Corporate governance and stockholder outreach

Stockholder outreach and engagement

We believe that strong corporate governance practices include regular outreach and conversations with our stockholders. We regularly discuss our business, financial performance, industry dynamics, compensation, governance, and sustainability matters with our stockholders and welcome input on additional areas of importance to our stockholders. We actively seek engagement with stockholders of all sizes through a combination of virtual and in-person engagements, including investor conferences, one-on-one meetings where appropriate, and our annual meeting. For example, in the last 12 months, we have engaged with more than half of our 25 largest stockholders an aggregate of over 65 times. Our Board of Directors also reviews feedback from our stockholder engagement program as well as stockholder inquiries directly related to its responsibilities. These regular engagements allow us to obtain feedback on stockholders’ perception and understanding of our markets, business and industry and inform our Board of Directors directly to facilitate their oversight of management and the company. They have also influenced our communications, which include detail on key elements of our corporate strategy, annual financial targets and an articulation of our broader approach to our capital allocation priorities. We are intentional about all the ways a stockholder may engage with us and our information, including our website, and we routinely post information related to our strategy, business, financial performance, and technology evolution.

In June 2025, we published our 2024 Sustainability Report. During the first quarter of fiscal 2026, we proactively distributed information related to our sustainability programming to our top 25 stockholders, representing approximately 64% of our outstanding shares. Information contained on or available through our website is not incorporated by reference in or made part of this proxy statement and any references to our website are intended to be inactive textual references only.

Voting roadmap

This section highlights selected information about the items to be voted on at the Annual Meeting. It does not contain all information that you should consider in deciding how to vote. You should read the entirety of this proxy statement carefully before voting.

Proposal No. 1

Election of Class II Directors

Overview

Our Board of Directors currently consists of nine directors divided into three classes. Each class of our Board of Directors serves a three-year term, and the terms of the classes are staggered. At the Annual Meeting, three directors will be elected to fill positions in Class II. Joanne B. Olsen, Mary G, Puma, and Gary B. Smith, each of whom is a current Class II director whose current term expires at the Annual Meeting, are nominees for election at the Annual Meeting. Each of the nominees for Class II, if elected, will serve for a three-year term expiring at the 2029 Annual Meeting, or until such director’s successor is duly elected and qualified, or until such director’s earlier death, resignation, or removal from the Board. The nomination of these directors to stand for election at the Annual Meeting has been recommended by the Governance and Nominations Committee and approved by the Board of Directors.

Director qualifications

The Governance and Nominations Committee reviews candidates for service on the Board of Directors and recommends nominees for election to fill vacancies on the Board, including nomination for re-election of directors whose terms are due to expire. The Governance and Nominations Committee endeavors to identify, recruit and nominate candidates who possess a combination of wisdom, sound judgment, excellent business skills, maturity, and high integrity. In particular, the Governance and Nominations Committee seeks individuals with a record of accomplishment and senior leadership experience in their chosen fields who display the independence of mind and strength of character to be committed to representing the long-term interests of our stockholders, and the interests of other key stakeholders, including our customers, employees, business partners, and communities.

The Governance and Nominations Committee also seeks to ensure that the Board of Directors is composed of individuals with a broad range of backgrounds, who have complementary and differing skills sets, experiences, and relationships that align with Ciena's business and strategy. The Governance and Nominations Committee also sees the benefit of variety in terms of tenure and having a mix of individuals with a range of experience as a director, whether on Ciena’s Board or that of another company. This mix of background and experience includes ensuring that the Board includes individuals with experience or skills sufficient to meet the requirements of the various rules and regulations of The New York Stock Exchange (the "NYSE") and the SEC, such as the requirements to have a majority of independent directors, committees composed only of independent directors, and an audit committee financial expert. We also believe that having a range of perspectives represented on the Board strengthens Board oversight to the benefit of our stockholders. As required by the Governance and Nominations Committee Charter, the committee has developed and uses criteria for maintaining a balanced board of directors that possesses a mix of skills and characteristics, and it recommends criteria, establishes procedures for, and conducts an annual review of the Board, its committees, and directors, and reports to the Board on the results of the review.

