related costs driven by an increase in average employee headcount offset in part by a decrease in stock-based
compensation expense. These increases were offset by a $15.5 million decrease in amortization of acquired intangible
assets due to certain intangible assets becoming fully amortized.
2017 Compared to 2016. In 2017, sales and marketing expenses decreased by $240.4 million compared to 2016.
The decrease was attributable to a $116.0 million decrease in personnel-related costs, driven by a decrease in average
employee headcount mainly as a result of our 2016 restructuring plan, a $54.0 million decrease in marketing and sales-
related expenses, a $28.0 million decrease in allocated facilities and other supporting overhead expenses due to a
decrease in overall total expenses, a $27.4 million decrease in restructuring expenses, and a $15.0 million decrease in
amortization of acquired intangible assets.
We continue to evaluate key areas in our business to ensure we have the right level of sales and marketing to
execute on our key priorities and objectives. We expect that sales and marketing costs will increase in absolute dollar
amounts and vary as a percentage of revenue.
General and Administrative
General and administrative expenses consist primarily of personnel-related costs, including salaries, benefits and
stock-based compensation, for our executive, finance, legal, information technology, human resources and other
administrative employees. In addition, general and administrative expenses include fees and costs for professional
services, including consulting, third-party legal and accounting services and facilities costs and other supporting overhead
costs that are not allocated to other departments.

employee headcount offset in part by a decrease in stock-based compensation expense, and a $7.9 million increase in
professional service fees. These increases were offset by a $17.6 million decrease in allocated facilities costs, other
supporting overhead expenses, and other expenses.
2017 Compared to 2016. In 2017, general and administrative expense decreased by $9.4 million compared to 2016.
The decrease was attributable to a $9.2 million decrease in personnel-related costs, mainly driven by a decrease in stock-
based compensation expense, a $4.9 million decrease in facilities and supporting costs, and a $4.8 million decrease in
restructuring charges. The decreases were offset by a $9.0 million increase in fees and costs for professional services,
and a $0.5 million increase in other expenses.
We plan to continue to invest in key areas of our business and ensure that we have the right level of general and
administrative support on our key priorities and objectives. We expect that general and administrative expenses will
increase in absolute dollar amounts and vary as a percentage of revenue.

Interest Expense
Interest expense consists primarily of interest expense incurred in connection with the $935.0 million principal
amount of 0.25% convertible senior notes due 2019, or the 2019 Notes, $954.0 million principal amount of 1.00%
convertible senior notes due 2021, or the 2021 Notes, and the $1.15 billion principal amount of 0.25% convertible senior
notes due 2024, or the 2024 Notes, and together with the 2019 Notes and 2021 Notes, the Notes, and interest expense
related to capital leases and other financing facilities.

issuance of the 2024 Notes in June 2018. Interest expense in 2018 was comprised of $127.7 million of total interest
expense related to the Notes as well as our credit facility (described below) and $4.9 million related to capital leases of

2017 Compared to 2016. In 2017, interest income increased by $20.1 million compared to 2016. The increase was
primarily attributable to higher invested cash balances and higher interest rates.
Other Income (Expense), Net
Other income (expense), net, consists of unrealized foreign exchange gains and losses due to re-measurement of
monetary assets and liabilities denominated in non-functional currencies, realized foreign exchange gains and losses on
foreign exchange transactions, and gains and losses on investments in privately-held companies. We expect our foreign
exchange gains and losses will vary depending upon movements in the underlying exchange rates.

2018 Compared to 2017. In 2018, other expense, net, was $8.4 million compared to other expense, net, of $73.3

2018, compared to a $62.4 million impairment charge in the year ended December 31, 2017, and the more favorable
foreign currency exchange impacts from foreign currency-denominated assets and liabilities as well as derivative financial
instruments.
63
2017 Compared to 2016. In 2017, other expense, net, was $73.3 million compared to other income, net, of $2.1
million in 2016. The change was primarily attributable to the recording of an impairment charge on an investment in a
privately-held company of $62.4 million in 2017 and less favorable foreign currency exchange impacts from foreign
currency-denominated assets and liabilities as well as derivative financial instruments.
Provision (Benefit) for Income Taxes
Our provision (benefit) for income taxes consists of federal and state income taxes in the United States and income
taxes in certain foreign jurisdictions. In addition, the provision is impacted by deferred income taxes and changes in the
related valuation allowance reflecting the net tax effects of temporary differences between the carrying amounts of assets
and liabilities for financial reporting purposes and the amounts used for income tax purposes.
In December 2017, the Tax Act was enacted into law and the new legislation contains several key tax provisions that
affected us, including a reduction of the federal corporate income tax rate to 21% effective January 1, 2018. We are
required to recognize the effect of the tax law changes in the period of enactment, such as re-measuring our U.S. deferred
tax assets and liabilities as well as our valuation allowance against our net U.S. deferred tax assets. Also in December
2017, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the 2017 Tax Cuts
and Jobs Act (SAB 118), which allows us to record provisional amounts during a measurement period not to extend
beyond one year of the enactment date. We completed our accounting for the Tax Act in the fourth quarter of 2018, within
the one-year measurement period from the enactment. Please refer to Note 14 of the Notes to Consolidated Financial
Statements included in Part II, Item 8 of this Annual Report on Form 10-K for further information.

2018 Compared to 2017. Our benefit for income taxes in the twelve months ended December 31, 2018 was $782.1
million, compared to a provision for income taxes of $12.6 million in 2017. Our current provision for income taxes in the
twelve months ended December 31, 2018 was $19.7 million, compared to a current provision of $19.1 million for the
twelve months ended December 31, 2017. Our deferred benefit for income taxes in the twelve months ended December
31, 2018 was $801.7 million, compared to a deferred benefit for income taxes of $6.4 million in the twelve months ended
December 31, 2017. The change is due to the release of our valuation allowance of $845.1 million related to Brazil and
most of the United States federal and all states deferred tax assets with the exception of California and Massachusetts,
offset by our current year income tax expense of $63.0 million, compared to a provision of $12.6 million in 2017. Excluding
the release of our deferred tax asset valuation allowance, the change was primarily due to the increase in pre-tax
profitability offset by an increase to the benefit of share-based compensation.
2017 Compared to 2016. Our provision for income taxes in 2017 decreased by $3.4 million compared to 2016
primarily due to an increase in the income tax benefit arising from intraperiod allocation and partial release of valuation
allowance attributable to the Tax Act related to alternative minimum tax (AMT) credits.
We anticipate that going forward we will have income tax expense, which amounts could be affected by our
jurisdictional mix of profit before taxes, the extent foreign earnings are taxed in the United States through new provisions
under the Tax Act, changes in tax rates and tax regulations, the impact of tax examinations, the impact of business
combinations, tax effects of share based compensation, and changes in the remaining valuation allowances.

Credit Facility
In August 2018, we entered into a revolving credit agreement with certain lenders which provides for a $500.0 million
revolving unsecured credit facility maturing on August 7, 2023. In connection with entering into the $500.0 million credit
facility, we also terminated our $1.0 billion unsecured revolving credit facility. We are obligated to pay interest on loans
under the new credit facility and other customary fees for a credit facility of this size and type, including an upfront fee and
an unused commitment fee. The interest rate for the new credit facility is determined based on calculations using certain
market rates as set forth in the credit agreement. As of December 31, 2018, no amounts had been drawn under the credit
facility.

Our principal sources of liquidity are our cash, cash equivalents, and short-term investments in marketable
securities. Our cash equivalents and marketable securities are invested primarily in short-term fixed income securities,
including government and investment-grade debt securities and money market funds. In June 2018, we also received net
proceeds of approximately $1.14 billion from the issuance of the 2024 Notes, after deducting the debt issuance costs.
Concurrent with the sales of the 2024 Notes, we entered into privately-negotiated convertible note hedge transactions with
respect to our common stock for which we paid approximately $268.0 million and sold warrants for which we received
approximately $186.8 million.
As of December 31, 2018, we had $6.21 billion of cash, cash equivalents and short-term investments in marketable
securities, of which $210.0 million was held by our foreign subsidiaries. During the SAB 118 period related to the Tax Act,
we re-assessed our intentions related to certain of these funds held by our foreign subsidiaries in light of the reduced tax
associated with repatriation. We have determined that we will no longer be indefinitely reinvested related to these funds
and accrued the incremental foreign withholding taxes. In addition, we have a revolving unsecured credit facility available
to borrow up to $500.0 million. We believe that our existing cash, cash equivalents and short-term investment balance,
and our credit facility, together with cash generated from operations will be sufficient to meet our working capital, capital
expenditure requirements for at least the next 12 months, and to repay the $936.2 million of principal and coupon interest
associated with our 2019 Notes due in September 2019.
Operating Activities
Cash provided by operating activities consists of net income (loss) adjusted for certain non-cash items including
depreciation and amortization, stock-based compensation, amortization of discount on our Notes, deferred income taxes,
impairment of investments in privately-held companies, non-cash restructuring charges, as well as the effect of changes in
working capital and other activities. We expect that cash provided by operating activities will fluctuate in future periods as
a result of a number of factors, including fluctuations in our revenue, increases in operating expenses and costs related to
acquisitions. For additional discussion, see Part I, Item 1A,”Risk Factors.”
Cash provided by operating activities in 2018 was $1.34 billion, an increase in cash inflow of $508.5 million
compared to 2017. Cash provided by operating activities was driven by net income of $1.21 billion, as adjusted for the
exclusion of non-cash expenses and other adjustments totaling $44.8 million, of which the most significant items were a
$845.1 million net benefit to tax expense associated with the release of the valuation allowance related to deferred tax
assets, $425.5 million of depreciation and amortization expense, and $326.2 million of stock-based compensation
expense, and the effect of changes in working capital and other carrying balances that resulted in cash inflows of $89.3
million, which was in part driven by a one-time refund of prepaid employment taxes of $147.5 million.
Cash provided by operating activities in 2017 was $831.2 million, an increase in cash inflow of $68.2 million
compared to 2016. Cash provided by operating activities was driven by a net loss of $108.1 million, as adjusted for the
exclusion of non-cash expenses and other adjustments totaling $971.5 million, of which the most significant items were
$433.8 million of stock-based compensation expense, $395.9 million of depreciation and amortization expense and $62.4
million of impairment charges on an investment in a privately-held company, and the effect of changes in working capital
and other carrying balances that resulted in cash outflows of $32.2 million.
Cash provided by operating activities in 2016 was $763.1 million, an increase in cash inflow of $380.0 million
compared to 2015. Cash provided by operating activities was driven by a net loss of $456.9 million, as adjusted for the
exclusion of non-cash expenses and other adjustments totaling $1.14 billion, of which the most significant items were
$615.2 million of stock-based compensation expense, and the effect of changes in working capital and other carrying
balances that resulted in cash outflow of $82.6 million.
67
Investing Activities
Our primary investing activities consist of purchases of property and equipment, particularly purchases of servers
and networking equipment, leasehold improvements for our facilities, purchases and disposal of marketable securities,
strategic investments in privately-held companies, acquisitions of businesses and other activities.
Cash used in investing activities in 2018 was $2.06 billion, an increase in cash outflow of $1.94 billion compared to
2017. The change was primarily due to a $2.65 billion increase in purchases of marketable securities, a $323.2 million
increase in purchases of property and equipment, an absence of $35.0 million in proceeds from sale of long-lived assets,
and a net increase of $33.6 million in cash used in business combinations, offset by a $1.09 billion net increase
in proceeds from sales and maturities of marketable securities, a $2.6 million decrease in expenditures on other investing
activities and a $10.3 million increase in proceeds from sales of property and equipment.
Cash used in investing activities in 2017 was $116.5 million, a decrease in cash outflow of $476.7 million compared
to 2016. The change was primarily due to a $221.4 million decrease in the purchases of marketable securities, a $80.7
million decrease in purchases of investments in privately-held companies, a net $85.1 million decrease in cash used in
business combinations, a $57.9 million decrease in purchases of property and equipment, a $35.0 million increase in
proceeds from sale of long-lived assets, a $2.8 million increase in net proceeds from sales and maturities of marketable
securities, and a $2.8 million increase in proceeds from sales of property and equipment, offset by a $8.9 million increase
in expenditures on other investing activities.
Cash used in investing activities in 2016 was $593.2 million, a decrease in cash outflow of $305.6 million compared
to 2015. The decrease in cash outflow was due to decreased purchases of marketable securities of $774.9 million,
property and equipment of $128.6 million and other investments of $9.9 million, offset by a decrease in sales and
maturities of marketable securities of $503.4 million, an increase in purchase of investments in privately-held companies
of $71.0 million, and an increase in use of cash as acquisition consideration of $33.4 million.
We anticipate making capital expenditures in 2019 of approximately $550 million to $600 million as we continue to
expand our co-located data centers.
Financing Activities
Our primary financing activities consist of issuances of securities, including common stock issued under our
employee stock purchase plan, capital lease financing and stock option exercises by employees and other service
providers.
Cash provided by financing activities in 2018 was $978.1 million, compared to $78.4 million cash used in financing
activities in 2017. The change was due to net proceeds of $1.14 billion from the issuance of convertible notes net of
issuance costs, reduced by the net cash outflow of $81.2 million from the purchase of convertible note hedges and sale of
warrants closed in connection with the issuance of convertible notes, a $12.4 million decrease in payments of capital
lease obligations, and a $5.4 million increase in proceeds from the issuance of shares of stock from the ESPP, offset by a
$10.3 million increase in tax payments related to net share settlements of equity awards and a $6.0 million decrease in
proceeds from option exercises.
Cash used in financing activities in 2017 was $78.4 million, a decrease in cash outflow of $5.6 million compared to
2016. The decrease in cash outflow was due to a $6.4 million decrease in taxes paid related to net share settlement of
equity awards and other activities and a $1.9 million increase in proceeds from option exercises. These decreases were
offset by a $2.2 million increase in payments of capital lease obligations and a $0.5 million decrease in proceeds from the
issuance of shares of stock from ESPP.
Cash used in financing activities in 2016 was $84.0 million, an increase in cash outflow of $21.0 million compared to
2015. The increase in cash outflow was due to a $14.9 million decrease in proceeds from the issuance of shares of stock
from ESPP, a net $13.3 million increase in tax payments related to net share settlements of equity awards and other
activities, and a net $9.8 million decrease in proceeds from option exercises, offset by a reduction in repayments of capital
lease obligations of $17.0 million.

