Annual Report

DEAR ARISTA NETWORKS STOCKHOLDERS:

Fiscal 2025 was another incredible year of progress and innovation for Arista, evidenced by our achievement of significant financial and operational milestones. I am so proud of the team's execution in continuing to deliver the ultimate combination of superior growth and profitability. We advanced our delivery of modern platforms enabling AI for networking and networking for AI.

Fiscal 2025 was another exceptional year full of progress for Arista. We delivered unprecedented revenue of $9.006 billion for our fiscal year 2025, an increase of 28.6% compared to fiscal year 2024. Meanwhile, we maintained a gross margin of 64.1%, the same gross margin as in fiscal year 2024. This strong performance resulted in net income for fiscal year 2025 of $3.511 billion, or $2.75 per diluted share, compared to net income of $2.852 billion, or $2.23 per diluted share, in fiscal year 2024.

Our exceptional performance is underpinned by significant innovation and development. For example:

We unveiled the R4 series platforms for AI, data center, and routed backbone deployment, which are built to deliver high performance, low AI job completion times, low power consumption, and integrated security, while helping customers reduce total cost of ownership.

We launched cognitive campus switches for the industrial edge, which bring the power, reliability, and operational simplicity of our Extensible Operating System ("EOS") to demanding industrial or outdoor environments.

We collaborated with industry leaders to deliver Ethernet for Scale-Up Networks (ESUN), which was unveiled at the OCP Global Summit in October 2025.

We acquired the VeloCloud® SD-WAN Portfolio from Broadcom, which enables customers to securely and efficiently interconnect data centers and distributed campus/branch offices while complementing Arista's existing portfolio.

We announced AI agents to streamline network operations with the combined power of open standards like MCP and the robust data and programmability of Arista's EOS and NetDL, empowering organizations to build, manage, and secure the networks of the future.

We have much to be proud of during our more than two decades of business and will continue to approach the future with the same hunger and quest for innovation as we did since our founding. We are well positioned with strong leadership and we look forward to bringing new products and technology to market that support and meet customer needs.

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

STOCKHOLDER OUTREACH

Executive Officers & Compensation

We regularly evaluate our corporate governance practices against prevailing best practices and emerging and evolving topics identified through stockholder outreach, current literature and corporate governance organizations. We are receptive and responsive to the perspectives of our stockholders as expressed through their engagement with us. As we have in previous years, we again engaged in meaningful, robust and proactive stockholder outreach throughout 2025 and into 2026, with participation by several of our independent directors, including our Lead Independent Director and the Chair of our Compensation Committee, senior leadership, and investor relations team.

Security Ownership

Other Matters

These discussions covered a wide variety of topics, including executive compensation, corporate governance, and sustainability. We take our stockholders' feedback on all matters, including executive compensation, seriously, as discussed further in the section entitled "Board of Directors & Corporate Governance - Stockholder Outreach." Furthermore, we are committed to meaningful outreach and engagement with our stockholders again in the coming year.

Appendices

In particular, we understand the importance of stockholder input on our executive compensation, particularly in light of our say-on-pay vote in 2025. As discussed in detail in the section entitled, "Board of Directors & Corporate Governance - Stockholder Outreach - Response to 2025 Say-On-Pay," members of our board of directors, including the Chair of the Compensation Committee, senior leadership and the investor relations team reached out to our stockholders for input specifically about our executive compensation program. During this focused outreach, we obtained feedback from 18 stockholders, collectively representing over 30% of our shares outstanding, including 10 of our top 25 institutional stockholders. Our Compensation Committee took the feedback from our stockholders seriously when considering the design of our executive compensation programs.

Proxy Summary

EXECUTIVE COMPENSATION HIGHLIGHTS

We are committed to aligning executive compensation incentives with the best interests of Arista and our stockholders. Therefore, a significant portion of the direct compensation opportunity for Named Executive Officers ("NEOs") is variable and "at-risk" because it is contingent on the achievement of defined performance goals.

Board and Corporate Governance

Furthermore, the equity vesting structure for our NEOs requires long service periods before equity awards vest in full, incentivizing retention and a long-term perspective. As discussed further in the section entitled "Executive Compensation," we believe that our executive compensation program is designed to align executive compensation with performance and promote retention.