In nominating candidates to fill vacancies created by the expiration of the term of a director, the Governance and Nominations Committee determines whether the incumbent director is willing to stand for re-election. If so, the Governance and Nominations Committee evaluates the director’s complementary experience, skills and relationships as described above in light of the current needs of the Board, as well as the incumbent director’s performance to determine suitability for continued service, taking into consideration, among other things, the director’s independence, the director's contributions to the Board, the value of the continuity of the director’s service, outside commitments in accordance with Ciena's overboarding policy, feedback from the Board's annual self-assessment and from stockholders, including the results of the stockholder vote at the most recent annual meeting, the director's attendance and participation at Board and committee meetings, and the director’s familiarity with Ciena’s markets, business and operations.

Board composition – continuing directors and nominees

* Reflects number of directors with this skill

The above charts reflect information for our nominees and continuing directors, and skills that our Board believes are important to the oversight of Ciena. Annually, we ask each of our nominees and continuing directors to identify their skills, experience, and other characteristics. Each of the nominees has consented to serve if elected. However, if any of the persons nominated by the Board of Directors fails to stand for election, declines to accept election, or is otherwise unavailable for election prior to our Annual Meeting, proxies solicited by our Board of Directors will be voted by the proxy holders for the election of any other person or persons as the Board of Directors may recommend, or our Board of Directors, at its option, may reduce the number of directors that constitute the entire Board of Directors.

Corporate governance and the Board of Directors

Ciena has adopted a number of policies and practices that highlight our commitment to sound corporate governance principles. We maintain a corporate governance page on our website that includes additional related information, as well as governance documents such as our bylaws, codes of conduct, Principles of Corporate Governance, and the charters for each of the standing committees of the Board of Directors. This information and documentation can be found on the "Corporate Responsibility – Governance Documents" page of the "Investors" section of our website at www.ciena.com.

Independent directors

In accordance with the current NYSE listing standards, the Board of Directors, on an annual basis, affirmatively determines the independence of each director or nominee for election as a director. The Board of Directors has determined that, with the exception of Dr. Nettles, who was an employee and executive officer of Ciena until he retired following the 2025 annual meeting of stockholders, and Mr. Smith, who is an employee and executive officer of Ciena, all of its members during fiscal 2025 are "independent directors," using the definition of that term in the NYSE Listed Company Manual. Also, as more fully described below, all members of the Board’s standing Audit, Compensation and Governance and Nominations Committees are independent directors, and all members of the Board’s standing Audit and Compensation Committees are independent directors in accordance with the additional listing standards applicable to those committees.

Communicating with the Board of Directors

The Board of Directors has adopted a procedure for receiving and addressing communications from all interested parties, including Ciena’s stockholders. Interested parties may send written communications to the entire Board of Directors (or any committee thereof), Ciena’s Chair of the Board of Directors, or all of the independent directors serving on the Board, by addressing communications to:

Ciena Corporation

7035 Ridge Road

Hanover, Maryland 21076

Attention: Corporate Secretary

Please address any communication by e-mail to ir@ciena.com with "Attention: Corporate Secretary" in the subject line.

Our Corporate Secretary and our General Counsel determine, in their discretion, whether the nature of the communication is such that it should be brought to the attention of the Board of Directors or a committee thereof, the Chair of the Board of Directors, or all of the independent directors. As a general matter, the Corporate Secretary does not forward spam, junk mail, mass mailings, job inquiries, surveys, business solicitations or advertisements, or offensive or inappropriate material.