Off Balance Sheet Arrangements
We do not have any off-balance sheet arrangements and did not have any such arrangements in 2018, 2017 or
2016.
Contractual Obligations
Our principal commitments consist of obligations under the Notes (including principal and coupon interest), capital
and operating leases for equipment, office space and co-located data center facilities, as well as non-cancellable
contractual commitments. The following table summarizes our commitments to settle contractual obligations in cash as of
December 31, 2018.

(1) We have entered into several sublease agreements for office space that we are not fully utilizing. Under the
sublease agreements, we will receive approximately $52.5 million in sublease income over the next four years.
(2)
Other contractual commitments are non-cancelable contractual commitments primarily related to our infrastructure
services, bandwidth and other services arrangements.
As of December 31, 2018, we had recorded liabilities of $17.9 million related to uncertain tax positions. Due to
uncertainties in the timing of potential tax audits, the timing of the resolution of these positions is uncertain and we are
unable to make a reasonably reliable estimate of the timing of payments in individual years beyond 12 months. As a
result, this amount is not included in the above table.
Critical Accounting Policies and Estimates
We prepare our consolidated financial statements in accordance with GAAP. In doing so, we have to make
estimates and assumptions that affect our reported amounts of assets, liabilities, revenue and expenses, as well as
related disclosure of contingent assets and liabilities. To the extent that there are material differences between these
estimates and actual results, our financial condition or operating results would be affected. We base our estimates on past
experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these
estimates on an ongoing basis. We refer to accounting estimates of this type as critical accounting policies and estimates,
which we discuss further below.
Revenue Recognition
We generate the substantial majority of our revenue from the sale of advertising services with the balance from data
licensing and other arrangements.
We generate our advertising revenue primarily from the sale of our Promoted Products: (i) Promoted Tweets, (ii)
Promoted Accounts and (iii) Promoted Trends. Promoted Tweets and Promoted Accounts are pay-for-performance
advertising products or pay on impressions delivered, each priced through an auction. Promoted Trends are featured by
geography and offered on a fixed-fee-per-day basis. Advertisers are obligated to pay when a user engages with a
Promoted Tweet, follows a Promoted Account, when an impression is delivered, or when a Promoted Trend is displayed.
These advertising services may be sold in combination as a bundled arrangement or separately on a stand-alone basis.
69
For our Promoted Product arrangements, significant judgments are (i) identifying the performance obligations in the
contract, (ii) determining the basis for allocating contract consideration to performance obligations, (iii) determining
whether we are the principal or the agent in arrangements where another party is involved in providing specified services
to a customer, and (iv) estimating the transaction price to be allocated for contracts with tiered rebate provisions.
We may generate revenue from the sale of certain Promoted Tweets through placement by Twitter of advertiser ads
against third-party publisher content. We will pay the third-party publisher a revenue share fee for our right to monetize
their content. In such transactions, advertisers are contracting to obtain a single integrated advertising service, the
Promoted Tweet combined with the third-party publisher content, and we obtain control of the third-party publisher content
displayed on Twitter that we then combine with the advertiser ads within the Promoted Tweet. Therefore, we report
advertising revenue generated from these transactions on a gross basis and record the related third-party content
monetization fees as cost of revenue.
We also generate advertising revenue by selling services in which we place ads on third-party publishers’ websites,
applications or other offerings. To fulfill these transactions, we purchase advertising inventory from third-party publishers’
websites and applications where we have identified the advertisers’ targeted audience and therefore incur traffic
acquisition costs prior to transferring the advertising service to our customers. At such point, we have the sole ability to
monetize the third-party publishers advertising inventory. In such transactions, we obtain control of a right to a service to
be performed by the third-party publishers, which gives us the ability to direct those publishers to provide the services to
our customers on our behalf. Therefore, we report advertising revenue generated from these transactions on a gross
basis, and we record the related traffic acquisition costs as cost of revenue.
Fees for the advertising services above are recognized in the period when advertising is delivered as evidenced by a
user engaging with a Promoted Tweet or an ad on a third-party publisher website or application in a manner satisfying the
types of engagement selected by the advertisers, such as Tweet engagements (e.g., retweets, replies and likes), website
clicks, mobile application installs or engagements, obtaining new followers, or video views, following a Promoted Account,
delivery of impressions, or through the display of a Promoted Trend on our platform.
We have concluded that our data licensing arrangements, which grant customers a right to Twitter’s intellectual
property (“IP”) for a defined period of time, may contain a single performance obligation satisfied at a point in time
(“Historical IP”) or over time (“Future IP”), or may contain two or more performance obligations satisfied separately at a
point in time (Historical IP) and over time (Future IP). In some of our data licensing arrangements, pricing is a fixed
monthly fee over a specified term. In arrangements with a single performance obligation satisfied over time, data licensing
revenue is recognized on a straight-line basis over the period in which we provide data as the customer consumes and
benefits from the continuous data available on an ongoing basis. In arrangements with at least two performance
obligations, we allocate revenue on a relative basis between the performance obligations based on standalone selling
price (“SSP”) and recognize revenue as the performance obligations are satisfied.
In other data licensing arrangements, we charge customers based on the amount of sales they generate from
downstream customers using Twitter data. Certain of those royalty-based data licensing arrangements are subject to
minimum guarantees. For such arrangements with a minimum guarantee and a single Future IP performance obligation,
we recognize revenue for minimum guarantees on a straight-line basis over the period in which we provide data. For such
arrangements with a minimum guarantee and two or more performance obligations, we allocate revenue on a relative
basis between the performance obligations based on SSP and recognize revenue as the performance obligations are
satisfied. Royalties in excess of minimum guarantees, if any, are recognized as revenue in the period that the related
downstream customer sales using our licensed data occur, and such amounts have been immaterial to date.
For data licensing arrangements involving two or more performance obligations, we use directly observable
standalone transactions to determine SSP of Historical IP. We use standalone transactions and consider all other
reasonably available observable evidence to estimate SSP of Future IP.
Other revenue is primarily generated from service fees from transactions completed on our mobile ad exchange. Our
mobile ad exchange enables buyers and sellers to purchase and sell advertising inventory by matching them in the
exchange. We have determined we are not the principal in the purchase and sale of advertising inventory in transactions
between third-party buyers and sellers on the exchange because we do not obtain control of the advertising inventory. We
report revenue related to our ad exchange services on a net basis for the fees paid by buyers, net of costs related to
acquiring the advertising inventory paid to sellers.
70
Arrangements involving multiple performance obligations primarily consist of combinations of our pay-for-
performance products, Promoted Tweets and Promoted Accounts, which are priced through an auction, and Promoted
Trends, which are priced on a fixed-fee-per day, per geography basis. For arrangements that include a combination of
these products, we develop an estimate of the standalone selling price for these products in order to allocate any potential
discount to all performance obligations in the arrangement. The estimate of standalone selling price for pay-for-
performance auction based products is determined based on the winning bid price. The estimate of standalone selling
price for Promoted Trends is based on Promoted Trends sold on a standalone basis and/or separately priced in a bundled
arrangement by reference to a list price by geography, which is updated and approved periodically. For other
arrangements involving multiple performance obligations where neither auction pricing nor standalone sales provide
sufficient evidence of standalone selling price, we estimate standalone selling price using either an adjusted market
assessment approach or an expected cost plus margin approach. We believe the use of our estimation approach and
allocation of the transaction price on a relative standalone selling price basis to each performance obligation results in
revenue recognition in a manner consistent with the underlying economics of the transaction and the allocation principle
included in Topic 606. We have elected to exclude certain sales and indirect taxes from the determination of the
transaction price.
Income Taxes
We are subject to income taxes in the United States and several foreign jurisdictions. Significant judgment is
required in determining our provision (benefit) for income taxes and income tax assets and liabilities, including evaluating
uncertainties in the application of accounting principles and complex tax laws.
We record a provision (benefit) for income taxes for the anticipated tax consequences of the reported results of
operations using the asset and liability method. Under this method, we recognize deferred income tax assets and liabilities
for the expected future tax consequences of temporary differences between the financial reporting and tax bases of
assets and liabilities, as well as for loss and tax credit carryforwards. Deferred tax assets and liabilities are measured
using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are
expected to be realized or settled. We recognize the deferred income tax effects of a change in tax rates in the period of
the enactment. We record a valuation allowance to reduce our deferred tax assets to the net amount that we believe is
more likely than not to be realized.
We recognize tax benefits from uncertain tax positions if we believe that it is more likely than not that the tax position
will be sustained on examination by the taxing authorities based on the technical merits of the position. Although we
believe we have adequately reserved for our uncertain tax positions (including net interest and penalties), we can provide
no assurance that the final tax outcome of these matters will not be different. We make adjustments to these reserves in
accordance with income tax accounting guidance when facts and circumstances change, such as the closing of a tax
audit. To the extent that the final tax outcome of these matters is different from the amounts recorded, such differences
may impact the provision (benefit) for income taxes in the period in which such determination is made. We record interest
and penalties related to our uncertain tax positions in our provision (benefit) for income taxes.
The Tax Act contains several key tax provisions that affected us, including a reduction of the federal corporate
income tax rate to 21% effective January 1, 2018. We are required to recognize the effect of the tax law changes in the
period of enactment, such as re-measuring our U.S. deferred tax assets and liabilities as well as our valuation allowance
against our net U.S. deferred tax assets. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118,
Income Tax Accounting Implications of the 2017 Tax Cuts and Jobs Act (SAB 118), which allowed us to record provisional
amounts during a measurement period not to extend beyond one year of the enactment date. We completed our
accounting for the Tax Act in the fourth quarter of 2018, within the one year-measurement period from the enactment
date. We elected to account for Global Intangible Low-Taxed Income (GILTI) under the Tax Act as a period cost when the
expense is incurred and apply the approach of tax law ordering for reflecting the realization of loss carryforward expected
to offset future GILTI.
Loss Contingencies
We are involved in various lawsuits, claims, investigations, and proceedings that arise in the ordinary course of
business. Certain of these matters include speculative claims for substantial or indeterminate amounts of damages. We
record a liability when we believe that it is both probable that a loss has been incurred and the amount or range can be
reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. We review
these provisions on a quarterly basis and adjust these provisions accordingly to reflect the impact of negotiations,
settlements, rulings, advice of legal counsel, and updated information.
71
We believe that the amount or estimable range of reasonably possible loss, will not, either individually or in the
aggregate, have a material adverse effect on our business, consolidated financial position, results of operations, or cash
flows with respect to loss contingencies for legal and other contingencies as of December 31, 2018. However, the
outcome of litigation is inherently uncertain. Therefore, if one or more of these legal matters were resolved against us for
amounts in excess of management's expectations, our results of operations and financial condition, including in a
particular reporting period, could be materially adversely affected.
Business Combinations
We account for acquisitions of entities that include inputs and processes and have the ability to create outputs as
business combinations. The purchase price of the acquisition is allocated to the tangible and intangible assets acquired and
liabilities assumed based on their estimated fair values at the acquisition dates. The excess of the purchase price over those
fair values is recorded as goodwill. During the measurement period, which may be up to one year from the acquisition date,
we may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon
the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed,
whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations.
Accounting for business combinations requires our management to make significant estimates and assumptions at
the acquisition date, including estimated fair value of acquired intangible assets, estimated fair value of stock awards
assumed from the acquirees that are included in the purchase price, estimated income tax assets and liabilities assumed
from the acquirees, and determination of the fair value of contractual obligations, where applicable. The estimates of fair
value require management to also make estimates of, among other things, future expected cash flows, discount rates or
expected costs to reproduce an asset. Although we believe the assumptions and estimates we made at the time were
reasonable and appropriate, these estimates are based on historical experience and information obtained from the
management of the acquired companies and are inherently uncertain.
Impact of Recently Issued Accounting Standards
The impact of recently issued accounting standards is set forth in Note 2, Summary of Significant Accounting
Policies, of the Notes to Consolidated Financial Statements under Part II, Item 8 of this Annual Report on Form 10-K.
Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We have operations both within 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 and foreign exchange risks.
Interest Rate Fluctuation Risk
Our investment portfolio mainly consists of short-term fixed income securities, including government and investment-
grade debt securities and money market funds. These securities are classified as available-for-sale and, consequently,
are recorded in the consolidated balance sheets at fair value with unrealized gains or losses, net of tax reported as a
separate component of accumulated other comprehensive loss. Our investment policy and strategy is focused on the
preservation of capital and supporting our liquidity requirements. We do not enter into investments for trading or
speculative purposes.
A rise in interest rates could have a material adverse impact on the fair value of our investment portfolio. Based on
our investment portfolio balance as of December 31, 2018, a hypothetical increase in interest rates of 100 basis points
would result in a decrease of approximately $17.7 million in the fair value of our available-for-sale securities. We currently
do not hedge these interest rate exposures.
In 2014 and 2018, we issued convertible senior notes with in aggregate principal amount of $1.89 billion and $1.15
billion, respectively. We carry the Notes at face value less amortized discount on the consolidated balance sheet. Since
the Notes bear interest at fixed rates, we have no financial statement risk associated with changes in interest rates.
However, the fair value of the Notes changes when the market price of our stock fluctuates or interest rates change.
72
Foreign Currency Exchange Risk
Transaction Exposure
We transact business in various foreign currencies and have international revenue, as well as costs denominated in
foreign currencies, primarily the Euro, British Pound, Singapore Dollar and Japanese Yen. This exposes us to the risk of
fluctuations in foreign currency exchange rates. Accordingly, changes in exchange rates, and in particular a continuing
strengthening of the U.S. dollar, would negatively affect our revenue and other operating results as expressed in U.S.
dollars.
We have experienced and will continue to experience fluctuations in our net loss as a result of transaction gains or
losses related to revaluing and ultimately settling certain asset and liability balances that are denominated in currencies
other than the functional currency of the entities in which they are recorded. Foreign currency net losses were $4.6 million
in 2018. We currently utilize foreign currency forward contracts with financial institutions to reduce the risk that our
earnings may be adversely affected by the impact of exchange rate fluctuations on monetary assets or liabilities
denominated in currencies other than the local currency of a subsidiary. These contracts are not designated as hedging
instruments. We may in the future enter into other derivative financial instruments if it is determined that such hedging
activities are appropriate to further reduce our foreign currency exchange risk. Based on our foreign currency exposures
from monetary assets and liabilities net of our open hedge position, we estimated that a 10% change in exchange rates
against the U.S. dollar would have resulted in a gain or loss of approximately $5.6 million as of December 31, 2018.
Translation Exposure
We are also exposed to foreign exchange rate fluctuations as we translate the financial statements of our foreign
subsidiaries into U.S. dollars in consolidation. If there is a change in foreign currency exchange rates, the translating
adjustments resulting from the conversion of our foreign subsidiaries’ financial statements into U.S. dollars would result in
a gain or loss recorded as a component of accumulated other comprehensive loss which is part of stockholders’ equity.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of Twitter, Inc.
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Twitter, Inc. and its subsidiaries (the “Company”) as
of December 31, 2018 and 2017, and the related consolidated statements of operations, of comprehensive income, of
stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2018, including the
related notes and financial statement schedule listed in the index appearing under Item 15.2 (collectively referred to as the
“consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of
December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial
position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each
of the three years in the period ended December 31, 2018 in conformity with accounting principles generally accepted in
the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal
control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated
Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting,
included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our
responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal
control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company
Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange
Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and
perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of
material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was
maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material
misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that
respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and
disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used
and significant estimates made by management, as well as evaluating the overall presentation of the consolidated
financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal
control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design
and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for
our opinions.
75
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and
procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of
management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the
financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