As part of designing an effective executive compensation program, we have adopted many compensation-related best practices. The following compensation governance standards in our executive compensation policies and practices are currently in effect:

Environment

Arista is dedicated to responsible environmental practices that include climate change resilience, conservation of natural resources, pollution prevention and reduction of waste. We foster environmental awareness in our employees and partners, engaging them to reduce their footprint and waste, while collaborating to innovate powerfully efficient sustainable data technology solutions.

Proxy Summary

Arista's Environmental Policy, ethos, and culture of efficiency and innovation continue to drive our passionate and pragmatic approach to environmental sustainability. Through our Environmental Management System, Arista implements our objectives for achieving pollution prevention, environmental protection and monitoring, environmental sustainability, greenhouse gas ("GHG") emissions and climate risk management, and ongoing proactive monitoring and continuous improvement in the environmental performance of our operations.

Each new generation of our products demonstrates improved network capacity and energy efficiency for high performance data center installations. This evolution supports reductions in GHG emissions intensity and power consumption for our customers to advance their sustainability goals. In addition, Arista's new products continue to use power supplies that are rated 80-Plus Platinum or better, which helps reduce the total product power consumption and heat generated from the power supplies.

In 2025, Arista's Science-Based Targets were validated and approved by the Science Based Targets Initiative ("SBTi"), and Arista is now implementing these targets in earnest, with great dedication, with an expanded team to support greater net zero supplier and customer engagement. We continue to lead in transparency, disclosing the results of our third-party verified, comprehensive inventory of Scope 1, 2, and 3 GHG emissions. 2025 was a year of integration and internal capacity building to enhance cross-functional alignment to better serve our customer needs in the age of AI datacenter energy challenges and ever-increasing global resource constraints through further innovations in product energy and resource efficiency. We also convened a cross-functional team to complete an updated climate risk assessment to support enhanced readiness for potential transitional, market and physical risks.

Voting Proposals

Board and Corporate Governance

Proxy Summary

We are committed to integrating sustainability in every aspect of our products' life cycles across the value chain, from the materials and components that make up our products, to the end of life of the product, while meeting Arista customers' requirements and supporting their sustainability aspirations. For example, our certified recycling partners ensure environmentally responsible disposal in compliance with ISO 14001 standards. We continue to implement Design for Environment principles in our development process with the goal of minimizing the overall adverse environmental impact of our products. Specifically, Arista focuses on reducing material diversity and weight, selecting more environmentally friendly materials, designing for ease of disassembly and recycling, energy efficiency, longevity, upgradeability, and efficient and sustainable packaging.

Social Responsibility

Providing an amazing customer and product experience and technological leadership all starts with a great team. We are focused on growing our team of employees and prioritize providing resources that enrich their professional

development and personal total wellness. We believe that our ongoing success depends upon a skilled, satisfied, and valued workforce.

Executive Officers & Compensation

As such, Arista provides opportunities for our employees to gain necessary and desired skills and knowledge as well as upskill via a library of on-demand classes, webinars and in-person training.

Other Matters

Security Ownership

Appendices

Arista's employees participate in incentive stock and bonus plans that support our organizational philosophy of allowing employees to share in our performance and success. Our executive compensation program is designed to attract, retain, and reward performance and align incentives with achievement of Arista's strategic plan and both short- and long-term operating objectives. In accordance with our compensation philosophy established by the Compensation Committee and the board of directors, we believe our executive pay is well aligned with performance, creating a positive relationship between our operational performance and stockholder returns.

Proxy Summary

Board and Corporate Governance

Arista is all about respect, integrity, innovation, passion, pride, and trust. We conduct employee engagement surveys globally on an annual basis to gather information and feedback from our team members. We use a holistic organization-wide approach to respond to the results of the surveys, analyzing the data for potential actions and positive change that can be taken in the areas of leadership, communication, culture, inclusion, professional development and other areas. Beyond the workplace, the health and wellbeing of our colleagues is among our top priorities and in recognition of this, Arista offers ongoing wellness webinars and quarterly wellness weeks focused on mental, physical and financial health, social activity and professional development.

We strive to build an inclusive culture that encourages, supports and celebrates the voices of all our employees. It fuels our innovation and connects us closer to the customers and communities we serve. We believe that the voices of our employees are the ultimate barometer in evaluating our success. In 2025, Arista was extremely honored and humbled to receive a record number of external recognitions primarily based on enthusiastic employee feedback.