Principles of Corporate Governance, Bylaws, and other governance documents

The Board of Directors has adopted Principles of Corporate Governance and other corporate governance policies that supplement certain provisions of our bylaws and relate to the composition, structure, interaction and operation of the Board of Directors. Copies of our Principles of Corporate Governance, bylaws, stock ownership guidelines and other governance documents can be found on the "Corporate Responsibility – Governance Documents" page of the "Investors" section of our website at www.ciena.com. You should review these documents for a complete understanding of these corporate governance practices, but some of the key elements of our strong governance policies and practices are summarized below:

Insider Trading Policy

We maintain an insider trading policy that applies to and governs the purchase, sale, and other dispositions of our securities by officers, directors and all employees, temporary employees, consultants, and contractors. We believe that our insider trading policy is reasonably designed to promote compliance with insider trading laws, rules, and regulations, and applicable NYSE listing standards, and helps protect our reputation for integrity and ethical conduct. The insider trading policy prohibits insider trading, tipping and pledging shares, trading put or call options, engaging in short sales, and hedging transactions involving Ciena’s securities. A copy of our insider trading policy was filed as Exhibit 19.1 to our 2025 Form 10-K. In addition, we also maintain a long-standing separate policy governing the ability of Ciena officers, directors and employees to enter into a pre-arranged trading plan pursuant to Rule 10b5-1 of the Exchange Act. It is Ciena's practice to comply with all applicable securities and state laws (including appropriate approvals by the Board or appropriate committee, if required) when engaging in transactions in Ciena's securities.

Codes of ethics

Code of Business Conduct and Ethics

We maintain a Code of Business Conduct and Ethics that sets standards of conduct for all of Ciena’s directors, officers and employees. The Code of Business Conduct and Ethics reflects Ciena’s policy of dealing with all persons, including our customers, business partners, employees, investors, and suppliers, with honesty and integrity. All employees are required to complete training on our Code of Business Conduct and Ethics, and we conduct recurring employee affirmations with respect to our Code of Business Conduct and Ethics and periodic training and communication related to specific topics contained therein.

Code of Ethics for Directors

We maintain a Code of Ethics for Directors, which supplements the obligations of directors under the Code of Business Conduct and Ethics and sets additional standards of conduct for our directors. The Code of Ethics for Directors outlines responsibilities of our directors with respect to their fiduciary duties, conflicts of interest, treatment of confidential Ciena information, communications and other compliance matters.

Code of Ethics for Senior Financial Officers

In accordance with the Sarbanes-Oxley Act of 2002, we maintain a Code of Ethics for Senior Financial Officers that specifically applies to Ciena’s CEO, CFO, and Controller. Its purpose is to deter wrongdoing and to promote honest and ethical conduct, and compliance with the law, particularly as it relates to the maintenance of Ciena’s financial records and the preparation of financial statements filed with the SEC. We intend to satisfy any disclosure requirement under Item 5.05 of Form 8-K regarding an amendment to, or waiver from, a provision of the Code of Ethics for Senior Financial Officers by posting such information on our website at www.ciena.com.

Each of these documents can be found on the "Corporate Responsibility – Governance Documents" page of the "Investors" section of our website at www.ciena.com. Copies of these documents may also be obtained without charge by writing to: Ciena Corporation, 7035 Ridge Road, Hanover, Maryland 21076, Attention: Corporate Secretary.

Board leadership structure

Separation of Chair and CEO roles

Although the Board of Directors does not have a formal policy on separation of the roles of CEO and Chair, Ciena has kept these positions separate since 2001. In fiscal 2025, in connection with the announced retirement of Dr. Nettles, our Executive Chair, the Board appointed Ms. Fitt as its independent Chair. The Board determined that the appointment of an independent Chair, in addition to reaffirming and strengthening the separation of power between the CEO and the rest of the Board, would further support our efforts to drive stockholder value by strengthening the independent oversight of strategy and risk, and ensuring that key strategic decisions made by senior management are reviewed by an independent Chair-led Board. Separating the Chair and CEO roles and having an independent Chair allows us to efficiently design, implement, and oversee corporate strategy that is consistent with the Board’s oversight role, while facilitating strong day-to-day executive leadership and execution.

The Board of Directors believes that its leadership structure is appropriate for Ciena. Through the appointment of an independent Chair, the independence of the Board’s committees, and the regular use of executive sessions of the independent directors, the Board is able to maintain independent oversight of our business strategy, annual operating plan, enterprise risk, and other corporate activities. These features ensure candor and a robust discussion of issues that are important to Ciena and its stockholders.