TWITTER, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note 1. The Company
Twitter, Inc. (“Twitter” or the “Company”) was incorporated in Delaware in April 2007, and is headquartered in San
Francisco, California. Twitter offers products and services for users, advertisers, developers and platform and data
partners.
Note 2. Summary of Significant Accounting Policies
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All
significant intercompany accounts and transactions have been eliminated in consolidation.
Prior Period Reclassifications
Certain prior period amounts have been reclassified to conform to the current period presentation.
Use of Estimates
The preparation of the Company’s consolidated financial statements in conformity with generally accepted
accounting principles in the United States of America (“GAAP”) requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, as well as related disclosure of
contingent assets and liabilities. Actual results could differ materially from the Company’s estimates. To the extent that
there are material differences between these estimates and actual results, the Company’s financial condition or operating
results will be affected. The Company bases its estimates on past experience and other assumptions that management
believes are reasonable based on its knowledge of current events, as well as its expectations about actions it may take in
the future, and evaluates these estimates on an ongoing basis.
Revenue Recognition
The Company generates the substantial majority of its revenue from the sale of advertising services with the balance
from data licensing and other arrangements.
The Company generates its advertising revenue primarily from the sale of its Promoted Products: (i) Promoted
Tweets, (ii) Promoted Accounts and (iii) Promoted Trends. Promoted Tweets and Promoted Accounts are pay-for-
performance advertising products or pay on impressions delivered, each priced through an auction. Promoted Trends are
featured by geography and offered on a fixed-fee-per-day basis. Advertisers are obligated to pay when a user engages
with a Promoted Tweet, follows a Promoted Account, when an impression is delivered, or when a Promoted Trend is
displayed. These advertising services may be sold in combination as a bundled arrangement or separately on a stand-
alone basis.
For the Company's Promoted Product arrangements, significant judgments are (i) identifying the performance
obligations in the contract, (ii) determining the basis for allocating contract consideration to performance obligations, (iii)
determining whether the Company is the principal or the agent in arrangements where another party is involved in
providing specified services to a customer, and (iv) estimating the transaction price to be allocated for contracts with tiered
rebate provisions.
The Company may generate revenue from the sale of certain Promoted Tweets through placement by Twitter of
advertiser ads against third-party publisher content. The Company will pay the third-party publisher a revenue share fee
for its right to monetize their content. In such transactions, advertisers are contracting to obtain a single integrated
advertising service, the Promoted Tweet combined with the third-party publisher content, and the Company obtains
control of the third-party publisher content displayed on Twitter that it then combines with the advertiser ads within the
Promoted Tweet. Therefore, the Company reports advertising revenue generated from these transactions on a gross
basis and records the related third-party content monetization fees as cost of revenue.
82
The Company also generates advertising revenue by selling services in which the Company places ads on third-
party publishers’ websites, applications or other offerings. To fulfill these transactions, the Company purchases
advertising inventory from third-party publishers’ websites and applications where the Company has identified the
advertisers’ targeted audience and therefore incurs traffic acquisition costs prior to transferring the advertising service to
its customers. At such point, the Company has the sole ability to monetize the third-party publishers advertising inventory.
In such transactions, the Company obtains control of a right to a service to be performed by the third-party publishers,
which gives the Company the ability to direct those publishers to provide the services to the Company's customers on the
Company's behalf. Therefore, the Company reports advertising revenue generated from these transactions on a gross
basis and records the related traffic acquisition costs as cost of revenue.
Fees for the advertising services above are recognized in the period when advertising is delivered as evidenced by a
user engaging with a Promoted Tweet or an ad on a third-party publisher website or application in a manner satisfying the
types of engagement selected by the advertisers, such as Tweet engagements (e.g., retweets, replies and likes), website
clicks, mobile application installs or engagements, obtaining new followers, or video views, following a Promoted Account,
delivery of impressions, or through the display of a Promoted Trend on the Company's platform.
The Company has concluded that its data licensing arrangements, which grant customers a right to Twitter’s
intellectual property (“IP”) for a defined period of time, may contain a single performance obligation satisfied at a point in
time (“Historical IP”) or over time (“Future IP”), or may contain two or more performance obligations satisfied separately at
a point in time (Historical IP) and over time (Future IP). In some of the Company's data licensing arrangements, pricing is
a fixed monthly fee over a specified term. In arrangements with a single performance obligation satisfied over time, data
licensing revenue is recognized on a straight-line basis over the period in which the Company provides data as the
customer consumes and benefits from the continuous data available on an ongoing basis. In arrangements with at least
two performance obligations, the Company allocates revenue on a relative basis between the performance obligations
based on standalone selling price (“SSP”) and recognizes revenue as the performance obligations are satisfied.
In other data licensing arrangements, the Company charges customers based on the amount of sales they generate
from downstream customers using Twitter data. Certain of those royalty-based data licensing arrangements are subject to
minimum guarantees. For such arrangements with a minimum guarantee and a single Future IP performance obligation,
the Company recognizes revenue for minimum guarantees on a straight-line basis over the period in which the Company
provides data. For such arrangements with a minimum guarantee and two or more performance obligations, the Company
allocates revenue on a relative basis between the performance obligations based on SSP and recognizes revenue as the
performance obligations are satisfied. Royalties in excess of minimum guarantees, if any, are recognized as revenue in
the period that the related downstream customer sales using the Company’s licensed data occur, and such amounts have
been immaterial to date.
For data licensing arrangements involving two or more performance obligations, the Company uses directly
observable standalone transactions to determine SSP of Historical IP. The Company uses standalone transactions and
considers all other reasonably available observable evidence to estimate SSP of Future IP.
Other revenue is primarily generated from service fees from transactions completed on the Company's mobile ad
exchange. The Company's mobile ad exchange enables buyers and sellers to purchase and sell advertising inventory by
matching them in the exchange. The Company has determined it is not the principal in the purchase and sale of
advertising inventory in transactions between third-party buyers and sellers on the exchange because the Company does
not obtain control of the advertising inventory. The Company reports revenue related to its ad exchange services on a net
basis for the fees paid by buyers, net of costs related to acquiring the advertising inventory paid to sellers.
83
Arrangements involving multiple performance obligations primarily consist of combinations of the Company's pay-
for-performance products, Promoted Tweets and Promoted Accounts, which are priced through an auction, and Promoted
Trends, which are priced on a fixed-fee-per day, per geography basis. For arrangements that include a combination of
these products, the Company develops an estimate of the standalone selling price for these products in order to allocate
any potential discount to all performance obligations in the arrangement. The estimate of standalone selling price for pay-
for-performance auction based products is determined based on the winning bid price. The estimate of standalone selling
price for Promoted Trends is based on Promoted Trends sold on a standalone basis and/or separately priced in a bundled
arrangement by reference to a list price by geography, which is updated and approved periodically. For other
arrangements involving multiple performance obligations where neither auction pricing nor standalone sales provide
sufficient evidence of standalone selling price, the Company estimates standalone selling price using either an adjusted
market assessment approach or an expected cost plus margin approach. The Company believes the use of its estimation
approach and allocation of the transaction price on a relative standalone selling price basis to each performance
obligation results in revenue recognition in a manner consistent with the underlying economics of the transaction and the
allocation principle included in Topic 606. The Company has elected to exclude certain sales and indirect taxes from the
determination of the transaction price.
Cost of Revenue
Cost of revenue includes infrastructure costs, other direct costs including content costs, amortization expense of
technology acquired through acquisitions and amortization of capitalized labor costs for internally developed software,
allocated facilities costs, as well as traffic acquisition costs (“TAC”). Infrastructure costs consist primarily of data center
costs related to the Company’s co-located facilities, which include lease and hosting costs, related support and
maintenance costs and energy and bandwidth costs, as well as depreciation of servers and networking equipment, and
personnel-related costs, including salaries, benefits and stock-based compensation, for its operations teams. Content
costs are primarily related to payments to providers from whom the Company licenses content, in order to increase
engagement on the platform. The fees paid to these content providers may be based on revenues generated, or a
minimum guaranteed fee. TAC consists of costs incurred with third parties in connection with the sale to advertisers of
advertising products that the Company places on third-party publishers’ websites, applications or other offerings
collectively resulting from acquisitions and from the Company’s organically-built advertising network, Twitter Audience
Platform.
Stock-Based Compensation Expense
The Company accounts for stock-based compensation expense under the fair value recognition and measurement
provisions of GAAP. Stock-based awards granted to employees are measured based on the grant-date fair value.
For service-based restricted stock awards and performance-based restricted stock awards without market
conditions, the Company recognizes the compensation expense only for those awards expected to meet the performance
and service vesting condition on a straight-line basis over the requisite service period which is generally one year for
performance vesting condition awards and up to five years for service vesting condition awards. For performance-based
restricted stock awards with market conditions, the Company recognizes the compensation expense on a straight-line
basis over the requisite service period regardless of whether the market condition is satisfied, provided that the requisite
service has been provided. Starting in 2017, the Company accounts for forfeitures as they occur.
The Company estimates the fair value of stock options granted and stock purchase rights provided under the
Company’s employee stock purchase plan using the Black-Scholes option pricing model on the dates of grant. The
compensation expense related to stock options and employee stock purchase rights is recognized on a straight-line basis
over the requisite service period.
The fair value of performance-based restricted stock awards with market conditions is determined using a Monte
Carlo simulation to estimate the grant date fair value.
The Company issues restricted stock subject to a lapsing right of repurchase to continuing employees of certain
acquired companies. Since these issuances are subject to post-acquisition employment, the Company accounts for them
as post-acquisition stock-based compensation expense. The grant-date fair value of restricted stock granted in connection
with acquisitions is recognized as stock-based compensation expense on a straight-line basis over the requisite service
period.
84
Acquisitions
The Company accounts for acquisitions of entities that include inputs and processes and have the ability to create
outputs as business combinations. The purchase price of the acquisition is allocated to the tangible and intangible assets
acquired and liabilities assumed based on their estimated fair values at the acquisition dates. The excess of the purchase
price over those fair values is recorded as goodwill. During the measurement period, which may be up to one year from
the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the
corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of
assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the
consolidated statements of operations.
Investments in Privately-Held Companies
The Company makes strategic investments in privately-held companies. The Company also evaluates each investee
to determine if the investee is a variable interest entity and, if so, whether the Company is the primary beneficiary of the
variable interest entity. The Company’s investments in privately-held companies are primarily non-marketable equity
securities without readily determinable fair values. Prior to January 1, 2018, the Company accounted for its non-
marketable equity securities at cost less impairment. Realized gains and losses on non-marketable securities sold or
impaired were recognized in other income (expense), net. On January 1, 2018, the Company adopted the new standard
which changed the way it accounts for non-marketable securities. The Company now adjusts the carrying value of its non-
marketable equity securities to fair value upon observable transactions for identical or similar investments of the same
issuer or upon impairment (referred to as the measurement alternative). All gains and losses on non-marketable equity
securities, realized and unrealized, are recognized in other income (expense), net.
The Company periodically evaluates the carrying value of the investments in privately-held companies, when events
and circumstances indicate that the carrying amount of the investment may not be recovered. The Company estimates
the fair value of the investments to assess whether impairment losses shall be recorded using Level 3 inputs. These
investments include the Company’s holdings in privately-held companies that are not exchange traded and therefore not
supported with observable market prices; hence, the Company may determine the fair value by reviewing
equity valuation reports, current financial results, long-term plans of the private companies, the amount of cash that the
privately-held companies have on-hand, the ability to obtain additional financing and overall market conditions in which
the private companies operate or based on the price observed from the most recent completed financing.
Loss Contingencies
The Company is involved in various lawsuits, claims, investigations, and proceedings that arise in the ordinary
course of business. The Company records a liability when it believes that it is both probable that a loss has been incurred
and the amount or range can be reasonably estimated. Significant judgment is required to determine both probability and
the estimated amount. The Company reviews these provisions on a quarterly basis and adjust these provisions
accordingly to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information.
Restructuring and Other Charges
The Company records charges associated with management-approved restructuring plans to reduce headcount and
for leases. Restructuring costs are recognized when the related liability is incurred and measured at fair value. The
Company records a liability for employee terminations when all of the following conditions have been met: management,
having the authority to approve the action, commits to a plan of termination; the plan identifies the number of employees
to be terminated, their job classifications and their locations, and the expected completion date; the plan establishes the
terms of the benefit arrangement in sufficient detail to enable employees to determine the type and amount of benefits
they will receive if they are involuntarily terminated; and actions required to complete the plan indicate that it is unlikely
that significant changes to the plan will be made or that the plan will be withdrawn.
The Company accrues for costs to terminate an operating lease or other contract when it terminates the contract in
accordance with the contract terms.
85
A liability for costs that will continue to be incurred under a contract for the remaining term without economic benefits
to the Company is recognized and measured when the entity meets the cease-use date. In recording liabilities for cease-
use facilities, the Company makes various assumptions, including the time period over which the facilities are expected to