Voting Proposals

These recognitions include:

Executive Officers & Compensation

We are committed to developing a qualified and motivated workforce to power our continued evolution. The health and safety of our employees is among our top priorities. 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 our employees. We provide necessary and legally required training to employees on safety standards and protocols. Our Global Facilities team continues to proactively work to reduce and eliminate potential risks and ensures compliance with local laws and regulations. To evaluate performance, we regularly measure and monitor workplace safety and implement continuous improvements.

Security Ownership

We are aware of how our presence and partnership can positively impact others. Therefore, we are consciously and continuously working to systemically create positive change in our communities by partnering with impactful nonprofits through fundraising and sponsorship activities as well as volunteer events. The Arista Foundation's giving priorities are aligned with the United Nations' Sustainable Development Goals and are generally focused on education, hunger, environmental sustainability, and disaster relief. In 2025, we are proud to have:

Board and Corporate Governance

Proxy Summary

Through strategic nonprofit partnerships, pro bono work, volunteerism and philanthropy, our corporate responsibility efforts are focused on contributing to the creation of a better world. Going forward, Arista will continue to partner with nonprofit organizations that work to increase the number of individuals having access to education, decrease the number of individuals facing economic barriers and support the communities in which we operate and our employees work and live.

Supply Chain

We engage proactively with external stakeholders because manufacturing our products creates environmental and social impacts that extend far beyond the walls of Arista.

Voting Proposals

We engage responsibly and proactively with suppliers throughout our global supply chain to conserve resources, save costs, and ensure ethical practices and sustainable sourcing.

Q How do I vote? Q Can I change my vote?

If you are a stockholder of record, you can vote in one of the following ways:

by Internet at http://www.proxyvote.com, 24 hours a day, seven days a week, until 11:59 p.m. Eastern Time on May 28, 2026 (have your proxy card in hand when you visit the website);

by toll-free telephone at 1-800-690-6903 until 11:59 p.m. Eastern Time on May 28, 2026 (have your proxy card in hand when you call);

by signing, dating, and returning your proxy card (if you received printed proxy materials); or

by attending and voting at the Annual Meeting at https://www.virtualshareholdermeeting.com/ANET2026. To attend and participate in the Annual Meeting, you will need the control number included in your Notice of Internet Availability of Proxy Materials (the "Notice"), on your proxy card or on the instructions that accompanied your proxy materials.

If you are a street name stockholder, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to instruct your broker, bank or other nominee on how to vote your shares. Street name stockholders should generally be able to vote by returning an instruction card, or by telephone or on the Internet.

However, the availability of telephone and Internet voting will depend on the voting process of your broker, bank or other nominee. If you are a street name stockholder, you may not vote your shares at the Annual Meeting unless you obtain a legal proxy from your broker, bank or other nominee.

Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted.

Yes. Subject to the voting deadlines noted above, if you are a stockholder of record, you can change your vote or revoke your proxy any time before the Annual Meeting by:

Voting Proposals

entering a new vote by Internet or by telephone;

returning a later-dated proxy card;

notifying the Secretary of Arista Networks, Inc., in writing, at Arista Networks, Inc., 5453 Great America Parkway, Santa Clara, California 95054; or

Executive Officers & Compensation

attending and voting at the Annual Meeting at https://www.virtualshareholdermeeting.com/ANET2026.

Q Who is entitled to vote?

Security Ownership

Holders of our common stock as of the close of business on April 2, 2026,

the record date, may vote at the Annual Meeting. As of the record date, there were 1,259,169,438 shares of our common stock outstanding. In deciding all matters at the Annual Meeting, each stockholder will be entitled to one vote for each share of our common stock held by them on the record date. We do not have cumulative voting rights for the election of directors.

Other Matters

Appendices

Stockholders of Record. If shares of our common stock are registered directly in your name with our transfer agent, you are considered the stockholder of record with respect to those shares, and the Notice was provided to you directly by us. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote on your own behalf at the Annual Meeting.

Board and Corporate Governance

Proxy Summary

Street Name Stockholders. If shares of our common stock are held on your behalf in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of those shares held in "street name," and the Notice was forwarded to you by your broker or 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."

Voting Proposals

Q What is a quorum?