Board oversight of strategy

The Board of Directors believes that it is important to be deeply involved in overseeing and reviewing Ciena’s short- and long-term strategy. While management develops Ciena's strategic plans, the Board works closely with management to provide oversight and review of Ciena’s long-term strategic plan, annual operating plan, and strategy. The Board actively engages with management on the strategic plan, including routinely providing feedback, testing assumptions, and holding management accountable for management and the Company’s performance in accordance with the strategic plan. It also oversees Ciena's approach toward sustainability, ensuring its alignment with the long-term strategic plan and its design to grow business and stockholder value.

Because employee engagement, development, motivation, and retention are critical elements of our strategy, the Board annually reviews our "people strategy," a comprehensive overview of our human capital management practices, including compensation, benefits, wellness, growth and development opportunities, and inclusion and culture. Our full Board of Directors regularly reviews and has responsibility for corporate development activities including potential mergers and acquisitions and other strategic transactions. Strategy-related matters are discussed regularly at Board meetings, as well as at the committee level when appropriate. Such matters include:

❖ Long-term financial targets

❖ Three-year strategic plan and strategic scorecard

❖ Annual operating plan

❖ Key functional strategic initiatives

❖ Corporate development and strategic transactions

❖ Capital structure and capital allocation priorities

❖ Alignment of executive compensation with strategic and operating goals

❖ Human capital, talent management strategy and succession planning

While the Board and its committees oversee strategic planning, Ciena's management is responsible for executing on its business strategy. The Board believes that oversight and monitoring of strategy is a continuous process which is key to Ciena's long-term success. Among other things, the Board engages in the following activities to ensure oversight:

❖ The Board receives regular updates from and actively engages with Ciena's Chief Strategy Officer, other members of its executive team as well as leaders from various business functions.

❖ At least annually, the Board reviews Ciena's long-term strategic plan, annual operating plan, and budget. The Board also receives regular updates on these topics throughout the year and regularly engages on related topics with each standing Committee.

❖ As part of its annual review, the Board considers how its delegation of oversight to committees aligns with Ciena's strategy and evaluates whether the Board or a committee, or a multi-disciplinary approach, is appropriate given strategic direction and oversight considerations.

❖ At least annually, the Board conducts a formal review of Ciena's succession planning program, covering Ciena's leadership framework, talent and talent development across the company, and succession planning for the CEO, executive team, and other critical roles.

❖ Throughout the year and as part of a continuous process, the Board reviews and discusses matters related to Ciena's strategy with the executive team to ensure alignment with and progress toward strategic goals. The Board is focused on ensuring that business activities align with the plan and goals.

❖ The Board regularly receives updates on progress against particular objectives and imperatives detailed in Ciena's strategy.

❖ The Board and its committees regularly review global economic, geopolitical, market, industry, legal, and regulatory developments and trends.

❖ The Board regularly receives updates addressing Ciena's current markets and market expansion opportunities, key customers or segments, technological developments, and developments involving Ciena's competitors.

❖ To help reinforce industry and business knowledge, the Board periodically visits Ciena facilities, including research and development centers and labs, and receives presentations from business leaders and technologists on areas such as product development and strategy execution roadmaps. In addition, the Board is committed to education and reviewing recent trends, and routinely consults with management, legal counsel, and other advisors to keep the Board abreast of developments that may affect elements of the strategic plan.

Board oversight of risk

The Board of Directors believes that risk management is an important part of establishing, assessing, and overseeing Ciena’s business strategy. The Board, as a whole, oversees enterprise risk management. At the committee level, each committee has specific oversight responsibility relating to risks that could affect our corporate strategy, business objectives, compliance, operations and financial condition, performance, and reputation. The Board focuses its oversight on the most significant risks facing Ciena through an enterprise risk management process as well as other processes to identify, prioritize, assess, manage and mitigate those risks, including areas such as:

❖ Strategic, financial, and operational risk

❖ Compliance, legal, regulatory, and geopolitical risk

❖ Cybersecurity, enterprise and product security, AI, and business continuity

❖ Financial reporting and internal controls

❖ Corporate governance and compensation practices

❖ Human capital management and talent retention

The Board annually reviews and considers Ciena’s long-term strategic plan, its annual financial and operating plan, and periodically assesses enterprise risk management holistically and through a multi-layered process at the Board and committee levels. The Board and its committees receive regular reports from members of senior management on areas of material risk to Ciena, including strategic, operational, financial, information and cybersecurity, compliance, legal and regulatory risks. While the Board has an oversight role, management is principally tasked with direct responsibility for management and assessment of risks and the implementation of processes and controls to mitigate their effects on Ciena.