be vacant, expected sublease terms and expected sublease rates. The estimates involve a number of risks and
uncertainties, some of which are beyond the Company’s control, including future real estate market conditions and the
Company’s ability to successfully enter into sublease agreements with terms as favorable as those assumed when
arriving at the estimates. The Company regularly evaluates a number of factors to determine the appropriateness and
reasonableness of the restructuring and lease loss accruals including the various assumptions noted above. If actual
results differed significantly from its estimates, the Company may be required to adjust the restructuring and lease loss
accruals in the future.
Operating and Capital Leases
The Company leases office space and data center facilities under operating leases. Certain lease agreements
contain free or escalating rent payment provisions. The Company recognizes rent expense under such leases on a
straight-line basis over the term of the lease. Lease renewal periods are considered on a lease-by-lease basis in
determining the lease term.
The Company also has entered into server and networking equipment lease arrangements with original lease terms
up to four years. The Company’s server and networking equipment leases typically are accounted for as capital leases as
they meet one or more of the four capital lease classification criteria. Assets acquired under capital leases are amortized
over their estimated useful life. As of December 31, 2018 and 2017, the Company had capital lease obligations included
in short-term and long-term capital lease obligations in the consolidated balance sheets of $92.4 million and
$166.3 million, respectively. In the years ended December 31, 2018, 2017 and 2016, the Company recorded
approximately $4.9 million, $5.6 million and $5.5 million, respectively, of interest expense in relation to these capital lease
arrangements.
Cash, Cash Equivalents and Investments
The Company invests its excess cash primarily in short-term fixed income securities, including government and
investment-grade debt securities and money market funds. The Company classifies all liquid investments with stated
maturities of three months or less from date of purchase as cash equivalents. The Company classifies all marketable
securities for use in current operations, even if the security matures beyond 12 months, and presents them as short-term
investments in the consolidated balance sheets.
As of December 31, 2018 and 2017, the Company has restricted cash balances of $1.7 million and $8.3 million,
respectively, within prepaid expenses and other current assets and $25.7 million and $27.1 million, respectively, in other
assets on the accompanying consolidated balance sheets based upon the term of the remaining restrictions. These
restricted cash balances are primarily cash deposits to back letters of credit related to certain property leases.
The Company determines the appropriate classification of its investments in marketable securities at the time of
purchase and reevaluates such designation at each balance sheet date. The Company has classified and accounted for
its marketable securities as available-for-sale. After considering the Company’s capital preservation objectives, as well as
its liquidity requirements, the Company may sell securities prior to their stated maturities. The Company carries its
available-for-sale securities at fair value, and reports the unrealized gains and losses, net of taxes, as a component of
stockholders’ equity, except for unrealized losses determined to be other-than-temporary which are recorded as other
income (expense), net. The Company determines any realized gains or losses on the sale of marketable securities on a
specific identification method and records such gains and losses as a component of other income (expense), net. Interest
earned on cash, cash equivalents, and marketable securities was $111.2 million, $44.4 million, and $24.3 million during
the years ended December 31, 2018, 2017 and 2016, respectively. These balances are recorded in interest income in the
accompanying consolidated statements of operations.
The Company evaluates the investments periodically for possible other-than-temporary impairment. A decline in fair
value below the amortized costs of debt securities is considered an other-than-temporary impairment if the Company has
the intent to sell the security or it is more likely than not that the Company will be required to sell the security before
recovery of the entire amortized cost basis. In those instances, an impairment charge equal to the difference between the
fair value and the amortized cost basis is recognized in earnings. Regardless of the Company’s intent or requirement to
sell a debt security, impairment is considered other-than-temporary if the Company does not expect to recover the entire
amortized cost basis.
86
Concentration of Credit Risk
Financial instruments that potentially subject the Company to significant concentration of credit risk consist primarily
of cash, cash equivalents, short-term investments and accounts receivable. The primary focus of the Company’s
investment strategy is to preserve capital and meet liquidity requirements. The Company’s investment policy addresses
the level of credit exposure by limiting the concentration in any one corporate issuer or sector and establishing a minimum
allowable credit rating. To manage the risk exposure, the Company invests cash equivalents and short-term investments
in a variety of fixed income securities, including government and investment-grade debt securities and money market
funds. The Company places its cash primarily in checking and money market accounts with reputable financial
institutions. Deposits held with these financial institutions may exceed the amount of insurance provided on such deposits,
if any.
The Company’s accounts receivable are typically unsecured and are derived from customers around the world in
different industries. The Company includes terms in its contracts providing the ability to stop transferring promised goods
or services, performs ongoing credit evaluations of its customers, and maintains allowances for potential credit losses.
Historically, such losses have been within management’s expectations. As of December 31, 2018 and 2017, no single
customer accounted for more than 10% of the Company’s net accounts receivable balance. No single customer
accounted for more than 10% of the Company’s revenue in the years ended December 31, 2018, 2017 and 2016.
The Company’s note hedge transactions, entered into in connection with the Notes, as defined and further described
in Note 5 – Fair Value Measurements, and its derivative financial instruments expose the Company to credit risk to the
extent that its counterparties may be unable to meet the terms of the transactions. The Company mitigates this risk by
limiting its counterparties to major financial institutions and using multiple financial institutions as counterparties in its
hedge transactions.
Accounts Receivable, Net
The Company records accounts receivable at the invoiced amount. The Company maintains an allowance for
doubtful accounts to reserve for potentially uncollectible receivable amounts. In evaluating the Company’s ability to collect
outstanding receivable balances, the Company considers various factors including the age of the balance, the
creditworthiness of the customer, which is assessed based on ongoing credit evaluations and payment history, and the
customer’s current financial condition.
Property and Equipment, Net
Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful
lives of the assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease
term or the estimated useful life. The estimated useful lives of property and equipment are described below:
Property and Equipment
Estimated Useful Life
Computer hardware, networking and office equipment .......... Three to five years
Computer software.................................................................. Up to four years
Furniture and fixtures .............................................................. Five years
Leasehold improvements........................................................ Lesser of estimated useful life or remaining lease term
The Company reviews the remaining estimated useful lives of its property and equipment on an ongoing
basis. Management is required to use judgment in determining the estimated useful lives of such assets. Changes in
circumstances such as technological advances, changes to the Company’s business model, changes in the Company’s
business strategy, or changes in the planned use of property and equipment could result in the actual useful lives differing
from the Company’s current estimates. In cases where the Company determines that the estimated useful life of property
and equipment should be shortened or extended, the Company would apply the new estimated useful life prospectively.
The Company reviews property and equipment for impairment when events or changes indicate the carrying amount
may not be recoverable.
Costs of maintenance and repairs that do not improve or extend the lives of the respective assets are expensed as
incurred. Upon retirement or sale, the cost and related accumulated depreciation are removed from the balance sheet and
the resulting gain or loss is reflected in operating expenses.
87
Capitalization of Interest
Interest costs are capitalized for assets that are constructed for the Company’s own internal use, including internally
developed software and property and equipment, for the period of time to get them ready for their intended use. During
the years ended December 31, 2018, 2017 and 2016, the Company capitalized $3.7 million, $3.6 million and $4.3 million
of interest expense, respectively.
Goodwill
Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets
acquired in a business combination. Goodwill is not amortized, but is tested for impairment at least annually or more
frequently if events or changes in circumstances indicate that the asset may be impaired. The Company’s impairment
tests are based on a single operating segment and reporting unit structure. If the carrying value of the reporting unit
exceeds its fair value, an impairment charge is recognized for the excess of the carrying value of the reporting unit over its
fair value.
The Company conducted its annual goodwill impairment test during the fourth quarter of 2018 and determined that
the fair value of the reporting unit significantly exceeded its carrying value. As such, goodwill was not impaired. No
impairment charge was recorded in any of the periods presented in the accompanying consolidated financial statements.
Intangible Assets
Intangible assets are carried at cost and amortized on a straight-line basis over their estimated useful lives of up to
eleven years. The Company reviews identifiable amortizable intangible assets to be held and used for impairment
whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable.
Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting
from use of the asset and its eventual disposition. Measurement of any impairment loss is based on the excess of the
carrying value of the asset over its fair value. There have been no impairment charges recorded in any of the periods
presented in the accompanying consolidated financial statements.
Fair Value Measurements
The Company classifies and discloses assets and liabilities measured at fair value on a recurring basis, as well as
fair value measurements of assets and liabilities measured on a nonrecurring basis in periods subsequent to initial
measurement, in a three-tier fair value hierarchy as described below. Fair value is defined as the exchange price that
would be received for an asset or paid to transfer a liability 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. The three
levels of inputs that may be used to measure fair value are as follows:
Level 1—Observable inputs, such as quoted prices in active markets for identical assets or liabilities.
Level 2—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted
prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data
for substantially the full term of the assets or liabilities.
Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair
value of the assets or liabilities.
Internal Use Software and Website Development Costs
The Company capitalizes certain costs incurred in developing software programs or websites for internal use. In the
years ended December 31, 2018, 2017 and 2016, the Company capitalized costs totaling approximately $121.0 million,
$113.9 million and $139.0 million, respectively. Capitalized internal use software development costs are included in
property and equipment, net. Included in the capitalized amounts above are $41.4 million, $51.8 million and $73.9 million
of stock-based compensation expense in the years ended December 31, 2018, 2017 and 2016, respectively.
The estimated useful life of costs capitalized is evaluated for each specific project and is up to four years. In the
years ended December 31, 2018, 2017 and 2016, the amortization of capitalized costs totaled approximately $111.8
million, $96.5 million and $74.6 million, respectively.
88
Income Taxes
The Company is subject to income taxes in the United States and several foreign jurisdictions. Significant judgment
is required in determining its provision (benefit) for income taxes and income tax assets and liabilities, including evaluating
uncertainties in the application of accounting principles and complex tax laws.
The Company records a provision (benefit) for income taxes for the anticipated tax consequences of the reported
results of operations using the asset and liability method. Under this method, the Company recognizes deferred income
tax assets and liabilities for the expected future tax consequences of temporary differences between the financial
reporting and tax bases of assets and liabilities, as well as for loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax
assets and liabilities are expected to be realized or settled. The Company recognizes the deferred income tax effects of a
change in tax rates in the period of the enactment. The Company records a valuation allowance to reduce its deferred tax
assets to the net amount that it believes is more likely than not to be realized.
The Company recognizes tax benefits from uncertain tax positions only if it believes that it is more likely than not that
the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position.
Although the Company believes it has adequately reserved for its uncertain tax positions (including net interest and
penalties), it can provide no assurance that the final tax outcome of these matters will not be different. The Company
makes adjustments to these reserves in accordance with income tax accounting guidance when facts and circumstances
change, such as the closing of a tax audit. To the extent that the final tax outcome of these matters is different from the
amounts recorded, such differences may impact the provision (benefit) for income taxes in the period in which such
determination is made. The Company records interest and penalties related to our uncertain tax positions in provision
(benefit) for income taxes.
The Tax Cuts and Jobs Act (the “Tax Act”) contains several key tax provisions that affected the Company, including
a reduction of the federal corporate income tax rate to 21% effective January 1, 2018. The Company is required to
recognize the effect of the tax law changes in the period of enactment, such as re-measuring its U.S. deferred tax assets
and liabilities as well as its valuation allowance against its net U.S. deferred tax assets. In December 2017, the SEC staff
issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the 2017 Tax Cuts and Jobs Act (SAB
118), which allowed the Company to record provisional amounts during a measurement period not to extend beyond one
year of the enactment date. The Company completed its accounting for the Tax Act in the fourth quarter of 2018, within
the one-year measurement period from the enactment date. The Company elected to account for Global Intangible Low-
Taxed Income (GILTI) under the Tax Act as a period cost when the expense is incurred, and apply the approach of tax
law ordering for reflecting the realization of loss carryforwards expected to offset future GILTI.
Foreign Currency
The functional currency of the Company's foreign subsidiaries is generally the local currency. The financial
statements of these subsidiaries are translated into U.S. dollars using period-end rates of exchange for assets and
liabilities, historical rates of exchange for equity, and average rates of exchange for revenue and expenses. Translation
gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity.
Unrealized foreign exchange gains and losses due to re-measurement of monetary assets and liabilities denominated in
non-functional currencies as well as realized foreign exchange gains and losses on foreign exchange transactions are
recorded in other income (expense), net in the accompanying consolidated statements of operations.
Advertising Costs
Advertising costs are expensed when incurred and are included in sales and marketing expense in the
accompanying consolidated statements of operations. Advertising expense totaled $78.1 million, $70.2 million and
$114.3 million for the years ended December 31, 2018, 2017 and 2016, respectively.
Comprehensive Income (Loss)
Comprehensive income (loss) consists of two components, net income (loss) and other comprehensive income
(loss). Other comprehensive income (loss) refers to gains and losses that are recorded as an element of stockholders’
equity and are excluded from net income (loss). The Company’s other comprehensive income (loss) is comprised of
unrealized gains or losses on available-for-sale securities, net of tax, and foreign currency translation adjustments.