A quorum is the minimum number of shares required to be present at the Annual Meeting for the Annual Meeting to

Executive Officers & Compensation

be properly held under our amended and restated bylaws and Delaware law. The presence (including by proxy) of a majority of all issued and outstanding shares of our common stock entitled to vote at the Annual Meeting will constitute a quorum at the Annual Meeting. Abstentions, withhold votes and broker non-votes are counted as shares present and entitled to vote for purposes of determining a quorum.

Do I have to do anything in advance if I plan to attend the Annual Meeting?

Security Ownership

The Annual Meeting will be a completely virtual meeting, which will be conducted via a live webcast. You are entitled to

participate in the Annual Meeting only if you were a stockholder of record as of the close of business on April 2, 2026 or if you hold a valid proxy for the Annual Meeting.

Other Matters

You will be able to attend the Annual Meeting online and submit your questions during the meeting at https://www.virtualshareholdermeeting.com/ANET2026. To access the virtual meeting, you will need to enter the control number included in the Notice, on your proxy card or on the instructions that accompanied your proxy materials.

We encourage you to access the meeting prior to the start time. Online check-in will begin at 10:45 a.m.

If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of our board of directors. Jayshree Ullal, Chantelle Breithaupt and Sean Christofferson 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.

Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

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 16, 2026, 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.

How are proxies solicited for the Annual Meeting?

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.

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.

How may my brokerage firm or other intermediary vote my shares if I fail to provide timely directions?

Proxy Summary

Brokerage firms and other intermediaries holding shares of our common stock in street name for customers are generally

Board and Corporate Governance

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. Absent direction from you, 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.

Voting Proposals

Where can I find the voting results of the Annual Meeting?

We will announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report

Executive Officers & Compensation

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.

How many votes are needed for approval of each proposal?

Proposal One: The election of directors requires a plurality of the voting power of the shares of our common stock present

Other Matters

Appendices

in person or represented by proxy at the Annual Meeting and entitled to vote thereon to be approved. "Plurality" means that the nominees who receive the largest number of votes cast "FOR" such nominees are elected as directors. As a result, any shares not voted "FOR" a particular nominee, whether as a result of stockholder abstention or a broker non-vote (in other words, where a broker has not received voting instructions from the beneficial owner and for which the broker does not have discretionary power to vote on a particular matter), 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.

Board and Corporate Governance

Proxy Summary

Proposal Two: The approval, on an advisory basis, of the compensation of our named executive officers requires the affirmative vote of a majority of the voting power of the shares of our common stock present in person or represented by proxy at the Annual Meeting and entitled to vote on the subject matter to be approved. You may vote "FOR," "AGAINST," or "ABSTAIN" with respect to this proposal. Abstentions are considered shares present and entitled to vote on the subject matter, and thus, will have the same effect as a vote "AGAINST" this proposal. Broker non-votes will have no effect on the outcome of this proposal.

Broker non-votes will have no effect on the outcome of this proposal.

BOARD OF DIRECTORS & CORPORATE GOVERNANCE

Proxy Summary

Board and 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. The full text of our Corporate Governance Guidelines is available in the Governance section of our website at http:// investors.arista.com. 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.

Proxy Summary

Key Elements of Board Independence at Arista

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

Board and Corporate Governance

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:

7/9 of the directors are independent: We are committed to maintaining a substantial majority of directors who are independent of the Company and management. Except for our employee directors, all directors are independent.

Voting Proposals

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.

Lead independent director: Our lead independent 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.

Executive Officers & Compensation

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.

Security Ownership

In making the determination that Dr. Lavender is independent, the board of directors considered the Company's investment in Confidential Core AI, Inc. and the fact that Dr. Lavender is the co-founder of and currently serves as the Chief Technology Officer of Confidential Core AI, Inc. The board of directors determined that Dr. Lavender did not have a direct or indirect material interest in this transaction. Furthermore, payments made by us to Confidential Core AI, Inc. pursuant to such transaction did not exceed the greater of $1 million or 2% of Confidential Core AI, 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 Dr. Lavender's independence.

Director Commitments

Other Matters

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.

Appendices

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.

Proxy Summary

Board Leadership Structure

Board and Corporate Governance

We believe that the structure of our board of directors and its committees provides strong overall management of our Company and supports the risk oversight function of the board of directors. Our current Chairperson, Jayshree Ullal, is not independent under the listing standards of the New York Stock Exchange ("NYSE") as a result of her role as our CEO. Our board of directors reviews this structure annually and believes that Ms. Ullal's service as our Chairperson is appropriate and is in the best interests of our board of directors, our Company and our stockholders.