The Board’s leadership structure, with separate independent Chair and CEO roles, independent Board committees with strong chairs, the active participation of committees in the oversight of risk, and open communication with management, supports the risk oversight function of the Board. Each standing committee of the Board has risk oversight responsibilities and provides regular reports to the Board on at least a quarterly basis, as more fully described below under "Composition and Meetings of the Board of Directors and its Committees."

For more detail on the risk oversight responsibilities of each of our standing Board Committees, please see the descriptions of the responsibilities of each of the Board Committees below.

Cybersecurity and data privacy

As part of our Board of Directors’ oversight of risk management, the Board devotes time and attention to cybersecurity-related risks. The Audit Committee is responsible for overseeing cybersecurity, data privacy and information technology-related programs, policies and other efforts to manage or mitigate cybersecurity risks. As part of its standing agenda, the Audit Committee receives quarterly updates on cybersecurity risks and initiatives from our Chief Information Security Officer (the “CISO”). These updates have included reviews of our cybersecurity risk management efforts, including the development of relevant processes and policies, the implementation of technologies and systems, or use of third-party partners to safeguard our information systems, the conduct of education and training initiatives with employees and business partners, and incident response preparedness, including simulations and tabletop exercises. The Audit Committee regularly updates the Board of Directors on such matters. Separately, and in addition to such quarterly reporting, our Board of Directors also receives an annual update from our CISO on information and cybersecurity risks and related initiatives. These Board updates have included briefings from our CISO, as well as external counsel and third-party security advisors, which have included continuing education sessions and independent assessments, as our Board of Directors seeks to enhance its understanding of cybersecurity risk, leading practices and an evolving cyber threat landscape. Additional information regarding our cybersecurity governance, risk management and strategy is available in our 2025 Form 10-K.

Board education

Ciena provides a robust onboarding process for new members of our Board of Directors and comprehensive ongoing education and awareness communications for all Board members on key matters throughout the year. These include regular sessions with both internal and external advisors and subject matter experts. Through these sessions, the Board and its Committees receive regular updates on key corporate governance and compliance topics, evolving regulations or stockholder expectations, and leading practices. Our Governance and Nominations Committee regularly considers its continuing education practices, including key topics and various methods for providing such education to the Board. As a result of this review, the Board has previously augmented its regular education practices and conducted continuing education sessions focused on cybersecurity risk, climate risk and reporting, and generative artificial intelligence. These topics have included subject matter exploration, an understanding of potential impact on or application in our business, and our related governance practices. These sessions help shape the Board’s oversight of strategy and evaluate management’s risk analysis and mitigation efforts. At the request of the Governance and Nominations Committee, these sessions were conducted by members of senior management with responsibility for such programs as well as outside subject matter experts as appropriate. During fiscal 2025, all of Ciena’s directors were enrolled as members of the National Association of Corporate Directors (NACD) with access to its resources and programming, including with respect to director education.

Composition and meetings of the Board of Directors and its Committees

The table below details the composition of Ciena’s standing Board committees as of the end of fiscal 2025 and the number of Board and committee meetings held during fiscal 2025. Mr. Smith does not serve on standing committees of the Board of Directors.

❖ Chair

Each of our directors attended at least 75% of the total number of meetings of the Board of Directors and the committees on which they served during fiscal 2025. Ciena encourages, but does not require, members of the Board of Directors to attend the Annual Meeting, and eight of Ciena’s nine directors participated in the virtual Annual Meeting last year. Each of our directors is in compliance with our overboarding limitations contained in our Principles of Corporate Governance.

