2020
ANNUAL REPORT

2020 Milestones:

• Revenue for our fiscal year 2020 was $2.32 billion. We now serve over
7,000 customers and continue to add new customers and expand our
market presence. Our customers span a range of several sectors
including public cloud providers (cloud titans), service and cloud
specialty providers and enterprise customers including financial
companies.

• In October 2020, Arista acquired Awake Security, a Network Detection

and Response (NDR) platform provider that combines artificial
intelligence with human expertise to autonomously hunt and respond
to insider and external threats.

• In February 2020, Arista acquired Big Switch Networks, a network
monitoring and software defined networking pioneer for multi-cloud
visibility.

• Arista expanded its Cognitive Campus portfolio with the flagship

modular POE chassis 750 Series for high port density, efficient power
and embedded security and automation.

• Arista introduced its optical line system for 400G, Arista OSFP-LS,

which is a highly compact, low power and cost-effective solution for
increasing bandwidth between data centers without the need for
external optical line systems.

• Arista also launched a network observability software, DANZ

Monitoring Fabric, on Arista switching platforms for enterprise-wide
traffic visibility and contextual insights. In light of the recent cyber
attacks, Arista introduced Attack Surface Assessment service, through
our acquisition of Awake Security.

• Arista Networks recognized as a leader in The Forrester Wave™: Open,
Programmable Switches for A Businesswide SDN, Q3 2020 with the
top score in the strategy category.

• This is the sixth consecutive year Arista Networks has been recognized
in the Leaders Quadrant of the 2020 Gartner Magic Quadrant for Data
Center Networking published on 30 June 2020.

Customers believe that COVID-19 has actually increased the value and
relevance of the network in the post-pandemic era. We are building upon
our cloud networking heritage to unify data sets consistently and
harnessing and archiving data across one software stack (EOS and one
CloudVision).

Looking ahead, Arista is helping customers with their transformation to a
data-centric cloud-first world. We are optimistic in helping the networking
industry transition and change to modern data-driven networking.

I thank Arista stockholders, customers, partners and our employees for
your continued support.

2020 was a challenging year, in the
face of the COVID-19 pandemic and
resulting economic uncertainty,
combined with unprecedented
adjustments to our operations. I am
extremely proud and grateful to the
Arista family for the dedication,
resilience and empathy they have
shown over the past year, working
diligently with suppliers and partners to
help our customers navigate the
challenges.

Despite this, we executed well against
our mission of helping customers with
their transformation to a data-centric
cloud-first strategy. We made
significant progress in extending cloud
networking principles to the enterprise
and campus markets with our
Cognitive Cloud Networking approach.
In addition, we completed the
acquisitions of Big Switch Networks
and Awake Security, broadening our
network software offerings. This
diversification of the business from
both a customer and product
perspective, contributed to a return to
revenue growth in the fourth quarter of
2020 to position Arista well for growth
momentum into 2021.

Our Commitment to Corporate, Environmental
and Social Responsibility

Arista is committed to designing, manufacturing and delivering leading software driven cloud networking solutions in an
environmentally and socially sustainable manner. We believe that sustainability and business growth are closely linked,
and delivering products that are sustainable truly enables our customers’ success. Arista’s commitment to corporate,
environmental and social responsibility is focused on the following key areas:

Ethical Business Conduct

• Our Code of Ethics and Business Conduct (the “Code”) emphasizes the importance of honest business

conduct and solid business ethics. The Code applies to all personnel employed by or engaged to provide
services to the Company including, but not limited to, our employees, officers and directors, including our
Chief Executive Officer, Chief Financial Officer, and other executive and senior financial officers. The Code
addresses, among other things, conflicts of interest, business practices, compliance with laws and
regulations, and interacting fairly and respectfully with each other, our customers, partners, suppliers and
host communities. The full text of the Code and our Corporate Governance Guidelines are posted on the
Governance section of our website at http://investors.arista.com.

• We are committed to complying with applicable international and domestic anti-corruption laws,
including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and applicable local laws.
Our Anti-Corruption Compliance Policy & Guidelines outline the parameters of what is acceptable
and what is not acceptable from an anti-corruption view. We have established procedures for
conducting due diligence on our partners, manufacturers, suppliers, logistics providers and other
third parties that may interact with foreign officials on our behalf.

• Our whistleblower policy encourages transparency, facilitates confidentiality, and provides multiple avenues

for employees and non-employees to submit concerns about accounting, auditing or other matters.

• We are committed to maintaining the highest level of professional and ethical standards in the

conduct of our business around the world. We believe our reputation for integrity and fair dealing is
an important component of our success and the personal satisfaction of our employees.

People

• We believe that diversity and inclusion play an important role in attracting and retaining the best

talent, enhancing our organizational performance and ultimately improving shareholder value. We
desire to maintain an open and inclusive environment where people feel valued, included and
accountable. We recognize that gender and racial disparities remain a challenge in our industry
and are deeply committed to addressing this issue.

• Our efforts start at the top with a diverse management team that includes our Chief Executive

Officer, Chief Financial Officer and Group Vice President and Worldwide Human Resources and
Operations who are all women, and our Chief Executive Officer, Chief Operating Officer and Senior
Vice President of WW Customer Engineering who are people of color.

• To extend this diversity throughout the organization, we are increasing recruitment and

engagement efforts for women and members of underrepresented communities including building
programs to promote a broader and more diverse pool of candidates for job openings, providing
top employees with career opportunities, maintaining pay equity among our employees and
nurturing an inclusive community.

• For example, we are actively promoting the hiring of female engineers through the hosting of periodic

technology sessions for female engineers. We also support under-represented employee affinity
organizations and actively recruit from underrepresented universities and professional societies,
including professional societies that support Black engineers, Latin Americans and veterans.

• We work hard to reinforce the principles of diversity and inclusion within our workplace community. These
principles are codified in our Code of Ethics and Business Conduct which affirms our commitment to
equal employment opportunity, without regard to any protected characteristic, including but not limited

4

2021 PROXY STATEMENT

to race, religion, national origin, color, gender, age, disability, pregnancy, marital status, military status or
sexual orientation. We believe all employees should be treated with dignity and respect. We seek to
educate on these expectations by requiring periodic training on our Code of Ethics and Business
Conduct, Anti-Corruption Compliance Policy & Guidelines, anti-harassment and other matters.

Health and Safety

• We are committed to protecting the health and safety of our employees, visitors, and the public.
Our policy is to maintain our facilities and run our business operations in a manner that does not
jeopardize the occupational health and safety of employees.

• We promote health through wellness events. Arista holds quarterly Employee Health & Wellness Days to
raise awareness on health issues and increase education on preventive medicine and available services.
Our wellness events focus on physical well-being, nutrition, emotional well-being and holistic health.

• During the COVID-19 pandemic, Arista formed an internal task force that developed policies,

procedures, safety training and protocols for the safety of our employees. Arista maintains a focus
on supporting employee wellness through the pandemic and launched a COVID toolkit for
employees and an on-going webinar series focused on providing information and resources about
remote working, parenting and family, kids learning, physical health and nutrition and support
through our Employee Assistance Program. Arista also implemented facilities improvements for
the safety of our employees during the pandemic.

Social Responsibility

• As an integral part of our corporate culture, we maintain an active community engagement

program to provide opportunities for our employees to participate in community service. While the
COVID pandemic created challenges with in-person volunteering, Arista was able to quickly shift
to organizing virtual volunteer opportunities, including adding local detail to maps with the Missing
Maps Project and the American Red Cross in preparation for disasters.

• Through our Foundation, Arista gives annually to select non-profit organizations. Our Foundation’s giving
priorities are generally to non-profits focused on education, hunger or environmental sustainability. In
2020, Arista donated to Friends of the Children New York and Code2040, among others.

• Immediately after the outbreak of the COVID pandemic, Arista committed to working with key hospitals
across the country to donate critical networking gear to accelerate the adoption of new technologies.
The Arista Foundation directly funded critical COVID-19 medical research through generous grants to
Stanford Medical and Gladstone / UCSF, and ultimately enabled Nobel Prize winning research. The
Arista Foundation also provided global COVID community aid through grants to the American Red
Cross, the World Health Organization, PM Cares India and the Temple Street Hospital, Dublin, Ireland.

• In 2020, through the personal efforts of Arista executive Pravin Bhagwat and India non-profit

partner, 14 Trees Foundation, we planted another 20,000 trees in 2020 for a cumulative 75,000
trees to-date worldwide.

• In late 2020, inspired by unprecedented global need caused by the pandemic, Arista launched our first
global employee fundraising event with the goal of providing food to people in need. Over 1.1 million
meals were provided through a combination of employee donations and matching Arista Foundation
funds through our partners, Second Harvest of Silicon Valley, Feeding America, New Hampshire Food
Bank, Central Texas Food Bank, Food Bank of Central and Eastern North Carolina, Greater Vancouver
Food Bank, Foodcloud, Ireland and Foodbank, Australia, in the largest Arista philanthropy event ever.

• Additionally, in immediate response to some of the worst wildfires in recent Bay Area history,

Arista employees and the Arista Foundation donated funds to assist those displaced and in need
of aid in Santa Cruz County through our partner the Community Foundation of Santa Cruz County.

5

• We are committed to responsible sourcing of materials for our products. We are a member of the
Responsible Minerals Initiative (“RMI”) and have management systems in place to ensure that
components are sourced responsibly. Arista’s suppliers are asked to take reasonable due
diligence to determine if the minerals that they use are sourced from certified conflict-free
smelters, which are validated by the RMI.

Environmental

• Sustainability & Environmental Management

In 2021, Arista amended its Audit Committee charter to provide that the Audit Committee has
responsibility for reviewing and discussing with management the Company’s policies and practices
relating to environmental and social responsibility matters. In addition, Arista created a Sustainability
Committee that sets the direction and strategy on sustainability matters and oversees execution of
sustainability initiatives. We also implemented an environmental management system that outlines our
objectives for achieving pollution prevention, environmental protection and monitoring, and continual
improvements in the environmental performance of our operations.

• LEED Gold Certification & Efficient Offices

o When we select our office space, we ensure that we have an office that not only meets our

needs, but also aids us in reducing our impact to the environment. Our Santa Clara
headquarters and our San Francisco office are both LEED Gold certified. The certification,
awarded by the U.S. Green Building Council, is based on the properties’ use of sustainable
materials, water and energy efficiency, indoor environmental quality, location and
transportation, and overall innovation. We also consider energy efficient real estate for our
international operations and we moved our Bangalore operations to a facility that was built
according to LEED Gold Level rating benchmarks.

o Our headquarters includes environmentally friendly features such as floor-to-ceiling windows that filter

heat and maximize natural light and energy efficient lighting, heating, cooling and ventilation. In
addition, high efficiency plumbing fixtures and landscape irrigation systems are installed to conserve
water at a critical time for California. We also promote alternative commuting with onsite electric
vehicle charging stations, priority parking for hybrid vehicles and bike lockers throughout our campus.

• Electronic Industry Citizenship Coalition Membership

Arista is a member of the Responsible Business Alliance (“RBA”) and supports the RBA’s vision and
mission, which strives to develop a global electronics industry supply chain that consistently operates
with social, environmental and economic responsibility through a common code of conduct, collaborative
efforts and shared tools and practices. Arista is committed to progressively aligning its own operations
with the RBA code of conduct and encourages its own first-tier suppliers to do the same.

• Design for Environment

We are committed to integrating sustainability in every aspect of our products’ life cycles, from the
materials that make up our products, all the way to the end of life of the product, while meeting our
customers’ requirements. For example, we have implemented Design for Environment principles in
our development process with the goal of minimizing the overall adverse environmental impact of our
products, with a focus on the reduction of material diversity and weight, selection of more
environmentally friendly materials, ease of disassembly and recycling, energy efficiency, design for
longevity and upgradeability, and design for efficient packaging.

• Product Design Efficiency & Recycling

As a producer of hardware products, Arista offers a takeback and recycle program in our U.S. and
European markets, which allows our customers to return end of life products and dispose of them
in an environmentally safe manner.

o Our product design philosophy follows the principles of Design for Environment, which

considers the environmental impact of the product during the design process. We consider
product material weight reduction, environmentally friendly material usage, energy efficiency,
ease of recycling, options for reuse and refurbishing, and efficient packaging.

6

2021 PROXY STATEMENT

o Since the operation of our datacenter products can require a large amount of energy, we work
to improve energy efficiency of new products to save on energy and reduce greenhouse gas
emissions during the products’ use phase. We have found that minimizing and upgrading
components in product hardware design while simplifying the architecture can provide
improved performance and throughput relative to power consumption. In addition, our new
products use Platinum and Titanium efficiency power supplies, which reduce the total product
power consumption and heat generated from the power supply.

• Supply Chain

We believe that it is essential to extend our environmental sustainability and social responsibility
efforts to our supply chain. We request that our suppliers report energy, greenhouse gas, water
and waste data through the RBA, and we perform periodic risk assessments of our suppliers.

• Waste Management

We follow the simple rule of using less, reusing where possible and ensuring that the materials we
use in our operations and in our products are recyclable. We are working to continually expand
our recycling and reuse efforts. In recent years, we increased the amount of metal and packaging
recycled and reduced our waste to landfill.

or by a bank or other nominee, you are considered the
beneficial owner of those shares held in “street name,” and

nominee, who is considered the stockholder of record with
respect to those shares. As the beneficial owner, you have
the right to direct your broker or nominee how to vote your
shares. Beneficial owners are also invited to attend the
Annual Meeting. However, since a beneficial owner is not
the stockholder of record, you may not vote your shares of
our common stock at the Annual Meeting unless you follow
your broker’s procedures for obtaining a legal proxy.
Throughout this proxy, we refer to stockholders who hold
their shares through a broker, bank or other nominee as
“street name stockholders.”

Q What is a quorum?

A A quorum is the minimum number of shares

required to be present at the Annual Meeting

for the Annual Meeting to be properly held under our
amended and restated bylaws and Delaware law. The
presence (including by proxy) of a majority of all issued

the Annual Meeting. Abstentions, withhold votes and
broker non-votes are counted as shares present and

virtual meeting, which will be conducted via a
live webcast. You are entitled to participate in the Annual

Q What is the effect of giving a proxy?

A Proxies are solicited by and on behalf of our

board of directors. Jayshree Ullal, Ita

Brennan and Marc Taxay have been designated as
proxies by our board of directors. When a proxy is
properly dated, signed and returned, the shares
represented by such proxy will be voted at the Annual
Meeting in accordance with the instructions of the
stockholder contained on such proxy. If no specific
instructions are given, however, the shares will be voted
in accordance with the recommendations of our board
of directors as described above. If any matters not
described in this proxy statement are properly presented
at the Annual Meeting, the proxy holders will use their
own judgment to determine how to vote the shares.

Q Why did I receive a Notice of Internet

Availability of Proxy Materials instead of a
full set of proxy materials?

A In accordance with the rules of the Securities

and Exchange Commission (“SEC”), we have

elected to furnish our proxy materials, including this
proxy statement and our annual report, primarily via the
Internet. The Notice containing instructions on how to
access our proxy materials is first being mailed on or
about April 21, 2021 to all stockholders entitled to vote
at the Annual Meeting. Stockholders may request to
receive all future proxy materials in printed form by mail
or electronically by e-mail by following the instructions
contained in the Notice. We encourage stockholders to
take advantage of the availability of our proxy materials
on the Internet to help reduce the environmental impact
of our annual meetings of stockholders.

Meeting?

Q How are proxies solicited for the Annual

A Our board of directors is soliciting proxies for

use at the Annual Meeting. All expenses
associated with this solicitation will be borne by us.
Copies of solicitation materials will also be made
available upon request to brokers, banks and other
nominees to forward to the beneficial owners of the
shares held of record by such brokers, banks or other
nominees. The original solicitation of proxies may be
supplemented by solicitation by telephone, electronic
communication, or other means by our directors,
officers and employees.

Q Where can I find the voting results of the

Annual Meeting?

A We will announce preliminary voting results at

the Annual Meeting. We will also disclose

voting results on a Current Report on Form 8-K that we
will file with the SEC within four business days after the
Annual Meeting. If final voting results are not available to
us in time to file a Current Report on Form 8-K within
four business days after the Annual Meeting, we will file
a Current Report on Form 8-K to publish preliminary
results and will provide the final results in an amendment
to this Current Report on Form 8-K as soon as they
become available.

Questions and Answers

No additional compensation will be paid to these
individuals for any such services, although we may
reimburse such individuals for their reasonable
out-of-pocket expenses in connection with such
solicitation. We may also reimburse brokerage firms,
banks and other agents for the cost of forwarding proxy
materials to beneficial owners. We will reimburse brokers
or other nominees for reasonable expenses that they
incur in sending our proxy materials to you if a broker or
other nominee holds shares of our common stock on
your behalf.

Q How may my brokerage firm or other

intermediary vote my shares if I fail to
provide timely directions?

A Brokerage firms and other intermediaries

holding shares of our common stock in street

name for customers are generally required to vote such
shares in the manner directed by their customers. In the
absence of timely directions, your broker will have
discretion to vote your shares on our sole “routine”
matter: the proposal to ratify the appointment of Ernst &
Young LLP. Your broker will not have discretion to vote
on the election of directors or on the approval, on an
advisory basis, of executive compensation of our named
executive officers, which are “non-routine” matters,
absent direction from you.

2021 PROXY STATEMENT

BOARD OF DIRECTORS & CORPORATE GOVERNANCE

Our business affairs are managed under the direction of our board of directors. Our board of directors is divided into three
staggered classes of directors. At each annual meeting of stockholders, a class of directors will be elected for a three-
year term to succeed the same class whose term is then expiring. Our board of directors is committed to good corporate
governance practices. These practices provide an important framework within which our board of directors and
management can pursue our strategic objectives for the benefit of our stockholders. Our board of directors has adopted
Corporate Governance Guidelines that address items such as the qualifications and responsibilities of our directors and
director candidates and corporate governance policies and standards applicable to us in general. We believe that good
governance leads to high board effectiveness, promotes the long-term interests of our stockholders, strengthens the
accountability of the board of directors and management, and improves our standing as a trusted member of the
communities we serve.

Board of Directors and Corporate Governance

Board Composition Overview

Consistent with the Company’s Corporate Governance Guidelines, the nominating and corporate governance committee
considers, among other factors, issues of character, integrity, judgment, diversity, independence, area of expertise such
as appropriate financial and other expertise relevant to our business, corporate experience, length of service, potential
conflicts of interest and other commitments when reviewing and making recommendations to the board of directors
regarding the composition and size of the board. We believe that diversity with respect to tenure is important in order to
provide for both fresh perspectives and deep experience and knowledge of the Company. Although our board of
directors does not maintain a specific policy with respect to board diversity, our board of directors believe that our board
of directors should be a diverse body and our nominating and corporate governance committee considers a broad range
of backgrounds and experiences in making determinations regarding nominations of directors and in overseeing the
annual board of director and committee evaluations.

Board of Directors and Corporate Governance

Key Elements of Board Independence at Arista

Our board of director’s independence enables it to be objective and critical in carrying out its oversight responsibilities.
The Corporate Governance Guidelines provide that a substantial majority of our directors will be independent.

Our board of directors has undertaken a review of the independence of each director. Based on information provided by
each director concerning his or her background, employment and affiliations, our board of directors has made the
following determinations:

• 6/8 of the directors are independent: We are

• Lead independent director: Lead independent

committed to maintaining a substantial majority of
directors who are independent of the Company and
management. Except for our employee directors, all
director nominees are independent.

• Committee independence: Only independent
directors are members of board committees.

• Executive sessions: Our independent directors
meet in executive session at each board and audit
committee meeting.

director provides leadership to the board of directors
and particularly to the independent directors.

• Independent compensation consultant: The

compensation consultant retained by the
Compensation Committee is independent of the
Company and management

In making the determination that Mr. Giancarlo is independent, the board of directors considered the fact that
Mr. Giancarlo is chief executive officer and a member of the board of directors of Pure Storage, Inc., and we sell products
to and purchase products from Pure Storage, Inc. in the ordinary course of business. The board of directors determined
that Mr. Giancarlo did not have a direct or indirect material interest in these transactions. Furthermore, payments made to
us by Pure Storage, Inc. pursuant to such transactions did not exceed the greater of $1 million or 2% of Pure Storage,
Inc.’s consolidated gross revenues in any of the last three fiscal years. As a result, the board of directors concluded that
these transactions would not affect Mr. Giancarlo’s independence.