Recent Accounting Pronouncements
Recently adopted accounting pronouncements
In May 2014, the Financial Accounting Standards Board (FASB) issued a new accounting standard update on
revenue recognition from contracts with customers (“Topic 606”). The new guidance replaces all current GAAP guidance
on this topic and requires entities to recognize revenue when control of the promised goods or services is transferred to
customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those
goods or services. The Company adopted this new accounting standard on January 1, 2018 using the modified
retrospective method. See Note 3 – Revenue for further details.
In January 2016, the FASB issued a new accounting standard update on the classification and measurement of
financial instruments. The new guidance principally affects accounting standards for equity investments, financial liabilities
where the fair value option has been elected, and the presentation and disclosure requirements for financial instruments.
The Company adopted this new accounting standard prospectively for its non-marketable equity securities on January 1,
2018. The Company has elected to use the measurement alternative for its non-marketable equity securities, defined as
cost adjusted for changes from observable transactions for identical or similar investments of the same issuer, less
impairment. The Company’s investments in privately-held companies are non-marketable equity securities without readily
determinable fair values and there was no upward adjustment during the twelve months ended December 31, 2018. See
Note 9 – Acquisitions and Other Investments for further details.
In August 2016, the FASB issued a new accounting standard update on the statement of cash flows. The new
guidance clarifies classification of certain cash receipts and cash payments in the statement of cash flows. The Company
adopted this new accounting standard retrospectively on January 1, 2018, and the adoption did not have a material
impact on the Company’s financial statements.
In October 2016, the FASB issued a new accounting standard update on simplifying the accounting for income taxes
related to intra-entity asset transfers. The new guidance requires an entity to recognize the tax expense from the sale of
an asset in the seller’s tax jurisdiction when the transfers occurs, even though the pre-tax effects of that transaction are
eliminated in consolidation. The Company adopted this new accounting standard on January 1, 2018 using the modified
retrospective method. Upon adoption, the Company recognized an additional deferred tax asset of $29.5 million related to
a prior period intra-entity transfer, which was offset by a full valuation allowance. Therefore, the recognition of the deferred
tax asset upon adoption did not have an impact on the Company’s accumulated deficit. See Note 14 – Income Taxes for
further details.
In November 2016, the FASB issued a new accounting standard update on the presentation of restricted cash in the
statement of cash flows. The new guidance requires an entity to show the changes in the total of cash, cash equivalents,
restricted cash and restricted cash equivalents in the statement of cash flows, and an entity will no longer present
transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash
flows. The Company adopted this new accounting standard retrospectively on January 1, 2018. As a result of the
adoption, net cash used in investing activities was adjusted to exclude the changes in restricted cash, resulting in an
increase of $3.6 million in the previously-reported amount for the twelve months ended December 31, 2017 and a $4.8
million decrease in the previously-reported amount for the twelve months ended December 31, 2016. Restricted cash
balances are primarily cash deposits secured against letters of credit related to certain property leases.
In January 2017, the FASB issued a new accounting standard update on narrowing the definition of a business. The
new guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is
concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and
activities is not a business. The guidance also requires a business to include at least one substantive process and
narrows the definition of outputs. The Company adopted this new accounting standard retrospectively on January 1, 2018
and the adoption did not have a material impact on the Company’s financial statements.
90
Recently issued accounting pronouncements not yet adopted
In February 2016, the FASB issued a new accounting standard update on leases. The new guidance requires
lessees to recognize right-of-use (“ROU”) assets and lease liabilities for operating leases, initially measured at the present
value of the lease payments, on the balance sheet. In addition, it requires lessees to recognize a single lease cost,
calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. This guidance
will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. In July
2018, the FASB issued updated guidance which allows an additional transition method to adopt the new lease standard at
the adoption date, as compared to the beginning of the earliest period presented, and recognize a cumulative-effect
adjustment to the beginning balance of retained earnings in the period of adoption. The Company will adopt the new lease
standard effective January 1, 2019 and will elect to apply all relevant practical expedients permitted under the transition
guidance within the new lease standard with the exception of the practical expedient allowing the use of hindsight in
determining the lease term and in assessing impairment. The standard will have a material impact on the Company’s
consolidated balance sheets, but it will not have a material impact on its consolidated statements of operations, its
consolidated statements of stockholders’ equity, or its consolidated statements of cash flows. The most significant impact
will be the recognition of ROU assets and lease liabilities for operating leases. The accounting for capital leases remains
substantially unchanged. The adoption of the new lease standard on January 1, 2019 is anticipated to result in the
recognition of ROU assets and lease liabilities of approximately $700 million to $800 million.
In June 2016, the FASB issued a new accounting standard update on the measurement of credit losses on financial
instruments. The new guidance requires financial assets measured at amortized cost to be presented at the net amount
expected to be collected and available-for-sale debt securities to record credit losses through an allowance for credit
losses. This guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning after
December 15, 2019. Early adoption is permitted as early as the fiscal years beginning after December 15, 2018. The
Company is evaluating the impact of adopting this new accounting standard update on the financial statements and
related disclosures.
In March 2017, the FASB issued a new accounting standard update on shortening the premium amortization period
for purchased non-contingently callable debt securities. The new guidance shortens the amortization period for the
premium on purchased non-contingently callable debt securities to the earliest call date. Currently, entities generally
amortize the premium as a yield adjustment over the contractual life of the security. This guidance will be effective for
fiscal years, and interim periods within those years, beginning after December 15, 2018. Adoption is not expected to have
a material impact on the Company’s financial statements and related disclosures.
In February 2018, the FASB issued a new accounting standard update to give entities the option to reclassify tax
effects stranded in accumulated other comprehensive income as a result of tax reform to retained earnings (accumulated
deficits). The new guidance also requires entities to make additional disclosures, regardless of whether reclassification of
tax effects is elected. This guidance will be effective for fiscal years, and interim periods within those fiscal years,
beginning after December 15, 2018. The Company will not elect the option to reclassify tax effects as a result of tax
reform and as such, adoption is not expected to have a material impact on the Company’s financial statements and
related disclosures.
In August 2018, the FASB issued a new accounting standard update which eliminates, adds and modifies certain
disclosure requirements for fair value measurements. The update eliminates the requirement to disclose the amount of
and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, and introduces a requirement to
disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value
measurements. This guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning
after December 15, 2019. Adoption is not expected to have a material impact on the Company’s financial statements and
related disclosures.
In August 2018, the FASB issued a new accounting standard update requiring a customer in a cloud computing
arrangement (i.e., hosting arrangement) that is a service contract to capitalize certain implementation costs as if the
arrangement was an internal-use software project. Capitalized implementation costs related to a hosting arrangement that
is a service contract will be amortized over the term of the hosting arrangement, beginning when the module or
component of the hosting arrangement is ready for its intended use. This guidance will be effective for fiscal years, and
interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The Company is
evaluating the impact of adopting this new accounting standard update on its financial statements and related disclosures.