The Board of Directors has three standing committees: the Audit Committee, the Compensation Committee and the Governance and Nominations Committee. Each committee meets regularly and has a written charter that can be found on the "Corporate Responsibility – Governance Documents" page of the "Investors" section of our website at www.ciena.com. At each regularly scheduled Board meeting, the Chair or a member of each committee reports on any significant matters addressed by the committee.

Our approach to sustainability

Our sustainability strategy and program is designed to drive business and stockholder value, advance our overall strategy, and create competitive differentiation and advantage with our most important stakeholders, including our customers, employees and investors. Through our strategy, we work to develop products that lessen the environmental impacts of networks across the globe, create a work environment where people feel engaged and valued, invest in meaningful social impact in our communities, and maintain good corporate governance and security practices. Our sustainability strategy and programming are focused on the aspirations and pillars below, which are underpinned and supported by a strong foundation of leadership oversight, transparent reporting, impactful goals, and strong stakeholder engagement. More information about our sustainability programming, can be found in our latest Sustainability Report and in the "About Ciena" section of our website www.ciena.com

As provided in our Principles of Corporate Governance, the Board of Directors oversees management’s sustainability strategy and approach and ensures that our programs and progress are appropriately communicated to our stockholders. In addition, our Governance and Nominations Committee oversees our executive-level Sustainability Leadership Committee, including the execution of our sustainability strategy, the development and monitoring of sustainability goals, and the adequacy and accuracy of our related data. Information on some of our sustainability and governance practices, including related policies and programs, can be found in our latest Sustainability Report and in the "About Ciena" section of our website www.ciena.com.

Compensation philosophy and objectives

The Compensation Committee seeks to ensure that our compensation policies and practices promote stockholder interests and support our compensation objectives and philosophy. Ciena’s compensation program for our executive officers focuses on addressing the following principal objectives:

In making compensation decisions, the Compensation Committee also seeks to promote teamwork among and high morale within our executive team.

Compensation consultant

To assist in carrying out its responsibilities, the Compensation Committee is authorized to retain the services of independent advisors. For purposes of advice and consultation with respect to the compensation of our executive officers during fiscal 2025, the Committee engaged Compensia, Inc. ("Compensia"), a national compensation consulting firm. Prior to engaging Compensia, the Committee considered and assessed Compensia’s independence. To ensure Compensia’s continued independence and to avoid any actual or apparent conflict of interest, the Committee does not permit Compensia to be engaged to perform any services for Ciena beyond those services provided to the Committee. The Committee has sole authority to retain or terminate Compensia as its executive compensation consultant and to approve its fees and other terms of engagement. The Committee regularly, but not less than annually, considers the independence of its compensation consultant and determines whether any related conflicts of interest require disclosure.

In establishing executive compensation for fiscal 2025, the Compensation Committee relied upon Compensia to:

In addition to its advisory work regarding executive compensation and broad-based equity compensation during fiscal 2025, Compensia was engaged by the Compensation Committee to aid in evaluating the compensation of the non-employee directors as set forth below, to participate in and provide assistance with respect to the Committee’s annual compensation risk assessment, and to review the "Compensation Discussion and Analysis" included in this proxy statement.

Compensation Committee interlocks and insider participation

Dr. Ahmed, Ms. Olsen, and Messrs. Claflin and Gallagher, who comprised the Compensation Committee as of the end of fiscal 2025, are independent directors and were not, at any time during fiscal 2025, or at any other time, officers or employees of Ciena. During fiscal 2025, no member of the Compensation Committee was an executive officer of another entity on whose compensation committee or board of directors an executive officer of Ciena served.

Director compensation

Our director compensation program is designed both to attract and to fairly compensate highly qualified, non-employee directors to represent our stockholders on the Board of Directors and to act in the stockholders’ best interests. The director compensation program for fiscal 2025 was recommended by the Compensation Committee and approved by our Board of Directors. Our executive officers do not play any role in determining or recommending the amount of non-employee director compensation, except that Mr. Smith votes on the recommendations of the Compensation Committee in his capacity as a member of the Board of Directors.