Director Commitments

Our board of directors recognizes that all members of our board of directors should dedicate sufficient time and attention
to fulfill the responsibilities required of directors. In assessing whether directors and nominees for director have sufficient
time and attention to devote to board duties, our board of directors considers, among other things, whether directors may
be “overboarded,” which refers to the situation where a director serves on an excessive number of boards. In addition,
prior to recommending a candidate as a nominee for director, the nominating and corporate governance committee
reviews the number of boards that the candidate serves on and considers whether those outside commitments may limit
the ability of the candidate to devote sufficient time and attention to board duties.

Our board of directors believes that each of our directors, including each of our director nominees, has demonstrated the ability
to devote sufficient time and attention to board duties and to otherwise fulfill the responsibilities required of directors.

In addition, our board of directors discussed with Ms. Mather whether her service on the audit committees of more than
three public companies would impair her ability to serve on our audit committee. The Board noted that Ms. Mather’s
service on other audit committees enables her to bring additional experience to her service on our audit committee.
Based on their review, our board of directors determined that Ms. Mather’s service on more than three public company
audit committees will not impair her ability to effectively serve on our audit committee.

Board Leadership Structure

We believe that the structure of our board of directors and its committees provides strong overall management of our
Company. While the Chairman of our board of directors and our Chief Executive Officer roles are separate, our current
Chairman, Andreas Bechtolsheim, is not independent under the listing standards of the New York Stock Exchange as a

18

2021 PROXY STATEMENT

Board of Directors and Corporate Governance

result of his employment with us. Our board of directors believes that, given the perspective and experience
Mr. Bechtolsheim brings as one of our founders, Mr. Bechtolsheim’s service as our Chairman is appropriate and is in the
best interests of our board of directors, our Company and our stockholders.

Our Chief Executive Officer is responsible for setting the strategic direction of our Company, the general management and
operation of the business and the guidance and oversight of senior management. The Chairman of our board of directors
monitors the content, quality and timeliness of information sent to our board of directors and is available for consultation
with our board of directors regarding the oversight of our business affairs.

Lead Independent Director

Recognizing the importance of strong independent oversight, our board of directors has appointed Mr. Scheinman to
serve as our lead independent director.

While the Chairman directs the operations of the board of directors and is responsible for the overall management and
effective functioning of the board of directors, the lead independent director provides leadership to the board of directors
and particularly to the independent directors.

The lead independent director communicates with the Chief Executive Officer, disseminates information to the rest of the
board of directors in a timely manner, and raises issues with management on behalf of the outside directors when
appropriate. In addition, the lead independent director’s responsibilities include the following:

• calling meetings of outside directors when necessary

• ensuring that the board of directors fulfills its

and appropriate;

• being available, when appropriate, for consultation and

direct communication with the Company’s stockholders;

• building a productive relationship between the board

of directors and the CEO;

Board Meetings and Committees

oversight responsibilities in Company strategy, risk
oversight and succession planning; and

• performing such other duties as the board of
directors may from time to time designate.

During our fiscal year ended December 31, 2020, each director attended at least 75% of the aggregate of (i) the total number of
meetings of our board of directors held during the period for which he or she has been a director and (ii) the total number of
meetings held by all committees of our board of directors on which he or she served during the periods that he or she served.

Our Corporate Governance Guidelines set out that the Company encourages, but does not require, our directors to
attend the annual meeting of stockholders. All of our board members attended our 2020 annual meeting.

Board of Directors and Corporate Governance

Compensation Committee Interlocks and Insider Participation
None of the members of our compensation committee is or has been an officer or employee of our Company. None of
our executive officers currently serves, or in the past year has served, as a member of the board of directors or
compensation committee (or other board committee performing equivalent functions or, in the absence of any such
committee, the entire board) of any entity that has one or more of its executive officers serving on our board of directors
or compensation committee.

Considerations in Evaluating Director Nominees
In accordance with the Company’s Corporate Governance Guidelines, in its evaluation of director candidates, including
the members of the board of directors eligible for re-election, the nominating and corporate governance committee will
consider: (a) the current size and composition of the board of directors, (b) the needs of the board of directors and the
respective committees of the board of directors, (c) such factors as character, integrity, judgment, diversity of experience,
independence, area of expertise, corporate experience, length of service, potential conflicts of interest, other
commitments and the like, and (d) other factors that the nominating and corporate governance committee may consider
appropriate. The nominating and corporate governance committee will also consider gender composition requirements
imposed by applicable law. The nominating and corporate governance committee evaluates these factors, among others,
and does not assign any particular weighting or priority to any of these factors.

The nominating and corporate governance committee requires the following minimum qualifications to be satisfied by any
nominee for a position on the board of directors: (a) the highest personal and professional ethics and integrity, (b) proven
achievement and competence in the nominee’s field and the ability to exercise sound business judgment, (c) skills that are
complementary to those of the existing board of directors, (d) the ability to assist and support management and make
significant contributions to the Company’s success, and (e) an understanding of the fiduciary responsibilities that is
required of a member of the board of directors and the commitment of time and energy necessary to diligently carry out
those responsibilities.

The nominating and corporate governance committee will evaluate any recommendation for nominations to our board of
directors in accordance with its charter, our amended and restated bylaws, our policies and procedures for director

Guidelines, the nominating and corporate governance committee will consider candidates for our board of directors
recommended by stockholders holding at least one percent (1%) of the fully diluted capitalization of the Company
continuously for at least twelve (12) months prior to the date of the submission of the recommendation so long as such
recommendations and nominations comply with the certificate of incorporation and bylaws of the Company and
applicable laws. Such recommendations must include information about the candidate, including but not limited to, a
statement of support by the recommending stockholder, evidence of the recommending stockholder’s ownership of our
common stock and a signed letter from the candidate acknowledging that as a member of our board of directors, the

discretion to decide which individuals to recommend for nomination as directors.

Risk Management

Risk is inherent with every business and we face a number of risks, including strategic, financial, business and
operational, legal and compliance, and reputational. We have designed and implemented processes to manage risk in our
operations. Management is responsible for the day-to-day management of risks the Company faces while our board of
directors has responsibility for the oversight of risk management. Our board committees assist our board of directors in
fulfilling its oversight responsibilities in certain areas of risk.

Our audit committee reviews the Company’s risk management processes and procedures, including our internal controls
and procedures on financial reporting, our investment policies, and our compliance programs with respect to legal, ethical
and regulatory requirements. The management and internal audit teams provide periodic updates on cybersecurity risks
and other risks to the audit committee. Further, the audit committee receives reports and presentations from
management on the Company’s risk assessment and mitigation programs, compliance matters, and cybersecurity
activities, and the results of various internal audit projects. Key information is shared with the Board by the audit
committee.

Executive Talent Management and Succession Planning

Our board of directors places a high priority on senior management development and succession planning and
recognizes that thoughtful succession planning is critical to creating long-term shareholder value.

Pursuant to our Corporate Governance Guidelines, the nominating and corporate governance committee, in consultation with
the full board of directors, is primarily responsible for succession planning for the role of chief executive officer. In addition, the
nominating and corporate governance committee monitors management’s succession plans for other key executives.

The nominating and corporate governance committee evaluates our key executives, discusses their development and
develops succession plans with the view of ensuring that a strong pipeline of talent is being developed for planned or
unplanned events. In addition, our lead independent director facilitates discussions among independent directors about
succession planning at executive sessions.

Director Compensation

The following table provides information regarding the total compensation that was granted to each of our directors who
was not serving as an executive officer in 2020. Directors who are also our employees do not receive additional

Board of Directors and Corporate Governance

With respect to 2020 board service, our board of directors approved compensation to each of our non-employee
directors as follows:

• a $75,000 cash retainer for general board service,
except that our lead independent director received
a $120,000 cash retainer;

• a $12,000 cash retainer for chairing the nominating

and corporate governance committee;

• a $10,000 cash retainer for service on each

• a $25,000 cash retainer for chairing the audit

committee.

committee

• a $12,000 cash retainer for chairing the

compensation committee;

Prior to April 2020, under our outside director compensation policy, each director elected at an annual meeting was
granted restricted stock units on the date of the annual meeting with a total value of $750,000 (based on the average
closing stock price for the 30 trading day period ending on the applicable annual meeting) that vested quarterly over three
years.

In April 2020, our compensation committee recommended, and our board of directors approved, a revised policy for
annual equity grants to outside board members of restricted stock units with a total value of $225,000 (based on the
average closing stock price for the 30 trading day period ending on the grant date) that vest quarterly (on each Company
standard quarterly vesting date following the grant date) over one year and are subject to continued service on the board
(the “Revised Director Equity Policy”). Grants under the Revised Director Equity Policy shall be automatic immediately
following an applicable annual meeting. For our Class III non-employee directors re-elected at the 2020 annual meeting,
the annual equity grants began upon their re-election and (i) for our Class I non-employee directors, the annual equity
grants will begin upon their re-election at the 2021 annual meeting and (ii) for our Class II non-employee directors, the
annual equity grants will begin upon their re-election at the 2022 annual meeting.

STOCK OWNERSHIP GUIDELINES

In April 2019, our board of directors adopted stock ownership guidelines. Our stock ownership guidelines are designed to
encourage our directors and our Chief Executive Officer to achieve and maintain a meaningful equity stake in our
Company and more closely align their interests with those of our stockholders. The guidelines provide that our
non-employee directors should accumulate and hold investment levels of three times the annual cash base retainer for
service on the board of directors within five years from the later of the date of the adoption of the stock ownership
guidelines or the date such director is appointed or elected.

All of our directors and our Chief Executive Officer are on track to meet these guidelines based on their current rate of
stock accumulations in the time frames set out in the guidelines.

2021 PROXY STATEMENT

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Our board of directors is currently composed of eight members. In accordance with our amended and restated certificate
of incorporation, our board of directors is divided into three staggered classes of directors. At the Annual Meeting, three
Class I directors will be elected for a three-year term to succeed the same class whose term is then expiring.

Each director’s term continues until the election and qualification of his or her successor, or such director’s earlier death,
resignation, or removal. Any increase or decrease in the number of directors will be distributed among the three classes
so that, as nearly as possible, each class will consist of one-third of our directors. This classification of our board of
directors may have the effect of delaying or preventing changes in control of our Company.

Nominees
Our nominating and corporate governance committee has recommended, and our board of directors has approved, Kelly
Battles, Andreas Bechtolsheim and Jayshree Ullal, as nominees for election as Class I directors at the Annual Meeting. If
elected, each of Kelly Battles, Andreas Bechtolsheim and Jayshree Ullal will serve as Class I directors until the 2024
annual meeting of stockholders and until their successors are duly elected and qualified. Each of the nominees is currently
a director of our Company. Ms. Battles, who was appointed to the board by our other directors in July 2020, was initially
suggested to the nominating and corporate governance committee of the board for consideration as a potential director
by our Chief Executive Officer. For information concerning the nominees, please see the section titled “Board of Directors
and Corporate Governance.”

If you are a stockholder of record and you sign your proxy card or vote by telephone or over the Internet but do not give
instructions with respect to the voting of directors, your shares will be voted “FOR” the re-election of:

• Kelly Battles 

• Andreas Bechtolsheim 

• Jayshree Ullal

Kelly Battles, Andreas Bechtolsheim and Jayshree Ullal have each consented to
being a nominee and to serving as a director, if elected; however, in the event that a
director nominee is unable to serve as a director at the time of the Annual Meeting,
the proxies will be voted for any nominee who shall be designated by our board of
directors to fill such vacancy. If you are a street name stockholder and you do not
give voting instructions to your broker or nominee, your broker will leave your shares
unvoted on this matter.

Vote Required
The election of directors is by plurality vote. “Plurality” means that the nominees who receive the largest number of votes
cast “for” are elected as directors. As a result, any shares not voted “for” a particular nominee (whether as a result of a
withheld vote or a broker non-vote) will not be counted in such nominee’s favor and will have no effect on the outcome of
the election. You may vote “for” or “withhold” on each of the nominees for election as a director.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE
“FOR” EACH OF THE NOMINEES NAMED ABOVE.

PROPOSAL NO. 2

ADVISORY VOTE ON EXECUTIVE
COMPENSATION

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, enables stockholders
to approve, on an advisory or non-binding basis, the compensation of our named executive officers as disclosed pursuant
to Section 14A of the Securities Exchange Act of 1934. This proposal, commonly known as a “say-on-pay” proposal,
gives our stockholders the opportunity to express their views on our named executive officers’ compensation as a whole.
This vote is not intended to address any specific item of compensation or any specific named executive officer, but rather
the overall compensation of all of our named executive officers and the philosophy, policies and practices described in
this proxy statement.

The say-on-pay vote is advisory, and therefore not binding on us, the compensation committee or our board of directors.
The say-on-pay vote will, however, provide information to us regarding investor sentiment about our executive
compensation philosophy, policies and practices, which the compensation committee will be able to consider when
determining executive compensation for the remainder of the current fiscal year and beyond. Our board of directors and
our compensation committee value the opinions of our stockholders and to the extent there is any significant vote against
the named executive officer compensation as disclosed in this proxy statement, we will communicate directly with
stockholders to better understand the concerns that influenced the vote, consider our stockholders’ concerns and the
compensation committee will evaluate whether any actions are necessary to address those concerns.

We believe that the information provided in the “Executive Compensation” section of this proxy statement, and in
particular the information discussed in “Executive Compensation—Compensation Discussion and Analysis—Executive
Compensation Philosophy and Objectives” beginning on page 37 below, demonstrates that our executive compensation
program was designed appropriately and is working to ensure management’s interests are aligned with our stockholders’
interests to support long-term value creation. Accordingly, we ask our stockholders to vote “FOR” the following resolution
at the Annual Meeting:

“RESOLVED, that the stockholders approve, on an advisory basis, the compensation paid to the named executive
officers, as disclosed in the proxy statement for the Annual Meeting pursuant to the compensation disclosure rules of the
SEC, including the compensation tables and narrative discussion, and other related disclosure.”

Vote Required
The advisory vote on executive compensation requires the affirmative vote of a majority of the shares of our common
stock present at the Annual Meeting (including by proxy) and entitled to vote thereon. Abstentions will have the effect of a
vote AGAINST the proposal and broker non-votes will have no effect.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL
OF THE ADVISORY RESOLUTION ON EXECUTIVE COMPENSATION.

RATIFICATION OF APPOINTMENT
OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

Our audit committee has appointed Ernst & Young LLP (“EY”), an independent registered public accounting firm, to audit
our consolidated financial statements for our fiscal year ending December 31, 2021. During our fiscal year ended
December 31, 2020, EY served as our independent registered public accounting firm.

Notwithstanding the appointment of EY and even if our stockholders ratify the appointment, our audit committee, in its
discretion, may appoint another independent registered public accounting firm at any time during our fiscal year if our
audit committee believes that such a change would be in the best interests of our Company and stockholders. At the
Annual Meeting, our stockholders are being asked to ratify the appointment of EY as our independent registered public
accounting firm for our fiscal year ending December 31, 2021. Our audit committee is submitting the appointment of EY
to our stockholders because we value our stockholders’ views on our independent registered public accounting firm and
as a matter of good corporate governance. Representatives of EY are expected to attend the Annual Meeting virtually and
they will have an opportunity to make a statement and will be available to respond to appropriate questions from our
stockholders.

If our stockholders do not ratify the appointment of EY, our audit committee may reconsider the appointment of EY.

Fees Paid to the Independent Registered Public Accounting Firm

regulatory filings or engagements for those fiscal years.

(2) Audit-Related Fees consist of fees for professional services for assurance and related services that are reasonably related to the performance of the audit or review of our

consolidated financial statements and are not reported under “Audit Fees.” These services include accounting consultations concerning financial accounting and

Auditor Independence
In our fiscal year ended December 31, 2020, there were no other professional services provided by EY, other than those
listed above, that would have required our audit committee to consider their compatibility with maintaining the
independence of EY.

Proposal No. 3—Ratification of Appointment of Independent Registered Public Accounting Firm

Audit Committee Policy on Pre-Approval of Audit and Permissible
Non-Audit Services of Independent Registered Public Accounting
Firm

Our audit committee has established a policy governing our use of the services of our independent registered public
accounting firm. Under the policy, our audit committee is required to pre-approve all audit and non-audit services
performed by our independent registered public accounting firm in order to ensure that the provision of such services
does not impair the public accountants’ independence. All services and fees paid to EY for our fiscal years ended
December 31, 2019 and 2020 were pre-approved by our audit committee.

Vote Required
The ratification of the appointment of EY requires the affirmative vote of a majority of the shares of our common stock
present at the Annual Meeting (including by proxy) and entitled to vote thereon. Abstentions will have the effect of a vote
AGAINST the proposal and broker non-votes will have no effect.

REPORT OF THE AUDIT COMMITTEE

The audit committee is a committee of the board of directors comprised solely of independent directors as required by
the listing standards of the New York Stock Exchange and rules and regulations of the SEC. The audit committee
operates under a written charter approved by the board of directors, which is available on the Governance section of our
website at http://investors.arista.com. The composition of the audit committee, the attributes of its members and the
responsibilities of the audit committee, as reflected in its charter, are intended to be in accordance with applicable
requirements for corporate audit committees. The audit committee reviews and assesses the adequacy of its charter and
the audit committee’s performance on an annual basis.

With respect to the Company’s financial reporting process, the management of the Company is responsible for
(1) establishing and maintaining internal controls and (2) preparing the Company’s consolidated financial statements. Our
independent registered public accounting firm, Ernst & Young LLP (“EY”), is responsible for auditing these financial
statements. It is the responsibility of the audit committee to oversee these activities. It is not the responsibility of the audit
committee to prepare our financial statements. These are the fundamental responsibilities of management. In the
performance of its oversight function, the audit committee has:

• reviewed and discussed the audited financial

• received the written disclosures and the letter from

statements with management and EY;

• discussed with EY the matters required to be
discussed by Auditing Standard No. 1301,
“Communications with Audit Committees,” as
issued by the Public Company Accounting
Oversight Board, and the Securities and Exchange
Commission; and

EY required by applicable requirements of the
Public Company Accounting Oversight Board
regarding the independent accountant’s
communications with the audit committee
concerning independence, and has discussed with
EY its independence.

Based on the audit committee’s review and discussions with management and EY, the audit committee recommended to
the board of directors that the audited financial statements be included in the Annual Report on Form 10-K for the fiscal
year ended December 31, 2020 for filing with the SEC.

Respectfully submitted by the members of the audit committee of the board of directors:

Ann Mather (Chair)

Overview

FISCAL 2020 BUSINESS HIGHLIGHTS

Our executive compensation program is designed to align the compensation of our executives with our operating and
financial performance and create value for our stockholders. Accordingly, you should consider our executive
compensation decisions in the context of our financial and operational performance during fiscal 2020, including:

6th YEAR 

LEADERSHIP POSITION 

Revenue for our fiscal 2020 was $2.32 billion, representing a decrease of 3.9%
compared to fiscal 2019, and slightly below our internal targets set at the beginning of
the year. We experienced strong sales to our enterprise and other cloud and service
provider customers, but this was more than offset by reduced sales from our larger
customers, combined with the impact of some COVID-19 related supply constraints.
We exited the year with over 7,000 customers and continue to add new customers
and expand and diversify our market position.

Our non-GAAP operating income for fiscal 2020 was $874.8 million or 37.7% of
revenue, compared to $922.7 million or 38.3% of revenue in fiscal 2019. The
decrease in non-GAAP operating margins was largely a result of reduced revenue for
the year, offset in part by an improvement in non-GAAP gross margins. The ratio of
non-GAAP operating income to revenue is a key metric for our stockholders as it
provides a consistent measure of the profitability of our business and as a result we
used non-GAAP operating income as a metric in our 2020 Bonus Plan (as defined
below).

This is the sixth consecutive year Arista Networks has been recognized in the Leaders
Quadrant of the 2020 Gartner Magic Quadrant for Data Center Networking published
on 30 June 2020.

In 2020, Arista acquired Awake Security, a Network Detection and Response (NDR)
platform provider that combines artificial intelligence with human expertise to
autonomously hunt and respond to insider and external threats. Arista also acquired
Big Switch Networks, a network monitoring and Software Defined Networking (SDN)
pioneer.

In 2020, Arista expanded its Cognitive Campus portfolio with the new 750 Series
modular chassis for enhanced security solutions and simplified automation workflows.
Arista introduced its optical line system for 400G, Arista OSFP-LS, which is a highly
compact, low power and cost effective solution for increasing bandwidth between
data centers without the need for external optical line systems. Arista continued to
expand the 7800R3 and 7280R3 Series with new models optimized for 400G and
100G with integrated security capabilities along with new power and density
optimized 7280R3 Series 10G and 25G systems to deliver enhancements for large
Enterprise and Service Providers.