Note 3. Revenue
Adoption of ASC Topic 606, "Revenue from Contracts with Customers"
On January 1, 2018, the Company adopted Topic 606 using the modified retrospective method applied to those
contracts not yet substantially completed as of January 1, 2018. Results for reporting periods beginning after January 1,
2018 are presented under the new revenue standard, while prior period amounts are not adjusted and continue to be
reported in accordance with the Company's historical accounting policies and practices.
Revenue Recognition
Revenue is recognized when the control of promised goods or services is transferred to customers at an amount
that reflects the consideration to which the Company expects to be entitled to in exchange for those goods or services.
The Company identifies its contracts with customers and all performance obligations within those contracts. The Company
then determines the transaction price and allocates the transaction price to the performance obligations within the
Company's contracts with customers, recognizing revenue when, or as, the Company satisfies its performance
obligations. While the majority of the Company's revenue transactions are based on standard business terms and
conditions, the Company also enters into sales agreements with advertisers and data partners that sometimes involve
multiple performance obligations and occasionally include non-standard terms or conditions.
Revenue by geography is based on the billing addresses of the customers. The following table sets forth revenue by
services and revenue by geographic area (in thousands):

Revenue Recognition Accounting Policy
See Note 2 – Summary of Significant Accounting Policies.
Impact of Adoption
The Company recorded a net reduction to opening accumulated deficit of $12.1 million, an increase to unbilled
revenue of $8.0 million, and a reduction to deferred revenue of $4.1 million as of January 1, 2018 due to the cumulative
impact of adopting Topic 606, with the impact primarily related to its data licensing arrangements.
As a result of applying the new standard, the impact for the twelve months ended December 31, 2018 was an
increase to revenue of $16.1 million, an increase to unbilled revenue of $12.6 million, and a reduction to deferred revenue
of $3.5 million, with the impact primarily related to the Company’s data licensing arrangements.
Practical Expedients and Exemptions
92
The Company expenses sales commissions as incurred when the amortization period is one year or less. Sales
commission expenses are recorded within sales and marketing in the consolidated statements of operations.
The Company applied the practical expedient to not disclose the value of remaining performance obligations not yet
satisfied as of period end for contracts with an original expected duration of one year or less.
The Company applied the practical expedient to not disclose the value of remaining performance obligations not yet
satisfied as of period end for variable consideration in the form of sales-based royalties promised in exchange for licenses
to its intellectual property in data licensing contracts.
Contract Balances
The Company enters into contracts with its customers, which may give rise to contract liabilities (deferred revenue)
and contract assets (unbilled revenue). The payment terms and conditions within the Company’s contracts vary by the
type and location of its customer and products or services purchased, the substantial majority of which are due in less
than one year. When the timing of revenue recognition differs from the timing of payments made by customers, the
Company recognizes either unbilled revenue (its performance precedes billing date) or deferred revenue (customer
payment is received in advance of performance).
Deferred Revenue (Contract Liabilities)
The Company records deferred revenue within accrued and other current liabilities in the consolidated balance
sheets. The Company's deferred revenue balance primarily consists of cash payments due in advance of satisfying its
performance obligations relating to data licensing contracts and performance obligations given to customers based on
their spend relating to advertising contracts, for which the Company defers, as they represent material rights. The
Company recognizes deferred revenue relating to its data licensing contracts on a straight-line basis over the period in
which the Company provides data. The Company recognizes deferred revenue relating to its advertising contracts based
on the amount of customer spend and the relative standalone selling price of the material rights.
Unbilled Revenue (Contract Assets)
The Company records unbilled revenue within prepaid expenses and other current assets and other assets in the
consolidated balance sheets. The Company's unbilled revenue primarily consists of amounts that have yet to be billed
under contracts with escalating fee structures. Specifically, because the Company generally recognizes revenue on a
straight-line basis for data licensing arrangements with escalating fee structures, revenue recognized exceeds amounts
the Company has a right to bill during early portions of such contracts, resulting in unbilled revenue.
The following table presents contract balances (in thousands):

January 1,
2018
The amount of revenue recognized in the twelve months ended December 31, 2018 that was included in the
opening deferred revenue balance was $25.9 million. This revenue consists primarily of revenue recognized as a result of
the utilization of bonus media inventory earned by and material rights provided to customers in prior periods.
The amount of revenue recognized from obligations satisfied (or partially satisfied) in prior periods was not material.
The increase in unbilled revenue balance from January 1, 2018 to December 31, 2018 was primarily attributable to
differences between revenue recognized and amounts billed in the Company's data licensing arrangements with
escalating fee structures due to recognizing such fees as revenue on a straight-line basis.
93
The increase in deferred revenue balance from January 1, 2018 to December 31, 2018 was primarily due to cash
payments due in advance of satisfying the Company’s performance obligations relating to data licensing contracts and
bonus and make good media inventory offered to customers during the period, offset by the utilization of such media
inventory issued.
Remaining Performance Obligations
As of December 31, 2018, the aggregate amount of the transaction price allocated to remaining performance
obligations in contracts with an original expected duration exceeding one year is $494.8 million. This total amount
primarily consists of long-term data licensing contracts and excludes deferred revenue related to the Company’s short-
term advertising service arrangements. The Company expects to recognize this amount as revenue over the following
time periods (in thousands):

December 31, 2018 and 2017.
Investments are reviewed periodically to identify possible other-than-temporary impairments. No impairment loss
has been recorded on the securities included in the tables above as the Company believes that the decrease in fair value
of these securities is temporary and expects to recover the initial cost of investment for these securities.
Note 5. Fair Value Measurements
The Company measures its cash equivalents, short-term investments and derivative financial instruments at fair
value. The Company classifies its cash equivalents, short-term investments and derivative financial instruments within
Level 1 or Level 2 because the Company values these investments using quoted market prices or alternative pricing
sources and models utilizing market observable inputs. The fair value of the Company’s Level 1 financial assets is based
on quoted market prices of the identical underlying security. The fair value of the Company’s Level 2 financial assets is
based on inputs that are directly or indirectly observable in the market, including the readily-available pricing sources for
the identical underlying security that may not be actively traded.

In June 2018, the Company issued $1.15 billion in aggregate principal amount of 0.25% convertible senior notes due
in 2024 (the “2024 Notes”) in a private placement to qualified institutional buyers pursuant to Rule144A under the
Securities Act of 1933, as amended. In 2014, the Company issued $935.0 million in aggregate principal amount of 0.25%
convertible senior notes due in 2019 (the “2019 Notes”) and $954.0 million in aggregate principal amount of 1.00%
convertible senior notes due in 2021 (the “2021 Notes” and together with the 2019 Notes and the 2024 Notes, the “Notes”)
in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as
amended. Refer to Note 10 – Convertible Notes for further details on the Notes.
96
The estimated fair value of the 2019 Notes, 2021 Notes, and 2024 Notes, based on a market approach as of
December 31, 2018, was approximately $909.2 million, $872.6 million, and $1.01 billion, respectively, which represents a
Level 2 valuation. The estimated fair value was determined based on the estimated or actual bids and offers of the Notes
in an over-the-counter market on the last business day of the period.
Derivative Financial Instruments
The Company enters into foreign currency forward contracts with financial institutions to reduce the risk that its
earnings may be adversely affected by the impact of exchange rate fluctuations on monetary assets or liabilities
denominated in currencies other than the functional currency of a subsidiary. These contracts do not subject the Company
to material balance sheet risk due to exchange rate movements because gains and losses on these derivatives are
intended to offset gains and losses on the hedged foreign currency denominated assets and liabilities. These foreign
currency forward contracts are not designated as hedging instruments.
The Company recognizes these derivative instruments as either assets or liabilities in the consolidated balance
sheets at fair value based on a Level 2 valuation. The Company records changes in the fair value (i.e., gains or losses) of
the derivatives as other income (expense), net in the consolidated statements of operations. The notional principal of
foreign currency contracts outstanding was equivalent to $545.3 million and $326.1 million at December 31, 2018 and
2017, respectively.

Note 9. Acquisitions and Other Investments
2018 Acquisition
During the year ended 2018, the Company acquired a company, which was accounted for as a business
combination. The purchase price of $53.7 million (paid in shares of the Company’s common stock having a total fair value
of $19.1 million and cash of $34.6 million) for this acquisition was allocated as follows: $9.3 million to developed
technology, $0.4 million to net tangible assets acquired based on their estimated fair value on the acquisition date, and
the excess $44.0 million of the purchase price over the fair value of net assets acquired to goodwill. The goodwill from the
acquisition is mainly attributable to assembled workforce, expected synergies and other benefits. The goodwill is not tax
deductible for U.S. income tax purposes. The developed technology is amortized on a straight-line basis over its
estimated useful life of 24 months.
The results of operations for this acquisition have been included in the Company’s consolidated statements of
operations since the date of acquisition. Actual and pro forma revenue and results of operations for this acquisition have
not been presented because they do not have a material impact on the consolidated revenue and results of operations.
2017 Acquisitions
The Company did not complete any acquisitions during the year ended December 31, 2017.
2016 Acquisitions
During the year ended December 31, 2016, the Company acquired several companies, each of which was
accounted for as a business combination. The total purchase price of $91.4 million (paid in shares of the Company’s
common stock having a total fair value of $1.3 million and cash of $90.1 million) for these acquisitions was allocated as
follows: $14.4 million to developed technologies, $5.0 million to cash acquired, $0.2 million to net tangible assets acquired
based on their estimated fair value on the acquisition date, $2.4 million to deferred tax liability, and the excess
$74.2 million of the purchase price over the fair value of net assets acquired to goodwill. The goodwill from the
acquisitions are mainly attributable to assembled workforce, expected synergies and other benefits. Tax deductible
goodwill resulting from certain of these acquisitions was $63.8 million. The remaining goodwill is not tax deductible for
U.S. income tax purposes. Developed technologies will be amortized on a straight-line basis over their estimated useful
lives of up to 24 months.
The results of operations for each of these acquisitions have been included in the Company’s consolidated
statements of operations since the date of acquisition. Actual and pro forma revenue and results of operations for these
acquisitions have not been presented because they do not have a material impact on the consolidated revenue and
results of operations, either individually or in the aggregate.