Voting Proposals

Our CEO 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 Chairperson 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. Our business is highly complex, with rapidly evolving technology, significant research and development investment, and sophisticated and demanding customers. Ms. Ullal brings essential knowledge and perspective as our CEO since 2008. Therefore, our board of directors believes that Ms. Ullal's dual roles facilitate the flow of information and communications between the board of directors and management as well as promoting alignment of our strategic direction with the operation of our business.

As discussed in more detail below, our board of directors believes that the responsibilities of our lead independent director appropriately and effectively complement our combined chairperson and chief executive officer structure.

Executive Officers & Compensation

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 Chairperson 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.

Security Ownership

The lead independent director communicates with the CEO, 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 independent directors when necessary 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 Structure

ensuring that the board of directors fulfills its oversight responsibilities in Company strategy, risk oversight and succession planning; and

Other Matters

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

Appendices

Our board of directors is divided into three staggered classes of directors. 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. Each class of directors is elected for a three-year term.

Board and Corporate Governance

Proxy Summary

Our board of directors has reviewed this structure, in consultation with the Nominating and Corporate Governance Committee, and believes that it is in the best interests of our company and our stockholders. The structure of our board of directors encourages directors to focus on longer-term objectives, fosters long-term planning, supports the development of important institutional knowledge, strengthens working relationships and protects stockholder value. We operate in a rapidly scaling industry that is intertwined with evolving frontier technologies, which requires the longer-term perspective, institutional knowledge, and strong working relationships that our board structure facilitates. In addition, our board structure helps us recruit highly qualified directors who are willing to commit to our strategic vision.

Board of Directors Evaluation Process

Voting Proposals

Our board of directors seeks to operate with the highest degree of effectiveness, supporting a dynamic boardroom culture of independent thought and intelligent debate on critical matters. The Nominating and Corporate Governance Committee oversees this process, which is led by the chair of the committee.

The annual assessment includes an evaluation of:

Board structure and composition;

Board and Corporate Governance

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 candidates, as well as the regular director nominee criteria described above. Under our Corporate Governance Guidelines, the Nominating and Corporate Governance Committee will consider candidates for our board of directors recommended by stockholders holding at least the minimum amount in market value of the Company's securities entitled to vote on the election of directors as set forth in applicable SEC rules and regulations 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, including SEC rules and regulations. In addition, we have adopted a "proxy access" procedure. Our proxy access bylaw allows a stockholder or a group of no more than 20 stockholders to include director nominees in our proxy materials for an

annual meeting of stockholders. More specifically, stockholders or groups of stockholders who have for at least three years maintained continuous ownership of at least 3% of our common stock may collectively include a number of director nominees not exceeding the greater of (A) two or (B) 20% of the number of directors in office. 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 certain written representations and undertakings as outlined in our amended and restated bylaws.

Stockholder Outreach

Security Ownership

Other Matters

We believe that effective corporate governance should include regular, constructive conversations with our stockholders and we believe that we have had an effective stockholder engagement program. The results of our 2025 advisory vote on say-on-pay impelled us to complement our commitment to robust stockholder engagement with additional stockholder outreach that focused on better understanding our stockholders' reasons for their 2025 say-on-pay votes. In 2025 and into 2026, members of our board of directors, senior management and investor relations participated in significant engagement with stockholders. We proactively contacted institutional stockholders representing over 40% of our outstanding shares. We met with stockholders who responded to our outreach and otherwise engaged in discussions with institutional stockholders representing approximately 45% of our outstanding shares. We sought and encouraged feedback from stockholders about our corporate governance practices, executive compensation and corporate responsibility programs, among other topics, with a particularly diligent focus on gathering and understanding stockholder feedback with respect to our executive compensation programs and related disclosures with the goal of taking specific actions to address the issues that contributed to the level of support for our 2025 advisory vote on say-on-pay, as discussed in more detail below in the section entitled "Response to 2025 Say-On-Pay." Our board of directors and its committees receive updates about our stockholder outreach and take the feedback of our stockholders under serious consideration and in some cases take specific actions to address that feedback. We believe that this open, ongoing and two-way dialogue with our stockholders strengthens our governance practices, enhances the accountability of our board of directors and supports effective, long-term oriented decision making.