Arista also announced a network observability software, DANZ Monitoring Fabric, on
Arista switching platforms for enterprise-wide traffic visibility and contextual insights
and an advanced security service, Attack Surface Assessment, through our
acquisition of Awake Security.

FISCAL 2020 EXECUTIVE COMPENSATION HIGHLIGHTS

As reflected in our general compensation philosophy and objectives, our executive compensation program is intended to
reward performance, attract and retain key personnel and increase stockholder value. In light of our financial performance
as described in the “Fiscal 2020 Business Highlights” section above, our fiscal 2020 executive compensation program
was intended to reward performance against our financial and key business objectives and incentivize successful
performance in these areas. Accordingly, our key executive compensation actions in fiscal 2020 advanced these
objectives:

• No Base Salary Increases—We did not increase
base salaries for our Named Executive Officers.

• Annual Bonuses Reflecting Pay for

Performance—As noted above, our financial
performance in fiscal 2020 achieved revenue of
approximately $2.32 billion a decrease of 3.9%
compared to fiscal 2019, and slightly below our
internal targets set at the beginning of the year. We
experienced strong sales to our enterprise and
other cloud and service provider customers, but this
was more than offset by reduced sales from our
larger cloud customers, combined with the impact
of some COVID-19 related supply constraints.

These financial results combined with significant
progress on business diversification and continued
excellence in product quality, innovation and

support, resulted in payments to our Named
Executive Officers under the 2020 Bonus Plan. Our
Chief Executive Officer declined a bonus for fiscal
2020.

• Equity Awards Promoting Our Stockholders’

Interests—Long-term equity incentives constitute a
significant majority of compensation paid to Named
Executive Officers in 2020. Long-term equity
incentives align the interests of executives with
those of our stockholders.

• Equity Awards Subject to Achievement—

Performance-based equity was implemented as an
important portion of our executive compensation
program for our Chief Executive Officer.

Subsequent to year end, we included performance-based equity as part of our executive compensation program for all
of our Named Executive Officers.

2021 PROXY STATEMENT

Executive Compensation

Effect of Most Recent Stockholder Advisory Vote on Executive
Compensation

Our compensation committee considers the results of the annual stockholder advisory vote on the compensation of our
Named Executive Officers and stockholder feedback on our executive compensation program as part of its annual
executive compensation review. At our 2020 annual meeting of stockholders, approximately 96.2% of the votes cast
approved the compensation program for our Named Executive Officers as described in our 2020 proxy statement. Based
on this strong stockholder support, our compensation committee determined not to make significant changes to our
existing executive compensation program and policies, except that our compensation committee added a performance-
based equity component to our executive compensation program in the form of performance-based restricted stock units
(“PRSUs”) for our Chief Executive Officer in 2020 and extended this performance-based equity component to all of our
other Named Executive Officers in 2021. Our compensation committee continues to evaluate the executive compensation
program and policies to determine the most appropriate ways of effecting our executive compensation philosophy and
objectives. Our compensation committee currently intends to continue to consider the results of the annual advisory vote
on executive compensation and stockholder feedback as data points in making executive compensation decisions.

Executive Compensation Philosophy and Objectives

We operate in a highly competitive business environment, which is characterized by frequent technological advances. To
successfully grow our business in this dynamic environment, we must continually develop and refine our products and
services to stay ahead of our competitors. To achieve these objectives, we need a highly talented and seasoned team of
technical, sales, marketing, operations, and other business professionals. We compete with other companies in our
industry and other technology companies in the Silicon Valley to attract and retain a skilled management team. To attract
and retain qualified executive candidates, our compensation committee recognizes that it needs to develop competitive
compensation packages. At the same time, our compensation committee is sensitive to the need to integrate new
Named Executive Officers into our executive compensation structure that we were seeking to develop, balancing both
competitive and internal equity considerations. To meet this challenge, we have embraced a compensation philosophy of
offering our Named Executive Officers a competitive total compensation program, which we view as the sum of base
salary, cash performance-based incentives, equity compensation and employee benefits, each of which recognizes and
rewards individual performance and contributions to our success, allowing us to attract, retain, and motivate talented
executives with the skills and abilities needed to drive our desired business results.

The specific objectives of our executive compensation program are to:

• reward the successful achievement of our financial

• recognize strong performers by offering cash

growth objectives;

• drive the development of a successful and profitable

business;

• attract, motivate, reward, and retain highly qualified

executives who are important to our success;

performance-based incentive compensation and
equity awards that have the potential to reward
individual achievement as well as contributions to
our overall success; and

• create value for our stockholders.

COMPENSATION PROGRAM DESIGN

Our executive compensation program for fiscal 2020 reflected our stage of development as a growing publicly-traded
company. Accordingly, the compensation of our Named Executive Officers consisted of base salary, a short-term cash
incentive compensation opportunity, long-term equity compensation in the form of PRSUs for our Chief Executive Officer
and time-based restricted stock units (“RSUs”) for our other Named Executive Officers, and certain employee health and
welfare benefits.

We offer cash compensation in the form of base salaries and cash incentive compensation opportunities with an annual
payment component. Typically, we have structured our annual cash incentive compensation opportunities to focus on the
achievement of specific short-term financial and operational objectives that will further our longer-term growth objectives.

37

Executive Compensation

Additionally, equity awards for shares of our common stock serve as a key component of our executive compensation
program. For 2020, we granted (i) PRSUs (which become eligible to vest only if the threshold performance is achieved) to
our Chief Executive Officer and (ii) RSUs (which provide certain value to recipients and limit dilution to our stockholders) to
our other Named Executive Officers. In the future, we may introduce other forms of equity awards, as we deem
appropriate, into our executive compensation program to offer our Named Executive Officers additional types of long-
term incentive compensation that further the objective of aligning the recipient’s interests with those of our stockholders.

Finally, we offer executives standard health and welfare benefits that are generally available to our other employees,
including medical, dental, vision, flexible spending accounts, life insurance and 401(k) plans.

We have not adopted any formal policies or guidelines for allocating compensation between current and long-term
compensation or between cash and non-cash compensation, although we use competitive market data to understand
the competitive market framework for pay mix. Within this overall framework, our compensation committee reviews each
component of executive compensation separately and also takes into consideration the value of each Named Executive
Officer’s compensation package as a whole and its relative value in comparison to our other Named Executive Officers.

Our compensation committee evaluates our compensation philosophy and executive compensation program as
circumstances require, and reviews executive compensation annually. As part of this review, we expect that our
compensation committee will apply our philosophy and the objectives outlined above, together with consideration for the
levels of compensation that we would be willing to pay to ensure that our executive compensation remains competitive
and that we meet our retention objectives, as well as the cost to us if we were required to find a replacement for a key
executive officer.

COMPENSATION-SETTING PROCESS

Role of our Compensation Committee

Compensation decisions for our executives are made by our compensation committee. Currently, our compensation
committee is responsible for reviewing, evaluating and approving the compensation arrangements, plans, policies, and
practices for our Named Executive Officers and overseeing and administering our cash-based and equity-based
compensation plans.

Each fiscal year, our compensation committee, after consulting with our management team and its compensation
consultant, establishes our corporate performance objectives and makes decisions with respect to any base salary
adjustment, and approves the corporate performance objectives and target annual cash incentive compensation
opportunities and equity awards for our executive officers, including our Named Executive Officers, for the upcoming fiscal
year. With respect to (i) our cash incentive compensation plan, (ii) the performance-based equity grant to our Chief
Executive Officer in 2020, and (iii) the performance-based equity to all of our Named Executive Officers in 2021, our
compensation committee determines the applicable goals for each corporate performance objective used for the
applicable year.

Our compensation committee reviews our executive compensation program from time to time, including any incentive
compensation plans, to determine whether they are appropriate, properly coordinated, and achieve their intended
purposes, and to make any modifications to existing plans and arrangements or to adopt new plans or arrangements.

Role of Management

In carrying out its responsibilities, our compensation committee works with members of our management team, including
our Chief Executive Officer and our Vice President, Global Human Resources. Typically, our management team (together
with our compensation consultant) assists our compensation committee in the execution of its responsibilities by
providing information on corporate and individual performance, market data, and management’s perspective and
recommendations on compensation matters.

Typically, except with respect to her own compensation, our Chief Executive Officer will make recommendations to our
compensation committee regarding compensation matters, including the compensation of our executive officers. Our
Chief Executive Officer also participates in meetings of our compensation committee, except with respect to discussions
involving her own compensation in which case she leaves the meeting.

38

2021 PROXY STATEMENT

Executive Compensation

While our compensation committee solicits the recommendations and proposals of our Chief Executive Officer with
respect to compensation-related matters, these recommendations and proposals are only one factor in our
compensation committee’s decision-making process.

Role of Compensation Consultant

Our compensation committee is authorized to retain the services of one or more executive compensation advisors from
time to time, as it sees fit, in connection with carrying out its duties.

In fiscal 2020, our compensation committee continued to engage Radford, a national compensation consulting firm, to
assist us in executing our executive compensation strategy and guiding principles, assessing current executive total
compensation levels against competitive market practices, developing a compensation peer group and advising on
potential executive compensation decisions for fiscal 2020. Our compensation committee provided Radford with
instructions regarding the goals of our executive compensation program and the parameters of the competitive review of
executive officer compensation packages that it was to conduct. In particular, the compensation committee instructed
Radford to analyze whether the compensation packages of our executive officers were consistent with our compensation
philosophy and competitive relative to market comparables. The compensation committee further instructed Radford to
evaluate the following components to assist the compensation committee in establishing fiscal 2020 compensation: base
salary; target and actual annual incentive compensation; target and actual total cash compensation (base salary and
annual incentive compensation); long-term incentive compensation (equity awards); target and actual total direct
compensation (base salary, annual incentive compensation and long-term incentive compensation); and beneficial
ownership of our common stock.

Radford does not provide any services to us other than the services provided to our compensation committee. Our
compensation committee has assessed the independence of Radford taking into account, among other things, the
factors set forth in Exchange Act Rule 10C-1 and the listing standards of the New York Stock Exchange, and has
concluded that no conflict of interest exists with respect to the work that Radford performs for our compensation
committee.

Use of Competitive Data

To assess the competitiveness of our executive compensation program and to assist in setting compensation levels,
Radford provided market data for the compensation peer group approved by our compensation committee.

Competitive Positioning

In fiscal 2020, our compensation committee continued to compare and analyze our executive compensation program
with that of a formal compensation peer group of companies.

In fiscal 2020, our compensation committee reviewed our executive compensation peer group, highlighting potential
outliers in the existing group and considering a broader screen of the technology market. In considering an updated peer
group, our compensation committee considered the following criteria: (i) companies in the computer networking,
communication products/services and software sectors with a focus on growing technology companies; (ii) companies
with revenues between $1 billion to $5.5 billion (approximately 0.5x to 2.5x of our then-current trailing 12-month revenue);
and (iii) companies with market capitalization generally between $6 and $40 billion (approximately 0.3x to 2x of our then-
current market capitalization). As a result, the following group was our executive compensation peer group for fiscal 2020
compensatory decisions made prior to July 20, 2020:

With respect to fiscal 2020 executive compensation decisions made on and following July 20, 2020, our compensation
committee reconsidered the peer group, highlighting potential outliers in the existing group and adjusting for changes in
our market capitalization. In considering an updated peer group, our compensation committee considered the following
criteria: (i) companies in the computer networking, communication products/services and software sectors with a focus
on growing technology companies; (ii) companies with revenues between $1 billion to $5.5 billion (approximately 0.5x to
2.5x of our then-current trailing 12-month revenue); and (iii) companies with market capitalization generally between $5
and $35 billion (approximately 0.3x to 2x of our then-current market capitalization). As a result, the following group was
our executive compensation peer group for fiscal 2020 compensatory decisions made on and following July 20, 2020:

For 2020, the portion of our Named Executive Officers’ actual total direct compensation (which consists of the base
salaries and annual cash incentive plan compensation paid to our Named Executive Officers with respect to 2020 and the
grant-date fair values of the equity awards granted to our Named Executive Officers in 2020, with each such value

2021 PROXY STATEMENT

Executive Compensation

The following describes each component of our executive compensation program, the rationale for each, and how the
compensation amounts and awards were determined for fiscal 2020.

Base Salary. Base salary is the primary fixed component of our executive compensation program. We use base salary to
compensate our Named Executive Officers for services rendered during the fiscal year and to ensure that we remain
competitive in attracting and retaining executive talent.

Our compensation committee reviews the base salaries of each Named Executive Officer annually and makes
adjustments as it determines to be reasonable and necessary to reflect the scope of a Named Executive Officer’s
performance, contributions, responsibilities, experience, prior salary level, position (in the case of a promotion), and
market conditions. We typically establish the initial base salary of a Named Executive Officer through arm’s-length
negotiation at the time, after taking into consideration his or her position, qualifications, experience, salary expectations,
and the base salaries of our other executives.

For fiscal 2020, our compensation committee determined not to make any changes to the base salaries of our Named
Executive Officers (which were generally below the market 25th percentile in our compensation peer group) as it thought
the base salary levels continued to be appropriate.

Our Named Executive Officers’ base salaries for fiscal 2020 were as follows:

Annual Cash Incentive Compensation; 2020 Bonus Plan

We use cash incentive compensation under our omnibus Employee Incentive Plan to motivate our executive officers,
including our Named Executive Officers, to achieve our annual financial and key operational objectives, while making
progress towards our longer-term strategic goals. Each fiscal year, our compensation committee sets the terms and
conditions of the Employee Incentive Plan for that fiscal year, which identifies the plan participants and establishes the
target cash incentive opportunity for each participant, the performance measures to be used to determine whether to
make payouts related to the fiscal year and the associated target levels for each measure, and the potential payouts
based on actual performance for the fiscal year. Typically, cash incentive payouts have been determined after the end of
the applicable performance period based on our performance against one or more financial and operational performance
objectives for the performance period as set forth in our annual operating plan.

In February 2020, our compensation committee set the terms and conditions of the Employee Incentive Plan for fiscal
2020 (the “2020 Bonus Plan”). The 2020 Bonus Plan included financial performance metrics for revenue and non-GAAP
operating income for the year. These two financial metrics determine the funding of the overall bonus pool available for
distribution. No payout would be made under the plan if achievement of the revenue metric was below 85% of target.

Once the overall funding level of the 2020 Bonus Plan was determined as outlined above, our compensation committee
would evaluate performance for each of our Named Executive Officers. In determining the payout for each Named
Executive Officer, our compensation committee would consider factors including: (A) contribution of the individual to the
achievement of the quantitative financial measures set forth above regarding the funding of the overall bonus pool;
(B) achievement against additional objectives related to the future growth of our business, including ability to diversify and
deliver in new markets; (C) consistent execution on product quality, innovation and support; and (D) overall individual
performance. The 2020 Bonus Plan provided for a single annual payout to each participant following the end of fiscal
2020 after our compensation committee evaluated corporate and individual performance as outlined above.

For purposes of our 2020 Bonus Plan, we define revenue in accordance with GAAP, and non-GAAP operating income as
GAAP operating income, less stock-based compensation expenses, other non-recurring items, one time acquisition
related costs and the amortization of intangible assets. A reconciliation of the non-GAAP financial metrics to the related

41

Executive Compensation

GAAP financial measure is set forth in our quarterly and annual press release announcing our financial results for the
fourth quarter and fiscal 2020.

Our compensation committee approved the following preliminary targets for the 2020 annual cash incentive
compensation of our Named Executive Officers (which provided each of our Named Executive Officers with target total
cash compensation at or around the market 25th percentile in our compensation peer group). For our Chief Executive
Officer, this target was 100% of base salary, while the targets for our other Named Executive Officers was 60% of base
salary. These targets are not strict targets and merely inform the aggregate of bonuses that will be accrued for financial
accounting purposes. Once a total incentive pool is accrued for all participants in the 2020 Bonus Plan, our compensation
committee looks at the performance for the year across the key metrics discussed above and factors in individual
performance and market comparable compensation in our peer group in determining a total incentive paid to each
Named Executive Officer.

For fiscal 2020, we achieved revenue of approximately $2.32 billion (a decrease of 3.9% from 2019, but below our plan
target by approximately 8.2%). In addition, we achieved non-GAAP operating income of approximately $874.8 million (a
decrease of 5.2% from 2019 levels, and below our plan target by approximately 11.5%). Our Compensation Committee
considered our overall achievement against these key metrics and determined it was appropriate to fund the 2020 Bonus
Plan at an 80% level.

Following the funding of the 2020 Bonus Plan based on the financial metrics outlined above, our compensation
committee looked at performance with respect to the other key metrics including diversification and delivery into new
markets, product quality, innovation and support, and individual performance. Our compensation committee considered
that we made good progress with respect to diversification of our revenue base during the year, including the expansion
of our enterprise datacenter and campus businesses. Also, our compensation committee considered continued strong
execution on product quality, innovation and customer satisfaction and observed consistent product performance metrics
for the year.

Given our overall financial performance for the year and the significant progress made against our non-financial objectives
for the year combined with our compensation committee’s determination of individual performance for each of our Named
Executive Officers and including consideration of our total cash compensation being at or around the 25th percentile of
compensation of our peer group, the total payouts to our Named Executive Officers under the 2020 Bonus Plan were
made as set forth below. Our Chief Executive Officer declined her proposed bonus payout for 2020, given that we had
not achieved our financial targets for the year.

We use equity awards to incentivize and reward our executives (including our Named Executive Officers) for long-term
corporate performance based on the value of our common stock and, thereby, to align the interests of our executives
with those of our stockholders. We grant stock options covering shares of our common stock and full value awards for
shares of our common stock, or awards without a purchase price, such as RSU awards.

New hire, or initial, equity awards for our executives are established through arm’s-length negotiations at the time the
individual executive is hired. In making these awards, we consider, among other things, the prospective role and
responsibility of the individual executive, competitive factors, the expectations concerning the size of the equity award, the
cash compensation to be received by the executive, and the need to create a meaningful opportunity for reward
predicated on the creation of long-term stockholder value.

In addition, we grant equity awards to our executives when our compensation committee determines that such awards
are necessary or appropriate to recognize corporate and individual performance, in recognition of a promotion, or to

42

2021 PROXY STATEMENT

Executive Compensation

achieve our retention objectives. To date, we have not applied a rigid formula in determining the size of these equity
awards. Instead, our compensation committee has determined the size of such equity awards for an individual executive
after taking into consideration market data compiled from our compensation peer group, a compensation analysis
performed by Radford, the equity award recommendations of our Chief Executive Officer, the scope of an executive’s
performance, contributions, responsibilities, and experience, and the amount of equity compensation held by the
executive, including the current economic value of his outstanding unvested equity awards and the ability of this equity to
satisfy our retention objectives, market conditions, and internal equity considerations. In making its award decisions, our
compensation committee has exercised its judgment and discretion to set the size of each award at a level it considered
appropriate to create a meaningful opportunity for reward predicated on the creation of long-term stockholder value.
Equity awards to our named executive officers typically have multi-year vesting periods of four or more years.

2020 Performance-Based Awards

The equity award granted to our Chief Executive Officer was a performance-based award of PRSUs granted in February
2020. We granted the PRSUs to our Chief Executive Officer to incentivize her and drive stockholder value creation. The
table below describes the PRSUs granted to our Chief Executive Officer. The intended value was converted into a target
number of PRSUs using a 30-day average trading price in accordance with our standard practices.

The number of PRSUs determined based on actual achievement as described above became eligible to vest upon
determination of achievement. 25% of PRSUs that became eligible to vest on the first quarterly vesting date after the date
the level of achievement of the performance goals was determined, and the remainder of the PRSUs that become eligible
to vest will vest in equal quarterly installments over an additional 3 years.

For fiscal 2020, the minimum revenue goal was not achieved. Our non-GAAP operating income was $874.8 million,
above the threshold goal but below the target goal, resulting in 4,178 PRSUs becoming eligible to vest.