Investments in Privately-Held Companies
The Company makes strategic investments in privately-held companies. The Company also evaluates each investee
to determine if the investee is a variable interest entity and, if so, whether the Company is the primary beneficiary of the
variable interest entity. The Company has determined, as of December 31, 2018 there were no variable interest entities
required to be consolidated in the Company’s consolidated financial statements. The Company’s investments in privately-
held companies are primarily non-marketable equity securities without readily determinable fair values. Prior to January
1, 2018, the Company accounted for its non-marketable equity securities at cost less impairment. Realized gains and
losses on non-marketable securities sold or impaired were recognized in other income (expense), net. On January 1,
2018, the Company adopted the new standard which changed the way it accounts for non-marketable securities. The
Company now adjusts the carrying value of its non-marketable equity securities to fair value upon observable transactions
for identical or similar investments of the same issuer or upon impairment (referred to as the measurement alternative). All
gains and losses on non-marketable equity securities, realized and unrealized, are recognized in other income (expense),
net. The Company’s non-marketable equity securities had a carrying value of $25.8 million and $27.6 million as of
December 31, 2018 and 2017, respectively. The maximum loss the Company can incur for its investments is their carrying
value. These investments in privately-held companies are included within other assets on the consolidated balance
sheets.
The Company periodically evaluates the carrying value of the investments in privately-held companies when events
and circumstances indicate that the carrying amount of the investment may not be recovered. The Company estimates
the fair value of the investments to assess whether impairment losses shall be recorded using Level 3 inputs. These
investments include the Company’s holdings in privately-held companies that are not exchange traded and therefore not
supported with observable market prices; hence, the Company may determine the fair value by reviewing equity valuation
reports, current financial results, long-term plans of the privately-held companies, the amount of cash that the privately-
held companies have on-hand, the ability to obtain additional financing and overall market conditions in which the
privately-held companies operate or based on the price observed from the most recent completed financing. In the years
ended December 31, 2018, 2017, and 2016, the Company recorded impairment charges of $3.0 million, $62.4 million, and
$4.0 million, respectively, within other income (expense), net in the consolidated statements of operations.
Note 10. Convertible Notes
2024 Notes
In June 2018, the Company issued $1.15 billion in aggregate principal amount of the 2024 Notes in a private
placement to qualified institutional buyers pursuant to Rule144A under the Securities Act of 1933, as amended. The total
net proceeds from this offering were approximately $1.14 billion, after deducting $12.3 million of debt issuance costs in
connection with the 2024 Notes.
The 2024 Notes represent senior unsecured obligations of the Company. The interest rate is fixed at 0.25% per
annum and is payable semi-annually in arrears on June 15 and December 15 of each year, which commenced on
December 15, 2018.
100
Each $1,000 of principal of the 2024 Notes will initially be convertible into 17.5001 shares of the Company’s
common stock, which is equivalent to an initial conversion price of approximately $57.14 per share, subject to adjustment
upon the occurrence of specified events. Holders of the 2024 Notes may convert the 2024 Notes at their option at any
time on or after March 15, 2024 until close of business on the second scheduled trading day immediately preceding the
maturity date of June 15, 2024. Further, holders of the 2024 Notes may convert all or any portion of their 2024 Notes at
their option prior to the close of business on the business day immediately preceding March 15, 2024, only under the
following circumstances:
1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2018 (and only
during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days
(whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the
immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the notes on
each applicable trading day;
2) during the five business day period after any five consecutive trading day period (as used in this paragraph, the
“measurement period”) in which the trading price (as defined in the Indenture governing the 2024 Notes) per
$1,000 principal amount of 2024 Notes for each trading day of the measurement period was less than 98% of the
product of the last reported sale price of Twitter’s common stock and the conversion rate for the 2024 Notes on
each such trading day; or
3) upon the occurrence of certain specified corporate events.
Upon conversion of the 2024 Notes, the Company will pay or deliver, as the case may be, cash, shares of its
common stock or a combination of cash and shares of its common stock, at the Company’s election. If the Company
satisfies its conversion obligation solely in cash or through payment and delivery, as the case may be, of a combination of
cash and shares of its common stock, the amount of cash and shares of common stock, if any, due upon conversion will
be based on a daily conversion value (as set forth in the indenture governing the 2024 Notes) calculated on a
proportionate basis for each trading day in a 30 trading day observation period.
If a fundamental change (as defined in the indenture governing the 2024 Notes) occurs prior to the maturity date,
holders of the 2024 Notes may require the Company to repurchase all or a portion of their 2024 Notes for cash at a
repurchase price equal to 100% of the principal amount of the 2024 Notes, plus any accrued and unpaid interest to, but
excluding, the repurchase date. In addition, if specific corporate events occur prior to the maturity date of the 2024 Notes,
the Company will be required to increase the conversion rate for holders who elect to convert their 2024 Notes in certain
circumstances.
In accordance with accounting guidance on embedded conversion features, the Company valued and bifurcated the
conversion option associated with the 2024 Notes from the respective host debt instrument, which is referred to as debt
discount, and initially recorded the conversion option of $255.0 million for the 2024 Note in stockholders’ equity. The
resulting debt discount on the 2024 Notes is amortized to interest expense at an effective interest rate of 4.46% over the
contractual terms of the 2024 Notes. The Company allocated $2.7 million of debt issuance costs to the equity component
and the remaining debt issuance costs of $9.6 million are amortized to interest expense under the effective interest rate
method over the contractual terms of the 2024 Notes.
Concurrent with the offering of the 2024 Notes in June 2018, the Company entered into convertible note hedge
transactions with certain bank counterparties whereby the Company has the option to purchase initially (subject to
adjustment for certain specified events) a total of approximately 20.1 million shares of its common stock at a price of
approximately $57.14 per share. The total cost of the convertible note hedge transactions was $268.0 million. In addition,
the Company sold warrants to certain bank counterparties whereby the holders of the warrants have the option to
purchase initially (subject to adjustment for certain specified events) a total of approximately 20.1 million shares of the
Company’s common stock at an initial strike price of $80.20. The Company received $186.8 million in cash proceeds from
the sale of these warrants.
101
Taken together, the purchase of the convertible note hedges and the sale of warrants in connection with the
issuance of the 2024 Notes are intended to offset any actual dilution from the conversion of these 2024 Notes and to
effectively increase the overall conversion price from approximately $57.14 to $80.20 per share. As these transactions
meet certain accounting criteria, the convertible note hedges and warrants are recorded in stockholders’ equity and are
not accounted for as derivatives. The net cost incurred in connection with the convertible note hedge and warrant
transactions was recorded as a reduction to additional paid-in capital in the consolidated balance sheet as of December
31, 2018.
2019 Notes and 2021 Notes
In 2014, the Company issued $935.0 million in aggregate principal amount of 2019 Notes and $954.0 million in
aggregate principal amount of 2021 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A of
the Securities Act of 1933, as amended. The total net proceeds from this offering were approximately $1.86 billion, after
deducting $28.3 million of debt discount and $0.5 million debt issuance costs in connection with the 2019 Notes and the
2021 Notes.
The 2019 Notes and 2021 Notes represent senior unsecured obligations of the Company. The interest rates are
fixed at 0.25% and 1.00% per annum for the 2019 Notes and the 2021 Notes, respectively, and are payable semi-annually
in arrears on March 15 and September 15 of each year, which commenced on March 15, 2015.
Each $1,000 of principal of these Notes will initially be convertible into 12.8793 shares of the Company’s common
stock, which is equivalent to an initial conversion price of approximately $77.64 per share, subject to adjustment upon the
occurrence of specified events. Holders of these notes may convert their notes at their option at any time until close of
business on the second scheduled trading day immediately preceding the relevant maturity date which is March 15, 2019
for the 2019 Notes and March 15, 2021 for the 2021 Notes. Further, holders of each of these notes may convert their
notes at their option prior to the respective dates above, only under the following circumstances:
1) during any calendar quarter commencing after the calendar quarter ending on December 31, 2014 (and only
during such calendar quarters), if the last reported sale price of Twitter’s common stock for at least 20 trading
days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of
the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the
relevant series of notes on each applicable trading day;
2) during the five business day period after any five consecutive trading day period (the “measurement period”) in
which the trading price (as defined in the related Indenture) per $1,000 principal amount of 2019 notes or 2021
notes, as applicable, for each trading day of the measurement period was less than 98% of the product of the last
reported sale price of Twitter’s common stock and the conversion rate for the notes of the relevant series on each
such trading day; or
3) upon the occurrence of certain specified corporate events.
Upon conversion of the 2019 Notes and 2021 Notes, the Company will pay or deliver, as the case may be, cash,
shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election. If the
Company satisfies its conversion obligation solely in cash or through payment and delivery, as the case may be, of a
combination of cash and shares of its common stock, the amount of cash and shares of common stock, if any, due upon
conversion will be based on a daily conversion value (as described herein) calculated on a proportionate basis for each
trading day in a 30 trading day observation period.
If a fundamental change (as defined in the relevant indenture governing the applicable series of Notes) occurs prior
to the maturity date, holders of the 2019 Notes and 2021 Notes may require the Company to repurchase all or a portion of
their notes for cash at a repurchase price equal to 100% of the principal amount of the notes, plus any accrued and
unpaid interest to, but excluding, the repurchase date. In addition, if specific corporate events occur prior to the applicable
maturity date, the Company will be required to increase the conversion rate for holders who elect to convert their notes in
certain circumstances.
102
In accordance with accounting guidance on embedded conversion features, the Company valued and bifurcated the
conversion option associated with the 2019 Notes and 2021 Notes from the respective host debt instrument, which is
referred to as debt discount, and initially recorded the conversion option of $222.8 million for the 2019 Notes and
$283.3 million for the 2021 Notes in stockholders’ equity. The resulting debt discounts on the 2019 Notes and 2021 Notes
are being amortized to interest expense at an effective interest rate of 5.75% and 6.25%, respectively, over the
contractual terms of the notes. The Company allocated $0.1 million of debt issuance costs to the equity component, and
the remaining debt issuance costs of $0.4 million are being amortized to interest expense.
Concurrently with the offering of these Notes in September and October 2014, the Company entered into convertible
note hedge transactions with certain bank counterparties whereby the Company has the option to purchase initially
(subject to adjustment for certain specified events) a total of approximately 24.3 million shares of its common stock at a
price of approximately $77.64 per share. The total cost of the convertible note hedge transactions was $407.2 million. In
addition, the Company sold warrants to certain bank counterparties whereby the holders of the warrants have the option
to purchase initially (subject to adjustment for certain specified events) a total of approximately 24.3 million shares of the
Company’s common stock at a price of $105.28. The Company received $289.3 million in cash proceeds from the sale of
these warrants.
Taken together, the purchase of the convertible note hedges and the sale of warrants are intended to offset any
actual dilution from the conversion of these notes and to effectively increase the overall conversion price from $77.64 to
$105.28 per share. As these transactions meet certain accounting criteria, the convertible note hedges and warrants are
recorded in stockholders’ equity and are not accounted for as derivatives. The net cost incurred in connection with the
convertible note hedge and warrant transactions was recorded as a reduction to additional paid-in capital in 2014.

During the twelve months ended December 31, 2018, 2017, and 2016, the Company recognized $115.4 million,
$88.5 million and $83.9 million, respectively, of interest expense related to the amortization of debt discount and issuance
costs prior to capitalization of interest. The Company recognized $13.4 million of coupon interest expense in the year
ended December 31, 2018, and $11.9 million of coupon interest expense in each of the years ended December 31, 2017
and 2016.
As of December 31, 2018, the remaining life of the 2019 Notes, 2021 Notes, and 2024 Notes is approximately
8 months, 32 months, and 65 months, respectively.
Note 11. Net Income (Loss) per Share
Basic net income (loss) per share is computed by dividing total net income (loss) attributable to common
stockholders by the weighted-average common shares outstanding. The weighted-average common shares outstanding
is adjusted for shares subject to repurchase such as unvested restricted stock granted to employees in connection with
acquisitions, contingently returnable shares and escrowed shares supporting indemnification obligations that are issued in
connection with acquisitions and unvested stock options exercised.
103
Diluted net income (loss) per share is computed by dividing the net income (loss) attributable to common
stockholders by the weighted-average number of common shares outstanding including potential dilutive common stock
instruments. In the years ended December 31, 2017 and 2016, the Company’s potential common stock instruments such
as stock options, RSUs, shares to be purchased under the 2013 Employee Stock Purchase Plan, shares subject to
repurchases, conversion feature of the Notes and the warrants were not included in the computation of diluted loss per
share as the effect of including these shares in the calculation would have been anti-dilutive.

Since the Company expects to settle the principal amount of the outstanding Notes in cash, the Company uses the
treasury stock method for calculating any potential dilutive effect of the conversion spread on diluted net income per
share, if applicable. For the 2019 Notes and 2021 Notes, the conversion spread of 24.3 million shares will have a dilutive
impact on diluted net income per share of common stock when the average market price of the Company’s common stock
for a given period exceeds the conversion price of $77.64 per share. For the 2024 Notes, the conversion spread of
20.1 million shares will have a dilutive impact on diluted net income per share of common stock when the average market
price of the Company’s common stock for a given period exceeds the conversion price of $57.14 per share.
104
If the average market price of the common stock exceeds the exercise price of the warrants, $105.28 for the 2019
Notes and 2021 Notes, and $80.20 for the 2024 Notes, the warrants will have a dilutive effect on the earnings per share
assuming that the Company is profitable. Since the average market price of the common stock is below $80.20 for all
periods presented, the warrants are anti-dilutive.
Note 12. Preferred Stock
The Company has the authority to issue up to 200,000,000 shares of preferred stock and to determine the price,
rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by
the stockholders. As of December 31, 2018 and 2017, there was no preferred stock outstanding.
Note 13. Common Stock and Stockholders’ Equity
Common Stock
As of December 31, 2018, the Company is authorized to issue 5.0 billion shares of $0.000005 par value common
stock in accordance with the Certificate of Incorporation, as amended and restated.
Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive
dividends whenever funds are legally available and when and if declared by the Board of Directors, subject to the prior
rights of holders of all classes of stock outstanding. As of December 31, 2018, no dividends have been declared.
Equity Incentive Plans
The Company’s 2013 Equity Incentive Plan serves as the successor to the 2007 Equity Incentive Plan. Initially,
68.3 million shares were reserved under the 2013 Equity Incentive Plan and any shares subject to options or other similar
awards granted under the 2007 Equity Incentive Plan that expire, are forfeited, are repurchased by the Company or
otherwise terminate unexercised will become available under the 2013 Equity Incentive Plan. The number of shares of the
Company’s common stock available for issuance under the 2013 Equity Incentive Plan were and will be increased on the
first day of each fiscal year beginning with the 2014 fiscal year, in an amount equal to the least of (i) 60,000,000 Shares,
(ii) 5% of the outstanding Shares on the last day of the immediately preceding fiscal year or (iii) such number of Shares
determined by the Company’s Board of Directors. As of December 31, 2018, the total number of options, RSUs, and
PRSUs outstanding under the 2013 Equity Incentive Plan was 32.5 million shares, and 176.0 million shares were
available for future issuance. There were 2.5 million shares of options outstanding under the 2007 Equity Incentive Plan
as of December 31, 2018. No additional shares have been issued under the 2007 Equity Incentive Plan since 2013.
Options granted under the Company’s Equity Incentive Plans generally expire 10 years after the grant date. The
Company issues new shares to satisfy stock option exercises.
On May 25, 2016, the Company’s stockholders approved the 2016 Equity Incentive Plan. A total of 6,814,085 shares
were reserved under the 2016 Equity Incentive Plan, which equals the number of shares that the Jack Dorsey Revocable
Trust dated December 8, 2010 (the “Jack Dorsey Trust”), for which Jack Dorsey, the Company’s Chief Executive Officer,
serves as trustee, gave back and contributed to the Company without any cost or charge to the Company. All such shares
have been retired and cancelled by the Company. A maximum aggregate number of 6,814,085 shares were reserved
under the 2016 Equity Incentive Plan and are available for grants.
The Company also assumed stock options of acquired entities in connection with certain acquisitions. While the
respective stock plans were terminated on the closing of each acquisition, they continue to govern the terms of stock
options assumed in the respective acquisition.
105
Restricted Common Stock
The Company has granted restricted common stock to certain continuing employees in connection with the
acquisitions. Vesting of this stock is dependent on the respective employee’s continued employment at the Company
during the requisite service period, which is up to four years from the issuance date, and the Company has the right to
repurchase the unvested shares upon termination of employment. The fair value of the restricted common stock issued to
employees is recorded as compensation expense on a straight-line basis over the requisite service period.
The activities for the restricted common stock issued to employees for the year ended December 31, 2018 are

Employee Stock Purchase Plan
On November 7, 2013, the Company’s 2013 Employee Stock Purchase Plan (the “ESPP”) became effective. The
ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll
deductions of up to 15% of their eligible compensation, subject to any plan limitations. The ESPP provides for twelve-
month offering periods, and each offering period will include purchase periods, which will be the approximately six-month
period commencing with one exercise date and ending with the next exercise date. Employees are able to purchase
shares at 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 exercise date. The number of shares available for sale under the ESPP were and will be increased
annually on the first day of each fiscal year, equal to the least of i) 11.3 million shares; ii) 1% of the outstanding shares of
the Company’s common stock as of the last day of the immediately preceding fiscal year; or iii) such other amount as
determined by the Board of Directors.
During the years ended December 31, 2018 and 2017, employees purchased an aggregate of 1.5 million and
1.7 million shares, respectively, under this plan at a weighted average price of $19.03 and $13.79 per share, respectively.