Our Board of Directors includes Mr. Smith, who serves as our CEO. Mr. Smith does not receive any compensation for his service as a director. Information regarding the determination of Mr. Smith’s compensation can be found in the "Compensation Discussion and Analysis" and "Executive Compensation Tables" below.

During fiscal 2025, our Board of Directors also included Dr. Nettles, a Ciena executive officer who served as our Executive Chair of the Board until December 2025. Dr. Nettles retired at the end of his term at the 2025 annual meeting of stockholders and did not receive cash compensation for his service as a director. Information regarding equity compensation granted to Dr. Nettles during fiscal 2025 can be found in the tabular disclosure below.

Fiscal 2025 Board compensation

The Compensation Committee engaged Compensia to assist in evaluating the competitiveness of our director compensation program for the purpose of determining non-employee director compensation for fiscal 2025. As part of its process, the Compensation Committee considered an overview of the corporate governance environment, as well as recent trends and developments relating to non-employee director compensation. The Compensation Committee also specifically considered the amounts payable under and the various components of our director compensation program, the aggregate director compensation cost, in comparison to the boards of directors of the same group of peer companies that the Compensation Committee used in determining executive compensation, and the fact that no changes were made to director compensation the prior year. After considering those factors and based on the recommendation of the Compensation Committee, the Board of Directors determined it was in the interest of Ciena to make certain changes to director compensation for fiscal 2025 as disclosed below.

Cash compensation

Our cash compensation program for our non-employee directors for fiscal 2025 was as follows:

Under this program, our non-employee directors are not entitled to receive meeting attendance fees unless the Board, or any standing Board committee, is required to hold an unusually high number of meetings. In the event that the Board or a standing Board committee holds more than 12 meetings in a fiscal year, each non-employee director (as applicable) will be entitled to receive an additional $1,500 per meeting for the Chair, or an additional $1,000 per meeting for other members. In the event that the Board, or a standing Board committee, creates a special committee or subcommittee that holds more than three meetings in a fiscal year, each non-employee director serving on that committee or subcommittee will be entitled to receive an additional $1,000 per meeting. Our non-employee directors are also reimbursed for reasonable out-of-pocket expenses incurred in connection with attendance at Board and committee meetings.

The retainer fees set forth above are paid in quarterly installments. Meeting attendance fees, when applicable, generally are paid promptly following the end of the fiscal year.

Equity compensation

Our equity compensation program for our non-employee directors for fiscal 2025 was as follows:

The actual number of shares underlying restricted stock unit ("RSU") awards granted to directors is determined based on the grant date fair value of the award. Initial equity awards are made in connection with initial election or appointment to the Board of Directors, with the target delivered value prorated for the fiscal year based on the date of election or appointment. Initial equity awards vest on or about the one-year anniversary of the grant date. Annual equity awards are made on the date of each Annual Meeting and vest on or about the one-year anniversary of the grant date. Vesting of the RSU awards is subject to acceleration upon the director’s death, disability, retirement, or upon or in connection with a change in control of Ciena. Delivery of the shares upon vesting is subject to any applicable instruction provided by the director under the Deferred Compensation Plan described below. In connection with the appointment of an independent Chair, the Board conducted an assessment with its compensation consultant, considering compensation practices and benchmarks among our peers and the industry generally. Following that assessment, the Board approved a new annual equity retainer of $100,000 in target delivered value for the independent Chair beginning in fiscal 2025.

Director compensation limits

Our 2017 Omnibus Incentive Plan (the "2017 Plan") imposes a $500,000 limit on the compensation that can be awarded to a non-employee director in any given fiscal year, including the sum of (i) cash compensation and (ii) the grant date fair value of equity compensation under the 2017 Plan. This limitation, however, does not apply to the extent a non-employee director has been or becomes an employee of Ciena during such fiscal year. In addition, the Board retains discretion to provide further exceptions for one or more individual non-employee directors in extraordinary circumstances, such as service on a special transaction or litigation committee of the Board, provided that the director that is the subject of such exception may not participate in any decision with respect thereto.