2020 Time-Based Awards

The equity awards granted in fiscal 2020 to our Named Executive Officers other than our Chief Executive Officer
consisted of RSUs. We granted these awards to ensure that these Named Executive Officers receive a base value
regardless of fluctuations in our stock price, while incentivizing stockholder growth to deliver greater value for the
Company and the Named Executive Officer. In determining the size of these awards, our compensation committee
considered market compensation data from our peer group, the unvested equity held by each of these Named Executive
Officers and the Named Executive Officer’s expected future contributions to the Company and towards growing
stockholder value. To promote retention, the awards vest in equal quarterly installments over a period of approximately 4
years from May 2021. In prior fiscal years, we provided equity compensation to our named executive officers in a mix of
options and RSUs. For fiscal 2020, our compensation committee adopted new equity grant guidelines providing for
grants of 100% RSUs as the most appropriate method to deliver certain value to recipients in this period.

WELFARE AND OTHER EMPLOYEE BENEFITS

We have established a tax-qualified Section 401(k) retirement plan for all employees who satisfy certain eligibility
requirements, including requirements relating to age and length of service. In 2020, we made matching contributions for
the contributions made to the 401(k) plan by our employees, including our Named Executive Officers. We intend for the
plan to qualify under Section 401(a) of the Internal Revenue Code (the “Code”), so that contributions by employees to the
plan, and income earned on plan contributions, are not taxable to employees until withdrawn from the plan.

In addition, we provide other benefits to our Named Executive Officers on the same basis as all of our full-time employees.
These benefits include standard health, vacation and other benefits offered to our employees.

PERQUISITES AND OTHER PERSONAL BENEFITS

We generally do not provide perquisites to our Named Executive Officers or other personal benefits beyond what is
provided to employees on a broad basis.

Executive Officer Employment Arrangements
JAYSHREE ULLAL OFFER LETTER

We have entered into an offer letter with Jayshree Ullal, our President and Chief Executive Officer, pursuant to which
Ms. Ullal is an at-will employee. Ms. Ullal’s current annual base salary is $300,000 per year, and her target annual bonus
is targeted at $300,000. Ms. Ullal is also eligible to participate in all of our standard health, vacation and other benefits
offered to our employees.

ITA BRENNAN OFFER LETTER & SEVERANCE AGREEMENT

Ms. Brennan joined us as our new Chief Financial Officer in May 2015. We have entered into an offer letter with
Ms. Brennan that provides that she is an at-will employee. Ms. Brennan currently receives a base salary of $300,000 per
year, and her annual bonus is targeted at $180,000. Ms. Brennan is also eligible to participate in all of our standard
health, vacation and other benefits offered to our employees.

In addition, we entered into a severance agreement with Ms. Brennan, effective May 2015. The severance agreement
provides that if Ms. Brennan’s employment is involuntarily terminated other than for “cause” (as generally defined below)
or if Ms. Brennan resigns for “good reason” (as generally defined below) then, subject to her execution of a release of
claims, Ms. Brennan will receive continuing payments of her base salary for 12 months and accelerated vesting of time-
based equity awards that would have vested had Ms. Brennan remained employed with us for 12 months following her
termination of employment date. If the qualified termination of employment occurred during the period beginning on, and
for 12 months following a change in control, then the equity acceleration benefit would be 50% of the then-unvested
equity awards (and for any equity awards that vest based on the achievement of performance criteria, assuming the
performance criteria had been achieved at target levels for the relevant performance periods), if greater than the
acceleration benefit described in the previous sentence.

(1) Amount reported represents the grant-date fair value based upon target level of achievement. If maximum performance were deemed achieved for Ms. Ullal’s

performance-based restricted stock unit, the grant-date fair value of such award would be $9,050,535. Based on actual achievement for fiscal 2020, 4,178 PRSUs
became eligible to vest, and the balance of the PRSUs have already been forfeited. The fair value as of the grant date of those PRSUs that were not forfeited was
approximately $933,658.

(2) The amount reported for fiscal 2020 represents a patent bonus award and a spot bonus award paid by the Company to Mr. Duda.

(3) The amounts reported represent the aggregate grant-date fair value of the restricted stock units or stock options awarded to the Named Executive Officer, calculated in
accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 718 (“ASC Topic 718”). The assumptions used in calculating
the grant-date fair value of the stock options reported in this column are set forth in our audited consolidated financial statements included in our Annual Report on
Form 10-K, as filed with the SEC on February 19, 2021.

(4) The amounts reported for fiscal 2020 include matching contributions from the Company for the contributions made to the 401(k) plan by the Named Executive Officer

and a life insurance premium paid on the Named Executive Officer’s behalf.

Risk Assessment and Compensation Practices
Our management assesses and discusses with our compensation committee our compensation policies and practices for
our employees as they relate to our risk management, and based upon this assessment, we believe that, for the following
reasons, any risks arising from such policies and practices are not reasonably likely to have a material adverse effect on
us in the future:

• Our annual bonus plan considers a multiple of

• Our equity awards include multi-year vesting schedules

performance factors and allows our compensation
committee to review performance on a holistic basis
minimizing risk related to our short-term variable
compensation; and

requiring a long-term employee commitment.

Other Compensation Policies
Stock Ownership Guidelines. In April 2019, our board of directors adopted stock ownership guidelines. Our stock
ownership guidelines are designed to encourage our directors and our chief executive officer to achieve and maintain a
meaningful equity stake in our Company and more closely align their interests with those of our stockholders. The
guidelines provide that our chief executive officer should accumulate and hold, within five years from the later of the date
of the adoption of the stock ownership guidelines or the date such chief executive officer became chief executive officer,
an investment level in our common stock of three times the chief executive officer’s annual base salary.

51

Executive Compensation

Clawback Policy. In April 2019, our compensation committee adopted a Clawback Policy that permits the Company to
seek the recovery of both cash and equity compensation from an executive officer if: (i) the Company restates its financial
statements as a result of a material error; (ii) the amount of cash incentive compensation or performance-based equity
compensation that was paid that was determined based on achievement of specific financial results paid to the executive
officer would have been less if the financial statements had been correct; (iii) no more than three years have elapsed since
the original filing date of the financial statements upon which the incentive compensation was determined; and (iv) the
compensation committee determines that gross negligence, fraud or intentional misconduct by such executive officer
caused the material error.

Hedging or Pledging Policies. Our insider trading policy prohibits our directors, officers, employees and agents from
engaging in transactions in publicly-traded options, such as puts and calls, and other derivative securities with respect to
the Company’s securities. This prohibition extends to any hedging or similar transaction designed to decrease the risks
associated with holding Company securities. Stock options, stock appreciation rights and other securities issued
pursuant to Company benefit plans or other compensatory arrangements with the Company are not subject to this
prohibition.

These policies were established in part because transactions in derivative securities may reflect a short term and
speculative interest in the Company’s securities and may create the appearance of impropriety, even where a transaction
does not involve trading on inside information. Trading in derivatives may also focus attention on short-term performance
at the expense of the Company’s long-term objectives. In addition, the application of securities laws to derivatives
transactions can be complex, and persons engaging in derivatives transactions run an increased risk of violating securities
laws.

In addition, our insider trading policy prohibits certain executive officers from pledging the Company’s securities as
collateral for loans. Short sales with respect to the Company’s securities are prohibited under our policy.

Tax and Accounting Considerations

Deductibility of Executive Compensation. Section 162(m) of the Code generally disallows public companies a tax
deduction for federal income tax purposes of remuneration in excess of $1 million paid to the Chief Executive Officer and
certain other highly compensated executive officers.

Our compensation committee may consider the deductibility of compensation when making decisions, but may authorize
the payment of compensation that is not deductible when it believes it appropriate.

Taxation of “Parachute” Payments. Sections 280G and 4999 of the Code provide that executive officers and directors
who hold significant equity interests and certain other service providers may be subject to significant additional taxes if
they receive payments or benefits in connection with a change in control that exceeds certain prescribed limits and that
we (or a successor) may forfeit a deduction on the amounts subject to this additional tax. We did not provide any of our
Named Executive Officers with a “gross-up” or other reimbursement payment for any tax liability that the Named
Executive Officer might owe as a result of the application of Sections 280G or 4999, and we have not agreed and are not
otherwise obligated to provide any Named Executive Officer with such a “gross-up” or other reimbursement.

Accounting for Share-Based Compensation. We follow ASC Topic 718 for our share-based compensation awards.
ASC Topic 718 requires companies to measure the compensation expense for all share-based compensation awards
made to employees and directors, including stock options, based on the grant date “fair value” of these awards. This
calculation is performed for accounting purposes and reported in the compensation tables below, even though our
Named Executive Officers may never realize any value from their awards. ASC Topic 718 also requires companies to
recognize the compensation cost of their share-based compensation awards in their income statements over the period
that an executive officer is required to render service in exchange for the option or other award.

2021 PROXY STATEMENT

Executive Compensation

CEO Pay Ratio

As required by Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the
annual total compensation of our employees and the annual total compensation of our Chief Executive Officer:

For 2020, our last completed fiscal year:

• the median of the annual total compensation of all
employees of our Company (other than our Chief
Executive Officer), was $193,223; and

• the annual total compensation of our Chief Executive

Officer, as reported in the Fiscal 2020 Summary
Compensation Table presented elsewhere in this proxy
statement, was $6,342,972.

Based on this information, for 2020, the ratio of the annual total compensation of our Chief Executive Officer to the
median of the annual total compensation of all employees was approximately 33 to 1. This pay ratio is a reasonable
estimate based on our reasonable judgement and assumptions and calculated in a manner consistent with Item 402(u) of
Regulation S-K. SEC rules do not specify a single methodology for identification of the median employee or calculation of
the pay ratio, and other companies may use assumptions and methodologies that are different from those used by us in
calculating their pay ratio. Accordingly, the pay ratio disclosed by other companies may not be comparable to the
Company’s pay ratio as disclosed above.

Consistent with Item 402(u) of Regulation S-K, our Chief Executive Officer’s annual total compensation for the purposes
of the pay ratio is as presented in our Fiscal 2020 Summary Compensation Table. Importantly, that includes the grant-
date fair value based upon target level of achievement of the 27,000 PRSUs granted to our Chief Executive Officer in
February 2020. The grant-date fair value of those PRSUs was $6,033,690. However, as noted in our Fiscal 2020
Summary Compensation Table, only 4,178 of those PRSUs became eligible to vest as a result of performance in 2020
against the established performance metrics. The balance of the PRSUs have already been forfeited. The fair value as of
the grant date of those PRSUs that were not forfeited was approximately $933,658.

To identify the median of the annual total compensation of all our employees, as well as to determine the annual total
compensation of the “median employee,” the methodology and the material assumptions, adjustments, and estimates
that we used were as follows:

• We selected October 31, 2020 as the date upon which

o We did not apply any de minimis exclusions to

we would identify the median employee.

• To identify the “median employee” from our employee
population we used payroll and equity plan records.

o The compensation measure included the following:
annual base salary for salaried employees (or hourly
rate multiplied by estimated work schedule for
hourly employees), actual incentive compensation
paid in 2020 as of the determination date, and grant
date fair value of equity awards granted in 2020.

remove certain employees in non-U.S. jurisdictions
allowed by Item 402(u).

o Amounts paid in foreign currency were converted
into United States dollars using 2020 average
exchange rates.

o The calculation was performed for all employees,
excluding Ms. Ullal, whether employed on a full-
time, part-time, or seasonal basis. Because there
was an even number of employees, two individuals
were identified as the median. We selected the
employee with the longest tenure as that employee
was a better representative of the median
compensation.

With respect to the annual total compensation of the “median employee,” we identified and calculated the elements of
such employee’s compensation for 2020 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K,
resulting in annual total compensation of $193,223.

With respect to the annual total compensation for our Chief Executive Officer, we used the amount reported in the “Total”
column of our Summary Compensation Table for Fiscal Year 2020.

April 8, 2021 for:

• each of our directors and nominees for director;

• all of our current directors and executive officers as a

• each of our Named Executive Officers;

group; and

• each person or group, who beneficially owned more

than 5% of our common stock.

We have determined beneficial ownership in accordance with the rules of the SEC, and thus it represents sole or shared
voting or investment power with respect to our securities. Unless otherwise indicated below, to our knowledge, the
persons and entities named in the table have sole voting and sole investment power with respect to all shares that they
beneficially owned, subject to community property laws where applicable.

We have based our calculation of the percentage of beneficial ownership on 76,271,362 shares of our common stock
outstanding as of April 8, 2021. We have deemed shares of our common stock subject to stock options that are currently
exercisable or exercisable within 60 days of April 8, 2021 and RSUs that vest within 60 days of April 8, 2021, which are
subject to vesting conditions expected to occur to be outstanding and to be beneficially owned by the person holding the
stock option for the purpose of computing the percentage ownership of that person. We did not deem these shares
outstanding, however, for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Arista Networks, Inc.,
5453 Great America Parkway, Santa Clara, California 95054. The information provided in the table is based on our

2021 PROXY STATEMENT

DELINQUENT SECTION 16(A) REPORTS

Section 16(a) of the Exchange Act requires our directors, executive officers and holders of more than 10% of Arista Networks
common stock to file with the SEC reports regarding their ownership and changes in ownership of our securities, and to furnish
copies of such reports to the Company. As a matter of practice, we assist our officers and directors in preparing initial
ownership reports and reporting ownership changes, and typically file those reports on their behalf. Based solely on our review
of such forms in our possession and the representations of our officers and directors, we believe that during 2020, all
Section 16(a) filing requirements were satisfied, except that a Form 4 filed on December 15, 2020 reporting the exercise and
sale of 1,375 shares of common stock by Ms. Ullal was inadvertently filed late due to an administrative error.

RELATED PERSON TRANSACTIONS

In addition to the compensation arrangements, including employment, termination of employment and change in control
arrangements discussed above in the sections titled “Board of Directors and Corporate Governance—Director
Compensation” and “Executive Compensation,” we describe below transactions and series of similar transactions, since
the beginning of our last fiscal year, to which we were a party or will be a party, in which:

• the amounts involved exceeded or will exceed

$120,000; and

• any of our directors, nominees for director, executive

officers or holders of more than 5% of our outstanding
capital stock,

or any immediate family member of, or person sharing
the household with, any of these individuals or entities,
had or will have a direct or indirect material interest.

Other than as described below, there has not been, nor is there any currently proposed, transactions or series of similar
transactions to which we have been or will be a party.

Investors’ Rights Agreement

We are party to an investors’ rights agreement which provides, among other things, that certain holders of our common
stock have the right to demand that we file a registration statement or request that their shares of our common stock be
covered by a registration statement that we are otherwise filing.

Other Transactions

Charles Giancarlo, a member of our board of directors, also serves as chief executive officer and a member of the board
of directors of Pure Storage, Inc., a data storage solutions company, since August 2017. Pure Storage, Inc. has
purchased, and may purchase from time to time, our products in the ordinary course of business and we have also
purchased, and may purchase from time to time, products from Pure Storage in the ordinary course of business
(collectively, the “Pure Storage Transactions”). Mr. Giancarlo did not participate in negotiations involving, and does not
have a direct or indirect material interest in, these transactions. Our audit committee has established certain guidelines to
pre-approve the Pure Storage Transactions, subject to the review by our audit committee at each regularly scheduled
audit committee meeting that such Pure Storage Transactions complied with such guidelines.

We have granted stock options and restricted stock units to our Named Executive Officers and certain of our directors.
See the section titled “Executive Compensation—Outstanding Equity Awards at 2020 Year-End” for a description of these
stock options and restricted stock units. In the ordinary course of business, we enter into offer letters and employment
agreements with our executive officers. We have also entered into indemnification agreements with each of our directors
and officers. The indemnification agreements and our certificate of incorporation and bylaws require us to indemnify our
directors and officers to the fullest extent permitted by Delaware law.

57

Other than as described above under this section titled “Related Person Transactions,” since January 1, 2020, we have
not entered into any transactions, nor are there any currently proposed transactions, between us and a related party
where the amount involved exceeds, or would exceed, $120,000, and in which any related person had or will have a
direct or indirect material interest. We believe the terms of the transactions described above were comparable to terms
we could have obtained in arm’s-length dealings with unrelated third parties.

Policies and Procedures for Related Party Transactions

Our audit committee has the primary responsibility for reviewing and approving or ratifying related party transactions. We
have a formal written policy providing that a related party transaction is any transaction between us and an executive
officer, director, nominee for director, beneficial owner of more than 5% of any class of our capital stock, or any member
of the immediate family of any of the foregoing persons, in which such party has a direct or indirect material interest and
the aggregate amount involved exceeds $120,000. In reviewing any related party transaction, our audit committee is to
consider the relevant facts and circumstances available to our audit committee, including, whether the transaction is on
terms no less favorable than terms generally available to an unaffiliated third party under the same or similar
circumstances, and the extent of the related party’s interest in the transaction. Our audit committee has determined that
certain transactions will be deemed to be pre-approved by our audit committee, including certain executive officer and
director compensation, transactions with another company at which a related party’s only relationship is as a
non-executive employee, director or beneficial owner of less than 10% of that company’s shares, transactions where a
related party’s interest arises solely from the ownership of our common stock and all holders of our common stock
received the same benefit on a pro rata basis, and transactions available to all employees generally. If advance approval
of a transaction is not feasible, the Chair of our audit committee may approve the transaction and the transaction may be
ratified by our audit committee in accordance with our formal written policy.

OTHER MATTERS

Householding

We have adopted a procedure called “householding,” which the SEC has approved. Under this procedure, stockholders
of record who have the same address and last name and have not previously requested electronic delivery of proxy
materials will receive a single envelope containing the Notices for all stockholders having that address. The Notice for
each stockholder will include that stockholder’s unique control number needed to vote his or her shares. This procedure
reduces our printing costs, mailing costs, and fees. Upon written or oral request, we will deliver promptly a separate copy
of the Notice and, if applicable, our proxy materials to any stockholder at a shared address to which we delivered a single
copy of any of these materials. To receive a separate copy, or, if a stockholder is receiving multiple copies, to request that
we only send a single copy of the Notice and, if applicable, our proxy materials, such stockholder may contact us at the
following phone number (408) 547-5500 or address:

Arista Networks, Inc.
Attention: Investor Relations
5453 Great America Parkway
Santa Clara, California 95054

Stockholders who beneficially own shares of our common stock held in street name may contact their brokerage firm,
bank, broker-dealer or other similar organization to request information about householding.

committee. Any such recommendations should include the nominee’s name and qualifications for membership on our
board of directors and should be directed to our Secretary at the address set forth above. For additional information
regarding stockholder recommendations for director candidates, see “Board of Directors and Corporate Governance—
Stockholder Recommendations for Nominations to the Board of Directors.”

In addition, our amended and restated bylaws permit stockholders to nominate directors for election at an annual meeting of
stockholders. To nominate a director, the stockholder must provide the information required by our amended and restated
bylaws. In addition, the stockholder must give timely notice to our Secretary in accordance with our amended and restated
bylaws, which, in general, require that the notice be received by our Secretary within the time period described above under
“Stockholder Proposals” for stockholder proposals that are not intended to be included in a proxy statement.

Availability of Bylaws

You may contact our Secretary at our principal executive offices for a copy of the relevant bylaw provisions regarding the
requirements for making stockholder proposals and nominating director candidates.

Fiscal Year 2020 Annual Report and SEC Filings

Our financial statements for our fiscal year ended December 31, 2020 are included in our Annual Report on Form 10-K, which

Item 1. Business

PART I

Arista Networks pioneered software-driven, cognitive cloud networking for large-scale data center and
campus workspace environments. Our cloud networking solutions consist of our Extensible Operating System
("EOS"), a set of network applications and our Ethernet switching and routing platforms. Our cloud networking
solutions deliver industryt
-leading performance, scalability, availability, programmability, automation and
visibility.

In recent years, we have sought to bring the operational consistency and principles of cloud networking
to the broader enterprise and campus markets with our Cognitive Cloud Networking approach. Our cognitive
single-tier SplineTM campus network extends EOS across the campus workspace and the data center.
In
addition, we acquiqq red Mojoo Networks, Inc. (“Mojoo ”), the inventor of Cognitive WiFiTM to extend these same
cognitive principles to the wireless network. CloudVision®, our network-wide approach for workload
orchestration and automation, leverages EOS and Cognitive WiFiTM features, to deliver a turnkey workflow
orchestration and automation solution for cloud networking to our enterprr

ise customers.

In the early part of 2020, we acquired Big Switch Networks, a pioneer in network monitoring softwa

re.
These Big Switch capaa bilities, integrated with the Arista switching portfolff
io, power the DANZ Monitoring
Fabric (DMF), a leading network monitoring solution. We also completed the acquiqq sition of Awake Security, an
AI-driven network detection and response (NDR) security company, at the end of 2020. We believe the
combination of DMF and Awake Security capaaa bilities delivers the next generation of operationally effiff cient
network security and visibility.

ff

In addition, we continued to expand our data center and campa

us network producdd t portfolio duriuu ng 2020
including the introduction of the 750 Series modular chassis, a modular campus PoE switch that delivers high
perforff marr

nce, security, visibility and power network security and visibility.