In December 2017, the Tax Act was enacted into law and the new legislation contains several key provisions that
affected the Company, including a reduction of the federal corporate income tax rate to 21% effective January 1, 2018.
The Company is required to recognize the effect of the tax law changes in the period of enactment, such as re-measuring
its U.S. deferred tax assets and liabilities as well as its valuation allowance against its net U.S. deferred tax assets. Also in
December 2017, the SEC staff issued SAB 118, which allowed the Company to record provisional amounts during a
measurement period not to extend beyond one year of the enactment date. During the fourth quarter of 2018, the
Company completed its accounting for the Tax Act as summarized below:
•
•
•
•
The Company previously recognized a provisional reduction in its deferred tax assets, with a corresponding
decrease to the valuation allowance of the same amount, related to the revaluation of deferred tax assets and
liabilities. No adjustments were made to the provisional estimates recorded due to the full valuation allowance
upon adoption.
The Company was not subject to the one-time mandatory transition tax.
The Company elected to record the taxes for GILTI as period costs.
The Company elected to utilize tax law ordering for reflecting the realization of the net operating losses expected
to offset future GILTI.
The Company has recorded a valuation allowance of $14.6 million and $780.2 million against its gross U.S. federal
deferred tax asset balance as of December 31, 2018, and December 31, 2017, respectively, as well as a valuation
allowance of $196.3 million and $222.9 million against its gross state deferred tax asset balance as of December 31,
2018, and December 31, 2017, respectively.
111
During the year ended December 31, 2018, the Company released $797.4 million of the valuation allowance related
to most of the United States federal and all states deferred tax assets with the exception of California and Massachusetts.
The Company continues to maintain a valuation allowance related to specific net deferred tax assets where it is not more
likely than not that the deferred tax assets will be realized, which include all capital losses and California and
Massachusetts net deferred tax assets. The Company concluded, based upon the preponderance of positive evidence
(i.e. cumulative profit before tax adjusted for permanent items over the previous twelve quarters, a history of taxable
income in recent periods, and the current forecast of income before taxes for the United States going forward) over
negative evidence and the anticipated ability to use the deferred tax assets, that it was more likely than not that the
deferred tax assets could be realized. If there are unfavorable changes to actual operating results or to projections of
future income, the Company may determine that it is more likely than not such deferred tax assets may not be realizable.
At December 31, 2018, the Company had $2.85 billion of U.S. federal and $1.30 billion of state net operating losses,
which will begin to expire in 2034 for federal and 2026 for state tax purposes, if not utilized.
The Company also has $300.4 million and $236.2 million of U.S. federal and state research credit carryforwards,
respectively. The U.S. federal credit carryforward will begin to expire in 2027. The state research tax credits have no
expiration date. Additionally, the Company has California Enterprise Zone Credit carryforwards of $19.1 million which will
begin to expire in 2023.
Utilization of the net operating loss and credit carryforwards may be subject to an annual limitation due to the
ownership change limitations provided by the Internal Revenue Code of 1986, as amended (the “Code”), and similar state
provisions. Any annual limitation may result in the expiration of net operating losses and credits before utilization.
Also during the year ended December 31, 2018, the Company released the valuation allowance related to deferred
tax assets of its Brazilian operations that resulted in a net benefit to tax expense of $47.7 million. The Company reported
cumulative profit before tax (adjusted for permanent items) over the previous twelve quarters in its Brazilian operations
based on U.S. GAAP and expects that net operating loss carryovers and other deductible amounts in Brazil will ultimately
be realizable against future profits. The Company concluded, based upon the preponderance of positive evidence over
negative evidence and the anticipated ability to use the deferred tax assets, that it was more likely than not that the
deferred tax assets in Brazil would be realizable due to U.S. GAAP forecasted profits for Twitter Brazil. If there are
unfavorable changes to actual operating results or to projections of future income, the Company may determine that it is
more likely than not such deferred tax assets may not be realizable.
As of December 31, 2018, the unrecognized tax benefit was $332.3 million, including $317.5 million of unrecognized
tax benefits which, if recognized, will not affect the annual effective tax rate as these unrecognized tax benefits would
increase deferred tax assets which would be subject to a full valuation allowance, and the remaining $14.8 million of
unrecognized tax benefits which, if recognized, would affect the annual effective tax rate. A reconciliation of the beginning
and ending amount of unrecognized tax benefit is as follows (in thousands):

The Company recognizes interest and/or penalties related to income tax matters as a component of income tax
expense. In 2018, the Company recognized net interest and penalties of $2.2 million in income tax expense. As of
December 31, 2018, the Company recorded $3.1 million of interest and penalties related to uncertain tax positions.
The Company is subject to taxation in the United States and various state and foreign jurisdictions. Earnings from
non-US activities are subject to local country income tax. The material jurisdictions in which the Company is subject to
potential examination by taxing authorities include the United States, California and Ireland. The Company is currently
under examination in California for tax years 2013 through 2015. The Company believes that adequate amounts have
been reserved in these jurisdictions. The Company’s 2007 to 2017 tax years remain subject to examination by the United
States and California due to tax attributes, and its 2014 to 2017 tax years remain subject to examination in Ireland. The
Company remains subject to possible examination in various other jurisdictions that are not expected to result in material
tax adjustments. The Company does not believe that its unrecognized tax benefits will materially change within the next
12 months.
Note 15. Commitments and Contingencies
Credit Facility
In August 2018, the Company entered into a revolving credit agreement with certain lenders, which provides for a
$500.0 million unsecured revolving credit facility maturing on August 7, 2023. In connection with entering into the $500.0
million credit facility, the Company also terminated its $1.0 billion unsecured revolving credit facility. The Company is
obligated to pay interest on loans under the new credit facility and other customary fees for a credit facility of this size and
type, including an upfront fee and an unused commitment fee. The interest rate for the new credit facility is determined
based on calculations using certain market rates as set forth in the credit agreement. As of December 31, 2018, no
amounts had been drawn under the credit facility.
Operating and Capital Leases
The Company has entered into various non-cancelable operating lease agreements for certain offices and data
center facilities with contractual lease periods expiring between 2019 and 2028. During the year ended December 31,
2018 and 2017, the Company entered into several sublease agreements for office space that the Company is not fully
utilizing. The Company also has lease arrangements for certain server and networking equipment that are accounted for
as capital leases and included in property and equipment on the consolidated balance sheets.

Legal Proceedings
Beginning in September 2016, multiple putative class actions and derivative actions were filed in state and federal
courts in the United States against Twitter, Twitter’s directors, and/or certain officers alleging false and misleading
statements in violation of securities laws and breach of fiduciary duty. The putative class actions were consolidated in the
U.S. District Court for the Northern District of California. On October 16, 2017, the court granted in part and denied in part
the Company’s motion to dismiss. On July 17, 2018, the court granted plaintiffs' motion for class certification in the
consolidated securities action. The Company disputes the claims and intends to continue to defend the lawsuits
vigorously.
The Company is also currently involved in, and may in the future be involved in, legal proceedings, claims,
investigations, and government inquiries arising in the ordinary course of business. These proceedings, which include
both individual and class action litigation and administrative proceedings, have included, but are not limited to matters
involving content on the platform, intellectual property, privacy, securities, employment and contractual rights. Legal fees
and other costs associated with such actions are expensed as incurred. The Company assesses, in conjunction with its
legal counsel, the need to record a liability for litigation and contingencies. Litigation accruals are recorded when and if it
is determined that a loss related matter is both probable and reasonably estimable. Material loss contingencies that are
reasonably possible of occurrence, if any, are subject to disclosure. As of December 31, 2018, except for the above
referenced class actions and derivative actions, there was no litigation or contingency with at least a reasonable possibility
of a material loss. No material losses have been recorded during the years ended December 31, 2018, 2017 and 2016
with respect to litigation or loss contingencies.
Non-Income Taxes
The Company is under audit by various domestic and foreign tax authorities and currently involved in a number of
tax disputes related to non-income tax matters. The subject matter of non-income tax audits primarily arises from disputes
on the tax treatment and tax rate applied to the sale of the Company’s products and services in these jurisdictions and the
tax treatment of certain employee benefits. The Company accrues non-income taxes that may result from examinations
by, or any negotiated agreements with, these tax authorities when a loss is probable and reasonably estimable. If the
Company determines that a loss is reasonably possible and the loss or range of loss can be estimated, it discloses the
reasonably possible loss or range of loss. The Company believes these matters are without merit and it is defending itself
vigorously. Due to the inherent complexity and uncertainty of these matters and judicial process in certain jurisdictions, the
final outcome may be materially different from the Company’s expectations.
Indemnification
In the ordinary course of business, the Company often includes standard indemnification provisions in its
arrangements with its customers, partners, suppliers and vendors. Pursuant to these provisions, the Company may be
obligated to indemnify such parties for losses or claims suffered or incurred in connection with its service, breach of
representations or covenants, intellectual property infringement or other claims made against such parties. These
provisions may limit the time within which an indemnification claim can be made. It is not possible to determine the
maximum potential amount under these indemnification obligations due to the limited history of prior indemnification
claims and the unique facts and circumstances involved in each particular agreement. The Company has never incurred
significant expense defending its licensees against third-party claims, nor has it ever incurred significant expense under its
standard service warranties or arrangements with its customers, partners, suppliers and vendors. Accordingly, the
Company had no liabilities recorded for these provisions as of December 31, 2018 and 2017.
Note 16. Related Party Transactions
In September 2015, the Company entered into a partnership agreement for no consideration with Square, Inc., for
which Jack Dorsey (the Company’s Chief Executive Officer) serves as Chief Executive Officer, to enable U.S. political
donations through Tweets. Neither Square, Inc. nor the Company will pay each other any amounts in connection with the
agreement. The agreement has no impact on the Company’s consolidated financial statements.

Certain of the Company’s directors have affiliations with customers of the Company. The Company recognized
revenue under contractual obligations from such customers of $25.9 million and $22.5 million for the years ended
December 31, 2018 and December 31, 2017, respectively. No revenue was recognized under contractual obligations from
such customers for the year ended December 31, 2016. The Company had outstanding receivable balances of $3.8
million and $4.2 million from such customers as of December 31, 2018 and December 31, 2017, respectively.
Note 17. Employee Benefit Plan
The Company has a 401(k) Plan that qualifies as a deferred compensation arrangement under Section 401 of the
Internal Revenue Code. Under the 401(k) Plan, participating employees may defer a portion of their pretax earnings not to
exceed the maximum amount allowable. Matching contributions are based upon the amount of the employees’
contributions subject to certain limitations. The matching contributions made by the Company were $6.3 million for the
year ended December 31, 2018 and $2.8 million for each of the years ended December 2017 and 2016.
Note 18. Segment Information and Operations by Geographic Area
The Company has a single operating segment and reporting unit structure. The Company’s chief operating decision-
maker is the Chief Executive Officer who reviews financial information presented on a consolidated basis for purposes of
allocating resources and evaluating financial performance.

Note 19. Restructuring Charges
On October 25, 2016, the Board of Directors of the Company approved a reduction in force plan (“2016 Plan”) of up
to approximately 9% of the Company’s positions globally. The reduction in force was undertaken to eliminate investment
in noncore areas and drive toward greater efficiency, while allowing the Company to continue to invest in its highest
priorities.
On December 17, 2016, the Board of Directors of the Company approved a lease abandonment plan (“2016 Lease
Plan”) to abandon excess office space with lease terms expiring through 2028.

Item 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL
DISCLOSURE
None.
Item 9A. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated
the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report on
Form 10-K. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of a company
that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits
under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s
rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to
ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange
Act is accumulated and communicated to the company’s management, including its principal executive and principal
financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required
disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can
provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in
evaluating the cost-benefit relationship of possible controls and procedures. The design of disclosure controls and
procedures and internal control over financial reporting must reflect the fact that there are resource constraints and that
management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their
costs. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of
December 31, 2018, our disclosure controls and procedures were effective at the reasonable assurance level.
Changes in Internal Control over Financial Reporting
There was no change in our internal control over financial reporting identified in connection with the evaluation
required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended December 31,
2018 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Management's Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting
(as defined in Rule 13a-15(f) under the Exchange Act). Our management conducted an assessment of the effectiveness
of our internal control over financial reporting based on the criteria established in “Internal Control - Integrated Framework”
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that
assessment, our management has concluded that our internal control over financial reporting was effective as of
December 31, 2018. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2018
has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their
report which appears herein.