Since we began shipping our producdd ts, we haveaa

grown rapidly, and, according to market research, we
have achieved the second largest market share in data center Ethernet switch ports and revenue, excluding
China. We have been profitff able and cash flow positive for each year since 2010.

We sell our producdd ts through both our direct sales force and our channel partners. Our end customers
span a range of industries and include large internet companies, service providers, financial services
organizations, government agencies, media and entertainment companies and others. Our customers include six
of the largest cloud services providers based on annual revenue.

Our Market Opportunity

We compete primarily in the data center switching market for 10 Gigabit Ethet

rnet and above,
excluding blade switches. We added advadd nced routing capabilities to our R-Series switches, which in addition to
switching address the Data Center Interconnect (DCI) markeaa
t and parts of the wide area networking routing
market. We more recently began to compete in the enterprise campus market for 1 Gigabit Ethernet switching
and above and in the cloud-managed wireless networking market. In addition, our acquisitions of Big Switch
Networks and Awake Security enhance ouru ability to address a portion of the Network Monitoring and Network
Detection and Response (NDR) security markets.

We believe that cloud computing represents a fundamental shiftff

from traditional legacy network
architecturtt es. As organizations of all sizes have moved workloads to the cloud, spending on cloud and next-
generation data centers has increased rapia dly, while traditional legacy IT spending has grown more slowly.

Our Customers

As of December 31, 2020, we had delivered our cloud networking solutions to over 7000 end
customers worldwide. Our end customers span a range of industries and include large internet companies,
service providers, financial services organizations, government agencies, media and entertainment companies
and others. For the years ended December 31, 2020, 2019 and 2018, purchases by Microsoftff accounted for more
than 10% of our total revenue.

Cloud Networking and Digital Transforff mation Market Drivers

Digital

transforff mation is funda

u mentally changing the way IT infrastructure is built and how
applications are delivered from a cloud environment. In cloud computing, applications are distritt buted across
r, form a pool
thousands of servers. These servers are connected with high-speed network switches that, togethet
of resources that allows applications to be rapidly deployed and cost-effecff
tively updated. Cloud computing
enables ubiquitous and on-demand network access to these applications from internet-connected devices
including personal computers, tablets, IoT (Internet of Things) devices, and smartpht ones.

Nearly all consumer applications today are delivered as cloud services. Enterprise applications are
rapia dly moving to the cloud as well since cloud services are easier and more cost effecff
tive to deploy,yy scale and
operate than traditional applications. Internet leaders like Amazon, Facebook, Google, and Microsoft pioneered
the development of large-scale cloud data centers in order to meet the growing demands of their users, including
business customers. Enterprises and service providers around the world are adopting cloud computing
technologies in order to achieve similar performa

nce imprm ovements and cost reductions.

ff

The aggregate network bandwidth in the cloud can be orders of magnitudtt

e higher than typical legacy
data center networks. Thereforff e, the networks in such cloud environments must be architected and built in a
new way. We refer to these next-generation data center networks as cloud networksrr
. Cloud networksrr must
deliver high capacity,yy high availability and predictable performance, and must be programmable to allow
integration with third-party applications for network, management, automation, orchestration and network
services.

The much larger scale of cloud networks requires much higher network availability since network outages
in the cloud are costly to customers. Traditional network switches have evolved, and the features and capaaa bia lities of
their operating system have expanded over many years without
addressing the structural deficiencies of their
underlying softwa

, making it difficff ult to achieve high network switch reliability.

re architecturesu

ff

t

Some networking vendors have built products that use proprietary protocols to address the scaling needs of
next-generation data centers. However, proprietary protocols are generally disfavff ored by internet companies or
cloud service providers because they create vendor lock-in.

Legacy enterprr

ise networks are generally not programmabla e and, as a result, are extremely diffiff cult to
integrate with third-party applications for network management, automation, orchestration and network services.
This lack of integration forces customers to continue to rely on time consuming, error-prone manual processes that
may be cost-prohibitive.

Traditional enterprise wired and wireless campus networks must cope witht an ever-increasing number of
endpoint IoT (Internet of Things) devices for users to be connected anywhere. Campus admid
ors have sought to
address the resulting increased network complexities and bottlenecks through the adoption of a myriad of platforms,
operating systems, proprietary features and network management tools. Coupled with the explosive growth of IoT
and the requirement for workloads, the operational costs of managing these complexities have become prohibitive.

modular and reliable. The programmability of EOS has allowed us to expand our software applications to address
the ever increasing demands of cloud networking, including workflow automation, network visibility, analytics and
network detection and response, and has furthett

servers and millions of virtual machines with the least number of switching tiers. We achieve this by leveraging
standard protocols to meet the scale requirements of cloud computing. We have used active-active Layer 2 and
Layer 3 network topologies to enable customers to build extremely large and resilient networks.

High Availability

Our highly modular EOS software architecture was designed to be fault-isolating and self-hff ealing in order
to deliver higher availability compared to legacy network operating systems. In addition, our customers can non-
disruptively upgrade our switches running in the network using our Smart System Upgrade, or SSU application,
without interruptuu ing the network service.

Macro-Segmentation Services (MSSTM) is one of the services enabled via CloudVisVV ion. Since CloudVisioVV n
maintains a network-wide database of all states within the network, as well as direct integration with hypervisor
resources like VMware vSphere and NSX, Macro-Segmentation extends the concept of fine-grained inter-hypervisor

Our sales organization is supported by systems engineers with deep technical expertise and responsibility
for pre-sales technical support and solutions engineering for ouru end customers, systems integrators, original

Seasonality

Our rapida

historical growth may have reducdd ed the impact of seasonal or cyclical factors that might have
influenced our business to date. As our increasing size causes our growth rate to slow, seasonal or cyclical variations
in our operations may become more pronouncuu ed over time and may materially affeff ct our business, financial
condition, results of operations and prospects. We operate on a December 31st year end and have typically
experienced higher sequential producdd t revenue growth in the fourthtt quarter, followed by flat-to-declining sequential
growth in the first quarter of the following year. We believe that this seasonality results from a number of factors,
including the procurement, budgeting and deployment cycles of many of our end customers.

The markets in which we compete are highly competitive and characterized by rapia dly-changing

Intellectual Property

Our success and ability to compete depend substantially upon our core technology and intellectual property.
We rely on patent, trademark and copyright laws, trade secret protection and confidff entiality agreements with our
employees, end customers, resellers, systems integrators and others to protect our intellectual property rights. We
file U.S and foreign patent applications to protect our intellectual property and believe that the duration of our issued
patents is adequate relative to the expex cted lives of ouru products. Patents generally have a duration of twenty years
from filing. The remaining duration on the individual patents in our patent portfolio varies.

We cannot assure that any of our patent applications will result in the issuance of a patent or whether the
examination process will result in patents of valuable breadthdd
or applicability. In addition, any patents that mayaa be
issued may be contested, circumvented, found unenforceabla e or invalidated, and we may not be able to prevent third
parties from infringing them. We also license software from third parties for integration into our products, including
open source software and othet
r software available on commercially-reasonable terms. We own a number of
trademarks in the U.S. and other jurisdictions, including Arista, EOS, CloudVisioVV n, CloudStream, CVP, CVX,

re, technology and othet

Our industry is characterized by the existence of a large number of patents and frequent claims and related
litigation regarding patent and other intellectual propertytt
rights. If we become more successful, we believe that
competitors will be more likely to try to develop producdd ts that are similar to ours and that may infringe ouruu
proprietary rights. It may also be more likely that competitors or other third partaa ies will claim that our products
infringe their proprietary rights. In particular, large and establis
hed companies in our industry have extensive patent
portfolios and are regularly involved in both offeff nsive and defensive litigation. From time to time, third parties,
including certain of these large companiaa es and non-practicing entities, may assert patent, copyright, trademark and
othet
r intellectual property rights against us, our channel partaa ners or ouru end customers, whom our standard license
and other agreements obligate us to indemnifyff against such claims.

Risks Related to Our Business and Industry

The COVID-19 pandemic could materially adversely affeff ct our business, financial condition, results of
operations and prospects.

The COVID-19 pandemic has had and could continue to haveaa

an adverse impact on the business operations
of our company and our customers, partaa ners, manufacturtt ers, suppliers, distribution fulfilff lment centers and service
depots. To comply with the shelter in place orders and to safeguard our emplm oyees, we closed all of ouruu offiff ces,
with limited exceptions for essential employees in certain locations, and the vast majoa rity of our employees continuenn
to work from home.
In addition, we expex rienced, and may continue to experience, manufacturing and supply chain
disruptions and logistic challenges. Our contract manufacturers in Malaysia, Mexico and the United States are
aa mic and have expex rienced shelter in place orders, workforce disruptions and delays in
impacted by the pande
ting products. While our contract manufacturers have made significff ant progress, they may be
producdd tion and expor
subjeb ct to supply constraints. Similar to our manuf
ent centers and service depots
riu ng facilities, our direct fulfillmff
ff
continue to operate with varying degrees of governme
nt restriction on access, which can materially impact our
ability to ship products or provide support services to our customers. As a result of COVID-19 related
turiu ng disruptions, the lead times for our products have increased and our supply chain costs have increased
manufacff
which has adversely impam cted our gross margins. In addition, we have and may continue to purchase buffeff
r
supply to support long-
inventories of components and products that have extended lead times to ensure adequateaa
a
term customer demand, and this may increase the risk of future excess and obsolete inventory and could haveaa
negative impact on our gross margins.

actu
r

x

aa

As the COVID-19 pandemic continues, we haveaa

expex rienced and may continue to expex rience additional

risks including:

•

•

•

•

•

more manufacff

turing disruptions and supply shortages;

longer lead-times for component parts incorporated into our producdd ts;

reduced capaaa

citytt and output

tt

at factories and factory closures;

disruptions in logistics which impact the movement of components and finished producdd ts;

overall increased demand for materials which could result in a limited supply of materials and

components that are incorporated in ouruu products;

•
customers;

•

delays in product shipments and limits on our ability to provide in-person support services to

increased risk of future excess and obsolete inventory as we increase our inventory bufferff

s of long

lead time components to support longer term customer demand; and

•

further increased lead times for our products.

The COVID-19 pandemic could limit our ability to add new customers and cause sales disruptions, order
cancellations, longer upgrade cycles by customers for network equiqq pment and overall lower demand for ouru
productdd
s and services. Customers may purchase products in advance of their internal demand which could result in
lower purchases in subsequent quarters. We could face increased risk of customer defaulaa ts and delays in payment.

In addition, the COVID-19 pandemic has adversely affecff

ted, and may continue to adversely affeff ct, the
global economy and financaa
ial markets, which may result in an extended economic slowdown or a global recession
that could adversely impact our business. Due to the duration of the pandemic, the uncertainty around vaccination
deployment with respect to the COVID-19 pandemic, the uncertainty around the impam ct of new strains of COVID-
19 and uncertain timing of a global recovery,rr we are unable to predict the full impact of the COVID-19 pandemic on
our business operations and financial perforff mance.

The networking market is rapidly evolving. If this market does not evolve as we anticipate or our target end
customers do not adopt our networking solutions, we may not be able to compete effeff ctively,yy and our ability
.rr
to generate revenue will sufferff

A substantial portion of ouru business and revenue depends on the growth and evolution of the networking
market. The market demand for networking solutions has increased in recent years as end customers have deployed

16

larger, more sophisticated networks and have increased the use of virtualization and cloud computing. The continuenn d
growth of this market will be dependent upon many factors including but not limited to the adoption of and demand
for our end customers’ products and services, the expansion, evolution and build out of our end customers’ networks,
the capacity utilization of existing network infrastrutt cturtt es, changes in the technological requirements for the
producdd ts and services to be deployed in these networks, the amount and mix of capital spending by our end
customers, the development of network switches and cloud service solutions by our large end customers for internal
use, the financial performance and prospects of our end customers, the availability of capita

customers, changes in government regulation that could impact netwott

The markets in which we compete, including the markets for data center, campa

Seasonality may cause fluctuations in our revenue and results of operations.

We operate on a December 31st year end and have typically experienced higher sequential product revenue
growth in the fourth quarter, followed by flat to declining sequential growth in the first quarter of the following year.
We believe that this seasonality results from a number of factors, including the procurement, budgeting and
deployment cycles of many of our end customers. Ouru rapiaa d historical growth may haveaa
reduced the impam ct of
seasonal or cyclical factors that might have influenced our business to date. As our increasing size causes our growth
rate to slow, seasonal or cyclical variations in our operations may become more pronounced over time and may
materially affeff ct our business, financial condition, results of operations and prospects.

We are exposed to fluctuations in currency exchange rates, which could adversely affeff ct our business,
financial condition, results of operations and prospects.

Our sales contracts are primarily denominated in U.S. dollars, and thereforff e, substan

tially all of our revenue
is not subjecb
t to foreign currency risk. However, a strengthet ning U.S. dollar could increase the real cost of ouru
producdd ts to our end customers outside of the U.S., which could advedd rsely affeff ct our business, financial condition,
results of operations and prospects. In addition, a decrease in the value of the U.S. dollar relative to foreign
currencies could increase our product and operating costs in foreign locations. Further, a portion of our operating
expenses is incurred outside the U.S., is denominated in foreign currencies and is subject to fluctuations due to
hedge against the risks associated with
changes in foreign currency exchange rates. If we are not able to successfully

If we needed to raise additional capital to expand our operations, invest in new products or for other
corporate purposes, our failure to do so on favorable terms could reduce our ability to compete and could

We expect that our existing cash and cash equivalents, will be sufficff

ient to meet our anticipated cash needs
for the foreseeabla e future. If we did need to raise additional funds to expand our operations, invest in new products

If we raise additional equiqq ty financing, our stockholders may expex rience significant dilution of their ownership
interests, and the market price of our common stock could decline. Furthet
rmore, if we engage in debt financing, the
holders of such debt would haveaa
priority over the holders of common stock, and we may be required to accept terms
that restrict our ability to incuru additional indebtedness or impose other restrictions on ouruu business. We may also be
required to take other actions that would otherwise be in the interests of the debt holders, including maintaining
specified liquidity or other ratios, any of which could harm our business, financial condition, results of operations
and prospects. If we need additional capital and cannot raise it on acceptable terms, we may not be able to, among

organizations, acquire complementary technologies, producdd ts or businesses, and respond to competitive pressures or
unanticipated working capiaa tal requirements. Our failure to do any of these things could seriously harm our business,

We expect large purchases by a limited number of end customers to continue to represent a substantial
portion of our revenue, and any loss, delay,yy decline or other change in expected purchases could result in
material quarter-to-quarter fluctuations of our revenue or otherwise adversely affect our results of
operations.

Historically, large purchases by a relatively limited number of end customers have accounted for a
significant portion of our revenue. We have experienced unpredictability in the timing of orders from these large end
to these customers, the time it takes these end
customers primarily due to changes in demand patterns specificff
customers to evaluate, test, qualify and accept ouru products, and the overall complexity of these large orders. We
expect continued variaa ability in our customer concentration and timing of sales on a quarterly and annual basis. For
example, sales to our end customer Microsoft and Facebook in fiscal 2019 collectively represented 40% of our total
revenue, whereas sales to our end customer Microsoft in fiscal 2020 amounted to 21.5% of our revenues, with our
end customer Facebook representing less than 10% of our revenues in the period. These changes contributed to a
year-over-year decline in our revenue for fiscal 2020 compared to fiscal 2019. However, this decline in revenue was
offsff et in part by stronger sales to our enterprise and other cloud and service provider customers.
In addition, we
typically provide pricing discounts to large end customers, which may result in lower margins for the period in
which such sales occur.

As a consequence of the concentrated nature of our customer base and their purchu

asing behavior, ouru
quarterly revenue and results of operations may fluctuate from quartaa er to quarter and are difficff ult to estimate.
Changes in the business requirements or focus, upgrade cycles, vendor selection, project prioritization, manner in
which spending allocations are assigned among multiple vendors based upon specific network roles or projects,
financial prospects, lack of growth of our customers, capital
or purchasing behaviaa or and
deceleration in spending of our key end customers could significff antly decrease our sales to such end customers or
could lead to delays, reducdd tions or cancellations of planned purchases of our products or services. Moreover,rr
rwise
because our sales will be based primarily on purchase orders, our customers may cancel, delay, reduce or othet
modify their purchase commitments with little or no notice to us. This limited visibility regarding our end
customers’ product needs, the timing and quantaa ity of which could vary significff antly, requiqq res us to rely on estimated
demand forecasts to determine how much material to purchuu
ase and product to manufacture. Our failure to accurately
g current and future purchase
forecast demand can lead to product shortages which could lead to delays in fulfillin
orders that can impede production by our customers and harm our customer relationships. And, in the event of a
cancellation or reduction of an order, we mayaa not haveaa
enough time to reduce operating expenses to mitigate the
effecff

new or othet
purchases by our larger end customers witht purchases by new or existing end customers. These customers could

increase their adoption of "white box" solutions and open source network operating systems, demand pricing

spending levels. If these factors drove some of our large customers to cancel all or a portion of their business
relationships with us, the growtht
in our business and the ability to meet our current and long-term financial forecasts
may be materially impacted. We expect that such concentrated purchases will continue to contribute materially to
our revenue for the foreseeable future and that our results of operations may fluctuate mateaa rially as a result of such
larger end customers’ buying patterns. In addition, we may see consolidation of our customer base, such as among
Internet companiaa es and cloud service providers, which could result in loss of end customers. The loss of such end
customers, or a significff ant delay or reduction in their purchases, including reductions or delays due to customer
departurtt es from recent buying patterns, or an unfavff orable change in competitive conditions could materially harm
our business, financial condition, results of operations and prospects.

If we are unable to increase market awareness of our company and our new products and services, our
revenue may not continue to grow or may decline.

We have not yet established broad market awareness of our new products and services, including new

The sales prices for our producd ts and services may decline for a variety of reasons, including competitive

These orders are complex and difficff
ult to complete because prospective end customers generally consider a number
of factors over an extended period of time before committing to purchase the products and solutions we sell. End
customers, especially our large end customers, ofteff n view the purchase of our producdd ts as a significant and strat

decision and requiqq re considerable time to evaluate, test and qualifyff ouru products prior to making a purchase decision
and placing an order. The lengtht of time that end customers devote to their evaluation, contract negotiation and
budgeting processes varies significff antly. In addition, customers may delay upgrades to their network infrastructure
which extends the upgrade and sales cycle. Our products’ sales cycles can be lengthy in certain cases, especially
with respect to our prospective large end customers. During the sales cycle, we expend significff ant time and money
on sales and marketing activities and makeaa
investments in evaluation equipment, all of which lower our operating
margins, particularly if no sale occurs. Even if an end customer decides to purchase our products, there are many
factors affecff
ting the timing of our recognition of revenue, which makes our revenue difficff ult to forecast. For
example, there mayaa be unexpected delays in an end customer’s internal procurement processes, particularly for some
of our larger end customers for which ouru products represent a very small percentage of their total procurement
activity. In addition, due to the COVID-19 pandemic, the sales cycle may be extended and there may be delays and
reductions of expenditures and cancellations by end customers. There are many other factors specificff
to end
customers that contribute to the timing of their purchases and the variabilitytt of ouru revenue recognition, including
the strategic importance of a particular project to an end customer, budgetary constraints and changes in their
personnel.

Even after an end customer makes a purchase, there may be circumstances or terms relating to the purchase
that delay ouru ability to recognize revenue from that purchase. In addition, the significance and timing of our
producdd t enhancements, and the introduction of new products by our competitors, may also affect
end customers’
purchases. For all of these reasons, it is diffiff cult to predict whether a sale will be completed, the particular period in
which a sale will be completed or the period in which revenue from a sale will be recognized. If our sales cycles

In order to reduce manufactu

conditions such as international trade wars like the U.S. trade war with China and the impact of public health
epidemics like the COVID-19 pandemic. For example, in the past, we haveaa
experienced shortages in inventory for
dynamic rando

delayed our producdd tion and/or the release of our new producdd ts. We have also recently experienced shortages and
delays relating to certain components as a result of manufacturing and supply disruptuu ions due to the COVID-19
pandemic.

If we are unable to obtain sufficff

ient quantities of these components on commercially reasonable terms or in
a timely manner, or if we are unable to obtain alternative sources for these components, sales of our products could
be delayed or halted entirely or we may be required to redesign our products. Any of these events could result in lost

Our reliance on component suppliers also yields the potential for the infringement or misappropriation of

we do not receive indemnificff ation could require us to incur significff ant legal expenses in defending against such

Our product development effor

ts are also dependent upon the success of our continued collaboration with
our key merchant silicon vendors such as Broadcom and Intel. As we develop our product roadmap, we select
specific merchant silicon from these vendors for each new product. It is critical that we work in tandem with these
vendors to ensure that their silicon includes improved featurtt es, that our producdd ts take advadd ntage of such improved
featurtt es, and that such vendors are able to supply us with suffiff cient quantaa ities on commercially reasonablea
term to
meet customer demand. Reliance on these relationships allows us to focus our research and development resources
on our software core competencies while leveraging their investments and expertise. The merchant silicon vendors
may not be successful in continuing to innovate, meet deadlines for the release of their products or produce a
sufficff
ient supply of their products. Moreover, these vendors may not collaborate with us or may become
competitive with us by selling merchant silicon for “white boxes” or othett

not to seek patent protection for certain innovations and may choose not to pursue patent protection in certain
jurisdictions. Further, we do not know whether any of our pending patent applications will result in the issuance of
patents or whether the examination process will require us to narrow our claims. To the extent that additional patents
are issued from our patent applications, which is not certain, they may be contested, circumvented or invalidated in
the future. Moreover, the rights granted under any issued patents may not provide us with proprietary protection or
competitive advadd ntages, and, as with any technology, competitors may be able to develop similar or superior
technologies to our own now or in the future. In addition, we rely on confidff entialitytt or license agreements with third
parties in connection with their use of our products and technology. There is no guarantee that such parties will abide

Risks Related to Litigation

We may become involved in litigation that may materially adversely affecff

From time to time, we mayaa become involved in legal proceedings relating to matters incidental to the
ordinary course of our business, including patent, copyright, commercial, producdd t liability, employment, class
action, whistleblower and othet

proceedings. Such matters canaa be time-consuming, divert management’s attention and resources, cause us to incuruu

involved in litigation witht Cisco and OptumSoft. Because of the potential risks, expenses and uncertainties of
litigation, we may, from time to time, settle disputes, even where we have meritorious claims or defenses. Although
we have insurance which may provide coverage for some kinds of claims we may face, that insurance may not cover
some kinds of claims or types of relief and may not be adequaqq te in a particular case. Because litigation is inherently
unpredictable, we canno
you that the results of any of these actions will not have a material adverse effeff ct on

Risks Related to Cybersecurity and Data Privacy

Defects, errors or vulnerabilities in our products, the failure of our products to detect security breaches, the
misuse of our products or the risks of product liability could harm our reputation and adversely impact our
operating results.

Our products, services and internal network systems could become a target for securiuu ty attacks, including
attacks specificff ally designed to disrupt ouru business and our customers and introduce malicious software and attacks
by state sponsors. If our producdd ts, services or internal networks, system or data are or are perceived to have been
compromised, ouru reputation may be damaged and our financial results may be negatively affecff

ted.

Organizations are increasingly subjeb ct to a wide variety of attacks on their networks, systems, endpoints,
producdd ts and services, and no security solution, including our security platform, can address all possible security
threats or block all methods of penetrating a network, products and services or otherwise perpetrating a securitytt
incident. Additionally, anynn defects, errors, or vulnerabilities in our securiu ty platform or in the hardware upon which
it is deployed, including a failure to implement updates to such platforff m, could temporarily or permanently limit our
detection capabilities and expose our end-customers’ networks, leaving their networks unprnn otected against the latest

36

security threats. If customers of our security platform do suffeff
r a data security incident or data breach, even if it is
not attributable to a failure of our platform to identifyff any threat or vulnerability, customers may believe that our
platform failed to detect a threat or vulnerability, which could harm our reputation or negatively affecff
t our financial
results.

The classifications of applicatioaa

n type, virus, spyware, vulnerabia lity explx oits, data, or URL categories by
our securiu ty platform may also falsely detect, report and act on applications, content, or threats that do not actually
exist. These false positives may impair the perceived reliability of our security platform and may therefore adversely
impact market acceptance of our security platformff
. Any such false identificff ation of important files or applications
could result in damage to our reputation, negative publicity, loss of channel partners, end-customers and sales,
increased costs to remedy any problem, and costly litigation.

Breaches of our cybersecurity systems, or other security breaches or incidents with respect to our products,
services, networks, systems, or data, could degrade our ability to conduct our business operations and deliver
products and services to our customers, delay our ability to recognize revenue, compromise the integrity of
our software products and our networks, systems, and data, result in significff ant data losses and the theft of
our intellectual property, damage our reputation, expose us to liability to third parties and require us to incur
significff ant additional costs to maintain the security of our networks and data.

We increasingly depend upon our IT systems to conduct virtuat

internal operations and producd t development activities to our marketing and sales effoff

organizations may attempt to penetrate our network security, or that of our website or systems, and access or obtain
rwise sensitive or proprietary information about us or our customers or causaa e
confideff
interruptu ions of our service. These risks may increase due to the current COVID-19 pandemic. Because the
techniques used to access or sabotage networks and systems change frequently and may not be recognized until
launched against a target, we may be unabla e to anticipate these techniques. In addition, our software and
sophisticated hardware and operating system software and applications that we produce or procure from third parties
may contain defects in design or manufacture, including “bugs” and othet
e or
applications to fail or otherwise to unexpectedly interferff e with the operation of the system. We face risks of others
rized access to our products and services and introducing malicious software. We have also
gaining unauthot
turers, logistics providers, and
outsourced a number of our business functions to third-parties, including our manufacff
cloud service providers, and our business operations also depend, in part, on the success of these third parties’ own
cybersecurity measures. Similarly, we rely upon distributors, resellers and system integrators to sell our producdd ts and
our sales operations depend, in part, on the reliability of their cybersecurity measures. Additionally, we depend upon
our emplm oyees to appropriately handle confidential data and deploy our IT resources with the use of security
measures designed to prevent exposure of our network systems to security breaches and the loss of data. We and all
of the aforementioned third parties also face the risk of malicious software, phishing schemes and other social
engineering methods, fraudaa
sance, cybey rsecurity threats from state sponsors, and intentional or
negligent acts or omissions of employees and contractors. Furthermore, our acquisition of Awake Security and our
provision of its NDR platform may result in us being a more attractive target for such attacks. Accordingly, if ouru

Risks Related to Accounting, Compliance. Regulation and Tax

If we fail to maintain effeff ctive internal control over financial reporting in the future, the accuracy and timing
of our financial reporting may be adversely affecff

ted.

Assessing our processes, procedurd es and staffiff ng in order to improve our internal contrott

reporting is an ongoing process. Preparing our financial statements involves a number of complex processes, many
of which are done manually and are dependent upon individual data input or review. These processes include, but
are not limited to, calculating revenue, inventory costs and the preparation of ouruu statement of cash flows. While we
continue to automate ouruu processes and enhance our review controls to reduce the likelihood for errors, we expect

China has also imposed tariffsff on imports into China from the United States. Althoug
signed an interim trade agreement in Januaryrr 2020, the parties are continuing to negotiate a trade agreement.

t

In addition, due to concerns with the security of products and services from certain telecommunications and
video providers based in China, U.S. Congress has enacted bans on the use of certain Chinese-origin components or
systems either in items sold to the U.S. government or in the internal networks of government contractors and
subcontractors (even if those networks are not used for government-related projects). Further,
the Chinese
Government has responded to these U.S. actions by indicating its intention to develop an unreliable entity list, which
may limit the ability of companies on the list to engage in business with Chinese customers.

If tariffs,ff

trade restrictions, or trade barriers remain in place or if new tariffs,ff

trade restrictions, or trade
barriers are placed on products such as ours by U.S. or foreign governments, especially China, our costs mayaa
increase. We believe we can adjud st ouru supply chain and manufacturiu ng practices to minimize the impact of the
tariffsff
, there canaa be no assurance that we will not experience a disruption in
our business related to these or other changes in trade practices and the process of changing suppliers in order to
mitigate any such tariff costs could be complicated, time-consuming, and costly.

The U.S. tariffsff may also cause customers to delay orders as they evaluate where to take delivery of our
producdd ts in connection with their effoff
rts to mitigate their own tariffff exposure. Such delays create forecasting
difficff ulties for us and increase the risk that orders might be canceled or might never be placed. Current or future
imposed by the U.S. may also negatively impact our customers' sales, thereby causing an indirect negative
tariffsff
impact on our own sales. Even in the absence of further tariffs,ff
the related uncertainty and the market's fear of an
escalating trade war might causaa e our distributors and customers to place fewer orders for our products, which could
have a material adverse effeff ct on ouru business, liquidity, financial condition, and/or results of operations.

Given the relatively fluid regulatory environment in China and the United States and uncertainty how the

regulatory changes in the future could directly and adversely impact our financial results and results of operations.

Changes in our income taxes or our effeff ctive tax rate, enactment of new tax laws or changes in the application
of existing tax laws of various jurisdictions or adverse outcomes resulting from examination of our income tax
returns could adversely affeff ct our results.

Our income taxes are subjeb ct to volatility and could be adversely affecff

ted by several factors, many of which
are outside of our control, including earnaa ings that are lower than anticipated in countries that have lower tax rates
and higher than anticipated in countries that have higher tax rates; our ability to generate and use tax attributes;
changes in the valuation of ouru deferred tax assets and liabilities; expiration of or lapses in the federal research and

Several jurisdictions have passed new laws and regulations relating to privacy, data protection, and other
r jurisdictions are considering imposing additional restrictions. These laws continue to develop and

may be inconsistent from jurisdiction to jurisdiction. For examplm e, the California Consumer Privacy Act (“CCPA”PP )
became operative on January 1, 2020. The CCPA requires covered companies to, among other things, provide new
disclosures to California consumers, and affor

information. Certain aspects of the CCPA and its interprr etation remain uncertain and are likely to remain uncertain
for an extended period. Further, a new privacy law, the California Privacy Rights Act (“CPRA”RR ), was approved by

From time to time, we may receive inquiries from governmental agencies or we may make voluntary
disclosures regarding ouru compliance with applicable governmental regulations or requirements relating to various
matters, including import/export controls, federal securities laws and tax laws and regulations which could lead to
formal investigations. Actual or alleged noncompliam nce with applicable laws, regulations or other governmental

Risks Related to Ownership of Our Common Stock

The trading price of our common stock has been and may continue to be volatile, and the value of your
investment could decline.

The trading price of our common stock has historically been and is likely to continue to be volatile and
could be subject to wide fluctuations in response to various factors, some of which are beyond our contrott

In addition, technology stocks have historically expex rienced high levels of volatility and, if the market for
technology stocks or the stock market in general experiences a loss of investor confidff ence, the market price of our
common stock could decline for reasons unrelated to our business, financial condition, results of operations and
r
prospects. The market price of our common stock might also decline in reaction to events that affeff ct othet
companies in our industry even if these events do not directly affecff
t us. In the past, following periods of volatility in
the market price of a company’s securities, securities class action litigation has ofteff n been brought against that
company. If the market price of our common stock is volatile, we may become the target of securities litigation.
Securities litigation could result in substantial costs and divert our manaaa gement’s attention and resources from our
business and prospects. This could have a material adverse effeff ct on our business, financial condition, results of
operations and prospects.

We have adopted a stock repurchase program to repurchase shares of our common stock, however,rr any future
decisions to reduce or discontinue repurchasing our common stock pursuant to our stock repurchase program
could cause the market price for our common stock to decline.

Although our board of directors has authorized a share repurchase program, any determination to execute
our stock repurchase program will be subject to, among other
things, our financial position and results of operations,
t
available cash and cash flow, capia tal requirements, and other factors, as well as our board of director’s continuing
determination that the repurchase program is in the best interests of our shareholders and is in compliance with all
laws and agreements applicable to the repurchase program. Our stock repurchase program does not obligate us to
acquire any common stock. If we fail to meet any expectations related to stock repurchases, the market price of our
common stock could decline, and could have a material adverse impact on investor confidence. Additionally, price
volatility of our common stock over a given period may cause the average price at which we repurchase our
common stock to exceed the stock’s market price at a given point in time.

42

We may furthet

r increase or decrease the amount of repurchases of ouru common stock in the future. Any
reduction or discontinuance by us of repurchases of our common stock pursuant to our current share repurchase
authorization program could cause the market price of our common stock to decline. Moreover, in the event
repurchases of our common stock are reduced or discontinued, our failure or inability to resume repurchasing
common stock at historical levels could result in a lower market valuation of our common stock.

Sales of substantial amounts of our common stock in the public markets, or the perception that such sales
might occur,rr could reduce the market price that our common stock might otherwise attain and may dilute
your voting power and your ownership interest in us.

Sales of a substantial number of shares of our common stock in the public market, or the perception that

In addition, as a Delaware corporation, we are subjeb ct to Section 203 of the Delaware General Corporation

General Risks

If we are unable to hire, retain, train and motivate qualifieff d personnel and senior management, our business,
financial condition, results of operations and prospects could suffer.rr

t

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel,
are engineering and sales personnel. In addition, our success in expanding into adjad cent markets
particularly softwff
rt and financial resources into hiring
including the enterprise market requires a significant investment of time, effoff
and training our sales force to address these markets. If we do not effecff
tively train our direct sales force, we may be
unable to add new end customers, increase sales to our existing end customers, and successfully expand into new
markets. Competition for highly skilled personnel is ofteff n intense, especially in the San Francisco Bay Area where
we have a substantial presence and need for highly skilled personnel. Many of the companies with which we
compete for experienced personnel have greater resources than we haveaa
to provide more attractive compensation
amenities. Research and development personnel are aggressively recruited by startup and growthtt
packages and other
c regions in which we conduct
companies, which are especially active in many of the technical areas and geographi
producdd t development. In addition, in making emplm oyment decisions, particularly in the high-technology industry, job
candidates ofteff n consider the value of the stock-based compensation they are to receive in connection with their
employment. Declines in the market price of ouruu stock could adversely affecff
t our ability to attract, motivate or retain
key employees. In addition, our future perforff mance also depends on the continuenn d services and continuing
contributions of our senior management to execute our business plan and to identifyff and pursue new opportunitie
s
and product innovations. Our employment arrangements with our emplm oyees do not generally require that they
continue to work for us for any specifieff d period, and therefore, they could terminate their employment with us at any
time. If we are unable to attract or retain qualifieff d personnel, or if there are delays in hiring required personnel, ouruu
business, financial condition, results of operations and prospects may be seriously harmed.

Our common stock is listed on the NYSE under the symbol “ANET”. As of February 12, 2021, there
were 61 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.

Recent Sales of Unregistered Equity Securities

There were no sales of unregistered securities during fiscal year 2020.

Issuer Repurchases of Equity Securities

Under ouru equity incentive plans, certain participants may exercise options prior to vesting, subject to a
right of repurchase by us. During the fourth quarter of 2020, there were no repurcuu hases of unvested shares of
our common stock made pursu uant to our equiqq ty incentive plans as a result of us exercising our rights nor
pursuant to any publicly - announced plan or program.aa

Stock Repurchase Program

In April 2019, our board of directors authorized a $1.0 billion stock repurchase program (the
“Repurchase Program”). This authorization allows us to repurchase shares of ouru common stock over three
years and will be funded from operating cash flows. Repurchases may be made at management’s discretion
from time to time on the open market, through privately negotiated transactions, transactions structured through
investmet
nt banking institutions, block purcuu hases, trading plans under Rule 10b5-1 of the Exchange Act, or a
combination of the foregoing. The Repurchase Program, which expix res in April 2022, does not obligate us to
acquire any of our common stock, and may be suspended or discontinued by us at any time without prior notice.
We did not make any repurchases for the three months ended December 31, 2020, as disclosed in the table
below (in thousands, except per share amounts). For ouruu repurchase activities made during the rest of the year
ended December 31, 2020, please refer to Note 8. Stockholders' Equity and Stock-Based Compensation of the

Overview

Arista Networks pioneered software-driven, cognitive cloud networking for large-scale data center and
campus workspace environments. Our industry-leading cloud networking platforff m is highly scalable and
programmable, and purpose built to address the functional and performance requirements for cloud networks,
including workflow automation, network visibility and analytics, and has furtuu her allowed us to integrate rapidly
with a wide range of third-partytt

We generate revenue primarily from sales of our switching and routing platforms, which incorpor

ate
our EOS software, and related network applications. We also generate revenue from post contract support, or
PCS, which end customers typically purchase in conjunction witht our products, and renewals of PCS. We sell
our producdd ts through botht our direct sales force and our channel partnett
rs. Ouru end customers span a range of
industritt es and include large internet companies, service providers, financial services organizations, government
rs.
agencies, media and entertainment companies and othet

rr

Historically, large purchases by a relatively limited number of end customers have accounted for a
significant portion of ouru revenue. We have experienced unpredictability in the timing of orders from these large
end customers primarily due to changes in demand patterns specificff
to these customers, the time it takes these
end customers to evaluate, test, qualify and accept our products, and the overall complexity of these large
orders. We expect continued variability in ouru customer concentration and timing of sales on a quarterly and
annual basis. For example, sales to our end customers Microsoftff and Facebook in fiscal 2019 collectively
represented 40% of our total revenue, whereas sales to our end customer Microsoft in fiscal 2020 amounted to
21.5% of our revenues, with our end customer Facebook representing less than 10% of our revenues in the
period. These changes contributed to a year-over-year decline in our revenue for fiscal 2020. However, this
decline in revenue from these large end customers was in part offset
ise and other
cloud and service provider customers.
In addition, we typically provide pricing discounts to large end
customers, which may result in lower margins for the period in which such sales occur.

in the future as the market
producdd ts and services and industryt
for cloud networking expandaa
s and existing competitors and new market entrants introduce new producdd ts or
enhance existing products. Our future success is dependent upon our ability to continue to evolve and adapt to
our rapidly changing environment. We must also continue to develop market leading products and featureu s that
address the needs of our existing and new customers, and increase sales in the enterprise data center switching,
and campus workspace markets. We intend to continue expanding our sales force and marketing activities in
key geographies, as well as our relationships with channel, technology and system-level partnet
rs in order to
reach new end customers more effeff ctively, increase sales to existing customers, and provide services and
support. In addition, we intend to continue to invest in our research and development organization to enhance
the funcu tionality of our existing cloud networking platform, introduce new products and featurtt es, and build
upon our technology leadership. We believe one of our greatest strent
gths lies in our ability to rapidly develop
new features and applications.

Our development model is focused on the development of new products based on our EOS softwa

re
and enhancements to EOS. We engineer our producdd ts to be agnostic with respect to the underlying merchant

Recent Developments

The global coronavirus (“COVID-19”) pandemic and related shelter in place, travel and social
rt to contain or slow its spread have
distancing restritt ctions imposed by governments around the world in an effoff
negatively impacted the global economy, disrupted business, sales activities, supply chains and workforce
participation, including our own, and created significant volatility and disruption of financial markets, and we
expect that the global health crisis caused by COVID-19 will continue to negatively impact business activity for
the foreseeabla e future.

We have taken numerous steps, and will continue to take further actions, in our approach to address
COVID-19. We have prioritized the protection of our emplm oyees during this pandemic and, as a result, have
closed our offiff ces across the globe (including our corporate headquarters), limiting access to only those
employees providing essential activities, instructed employees to work from home, and implemented travel
restritt ctions. We continue to work closely with our contract manufactureu rs and supply chain partners who haveaa
experienced delays in component sourcing, workforff ce disruptions and governmental restrictions on the
producdd tion and export of their products. Although we haveaa worked diligently to drive improvements in these
and incremental purchase commitments, these delays have
areas, including funding additional working capital
negatively impacted our ability to suppu
ly products to our customers on a timely basis. We expect to continue to
invest in working capiaa tal as supply availability improves in order to address the risk of future COVID-19 related
supply chain disruptions, but we cannot be certain that such disruptuu ions will not occur. When the COVID-19
in customer demand, but sales activity subsequently
pandemic began, we initially experienced some volatilitytt
stabilized and we experienced incremental improvements in overall demand as the year progressed. However,
the supply chain disruptions outlined above and the earlaa ier volatility in customer demand contributed in part to a
year-over-year decline in total revenue for the year ended December 31, 2020.

aa

The extent of the impact of COVID-19 on our operational and financial perforff mance, including our
ability to execute ouruu business strategies and initiatives in the expected time frame, will depend on future
n of governmental
developments, including the duration and spread of the pandemic, the breadth and durauu tioaa

51

containment measures such as shelter in place,
travel and social distancing restritt ctions as well as the
reauthorization of or increase in such measures in the event of spikes in COVID-19 infection rates, the success
of the COVID-19 vaccination deployment, and the impact on our customers, partners, contract manufacturtt ers
and supply chain, all of which are uncertain and cannot be predicted. However, any continued or renewed
disruption in manufactu
ring and supply resulting from the COVID-19 pandemic or related containment
measures could negatively impact ouru business. We also believe that any extended or renewed COVID-19
related economic disruption could have a negative impact on demand from our customers in future periods.
Accordingly, current results and financial condition discussed herein mayaa not be indicative of future operating
results and trends.

ff

In response to potential future COVID-19 related disruptions to our business, we have continued to
carefully review our investment and spending plans, cautiously increasing incremental spending in the second
half of fiscal 2020 as overall customer demand stabilized. Although management is actively monitoring the
impact of COVID-19 on the Company’s financial condition, liquidity, operations, suppliers, industryt
,y and
workforce, the full impact of the pandemic continues to evolve as of the date of this report. As such, the
Company is unable to estimate the effecff
ts of COVID-19 on its future results of operations, financial condition,
or liquidity.

Acquisitions

purchased in conjunction with our products, and subsequent renewals of those contracts. We expect our revenue
may vary from period to period based on, among other things, the timing, size, and complexity of orders,
especially with respect to our large end customers.

Product revenue decreased $190.3 million, or 9.4%, in the year ended December 31, 2020 compared to
2019. The decrease was primarily due to the recognition of $125.1 million of deferred product revenue in the
year ended December 31, 2019 related to customer acceptance of products shipped in prior periods. In addition,
we experienced reduced sales to our larger customers during fiscal 2020, combined with the impact of some
COVID-19 related supply constraints. Service revenue increased $97.1 million, or 24.9% in the year ended
December 31, 2020 compam red to 2019 as a result of continued growth in initial and renewal support contracts as
our customer installed base continued to expax nd. International revenues remained relatively constant at 23.5%
of total revenues in the year ended December 31, 2020, compared to 23.9% in 2019, withtt a slight decrease in

Cost of revenue decreased $30.7 million or 3.5% for the year ended December 31, 2020 compared to
2019. The decrease in cost of revenue was primarily due to a corresponding decrease in producdd t revenues, and
was partially offsff et by incremental COVID-19 related supply chain costs and increased product transition costs.

Gross margin, or gross profitff as a percentage of revenue, has been and will continue to be affeff cted by a
variety of factors, including pricing pressure on our products and services due to competition, the mix of sales
facturiu ng-related costs, including costs
to large end customers who generally receive lower pricing, manuaa
associated with supply chain sourcing activities, merchant silicon costs,
the mix of producdd ts sold, and

above.

Gross margin slightly decreased from 64.1% for the year ended December 31, 2019 to 63.9% in 2020.
Gross margin was negatively impacted by incremental COVID-19 related supply chain costs and some
increased producdd t transition costs, combined witht
the impact of fixed overhead costs on a lower revenue base.
These negative impacts were partially offsff et by a reduction in sales to our larger end customers who generally
receive larger discounts, and improved service margins as we scale our services organization.

are focused on new product development and maintaining and developing additional functionality for our
existing products, including new releases and upgrades to our EOS softwatt

research and development expenses to increase in absolute dollars as we continue to invest in software
development in order to expand the capabilities of our cloud networking platforff m, introducdd e new products and
featurtt es, and build upon our technology leadership.

Research and development expenses increased $23.8 million, or 5.2%,

the year ended
December 31, 2020 compared to 2019. The increase was primarily due to a $26.8 million increase in stock-

services.

General and administrative expenses increased $4.3 million, or 7.0%, for the year ended December 31,

We operate in a number of tax jurisdictions and are subjeu

which we conduct business. Earnings from our non-U.S. activities are subject to local country income tax and
may also be subject to U.S. income tax. Generally, our U.S. tax obligations are reduced by a credit for foreign
income taxes paid on these foreign earnings, which avoids double taxation. Our tax expense to date consists of
federal, state and foreign current and deferred income taxes.

Product revenue increased $180.1 million, or 9.8%, in the year ended December 31, 2019 compared to
2018. The increase was primarily driven by increased demandaa
from botht new and existing customers, and the
recognition of product deferred revenue related to sales in the prior year for which revenue was recognized in
2019. Service revenue increased $79.3 million, or 25.6% in the year ended December 31, 2019 compared to
2018 as a result of continued growth in initial and renewal support contrat cts as our customer installed base has
continued to expax nd. International revenues represented 23.9% of total revenues in the year ended Decembem r
31, 2019, compared to 27.9% in 2018, which was primarily due to a move toward U.S. deployments by certain
of ouru large end customers during 2019. We continue to experience pricing pressure on our products and
services due to competition, but demand for our products and growth in our installed base has more than offset
this pricing pressure duriuu ng the year. However, we have experienced reduced and volatile demand from certain
of our large end customers during 2019.

and development

Research and development expex nses increased $20.3 million, or 4.6%, for the year ended December
31, 2019 compared to 2018. The increase was primarily due to a $17.2 million increase in personnel costs
driven primarily by headcount growth, and a $7.8 million increase in development-related facilities costs due to
facilities expansion and headcount growth, partially offsff et by a $5.9 million decrease in new product

Sales and marketing

Sales and marketing expenses increased $26.8 million, or 14.3%, for the year ended December 31,

driven by increased headcountuu

istrative

General and administrative expenses decreased $3.5 million, or 5.4%, for the year ended December 31,

the settlement of ouruu litigation with Cisco in August 2018.

Legal settlement

During the three months ended June 30, 2018, we recorded $405.0 million in legal settlement expenses
in connection with the Term Sheet that was entered into on August 6, 2018 between the Company and Cisco,
which included a $400.0 million paymaa
the settlement. Pursuant
to the Term Sheet, the Company and Cisco obtained dismissals of all then ongoing district court and USITC

which superseded the Term Sheet but did not substantially alter the terms.

Liquidity and Capital Resources

Our principal sources of liquidity are cash, cash equivalents, marketable securities, and cash generated
from operations. As of December 31, 2020, our total balance of cash, cash equivalents and marketable securities

continue to invest for long-term growth. We believe that our existing balances of cash, cash equivalents and
marketable securities, together with cash generated from operations will be suffiff cient to meet our working
capia tal requirements and our growth strategies for at least the next 12 months. Our future capia tal requirements
will depend on many factors, including our growth rate, the timing and extent of our spending to support

Critical Accounting Policies and Estimates

We have prepared our consolidated financial statements in accordance witht

accounting principles
generally accepted in the United States ("GAAP" or "U.S. GAAP") and include our accounts and the accounts
of our wholly owned subsidiaries. The preparation of these consolidated financial statements requires our
management to make estimates, assumptions and judgments that affect
the reported amounts of assets and
liabilities at the date of the financial statements, disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenue and expex nses during the applicable periods. We base
our estimates, assumptions and judgments on historical experience and on various other factors that we believe
ent assumptions and judgments would change the estimates
to be reasonable under the circumstances. Differ

those reported. We evaluate our estimates, assumptions and judgments on an ongoing basis. Actual results may

SSP for products and PCS sold together in a contract to determine whether there is a discount to be allocated
based on the relative SSP of the various products and PCS.

If we do not have an observabla e SSP, such as when we do not sell a producd t or service separately, then
SSP is estimated using judgment and considering all reasonably available information such as market conditions
and information about the size and/or purchase volume of the customer. We generally use a range of amounts to
estimate SSP for individual producd ts and services based on multiple factors including, but not limited to, the
sales channel (reseller, distributor or end customer), the geographies in which our producd ts and services are
sold, and the size of the end customer.

We limit the amount of revenuenn

recognition for contrat cts containing forms of variable consideration,
such as future performa
nce obligations, customer-specific returns, and acceptance or refund obligations. We
include some or all of an estimate of the related at risk consideration in the transaction price only to the extent
that it is probable that a significant reversal in the amount of cumulative revenue recorded under each contract
will not occur when the uncertainties surrounding the variable consideration are resolved.

Most of our contracts with customers have payment terms of 30 days, with some large high volume
customers having terms of up to 60 days. We have determined that our contracts generally do not include a
significant financing component because the Companynn and the customer have specificff
business reasons other
than financing for entering into such contract
ts. Specificff ally, both we and our customers seek to ensure the
customer has a simplifieff d way of purchasing our products and services.

We may occasionally accept returns to address customer satisfaction issues even though there is

Inventories primarily consist of finished goods and strategic components, primarily integrated circuits.
Inventories are stated at the lower of cost (computed using the first-in, first-out method) and net realizable

record a provision when inventory is determined to be in excess of anticipated demand, or obsolete, to adjud st

Our contract manufacturers procure components and assemble producdd ts on our behalf based on our

We account for income taxes under the liability approach for deferred income taxes, which requires
recognition of deferred income tax assets and liabilities for the expected future tax consequences of events that
have been recognized in our consolidated financial statements, but have not been reflected in our taxable
income. Estimates and judgments occur in the calculation of certain tax liabilities and in the determination of
the recoverability of certain deferred income tax assets, which arise from temporary differeff

red income tax assets and liabilities are measured using the currently enacted tax rates that

that we are more likely than not to realize.

final tax outcome of these matters is differff ent than the amounts recorded, such differenc

We regularly review our tax positions and benefits to be realized. We recognize tax liabilities based
upon our estimate of whether, and to the extent to which, additional taxes will be due when such estimates are
more likely than not to be sustained. An uncertain income tax position will not be recognized if it has less than a
50% likelihood of being sustained. We recognize interest and penalties related to income tax matters as income
tax expense.

The U.S. tax rules require U.S. tax on foreign earnaa ings, known as global intangible low taxed income
(“GILTI”). Under U.S. GAAP,PP we are allowed to make an accounting policy choice of either (1) treating taxes

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk in the ordinary course of our business. Market risk represents the risk of
loss that may impact our financial position due to adverse changes in financial market prices and rates. Our

market risk expos

global financial markets, which may increase ouru foreign currency exchange risk and interest rate risk. For
further discussion of the potential impacts of the COVID-19 pandemic on our business, operating results, and
financial condition, see Risk Factors included in Part I, Item 1A of this Form 10-K.

Foreign Currency Exchangen Risk

Our results of operations and cash flows are subjeb ct to fluctuations due to changes in foreign currency
exchange rates. Substantially all of our revenue is denominateaa d in U.S. dollars, and therefore, our revenue is not

U.S. dollar could make our products and services more expensive in foreign countrit es and thereforff e reduce
demand. A weaker U.S. dollar could have the opposite effeff ct. Such economic exposureu
to currency fluctuations
is difficff ult to measure or predict because our sales are also influenced by many othett

r factors.

Our expenses are generally denominated in the currencies in which our operations are located, which is
primarily in the U.S. and to a lesser extent in Europe and Asia. Our results of operations and cash flows are,
thereforff e, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely
ted in the future due to changes in foreign exchange rateaa s. A hypothetical 10% change in foreign currency

exchange rates on ouru monetary assets and liabilities would not be material to our financial condition or results
of operations. To date, foreign currency transaction gains and losses and exchange rate fluctuatt

transactions to date and do not enter into any hedging contracts for trading or speculative purpor

income sensitivity, which is affeff cted by changes in the general level of the interest rates in the U.S. A decline in
interest rates would reduce our interest income on our cash, cash equivalents and marketable securities. For the
of a hypothetical 100 basis point increase or
years ended December 31, 2020, 2019 and 2018, the effect

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2020,
based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring

Basis for Opinion

These financial statements are the responsibility of the Company’s manaaa gement. Our responsibility is to express
an opinion on the Company’s financial statements based on our audits. We are a public accounting firm
registered with the 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.

aa

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financaa
ial statements are free of material
misstatement, whethet
r due to error or fraud. Ouru audits included perforff ming procedures to assess the risks of
material misstatement of the financial statements, whether due to error or fraud, and perforff ming procedures that
respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts
and disclosures in the financial statements. Our audits also included evaluating the accounting principles used
and significant estimates made by management, as well as evaluating the overall presentation of the financial
statements. We believe that ouru audits provide a reasonabla e basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial
statements that was communicated or required to be communm icated to the audit committee and that: (1) relates
to accounts or disclosures that are material to the financaa

Organization and Summary of Significant Accounting Policies

Organizatiott n

Arista Networks, Inc. (together with our subsidiaries, “we,” “our,” "Arista," "Company" or “us”) is a
supplier of cloud networking solutions that use software innovations to address the needs of large-scale internet
companies, cloud service providers and next-generation enterprises. Our cloud networking solutions consist of
our EOS, a set of network applications and our Gigabit Ethernet switching and routing platforff ms. We are
incorporated in the state of Delaware. Our corporate headquarters are located in Santa Clara, California, and we
have wholly-owned subsidiaries throughout the world, including Northtt America, Europe, Asia and Australia.

Basisii of Presentation and Prinr ciplii esll

of Consolidatdd iott n

The accompanyi

ng consolidated financial statements include the accounts of Arista Networks, Inc. and
its wholly-owned subsidiaries and are prepared in accordance with accounting principles generally accepted in
the United States ("GAAP"). All significant intercompanyaa

accounts and transactions have been eliminated.

Use of Estimates

The preparation of the accompanying consolidated financial statements in conforff mity with GAAP
the amounts reported and disclosed in the

consolidated financaa
not limited to, revenuenn
recognition and deferred revenuenn ; allowance for doubtful accountu s, sales rebates and
return reserves; valuation of goodwill and acquisition-related intangible assets, accounting for income taxes,
including the recognition of deferred tax assets and liabilities related to an intra-entity transaction to sell ouru
non-Americas economic and beneficial intellectuatt
valuation allowance on deferred tax assets and
l property,tt
reserves for uncertain tax positions; estimate of useful lives of long-lived assets including intangible assets;
valuation of inventory and contract manufacturer/supplier liabilities; and the recognition and measurement of
r
contingent liabilities. We evaluate our estimates and assumptions based on historical experience and othet
factors and adjud st these estimates and assumptions when facts and circumstances dictate. Actual results could
differff materially from these estimates.

We work closely with third-partytt

contract manufacturers to manufacture our products. As of
December 31, 2020, we had two primary contract manufacturing partners, who provided substantially all of ouru
turiu ng partners deliver our products to our third-partytt
electronic manufacturtt
direct fulfillme
rs then perform labeling, final configff uration, quality
assurance testing and shipment to our customers. Ouruu products rely on key components, including certain
integrated circuit components and power supplies, some of which our contract manuf
turiuu ng partaa ners purchase
iers, including certain sole-source providers. We generally do not
uu
on our behalf from a limited number of suppl
have guaranteed supply contracts with our component suppliers, and ouruu manufacff
rs could delayaa
shipments or cease manufacturing such producdd ts or selling them to us at any time. If we are unable to obtain a
sufficff
ient quantity of these components on commercially reasonable terms or in a timely manner, or if we are
unable to obtain alternative sources for these components, sales of our producdd ts could be delayed or halted
nce failures of our products or
entirely, or we may be required to redesign our products. Quality or perforff marr
changes in our contractors’ or vendors’ financial or business condition could disruptuu
our ability to supply qualitytt
producdd ts to our customers. Any of these events could result in lost sales and damage to our end-customer
relationships, which would adversely impact our business, financial condition and results of operations.

turing partnet

acff

aa

Financial instrut ments that potentially subject us to concentrations of credit risk consist primarily of
cash, cash equiqq valents, markaa etable securities, restricted cash, and accounts receivable. Our cash equivalents,
restritt cted cash and marketable securities are invested in high quality financial instruments with banks and
financial institutions. Such deposits may be in excess of insured limits provided on such deposits.

Our accounts receivabla e are unsecured and represent amounts due to us based on contractual
obligations of our customers. We mitigate credit risk witht
respect to accounts receivable by perforff ming ongoing
credit evaluations of our customers to assess the probability of collection based on a number of factors,
including past transaction experience with the customer, evaluation of their credit history, the credit limits
extended, review of the invoicing terms of the arrangement and current economic conditions that may affecff
t a
customer’s ability to pay. In situations where a customer mayaa be thinly capiaa talized and we have limited payment
history with it, we will either establish a small credit limit or require it to prepay its purchases. We generally do
ort accounts receivable. We have recorded an allowance
not require ouruu customers to provide collateral to suppu
for doubtfulff
accounts for accounts receivables that we have determined to be uncollectible. We mitigate credit
risk with respect to accounts receivables by performing ongoing credit evaluations of the borrower to assess the
probabia lity of collecting all amounts due to us under the existing contractual terms.

We market and sell our products through both our direct sales force and our channel partners, including
distributors, value-added resellers, system integrators and original equipment manufacturer (“OEM”) partners,
and in conjun nction with various technology partaa ners. Significant customers are those that represent more than
10% of our total net revenue during the period or net accounts receivable balance at each respective balance
sheet date. As of December 31, 2020, we had two customers who represented 31% and 15% of total accounts
receivable, respectively. As of December 31, 2019, we had one customer who represented 39% of total accounts
receivable. For the years ended December 31, 2020 and 2018, there was one customer who represented 22%
and 27% of our total revenue, respectively. For the year ended December 31, 2019, there were two customers
who represented 23% and 17% of our total revenue, respectively.

Cash and Cash Equivalentstt

We consider all highly liquid investments with original or remaining maturities of three months or less
at the time of purchase to be cash equivalents. Cash and cash equivalents consist of cash on deposit witht
various financial institutions and highly liquiqq d investments in money market funds. Interest is accruerr d as
earned. As of December 31, 2020 and 2019, we had restricted cash of $4.2 million, respectively, and that
primarily included $4.0 million pledged as collateral representing a security deposit required for a facility lease.
Our restricted cash is classifieff d as other assets in the accompam nying consolidated balance sheets.

77

Marketable Securities

We classifyff all highly liquid investmet

nts in debt and equity securities with maturities of greater than
three months at the date of purchase as marketable securities. We have classified and accounted for ouru
nts at
marketable securities as available-for-sale. We determine the appropriate classificff ation of these investmet
the time of purchase and reevaluate such designation at each balance sheet date. We may or may not hold
securities with stated maturities greater than 12 monthstt
r consideration of ouru risk versus
reward objeb ctives, as well as our liquidity requirements, we may sell these securities prior to their stated
maturities. As we view these securities as available to support current operations, we classify securities with
maturities beyond 12 months as current assets under the caption marketabla e securities in the accompanying
consolidated balance sheets. We carryrr
these securities at fair value, and report the unrealized gains and losses,
net of taxes, as a component of stockholders’ equity. We determine the cost of the debt investment sold based on
r income, net in the
an average cost basis at the individual securiu ty level, and record the interest income in othett
accompanying consolidated statements of operations. We determine any realized gains or losses on the sale of
marketable securities using the specificff
r income,
net in the accompanyinn ng consolidated statements of operations.

identificff ation method, and record such gains and losses in othet

until maturity. Afteff

For our debt securities in an unrealized loss position, we determine whether a credit loss exists by
considering information about the collectability of the instrument and curreu
nt market conditions. We recognize
an allowance for credit losses, up to the amount of the unrealized loss when appropriate, and write down the
amortized cost basis of the investment if it is more likely than not we will be required to sell or we intend to sell
the investmet

nt before recovery of its amortized cost basis.

Accountstt Receivable

Accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts,
accounts based upon the
sales rebates and returtt ns reserves. We estimate our allowance for doubtfulff
collectability of the receivables in light of historical trends, reasonable and suppu
ortable information of our
customers' economic conditions that may affeff ct our customers’ ability to pay and prevailing economic
conditions. This evaluation is done in order to identify issues that may impact the collectability of receivables
nt to bad debt
and related estimated required allowance. Revisions to the allowance are recorded as an adjud stmet
expense. After appropriate collection effoff
accounts receivable deemed to be
uncollectible are charged against the allowance in the period they are deemed uncollectible. Recoveries of
accounts receivable previously written-offff are recorded as credits to bad debt expense. We primarily estimate
our sales rebates and returnu s reserves based on historical rates applied against curreu
nt period billings. Specificff
customer returtt ns, rebates and allowances are considered when determining our estimates. Revisions to sales
rebate and return reserves are recorded as adjud stments to revenue.

Fair Value Measurementstt

Fair value is defined as the exchange price that would be received for an asset or an exit price that
would be paid to transferff
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. We apply fair value accounting for all
financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a
recurring basis. These assets and liabilities include cash and cash equivalents, marketabla e securities, accounts
receivable, accounts payable, and accrued liabilities. Cash equivalents, accounts receivable, accounts payabla e
and accrued liabilities are stated at carrying values in our consolidated financial statements, which approximate
their fair value due to the short-rr term nature of these instruments.

Assets and liabilities recorded at fair value on a recurring basis in the accompanyinn ng consolidated
balance sheets are categorized based upon the level of judgment associated with the inputs used to measure
their fair value. We use a fair value hierarchy to measureuu
fair value, maximizing the use of observable inputs
and minimizing the use of unobservablea

inputs. The three-tiers of the fair value hierarchy are as follows:

Property and equipment are stated at cost, less accumulated depreciation. Depreciation is calculated

Leases

We lease officff

expiration dates through 2028. We determine if an arrangement contains a lease at inception. Operating leases
are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease
liabilities, non-current in our consolidated balance sheets. We do not have any financaa

periods presented.

ROU assets and lease liabilities are recognized at the commencement date based on the present value
ents over the lease term. The interest rate implicit in our operating leases is not readily
of remaining lease paymaa

collateralized basis with similar terms, payments, and economic environments. Operating lease right-of-use
assets also include any prepaid lease payments and lease incentives.

Our operating lease agreements may contain rent concession, rent escalation, and option to renew
provisions. Lease expense is recognized on a straight-line basis over the lease term commencing on the date we
have the right to use the leased property. Our lease terms may include options to extend or terminate the lease
when it is reasonabla y certain that the option will be exercised. In addition, certain of our operating lease
agreements contain tenant improvement allowances from landlords. These allowances are accounted for as
lease incentives, and decrease our right-of-uff

Our lease agreements may contain lease and non-lease components, which are combined and
accounted for as a single lease component. We also elect to apply the short-term lease measurement and
recognition exemptm ion in which ROU assets and lease liabilities are not recognized for leases with terms of 12
months or less.

ss Combinations

We use the acquisqq

Accounting Standards Codificff ation ("ASC") 805 - Business Combinations. We allocate the total fair value of
purchase consideration to the tangible and intangible assets acquired and liabilities assumed based on their
estimated fair values. The excess of the consideration transferred over the fair values of the assets acquired and
liabilities assumed is recorded as goodwill. The results of operations of the acquired businesses are included in
our consolidated financial statements from the date of acquisition. Acquisition-related transaction and
restrutt cturing costs are expensed as incurred.

During the measurement period, which is not to exceed one year from the acquiqq sition date, we may
record adjud stments to the acquired assets and liabilities assumed, with a corresponding offsff et to goodwill or the
preliminary purchase price, to refleff ct new information obtained about facts and circumstances that existed as of
the acquisition date. Upon the conclusion of the measurement period, any subsequent adjustme

Goodwidd llii and Acquired Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of net assets acquired in a
business combination. The Company has one reporting unit and tests goodwill for impairment at least annually
in the fourth quarter or more frequently if indicators of potential impairment exist. We first perforff m a
qualitative assessment to determine whether it is more likely than not that the fair value of ouruu reporting unit is
less than its carrying amount. If the reporting unit does not pass the qualitative assessment, a quantitative test is

record a provision for contingent losses when it is both probable that an asset has been impaired or a liabilitytt
has been incurred and the amount of the loss can be reasonably estimated. We will record a charge equal to the
minimum estimated liability for litigation costs or a loss contingency only when both of the following
conditions are met: (i) information available prior to issuance of our consolidated financial statements indicates
that it is probable that a liability had been incurred at the date of the financial statements, and (ii) the range of
loss can be reasonabla y estimated. We regularly evaluate current information available to us to determine
whether such accruarr

Revenue Recognition

o

We generate revenue from sales of our products, which incorporate our EOS software and accessories
such as cabla es and optics, to direct customers and channel partners together with post-contractt
t customer support
(“PCS”). We typically sell products and PCS in a single contract. We recognize revenue upon transfer of control
of promised producdd ts or services to customers in an amount that reflects the consideration we expect to be
entitled to receive in exchange for those products or services. We apply the following five-step revenue
recognition model:

•

•

•

•

•

Identification of the contract, or contrat cts, with a customer

Identification of the perforff mancaa

e obligations in the contract

Determination of the transaction price

Allocation of the transaction price to the performance obligations in the contratt ct

Recognition of revenue when (or as) we satisfy the perforff mancaa

e obligation

81

Post-Contract Customer Suppu

ort

PCS, which includes technical support, hardware repair and replacement parts beyond standard
red under
warranty, bug fixes, patches and unspecifieff d upgrades on a when-and-if-aff vailable basis, is offeff
renewable, fee-based contracts. We initially defer PCS revenue and recognize it ratably over the life of the PCS
contract as there is no discernible pattern of delivery related to these promises. We do not provide unspecifieff d
upgrades on a set schedule and address customer requests for technical support if and when they arise, with the
related expenses recognized as incurred. PCS contracts generally have a term of one to three years. We include
billed but unearned PCS revenue in deferred revenue.

Contrat

ctstt with Multiple Perforff mance Obligations

Most of our contractt

nce obligations. Our hardware includes EOS software, which together deliver

ts with customers, other than renewals of PCS, contain multiple perforff mance
as distinct
obligations with a combination of products and PCS. Products and PCS generally qualifyff
perforff marr
the essential
functionality of our products. For contracts that contain multiple performance obligations, we allocate revenue
to each distinct performance obligation based on the standalone selling price (“SSP”). Judgment is required to
determine the SSP for each distinct performance obligation. We use a range of amounts to estimate SSP for
productdd
s and PCS sold together in a contract to determine whether there is a discount to be allocated based on
the relative SSP of the variaa ous producdd ts and PCS.

If we do not have an observable SSP, such as when we do not sell a producdd t or service separately, then
SSP is estimated using judgment and considering all reasonablya
available information such as market
conditions and information about the size and/or purchase volume of the customer. We generally use a range of
amounts to estimate SSP for individuadd l producdd ts and services based on multiple factors including, but not
limited to, the sales channel (reseller, distributor or end customer), the geographies in which our products and
services are sold, and the size of the end customer.

We limit the amount of revenuenn

recognition for contracts containing forms of variable consideration,
such as future perforff mance obligations, customer-specificff
returns, and acceptance or refund obligations. We
include some or all of an estimate of the related at risk consideration in the transaction price only to the extent
that it is probable that a significant reversal in the amountuu
of cumulative revenue recorded under each contract
will not occur when the uncertainties surrounding the variable consideration are resolved.

Most of our contracts with customers have payment terms of 30 days with some large high-volume
customers having terms of up to 60 days. We have determined our contracts generally do not include a
significant financing component because the Company and the customer have specificff
business reasons other
than financing for entering into such contracts. Specificff ally, both we and our customers seek to ensure the
customer has a simplifieff d way of purchasing Arista products and services.

We account for multiple contratt cts with a single partnett

r as one arrangement if the contractuatt
and/or substance of those agreements indicate that they may be so closely related that they are, in effff ecff
of a single contract.

l terms
t, parts

We may occasionally accept returns to address customer satisfaction issues even though there is
generally no contractual provision for such returns. We estimate returns for sales to customers based on
historical return rates applied against current-period shipments. Specificff
customer returns and allowances are
considered when determining our sales return reserve estimate.

Our policy applies to the accounting for individual contracts. However, we have elected a practical
expedient
to apply the guidance to a portfolio of contracts or performance obligations with similar
characteristics so long as such application would not differff materially from applying the guidance to the
individual contracts (or performa

The U.S. tax rules require U.S. tax on foreign earnings, known as global intangible low taxed income

incorporating the solutions of the acquired businesses into ouru technology platforff m, and the value of the

86

assembled workforce. The goodwill is not deductible for income taxes purpor
ses. The Company’s consolidated
financial statements include the accounts of Big Switch and Awake Security starting as of the acquisition date.
Pro forma and historical post-acquisition results of operations for these acquiqq sitions were not material to the
Company’s consolidated financial statements.

(1) As of December 31, 2019, all of our certificaff

tes of deposits were domestic deposits.

As of December 31, 2020 and 2019,

total unrealized losses of our marketable securities were
immaterial. We invest in marketable securities that have maximum maturities of up to two years and are
generally deemed to be low risk based on their credit ratings from the majoa r rating agencies. The longer the
duration of these marketable securities, the more susceptible they are to changes in market interest rates and
bond yields. We expect to realize the full value of these investments upon maturity or sale and therefore, we do
not consider any of our marketable securities to be impaired as of December 31, 2020. We did not recognize any
credit losses or non-credit-related impairments related to our available-forff
-sale marketable securities for the
year ended December 31, 2020. We determined that the gross unrealized losses on our marketable fixed-income
securities as of December 31, 2019 and 2018 were temporm aryrr
in nature and therefore, we did not recognize any
impairment of our marketable fixed-income securities for the years ended December 31, 2019 and 2018,
respectively.

As of December 31, 2020, the contractual maturities of ouruu investments did not exceed 24 months. The
fair values of available-for-sale marketable securities, by remaining contractual maturity, are as follows (in

Our investments in privately-held companies do not have readily determinable fair values. Their initial
cost is subsequently adjud sted to fair value on a non-recurring basis based on observable price changes from
orderly transactions of identical or similar securities of the same issuer or for impairment. These investments are
classifiedff
within Level III of the fair value hierarchy as we estimate the value based on valuation methods using
r significant unobservable inputs, such as
the observable transaction price at the transaction date and othet
volatility, rights, and obligations related to these securities. In addition, the valuation requires management
judgment due to the absence of market price and lack of liquidity. The following table summarizes the activity
related to ouru investments in privately-held companies held as of December 31, 2020 and 2019 (in thousands):

$4.2 million, $1.2 million and $1.2 million of unrealized gains, respectively. These unrealized gains were
recorded on investments that were re-measured to fair value as of the date observable transactions occurred. In
addition, during the year ended December 31, 2018, we recorded an impairment of $15.0 million on one of our
disposed investments. The aforementioned realized and unrealized gains and impairment were recorded within

We lease various offiff ces and data centers in North America, Europe, Asia and Australia under non-
cancelable operating lease arrangements that expire on various dates through 2028. Some of ouru leases include
options to extend the term of such leases for a period from three months to up to 10 years and/or options to early
terminate the leases. As of December 31, 2020, we did not include any such options in determining the lease
terms because we were not reasonably certain that we would exercise these options.

The operating lease costs in the table above include costs for long-term and short-term leases. Total
short-term lease costs were immaterial. Fixed lease costs include expenses recognized for base rent payments on
a straight-lined basis. Variable lease costs primarily include maintenance, utilities and operating expex nses that
are incremental to the fixed base rent payments, and are excluded from the calculation of operating lease
liabilities and ROU assets. For the years ended December 31, 2020 and 2019, cash paid for amounts associated
with our operating lease liabilities were approximately $20.2 million and $18.6 million, respectively, which
were classified as operating activities in the accompanying consolidated statements of cash flows.

of product and service perforff marr
tee provisions and our guarantee
We have not recorded a liability related to these indemnificff ation and guaranaa
and indemnificff ation arrangements have not had any material impact on our consolidated financial statements to
date.

Legal Proceedings

In the ordinary course of business, we are a partytt

to claims and legal proceedings including matters

relating to commercial, employee relations, business practices and intellectuatt

l property.tt

We record a provision for contingent losses when it is both probable that a liability has been incurred
and the amount of the loss canaa be reasonably estimated. Based on currently availabla e information, management
does not believe that any liabilities relating to other unresolved matters are probable or that the amountu
of any
resulting loss is estimable, and believes these other matters are not likely, individually and in the aggregate, to
have a material adverse effecff
t on ouru financial position, results of operations or cash flows. However, litigation
is subjeb ct to inherent uncertainties and our view of these matters may change in the future. Were an unfavorabla e
outcome to occur, there exists the possibility of a material adverse impact on our financial position, results of
operations or cash flows for the period in which the unfavor
able outcome occurs, and potentially in future
periods.

Stockholders' Equity and Stock-Based Compensation

Stock Repurchase Program

In April 2019, our board of directors authorized a $1.0 billion stock repurchase program. This
authorization allows us to repurchase shares of our common stock over three years and is funded from working
capia tal. Repurchases may be made at management’s discretion from time to time on the open market, through
privately negotiated transactions,
transactions structurtt ed through investment banking institutions, block
purchases, trading plans under Rule 10b5-1 of the Exchange Act, or a combination of the foregoing. The

2014 Equity Incentive Planll

In April 2014, the board of directors and stockholders approved the 2014 Equiqq ty Incentive Plan (the
“2014 Plan”), effeff ctive on the first dayaa
that ouru common stock was publu icly traded, and simultaneously
terminated the 2004 and 2011 equity plans as to future grants. However, these plans will continue to govern the
terms and conditions of the outstanding options previously granted thereunder.

Awards granted under the 2014 Plan could be in the form of Incentive Stock Options (“ISOs”),
Nonstatutory Stock Options (“NSOs”), Restrit cted Stock Units (“RSUs”), Restricted Stock Awards (“RSAs”) or
Stock Appreciation Rights (“SARs”). The number of shares available for grant and issuance under the 2014
Plan increases automatically on Januaryrr 1 of each year commencing with 2016 by the number of shares equal to
3% of the outstanding shares of ouru common stock on the immediately preceding December 31, but not to
exceed 12,500,000 shares (the “2014 Plan Evergreen Increase”), unless the board of directors, in its discretion,
determines to make a smaller increase. Effeff ctive January 1, 2020, our board of directors authorized an increase
of 2,291,660 shares to the shares available for issuance under the 2014 Plan. In connection with our acquiqq sition

We have operations and a taxable presence in numerous jurisdictions outside the U.S. On December

red equaled the fair market value of the qualifying IP that resulted in the recognition
tax basis in the IP transferff
tax asset of $429.1 million, which was largely offsff et by a deferred tax liability of $343.3 million
of a deferredrr
associated witht
the future US tax on foreign earnaa ings arising from the transaction for the differff ence between the

Recognition of deferred tax assets is appropriate when realization of these assets is more likely than
not. We believe that all deferred tax assets are realizable with the exception of California, Canada, and U.K.
we recorded a valuation allowance of $82.6 million and $67.3 million as of
deferred tax assets. Therefore,
December 31, 2020 and 2019, respectively, against California, Canada, and U.K. deferred tax assets, since it is
more likely than not that these assets will be not be recognized.

ff

As of December 31, 2020, we had $245.1 million and $97.4 million of net operating loss carryforff wards
for federal and state income tax purposes, respectively, from the acquisition of Mojoo Networks, Big Switch
Networks and Awake Security. These federal and state losses will begin to expire in 2027 and 2029,
respectively. For foreign jurisdictions, we had combined foreign net operating loss carryf
orff wards of $12.8
million, which do not expire.

aa

We had a federal credit of $2.0 million from the acquisition of Awake Security,tt which will begin to
expire in 2038 and a California state credit of $128.7 million, which can be carrirr ed over indefinitely. For foreign
jurisdictions, we had $0.5 million of Canadian scientificff
research and expex rimental development tax credit
forwards, which will begin to expix re in 2034.
carry-rr

Utilization of the net operating losses and tax credit carryfrr orff wards may be subject to limitations due to

ownership change limitations provided in the Internal Revenue code and similar state or foreign provisions.

104

The Tax Cuts and Jobs Act enacted on December 22, 2017 requires a Transition Tax on previously
untaxed accumulated and curru ent foreign earnaa ings. Correspondingly, all undistrit buted earnings are deemed to
be taxed and distributions of the unremitted earnings do not have any significant U.S. federal income tax
impact. We have not provided for any remaining tax effeff ct, if any, of limited outside basis differff ences of ouru
nt. The determination of the future tax consequeqq nces
foreign subsidiaries based upon plans of future reinvestmet
of the remittance of these earnir ngs is not practicable.

Uncertain Tax Positions

We recognize uncertain tax positions only to the extent that management believes that it is more likely
than not the position will be sustained. The reconciliation of the beginning and ending amount of gross

million would affecff

tive tax rate if recognized.

t our effecff

Our policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a
component of income tax expense. We have recorded a net expense for interest and penalties of $0.1 million and
$0.2 million in the years ended December 31, 2020 and 2019, respectively. As of Decemberm 31, 2020 and 2019,
we recognized a liability for interest and penalties of $2.0 million and $2.2 million, respectively.

The statute of limitations for Federal and most states remain open for 2017 and forward. Some states
have net operating loss and tax credit carryforff wards, and thereforeff
itytt of
our foreign tax returns are open to audit under the statute of limitations of the respective foreign countries,
where the subsidiaries are located. It is possible that the amount of existing unrecognized tax benefits mayaa
decrease within the next 12 months as a result of statute of limitation lapses or payments to tax authorities in
certain jurisdictions; however, an estimate of the range

remain open to examination. The majora

cannaa ot be made.

None.

Item 9A. Controls and Procedures

Evaluation of Discii

losure Controls and Procedures

Management, with the participation of our Chief Executive Offiff cer (“CEO”) and our Chief Financial
Offiff cer (“CFO”), evaluated the effecff
tiveness of our disclosure controls and procedures as of December 31,
2020. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the
Exchange Act, means controls and other procedurdd es of a companynn that are designed to ensure that information
required to be disclosed by a companynn in the reports that it files or submits under the Exchange Act is recorded,
processed, summarized and reported, within the time periods specifieff d in the SEC’s rules and forms. Disclosure
controls and procedures include, without limitation, controls and procedures designed to ensure that informa
tion
required to be disclosed by a company in the reports that it files or submits under the Exchange Act is
accumulated and communm icated to the company’s management, including its principal executive and principal
financial offiff cers, as appropriate to allow timely decisions regarding required disclosure.

ff

Based on the evaluation of ouru disclosure controls and procedures as of December 31, 2020, our CEO
and CFO concluded that, as of such date, our disclosure controls and procedures are designed at a reasonable
assurance level and are effeff ctive to provide reasonabla e assurance that information we are required to disclose in
reports that we filff e or submit under the Exchange Act is recorded, processed, summarized, and reported within
the time periods specified in Securities and Exchange Commission (SEC) rules and forms, and that such
information is accumulated and communicated to our management,
including ouruu CEO and CFO, as
appropriate, to allow timely decisions regarding required disclosure.

Changen s in Internal Control

tt

over Finaii ncial Repoe

rtintt g

There were no changes in our internal controt

l over financial reporting identified in connection with the
evaluation required by Rule 13a-15(d) and 15d-15(d) of the Securities and Exchange Act of 1934, as amended,
that occurruu ed during the year ended Decembem r 31, 2020 that materially affecff
ted, or are reasonably likely to
materially affeff ct, our internal control over financial reporting.

Inherent Limi

taii

ii

tions of Internal Controls

tt

Our management, including our CEO and CFO, does not expect that our disclosure controls and
procedurdd es or our internal controls over financial reporting will prevent or detect all errors and all fraud. A
control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance
that the objectives of the control system are met. Because of the inherent limitations in all control systems, no
evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within
the Company have been detected. These inherent limitations include the realities that judgments in decision-
making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally,
controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by
management override of the controls. The design of any system of controls also is based in part upon certain
assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in
achieving its stated goals under all potential futurtt e conditions. Over time, controls may become inadequate
because of changes in conditions, or the degree of compliance with the policies or procedurd es may deteriorate.
Because of the inherent limitatioaa
tive control system, misstatements due to error or fraudaa mayaa
occur and not be detected.

Our management is responsible for establishing and maintaining adequate internal control over
financial reporting as defined in Rules 13a-15(f)ff and 15d-15(f) under the Exchange Act. Our internal control

over finff ancial reporting is a process designed under the supervision of our principal executive and principal
financial offiff cers to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of our financial statements for external purposes

Because of its inherent limitations, internal contrott
misstatements. Also, projections of any evaluation of effecff
tiveness 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 procedurdd es may deteriorate. Management assessed the effeff ctiveness of our internal controt
financial reporting as of December 31, 2020, based on the framework set forth by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013
framework). Based on that assessment, management concluded that, as of December 31, 2020, its internal

The effeff ctiveness of our internal control over financial reporting, as of December 31, 2020, has been
audited by Ernst & Young LLP, the independent registered public accounting firm that audits our Consolidated
Financial Statements, as stated in their report included in Item 8 of this Annual Report on Form 10-K, which
expresses an unqualifieff d opinion on the effecff
tiveness of our internal control over financial reporting as
